Essays on the Economics of Inequality in Hydrological Systems
This dissertation examines how water scarcity and environmental change interact with human-made systems to generate unequal outcomes. In California, I show that drought conditions intensify agricultural groundwater pumping, increasing drawdown of contaminants into groundwater supplies. Where adaptive capacity is unequal, this response can worsen environmental inequality: Latino/a communities face increased drinking water contamination during dry periods as a result, driven by disparities in drinking water infrastructure. I then assess how regulatory design to correct groundwater overpumping can shape agricultural production, employment, and social equity. Using a structural model calibrated with farm-level data, I compare market-based and proportional groundwater cutbacks mandated under the Sustainable Groundwater Management Act (SGMA). I find that markets increase farm profits and employment but cause the exit of small farms, leading to increased consolidation. Gains are largely driven by locations with high crop diversity. Finally, I turn to the global scale, quantifying economic dependencies on atmospheric moisture recycling – a critical yet underrecognized component of the hydrological cycle. Current patterns of human settlement imply that future deforestation will disproportionately disrupt rainfall in low-income, inland regions that depend on rainfed agriculture the most – revealing an understudied dimension of climate risk. Together, these studies demonstrate that both environmental change and policy design can deepen socioeconomic disparities unless equity is explicitly considered
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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

The economics of environmental change: Essays on climate and water
Many questions of importance for sustained human progress on a planet of finite resources remain unanswered. As environmental change accelerates, there is growing urgency to build an understanding of how the environment and society influence one another. This dissertation mobilizes novel, large-scale datasets in combination with methodological advances in casual inference and original theoretical contributions to study the interdependence between societies, economies, and two of the world's most vital natural endowments: the climate and freshwater. Throughout these essays, I estimate causal, policy-relevant relationships between global-scale processes of environmental change and human wellbeing. The first three essays provide new estimates of the climate's influence over market and non-market outcomes, generating insights in climate impact attribution, climate impact mechanisms, and the estimation of adaptation costs and benefits under anthropogenic climate change. The final essay studies the other direction of the society-environment relationship, measuring how changes in economic systems influence freshwater. This chapter uses satellite data to uncover links between agricultural policies and water depletion at a scale that has been impossible to investigate with standard water monitoring tools. Together, these essays aim to demonstrate that combination of data and methods across physical and social sciences can yield valuable answers to questions that have been discussed, debated, and left unresolved for generations
Dispelling the Myths Behind First-author Citation Counts
We 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
