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
A golden rule of public finance or a fixed deficit regime?: Growth and welfare effects of budget rules
No full textIn this paper, we compare growth and welfare effects of various budget rules within an endogenous growth model with productive public capital, utility enhancing public consumption and public debt. We find that introducing a fixed deficit regime does not affect the long run growth rate compared to a balanced budget while establishing a golden rule results in higher growth. Simulations of welfare effects indicate that a golden rule leads to highest welfare followed by a balanced budget and a fixed deficit regime. A maximum fraction of deficit financed public investment is derived. Varying the intertemporal elasticity of substitution shows that economies populated by households who have a strong tendency to smooth consumption should adhere to a balanced budget from a welfare point of view.Budget rules Golden rule of public finance Fiscal policy Endogenous growth Welfare
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
It Sucks to Be Single! Marital Status and Redistribution of Social Security
Get PDFIn this paper, we study the labour supply effects and the redistributional consequences of the U.S. social security system. We focus particularly on auxiliary benefits, where eligibility is linked to marital status. To this end, we develop a dynamic, structural life cycle model of singles and couples, featuring uncertain marital status and survival. We account for the socio-economic gradients to both marriage stability and life expectancy. We find that auxiliary benefits have a large depressing effect on married women’s employment. Moreover, we show that a revenue neutral minimum benefit scheme would moderately reduce inequality relative to the current U.S. system.<br/
Bequests and Informal Long-Term Care Evidence from HRS Exit Interviews
No full textInformal long-term caregiving for frail elderly individuals by their children may induce parents to compensate their children for their help. To test this hypothesis, I use the exit interview from the Health and Retirement Study (HRS). My results show that the decision to care for one's parents has a significant positive impact on the incidence and amount of bequests received. In addition, increasing the amount of care relative to one's siblings significantly increases the proportion of bequest within a family. Furthermore, I find that the positive nexus of caregiving and bequest requires a written will as a contract between the parent and the helping child
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
Es glänzt nicht alles, was gold ist. Wachstums- und Wohlfahrtswirkungen von Budgetregeln
No full textDie Arbeit vergleicht drei prominente Budgetregeln zur Begrenzung der Fiskalpolitik sowohl institutionell als auch theoretisch: die Goldene Regel, eine Fixe Defizitquote und ein strukturelles Schuldenverbot. In Kapitel 2 wird zunächst eine allgemeine Begründung für Budgetregeln geliefert und die untersuchten Budgetregeln und deren Intention werden vorgestellt. In den Kapiteln 3 bis 5 erfolgt eine theoretische Analyse der Auswirkungen dieser Budgetregeln auf das Wirtschaftswachstum und die Wohlfahrt einer Volkswirtschaft im Rahmen eines endogenen Wachstumsmodells mit produktiven Staatsausgaben. Hierbei werden insbesondere die Unterschiede der Fixen Defizitquote und der Goldenen Regel analysiert, die sich daraus ergeben, dass sie die Zusammensetzung der Staatsausgaben unterschiedlich beeinflussen. In den Kapiteln 6 und 7 erfolgt eine institutionelle Analyse der Budgetregeln. Es werden die bestehenden Kreditbegrenzungsregeln in Deutschland und deren Unzulänglichkeiten analysiert. Anschließend werden Reformoptionen dargestellt und deren Auswirkungen für die deutschen Bundesländer ex-post für den Zeitraum von1999-2006 quantifiziert
