The Effects of Antidepressants on children and Teenagers essays

The Effects of Antidepressants on children and Teenagers essays Sara is a twenty two year old Caucasian female. Sara was diagnosed with HIV seven years ago, but recently started antiretroviral therapy when her viral load went over 100,000 and her T cell count dropped below 140. She began on a triple combination therapy regimen including two reverse transcriptase inhibitor and a protease inhibitor. There are three main points that are necessary to discuss, in order to have an understanding of the true killer that AIDS is. Firstly, we must address the history of the killer and how it operates. Next, I would like to acknowledge theories of where the virus originates and how it came to infect so many people. Finally the last task is to really get a grasp on how many people the virus affects, and what modern day scientists are discovering in new methods of treatment. Starting from the beginning, AIDS, or Acquired Immune-Deficiency Syndrome was discovered in the early 1980s. It was originally called GRID, Gay Related Immune disorder. Homosexual white males near the New York and California coast were becoming infected with mysterious illnesses and tumors. According to previous instances, these strains of microorganisms were rarely serious or combined in the same individual. One of these infectious agents was called Pneumocystis Carinii a usually inactive or harmless organism. P Carinii usually infects us at a young age. Although it has been known to cause fevers and infections that can sometimes be fatal, these are rare instances when the immune system is sick because of malnutrition or other forms of abnormal weakness. It was later discovered that the cause of these mysterious illnesses was HIV, Human immunodeficiency virus. HIV is not new to the world there is a similar equivalency in the primate world called SIV, Simian immunodeficiency virus. This virus has long affected certain African apes and monkeys, however it causes no immunodeficiency in its hosts or disease. It is harmless to them, but...

Set Theory and How It Is Used

Set Theory and How It Is Used Set theory is a fundamental concept throughout all of mathematics.  This branch of mathematics forms a foundation for other topics.   Intuitively a set is a collection of objects, which are called elements. Although this seems like a simple idea, it has some far-reaching consequences.   Elements The elements of a set can really be anything – numbers, states, cars, people or even other sets are all possibilities for elements. Just about anything that can be collected together may be used to form a set, though there are some things we need to be careful about. Equal Sets Elements of a set are either in a set or not in a set. We may describe a set by a defining property, or we may list the elements in the set. The order that they are listed is not important. So the sets {1, 2, 3} and {1, 3, 2} are equal sets, because they both contain the same elements. Two Special Sets Two sets deserve special mention. The first is the universal set, typically denoted U. This set is all of the elements that we may choose from. This set may be different from one setting to the next. For example, one universal set may be the set of real numbers whereas for another problem the universal set may be the whole numbers {0, 1, 2,...}.   The other set that requires some attention is called the empty set. The empty set is the unique set is the set with no elements. We can write this as { } and denote this set by the symbol ∅. Subsets and the Power Set A collection of some of the elements of a set A is called a subset of A. We say that A is a subset of B if and only if every element of A is also an element of B. If there are a finite number n of elements in a set, then there are a total of 2n subsets of A. This collection of all of the subsets of A is a set that is called the power set of A. Set Operations Just as we can perform operations such as addition - on two numbers to obtain a new number, set theory operations are used to form a set from two other sets. There are a number of operations, but nearly all are composed from the following three operations: Union – A union signifies a bringing together. The union of the sets A and B consists of the elements that are in either A or B.Intersection - An intersection is where two things meet. The intersection of the sets A and B consists of the elements that in both A and B.Complement - The complement of the set A consists of all of the elements in the universal set that are not elements of A. Venn Diagrams One tool that is helpful in depicting the relationship between different sets is called a Venn diagram.  A rectangle represents the universal set for our problem.  Each set is represented with a circle.  If the circles overlap with one another, then this illustrates the intersection of our two sets.   Applications of Set Theory Set theory is used throughout mathematics. It is used as a foundation for many subfields of mathematics. In the areas pertaining to statistics, it is particularly used in probability. Much of the concepts in probability are derived from the consequences of set theory. Indeed, one way to state the axioms of probability involves set theory.

Anthropogenic climate change and its effects Research Paper

Anthropogenic climate change and its effects - Research Paper Example Despite the fact, that many European and Western countries have ensured strict measures against growing population yet many Asian, African and Latin American countries in the world have failed to understand the same (DiMento & Doughman, 2007). Despite the fact that these people present great opportunities for the nations in form of young working people, youth, which is full of energy, and contribute to overall economic growth of country; however, on a global basis, every human is brining with himself the potential to create more pollution and climatic damage to the planet earth (Hansjurgens & Antes, 2008). As mentioned earlier that this is one of the toughest choices because by restricting their populations these underdeveloped countries will put a brake on their future development and growth since without work force the same would not be possible. However, in order to ensure that the planet is face, it is important to undertake this decision (Bulkeley & Betsill, 2005). One of the bi ggest sources of pollution and climatic change has its roots in the greed of humankind in electricity generation, which not only disturb the atmosphere of earth but also disturbs the land as well. We are quickly running out of the world’s fuel resources and our hunger of exploring more fuels and consuming them is creating more pollutants and dangerous gases (Hoffman & Woody, 2008). Therefore, another decision would be to use solar energy all over the world to meet the energy requirements of the planet. Estimates indicate that the total energy which can be created by all of sun rays that are aimed at our planet in 24 hours are more than enough to meet the energy requirements of this planet for more than an year (Letcher, 2009). However, for implementing the same many countries will have to divert their funds from other developmental and non-developmental expenses to the creation, manufacturing, and use of solar energy systems (Hansjurgens & Antes, 2008). Furthermore, like the United States and other Western countries, these countries will have to ensure that tax exemptions and other economic measures are taken to pursue people for buying these solar energy panels. Furthermore, it may also require the planning and design of buildings and houses in such a way that they could install these panels on their roofs. In addition, this would also mean that the percentage of new skyscrapers would decrease significantly (Nelson & International Food Policy Research Institute 2009). Rather than building new mega cities, industries and others, nations will have to invest their fortunes in building and growing forests. It will have to give back to this planet what it has taken from the planet. Humankind has cut down billions of trees on this planet for the past couple of centuries to make room for its own buildings, cities and other mega structures. However, this is has created a serious misbalance in the overall atmosphere and ecosystems. By stopping the progress and growth of industries and planting trees instead, nations would be able to play their part in saving the planet (Hoffman & Woody, 2008). Plastic bags pose the biggest threat in terms of environmental degradation. These

The Dangers of Police Work Research Paper Example | Topics and Well Written Essays - 1500 words

The Dangers of Police Work - Research Paper Example Most frequently, they respond to ‘unknown disturbances or problems’ whereby a person may be asking for help but the police officer does not actually know what he/she is to expect or he/she is not able to gather more information regarding the situation (Dempsey & Forst, 2007). The duties of police officers involve operating in various kinds of circumstances, with much of their work being outdoors walking the beats assigned to them or riding in patrol cars. Their work is deemed extraordinarily dangerous – while carrying out their duties, some police officers are wounded or even killed. Police work can entail horrid tasks, which expose them to dangerous, sordid or depressing situations. They may be required to deal with all kinds of people in diverse situations. These dangers are usually traumatic for the police officers as well as their family members. Generally, police work holds the potential for the unpredicted and the unknown, and most individuals who take on this job possess a strong commitment and passion for it. Police work may involve being on duty 24 hours a day – even when not on call, the law requires a police officer to respond to criminal activity or to emergencies, during which no consideration is made for time of day or night o r even weather conditions (Ferguson, 2007). Gaines and Miller (2007) explain that the dangers of police work are both physical and mental/psychological. They indicate that according to the United States’ Justice Department policing is one of the most dangerous jobs in the US with 261 of every 1000 officers’ targets of non-fatal violence annually. Between the year 2003 and 2004, over three hundred police officers were murdered in the line of duty. They further assert that police work, in addition to physical dangers, involves considerable mental stress and pressure. The United States’ Bureau of Labor Statistics indicates that together with being a surgeon, firefighting, driving a taxi,

The Project DB Essay Example for Free

The Project DB Essay Project Planning entails a lot of complexities most especially when the project at hand is quite complicated and limited in nature particularly in time constraints. Nevertheless, there are specific tools designed to facilitate manageable and easy project planning possible. Such tools may be classified according to the nature of the project handled. For small to medium sized projects, tools such as Gantt Charts, Critical Path Analysis, Program Evaluation Technique (PERT), and Planning Cycle may be used. While planning large projects may employ the use of the tools such as Planning Management Methodologies, Stakeholder Analysis, and Stakeholder Management.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Among these, the commonly used are the Gantt Charts, Critical Path Analysis, and PERT. All these three requires Work Breakdown Structure. Gantt chart (designed by Henry Gantt) is very useful in the sense that it is much easier to construct and understand. The activity in relationship to time is immediately obvious unlike the other tools. Its value is easily recognized as it is less complex to look at. While Critical Path Analysis or CPM and PERT are both powerful tools, the first one identifies which tasks should be done on time to complete the project on time, at the same time, identifies which tasks can afford to have delay yet still completing the project on time. Thus, CPM identifies the shortest possible time to complete the project, the resources needed, and the most efficient way of shortening the time. PERT is a slight modification on CPM. It makes use of quite skeptical view of time for each project stage. The optimistic, pessimistic, and most likely time is indeed helpful to prevent biases from unrealistically short time-scales assumptions. Hence, in my own point of view, I personally prefer to use CPM since it has a lot of advantages over the others considering that it can present the early and late completion of the project with respect to the time allotted to complete the project.    Works Cited Page    Project Planning Management Tools. 15 July 2008.

The Definition of Insanity as it Relates to Criminal Offences :: Criminal Justice

The insanity defense is a defense asserted by an accused in a criminal prosecution to avoid liability for the commission of a crime because, at the time of the crime, the person did not appreciate the nature or quality or wrongfulness of the acts. The insanity defense is used by criminal defendants. The most common variation is cognitive insanity. Under the test for cognitive insanity, a defendant must have been so impaired by a mental disease or defect at the time of the act that he or she did not know the nature or quality of the act, or, if the defendant did know the nature or quality of the act, he or she did not know that the act was wrong. The vast majority of states allow criminal defendants to invoke the cognitive insanity defense. Another form of the insanity defense is volitional insanity, or Irresistible Impulse. A defense of irresistible impulse asserts that the defendant, although able to distinguish right from wrong at the time of the act, suffered from a mental disease or defect that made him or her incapable of controlling her or his actions. This defense is common in crimes of vengeance. For example, suppose that a child has been brutally assaulted. If an otherwise conscientious and law-abiding mother shoots the perpetrator, the mother may argue that she was so enraged that she became mentally ill and incapable of exerting self-control. Very few states allow the volitional insanity defense. The insanity defense should not be confused with Incompetency. Persons who are incompetent to stand trial are held in a mental institution until they are considered capable of participating in the proceedings.The insanity defense also should be kept separate from issues concerning mental retardation. The U.S. Supreme Court ruled in 2002 in Atkins v. Virginia, 536 U.S. 304, 122 S. Ct. 2242, 153 L. Ed. 2d 335 (2002) that the execution of mentally retarded criminals constituted "cruel and unusual punishment" and that it was prohibited by Eighth Amendment. But if a person is acquitted by reason of insanity, execution is not an option. The insanity defense reflects the generally accepted notion that persons who cannot appreciate the consequences of their actions should not be punished for criminal acts. Most states regulate the defense with statutes, but a few states allow the courts to craft the rules for its proper use. Generally, the defense is available to a criminal defendant if the judge instructs the jury that it may consider whether the defendant was insane when the crime was committed.

Hollow of the Three Hills Essay

Themes of the Hollow of the three Hills: -main character as a beautiful woman with a shameful and abominable past. -trying to run from it will only make the problem follow. -character as someone who is a plighted subject who had such a secret that she had to be where â€Å"no mortal could observe them. -She wanted this witch to help her see and hear what was happening with her loved ones; but she only had one hour to do so and after this one hour she would die Hawthorne did not come out and said this but in saying things like â€Å"there is but a short hour that we may tarry here. and I will do your bidding though I did . She had run from everything that was important to her because the most important, was dying. Hawthorne was not too clear in stating what exactly the problem was but it seemed that her daughter had fallen ill. – Throughout the story Hawthorne masks this fact well and uses foreshadowing nicely. In one part where the main character is looking in on her parents by means of the witches powers and Hawthorne describes her parents as speaking †¦of a daughter, a wanderer they -Not only she had left him with pain and suffering for their child but she had also left him with pain and aversion towards her. She tried to run away from her daughter’s sickness and encroaching death, but by doing so only brought guilt and remorse upon herself. She must have known that her husband would have strong feelings of antipathy towards her and still willingly looked in on his life to see how he was. – The part in the story when she looked back towards her husband was the part of the story that stuck out the most as Nathaniel Hawthorne’s style of writing. This was a good example of his ‘Puritan Guilt Ethic’. She felt such remorse for leaving that the only good thing to do was to check up on him and see if he was all right. Nathaniel Hawthorne uses the ‘Puritan Guilt Ethic’ in most of his short stories and novels and this is one example of him using it. – The daughter died of her illness as Hawthorne foreshadowed throughout the short story by writing such things as â€Å"into the tone of a death bell and â€Å"like lamplight on the wall of a sepulchre. The main character left her daughter to die and that is just what happened. Looking back in retrospect the main character probably would have stayed with her daughter. -As a mother watching her daughter’s funeral brigade must have broken her heart but watching it through a witches spell must have shattered it. –  Hawthorne’s main character chose to run like a coward and in the end paid the worst consequence of all. She gave up her life to witness the pain and suffering she had cause to others. With her daughter dead by disease, her husband infuriated with hatred and pain, and her parents filled with disgust and humiliation she had no one that cared about her at all because she couldn’t handle the emotional stress. How much emotional stress does it seem she caused to others in the end though? She tried to escape her duties as a wife and mother but they just followed her to the very end
