Gospel Interpretation Project - Research Paper Example During Lazarus time, the dead were buried immediately after their death. This was because there were no preservatives of the dead body and burial had to take pace immediately so that the body did not decompose and become a bother to the people. Moreover, there were burial rites that needed to be observed. For example, in the case of Lazarus, he was wrapped with white clothing before he was buried according to the Jewish culture. Similar to many other cultures, people went to mourn with the family of the deceased. This explains why there was a crowd surrounding the home ground of Lazarus that Jesus found when he went to visit four days after his death. The people were aware that the body underwent decomposition after burial because the sisters to Lazarus indicated to Jesus that they were afraid that he was rotting and smelling already. Moreover, the people exhibited fear for the dead as they were not aware of the real condition of the dead. This explains why they were shocked when the y were shocked when he was resurrected (Harris 403). Prior to the event of resurrecting Lazarus, the Jews had threatened to stone Jesus. Therefore, the disciples were against the idea of Jesus joining any crowd that comprised of the Jews. However, Jesus indicated that it was during the day and he had twelve hours to complete his daily activities. It was at this point that Jesus made the disciples aware that Lazarus had died. However, at first he said it figuratively giving the disciples the impression that he was just asleep. After realizing that the disciples has not grasped the meaning f his words, he said it clear that Lazarus had died. However, he mentioned that it was a good thing that he had not been there during his death because this could present a good opportunity for them to believe. With this, Jesus was referring to the event making people believe that he was the son of God (V., C n.p). On

India is the most hierarchical society

India is the most hierarchical society BRIEF: India is the most hierarchical society in the world and this, obviously, has an impact on its management style. It is imperative that there is a boss and that the manager acts like a boss. The position of manager demands a certain amount of role-playing from the boss and a certain amount of deferential behaviour from his subordinates. The boss is definitely not expected to perform any seemingly menial tasks such as making coffee for everybody or moving chairs in a meeting room! Anglo-Saxon concepts of egalitarianism where the boss is the primus inter pares are virtually incomprehensible in a society still dominated by the historical conventions of the caste system. Therefore, the boss is expected to give explicit instructions which will be followed even if everybody knows that the instruction is incorrect. Managing people in India requires a level of micro-management which many western business people feel very uncomfortable with but, which is likely to bring the best results. Indian management is paternalistic and is characterized by: Patronage Families feelings Sense of security in staff Obedience to authority Personality cult Personality based delegation Aversions of the staff to the leaders who are outsiders Ascent on short rather than long term planning Restricted sharing of information Gulf between personnel policies and practices Traditional Indian management: Management practices:- Traditional Indian management Employee requirements- family relation and caste of employee is considered Leadership style- leaders display a high level of personal involvement with their subordinates. Motivational aspects and rewards- work is viewed as a means to an end i.e for sake of satisfying family needs. Human resource management practices- nepotism and caste consideration affect selection and compensation. Training is less emphasized. TYPES OF MANAGEMENT SYLE IN INDIA- 1) Conservative style: Integrating ideology- old is gold, change carefully Performance control- through traditions, conventions, precedents Coordination- hierarchical Staff motivation- financial security, psychological safety 2) Entrepreneurial style: Intergrating ideology- no risk no gain, pioneer, innovative, revolutionize Performance control- through shared vision of corporate team Coordination- hierarchical Staff motivation- through charisma of the person at top 3) Professional style: Intergrating ideology- scientific, rational approach to management Performance control- through norms of professionalism and other tools of management Coordination- variety of mechanism like hierarchy, committee planning Staff motivation- formalized menu of progressive, productive and quality oriented incentive. 4) Bureaucratic style: Orderly management, clear accountability Through rules and regulation Hierarchical, standard operating procedures Job clarity, steady promotion on basis of seniority 5) Organic style: Flexibility Through peer pressure, personal commitment Team work, mutual feedback, intensive lateral as well as vertical communication Job variety and richness 6) Authoritarian style: Obedience, organizational patriolism Through fear of punishment Hierarchical Patriotic feel and fear of punishment 7) Participative style: Relatively powerless decision making Through collective assessment on jointly agreed criteria of evaluation Through representative committee Feeling of participating in decision making 8) Intuitive style: Experience and common sense Thumb rule Hierarchical, also by informal norms No need for formal qualification 9) Familial style: One big happy family Through relationship of bosses Through personalities Feeling of being a part of family 10) Altruistic style: Its a means to social and spiritual end Through sense of mission or pursuit of great ideal Hierarchical, shared ideal or social commitment Opportunity to control something noble and meaningful Being a Manager in India To ensure successful cross cultural management in India, you need be aware of the strict protocols and rituals that exist. The official caste system may be illegal, but a strong hierarchical structure, based upon job title, still exists in business. The Role of a Manager In India managers may take a somewhat paternalistic attitude to their employees. They may demonstrate a concern for employees that goes beyond the workplace. This may include involvement in their family, housing, health, and other practical life issues. It is the supervisors job to regularly check on the work of a subordinate and to provide regular constructive feedback. This may include monitoring work quality and the timing of its completion. Approach to Change Indias intercultural adaptability and readiness for change is developing all the time. India is seen to have a medium tolerance for change and risk. It is important for innovations to have a track record or history noting the benefits if they are to be accepted and implemented. Failure in India causes a long-term loss of confidence by the individual as well as by others. Because of this attitude, intercultural sensitivity is going to be required, especially when conducting group meetings and discussing contributions made my participating individuals. Approach to Time and Priorities Indians are generally quite careful about time guidelines in business situations where schedules and deadlines are regarded seriously. In addition, however, Indian society is concerned with relationships so there may be instances where there is some flexibility to strict standards of adhering to schedules. When working with people from India, its advisable to reinforce the importance of the agreed-upon deadlines and how that may affect the rest of the organization. Successful cross cultural management will depend on the individuals ability to meet deadlines. Global and intercultural expansion means that some managers may have a greater appreciation of the need to enforce timescales and as such, agreed deadlines are more likely to be met. Decision Making The culture in India is very relationship and group-oriented, so a strong emphasis is placed on maintaining harmony and proper lines of authority in the workplace. Some Indians, however, are extremely direct, in which case you can deal with them in the same way. The manager makes decisions and accepts responsibility for work performed by subordinates. The middle manager may consult with subordinates before reaching a decision, although it is more likely that he will confer with trusted advisors or relatives. To ensure successful cross cultural management, you will need to bear in mind the importance of people in the office maintaining the proper behavior relative to their position. For instance, it would be inappropriate for a manager to make copies or move a piece of furniture because these are tasks that lower level people do. To engage in behavior beneath you would lower your esteem in the office. Boss or Team Player? If you are working in India, it is important to remember that honor and reputation play an important role. The risk becomes amplified in a team or collaborative setting. When meeting together and moderating ideas, intercultural sensitivity is necessary. It is important to qualify ideas that are raised in a gentle manner, protecting the reputation of those bringing up ideas, so no one is shamed. Communication and Negotiation Styles Cross cultural management will be more effective if you understand the importance of personal relationships. They are crucial to conducting business and are based on respect and trust. It takes time to develop a comfortable working relationship and you will need patience and perseverance. Indians are non-confrontational. It is rare for them to overtly disagree, although this is beginning to change in the managerial ranks. Decisions are reached by the person with the most authority but reaching that decision can be a slow process. Never appear over legalistic in negotiations; in general Indians do not trust the legal system and someones word is sufficient to reach an agreement. Successful negotiations may be celebrated over a meal.

Dreams Essay -- Essays Papers

Dreams Are dreams just the interpretation of the human unconcious mind? Do the dreams humans have represent unfulfilled wishes in there unconcious mind? Are feelings of de ja vue just those unconcious thoughts coming out in dreams and as such being thought of as all ready living that specific moment? All good questions that have plauged pyschologist since the age of Freud. Dreams have been seen in different ways by many different people. Some say that there are signs in dreams that point toward things that my happen in life such as omens. Other psychologist such as Freud say that dreams are just representations of our uncoucious minds at work. The world renowned psycologist also goes on to say, "Dreams are just unfulfilled wishes in our minds that come out in our dreams also known as our inhibitions (Freud 12). Dreams are so vast and come in so many forms, but the more they are studied they all point to Freuds view on the uncocious mind just trying to get out. Dreams occur when a person is just barely sleeping. Thier are five stages to sleep, the first being fully awake, the second stage which is barely asleep is where the dreams occur. At this stage in sleep people have what is called REM. REM stands for Rapid Eye Movement which means the eyes are moving at a fast pace. When observed on an electrode machine the subject has a lot of alpha movement in the brain(Lefton 123). Alpha waves represent a large firing of nuerons in the brain. This indicates that thoughts are being processed. Durring the last stage of sleep the person shows delta waves occupy the movement in the brain(Lefton 123). Delta waves are long drawn out waves with a slow increase and a slow decrease in the peak. This means that the brain is only conducting i... ...nclusions out of. The first dream dealt with the want to win a championship in soccer. The conclusions that I drew from the dream was that she was a motivated person who plays soccer, but having never won a state championship caused her do have the dream to fulfill her need to win a championship. However the second dream dealt with marriage. This dream was a little harder to put a finger on. The dream vary vivid and even included a few descriptions of people there. To me the dream was just easing her desire to get married at this point in life. This was an unconcious wish she had in her mind. When I asked her about marriage she replied, "I havent talked about it with any one but a couple of days ago I was thinking about it." Ozimok then went on to say" I cant believe how accurate the dream was in comparison to what I was thinking about only a few days ago (Ozimok)."

Achilles vs Hector Essay

In the story the Iliad, there are two main characters Achilles and Hector, who both are incredible warriors. Achilles is the leader of the Myrmidon soldiers, and he fights for the Greeks. Hector is the son of Kind Priam and he fights for the Trojans. Both of these characters are said to be the strongest and greatest warriors of each of their armies. Both Achilles and Hector have many different heroic characteristics that are the similar and that are very diverse. Achilles and Hector both share a similar glory of war and that love is a driving force and both of them have different views that set them apart which are military glory over family life and both of their overall hero characteristics which differ significantly. The differences between Achilles and Hector are very unique in the since that Achilles is basically the exact opposite of Hector. Hector believes that family comes first, after each battle he will come home and spend time with his wife and children instead of getting congratulated by his people. Achilles only cares about gaining glory that will last forever, since he knows that he will live a short life by continuing with his actions. But he finally chooses to live a short life so that his name will be remembered forever. When Achilles loses Briseis, he chooses not to fight with the Greeks even though this war is incredibly important to his people of Phthia and Greece. Achilles shows absolutely no support for Greece and doesn’t care about whether they win this war or not. Achilles begins to act very immature in the since that his fellow Greeks are dying and his soldiers around him want to fight but he chooses not to fight. When Petroclus dies, Achilles is full of absolute rage wanting retaliation for losing him. Achilles goes to Troy to fight Hector, and not only does Achilles kill Hector but he defiles and insults all of Troy by taking Hectors body and dragging his body back with him and leaving it to rot on the beach. Achilles is a very egoistic arrogant person who is only concerned with things that will benefit him and by killing Hector the way he did shows absolute disrespect. Achilles says to Hector before he dies, â€Å"My fury would drive me now to hack your flesh away and eat you raw-such agonies you have caused me† (409-411). This proves that Achilles was so mad that he believed the only way to kill him was the way he did. Furthermore, the similarities between Achilles and Hector are their strength and the fact that both of them are incredible warriors. Achilles is half god and half human which give him his extraordinary strength. Both of them possess a bravery that only exists in true heroes. Achilles and Hector are natural born leaders who all of their soldiers would happily end their life to save their leaders. Hector has an inconceivable amount of love for his country. He is willing to end his life to save the people of Troy. Hector knows that this war was started by his younger brother Paris’ juvenile decision to take Helen from Agamenmon. But instead of scolding his brother, Hector encourages him to fight for his country and his new wife. Hector says to Paris, â€Å"Look, your people dying around the city, the steep walls, dying in arms-and all for you† (251-253). Hector loves Paris because he is his brother and wants to help him let their people know that their prince is willing to fight with them. Throughout the Illiad both Achilles and Hector show that they are both natural born leaders and warriors. They both believe that glory in war and love is a driving force. Also both Achilles and Hector have many differences but mostly are shown in the fact that military glory is more important to Achilles than Hector’s strong family life.

Just when you thought it was safe to take final exams . . . vindictive multi-dimensional being reaches down (up? over? through? ) to Earth and pulls you out of the universe. You are thrown back into the universe at a place of this being's choosing, and she permits you to leave only after you have identified your surroundings. You are subject to several of these tests. Through a scientifically unexplainable miracle, you are able to survive in every one of the places you are tested. (Le st you become too comfortable, however, you certainly are able to feel any associated pain due to high temperature, pressure, gravity, etc. In each case described below, identify your surroundings. In some cases, the surroundings described may exist only during eras of the universe (past or future) other than our own time; in those cases, you should identify both the place and the time where you are located. 5) It sure is bright everywhere; you've been able to travel around a bit, and it's clear that you are not in a star.

7 Hardest College Classes

7 Hardest College Classes We’ve drudged through tons of online forums, social media networks, college websites and Google results to bring you the 7 hardest paths of knowledge the modern educational system has to offer. If you’re looking to tie your brain in a knot then you’ve come to the right place. We’re going to start with #7 and then work our way down to #1, and yes you guessed it, it has to do with math. #1: Rocket Science This is really more of a category than a class. The brainy genre encompasses many difficult math, physics and engineering courses that make the masses cringe. At the end of the day however, thanks to private space companies like Virgin Galactic, SpaceX and Blue Origin this subject is about to go mainstream. In a small matter of years we’ll be mining asteroids, colonizing Mars and building fleets of rockets for an emerging 21st century industry! The only reason Rocket Science places 7th on the list is because it’s still a fringe subject. The masses don’t really know if a new space age is about to begin or not. A tiny percentage of students are studying to become astronauts or rocket engineers right now but that’s probably going to change. #2: Beam Me Up: Quantum Mechanics/Physics Speaking of which†¦by the year 2050 this may start being taught in elementary schools, but until then this class is a real butt-kicker. Prepare to get really familiar with Einstein and the men and women who are advancing his theories and philosophies. Watch out, because it can get pretty abstract pretty fast. Prepare to have both hemispheres of your brain recruited to the umph-degree. #3: Let’s Get Metaphysical This isn’t PHIL 101 folks. We’re talking much deeper down the epistemological rabbit hole. The goal? To basically try understand the true nature of causation†¦to grapple with the differences between the subjective and objective universe/experience. Only those who seek the most profound of intellectual challenges dare take advanced Metaphysics. #4: Advanced Thermodynamics Most people think of weight loss these days when they hear the word thermodynamics. You know, â€Å"More energy out vs. calories in means you’ll get thinner!† It’s a bit more complicated than that. Rumor has it that Purdue University sports the hardest engineering courses in the land. In reality, studying the transference of heat on our plane is hard just about anywhere. Engineering is rough stuff, but it’s worth it! If you can handle it and keep your GPA high, you’re looking at potentially big $$$ upon graduation (or after internships). And, international appeal. Good engineers are in short supply everywhere but China and India pretty much. #5: Sigh†¦Economics Judging by the performance of central banks and Wall Street, current economic theory isn’t panning out so well (Keynesian). Maybe more people should study advanced economics? Well, over at Harvard (where many of our economic leaders study) Economics 1126 or the â€Å"Quantitative Methods in Economics† is a real challenge. If you choose to become an economist, please do a better job! Since when did it begin making sense to live in a debt=wealth world? So far it looks like mainstream economic theories of today are failing, mainly because they can’t adapt to the speed of technological innovation. Those who pass this class with flying colors are probably going to work in a think tank somewhere but collect a sizeable paycheck. #6: Organic Chemistry: The Doctor Destroyer Tons of people who believe they’re destined to be doctors one day see their dreams dashed and diverted by Organic Chemistry. For undergraduates, this is where you have to really take coffee and the library seriously. It’s often considered in hushed tones and whispers to be among the most difficult classes before you begin your post-graduate studies. Then of course we can talk about advanced physiology and anatomy classes as well, which are brutal. #7: Math Yep, just math in general. For many students algebra 101 feels like Organic Chemistry or Quantum Mechanics. It’s hard! Especially for the super-creative types that would rather write, paint and create than write out pages of equations for the purpose of†¦? So, what’s the hardest math class? That question was asked over at College Confidential and here’s some classes students talked about at length. Linear Algebra Complex Analysis Advanced Engineering Math Partial Differential Equations The Study of Algorithms The list goes on and on from there. That rabbit hole just keeps going and going like the Energizer Bunny created it. But there you have it ladies and gentlemen. Feel like conquering the highest and hardest levels of human knowledge. Now you know which classes to take. But let’s hear it, what do you think are the hardest classes at your college?

The International Intervention in Kosova essays

The International Intervention in Kosova essays The international Intervention in Kosova The break-up of Yugoslavia in the 1990s saw the creation of new independent states out of the republics that comprised it. Even though Kosova was one of the constituent units of the Yugoslav Federation, albeit not a republic, the international community refused to recognize it as a sovereign country. However, the recognition of other former Yugoslav republics such as Slovenia, Croatia and Bosnia as sovereign states by the international community did not prevent the ensuing war that claimed the lives of thousands of people on all sides. All international norms and conventions were suddenly violated as if they did not exist at all. The Wilsonian vision for the right to national self-determination was crumbling in a most ruthless way. This was also the case in Kosova where Serbia had established an oppressive and apartheid-like rule resulting in gross human rights violation that in turn led to an international NATO-led military intervention. My approach in favor of the international intervention in Kosova is very much shaped by the liberal theory in particular the liberal institutionalism. It is more than clear that Serbia was not observing international human rights conventions and treaties that it had agreed to. This was an open challenge to the new world order proclaimed by President Bush in the case of the international intervention against Iraq in 1991 arguing that the war was about more than a small country, it was about a big idea of a new world order with peaceful settlement of disputes, new world order against aggression, reduced and controlled arsenals and just treatment of all peoples. These values were clearly infringed in Kosova by Serbia. The conflict that erupted in Kosova in 1999 between the Kosova Liberation Army, the armed Albanian guerilla force, and Serb and Yugoslav security forces posed a great threat to international peace and security. There was also an imminent ri ...

Top 12 Creative Writing College Programs †Pro-Academic-Writers.com

Top 12 Creative Writing College Programs It may be too difficult to choose a dedicated creative writing program at the institution of your dreams. Another thing you should care about is how to pass the admissions process. Anyway, there are always some world-known alternatives that attract most of the students. Our team has researched several options in the field of creative writing colleges and corresponding programs to come up with this list of the top demanded colleges for creative writing in the USA. How Did We Choose? College rankings do not always reflect the reality. US News rating might be the most accurate, but you still have to rely on the obvious information you find about each creative college of your interest. We have prepared our own list based on the feedback of thousands of students as well as some other crucial factors. Mind not just what the rankings are, but how they are defined. Our top list will assist in your personal investigation. While observing, don’t forget to take notes which might be useful for your further admissions essay. In case you’re having some troubles with creative or academic writing, contact online writing help website to get a winning personal statement. First of all, it is important to understand which criteria I have used to name the best colleges in the field of creative writing. My first stage was to narrow down my search results by leaving only those institutions that proposed a particular creative writing major degree. In case you are sure in the competence of some schools which are not on the list, it may mean they only offer minors. While ranking those schools, we considered 5 basic factors: MFA Ranking  - This point stands for the level of local personnel proficiency and the number of smart students specific college attracts. We have looked through professors’ qualifications to choose the best places in terms of teaching. It was also noticed that colleges with powerful MFA programs tend to possess perfect alumni networks and internship options. At the same time, one has to realize that a lot of colleges with excellent undergraduate programs lack MFAs. Overall Creative College Reputation  - You still have to understand that the majority of your future classes will be in other areas than creative writing. Thus, we have evaluated the level of teaching other subjects such as English and Literature as well. Extracurricular Opportunities  - Another benefit of obtaining major  in creative writing is that it can lead to various creative writing opportunities after class, meaning part-time job and other activities. That is why our team has taken into account such features as internship programs, author readings, and literary magazines offered by the explored college. Learning Diversity - We have awarded extra points to each creative college with a large range of professional fields and interesting additional classes.   Alumni/Prestige  - We can say that deciding on this criterion is a rather subjective process, but we tried to do our best. We have searched for the famous writers released by the particular institutions. The product of any university is its graduates, so they have to be evaluated in order to assess the quality of local teaching. Possessing a brand name degree can be useful in many life situations. Top Preferred Creative Writing Schools Now it’s time to look at the list itself. It is not that easy to locate these wonderful creative colleges objectively, so we would say that it is simply the list of the best schools, not just another rating. While those placed on the first five places are simply amazing, the rest might be called super good. So, don’t take the numbering close to your heart.   #1: Northwestern University Northwestern's undergrad creative writing program  has conquered the hearts of many students as it is run by acclaimed tutors and graduates who became word-known authors (i.e., Veronica Roth with her â€Å"Divergent†). The University suggests that students get involved in such activities as running literary journal, interning at a publication, or submitting to the Department of English's yearly creative writing competition.   #2: Columbia University The institution offers two great programs: the one in creative writing and the one in journalism. Being located in NYC, students have an opportunity to try their best in local publishing houses and literary journals. #3: University of Iowa University of Iowa's  Graduate Writer’s Workshop is what makes this place absolutely special. It is called the most wanted MFA program in the US. Famous writers and established professors allow choosing from a large list of subjects. University’s literary community will provide you with any book or manual you need for free. #4: Emory  University If you have a desire to study creative writing along with the most professional authors and scholars, Emory  is right for you. Except for the regular classes, each student has a chance to visit questions-answers face-to-face sessions with the award-winning writers and journalists. You will be able to work closely with a personal counselor to complete an honors project. #5: Oberlin College Oberlin  is actually a pretty small liberal arts school in Ohio. Lena Dunham, who attends the school regularly to speak to the students, was among the local alums. Students can pursue writing in the surrounding city. #6: Hamilton College One more tiny college, situated in upstate New York. Local students have a pure interest to observe topics both during the lectures and out of the classroom. The opportunities to intern and publish impress.   #7: Brown University Brown's Literary Arts  program is known for one of the leading MFAs in the United States. Core requirements are excluded, so students are free to explore additional topics after classes with the help of the stellar English department and screenwriting program. #8: Washington University in St. Louis Enjoy local magnificent MFA program along with the diversity of topics, wide range of scholarships, and creative writing jobs you may find outside the university. #9: Massachusetts Institute of Technology Even though the place has a lot to do with technology, it still has a special creative writing program. It can boast an interesting course in digital media. Besides, except for creative writing, students can master the art of scientific writing. It provides each student with an extraordinary set of skills and more career perspectives.   #10: University of Michigan The University of Michigan  is one of the best American universities in general. It is obvious that it offers a top-notch MFA. The program is aimed to provide every interested student with the excellent creative writing major and good reputation. #11: Johns Hopkins University Remove engineering major from the list of this university, and you’ll get enrolled in the dedicated creative writing program. After passing its valuable courses, one will be able to compose poetry, fiction as well as official reports  and persuasive essays. #12: Colorado College One more small liberal arts college on the list. It is outstanding thanks for the block plan, which makes it possible to concentrate on a single class per three-and-a-half-week block. You’ll take four writing workshops and visit every reading of the Visiting  Writers Series. Don’t forget about New York University writing opportunities as well! How to Make a Final Decision? Don’t lose your head – have a look at the most important criteria to consider when selecting the degree and college which is right for you. Are you interested in the suggested college courses? Analyze which skills you wish to obtain and what each college program offers. Match your personal desires with what the target school proposes. What opportunities are expecting after your classes? Discover whether there will be an opportunity to practice your creative skills outside the college. It can be everything: from campus newspaper to local music or fashion magazine.

Costs associated with occupational and corporate crime Essay

Costs associated with occupational and corporate crime - Essay Example Income tax violation is a popular white-collar crime. According to an article in New York Times, tax evasion costs governments around the globe more than $3.1 trillion annually. Such a whopping loss of more than $3.1 trillion in annual revenue is a very big issue, yet it is exceedingly hard to catch white-collar criminals. According to a report published by the World Bank in 2011, more than 5.1% of global GDP never reaches the government offices in the form of taxes. Europe is currently facing a crisis because of this rampant tax evasion. The highest amount of tax revenue is lost by the US, about $337 billion. The US is followed by South America and Italy (Werdigier). Embezzlement is a kind of occupational crime and research claims that â€Å"the annual cost of embezzlement is 12.42 billion dollars† (Zarka). Yet, research suggests that the highest costs are associated with white-collar crimes. For example, it is claimed that â€Å"the American business community lost $50 bill ion in 1980 to white-collar crime† (Eitzen cited in Long), which is more than 10 times the costs associated with all street crimes. These are just cost estimates because truth is that occupational and corporate crimes cannot be accurately measured. White-collar criminals are hard to catch because of their high position which is why jails are crowded with socially and economically disadvantaged offenders who have committed some kind of low-class street crime. Many problems are encountered by researchers who try to uncover costs associated with occupational and corporate crimes. It is always easier to estimate costs associated with street crimes because people behind these crimes have no occupational or corporate background. These are jobless people typically belonging to poor class. But, the problem with occupational and corporate criminals is that the higher professions and

Fundamentals of Information and Information Systems Essay

Fundamentals of Information and Information Systems - Essay Example This report pertains to the current position of Hewlett Packard (HP) Information Systems, its current business problems and the way ahead for this business organization. My first impression at the outset of the ESS Information System (E-Services Solution)group is to point out that this venture may be successful at the outset given the period 1999 until 2000 but it has all the ingredients of becoming a victim of its own success and potentially damaging the work culture of HP with the so called aim of "infecting" the entire spirit.(see Case Study 2000).I would reach such a bleak conclusion for many reasons which I will discuss below but the pith and substance of my analysis as a management consultant is that "small is beautiful" but once it gets large it becomes ugly. And this is true for HP's future if the ESS information system which is under discussion here is allowed to grown into its organizational management and Information System culture. ... And this is true for HP's future if the ESS information system which is under discussion here is allowed to grown into its organizational management and Information System culture. It can be seen that in 1999 alone through the efforts of the ESS Information System,HP has achieved the status as a leading manufacturer of computer products, including printers, servers, workstations, and personal computers and is generating a revenue of $42.4 billion and net income of $3.1 billion.It has over 80,000 employees worldwide and a strong local presence in Silicon Valley and the Bay Area. The problems of HP and the role of ESS.The case study has given us a bird's eyes view of the historical problems with the management strategy of HP as follows. 1. In 1939 Bill Hewlett and Dave Packard, found HP and were an instant success with their venture and wanted to pursue their own unique way of doing business: "The HP Way." The evolution of the HP Way began early. Even though their decentralized management information system style was a success in the earlier dealing and by 1957 Hewlett and Packard had their own corporate objectives, underling the "The HP Way" through management strategies like Management By Wandering Around, Management By Objectives, and the Open Door Policy inspired later additions, including Open Communication and Total Quality Control .These practices cannot be seen anywhere today and later on the conservative attitude of the HP information system management with in a decentralized company was more product oriented than customer oriented.(refer to Case Study 2000) 2. At this point HP's corporate software and support division and corporate systems

Peter N. Stearns Essay Example | Topics and Well Written Essays - 4000 words

Peter N. Stearns - Essay Example Stern opens each chapter and discussion of a new historian with perceptive beginning and background information that helps to set the historian in a better framework than if it were not to appear. Apart from this, his presence is untraceable, which attests to his ability as a historian himself to remain isolated from his work. Peter N. Stearns is currently Heinz Professor of History and Dean of the College of Humanities and Social Sciences at Carnegie Mellon University. Professor Stearns also has the credit of being the founder along with editor of the Journal of Social History. He has published some 70 articles and fifty books. His present research is on the history of emotions and personal constraints in contemporary American and French culture (for example, weight consciousness). He also continues research in the history of public policy in areas such as social security, mental health, child direction, and infant mortality. He has long been active in developing innovative teaching methodologies, especially in the field of world history. Hulbert and Stearns identify an array of comprehensive social factors. First were demographic shifts that were changing the domestic arrangements of young parents. With the move into big cities from farms or (in the case of immigrants) from overseas, women ever more found themselves secluded from the network of mothers, aunts, and grandmothers who in the past had handed down female intelligence about infant care. Adding to the influence of the experts was, in the case of the middle class, rising prosperity: more mothers had time to become compulsive about their children, an unimaginable luxury for poor and rural women thoughtful with necessities. The experts also appealed to the public's enthrallment with being "modern." Particularly, scientists found a keen audience among extremely well-educated females, middle-class women in love with of the notion that they were raising their children in partnership with up-to-date professionals. In this respect, the allegedly outdated ideas of the preceding generation became a subject for eye-rolling. In 1917, one authority only half-jokingly suggested titling a chapter of his book, "The Elimination of the Grandmother." According to a 1940 poll referred to by Stearns, a good number of parents thought it essential to raise their children differently from how they themselves had been raised. This result would undoubtedly hold today as well. Fueling the stable need for a feeling of up-to-dateness has been the regularity with which child-care experts have claimed to make ever new, breakthrough discoveries. All the way through the 20th century there was a regular flow: new categories of childhood, new pledges, and new fields of specialty. In 1904, G. Stanley Hall published a two-volume thesis on "adolescence" that among other things introduced the word itself into daily parlance. By the 1920's, experts had come up with terminologies like "preschooler" and "toddler," each accompanied by its own theories and suggested techniques. Our own day's contribution to progress has been the detection of such hitherto unheard of creatures as "tweens" and "emerging adults." Apart from the sociological pressures, one very good reason that a good number of parents embraced modern theory is that it was saving young lives. At the

Personal Definition of Innovation Essay Example | Topics and Well Written Essays - 1250 words

Personal Definition of Innovation - Essay Example In this regard, the essay aims to propose a personal definition of innovation taking into consideration a comparative analysis of the concepts of innovation, invention, and creativity. Likewise, a description of the relationship between technical or traditional problem solving and creative or intuitive problem solving would be proffered. An explanation of the importance of innovation to the success of individuals, organizational leaders, organizations, and nations would also be presented. Finally, a determination of the importance of management systems and styles to creating an organization where innovation is enabled would be discussed. Innovation is a process of creative change with a clearly defined purpose of improving a current system or operating process to attain maximized potentials of resources towards a higher level of growth. As a process, innovation needs the application of effective strategies for improved performance. It accurately defines specific aspects to be addressed: a weakness, a threat, a gap in an organization’s current operating system or structure and outlines alternative courses of action that presents possible and viable solutions to the identified dilemma. Innovation, as a change process, is designed with the vision to increase the satisfaction of the organizations’ target market and thereby contribute to the maximization of organizational goals. Innovation is the â€Å"process by which an idea or invention is translated into a good or service for which people will pay. In business, innovation results often from the application of a scientific or technical idea in decreasing the gap between the needs or expectations of the customers and the performance of a firms products† (Business Dictionary, 1). vaccine against market slowdowns and an elixir that rejuvenates growth† (Rigby, et.al, 79). The authors compared innovation to evolving changes in a fashion industry requiring continuous reinvention of product line,

WORKPLACE TRAINING Research Paper Example | Topics and Well Written Essays - 1000 words

WORKPLACE TRAINING - Research Paper Example The term is used in a widespread manner in various organizations these days and is one of the vital phenomena for the success of the workplace. Training pertains to the obtaining of skills, knowledge, and competencies as an outcome of the practical or vocational skills and the knowledge that refers to the particular functional competencies. Training at workplace relates to some special goals such as enhancing an individual’s performance, capability and capacity. It builds the basis of apprenticeships and links with the provision of the fundamentals of employee improvement at the organizations. There are various types of training methods and the primary determinants of these types are associated more to the organization’s distinctiveness than to the characteristics of the individual worker. For instance, there are more formal training types provided in the larger organizations than the training modes available to employees in the smaller companies. The small-scale organizations normally encourage employees to engage themselves in self-training. Moreover, it has been observed that the organizations that stress upon the development of employees’ skills offer more diverse opportunities of training than the companies which do not. Moreover, the organizations which possess a greater degree of unpredictability in the software environment are more likely to provide on-line training. The workplace training is an important element in the employee grooming, retention as well as satisfaction. It increases the employee’s commitment to the organization and develops their physical, cognitive and spiritual dimensions. Besides this, training is a significant aspect because it is aimed upon enhancing the employee performance, and contributes towards the organizational flexibility by adapting to the altering external and internal corporate environments. The training process at organization not

Education Policy and No Child Left Behind Act Research Paper

Education Policy and No Child Left Behind Act - Research Paper Example From the discusssion it i clear that the education in the US schools has been passing through crisis and that is what has been opined by the experts time to time. When Elementary and Secondary Education Act (ESEA) is already active since 1965, what is the need to enact a new legislation under the name and style of the NCLB Act of 2001? In order to get an appropriate reply to this basic question, it will be most pertinent to scrutinize the prevailing state of educational affairs in the US schools. Some of them are worth pondering as being listed in the ensuing paragraph.This essay stresses that  that only 30 percent of students entering high school are able to read at grade level. This simply means that only one-third of the students are ready for college education. Only 50 percent of students of color go for higher studies after finishing their high school. The dropout rates are fairly high at nearly 7,000 high school students on every school day. In the highly competitive job mark et, the high school dropouts are at odds to get a good-paying job. They are more at risk of turning less healthy and die earlier. They are likely to become parents relatively at young age and need social welfare assistance in their life impacting society at large. Students' performance highly depends upon the teachers and their skills. Schools who cater to poor students find it most difficult to recruit certified and experienced teachers.; moreover, almost 50 percent of the teachers leave the profession in five years and 33 percent within 3 years of their joining. Surprisingly, the US schools spend over $ 2.6 billion every year just to replace the teachers who have left the profession. It is astonishing to note that about 70 percent of all eighth-grade students are unable to read at their grade level; this is what has been reported by the National Assessment of Educational Progress in their report card (Alliance for Excellent Education, 2012). The shortcoming comes in the way of the students especially, the students of color and English language learners to pass high school diploma. Research indicates that students drop out due to their weak performances in Math and English. It is quite obvious that students cannot master higher courses at graduate level when they find difficulty in reading and comprehending the content offered in their textbooks. They remain weak in Math because they are unable to understand the theories explaining Math. Arguments against NCLB Some of the major arguments that have been proposed against NCLB can be described as per the following (Carleton, 2012). 1. The program has not been funded adequately by the federal government ever since its inception. 2. How students perform on math and multiple-choice reading tests could be the sole basis of their achievements. 3. All efforts of the teachers are directed and focused toward 'test' because of the fear that in the event of students failing the test their own jobs may be in jeopardy. Expe rts argue that due to this narrow approach creativity has been lost in the education. 4. A special emphasis has been given to math and reading

Public international law Essay Example | Topics and Well Written Essays - 1500 words

Public international law - Essay Example Part 1: Background on the Dispute In 1858, Costa Rica and Nicaragua ratified a Treaty of Limits granting Nicaragua sovereign jurisdiction over a 140 km stretch of the San Juan River, and Costa Rica sovereign rights over its right bank, as well as certain ,navigational rights, "con objetos de comercio."2 An 1888 arbitral award rendered by United States President Grover Cleveland affirmed the Treaty's continuing validity3 and upheld Costa Rica's right to navigate the river with revenue service vessels, but not war vessels.3. In 1916, the Central American Court of Justice held that Nicaragua breached the 1858 Treaty by signing the Chamorro-Bryan Treaty of 1914, granting the United States "exclusive proprietary rights" for the construction and maintenance of an inter-oceanic canal through the river. Excluding a 1956 Agreement on river traffic and protection of the border, no events of significance to the treaty regime occurred for almost seventy years. Starting in the 1980s, Costa Rica p rotested Nicaragua's introduction of new restrictions on navigation, while Nicaragua alleged Costa Rica was exceeding its right of free navigation under the 1858 Treaty. Tensions mounted. On September 29, 2005, Costa Rica instituted proceedings against Nicaragua at the ICJ claiming that Nicaragua was in breach of its obligations under the 1858 Treaty. Nicaragua raised no objections to the Court's jurisdiction. Costa Rica sought an order declaring Nicaragua in breach, and requiring Nicaragua to cease unlawful conduct, make reparation, and give assurances of non-repetition. Nicaragua denied breaching any obligations, asserted that any obligations allegedly breached did not derive from any international law rule, and sought a number of rulings on its power to regulate Costa Rica's navigational rights. Part 2: Summary of the Judgment The July 13, 2009 Judgment provides concrete guidance on the extent of Costa Rica's right to free navigation, defines the scope of Nicaragua's power to reg ulate Costa Rica's right, and identifies a customary right of Costa Rican riparians to engage in subsistence fishing. Specifically, the Court held that Costa Rica has a treaty right to free navigation "for the purposes of commerce," including the transport of passengers and tourists, and that Nicaragua cannot impose visa or tourist card requirements on passengers of Costa Rican vessels. Also, the Court concluded that Costa Rican riparians have the right to navigate between their communities to meet everyday essential needs, as do Costa Rican official vessels used solely to provide essential services to riparian communities. Costa Rica does not have the right, however, to navigate with vessels carrying out police functions, to exchange police border post personnel, or to resupply posts. The Court ruled that Nicaragua has the right to require Costa Rican vessels to stop at the first and last Nicaraguan posts on their route; require river travelers to carry an identity document; issue, but not charge for, departure certificates; impose navigation timetables; and require vessels to display the Nicaraguan flag. Part 3: The Judgement 1. On 29 September 2005 the Republic of Costa Rica filed in the Registry of the Court an Application of the same date,

Electro Physiology of the Human Heart

Electro Physiology of the Human Heart Introduction This chapter is the first chapter in the thesis which gives introduction of the present study. The chapter defines electro physiology of human heart, blood circulation in both pulmonary and systemic in detail, the components in cardiovascular system and heart sounds. It explains in detail the generation of potential due to mechanical activity of human heart and sounds produced due to closure of valves during blood pumping from atrias to ventricles and to respective parts of the body. This chapter presents a detailed survey on literature focusing on different methods to measure and analyse ECG and PCG. Electricity plays an important role in medicine. The control and operation of nerves, muscles and organs are functioning by the electricity generated inside the body. The forces of muscles, the action of brain and all nerve signals to and from the brain are caused by the attraction and repulsion of electrical charges. Many electrical signals are generated to carry out the special functions of the body. These signals are the result of electrochemical action of certain type of cells. The best known signals are electrical potentials of nerve transmission and the electrical signals observed in electromyogram (EMG) of the muscle, the electrocardiogram (ECG) of the heart and the electroencephalogram (EEG) of the brain. One means of obtaining diagnostic information about muscles, heart and brain are to measure their electrical activity. The record of the potential from muscles during movement of is called the electromyogram (EMG). The rhythmical action of the heart is controlled by an electrical signal initiated by spontaneous stimulation of pacemaker cells located at apex of the right atrium i.e. sinoatrial node (SA node). The recording of hearts potentials on skin is called electrocardiogram (ECG). The recording of the electric signals due to electrical activity of neurons in the cortex of the brain is called electroencephalogram (EEG). The present study is to study the electrical activity of heart during its mechanical vibrations. The primary step in investigations of physiological systems requires the appropriate sensors to transducer the phenomenon of interest into a measurable electric signal. The field of biomedical has advanced to the stage of practical application of signal processing and pattern analysis techniques for efficient and improved non- invasive diagnosis. 1.1 Physiology of Heart and Vascular System The analysis of variability in cardiovascular signals is applied widely and many experimental setups were put forward. Spontaneous fluctuations can be observed in cardiovascular function, such as heart rate and blood pressure, even when the environmental parameters are maintained at a constant level as possible and no perturbations influences can be identified. The observations of heart rate fluctuations is related to various cardiovascular disorders, the analysis of heart rate variability has become widely used tool in the assessment of the regulation of heart rate behavior (Timo Makikallo 1998). The study of cyclic variations of heart rate plays an important role in the assessment of both physiological and clinical aspects (Narayana Dutt Krishnan 2000). The heart is actually two separate pumps. A right heart that pumps the blood through the lungs and left heart pumps the blood through the peripheral organs. Each of these composed of atrium and ventricle. Atrium receives the blood and pumps into ventricles. Ventricles supply the main force that circulates the blood either through pulmonary circulation by the right ventricle or through the systemic circulation by the left ventricle(Fig 1.1) The blood, blood vessels and heart make up the cardiovascular system (CVS). The blood and its supply of oxygen are so important to the body that the heart is the first major organ to develop in the embryo. The mechanism in the heart provides cardiac rhythmcity and transmits action potentials through the heart muscle to cause the hearts rhythmical beat. The cardiac event that occurs from the beginning of the next are called the cardiac cycle. Each cycle is initiated by spontaneous generation of an action potential in the Sino atrious node or Sinus node. The cardiac cycle consists of a period of relaxation called diastole, during which the heart fills with blood fallowed by a period of contraction called systole together is known as a beat. The heart is composed of three major types of cardiac muscle; atrial muscle, ventricular muscle and specialized excitatory and conductive muscle fibers. Cardiac muscle is a syncytium of many heart muscle cells which are interconnected with intercalated discs which are of actually cell membranes separates cardiac muscle cells from one another and offers low resistance to ions to diffuse through cells. If one of these cells is excited, the action potential spreads to all of them. The heart is composed of two syncytiums the atrial syncytium that consists of walls of two atria and ventricular syncytium consists of the walls of two ventricles. The atria are separated from the ventricles by tissue that surrounds the atrio-ventricular valvular openings. Potentials are conducted from atrial syncytium into ventricular syncytium through the specialized conductive system called A-V bundle a bundle of conductive fibers. The division of the muscle of the heart into two functional syncytiums allows the atria to contract a short time ahead of ventricular contraction, which is important for effective heart pumping through lungs and peripheral organs. Another importance of the system is that it allows all portions of the ventricles to contract almost simultaneously, which is essential for most effective pressure generation in the ventricular chambers The cardiac cells present in the heart tissue are individually surrounded with an insulating membrane (supporting a potential mV) containing selective permeable ionic channels. The currents through these channels interact with the membrane potential to regulate the activity of the cell. The flow of various ions (Na,K,Ca etc) through out the cardiac tissue is responsible for the propagation of the electrical waves through tissue in turn provides the driving force behind the hearts mechanical contraction and its ability to pump blood through the body. 1.2. Components of Heart The heart is a conical, hollow muscular organ placed obliquely behind the body of the sternum and adjoining parts of the body of the costal cartilages, so that 1/3 rd of it lies right and 2/3 rd to the left of the median plane. The heart measures about 12x9cm and weighs 300 gm in males and 250 gm in females. The human heart has four chambers as shown in fig 1.2. The upper two chambers, the right and left atria are receiving chambers of blood. Atria collects venous blood from the body and about 75% of the blood flows directly into the ventricle even before atrial contraction. The atrial contraction causes an additional 25% filling the ventricles. The hearts lower chambers right and left ventricles are the powerful pumping chambers. The right and left sides of the heart are separated from each other by a wall of tissue .each side pumps blood through a different circuit of blood vessels. 1.2.1. The Right Atrium It is the right upper chamber of the heart receives venous blood from the whole body and pumps it to the right ventricle through right atrioventricular (tricuspid) opening. The chamber is elongated vertically, receiving the superior vena cava at the upper end and the inferior vena cava at the lower end. Deoxygenated blood from the whole body feeds into two large veins, the superior vena cava and inferior venecava, which empty into the right atrium of the heart and the same pumps to the right ventricle. 1.2.2. The Right Ventricle The right ventricle is a triangular chamber which receives blood from the right atrium and pumps it to the lungs through the pulmonary trunk and pulmonary arteries. Externally, the right ventricle has two surfaces anterior and inferior. The cavity of the right ventricle is crescent in section because of the forward bulge of inter ventricular septum. The wall of the right ventricle is thinner than that of left ventricle in a ratio 1:3. 1.2.3. The left atrium The left atrium forms the left 2/3 of the base of the heart and is a quadrangular chamber. It receives oxygenated blood from the lungs through four pulmonary veins and pumps it to the left ventricle through Mitral valve. 1.2.4. The Left Ventricle The left ventricle receives oxygenated blood from the left atrium and pumps it into the aorta, the bodys largest artery. Smaller arteries that branch off the aorta distribute blood to the various parts of the body. It forms the apex of the heart .The cavity of the left ventricle is circular in cross section and has the thickest walls nearly half an inch in an adult because it must work the hardest to propel blood to the farthest reaches of the body. 1.2.5. Valves of the Heart The valves of the heart maintain unidirectional flow of the blood and prevent blood from flowing backward in the heart i.e. the valves open easily in the direction of blood flow, but when blood pushes against the valves in the opposite direction the valves close. There are two pairs of valves in the heart i) atrio ventricular valves ii)Semilunar valves. Atrio-ventricular valves are located between the atria andventricles as shown figure. The right atrio-ventricular valve is formed from three cusps of tissue and is called Tricuspid valve. While the left atrio- ventricular valve has two cusps and is called Bicuspid or Mitral valve. Both valves are made up of a fibrous ring to which the cusps are connected .The cusps are flat and project into the ventricular cavity. The atrio- ventricular valves kept competent by active contraction of the papillary muscles. Semi lunar valves are located between the ventricles and arteries and each of them consist of three half moon shaped flaps of tissue. They are not attached to fibrous ring but are to the blood vessel .The right semi lunar valve between right ventricle and pulmonary artery is pulmonary valve and the valve between left ventricle and aorta is aortic valve .These valves are closed during ventricular diastole. 1.2.6. Superior Vena Cava It is about 7 cm long venous channel which receives blood from the upper half of the body and empties it to the right atrium like other large veins. It has no valves. 1.2.7. The Aorta The aorta is the great arterial trunk which receives oxygenated blood from the left ventricle and distribute it all parts of the body. 1.2.8. Myocardium It is the muscle tissue wraps around a scaffolding of tough connective tissue to form the walls of the heart chamber. The atria the receiving chambers of the heart have relatively thin walls than the ventricles, the pumping chambers. 1.2.9. Pericardium It is a tough, double layered sac which surrounds the heart. The inner layer of the pericardium is known as epicardium rests on top of the heart muscle. The outer layer is attached to the breast bone and other structures in the chest cavity and helps hold the heart in place. The space between the two layers of the pericardium filled with watery fluid which prevents these layers from rubbing against each other during heart beat. 1.2.10. Endocardium It is the inner surface of the hearts chambers lined with a thin white sheet of shiny tissue. The same type of tissue also lines the blood vessels forming continuous lining throughout the circulatory system. The lining helps blood to flow smoothly and prevents clotting of blood in the circulatory system. The heart is nourished not by blood passing through, but by the blood vessels also known as coronary arteries which encircle the heart like a crown. About 5% of the blood pumped to the body enters the coronary arteries, which branch from the left ventricle .Three main coronary arteries the right , the left circumflex and the left anterior descending nourish different regions of the heart muscle. From these three arteries small branches arise to provide a constant supply of oxygen. 1.3. A Detailed Description of Vascular System The cardio vascular system is concerned with the transport of blood and lymph through the body. It may be divided into four major components, the heart, the macro circular i.e. blood vessels arteries and veins, micro circular i.e. capillary and lymph vascular system i.e. water and other components of blood plasma. The cardio vascular system (CVS) controls the blood pressure by altering the heart rate and compliance i.e. elasticity of blood vessels. (Isla Gilmour 1995). 1.3.1. Arteries Arteries transport blood from high pressure to body tissues as their structure permits them to expand and contract under different pressures due to the presence of elastic fibers. The main artery of the heart is aorta, which starts from the left ventricle transporting oxygen and nutrients to all body tissues. The presence of elastic fiber enables the arteries to expand when each pulse of blood pumped by the heart and regains its original shape when tension is released. Like all blood vessels the inner layer of arteries is known as tunica intima, composed of a single layer of flattened endothelial cells fitted together to form a smooth, continuous tube. In large arteries the same layer is supported by thick band of elastic fibers. The middle layer is known as tunica media consisting of smooth muscle and elastic fibers. In very large arteries the outer layer is known as tunica adventitia also contains elastic fibers and connective tissue. 1.3.2. Veins Veins transport deoxygenated blood at low pressure toward the heart and act as reservoirs of different capacities to maintain a steady return of blood to heart. The veins of systemic circulation terminate at bodys largest veins superior and inferior vena cava which empty into the right atrium of the heart. The walls of the veins are thinner and contain little elastic fiber with greater internal diameter. These structural properties help them to stretch and store the blood. Since the pressure in veins is low some structural changes is needed to prevent blood from downward pull of gravity. The veins in the lower body contain special one-way valves prevent the accumulation of blood in the legs and feet. During exercise the muscles are in extremities, relaxing and contracting alternately squeezing the veins to force the blood upward towards the heart. The tunica media of veins is thinner and contain less elastic fiber and smooth muscle to function at low pressure and serving as reservoirs to maintain a steady return of blood to the heart. 1.3.3. Arterioles The functions of arterioles are to distribute the blood and pressure reducing valves. They play an important role in determining the blood pressure. The arterioles have smooth muscle in their walls and do not stretch rather act as pressure reducing valves between the arteries and capillaries. They prevent delicate capillaries from high pressure of blood in the arterial system. The degree of muscular tension in the walls of arterioles decides their internal diameter in turn changes the resistance of blood flow in arterioles. As they affect the blood pressure because they account for a large component of the peripheral resistance to blood flow. Blood pressure is the product of total peripheral resistance and cardiac output. 1.3.4. Venules The function of venules is to drain blood from the capillary bed into the venous system. 1.3.5. Capillaries Capillaries are very small blood vessels their diameter ranges from 4-15 ÃŽ ¼m. The sum of the diameters of all capillaries is significantly larger than that of the aorta which results in decrease of blood pressure and flow rate. Capillaries are composed of a single layer of flattened endothelial cells fitted together to form a continuous tube. This results in a very large surface to volume ratio. The low rate of blood and large surface area facilitate the functions are * Providing nutrients and oxygen to the surrounding tissue. * The absorption of nutrients, waste products and carbon dioxide and * The execution of waste products from the body. 1.3.6. Lymphatic Vessels Parts of the blood plasma will execute from the blood vessels into the surrounding tissues because of transport across the endothelium. The fluid entering tissues from capillaries adds to the interstitial fluid normally found in the tissue. The surplus of liquid will return to the circulation .Lymph vessels are dedicated to this unidirectional flow of liquid, the lymph. The lymph vessels can be divided into three types depending on their shape and size. Lymph Capillaries These are larger than blood capillaries and very irregular on shape. They begin as blind ending tubes in connective tissues. Lymph Collecting Vessels They appear almost similar to lymph capillaries but a bit large and form valves. The lymph is moved by the compression of the lymph vessels by surrounding tissues. The direction of lymph flow is determined by the valves Lymph Ducts They contain one or two layers of smooth muscle cells in their wall and form valves. The walls of lymph ducts are less elastic and during contractions contribute to the movement of lymph towards the heart in addition to the compression of the ducts by surrounding tissues. 1.3.7. Relations to Other Systems and Organs The heart and vascular system perform almost the same function to provide oxygen, nutrients and harmonic to the cells of the body tissue. They can be considered as one unit rather than two, because each is equipped to carry out half of that function. The vascular system is also closely related to the adrenergic receptors and the autonomic nervous system, which together control important aspects of its function. The alpha adrenergic receptors are the smooth muscle cells in arteries, veins, arterioles and venules. These receptors bind molecules released by cells of the autonomic nervous system and respond by contracting. 1.4. Blood Circulation -Systemic and Pulmonary The heart basically a double pump provides the force to circulate the blood through two major circulatory systems, the pulmonary circulation in the lungs and the systemic circulation is in organ system that transports substances to and fro from cells. The blood in normal individual circulates through one system into before being pumped by the other part of the heart to the second system. The heart is a muscle composed by cells containing small filaments of actin and myosin. These proteins interact in the sense of forming actomyosin during muscle contraction, thus leading to the main purpose of the heart: pumping the blood through the circulatory system (Manuel Duarte Ortigueiva 1959). The synchronous nature of contraction of heart results in the efficient pumping of blood through the pulmonic and systemic circulation (J.Olansen et al 2000). The circulatory system can be thought of as a closed loop circulation system with two pumps. One way valves keep the flow downward through the pumps. 1.4.1. Systemic Circulation The heart ejects oxygen rich blood under a pressure about 125 mm Hg from main pumping chamber left ventricle, through the largest artery the aorta. Subdivided into smaller arteries in turn divided into even smaller arteries called arterioles and finally into a very fine meshwork of vessels called the capillary bed. Capillaries permit to dissolve oxygen and nutrients from the blood to diffuse across the fluid, known as interstitial fluid that fills the gaps between the cells of tissues of organs. The dissolved oxygen and nutrients enter cells through interstitial fluid by diffusion across the cell membranes. Mean while carbon dioxide and other wastes leave the cell diffuse through the interstitial fluid, cross the capillary bed and enter the blood. The blood collects in small veins called venules gradually join together to form progressively larger veins. Finally the veins converge into two large veins, the superior vena cava and the inferior vena cava bringing blood from upper half and lower half of the body respectively. Both of these main veins join at the right atrium of the heart. 1.4.2. Pulmonary Circulation The deoxygenated blood returning from the organs and tissues of the body stored momentarily in the reservoir i.e. right atrium, during weak contraction (5 to 6 mm Hg) the blood pushed into the right ventricle. On the next ventricular contraction this blood is pumped at a pressure of about 25 mm Hg through pulmonary arteries to the capillary system in the lungs. At this site microscopic vessels pass adjacent to the alveoli or air sacs of the lung where it exchanges oxygen from the membrane to the blood and leaves carbon dioxide from blood to the same membrane. The freshly oxygenated blood then travels through the main veins from the lungs into the left reservoir i.e. left atrium of the heart. During weak arterial contraction (7 to 8 mm Hg) blood enters the left ventricle. On the next contraction of the left ventricle sends blood to the aorta and then to general circulation. On average a typical adult has about 4.5 lts of blood and each section of the heart pumps about 80 ml in each contraction. About 30 sec to 1 min is needed for the average red blood cell to complete a full circuit through both the pulmonary and systemic circulation. The blood volume is not uniformly divided between the pulmonary and systemic circulation. At any one time 80% of the blood is in the systemic circulation and 20% is in the pulmonary circulation. Of the blood in the systemic circulation about 15% is in the arteries, 10% is in the capillaries and 75% is in the veins. In the pulmonary circulation about 7% of the blood is in the pulmonary capillaries and the remaining is almost equally distributed between the pulmonary arteries and pulmonary veins. 1.4.3. Additional Functions In addition to oxygen, the circulatory system also transports nutrients derived from digested food to the body. These nutrients enter the blood from the walls of the intestine carries the nutrients to the liver for farther metabolic processing. The liver stores variety of substances such as sugar, fats and vitamins and releases glucose to the blood as needed. The liver also cleans the blood by removing waste products and toxins. After the blood is cleaned, enter the veins converge to form the large vein that joins the vena cava at right atrium. The circulatory system plays an important role * In regulating body temperature * To collect chemical messengers called hormones from hormone producing glands and transports to specific organs and tissues to regulate bodys rate of metabolism, growth, sexual development and other functions. * With immune system and coagulation system, the immune system is a complex system of many disease fighting white blood cells and anti bodies circulate in the blood and are transported to sites of infection. The coagulation system is composed of special proteins called clotting factors which circulate in the blood. When ever blood vessels are cut to torn, the coagulation system works rapidly to stop the bleeding by forming clots. Other organs support the circulatory system are the brain and the parts of nervous system constantly monitor blood circulation, sending signals to the heart or blood vessels to maintain constant blood pressure. New blood cells are produced in the bone marrow and old blood cells are broken down in the spleen, where iron and other minerals are recycled. Metabolic waste products are removed from the blood by kidneys which also screen the blood for excess salt and maintain blood pressure and to maintain blood pressure and to balance minerals and fluids of the body. 1.5. Heart Diseases Heart disease has become very common nowadays due to changes in life style. Many of these diseases are due to either increase the work load of heart or reduce the ability to work at normal rate. 1.5.1. Tachycardia There are many factors that are responsible for development of heart disease. One such factor is High blood pressure (Hypertension) which causes the muscle tension to increase in proportion to the pressure. A fast heart rate (Tachycardia) increases the work load. 1.5.2. Heart Attack The heart disease that causes most deaths is heart attack. A Heart attack is caused by blockage of one or more arteries to the heart muscle. During and after heart attack the ability of the heart is seriously impaired. Bed rest and giving oxygen reduces the work load on heart which increases the oxygen content in the blood so that blood pumped by the heart will be less. Alternate method to reduce risk of heart attack is the regular exercise program which opens alternate routes in cardiovascular system. 1.5.3. Congestive Heart Failure Another common disease is congestive heart failure which is due to enlarge in size of the heart reduce the ability for adequate blood circulation. Applying law of Laplace, if the radius of the heart is doubled, the tension of the heart muscle should be doubled which in turn reduces the efficiency of the heart muscle to maintain the same blood pressure. Since the heart is stretched it may not be able to produce sufficient force to maintain normal circulation. Stretched heart muscle is less efficient than the normal. It consumes much more O2 for the same amount of work. 1.5.4. Bradycardia Patients with inadequate electrical signal in the heart muscle will affect the work load of heart. The artrioventricular node i.e. between Atria and Ventricles is fatty and does not conduct electric signal and ventricle receive no signal from Atria, but being natural pacing centers which provide a pulse. The resulting heart rate is 30 beat/min i.e. Bradycardia results semi invalidism. 1.5.5. Pace Makers If hearts electrical signals are inadequate to stimulate heart muscles, artificial pace makers are available. To improve the quality of life of faulty atrioventricular nodes, artificial pacemakers are developed. The pacemaker contains a pulse generator that put out 72 beats / min. The pace maker is put just below the right collarbone. It lasts for 2 years and impervious to body fluids and do not cause tissue reaction. 1.5.6. Valve Defects Another heart disease is defective heart valves. These are of two types. 1) The valve either does or opens wide enough (stenosis). In stenosis large amount of work is to be done by heart to obstruct the narrow opening. 2) It does not close well enough (insufficiency).In insufficiency some of the pumped blood flows back and the amount of blood in circulation is reduced .Both types can be replaced by artificial valves. 1.5.7. Cardiovascular Diseases Aneurysm Some cardiovascular diseases involve the blood vessels. An aneurysm is a weakening of the wall of an artery which results increase in its diameter in turn increases the tension in the wall proportionately. If it is ruptured in brain, a type called Cerebrovascular accident (CVA). A more common blood vessel problem is the formation of sclerotic plaques on the walls the artery which causes turbulence in blood flow increases the blood velocity at that point with a decrease in wall pressure due to Bernoullis theorem. A Disease in Varicose Vein Veins with defective valves which allow the blood to flow backward become enlarged or dilated to form the varicose veins. During walking or other exercise, the contraction of the muscle forces the venous blood toward the heart called venous pump. At various points along the veins there are one way flaps or valves that prevent the blood from going back. If these valves become defective blood run backward and pool up in the vein becomes varicose. The standard treatment for varicose veins is surgical removal of the offending vessels. There are sufficient parallel veins to carry the blood back to the heart. Stiffness of RBC Membrane In some cases, mainly in smoking, the membrane of RBC s becomes stiff. There may not be normal flow of blood in the vascular system. Blood may become viscous leading to Thrombosis. 1.6. Electrophysiology of Heart The rhythmical action of the heart is considered by an electrical signal initiated by spontaneous stimulation of special muscle cells located in the upper right hand corner of the right atrium near the superior vena cava. This area is known as sino atrial node (Fig 1.5). Cardiac electro physiology is dedicated to the study of the electro chemical activity of the heart. Studies include electrical activation of individual cells as well as the system- level activation, which results in normal or abnormal heart rhythm. (J.Olansen et al 2000). The complex system found by the Autonomous Nervous System (ANS) and the heart is modeled as if it was a modulation system, where the first generates a signal that modulates a sequence of pulses which excite the heart (Manuel Duarte Ortigueira et al 1959 ). The sinus rhythm fluctuates around the mean heart rate, which is due to continuous alteration in the autonomous neural regulation i.e. sympathetic and parasympathetic balance. Periodic fluctuations found in heart rate originate from regulation related to respiration, blood pressure (baroreflex) and thermoregulation (Pauli Tikkanen 1999). Cells in the SA node generate their electrical signal more frequently than cells else where in the heart. These impulses spread rapidly through inter nodal pathways to Atrioventricular node (AV node). At this node the signal is delayed so that all muscle cells of the atria contract virtually in unison. Now the impulse conducts through fibrous connective tissue between atria and ventricles known as Atrio ventricular bundle (AV bundle). AV bundle conducts the signal through left and right bundles of Purkinje fibers which conduct the cardiac signal to all parts of the ventricles. 1.5.Fig. Electrophysiology of the heart. 1.6.1. Sinoatrial Node The sinoatrial node is a small, flattened ellipsoid strip of specialized muscle about 3 mm wide, 15 mm long and 1mm long located at the upper right hand corner of the right atrium immediately below and slightly lateral to the opening of the superior vena cava. The Sinoatrial (SA node), the atrioventricular (AV node) and the Purkinje system can be regarded as potential pacemaker tissues in heart. As the fastest depolarization impulse spreads through the conduction system to other pacemakers before they spontaneously depolarize, the sinoatrial node usually defines heart rate (Pali Tikkanen 1999 12). The sinus nodal fibers connect directly with the atrial muscle fibers, so that any action potential generates at the sinus node spreads immediately to the atrial muscle wall. For this reason Sinoatrial node is also known as pace maker of the heart. It generates the impulse at the rate of about 70/min and initiates the heart beat. However this rate may increase or decrease by the demand of blood supply to the body. Three types of membrane ion channels play an important role in causing the voltage charges the action potential. They are 1) fast sodium channels 2) slow calcium-sodium channels 3) potassium channels. As the ions move in muscle cells in fractions of second creates action potential at the Sinoatrial node.
