Ethnic differences in utilization of online health information sources : A test of the social inequality hypotheses
2023
The goal of the current study was to understand ethnic differences in use of online health information sources. Social stratification and social diversification hypotheses were used as study’s theoretical framework. The data were obtained from the 2017 Israel Social Survey (N = 2166). Multinomial and logistic regression techniques were used for the multivariate analysis. The results suggest that Israeli Arab respondents were less likely than Israeli-born Jewish respondents to seek health information using the Health Funds’ call centers or websites, other websites, and to utilize any number of the online health information sources. The findings provide a strong support for the social strati…
Students’ online information use and learning progress in higher education – A critical literature review
2021
Learning using the Internet has become a vital factor for academic success in higher education. Students increasingly rely on the Internet as their main information source. However, related researc...
A longitudinal study on the information needs and preferences of patients after an acute coronary syndrome.
2016
Background Research has shown that the provision of pertinent health information to patients with cardiovascular disease is associated with better adherence to medical prescriptions, behavioral changes, and enhanced perception of control over the disease. Yet there is no clear knowledge on how to improve information pertinence. Identifying and meeting the information needs of patients and their preferences for sources of information is pivotal to developing patient-led services. This prospective, observational study was aimed at exploring the information needs and perceived relevance of different information sources for patients during the twenty-four months following an acute coronary synd…
A Survey on how to Cross-Reference Web Information Sources
2015
International audience; The goal of giving information a well-defined meaning is currently shared by different research communities. Once information has a well-defined meaning, it can be searched and retrieved more effectively. Therefore, this paper is a survey about the methods that compare different textual information sources in order to determine whether they address a similar information or not. The improvement of the studied methods will eventually lead to increase the efficiency of documentary research. In order to achieve this goal, the first category of methods focuses on semantic measure definitions. A second category of methods focuses on paraphrase identification techniques, an…
The effect of time and place dependence when utilizing video lectures
2009
In many learning institutes, diversification of teaching with the help of various technologies has become an essential part of educational arrangements. With the increase in the use of networks for teaching purposes, the use of streaming videos is now one of the possibilities to be reckoned with in trying to increase flexibility in studies. Specially recorded on-demand videos provide the students with better chances to decide when, where and how to study. Information on how students use on-demand videos can be obtained, apart from student questionnaires, from the log files of a media server. These files offer an information source that, on the one hand, is diverse but, on the other, cumbers…
Consumers perception of food safety related risk in the italian market
2019
The aim of this paper is to define the factors affecting the consumers' perception on food risk associated to the consumption of products (i) containing food additives, (ii) obtained with the use of pesticides, and (iii) processed through novel food technologies, in relation to different socio-economic and demographic characteristics, the source of acquisition of information on food safety issues, and the place of purchase of food. The study is based on a sample of 392 consumers, living in Italy, and it uses three ordered probit estimation models to process data collected. Findings show that food risk perception is greater among youngsters, mainly for the additives and residual pesticides i…
Extended GT-STAF information indices based on Markov approximation models
2013
Abstract A series of novel information theory-based molecular parameters derived from the insight of a molecular structure as a chemical communication system were recently presented and usefully employed in QSAR/QSPRs (J. Comp. Chem, 2013, 34, 259; SAR and QSAR in Environ. Res. 2013, 24). This approach permitted the application of Shannon’s source and channel coding entropic measures to a chemical information source comprised of molecular ‘fragments’, using the zero-order Markov approximation model (atom-based approach). This report covers the theoretical aspects of the extensions of this approach to higher-order models, introducing the first, second and generalized-order Markov approximati…

Accuracy and Completeness of Drug Information in Wikipedia: A Comparison with Standard Textbooks of Pharmacology
2014
The online resource Wikipedia is increasingly used by students for knowledge acquisition and learning. However, the lack of a formal editorial review and the heterogeneous expertise of contributors often results in skepticism by educators whether Wikipedia should be recommended to students as an information source. In this study we systematically analyzed the accuracy and completeness of drug information in the German and English language versions of Wikipedia in comparison to standard textbooks of pharmacology. In addition, references, revision history and readability were evaluated. Analysis of readability was performed using the Amstad readability index and the Erste Wiener Sachtextforme…
Personal data in a large digital library
2000
The RePEc Economics library offers the largest distributed source of freely downloadable scientific research reports in the world. RePEc also contains details about Economics institutions, publication outlets and people working in the field. All this data forms a large relational dataset. In this paper we describe HoPEc, a system that allows to implement access control records personal data within RePEc. The bulk of these records describe the authors of documents. These records are maintained by the authors themselves. We discuss the technical and social aspects of this system.
