The theory is that when you are cutting your sleep short that you are making your day harder than it has to be and with the proper sleep you could get things done more efficiently. Sleep is something that we all depend on and when we cut it short it leads us to feel tired, moody, and very sluggish. If you continue to get less sleep and it becomes chronic, it can lead to things like weight gain, memory loss, and impairment of motor skills. (Smith, Robinson, Segal 2012) It’s estimated that twelve and a half billion dollars in total damage due to car crashes caused by driver fatigue and fifteen hundred people have died from the fatigue caused by lack of sleep. (Arams)
The more sleep you miss out on can contribute to a thing called ‘Sleep debt.’ Just as any debt this is when you are missing out on a lot of sleep. Just how much sleep do we need? Adults need ideally eight to nine hours to feel fully rested and at our peak. (Schwartz, 2011) Teenagers need around eight to ten hours of sleep, and infants need fourteen to fifteen hours of sleep. (Smith, Robinson, Segal 2012) Three good tips to work towards paying off that sleep debt are: go to bed earlier, start winding down at least forty-five minutes before you turn out the light, and writing down what’s on your mind.
It’s not just the quantity of sleep that we get it’s also about the quality. There are two forms of sleep, REM (Rapid Eye Movement) and Non-REM. (Chokroverty, 2010) There are three stages of Non-REM sleep. Non-REM sleep accounts for around seventy-five to eighty percent of our sleep and each stage last approximately ninety to one hundred and ten minutes. (Chokroverty, 2010) REM sleep is around twenty to twenty-five percent of our sleep and of course is characterized by the rapid eye movements we have during this stage.
One thing that tends to stop people from sleeping is the actual pressure of…...

How Does Media Affect Us

...of manipulatable species where the media feeds off this ever-growing trait that lies within us all. It affects us in so many ways both consciously and otherwise, where half the time we aren't aware of what it is doing to us.

Let's take a look at the good and bad side of media's influence on culture. ✔ +tive Aspects ✘ -tive Aspects The media has its way of showing us constructive information when it comes to news channels, travel and other educational shows. Kids benefit from watching these, since it can boost self-esteem, heighten interest levels in a particular subject, or encourage them to ask relevant questions. Violence is a major factor when it comes to media, being a potentially dangerous instigator when it comes to young audiences. Kids are influenced easily by what they see on television or the Internet, mimicking such acts (if not as extreme, though on the lines of violence) on elders, or kids their age.

How Difficult Is It to Amend the Us Constitution?

...There have only been 27 constitutional amendments since it was created. This shows how difficult it is to amend the constitution and rarely it is amended; only 17 of the amendments have happened in the last 210 years. There are four key reasons why it is hard to amend the constitution but there are other reasons, not to do with the amendment process, that have meant the constitution hasn’t been, or needed to be, amended. The first reason is that the Founding Fathers created a deliberately difficult process. To amend the constitution both Congress and that States have to agree using super-majorities. The use of super-majorities makes the process even more difficult. This is shown by the hundreds of amendments that have been proposed but not successfully carried through and legitimised. The need to get support from a super-majority in all the States is also very time consuming and costly and so it is even more difficult for politicians to get and amendment passed. Furthermore there is a huge percentage of the American population which are at opposing sides of the American political compass. This means that it is often very hard to get everyone to agree to the same policies and amendments and therefore very difficult to get a super-majority at state-level. The process created by the Founding Fathers means that it is incredibly difficult to amend the constitution but it wasn’t just amendment process they created which limits the number of amendments. The Founding Fathers also...

...of animals to become extinct.  Even though Global warming is increasing in our planet there are steps that can be taken to slow down the process of global warming. We need to become more energy efficient. Reducing our use of oil, gasoline and coal usage. While using alternative fuels such as natural gas, wind, solar, hydroelectric (the way the Hoover dam runs) which reduces mainstream greenhouse gases. The best thing we can do is go green. Cutting down our energy costs, buying a fuel efficient car such as a hybrid or a car that runs on hydrogen or ethanol. Recycling is the best thing we can do at this point as it cuts down on greenhouse gases the most. One of the reasons why recycling is important is because it helps us save natural resources. It also helps reduce energy usage, it would take a 64% of energy to make paper rather than you recycle it. Recycling is an easy thing anyone can do, from young kids to the elderly. Its a simple thing that can be taught from a young age that makes a huge difference in the world for not only you but everyone that lives in it. Maybe we can make so much of a difference we can advance our technology one day to the point where no greenhouse gases are polluting the atmosphere through pollution.

Robotic Technology and How It Helps in Hospitals

...in an innovated way. Surgery today is much safer than it was a few years ago. Today the doctors are not always going into the operating room to perform the surgery. Some doctors are able to do the surgery from the comfort of their own home with the use of robots and computers that we have today. In 1985 was around the starting time for robots to help out in the operating room. The Puma 560 was used to place a needle for a brain biopsy using the guidance of a CT scan. Three years later it was used to perform a transurethral resection. Robots that are used in surgery today need to be top of the line and well maintained to perform in the operating room. Yes today robots do the job of surgeons however there still needs to be a surgeon on hand in the hospital in case there is a malfunction or if something goes wrong during the surgery. There has been a lot of major inovation in the field of robotics from the use of robotics to do the first Laparoscopic surgery (a cholescystecotomy) to being used to perform prostatic surgery by the Probot. The ROBODOC whis is from the integrated surgical system was introduced in 1992 to help with precise fittings in the femur for hip replacement. There was further robotic development that was carried out by Computer Motion with AESOP and ZEUS robotic surgical systems and Intuitive Surgical with the introduction of the da vinci surgical system.

How Does Steinbeck’s Portrayal of Lennie in Chapter 1 Help to Prepare Us for the Dramatic and Later Events in the Novel?

...Chapter 1 can prepare the reader for later events because Lennie is portrayed as a character that doesn’t learn from his mistakes. In the first chapter the descriptions of both Lennie and George are displayed to introduce them; ‘A huge man, shapeless’ (page 20). From this description of Lennie it conveys to the reader that he is lifeless. This lifelessness could suggest that Lennie isn’t happy and is reflected upon how he walks as well as how he represents himself. The reasons why Lennie may feel upset could be due to the Great Depression and the Dust bowl. The Great Depression lead to 15 million people unemployed and the Dust bowl happened when people over farmed which lead to crops not growing. However from chapter 1 it conveys Lennie and George as being poor due to what they wear; ‘demin trousers and in demin coats with brass buttons’ (page 19). Wearing demin in the 1940s indicated people being in the poor working class. The reason for this is because demin is hard wearing so it will last a long time which is useful for workers. The Great Depression would have mostly affected the middle and upper class. The Dust bowl would have massively affected Lennie and George because a series of droughts lead to many farms no longer being able to operate. This would have meant it would be extremely hard for Lennie and George to find a job. Furthermore, people heard that in California the soil was still good and there was plenty of room and opportunities for work. This may...

How to Sleep Through the Recession

...20 Steps to sleep thru a recession When the word ‘recession’ is utterred, what springs to your mind? Chances are, there will be pictures of men in working caps and shabby, worn-out jackets, bearing ‘will work for food’ signs. Hard work to earn your bread and butter, with more hard work for dessert. In other words, an idler’s hell. Or is it? Bless your pillows, the end might not be nigh. This is a guide, sculpted and polished by personal experience, that will try to tuck you back in bed. Step 1: Get a job. [doesn’t sound like we’re off to a good start, does it?] Overplay all your (or anybody’s) qualities beyond belief and reason. Make up intricate stories for the qualities you don’t have. Remember, CV should always stand for Creative Void when you’re writing it. That should make it quite easy for you to get a pretty good, highly-paying job, especially if you are going for the services business where no one asks you any real rocket science questions in the interviews. Target a firm that is bound to face trouble (the adjective ‘new’ before the sector of the company tends to work quite well: look out for new economy, new media sectors). Now that you have presented yourself as The UltraEmployee(, there will be few people who will resist your Oxbridge PhDs, your JavaScript excellence and the 5 languages in which you are fluent.

Place and How It Shapes Us

...William Holloway Professor Kitty Nard ENG 115 10 December 2013 Venice Beach: The Definitive Place of Los Angeles When many people think of Los Angeles, they have these preconceptions that Los Angeles is associated with shopping, entertainment, art, the beach, and its well-known sense of escapism it offers many people who live there. Considering this is how most of the world views Los Angeles, these are their preconceptions when they come here to visit. When foreigners come here, they tend to believe that Los Angeles is a place that is stricken with glamor and elegance. This ideology is attributed to the modern Hollywood film culture that Los Angeles is closely associated with. However, once they come here they realize that, just like most cities, Los Angeles has an upper class suburban area that is very enjoyable for those who live there, and a sketchy urban area which is not as pleasant as the well-kept suburban areas. Unfortunately, there are very few places where you can experience all of these aspects of Los Angeles. This is due to the fact that Los Angeles is a very fast paced city, which sometimes makes it difficult to experience the city the way you intended. However, Venice Beach is a place where you can experience everything Los Angeles is associated with: its shopping, entertainment, art, and the beach. Unlike most places, Venice Beach is very rare in the sense that is offers the more sophisticated side of Los Angeles, while also capturing the city’s......

How Financial Assessments Help Organizations

...How Financial Assessments Help Organizations Managerial Analysis Abstract Financial assessment provides management with the ability to make critical business decisions for their organization; this involves examining existing data to gain insight on the current and future condition of their organization through the balance sheet, income statement. In the book, What Every Manager Should Know about Financial Analysis, Alan Donahue states “The inability to understand and deal with financial data is a severe handicap in the corporate world”, which seems fitting to mention as I discuss in this paper the significance in doing a financial assessment and some of the necessary tools that are needed in order to do a financial assessment. Basic Concept of Financial Analysis for Organizations and its Importance Financial analysis is an assessment of an organization that will determine the organization’s risk and profitability through reported financial information; the two main sources for retrieving such information are the balance sheet and income statement. The balance sheet also provides a wealth of information that enables the organization to determine its stability, vitality, and profitability through utilizing ratios. Ratios can determine the overall performance of the company through such things called liquidity, leverage and profitability. Balance Sheet The balance sheet outlines the the financial and physical resources that a company has......

How Does Sociology Help Us to Understand 'Class' as an Important Social Phenomenon?

...How does sociology help us to understand 'class' as an important social phenomenon? Sociology emerged in the nineteenth century as an attempt to understand the transition from traditional to modern society.  Many argue that class is no longer important as a social phenomenon as an individual’s identity are based more on status and cultural factors such as lifestyle, values, intelligence, education. Others argue that class is still a central influence on people’s lives, that it affects their life chances. They argue that class inequality exists and that such inequalities are widening rather than narrowing. The major perspectives historically have been Marx and Weber who have provided their views and support for the idea that society is class-conscious. Other theorists, such as Clark and Lipset challenge Marx and Weber theory and believe that class is not an important social phenomenon. The common stratum model of class divides society into a simple hierarchy of working class, middle class and upper class. Class is an important social phenomenon that exists in society and through sociology we are presented with a variety of concepts and theories that contribute and support our understanding of the classes.  A class system “refers to a social group, defined in terms of its economic position in a hierarchy of inequality and with material interests that differentiate it from other classes.” (Van Kriken; Habibis; Smith; Hutchins; Martin; Maton, 2014, P.205).  The most common...

How Is the Historical Era Reflected in the Help

...How is the historical era reflected in The Help The Help is a movie which depicts the historical era in 1960s, specifically in Jackson, Mississippi. The story revolves around a writer called Skeeter who tries to convince the black maids there to give her stories and confessions of how it feels to work for white women. The movie tries to give other people a view into what was it like for the black women 50 years ago, but many think that it has failed to do that. The first and probably most important fact that the movie has missed, was the violence and sexual abuse against the black women. The movie showed how the white women and men pretty much disgusted the black women and wouldn’t even touch them. That was true, but only in public. It was often so, that when a maid was in private with the people she was working for, she was beaten and often sexually abused. In the movie though, the only violence we see is when Mr Evers is murdered, and that too is only shown in the TV, and when Minny was beaten up by a husband we did not get to see. This has been the main issue with the movie and has been criticized often. Another problem that has not been brought out in the movie correctly is that black men are mostly betrayed as cruel or absent. I already brought out an example of how they were cruel in the last paragraph, how Minny was afraid of her husband and how he finally beats her. As for absent, we can’t really see the black men in their homes, taking care of kids or such. It......

How to Help at Risk Students Graduate

...in urban high schools in majority cities (Balfanz, 2007). Many schools do not have a system that identifies students who are at-risk of dropping out school, so these students are ignored. And even some schools that have indicators in place, they do not offer adequate assistance to help these students (Princiotta & Ryan, 2009). In urban high schools, difficulty transitioning from middle school to high school can increase dropout rates and reduce on-time graduation (Princiotta & Ryan, 2009). Recent studies show that most ninth graders that enter nonselective urban high schools enter with academic skills that are several years below grade level, and that students that dropped out had severe academic problems in the ninth grade (Kemple et al, 2005). Therefore it is very important to establish drop out prevention during the critical time. The Talent Development High School is a reform model was created to address the needs of urban schools. It was used for reconstructing large high schools with persistent attendance and discipline problems, poor student achievement, and high school drop out rates (Kemple et al, 2005). In this paper, I will discuss the implementation of the TDHS model and how it would be evaluated and supervised in Uniondale High School. Chapter 2 Literature Review High schools around the country are looking towards creating small learning communities as a solution to current problems happening in urban high school. In A......

Will a Longer School Year Help or Hurt Us Students

...Will Longer School Year Help or Hurt US Students In the article, “Will Longer School Year Help or Hurt US Students” by Julie Carr Smyth it questions whether or not having a longer school year would be beneficial to students. It highlights the option of continuing school all year long and adding three equal vacations in each third of the year, centered around holidays. I believe that this idea would be smart and that it should be put into place. The first reason why I believe that having a year round school schedule would be beneficial is because it would give the students less time to forget the material they had been studying the grade before. The article states, “Proponents argue that too much knowledge is lost while American kids wile away the summer months apart from their lessons” (Smyth n.p). It has even been tested that student’s test scores are high at the beginning of the school year opposed to at the end before school starts back up, and that only 10-15% of the student body did not lose any knowledge. That means that a whopping 85-90% of the student body did lose knowledge over the summer months. The second reason why a system like this would work is because it would give lower class children a chance to get free school lunches year-round. Smyth states, “Supporters also say a longer school year would give poor children more access to school-provided healthy meals” (Smyth n.p). During the school year some children’s most filling and healthiest meal......

How to Create Jobs in the Us

...How do We Create Jobs in the United States? By Ronald W. Spahr Everyone, including politicians and economists, agree that we need to create more jobs in the United States; however, significant disagreement exists among these groups on how best to achieve this goal. Many economists, especially those currently in Washington, believe that job creation begins with increasing the demand for goods and services, the demand side, espousing remnants of Keynesian economics. However in a world of global economic competition, merely creating additional demand for goods and services does not necessarily translate into job creation in a specific venue. Increasing demand must also translate into increased capital formation, job creation and productivity in the same country or economic venue. This supply-capital formation component is missing in the attempts at economic stimulus in the United States and in many western European countries. In a competitive global economy with increased capital fluidity, capital tends to flow to venues (countries) that offer the highest risk-adjusted returns. Thus, countries around the world are competing for capital and resulting job creation in a world with heterogeneous tax structures, standards of living, levels of infrastructure development and human and natural resources. The ability to attract capital depends on these factors as well as possibly other factors, where it is not readily transparent which countries posses......
