Taste and watch for an aware food consumption in the school
No full textMonitor school meals and students’ appreciation, promoting
awareness about food use/waste, in relationship with breakfast and morning snacks.
Determine approval rating, and measure food waste in school, to develop strategies for management and education about prevention and reduction of food waste.
Methods
To control the food waste in school, it was developed a collaboration between healthcare (SIAN, Bologna’s USLgency), education (school) and society (parents, scholastic foodservice and administration).
Two surveys were prepared about the appreciation and consumption of provided meals, breakfast and morning snacks, and a hundred 3rd and 4th grade children participated. Bread and fruit leftovers were used as snacks or given to charity.
Each phase of the project was video taped to show participation of all parties. The results were discussed with all the participants while planning for following school years.
Results
2069 nutritional profiles were examined (breakfast, snack, and lunch). The consumption of first (pasta) and second (meat or fish) courses was 3/4, while vegetables, breads, and fruits, was 1/2. Those who had a proper breakfast and/or morning snack tended to eat a greater quantity of food for lunch.
Some differences emerged between the two schools involved. In one school there was significantly higher meal consumption, with a two-fold difference for vegetables, second dishes and fruits. The difference between schools with equal socio- economic status, seemed to be due to the active and authoritative teachers.
Conclusions
The surveys were simple and well accepted by the children. They actively participated with enthusiasm, and they were awarded with the title of ‘‘little tasters’’.
The joint planning between the education, healthcare, and social components will continue: it will start a project for all the schools of Bologna to promote the consumption of proper snacks (fruits), and to monitor food waste, in order to guide both nutritional education interventions.
Key messages:
Scholastic food service is a very important occasion to promote nutritional education and an healthy diet.
To succeed, is fundamental the active involvement of children, teachers, parents, scholastic foodservice and healthcare, to balance between offering healthy food and maximizing customer satisfaction
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
Comparative study on the efficiency of peracetic acid and chlorine dioxide at low doses in the disinfection of urban wastewaters
Full text linkA comparison was made between the efficiency of low closes of peracetic acid (PAA: 1.5 mg/l) and chlorine dioxide (ClO2,: 1.5 and 2.0 mg/l) in the disinfection of secondary effluents of a wastewater treatment plant. Peracetic acid was seen to be more active than chlorine dioxide and less influenced by the organic content of the waste. Both PAA and ClO2, (2.0 mg/l) lead to a higher reduction in total and faecal coliforms and E. coli than in phages (somatic coliphages and F-specific RNA bacteriophages) and enterococci. Detection of faecal coliforms and E. coli should therefore be accompanied by a search for these more resistant microorganisms when assessing the conformity of wastewater for irrigation use, or for discharge into surface waters. Coliphages are also considered suitable indicators of the presence of enteric viruses. Although the application of low doses of both disinfectants offers advantages in terns of costs and produces not significant quantities of byproducts, it is not sufficient to obtain wastewater suitable for irrigation according to the Italian norms (E. coli < 10/100 ml in 80% of samples and <100/100 ml in the remaining samples). Around 65% of the samples, however, presented concentrations of E. coli lower than the limit of 5,000/100 ml established by Italian norms for discharge into surface waters
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
