There is scanty information on the role of genetic factors, especially those relating to haptoglobin (Hp) phenotypes in the
expression of complications among diabetes mellitus patients in Ghana. In this study, we investigated whether there is any
association between Hp phenotypes and diabetic complications and to determine if association of the Hp phenotypes with diabetic
complications in Ghanaian diabetics differ from those in Caucasians. A total of 398 participants were randomly recruited into
the study. These comprised diabetic patients numbering 290 attending a diabetes Clinic in Ghana and 108 non-diabetic controls
from the same community. Analyses of the results indicate that most of the diabetics with complications were of the Hp 2–2
(35%) and Hp 2–1 (23.9%) phenotypes. Fewer diabetics were found to be of the Hp 2–1 M phenotype. The controls were mostly
of Hp 1–1 and Hp 2–1 M phenotypes. The odds ratio of having complications in a diabetic with an Hp 2–2 phenotype was 18.27
times greater than that for Hp 0–0. Hp 2–2 phenotype with its poor antioxidant activity may therefore be a useful predictor
for the propensity of an individual to develop diabetes complications. 相似文献

This study examined social influences on 3‐year‐old children's decisions to help an experimenter gain another person's attention (N = 32). Children were slower to help the experimenter when the target had previously expressed disinterest in attending to her. Shy children were less likely to support the experimenter's attempts to communicate with the target; however, this association was not influenced by children's knowledge of the target's disinterest, and there was no relation between shyness and children's support for a separate physical goal. Therefore, young children's decisions to act helpfully incorporate consideration for others beyond a focal person with an unmet need, and they are further constrained by children's own comfort with the actions required to help. 相似文献

This article discusses the use of digital storytelling, a pedagogical tool, to enhance student learning and meaning-making. During the process of creating and sharing their digital stories, students engaged in self-reflexivity and demonstrated the ability to apply theories of student development to their personal experiences. Findings have implications for educators concerned with assisting students in making meaning of abstract theories and in connecting theory to practice. 相似文献

Power,agency and middle leadership in English primary schools 总被引:1,自引:0,他引:1
English primary schools are considered quasi‐collegial institutions within which staff communicate regularly and openly. The activities of staff, however, are bound by institutional norms and conditions and by societal expectations. Wider agendas of governmental control over the curriculum and external controls to ensure accountability and learning standards have influenced the development and purposes of middle leaders’ roles. This is a conceptual paper that explores issues around the agency of primary school middle leaders within a wider context of the political and educational agenda. Through a reconsideration of research conducted by one of the authors since the inception of the notion of ‘subject leaders’, we exemplify ways in which primary school middle leaders’ attitudes have developed and changed over the past 15 years. In this paper we identify attitudes to leadership, the influence of distributed leadership on primary school role‐holders and possible ways forward for middle leaders. 相似文献

The purpose of this study was to investigate high school teachers’ beliefs about inquiry instruction and determine how their beliefs influenced their use of inquiry after a professional development program. Thirty-six high school science teachers participated in this study. The professional development program consisted of a 2-week summer institute as well as academic year support. The summer program included discipline-specific content lessons that utilized inquiry-based instruction, pedagogical practice involving the use of a summer high school enrichment program, and reflection on this practice-teaching in content area groups. Both in-depth qualitative interview and written reflection data were collected as well as data from the teachers’ classroom implementation of inquiry. Based on the analysis of the teachers’ interviews and classroom enactments, the teachers were placed into four enactment categories: Integrated, Emerging, Laboratory-based, and Activity-focused. We used Windschitl’s (Rev Educ Res 72(2):131–175, 2002) four constructivist dilemmas as a framework to understand the teachers’ enactments. We describe the teachers’ beliefs and practices in each enactment category as well as the components of the professional development model that were important to making changes in the teachers’ practices. In the conclusion, we connect the enactment levels to the professional development experience and suggest future directions for professional developers to move teachers toward more integrated inquiry practices. 相似文献

This study examined the demographic factors that predict intention to integrate technology into instruction by community college adjunct faculty. Regression model findings indicated that the demographic characteristics of years of teaching experience, teaching discipline, hours of preparation time, and years of experience using computers were predictors of intention to integrate technology. Other literature-based characteristics such as age, gender, and participation in professional development activities, although not noted predictors in the current study, still warrant further examination to provide additional insight into their potential ability to predict technology use by community college adjunct faculty. 相似文献

The Computer Based Collaborative Group Work (CBCGW) Project is an institutional Teaching and Learning Technology Programme (TLTP) Project based in the Department of Educational Studies. The Project aims to support those within and beyond institutional boundaries in the exploration and uptake of collaborative work in a networked environment. This paper reviews examples of current practices in online professional development from around the world and considers some of the issues for providers of academic support. This will in turn be used to contextualize the response to these needs being developed by the Project. 相似文献
