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
The influence of organizational climate on sustainable relationships between organization and employees. The KION case study
No full textThis study considers factors influencing relationships on an employee and employer level (micro-level) as well as the effectiveness and performance of the organization as a whole (macro-level). The organizational climate plays hereby a central role as a determinant of the organizational behavior and success. However, few empirical studies consider the role of the organizational climate as a link between both the micro and macro levels and its influence on the creating sustainable business relationships leading to improved economic performance. To conduct the analysis, we derive a hypothesis building upon existing literature and test the hypothesis through survey of organizational members and by employing a structural equation model. The results show a very good relationship among all variables considered in the model, especially between innovation, trust, communication and sustainable relationships. The study provides also managers with a useful tool for evaluating the climate of the organization and the quality of relations with its members. Because only one organization was analyzed, the research results may lack generalizability. Future research would need to adopt the proposed model on other organizations and countries
Assessing the Impact of Sustainability Improvement Options on the Agri-food Supply Chain Governance Structures: Development of an Evaluation Tool
Full text linkThe competitiveness of a supply chain is driven by the ability of supply chain governance structures to adapt to the chains’ continuously changing technical and organizational characteristics. The present study addresses the adoption of sustainability improvement options in the area of organization and management in the agri-food sector; within this framework the study proposes a tool for assessing the impact of sustainability oriented processes on the supply chain governance structures, in turn influencing the competitiveness of the supply chain. Two different approaches, proposed by (Gereffi et al., 2005) and (Hobbs and Young, 2000) have been linked to provide a theoretical framework for the tool development. The proposed new conceptual framework links the dimensions defining five different governance structures complexity of transaction, ability to codify and capabilities in the supply-base (Gereffi et al.,) to the product characteristics, regulatory and technology aspects defined by Hobbs and Young as drivers influencing the vertical coordination of supply chains. The method suggested for measuring the relations between improvement options and the chain governance structure is the adopt ion of experts’ evaluations. This method improves the tool capacity to provide a context-related supply chain governance structure assessment and management
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
Collaboration and Sustainable Relationships: their Contribution to the Life Cycle Analysis in Agri-Food Supply Chains
No full textThe life cycle approach is widely used in the analysis of sustainability. Its application to supply chains is necessary since the product flows, from processing of raw materials to the final customer, are considered. The role of the organizational aspects, expressed in terms of relationships between the supply chain agents, is little considered in the life cycle analysis approach. The aim of this paper is to extend the scope of the food chain life cycle analysis by adding the organizational dimension to the environmental, economic and social ones. Within this context, Collaboration and Sustainable Relationships concepts have been explored based on a literature survey. A theoretical framework, describing their role in assessing the organizational dimension in the life cycle analysis of the food supply chains, is defined. A hypothesis on their joint influence on the supply chains performances is formulated
