    The effect of a new sports facility on property development: Evidence from building permits and a localized synthetic control

    A leading edge of sports economics research over the last decade has been the impact of sports facilities on property prices. While there is near consensus of positive, distance-decaying price effects, the existing literature has yet to begin exploring the underlying causal mechanism of the price response. One possible mechanism is increases in building quality. This study tests for a sports-induced change in building quality as measured by building permits in census tracts in Sacramento, California, where a new arena for a professional basketball franchise opened in 2016. The identication strategy is a localized synthetic control where localization restricts the donor pool to census tracts in the city limits in order to hold building codes and permit administration constant over time. Baseline models and multiple robustness checks indicate the arena had no effect on permit activity

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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

Amongst the revenue-raising proposals under consideration is an expansion of the sales tax base to include services. Due to a paucity of research on the subject, policymakers tend to use crude estimates of the additional revenue that could be raised by taxing services. This thesis is an attempt to ground and refine these estimates. I compiled a panel data set of sales and use tax revenue for 43 states over a period of 15 years in order to capture revenue fluctuations across multiple business cycles. To investigate the relationship between sales tax base and revenue, I used service base data available from the Federation of Tax Administrators and adjusted it to reflect the relative market size of each service industry in each represented state. Additionally, I controlled for a host of state-specific factors including, though not limited to, sales and use tax rate, household population, racial demographics, and per capita disposable income. For the econometric analysis, I employed a fixed effects regression model. There are three major findings. First, potential revenue yields vary greatly both within and across particular service base categories. For example, estimates for admission and entertainment services range from 0.6 to 7.7billion,whiletaxingtransportationservicescouldraise7.7 billion, while taxing transportation services could raise 4.8 to $20.2 billion. Second, according to an alternatives matrix calculated for California, transportation, lease and rental, and automotive services offer the best combination of political feasibility and revenue returns. Third, in the short-run, tax rate increases yield more revenue than base expansions
