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
Chestnut as Source of Novel Ingredients for Celiac People
No full textChestnut is a nut cultivated in a variety of growing conditions and climates, being globally popular and valued for its sensory, nutritional
and healthy properties. European sweet chestnut (Castanea sativa Mill.) is mainly grown in the temperate regions of continental
Europe and has represented one of the most important and sustainable food resources of rural areas for many centuries.
Chestnut fruit is highly appreciated and extensively consumed throughout Europe, America and Asia, because is considered
a high nutritional value food, extremely versatile and safe. Recently, there is an increasing demand of both the fresh and transformed
fruit e.g. chestnut flour for its gluten-free characteristic and low fat content compared with other nuts for the development of glutenfree
for celiac disease patients, non-celiac gluten sensitivity people and consumers who avoid gluten for lifestyle reasons and of
health-related food products. The market for edible chestnuts has considerable potential for increase in production and demand
given growing consumer interest in alternative and healthy foods (Gold et al., 2004). Almost 20% of the total production is
used to make chestnut flour, dried chestnuts and the marrons glacé sweet
Sustainable Crops for Food Security: Quinoa (Chenopodium quinoa Willd.)
No full textThe pseudocereal quinoa (Chenopodium quinoa Willd.) is a crop that has endured the harsh climate conditions of the Andean region in South America since ancient times. Because of its stress-tolerant characteristics (the plant is cold, salt and drought tolerant) and of the high seed nutritional value and biological properties, quinoa has been described as one of the grains of the 21st century; and FAO launched the International Year of Quinoa in 2013. Quinoa seeds, and to some extent its leaves, are traditionally used for human and livestock consumption in the Andean region. Nowadays, quinoa cultivation has crossed continental boundaries to reach Europe. It is cultivated in France, England, Sweden, Spain, Denmark, Finland, Holland and Italy. It is grown in the United States and Canada, as well as in Kenya, in the Himalayas and India. Quinoa seeds are an exceptionally nutritious food source, owing to their high protein content rich in all essential amino acids, absence of gluten, high level of important minerals, such as calcium and iron, and health-promoting compounds such as flavonoids. Thus, quinoa provides a promising crop towards ensuring sustainable and safe food, e.g. gluten-free foods and nutritionally balanced products at affordable costs and a low impact on the environment
Forecasting, uncertainty, and public project appraisal
Full text linkUncertainty in project planning and appraisal is still topical in the World Bank and other lending and development agencies although it is certainly not a new issue. It is appropriate to reconsider the issue now because more than a decade of active research on risk analysis has transpired without, however, the seeming emergence of agreed procedures and practice. In particular, the implications for what information price forecasters should provide for risky project appraisers have yet to be clarified. In Section 2, theoretical arguments about the proper role of uncertainty in appraisal are reviewed, and this section is closed by discussion of the various'practical'methods that have been proposed, in and outside the World Bank. Further procedures for quantifying uncertainty in both forecasting and appraisal are considered in Section 3. Section 4 presents a set of procedures that seem workable and retain some theoretical defensibility. These are illustrated through an example. Finally, conclusions and implications are drawn out in Section 5.Economic Theory&Research,Environmental Economics&Policies,Health Economics&Finance,Statistical&Mathematical Sciences,Insurance&Risk Mitigation
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
