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
Medmaster. Post-graduate training on multimedia education
No full textFrom the national searches on the cultural consumptions of the young Italians emerges with obviousness that
the young people are more genetic and naturally arranged to build a faithful relationship with the media, almost in an
instinctive manner, mentally elective and logically similar. This gift "digital" almost innate derives certainly from the
trial of immersion of the same young in the technological and linguistics convergence time, almost pits a generational
feature, and unavoidably produces some social and cultural and anthropological results, difficult solvable (Buckingham,
2008).
The crisis of the school, much discussed in public and scientific debate, is certainly the result of a series of
transformations in the proceeded of socializing, in which the relation between parents and sons, between teachers and
students is deeply changed, thrown off balance on the seconds. It is like if, in the course of the time, the recognition of
the centrality of the subject in the pedagogical teaching models had lost its educational valence transforming itself in the
legitimization of a taken of power of the young, or of an unaware legacy aside of the same teacher. The results of this
extreme imbalance of role bred an educational failure, a deficit of socializing, overturning the subordination of the roles
between educator and student. This one predominates the first one in the sense that it takes away from the educational
trial proposed from the teacher, as a delegitimation from its role, because bearer of values not more socially and
culturally recognized or at least shared. The sociological and anthropological reasons of these changes are able to be
complex and difficult to be circumscribed in an explanatory and synthetic model.
Nevertheless the intervention of the media in the cultural, social, communicative and interactive proceeded of the young has certainly contributed to intensify, or simply to give back visible, this dimension of the crisis. So, it is very important to analyse the real nomadic attitude of the young facing the different medial stimuli, the level of different utilization, support with the conviction that all the media can to be introduced at the same level in the hierarchical staircase of social, cultural or subjective importance for the youth, or better than not any medium can be considered more important respect to the other in the daily life of an individual.
The consciousness of the relation between young and the different medial languages, in limits of utilization, is certainly functional to understand the level of integration of the media in the cultural habits of the boys, also the intensity of their utilization, the justifications that put themselves to the base of the use and, therefore, the capacity of the different media to carve on the proceeded of perception and representation of the reality, on the adults and young’s formae mentis, on social and cultural references, to revolutionize the dynamics of socializing and the interaction in and
between generations.
Facing shapes of perception, of reasoning and so different thought aside of the young is inevitable to imagine and to test a new way of education that activates formative strategies with languages and codes near the sensibility of
the new generations (Morcellini, 2007).
The teachers could teach using a different language: that of the young, to know their cultural habits, to observe their behaviors and to include their references values and, at the end, to intervene in their route of life with formative strategies ad hoc, offering them an additional value, that is a different input with that is important to confront itself, to meet itself, to recognize itself or, at least, to appraise. The adult should align itself to the young’s cultural and social universe in order to hope to build cultural bridges of mediation and the first environment in which to intervene is certainly the school. Multimedia Education Master is a high profile post-graduate annual course focused on the emerging fields of media and new technologies. MedMaster is proposed to teachers, educators, professionals in the communication and education fields and it offers a specific training course to test and introduce media education at school and in cultural institutions, no profit organisations and
business companies operating in the field of mass and new media. The Master graduates will be able to operate in an interdisciplinary
context between media and learning processes, offering support in methodological and procedural framework of projects for
education in/to the media
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
ASSESSMENT OF POTENTIAL BIOLOGICAL ACTIVITIES OF CASEINOPHOSPHOPEPTIDES FROM A COMMERCIAL PURIFIED MIXTURE AND FROM GRANA PADANO AND TRENTIN GRANA, AFTER IN VITRO DIGESTION.
Full text linkMilk and dairy products are an excellent source of bioavailable calcium thanks to the presence of casein phosphopeptides (CPPs), that with their phosporylated serines, bind calcium ions, keeping them in a soluble and bio-absorbable state.
Digestion and absorption are limiting steps for the peptide bioavailability; thus the in vitro digestion procedures combined with the use of intestinal cell models allowed to mimic the physiological milieu, where digestion occurs and the interactions between peptides and intestine determine their fate.
The purpose of this PhD thesis was to identify the biological potential of casein phosphopeptides after in vitro digestion. The first step was about the bio accessibility property of a CPP purified mixture using a culture of intestinal human cells. Next step was about the bioactivity study of a complete food containing CPPs, represented by Grana Padano (GP) and Trentin Grana (TN) at 13, 19 and 26 months of ripening.
Present data show that after in vitro digestion, preformed aggregates (CPP + Ca) in a commercially mixture still maintain their conformation and retain their bioactivity as promoters of
calcium uptake in intestinal cells, regardless of calcium mechanism transport (TRPV6 in Caco2 cells and depolarizing L-type calcium channels in HT-29 cells).
GP and TN digestates, were also able to induce a calcium uptake in a co-culture of Caco2 and HT-29, a model of human intestinal epithelium more complete and useful. Moreover, they shown the capacity to induce the bone mineralization in human osteoblast-like cells.
Since the biological potential after digestion was verified, CPPs could be considered as a nutraceutical and GP and TN cheeses as potential functional foods
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
