    Il lavoro si pone l’obiettivo di analizzare la relazione tra il clima scolastico e i risultati degli studenti italiani. Vengono utilizzati i micro-dati raccolti dall’INVALSI nell’ambito del Sistema nazionale di valutazione relativi all’a.s. 2015-16. Sulla base dei modelli a equazioni strutturali si cerca di evidenziare il ruolo che svolge il clima scolastico nel sistema di relazioni che intercorre tra i risultati degli studenti della II secondaria superiore e una serie di fattori scolastici con particolare riferimento a quelli di natura socio economica. I principali risultati mettono in luce che il clima, soprattutto sotto il profilo dei comportamenti disciplinari, svolge un duplice ruolo: da un lato influenza in modo diretto il livello medio di competenza degli studenti, dall’altro è in grado di mediare l’effetto del background socio-economico in cui opera la scuola

    Numerosi studi hanno evidenziato l’importanza delle competenze finanziarie nel determinare il benessere economico delle famiglie e la necessità che queste competenze vengano acquisite sin dall’età adolescenziale. In questa ottica, il lavoro utilizza i dati per i Paesi che hanno partecipato all’ultima edizione dell’indagine OECD PISA (2015) sulla financial literacy per valutare: i) il grado di diffusione delle esperienze con il denaro tra gli adolescenti; ii) l’effetto di queste esperienze sul livello di competenza finanziaria. Dal punto di vista metodologico, attraverso l’analisi delle corrispondenze multiple si costruisce un indicatore sintetico di diffusione delle esperienze con il denaro. Successivamente per ogni Paese si valuta l’effetto di tale indicatore sia sul punteggio medio in financial literacy attraverso regressioni OLS sia lungo l’intera distribuzione del punteggio attraverso regressioni quantiliche. Infine, si studia l’eterogeneità di tali effetti tra Paesi. I principali risultati mettono in luce che nella maggior parte dei Paesi l’esperienza finanziaria gioca un ruolo importante nel favorire l’acquisizione delle competenze finanziarie e suggeriscono che programmi educativi basati su approcci esperienziali (ad esempio gli stock market games) possono essere dei validi strumenti di policy per elevare il livello di alfabetizzazione finanziaria della popolazione

    Multidimensional poverty measures for analysingeducational poverty in European countries Tommaso Agasisti*, Sergio Longobardi†, Vincenzo Prete‡, Felice Russo§AbstractThis paper studies the degree of educational poverty in European countries by focusing on data from two editions of the OECD Programme for International Student Assessment (PISA): 2006 and 2015. We focus on students’ proficiency levels in various literacy domains andpropose a multidimensional approach that enables the measurement of not only the incidence of educational poverty but also its depth and severity. Subsequently, we perform a micro-econometric analysis of school factors that are associated with the probability of educational poverty using a Partial Proportional Odds Model. The main results demonstrate that in recent years, the incidence of educational poverty became more relevant in many countries, while most of them experienced a reduction of poverty depthand severity. Several school factors can be manipulated to avoid the trap of educational poverty, such as improving the disciplinary climate, adopting an adaptive style of teaching, and increasing the amount of instructional time

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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
