A Panel Data Econometric Study of Corporate Tax Revenue in European Union: Structural, Cyclical Business and Institutional Determinants
Get PDFThis paper studies the economic determinants of corporate tax revenue to Gross Domestic Product (GDP) across European Union members over the period 1998-2009. The Feasible Generalized Least Squares (FGLS) regression results suggest that structural, cyclical, international and institutional factors such as GDP, Government Deficit, Industry Turnover, Unemployment, Number of Enterprises, Trade Openness, Foreign Direct Investment (FDI) and Corruption affect revenue performance of an economy. Thus, the findings show that Unemployment Rate and Corruption have an adverse effect on tax collection, while the other analysed factors contribute to a better performance concerning tax collection. In the present paper we also consider as explanatory factors the tax variables Effective Average Tax Rate (EATR) and Effective Marginal Tax Rate (EMTR). In fact, empirical results indicate a parabolic relationship between EMTR and corporate tax revenues, reinforcing the hypothesis of the existence of a Laffer curve. Our findings also suggest that the last two years of European Union enlargement are likely not to have had effect in corporate tax revenue to GDP. In addition, specific factors of some countries (Greece, Portugal and Spain) seem to positively affect corporate revenues.Corporate Tax Revenue, EATR, EMTR, Corruption, Laffer Curve
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Programmes to Protect the Hungry: Lessons from India
Get PDFEvidence on calorie intake and nutritional outcomes establishes that chronic hunger and food insecurity persist today on a mass scale in India. The liberalization-induced policy of narrow targeting of the Public Distribution System (PDS), a programme of food security that provides a minimum quantity of cereals at subsidized prices, has resulted in worsening food insecurity. Recent evidence from the 61st round of the National Sample Survey in 2004-2005 establishes that targeting has led to high rates of exclusion of needy households from the system and clear deterioration of coverage in States like Kerala where the universal PDS was most effective.food security, targeting errors, India, liberalization, public distribution
Variations on the Author
Get PDF“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
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
