Abstract

This paper analyses the productive structure in Spanish television research. Data from theses about Spanish television which had been defended in this country over the period 1976/2007 was extracted. Two methodologies are used within this analysis: a bibliometric analysis and Social Network Analysis (SNA). Results show the production of theses by time period, university, these advisors and examination board members. The use of social networks leads us in the identification of notable academic groups operating in the present period as well as tendencies in the composition of the board in terms of university of origin and thesis advisor. There are 404 theses on television written in this period. The results indicate a general and constant increase in the number of theses, especially noticeable over the last 15 years. Regarding scientific production, the Complutense University of Madrid stands out as the most productive. The structural analysis shows that only the Complutense University of Madrid, the Autonomous University of Barcelona, University of Navarre and the University of La Laguna generate their own research groups. Professors shaping the Spanish research system for television are found through the analysis of social networks. Leading positions within the network structure are held by professors of communication from the Complutense University of Madrid and the Autonomous University of Barcelona.

Abstract

Sustainable transport infrastructure can determine the effect of countries&rsquo transport-driven economic returns. Considering the economic, environmental, and social relevance and growing issues of CO 2 in the countries concerned, this study aims to examine sustainable transport infrastructure related to economic return through a bibliometric and visualization analysis from 2000 to 2019. First, to measure the status of sustainable transport infrastructure literature, we determine the number of publications produced per year. Second, we determine the most frequently cited articles and prominent journals on sustainable transport infrastructure. Third, we examine the co-occurrence of the author&rsquo s keywords below the abstract. Fifth, we describe the bibliometric details in clusters and analyze the network link between reference, sources, and authors&rsquo co-citations, and discuss the characteristics and structures of clusters. Sixth, we discuss the bibliographic relationship between authors, and finally, determine the country and the institutional network of co-authors. The obtained results identify that the most influential articles, journals, and authors that make a significant contribution to sustainable transport infrastructure studies and present the research sub-areas or themes related to sustainable transport infrastructure. Overall, the study found the paradigms of today, key research areas, and the link between the fields of sustainable transport infrastructure studies. In the meantime, this study also reveals the improvements in the main topics and sub-sections over the last 20 years and shows the changes in future areas of research. The study concluded that the findings could provide researchers with some insights and help to advance studies on sustainable transport systems. Document type: Article
