We used data from two waves of the National Survey of Families and Household to investigate changes in mothering behavior associated with remarriage or cohabitation by single mothers. We considered three dimensions of mothering: (a) time and supervision, (b) harsh discipline, and (c) relationship quality. Mothers and children agreed that mothers who remained in new partnerships used harsh discipline less frequently than mothers who remained single or whose new partnership had ended by the second interview. Mothers reported less supervision if they had experienced a disrupted partnership, whereas children reported less supervision if their mothers remained in a new partnership at the second interview. Children but not mothers reported better relationships with mothers in partnerships at the second interview, compared with children whose mothers remained single or whose new partnership had ended. Only a small part of the differences in harsh discipline, and none of the other observed differences, could be explained by maternal or family characteristics or by mothering behavior and relationships in the first interview. Although cohabiting partnerships were more likely to end than were marriages, we found no differences in effects of cohabiting or marital partnerships, net of their status at the second interview.  相似文献

This article focuses on the use of independent money management by a small number of cohabitants living in New Zealand. This style of money management seems to be popular with cohabitants and is likely to become increasingly significant as the number of couples who cohabit continues to grow in Western countries such as New Zealand. Yet it has received sparse attention within the literature on domestic monies. This literature has noted that money management practices operate either to diminish or to exacerbate inequalities between women and men, most noticeably in the realm of decision‐making and personal spending money. Independent money management is pursued in order to achieve equality and autonomy, thereby overcoming some of the difficulties identified in other forms of money management. However, it is argued that equality and autonomy exist in tension with each other. In certain relational settings, adherence to the goal of autonomy leads to the emergence of inequalities and the continued exercise of power within heterosexual relationships.  相似文献

Foucault's conceptualization of power relations provides a theoretical framework for cross-cultural psychotherapy reimbursed by a managed health insurance plan. Utilizing extensive case material from psychotherapy with a White therapist and an African American adolescent, the paper discusses how clinical social workers can operate within, but not be completely of dominant power structures. Applications are also made to supervision, education, and administration.  相似文献

Couple childbearing plans and births in Sweden   总被引:1,自引:0,他引:1  
We use data from a nationally representative sample of Swedish couples to estimate effects of partners’ childbearing plans on the rate of subsequent childbearing. Only 11% of the couples in this sample expressed plans in opposite directions (plan to have a child versus not to have a child), but 24% had differing levels of certainty about their plans. Of the couples in which both partners said they definitely planned to have another child, 44% had a child within two years. If neither partner planned to have another child, less than 2% of couples had a birth. The figure was 6% if the partners had opposing childbearing plans. Thus, both men and women exerted veto power over further childbearing. Disagreements were equally likely to be resolved in favor of the woman as of the man, and effects of partners’ plans on the birth hazard did not depend on the couple’s gender arrangements, family ideologies, or marital status. We discuss these results in the context of Sweden’s public support for gender equality and for childrearing, its pervasive contraceptive regime, and its high rates of cohabitation. We also argue for the collection of data from partners in future family and fertility surveys.  相似文献

The effectiveness of occupational health and safety management systems (OHSMS) can be understood through analysis of surveys such as the experiences of exposure to occupational hazards by Australian nursing occupations. How effectively OHSMS are implemented in the Australian health industry is unclear as few studies describe current hazard exposure patterns or the impact of OHSMS in the Australian health industry. This paper concludes from the analysis of an Exposure Survey of Australian nursing occupations that nursing occupations perceive themselves to be "at risk" of injury and/or management of OHS risk in work duties is affected by the patterns of hazard exposure, occupation group as well as employee attributes, perceptions, patterns and situations of work. The results highlight the top-rated hazards and imply that the perceptions of hazards in the workplace are different to actual risk experience (e.g. injury patterns). There is an unacceptable level of exposure to diverse hazards in Australian nursing occupations workplaces in regard to regulatory and performance obligations. Stronger strategies to achieve more effective risk treatment, integrate with hospital accreditation and quality programs are discussed to benefit system performance and the welfare of those in nursing occupations.  相似文献

Adolescent sexual maturation is staged using Tanner criteria assessed by clinicians, parents, or adolescents. The physiology of sexual maturation is driven by gonadal hormones. We investigate Tanner stage progression as a function of increasing gonadal hormone concentration and compare performances of different raters. Fifty‐six boys (mean age, 12.7 ± 1.3 years) and 52 girls (mean age, 12.0 ± 1.6 years) were seen at baseline, 6 and 12 months. Estradiol and testosterone concentrations were determined from three morning serum samples and Tanner stage by three different raters (clinician, parent, and adolescent). Results confirm that Tanner criteria reflect gonadal hormone concentrations, and clinician rating provides optimal assessment. Detailed insight about the strengths and limitations of different raters is provided, augmenting the scientific understanding of pubertal development.  相似文献

Prediction of body fat in older adults by time spent in sedentary behavior   总被引:1,自引:0,他引:1  
The purpose of the study was to determine the relationship between sedentary behavior (SB), physical activity (PA), and body fat (total, abdominal) or body size (body-mass index [BMI], waist circumference [WC]) in community-dwelling adults 50 yr old and over. This study included 232 ambulatory adults (50-87 yr, 37.4% ± 9.6% body fat [BF]). Average daily time spent in SB (<100 counts/min) and light (100-759 counts/min), lifestyle-moderate (760-1,951 counts/min), walking-moderate (1,952-5,724 cts/min), and vigorous-intensity (≥ 5,725 counts/min) PA were determined by accelerometer and corrected for wear time. BF was measured with dual-energy X-ray absorptiometry. SB was positively related to measures of BF. Measures of SB, PA, and gender accounted for 55.6% of the variance in total BF, 32.4% of the variance in abdominal fat, and 28.0% of the variance in WC. SB, PA, and age accounted for 27.1% of the variance in BMI. Time spent in SB should be considered when designing obesity interventions for adults 50 yr old and over.  相似文献

In a socially diverse sample of 206 infant–mother pairs, we investigated predictors of infants’ attachment security at 15 months, with a particular emphasis on mothers’ tendency to comment appropriately or in a non‐attuned manner on their 8‐month‐olds’ internal states (so‐called mind‐mindedness). Multinomial logistic regression analyses showed that higher scores for appropriate mind‐related comments and lower scores for non‐attuned mind‐related comments distinguished secure‐group mothers from their counterparts in the insecure‐avoidant, insecure‐resistant, and insecure‐disorganized groups. Higher scores for appropriate mind‐related comments and lower scores for non‐attuned mind‐related comments also independently predicted dichotomous organized/disorganized attachment. General maternal sensitivity predicted neither attachment security nor organization, although sensitivity was found to relate to dichotomous secure/insecure attachment specifically in the context of low socioeconomic status. The findings highlight how appropriate and non‐attuned mind‐related comments make independent contributions to attachment and suggest that mind‐mindedness is best characterized as a multidimensional construct.  相似文献

Average bioequivalence (ABE) has been the regulatory standard for bioequivalence (BE) since the 1990s. BE studies are commonly two-period crossovers, but may also use replicated designs. The replicated crossover will provide greater power for the ABE assessment. FDA has recommended that ABE analysis of replicated crossovers use a model which includes terms for separate within- and between-subject components for each formulation and which allows for a subject x formulation interaction component. Our simulation study compares the performance of four alternative mixed effects models: the FDA model, a three variance component model proposed by Ekbohm and Melander (EM), a random intercepts and slopes model (RIS) proposed by Patterson and Jones, and a simple model that contains only two variance components. The simple model fails (when not 'true') to provide adequate coverage and it accepts the hypothesis of equivalence too often. FDA and EM models are frequently indistinguishable and often provide the best performance with respect to coverage and probability of concluding BE. The RIS model concludes equivalence too often when both the within- and between-subject variance components differ between formulations. The FDA analysis model is recommended because it provides the most detail regarding components of variability and has a slight advantage over the EM model in confidence interval length.  相似文献
