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
Essays on Labour Market Effects of Fiscal Policy
No full textThis thesis aims to contribute to the existing literature of fiscal policy with search and matching frictions using Dynamics Stochastic General Equilibrium (DSGE) modeling. This thesis consists of three essays (chapters) and the respective abstracts are as follows:
Title of first chapter is Labour Market Effects of Government Spending. In this chapter, I contributed to the Search and Matching Frictions (SMF) theory by examining the effects of fiscal multiplier shock on output and labour market for the US economy. I estimated US quarterly data and showed that government spending has positive
effect on output, employment, labour force participation, normalized vacancies, job finding probability and labour market tightness and negative effect on unemployment and real wages. This study contributes to the literature of SMF theory by estimating the model after inclusion of total job separation (a. as a combination of quits and layoffs, b. as segregated quits and layoffs) in the model. Positive government spending shock has a positive effect on total job separation and quits and negative effect on layoffs and average wages, which results in dispersion in wage distribution. This dispersion in wage distribution leads to income inequality. I also found that income inequality (gini) responded negatively to government spending shock, whereas P90/10 showed a positive response in short run and negative response in long run.
In the second essay, 'Fiscal Stimulus, On-The-Job-Search and Labor Market Dynamics', I theoretically examined the effects of government spending shock and aggregate productivity shock on the labour market using search and matching frictions. For this purpose, I developed a DSGE model using search and matching frictions and introduced two endogenous job separation margins (i.e., quits and Layoffs). I introduced quits as on-the-job-search with search effort and layoffs as operating cost. Results show that positive government spending shock has a positive effect on wages in good sector and a negative effect on wages in bad sector. Results also show that government spending increases job creation in good sector which leads to increase in job-to-job movements from bad to good sector. Fiscal policy shock has a negative effect on layoffs in bad sector. Using simulation, I calculated average wages by using both types of wages and both types of employment. Results show that initially there is a sharp decrease in average wage and subsequently showed increasing trend indicating wage inequality in labor market which results in movement of workers from bad to good sector.
In the third essay, 'Fiscal Policy with Labor Market Frictions', I investigated the effects of hiring subsidy (subsidy to the cost of posting vacancy) on US labor market in a DSGE model using search and matching frictions with two distinct margins of endogenous job separation i.e., quits through on-the-job-search and layoffs through
operating cost. The results show that hiring subsidy has a positive effect on job creation in both good and bad sectors. Hiring subsidy affects unemployment negatively in good sector and positively in bad sector. Hiring subsidy significantly affects wages in both sectors. All these results show that hiring subsidy has a positive effect on workers' welfare through wages and job creation. Results further show that firm's operating costresponded negatively to the hiring subsidy. Other variables also responded to positive hiring subsidy shock, but the effects are trivial
Female Education As A Determinant Of Economic Growth: The Case Study Of Pakistan
Full text linkThe contribution of female education has been very important in the GDP growth of the country, but this very sector has been ignored by the Government. This paper focuses on the importance of female education and highlights its significance for national development. It also brings out some impediments, obstacles and barriers confronting female education, especially the low level of the investment on the sector in the rural areas of Pakistan. The study further identifies the effects of female contribution in labor force participation. The study explores the opportunities to encourage the role of female in the developmental activities
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
