Whether Professional Training Matters: Attitudinal Antecedents to the Turnover Intentions of Social Workers in Guangzhou,China

This study aims to identify whether the professional training of social workers has an effect on the attitudinal antecedents of turnover intention. This study investigated 395 trained and 353 non-trained social workers from the Integrated Family Service Centers in Guangzhou, China. It was found that professional education did not significantly alter the attitudinal antecedents to turnover intention. In both groups, a higher feeling of burnout or a lower level of organizational commitment produced a higher intention of turnover. Furthermore, the significant influences of burnout and organizational commitment were found to be respectively mediated by job satisfaction with professional association or job satisfaction with organizational environment. This study not only provides insights into the stabilization of the emerging workforce of Chinese social workers, but also poses serious questions about social work education.     

论先实施暴力后临时起意取财行为的定性

对行为人先实施暴力行为后临时起意取财的行为该如何定性?理论上主要存在着"盗窃罪"与"抢劫罪"两种观点。最高院主张被害人尚未失去知觉时定为抢劫罪,被害人失去知觉或者死亡后定为盗窃罪。因为行为人先前暴力行为与后面取财行为具有关联性,所以应把二者结合在一起作为整体来评价。先前暴力行为与后面取财行为足以填充抢劫罪构成的客观方面,由手段行为(先前暴力行为的再利用)与目的行为(取财行为)构成完整的抢劫罪的实行行为。行为性质与被害人的状态无关,被害人的状态都是行为人先前暴力行为所直接导致的结果,不能因为被害人状态不同而做出不同的定性,而应将先实施暴力后临时起意取财行为统一定性为抢劫罪。     

Demand switching criteria for multiple products: An inventory cost analysis

In this paper, we consider the problem of demand switching and show how a firm can take advantage of the risk-pooling effect to gain more profit. We examine the case of three products under various switching criteria; a model based on the heuristic approach is developed to determine the switching paths and the corresponding switching rates that yield the optimal profit. A constrained model with limited amount of the switched demand is also developed. In general, the profit increases as a result of higher profit margin or smaller demand variation and correlation. Our result indicates that the profit does not necessarily increase as the switching rate increases; in some cases the profit may even decrease as a result of demand switching. Numerical examples are also included to illustrate the derived models. The developed analytical approach may help practitioners to gain more insight in demand switching and facilitate inventory related decision-making process as well.     

University environment and entrepreneurial intention: the mediating role of the components of the theory of planned behaviour / El entorno universitario y la intención emprendedora: el papel mediador de los componentes de la teoría de la acción planificada

Entrepreneurship contributes to job creation and economic development. Thus, it is important to promote entrepreneurial initiatives; universities play a key role in this regard. The psychosocial perspective can contribute a great deal to studying the antecedents that lead a person to become an entrepreneur, with the theory of planned behaviour (TPB) being the theoretical framework used the most to predict entrepreneurial intention. Based on the data collected in Spain as part of the international GUESSS project (Global University Entrepreneurial Spirit Students’ Survey) with a sample of 9,753 students, the influence of the university environment, the entrepreneurial environment and the perceived risk of entrepreneurship on entrepreneurial intention are analysed, both directly and as mediated by the three components of the TPB (attitudes towards entrepreneurship, subjective norms and entrepreneurial self-efficacy). The results show that the university environment is the antecedent with the greatest effect on entrepreneurial intention; therefore, it is recommended that entrepreneurship be promoted through initiatives and educational programmes in the university environment.     

多语者语码转换消耗非对称性的研究

语码转换问题是多语研究的一个重要问题，语码转换消耗的非对称性在语码转换过程中也是一个重要的概念。文章通过奇偶数刊断实验来检验俄-英-中多语者在语码转换过程中是否存在非对称性转换消耗。大连理工大学30名母语为俄语，二语和三语分别是英语和汉语的国际交换生参加了本实验。实验任务是基于E—prime软件设计的奇偶数判断任务。实验结果表明：俄-英中多语者在完成奇偶数判断任务过程中，俄语和英语之间的转换消耗是呈对称性，英语和汉语之间的转换以及俄语和汉语之间的转换消耗呈非对称性。     

Modeling the Dependence of Conditional Correlations on Market Volatility

Several models have been developed to capture the dynamics of the conditional correlations between time series of financial returns and several studies have shown that the market volatility is a major determinant of the correlations. We extend some models to include explicitly the dependence of the correlations on the market volatility. The models differ by the way—linear or nonlinear, direct or indirect—in which the volatility influences the correlations. Using a wide set of models with two measures of market volatility on two datasets, we find that for some models, the empirical results support to some extent the statistical significance and the economic significance of the volatility effect on the correlations, but the presence of the volatility effect does not improve the forecasting performance of the extended models.

意图力:小说叙事的内驱动力——以明清两代小说文本为案例

文章提出区别于西方行为叙事理论的意图叙事概念。该理论概念将人的行为动力——意图纳入叙事活动的分析过程中,探讨故事形成的潜藏动因。文章发现,文本中存在作者意图、叙述者意图、人物意图三种类型,三者分别处于故事、结构、导领的不同层面,表现出由具象到抽象的不同功能,并在叙事过程中时隐时现、缺位互移、相互补充、交替转换。这些生态及功能在小说人物意图所构成的意图力结构(主意图力、同意图力、反意图力、调节意图力)关系中,表现得尤为突出。而作者意图力通过行为选择、意图力嵌入等形式表现出独有的统领、汇合功能,形成诸意图合力,不同意图力的合力是故事叙述的内驱动力。     

基于转换成本的供应链成员讨价还价能力研究

为研究影响供应链成员讨价还价能力的诸因素以及它们起作用的内在机制,建立了供应链上下游之间考虑退出威胁的讨价还价博弈模型,模型的均衡解揭示了转换成本对供应链成员策略形成机制的影响;同时通过对讨价还价能力的数学定义,结合模型分析得出供应链成员的讨价还价能力是其转换成本的减函数,并进一步指出市场份额、信息量、学习能力和忍耐度等因素影响供应链成员讨价还价能力的内在机制。
