This article analyses the effects of technology-mediated (i.e., social media) and in-person communication (i.e., non-verbal cues) on student satisfaction in a higher education context. Data were collected among 221 college students from the University of Valencia (UVEG) in Spain and analysed from the perspective of the respondents' national culture. Contrary to expectations, the results show that neither one of the social media aspects drives student satisfaction, thus providing support for the technology paradox literature. Instead, three non-verbal communication cues are found to influence student satisfaction, i.e., paralanguage, kinesics, and chronemics. The moderating role of national culture on the examined relationships is also considered. The results reveal that national culture seems to only affect the relationship between chronemics and satisfaction.  相似文献

Following a tour d'horizon of the development of science and science policy in former Yugoslavia, the author focuses on the application of science to development in this country after the Second World War. In particular, she examines the role of computer science in which Yugoslav scientists developed much endogenous capacity. The events following the break-up of Yugoslavia led to the isolation and the emigration of scientists, academics, and graduate students, particularly from Serbia, in the reduced Yugoslavia that remained after the break-up. During the period of sanctions, Yugoslavia was denied even the right to participate in TEMPUS projects that were underway. The TEMPUS III projects in which Yugoslavia can participate are not very helpful in rebuilding the scientific capacity of the country. The country needs assistance, possibly best given through twinning arrangements with universities in other countries, to rebuild its scientific capacity. Economic aid to rebuild infrastructures is also needed. Only when talented young scientists can look forward to a future at home will they no longer seek to emigrate.  相似文献

Based on findings from a semester-long study, this article examines the development of Samoan prospective teachers’ mathematical understandings and mathematics attitudes when investigating authentic contexts and applying working mathematically processes, mental computations and problem-solving strategies to find solutions of problems. The prospective teachers had enrolled for the second time (having failed their first attempt), in the first-year mathematics methods course of a 2-year Diploma of Education (Primary) programme. The group also included those enrolled in the Diploma of Education (Early Childhood and Special Needs) programmes, who recognizing their own limited understanding of mathematics would ordinarily shy away from opportunities for improvement. Given the negative mathematical and learning experiences, this group was ideal to engage in innovative and creative approaches that would make mathematics learning more meaningful and contextual in a Samoan environment. Only data from the attitudinal questionnaires and interviews are presented in this article. Main findings have implications for teaching and learning mathematics.  相似文献

The Federal Assembly of the Czechoslovak Socialist Republic approved, on 10 April 1980, the new law (Nr.39/80) on higher education. This law was under preparation nearly three years by the Czech and Slovak ministries of education and representatives of universities and other institutes of higher education as we'll as experts in charge of economic and social development. Starting from 1 September 1980 it will replace the previous law on higher education (Nr. 19/66) that has been in effect since 1966.

The following article, written for “Higher Education in Europe” by Professor Jiri M#akeri?ka, Director of the Research Institute on Engineering Studies in Prague, presents the main elements of this new law.  相似文献

All live systems acquire and use knowledge to ensure appropriate efficiency in the mutual intercourse with the surrounding environment. Knowledge can be communicated only when the subject's internal model of the object of reality is objectified by means of a certain set of physical signs. Such an externalized model, a communicate, is to be accepted, adequately understood and evaluated by other relevant live systems. The information value of a communicate is therefore a function not only of the communicate itself but of the needs, aims, expectations and possibilities of relevant live systems as well. The information value of the same communicate can vary within a set of those systems. The determination of regularities in the relations between the information value of communicates, their content similarity and distinctive features of live systems producing and using them is a problem for experimental and empirical studies.  相似文献
