This article provides an analysis of the academic performance of higher education institutions (HEIs) in Vietnam with 50 universities and 50 colleges in 2011/12. The two-stage semiparametric data envelopment analysis is used to estimate the efficiency of HEIs and investigate the effects of various factors on their performance. The findings reveal that HEIs in the surveyed sample show that there are still potential avenues to improve their existing performance. There appears to be a difference in the efficiencies of public and private HEIs in the reported year. It is noted that the inefficiency of HEIs are not entirely a result of managerial performance, but also influenced by other factors such as location, age and the contribution of tuition fees. Our results are expected to provide more understanding of the operational efficiency of HEIs for educational managers and policymakers to find possible solutions to improve the performance of Vietnamese higher education. 相似文献

The prevention and cure of cancer has been one of the great goals of medical science for many years. Although only partial success can yet be claimed, intensive research on an international basis has led to a greatly improved understanding of the mechanism of its causation. This masterly review of the current state of knowledge, by one of the most eminent research workers in this field, concludes on an optimistic note: there are sound grounds for supposing that cancerous cells can potentially be restored to their normal state and there are clues to ways of finding the kinds of substance which might effect this. 相似文献

This article presents conceptual navigation and NavCon, an architecture that implements this navigation in World Wide Web pages. NavCon architecture makes use of ontology as metadata to contextualize user search for information. Based on ontologies, NavCon automatically inserts conceptual links in Web pages. By using these links, the user may navigate in a graph representing ontology concepts and their relationships. By browsing this graph, it is possible to reach documents associated with the user desired ontology concept. This Web navigation supported by ontology concepts we call conceptual navigation. Conceptual navigation is a technique to browse Web sites within a context. The context filters relevant retrieved information. The context also drives user navigation through paths that meet his needs. A company may implement conceptual navigation to improve user search for information in a knowledge management environment. We suggest that the use of an ontology to conduct navigation in an Intranet may help the user to have a better understanding about the knowledge structure of the company. 相似文献

This paper explores the science content knowledge of elementary school teachers, and its possible role in helping them teach effectively. These issues are explored in the context of an investigation of the views of 106 elementary school teachers who had participated in professional development courses which focused on the topic “natural and processed materials.” These practising teachers revealed a range of conceptions about materials, which have been categorized into broad types. Some of the teachers showed shifts in conceptions, from what could be described as “naïve” conceptions to more scientific views, after a 2‐day professional development activity. © 2000 John Wiley & Sons, Inc.

ABSTRACTThis study investigated the effects of a 4-week training with hand paddles (HPD) on front-crawl swimming performance (SP), clean swimming speed (SPEED), stroke rate (SR), stroke length (SL) and tethered force (TF). Twenty swimmers (10 men and 10 women) were paired according to performance and gender, and were randomly assigned to control (CON, 22.4 ± 2.3 years) or HPD (21.8 ± 1.9 years) groups. During 4 weeks both groups performed the same training, except for a sprint training set (3 times/week, 10 × 10 strokes all-out, 1-min rest) completed with (HPD = 320 cm2) and without (CON) paddles. Afterwards, both groups performed the same training over a 2-week taper period. SP, SPEED, SR, SL and TF were assessed before (PRE) and after the 4-week period (POST), after the first (T1) and second taper weeks (T2). Swimmers rated their perceived exertion for the sprint training set (RPETS) and the training session for determining internal training load (ITL). SP, SPEED, SR, SL and TF did not change from PRE to POST, T1 and T2. ITL and RPETS were not different between groups. Training 4 weeks with HPD does not affect swimming performance, so the use of HPD remains unsupported in such period. 相似文献

How to align business analytics with process orientation initiatives and how management can influence a synergistic accomplishment of these two elements in order to streamline organizational performance is a foremost managerial issue. By means of a quantitative research effort, a study was designed to investigate the relationships among these constructs. Empirical data were collected in 2011 from a survey of 368 large and mid-sized industrial and service companies headquartered in Brazil. A quantitative analysis was performed, and both the reliability and validity of the scales were evaluated prior to using structural equation modeling. The results demonstrate that the direct effects among BPO, analytical indicators and performance can be taken as statistically significant. The findings also demonstrate that BPO and analytical indicators can be taken as predictors of performance. The paper discusses these results and their managerial implications, as well as some research paths for future studies on the topic. 相似文献

The general aim of our human nutrition project is to develop a health education model grounded in ‘everyday’ or ‘situated’
cognition (Hennessey, 1993). In 1993, we began pilot work to document adult understanding of human nutrition. We used a HyperCard
stack as the basis for a series of interviews with 50 adults (25 university students, and 25 adults from offcampus). The interviews
were transcribed and analysed using the NUDIST computer program. A summary of the views of these 50 adults on selected aspects
of human nutrition is presented in this paper.

The UNESCO International Bureau of Education (IBE), through the Community of Practice (COP) in Curriculum Development, organized
eight Regional Preparatory Workshops on Inclusive Education in 2007. These workshops had the overall goal of initiating a
participatory, consultative process in order to highlight key issues and challenges regarding inclusive education, to be presented
at the 48th session of the International Conference of Education (ICE) 2008. Each preparatory regional workshop centred on
four sub-themes around which the IBE Council has proposed to articulate the 48th ICE: Approaches, Scope and Content; Public
Policies; Systems, Links and Transitions; Learners and Teachers. In the framework of conceptual dimensions of inclusive education,
and the sub-themes of ICE 2008, this article identifies trends across regions within the ICE sub-themes and highlights points
for future debate on inclusive education.

Previous research has shown that indigenous students in Australia do not enjoy equal educational outcomes with other Australians. This secondary analysis of PISA 2006 confirmed that this continues to be the case in science literacy for secondary students. However, the analysis also revealed that indigenous Australian students held interest in science equal to that of their non‐indigenous peers, and that observed variations in science literacy performance were most strongly explained by variations in reading literacy. These findings hold important implications for teachers, teacher educators, policy‐makers, and researchers. Firstly, acknowledging and publicly valuing indigenous Australian science knowledge through rethinking school science curriculum seems an important approach to engaging indigenous students and improving their literacy in science. Secondly, appropriate professional learning for practising teachers and the incorporation of indigenous knowing in science methods training in teacher preparation seems warranted. Additionally, we offer a number of questions for further reflection and research that would benefit our understanding of ways forward in closing the science literacy gap for indigenous students. Whilst this research remains firmly situated within the Australian educational context, we at the same time believe that the findings and implications offered here hold value for science education practitioners and researchers in other countries with similar populations striving to achieve science literacy for all. 相似文献

This article discusses conceptual and empirical elements concerning the development of cognitive processes that function as precursors of reading, and their association with the acquisition of reading skills in an adult population participating in literacy courses. It connects emergent literacy research with historical–cultural and bioecological concepts. Subsequently, it focuses on the problem of the development of profiles of cognitive reading precursors. A sample of 63 Chilean adults was studied through a growth/learning curves approach. The study replicated previous results indicating the existence of three major profiles of these cognitive precursors. Together, these precursors are associated with significantly different learning curves beyond the effect of each precursor considered separately. In addition, it established a negative association between initial phonological awareness and the rate of reading acquisition during the course. It has been claimed that an individual's participation in specific cultural activities throughout his/her life influences the development of the precursors of reading. Based on a complementary biographical study of a subsample of participants, preliminary evidence is presented that supports this link. 相似文献
