Previous research has shown that clarity of roles and responsibilities (CRR) influences the performance of individual organizations as well as inter-organizational efforts. In the context of cross-boundary information sharing (CBIS), CRR has been found to enable other important determinants of success, such as building trust among members, increasing their willingness to participate, and mitigating some of their concerns about security, among others. However, few studies have attempted to understand the determinants of CRR in government CBIS initiatives. Sayogo, Gil-Garcia, and Cronemberger's (2016) analysis of results of a national survey identified three significant determinants of CRR in CBIS, (1) the extent participants use boundary objects, (2) participant skills in terms of collaboration, coordination, and communication, and (3) the diversity of the participating organizations and their goals. Seeking to expand on their findings in terms of new understanding about the influence of significant determinants of CRR in CBIS, this study draws on findings from eight U.S. state and local government public health and criminal justice CBIS cases. This study contributes to existing knowledge about CBIS in the public sector by characterizing the determinants and providing new understanding of the nature of the influence of the determinants of CRR on CBIS. In particular, it shows how the extent of boundary object use, collaboration, and the diversity of participants affect CBIS initiatives in different contexts. In practical terms, creating new understanding of the determinants of CRR has value for public managers and their leadership as they must increasingly collaborate and share information across the boundaries of organizations in the process solving increasingly complex public problems. 相似文献

Socially similar social media users can be defined as users whose frequently visited locations in their social media histories are similar. Discovering socially similar social media users is important for several applications, such as, community detection, friendship analysis, location recommendation, urban planning, and anomaly user and behavior detection. Discovering socially similar users is challenging due to dataset size and dimensions, spam behaviors of social media users, spatial and temporal aspects of social media datasets, and location sparseness in social media datasets. In the literature, several studies are conducted to discover similar social media users out of social media datasets using spatial and temporal information. However, most of these studies rely on trajectory pattern mining methods or take into account semantic information of social media datasets. Limited number of studies focus on discovering similar users based on their social media location histories. In this study, to discover socially similar users, frequently visited or socially important locations of social media users are taken into account instead of all locations that users visited. A new interest measure, which is based on Levenshtein distance, was proposed to quantify user similarity based on their socially important locations and two algorithms were developed using the proposed method and interest measure. The algorithms were experimentally evaluated on a real-life Twitter dataset. The results show that the proposed algorithms could successfully discover similar social media users based on their socially important locations. 相似文献

This study investigated the metaphorical images that prospective teachers in Turkey formulated to describe learners. Participants (N = 2847) completed the prompt “A student is like … because …” to indicate their conceptualizations of learner. Data were analyzed both qualitatively and quantitatively. Altogether 98 well-articulated metaphorical images were identified and 12 conceptual themes were developed. Significant associations were detected between teacher trainees' gender, programme type and status in programme, and the 12 conceptual themes. Metaphors provided a cognitive lens into prospective teachers' thinking and cognition. Implications for teacher education and further research are discussed. 相似文献

This article reviews the pertinent research literature on metaphors in teaching and teacher education. The main purpose is to explore these metaphors as evidences of prospective and practicing teachers' reasoning about teaching, learning, and schooling. The current review is organized around the major functions of metaphor in education. In this way, it is intended to contribute to the existing scholarly research in the field of teaching and teacher education stemming largely from metaphor analysis. The present essay discusses 10 distinct functions of metaphor in education and provides illustrative studies for each function. It strongly argues for the inclusion of various educational metaphors in teacher education programs because of their functional benefits. 相似文献

Exploring Students’ Ideas About Risks and Benefits of Nuclear Power Using Risk Perception Theories 总被引：1，自引：0，他引：1

Due to increased energy demand, Turkey is continuing to explore the possibilities of introducing nuclear power. Gaining acceptance from local populations, however, may be problematic because nuclear power has a negative image and risk perceptions are complicated by a range of psychological and cultural factors. In this study, we explore the views about nuclear power of school students from three locations in Turkey, two of which have been proposed as sites suitable for nuclear power plants. About half of the student cohort believed that nuclear power can supply continuous and sufficient electricity, but approximately three quarters thought that nuclear power stations could harm organisms, including humans, living nearby. Rather few students realized that adoption of nuclear power would help to reduce global warming and thereby limit climate change; indeed, three quarters thought that nuclear power would make global warming worse. There was a tendency for more students from the location most likely to have a nuclear power plant to believe negative characteristics of nuclear power, and for fewer students to believe positive characteristics. Exploration of the possible nuclear power programmes by Turkey offers an educational opportunity to understand the risk perceptions of students that affect their decision-making processes. 相似文献

For science teachers using the discourse of socioscientific issues (SSI), it is important to make a decision as to whether when and how to disclose their own positions. The existing limited literature shows that science teachers prefer one of four roles during SSI discourse: sticker to facts, imposer, democracy advocator, and committed impartialist. The purpose of the present research is to understand the nature of preservice science teachers’ (PST) beliefs underlying such selection. Based on existing literature, we developed a teacher’s belief questionnaire including vignettes representing four teacher’s roles in discussion of genetically modified (GM) foods. Three hundred twenty-four (324) PSTs from a Turkish context experiencing SSI-based reforms completed these questionnaires, selected one of the teacher’s roles, and justified their selection by writing reasons. Content analysis procedures were used in data analysis of this qualitative study. The results show that most PSTs selected dialogical roles (democracy advocators and committed impartialists). Looking at their beliefs, epistemologies and teaching goals work together in PSTs’ selection of their preferred role. In addition, we argue that there is no desired alignment between teachers’ existing beliefs and expectations of SSI reforms. We conclude by indicating certain implications that may enhance such alignment. 相似文献

Currently, it is strongly suggested that our thought processes are largely metaphorical in nature. Indeed, the metaphors we use not only represent the way we perceive the world and reality but also shape our professional ideas, attitudes, and practices. This study employs metaphor as a means of research to provide insights into the images prospective classroom teachers have of themselves as future teachers (i.e., professional self-images), their elementary teachers (i.e., former classroom teachers), and their cooperating teachers (i.e., supervisors of student teaching practices). Data for this study were gathered through the administration of a Likert-style questionnaire consisting of 20 metaphorical images of “classroom teacher” to 363 exit level elementary teacher education students enrolled in the Faculty of Education of Selcuk University in Turkey during the 2002–2003 academic year. Results indicate that the teacher candidates in this study appear to be less teacher-centered and more student-centered than their both elementary and cooperating teachers. Also, female teacher candidates appear to be less teacher-centered and more student-centered than their male peers. Implications for preservice teacher education and further research are discussed. 相似文献

This paper discusses the organization of adult education in Turkey. From a historical perspective, it examines the development, organization and problems of post‐school adult education. It shows these to be related to the politics and position of Turkish society in the Middle East and to the high degree of centralization of educational decision making in Turkey. The paper argues a case for the decentralization of adult education services for better training of adult educators and better delivery of adult educational provisions. 相似文献
