Immigration amnesties in the southern EU member states - a challenge for the entire EU?
Full text linkThe question of how to proceed with illegal immigrants arriving in the southern EU member states is one of the pressing policy issues for the EU. In our article we will provide a thorough analysis of immigration policy and immigration amnesties from an economist’s perspective. In particular, we are interested in answering questions such as why (at all) some states legalize irregular immigrants and what effects unilateral policy measures in this field have in an economic union such as the EU. While most of the work in the area of immigration amnesties focuses on the single country case we extend this scenario to the case in which the legalizing country is part of a federation and spillover effects between different states may occur. Several interesting aspects will be considered in this context, in particular, potential changes of the policy mix between internal and external enforcement on the one hand and legalization on the other hand when a federal setting is considered instead of a single country.illegal migration, immigration policy, regularization, amnesties, enforcement, interregional transfers, European Union
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
Public pensions and immigration policy when voters are differently skilled
Full text linkAlthough immigration of workers generates a positive externality on members of domestic pension systems, many countries are very reluctant to allow foreigners into their labor markets. In a political economic framework, we explain this voting outcome by considering a young unskilled median voter who faces – in addition to a reduction of contribution rates – negative effects from immigration as well. --pensions,immigration,median voter,skill differences
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
