13 Expository Essay Topics on Drug Use and Its Consequences

13 Expository Essay Topics on Drug Use and Its Consequences If you are writing an essay on drug use and its consequences, you might be in need of facts. Below are some facts that can help you support your claims: Both psychology and sociology seek to explain drug abuse, and each has their distinct perspective on the subject. The phrase ‘drug abuse’ implies excessive use of a controlled substance, resulting in negative consequences. While sociology emphasizes the possible influence of environmental, cultural and social aspects on drug abuse, psychology seeks to establish factors that exist in a person’s sub-conscious mind as influencing drug abuse. In fact, psychological and sociological factors may account for the prevalence of drug abuse. Defining drug abuse must acknowledge social context. Negative behaviour is connoted by the term ‘drug abuse,’ according to an article from DrugLibrary.org. However, sociology views behaviour as being positive or negative based on the social context of such behaviour. The same behaviour could take on a negative or positive hue, depending on the social circumstances. There are various sociological factors – such as the socio-economic status of a person that could influence drug abuse. For instance, having to cope with adverse environmental or social conditions could drive a person to abuse drugs. A drug abuser might be encouraged by mass media or his/ her peer group, either of which might in some manner validate his behaviour. The psychological perspective explaining the causes of drug abuse focuses on a drug abuser’s inner motivations rather than his/ her social circumstances. Psychology does not allow for the possibility that a drug abuser might deliberately opt to abuse drugs, even to the extent that his/ her behaviour could result in ruining their personal relationships or financial stability. The drug abuser’s behaviour could also lead to their imprisonment, hardly a desirable option. Instead the psychological perspective stresses that the drug abuser behaves as they do because of a biological predisposition to an addiction that is beyond their control. According to the website of the California State University at Northridge, drug abuse is attributable to several environmental and cultural factors that, however, fail to account for all instances of drug abuse. Psychology discounts sociology’s ability to provide an adequate explanation as to why even under similar environmental, social, and cultural circumstances, some people abuse drugs while others don’t. Social interaction among humans is also affected by drug abuse and can have a radical effect on your child’s relations with friends, family members and others. The entire family of a drug-abusing youth is affected psychologically, financially and emotionally. Teenage drug users tend to distant themselves from members of their family as well as from activities involving such family members. Additionally, they set a poor example for younger siblings. Drug use impairs their decision-making ability and judgment, thereby inducing hostility towards their family members and even causing them to steal money from their family members to buy drugs. There is an observed decline in the academic performance of teen drug abusers, who also reveal a greater propensity to absenting themselves from school and related activities. A higher drop-out rate has also been found among drug abusers, according to relevant research. Cognitive and behavioural problems may also interfere with the academic performance of youth who use alcohol and drugs. The academic performance of youth engaging in drug and alcohol abuse is also impacted by behavioural and cognitive problems concomitant with such substance abuse. Teenage drug abusers tend to alienate themselves from peers, and the related stigma is accompanied by the youth’s disengagement from community events and school. Teens who eschew drug use are best advised to keep a healthy distance from those who use drugs. As endorsed by experts, such youth are more likely to become drug users themselves if they associate with drug abusing peers and are exposed to the latter’s delinquent behaviour. There is a perceived correlation between substance abuse and delinquency. Quite often, drug-abusing youth face consequences such as arrest and adjudication, in which case the juvenile justice system intervenes. While a clear causal relationship between substance abuse and delinquency cannot be established or for that matter, even a causal relationship between delinquency and alcohol and drug use there is no denying the fact that the two behaviours are linked. Such linkage between substance abuse and delinquency often leads to youths associating with negative peer groups, in addition to problems in the youth’s domestic and academic environments. Drugs can have a negative and harmful effect on a person’s perception, concentration and motor functions, making drugged driving a major cause for concern. Driving under the influence of drugs can cause potential harm to the driver as well as others, owing to the increased possibility of accidents. For instance, a driver’s mental faculties, under the influence of Marijuana, can stay impaired for as long as three hours after ingesting the drug, which can stay in the driver’s system for as long as 24 hours. Roughly 15% of teen drug users (or one in six such individuals) have confessed to driving under the influence. Behaviour patterns of teens influenced by drug abuse also make them vulnerable to sexually transmitted diseases such as HIV/AIDS. This may be due to injecting drugs and sharing used needles. Alternatively, it could result from lack of judgment or controlled impulse while under the influence of drugs with mood-altering properties. This in turn would increase the possibility of engaging in sexual behaviour involving greater exposure to risk. Psychosocial dysfunctions such as withdrawal, apathy, developmental lags, and depression are among the mental health problems most commonly associated with adolescent substance abuse. Youth who abuse substances are more likely than youth who desist from drug use to fall prey to mental problems. These include suicidal thoughts that can lead to suicide or attempted suicide, apart from other mental health problems such as personality disorders, conduct problems, and depression. For instance, interference with psychomotor skills, learning, and short-term memory are mental health problems commonly associated with Marijuana use. The possibility drug addiction is never considered by somebody who uses them for the first time. However, almost invariably addiction is a consequence of using drugs that have a habit-forming quality. Addiction leads in turn to loss of judgement and control; stopping use of the drug can cause severe physical and psychological symptoms. These could manifest as stress, unhappiness, irritability and anxiety, among other symptoms. Some drugs could also induce withdrawal symptoms such as bone pain, diarrhoea, flu, tremors and, in rare instances, seizures. The brain function of long-term users of drugs can change pervasively. For instance, long-term use of Ecstasy can result in sleep disorders, anxiety, depression, and memory deficits. It is quite a serious issue to write on. That’s why it’s necessary to use only truthful information. Apply these facts along with the suggested topics on drug use and its consequences to outline a high quality text.

About the U.S. House of Representatives

About the U.S. House of Representatives The United States is a large, fractured, diverse and yet still unified nation, and few government bodies reflect the paradox that is this country better than the House of Representatives. Key Takeaways: U.S. House of Representatives The House of Representatives is the lower chamber of the two legislative bodies in the United States federal government.The House is currently made up of 435 representatives- referred to as congressmen or congresswomen- who serve an unlimited number of two-year terms. The number of representatives from each state is based on the state’s population.As required by the Constitution, representatives must reside in the state from which they are elected, must have been a U.S. citizen for at least seven years, and be at least 25 years old.A representative’s primary duties include introducing, debating, and voting on bills, proposing amendments to bills, and serving on committees.The House has the exclusive powers to initiate all tax and spending bills and to impeach federal officials.   Metrics of the House The House is the lower of the two legislative bodies in the U.S. government. It has 435 members, with the number of representatives per state dependent upon that states population. House members serve two-year terms. Rather than represent their entire state, as Senate members do, they represent a specific district. This tends to give House members a closer link to their constituents-and more accountability, since they have but two years to satisfy voters before having to run for re-election. Also referred to as a congressman or congresswoman, a representative’s primary duties include introducing bills and resolutions, offering amendments and serving on committees.   Alaska, North Dakota, South Dakota, Montana and Wyoming, all sprawling but sparsely populated states, have just one representative each in the House; tiny states like Delaware and Vermont also send just one representative to the House. By contrast, California sends 53 representatives; Texas sends 32; New York sends 29, and Florida sends 25 representatives to Capitol Hill. The number of representatives each state is allotted is determined every 10 years in accordance with the federal census. Although the number has changed periodically through the years, the House has remained at 435 members since 1913, with shifts in representation occurring among different states. The system of House representation based on district population was part of the Great Compromise of the Constitutional Convention in 1787, which led to the Permanent Seat of Government Act establishing the nations federal capital in Washington, DC. The House assembled for the first time in New York in 1789, moved to Philadelphia in 1790 and then to Washington, DC, in 1800. The Powers of the House While the Senates more exclusive membership may make it seem the more powerful of the two chambers of Congress, the House is charged with a vital task: the power to raise revenue through taxes. The House of Representatives also has the power of impeachment, in which a sitting president, vice president or other civil officials such as judges may be removed for high crimes and misdemeanors, as enumerated in the Constitution. The House is solely responsible for calling for impeachment. Once it decides to do so, the Senate tries that official to determine whether he or she should be convicted, which means automatic removal from office. Leading the House House leadership rests with the speaker of the house, usually a senior member of the majority party. The speaker applies House rules and refers bills to specific House committees for review. The speaker is also third in line to the presidency, after the vice president. Other leadership positions include the majority and minority leaders who monitor legislative activity on the floor, and the majority and minority whips who ensure that House members vote according to their respective parties positions. The  House Committee System The House is divided into committees in order to tackle the complex and various matters on which it legislates. House committees study bills and hold public hearings, gathering expert testimony and listening to voters. If a committee approves a bill, it then puts it before the entire House for debate. House committees have changed and evolved over time. Current committees include those on: agriculture;appropriations;armed services;the budget, education, and labor;energy and commerce;financial services;foreign affairs;homeland security;House administration;judiciary;natural resources;oversight and government reform;rules;science and technology;small business;standards of official conduct;transportation and infrastructure;veterans affairs; andways and means. In addition, House members may serve on joint committees with Senate members. The Raucous Chamber Given the shorter terms of House members, their relative proximity to their constituents and their larger numbers, the House is generally the more fractious and partisan of the two chambers. Its proceedings and deliberations, like those of the Senate, are recorded in the Congressional Record, ensuring transparency in the legislative process.

Criminal Justice Act Essay Example | Topics and Well Written Essays - 1500 words

Criminal Justice Act - Essay Example The 2003 criminal justice act allows the admittance of evidence against a person for a bad character during the criminal process. The new law was enforced in 2004 succeeding the previous common law and many of the statutory regulations that governed the bad character admissibility which was abolished following these changes. The new scheme that replaced them sets out conditions in which such evidence can be put into use in criminal procedures (Denis 2002) The new statute seems to have sent back the position in DPP v P. it would seem that the law disregards the attempt to keep away from inclination evidence following DPP. These changes have been manifested so much in the period after 1999 in cases like R v Humphris (2005), R v Nguyen (2005) and R v Black. Nonetheless, it’s evident that that criminal cat of 2003 discards some of the cases like an instance of the case of New South Wales Makin V Attorney-General-(Roberts & Zuckerman 2004). According to Lord Herschell, the crown was unable to adduce evidence and was inclined to indicate that the accused was guilty of other criminal acts part from those implicated by the indictment for the reasons of drawing conclusions that he is a person likely from the previous criminal record to have committed the felony for which he was to be tried. This outlawed line of thinking prevented the crown from putting up arguments the defendant was guilty based on his general predisposition to commit comparable types of felonies (Denis 2002).

Image analysis Essay Example | Topics and Well Written Essays - 1000 words

Image analysis - Essay Example Twitchell suggests that the human condition is one in which we have been inherently materialistic making us susceptible to the images we see. â€Å"We have always been desirous of things. We have just not had many of them until quite recently, and, in a few generations, we may return to having fewer and fewer† (Twitchell 471-472). However, in this material culture, where so many things are mass-produced in a variety of forms and substances, it is helpful to have some sort of guide to help us determine which things should be accorded the highest value and which things are not so great. This is where advertising enters the scene and helps us to define just what is valuable and what kind of meaning or history a particular object might have. It takes advantage of this natural human tendency to want to be comfortable and to have stuff to own, trade, protect or produce. However, despite our desire for increasingly more ‘stuff’, we nevertheless insist on being entertaine d if we are to pay attention to the message or the products it’s associated with. As a result, if advertising is to be effective, it must first appeal to the consumer in an entertaining or meaningful way, such as in the image taken by Peter Knapp in 1971. A basic description of this photograph reveals a greater than expected complicity. Upon first looking at the image, one is able to recognize a very pretty dark-haired girl with somewhat unusual features looking out of the page with an unfocused expression. Her face is heavily made up in what probably is underdone for the 70s generation. Her hair falls below her shoulders with somewhat messy curls gathering on her upper chest, but it does not extend longer than her armpit area. She has rich, peacock blue eye-shadow covering her eyelids which makes her seeming lack of eyebrows more prominent. She also has spots of pink rouge covering her cheeks in a way that looks less

Slavery Before the Trans-Atlantic Slave Trade Essay Example for Free

Slavery Before the Trans-Atlantic Slave Trade Essay What is the difference between slavery prior to the 14th century with that of slavery after the 15th century? Slavery existed long before the original slaves came to America. In fact, slavery prior to the 14th century differed greatly from slavery after the 15th century. Slavery was essential to many economic and social structures. For example, ancient Greece and Rome had many slaves. They differed from the form of slavery after the 15th century, though, due to the background of their slaves. Slavery was not necessarily racial or ethnic in origin prior to 15th century slavery. It was often captured enemies of war from many different places. However, when the Trans-Atlantic trade began, the majority of the slaves were African. Another difference is that the Africans were treated as objects, whereas prior to the 14th century, they were not legally the same as objects. Another difference is the jobs that they occupied. For example, the majority of the Athenian slaves were domestic servants, but the majority of African Americans had brutal and tedious jobs such working in fields all day. Slaves were also used to enforce religions, such as Islam. The Ottoman Empire forcibly converted approximately one million non-Muslims. However, the main purpose of Africans in the Americas was primarily as a work force. A significant difference was that of the Aztec slavery. For them, slavery was not considered hereditary. Therefore, a slave’s child was free. After the 15th century, a slave’s child was still considered a slave: it was hereditary. Slave trade was different before the Trans-Atlantic Slave Trade began.

Powerful Symbols in Their Eyes Were Watching God by Zora Neale Hurston

Powerful Symbols in Their Eyes Were Watching God by Zora Neale Hurston       In 1937, upon the first publication of Their Eyes Were Watching God, the most influential black writer of his time, Richard Wright, stated that the novel "carries no theme, no message, [and] no thought."   Wright's powerful critique epitomized a nation's attitude toward Zora Neale Hurston's second novel. African-American critics read a book that they felt satisfied the "white man's" stereotype of African-American culture and the humor which Caucasians saw in that prejudice. However, those critics and most of America overlooked the wonderful use of imagery, symbolism, and thematic application of one African-American female's journey into womanhood and self-identification in a male-dominated society. Hurston introduced Janie Crawford, a strong, articulate, and dramatic character whose life was best empathized by women or by inhabitants of migrant farms and rural Black towns. Their Eyes Were Watching God is permeated with recurring symbols, such as a pear tree, a fence-gate, and Janie's hair, that enlighten a young girl's quest for self-fulfillment, as she discovers the true meaning of love and happiness through two failed marriages and one successful but tragic third.    The strongest symbol in Their Eyes Were Watching God is the pear tree. The pear blossom is a representation of Janie, as she is a young girl blooming into a woman during a spring afternoon. Hurston explains this symbolism at the first of the chapter, describing Janie as à ¬a great tree in leaf with the things suffered, things enjoyed, things done and undone. Dawn and doom was in the branchesà ® (Hurston 8) Janie then lies beneath the tree, observes the bees pollinate a blossom, and ex... ...ecade of prejudice against African-Americans, women, and most importantly, African-American women.    Sources Cited and Consulted: Donlon, Jocelyn Hazelwood.

Is Odysseus a Hero Essay

I feel that Odysseus, like any person, can be a hero at some times and very selfish at other times. During the war in Troy, Odysseus was surely a hero, thinking smartly and protecting his men well. However, in books nine through twelve, Odysseus is definitely not playing the role of a hero among his crew. On almost any page you turn to in the book, you can find some act of selfishness coming from Odysseus. During his journey, Odysseus performs many courageous acts. At the island of the Lotus Eaters, he rescues his men from the addiction of the lotus flower. After the Cyclops captures them in his cave, Odysseus blinds the Cyclops with a sharpened log. Then Odysseus’ men sneak out of the Cyclops cave under sheepskins. Odysseus also performs a courageous act when he steers his ship around the deadly whirlpool Charybodis and valiantly tries to defend his men from Scylla, but she strikes to fast for him causing him to lose six men. When Odysseus arrives at the island of the Sun God’s cattle, he and his crew face famine. Therefore, when Odysseus falls asleep his men slaughter some of the Sun God’s cattle. Odysseus’s extreme pride and arrogance seems to cause trouble for him on many occasions throughout the book. Epic heroes ought to be proud of their accomplishments but they should not brag or expect things from people because of it. Odysseus’s pride and arrogance show up throughout the book. However, one occasion seems to stick out best. In book 9 of The Odyssey, Odysseus lands on an island bordering the land of Cyclops. He watches their brutish ways for days yet he still decides to pay them a visit. His men suggest taking the cheeses and animals but Odysseus refused (The Odyssey, Book 9). Odysseus fought gloriously on behalf of the Greeks in Troy and was considered a â€Å"war hero† of sorts because of it. However, he became to full of himself and did not give the Gods credit for helping him. That is why Poseidon punished him. He bravely endured Poseidon’s punishment and in the end learned that Man is nothing without the Gods. Therefore, I guess that makes him a hero, that he endured so much and learned a valuable lesson in the end.

Cell Phone hazards Essays

Cell Phone hazards Essays Cell Phone hazards Essay Cell Phone hazards Essay How cell phone is affecting us socially. Kazi Mehdi Rahman ID-1210910030 English-105, Section 7 Abdus Selim December 10, 2013 Perhaps you have had one of those moments when you look around in a crowded public place and it seems that everyone is either talking or tapping a message on a cell phone. Older individuals might wonder how things ever became this way, but for younger mobile phone users, this is the norm and all theyVe ever Known. ell pnones, texting ana smart pnone appllcatlon are nere to stay ana nave changed society in important ways, for better and worse. When a cell phone goes off in a classroom or at a concert, we are irritated, but at least our lives are not endangered. When we are on the road, however, irresponsible cell phone users are more than irritating: They are putting our lives at risk. Many of us have witnessed drivers so distracted by dialing and chatting that they resemble drunk drivers, weaving between lanes, for example, or nearly running down pedestrians i n crosswalks. Cell phones have increased the likelihood of traffic accidents and proven to damage young people communication skills. So we need to educate the public about the dangers of driving while phoning and also change the habit of the youngsters of using abbreviated text words. It doesnt take a rocket scientist to know that texting and driving is dangerous. But plenty of people continue to do it. Most troubling: even with all the stories of tragic car accidents happening as a direct result of distracted driving, teens and adults are still texting at the wheel. According to Kristin Marino (2012) text messaging increases the likelihood of accident by 23 imes, the minimal amount of time a person is distracted from road is 5 seconds, in 2011, at least 23% of the car collisions involved cell phones, 13% of drivers at the age of 18-20 involved in car accidents admitted that texting or talking on mobile phone was the reason for their car crash. No One can deny that cell phones have caused traffic deaths and injuries. Cell phones were implicated in three fatal accidents in November 1999 alone. Early in November, two-year-old Morgan Pena was killed by a driver distracted by his cell phone. Morgans mother, Patti Pena, reports that the driver ran a stop sign at 45 mph, broadsided my vehicle and killed Morgan as she sat in her car seat. A week later, corrections officer Shannon Smith, who was guarding prisoners by the side of the road, was killed by a woman distracted by a phone call Besthoff (2001). On Thanksgiving weekend that same month, John and Carole Hall were killed when a Naval Academy midshipman crashed into their parked car. The driver said in court that when he looked up from the cell phone he was ialing; he was three feet from the car and had no time to stop Stockwell (2000). The scientific literature on the dangers of driving while sending a text message from a mobile phone, or texting while driving, is limited. A simulation study at the Monash University Accident Research Centre has provided strong evidence that both retrieving and, in particular, sending text messages has a detrimental effect on a number of critical driving tasks. Specifically, negative effects were seen in detecting and responding correctly to road signs, detecting hazards, time spent with eyes off he road, and (only for sending text messages) lateral position. Surprisingly, mean speed, speed variability, lateral position when receiving text messages and following distance showed no difference(Hosking, Simon; Kristie Young, Michael Regan. A separate, yet unreleased simulation study at the University of Utah found a six fold increase in distraction-related accidents when texting. The low number of scientific studies may be indicative of a general assumption that if talking on a mobile phone ncreases risk, then texting also increases risk, and probably more so. Market research by Pinger, a company selling a voice-based alternative to texting reported that 89% of U. S. adults think that text messaging while driving is distracting, dangerous and should be outlawed. The AAA Foundation for Traffic Safety has released polling a a ta tnat snow tnat B % 0T people cons10er texting ana e-malllng while driving a very serious safety threat, almost equivalent to the 90% of those polled who consider drunk driving a threat. Despite the acknowledgement of the dangers of texting behind the wheel, about half of drivers 16 to 24 say they have texted while driving, compared with 22 percent of drivers 35 to 44. Texting while driving received greater attention in the late 2000s, corresponding to a rise in the number of text messages being sent. Over a year approximately 2,000 teens die from texting while driving. Texting while driving attracted interest in the media after several highly publicized car crashes were caused by texting drivers, including a May 009 incident involving a Boston trolley car driver who crashed while texting his girlfriend. Texting was blamed in the 2008 Chatsworth train collision which killed 25 passengers. Investigations revealed that the engineer of that train had sent 45 text messages while operating. On July 27, 2009, the Virginia Tech Transportation Institute released preliminary findings of their study of driver distraction in commercial vehicles. Two studies, comprising about 200 haul trucks driving 3 million combined miles, used video cameras to observe the drivers and road; researchers observed 4,452 safety-critical events, which includes crashes, near crashes, crash-relevant conflicts, and unintended lane deviations. 81% of the safety critical events had some type of driver distraction. Text messaging had the greatest relative risk, with drivers being 23 times more likely to experience a safety-critical event when texting. The study also found that drivers typically take their eyes off the forward roadway for an average of four out of six seconds when texting, and an average of 4. 6 out of the six seconds surrounding safety-critical events.

How Barometers Measure Air Pressure

How Barometers Measure Air Pressure A barometer is a widely used weather instrument that measures atmospheric pressure (also known as air pressure or barometric pressure) the weight of the air in the atmosphere. It is one of the basic sensors included in weather stations. While an array of barometer types exist, two main types are used in meteorology: the mercury barometer and the aneroid barometer. How the Classic Mercury Barometer Works The classic mercury barometer is designed as a glass tube about 3 feet high with one end open and the other end sealed. The tube is filled with mercury. This glass tube sits upside down in a container, called the reservoir, which also contains mercury. The mercury level in the glass tube falls, creating a vacuum at the top. (The first barometer of this type was devised by Italian physicist and mathematician Evangelista Torricelli in 1643.) The barometer works by balancing the weight of mercury in the glass tube against the atmospheric pressure, much like a set of scales. Atmospheric pressure is basically the weight of air in the atmosphere above the reservoir, so the level of mercury continues to change until the weight of mercury in the glass tube is exactly equal to the weight of air above the reservoir. Once the two have stopped moving and are balanced, the pressure is recorded by reading the value at the mercurys height in the vertical column. If the weight of mercury is less than the atmospheric pressure, the mercury level in the glass tube rises (high pressure). In areas of high pressure, air is sinking toward the surface of the earth more quickly than it can flow out to surrounding areas. Since the number of air molecules above the surface increases, there are more molecules to exert a force on that surface. With an increased weight of air above the reservoir, the mercury level rises to a higher level. If the weight of mercury is more than the atmospheric pressure, the mercury level falls (low pressure). In areas of low pressure, air is rising away from the surface of the earth more quickly than it can be replaced by air flowing in from surrounding areas. Since the number of air molecules above the area decreases, there are fewer molecules to exert a force on that surface. With a reduced weight of air above the reservoir, the mercury level drops to a lower level. Mercury vs. Aneroid Weve already explored how mercury barometers work. One con of using them, however, is that theyre not the safest things (after all, mercury is a highly poisonous liquid metal). Aneroid barometers are more widely used as an alternative to liquid barometers. Invented in 1884 by French scientist Lucien Vidi, the aneroid barometer resembles a compass or clock. Heres how it works: Inside of an aneroid barometer is a small flexible metal box. Since this box has had the air pumped out of it, small changes in external air pressure cause its metal to expand and contract. The expansion and contraction movements drive mechanical levers inside which move a needle. As these movements drive the needle up or down around the barometer face dial, the pressure change is easily displayed. Aneroid barometers are the kinds most commonly used in homes and small aircraft. Cell Phone Barometers Whether or not you have a barometer in your home, office, boat, or plane, chances are your iPhone, Android, or another smartphone has a built-in digital barometer! Digital barometers work like an aneroid, except the mechanical parts are replaced with a simple pressure-sensing transducer. So, why is this weather-related sensor in your phone? Many manufacturers include it to improve elevation measurements provided by your phones GPS services (since atmospheric pressure is directly related to elevation). If you happen to be a weather geek, you get the added benefit of being able to share and crowdsource air pressure data with a bunch of other smartphone users via your phones always-on internet connection and weather apps. Millibars, Inches of Mercury, and Pascals Barometric pressure can be reported in any one of the below units of measure: Inches of Mercury (inHg) - Used mainly in the United States.Millibars (mb) - Used by meteorologists.Pascals (Pa) - The SI unit of pressure, used worldwide.Atmospheres (Atm) - Air pressure at sea level at a temperature of 59 Â °F (15 Â °C) When converting between them, use this formula: 29.92 inHg 1.0 Atm 101325 Pa 1013.25 mb Edited by Tiffany Means

World Slavery Essay Example | Topics and Well Written Essays - 500 words

World Slavery - Essay Example Today, the most potent instrument of slavery is economic power as opposed to physical power. With most countries in the world joining the neo-liberal bandwagon, the power of money has established itself as the most potent instrument of perpetrating slavery. Previously, slaves would obey their masters for fear of the whip. But today, they do so for fear of starvation. Financial glottalization, euphemistically called neo-liberal reforms by most right-wing politicians, has contributed greatly to economic disparities across the world. In the thirty odd years since the initiation of the globalisation process, the income gap between the rich and the poor has only widened. It might be true that the Gross Domestic Products of several countries (especially those in Asia) might have improved during this period. But internally, the standard living for a majority of the population has stagnated or worsened. This kind of imbalance serves the interests of the rich perfectly, as they now have access to a desperate labour market that is ripe for further exploitation. It should be remembered that poverty is at its most severe in regions with high concentrations of wealth. This is why, prostitution has burst like an epidemic in Eastern European and South East Asian countries that have embraced neo-liberalism in recent decades. Since conventional notions of bonded slavery are not applicable in contemporary times, the parameters for evaluating its existence have to be modified as well. In this new understanding, slavery is closely associated with poverty. So if an individual is not able to eat two full meals everyday, or is unable to get access to basic healthcare, or does not have protection against natural elements, he/she can be said to be a slave. In this condition of acute deprivation, the individual will have no option but to take any work he/she is given at rock-bottom wages. In other words, the

Safety Management Measures For Organizations Essay

Safety Management Measures For Organizations - Essay Example Managers have to hire employees and influence employees by motivating them to take all the safety precautions and use all safety resources to ensure that the organization and its people are safe, these activities are conducted in the staffing and the directing function. 2. Employers use various incentive programs in order to stimulate and motivate employees to follow the safety guidelines and take all safety measures in order to keep the workplace safe and healthy (Friend 245). These incentives have a very short term effect, they bring about a positive change in the employees for as long as the incentive programs are in place. As soon as the employers discontinue these incentive programs, employees resort to working according to their prior standards and their standards even decline. They do so in order to persuade the employees to restart the incentive programs. Incentive programs are based on statistical data, the employees try to provide misleading statistics in order to persuade the employees to implement or continue with particular incentive programs. ... 3. Maslow came up with the theory known as Maslow’s Hierarchy of Needs, the theory states that each individual have 5 levels of needs and employers can motivate employees by helping them fulfill these needs. The theory states that all individuals first try to fulfill the basic level of needs such as the psychological needs and safety needs, and then they try to pursue the remaining needs in the hierarchy. Employers can motivate the employees to take care of the safety of the organization and the safety of the people working in the organization by providing them incentives so they can fulfill their needs. These incentives can help employees obtain food which is a part of their psychological need, employers can provide job security which will help fulfill employees need for safety, managers can make the employees feel that they are a part of the organization and this will help fulfill the need for belongingness, by assigning employees with targets and work employers can help ful fill the esteem needs of the employees. Once all the needs are fulfilled, the employees will start helping others in the organization and in their daily life which will fulfill the employees need for self-actualization. 4.
