    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

    Does changing the timing of a yearly individual tax refund change the amount spent vs. saved?

    The empirical evidence surrounding whether federal income tax refunds predominantly stimulate consumer spending or saving remains contradictory. This study is an attempt to combine income tax research findings with research on mental accounting and with the effects of estimated tax payments timing. The authors developed and administered an experiment, using college students as subjects, to test whether tax refunds administered as one lump-sum will be saved (vs. spent) more than tax refunds of the same amount refunded monthly through revised income tax withholding tables. The study also explores the types of saving and spending that result from refunds under both timing patterns. A within subjects experiment of student spending was used, and ANOVA results confirm that a refund delivered in monthly amounts (for example, by changing the federal income tax withholding tables) stimulated current spending more than if the same yearly total tax reduction was delivered in one lump-sum. The findings also suggest that the lump-sum distribution conversely will stimulate private saving more than a monthly distribution will. The study also explores other specific savings and spending tendencies, including the payment of credit cards vs. investments in securities, and the amount spent on durable goods vs. monthly expenditures across several monthly and yearly distributions. It is important to know if and how the timing of refunds affects savings and spending tendencies because tax cuts are often debated on the political stage as a means to stimulate spending, and the timing of the refund might change how effectively a tax cut meets that goal.Decision making Consumer behavior Economics Mental accounting Tax

    Maximizing Ponzi Loss Deductions for Estate and Income Tax Purposes: Are Taxpayers Better Off Dead?

    There is a long history of cases interpreting whether a theft loss deduction for securities fraud is allowable for personal income taxes. The cases require that for a theft loss to be actionable as such, it would have to meet the requirements of the common law definition of theft in the U.S. state in which it occurred. This generally requires direct privity between the person claiming the loss and the person who committed the theft. Because most securities transactions are brokered, the direct privity is lost and a theft loss deduction is denied in favor a capital loss. Recently, in a case of first impression, the Tax Court was presented with a similar issue involving the worth of assets for estate taxes. Instead of using the reasoning presented in income tax cases, the Tax Court allowed a theft loss deduction on estate taxes where a Ponzi scheme was uncovered while the estate owned a limited liability company. The sole assets of the company were shares of the security that was involved in the Ponzi scheme. This Article examines the history of the privity requirement for deducting a theft loss for income taxes and how that reasoning now differs from the tax treatment for estate taxes. The Article concludes that there should not be a difference in treatment and that direct privity should not be required for either income or estate taxes

    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We 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
