Over the years, the number of journals indexed in Scopus has increased, although it varies significantly between countries. The increasing proportion of international journals of a country provides new venues for papers from that country to be seen by other researchers worldwide. In this work, we evaluate the relationship of a country’s scientific performance or publication success with both its journals’ quantity and quality. The specific objective of the study is to identify the relationship between the country’s publication success and the quantity and quality of those country’s journals indexed in Scopus during 2005–2014. The publication success of 102 individual countries, measured by their scientific productivity, impact and collaboration indicators, the quantity of country’s Scopus-indexed journals in 2014 (a total of 22,581 journals) as well as the quantity of its journals were investigated. Scopus-indexed journals are predominantly from Western Europe (48.9%) and North America (27.7%), with the United States and the United Kingdom dominate with a total 51%. The contribution from the peripheral countries is comparatively small, however there are a good number of contributions from the South-East Asian countries. Estonia is the fastest growing country in terms of having indexed journals in Scopus, following by Iran and Malaysia. Among the studied indices, it was found that publication success (total publications and total citations) of 102 countries are strongly correlated with quantity (number of indexed journals and number of documents published in indexed journals) and quality (citations per paper, SJR, h-index, CiteScore and SNIP) indicators of country’s journals. We can conclude that the scientific productivity of a country depend critically on the number of journals indexed from that country in citation databases. The study provides a context with which the relative success of publications can be assessed, yielding new insights into the scientific impact of individual countries and the performance of journals that they published.  相似文献

The international mobility of scientists fosters knowledge exchange by increasing cross-country research collaboration between destination and origin countries. To the best of our knowledge, the mobility of international students, most of whom are not scientists, has not been linked to knowledge production involving both destination and origin countries in previous studies. The question of this research is whether international student mobility (ISM) contributes to science in China. To address this research question, we determined the annual number of international students studying in Chinese universities from 1999 to 2018, from the Concise Statistics of International Students in China compiled by the International Exchange Department of the Ministry of Education of the People's Republic of China, and corresponding publication records including the source country names in the titles, from the Web of Science database of Clarivate Analytics. We then used the fixed-effects negative binomial model and instrumental variable approach to explore the linkage from ISM to knowledge production and found that ISM led to the destination countries’ scientific research on foreign countries. The findings shed light on the discussion of the global mobility of talent, and contribute to the understanding of ISM's influence on science, the measurement of which is promising in future studies.  相似文献

The information needs of scientists in English-speaking countries have been studied and reported in the library literature. However, few studies exist on the information-seeking patterns of scientists in developing countries, and no study has examined the information needs of medical scientists in developing Asian countries. This study investigated the information needs of academic medical scientists at Chulalongkorn University in Bangkok, Thailand. The results indicate that medical scientists have three types of information needs: identifying up-to-date information, obtaining relevant studies and data, and developing research topics. Thai scientists' information-seeking behavior was different from that of scientists in developed countries. The study shows a high use of libraries as information providers; Thai medical scientists rely heavily on information from abroad.  相似文献

In the international motion picture market, when making strategic decisions about the timing of release, it is important to consider the product's country of origin as well as demand seasonality because of their cultural orientation. However, the fluctuation patterns of underlying demand for international market have not been distinguished from that of U.S. domestic market. Here, we analyze patterns of the decay effect, which represents the diminishing attractiveness of a movie over the product life cycle, and the seasonality of underlying demand for Hollywood and non-U.S. local movies in a non-U.S. market. We find a positive effect of U.S. holidays on the seasonality of underlying demand for Hollywood movies in the non-U.S. movie market, and a negative effect for non-U.S. local movies. The authors also find that the decay effect for Hollywood movies in the non-U.S. market is greater than that for non-U.S. local movies. These findings contribute to our understanding of the effect of country of origin on product life cycle and the seasonality of underlying demand, especially in movie-importing countries where local and Hollywood movies compete.  相似文献

This paper aims to investigate the practices of Pakistani academic researchers with respect to using, citing, and publishing their scholarly work. The quantitative survey method adopted to collect data from local researchers was based on an instrument developed and used by CIBER. Their notions and practices involved in deciding trust and quality of scholarly journals were obtained. The findings revealed that national and institutional policies have significantly influenced their decisions regarding the publishing outlets. The credibility of indexing services was found to be an important factor in choosing the journal for publishing research. ISI Web of Science Impact Factor was not considered as the top source for determining quality and trustworthiness. This study is the first of its kind that targets the top two universities of the country. A comparison of the findings with another international study shows that some of the behavioural traits are compatible with scholars from less‐developed countries like India and China, while others are more similar to the ones from highly developed countries like USA and UK.  相似文献

The article processing charge (APC) is currently the primary method of funding professionally published open access (OA) peer‐reviewed journals. The pricing principles of 77 OA publishers publishing over 1,000 journals using APCs were studied and classified. The most commonly used pricing method is a single fixed fee, which can either be the same for all of a publisher's journals or individually determined for each journal. Fees are usually only levied for publication of accepted papers, but there are some journals that also charge submission fees. Instead of fixed prices, many publishers charge by the page or have multi‐tiered fees depending on the length of articles. The country of origin of the author can also influence the pricing, in order to facilitate publishing for authors from developing countries.  相似文献

When a publication is cited it generates a benefit. Through the country affiliations of the citing authors, it is possible to work upwards, tracing the countries that benefit from results produced in a national research system. In this work we take the knowledge flow from Italy as an example. We develop a methodology for examination of how the knowledge flows vary across fields, in each beneficiary country. We also measure the field comparative advantage of countries in benefiting from Italian research. The results from this method can inform bilateral research collaboration policies.  相似文献

This study examines whether news broadcasts across nations are more cosmopolitan or parochial in their essence. To answer this question, the article proposes two unique theoretical concepts: “global newsworthiness” and “reversed domestication.” Global newsworthiness refers to news broadcasts that include ranges of countries, selected by several different reporting criteria. Reversed domestication refers to the connection made between the country of origin of the broadcasting media and the news content. Four television news networks were compared—CNN International, BBC World News, Al Jazeera English and France 24. The findings point to different levels of global newsworthiness and reversed domestication.  相似文献

Applying the health belief model, this study examined young adults' intention to adopt preventive behaviors against influenza infection in developing countries (Thailand and Cambodia) and developed countries (the USA and Singapore). Self-efficacy was the only variable significantly related to behavioral intention in the developing countries. In contrast, perceived threat, expected benefits, and media attention were significant predictors in the developed countries. Trust in information sources also had a consistent impact across the two samples. Theoretical and practical implications of the findings are discussed.  相似文献

The article investigates why a specific European issue is debatedin one country but disregarded in another, and why issues aredebated differently in different European countries. To understandthis national filtering, expectations are formulated as to howspecific policy traditions and issue-specific conflict constellationswithin a country are reflected in media debates. A systematiccontent analysis of the debates on EU enlargement and a commonconstitution for the years 2000–2002 in the German andFrench quality press reveals considerable variation in issuesalience, actors’ prominence and actors’ responsibilityattributions between and within the countries. This variationcan be seen to be connected with different policy traditionsand conflict constellations. The study seeks to go beyond merelydescribing variations in media coverage across Europe and systematicallyuses cross-national and cross-issue comparative research tounderstand this variation. Received for publication October 19, 2006. Accepted for publication April 5, 2007.  相似文献

The difference between the advanced and developing countries in the matter of access to information for research has been continually increasing. The advent of the Internet and electronic sources of information has not only exacerbated the gap but also led to the exclusion of developing country researchers from taking part as equal partners in publishing, refereeing, and in international collaboration. If handled imaginatively, the very same technologies can help bridge the information gap between the rich and the poor countries and help improve research productivity worldwide. Many initiatives that are already in place are described and suggestions are given on steps to be taken by developing country researchers.  相似文献

To guarantee a certain level of data usability, metadata which is information about the OGD, is needed. For this reason, OGD administrators provide metadata publishing guidelines to request, among other things, that certain metadata field always be present (completeness) and that field validation rules, when provided, be met (consistency). Lack of compliance of OGD metadata with publishing guidelines in country portals constitutes poor metadata quality control and will drastically decrease the effective use/reuse of the data and keep the expected benefits from being realized. This study explores the extent of metadata compliance, in terms of completeness and consistency, of three OGD leading country portals (Canada, USA, New Zealand) with respect to their own metadata publishing guidelines. A statistical comparison of population proportions among the countries was performed. The results indicate that the compliance of the USA is far less than Canada and New Zealand in terms of datasets with required fields set (completeness). On the other hand, New Zealand trails Canada and the USA in terms of OGD datasets with valid (consistent) fields. These results indicate that OGD metadata compliance is rather poor, suggesting insufficient quality control. Finally, this study concludes with suggestions to improve the OGD platforms so that metadata compliance can be automatically enforced.  相似文献

The purpose of this study was to examine whether scientific mobility, either between countries or between affiliations has an effect on researchers’ productivity and impact. In order to investigate this issue, we examined the relationships between the number of institutional affiliations and countries of the top 100 authors in seven disciplines. The selected authors’ profiles contained the number of affiliations and countries each author is assigned. We studied the number of affiliations and countries and compared them to three bibliometric indicators: the number of publications in international, peer-reviewed journals, h-index and Field Weighted Citations Impact. Our findings show that although there are differences in the relationship between mobility, productivity and impact between disciplines, mobility between at least two affiliations has an overall positive effect on both output and impact while mobility between countries does not. Therefore, in most disciplines positive impact and productivity effects are tracked in affiliation mobility within a single country.  相似文献

Objective:There are no existing validated search filters for the group of 37 Organisation for Economic Co-operation and Development (OECD) countries. This study describes how information specialists from the United Kingdom''s National Institute for Health and Care Excellence (NICE) developed and evaluated novel OECD countries’ geographic search filters for MEDLINE and Embase (Ovid) to improve literature search effectiveness for evidence about OECD countries.Methods:We created the draft filters using an alternative approach to standard filter construction. They are composed entirely of geographic subject headings and are designed to retain OECD country evidence by excluding non-OECD country evidence using the NOT Boolean operator. To evaluate the draft filters’ effectiveness, we used MEDLINE and Embase literature searches for three NICE guidelines that retrieved >5,000 search results. A 10% sample of the excluded references was screened to check that OECD country evidence was not inadvertently excluded.Results:The draft MEDLINE filter reduced results for each NICE guideline by 9.5% to 12.9%. In Embase, search results were reduced by 10.7% to 14%. Of the sample references, 7 of 910 (0.8%) were excluded inadvertently. These references were from a guideline about looked-after minors that concerns both OECD and non-OECD countries.Conclusion:The draft filters look promising—they reduced search result volumes while retaining most OECD country evidence from MEDLINE and Embase. However, we advise caution when using them in topics about both non-OECD and OECD countries. We have created final versions of the search filters and will validate them in a future study.  相似文献
