Three essays on agriculture, environment and human capital formation in India
Get PDFThis dissertation present three studies related to environmental factors that may help explain early life mortality outcomes, household consumption decisions during childhood that could drive human capital development in later life, and potential market failures that affect farmers' returns in rural agricultural markets. The setting for all three studies is India where indicators of health and human development remain low, particularly in rural areas where majority of the households rely on agriculture as a primary source of livelihood.
In chapter two, I analyze the impact of exposure to air pollution on risk of early childhood mortality. I exploit variation in the incidence of agricultural fires used by farmers combined with changes in wind direction to estimate the causal impact of air pollution on infant mortality at a countrywide scale. I find that \emph{in-utero} pollution exposure increases infant mortality risk by more than six percent, with the mortality burden being higher among rural households and the urban poor.
In chapter three, I examine whether informal contracts provide incentives for improving product quality in agricultural markets. Using a novel field experiment, we show that farmers receive only \$0.80 for a potential \$1 payoff for improved grain quality. However, we also find that social connections between a farmer and a trader improve the farmer’s payoff for quality suggesting that informal, long-term relational contracts can provide incentives for investing in product quality.
Finally, in chapter four, I examine the unintended consequences of regulating addictive consumption on intergenerational human capital transmission using evidence from alcohol prohibition laws in India. I use the variation in “partial” alcohol bans that prohibited sale and consumption of cheaper varieties of alcohol across states in India. I show that households exposed to these partial alcohol bans shift consumption expenditure towards costlier alcohol and reduce private investment on health and education of children. In the long term, this results in an average reduction in the years of schooling among children who were exposed to these bans of more than four percent compared to the sample mean.Submission original under an indefinite embargo labeled 'Open Access'.

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
Supply and demand for cereals in Nepal, 2010–2030:
Get PDFThis paper attempts to estimate the future supply and demand for cereals in Nepal. While there has been considerable research in the past examining the agricultural sector in Nepal, to the best of our knowledge there has been no analysis of the supply-demand scenario for food grains in the country. The analysis undertaken in this paper attempts to bridge this gap in the literature by estimating supply and demand models for the three most important cereals in Nepal's food basket: rice, wheat, and maize. The supply projections have been carried out on the basis of a single-crop production function model using data for the period 1995–2008. For estimating the demand function and projecting future demand, data from the Nepal Living Standards Survey II (NLSS II), undertaken in the year 2003/04, are used.cereal supply, cereal demand,
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
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
