Developing Good Work Ethics Essay Example

Developing Good Work Ethics Paper As a social actively Its purpose Is the preservation of society. Work therefore has moral and legal implications. Work is a legitimate use of our mental and bodily powers for economic gain or profit 1 . Work is the use or application of our physical powers to accomplish certain tasks. It is the use because nobody can own another mans body, nor can anyone sell his body or any part of it, for purposes of material advantage or gain. . Work is the repose of obtaining economic gain for the power. It belongs to the essence of work that it can be compensated. The Meaning of Work in the Holy Bible From the biblical point of view, God is seen as the author of work and he also blessed and sanctioned work. Old Testament God did not Just create man, He was also the author of work. In Genesis chapter 1, He creates pattern for us to follow He created the world for SIX days and rested on the seventh day. The reason for this respite Is for man to appreciate the value and meaning of work. New Testament The meaning of work could be understood from the mystery of Gods reincarnation. When Christ became man, humanity was blessed and sanctified, including human work. Seen from this perspective, work therefore is not a drudgery, not even a curse, but an activity that has been sanctified, then it must also sanctify the worker. The Theological Meaning of Work According to SST. Thomas Aquinas SST. Thomas Aquinas enumerates four purposes of work In his treatise entitled Summary Theological 1 . It provides for ones day livelihood. 2. It prevents Idleness which Is the source of many evils. . It curbs the rebellious flesh. 4. It enables man to give alms from his material surplus. The Human Perspective of Work . Practice the Golden Rule. 2. Guard your mouth. 3. Stop the green Jokes. 4. Practice ethical behavior. 5. Learn to forgive. 6. Be generous. 7. Respect superiors and co-workers. 8. Be considerate. 9. Perform your work and fulfill your duties to the best of your ability. 10. B ea grateful person. 11. Do not bring the problems at your home to your workplace. (vice versa) 12. Be an inspiration to others. 13. Read the bible every day. 14. Develop a personal relationship with God. 5. Smile and enjoy work. (remember: work has been sanctified, it must also sanctify you) Basic Duties of Employers 1 . Respect the dignity of the worker 2. Appreciate their work. 3. Never treat them as a slave for making money. 4. Never assign them beyond their strength, do not employ them in work not suited to their age or gender. 5. Give them commensurate or fare wages. 6. Provide for their health and social recreation. 7. Provide them time for the practice of their religion. 8. Instruct them how to use their money wisely. 9. Instruct them to love their family. 10.

Never employ deceit nor violence in presenting a cause. 5. Never consult with agitators or men with evil principle. CHAPTER 15 Equal Employment Opportunities and Affirmation Action EQUAL JOB OPPORTUNITY- Is a labor policy that prohibits business from discriminating against otherwise-qualified people with disabilities. JOB on the basis of personal merit but on the basis of partiality or bias. AFFIRMATIVE ACTION Involves policies to increase opportunities for ethnic minorities by favoring them in hiring and promotion, college admissions, and the awarding of government entrants. What is employment discrimination? Employment discrimination is a form of discrimination based on race, sex, religion, national origin, physical disability, and age by employers. Earnings differentials or occupational differentiation is not in and of itself evidence of employment discrimination. Discrimination can be intended and involve disparate treatment of a group or be unintended, yet create disparate impact for a group. 179. What are the factors to consider? Soon and Palm-Angles (1997) think that it really depends on several factors, such as the following: Who his competitors are What abilities his competitors have How interviewers see him How he performed during the exams and interviews 180. Is it easy to detect discrimination in the workplace? The truth is that it is not easy to detect whether or not there is discrimination in the workplace. Spotting employment discrimination is a big headache because it is generally hard to know whether specific individuals were actually discriminated against. 181 . What are the elements of Job discrimination? It may be of help if we are to identify some elements or factors that somehow constitute Job discrimination (Velazquez, 1998), and I enumerate here as follows: 1) When a Judgment, decision, or treatment (not based on personal merit such as seniority, performance rating, or other qualifications) is intended against anyone of the workers and his/ her particular group (2) When a Judgment, decision, or treatment springs from prejudice or bias, from false stereotypes, or from other ways of unfair attitude aimed at a particular group to which the worker belongs (3) When a Judgment, decision, or treatment is disadvantageous, pejorative or simply harmful to the worker, perhaps costing his/ her Job, promotion, or pay raise 182. How do you know whether those elements apply to our earlier example? Most likely, racial discrimination was a shadow behind the promotion or a better pay if the following three elements are present: (1) Was the discussion of management to bypass the Filipino assistant manager in favor of the French assistant manager based on personal merits such as seniority, performance rating or other qualifications? Or the criterion to promote the French assistant manager has nothing to do with merits, qualifications, and credentials? (2) Did the decision spring from false stereotypes such as the French are more competent, aggressive, or trustworthy Han Filipinos, Asians in general, and other ethnic groups? The presence of this element may be hard to prove. (3) Was the decision disadvantageous to the Filipino assistant manager in terms of a promotion or a better pay? 183. Is there discrimination against women in the workplace? In the Philippine setting, it looks like there is still some kind of Job discrimination The major challenge women have to confront relates to the fact they are the ones who biologically bear children and carry most of the burden of rearing and caring for them. Employers are equally afraid they must provide childcare support by setting up a Hillsdale facility at or near the workplace and other unending benefits for women. Almost always, HER managers are inclined to distinguish between a career woman and a mother, with the latter usually discriminated against in favor of the former. 184. What are the stereotypes against women? Job recruitment and interviews are discriminatory if the recruiter or interviewer routinely disqualifies women by relying on sexual stereotypes. These stereotypes may include some presumptions: There are fields of occupation, which are traditionally suitable for women because of their sensitive, vulnerable, and fragile nature. There are types of work, which may not be fitting to women due to their biological condition like monthly period. The inability of women to cope up with certain Job requirements since their common gender personality and aptitude traits make them unsuitable for those Jobs. Such generalizations about women are not only biased or prejudicial but also UNTRUE. 185. What is the lesson learned from the 1997 film 6. 1. Jane? The movie 6. 1. Jane, starring Deem Moore, demonstrates the active presence of a determined woman in the toughest military facilities of the US Navy Seals. Veritably, mimes have changed. In the real world-not by pure chance, luck, or accident-women have become heads of state in Israel, Pakistan, India, Nicaragua, Ireland, Finland, Great Britain, New Zealand and other nations. 186. How is discrimination related to right to life ? It is unethical and socially irresponsible for any employer to dismiss or discharge an employee merely on account of his/her marital status. Hiring, firing, promotion, or demotion must be subject to an objective, unbiased and fair criteria. Workers ought to be treated equally on the basis of individual merit and not on the ground of sexual orientation or marital status. 187. What are ethical principles involved in Job discrimination? Discrimination in the workplace is wrong and socially irresponsible because of the following reasons: 1) Discrimination in hiring is a disservice in the long run. To hire the best and the smartest it is wiser to select somebody whose talents and personality traits quality him/her as the most competent for the Job. If you so hire and appoint someone on the basis of other criteria unrelated to competency, then subsequent Job performance necessarily declines and productivity goes down. Thats one pragmatic argument against employment Discrimination. 2) It is actually double Jeopardy. Both the object and the subject of discrimination turn out to be the loser. The company could have possibly hired the worker discriminated against, the one who might turn out to be the best and most suited for the Job. But because it was biased, the company did not pick up the best possible applicant, suffered a disadvantage and got no blessing. Ethics. To discriminate is not the right thing to do. Each person has a fundamental right to be treated as a free and thinking individual and all other individual including employers) have a correlative moral duty to treat him/her as such. 4)when business discriminates, it consciously or unconsciously affirms that one group is inferior or subordinate to another group, that people from the province are less qualified than city residents, or UP and La Sale graduates are better than CRU or PUP graduates, that women are less capable than men, that French employees are better that Filipinos. Such regarding stereotypes undermine the self-esteem of those groups against whom the stereotypes are directed and thereby violate their fundamental right to be treated as equals. Discriminatory practices are not consistent with ethical management which upholds that all are equal in essence and dignity and that all men and women have the same basic rights and duties. Everyone is created equal in essence and dignity, in spite of the race or color, religion, sex, party affiliation, or business connections (Velasquez, 1998). 188. What is the best practice of shell in terms of diversity standard? Creating an inclusive environment that elicits the very best from its employees is fundamental to shells success. Therefore, the oil company is committed to manage diversity as a radical business activity. It values the broad range of cultural and personal differences that exists in the company. The company is benchmarking CARS on diversity and inclusiveness. Shell dedicated to respect each employees need to balance work and personal demands, and provide equal opportunity for everyone to compete through well-understood and consistently applied employment and performance standards. Thus, the company provides means for employees to share, networking, learning, self-development and communication. Royal Dutch/shell group(2002) reports that shell companies across the globe promotes a culture in which all shell employees, contractors, and Joint ventures share his commitment for diversity. In order to underpin this commitment, every shell company must assure that it: Has a systemic approach to diversity management addressing each of the elements of the group Diversity Framework; Actively supports attraction, development, retention, and promotion of diverse talents; Promotes a workplace free from harassment and discrimination; Establish annual diversity plans, goals and targets for improvement; measures, appraises and reports business performance; Includes diversity performance in the appraisal and development plans of leaders ND employees; Provides safe and effective ways for employees to report observed behavioral inconsistencies with this standard. Chapter 16: Against Conceptualization Is Conceptualization Socially Responsible? What is labor conceptualization? Is the replacing of regular workers with temporary workers who receive lower wages with no or less benefits. These temporary workers are also known as sometimes called contractual, trainees, apprentices, helpers, casuals, piece raters, agency-hired, and project employees, among others. They do the work of regular workers for a specified and limited period of time, usually less than six months. The work they do is desirable and necessary for the companys survival, but they never become regular employees even if they get rehired repeatedly under new contracts. The general public is sounding the alarm on the steady growth of both unemployment and underemployment. The concrete situation of millions of sales ladies in our department stores and giant malls, some factory workers, house helpers, carpenters, gasoline boys, workers in the barber shops and parlors, whose jobs are permanently temporary, simply because they are contractual. They have no stable Jobs, no ASS, no medical insurance, no security of tenure?not to mention the 6 million Overseas Filipino Workers who are employed on a contract-to- contract basis, more than 70 percent of whom are domestic helpers and entertainers stationed in four corners of the globe. The new millennium, tagged by management guru Peter F. Trucker as the century of knowledge society, is witnessing the sudden increase of part-time Jobs even among our professionals. This is happening in spite of the fact that the Filipino labor force in general is globally recognized as technically proficient, highly educated, almost always over skilled, let alone our competitive advantage in the English language. Filipino workers are prioritize among Asians by many international companies. Is contractual labor part and parcel of the big economic landscape? Contractual labor is and has been there as part and parcel of the big economic picture?in agribusiness, sweatshops, construction, and retail business. Nevertheless, the fact that it has been with us for a long time does not make it correct. At any fast food chain you and your kids happen to drop by and eat, it is very probable that only a few of the uniformed crew (18-24 years old) who are on duty will become casual, probe, or regular employees. One thing is sure for those crew embers, the rest of them are out of work before the sixth-month deadline imposed by Labor Code. Even oversupplied nurses are now contractual laborers. From there, some have to renew their contracts while others have to look for another job, usually in another fasted or gasoline station or hospital, and the vicious cycle of conceptualization continues without ceasing. The conceptualization of labor is a business strategy or practice, validated to be cost effective. What could be the raisin d ©tree why Article 23 was included in the Universal Declaration of Human Rights that says, Everyone has the right to work, to free choice f employment, to Just and favorable conditions of work and to protection against unemployment? The basic foundation for full employment is the 1987 Philippine Constitution protecting the right to full employment in the following provision: Article 13, Section 3, The State shall afford full protection to labor, local and overseas, organized and unrealized, and promote full employment and equality of employment opportunities for all. From here, we can safely assume that both able and disabled bodies have the natural right to earn a living by a meaningful occupation, a Job worthy of the free and hinging person. This basic human right to work and earn a legitimate means of livelihood entails a solemn duty on the part of private business sector and the government to provide ample opportunities for adequate work and full employment. Jobs are not enough. It should be adequate and full?regardless of how beautifully some pundits explain various theories of underemployment. Why is it a choice between underemployment and unemployment? Underemployment refers to an employment situation that is insufficient in some important way for the worker, relative to a standard. Examples include holding a part-time Job despite desiring full-time work, and over qualification, where the employee has education, experience, or skills beyond the requirements of the Job. Unemployment (or Joblessness) occurs when people are without work and actively seeking work In the technical sense, conceptualization is a form of underemployment. The right to adequate work and full employment is essential to all men and women of legal age, as swimming is essential to a fish and flying to a bird (well, most birds). This basic right springs from our intrinsic nature to self-preservation and our innate obligation o support our family, both of which are in accordance with the divine plan. Although underemployment (conceptualization and part-time Jobs) continues to exist in many various ways, there are no reasons adequate enough to Justify it. The key principle is that full employment is a fundamental right of every citizen, which means the right to be protected from unemployment and underemployment is basic. The harsh reality, however, appears to contradict this idealism embodied in our In most cases, on the part of the Jobsharers, who are almost always breadwinners, it is a choice between Joblessness and underemployment, a quick option between anger and at-least-theres-hope-for-survival. Is conceptualization a scheme for profit minimization? Ever since the Philippines Jumped into the GATE-WTFO bandwagon, times have been especially difficult for labor. The name of the game is cheap labor. In order to attract foreign investors?aspiring to be competitive as they say with our Asian neighbors? we have to provide the cheapest labor possible. And this cheap labor comes through conceptualization of Jobs and services. It appears that conceptualization is a scheme that allows capitalists to replace their workforce with ease according to market demands. This translates to minimization of profits for the company, but for the laborers, this system denies them the security and benefits of a regular Job while being paid very low wages. Conceptualization has become the main form of labor in many Philippine businesses, a good reason why there are hardly any labor unions in the country or why most workers are not organized in the new millennium. Contractual workers cannot afford to Join unions because they are at the mercy of their employers. Many laws protecting workers protect only regular employment. Ethics and Professional Codes of Conduct The era of globalization has created a need for a specialized skills and knowledge. 1 . Skills is the ability to do something well. 2. Knowledge skill that acquire during your education and experience. The reason for the globalization is known as full automation. This situation bring the word profession, professional and professionalism exist in the corporate world. 1 . Profession a type of Job that requires a special education, training or skill. 2. Professional -relating to a Job that requires special education, training, or skill done or given by a person who works in a particular profession paid to participate in a port or activity 3. Professionalism the competence or skill expected of a professional. Members of profession are required by their association to follow their particular rules or guidelines known to be Professional codes of conduct. These guidelines prescribe responsibilities that members must adhere to and situations in which they must not involved. In some cases, members must be sanctioned for violation of the code. These sanction may include the following : Payment of a fine Payment of a cost of any investigation Reprimand Imposition of condition on membership Suspension from membership Sometimes ,the law silent or absent in some areas of our human conduct. The law does not say anything about this human conduct and its regulation. In the absence of law, some people tend to make their own professional codes of conduct. However, professional codes of conduct are limited only to some specific professions and cannot be entirely regulated and imposed to all while Ethics is universal and applicable to all.

A Quest of Realization essays

A Quest of Realization essays In the movie The Seventh Seal, Bergman portrays his main character, Antonius Block as a wanderer. Antonius journeys his way thorough the movie in search for an answer. He goes on a quest to find if God really does exist and if He does, why hasnt He shown himself and make some clear evidence of it. Antonius soon realizes that the answer he was looking for is a big disappointment in the end. It is not until Death is literally knocking at his front door does Antonius come to the conclusion that God will not help him conquer death, and man dies when he does because he does with no questions asked. Throughout the course of the movie, new experiences and knowledge cause Antonius to come to his ultimate conclusion that there is no God or hope; only pain and heartbreak. As Antonius and his squire Jon journey the land, they come across a girl named Tyan who helps the knight fins some truth to his quest to believe that there is no God. While Antonius, Jon and the others travel the land, they find a girl who has been accused for started the plague and befriending the devil himself. The consequence for this action; death by being burned at the stake. Thinking that perhaps this girl could help him out, Antonius takes the advantage of asking her some questions so perhaps she could help him find the knowledge which he is in search for. When he asks her if the accusations are true, she replies that yes, she truly has seen the devil and she has also slept with the devil and has the devil within her. Tyan then tells Antonius that he too is capable of seeing the devil. All he has to do is look deep into her eyes. When Antonius looks into her eyes, he does not see the devil. The only thing that he saw inside her was terror and fear. As Tyan is at the stake, she, along with Antonius himself, realize that after life, there is nothing. The emptiness in Tyans eyes said it all. Antonius realized this and felt more lost than he di...

Alice in Wonderland (2010) Movie Review Example | Topics and Well Written Essays - 750 words

Alice in Wonderland (2010) - Movie Review Example Tangled and highly dynamic plot creates a favorable medium for Tim Burton’s fantasy. ‘Alice in Wonderland’ combines literary traditions of English classics, surrealism, Burton’s fantastic style, and 3D animation. The animators strived to cover a broad target audience – little children, teenagers, youth, having-many-children families. As any high-quality commercial product it should meet requirements of the large audience. Besides, the film is the next lure for Johnny Depp admirers. As in his previous works, Tim Burton’s gothic and mystical style left its mark on the film. ‘Alice in Wonderland’ is built up on the opposition of the worlds of goodness and evil. Deck of cards (Red Queen, Stayne) embody the world of evil and chess – the world of goodness (White Queen, Alice, Mad Hatter, White Rabbit). The same concept of contrast was applied in ‘Corpse Bride’, where the main hero simultaneously lived in two worlds. Positive heroes struggle against cruelty, aggression and injustice of the Red Queen’s court. This is Burton’s extraordinary 3D world, full of contrasts, bright colors and absurdity. Excellent performance of actors completes the picture. For example, Helena Bonham Carter’s performance in the movie is outstanding, because all the scenes where she is present with her funny appearance with a big head and heart shaped lipstick, it seems hard for the spectators to concentrate somewhere else.

GOP Debates on 09.07.2011 and 10.18.2011 Essay Example | Topics and Well Written Essays - 1000 words

GOP Debates on 09.07.2011 and 10.18.2011 - Essay Example It was clear that the debate would be aggressive as Romney and Perry exchanged blows. Both candidates continuously challenged each other with allegations one every given opportunity. The debate was undoubtedly crucial as the economy has been lagging and Obama’s popularity has been diminishing. Throughout the debate, it seemed that Perry was confident and poise even with criticism that were alleged against him. His illustration of running a country with the same policies as Bush and Regan made him formidable against his opponents. Perry came out aggressive, attacking Romney often and early as he tried to gain leverage with the voters. Moreover, he continued to avoid the accusations that were made to him. It seemed as he did not finish strong at all, but did able to leave his impression. Perry and Romney’s clash was the focal point as Romney attempted to mimick the same strategies as McCain and Dole. It was evident that Romney wanted to gain leverage but failed to do so. After dodging the accusations from Paul, Romney counterattacked. Romney seemed to look defensive in his stand. It seems as if Perry will dynamically modify the GOP race. While Perry and Romney dominated the packed, Gingrich and Paul did make some impact. Gingrich seemed to be confident at times with his plan to increase employment but failed to gain any momentum as he was too focused on attacking the media. Similarly, Ron Paul offered a strong defensive stand against libertarianism, but failed to expand his argument as he continued to emphasize non-trivial matters such as vaccines for HPV, eliminating TSA agents and FMA. Furthermore, it seemed that Paul promised too much financial stability that seemed too good to be true at this point. It seemed as if Paul and Herman Cain were on the same playing field. Herman Cain good off to a good start as he insisted on reducing taxes but was shot down of the sexual allegations that continued to diminish his reputation. Rick Santorum and Jon Hu ntsman, both failed to solidify foundation. Rick Santorum was passionate but kept deterring from main issues as he kept using big words that were not comprehended by the public. Santorum failed to gain any ground like Cain, who was already having a hard time feuding against accusations that were made against him. Jon Huntsman, another Republican nominee, was clearly out of sync as he failed to build his repertoire in any manner. His futile attempts to build his reputation as a diplomat seemed to be quite interesting. The only female of the Republican party, Michele Bachmann, seemed to be a very interesting yet fanatic character as she proposed a universal $2.00 per gas gallon. Overall, the essence of this Republican debate symbolized the critical events for the upcoming elections. THE GOP DEBATE ON OCT 18th The GOP debate on October 18th was another testy affair as candidates continued to spar with each other on critical issues such as foreign policy, immigration, and tax plans. It seemed to be so feisty that New Gingrich, the Republican candidate, took a huge shot at Obama as he remarked, â€Å"Unlike President Obama, I’m glad to be in Las Vegas. It’s a great place to have a convention.† Similarly, Rick Perry did not wait for his chance to take shots at Herman Cain, criticizing him of his 9-9-9 plan as he stated, â€Å"

Comparing Structures of the Heart

Comparing Structures of the Heart This exercise was conducted so that the anatomical construction of the cardiac structures would be evident.There were no safety precautions necessary as all dissections were done on line as virtual dissections. Activity 1: Microscopic Anatomy of Cardiac Muscle Observations: Sketch and label your slide in the space provided. Include a description of the structures you observed on the slide. What are some unique structural features of cardiac muscle? Cardiac muscle is striated and uniquely structured to function in a muscle that is used approximately 70 times a minute, 24 hours a day, and 365 days a year for an average of 80 years. Cardiac muscle is branched, not linear like skeletal muscle. Cardiac muscle has alternating thick (myosin) and thin (actin) protein filaments which are the sliding filaments. These are the two primary proteins that build the cardiac fiber which is called a myofibril. When viewed under the microscope, also seen are the darker lines perpendicular to the muscle fiber which divide the cardiac muscle. These are the intercalated disks. These structures enable transmission of muscle contraction signals. The intercalated disk allows the rapid propagation of the muscle action potential which enables the myocardium to contract together and allows for ventricular synchrony. The heart must work continuously. That is why it has an abundance of mitochondria in the myocardium. In fact, approximately 50% of the myocardium is mitochondria. These structures are the cellular power generators for the cells. They enable constant aerobic respiration which supplies energy to the myocardial cell for constant function. What are intercalated discs and what do they do? The intercalated disks enable transmission of muscle contraction signals. The disks allow for the rapid propagation of the muscle action potential which enables the myocardium to contract together and allows for ventricular synchrony. Why does cardiac muscle have to be both elastic and strong? The human heart must be elastic as well as strong in order to meet the needs of the human body. The elasticity of the atria and ventricles is important in order to accommodate the preload that is essential to trigger the stretch of the myofibrils that is inherent in contractility and vital for cardiac output or the ejection of blood. When an individual participates in exercise and has a faster heart rate, the chambers must dilate (or stretch) to accommodate the returning volumes in order to meet the greater need for oxygen in the exercising muscles. As the heart returns to normal resting rates, these dilated chambers return to their normal size. Chronic chamber dilation (or cardiomyopathy) can be detrimental to the function of the heart and result in decreased pumping, loss of forward flow as well as heart failure. Contractility of the actin and myosin fiber is an inherent property of cardiac muscle. But strength of contractility is important to overcome afterload. Afterload is defined as the force that is needed to overcome aortic pressure for cardiac ejection of stroke volume. Afterload is increased in the presence of sustained diastolic hypertension. Over a period of years this continual increase in the work of the heart will lead to hypertrophy of the ventricular muscle and not only will strength of contraction be lost but increased oxygen consumption will be detrimental to the myocardium and may result in angina or infarction. D. Which of the three layers of the heart did the tissue used to make your slide originate from? The slide was made from the myocardium or muscle tissue. Activity 2: The Pulmonary and Systemic Circuits Draw a diagram showing pulmonary and systemic circulation. Color the deoxygenated side blue and the oxygenated side red. Use a regular pencil to draw arrows to indicate blood flow. Questions: Trace the flow of blood through the pulmonary and systemic circuits. Begin in the right atrium and end in the superior/inferior vena cava. Be sure to list every vessel, heart chamber, and heart valve the blood flows through. Blood flow through the heart begins with the returning deoxygenated systemic bolus into the right atrium. Passively it flows through the low pressure atrioventricular tricuspid valve into the right ventricle. As pressures equalize, the tricuspid valve closes. In the right ventricle, this bolus is pressurized isometrically and then ejected through the low pressure semilunar pulmonic valve into the right and left pulmonary arteries. The bolus then travels through the pulmonary arteries into the pulmonary arterioles and capillaries until it is in single file in the capillary at the alveolar-pulmonary basement membrane. At this point the red blood cell transverses the capillary lengthwise in order to present a greater surface area for oxygen and carbon dioxide exchange. Now the oxygenated red blood cell travels through the pulmonary capillary bed into the pulmonary venules and into the pulmonary veins. Through the pulmonary veins, of which there can be 3 to 5, the blood enters into the left atrium ( there are no valves in the pulmonary veins, unlike other veins, and the bolus of blood is pushed forward by the continual movement of blood from the right atrium and ventricle ) . Again passively the bolus of blood flows through the higher pressure mitral valve into the left ventricle. As the pressures again equalize, the mitral valve closes. As the bolus of blood, now known as left ventricular end diastolic volume or more correctly preload, is pressurized again isometrically, the pressure of the aorta (afterload) is exceeded and ejection occurs though the semilunar high pressure aortic valve and into the aorta. The oxygenated blood now travels through the aorta for dispersal to all the organs and tissues of the body for oxygenation and removal of the cellular waste product, carbon dioxide. From the aorta, blood travels into the smaller arteries, arterioles and eventually the various capillary beds. After the O2 and CO2 exchange occurs at the cellular level, the deoxygenated blood travels from the capillary beds into the venules, veins and eventually into the vena cava. The vena cava returns the deoxygenated blood into the right atrium via the inferior and superior vena cava vessels. And the process continues as long as the heart beats. Explain what you learned from the online human heart dissection. I must truthfully state that I did not gain any new information from this exercise. I have been an RN for almost 40 years and my primary area of practice is critical care. One of my areas of expertise is cardiology. I have been certified in critical care (CCRN) for 36 years and I am also cardiac medicine certified (CMC) by my national organization. However, it was interesting and a very nice review. Activity 3: Sheep Heart Dissection/Fetal Pig Comparison Questions: Compare the structure of the fetal pig and sheep heart. How are they similar? How are they different? Except for the differences in size, I did not note many differences between the sheep heart and the fetal pig heart. They are similar in that their construction is a 2 chambered atria and ventricle and there is similar vasculature. I did note that the fetal pig heart showed similar muscle mass of both the right and left ventricles. The left ventricle had not increased in myocardial muscle mass yet as the heart had not needed to be the sole source of power for perfusion. After birth, I believe that the left ventricle will increase in mass as seen in both the sheep heart and the human heart. Why is the heart referred to as a double pump? The human heart is referred to as a double pump because of the differences needed to handle systemic return and peripheral forward flow. The right heart is a lower pressure system and blood enters passively, driven by the left ventricular ejection force. This blood enters into the lower pressure pulmonary system, where pulmonary arterial systolic pressure is comparable to right ventricular systolic pressure. The left side of the heart is a much higher pressure system. As the blood leaves the left ventricle, it is at a much higher pressure due to the need to overcome the afterload of the aorta. (Systemic vascular resistance.) Because of this increased need, the left myocardium is considerably thicker than the right ventricle. Additionally, because of this increased muscle mass, during the sustained contraction phase (consistent with the ST segment in the electrical tracing), there is much higher oxygen consumption in the left ventricle. This predisposes the left ventricle to more cardiac issues such as angina, infarction, myopathies, hypertrophies and sudden death due to electrical disturbances. There are four valves in the heart. Name each valve, list its location and give its function. The four valves of the heart are the tricuspid, the pulmonic, the mitral and the aortic valve. The tricuspid valve is located between the right atria and right ventricle. It is a low pressure atrioventricular valve and its job is to prevent back flow or regurgitation of blood into the right ventricle during systole or contraction The pulmonic valve is a semilunar cusped valve located in the ostium of the trunk of the pulmonary artery which takes off from the right ventricle. When the right ventricle contracts and blood is pushed into the pulmonary artery, the pulmonic valve closes as the pressures are equalized. The cusp like structure helps to push blood forward. With the valve closed there should be no regurgitation from the pulmonary artery into the right ventricle, this time during diastole as the dilation of the ventricle creates a vacuum to enhance diastolic filling from the atrium. The mitral valve is a bicuspid or 2 leaflet atrioventricular valve. It is located between the left atrium and the left ventricle. As the left heart is a higher pressure system, the mitral valve must be able to withstand greater pressures. During the contraction of the left ventricle, closure of the mitral valve prevents regurgitation of blood from the ventricle into the left atrium. The mitral valve, as well as the tricuspid valve, is attached to the ventricular walls by chordae tendinea and papillary muscles. During infarctions of the left anterior ventricular wall, these structures can become ischemic and lead to mitral valve dysfunction, further complicating the infarction. The aortic valve is located at the root of the aorta at its junction with the left ventricle. It is a high pressure, cusped, semilunar valve that must withstand tremendous pressures during left ventricular ejection. Again, if the valve becomes incompetent, blood can flow back into the left ventricle during systole (ejection). This can lead to ventricular overload and pulmonary vascular congestion as well as forward perfusion issues. Both ostia of the coronary arteries are located at the aortic valve near the sinuses of Valsalva. If ventricular ejection is decreased either through poor contractility or incompetent aortic valve, coronary artery perfusion can be affected. Compare the left and right sides of the dissected heart. What differences do you see? When the dissected human heart is laid flat, both atria and ventricles can be seen. In this view, it is very obvious how much more muscular the left ventricle and even the left atrium is, when compared to the right side of the heat. The interventricular septum bows slightly into the right ventricle. The left ventricular chamber is larger in size and the left atrium is also larger In the right and left ventricles you can see the papillary muscles and chordae tendinea that attach the tricuspid and mitral valves to the interventricular wall. In the right ventricle there are trabeculae, light finger like projections that are not readily noted in the left ventricle. Compare and contrast the functions of the atria and the ventricles. Both atria are receiving chambers, with the left larger and more muscular than the right. The right atrium receives systemic, deoxygenated blood from the superior and the inferior vena cava and deoxygenated cardiac blood from the coronary sinus. The left atrium receives oxygenated blood from the pulmonary circuit via the multiple pulmonary veins in the left lateral wall. The right atrium is also the home of the heartà ¢Ã¢â€š ¬Ã¢â€ž ¢s electrical system. The sino-atrial node (SA node) is located in the roof of the right atrium and is the primary pacemaker of the heart maintaining an inherent rhythm and rate of between 60 and 100 beats per minute. In the floor of the right atrium, near the junction of the atrium and the interventricular muscular septum is the atrioventricular node. The AV node or junction is a backup pacemaker of the heart, designed to come in as an escape mechanism if the SA node fails as can happen in cardiac disease or sometimes drug induced mechanisms. The junctio n is designed to only run the heart when it does not receive the SA nodal signal and so its intrinsic rate is 40 to 60. There is an automatic pause built in between the electrical signal of the SA node and the firing of the AV node and this is known as the AV interval. This slight pause is sufficient to allow the final filling of the ventricles before systole. The waveform generated with SA nodal firing causes the right atrium to contract and push the remaining blood into the right ventricle. This contribution to ventricular filling is known as atrial kick and can be extremely important to individuals with limited cardiac reserve. There are conduction pathways running through the right atrium and over to the left atrium but the atrium does not have any electrical nodes similar to the right atrium. In abnormal rhythms such as atrial fibrillation and atrial flutter, there are sometimes aberrant pathways in the left atrium that contribute to these dysrhythmias. They are occasionally treated with ablation therapy and scarring of the atrial wall. Both ventricles are pumping chambers but the left is the more massive and more vital of the two. The right chamber receives the preload initially and if it is diseased or injured, its dysfunction can severely impact the left sided filling and cardiac output. The left ventricle is 2 to 3 times more muscular that the right and even thought the ventricles work in harmony, the leftà ¢Ã¢â€š ¬Ã¢â€ž ¢s job is ejection and perfusion to the organs and tissues. The predominance of the coronary artery system is located on the left ventricle and the majority of coronary artery disease involves the left ventricle. Where is the myocardium located? The myocardium is the inner muscular layer of the heart, located between the epicardium and the endocardium. The epicardium is the outermost layer and is formed by the pericardium folding back onto itself at the aorta. Inflammation of this lining can cause pericarditis. The endocardium is the epithelial lining of the inside of the heart and includes all the structures internally. The endocardium also has an endocrine function, secreting endocardin which helps to sustain contraction. Infarctions can involve the endocardium and previously were known as subendocardial infarctions but are now call non-stemis. (Non ST segment elevation myocardial infarctions.) Additionally, bacteria from peripherally inserted central lines or IV drug abuse or even dental disease can cause infections of the endocardium called endocarditis. The myocardium is the muscle mass that is involved in stretch and contraction. When there is a disruption of oxygen to an area of myocardium, it is referred to as a myocardial infarction (Stemi) Death of the tissue with subsequent ventricular dysfunction can result if oxygenation is not restored. How does the heart supply blood to its own cells? The heart needs a continuous and rich source of oxygenated blood. None of the blood that is pumped through the left chambers oxygenates the heart. The hearts source of oxygen comes from the coronary artery system. These vessels lay on the epicardium of the heart and through collaterals and perforators supply the myocardium with oxygen rich blood. The left coronary artery arises at the left Sinus of Valsalva on the aortic valve. It travels a short distance across the left atrium behind the pulmonary artery, which protects it from any external trauma, caudally towards the left ventricle and is known as the left main. Any significant disruption of flow at this level through stenosis or thrombus can cause sudden cardiac death. As the left main emerges from behind the pulmonary artery, it becomes known as the left anterior descending coronary artery (LAD). This artery travels from the atrium to the apex of the left ventricle, giving off significant branches and lies in the interventricular sulcus directly overlying the ventricular septum. When you look at the human heart and notice the heavy streak of fat running across the anterior wall of the left ventricle, you are looking at the protective covering of fat for the LAD as it lies in the interventricular sulcus. When the left main changes to the LAD, there is another branch given off that runs circumferentially between the left ventricle and the left atrium. This is known as the Circumflex and also lies in a groove known as the atrioventricular groove and is protected also by a fat pad. On occasion there is a 3rd branching that arises at this area known as the Ramus or Intermediate branch. Arising from the LAD are diagonals that cross the anterior surface of the left ventricle from the IV sulcus to the left lateral aspect of the left ventricle. The LAD also gives rise to a group of vessels known as septal perforators that perforate the anterior aspect of the muscular septum. The LAD crosses over the apex and turns upward for a short distance on the inferior aspect of the left ventricle. The Circumflex travels around the left ventricle and terminates on the inferior aspect of the left ventricle not far from the right ventricle in branches referred to as the muscular branches. As the Circumflex travels around the heart, there are branches that arise and travel caudally and laterally across the left ventricle. These 3 branches are referred to as the obtuse marginals. The Right Coronary Artery (RCA) arises of the right Sinus of Valsalva on the right side of the aorta. The RCA lies in the same atrioventricular sulcus that the Circumflex lies in as it travels between the right atrium and the right ventricle. When the RCA reaches the division between the anterior aspect of the right ventricle and the inferior aspect of the left ventricle, there is a large branch that comes off the RCA and travels laterally towards the LAD. This is referred to as the Acute Marginal branch of the RCA and feeds the right ventricle. Near the ostium of the RCA, there is a small lateral branch that is important for collateral feed to the LAD, known as the conus branch. As the RCA traverses the right ventricle branches known as muscular branches supply additional blood to the right ventricle. Having turned and been protected behind the inferior vena cava for a short distance, the RCA is now traveling on the inferior wall of the left ventricle. When it reaches the point where it would be over the interventricular septum, it makes a 90 degree turn and heads towards the apex of the left ventricle. At this time it is now referred to as the Posterior Descending Coronary Artery of the Right Coronary Artery (PDA). There is a mirror sulcus here called the posterior IV sulcus to protect the PDA. Just like on the LAD, the PDA gives off septal perforators that feed the posterior portion of the interventricular septum. The electrical system of the heart is feed predominately by the RCA as 60% of the time the SA Nodal artery arises off the PDA near this 90% turn and is a perforator type of artery. The AV Nodal artery, as a perforator, arises from the PDA directly at this angle, which is known as the Crux. Collaterals exist from birth and are widespread across the anterior surface of the left ventricle as well as the inferior surface. As we age ,they begin to develop and gain importance for cardiac blood flow when the other major coronary vessels develop atherosclerotic disease and stenosis. Coronary blood flow is on the supply and demand system. When another organ has an increased need for oxygen, (for instance, the colon) the heart rate increases to meet that demand. In the heart, however, the supply is meet internally through the perforators and smaller capillaries that run a small distance into the myocardium. The best filling of the perforators and capillaries is during diastole or rest. During systole, they are compacted by the muscles in which they lie. As the coronaries receive flow both during systole and passively during diastole, it is to the hearts advantage to not be tachycardia.

Weber in Singapore :: essays research papers

Imagine that Max Weber has been resurrected and is on a visit to Singapore. How would he interpret the various facets of Singapore society in relation to his theories and prognosis about the future of modern society? As we begin the twenty-first century, there is a growing recognition that Max Weber is our foremost social theorist of the condition of modernity. His pre-eminence stems from the scope, the depth, and the intensity, which he brought to this project. In short, Weber sought to explain the place of the modern individual in the world. Behind this deceptively simple foundation, lay a gigantic enterprise. Precisely so then, the beginning of this essay is devoted to underlining and illustrating the principal themes of Weber’s sociological investigations, especially those that would be used in interpreting the various facets of Singapore society. Next, this essay attempts to show how a resurrected Weber would interpret the various facets of Singapore society in relation to his theories and prognosis about the future of modern society. The concluding part offers criticisms, if any, and asks the importance of Weber in this modern age. Weber, it is often said, conceived of sociology as a comprehensive science of social action. As such, Weber distinguishes between four major types of social action. In zweckrational action, or action in relation to a goal, the individual rationally assesses the means to attain a particular goal. An engineer who builds a bridge as the most efficient way to cross a river often exemplifies it in the literature. A more relevant example would be the modern goal of material sought after by many young people today. Many recognize that the most efficient way to attain that success is through higher education, and so they flock to the universities in order to get a good job. Wertrational action, or rational action in relation to a value, is characterized by striving for a goal which in itself may not be rational, but which is pursued through rational means. The traditional example would be the brave captain who goes down with his ship. More relevant then is a person who attends the university because he or she values the life of the mind – a value that was instilled in them by parents, previous teachers, or chance encounter. Affective action is anchored in the emotional state of the individual rather than in the rational weighing of means and ends.

Differentiate Between Hazard and a Risk Essay

* Differentiate between hazard and a risk. Hazard is anything that causes injury, disease, or death to humans, or damage to personal or public property, or deterioration or destruction of environmental components. Risk is suffering injury disease, death, or some other loss as a result of exposure to a hazard. (Boorse) * What risks from Figure 17-16 and Table 17-3 surprise you and why do they surprise you? In figure 17-3 the aids rate is what surprised me I didn’t think it would be that low. If anything I thought it would be at the top of the list, but I also thought that alcohol us would be higher than that since it is some many people that use alcohol. (Boorse) * Differentiate between hazard and outrage? Give an example of a low hazard risk but a high outrage risk. A hazard is a chance of being injured or harmed and outrage is an act of extreme violence or viciousness. Example: You see a person crossing a highway full of speeding traffic coming both ways and are filled with hesitations. This is because of perceived risk to his/her life because of an incoming traffic at a high speed. But the man/women themself perceives no risk as he feels he is in control of the situation and will easily cross the highway before the cars arrives. The hazard to the life of the person remains the same but you are outraged more than the person and this is why you feel a greater risk than the person himself. This is a concept that explains why some risks are felt greater than others.
