Current Event Alcohol Essay Example for Free

Current Event Alcohol Essay This article is very surprising in the fact that the understanding of binge drinking is changing. It has been apparent for some time now that excessively drinking has been a problem but it is now under the microscope of having a positive light to the young population. This study had articulated how binge drinking is being looked at and what is changing across student college campuses. The article was based within a college campus, they were studying who or why college students binge drink. They found that students that are perceived as being â€Å"high status† are socially connected and mentally happier. On the other hand those that are considered â€Å"low-status† were deemed to not being as happy, especially in terms of the satisfaction of their college life. This study is trying to show college students correlation with alcohol and what may be happening as a whole within a certain community. As college students we are known to have very high stress, alcohol, is said to help lower this stress. The national institute on alcohol abuse says,†over 400,00 students between the ags of 18 and 24 had unprotected sex as a result of their drinking† all of these statistics are worrisome. It is hard to understand why this is becoming such a problem but as it is described here, it can be directly associated with peer pressure and failure of education about the matter. Binge drinking is a major problem within our society. Even though this article is only from one university it can be multiplied and used to inform and educate other universities across the United States. If we don’t understand the effects it is making now we will not be able to control the future generations. This is particularly close to family ties considering many young adults are dying every year from excess drinking. From the article they state that, â€Å"1,700 college student deaths can be attributed to excessive drinking. † This statistic alone proves that it is a problem that could be prevented with proper education or different drinking laws. The culture within the United States put such a high emphasis on drinking. We learned and talked about how when something is illegal it makes more people want to try it or use the certain substance, I believe this can be directly connected with alcohol in teens and young adults. It I no urprise to me that the statistic of those that are classified as binge drinkers is so high, they say it is â€Å"peer pressure at its finest†, but I wouldn’t only correlate it to be from that but also from our; parents, educators, and role models not creating a clear understanding of how dangerous it can be and is. I agree with their statement that, †we want to make clear that we believe binge drinking is a really dangerous and ultimately self destructive behavior, and that a social power structure that promotes this is a bad thing†. This sentence really amplifies the need for change. This article is almost making a plea for people to understand and have knowledge of this subject. It has been passed over and if we don’t stop this power trip alcohol is having on young adults we wont realize when we have changed the older generation of society as a whole. On the other hand I believe since this was only done within one small university, in order to have collected and statistic information more studies would need to be done to find an average across the United States. This article was an eye opener for me to some of the crazy statistics that are out there and primarily tied to the use of alcohol. This study is only one example of how alcohol is affecting our society. It may makes some college students happier about their college experience but in the long run it will catch up to you and hurt not only yourself but those around you, as we have talked about this many times in class. Overall I would hope you evaluate your own personal decision and decide what is your best option. Don’t let other dictate how you should live or what they think is the best way to live.

Cloning - Stronger, Smarter, and More Perfect Humans :: Cloning Argumentative Persuasive Argument

Cloning - Stronger, Smarter, and More Perfect Humans A few years ago if you were to ask someone about the possibilities of cloning they would most likely say it was impossible. This attitude towards cloning has been held into belief up until recently when scientists in Scotland cloned a sheep. And immediately after scientists in Oregon cloned a monkey (Fackelmann 276). The most major breakthroughs of the century in science has occurred and we are not ready for it. The scientific breakthrough of cloning has caused a great deal of controversy in the media and also in the government. The advantages of cloning are tremendous to the human race and cannot be ignored. I believe that cloning humans is what the human race needs to advance. Humans would be stronger, smarter, and more perfect. Scientists could remove bad genes from the parents and replace it with a good one. If one of the parents had a bad gene or hereditary disease this could be removed from the embryo and replaced with another "clean" gene. This process is called embryo screening it is used to determine if the child has received the defective gene. Several embryos could be cloned, then the DNA from one of the embryos would then be removed and standard genetic testing would be used to detect whether or not that embryo contained the genetic disease. If this cloned embryo containd a disease then one of the other embryos could be used for implantation in a parent, this guarantees that the child would be free of genetic disease (Marshall 1025). For those who disagree with cloning I am sure if there child could be saved from a genetic disease they would reconsider cloning. Imagine if one of your friends or family members was in need of a liver or kidney. Most likely you would donate your own liver or kidney to save there life. But then you are one organ short. Well this happens a lot and seems to work fine. But if they needed a new heart you might have trouble finding one. Not if you had a clone of yourself that could supply you with a new organ or maybe even a relatives organ that was naturally stronger (Cloning 1117). Someone could replace their old organs with new ones and extend their life span. Thousands of lives that could be saved if we had the technology and advanced science of cloning available. Even accepting an organ from a relative it may fail, it has to be compatible with our body system , if its your clone, then its

Kinship and the Inuit People

It takes a certain type of person to be able to survive the harsh freezing climate of the Arctic. The Inuit, descendants of the Thule have been surviving along the shores of the Arctic Ocean, Hudson Bay, Davis Strait, and Labrador Sea for over 1,000 years. The kinship relationships among the Inuit people are very important to their way of life and survival. Every family unit consists of the nuclear family. This is the most common type of unit in a foraging society, such as the Inuit. The nuclear family is the mother and/or father and their children. Occasionally, the Inuit nuclear family will include a spouses’ widowed mother or father or a single adult sibling. The village will contain several other households sharing kin members. This is important because they participate in generalized reciprocity. Generalized reciprocity is a form of exchange where there is no expectation for the immediate return of an item or service in exchange for something else. The different households visit each other, share food, and work together to complete everyday tasks. During the seal hunting season, about 15 different households come to work together. This is very important because seals are used for more than just their meat. They use the sealskins for various things such as boot liners, waterproofing clothes, houses, and kayaks, and the blubber for household lighting. However, â€Å"whenever food was abundant, sharing among non-relatives was avoided, since every family was supposedly capable of obtaining the necessary catch. In situations of scarcity, however, caribou meat was more evenly distributed throughout camp† (Laird & Nowak, 2010, p 3. ). This generalized reciprocity helps to ensure the survival of the people in times of need. However, because it is not done all the time, there is little conflict. During times of scarcity, the Inuit people have practiced infanticide. One of the reasons they do this is so the older children or adults do not starve. However, it has been noticed that they prefer female over male infanticide. This is most likely because the boys will grow up to be the hunters. A few women do hunt, but it is considered the men’s responsibility. Women do contribute to the food by gathering grasses, berries, tubers, stems, and seaweed. However, because there is very little vegetation in the Arctic, women are not the main contributors of food. They process and prepare the meats the men bring home. Women are expected to take care of the children and the house. This is one of the closest similarities between our culture and theirs’. In our society, women are still considered the primary caretaker of children and elder family members. Women are expected to come home from work or â€Å"berry gathering† and prepare dinner. Women run the household chores such as cleaning and laundry. Inuit women clean and sew for the children and men, except when the men go away to hunt and have to do it themselves. In our culture, men sometimes help with household chores, such as cooking, although they have the option of ordering in. Our culture also practices generalized reciprocity. Families gather together to share meals and everyday chores. We go to visit other households to enjoy holidays and birthdays. Family members exchange gifts, foods, and just enjoy being together. Some families gather to help one another out like when we moved. My father-in-law helped by lending us his truck. There was nothing expected in return. The one thing we do not share with the Inuit culture is infanticide. Although I understand why they do it, I would not be able to. In our culture, the parents would end up in prison. We also do not place as much importance on the sex of the child. The only benefit of a boy would be the passing on of the family name. However, today women can decide to keep the family name and add on their husbands, instead of giving up theirs for his. Although our cultures have many similarities, they are also very different. Kinship relationships are important in every society, including ours and the Inuit. However, our survival is not dependent on these relationships, whereas the Inuit are. Without the kinship of the Inuit, they would not be able to survive the harsh winters of their environment. It does take a very special type of people to survive the Arctic. The Inuit have proved to be one of them.

Ib Physics Chapter 3 Notes

I did not understand how to explain why temperature does not change during a phase change and am not entirely sure if I have accurately or thoroughly described 3. 2. 3 and 3. 2. 4. This is also the case for 3. 2. 12 Thermal Physics Thermal Concepts: Temperature (T) is a measure of how hot or cold an object is, and it is the temperature that determines the determines the direction of thermal energy transfer between two objects. It is a scalar quantity and is measure in degrees celcius ( °C ) or kelvin (K). 0  °C is equal to -273K.Kelvin is based on the properties of a gas. Thermal energy is the receiving of energy from a hot body by a cold body when placed next to each other. Internal energy of a substance is the total potential energy and random kinetic energy of the molecules of the substance. It is where molecules in a body gain energy internally and are able to be move faster (increased KE) and move apart (increased PE) from work being acted upon it. Moles: †¢ A mole of a ny material contains 6. 022? 10^23 atoms or molecules. This is also known as Avogadro's constant. However, all moles don't have the same mass due to the different types of particles which have different mass Thermal Properties of Matter: Specific Heat Capacity (C) of a material is the amount of heat required to raise the temperature of 1kg of the material by 1 °C. It is measured in J ?  °C / kg. It is expressed by the equation: c = Q/ m? T; where m is mass, Q is the quantity of heat and ? T is the change in temperature. Thermal Capacity (c) of a material is the amount of heat needed to raise the temperature by 1 °C.It is measured in J /  °C . It is expressed by the equation: C = Q/ ? T; where Q is the quantity of heat added and ? T is the amount of increase in temperature of a body. The physical difference between liquids, solids and gaseous phases in terms of molecular structure and particle motion involve atoms having KE and having strong attraction to each other when soli d and having both KE and PE with less attraction and more room to move around when liquid with even more PE and increased potential to move around when gaseous.Evaporation is the change of state of matter from a gas to liquid, whereas boiling is the change of state from liquid to a gas. Specific Latent Heat (L) of a material is the amount of heat required to change the state of 1kg of the material without change in temperature. It is measured in J / kg. It is expressed by the equation: L = Q/m; where Q is the amount of energy and m is the mass. Kinetic Model of an Ideal Gas: Pressure = force/area The assumptions of the kinetic model of an ideal gas are: †¢ The Molecules are perfectly elastic The Molecules are spheres †¢ The Molecules are identical †¢ There is no force between the molecules (excepting collision) with constant velocity between collisions. †¢ The molecules are very small Temperature is hence a measure of the average random kinetic energy of the mole cules of an ideal gas as the speed of particles increase as the temperature rises. Thermodynamics: Thermodynamics relates to a thermodynamic system – this is a collection of bodies that can do work on and exchange heat between each other. These laws apply to all systems. K is absolute zero temperature, where molecules do not move The equation of state for an ideal gas: PV = nRT; where n is the number of moles and R is the molar gas constant. A real gas molecule has a shape and a finite size, whereas an ideal gas molecule (imaginary) is a point with no shape and it occupies no space. A real gas molecule interacts with others. An ideal gas molecule reacts totally independent of all others. There are no ideal gas molecules, only real gas molecules. However, as pressure decreases and the temperature increases, real gas molecules act more like ideal gas molecules.Thermodynamic Processes: The expression for the work involved in a volume change of a gas at constant pressure: P? V; w here P is pressure and V is volume According to the law of conservation of energy, energy cannot be created or destroyed. Hence, the first law of thermodynamics basically states that as a gas expands and gets hot, heat must have been added: Q = ? U + W; where ? U is the increase in internal energy, W is the work done by the gas and Q is the amount of heat added to a gas. Examples of changes of state of an ideal gas: Isobaric (Constant pressure contraction) †¢ Isochoric/Isovolumetric (Constant volume increase in temperature) †¢ Isothermal expansion †¢ Adiabatic contraction The Second Law of Thermodynamics: The second law states that it is not possible to convert heat completely into work, implying that thermal energy cannot spontaneously transfer from a region of low temperature to a region of high temperature. Hence, it is about the spreading out of energy. Entropy: †¢ Entropy is used to quantify this second law. †¢ Entropy is expressed by the equation: ?S = Q/T; where ? S is change in entropy and Q/T is the quantity of heat flow into a body at a certain temperature. It is measured in J/ K †¢ The second law in terms of entropy changes states that in any thermodynamic process the total entropy always increases †¢ Even though locally entropy may decrease, the total entropy of a system will always increase. i. e. the stock in a fridge may get colder and the molecules become more ordered, with entropy in the fridge decreasing; however the total entropy of the room will increase and the room will gain heat.

Free Essays on The Starry Night

The Starry Night Anne Sexton poem The Starry Night reflects the Vincent von Gogh’s painting The Starry Night very well. If one was to do a little research into the lives of the writer and the artist they would find that they were kind of in the same path in life when they did these two works. Sexton mood in the poem matches the one in the painting. The two works have a lot in common and that could be because of the creator’s lifestyle. Van Gogh painting â€Å"The Starry Night was completed near the mental asylum of Saint-Remy, 13 months before Van Gogh's death† (online 1) and Sexton were depressed most of the time. Though there is not much information on Van Gogh’s life, we can see form Sexton’s life why she was inspired by this painting. She had tried to commit suicide a number of times because she was obviously not happy with her life. She was searching for comfort and when she could not find it in her parents she found it in her aunt who died later on and that made her more depressed. She was not happy in her marriage and had lots of affairs, and seeing therapist who encouraged her to continuing writhing. During her life she had tried to committed suicide on a number of ocasions and was finally successful in the end. In the poem she is viewing death as a serpent that swallows up the stars, she states that’s how she wants to die, for the life to just be sucked up with no cry. (1401). She was so depressed with life that she, judging from the poem, wants to disappear form everything. She dose not want to exist anymore. Wants to die a quiet and fast death. The painting it self is very depressing, but in a sense it’s kind of restful. The way that its restful is the little houses in the village they seem in a way really cozy and peaceful, while the sky is at war with it self. The one tree that’s there in the front is very dreary and dead and that makes it depressing. The poem is also depressing a peac...

5 Awesome Ways to Cut Your Energy Bills

5 Awesome Ways to Cut Your Energy Bills 5 Awesome Ways to Cut Your Energy Bills If you are moving into your first shared apartment, you’re probably worried about paying the bills. And since we are now into fall, you’re probably already thinking about turning the heating on. Here are some great ways for you and your housemates to save money! 1) Shrink Wrap Your Windows Did you know that shrink wrap makes an excellent substitute for extra window panes? If you are stuck with single glazed windows, you’ll know that the heat leaks out! Try taping shrink wrap to the window panes: you’ll be amazed at how much warmer your room feels! 2) Get Some Snakes! OK, real snakes probably won’t heat up your house much, especially since they are cold blooded. However, stuffed snakes laid at the bottom of doors, will! Try using the leg of an old pair of pantyhose and stuff it with rags. Put it at the bottom of your door and you have yourself a free draft excluder. For extra cuteness, add some googly eyes and a smile. 3) Line Your Curtains You’re probably thinking that this is the sort of thing your grandmother would do. But there’s a reason for that: it works! Add a fleecy lining to your curtain for extra insulation. 4) Reflect that Radiation! A sheet of aluminum foil behind a radiator reflects the heat waves back into the room, instead of letting it be absorbed into the wall. Bet you never thought foil could keep you warm, right? 5) Warm Up With Rice! Anyone who has ever tried studying with cold feet will know that it’s not a great experience. Sew up some raw rice in a rectangle of cloth to make yourself a microwaveable rice pillow. It uses a lot less energy than a hot water bottle (kettles are super energy intensive) and is ready in seconds. What are you waiting for? Get busy and make your home a warm and cozy study nest for the winter!

Tumour markers Essay Example | Topics and Well Written Essays - 1000 words

Tumour markers - Essay Example Therefore, it is important to understand that it is the quantity and not just the presence of these compounds that must be considered in assessing the clinical use of tumour markers. Tumour markers are usually proteins (structural proteins and enzymes), cell-surface carbohydrate antigens, cellular receptors, and genes, which are detected in tissue, urine, and blood samples. Markers can be specific for a certain type of cancer, while there are markers that are common for different cancer types. Some markers also show increased concentration in the tissues and body fluids even in the absence of cancers. Due to this, tumour markers by alone should not be used in to diagnose cancer. In an ideal situation, screening and early diagnosis of cancer are the major goals for using tumour markers. To be able to do this, a marker must be highly specific for a certain cancer. It must not come up with too many false positive results that could lead to unnecessary and expensive follow-up tests, not to mention the psychological effects that come with the possibility of having cancer. Markers levels should be elevated enough, and ideally can be used to screen asymptomatic individuals, meaning that they can be used to detect cancer early. However, because markers are present in low concentrations in the body, screening for asymptomatic individuals is only recommended for those who have a genetic predisposition towards getting cancer. Currently, only the Prostate Specific Antigen (PSA) has been recommended and approved for general screening of prostate cancer in men over 50. A positive screening result for PSA is still not an indication of cancer, and PSA screening should be d one in conjunction with a digital rectal examination of the prostate gland for diagnostic purposes. Markers are used to identify the local source of metastasized cancers, and could therefore aid in making a correct diagnosis. The recurrence of cancer can be checked by testing the levels of a
