Dissertation advising is an important form of mentoring. To investigate the impact of dissertation advising over time, advisor and committee member names were collected for 2400 dissertations completed over a 40-year period (1964–2004) in 32 North American information and library science schools. Several mentoring impact metrics are reported for a subset of the data, including the number of dissertations advised, the number of dissertation committees served on, the ratio of advising to committee membership, and the fractional “mpact” that weights advising and committee membership. The subset consists of data for six schools that produced at least three dozen dissertations and for which complete data is available. The data and resulting “mpact” metrics offer new ways to assess faculty impact and to investigate the nature and growth of a field. 相似文献

This article provides the first comparison of citation counts and mentoring impact (MPACT) indicators — indicators that serve to quantify the process of doctoral mentoring. Using a dataset of 120 library and information science (LIS) faculty members in North America, this article examines the correlation between MPACT indicators and citation counts. Results suggest that MPACT indicators measure something distinct from citation counts. The article discusses these distinctions, with emphasis on differences between faculty ranks. It considers possible explanations for weak correlations between citations and mentoring at the full professor rank as well as implications for faculty activity analysis and broader institutional evolution. 相似文献

This paper investigates beginning teachers collaboratively making sense of and responding to the micropolitical environments of their schools. Drawing on a qualitative multi-case study conducted within the context of a university-sponsored, inquiry-based induction program, this research employs a community of practice frame to examine how novice teachers came to practice “micropolitical literacy.” The paper identifies four dimensions of micropolitical discourse that surfaced in the situated setting of the inquiry groups. The analysis further illustrates how beginning teachers, while participating in inquiry groups, coconstructed understandings of the organizational structures and professional cultures of their schools. 相似文献

Research conducted primarily during the 1970s and 1980s supported the assertion that carefully constructed text illustrations generally enhance learners' performance on a variety of text-dependent cognitive outcomes. Research conducted throughout the 1990s still strongly supports that assertion. The more recent research has extended pictures-in-text conclusions to alternative media and technological formats and has begun to explore more systematically the whys, whens, and for whoms of picture facilitation, in addition to the whethers and how muchs. Consideration is given here to both more and less conventional types of textbook illustration, with several tenets for teachers provided in relation to each type. 相似文献

This forum presents Thailand's National Information Technology (IT) Plan and comments on the plan by three international experts: Seymour Goodman, Heinrich Reinermann, and G. Russell Pipe. The plan, which was prepared for Thailand's National IT Committee by the National Electronics and Computer Technology Center, is striking for its explicit consideration of social as well as economic goals in its specific objectives and implementation proposals. Agenda item 1 of the plan is to 'Invest in an Equitable Information Infrastructure: To Enhance Human Ability and Enhance Life Quality.' Implementation of the plan is proceeding well, although somewhat more slowly than anticipated, and support for the original goals and objectives remains strong. 相似文献

Circulating tumor cells (CTCs) are found in the blood of patients with cancer. Although these cells are rare, they can provide useful information for chemotherapy. However, isolation of these rare cells from blood is technically challenging because they are small in numbers. An integrated microfluidic chip, dubbed CTC chip, was designed and fabricated for conducting tumor cell isolation. As CTCs usually show multidrug resistance (MDR), the effect of MDR inhibitors on chemotherapeutic drug accumulation in the isolated single tumor cell is measured. As a model of CTC isolation, human prostate cancer cells were mixed with mouse blood cells and the label-free isolation of the tumor cells was conducted based on cell size difference. The major advantages of the CTC chip are the ability for fast cell isolation, followed by multiple rounds of single-cell measurements, suggesting a potential assay for detecting the drug responses based on the liquid biopsy of cancer patients. 相似文献
