Political Islam, Internet Use and Willingness to Migrate: Evidence from the Arab Barometer
Full text linkThis paper investigates the relationship between political Islam, willingness to migrate and Internet use by exploiting the second (2010-2011) and the third (2012-2014) waves of the Arab Barometer. In an effort to explain individual-level willingness to migrate from the Arab world, it investigates the channel through which the more people support political Islam the less they are willing to migrate. At the same time, it explores the fact that the Internet could potentially act as a vehicle of political Islam. Indeed, our findings indicate that there exists a positive relationship between Internet use and individual-level willingness to migrate, while there exists a negative relationship between political Islam and individual-level willingness to migrate. The findings indicate also that there is no significant effect of Internet use on political Islam
What exactly is public in a public good game? A lab-in-the field experiment
No full textAre public good games really capturing individuals’ willingness to contribute to real-life public goods? To answer this question, we conducted a lab-in-the-field experiment with communities who own collective goods. In our experiment, subjects voluntarily contribute to a common pool, which can either be subdivided in individual vouchers, as in standard public good games, or used to acquire collective goods, as it happens for real-life public goods. We show that participants’ contributions are larger when the voucher is paid individually, suggesting that individuals’ willingness to contribute to public goods may be overestimated when based on results from laboratory experiments
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
The Less Extreme, the More You Leave: Radical Islam and Willingness to Migrate
Full text linkThis paper studies radical Islam as a determinant of individuals’ willingness to migrate. Surprisingly, despite its relevance in the political debate, this topic has not been investigated empirically in the literature. In order to fill this gap, we develop a model of the decision to migrate focusing in particular on the role played by cultural traits. More specifically, we focus on radical Islam as a deterrent for migration. Following Berman (2003), we define radical Islam as a set of ideologies, also referred to as Political Islam, holding that Islam should guide not only personal life, but also social and political life. In our model, more radical values imply a higher psychological cost of migrating. This cost derives from the fact that connections with socio-religious friends and neighbors are generally not maintained after migration, thus deterring individuals from migrating (Mayers, 2000). We then test empirically the predictions of the model, using individual-level data from the second (2010–11) and third (2012–14) waves of the Arab Barometer. Our results suggest that, ceteris paribus, more radical individuals are less willing to migrate. This finding is robust to alternative specifications of the model and to the use of Instrumental Variables and Propensity Score Matching aimed at addressing the potential endogeneity of radical Islam. The result is also qualitatively unchanged when using aggregate data on actual outflows of migrants
Investment, insurance and weather shocks: Evidence from Cambodia
Full text linkThe livelihoods of poor people in developing countries are increasingly dependent on weather shocks whose effects are exacerbated by the lack of access to adequate insurance markets allowing risk hedging. Index-based insurance underwrites a weather risk as a proxy for economic loss: when the index falls below a certain level, farmers automatically get a payment. The aim of this paper is to study the impact of an Index-based insurance on investment decisions in profitable but risky inputs in presence of weather shocks by means of an incentivized lab-in-the-field experiment conducted in Cambodia. The protocol is designed so as to study the extent to which investment decisions change under risk or ambiguity, for different levels of initial wealth, under contract nonperformance (i.e., when claims are not repaid by the insurer) and when the insurance is fully subsidized. The findings indicate that, while the mere presence of a market for insurance increases investment, the strength of the effect crucially depends upon the level of initial wealth and upon the subjects' ability to correctly assess the probability of a shock
MNEs as catalysts of productive entrepreneurship: the case of Egypt
No full textForeign direct investments (FDI) towards developing economies have grown to such an extent that
today, among the top ten FDI recipients in the world, five are developing economies (UNCTAD,
World Investment Report, 2020). Economics and management literature has long recognized that,
under certain circumstances, multinational enterprises (MNEs) play a crucial role in fostering local
economic development. While some scholars have shown optimism regarding the impact of MNEs
on developing countries (see, among others, Caves, 1974; Teece, 1977; Anwar & Nguyen, 2011),
others have proven to be skeptical (see, among others, De Backer & Sleuwagen, 2003; Haddad &
Harrison, 1993; Agosin & Machado, 2005). Despite the inconclusiveness of literature, the 2030
Agenda of the United Nations assigns a special role to MNEs for local economic development when
it states that “private business activity, investment and innovation are major drivers of productivity,
inclusive economic growth and job creation,” and calls upon MNEs, along with other businesses, “to
apply their creativity and innovation to solving sustainable development challenges.
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
