Understanding the experience of women who become mothers during their teenage years is central to ensuring that the support that is offered is appropriate to meet their needs. This paper reports on a small part of a larger ethnographic study that captured the lived experience of young mothers who were between the ages of 16 and 19 years that potentially typifies and illuminates the experiences of young women who become mothers in their teenage years. By collecting data from narrative interviews as well as participant and non‐participant observations over an extended period of time it was possible to identify how the young women experienced a range of difficulties as they made their transition into motherhood. Drawing on the findings, this paper argues that this transition for teenage mothers can be significantly different from the experience of older mothers, and it identifies the importance of appropriate support to mediate the challenges that they face. Understanding the young women's journey to ‘becoming’ is critical when planning services because if their experience of support is negative, it can lead to increased levels of maternal stress and reluctance to engage with support services.  相似文献

人口空间动态与区域经济发展的耦合关系是同城化区域间共同面对的重要课题。本文在解构人口空间动态维度主体的基础上,将人口空间动态的诉求机制与动因机理架构于更低交易费用的利益诉求之上,解析人口空间动态的模式选择,深入探讨人口空间动态与区域经济发展的耦合关联性。在此基础上,提出引导人口流动与合理分布的策略。研究成果将有助于更好地理解同城化态势下人口空间演变的动因机理,为同城区域的经济发展、城市规划、文化交融等方面的科学设计提供重要参考。  相似文献

伴随社会经济的迅猛发展和城市化步伐的加快,生态破坏、环境污染等问题日益加剧。生物界自然平衡状态的打破导致近年来我国各类公共卫生危机频发,处于公共卫生事件的高发期,“90后”作为一个特殊的青少年群体,由于其身心机能发育尚未成熟,不但是此类事件中最主要的易感人群,更容易产生各类心理障碍与行为问题。现代健康观念的树立和综合健康素养的提升在这一阶段尤为关键。研究发现,“90后”青少年的健康观念趋于科学理性,健康自我管理能力和习惯养成有待提升:对健康危机的忧患意识较强,危机状态下的心理承受能力较弱;具备一定的公民责任意识和行为自律意识,但面对一些较为复杂的社会现象,现代法制观念和人文关怀意识仍有所欠缺  相似文献

Extending previous work on hedge fund return predictability, this paper introduces the idea of modelling the conditional distribution of hedge fund returns using Student's t full-factor multivariate GARCH models. This class of models takes into account the stylized facts of hedge fund return series, that is, heteroskedasticity, fat tails and deviations from normality. For the proposed class of multivariate predictive regression models, we derive analytic expressions for the score and the Hessian matrix, which can be used within classical and Bayesian inferential procedures to estimate the model parameters, as well as to compare different predictive regression models. We propose a Bayesian approach to model comparison which provides posterior probabilities for various predictive models that can be used for model averaging. Our empirical application indicates that accounting for fat tails and time-varying covariances/correlations provides a more appropriate modelling approach of the underlying dynamics of financial series and improves our ability to predict hedge fund returns.  相似文献

美国著名汉学家史景迁(Jonathan D. Spence)从文化认知、文化比较的研究视域出发,对孔子进行了跨文化解读与传播。在史景迁“去偶像化”的观照方式下,孔子被解码、建构为具备鲜明个性特质的人文主义者及令人尊重的教育者形象。同时,史景迁致力于厘清西方一般认知中对孔子及其思想的诸多误读,并努力唤起西方受众对孔子当代意义的认同。  相似文献

Asymptotic confidence (delta) intervals and intervals based upon the use of Fieller's theorem are alternative methods for constructing intervals for the <$>\gamma<$>% effective doses (ED<$>_\gamma<$>). Sitter and Wu (1993) provided a comparison of the two approaches for the ED<$>_{50}<$>, for the case in which a logistic dose response curve is assumed. They showed that the Fieller intervals are generally superior. In this paper, we introduce two new families of intervals, both of which include the delta and Fieller intervals as special cases. In addition we consider interval estimation of the ED<$>_{90}<$> as well as the ED<$>_{50}<$>. We provide a comparison of the various methods for the problem of constructing a confidence interval for the ED<$>_\gamma<$>.  相似文献

This article uses a comparative approach to discuss women's access to property using evidence collected from field research conducted on two distinct communities of Istanbul: one secular and one Islamic. The two groups of women possess distinctly different views of the world and how it is organized. This is particularly the case concerning gender where secular women put forth a view rooted in the sameness of the genders where the Islamic women were clear in their commitment to the idea of difference. These attitudes toward the equality and difference of the genders structures the relations of these women to property and the process of inheritance.  相似文献
