Despite the increasing interest taken in knowledge management (KM) by a wide range of practitioners as well as the library and information science (LIS) community, knowledge management is not systematically applied in libraries. Due to the complexity of knowledge, as well as the multifaceted nature of knowledge management, there is no consensus among LIS professionals regarding its relation to information management. In this context, the current study aims at exploring how library employees perceive knowledge management, as well as which KM tools and techniques are adopted by academic libraries. The results indicate that although practitioners are aware of knowledge management and appreciative of its benefits not only for library performance but also for LIS professionals' future career options, there is a lack of clarity on fundamental KM issues. Finally, academic libraries take steps towards capturing the knowledge of their users and internal explicit knowledge; however, social practices such as communities of practice, which facilitate tacit knowledge and expertise sharing, are not adopted. 相似文献

According to the dual systems model of adolescent risk taking, sensation seeking and impulse control follow different developmental trajectories across adolescence and are governed by two different brain systems. The authors tested whether different underlying processes also drive age differences in reward approach and cost avoidance. Using a modified Iowa Gambling Task in a multinational, cross‐sectional sample of 3,234 adolescents (ages 9–17; M = 12.87, SD = 2.36), pubertal maturation, but not age, predicted reward approach, mediated through higher sensation seeking. In contrast, age, but not pubertal maturation, predicted increased cost avoidance, mediated through greater impulse control. These findings add to evidence that adolescent behavior is best understood as the product of two interacting, but independently developing, brain systems. 相似文献

In this paper, the main points of Lamarck’s and Darwin’s theoretical conceptual schemes about evolution are compared to those
derived from 15 years old students’ explanations of evolutionary episodes. We suggest that secondary students’ preconceptions
should not be characterized as “Lamarckian”, because they are essentially different from the ideas that Lamarck himself possessed.
Most students in our research believed that needs directly impose changes on animal bodies in order to survive in a given
environment and accepted the possibility of extinction whereas Lamarck believed that it was the effect of use or disuse that
would produce changes on body structures and that species would transform but would not die out. We conclude that the relationship
between secondary students’ ideas and historical views on evolution should be treated more skeptically, given the differences
in the historical, social and cultural contexts, and that instruction should focus on students’ ideas of need-driven evolution
as well as on the role of chance in the evolutionary process. 相似文献

This work explores the relationship between product innovation and the decision to invest in fixed capital assets among a sample of SMEs in six European Union countries located in both peripheral and more central areas. We find that the presence of product innovation reduces the probability to invest. A firm’s size exerts a direct, inverted U-shape effect on the probability to invest and an indirect effect through the linear effect of size on the probability to innovate. The gap in the probability to invest between innovative and non-innovative firms increases with size. 相似文献

Nowadays, it is commonly accepted in both researchers' and practitioners' communities that many disciplines and practices of the knowledge management (KM) field are also relevant and applicable to the knowledge-based development. This is reflected by the fact that the theme of knowledge cities (KCs) is now a ‘hot’ topic of interest and discussion. However, as it also happened with the early stages of evolution of KM, there is neither a coherent framework nor a unified methodology for the design and implementation of successful KCs. The real success of KCs is under investigation in the research community. In this direction, the authors propose a set of hypotheses for the design, development and operation of successful KCs. Then, based on an empirical evaluation of several case studies that have been successfully put in real practice they discuss the support of each case to these hypotheses. The key findings are expressed as a framework for building successful KCs. 相似文献

Research has shown that children usually provide teleological explanations for the features of organisms from a very early age (3?C4?years old). However, it is not clear if teleology is applied selectively for organisms, or if it is generally applied to other objects as well (artifacts and non-living natural objects). The present study examined whether 7?C8?year old students provided teleological explanations for particular organisms, artifacts and natural objects. We investigated whether children's familiarity with these objects influenced the types of explanations they gave. Finally, we also investigated correlations between 'teleology' and 'usefulness' in children's explanations. The results indicate that 7?C8?year olds are able to distinguish between living and non-living entities, as well as that they provide teleological explanations mostly for organisms and artifacts. This may have important implications for biological education, since teleological explanations in classrooms are likely to pose important conceptual obstacles to the development of a scientific understanding of evolution. 相似文献
