基于企业诚信视角的食品安全问题研究

近年来,食品安全事故层出不穷,不少学者认为中国食品市场的监管体制不顺、监管法律不完善是食品安全事故多发的主要原因。诚然,这些都是不争的事实。然而,生产者承担的不安全成本过低,导致食品行业普遍缺乏诚信也是问题食品接连不断被生产出来的一个不容忽视的因素。因此,有必要研究抽样误差、检验误差、追溯误差对食品生产者成本的影响,进而不断创新监管工具和监管思路、改进监管技术,让不安全食品的生产者直接承担不安全食品所带来的成本,以此促使生产者为食品安全付出更多努力。     

违法侦查行为的程序性制裁效果研究——以非法口供排除规则为中心

不断出现的冤案及其背后的违法侦查问题使整个刑事司法的公信力日趋式微。学界和司法部门最高层认识到,只有通过建立非法证据排除规则,剥夺违法侦查者非法取证的利益,才能促使其依法取证。此谓程序性制裁。但是,在目前的机制下,由于我国违法侦查的发现几率极低、无法定罪的成本极小和次级制裁机制的乏力,程序性制裁根本无法成为依法取证的"激励机制"。因此,如果要使程序性制裁的威慑效果发挥作用,必须建立有效的违法侦查行为发现机制,把非法证据排除真正转变为违法侦查的成本,并使法院真正具备作出无罪判决的能力。     

论违约金的性质——以《合同法》第114条为视角

我国《合同法》第114条约定违约金的性质得由当事人自由约定。对违约金的性质没有约定或者约定不明确的,当事人可以通过补充协议的方式来约定或者明确违约金的性质。不能达成补充协议,应当通过补充性解释来确定违约金的性质。以上方法依次用尽,仍不能确定约定违约金的性质的,应当认定约定违约金的性质是赔偿性为主、惩罚性为辅。《合同法》第114条第3款是赔偿性违约金,不是惩罚性违约金。《合同法》第114条第1款“约定因违约产生的损失赔偿额的计算方法”得出的损害赔偿额是赔偿性违约金。     

论惩罚性赔偿在侵权法中的一般适用

侵权法中的惩罚性赔偿严格限定在产品责任情形,存在适用范围过窄的问题。根据威慑理论、故意侵权、民刑互动理论以及社会良性发展的现实需求,惩罚性赔偿在侵权法中应当扩张为一般适用。在符合传统补偿性赔偿的一般构成要件前提下,惩罚性赔偿还有另外两项特殊要件,即主观故意或重大过失的加重要件以及责任范围因果关系上的减轻要件。为充分发挥惩罚性赔偿的功效,侵权法中应当建立惩罚性赔偿的一般条款,并明确其构成要件,以增强该制度的实践操作性。     

Economic Insecurity,Blame, and Punitive Attitudes

This study examines the relationship between punitive attitudes toward criminals, two measures of economic insecurity and a measure of blame for stagnating incomes that targets welfare, affirmative action, and immigration. In effect, we are testing whether punitiveness toward criminals is part of a general constellation of resentment toward what Gans (1995 Gans, H. J. 1995. The war against the poor, New York: Basic Books.  [Google Scholar]) has termed the “undeserving poor” and that Garland (2001 Garland, D. 2001. The culture of control, Chicago: The University of Chicago Press. [Crossref] , [Google Scholar]) has described as the “politics of reaction.” Survey data involving 1,476 adults are assessed using OLS regression. Results indicate that blame of welfare, affirmative action, and immigration is the strongest predictor of punitiveness. Economic insecurity has variable input to punitive attitudes that depends on the measure used and the sex and race of respondents. Some evidence of an “angry White male” phenomenon is also provided by the results.

Is cooperation cost reducing? An analysis of public–public partnerships and inter-municipal cooperation in Brazilian local government

ABSTRACT

In local government systems worldwide, financial pressures have obliged local authorities to focus on cost-efficient methods for providing local services, including inter-municipal agreements and public–public partnerships. However, in comparison with municipal mergers, privatisation and other approaches to the problem, the cost impact of the cooperative provision has not yet been thoroughly examined empirically. Moreover, available empirical research has largely concentrated on waste disposal in developed countries. The present paper seeks to contribute to the empirical literature on inter-municipal agreements and public–public partnerships by comparing their impact on costs with ‘stand-alone’ provision in a range of non-waste local services. In contrast to the bulk of existing studies, our analysis takes place in a developing country context by examining Brazilian local government over the period 2013/15. We found that – on the whole – cooperative provision is less expensive than the ‘stand-alone’ provision for the services studied. Our results can be explained by the size and composition of the population, together with the politics for cooperation.     

Weight of authorship evidence with multiple categories of stylometric features: A multinomial-based discrete model

This study empirically demonstrates the efficacy of a two-level Dirichlet-multinomial statistical model (the Multinomial system) for computing likelihood ratios (LR) for linguistic, textual evidence with multiple stylometric feature types with discrete values. The LRs are calculated separately for each feature type, namely, word, character and part of speech N-grams (N = 1,2,3), which are combined as overall LRs through logistic regression fusion. The Multinomial system’s performance is compared with that of a previously proposed system with the cosine distance (the Cosine system) using the same data (i.e., documents collated from 2160 authors). The experimental results show that: (1) the Multinomial system outperforms the Cosine system with the fused feature types by a log-LR cost of ca. 0.01 ～ 0.05 bits; and (2) the Multinomial system is more advantageous in performance with longer documents than the Cosine system. Although the Cosine system is more robust overall against the sampling variability arising from the number of authors included in the reference and calibration databases, the Multinomial system can achieve reasonable stability in performance; for example, the standard deviation value of the log-LR cost becomes lower than 0.01 (10 random samplings of authors for the reference and calibration databases) with 60 or more authors in each database.     

国家赔偿费用支付方式存在的问题及解决办法

我国现行国家赔偿法对国家赔偿费用支付方式的规定,在落实中存在若干问题。建议从以下几个方面对其予以完善：一是建立统一的国家赔偿基金;二是由申请人直接向国家赔偿基金管理部门申请赔偿;三是建立公正合理的国家赔偿评估机制;四是限制国家赔偿基金管理部门的审查权。     

成本收益理论：腐败与反腐败的机理

腐败者在进行腐败前大都要对自己的行为所可能带来的收益与可能带来的损失进行比较和衡量,即考虑通过腐败究竟能取得什么样的收益和付出什么样的代价？这就是收益与成本的关系。对于每一个“理性的经济人”来说,只有当腐败收益大于腐败成本时,权力拥有者才会铤而走险并运用其手中的权力实施腐败行为;反腐败同样存在成本与效益的问题。腐败的成本收益和反腐败的成本收益,两者有所区别同时也相互依存,腐败者的收益往往包含于反腐败所能得到的收益中,而反腐败成本的提高往往为了提高腐败者的成本。因此想有效的控制或遏制腐败,就应当从提升腐败成本和降低腐败收益,甚至从减少反腐败成本等方面进行全方位的制度性建设。
