History Of The Food And Beverage Management Marketing Essay

History Of The Food And Beverage Management Marketing Essay In this modern age, people dine out for pure enjoyment, to escape from their daily routine, to experience different styles of cuisine and the service the restaurants offer. When going to a restaurant, customers pay attention to the location it is sited in. When choosing a restaurant, customers pay attention to their surroundings and they consider if it is a good area, if it accessible, if it offers car parking or if it is close to a station and if it is suitable for disabled people. Customer that would dine in a restaurant expects warm ambience, high standard service, good customer care and exceedingly good quality food. From the restaurants point of view there are many more aspects to pay detailed attention to, such as: The type of market it is serving, their customer profile, strengths and weaknesses of the operation, Menu, staffing, resources, merchandising, promotions, issues on the macro environment that would effect the business, attention to their competitors, opportunities to improve the business and the threats that could be harmful to the business and the actions to take against it. This report is on the analysis of Boxwood Cafe in Knightsbridge. The reason that this restaurant has been taken in consideration is because there are many fans of Gordon Ramsay. Gordon Ramsay is known for his high level of attention to detail and his high standards of service, which attracts this report to investigate the management of this restaurant. Having said this, it was a struggle to reach the manager of Boxwood Cafe in such a busy environment. It was only possible to gain information on Boxwood Cafe, electronically, with a questionnaire answered by Angela Downes, the operations manager of Gordon Ramsay Holdings. Most of the questions were answered, however, a certain amount was considered to be strictly confidential as she quoted: We do not divulge this information. The amount of questions answered were six out of eleven, leaving out questions about the customers profile, their SWOT analysis of the Menu, questions on staff problems and staff challenges and what their external threats would be. Would you name any four challenges within the management? Angela Downes quotes: We do not divulge this information, which again this shows the secretive nature of the company. Company Information and Location Company information Opened in 2003: Gordon opened the uniquely styled Boxwood Cafà © at The Berkeley, Head Chef Stuart Gillies creates an inspired seasonal menu with emphasis on British ingredients presented with daily market specials Owned by Gordon Ramsay Holdings Ltd Executive chef: Stuart Gilles: Stuarts passion and contagious drive was captured by Gordon who immediately offered Stuart the reins to this innovative restaurant concept. Stuart transcended old classic French dishes into modern Italian at The Connaught. His influences at this time also reflected a year spent in Rome at the Lord Byron Hotel and 3 years in Stockholm, Sweden. Manager: Joeness Amara-Bangali: Joeness Amara-Bangali joined Stuart Gillies and the Boxwood team in January 2005 to manage the busy restaurant and Private Dining room. Previous to this, he was Restaurant Manager at Sugar Reef from July 2001 to December 2004. His approach to service has maintained the informal style that Boxwood has perfected, whilst providing guests with a vibrant atmosphere and fun dining experience. Location The Berkeley, Knightsbridge LONDON: 5 star luxury and  contemporary chic hotel in Knightsbridge Hotels and fashion Brands around the area: Mandarine Oriental, Sheraton Park Tower, Carlton Tower, Lowndes Hotel are the 5 star Hotels we can find in Knightsbridge. Sheraton Belgravia, Rembrandt Hotel, Claverely on Beaufort Gardens, Franklin Hotel and Millennium Knightsbridge are the 4 star hotels situated in this area. The hotels situated around the restaurant are http://widget.criteo.com/sendEvwi=7709106pt1=2i1=181858The Lanesborough, Intercontinental London Park Lane, The Halkin , The Berkeley, The Metropolitan, The Athenaeum, The Park Lane Hotel, The Jumeirah Lowndes Hotel and many more that are luxurious and on top of the class. Hyde Park: Hyde Park is literally across the road from the restaurant and is an attraction to every local and tourist. Thanks to the green surrounding it offers and many water facilities, it is an attraction and relaxing park. Department stores: Harrods, Harvey Nichols: Harrods is one of the main tourist attractions in Knightsbridge thanks to the luxurious variety of products it offers and with their seasonal themes and events in the store. It creates an attractive atmosphere to the customer. Harvey Nichols, another department store in Knightsbridge ,offers another type of atmosphere which is considered modern that would target a younger generation. Competiton:100 restaurants in Knightsbridge (approximately): The restaurants sited in Knightsbridge would include big restaurant chains such as Wagamama, Yo-Sushi , Cafà © Rouge and etc. To mention the restaurants within Harrods,such as The Georgian Restaurant, The Terrace Bar, Caffà © Florian , Planet Harrods, Dim Sum, The Veuve Clicquot Champagne Bar, The Green Man Pub, Sushi Bar or the Fifth Floor restaurant in Harvey Nichols are more convenient for the customer but would make it harder for Boxwood Cafe to attract the customer. The other direct competition would be the opening of Marcus Wareings restaurant at The Berkeley. As we all know Marcus Wareing was in business with Gordon Ramsay and was a chef patron of Petrus and The Savoy Grill of Gordon Ramsay holdings. After separating and parting from Ramsay holdings Ltd, Wareing opened a restaurant at The Berkeley which hosts Boxwood Cafà © as well. The conclusion is that they know each others operation strategies which may create a direct competition. Customer Profile Demographic Profile Age: 28-50 Gender: Male and Female Occupation: Skilled Workers Salary : £120,000 and over, after tax Lifestyle: Cash rich, Time rich(customers which have the money and time to spend) Geographic Segmentation Local, regional and International customer Psychographic segmentation Smart-Casual social groups: People who would escape from the lag of the highly busy Knightsbridge. Strength, Weaknesses, Opportunities and Threats Strengths Situated in a high class area Owned by a celebrity chefs company: which has its own publicity and would attract customers to have an experience the food that Gordon Ramsay proudly recommends. Accessible Environmentalists Exceedingly good customer care Friendly Staff British Menu Large variety of choice on the Menu Excellence of training staff Weaknesses Price of alcohol very expensive Staff is not aware of the dish served in front of the customer e.g. Blue meat served to customer that requested medium and customer that requested blue was served medium. Too many waiters serving one same table Low advertising Macro-Environment Analyzing the restaurant, we identify the PEST, Political, Economical and Socio-cultural, technological. Politics: (Food Standard Agency, http://www.food.gov.uk/foodindustry, 2009) Regulation (EC) 852/2004 on the hygiene of foodstuffs Regulation (EC) 853/2004 laying down specific hygiene rules for food of animal origin Regulation (EC) 854/2004 laying down specific rules for the organisation of official controls on products of animal origin intended for human consumption The legislation: modernised, consolidated and simplified the previous EU food hygiene legislation applies effective and proportionate controls throughout the food chain, from primary production to sale or supply to the final consumer (from farm to fork) focuses controls on what is necessary for public health protection clarifies that it is the primary responsibility of food business operators to produce food safety Economic: The Credit crunch Gas prices going up Electricity prices Socio-cultural: the evolving of age of the population and the consequences it will have on the market Technological: as technology improves in the industry for equipment used in kitchens, the skills required will decrease, time will be spared, labour costs will be cut down. Opportunities: They can improve their weaknesses as mentioned above Threats: would be the direct competitions that are situated around the area and as mentioned earlier on there are a lot of competing restaurants (approximately 100 according to www.allinlondon.co.uk, 2009) The Menu According to Foskett One approach to sale analysis, which had gained popularity is the technique known as menu engineering. This is a technique of menu analysis that uses two key factors of performance in sales of individual menu items: The popularity and Gross Profit cash contribution of each item. There are four types of categorizations in menu engineering. Items of high popularity and high GP contribution. These are known as stars. Items of high popularity, low GP contribution. These are known as plowhorses. Items of low popularity, high GP contribution. These are known as puzzles on the menu. Items of low popularity, low cash GP contribution. These are known as the worst items on the menu and are known as dogs. Type of Menu Modern British Produce based on seasonality Best selling dish: Grilled Aberdeen Angus rib-eye chop Set lunch  £25 per head A la carte  £50 per head(average) Menu changed frequently Managerial analysis Average spend per head  £50 Average cover daily: 205 Monthly income: around  £310.000 Cover Capacity: 120 Keeping customers loyal Advertisement: Internet Sites. Keeping customers loyal: Voucher cards, phone numbers and e-mails Exceeding customer expectations and Providing high standards of cuisine Recommendations staff should be more attentive to the needs of the customer it is better to keep one waiter serving the table, to reduce the confusion of mixing orders of customers specific requests get rid of the dogs on the menu In order to boost sales, the restaurant must advertise more To keep track of Customers and their details, restaurant could use reward cards.

Future scope means that what enhancement can be done in the future. Section 6.1 covers the Conclusion and Section 6.2 covers the Future scope. 6.1 CONCLUSION Web personalization is an answer for data over-burden issue on World Wide Web .The web personalization assemble the accuracy of web hunt apparatus, streamlines the looking process and reduce the time customer needs to spend for looking for. Today for both Web-based affiliations and for the end customers the web personalization has transformed into a key gadget. Web utilization mining is the methodology of recognizing delegate patterns and scanning examples depicting the movement in the site, by investigating the clients conduct. Site directors can then use this information to redesign or change the site according to the side interests and behaviour of its visitors, or upgrade the execution of their systems. Also, the supervisors of e-trade destinations can procure profitable business brainpower, making buyer profiles and accomplishing business sector division. There exists number of techniques yet none has been accomplished great amount. This postulation introduced a methodology taking into account neural system for web personalization of web substance. Firstly, in the pre-processing stage the information must be gathered from the better places it is put away (customer side, server side, and intermediary servers). In the wake of recognizing the customers, the snap surges of each customer must be part into sessions. The last venture of the entire web utilization mining methodology is to dissect the examples found amid the example disclosure step. Web Usage Mining attempt to comprehend the examples identified in before step. The most well-known systems is information visualization applying channels High dimensional information stream contains a huge colossal measure of information. Such huge sum information contains a vast information with high measurements with information many-sided quality. A valid example remote sensor framework data, web logs, Google look for, et cetera. Standard strategies are not suitable over h igh dimensional data as they obliged high figuring expense for taking care of data that is the reason this technique has been realized with some change highlights. 6.2 FUTURE SCOPE Future misleads examine the half breed utilization structure positioning that can be connected to a bound together web/navigational diagram which extends out of the breaking points of a solitary site. Such approach would empower a worldwide significance positioning over the web, improving both web query items and the suggestion process. Now, if the user wants to revisit URL P3, she would not be able to do that using just the BackButton navigation Stack. If she resorts to the history list to get some help, she will be disappointed to see that its list based textual representation gives no idea about the structure of the navigation pattern. Moreover, even for a modestly sized navigation session, the history list gets cluttered to an extent so that renders it ineffective in searching for a specific page. The bookmark facility is of little help in this case, as the user cannot bookmark each and every page due to overhead associated with the very process of bookmarking. Moreover, even selected bookmarking is of no help as, in most cases, the user does not know at the time of visiting a web page whether it is important enough to be bookmarked. One thing that has long been acknowledged by the research community is the use of graphical overview diagrams in assisting user navigation through complex information spaces. The visualization scheme employed should be efficient enough to give a graphical representation of user session history in real time. Computationally and graphically intensive application may cause undue delays in the visualization generation process, especially when the session history grows large. Most of the past work done for WWW subspace visualization is plagued by these delays therefore is inefficient for the ordinary use. The solution must be designed keeping in mind that it has to replace WWW browser stack based navigation structure and its history list. Therefore it must provide all those facilities that were provided by these browser components. Users who are familiar with the facilities provided by the browser may find it very difficult to adjust to a new scheme that does not provide these facilities. The visualization scheme should be designed more on an aesthetic rather than a scientific basis. Humans tend to get confused when presented with a large amount of data jumbled up in front of them. It is, therefore, highly recommended that session history data be divided into small and easily manageable groups, neatly knitted together through an elegant link structure. 1

Concept Analysis on Self Perception Essay -- Psychology

This is a concept analysis on self-perception. Self-perception is non-discriminatory in that it crosses all socio-economic, religious and ethnic backgrounds. The effects of self-perception can be and usually are life altering. Self-perception can tear at the fabric of the victim's self-confidence, self-worth and trust in their perceptions when relating to life events, eventually causing a chasm or warped view of the inner self. The reason for examining self-perception relates to how it affects the healing process and the relationships with those providing care. Introduction Working in a healthcare system you encounter people from various ages and statuses. It has always been concerning to see how self-perception affects a person’s wellbeing. Understanding self-perception is to also understand how people change both internally and externally depending on the perception that they have of themselves and how professionals in the healthcare field can help to mend that self-perception. The long term effects of self-perception are both psychological and physiological and play a direct role in the healing process. Purpose The purpose of this concept analysis is to (1) understand self-perception (2) define and understand the critical attributes within the framework of nursing, philosophy, society and psychology (3) consider the long term effects of self-perception. To fully understand self-perception we must first understand how it is defined. The following definitions and explanations of the word ‘self-perception’ come from The American Heritage Dictionary of the English Language 5th Edition. Self-perception is defined as an awareness of the characteristics that constitute one’s self; self-knowledge. Self-Perception is ve... ...self running low on self-esteem. (1995, November-December).

Ernest Hemingway, World War I, and Agnes von Kurowsky :: Biography Biographies Essays

Hemingway, World War I, and Agnes von Kurowsky Hemingway's World War I experiences were the source of much of the legend that later surrounded him. Brave and masculine, he was the writer who really got out there and experienced everything. Wounded in the trenches, decorated for his valour, he then threw himself into a wartime romance with the nurse who was responsible for bringing him back to health, his first love, who later jilted him for an older, aristocratic, man. This report will examine the background to these myths and assess their veracity. It was not long after the United States declared war on Germany in April 1917 that 17 year-old Hemingway, not yet finished high school, first expressed an interest in seeing some action. However his father, keen for him to follow his sister to college, settled for a compromise that saw his brother fix young Ernest up with a job in the Kansas City Star. That November, he told his family that he could not possibly wait more than another year before enlisting, saying "it will be hard enough to stay out until then". Biographer Kenneth S. Lynn argues that for the young Hemingway, the war was like a championship football game, a huge event not to be missed.1 Hemingway's letters of that winter contain references to him attempting to join the army but being refused because of a bad eye. Nobody has been able to find any evidence that such a claim is true. Lynn points to the likely falsity of the claim by mentioning the fact that Harry Truman, who was helpless without his glasses, got past the same army doctors in Kansas City that Hemingway would have had to deal with, and suggests that the prospect of squalor and danger in the trenches did not accord with Hemingway's vision of the great event of his time. At the same time, his reading of Hugh Walpole's The Dark Forest the previous year made him aware of another, heroic, and far less dangerous way of seeing the war - the Red Cross. Ernest and his friend Ted Brumback volunteered for the Red Cross in early January and in April they were assigned as second lieutenants in an ambulance unit in Italy. They were issued a regular US Army officer's uniform with full insignia, and Ernest made the most of the fact that real army privates and non-commissioned officers had to salute him, in one instance counting 367 salutes as he walked up and down Broadway.

The Usage Of A Bandgap Reference Voltage Engineering Essay

A bandgap mention electromotive force is an indispensable constituent of an parallel to digital converter.It is frequently used to provide a mention electromotive force which is compared with others voltages.The bandgap mention used in diverse applications is based on the thought of Hilbiler in 1964 [ 1 ] aˆ‚A bandgap mention electromotive force with low sensitiveness to temperature and supply electromotive force is normally required in parallel or digital circuits. Low electromotive force and low power are two of import design standards in both parallel and digital systems.It been expected that the whole electronics system will be operated down to a individual 1-V supply in near future.The bandgap mention ( BGR ) generators which can be operated under 1-V supply have been widely used in DRAM, falsh memories, analog-digital convertor ( ADC ) and assorted parallel devices.So far many techniques have been proposed to develop electromotive force or current mentions, which can be about independent to temperature and power supply voltage.The bandgap mention is the major design to supply a preciseness electromotive force mention with low sensitiveness to the temperature and the power supply.when CMOS engineerings enter the nano-scale epoch, The demand for battery operated portable equipments will increase.the supply electromotive force has been scaled down from 1.8V ( in 0.18 µm engineering ) to 1.2V ( in 0.13 µm engineering ) , and will drop to merely 0.9V in the following coevals engineering [ 2 ] .In CMOS engineering, the parasitic perpendicular bipolar junction ( BJT ) had been normally used to implement P-N junction of the bandgap reference.But the traditional CMOS bandgap mention circuits did non work in sub 1-V supply voltage.the ground, that the minimal supply electromotive force can non be lower than 1V is constrained by two factors, which is the bandgap electromotive force of around 1.25V in Si, which is exceeds 1V supply.The others factor is the low-tension design of the relative to absolute temperature current coevals cringle is limited by input common-mode electromotive force of the amplifier.These two limitions can be solved by utilizing the resistive subdivision methods, low threshold electromotive force ( or indigen ) device, BiCMOS procedure or DTMOS device.However, those attacks frequently require specialised procedure and word picture which addition fiction cost and procedure stairss. Reference electromotive force generators are required to be stabilized over procedure, electromotive force and temperature fluctuations and besides implemented without alteration of fiction process.The bandgap mention ( BGR ) is one of the most popular mention electromotive force generators that successfully achieve the requirements.regarding the generators, the demand for the low power and low electromotive force operation is strongly increasing the spread of the battery-operated portable applications.A bandgap mention electromotive force is an indispensable constituent of an analog-to-digital converterIt is frequently used to provide a mention electromotive force which is compared with others voltage. A bandgap mention electromotive force with low sensitiveness to temperature and supply electromotive force is normally required in parallel or digital circuits.there are several methods to recognize a temperature independent voltage.the base emitter junction used as a nucleus constitu ent of the bandgap mention is the most popular approach.the general bandgap mention electromotive force mention electromotive force is described by a additive combination of base-emitter electromotive force. Bandgap mention circuit is widely used to supply stable current and electromotive force mentions in parallel circuits every bit good as in assorted signal CMOS circuits.A stable mention circuit should be robust against temperature, power supply and procedure variations.Sub-1-V mention coevals has got importance due to scaling ensuing in shrinking of MOS dimensions and decrease of power supply to minimise power ingestion. owing to follow Moore ‘s Law, it has become needfully of import to diminish the power in the chip.This puts the restraint on the power dissipation of mention generators.the design of this bandgap besides see for low power operation..In traditional BGR circuit, bipolar transistors and one or more resistances are used.BJTs that are used in BGR are in parasitic signifier in CMOS.resistor occupy big country on the bit and hence addition the cost.on bit tolerance of resistances vary from 20 % to 30 % .So, we have to replaced these constituents with MOS transistors t o better public presentation of BGR and to salvage bit area.The combination of different runing parts like subthreshold, additive and impregnation of MOS suppresses the temperature dependance of electromotive force mention.Aims:To set up a dc electromotive force or current that is independent of the supply and procedure and has a chiseled behaviour with temperature. To plan the BGR that independently to temperature and low noise and low electromotive force To plan bandgap mention that can be successfully operated with sub 1-V supply in standard 0.35 CMOS procedure without particular procedure engineering.Problem statementWhen CMOS technologies enter the nano-scales epoch, the demand for battery-operated portable equipments will increase.The supply electromotive force has been scaled down from 1.8V ( in 0.18 m engineering ) to 1.2V ( in 0.13 engineering ) and will drop to merely 0.9V in the following engineering [ 2 ] .in CMOS engineering, the parasitic perpendicular bipolar junction transistor ( BJT ) had been used to implement the high preciseness bandgap electromotive force references.However, the convential BGR generates a 1.25V mention voltage.Its fixed end product electromotive force limited the supply electromotive force and non suited for sub 1-V supply volateg operation.The ground why the conventional CMOS bandgap mention did non work in close 1-V supply voltage.One is that the bandgap end product electromotive force is about 1 .25V [ 3 ] , which exceeds 1-V supply.The others is that the low temperature electromotive force design of the relative to absolute temperature current coevals cringle is limited by the input common-mode electromotive force of the amplifier.These two restrictions can be solved by utilizing the resistive subdivision method [ 4 ] , low threshold electromotive force device [ 5 ] , BiCMOS procedure or DTMOST [ 6 ] . But, those attacks frequently require specialised procedure and word picture which can increase fiction cost and procedure step.However, the bandgap mention working in low supply electromotive force has a higher temperature coeeficient than that of traditional bandgap reference.This resulted in the development of new temperature compensated techniques such as quadratic temperature compensation [ 7 ] , exponential temperature compensation [ 8 ] , piecewise additive curvature rectification [ 9 ] and resistance temperature compensation [ 10 ] .To implement these advanced mathem atical maps with high truth, the development of the low electromotive force bandgap construction requires precision matching of current mirrors or a pre-regulated supply electromotive force, cascade current mirror [ 11 ] , and pre-regulated circuit are good methods to work out this problem.but the minimal supply electromotive force is tradeoff.Scope of work:A typical CMOS execution of a bandgap mention is shown in Fig. 1. The end product mention electromotive force VREF of the traditional bandgap mention circuit can be written as: Equation 1 trad bgr.bmp Figure 1: Traditional/conventional BGR circuit in CMOS engineering where A1 and A2 is the emitter countries of Q1 and Q2, and VT is thermic electromotive force. The 2nd term in ( 1 ) is relative to the absolute temperature ( PTAT ) , which is used to call off the negative temperature coefficient of VEB. Hence, if a proper ration of resistances is kept, an end product electromotive force with lowsensitivity to the temperature can be obtained. In general, the VREF is about 1.25 V, so that the conventional bandgap mention circuit can non be used in low electromotive force application, such as 1 V. Mention electromotive forces and/or currents with small dependance to temperature turn out utile in many parallel circuits. As many procedure parametric quantities vary with temperature, if a mention is temperature-independent, it is normally processindependent every bit good. If two measures with opposite temperature coefficient are added with proper weighting, the attendant measure theoretically exhibits zero temperature coefficient. The construct of the new proposed bandgap mention is that the two electromotive forces ( which are relative to VEB and VT ) are generated by merely one feedback cringle. The two-stage operational amplifier with p-channel input is used in thisnew proposed bandgap mention. The new proposed bandgap mention is shown in Fig. 2, which uses the resistive subdivision R1a, R1b, R2a and R2b to cut down the input common-mode electromotive force of the amplifier.The dimensions of PMOS devices M1 and M2 are the same.The opposition of R1a and R2a is the same, and th e resistanceof R1b and R2b is the same. Following the KCL at the nodesof V1 and V2 in Fig. 2, the mention electromotive force can be expressed as New Picture.bmp Equation 2 Where and.According to equation below: ) /R4 We can expressed equation 2.The point of Vref-conv is indistinguishable to the conventional mention electromotive force in equation ( 1 ) .In order to accomplish sub 1-V operation, the ratio of R1b/ ( R1a+R1b ) is used to scale down the mention electromotive force level.Therefore, the minimal supply electromotive force of the new proposed BGR can be efficaciously reduced to merely. The new proposed BGR mentions can operated under bomber 1V.The whole complete circuit to recognize the proposed bomber 1V BGR is shown below: New Picture ( 1 ) .bmp Figure 2: Complete circuit for new proposed Sub1V So, from the comparing above, I can clearly cognize what I will make on my ain undertaking, what my range of work.From this, i ‘ll go on the new proposed BGR design that already done but I will seek to minimise the supply electromotive force, temperature independent and noise consequence as possible so the BGR will successfully operated in sub 1-V.

Thao Nguyen02/18/2013 Toefl Prep. Dr. Ray Simple Essay Problem solving is the most important skill in the present day world. We have to deal with problem solving in business, in private lives, and in doing everyday choice. Below, I would like to specify the importance of this most vital skill in the areas mentioned above. First, every business is based on the ability of the owner of the business and his employees to make fast and professional decision.There are many situations in business that may be connected to buying a new product, selling it to the right person, advertising it, or communicating with other businesses for the sake of promoting your own. For example, my friend has a small restaurant. I can see how hectic his life is most of all, I am surprised at the speed with he makes very important decision. Sometimes, these decisions are wrong, but he does not mind. He says he his learning from his mistakes. Obviously, it is absolutely essential to solve the problem in business quickly if you want to survive in a tough competition in present day world.Second, we have to make a lot of personal choices in life, and therefore, we have to learn how to solve a lot of personal problems, too. It is a very difficult thing to make the right decision in love situation. I, for one, am very an emotional person. Due to my emotions, I make quick but wrong decisions. Therefore, I blame myself afterwards for having done or said something without much thinking. I know that I have to work on my ability to think first and to act after that if I want to be successful in problem solving.Third, my life is full of chores. I have to run around doing things, connected with my job, my college work, and my personal duties. For an instance, I have to make decisions every second, what to buy, what to wear, what to say, and how much money to spend. In fact, if I do not solve this problem quickly, I am lost. In conclusion, every one of us needs to do a lot of problem solving every day. We should be smart and calm about our decisions. I hope I will acquire this skill as I am moving along in life. The choice we make dictate the life we live.

Ethical Scrapbook

In any profession unethical behavior can be present, it is ultimately up to the individuals. They have to decide what is ethically right and not take short cuts or engage in unethical behavior. The banking profession, such as bank tellers, is exposed to large amounts of money. They can choose to be ethical and not attempt to steal from their clients, or they can act unethically by choosing to steal money. Another profession is research, there are conditions that exist for unethical behavior. When researchers conduct experiments, they usually write a report about their results.If the results do not go in the direction that they wanted them to, this gives the researchers an opportunity to act unethically. They can either choose to act ethically, and report the true results from the experiment, or they can choose to act unethically, and report the results in a manner that will benefit them. â€Å"In the process of making decisions regarding their professional behavior, psychologists mu st consider this Ethics Code in addition to applicable laws and psychology board regulations.In applying the Ethics Code to their professional work, psychologists may consider other materials and guidelines that have been adopted or endorsed by scientific and professional psychological organizations and the dictates of their own conscience, as well as consult with others within the field. If this Ethics Code establishes a higher standard of conduct than is required by law, psychologists must meet the higher ethical standard.If psychologists’ ethical responsibilities conflict with law, regulations or other governing legal authority, psychologists make known their commitment to this Ethics Code and take steps to resolve the conflict in a responsible manner in keeping with basic principles of human rights† (American Psychological Association, 2014). Another profession is professional sports, the athlete could take enhancement drugs to improve themselves at the sport, like taking steroids which is also against the law.Most athletes choose to  do what is ethical and stay away from drugs to ensure that they keep their jobs and the respect of their fans. In medical professions, doctors could take the unethical route and give their patients their drug of choice just to satisfy them, but doctors that admire what they do will be ethical and give the patient what they need and get them help if they are showing signs of drug abuse. â€Å"Within the patient-physician relationship, a physician is ethically required to use sound medical judgment, holding the best interests of the patient as paramount† (The Patient-Physician Relationship, 2001).Pharmaceutical companies are a profession that also has to choose to be ethical or unethical. The individuals that work for pharmaceutical companies are tempted to take medication for their own use. They may steal medications to sell them to make money for themselves. Politics also can contribute to ethical or une thical behavior. If politicians do not like something, they try to hide it from Americans, or they may not tell the whole truth of certain facts. Politicians are famous for covering all of the facts up.
