No full text3D anthropometric data collection for occupational ergonomics purposes: a review
Get PDFThis paper presents a literature review of anthropometric data collection to address occupational ergonomics issues. One of the uses of anthropometry is to assess the negative effects associated with working postures. Using new techniques, such as 3D body scanners, it is possible to have very reliable data to use in the en-hancement of workstation design or other ergonomic interventions, in order to prevent work-related musculo-skeletal disorders
A systematic approach for externalities in occupational safety through the use of the delphi methodology
No full textRamos, D., Arezes, P. M., & Afonso, P. (2015). A systematic approach for externalities in occupational safety through the use of the delphi methodology. Paper presented at the Occupational Safety and Hygiene III - Selected Extended and Revised Contributions from the International Symposium on Safety and Hygiene.Organizations should conduct an assessment of their occupational hazards with the regularity required by law and in order to design and implement preventive measures that are deemed necessary and sufficient to maintain the level of risk and the costs of prevention and the safety at the level considered acceptable by the organization. The design of preventive measures and the selection of measures to be implemented in an organization depend on various aspects and should take into account internal and external costs. In the present paper, an application of the Delphi method to the issue of externalities has been made. After three rounds it was possible to obtain significant findings and a better understanding of the problem of externalities in Occupational Health and Safety (OHS).(undefined

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
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
An overview of the current three-dimensional body scanners for anthropometric data collection
Get PDFThree-dimensional body scanners have revolutionized the anthropometric data collection. These data can be used for numerous applications, in different fields of expertise. However, there are different types of technologies and products to be used, influencing the results obtained. This paper presents a non-exhaustive synopsis of the existing technologies and products available in the market.(undefined
Wheelchair users’ anthropometric data: analysis of existent available information
Get PDFAnthropometric data represents the characteristics of a given population and, as such, it varies accordingly. Wheelchair users have, most times, different body characteristics than able-bodied people. These differences can be noticed also in terms of anthropometric data. This paper demonstrates the differences between the results ob-tained in several studies where anthropometric data of wheelchair users was collected. The results of the com-parisons between studies demonstrated that there are some dissimilarities on the data collected. The several stud-ies use different data collection protocols, which compromises the results and the comparability of the results obtained. Hence, it become unclear if the data collected in these studies is accurate and valid enough to be used in other future studies
