Heterogeneous Effects of Commodity Price Shocks on Inflation Rates. Evidence from a Panel Study.
Get PDFDo commodity price shocks have heterogeneous effect on countries based on their export and import profiles? I address this question through a panel study of 142 countries using Export and Import Indexes aimed at differentiating the retail pass-through and fiscal balance channel of transmission of Commodity Price shocks on inflation. The results show that an increase in the Export Index leads to a decrease in contemporary inflation while an increase in the Import Index leads to an increase in inflation in the next year. Average causal mediating effect of the Export Index on Inflation through the Fiscal Balance was shown to be negative
Impact evaluation of support to collective action for agricultural value chain development in Nepal
No full textMatching grant programs administered to agricultural groups and cooperatives have emerged as a means of helping smallholder farmers to commercialize in Nepal. These programs help farmers to access information on new technologies, overcome barriers to productive investment, and connect with output markets, although the combinations of support received by individual households vary. This study disentangles the causal effects of different elements of support through an inverse probability weighted two-way fixed effects analysis of data from a panel of 2,268 households, of which 47% belong to 246 farmer groups in three provinces. It finds that group membership without receiving support has important effects on commercialization and income, as does receiving any support. The forms of support with largest effects on production, income, and/or human capital include production training, marketing support, and a combination including both training and assets. In contrast, only modest or even negative effects are detected from provision of either inputs or credit in isolation
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
Intrahousehold responses to imbalanced human capital subsidies: Evidence from the Philippine conditional cash transfer program
No full textExtensive global evidence suggests that conditional cash transfers (CCTs) encourage long-term investment in human capital by poor households. However, CCTs also have the potential to distort incentives for investment among children. If only some children in the household are monitored/subsidized for compliance with conditionalities, returns to household investment in those children increase relative to siblings who are unmonitored/unsubsidized. This paper demonstrates that puzzling nutrition effects of the Philippine CCT are driven by effects on children unmonitored for educational compliance, due to a cap of monitoring at most three children per household. Regression discontinuity design interacted with a secondary instrument for monitoring finds that while monitored children have improved human capital investment, such investment declines for unmonitored children relative to nonbeneficiaries. Patterns are consistent for parental expectations, health, anthropometric, and educational outcomes, and are stronger for boys, in accordance with theoretical expectations. Equalized incentives among children can enhance intended CCT effects
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
