Although there is some general agreement that increasing levels of collaboration amongst academics produce research papers that receive more citations, and that larger numbers of citations often imply higher quality, the issue of collaboration and its effect upon research output remains a controversial area with a wide range of views of what role collaboration plays and its general implications for quality. This paper re-examines the process of collaboration within research networks. It considers the role of collaboration and its effect on quality by studying the relationship between the level of interaction within research networks (collaboration) and the extent of variability of quality within those research networks. Twenty-two scientific networks from Austria are examined. The findings of the analysis are that increasing levels of collaboration are strongly associated with lower levels of variability of quality within each network. The conclusion is therefore drawn that collaboration at the level of the research network acts upon research quality qua peer review and that this peer review effect is inherent throughout the research process.  相似文献

Collaborations in funded teams are essential for understanding funded research and funding policies, although of high interest, are still not fully understood. This study aims to investigate directed collaboration patterns from the perspective of the knowledge flow, which is measured based on the academic age. To this end, we proposed a project-based team identification approach, which gives particular attention to funded teams. The method is applicable to other funding systems. Based on identified scientific teams, we detected recurring and significant subgraph patterns, known as network motifs, and under-represented patterns, known as anti-motifs. We found commonly occurred motifs and anti-motifs are remarkably characterized by different structures matching certain functions in knowledge exchanges. Collaboration patterns represented by motifs favor hierarchical structures, supporting intensive interactions across academic generations. Anti-motifs are more likely to show chain-like structures, hindering potentially various knowledge activities, and are thus seldom found in real collaboration networks. These findings provide new insights into the understanding of funded collaborations and also the funding system. Meanwhile, our findings are helpful for researchers, the public and policymakers to gain knowledge on research(ers) evolution, particularly in terms of primordial collaboration patterns.  相似文献

Biomedical researchers often work with massive, detailed and heterogeneous datasets. These datasets raise new challenges of information organization and management for scientific interpretation, as they demand much of the researchers’ time and attention. The current study investigated the nature of the problems that researchers face when dealing with such data. Four major problems identified with existing biomedical scientific information management methods were related to data organization, data sharing, collaboration, and publications. Therefore, there is a compelling need to develop an efficient and user-friendly information management system to handle the biomedical research data. This study evaluated the implementation of an information management system, which was introduced as part of the collaborative research to increase scientific productivity in a research laboratory. Laboratory members seemed to exhibit frustration during the implementation process. However, empirical findings revealed that they gained new knowledge and completed specified tasks while working together with the new system. Hence, researchers are urged to persist and persevere when dealing with any new technology, including an information management system in a research laboratory environment.  相似文献

校企合作对于高等职业技术教育是不可或缺的基础条件,是培养高职实用人才的有效途径。校企合作^[1]的形式大体分为“企业配合”、“校企联合培养^[2]”和“校企实体合作型”三种模式。校企合作中学校应当注重培养学生的综合素质及实践动手能力,企业应当在师资和实训基地建设方面加强与学校的合作实现互利双赢。  相似文献

The twenty-first century economy often requires the innovative production of conceptual and physical artifacts. These innovations frequently are developed collaboratively within communities of workers. Previous theories about the nature of work and learning within communities have emphasized shared meaning or shared practice, but now shared innovation is required. In this paper, I describe the development of a model for conceptualizing and studying shared innovation within communities. This model was created from merging elements of social learning and creativity/innovation theories. I explain that at an intersection of these two domains is a unique kind of social structure, called a Community of Innovation, or COI. I conclude by describing the characteristics of a COI and its implications for design and research.

This case study examines how differing views on the teacher's role in school reform affected the work of a school–university partnership. The school district and the university had a history of partnerships and shared common general goals. Yet, as the partnership progressed, conflicting perspectives about teaching and the purpose of professional development became evident and created dilemmas that influenced the nature of the work. We provide background information about each partner, describe the two views, and examine how the differing perspectives influenced the goals and activities of the partnership. This study highlights the complex issues embedded in school–university collaboration.  相似文献

The aim of this article is to extend the scope of the models of teacher change to an interactionist view which co-ordinates sociocultural and constructivist perspectives. Accordingly our focus will be on the cultural and situational factors and processes of social interaction, as well as on the development on an individual level. First we study how roles, statuses, expectations as well as social and socio-mathematical norms were formed in the group of four student teachers, when they were co-planning, teaching and assessing mathematics lessons during their teaching practice. Finally, we attempt to construct a collaborative, interactionist model of teacher change integrating sociocultural and constructivist perspectives.  相似文献
