Leadership Development Dissertation Example | Topics and Well Written Essays - 10500 words

Leadership Development - Dissertation Example Chapter 1 Introduction 1.1. Purpose of the study "Leadership development needs organization managers," Whilst in the past, as our research shows, most observers and experts had tended to view Leadership, and leadership development, as an independent area of consideration within the corporate structure, over the past two decades it has been increasingly seen to be an integral part of the total organization management system itself. Consequently, research often links the two areas together. There are an abundance of studies and research documents confirming this fact. These include that of Zaleznick (1977), who defined the leader as the person who brings about change, with the manager being the controller of those changes. Kotter (1990, p. 103) projected the view that "management is about coping with complexity. Leadership, by contrast is about coping with change". The purpose of this report is to examine the validity of the hypothesis. 1.2. Specific Objective This central objective of this report is to examine the opening hypothesis in order to arrive at a conclusion as to its validity and importance. 1.3. Delimitations For the purpose of this report, we have limited our study to the subject as it relates to a commercial organization, in preference to organizations in the public or charitable sector, although in reality the same principles would form the basis for measuring the successful future growth pattern for all of these structures. 1.4. Significance Our study covers the current thinking and research in respect of the leadership developments and its application in the corporate environment, including an analysis its importance and relevance. At the same time, we have reviewed and studied the research available regarding the... The literature will reveal how changes have occurred between these three elements, with the initial concept of management, which has been around since the early part of last century, is seen as the driving force behind the business. Later management was to lose its significance, giving way to the relatively new concept of leadership, with this taking a prominence in the thoughts of corporations and researchers alike. We will see how the views of business analysts and researchers for a period separated leadership and leadership development from management and conducted studies of these in these areas as almost diverse entities, emphasizing the differences between the two. For example, the School of Engineering and Electronics at the University of Edinburgh (1997), in their study on the subject, concluded that – â€Å"Managing and leading are two different ways of organizing people. The manager uses a formal, rational method whilst the leader uses passion and stirs emotions.† Dr. Paul Harborne (2001) and Stormy Friday (2002) within their respective papers also emphasized differences that exist between these conceptions, stressing the importance that this represented in business terms. However, more research has moved away from these theories, suggesting now that in fact, there is an interrelationship between the leadership and management, and that a competitive and successful business is best achieved in an environment where leadership development and the organization's managers work in partnership.

Obesity Essay Example | Topics and Well Written Essays - 750 words - 1

Obesity - Essay Example At the same time, demands of profession and education require the individual to be less-involved in quality food preparation in this age group with less free time available in contemporary society to seek appropriate exercise and fitness options. It is because of the lifestyles and risks in this age group that a health promotion activity to promote better eating and exercise is being proposed. The Research Findings The Centers for Disease Control (2012) indicates that approximately 25 percent of women between 20 and 30 are considered obese. Though this is significantly lower than other age groups with higher prevalence of obesity, it should be considered that the 20-30 year old age group in society is one of the lowest in terms of total national population percentages. Between 2009 and 2010, there was no reduction in obesity ratios in women, which illustrates that existing health promotion campaigns and other obesity initiatives are not meeting with the psycho-social characteristics prevalent with young females. Of this entire female age group, the majority of obese women are non-Hispanic black females, indicating that this particular ethnic sub-group of 20-30 year old women have unique lifestyle characteristics that contribute to obesity growth. Women between the ages of 20 and 30 are also in the population category that has the fastest increases in obesity compared to the rest of the national population. A study involving 555 women between 20 and 34 found that 63 percent of these women were obese as measured by the World Health Organization body mass index testing (Parrish, 2010). This study supports a finding which has identified that the type of foods purchased is strongly linked to income levels and the choices that women select related to their perceptions of health benefits. It is commonly known that younger females in this age category maintain unequal pay to their younger male peers in the professional organization and many are under-employed. Thus, it becomes more cost-effective for women between 20 and 30 to select cheaper food options congruent to their lower incomes in this particular age bracket. Contributions to the Program The CDC statistics illustrating that 25 percent of women between 20 and 30 being obese contributes highly to this program intention. By understanding just how many women are affected by obesity, it can help select an appropriate target audience and how best to establish an exercise routine that is effective based on lifestyle. The study involving such a high percentage of women being obese by Parrish (2010) acknowledges that obesity rates are significantly higher when measured against body mass index. Further, the linkage between incomes can provide new health imperatives to reduce this rapid phenomenon of weight gain and provide cost-effective solutions that are in-line with budget restraints for the younger female between 20 and 30. The goal of the program is to provide comprehensive knowledge about ex ercise and health lifestyles, which also includes food selections and preparation. It would be fundamentally defeating to the program to not identify the specific ethnic profiles and frequency of obesity within this group before selecting an appropriate strategy for combating this problem and improving young female health

Infectious Diseases: Causes, Effects and Treatments

Infectious Diseases: Causes, Effects and Treatments Introduction Infectious diseases or communicable diseases are those caused from pathological microorganisms including bacteria, viruses, fungi, parasites, prions, etc, which can spread from one person to another by direct or indirect means. Infectious diseases can also spread from animals to man or vice-versa (WHO, 2010). Throughout history, microorganisms, the causative organisms for infectious diseases have been playing an active role. Many native populations during the middle Ages have been destroyed by plagues. The Europeans when tried to conquer Australia, Africa and Americas had initially used microorganisms to destroy the native populations. However, the infectious diseases have had a serious effect on the fauna and flora. There were huge causes of morbidity and mortality, but in the 20th century developed nations had lower rates of morbidity and mortality from infectious diseases. The major reasons why there was control over the infectious diseases during the later part of the 20th centur y was due to the development of antibiotics, eradication of small pox through vaccination, improvement in the living conditions and sanitations, etc. However, in the developing nations, infectious diseases are a major cause of death. In the year 1993, about 51 million people died, out of which 16.4 million about 35% were from infectious diseases. In the sub-Saharan African regions about 70 % of the worldwide infectious disease deaths occur. Developed nations account for 10% of the worldwide infectious disease deaths (Wilson, 1995). Today, serious changes are made with the environment of the earth such that certain propulsions and groups are becoming vulnerable to certain infectious diseases. Not only have antibiotics made it easier to fight microorganisms but the abuse of the same has resulted in the microbes developing resistance. Besides, many insect vectors are becoming more and more resistant to various pesticides being used. Today there are several emerging infectious such Ebola, H1N1, H5N1, Lassa fever, etc, due to the changing environmental circumstances. In the year 1993, more than 400000 people from Milwaukee US were affected with the epidemic of cryptosporidiosis. In the Southwest people died from pulmonary disease caused due to Hantavirus infection. Not only are the humans affected with infectious diseases but also various other species of domesticated and wild animals (Wilson, 1995). With History, major changes have undergone with respect to the infectious disease map of the world. In the 20th century, many diseases have spread from tropical to temperate regions and have crossed marine barriers including the Atlantic and the Pacific Ocean. More than 14.2 million people each year die from infectious diseases. On the other hand, heart disease kills about 10 million people each year. The most common infectious disease killer is acute respiratory infectious with 3.7 million deaths each year, followed by HIV/AIDS with 2.8 million deaths, diarrheal group of diseases with 1.7 million deaths, malaria with 1 million deaths and measles with 0.8 million deaths. As sanitation and poor living conditions can increase the risk of infectious diseases, such problems are more common in the lower socioeconomic groups. The WHO has predicted that during the next ten years that infectious disease would reduce by about 3 % due to improvement in the living conditions (Bonita, 2006). In the ICD-9 Listing, codes 1 to 113 are given infectious and parasitic disease codes. It is found that about 83% of all deaths from infectious diseases are from range of symptoms outside the classical ICD mentioned criteria (Norman, 1998). With a number of infectious such as diphtheria, chicken pox, measles, feco-oral infections, cholera, rotavirus infection, etc, seasonal variations play a vital role, in the temperate and the tropical regions of the world. The mechanism by which this is occurring is not understood clearly. Certain reasons may be applicable for the seasonal variations of a disease:- Seasonability has several factors and a lot depends on local factors Depending on the characteristics of the infections epidemics or peak in incidences can occur at different times of the year There may be an interaction of pathogens that may affect the spread of another infection Hence, depending on these criteria vaccination can be used to block the spread of the infection (Nicholas C. Grassly, 2006). Infectious diseases may not just involve one person or a particular community or a population. Often more than one population may be affected across a region or a nation. Besides, infectious diseases can also affect animals including goats (Echinococcus), dogs (rabies), birds (H5N1), etc. Classification The listing of the ICD-9 Codes for Infectious diseases includes:- Intestinal Infectious Diseases 001 to 009 Tuberculosis 010 to 018 Zoonotic Bacterial Infectious 020 to 027 Other bacterial Infectious (such as leprosy, diphtheria, scarlet fever, etc) 030 to 041 HIV 042 to 044 Poliomyelitis, kuru, CJD, etc 045 to 049 Virus with exanthema 050 to 059 Arthropod borne virus infection 060 to 066 Other diseases caused by virus and Chlamydia (such as hepatitis A, B C, rabies, trachoma, warts, etc) 070 to 079 Rickettsia and other arthropod infections (080 to 088) Syphilis and other venereal diseases (gonorrhea, urethritis, etc) 090 to 099 Other Spirochete infections such as yaws, pinta, etc 100 to 104 Mycoses or fungal infectious 110 to 118 Helmenthic or worm infestation 120 to 129 Other infections 130 to 136 Late effects of infections 137 to 139 (ICD-9 codes) Transmission Infectious diseases are transmitted by two means, namely the direct and indirect means. Direct means includes contact with the infected person who comes in contact with the normal person. Through contact, infections can spread by three means, the first two include horizontal means and the third include vertical transmission. Infectious diseases usually spread by direct transfer of the infected fluids or secretions from one individual to another. There may be several means of person to person transmission including sharing infected needles, sexual contact, kissing, blood transfusion, sneezing, coughing, mucosa to mucosa, etc. Direct contact would also include contact with infected animals or handling contaminated animal wastes. The vertical transmission is by means of the infected mother to the baby. Infections again can be transmitted by different means at different periods. When the unborn baby is in the uterus, it can get infected from the mother. Certain infections can be transmit ted across the placenta and include bacteria (such as syphilis, listeriosis), viruses (such as CM Virus, AIDS, German measles), and protozoans (such as toxoplasmosis) (Lee Goldman, 2007). The effect on the fetus may range from fetal infections, lesions, mental retardation, physical growth retardation, multi-organ defects, birth defects, aborted, etc (Dorak, 2009). On the other hand, infection can spread to the baby during passage of the baby through the infected birth canal. Lastly, infection can spread through contaminated breast milk of the mother during nursing (Lee Goldman, 2007). Exposure to the infectious agents can result in various outcomes including no infection, clinical infection, sub-clinical infection or carrier status. Clinical infection can result death, carrier status and further immunity or no immunity against the disease. Sub-clinical infection can result in carrier status, immunity or no immunity against the disease (Dorak, 2009). Infectious diseases can also spread through indirect methods which include contaminated objects, personal items, food borne, waterborne, vector borne, air-borne, ting-borne and surfaces. For example, common cold can spread by using contaminated towels. Various bacterial, viral and parasitic infections can spread through vectors or carriers such as mosquitoes, fleas, lice, ticks, etc. Infectious diseases can also be transmitted from one individual to another through contaminated food or water or the oro-fecal route. Consuming uncooked, undercooked or raw foods, unsuitable drinking water, etc, can cause infectious. For example, in Latin America, there is evidence through PCR diagnostic tests that H. pylori cause gastric problems (Lee Goldman, 2007). Certain individuals may be at a higher risk of getting infected which includes those with autoimmune disorders, those who have undergone an organ transplant and are taking immunosuppressant, those consuming corticosteroids and those infected with HIV/AIDS. The other risk factors that play a role in the development of the infectious diseases may include age, race, sex, socioeconomic status, geo-location, medication use, illegal drug use, history of travel, etc (Sherwood, 2004). The mode of causation of an infectious disease is by an interaction of internal factors and environmental factors. An infection may arise as a result of a triad of factors affecting the system including the host, agent and the environment. The host factors include age, sex, gene-type, mental makeup, nutritional makeup, immune status, and health makeup. The environmental factors include air, water, sanitation, psychosocial status, geography, housing, food, healthcare delivery system, etc. The agent factors include pathogenicity of the organism (ability to cause disease), infectivity (ability to cause infection), virulence (ability to cause death), immunogenicity, survival and antigenic capabilities (Dorak, 2009). The entire natural cycle of the infection would ensure that the infectious agent is at the business end. The infectious agent would enter the host or reservoir and then exit from the body, carried by a mode of transmission and enter another persons body. It would result in infection in a susceptible host. Koch bought out certain postulates for infections. In each case, the organism is present. The organism can be isolated or grown in each culture. Once each individual is exposed to the agent, the disease as such can be reproduced. From each of the infected individuals, the pathogen can be isolated. Symptoms An individual suffering from an infectious disease may present with no symptoms, symptoms which are not definitive, mild symptoms, or serious symptoms with complications. The period between the exposure of the individual to the infectious organism and the appearance of the first symptom may vary from a few days (in the case of chicken pox, malaria, etc), months to a few years (in the case of HIV). Infectious disease can produce a range of symptoms including:- Fever Chills and rigors Bleeding of the gums and periodontal diseases Epistaxis Sore throat Anorexia Tiredness Body pain Dyspnea and breathing problems Headache Fever with seizures Swelling or a rash Malaise Enlargement of the regional lymph nodes along with tenderness Diarrhea and dysentery Bloody stools Yellowness of the skin and the tongue Paleness Skin lesions or skin rash Blood shot eyes (in the case of conjunctivitis) Burning sensation whilst passing urine Abscess or a draining sinus Pain, swelling from the affected site along with a rise in the temperature Gastritis Spread of the bacteria, along with the toxin in the blood Diagnosis The diagnosis of Infectious disease is made based on the history, physical examination, signs, symptoms, analysis of the tissue samples, microscopy, culture, blood tests, urine tests, molecular diagnosis and other methods. The history includes details of the personal history, history of travel, family history, social history, occupational history and epidemiology (Paul G. Engelkirk, 2007). Body samples of urine, CSF, nasal secretions, nasal swab, stools, etc are collected to study them microscopically. In certain circumstances water, soil, inanimate objects and food samples are also analyzed. In certain circumstances the samples are collected at a particular period of time. In malaria, the samples are collected when the fever is high and in the case of typhoid the blood samples are collected when the fever begins to rise. It is important to prevent contamination of the sample during testing and avoid any destruction of the causative organisms. It is important to transport the samples appropriately and test them immediately as many anaerobic species may not be able to survive in the oxygen-rich environment. Besides, it is also important to prevent drying of the samples. All samples should be given appropriate care during laboratory testing as they are hazardous and can infect the testing personnel (Barbara A. Bannister, 2000). There are different microscopes that can be used for studying the samples including light microscope, phase-contrast microscope, dark-field microscope, electron microscope, etc. Various staining procedures may be required to study the samples including gram staining, Giemsa staining, Ziehl-Nielsen staining, Indian Ink staining, etc. Helminthes, urine bacteria and fecal protozoan are best viewed through direct microscopy of unstained samples. Gram staining helps to identify organisms in pus, CSF, ascitis, pleural fluids, etc. Ziehl-Nielsen staining is used to study that will not stain through ordinary procedures. Romanowsky staining is used to stain blood cells, whereas Giemsa staining is used to identify the parasites present in blood. Immunofluorescence is a method of identifying the organisms through reactions with antibodies tagged with fluorescence dyes. There are two methods of immunofluorescence including direct and indirect methods (Barbara A. Bannister, 2000). Culturing involves growing the microorganisms present in the sample in the laboratory on an appropriate media and recognizing the same using physical, biochemical and morphological means. Different media may be used including enriched media, selective media and indicative media. Another process of distinguishing between the various strains of an organism is typing. These include biotyping, auxotyping, serotyping, phagetyping, PCR typing, etc (Barbara A. Bannister, 2000). Blood tests called as serological tests are done to determine the antigen-antibody reaction that occur. Some of the common tests that are done in the laboratory include agglutination, fluorescent antibody tests, radioimmunoassay and ELISA. Molecular methods of diagnosis are used to determine specific DNA fragments that would be a signature of certain species of pathogens. Some of the common molecular diagnostic techniques include PCR and amplification techniques (Barbara A. Bannister, 2000). Treatment One of the earliest ways of managing an infectious disease was in malaria when certain local communities used cinchona to treat the disease. From the cinchona bark, quinine was extracted and is used even today to manage malaria. Today, antimicrobial agents are being used to treat infectious disease. These microbial agents attack the various metabolic pathways that are present in the microbial metabolism. For example certain compounds are similar to PABA, and prevent PABA from undergoing transformation into dihydropteroic acid, which is essential for folate metabolism. Once there is shortage of folic acid in the body, the DNA of the bacteria undergoes degradation. Further other antimicrobial agents which target other portions of the metabolism can also be used for more effective treatment of infectious diseases. These include trimethoprin and sulphamethoxazole. The other ways by which antimicrobial agents act include causes the destruction of the bacterial cell wall, inhibition of the protein synthesis in bacteria, and damaging the DNA structure. For certain antimicrobial agents to act, the bacteria should be sensitive to the drug. Besides, the manner in which the drug is administered and the spectrum of action of the drug also plays a vital role in treating infections. Antimicrobial sensitivity tests are conducted to determine which particular agents the bacteria would be sensitive and resistant to and accordingly select a potent agent to treat the infection (Barbara A. Bannister, 2000). To ensure that the treatment with antibiotics is working properly certain monitoring strategies may be required including:- Appropriate levels of antibiotics are present in the serum The levels of antibiotics do not reach a level such that it would cause toxic effects Patient compliance and adherence Appropriate means of administration Pharmacokinetics of new drugs Monitoring all the adverse effects (dose-dependent or idiosyncratic) Some of the common groups of antimicrobial agents that are used to treat infections include:- Penicillin Penicillinase resistant penicillin Ampicillin-like agents Beta-lactamase inhibitors Cephalosporin Aminoglycosides Chloramphenicols Quinolones Antifungal Agents Antiviral agents Antimalarial agents Antitubercular drugs Antiprotozoan agents Prevention Infectious diseases are transmitted from one individual to another through several routes including direct contact, inhalation of airborne infections, consuming contaminated food or water, through vectors such as mosquitoes, ticks, etc, sexual contact, using contaminated personal items and through the mother-fetal route. Hence, prevention can be advocated by obstructing the means of transmission of the infection. One of the most important methods of prevention is by proper and frequent hygiene by handwashing and using a disinfecting soap. Immunization also plays a vital role in preventing infections by administering vaccines to the general populations. Vaccines are currently available for a number of bacterial and viral infections including meningococcal infections, hepatitis B, hepatitis A, polio, diphtheria, typhoid, tetanus, haemophilus influenza, chicken pox, rotavirus, human papilloma virus, H1N1, measles, mumps, rubella, etc. Passive immunization can be administered by the admi nistration of immunoglobulin. Zoonotic infections can be prevented by immunizing the pets, providing a clean and safe environment for the animals, washing hands before contacting animals, takes measures after animal bites, etc. At the workplace, transmission of infections are a risk because of the conditions and also because people are in close contact with each other and also with hazards. Needles, syringes and other biohazards need to be disposed off properly. Blood during donation and infusion should be appropriately screened for various blood-borne infections such as HIV, Hepatitis B, hepatitis C, syphilis, etc. Rubber gloves should be worn by the healthcare professional and for every new patient, a new set of sterile drugs should be selected. Hospital wastes should be disposed off properly to prevent hazardous wastes from further causing havoc (Andi L. Shane, 2008). Safe sex and sexual hygiene is also essential to prevent risk of transmission of STDs such as HIV, hepatitis B, etc. If there is the chance of the partner practicing unsafe sex, then a condom and other barriers help reduce the risk of transmission. Special precautions also need to be taken during travel. Areas infected with infectious diseases should be best not visited. For some people, vaccination may be required along with consumption of prophylactic antimicrobial agents (Andi L. Shane, 2008). Infectious Diseases in Saudi Arabia As in the rest of the world, in Saudi Arabia also, the morbidity and mortality from infectious diseases are high. An infection would have its course and severity varied depending on the virulence of the agent and the resistance of the host. Besides, a number of environmental factors also need to be considered. Two of the most common infections and serious health problems in the Western populations have been community-acquired pneumonia and fever of unknown origin (PUO). In the US, each year more than 1.3 million people get hospitalized from infectious diseases. The WHO has attributed Tuberculosis the most common cause of death in the world adult population. Certain factors may increase the risk for TB including HIV status, lower socioeconomic background, poor sanitation, etc. The other common infectious diseases throughout the world were hepatitis B, malaria and meningitis. Alghamdi found that the prior knowledge of prevalence and pattern of infectious diseases in the Western Saudi A rabian population was rather unknown and hence conducted this study to determine the most common infection in the hospitalized and determine their mean time of stay. More than 495 patients that were hospitalized between Jan 2000 to December 2004 at the King Abdulaziz University Hospital (KAUH) was studied. All data was collected from the patients medical records. About 8.8 % of the population who were admitted to the hospital or 1 in 11 were admitted for infectious diseases, and slightly more than 50% were males and 54% were native Saudis. Individuals between 26 to 45 years were commonly affected with infectious diseases, followed by the 13-25 year old group. The senior citizen population was least often affected with infectious disease. The most common infectious disease was pneumonia, followed by fever of unknown origin, TB, and viral hepatitis. In women, pneumonia was more common than men, whereas TB and meningitis were more common in men. The other common infectious in the population included bronchopneumonia, malaria and urinary tract infections (Aisha A. Alghamdi, 2009). The incidence of meningococcal meningitis is common in Hajj pilgrims and in the year 2000, several cases were reported in the Hajj pilgrims. The two common serogroups were serogroups A (24%) and W-135 (37%). The epidemiologists found that the Hajj Pilgrim 2000 Meningococcal attack was in fact two concurrent outbreaks. The W-135 serogroup is endemic in Saudi Arabia. The fatalities were high amongst the pilgrims and hence since the year 1987, mandatory vaccination was being introduced. The vaccine used in fact is quadrivalent in nature (Jairam R. Lingappa, 2003). The Tuberculosis statistics in Saudi Arabia were also alarming. In a study conducted by Sahal A. M. Al-Hajoj, 2006, it was found from about 1500 cases of Tuberculosis infection, that male-female ratio was 1.27 and 47% of the population being adults between the age groups of 21-40 years. The single drug resistant cases were about 19.7 % and the multi-drug resistant cases were about 47% (Sahal A. M. Al-Hajoj, 2006). Sahal A. M. Al-Hajoj (2009) conducted another study to find if the mortality and morbidity from tuberculosis could be decreased in Saudi Arabia. There was a rise in the number of cases of TB between 1990 and 2004 by about 6.2%. In Western Saudi Arabia, there is a huge influx of individuals from developing countries who may already be infected with Tuberculosis. The rise in tuberculosis cases may not only be due a rise in infection rate, but also due to better diagnosis techniques. Better TB programs and effective diagnostic laboratories are the need of the hour in controlling cases of tuberculosis in Saudi Arabia. There should also be greater uniformity across the country in standardization. In the year 2000, there was an epidemic of Rift Valley Fever in Saudi Arabia which had spread from the neighboring North African Region. About 886 patients were included in the study by Tariq A. Madan. The age group affected was the 40 to 50 year, and the male to female ratio was 4:1. The common symptoms recorded included fever, nausea, vomiting, abdominal pain, jaundice, diarrhea, neurological complications, bleeding, visual loss, liver function test abnormalities, leucopenia, renal failure, anemia, etc. There were about 14% mortalities from the disease and were often associated with bleeding, neurological symptoms and jaundice. People with leucopenia had a lower mortality than those who had a rise in the leukocyte count (Tariq A. Madan, 2000). In the year 2007, the first outbreak of H5N1 occurred in Saudi Arabia and affected 19 poultry farms. Several diagnostic tests were conducted to confirm the infection including Rapid antigen-capture test and real-time RT-PCR. Once the infection was identified in a particular town in Saudi Arabia, the government immediately made a decision destroy the H5N1 affected fleet and the non-affected birds in a radius of 5 kilometers and ensure quarantine measures were followed in the region so that the infection could be prevented from spreading to other regions. Besides, other measures were being adopted including closing bird markets, greater surveillance, quarantine, etc. Within a period of three months from the first detected cases, the epidemic was totally under control. Further within a period of three months (April 2008), Saudi Arabia was declared as H5N1-free (Huaguang Lu, 2009). In a study conducted by Abdulrahman A. Alrajhi (2004), the mode of transmission of HIV-1 was being studied. It was found that 46% were heterosexual transmission, 26% due to infected blood transfusion, 12% vertical transmission, 5% from homosexual activities and 2% due to use of contaminated syringes during IV drug usage. Most of the heterosexual men got infected from commercial sex workers, and about 65 women got infected from their husbands. In Saudi, the most rampant form of transmission of HIV-1 is heterosexual mode. The mean age of diagnosis of HIV in the 410 individuals who took part in the study was 27.8 years. The adult infection rate is about 0.01%. Women tend to get the infection from their spouses. The rate of infection was relative lower in homosexual men and IV Drug users (Abdulrahman A. Alrajhi, 2004). Thus it can be seen that infectious diseases are a serious problems. Some of the infections that are common in Saudi Arabia include pneumonia, Fever of unknown origin, tuberculosis, meningitis, HIV, acute viral hepatitis, chronic viral hepatitis, malaria, etc. Besides, outbreaks of several emerging infections are becoming commoner in Saudi. These include the Rift Valley Fever of 2000, H5N1 outbreak of 2007, dengue fever, viral hemorrhagic fever, multi-drug resistant tuberculosis, etc. Many of the zoonotic infectious are getting transmitted to man by vectors such as ticks and mosquitoes (Tariq A. Madani, 2004). The mechanism of development and the transmission of such infections need to be studied.

To Kill A Mocking Bird :: To Kill a Mockingbird Essays

To Kill a Mockingbird Usually, my method of writing a book review starts off with a quote. However, this time with this particular book I’ve decided to begin with a description of the author. Harper Lee was born on April 28, 1926. She studied law along with her father and sister. In her allegorical novel, To Kill a Mockingbird, Harper Lee writes about a young girl in a small southern town by showing the difficulties she will have to face as she grows up.   Ã‚  Ã‚  Ã‚  Ã‚  The author’s purpose is to show us how life isn’t always fair. I strongly agree with her on that for several reasons. For example, look at what happened to Tom Robinson. He was accused of a crime he didn’t commit and then he was killed because someone was lonely. She got him in trouble, which drove him to his death. In this example, life is definitely not fair because he never should have been accused of something he did not do. I could give several examples of smaller, less important situations that have the same theme as this story does â€Å"do not harm people who do not harm you.†   Ã‚  Ã‚  Ã‚  Ã‚  The setting of this book was in Maycomb, Alabama in the 1930’s. Scout, Jem and Dill spend the summer trying to get Boo Radley out of his house. None of them had ever seen him. Scout started to school and on his way there and back, he and Jem would find gifts in a hole in the tree by the rocky place. Scout and Jem started hearing their father referred to as a â€Å"nigger-lover† because he was defending Tom Robinson – a Negro man accused of rape. When Scout, Jem and Calpurnia come home from church, they find Aunt Alexandrea is staying with them for the trial. One night, Atticus mysteriously leaves the house. Scout, Jem, Dill follow him. A lynch mob appears and was trying to force Atticus to let them have the Negro prisoner, but then the kids show up. On the way back from a Halloween pageant, the children were attacked by someone and caused Jem a broken arm.   Ã‚  Ã‚  Ã‚  Ã‚  During the book, Scout changes a lot. She goes from being an immature young girl to a mature young lady. She had a lot to adjust to in this story. For example, Jem felt her was older and too old to hang out with his little sister.

Barriers to Critical Thinking Essay

Identify 3 barriers that influence your critical thinking and write at least 100 words for each, describing how you can overcome them. Barrier 1: The first barrier that influences my critical thinking is reliance on main stream television, newspapers, and other media for information. I feel this is a barrier many people have, especially in today’s society where it is very easy to upload something to the internet or how easy it is to edit information found on the internet. I am an avid user of google, however I have an issue with differentiating between what is actually true and not true in what I read. Some people believe everything they read on the internet is true, therefore being a barrier, and that is clearly not the case. In order to avoid this ignorance and to overcome this barrier we need to do our own research, check the reliability of our sources, and to use more sources than just one, i.e. internet, different websites, news stations, and newspapers, not solely rely on just one source. Barrier 2: The second barrier that influences my critical thinking is lack of relevant background information or ignorance. Without enough information it is hard to be a critical thinker, have thoughts on the matter, or base your opinion. With a lack of information you do not have the whole story, therefore having a gap in your critical thinking. An example of how lack of information could be a barrier is: you got into an argument with your sibling, your sibling told you parents their side, and without even hearing your side they had their decision made about what happened and the punishment. I feel that would prevent them from being able to critically think about it due to having a lack of background information, they only had one side of the story. To overcome this we can try to not rely only on the first thing you hear and to do our research and ask questions when needed to gather more information.

Ethical Arguments for Wal-Mart

Wal-Mart went public in October of 1970. Their IPO was 3,000 shares at a price of $16. 50 per share. By having a smart business model and keeping cost low though a variety of tactics including low employees wages and benefits, Wal-Mart has been able to sustain an incredible rate of growth. Since their IPO Wal-Mart has undergone eleven full 2-1 stock splits. That means that just one share of their IPO has turned into 2,048 current shares. The current market value of Wal-Mart stocks on the NYSE is $62. 0 per share. If an investor bought just one share in 1970 for $16. 50, today that investment would be worth $127,590. 40. In addition to rising stock value, investors receive a quarterly cash dividend payment that was paid out at $0. 2725 per share as of July 2009. People start and invest in businesses to make money.
