Multi-criteria decision-making in the management of humanitarian operations
No full textAlthough multi-criteria decision making topic is well suggested by some papers there are no researches that have been focused on its application into humanitarian operations with the presentation of a hierarchy process to support the operators in making choices. The purpose of this paper is to present a general multi-criteria decision making process to assist the evaluation of suitable alternative solutions to humanitarian operations management issues. Humanitarian operations are described in terms of a multi-objective field that reflects service level, timing and costing as final goals, and is composed of different life cycle phases, each with its particular features. Through a deep literature review, a framework is built and analysed to support decision makers in their evaluation of operations issues in which the objective hierarchy is defined. The structured procedure is developed and validated with some examples of possible applications. Thereafter, using a sensitivity analysis, a real case is discusse
Reverse logistics in humanitarian operations: challenges and opportunities
No full textPurpose – Whilst implementation of a broad range of reverse logistics (RL) practices is increasingly the norm within commercial supply chain management, they have had limited impact in the humanitarian logistics (HL) sector. The purpose of this paper is to analyse the challenges and opportunities for the application of RL in a HL context. Design/methodology/approach – Through a broad review of both the academic and practitioner literature, supplemented by informal discussions with senior humanitarian logisticians, the paper summarises the current state of RL within the HL sector before recommending ways in which practices that are increasingly found in a commercial context could be implemented. Findings – The findings indicate that, to date, the use of commercial RL practices is extremely limited within the HL sector, but there are a number of areas where their introduction be possible in the future. Research limitations/implications – Whilst the reviews of the literature were comprehensive, further and more detailed research into the RL practices (if any) undertaken by aid agencies needs to be undertaken in order that appropriate lessons and experiences can be implemented across the sector as a whole. Practical implications – Given the overall desire of humanitarian agencies to “do no harm” it will be increasingly important for such organisations to embrace RL practices in order to improve the sustainability of their disaster preparation and response activities. Social implications – In light of the generally increased awareness of the need to reduce the environmental footprint as well as improving the social and economic impacts of their supply chain activities, there is likely to be increasing pressure on aid agencies to adopt RL practices. This paper identifies some of the potential areas in which this can be undertaken, and the associated barriers to be overcome. Originality/value – To date, it would appear that no academic research has been undertaken into the RL practices within the HL sector. To this extent, the research represents a first look at a new sub-topic within the overall HL field
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
