This paper exploits a Danish spatial dispersal policy on refugees, which can be regarded as a natural experiment to investigate the influence of regional factors on recent immigrants’ location choices. The main push factors are lack of co-nationals and immigrants. Additional push factors are lack of rental, including social, housing and lack of institutions for qualifying education, which explain why recent immigrants are attracted to large cities. Finally, placed refugees tend to leave locations with relatively high regional unemployment, and there is indirect evidence of welfare seeking.

Parenting may be particularly challenging for substance‐dependent mothers who have grown up with parents who themselves had substance use disorders (SUDs). The aim of this study was to explore how substance‐dependent mothers describe their childhood experiences with substance‐abusing parents and the association between these earlier experiences and their own role as caregivers. Using purposeful sampling, mothers admitted for 1 year to a family ward at a substance abuse clinic were approached. Through in‐depth, qualitative interviews, nine substance‐dependent mothers described their lives in the form of present, past and future tense. The findings indicate that substance‐dependent women, who have experienced SUDs in their families of origin, face several major challenges when they become mothers. Some describe having lived their whole lives ‘on the edge of society'. This makes their rehabilitation process more complex. All mothers work to abstain from substances, process traumatic experiences and integrate their family into society. They need help to build supportive social networks and to establish a safe and predictable family environment for themselves and their children. The therapeutic implications of these findings will be discussed.  相似文献

A positive youth development perspective focuses on recognizing psychosocial strengths and providing social environments that contribute to the development of these in children and adolescents. Bereavement camps can provide such an environment as they help children cope with the death of someone close. The purpose of this study was to observe bereavement camps through the lens of positive youth development to determine the applicability of the eight features of positive developmental settings for describing bereavement camps (safety, appropriate structure, supportive relationships, opportunities to belong, positive norms, support for efficacy, skill building opportunities, integration of family and community). Observational notes were recorded by researchers during on-site visits to three different weekend bereavement camps. Results identified how each element of positive developmental settings was exemplified in either typical camp activities or bereavement-focused activities. For example, assigning campers to cabin groups based on age and gender provided opportunities to belong, and giving campers a comfort object and a big buddy provided supportive relationships. Findings were used to create a positive developmental settings observation checklist for use by bereavement camp practitioners to assess the extent to which each camp provides the requisite elements for promoting positive youth development.  相似文献

Most of the studies on the determinants of individual gambling behaviour rely on cognitive theories. In our study, we argue that, besides cognitive factors, several social factors might play an important role as well. We analyse data from an ad hoc webmail survey conducted on about 2000 undergraduate students enrolled in a large public university in the Northern Italy in the academic year 2012–13. Using a variety of statistical techniques (standard regression models, boosted regression trees and structural equations models), we show that social variables affect both participation in gambling in the past year and latent gambling propensity. In particular, controlling for several proxies for individual cognitive ability and understanding of probability, gambling propensity is positively affected by the degree of gambling in the social surrounding (parents, peers, neighbourhood) and the acceptability of gambling activities to the individual. Moreover, in our sample of college students the role of social factors appears to be larger than that of cognitive factors, and this is consistent across different types of models and specifications.  相似文献

The majority of LGBTQ psychological research focuses on dysfunction. The exclusion of strengths-based perspectives in LGBTQ psychology limits the understanding of LGBTQ mental health. In this article we report experiences that young bisexual and other nonmonosexual people perceive as affirming of their sexual identity. A 28-day, daily diary study was used to investigate whether bisexual-identified participants encountered positive experiences related to their sexual identity, and which type of experiences they perceived to be positive. Using a constructivist grounded theory approach, participants’ experiences were organized according to a social ecological model. Experiences were reported at the intrapersonal, interpersonal, and institutional levels, but most positive sexual identity experiences occurred at the interpersonal level. Implications for positive health outcome research and the integration of positive psychology with LGBTQ psychology are discussed, as well as study limitations.  相似文献

We examined 359 women aged 45–65 years who visited Jordan University Hospital between February and November 2014. The menopausal symptoms were assessed using a validated Arabic version of the menopause rating scale. The mean age at menopause was 49.4 years. Women aged 50–55 years more frequently exhibited hot flushes and vaginal dryness. Although premenopausal women were 1.5 times more likely to experience irritability, perimenopausal women were more likely to experience hot flushes, physical and mental irritability, sexual problems, vaginal dryness, and joint and muscular discomfort. Hence, health care providers should focus on women at all stages of life.  相似文献

2016年1月1日起实施的全面二孩政策能否有效地鼓励民众的生育行为,这关乎到我国未来几十年合理调整人口结构、稳固新常态发展的成功与否。本文通过对我国1980-2015年有关生育意愿的国内外文献总结回顾,将生育意愿的内涵界定为数量、时间、性别、动机四个维度,并在此基础上结合国内外学者们的研究归纳得出影响生育意愿的五个方面因素:政策、经济、观念、教育、年龄,以期在新政策背景下展望未来,借鉴国外发展的经验,做好养老、医疗、就业、教育方面的准备措施来迎接全面二孩时代,并为有关生育意愿的进一步研究提供参考。  相似文献

Background

During the last decades, there has been an alarming and dramatic increase in the number of cesarean births in both developed and undeveloped countries. This increase has not been clinically justified but, nevertheless, has raised an important number of issues.

Aim

The aim of this study was to determine the risk factors associated with the high cesarean section rates in Lebanon.

Methods

This study is based on a sample of 29,270 Lebanese women who were pregnant between 2000 and 2015. Among these, 14,327 gave birth by cesarean section and 14,943 gave birth vaginally. To identify the risk factors of cesarean section, logistic regression was applied as a statistical method using the SPSS statistical package.

Findings

Of the 29,270 pregnant women included in the study, 49% had cesarean sections while 51% gave birth vaginally. Repeat cesarean section accounted for 23% while vaginal birth after cesarean accounted for only 0.2% of deliveries. In addition, weekdays were associated with a preference of providers to carry out more cesarean sections. According to an analysis of our data using logistic regression, the risk factors associated with the increase in cesarean section rates were advanced maternal age, elective cesarean section, malpresentation of fetus, multiple birth, prolonged pregnancy, prolonged labor, and fetal distress.

Conclusion

Based on these results, it is recommended that a new health policy be implemented to reduce the number of unnecessary cesarean deliveries in Lebanon.  相似文献

在西方哲学的知识论传统中,哲学家们倾向于把主体和客体理解为他们各自规范的知识观念所要求的必要功能。在古代哲学家们的思想中,自然和客体知识的可能性问题受到主要讨论,但没有明确地思考主体问题。近现代主体观的兴起所依赖的个体观念只是在后来的基督教思想中才进入哲学传统。以个体观念为先决条件的个体责任的观念已然现身于奥古斯丁的著作中。奥古斯丁对自我的直接诉求,天才般地开启了笛卡尔的"我思"观念的源头。由此形成的笛卡尔的知识主体,是一个抽象的认识论的假定,一个消极的旁观者。康德有限度地追随了笛卡尔的主体观念,但把笛卡尔的作为消极的旁观者的主体改造成了积极的行动者。康德在知识观上的这种"哥白尼式的"革命,构成了随后德国唯心主义主体观的基础。整体上看,康德之后的主体观存在着一种越来越向笛卡尔的主体观和古希腊的主体观隐退的明显倾向,及至海德格尔后期和后结构主义,这种倾向最终导致了向古希腊知识主体的全面回归。  相似文献

学术期刊是学术和学科建设的重要阵地,应以学术性作为编辑审稿工作的唯一标准。然而,在现有学术评价体制的影响下,这一工作受到了诸多非学术因素的消极干扰,如以作者身份的高低而非稿件质量的高低来取舍稿件。这一非学术性倾向直接影响了审稿的公正性,也削弱了编辑审稿活动的意义,是学术评价异化的一种反映,不利于学术研究的正常进行和健康发展。编辑应该强化责任意识,自觉克服心理因素,排除思维定势,提高学术判断力,重视学术新人的发现和扶持,从而有效发挥学术期刊在学术和学科建设中的积极作用。  相似文献
