Looking for “the one”: who is the “real” opinion leader in an agricultural cooperative?
No full textThe aim of the chapter is to answer a critical question: how do we identify an opinion leader portrait in agriculture (specifically in a cooperative)? A key point of concern is the profile of these people in terms of the leading features and some other characteristics which will help policy makers and local stakeholders to identify and use them in the agricultural extension work. In order to achieve the above-mentioned aim a field - case study - research was carried out in a typical Greek agricultural cooperative
Socio-economic study of adoption factors in a novel product of the agri-food sector
No full textThis thesis focused on exploring the acceptance and the adoption of a novel food product derived by agri-food industrial by-products. Specifically, the main aim was achieved through three scales: a) the Food Neophobia Scale (FNS), b) the Food Technology Neophobia Scale (FTNS) and c) the Domain-Specific Innovativeness Scale (DSI), combined with a case study based on a hypothetical scenario in the metropolitan area of Thessaloniki. For this purpose, a qualitative research was conducted initially followed by a quantitative analysis of 384 one-to-one interviews. The data was collected, and information was evaluated through descriptive statistics and multivariate statistical analyses. In particular, a Two-Step Cluster Analysis was used in combination with Categorical Regression for the classification of the sample in clusters depending on the level of innovativeness and the level of neophobia and technophobia. Then, the sample was divided into clusters with common characteristics and behavior in order to examine the compatibility with Rogers' theory and to describe the profile of potential final users of the novel food product, as well as the factors for its acceptance or rejection. This research was co-funded by the European Union’s Horizon 2020 Research and Innovation Programme «Sybawhey-Industrial symbiosis for valorizing whey and banana wastes and by-products for the production of novel foods», in the framework of Marie Skłodowska-Curie (MSCA) - RISE 2015 action.Η παρούσα διατριβή επικεντρώθηκε στη διερεύνηση της αποδοχής και της προθυμίας υιοθέτησης ενός καινοτόμου προϊόντος από τα υπολείμματα του αγροδιατροφικού κλάδου. Συγκεκριμένα, ο κύριος στόχος της διατριβής επετεύχθη μέσα από τη μελέτη τριών κλιμάκων: α) της Κλίμακας Νεοφοβίας των Τροφίμων (Food Neophobia Scale-FNS), β) της Κλίμακας Νεοφοβίας της Τεχνολογίας των Τροφίμων (Food Technology Neophobia Scale-FTNS) και γ) της Κλίμακας Καινοτομικότητας (Domain-Specic Innovativeness-DSI), σε συνδυασμό με την ανάλυση μίας μελέτης περίπτωσης η οποία βασίστηκε σε ένα υποθετικό σενάριο. Για το σκοπό αυτό πραγματοποιήθηκε δειγματοληπτική έρευνα στο Πολεοδομικό Συγκρότημα Θεσσαλονίκης. Αρχικά διενεργήθηκε ποιοτική έρευνα, κι έπειτα, ποσοτική ανάλυση με 384 προσωπικές συνεντεύξεις. Τα δεδομένα που συγκεντρώθηκαν και το λοιπό υλικό αξιοποιήθηκε και επεξεργάστηκε με Απλές Περιγραφικές αλλά και με Πολυμεταβλητές Στατιστικές Αναλύσεις. Ειδικότερα, εφαρμόστηκε Διβηματική Ανάλυση σε Συστάδες (Two-Step Cluster Analysis) για την τμηματοποίηση του πληθυσμού σύμφωνα με το βαθμό καινοτομικότητας και το βαθμό νεοφοβίας και τεχνοφοβίας του πληθυσμού. Ακολούθως, τμηματοποιήθηκε το δείγμα σε ομάδες με κοινά χαρακτηριστικά και συμπεριφορά προκειμένου να εξεταστεί η συμβατότητα με τη θεωρία υιοθέτησης καινοτομιών του Rogers και περιεγράφηκε το προφίλ των δυνητικά τελικών χρηστών του καινοτόμου προϊόντος καθώς επίσης μελετήθηκαν οι παράγοντες αποδοχής ή απόρριψης του καινοτόμου προϊόντος. Σε κάθε εφαρμογή της Διβηματικής Ανάλυσης σε Συστάδες εφαρμόστηκε το μοντέλο της Κατηγορικής Παλινδρόμησης (Categorical Regression) προκειμένου να διερευνηθεί η σχέση μεταξύ των δημογραφικών και λοιπών χαρακτηριστικών και της εκάστοτε τμηματοποίησης. Η παρούσα διατριβή συγχρηματοδοτήθηκε από το Ευρωπαϊκό Ερευνητικό Πρόγραμμα “Sybawhey-Industrial symbiosis for valorising whey and banana wastes and by-products for the production of novel foods”, στο πλαίσιο της δράσης Marie Skłodowska-Curie (MSCA)-RISE 2015
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
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
