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
Exploring Talent Management through Competency-based Profiling Model for More Effective Training and Development Planning – Case Herman IT
Full text linkHuman resource management is a pivotal part in driving a company to success. This stands true for all companies in every industry, including the currently booming technology industry. Herman IT - a Kajaani-based technology company - is planning to establish its own human resource management (HRM) department and needs of a competency-based talent management model as a guideline for its HRM. The purpose of this research is to explore Herman IT’s current talent management and compare it to a competency-based talent management model, thus drawing out suggestions for Herman IT’s problems based on the comparison.
The theoretical background of this research includes the definitions of human resource management, talent management and competency. This research also uses Google as a benchmark case study to build up the competency-based talent management model.
The quantitative research method was utilized in this research. The analysis of the findings collected from close-ended survey provides information about Herman IT’s current talent management situation, as well as its current problems with talent management. The analysis also represents the opinion of a part of Herman IT’s employees on how they want the talent management to be, thus giving some ideas for solving Herman IT’s talent management problems
Looking into the black box: The roles of development workers in enhancing climate resilience and gender equality for ethnic minority women through the EmPower project in Vietnam
Full text linkThe climate change-gender nexus has increasingly become the arena in which adaptation interventions take place. One such intervention is the EmPower program in the Asia-Pacific region by UN Women and UNEP. This research is a case study on how one program component on women’s renewable energy entrepreneurship is implemented in Vietnam. Through the perspectives of development workers at CHIASE – EmPower’s partner in northern Vietnam – the research examines what decisions were made about the project implementation, what or who influenced those decisions, and how the project strives to strengthen gender equality within ethnic minority communities. Semi-structured interviews with development workers constitute the main method for data collection, supported by an analysis of program and project documents. Thereafter, empirical data is analyzed using thematic analysis. The feminist political ecology of climate change by Noémi Gonda provides the theoretical foundation for the research. The theory prioritizes attention to the individual scale of analysis, power relations, and intersectional perspectives in the processes of knowledge-making and adaptation to climate change. In essence, this research aims at making visible the personal perceptions, understandings, and experiences of local development workers as well as the context in which they work. These individuals are not simply implementers of a development program but active agents playing different roles, navigating unique conditions and challenges, and ultimately influencing how the EmPower program can improve gender equality in Vietnam
Core-shell structures based on dendritic polymers sensitive to external stimuli: applications to the synthesis of gold nanohybrid materials
No full textLe travail présenté dans ce manuscrit décrit la conception et la synthèse d'architectures cœur-couronnes à base de polymères dendritiques, ainsi que les différents états d'assemblage de ces polymères (phases lyotropes, hydrogels, cristaux liquides) et enfin l'incorporation de nanoparticules d'or dans ces systèmes. Différents types de cœurs ont été utilisés dans ce projet: des polymères hyper-ramifiés polyamidoamine, des dendrimères de polyamidoamine et des dendrigrafts de polylysine. Ces cœurs ont été fonctionnalisés soit avec un polymère thermosensible de type poly(N-isopropylacrylamide) via un couplage amide, soit avec un tensio-actif comme le dodécyl sulfate de sodium ou avec des copolymères présentant des séquences ioniques, ces deux derniers cas via des interactions ioniques. Les polymères cœur-couronne s'organisent en phases organisées lyotropes ou thermotropes en fonction de leurs architectures et de leur environnement. Les différentes phases formées par ces structures ont été utilisées pour stabiliser des nanoparticules d'or préformées ou pour les synthétiser in situ. L'influence de la présence de nanoparticules sur l'organisation du polymère et sur les propriétés des systèmes hybrides (mécaniques, stabilisation ...) a été étudiée. En outre, l'influence de ces systèmes sur la croissance de nanoparticules formées in situ a été évaluée. La taille des nanoparticules d'or est dictée par la nature de la phase organisée qui est elle-même liée à la structure du polymère hyper-ramifié.The work presented in this manuscript describes the design and synthesis of core-shell architectures based on dendritic polymers, as well as the different assemblage states of those polymers (lyotropic phases, hydrogels, liquid crystals) and finally the incorporation of gold nanoparticles inside such systems. Different types of cores were used in this project: polyamidoamine hyperbranched polymers, polyamidoamine dendrimers and polylysine dendrigrafts. These cores were functionalized either with thermoresponsive poly(N-isopropylacrylamide) via an amide coupling, or with sodium dodecyl sulfate surfactant by ionic interactions, or with ionic block copolymers also by ionic interactions. The core-shell polymers organized into aggregates in aqueous solution, gels or liquid crystals depending on their architectures and their environment. All the phases formed by these structures were used to in situ synthesize gold nanoparticles as well as to stabilize preformed gold nanoparticles . The changes in these phases induced by the incorporation of nanoparticles as well as the properties of the hybrid systems (mechanical, liquid crystal character, stability ...) were presented. Furthermore, the " soft-template " effect of these systems on the size of the in situ formed nanoparticles was studied. The size of gold nanoparticles was governed by the nature of the assembled phase related to the structure of the hyperbranched polymer
