Sex and gender are both social constructions. Discuss Essay

Sex and gender are both social constructions. Discuss - Essay Example To achieve this, people invest the item with value, which every person acknowledge (therefore acting as though it has significance), and this explains people’s practices where money is concerned. However, currency is not just a thing, which occurs autonomously of human doings in the real world. In consequence, money is a social construction and a concept. It is incredibly real - calling money a social construct does not make it non-existent or imaginary. Nevertheless, its actuality is reliant on our ethnicity practices as well as our culture. This denotes that its classification, meaning, use and value are completely contingent on ethnicity. This paper will discuss sex and gender as social constructions. As society’s culture transmutes, so do their constructs. Certain constructs develop and then plunge into abandonment, and therefore, grow out of subsistence. Others remain; however, they vary from one civilization and historical episode to another. Sex and gender are su ch constructs. The behaviours and traits, which are believed to be feminine and masculine, differ vividly from one ethnicity and time interlude to another. Suitable ways of conduct oneself, the labour, which is allotted to gender sets, beliefs concerning natural talents and predispositions change drastically (Butler 2008). In addition, this adaptation and variation to circumstances, as well as social pressures underpins the notion that gender and sex are social constructions instead of some kind of essence, which begins from biology. Since if gender were shaped through physical sex, it would never change in this manner, but would be constant, simply as other naturally determined traits remain constant. Hence, gender differs with cultural transformation (Butler 2008). Gender is designated at birth rendering to bodily sex. Medical specialists inspect the infant's genitals and proclaim that the infant is a girl or a boy (except in the case where the new-born is intersex, where much eff ort is made to compel the kid into one faction or another). At that moment, the work inaugurates to fraternise the kid and impart the script, which matches with the gender that they have been allocated. In addition, most of people become pretty good on performing the fitting script. People learn which sentiments they are expected to exhibit, which undertakings they are expected to relish and shine at, as well as which ones they are expected to avoid. People also learn how to converse with one another, how to control their body language, and which type of hobbies and work they are expected to pursue. For many people it is not an appropriate fit, but people manage, or they learn ways of making those qualities about themselves, which do not match the script less visible. Nevertheless, for some people, it feels erroneous enough that they cannot just fit. For gender queer and trans gender,an individual, acting the new script or even an altered script completely, is the lone technique to render life liveable (Jackson, Steve & Sue 2006). Therefore, this description provokes a few queries such as why there exist only and why people require these scripts. People require the scripts as well as the evidently delineated categorical differences, because people cannot design hierarchy without variance. Hierarchy hinges on difference, therefore, people pick some physical

Business Law - Essay Example t as a separate legal entity, no legal requirements govern its formation, and owners have unlimited liability and equal decision making rights, unless specified (Miller 2012, p. 496). Limited partnership requires submission of certificate of limited partnership, acquisition of a charter for business operations, and a general partner and a limited partner while a limited liability partnership requires submission of a qualification for limited liability status (City Law School 2008, p. 31, 32). These identify such advantages as shared losses and pooled resources, and disadvantages such as long decision-making process, shared profits, unlimited liability, termination against a partner’s wish, and financial risk due to limited capital base (Mann and Roberts 2013, p. 678, 679). Agreement among owners, issuance of a charter, and submission of legal documents subject to Companies’ Act 2006 (Appendix 1) form a limited liability company (City Law School 2008, p. 23). It is a separate entity, as the case of Salomon v A Salomon & Co Ltd illustrates (McLaughlin 2015, p. 82). Limited liability and veil of corporation are some of the legal consequences of incorporation (Appendix 2) and transferable share capital and debentures are sources of capital. It therefore enjoys such advantages as wider capital base, expertise management, sustainability, transparency availability of accounts for inspections, and limited liability, but disadvantages such as slow decision managing and possible lost authority over the business. The doctrine of corporate veil governs operations of a limited liability company. It provides that liabilities are limited to the entity and shareholders and corporate members are lot liable for any right or duty of the entity, unless factors to piercing of the veil exist, subject to the case of Woolfson v Strathclyde Regional Council [1978] SC (HL) 90 (Dignam and Hicks 2011, p. 116). A private limited company can however not sell its shares to the public for

Advantages and Disadvantages of Computer Technology

Advantages and Disadvantages of Computer Technology Introduction:   Nowadays, computer technology is used in a variety of different ways for everyday life. This has become every bodys necessity whether they realise it or not. Everybody is using technology to some degree, let it be by setting an alarm clock or using a computerised self driving car. In everyday life, technology is used in education, industry, medical procedures, medical research, banking and business etc. In education, technology is used in researching information and many online learning courses (e-learning), technology is a necessity for people or children with disabilities e.g. might not be able to talk but learn how to use a computer and can communicate like everyone else. In relation to banking, e-banking transferring money from one account to another automatically, straight forward transactions no waiting/clearance period, and also people can see their account on line and check daily on account by using on-line services by a touch of a button. Throughout industries, computerised robots are used to assemble and test products instead of using manual labour. These robots are used to assemble products ten times faster than manual labour. In the advertising industry, many companies are becoming extinct because many people are advertising themselves by using Facebook, Done Deal and many other online services. In the medical field, the development of digital x-rays have saved a lot of time and has become interlinked with the other hospitals across the world in the research field for especially cancer patients, Alzheimers disease patients, doctors able to communicate by Skype etc and send information directly to help a patient straight away. Advantages of Computer Technology: Computer Technology helps to keep in contact with our family and re-connect with old friends or make new friends by using any services such as Facebook, Viber, WhatsApp, Skype and many more. People are using online dating to socialise and connect with others also. Many people can use Google maps to direct them from place to place instead of using the paperback version of maps. People can have a healthier lifestyle as many programs are issued online, such as diet and exercise programmes. In the medical field, robots are used to perform key-hole surgery on patients. This means the person is less open to infection, a quicker recovery time and hospital bed management systems have a leaner system in place (patient is less days in hospital). The majority of shopping nowadays is completed online. For example from groceries to buying a car. This all can be done by computer technology. Disadvantages of Computer Technology: Computer Technology has a massive impact on our private and public lives by using many social media sites such as Facebook, Instagram etc. With these types of sites, many people can be tracked through the location on their phone and this can be very dangerous. There is a wide variety of games that is available online. This has such an impact on the youth of today as it has caused a massive reduction in children reading books and playing sports. Many people cant socialise with one another as they feel the need to be on their phone either playing games or social media sites. In industry, computer technology is used by developing robots to assemble products in a short amount of time. This has led to unemployment as manual labour is kept to a minimum due to the robots being able to assemble products at a much faster speed than humans. In the medical field if computers break down and documents werent saved properly files can be lost, and also if malfunction with robotic machines that are operated by surgeons if not working properly, there will be delays in operating procedures, schedules will have longer waiting list. Computer Technology impacts our public and private life: Computer Technology has a massive impact in our public and private life. In relation to our public life businesses have gained a massive advantage in expanding and updating their company by using Computer Technology. Instead of posting letters to clients or other business people and waiting a day for the delivery, technology has invented the use of emails, faxing and video calls which is sent immediately. A lot of business people dont attend many meetings these days. They use video calling for important conferences. This reduces time and pressure on these people in travelling from one end of the country to the next. This software has developed programmes such as Microsoft and Excel. It is a way to set up rosters for employees and sort out accounts but there is a disadvantage with this. The invention of this has a big impact on people nowadays. Peoples vocabulary and math has demolished greatly by using these programmes. They can automatically calculate figures and check spelling by a click of a button compared to having to use calculators and exceptional vocabulary to write letters and complete accounts. All finances can be sorted online nowadays. This helps you check your account balance and transactions immediately instead of going to your local branch and queuing.   The difficult impact this has on people is that there is a lot of people that can hack into accounts; therefore people must set up correct security on their accounts to avoid this from happening. Entertainment can be seen through technology not only on the television. For example, the news from around the world, whether and it shows whether bank shares have increased or decreased for business people to see. Social media sites have been developed such as LinkedIn which is a great invention nowadays for people looking for employment and even employers seeking new and skilful employees for their company. In relation to our private life, technology is a great way to stay in contact with family members that may be aboard or old school mates by using Skype or other social media sites such as Facebook. Many people dont tend to socialise as much as they did. They use many social media sites and online dating to socialise with people. Technology is a great way that saves time and energy in relation to booking a holiday. Instead of standing in a queue and waiting to book flights or checking in luggage etc, this can be all completed online. Current development of computer technology in relation to healthcare: Computer technology is a basic essential in hospitals, nursing homes and home care environments; everything is computerised and electronically done so therefore everyone has to have general knowledge and understanding of computers starting with doctors, nurses, management, supervisors and healthcare assistants. The current development of computer technology in health care is that patient diagnosis and treatments is more efficient and no delays, this could save a persons life.   Doctors are able to connect with other Doctors in connection with second opinions and past and current findings on treatments, side effects etc.   Technology also helps the patient to understand what a doctor is explaining to them, so the patient can use the internet themselves and completing the physio therapy by using internet everyday for daily exercises. Everything is computerised so therefore bed management in hospitals and nursing homes have systems in place to let doctors, nurse managers etc   know how many bed are free for new patients care.  Ã‚   Systems are in place to make the hospital or nursing home aware of availability as healthcare is also a business so it is lean practising. Doctors use technology for all digital scanning systems e.g. MRI, Cat-Scan, X-Ray etc.   Doctors use computerised robots to perform surgeries and can get access information from hospitals and doctors across the world for reference. A Healthcare assistant will use technology so therefore to have a basic training is essential, because from using an electric hoist, electronic wheel chair, computerised sterilisation methods, in-house emailing system/shuttle systems for medication to be transported, accessing files for care plan, writing your journal notes, rosters of work and also helping a patient with their laptop, computer or television so that they can use it, this can relax the patient and help with the healing process. Legislations that should be aware of: Everybody should be aware of the different legislations that are in place. They are in place in order to protect individuals safety in a workplace or public or private life. One of our legislations are Safety, Health and Welfare at Work Act 2005, this outlines the duties of the employer and the employees that must be foreseen throughout working hours. Data protection Act 1988 and 2003 this act ensures personal data information is kept private and secure, accurate and up-to-date with records. Freedom of Information Acts 1998 and 2003 allows members of the public to have a legal right to see information held by certain bodies and everyone has a legal right to see anything they wish. Defamation Act 2009 is an act to protect any persons good name, if they are innocent and wrongfully exposed and their reputation could be damaged from false statements. Conclusion: By completing this assignment I have learned that I am more aware of computer technology and how it plays a massive role in both public and private life. Nowadays in the 21st century, we rely a lot on computer technology. Many people put a lot of their private life on the internet which leaves it open for other people to see which can result in robbery, people been very vulnerable and loss of communication as computers have taken over their lives. This is shown children for the future that there will be a major lack of communication skills and physical interaction with other individuals. Word count 1400

Effects of War Exposed in All Quite on the Western Front, Bury the Dead

Effects of War Exposed in All Quite on the Western Front, Bury the Dead, and Paths of Glory      Ã‚  Ã‚  Ã‚   "From the happy expression on their faces you might have supposed that they welcomed the war. I have met with men who loved stamps, and stones, and snakes, but I could not imagine any man loving war." Margot Asquith revealed her discontent with war in this quote. War is defined in the American Heritage Dictionary as a concerted effort or campaign to combat or put an end to something considered injurious. A rather contradicting definition from the dictionary when one examines war's true meaning and the effect it has on mankind. Wars do not put an end to something considered injurious, war starts them. War stems from human greed and ignorance and is often used as a tool by men to seek fame and glory. People remember the glory of Alexander the Great, Hannibal, and Napoleon but forget the number of deaths caused by these so-called heroes. War is about death and the destruction of the human character and spirit. World War I, not only claimed millions of lives , but left deep scars in the memories of those who survived. Disillusioned and disheartened, these young people became known as the Lost Generation. Even though the cost of war was staggering, its psychological effects had no boundary. The soldier's greatest struggle during war is not physical, but mental and spiritual.   Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚   A war novel that gives its reader an insight into the lives of soldiers during WWI, All Quiet on the Western Front, written by Erich Maria Remarque, is considered the greatest war novel of all time.

Research Paper on Elctrocardiogram (Ecg)

Introduction The major function of the heart is to force blood in to a closed system of blood vessels within which the blood is confines and circulated to the entire body. Heart’s activity can be compared to a muscular pump equipped with one way valves. With each heartbeat, an electrical impulse travels through the heart and causes the heart muscle to squeeze and pump blood from the heart. These electrical impulses, transmitted through the heart, are spread throughout the body. This electrical activity of the heart can be detected on the body’s surface and recorded with an instrument called an electrocardiograph.A graphic record of heart activity is called an electrocardiogram. An electrocardiogram is also called an EKG or ECG. Sometimes the test is called a 12-lead EKG or 12-lead ECG. This is because the heart's electrical activity most often is recorded from 12 different places on the body at the same time. A healthcare provider may recommend an electrocardiogram if a person has signs and symptoms that suggest a heart problem (National Institutes of Health, 2010). Examples of signs and symptoms may include chest pain, breathing problems, unusual heart sounds, palpitation etc.However, this test can screen for early heart disease that has no symptoms. An ECG may be done as part of a routine health exam and may be used for routine screening before major surgery. Also, this test can be ordered to check how well heart medicine or a medical device, such as a pacemaker, is working (National Institutes of Health, 2010). ECG results can be used by the healthcare provider to help plan treatment for a heart condition. Different types of electrocardiograms Many heart problems are present all the time, and thus a commonly used 12-lead ECG test is sufficient to detect any of these problems.However, certain issues, such as those related to irregular heartbeats, can come and go. They may be present for only a few minutes out of the day, or while performing spec ific daily activities (e. g. , exercising). In these situations, special types of ECGs are used to help diagnose these types of problems. The different ECGs that can be used in these situations are: †¢Stress test: During stress testing, exercise or medications are used to make heart beat faster and work harder while conducting the ECG. †¢Holter monitor: This is a portable device that records the electrical signals of he heart for a full 24 to 48 hour period (Pagana & Pagana, 2010). This is also called as an ambulatory ECG, as daily activities can be performed while wearing it. †¢Event monitor: This is a portable device like holter monitors, but they can be worn for more than a month and are used to detect abnormalities of short duration and that occur infrequently. This paper discusses 12-lead ECG that is most commonly used in health care settings. Explanation of ECG test and related physiology A typical ECG has three distinguishable waves or deflections.The relations hip between the deflections waves of an ECG and sequential excitation of the heart is shown below (The Biology corner, 2011) Figure1. The sequence of excitation of the heart related to deflection waves of an ECG tracing. The first wave, the small P wave, lasts about 0. 08 s (Marieb & Mitchell, 2010). This wave results from movement of the depolarization wave from the heart’s SA node through atria. The second wave, the QRS complex is the largest waves of all the three waves. It results from ventricular depolarization and precedes ventricular contraction.Average duration of the QRS complex is 0. 08 s (Marieb & Mitchell, 2010). A prolonged QRS complex may indicate a right or left bundle branch block in which one ventricle is contracting later than the other. The third wave, the T wave is caused by ventricular depolarization and typically lasts about 0. 16 s (Marieb & Mitchell, 2010). The P-R interval represents the time between the beginning of atrial depolarization and ventricu lar depolarization and it lasts about 0. 16 to 0. 18 s. A longer interval may suggest a partial AV heart block caused by damage to the AV node (Marieb & Mitchell, 2010).Lack of impulses through AV node may indicate a total heart block. The Q-T interval is the period from the beginning of ventricular depolarization and repolarization that normally lasts 0. 31 to 0. 41 s (Marieb & Mitchell, 2010). The shorter Q-T interval may indicate tachycardia, and a longer may indicate bradycardia. Normal/abnormal findings In a healthy heart, the size, duration and timing of the deflection waves tend to be consistent. For this reason, changes in the pattern or timing of the ECG may reveal a diseased or damaged heart or problems with the heart’s onduction system (Marieb & Mitchell, 2010). An ECG gives two major kinds of information. First, by measuring time intervals on the ECG, a doctor can determine how long the electrical wave takes to pass through the heart (Pagana & Pagana, 2010). Findi ng out how long the wave takes to travel from one part of the heart to the next shows if the electrical activity is normal or slow, fast or irregular. Second, by measuring the amount of electrical activity passing through the heart muscle, a cardiologist may be able to find out if parts of the heart are too large or are overworked (Pagana & Pagana, 2010).Normal ECG values include a heart rate of 60 to100 beats /min and an even and consistent heart rhythm (National Institutes Of Health, 2010). Abnormal ECG results may indicate a sign of following health issues: †¢Abnormal heart rhythms (arrhythmias) †¢Cardiac muscle defect †¢Congenital heart defect †¢Faster than normal heart rate (tachycardia) †¢Slower than normal heart rate (bradycardia) †¢Heart valve disease †¢Inflammation of the heart (myocarditis) †¢Changes in the amount of electrolytes (chemicals in the blood) †¢Past heart attack †¢Present or impending heart attackAn electrocardi ogram may be performed to diagnose additional conditions which are not listed above. ECG Procedure and Patient preparation The patient does not need to take any special steps before having an electrocardiogram. However, the nurse may ask about the medicines the patient is taking as some medicines can affect the results. Also, the nurse performing the test may instruct the patient to avoid exercising or drinking cold water immediately before an ECG, as it may cause false results. The procedure of an ECG is painless and harmless. A nurse will attach soft, sticky patches called electrodes to the skin of chest, arms, and legs.The patches are about the size of a quarter. Often, 12 patches are attached to patient’s body. This helps detect the heart's electrical activity from many areas at the same time. The nurse may have to shave areas of the skin to help the patches stick. After the patches are placed on patient’s skin, he/she will lie still on a table while the patches de tect heart's electrical signals (Pagana & Pagana, 2010). During the ECG recording, nurse may instruct the patient to lie quietly for 10-20 seconds, because the electrocardiograph will detect any muscle or body movement.A machine will record these signals on graph paper or display them on a screen. The entire test will take about 10 minutes. After an electrocardiogram, the nurse will remove the electrodes (soft patches) from the patient’s skin. Patient may develop a rash or redness where the EKG patches were attached. This mild rash often goes away without treatment. Patient usually can go back to his/her normal daily routine after an ECG. Summary An electrocardiogram is a painless, non-invasive diagnostic test that records heart’s electrical activity.This test shows, how fast a heart beats, whether the rhythm of the heart is regular or irregular and the strength and timing of electrical signals as they pass through each part of the heart. Healthcare providers use this test to study and detect many heart problems and the results of this test can also suggest other disorders that affect heart function. Conducting an ECG when appropriate is a primary step in increasing a patient’s survival, and leads to a clearer, gained understanding of what is actually happening to a patient’s heart.

Slavery And Plantation In Trinidad And Tobago History Essay

Bondage and Plantations have ever been linked, driven by economic aims ( Williams 1994 ) , from the earliest period of sugarcane cultivation in the Caribbean. Despite the complexness of the events and fortunes that created this relationship, sugar growing and slavery both were dining during the comparatively peaceable early old ages of the eighteenth century. The European demand for sugar had been increasing, and England ‘s sugar demands led the battalion. The British islands like T & A ; T were a mono-crop society, with few colonists turning anything but sugar caneThe Business of SlaveryThe Triangular Trade is a term normally used in treatments of the slave trade. Slaves would be brought from Africa to the plantations, which would direct sugar and other local goods to Europe, who would in turn send goods to Africa. The goods normally sent to Africa were guns and other manufactured points because there was no industry in Africa. In the West Indian islands like T & A ; T, nevert heless, the merchandising of slaves was an of import portion of the economic system. The demand for more slaves was ever greater than the market could supply, and the West Indian companies were opened up in the 1700s to outside trade to assist supply extra slaves to settlements that produced sugar. The Gallic encouraged this trade on their islands by relieving slaves from most import and export revenue enhancements.Life on PlantationsWorking Conditionss: Slave Labour in Plantations ‘aˆÂ ¦the toughest season, a season of labor from dawn to twilight, bare mortise joints and calves stung by cowitch, knotted musculuss slashed by cane foliages that cut like consecutive razors, dorsums split unfastened by the whipaˆÂ ¦ ‘ The plantation land consisted of cane-fields, proviso evidences, forest and grazing land. Each plantation owner preferred to hold more than 200 estates of cane land. Provision evidences were used by the slaves to cultivate root harvests, plantains and veggies for nutrient. The forest provided timber and firewood and the grazing land was used for croping cowss ( Handler 1965 ) . The cane Fieldss had either freshly planted canes or ratoons. The ratoons were new shoots turning from old cane roots which were left in the land after a old harvest of cane was harvested. Normally a ratoon field was less productive. A typical sugar estate had factory edifices such as the factory, boiling house and hardening house. Around these mill edifices there were other smaller edifices and sheds in which, blacksmiths, wheelers, carpenters, Masons, Coopers and other artisan slaves worked. There would besides be a little â€Å" infirmary † for ill slaves, and a little â€Å" gaol † which kept slaves who were being punished. There were storage suites for tools and supplies and sheds which sheltered farm animal or stored cane rubbish or bagasse which was used as fuel. Not far from the mill edifices were little houses in which the European directors and supervisors lived. They were by and large superintendents, book-keepers, skilled craftsmen and office staff. In the biggest house lived the estate proprietor. The slave quarters were some distance off from the places of the directors. A work twenty-four hours consisted of 15-16 hours a twenty-four hours, during harvest clip and, could travel on during crop and milling for 16-18 per hebdomad 7 yearss a hebdomad and harmonizing to Stampp ( 1956 ) the slaves were given the undertaking to fix the land for seting. Their normal on the job twenty-four hours began before dawn and ended after sunset. They cleared the grass and shrubs by weeding and combustion ( kids between the ages of six and ten might be active as H2O bearers while kids between the ages of 10 and 12 were organized into packs and set to weeding ) . Cane holes were dug and into these cane tops were planted. As the cane grew, packs of slaves manured the field and weeded shrubs that sprang up around the cane workss. Female slaves did much of the weeding and the manuring. After 12 to 15 months the cane was now mature. The field was set afire to fire off the foliages from the cane chaffs and at the same clip to acquire rid of serpents which lived at that place . The field slaves, utilizing cutlasses, so cut the cane chaffs, packed them in packages and loaded them on to ox-drawn carts which transported them to the factory. At the factory, the cane was crushed and the juice flowed through troughs to big metal containers. The cane rubbish was removed and stored for usage as fuel for the boilers. The juice in the big containers was clarified by heating and the add-on of a little measure of calcium hydroxide. This clarified juice was so ladled into a Cu boiler in which it was boiled. After a piece, the juice from this Cu boiler was ladled into a smaller boiler and was boiled once more and so still further in a yet smaller boiler. By so, it had changed into gluey sirup which was allowed to chill, and so poured into wooden hogsheads standing on beams in the hardening house. Through little holes at the underside of the hogsheads, molasses seeped out and was collected in containers set below the beams. After about three hebdomads, the staying siru p in the hogsheads crystallised to organize sugar. The sugar remained in the hogsheads which were subsequently packed into ships for export to Europe. Some estates besides manufactured rum by fermenting juice from the first boiling and about the same measure of molasses. Almost all of this specialized work carried out in the industry of sugar and rum was done by skilled artisan slaves who were extremely valued by their proprietors. During the milling season, slaves worked in displacements throughout the twenty-four hours and dark. Even after the harvest season was over, the estate proprietor did non let his slaves to be idle. The Fieldss had to be prepared for the new harvest, weeding and manuring of the ratoons had to be done, and fixs to drainage and irrigation canals, fencings and edifices had to transport out. Work was even found for kids from the age of six old ages old. They collected firewood, cut grass to feed farm animate beings and fetched imbibing H2O to slaves working in the Fieldss. The plantation proprietors did non desire their slaves to affect themselves in idle conversation since they felt that the discontented slaves may utilize the juncture to plot rebellion.PunishmentsWhile each plantation had its ain set of societal, spiritual, and labour codifications, all had the basic format for an instilled hierarchy in which the slave maestro reigned as generalized anxiety disorder. He maintained the component of slave wretchedness, by commanding the grade of hurting ( Starobin 1974 ) . Treatments wer e given such as mutilation, stigmatization, chaining, and slaying which were purportedly regulated or prohibited by jurisprudence. Whippings, whippings, drownings, and hangings were every bit unpredictable as they were gruesome. It was clear to plantation proprietors that bondage could non last without the whip ( even though proprietors were out to intentionally kill or maliciously mangle a slave ) . Males and females were whipped randomly. The badness of floging depended on the figure of shots to the type of whip. Fifteen to twenty ciliums were by and large sufficient, but they could run much higher. Other points used for penalties included stocks, ironss, neckbands, and chainss. It was besides platitude that adult females could be raped by the proprietor of the plantation, his boies or, any white male.Methods of ControlThe White plantation proprietors in T & A ; T used assorted methods to keep complete control over their slaves. Their chief method was that of â€Å" divide and regulation † . Members of the same folk were separated on different plantations to forestall communicating between them. The purpose behind this was to forestall any programs to arise if they were together. This separation, ne vertheless, created a job of communicating, since the plantation would hold different groups of slaves talking different linguistic communications. Therefore, the plantation owners had to happen a manner to pass on with their slaves. Soon a new linguistic communication, known as Creole, developed and this became a common lingua among the slaves. When the British took control of the twin islands in the 19th century, English words were injected into the linguistic communication and it became the footing of the Creolised linguistic communication. Slaves were besides prevented from rehearsing their faiths. Quite a few slaves were Muslims while many others had their ain tribal beliefs. But since the Christian plantation owners saw non-Christians as heathens, they made sure that the slaves could non garner to idolize in the manner they were accustomed when they lived in Africa. Subsequently Christian missionaries were permitted on the plantations and they were allowed to prophesy to the slaves on Sundays. In clip, many of them were converted to Christianity ; it was the general feeling that the born-again slaves became docile and was non willing to back up rebellion on the plantations. Another means of control was the creative activity of a category system among the slaves. Field slaves formed the lowest group, even though some of them had particular accomplishments. The lowest ranking slaves, the anchor of the plantation economic system, were the field slaves. The field slaves were divided into ‘gangs ‘ harmonizing to their physical strength and ability, with the strongest and fittest males and females in the first pack. The inducement used to promote difficult work, was ciliums of the cart whip, which were freely administered by the drivers, who were ‘privileged ‘ slaves under the superintendent ‘s supervising. Higher up the slave hierarchy were the artisan slaves such as blacksmiths, carpenters and Masons, who were frequently hired out by the plantation owners. These slaves besides had chances to gain money for themselves on assorted occasions. Still higher up in this category system were the drivers who were specially selected by the White plantation owners to command the other slaves. The domestic or house slave had a particular topographic point in this agreement, and because they worked in the maestro ‘s house and sometimes having particular favors from the maestro, they held other slaves in disdain. Normally, the slaves in the lowest round of this societal ladder were the 1s who rebelled and frequently domestic slaves were the 1s who betrayed them by describing the secret plans to their maestro. Then there were divisions based on coloring material. In the early yearss, it was comparatively easy for a pure African to lift to the degree of a driver. But mixtures occurred through the birth of kids as a consequence of brotherhoods between White work forces and black adult females ( mulatto ) , White work forces and mulatto adult females ( mestee ) and mulatto work forces and black adult females ( sambo ) . Some slaves of wining coevalss therefore had lighter skin colors, and the White plantation owners discriminated in favor of them. These slaves with White male parents or White relations were placed in places above those of the field slaves. This was the beginning of color favoritism in the Guyanese society. Of class, in all of this, the Europeans – the Whites – occupied the highest round of the societal ladder and they found willing Alliess among the assorted or colored population who occupied the intermediate degrees. The pure Africans remained at the lowest deg ree Womans and Slavery in the Plantations Harmonizing to Bush ( 1990 ; 33 ) the primary ground for the presence of adult females in T & A ; T during the clip of bondage was due to their labour value. In the early yearss of bondage, plantation proprietors attempted to bring forth healthy forms of reproduction and encourage matrimony, but found it was economically unlogical to make so. Alternatively, it was more profitable to buy new slaves from Africa ( until the continued supply of female slaves being delivered from across the Atlantic was threatened by abolitionist force per unit area in the 18th century ) . Girls worked on estates from the early age of four. Occupations for misss between the ages of 12-19 varied from field work, to stock work, to domestic work, to rinsing e.g. vesture, dishes, etc. ( Reddock 1985 pg. 64 ) , . Other signifiers of work for mature adult females included accoucheuse, doctoress, and housekeeper. European plantation proprietors by and large regarded most slave adult females as suited for field w ork, which consisted of occupations such as delving holes for canes, weeding, and hoeing. In Jamaica, the bulk of adult females between the ages of 19 and 54 were working in the Fieldss. By the late eighteenth and early 19th century, there were more adult females working in the field than work forces due to their lower mortality rates. Despite the common stereotype whereby work forces are stronger and more physically capable than adult females, it can be argued that adult females were as of import, if non more of import, to field work during the period of bondage in T & A ; T. The importance of adult females in the plantation economic system is reflected in the monetary value of female slaves between 1790 and the terminal of the slave trade. The monetary value for a â€Å" new † male slave was about ?50-?70, while the monetary value for a new female slave was about ?50-?60. ( Bush, 1996:33 ) Apart from businesss such as doctoress, accoucheuse, and housekeeper, which were considered to be higher employment places for slave adult females during the clip, the slave elite was about wholly made up of work forces. Womans were confined to contending for lower places in the socio-economic hierarchy and were ever excluded from the more esteemed and skilled occupations ( i.e. woodworking ) . Among the limited sum of businesss available to Trinbagonian slave adult females, the most esteemed occupation was found to be nursing. One manner in which adult females slaves would on occasion accumulate income and resources for themselves was through sex trade ( Morrissey 1989 pg. 69 ) . This was a common manner for adult females slaves to salvage money for freedom, peculiarly in the eighteenth and 19th centuries in T & A ; T. The bulk of enslaved domestic workers in towns were expected to back up themselves through harlotry.Culture of Slavery and Plantation lifeHomePlantation slaves were housed in slave ‘s cabins. Small, impolitely built of logs with clapboard turnouts, with clay tinkling. Floors were packed soil. They were leaky and draughty and the combination of moisture, soil, and cold made them diseased environments. On the plantation, the slaves were housed in edifices which were some distance off from the maestro ‘s house. Most of these slave houses had thatched roofs and walls of old boards or of wattle and clay. The floor was the Earth itself and there were no furniture except some fundamenta l pieces that the slaves managed to do.ClothingSlaves were non well-clothed ; they had unequal vesture for people engaged in heavy labor all twelvemonth. Children would dress in long shirts. Men possessed small besides with two shirts and two cotton bloomerss. Womans were provided with an deficient sum of fabric and made their ain apparels. The fabric was inexpensive stuff, produced in England that was dubbed â€Å" Negro fabric † . The slaves besides obtained a vesture allowance approximately every twelvemonth. The work forces received a harsh woolen jacket, a chapeau, about six paces of cotton, and a piece of canvas to do a brace or two of pants. Womans received the same allowance as the work forces, but kids received none. The kids remained bare until they were approximately nine old ages old, or were given cast-off vesture that their parents managed to happen or were able to buy.FoodThe nutrient was by and large equal in majority, but imbalanced and humdrum. Typical nutri ent allowance was a batch of maize repast and three to four lbs of salt porc or bacon per hebdomad per individual. This diet could be supplemented by veggies from their gardens, by fish or wild game, and molasses ( non normally ) . The slaves prepared their ain nutrient and carried it out to the field in pails. While the slaves were provided with certain groceries by the maestro, they raised their ain subsistence harvests of veggies, plantains and root harvests on little garden secret plans that the maestro allowed them to utilize. However, they could merely make their personal agriculture on Lord's daies when they had no work on the plantation. They besides took the chance to angle on Lord's daies in the nearby canals, the rivers or the ocean. Each grownup slave was given one lb of salt-cured pod fish every Sunday by the plantation proprietor. The salt-cured pod fish was imported from North America. A kid slave was given a smaller allotment. On particular Christian vacation, there was an extra allowance of about a lb of beef or porc, some sugar and a measure of rum.ReligionThe general position held by the plantation proprietors was that the African slaves did non keep to a system of beliefs that could be described as a faith ( Mbiti 1969 ) . At best – so the members of the plantocracy and the church that served them felt – their beliefs amounted to nil more than pagan superstitious notion. Not a few of them, possibly, felt that the Africans were incapable of spiritual sentiment. But the Africans held spiritual beliefs derived from their fatherland. It may be utile to observe that some of the slaves, peculiarly these who came from the Fula-speaking country of Senegambia, were Muslims. The pattern of the plantation owners of dividing tribesmen from one another, and of detering the collection of slaves for any purpose whatsoever, was non calculated to let Islam to last. Again, the little figure of African Muslims that came to plantations in T & A ; T lacked the leading of Imams and the ownership of the Qur'an. Then, excessively, the plantation life did non impart itself for long supplications at fixed times, worship on a set twenty-four hours, fasting at prescribed periods, or banqueting on vacations which did non co-occur with those observed by the plantocracy. On the other manus, autochthonal African spiritual beliefs, which became labelled as â€Å" obi † , survived the troubles of estate life. But these beliefs underwent important alterations although they remained clearly â€Å" African † in construction ( Saraceni 1996 ) . Three factors were chiefly responsible for these alterations. In the first topographic point, African spiritual thoughts were capable of alteration in response to the new circumstance of estate life. Second, the pattern of African faith was frowned upon by estate governments. This meant that the faith could merely be practised in secret and irregularly. The consequence has been that some facets of African spiritual patterns withered off while others lost their nationality and linguistic communication and became garbled. Third, the exposure to Christianity led non merely to the transition of Blacks to that faith, but besides to the imbrication of African and Christian beliefs.Free TimeExcept for net inco mes enjoyed by the artisan slaves, most of the slaves depended on obtaining money by selling excess green goodss from their proviso evidences and besides the sale of farm animal that they reared. On Sundays, small town markets were held and the slaves seized the chance to barter or sell their green goods. On these occasions the slaves made purchases of a few pieces of vesture and other points for their places. The Sunday markets were besides occasions when slaves from different plantations were able to socialize and to interchange intelligence and pieces of chitchat. There were besides times of diversion. These were normally at the terminal of the â€Å" harvest † and at Christmas and on public vacations when the slaves were allowed to keep dances which had to stop by midnight.

Oliver Stones Jfk essays

Oliver Stone's Jfk essays Oliver Stone's JFK (1991) is about the assasination of United States president John F. Kennedy as he passed through Dealy Plaza in Dallas Texas on the 22nd of November, 1963. This film seeks to raise concerns that had been building up for some time about the nature of Kennedy's murder. It is a film that seeks to raise a new myth surrounding the assassination that will, in Stone's own words, "interpret history in order to create lasting universal truths...Our film's mythology...hopefully...will replace the Warren Report, as Gone With the Wind replaced Uncle Tom's Cabin, and was in turn replaced by Roots and The Civil War." (pg. 201, The Cinema of Oliver Stone) The Warren reprt is the official investigation that took place regarding Kennedy's murder which concluded that Kennedy was killed by "lone nut" Lee Harvey Oswald who acted alone in the murder and was in turn killed by vigilante Jack Ruby who was also acting alone. Though this is the official conclusion reached in the case it has been suggested that, even before the movie was made "depending on whose poll you quote, between 55 and 75 percent of Americans today believe there was a conspiracy to kill Kennedy." (Dr. Grover B. Proctor, Jr., The Saginaw News, December 21, 1991) That is to say that, after the conclusion was reached by the Warren report, most Americans found it hard to believe that Oswald was acting alone for a number of reasons and came to their own conclusion that he must have been part of a larger plan: a conspiracy. Stone became interested in the conspiracy surrounding the J.F.K. murder when he read Jim Garrison's book On the Trail of the Assassins (1988). Garrison was the District Attourney of New Orleans at the time of Kennedy's murder who, 3 years after the murder actually took place, began to have suspicions that the Warren commision had not found out the entire truth. This led to his becoming obsessed with the case and eventually bringing New Orleans business m...

She Unnames Them by Ursula Le Guin, an Analysis

'She Unnames Them' by Ursula Le Guin, an Analysis Ursula K. Le Guin, a writer predominantly of science fiction and fantasy, was awarded the 2014 National Book Foundation Medal for Distinguished Contribution to American Letters. She Unnames Them, a work of flash fiction, takes its premise from the Biblical book of Genesis, in which Adam names the animals. The story originally appeared in The New Yorker in 1985, where it is available to subscribers.  A free audio version of the author reading her story is also available. Genesis If youre familiar with the Bible, youll know that in Genesis 2:19-20, God creates the animals, and Adam chooses their names: And out of the ground the Lord God formed every beast of the field, and every fowl of the air; and brought them unto Adam to see what he would call them: and whatsoever Adam would call every living creature, that was the name thereof. So Adam gave names to all cattle, to the birds of the air, and to every beast of the field. As Adam sleeps, God takes one of his ribs and forms a companion for Adam, who chooses her name (woman) just as he has chosen names for the animals. Le Guins story reverses the events described here, as Eve unnames the animals one by one. Who Tells the Story? Even though the story is very short, its divided into two separate sections. The first section is a third-person account explaining how the animals react to their unnaming. The second section switches to the first person, and we realize that the story all along has been told by Eve (though the name Eve is never used). In this section, Eve describes the effect of unnaming the animals and narrates her own unnaming.   Whats in a Name? Eve clearly views names as a way to control and categorize others. In returning the names, she rejects the uneven power relations of having Adam in charge of everything and everybody. So, She Unnames Them is a defense of the right to self-determination. As Eve explains to the cats, the issue was precisely one of individual choice. It is also a story about tearing down barriers. Names serve to emphasize the differences between the animals, but without names, their similarities become more evident. Eve explains: They seemed far closer than when their names had stood between myself and them like a clear barrier. Though the story focuses on the animals, Eves own unnaming is ultimately more important. The story is about power relations between men and women. The story rejects not just the names, but also the subservient relationship indicated in Genesis, which portrays women like a smaller part of men, given that they were formed from Adams rib. Consider that Adam declares, She shall be called Woman,/Because she was taken out of Man in Genesis. She Unnames Them Analysis Much of Le Guins language in this story is beautiful and evocative, often evoking the characteristics of the animals as an antidote to simply using their names. For example, she writes: The insects parted with their names in vast clouds and swarms of ephemeral syllables buzzing and stinging and humming and flitting and crawling and tunneling away. In this section, her language almost paints an image of the insects, forcing readers to look closely and think about the insects, how they move, and how they sound. And this is the point where the story ends. The final message is if we choose our words carefully, well have to stop taking it all for granted and really consider the world - and the beings - around us. Once Eve herself considers the world, she must necessarily leave Adam. Self-determination, for her, is more than just choosing her name; its choosing her life.  Ã‚   The fact that Adam doesnt listen to Eve and instead asks her when dinner will be served might seem a little clichà ©d to 21st-century readers. But it still serves to represent the casual thoughtlessness of taking it all for granted that the story, at every level, asks readers to work against. After all, unname isnt even a word, so right from the beginning, Eve has been imagining a world that is unlike the one we know. Sources Genesis 2:19.

Early Childhood Education Essay Example | Topics and Well Written Essays - 1750 words

Early Childhood Education - Essay Example   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Education must begin in early childhood since the values, attitudes, behaviors and skills acquired in this period have a long lasting impact in the future life of children. â€Å"Early childhood education helps to lay a sound intellectual, psychological, emotional, social and physical foundation for development and lifelong learning. It also has enormous potential in fostering values, attitudes, skills and behaviors that support sustainable development e.g. wise use of resources, cultural diversity, gender equality and democracy† (Bell, 2009). Thesis Statement:   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Child Education in the United States is compulsory and it is provided mainly by the public sector. The ages for compulsory education vary from state to state in the US and it usually begins from age four/five and ends at age seventeen/eighteen. Pre-school is the first educational setting for a child. Pre-school education in US commences at an age of four or five and this setting intends to bring out both social and academic outcomes in a child. My thesis statement is that it is during the pre-kindergarten years that a child will discover and explore all the areas of learning and that the education provided in the pre-kindergarten years should be developmentally appropriate in its approach to the curriculum. History:     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   An overview of the history of early childhood education shows that there existed a variation in the ages at which children were sent to school. During the early 1900’s of the US, five or six was the common accepted age for the beginning of formal childhood education at the kindergartens.   Towards the latter half of the twentieth century, an institution named ‘Head Start’ was created to provide education to the poor and the disadvantaged children. This institution provided pre-school training to these children during their ages of three, four or five. It is believed that it was this institution which became a model for the early childhood education.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Project Head Start also was successful in changing the attitude towards young children. Gradually, middle-class Americans began to enroll their children in preschool programs under Project Head Start in order to receive the benefits of early childhood education. This pre-school education was so popular that towards the late 1980’s, there were about 39.1 percent of children aged three and four who received early education.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Though Project Head Start was widely accepted by the Americans, it gradually lost its prominence during the later years. Before Project Head Start, â€Å"infant schools providing education for poor children below the ages of five and six did existed in America, in the early half of the nineteenth century† (Vinovskis, 1993) which were created out of the inspiration from European countries. Infant schools were so popular in 1840’ s that about 40% of three year olds attended school in Massachusetts. But, since this movement was discouraged by the majority of the society, only a fewer number of children under ages four or five were going to the infant schools in Massachusetts.  The infant schools of the nineteenth

Cheyenne Native Americans Research Paper Example | Topics and Well Written Essays - 750 words

Cheyenne Native Americans - Research Paper Example The paper tells that the Cheyenne comprise of two tribes i.e. the Tsà ©tsà ªhà ©stà ¢hese and the Sà ³'taeo'o. Members of the Algonquian family had a common territory (present-day Saskatchewan province) and language.   However, in the mid 16th century, they began their southwestward migration in pursuit of buffaloes and game. However, prior to this, the Cheyenne resided alongside the Missouri River in Minnesota. There is evidence that they were ardent farmers who also made ceramics and artifacts. After losing a battle with the Hidatsa and Mandan tribes, they were driven off to the plains. This is when they took up buffalo hunting and occupied the area that comprises of modern-day Wyoming, Kansas, Colorado, Nebraska and South Dakota. Consequently, their housing units changed from earthen lodges to ‘tipis’, temporary houses made of buffalo hide. This tribe was further subdivided into ten bands and four leaders were appointed from each band. In addition, there was a council of elders that comprised of forty-four elected men. The council convened on a regular basis to deliberate on tribal affairs. Authority was deeply centralized, and the Cheyenne people were united by ritual ceremonialism and the famous ‘Sun Dance’ was the main climax. ‘Sacred arrows’ was another ceremonial ritual and this was undertaken whenever the Cheyenne people waged tribal war. The Cheyenne have a rich cultural heritage which is characterized by religious beliefs, ceremonies, religious practitioners, traditional medicine and veneration of the dead. Aside from the sun dance and arrow dance, there are three other significant ceremonies. These include Mahut renewal, Isiwun and animal dance. Death and life are deemed a spiritual process. A good life automatically results in a good death. Conversely, an evil life leads to malevolent spirits who are bound to torment the living. Hence, the Cheyenne really advocate for a good life. Indian tribes includin g the Cheyenne welcomed the European settlers into America and even taught them survival tactics. Unfortunately, this cordiality was short-lived and the White settlers began to acquire their land. Initially, this was done via treaties but with time the Cheyenne were forcefully evicted from their territories. They were driven off to barren land that was unwanted by the European settlers. As stated above, treaties were the initial means of acquiring Native American territorial land. One famous treaty is the 1851 Laramie Treaty. The Cheyenne were represented in this treaty between US government representatives and Native American tribes. Several resolutions were made and they include the following. First, a truce was reached between warring rival tribes. Secondly, each tribe was to receive $50,000 per annum for 10 years as compensation for their land. Third, the US government gained the right to build infrastructure on native land. The white settlers were also assured of peace when the y traveled along the Overland Trail. Fourth, maps were demarcated to show areas where the tribes were allowed to hunt and fish. Subsequent treaties had well-established reservations for Indian tribes. The mid-seventeenth century was characterized by massive immigration of European settlers into America.

Homicide Investigation Essay Example | Topics and Well Written Essays - 2500 words

Homicide Investigation - Essay Example The corresponding homicide rates, which compare the total number of homicides to population figures, indicate that in 1960 there were 5.1 murders for every 100,000 U.S. citizens. By 1993, the rate had risen to 9.5.1 (Regini). Homicide certainly is a chief social problem in a society where violence is prevalent. The dramatic rate increase enthuse law enforcement efforts to intensify methodical homicide investigation. Traditional techniques reinforced and fortified with technological advancements and modern approaches aim to foster the progress of complex homicide cases. This subject matter appeals to me for the reason that I intend to pursue this line of work upon graduation. It is my conviction that this endeavor is a noble profession that is valuable and significant to society. Although homicide is distressing and tragic in nature, the pursuit of justice for the victims and surviving families is definitely a dignified career. That objective alone establishes a sufficient motivation for me to go through this challenge. Some may view homicide investigation as stressful, demanding and non-lucrative occupation. Nevertheless, there is no better reward than to be regarded as someone of service to the community wherein we and our loved ones are living in. I am aware that being a professional homicide investigator carries with it a great responsibility and requires utmost devotion and determination. It is my aspiration to gain knowledge and expertise in investigative strategies to become a successful homicide investigator. RESEARCH The Law of Homicide has the most complex degree (grading) system of any area in Criminal Law (The Law). In order to properly exercise practical scientific homicide investigation, it is imperative to first be familiar with the definition of homicide itself. Primitive legal codes defined homicide as taking the life of a human being and included suicide. As the legal system evolved, suicide was excluded and homicide became "the killing of one person by another." (Allen and Simonsen 1998, p. 615). Generally, if a person is accountable for the death of another person, that is classified as homicide. There was even a controversy whether abortion can be deemed as homicide: The differentiation between abortion and homicide has not always been so clear-cut. Some people consider a fetus to be a human being from the moment of conception, whereas others are more liberal in their beliefs. The debate over the line between human being and nonhuman being, with regard to abortion, is a continuous issue, but the U.S. Supreme Court's January 1973 Roe v. Wade decision eliminated the act, especially in the first trimester of pregnancy, from the definition of homicide. At the start of the twenty-first century, forty states and the District of Columbia prohibited (except in rare circumstances) abortions after the fetus becomes viable (i.e., capable of surviving outside the mother on its own)-generally after the twenty-seventh

Religion As A Means For Political And Economic Gains Essay

Religion As A Means For Political And Economic Gains - Essay Example This statement will be tested through qualitative analysis of the existing literature on religion and a case study of Taliban. By looking into the question of whether Pakistan used Islam through Talibanization of Afghanistan essentially to stem the growing Pashtun nationalist movement, I will attempt to show that religion was used for political gains and virtually economic gains by a country which broke apart at the hands of a similar nationalist movement three decades ago. The outcome of this research can help to bring us closer to understanding religion and add to an ongoing debate on religion and its correlation with politics and economy. Keywords: religion, religious exploitation, religious values, fundamentalism, Taliban, Afghanistan, Pakistan, Pashtunistan Research Design in Anthropology (Final Project) 1. OBJECT The main function of religion is maintaining a desirable social order which protects the individuals and the society from physical and emotional harm caused by fellow members and "promises deliverance from deprivation" (Columbia Encyclopedia), but since it has the ability to gain a high level of acceptability among its followers, sometimes to the level of reverence, it demands a blind faith from who follow the rituals without reasoning. In their introduction to the first volume of the famed "Fundamentalism Project, " Fundamentalisms Observed, editors Martin Marty and R. Scott Appleby (1991) claim that the religious aspect of fundamentalism tends to express itself in the following four ways: as a "fighting for" the worldview associated with the religion; a "fighting with" the myths, traditions and doctrines created by the religion; a "fighting against" those who do not subscribe to the religion; and finally, a "fighting under" the god or other transcendent reference thought to be the religion's ultimate source. In under-developed societies religion has a stronger hold over the poor and the powerless who seek protection in its name and solace when they when they fail to achieve the desired goals in life. Since the clergy claim ownership of religion their role becomes the most important for the society as well as for the individual, sometimes even more important than God himself. Some high-priests become so powerful that their ascendancy rivals the powers of the rulers and other pressure groups. Thus religion commands absolute obedience from the poor and the powerless which enslaves them to the custodians of religion namely the clergy which in turn gives them the power to alter social behavior. More recently, such a phenomenon has come to be identified as "fundamentalism" whereby the clergy and associates have sought or achieved change of social, political and economic nature. "Any socio-political movement that requires of its members a strict adherence to specifi ed "fundamentals" or doctrines; that seeks to impose those fundamentals, by persuasion or force, on any who are outside the movement; and that claims for its motivation in doing so a divine, or otherwise transcendentally grounded, mandate." (Carr & Saha, 2001) This has happened in some societies while elsewhere other social factors emerged to mollify or cancel the magic of the religion and its custodians such as interfaith or sectarian rivalry, rise of progressive forces which further the power of reasoning and science and so on. History is full of incidents where clergy using religious edicts and faith have tried to alter social

(Emergency Management) 2001 D.C.Sniper - Case Study Example John Allen Muhammad was the man behind the sniper attacks, carrying out the shootings from his modified vehicle. Muhammad had an accomplice by the name Lee Boyd Malvo (Mehrotra, 2006). A number of preliminary shootings had taken place before the killer moved to Washington area. Several people were killed and several injured, surviving bullet wounds after being shot from a distance. A number of sniper attacks took place in Washington area, with some victims surviving while others died. These attacks followed the September 11 terrorist attacks in New York. On the second day of October, 2002, a gunshot was fired into a craft store that was owned by a man called Michael at around 5:20 pm. In this incident, fortunately, no one was injured in the incident. There had been previous attacks in Alabama, Los Angeles, Maryland, Virginia and Washington D.C, but this incident was not quickly connected to them (Turvey, 2011). The Aspen Hill incident marked the beginning of a trail of incidents in the Washington D.C area. On the same day that the Aspen Hill incident occurred, James Martin was shot dead at around 6:30 pm. Martin was shot at a grocery store’s parking lot in Wheaton. James Buchanan became a victim of the shooter on the 3rd of October, 2002. The incident took place at Rockville Pike, when the victim was mowing grass. On the same day, Premkumar Walekar succumbed to gunshot wounds in Aspen Hill when he was refueling his car. The incident took place at around 8:12 am. The 3rd of October, 2002 also saw the death and injury of several people at different times of the day. Sarah Ramos died at 8: 37 am after she was shot in Rossmoor Boulevard, seated on a sidewalk bench reading a book. At 9:58 am, Lori Ann was killed at a gas station in Kensington, Maryland. This marked the end of the morning trail of killings, but the day was yet to realize more killings later. Pascal Charlot was shot later that day in Georgia Avenue at around 9:15 pm. He barely

(Carr & Saha, 2001) This has happened in some societies while elsewhere other social factors emerged to mollify or cancel the magic of the religion and its custodians such as interfaith or sectarian rivalry, rise of progressive forces which further the power of reasoning and science and so on. History is full of incidents where clergy using religious edicts and faith have tried to alter social

Should Students Be Required to Take a Second Language Course Essay Example for Free

Should Students Be Required to Take a Second Language Course Essay A spectacle is happening in today’s society that the world, one hundred years ago, could have never thought possible. Cultural barriers between countries are blurring and are eventually predicted to disappear entirely, forming one, global nation. This process of globalization is due mainly to the rise of modern technologies through the internet and computers. Just a few decades ago, people would have never thought that an international business meeting would be as simple as few clicks of a mouse and a video-call. Now, international trading, as well as many other tasks, is becoming a reality. However, the only thing that might restrain a deal between a start-up American business and a possible Chinese investor is an acute language barrier. To keep the machine that is the global market well-oiled and functioning at maximum efficiency, it only makes sense for a common language to be spoken. The sooner the United States schools realize this, the sooner they can stay competitive on a global scale. The culture-blending effects of globalization necessitate high school and college students to achieve proficiency in a second, useful language. To fully understand why a second language is so important for United States citizens, one must understand the causes of constantly rising globalization. The first and most obvious cause is the internet and the lines of communication that it opens. If used appropriately, the internet can connect people from a variety of nationalities for almost endless purposes. Perhaps the most appealing purpose would be the potential for international business endeavors. Businessmen have, since the dawn of the internet, seized the opportunity to use it for global business growth. They recognize that the internet is an information highway that can be used to help business contact clients from around the globe as well as promote their business on the web. These business opportunities have given once developmentally backwards nations such as China or India, the ability to contact other well-developed countries for trade. This causes and influx in these countries economies as well as giving the developed counties new trading partners that may have higher potential manufacturing power than they do (Globalization and Localization Association Predicts Jump in Demand for Language Industry Services). With all of these benefits for the global economy, it is not hard to see why these countries have welcomed globalization. Money is not the only thing that is being transferred in today’s global economy. Like a pilot fish on a shark, the sharing of cultures comes along with globalization. Since the world is so connected now through technology and trade, many cultures are being mixed together in a global melting pot. This exposes a need for a common language to be spoken between nations. Since language can be crucial to understanding a country’s culture as well as communicating with the citizens of the country, businesses often look for potential employees who are bilingual because they have that advantage over people who are not (Akay). Therefore, if a person learns a second language they can gain an edge in the job market. A second language is key for the modern businessman due to the rise of globalization. Schools around the world realize that language is a necessity for modern workers to be competitive and are adjusting their curriculum to meet these modern needs. For instance, in foreign countries, it is a common practice to first learn their native language and then after that, to take English classes since it is currently recognized as an international language. This puts them at a distinct advantage over people who do not speak multiple languages since they can participate in national as well as international affairs (Akay). The United States is a different story. There is an acute lack of emphasis on language in American schools, and the languages that they do teach (typically French, German, and Spanish) are rarely used after the student graduates. These languages, however, are not as important as they were at one time. Other languages should be taught as another option for students. Since China is the United States’ primary trading partner, it makes sense for students to have the option to learn Mandarin (Lapowsky). Languages spoken in other major trading countries such as India should be taught as well. These courses should be required for students to take so that America can share a common language with these countries as well as stay competitive on a global scale. Globalization is creating a world where learning a second language is a modern must. Language can open new doors for people, and now that cultural barriers are eroding, new languages have become more important and useful than ever before. To ensure that their students can grasp every opportunity that comes their way, schools need to require students to achieve proficiency in a second language. Since globalization is showing no signs of slowing, American Students need to buckle up and embrace the ride.

MapReduce for Distributed Computing

MapReduce for Distributed Computing 1.) Introduction A distributed computing system can be defined as a collection of processors interconnected by a communication network such that each processor has its own local memory. The communication between any two or more processors of the system takes place by passing information over the communication network. It has its application in various fields like Hadoop and Map Reduce which we will be discussing further in details. Hadoop is becoming the technology of choice for enterprises that need to effectively collect, store and process large amounts of structured and complex data. The purpose of the thesis is to research about the possibility of using a MapReduce framework to implement Hadoop. Now all this is possible by the file system that is used by Hadoop and it is HDFS or Hadoop Distributed File System. HDFS is a distributed file system and capable to run on hardware. It is similar with existing distributed file systems and its main advantage over the other distributed File system is, it is designed to be deployed on low-cost hardware and highly fault-tolerant. HDFS provides extreme throughput access to applications having large data sets. Originally it was built as infrastructure support for the Apache Nutch web search engine. Applications that run using HDFS have extremely large data sets like few gigabytes to even terabytes in size. Thus, HDFS is designed to support very large sized files. It provides high data communication and can connect hundreds of nodes in a single cluster and supports tens of millions of files in a system at a time. Now we take all the above things mentioned above in details. We will be discussing various fields where Hadoop is being implemented like in storage facility of Facebook and twitter, HIVE, PIG etc. 2.) Serial vs. Parallel Programming In the early decades of computing, programs were serial or sequential, that is, a program consisted of a categorization of instructions, where each instruction executed sequential as name suggests. It ran from start to finish on a single processor. Parallel programming (grid computing) developed as a means of improving performance and efficiency. In a parallel program, the process is broken up into several parts, each of which will be executed concurrently. The instructions from each part run simultaneously on different CPUs. These CPUs can exist on a single machine, or they can be CPUs in a set of computers connected via a network. Not only are parallel programs faster, they can also be used to solve problems on large datasets using non-local resources. When you have a set of computers connected on a network, you have a vast pool of CPUs, and you often have the ability to read and write very large files (assuming a distributed file system is also in place). Parallelism is nothing but a strategy for performing complex and large tasks faster than traditional serial way. A large task can either be performed serially, one step following another, or can be decomposed into smaller tasks to be performed simultaneously using concurrent mechanism in parallel systems. Parallelism is done by: Breaking up the process into smaller processes Assigning the smaller processes to multiple processors to work on simultaneously Coordinating the processors Parallel problem solving can be seen in real life application too. Examples: automobile manufacturing plant; operating a large organization; building construction; 3.) History of clusters: Clustering is the use of cluster of computers, typically PCs or some workstations, storage devices, and interconnections, appears to outsider (user) as a single highly super system. Cluster computing can be used for high availability and load balancing. It can be used as a relatively low-cost form of parallel processing system for scientific and other related applications. Computer clustering technology put cluster of few systems together to provide better system reliability. Cluster server systems can connect a group of systems together in order to provide combined processing service for the clients in the cluster. Cluster operating systems distribute the tasks amongst the available systems. Clusters of systems or workstations can connect a group of systems together to share critically demanding and tough tasks. Theoretically, a cluster operating system can provide seamless optimization in every case. At the present time, cluster server and workstation systems are mostly used in High Availability applications and in scientific applications such as numerical computations. A cluster is a type of parallel or distributed system that: consists of a collection of interconnected whole computers and is used as single, unified computing resource. The whole computer in above definition can have one or more processors built into a single operating system image. Why a Cluster Lower cost: In all-purpose small sized systems profit from using proper technology. Both hardware and software costs tend to be expressively minor for minor systems. However one must study the entire cost of proprietorship of your computing environment while making a buying conclusion. Next subdivision facts to some issues which may counterbalance some of the gains of primary cost of acquirement of a cluster. . Vendor independence: Though it is usually suitable to use similar components through a number of servers in a cluster, it is worthy to retain a certain degree of vendor independence, especially if the cluster is being organized for long term usage. A Linux cluster created on mostly service hardware permits for much better vendor liberation than a large multi-processor scheme using a proprietary operating system. Scalability: In several environments the problem load is too large that it just cannot be processed on a specific system within the time limits of the organization. Clusters similarly provide a hassle-free path for increasing the computational means as the load rises over time. Most large systems scale to a assured number of processors and require a costly upgrade Reliability, Availability and Serviceability (RAS): A larger system is typically more vulnerable to failure than a smaller system. A major hardware or software component failure fetches the whole system down. Hence if a large single system is positioned as the computational resource, a module failure will bring down substantial computing power. In case of a cluster, a single module failure only affects a small part of the overall computational resources. A system in the cluster can be repaired without bringing rest of the cluster down. Also, additional computational resources can be added to a cluster while it is running the user assignment. Hence a cluster maintains steadiness of user operations in both of these cases. In similar type of situations a SMP system will require a complete shutdown and a restart. Adaptability: It is much easier to adapt the topology. The patterns of linking the compute nodes together, of a cluster to best suit the application requirements of a computer center. Vendors typically support much classified topologies of MPPs because of design, or sometimes testing, issues. Faster technology innovation: Clusters benefit from thousands of researchers all around the world, who typically work on smaller systems rather than luxurious high end systems. Limitations of Clusters It is noteworthy to reference certain shortcomings of using clusters as opposite to a single large system. These should be closely cautious while defining the best computational resource for the organization. System managers and programmers of the organization should intensely take part in estimating the following trade-offs. A cluster increases the number of individual components in a computer center. Every server in a cluster has its own sovereign network ports, power supplies, etc. The increased number of components and cables going across servers in a cluster partially counterbalances some of the RAS advantages stated above. It is easier to achieve a single system as opposed to numerous servers in a cluster. There are a lot more system services obtainable to manage computing means within a single system than those which can assistance manage a cluster. As clusters progressively find their way into profitable organizations, more cluster savvy tools will become accessible over time, which will bridge some of this gap. In order for a cluster to scale to make actual use of numerous CPUs, the workload needs to be properly well-adjusted on the cluster. Workload inequity is easier to handle in a shared memory environment, because switching tasks across processors doesnt involve too much data movement. On the other hand, on a cluster it tends to be very tough to move a by this time running task from one node to another. If the environment is such that workload balance cannot be controlled, a cluster may not provide good parallel proficiency. Programming patterns used on a cluster are typically diverse from those used on shared-memory systems. It is relatively easier to use parallelism in a shared-memory system, since the shared data is gladly available. On a cluster, as in an MPP system, either the programmer or the compiler has to explicitly transport data from one node to another. Before deploying a cluster as a key resource in your environment, you should make sure that your system administrators and programmers are comfortable in working in a cluster environment. Getting Started With Linux Cluster: Although clustering can be performed on various operating systems like Windows, Macintosh, Solaris etc. , Linux has its own advantages which are as follows:- Linux runs on a wide range of hardware Linux is exceptionally stable Linux source code is freely distributed. Linux is relatively virus free. Having a wide variety of tools and applications for free. Good environment for developing cluster infrastructure. Cluster Overview and Terminology A compute cluster comprises of a lot of different hardware and software modules with complex interfaces between various modules. In fig 1.3 we show a simplified concept of the key layers that form a cluster. Following sections give a brief overview of these layers. 4.) Parallel computing and Distributed Computing system Parallel computing It is the concurrent execution of some permutation of multiple instances of programmed instructions and data on multiple processors in order to achieve results faster. A parallel computing system is a system in which computer with more than one processor for parallel processing. In the past, each processor of a multiprocessing system every time came in its own processor packaging, but in recent times-introduced multicore processors contain multiple logical processors in a single package. There are many diverse kinds of parallel computers. They are well-known by the kind of interconnection among the processors (â€Å"processing elements or PEs) and memory. Distributed Computing System: There are two types of distributed Computing systems: Tightly coupled system: In these systems, there is a single system wide primary memory (address space) that is shared by all the processors. In these systems any communication between the processors usually takes place through the shared memory. In tightly coupled systems, the number of processors that can be usefully deployed is usually small and limited by the bandwidth of the shared memory. Tightly coupled systems are referred to as parallel processing systems Loosely coupled systems: In these systems, the processors do not share memory, and each processor has its own local memory. In these systems, all physical communication between the processors is done by passing messages across the network that interconnects the processors. In this type of System Processors are expandable and can have unlimited number of processor. Loosely coupled systems, are referred to as distributed computing systems. Various Models are used for building Distributed Computing System: 4.1) Minicomputer Model It is a simple extension of the centralized time-sharing system. A distributed computing system based on this classical consists of a few minicomputers or large supercomputers unified by a communication network. Each minicomputer usually has many user simultaneously logged on to it through several terminals linked to it with every user logged on to one exact minicomputer, with remote access to other minicomputers, The network permits a user to access remote resources that are available on same machine other than the one on to which the user is currently logged. The minicomputer model is used when resource sharing with remote users is anticipated. The initial ARPAnet is an example of a distributed computing system based on the minicomputer model. 4.2) Workstation Model Workstation model consists of several workstations unified by a communication network. The best example of a Workstation Model can be a company’s office or a university department which may have quite a few workstation scattered throughout a building or campus, with each workstation equipped with its individual disk and serving time which is specifically during the night, Notion of using workstation Model is that when certain workstations are idle (not being used), resulting in the waste of great amounts of CPU time the model connects all these workstations by a high-speed LAN so that futile workstations may be used to process jobs of users who are logged onto to other workstations and do not have adequate processing power at their own workstations to get their jobs handled efficiently. A user logs onto one of the workstations which is his â€Å"home† workstation and submits jobs for execution if the system does not have sufficient processing power for executing the processes of the submitted jobs resourcefully, it transfers one or more of the processes from the user’s workstation to some other workstation that is currently ideal and gets the process executed there, and finally the outcome of execution is given back to the user’s workstation deprived of the user being aware of it. The main Issue increases if a user logs onto a workstation that was idle until now and was being used to perform a process of another workstation .How the remote process is to be controlled at this time .To handle this type of problem we have three solutions: The first method is to allow the remote process share the resources of the workstation along with its own logged-on user’s processes. This method is easy to apply, but it setbacks the main idea of workstations helping as personal computers, because if remote processes are permitted to execute concurrently with the logged-on user’s own processes, the logged-on user does not get his or her fail-safe response. The second method is to kill the remote process. The main disadvantage of this technique is that all the processing done for the remote process gets lost and the file system may be left in an erratic state, making this method repellent. The third method is to migrating the remote process back to its home workstation, so that its execution can be continued there. This method is tough to implement because it involves the system to support preemptive process migration facility that is stopping the current process when a higher priority process comes into the execution. Thus we can say that the workstation model is a network of individual workstations, each with its own disk and a local file system. The Sprite system and experimental system developed at Zerox PARC are two examples of distributed computing systems, based on the workstation model. 4.3) Workstation-Server Model Workstation Server Model consists of a limited minicomputers and numerous workstations (both diskful and diskless workstations) but most of them are diskless connected by a high speed communication Network. A workstation with its own local disk is generally called a diskful workstation and a workstation without a local disk is named as diskless workstation. The file systems used by these workstations is either applied either by a diskful workstation or by a minicomputer armed with a disk for file storage. One or more of the minicomputers are used for applying the file system. Other minicomputer may be used for providing other types of service area, such as database service and print service. Thus, every minicomputer is used as a server machine to provide one or more types of services. Therefore in the workstation-server model, in addition to the workstations, there are dedicated machines (may be specialized workstations) for running server processes (called servers) for handling and providing access to shared resources. A user logs onto a workstation called his home workstation, Normal computation activities required by the user’s processes are performed at the user’s home workstation, but requirements for services provided by special servers such as a file server or a database server are sent to a server providing that type of service that performs the user’s requested activity and returns the result of request processing to the user’s workstation. Therefore, in this model, the user’s processes need not be migrated to the server machines for getting the work done by those machines. For better complete system performance, the local disk of diskful workstation is normally used for such purposes as storage of temporary file, storage of unshared files, storage of shared files that are rarely changed, paging activity in virtual-memory management, and caching of remotely accessed data. Workstation Server Model is better than Workstation Model in the following ways: It is much cheaper to use a few minicomputers equipped with large, fast disks than a large number of diskful workstations, with each workstation having a small, slow disk. Diskless workstations are also preferred to diskful workstations from a system maintenance point of view. Backup and hardware maintenance are easier to perform with a few large disks than with many small disks scattered all Furthermore, installing new releases of software (such as a file server with new functionalities) is easier when the software is to be installed on a few file server machines than on every workstations. In the workstation-server model, since all files are managed by the file servers, users have the flexibility to use any workstation and access the files in the same manner irrespective of which workstation the user is currently logged on .Whereas this is not true with the workstation model, in which each workstation has its local file system, because different mechanisms are needed to access local and remote files. Unlike the workstation model, this model does not need a process migration facility, which is difficult to implement. In this model, a client process or workstation sends a request to a server process or a mini computer for getting some service such as reading a block of a file. The server executes the request and sends back a reply to the client that contains the result of request processing. A user has guarantied response time because workstations are not used for executing remote process. However, the model does not utilize the processing capability of idle workstation. The V-System (Cheriton 1988) is an example of a distributed computing system that is based on the workstation-server model. 4.4) Processor-Pool Model In the process of pool model the processors are pooled together-to be shared by the users needed. The pool -or processors consist of a large number of micro-computers and minicomputers attached to the network. Each processor in the pool has its own memory to load and run a system program or an application program of the distributed-computing system. The processor-pool model is used for the purpose that most of the time a user does not need any computing power but once in a while he may need a very large amount of computing power for short time (e.g., when recompiling a program consisting of a large number of files after changing a basic shared declaration). In processor-pool model, the processors in the pool have no terminal attached directly to them, and users access the system from terminals that are attached to the network via special devices. These terminals are either small diskless workstations or graphic terminals. A special server called a run server manages and allocates the processors in the pool to different users on a demand basis. When a user submits a job for computation an appropriate number of Processors are temporarily assigned to his or her job by the run server. In this type of model we do not have a concept of home machine, in this when a user logs on he is logged on to the whole system by default. The processor-pool model allows better utilization of the available processing power of a distributed computing system as in this model the entire processing power of the system is available for use by the current logged-on users, whereas this is not true for the workstation-server model in which several workstations may be idle at a particular time but they cannot be used for processing the jobs of other users. Furthermore, the processor-pool model provides greater flexibility than the workstation-server model as the system’s services can be easily expanded without the need to install any more computers. The processors in the pool can be allocated to act as extra servers to carry any additional load arising from an increased user population or to provide new services. However, the processor-pool model is usually considered to be unsuitable for high-performance interactive application, program of a user is being executed and the terminal via which the user is interacting with the system. The workstation-server model is generally considered to be more suitable for such applications. Amoeba [Mullender et al. 1990]. Plan 9 [Pike et al. 1990], and the Cambridge Distributed Computing System [Needham and Herbert 1982] are examples of distributed computing systems based on the processor-pool model. 5) ISSUES IN DESIGNING A DISTRIBUTED OPERATING SYSTEM To design a distributed operating system is a more difficult task than designing a centralized operating system for several reasons. In the design of a centralized operating system, it is assumed that the operating system has access to complete and accurate information about the environment is which it is functioning. In a distributed system, the resources are physically separated, their is no common clock among the multiple processors as the delivery of messages is delayed, and not have up-to-date, consistent knowledge about the state of the various components of the underlying distributed system .And lack of up-to-date and consistent information makes many thing (such as management of resources and synchronization of cooperating activities) much harder in the design of a distributed operating system,. For example, it is hard to schedule the processors optimally if the operating system is not sure how many of them are up at the moment. Therefore a distributed operating system must be designed to provide all the advantages of a distributed system to its users. That is, the users should be able to view a distributed system as a virtual centralized system that is flexible, efficient, reliable, secure, and easy to use. To meet this challenge, designers of a distributed operating system must deal with several design issues. Some of the key design issues are: 5.1) Transparency The main goal of a distributed operating system is to make the existence of multiple computers invisible (transparent) and that is to provide each user the feeling that he is the only user working on the system. That is, distributed operating system must be designed in such a way that a collection of distinct machines connected by a communication subsystem appears to its users as a virtual unprocessed. Accesses Transparency: Access transparency typically refers to the situation where users should not need or be able to recognize whether a resource (hardware or software) is remote or local. This implies that the distributed operating system should allow users to access remote resource in the same ways as local resources. That is, the user should not be able to distinguish between local and remote resources, and it should be the responsibility of the distributed operating system to locate the resources and to arrange for servicing user requests in a user-transparent manner. Location Transparency: Location Transparency is achieved if the name of a resource is kept hidden and user mobility is there, that is: Name transparency: This refers to the fact that the name of a resource (hardware or software) should not reveal any hint as to the physical location of the resource. Furthermore, such resources, which are capable of being moved from one node to another in a distributed system (such as a file), must be allowed to move without having their names changed. Therefore, resource names must be unique system wide. User Mobility: this refers to the fact that no matter which machine a user is logged onto, he should be able to access a resource with the same name he should not require two different names to access the same resource from two different nodes of the system. In a distributed system that supports user mobility, users can freely log on to any machine in the system and access any resource without making any extra effort. Replication Transparency Replicas or copies of files and other resources are created by the system for the better performance and reliability of the data in case of any loss. These replicas are placed on the different nodes of the distributed System. Both, the existence of multiple copies of a replicated resource and the replication activity should be transparent to the users. Two important issues related to replication transparency are naming of replicas and replication control. It is the responsibility of the system to name the various copies of a resource and to map a user-supplied name of the resource to an appropriate replica of the resource. Furthermore, replication control decisions such as how many copies of resource should be created, where should each copy be placed, and when should a copy be created/deleted should be made entirely automatically by the system in a user -transparent manner. Failure Transparency Failure transparency deals with masking from the users partial failures in the system, Such as a communication link failure, a machine failure, or a storage device crash. A distributed operating system having failure transparency property will continue to function, perhaps in a degraded form, in the face of partial failures. For example suppose the file service of a distributed operating system is to be made failure transparent. This can be done by implementing it as a group of file servers that closely cooperate with each other to manage the files of the system and that function in such a manner that the users can utilize the file service even if only one of the file servers is up and working. In this case, the users cannot notice the failure of one or more file servers, except for slower performance of file access operations. Be implemented in this way for failure transparency. An attempt to design a completely failure-transparent distributed system will result in a very slow and highly expensive system due to the large amount of redundancy required for tolerating al l types of failures. Migration Transparency An object is migrated from one node to another for a better performance, reliability and great security. The aim of migration transparency is to ensure that the movement of the object is handled automatically by the system in a user-transparent manner. Three important issues in achieving this goal are as follows: Migration decisions such as which object is to be moved from where to where should be made automatically by the system. Migration of an object from one node to another should not require any change in its name. When the migrating object is a process, the interposes communication mechanism should ensure that a massage sent to the migrating process reaches it without the need for the sender process to resend it if the receiver process moves to another node before the massage is received. Concurrency Transparency In a distributed system multiple users uses the system concurrently. In such a situation, it is economical to share the system resource (hardware or software) among the concurrently executing user processes. However since the number of available resources in a computing system is restricted one user processes, must necessarily influence the action of other concurrently executing processes. For example, concurrent update to the file by two different processes should be prevented. Concurrency transparency means that each user has a feeling that he is the sole user of the system and other users do not exist in the system. For providing concurrency transparency, the recourse sharing mechanisms of the distributed operating system must have the following properties: An event-ordering property ensures that all access requests to various system resources are properly ordered to provide a consistent view to all users of the system. A mutual-exclusion property ensures that at any time at most one process accesses a shared resource, which must not be used simultaneously by multiple processes if program operation is to be correct. A no-starvation property ensures that if every process that is granted a resources which must not be used simultaneously by multiple processes, eventually releases it, every request for that restore is eventually granted. A no-deadlock property ensures that a situation will never occur in which competing process prevent their mutual progress ever though no single one requests more resources than available in the system. Performance Transparency The aim of performance transparency is never get
