Genetic and environmental effects on sexual excitation and sexual inhibition in men

The Sexual Inhibition and Sexual Excitation Scales (SIS/SES) measure the propensity for sexual inhibition and excitation in men. According to the theoretical model underlying the SIS/SES, sexual response and associated behavior depend on dual control mechanisms in the brain involving the balance of excitatory and inhibitory systems which impinge on sexual response. Previous research with the SIS/SES has indicated one higher-order excitatory factor and two higher-order inhibitory factors affecting sexual response. The present study analyzed the item structure and the psychometric properties of the instrument in a population based sample of Finnish male twins (N = 1,289), and, including 37 out of 45 items of the original scales, estimated the heritability of and the environmental influences on the excitatory and inhibitory mechanisms. The twin correlations and the structural equation modeling suggested modest heritability for both inhibitory mechanisms. Sexual excitation, in contrast, was not influenced by genetic effects and similarities between twins for this mechanism seemed to be caused by the common environment of the twins.     

Young Mothers and the Care System: Contextualizing Risk and Vulnerability

Although the UK has the highest levels of teenage pregnancyin Western Europe, and while adolescent mothering has receivedconsiderable recent attention from researchers, there is a paucityof research literature about the particular experiences of youngwomen who become mothers in or following local authority care.Findings from our empirical study reveal the significance ofrisk and vulnerability faced by a group of fifty-five youngmothers following their exit from care. This paper exploresthe impact of risk and vulnerability and also highlights thatalthough pregnancy may not be a planned activity, young womendemonstrate choice and rationality in their decision to becomemothers.     

Religious residue: The impact of childhood religious socialization on the religiosity of nones in France,Germany, Great Britain,and Sweden

One of the distinguishing features of religious life in Western Europe in recent decades has been the sharp increase in the proportion of people who identify as unaffiliated with any religious tradition (religious nones). Non-affiliation entails a rejection of religious belonging, not the absence of all religious belief and practice; yet the determinants of religiosity among nones have not been fully explored. Drawing on data from the 1998–2018 ISSP surveys in four West European countries (France, Germany, Great Britain, and Sweden), I test the impact of childhood religious socialization on the religiosity of unaffiliated adults by comparing lifelong nones, who were never religiously affiliated, with disaffiliates, who were raised within a religious tradition and have since exited organized religious life. Disaffiliates are consistently more religious than lifelong nones due to religious residue from childhood, with greater residue found among those who were more religiously committed as children. Religious decline among the unaffiliated over time, combined with the increasing proportion of lifelong nones and second-generation lifelong nones who lack even an inherited, minimal religious residue, suggest that secularization will gather momentum.
