Friends’ religiosity and first sex

Researchers have established that individual religiosity influences sexual behavior and that religious support can increase consistency between personal religiosity and behavior. Researchers are less certain, however, of the effect that religious friendship networks have on sexual behavior. In addition, the effects of network characteristics such as density and one’s position in a social network have not been established. This paper uses a network subsample of the National Longitudinal Study of Adolescent Health (Add Health) to examine the effect of friends’ religiosity on the probability of first sex. We find that friends’ religiosity has an independent influence on adolescent sexual behavior that is similar in magnitude to personal religiosity. We also find evidence that friends’ religiosity has the strongest influence on the sexual behavior of adolescents who are embedded in dense social networks, in which teens’ friends are also friends with one another. These results support the hypothesis that group influences depend on the degree of embeddedness within the network and highlight the importance of studying religion as a property of groups as well as individuals.     

Frustrated Fertility: Infertility and Psychological Distress Among Women

Using a random sample of 580 Midwestern women, we test the hypothesis that women who have experienced infertility report higher psychological distress. Approximately one third of our sample reports having experienced infertility sometime in their lives, although the majority of the infertile now have biological children. Drawing hypotheses from identity and stress theories, we examine whether roles or resources condition the effects of infertility or whether its effects are limited to childless women. Infertility combined with involuntary childlessness (including biological and social) is associated with significantly greater distress. For women in this category, the risk of distress is substantial.     

Neighborhood Coethnic Immigrant Concentrations and Mexican American Children’s Early Academic Trajectories

We use data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998–1999 as well as neighborhood data from the 2000 U.S. Census to examine relationships between neighborhood Mexican immigrant concentration and reading (n = 820) and mathematics (n = 1,540) achievement among children of Mexican descent. Mixed-effects growth curves show that children living in immigrant-rich communities enter school at an achievement disadvantage relative to children in neighborhoods with fewer coethnic immigrant families. However, these disparities are driven by lower-SES families’ concentration in immigrant-heavy neighborhoods as well as these neighborhoods’ structural disadvantages. Controlling for children’s generation status and socioeconomic status, as well as neighborhood-level measures of structural disadvantage, safety, and social support, neighborhood immigrant concentration demonstrates a modest positive association with mathematics achievement among children of Mexican immigrant parents at the time of school entry. However, we do not find strong positive associations between Mexican American children’s rate of achievement growth over the elementary and middle school years and their neighborhoods’ concentration of Mexican immigrants.     

Exorcism Leads to Reenactment of Trauma in a Mauritian Woman

ABSTRACT

Childhood trauma can have a lasting effect on personality and daily functioning, leading to dissociative changes in behavior and identity. How these are interpreted and handled usually depends on local culture and beliefs. This article presents the case of a Mauritian woman with a history of childhood abuse who was exorcised to “dispel an evil spirit.” An in-depth interview exploring her experiences and meaning-making was transcribed and subjected to interpretative phenomenological analysis. This article discusses possession as a culturally accepted metaphor for incomprehensible behaviors. It shows that help-seeking pathways are determined by symptom interpretation models that are reinforced by the local environment. It also demonstrates that exorcisms are potentially retraumatizing by the enactment of painful memories and emotions during this ritual. The authors stipulate that exorcism seekers could benefit from additional clinical assessment by professionals experienced in the dissociation field.     

Improved maximum-likelihood estimation of the shape parameter in the Nakagami distribution

We develop and evaluate analytic and bootstrap bias-corrected maximum-likelihood estimators for the shape parameter in the Nakagami distribution. This distribution is widely used in a variety of disciplines, and the corresponding estimator of its scale parameter is trivially unbiased. We find that both ‘corrective’ and ‘preventive’ analytic approaches to eliminating the bias, to O(n ^?2), are equally, and extremely, effective and simple to implement. As a bonus, the sizeable reduction in bias comes with a small reduction in the mean-squared error. Overall, we prefer analytic bias corrections in the case of this estimator. This preference is based on the relative computational costs and the magnitudes of the bias reductions that can be achieved in each case. Our results are illustrated with two real-data applications, including the one which provides the first application of the Nakagami distribution to data for ocean wave heights.     

Welche privaten Veräußerungsgewinne sollten besteuert werden?

This paper analyses for various corporate tax systems whether the capital gains tax distorts investment decisions and how tax effects could eventually be neutralized. In case of the disposal of shares between private investors the capital gains tax, the corporate tax and the income tax on dividends induce a triple taxation. On the contrary, distributing cash via share repurchases instead of paying out dividends can lower the tax burden in a classical corporate tax system and a shareholder relief system respectively. These findings necessitate the differentiation between share repurchases and other realizations of stocks in order to establish a neutral capital gains tax. While the capital gains taxation on transactions between private investors has to be reduced, the taxation of share repurchases must be matched with the respective dividend taxation.
