Interactive Training of Hospitality Operations Personnel Essay

Interactive Training of Hospitality Operations Personnel - Essay Example The rise in employee turnover costs and the increased use of technology in the industry further emphasizes the need for training (Sheldon and Gee, 1987). Internet based 'interactive training' programs (an umbrella term that includes both computer based and multi-media training) of hospitality operations staff provides access to on-demand training, tracking of each trainees' progress, as well as in-depth reporting of each trainee (hotelonline.com, 2000). The training is provided with an interactive format that includes text, animation and audio. A successful interactive training program in the hospitality sector ensures consistency in providing a quality environment for employees, guests and visitors. It is a cost effective way of upgrading skills of hospitality personnel, the benefit of which can be visible from consistent and quality delivery of essential guest services and avoidance of any litigious situation. In the present age of IT dominance, interactive training of hospitality personnel is an integral part of the industry without which introduction of technologies in the hospitality sector would not have the desired result. ... With new innovations in the IT sector, more and more hotels are equipping themselves with the tools of modern technology to ensure global connectivity to their customers, particularly corporate executives. Without upgrading, the knowledge and skills of hospitality personnel rapidly gets outdated. In the competitive atmosphere of modern day hotels it is crucial to satisfy and win the loyalty of each customer. A satisfied customer apart from becoming prospective customer for the future may also bring in more customers through positive multiplier effect (Duprey & Kearsley, 2005). In the new e-economy, the value of human capital, meaning mainly employees' skills, competencies, and knowledge is greater than any other form of business capital and can crucially drive competitive advantage (Cohen & Levinthal, 1990). Increase in skills leads to improved performance which enables the employer to meet the needs of the employees also helping in retention of the precious talent. "No hotels can have excellent operations without excellent employees and that requires excellent human resource practices" (Siguaw & Enz, 2000, p.48). Human resource skills have always been an important element in the hospitality industry. "Friendliness and a willingness to serve others are the tools of the hotel trade, and training is the sharpener that refines the tools into hospitality machines" (Higley, 2004). Proper attitude starts with management and ends with diffusing it to all the staff of the hotel. It is of utmost importance to make right impression at the front desk which is reflected through a positive, outgoing and friendly attitude and also through efficient service. Increasingly intense competition, high customer expectations and retaining

Employee and Customer satisfaction Assignment Example | Topics and Well Written Essays - 1500 words

Employee and Customer satisfaction - Assignment Example In real sense, within the government, satisfied workers are individuals who the government could do better without them. Satisfaction of employees does cover the basic needs as well as concerns of employees. It happens to be a good point to start at, however, it typically stops short of what matters really (Susan, 2015). Inefficient HR department which does not place a right employee to do the right job as well as tracking the employees’ individual performance makes employees dissatisfied. The executives in HR department need to listen to the views of the department’s employees (MBA Lectures, 2011). Work pressure in the HR department could cause employee dissatisfaction. When the HR bosses mask the HR employees to finish many tasks within a stipulated time, it brings about work pressure on HR workers. The employees will develop some sort of aversion to the work (Rose, 2015). Employee educational background- where an employee lands on a job of distinct profession from his training then the employee will have to be dissatisfied with the work. This happens to be quite natural since the worker will not be able to match his/her preference for such job kind (MBA Lectures, 2011). Work politics within the HR department- as well as inability for an employee to fit in an office environment will definitely lead to dissatisfaction. It leads to reduced efficiency as well as productivity of an employee. Reduced salaries within an HR department will definitely make HR employees dissatisfied with their jobs. HR employees feel like they should be paid a suitable price for services they undertake. No one is willing to work for a trifling amount (MBA Lectures, 2011). Organization- when employees are dissatisfied their performance go down. This happens be a big blow to the organization in the sense low productivity leads to less profits as well as poor public welfare, not forgetting that these are the main goals for an

The Ethnography of Anthropology Essay Example for Free

The Ethnography of Anthropology Essay As with the study of any anthropological culture, with ethnography there are no set methods for documenting that culture or human societies, but much can be said about the methods of attempting to understand a culture by investigating how, exactly, that culture is unique. This tact can take the form of looking into a society’s housing conditions, how they raise their children, how they are educated, what types of religions they may follow, and even how they might bury their dead. In this, ethnographic studies have virtually taken the form of historical case studies—placing a culture down on paper as if the writer were there and intimately understood the culture. With that said, a look will now be taken into a few of the major ethnographies and the methods of the anthropologists that conduct the research within them. It has been said that a degree in anthropology would not be complete without an understanding of ethnographic research and the art of defining a culture down to its smallest and most fundamental aspects. From that ideal, the study of ethnography branched into an understanding of cultural mores (more than studying how and why people bury their dead), and a look was taken into how a society might communicate (both verbally and nonverbally). For example, if an ethnographer were to study high school students of the twenty-first century, they might notice that the cell phone forms the lifeline of communication among the young in society, and from it, an entirely new language of the â€Å"instant message† was formed—a language that most modern day â€Å"elders† do not comprehend or understand. In this, an ethnographer might note the disconnect between the young and the old in America today. And that, in its most basic form, is the basis for ethnographic research and just one method for employing ethnography to study a culture. Now, a look will now be taken into a few of the anthropologists that were essential for the major ethnographies along with a comparison of their research methods, successes, and failures. To begin with, Annette B. Weiner wrote â€Å"The Trobrianders of Papua New Guinea† as an ethnographic study of the relationships between man and woman and their differing perspectives (and courting rituals) including a somewhat feminist approach on the value of a woman and her work within their society. In 1990, Weiner’s ethnographic work was made into a documentary which focused â€Å"on [unexpected] Trobriand social practices – female exchange, mourning practices, cricket, magic, competition between male chiefs, marriage, Christianity on the island – to provide a picture of modern Trobriand society† (Alexy, 2002, par. 1). When Weiner began her research of the Trobriand culture, she â€Å"had planned to research tourism and local crafts† (par. 2), while instead she found herself drawn into â€Å"explicit and overwhelming female exchange†¦ a ritual mourning ceremony directed by women† (par. 2). In Weiner’s studies, her research also reveals â€Å"other dimensions of Trobriand society beyond these ritual exchanges† (par. 4 ). In this, Weiner’s ethnography goes beyond the traditional mode of one aspect of the culture and instead encompasses a vast amount of the societal mores of the Trobriand. Her failings, if there are any, can be defined by the purely feminine approach to her studies, as even the documentary is filmed from the female perspective, which, ultimately, excludes a great deal of the male perspective and culture from her ethnography. Sharon Graham Davies wrote â€Å"Challenging Gender Norms: Five Genders among the Bugis in Indonesia† as a case study in cultural anthropology to demonstrate the larger value of multiple genders within the society of Sulawesi, on the Indonesian Island versus the two genders that most societies recognize. Essentially, there is the traditional male and female, and then the Bugis also encompass and recognize the androgynous Shaman, and the male and female transgendered (including gay and lesbian) within their society. For their part, the Bugis can be seen as a liberal New York City melting pot of genders, without judgment, and without shame for their chosen paths in life. Davies, in her ethnology, represents a new theory on the ideal of gender and the social mores founded within each, enlightening the subject of challenging traditional gender mores. Further, Davies refers to their gender choices as just that, â€Å"gender negotiations† (Davies, 2001, par. 3) in which both male and female â€Å"to conform to [the] ideals† (par. 3). of most modern societies. More, Davies explained of her work that she refers to â€Å"hir and s/he to challenge readers to [imagine] a subjectivity beyond the dichotomous her/his, she/he. The use of hir further signifies the possibility of a third gender not contingent on crossing from one normative gender to the other. Moreover, neither the Indonesian nor Bugis languages discriminate between gender† (Davies, 2001, endnotes). In this effort, Davies is attempting to define, categorically, the gender difference and non-discrimination that the Indonesian people show. As a gender/sexuality ethnologist, Davies’ research methods seem to comprise the study of the hierarchy within the society and the impact and effect of a chosen gender. Her fundamental stance included the major roles and duties of women, especially, and she defines how â€Å"the hierarchical order of a woman’s duties shows that only after a woman has married and produced children is it her duty to be a member of society. Indeed women may not be considered adults until they have married heterosexually† (Davies, 2001, par. 13). In this, perhaps, the failings of Davies, like Annette Weiner, can be blamed upon her feminist approach to her ethnology of the Bugis and their gender relationships. While her research does encompass the duties and roles of men as well, her main focus is upon the objectification of women and the shocking hierarchal implications (indeed there is some judgment, even in within the Bugis) of their chosen gender identities. Colin M. Turnbull wrote â€Å"The Mbuti Pygmies: Change and Adaptation† as a case study in cultural anthropology of the Mbuti pygmy hunter/gatherers of Zaire. His ethnology focuses on the social organization and environmental tasks and objectives of the pygmies in correlation to their relationship with their non-hunter/gatherer neighboring villages. Turnbull’s work is purely a historical outline of the location and social structure of the Mbuti pygmies in which he notes their settlement location, languages, hunting party structures, and hunting party jobs, like archer, spearman, etc (Martin, n. d. , par. 2). Turnbull discovered that â€Å"only political identity they have is in opposition to the village cultivators† (Martin, n. d. , par. 4) and the â€Å"relationship between the Mbuti and the villagers is maintained on several different levels, centering around trade† (par. 9). In this, Turnbull’s ethnography is highly focused upon one essential aspect of the Mbuti tribes. He does not go any deeper into their culture than trade and hunting, and little is mentioned about social relationships of women within the tribe itself. Indeed, like other ethnographers, Turnbull’s focused approach could be seen as a failing in that there is obviously much more to the Mbuti tribe than their hunting techniques and trade relationships. However, while there must be much more required to understand the Mbuti culture and people, Turnbull’s anthropological research shows, as a case study, and important and driving aspect of the culture. Evon Z. Vogt wrote â€Å"The Zinacantecos of Mexico: A Modern Maya Way of Life† as an ethnographic case study on the life, rituals, economics, and reproduction in Zinacantan. The main focus of his ethnography, however, is the Zinacanteco belief system and how their beliefs serve as the philosophy for their lives and rituals. Of the ethnographers, Vogt is one of the few to spend time in his documentary to relate his various field work methods and explanations. More, Vogt goes deeper into the Zinacantan society, remarking on the food that they eat and the clothing that they wear explaining that â€Å"virtually all women know how to weave the full range of clothing in the normal Zinacanteco costume; but a few items, like ceremonial clothing and the intricate blouses presented to godchildren, are often produced by specialists within the community† (Cancian, 1972, 14). Indeed, Vogt provides an incredibly detailed account of the Zinacanteco way of life, surveying it as closely and as in-depth as if he had lived within the culture since birth. In this, Vogt’s account seems personal and literally every aspect of the society and culture seems accounted for. While he spends a great deal of his ethnographic survey on the belief system, it can be seen from his studies that the religious ways and methods are the driving force for the Zinacanteco and that the most important aspect has been thoroughly covered. Finally, William F. Wormsley wrote â€Å"The White Man will Eat You! An Anthropologist among the Imbonggu of New Guinea† as a case study into the cultural and social structure of the Imbonggu’s, which includes such aspects as leadership, marital obligations, and even magic and religion. Wormsley is the most unique of the major ethnographers because he spends time focusing on the truth of documenting a tribe, and the reactions, emotions, and ideals of the anthropologist himself while attempting such an ethnographic study. Mostly, Wormsley’s work stands out among the rest because of his personal immersion in the culture and society. While the other ethnographers, especially Annette Weiner, documented their studies with a point of view, their attempts were to show the cultures and societies without much interaction, to show the society in its cultural bubble without outside influences and distractions. While Wormsley doesn’t impede the culture he is studying by inserting himself into the historical commentary, his immersion impacts a reader into understanding the trials and tribulations from the ethnographer’s point of view, and that makes for a unique and interesting read. Overall, William F. Wormsley, Evon Z. Vogt, Colin M. Turnbull, Sharon Graham Davies, and Annette B. Weiner are among the foremost ethnographers in the study of cultural and sexual anthropology. While their research has proven to be limited in the nature of what they encompass, all highlight the fields within their chosen cultures that they intended. And of them, Wormsley stands out as the ethnographer most immersed in his ethnographic study as he detailed the life and means of his own documentary. References. Alexy, A. (2002).

Current Education System Impact on Creativity

Current Education System Impact on Creativity Abstract This paper discusses how the current system education in Latin America kills creativity. The paper explains that standard test need to be reorganized and how the system would improve. Then it will show how free time is important for each student to have better knowledge. Finally, you will find how is the methodology of the system to reflect on the path we are following. Also along the paper there are some comments to solve the problem because that problem is affecting childhood. Keywords: Current educational system, creativity, students , methodology, childhood. The current education system kills creativity Does every person have the same opportunities in the current education system? The answer is clear No. Nowadays the current education system is based on a few important subjects such as maths, science and language but it does not focus on people who like to dance or sing. In the article The case for disruption in Latin Americans classrooms (Segan, 2016), Susan says that many schools in Latin America continue to use antiquated models for education. For many years education system in those developing countries has not had a great change, even though humans are developing every moment; our cars improved, our computers improved, and our engines improved. However, in the article Inteligencias Mà ºltiples: La teorà ­a en la prà ¡ctica. (Howard), Gardner suggest that we have been used this education system since industrial revolution. In those days this system worked because the world necessities only consisted on memorizing or following instructions. This education system uses those old techniques such as memorization but in todays world skills such as creativity, imagination, and innovation are needed. Gardner also suggests that there is more than only one intelligence so why does education system only focus on some of them? We have different ways to learn, create, and innovate so we cannot keep on using this system. Each person is different and unique so the system cannot judge us equal. Also, the world has changed since the industrial revolution and our necessities have changed too. Now we have many people without work because the system does not prepare them for new labour requirements because the world need more people who can solve problems. On top of that the current educational system believes that some subjects are more important than others such as math and dance but nothing farther than the truth because a dancer can create and innovate with his/her body. However we sometimes think that a mathematic or a logic person only has theoretical knowledge and c annot apply that kind of knowledge in real life, but that is not true in all cases. However the current system education guides us to think in a unique way. For those reasons by me there are 3 issues with the current system education that kills creativity. Standard test are not suitable for all students First of all, standardized tests are one of the biggest problems in the education system. In the article Inteligencias Mà ºltiples: La teorà ­a en la prà ¡ctica. (Howard) , the author says that there are several different intelligent. Based on this information in my view standard test is not a good way to evaluate a students progress. Standardized test are based on questions to benefit certain people with specific skills. For example, in Ecuador there is an exam called ENES which benefit people who have logical and linguistic intelligence. However, people who do not have those skills cannot pass this exam so they believe that they are not able to study anything. Those exams are created to benefit specific skills such as the ability to calculate math problems or create and solve equations. However, in the article The case for disruption in Latin Americans classrooms (20 May 2016), Susan Segal says that the way students learn and what they need to learn is rapidly changing so the ma in problem is Can a unique exam apply to everyone? According to Gardner there are different intelligent, skills and necessities so those kinds of exams do not work because each person has different skills and necessities. By the contrast this kind of test judges everyone as equals. Another issue is that a test takes a lot of time to be answered and is exhausting for students. People who control educational system should change test methodology and try to make them less stressful. With this in mind if tests were more practical, students would increase their knowledge faster and they would develop new important abilities. For example, with a test is difficult to value the real awareness. By the contrast by creating projects would be better to evaluate each student. By creating projects students develop skills such as to resolve real problems, create new ideas or improve leadership. In science, we dont begin by knowing the answer-we value the process ¨ (Ossola, 2014). That shows us that sometimes we need to move our hands to learn better. If we do not make the process we will have knowledge but we would not be able to apply that knowledge in the real world. One solution for this problem would be to decrease the number of tests and increase the number of pro jects but tests could be more practical because now there are a lot of tests that only exploit our ability to memorize. At the present time our world is more competitive and big ideas are required to improve our world. In this way test should be related to take advantage of those skills and guide us to use them to resolve real problems. Time should be better spent Secondly, the lack of free time for students is another problem in the current education system. Time is important for every one because we can use it on different things such as relaxing, doing homework, playing or whatever we like. However, what happens if we spend too much time in classes? We do not take advantage of the hundred percentage of our time because we have exhausting classes with a long schedule. In some cases each subject is token 2 hours per day, so teachers cannot stay those schedules and neither do students. Thus students get stressed easily and cannot pay attention very well. Also students who do not like some subjects spend their time in other activities such as playing on their cell phones, chatting or joking. Hence time is not taken advantage of in classes, so schedule should benefit students and teachers. Each one works better if they are relaxed. A good example to take advantage of time is in the article, A Young Tinkerer Builds a Windmill, electrifying a nati on. (2007). Where Sarah Childress says that while William Kamkwanba quietly plowed through homework, his classmates were busy gossiping and checking their Facebook profiles. He took advantage of his time while his partners did not spend time in a good way. Also William Kamkwanba created a new project without any pressure. He was relaxed and he worked better. Also he did not spend his time in classes because he was forced to work with his hands so he worked better if he was moving his hands. Also William Kamkwanba had done his work without any teacher; he is a great example of self-preparation. A great example of this is when he built a wind will only with a book. This shows that the only limit is our imagination. He worked every minute in his project so his project could be done. Based on that the scholar system should change the schedule and exploit each ones abilities taken advantage of every minute in classes and give more free time to decrease stress. Also the system should cons ider different ways to exploit time. As we can see in Willians example creating projects is one of the best solutions because with projects we are able to think outside the box and not waste time. Time is too important because we cannot recover lost time. The current methodology no longer works Finally, the current methodology based on memorization is an impediment to learn because creative people are wasting their time. Nowadays memorization is an important base in our education system. However not all students are able to learn in this way also this way of teaching does not teach critical thinking skills. If we think on memorization, scientist comes up our mind because some people believe that they are like robots and they only memorize their books. However , in the article Scientists Are More Creative than You Might Imagine (Nov 12, 2014). Ossola Alexandra believes that scientists are like artists as well. Scientists are able to create because they need new ideas. Also projects are based on new ideas and a scientist always does projects. If a scientist only has the ability of memorize, he would fail in the science world. However the education system, which I described before, is not useful for different skills based on creativity, it focuses in creating head knowledge. S chools only teach what they need to learn they only teach facts, but sometimes they do not teach how they can apply that knowledge and students are like machines, empty machines. A student can follow instructions but the real question is, can that student think by himself. Curiosity, initiative, leadership are not used in classes and they are abilities that can help a student not only in his studies also in his life. Innovative solutions and new technologies are emerging around the world (Segal Susan, 2016). That means that there are a lot of people with good ideas. However in Latin America those techniques such as creativity, collaboration, problem-solving and others are not taken of advantage because those skills are killed in schools or high schools. The system only teaches us to follow one way. Nevertheless kids are living a different reality so they need different skills. Memorization is an antiquate technique that should be changed by techniques like leadership or adaptability initiative. To sum up In conclusion if the current education system in Latin America based on memorization and head knowledge are not useful in the world today, we should find a solution to help people with fresh ideas, innovation or creativity. Today we are judge a fish by its ability to climb that shows us that we are not creating people who can solve real problems because the education system is focused head knowledge. However, the world need more than knowledge as developing countries we should be able to pick the best of other education systems from countries with better development. Also education system is too important for each one because kids are formed in this system and they will be the future of our society. Nevertheless we are killing their abilities and we are formed robots that only have linear thinking. Is true that there are problems so we need to identify which are they and try to find a solution.

Euthanasia and Christian Beliefs Essay -- Euthanasia Mercy Death Healt

Euthanasia Euthanasia is defined in the Chamber’s English Dictionary as â€Å" the act or practice of putting someone painlessly, or as gently as possible, to death†. There are various forms of Euthanasia, which I must explain before referring to the teachings of the different Christian denominations. The most common of them is Voluntary Euthanasia, where the patient decides for themselves, that they would prefer to be dead. They might decide at the time, or perhaps they might have written a ‘living will’ instructing doctors to kill them if they are ever in a situation where they will never be conscious again. There is also In-voluntary Euthanasia, were someone else decides against the patient’s wishes that would be better off dead, and enforces it in the act of killing them. Therefore it is often out-classed as Euthanasia, because it is not ‘gentle’. Non-voluntary Euthanasia takes place in a situation where the patient cannot be asked, or more correctly, cannot answer. This may be because the victim is a baby and can’t speak yet, or perhaps the victim is in a coma and is unable to respond to people around h im, but in this case a relative or doctor will decide for the person. It is also important to distinguish the difference between killing someone (Active), and letting them die (Passive). Killing a person is expressed in an action. An example of this, would be a doctor injecting his patient with a poison. Whereas letting someone die, is expressed in not performing an action. An example of this would be a doctor not supplying his patient with drugs that would save his life, and as a result the patient’s life is shortened. I will set, discuss, and finally evaluate a debate about Voluntary Euthanasia using contexts from both the Roman Catholic Church, and the Church of England. Some of the key influences I will refer to are Natural Law, Situation Ethics, Doctrine of Double Effect, The Golden Rule, Church documents, and the Bible. Ignoring all religious views, an argument for Voluntary Euthanasia performed by someone other than the patient, is that it is simply ‘mercy killing’. This would, under general Christian views, be just because it was an act of love, and after all that is what Christianity revolves around. One question, that must be answered is, ‘Is there a difference between killing and letting someone die, when it comes to an argu... ...f the family would suffer as a result of his death, then he should not die in an unnatural way. But, it is more likely that they will be suffering with him, and will feel the relief if he does not, and they do not have to watch him, live any longer in his painful condition. If this is the case, then they should back his feelings, and give him their support. It has been said that although the earth does not belong to the people, God did create humans to make their own decisions on it. Therefore in the case of voluntary euthanasia, there is no doubt that the end decision must be made by the patient, and not the doctor. If the patient is in a persistent vegetative state, then the appeal for his death, falls into the non-voluntary category, and is of no complication to my conclusion. As I have said already, the fifth commandment is addressing the point of murdering innocent people. Murder is when one person intentionally kills another without legal justification or excuse. If euthanasia was legalised, then it would not officially be murder. In such a case, a Christian would not be violating the fifth commandment, and there would be no reason why he could not be a supporter.

germany Essay -- essays research papers

Germany is a country located in Central Europe, which is officially named the Federal Republic of Germany (Bundesrepublik Deutschland). On October 3, 1990 Germany's East and West became one nation under unification, the capital city now being Berlin. Germany has the second largest population in Europe with eighty two million, next to that of the Soviet Union. Germany's land borders are with Denmark on the north, the Netherlands, Belgium, Luxemborg, and France on the west, Switzerland and Austria on the south, and Czechoslovakia and Poland on the east and southeast. The present leader of Germany is Chancellor Gerhard Schroeder, who was elected October 27, 1998 and is now serving his second term in office. Germany's currency is the "Euro," which is a common currency among twelve other European nations. Germany's flag consists of three equal horozontal strips of black, red, and gold. The flag symbolizes German unity. Germans believe the colors in the flag have a meaning, blac k represents "out of the darkness," red represents "through blood", and finally gold which represents "into sunshine." The flag was adopted in 1990 when East and West Germany unified. Major German cities include: Berlin (3.4 million), Hamburg (1.7 million), MÃ ¼nchen (Munich)(1.2 million), KÃ ¤ln(Cologne)(964,000), Frankfurt, Essen, DÃ ¼sseldorf, Stuttgart, Dresden, Hanover, and Bonh. All these major cities have a wonderful cultural history; consisting of over two-hundred theatres and opera houses, one-hundred large orchestras, and more than two-thousand museums amongst them. Most of the cultural ongoings in Germany are financed by the state and local governments. Music plays an important role in Germany's culture with such well-known artists as: Johann Sebastian Bach, Georger Frederick Handel, Wolfgang Amadeus Mozart, Ludwig von Beethoven, Felix Mendelssohn, and Franz Schubert. Germans take great pride in the long list of great people who made music famous both in Germany and around the world. German people also enjoy sports and recreation; the most popular of which is soccer called Fussball. A favorite winter sport is skiing. Germany consists of four major land regions: the Northern Plains, the Central Highlands, the Alpine Foothills, and the Rhine River Valley. Ma... ...school (Gymnasium). Students who finish secondary school usually become apprentices for three years, so they can learn a trade. There are one-hundred ninety five universities, and other institutions of higher learning in Germany, as well as, more than twenty five art and music academies. The 2003 literary rate in Germany was 99%; therefore, proving a highly successful educational system. Germany has an extensive system of social security and welfare. It covers old-age pensions, unemployment (2005 unemployment rate is 4.8 million), sickness benefits, allowences for injury, rent, and child care, as well as, grants for education and job training. About one-third of Germany's gross national product is spent on social security. Germany also suffers from a housing shortage, and rents remain high.Most people live in apartnments, while few people own homes, since land is very expensive. Germany is a strong force in Europe, which has many good cultural, educational, and social ideas. The United States and Germany have maintained a good relationship over the years, and hopefully will continue to do so.

Abstract This document consists of a comprehensive steel girder bridge design example, with instructional commentary based on the AASHTO LRFD Bridge Design Specifications (Second Edition, 1998, including interims for 1999 through 2002). The design example and commentary are intended to serve as a guide to aid bridge design engineers with the implementation of the AASHTO LRFD Bridge Design Specifications, and is offered in both US Customary Units and Standard International Units.This project includes a detailed outline and a series of flowcharts that serve as the basis for the design example. The design example includes detailed design computations for the following bridge features: concrete deck, steel plate girder, bolted field splice, shear connectors, bearing stiffeners, welded connections, elastomeric bearing, cantilever abutment and wingwall, hammerhead pier, and pile foundations. To make this reference user-friendly, the numbers and titles of the design steps are consistent between the detailed outline, the flowcharts, and the design example.In addition to design computations, the design example also includes many tables and figures to illustrate the various design procedures and many AASHTO references. AASHTO references are presented in a de dicated column in the right margin of each page, immediately adjacent to the corresponding design procedure. The design example also includes commentary to explain the design logic in a user-friendly way. Additionally, tip boxes are used throughout the design example computations to present useful information, common practices, and rules of thumb for the bridge designer.Tips do not explain what must be done based on the design specifications; rather, they present suggested alternatives for the designer to consider. A figure is generally provided at the end of each design step, summarizing the design results for that particular bridge element. The analysis that served as the basis for this design example was performed using the AASHTO Opis software. A sample input file and selected excerpts from the corresponding output file are included in this document. 17. Key Words 18.
