Purpose: Prenatal exercise is a health behavior that is receiving growing attention amid concern that women in Western societies are gaining excess weight during pregnancy and contributing to future obesity in both the mother and child. In this article, we draw on insights from the fields of social epidemiology and social theory of the body to examine existing prenatal exercise interventions and to propose a multidimensional framework intended to guide future theorizing and intervention design. Method: A scoping review of existing prenatal exercise programs and interventions focused on controlling gestational weight gain was conducted. Articles published prior to January 2017 were obtained from PubMed and CINAHL, and relevant articles were identified (n = 62) using specified inclusion and exclusion criteria. Identified articles were further analyzed to classify the level(s) of the socioecological model targeted in the intervention or program. Results: The majority of existing interventions target intrapersonal factors during pregnancy and do not attend to the role that cumulative exposure of social and structural disadvantage over the lifetime—not just during the prenatal period—plays in shaping health outcomes. In response, a multidimensional framework is proposed that includes key concepts that facilitate a life-course perspective, as well as attention to the integration of biological and social factors as they relate to health and health-related behaviors. Conclusion: Efforts to promote prenatal exercise and to improve maternal and infant health should attend to how systemic inequality impacts women’s health. 相似文献

In 1866, military drill and instruction became part of the curriculum of Maryland Agricultural College as a result of the passage of the Morrill Act of 1862, a law setting the terms for the establishment of agricultural colleges across the USA. The introduction of military instruction meant a direct inclusion of physically active coursework that preceded the widespread emergence of organized physical education courses in American educational institutions. However, this was not the first time physical activity was used and discussed at the college: previously, the uses of physical activity at the college wholly entailed outdoor agricultural practice in which students applied pedagogical training about agricultural techniques in the field. In this paper, we examine early Maryland Agricultural College printed discourse from 1859 to 1886, studying how the college shifted focus from idealizing the Republican male citizen as a physically active farmer or ‘cultivator of the soil’ in the years preceding the American Civil War to a physically active ‘citizen-soldier’ in response to the social and political effects of the conflict. Our analysis sheds light on the historical place of such physical activity coursework within the larger historical narrative of American physical education's emergence, and also provides useful historical context for critically viewing linkages between physical culture, nationalism, agricultural education and the military in contemporary physical education. 相似文献

Chelladurai developed the Multidimensional Model of Leadership, which was designed to be situation-specific to examine leadership behaviour and effectiveness in sporting contexts. Applying Chelladurai's concept to the Singapore sporting context, this study aimed to assess the impact of congruence between perceived and preferred leadership behaviours on satisfaction with leadership among college student-athletes in Singapore. Data were collected from 185 college student-athletes enrolled in the five local tertiary institutes. The questionnaire utilized in this study consisted of the perception and preference versions of the Revised Leadership Scale for Sports and seven items measuring satisfaction with coaching leadership. Confirmatory factor analysis and a series of hierarchical multiple regression procedures were carried out to test the psychometric properties of the leadership scale and the hypothesized relationship between congruence levels and satisfaction. Results revealed congruence of perceived and preferred behaviour in social support was a significant indicator of athletes' satisfaction. Possible implications from the findings were discussed in an effort to better understand coaching effectiveness in Singapore. 相似文献

Peer review of teaching is recognized increasingly as one strategy for academic development even though historically peer review of teaching is often unsupported by policy, action and culture in many Australian universities. Higher education leaders report that academics generally do not engage with peer review of teaching in a systematic or constructive manner, and this paper advances and analyses a conceptual model to highlight conditions and strategies necessary for the implementation of sustainable peer review in higher education institutions. The model highlights leadership, development and implementation, which are critical to the success and formation of a culture of peer review of teaching. The work arises from collaborative research funded by the Office for Learning and Teaching to foster and advance a culture of peer review of teaching across several universities in Australia. 相似文献

Academic libraries are often tasked with open access (OA) policy implementation. Many academic libraries have developed robust workflows that utilize custom-built management tools and receive support from a number of library staff. While such workflows certainly streamline the process, their development and management require significant resources. As the number of smaller institutions with OA policies increases, there is a need for solutions that are efficient, flexible, and can be accomplished with minimal resources. Staff at Rice University's Fondren Library developed a simple workflow that populates the institutional repository, freeing up time for OA policy outreach and awareness activities. 相似文献

We discuss the ability to perform fluorescent immunocytochemistry, following cell fixation, using a microfluidic array of primary, nonadherent, single CD34+ stem cells. The technique requires small cell samples and proceeds with no cell loss, making it well-suited to monitoring these rare patient-derived cells. The chip allows us to correlate live cell dynamics across arrays of individual cells with post-translational modifications of intracellular proteins, following their exposure to drug treatments. Results also show that due to the microfluidic environment, the time scale of cell fixation was significantly reduced compared to conventional methods, leading to greater confidence in the status of the protein modifications studied. 相似文献

OBJECTIVE: This article focuses on caseworkers' assessments of risk of maltreatment recurrence among families in contact with social services. Specifically, the article has two primary goals: (1) to examine the association between caseworkers' risk assessments and demographic, child, parent and family-level risk factors; and (2) to examine agreement between caseworkers' risk assessments and any subsequent report, or reports, of maltreatment. METHOD: Data are from the baseline, 12-month, and 18-month assessments of the National Survey for Child and Adolescent Well-Being (NSCAW), a nationally representative sample of youth and families who were the subjects of allegations of maltreatment investigated by child welfare agencies. The sample consisted of a subset of NSCAW participants: cases with a report of child physical abuse or neglect who were not placed in out-of-home care (N=2,139). RESULTS: Analyses indicated that parent-level risk factors and a prior report of maltreatment were most strongly associated with caseworkers' assessments of risk for both physical abuse and neglect cases. A smaller set of factors, which varied by the type of maltreatment, were associated with a subsequent report of maltreatment. Despite some overlap in correlates of risk assessment and subsequent reports, analyses indicated that agreement between caseworkers' assessments of risk and re-reports was low. CONCLUSIONS: Findings suggest that although caseworkers' assessments were associated with a limited set of risk factors from the literature, few of these factors also were associated with a recurrent report of maltreatment. Correspondence between caseworkers' assessments of risk and a subsequent report of maltreatment was low, suggesting that considerable work may be needed to improve accuracy and identification of cases most at risk. PRACTICE IMPLICATIONS: This study provides information to assist caseworkers, administrators, and policymakers in thinking critically about risk assessment policies and procedures. Although caseworkers' assessments of risk were associated with some of the empirical predictors of recurrent maltreatment, their assessments were only slightly better than guessing. Agreement between caseworkers' risk assessments and actual subsequent reports was better for low-risk cases, but primarily because the majority of cases did not have a subsequent report during the study period. Clearly, considerable improvement in risk assessment is needed so that at-risk families can be better identified and the limited services available can be directed toward those most in need. 相似文献
