The purpose of this study was to determine and analyze the annual cost of operation including depreciation of movable capital equipment for educating one student in each curriculum of selected community colleges and to show the relationship of costs of vocational-technical curricula to the cost for common baccalaureate oriented curricula.A stratified sample of eight community colleges was drawn from those that had been in operation for at least five years.These data indicate that a majority of the courses offered in highly specialized curricula in both the occupational and baccalaureate categories were more expansive than those courses that were common to a wide variety of curricula.This study supports differential program funding to assure continued development of high quality vocational-technical programs in community colleges.  相似文献

Face‐to‐face education and distance education, viewed as differing sets of organisational provisions for the fostering of learning, emphasize different kinds of learning processes, and depend upon somewhat different psychological properties in learners. Nonetheless, all practical learning settings, whether they are labelled ‘school’, ‘adult education’, ‘distance education’, or something else, involve a mixture of face‐to‐face learning and distance learning. The psychological difference between the two kinds of setting is thus note purely qualitative in nature, but is also quantitative: for instance, certain learner characteristics which are useful in face‐to‐face learning (discussed in detail in the body of the present paper) are indispensible for distance learning, while certain processes which are at the heart of distance learning (also dis‐cusssed in detail later) are often given little emphasis in face‐to‐face settings, although they are in principle possible and even desirable there. The question thus arises of whether it would not be desirable to give more emphasis in face‐to‐face settings to psychologically desirable aspects of distance learning.  相似文献

Twenty-six normal first-grade children (M = 7.0 years) were administered the WISC-R, the McCarthy Scales, and the Woodcock-Johnson Scales of Cognitive Ability. Two years later, their levels of academic achievement were determined by way of the WRAT and global teacher ratings of classroom performance. Pearson intercorrelations among the summary indices of the three intellectual measures were significant and uniformly high (rang. 77-.95). Correlations between first-grade ability scores and third-grade achievement measures also were significant (range .64-.90), suggesting strong predictive validity for each of the cognitive instruments. Though not significantly so, the correlations between the Woodcock-Johnson and achievement tended to be the highest. The results indicate that all three intellectual measures are appropriate for predicting later academic achievement in young school-aged children.  相似文献

This paper reports on the results from a detailed national audit of information communication technology (ICT) in physical education (PE), examining attitudes, training, numbers of pieces of equipment and hardware owned, and its employment and use across nine Local Education Authorities, six types of schools, and four types of Specialist College. After setting the context, a summary of the survey methods used and an overview of the findings from 500 schools are presented. Results from 252 questionnaires returned suggested that the majority of PE teachers felt that ICT was a valuable teaching tool; however, parity of training and ownership of equipment were not standard across the range of schools or regions. Furthermore, the data suggest a growing trend in ICT use in PE across England.  相似文献

The evolution of trust in information technology alliances   总被引:2,自引:0,他引:2  
As strategic alliances become an increasingly important weapon for companies in achieving a competitive advantage, an important subject of investigation has become those factors that contribute to the success of the alliance. Trust between the alliance partners has been proposed to be one of those critical success factors. The high levels of uncertainty and interdependence that characterizes high technology alliances make trust particularly important in these contexts. Very little is known, however, about the process of trust creation or erosion in strategic alliances. This study addresses this shortcoming in cross-sectional trust research by utilizing a longitudinal survey design to examine the antecedents and outcomes of trust formation between strategic alliance partners. We contrast a transaction cost economics view of trust with a social exchange perspective to more fully explore what may influence changes in the level of trust between partners. Results suggest that the development of trust was not a function of the formal incentive systems that transaction cost economists deem necessary to prevent opportunistic behavior. Conversely, factors from social exchange theory – communication, shared values, and relationship equity – provide a more thorough explanation of what contributes to the development of higher levels of organizational trust. Finally, this study provides evidence that as trust increases between partners, the alliance benefits by displaying higher levels of dependence, higher levels of partner learning, and higher levels of performance.  相似文献

The dramatic advancements in the field of vaccinology has led to the formulation of chemically well defined vaccines composed of synthetic peptides and recombinant proteins derived from the immunologically dominant regions of the pathogens. Though these subunit vaccines are safer compared to the traditional vaccines they are known to be poorly immunogenic. This necessitates the use of adjuvants to enhance the immunogenicity of these vaccine formulations. The most common adjuvant for human use is alum. Research in the past has focused on the development of systemic immunity using conventional immunization protocols. In the present are, the emphasis is on the development and formulation of alternative adjuvants and delivery systems in generating systemic as well as mucosal immunity. This review mainly focuses on a variety of adjuvants (particulate as well as non-particulate) used with protective antigens of HIV, malaria, plague, leprosy using modified delivery vehicles. The experience of our laboratory and other researchers in this field clearly proves that these new age adjuvants and delivery systems undoubtedly generate enhanced immune response-both humoral and cell mediated. The choice of antigens, the nature of adjuvant used and the mode of delivery employed have a profound effect on the type of immune response generated. Besides the quantity, the quality of the antibodies generated also play a vital role in protection against these diseases. Some of the adjuvants and delivery systems used promoted high titre and affinity antibodies, which were shown to be cytophilic in nature, an important criteria in providing protection to the host. Thus the studies on these adjuvants/delivery systems with respect to various infectious diseases indicate their active role in efficient modulation of immune response along with safety and permissibility.  相似文献

Linguistic influences on networks of professional communication and recognition among engineers at two Quebec universities were examined. It was hypothesized that chemists and engineers affiliated with the French medium University of Montreal and the Ecole Polytechnique would be less active in research and more likely to obtain scientific recognition locally and to feel professionally unrecognized outside Quebec compared to their colleagues at McGill University. The findings suggest that the localizing effects of using a medium of scientific training which is not the predominant language of international scientific communication and recognition (French) are ambiguous. Although chemists and engineers at the French medium institutions were less active researchers, their language of professional communication with other scientific communities was English and there was little sense of isolation.This research has been supported by grants from the Canadian Council and the Ecole Polytechnique of Montreal. The authors also wish to thank Miss Madeleine Palmer, Miss Daniella Quiniou and Miss Rosalba Casas for their help in data collection for this paper.  相似文献
