Essays on the legacy of COVID-19: Economic Challenges, Migration Dynamics, and Democracy in a New Era
Full text link4.1 Million Migrants, recites a front page article of The Washington Post on June 26, 2024, referring to the number of immigration court records in the United States in the past decade. If it were the population of a city, it would the 2nd largest of the country, just after New York City. The WP is interesting because it highlights the massive shift in migration after the COVID-19 pandemic. In fact, more records were found during the 2021-2024 period than in previous years. Second, nationality-wise, the share of migrants from Central America and Mexico have dwindled; giving raise to migrants that increasingly come from farther away places, like Haiti, or even China. And third, it highlights the indelible liaison that exists between migration and current politics.
How exactly do these issues talk to each other? This dissertation examines the intersection of these phenomena through three distinct studies. In summary, first, we find that the Covid-19 infection was detrimental for household finances in developed economies. And in many cases, these issues have continued to persist until present day. Second, we find that there is a connection between hunger and migration during the pandemic, mean- ing that heightened food insecurity might be correlated with the current migrant waves in the Southern US border. And third, given the growing political importance of migrants in host countries, we find that populist govern- ments may experience a backlash stemming from these very groups. In particular, we see that, under certain circumstances, migrant groups react against anti-immigrant rhetoric by becoming citizens and actively participating in democratic elections.
Our research calls for cooperative efforts on policies on disaster preparedness, food security and migration. The papers presented in this dissertation turn our attention to the lingering impact of COVID-induced poverty and hunger on migration intentions, shedding light on the evolving nature of migration patterns in the face of new crises like inflation and climate change. By this logic, we invite concerted efforts from governments, international actors, and non-governmental organizations to invest in preparedness to tackle the threat of food insecurity arising from future shocks. These efforts, besides their normative nature, could be key instruments in mitigating issues deriving from poverty-driven migration
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
