In a bustling city hospital,Dr.Smith,a seasoned physician,was having a conversation with Mr.Johnson,a prominent lawyer.Their dialogue revolved around the complexities of their respective professions and the ethical dilemmas they often faced.Dr.Smith began the conversation by expressing his concerns about the increasing burden of medical malpractice lawsuits.Mr.Johnson,as a doctor,Im constantly worried about making a mistake that could lead to a lawsuit.Its stressful,and it sometimes makes me secondguess my decisions.Mr.Johnson nodded in understanding.I can see how that would be a concern,Dr.Smith. As a lawyer,I often deal with clients who feel wronged by professionals like yourself.Its a delicate balance between seeking justice and understanding the pressures that come with your job.The doctor sighed,Yes,and its not just about the fear of lawsuits.Its about doing whats best for the patient.Sometimes,the most ethical course of action isnt the most popular one.I completely agree,Mr.Johnson replied.In law,we also face ethical dilemmas.For instance,should I represent a client I believe is guilty?Its a constant struggle between personal morals and professional obligations.Dr.Smith leaned back in his chair,Thats a tough one.But at least you have the luxury of choosing your clients.In medicine,we cant turn away a patient in need,even if it means walking a fine ethical line.The lawyer nodded thoughtfully,True,but I think we both have a common goal:to serve others and uphold a standard of integrity.Its just that the path to that goal can be fraught with challenges.The conversation continued,with both professionals sharing anecdotes from their careers. They discussed the importance of clear communication,both with clients and patients, and the need for empathy in their roles.Empathy is crucial in medicine,Dr.Smith emphasized.It helps build trust with patients and makes them feel heard and understood.Absolutely,Mr.Johnson concurred.In law,empathy helps me connect with my clients on a deeper level,allowing me to better represent their interests.As their discussion drew to a close,both Dr.Smith and Mr.Johnson acknowledged the unique challenges and rewards of their professions.They agreed that while their paths were different,the commitment to ethical practice and service to others was a common thread that bound them together.。

⼩编为⼤家提供2019年考研英语⼀翻译真题及答案解析，⼀起看看吧！ 2019考研英语⼀翻译真题 It wasn’t until after my retirement that I had the time to read scientific papers in medical journals with anything like close attention. Until then, I had, like most doctors, read the authors’ conclusions and assumed that they bore some necessary relation to what had gone before. I had also naively assumed that the editors had done their job and checked the intellectual coherence and probity of the contents of their journals. It was only after I started to write a weekly column about the medical journals, and began to read scientific papers from beginning to end, that I realized just how bad — inaccurate, misleading, sloppy, illogical — much of the medical literature, even in the best journals, frequently was. My discovery pleased and reassured me in a way: for it showed me that, even in advancing age, I was still capable of being surprised. I came to recognize various signs of a bad paper: the kind of paper that purports to show that people who eat more than one kilo of broccoli a week were 1.17 times more likely than those who eat less to suffer late in life from pernicious anaemia.46) There is a great deal of this kind of nonsense in the medical journals which, when taken up by broadcasters and the lay press, generates both health scares and short-lived dietary enthusiasms. Why is so much bad science published? A recent paper, titled ‘The Natural Selection of Bad Science’, published on the Royal Society’s open science website, attempts to answer this intriguing and important question. According to the authors, the problem is not merely that people do bad science, as they have always done, but that our current system of career advancement positively encourages it. They quote ananonymous researcher who said pithily: ‘Poor methods get results.’ What is important is not truth, let alone importance, but publication, which has become almost an end in itself. There has been a kind of inflationary process at work: 47) nowadays anyone applying for a research post has to have published twice the number of papers that would have been required for the same post only 10 years ago. Never mind the quality, then, count the number. It is at least an objective measure. In addition to the pressure to publish, there is a preference in journals for positive rather than negative results. To prove that factor a has no effect whatever on outcome b may be important in the sense that it refutes a hypothesis, but it is not half so captivating as that factor a has some marginally positive statistical association with outcome b. It may be an elementary principle of statistics that association is not causation, but in practice everyone forgets it. The easiest way to generate positive associations is to do bad science, for example by trawling through a whole lot of data without a prior hypothesis. For example, if you took 100 dietary factors and tried to associate them with flat feet, you would find some of them that were associated with that condition, associations so strong that at first sight they would appear not to have arisen by chance. Once it has been shown that the consumption of, shall we say, red cabbage is associated with flat feet, one of two things can happen: someone will try to reproduce the result, or no one will, in which case it will enter scientific mythology. The penalties for having published results which are not reproducible, and prove before long to be misleading, usually do not cancel out the prestige of having published them in the first place: and therefore it is better, from the career point of view, to publish junk than to publish nothing at all. A long list of publications, all of them valueless, is always impressive. 48)Attempts have been made to (control this inflation命题⼈改编为curb this kind tendency),(for example by trying, when it comes to career advancement这部分被出题⼈删除), to incorporate some measure of quality as well as quantity into the assessment of an applicant’s published papers. This is the famed citation index, that is to say the number of times a paper has been quoted elsewhere in the scientific literature, the assumption being that an important paper will be cited more often than one of small account. 49) This would be reasonable enough if it were not for the fact that scientists can easily arrange to cite themselves in their future publications, or get associates to do so for them in return for similar favors. Boiling down an individual’s output to simple, objective metrics, such as number of publications or journal impacts, entails considerable savings in time, energy and ambiguity. Unfortunately, the long-term costs of using simple quantitative metrics to assess researcher merit are likely to be quite great. 50) If we are serious about ensuring that our science is both meaningful and reproducible, we must ensure that our institutions incentivize that kind of science. In other words, what we need is more emphasis on personal contact and even nepotism in the way careers are advanced: but tell it not in Gath, publish it not in the streets of Askelon; lest the daughters of the Philistines rejoice… 46.

1. Recently, one of us had the opportunity to speak with a medical student about a research rotation that the student was planning to do. She would be working with Dr. Z, who had given her the project of writing a paper for which he had designed the protocol, collected the data, and compiled the results. The student was to do a literature search and write the first draft of the manuscript. For this she would become first author on the final publication. When concerns were raised about the proposed project, Dr. Z was shocked. "l thought I was doing her a favor," he said innocently, "and besides, I hate writing!"2. Dr. Z is perhaps a bit naive. Certainly, most researchers would know that the student's work would not merit first authorship. They would know that "gift" authorship is not an acceptable research practice. However, an earlier experience in our work makes us wonder. Several years ago, in conjunction with the grant from the Fund for the Improvement of Pott Secondary Education (FIPSE), a team of philosophers and scientists at Dartmouth College 2 ran a University Seminar series for faculty on the topic "Ethical Issues in scientific Research."At one seminar, a senior researcher (let's call him Professor R) argued a similar position to that of Dr. Z. In this case Professor R knew that "gift" authorship, authorship without a significant research contribution, was an unacceptable research practice. However, he had a reason to give authorship to his student.The student had worked for several years on a project suggested by him and the project had yielded to publishable data. Believing that he had a duty to the student to ensure a publication, Professor R had given the student some data that he himself had collected and told the student to write it up. The student had worked hard, he said, albeit on another project, and the student would do the writing. Thus, he reasoned, the authorship was not a "gift."3. These two stories point up a major reason for encouraging courses in research ethics: Good intentions do not necessarily result in ethical decisions. Both of the faculty members in the above scenarios "meant well." In both cases, the faculty members truly believed that what they were doing was morally acceptable. In the first case, Dr. Z's indefensible error was that he was unaware of the conventions of the field.In particular, he seemed blissfully oblivious to the meaning of first authorship. In the second case, Professor R was do ng what he thought best for the student without taking into consideration that moral. ty is a public system and that his actions with regard to a single student have public consequences for the practice of science as a profession.4. Well-meaning scientists, such as those just mentioned, can, with the best of intentions, make unethical decisions. In some cases, such decisions may lead individuals to become embroiled in cases of misconduct. A course in research ethics can help such scientists to appreciate that it is their responsibility to know professional conventions as well as to understand the public nature of morality.1. 最近，我们当中的一员有机会与一名医科学生谈论她正计划要做的一个实验室轮转项目。

How to Handle the StressNowadays more and more people have been under various stresses and there has been an increase in stress-related diseases among employees and students. This phenomenon has aroused immediate concern and widespread discussion among the general public. From my perspective, the resources of stresses can be from our work, family and also from the society, and learning how to deal with stresses has far-reaching significance to our body health.As a matter of fact, some solutions to reduce stresses can be illustrated below. The first one that comes to my mind readily is to share our stress with others. It can be enormously helpful because we may feel quite relaxed after talking to others and things even turn better if we get any valuable suggestions from them. What’s more, making time for fun such as listening to music and watching movies may be good medicine. Additionally, it is also a great way to reduce anxiety to do a large number of physical activities.From what has been discussed above, I strongly believe that we should know how to reduce enormous stress because it poses a general threat to human body health. As a common employee, I often feel immense stress at work. In those cases, I always tried to talk with my close friends to hear their advice or just listen to my favorite music. Only by having both mental and physical health can we hope to do our job well in the future?My favorite way of keeping fitsObservations and research findings indicate that people are increasingly concerned abo ut keeping fits. The importance people attach to it and the rapid development of related s ervices are the signs of this.There are several ways of keeping fits. Dieting should be fundamental to one’s heal th. We are facing more choice than ever before. Therefore, we should be cautious to sele ct the proper foods and to control the reasonable amount. What’s more, taking experienc e is another essential way. In addition, nobody is exposed to be considered as healthy in mental disorder, so that keeping mental health is also important.As for me, I am exerting all my strength on keeping my fits, by taking reasonable di eting and proper exercise and by remaining in good mind. In particular, I like jogging, m ore than four times per week, and approximately ．Nowadays, more and more people are concerned about the problem of environmental protection, for the pollution has brought us so many bad influences. It is important for us to r ealize that it is everyone’s duty to protect our environment.To cope with this nation-wide problem, our government has started to take a series of effective measures. The most effective way is to save energy and reduce carbon emission. Because every year billions of tons of carbon dioxide are emitted into the air, which in part, result in the global warming and climate changing.For me, I am trying to make my own contributions. Firstly, I go to work by bus instead of driving. Secondly, I am getting to form the habit of saving water and electricity. For example, when I brush my teeth and wash my hands, I will never leave the water running again. What's more, I even recommend our relatives and friends to do so. By now my ways have been working perfectly and efficiently.Nowadays,with the rapid development of computer technology,in particular,the artifici al intelligence(AI),the application of senior AI in the future has aroused a considerable world-wide concern.It is recently reported that in a ground-breaking fight between man and AI,the world champion of game Go was mercilessly de feated by Deep Mind Alpha Go,a product from Google,which gives rise to some people ’s fear toward advanced AI in future practice.And they take it for granted that human being would probably be totally controlled by machine.As far as AI is concerned,I am fully convinced that we are supposed to maintain an obje ctive and positive attitude toward the emerging issue of artificial intelligence.It is know n to all that AI is nothing but the simulation of information on the process of conscious thinking,or in another words,it’s something that subjects to its inventor’s design awaren ess.Consequently,as long as we are fully conscious of its possible disadvantages,certai n restrictions can be input into the program to avoid potential disastrous occurrences.Ad ditionally,it is well hoped that AI and intelligent machines can possibly free human labo rs from virtually all kinds of jobs.In that case/Above-mentioned discussion can safely lead to the conclusion that what we are supposed to do i s but to learn to get along with the inevitable development of computer technology and t o adapt to the updated social structure changed by AI.What make happy couple happy?With the rapid development of modem society,an increasing number of people are c oncerned about the problem of the relationship between a husband and wife in our societ y.Not only the government but also the public have to pay more attention tothis phenomenon .Undoubtedly,it has brought about a great influence on people's work and living. Based on what has been discussed so far,it follows that some eflective solutions should be found to deal with the problem of the relationship between two people.On the one ha nd,the couples had better understand each other's daily habits so that they can form the s ame interests,which can make couples become happy on the other hand,no matter how close the relationship is between two people,we should give enough room to each other because keeping appropriate distance can make the two people more comfortable.Only in these ways can we solve this problem successfully and eficctivcly.As far as I am concerned,no relationship will be free of difficulty or conflict.That happ y couples live happily is because that they are able to both apologize and forgive facing with difficulty or conflict.。

Strategic Management Journal, Vol. 18:7, 509–533 (1997)The dynamic capabilities framework analyzes the sources and methods of wealth creation and capture by private enterprise firms operating in environments of rapid technological change. The competitive advantage of firms is seen as resting on distinctive processes (ways of coordinating and combining), shaped by the firm’s (specific) asset positions (such as the firm’s portfolio of difficult-to-trade knowledge assets and complementary assets), and the evolution path(s) it has adopted or inherited. The importance of path dependencies is amplified where conditions of increasing returns exist. Whether and how a firm’s competitive advantage is eroded depends on the stability of market demand, and the ease of replicability (expanding internally) and imitatability (replication by competitors). If correct, the framework suggests that private wealth creation in regimes of rapid technological change depends in large measure on honing internal technological, organizational, and managerial processes inside the firm. In short, identifying new opportunities and organizing effectively and efficiently to embrace them are generally more fundamental to private wealth creation than is strategizing, if by strategizing one means engaging in business conduct that keeps competitors off balance, raises rival’s costs, and excludes new entrants.
