Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Value Chain Mode of Cebolla Junca of the Aquitania, Boyacá
No full textEn un mercado globalizado y saturado de bienes y servicios, en el cual todos son commodities, la cadena de valor permite añadir factores diferenciadores a lo largo de su producción que da como resultado un valor agregado, el cual permite la preferencia en la decisión de compra y la competitividad en los mercados globalizados. Este trabajo corresponde a los resultados parciales de un proyecto de investigación. El presente artículo busca proponer un modelo para la cadena de valor de la cebolla Junca de Aquitania, identificando los actores que intervienen directa o indirectamente desde la siembra hasta su comercialización al por mayor. La metodología utilizada es mixta, la recolección de datos se realiza por medio de observación, entrevista, análisis documental, el instrumento a utilizar es un cuestionario diseñado por los autores. Se concluye que la cadena de valor es una de las herramientas más eficaces que existen puesto que, una vez comprendida facilita los procesos de innovación, mejora continua o toma de decisiones organizacionales.In a globalized and saturated market of goods and services, in which all are commodities, the value chain allows differentiating factors to be added throughout its production, which results in added value, which allows preference in the purchase decision and competitiveness in globalized markets. This work corresponds to the partial results of a research project. This article seeks to propose a model for the Junca Aquitaine onion value chain, identifying the actors that intervene directly or indirectly from planting to wholesale marketing. The methodology used is mixed, data collection is done through observation, interview, documentary analysis, the instrument to use is a questionnaire designed by the authors. It is concluded that the value chain is one of the most effective tools that exist since, once understood, it facilitates the processes of innovation, continuous improvement or organizational decision-making
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
Bioethical tensions and feelings in the decision making of adequacy of therapeutic effort by surrogate resulting in a do-not-resuscitate order for hospitalized patients
No full textEste es un estudio original en el que se desarrolló una investigación cualitativa de diseño etnográfico que explora las tensiones bioéticas y los sentimientos en los sustitutos que toman la decisión de adecuación del esfuerzo terapéutico que lleva a la directriz de no reanimación para pacientes hospitalizados, utilizando como herramientas de investigación grupos focales, entrevistas a profundidad, observación participante y revisión documental. Se analizaron los conflictos bioéticos y los sentimientos en un grupo de participantes (familiares, médicos y enfermeras) que han actuado como sustitutos en este tipo de decisiones, y los hallazgos se analizaron a la luz de la ética convergente de Ricardo Maliandi (con énfasis en el conflicto logos-pathos), la perspectiva psicológica de Antonio Damásio y la teoría psicoanalítica clásica de Freud. Los resultados demuestran la presencia de importantes conflictos bioéticos y emocionales en los sustitutos, así como el uso de mecanismos de defensa psicológicos individuales, al momento de afrontar este tipo de decisiones.Doctor en BioéticaDoctoradoThis is an original study in which a qualitative ethnographic design research was developed, which explores bioethical tensions and feelings in surrogates who make the decision to adequate the therapeutic effort that leads to the order of non-resuscitation for hospitalized patients, using as research tools focus groups, in-depth interviews, participant observation and documentary review. Bioethical conflicts and feelings were analyzed in a group of participants (family members, doctors, and nurses) who have acted as surrogates in this type of decision, and the findings were analyzed in the light of Ricardo Maliandi's convergent ethics (with emphasis on the logos-pathos conflict), Antonio Damásio's psychological perspective, and Freud's classical psychoanalytic theory. Results demonstrate the presence of important bioethical and emotional conflicts in surrogates, as well as the use of individual psychological defense mechanisms, when facing this type of decision

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
Contribution of Information and Communication Technology (ICT) in Country’S H-Index
No full textThe aim of this study is to examine the effect of Information and Communication Technology (ICT) development on country’s scientific ranking as measured by H-index. Moreover, this study applies ICT development sub-indices including ICT Use, ICT Access and ICT skill to find the distinct effect of these sub-indices on country’s H-index. To this purpose, required data for the panel of 14 Middle East countries over the period 1995 to 2009 is collected. Findings of the current study show that ICT development increases the H-index of the sample countries. The results also indicate that ICT Use and ICT Skill sub-indices positively contribute to higher H-index but the effect of ICT access on country’s H-index is not clear
Fully Turbulent Mean Velocity Profile for Purely Viscous non-Newtonian Fluids
No full textThe characteristic near wall behavior of turbulent flow of purely-viscous non-Newtonian fluids is discussed for both power-law (P.-L.) and Herschel-Bulkley (H.-B.) rheological models. A proper scaling is presented for H.-B. fluids to establish an analogy with power-law fluids with same flow index. To provide reference data for turbulent flow of non-Newtonian fluids, DNS simulations of power-law fluids are conducted in a rectangular channel for a large range of power-law indices ( = 0.5, 0.69, 0.75, 0.9, 1, 1.2). The DNS data show that the mean velocity profile in the viscous and logarithmic layers follow expressions of the form and respectively, where shows a logarithmic dependency on the flow index.Comparison with some experimental data shows the above formulation to be valid for Reynolds numbers (based on shear velocity) as high as 1000
