Italian adaptation of the Group Questionnaire: validity and factorial structure
2020
The Group Questionnaire (GQ) is a measure recently developed by Krogel et al. (2013) for the evaluation of the therapeutic relationship in group. The GQ identifies a three-factor model of the relationship that allows to measure quality (Positive Bonding, Positive Working and Negative Relationship) and structure (member-member, member-leader and member-group), dimensions in group. This work shows the results of a first study on the Italian validation of the GQ. In this study the GQ was administered to 536 subjects from 32 non-clinical groups of undergraduate students. The cross-cultural validity of the GQ in the Italian population has been examined by comparing the psychometric properties an…
Remote sensing and climate data as a key for understanding fasciolosis transmission in the Andes: review and update of an ongoing interdisciplinary p…
2006
Fasciolosis caused by Fasciola hepatica in various South American countries located on the slopes of the Andes has been recognized as an important public health problem. However, the importance of this zoonotic hepatic parasite was neglected until the last decade. Countries such as Peru and Bolivia are considered to be hyperendemic areas for human and animal fasciolosis, and other countries such as Chile, Ecuador, Colombia and Venezuela are also affected. At the beginning of the 1990s a multidisciplinary project was launched with the aim to shed light on the problems related to this parasitic disease in the Northern Bolivian Altiplano. A few years later, a geographic information system (GIS…
Valutazione e feedback: la competenza docimologica come competenza comunicativa. Una ricerca con i docenti della scuola secondaria
2021
La competenza docimologica degli insegnanti costituisce uno dei perni dell’azione didattica allorché essa può costituire, di fatto, una molla per la promozione dell’apprendimento, dell’autonomia e del successo formativo di ogni alunno. Il feedback, inteso come strumento privilegiato nell’esercizio della prassi valutativa, offre l’opportunità di valorizzare la singolarità dei percorsi di ogni studente intelaiando interazioni comunicative volte alla co-costruzione di conoscenza. La competenza docimologica degli insegnanti assume, pertanto, i connotati della competenza comunicativa, la quale sostanzia e orienta le scelte valutative diversificando registri linguistici e scelte degli strumenti d…
Psicología ambiental y ecopsicología en edad evolutiva: aspectos cognitivos, afectivos y relacionales
2020
Ecopsicología y psicología ambiental estudian la relación individuo-medio ambiente, poniendo de relieve los efectos beneficiosos que el contacto con la naturaleza puede generar en los sujetos a nivel cognoscitivo, afectivo, individual y relacional.Los objetivos que la investigación se ha propuesto conseguir son: explorar las relaciones y vivencias que los niños tienen con respecto a las plantas, espacios abiertos naturales y animales; desarrollar el sentido de pertenencia al territorio; evaluar la percepción del grado de conexión con la naturaleza; evaluar si el contacto con la naturaleza modifique y facilite procesos de aprendizaje, modalidades relacionales; ofrecer un espacio lúdico recre…

Evidencias de validez interna de un instrumento para evaluar la colegialidad docente
2019
Este estudio es parte de una investigación más amplia que busca diseñar un modelo de evaluación de los sistemas educativos basado en la mejora de la cohesión social. Se trata de un estudio de validación métrica de un instrumento de evaluación de la colegialidad docente. El instrumento se aplicó a partir de las conclusiones del estudio de validación por comités de expertos. La muestra estuvo formada por 147 profesores voluntarios de primaria y secundaria de España. La metodología utilizada se basó en la recogida de evidencias métricas de validez interna del instrumento; se estudió la dimensionalidad mediante el análisis factorial exploratorio y la capacidad de discriminación mediante el anál…
Equity valuation in practice: The influence of net financial expenses
2014
Abstract This study investigates the relevance of net financial expenses with respect to equity valuation in an IFRS accounting regime. According to the residual earnings valuation model, income related to balance sheet items that are recorded at fair value is not applicable for valuation purposes. There are no residual earnings associated with these items because the balance sheet provides ‘perfect’ value estimates for the items in question. In accordance with the contention that under IFRS, aggregate net financial liabilities are recorded at a book value that is close to fair value, this study demonstrates that net financial expenses are not associated with the market prices of stocks. Th…
Venture Capitalists’ Appraisal of Investment Projects: An Empirical European Study
1997
The Investment appraisal and valuation process of venture capitalists includes Information gathering, the assessment of risk and required return, and the choice of a valuation method. This process is empirically studied in the United Kingdom, the Netherlands, Belgium, and France. The Importance of different information sources is equal in the four countries, except that the French venture capitalists Place more emphasis on personal references and the track record of the entrepreneur. The required return is lowest in the Netherlands and Belgium for every development stage of a company, and highest in the UK. The most widely used valuation method in the UK is the multiplication of past or fu…
Extreme value theory versus traditional GARCH approaches applied to financial data: a comparative evaluation
2013
Although stock prices fluctuate, the variations are relatively small and are frequently assumed to be normally distributed on a large time scale. But sometimes these fluctuations can become determinant, especially when unforeseen large drops in asset prices are observed that could result in huge losses or even in market crashes. The evidence shows that these events happen far more often than would be expected under the generalised assumption of normally distributed financial returns. Thus it is crucial to model distribution tails properly so as to be able to predict the frequency and magnitude of extreme stock price returns. In this paper we follow the approach suggested by McNeil and Frey …
Application of Operator Splitting Methods in Finance
2016
Financial derivatives pricing aims to find the fair value of a financial contract on an underlying asset. Here we consider option pricing in the partial differential equations framework. The contemporary models lead to one-dimensional or multidimensional parabolic problems of the convection-diffusion type and generalizations thereof. An overview of various operator splitting methods is presented for the efficient numerical solution of these problems.
