Objectives: This study surveyed Web 2.0 application in three types of selected health or medical‐related organisations such as university medical libraries, hospitals and non‐profit medical‐related organisations. Methods: Thirty organisations participated in an online survey on the perceived purposes, benefits and difficulties in using Web 2.0. A phone interview was further conducted with eight organisations (26.7%) to collect information on the use of Web 2.0. Data were analysed using both quantitative and qualitative approaches. Results: Results showed that knowledge and information sharing and the provision of a better communication platform were rated as the main purposes of using Web 2.0. Time constraints and low staff engagement were the most highly rated difficulties. In addition, most participants found Web 2.0 to be beneficial to their organisations. Conclusions: Medical‐related organisations that adopted Web 2.0 technologies have found them useful, with benefits outweighing the difficulties in the long run. The implications of this study are discussed to help medical‐related organisations make decisions regarding the use of Web 2.0 technologies. 相似文献

We conducted a survey of radio station program directors and general managers to explore the perception and role of innovation within radio programming and the key factors that influence this perception. In the study, we found that, in general, programmers and general managers perceive little innovation in programming except at their own stations. Results also indicate perceptions that more risk taking is needed in radio programming, that risk taking is essential for the financial health of a station, that increased artist diversity and an innovative music rotation influence the perception of innovation at the station level, and that too many commercials are being placed within an average hour of programming. 相似文献

This study examines how good strategies and praxis interplay with positive affect and self-efficacy to determine a teacher's job satisfaction, in the hypothesis that teaching effectively does not in itself guarantee satisfaction: positive affect and self-efficacy beliefs are needed. Self-assessment scales, designed to assess the use of efficient teaching strategies and praxes, self-efficacy in teaching, positive affect and job satisfaction, were completed by 399 teachers. Structural equation modelling (SEM) analysis revealed the mediating role of both positive affect and self-efficacy beliefs in the relationship between teaching strategies/praxes and job satisfaction. 相似文献

The rise of educational action research amongst schools in Singapore can be attributed to the government's belief that educational research and reform can improve school performance and help Singapore keep pace with the impact of globalization. However, against a backdrop of neo-liberal educational reform where efficiency, accountability and demonstrable outcomes are valued, the underlying intent of the action research projects would seem to be inconsistent with the emancipatory intent normally associated with action research. A systematic review was conducted of 71 action research projects submitted to a local educational conference in 2006. Of concern to us is how action research has been narrowly interpreted and recruited simply as an evaluative tool with the emancipatory potential largely ignored. The paper is theoretically framed by governmentality and performativity to explore the embedded power relations that may “fabricate” the action research projects. The findings and discussions suggest a need for the government, schools and teacher-researchers to reflexively question the current expectation of action research and to be clear about its broader purpose. 相似文献

A test of advanced theory of mind (ToM), first introduced by F. Happé (1994) , was adapted for children (mental, human, animal, and nature stories plus unlinked sentences). These materials were closely matched for difficulty and were presented to forty-five 7- to 12-year-olds with autism and 27 control children. Children with autism who showed ToM impairment on independent tests performed significantly more poorly than controls solely on the mental, human, and animal stories with greatest impairment on the former and least on the latter. Thus, a mentalizing deficit may affect understanding of biologic agents even when this does not explicitly require understanding others' mental states. 相似文献

The goal of this paper is to explore qualities of mathematical imagination in light of a classroom episode. It is based on
the analysis of a classroom interaction in a high school Algebra class. We examine a sequence of nine utterances enacted by
one of the students whom we call Carlene. Through these utterances Carlene illustrates, in our view, two phenomena: (1) juxtaposing
displacements, and (2) articulating necessary cases. The discussion elaborates on the significance of these phenomena and
draws relationships with the perspectives of embodied cognition and intersubjectivity. 相似文献

Assaying parathyroid hormone (PTH) in the washing liquid after fine-needle aspiration biopsy (FNAB) seems to be a valid approach to locate parathyroid tissue. PTH-FNAB was evaluated in 47 patients with a clinical picture of primary hyper-parathyroidism (PHP) and ultrasonography (US) suggestive of parathyroid lesion. The patients were subdivided into two groups on the basis of the absence or presence of US thyroid alterations. The result of PTH-FNAB was compared with those of cytology, scintigraphy and, in 24 patients, surgical outcome. PTH-FNAB samples with a value higher than that recorded in the serum and higher than our institutional cut-off were deemed to be probable samples of parathyroid tissue. Cytology proved diagnostic for benign thyroid lesions, non-diagnostic for thyroid lesions, hyperplastic parathyroid tissue, undetermined or malignant thyroid lesions and other lesions in 45%, 30%, 17%, 4%, and 4% of cases, respectively. In 47% of cases, PTH-FNAB indicated that the sample had been taken in parathyroid tissue. In patients without US alterations, the diagnostic accuracy of PTH-FNAB was greater than that of scintigraphy. After surgery, comparison between the results of PTH-FNAB and scintigraphy, in terms of positive predictive value (PPV), revealed the superiority of PTH-FNAB; PPV was 94% for FNAB and 71% for scintigraphy, while sen-sitivity was 83% and 69%, respectively. PTH-FNAB evaluation after FNAB appears to be more diagnostic than cytology and scintigraphy. Of all the procedures used, PTH-FNAB appears to be the method of choice when the target is US suggestive and reachable. PTH-FNAB appears to be a useful method of guiding surgical intervention. 相似文献
