Why Soft Drink Industry Is Profitable Essay Example for Free

Why Soft Drink Industry Is Profitable Essay 1. Why was the soft drink industry so profitable? Soft drink industry observed growth rate from its inception 1886 to 1990, the consumption of soft drinks saw remarkable growth, below data shows the growth in United State’s consumption. Year| 1899| 1970| 1980| 1990| Consumption| 0. 6| 22. 7| 34. 5| 47. 4| #Consumption: Gallons per person per year Financial figures also back the growth story of the Soft Drink market. ROE %| 1972| 1975| 1980| 1981| 1982| 1983| 1984| 1985| 1986| 1987| 1988| 1989| 1990| Coke| 22| 21| 20| 21| 18| 19| 23| 24| 27| 29| 31| 49| 36| Pepsi| 16| 18| 20| 20| 14| 17| 12| 30| 22| 24| 24| 23| 22|. ROE is even higher across years and it increased to 36% for Coke and 22% for Pepsi in 1990 from 22% and 16% in 1972 respectively. The main reason for being profitable is that the United States market took the soft drinks overwhelmingly and gradually it became a part of their life style also the manufacturing process for concentrate was simple and required small investment, significant cost were to advertise, promotion, market research etc, while bottling process was extremely capital-intensive and involved specialized, high speed lines, but there was no considerable investments required on Advertisements, promotions and market research etc. This way Concentrate Manufacturers and Bottlers complemented each other for higher profit margins by sharing cost on in procurement, production, marketing and distribution. Many of their functions overlap; for instance, Concentrate Manufacturers do some bottling, and bottlers conduct many promotional activities. Balance Sheet data for year 1986 shows that pretax profit as % of assets was $. 40 per case for Concentrate Producers and $. 37 for Bottlers. The Cola war between Coke and Pepsi played significant role to increase the consumer base as both came up with new strategies and ideas to grab the market share from others that resulted to new markets and new consumers.

Use of Lidocaine and Sodium Thiopental for Pain Management

Use of Lidocaine and Sodium Thiopental for Pain Management Different premedication admixture with propofol to attenuate pain severityinduced by propofol injection: a double blind randomized controlled clinical trial Abstract Background and Objective Propofol has widely used due to providing pleasant anesthesia and rapid recovery. However; injection pain is one of the main side effects of a propofol that has remained as an undesirable problem. This study compares the effect of thiopental, lidocaine, fentanyl , normal saline admixture with propofol compared with only propofol on injection pain induced by propofol Materials and methods A double blind randomized controlled clinical trial was conducted on 257 patients that were randomly allocated to one of five groups to receive only 2mg/kg of Propofol type Fresenius One percent in group I, 2 cc of Lidocaine 1% in group II, 2 ml of Normal Saline 0.09% in group III, 50 mg Sodium Thiopental in Group IV and Group V were injected 100Â µg Fentanyl before injection of Propofol. Verbal Rating Scale was used for assessing pain. Results A significant decrease in pain severity during injection was achieved in group II (lidocaine ) and IV (Thiopental) compared to other groups. Fentanyl was also effective in reducing moderate pain. Conclusion: We found that Thiopental and lidocaine reduce more effectively incidence and pain severity than other groups. It seems that aforementioned drugs bee more appropriate as an alternative method to diminish propofol injection pain than others treatment in this study. Key Word: propofol, injection pain, premedication Introduction Preoperative care cause satisfaction for patient in recent years(1)Propofol is the drug that has attained popularity which has widely used owing to its fast onset time ,short-acting duration , and trivial adverse effects (2) despite these favorable attributes, the prevalence of injection pain has been reported 68-90% and has been ranked seventh among the 33 undesirable clinical problem in anesthesia(3-6). Injection pain severity was reported 5.6 Â ± 2.3 by measuring system of Visual Analog Scale , which represents unfavorable pain (7). Up to now, different ways have been studied and recommended to reduce the incidence and pain severity of Propofol injection. Among various methods, emollient of Propofol (8, 9) and using numerous drugs including Lidocaine (10), Thiopental(11) ,Alfentanil (12) and Gransytron or Ondansetron(13)can be noted. There are different emollients of Propofol in Iran such as Fresenius Propofol 1% which has a side branch of a long triglyceride (LCT) and Lipuro Pro pofol 1% which has side branches of medium and long triglyceride (MCT/LCT) ,that is assuming that later one is more effective in reducing injection pain(14). Lidocaine as a local anesthetic inhibits the beginning and conduction of nervous impulses by decreasing the penetration of nerve membrane to Na+. It prevents the membrane depolarization, effluence and conduction of potential . It’s systemic absorption is rapid via skin and phlegm (throat, respiratory system) (15).Fentanyl is a drug which usually used as a premedication, because of the rapid and short onset, intense analgesia, Stable cardiovascular hemodynamic as well as less histamine release (16). Thiopental from barbiturate family causes hypotension but has a high ability to protect nerves and control ICP (17). Ondansetron is a modern antiemetic drug which is chosen as the antagonist of Hydroxyl Triptamin type 3. This drug reduces nausea and vomiting and its complications are also very low(18). Different advantages of aforementioned drugs for pain persuaded us to use them to understand that how much they can reduce propofol injection pain and which one is more effective. Methods: A double blind randomized controlled clinical trial was performed on 257 patients, after obtaining confirmation from both Golestan University of medical science and 5th Azar hospital ethical committee approval. Signed written consent was taken from all subjects before surgery. Including criteria were patient aged between 15 to 55 years old with ASA ÃŽâ„¢, ΙΙ (American Society Anesthesiologist) that candidated for elective surgery, such as bowel obstruction, hernia, laparatomy , during 1390 to 5th Azar educational hospital in Gorgan, northeast of Iran. Alcohol consumption or taking any pain medication during 24 hours before surgery, a history of neurological disease, chronic pain syndrome, thrombofelebit, advanced systemic disease (such as advanced diabetes), and any contraindication based on injection of Propofol led to patient withdrawal from the study. Measuring patients pain using VRS (Verbal Rating Scale) from zero to three which has been developed by MC Hunter and Crirrick. Detail shown in (table 1). After patient’s entering into the operation room ,a No. 20 cannula were inserted in the biggest vein in no dominate hand. (without injection of a local anesthetic) and was connected to normal saline solution (without start of infusion). Difference between the two independent proportion formula calculated 24 samples for each group, however, considering five groups in our study, adjusted for sampling (19) was calculated, (= = 2*24 = 48 48*5= 245 ) g assume as the number of groups that 245 samples calculated. To achieve as s ame power as parametric tests we also used the efficiency power of nonparametric test, so that the sample size was multiplied by inverse 95 percent (20)which finally 260 samples was considered. Simple randomization allocation method was used to assign patients into five groups, so that five envelopes which containing the name of drugs was prepared and one out of five randomly selected for a patient and this approach repeated for all patients. In the first group (53 patients) 2mg/kg of Propofol type Fresenius One percent (MCT/LCT) was injected. In the second group (50 patients), 2 cc of Lidocaine 1% before use of Propofol was injected . The third group (48 patients), received 2 ml of normal saline 0.09% before the injection of Propofol .Group IV (54 patients) 50 mg Sodium Thiopental before injection of Propofol type Fresenius was injected. Group V (55 patients) also received 100Â µg Fentanyl before injection of Propofol. The place of injection is the dorsal vein of the hand. None of the patients received premedication and they were asked about the pain in injection place, 5-10 seconds after injection of 25% of anesthetic induction dose. And it was inscribed in questionnaire and after lessening the level of patients’ consciousness the rest of the anesthetics were injected. Anesthesia method were be same in all patients. The Propofol we wanted to use kept at room temperature (21 centigrade). Patients and the anesthesia nurse who filled out the questionnaires won’t know about the injected solution. And there is no chance to distinguish the solutions because they had the same color, volume and also the same shape. The first anesthesia nurse prepared the medication and injected by the second anesthesia nurse, the measure of pain and discomfort in hand examined by third anesthesia nurses and the questionnaire filled out by the fourth anesthesia nurse .To determine the relationship between premeditation and a measure of the pain Mann-Whitney and Kruskal- Walis test was used and demographic feature was also compared using ANOVA and Chi Square test with Spss 11.5. Results 257 out of a total 260 participated patients were analyzed in our study and 3 cases due to lack of condition were exclude. Characteristic of study subject including age, gender, weight and ASA physical status were presented in table2. No statistically significant difference saw in demographic characteristics of all groups and were comparable. (Table 2)(p>0.05)The overall and detailed of pain incidence shown for all groups in (table 3).Pain intensity at propofol injection in lidocaine and thiopental groups was much lower than three other groups especially in severe pain however fentanyl were also better than normal saline combined with propofol and using propofol only. No patient experienced spo2 less than 95% and heart rate lower than 50/min. No complication and adverse effect (eg, pain, allergic reaction, inflammation, edema, wheal ) were observed at the injection location 24 h after surgery. There was no conflict of interest . Discussion Pain during propofol injection causes anxiety and can interfere an appropriate anesthesia. Pain during Propofol injection mechanism is not well known yet, But it is suggested that perhaps a direct stimulating effect causes the immediate feeling of pain, or an indirect effect dependent on mediators release lead to begin pain.(15) dilatory pain (after 10 to 20 seconds) results from an indirect effect on the endothelium owing to the release of Cyanogens(21). Fat-soluble causes the increased activity of plasma’s kallikrein-kini system that leads to production of bradykinin. These interactions cause dilation and increased permeability in the peripheral veins, lead to an increase in Aqueous phase of Propofol with the endothelium and free efferent nerve endings between the media and intima of vessel wall and eventually cause pain (22). Finally we can say Propofol is a kind of drugs which stimulate skin, phlegm and inner vein wall(23). Gozal and Freeman (24-26) have debated, confined area size between the endothelium and drug is more influential than absolute drug concentration. A various method such as temperature(27) dilution(28) concurrent use of drugs(29-31) , give a variety to speed injection(32) has been used to attenuate propofol injection pain but different lidokaine dose and technique mostly use to attenuate for such pain (33)Analgesia results of Lidocaine in pain reduction following Propofol injection is not only because of it’s local analgesia but also it causes the decrease in Propofol Ph, and according to a hypothesis, Ph decrease causes Propofol moving into lipid phase and decrease Propofol in Aqueous phase and therefore lead to decreasing pain.(34, 35). In the present study, injection of Lidocaine before Propofol injection leading reduction in pain that the findings are compatible with other studies (23, 26, 36) but with the exception that their doses which were more than ours. Nevertheless controversy still exists (37) maybe for using higher dose in our study . The effect of Sodium Thiopental in pain reduction was accorded with other s tudies (8, 35, 38, 39). Fentanyl is also diminishes such pain but not as much as lidocaine and thiopental that is consistent in diminishing pain with others investigations (40-42) Conclusion This study finding shows that use of Lidocaine and Sodium Thiopental in comparison with other medications cause more reduction in pain especially in severe pains but lidocaine is more available cheaper than thiopental . Although no significant observed between some groups in pain reduction but pay attention to our founding in frequency of pain suggest using propofol with any premedication even normal saline better than injected propofol alone.

Effect of Blast Loading On a Person Protected By Body Armour

Effect of Blast Loading On a Person Protected By Body Armour Executive Summary The ballistic threat has been presented to military forces for hundreds of years in one form or another, from spears to bomb fragmentation. A lot of work has gone into countering this ballistic threat and the protection currently provided is very good. The standards of body armour ballistic testing is rigorous. Due to the modern asymmetric battlefield that modern military personnel now face, the threat has evolved. More often, the personnel are being subjected to blast from improvised explosive devices emplaced by irregular forces. This paper will review the some of the research that has been carried out into the effects of blast loading on a person protected by body armour. British Army studies show there was a higher incidence of primary blast injury in fatally injured soldiers wearing body armour that in civilian bystanders (Committee on Testing of Body Armor Materials for Use by the U.S. Army 2012) involved in IED incidents in Northern Ireland. This paper will explore the effects of blast loading on a person wearing body armour. Introduction. Soft body armour is designed primarily to protect the wearer from the most dangerous battlefield threat, projectiles, and fragmentation, with the 3 main testing standards for body armour (NIJ (U.S. Department of Justice 2008), HOSDB (Croft Longhurst 2007) and STANAG 2911 (North Atlantic Treaty Organization 2015)) only specifying testing criteria for ballistic protection. Due to the increasing use of improvised explosive devices (IEDs) in modern asymmetric warfare, there is a growing risk of personnel being subjected to blast associated injuries (Tranchemontagne 2016). This paper will review the effects of blast loading on a person protected by body armour; this will be broken down into: Theory of blast impact, Research into blast loading on different materials. Theory of blast impact. Blast waves are generated from the rapid expansion of gases produced during an explosion during which a shock wave, travelling faster than the speed of sound, propagates from the source of the explosion omni-directionally. One of the most important characteristics of a blast to consider is peak overpressure, which is, in effect, the strength of the blast. A further and equally important characteristic is the positive impulse duration, which determines the time that the force will be imparted on any object or structure. Both the peak overpressure and the positive impulse duration need to be known to effectively calculate the effects of a blast on an object. If you have two blasts of equal peak overpressure but one is acting for longer, the total force imparted on the object will be greater for the longer impulse and will affect the object more. Figure 1 shows an ideal blast wave representation. The pressure increases almost instantaneously to the peak overpressure and decays over time , a negative pressure phase then follows. Fig 1. Ideal blast wave resulting from an explosion in air. (Goel et al. 2012) The effect a blast wave has on a person is complicated due to how the blast wave interacts with the irregular shape of the human body. Blast wave diffraction around the human body results in a complex pressure load on the body all of which need to be understood to successfully gauge how a wave will affect a person. Figure 2 shows how a blast wave interacts with an irregularly shaped object, such as a human body. Fig 2. Illustrating the blast wave interaction with an irregularly shaped object. (Gibson 1989) Initially, a portion of the blast wave is reflected from the front of the body. The outer parts of the shock wave continue and diffracts around to the rear of the body where they are weakened. Rarefaction waves move across the front of the body (1), reducing the peak pressure of the reflected wave whilst vortices form at the rear of the body (2) and (3). The complicated gas flow means that the body is loaded for an extended time (Gibson 1989). The injuries caused by this peak initial pressure/positive impulse duration are known as primary blast injuries (PBI). The organs most susceptible to PBI are the gas-filled organs such as the ears, the lungs, and the gastrointestinal tract. The mechanism of injury on these organs is a form of barotrauma, which is an injury, caused by the pressure differential of the internal organs and the outer surface of the body at the moment the pressure wave impacts. Blast waves can be sub-divided into stress waves and shear waves. Shock waves are a special type of stress wave, which are longitudinal like sound waves but travel much faster, and cause primary blast injury (PBI) of the lung and small bowel. Shear waves are trans- verse waves, characterised by long duration, low velocity, and cause compression of visceral structures. In the abdomen, stress waves cause damage at the microscopic level, whereas the shear wave causes tearing of the tissues due to gross body wall and visceral motion. Laceration of solid abdominal viscera is related to very high blast loading (Housden 2012). Research into the effects of blast loading on a person protected by body armour. An interim report produced by the US Army Natick RDE Centre in 1989, titled Response of Clothing Materials to Air Shock Waves (Gibson 1989) provided remarkable insight into blast loading of high impact shock waves. The report focuses on testing the then, in-service body armour of the US Army (The Personnel Armor Systems, Ground Troops (PASGT)). The report covered four areas: Blast wave characteristics, Blast biology, Blast protection, Blast attenuation by porous and compressible materials. The main objective of the report was to ascertain how blast waves interacted with PASGT and it stated there was previous evidence that the materials contained within the body armour were causing a blast amplification effect. Initial thoughts were that this amplification might have been due to how the blast wave propagated through the multi-layered design of the armour. The report described the construction of the body armour (13 layers of Kevlar ® 29 cloth sandwiched between an inner and outer nylon shell fabric). The report explains that the armour was designed purely to provide ballistic protection and no thought had gone into providing protection against blast effects. The reports main focus was the lack of protection afforded to the wearer of the body armour from enhanced blast weapons such as Fuel-Air Explosives (FAE). A person can sustain injuries from a blast with overpressures that result in ranges as little as 10 20 psi whereas a typical FAE event can produce much more substantial psi, as high as 300. In this circumstance, the lack of protection armour would provide to the wearer was highly concerning. Prior to this report, a lot of basic work on the response of mammals to blast waves had been conducted by The Lovelace Foundation, The Research Institute of National Defence (Sweden), and the Walter Reed Army Institute of Research. This work identified how various characteristics of the blast can vary the effect of the blast on a body, such as the orientation of the body in relation to the blast wave. In one study conducted by Walter Reed Army Institute of Research, human volunteers were subjected to low level blast waves. The volunteers internal lung pressure was measured during the study whilst wearing several different types of protective clothing. The study showed that the volunteers wearing the PASGT body armour gave test measurements showing the greatest increase of internal lung pressure. This would suggest that the body armour would increase the risk of lung damage at higher blast overpressures. This study was extended to higher blast overpressures using sheep instead of human volunteers. Half of the sheep were fitted with PASGT body armour. During this testing, the level of damage to the sheeps lungs was measured by the percent increase of the lung weight. An assumption was made that this would directly relate to the blast damage. This extended study showed that the sheep wearing body armour displayed far greater blast damage to their lungs than the unprotected sheep. Analysis of the experimental data on how shock waves were transmitted through layers of material showed that there was a significant increase in the reflected pressure when compared to testing were no fabric was present. There was a trend of the pressure increasing in line with the number of layers of Kevlar or cotton present. This continued to a certain point. It was noted during these experiments that there was not significant difference between the increases of pressure when using layers of cotton compared to layers of Kevlar. This suggested that the type of material was not as significant as the number of layers and the density of the fabric. Analysis of the computer modelling showed an increase in peak internal lung pressure of around 50% between the unprotected chest model and the model wearing the body armour. A point to note, the experimental data compiled shows a measured increase of 20% in the human volunteers wearing the body armour compared to the unprotected volunteers. This disparity could be due to the difficulty in modelling the complex reaction of blast waves influencing a human body. The report concluded that soft body armour does not offer wearers protection from blast effects. On the contrary, the wearing of soft body armour may actually increase the blast effects on the personnel wearing the armour. The report does indicate that this counter -intuitive phenomena might be reduced with the introduction of hard armour plates to the body armour. A more recent confirmation of these findings were detailed in a journal article titled, Shock Enhancement Effect of Lightweight Composite Structures and Materials (Zhu et al. 2011). This review looks at the broader range of lightweight materials that are used to provide protection (namely ballistic). The author concludes that the research into the effects of lightweight materials is still very limited but the evidence still points to shock enhancement when using multi layered soft armour as PPE. A further study into shock attenuation was made following clinical studies into the increasing reporting of brain injury and not pulmonary injury following blast exposures. The article titled, Attenuation of Blast Pressure Behind Ballistic Protective Vests (Wood, 2012). This article concludes that following shock tube testing on two variants of body armour (NIJ Level 2 soft armour and NIJ Level 4 hard armour); results show a substantial increase in protection to the torso against blast injuries whilst wearing these armours. The behind armour overpressures were reduced by a factor of 14.2 and 56.8 for the NIJ 2 and NIJ 4 body armour, respectively. Conclusion This paper presents a review of the effects of blast loading on a person protected by body armour. A vast majority of the experimental data shows that the wearing of soft body armour enhances shock waves and the person is subjected to much higher peak overpressures. The combinations of differences in impedance between the atmosphere, the layers of fabric, the body itself, and the gas filed organs is likely to cause this phenomenon. Figure 3 shows the effect of interfaces in relation to shock waves. Using the shock impedance equation, you can show what is likely to be causing the enhancement of the blast. Stress is conserved across the interface between the air, the body armour, and the person: Z1 = 0 (Air) à ¢Ã‹â€ Ã‚ ´ à Ã†â€™2 = 2 x à Ã†â€™1 Assuming that the torso was of a similar impedance to the body armour, the next interface would be the gas-filled organs, which again would be of a lower impedance. This would result in the release of a tensile wave within the chest cavity, which could cause spalling of tissue with an increase of up to a factor of 2. Fig 3. Illustration of the effect of interfaces (Appleby-thomas 2017). Although there are many reviews on this subject, most of them seem to be focused on historical work. Teland (2012) noted that most of the blast injury prediction models are based on the Bowen curves, the Bass curves, and Axelsson BTD model. The report mentioned that there were many disadvantages and limitations to using these models and there is a need for further experimentation produce more reliable data. This may be due to the Computational models of how blast waves interact with the body armour and the wearer can be used but the theoretical models are limited. Using extrapolated data from experiments involving humans has limited uses because of the restriction on the size of blast you can subject a volunteer to without them becoming injured. The use of animals is of limited use due to the form fit of the body armour and the different anatomical makeup of the animals. Throughout the reports, reviews and articles studied during the writing of this paper, it is clear that a need for further study has been identified. Whether these recommendations have been carried out or not is not clear, there are no open source reports providing evidence; it may be that the information is classified.

Thomas Edison Essay -- essays research papers

Thomas Alva Edison is considered one of the greatest inventors in history. He was born in Milan, Ohio on February 11, 1847 and died in 1931. During his life he patented 1,093 inventions. Many of these inventions are in use today and changed the world forever. Some of his inventions include telegraphy, phonography, electric lighting and photography. His most famous inventions were the phonograph and the incandescent light bulb. Edison did some of his greatest work at Menlo Park. While experimenting on an underwater cable for the automatic telegraph, he found that the electrical resistance and conductivity of carbon varied accordingly to the pressure it was under. This was a major theoretical discovery, which enabled Edison to invent a "pressure relay" using carbon rather than magnets, which was the usual way to vary and balance electrical currents. In February of 1877 Edison began experiments designed to produce a pressure relay that would amplify and improve the audibility of the telephone, a device that Edison and others had studied but which Alexander Graham Bell was the first to patent, in 1876. By the end of 1877 Edison had developed the carbon-button transmitter that is still used today in telephone speakers and microphones. Many of Thomas Edison’s inventions including the carbon transmitter were in response to demands for new products and improvements. In 1877, he achieved his most unique discovery, the phonograph. During the summer of 1877 Edison was attempting to devise for the automatic telegraph a machine that would transcribe a signals as they were received into a form of the human voice so that they could then be delivered as telegraph messages. Some researchers had theorized that each sound, if it could be graphically recorded, would produce a distinct shape resembling short hand, or phonography, as it was known then. Edison hoped to make this concept real by employing a stylus-tipped carbon transmitter to make impressions on a strip of paraffined paper. To his amazement, the barley visible indentations generated a vague sound when the paper was pulled back beneath the stylus. In December 1877 Edison unveiled the tinfoil phonograph, which replaced the strip of paper wrapped in tinfoil. Many people would not believe what they were hearing including a leading French scientist who declared it to be a trick device of a ventri... ...ed whether something might be done, only how. Edison’s career, the fulfillment of the American dream of rags-to-riches through hard work and intelligence, made him a folk hero to his countrymen. In temperament he was an uninhibited egotist, at once a tyrant to his employees and their most entertaining companion, so that there was never a dull moment with him. He was charismatic and courted publicity, but he had difficulty socializing and neglected his family. His shafts at the expense of the "long-haired" fraternity of theorists sometimes led formally trained scientists to depreciate him as anti-intellectual; yet he employed as his aides, at various times a number of eminent mathematical physicists, such as Nicole Tesla and A.E. Kennelly. The contradictory nature of his forceful personality, as well as such eccentricities as his ability to catnap anywhere, contributed to his legendary status. By the time he was in his middle 30s Edison was said to be the best-known American in the world. When he died he was the venerated and mourned as the man who, more than any other, had laid the basis for the technological and social revolution of the modern electrical world.

Free Admissions Essay - Care for an Ethnically Diverse Population :: Medicine College Admissions Essays

Admissions Essay - Care for an Ethnically Diverse Population Crayfish tails in tarragon butter, galantine of rabbit with foie gras, oxtail in red wine, and apple tartelletes. The patient had this rich meal and complained of "liver upset" (crise de foie). Why a liver ache? I always associate indigestion with a stomach ache. In studying French culture in my Evolutionary Psychology class, I learned that when experiencing discomfort after a rich meal, the French assume their liver is the culprit. Understanding and dealing with the minor - sometimes major - cultural differences is a necessity in our shrinking world and diverse American society. Anthropology has prepared me to effectively communicate with an ethnically diverse population. My science classes, research, and clinical experience have prepared me to meet the demands of medical school. I first became aware of the valuable service that physicians provide when I observed my father, a surgeon, working in his office. I gained practical experience assisting him and his staff perform various procedures in his out-patient center. This exposure increased my admiration for the restorative, technological, and artistic aspects of surgery. I also saw that the application of medical knowledge was most effective when combined with compassion and empathy from the health care provider. While admiring my father's role as a head and neck surgeon helping people after severe accidents, I also found a way to help those suffering from debilitating ailments. Working as a certified physical trainer, I became aware of the powerful recuperative effects of exercise. I was able to apply this knowledge in the case of Sharon, a forty-three-year-old client suffering from lupus. she reported a 200% increase in her strength tests after I trained her. This meant she could once again perform simple tasks like carrying groceries into her house. Unfortunately, this glimpse of improvement was followed by a further deterioration in her condition. On one occasion, she broke down and cried about her declining health and growing fears. It was then that I learned no physical prowess or application of kinesiology would alleviate her pain. I helped reduce her anxiety with a comforting embrace. Compassion and understanding were the only remedies available, temporary though they were. To confirm that medicine is the best way for me to help others, I assisted a research team in the Emergency Room at University Medical Center (UMC).

Facebook Essay Writing Service Essay

Introduction Facebook is a social is a social network service which was founded by Mark Zuckerberg in February 2004. This is the most commonly used website with over 600million active users according to the report given in January 2011. This is considered to have created a very strong network of communication with its capability to connect people across the world. The services have both negative and positive effects to the individuals, families and societies since it is accessed by all the people irrespective of the age and experience. The study below concerns the major effects and consequences of this network service to the society at large. Effects or consequences of Facebook on the society Humans are social beings thus there is need for them top keep connected or have a good network to socialize with each other. According to the results of the study on Compete.com done in January 2009, Facebook was ranked to be the most used social network and it has more benefits than just communicating but also provision of essential information in communication. It is the best and the most powerful tool for collaboration and interaction between people or friends. Considering from the sociological perspective Facebook sites are considered to improve social capital which is particularly essential in striking up a conversation or enabling people to access information from the internet. A study carried out in Michigan State University found that the services are beneficial especially for eth individuals with low self esteem and less self satisfaction. From the psychological perspective, the site enables the individuals to meet and share with the others with common interests hence share the experiences and get motivated or gain knowledge to handle life issues (Goldman, 2008 p. 7). Facebook makes up a cheaper way of keeping up with friends by reinforcing the existing ones or expansion of the network by enabling the creation of new  ones. Each individual member has a profile page on which he or she invites all the people to be their friends. They post ideas on their walls to be shared amongst the friends and those of their friends and also have a chance of accessing what their friends have to share thus more and diverse information and knowledge is shared. It also serves to strengthen the bonds especially between the individuals who do not have enough physical contact or have not enough time for direct interaction. This is possible by providing individual information as well as views and opinions thus the others may be able to learn more concerning the individuals. There is a lot to be done thus people do not have enough time to visit or interact with their friends, Facebook offers the opportunity for the individuals to interact and share views and opinions even as they carry on other duties. It is a good chance for the individuals to gather information concerning people of interest like professionals thus they may be able to approach them on official duties by knowing their personalities. People acquire more and diverse information from all corners of the world, for example the cultures of the other communities and how various individuals across the world handle life challenges. It is a good and effective medium of communication since so long as the facilities are available the account holders access the sites on daily basis either on computers or through the mobile phone hand sets (Matthew, 2008 p. 345-365). Other than the benefits these social services also have disadvantages on the society. Excess usage of these social sites is resulting to the increase in the societal crime rates especially those relating to immorality or sexual abuse. There is no age description of the individuals who are qualified to hold accounts on the Facebook thus the young children, the teenagers and the adults all share the information that is posted on the profiles. The young people access and put in practice ideas which are far much below their standards. Some of these may be pornographic materials which may abuse the young children. Excessively exposing of the information concerning people for example, their occupation is having effects on the societal crime rates for instance the robbery and carjacking because the criminals will be able to identify the individuals of their focus and monitor their movement  depending on the information that they provide (Martà ­nez, 2009 p. 73-82). Although these networks are considered as an effective links for the distance relationships by connecting the individuals, it also has negative effects on the relationships. This is resulting to wrong decisions because the individuals may be influenced to be engaged in bad relationships. Most of the people who use these websites do not express their original characters but mostly try to show the best. Some of these relationships may not last because the parties are forced to separate when they learn the true characters of the others. The individuals also blame each other for being unfaithful through by accessing the information that they share with the others. Most of the people especially the young people are not able to balance the time that they spend on these sites and on the other activities. Many of the employers are complaining of their employees not producing the best or as expected as they spend most of the time chatting or sharing ideas with their online friends. This is found to be one of the factors causing the financial instability in the society as many of the people do not concentrate on the economic activities. The learning institutions are also not left out especially the colleges and other higher learning institutions. The performance of these institutions are declining since the students spend most of their time on these social networking thus they have no time for their assignments and studies. These students are forced to either dump the assignment or examination tests if they are not well prepared or have not revised. After they are through with the training they are not able to maintain a good relationship with their employers since they do not concentrate in their workplaces or may not have acquired enough skills to perform their duties as expected (Sonvilla-Weiss, 2010 p. 102-112). The more time the individuals spend on the social networking sites, the huge the content of their privacy they expose to the public as they post their ideas, feelings and interests online. The society seems to be becoming more open without any privacy thus some people are becoming unappreciated in the societies when the personalities discovered of them are unexpected. This is  also affecting the social relationships between the casual friends, children and the adults or parents because some of the information exposed shows the individuals to be lacking good moral behavior especially if the information they share is more intimate thus their parents or friends are likely to mistake them. This site is seen as a face value of the society we live in although a times it communicate false information (Gutwirth, 2010 p. 127). The cultures of the societies are highly changing due to the influence of the Facebook. This is because people are forced to change and adapt the styles of living acquired from the information that they share with the rest of the people from across the world. Some of these cultures for instance the language change is not acceptable in most of the communities. For example, the language used by the children to address the adults in certain communities may not be accepted in others and are likely to cause disagreements. This is reflected by the gap between the older and the young generations in the societies since the older people consider the young ones to be misled by the current events in the society thus are reluctant to interact with them (Matthew, 2008 p. 276-281). The social networking is considered to be having effects to all the life factors including political, social and economic. By interacting with the others the local leaders have an opportunity to share and copy the leadership styles which may or may not be accepted in the societies although a times they have positive impacts. It also have both negative and positive impacts in the economic sector since people wastes a lot of time on them than they do on the economic boosting activities. They may also provide ideas on new activities of economic development through sharing with the others. Conclusion Facebook is a social networking site which is the most popular and widely used to connect across the world. It has both negative and positive impacts to the society through influencing all the life aspects like political, social and economic. The leaders have an opportunity to share with the other  leaders across the world thus they improve their leadership skills. Although some of the people waste a lot of time on the sites other than carrying out the economic activities, sometime they benefit by acquiring new ideas on economic activities.

Domestic Violence Is Mainly Caused by Poverty

Domestic violence is widely interpreted as a form of disparaging actions carried out by either one or both parties in a relationship such as marriage, siblings, friends or any people who essentially live together. Some forms of domestic violence include domestic abuse, spousal abuse, child abuse and intimate partner violence (IPV). They who tend to be hostile by being physically aggressive, sexually or mentally abusive, intimidating or neglecting, etc. towards the other party are the one carrying out domestic violence (Wikipedia).Although this matter may not have enacted a crime but this matter is on its increase and has given nuisance to many that are involved. Domestic violence is found all throughout the world no matter what the country, race or class. I disagree with the fact that domestic violence is mainly caused by poverty because there have been cases of domestic violence found in the upper class as well. Although domestic violence does occur in poor households; other reasons that domestic violence occurs include drug and alcohol abuse, a household filled with self-esteem issues and the absence of God.Alcohol and drug abuse is another reason why domestic violence exists in our world (All About Life Challenges n. d. ). The most prominent form of domestic violence is male-to-female violence. This can be either husband to wife, husband to children or husband to other members of the family living under the same roof. Alcohol and drug abuse definitely adds another dimension to this violence. Heavy alcohol use makes users rowdy and willing to wreak havoc even without a valid reason.Alcohol has always been a root cause of many problems mainly because of the fact that it leads to out-of-control behaviour. A person is very different from himself when he is under the heavy influence of alcohol. Fathers who drink liquor every night are much more prone to domestic violence than a father who is not an alcoholic. Drugs such as crack, cocaine and methamphetamine make users aggressive and also cause dependence. People high on crack think that they can do anything and heavy users start experiencing paranoia (Drug Intelligence Centre n. . ). This paranoia causes the user to make a problem out of nothing and the aggressiveness of the drug initiates the violence. Drugs and alcohol do contribute heavily to domestic violence but another very big reason is self-esteem issues. A lot of domestic violence issues always have something to do with self-esteem issues. A child growing up in an environment where he is regularly beaten and put down will have psychological problems when he/she grows up. The hidden burning anger of that child will stay inside him until he grows up.When that child, who is now a man, has a family of his own it is very likely that he will take out all his childhood frustrations on his family. This might be caused by stress or even the willingness to show power and control (All About Life Challenges n. d. ). Sometimes a family will exp erience domestic violence because the violator feels the need to show that he is the boss of the house. The father who has been battling self-esteem issues all his life regularly violates his family to convince himself that he is the boss of the house.This might be because that person has never been in a position of power all his life and has been regularly put down by society. This person will most likely have difficulty coping with stress, be unwilling to take responsibility of his own actions and experience extreme jealousy and possessiveness among other alcohol/tobacco/drug problems (Domestic Violence). People who believe in God tend to stay away from evil thoughts and doings. Domestic violence is mostly taking place in homes that are without God’s guidance. Most religions around the globe are against any type of violence.The Bible, for example, encourages its followers to be at peace with all mankind (All About Life Challenges n. d. ). Homes where domestic violence occur s have very little or no faith in God. Islam is known as one of the most peaceful religions in the world. The Quran, which is the holy book of Muslims, preaches that conflicts should be solved using communication rather than violent actions. Hinduism, Judaism, Buddhism and many more religions follow the same code of ethics. When child abuse occurs there is obviously an absence of religion in the home.For the counter argument, domestic violence does occur in homes rued with financial crises. According to a recent survey, domestic violence has been more prevalent in low-income families compared to middle and upper class families. Experts state that there tend to be more abuse cases in poor families that are reported to ER staff, police and social services. Violators from the lower class are more likely to be apprehended by the authorities because they do not have the power or influence which is prevalent in the upper class families (Domestic Violence Tips).To conclude this essay I wou ld like to state that domestic violence does occur in areas affected by poverty, but that is not the only factor which contributes to this violence. Domestic violence is prevalent in families that are ridden with alcohol and drug abuse problems. As stated before an alcoholic father will beat his children for matters which do not require punishment. A family which has a history of self-esteem issues is also extremely prone to domestic abuse because they tend to feel inferior among the other members of the family whether in economic, education or status prospect.Children who grew up in a family or community with history of abuse may think that violence is a reasonable way to solve conflicts between people. The other reason why domestic violence is on a rise is because of the absence of God in certain households. A household which follows the religion of choice will abstain from violent behaviour of any kind. Domestic violence is a crime which is on the rise especially in developing co untries. One way to reduce these crimes is to educate the youth. Hopefully in the next few years domestic violence will be a thing of the past.
