Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
Role of milk and dairy products in growth of the child
Cow's milk and dairy products intake increase linear growth in children and result in increased adult stature. This is supported by observational and intervention studies mainly from low- and middle-income countries. However, recent reviews primarily based on studies from well-nourished populations question the relation. The probable effects seem to be mediated by insulin-like growth factor-1 and insulin and to be more pronounced during periods of high growth velocity. Several components of cow's milk are suggested to stimulate growth: a high protein quality, bioavailable minerals that are important for growth, and perhaps lactose. Higher adult stature is associated with both positive and negative health effects. Growth stimulation is important in populations with undernutrition, but in well-nourished populations, it might not be important. A high intake of cow's milk and thereby a high protein intake early in life can increase the risk of later overweight and obesity, while a high protein intake later in childhood seems to be associated with a lower BMI later in childhood. A high dairy intake can limit the diversity of the diet and result in iron deficiency. Therefore, milk intake should not exceed 500 mL/day in young children. Most products for the treatment of undernutrition include dairy protein because of the well-documented effects on growth and recovery. However, as dairy is an expensive ingredient, the amount needed and the effects of alternative plant-based protein sources are considered.</p
Global Landscape of Nutrition Challenges in Infants and Children
Pediatric nutrition - Challenges and environmental impactsMalnutrition among children remains a persistent problem around the world. This publication aims to map the challenges within the global landscape of childhood nutrition and considers the importance of nutrition both prior to conception and in children beyond two years of age.Session I provides an updated picture of malnutrition around the world, the recent progress that has been made in eliminating malnutrition in all its forms and several data limitations to track such progress. The role of milk in early life is covered in session II. The chapters describe different aspects of cow’s milk and the possible role of optimized plant proteins as an alternative to dairy ingredients in treating children with severe acute malnutrition. Session III considers the ramifications of environmental constraints to healthy child growth. The chapters cover the issue of how persistent gut damage and systemic inflammation can precipitate malnutrition as well as the putative effects of alterations in the gut microbiota.This overview of diverse issues is relevant to the epidemiology, biology of nutrition in early life, programmatic implications, and future directions.<br/
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
