“无厘头”的影片观看及审美效果的形成

对于“无厘头”影片作为一种文化现象的研究很多,但却少有涉及穿插“无厘头”桥段如何对影片造成影响以及如何形成最终审美效果等观影过程的探讨。自电影符号学之后开始出现影片细读和精神分析取向,而德勒兹哲学则试图对传统的精神分析模式进行改造,将电影的观看视为强度流的物质实践活动。基于此,“无厘头”电影的观看可以看作镜头流与观看的观众身体流的汇合。把镜头流视为叙述文本,通过内在于文本的叙述逻辑（符号意指链的断裂／重组）之间张力的解读,在大量的镜头分析中总结出影片穿插“无厘头”桥段、形成审美效果的规律,并在三阶段的区分中分析张力强度与剧情认同程度关系所造成的影片整体审美效果变动。     

基于SAO语义分析的潜在技术合作伙伴识别

将SAO语义结构信息引入技术伙伴识别选择过程中,构建基于SAO语义分析的技术合作伙伴识别体系,通过对企业进行技术愿景分析、企业知识库分析确定技术合作网络,对网络内企业重点子技术领域进行相似度分析,从而识别企业潜在的技术合作伙伴,并制定针对性的合作方案。以染敏太阳能电池为案例开展实证研究,验证了该方法体系的可行性。

Organizational identification as a mediator for the effects of psychological contract breaches on organizational citizenship behavior: Insights from the perspective of ethnic minority employees

This study examines the contribution of the psychological contract (PC) framework to the understanding of ethnic minority employees’ employment relationships. First, it tests the generalizability of PC types (transactional, relational, and balanced) observed in the general population to ethnic minority employees. Then, to further address the unique needs and motivators of minority employees, this study considers diversity-related PCs. It adopts social exchange theory to explain how transactional, relational, balanced, and diversity-related PC breaches predict organizational citizenship behavior (OCB). Moreover, it draws insights from social identity theory and examines the mediating role of organizational identification in the relationship between types of PC breach and OCB. Data from 361 Turkish employees working as ethnic minorities in Belgium indicate that relational and diversity-related PC breaches predict OCB partially via organizational identification while transactional and balanced PC breaches directly affect OCB.     

Understanding the Ecological Validity of Relying Practice as a Basis for Risk Identification

Understanding the reliability of hazardous organizations and their protective systems is central to understanding the risk they produce. Work on “high reliability organization” has done much to illuminate the conditions in which social organization becomes reliable in highly demanding conditions. But risk depends just as much on how relying entities do their relying as it does on the reliability of the entities they rely on. Patterns of relying are often opaque in sociotechnical systems, and processes of relying and being relied on are mutually influencing in complex ways, so the relationship between relying and risk may not be at all obvious. This study was an attempt to study relying as a social practice, in particular analyzing how it had ecological validity in a social organization—how practice was responsive to the conditions in which it took place. This involved observational fieldwork and inductive, qualitative analysis on an offshore oil and gas production platform that was nearing the end of its design life and undergoing refurbishment. The analysis produced four main categories of ecological validity: responsiveness to formal organization, responsiveness to situational contingency, responsiveness to information asymmetry, and responsiveness to sociomateriality. This ecological validity of relying practice should be a primary focus of risk identification, assessing how relying can become mismatched to reliability in certain ways, both when relying practice is responsive to circumstances and when it is not.     

Dynamic inference for non-Markov transition probabilities under random right censoring

The main contribution of this article is the verification of weak convergence of a general non-Markov (NM) state transition probability estimator by Titman, which has not yet been done for any other general NM estimator. A similar theorem is shown for the bootstrap, yielding resampling-based inference methods for statistical functionals. Formulas of the involved covariance functions are presented in detail. Particular applications include the conditional expected length of stay in a specific state, given occupation of another state in the past, and the construction of time-simultaneous confidence bands for the transition probabilities. The expected lengths of stay in a two-sample liver cirrhosis dataset are compared and confidence intervals for their difference are constructed. With borderline significance and in comparison to the placebo group, the treatment group has an elevated expected length of stay in the healthy state given an earlier disease state occupation. In contrast, the Aalen-Johansen (AJ) estimator-based confidence interval, which relies on a Markov assumption, leads to a drastically different conclusion. Also, graphical illustrations of confidence bands for the transition probabilities demonstrate the biasedness of the AJ estimator in this data example. The reliability of these results is assessed in a simulation study.     

Partial Identification of Economic Mobility: With an Application to the United States

Abstract

The economic mobility of individuals and households is of fundamental interest. While many measures of economic mobility exist, reliance on transition matrices remains pervasive due to simplicity and ease of interpretation. However, estimation of transition matrices is complicated by the well-acknowledged problem of measurement error in self-reported and even administrative data. Existing methods of addressing measurement error are complex, rely on numerous strong assumptions, and often require data from more than two periods. In this article, we investigate what can be learned about economic mobility as measured via transition matrices while formally accounting for measurement error in a reasonably transparent manner. To do so, we develop a nonparametric partial identification approach to bound transition probabilities under various assumptions on the measurement error and mobility processes. This approach is applied to panel data from the United States to explore short-run mobility before and after the Great Recession.
