Facial Expressions and Ambivalence: Looking for Conflict in All the Right Faces

The present study examined the impact of conflict over emotional expression on the nonverbal communication process between romantic partners. Fifty-four romantically involved female undergraduate students who scored within the upper or lower 30th percentile range on the Ambivalence over the Expression of Emotion Questionnaire (AEQ; King & Emmons, 1990) were recruited along with their romantic partners. The facial expressions of these women were examined during a conflict resolution task. Analyses indicated that highly ambivalent women expressed a greater number of negative facial expressions and shorter lasting positive facial expressions (measured with FACES; Kring & Sloan, 1992) than less ambivalent women. These expressions were not entirely explained by current mood, as ambivalence predicted a greater number of negative facial expressions, and a briefer display of positive facial expressions, above and beyond current levels of negative and positive affect. Furthermore, analyses indicated that the number of women's negative expressions predicted significant increases in men's dysphoria and marginal increases in men's anxiety, suggesting potential negative interactional patterns between ambivalent women and their partners.     

Race and Ethnic Self-Identification Influences on Physical and Mental Health Statuses Among Blacks

We examine if commonly used distress measures, rates of psychiatric disorders, and chronic health conditions are affected by alternate measures of race-ethnicity for African Americans and Caribbean blacks. We examined two alternative self-identification measures to investigate if their influence might differ. A study on national household probability sample of non-institutionalized African Americans (n = 3,570) and blacks from Caribbean countries, who now live in the United States (n = 1,621), was conducted between February 2001 and June 2003, using a slightly modified version of the Composite International Diagnostic Interview. The method used to measure black race and ethnicity has influence on physical and mental health outcomes. The distributions of depressive symptoms are not affected, while the distributions of DSM IV disorders and chronic health conditions vary by race and ethnic self-identifications among the African American and Caribbean black populations. There are serious implications of using alternate measures of race-ethnicity on the distribution of physical and mental health morbidity among African Americans and Caribbean blacks. The conceptualization and assessment of race-ethnicity should be carefully considered when studying mental and physical health statuses and service needs in the American black population.     

Lone Motherhood and its Educational Outcomes for Children in Vietnam

Micro-data from the 2009 Vietnam census indicate that lone mothers represent 11.0% of all women aged 15 to 49 living with at least one of their children (≤17 years old). Results from logistic regression models show that school enrollment and attainment levels are lower for children of lone mothers than for children living with two parents. This negative effect is observed for children of never married, divorced or separated, and widowed lone mothers as well as for children of women currently married to a migrant not residing in the household provided they are not head of household. This disadvantage may be explained by reduced availability of human, material, and financial resources; restricted agency of the mother; and long-term socioeconomic and demographic processes shaping family relations and migration.     

Gentrification and neo-rural populations in the Québec countryside: Representations of various actors

Rural gentrification, which is linked in particular to the migration and permanent settlement in the countryside of middle-class or affluent urbanites, is increasingly affecting contemporary rural communities. Despite the significance of this trend, the complex and many-sided phenomenon of rural gentrification has hardly been explored in scholarly research in Québec (Canada), in contrast to the abundant research that exists on this topic in the United Kingdom. Accordingly, the present article will explore different representations by and of the various actors involved vis-à-vis the emergence and polymorphous effects of the gentrification of two regional county municipalities (RCMs) in the province of Québec: Brome-Missisquoi and Arthabaska. Based on the results of qualitative interviews with the four types of actors (newcomers, long-time residents, directors of local and regional community organizations, and municipal officials), it shows the complexity of rural gentrification at various levels: 1) socio-demographically; 2) in terms of housing and economic impacts; 3) on the community and cultural levels; 4) on the physical, environmental and political levels. The findings demonstrate, among other things, the need to go further than simply portraying gentrifiers and, to this end, we have augmented our analysis with representations provided by other actors affected by rural gentrification. The article also stresses the importance of examining the overall effects of the phenomenon, both negative and positive, with a view to improving our understanding of it.

Next to Production or to Technological Clusters? The Economics and Management of R&D Location

This paper examines the relationshipbetween the location of R&D and productionactivities. By using a sample of 799 Japaneseinvestments in Europe, it distinguishes betweenaffiliates performing only R&D, bothR&D and production, and productiononly. The analysis produces two main results.First, R&D tends to locate close to productionactivities. Interestingly, however, the higherthe science-intensity of a sector, the lessimportant is the linkage with production. Thisis interpreted as the effect produced by moregeneral and transferable scientific work,compared to applied work. Second, by performinga multinomial logit analysis, we show that R&Dactivities, independent or linked toproduction, are attracted by different localfactors. Specifically, geographical proximityto the local science base is an importantfactor for locating only R&Dlaboratories compared to R&D andproduction, and production only. Firmand sector-specific characteristics also affectthe probability of setting up an independentR&D affiliate.     

Gender Differences in Job Challenge: A Matter of Task Allocation

Challenging job experiences are considered important prerequisites for management development and career success. Several researchers have suggested that women are given fewer challenging assignments than their male colleagues. To test this idea we performed two studies. The first examined possible gender differences in challenging job experiences at middle job levels. The results indicated that female employees had fewer challenging experiences in their jobs than their male counterparts. The second explored the proposition that differential assignment of challenging tasks to male and female subordinates underlies gender differences in job challenge. The results indeed suggest that supervisors' task allocation decisions are not gender‐blind and may result in women having fewer challenging job experiences than men.     

A new universal resample-stable bootstrap-based stopping criterion for PLS component construction

We develop a new robust stopping criterion for partial least squares regression (PLSR) component construction, characterized by a high level of stability. This new criterion is universal since it is suitable both for PLSR and extensions to generalized linear regression (PLSGLR). The criterion is based on a non-parametric bootstrap technique and must be computed algorithmically. It allows the testing of each successive component at a preset significance level \(\alpha \). In order to assess its performance and robustness with respect to various noise levels, we perform dataset simulations in which there is a preset and known number of components. These simulations are carried out for datasets characterized both by \(n>p\), with n the number of subjects and p the number of covariates, as well as for \(n<p\). We then use t-tests to compare the predictive performance of our approach with other common criteria. The stability property is in particular tested through re-sampling processes on a real allelotyping dataset. An important additional conclusion is that this new criterion gives globally better predictive performances than existing ones in both the PLSR and PLSGLR (logistic and poisson) frameworks.
