Few women breastfeed for 6 months or longer, and many who stop breastfeeding do so in the early postpartum period. To increase the number of breastfeeding mothers, health-care providers need to identify women at greatest risk for early breastfeeding attrition. This integrative review describes instruments used to assess breastfeeding in the early postpartum period and reports the results of studies using these tools. The instruments are then evaluated for similarities in variables and usefulness for clinical practice.  相似文献

Abstract

This paper examines how post-secondary agricultural education and training (AET) in sub-Saharan Africa can contribute to agricultural development by strengthening the capacity to innovate—to introduce new products and processes that are socially or economically relevant to smallholder farmers and other agents. Using the AET system in Mozambique as a case study, this paper examines the role of AET within the context of an agricultural innovation system. This innovation systems perspective offers an analytical framework to examine technological change in agriculture as a complex process of interactions among diverse actors who generate, exchange, and use knowledge, conditioned by complex social and economic institutions. The paper argues that while AET is conventionally viewed as key to the development of human capital, it also has a vital role to play in building the capacity of organizations and individuals to transmit and adapt information, products and processes, and new organizational cultures and behaviors. The paper emphasizes the importance of improving AET systems by strengthening the capabilities of organizations and professionals; changing organizational cultures, behaviors, and incentives; and building innovation networks and linkages. The paper offers several recommendations to enhance the effectiveness of AET for agricultural innovation and development. Key reforms include aligning the mandates of AET organizations with national development aspirations; inducing change in the cultures of AET organizations through the introduction of educational programs and linkages beyond the AET system; and enhancing innovative individual and organizational capacity by improving incentives to forge stronger links between AET and other stakeholders.  相似文献

This study is an examination of the state of the liberal arts curriculum in community colleges in three geographic regions of the United States. From a constructivist paradigm and using globalization theory as a theoretical framework, this multiple case study examined faculty work life and administrative processes related to curriculum change in merged community and technical colleges. Through an examination of research on globalization, mergers, and trends in the general education and liberal arts curriculum, a gap in the literature emerged in the studies of community college curriculums after merger. This study considers whether the focus on workforce development and decrease in the transfer mission has diminished the liberal arts courses in the college curriculum. Research on liberal arts courses identified them as courses that emphasize higher order thinking and the development of intellectual skills needed to engage in a democratic society. If students are not exposed to these skills, it may have a detrimental effect on a democratic society. Study findings suggested that the English and communication curriculums are narrowing and the mission is more toward workforce skill preparation. Also, the changing demographics of today[#x02019]s community college students, as well as the ongoing budget constraints, create challenges and frustrations for faculty members.  相似文献

The impacts of war and displacement on executive function (EF)—what we might call the cognitive signatures of minds under siege—are little known. We surveyed a gender-balanced sample of 12- to 18-year-old Syrian refugees (n = 240) and Jordanian non-refugees (n = 210) living in Jordan. We examined the relative contributions of poverty, trauma exposure, posttraumatic stress, and insecurity to variance in inhibitory control and working memory. We observed associations between poverty and WM, suggesting that, even in populations exposed to substantial violence and fear, poverty is a specific pathway to WM deficit. We did not, however, find associations between EFs and exposures to trauma. Careful distinction between childhood adversities may illuminate which neurocognitive pathways matter for measures of cognitive function.  相似文献
