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
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
Capital Inflows and National Debt
Full text linkUsing a three-gap model, this paper simulates the future time
paths of resource deficits in Pakistan. The paper then show that the
policy of increasing the rate of return on foreign capital can reduce
foreign debt when foreign capital is sufficiently responsive to changes
in its rate of return. This, however, happens at the expense of
increasing domestic debt. The policy of selling public assets abroad
appears fruitless. The main benefit of this policy is a reduction in
domestic debt which can better be achieved by selling public assets
domestically
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
Consumption and work hours in life cycle models with uncertain lifetimes: an individual analysis and an equillibrium analysis with overlapping generations
No full textThis thesis consists of two parts. In the first part, life cycle patterns of consumption, work hours, savings and assets of an individual under uncertain lifetimes with actuarially fair life insurance and annuities are studied and the effects on consumption and work hours of changes in survival probabilities, the age specific wage rates and the rate at interest are analyzed. A substitutability relation between consumption and leisure and the availability of actuarially fair annuities can explain the lack of decumulation even after retirement. The marginal saving rate out of anticipated labour income is positive. Under certain conditions, the marginal consumption rate could also be positive. Thus the Keynesian absolute Income hypothesis may be fully supported in the life cycle context. A general increase in survival rates creates only a wealth effect by changing the actuarially fair rates of interest. The resulting intertemporal substitution effect is offset by a change in discount factors applied to the utility function due to life uncertainty. On the other hand, an increase in survival probabilities for one individual only, creates an interrtemporal substitution effect. An evolutionary increase in wage rates creates an intertemporal allocation effect by changing the relative price of expenditure (on consumption and leisure) at different ages and an intratemporal substitution effect by increasing the price of leisure relative to consumption. On the other hand, a parametric increase in wage rates creates a wealth effect, an intertemporal reallocation effect and an intratemporal substitution effect. The compensated effect of a parametric wage increase, consisting of the intratemporal substitution effect and the intertemporal reallocation effect, on work hours (consumption) is smaller (greater) than the effects of an equal evolutionary wage Increase. In the second part, a dynamic general equilibrium model based on the Samuelson-Diamond overlapping generations framework, is developed. The model is based on the standard continuous time life cycle model under life uncertainty and incorporates all the demographic aspects of overlappiog generations. The implications of morality changes for aggregate economic behaviour are discussed. A mortality change carries a reallocation effect by affecting the lifetime decision of individuals, an age redistribution effect by changing the relative size of different cohorts, and a demographic effect by changing the growth rate of population. An increase in survival rates at the young or middle (old) age will reduce (increase) the capital-labour ratio and the wage rate and increase (decrease) the rate of interest.Doctor of Philosophy (PhD
