Analysing facilitating and hindering factors for implementing gender equality interventions in R&I: Structures and processes

This article analyses the facilitating and hindering factors that have affected the implementation of gender equality interventions in research and innovation in Europe. It applies the evaluation framework developed in the EFFORTI project that recognizes the complexity of evaluating gender equality interventions in R&I, the importance of factoring in context to any sound evaluation as well as the need to distinguish between the design and implementation of interventions in evaluations. It is based on the analysis of 19 empirical case studies carried out throughout Europe and focuses on those structural and procedural factors that have either facilitated or hindered the implementation process of these interventions. Findings include how the governance framework; top-management commitment; bottom-up participation; framing synergies with other initiatives, strategies for tackling resistance; resources; sustainability of actions; gender competence, experience and knowledge and transparency, targets, standards and monitoring; and accessible data and information all contributed to the successful implementation of the interventions.     

竞争中的参考价格效应及承诺

消费者的社会感知会影响其对产品和品牌的评价。当消费者进行购买选择时,经常会受到参考价格效应的影响。而广告和价格不仅是企业经常要考虑的重要决策,还会对参考价格产生重要影响。为此,一个值得研究的的问题是：在考虑参考价格效应的情况下,企业该怎样确定其动态广告和价格策略？
为了研究该问题,本文构建了一个广告和价格的动态模型,来研究一个双寡头市场环境下两个寡头企业的价格和广告决策,并以此分析参考价格效应的作用。具体而言,我们假定企业可以采用广告承诺和价格承诺中的一种,其中前者承诺其在一段时间内的广告投入量恒定不变,而后者确保价格不变。两种策略不仅会影响消费者的购买决策,也会影响竞争对手的选择。在上述假定下,我们探讨了两个寡头企业在都采用广告承诺、都采用价格承诺及一个企业采用广告承诺而另一个企业采用价格承诺等三种不同情形下的最优广告和价格决策,并以此分析了三种情形下参考价格效应对最优的广告投入及定价策略的影响。最后,通过数值分析,探讨了不同情形下企业的最优策略选择。     

金融集聚、生产率增长与城乡收入差距的实证分析——基于动态空间面板模型

本文利用中国2003-2013年285个地级及以上城市的统计数据,采用动态空间面板模型实证分析了金融集聚对城市总体生产率增长及其内部城乡收入差距的影响,研究结论表明：金融集聚是促进城市总体生产率增长的重要推动力,同时也是导致城市内部城乡收入差距扩大的关键因素,这主要是因为金融集聚显著推动了城市居民人均收入水平的提高,而对农村居民人均收入水平的提升作用不显著。本文的政策含义在于,在城市金融集聚的扩散阶段还没有到来之前,政府旨在缓解城乡收入差距的金融政策可能会抑制城市总体生产率增长。     

基于Petri网的微博网络信息传播模型

微博网络中的信息传播模型是分析用户行为,找出传播路径,确定领袖人物,发现舆情热点等研究的基础。虽然多种不同角度的信息传播模型已经得到广泛研究,但缺乏对信息动态传播过程的直观描述。本文基于Petri网的结构和特征,针对微博网络信息传播过程,提出了一种简单直观的描述模型,该模型首先对微博网络的信息动态传播过程中的对象进行结构化描述。本文根据微博网络的用户结构关系,并利用Petri网的相关理论,形式化解释和定义信息传播基本对象,从而更加直接描述了微博网络中的转发、评论、回复等多种用户行为。在此基础上,本文利用Petri网能够描述信息流动问题的特征,结合颜色Petri网和时延Petri网,从Petri网系统的角度表示信息动态传播路径,并研究网络的动态性质和传播条件,使得信息传播模型更加真实地模拟信息传播情况。最后本文分析信息传播算例和新浪微博真实数据实验,验证了模型的有效性和可行性,为舆情态势分析以及用户行为的研究提供帮助和支持,同时也为其它社交网络信息传播的用户行为描述提供了新的思路。     

Does the Role of Student Factors with Adolescent Substance Use Vary by Geography?

This study assesses the association of 12th-grade student factors (e.g., grades, classroom misbehaviors) with substance use (i.e., binge drinking, cigarette smoking, marijuana) across large, medium-sized, and nonmetropolitan areas. Based on a sample of 2,189 students from the 2013 Monitoring the Future data set, logistic regression analyses showed that poor student academic and behavioral factors were associated with higher substance use after controlling for gender, race, and socioeconomic status. Interaction analyses further showed no significant differences in the influence of student factors on substance use across locales. Results suggest that prevention efforts against substance use should target student factors regardless of area of residency.     

长期执政条件下中国共产党密切联系群众动力研究

社会主义国家普遍实行的是一党长期执政。在我国当前一党执政的新时期、新形势下,中国共产党要坚定党的既定方针,带领中国人民实现中华民族的伟大复兴使命,更加需要同广大的人民群众保持密切的联系。在贯彻落实群众路线时,要切切实实地关注广大百姓的切身利益与实际问题,特别是要建立起一种能够将我党同广大人民群众密切联系起来的长效机制。     

Poly-victimization and resilience portfolios: Trends in violence research that can enhance the understanding and prevention of elder abuse

ABSTRACT

This literature review assesses the current state of knowledge about elder abuse and mistreatment, focusing on the lack of incorporation of all forms of elder victimization and the benefits of a poly-victimization framework. This review also includes existing knowledge on risk factors and calls for a greater focus on protective factors and a greater inclusion on family and community factors. Future research, prevention, and intervention would benefit from considering the true burden of elder victimization and a greater implementation of strengths-based approaches to programs.     

Association between long-term erectile dysfunction and biochemical recurrence after permanent seed I125 implant brachytherapy for prostate cancer. A longitudinal study of a single-institution

We aimed to investigate the predictive factor of erectile dysfunction (ED) in prostate cancer (PCa) patients who underwent low-dose permanent I¹²⁵ seed implant brachytherapy and to investigate if ED could represent a patient’s reported outcome measures (PROMs) of efficacy of BT and indirectly associated with biochemical recurrence free survival (BRFS). From 2000 to 2012, 176 consecutive patients with low-risk PCa underwent BT. ED was evaluated with the International Index of Erectile Function (IIEF-5). Cox regression analysis was performed to assess significant predictors of mild-to-severe ED and BRFS after BT, including covariates. The 10-year actuarial rate of ED was 66%. Subjects with severe ED had higher values of D90 (183.0 versus 177.0; p?p?p?p?=?0.20), while D90?≤?180?Gy independently predicted BCR (HR: 4.65; [95%CI: 1.25–17.34]; p?125 implant, but it is not associated with better BRFS.
