Although the law of libel and other forms of defamation seems to undergo change with every new term of the U.S. Supreme Court, it is hoped that this “here is how it is in the summer of 1971” review will be of value. Dr. Milan Meeske is assistant professor in the Department of Communication of Florida Technological University.  相似文献

We present a straightforward and rapid surface acoustic wave (SAW) atomization-based technique for encapsulating proteins into 10 μm order particles composed of a biodegradable polymeric excipient, using bovine serum albumin (BSA) as an exemplar. Scans obtained from confocal microscopy provide qualitative proof of encapsulation and show the fluorescent conjugated protein to be distributed in a relatively uniform manner within the polymer shell. An ELISA assay of the collected particles demonstrates that the BSA survives the atomization, particle formation, and collection process with a yield of approximately 55%. The SAW atomization universally gave particles with a textured morphology, and increasing the frequency and polymer concentration generally gave smaller particles (to 3 μm average) with reduced porosity.  相似文献

The 2006 Programme for International Student Assessment focussed on students’ scientific competencies, measured their knowledge and provided questionnaires focussed on different aspects of life. One aspect was students’ experience with information and communication technology (ICT). A secondary analysis of variance of the Czech Republic data (N?=?5,932 students) was conducted using the science knowledge test score and ICT familiarity items. The science knowledge items explored different thematic areas, such as evolution, mousepox, genetics and acid rain. The main result was that students who were connected in some way with ICT achieved better scores on the science knowledge test in comparison with students who were not. Furthermore, students whose ICT activity was connected with the educational process achieved a higher score in comparison with students whose ICT activity was not connected with the educational process.  相似文献

Abstract

In this study, we examined the effects of time-of-day-specific strength training on maximum strength and electromyography (EMG) of the knee extensors in men. After a 10-week preparatory training period (training times 17:00–19:00 h), 27 participants were randomized into a morning (07:00–09:00 h, n = 14) and an evening group (17:00–19.00 h, n = 13). Both groups then underwent 10 weeks of time-of-day-specific training. A matched control group (n = 7) completed all testing but did not train. Unilateral isometric knee extension peak torque (MVC) and one-repetition maximum half-squat were assessed before and after the preparatory training and after the time-of-day-specific training at times that were not training-specific (between 09:00 and 16:00 h). During training-specific hours, peak torque and EMG during MVC and submaximum isometric contraction at 40% MVC were assessed before and after the time-of-day-specific training. The main finding was that a significant diurnal difference (P < 0.01) in peak torque between the 07:00 and 17:00 h tests decreased after time-of-day-specific training in the morning group but not in the evening or control groups. However, the extent of this time-of-day-specific adaptation varied between individuals. Electromyography during MVC did not show any time-of-day-specific adaptation, suggesting that peripheral rather than neural adaptations are the main source of temporal specificity in strength training.  相似文献

Students’ evaluations of teaching are increasingly used by universities to evaluate teaching performance. However, these evaluations are controversial mainly due to fact that students value various aspects of excellent teaching differently. Therefore, in this paper we propose a new approach to students’ evaluations of university teaching based on data from conjoint analysis. Conjoint analysis is a multivariate technique used to analyze the structure of individuals’ preference. In particular, our approach accounts for different importance students attach to various aspects of teaching. Moreover, it accounts explicitly for heterogeneity arising from students’ preferences, and incorporates it to form comprehensive teaching evaluation score. We have conducted survey and confirmed applicability and efficiency of the proposed approach.  相似文献

This study describes an approach to learning and teaching that is structured as a project‐based context‐driven inquiry. The approach is positioned at the interface between knowledge‐generation and use, and grounded in a generic notion of responsibility for the future of bodily life. The intention is to move the debate beyond the exhausted language of rigid oppositions between the academic and vocational, the universal and contextual. The purpose is to identify and nurture a personal portfolio of competencies responding to the contemporary material condition of humanity. It is expressed in terms of the student's learning power, a manifold of new assessment criteria and methodological steps constitutive of what a student could achieve having progressed through a given course. This is an approach in which competencies are outcomes supported rather than led by subject knowledge. The course structure combines traditional instruction with innovative project and assessment components and also provides an opportunity for the student to get acquainted with an employment niche. The practical applications of this approach at university and secondary‐school levels have led to encouraging results for both staff and learners.  相似文献

This article provides insight into the state of higher education in Serbia, particularly in the context of reform processes based on European Higher Education Area principles. A multidimensional approach was taken, encompassing (a) a review and analysis of legal regulations relevant to the historical context of Serbia, (b) an examination of current working conditions at accredited state and private higher education institutions, (c) and a pilot survey of attitudes among the main participants in higher education teaching. The research gauged attitudes of university professors and students with work or study experiences, respectively, at both state and private higher education institutions. Specific instruments for measuring attitudes were constructed for this study. Professors' attitudes toward state and private higher education were compared through the assessment of aspects of organisational culture including work organisation, stimulating atmosphere, innovation, and creativity. Students expressed their attitudes toward state and private higher education in terms of general atmosphere, curricula, grading criteria, and student status. The results indicate that private higher education was appreciated slightly more than state higher education; both professors and students held more positive attitudes of private higher education for all dimensions investigated.  相似文献

A study carried out in 1998 (reported in the Journal of Agricultural Education and Extension, 2003) of the information systems used by farmers in the Czech Republic to access information and advice was repeated in 2003. The research aim was to assess whether, and how, the systems had changed during these five years. The perceived importance of 10 categories of information relating to farming had changed little during this time. The sources used to obtain this information, and related advice, had, however, been less stable. The relative importance of half the sources used had changed to higher or lower levels. The sources of high importance for information are largely institutional; for advice they are more social. There is an increasing need for professional consultants and horizontal transfer of information is important as well. There was no evident consistent trend in the size of the information systems, measured as the actual numbers of sources used, but it is possible that there is a move towards smaller numbers, especially for advice. There has been a large investment in computers on farms since 1998. A good start has been made in developing a system of professional consultants for farmers. Optimism about the future has declined a little among the private farmers, though it remains higher than on the co-operative and company farms, despite the uncertainties facing agriculture. More study is needed to assess the adequacy of the information systems for farmers undertaking diversification.  相似文献

One aspect of the recent pressure for greater public access to the airwaves is the attempt by several individuals and groups to buy air time for expression of opinion on often controversial subjects. The legal ramifications of this issue are explored in the following paper by Dr. Milan Meeske, a member of the communication faculty at Florida Technological University in Orlando.  相似文献
