BackgroundHaving a positive childbirth experience is an increasingly valued outcome. Few studies evaluated the women’s satisfaction with childbirth through face-to-face interviews out of the health service environment. The objective of this study was to identify factors associated with a higher level of satisfaction with the childbirth experience among Brazilian women.MethodsThis cross-sectional study involved 287 women giving birth in two hospitals in southern Brazil. Women who gave birth to healthy newborns at term were randomly selected. Face-to-face interviews were conducted 31–37 days after delivery, at the mothers’ homes, using a structured questionnaire. Satisfaction with the childbirth experience was measured using a Likert-type scale ranging from very satisfied to very dissatisfied. Prevalence ratios (PR) were estimated using Poisson regression with robust variance.ResultsFollowing hierarchical multivariate analysis, the following factors remained associated with a higher level of satisfaction with the childbirth experience: being satisfied with antenatal care (PR = 1.30; 95% confidence interval [95%CI] = 1.06−1.59), understanding the information provided by health professionals during labor and delivery (PR = 1.40; 95%CI = 1.01−1.95), not having reported disrespect and abuse (PR = 1.53; 95%CI = 1.01−2.31), and having had the baby put to the breast within the first hour of life (PR = 1.63; 95%CI = 1.26−2.11). No association was observed with type of delivery or hospital status (public or private).ConclusionsA higher level of satisfaction with the childbirth experience is related to satisfactory antenatal care, a non-abusive, respectful, and informative environment during childbirth, and to the opportunity to breastfeed the baby within the first hour of life. In clinical practice, greater attention to these basic principles of care during pregnancy and delivery could provide more positive experiences during birth.  相似文献

在威廉姆森交易成本理论的基础上,探讨交易特性对农业合作社与农户之间合约选择的影响,发现社员身份特征在其中发挥调节作用。研究结果表明,资产专用性、风险性和规模性对农业合作社与农户之间签订一体化程度不同的合约具有明显的影响,其中,专用性对合约一体化程度的影响是正向的;而风险性和规模性对双方签订一体化程度更高的合约影响是负向的。但和非社员相比,股东身份使资产专用性对双方签订一体化程度更高合约的正向影响作用变大;并使风险性、规模性对双方签订一体化程度更高合约的负向影响作用变小,即股东身份作为调节变量发挥了显著效应。  相似文献

For social work education in the Netherlands, the rapid transition towards superdiversity means that its capacity to adapt to this new reality and to adjust to diverse students’ backgrounds is fiercely challenged. The key aim of this article is to discuss how social work educators are dealing with the unsettling challenges of increasing diversity, based on the research outcomes of an explorative study amongst Turkish–Dutch and Moroccan–Dutch female professionals. Two different groups of educators were asked to comment on the outcomes of this study. One of the dilemmas for educators is to determine what can be considered supportive and inclusive and as reducing inequality in education. The authors used two key theoretical concepts, ‘superdiversity’ and ‘the capability approach’. These theoretical perspectives were used to deconstruct the rather massive concepts of diversity and social justice, by emphasising contextual approaches. Both perspectives stress the urgent need to involve students as ‘active agents of change’, by building a social work community to stimulate and facilitate an on-going dialogue. To successfully fulfil a pivotal role in the upward mobility or emancipation of ethnic minority students, social work education needs to be adjusted to accommodate diverse student groups.  相似文献

Abstract

Virtual reality (VR) has emerged as a promising technological intervention for anxiety disorders. However, there are no existing standards and best practices to evaluate the effectiveness of environments to achieve their intervention goals. The purpose of this study was to develop a VR intervention for student veterans with social anxiety disorder and test feasibility utilizing a three-stage development model. The development of a therapeutic VR environment may benefit from an interdisciplinary collaboration of researchers from various fields of study. Utilizing three stages of prototyping with two virtual reality platforms, fully immersive video (n?=?6) and three-dimensional (3-D) immersive virtual reality (n?=?8), the research team designed an intervention for student veterans with social anxiety disorder, testing bio-reactivity of participants. Results of prototyping include user feedback validating increased stress levels and increased bio-reactivity specifically in galvanic skin response and heart rate elevation. Implications include the use of 360° video for prototyping 3-D virtual reality interventions.  相似文献

Abstract

In this essay, we offer our stories of family and migration under a Donald Trump presidency. We are a lesbian couple; one of us is a citizen of the United States while the other is a citizen of a Muslim country. We use autoethnographic methods to explore and interrogate our “messy and fabulous” journey of liminality; our journey of belonging and exclusion, where we grapple with issues related to sexuality, family, career, and citizenship. Our “voices” are used both individually and in unison, to highlight our intersectional and relational selves. We intend this work to contribute to the many ways we can better understand and appreciate the bountiful and colorful vistas of lesbian families’ migrant experiences.  相似文献

中国当代文学在进入“新时期”后随着主流意识形态文艺制度的松绑而发生了重要的身份转向。这种“转向”一方面表现为作家写作心态的重要变化,另一方面也表现为文学风格的根本变化,同时还表现为文学启蒙主义现代性使命的重新回归。中国当代文学在进入“新时期”后的这种复杂现代性身份转型,为20世纪80年代后的中国社会现代性建设提供了重要的想象支持。  相似文献

Contemporary theories on leadership development emphasize the importance of having a leader identity in building leadership skills and functioning effectively as leaders. We build on this approach by unpacking the role leader identity plays in the leader emergence process. Taking the perspective that leadership is a dynamic social process between group members, we propose a social network-based process model whereby leader role identity predicts network centrality (i.e., betweenness and indegree), which then contributes to leader emergence. We test our model using a sample of 88 cadets participating in a leadership development training course. In support of our model, cadets who possess a stronger leader role identity at the beginning of the course were more likely to emerge as leaders. However this relationship was only mediated by one form of network centrality, indegree centrality, reflecting one's ability to build relationships within one's group. Implications for research and practice are discussed.  相似文献

目前有许多研究将两阶段DEA模型应用到科技创新活动当中,一般将创新活动分为研发和转化两个阶段,为了进一步探讨不同转移转化方式下科技成果的转化效率以获得更多的详细信息,本文拓展了传统的两阶段DEA模型,考虑了嵌套并联结构的两阶段网络DEA模型,将科技创新活动分为科技成果研发阶段和科技成果转化阶段,并将科技成果转化阶段分为内部转化和外部转化两个并联子系统。本文选取14家中科院院属单位作为被评价对象,应用加权加法分解方法计算整体效率和各阶段子效率。通过将本文模型与传统两阶段模型进行对比发现,传统模型会低估科技成果转化效率。结果表明:整体科技创新效率均值偏低,科技成果研发效率均值高于科技成果转化效率均值,科技成果转化效率仍有很大的提升空间。科技成果转化阶段中内部转化效率普遍较高但是外部转化效率普遍较低,较低的外部转化效率是导致科技成果转化效率低下的主要原因。最后,本文将所有被评价单位分为四类机构,分析提高科技创新效率的实现路径,可以通过重点突破模式和渐进突破模式来实现整体效率的提高。  相似文献

国内关于图书馆焦虑的研究已经开展多年,并取得一定的研究成果。以我国图书馆焦虑的研究文献的关键词为统计对象,基于共词分析,利用聚类方法和战略坐标图分析我国在该领域的研究现状。结果表明,目前该领域的研究集中于读者自身、图书馆环境和图书馆员三大因素的研究,从理论上研究图书馆焦虑起因的关注度在降低,图书馆焦虑缓解措施的可行性和有效性研究比较缺乏。最后给出了该领域在下一步研究中的可能方向,供研究人员参考。  相似文献

当今世界正处于“百年未有之大变局”中。这是中国共产党对于世界新的时代特征的全新、科学和准确的研判。“百年未有之大变局”这一重大论断,具有深厚的马克思主义哲学的本体论基础、认识论基础、矛盾论基础和历史观基础。作为科学世界观与方法论,马克思主义哲学的辩证唯物主义和历史唯物主义为我们深刻认识和精准把握“百年未有之大变局”的深层本质和哲学依据提供了重要的认知性引导、方法论基础和实践智慧支撑。  相似文献
