Quantities, determinants, and awareness of households' food waste in Italy: A comparison between diary and questionnaires quantities
Full text linkFood waste at the household level accounts for a significant share of total food waste in developed economies, according to the Food and Agriculture Organization. Studies have shown that this share varies between 0.3 kg to 4.5 kg per person per week, depending on the definitions and methodologies applied. In Italy, quantities, behaviors, and attitudes regarding food waste have been solely explored through the use of questionnaires, typically leading to discrepant values of food waste. In this study, we estimate and analyse the determinants of food waste over a 388 units' panel spread over the national territory, through a diary and questionnaire study. Moreover, by comparing food waste value that was declared in questionnaires and reported in diaries, we confirm that the awareness of food waste quantities is heavily biased. The results confirm that the average food waste value is significantly higher when gathered through diaries, while questionnaires are able to catch less than one-third of food waste determinants
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
Covid-19 e studenti UNIMORE: come l’emergenza cambia lo studio e l’esperienza universitaria
Full text linkIl rapporto di ricerca presenta i risultati della rilevazione online condotta dall'Università degli studi di Mo-dena e Reggio Emilia sulle condizioni di vita e di studio degli studenti nel periodo 8 aprile – 2 maggio 2020. Alla rilevazione on line ha risposto il 20% degli studenti: un tasso di partecipazione adeguato per cogliere alcune significative differenze tra corsi di studio. L'indagine ha come obiettivo quello di superare l'emergenza Covid-19 con maggiore consapevolezza, analizzando le condizioni di vita e di studio degli studenti e cercando gli strumenti più utili a una didattica inclusiva e a uno studio che contribuisca a dare a ogni studente la possibilità di procedere nel proprio percorso di studi e nel proprio percorso di vita nel migliore dei modi. Vengono presentati il questionario, gli strumenti di rilevazione e i risultati che emergono dall'analisi multivariata, sia per quel che riguarda le domande a risposte chiuse sia per le domande aperte, su cui sono state applicate tecniche di analisi testuale. Le diverse tecniche di analisi sono presentate per enfatizzare la specificità del dataset che presenta un differente livello di variabilità delle risposte nei diversi ambiti tematici. Il rapporto si conclude con una serie di considerazioni che offriamo alla comunità di Uni-more per supportare la discussione su quanto abbiamo appreso e continuiamo ad apprendere grazie alla voce degli studenti. È ormai chiaro che l'uscita dall'emergenza sarà un processo graduale. Il punto di vista degli studenti, che cogliamo da questa rilevazione, sarà davvero prezioso per progettare le attività didattiche e i servizi agli studenti del prossimo anno, per offrire una didattica di qualità che risponda alle diverse esigenze e ai diversi contesti di studio. Ulteriori sviluppi dell'analisi potranno riguardare altri approfondi-menti sulle specifiche modalità di didattica (a distanza e in presenza) e sulla valutazione delle condizioni di vita e di lavoro del personale docente e tecnico-amministrativo. L'idea di fondo è quella di leggere, attraverso la lente dell'emergenza Covid-19, le dimensioni essenziali per migliorare la qualità della didattica evidenziate dalla rilevazione empirica.The research report presents the results of the online survey conducted by the University of Modena and
Reggio Emilia on the living and study conditions of students in the period 8 April - 2 May 2020. The online
survey was answered by 20% of students: an adequate participation rate to capture some significant differences between courses of study. The aim of the survey is to overcome the Covid-19 emergency with greater
awareness, analysing the living and study conditions of the students and looking for the most useful tools
for inclusive teaching and study that contribute to giving each student the possibility to proceed in their
own study and life path in the best possible way. The questionnaire, the survey tools and the results that
emerge from the multivariate analysis are presented, both for the closed-answer questions and for the openended questions, on which textual analysis techniques have been applied. The different tools and methods
are presented to emphasize the specificity of the dataset, which presents a different level of variability of
the answers in the different thematic areas. The report concludes with a series of considerations that we
offer to the Unimore community to support the discussion on what we have learned and continue to learn
thanks to the voice of the students. It is now clear that the exit from the emergency will be a gradual process.
The students' point of view, which we gather from this survey, will be really valuable to plan next year's
educational activities and services for students, in order to offer a high quality teaching that responds to
different needs and study contexts. Further developments of the analysis may concern other in-depth studies
on specific teaching methods (distance and in-presence) and on the evaluation of the living and working
conditions of teaching and technical-administrative staff. The basic idea is to read, through the Covid-19
emergency lens, the essential dimensions to improve the quality of teaching highlighted by the empirical
surve
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
