从关联理论看语篇语境效果的取得

阅读作为言语交际模式的一种,是作者和读者之间的动态交际过程。关联理论,从认知语用的角度,对此能做出合理的解释。本文以具体的英语阅读文本为分析对象,运用关联理论,探讨了在文本阅读中如何取得语篇语境效果。     

基金经理变更的驱动机制与市场异质性 ——基于1726只公募基金的实证检验

公募基金经理变更会影响基金产品的投资价值和风险收益预期.国内公募基金经理的变更日益频繁,但现有研究多局限在传统的委托代理框架内,偏重于对基金业绩表现与基金经理变更间一元线性关系的探讨,而对考核评价机制与市场环境特征对于上述关系的影响鲜有论及.针对普通股票型、偏股混合型、灵活配置型三类公募基金,采用2006—2019年1...     

Development and Validation of TQM Implementation Constructs

The contemporary quality management (QM) literature prescribes various quality improvement strategies. However, it lacks scientifically developed and tested constructs that represent an integrative QM philosophy. Moreover, an impact of the prescribed QM strategies on a firm's product quality has not been analyzed. Through a detailed analysis of the literature, this research identifies 12 constructs of integrated QM strategies. Using a survey of 371 manufacturing firms, the constructs are then empirically tested and validated. LISREL 7 is used for this purpose. Finally, a framework to examine the effects of integrated QM strategies on a firm's product quality is suggested. Comparisons between this and two other comprehensive scales of TQM are made.     

"逐步沉淀"与"居留决定居留"—上海市外来人口居留模式分析

文章利用2000年人口普查数据中的流动人口数据和2003年上海市第七次流动人口抽样调查数据,通过队列分析研究外来人口进入城市后居留行为的特点和动态模式,并构造外来人口居留生命表.研究发现,外来人口在城市中"不断沉淀"、累积地沉淀,居留时间越长继续长期居留的概率越高,居留时间越长继续预期居留时间越长.在此基础上,分析了外来人口长期居留与城市发展的关系,以及对城市管理的启示.     

A Bayesian-loss function-based method in assessing loss caused by ship-source oil spills in the arctic area

It is difficult to assess the risk of ship-source oil spills in Arctic waters for insurance purposes due to many unknowns and the lack of reliable data. However, maritime activities in the Arctic area continue to grow, indicating the urgent needs for the development of innovative methods to estimate loss from potential ship-source oil spills in the Arctic area. To fill this gap, we develop a hybrid Bayesian-loss function-based method to assess ship-source oil spill-related loss and implement an illustrative test on Baffin Island, Nunavut in Canada. The results confirm that our method can accurately assess loss and, subsequently, develop reliable insurance premiums for shipping activities in the Arctic area. This enables governmental and nongovernmental organizations alike to use the method as a reliable loss estimation mechanism for ship-source oil spills. Also, it is a valuable tool in designing measures for safer and more resilient Arctic shipping.     

不同决策目标下受资金约束零售商的最优采购策略研究

在提前订购和延时采购两种情景下,分别考虑最大化期望收益和最小化违约概率两种决策目标,对受资金约束零售商的最优采购量和相匹配的融资策略进行分析,结果表明,相比于以最大化期望收益为决策目标,以最小化违约概率为决策目标的零售商在提前订购中将奉行"保守"的采购量和融资策略（仅耗尽自有资金量采购而不融资）,而在延时采购中采取"激进"的采购量和融资策略（与最大化期望收益下一致）;在此基础上,对不同决策目标下受资金约束零售商的最优采购时机问题进行研究发现,在最大化期望收益下,零售商的最优采购时机由产品采购成本、市场容量均值、市场容量方差、自有资金量、银行贷款利率等多个参数共同决定,而在最小化违约概率下,零售商将始终选择延时采购。     

Southern assumptions: normalizing racialized structures at a university in the Deep South

Informed by critical race theory (CRT), we examine how African-American and white college students, at a predominantly white, structurally diverse, Southern US university, understand their cross-racial experiences. Black–white interactions are understood within the context of the so-called ‘post-racial’ environment, against the backdrop of high-profile cases of racial injustice, and within the added context of the historical legacy of slavery and Jim Crow segregation in the rural Southern United States. Our study suggests that many students, regardless of race, recognized the persistence of racial segregation, especially in nightlife and campus Greek letter organizations (GLOs). African-American students were the most vocal and troubled by this division. Unexpectedly, however, students appeared to take for granted that in the American South, racism is persistent and indestructible. Building on Bell’s (1991) notion of racial realism and Bonilla-Silva’s (2013) notion of naturalization, we expand the view that racism is inherent or related to individual preference, to place and time, with a construct we term southern assumptions. Southern assumptions are the mechanisms in which participants connect collective historical racism in the south to the race problems of today.     

Why are older adults victims of fraud? Current knowledge and prospects regarding older adults’ vulnerability to fraud

Older adults are disproportionately targeted by various kinds of fraud, which result in irreversible economic losses and great psychological distress. Over the past years, researchers have conducted systematic research on the prevalence, under-reporting, and research methods of fraud victimization in older adults. Research paradigms regarding fraud victimization among older adults have mainly included cognitive, emotion regulation and motivation, and comprehensive paradigms. Factors shown to influence fraud victimization among older adults include cognitive decline, emotional regulation and motivational changes, their overly trusting nature, psychological vulnerability, social isolation, risk-taking, and a lack of knowledge and information regarding fraud prevention. Based on a review of the literature, future research can benefit from constructing a comprehensive fraud victimization theory, improving research methods, extending existing research, exploring physiological mechanisms of elderly fraud, and strengthening prevention and intervention efforts.     

论阿伦特对现代性的政治哲学反思

在阿伦特看来,现代性中孕育着种种危机,比如个体的原子化、公共空间的消失等。而这些危机就是现代极权政治兴起的重要社会条件,而矫治危机的办法之一,就是个体以积极的姿态介入公共生活,尤其是政治生活中。
