Connections - Essay Example Generally, protests are carried out against immoral and unjust actions. If protests are violent, they could be immoral themselves or a source of injustice. Therefore, they will not be effective because they are like the very thing that they are protesting against. Due to this, non-violent protests are more effective than violent protests. The first historical example which comes to mind is the British colonialism of the United States. The Americans could not peacefully protest against this because the British had an army behind them and violently opposed any protests to their presence in the United States. Therefore, the only form of protest which could achieve the removal of the British from America was violence. The second historical example which comes to mind is the secession of the Confederate States. The North and all Americans who opposed the division of their country into two could not protest against this in a non-violent way. The confederate states had gathered their armies and had declared their secession from the United States of America. The only way that this development could be reversed was through violence, which means that protest had to take the form of military confrontation. The type of direct action which martin Luther King called for was peaceful protest in the form of sit-ins and marches.

Main Stages Involved In Capacity Management Tourism Essay

Main Stages Involved In Capacity Management Tourism Essay Capacity management in the tourism industry is measured by the available seat-miles per month. Capacity management is an important factor within hospitality operations as it tests activity for the manager and therefore gives them an indication of the maximum level of value-added over a period of time, so they can see what the operation could achieve in normal conditions. According to Armistead and Clark (1994, p6) Capacity management is the ability to balance demand from customers and the capability of the service delivery system to satisfy the demand. This places an emphasis on understanding first, the nature of demand by forecasting and second, the options for managing capacity to meet the expected demand. The process consists of forecasting and managing capacity, these are made up from smaller components which will be discussed in further details in this report. 2. Forecasting Forecasting is used to identify capacity gaps between product demand and the current capacity. It is an important process in all management decisions not just tourism management; although each situation is different you can apply the same procedures to make realistic capacity decisions within any business. Forecasting methods can be divided into qualitative and quantitative categories which are based on the availability of historical time series data. Establishing the level of demand when forecasting is of the upmost importance as failure to do so can cause over booking and overcrowding. Other eventualities from inaccuracy of forecasting can include incorrect numbers for staff and lack aircrafts which was one of the factors which effected American airlines development in 1990 (Krajewski and Ritzman, p275) . It helps to understand product life cycle as it will impact the capacity. It is also important for a manager to look at external factors such as trends as they will have an effect on the supply and demand of a product or service, these can include; Ageing population- this will affect the quantitative forecasting as our current population is living longer, so you cant use historical data to establish relationships as its continuously changing. Seasonal trends- They can depend social, economic and environmental impacts. This would be best measure by qualitative forecasting. Disposable income- Due to the recession people will have less disposable income. 2.1 Forecasting Techniques There are various different forecasting techniques that cover various timescales, the two most common techniques are: Long-term capacity management For large projects Usually planned over several years In tourism this will involve several departments Short-term capacity management Plan and order resources Usually a monthly, weekly or daily basis Tourism short term capacity management would involve the cleaning of an aircraft Long term planning requires demand forecasts for an extended period of time, the decisions made are often concerned with strategic decisions to ensure achievement of their desired objectives. Short-term capacity management focuses on relatively small time durations and specific processes; they are specifically for smaller levels of operation. Unfortunately, forecast accuracy declines as the forecasting time lengthens. Forecasts also dont allow for competitors actions however waiting line models and decision trees do. 3. Types of forecasting Forecasting methods can be divided into two broad approaches, these are; Qualitative Quantitative The majority of forecasting techniques use past or historical data in the form of time series. One single method is never used on its own as they are both usually interlinked. 3.1Qualitative Forecasting The Qualitative method generally uses the judgment of experts in the appropriate field to generate forecasts. An advantage of this is that experts can generate a forecast if there isnt any historical data available. The main challenge to qualitative data analysis is that there is no clear and accepted set of conventions for analysis corresponding to those observed with quantitative data (Robson, 1993, p.370). The most popular methods of qualitative forecasting are: Delphi technique Scenario writing Subject approach Expert opinion Life cycle analysis 3.2 Quantitative forecasting The Quantitative methods use historical data; the methods consist of analyzing historical data concerning the time series of the particular variable of interest and other time series if they interlink with the area concerned. There are two main methods used within quantitative forecasting, the first method bases the future forecast on a past trends, these are known as time series methods. The second method also uses historical data. But the forecaster examines the cause and effect relationships of the variable with other relevant variables such as; Disposable income Interest rate Unemployment rate The state of the economy e.g. the recession This type of forecasting uses past time series, forecasting techniques that are under this category are called casual methods. 4. Capacity management After deciding what products and services should be on offered, management should then plan the systems capacity. The first step in the Capacity Management process, forecasting, is the best way to judge attendance and understand product life cycle. Therefore Capacity Management itself is used to make sure the capacity, from a tourism managers point of view, meets the targets set. The capacity of an airline usually depends on the location and the available seats per miles, as well as staff, time and other resources which are used. 4.1 Measuring Capacity According to (Krajewski and Ritzman, p276) No single capacity measure is applicable to all types of situations Every manager will have to take other factors into consideration before they measure their capacity. If there is an insufficient capacity it wont be possible to meet all of the demand, therefore to much capacity is provided and this will result in resources not being used to their maximum capability. 4.2 Coping with Demand The need for accurate forecasts of tourism demand to assist managerial decision making is highly important as the tourism product is perishable and if it doesnt meet the demand they lose revenue as an aircraft still has to fly without the demand being met. There are several ways of coping with demand and these are; Keep the activities level of resources constant and ignore any fluctuations. Adjust capacity to match demand. Change the demand to fit the capacity. 4.3 Queuing Theory Queuing theory is important to an as its one of the important factors in meeting their attendees needs. Queues arise when a demand for a service has exceeded the capacity, the customer doesnt get the service straight away upon arrival so they must wait for the service to be ready. This is an important for an airport as they have a random system which customers can arrive at any time; it isnt difficult for an airport to experience queues, but it is important that they deal with them sufficiently. These queues will often build up, disappear in quieter periods and then reappear all the time as there are always flights departing and arriving. Airports offer departing guests waiting rooms and shops to deal with queues and when they arrive they must go through customs which is a slow but easy method for managing the mass amount of people. 4.4 Queue Discipline Most managers will employ a simple queuing method to ensure a positive experience for the customer. These can be; Priority system for certain customers FIFO First In First Out LIFO Last In First Out 5. Conclusion This report has looked at the three main stages involved in capacity management and the different methods available to any manager. Although forecasting isnt always accurate, there is a wide variety of techniques in the first stage which can be used for any method. It is highly important to consider past experience as well as modern trends for more of a refined forecast, failure to do so could lead into an inaccurate forecast. The capacity management stage can then deal with the demand if it is insufficient or too high, then the queuing theory may be taken into consideration. In an airport due to the nature of the business it is unpredictable to measure the amount of customers as people can come and go as they please. This means the queuing theory may or may not make the service time, however if the demand has been manipulated to help predict the expected demand then it will reduce the waiting time and overall give the customer a positive experience. All of the stages combined prepare a tourism manager for any unforeseen outcomes in a tourism service and will allow them to successfully manage any outcome.

Cultural and Racial Inequality in Hemingways Indian Camp Essay

Cultural and Racial Inequality in Hemingway's Indian Camp Hemingway's "Indian Camp" concerns Nick Adams' journey into the unknown to ultimately experience and witness the full cycle of birth and death. Although Nick's experience is a major theme in the story, cultural inequality also is an issue that adds to the the story's narrative range. Throughout this short story, there are many examples of racial domination between Nick's family and the Indians. Dr. Adams' and Uncle George's racist behavior toward the Native Americans are based on the history of competition between Caucasians and America's indigenous peoples. "Indian Camp" begins at the shore where Nick, his father, and Uncle George are picked up by Indians in rowboats. When Nick and the men get into the rowboat, the Indians row them to the Indian Camp, with no help from the doctor or Uncle George. This evidence is the first example of cultural domination in the story. Once across the lake, Uncle George gives the Indians cigars. Uncle George's action could be a gift or a congratulatory gesture for the baby about to be b...

Titanic - Story :: Expository Essays Research Papers

Titanic - Story Hello, my name is Richard Peterson, I am travelling first class, on the Titanic from Ireland, I am moving to New York because I want to make something out of my deep interest in motorcars. I am travelling with my Wife - Mary, Mum - Jean, and brother - John. On the evening of 11th April 1912 at about 11 O'clock I was having a cup of tea with my wife in our cabin when we felt a rather large shudder. We didn't think much of it at the time as we thought that is could have been anything. Room service knocked at my door requesting to take our rubbish, this was when we asked her what the shudder was. She said, "Don't worry, it was only the propeller hitting a small rock, we just stopped the engines to check that they are ok." About a quarter of an hour later a crew member came to our cabin and told us to get our life jackets of and to report up to top deck as soon as possible, this is when both my wife and I started to get a bit worried. As instructed we reported to top deck, but on the way up we were asked the man who made the ship what had happed. He said, "We only have 2 hour at the most, I'm afraid to admit, my ships going to sink." We knew we didn't have much time but enough to easily get on to a lifeboat. So we went back to our cabin and rushed down a cup of tea to stop us from dehydrating as we didn't know how long it would take for another boat to pick us up. Then we went to the restaurant as got some biscuits for us and the other people which would be on our life boat. With only having 1 hour to spare we rushed as quick as we could to the top deck, we looked everywhere but couldn't find a life boat, then when we got to the other side of the deck we found a lifeboat, we cued up for it, we waited about ten minutes until it got to us, then finally we were one of the last four people to get of the lifeboat, we were cramped up, there were forty people on our lifeboat. After about half an hour we were terrified, as we were watching the

Essay --

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

Sculpture and Ralph Hicks

It's a cold and overcast day in February and a man sits alone at a park bench, at the Dotted Sculpture Park. He watches as the river splashes aggressively about, caused by the strong wind blowing that day. Perched above him on the top of a hill just a few feet from the road, sits a large-scale sculpture called â€Å"Salutation†, by Ralph Hicks. Standing only 6 feet tall, it's original conception called for the sculpture to have a height 30 feet and be placed at five of the major entry. Pays leading into Toronto.They would have welcomed visitors entering the city, if Toronto had won the bid for he 2008 Summer Olympics. On the first visit to Salutation, the lack of sun casts a shadow on the face as it bends forward and faces down, displaying a feeling of sadness. Shaped from metal and grey in color, the sculpture seems to reflect a feeling of submissiveness on this dark winter day. Its block-like smooth texture contrasts to the nature surrounding it, but offers balance with its simplistic lines and movement.The large size does not intimidate, but rather holds a lonely tone, reflected by the days weather. The use of lock like pieces allows for a childlike appearance and its rounded corners allow the installation to feel friendly. If the structure had contained sharp corners with a combination of grey color and metal exterior, it would have projected hard lines and been unwelcoming. Though it appears Hicks motive for its location was to greet people as they drove by, I have to question that decision.Salutation is not only misunderstood but also neglected by motorists who do not have the ability to interpret the meaning of the piece. Neither did it receive much attention from the pedestrians walking below. The riverside path is located at the bottom of the hill and by observing a few walking bye, they did not look up towards the sculpture once. The visitors attention seemed to be directed at either the river, the other sculptures, the skyline or themselves. T hus placing more emphasis on the loneliness the piece portrays.Another visit to Salutation with the morning sunrise reflecting upon it, did deliver a more cheerful feel. But the loneliness still lingered from the prior visit and now it's as if it was smiling but still disguising the sadness within, as many go about their days and do. The sculpture with its rhythm of playfulness and kindness, puts a smile on your face if you allowed it to. Salutation has no reference to gender, age or race and in that way it transcends and relates to all. It faces east, as if to greet the morning sun and take on the day.Later as the sun sets behind it with it's head bowing down, one feels a sense of it speaking and silently saying, â€Å"goodbye† and â€Å"well done† at the end of the day or a long Journey. A metaphor for life, from dawn till dusk. The salutation action is an attitude of respectful courtesy, which is conveyed through a human form. Salutation the sculpture by Ralph Hicks , assembled with the simplicity of irregular blocks, conveys a commanding presence and attitude. As it bows its head to passing travelers, Hicks tells us little about the model, providing no indication of race, social class or gender.Salutation is indiscriminating to viewers and offers the same greeting to all. Born in London, England in 1941 Ralph Hicks moved to Toronto at the age of 26. He first developed an interest in sculpture while still a student after seeing large-scale bronze sculptures by Roding, Liaise and Matisse at New Work's Museum of Modern Art. Hicks graduated from the University of Bristol and Harvard Business School and worked in the marketing and management field till 1996, where he then committed full time to his current passion of sculpture art.He works out of a studio he built in Mule Hills, Ontario and spends his summers carving stone outside, and works with other material in the studio during the colder months. Hicks designed art with a variety of material su ch as, soapstone, limestone, wood, bronze, traditional plaster, polished aluminum rod, clay and even whimsical vinyl tubing. A lot of his work is tone carving that requires power tools to do the bulk of the work, but obtaining the final finish is the most time consuming part of the process.Hicks designs large-scale pieces because he feels size has impact and public installations are seen by many people and that's rewarding to him as an artist. He creates sculpture for his own satisfaction, but what makes him happiest, is when he hears how a completed piece makes people feel. With his art he has no rules and that's what makes it exciting to him. Salutation is Art, and Art is Salutation with simple cuboids who gives away little information, acknowledges your presence with a friendly bow and asks nothing in return, but causes a lasting impression.
