Cross Validation of the Gambling Problem Severity Subscale of the Canadian Adolescent Gambling Index (CAGI/GPSS) on a Sample of Ontario High School Students

This paper reports on the cross validation of the Gambling Problem Severity Subscale of the Canadian Adolescent Gambling Index (CAGI/GPSS). The CAGI/GPSS was included in a large school based drug use and health survey conducted in 2015. Data from students in grades 9–12 (ages 13–20 years) derived from the (N = 3369 students). The CAGI/GPSS produced an alpha of 0.789. A principle component analysis revealed two eigenvalues greater than one. An oblique rotation revealed these components to represent consequences and over involvement. The CAGI/GPSS indicated that 1% of the students fell into the “red” category indicating a severe problem and an additional 3.3% scored in the “yellow” category indicating low to moderate problems. The CAGI/GPSS was shown to be significantly correlated with gambling frequency (r = 0.36), largest expenditure (r = 0.37), sex (more likely to be male) (r = ?0.19), lower school marks (r = ?0.07), hazardous drinking, (r = 0.16), problem video game play (r = 0.16), as well as substance abuse. The CAGI/GPSS was cross validated using a shorted version of the short SOGS, r = 0.48. In addition the CAGI/GPSS and short SOGS produced very similar patterns of correlations results. The results support the validity and reliability of the CAGI/GPSS as a measure of gambling problems among adolescents.     

基因技术、自然与社会失序 ——“敬畏生命伦理”视野下的《羚羊与秧鸡》

《羚羊与秧鸡》虚构了一个晚期资本主义极权政治、商业文化与技术垄断相结合的恶托邦后人类社会,精细地再现了多元的人性、技术垄断与个人意志的碰撞、后人类社会的社会失序与人为的自然秩序失衡、精神贫困与技术风险。通过毁灭性基因工程所触发的末世景象,小说艺术地再现了人类对现代技术的深刻欲望与恐惧,折射出由人性的恶、大公司的资本主义利润追逐与技治主义、个体与社会的精神性之扭曲、缺乏对生命的敬畏等多种因素交互作用而形成的风险社会。文章通过小说家对人类未来的思考,探讨了“技术伦理的发展”滞后于技术自身发展的问题。现代技术在具体的政治、文化、经济体制中运行,它的存在本应是服务人类而非辖制人类。借助于“敬畏生命”伦理,启迪读者正确把握人类在与社会、自然关系中的自我定位,以比较完善的生命伦理原则来矫正后人类社会的缺陷,建构“以自然为中心”“以生命为中心”“诗意地栖息”的人类社会。

Spatial Differentiation and Driving Forces of Migrants’ Socio-Economic Integration in Urban China: Evidence from CMDS

Migrants’ socio-economic integration is a major theme in migration research, which can provide economic and cultural benefits. And it will contribute to social stability. The investigation from the spatial perspective should also be considered. This paper aims to examine the spatial differentiation of the socio-economic integration of migrants and identify its driving forces to provide crucial evidence and policy recommendations to urban policymakers and further improve migrants’ socio-economic integration. Based on the latest China Migrants Dynamic Survey, this paper uses global Moran’s I index, hot spot analysis and GWR model to explore spatial differentiation and driving forces of the socio-economic integration of 155,789 migrants in 291 cities at prefecture level and above in China. The results show that: (1) The socio-economic integration of migrants consists of five dimensions, which are economic integration, cultural integration, social security, social relation and psychological integration. Among them, psychological integration is the highest (73.16) and economic integration is the lowest (13.38). (2) The socio-economic integration of migrants is mainly influenced by their own characteristics instead of the destination characteristics. Four factors (age, education, length of stay and population growth rate) positively affect migrants’ socio-economic integration, while three factors (inter-provincial mobility, proportion of tertiary industry in GDP, and ratio of teacher to student in middle school) negatively impact the socio-economic integration of migrants. (3) The socio-economic integration of migrants shows the distribution pattern of agglomeration. And the integration also presents a significant spatial heterogeneity. The driving forces of the socio-economic integration exhibit various zonal spatial differentiation patterns, including “E–W”, “SE–NW”, “NE–SW”, and “S–N”. Finally, some useful recommendations are given for improving migrants’ socio-economic integration.

     

互动视角下构式压制和承继的合力机制——基于羡余否定构式“好不X”封闭语料库的研究

构式与其组构成分间的互动关系一直是构式语法关注的核心问题之一。Goldberg在构式语法理论框架中提出了动词与构式的双向互动观，但在实际论述中却过于强调构式对动词的单向压制，降低了动词义对构式生成的贡献，忽略了对构式组构成分的系统研究。以构式与其组构成分间的互动关系为视点，从构式压制与承继的辩证关系出发，进一步阐释图示构式生成是构式与组构成分在互动压制和多重承继合力作用下的结果。同时，基于封闭语料库穷尽分析汉语羡余否定构式"好不X"的特征，结果表明：构式压制与词汇压制是双向互动的；图示构式特征的形成取决于构式对其组构成分的多重动态承继；图示构式基于互动压制承继合力机制的形成。     

反讽失效与主题表达落空——《一步之遥》相互矛盾的目的与效果

对《一步之遥》过度阐释的褒扬与不知所云的批评并存的根源在于:电影试图通过后现代主义的叙事策略来实现对历史与现实社会的深刻批判，却没能为深刻的反思和批判找到平面化的叙述表达，实现雅俗共赏的叙事效果。反而让情节线上旁逸出来的事件割裂了叙事的完整性，人物在事件中的行为失却了性格决定的心理动机支撑，影像的原意与反讽喻义交织共生导致反讽失效。即在解构之后，《一步之遥》没能建构起其预期的批判性意义体系，主题表达落空。同时解构与重构之间难以剥离、区分和确定的繁复意义及其体验瓦解了电影观众的观影快感。     

基于HHM-RFRM的船舶航行风险评估方法研究

船舶航行风险是由各种风险因素交互作用产生。综合 HHM-RFRM 理论，构建船舶航行多维风险情景危险度测度模型，以风险因素耦合视角探讨船舶航行风险管理问题。在船舶航行多维风险情景危险度测度模型中结合贝叶斯定理，对船舶航行风险情景进行了定性与定量化过滤、评级。最后以大连港某从事商务活动的货船为例，验证了所提出方法的可行性。传统的风险评估方法只能评估单个风险因素对系统的影响，此评估方法克服了这一局限性，为船舶航行风险管理提供新的视角。     

集体行动视角下的制度逻辑演化机制研究

通过对我国专车服务市场制度变革过程的纵向案例研究，探讨了组织场域中的集体行动如何推动制度逻辑演化的内在机制问题。研究发现：制度逻辑的演化过程主要经历了分离、冲突和共存三种状态，不同的制度逻辑的演化是由行动主体能动性策略和资源利用所构建的集体行动模式差异性驱动的。制度变革机会的涌现促使场域中的行动主体采用协调性的集体行动模式，促成了新制度逻辑的生成，并导致了新、旧两种制度逻辑的分离；在制度变革机会变得模糊的场域中，行动主体非协调的集体行动促使新、旧两种制度逻辑之间的激烈冲突；而在制度变革机会沉没的情境下，行动主体再协调性的集体行动最终促成了新、旧两种制度逻辑的共存。研究结论对我国当前复杂制度环境下新兴业态的发展以及传统业态的协同治理提供了重要的借鉴和启示。     

Relation between the skew-rank of an oriented graph and the independence number of its underlying graph

An oriented graph \(G^\sigma \) is a digraph without loops or multiple arcs whose underlying graph is G. Let \(S\left( G^\sigma \right) \) be the skew-adjacency matrix of \(G^\sigma \) and \(\alpha (G)\) be the independence number of G. The rank of \(S(G^\sigma )\) is called the skew-rank of \(G^\sigma \), denoted by \(sr(G^\sigma )\). Wong et al. (Eur J Comb 54:76–86, 2016) studied the relationship between the skew-rank of an oriented graph and the rank of its underlying graph. In this paper, the correlation involving the skew-rank, the independence number, and some other parameters are considered. First we show that \(sr(G^\sigma )+2\alpha (G)\geqslant 2|V_G|-2d(G)\), where \(|V_G|\) is the order of G and d(G) is the dimension of cycle space of G. We also obtain sharp lower bounds for \(sr(G^\sigma )+\alpha (G),\, sr(G^\sigma )-\alpha (G)\), \(sr(G^\sigma )/\alpha (G)\) and characterize all corresponding extremal graphs.     

双元领导对亲社会性沉默的影响

 亲社会性沉默可能是唯一能产生积极影响的沉默行为，当前对亲社会性沉默的前因研究尚显不足。激烈的竞争环境要求领导者具备双元能力，关于双元领导效应的研究主要集中在创新领域，而领导者结构化了员工的工作环境，将会影响员工的认知和行为，并且沉默行为主要由领导者造成。因此，探讨双元领导对亲社会性沉默的影响具有重要的理论和实践意义。        整合不确定管理理论和权力社会距离理论，以210名企业员工为样本，运用Spss 22和Mplus 7进行层次回归分析和验证性因子分析，探讨权力视角下双元领导对员工亲社会性沉默的影响，检验个人权力感知的中介作用以及中庸思维和权力距离导向的调节作用，揭示双元领导影响员工亲社会性沉默的内在机制。        研究结果表明，①双元领导正向影响员工亲社会性沉默，个人权力感知负向影响员工亲社会性沉默；②个人权力感知在双元领导与亲社会性沉默间起完全中介作用；③中庸思维负向调节双元领导与个人权力感知的关系；④权力距离导向正向调节个人权力感知与亲社会性沉默的关系。        实证检验双元领导对亲社会性沉默的影响，拓展了沉默行为相关研究；选取权力视角的双元领导为切入点，丰富了双元领导影响的研究；探讨亲社会性沉默的中介机制，从权力距离导向视角验证了个人权力感知对沉默行为的影响；通过引入中庸思维和权力距离导向作为调节变量，有效回应了管理学本土化研究倡议。研究结论对组织管理实践具有一定的指导意义。
