Video‐analysis of Social Situations: Approaches and Practices
No full textThe tutorial provides a methodical and practical introduction to interpretative video‐analysis. The first part is dedicated to the methods of interpretative video‐analysis. The different existing approaches, like videography, videohermeneutics and video‐interaction‐analysis, are discussed, focussing on its respective underlying methodical principles and its diverse practices of data recording, selection, analysis and interpretation. A wide range of studies, inspired by Ethnomethodology, Sociological Hermeneutics and Genre Analysis, ar reviewed. This includes video‐analysis from workplace‐studies in control‐rooms and emergency‐rooms, the performance of religious visionaries, wedding‐ceremonies, the genre of powerpoint‐presentation

L'Università che vorrei ...analisi delle preferenze espresse dagli operatori con variabili numeriche e testuali
No full textL'introduzione di strumenti di analisi dei dati testuali all'interno della Conjoint Analysis, consente di ottenere gruppi di giudici, sulla base della struttura delle preferenze espresse, sia circa possibili alternative di università, così come appaiono nei dibattiti attuali, sia attraverso descrizioni fornite liberamente. Applicando la strategia proposta in Balbi, Infante Misuraca (2008), si arriva a definire possibili scenari alternativi di università, identificando i sostenitori delle diverse scelte, superando i limiti della rilevazione "full profile
A Doubly Projected Analysis for Lexical Tables
No full textThe presentation aimed at showing how the introduction of external information in analysing a lexical table can enrich interpretation of factorial maps. The methodological frame is given by Principal Component Analysis onto a Reference subspace, a method based on the orthogonal projection of a correlation structure on the space spanned by an external set of explanatory variables. In previous papers, the idea of a projected lexical analysis has been introduced, using a single reference space, where to represent the behaviour of terms, while information on documents were used for building aggregate lexical tables. Here we consider external informative structures both on documents and terms, i.e. on rows and columns of a lexical table. The proposal consists in a double projection strategy, which additionally involves the document behaviour, related to external information. An application on the Italian Universities didactic supply is shown
