Contextual, mother‐, child‐, and father‐level variables were examined in association with fathers' emotion talk to infants during a shared picture book activity, in an ethnically diverse, low‐income sample (N = 549). Significant main effects included the rate of emotion talk from fathers' romantic partners (i.e., the infant's mother), infant attention and distress, and sensitive parenting. Significant interactions were also found. Higher income African American fathers referred to negative emotions more than non‐African American higher income fathers. In addition, African American fathers who demonstrated more negative and intrusive parenting referred to positive emotions more than non‐African American fathers who demonstrated negative and intrusive parenting. Our findings support family systems theory and, specifically, the interdependence of individuals' behaviors within the family unit. Interaction effects are discussed with respect to cultural variation in beliefs about parenting behaviors and the cultural experience of African Americans, including the Black cultural experience and the minority experience.  相似文献

The purpose of this article is to enrich our conceptual understanding of ethnography through principles of design by offering a blueprint for ethnographic ways of knowing. Drawing on published ethnographic research, this article develops and defines principles of design that help facilitate the process and product of ethnographic research. Through the metaphor of an architectural blueprint, we consider the epistemological value of identifying foundational principles supporting ethnographic research and writing. The architectural blueprint offers a foundation for creating, writing, revising, teaching, and evaluating ethnographic scholarship. The article closes with a discussion of the utility of the metaphor as well as how other metaphors that currently guide ethnographic research could be used in tandem with the blueprint metaphor.  相似文献

Evaluation designs for social programs are developed assuming minimal or no disruption from external shocks, such as natural disasters. This is because extremely rare shocks may not make it worthwhile to account for them in the design. Among extreme shocks is the 2010 Chile earthquake. Un Buen Comienzo (UBC), an ongoing early childhood program in Chile, was directly affected by the earthquake. This article discusses (a) the factors the UBC team considered for deciding whether to put on hold or continue implementation and data collection for this experimental study; and (b) how the team reached consensus on those decisions. A lesson learned is that the use of an experimental design for UBC insured that the evaluation's internal validity was not compromised by the earthquake's consequences, although cohort comparisons were compromised. Other lessons can be transferred to other contexts where external shocks affect an ongoing experimental or quasi-experimental impact evaluation.  相似文献

Online grief communities represent relatively new forms of peer support. However, the degree to which they are helpful for individual grieving processes is unknown. To date, no research has evaluated the type or quality of support exchanged in online grief communities. To begin to address these questions, this study analyzed 564 messages from internet grief websites to: (1) classify the type of helping skills used, and (2) extract themes contained in the content of the messages. Messages selected for analysis were the first response to an original post, assuming they would be the first effort to provide support to a grieving individual. Results revealed a majority of responses contained self-disclosure. Themes in the messages suggested provision of more than "one-way" support; messages themes also included exchanging hope for the future by sharing one's own story, validating the grief experience, providing resources, and exchanging psychosocial support. Clinical implications and research recommendations are discussed.  相似文献

This article describes the annual evolution of nuptiality in Spain from the beginning of the last century up to the present day. The analysis is based on data on first marriages from population registration data (Movimiento Natural de Población) after various adjustment and estimation operations. This source has an advantage with respect to census data, since it allows us to follow the annual nuptiality fluctuations that are very sensitive to prevailing social and economic conditions. Over the long term, the phases of nuptiality in Spain are comparable to those observed in Western Europe. However, leaving aside the period disturbed by the Civil War (1936–1939), Spain does exhibit some particular features: a long interlude from 1940 to 1959 marked by late marriage, rooted in the long depression of the Spanish economy; a prolonged rise in nuptiality which lasted until the end of the 1970s, corresponding to the late arrival of the first oil shock in Spain; and finally, a certain delay in the decline of marriage, accompanied—since the early 2000s only—by a parallel diffusion of cohabitation. Last, Spain is converging with Europe in another aspect that is seldom taken into account. While, from 1950 to 1980, it was one of the few European countries to register a first marriage rate unfavourable to women, the reversal of this trend since the 1980s has brought Spain closer to the majority of its neighbours.  相似文献

In this article, the authors describe relatively recent efforts by scientific research agencies to promote, through various funding programs, the integration of social sciences and humanities with the natural sciences. This "integrated" approach seeks to study science through a broader interdisciplinary lens in order to better anticipate, understand, and address its ethical, legal, and social implications. The authors review the origins and evolution of this trend, as well the arguments which have been formulated by both proponents and critics of integration. By using Genome Canada's "GE(3)LS" Research Program as a case study, the authors discuss the successes and continuing challenges of this model based on evaluation results available to date. The authors then go on to examine and compare three possible models for improving the future success of the GE(3)LS research program, including: 1) enhancing the current integrated research approach through incremental refinements based on concrete evidence and lessons learned; 2) promoting greater interaction and synergy across GE(3)LS research projects through a deliberate, systematic and coordinated "hub and spoke" approach; and 3) taking a broad programmatic approach to GE(3)LS research by creating a central resource of available expertise and advisory capacity.  相似文献

高校教师从事的是一种学术职业。高校教师的主观幸福感是在与教学和科研相关的学术职业活动过程中得到的一种精神满足和情感体验。学术环境是影响高校教师主观幸福感的重要因素之一。高校应当通过创设各种条件,满足教师在学术活动中内在的心理需求;应当逐步去行政化,强化学术权力在学校生活中的权威,促进学术环境的优化,提升教师的主观幸福感。  相似文献

进城务工人员作为我们当今社会的弱势群体,他们子女的教育问题是影响我国构建社会主义和谐社会的重要因素。通过分析"杀鱼弟"作为义务教育适龄儿童,不做读书郎却愿为杀鱼工,发现隐藏在这一事件背后的是一个严重的教育问题,即进城务工人员子女的失学问题。采用问卷调查和文献研究两种研究方法,对进城务工人员子女失学问题从失学因素、隐性失学现象、失学所带来的危害等几个方面展开论述,并在此基础上提出具有可行性的对策。  相似文献

综合利用岩芯、测井以及各种分析化验资料,运用储层沉积学、岩石学和成岩作用等相关理论,详细总结了大牛地气田致密砂岩储层的成因。研究结果表明,沉积微相在宏观上控制了储层物性的空间分布,成岩作用决定了砂岩内部储集空间特征和储集性能,主要表现在较强的压实作用和胶结作用使砂岩的原生孔隙很少得以保存,而溶蚀作用有条件地改善了储层的储集性能,微裂缝只是在一定程度上改善了砂岩的渗透性,但也加剧了储层的非均质性。在此研究基础上,从沉积相、岩石学特征、成岩作用、孔渗特征等方面优选地质评价参数,在目的层划分出4类储层,其中Ⅰ类高产层主要是河道砂体复合带,其具有自然伽马曲线低值、自然电位曲线显著负异常等测井响应特征,碎屑颗粒粗,储层岩石表现为石英含量高,以残余粒间孔或粒间溶孔为主的特征。  相似文献

Objective. Few social scientists have examined how Internet usage, including using the Internet for health purposes, may affect mental health. This study assesses whether the type or amount of online health activities and the timing of Internet use are associated with psychological distress.Methods. We use data from the National Cancer Institute's 2005 Health Information National Trends Survey.Results. When we compare Internet users to non-Internet users, using the Internet and using the Internet for health purposes are negatively associated with distress. However, among Internet users, the number of online health activities is positively associated with distress. Greater distress is also associated with using the Internet on weekdays and looking online for information on sun protection.Conclusions. Internet usage is not necessarily positively associated with psychological distress. The effects depend on the type, amount, and timing of Internet usage.  相似文献
