农村土地流转制度问题探析

土地是农业最基本的生产要素,土地制度也是三农问题的核心。我国目前的农村土地制度是在家庭联产承包责任制基础上形成的,随着环境的变化和市场经济的发展,急需建立和完善农地流转制度,新制度经济学的产权理论和交易成本理论提供了对我国目前农地流转问题和对策的分析视角。     

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。     

民事诉讼证据交换制度的立法探讨

证据交换的正当性虽然无可置疑,但其被规避适用却是实务中的普遍现象。设置证据交换制度有诉讼效率的考量,但其首要的价值目标却是公平和公正。审判效率得以提高的秘密不在于证据交换本身,而在于证据交换制度所依存的具有不可逆性的二元性诉讼结构。在制度层面上,司法解释与《民事诉讼法》的不兼容及司法解释技术自身的问题应当予以检讨。完整的具有实效性和可操作性的证据交换规则的确立包括两个大的方面：一是包含有实体性因素的证据交换规则;二是包含有程序性因素的证据交换规则。     

基于中阿合作视域的宁夏文化“走出去”战略探析

在中阿合作的进程中,宁夏文化的"走出去"是极其重要的,这是中阿合作的基础性和根本性工作。文化的"走出去",势必会深化中阿合作的内涵,丰富其内容,推动其不断走向更高的阶段,取得新的、更大的成效。因此,要明确中阿合作中宁夏文化"走出去"的重点领域,也要发挥政府在其中的主导作用。

Antecedents of Psychological Empowerment: A Study of Greek Employees in Municipalities

ABSTRACT

Psychological empowerment has received a burgeoning attention among scholars and practitioners in the last decades. However, little is known about its antecedents in the public sector, and even more in municipalities. The present study attempts to fill this gap by examining the relationship of leader-member exchange (LMX), role conflict and role ambiguity with employees’ psychological empowerment. Data were collected from 210 administrative employees of nine Greek municipalities. Results supported our hypotheses that these three factors constitute important antecedents of such employees’ psychological empowerment. Theoretical and practical implications were also discussed.     

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.     

‘A second wife is not really a wife’: polygyny,gender relations and economic realities in Tajikistan

While polygyny in Tajikistan existed before the collapse of the Soviet Union in 1991 and has been a phenomenon of growing importance since Independence, it is still forbidden by law. To understand this renewal, I do not look at polygyny as a sign of religiousness, but as a form of patriarchal bargain in which women (who often experienced former matrimonial disjuncture) may have a greater power of decision in the spousal relations. I will explore women's points of view, from which polygyny is a strategy to accessing the symbolic and material resources they lack. I then explore the conditions to which becoming a second wife is possible: women's own resources, be they material, symbolic, familial, appear as of crucial importance in this accession to the status of being married anew.
