...One of the main challenges for freelance translators is to find suitable clients, and once they have found them, one of their main concerns is how to retain them. As a freelancer you may well find that working for translation agencies rather than for private clients offers both peace of mind and a more reliable flow of orders.  As a professional freelancer you are doubtlessly well aware of the many benefits of freelance work. Most of these will be associated with themes such as independence, freedom and - if you are lucky - considerable revenues. However, you may also have discovered a number of serious downsides to this kind of work. The one cited perhaps the most frequently is the ongoing pressure to attract clients. Although we know of no research to verify it, there is a law in the translation business which states that a freelance translator who has no work, is not a good translator. The opposite is also true: a good translator will never be at a loss for work. Even so, your order portfolio as a freelancer will also depend, at least in part, on your commercial skills in attracting clients, offering your services to potential clients, and building up networks. Once you have found enough clients for a sustainable business, moreover, you may find it difficult to balance your capacity with their needs.  In view of these considerations, it might be a good idea to offer your services to translation agencies as well. The rates they offer may not be as high as those of private...

...of an anaesthetic machine prior to use. On the morning of this particular learning experience I had already pre-informed the student of the event so we could start promptly. The student arrived on time as I did. We went straight to the operating theatre where we were going to be working for the day. On arriving in that theatre I discovered it had been used prior and was left in an untidy state so I had to tidy it up before we could proceed. Had I have thought before hand I could have checked the day before to ensure this was not the case. I started by showing the student the anaesthetic machine we were going to use, explained the different parts and how they function. The student looked a bit perplexed at the terminology I used so I tried more simple terminology and explanations and that seemed to help. After the brief explanation of how the anaesthetic machine worked I described The checks we were going to carry out. I showed the student the 2012 guide to checking the machine produced by the College of Anaesthetists which is the one we currently use. We started to check the machine going through the guide step by step as described. It took quiet a while to complete the check. Afterwards I asked the student if they followed what we had done, the student commented it was a bit too much to go through in one session. I think looking back that I should have broken down the process into perhaps two or more sessions allowing the student time to take in and question the...

Economist’s Jargon: Unite and Divide

...The economics profession’s jargon serves a variety of purposes. For example, their common terminology serves to make for more precise communication. It allows ideas to be communicated clearly and exactly. This exactness and clarity of terminology serves society by allowing economists to discuss economics with each other and with society with clarity so that other economists have a better understanding of what an economist is saying. A common terminology also serves to divide insiders from outsiders. For outsiders, for example economic students, who do not have a clue what these terms mean, economists’ terminology is exclusionary. It makes economists the gatekeepers of economic ideas. Economists’ terminology serves as a barrier to entry, restricting the supply of economists, and increasing the value of the services provided by existing economists. Which of these two reasons is the strongest? To answer that question let us consider two examples given by Amanda Bennett, the author of The Wall Street Journal article, “Economists + Meeting = A Zillion Causes and Effects” [The Wall Street Journal, January 10, 1995]. The two examples are the concepts of externality and utility, Why do economists use these terms? Based on her article, and on my classroom experience, I would judge that, of the two reasons, the self-serving reason is the stronger. Essentially, economists create their terminology primarily to make life difficult for students. Consider the first example: externality. Why...

Medical Terminology

...How Does Medical Terminology Work? ________________________________________ Most medical terms can be broken down into one or more word parts. For simplicity in explanation, we will say that there are four possible word parts, and any given medical term may contain one, some, or all of these parts. We will classify these word parts as (1) roots, (2) prefixes, (3) suffixes, and (4) linking or combining vowels. An example of a word with three of the above parts is the medical term "pericarditis", which means "inflammation of the outer layer of the heart". Pericarditis can be divided into three parts: peri - card - itis. Once divided into its essential parts, pericarditis can be translated: the prefix "peri" translates to "surrounding", the root "card" translates to "heart", and the suffix "itis" translates to "inflammation". Hence, pericarditis is an inflammation of the area surrounding the heart, or an inflammation of the outer layer of the heart, anatomically known as the pericardium. Medical terms always consist of at least one "root", although they may contain more. The root of a word is that part which contains the essential meaning of the word. An example of this was seen above in the term "pericarditis". The root of the word - card - refers to the heart, so any prefix or suffix added to the root (card) will only function to add to the specificity of that word. An example of this would be the prefix "brady", which means "slow". If "brady" is added to the root "card"...

Marketing 301

...There is a world of marketing that is build on the way consumers respond to a certain product or the way it is marketed. It comes as no surprise, then, that companies and marketing firms look at social patterns and consumer psychology to understand better how and what affects consumers to the greatest degree and what ushers them to go out an purchase whatever they end up spending their money on. Another agreed upon fact is that one of the most important contributing factors to consumer decision making is the culture that they have internalized as what defines them. Fact of the matter is that consumers are more affected by their culture than they care to admit. Other factors include location, peer group influence, income group etc. However, all these factors determine what one needs or wants to spend money on. Culture is something that subconsciously makes you need or want a particular thing. A colder location indicates to a consumer the need or want for heavy garments that will make them warm. Their culture automatically defines what that garment is going to look like. The women in Canada will wear jeans, leggings and tshirts, while women in India will be dressed in their traditional saaris. Therefore, all over the world, some indications of what the consumer wants or needs can be the same, however the purchase descisions all over the world are not the same. They vary because the culture varies, and since the culture varies, the consumers response to the same demands vary as...

Mendez, OP, School Director, Mrs. Muñoz, High School Principal, Mrs. Sandra Gratuito, English Teacher, High School Faculty and Non-teaching Staff, distinguished guests, dear parents, fellow graduates, ladies and gentlemen, Good afternoon. I’ve heard a lot of valedictory addresses and usually, if not all the time they struck me as boring and bent out of formalities. All I pray is that you never get bored as I get this chance in my life to talk in the same pedestal as those boring people (hehe) A long time ago, a man once said that it is not the years in a man’s life that matters, but it is the life in his years. My fellow graduates, what does thirteen years of Aquinian education mean to you? Is it just time that has come and gone? Is it the years that have finally come to an end? Or is it more than just that? My brothers and sisters, if that is all what they mean to you, then I am sorry that you have failed to reap the fruits of your labour. These eleven years are filled with more than just months, weeks and days of experience and learning. The last four years I have spent studying in Aquinas with you, my fellow classmates, makes me truly say that I am better than what others say I could be. In fact, we all are, whether we know it or not. As a class, we may have gone through many difficult trials, events that shattered our unity. There...

Final Essay Hum

...Part One * You are the news director of a local television station. The city council has just voted to close city parks 3 days a week to save money. Meanwhile, a major celebrity has died. The park story has greater effect on your viewers, but the celebrity death will get bigger ratings? Which do you make your lead story and why? For some unknown reason, news has become more than a center of information. It has become the platform of entertainment. Ratings have increased when the news includes celebrity highlights or “gossip.” This is where it gets hard as a news director. Trying to make the best judgment to not jeopardize ratings but to also be informative. Standing between what affects the viewer and what will bring more rating to the station. This is where as a director I would have to play it smart. There are a couple of things to keep in mind. One is the fact that there are important things going on in the city that the citizens need to be aware of. Some people work hard and as a result don’t have the time to sit down and read a newspaper even if is online. They depend solemnly on the night news. Then we have on the other side the ones that like news that pertain only about entertainment, and this is where it gets tough. In order to keep both parties happy you try to come up with something to catch the attention of both types of viewers. Having a good marketing team that learns how to capture the different viewers attention is the key to these kinds of situations...

Succeding in College

...Succeeding at Fullerton College Transitioning from high school to college can be intimidating I know this because that is what doing right now. Everything is different from the people, to the schedule, and just the surrounding. In high school I was always that student who always did good enough, that did homework here and there. I knew that I could do the work, but never really wanted to. Instead I would have rather hung out with friends, watch TV, or go play basketball. Never wanted to study or do homework towards the end of the senior year I realized that I am capable of more. Even though I averaged a 3.0, I could’ve gotten a higher GPA if I had put in more effort. If I wanted to succeed in life then I have to start putting in the time and effort, and that starts with succeeding in college. Various of students have their own plan to succeed in school, but mine it starts with setting myself goals, time management and most importantly taking advantage of student services here at Fullerton College. First of all I’m going to set myself goals not just life goals but goals in generals. Setting goals is practically a to do list, it explains to you what is need from yourself. It is going to give me direction to my life and a purpose. I feel like if I don’t set myself goals then somehow some way I’m going to start following a path made by others. Setting a goal for me is a way to fuel my ambition. For example what I really want to do in life is to have my own show, to make people...

...The terms ‘best fit’ and ‘best practice’ are used in strategic human resource management literature and are applied to the specific policy area of reward systems. Each approach attempts to explain the way that HR policies in general and reward policies in particular can lead to greater organisational effectiveness. Some commentators believe that the development of the best fit model is derived from the Harvard, Michigan and New York models. Sparrow and Hiltrop (1994) claim that these models could be classified as ‘matching models’ because of their common aim is to match the human resources strategy with that of the corporation. Thorpe and Homan (2000), argue that previous developments in the design of pay systems did not directly relate to the real priorities and problems faced by organisations. Thus, the need to devise pay systems linked to business strategy arose. The underlying premise of best fit is that a close alignment between organisational strategy and other systems, including reward, can improve organisational effectiveness. Although the idea that pay should be linked strategy is not new, it received impetus in the 1990s with works by Schuster and Zingheim (1992, 1993) and Lawler (1995) discussing the merits of ‘new pay’. Lawler (1995, p. 14) states that all organisational systems must start with business strategy because “…it specifies what the company wants to accomplish, how it wants to behave, and the kinds of performance and...

No Summer Breaks

...3/21/13 Grammar Essay Many people believe that summer break is more interesting than school, but in school you can learn more. For example, if you have all summer in school you would have a longer time for learning. Students can benefit from school because they don’t use electronics all day long. For instance, if you are sitting in front of the computer all day your brain will turn to mush or waste. The students are putting their brains to work doing schoolwork or math problems for example. Students will also get homework that keeps the students busy. If we did not have a summer break I think we should have at least holiday breaks. For example, we should have Easter, Christmas breaks, or important holidays. We should not have a summer break because we can learn more.

...Cricket a)Golden Duck- Batsman is out on the first ball he faces, scoring 0 runs. Maiden Over- An over in which no runs are scored The Long Barrier- A fielding position usually taken up by fielders on the boundary when the ball is travelling at speed or if the outfield is bumpy. Third Man- A fielding position where the fielder is behind square on the off-side, usually on the boundary however sometimes fielding close in when a spinner is bowling. b) A fast bowler would be more dangerous and likely to get a wicket if he varied his deliveries in order to keep the batsman guessing what the next ball would be which creates doubt in his mind, this could lead the batsman to play his shots timidly and feel uncomfortable about hitting out. For example, varying the length of your deliveries would cause trouble for the batsman. E.g. If a bowler kept bowling fast short pitched deliveries and then suddenly bowler a Yorker, he would catch the batsman off guard as he would have been expecting another short pitched ball, increasing the chance of bowling him out or getting him LBW. c) The correct grip is important in order to succeed when batting as it allows you to play shots with the correct technique and with a straight back. Using a correct grip also prevents wrist injuries. A correct stance is important as if you have a correct stance you are well balanced at the crease therefore you can adjust your feet quickly and play shots with a good technique.
