This study examined factors that might affect researchers' willingness to collaborate with a specific researcher and the priorities given to those factors. In addition, it investigated how researchers determined the ownership of collaborative project data and how they determined the order of authorship on collaborative publications in condensed matter physics. In general, researchers rated their intrinsic motivations the highest, such as the quality of ideas a potential collaborator might have and their satisfaction with a past collaboration, followed by their extrinsic motivations, such as the complementary knowledge, skills, or resources the collaborator could provide. In addition, researchers who had a greater number of collaborative projects and researchers who had served as a project PI or co-PI valued the deep-level, personality-related characteristics of a collaborator higher than did those who had not. Younger researchers were more risk averse and more concerned with a collaborator's reputation and the possible cost of a collaboration decision. Additionally, younger researchers indicated more often than older researchers that they did not know whether their project teams followed any rules or norms or engaged in negotiation to determine the order of authorship on collaborative publications.  相似文献

Using data from a representative panel of 1,000 Minnesota youth, this paper explores "helpfulness" in 2 spheres of adolescents' lives: the home and paid work settings. We examine the social structural conditions under which helpful behaviors are elicited, the interrelations of helpfulness and competence across 2 years of middle adolescence, and whether social circumstances moderate the effects of helpfulness on competence. Both boys' and girls' helpfulness in the home is responsive to family need. Furthermore, helpfulness at work and girls' competence are reciprocally related. We find evidence that the effects of helpfulness depend on the helper's motivations and the act's meaning, as shaped by the social context. Girls' competence is diminished by helpfulness in the home under conditions of poor father-daughter relationships and coercive maternal control.  相似文献

This paper explores the beliefs about self-as-teacher, learning and teaching of preservice elementary teachers during a three-year undergraduate programme. Using a qualitative grounded theory analysis, the study examined the initial beliefs or personal theories of 27 preservice teachers during their first Semester. Longitudinal data were gathered from 7 of these students over the three-year duration of their teacher education programme through iterative interviews and reflective journal analysis. The findings demonstrate expansion in preservice teachers’ understandings of the teacher’s role, the value of reflective practice, the differential needs of learners and approaches to pedagogy. Findings point to lacunae in preservice teachers’ capacity for critical reflective practice and demonstrate how classroom management concerns can cause preservice teachers to adopt more cautious and traditional pedagogical approaches, despite their espoused commitment to child-centred principles.  相似文献

The purpose of this study is to examine how children's starting level and development of social competence (i.e., task orientation and peer sociability) during kindergarten and first grade predict gifted program enrollment by third grade, even after considering children's cognitive ability. A second purpose is to examine the extent to which the relationship between children's social competence and gifted program enrollment differs depending on children's socioeconomic status (SES), ethnicity, and gender. Latent growth curve analyses conducted on 347 children revealed that students enrolled in gifted programming were not only those high in cognitive ability, but also those showing early task orientation. Neither peer sociability's initial status nor growth was a significant predictor of gifted enrollment. Multigroup comparisons demonstrated different predictive paths for higher versus lower SES groups. Implications are discussed including important questions raised by this study and the need for teacher training in the identification of giftedness. © 2008 Wiley Periodicals, Inc.  相似文献

Given the significant negative impacts of peer victimization on youth development, studies have sought to understand what buffers against these consequences. To that end, the present study examined whether teacher attachment and perceptions of school safety moderated the associations between different forms of victimization and school absences over the course of an academic year among a sample of 272 high school students. Findings indicated that teacher attachment moderated the associations between relational and cyber victimization and absences, while perceived school safety moderated associations between relational victimization and absences. However, findings pertaining to cyber victimization were not as anticipated. Implications for prevention and intervention efforts in high schools are discussed.  相似文献

In light of growing concerns in the public and recent mandates from business program accrediting bodies and curricular task forces, the importance of teaching ethical topics in information systems programs is discussed. Innovative strategies used for teaching the application of ethical criteria to common situations are reviewed. Results of a survey of information systems faculty members in the US are presented and are compared to previous studies that related primarily to computer science and software engineering programs. Insight is provided into the topics, techniques, degree of coverage, and assessment techniques currently used when teaching ethics in computing-related programs. Key concerns and future work is also outlined.  相似文献

The success of a traditional residential education program is typically measured by numbers of students who attend and how much they liked it. Kathleen Kerr and James Tweedy offer a peer‐reviewed curricular approach that determines success by how much students learn.  相似文献
