Three Essays on the Foundations of Public Policy Making
Full text linkÜber die letzten zwölf Jahre sind globale Indikatoren für Demokratie- und Freiheitsrechte kontinuierlich gesunken. Demokratie ist eine wichtige Triebkraft für wirtschaftliche Entwicklung, daher folgen aus diesem Vertrauensverlust auch Sorgen über die Zukunft des ökonomischen Wohlstandes. Diese Dissertation besteht aus drei Essays und untersucht mögliche Reformen für effektivere politische Gestaltungsmöglichkeiten in demokratischen Systemen: Dezentralisierung und Privatisierung.
Das erste Essay überprüft, ob durch Dezentralisierung der öffentlichen Arbeitsvermittlung mehr Arbeitslose in freie Stellen vermittelt werden können. Dafür untersuche ich die Kommunalisierung deutscher Jobcenter im Jahr 2012. Dabei stelle ich fest, dass sich durch Dezentralisierung die Neuanstellung von Arbeitslosen um rund 10% verringern. Es zeigt sich, dass dezentralisierte Arbeitsvermittlungen vermehrt öffentlich geförderte Arbeitsbeschaffungsmaßnahmen nutzen.
Das zweite Essay beschäftigt sich mit finanzpolitischen Wechselwirkungen zwischen Gemeinden in Kolumbien, wo die Verantwortlichkeit für einen großen Teil des Staatsbudgets an die kommunale Regierungsebene übertragen wurde. Es ergeben sich starke räumliche Autokorrelationen im lokalen Ausgabeverhalten. Allerdings zeigt sich durch einen Instrumentalvariablenansatz, dass es keine kausalen fiskalischen Interaktionseffekte zwischen den Gemeinden gibt.
Das dritte Essay analysiert, ob Regierungen ökonomischen Effizienzüberlegungen folgen, wenn sie entscheiden, welche staatlichen Firmen für eine Privatisierung ausgewählt werden. Basierend auf der Massenprivatisierung in Folge des Falls der Berliner Mauer untersuche ich Firmendaten, welche mehr als 6.000 Privatisierungs- und Liquidationsentscheidungen umfassen. Die Ergebnisse legen nahe, dass Privatisierungsentscheidungen weniger politisch, sondern stärker ökonomisch orientiert sind, als dies durch bisherige Studien bekannt ist.Global indicators of democracy and civil liberties have continually decreased over the past twelve years. Scholars have identified weak public policy-making as an origin for low levels of trust in democratic governance. In three essays, this dissertation studies two reform options to improve policy-making, namely decentralization and privatization.
The first essay examines whether the decentralization of public employment services (PES) increases job placements among the unemployed. Using a difference-in-differences design, I exploit unique within-country variation in decentralization provided by the partial devolution of German job centers in 2012. I find that de-centralization reduces job placements by approximately 10% while expanding the use of inefficient public job creation schemes.
Essay two explores fiscal interactions in Colombia, a developing country which shifted the responsibility for a large share of public spending from the central to local governments. I find evidence of strong spatial autocorrelation of local public spending. However, an instrumental variable approach reveals that there are no significant causal fiscal interaction effects between municipalities.
The third essay studies whether governments incorporate economic efficiency considerations when choosing which firms they select for privatization. Analyzing mass privatizations following the Fall of the Berlin Wall in Germany, I employ previously unavailable firm data on more than 6,000 privatization and liquidation decisions. The analysis suggests that privatization decisions are less politicized and more efficiency-oriented than found in previous studies
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
Jobcenter: Optionskommunen vermitteln Arbeitslose seltener in Beschäftigung
No full textDie Jobcenter in Deutschland werden entweder als "gemeinsame Einrichtungen" von Kommunen und der lokalen Agentur für Arbeit oder in "Optionskommunen" allein von den Kommunen geführt. Die Umwandlung von 41 gemeinsamen Einrichtungen in Optionskommunen im Jahr 2012 erlaubt es, den Erfolg der Vermittlungsarbeit der beiden Trägerformen zu evaluieren. Die Analyse zeigt, dass Optionskommunen gegenüber gemeinsamen Einrichtungen 10% weniger Arbeitslose in den ersten Arbeitsmarkt vermitteln. Hingegen weisen sie mehr Personen "Ein-Euro-Jobs" zu, die jedoch wenig geeignet sind, die Übergangschancen in den ersten Arbeitsmarkt zu erhöhen
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
Integrationsperspektive von ukrainischen Geflüchteten im deutschen Schulsystem
No full textDer anhaltende Angriffskrieg in der Ukraine stellt Deutschland vor die Frage, wie es die ukrainischen Geflüchteten bestmöglich unterstützen kann. Der hohe Anteil geflüchteter Schulkinder rückt dabei die Frage nach Schulbildung in den Fokus. Diese ist essenziell sowohl für eine gelingende Integration in Deutschland als auch für die Rückkehr in ihr Heimatland. Eine Auswertung der PISA-Studie 2018 zeigt, dass ukrainische Schulkinder in einem standardisierten Test unter dem Niveau von deutschen Schulkindern abschneiden, insbesondere in Mathematik. Die Leistungen liegen jedoch deutlich über denen der EU-Mitgliedstaaten Bulgarien und Rumänien, aus denen bereits zahlreiche Kinder in das deutsche Schulsystem integriert wurden
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
