The Impact of Education on the Subjective Discount Rate in Ugandan Villages
Full text linkHeterogeneity in time discounting may reinforce the existing barriers to save and invest faced by rural populations in developing countries. We elicit a subjective discount rate for a varied sample of Ugandan villagers. In accordance with other studies, we have found the discount rate to decrease with education. We examine this correlation further by testing the causal effect of education and exploit two different sources of its variation: school frequency across villages and the number of the respondents' school-going years that overlap with the era of the dictator Idi Amin's rule. For men, we find that education has a significant impact on their discount rate, similar in magnitude for both types of instruments and robust to observable characteristics. This finding highlights the importance of education in development.patience, education, time discounting, economic development, Uganda
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
Women, Children and Patience: Experimental Evidence from Indian Villages
Full text linkIn this paper we study the link between women's responsibility for children and their preferences. We use a large random sample of individuals living in rural India, incentive compatible measures of patience and risk aversion, and detailed survey data. We find more patient choices among women who have a higher number of children. The age of children matters: The link with patience is specific for children below 18 years old, and the highest level of patience is associated with having three children. We do not observe this link among men. Taken together, we find significant gender differences in patience that are predicted by a higher number of children. The results are robust to controlling for age, education, income constraints, and individual and location characteristics. These findings suggest an important context when the spending preferences of spouses diverge, and support the view that empowering women in developing countries should lead to more future-oriented choices of households.time discounting, gender, children, experiment, India
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
Income Shocks and Ethnic Group Bias
No full textDiploma Thesis Abstract JEL Classification Z13, O12, O13, Z91 Keywords income shock, endogeneity, ethnicity, instrumental variables Title Income Shocks and Ethnic Group Bias Author's e-mail [email protected] Supervisor's e-mail [email protected] Abstract The thesis explores how individual income shocks impact ethnic group bias using a survey dataset from Uganda and meteorological data. Previous research has shown that the majority of civil conflicts break down along ethnic lines, and that ethnic tribalism harms economic performance of countries. A better understanding of the causal mechanism behind ethnic bias could help alleviate both of those problems. The author finds that income shocks have no measurable effect on ethnic out-group bias, but they might influence ethnic in-group bias. Since the regression of ethnic bias variables on income proxies likely suffers from endogeneity, the author employs the copula endogeneity correction model, which, however, does not prove to perform well with a binary dependent variable. In addition, the author demonstrates that ethnic group bias is most likely not directly influenced by variations in rainfall and that instrumenting for income with rainfall variation leads to non- robust results with even a small violations of model assumptions
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
