农业强国建设及其关联问题

加快建设农业强国,要高度重视保障粮食和重要农产品稳定安全供给的重要性和紧迫性,但这是建设农业强国的底线要求,不是全部主要任务。保障粮食和重要农产品稳定安全供给是个系统工程,不可顾此失彼,要注意强化产业链供应链思维。通过分析巴西在保障粮食安全问题上的教训提出：解决粮食安全问题不仅“饭碗应该主要装中国粮”,还要注意这些粮源必须“自主可控”;加快建设农业强国必须同巩固拓展脱贫攻坚成果、促进工农城乡收入差距合理化结合起来;推进农业组织结构创新要注意依托双层经营体制发展农业,带动小农户合作经营、共同增收。当前加快建设农业强国时不我待,要注意推进相关研究强化包容互动。     

社会转型背景下凉山彝族传统婚姻文化变迁研究

从“整体主义”视角出发,综合观念、制度、礼仪、行为等方面视凉山彝族婚姻文化为一个有机整体,将其置于凉山彝族社会转型的特定背景进行观照。基于现有婚姻文化研究成果,梳理中华人民共和国成立以来特别是本世纪以来凉山彝族婚姻文化的变迁脉络与变迁内容,分析变迁中出现的积极趋势与负面问题,形成对凉山彝族传统婚姻文化及其变迁的整体性认识,为凉山涉及婚姻文化的移风易俗治理实践提供参考。     

Comparison of Confidence Intervals on Between Group Variance in Unbalanced Heteroscedastic One-Way Random Models

A computer algorithm for computing the alternative distributions of the Wilcoxon signed rank statistic under shift alternatives is discussed. An explicit error bound is derived for the numeric integration approximation to these distributions.

A nonparametric process control procedure in which the standard CUSUM procedure is applied to the Wilcoxon signed rank statistic is discussed. In order to implement this procedure, the distribution of the Wilcoxon statistic under shift of the underlying distribution from its point of symmetry needs to be computed. The average run length of the nonparametric and parametric CUSUM are compared.     

Modelling small and medium enterprise loan defaults as rare events: the generalized extreme value regression model

A pivotal characteristic of credit defaults that is ignored by most credit scoring models is the rarity of the event. The most widely used model to estimate the probability of default is the logistic regression model. Since the dependent variable represents a rare event, the logistic regression model shows relevant drawbacks, for example, underestimation of the default probability, which could be very risky for banks. In order to overcome these drawbacks, we propose the generalized extreme value regression model. In particular, in a generalized linear model (GLM) with the binary-dependent variable we suggest the quantile function of the GEV distribution as link function, so our attention is focused on the tail of the response curve for values close to one. The estimation procedure used is the maximum-likelihood method. This model accommodates skewness and it presents a generalisation of GLMs with complementary log–log link function. We analyse its performance by simulation studies. Finally, we apply the proposed model to empirical data on Italian small and medium enterprises.     

论反垄断私人诉讼原告资格的二元化

我国当前民事诉讼立法对适格原告的要求过于严格,无法契合反垄断私人诉讼的特殊需求,导致此类纠纷中私人利益和公共利益得不到有效的司法救济。借鉴域外经验,结合自身国情,构建我国反垄断私人诉讼原告资格制度至关重要。私人提起反垄断诉讼因其利益指向的不同有着反垄断私人诉讼之“公益诉讼”和“私益诉讼”的分化。在起诉者利益指向分化下,二者面临着截然不同的困境和需求,由此在原告资格的确立上也应有所差异,即反垄断私人诉讼适格原告二元化。     

Generational conflict and provisions for the elderly in Hong Kong: The relevance of position‐based interest and values

Respect for the elderly and hence the associated rights support a generational contract. Nevertheless, the case of the recent debate on the universal retirement scheme in Hong Kong has raised concerns about its strength. We identify relevant items from the sixth wave of the World Values Survey to explore the orientations of different generations toward others. The analysis shows differences between younger and older generations. Regression analyses show that values are not significant in explaining the differences, but various positions, including sex, marital status, and education, and perceptions of the elderly are relevant. Such differences across generations might weaken the generational contract and potentially engender conflicts as shown in the recent debate about the retirement scheme. We suggest short‐ and long‐term interest calculations, informed by their positions, play a more significant role in policy discussions and decisions, rather than simply appealing to values.     

Side-by-Side on Stage - Music and Drama Form a Bridge between Acting Students and People with Dementia in an Intergenerational Group Work

ABSTRACT

This article presents an intergenerational music and drama therapy groups comprised of twelve people with dementia residing in a nursing home and twelve acting students from the community.

The qualitative research aimed to explore the students’ attitudes towards elderly people, and to understand the role of creative arts therapies in facilitating intergenerational relationships. Qualitative content analysis of students’ weekly reports and questionnaires revealed the gradual process of connection between the students and people with dementia. Engaging in a creative act helped the students to discover the strengths and abilities of people with dementia and to see beyond the disease.     

Love,Stigma, and Resistance: “Therapeutic Microaggressions” in a Prisoners' Wives' Support Group

This article derives from ethnographies of therapeutic interventions in a support group for prisoners' wives in Israel. The study's main inductive findings reveal that love and the emotion work of prisoners' wives are constructed as the primary site for achieving the clinical objective: modifying the prisoners' wives' spoiled self and encouraging their adoption of a psychological self. The findings reveal a dramatic clash between the therapeutic emotion work of love that the group facilitators proposed and the collectivist emotion work to which the prisoners' wives subscribed. These forms of emotion work are associated with ethnic hierarchies and experiences of stigmatization by the prisoners' wives during the therapeutic sessions. In this context, the article suggests the concept of “therapeutic microaggressions” to describe how interactions in clinical sessions can reinforce inequality.     

基于交叉效率DEA与群体共识的区间乘性语言偏好关系群决策

针对区间乘性语言偏好关系群决策问题，提出了一种基于交叉效率DEA和群体共识的群决策方法。首先，提出乘性语言偏好关系导出函数的定义，并构建产出导向的DEA模型，证明了一致性乘性语言偏好关系的DEA效率得分与排序向量之间存在比例关系。在此基础上，建立基于理想值的交叉效率DEA模型，提出乘性语言偏好关系的通用排序方法。同时，基于群体共识建立目标规划模型来计算各语言偏好关系的权重系数。最后，利用Monte Carlo随机模拟的方法对群体语言偏好空间进行统计分析，得到群决策期望排序向量及其可信度。算例分析表明本文方法能够有效的避免信息损失，具有较强的适用性和较高的可信度。     

大学生利益诉求与表达机制构建研究

新时期高校学生的利益诉求与表达机制逐步呈现多元化趋势，这就要求高校学生思想工作走向更进一步的精细化管理，将高校学生利益诉求与表达机制列入精细化管理内容。但是，近年来高校学生的利益诉求与表达机制构建缺失，导致校园群体纠纷事件屡见不鲜，严重影响和谐校园环境的构建。通过调查高校学生常见的利益诉求方式及其存在障碍，分析学校学生利益诉求类型及其现状，建立学生利益诉求机制的对策，做到以生为本、服务学生。
