单选题The willingness of doctors at several major medical centers to apologize .to patients for harmful errors is a promising step toward improving the rather disappointing quality of a medical system that kills tens of thousands of innocent patients a year inadvertently. For years, experts have lamented that medical malpractice litigation is an inefficient way to deter lethal or damaging medical errors. What they noticed, simply put it, is that most victims of malpractice never sue, and there is some evidence that many patients who do sue were not harmed by a physician's error but instead suffered an adverse medical outcome that could not have been prevented. The details of what went wrong are often kept secret as part of a settlement agreement. What is needed, many specialists agree, is a system that quickly brings an error to light so that further errors can be headed off and that compensates victims promptly and fairly. Many doctors, unfortunately, have been afraid that admitting and describing their errors would only invite a costly lawsuit. Now, as described by Kevin Sack in The Times, a handful of prominent academic medical centers have adopted a new policy of promptly disclosing errors, offering earnest apologies and providing fair compensation. It appears to satisfy many patients, reduce legal costs and the litigation burden and, in some instances, helps reduce malpractice premiums. Here are some examples from colleges of the United States: at the University of Illinois, of 37 cases where the hospital acknowledged a preventable error and apologized, only one patient filed suit; at the University of Michigan Health System, existing claims and lawsuits dropped from 262 in August 2001 to 83 in August 2007, and legal costs fell by two-thirds. To encourage greater candor, more than 30 states have enacted laws making apologies for medical errors inadmissible in court. That sounds like a sensible step that should be adopted by other states or become federal law. Such laws could help bring more errors to light. Patients who have been harmed by negligent doctors can still sue for malpractice, using other evidence to make their case. Admitting errors is only the first step toward reforming the health care system so that far fewer mistakes are made. But reforms can be more effective if doctors are candid about how they went astray. Patients seem far less angry when they receive an. honest explanation, an apology and prompt, fair compensation for the harm they have suffered.

单选题Sweden has a longstanding reputation as an egalitarian country with a narrow gender gap. But a national debate about gender equality has revealed substantial dissatisfaction, with some Swedes feeling it has gone too far. Rousing controversy now is the issue of gender pedagogy, a concept that emerged in the early 2000s and typically involves challenging gender stereotypes in learning material and in avoiding treating male and female pupils in a stereotypical manner . But what has sharpened the debate in Sweden has been the argument that schools should also be gender neutral , giving children the opportunity to define themselves as neither male nor female if they wish. Kristina Henkel, a gender expert specializing in equality in schools, disputes the argument that gender pedagogy and neutrality are being foisted on Swedes. "Sweden has a long tradition of working with equality and this has had strong support among politicians, " she says, and adds that "the question of gender neutrality, or of everyone having equal rights despite their gender, has also been driven by activists at the grassroots level. " But Elise Claeson, a columnist and a former equality expert at the Swedish Confederation of Professions, disagrees. "I have long participated in debates with gender pedagogues and they act like an elite, " she says. "They tend to be well-educated, live in big cities, and have contacts in the media, and they clearly despise traditional people. " Ms. Claeson has been a vocal critic of the word "hen, " a new, gender-neutral pronoun that was recently included in the online version of the National Encyclopedia. Around the same time, Sweden"s first gender-neutral children"s book was published. The author, Jesper Lundqvist, uses hen throughout his book, completely avoiding han and hon, the Swedish words for him and her. Claeson believes that the word hen can be harmful to young children because, she says, it can be confusing for them to receive contradicting messages about their genders in school, at home, and in society at large. "It is important to have your gender confirmed to you as a child. This does not limit children; it makes them confident about their identity... Children ought to be allowed to mature slowly and naturally. As adults we can choose to expand and change our gender identities. " Last fall, nearly 200 teachers gathered in Stockholm to discuss how to avoid "traditional gender patterns" in schools. The conference was part of a research project run by the National Agency for Education and supported by the Delegation for Equality in Schools. "I work with these issues in Finland and Norway and it is clear to me that they have been inspired by the Swedish preschool — and school curricula , " says Ms. Henkel, the gender expert. But Henkel also insists that gender equality is a rights issue that cannot simply be left to the state to handle. Instead, she says, it requires the active involvement of citizens. "Rights are not something we receive and then don"t have to fight for. This is about a redistribution of power, and for that initiative and action are needed, not just fancy legislation. "

单选题To understand the marketing concept, it is only necessary to understand the difference between marketing and selling.
