The Family Contexts of Gender Development in Childhood and Adolescence

We review research on the family's role in gender development during childhood and adolescence. Our discussion highlights children's dyadic family relationship experiences with their parents and siblings; additionally, we describe ways in which the larger system of family relationships, including gendered dynamics in the marriage and the differential family experiences of sisters versus brothers may have implications for gender development. We also emphasize the significance of contextual factors—ranging from situational demands and affordances to forces emanating from the larger social ecology—in family gender socialization. We conclude that family experiences may have a more important impact on gender development than has previously been believed, and we highlight directions for future study. These include: (1) applying more complex models of parent socialization and family dynamics to the study of the family's role in gender development; (2) expanding on research directed at the socialization of sex differences to study how family dynamics are linked to individual differences in girls’ and boys’ gendered qualities and behaviors; and (3) further exploring how contextual factors exert an impact on gender socialization in the family.

Reliability in rehabilitation measurement

The article examines reliability as a key component of the psychometric properties of tests and inventories. What is reliability, types of reliability, why is reliability important, and other reliability issues are addressed in a manner that will help Work readers to better understand and apply psychometric considerations in the context of rehabilitation research. The authors contend that reliability is an essential condition for the psychometric soundness of measurement instruments that are used in rehabilitation research and practice.     

The basics of nonparametric statistics

This article introduces readers to the data analytic sub-paradigm of nonparametric statistics. The authors begin with an explanation of how and under what circumstances nonparametric statistics are used, then describe specific nonparametric techniques which are commonly used in social science research. Examples from the contemporary rehabilitation literature are provided throughout the article.     

Effect of ceasing creatine supplementation while maintaining resistance training in older men

The authors previously found that creatine (Cr) combined with 12 weeks of resistance training enhanced muscle strength and endurance and lean tissue mass (LTM) in older men. Their purpose in this study was to assess these variables with cessation of Cr combined with 12 weeks of reduced training (33% lower volume) in a subgroup of these men (n = 8, 73 years old) compared with 5 men (69 years old) who did not receive Cr. Strength (1-repetition maximum [1-RM]), endurance (maximum number of repetitions over 3 sets at 70-80% 1-RM), and LTM (dual-energy X-ray absorptiometry) were assessed before and after 12 weeks of Cr cessation combined with reduced-volume training. No changes in strength or LTM occurred. Muscle endurance was significantly reduced (7-21%; p <.05), with the rate of change similar between groups. Withdrawal from Cr had no effect on the rate of strength, endurance, and loss of lean tissue mass with 12 weeks of reduced-volume training.     

Prevalence of Problem and Pathological Gambling in Parkinson’s Disease

Pathological gambling (PG) has been identified in patients with Parkinson’s disease (PD) treated with dopamine agonists suggesting that dysregulation of brain dopaminergic activity may contribute to the development of gambling problems. The current study was undertaken to further establish the prevalence of problem and PG in patients with PD, identify any clinical correlates, and determine if psychiatric or substance use co-morbidity contributes to the increased prevalence of problem and PG. A cross-sectional survey of 140 serially recruited moderate to severe PD patients was undertaken utilizing the Canadian Problem Gambling Index, Alcohol Use Disorders Identification Test, Drug Abuse Screening Test, Beck Depression Inventory, Beck Anxiety Inventory, and Mini-Mental State Exam augmented by chart review, completed over an 8 month period. The 12 month prevalence of problem and PG in PD was 9.3% compared to 1.6% in the general population within a comparably aged sample. The increased prevalence of problem and PG in the PD group was related to dopamine agonist use and younger age, but not co-morbidity. Most subjects with problem and PG reported their gambling increased after being diagnosed with PD and starting treatment. The results suggest that brain dopaminergic activity is involved in the underlying neurobiology of problem and PG.     

Disadvantagement-related correlates of career optimism among college and university students with disabilities

This paper describes research regarding factors predicting career optimism for a group of postsecondary students with disabilities (N = 208) who were enrolled in seven colleges and universities in four states. Career optimism was defined as a student's self-confidence regarding his or her ability to choose, maintain, and advance in an appropriate career. The proposed model incorporated variables related to employment discrimination and disincentives such as perceived impact of disability on one's education and quality of life, racial/ethnic status, gender, and presence of disability benefits. Results indicated that two aspects of "disadvantagement," specifically severity of perceived impact of disability and racial/ethnic status, were significant predictors of career optimism. Implications of the findings were discussed in terms of informational interventions, curricula, development of self-advocacy and self-determination, and research topics.     

African American Digital Practices: Mobile E-Health and Residential Segregation

We ask two questions about the relationship between race, using mobile phones for e-health, and living in segregated neighborhoods: Are racial differences associated with using mobile phones for e-health, especially as they relate to African Americans? Is living in segregated neighborhoods associated with changes in mobile phone usage? We merge the National Trends Survey (HINTS) conducted by the National Cancer Institute, for information on e-health, and the US 2010 project, for the necessary measures of residential segregation. Multilevel models (Level 1 N = 2,023, Level 2 N = 183) produced two major conclusions. First, African Americans exhibit unique “digital practices” vis-à-vis e-health, such that they use e-health to share personal diagnostic information less than whites but use e-health for more practical, logistical uses than do whites. Second, residential segregation is associated with digital practices; however, considering racial differences in where people live does not reduce racial differences in e-health patterns.     

The Pyramid of Nonprofit Responsibility: The Institutionalization of Organizational Responsibility Across Sectors

Observers have noted that organizations in all sectors, whether business, nonprofit, or government, have been moving toward rationalized structures that presuppose and express empowered organizational actorhood. We draw upon neo-institutional theory in this paper to extend the argument: The arrival of organizational actorhood has precipitated a concomitant, cross-sectoral movement toward organizational social responsibility. Whereas existing research has tended to theorize the social responsibilities of businesses, we develop a pyramid conceptual schema to array the social responsibilities of nonprofits. We then document the coevolution of organizational actorhood and responsibility across both sectors with a metastudy of nearly 200 extant surveys. We chart the institutionalization of a slate of formal structures that express organizational actorhood (i.e., mission statements, vision statements, and strategic plans) and that profess and define organizational social responsibilities (i.e., core values, ethics codes, and responsibility communications). We close with implications and future directions for organizational studies and research on corporate social responsibility.     

Global Demographic Convergence? A Reconsideration of Changing Intercountry Inequality in Fertility

This research challenges the notion that the second half of the twentieth century was a period of global demographic convergence. To be sure, fertility rates fell substantially during the period, but with considerable un‐evenness. The declines in total fertility across population‐weighted countries were sufficiently disproportionate that intercountry fertility inequality, estimated using standard measures of inequality, did not begin to decline until at least 1995. Regression analysis also shows that only very recently did lagging countries begin to catch up with countries that began the transition to low fertility earlier. Contrary to findings on changing intercountry health inequality, sub‐Saharan Africa has had a greater impact on changes in fertility inequality than China. The trend in fertility inequality, where convergence is a relatively new phenomenon, stands in contrast to trends in inequality in other domains, such as income, education, and health.
