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
The Contingent Effects of Value Creation Processes on Project Value–An Empirical Analysis from Project Managers’ Perspective
Get PDFProjects are seen as platforms for bringing changes that may create value for stakeholders. There are two main schools of thought on the value creation processes; one based on transactional exchange theories and the other on relations-based theories. The former focus on value creation through reduction of transactional costs, while the latter emphasises addressing project stakeholder’s needs through establishing close interactions with involved parties. Accordingly, this research examines effects on project value of the two value creation processes for project delivery: independent value creation– where the firm relies on its capabilities and expertise to deliver the project, without the need for seeking collaboration from other firms; and value co-creation– where the firm and key stakeholders collaborate to deliver the project based on close relationships. Extant studies have conceptually identified the effects on project value of both value creation processes. Nevertheless, there is a little empirical investigation of these effects. Hence, the main objective of this research is to investigate how both processes of value creation affect project value and the moderating effects of two critical contingent variables –requirements uncertainty and project complexity– on the relationship between value creation processes and project value. The study employs a deductive approach to fulfil this aim, and applies a cross-sectional survey to collect data; 168 valid responses from Chilean project managers were returned. A multivariate analysis using PLS-SEM was conducted to validate the conceptual framework and to test the hypotheses. Contributing to literature, the findings demonstrate that both value creation processes impact jointly on project value, and these impacts are moderated by the current level of requirements uncertainty and project complexity. The theoretical and practical implications of the findings are discussed. Directions for future research are elaborated
Drivers of the value creation processes in projects: A systematic review of empirical studies
No full textEn las últimas dos décadas, la creación de valor ha sido destacado como un tópico relevante principalmente en áreas relacionadas con gestión estratégica y marketing. Diversos autores han afirmado su importancia argumentando que estrategia organizacional es el arte de crear valor y el propósito de cualquier organización es la creación de valor. El concepto de creación de valor ha sido reconocido incrementalmente como un elemento crítico a través del cual una organización, industria o nación puede lograr mayor competitividad y sustentabilidad. Entendiendo que los proyectos son plataformas para sustentar estos procesos de creación de valor en las organizaciones, este estudio conceptualiza, a través de una revisión sistemática de la literatura, los factores clave incluidos en los procesos de creación de valor en proyectos de manera de impactar positivamente el éxito del proyecto. Como resultado, las estrategias de gobernanza, los modos de interacción y los enfoques de gestión han sido definidos como los tres elementos críticos para generar valor en proyectos cuyas interrelaciones pueden propiciar un impacto significativo tanto para el desempeño como para la realización de beneficios. De esta manera, este estudio representa un primer paso para la conceptualización, desarrollo y validación de un modelo de los procesos de creación de valor
en proyectos cuyo efecto maximice el valor creado desde el proyecto tanto para el cliente, la propia organización que desarrolla el proyecto y las partes interesadas, en términos del costo, plazo y calidad/alcance y los beneficios de mediano y largo plazo que se esperan de él.In the last two decades, value creation has been highlighted as a relevant topic, mainly in areas related to strategic management and marketing. Several authors have affirmed the importance of value creation arguing
that organizational strategy is the art of creating value and the purpose of any organization is the creation of
value. The concept of value creation has been increasingly recognized as a critical element through which an
organization, industry or nation can achieve greater competitiveness and sustainability. Understanding that
projects are platforms to support these processes of value creation in organizations, this study conceptualizes,
by a systematic literature review, the drivers included in the value creation processes in projects to positively
impact on project success. As a result, governance strategies, modes of interaction and management foci have been defined as the three critical elements to generate value in projects whose interrelationships can cause a significant impact both for performance and for benefits realization. Hence, this study represents a first step for the conceptualization, development and validation of a model of value creation processes in projects whose effect maximizes the value created from the project for the client, the own organization that develops the project and the stakeholders, regarding the cost, time and quality / scope and the medium and long-term benefits expected from it
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
