The authors combine historical and sociological institutional analysis to show that despite the political and socio‐economic transformation in 1990s, the institutional development during and before the communist era provides the best explanation for current childcare policies in Central Europe. While most authors have concentrated on policy changes that have taken place in the region since 1989, this article concentrates on the historical roots of these policies and shows that today's policies are highly influenced by a certain dynamics that had already emerged under communist rule. It shows that a historical institutional approach, which analyses the ‘gendered logic of appropriateness’ and policy legacies at various critical junctures, can explain why family policies in Central Europe had already begun to differ during the communist era, why these main differences continue and why even the changes that have taken place follow logically from historical‐institutional developments.  相似文献

When designing a clinical trial there is a need to design a study that achieves the objectives of a trial both efficiently and with minimum resources. This paper describes seven trial designs that could possibly be used in clinical development and highlights how a design although not optimal for an individual study may be optimal for a wider clinical program.  相似文献

ABSTRACT

Objective: Financial strain may directly or indirectly (i.e., through perceived stress) impact students’ psychological symptoms and academic and social integration, yet few studies have tested these relationships. The authors explored the mediating effect of perceived stress on the relationship between financial strain and 2 important outcomes: psychological symptomology and academic and social integration. Participants: Participants were 157 undergraduate students. Data were collected from December 2013 to March 2014. Methods: Cross-sectional data collection conducted using online survey software. Results: It was found that perceived stress mediated the relationship between financial strain and (a) psychological symptomology and (b) academic and social integration. Both models included first-generation status as a covariate. Conclusions: Results suggest that perceived stress is an important intervention target for reducing psychological symptoms and improving academic and social integration for undergraduate students. Implications for university health centers and mental health professionals include incorporating a public health model to minimize stress risk.  相似文献

ABSTRACT

Objective: The present study extends research on campus smoking bans by examining where smokers are violating the policy at a large university in the southeastern region of the United States. Participants: The data collection was conducted by one graduate student from the university in August of 2014. Methods: A global positioning system device was used to collect the geo-coordinates of littered cigarette butts as a proxy measure for smoking violations. Results: A hot spot analysis found a number of spatial concentrations on campus, largely around classroom and administrative buildings along with parking lots and garages. Conclusions: The implications of such findings can direct enforcement to target these areas in order to reduce offenses and fulfill the initial goals of policy-makers and university administrators who support smoke-free campuses.  相似文献

This essay takes up the issue of anal sexuality among gay men in order to consider the relationship between bodily and psychic penetrability. The lack of recognition some gay men may experience with this aspect of their sexuality suggests the importance that feeling “mentalized” (e.g., Fonagy and Target, 1993 Fonagy , P. & Target , M. ( 1993 ). Aggression and the psychological self . International Journal of Psycho-Analysis , 74 , 471485 .[PubMed], [Web of Science ®] [Google Scholar]) may play in adult life. Drawing on early gay liberation and ACT UP-era theorizing about anal sex and an extended clinical example, I explore the meanings of gay men's wishes to (and fears of) penetrate and be penetrated on both bodily and psychic levels as well as the consequences of feeling denied entry. My consideration of these matters becomes in turn an occasion for a critical assessment of the mentalization concept itself.  相似文献

This research examines the sentencing outcomes of convicted child sexual offenders from data collected over an eight year period. Multiple regression and nominal log linear regression are used to examine length of prison sentence, length of probation sentence, and whether the convicted offender is actually sent to prison or to probation. While many independent variables appear to be related to sentence outcome, they fall into three categories: characteristics of the offender, characteristics of the victim, and characteristics of the crime. Additionally, while many variables appear related at the bivariate level, when multivariate analysis is applied, fewer variables remain significant, and these are mostly from the characteristics of the offense.  相似文献

Two samples, male college students and convicted male child sex offenders, are compared on their abilities to accurately estimate the age group of a series of photographs of a sole female ranging in age from 11 to 29. Both samples tend to overestimate the age group of the subject photos, and no significant difference was found between college students and convicted child sex offenders in their ability to estimate the age of females. Both groups are compared demographically, and only limited differences were found. The implications are discussed in regard to theory and prevention of child sexual abuse.  相似文献

A small literature has addressed psychotherapy with lesbian, gay, bisexual, and transgender (LGBT) samples over the past two decades. Older adults have also been investigated in a growing number of psychotherapy research studies. However, psychotherapy specifically with LGBT older adults has not received adequate investigation. This review relies on converging lines of research to provide an integrated discussion of evidence-based psychological treatments (EBTs) with current research and clinical observations in the field of gerontology and suggests ways in which these topics can inform psychotherapy practice with LGBT older adults. We summarize current research on aging in several areas of practical interest to psychotherapists seeking to apply EBTs in their work with LGBT older adults. These areas include: adult development, coping, stigmatization, social context, and the effects of cohort membership. The results of these studies belie stereotypes regarding both the aging process, in general, and more specifically LGBT older adulthood, with significant implications for the practice of psychotherapy. EBTs are adaptable to a variety of issues encountered in later life by LGBT older adults, and these modifications to therapeutic technique are addressed throughout.  相似文献

Prior quantitative research with gay and bisexual men (GBM) has documented high rates of sexual risk behavior during recreational travel. Although some associations are known (e.g., substance use at the tourist destination is associated with sexual risk), less is known about GBM’s motivations for travel and the cognitive and attitudinal factors that influence their sexual behavior while vacationing. In the present study, we conducted qualitative interviews with 46 GBM recruited from three popular gay tourist destinations. Using the Health Belief Model (HBM) as a guiding theoretical framework, the findings of the study revealed that the gay-friendly, tropical, relaxing environments resulted in men letting their guard down and engaging in more risk than when they are at home. Various barriers such as peer pressure and substance use affect GBM’s ability to engage in healthier behaviors while traveling, with condom negotiation and HIV status disclosure as additional issues that impact the sex practices of this population. Results highlight the applicability of HBM constructs to provide insight for intervention development for this population.  相似文献
