Changing households'investments and aspirations through social interactions : evidence from a randomized transfer program
Get PDFLow aspirations can limit households’ investments and contribute to sustained poverty. Vice versa, increased aspirations can lead to investment and upward mobility. Yet how aspirations are formed is not always well understood. This paper analyzes the role of social interactions in determining aspirations in the context of a program aimed at increasing households'investments. The causal effect of social interactions is identified through the randomized assignment of leaders and other beneficiaries to three different interventions within each treatment community. Social interactions are found to affect households’ attitudes toward the future and to amplify program impacts on investments in human capital and productive activities. The empirical evidence indicates that communication with motivated and successful nearby leaders can lead to higher aspirations and corresponding investment behavior.Debt Markets,Labor Policies,Investment and Investment Climate,Primary Education,Housing&Human Habitats
Risk and vulnerability considerations in poverty analysis: A short note on recent advances and research directions
No full textIn the recent past, growing attention has been devoted to the attempt to correctly include considerations
of exposure to risk in the discussions on poverty reduction and, more generally,
economic and social development. The purpose of this article is to take stock of all these efforts
and to reconsider the relationship between poverty and exposure to risk. We present a
short review of current practices of vulnerability measurement to discuss how none of them
is truly consistent with an ex-ante view of assessing the true consequences of risk exposure.
We argue that one way of addressing this inconsistency is by adding an estimate of the insurance
cost needed to guarantee a socially accepted minimum level of welfare to the level of
consumption expenditure taken as a benchmark to identify the poor. In other words, we define
an augmented poverty line where the traditional absolute poverty benchmark level is
marked up by the estimated cost of insuring against what are considered socially unacceptable
risks. We then discuss the practical implications for implementing such a measure and
future research directions
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
