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
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
¿Contribuye la globalización a la disminución de las tasas de trabajo infantil?
Get PDFThis study examines the relationship between globalization (from a multidimensional
viewpoint) and child labor. No specific a priori relationship was
found through an analysis of the impact of globalization on child labor in relation
to a country’s level of development. The use of panel data methodology
reveals empirical evidence of an inverted U-shaped relationship between globalization
and child labor in countries with medium-low and low incomes. The
inflection point and the convergence coefficient obtained, describe the nature
of the social phenomenon - child labor - in low-income countriesEste estudio examina la relación entre la globalización (desde un punto de
vista multidimensional) y el trabajo infantil. Se evalúa el impacto de la globalización
sobre el trabajo infantil en relación al nivel de desarrollo de los países.
El análisis muestra que no hay una relación determinada a priori entre globalización
y trabajo infantil teniendo en cuenta el nivel de desarrollo. El uso de la
metodología de datos de panel revela la existencia de una curva U-invertida
entre globalización y trabajo infantil en países con ingresos medios y mediosbajos.
El punto de inflexión y el coeficiente de convergencia que se obtiene,
muestra como éste fenómeno social del trabajo infantil se presenta en países
de bajos ingreso
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
Journal of Business Economics and Management
No full textThe objective of this work is to analyse firm mobility among the different sectors of the Spanish economy according to a statistical classification of economic activities at the 1-digit level. Some of the stylised facts that we find are: an inverse relation between firm growth and age; an increase in new entrants' average relative size in terms of sales compared to established firms among the different industries and cohorts; the importance of the firm's initial size in entrepreneurial activity; the favourable impact of the economy on firm growth; and a positive relation between non-concentration in the ownership structure and greater mobility. In this context, an efficient corporate governance system may prove as a significant policy tool for the investment and growth prospective of the Spanish economy. The regulatory framework of the Spaniard capital market has been coordinate with the EU standards. The challenge is now mostly for the firms to adopt the appropriate corporate governance structures, in order to achieve real convergence, in terms of productivity and competitiveness, with other developed economies
Factores condicionantes de la relación entre la cuota relativa de mercado y el ROI : evidencia empírica en el sector manufacturero español
Get PDFEn este trabajo se sugiere la existencia de una relación en forma convexa entre el\ud
ROI (Return On Investment) y la cuota relativa de mercado (en adelante CM) para\ud
el conjunto de los sectores que conforman las empresas manufactureras españolas, a\ud
partir de los datos recopilados por la ESEE en el periodo comprendido entre 1993-\ud
1998. Los resultados obtenidos parecen indicar que las empresas se encuentra en la\ud
zona creciente de la curva que define la relación entre el ROI y la CM. El 70% de\ud
las empresas de la muestra se encuentran en la zona positiva frente al 30% que están\ud
en la zona negativa. Esto podría sugerir que dadas las características de las\ud
empresas, estas necesitan de un período de recuperación amplio, de forma que\ud
inicialmente las empresas invierten en ganar cuota de mercado para posteriormente\ud
incrementar su rentabilidad. Los diferentes modelos planteados incorporan una\ud
serie de variables mediadoras que representan una serie de potenciales estratégicos\ud
susceptibles de condicionar la citada relación entre el ROI y la CM y que siguiendo\ud
a Johnson y Sholes (2000) pueden clasificarse en: fortalezas competitivas, atractivo\ud
del mercado, producción ajustada y prácticas de recursos humanos. Por último, el\ud
trabajo pretende incorporar una variable moderadora representada por el nivel\ud
tecnológico de las empresas a partir de la clasificación introducida por Segura et al.\ud
(1989), que pudiera modular las relaciones previamente analizadas.In this work, the existence of a relation in convex form between ROI and the relative\ud
quota of the market (hereafter CM) is suggested for the group of those sectors\ud
formed by Spanish manufacturing businesses, based on data obtained from the ESEE\ud
in the period 1993-1998. The results obtained seem to indicate that the firms belong\ud
to the growth zone of the curve defining the relation between ROI and the CM. 70\ud
per cent of the firms in the sample are in the positive side meanwhile 30 per cent of\ud
them are in the negative side. This could suggest that given the characteristics of the\ud
firms, they require a wide period of recuperation as the businesses invest initially in\ud
a large quota of the market in order to later increase their return on investment. The\ud
different models proposed incorporate a series of mediating variables which\ud
represent a series of strategic potentials able to condition the aforementioned\ud
relation between ROI and the CM and which according to Johnson and Sholes\ud
(2000) could be classified in; competitive fortresses, market attraction, controlled\ud
production and human resources practises. Finally, the work endeavours to\ud
incorporate a moderating variable represented by the technological level of the firms\ud
as established by the classification introduced Segura et al. (1989) which could\ud
modulate the relations previously analysed
