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
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
Cross-sectoral hybridization as a strategy to turn institutional voids into opportunity spaces
Get PDFOrganizations that aim at delivering essential goods and services to low-income populations a the base of the pyramid increasingly blend the social welfare and the commercial logics in an effort to create financially sustainable solutions to social problems. Scholars have portrayed these cross-sectoral hybrid organizations as particularly agentic and resilient in institutionally complex settings, highlighting their ability to turn institutional voids into opportunity spaces. At the same time, the reconciliation of two antagonistic goals, namely poverty alleviation and financial value creation, as well as the multiple institutional voids that hybrid organizations face at the base of the pyramid (BoP) expose them to severe tensions. By investigating eight hybrid organizations in four countries, namely Colombia, Mexico, Kenya and South Africa, the present study contributes to a better understanding of cross-sectoral hybrid organizations in BoP settings in two ways. First, it shows that hybrid organizations not only face tensions between sector logics, but also between formal and informal, as well as between “Western-style” and “local style” strategic action fields. In settings which do not effectively provide guidance on the prioritization of social vs. financial objectives, these institutional voids manifest as tensions over goals and tensions over means in hybrid organizations.Second, the study sheds light on how field-level dynamics influence the ability of hybrid organizations to strategically employ factors that spur legitimacy advantages in an effort to turn institutional voids into opportunity spaces. Two different scenarios have been identified. One scenario refers to Colombia, Mexico and Kenya, which have been classified as fields that don’t effectively enforce a dominant sector logic concerning the legitimate way that health services should be provided to low-income populations. The present study has shown that in such fields, an organization’s logic of origin as well as the personal background of founders are factors that may spur legitimacy advantages in hybrid organizations. In effect, organizations which strategically employ these factors can select more freely from competing logics and ultimately overcome the prevailing tensions. This resonates with previous research, which has suggested that in fields with a dominant logic, hybrid organizations may take advantage of legitimacy advantages if their logic of origin corresponds to the dominant logic at the field level (Pache and Santos, 2012). However, the present study suggests that the factors leading to legitimacy advantages are more complex in fields with no effective dominant logic regarding social service provision. Here, the dominant logics among funding organizations, possible legitimacy spill-over effects from other market players, as well as the specifications of the commercial and the social welfare logics become important sources of possible legitimacy advantages. However, the study suggests that an organization’s ability to employ them strategically is dependent on their time of founding and their size.In addition to these findings, the study also provides insights on cross-sectoral hybridization in fields with a weakly enforced dominant logic, which is the second scenario that has been identified in South Africa. In particular, the study suggests that in such settings, hybrid organizations are more restricted to freely draw from competing logics, given that they face effective, normative imperatives about the goals they should pursue. However, the empirical investigation also indicates that an organization’s resource dependence structure is more influential than the encountered normative claims of audiences in health fields at the BoP. Further research is needed to refine these insights and explore cross-sectoral hybridization in social service provision fields in contexts of a weakly enforced dominant logic. Based on these findings, the author derives a range of practical recommendations that may themselves be interpreted as paradoxical. As the empirical study suggests, blended value creating hybrid organizations in Colombia, Mexico and Kenya currently face legitimacy advantages when originating from a commercial origin. The researcher is thus, on the one hand, inclined to recommend them to position themselves as commercially oriented organizations as to take advantage of the legitimacy advantages that the commercial logic currently entails. On the other hand, she cautions actors in the field of blended value creation, particularly funding entities, not to neglect the actual role of nonprofit organizations. The establishment of (health) markets that provide low-income populations in developing and emerging economies with affordable, high-quality products and services is likely to require significant unprofitable efforts. Finally, hybrid organizations in South Africa need to be more careful when adopting structures or practices from the commercial logic given the low legitimacy that this logic has in the health market at the BoP. There, organizations need to thoroughly analyze the institutional claims in the specific context of post-Apartheid South Africa
