    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

    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

    A critical analysis of the tax consequences of debt reductons, in the context of insolvency, death and the liquidaton of a deceased estate

    The present research was conducted in an effort to address certain problems and a legal anomaly that is specifically related to the tax treatment of reduced debts stemming from the death or insolvency of natural persons in South Africa. At the beginning of 2013 the National Treasury enacted certain amendments to the debt reduction provisions of the Income Tax Act 58 of 1962 with the intention of streamlining the tax treatment of reduced debts and granting debt relief to financially distressed debtors. In spite of these recent amendments to the provisions of the Income Tax Act, there are certain problems and a legal anomaly which still currently relate to the tax consequences of reduced debts in South Africa. These problems and the legal anomaly are based on the failure of the recent amendments to successfully address debt reduction which arises in the context of the death and/or insolvency of natural persons. The objective of this research was therefore to analyse the tax consequences of reduced debts arising in the context of the death and the insolvency of natural persons and to explain how the problems and legal anomaly associated with these tax consequences can be rectified. The research design was qualitative within the framework of an interpretive paradigm. A mixed methodology approach was followed as identified in the Arthurs Report (1983), namely the interdisciplinary and the doctrinal methodologies. This approach encompassed two legal research methods namely the expository and legal reform research methods. The research explained the underlying nature of the tax consequences of reduced debts arising in the context of the death and the insolvency of natural persons and formulated specific reform measures aimed at remedying the problems and the legal anomaly that currently exist. Two amendments were proposed. It was proposed that the tax liability which arises when debts are reduced through the wills of deceased persons and the reduction of debts stemming from the insolvency of natural persons should be expressly excluded from falling within the ambit of the provisions which give rise to tax consequences whenever debt reduction takes place

    Trustworthy Machine Information Behaviour and Open Research Repositories

    No full text
    The perception regarding the nature of repository users is changing as a result technological advancements. This is reflected in arguments contending that machines should be recognised as users of library services. Such arguments are based on the view that library collections such as open repositories should be considered as data that can be used by artificially intelligent machine users. These arguments raise questions regarding the concept of trust as they do not actually address attributes that machines users must possess in order for them to be considered trustworthy. This research develops a conceptual framework for understanding the parameters within which trustworthy machine information behavior can emerge. This outcome is achieved by applying machine ethics to a modified version of Wilson's general theory of information behavior that incorporates elements of machine learning. The results indicate that the level of trust placed in machines users is dependent on the algorithms and software used for programming such AI systems as well as the actions of humans who make use of such machine users. In order for any semblance of trust in machine users of open repositories to exist, the machine information behavior employed by the machine users should adhere to certain ethical principles
