Differentiation of Self Predicts Life Satisfaction through Marital Adjustment

Abstract

Previous studies have documented the link between differentiation of self and life satisfaction. However, the underlying mechanisms explaining these associations are yet to be tested at the dyadic level. This study examined the mediating role of marital adjustment in the association between differentiation of self and life satisfaction among 113 Turkish heterosexual married couples (N?=?226). Analyses using the Common Fate Model demonstrated that differentiation of self was associated with higher levels of marital adjustment and life satisfaction, such that marital adjustment was positively associated with life satisfaction, and in turn, marital adjustment fully mediated this association. Implications are discussed for clinicians and cross-cultural researchers who seek to promote greater life satisfaction by targeting both differentiation and marital adjustment.     

UNDERSTANDING THE SEXUALITY OF MEXICAN-BORN WOMEN AND THEIR RISK FOR HIV/AIDS

Participants in this study were 300 Mexican women of rural origin who were born and raised in villages of that country and who belong to one of three groups: married and living with their husbands in Los Angeles, California ( n = 100), married to migrant workers but living in Mexico ( n = 100), and living in Mexico with their spouses ( n = 100). Trained female professionals conducted face-to-face interviews in Spanish, in Mexico and in the United States. The purpose of this study was to identify specific sexual practices, coping strategies in sex-related situations, and fears and concerns regarding sexual intercourse. This article analyzes how these elements place Mexican ruralorigin women at risk for HIV/AIDS. It discusses the need to design intervention strategies to prevent HIV/AIDS that take into consideration the limited power of women in traditional societies and the cultural precepts that promote gender roles characterized by male dominance and female submissiveness in the sexual arena.     

Team adaptability and task cohesion as resources to the non-linear dynamics of workload and sickness absenteeism in firefighter teams

ABSTRACT

The current study builds on the non-linear Dynamic Systems (NDS) perspective to test the assumption that change in sickness absenteeism is non-linear, and that such change is due to workload, team adaptability and task cohesion. Participants were 37 firefighter teams (n = 250 individuals) from a main European capital city. The research hypotheses were tested using SPSS and the “cusp” package, in the statistical software R. The results suggest that change in sickness absenteeism behaviours over time is non-linear, with the cusp catastrophe model predicting such behaviours better than the linear and logistic models. In our model, task cohesion functions as an asymmetry factor (i.e., the independent variable that determines the strength and discrepancy between the two stable states of the dependent variable) leading to a linear change in sickness absenteeism. Interestingly, both workload and team adaptability function as bifurcation (i.e., the independent variable that determines the change between the two stable states of the order parameter) and asymmetry factors leading to non-linear and linear change in sickness absenteeism over time. This study contributes to the growing evidence that incorporating the NDS perspective enables a better understanding of action teams, namely those working in extreme environments.     

Early-life education may help bolster declarative memory in old age,especially for women

ABSTRACT

Although declarative memory declines with age, sex and education might moderate these weaknesses. We investigated effects of sex and education on nonverbal declarative (recognition) memory in 704 older adults (aged 58–98, 0–17 years of education). Items were drawings of real and made-up objects. Age negatively impacted declarative memory, though this age effect was moderated by sex and object-type: it was steeper for males than females, but only for real objects. Education was positively associated with memory, but also interacted with sex and object-type: education benefited women more than men (countering the age effects, especially for women), and remembering real more than made-up objects. The findings suggest that nonverbal memory in older adults is associated negatively with age but positively with education; both effects are modulated by sex, and by whether learning relates to preexisting or new information. The study suggests downstream benefits from education, especially for girls.     

Sex differences in human olfaction: Between evidence and enigma

The sex of individuals plays an important part in determining their olfactory abilities, with females generally being superior to males. The present review examines the way in which sex differences influence sensitivity, identification, familiarity, and recognition of odours. It also examines whether sex differences are more pronounced with some odours than others, and how sex differences are affected by the manner of testing. Two different explanations for the superiority of females over males in olfaction are evaluated.
