Agent-based modeling of knowledge dynamics     

Mark E?NissenEmail author  Raymond E?Levitt 《知识管理研究与实践》2004,2(3):169-183

Knowledge is distributed unevenly through most enterprises. Hence, flows of knowledge (e.g., across time, people, locations, organizations) are critical to organizational efficacy and performance under a knowledge-based view of the firm. However, supported principally by narrative textual theory in the emerging knowledge management (KM) field, the researcher has difficulty describing how different kinds of knowledge will flow through various parts of an organization. This causes difficulty also for predicting the effects of alternate approaches to dispersing knowledge that ‘clumps’ in various areas. This problem is also manifest for the KM professional, who lacks clear theory or tools to anticipate how any particular information technology or other managerial intervention may enhance or impede specific knowledge flows in the enterprise. In this expository article, we build upon a steady stream of research in computational organization theory to develop agent-based models of knowledge dynamics. This work draws from emerging theory for multidimensional representation of the knowledge-flow phenomenon, which enables the dynamics of enterprise knowledge flows to be formalized and emulated through computational models. This approach provides the means for knowledge-flow processes to be visualized and analyzed in new ways. Computational experimentation enables the performance of many alternate process designs and technological interventions to be compared through examination of dynamic models, before committing to a specific approach in practice. We illustrate this research method and modeling environment through semi-formal representation and agent-based emulation of several knowledge-flow processes from the domain of software development. We also outline key directions for the new kinds of KM research and practice elucidated by this work.  相似文献   

Perceptions of declining classmate and teacher support following the transition to high school: Potential correlates of increasing student mental health difficulties     

David J. De Wit  Kim Karioja  B. J. Rye  Martin Shain 《Psychology in the schools》2011,48(6):556-572

Emotional support from classmates and teachers is a powerful protective factor in averting or reducing student mental health problems. Yet, longitudinal evidence indicates that there is decreased support from these groups as students advance to higher grade levels, a change that may be linked to diminishing mental health. This study followed 2,616 students from 23 high schools to test the hypothesis that perceptions of declining classmate and teacher support are associated with declining mental health. Growth curve analysis revealed significant decreases in support and self‐esteem and increases in symptoms of depression and social anxiety. Boys demonstrated steeper declines than girls in classmate support and self‐esteem and sharper increases in depression. As hypothesized, declining classmate and teacher support was associated with worsening self‐esteem and depression. Only declines in classmate support were associated with increases in social anxiety. Results were similar across gender categories. Implications for school‐based practices targeting social support are discussed. © 2011 Wiley Periodicals, Inc.  相似文献   

Alphabetization and the skewing of first authorship towards last names early in the alphabet     

Jonathan M. Levitt  Mike Thelwall 《Journal of Informetrics》2013,7(3):575-582

The practice of listing co-author surnames in alphabetical order, irrespective of their contribution, can make it difficult to effectively allocate research credit to authors. This article compares the percentages of articles with co-authors in alphabetical order (alphabetization) for two-author, three-author and four-author articles in eighteen social sciences in 1995 and 2010 to assess how widespread this practice is. There is some degree of alphabetization in all disciplines except one but the level varies substantially between disciplines. This level is increasing slightly over time, on average, but it has increased substantially in a few disciplines and decreased in others, showing that the practice of alphabetization is not fading away. A high correlation between alphabetical order and the proportion of first authors near the beginning of the alphabet confirms that high percentages of alphabetical order could affect the appropriate allocation of research credit. Similar patterns were found for science and the humanities. Finally, since some degree of alphabetization is almost universal in social science disciplines, this practice may be affecting careers throughout the social sciences and hence seems indefensible.  相似文献

Drive for Thinness and Fear of Fat Among College Women: Implications for Practice and Assessment     

Dana Heller Levitt 《Journal of College Counseling》2004,7(2):109-117

College women are at particular risk for developing eating disorders and related eating and body image concerns. The purpose of this article is to explore how both drive for thinness and fear of fat may be addressed in counseling with college women. Characteristics of drive for thinness and fear of fat as they relate to the development of eating disorders are addressed, and implications for college counseling and assessment of these constructs are presented.  相似文献   

Perceived Expectations Related to Promotion and Tenure: A National Survey of CACREP Program Liaisons     

Thomas E. Davis  Dana Heller Levitt  Jason M. McGlothlin  Nicole R. Hill 《Counselor Education & Supervision》2006,46(2):146-156

The purpose of the present study was to determine the perceptions of expectations and practices that contribute to decisions regarding promotion and tenure for counselor educators. Council for Accreditation of Counseling and Related Educational Programs liaisons for 74 counselor education programs responded to an Internet‐based survey about perceptions of promotion and tenure practices in their programs and institutions. The responses indicate that relatively equal emphasis is placed on teaching, scholarship, and service. Implications for defining promotion and tenure criteria are discussed, and recommendations for further research are provided.  相似文献
