The growing complexity of scientific challenges demands increasingly intense research collaboration, both domestic and international. The resulting trend affects not only the modes of producing new knowledge, but also the way it is disseminated within scientific communities. This paper analyses the relationship between the “degree of internationalization” of a country’s scientific production and that of the relevant citing publications. The empirical analysis is based on 2010-2012 Italian publications. Findings show: i) the probability of being cited increases with the degree of internationalization of the research team; ii) totally domestic research teams tend to cite to a greater extent totally domestic publications; iii) vice versa, publications resulting from international collaborations tend to be more cited by totally foreign publications rather than by publications including domestic authors. These results emerge both at overall and at discipline level. Findings might inform research policies geared towards internationalization. 相似文献

This paper aims to analyse the practice of knowledge integration (KI) in Collaborative New Product Development (Co-NPD) projects involving multiple partners in an aerospace network. On the basis of a pragmatic approach, a multiple-case study is developed focusing on two Italian aerospace companies involved in a research project aimed to define methodologies and technologies for knowledge collaboration in NPD. Data are gathered with a triangulation technique merging official documents and open-ended and closed-ended interviews administered in the companies’ sites and involving managers, engineers and employees. The paper proposes a systematic treatment of the KI practice describing the types of knowledge, strategies, barriers and intellectual property policies for KI at inter-organizational level. The findings provide insights to address NPD models for aerospace networks where the complexity and value of codified knowledge coming from external sources requires adequate treatments and security standards. 相似文献

OBJECTIVES: To describe the characteristics and repertoires of community practitioners serving families involved in child physical abuse that may inform training and treatment dissemination efforts. The aims are to: (a) describe the background characteristics of these clinicians; (b) document their most common intervention techniques; (c) examine clinicians' attitudes toward manualized treatment; and (d) understand the organizational climate of community agencies. METHOD: Practitioners from nine different agencies who have worked with cases in which there was child physical abuse (n=77) completed focus group discussions and three self-report questionnaires. Qualitative and quantitative analyses were conducted in tandem. RESULTS: Practitioners reported that they most often focused on family issues and employed family therapy techniques. Although treatment manuals were important, it was difficult to determine how practitioners used or would use these materials with families. An almost equal number of concerns and benefits were raised regarding using manuals in treatment. There was moderate agreement in how practitioners perceived their work environments. Age and attainment of a graduate degree were positively related to greater caring and job satisfaction, respectively, while length of time at a given agency was positively related to greater reports of emotional exhaustion on a measure of organizational climate. CONCLUSIONS: Given the promising benefits of evidence-based treatments for child abuse, it is important that researchers begin to form partnerships with community agencies that will lead to the dissemination and evaluation of effective treatment strategies. 相似文献

Student engagement in the design and implementation of inquiries is an effective way for them to learn about the inquiry process and the domain being studied. However, inquiry learning in geography can be challenging for teachers and students due to the complexity of scientific inquiry and the diversity of pupils' and teachers' knowledge and abilities. To address this, the Personal Inquiry project has designed a tool kit that includes nQuire, a Web-based tool to support students through the inquiry process. Here, we identify when, across five lessons comprising an inquiry into microclimates, nQuire was used by a teacher and a case study group of her 12 to 13-year-old students, and the ways in which they adopted nQuire as a tool to facilitate the creation of a coherent and cumulative inquiry learning experience over time. We found that students' use of nQuire supported them in capturing and representing their evolving understanding of inquiry, in defining and supporting their progression through the process of inquiry and in resourcing their cognitive engagement in data interpretation and representation. nQuire supported the students in accumulating and integrating new understandings across contexts and over time. In this way, nQuire successfully resourced and supported the students' learning journeys or trajectories. We conclude that nQuire can be an effective tool for supporting teachers' and students' understanding of the nature of inquiry and how to design and implement inquiries of their own. 相似文献

This article which is largely conceptual in nature, explores the possibilities provided by embracing complexity thinking that are attentive to, but not confined by, externally imposed curriculum mandates while simultaneously honoring the interests and needs of individual students and the classroom collective. From this perspective, the ideas of negotiating authority, adopting a holistic view, engaging in participatory democratic practices, and using a project-based approach to learning are examined. In doing so, the concept of ‘activity frames’ is introduced and developed as a useful way of responding to curriculum mandates while being responsive to and respectful of individual and collective student learning agendas. 相似文献
