How well do European child-related leave policies support the caring role of fathers?

Our chapter analyses the extent to which European countries (1) recognize the caring responsibilities of fathers toward their children and (2) value fathers' caring role. To do so, we analyze the designs of individual leave policies and reflect on them by assessing available data on leave uptake by fathers in 13 European countries. Our results show that there is great variation in child-related leave designs across Europe. Our findings, in line with previous work, underscore the importance of generous individual non-transferable leave entitlements. Moreover, our findings bring forward aspects of leave designs that are rarely discussed when considering fathers' leave uptake. Our results indicate that generous non-transferable leave rights should be paired with (a) clearly defined leave periods for fathers, (b) individual entitlement to benefits, and (c) greater scope for flexibility to increase the attractiveness of child-related leave and to strengthen fathers' position when negotiating their childcare leave.</p

Evidence that increased 5-HT release evokes region-specific effects on blood-oxygenation level-dependant functional magnetic resonance imaging response in the rat brain

This study aimed to determine the potential of in vivo functional magnetic resonance imaging (fMRI) methods as a non-invasive means of detecting effects of increased 5-HT release in brain. Changes in blood-oxygenation level-dependent (BOLD) contrast induced by administration of the 5-HT-releasing agent, fenfluramine, were measured in selected brain regions of halothane-anesthetized rats. Initial immunohistochemical measurements of the marker of neural activation, Fos, confirmed that in halothane-anesthetized rats fenfluramine (10 mg/kg i.v.) evoked cellular responses in cortical regions which were attenuated by pre-treatment with the 5-HT synthesis inhibitor p-chlorophenylalanine (300 mg/kg i.p. once daily for 2 days). Fenfluramine-induced Fos was demonstrated in numerous glutamatergic pyramidal neurons (Fos/excitatory amino acid carrier 1 (EAAC1) co-labeled), but also a small number of GABA interneurons (Fos/glutamic acid decarboxylase (GAD)(67) colabeled). Fenfluramine (10 mg/kg i.v.) evoked changes in BOLD signal intensity in a number of cortical and sub-cortical regions with the greatest effects being observed in the nucleus accumbens (-13.0%+/-2.7%), prefrontal cortex (-10.1%+/-3.2%) and motor cortex (+2.3%+/-1.0%). Pre-treatment with p-chlorophenylalanine, significantly attenuated the response to fenfluramine (10 mg/kg i.v.) in all regions with the exception of the motor cortex which showed a trend. These experiments demonstrate that increased 5-HT release evokes region-specific changes in the BOLD signal in rats, and that this effect is attenuated in almost all regions by 5-HT depletion. These findings support the use of fMRI imaging methods as a non-invasive tool to study 5-HT function in animal models, with the potential for extension to clinical studies

The Enduring Significance of Skin Tone: Linking Skin Tone, Attitudes Toward Marriage and Cohabitation, and Sexual Behavior

Past evidence has documented that attitudes toward marriage and cohabitation are related to sexual behavior in adolescence and young adulthood. This study extends prior research by longitudinally testing these associations across racial/ethnic groups and investigating whether culturally relevant variations within racial/ethnic minority groups, such as skin tone (i.e., lightness/darkness of skin color), are linked to attitudes toward marriage and cohabitation and sex. Drawing on family and public health literatures and theories, as well as burgeoning skin tone literature, it was hypothesized that more positive attitudes toward marriage and negative attitudes toward cohabitation would be associated with less risky sex, and that links differed for lighter and darker skin individuals. The sample included 6872 respondents (49.6 % female; 70.0 % White; 15.8 % African American; 3.3 % Asian; 10.9 % Hispanic) from the National Longitudinal Study of Adolescent to Adult Health. The results revealed that marital attitudes had a significantly stronger dampening effect on risky sexual behavior of lighter skin African Americans and Asians compared with their darker skin counterparts. Skin tone also directly predicted number of partners and concurrent partners among African American males and Asian females. We discuss theoretical and practical implications of these findings for adolescence and young adulthood
