A cognitive model of intra-organizational knowledge-sharing motivations in the view of cross-culture     

Wei Jiacheng  Liu Lu  Calabrese A. Francesco 《International Journal of Information Management》2010

This paper explores individual cognitive mechanisms of knowledge-sharing (KS) motivation and intends to provide more effective measures to judge and influence individual inclinations toward KS in a cross-cultural context. First, it investigates four cognitive processes based on an individual's commitment toward KS, and studies through these processes how an individual's intrinsic motivation derived from social norms and personal norms, and extrinsic motivation derived from reward and punishment make concerted efforts to shape the ultimate intention to KS. Then, Hofstede's cultural framework is integrated to theorize cross-cultural differences in these processes. Finally, through a survey conducted in China and the US, the aforementioned theoretical analysis is confirmed. The results indicate that intrinsic motivation operates through affective commitment: internalization, identification and conformity; rewards have little direct effects on final intentions but they will influence attitude indirectly via identification; punishment for not sharing splits on cultural lines: Chinese tend to comply to avoid opposing their group and Americans tend to follow a more individualistic path; Chinese have more tendencies to conform to teams’ opinions and tend to favor KS as a means of achieving harmonious relationships, while Americans engage in KS because self-worth is viewed as the manifestation of their individual determinations.  相似文献   

The growth and crisis of Italian higher education during the 1960s and 1970s     

Corrado De Francesco 《Higher Education》1978,7(2):193-212

The expansion of the Italian university system in the 1960s and 1970s is described with particular reference to the laws of 1961 and 1969 which liberalized access. The effects of these reforms are discussed and it is argued that despite the expansion the system remains an élite system. Admission to prestigious faculties and failure rates are correlated with social class to show that selection by failure within the university may to some extent have replaced selection at entry as a way of maintaining an élite system. Despite the increase in wastage there is a growing mismatch between the demand for and supply of graduate labour and this has given rise to social tensions.  相似文献   

Teens’ alcohol consumption and schooling     

Francesco Renna 《Economics of Education Review》2008

While research outside economics has found that drinking has a negative effect on cognitive skills, some economists have failed to find any negative relationship between drinking and academic performance. This paper argues that the reason for this discrepancy is due to the way education is measured in the economic literature. Herein, binge drinking in the senior year of high school is found to reduce the probability of receiving a high school diploma and to increase the probability of graduating with a General Education Development (GED). Moreover, this study finds that alcohol policies do not affect the dropout rate measured at the age of 25, but they do affect the probability that a student will graduate on time. In conclusion, bingeing is found to be responsible for inducing individuals to temporarily drop out of school. Eventually, these individuals return to school to complete their education, most likely by obtaining a GED diploma.  相似文献   

The Diploma in Information Technology with Distance Teaching Methods     

Francesco Lata  Enrichetta Librandi 《European Journal of Engineering Education》1995,20(2):211-218

The Consortium for Distance University was founded in 1984 to set up a distance teaching university system in Italy. Its activity started in 1986 with the foundation of the Special Purpose School of Information Technology based on distance teaching methods. In 1991 a university diploma was established according to the European educational system. The 3‐year programme includes 28 learning modules and a final apprenticeship. The modules have been developed through a number of learning units, in the form of printed materials and computer‐aided instruction packages that enable learners to organize their own learning autonomously. Assistance to learners takes place in study centres where students meet tutors and use the hardware equipment needed for the software materials. In the academic year 1994/95, an experimental delivery of the university diploma in information technology through the CMC technologies will begin at some Italian universities so that it will be possible to demonstrate how the new modern technologies help students to manage their learning process in real time.  相似文献

Overcoming age barriers: motivation for mature adults’ engagement in education     

Francesco Marcaletti  Kleio Koutra 《International Journal of Lifelong Education》2013,32(4):451-467

ABSTRACT

Education is the main vehicle for empowering adults, and can contribute to community wellbeing. However, regarding mature adults (MAs) (over 45 years old), age has been identified in various studies as a significant barrier to accessing educational activities. This paper focuses on MAs’ motivations to learn through an exploratory survey undertaken in six European countries. A K-means cluster analysis based on 16 variables has been run on n = 846 valid cases. Four clusters describing distinctive behaviours and attitudes of MAs towards learning activities were identified. The study confirms that MAs’ motivations to learn are very diverse, overcoming some of the so-called myths of global aging, such as the homogeneity of MAs or the correlation between age and a decline in motivation to learn. Furthermore, analysing the main motivations of MA learners can be useful for adapting education to cater to their specific needs, boosting a more inclusive education, and promoting MAs’ empowerment.  相似文献   

Query reformulation mining: models,patterns, and applications   总被引：1，自引：0，他引：1  

Paolo Boldi  Francesco Bonchi  Carlos Castillo  Sebastiano Vigna 《Information Retrieval》2011,14(3):257-289

Understanding query reformulation patterns is a key task towards next generation web search engines. If we can do that, then we can build systems able to understand and possibly predict user intent, providing the needed assistance at the right time, and thus helping users locate information more effectively and improving their web-search experience. As a step in this direction, we build a very accurate model for classifying user query reformulations into broad classes (generalization, specialization, error correction or parallel move), achieving 92% accuracy. We then apply the model to automatically label two very large query logs sampled from different geographic areas, and containing a total of approximately 17 million query reformulations. We study the resulting reformulation patterns, matching some results from previous studies performed on smaller manually annotated datasets, and discovering new interesting reformulation patterns, including connections between reformulation types and topical categories. We annotate two large query-flow graphs with reformulation type information, and run several graph-characterization experiments on these graphs, extracting new insights about the relationships between the different query reformulation types. Finally we study query recommendations based on short random walks on the query-flow graphs. Our experiments show that these methods can match in precision, and often improve, recommendations based on query-click graphs, without the need of users’ clicks. Our experiments also show that it is important to consider transition-type labels on edges for having recommendations of good quality.  相似文献   

When Energy Conservation Seems to Fail: The Prediction of the Neutrino     

Francesco Guerra  Matteo Leone  Nadia Robotti 《Science & Education》2014,23(6):1339-1359

A historical case study concerning the serious doubts that arose in early 1930s about the validity of the law of energy conservation in nuclear disintegrations, and the hypothesis of neutrino, will be closely analyzed with the goal of promoting understanding of the nature of science. This work is based upon primary archival and printed sources, with a particular focus on the proceedings of the first International Conference of Nuclear Physics which was held in Rome on October 1931.  相似文献
