Socialization, Adaptation, Transnationalism, and the Reproductive Behavior of Sub-Saharan African Migrants in France

Background:  Migrants from Sub-Saharan Africa (SSA) move from a region with high fertility to regions with low fertility. Yet very few studies have examined the reproductive behavior of international migrants from SSA. Objective: This study examines the roles of origin and destination socialization on the fertility and fertility ideals of SSA migrants in France. The study draws on measures of assimilation to systematically examine the effects of socialization and adaptation as well as transnationalism for the effects of sustained origin ties.  Methods: Data are from the TEO (“Trajectoires et Origines”) survey conducted in France (2008/2009). Logistic regression is used to examine current fertility (the odds of having a birth in the preceding five years), and Poisson regression is used to examine cumulative fertility (children ever born) and fertility ideals (reported ideal number of children in a family). Results: Controlling for sociodemographic factors, first-generation SSA migrants have higher fertility than second-generation SSA migrants and non-immigrants. But first and second-generation SSA migrants have higher fertility ideals than non-immigrants. Among SSA migrants, first and second-generation migrants do not differ in fertility and fertility ideals when adaptation is accounted for. Most measures of adaptation are negatively associated with actual fertility and fertility ideals. Transnationalism is associated with higher fertility ideals but less so with actual fertility. Conclusion: The study finds some evidence for origin socialization, but the findings are more strongly supportive of adaptation to the host society. Origin socialization appears to have a stronger influence on fertility ideals than actual fertility

The same but different: Understanding entrepreneurial behaviour in disadvantaged communities

While entrepreneurship is widely viewed as being equally accessible in all contexts, it could be questioned if potential or nascent entrepreneurs from minority and disadvantaged communities experience entrepreneurship in a similar manner to the mainstream population. This chapter examines immigrant, people with disability, youth, gay and unemployed communities to explore how their entrepreneurial behaviour might differ from the practices of mainstream entrepreneurs. What emerges is that marginalised communities can frequently find it difficult to divorce business from social living. This can have both positive and negative connotations for an entrepreneur, plus they face additional and distinctive challenges that mainstream entrepreneurs do not experience. The chapter concludes by proposing a novel ‘funnel approach’ that policymakers might adopt when seeking to introduce initiatives targeted at these disadvantaged communities

Psychopharmacology of male rat sexual behavior: modeling human sexual dysfunctions?

Contains fulltext : 50169.pdf (publisher's version ) (Closed access)Most of our current understanding of the neurobiology, neuroanatomy and psychopharmacology of sexual behavior and ejaculatory function has been derived from preclinical studies in the rat. When a large population of male rats is tested on sexual activity during a number of successive tests, over time individual rats display a very stable sexual behavior that is either slow, normal or fast as characterized by the number of ejaculations performed. These sexual endophenotypes are postulated as rat counterparts of premature (fast rats) or retarded ejaculation (slow rats). Psychopharmacology in these endophenotypes helps to delineate the underlying mechanisms and pathology. This is illustrated by the effects of serotonergic antidepressants and serotonergic compounds on sexual and ejaculatory behavior of rats. These preclinical studies and models contribute to a better understanding of the neurobiology of ejaculation and boost the development of novel drug targets to treat ejaculatory disorders such as premature and retarded ejaculation
