Il benessere a scuola: sviluppo e risultati di un’inchiesta partecipativa
Full text linkIl contributo presenta i risultati di un’inchiesta tramite questionario sulle condizioni di benessere e disagio a scuola, che ha coinvolto 1389 studentesse e studenti di un Liceo di una città metropolitana dell’Italia settentrionale. Lo strumento d’indagine utilizzato è il prodotto di un processo partecipativo al quale hanno preso parte diverse componenti della comunità scolastica insieme ai ricercatori esterni. Il processo di costruzione ha preso le mosse da un precedente strumento elaborato da un gruppo di studentesse e studenti e ha tenuto conto sia di modelli disponibili nella letteratura di ricerca, sia dei risultati di una indagine esplorativa condotta mediante focus group. Le analisi fattoriali e di scala presentate in questo studio mostrano una struttura multidimensionale del costrutto di benessere che si adatta ai dati raccolti e risulta complessivamente coerente con alcuni studi recenti che ricadono nello stesso ambito. In particolare, il modello proposto considera dieci dimensioni del benessere a scuola, definite come adeguatezza e sicurezza degli spazi fisici, senso di protezione da comportamenti avversi emessi da insegnanti, o da altri studenti, informazione, espressione e partecipazione, rapporto con gli insegnanti, didattica, funzione formativa della valutazione, rapporto con i compagni, soddisfazione per la scelta dell'indirizzo e dell'Istituto. Infine, si presentano alcuni risultati dell’analisi delle differenze significative tra i gruppi secondo l’anno di scolarità, l’occorrenza di debiti formativi e l’identità di genere.This article presents the results of a questionnaire survey on the conditions of well-being and discomfort at school, in which 1389 students from a high school in a large northern Italian city took part. The survey instrument used is the result of a participatory process involving different components of the school community together with external researchers. The construction process started from a previous instrument developed by a group of students and took into account both models available in the research literature and the results of an exploratory study conducted through focus groups. The factor and scale analyses presented in this study show a multidimensional structure of the construct of well-being that fits the data collected and is broadly consistent with a number of recent studies in the same field. In particular, the proposed model considers ten dimensions of wellbeing in school, defined as the adequacy and safety of physical spaces, the feeling of protection from detrimental behaviour by teachers or other students, information, voice and participation, relationship with teachers, teaching methods, formative function of assessment, relationship with peers, and satisfaction with the choice of course and institution. Finally, some results of the analysis of significant differences between the groups according to school year, the occurrence of subject resits, and gender identity are presented
An on-line spreading factor allocation for a LoRaWAN network
No full textLoRaWAN (Long Range Wide Area Network) is an interesting network technology for building ultra low-power instances of the Internet of Things (IoT) and motivated a significant interest in the recent literature. The contribution of this paper is twofold. First, we devise a model to evaluate the performance of algorithms used for assigning the best "resource patterns" to transmit packets on the wireless interface of LoRa; to this end, we adopt a Spatial Point Process to model the distribution of nodes in the system and we apply such a model to derive, in a compact way, the performance of a Spreading Factor allocation mechanism proposed in the literature. A second contribution of the paper consists in the definition of a new metric to estimate the network performance and of a new protocol to dynamically improve the above assignment algorithm. Both the metric and the algorithm are based on a re-transmission mechanism. © 2019 Association for Computing Machinery

No full textValidity and reliability of the Italian version of the Teachers' Sense of Efficacy Scale
Full text linkPurpose: This study investigates the construct validity and reliability of the Italian version of the Teachers' Self-Efficacy Scale (TSES) developed by Tschannen-Moran and Hoy (2001) and contributes to existing research aimed at exploring the elements and variables that influence teachers' self-efficacy levels. Design/methodology/approach: The instrument, translated and adapted in Italian by Cardarello et al. (2017), was tested on a sample of 349 in-service second grade teachers with similar demographic profiles (gender, age, seniority). The study analyzes the data following the exploratory factor analysis. Findings: The results of this research confirm the relevance of the three-factor model, but opens the possibility of a different organizational structure of the items within the scale. In fact, the results confirmed both the original TSES three-factor structure (student engagement, classroom management, instructional strategies) and a new four-factor structure. The new four-factor structure recognizes two new factors of an instructional nature, “Inclusive instructional strategies, learner-centered” and “Traditional instructional strategies, teacher-centered.” The first one recalls beliefs about capabilities to use strategies and assessments focused on students' needs (inclusive perspective); the second one refers to the dimension of the disciplinary master. Originality/value: According to the idea that teachers' self-efficacy is a multidimensional construct, the findings of this study invite to reflect upon the meanings of scale application in different cultural contexts and open a discussion about instructional strategies and the experience of teaching in Italy
Percezione di efficacia nella scuola secondaria presso insegnanti curricolari e di sostegno
No full textSi riportano i dati di un'indagine. La ricerca verte sui livelli di efficacia percepita da un campione (356) di insegnanti della scuola secondaria, di primo e di secondo grado, intervistati attraverso la cosiddetta 'scala dell'Ohio' e confronta i profili degli insegnanti curricolari e degli insegnanti di sostegno
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
