The Effects of Postural Changes, Exercise and Cognitive Stress on Essay

The Effects of Postural Changes, Exercise and Cognitive Stress on Human Arterial Pressure and Pulse Rate - Essay Example High blood pressure turns out to be silent killer which many people fail to detect, since it does not have any easily identifiable symptoms. The Circulatory System, which plays a major part in coronary health, functions mainly in the transportation of blood carrying nutrients and oxygen to all parts of the body. However, the Circulatory System is subjected to various pathological conditions. Pathological conditions may result from the abnormality of any component or processes in the Circulatory System. Heart disease results when coronary blood vessels are damaged and cannot provide adequate circulation of blood to the supporting cardiac muscles and tissues, thereby affecting the overall functionality of the systemic arterial blood pressure. According to the World Health Organization, 17 million people die of Cardiovascular Diseases (CVDs) including strokes and heart attacks annually (WHO, 2011). High blood pressure, specifically, has been identified as a major risk factor for most CV Ds and therefore, it should be monitored. The primary importance of studying the components and the processes of the circulatory system is to understand the relationship between the functions and the structures, and for proper diagnosis of the diseases affecting the Circulatory System. Normal blood pressure (BP) is generated when the blood flows through the arterial blood vessels. During systolic contraction, blood pressure peaks at 120 mmHg and drops to 70 or 80 mmHg during the diastolic phase. Essentially, blood pressure can be used as an indicator for abnormalities in processes or in structures within the Circulatory System. For example, changes in the elasticity of the arterial walls as in the case of arteriosclerosis can be identified by the increase in pulse pressure; however, it is the mean arterial pressure (MAP) that is important clinically. MAP is the main pressure that drives blood for systemic circulation. It is regulated to ensure that sufficient amount of blood is prop elled to the tissues, but the pressure would not be high enough to cause extra workload for the heart. As the blood passes through the arterial walls, the arteries expand to accommodate the amount of blood pumped by the heart.  

The Alarming Increase of Children Diagnosed with Autism Essay

The Alarming Increase of Children Diagnosed with Autism - Essay Example What is autism? Recognized a half century ago (Hanchette), Autism is a developmental disorder that has been deemed very severe and begins anytime between the birth of the child and 2 Â ½ years of age. These children are normal in appearance, but they will engage in various disturbing behaviors that are obviously different than the behaviors of normal children. There are also varying degrees of autism. Those who have less severe cases may be diagnosed with Pervasive Developmental Disorder (PDD) or Asperger’s Syndrome in which the child may have normal speech, but display some social and behavioral problems that are associated with autism (unknown, autism.com/autism). But believe it or not, it was once believed that autism was to be accepted as is because it was thought that nothing could be done about it. But now there have been a variety of treatment methods developed which have proven to be very helpful in leading to great improvement. Yet there is also the unfortunate fact that some treatments may have little or no effect at all on the autistic child (unknown, autism.com/autism). So why was autism thought to be hopeless? Well, for many years autism was thought to be a very rare occurrence. The average number of children born with autism was 5 out of every 10,000 live births (unknown, autism.com/autism). But since the 1990’s, there has been a very noticeable rise in the number of children developing autism. This rise is telling us that there is an average of 60 children out of 10,000 born with autism in which boys outnumber the girls four to one. As of 2007, the Centers for Disease Control reported that 1 in 150 children are diagnosed with autism (unknown, autism.com/autism). To think that in 1992 there were only 2,800 kids with autism in the entire state of California. When 2002 rolled around, that number had increased to 20,400 and as of 2004, the number of autistic children in California reached a staggering 24,000. That is a 440% increase between the years 1994 and 2004. New York is up 200% in the last decade and Pennsylvania has reached a 900% incr ease (Hanchette). It is very obvious with the latest statistics that autism is undergoing a significant rise, which makes it very important that the behavioral and physical signs are recognized as early as possible to ensure the appropriate treatment is administered. It is said that the sooner the child is treated, the better the outcome. With increased awareness of the signs and treatment being administered early, there are autistic children attending regular classrooms and some can live somewhat independently in a community setting. However, autistic people do not lose the impairment that comes along with autism that affects their ability to communicate and socialize successfully. This aspect, unfortunately, continues to haunt them for the duration of their lives. Behavioral signs of autism There are various behavioral signs associated with autism. These signs include: repetitive behaviors, lack of speech, withdrawal from parents or siblings, very little or no social interaction (Hanchette). If the child displays no big smiles or other expressions of joy by six months old, then that is a huge red flag. Another sign is if they do not share facial expressions, sounds or smiles, or if the child has not spoken by 16 months or has used multiple worded phrases with meaning by 24 months, those could all be

Consumer Buying Behavior Assignment Example | Topics and Well Written Essays - 750 words

Consumer Buying Behavior - Assignment Example This involves a detailed study of how buyers think and behave during purchase situations, and what factors may influence their tastes and preference towards certain brands. Consumer buying behaviour is, therefore, the study of the ways of buying and disposing of goods, services, ideas or experiences by individuals, groups, and organizations in order to satisfy their needs and wants (Kotler & Hibbard, 2014). Alternatively, consumer buying behaviour â€Å"refers to the buying behaviour of final consumers, both individuals and households, who buy goods and services for personal consumption† (Hibbard, 2014,). This occurs when the consumer is immensely involved in the purchase process, and there are notable contrasts amongst the brands to acquire. This implies that the consumer has to conduct research about the product/service and the marketers must, therefore, supply all-inclusive information with regards to product/service characteristics. A medical example, in this case, is when a hospital wants to acquire medical equipment such as x-ray machines for the hospital. The hospital’s procurement officer (consumer) is highly involved because of th e significant financial involvement (high risk) in the acquisition, and the unfamiliarity with the commodity. There are many brands according to manufacturers (about 75 suppliers) and they are used for different purposes. This compounded with the fact that they have different price tags makes the consumer very sceptical. He must, therefore, conduct thorough research to eliminate brands that do not suit the hospital’s need requirements and fit his budget plan respectively. Here, consumer participation, while acquiring the product/service, is low, and there are noteworthy contrasts between the brands. The consumers attempt to find variations in products or services. Thus, the marketers must rally the market to buy their commodities through means such as promotions, publicity and advertising. A medical example, in this case, includes medical cosmetics for products like toothpaste.

Ethical use of information technology - Article Example Federal Intelligence Organization and for shattering the integrity and privacy of the U.S. Air Force website (Chellel 1). In May 2013, they were jailed as these reputable organizations suffered with hefty losses of reputation and money due to these hackers. In jail, Ackroyd was truly guilty and felt extremely embarrassed for what he did and how badly he used his gifted skills (Chellel 1). He decided to correct all his mistakes when he gets out of jail, and use his natural blessing of ability to hack for the goodwill of his nation and people. But, he was still doubtful if life would give him another chance and he would get any opportunity to be a part of the respectable society and study further, ever. Ackroyd’s imprisonment period was shortened to nine months. When he was released out of jail in February, his good intentions helped him and he succeeded in getting admission at Sheffield Hallam for a Masters qualification in the field of Information Systems Security (Chellel 1). It was not late after, when he again got a big chance to prove his skills, but now for a good purpose. His role became active when companies direly demanded ethical hacking, due to flooding in of cyber security. Companies lacked the immediate expertise required to protect their business from drowning in the floods of cyber security. LulzSec’s hacking activities against Pay Pal and Mastercard Inc. were observed at a hype when they rejected WikiLeaks to operate for their payments from their platform. These companies got highly alert when Wikileaks dispatched all military confidential information. LelzSec’s members conducted their activity by recording FBI conversations, uploading all secret info and false claims on YouTube. They became a great threat for the nation. Ackroyd has a heroic role in this act. Server obstacles and hidden patterns were always a thrill for Ackroyd (Chellel 1). With his nature of taking the hidden as a challenge and going deep down, Ackroyd

Marijuana Coursework Example | Topics and Well Written Essays - 1000 words

Marijuana - Coursework Example and the government must take marijuana treatment interventions seriously. What exactly is this drug and how has it become so prevalent, especially among the youth? What are the negative effects of this drug, and the positive effects if there are any? What method of treatment best addresses the condition of those who are addicted to this drug? This paper will attempt to answer these questions and shed light on the identified issues. According to a report quoted by Michael Lyman, 57 percent of adults aged 19-28 have reported using Marijuana in their lifetimes. (2011: 116). It comes from the leaves of the cannabis tops and is dried and smoked from a pipe, as one does a cigarette. If the experts are to be believed, marijuana has several negative effects. An important one is the loss of cell energy leading to cell death, especially when it saturates the cell membrane and blocks the passage of vital nutrients. Another research finding shows that marijuana usage affects the part of the brai n that deals with motivation in general, it has also been found that marijuana is bad for both the mind and the body. Although there is no such thing as a lethal overdose of marijuana, i.e., no one has ever died of ingesting too much (of course, if a marijuana user drives or operates heavy equipment, then the disorientation can cause him to injure himself), its long term effects can seriously impair a user’s health.. Lyman also points out that the toxins and cancer-causing ingredients in the substance leads users to feel the same health issues as those who smoke cigarettes, such as bronchitis, emphysema and bronchial asthma. But aside from that, there are also halluncinations, behavioural changes, apathy, loss of motivation because of the effects to the nervous systems, thus making it worse than cigarettes. He further says that: Some of the effects of marijuana use also include increased heart rate, dryness of the mouth, reddening of the eyes, impaired motor skills and concen tration, and hunger with an increased desire for sweets. Extended use increases risk to the lungs and reproductive system as well as suppression of the immune system. But are there health benefits to marijuana? There are those who argue that marijuana has beneficial effects and can even serve as medical treatment, particularly for glaucoma. According to Kuhn, et. al. (2008: 165), there are reports that those suffering from multiple sclerosis and other disorders having to do with impaired muscle control have responded positively to marijuana treatments. At present, however, the debates are still raging on whether or not marijuana can be made a mainstream drug. The negative effects of addiction still far outweigh the potential medical benefits. In any case, for those illnesses that are said to be curable with marijuana, there are other less-controversial treatment options available. But what are the treatment options available for those who are suffering from marijuana dependence? The most viable treatment option is abstinence and withdrawal, because marijuana is not as addictive as other drugs and those who have grown dependent on it can kick the habit more easily than if they were addicted to drugs such as cocaine or

Social Responsibility Essay Example | Topics and Well Written Essays - 250 words - 1

Social Responsibility - Essay Example Social responsibility works to the best interest of the society. In other words, social responsibility seeks to promote social welfare subject to the decisions and actions taken by business enterprises. The underlying welfare is defined in terms of social impacts that result from the daily business activities of many and different enterprises. The business fraternity is expected to play a moral and ethical role in developing the society as they progress with their daily activities. This implies that part of their success and benefit should be channeled to the society. Essentially, the three primary factors that social responsibility accounts for include the economy, environment and society (Allen, 2011). The growth, development, and sustainability of these three factors encompass the role of social responsibility. Any enterprise operating in the societal setting needs to consider the economic, environmental, and social implications of its activities. The ultimate objective of social responsibility is to ensure that enterprises do not adversely affect the society. On the same note, the new venture is factored in the process to ensure that social responsibility is realized. The new venture, therefore, drives social

Personal Statements Essay Example for Free

Personal Statements Essay Thinking about humanity nowadays and peoples preoccupations made me realize the huge impact that crimes and criminal justice have on their decisions and the way they receive and react at the details and information about a crime. Television news, newspapers and magazines, they all speak about crimes, unsolved criminal problems or strange disappearances. The worlds evolution, its issues have pushed societies nowadays to extreme gestures to escape from poverty problems. Why do people commit crimes? How much crime is there committed around us? Which would be the profile of a criminal and which would be his or her characteristics? Moreover, how could these crimes is stopped? I have been attracted to criminology since the early age of just 12. I was watching Discovery channel series like Deadly women†, â€Å"Life of a crime, Most evil and I was fascinated by the way those people were investigating and solving those crimes helped by only some fragile and minor details. As time passed by, I realized that this was my hobby and so I started thinking how I could develop my skills for a career in criminology. I thought that if I entered an exact sciences high school profile, I would constantly keep my mind focused, as subjects like mathematics or informatics enlarge your vision. As criminology implies psychology, I was and I am still interested in this fascinating subject. I will always be interested in discovering the characteristics of human nature. I had contact for the first time with Psychology in the second year of high school. I also read very interesting books about psychology and criminology such as Psychology and Crime Myths and reality, by Peter Ainsworth, Criminology, by John Conklin, etc, describing its characteristics and feeding my curiosity. I have discovered myself a lot of skills after reading those books and this was an extra reason for me to attend to a Criminology course. Besides criminology, I also like IT (information technology). As technology occupies a significant part of our lives, I thought it would be helpful to certificate my skills: I obtained my OCP certificate for ORACLE sql database course; I attended the ECDL (European Computer Driving Licence) courses from where I got a diploma as a complete operator of the Microsoft Office package. At present, I am attending the ORACLE pl_sql programming course which I am going to finalise in May 2009 and obtain my certificate. Even though I have been focusing on my ambitious plans and my future, I havent forgotten the ones that werent so lucky when speaking about familys kindness and warmth. So, I was involved myself in volunteer projects every Christmas and Easter. The volunteer action is called National Strategy The Community Action. In present, I intended a new strategy to help the mentally or physically affected children at the Orizont Center in my town, Constanta. In my opinion, abandoning you own child is a crime and if he or she has a handicap it is ten times worse. As I am a very active person, I also took part to a lot of extracurricular activities, like: general-knowledge quizzes, chemistry contests where I have participated with the project Water crystals. Crystal therapy and gained two prizes, I am part of the high school volleyball team with which I won a lot of regional and national competitions, I had a job as an IT operator for introducing and validating dates within the POL-RENAV company, etc. Considering the fact that criminology is my hobby (terrorism, youth crimes, homicide, violence in crimes), it would be the perfect course for me to study and improve at university. Studying the behavior of criminals or investigating their crimes will always create a challenging future and an interesting one, having always something new to learn. As a personal conviction, criminology is maybe the most complex job that one could want: it involves mental strength, devotion and 100% interest for this field. 2. For a number of years I have had more than a passing interest in Criminology, Psychology and Sociology; in particular Criminal Psychology, Neuropsychology, the nature versus nurture debate and the Criminal Justice System. Additionally, I hold equal interest in the research, both past and present, undertaken to develop theories and concepts in the Social Science fields. I would now like to pursue these interests at a higher academic level with the hope, upon completion of my study, to gain employment whereby I could effectively utilise the skills and knowledge I had obtained, possibly in the research field. The reasons behind my late entry into higher education are primarily due to immaturity and lack of direction. Throughout my teens and early twenties my life was unconventional; this is where I believe my interest in the working of the human mind and sociological influences stem from. I have reflected on the contributing factors that led me to make the choices I made during my adole scent years. For me this raises the question of whether the underlying causes were biological or socially influenced or even a mixture of the two. Over the years I have matured and gained a sense of direction regarding what I would like to do. In 1999, I decided I wanted to contribute to my local community by doing some form of voluntary work, in particular with those who suffer from mental health problems. I became a befriended through Hilling don Mind. A befrienderÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s role is to support a person who is feeling isolated from the community. Every week I would visit my friend and sit and chat and lend an ear, we would also enjoy trips out into the community. I enjoyed my 12 months working as a befriended; I found it a humbling, fulfilling and rewarding experience. Sadly I had to make the difficult decision to leave the Hilling don Mind Befriending Scheme in the later part of 2000 due to unforeseen increased family and work commitments. In early 2006, I made the decision to return to education. As I had not been in full time education for 21 years, I chose to ease myself back into the system by studying a Horticulture course part time over a period of 2 years. I completed this course in July 2008 passing with 6 straight Distinctions at level 2; completing this course was the catalyst to further my education it gave me the confidence required to progress further. In September 2008, I enrolled on an Access to Psychology and Social Studies course and an additional GCSE Moths course at level 2. I am finding my current course both exciting and thought provoking and am enjoying life as a student immensely. My hopes are that on completion of both these courses I will have acquired a solid foundation of Social Sciences and the skills required to study at University. Throughout my life I have experienced a variety of roles within the work force including care work, administrative roles, production line work and voluntary research work for several websites. I have raised my two daughters, 5 17, almost single handed for the last 8 years; the eldest of which is in her final year of a levels and is currently in the process of applying to universities. For a number of years I have successfully maintained 2 Allotments, although they require a great deal of physical work I find growing my own produce extremely satisfying. Additionally, I enjoy listening to a variety of music and reading, in particular non-fictional crime. I manage my ongoing commitments to my children, education and allotments extremely well, indicative of conviction, dedication and good time management skills. Law with Criminology Personal Statement Social development within the country is based around the well-structured judicial system; however, this fundamental principle is not true for all countries and therefore permits shocking injustices to be carried out on the most vulnerable members of a society. It is from this that I believe my interest in Law stems. I am a keen, ambitious, diligent student and always strive to reach the best I can in whatever I do. Studying A levels in Business Studies, English Language and Biology gives me broad knowledge of different topics from which I have acquired many valuable skills that I believe can assist my studies in Law. Business Studies has been particularly useful when developing my understanding of the financial world and ever-changing business laws. Applying and examining bureaucracy and red tape to set case studies, has encouraged me to research further into the world of consumer rights and explore what is acceptable and not. I have enjoyed studying Biology and having to work close ly as a team when completing practical experiments with precision. English Language has given me the opportunity to analyse written texts which will be an advantage when studying cases and having to pick out key information. Studying AS Psychology has encouraged me to examine how criminal minds work and whether particular events from earlier years of life can have an effect. Recently, I attended a Foundation Degree Law Course where the idea was to become a Lawyer for the week and develop the learning skills required for University. During the week I had hands on experience and undertook many legal practices such as taking witness statements and drafting statements of case. I found the course thoroughly enjoyable, particularly offering legal advice, and it helped me to realise how Law influences everyday decisions and activities. I have contributed too many different aspects of school life ranging from playing in successful musical concerts to becoming a senior student as a Year 8 mentor for which I had to attend two peer mediation courses. From this I learnt how to enhance my listening skills and empathise with those around me, offering reliable advice at the same time. I believe this would assist me when recommending legal advice to clientele. Along with a small group of other students, I am currently helping to set up a Committee to improve Sixth Form Life. Although this is to be carried out alongside my lessons, it helps me to plan my time well who benefits my studies when completing coursework and other various set tasks. The Young Enterprise Scheme, where it was our job to set up a company and assign ourselves roles within it, was a good insight into having to work as a team and understand business laws. I was chosen as the company secretary as I had the organizational skills which were necessary, this meant I had to work closely with the Managing Director to discuss issues and then make sure that every employee understood the tasks set. This developed my interpersonal skills as I had to liaise between staff, students and visitors from external companies. Personal well being is something I value and so participate regularly in exercise, giving me a sense of achievement when I overcome a certain obstacle or beat a personnel target. At school, this reflects my self discipline approach to studying. I have had to institute a system of time management alongside my education as I work part-time twice a week at South Deep Cafe. Working there for three years has, primarily, made me particularly approachable, as I have learnt many valuable customer relation skills, but has also reflected my trustworthiness and commitment especially when training other employees. As an enthusiastic, well-rounded, dedicated student, I feel I have the attributes and genuine passion needed to succeed on a Law Course, and look forward to the many challenges and aspects of life at University. Law and Criminology/Sociology Personal Statement From a young age, I have been fascinated by law and was thrilled at the possibility of studying it at A-Level. In August 2007, I was able to spend two weeks working at Naves Solicitors in Lupton. Most of my time was spent in the Conveyancing department, where Andrew Orriss, a partner in the firm, taught me how to draw up commercial leases and business contracts, and about buying, selling and renting residential properties. I most enjoyed meeting clients and discussing their cases. I found that moving house many times as a child enabled me to be sympathetic and relate to the clients. My time at Neves has made me more intent on pursuing a career in the law, as I liked the work and fitted in well with the staff. I believe my current studies of Law, English Language and History complement each other well and would give me an advantage at university, as they have furthered my strong reading and writing abilities, and taught me to be more logical and investigative. I also took Religious Studies at AS-level as I like learning about other peoples beliefs, and it helped me to become more open-minded. I enjoy getting involved with activities in my Sixth Form, such as planning the Summer Ball in Year 12. I was chosen by our Deputy Head Girl to take the minutes for the meetings and email them to the other committee members, and my minutes were commended by my Head of Year. I was also asked to assist with the Sixth Form Induction Evening. My duties involved welcoming prospective students and their parents, handing out prospectuses, and talking to them about my own experiences of Sixth Form. In Year 13, I was chosen as a History subject mentor to help struggling Year 12 students, and I also helped out on a trip to Germany with students in years 7 to 9. Outside of school, my hobbies include photography, bass guitar, and writing. In 2006, I came second in a BBC writing competition for young people in Northamptonshire. Having grown up in France, I am bilingual, and my next challenge is to write a short story in French. I also have a part-time job at McDonalds, which has taught me about working with others, as well as coping with pressure. One of the crucial parts of my job is ensuring that customers are satisfied, and occasionally dealing with complaints. I believe the people skills I have gained from McDonalds will help me in other aspects of my life. I regularly attend my local church and Christian youth group. In July 2007, I had the opportunity to go to Kosovo for a fortnight with other members of the youth group. Our aim was to help widows and orphans affected by the Yugoslav Civil War and the ethnic cleansing of Kosovans in 1999. We redecorated homes and schools, ran childrens clubs, distributed aid, and visited a Roma gypsy camp. It was a very profound and moving experience, and one I hope to repeat at some point in the future. This is the reason for my deferred entry to university. I plan to spend a few months fundraising, and then return to Kosovo for the remainder of the year to continue the work we started there. I believe that I am a confident and enthusiastic person who would benefit greatly from studying at university. I am passionate about the law and would like to have a career as a lawyer. I also have a keen sense of justice and an interest in Sociology and Criminology and would consider working with the Prison Service or the CPS. I think that studying Law at university would help me make the best possible use of my analytical and writing skills, and that a career in Law would satisfy my need to help.
