Alcohol use and strenuous physical activity in college students: A longitudinal test of 2 explanatory models of health behavior

Objective: To help clarify the effect of gender on the bidirectional relationship between alcohol use and strenuous physical activity in college students. Participants: Five hundred twenty-four (52% female) college students recruited in August 2008 and 2009 and followed up in April 2009 and April 2011, respectively. Methods: Participants reported their alcohol use and strenuous physical activity on 2 occasions (baseline and follow-up) spaced approximately 1 or 2 years apart. Results: For females, alcohol use quantity at baseline was associated with increased strenuous physical activity at 1- and 2-year follow-ups, and alcohol use frequency at baseline was associated with decreased strenuous physical activity at 2-year follow-up. For males, alcohol use frequency at baseline predicted decreased strenuous physical activity at 1-year follow-up. Conclusions: Gender differences may be explained from an eating disorders perspective such that women use physical activity as a compensatory strategy to combat potential weight gain from calories consumed during alcohol use.     

Looking at intra-European mobilities through migrant types: young Spanish and Polish migrants in London and The Hague

This paper echoes the need to further explore the social effects of European Union integration by examining the increasingly complex and diverse scenario of intra-European mobility. Much research has focused on the intensification of East-to-West migrant flows after the enlargements of 2004 and 2007, inspiring a rich conceptualization of migrant typologies. Theoretically, this paper argues that some of these typologies can be extrapolated to better understand the experiences of other European movers. Empirically, it offers a qualitative and comparative analysis of diverse European young adults’ experiences of mobility: 8 Polish citizens in The Hague and 10 Spaniards in London. The analysis is based on four main dimensions derived from the literature: (1) Motivations to migrate, (2) Labour market participation, (3) Attachments and transnational ties and (4) Family composition and future outlooks. Results map individual differences and similarities contextualized by generational, gendered, educational and socio-economic aspects.     

Workplace aggression against health care workers,law enforcement officials,and bus drivers: Differences in prevalence,perceptions, and psychological consequences

Investigations into workplace aggression (WPA) remain largely occupation specific, with few studies using a comparative approach. The aim of the present study was to compare the health care, law enforcement, and public transportation sectors with regards to the prevalence of different types of WPA, the perceptions of workers toward WPA, and the psychological consequences of such acts. A cross-sectional survey was completed by 1,774 workers in Canada. Multinomial regressions were utilized to address the objectives. Findings revealed that verbal abuse victimization was particularly common in bus drivers, witnessing death threats was most frequent among law enforcement officials, and witnessing all types of WPA was most common among health care workers. Although bus drivers did not normalize WPA, they feared complaining about violence to their employer and thought it useless to talk it about unless wounds were visible. Fear of complaining about violence to colleagues was prevalent in health care and law enforcement, both sectors in which WPA was normalized. Finally, flashbacks and irritability following WPA were most likely to affect bus drivers whereas health care workers experienced hypervigilance to a greater extent. Strategies to tailor primary, secondary, and tertiary prevention according to these distinctions are suggested to offer a better-informed response to WPA.

Psychophysiological Reactivity in Child Sexual Abuse

Sexual abuse has physiological and emotional implications. The purpose of this study is to evaluate the neurobiological sequels of childhood sexual trauma by monitoring physiological variables among sexually abused girls and women compared to controls. We assessed posttrauma and traumatic life events of 35 females sexually abused in their childhood (age range 7–51 years) and 25 control females (age range 7–54 years). Electroencephalography, frontalis electromyography, electrodermal activity, and heart rate parameters were recorded while watching sets of pictures representing neutral and trauma-suggestive stimuli. A minority of participants met the Diagnostic and Statistical Manual of Mental Disorders criteria for post-traumatic stress disorder. Abused females displayed significant elevations in heart rate, electromyography, and electroencephalography while viewing allusive stimuli and elevated heart rate while viewing neutral stimuli. The dysfunctional regulation of the physiological stress system associated with child sexual abuse may endanger the victims with various stress and anxiety disorders.     

The Tempo of Sexual Activity and Later Relationship Quality

Rapid sexual involvement may have adverse long‐term implications for relationship quality. This study examined the tempo of sexual intimacy and subsequent relationship quality in a sample of married and cohabiting men and women. Data come from the Marital and Relationship Survey, which provides information on nearly 600 low‐ to moderate‐income couples living with minor children. Over one third of respondents became sexually involved within the first month of the relationship. Bivariate results suggested that delaying sexual involvement was associated with higher relationship quality across several dimensions. The multivariate results indicated that the speed of entry into sexual relationships was negatively associated with marital quality, but only among women. The association between relationship tempo and relationship quality was largely driven by cohabitation. Cohabiting may result in poorer quality relationship because rapid sexual involvement early in the romantic relationship is associated with entrance into shared living.     

Processes Employed by Social Work Practitioners in Child Welfare for Exchanging and Using Knowledge

Organisations in the health and social services sector expend a considerable amount of energy promoting the implementation of better practices and research data use in their establishments. In the field of social work, several studies suggest that social work practitioners do not make great use of scientific knowledge and tend to favour knowledge acquired from their colleagues or through their own occupational experience. However, interactions between types of knowledge are rarely analyzed in explanations proposed by the scientific literature. Based on research conducted with social work practitioners in child welfare, this article discusses the different ways that they acquire knowledge.     

近代西方传教士在河北地区的医疗卫生活动

近代以来,西方传教士在河北地区开展了一些医疗卫生活动,如开办医院、诊疗所,进行巡回医疗、卫生防疫、兵灾救护等.传教士的医疗卫生活动在一定程度上改变了河北地区落后的医疗卫生状况,救治了大批病患,促使民众卫生观念开始发生转变,推动河北地区医疗卫生向近代化转型.但由于自身及社会历史原因,传教士开展的医疗卫生活动也带有一定局限性,制约了其医疗卫生功能的发挥.
