Interazione dialogica interculturale on-line. Sviluppo di un modello riflessivo. Webbasierte interkutlurelle dialogische Interaktion. Entwicklung eines reflexiv-orientierten Modells
No full textGoal of this dissertation is to discuss the possibility of using the web for projects of intercultural dialogue.
But what is intercultural dialogue? This work tries to give a scientifical definition of it, through an intensive, multi- and interdisciplinary theoretical discussion which focus on following complex concepts: communication, dialogue, culture and intercultural dialogue as well as identity.
Of particular interest is this work for scientists but also for practicioners, which deal with the conceptualization or facilitation of dialogical projects.Questo lavoro nasce nell'ambito della comunicazione interculturale e assume nel suo percorso prospettive proprie della pedagogia interculturale, nutrendosi inoltre di ricerche originate in ulteriori settori disciplinari (in particolare: psicologia, sociologia, linguistica). La multidisciplinarità che caratterizza questa tesi e che in alcuni passaggi si trasforma in una vera e propria interdisciplinarità, permette un'analisi sfaccettata e il più possibile completa del suo oggetto.
Al centro della ricerca si trova l'interazione dialogica, l'interazione cioè che ruota intorno allo sviluppo del sé tramite l'esperienza dell'altro. Di particolare interesse è per questo studio l'aspetto interculturale che può venire a caretterizzare tale interazione, aumentando la sua complessità a vari livelli. Imprescindibile si delinea dunque l'approfondimento degli ambiti teorici legati al concetto di comunicazione e a quello di cultura.
Alla complessità del processo comunicativo viene dedicata la prima parte della tesi, il cui obiettivo è quello di discernere le diverse variabili che lo influenzano per poterle così analizzare. Il significato di cultura e interculturalità vengono invece discussi nella seconda parte del lavoro, permettendo così di specificare e delineare il significato di interazione dialogica interculturale. L'esplorazione di questo concetto svela la sua fragilità processuale, rendendo così evidente la necessità di creare un ambiente adatto al suo svolgimento, trasformando l'interazione dialogica, in maniera più o meno esplicita, in un percorso di apprendimento riflessivo. L'ideazione e lo svolgimento di progetti didattici orientati alla realizzazione di tali interazioni diventano dunque focus del lavoro di ricerca, il cui campo viene precisato ulteriormente scegliendo il web come campo d'azione. Nella terza e ultima parte della tesi vengono così discusse le variabili che lo rendono uno spazio potenzialmente adatto ad ospitare tali esperienze. Le peculiarità del gruppo di riferimento e i suoi possibili obiettivi dialogici specifici, la figura plurifunzionale del moderatore, la creazione di un'atmosfera di fiducia e l'offerta tecnologica attuale sono tra le dimensioni elaborate che si vengono a incrociare nelle diverse fasi del processo, dalla sua ideazione fino alla valutazione
Carpobrotus acinaciformis vs Carpobrotus edulis: Are there any differences in their impact on coastal dune plant biodiversity?
No full textCoastal sand dunes are widely acknowledged as fragile and dynamic ecosystems. Among the several threats affecting the native biodiversity of these systems, invasive plants are one of the most troubling ones. The genus Carpobrotus has been recognized as one of the most abundant invasive genera along the Mediterranean coast, particularly in coastal sand dunes. In Italy, two taxa belonging to this genus have been identified: C. edulis and C. acinaciformis. Given that the taxonomic identification of these two species is still subject of debate, we investigate whether there are differences concerning their ecology in terms of their impact on native plant communities in central Italy coastal dunes. To do so, we analyzed their relative impact on species richness, diversity and relative abundance. Vegetation sampling was carried out through paired-plots, comparing invaded to non-invaded plots. Although our results show a general decrease in native species richness in all the invaded plots, there were no significant differences between the richness and diversity of the native communities invaded by C. edulis and that of the communities invaded by C. acinaciformis, although slight differences on native species’ relative cover was observed. In addition, we observed a higher occurrence of C. edulis in the areas closer to the seashore. We conclude that even though there are no meaningful differences in the impacts of the two taxa on native biodiversity, further analyses are needed to exclude potential differences in their relative ecological adaptations to the changing abiotic conditions found along the coastal zonation
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
