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
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

Full text linkLearning outcomes of mathematics is a benchmark of high or low the quality of mathematics learning process. There are numerous factors which influence high or low learning outcomes of mathematics. However, the scope of study is on parents’ attention, self concept, and perception on mathematics and learning motivation. The study aims at discovering the influence of parents’ attention, self-concept, and perception on mathematics toward learning outcome of mathematics directly and indirectly through learning motivation. The study is an ex-post facto which casual in nature. The populations of the study were 447 grade VIII students of public junior high school at Ujung Loe subdistrict in Bulukumba district of academic years 2012/2013 with as many as 204 samples. Technique used in selecting the samples was equal size random sampling. The instrument used for the study were (1) scale of parents’attention, (2) scale of self concept, (3) scale of perception on mathematics, (4) scale of learning motivation and test of mathematics learning outcomes. Data were analyzed uing descriptive statistics analysis and SEM (Structural Equation Modelling) analysis. The results of the study indicate that (1) most of grade VIII students have parents’ attention, self concept, learning motivation which are in high categories, perception on mathematics is in good category. whereas, learning outcomes of mathematics is in fair category; (2) parents’ attention, self concept, and perception on mathematics gave positive and significant influence toward students’ learning motivation; (3) parents’ attention, self concept, perception on mathematics and learning motivation gave positive and significant influence toward learning outcomes of mathematics; (4) parents’ attention gave positive and significant influence directly through learning motivation toward learning outcomes of mathematics; (5) self-concept gave positive and significant influence directly through learning motivation toward learning outcomes of mathematics and (6) perception on mathematics gave positive and significant influence directly through learning motivation toward learning outcomes of mathematics

Pengaruh Keterlibatan Belajar Matematika terhadap Prestasi Belajar Matematika Siswa SMA Negeri 22 Kabupaten Gowa
Full text linkThis study aims to determine how much influence the Engagement of learning mathematics has on the mathematics learning achievement of students at SMA Negeri 22 Gowa Regency. The research method used is ex-post facto quantitative research which is causal. The population in this study were students of class XI SMA Negeri 22 Gowa with a total sample of 207 students. Data collection was carried out using instruments in the form of a learning engagement scale and report cards for the 2020/2021 academic year in mathematics. The data analysis technique used in this study is inferential statistics using simple regression analysis with prerequisite tests including normality tests, linearity tests. Based on the results of the study, it shows that there is a positive and significant influence between the Engagement of learning mathematics and learning achievement of students in SMA Negeri 22 Gowa Regency. This is proven by the value of t count = 4.113 with t table = 0.6757 and sig = 0.000 < = 0.05. It can be concluded that there is a positive and significant effect of Engagement learning mathematics on mathematics learning achievement. The magnitude of the influence of mathematics learning Engagement on mathematics learning achievement is 7.62%
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
