Today's turbulent business and social environment often compels organizations to adopt internal programs that will help them cope with complexity. One organizational sector in which this is particularly true is the health care industry, as managed care programs and competitive forces have changed the way hospitals and clinics operate. This study looks at a specific organizational program designed to cope with these industry changes and considers the impact of the program on the nurses involved. Drawing on theory and research on role development and strategic ambiguity, this case analysis looks at a hospital system in which the nursing role of “care coordinator”; was defined in a strategically ambiguous way. After analyzing interviews with 19 care coordinators, conclusions are drawn regarding affective reactions to strategic role ambiguity, behavioral adaptation to strategic role ambiguity, and the importance of conceptualizing role ambiguity as a systemic process. 相似文献

运动对糖尿病大鼠ASP影响的研究 总被引:1,自引:0,他引:1
研究运动对链脲佐菌素所致糖尿病大鼠ASP的影响。选用雄性SD大鼠,随机分为4组(每组10只),即:正常对照组,正常运动组,糖尿病模型组,糖尿病模型+运动组。运动组进行10周的游泳训练。结果表明:1)糖尿病模型组与正常对照组大鼠相比,血浆ASP浓度、血糖、TG、和LDL明显升高,血清FFA有升高趋势,血清胰岛素和ISI明显降低;2)糖尿病模型+运动组较其非运动组血浆ASP浓度、血糖、TG、TC、FFA和LDL明显降低,血清胰岛素和HDL含量明显升高。提示:糖尿病机体血浆ASP浓度升高,伴随着其活性下降,使得FFA和富舍TG的脂蛋白消除障碍,长期中等负荷运动可以降低血浆中ASP浓度,增加其活性,进而降低FFA和TG水平,升高HDL,改善糖尿病机体的脂质代谢,预防其慢性并发症的发生。 相似文献

Christian education served as a tool of White supremacy that played a central role in the devastation of millions of human lives throughout the colonial era of Western expansion. An adequate account of how Christian education paired with colonial imperatives helps to identify where the legacy of White supremacy and imperial domination lives on in contemporary practices of Christian faith formation and religious education. While any educational venture requires authority and is an act of power, humility is an essential partnering virtue for Christian educators who do not wish to replicate this history of domination. 相似文献

Students with disabilities present a unique instructional design challenge. These students often have qualitatively different ways of processing information, meaning that standard instructional approaches may not be effective. In this study I present a case study of a student with a mathematical learning disability for whom standard instruction on fractions had been ineffective. With regard to theory, I draw on Lev Vygotsky’s framing of disability and then use Anna Sfard’s conceptualization of mathematics as a discourse to design a fraction re-mediation that provided a bridge from the student’s discourse to the canonical mathematics discourse. This bridging discourse was used in 5 videotaped re-mediation sessions with the case study student. A fine-grained analysis of the re-mediation sessions traced the ways in which the student’s discourse shifted over time, which enabled her to solve problems she had previously been unable to solve. This study provides a proof of concept for reconceptualizing remediation and illustrates the potential utility of a bridging discourse to help students who have a history of failure gain access to the canonical mathematics discourse and content. 相似文献

This article traces the experiences of two veteran elementary school teachers in the urban Southwest, who are positioned by district and state policy ‘texts’ as insubordinate and failing, and who employ critical literacy practices to reconstruct and redesign these texts as they seek to create more equitable and humane conditions in schools. Stemming from a larger phenomenological study, this article explores how teachers in a ‘failing’ elementary school in the Southwestern US understand and negotiate district, state, and federal policies and examines how these policies shape and inform their identities as professionals. This research has important implications concerning the potential of critical literacy as a mode of resistance, the promise inherent in school/university partnerships for promoting change, and the ways in which the practice of deconstructing/reconstructing dehumanizing texts can foster a re-professionalization of teaching. 相似文献

Research Findings: The aim of this study was to provide an initial investigation into the psychometric properties of the Problems in Classroom Engagement Scale (PCES). The PCES was designed and tested for district-wide use as part of the report card system for a large urban school district. The PCES was administered to all 1st-, 2nd-, and 3rd-grade students in the district. Factor analytic examination revealed a bifactor structure as the best fit to the data. The bifactor structure reflected a general factor of Problems in Behavioral Engagement and two group factors: Problems in Social Engagement and Problems in Academic Engagement. These factors were found to be reliable within and across grades and demonstrated convergent and divergent relations with academic and behavioral outcomes. Practice or Policy: Findings provide initial evidence to support the routine use of the PCES in a large urban setting. The use of the PCES can help in fostering district-wide attention to students’ early difficulties with behavioral, social, and academic engagement. 相似文献

Teens' own thoughts on fostering safe sexual practice are important perspectives in promoting adolescent sexual health yet are relatively absent in the literature. This focus group study explored teens' perceptions about the supports and challenges that exist as teens strive to engage in healthy sexual practices. Seventy-five teens participated in 11 focus groups using a semi-structured interview guide. School-based health centers provided the setting and facilitated sample recruitment. Focus groups were audiorecorded and transcribed verbatim. Data were analyzed using the focus group guide as a template and typologies, or clusters of concepts, were extracted to establish teen perceptions of the factors that support and challenge their ability to engage in safe sexual practices. The socio-ecological model provided the framework to identify these factors within the individual, family/parent, relational (peer/partner), community, or societal spheres of influence. Results discussed the importance of parents, the value of confidentiality, respect for teen decision-making, relationships skills, developmental aspects of the adolescent years, and social interpretations of gender. These findings revealed important considerations as adults develop policies, messages, and programs designed to promote safe sexual behavior in teens. 相似文献
