Risk in the aviation context : investigating risk perception and risk communication from a behaviour based approach
Get PDFSafety is an essential part of aviation. Risk assessment is considered subjective, while the
operational context necessitates conformity and a unilateral approach. Eventually, the results
assess individual risk perception and risk communication and are not being planned
proactively. Additionally, due to the diversity of organisations and cultures, there is further
fragmentation of what is recognised as risk behaviour, what should be communicated, and
what is hazardous. Considering risk perception and communication within the daily practice is
seen as essential to explain the behaviours during an adverse event. Safety analysis and
investigation methods (SAIMs) have the goal to suggest ways to achieve acceptable system
outcomes and avoid unfavourable consequences on humans, equipment, facilities, and the
environment. However, there is no widely common and accepted framework engulfing safety
recommendations and proactive safety management such as a behavioural intervention to
enhance risk perception and risk communication and minimise danger. Risk perception and
communication have been underrepresented in studies regarding their complexity in aviation
practice. They have not been explicitly addressed for their role in incidents/accidents,
resulting in ambiguous proactive safety suggestions and planning. Based on the premise that
risk behaviour results from inappropriate risk perception and risk communication, this thesis
supports that a behaviour-based intervention can enhance risk perception and
communication.
This thesis aimed to generate a holistic intervention plan to modify risk behaviour on the
assumption that risk perception and communication are the basic factors. The hypotheses
included that specific factors can be associated with risk perception and communication
leading to risk behaviour, which may be influenced to enhance the latter. Also, a complete
integrated intervention model can be generated and fused with a Strategic Communications
approach, which makes it usable by most aviation air-carrier organisations. The objectives are to determine two sets of risk perception and communication factors, which lead to risk
behaviour and then generate an integrated model applicable in the aviation context. This
thesis followed the pragmatism paradigm and adopted a fixed multiphase mixed methods
approach, investigating SAIMs, safety events reports, two groups of Subject-Matter-Experts,
and the wider aviation workforce. The resulting behaviour based model consolidates the role
of risk perception and communication factors as moderators of antecedent behaviour while
holistically envisaging the aviation work environment. Contribution to theory and practice
within the aviation safety context is provided, as well as future research for additional
applications of the mode
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
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
