In the examination of role dissatisfaction and decline in marital quality across the transition to parenthood, it is postulated that 1) there would be a decline in the mean level of marital quality particularly among females, and 2) that the level of perceived inequity in postpartum allocation of marital roles would moderate the effects of the transition. A background review of pertinent literature pertaining to role dissatisfaction is presented, and found to be complex. Role inequity was measured as the level of dissatisfaction with a partner's contribution to a range of different role activities postpartum. The Australian sample was comprised of 59 primiparous couples who reported levels of marital satisfaction during the last trimester of pregnancy (Time 1) and then 3 months after the birth of the baby (Time 2). Couples were recruited from a variety of sources: private physicians, childbirth classes, and public hospitals. Average marriage duration was 3.5 years. Mean female age was 23.85 years and mean male age was 26.71 years. Most had completed at least 12 years of formal education. Marital quality was measured by a 32 item Dyadic Adjustment Scale (DAS) comprised of units on dyadic satisfaction, consensus, cohesion, and affectional expression. Time 1 mean correlation of subscales was .43, and Time 2, .36. Dissatisfaction with partner's role performance was measured with an instrument of 18 items developed by Noller and Callan. Alpha coefficients were .69 and .71 for males and females respectively. Multivariate analysis of variance was used to assess marital quality scores by sex and time period and changes in marital quality due to level of postnatal role dissatisfaction by sex and time period. The Bonferronni procedure was used to control the Type 1 error rate for all analyses after the initial analysis of variance. The results revealed that the decline in marital quality reported in the literature may be a reflection of a decline in affectional expression. There was no support for the expectation that females experienced greater declines in marital quality than males, although it is possible that those experiencing greater dissatisfaction may not have provided followup data. There was support for the notion that females' levels of role dissatisfaction account for declines in marital quality; i.e., there was a decline in scores of affectional expression of women only who were also dissatisfied with a partner's role performance. When females perceived partner's performing a fair share in household tasks, marital quality increased. Future research on causation should explore the inequity model and use an objective measure of 1 or both variables. The link between role relations to the extent of change in new mothers' levels of marital quality suggests prenatal counseling on marital roles. Role inequity had no effect on male levels of decline in marital quality. Independent processes may account for these results, but there is a promising direction. 相似文献

The challenges of feminist family therapists of gender bias in family therapy training and practice models need to be considered in relation to the predominance of reentry women in masters degree programs in marriage and family therapy. This article describes a developmental training model that incorporates feminist-informed values into curriculum, program policies, instructional strategies, and program structure. The model builds on the assumption that gender-associated behaviors of both sexes have contextually determined value. Training for the appropriate application of gender-associated behaviors rather than for their inclusion or exclusion can increase female reentry student flexibility and self-confidence. 相似文献

The developmental model of adolescent antisocial behavior advanced by Patterson and colleagues (e.g., Patterson, Reid, & Dishion, 1992) appears to generalize the development of a diverse set of problem behaviors. Structural equation modeling methods were applied to 18-month longitudinal data from 523 adolescents. The problem behavior construct included substance use, antisocial behavior, academic failure, and risky sexual behavior. Families with high levels of conflict were less likely to have high levels of parent–child involvement. Such family conditions resulted in less adequate parental monitoring of adolescent behavior, making associations with deviant peers more likely. Poor parental monitoring and associations with deviant peers were strong predictors of engagement in problem behavior. These constructs accounted for 46% of the variance in problem behavior. Although association with deviant peers was the most proximal social influence on problem behavior, parental monitoring and family factors (conflict and involvement) were key parenting practices that influenced this developmental process. 相似文献

A substantial body of evidence indicates that aged-related changes in the fluidity and lipid composition of the plasma membrane contribute to cellular dysfunction in humans and other mammalian species. In the CNS, reductions in neuronal plasma membrane order (PMO) (i.e., increased plasma membrane fluidity) have been attributed to age as well as the presence of the β-amyloid peptide-25-35, known to play an important role in the neuropathology of Alzheimer's disease (AD). These PMO increases may influence neurotransmitter synthesis, receptor binding, and second messenger systems as well as signal transduction pathways. The effects of neuronal PMO on learning and memory processes have not been adequately investigated, however. Based on the hypothesis that an increase in PMO may alter a number of aspects of synaptic transmission, we investigated several neurochemical and behavioral effects of the membrane ordering agent, PF-68. In cell culture, PF-68 (nmoles/mg SDS extractable protein) reduced [3H]norepinephrine (NE) uptake into differentiated PC-12 cells as well as reduced nicotine stimulated [3H]NE release. The compound (800–2400 μg/kg, i.p., resulting in nmoles/mg SDS extractable protein in the brain) decreased step-through latencies and increased the frequencies of crossing into the unsafe side of the chamber in inhibitory avoidance training. In the Morris water maze, PF-68 increased the latencies and swim distances required to locate a hidden platform and reduced the time spent and distance swam in the previous target quadrant during transfer (probe) trials. PF-68 did not impair performance of a well-learned working memory task, the rat delayed stimulus discrimination task (DSDT), however. Studies with 14C-labeled PF-68 indicated that significant (pmoles/mg wet tissue) levels of the compound entered the brain from peripheral (i.p.) injection. No PF-68 related changes were observed in swim speeds or in visual acuity tests in water maze experiments, rotorod performance, or in tests of general locomotor activity. Furthermore, latencies to select a lever in the DSDT were not affected. These results suggest that PF-68 induced deficits in learning and memory without confounding peripheral motor, sensory, or motivational effects at the tested doses. Furthermore, none of the doses induced a conditioned taste aversion to a novel 0.1% saccharin solution indicating a lack of nausea or gastrointestinal malaise induced by the compound. The data indicate that increases in neuronal plasma membrane order may have significant effects on neurotransmitter function as well as learning and memory processes. Furthermore, compounds such as PF-68 may also offer novel tools for studying the role of neuronal PMO in mnemonic processes and changes in PMO resulting from age-related disorders such as AD. 相似文献

Role relations in the public school are viewed within the perspective of organization theory; the public school is like the prison and the public mental hospital in that neither client nor organization exercises choice concerning client participation in the organization. Based on previous studies of prisons and mental hospitals and on clues provided in a case study of a junior high school, it was predicted that counselors and principals would be less “custodial” in pupil control ideology than teachers. An instrument that measured pupil control ideology along a custodial-humanistic continuum was administered to 945 teachers, 181 principals, and 180 counselors. Results confirmed the predictions. Counselor adaptations to ideological conflict concerning pupil control in both the secondary and the elementary school are discussed. It was speculated that adaptations would function to reduce overt conflict and contribute to organizational equilibrium. 相似文献

The major purpose of this study was to investigate the effects of stimulus complexity, novelty, and affective tone on the direction of eye movements of male college students. Motion pictures were taken of S’s eye while he viewed pairs of stimuli. In no instance, in any part of the 10 sec. viewing interval, did Ss as a group fixate longer on unpleasant stimuli when they were paired with either pleasant or neutral stimuli; and pleasant stimuli consistently dominated neutral stimuli. Also, novel stimuli and complex stimuli tended to dominate their non-novel and less complex competitors. Differences in instructions were found to markedly affect the magnitude but not the direction of fixation-dominance. 相似文献
