Does a Self-Affirmation Intervention Reduce Stereotype Threat in Black and Hispanic High Schools?

The risk of confirming negative stereotypes about one’s social group, known as stereotype threat, depresses academic achievement among students of color and contributes to racial gaps in achievement. Some work finds that stereotype threat may be alleviated through self-affirmation exercises, translating into improved performance among students vulnerable to threat. However, this work has been conducted primarily in settings where students of color represent a relatively small segment of the student population. The current study explores whether this intervention is efficacious in schools where students of color are the majority. Through a randomized controlled trial of 886 students in three high schools (one predominantly black, one predominantly Hispanic, and one mixed race school), we administered self-affirmation exercises over the course of an academic year. We find no clear evidence that self-affirmation promoted higher standardized test scores or higher grades within the sample. The null findings highlight the complex nature of academic challenges in segregated contexts and raise important questions about the nature of stereotype thereat in such contexts. Importantly, this suggests that solely enhancing self-integrity may not be sufficient to close academic race-based gaps.     

Relationship standards and marital satisfaction in Chinese and American couples

Samples of urban community couples in Shanghai, China, and suburban U.S. couples were administered measures of relationship adjustment and personal standards regarding characteristics of couple relationships. There were few gender differences in adherence to relationship standards but many differences between Chinese and U.S. couples. Fewer cultural differences existed in degree of couple consensus on relationship standards, but both adherence to standards and couple consensus on standards were associated with partners' levels of marital adjustment. Implications of the findings for clinical assessment and intervention with distressed couples, in particular for Western therapists working with Chinese couples whose standards may conflict with goals and methods of couple therapy, are discussed.     

Cyclops Cave

Written in the post‐structural traditions of symbolic interactionism, Cyclops Cave is a biographic‐interview‐based and fact‐and‐fiction‐plotted ethnodrama of anti‐Semitism in Soviet higher education. This project is premised on the theories of the “social self”—namely, the “looking‐glass racialized self,” constructed by the dominant ethnic “supremacy,” and the theories of racial stigma as an outcome of the racialized “me” production. Showing the stigma experiences of former Soviet Jewish academics from 1970 to the 1980s, the play adds a new illuminative and self‐interpretive case of a race‐situated symbolic interaction and deconstructs the “root image” of Soviet anti‐Semitism through interpreting the informants' stigma incidents and interactional conflicts between their “selfhood” symbols.     

结合俄罗斯名画进行词汇教学经验谈

绘画作为直观的形象,能迅速、长久地保留在观众的记忆中,用外语对绘画作品中肖像和景物进行描述,可以激活学生记忆中已有的词汇,并能掌握大量新词语.画家借助绘画作品中的图形和色彩来反映生活,而语言大师则通过语言来描述生活中的各种现象.在缺少外语语言环境下,将所学语言国家的绘画艺术引入到外语实践课教学中,既可以帮助学生强化外语单词、词组的记忆,扩大外语词汇量,提高记忆词汇的效率,又可以提高学生口、笔语的实践能力,形成全面的信息储备.     

Arrow’s Axiom and Full Rationality for Fuzzy Choice Functions

A classical result for crisp choice functions shows the equivalence between Arrow axiom and the property of full rationality. In this paper we study a fuzzy form of Arrow axiom formulated in terms of the subsethood degree and of the degree of equality (of fuzzy sets). We prove that a fuzzy choice function satisfies Fuzzy Arrow Axiom if and only if it is (fuzzy) full rational. We also show that these conditions are also equivalent with weak and strong fuzzy congruence axioms WFCA and SFCA. It is studied the Arrow index, a new concept that indicates the degree to which a fuzzy choice function satisfies the Fuzzy Arrow Axiom. The author wishes to express her gratitude to the two anonymous reviewers for their valuable comments and discussions that contributed to a higher quality of the paper. Some of their comments can be found in the final version of the paper. An abstract of this paper was presented at the First Spain Italy Netherlands Meeting on Game Theory SING, Maastricht, The Netherlands, June 2005.     

Financial Strain and Smoking

Using the 1999–2005 waves of the Panel Study of Income Dynamics (PSID), this study examines the relationship between family financial strain and smoking among women and men. Family financial strain is reflected by family financial solvency and the availability of emergency funds. Results indicate that individuals residing in families with insufficient emergency funds are more likely to smoke. Moreover, the relationship between insufficient emergency funds and smoking is observed across various income and education groups. Further analysis suggests that the onset of a financial strain increases their probability of a smoking relapse among men by 8–14% points.     

Passenger and pilot risk minimization in offshore helicopter transportation

In the offshore petroleum industry, employees are transported to and from the offshore installations by helicopter, which represents a major risk. This paper analyzes how to improve transportation safety by solving the helicopter routing problem with a risk objective expressed in terms of expected number of fatalities. A mathematical model is proposed and a tabu search heuristic is applied to this problem. Three routing policies are considered: a direct routing policy, a Hamiltonian routing policy, and a general routing policy. Extensive computational experiments are conducted on instances derived from real data in order to assess and compare these policies under a travel time, a passenger risk and a combined passenger and pilot risk objective. Several management insights can be derived from this study. In particular, our results show that passenger transportation risk can be reduced by increasing travel time at the expense of pilot risk. This can be achieved through a reduction of the average number of passengers onboard by applying either a Hamiltonian or a general routing policy. Our methodology can also be used to derive an equitable distribution of risk between passengers and pilots, considering that pilots fly much more frequently than passengers.     

A Fuzzy Decision Tree for Fault Classification

In plant accident management, the control room operators are required to identify the causes of the accident, based on the different patterns of evolution of the monitored process variables thereby developing. This task is often quite challenging, given the large number of process parameters monitored and the intense emotional states under which it is performed. To aid the operators, various techniques of fault classification have been engineered. An important requirement for their practical application is the physical interpretability of the relationships among the process variables underpinning the fault classification. In this view, the present work propounds a fuzzy approach to fault classification, which relies on fuzzy if-then rules inferred from the clustering of available preclassified signal data, which are then organized in a logical and transparent decision tree structure. The advantages offered by the proposed approach are precisely that a transparent fault classification model is mined out of the signal data and that the underlying physical relationships among the process variables are easily interpretable as linguistic if-then rules that can be explicitly visualized in the decision tree structure. The approach is applied to a case study regarding the classification of simulated faults in the feedwater system of a boiling water reactor.
