Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
The dialogical relationship between adolescents and parents : prevention of risk behaviour
Get PDFThesis (M.A. (Psychology))--North-West University, Potchefstroom Campus, 2012.Risk behaviour amongst adolescents represents a major public health challenge in South Africa particularly when considering the statistics on sexually active youth, adolescent pregnancies, smoking, drinking and drug abuse amongst the youth. Although various reasons can be given to
explain this phenomenon, the parent–adolescent relationship has proven to be a huge factor in the prevention of risk behaviour. However, even though the importance of such a relationship has
been proven, risk behaviour amongst adolescents still persists. This study specifically looks at the dialogical parent–adolescent relationship and how adolescents who engage in risk behaviour are affected by the relationship and how it can prevent risk behaviour. The content of section A explains the orientation towards the research, the problem rationale and the goals and objectives of the study. The researcher followed a qualitative approach as she tried to obtain an understanding of adolescent risk behaviour and how the nature of the dialogical parent–adolescent relationship could prevent such risk behaviour. Semi–structured interviews were conducted with
five girls and three boys who lived in Pretoria, as well as with their parents. The adolescents were between the ages of 14 and 17 and all engaged in risk behaviour. In section B a literature study is given with a brief outline of the methodology that was used. Specific focus falls on the findings of
the study. Section C contains the summary, evaluation and conclusions of the overall study. This research was done in order to make recommendations to parents of adolescents who engage in risk behaviour as a possible way to prevent it. This study highlighted how unprepared and uninformed parents were in terms of their parental skills and the needs of their adolescent children. The study also highlighted the need of the adolescents to be validated, and the lack of understanding and warmth in the manner that their parents relate to them. Adolescents still need parental guidance and a sense of belonging. The very poor relationships that exist between parents and adolescents strengthened the researcher’s hypothesis that the adolescents get involved in a range of dubious activities and their parents’ ineffectiveness to intervene and assist their adolescents through these challenging times, may lead to risk behaviour.Master
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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

Identifying opportunities for leveraging industry 4.0 technology in petrochemical engineering, procurement, and construction projects in South Africa
Get PDFMBA, North-West University, Potchefstroom CampusEngineering, procurement and construction projects (EPC) are notorious for cost and schedule
overruns. With the declining profit pool of the petrochemical industry in South Africa, EPC
contractors need to answer the call to reduce the capital expenditure of petrochemical plants by
increasing the efficiency of capital project execution.
The manufacturing sector enjoyed high productivity gains with the introduction of Industry 4.0 in
the German public-private sector. On the contrary, the construction sector saw marginal increases
in productivity, which is partly the effect of the delayed adoption of technology. This study aimed
to identify opportunities to leverage Industry 4.0 technology against the challenges faced by the
petrochemical EPC sector in South Africa.
The study's primary objective was to derive a theoretical framework for leveraging Industry 4.0
technology to address challenges in the South African petrochemical EPC sector that result in
cost and schedule overruns in EPC projects. To derive the framework, the study consulted the
literature available to identify recurring challenge themes faced in engineering and construction
projects. As a secondary objective, causation research was conducted to determine the factors
that influenced the recurring themes. The literature was further reviewed to uncover the potential
applications of Industry 4.0 technology in EPC projects.
To validate the challenge themes and to identify additional challenges true to the geographic
demarcation, the researcher conducted semi-structured interviews with experienced project
professionals within the petrochemical EPC sector in South Africa. The challenge themes were
validated, and as secondary objectives, the current state of digitalisation and the perceived
barriers to technological innovation within the petrochemical EPC sector in South Africa were
determined.
The study finds that the challenges faced by the petrochemical EPC sector in South Africa are
fundamentally the result of poor communication through the various and complex interfaces in
the project functions. A framework is presented wherein increased collaboration between project
stakeholders is promoted, and communication is enhanced by leveraging Industry 4.0
technologies. Building Information Modeling (BIM) is deemed the technology that would form the
foundation of the technological shift of the petrochemical EPC sector in South Africa. It is
proposed that BIM strategies be developed in close collaboration with the owners of
petrochemical plants in South Africa to achieve standardisation in implementing BIM throughout
the South African EPC sector.
Addressing the challenges faced in the South African EPC sector will not be possible with
technology as the only change source. The author notes that even though the findings show
enormous potential within Industry 4.0 technology, a parallel cultural shift is required among
project stakeholders to create an EPC environment characterised by trust and transparency.
Therefore, an integrated approach to project delivery is implemented as part of the framework,
which promotes contractual agreements that reward project stakeholders for achieving their
shared objectives, is characterised by shared risk rather than shifted risk, and promotes
collaboration between project parties.
Charles Darwin famously said: "It is neither the strongest, nor the most intelligent of a species
that survives, but the one that is most adaptable to changes". The South African petrochemical
EPC industry is changing, and EPC contractors need to answer the call to reduce the capital
expenditure of petrochemical plants.Master
