Equipment profile of South African Occupational Hygiene Approved Inspection Authorities
Full text linkMasters of Heath Science in Occupational Hygiene, North-West University, Potchefstroom CampusThe right to safe and harm-free working environments is provided for by the Bill of Rights, and reinforced by key legislative acts, such as the Mine Health and Safety Act 29 of 1996 and the Occupational Health and Safety Act 85 of 1993 (OHS Act). The OHS Act, in particular, mandates employers to maintain workplaces that are free from hazards, ultimately requiring the appointment of occupational hygiene professionals to uphold health and safety standards (SANS 2012:2). Specialised in hazard monitoring, Approved Inspection Authorities (AIAs) are sanctioned by the Chief Inspector to perform certified health and safety assessments. Their authorisation and approval are based on their strict adherence to the national standards set by the South African National Accreditation System. These standards outline the personnel, facilities, and equipment requirements. The extent of an AIA’s regulatory framework, or the different regulated hazards an AIA is allowed to assess, is based on the AIA's knowledge, expertise, and the appropriateness of their equipment. To guide AIAs, the Department of Employment and Labour (DoEL) published a list of equipment that highlights the types of equipment AIAs should use to assess the applicable hazards within their regulatory frameworks (SANS, 2012:5; SANAS, 2012:12). While the DoEL's equipment list outlines the basic equipment AIAs can retain for approval, staying up to date with rapidly advancing technology can be challenging for both new and more experienced AIAs. Equipment proliferation also affects the curricula of educational institutions, which aim to provide students with fit-for-purpose training. This raises an important question: What equipment is currently used by occupational hygiene AIAs, and why is it important? There are two main reasons why these questions matter. First, AIAs face a dual challenge. While trying to ensure competency, accuracy, and validity in their occupational hygiene operations, AIAs are also required to stay up to date with the latest technological advancements (SANS, 2023:12). Second, occupational hygiene students need to receive training that prepares them for real-world situations, and that is aligned with industry needs (Alanazi & Benlaria, 2023:5). The selection of equipment available on the market requires AIAs to choose the instruments based on their prioritised needs and the available information about this equipment. But, although manufacturers provide literature, the benefits, and capabilities of their equipment, the information AIAs need in order to make informed decisions are not as readily available (AIHA, 2017). Since the DoEL’s equipment recommendations were last updated in 20121, gathering the necessary information to make informed equipment decisions can be difficult. This can be particularly challenging for new AIAs trying to choose the right equipment. To address these challenges, a practical solution involved creating an equipment profile of national AIAs. This detailed profile aimed to identify the prevalent equipment and methodologies used by industry professionals. By identifying these prevalences, AIAs can have a reference point for comparison, and educational institutions can tailor their curricula to ensure fit-for-purpose training aligned with industry needs. This initiative aims to streamline the transition of occupational health and hygiene graduates into the workforce and provide clarity for companies, especially startups, seeking guidance on acquiring equipment that is both effective and in line with industry expectations. Employing a mixed methods research approach of sequential exploratory design, registered occupational hygienists — each representing one of the 53 registered Type A AIAs, and whereof only 11 responded to the questionnaire — were invited to an online survey. This survey was created and administered using the Google Forms platform and required AIAs to answer questions pertaining to the equipment and methods they currently employ for hazard monitoring. After doing a data analysis of the number of equipment, the most frequently selected equipment models, and brands, the popularity of instruments was calculated based on the number of times selected as well as the number of units currently used. The calibration frequencies, buying drivers, and hazard evaluation methods were also investigated. The quantitative data was then used to assist with the interpretation of qualitative data. These findings were reported as the representing equipment profile of participating AIAs. Findings showed the consistent preference participating AIAs had for user-friendly, reliable, and cost-effective monitoring equipment. Highlighting the importance of equipment practicality. Differences in the calibration practices, however, emphasises the need for clear guidelines on the external calibration frequency necessary for all equipment. While the most prevalent equipment and methods were established, these findings also reinforce how academic curricula can bridge the gap between the current and prospective industry-needs. 1 Within the brochure - Requirements for approval as an approved inspection authority: occupational health and hygiene (2012:12). Educational institutions can update their equipment inventories by incorporating both prevalent, and less popular equipment types while also enhancing students’ technical skills through the adoption of both old and new equipment models. This could prepare students for real-world challenges, encourage work-readiness, and ensure their curricula aligns with industry-needs. While this study had a few limitations, it still provides occupational health and hygiene professionals with a detailed equipment profile of AIAs currently in practice. However, the lack of participation may affect the representativeness of this profile since only 11 of the 53 recruited AIAs participated. The potential biases from self-reported data could also affect the accuracy of these results. Future studies are, therefore, encouraged to combine questionnaires with interviews or direct observations. This mixed-methods approach could help verify self-reported data and enhance its accuracy. While consulting with industry experts during the design process could ensure even more comprehensive data to be collected.Master
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
