Cohabiting partners’ economic circumstances and marriage

Past studies of the transition to marriage generally have relied on information about only one individual or have attempted to measure characteristics of potential spouses indirectly. Drawing on data from the two waves of the National Survey of Families and Households (NSFH), we examine the effects of economic circumstances of both partners in cohabiting unions on the transition to marriage. Focusing on both partners in a relationship affords a more direct test of the relative importance of men’s versus women s economic circumstances. Our findings suggest that only the male partner’s economic resources affect the transition to marriage, with positive economic situations accelerating marriage and deterring separation. Our results imply that despite trends toward egalitarian gender-role attitudes and increasing income provision among women, cohabiting men s economic circumstances carry far more weight than women’s in marriage formation.     

Sexual expression: its emotional context in heterosexual, gay, and lesbian couples

Much of what is known about emotions and sexuality explores the relationship enhancing qualities of positive affect. This research extends the current literature by focusing on the association between negative feelings and sexual thoughts and experiences in the context of close relationships, controlling for the effect of positive feelings. Specifically, the unique effects of daily negative feelings toward one's partner in general and specific negative feelings (i.e., anger, anxiety, and sadness) on the sexual experience of heterosexual, gay male, and lesbian relationships were explored. Participants completed an initial questionnaire followed by daily diary measures for 14 consecutive days. Positive feelings were positively associated with sexual variables as expected. Negative feelings were associated with increases in sexual behaviors for heterosexual men and women and gay men, but not lesbian women. Sadness showed a unique positive association with arousal, lust, wanted sexual behavior, and sexual behavior for heterosexual men and women and gay men, but not lesbian women. Neither anger nor anxiety was uniquely associated with the sexual experience for heterosexual or same-sex couples.     

The Relationship Between Maternal Education and Children's Academic Outcomes: A Theoretical Framework

The importance of maternal education for children's academic outcomes is widely recognized, and yet the multiple potential mechanisms that explain this relationship are underexplored. The authors integrate theories of human, cultural, and social capital with 2 developmental psychology theories—bioecological theory and developmental niche theory—to draw attention to how maternal education may influence children's academic outcomes through a range of parenting mechanisms, some of which have been largely neglected in research. This framework provides a more complete picture of how maternal education shapes proximal and distal influences on children's academic outcomes and the ways in which these mechanisms interact and reinforce one another across time and context. The implications of this framework for future family research are then discussed.     

The effect of artificial light on bat richness and nocturnal soundscapes along an urbanization gradient in an arid landscape of central Peru

Urbanization usually reduces bat richness; however, the presence of green areas within cities and peripheral rural areas in arid ecosystems may provide microhabitats for some species. Light pollution is a major feature of urbanization, but its impact on bat behavior appears to be species-specific and previous studies have documented contrasting responses. Moreover, the effect of urbanization on bat species has been poorly studied in arid regions. We assessed the effect of artificial night light intensity (as a proxy of urbanization) on both bat occupancy and the acoustic space used (ASU) in an urbanization gradient in Peruvian central coast, based on passive acoustic recorders. We collected 26,169 recordings from 19 sites which resulted in 579 independent detections of 15 bat species. Variation in both ASU and species richness was best explained by artificial night light intensity. Species-specific effects of the artificial night light intensity based on a multi-species occupancy modeling showed that this covariate had a negative effect on occupancy for most of the bat species (12 species). ASU and both observed and posterior bat species richness were positively correlated, suggesting that ASU can be used as a proxy of bat richness. This study provides evidence that both bat richness and occupancy decrease with artificial light intensity; nevertheless, eight species used urban areas, similar to results found in other cities around the world.
