Lessons from 14 Countries
No full textThis sourcebook documents and analyzes a range of government-led school meals programs to provide decision-makers and practitioners worldwide with the knowledge, evidence and good practice they need to strengthen their national school feeding efforts. The sourcebook includes a compilation of concise and comprehensive country case-studies. It highlights the trade-offs associated with alternative school feeding models and analyzes the overarching themes, trends and challenges which run across them
Courage and Hope : Stories from Teachers Living with HIV in Sub-Saharan Africa
No full textIt is estimated that there are currently
approximately 122,000 teachers in Sub-Saharan Africa who are
living with HIV, the vast majority of whom have not sought
testing and do not know their HIV status. Stigma remains the
greatest challenge and the major barrier to accessing and
providing assistance to these teachers. The idea to collect
stories from teachers living with HIV was inspired during
the Association for the Development of Education in Africa
(ADEA) biennial meeting in Libreville, Gabon, in March 2006.
At the conclusion of the meeting, Margaret Wambete shared a
moving account of her life as a teacher living with HIV in
Kenya. Margaret's presentation alluded to the fact that
teachers living positively, in part due to their leadership
role and in part due to their visibility in society,
experience a unique set of challenges related to their
HIV-positive status. To emphasize the human dimension of
these stories, the technical team worked with journalists
rather than researchers. A seasoned journalist responsible
for the education section of a major Kenyan newspaper led
eight local journalists in documenting these stories.
Working with teacher unions and networks of HIV-positive
teachers in various countries, a number of HIV-positive
teachers were identified as willing participants for this
project. The journalists each interviewed teachers living
with HIV from their home country and recorded their stories.
Once collected, the stories were vetted for accuracy of
interpretation and then reviewed more widely at the meeting
of the African networks of ministry of education
HIV&AIDS focal points in Nairobi in November 2007. From
the interactions, the journalists learned that news
conferences, reports, or press statements they rely on for
information about HIV are not enough. Understanding the HIV
challenge requires close association with those living with
the HIV virus. These individuals have moving personal
testimonies that cannot be captured through hard facts and
figures. Only through close interaction can people living
with HIV express their fears, needs, and aspirations.
Personal testimonies from the teachers are a powerful tool
for spreading the message on HIV. Facts and figures are
important, but listening to those who have lived through the
experiences telling their stories makes the message more
potent. The lessons journalists learned from the exercise
will surely help them and readers of this book in redefining
their perception about HIV, especially in relation to
professionals such as teachers
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
