Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Higher education expansion and graduate labour market outcomes in Spain: overqualification and its discontents
Full text linkThis is a mixed methods study about graduate educational and skill mismatch in Spain. The study examines the evolution of graduate mismatch at the macro level, investigating changes in the number of tertiary graduates vis-à-vis-the number of high-skilled jobs in the economy. The proliferation in the share of graduates unable to find high-skilled jobs in Spain has accentuated policy concerns that the number of graduates has increased faster than the number of high-skilled occupations available. Graduates are consequently "bumped down" the occupational ladder and forced to take up lower-skilled jobs, a situation defined in this thesis as occupational drifting down.
The first part of this thesis is dedicated to exploring the determinants of graduate labour market mismatch, with focus on the influence of educational track and field of study on the probability of graduate employment and occupational drifting down. Drawing on the Spanish Labour Force Survey for 2006 and 2012, this study provides an original analysis of the determinants of employment and occupational drifting down among Spanish graduates, employing logistic models to evaluate the influence of personal, educational and occupational characteristics.
The fact that these graduates are employed in jobs that one generation ago were occupied by non-graduates, however, does not automatically indicate that the demands of these occupations has remained the same. Since job content is not fixed, the quantitative methods employed in this thesis alone are insufficient to determine the skill requirements of occupations and changes in job content over time. This study, therefore, uses the multiple-case study approach to investigate changing skill requirements within occupations. To this end, 50 in-depth interviews with senior managers and graduates in the retail banking and retail trade industries were conducted in Spain between January 2015 and March 2016.
In gaining proximity to the real-life context of graduate mismatch in the workplace, this study seeks to advance scholarship on graduate skills utilization and hiring trends at the sectoral level, providing novel insight into the changing skill requirements of two industries in Spain. In this way, this study fills a research gap, as sectoral case studies are sparse in the literature (Caroli et al., 2008; Elias and Purcell, 2004; Mason, 2002; Green and McIntosh, 2002, Knights and McCabe, 1998, Mason, 1996), particularly for Spain. </p
Measuring financial literacy and its correlates: a study of fifteen-year-olds in Oxfordshire and Greater London
Full text linkFinancial literacy refers to one's ability to apply knowledge and skills in order to make informed financial decisions. Both internationally and within the UK, there have been many initiatives designed to improve people's financial literacy. In particular, there has been much emphasis placed on providing financial education for young people at school. However, there has been a lack of research evidence from the UK about the levels of young peopleâs financial knowledge, skills and attitudes. In this study, an instrument was designed to measure these key aspects. There is a personal finance test within the instrument which can produce a combined measure of financial knowledge and skills. There is also a separate section to measure levels of desired financial attitudes towards various personal finance topics. Background information was also collected from respondents in order to allow us to examine the correlates of financial literacy. The initial instrument was piloted on a group of students and validated by some subject matter experts. The final instrument was used to assess the financial literacy of a convenience sample of 3115 fifteen-year-olds from 28 schools in Oxfordshire and Greater London. The results of the personal finance test illuminated the specific topics that young people were weak in, such as understanding the workings of credit cards and compound interest. In terms of financial attitudes, the majority indicated that they were very confident about managing their own money; there was a high propensity to save money and to want to become financially independent. However, levels of desired attitudes towards spending and debt were found to be relatively low. The main correlates of financial knowledge and skills were literacy and numeracy levels, whilst financial attitudes were more strongly associated with personal characteristics. The relationships between the personal finance test scores and financial attitudes were mostly positive. </p
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
