Life is Calling: How Far Will You Go? :: Peace Core Essays

Life is Calling: How Far Will You Go? There are many organizations today that help great causes and one in particular that I find most imperative. The Peace Core is an organization whose foundation is set on volunteers who dedicate two years or more to a cause they find worthy of their time and energy. The amount of aid and support the Peace Core has given to numerous other countries is overwhelming. The number of countries served and how many people have benefited are just a couple of the notable statistics the Peace Core has achieved. Besides these statistics the Peace Core has something else to offer, inspiration. The Peace Core inspires. Helping others, taking a risk, going somewhere new, experiencing something hands-on are characteristics of the Peace Core that are never left unsaid. Unlike other organizations where money is donated and occasional fundraisers are held, the Peace Core offers a personal experience. The stories and memories will never be lost or forgotten like twenty dollars easily can, wh en it is handed over without distinction to some other organization. There are three websites that portray the values and influential qualities of the Peace Core and I encourage people to explore them here and discover the goals and characteristics of the Peace Core that humanize our lives. In 1961 John F. Kennedy challenged the students of the University of Michigan to live and work in a foreign developing country to help bring peace and education. The challenge that Kennedy proposed, inspired the organization known as the Peace Core to develop. The Peace Core was officially established on the first of March in 1961. Today, the Peace Core has gone global and is recognized for its accomplishments in AIDS/HIV education, technological and business development, and restoring the environment. The principle of the Peace Core is to bring world peace and friendship between countries. The Peace Core is solely made up of volunteers to further display that the Peace Core is not money oriented but goal oriented focusing on bringing education and happiness to people and countries that need it. The Peace Core is such a huge organization and is the subject of countless websites.

The Chemistry of Blood Colours

Blood is a necessary component of the majority of living organisms (all vertebrates and some invertebrates); it carries vital nutrients, oxygen and proteins to body tissues and carries away waste products. Blood, although most commonly red, can also be found in such colours as green, blue, clear, pink and violet. However, the common misconception surrounding the idea that human blood is blue before oxygenation is false. All human blood is varying shades of red; these wild alternate colours are found in other animal species such as certain species of crabs and insects. This colouring of the blood can be seen as an indicator of oxygen carrying ability or make apparent the metal with the highest concentration in the blood. The colour containing portions of blood are known as respiratory pigments; these pigments are metal containing proteins which combine reversibly with oxygen. Respiratory pigments are found within cells of blood and their primary function is to aid in the transportation of molecular oxygen. There are four unanimously recognised respiratory pigments, these are; hemoglobin, followed by hemocyanin, then chlorocruorin and Hemerythrin. These four pigments occur in greater percentages and are far more efficient in carrying oxygen than the few other pigments known. These lesser known pigments (not all fully recognised as respiratory pigments) include; vanadium chromagen and pinnaglobin. Haemoglobin, the most common respiratory pigment on earth is the pigment found in all vertebrates (excluding a few Antarctic fish) including humans. Hemoglobin is located within the platelet component of blood giving the distinctive red colouring associated with blood both when oxygenated and deoxygenated, when oxygenated it is a bright red and by the time it is traveling In the veins back to the heart, blood containing haemoglobin is a dark red in colour. This colour is due to the presence of iron in the haemoglobin. Iron is the central atom of the heme group ( Without iron in the heme group, there would be no site for the oxygen to bind) One molecule of haemoglobin, with iron at the centre, can carry four oxygen molecules. Fig 1: Hemoglobin structure Image: (Wikipedia, the free encyclopedia, 2013) Fig1. 2: Hemoglobin, human adult, heme group Image: (Wikipedia, the free encyclopedia, 2013) Hemocyanin is the second most evident form of respiratory pigment, found in mollusks, arthropods and some insects. Blood containing Hemocyanin is blue in colour when oxygenated and transparent in appearance when deoxygenated. Oxygenation causes a colour change between the colorless Cu(I) deoxygenated form and the blue Cu(II) oxygenated form. This blue colour is due to the presence of Two copper atom at the centre of hemocyanin particles and unlike haemoglobin, only two oxygen molecules can reversibly combine with the metal proteins at the centre of the hemocyanin particles therefore it is four times less efficient as an oxygen carrier than haemoglobin. Fig. 2: Hemocyanin, deoxygenated and oxygenated Image: (htt) Chlorocruorin is an iron, metalprotein, respiratory pigment with many similarities to hemoglobin. The most notable of the differences between hemoglobin and chlorocruorin is the abnormal heme group structure of chlorocruorin and unlike hemoglobin it floats freely within the plasma of blood rather than being confined to red blood cells. The chemical colour change of chlorocruorin bears resemblance to both hemoglobin and hemerythrin, changing from a green when deoxygenated to red when oxygenated (two oxygen molecules reversibly combine one iron atom). This ration puts chlorocruorin at 25% the efficiency of hemoglobin. Fig. 3: Chlorocruorin structure Image: (Wikipedia, the free encyclopedia, 2013) Hemerythrin is the third respiratory pigment containing iron, found in marine invertebrates (sipunculids and brachiopods) and used for oxygen transfer and/or storage. Although containing the same metal protein, hemerythrin differs from both haemoglobin and chlorocruorin as it contains two more iron atoms which reversibly combine and are connected by an oxygen molecule. This means that the efficiency of this pigment is 25% as effective as haemoglobin and on par for effectiveness with chlorocruorin. When the oxygen molecule combines directly (no heme group) with the iron atoms a colour change occurs; deoxygenated hemerythrin is near colourless changing to a pink/violet colour when oxygenated. Fig. 4: Hemerythrin structure found in sea worms Image: (Coleman, 2009) Other than the four major respiratory pigments, giving blood colour, there is dispute over two other pigments, little is known of these pigments. They are; Pinnaglobin, a brown pigment found in the blood of a mollusc of the genus Pinna, this pigment demonstrates similarities to the pigment Hemocyanin but contains manganese as the metal atom in place of copper. The other proposed pigment (idea is disputed) vanadium chromagen, is said to be light green in colour, contain metal atoms of Vanadium and is found in sea squirts, ascidians and tunicates.

Management Problem in Health Care Essay

Management Problem in Health Care Worldwide health care organizations are faced with problems everyday. Motivation is one of the many management problems in health care organizations today. Health care organizations are always working together to come up with ideas and strategies to make their organizations more successful and better for everyone to work in as well. Problem solving is an on going process in health care organizations, which have been bringing positive results for everyone working in the health care organizations. Motivation is a state of feeling or thinking in which one is energized or aroused to perform a task or engage in a particular behavior. This definition focuses on motivation as an emotional or cognitive state that is independent of action. This focus clearly distinguishes motivation from the performance of a task and its consequences. Notice, too, that motivation can be a state of either feeling or thinking, or a combination of the two. For some individuals, motivation is more a matter of feeling than thinking, while, for others, the reverse is true† (Shortell & Kaluzny, 2006). Motivating the people who are working under management can be a difficult task at times. Everyone is unique, none of us are the exact same and each person needs something different to become motivated and that is where the challenge comes in for the managers, finding the right motivator for the right employee. Knowing and caring about the employees needs, will help managers know what type of rewards to offer as a way to motivate their employees. Management Problem 3 The success of any organization, especially health care organizations solely depends on the skills of managers and how they present the work environment for their employees. When employees are motivated they tend to be more satisfied with their jobs and will stay with the organization much longer as a result of their satisfaction. According to a recent survey from the Healthcare Information and Management Systems Society offers some ideas on how to keep them happy. â€Å"First, pay a decent salary, â€Å"that came through loud and clear in the survey†, says Linda Hodges, executive vice president of search firm Hersher Associates, which conducted the survey with HIMSS. Salary was identified by the survey’s 361 respondents as one of the main factors they use to evaluate job satisfaction or a job offer. Forty percent of those surveyed said they don’t believe they are paid market value† (Greene, 2002). According to Lynn, â€Å"if your program examination indicates that you have done everything right but the results were not there, it is time to talk with people one-on-one. Ask each employee why the program did not have the impact you were looking for. They may have been trying as hard as they could, but only delivering a marginal performance. It is possible they are battling obstacles you cannot see. To find out what is getting in their way, ask them how you can help them improve† (Lynn, 2001). Asking these questions are important when it comes to keeping your employees involved in everything, always getting their opinions on how they think it should be done and work together as a team to come up with the best solutions. This is what a good manager is made of, including his employees in everything that has to do with the job. Management Problem 4 Maslow’s theory was unique because he believed that each person had five needs and each need had to be met before they could go on to the next need. As the process went on, each old need lost motivational value as the new need was met. According to Shortell and Kaluzny, â€Å"Maslow’s hierarchy of needs assumes there are five need levels that must be satisfied sequentially. 1. The physiological needs, these needs include things like air, water, food, warmth, shelter, and sex, the basic survival needs. 2. The security needs include a secure physical and emotional environment, examples include the need to be free from worry about money and job security. 3. Belongingness needs involve social processes, they include the need for love and affection and the need to be accepted by one’s peers. 4. Esteem needs are actually composed of two different set of needs: the need for a positive self-image or self-respect and the need for recognition and respect from others. 5. Self-actualization needs, at the top of the hierarchy, involve realizing one’s potential for continued growth and individual development† (Shortell ; Kaluzny, 2006). Although, Maslow’s hierarchy of needs theory seems too simple for the human body, which is very complex, this is the perfect theory of motivation for us. This theory touches every aspect of our lives and how one feels about themselves and their surroundings. People who are in management positions will be wise to use this theory when it comes to motivating their employees, in any industry health care or otherwise. It does not matter which theory you think may be best to follow, interesting work and employee pay are the two biggest motivators. Management Problem 5 After identifying the motivation problems with the employees, managers need to start right away working on a plan to overcome these problems. They can start with talking with each individual employee and ask them questions. Making the employees feel like they have a part in finding the solution is a big part in motivation too. Everyone needs to feel like they are helping in some way or another. In conclusion, even though motivating your employees is a difficult task, it must be done in order to keep them happy and to keep things running smoothly. Keeping your employees happy can only bring success to their organization. The employees will love doing their jobs and they will do them well, they will come to work everyday and this will result in a cost effective organization, because the turnover rates will be less in each organization and the organizations will not have to worry about training new employees.
