    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

    Full text link
    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

    La presente investigación se realizó en la granja avícola “Quinde” de aproximadamente 92.000 aves (machos y hembras) de la raza Cobb, ubicada en la Parroquia: Nanegal, Provincia: Pichincha, con el objetivo de demostrar la sensibilidad de las aves a las diferentes longitudes de onda o color de luz. La investigación tuvo tres grupos de estudio: el grupo testigo (galpón con luz de color blanca), el grupo experimental 1 (galpón con luz de color verde), el grupo experimental 2 (galpón con luz de color azul); tomando como muestra para los pesos semanales un total de 1262 aves, en dos lotes, obteniendo mejores resultados el grupo testigo, el cual presentó un mejor promedio tanto de peso como de conversión durante los cuatro meses del estudio, cabe mencionar que en el grupo experimental 1, existió numéricamente una ligera diferencia con relación al grupo testigo al comparar los promedios obtenidos, con relación a la conversión alimenticia. Con respecto al grupo experimental 2, no tuvo los resultados esperados tanto en el peso como en la conversión alimenticia, demostrando así que las aves poseen más sensibilidad a la luz de color claro (blanco– verde) que a la luz de color obscuro o azul.This research was conducted in the poultry farm “Quinde” of about 92.000 domestic fowls (males and females) of the Cobb breed located in the Parish of Nanegal, Province of Pichincha. The objective was to prove the sensitivity of domestic fowls to different wavelengths or light color. The research had three different groups, they were: the witness group (white light shed), experimental group 1 (green light shed), and experimental group 2 (blue light shed), using as a sample for weekly weights a total of 1262 fowls, in two batches, and getting better results with the witness group, which showed a better average in weight as in conversion, during the four months of the study. It should be noted that in the experimental group 1, there was a slight numerical differences from the control group when comparing the averages obtained regarding feed conversion. With respect to the experimental group 2, there results were not expected results in both weight and feed conversion, showing that domestic fowls have more sensitivity to light-colored (white-green) than to dark light or blue

    The Role of Agricultural Economy Cooperative Societies in Combating Insecurity in Nigeria

    This paper examines the role of agricultural cooperative societies in combatting the menace of insecurity in Nigeria. The country is recently grappled with various forms of crimes and violence such as terrorism, armed banditry, and ethnic conflict among others. Therefore, the widespread of violence and insecurity in the country has negatively affected social and economic growth of the country. The insecurity has severely disrupted the livelihoods of Nigerians mainly the rural dwellers, it eroded trust among different Nigerian communities, and has exacerbated extreme poverty in the country. Against, this background, this study highlights the ways the cooperative societies in the country can contribute in enhancing community cohesion, promoting economic empowerment, providing social support. Among other things, this study also attempts to facilitate collaboration with security agencies. By the affective utilisation of the cooperative societies, the insecurity in Nigeria can be redress and eradicated to the minimal level. The societies can mobilize resources and foster resilience within the Nigerian people. The findings explicitly reveal that the potentials of the cooperative societies in addressing the insecurity have not been effectively utilised the need for a comprehensive approach to involve the cooperative societies in tackling the root causes of insecurity in Nigeria. However, the recommendations suggest for strengthening cooperative structures by the government through the involvement of the cooperative societies in promoting economic opportunities, and enhancing community engagement to create safer environments in the country

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    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
