L’Analytic Network Process nei processi di trasformazione urbana. Un caso studio a Palermo come occasione per alcune considerazioni teorico-applicati…
2015
Le valutazioni multidimensionali costituiscono un valido strumento a supporto del processo decisionale in risposta a quesiti di tipo diverso (problem solving, ranking, sorting, designing). In particolare, quando i quesiti sono riferiti alle trasformazioni urbane e territoriali, le valutazioni multidimensionali: sono in grado di rappresentare la complessità degli elementi coinvolti a diversi livelli (ad es. ambientale, economico, finanziario, culturale e sociale); facilitano l’esplicitazione dei nodi di conflittualità o di convergenza della pluralità di soggetti portatori di differenti sistemi di valori, di obiettivi e di conoscenze tecniche; rendono trasparenti e ripercorribili tutte le fas…
L’uso del WHOQOL-BREF e dello EUROP-ASI nell’assessment dei disturbi da uso di sostanze: un’indagine comparativa
2010
Lo scopo del presente contributo è rintracciare, attraverso alcuni dati di ricerca, l’esistenza di correlazioni significative tra i punteggi compositi delle diverse aree dello EuropASI e le sezioni della forma breve del WHOQOL in pazienti con disturbo da uso di sostanze, con l’obiettivo di osservare le relazioni esistenti tra l’autovalutazione del benessere soggettivo e la valutazione degli operatori sulla gravità dei problemi connessi alla dipendenza da sostanze. La ricerca ha coinvolto un gruppo di 30 pazienti afferenti ad un Ser.T. del Distretto 13 della AUSL 6 di Palermo. I pazienti sono stati selezionati random, secondo i seguenti criteri di inclusione: diagnosi di dipendenza da sostan…
The role of olfaction in the elaboration and use of the Chardonnay wine concept
2005
The existence of a Chardonnay wine concept was explored in two experiments. In the first experiment, 28 Chardonnay wine experts assessed in terms of a score the degree of representativeness of 48 white wines according to their own Chardonnay wine concept. The samples were 29 wines made from Chardonnay grapes and 19 wines made from other grape varieties (Aligote, Melon de Bourgogne, Sylvaner, Sauvignon blanc, Chenin, Marsanne and Pinot blanc). Two assessment conditions were conducted: orthonasal and global (orthonasal plus retronasal and mouthfeel perceptions). Globally, scores were higher for Chardonnay wines than for non-Chardonnay ones and the consensus among experts demonstrated the exis…
Conceptual vs. perceptual wine spaces: Does expertise matter?
2008
Abstract This study explores the differences in wine categorization between wine experts and novice wine consumers using 10 Melon de Bourgogne (MB) and 10 Chardonnay (CH) wines. Participants performed a free sorting task based on odor similarity followed by a CH and a MB typicality rating task and a liking rating. All tasks were performed orthonasally. We observed a clear agreement between experts concerning typicality scores. Moreover, despite a slight overlap we found a clear differentiation between CH and MB for experts’ typicality scores. For novices, no such agreement on typicality scores was observed and we found a complete overlap between both types of wines. These results suggest th…
Multidimensionality in host manipulation mimicked by serotonin injection.
2014
Manipulative parasites often alter the phenotype of their hosts along multiple dimensions. ‘Multidimensionality’ in host manipulation could consist in the simultaneous alteration of several physiological pathways independently of one another, or proceed from the disruption of some key physiological parameter, followed by a cascade of effects. We compared multidimensionality in ‘host manipulation’ between two closely related amphipods, Gammarus fossarum and Gammarus pulex, naturally and experimentally infected with Pomphorhynchus laevis (Acanthocephala), respectively. To that end, we calculated in each host–parasite association the effect size of the difference between infected and uninfect…
Mixed Driven Refinement Design of Multidimensional Models based on Agglomerative Hierarchical Clustering
2015
20 pages; International audience; Data warehouses (DW) and OLAP systems are business intelligence technologies allowing the on-line analysis of huge volume of data according to users' needs. The success of DW projects essentially depends on the design phase where functional requirements meet data sources (mixed design methodology) (Phipps and Davis, 2002). However, when dealing with complex applications existing design methodologies seem inefficient since decision-makers define functional requirements that cannot be deduced from data sources (data driven approach) and/or they have not sufficient application domain knowledge (user driven approach) (Sautot et al., 2014b). Therefore, in this p…
Local dimensionality reduction within natural clusters for medical data analysis
2005
Inductive learning systems have been successfully applied in a number of medical domains. Nevertheless, the effective use of these systems requires data preprocessing before applying a learning algorithm. Especially it is important for multidimensional heterogeneous data, presented by a large number of features of different types. Dimensionality reduction is one commonly applied approach. The goal of this paper is to study the impact of natural clustering on dimensionality reduction for classification. We compare several data mining strategies that apply dimensionality reduction by means of feature extraction or feature selection for subsequent classification. We show experimentally on micr…
Adaptation of a German Multidimensional Networking Scale into English
2011
Networking refers to building and maintaining personal contacts in order to obtain resources that, in turn, enhance one’s career success and work performance. This study reports the translation and adaptation of a multifaceted German networking scale ( Wolff & Moser, 2006 ) into English and focuses on the equivalence of the two language versions. Going beyond the often used translation-backtranslation method, we used a parallel translation-backtranslation method in combination with two expert committees to arrive at the English scale version, aiming to obtain at least structural equivalence. We utilize a bilingual sample (N = 76) as well as monolingual samples from the US (N = 174) and…
Model wielowymiarowej profilaktyki pozytywnej w teorii i praktyce pedagogicznej
2019
Artykuł opisuje teoretyczne oraz empiryczne założenia autorskiego modelu wielowymiarowej profilaktyki pozytywnej. Ponadto prezentuje sposób jego urzeczywistnienia w praktyce pedagogicznej, przedstawiając strukturę autorskiego programu profilaktycznego Wsparcie wielowymiarowego rozwoju młodzieży, zrealizowanego wśród wychowanków Domu Dziecka w Chmielowicach. Teoretyczne podstawy modelu odnoszą się do teorii głównych i teorii szczegółowych. Natomiast założenia empiryczne sprowadzają się do metodyki konstruowania programów profilaktycznych, a więc kryteriów doboru i metod oddziaływań profilaktycznych, uczestników oraz strategii ewaluacyjnej. Model wielowymiarowej profilaktyki pozytywnej w prak…
Historia del concepto de especie en biología
2021
Resumen basado en el de la publicación Resumen en inglés Se aborda el problema más antiguo y más frustrante en biología, el problema de las especies. Cubre la evolución del concepto de especie en los últimos 2300 años, y sus muchos altibajos de la biología ya desde Aristóteles. Se discute el papel que el concepto moderno de especies biológicas juega en la biología evolutiva, y enfatiza su importancia en la enseñanza de la biología. ESP
