对大学生产生重大影响的社会思潮

西方自由主义、拜金主义、享乐主义、个人主义、功利主义等是影响当代大学生思想的主要社会思潮。大学生易受不良思潮影响的原因在于缺乏历史知识,政治理论学习不深入,同时受西方思想文化的长期影响。所以要正确引导学生自觉学习政治理论,系统全面了解社会发展史,树立正确的人生观和价值观。同时网络、影视、报刊等媒体要有一个正确的导向,给大学生成长营造出一个好的成长环境。     

英语重复现象的语用功能

英语重复现象的功能并不局限于对某种信息的强调,还可在不同的交际环境下起不同的语用功能,具体表现为:表示同意、要求对方予以澄清、延缓作答时间、连接话题、表达激情等.     

浅析语义模糊与语用模糊

国内外许多学者和研究人员对语义模糊进行了一系列比较深入的研究,而对于言语交际中存在的语用模糊现象的研究并不多见,因此对于二者的对比分析有一定的必要性。本文首先区别了语义模糊和语用模糊的概念,接着具体讨论了区分二者的方法,然后分别从谈话者和听话者角度论述了生成语义模糊和语用模糊的手段。本文的目的主要是澄清语义模糊和语用模糊的概念,并引起大家对语用模糊的更多关注。     

Group Selection and the Limits to Altruism

Several evolutionary mechanisms have been identified in the literature that would generate altruism in humans. The most powerful (except for kin selection) and most controversial is group selection, as recently analyzed by Sober & D.S. Wilson. I do not take a stand on the issue of the existence of group selection. Instead, I examine the level of human altruism that could exist if group selection were an engine of human evolution. For the Sober & Wilson mechanism to work, groups practicing altruism must grow faster than other groups. I call altruistic behavior that would lead to faster growth efficient altruism. This often consists of cooperation in a prisoner's dilemma. ltruistic acts such as helping a temporarily hungry or injured person would qualify as efficient altruism. Efficient altruism would also require monitoring recipients to avoid shirking. Utilitarianism would be an ethical system consistent with efficient altruism, but Marxism or the Rawlsian system would not. Discussions of efficient altruism also help understand intuitions about fairness. We perceive those behaviors as fair that are consistent with efficient altruism. It is important to understand that, even if humans are selected to be altruistic, the forms of altruism that might exist must be carefully considered and ircumscribed.     

中美邀请言语行为对比研究

邀请言语行为是语言中不可缺少的部分,对于日常交际有着一定的影响;邀请言语行为与民族文化有着密切的联系,体现出不同民族的文化特色,遵循着不同的民族礼貌规范;不了解邀请言语行为的规范及其背后的民族文化,就会导致跨文化交际失误;外语教学中培养学生得体的邀请言语行为能力,可以帮助他们减少语用失误。     

Egalitarianism under population change: Age structure does matter

We study the compatibility of the optimal population size concepts produced by different social welfare functions and egalitarianism meant as “equal consumption for all individuals of all generations”. Social welfare functions are parameterized by an altruism parameter generating the Benthamite and Millian criteria as polar cases. The economy considered is in continuous time and is populated by homogeneous cohorts with a given life span. Production functions are linear in labor, (costly) procreation is the unique way to transfer resources forward in time. First, we show that egalitarianism is optimal whatever the degree of altruism in “perpetual youth” model, that is when lifetime span is finite but age structure does not matter: in this case egalitarianism does not discriminate between the social welfare functions considered. Then we show that, when life span is finite but age structure matters, egalitarianism does not arise systematically as an optimal outcome. In particular, in a growing economy, that is when population growth is optimal in the long-run, this egalitarian rule can only hold when the welfare function is Benthamite. When altruism is impure, egalitarianism is impossible in the context of a growing economy. Either in the Benthamite or impure altruism cases, procreation is never optimal for small enough life spans, leading to finite time extinction and maximal consumption for all existing individuals.     

基于关联理论解读有意沉默

为了研究有意沉默在会话中的语用意义,以英汉会话语段中的有意沉默为研究对象,依据Sperber和Wilson的关联理论,从有意沉默的信息意图和交际意图,以及有意沉默的关联性与语境效果两点入手对有意沉默进行认知语用分析.对有意沉默进行认知语用解读和分析的目的在于帮助我们进一步理解有意沉默,并在以后的会话中能更好地领会并运用有意沉默,使交际能够顺利进行.     

Evaluating intergenerational risks

Climate policies have stochastic consequences that involve a great number of generations. This calls for evaluating social risk (what kind of societies will future people be born into) rather than individual risk (what will happen to people during their own lifetimes). We respond to this call by proposing and axiomatizing probability adjusted rank-discounted critical-level generalized utilitarianism (PARDCLU) through a key axiom ensuring that the social welfare order both is ethical and satisfies first-order stochastic dominance. PARDCLU yields a new useful perspective on intergenerational risks, is ethical in contrast to discounted utilitarianism, and avoids objections that have been raised against other ethical criteria. We show that PARDCLU handles situations with positive probability of human extinction and is linked to decision theory by yielding rank-dependent expected utilitarianism—but with additional structure—in a special case.     

语言模因作为语用策略的顺应性分析

语言模因是一种语用策略。在日常交往中,为了满足特定的交际需要,说话人可借助模因这一语言载体来顺应交际者的物理世界、社交世界和心理世界,从而达到理想的交际效果。     

语用失误及其对大学英语听说课教学的启示

外语教学的主要目的是培养和发展学生运用外语进行交际的能力,这一观点已被人们广泛接受。语用失误包括语用语言失错和社交语用失误。避免语用失误,应培养学生的语境意识、语用意识、跨文化交际意识,并改革课程考核办法。
