Curriculum Development Paper - Essay Example Health workers need to be at the fore front in promoting healthy living which simply begins by simple responsibilities like washing hands. Hands should be washed at minimum; before food preparation, during and after cooking; before eating; before and after handling patients; after using the washrooms and after sneezing, coughing and blowing noses, Hand washing Liaison Group (1999). To wash hands is the best strategy to prevent the spread of germs in the healthcare environment. The hospitals are full of germs (disease causing micro organisms) and nurses have some power of ensuring that their spread is prevented. In order to impact this knowledge to the nurses, a lesson plan will be designed to guide the process of refreshing the knowledge on why washing hands is extremely significant in the healthcare environment, Hand washing Liaison Group (1999) About 20 nurses washing their hands will spend only five minutes when this is done at fifteen seconds each and if this is done throughout the day, a lot of time will be spent but it would be worth it as germs will be reduced considerably and the spread will also be limited. The nurses will have to wash their hands in warm water by using the hospital soap dispenser and leally lather it up. The nurses will wash the front as well as the back of their hands and they will pretend that they are going to handle a very delicate situation like surgery. The soap should be massaged between the fingers ensuring that the nails are properly washed and this should take about fifteen seconds per individual. The nurses can be timed (Bergquist & Pogosian 2000). The scrubbing action is very important as it helps to break up germs and remove them altogether. After this, hands should be properly rinsed with clean water and dried with a clean piece of cloth preferably clean white towel or the fresh paper towels currently in use. Nurses should note that when cleaning hands in the washrooms used by many people, the paper towel is the

Is Democracy a Better form of Government Essay Example for Free

Is Democracy a Better form of Government Essay Democracy is the best form of government simply because no other form of government is known to work well. Democracy may have its flaws but all in all it works very fluidly. Socialism, for example, does not even come close to the best form of government. One can easily see this in Greeces current state. Democracy has never led to complete government disorder like one can see Socialism does. Democracy allows us the freedom to choose. The majority of our country is allowed to choose what they feel is best for them. It is not just one person deciding what they think is best for everyone else. Democracy will always win out over other forms of government. This process can happen through voting. Right to vote is a human right of every citizen. Political Rights form a distinct category of Human Rights. Right to vote, right to contest at elections and the right to hold public office are considered important political rights. A democracy seems to be the most stable form of government yet. No one person has power. No one ideology is deemed better than another. In a democracy, if something doesnt work, it can and should be changed by the populace. Theocracies, monarchies and socialism all have their downsides. Democracy isnt perfect, but that form of government seems to be the most peaceful, especially in America. â€Å"What difference does it make to the dead, the orphans and the homeless, whether the mad destruction is wrought under the name of totalitarianism or in the holy name of liberty or democracy? † ? Mahatma Gandhi Peoples democracy is the lifeblood of socialism. As an important part of the overall reform, political restructuring must be constantly deepened along with economic and social development to adapt to the growing enthusiasm of the people for participation in political affairs.

Health Impact Assessment for Policy-Making

Health Impact Assessment for Policy-Making 1. Introduction Indeed, a lot of changes happened particularly on how the people deal on health issues. In the past, medical concerns are not the main concern of the society. However, in the 21st century, due to some factors that affect the health of individuals, diseases, such as diabetes and hypertension are the major problems of the population. Because of these, responsibility for health plays a major role in national and international healthcare policy. The government implemented some strategies to address the health concerns of the society. For instance, the governing bodies increased the healthcare budget because of the mushrooming health problems. However, some people argue that prevention is better than cure and they contest that the government must spend more of their financial budget on activities that promote health and prevent illness. Effective preventive healthcare plays an important part in preventing disease and gives the people the best chance for a healthier life (Australian National Preventive Health Agency,2013). It also helps to improve the performance of our public health service. Thus, greater attention should be paid to strategies of promoting health. Health promotion goes beyond health care. It puts health on the agenda of policy makers in all sectors and at all levels, directing them to be aware of the health consequences of their decisions and to accept their responsibilities for health. The responsibility for ensuring the right to health for all lies not only with states and their obligations to their own people, but also with the international community. The case study depicts the responsibility for health in different aspects and it appraises the contemporary issues in healthcare and their impact on national and international healthcare policy. In addition, it also emphasizes the justifications for policy intervention solutions on contemporary issues in the international context. This report may help the individuals and the society on how to face healthcare issues. It will be a great success for the nation if healthcare issues will be addressed. 2. Evaluate the impact the contemporary issue discussed in your case study would have on national and international healthcare policy. As discussed in the case study, the major source of health problem comes from unhealthy lifestyle of individuals such as smoking, sedentary lifestyle and poor eating habits. How can the society decrease or eliminate these problems? The governing bodies implemented some strategies in order to combat the health concerns of the society. They plan to improve some policies, both in national and international context. For instance, they give emphasis on strategies of health promotion because the costs for preventive programs are much cheaper than activities that help treating the actual health problems. States hold the primary responsibility to fund and ensure all the essential goods and services under the right to health (World Health Organization, 2014). This may include investing enough resources on health promotion. Health promotion strategies include mass campaigns and people awareness programmes. These activities more often than not can be seen in the school or community where the educators impart the significance of maintaining good health. Through health promotion, the people may realize the importance of having a healthy lifestyle and achieve the optimum health and well-being. As a result, the public can be more active by exercising regularly and playing some sports. Furthermore, they can practice good eating habits and stop smoking to prevent illness. Truly, responsibility for health should be a collaborative effort among individuals and the societies in which they live. As an effect, both can benefit from one another. One good example is the government assistance for the public on how to avoid diseases. Both of them can benefit if the people abide the rules by the law makers. If practiced by the populace, the government can save the resources that were not used for medical treatment for instance. The extra funds then can be directed to other projects which can give additional benefits to the people in general. The effects of medical concerns should be carefully considered by the people, especially the policy makers, so they can amend some policies to effectively improve the health status of the public. In the case study, the health problems would have a great impact on international and national healthcare policy. Existing poor health condition may serve as an eye-opener to the community. Because of the untoward effects of unhealthy way of living such as , they take precautions and some steps to practice a healthy lifestyle in order to alleviate them. National and international healthcare policy can be upgraded using the ideas that can be harnessed to this case study. They may execute effective strategies to promote health and prevent from getting sick. For example, unhealthy habits such as cigarette smoking, excessive use of alcohol and other harmful substances should be restricted or banned in the community by implementing strict laws. Although there are existing policy to address these problems, the policy maker may improvise the law. Punishments and fines may be given to individuals who violate the law. For instance, individuals who are caught smoking in non-smoking area will be jailed for a day and they are required to attend a community service for 1 week. On the whole, national and global health governance is essential because states will not accept national and international norms without genuine partnerships, equitable burden sharing and efficient programmes that improve health outcomes. Yet, political, legal and economic challenges impede effective governance. Countries face serious problems of fragmentation, duplication, and even confusion, among the deluge of global health actors and initiatives. Health ministries often lack basic knowledge of, and control over, foreign-supported programmes. The public needs a system of governance that fosters effective collaborative effort and coordinates initiatives to create synergies and avoid destructive competition. 3. Discuss and critically analyse the rationale or justifications for putting into place each of the below listed types of policy intervention solutions globally to address the contemporary health issue highlighted in your chosen case study: 3.1. Education and training As defined by many resources, education is an essential human virtue. Man becomes man through education. He is what education makes him. It has been rightly said that without education, a person is a splendid slave, reasoning savage. Education is necessary for society. Education fashions and models man for society. Man cannot be conceived merely in terms of his biological existence. Education brings into focus the social aspect of man. Education signifies mans supreme position in society. Education is an essential basis of good life. A man becomes a human being in the real sense when he is transformed from primarily an animal being into a human being. In short, education is an essential concomitant of all human societies. Through education, the people can acquire knowledge and wisdom about everything in life. The people can solve problems successfully because they can apply the knowledge they have gained in order to solve their concerns. Meanwhile, training, is the process by which s omeone is taught the skills that are needed for an art, profession, or job. Training is beneficial for the new staff particularly because it makes them proficient and more competent in their area of work. Developing competence has become a crucial issue for establishing a smart workforce that can achieve a competitive success. A major factor or function of Human Resource Management that differentiates it from personnel management is training and development. Training can be defined as a planned process by which people acquire the capabilities and competencies to aid in the overall achievement of the organisations goals and objectives. Training can be seen from the very entrance into the organisation, for example, orientation where the employee is taught the organisations culture. It continues into the probation period, where employees gain sufficient skills for the position held and can also be seen throughout the duration of employment. Thus, training act as a remedy to change with in an organisation. There is a strong link between training and learning, both foster a permanent change in behaviour according to the behaviourist approach and thereby lead the movement toward a learning organisation.. Both education and training are essential in order to address the contemporary issue stressed in the case study. By educating the public, the people can become aware of what is happening around them. Furthermore, they can improve their way of living because of the wisdom and knowledge they have as part of the learning process. Through education, they can help promote health and prevent diseases. Stressing out the importance of preventing illness, for instance, can help the individuals achieve a quality of life. By making them aware of the cons of unhealthy habits, they can avoid being sick. For example, the person who is aware that eating foods high in cholesterol can make the person at risk for stroke or any cardiovascular diseases may stop taking such unhealthy foods. Training, on the other hand, is helpful to an individual in carrying out successfully a task. One example is by providing training to healthcare workers. Resources should be provided to maintain a high quality of trai ning. Training can be hard if it is poorly funded because they usually require aids in order to demonstrate procedures. Another good example is in a healthcare community center, where a program can be conducted once a month. Before the healthcare workers perform their task, they are trained on how to deal the people with different personalities and how to deal the community as a whole. They give health teachings such as obesity. As mentioned in the case study, obesity is one the leading cause of forming other debilitating diseases, such as diabetes, cardiac diseases, and hypertension and thus, obesity should be avoided. By imparting information, like proper diet and exercise, this health problem can be prevented. 3.2.Tax benefits and payments to caregivers Tax benefit rule is a judicially created doctrine seeking to repair some of the inflexibility inherent in the annual accounting system. According to this rule, if any loss or expense deducted in the previous year is recovered by the tax payer, the recovery must be included in the current years gross income to the extent that it was previously deducted. The tax benefit rule ensures that if a taxpayer takes a deduction attributable to a specific event, and the amount is recovered in a subsequent year, income tax consequences of the later event depend in some degree on the prior related tax treatment. Tax benefits are indeed a great help to individuals who needs healthcare assistance. Nowadays, with the rising cost of medical supplies and procedures, tax benefits that will reduce the cost of health care expenses for example, is a great help especially to those people who are in dire need of financial assistance. From the tax, the government can successfully implement and carry out projects that can contribute to individual’s welfare. They may effectively plan and perform heath preventive programs because of the individual’s tax contribution and collaboration of the people. Meanwhile, payments to caregivers are important. Since the healthcare workers are the front liners in providing care for the people who need assistance, they should be given sufficient incomes. Giving them a salary which help them survive from day to day living and help them save for their future use help them provide a quality care for people who needs their help. Instead of working double shifts to earn more money for their needs, they may only work a single shift. Their extra time can be allotted for their family and for themselves to rest. Because of this, they can be relieved from stress and enjoy their day offs. This can yield a good result because a well-rested individual can give and provide a quality care for their patients. 3.3. Respite care As defined by the Ministry of Health (2014), respite service should provide a safe, enjoyable environment with staff able to support the disabled person to participate in their community. Respite care is generally short-term and intermittent, available in community settings and in rest homes, and part of the support network available to a person and their carers. This is very important since individuals who provide care experience stress. This may be in the form of emotional, financial or physical burden. With stress, an individual who provides care can cause negligence or abuse to the patient. To avoid this, they should also have a break or a day off. During their break or day off, somebody would temporarily relieve them of their duty. This is a great help to the care givers, since they can reduce or eliminate the stress that builds inside them. And with this, as they return to duty fully recharged, they can provide and maintain a quality care for their patients. 3.4. Business regulations combining work and care giving Each year, there are increasing number of people who needs assistance and care to maintain their well-being. Because of this plight, the demand for care givers is also escalating. Thus, a lot of health care centers are being made, either public or private, to accommodate the increasing number of individuals who need assistance. Nowadays, rest homes are common in some countries and there should be regulations that must be maintained in order to provide a quality care and assistance for the patients. A good example is, providing the right number of staff to the number patients available in the care homes. There should be enough staff to attend the needs of the patients in order to render a good quality care, like assisting a disabled person to transfer to a chair. Big patients need two or more staff to accomplish the task such as showering them and doing cares in order to avoid injuries to patients and also to caregivers. For health and social care staff to work together, they must be able to share information about a person’s assessments, treatment and care. One of the most important legal right one have as a caregiver is about his employment. The unpredictable nature of caregiving, and the time that it takes to provide care, often make it difficult to continue working on a normal schedule. In fact, the Department of Labor’s latest investigation found that employee complaints with respect to balancing career and family often occur because an employer refuses to reinstate an employee after an extended leave. Generally, these complaints can be resolved fairly easily, although to date, 16 legal actions have been taken against employers for violations of the Family and Medical Leave Act (FMLA). All in all, in order to attend the needs of the patient, business regulations should be fair and just to the employees and consumers. 4. Conclusion This paper makes the claim that a key activity required to promote healthy policy-making at the local level is health impact assessment. Highly participatory local health impact assessment can be used to identify negative health impacts that call for policy responses, and to identify and encourage practices and policies that promote health. Socially responsible decision-making for improved equity-in-health is stimulated by community-level health impact assessment because it is a practical tool to help communities come to grips with local conditions that need changing if better health for all is to be realized. Even with the advancement of knowledge on medicines, society still faces the burden on health related issues. Health issues should be attended immediately due to the fact that not only the individual who suffers the sting of the disease but there love ones are also affected. Health prevention strategies should be promoted and initiated in every community. Aside from the fact th at it is more cost-effective than curing the actual diseases, it can also benefit the public by practicing healthy lifestyle. Health promotion is indeed significant in order to achieve the optimum of health and well-being. Health issues can affect everyone, it can cause physical, emotional and financial burden. It is a miserable situation in which everyone involved to the individual especially the family members is being pulled in. Health issues then affects the economy of a nation. And if not properly attended, it may cripple the nation’s wealth. In addition, through collaborative effort of the individual and society, the health issues can be minimized or avoided through effective implementation of health promotion strategies, community projects and programmes by the government, community and the individuals.

Shape Memory Alloys Research

Shape Memory Alloys Research 1.1 General considerations When a regular metallic alloy is subjected to an external force greater than its elastic limit, it deforms plastically, i.e. the deformation persists after returning to the unloaded state. The Shape Memory Alloys (SMAs) do not follow this behavior. At low temperatures, an SMA specimen may undergo a plastic deformation of about few percent, and then fully recover its initial shape that had at higher temperature by simple heating above a threshold temperature. Their ability to recover their form when the temperature is raised, makes this class of materials unique. This phenomenon has been discovered in 1938 by researchers working on the gold-cadmium alloys [Gilbertson (1994)]. The shape memory effect remained a laboratory curiosity until 1963, when the first industrial and medical applications appeared. 1.2 Martensitic Transformation The shape memory effect is based on the existence of a reversible phase transformation of thermoelastic martensitic type [Kurdjumov, Khandros (1949), Kumar, Lagoudas (2008)], between a microstructural state at high temperature (austenite phase) and a microstructural state at low temperature (martensite phase) [Patoor et al. (2006), Lagoudas et al. (2006)]. Austenite has in general a cubic crystal lattice, while martensite is of tetragonal, monoclinic, or orthorhombic crystal lattice. The transformation from one crystal lattice to the other occurs by distortion of the shear lattice does and not by atoms diffusion. This type of transformation is called martensitic transformation [Perkins (1975), Funakubo (1987), Otsuka, Wayman (1999)]. In reality, the matrenitic transformation in SMAs is a phase transformation of the first order, where there is co-existence of several phases, and there is presence of interfaces between the phases [Guà ©nin (1986)]. Historically, the term martensitic transformation describes the transformation of the austenite of steels (iron-carbon alloys) to martensite during a quenching. By extension, this term has been generalized to a large number of alloys whose phase transformations have certain characteristics typical of the transformation of steels [Rosa (2013)]. During martensitic transformation of a SMA, the crystal lattice of the material changes its shape. The microstructure of martensite is characterized by a change in shape and by the difference in volume, which exists between matrensitic and austenitic phase [Duerig et al. (1990)]. Therefore, internal strains arise during the emergence of martensitic areas within the austenite. The internal strains can be partially relaxed by the formation of several areas of self-accommodated martensite crystals that minimize the overall deformation induced. These areas called variants and are oriented in different crystallographic directions [Kumar (2008)]. In the absence of external strains, these variants are equally possible and the distribution of self-accommodated groups allows the material to be transformed in order to retain its original shape. Therefore, the formation of the martensite results in elastic (reversible) deformations [Funakubo (1987)]. At constant temperature, the martensite-austenite interfaces are in steady state. A change in temperature in one direction or the other results in moving these interfaces to the benefit of one or the other phase structure. The interfaces can also move under the action of an imposed strain. A specimen can therefore be distorted not by sliding, which is the usual mechanism of plastic deformation, but by the appearance and disappearance of martensite variants [Kumar (2008)]. Therefore, during martensitic transformation atoms in the structure move on very small distances leading to deformation of the crystal lattice. This causes a small variation in volume with shearing of the structure in a specific direction. During the transformation process, the growth of martensite crystals occur in form of platelets to minimize the energy at the interface. The martensitic variants can occur in two different types: twinned martensite (formed by combination of self-accommodated martensite variants) and detwinned martensite (reoriented martensite) where a particular variant dominates [Liu, Xie (2007)]. The characteristic behavior of SMAs is based upon the reversible phase transformation from austenitic phase to martensitic phase and the opposite. By cooling under zero loading, the crystal sructure changes from austenitic to martensitic phase (forward transformation to twinned martensitic phase). This transformation is resulting in the development of a number of martensitic variants, which are arranged in a way that the average change in macroscopic shape is insignificant, causing a twinned martensite [Leclercq, Lexcellent (1996)]. When the material is heated at the martensite phase, the crystal structure is transforming to austenite (reverse transformation from detwinned martensitic to austenitic phase), leading to recovery of shape [Sabu ri, Nenno (1981), Shimizu, Otsuka, Perkins (1975)]. The above process is called Shape Memory Effect (SME) [Schetky (1979), Wayman, Harrison (1989)]. The martensitic transformation is characterized by four temperatures (Figure 2) [Gotthard, Lehnert (2001)]: MS: Temperature below which the martensite appears (martensite start) MF: Temperature below which the entire sample is transformed into martensite (martensite finish) AS: Temperature above which the austenite appears (austenite start) AF: Temperature above which the entire sample is transformed into austenite (austenite finish) The transformation begins at the cooling to the temperature MS. This transformation is completed to the temperature MF. Between these two temperatures, there is coexistence of two phases, which is a characteristic of transformation of the first order. If the cooling is interrupted, the material will not change. To go back to the initial shape, the temperature is increases so that the inverse transformation begins at the temperature AS and finishes to temperature AF, which is higher than MS [Massalski et al. (1990)]. If the trace on a diagram (Figure 1) the volume fraction of material processed as a function of temperature, there is a hysteresis loop, due to the presence of an irreversible energy corresponding to dissipation of mechanical energy transformed into heat [Ortin, Planes, Delaey (2006), Wei,Yang (1988)]. Figure 1 Martensitic transformation temperatures [Gotthard, Lehnert (2001)] The thermoelastic reversibility of the crystal lattice is certain in the case of an ordered alloy [Otsuka, Shimizu (1977)]. The correlation between the manifestation of martensitic transformation and atomic order was shown experimentally in Fe-Pt SMAs [Dunne, Wayman (1973)]. Nevertheless, in disordered alloys, such as Fe-Pd, Mn-Cu and In-TI, can occur thermoelastic transformation too. The atomic order is, therefore, a sufficient condition for manifestation of thermoelastic transformation, but not necessary [Otsuka, Shimizu (1977)]. 1.3 Thermomechanical properties of SMAs Several effects specific to the SMAs appear through the transformations of the crystal lattice as a function of temperature and of the field of stresses applied on the material [Duerig, Melton, Stà ¶ckel (2013)]. 1.3.1 Pseudoelastic Effect In general, by pseudoelasticity we describe both the materials superelastic behavior, as well as rubble-like behavior. Superelastic behavior is called the reversible phase transformation produced by thermo-mechanical loading. Rubber-like effect refers to the reversible martensitic re-orientation. The stress-strain curve during this process resamples to the superelastic behavior, which is similar to rubbers nonlinear elastic behavior [Otsuka, Wayman (1999)]. Therefore, a part from inducing phase transformation thermally, martensitic transformation can also be prompt by applying on the material appropriately high mechanical loading, resulting in creating a martensitic phase from austenite. When the temperature of the SMA goes above AF, shape recovery is resulted while unloading. Such behavior of the material is termed pseudoelastic effect [Kumar (2008)]. Stress-induced martensite, is generally forming from austenite when external stress is present. The process of forming stress-induced martensite can occur through different thermomechanical loading routes [Miyazaki, Otsuka (1986)]. One form of stress-induced martensite is the detwinned martensitic phase formed from austenitic after application of external stress. The material, during the stress-induced martensitic transformation and the reversed process, shows nonlinear elastic behavior described by closed à Ã†â€™-ÃŽÂ µ curves. This nonlinear elastic behavior is called pseudoelastic transformation [Otsuka, K. and K. Shimizu (1981)]. The shape recovery is due to crystallographic reversibility of transformation, like in the shape memory effect. Hence, the two phenomena, transformation pseudoelasticity and shape memory effect are practically the same except the fact that reverse transformation is produced by warming the specimen to temperature above AF. In reality, an alloy that un dergoes thermoelastic martensitic transformation exhibits both transformation pseudoelasticity and shape memory effect [Otsuka, K. and K. Shimizu (1981)]. Nevertheless, for occurring transformation pseudoelasticity, the necessary stress for slip should be greater than that for stress-induced martensite transformation. As an example, we can refer to equiatomic Ti-Ni alloys which are exposed to slip and do not exhibit any transformation pseudoelasticity, regardless of their Ni content. It was shown, however, that Ni-rich Ti-Ni alloys subjected to annealing after cold working, causing refining of their grain size, leads in raising critical slip stress, which results in any transformation pseudoelasticity [Miyazaki et al. (1982), Saburi, Tatsumi, Nenno (1982), Saburi, Yoshida, Nenno (1984)]. The existence of transformation pseudoelasticity is affected by crystalline orientation, composition of the alloy, and direction of applied stresses [Miyazaki, Otsuka (1986)]. 1.3.2 One-Way Shape Memory Effect Another property of SMAs is the one-way shape memory effect. It takes place in four steps: (1) The material is cooled to a temperature lower than MF (the parent austenitic phase) to obtain self-accommodated martensite. (2) Re-orientation of variants of the martensite is obtained via application of stress. (3) The stress is released at constant temperature T F. The material remains to a shape depending on the stress field. (4) The sample is heated at a temperature T > AF making re-appear the austenitic phase and the material gets its original shape, as shown in Figure 2. Figure 2 One-way shape memory effect [Miyazaki, Otsuka (1986)] Two conditions are necessary for occurring shape recovery by shape memory effect. Firstly, the transformation should be reversible, and second, slip should not occur during the entire deformation process. Martensitic transformations in ordered alloys are reversible in nature [Miyazaki, Otsuka (1986), Arbuzova, Khandros (1964)], so the entire shape memory effect mainly occurs in this type of alloys. The second condition is necessary because in the case of high stress and every type of deformation mode (stress-induced martensitic transformation in parent phase, twinning in the martensitic phase) slip can be induced, resulting in plastic strain and, not completed recovery of shape. In the one-way shape memory effect, the shape in memory by the SMA is the one of the parent phase. 1.3.3 Two-Way Shape Memory Effect The two-way shape memory effect is the reversible passage of a shape at a high temperature to another shape at low temperature under stress. The two-way shape memory effect should precede the SMA training [Nagasawa, et al. (1974]. Training of SMAs consists of temperature cycling at constant stress or stress cycling at constant temperature. During training, microstructural defects (i.e. dislocations) lead to internal stresses and therefore promote oriented martensite. A SMA subjected to training can then move from austenitic phase to oriented martensite under zero load by simple change of temperature [Schroeder, Wayman (1977)]. It has then a shape in memory for each of the two phases. Various methods that cause two-way shape memory effect have been suggested, such as, large deformation in stress-induced martensite transformation at temperatures > MS [Delaey et al. (1974)], shape memory effect training [Schroeder, Wayman (1977)], stress-induced martensite training [Schroeder, Wayman (1977)], training involving both of shape memory effect as well as stress-induced martensite [Perkins, Sponholz (1984)] remaining in martensite state while heating at a temperature > AF [Takezawa, Shindo, Sato (1976)], as well as using precipitates [Tadaki, Otsuka, Shimizu (1988)]. 1.4 Transformation Induced Plasticity (TRIP) Several experimental studies have shown the development of nonlinear plastic (irreversible) strain when phase transformations occur [Greenwood, Johnson (1965), Abrassart (1972), Magee (1966), Desalos (1981), Olson, Cohen (1986), Denis et al. (1982)]. This mechanism of deformation is termed Transformation Induced Plasticity (TRIP), resulting from internal stress rising from the change in volume related to the transformation, as well as from the associated change in shape [Marketz, Fischer (1994)]. TRIP differs from classical plasticity. Although plasticity is caused from the applied stress or variation in temperature, TRIP is triggered by phase variations, and occurs even at low and constant stress levels [Gautier et al. (1989), Leblond et al. (1989), Gautier (1998), Tanaka, Sato (1985), Fischer et al. (2000, 1996)]. TRIP takes place because of two separate mechanisms. The first, refers to a process of accommodation of micro-plasticity related to volume change [Greenwood, Johnson (196 5)]. The other, refers to an orientation caused by shear internal stresses, favoring the direction of preferred orientation for the formation of martensite when and external stress is present, which involves change in shape [Magee (1966)]. TRIP is caused by the difference in compactness of the lattice structure between the austenite (parent) and the martensite (product) phase [Greenwood, Johnson (1965)]. During martensitic transformation, this difference has produces a change in volume as well as internal stresses causing plasticity in the phase with less yield stress, which is weaker   [Paiva, Savi, Pacheco (2005)].

Hucklebery Finn Literary Figures :: essays research papers

The Adventures of Huck Finn CHARACTER: Character Name  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Description  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Quote Huckleberry Finn  Ã‚  Ã‚  Ã‚  Ã‚  A young outcast boy who is always forced to survive on his own due to lack of authority. He is quick-witted and able to make intelligent decisions, but is often influenced by his friend Tom.  Ã‚  Ã‚  Ã‚  Ã‚   Jim  Ã‚  Ã‚  Ã‚  Ã‚  A black slave that belonged to Miss Watson but escaped after she threatened to sell him. Huck and him went off together on the river looking for the free states.  Ã‚  Ã‚  Ã‚  Ã‚   The king & the duke  Ã‚  Ã‚  Ã‚  Ã‚  Fugitives that joined up with Huck and Jim on the raft. They posed themselves as a king and a duke and performed scandalous plays to rip people’s money off. They were later both tarred and feathered.  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚   DICTION:   Ã‚  Ã‚  Ã‚  Ã‚  The diction used in The Adventures of Huckleberry Finn is mostly informal and neutral. SYMBOLISM:   Ã‚  Ã‚  Ã‚  Ã‚  The Adventures of Huckleberry Finn has many important symbols throughout the novel. One major symbol is the raft that Huck and Jim travel on through a majority of the book. In Chapter 18, Huck states, â€Å"We said there warn’t no home like a raft, after all. Other places do seem so cramped up and smothery, but a raft don’t. You feel mighty free and easy and comfortable on a raft.† Huck said this after he and Jim escaped from the troublesome feud between the Grangerfords and the Sheperdsons. The raft represents to Huck an escape from the troublesome and sick society in the outside world. The raft also represents live itself as it floats along the river.   Ã‚  Ã‚  Ã‚  Ã‚  Along with the raft, the river represents the path of life and how it can turn in many unexpected ways and how obstacles can get in the way of things at any time. During Huck and Jim’s journey along the Mississippi, obstacles in the form of troublesome slave hunters and scandalous royalty constantly took them off course and led them on a temporary sidetrack. Once they are able to overcome the obstacles or outrun trouble, Huck and Jim were back on the river enjoying life. Like the river, life also has many obstacles that must be overcome before one can continue down the path. THEME:   Ã‚  Ã‚  Ã‚  Ã‚  The Adventures of Huckleberry Finn is a novel about trusting what one believes and knows is morally right. When the king and the duke sell Jim, Huck writes a letter to the Widow telling her about the whereabouts of Jim. Before he sends it though, he tears it up because he realizes how close of friend Jim has become.

Conflict in a Dangerous Spring :: essays research papers

In the novel Dangerous Spring, by Margot Benary-Isbert, conflict is a reoccurring theme between many characters and events that provides the driving force for actions in the story. The story takes place during the final days of World War II. Although this point in time provides the basis for the conflict, there are many other situations where conflict is shown. The main character, Karen Lorenz, experiences the most of this trouble. Conflict is the theme that is shown best in this story, because there are many situations that build up. We then see the resolution of each situation.   Ã‚  Ã‚  Ã‚  Ã‚  The story begins in spring on Easter Monday, April 2nd, of 1945. Karin Lorenz and her family live in the small town of Erfurt in Germany. The Lorenz family hears news that the Allied invasion is expected to be storming through into surrounding areas of Erfurt. Conflict is immediately shown here in that there is war taking place between Germany and the Allies. The advance of the Allies causes Karen to attempt to convince her family to escape to Eberstein, where Pastor Helmut Lobelius, Karen’s boyfriend, lives. Helmut had invited the family numerous times, but Karen’s father was against the idea because he is a doctor and needs to tend to his increasing number of patients. Karen’s parents also believe they are in safety because they deem that there is not much fighting left to do. This shows conflict in that Karen’s parents do not believe in her ideas. They think she is just an impractical girl with a silly idea, and they believe that eve rything will be fine with time. Word is then heard that Erfurt is in the path of the Allies and that the town is to be invaded soon. Karen finally persuades her parents they need to escape Erfurt while there is still time. At the close of the novel, the war resolves to an end. The Lorenz family returns home to a war-damaged Erfurt. Another resolution is that Karen grows more mature and her parents learn to listen to her more.   Ã‚  Ã‚  Ã‚  Ã‚  Karen’s brother, Till, is a very strong supporter of Hitler at the beginning of the novel. He was involved in the Hitler Youth Movement, called the H.J. Till was carefree, daring, and brave at the beginning. Till must leave the H.J. when the family leaves for Eberstein. While Till’s family is staying at Helmut’s, Till meets a girl who offers him work at her father’s farm.

Competition in Energy Drinks Essay

1. What are the strategically relevant components of the global and U. S. beverage industry macro-environment? How do the economic characteristics of the alternative beverage segment of the industry differ from that of other beverage categories? Explain. Demographics: The total sale for beverages in 2009 in the US was about 458. 3 billion gallons and it is one of the largest markets with dollar value of 1,581. 7 billion in 2009 and with a forecast of $1,775. 3 billion for 2014. 48. 2 percent of industry sales were from carbonated soft drinks and 29. 2 percent of bottle water industry sales. In 2009, The Alternative beverage industry included sports drinks, flavored or enhanced water and energy drinks made up 4%, 1. 6%, and 1. 2% of industry sales respectively. The global market for alternative beverages in 2009 was $40. 2 billion, while it was $17 billion for alternative beverages in US market. It was $ 12. 7 billion and $9. 1 billion for Asia pacific and European markets respectively. Market growth: The market growth has huge potential with the dollar value of the global market for alternative beverages grew at a 9. 8% annually between 2005 and 2009, but was expected to slow down to 5. 7% annually between 2010 and 2014. US is the country which has strongest growth internationally in term of alternative beverage sales with an annual growth rate of 16. 6% between 2005 and 2009 and a forecasted growth rate of 6. 7% between 2010 and 2014. Europe and Asia-Pacific grew at annual rates of 5. 3% and 5. 6% between 2005 and 2009 and were expected to grow at a rate of 4. 4% and 5. 1% respectively between 2010 and 2014. However poor economic conditions in the US in 2008 and 2009 led to a 12. 3% decline in sports drink sales and a 12. 5% decline in flavored and vitamin waters sales. It was also the reason why energy drinks sales increased only 0. 2% between those years. Rivalry between competitors: Coca Cola, Pepsico and Redbull are the three big players that made the industry rivalry become global. However, there were hundreds of brands like Otsuko which were specialty yet regional brands that did not have a foot print internationally but were doing well in their own terms. Beverage producers had made various attempts at increasing the size of the market for alternative beverages by extending existing product lines and developing altogether new products. Social Forces: * Global beverage companies such as Coca Cola and PepsiCo had relied on such beverages to sustain in volume growth in mature markets where consumers were reducing their consumption of carbonated soft drinks. * Expanding the market for alternatives beverages and increasing sales and market share, beverage producers also were forced to content with criticism from some that energy drinks, energy shots, and relaxation drinks presented health risks for consumers and that some producers’ strategies promoted reckless behavior, the primary concern of most producers of energy drinks, sports drinks, and vitamin-enhanced beverages was how to best improve their competitive standing in the market place. Driving Forces for this industry: * Expanding Market share. * Desire to reach out to Consumer needs and meet the demand * Personalization of the Market Segments * Branding * Market Size * Maximization of Growth Potential General Economic Conditions: * Global growth is projected to grow at 3. 5 percent in 2012, then accelerate somewhat to 3. 6 percent from 2013-2014. In 2012 It is expected that emerging economies will be slow in growth by 0. 7 percentage points on average, going from 6. 3 percent growth in 2011 to 5. 6 percent in 2012, partly as a result of slower export growth and partly because several of them have been growing above trend and the GDP Growth for the world is predicted to be at 3. 6. Things look a little slow but are picking up slowly and there is no recession in sight so far. This could really help the industries like Food, Beverages, Health surge ahead like they already are into the market with more percentage of market share and consumer usage based on the increasing numbers in the trend. Impact of Economic Factors: * Demand on beverages and alternative beverages should remain incremental or stable * Branded alternative beverages with national and international presence should do well * Business opportunities should be encouraged with fair and encouraging interest rates 2. What is competition like in the alternative beverage industry? Which of the five competitive forces is strongest? Which is weakest? What competitive forces seem to have the greatest effect on industry attractiveness and the potential profitability of new entrants? The Beverage industry is highly competitive and the segments that come into picture when it comes to competition are Distribution, Shelf management, Licenses, Brand name and Image, Pricing, Labeling and Packaging, Marketing and Advertising, Quality and taste, Trade and Consumer promotions and Branding. * Competition with non-alcoholic beverages * Competition with Carbonated beverages * Competition with regional beverage producers and private label soft drink suppliers * Competition in maintenance of distribution network * Competition on quality and pricing * Competition on Branding, Labeling, Marketing, Packaging and Promotions. Bargaining power of Buyers: Strong * Convenience store, grocery store, and wholesale buyers had considerable leverage in negotiating pricing and slotting fees with alternative beverage producers because of their bulk purchases. * New entrants with comparatively lower market shares are most affected with this like how it is mentioned in the case where the shelf space is limited to top brands like Coke, PepsiCo and Red bull for that particular market segment. The larger brands like coke and Pepsi also already have spaces worked out with them for their other products and this makes it easier for the bigger brands to get their newer products in the shelf’s too. * Delis and restaurants have low switching costs to other brands but they have less volumes compared to stores and less space, shelfs etc.and also will not have the same bargaining power that a store enjoys. * Demand is highly dynamic Bargaining Power of Suppliers: Weak * Suppliers for alternative beverages do exist in huge numbers and the competition is high * The producers of alternative beverages are important customers of suppliers and buy in large quantities. * Packaging is readily available Threat of Substitutes: Medium * Many substitutes like tea, bottled water, juices, nutrition water etc. have surfaced but the market is not as big as alternative beverages and this customer preference had weakened the competitive power of substitute beverages. * Many substitutes that can quench the thirst of the consumers * Price point of substitutes is less compared to alternative beverages Threat of New entrants: Weak * Brand leaders already exist in the industry with competitive prices and well established distribution system * Convenience stores and Shelves across the stores are already in partnership with existing big-wigs * Customer loyalty towards branded products is high * Need for large financial resources and funds * High Brand equity for already existing and successful brands Threat of Rivalry: Strong. * Competition centers among major brands based on brand image, appealing taste, packaging, R&D, Marketing and Distribution capabilities * Attempts by all the brands to increase the number and types of products in their product line * Low switching costs for the consumers of the industry * Strong marketing campaigns by each brand to gain customer loyalty The Bargaining power of consumers and rivalry that exists between the competitions in this industry contributes to the attractiveness of the industry. The numbers are promising, the industry is dynamic and increase in demand each year. The factors that affect the potential profitability of the new entrants are the Brand image, Distribution network and Product line breadth. 3) How is the market for energy drinks, sports drinks and vitamin-enhanced beverages changing? What are the underlying drivers of change and how might those forces individually or collectively make the industry more or less attractive? * Driving forces of the alternative beverage industry are dependent on the creating/sustaining market demand, dynamics of the growth rate and product innovation. * Industry leaders established: Segments within the alternative beverage industry have consolidated as markets have matured and leaders have been established. Red Bull GmbH and Hansen Natural Corporation remained independent in 2010, Coca-Cola controlled such brands as Powerade sports drink, Fuze vitamin-enhanced beverages, glaceau vitamin water and NOS. In addition, Coca-Cola distributed Hansen’s Monster energy drink in parts of the United States, Canada, and six European countries. * Changes in Long term Growth Rate: The recession had an impact on sales of sports drinks and flavored or enhanced water and has stalled growth in the market for energy drinks; there was also growing market maturity for most categories of alternative beverages. The annual rate of growth for the dollar value of the global market for alternative beverages was forecasted to decline from the 9. 8 percent annual rate occurring between 2005 and 2009 to an anticipated annual rate of 5. 7 percent for 2010 through 2014. While dollar value growth rates were expected to decline only slightly in Europe and Asia-Pacific, the annual rate of growth in the U. S. was projected to decline from 16. 6 percent during 2005 – 2009 to 6. 7 percent between 2010 and 2014 * Product Innovation: The industry is continuing to evolve with introduction of new products that enable rise of new category of products. The recent introduction of energy shots is an example of how an innovation that has given rise to an altogether new sub-segment in the industry. * The creation of new product segments, the increasing positive trends in growth rate and increasing market share for each product are a good indication and good drivers of change that increase the attractiveness of the market for an emergent industry. 4) What does your strategic group map of the energy drink, sports drink, and vitamin-enhanced beverage industry look like? Which strategic groups do you think are in the best positions? The worst positions? The strategic group maps show the industry participants competing with axes of Geographic foot print and Brand. The Map shows that Industry giants like Coke and Pepsico are positioned strongest in the industry due to already existing contracts, supply chain, distribution network and shelf spaces in retail spaces. * Red Bull is seeing a successful brand in Europe and the U. S. * Hansen’s Monster is also doing good standing up to the other market giants with distribution partnership with coke giving it the required space and opportunity to grab the market and hence can be considered at a favorable position. * Rock star has also been at a favorable position due to the same reason of distribution network partnership with PepsiCo * Companies with a single brand and regional distribution like Otsuko, Vitamin water etc. appeared to be at an unfavorable place with chances of competition gulping the market share of the small players very soon. 5) What key factors determine the success of alternative beverage producers? The Key success factors for Alternative Beverage producers are * Constant Product Innovation: A company must be able to identify what a consumer is looking for and also maintain the ability to adapt with the changing market trends. They must be able to keep up and not lag behind. * Price: Price is always a factors in many cases and in this case consumers with a low brand preference will buy a product based on its competitive pricing * Brand Loyalty: Consumers are particular about what brand they purchase and they stick to it in most of the cases. This stresses for a superior brand image and quality * Distribution system: Probably one of the most important, Effective distribution channels will not only help reduce costs but also helps a company remain competitive. * Size and Scale: Successful alternative beverage producers were required to have sufficient sales volumes to keep marketing expenses at an acceptable cost per unit basis. 6) What recommendations would you make to Coca-Cola to improve its competitiveness in the global alternative beverage industry? To PepsiCo? To Red Bull GmbH? Recommendations to Pepsi. * Pepsico have to launch a major image building campaign for the most promising products it has. * Pepsico also needs to develop its own energy shot brand try to convince Rockstar to add an energy shot to its distribution agreement. * In addition, Pepsi should negotiate for distribution rights to European and Asia-Pacific market with Rockstar or launch its energy drink brands in attractive international markets. * PepsiCo can expand its foot print and focus on other international markets in energy drinks for more international presence and to utilize the demand of a branded and standard product. * Red Bull is currently the number in the energy drinks category and they should really take advantage of that and come up with more product line extensions and more products so people can identify with that brand and try other products too. They should focus more on product innovation and product line extensions. Recommendations to Coca Cola * Coca cola should improve its product by innovating and building up good image to recapture the market share it lost in energy drinks category. * Coca cola should also try to create more rapid growth in vitamin-enhanced beverages and energy shots product. * Coke should focus on products and Branding efforts to gain market and regain lost market share in energy drinks * It should build up its strength in term of alternative beverage sales in by pursuing acquisitions and focus on building its strength of sales in Asia and react quickly to solve the problem of lacking competitiveness in the European market for alternative beverages. * Coca cola can use a combination of new flavors and formulations, brands, line extensions, improved image building, and distribution capabilities to increase sales of alternative beverages internationally. Recommendations to Red Bull GmbH * Redbull should improve the performance of its recently introduced energy shots and continue to expand into rapidly growing country markets for energy drinks. * It is necessary for the company to maintain its lead in the U. S. and European energy drink market with additional product line extensions based upon product innovation. * It should develop sports drinks or vitamin-enhanced beverages that can further exploit the appeal of the Red Bull brand 7. Using the data in Ex. 11, 12, 13 compare Pepsi, Coke, and Hansen. Who has been the most profitable? Who has better managed their expenses? Which business has shown the most growth? Which of the three would you give the strongest grade for their performance? * Using the data from Exhibit 11,12 and 13 for Coke, Pepsi and Hansen, Hansen seems to be the most profitable so far as it became the largest seller of energy drink in the US by leading most of alternative beverage categories. PepsiCo’s global market share in 2009 was 26. 5 percent, overcome by 11. 5 percent to Coca-Cola. The Coca Cola has better managed their expenses it was the third-largest seller of alternative beverage and in the top five best-selling non-alcoholic beverages worldwide in 2009. But they have lot of catching up to do. I would give the strongest grade for performance to Hansen for its market share, range of products, product innovation and distribution strategies. Hansen also managed to have higher revenue growth and higher cash flow growth. Net Revenue| 2007| 2008| 2009| CAGR| Pepsi| 39374| 43251| 43232| 3. 17%| Coca Cola| 28857| 31944| 30990| 3. 40%| Hansen| 904465| 1033780| 1143299| 4. 50%| | | | | | | | | | | Net Income| 2007| 2008| 2009| CAGR| Pepsi| 5674| 5166| 5979| 1. 76%| Coca Cola| 5981| 5807| 6824| 4. 49%| Hansen| 149,406| 108032| 208716| 11. 70%| | | | | | | | | | | Operating profit| 2007| 2008| 2009| CAGR| Pepsi| 7182| 6959| 8044| 3. 85%| Coca Cola| 18451| 20570| 19902| 2. 55%| Hansen| 230986| 163591| 337309| 13. 40%| The company growth rate analysis of the three companies in terms of revenue, income and profit show that Hansen has higher percentage of growth rate well above the industry average. Hansen has greater revenues in the industry segment and higher customer demand and financial success.
