Energy Efficiency of a PRO Process

Vitality Efficiency of a PRO Process Presentation The worldwide vitality request is speedily expanding because of quickly extending populace and their improved expectation for everyday comforts. Albeit petroleum derivatives are for the most part adding to satisfying this interest, the utilization has just surpassed the limit of maintainable vitality creation (Efraty, 2013)(Yip et al., 2011). It is regularly asserted that we have enough saves of coal, gas, and oil while the genuine situation is unique. Condition researchers detailed that vitality holds are diminishing with time, which would be lessened inside not many decades (Figure 1). The lifetime of these stores would be expanded somewhat if new supplies can be recognized. Finding new wells is turning out to be more earnestly step by step and on the off chance that it is found, the measures of fills would be fundamentally lower than the ones that have been found in the past1. Figure 1: The patterns of worldwide non-renewable energy sources reserves[1] The rising vitality request and constrained stores of petroleum products have spurred to specialists for investigating choices wellsprings of sustainable power source. Scientists have just found different wellsprings of vitality while wind, sun powered, flowing and biomass have been utilized for practical vitality creation (Straub, Deshmukh, Elimelech, 2015).ã‚â However, costly gear and high establishment cost combined with the lopsided circulation of vitality during the time have kept them from being utilized generally (Sharif, Merdaw, Aryafar, Nicoll, 2014). As of late, a recently rising wellspring of clean vitality called Osmotic force has pulled in much regard for the analyst, which got from saltiness inclinations discovered worldwide where two wellsprings of water with various salinities are accessible close to one another (Y. C. Kim Elimelech, 2013).ã‚â The accessibility and consistency of osmotic force are a lot more noteworthy than the discontinuous renewables like breeze and sun based. Saltiness angle is the distinction in salt focus between two arrangements. The huge measure of vitality discharged from the blending of two arrangements of various salinities and this sum ascends for higher fixation contrast between the arrangements. Little scope examinations have been accomplished for the blending of freshwater and seawater, which announced that 2.6 MW vitality created for a progression of 1m3/s freshwater when blended in with seawater (Veerman, Saakes, Metz, Harmsen, 2009). A few advances are being utilized to gather osmotic force, for example, turn around electrodialysis (RED) (Achilli Childress, 2010) (Yip Elimelech, 2012),ã‚â weight hindered osmosisã‚â (PRO) (Altaee Sharif, 2015)(Thorsen Holt, 2009)(Norman S., 2016), capacitive blending (CAPMIX) (Reuters News Agency, n.d.), and hydrogel blending (J. Kim, Jeong, Park, Shon, Kim, 2015). Among the advances, RED and PRO are further developed and shown at pilot scale and the two proselytes substance potenti al to valuable work by the controlled blending of two arrangements of various salt focus (Achilli Childress, 2010)(Yip Elimelech, 2014). RED is a layer based innovation, which is driven by the Nernst potential, a sign of substance potential distinction. It utilizes a heap of adjusting particle trade films that specifically permits particle penetration over the layers. The net particle transition over the films is changed over straightforwardly to electric flow (Norman S., 2016)(Pattle, 1954). The procedure is effective for power age however monetarily wasteful. The cost costs of accessible RED film is out of range, and late examinations have demonstrated that the cost must be diminished a hundred times to make the innovation reasonable (Post et al., 2010). The improvement of such kind of layers is very tedious and hard to accomplish (Turek Bandura, 2007). Likewise, The activities of the RED procedure is perplexing and exceptionally delicate to the procedure parameters, which requires expand control framework (Altaee Sharif, 2015). The same converse electrodialysis, PRO is additionally a layer based innovation, yet the thing that matters is, PRO uses a solitary salt-dismissing semipermeable film rather than a pile of particle trade layers. It uses the saltiness angle as osmotic force distinction to drive the water saturation over the film from low saltiness feed answer for high saltiness draw arrangement. The extending volume of draw arrangement courses through a hydro-turbine that produces helpful mechanical and electrical works [18][19]. The structure and activities of PRO are a lot more straightforward, and it doesn't rely a lot upon operational parameters aside from working weight of film at draw arrangement side. The ongoing examination shows that PRO can accomplish both more noteworthy efficiencies and force densities than RED and other existing advances [14]. The greater part of the PRO examinations have been centered around the blending of seawater and freshwater, however this blending plan has been seen as unfeasible because of the lower power densities. Analysts concur that more examination is important to evaluate the possibility of procedures dependent on surges of higher saltiness. One of such procedures is the vitality recuperation from desalination units by taking favorable circumstances of the blending of released saline solution and seawater. Another procedure is the blending of seawater with high saltiness created water from oil and flammable gas investigation. Notwithstanding, the fundamental issues of these procedure are concentraion polarization and salt spillage, which limit the PRO execution by diminishing the main impetus over the film. Prior to examinations to build up a feasible PRO procedure for the enormous scope activity, have concentrated on growing superior film and setting up reasonable conditions to augment the v itality yields. A few thermodynamic properties are important to set up fitting conditions to evaluate the exhibition of PRO procedure. The first of them is the Gibbs free vitality of blending since it gives as far as possible to the pole power that is conceivable to recuperate from a blending procedure, which happens at steady temperature and weight. Another property is osmotic weight, which in important to build up working weight at various pieces of the plant. Entropies and enthalpies are expected to assess the mechanical intensity of the revolving gear included. This work exhibits a thermodynamic model to assess every one of them so as to augment the force recuperation from PRO procedure. The Q-electrolattice condition of (EOS), which expands a cross section based liquid model for electrolyte arrangements, is received. The model likewise incorporates as of late created conditions for PRO that thinks about fixation polarization; turn around salt penetrability, and layer fouling to anticipate water and salt transition over the film. What's more, most PRO models depend on arrangements of Na+ and Cl particles just, though, practically speaking, saline water contains different particles notwithstanding these two.ã‚â This work reports recreations of PRO procedures that think about the nearness of numerous particles in arrangements (Na+, K+, Mg2+, Ca2+, Cl-and SO42-). The current model generally utilizes various stages to ascertain osmotic force, power thickness, and motion over the film (for example OLI-programming is utilized to ascertain osmotic force and another program for transition and force thickness), that expansion the chance of getting incorrect worth since all these are between subordinate. Then again, this model continually and precisely decides every one of them by a solitary program. Beginning examinations have been accomplished for freshwater+sewater and seawater+brine frameworks with single-stage PRO arrangement. The anticipated osmotic weight, water motion over the layer and recuperations of mechanical force are in excellent concurrence with trial writing information. This arrangement of results recommends that the Q-electrolattice EOS is a reasonable model for the estimation of thermodynamic properties expected to evaluate the exhibition of PRO plants.ã‚â Now, it is arranging this model for high saltiness arrangements with different stage setups. A techno-financial investigation will be accomplished for the plausibility investigation of PRO procedure actualizing at modern scale. Point and Objectives: The point of this work is to build up a thermoynamic model dependent on Q-electrolattice condition of state for PRO procedure, and execute it to foresee distinctive thermodynamic properties so as to caltulate water and salt transition over the film and force densities. The different targets related with this point are outlined underneath: Actualize Q-electrolattice condition of state for the arrangements of various salts to compute osmotic power and confirm the outcomes with writing test information. Actualize as of late created mass and salt transition conditions, which thought about fixation polarization, turn around salt motion and fouling of layer. Actualize fundamental thermodynamic relations for PRO units to decide entropies and enethalpies precisely. Build up the model for freshwater-seawater framework with single stage design and broadened it for higher saltiness framework with numerous stage setup. Actualize the cost conditions to decide the capital expense for establishment of the PRO units. Writing Review Q-elctrolattice condition of state The elctrolattice condition of state (EOS) was created utilizing a similar approach introduced by Myers et al. (Myers, Sandler, Wood, 2002), in view of the Helmholtz vitality approach. The remaining Helmholtz vitality at a given temperature and volume is determined by the expansion different commitments along a speculative path.ã‚â These commitments comprise of particle dissolvable and dissolvable collaboration over the short range, solvation impacts, and particle cooperations over the long range. The complete procedure is separated into four stages along a thermodynamic way( a. Zuber et al., 2013): Step-1: It is accepted that a reference blend comprising of charged particles and atoms is in a theoretical perfect gas state at temperature T and volume V. In the initial step, the c

Representativeness Heuristic and Our Judgments

While this shortcut can speed up the decision-making process, it can also lead to poor choices and stereotypes. Take a closer look at what the representativeness heuristic is and how it works. Illustration by Cindy Chung, Verywell What Is the Representativeness Heuristic? When making decisions or judgments, we often use mental shortcuts or rules of thumb known as  heuristics. For every decision, we dont always have the time or resources to compare all the information before we make a choice, so we use heuristics to help us reach decisions quickly and efficiently. Sometimes these mental shortcuts can be helpful, but in other cases, they can lead to errors or  cognitive biases. The representativeness heuristic is one heuristic that we use when making judgments. In this particular example, we estimate the likelihood of an event by comparing it to an existing prototype that already exists in our minds. Our prototype is what we think is the most relevant or typical example of a particular event or object. Example of How It Works The representativeness heuristic was first described by psychologists Amos Tversky and Daniel Kahneman during the 1970s. Like other heuristics, making judgments based on representativeness is intended to work as a type of mental shortcut, allowing us to make decisions quickly. However, it can also lead to errors. When we make decisions based on representativeness, we may be likely to make more errors by overestimating the likelihood that something will occur. Just because an event or object is representative does not mean its occurrence is more probable. Consider the following description: Sarah loves to listen to New Age music and faithfully reads her horoscope each day. In her spare time, she enjoys aromatherapy and attending a local spirituality group. Based on the description above, is Sarah more likely to be a school teacher or a holistic healer? Many people would identify her as a holistic healer based on representativeness. She fits in with our existing ideas of how a holistic healer might behave. In reality, it is far more likely that Sarah is actually a school teacher based purely on probability. School teachers are far more common than holistic healers. Classic Research   In their classic experiment, Tversky and Kahneman presented the following description to a group of participants: Tom W. is of high intelligence, although lacking in true creativity. He has a need for order and clarity, and for neat and tidy systems in which every detail finds its appropriate place. His writing is rather dull and mechanical, occasionally enlivened by somewhat corny puns and by flashes of imagination of the sci-fi type. He has a strong drive for competence. He seems to feel little sympathy for other people and does not enjoy interacting with others. Self-centered, he nonetheless has a deep moral sense. The participants were then divided into three separate groups and each group was given a different task. The first group was asked how similar Tom was to one of nine different college majors. The majority of participants in this group believed Tom was most similar to an engineering major and least similar to a social science major.Participants in the second group were asked to rate the probability that Tom was one of the nine majors. The probabilities given by the participants in the second group were very similar to the responses given by those in the first group.In the third group, participants were asked a question unrelated to Toms description. They were asked to estimate what percentage of first-year graduate students were in each of the nine majors. What the researchers found was that people were highly likely to believe that Tom was an engineering major, despite the fact that there was a relatively small number of engineering students at the school where the study was conducted. People were likely to believe that Tom was an engineering major based on representativeness, ignoring other pertinent information such as the small number of engineering students. Toms description matched with what they believed was a good representation of an engineering major, so the representativeness heuristic led them to make a judgment about what major he was likely pursuing. In the Real-World The representativeness heuristic can play a major role in many real-life decisions and judgments. Consider, for example, how members of a jury might determine a defendants guilt or innocence. If the accused looks like what the jurors think a criminal should look like, with a menacing presence, scruffy face, and angry eyes, they might be more likely to perceive that individual as guilty of the crime of which he or she is accused. Assessments of guilt can also depend upon how well the crime represents a certain crime category. For example, a person accused of abducting a child for ransom may be more likely to be viewed as guilty as someone accused of kidnapping an adult for no ransom. While both crimes represent kidnapping, the first is a more representative example because it fits better with what most people think of when they hear the word kidnapping. This heuristic can also play a role in the assessments we make about other people. We tend to develop ideas about how people in certain roles should behave. A farmer, for example, might be seen as hard-working, outdoorsy, and tough. A librarian, on the other hand, might be viewed as being quiet, organized, and reserved. How well an individual fits into these representations of each profession affects our view of how probable it is they hold one of these positions. In their classic 1974 book Judgment Under Uncertainty: Heuristics and Biases, Tversky and Kahneman describe one example of how the representativeness heuristic can influence our perceptions of other people. They describe an individual who is seen as shy, withdrawn, helpful, but not necessarily concerned with the world of reality. This person is also described as tidy, meek, and detailed with a passion for order and structure. If you had to make a judgment about which profession this individual likely holds, which one would you select: farmer, salesman, airline pilot, librarian, or physician? In the representativeness heuristic, the probability that Steve is a librarian, for example, is assessed by the degree to which his is representative of, or similar to, the stereotype of a librarian, Tversky and Kahneman explain. A Word From Verywell The representativeness heuristic is just one type of mental shortcut that allows us to make decisions quickly in the face of uncertainty. While this can lead to quick thinking, it can also lead us to ignore factors that also play a role in shaping events. The next time you are trying to make a decision, consider the way in which the representative heuristic might play a role in your thinking.

Ideological Differences On Renewable Energy - 1084 Words

Ideological Differences on Renewable Energy Ever wonder what the world would be if there was no more energy, no more electricity in our household and no more gas for our car? Energy is a necessary resource that is used every day in American households and vehicles. Unfortunately, majority of the energy that is currently used comes from fossil fuels. Fossil fuels are un-renewable energy, which means that one day that it would eventually disappear. Unlike fossil fuels, there is an alternative way to get energy, from renewable sources. I will be presenting the Democrat’s and the Republican’s views on renewable energy use and also be comparing the similarities and differences. I will also explain my own perspective on renewable energy use†¦show more content†¦By giving support to renewable energy projects, it help increase the number of renewable energy jobs and helps decrease the use of fossil fuels. They have made improvements on its current renewable energy use but, according to Usnews, the Democrats have a plan for 2035. â€Å"As part of an ‘all-of-the-above’ energy policy, generating 80 percent of the nation s electricity from clean energy sources by 2035† (Usnews). If the majority of the nation’s electricity comes from renewable energy, there would be less of a need to use the depleting fossil fuel supply. The Democrats have increased the use of renewable energy by legislation and will continue making renewable energy the new standard instead of fossil fuel. Even though Democrats believe renewable energy is the way of the future, there are others who do not necessarily think so. Unlike the Democratic Party view on renewable energy, the Republican Party believe that fossil fuels should be the main focus instead of renewable energy. According to the GOP, Republican Party, website, the Republicans actually encourages renewable energy, but they think â€Å"the taxpayers should not serve as venture capitalists for risky endeavors† (GOP) The Republicans think it is too big of a risk to invest into the renewable energy. The reasons why renewable energy is riskier is evident on the Whitehouse website. â€Å"Today, solar power is significantly more expensive than electricity from fossil fuels in most regions of the

Sexual Harassment in the Workplace Andrew Frano BA 210 Joe Winter May 10, 2004 Andrew Frano Joe Winter BA 210 May 5, 2004 Sexual Harassment in the Workplace Sexual harassment occurs quite frequently in various workplaces and can consist of many different situations. In todays world though, females are not the only ones who have to deal with this problem, believe it or not, males do too. There are many ways of dealing with these situations, but getting the harassment to stop is not as easy. Dealing with sexual harassment today does not just include unwelcome sexual advances, but slurs, lewd remarks, and much more. Many laws have been set up to interact with these problems. Unfortunately, most of these laws are not followed†¦show more content†¦Another criticism that can happen to women is the assumption that somehow they Ask for it by their manner of dress or behavior. You have to realize that the victim does not create the problem; the harasser creates the problem. In conclusion, if attempts to resolve the situation are not successful or the harassment is continual, dont be afraid to seek help. Keep in mind that filing a formal complaint with the city, state or with a federal agency may be the only way to get a positive result. Victims of sexual harassment are not the only ones that need to be aware of various situations, but employers need to understand the concept too. The cost of sexual harassment in the workplace is expensive. A harassing atmosphere at work will cause low employee morale and high turnover. This usually leads to low production or quality of work. Many times a victim of harassment will simply quit and leave a job rather than have a confrontation about it. This cost money for the employer to hire and train new workers. If a complaint if filed with an enforcement agency, there will be additional costs for the staff time and legal counsel to the complaint. This will lead to the employer having to pay for damages for lost pay or emotional distress. If a charge of harassment becomes public knowledge, a business could suffer loss of customers and public good will. Many things need to be known by employers to prevent harassment.

Executive Privilege Free Essays

string(109) " executive privilege can have its usefulness, but it should only be invoked in certain, specific situations\." Executive Privilege| | | | Virginia Commonwealth University November 14, 2012| | In the past, the power of executive privilege has been used by Presidents to conceal information that has to do with foreign affairs and negotiations, military, national security issues as well as deliberations and policy making that is done between the President and his top aides. This power is only used when Congress asks the President or one of his top aides to produce all of the information pertaining to an event or situation. If the President then feels that parts of this information needs to be kept secret to protect the best interest of the public, or the other issues listed previously, then he will use executive privilege in order to not give that information to Congress. We will write a custom essay sample on Executive Privilege or any similar topic only for you Order Now A huge part of executive privilege is to protect the deliberations and advice given by the President’s aides. When the President’s advisors give him advice, they need to be able to give him the best advice possible and if there is a chance that everything they said could be made public. For instance if the President and advisors are discussing what needs to be done in relation to a foreign power and one suggests to nuke them, one suggests a covert attack and one suggests a peaceful resolution. If the final decision is a peaceful resolution, and Congress asks for all of the information on the subject, then the President should use executive privilege to keep those other possible outcomes from going public, both to keep the public from getting out of control or uneasy and to keep the other country from finding out the other options and retaliating. This power ensures that the President’s advisors can be completely honest and say what needs to be said without being worried about their words being taken the wrong way or too harsh or hurt their image. A big argument for those against executive privilege is that there is nothing in the constitution about it even though there is something about Congress keeping secrets. Article I states that â€Å"Each House shall keep a journal of its proceedings, and from time to time publish the same, excepting such parts as may in their judgment require secrecy† (US Constitution, Article 1 Section 5). Their argument is that the Constitution states that each House can withhold information that they think should be kept secret and there is nothing about secrecy when it comes to the President’s powers, however just because the words are not explicitly in the constitution does not mean that this power was not intended for the President. Even our founding fathers appreciated the importance of executive privilege and that is highlighted by this passage taken from The Works of Alexander Hamilton. In 1794, the Senate asked President George Washington, â€Å"‘to lay before the Senate the correspondences which have been had between the Minister of the United States at the Republic of France, and said Republic, and between said Minister and the office of Secretary of State. † Washington consulted his cabinet members, Henry Knox, Alexander Hamilton, and Edmund Randolph. Alexander Hamilton later wrote: General Knox is of the opinion that no part of the correspondences should be sent to the Senate; Colonel Hamilton is of the opinion that the correct mode of proceeding is to do what General Knox advises; but the principle is safe, by excepting such parts as the President may choose to withhold; Mr. Randolph is of the opinion that all correspondence proper, from its nature, to be communicated to the Senate, should be sent; but that what the President thinks is improper, should not be sent. Washington later told the Senate â€Å"After an examination of [the correspondence], I directed copies and translations to be made; except in those particulars, which, in my judgment, for public considerations, ought not to be communicated. † (Hamilton 1851) Three of these men signed the constitution and contributed a great deal towards it and they clearly believe that it is the President’s right to withhold information that he deems unfit to be made public. When it comes to foreign affairs it is very important that the President has the ability to use executive privilege. For instance, if the United States was making a treaty with another country, both countries may have to give things up in order to come to an agreement, and everything considered by both sides as well as everything agreed upon should not be made public for everyone, including other countries to see. This is best stated in 1796 by George Washington after the House of Representatives requested that he give them information concerning his instructions to the United States Minister to Britain regarding the treaty negotiations between the United States and Britain. Washington replied by saying: The nature of foreign negotiations requires caution, and their success must often depend on secrecy; and even when brought to a conclusion a full disclosure of all the measures, demands, or eventual concessions which may have been proposed or contemplated would be extremely impolitic; for this might have a pernicious influence on future negotiations, or produce immediate inconveniences, perhaps danger and mischief, in relation to other powers. The necessity of such caution and secrecy was one cogent reason for vesting the power of making treaties in the President†¦the boundaries fixed by the Constitution between the different departments should be preserved, a just regard to the Constitution and to the duty of my office.. , forbids a compliance with your request. † (Richardson 1897) As Washington states, we cannot simply make every detail public because other countries may retaliate and they will also be less likely to deal with the United States in the future. However, by invoking executive privilege the President can protect that information from causing such havoc. As he stated, it is not only the President’s right to use executive privilege, but it is his duty to use it in situations that require secrecy. Without a doubt executive privilege can have its usefulness, but it should only be invoked in certain, specific situations. You read "Executive Privilege" in category "Essay examples" In our recent history this has not been the case, some of our Presidents have tried to abuse the power of executive privilege, giving it a bad name and encouraging people to believe it should be done away with. When President Richard Nixon was in office, the Watergate scandal surfaced and Congress asked him to produce all of the information he and his aides had on the case. In an attempt to conceal what had been done as well as to protect everyone from punishment, President Nixon tried to use executive privilege. This case was brought to the United States Supreme Court because the executive privilege was being used to protect one of Nixon’s advisors from criminal prosecution, thus obstructing justice. This was by far an abuse of executive privilege and leads many to want it gotten rid of, however just because a power can be abused does not mean that its use should stop; it just means that restrictions need to be put in to place. This is highlighted by the ruling of the Supreme Court. The Court acknowledged the need for the President to used executive privilege, but determined that in cases of inquiry into possible criminal actions, the Executive has to release relating information. If we want to curb the abuse of executive privilege, we need to put guidelines into place, because without them, the meaning of executive privilege is at the discretion of the President until checked by other branches. President Nixon was neither the first nor last President to abuse this power (United States v Nixon 1974). President Bill Clinton also tried to invoke executive privilege in a very wrong way as well. Clinton tried to use executive privilege to prevent his advisors from testifying on whether he had sexual relations with Monica Lewinski or not. However, this claim of executive privilege was shot down, rightfully so (Baker 2012). These instances of abuse may lead some to think it is just a better option to not have executive privilege, but as long as barriers and restrictions can be put into place on it to prevent this from happening in the future, this power needs to stay around. This comes with some exceptions; this power should only be used when the President truly believes that if this information were to get out it would either be damaging to the public or in the best interest of the public to not find out. This power should also be used in situations where the President needs to protect national security intelligence and other matters as well as being used to protect military secrets, operations and intelligence. Lastly, this power should be used in situations where the United States is dealing with a foreign power, whether it is a treaty, a negotiation, a meeting or anything else containing sensitive material that either the United States or the foreign power needs to be kept secret. This brings up another argument against executive privilege. Some feel that this power should be done away with because Congress does not have the power of checks and balances over executive privilege; however that is not the case. If the President is refusing to give Congress the information that they are asking for, they can decide to stop funding things that the President is trying to do. They can also hold people in contempt of Congress, which was done as recently as this year in the Fast and Furious case where Congress demanded that Attorney General Eric Holder give them all the information on this case. President Obama stepped in and claimed executive privilege, however in a response to this, Congress moved, then voted to hold Holder in contempt of Congress unless he hands over the information (Silverleib 2012). Another thing Congress can do if the President continues to refuse to cooperate is to impeach him. This would obviously be only done in serious situations, but would work either to get their message across or to show future Presidents that they cannot just invoke executive privilege without consequence. On top of this, the courts can rule on cases where the President tries to use executive privilege like they did in the case with President Nixon. Articles II of the Constitution states that the President â€Å"shall from time to time give to the Congress information of the state of the union, and recommend to their consideration such measures as he shall judge necessary and expedient† (US Constitution Article II Section 3) As the Constitution says, the President does need to inform Congress on the State of the Union from time to time, however it does not say anywhere that the President is required to divulge all the information having to do with certain incidents. Between Article I and Article II, others take this to mean that Congress has an unlimited power of inquiry, but in reality that is not the case. This fact has been ruled on multiple times by different courts, where usually they determine that either the President does not have to give up the information, or that the President has to give up certain aspects of that information based on other laws. It is also Congress’s right and duty to challenge the President when he uses executive privilege, in order to make sure that the power is not being abused, which is the exact reason for having separate branches and a balance of power. If it wasn’t for executive privilege, other countries might be less inclined to deal with the United States because they fear that every detail could go public. Along the same lines the president’s advisors can’t give their best advice if they have to worry that anything they say could be made public. Military secrets and intelligence also needs to be protected to better ensure our troops safety as well as protect our country and citizens from retaliation after an exposed military operation. There is also information that needs to remain secret because it is in the best interest of the public to not find out. Lastly and most importantly, if it wasn’t for executive privilege, national security and military intelligence matters could be made public, exposing our informants and jeopardizing our national security. In order to keep this power alive and protect sensitive information, the United States needs to add guidelines or an amendment that properly codifies executive privilege to prevent its abuse. Once this is done, in theory, there would not be any more issues of whether power can or cannot be used. Everything would be stated to say that the President can only use executive privilege in the situations previously stated and any other instance where executive privilege is claimed would be thrown out. Executive privilege helps to protect our citizens, our national security and our good standing and ability to negotiate with other countries. If we were not able to guarantee that level of secrecy it would be nearly impossible to conduct policy making, decision making, foreign negotiations, treaties, as well as threaten the United States and their citizens’ safety.

The Food and Beverage Industry Role in the Tourism

Introduction Hospitality management is a complex, wide and extremely diverse field. This field is exceptionally challenging in terms of anticipating the needs of clients and guests. Besides, it is not a profession for everyone. It needs creative people, able to identify the needs of clients, ready to work with the public, and people who can think quickly when it comes to solving problems (Barrows and Powers 99).Advertising We will write a custom essay sample on The Food and Beverage Industry Role in the Tourism specifically for you for only $16.05 $11/page Learn More According to The Food and Beverage Industry in Taiwan, this industry has grown tremendously over the last one decade. This paper looks at the food and beverage industry, which is an important field in hospitality management and one that lies at the center of the tourism industry. The essay begins by looking at the food and beverage industry in general, and then proceeds to look at the main s ectors of the industry. The essay also reviews some of the reasons behind the growth of the industry. The remaining parts include elements of the industry, market assessment, and consumer needs, kitchen and dinning room designs, menu planning, cost control, food processing, and market technologies. Food and Beverage Industry Over the last few decades, the food and beverage industry has tremendously flourished in the business market from serving few individuals to international corporations. There is an increasing number of people having their meals in hotels and buying packed food when travelling or going for picnics. This growth in the food and beverage industry has also resulted into the growth of several companies such as Coca-Cola and Starbucks. Main sectors of Food and Beverage Industry The food and beverages industry falls into two major sectors, viz. commercial and subsidized/welfare. As a commercial entity, the industry further falls into two sub sectors, viz. restricted mar ket and general market. Restricted market includes transport catering, clubs, workplace catering, and institutional food and beverage preparation. General market comprises of hotels, restaurants, snack bars, pubs, vending machines, and fast foods. Subsidized food and beverage industry also falls into two sectors, viz. institutional catering and employee catering. Institutional catering applies to the operations in schools, universities, colleges, hospitals, prisons, and any other institution where they offer similar services (Davis, et al. 83). Reasons behind blossoming of the Industry People choose to go out, for instance, to celebrate a special function like graduation or when one gets job promotion. People also eat out when they are meeting friends. Hotel setting is a good place to meet new people or people that one would not want to meet at home. People could also eat away from home to commemorate an event. It could be a birthday or an event that positively influenced an individ ual or a group.Advertising Looking for essay on business economics? Let's see if we can help you!

Food and beverage operation centers are equally good locations to have meetings. Moreover, people eat out while travelling, especially on long journeys. In addition, people eat out when they are at work, attending a workshop, or in school. All these reasons are driven by the fundamental fact that the food and beverages industry is specifically designed to satisfy the demands of the consumers. Elements of Food and Beverage Industry There are eight elements of food and beverage industry. The first element is monitoring the needs of consumers for consumer satisfaction is very necessary for the existence of the industry. The second component is production and service aspects, which are perhaps the most important factors in the industry. They are two-wa y, viz. the owner gets the profit and the consumer gets quality service. The third element is monitoring of costs and revenues. The other elements include consumer and market, formulation of policy, interpretation of demand, provisioning, and convergence of facilities. Market assessment and Consumer Needs Market assessment and consumer needs are two great factors to consider when setting up a food and beverage establishment. After analyzing the food and beverage industry through market research, one can prosperously decide to establish the business. Therefore, it is important to employ market research skills (market information, questionnaires, and sales-analysis among others) to map out the industry framework (Haverkamp 81). Apart from market research, there is also market-segmentation. Knowing one’s clients and especially the food they eat is equally essential. People from different places may prefer different foods and drinks. Idea generation is also important in market as sessment. Even as one thinks about venturing into the food and beverage industry, factors such as prices, product quantity, concept development, and market competition should provide good sessions for brainstorming (Enzing 23). Service Operation System There are three important services in the food and beverage industry. The first service is acquiring raw materials, in what is called the â€Å"input service† in the food and beverage industry. Once the unprocessed materials are available, the second service is processing them into food. The last service is the â€Å"output†, which entails serving the food to the customers. Format of food and beverage production Usually the format of food and beverage production begins with the store. Once the raw materials are gathered, they should be kept in a clean and neat store. Equipments such as refrigerators should be in good condition. From the store, the next step is preparation, which could be done by either cooking the food o r simply cleaning up in the case of fruits. It is also important to pay keen attention to methods and recipes during food preparation. Besides, food flavor must be kept consistent in all meals, and that aspect requires close monitoring.Advertising We will write a custom essay sample on The Food and Beverage Industry Role in the Tourism specifically for you for only $16.05 $11/page Learn More Before serving the food, the dining room should be neatly prepared. Clients may put up with other weaknesses, but cannot compromise tidiness. When customers are through with eating, the table should be immediately cleared. The last step is washing of dishes, cleaning of debris, and disposing stuff that cannot be re-used. This last step is imperative in food and beverage industry. Designing Dinning Room/Sitting Area Be it in a hotel, pub, club, restaurant, or any other outlet in the food and beverage industry, the sitting area/dining room should appear in a manner th at is easily accessible to customers. Inasmuch as the owner may want to accommodate many people as he or she can, the arrangement should be in a way that allows free flow of customers in and out without pushing and shoving. In addition, the arrangement should be in a way that clients are can have some sort of privacy. For example, people on one table should be in a position to discuss their private issues without having to worry about other people on the next table. Therefore, it should be in a way that the serving staff can easily access the clients in the shortest time possible. The host may also consider fixing some form of music speakers around the room. Soft music, for instance, adds to the environment of hotels and restaurants. Clubs and pubs are exceptional in terms of volume and music they play (Lentz 85). Designing Kitchen Although customers do not go to the kitchen or even access its location, it is equally important to design it in a way that adds to the overall productio n of the industry. The kitchen is partitioned into several areas. The store, for example, should have enough shelves and refrigerating facilities. The washing area, which also includes sinks, should be spacious and kept clean all the times. There should be a set area for processing raw materials. Peeling and chopping, for instance, should be done in this section. Cooking should occur in a clean separate area with proper ventilation. There should also be a post-preparation area for keeping the prepared food before serving the customers. The other important part is the storage area utensils and pans.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Menu Planning The menu is extremely important when it comes to the food and beverage industry. It underscores what the customers look at when they visit a hotel, and interestingly, it is behind the fall of many businesses. However, in planning the menu, several critical factors stand out conspicuously. They include food preferences, customer food habits, prestige of the customers, economic factors, nutritional factors, tastes of the food, cultural background of the expected customers, and emotional aspects. It is also important to consider the availability and ease-of–use of products to be processed into food and beverages. Lastly, the management can upgrade the existing menu by paying much attention to the customers’ demands (Ojugo 35). Cost Control Businesses exist primarily to make a profit and thus the food and beverage industry is not exceptional. Possibly, the first path to this goal is cost control. This aspect requires evaluation of spending and maximization of profits. As of today, there are three approaches to cost control. The first approach calls for the management to supervise the personnel directly to ensure maximum production. The second approach is by rationalizing the costs based on performance (Guler 161-170). The latter is mostly popular in the food and beverage industry. The management should establish goals and then weigh them against service operations. It also means coming up with ways to measure performance. In addition, given that it hinges on performance, the management compares the actual results with the expected goals. Lastly, cost control could be managed by corrective action. When necessary, the management may also consider reshuffling the staff or getting professional personnel. The third approach is menu pricing. Paying attention, for instance, to how the customers perceive menu pricing is extremely important. The menu pricing also holds the demand of guests (Ojugo 180). Food processing Food processing refers to t he method of transforming unprocessed products into ready products for consumption. In food and beverage industry, food processing occurs in fours ways. The first method is a one-off production, which is used when clients request for special food and drinks with their own specifications. A good example is a wedding cake, which is made for specific customers only. The second method is batch production, which is used when the demand of the product is not consistent. The management prepares food based on an estimated number. The third method is mass production, which is applicable on products that are on demand. The last method is just in time. In this method, customers choose what is to be included in their food before preparation (Davis, et al. 74). Food and Beverage technologies Computer technology is an important element of in the food and beverage industry. Computers speed up paper work, especially in the field of data recording. They also find a wide application in the area of im proving customer service. Moreover, computers are useful in increasing sales revenue by enhancing personnel productivity. In addition, computer networks have eased bookings analysis and daily work schedule (Seric and Saura 7-38). Media and marketing technologies are also important elements in increasing production in food and beverage industries. Both of these technologies help in keeping consumers close to the products, especially during changes or new products in the market (Xia 93). Conclusion The food and beverage industry is an extremely complex, wide, and diverse market. When people eat out while travelling, go to clubs, have their meals and drinks in hotels and restaurants, spend a night in a hotel, or go watching movies/cinemas that are routinely marked with snacks, they are simply patronizing the food and beverage industry. This field can be interesting, but can also be exceptionally challenging. It requires people who are creative, able to identify consumer needs, willing to work with the public, and can think quickly when it comes to solving problems. Over the last decade, this industry has tremendously blossomed and has improved the tourism industry. Works Cited Barrows, Clayton, and Tom Powers.

Criminal Insanity essays

Criminal Insanity essays "Some traits or dispositions are inherited, but the continuity of behavior, including antisocial activity, is maintained by social contexts and other aspects of the Criminal insanity is a topic which sparks much heated debate. What causes insanity? Is insanity a physical or psychological problem? Is insanity actually a disease, or just a figment of a persons imagination? Groliers Encyclopedia describes insanity as "a mental defect or disorder sufficient to prevent a person from knowing the difference between right and wrong conduct or from understanding the nature of his or her actions." This definition is one which would seem to be a good representation of what insanity truly is. Insanity applies to criminals in an interesting way. If a criminal does not know the difference between right and wrong then can they be held accountable for the crimes they commit? If they don't understand that what they are doing is a crime then should they be punished as if they were criminals or treated as patients with a disease? This problem is one that has plagued courts, lawyers, juries and defendants for a long time and does not appear to be any closer to a solution. A common belief as to why people first become criminally insane is because of the way they were treated as children. Many examples to support this theory can be found throughout history. One example is the infamous Charles Manson. Charles Mansons' home life was anything but normal; he was, in fact, the son of a "teenage, bisexual, alcoholic prostitute, and was once traded for a pitcher of beer" ("Charles..."). Another example is Henry Lee Lucas, a famous serial killer, who "as a child, lost an eye after a severe beating from his mother" ("Serial..."). Finally, Pedro Alonso Lopez, believed to be the key player in over 300 murders was "kicked out of his house when only 8 years old" ("Serial..."). These cases, as well as many oth...

Homo Erectus Colonization in Europe

Homo Erectus Colonization in Europe Geoarchaeologists working on the coast of the North Sea of Britain at Pakefield in Suffolk, England have discovered artifacts suggesting that our human ancestor Homo erectus arrived in northern Europe much earlier than previously thought. Homo Erectus in England According to an article published in Nature on December 15, 2005, an international team led by Simon Parfitt of the Ancient Human Occupation of Britain  (AHOB) project has discovered 32 pieces of black flint debitage, including a core and retouched flake, in alluvial sediments dated to about 700,000 years ago. These artifacts represent the debris created by flintknapping, the manufacture of a stone tool, possibly for butchering purposes. The flint chips were recovered from four separate places within the channel fill deposits of a stream bed which in-filled during the inter-glacial period of the Early Pleistocene. This means that the artifacts were what archaeologists call out of primary context. In other words, fill in stream channels comes from soils moved downstream from other places. The occupation site- the site where the flintknapping took place- may be just a little upstream, or quite a ways upstream, or may, in fact, have been completely destroyed by movements of the stream bed. Nevertheless, the location of the artifacts in this old channel bed does mean that the artifacts must be at least as old as the channel fill; or, according to researchers, at least 700,000 years ago. The Oldest Homo Erectus The oldest known Homo erectus site outside of Africa is Dmanisi, in the Republic of Georgia, dated to approximately 1.6 million years ago. Gran Dolina in the Atapuerca valley of Spain includes evidence of Homo erectus at 780,000 years ago. But the earliest known Homo erectus site in England prior to the discoveries at Pakefield is Boxgrove, only 500,000 years old. The Artifacts The artifact assemblage, or rather assemblages since they were in four separate areas, include a core fragment with several hard-hammer percussion flakes removed from it and a retouched flake. A core fragment is the term used by archaeologists to mean the original hunk of stone from which flakes were removed. Hard hammer means the flintknappers used a rock to bang on the core to get flattish, sharp-edged chips called flakes. Flakes produced in this manner may be used as tools, and a retouched flake is a flake that shows evidence of this use. The rest of the artifacts are unretouched flakes. The tool assemblage is probably not Acheulean, which includes handaxes, but is characterized in the article as Mode 1. Mode 1 is a very old, simple technology of flakes, pebble tools, and choppers made with hard hammer percussion. Implications Since at the time England was connected to Eurasia by a land bridge, the Pakefield artifacts dont imply that Homo erectus needed boats to get to the North Sea coastline. Neither does it imply that Homo erectus originated in Europe; the oldest Homo erectus are found at Koobi Fora, in Kenya, where a long history of earlier hominin ancestors is also known. Interestingly, the artifacts from the Pakefield site also do not imply that Homo erectus adapted to a cooler, chillier climate; during the time period in which the artifacts were deposited, the climate in Suffolk was balmier, closer to the Mediterranean climate traditionally considered the climate of choice for Homo erectus. Homo erectus or heidelbergensis? The Nature article merely says early man, referring to either Homo erectus or Homo heidelbergensis. Basically, H. heidelbergensis is still very enigmatic, but may be a transitional stage between H. erectus and modern humans or a separate species. There are no hominid remains recovered from Pakefield as of yet, so the people who lived at Pakefield may have been either one. Resources and Further Reading Parfitt, Simon L.

LensCrafters Case Study Essay Example | Topics and Well Written Essays - 1500 words

LensCrafters Case Study - Essay Example These factors, together with the chain’s value chain and potential challenges are the principal focus of this paper. LensCrafters’ operations strategy and sustainability based competitive advantage LensCrafters was the first optical vendor to promise its customers quality eyeglasses within a short duration of one hour. The chain is able to attain this challenging feat by introducing autonomous onsite optometrists, fully equipped optical laboratories, as well as, a broad range of glasses’ frames at every outlet. LensCrafters’ operations strategy is guided by its mission, which explicitly states that the chain focuses on being the world’s best optical outlet. This happens through creating a loyal customer base, by promoting formation of a dynamic team of leaders and associates, who craft high quality eyewear in just one hour, and deliver superior services that meet customer’s personal needs and preferences (Collier & Vans, 2011). It is clear th at LensCrafters is a distinctive optical chain in marketplace, since it offers full laboratory analysis onsite and is also able to provide the customers with quality eyeglasses or contacts within one hour or even less. This service is coupled with a ninety day guarantee, which allows customers to return their spectacles unconditionally or exchange them, if they do not meet specifications. Additionally, the optical retailer offers an extended protection scheme and optometrists to give customers’ a comprehensive eyes’ examination, while offering them the chance to pay later. This allows them to broaden the customer base, since everyone can afford services provided (Collier & Vans, 2011). In terms of sustainability, the company has a broad range of strategies that give it competitive advantage over rivals in the optometric industry. For instance, LensCrafters has focused extensively on its philanthropic efforts in the diverse societies in which its service outlets are loc ated. An excellent example is the optical retailer’s partnership with Lions Club’s branches to facilitate recycling of used spectacles, in order to help those individuals that do not have enough money to purchase new eyeglasses. This distinctive service is provided not only in the chain’s American domicile, but also in developing countries like South America’s Puerto Rico. This philanthropic act enables the optical dealer to provide its immense expertise to needy individuals. The strategy has brought the company a lot of goodwill among customers, since they know that associating with LensCrafters allows them to reach out to the underprivileged in society. Humanitarian efforts, therefore, gives LensCrafters competitive advantage over other global optical companies. For specificity, the company has programs like â€Å"Give the sight gift†, in which the company offers vouchers to needy customers, for them to acquire free eyeglasses. There is also the â€Å"See more† program, whereby official company vans travel to public schools locally and internationally giving free eye care to kids (Collier & Vans, 2011). Another important aspect is that, LensCrafters’ staff work for longer office hours. This allows them to cater for many customers, in an economic environment characterized by extremely busy work schedules and little free time. The firm also upholds environment protection efforts, an action evident from its eyewear recycling program. All these efforts clearly depict LensCrafters’

Describe Fingerprint photographic technique you would use to recover Assignment

Describe Fingerprint photographic technique you would use to recover such marks following U.K. guidance - Assignment Example In general we have three types of fingerprints mainly latent, plastic and patent prints. Latent prints are formed from oils and sweat from the skin surface. They are invisible to un-aided eye, therefore; they require additional treatments. Patent fingerprints are made from ink, grease, dirt and blood. They are visible to the naked eye. Finally, the plastic fingerprints are in three-dimension, and they are made after pressing the hands on fresh soap, wax or paints. The prints are visible to the naked eye (Houck and Siegel, 2010, p. 29). To improve the visibility of latent fingerprints various lighting techniques can be used to obtain the invisible surfaces. According to Chaikovsky, Argaman, Batman, Sin-David, Barzovski and Yaalon (2005, p. 574), digital multiple exposure technique is applied. The process is simple and productive. Digital photography and computerized image processing with application of layers methodology produce many images that are easily controlled by computer programmes. Production of many images that are combined into a single image enables improved visualization of the selected portions of the latent print without affecting the rest part of the image. According to SIRCHIE (2013, p. 1), Crime scene photos are important in the crime scene inquiry. The photographs complement the investigator data in the form of data. A camera can be used to capture every object of importance within the crime scene. Warren (2014, p. 1), conducted a research to determine usage digital photography for forensic purposes. It was found out that digital imaging devices with spectral filters are very effective in the identification of untreated latent fingerprints in that it is viable and non destructive. According to the National Law Enforcement (2011, p. 6), it is believed that every individual has different body parts hence comparison of the measurements can be used to distinguish between two individuals. The method was developed by

Edgar Allen Poe Essay example -- Biography Biographies Poe Author Essa

Edgar Allan Poe Edgar Allan Poe was born at 33 Hollis Street, Boston, Massachusetts, on January 19, 1809. Poe’s parents were struggling actors. His father deserted him, and his mother died of tuberculosis when he was three years old. Young Edgar was taken in by a wealthy tobacco exporter by the name of John Allan, from whom he took his middle name. Most of his early life was lived in Richmond, Virginia, with the exception of a five-year period when the Allan family lived in England. His life in England was described as rather uneventful. Poe, even in his early years, had a proficiency for writing poetry. When he moved back to Virginia, Poe grew attached to young girl in his neighborhood named Sarah Royster. They frequently visited, where they sang songs and drew pictures. They were secretly engaged at the time, although their intentions were not made known to the adults of either household (Allen 9). His mid-life began when Poe entered the University of Virginia in 1926. He withdrew less than a year later. Initially, his grades were brilliant, but soon thereafter they began to deteriorate. It is reported that Poe gambled heavily and owed large sums of money to various shopkeepers (Benet 34). He also began drinking quite heavily. Mr. Allan refused to pay Poe’s debts. He also broke off Poe’s engagement to Sarah Royster. Without any visible means to support himself, Poe left for Boston. In the spring of 1827, he arrived penniless and enlisted in the army under the name of Edgar A. Perry. In 1829, he was promoted to the rank of sergeant major. At his own request, was honorably discharged in April of 1829 (Gullete 5). Temporarily reconciled, Mr. Allan secured Poe an appointment to West Point. But still refused financial support. After six months, Poe purposely got himself discharged from West Point, by purposely neglecting his military duties and for disobedience of orders (Encarta [CD-ROM]). Poe then moved to New York, and with the help of some money raised by his West Point friends, he published his first poems in 1831. Poe next took up residence in Baltimore, with his widowed aunt, Maria Clemm, and her daughter, Virginia. He turned to fiction as a way to support himself. The Philadelphia Saturday Corrier published five of Poe’s stories. In 1883, one of his pieces won a fifty-dollar prize given by the Baltimore Sunday advisor (Regan 2,3). In 1... ...il in a story should contribute to the story. Words must not be wasted. Poe’s life was short. He died at the age of forty. He did not appear to waste a moment of his life. He moved from Boston, to Philadelphia, to New York, and to Richmond in the early 1800’s. He even spent five years in London, England. All of these experiences shape his odd life. All of his experiences in his lifetime, including the bad memories, reflected how he wrote his literature. The reader had to understand every aspect of his life to better understand his stories and poems. His writings have been teachings and inspirations for the authors today. Poe is one of the most famous authors in today’s world because of his odd tales, and his eerie life. Works Cited Abbey-Cormier.

All I could see was blue salt water crashing on the sand shore in front of me. I stood up and touched the water, it felt fairly warm so I could tell I was somewhere besides California (where I lived at the time). I look over the horizon to see only blue skies. This worries me. I am still in my pajamas that are yellow with green palm trees. I turn around and see a fairly sized island with mostly all palm trees packed together into groups. I start walking to the palm trees, my feelings to what has just happened were kind of jumbled and I was confused. I’m halfway to the closest palm tree when I hear the bushes on my left side rustling. It could be my imagination or it could be the ocean breeze. I didn’t know which. To my surprise, it was neither. I push aside the bush only to see a huge lizard lumber out. I shook that off and continued walking towards the palm trees again. I reach the edge and start walking in. The farther I went in the darker it would get because of the dense vegetation. I had nothing else to do, so I continued walking farther and farther in. I tried carving lines into every tree trunk I passed so I could possibly find my way back. Eventually I gave up on that (It was to much work). The sun was going down and now all I was thinking about was where I was going to sleep. I came up with the idea to make a cushion of some kind and then put it up in a stable tree branch. I took the most comfortable looking leaves, stacked them on top of each other and hoped for the best. I woke up in the morning dazed and I could feel the sun rays beaming across the side of my face and my shoulders. The sun is out, but it’s still freezing. I started looking around for food because my stomach was growling, and to my surprise there was a pile of mangos piled neatly at the foot of a tree trunk. At the moment, I wasn’t thinking about how they got there like that, I was thinking about how delicious they looked. I reach over, grab the best looking one I can find, and shove almost half of it in my mouth and I dropped the second half. There was a haggard looking man walking toward me with a knife pointed toward me. At first he was yelling at me saying things, like it took him 3 days to get the mangos. Then he was questioning me, asking, How did you get here? Where are you from? and what do you want? I told him that I didn’t know how I got here, I was from California, and all I wanted was to go home. He told me that if I was hungry he could provide me with some, but very little food. I thought it was better than nothing so I followed him. He stopped in front of a fairly sized hut made out of palm tree branches and bamboo sticks. It sure did look a lot better then the leaf ‘†bed† I made. He pushes aside the seaweed curtain and proceeded to lead me in. There is no kind of furniture, but I am not surprised. I sit down around the fire he had going. He walks back to the fire with a dead, skinned monkey on a stick. Doesn’t look very appetizing but it’s better than nothing. He holds over the fire and slowly turns it until it is done cooking. He rips off a leg and hands it to me. I reach for it reluctantly. Right away he bites down into the monkey. He must have been very hungry, but so am I. I bite down into the thigh and it tastes a lot better than I thought it would. I am alarmed by the sounds of a helicopter. I rush out to see that helicopter landing on the open beach. Once it had landed I ran toward the window and started banging on it. All I wanted to do was return home. After a while of speaking to the men from the helicopter they told me they actually weren’t looking for me but for the haggard man I was with. He had been on that Island for 4 years! Then they tell me that they will only have room for him. They say that they will have to come back for me later. But how much later? Great.

VSED in Alzheimers Patients - Free Essay Example

Sample details Pages: 2 Words: 702 Downloads: 9 Date added: 2019/04/12 Category Medicine Essay Level High school Tags: Alzheimer's Disease Essay Did you like this example? Healthcare today has centered its focus on individuals having increased autonomy, especially with medical judgments. Autonomy is a fundamental principle giving individuals the liberty to determine their own actions based on the plan individuals choose for themselves. What happens, however, when one loses their ability to think or speak for themselves because their disease state has progressed so far? What happens when an Alzheimers patient considers voluntary stopping eating and drinking, or VSED, or if their family is making the decision for them as a surrogate? It becomes a moral conflict to provide a way, like VSED, to increase quality of life by ending it prematurely, to end their suffering. Don’t waste time! Our writers will create an original "VSED in Alzheimers Patients" essay for you Create order These decisions are made daily and, like death, are inevitable. We make decisions for ourselves on a daily basis. Many healthcare professionals, especially those who work in long-term care facilities, face the ethical dilemma to feed or not to feed those who are suffering from Alzheimers and dementia. Many questions revolve around what would the loved one want? Will you continue to feed because it will enhance their quality of life? What if stopping feeding will increase their quality of life? Most people, including the patient, the patients family and interdisciplinary team, want to preserve the patients autonomy and control. Facilitating VSED honors the request of autonomy if that is what the patient has chosen. Another benefit of VSED include increasing the familys comfort knowing that it was not their decision to end their loved ones life in this way. Family members experience great amounts of stress when decisions need to be made at the end of life, especially when the decisions are placed in their hands. It also gives family time to cope and have anticipatory grieving. They often wonder if they are doing the right thing and if that is what their loved one would have wanted. Nonmaleficence and beneficence: to do good and to do no harm. Beneficence involves healthcare providers treating patients utilizing ways to provide them with the maximum benefit possible while doing no harm (whether intentionally or unintentionally), or nonmaleficence. In a situation like VSED in Alzheimers patients, healthcare professionals must keep their beliefs and values masked about the situation and continue to provide care, as well as follow the patients wishes. The other side of the argument are the cons of VSED. Some view VSED as a form of suicide due to the definition of suicide†the act of taking ones life voluntarily and intentionally (citation). Many consider VSED as an act of suicide by omission. Some consider VSED a form of physician-assisted suicide (citation). Stated by Jack Kevorkian, As a medical doctor, it is my duty to evaluate the situation with as much data as I can gather and as much expertise as I have and as much experience as I have to determine whether or not the wish of the patient is medically justified. Dehydration and starvation are thought of as forms of neglect, but neglect can also mean not listening to what the patient or their family wants (citation). In many cases, the Durable Power of Attorney can modify the patients decision to stop eating or drinking if they feel like the patient would experience an increase in suffering, pain, and anxiety nearing their death. Others feel as if VSED is neglecting the human body, and that it is not allowing the body to succumb to death upon its own. Is it ethically justifiable for a surrogate to make the decision to refuse food and drinks on a patients behalf? If an individual with Alzheimers loses their capacity, they must rely on their legal surrogate decision maker to either continue or discontinue life-sustaining treatment, like VSED, when the opportunity arises. The patients wishes must be communicated to everyone involved in the decision-making process and care provided to the patient. This decision, however, can affect negatively on the family and the final decision can be a very controversial topic to family members. Keeping the patient alive for sake of family can be looked upon as a pro and a con. If the family chooses not to follow the patients wishes of VSED, family members may continue to grieve or prolong their grieving process.

INTRODUCTION Corporate Governance / PUNB 413 students are required to prepare an individual assignment which is includes preparing summary of at least two articles that related to ISSUES IN CORPORATE GOVERNANCE focusing on Directors Remuneration and CEO Compensation. The article that I selected is mainly focus on Directors Remuneration, Corporate Performance, Board Characteristics and factors that influence in determining the Directors Remuneration and CEO compensation. This assignment plays a vital role in developing our understanding and providing a clear picture on Corporate Governance in real world’s perspective. ARTICLE 1: Board Compensation Structure and Firm Performance Ivan E. Brick, Oded Palmon, and John K.†¦show more content†¦The CEO might control the board and hence reduce the efficiencies of the directors, monitoring. Meanwhile, the study also highlighted the relationship between directors’ compensation and the number of meetings. The number of board meetings considered as the amount of monitoring and effort required of directors. The impact of director incentive compensation upon firm performance can be examined in three ways: by using changes in Q, ROA and future ROA. Q and ROA will increase if the percentage of director’s incentive compensation is approximately at an average level. The directors’ pay-performance sensitivity has a relation with firm performance. When directors have more information about future firm performance, they are likely to pay themselves with more equity and share options. In addition, studies also discovered secondary relation ship between CEO compensation and firm performance. CEO compensation will influence the ROA. So, it has been examined that directors’ pay performance sensitivity is related to firm performance and CEO pay-performance sensitivity is primarily related to ROA. CONCLUSION: This study is mainly focused on the factors and impact of directors’ incentive compensation structure upon firm performance. Studies have discovered that the incentive compensation structure linked with variables that represent the need for monitoring by the directors is one of the factors in determining the director’s incentive.

Horgas, RN, PhD,A Amanda F. Elliott, ARNP, PhD,w and Michael Marsiske, PhDz OBJECTIVES: To investigate the relationship between self-report and behavioral indicators of pain in cognitively impaired and intact older adults. DESIGN: Quasi-experimental, correlational study of older adults. SETTING: Data were collected from residents of nursing homes, assisted living, and retirement apartments in northcentral Florida. PARTICIPANTS: One hundred twenty-six adults, mean age 83; 64 cognitively intact, 62 cognitively impaired. MEASUREMENTS: Pain interviews (pain presence, intensity, locations, duration), pain behavior measure, Mini-Mental State Examination, analgesic medications, and demographic characteristics. Participants completed an activitybased protocol to induce pain. RESULTS: Eighty-six percent self-reported regular pain. Controlling for analgesics, cognitively impaired participants reported less pain than cognitively intact participants after movement but not at rest. Behavioral pain indicators did not differ between cognitively intact and impaired participants. Total number of pain behaviors was signi? antly related to self-reported pain intensity (b 5 0. 40, P 5. 000) in cognitively intact elderly people. CONCLUSION: Cognitively impaired elderly people selfreport less pain than cognitively intact elderly people, independent of analgesics, but only when assessed after movement. Behavioral pain indicators do not differ between the groups. The relationship between self-report and pain behaviors su pports the validity of behavioral assessments in this population. These ? ndings support the use of multidimensional pain assessment in persons with dementia. J Am Geriatr Soc 57:126–132, 2009.

Dementia complicates pain assessment, because it impairs memory, judgment, and verbal communication. Dementia is associated with central nervous system changes that alter pain tolerance4 but not pain thresholds (e. g. , minimum level at which a painful stimulus is recognized as pain). 5 No empirical evidence indicates that persons with dementia physiologically experience less pain; rather, they appear less able to recognize and verbally com municate the presence of pain. Findings that cognitively impaired older adults underreport pain relative to nonimpaired elderly people7 and are less likely to be treated for pain than their cognitively intact peers8,9 re? ect dif? culty assessing pain in this population. Self-report is considered the criterion standard of pain assessment. Despite recent studies supporting the reliability and validity of self-report in persons with dementia,7,10 healthcare providers and pain experts recognize that selfreport alone is insuf? cient for this population and that observational pain assessment strategies are needed. In 2002, the American Geriatrics Society established comprehensive guidelines for assessing behavioral indicators of pain. 1 More recently, the American Society for Pain Management Nursing Task Force on Pain Assessment in the Nonverbal Patient (including persons with dementia) recommended a comprehensive, hierarchical approach that integrates selfreport and observations of pain behaviors. 11 Recently, tools to measure pain in persons with dementia have proliferated. In 2006, a comprehensive stateof-the-science review of 14 observational pain measures was completed. The authors concluded that existing tools are still in the early stages of development and testing and that more psychometric work is needed before tools are recommended for broad adoption in clinical practice. 12 Others, including an interdisciplinary expert consensus P JAGS 57:126–132, 2009 r 2008, Copyright the Authors Journal compilation r 2008, The American Geriatrics Society 0002-8614/09/$15. 00 JAGS JANUARY 2009–VOL. 57, NO. 1 PAIN ASSESSMENT IN PERSONS WITH DEMENTIA 127 panel on pain assessment in older persons,13 have corroborated these conclusions. 4 In particular, these authors highlight the need for more evaluation of observational pain measures, including validation against the criterion standard of self-report in intact and impaired populations. Almost all research on measuring pain in persons with dementia has focused exclusively on persons with moderate to severe disease. There has been only one published study that compared pain behaviors and self-repor ted pain in persons with and without cognitive impairment, but it focused on postoperative patients undergoing rehabilitation and acute pain associated with physical therapy. You read "Analgesic and Facilitator Pain Assessment" in category "Essay examples" 5 Thus, the purpose of this study was to investigate the relationship between self-report and behavioral indicators of pain in cognitively intact and impaired older adults with persistent pain. Speci? cally, this study evaluated whether cognitive status (intact or impaired) differentially in? uenced verbal and nonverbal expression of pain. It was hypothesized that self-reported pain would be lower in cognitively impaired elderly people than in those who were cognitively intact but that pain behaviors, because they are more re? exive and less reliant on verbal communication, would be equivalent in both groups. The relationship between pain behaviors and self-reported pain was also evaluated in cognitively intact elderly people to validate whether behaviors measured are indicators of pain. The following research questions were asked. Does cognitive status in? uence self-reported pain? Does cognitive status in? uence observed pain behaviors? Are self-reported pain and observed pain behaviors related, and is the relationship different in cognitively intact and impaired elderly people? One hundred forty participants were enrolled and completed the baseline interview; 126 (90%) completed the protocol. Attrition analyses revealed no signi? ant differences between completers and noncompleters on demographic, residential status, health, or pain variables. The ? nal sample was predominantly female (81%), Caucasian (97%), and widowed (60%), with a mean age of 83 (range 5 65–98). Thirty-nine percent resided in nursing homes, 39% resided in assisted living, and 22% lived independently in retire ment apartments. Participants’ average Mini-Mental State Examination (MMSE) raw score was 24 (range 5 7–30, median 5 27, mode 5 29). Based on 10th percentile education-adjusted MMSE norms as the cutoff,16,17 64 (50. 8%) were cognitively intact, and 62 (49. %) were impaired. See Table 1 for a description of the total sample and of cognitively intact and impaired subsamples. Groups differed only in residential status (cognitively Table 1. Sample Characteristics, Overall (N 5 126) and According to Cognitive Status Total Sample Cognitive StatusA Intact Impaired (n 5 64) (n 5 62) PValue Characteristic METHODS The University of Florida institutional review board approved this study. Informed consent was obtained from cognitively intact participants and from impaired elderly people’s legally authorized representatives, with assent from persons with dementia. Design A quasi-experimental, correlational design was used to investigate pain in older adults with mild to moderate dementia, because dementia status cannot be experimentally manipulated. Cognitively intact elderly people functioned as a comparison group to examine behavioral indicators and self-reported pain in the two groups. If self-report and behaviors were related in cognitively intact persons, there would be some basis to infer that the same behaviors indicated pain in cognitively impaired elderly people. Participants One hundred ? ty-eight older adults were screened for enrollment from 17 assisted living facilities, nursing homes, and retirement communities in north central Florida. Inclusion criteria were aged 65 and older, English-speaking, able to stand up from a chair and walk in place, diagnosed osteoarthritis in the lower body, and adequate vision and hearing to complete the interview.

Those eligible were interviewed about their pain and completed an activity-based protocol designed to evoke pain behaviors in persons with persistent pain (described in more detail below). Activity Protocol Participants were asked to sit, stand, lie on a bed, walk in place, and transfer between activities. Based on previous work, the activity protocol had several strengths for use with this population. First, it simulates performance of basic activities of daily living, thereby enhancing ecological validity of the tasks. Second, it was tested in other studies, and activities were shown to induce pain in persons with osteoarthritis and chronic low back pain, thus providing a naturalistic pain induction method. Third, use of these realworld tasks avoids undue health or safety risks for elderly adults and eliminates potential bias associated with arti? cially induced (e. g. , laboratory-based) pain induction techniques. 8,19 The protocol was simpli? ed by using only 1-minute activity intervals (to reduce complexity of directions and physical demands for frail or cognitively impaired participants) and substituted walking in place for walking across the room and back (to accommodate physical space limitations in residential care facilities where data were collected). Activities were conduct ed in random order to minimize order effects, and the entire 10-minute protocol was videotaped. Measures Self-Reported Pain The principal investigator (ALH) or a trained research assistant interviewed each participant in a private session about their pain experience. Pain presence, intensity, locations, and duration were assessed. Pain Presence. Questions from the Structured Pain Interview (SPI)20 were used to assess presence of self-reported pain. During the pain screening interview, participants were asked ‘‘Do you have some pain every day or almost every day (daily pain)? ’’ Pain was also assessed immediately before the start of the activity protocol (‘‘Are you having any pain right now? ’’ (pre-activity)) and immediately after it (‘‘Did you experience any pain during these activities? ’’ (postactivity)). Response choices to all three questions were yes (1) or no (0). Pain Intensity If participants responded ‘‘yes’’ to experiencing pain (daily, pre-activity, or postactivity), they were asked to rate the intensity using a numerical rating scale (NRS). The NRS was presented as a horizontal line with 0 5 no pain and 10 5 worst pain as anchors and equally spaced dashes representing pain intensity rating of numbers 1 through 9. The scale was printed in large, bold font on an 8. 5†³ A 11†³ paper to facilitate use with older adults who may have vision dif? culties. The NRS is considered valid, reliable and easier Pain Duration Participants were asked to indicate how long (in months and years) they had experienced daily or almost daily pain. Responses were coded as less than 1 year, 1 to 5 years, 6 to 10 years, 11 to 15 years, or more than 15 years. Pain Locations The pain map from the McGill Pain Questionnaire22 was used to assess pain locations. Participants indicated areas on the body drawing in which they were currently experiencing pain. Total number of painful locations was summed. This widely used measure has been validated in several epidemiological studies and has high interrater reliability (average kappa 5 0. 2). 23 Observed Pain Behaviors Pain Behaviors A modi? ed version of the Pain Behavior Measure18 was used to measure behavioral indicators of pain. Based on standardized behavioral de? nitions, occurrence of the following speci? c pain behaviors was evaluated: rigidity, guarding, bracing, stopping the activity, rubbing, shifting, grimacing, sighing or nonverbal vocalization, and verbal complaint. Standardized de? nitions were adapted from previous work,18,19 modi? ed for use in this older, moreimpaired population, and pilot tested in a sample of nursing home residents with dementia. 4 This measure has adequate reliability and validity. 13 Pain Behavior Coding Independent raters, all registered nurses blind to participants’ cognitive status, scored the videotaped activity protocols. Coders completed extensive training in coding procedures until intrarater and interrater agreement (with the master coder (PI) and another rater) reached a kappa coef? cient of 0. 80 or greater, indicating good to very good reliability. 25 After coding reliability was attained, reliability checks were conducted on 10% of all videotapes to minimize rater drift. Noldus Observer software was used to analyze digitized videotapes and code pain behaviors (Noldus Information Technology, Wageningen, the Netherlands). The following summary variables were created and used in the analyses: total number of pain behaviors observed, number of times each behavior (rigidity, guarding, bracing, stopping, rubbing, shifting, grimacing, sighing or nonverbal vocalization, and verbal complaint) was observed, and total numbers of pain behaviors observed during each activity state (e. g. , number of behaviors while walking, reclining, sitting, standing, and transferring). Cognitive Status Cognitive status was assessed using the MMSE,26 an 11-item screening instrument widely used to assess general cognitive status in elderly adults. The following MMSE scores served as the cutoffs to classify participants as intact or impaired: less than 8th grade education, 20; 9 to 11 years, 24; high school graduate or equivalent, 25; some college, 27; and college degree or higher, 27. 16,17 JAGS JANUARY 2009–VOL. 57, NO. 1 PAIN ASSESSMENT IN PERSONS WITH DEMENTIA 129 Analgesic Medications Drug data for each participant were coded according to the American Hospital Formulary Service system. All pain medications were identi? ed and converted to acetaminophen equivalents. 8,27 This standardized drugs and dosages to a common metric and facilitated comparison of analgesic dosing. To ensure that only analgesics actually taken would be controlled for, equianalgesic dosages were considered in these analyses only if they were taken within the standard therapeutic dosing window for each drug (e. g. , acetaminophen, every 4–6 hours) before the activity protocol. Data Analysis SPSS, version 15. 0 (SPSS Corp. , Chicago, IL) was used for data analysis. Descriptive statistics, Pearson chi-square (w2) tests, and t-tests were used to describe sample characteristics and examine group differences. Analysis of covariance (ANCOVA) was used to test relationships between cognitive status, pain intensity, and pain behaviors. Logistic regression was used to predict pain presence. Multiple regression was used to predict pain intensity and number of pain behaviors, with a centered cognitive status–by–pain intensity interaction term to identify group differences; standardized regression coef? cients (b) are reported in the results. RESULTS Self-Reported Pain The majority of participants (86. 5%) reported experiencing pain every day or almost every day. More than 65% reported experiencing pain for more than 1 year ( $ 40% indicated duration of 45 years). On average, participants reported pain in four body locations (range 5 1–25); usual pain intensity was 4. 3 (moderate) on a scale from 0 to 10. Immediately before the activity protocol, 45 (35. 7%) participants reported experiencing pain. Mean pain intensity was rated as 1. 7 (range 5 0–9). After the protocol, 79 (62. 7%) reported experiencing pain during the activities; mean pain intensity was 3. (range 5 0–9). Relationship Between Cognitive Status and Self-Reported Pain Chi-square analyses were conducted to examine the relationship between cognitive status (impaired vs intact) and presence of self-rated daily pain and pain duration at baseline. The baseline pain interview was not always conducted on the same day as the activity protocol, a nd analgesic use before the interview was not assessed. Thus, initial analyses are descriptive only and do not control for analgesic use. At baseline, 77. 4% of impaired and 95. 3% of intact participants reported experiencing pain every day (w2(1) 5 8. 6, P 5. 003). Cognitively impaired elderly people also recalled shorter pain duration (w2(3) 5 16. 0, P 5. 001) than intact participants, but no signi? cant differences were reported in the number of pain locations. Logistic regression, controlling for acetaminophen equivalents, indicated that cognitive status was not signi? cantly predictive of pre-activity pain presence. Regression analyses, with pre-activity pain intensity as the dependent variable and cognitive status and analgesics as predictors, revealed no signi? cant difference between the two groups (Figure 1).

JANUARY 2009–VOL. 57, NO. 1 JAGS At the end of the activity protocol, cognitive status was signi? cantly associated with the reported presence of pain, controlling for analgesics (b 5 1. 2, P 5. 002); cognitively impaired elderly people were less likely to report pain. Impaired participants also reported signi? cantly lessintense pain than intact participants after the activity protocol (3. 8 vs 2. 6; F (1) 5 A 5. 0, P 5. 03). Paired t-tests indicated that pain intensity increased signi? cantly from start to end of the protocol for both groups (Figure 1). Table 2.

A Relationship Between Cognitive Status and Observed Pain Behaviors On average, 21. pain behaviors per person (range 5 3–50, median 5 21, mode 5 16) were observed during the activity protocol. ANCOVA models, controlling for analgesics, revealed no signi? cant differences in mean number of pain behaviors observed between cognitively intact and impaired participants (covariate-adjusted means 5 21. 8 and 21. 3, respectively; F (1) 5 0. 08, P 5. 77). The number of oc currences of each of the eight behavioral indicators observed was summed. ANCOVA models, controlling for analgesics and using Bonferroni correction for multiple comparisons (P 5. 005), revealed no signi? ant differences between cognitively intact and impaired elderly people for any behavioral pain indicators investigated (Figure 1). Of the activity states observed during the protocol, transferring elicited the most frequent pain behaviors (mean 5 13. 4; range 5 2–43). No signi? cant differences were noted between cognitively intact and impaired participants in number of behaviors observed during any of the ? ve observed activity states. Relationship Between Self-Reported Pain and Observed Pain Behaviors Regression analyses were conducted to examine the relationship between elf-reported pain intensity and total number of pain behaviors observed, controlling for analgesics. Before the activity protocol, pain intensity was signi? cantly predictive of the pain behaviors sum score (b 5 0. 27, P 5. 002), but the relationship did not differ between cognitively intact and impaired participants. After the activity protocol, self-reported pain intensity was signi? cantly (and more strongly) related to number of pain behaviors observed (b 5 0. 40, P 5. 000), and the painby-cognitive status interaction was signi? cant (b 5 0. 22, P 5. 008). Thus, postactivity pain intensity and summed behavioral indicators were signi? antly related in intact but not impaired participants (Table 2). DISCUSSION It was found that cognitive impairment diminishes selfreported pain assessed at rest but only when analgesics are not controlled. At baseline, cognitively impaired elderly people were signi? cantly less likely than cognitively intact elderly people to report pain, consistent with reports in the literature,7 but when analgesics were controlled for, these differences disappeared. This ? nding highlights the need to control for analgesics taken when making group comparisons, whic h to the best of the authors’ knowledge, has not been previously done. The few studies reporting medication use include drugs prescribed or number of doses taken 0. 27 0. 01 0. 09 0. 08 2. 9 0. 40 A 0. 03 . 22 . 18 6. 70 .003 . 99 . 30 . 02 . 00 . 75 . 01 . 000 (regardless of medication class), whereas the current study identi? ed analgesics in the subject’s body during the pain assessment protocol. After the activity-based protocol was completed, selfreported pain intensity increased for both groups, but cognitively impaired elderly people reported less-intense pain than their intact peers. This ? ding supports the usefulness of the protocol to exacerbate pain in those with painful conditions and highlights the importance of mobility-based pain assessments. 12,14 This ? nding held even when the amount of analgesics taken by participants was controlled for in the statistical analysis. Behavioral indicators of pain observed during activities were equivalent across both groups. This ? nding contradicts previous work15 and may re? ect that medicatio n use was controlled for and that the focus of the current study was on persistent pain, as opposed to more-acute, postoperative pain. This research con? ms that reliance on selfreport alone is insuf? cient to assess pain in older adults with dementia, because the pain experience may be underestimated,11 and supports growing recognition that behavioral observation is a necessary and useful pain measure, particularly in subjects with cognitive impairment. Cognitively impaired elderly people took signi? cantly more pain medication than their intact peers. The difference was approximately 500 acetaminophen equivalents, approximately the dose of one extra-strength acetaminophen tablet. This ? nding, which contradicts previous work,8,9 warrants further investigation. Post hoc analyses indicated that this difference was not attributable to residential status, number of medical conditions, or demographic characteristics. Thus, it may re? ect recent changes in prescriptive practice as a result of heightened focus on pain in older adults with dementia. Another important ? nding is the signi? cant relationship between self-reported pain intensity and observed pain behaviors in cognitively intact persons. This ? nding provided support for the validity of behavioral pain JAGS JANUARY 2009–VOL. 57, NO. 1 PAIN ASSESSMENT IN PERSONS WITH DEMENTIA 31 indicators against the criterion standard of self-report, as least in cognitively intact elderly people, and is consistent with other researchers’ ? ndings. 28 Because there is no evidence that cognitively impaired elderly people experience less pain, it is reasonable to infer that pain behaviors are a valid indicator of pain in persons with dementia, although this assumption cannot be directly te sted unless biological tests are developed. 12,24 Pain is subjective, and pain behaviors can be dif? cult to interpret, be subject to bias, and lack speci? city. 14,29 It has been uggested that some behaviors may indicate anxiety or generalized distress, not pain, in those with advanced dementia. 29,30 Thus, pain behavior measurements should be used in conjunction with selfreport, not as a replacement, and in the context of a comprehensive pain assessment. 14,30 Study strengths are that cognitively intact and impaired elderly people participated, thereby facilitating comparison of assessment strategies in persons of differing cognitive abilities, that a careful analysis of analgesics used during the pain assessment was conducted, and that persistent pain was focused on. Most related prior research has included only persons with advanced dementia and postoperative pain. The sample was limited, however, by being primarily Caucasian and by being restricted to individuals with mild to moderate dementia. This was likely because of inclusion criteria requiring that participants be able to rise, stand, and walk. Individuals with severe dementia are typically more immobilized and unable to follow directions, factors that would impair ability to complete the activity-based protocol in this study. Thus, generalizations are limited, and further study is needed. This study contributes several important ? ndings to the discourse on pain assessment in persons with dementia. First, it was con? rmed that self-reported pain, although still attainable, may be less reliable in those with mild to moderate dementia than in cognitively intact elderly people, depending on when it is assessed. Second, assessment of pain during movement is supported. Cognitively intact and impaired elderly people both showed greater self-reported pain intensity after movement, indicating that static assessment may underestimate pain. Third, results support the validity of behavioral pain assessment against the criterion standard of self-report and provide evidence of an association between summed pain behaviors and self-reported pain intensity. More work is needed to establish scale properties of pain behaviors in relation to pain severity before this approach can be translated to clinical practice. Fourth, ? ndings highlight the importance of carefully evaluating analgesics taken when measuring pain, since results indicate that cognitively intact and impaired elderly people with persistent pain are often medicated differently. This ? nding may re? ect a change in prescriptive practice that warrants further investigation. (Dr. Horgas) and a John A.
