Why transitional public relations methodologies are needed for the reform of higher education in the countries of central and eastern Europe     

Ryszard Ławniczak 《Higher Education in Europe》2003,28(4):529-538

This essay reflects upon the themes that emerged from the “Public Relations—An Instrument for the Transformation and Development of Higher Education in Central and Eastern Europe” seminar, for which the articles appearing in this issue of Higher Education in Europe were originally prepared. The transitional public relations approach, which was developed and introduced to the world public relations literature by the author, is used to analyze the impact of this type of public relations on the reform of higher education in the former communist countries of Europe. The main conclusion is that, in view of the common communist heritage of the countries of Central and Eastern Europe, the application of public relations strategies and instruments in higher education accelerates and facilitates reform of this key area of the economy and also causes it to become more effective. The above statement is particularly valid for private universities.  相似文献   

Syntactic manipulations and semantic interpretations in algebra: The effect of graphic representation     

Michal Yerushalmy  Rina Gafni 《Learning and Instruction》1992,2(4)

This study examined the effect of graphic representation of algebraic functions on performance of tasks involving expressions' transformations. Twenty eight teachers, who received instruction and practice using multiple representation software, were tested on their ability to debug faulty transformed expressions, either with or without graphic feedback. Two main strategies were used while debugging — Syntactic Manipulation (SYM) and Semantic Interpretation (SEI). It was found that subjects who used the SEI strategy, improved their performance while using graphs, as compared to no use of graphs. Some positive effect of the graphic feedback was also manifested for those using the SYM strategy, who were assisted by the graphs but continued to syntactically manipulate the expressions. All subjects improved their performance after the treatment, as measured by paper-and-pencil traditional tasks.  相似文献   

Usage patterns and social circles on Facebook among elderly people with diverse personality traits     

Fan Mo  Michal Kosinski  David Stillwell 《Educational gerontology》2018,44(4):265-275

Elderly people are exposed to information technologies to keep them in touch with younger generations. Among various technologies, social network sites (SNSs) are seldom used by the majority of elderly people. To bridge the digital divide, it is necessary to dig deeply into the minority elderly users of SNSs. This study explores usage patterns of elderly Facebook users and further investigates how their diverse characteristics influence their usage and social circles. Three findings were derived. First, a sharp digital divide on SNSs does exist, and existing elderly Facebook users are mainly the dabblers. Second, personality profiling could predict elderly people’s SNS usage behaviors. Elderly users with a high level of openness and extroversion have more friends, status updates, and group memberships, and those with a high level of conscientiousness have fewer likes and status updates. Elderly users are likely to seek insightful content on SNSs. Moreover, they may have a higher degree of emotional stability than young users when using SNSs. Third, elderly people tend to build small social circles on SNSs that “copy” the family relationship in the real world; whereas, they build large social circles with interests and hobbies that are difficult to share in the real world. Based on these results, detailed suggestions are presented for better targeting elderly people in ways that move them toward SNSs.  相似文献   

Between Ritual and Spiritual: Teachers’ Perceptions and Practices Regarding Prayer Education in TALI Day Schools in Israel     

Michal Muszkat-Barkan 《Journal of Jewish Education》2015,81(3):260-284

The aim of this qualitative study is to describe teachers’ perceptions and roles in prayer education in TALI day schools in Israel, using in-depth oral Interviews, written questionnaires and written materials of the schools’ network. Two educational ideologies were identified: Belonging to the Jewish collective and Personal-spiritual ideology. While participants perceive the aim of Jewish education as enhancing students’ belonging to the Jewish collective, prayer education introduces a personal-spiritual aspect that was not typically a part of teachers’ discourse on Jewish education.  相似文献

The microfluidic system for studies of carcinoma and normal cells interactions after photodynamic therapy (PDT) procedures     

Jedrych E  Chudy M  Dybko A  Brzozka Z 《Biomicrofluidics》2011,5(4):41101-411016

This study reports on the use of a microsystem for evaluation of photodynamic therapy (PDT) procedures on the "mixed" (carcinoma-normal) cultures. Balb/3T3 (normal mouse embryo) and A549 (human lung carcinoma) cells were tested in separated and "mixed" cultures. Interactions and migration of cells cultured together were observed. The PDT procedures were examined in the hybrid (PDMS/glass) microsystem which contains cell culture microchambers integrated with network of microchannels. We investigated that the number of dead cells after PDT procedures is dependent on the kind of cell culture. Moreover, the influence of the carcinoma cells on the viability of normal cells in the "mixed" culture was observed.  相似文献

Incidence and risk for traumatic and overuse injuries in top-level road cyclists     

De Bernardo N  Barrios C  Vera P  Laíz C  Hadala M 《Journal of sports sciences》2012,30(10):1047-1053

All traumatic and overuse injuries occurring during an average period of 4 years (2002/09) in a group of 51 currently active road top-level cyclists were retrospectively registered through clinical interviews. Average age was 25.8 years. Average training and competition period was 28.3 ± 2.4 h a week. Only 8 cyclists (15.6%) were completely free from lesions during the period of study. The remaining 43 cyclists suffered a total of 112 lesions; however, 9 out of these were unrelated to their cycling practice. These 103 cycling-related injuries include 50 (48.5%) traumatic and 53 (51.5%) overuse injuries. Twenty-eight fractures were reported, the clavicle being the most frequently affected bone (11 cases). The 68.5% of overuse injuries were located in the lower limbs. Most overuse injuries (89.6%) occurred during the training period. According to the injury abbreviated scale (AIS), severe lesions were only found in 4 cases (8% of traumatic injuries). Overall injury rates were 0.50 per racer/year, 2.02 per studied racer, and 0.007 per 1000 km of training and competition. Active professional top-level cyclists are exposed to a high injury risk. According to the scarce previously published data the current study provides relevant information on the injury occurrence of still active top-level road cycling.  相似文献   

On line Forums as a `Rescue Net' in an Open Inquiry Process     

Michal Zion 《International Journal of Science and Mathematics Education》2008,6(2):351-375

The Biomind program is a new open inquiry program for Israeli biology high school students. The Biomind program is facilitated by diverse activities of asynchronous on-line forums for teachers and students. This research aims to analyse the discussions that occurred over a period of three years in these forums, in order to obtain a picture of the benefits that virtual discussions hold for the implementation of the open inquiry program. The results presented in this article indicate that students required assistance mainly with searching scientific information, finding experimental techniques and procedures, and phrasing inquiry questions. The three most frequent areas that were discussed in the teachers' forum were technical and procedural aspects of experimentation, bureaucracy and phenomenon identification. In addition, issues such as inferring and discussing, logical progression of the inquiry process, scientific writing, teacher-student interaction, reflective thinking, affective points of view, and forum administration were raised in the forum discourses. The forum discourses create a learning community that contributes to the implementation of the Biomind program, and pinpoint the aspects that should be taken into consideration in the future.  相似文献
