5 Basic Principles Of Energy Security

5 Basic Principles Of Energy Security Energy security is put in first place among the priorities facing the European Union. Although the problems of ensuring energy security were standing in front of a united Europe from the beginning of the integration process in recent years they have acquired the greatest relevance and importance for the EU. This is due to the fact that today the EU depends 50% on external energy supplies to its market and on the policies pursued by supplier states. In addition, European countries are concerned about the well-known problems with the energy supply for them against the backdrop of turmoil between Russia, as the main EU energy supplier and Belarus and Ukraine, through whose territory the Russian hydrocarbons are delivered to the West. Russian-Ukrainian standoff on the issue of gas prices and transportation is the major concern of EU member states and compel them to talk about the need to diversify energy supplies. Concentrating 7% of world population, more than a quarter of world GDP and 20% of world trade, the EU has only 2% of the worlds black gold and 4% natural gas. Limitation of its own resource base in Europe accounts for a significant dependence of the EU on external energy supplies. The European natural gas market is the third largest in the world. The volume of gas consumption in EU countries reached 513 billion m3 (21% of world consumption). Russia is the second largest EU oil supplier and provides 33% of the EU black gold needs. The Russian Gazprom is the leader in EU natural gas supplies with 46% of total. If we talk about security of energy supplies, the main task in this area is the energy sectors geographical and resource diversification i.e. the expansion of supply sources, supply routes and pipelines. The EU security in energy sector NABUKO I EU The European Union is seeking to protect self from energy dependence on Russia with diversification of natural gas supplies policy by agreements with non-conventional energy suppliers, the Caspian states (Caspian states have only 4-5% of worlds gas reserves). But due to the unreliability of Russian energy supplies through third countries (Belarus and Ukraine) as well as the possibility of using Russian resources as a political tool, transporting Caspian Sea hydrocarbons (Azerbaijan, Kazakhstan and Turkmenistan) to the West has acquired great importance to the EU. Improve supply reliability and energy security EU responsible implementation of the Southern Gas Corridor. The planned corridor is composed of three parts: the Trans-Caspian gas pipeline (the project provides for delivery of natural gas from Kazakhstan and Turkmenistan to Azerbaijan), Baku Tbilisi Erzurum (from Azerbaijan through Georgia to Turkey) and Nabucco (from Turkish territory, via Bulgaria, Romania, Hungary Austria). Thus, the reliability of energy supply in Europe is due to the changing geography of supply, increasing the number of exporting countries, the creation of new infrastructure facilities. In the face of increasing competition from non-traditional suppliers of hydrocarbons Russia is very important to maintain the competitiveness of their energy in the European market, to ensure effective and reliable conditions for their transit to Western Europe. From the European Union course to diversify energy imports implies Russias post-Soviet space deterrence, to avoid direct or indirect control by the latter over the mining sector and transit infrastructure in surrounding areas. Revealing in this regard, the role of such organizations as the GUAM (Georgia, Ukraine, Azerbaijan and Moldova), which can be an active participant in non-Russian energy supplies to European markets. Major energy projects GUAM is the White Stream. White Stream the idea of the Ukrainian side to diversify natural gas supplies to Europe and Ukraine and reducing dependence on Russia. According to the concept of developers this pipeline should pass along the Eurasian oil transport corridor, i.e. from Azerbaijan to the Georgian port of Supsa, and then across the Black Sea to Ukraine and onward to the EU, bypassing Russia. From a geopolitical point of view, the creation of transport corridor from east to west, bypassing Russia, on a plan of Brussels, will: To diversify energy supplies to reduce dependence of the EU from Russia and thus ensure energy security; Dismantle the transport system of the former Soviet Union, largely through the territory of Russia and provides strategic control over the export of Central Asian energy resources; Open the path to European Union cooperation with countries seeking to establish independent from Russian energy transportation routes; Establish control over the hydrocarbon resources of the region and not to allow these resources were available to Russia; At the expense of control over energy resources to ensure the establishment of political control over the countries of the region; Set the geopolitical pluralism, independence (from Russia), the newly independent states. Implementation of the EU projects such as the Nabucco, whose design capacity is 30 billion m 3 of gas per year, is a complex challenge for the Russias national interests towards Europe and tangibly affect Russias foreign policy and foreign economic activity. Russian energy resources development and policy Energy policy Russias European direction is traditionally occupies a leading position in trade of fuel and energy resources. The EU has come 53% of Russian oil exports and 62% natural gas. For Russia, with its unique geographical and geopolitical position, the problem of transit of energy resources are of particular importance, since it depends on the transit of hydrocarbons in the main markets of third countries. This implies the task of ensuring uninterrupted supplies of Russian energy exports to Europe. Improving energy security EU calls for Russia to develop and implement a wide range of policy and energy initiatives aimed at diversifying sources of supply of hydrocarbons. Passionate desire of Russia to find new routes for transporting oil and gas to the EU, bypassing the neighbors (Belarus and Ukraine), good reason: a choice of routes is important because it allows not depending on the mood of the transit country. Currently, construction of the North European Gas Pipeline Northern stream » (Nord Stream) will run under the Baltic Sea from Vyborg, Russia to Greifswald Germany. Capacity will be 55 billion m 3 of natural gas per year. Implementation of this project will help solve the problem of diversification of export flows of gas, will expand supply in Western Europe and the implementation of Russias obligations under the concluded and the future long-term contracts for the supply of natural gas. The second project is the South Stream (South Stream), which will run under the Black Sea from Novorossiysk to the Bulgarian port of Varna, and then divide into two branches and will pass through Serbia and Hungary to Austria through Greece to southern Italy. Capacity will reach 60 billion m 3 of natural gas per year. The main objective of these projects is to provide direct communication between the seller (Russia) and customers (Western, Central and South-Eastern Europe), bypassing the territory of Belarus and Ukraine, through which the now Russian natural gas to the EU through pipelines Urengoi Pomary Uzhgorod and Yamal Europe. As a Eurasian power, Russia is naturally interested in a free hand in its energy policy in all directions. At the end raises the question of correcting the current asymmetry of Russian energy exports in favor of the eastern direction. Russias national interest is to diversify markets for energy resources, expanding the geography of supplies of hydrocarbons. Due to this, Russia reduces dependence on the potential risks and, of course, opens up new and promising markets. To enter the Asia-Pacific region will create a pipeline Eastern Siberia Pacific Ocean (ESPO) pipeline, which would connect the oil fields of Western and Eastern Siberia to the ports of Primorsky Territory in Russia and provide access to the markets of the Asia Pacific region. This pipeline capacity of 80 million tonnes a year must pass from the Taishet (Irkutsk region), north of Lake Baikal through Skovorodino (Amur region) in the Pacific Kozmino Bay (Primorsky Krai). The priority of Russian foreign energy policy includes the construction of a branch in China from being built oil pipeline Eastern Siberia Pacific Ocean. Power outlet will be 15 million tones a year. The implementation of the above projects will provide an opportunity to solve simultaneously the two most important geo-economic and geopolitical objectives: provide a way out of Russian crude oil to the rapidly growing market of the Asia and the Pacific region and reduce dependence on the main buyer of energy. Tendencies of development of world energy markets and energy security issues Malo history, why energy is needed, crucial statistics In our fast developing world, according to recent prognosis, energy consumption can grow up to 30% within next 15 years. World oil demand can became higher for 42% and natural gas consumption will rise for about 60%. Todays world market is characterised with four most important circumstances: sharp rise of energy demand in developing Asian countries (up to 45% of perspective world growth in oil consumption) increasing gap between demand and production volume of gas in economically developed countries (for example, by 2020 between 60% and 70% of gas consumption in Europe will be provided with the account of imports) insufficient capacity for the production, processing and transportation of oil and gas as well as the limited possibilities of new sites insufficient transparency of world energy market All these conditions presented to the fore the problem of energy security. Also, the globalization process with which the world has faced in the twentieth century, directly affect the sphere of world energetic  [1]  . The enormous energy demand growth in Asia intensified competition for stable and cheap energy sources and in many parts of the world (especially rich in energy resources) occurring instability and conflicts. These circumstances contribute to energy instability and large fluctuations in energy prices. World reserves of cheap energy are reduced, crossed the zenith of production while consumption is growing steadily. In light of these circumstances should be considered global processes in the energy sector. If we take in consideration allocation of worlds energy reserves, it can be seen that every part of the world has some reserves or reserves are allocated within reasonable range (e.g. Russia energy reserves are sufficient to cover rising European demand, Gulf of Mex ico and Venezuela reserves are most convenient to America) Dijagrami. Experts assessment say that there is sufficient energy reserves, but the cost of exploitation going to be sufficiently higher. World of cheap and accessible energy is definitely behind us. It is necessary to mention climate change and slowly growing tendency of reduction in CO2 emissions which will affect the consumption of fossil fuels but the global demand will not be reduced. Achieving global energy security will be reached by the world community implementation of measures in three main areas: Reliable supply of the world economy traditional forms of energy; Increase the efficiency of energy resources and environmental protection; Development and use of new energy sources. All world and especially developed countries and largest energy suppliers have to contribute to achieving energy security. Basic principles of energy security Despite all the differences in the approaches of major states, there are common points in the understanding energy security. In fact, it is possible to isolate the basic principles that are more or less shared by all states. Energy security is the mutual responsibility of both the energy consumer and the energy supplier. This is acknowledged by all, but the problems arise where the consumer and provider begin to demand each from other guaranties of supply or pay for these supplies. For example, in a moderate variant, the demand for guaranties of supply can lead to the consumers request to allow him representing the economic interests of the company for development and transportation of energy resources in the provider country. This is the case where the EU requires from Russia opening its energy sector for European investments. On the other hand, Russia sets requirements of direct accessing to the customer delivery systems. In the radical version assurance of supply can be expressed in direct political and economic dictation towards supplier country, up to carrying out military operations against them. Also, in the recent history we have witnessed that supplier country can impose measures such as deliver y cutoffs, which affected not only targeted countries but many others (Russia Ukraine and Russia Belarus disputes). However, there is a third option, presented by Asian countries. It is the willingness to guarantee delivery due on the one hand, the participation of companies representing the economic interests of consumers in developing energy resources in the provider country, on the other playing by the rules of the provider country and investing heavily in infrastructure, mining and transportation. In this case, it is not a simple commodity-payment scheme, but a more complex investment, insurance and other contractual relationships. The consumer provides his assurance of supply at the expense of investment in infrastructure provider, so as to optimize the supply chain, making it more modern, less costly, etc. Suppliers, allowing consumers to develop projects in their territory introduce not only secure and stable market, but also a strategic investor. Thus, we are talking about the principle of responsibility and interdependence of consumer and provider  [2]  . Further, despite the limited number of countries that act as energy suppliers, development of events shows that there is competition between them; moreover, the very limited number of suppliers can toughen this competition. Factor that stimulates competition among providers is definitely another principle called diversification of sources and suppliers. At the moment there is competition between energy suppliers and it must also be built into the system of global energy security. The most important condition for this is the energy security depoliticization. In fact, the competition based on economic principles, competition for consumers is logical and understandable phenomenon. However, any use of energy resources for political purposes in the situation of rising demand leads to conflict, consequences of which can be unpredictable. Every attempt to put energy as a subject of political conflict is challenge to the global energy security system. Thus, the principles of energy security are also the depoliticization and fair competition. Moreover, if we can present the competition between suppliers, it is much more serious phenomenon the competition between consumers. The global reduction of energy production will imply the competition among energy buyers and consequently instability in particular regions could appear. Economic development without stabile energy supply is impossible. Therefore, overcoming global problems such as poverty, epidemics, poor education, environmental challenge, without economic stability is unattainable. Energy supply and demand, market competition, joint investments, global warming, CO2 emissions, joint stability and many other factors indicate that energy security is primarily a global issue so we can point at another principle, the principle of globality.. In this context, we should not forget that energy security is inseparable part of a global security system. Looking the importance of energy for the quality of life and life in general, it is necessary to emphasize the principle of social orientation of energy security for both individual countries and the world at large.

Angelas Ashes - Brief Plot Summary :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  In Angela’s Ashes, the author Frank McCourt gives his whole self in the telling of this story. It is his life’s journey- the hardship, horrors, pain and suffering that he endures.   Ã‚  Ã‚  Ã‚  Ã‚  Set in 1936, Angela’s Ashes follows the difficult lives of Angela McCourt, her husband, Malachy and their children. The oldest child of the family Frank McCourt was born into the worst kind of poverty in Brooklyn, New York. Frank and his family wore nothing more than rags and the little food they had came from the charity of kind people. His mother, Angela didn’t work and his father always drank his paycheck away. Even with out steady income to support one child, the McCourt family kept on growing extending to Malachy, Margaret, the twins- Eugene and Oliver, and eventually Michael and Alphonsus. Thus, beginning at a young age, Frank had the responsibility of tending to his brothers and sisters while his mother was desperately trying to find food to feed the family, and his father was getting drunk in the bars.   Ã‚  Ã‚  Ã‚  Ã‚  Although Frank’s father was not around for most of Frank’s life, Malachy did nurture in Frank an appetite for the one thing he could provide: a story. Throughout Angela’s Ashes Frank lives for his father’s tales of Cuchulain and The Angel on the Seventh Step, Frank’s very own angel who also brings his mother babies. â€Å"Would the Angel on the Seventh Step tell you what to do, if you didn’t know what to do?† â€Å"He would son, he would. That’s the job of an angel. Even the one of the Seventh Step.† I know he’s there because the seventh step feels warmer Than the other steps†¦ (Pg.125)   Ã‚  Ã‚  Ã‚  Ã‚  After the death of Margaret, the McCourts move to Ireland where the situation only worsened. Frank’s father continued to drink the money away and most nights the family was left to starve. â€Å"I want ye to stand in the middle of the pub and tell every man your father is drinking away the money for the baby. Ye are to tell the world there isn’t a scrap of food in this house, not a lump of coal to start the fire, not a drop of milk for the baby’s bottle.† (Pg.183-184) Life for the McCourts was testing and difficult. The children wore rags for diapers, Malachy and Frank wore torn shoes in the winter, and Angela was forced to gather scraps of coal and paper from the roadside just to light a fire.

Sexual harassment is another subject of interpersonal communication that occurs in the workplace. Although sexual harassment violates Title VII of the Civil Rights Act of 1964 and as amended by the Civil Rights Act of 1991, it is still a reality in all places of employment which is why it is something that everyone should have the ability to identify, understand, and effectively respond to. The U.S. Equal Employment Opportunity Commission defines sexual harassment as follows: Unwelcome sexual advances, requests for sexual favors, and other verbal or physical conduct of a sexual nature constitute sexual harassment when this conduct explicitly or implicitly affects an individual's employment, unreasonably interferes with an individual's work performance, or creates an intimidating, hostile, and offensive work environment. Sexual harassment can take place between any two individuals: any gender to any gender, any business, school, place of social, religious, and political organization, authority to subordinate, subordinate to authority.The DeVito text separates this definiti...

History of the Violin and Bow Essay

Stringed instruments such as the violin and its accompanying variations have been used in music for thousands of years. The first officially recorded use of the violin was during medieval European times. The earliest form of the violin was referred to as a Fiddle and the person playing it was termed as a Fiddler. During the 15th century though, the violins began taking on a new shape and began to carve its own history in music. The evolution of the violin continued into the 16th century when it developed what was to become its final look and shape. It is this artistic representation of a violin that we still recognize and use in our present time. An Italian from Cremona named Andrea Amati, is recognized as the founder of the most famous violin making school. The violin making school is not a structure per se but more of a school of thought and characterization. It was during this time that an explosion in violin making reached as far as Europe even as Cremona remained as the home of the best violin makers in the world. The most famous of these violin making families are the Amati, Guarneri, Antonio Stradivari, Rugerri, and Bergonzi. In the music world, the finest musicians openly acknowledge the Stradivari and Guarneri violins to be the best violins ever made over the past 150 years. The Violin is a member of the string instrument family and is capable of producing a 3 octave sound range when played by skilled musicians. The sound a violin creates depends on a number of factors, the most important of which are the type of wood used to produce the body of the instrument and the type of metal strings used.. It is usually 14 inches in length and uses metal strings tightened to various degrees on tuning pegs, to produce its exceptional sound quality. A typical violin is composed of the following parts: Chin rest, F-hole, strings, tuning pegs, scroll, tailpiece, fine tuners, bridge, belly, fingerboard, neck, and back plate. The sound is produced by the instrumentalists skimming a bow over the metal strings. Violins are usually constructed to withstand the 17 pounds of downward force that is regularly applied to the 4 metal strings. But just like any stringed instrument, the Violin in itself will fail to make sweet music for the listeners if not strummed with a bow. The bow is the instrument by which a Violinist makes his instrument sing. His expertise in the use of the bow produces the violins varying tones and pitches. How a bow is shaped and the different parts that form the bow all work together to form the best bow for violin playing. A bow is most often described as an arc shaped piece of wood that has a flat horsehair piece stretched and tensioned across the wood. The tips of the bow are pointed on one end and rounded on the other. Although the violin enjoyed various incarnations as it gained popularity and was played by chamber and orchestra musicians, the violin bow did not keep up with these changes. This led to a total redesign that resulted in what is known as the modern bow. The modern bow is believed to have first made its appearance in France during the 19th century at the hands of the Tourte family. The Tourte family is considered by the violin historians to be the bow maker equivalent of the Stradivari family in violin making. The modern bow has more tension and resistance and uses Pemarnbuco wood as wood stick. Sometimes, makers will add subtle modifications to the bow in the hopes of producing a more handy and usable bow. Admittedly, not much has changed in the 150 year history of the bow. The violin and bow can be thought of in terms of milk and cookies or coffee with cream. One always enhances the best aspects of the other in order to produce a very significant experience for the person whose auditory and sensory perceptions participate in the resulting enjoyable final product of the merging of the 2 instruments.

Sociocultural Influences on a Person’s Attitude Towards Physical Exercise and Heath

Sociocultural Influence’s on a person’s attitude towards Physical Exercise and Health. Humans are by nature social beings. In trying to determine what makes us feel fulfilled, psychologists have found that a feeling of social connection or relatedness is near the top of the list of what we need to experience. We appear to be happiest when we successfully connect with others. Much of what we say and do is motivated by a desire to appear likeable, to gain social approval, to solidify group membership, to manage self-image, or to gain social support.Sociocultural factors that influence a person’s attitude towards Health and Physical exercise can be classified into three groups. They are * Self-presentation * Social Influence (social norms and persuasion) * Social support Self-presentation The number one most influential factor on how sociocultural influences do have on one’s attitude towards health and physical exercise. Self-presentation is where a person tr ies to influence others on the perception of their own image.People make many different attempts to manage how others’ view them because other people control many of the things we want to obtain, such as friendship, financial resources, or career advancement, we strive to gain others’ approval or avoid rejection. In exercise and physical activity settings, these attempts to present ourselves favourably may have either positive or negative effects on our strivings to be physically active. For example, Tim is slightly overweight and has dietary habits that aren’t exactly the best and decide to join a gym.Tim doesn’t want to go and run on the treadmill next to a super fit world class athlete because his figure and athletic ability are notably different and he doesn’t wish to embarrass himself. We see in this example that Tim has this idea that because he isn’t the same as the super fit world class athlete that he isn’t healthy and theref ore he is reluctant to exercise because he’s afraid of embarrassing himself. It’s people like Tim that are changing who they are and what they are trying to achieve because of either the public opinion or their friends opinion.Self-presentation is a major factor in influencing a person’s attitude towards health and physical exercise and the way they general perceive themselves in amongst the group or the community. Social Influence Following in contributing factors that influence a person’s attitude towards health and physical exercise is Social Influence. Social influence is when an individual's thoughts, feelings or actions are affected by other people’s opinions. If you have ever been in an audience at a large musical or theatrical performance, you may have noticed that the audience tends to clap in unison and stop clapping at the same time.You may have even started to clap when no one else did only to feel foolish and quickly stop clapping. Wha t you are experiencing in these situations is the power of social influence – specifically, social norms and conformity. Social influence can be defined as a real or imaginary pressure exerted by others that shapes our behaviour. While self-presentation describes our actions or attempts to project a positive image to others, social influence describes the pressure exerted by others to influence our action.In exercise and physical activity settings, there are numerous examples of the power of social influence. Joining a fitness club because other friends pressure you join, or your teenager’s desire to buy the latest pair of basketball shoes because Michael Jordan wears them and touts them on commercial television are both examples of the power of social influence. Social Support Finally, the last group called Social Support. Social Support provides reassurance and/or assistance, information or feedback through contact with other individuals or groups.People do not exerc ise merely to look good in other’s eyes or because we have been persuaded by others to do so. Sometimes people exercise because they obtain social benefits from physical activity participation. An example would be Fiona is out running on her own and feels vulnerable and exposed and feels like everyone else watching is laughing at her. She joins a gym group that runs regularly and finds comfort in the fact that she isn’t the only person who may be struggling. The frequency or type of social contacts may have a strong influence on the general well-being of the person as we see in the example.As a whole, physical activity participation appears to be nurtured when there is a socially supportive atmosphere or when participants perceive social support when striving for their exercise goals. Plus having feedback from others that boosts their self-esteem helps and allows them to have the opportunity to find a group in which they feel comfortable and are supported emotionally a nd tangibly and are able to obtain useful guidance or advice from other exercisers, friends, family, or exercise leaders.In conclusion, the contributing factors mentioned above have a significant impact on the entire health spectrum. Emotional, Physical, Mental, Spiritual and Social aspects are all affected in how sociocultural factors influence a person’s ability towards a healthy lifestyle and staying physically active.

Caravaggio’s The Denial of St. Peter

Caravaggios The Denial of St. Peter   Ã‚  Ã‚  Ã‚  Ã‚  In approximately 1610, Michelangelo Merisi, referred to today as Caravaggio by virtue of his hometown, painted his The Denial of Saint Peter, an oil-on-canvas depiction of St. Peter’s renunciation of Jesus and disavowal that he was a disciple of Christ. Though it passed through the hands of several cardinals over the centuries,[1] the work itself was not commissioned by any religious authority, and was entirely conceived by Caravaggio. It currently is on display at the Metropolitan Museum of Art.   Ã‚  Ã‚  Ã‚  Ã‚  The most important aspect of the work stems from its era: Caravaggio painted in the early Baroque period, a time in art largely focused on emotion, drama, and realism in the portrayal of humanity, as opposed to the idealized, somewhat emotionless scenes of the Renaissance.[2] The Denial of Saint Peter is a prime example of this trend, for, as opposed to depicting idealized human forms in a heavily structured and adorned setting, it portrays jus t three figures, all of whom are imperfect, human, and express clearly visible emotion. While Caravaggio’s subject matter is far from unique, his distinctive approach toward its illustration is revolutionary with respect to earlier Renaissance art; of course, it resembles other works from the Baroque period, which Caravaggio himself helps to usher in. The drama and emotional anguish of Caravaggio’s work is apparent even upon first glance. Upon examining the figures in the work, we see that Saint Peter is far from flawless and virtuous; instead, he is easily intimidated by a soldier as he frantically distances himself from Christ, pointing at himself incredulously as if to appear utterly surprised at the notion that he is somehow associated with Jesus. Peter lacks the saintly character attributed to Biblical figures in earlier works, for he has deeply furrowed brows and looks pale and sickly in the harsh light shining on him-in fact, he more closely resembles a cowardly man eager to appear common and nondescript. The woman and the soldier have powerful emotional elements in their depictions as well-the soldier appears threatening, seemingly warning Peter of the consequences of allying with Christ, while the woman bears a stern expression that signals her certainty of Peter’s solidarity with Jesus. Finally, the sheer size of the figures is noteworthy, for it places all emphasis on them and on no other point in the painting. Caravaggio’s stylistic effects, in addition to the figures’ expressions, also lend the painting a dramatic air. The first and most obvious such technique is his use of lighting: specifically, the work has extreme contrasts between light and dark, which, due to their harsh appearance, convey an almost theatrical impression to the viewer. In fact, Peter’s head is fully and strongly illuminated, while the soldier’s visage, though just opposite his, is barely visible; the woman’s face, furth ermore, is alternately obscured and lit-with little or no attempt to mediate the two extremes. This consistent use of dramatic lighting, which in this case radiates only from the left of the painting, is termed â€Å"chiaroscuro†; in fact, Caravaggio used it so often that his version of the technique is labeled â€Å"tenebrism.†[3] The effect that these techniques have on a work is profound, for they create a powerful sense of tension in the piece because of their stark, almost jarring appearance. In The Denial of St. Peter, this effect is quite noticeable, for by illuminating Peter, but not the soldier, the sense that Peter is being interrogated and pressured becomes heightened; it is almost as if a spotlight is on him, coercing him into giving a reply.

Inprovement science Article Example | Topics and Well Written Essays - 500 words

Inprovement science - Article Example iplinary team at Pacific Oaks Hospital has noted a rise in pressure ulcer rates and considered setting up strategies to decrease the pressure ulcer rates. Several models have been developed to improve the quality of human health (Sadeghi, Barzi, Mikhail & Shabot, 2013). Among the various models developed include the Public Heath Model and the Model for Improvement. The purpose for this project is to evaluate the Public Health Model and the Model for Improvement to assess how they can aid in decreasing the pressure ulcer rates. The public health care model is among the most important models ever developed. The model incorporates a variety of prevention and care strategies. Gilbert (2011) states that the model focuses on the causes of disease, socio-cultural and economic factors that might interrupt the quality of healthcare services. The model is characterized by unique elements such as leadership, surveillance, and partnerships. The model can be adopted to improve the quality of service and welfare of people suffering from pressure ulcer disease. Actually, the model can be employed in developing effective prevention, rehabilitation, and palliative care strategies at different stages of disease development. For instance, surveillance can enhance timely detection of the diseases. As a result, prevention schemes will be established on time and, therefore, reduce the identified pressure ulcer rates. The model emphasis on teamwork and strategic performance. However, the model directs that the size and nature of the team should be determined by the needs and nature of the organization. The model explains that it is important to set goals that the improvement strategy intends to achieve. According to Hickey & Brosnan (2012), setting of goals gives the team a roadmap of whatever it intends to achieve. The model reflects on the importance of establishing measures and selecting changes. In essence, establishing measures aids in assessing whether adoption of a specific
