...Epidemiology Paper: Mononucleosis Naomi R. Walsh Grand Canyon University: NRS-427V January 25, 2014 Epidemiology Paper: Mononucleosis Mononucleosis (mono) is most commonly known as the kissing disease. Mono usually occurs in adolescents and young adults. The virus that causes mono is carried in saliva and passed though such activities as kissing, coughing, sneezing, and sharing of cups and eating utensils. Mono is not a fatal disease, but it can cause weeks of uncomfortable symptoms. Although there is no cure for mono, there are many type of therapies that can help to alleviate some of the symptoms. (Mayo Clinic Staff, 2012) Description and Demographic Mononucleosis is a disease caused by one of the most common human viruses in the world, the Epstein-Barr virus (EBV). According to the University of Maryland Medical Center, “mono effects about 45 of 100,000 people, mostly teens and young adults” (University of Maryland Medical Center, 2013). A person with mono is contagious for several days before symptoms begin to appear and for some time after. The virus is spread through saliva by kissing, sharing drinks and food, sharing cups and utensils, sharing toothbrushes, and sharing toys that have drool on them. Many people are infected with the virus and have no symptoms; those that do suffer symptoms are usually teens and young adults. Once the virus is picked up it has an incubation period of four to six weeks (Mayo Clinic Staff, 2012) . The most common symptoms...

...The following question appeared in paper 2 of the June 2015 additional examination (actual question number 4.3): Drug-testing kits are sometimes used in schools. The current drug test which uses blood or urine samples is considered to be too personal (invasive). A new drug test, the Saliva Drug Test (SDT), uses saliva and is considered to be less personal than the current test. It can be used to test for up to 9 different types of drugs. The pictures below show the drug-testing instrument and the swab used to take a sample of saliva. The tree diagram below shows the outcomes of the SDT after testing the saliva of the same person twice. Study the tree diagram above to answer the following questions. 1.

...Work Place Drug Screening Opinion Paper Miquavian Tate PSY/425 January 14th, 2016 Sherrell Ellis Workplace Drug Screening Opinion Paper In today's society drugs are have become more prevalent that any other time in the past. Due to the rise in drug use, employers have begun to take more steps in testing potential candidates before they make the decision to hire them. Although these drug tests do not show potential addictions to alcohol, they take the chance of hiring someone who abuses drugs out of the picture. There are many tests available to these employers to choose. This paper will cover the type of test available, what's the kind of programs are offered to those who abuse drugs and give a general summary of both ethical and legal issues surrounding drug testing in the workplace (Hartwell, 1996). There are five types of drug tests that employers can choose. These five tests are consist of urinalysis, blood testing, hair testing, saliva, and sweat testing. The most common form of drug testing used during pre-employment is urinalysis. Urinalysis is the most popular with companies because of how little the cost is and how easy it is to administer on of these test. Although there are low costing and easy, these test can easily be tampered with by the recipients of the test by drinking large amounts of water pretest to dilute the urine to make the sample untestable. Another problem that may arise is that of a possibility of error with the test at the lab which they...

...Research Paper: The Harmful Effects of Cell Phones There are many reasons why people are concerned that cell phones might have the potential to cause harm physically and emotionally. Physical problems include certain types of cancer or other major health problems. However, one of three main factors that has researchers worried is that cell phones emit radio frequency energy (radio waves), a form of non-ionizing radiation. Another main concern about cell phone usage is the rapid increase of the device over a small period of time. Also as technology and cell phones increase, the quality of relationships have decreased because of the emotional attachment felt toward it. The biggest issue in using cellular devices is the radiation that the devices give off and the uncertainty if it is harmful or not. When looking at radiation, there are two types. One is Ionizing radiation (IR) – which is capable of causing changes in atoms or molecules in the body that can result in tissue damage such as cancer. Examples of ionizing radiation include x-rays, microwaves and gamma rays. The second one is non-ionizing radiation (NIR) – which doesn’t cause these changes, but can prompt molecules to vibrate. This can lead to rises in temperature, as well as other effects. Examples of non-ionizing radiation include ultraviolet radiation in sunlight, visible light, light bulbs, infrared radiation, microwave energy and radiofrequency energy. For example, RF radiation from a mobile phone has the biological...

...Classical Conditioning Paper PSY 390 September 19, 2011 Chelsea Hansen Classical Conditioning Paper The primary premise of psychology is the study of one’s behavior through mental research as well as physical experiments. Classical Conditioning is the study of one’s behavior through research and experiments and trying to identify the conditions one put themselves in or are put in to study their behavior. “Classical Conditioning is a technique used in behavioral training.” (http://psychology.about.com/od/cindex/g/classcond.htm) A Russian physiologist by the name of Ivan Pavlov is believed to be the igniter to classical conditioning though his intense research and experiments with dogs and his saliva theoretical presentations and experiments. Pavlov also believed that “classical conditioning is a learning process that occurs through associations between an environmental stimulus and a naturally occurring stimulus.” (http://psychology.about.com/od/behavioralpsychology/a/classcond.htm) Theory of Classical Conditioning and Scenario The theory of classical conditioning that was most famous by Ivan Pavlov was the digestive system where he then accidently had his attention drawn to “psychic reflexes.” (http://www.learning-theories.com/classical-conditioning-pavlov.html) The scenario that will be used in this paper will be how prisoners are classically conditioned with “chow time” (time to eat) in the prison system. In the prison systems inmates and their natural reflex of...

...When a person says, “sixty-five roses,” one would think that they literally mean sixty-five roses, but in reality they are talking about one of the most life threatening diseases – cystic fibrosis. While this nickname may seem like it has some dark history behind it, it actually does not. The story behind this is that in 1965, Mary G. Weiss, a volunteer for the Cystic Fibrosis Foundation, was making calls about financial support for CF research because her three little boys had CF. After she had made several calls, her little boy, Richard, told his mother that he knew who she was working for. Having no knowledge that he even had Cystic Fibrosis, he told his mother that she was working for 65 Roses. Since 1965, the term “65 Roses” has been used...

...invisible ink are lemon juice and milk. Write on paper with a fountain pen, toothpick or a finger dipped in the liquid. Once dry, the paper appears blank. The writing is made to appear by heating the paper, on a hot radiator for example. Invisible inks have been used for secrecy and security for many years. The Germans in World War II used invisible inks for secret writings. One suspected spy was found to have large numbers of keys in his motel room. After inspecting the keys it was found that some of the keys were modified to unscrew at the top to show a plastic nib. The keys contained special chemicals for invisible ink! However, codes and secret ink messages were very easily captured and decoded. Some of the more fun secret writings are concealment messages like invisible inks made out of potato juice, lemon juice, and other types of juices and sugars! Deciphering and decoding messages take a lot of time and can be very frustrating. With experience, strategies, and most of all luck, you'll be able to crack lots of codes and ciphers. | Information Gathering: Gather information about your project.

...Properly reared men and women will always answer the phone with enthusiasm; they will convey to the caller their appreciation for placing the call; they will stand up to express authority. This will inculcate further self-confidence in one’s voice. Think and Write When the body and mind remain cohesive, extraordinary thoughts and ideas will appear. Therefore, retain each one by jotting them in a personal recorder or on paper. When enough accumulation has taken place, put them all in a central reviewing location for further study. In paraphrasing Oliver Wendell Homes: “When the minds of men and women explore profound personal ideas, their brains will swell never to regain their original proportion. Value Good Habits Proper habits remain crucial for surviving catastrophic disaster deployment. Such conditioned behaviors will strongly discipline the mind to overcome dangerous situations. Otherwise, the mind will falter when overwhelming death and dying images of men, women and children become re-imagined.

...neural and behavioural mechanisms and as such, a central question of human history. Children with aggressive behaviour form a heterogeneous population in relation to certain subtypes of aggressive antisocial behaviour. Callous-unemotional traits (e.g. absence of emotions and blame) are well-studied and temperamentally tied in with acute and persistent antisocial expression in children, which holds the risk for progressing psychopathy later in life (Frick & Viding, 2009) Serotonin levels are thought to contribute to childhood aggressive and antisocial behaviour, which can lead to expression later in adulthood (Raine, 2002). Thus, genetic factors are an inseparable part of the nature of antisocial behaviour, as demonstrated by twin research that has shown that heritability is likely to determine various forms of aggression and personality factors, such as impulsivity and callous-unemotional traits (Moffitt, 2005). Despite the fact that the specific genetic basis of the innate nature of antisocial behaviour has not been firmly demonstrated, a number of studies have proposed that serotonergic dysfunction acts as a trigger for deviant behaviour (Cadoret, Langbehn, Caspers, Troughton, Yucuis, Sandhu & Philibert, 2003). In their study Cadoret et al consider various factors which remain significantly important in...

...Hepatitis B is a global health problem, it is a liver infection that can cause serious complications and is potentially life threatening arising from the Hepatitis B virus (HBV). This paper will provide an overview of hepatitis B, including demographic information, determinants of health, the epidemiological triangle, the role of the community health nurse and a national organization that addresses the communicable disease. Hepatitis B is an infection of the liver caused by HBV; the infection can be classified as acute or chronic (Daniel, 2014). An individual with acute hepatitis infection may not exhibit symptoms and are unaware they may be carrying the HBV. During this time, individuals infected with the virus may pass the virus on to others, symptoms do not persist longer than two to three weeks, it is considered short term. Normal liver function returns in four to six months. Symptoms include loss of appetite, nausea and vomiting, low-grade fever, tenderness to right upper quadrant, jaundice, fatigue, muscle and joint aches and pain (Daniel, 2014). Tests performed will be positive for the hepatitis B virus, which are HBsAg+, HBc-IgM and HBe-antigen. The HBV is transmitted when the virus enters the bloodstream through breaks in the skin, the mouth and genitalia areas. Examples include unprotected sex, exposure to needle sticks, skin punctures (skin piercing, tattoos, acupuncture) and sharing personal items that are contaminated (www.cdc.gov). Healthy adults with...
