Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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

Розробка моделі комплексного оцінювання рівня ризику банкрутства підприємства
No full textThe object of this study is the process of assessing the risk level of enterprise bankruptcy based on a comprehensive analysis of both quantitative and qualitative characteristics of its business processes. The problem addressed in this work concerns the improvement of bankruptcy risk prediction models. Existing approaches suffer from several significant drawbacks. In particular, the BR model lacks sufficient flexibility. It requires strict preliminary ranking of influencing factors and relies on formalized weighting systems. This limits the individualization of the analysis and reduces the accuracy of the assessment.
The essence of the obtained results lies in the development of a model of comprehensive assessment of enterprise bankruptcy risk level (MCAEBRL). This model implements a comprehensive analysis of the enterprise's business processes using both quantitative and qualitative characteristics. Ranking of factors is not mandatory. Instead, the model uses actual normalized weights determined by experts. It supports flexible rating scales for various indicator types, enables fuzzification of data to handle linguistic evaluations of indicators, and allows a group of experts to be involved to enhance the objectivity of the results.
The importance of the obtained results is explained by the features of the MCAEBRL construction. A process-based and integrated approach was used to analyze the enterprise’s activities. A multi-level hierarchy of business processes was employed, as well as quantitative and qualitative indicators for their characterization. Assessments were conducted using broad rating scales. The model uses fuzzy set theory to handle both precise and imprecise data.
The proposed model can be practically applied to assess the financial stability of enterprises across various industries. It is especially useful in unstable economic environments. The model is suitable for working with data of different nature and accuracy levels. It can also be used in cases where expert knowledge needs to be taken into account, thus improving the objectivity of bankruptcy risk assessment.Об’єктом даного дослідження є процес оцінювання рівня ризику банкрутства підприємства на основі комплексного аналізу кількісних і якісних характеристик його бізнес-процесів. Проблема, що вирішувалася у роботі, стосується удосконалення моделей прогнозування ризику банкрутства. Існуючі підходи мають низку суттєвих недоліків. Зокрема, BR-модель недостатньо гнучка. Вона потребує попереднього жорсткого ранжування факторів впливу. Також модель використовує формалізовані системи ваг. Це обмежує індивідуалізацію аналізу та знижує точність оцінювання.
Сутність отриманих результатів полягає у розробці моделі комплексного оцінювання рівня ризику банкрутства підприємства (MCAEBRL). У цій моделі реалізовано комплексний аналіз кількісних і якісних характеристик бізнес-процесів підприємства. Упорядкування факторів не є обов’язковим. Натомість використовуються реальні нормовані ваги, визначені експертами. Модель підтримує гнучкі шкали оцінювання для різних типів показників, забезпечує фазифікацію даних для роботи з лінгвістичними оцінками значень показників та дозволяє залучати групу експертів для об’єктивізації результатів.
Важливість отриманих результатів пояснюється особливостями побудови MCAEBRL. Для аналізу діяльності підприємства було застосовано процесний та комплексний підходи. Було використано багаторівневу ієрархію бізнес-процесів, а також кількісні й якісні показники для їх характеристики. Оцінювання проводилося за допомогою широких шкал. Для обробки точних і нечітких даних застосовувався апарат нечітких множин.
Запропоновану модель можна використовувати на практиці для оцінювання фінансової стійкості підприємств різних галузей. Вона особливо корисна у нестабільному економічному середовищі. Модель підходить для роботи з даними різної природи та точності. Її також можна застосовувати, коли потрібно врахувати експертні знання. Це підвищує об’єктивність оцінювання ризиків банкрутства

Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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
No full textWe 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
