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
Political Activity Limits and Tax Exemption: A Gordian’s Knot
The article considers the correct tax treatment of organized political activity by the tax system and discusses the problems that have arisen from political activity depending on whether the organization is a charity, a noncharitable exempt, or a political organization. The article then examines administrative and legislative options to the problems raised by political activity. Quantum-based solutions to the problem of political activity by noncharitable exempts do not provide a clear advantage over present law. Formally quantifying the “primarily” test would result in more certainty, but would also require that the Service be more, not less, involved in the regulation of political activity. If the policy goal is to curb political activity by noncharitable exempts, changing the test from “primarily” to something more restrictive like “substantially” or “exclusively” would be effective, but would create new categories of taxable nonprofits that are treated worse than political organizations for engaging in less political activity, which is irrational. Further, it is not clear, especially after the Citizens United decision, why as a matter of tax exemption the regulations decree that political activity may not further noncharitable exempt purposes. Before Citizens United, the political activity limits were not especially relevant, but at least helped to differentiate organization types. However, Citizens United largely rendered existing tax law limitations obsolete by making a new kind of multi-purpose organization possible. As a result, definitional political activity limits are no longer justified and should be eliminated, but only if the 527(f) tax on investment income remains vital and the differences in the disclosure regimes between political organizations and noncharitable exempts are erased. In addition, Congress should affirm that the gift tax does not apply with respect to political contributions, but also extend the income tax to transfers of appreciated property to noncharitable exempts. Further, Congress should acknowledge that the increase in political speech by noncharitable exempts will lead to abuse of charitable organizations, and take steps to prevent the laundering of independent expenditures through the charitable form. Congress also should recognize that Citizens United has led to a need to develop a new tax baseline for political activity conducted “for profit” or outside of section 527
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
Strings Are Attached: Shining a Spotlight on the Hidden Subsidy for Perpetual Donor Limits on Gifts
Charitable gifts often come with strings attached. Donors limit their gifts in many ways, typically by restricting an asset’s use or purpose, the timing of spending (as in an endowment), and by securing naming rights. Donors also limit their gifts by giving to a charitable intermediary such as a donor-advised fund or private foundation, thereby retaining effective control over the distribution or investment of the donated asset. Donor limits are perpetual in nature. This Article assesses the law of donor limits. The Article explains that non-tax legal rules strongly favor donor limits; they are easy for donors to impose and hard for charities to eliminate. Federal tax rules also favor donor limits by treating most donor-limited gifts the same as unrestricted gifts for purposes of the income and estate tax charitable deductions. As a result, donor limits are common and burden a substantial portion of charitable assets. The Article finds based on a review of Form 990 data that, for one hundred of the leading charities in the United States, 66 percent of their 525 billion in net assets are subject to donor limits, meaning these charities have full control of only 34 percent of assets. For the nineteen private universities in this group, 67 percent of the total endowment is donor limited. This tax law subsidy for dead hand control entails many harms, including to the public interest, charitable autonomy, pluralism, the operational funding of charities, imposition of compliance costs, and subsidizing gains to donors. The Article considers tax reform options for donor-limited gifts. These include treating donor limits as retained rights or return benefits, estate tax reform to discourage giving to intermediaries, curtailing donor-limited gifts from donor-advised funds, and taking donor limits into account for purposes of any new giving incentive, such as a nonitemizer deduction or charitable giving credit. Importantly, under any tax reform approach, the power of donors to impose limits would not change. Donors could continue to limit their gifts in perpetuity as they currently do, but charity, and society, would be relieved from some of the costs of the dead hand
Congress Should Respond: A Payout for Some DAFs and New Rules for Noncash Contributions
Donor advised funds attract a significant share of charitable giving and warrant Congress’s attention. The national sponsoring organization is distinct from other DAF sponsors. The national sponsoring organization’s exempt purpose is to spend money for the benefit of other 501(c)(3) organizations, and is best characterized as a fundraising organization. Given the national sponsoring organization’s exempt purpose, it is already subject to a facts and circumstances based payout. Because national sponsoring organizations fundamentally are vehicles for spending not saving, Congress should apply legislatively the commensurate in scope test and require that national sponsoring organizations spend contributed funds over a specified time period. The goal is to provide a spending period long enough so as not to alienate new donors, but short enough so as not to extend unduly the delay to charity that results when DAFs are used as public charity substitutes. Congress also should note that DAFs increasingly are used for noncash charitable contributions. The positive effect will be to make property conversions more efficient. The negative effect will be to accentuate the broken system for property contributions at great expense. DAFs present an opportunity for Congress to reduce the cost of the subsidy for property contributions and move to a net benefit to charity approach to the deduction
