Academic and non-Academic Investments at University: the Role of Expectations, Preferences and Constraints
Full text linkThis paper estimates a discrete choice model of time allocation decisions made by university students. We consider investments in academic and non-academic activities, such as job placements or volunteering. Identification is achieved using data collected through a recent survey of UK university students on subjective expectations about the returns to these activities, and the enjoyment students derive from them. Unobserved heterogeneity in the choice set is addressed using a sufficient set logit method. The analysis reveals significant ethnic differences in the level of investments, expected academic and labour market returns, and enjoyment of academic and non-academic activities. Simulations suggest that existing constraints play an important role in explaining ethnic gaps in investments
Eseje v Oblasti Experimentální Ekonomie: Diskriminace a Vzdělání
Full text linkCERGE Center for Economic Research and Graduate Education Charles University Essays in Experimental Economics: Discrimination and Education Nikoloz Kudashvili Dissertation Prague, August 2022 Abstract In the first chapter, I study the sources of discrimination. Preference-based discrimination is usually deep-seated and takes a long time to be dealt with. By contrast, statistical discrimination can be eliminated or reduced in a relatively shorter period. The latter type of discrimination is based on stereotypes, which can be overcome by providing relevant information. I conduct a field experiment to measure the extent and nature of discrimination in the Georgian land market. The experiment is designed to uncover sources of statistical discrimination due to different beliefs about foreign investors. Discrimination is measured by the difference in price offers to foreign and Georgian investors. I find that the magnitude of discrimination shrinks significantly once foreign investors signal their willingness to search and pay the lease price in advance. This suggests that discrimination is largely driven by stereotypes about search costs and the payment reliability of foreign investors - leaving no or very little preference-based discrimination. Knowing the source of discrimination can be helpful to policy...CERGE Center for Economic Research and Graduate Education Charles University Eseje v Oblasti Experimentální Ekonomie: Diskriminace a Vzdělání Nikoloz Kudashvili Disertační práce Praha, Srpen 2022 Abstrakt V první kapitole tržní diskriminace je dobře zdokumentována empirickými studiemi. Field experimenty jsou naproti tomu méně úspěšné při identifikaci zdrojů diskriminace. Tento článek předkládá experimentální důkazy o rozsahu a povaze diskriminace na trhu s pozemky v Gruzii. Cílem experimentu je odhalit možné zdroje statistické diskriminace v důsledku rozdílných názorů na zahraniční investory. Diskriminace je měřena rozdílnými cenami pro domácí a zahraniční investory. Zjistili jsme, že síla diskriminace významně klesá s ochotou zahraničních investor důkladněji prozkoumat trh a platit nájem předem. To naznačuje, že diskriminace je ovlivněna především stereotypy o nákladech na průzkum trhu a schopnosti zahraničních investorů platit nájem předem. Vliv diskriminace na základě preferencí mezi zahraničními a domácími investory se zdá být zanedbatelný. Znalost původu diskriminace může být užitečná při tvorbě antidiskriminačních zákonů. V druhé kapitole diskriminace vůči menšinám je přítomna v mnoha společenských skupinách, ale málo se ví o strategiích, které mohou menšiny použít k minimalizaci diskriminace....CERGEFaculty of Social SciencesFakulta sociálních vě
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
