Subjective utility with upper and lower probabilities on finite states

This article is concerned with thresholds of discrimination of preference judgments under uncertainty. We establish an axiomatic characterization for a threshold representation, where thresholds are represented by inexact measurement of subjective probabilities, i.e., upper and lower probabilities. Since upper and lower probabilities need not be additive, the representational form adopts the Choquet integration.     

论间接故意与过于自信的过失 --理论与实际的矛盾

间接故意与过于自信的过失是犯罪构成中主观方面最容易混淆的两种罪过,本文对这两种罪过进行了系统的比较,并对两者的实际操作中所体现的矛盾进行了分析,最后文章对矛盾提出了解决的方案。     

刑事违法观与犯罪构成关系论

按照主观违法论而加以建构的传统犯罪构成理论有别于按客观违法论建构的大陆法系犯罪论体系,两者有着不同的研究进路和研究方法。主观违法论强调有责之违法,行为人的主观罪过、客观的危害行为、刑事责任能力都是违法的构成要素,这种因人而异的违法观不能很好地为司法实践提供理论根据。从主观违法论立场出发,我们不可能从构成要件其中一个方面单独地判断违法性是否存在,传统犯罪构成理论将犯罪构成要件定位于反映行为社会危害性的事实特征,因此,犯罪构成只反映定罪结论,不反映定罪过程。

Subjective probabilities and utility with event-dependent preferences

This article generalizes Savage's theory to include event-dependent preferences. The state space is partitioned into finitely many events. The induced preferences over consequences are assumed independent of the underlying states within, but not across, these events. This results in an additively separable representation of preferences over acts. The dependence of the preference relation over consequences on the events is represented by event-dependent mappings of the set of consequences onto itself. Given these mappings, the preferences on acts are represented by the expectation of event-dependent utilities on the consequences with respect to unique subjective probabilities on the states.Helpful discussions with David Schmeidler are gratefully acknowledged.     

Making ends meet: perceptions of poverty in Sweden

During the era after the Second World War, Sweden has built a welfare system based on labor market participation and income maintenance. Low unemployment and decent wages are supposed to guarantee people a labor market income or income maintenance, which in turn should provide a proper standard for everyone. However, a rapid increase in unemployment and economic problems have made the future of the Swedish welfare state more uncertain than ever. These circumstances have, among other things, led to the suggestion that Sweden should abandon the income maintenance policy and create a social policy system with the more limited ambition of guaranteeing everyone a minimum income. In that case, one central question must be answered: what constitutes a decent minimum income in today's Sweden? Where should we draw the poverty line under which people will not be forced to live? These questions are central in the current debate. The consensual poverty line method is used in this article to derive a poverty line relevant for today's Sweden. The results shows that more than every fifth household has an income below the consensual poverty line. That is, they have an income that most Swedes would argue is too low to make ends meet. The level of the consensual poverty line was compared with the National Board of Health and Welfare's guidelines for social assistance. The consensual poverty line was shown to be more generous to small households and the norm for social assistance was more generous to larger households. Finally, the expenditure for guaranteeing all Swedish household a minimum income equal to the consensual poverty line was estimated: more than SEK 25 billion per year. The results in the article casts serious doubt on the ability of the Swedish welfare state to secure a decent income to all citizens.     

知识缺失还是知识自负？知识水平对公众食品安全信心的影响研究

通过对中国10个城市成年受访者的调查,发现公众对当前食品安全问题的感知风险水平较高,反映其对食品安全形势较担忧,且对政府食品安全管理部门存在信任危机。不过公众的感知控制力较高,普遍认为自己有保障自身食品安全的能力,因此在日常的食品消费中仍然有较高的信心。研究证实中国公众在食品安全的知识层面存在着知识自负现象,公众自我评估的主观知识水平显著高于实际拥有的客观知识水平,且真正对公众食品安全信心产生影响的是公众的主观知识水平。这说明传统缺失模型所倡导的以科普、辟谣为主要形式的致力于教育公众、提升公众客观知识水平的行动能够取得的效果可能非常有限;而公众的主观知识水平和感知控制力的提升能有效提振公众的食品安全信心。     

Coherent decision analysis with inseparable probabilities and utilities

This article explores the extent to which a decision maker's probabilities can be measured separately from his/her utilities by observing his/her acceptance of small monetary gambles. Only a partial separation is achieved: the acceptable gambles are partitioned into a set of belief gambles, which reveals probabilities distorted by marginal utilities for money, and a set of preference gambles, which reveals utilities reciprocally distorted by marginal utilities for money. However, the information in these gambles still enables us to solve the decision maker's problem: his/her utility-maximizing decision is the one that avoids arbitrage (i.e., incoherence or Dutch books).     

青海话中的词缀"头"

青海话中的词缀“头”除了有与汉语普通话词缀“头”相同的特点外,还能够放在动词词根和形容词词根语素的后面,构成一个新的名词,表示某事是否值得做或必要性的主观评价,也可以指对象或状态;这种方式构成的名词是一个开放的系统,只存在于具体语境之中。文章还进一步探讨了这种用法的起源,并与其它方言中的词缀“头”作了对比分析。     

冯雪峰论:“修正主义文艺“批判运动人物检讨(之一)

冯雪峰是“修正主义文艺”批判运动第一阶段（ １９５６～ １９６２）主要的批判对象．作 为唯一的参加过长征的左翼文艺理论家,冯雪峰于１９５７年遭遇清算,除了他那不合时宜的革命 现实主义理论的启蒙倾向,还有一个重要的原因,就是１９世纪３０年代已然形成、长期以来没 能解决的宗派主义从中作祟．
