The news model of asset price determination: An empirical examination of the Danish football club Brøndby IF
Get PDFAccording to the news model of asset price determination, only the unexpected component of an information should drive the stock price. We use the Danish publicly listed football club Brøndby IF to analyze how match outcome impacts the stock price. To disentangle gross news from net news, betting odd information is used to control for the expected match outcome. --news model,football industry,betting odds,stock market,market efficiency,event study
The Effects of Japanese Interventions on FX-Forecast Heterogeneity
Get PDFThis paper investigates the determinants of forecast heterogeneity in the Yen-US dollar market using a panel data set from Consensus Economics. Regardless of the particular model specification and consideration of control variables we find that exchange rate misalignments increase forecast dispersion, while foreign exchange intervention of the Japanese Ministry of Finance dampens expectation heterogeneity.Exchange rates, forecast heterogeneity, survey data
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Hipótesis de la incertidumbre en el resultado en el fútbol profesional: Una revisión de alcance
No full textilustraciones, tablasThis paper reviews empirical studies that tested the Uncertainty of Outcome Hypothesis proposed by Rottenberg (1956) on the European professional football attendees. First, it reviews the theoretical aspects of the Outcome Uncertainty Hypothesis, match and championship outcome uncertainty measures, and its precedents in European football. In addition, they examine eight empirical articles selected using the scoping review model and compare them in function of shared variables and outcomes. This paper analyses research conducted in different leagues of English football, German Bundesliga, Spanish league, Serie A (Italian league), and Swiss and Austrian leagues. The analysis of this selection concluded that most studies reject the hypothesis of uncertainty of match outcomes and accept the uncertainty of championship outcomes. However, it does not represent a generalisable
conclusion due to the sample size.Este artículo revisa los estudios empíricos que pusieron a prueba la hipótesis de la incertidumbre en el resultado propuesta por Rottenberg (1956) en los asistentes al fútbol profesional europeo. En primer lugar, se revisan los aspectos teóricos de la hipótesis de incertidumbre en el resultado, las medidas de incertidumbre de resultados de partidos y campeonatos, y sus precedentes en el fútbol europeo. Además, se examinan ocho artículos empíricos seleccionados mediante el modelo de revisión del alcance y se comparan en función de las variables y los resultados compartidos. Este trabajo analiza las investigaciones realizadas en diferentes ligas del fútbol inglés, la Bundesliga alemana, la liga española, la Serie A (liga italiana) y las ligas suiza y austriaca. El análisis de esta selección concluyó que la mayoría de los estudios rechazan la hipótesis de la incertidumbre de los resultados de los partidos y aceptan la incertidumbre de los resultados del campeonato. Sin embargo, no representa una conclusión generalizable debido al tamaño de la muestra.Programa de doble titulación Universidad Nacional de Colombia

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
Hipótesis de la incertidumbre de resultado en deportes
Get PDFEste trabajo presenta la revisión de estudios empíricos, que pusieron a prueba la Hipótesis de la Incertidumbre del Resultado propuesta por Rottenberg (1956), en diferentes deportes y con grupos particulares de espectadores. En primer lugar, se revisan los aspectos teóricos relativos a la Hipótesis de la Incertidumbre del Resultado, el equilibrio competitivo, la incertidumbre del resultado del juego, los determinantes de la asistencia a los deportes, entre otros. Además, considera siete artículos empíricos seleccionados críticamente y los compara en función de variables y resultados compartidos. Este trabajo explora investigaciones realizadas en la Liga Nacional de Hockey, el fútbol alemán, el béisbol coreano, la Major League Soccer, el fútbol holandés y el críquet. El análisis de esta selección concluye con que la mayoría de los estudios rechazan la Hipótesis de la Incertidumbre del Resultado, aunque no represente una conclusión sólida debido a la diversidad de deportes y grupos analizados (Texto tomado de la fuente).This work presents the revision of empirical studies, which tested the Uncertainty of
Outcome Hypothesis proposed by Rottenberg (1956), in different sports and with particular
groups of spectators. First, it reviews the theoretical aspects concerning the Uncertainty of
Outcome Hypothesis, competitive balance, game outcome uncertainty, determinants of
sports attendance, among others. Furthermore, it considers seven critically selected
empirical articles and compares them based on shared variables and results. This work
explores research done in the National Hockey League, German soccer, Korean baseball,
Major League Soccer, Dutch soccer, and cricket. The analysis of this selection concluded
with most of the studies rejecting the Uncertainty of Outcome Hypothesis, even though it
does not represent a solid conclusion due to the diversity of sports and groups analyzed.MaestríaMagíster en Administració
