Media education and healthy nutrition: A training experience with teachers and students
No full textThis article briefly presents a training experience offered to primary and
secondary school teachers and their students, within the research field
born from the convergence of media education and health education.
The article aims at outlining this field, from which the transversal and
flexible nature of media education and its theoretic and methodological
potential to cross different study perspectives emerge
Promuovere la salute attraverso l'educazione mediale: una ricerca quasi-sperimentale con bambini di 10 anni e i loro genitori
Full text linkThis research pertains to the broad study field of “Health Promoting Media Literacy Education” (Bergsma & Carney, 2008; Bergsma & Ferris, 2011) and regards in particular children's healthy nutrition (Evans et al., 2006; Tanner et al. 2008).
The purpose of this pilot study was to evaluate the effectiveness of a school-based media education intervention on the promotion of fruit and vegetables consumption to prevent childhood obesity. The target population for the study was 10-year-old Italian children and their parents. The study utilized a mixed-method approach, with a quasi experimental design (one intervention group – 27 children and one of their parents – and one control group – 33 children and one of their parents), integrated by a focus group, which is used as a key for the interpretation of the quantitative data.
Pre-test, post-test (upon completion of the intervention) and delayed post-test (after 3 months upon completion of the intervention) measured: the children's fruit and vegetables consumption, motivation, self-efficacy and parental social support related to fruit and vegetables consumption; parent motivation and social support related to their children fruit and vegetables intake; availability and accessibility of fruit and vegetables at home.
Upon completion of the intervention, a focus group was conducted with children in the intervention group, divided in three different groups. During the focus group, children were asked to express their health and media beliefs and knowledge, their ability of critical analyses and expression skills, and nutritional behavior intentions, as well as their opinions/satisfaction with the intervention.
The 10 weeks long intervention included 12 sessions on: health education, media literacy, and a health communication media-based campaign workshop during which the children created posters, newsletters and video commercials on fruit and vegetables targeted to their parents.
To test the intervention effect on the changes in outcomes of all variables, independent sample T-test analyses were calculated. The intervention was effective in increasing children’s fruit and vegetable intake (p<.05) and all psychosocial determinants (p values ranging from 0.00 to 0.04) both at immediate post-test and at delayed post-test. Parents reported increased emotional social support (p<.05) at delayed post-test.
To investigate the families raised from the focus group text, the content analysis was done. The relationship among the families was investigated with the co-occurrences analysis, from which the ability of expression - that is one of the main skills stimulated by the media education (production approach) - results in the central core of the relationship among almost all of the theoretical constructs investigated, so we could consider it the main successful factor of the intervention.
These results indicate that a nutrition and media literacy intervention may be an innovative and promising methodological approach to promote children’s healthy nutritio
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
Italian children perceptions and intentions about health and healthy eating: A focus group study
No full textThe purpose of this study was to investigate the effectiveness of a school-based media education curriculum on the promotion of fruit and vegetables consumption to prevent childhood obesity. The target population for the study was 10 years old Italian children (n=60) and their parents. The study utilized a mixed-method approach, with a quasi experimental design (with one intervention group and one control group). During pre-test and post-test and delayed post-test (after three months), psychosocial determinants (i.e. self efficacy, motivation, parental support ) and fruit and vegetable intake were measured. Upon completion of the intervention, focus groups were conducted with children in the intervention group. During the focus group, children were asked to express their health and media beliefs and knowledge, and nutritional behavior intentions, as well as their opinions/satisfaction with the intervention. The purpose of this presentation is to present the results from the focus groups. 21 children (7 female and 14 male) participated in 3 focus groups. The focus groups were recorded and transcribed. The transcripts are currently being coded and analyzed following standard qualitative analyses protocol. Data interpretation will be completed by the end of May 2012
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
