3(S) - Essay Example sis, human resource management is a very important element in a business or public organization, as it will ensure that the organization under consideration has highly skilled and efficient employees. This in turn will make the organization to serve its customers in an efficient manner, leading to the achievement of the goals and objectives of the organization under consideration. The government of the United Arabs Emirates has realized on the importance of human resource management. In a bid for the government of the United Arab Emirates to decrease unemployment, and increase the efficiency of its work force, the government has come up with a series of policies aimed at addressing these issues (Werner and DeSimone, 2012). One such policy is the emiratisation of the country’s economy. The government of UAE developed this program, in order to train the citizens of the emirates to be highly competitive employees, and this is through the introduction of a good education system, and sponsoring seminars and trainings that focus on the abilities, skills, and competencies that are needed by employers in the Emirates (Yamamoto, 2013). The intention of this program is to recruit nationals who are in the private and public sector in a manner that is efficient and meaningful. Since the inception of this program, the public sector has made great steps in making this program a success. However, the private sector hasn’t made any progress, with statistic indicating that the citizens of UAE only occupy 0.5% of the total workforce in the private sector. Based on this background, the goal of this paper is to develop an efficient human resource strategy for the government of the UAE. This paper aims at achieving this goal by analyzing the various human resource strategies of the UAE, identifying their weaknesses and strengths. This paper mainly concerns itself with analyzing the emiratisation program of the UAE, and this is because it is the main human resource strategy of

The Mechanics of Spontaneous Healing Essay Example for Free

The Mechanics of Spontaneous Healing Essay The field of holistic healing is an evolving discipline. Therefore, the words used to speak about the realm of holistic healing remain difficult to concretize. For those who view this growing field from a distance, the confusion about communication is apparent. Essentially, the same words are used in different ways, depending on the speaker and on the context. Even practitioners within the field of holistic healing use words like â€Å"healing† and â€Å"holistic† in idiosyncratic ways. For holistic medical doctors, the term â€Å"holistic† may mean incorporating alternative healing techniques or procedures such as the use of herbal remedies, diet and nutrition. For psychologists â€Å"holistic† may indicate their use of several therapeutic techniques within the discipline of psychology. Or it may indicate that they integrate other healing techniques such as bodywork or meditation within the context of psychotherapy. For some, the term â€Å"holistic healing† denotes an overall philosophy of integrationalism regardless of their respective training background, and as such, serve as a self-identifier. Given the disparity of meanings attributed to the words, the realm of holistic healing is fraught with communication difficulties. This search terms clarifies for the operational definitions of the study’s critical terms to avoid confusion and help set the limits of its purview. Holistic healing literally means wholeness (holy and heal both derive from the Anglo-Saxon healen, meaning whole), with all that implies: â€Å"Bringing the rejected and discarded into the circle; listening with the inward ear for those parts that have been silenced; seeking a deeper, more accurate, more creative engagement with the world around us† (Barasch, 2003, p. 7). â€Å"Holistic† refers to the acknowledgement that human beings are multi-leveled. We exist each moment as a body, mind, spirit/soul, and emotional beings. Holistic healing therefore, acknowledges the many parts of our being and seeks to understand their interactions in both the disease and the health creation process. Holistic Healing Conceptualized Holistic healing remains on the edges of mainstream scientific thought. It is contrary to the accepted view that we will always be able to find a specific cause for any given disease. Holistic healing deals with the totality of a person’s being: the mental/emotional, physical, social, and spiritual dimensions. It is this totality as an integrative and synthesizing force, so perceived and utilized by the healing person or team, that constitutes holistic healing. (Otto Knight, 2001, p. 3). Holistic healing was described by Pelletier (1997). For him, all states of health were psychosomatic, each person representing a unique interaction of body, mind, and spirit. Illness was a disturbance in the dynamic balance of these relationships. The client and the practitioner shared the responsibility for the healing and both creatively learned about themselves during the healing process. Practical screen In spite of a thorough search of the literature, no studies have been found that relate directly to the focus of this study, the mechanics of spontaneous healing. The literature review is not the theoretical foundation on which the study is based, but is presented in order to illustrate the current state of the relevant literature. The initial review established the appropriateness of this study. The majority of the review will be accomplished after the data is analyzed and it will be guided by the findings. Literature from both the initial review and the later review will be compiled in this section. Topics will also be discussed that might relate to the mechanics of spontaneous healing such as the experience of healing, health status, recovery, and survival. In this related literature the independent variables such as social support, optimism, and hardiness are often well defined with reliable and valid measures. The dependent variables such as â€Å"being healthy, having minor health problems, suffering from chronic disease, being disabled, and being dead are treated as equally-spaced points on a continuum† (Hobroyd Coyne, 2002, p. 364), and are often well-defined or measured. Other measures sometimes defined as â€Å"healthy† are help seeking behaviours and compliance with medical recommendations. Nevertheless, there are some interesting studies in which attempt is made to measure the factors that might be relevant to the mechanics of spontaneous healing. The popular literature claims much more knowledge than can be substantiated with valid research but this literature has stimulated a research interest that may lead to more knowledge about the mechanics of spontaneous healing. In the literature related to specific techniques, such as biofeedback, therapeutic healing touch, imagery, and hypnosis is discussed directly. Each of these areas has a body of research but the studies do not define healing and often do not give enough information for the reader to make judgement on the mechanics of spontaneous healing and on whether the outcomes are credible. Methodological Screen A suitable design for exploring holistic healing from the perspective of the person in the mechanism of the health creation process is phenomenology. Phenomenology is the study of the essence of human experience (Solomon, 1980). Phenomenology is based on careful consideration of rich complex data, using logic and insight (Cohen, 2001). The phenomenon studied need not be tangible in a physical sense as it can be such things as loving, thinking, imagining, calculating, or doubting. Healing falls somewhere between with both tangible and intangible elements. Cause and effect are not relevant, but it can be asked what the experience is of perceiving something apparently causing something else. One would not ask what causes healing, only what the experience of healing is. As an approach to research, it is a way to stand back and watch, to break out of one’s familiar acceptance of the world, and to attain a state of wonder and understanding (Merleau-Ponty, 1992). Phenomenology as a Research Method From these philosophical origins, methods of investigation began to emerge. Spiegelberg (1995) described â€Å"doing phenomenology† in a philosophical sense, while Giorgi, Van Kaam, and Colaizzi developed research methods which were inspired by phenomenological philosophy but not bound by it (Omery, 2003). Phenomenological research is evolving and expanding since it is now being used by many disciplines. There is debate about how purely one should follow the method and whether it is appropriate to draw from other related methods such as ethnography and grounded theory. Phenomenology as a philosophy is so diverse that purity is probably nonexistent. Because of this it would be difficult to derive a pure research method. Phenomenology as it is Used in this Study The primary influences in developing the methodology for this study were Collaizzi (1998) and Merleau Ponty (2002). Both Collaizzi and Merleau Ponty were chosen because of their specific discussion of bodily functions and their desire to maintain the integration and complexity of these functions. They both believed that perception of reality was in fact reality and that this reality can be described. Careful interpretation can clarify this reality. In the process of interpretation, data are not created, but they are analysed with an attempt to discover their essence. In order to address the research questions posed above, selected individuals will be asked to discuss their experience of holistic healing and the mechanism of their health creation process. Asking people directly seemed an effective way to study meaning, experience, beliefs, expectations, and perceptions of holistic healing. Benner (2002) pointed out that physiological aspects of healing can be studied readily with traditional quantitative research. Much of the research available on psychological, interpersonal, and personality dimensions of health has also been done using quantitative methods. There is a current interest in exploring holistic healing using qualitative means, but no qualitative studies have explored healing. As healing is a lived experience it seems appropriate to use a qualitative method to ask individuals who are in the process of healing to attempt to articulate what they believe is happening.

Impact Of Ocean Acidification On Marine Life Environmental Sciences Essay

Impact Of Ocean Acidification On Marine Life Environmental Sciences Essay One of the main issues with ocean acidification is the impact that it will have on marine organisms over the coming years, and whether or not they are able to adapt to the more acidic waters? The impact upon some marine species may become more of a problem if they play an important role in the food chain, and therefore may eventually affect humans as fish are the main food source for some communities around the world. Research into ocean acidification has found that certain organisms experience reduced calcification or enhanced dissolution when they are exposed to elevated CO2. Many organisms rely on the oceans current pH in order to survive. The major benthic calcifying organisms on coral reefs are the corals, calcifying macroalgae, benthic foraminifera, molluscs, and echinoderms. Corals typically live in compact colonies of many identical individual polyps. Part of this group includes the reef builders, these are important because as the name suggests, they build the reefs. They secrete calcium carbonate to form a hard skeleton and these skeletons can be used as bio-implants for human surgery. A coral reef is a community of many species, such as the corals, plants, invertebrates, fishes, and some other vertebrate animals, such as turtles. The lowering of the oceans pH reduces the ability of coral to produce calcium carbonate and with the conditions expected ocean acidification will compromise carbonate accretion. (Website, 2009) This causes corals to become increasingly rare on reef systems. A large number of species make up tropical coral reefs; however coral communities in cold waters are only made up of one or two species yet provide shelter for many other marine species. (Website, 2009) With ocean acidification reducing the number of coral and as many marine species use the coral as their home and for shelter, the coral reef communities would also be affected and become less diverse and carbonate reef structures will fail to be maintained. (Hoegh-Guldberg, O. et al, 2007) Coccolithophores are single-celled algae, protists and phytoplankton and are found in large numbers throughout the surface euphotic zone of the ocean and ocean acidification seems to have the opposite effect on them compared with other calcifying organsims. (Website, 2010) Coccolithophores are major calcium carbonate (CaCOà ¢Ã¢â‚¬Å¡Ã†â€™) producers in the worlds oceans today accounting for about a third of the total marine CaCO3 production. Whereas ocean acidification reduces the calcium carbonate production in many organisms, studies have shown that it actually causes coccolithophores to increase their CaCO3 production. (website, 2005) Coccolithophores are distinguished by calcium carbonate plates which have an uncertain function and are called coccoliths calcareous nanoplankton, and these are important microfossils. (website, 2011) When coccolithophores make these plates they release carbon dioxide. Whereas some believe that because of this coccolithophores will actually contribut e to the rise in COà ¢Ã¢â‚¬Å¡Ã¢â‚¬Å¡, it is actually unclear of what affect the increase in CaCO3 production will have. This is because these organisms use CO2 during photosynthesis. It is the balance between calcification which produces carbon dioxide and the consumption of CO2 by photosynthesis that will determine whether coccolithophores act as a sink (absorbing CO2) or as a source of CO2 to the atmosphere. So the extra CO2 produced may simply be counteracted by the extra photosynthesis. (Website, 2008) An example of how ocean acidification affects certain marine species is the pteropod Limacina helicina. Their shell is made of calcium carbonate; however studies have shown that the shell is developing at a slower rate due to the lowering of pH. It is anticipated that by 2100 the increase of ocean acidification will slow the development of the shell by 30%. (Website, 2009) Aside from calcification, other organisms may suffer from other adverse effects. Such as physiological or reproductive effects or they may be affected by the negative impacts on food resources. An example of a species that is directly affected by ocean acidification on the lugworm Arenicola marina. There is a simple experiment that can be carried out to show how pH affects the lugworm reproduction simply by keeping the lugworms in seawater of different pHs; some at the current seawater pH, 8.2, some at a pH of 7.8 and some at 6.5. The results show (fig. 1) that as the pH lowers the reproduction of the lugworm is affected. The lower the pH gets the less successful fertilization is. If as predicted by 2100 and the pH of the seawater has lowered to 7.8 then the lugworms may struggle to adapt and therefore may decline in number. Brittle stars (Ophiothrix fragilis) may also see a change in their reproduction as they produce fewer larvae, because they are using more energy maintaining their skeletons in more acidic seas. This has a knock on affect as the brittle star larvae are a key food source for herring. It is clear that ocean acidification in time will have an impact on food chains causing problems for many other organisms that are not at first affected by ocean acidification. It is also possible that tiny algae such as Calcidiscus leptoporus will be unable to survive. These very important algae have been declining by 1% each year; some believe ocean acidification could be the cause as the acidity may make certain nutrients that the algae need less available or that it might even promote the growth of bacteria which damages the natural plankton growth cycle. Ocean acidification also affects the navigation and communication of whales and dolphins. This is because the seas are becoming noisier. As the acidi ty increases, sound travels further. Navigation is important to whales and dolphins as they use it for migration, which is important as they migrate to colder waters to feed and to warmer waters to give birth. It is not just the organisms that live in the oceans that are being affected. Marine mammals such as; polar bears, sea lions, seals, and walruses and also seabirds would see a knock on affect due to ocean acidification and the other impacts of climate change. The main issue is the effect ocean acidification has on the food chain because if one organism that is a main part of the food chain declines then the problem continues up the food chain. So if numbers of fish decline from a lack of food, then the birds that feed on the fish could also decline. However unlike many organisms affected by climate change, it has been discovered that seabirds can actually adapt to the changing environments. So the lower availability of their preferred prey may not be a problem as the birds seem capable of modifying their diets. (Grà ©millet, D. 2009) Ocean acidification will have a definite impact on marine life, as many organisms will be affected. The main issue that can be seen is the impact ocean acidification will have on the food chain, as primary producers may decline then so will the organisms that prey on them and so on as the trend continues up the food chain until it reaches the consumer. If ocean acidification continues at its current rate, by 2100 we could see a vast different in ocean ecosystems. Many species may decline as a direct result of ocean acidification, such as the coral reefs due to reduced calcification. The coral reefs form some of the most diverse ecosystems on earth; therefore many other organisms would be indirectly affected by ocean acidification with the decline of corals. The coral reefs also play an important role for fisheries and fishing communities in poorer countries, a decline of the coral reefs would see a decline in a much needed food source for many humans.

Brother Stories from the Holy Bible Essay -- Cain and Abel Jacob and E

When I was younger my brothers and I would fight over the attention and gratitude of my parents. From reading the Stories of brothers in the Bible I have discovered that brothers have been fighting ever since the beginning of time. Through the stories of Cain and Abel, and Jacob and Esau I have determined that Brothers stories are one of childhood ignorance and desire to obtain everything. Once adolescence has turned to adulthood, brothers seem to reform there ways toward each other due to the realization that you don’t need to have everything to obtain happiness. In book 4 of the Bible the first brother story takes place. It is one of deceit and competition over receiving better blessings from God. This is the story of Cain and Abel. Cain, being the older brother, felt that God was...

Cardio Lab Report Essay Example

Cardio Lab Report Essay Example Cardio Lab Report Paper Cardio Lab Report Paper The smaller blood vessel radius, the lesson blood or fluid flow. 2. Explain the effect that the flow tube radius change had on flow rate. How well did the results compare with your prediction? Flow tube radius change has a direct effect on flow rate. As evidenced in this lab, when flow tube radius was increased, the flow rate was also increased. They are directly proportional. As evidenced trot the text, when flow tube radius increases in a blood vessel, the flow rate is much more free flowing and flows a lot quicker as the radius is increased. When starting with 1. Mm of radius, the flow was very slow, yet when increased to mm, mm, and eventually to Sum, he flow within the blood vessel incrementally increased. 3. Describe the effect that radius changes have on the laminar flow of a fluid. Laminar Flow is defined as the free-flowing blood in the middle of the vessel. Radius change is directly proportional on laminar flow. In a constricted vessel, proportionately more blood is in cont act with the vessel wall and there is less laminar flow, significantly diminishing the rate Of blood flow in the vessel, yet if the vessel is more dilated, or the radius is increased. Ore blood flow is able to get in, thus increasing the blood flow. The bigger the radius, the more laminar flow of fluid. 4. Why do you think the plot was not linear? (Hint: look at the relationship of the variables in the equation). How well did the results compare with your prediction? If the variables are radius on the X-axis and flow rate on the Y-axis, the experiment called tort the experimenter to incrementally increase the radius and plot the results, As we know, radius is directly proportional to flow rate in that as the radius increases so does the flow rate, therefore, the plotted graph has to be linear. If one increases, 50 does the other going in a straight line! Activity 2 Questions: I. Describe the components in the blood that affect viscosity? The components in the blood that affect viscosity are the presences Of plasma proteins and formed elements such as white blood cells (leukocytes), red blood cells (erythrocytes), and platelets. When these formed elements and plasma proteins in the blood slide past one another, there is an increase in the resistance to flow. 2. Explain the effect that the viscosity change had on flow rate. How well did the results compare with your prediction? Viscosity is defined as the thickness or stickiness of a fluid. In regards to flow ate, they are inversely comparable and thus as you increase viscosity or the thickness of the blood, the flow rate decreases, As seen in the graph, increasing the viscosity inversely decreases the flow rate each time you increased by 1. 3. Describe the graph of flow versus viscosity. As evidenced in the graph, the constants in this experiment ever radius, length, and pressure. The reburials were flow rate and They axis represented flow rate and the x axis represented viscosity. As viscosity increased, the flow rate decreased causing a linear or inverse curve relationship going down. 4. Discuss the effect that polytheism would have on viscosity and on blood flow. Polytheism is a condition in which excess red blood cells are present. We learned earlier that an increase in red blood cells results in an increase in blood viscosity. An increase in blood viscosity directly affects blood flow, in that blood flow would decrease. Thus, the presence of polytheism would inversely affect blood flow rate by decreasing it. Activity 3 Questions: l. Which is more likely to occur, a change in blood vessel radius or a change in blood vessel length? A change in blood vessel radius is more like to occur because blood vessel length only increases as we grow. into maturity and in adulthood blood vessel lengths stay constant. The only possibility of blood vessel length changing is when we gain or lose weight. Through the process of visitation, or the smoothing of the blood vessel muscle, you can change the radius of the vessel more frequently. 2. Explain the effect that the change in blood vessel length had on flow rate, How well did the results compare with your prediction? Blood vessel length, when increased causes more friction or resistance thus making it more difficult for blood to flow through the vessel. In summation, increasing blood vessel length inversely effects flow rate but decreasing flow rate. My prediction was that an increase in blood vessel length would inversely effect blood flow. As evidenced in this experiment, with the increase of the blood vessel length, there was a decrease in blood flow. 3. Explain why you think blood vessel radius can have a larger effect on the body that changes in blood vessel length. In the blood flow equation (as seen to the right), blood flow is directly proportional to the fourth power of vessel radius. Dramatic changes happen n regards to blood flow because of small changes in blood vessel radius. The smaller the blood vessel radius, the greater the resistance. Blood vessel radius is the single most important factor in determining blood flow resistance, 4. Describe the effect that obesity would have on blood flow and why, As referenced from this experiment, weight, either gain or loss effects blood vessel length. A change in blood vessel length can only be altered through the gain or loss of weight. As evidenced in this experiment, when blood vessel length is increased as result of weight gain, there is greater resistance or ruction Within the vessel making blood flow through that vessel more difficult thus decreasing blood flow. Obesity different effect blood flow in that, there are increased blood vessel lengths, causing greater friction or resistance Within the vessel and a decrease in blood flow. Activity 4 Questions: 1. Explain the effect that pressure changes had on flow rate. How well did the results compare with your prediction. Pressure changes have a profound effect on flow rate. As pressure increases, flow rate also increases. They are directly proportional, In regards to my prediction, I redirected that as pressure increased, so would flow rate. 2. How does the plot differ from the plots for tube radius, viscosity, and tube length? How well did the results compare with your prediction. The plot for pressure in linear in that, an increase in pressure is directly proportional to flow rate. It was a perfectly straight line upwards as pressure increased. In regards to the plot for tube radius, it was very similar in that results were more curve shaped but went in the same directly upward. As vessel radius increased so did flow rate. In regards to viscosity, they ever drastically efferent, as viscosity increased, the rate of flow decreased because there Vass more resistance. In regards to tube length, this is drastically different than pressure because with an increase in tube length, there is a decrease in rate Of flow because there is more resistance within the vessel itself. After learning that vessel radius is the greatest factor in regards to rate, predicted that With an increase in pressure there would also be an increase in flow rate. 3. Explain why pressure changes are not the best way to control blood flow. Pressure changes are not the best way to control blood flow because it could lace more stress on the heart (which causes the initial pressure) and requires the heart to change its force of contraction. The blood vessels need time to respond to that change in force as well as the large arteries around the heart. T required for them to have more tissue in their tunics to accommodate the heart and its increase of force. Plus, the best way to control blood flow, as seen trot these experiments is through increasing vessel radius. 4. Use you data to calculate the increase in flow rate in ml/min/mm In this experiment, radius, viscosity, and length remained constant, and pressure ND flow rate were the variables. I started off with a pressure of 25 mm Hu g and the flow rate was sum/min_ As I increase the pressure by AS mm Hug each time, the flow rate increased by about 35 mm/min each time. Activity 5 Questions: 1. Explain the effect of increasing the right flow tube radius on the flow rate, resistance, and pump rate. Increasing the right flow tube radius is directly proportional to increasing flow rate. As evidenced in other experiments, increasing tube radius decreases resistance thus increasing flow rate. In addition, as the right flow tube radius increased, so did the pump rate. Each time that increased the right flow tube radius by . Mm, the pump rate increased as did the flow rate because of the decrease in resistance. 2. Describe what the left and right beakers in the experiment correspond to in the human heart. The left beaker represents the side of the heart where blood is pumped through the lungs to the opposite side of the heart. The right beaker represents the side of the heart that delivers blood to the system of the body. 3. Briefly describe how the human heart could compensate for flow rate changes to maintain blood pressure The human heart compensates for flow ate changes by altering heart rate, stroke volume or resistance. If resistance decreases, heart rate can increase to maintain the pressure difference. If resistance is decreasing, there is an increase in flow rate. Activity 6 Questions: 1. Describe the Frank-starling law in the heart. The Frank-starling law in the heart refers to when more than the normal volume of blood is returned to the heart by the venous system. In this process, the heart is stretched which results in a more forceful contraction of the ventricles, This causes more than normal amounts of blood to be ejected by the heart which raises stroke volume. 2. Explain what happened to the pump rate when you increased the stroke volume. Why do you think this occurred? How well did the results compare with your prediction? When you increase the stroke volume, there is an inverse decrease in pump rate, even though there is a constant amount of flow that results. This is directly the opposite of my predictions, yet learned that the reason why pump rate decreases when stroke volume increases is because the heart intrinsically alters stroke volume to accommodate changes in preloaded or during the period where the ventricles are stretched by the end diastolic volume. Stroke volume is also enthroned by the strength and force Of contractile Of the heart. 3. Describe how the heart alters stroke volume? The heart alters stroke volume by altering the pump volume or the contractile. By altering the contractile. You are altering the strength of the cardiac muscle contraction and its ability to generate force. 4. Describe the intrinsic factors that control stroke volume. The intrinsic factors that control stroke volume are heart rate and cardiac output. Total blood flow is proportional to cardiac output. Thus, when the stroke volume decreases, the heart rate music increase to maintain cardiac output. Yet, when stroke volume increases, the heart rate must decrease to maintain cardiac output. Activity 7 Questions: 1. Explain how the heart could compensate for changes in peripheral resistance. The heart can compensate for changes in peripheral resistance by decreasing blood viscosity and through adjusting the force of contraction of the heart. Increasing contractile or forcing contraction of the heart combats afterworld and blood flow resistance. Increasing contractile will increase cardiac output by increasing stroke volume. 2. Which mechanism had the greatest compensatory effect? HOW well did the My prediction was that increasing the left flow tube radius would have the greatest impact in regards to blood flow into the right tube, but adjusting the force of contraction of the heart had the greatest compensatory effect on the flow of blood into the right beaker. . Explain what happened when the pump pressure and the beaker pressure were the same. How well did the results compare with your prediction? When the pun pressure and the beaker pressure were the same, the valve would not open because there was insufficient driving pressure to force fluid out of the pump. This was adverse to my prediction, where predicted that there loud be an increase of flow, but was incorrect, in that nothing happened and there was no flow. 4. Explain feather it valued be better to adjust heart rate or blood vessel diameter to achieve blood flow changes at a local level. Think that it would be better to adjust heart rate in order to achieve blood flow changes at a local level. Although the text and experiments hue demonstrated that it is more effective to increase blood vessel diameter in order to increase the rate Of flow Within blood vessels, I think that exercise increases your heart rate which is directly linked to an increase in blood flow.
