Cyberball: The impact of ostracism on the well-being of early adolescents

We examined the effects of ostracism in early adolescent populations using the cyberball paradigm (Williams, Cheung, & Choi, 2000). Ninety-one Swiss school students, aged 10–14 years, were randomly assigned to the ostracism (24 girls, 23 boys) or the inclusion (23 girls, 21 boys) condition and were led to believe that they were playing cyberball with two other same-sex students. In reality, they were computer-generated confederates. We assessed self-reported levels of mood before and after playing the game as well as sense of belonging, self-esteem, meaningful existence, and control after the game. Compared to nonostracized students, adolescents in the ostracism condition reported significantly lower levels of positive mood after playing the game. Furthermore, they reported a lower sense of belonging and lower levels of self-esteem, meaningful existence, and control. The present results from a non-English-speaking sample correspond well to the few earlier findings in adolescent and adult populations by suggesting that even brief periods of ostracism with unknown others can lead to a significant decrease in well-being in these age groups.

On the well-posedness of a mathematical model for lithium-ion batteries.

We discuss the well-posedness of a mathematical model that is used in the literature for the simulation of lithium-ion batteries. First, a mathematical model based on a macrohomogeneous approach is presented, following previous work. Then it is shown, from a physical and a mathematical point of view, that a boundary condition widely used in the literature is not correct. Although the errors could be just sign typos (which can be explained as carelessness in the use of d/dx versus d/dn, with n the outward unit vector) and authors using this model probably use the correct boundary condition when they solve it in order to do simulations, readers should be aware of the right choice. Therefore, the deduction of the correct boundary condition is done here, and a mathematical study of the well-posedness of the corresponding problem is presented.

Transnational parenting and the well-being of Angolan migrant parents in Europe

Studies on the transnational family highlight the emotional difficulties of migrant parents separated from their children through international migration. This article consists of a large-scale quantitative investigation into the insights of transnational family literature by examining the well-being of transnational parents compared with that of parents who live with their children in the destination country. Furthermore, through a survey of Angolan migrant parents in both the Netherlands and Portugal, we compare the contexts of two receiving country. Our study shows transnational parents are worse off than their non-transnational counterparts in terms of four measures of well-being – health, life satisfaction, happiness, and emotional well-being. Although studies on migrant well-being tend to focus exclusively on the characteristics of the receiving countries, our findings suggest that, to understand migrant parents' well-being, a transnational perspective should also consider the existence of children in the migrant sending country. Finally, comparing the same population in two countries revealed that the receiving country effects the way in which transnational parenting is associated with migrant well-being.
