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
Diet containing dairy foods positively affects weight and fat loss and cytokines blood levels in premenopausal obese women.
No full textBACKGROUND: Several researches studied the relationship between Ca assumption and overweight/obesity. Levels of Ca supplementation higher than requirement, were related to increased fat loss in subjects at ipo-caloric diet and Ca from dairy foods resulted more effective than Ca from mineral source in the promotion of weight loss.
OBJECTIVE: Since the available studies were conducted using very high levels of Ca supplementation or on subjects fed Ca lacking diet, we studied the role of Ca from dairy foods on subjects receiving ipo-caloric diet, with Ca content adequate to the requirements.
METHODOLOGY: 40 pre-menopausal, women nursed for their obesity and eating or not dairy foods, were recruited for the study. They received ipo-caloric diets, with Ca equal to requirements. Subjects avoiding dairy products received also a Ca supplement (No Dairy group, n = 15), while other women eating at least 2 servings/d of low fat dairy products (Dairy group, n = 40). Body weight, abdominal fat and blood parameters were monitored at the beginning and at the end (3 months) of the experiment. Age and BMI were: 37.7 + 7.5 years and 34.4 + 3.7 for subjects included in the Dairy group and 39.8 + 9.8 years and 33.8 + 3.5 for women of No Dairy group.
RESULTS: Women in the Dairy group showed a weight loss of 7.03% respect the initial weight, while in women avoiding dairy products the weight loss was 3.21% (P<0.01). The whole body fat loss was 10.79% and 6,0%, for Dairy and No Dairy respectively, however the consumption of Ca from dairy foods did not affect waist circumference and abdominal-visceral fat.
No evidence of significant effect of the food treatments on the main haematological parameters related to the adipose tissue metabolism were seen. Insulin levels did not showed significant variations. Leptin concentration in blood decreased between the beginning and the conclusion of the trial as a consequence of fat mass decrease (P < 0.10), but without difference between the dietary treatments. Instead the IL-6 showed a higher reduction in subjects receiving the Dairy+ diet compared to diet without dairy products. The IL-6 levels showed a significant decrease between the beginning and the end of the experiment, apart from the diet (1.20 vs 0.66 pg/ml; P 0.0135).
Both the adiponectin and the unesterified fatty-acid concentration were not influenced by the diet but, while adiponectin decreased between the beginning and the end of the study, NEFA did not show significant variations along time.
IL-6 was positively correlated with leptin and fat mass, confirming the relationship between fat accumulation and inflammatory status.
CONCLUSIONS: Diets containing dairy foods have increased body weight and fat loss compared to diet lacking of milk and derivatives. Also the blood levels of IL-6 resulted lower in Dairy diets
Nutritional research activity in food dudes project: preliminary results
No full textFruit & Vegetables provide a significant part of human nutrition, as they are important
sources of nutritive and non-nutritive food constituents. There are convincing evidences that
increasing the consumption of vegetables and fruit by the general public can reduce the risk of
several chronic diseases, including stroke, cardiovascular diseases, type 2 diabetes, and cancer.
In the last Italian National Food Consumption Survey, the overall individual consumption
of F&V was 208 g/d and 210 g/d respectively. This amount meets the minimum population
goal for F&V consumption but it is inadequate to prevent chronic diseases. Despite the
numerous nutritional educational program, children and adolescents have a high intake of
unhealthy snacks and a low intake of F&V, too. Recently, the peer modelling and rewardsbased
intervention was shown to be effective in bringing about substantial increases in children’s
consumption of fruit and vegetables in Anglo-Saxon countries. Since September 2011
in three public urban primary schools in Milan, Italy, we started the Food & Fan Projects
aimed to increase the F&V consumption in children six to ten years old. Five hundred ninetyfive
children six to ten years old were enrolled in this study. Of them 413 were exposed
to the program whereas 182 simply were offered fruit and vegetables at the morning snack.
The project is ongoing but the preliminary results offer unique data on the nutritional status
with particular reference to indicators of visceral and subcutaneous fat distribution in this
class of age
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

No full textAppropriate 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
