The analytical hierarchy process in the suppliers selection problem: an analysis at fly of seagull
No full textThe Supplier Selection Problem (SSP) consists of analyzing and measuring the performance of a set of suppliers in order to rank and select them with the general objective of improving the competitiveness of the entire supply system. Since many factors should be taken into account, very often conflicting each other, the problem can be tackled using multi-criteria approach. A survey of the scientific literature highlights that the most used methodology is the Analytical Hierarchy Process (AHP) with its variants.
In this paper a careful scrutiny of the papers appeared on international scientific journals in the recent years on the SSP is provided. In particular the analysis focuses on the use of AHP and its variants to solve different aspects of the problem. The results of the study allow individuating opportunities and open issues arising by the use of multi-criteria approaches, with particular reference to AHP-based models, to model the SSP
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
Assessing the effect of narrative transportation, portrayed action, and photographic style on the likelihood to comment on posted selfies
No full textPurpose - This paper aims to assess the effect of narrative transportation, portrayed action and photographic style on viewers' likelihood to comment on posted consumer photos.Design/methodology/approach - Integrating visual semiotics and experiments, this research examines the influence of consumer photos on viewers' likelihood to comment on the visualised narrative. One pilot, three experimental and a content analysis involve photos varying in their narrative perspective (selfie vs elsie) and portrayed content (no product, no action or directed action). The authors also test for the boundary condition of the role of the photographic style (snapshot, professional and "parody" selfie) on the likelihood to comment on consumer photos.Findings - Viewers are more likely to comment on photos displaying action. When these photos are selfies, the effect is exacerbated. The experience of narrative transportation - a feeling of entering a world evoked by the narrative - underlies this effect. However, if a snapshot style is used (primed or manipulated) - namely, the photographic style appears genuine, unconstructed and natural - the superior effect of selfies disappears because of greater perceived silliness of the visualised narrative.Practical implications - Managers should try to motivate consumers to take selfies portraying action if their aim is to encourage electronic word-of-mouth.Social implications - Organisations can effectively use consumer photos portraying consumption for educational purpose (e.g. eating healthfully and reducing alcohol use).Originality/value - This research links consumer photos and electronic word-of-mouth and extends the marketing literature on visual narratives, which is mainly focused on company rather than user-generated content
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
