Essays in Environmental Economics: Exploring the Effects of Extreme Events
Full text linkWildfires are destructive and are expected to become more costly and impact more people in the future. This dissertation investigates how wildfires impact people's migration decisions, the financial consequences of these disasters, and the impact of government aid in three chapters. The first chapter evaluates adaptive migration -- the movement from risky to safe areas -- as a potential adaptation strategy. Granular, address-level credit and migration data are combined with wildfire and risk measures to trace residents’ locations over time, before and after the fire. The empirical strategy leverages the quasi-random trajectory of the wildfire. The results indicate that people living in blocks that burned for the first time are 6.5 p.p. (18.5\%) more likely to remain away, even after four years. Although migration initially leads to safe tracts after two years, this effect vanishes by the fourth year. When focusing on financially unconstrained subgroups, people are statistically significantly more likely to be in safe areas, suggesting that financial constraints may prevent adaptive migration.The second chapter assesses how experiencing a megafire -- a fire that burns over 100,000 acres -- affects an individual's household finances and neighborhood decision. There is evidence of financial distress: credit scores fall and active debt collections rise. Moreover, the likelihood of having a mortgage drops by 5.3 points (19.7 percent) at two years and remains 3.0 points (10.6 percent) lower at four years. Examining the characteristics of their destinations, impacted individuals settle in areas with higher amenities, though they are also more expensive.The third chapter evaluates the Federal Emergency Management Agency (FEMA)’s Individuals and Households Program (IHP). Using political competitiveness as an instrument for aid receipt, I find that IHP increases migration by 33.0 p.p. yet does not improve migration to safe areas, unsurprising given its non-targeted design. Aid recipients experience substantially less financial distress and greater credit access, underscoring IHP’s role in alleviating immediate hardship even as it falls short of promoting adaptive migration. Together, these findings highlight financial barriers to climate-driven adaptation and suggest policy changes to align disaster relief with long-term resilience
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
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
