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
The determinants of employment status of young graduates from a South African University
Full text linkMCom (Economics)--North-West University, Vaal Triangle Campus, 2016.There has been a debate regarding the extent of graduate unemployment in South
Africa and how it has affected the youth. The main focus of this study was therefore
to identify the determinants of employment status among graduates, particularly the
length of unemployment endured by young graduates in South Africa. The focus on
graduates was necessary, given the understanding that once one has a university
degree, the opportunities to get a job are assumed to be high. It was also on the
premise of the substantial resources that are invested in higher education with the
hope of a higher return. The objectives of the study were categorised into theoretical
and empirical. The theoretical objectives were: to define unemployment and
graduate unemployment, review literature on various types of unemployment,
conduct a review on the problem of youth unemployment from a global, regional and
South African perspective, review the trend of graduate unemployment in South
Africa, and evaluate the factors that affect graduate unemployment.
The empirical objectives were: to determine the average time it takes a graduate to
find employment measured in months, assess if the employed graduates are
employed in their fields of study, determine if degree choice plays a significant role in
the employment prospects of graduates and to establish the personal and social
economic factors that determine the employment status of graduates in South Africa.
In achieving these objectives, a quantitative research method was adopted. The
study used 233 questionnaires collected via an online survey that was circulated to
the alumni database of the university in question. The study employed descriptive,
cross tabulation and a regression analysis to achieve the set empirical objectives.
The study had a well-balanced gender distribution with females making up 58% of
the sample and males 42%. The average time it took graduates in the sample to find
employment after graduation was seven months. Further analysis revealed that out
of the graduates that were employed, more than 70% were employed in their fields
of study with about 27% in jobs that they did not study for. Additional analysis to
determine the state of the graduate’s current job showed that many of them were in
jobs below their desired field, suggesting a problem of under-employment.
The results from the regression analysis indicated that age, race, field of study,
major module and job searching skills were significant predictors of unemployment
length. Religion, gender, and marital status were not significant in this regard. The
study indicated that 11.2% of the surveyed graduates were unemployed and the
majority were between the age of 21 and 24, implying that young graduates are
more likely to be unemployed than their older counterparts. Many of those who were
unemployed had qualifications in Humanities with majors in the arts subjects. The
average job waiting period was also found to be the highest for graduates with these
arts majors. An analysis was also done on the perceptions about graduate unemployment. The results showed that surveyed graduates perceived the lack of job market information, lack of job experience and not having political connections as some of the factors that influence graduate unemployment. In contrast, age, race, self-confidence and higher education institution attended were perceived as factors not having any influence on unemployment among graduates.
The study therefore concluded that the most important factors affecting graduate
unemployment are qualifications and majors held by graduates, which seem not to
be aligned with labour market requirements. This provides an opportunity for higher
education institutions to collaborate with the government and private sector to bridge
the gap that exists in academia and the world of work. Further analysis can be done
on a broader scale by increasing the sample size and doing the same study at
several universities in Gauteng.Master
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

Determinants of housing insecurity in a low income South African township
Full text linkThe campaign to end poverty by 2030, as advocated by the World Bank, has multifaceted components. Food security and abject poverty have received more attention; however, little attention has been focused on housing insecurity. This is important, especially given the fact that it is widely acknowledged that housing satiates an essential human need for physical security, dignity and prosperity, among other things. Housing, for some time, has been observed as crucial to individual and family functioning. As indicated by organisations such as the United Nations Habitat, the importance of appropriate housing is explained by the fact that safe housing is seen as a basic need among other needs such as food, all of which are regarded as central components of the security of ordinary households, particularly in developing countries. In 2015, more than 1.5 billion people in the world were living in housing that was unsafe and inadequate, while in the meantime, millions experienced eviction from their homes every year, with at least 100 million people becoming homeless on any given day. Therefore, it is pertinent to understand what determines housing insecurity. The study aims to investigate factors that determines housing insecurity. Using data collected from Sharpeville and Bophelong, two low income townships in South Africa that are particularly vulnerable to housing insecurity, the study employs a multinomial logistic regression to investigate the effects of head of household and the general household characteristics on housing insecurity. The results of the regression analysis show that income, gender, number of people in the household and the amount paid to bond or rent are significant predictors of housing insecurity. Contentious issues like access to land and job opportunities are areas of further study in understanding the multifaceted phenomenon of housing insecurity
