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
Effective Test Administration in Schools: Principles and Good Practices for Test Administrators
No full textTo establish academic achievement in any public school, teachers have to construct, administer and score tests or examinations. For a valid and reliable assessment of academic achievement, the tests should yield similar and consistent results/grades for comparable groups of students. The validity and reliability of assessment are dependent on many factors among which are administrations of the measurement. This paper focuses on test administration principles and good practices in schools; highlighting principles and good test administration practices and concluding with a summary of the suggestions that, if followed, lead to successful test administration in a any given public school system. 
Prioritisation and Nationalisation of Teaching of Sciences in Ugandan Schools: Practitioners and Documentary Perspectives
Full text linkConsiderable investment in and prioritisation of teaching of sciences among secondary schools in Uganda have been made. But despite this, performance in sciences remains poor. We sought to understand why this is so, and to this end, the present study explores perceptions regarding reasons surrounding students’ poor performance in sciences. We used an exploratory case study to interview teachers of science, inspectors of schools, and a representative of the Uganda National Examinations Board. Also, documentary analysis was done for a deeper understanding of the study question. Qualitative analysis was employed in the identification of themes and sub-themes. In the findings, what our research suggested is that there is a combination of factors which have resulted in poor science results within schools – the quality of the teaching, the expectations and support of the school and the ability of the pupils themselves, although the quality of teaching seemed to be the major factor. Therefore, this would suggest that the teaching and learning of the sciences in Ugandan schools could benefit from adapting to new ways – teaching the necessary skills, developing the pupils’ scientific interest and skills, and improving facilities within the schools. Further inquiry could be channeled towards understanding apathy in the teaching and learning of sciences, support strategies in resource utilisation, and monitoring of the teaching-learning process
Socio-demographic correlates of psychoactive substance consumption among secondary school adolescents in a remote district of Buhweju, Uganda Adolescents in a Remote District of Buhweju, Uganda
No full textConsumption of psychoactive substances remains one of the hot-button debate of the 21st century. Many puzzles regarding consumption of psychoactive substances have been captioned in the correlates of the phenomenon. The purpose of the study was to establish the relationship between socio-demographic characteristics and psychoactive drug use. The data was collected using a Self-administered, semi-structured questionnaire. The data collected was processed and analysed using the Statistical Package for Social Scientists (SPSS V. 27). Logistic Regression was the main data analysis technique. The study was conducted among 08 randomly and purposively selected schools in Buhweju District. The study population was secondary school students. 350 students were recruited for the study. The response was by filling out the questionnaire. It was established that students affiliated with the Anglican religion exhibited higher odds of psychoactive drug use, as compared to their counterparts in the Roman Catholic Religion, (OR = 1.6; 95% CI = 1.00, 2.4, p = 0.049). The results were significant. No observation of peers consuming psychoactive substances also demonstrated elevated odds of engaging in psychoactive drug use (OR = 1.9; 95% CI = 1.19, 2.9, p = 0.006), indicating unique and varying risk factors among students. Students affiliated with the Anglican dominion had higher odds of consumption of the psychoactive substances, as compared to other dominions. Observation of peers who consumed the substances was on a significant risk for consumption of such substances.
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
Nexus between Family Socioeconomic Status and Alcohol Consumption Moderated by Religiosity among Secondary School Adolescents in Uganda
Full text linkThis paper focuses on the relationship between family socioeconomic status and alcohol consumption. It further covers the moderation effect of religiosity on the relationship between family socioeconomic status and alcohol consumption among secondary school adolescents in Bushenyi Ishaka Municipality in Uganda. The study employed a cross-sectional survey with quantitative method of data collection and analysis. The schools for the study were selected through a stratified proportionate sampling method. Schools were categorised into two strata; government and private secondary schools from which 6 of them were sampled and simple random sampling techniques were used to arrive at the final sample study of 404 participants from six schools. Data was collected using a self-administered questionnaire with standardised scales. The instrument comprised biodata, SES scale, religiosity, spiritual scale for Youth, and AUDIT Test for Alcohol use. Responses were obtained from a total of 404 participants who included females as the majority (54.7%). The mean age of the students was 15.91. Results show that there was a significant relationship between family socioeconomic status (SES) and alcohol consumption. Religiosity had significant positive moderation effect on the relationship between family socioeconomic status and alcohol consumption among secondary school adolescents. Religiosity is a strong resilience and deters adolescents from consuming alcohol regardless of their family socioeconomic status
