Addicted to Coffee? Essay -- Biology Essays Research Papers

Addicted to Coffee? As a sophomore in college, I know how important it is to get that first cup of coffee in the morning. That first cup of coffee, second cup, and third cup seem vital to the well-being of Bryn Mawr students all over campus. They help us to stay awake through our classes, hours of study, and even time spent socializing. But is caffeine really addictive? Ask any Bryn Mawr student, and chances are that she will answer with an emphatic "Yes!" Ask any scientist or doctor the same question and the answer is likely to be just as emphatic, but what that answer will be is much less predictable. It is universally recognized that caffeine is a stimulant, a substance that causes the body to act differently from the ways that it would naturally act by inducing "fight or flight" reactions which cause the body to act in emergencies (1). However, it is still debated as to whether or not this stimulate is addictive. When deciding whether a substance is addictive, most professionals who make diagnoses in the United States and in many other countries will turn to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, better know as the DMS-IV. This manual is published by the American Psychiatric Association and lists, among other things, the symptoms of all mental health disorders. According to the DMS-IV, the symptoms of substance dependence (in other words, substance addiction) are substance abuse, continuation of use despite related problems, increase in tolerance, and withdrawal symptoms (2). The debate lies largely in the interpretation of these symptoms. What exactly constitutes a withdrawal symptom?

Organic Food Trends Essay

While these two factors affect the source of organic food, it is the retailers themselves who may trigger the fastest and longest-lasting drop in organic food prices. In response to the decline of sales, a looming price war may push organic food prices down to a level comparable to regular foods. The niche of people who are passionate about their organic foods will remain strong regardless of the price. When they were hot just a few months ago, many grocers and health food stores dedicated more space to stay ahead of the demand. Now that the demand has taken a dive, retailers will be trying to gain a stronger share of the shrinking market. Even Whole Foods, known for higher quality and prices to match, is reducing prices and trying to change their public image. It is in this price war that many who have recently abandoned organic foods may return for the same reason that they left: price. The actual cost difference between organic and normal foods is much lower than the retail price difference because perceptions have allowed the premium rates. As perceptions change, grocers will have to sell their normally high-profit organic foods at or below the cost of their normal counterparts.

The data indicate that Sainsbury’s, Tesco, Waitrose and Safeway account for most UK organic sales.

In 2006, organic food and drink sales nudged the ? 2 billion mark for the first time, and showed a 22% growth overall. Here’s why more people are choosing to buy organic: †¢Taste – Many people tell us they buy organic food because they believe it tastes better. †¢Food safety – Organic farmers, as far as possible, avoid using unnecessary chemical sprays. Food additives linked to asthma and heart disease are among those banned under organic standards. †¢The environment – Organic farming is friendlier to the environment so there is a much greater diversity of birds, butterflies and plants on organic farms. Organic standards ban the use of GM technology. †¢Animal welfare – Organic farming requires animals to be kept in more natural, free-range conditions with a more natural diet.

The top 10 food trends that are going to rule the food world are: 1- Eat Healthy! Health is going to be a major consideration that is going to influence our food habits. It would dictate the pattern of the foods patronized and also in turn what would be available in the market. The manufacturers are ready and eagerly waiting to take a cue from the consumption patterns so as to cash in on this multi-million dollar food market. There will, for sure, be an increase in health foods so as to cater to the demand of the potential customer. 2- Packaging Matters! With growing consciousness, it is important that the foods have a good and eco-friendly packaging and have all details specified on the label. These are definitely going to be the ones that would be preferred. 3- Go Local! An increase in importance to local produce is another significant trend that would be witnessed in the year 2008. Customers would prefer to patronize healthy food items that are grown locally. The growing environmental consciousness and an increase in importance to personal health are going are the reasons for this choice. 4- I want Ready-To-Eat! Convenience foods would however, continue to reign supreme. With people getting busier by the day and having very little time on hand, it is important to have more options for ready to eat meals. Complete meals of one or two dishes would be preferred. The studies conducted recently have gone to show that people prefer to eat at home for most part of the week due to health considerations and thus, convenient foods provide the perfect answer to a busy family that is also health conscious. 5- No McDonald’s for kids! With health of the family gaining priority, the healthy kids recipes is another area that is going to increase in importance. With several entrants in the market this trend is only going to grow by leaps and bounds in the coming months. 6- Weight loss meals get trendy! Obesity has come to be another major consideration that has come to have a significant impact on the food related decisions of a family. Weight loss foods that let you manage your weight problem without having to deprive yourself of the daily nutritional requirements is going to find favor in 2008. 7- Substitute capsules with food! With heart diseases and others becoming a major issue, foods that can fight diseases are going to be popular. Foods with antioxidants that have the property of fighting against diseases are what people are looking out for desperately. Keep the diseases at bay with a healthy and active lifestyle. 8- Indulge Yourself! The growing health consciousness is certainly not going to undermine the importance of premium foods that offer a wonderful reason to indulge. Pampering oneself with an array of exotic tastes and flavors – desserts, pies, and chocolate recipes – is going to be an essential part of our lives across the globe. Entertaining and discovering the treasure house that the culinary world offers are going to be a norm that would not change for any reason. 9- Go Veggies! There is definitely going to be a rise in the consumption of fruits, vegetables, whole grains and food with useful bacteria like yogurt. Useful bacteria are going to gain entry into many other food items that are part of our daily diet. 10- Raw Food Rocks! Increase in the consumption of raw food in the form of salads and other enticing dishes is going to be another of the food trends witnessed globally. The benefits of raw food will be explored across the globe. Source: http://my. telegraph. co. uk/butterbites/blog/2008/05/25/top_10_food_trends_for_2008.

The Voices Movie Review Professor Ramos Blog

The Voices Movie Review Ali Sakiri English 010 5:00 04 December 18 Can You Hear The Voice’s         It’s likely you’ve encountered someone with a mental illness at least once in your life, but it’s unlikely that they were violent, hopefully. In the movie â€Å"The Voices† it shows just that, Ryan Reynolds plays Jerry, a homicidal schizophrenic man who regularly spoke to his dog and cat. The animals represented both sides of his conscious as everything they said was entirely something of his making, the cat being evil and the dog being good. One scene in particular that rose many questions was after he claimed his first victim, he had unintentionally killed her and was conflicted about what to do so he consulted his animals. First the kinder side of his conscious, the dog, suggested that he goes to the authorities and they might understand while the cat had called both of them stupid and told Jerry to hide the body. Keep in mind that this was all in Jerry’s head, this was a great representation of how some schizophrenic individuals ma y associate their delusions with the the thoughts and feelings they have. This film brought up many questions for me. What is schizophrenia, how does someone get the disease, and do schizophrenic people have violent tendencies?         What is schizophrenia? According to The Mayo Clinic, schizophrenia is a mental disorder in which people experience reality in an abnormal way. The disease may bring along delusions, hallucinations, problems with speech such as putting words together properly in a sentence. A person with the disease may show signs physically of the disease such as poor personal hygiene, a lack of showing emotion, and not changing facial expression often. These symptoms are displayed very well in film, for example. After Jerry had claimed his first victim he had decided to finally start taking his medication. Of course he consulted his pets prior, and the response he received from his cat was, â€Å"Take those drugs, and you will enter a bleak and lonely world Jerry†(Marjane). He knew that he would be alone without his delusions and hallucinations or might even count on them as a support system. Once the effects of his pill set in, tons of his symptoms had disappeared, he was seein g the world for what it actually was and it was torture for him. He sat in his blood covered apartment and cried out for his animals to respond to him and begged with no response. Eventually the pill wore off and his animals could speak to him once more and his apartment was spotless in his eyes once again. His hallucinations and delusions acted as some kind of scapegoat from reality. This demonstrates very well the effect medication could have on patients with mental disorders may not always be seen as positive from the patient’s perspective.         What can cause schizophrenia? It’s believed to have plenty of possible causes such as substance abuse, a certain brain chemistry, complications at birth or early infancy and simply just passed on genetically. According to the National Alliance on Mental Illness, â€Å"While schizophrenia occurs in 1% of the general population, having a history of family psychosis greatly increases the risk. Schizophrenia occurs at roughly 10% of people who have a first-degree relative with the disorder† (NAMI). People with close family diagnosed with disease automatically puts them in the bracket for developing the disease throughout their life at some point. This is displayed very well in the film as Jerry’s mother is shown to have schizophrenia in a flashback to his younger years. In this scene Jerry’s father is seen abusing Jerry and calling both Jerry and his mother crazy.   During the whole episode he kept seeing his childhood sock puppet talking to hi m which solidifies that he was schizophrenic as a child. His mother even saying â€Å"I can hear the secret conversations of the world†(Marjane). In this case it’s very likely it was passed on genetically.         Not all schizophrenic patients are homicidal, or even violent at all. While most tend to lead peaceful lives out of the frame with no intent of harm towards others. However it is not unlikely that there may be a link between schizophrenia and homicidal tendencies. A study in Australia done on 435 inmates convicted of homicide found that 38 of them were diagnosed with schizophrenia. That was roughly about 8.7 percent of the inmates in the sample while about only 1 percent of the general population is diagnosed with the disease. Why was this population more than 8 times larger than what it is for the general population? The only key difference in these populations is homicide, bring in homicide and suddenly the rates of those diagnosed rises. It can’t be a coincidence and according to James Ogloff, J.D., Ph.D, it’s not. James is quoted as saying ‘Patients with schizophrenia are significantly more likely than those in the general community to commit hom icide offenses, (Sinclair)   This is not to say that all people diagnosed with the disease are homicidal and violent, but simply highlighting the fact that with their symptoms, physicians opinions, and the increase of schizophrenia amongst criminals who committed homicide, it’s impossible not to associate a link between the two.         The film â€Å"The Voices† truly emphasizes the negative effects of schizophrenia.The movie properly displayed what the effects of schizophrenia have on a person with Ryan Reynolds playing a very convincing schizophrenic. He showed the hallucinations, delusions and lack of personal hygiene very well with Jerry’s pets speaking to him on such a frequent basis and the apartment being covered in blood and human remains when he’s on his medication. Sadly this film also sheds light on how difficult it is treat schizophrenia efficiently as Jerry avoids his medication for practically the whole film It also has a comedic undertone which gave this movie some very funny dialogue. Overall I’d give this movie a 80%, the plotline developed very quickly and definitely grabs the viewer’s attention but also fails to deliver some background and brings up some unanswered questions. It had a 11 million dollar budget and it didn’t even make $500,00 so the movie technically failed on paper, but if you choose to ignore that I think you’ll catch yourself watching this movie more than once! â€Å"NAMI.† NAMI: National Alliance on Mental Illness, www.nami.org/Learn-More/Mental-Health-Conditions/Schizophrenia. â€Å"Schizophrenia.† Mayo Clinic, Mayo Foundation for Medical Education and Research, 10 Apr. 2018, www.mayoclinic.org/diseases-conditions/schizophrenia/symptoms-causes/syc-20354443.

Dissolve Styrofoam or Polystyrene in Acetone

Dissolve Styrofoam or Polystyrene in Acetone Dissolving Styrofoam or another polystyrene product in acetone is a spectacular demonstration of the solubility of this plastic in an organic solvent. It also illustrates just how much air is in the Styrofoam. All you need to do is to pour a bit of acetone into a bowl, and place Styrofoam beads, packing peanuts, chunks of foam, or even a Styrofoam cup in the container. The Styrofoam will dissolve in the acetone much like sugar dissolves in  hot water. Since Styrofoam is mostly air, you may be surprised by how much (or, in the end, how little) foam will dissolve in the acetone. A cup of acetone is enough to dissolve an entire bean bags worth of styrofoam beads. How It Works Styrofoam is made of polystyrene foam. When the polystyrene dissolves in the acetone, the air in the foam is released. This makes it look like youre dissolving a massive quantity of material into a small volume of liquid. You can see a less-dramatic version of the same effect by dissolving other polystyrene items in acetone. Common polystyrene products include disposable razors, plastic yogurt containers, plastic mailers, and CD jewel cases. The plastic dissolves in just about any organic solvent, not just acetone. Acetone is found in some nail polish removers. If you cant find this product, you could dissolve styrofoam in gasoline just as easily. Its best to do this project outdoors because acetone, gasoline, and other organic solvents tend  to be toxic when inhaled.

Disability Wheelchair Essays

Disability Wheelchair Essays Disability Wheelchair Essay Disability Wheelchair Essay Nancy Mair’s â€Å"Disability† shows us the view a disabled woman has on how the world perceives people with disabilities. Nancy is â€Å"a forty- three year old crippled woman.†(Bedford Reader 13).Nancy is a woman who spends most of her time in a wheelchair. A woman that can be easily spotted in a crowd. She notes that she has not 3show that illustrated her so that people would feel sorry for the woman. They show the woman trying to make one lat trip before she gets crippled. Nancy thinks the show depicts her as unable to make her own choices. She wanted to go to Kenya but her doctor would not let her. Mairs sees the show only showing the fact that she’s disabled but â€Å"excludes the complexities that make her a whole.†(Bedford Reader 14) Mairs considers herself an American Consumer. She uses things that everyone uses in day-to-day life. She’s bothered by the fact that no advertisement ever includes disabled people. The reasoning she thinks behind it is that if they show disabled people doing everyday activity, it will demonstrate how disability can affect anyone. This will make people fear their reality. She thinks that this isolation of disabled people is harmful and even dangerous to the disabled. It makes them feel invisible and almost as if they did not exist. She thinks the only way to integrate disabled people is as quietly and as naturally as possible into people’s everyday life. In â€Å"Disability† Nancy Mairs is trying to show that disabled people are just like regular people. (Bedford reader 14) .And therefore they should be treated as regular people. Mair’s trouble is with advertisers and how they refuse to include the disabled even though the disabled also use their products. She hates the fact that society is obsessed with appearance and normality. She concludes that they don’t use disabled people because of they fear it will cause people. It can show them that disability can affect anyone and everyone. Although Mairs is disabled she prefers to be called crippled. She does not like people feeling sorry for her and that comes along with the word disabled. And the fact that someone might only be nice to her because of her being disabled scares her. Although Mairs needs help  from everyone around her she thinks she can perform everyday tasks just like everyone else. She thinks that if you are crippled that life can still be great and that really it all comes down to you and what you make of life. On a personal note I think Mairs is a great example to follow. She embraces how she is and makes the most of it. She does not complain for the regular things like everyone else. She complains about things that are important and makes her points. She lives her life to the fullest and I think a lot of people could use some of that. People without disabilities do not see or appreciate the things they are able to do each and everyday with ease. They only complain about things that do not matter. But people like Mairs live everyday as it were her last. I would like to read more of Mairs, and I think anyone who complains all day and does not see what other people go through should read what Nancy Mairs has to say.

I will attach the documents - Essay Example It is not to argue that the conditions of slavery still too exist without any substantial changes. Of course, blacks have progressed a lot and the same goes for the way the mainstream society looks at the black people. But, what remains unchanged or being endlessly reproduced is the slave mindset. It is the very legacy of the slavery that it still permeates all the aspects of social life of the nation in general and the personal lives of black people in particular. The effects of slavery are continuingly expressed in the family lives, world outlook, and self respect and so on of the black people. Issues and Concerns of Black Liberation Breaking the Chains of Psychological Slavery is a groundbreaking study in the field of cultural psychology. Akbar has famously asserted that â€Å"slavery that feeds on the mind, invading the soul of man, destroying his loyalties to himself and establishing allegiance to forces which destroy him, is an even worse form of capture. The influences that p ermit an illusion of freedom, liberation, and self-determination, while tenaciously holding one’s mind in subjugation, is the folly of only the sadistic† (Akbar, 1996, p.VI). ... Here, although I completely agree with Akbar’s proposition that the legacy of slavery is still tormenting both the minds and souls of black people, it is difficult to buy his argument that black people are completely subjugated by the master narrative. For Akbar, the subjugation of blacks or the mental colonization of the blacks by the whites is total, unlimited and infinite as it knows no outside. From a dialectical perspective, on the contrary, one could argue that the white/black relationship is mutually dependent and, at least in the mental space, the blacks are more liberated than the whites as they have nothing to lose from the abolition of slavery. In other words, the idea of total ‘capture’ of black mind by the oppressor ideology itself is a negation of the subjectivity and active agency of the black people. It does not hold true if we look at the real life examples. In many cases, it is not through a hegemonic ideology, but through sheer repression (throu gh ku klux klan or police/military actions) and economic violence (denial equal opportunity, discrimination etc.), the black bodies are made to be docile. For Akbar, the problems of the blacks that arises not only from the retrogressive material conditions which exist in a repressive White society, rather, he locates the black subjugation in the realm of consciousness by arguing that â€Å"the slavery that captures the mind and imprisons the motivation, perception, aspiration and identity in a web of anti-self images, generating a personal and collective self-destructive, is more cruel than the shackles on the wrists and ankles† (Akbar, 1996, p.V). Here, also, Akbar fails himself into the deeply entrenched racist trap and believes that the power of the master is all-pervasive

Education Technology Essay Example | Topics and Well Written Essays - 500 words

Education Technology - Essay Example Also even if the students are willing to go to school despite these situations, they are unable to attend because they are needed in the farm or in the chores in their homes. It is in these situations where governments and education sectors should involve the use of technology in providing education. There are a number of NGOs and multinational companies who are willing to fund projects in relation to these. In the Philippines for example, a television network partners with generous organizations in bringing Sineskwela or School on Air to remote areas (Sineskwela, 2009). The Sineskwela is an educational show, covering all the various subjects of primary education delivered through dramatizations and a lot of visual effects. The objective is to make learning fun and interesting and delivering it not only to formal schools but to homes as well and to those who have no access to quality education. Some organizations are providing computers and television sets to schools located in depressed areas all over the world. In India for example, a lot of organizations have been donating computers to schools that do not have sufficient funds to provide computer education or at least use computer technology in delivering classroom teaching (Agarwal, 2007). These are instances where technology is used in carrying out the teaching and learning process, both as a support to the teaching and also as the teaching process. Technology has been recognized all over the world to be that powerful force in bringing about change, and in this case, change in the educational system. The use of technology in education has been around for quite a while and has already been institutionalized in the sense that this is incorporated in teacher education curricula all over the world so that teachers will be equipped with the necessary skills and know-how with respect to the use of technology in education. Virtual classrooms and distance learning or
