Creación de un modelo estadístico predictivo para la determinación de las funciones de atenuación en español hablado
2018
Recientemente, algunos autores han definido distintas variables para caracterizar la atenuación lingüística en el marco de una base de datos multidimensional (Briz/Albelda; Albelda/otros). En este estudio se han seleccionado 982 elementos de atenuación de dieciocho entrevistas de español hablado; todos ellos han sido supervisados por hasta cuatro entrevistadores del proyecto Es.VaG.Atenuación. Finalmente, los datos se han evaluado mediante tres pruebas estadísticas para la clasificación y la reducción de variables: el análisis múltiple de correspondencias, el árbol de clasificaciones y el Random Forest. Las variables más determinantes en la discriminación de las funciones de atenuación han …

On methods of access to the structure of social representations: the example of Europe.
2012
espanolEl objetivo de este estudio es identificar la logica detras de una serie de metodos estadisticos utilizados para revelar la estructura de las representaciones sociales. Se solicito a un numero de sujetos (n = 317) responder a la pregunta siguiente: �Para cada categoria de europeo, por favor indique con que otros europeos le gustaria tener contacto�. Los resultados de los analisis de similitud nos llevan a la conclusion de que existe un sesgo etnocentrico, y revelan el factor central de la representacion. La representacion obtenida por el analisis factorial de correspondencias se parece mas a la realidad actual y nos permite entender las divisiones que han estructurado Europa y perman…
Visualizing knowledge and attitude factors related to influenza vaccination of physicians
2014
To characterize groups of primary healthcare physicians according to sociodemographic data, years of professional experience and knowledge of and attitudes to influenza, and to evaluate differences between groups with respect to influenza vaccination in the 2011-2012 season.We carried out an anonymous web survey of Spanish primary healthcare physicians in 2012. Information on vaccination, and knowledge of and attitudes to influenza was collected. Multiple correspondence analysis and cluster analysis were used to define groups of physicians.We included 835 physicians and identified three types. Type B were physicians with low professional experience of influenza. Types A and C were physician…
Ocular pulse amplitude in patients with open angle glaucoma, normal tension glaucoma, and ocular hypertension.
2002
Intraocular pressure (IOP) is not a fixed constant value but rather has pulsatile components associated with cardiac action. The SmartLens dynamic observing tonometer (odc, Ophthalmic Development Company AG, Zurich, Switzerland) can measure and record simultaneously IOP and ocular pulse amplitude (OPA). It was the aim of this study to evaluate OPA in patients with primary open angle glaucoma (POAG) and high IOP, normal tension glaucoma (NTG), and ocular hypertension (OHT). Furthermore, the authors examined whether there were any correlations with blood pressure.80 subjects were divided into four groups (n=20): 20 patients each with POAG, NTG, and OHT and 20 volunteers without any ocular pat…
The dimensions of mobilities: The spatial relationships between corporeal and digital mobilities
2013
Abstract The aim of this article is to study how the corporeal and digital mobilities are spatially organised in relation to each other in everyday life. The dimensions of mobilities are modelled by using survey data (N = 612) collected from Finland in 2011, Multiple Correspondence Analysis (MCA) and Multiple Regression Analysis (MRA). The results show that the combined use of corporeal and digital means of mobility affect the spatial organisation of mobilities only little. The results indicate that young people and students are more likely to benefit from their mobility in networking activities as they are equipped with a larger variety of mobility means than older people and pensioners. L…
Italian Amateur Pop-Rock Musicians on Facebook: Mixed Methods and New Findings in Music Making Research
2017
This chapter investigates how and why amateur musicians use social networking sites, employing a mixed-methods approach. Attention is focused on four big Italian Facebook communities of pop-rock musicians: drums, bass, guitar, and keyboard players (overall, 2,101 active users), analyzing the relational and textual data extracted from the web. The chapter analyzes the network structures emerging from the interactions among the users. It also identifies and maps the main areas of discussion (sound shaping, studio recording, marketplace, musical references, computer production, and relations) and the latent semantic dimension characterizing Facebook users’ activities, through social network an…
Psicodinamiche di convivenza nel gruppo di lavoro: un'indagine esplorativa
2009
Psicodinamiche di convivenza nel gruppo di lavoro: un'indagine esplorativa - This work is focused on the study of psychodynamics of cohabitation in work groups, organizations and institutions. The generic aim is to explore the relations between organizational feelings and work group efficacy. The research has been carried out with a group of 120 Sicilian workers. In the present study we considered organizational commitment, justice, trust and power feeling. The multiple correspondence analysis point out two dimensions called: Collusion/Collusion Failed and Adhesive Professional Identity/Repulsive Professional Identity. The results point out relations between middle scores of organizational …
Exploring automatic grouping procedures in ceramic petrology
2004
Although a small number of studies have attempted to introduce automatic grouping procedures into thin section petrography of archaeological ceramics, the majority of studies continue to be carried out by non-automatic means. Although such an approach with the single observer grouping samples has a number of advantages, it is problematic when dealing with large numbers of samples. This paper aims to explore different coding systems and statistical analyses for grouping ceramic thin sections. In the example discussed a number of variables are defined, codified and analysed by correspondence analysis, classical multidimensional scaling, non-metric isotonic multidimensional scaling and Sammon …
Tra «pentoloni per il solfato ammonico» e «un numero inverosimile di tubi»: le lettere di Carlo Emilio Gadda all’Ammonia Casale
2022
The essay analyzes the correspondence between Carlo Emilio Gadda and the "Ammonia Casale S.A." which intermittently covers a period from April 1927 to January 1940, with a long break between the autumn of 1931 and the spring of 1936. It is a decisive period of time on the public and private level. Reading the correspondence allows you to retrace an entire page of the history of Italian industry under fascism from an eccentric perspective.
