Energy Drinks Rationale Essay

Rationale Energy drinks were maufactured for the purpose of providing mental and physical stimulation for a short period of time. They are specially formulated for people who needs extra energy and are looking for a temporary mental and physical booster in order to get through day to day’s activity. Energy drinks sprung in the global market wayback 1997 with Red Bull being the very first product that hit the market. Energy drinks contain different ingredients such as caffeine, sugars, taurine, ginseng, guarana extract, and other ingredients such as vitamins and amino acids. Indeed, energy drinks are useful especially for those people who are exposed to heavy work and thinking and need an extra energy to do so. But along with the benefits that one may get in ingesting energy drinks comes the negative effects it may give in one’s body. The energy drink market is a fast-growing market, as it remains as the most dynamic segment on the soft drinks market, with strong growth in most market, according to Zenith International. It is most popular to athletes, people in professions, and students. This study is conducted to study the good and bad effects energy drinks may bring to those who ingest it, focusing specially on college students who are most likely exposed to different kind of stress and energy-draining activities such as studying. Since the focus of the study is towards the college students, the research’s aim is to explain the effects of energy drinks to the college student’s health and school performance, to weigh the good effects and the downside of ingesting it, to suggest some ideas for the betterment of the situation or for the elimination of problems encountered, and to find some alternatives for those situations which are found and proven ineffective. The discovery of energy drinks has been phenomenal. Its global consumption over the last five years has grown by about 10% anually, and now it is sold in over 160 countries worldwide, with 44% of it purchased in convenience strores and 56% purchased in bars and other places. Most of its consumers ae students. Indeed, energy drinks are very helpful to those students who need to stay awake late at night to study for a test, who are making reports, projects, assignments and other schoolworks. Energy drinks contribute in staying awake and focus. But mcuh to our knowledge, energy drinks has limitations. They  may provide extra energy, but it is temporary. They just stimulate the body and brain over a short period of time. They also do not provide an effective way of rehydrating our body and stay in our stomach longer than water because of high sugar concentration. Energy drinks, when taken up without precaution, may cause a serious problem to one’s body. Energy drinks contain caffeine, a primary content of coffee. The caffeine content of an enery drink is about 80 mg per 250 ml, equivalent to one cup of coffee. But there are energy drinks sold in larger containers, which means more caffeine content. Caffeine overdose may cause side effects such as nervousness, insomnia, palpitation, dizziness, nausea, and headache. There were reported cases of hospitalizations due to these symptoms, and even death. According to Dr. Matteo Cameli. from University of Siena, despite of its dominant bad effects to the body, they found a health benefit that it may bring in one of their studies. He explained that energy drinks enhance the contractions of both the left and right ventricle of the heart. This may be because of the effect of taurine which stimulates the release of calcium from the sarcoplasmic reticulum. But despite this effect, he still added that energy drinks raise the risk if cardiometabolic disease. Most cases of energy drink symptoms and toxicity are mainly caused by the effects of high-caffeine intake of the body. Most of the labels of energy drinks containers don’t really specify the contents, warnings and dosage that’s why harmful events occurs. For example, energy drinks contain guarana, which contains caffeine, but the caffeine content is not specified in the label, therefore the caffeine content of that energy drink might be higher than what is reflected. Also, most of the college students are not really typical on what is written on the labels. They must be aware on what is written on labels such as recommended use, recommended dosage, intended population, precaution, and list of ingredients. They must also be aware that the maximum recommended dosage in general is one or two cans a day. It is necessary to read the labels before purchasing a product. There are alternative ways to boost energy without taking in energy drinks, such as making one’s own energy drinks by means of natural ingredients such as fruits. In that way, they can make sure that what they are drinking are safer compared to over-the-counter energy drinks.

Blood pressure Essay Example for Free (#2)

Blood pressure Essay Blood pressure (BP), sometimes referred to as arterial blood pressure, is the pressureexerted by circulating blood upon the walls of blood vessels, and is one of the principal vital signs. When used without further specification, â€Å"blood pressure† usually refers to thearterial pressure of the systemic circulation. During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure.[1] The blood pressure in the circulation is principally due to the pumping action of the heart.[2] Differences in mean blood pressure are responsible for blood flow from one location to another in the circulation. The rate of mean blood flow depends on the resistance to flow presented by the blood vessels. Mean blood pressure decreases as the circulating blood moves away from the heart through arteries and capillaries due to viscous losses of energy. Mean blood pressure drops over the whole circulation, although most of the fall occurs along the small arteries and arterioles.[3] Gravity affects blood pressure via hydrostatic forces (e.g., during standing) and valves in veins, breathing, and pumping from contraction of skeletal muscles also influence blood pressure in veins.[2] The measurement blood pressure without further specification usually refers to the systemic arterial pressure measured at a person’s upper arm and is a measure of the pressure in the brachial artery, major artery in the upper arm. A person’s blood pressure is usually expressed in terms of the systolic pressure over diastolic pressure and is measured in millimetres of mercury (mmHg), for example 120/80. The table on the right shows the classification of blood pressure adopted by the American Heart Association for adults who are 18 years and older.[4] It assumes the values are a result of averaging blood pressure readings measured at two or more visits to the doctor.[6][7] In the UK, blood pressures are usually categorised into three groups: low (90/60 or lower), high (140/90 or higher), and normal (values above 90/60 and below 130/80).[8][9] While average values for arterial pressure could be computed for any given population, there is often a large variation from person to person; arterial pressure also varies in individuals from moment to moment. Additionally, the average of any given population may have a questionable correlation with its general health; thus the relevance of such average values is equally questionable. However, in a study of 100 human subjects with no known history of hypertension, an average blood pressure of 112/64 mmHg was found,[10] which are currently classified as desirable or â€Å"normal† values. Normal values fluctuate through the 24-hour cycle, with highest readings in the afternoons and lowest readings at night.[11][12] Various factors, such as age and sex influence average values, influence a person’s average blood pressure and variations. In children, the normal ranges are lower than for adults and depend on height.[13] As adults age, systolic pressure tends to rise and diastolic tends to fall.[14] In the elderly, blood pressure tends to be above the normal adult range,[15] largely because of reduced flexibility of the arteries. Also, an individual’s blood pressure varies with exercise, emotional reactions, sleep, digestion and time of day. Differences between left and right arm blood pressure measurements tend to be random and average to nearly zero if enough measurements are taken. However, in a small percentage of cases there is a consistent difference greater than 10 mmHg which may need further investigation, e.g. for obstructive arterial disease.[16][17] The risk of cardiovascular disease increases progressively above 115/75 mmHg.[18] In the past, hypertension was only diagnosed if secondary signs of high arterial pressure were present, along with a prolonged high systolic pressure reading over several visits. Regarding hypotension, in practice blood pressure is considered too low only if noticeable symptoms are present.[5] Clinical trials demonstrate that people who maintain arterial pressures at the low end of these pressure ranges have much better long term cardiovascular health. The principal medical debate concerns the aggressiveness and relative value of methods used to lower pressures into this range for those who do not maintain such pressure on their own. Elevations, more commonly seen in older people, though often considered normal, are associated with increased morbidity and mortality. There are many physical factors that influence arterial pressure. Each of these may in turn be influenced by physiological factors, such as diet, exercise, disease, drugs or alcohol, stress, obesity, and so-forth.[20] †¢ Volume of fluid or blood volume, the amount of blood that is present in the body. The more blood present in the body, the higher the rate of blood return to the heart and the resulting cardiac output. There is some relationship between dietary salt intake and increased blood volume, potentially resulting in higher arterial pressure, though this varies with the individual and is highly dependent on autonomic nervous system response and the renin-angiotensin system.[21][22][23] †¢ Resistance. In the circulatory system, this is the resistance of the blood vessels. The higher the resistance, the higher the arterial pressure upstream from the resistance to blood flow. Resistance is related to vessel radius (the larger the radius, the lower the resistance), vessel length (the longer the vessel, the higher the resistance), blood viscosity, as well as the smoothness of the blood vessel walls. Smoothness is reduced by the build up of fatty deposits on the arterial walls. Substances called vasoconstrictors can reduce the size of blood vessels, thereby increasing blood pressure. Vasodilators (such as nitroglycerin) increase the size of blood vessels, thereby decreasing arterial pressure. Resistance, and its relation to volumetric flow rate (Q) and pressure difference between the two ends of a vessel are described by Poiseuille’s Law. †¢ Viscosity, or thickness of the fluid. If the blood gets thicker, the result is an increase in arterial pressure. Certain medical conditionscan change the viscosity of the blood. For instance, anemia (low red blood cell concentration), reduces viscosity, whereas increased red blood cell concentration increases viscosity. It had been thought that aspirin and related â€Å"blood thinner† drugs decreased the viscosity of blood, but instead studies found[24] that they act by reducing the tendency of the blood to clot. In practice, each individual’s autonomic nervous system responds to and regulates all these interacting factors so that, although the above issues are important, the actual arterial pressure response of a given individual varies widely because of both split-second and slow-moving responses of the nervous system and end organs. These responses are very effective in changing the variables and resulting blood pressure from moment to moment. Moreover, blood pressure is the result of cardiac output increased by peripheral resistance: blood pressure = cardiac output Xperipheral resistance. As a result, an abnormal change in blood pressure is often an indication of a problem affecting the heart’s output, the blood vessels’ resistance, or both. Thus, knowing the patient’s blood pressure is critical to assess any pathology related to output and resistance. The mean arterial pressure (MAP) is the average over a cardiac cycle and is determined by the cardiac output (CO), systemic vascular resistance (SVR), and central venous pressure (CVP),[25] Curve of the arterial pressure during one cardiac cycle The up and down fluctuation of the arterial pressure results from the pulsatile nature of thecardiac output, i.e. the heartbeat. The pulse pressure is determined by the interaction of thestroke volume of the heart, compliance (ability to expand) of the aorta, and the resistance to flow in the arterial tree. By expanding under pressure, the aorta absorbs some of the force of the blood surge from the heart during a heartbeat. In this way, the pulse pressure is reduced from what it would be if the aorta wasn’t compliant.[26] The loss of arterial compliance that occurs with aging explains the elevated pulse pressures found in elderly patients. The pulse pressure can be simply calculated from the difference of the measured systolic and diastolic pressures,[26] The arm–leg (blood pressure) gradient is the difference between the blood pressure measured in the arms and that measured in the legs. It is normally less than 10 mmHg,[27] but may be increased in e.g. coarctation of the aorta.[27] The larger arteries, including all large enough to see without magnification, are conduits with low vascular resistance (assuming no advanced atherosclerotic changes) with high flow rates that generate only small drops in pressure. The smaller arteries and arterioles have higher resistance, and confer the main drop in blood pressure along the circulatory system. Modern physiology developed the concept of the vascular pressure wave (VPW). This wave is created by the heart during the systoleand originates in the ascending aorta. Much faster than the stream of blood itself, it is then transported through the vessel walls to the peripheral arteries. There the pressure wave can be palpated as the peripheral pulse. As the wave is reflected at the peripheral veins, it runs back in a centripetal fashion. When the reflected wave meets the next outbound pressure wave, the pressure inside the vessel rises higher than the pressure in the aorta. This concept explains why the arterial pressure inside the peripheral arteries of the legs and arms is higher than the arterial pressure in the aorta,[28][29][30] and in turn for the higher pressures seen at the ankle compared to the arm with normal ankle brachial pressure index values. The endogenous regulation of arterial pressure is not completely understood, but the following mechanisms of regulating arterial pressure have been well-characterized: †¢ Baroreceptor reflex: Baroreceptors in the high pressure receptor zones detect changes in arterial pressure. These baroreceptors send signals ultimately to the medulla of the brain stem, specifically to the Rostral ventrolateral medulla (RVLM). The medulla, by way of the autonomic nervous system, adjusts the mean arterial pressure by altering both the force and speed of the heart’s contractions, as well as the total peripheral resistance. The most important arterial baroreceptors are located in the left and rightcarotid sinuses and in the aortic arch.[31] †¢ Renin-angiotensin system (RAS): This system is generally known for its long-term adjustment of arterial pressure. This system allows the kidney to compensate for loss in blood volume or drops in arterial pressure by activating an endogenous vasoconstrictorknown as angiotensin II. †¢ Aldosterone release: This steroid hormone is released from the adrenal cortex in response to angiotensin II or high serum potassiumlevels. Aldosterone stimulates sodium retention and potassium excretion by the kidneys. Since sodium is the main ion that determines the amount of fluid in the blood vessels by osmosis, aldosterone will increase fluid retention, and indirectly, arterial pressure. †¢ Baroreceptors in low pressure receptor zones (mainly in the venae cavae and the pulmonary veins, and in the atria) result in feedback by regulating the secretion of antidiuretic hormone (ADH/Vasopressin), renin and aldosterone. The resultant increase inblood volume results an increased cardiac output by the Frank–Starling law of the heart, in turn increasing arterial blood pressure. These different mechanisms are not necessarily independent of each other, as indicated by the link between the RAS and aldosterone release. Currently, the RAS is targeted pharmacologically by ACE inhibitors and angiotensin II receptor antagonists. The aldosterone system is directly targeted by spironolactone, an aldosterone antagonist. The fluid retention may be targeted by diuretics; the antihypertensive effect of diuretics is due to its effect on blood volume. Generally, the baroreceptor reflex is not targeted in hypertensionbecause if blocked, individuals may suffer from orthostatic hypotension and fainting. A medical student checking blood pressure using a sphygmomanometer and stethoscope. Arterial pressure is most commonly measured via a sphygmomanometer, which historically used the height of a column of mercury to reflect the circulating pressure.[32] Blood pressure values are generally reported in millimetres of mercury (mmHg), though aneroid and electronic devices do not use mercury. For each heartbeat, blood pressure varies between systolic and diastolic pressures. Systolic pressure is peak pressure in the arteries, which occurs near the end of the cardiac cyclewhen the ventricles are contracting. Diastolic pressure is minimum pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are filled with blood. An example of normal measured values for a resting, healthy adult human is 120 mmHgsystolic and 80 mmHg diastolic (written as 120/80 mmHg, and spoken [in the US and UK] as â€Å"one-twenty over eighty†). Systolic and diastolic arterial blood pressures are not static but undergo natural variations from one heartbeat to another and throughout the day (in a circadian rhythm). They also change in response to stress, nutritional factors, drugs, disease, exercise, and momentarily from standing up. Sometimes the variations are large. Hypertension refers to arterial pressure being abnormally high, as opposed to hypotension, when it is abnormally low. Along with body temperature, respiratory rate, and pulse rate, blood pressure is one of the four main vital signs routinely monitored by medical professionals and healthcare providers.[33] Measuring pressure invasively, by penetrating the arterial wall to take the measurement, is much less common and usually restricted to a hospital setting. The noninvasive auscultatory and oscillometric measurements are simpler and quicker than invasive measurements, require less expertise, have virtually no complications, are less unpleasant and less painful for the patient. However, noninvasive methods may yield somewhat lower accuracy and small systematic differences in numerical results. Noninvasive measurement methods are more commonly used for routine examinations and monitoring. A minimum systolic value can be roughly estimated by palpation, most often used in emergency situations, but should be used with caution.[34] It has been estimated that, using 50% percentiles, carotid, femoral and radial pulses are present in patients with a systolic blood pressure > 70 mmHg, carotid and femoral pulses alone in patients with systolic blood pressure of > 50 mmHg, and only a carotid pulse in patients with a systolic blood pressure of > 40 mmHg.[34] A more accurate value of systolic blood pressure can be obtained with a sphygmomanometer and palpating the radial pulse.[35] The diastolic blood pressure cannot be estimated by this method.[36] The American Heart Association recommends that palpation be used to get an estimate before using the auscultatory method. Auscultatory method aneroid sphygmomanometer with stethoscope Mercury manometer The auscultatory method (from the Latin word for â€Å"listening†) uses a stethoscope and asphygmomanometer. This comprises an inflatable (Riva-Rocci) cuff placed around the upperarm at roughly the same vertical height as the heart, attached to a mercury or aneroidmanometer. The mercury manometer, considered the gold standard, measures the height of a column of mercury, giving an absolute result without need for calibration and, consequently, not subject to the errors and drift of calibration which affect other methods. The use of mercury manometers is often required in clinical trials and for the clinical measurement of hypertension in high-risk patients, such as pregnant women. A cuff of appropriate size is fitted smoothly and snugly, then inflated manually by repeatedly squeezing a rubber bulb until the artery is completely occluded. Listening with the stethoscope to the brachial artery at the elbow, the examiner slowly releases the pressure in the cuff. When blood just starts to flow in the artery, the turbulent flow creates a â€Å"whooshing† or pounding (first Korotkoff sound). The pressure at which this sound is first heard is the systolic blood pressure. The cuff pressure is further released until no sound can be heard (fifth Korotkoff sound), at the diastolic arterial pressure. The auscultatory method is the predominant method of clinical measurement.[37] The oscillometric method was first demonstrated in 1876 and involves the observation of oscillations in the sphygmomanometer cuff pressure[38] which are caused by the oscillations of blood flow, i.e., the pulse.[39] The electronic version of this method is sometimes used in long-term measurements and general practice. It uses a sphygmomanometer cuff, like the auscultatory method, but with an electronic pressure sensor (transducer) to observe cuff pressure oscillations, electronics to automatically interpret them, and automatic inflation and deflation of the cuff. The pressure sensor should be calibrated periodically to maintain accuracy. Oscillometric measurement requires less skill than the auscultatory technique and may be suitable for use by untrained staff and for automated patient home monitoring. The cuff is inflated to a pressure initially in excess of the systolic arterial pressure and then reduced to below diastolic pressure over a period of about 30 seconds. When blood flow is nil (cuff pressure exceeding systolic pressure) or unimpeded (cuff pressure below diastolic pressure), cuff pressure will be essentially constant. It is essential that the cuff size is correct: undersized cuffs may yield too high a pressure; oversized cuffs yield too low a pressure. When blood flow is present, but restricted, the cuff pressure, which is monitored by the pressure sensor, will vary periodically in synchrony with the cyclic expansion and contraction of the brachial artery, i.e., it will oscillate. The values of systolic and diastolic pressure are computed, not actually measured from the raw data, using an algorithm; the computed results are displayed. Oscillometric monitors may produce inaccurate readings in patients with heart and circulation problems, which include arterial sclerosis, arrhythmia, preeclampsia, pulsus alternans, and pulsus paradoxus. In practice the different methods do not give identical results; an algorithm and experimentally obtained coefficients are used to adjust the oscillometric results to give readings which match the auscultatory results as well as possible. Some equipment uses computer-aided analysis of the instantaneous arterial pressure waveform to determine the systolic, mean, and diastolic points. Since many oscillometric devices have not been validated, caution must be given as most are not suitable in clinical and acute care settings. The term NIBP, for non-invasive blood pressure, is often used to describe oscillometric monitoring equipment. Continuous noninvasive techniques (CNAP) Continuous Noninvasive Arterial Pressure (CNAP) is the method of measuring arterial blood pressure in real-time without any interruptions and without cannulating the human body. CNAP combines the advantages of the following two clinical â€Å"gold standards†: it measures blood pressure continuously in real-time like the invasive arterial catheter system and it is noninvasive like the standard upper arm sphygmomanometer. Latest developments in this field show promising results in terms of accuracy, ease of use and clinical acceptance. Non-occlusive techniques: the Pulse Wave Velocity (PWV) principle Since the 90s a novel family of techniques based on the so-called Pulse wave velocity (PWV) principle have been developed. These techniques rely on the fact that the velocity at which an arterial pressure pulse travels along the arterial tree depends, among others, on the underlying blood pressure.[40] Accordingly, after a calibration maneuver, these techniques provide indirect estimates of blood pressure by translating PWV values into blood pressure values.[41] The main advantage of these techniques is that it is possible to measure PWV values of a subject continuously (beat-by-beat), without medical supervision, and without the need of inflating brachial cuffs. PWV-based techniques are still in the research domain and are not adapted to clinical settings. For some patients, blood pressure measurements taken in a doctor’s office may not correctly characterize their typical blood pressure.[42] In up to 25% of patients, the office measurement is higher than their typical blood pressure. This type of error is calledwhite-coat hypertension (WCH) and can result from anxiety related to an examination by a health care professional.[43] The misdiagnosis of hypertension for these patients can result in needless and possibly harmful medication. WCH can be reduced (but not eliminated) with automated blood pressure measurements over 15 to 20 minutes in a quiet part of the office or clinic.[44] Debate continues regarding the significance of this effect.[citation needed] Some reactive patients will react to many other stimuli throughout their daily lives and require treatment. In some cases a lower blood pressure reading occurs at the doctor’s office.[45] Ambulatory blood pressure devices that take readings every half hour throughout the day and night have been used for identifying and mitigating measurement problems like white-coat hypertension. Except for sleep, home monitoring could be used for these purposes instead of ambulatory blood pressure monitoring.[46] Home monitoring may be used to improve hypertension management and to monitor the effects of lifestyle changes and medication related to blood pressure.[6] Compared to ambulatory blood pressure measurements, home monitoring has been found to be an effective and lower cost alternative,[46][47][48] but ambulatory monitoring is more accurate than both clinic and home monitoring in diagnosing hypertension. Ambulatory monitoring is recommended for most patients before the start of antihypertensive drugs.[49] Aside from the white-coat effect, blood pressure readings outside of a clinical setting are usually slightly lower in the majority of people. The studies that looked into the risks from hypertension and the benefits of lowering blood pressure in affected patients were based on readings in a clinical environment. When measuring blood pressure, an accurate reading requires that one not drink coffee, smoke cigarettes, or engage in strenuous exercise for 30 minutes before taking the reading. A full bladder may have a small effect on blood pressure readings; if the urge to urinate arises, one should do so before the reading. For 5 minutes before the reading, one should sit upright in a chair with one’s feet flat on the floor and with limbs uncrossed. The blood pressure cuff should always be against bare skin, as readings taken over a shirt sleeve are less accurate. During the reading, the arm that is used should be relaxed and kept at heart level, for example by resting it on a table.[50] Since blood pressure varies throughout the day, measurements intended to monitor changes over longer time frames should be taken at the same time of day to ensure that the readings are comparable. Suitable times are: †¢ immediately after awakening (before washing/dressing and taking breakfast/drink), while the body is still resting, †¢ immediately after finishing work. Automatic self-contained blood pressure monitors are available at reasonable prices, some of which are capable of Korotkoff’s measurement in addition to oscillometric methods, enabling irregular heartbeat patients to accurately measure their blood pressure at home. Arterial blood pressure (BP) is most accurately measured invasively through an arterial line. Invasive arterial pressure measurement with intravascular cannulae involves direct measurement of arterial pressure by placing a cannula needle in an artery (usually radial, femoral,dorsalis pedis or brachial). The cannula must be connected to a sterile, fluid-filled system, which is connected to an electronic pressure transducer. The advantage of this system is that pressure is constantly monitored beat-by-beat, and a waveform (a graph of pressure against time) can be displayed. This invasive technique is regularly employed in human and veterinary intensive care medicine, anesthesiology, and for research purposes. Cannulation for invasive vascular pressure monitoring is infrequently associated with complications such as thrombosis, infection, andbleeding. Patients with invasive arterial monitoring require very close supervision, as there is a danger of severe bleeding if the line becomes disconnected. It is generally reserved for patients where rapid variations in arterial pressure are anticipated. Invasive vascular pressure monitors are pressure monitoring systems designed to acquire pressure information for display and processing. There are a variety of invasive vascular pressure monitors for trauma, critical care, and operating room applications. These include single pressure, dual pressure, and multi-parameter (i.e. pressure / temperature). The monitors can be used for measurement and follow-up of arterial, central venous, pulmonary arterial, left atrial, right atrial, femoral arterial, umbilical venous, umbilical arterial, and intracranial pressures. Further information: Fetal circulation#Blood pressure In pregnancy, it is the fetal heart and not the mother’s heart that builds up the fetal blood pressure to drive its blood through the fetal circulation. The blood pressure in the fetal aorta is approximately 30 mmHg at 20 weeks of gestation, and increases to approximately 45 mmHg at 40 weeks of gestation.[51] The average blood pressure for full-term infants: Systolic 65–95 mm Hg Diastolic 30–60 mm Hg[52] Blood pressure is the measurement of force that is applied to the walls of the blood vessels as the heart pumps blood throughout the body.[53] The human circulatory system is 400,000 miles long, and the magnitude of blood pressure is not uniform in all the blood vessels in the human body. The blood pressure is determined by the diameter, flexibility and the amount of blood being pumped through the blood vessel.[53] Blood pressure is also affected by other factors including exercise, stress level, diet and sleep. The average normal blood pressure in the brachial artery, which is the next direct artery from the aorta after the subclavian artery, is 120mmHg/80mmHg. Blood pressure readings are measured in millimeters of mercury (mmHg) using sphygmomanometer. Two pressures are measured and recorded namely as systolic and diastolic pressures. Systolic pressure reading is the first reading, which represents the maximum exerted pressure on the vessels when the heart contracts, while the diastolic pressure, the second reading, represents the minimum pressure in the vessels when the heart relaxes.[54] Other major arteries have similar levels of blood pressure recordings indicating very low disparities among major arteries. The innominate artery, the average reading is 110/70mmHg, the right subclavian artery averages 120/80 and the abdominal aorta is 110/70mmHg.[55] The relatively uniform pressure in the arteries indicate that these blood vessels act as a pressure reservoir for fluids that are transported within them. Pressure drops gradually as blood flows from the major arteries, through the arterioles, the capillaries until blood is pushed up back into the heart via the venules, the veins through the vena cava with the help of the muscles. At any given pressure drop, the flow rate is determined by the resistance to the blood flow. In the arteries, with the absence of diseases, there is very little or no resistance to blood. The vessel diameter is the most principal determinant to control resistance. Compared to other smaller vessels in the body, the artery has a much bigger diameter (4mm), therefore the resistance is low.[55] In addition, flow rate (Q) is also the product of the cross-sectional area of the vessel and the average velocity (Q = AV). Flow rate is directly proportional to the pressure drop in a tube or in this case a vessel. ∆P ÃŽ ± Q. The relationship is further described by Poisseulle’s equation ∆P = 8 µlQ/Ï€r4.[56] As evident in the Poisseulle’s equation, although flow rate is proportional to the pressure drop, there are other factors of blood vessels that contribute towards the difference in pressure drop in bifurcations of blood vessels. These include viscosity, length of the vessel, and radius of the vessel. Factors that determine the flow’s resistance as described by Poiseuille’s relationship: †¢ ∆P: pressure drop/gradient †¢  µ: viscosity †¢ l: length of tube. In the case of vessels with infinitely long lengths, l is replaced with diameter of the vessel. †¢ Q: flow rate of the blood in the vessel †¢ r: radius of the vessel Assuming steady, laminar flow in the vessel, the blood vessels behavior is similar to that of a pipe. For instance if p1 and p2 are pressures are at the ends of the tube, the pressure drop/gradient is:[57] In the arterioles blood pressure is lower than in the major arteries. This is due to bifurcations, which cause a drop in pressure. The more bifurcations, the higher the total cross-sectional area, therefore the pressure across the surface drops. This is why the arterioles have the highest pressure-drop. The pressure drop of the arterioles is the product of flow rate and resistance: ∆P=Q xresistance. The high resistance observed in the arterioles, which factor largely in the ∆P is a result of a smaller radius of about 30  µm.[58] The smaller the radius of a tube, the larger the resistance to fluid flow. Immediately following the arterioles are the capillaries. Following the logic obvserved in the arterioles, we expect the blood pressure to be lower in the capillaries compared to the arterioles. Since pressure is a function of force per unit area, (P = F/A), the larger the surface area, the lesser the pressure when an external force acts on it. Though the radii of the capillaries are very small, the network of capillaries have the largest surface area in the vascular network. They are known to have the largest surface area (485mm) in the human vascular network. The larger the total cross-sectional area, the lower the mean velocity as well as the pressure.[55] Reynold’s number also affects the blood flow in capillaries. Due to its smaller radius and lowest velocity compared to other vessels, the Reynold’s number at the capillaries is very low, resulting in laminar instead of turbulent flow.[59] The Reynold’s number (denoted NR or Re) is a relationship that helps determine the behavior of a fluid in a tube, in this case blood in the vessel. The equation for this dimensionless relationship is written as:[56] †¢ Ï : density of the blood †¢ v: mean velocity of the blood †¢ L: characteristic dimension of the vessel, in this case diameter †¢ ÃŽ ¼: viscosity of blood The Reynold’s number is directly proportional to the velocity and diameter of the tube. Note that NR is directly proportional to the mean velocity as well as the diameter. A Reynold’s number of less than 2300 is laminar fluid flow, which is characterized by constant flow motion, whereas a value of over 4000, is represented as turbulent flow. Turbulent flow is characterized as chaotic and irregular flow.[56] Disregulation disorders of blood pressure control include high blood pressure, blood pressure that is too low, and blood pressure that shows excessive or maladaptive fluctuation. Overview of main complications of persistent high blood pressure. Arterial hypertension can be an indicator of other problems and may have long-term adverse effects. Sometimes it can be an acute problem, for examplehypertensive emergency. All levels of arterial pressure put mechanical stress on the arterial walls. Higher pressures increase heart workload and progression of unhealthy tissue growth (atheroma) that develops within the walls of arteries. The higher the pressure, the more stress that is present and the more atheroma tend to progress and the heart muscle tends to thicken, enlarge and become weaker over time. Persistent hypertension is one of the risk factors for strokes, heart attacks,heart failure and arterial aneurysms, and is the leading cause of chronic renal failure. Even moderate elevation of arterial pressure leads to shortened life expectancy. At severely high pressures, mean arterial pressures 50% or more above average, a person can expect to live no more than a few years unless appropriately treated.[60] In the past, most attention was paid to diastolic pressure; but nowadays it is recognised that both high systolic pressure and high pulse pressure (the numerical difference between systolic and diastolic pressures) are also risk factors. In some cases, it appears that a decrease in excessive diastolic pressure can actually increase risk, due probably to the increased difference between systolic and diastolic pressures (see the article on pulse pressure). If systolic blood pressure is elevated (>140) with a normal diastolic blood pressure ( Blood pressure. (2017, Feb 22).

Sustainability Marketing Essay Example | Topics and Well Written Essays - 2000 words

Sustainability Marketing - Essay Example While economic pressures govern organisational strategies, their social responsibilities have also assumed increased significance. Widespread focus and attention on the issues of corporate social responsibilities and sustainable growth aspects have shaped new governance policies and practices. Such perspectives define the role organisations can play in creating responsible economic, environmental and social well-being of the communities they impact or serve. Several studies and observations made in this context have sparked debates on whether the marketing practices today are suited to an age characterised by environmental deterioration, scarcity of resources, expanding population and growing income disparities. Recent frameworks in this context are shaping innovative marketing practices that are founded on the principles of sustainability. A number of research studies have focused on explaining and exploring the concepts of sustainable marketing. This paper provides a deeper insight into the observations and conclusions provided by these studies and how it has contributed to the evolution of the concept of sustainable marketing practices. ... ion on Environment and Development’s report sustainable development is defined as the â€Å"development that meets the needs of the present without compromising the ability of future generations to meet their own needs† (World Bank Group website, 2001). Sustainable development relates to the ability of the organisations to balance the social, economic and environmental objectives. While economic objectives refer to industrial growth, individual needs, community requirements, and services social objectives refer to community empowerment, social mobility, cultural preservation, and equality. These needs and objectives should balance the environmental needs that encompass biodiversity, natural resources, ecosystem, pollution free air and water (Vagasi, 2004). Sustainable marketing remains an ambiguous term considering the paucity of extensive research in this area. Chen et al. (2009) define sustainable marketing as â€Å"the establishment, maintenance and enhancement of c ustomer relationships in order that the objectives of the parties involved are met without compromising the ability of future generations to achieve their own objectives† (p88). The essence of this definition can be related to the principles of sustainable development that are being incorporated by organisations across all disciplines for improved social and ethical business practices. The whole concept of green marketing or sustainable marketing is based on the principle of respecting the environment and considering social benefits as a distinctive part of the goods or services being sold in the market (Kotler et al., 2010). The essence of sustainable marketing practices is visible in various stages of product development, modification of existing products, changes in the production process,

Ethics at Coca Cola Essay Example | Topics and Well Written Essays - 500 words

Ethics at Coca Cola - Essay Example This reading of the social context allowed her to execute changes via the political platform by virtue of her leadership of the European Beverages Association. Her leadership of the association thus allowed for important changes specifically restricting marketing of coca cola and other softdrinks not only to make ethical changes in how to do business within her company but also industry-wide. Consequently, ethical changes made by Reiniche were wise with respect to the strategic advantage they conferred to Coke. Other beverage companies were moving in environmentally and ethically driven direction, so Coke could not afford to be left behind and thus, make the move instead a source of competitive advantage. Collaboration and effective communication with regulators, industry players and other non-governmental organization as shown by Reiniche is another facet of organizational leadership. The change initiated with respect to restricting marketing of softdrinks to children necessitated not only the efforts of one company but the collaboration of many concerned parties. Collaboration allows for easier facility of the implementation of the ethical agenda through support and the authoritative use of influence and power to make changes (it greatly helped for instance that Reiniche was President of the European Beverages Association that she welded power to lead the industry to make changes). Furthermore, collaboration only works with effectively communicating agenda to all concerned parties. Coke’s chief executive by Neville Isdell has communicated that ethical changes regarding operations to address environmental concerns are what Coke have in mind – with speeches as he did for the Worldwide Fund for Nature’s annual conference. In action, he has in fact led his company to collaborate with WWF to cut back and recycle the billion of liters of water it uses annually. Creativity and

Critical review of article - Essay Example This type of stereotyping has had adverse affect on men’s healthcare and alienated men from healthcare. He stresses the need for new healthcare and policies for men that are without any biases and tailored to need their particular requirements be they children, young men or grandfathers. Published by Earthscan in 2005, London J.J Macdonald’s book â€Å"Environments for Health† contains many arguments on the affect of social environments on health and in â€Å"A salutogenic approach to men’s health† (Ch. 6) he focuses on men’s healthcare. For Macdonald salutogenic health includes psychological and environmental factors, encompassing an interest in the lives of people: their physical, emotional, fiscal and cultural environment. Macdonald believes that any public health approach should address the needs for prevention of disease and access to health care of all categories including children, women, elderly people or men. He feels men’s health is a neglected field. He concentrates on the issue of men’s healthcare and the biases surrounding it. It is rather that in any population health approach one should adopt an overall systems look at the needs for prevention and access to care of different groups in their own right, whether children, women, older people or men. An objective view of the health needs and status of any population will lead to the inclusion of men’s health issues as a matter of course. He concentrates on the social position of men vis-à  -vis their health, how factors like stress, status, poverty, violence and gender bias negatively affect provision of necessary healthcare. (Macdonald, 2005) The first thing Macdonald notes is that men’s healthcare is focused on disease rather than men in general and that men are perceived to â€Å"behave badly† i.e. the general stereotyping of men is that they are violent, abusive and neglectful of their bodies and health..

Individual report - Be able to develop a communications process Research Paper

Individual report - Be able to develop a communications process - Research Paper Example These are basically computer based and internet linked. Social media has created a buzz in every industry. All industries including the airline industry has adopted the use of social media in their business and marketing process. The reason why social media gained the hype is that these media permit interactive exchange with the end users (Gerson, 2010). The exercise of this type of media in corporate internal and external communication has changed every aspect in airline industry. Emirates, a Dubai based airlines, wholly owned by the government of Dubai, has embraced social media approach for marketing and communication and also for crisis management when the airlines face bad weather conditions. In 2011, Emirates hired a digital agency that developed a Facebook page for the carrier. This was the initial step for the carrier towards the social media footprint (Rahal, 2010). The main goal behind this move is to develop a â€Å"touching connection† with the customers and contac t maximum number of customers who use airlines as their mode of travel. The initiative provided a platform for the carrier to make a channel for greater convenience through which the customers can reach the airlines. The brand became well known and prestigious among the mass and the carrier got brand loyal customers (Bilal, 2011). Emirates had also launched 29 whimsical animated ads in 14 languages to show the lighter side of language. The animated ads were the next step of the global airline’s â€Å"Share a Smile’ campaign and was the part of the global brand campaign known as â€Å"Hello Tomorrow† launched in April 2012. The ads featured crew members of Emirates who were expressing unusual greetings and expressions from all over the world. The â€Å"Share a Smile† campaign not only created communication of linguistic skills among the multilingual crew and international crew it also helped in building cultural understanding in a light- hearted way among st travellers (Kimberley, 2013). Task 3.2: Problems faced in communication process and ways to improve it The goal of advertising is not only to alter the demand curve but also to shift the curve upward and to the right. For an industry it means that it either brings in new customers in to the market or encourages the existing customers to use the service more frequently whenever needed. For an airline, the demand can increase if the passengers of competitors shift to their airlines (Kraft, 2003). This results in competitive advertising where all the airline companies are advertising to retain their market share. Some airline companies’ gives stress upon the reliability, comfort and convenience of air travel and some purely gives stress on the non-existent advantage that they have (Van, 2012). The advertisements in Facebook and the animated ads are provided by Emirates to give travelers specific information about the scheduling and the price. Though the advertisements in Face book and the animated ads attracted customers to the carrier but it failed to achieve success in long term because of the problem faced by Emirates (Shearman, 2011).The problems that are faced in the

Gun Control Report Essay Example | Topics and Well Written Essays - 1500 words

Gun Control Report - Essay Example Mostly, those involved in gun violence may not be gun owners, but might be individuals that have illegal access to guns. Generally, gun ownership tends to be strict upon civilians as many at times individuals with the intention of committing crimes acquire guns with relative ease through illegal means. Therefore, it is import that the government sensitizes the public on matters related to gun ownership before the actual implementation of gun control policies at the legislative stage of governance. Further, this report will give the various statics surrounding the reported numbers of gun related crimes within the urban setups as compared to those in rural areas. Ideally, the number of gun related violence in urban states where there are strict regulations on gun acquisition are higher than the rates in rural areas where gun acquisition is easy (Joe, 2012). Subsequently, the report will be in tandem with the practical approaches applicable in the minimization of gun related crimes at t he lowest level of governance to ensure that civilians also play a role in developing safer living environments. The report would also to address the impact of the castle doctrine laws in some states as possible contributors to gun violence.

Ideally, this aspect has made gun violence be the greatest contributor to the premature demise of the young population of America. On the other hand, the statistics on the number of reported non-fatal gun related crimes amount to close to three hundred and forty seven thousand cases with a minimal number of this people seeking treatment at hospital departments. In essence, the rate of homicide in America is seven times higher than that of other developed economies making it a worrying trend for a good performing economy (Sowell, 2012). Fundamentally, the lack of proper gun laws is the prime reason as to why there is a higher prevalence of gun ownership and higher cases of gun related violent crimes. Further, gun viole nce also impacts the economy as the US population loses a significant number of the work force to violent deaths while the rest incurs expenses in seeking treatment for the injuries caused by gun violence. The traumatic effect caused by gun violence tends to have an impact on the increase of poverty levels as it tends to influence psychological imbalance for those affected by this tragic event. According to statistics, the average direct or

See the topic on the file that i send u - Essay Example Larmor equation originates from the classical physics and uses specific magnetic field strength. The equation aids in computation of the resonant frequency of the precession (Kamel and Merkle 2011, 102). Larmor equation is significant since it the frequency at which the underlying nucleus ought to absorb energy (Bacchieri and Giovanni Della Cioppa 2007, 56). The process of absorption of energy makes the proton change its configuration and ranges from one to one hundred MHz within the MRI. This paper illustrates the impacts and limitations of the higher B0 3T and 1.5T imaging providing imaging in regard to the Larmor formula. Numerous impacts associated with relocating from lower to higher field strength in regard to the imaging. The different normally result from the Larmor frequency, wavelength and the specific absorption ratio (Weir 2011, 69). Moreover, the primary delinquent pertains to the escalation within the excitation rate of recurrence ? of Larmor equation: ?0 = ? B0 Where ? 0 = the angular frequency of precession of protons within an external magnetic field, ? = gyromagnetic ratio=42.58 MHz/T i.e. ? = 2.67*108 radians s-1 T-1 B0 = the strength of the external magnetic field Thus, the timbre frequency escalates from roughly 63.9 MHz at the rate of 1.5T to corresponding 127.8 MHz at 3T. For computation of the wavelength within the water and the velocity of light is equivalent to 3.0?108M/s over the prevailing echo frequency. The dielectric constant of H2O into consideration: .The wavelength within liquid diminishes from fifty two centimeters at a range of 1.5T to corresponding twenty six centimeters at a range of 3T (Kamel and Merkle 2011, 115). Relative diminutive wavelengths are nearer the ordinary physique diameters and result to a gain of protective impacts. It also results to intrusions of overlaid RF surfs possessing multifaceted impacts on the RF consistency. The related complications are predominant within the front and lumbar imaging processes ( Bacchieri and Giovanni Della Cioppa 2007, 56). Rectification of an imaging problem takes place via RF shimming and advancing coil design. Absorption ratio associates to the corresponding square of excitation frequency that affects the square B0 field strength (Vittinghoff 2012, 65). The Larmor precession rate of recurrence is the degree of the precession of a swirl package within the magnetic field power. The rate of recurrence of the RF pointer stimulates alteration within the nucleus spin energy level. It also determines the gyromagnetic proportion of atoms and strength of the underlying magnetic meadow. Thus, stronger magnetic fields will result in higher precessional frequency (Kamel and Merkle 2011, 95). RF rhythm of the Larmor rate of recurrence is the applicable core atom and protons, which changes configuration of track of the principal attractive field. The rearrangement of the positive ion to the chief attractive field results in the emission of energy at the Larmor freque ncy. Attractive field variation across the magnetic field slope results in deviation of the Larmor rate of recurrence (Weir 2011, 85). Chemical shift scale is directly proportional to attractive field strength. Thus, plump and liquid resonance rate of recurrence normally contrast via the two hundred and twenty hertz at a range of one point five tesla and corresponding four hundred and forty

How Information Flows Within an Organization Essay Example for Free

How Information Flows Within an Organization Essay Information has to travel through different types of pathways in order to be received and used. Think of the pathways of information like the transit system. Information is loaded into systems by using input devices, like keyboards or touchscreens. After the information is imputed it is transferred to some type of storage medium, whether hard disk drive, RAM, or CD’s or DVD’s. Once this information is transferred it is then able to be accessed and used as long as the correct permissions are assigned. The storage allows for future access and the ability to retransmit the data to another device, by using the LAN, WAN, Internet or removable devices like flash drives or external hard drives. The ability to create and use information would not be possible without the hardware that allows the user to input the information they want others to read or use. It can go down to basic components like computers, keyboard, hard drives, etc. However, in conjunction with the hardware there has to be software which outputs the data so the user can read it. Once the data is read the user can create databases or upload the information to different locations like a cloud based server. Once again with the ability to do this would not be possible without special types of hardware that allows this. The hardware in reference is NIC cards, routers, switches, hub, etc. All of these things make it possible for information to be transmitted around the world. Of course to simply transmit data and information around the world could be a very simple thing, until you add in the steps necessary to protect the data. In my current job we do not use very much resources to transmit data or even  create it. However, a company that we work for uses networks and even special communication cables to transmit and receive data from different devices within the building we are working. Basically there are controllers that connect via a two or three conductor cable and which connects to devices mounted on air handler systems. These devices take in an enormous amount of complex data and regularly transmit the data to the controller which then relays the information to a computer that is on the mainframes network. This network allows the company the ability to have remote access to the controller which allows them to be able to change certain values in order to make the air handlers run more smoothly. Some of the data that is transferred include, outside air pressure, discharge air temp, return air temp, and there are even safety measures transmitting to ensure smooth operation. Once an alarm is triggered the device sends data to the controller which then relays the alarm to the computer which outputs the reason for the alarm and specifies what triggered the alarm. A technician can then go on the computer and adjust whatever values need adjusting to remove the alarm and resume proper operation. Without this network of devices and controllers and computers there would be no way for these issues to be resolved in a timely manner. Seeing how allot of the work we do is in Charlottes main healthcare system, by us not being able to have quick and painless connectivity many peoples wellbeing could be at risk. The one thing the company I work for makes sure of is security for their systems and networks. Although the physical network is not part of the company’s infrastructure it is protected from other people trying to access it because it is their equipment, cables, controllers, and devices. The hospitals have no access to these systems because one wrong value can be the difference between freezing temperatures or summer conditions in the building. The company, Johnson Controls, uses three different programs that have to be authenticated before access is granted. Firstly the technician has to slide their finger over the fingerprint scanner to access the computer that connects to the controllers. Seems like a correct finger scan would be all that’s necessary for accessing the system, however, the IT personnel decided to add two more layers of security due to the nature of their business. Secondly the technician has to scan their badge into a card  reader type of device that pops up a screen that greets the technician as a Johnson Control employee. Once again not enough security in the minds of Johnson Controls so the final security measure is an encrypted password, that if it is entered incorrectly starts the whole process over again. After talking with multiple technicians the consensus is that they cannot stand all the security measure, but they do understand the purpose. Perhaps the best measure the company has against potential invasions is that all the equipment they use from top to bottom is made by themselves. This ensures that only their employees are trained and permitted to use the equipment. Other people might look at the equipment and be dumbfounded due to the processes and certain protocols in place on how to use the equipment to access any information. Although I currently do not work in an environment that utilizes servers and multiple computers, I do see how information is passed through devices to controllers and finally to computers or networks. Even though there is multiple types of information the way it is used and flows follow the same path. Without hardware and software there would be no way to use and transmit the data. As the technology continues to change and become more advanced, I am sure the way information is used will change along with it.

Impact of Festivals

Impact of Festivals Robyn Ormond Introduction: South Africans love festivals, it is a chance to ‘let loose’ and enjoy a time of fun, family and by the end, usually no funds. Festivals can be described in many ways, namely â€Å"events of limited duration developed primarily to enhance the awareness, appeal and profitability of a tourist destination† (Ritchie, 1984: 2). Festivals have become a vital component of tourism in small towns (Visser, 2005). The importance of annual festivals in two South African towns, being Sedgefield (the Sedgefield Slow-Festival) and Knysna ( Knysna Oyster Festival) as well as the economic importance of these festivals will be explored to show how festivals can prevent the decline of these iconic towns. Decline def The Importance of Festivals Festivals are more than just a way of making money, there is a deeper impact of festivals upon the communities who host them, these festivals can then rather be referred to as â€Å"a public, themed celebration† (Jackson et al, 2005). Festivals which occur in smaller town like the two that will be analysed normally have a strong sense of community and by holding a festival, ideals such as leadership and accountability of the locals are promoted, members of the community are encouraged to get involved and to take responsibility with regards to the planning and running of the festival (Visser, 2005). This act of holding a festival strengthens the community and allows for bonds of friendship to form between the town members as community goals are achieved through the management of the festival (Saayman A, Saayman, M, 2006). The festival also allows for the natural beauty of the towns to be appreciated and act as a platform for conservation and environmental protection (especially in Sedgefield and Knysna, both of which occur along South Africa’s prestigious Garden Route) (Visser, 2005). Festivals not only create links within the community but strengthens ties with that of the world around them (people from much larger cities- Cape Town and Johannesburg are willing to travel to come and participate in the festivals held in Knysna and Sedgefield.) (Saayman A, Saayman, M, 2006). The strong community bond a festival creates can help prevent the town from going into decline by becoming an attractive place to live and especially to retire to. The Economic Importance of Festivals: Not only are festivals important for growing a town’s identity but these celebrations are known to bring a healthy influx of money into the town. Festivals can boost a towns economy by either extending the current seasonal income (money made during peak tourism times in the town- usually correlating with holidays) or by creating an entirely new tourism season (Visser, 2005). The economic impact of a festival on a small town is simple; people come from outside the town and by participating in the festival, spend money which goes directly towards the local economy of the town (Saayman A, Saayman, M, 2006). Tourism is the driving force behind a festival and the more a town can offer in terms of tourism, the more attractive the festival will be. Festivals are a way of a town advertising itself to the outside world in the hopes of attracting people willing to settle there or foreign investors to take an interest in the town (Saayman A, Saayman, M, 2006). The money generated from a festival is used in a small town to help ensure sustainability of the town and to help the town regenerate (if it had previously gone through a period of decline) (Saayman A, Saayman, M, 2006). A tourist spending money in the town during a festival has an impact on a variety of sectors due to the interlinked nature of the tourism industry (a tourist will need to purchase food and drink during the festival, have access to accommodation as well as pay to participate in the events of the festival, this will benefit a large number of businesses in the town) (Saayman A, Saayman, M, 2006). For the two festivals bei ng explored, a large portion of the proceeding is donated to charity, as the community of Sedgefield and Knysna are more people-orientated and less money-driven. The Sedgefield Slow Festival: The Sedgefield slow festival is a celebration of life in a small town only 7.85 km ² in size with a population of 8286 (Firth, 2011) along the Eastern Cape of South Africa. The town advertises itself as South Africa’s self-proclaimed â€Å"Slow Town† (as nothing will happen at a speed faster than a tortoise’s walk- the icon of Sedgefield). The local residents volunteer to be part of a committee who are dedicated to creating a festival which promotes â€Å"Wholesome goodness, Family, Friends, Fun, the Outdoors and Great food† (Dixon, 2014). The festival is young in comparison to other South African festivals with its birth in 2010. The objective of the festival is to show off the natural beauty of the area in a way that will get the entire town involved while creating local economic opportunities at the same time (Dixon, 2014). The town hosts several events during the festival including the infamous â€Å"Anything-That-Floats Race† (a water race where participants must build crafts constructed entirely out of recycled materials). Other events include a Beer-Pong competition held at one of the local bars as well as the Town Hall Arts Exhibition. In total there are about twenty five events held over the three days surrounding the Easter weekend (18-20 April in 2014) (Dixon, 2014). In 2013 the proceeds from a variety of events, market sales (in the local farmers’ and craft market) and donations, the Slow-festival was able to support four different charities (Sedgefield Hospice, Sedge Mobile Meals, KAWS and Masithandane) with R12000 over the three day festival (Dixon, 2014). The Knysna Oyster Festival: Only 25km away from Sedgefield is the town of Knysna. Every year around the first week of July the Pick n Pay Knysna Oyster Festival is held over a ten day period (Knysna Oyster Festival, 2014). This festival is much older than the Sedgefield Slow-Festival with its debut in 1983. The purpose of the festival was originally to bring people to the area during the off-peak winter period; subsequently the festival has experienced a large amount of success and has grown significantly since its origin (Knysna Oyster Festival, 2014). The festival places a great emphasis on supporting charities, and due to the large nature of the festival, a sizeable amount of money can be donated. In 2013 the festival was able to generate R1 million which would benefit the community and have a significant impact on the local charities (Knysna Oyster Festival, 2014). Before an event can be registered as an official event of the Oyster Festival it must first state which charity or non-governmental organisation it will be supporting with a portion of its proceeds (Knysna Oyster Festival, 2014). Out of the many events held over the ten days, the three most iconic are the Momentum Weekend Argus Rotary Knysna Cycle Tour (which is one of the largest road and mountain bike races in South Africa), the Momentum Cape Times Knysna Forest Marathon and Half Marathon and of course the oysters which are eaten over the duration of the festival (which can reach up to 20000 oysters consumed) (Knysna Oyster Festival, 2014). Conclusion: Festivals in small towns (especially in South Africa) are events in which the entire community can be involved in the planning, managing and running of the festival. These festivals are able to boost the local economy and generate a flow of capital in times which would otherwise be regarded as off-peak quiet periods characterised by little tourism and lower income for the community members. These festivals such as the Sedgefield Slow-Festival and the Knysna Oyster Festival create an identity for the town whilst forming community bonds between the residents. The large charity component of both the Sedgefield Slow-Festival and the Knysna Oyster Festival allows for all in the community to benefit from the proceeds. Overall festivals are a time to celebrate life, family, food and of course to have some fun. Reference List: Dixon, A. (2014). Sedgefield’s Slow Festival.

holocaust and lunatic fringe :: essays research papers

Behrens and Rosen asked, â€Å"What sort of people were responsible for the Holocaust, and for the long list of other atrocities that seem to blight the human record in every generation? Is it a lunatic fringe, a few sick but powerful people who are responsible for atrocities?† and the responded with â€Å"If so, then we decent folk needn’t ever look inside ourselves to understand evil since ever lurks out there.† Behrens and Rosen use this to construe that evil does not lurk only in lunatics but the ordinary person as well. Everyone is capable any act possible, the circumstances and the environment play an important role on what a person is capable of doing. Doris Lessing uses this to state that individuals will conform to the majority because of society’s pressures and lose individualism. Lessing uses the fact that because of western societies are well educated in different ways, free to make choices that this makes the individual, but people never think to look at their lives and see that they are no longer and individual because they are conforming to the pressures of society. She uses the fact that people often socialize with â€Å"like-minded† people often forces to make decisions that our peers make. She declares that, â€Å"We find our thinking changing because we belong to a group. It is the hardest thing in the world to maintain an individual dissident opinion, as a member of a group.† She goes on to review several experiments that involved conforming to groups.   Ã‚  Ã‚  Ã‚  Ã‚  Stanley Milgram’s experiment shows that people many times conform to do what an authority figure says or orders. Despite moral apprehensions, a person might continue to do what they know is wrong. Milgram used ordinary people of all different types of life in his experiment and showed that many of them will continue until they are told to stop. It is not a â€Å"lunatic fringe† that will go against what is morally right, but it is a majority that will. Milgram says that it is easier going against one’s own principles then disobeying an authoritative figure.   Ã‚  Ã‚  Ã‚  Ã‚  Milgram’s results and Behrens and Rosen’s argument, as well as Lessings all demonstrate each other. Milgram shows that it easy for people to go with authority, Behrens and Rosen state that it is not a lunatic fringe but instead ordinary people, and Lessing saying that people will conform to groups.

The Joy Luck Club: Movie versus Book In the novel, The Joy Luck Club, by Amy Tan, it tells of four Chinese women drawn together in San Francisco to play mah jong, and tell stories of the past. These four women and their families all lived in Chinatown and belong to the First Chinese Baptist Church. They were not necessarily religious, but found They could improve their home China. This is how the woo's, the Hsu's, the Jong's and the St Clair's met in 1949. The first member of the Joy Luck Club to die was Suyuan Woo. Her daughter, Jing-mei "June" Woo, is asked to sit in and take her mother's place at playing mah jong. Memories of the past are shared by the three women left, An-mei Hsu, Lindo Jong and Ying-ying St Clair. June Woo learns of the real secret her mother carried to her grave from her mother's friends. The twin baby girls, her half sisters, Suyuan pushed in a Wheelbarrow as she escaped from the Japanese. Due to sickness, Suyuan can no longer carry her babies, and is forced to leave them on the side of the road. She lives her whole life not knowing if they are alive or dead. In the book, the Woo's left for America to build a better life for themselves. Suyuan Woo wanted to have a daughter like herself, and no one would look down on her. It was important that she speak perfect English and hopefully not share in the same tragedies and sorrows she had known. The movie brought this concept out very vividly. You were able to imagine the time and place and the emotions of the characters. Their anger in the early years, how women and children were treated as possessions. The book spoke of Rose Hsu Jordan, daughter of An-mei Hsu, who had seven brothers and sisters. A very tragic time in her life when her brother Bing drowns at age 1 while she was in charge of watching him. The movie does not touch upon this tragic event and brings out the rich family Rose marries into, and the instant rejection from her boyfriends mother. Rose unhappiness in her marriage with Tod, is similar to the unhappiness her mother had throughout her life. Lindo Jong was a special character in the book , referring to promises she made to her mother as a young girl, and keeping them throughout her life.

The types of pyrotechnics materials used include flash powder, flash paper, gun cotton, black powder (gunpowder), smokeless powder, detonator explosives, and many more. They are used in bullet hits (squibs), blank cartridges, flash pots, fuses, mortars, smoke pots, sparkle pots, etc. The main problems of pyrotechnics include prematurely triggering the pyrotechnic effect, use of larger quantities or more dangerous materials than needed, causing a fire, lack of adequate fire extinguishing capabilities, and, of course, inadequately trained and experienced pyrotechnics operators. As a result of these risks, all pyrotechnics special effects are regulated at the federal, state and local level. In general, all pyrotechnics are explosives, but not all explosives are pyrotechnics. Class A explosives (high explosives) are materials like dynamite and Primacord which may detonate even if unconfined. Pyrotechnic special effects materials are Class B explosives. They will burn, but not explode unless confined. Examples are black powder and pellet powder, safety fuses, igniters, igniter cord, fuse lighters, Class B special fireworks, and Class B composite solids propellants. Class C explosives are common fireworks. Note that short lengths of Primacord may be classified as Class C under certain conditions. Both Class B and C explosives are also called low explosives. All pyrotechnic materials and other explosives consist of an oxidizer (source of oxygen) and a reducer (fuel). Examples of oxidizers include potassium nitrate, strontium nitrate, potassium perchlorate and potassium chlorate. Examples of fuels include metals like magnesium and aluminum, sulfur, silicon dioxide, and organic fuels like charcoal, starch, resins, and chlorinated hydrocarbons. The choice of fuel and oxidizer determines the type of effect (flash, smoke, sound, etc.) its color, and its intensity. There are two basic types of pyrotechnic materials: single component and two component systems. Single component materials will either burn if ignited, or explode if ignited when enclosed, since the oxidizer and fuel are in the same mixture. Flash paper, for example, is a partially nitrated cellulose and contains both fuel and oxidizer internally. The traditional black powder has potassium nitrate as the oxidizer, and sulfur and charcoal as fuels. In two component or binary systems, the oxidizer and fuel are separate components which are transported and stored separately and only mixed when ready to use.

Background check of hiring employee Essay

In nowadays, background check of hiring employee is practicing by almost all agencies. Point is that, the skills of the applicant can be, somehow, figured out. It is much more difficult to assess the level of trust, honesty, mental toughness, and loyalty. Reading through chapter 9, and conducting a slight research, my answers to the questions of the given scenario are as follows: 1.Do temporary agencies have a â€Å"duty† to run background checks? If so, did Robert half â€Å"breach that duty?† Why or Why not? According to the law of negligence, temporary agencies should follow the duty policy on background check on pre-employment, in order not to satisfy an element of negligence. In case of Robert Half International Inc., and Fox Associates, Inc., I don’t think, that duty was breached, the company trusted to provided information by Ms. Ross about herself, and she got good recommendations from her former employers. At some extend, it is a background check. 2.The court ruled against Fox Associates. Was the court correct? Do you think Fox should have done its own background check? Why or Why not? I agree with the court decision, that it was determined that duty is not breached, because it happened unknowingly. Even though the company recommended the employee, Fox could do its own background check as well. 3.The fact pattern mentions that Sunbeam suffered similar damages when it failed to do its own background check on Mr. Dunlap, its former CEO. Who was more at fault, Sunbeam or the Executive search agency? In this case, the fault has an Executive search agency more, than Sunbeam, as it its straight duty to check background before approve for hiring. However, Sunbeam is liable for its losses also, because it should request and check the information about hiring employer. 4.Strategically and legally speaking, why do you think the former employers said nothing about Ms. Ross’ history and gave her good recommendations? There could be some reasons: 1). the former employers might feel sympathetic towards Ms. Ross, and they don’t believe that she has stolen any funds; 2) Ms. Ross, indeed a good specialist in her field; and the last 3) The former employers just didn’t tell the truth. 5.Develop one  unique background check policies for your company on employees hired through a search firm or temp agency. The main idea on background check which I’d like to develop, besides gathering information, confirmation of address, criminal records searches, is that pre-employee will answer some â€Å"simple† questions, which will ask him/her the same, but in different manner, and maybe I would add some psychological tests, which will let me know if that employee was capable to do something unethical in his past work experience.

Australian education trends Essay

It is often known that education forms the backbone of economic development and growth in any nation. The investment in pre-school, primary and secondary education as well as community college education ensures availability of human capital endowed with relevant skills and knowledge for enhanced productivity. This has proven to be a necessity for sustained economic development in any country in the world. Educated people are in no doubt different from the uneducated or less educated in a variety ways (Tiffen, & Gittins, 2004). At the outset, the difference is eminent in attitudes and behavior, in their well being and health status, income as well as values regarding morals, religion, politics and employment among others. By instilling these positive characteristics to individuals in the community, education has therefore transformed the world people live in from the old ignorance-ridden era to the technologically-advanced modern life (Tiffen, & Gittins, 2004). Australia has experienced a steady increase in education levels in the last century. The government has in the past centralized funding of education and imposed high taxes on high income earners in an attempt to finance education. Students are not spared either in this plan and have been included in the â€Å"user pays† principle where they reimburse for the education services received. However, this scheme has affected education in many countries and how the government plans to implement the principle together with high taxation is a matter of concern. In Australia, the Government provides public funding for non-government schools as well as substantial assistance to government academic institution. Funding of state government schools is the primary responsibility of States and territories (Laporte, & Ringold, 1997). These organs can also provide assistance to non-governmental institutions of learning. It is estimated that more than two thirds of the students in non-government academic institutions are affiliated to Catholic as a religion. Australian education system is a three tier model where children enroll in Kindergarten at the age of about five years, then graduate to primary followed by secondary levels from year one to twelfth year and finally tertiary education (Harrison, 2002). Education is mandatory for the children aged between five to about sixteen years but the federal government caters for the university education. This system has ensured a reduced school life expectancy thereby enhancing educational development in the country (Centre for Educational Research and Innovation, 2008). This however draws a sharp contrast to the old system. Australian education system was highly stratified and that only infants and primary education were provided for the children. Additionally, Selection for high school education was very competitive, and favored the siblings of specific people who used to be prominent in the society (Henry, 1990). These individuals included industrialists, agriculturalists as well as businessmen among other professionals. Teaching profession was undermined since the government offered low wages to the teachers in addition to subjecting them to strict laws that restricted their personal as well as professional conduct. These factors reduced the productivity of the teaching staff thereby suppressing students’ performance in schools (Henry, 1990). The tremendous increase in level of education in Australia has been largely attributed to changes in a variety of factors including social and institutional framework as well as economic changes and student financing much else besides (Evans & Kelley, 2002). To start with, changes in educational levels have been associated with urbanization. The rural-urban migration brought about by the inadequacy of farmland as well as search for skilled jobs in the cities has enhanced the development of cities in Australia. This has therefore called for the provision of educational services in these highly populated regions hence increasing the educational levels. Evans & Kelley (2002) estimates the changes brought about by urbanization to about six percent over the last century. Economic growth on the other hand has been articulated with the steady increase in the educational levels in Australia. This country has witnessed a considerable economic growth in the recent past. Australian GDP for instance is currently valued at 1050 billion dollars which is slightly above 1.6 percent of the world economy (Laporte, & Ringold, 1997).   Australia has so far recorded steady economic growth and unlike other OECD nations it did not fall to the economic recession witnessed in the recent past (Organization for Economic Co-operation and Development, 2007). Moreover, the country has recorded a growth rate of about 3.6% annually for the last fifteen years. This has empowered the government hence its ability to fund education as well as other sectors (UNESCO/OECD World Education Indicators Program, 2005). It therefore implies that most of the Australians are able to access education compared to the past where parents used to dropout of school after compulsory education level. The current parents have therefore acquired high social status in addition to pursuing the available high skilled and well-paying professional jobs. The Australian children who hail from well educated families can now access proper education thereby increasing the levels of education in the country (Ruitenberg, 2010). Economic growth has therefore contributed to about twenty six percent education growths in Australia. This change has mainly improved education levels in both the primary education which is compulsory as well as secondary education which the educated and socially as well as economically-empowered parents can now afford (Evans & Kelley, 2002).The duo however admit that the aforementioned factors only contribute to a little percentage of the sources of educational transformation so far witnessed in Australia and that the real sources of change in education trend in this century are still unclear. Youth participation in education including vocational education and training has also improved in Australia. According to Sue et al (2009) a variety of factors have influenced this upsurge in the education trends in Australia. Factors such as how the young people’s families as well as community value education, the socioeconomic status of the general population, available education and training and the school curriculum, existing policies on education and youth employment, financial incentives and obstacles, economic structure in regard to industry and occupation have changed hence improvement of youth participation in education and vocational training in Australia (Kilpatrick, Sue,  Baynes, Chapman & Hazel An indexing term that provides specific identifying information in a category: geographic names, laws and legislation, or tests and testing., ()), 2009). Australia just like other developed States has recorded a steady decline in fertility rate which has brought about the ratio of two children per couple (Tiffen, & Gittins, 2004). It is always presumed that the higher the number of children in a family the reduced ability of the parents to provide quality education to an individual child. This is because the available resources such as finance, energy and time are shared among the many children thereby reducing the amount received by an individual child (Evans & Kelley, 2002). The reduced fertility rate in Australia has ensured reduced number of children in a family which the parents can afford to provide quality education for thus contributing to increased level of education in the country. These changes in education levels brought about by changes in family size are only noticeable in secondary schools and tertiary levels and not in primary level where the government funds education (Harrison, 2002). The government’s commitment to provide quality education has also influenced to a greater extent the steady growth in education levels so far witnessed in Australia. The Australian government has increased its spending on education of both males and females compared to the last century. There have been issues of gender inequality in education and females have been stereotyped as underperformers in the past (Evans & Kelley, 2002). It is note worthy that in all countries except New Zealand; there have been lower performance by females than their male counterparts especially in mathematics literacy (Marginson, 1993). This traditional stereotype is being overcome by the Australian government through equal provision of educational services to both the sexes. Philosophers such as Martin Roland have also contributed to this issue of gender equality and education of the girl child. Roland argues that the old tradition was a barrier to the equal distribution of resources to both the sexes in the society since it discriminated against the females and favored the males. She reiterates that gender issues should be embedded in the curriculum as well as in teaching and schooling activities to ensure that the product of such a system is an ideal educated person. John Dewey is another renowned philosopher whose contribution to education, politics as well as philosophy has been globally recognized. According to Dewey, education was the cornerstone to intellectual development and progress of the society. He stressed on the improvement of moral and social nature of schools as an attempt to fostering democracy and community prosperity (Paringer, 1990). Dewey asserts that provision of education service to a single child in the society empowers the child towards self- effectiveness which consequently provides a guarantee to a lovely, worthy and harmonious society. Democracy never used to prevail in the ancient society as a result of lack of knowledge by then. According to Dewey, the nature of things should be viewed from a perspective of change and growth and therefore the continuous transformation in education is inevitable (Dewey, 2007). Nel Noddings is an additional prominent philosopher whose argument revolves around the moral reasoning, beliefs and values in education. She states that the current education trends encourages moral development hence the need to adopt educational structures that incorporates ethics and the use of motherly interest to inform moral learning. She however blames politics that fulfills the interests of particular groups for threatening the establishment of strong ethical foundation of learning as well as teaching in the academic institution (Palmer, Bresler, & Cooper, 2001). Conclusion Education in Australia has undergone commendable changes since the first half of the last century. The Australian government as well as other stakeholders in the educational sector has contributed towards the social progress which is primarily dependent on the enhanced education standards in the country. Education has so far transformed from the old system characterized by repugnant traditions and values to the modern technologically- advanced era where education is the basic requirement for community sustainability. The progress in science and technology in the current era has created the knowledge and skills necessary for the developed industrial economy, while growth of education has provided workforce that is needed to utilize these new opportunities. Australia currently enjoys a socially-friendly environment with high paying professional jobs as well as improved living standards courtesy of development witnessed in the education sector.
