Learning and using English and Swedish beyond the classroom : activity systems of six upper secondary school students
2012
Tämän tutkimuksen tarkoituksena oli katsoa englannin ja ruotsin oppimista koulun ulkopuolella toiminnan teorian ja erityisesti Engeströmin (1987, 1999) toimintajärjestelmämallin näkökulmasta, josta aihetta ei ole aiemmin lähestytty. Tutkimus vastaa seuraaviin kysymyksiin: 1) Ovatko abiturientit enemmän kielenkäyttäjiä vai -oppijoita englannissa ja ruotsissa koulun ulkopuolella? 2) Millaisia eroja ja yhtäläisyyksiä heidän toiminnassaan on englannissa ja ruotsissa? 3) Mitkä tekijät selittävät aktiivisuutta ja passiivisuutta? Tutkimus on toteutettu tapaustutkimuksena. Tutkimusaineistona on kuusi puolistrukturoitua haastattelua. Haastateltavat ovat 18-vuotiaita lukion kolmannen vuosikurssin opi…
A Psychoacoustic Model of Harmonic Cadences - A Preliminary Report
2009
This report presents a psychoacoustically derived computational model of the perceived distance between any two major or minor triads, the degree of activity created by any given pair of triads, and the cadential effectiveness of three-triad progressions. It also provides statistical analyses of the ratings given by thirty-five participants for the ?similarity? and ?fit? of triads in a pair, and the ?cadential effectiveness? of three-triad progressions. Multiple regressions show that the model provides highly significant predictions of the experimentally obtained ratings. Finally, it is argued that because the model is based upon psychoacoustic axioms, it is likely the regression equations …

Siracusa e la Sicilia nel III secolo a.C.: problemi conoscitivi e proposte di lettura dei fenomeni urbanistici e architettonici
2017
L’evoluzione sotto il profilo urbanistico e architettonico delle città di Sicilia nel III secolo a.C. può essere compresa solo a partire da un esame delle evidenze di Siracusa, la maggiore città dell’Occidente greco-ellenistico e capitale di un regno che sotto Agatocle e soprattutto sotto Ierone II vede un prodigioso sviluppo non solo per l’estensione dell’area urbana, ma soprattutto per la riconfigurazione dello spazio cittadino in forme innovative, destinate a influenzare in maniera decisiva anche le città minori del regno e dell’Oriente dell’isola, e successivamente anche dei comprensori centro-occidentali e settentrionali. L’aspetto più importante e programmatico nella rimodulazione del…
Service Climate and Display of Employees’ Positive Emotions: The Mediating Role of Burnout and Engagement in Services
2011
This article aims to test a model linking service climate to the frequency of expression of positive emotions by frontline employees. We propose that burnout and engagement at work mediate the relationship between service climate and the expression of positive emotions. Service climate impacts negatively on burnout and positively on engagement; in turn, burnout and engagement are significantly related to the frequency of expression of positive emotions. This model was tested both at the individual and work-unit levels. In addition, it was compared with a direct model that proposes an additional direct link from service climate to frontline employees’ positive emotions. Models were tested th…
Smart Wireless Sensor Networks and Biometric Authentication for Real Time Traffic Light Junctions Management
2013
The main challenge of intelligent transportation systems (ITS) is to deal with ‘real-time’ information to improve vehicular traffic management. Road data can be processed and used for dynamic traffic light management in order to reduce waiting times in queues. This paper proposes an innovative distributed architecture based on a wireless sensor network (WSN) with a network coordinator providing remote and ubiquitous authentication module for managing unexpected events. The architecture is completed by a dynamic module for street priority management depending on traffic rate. Many experimental trials have been carried out considering three different levels of traffic intensity to prove the e…
Estimating traffic operations at multi-lane roundabouts: A case study
2014
This paper addresses traffic modeling issues at urban multi-lane roundabouts where, despite circulating vehicles have priority, negotiation of the right-of-way can occur between antagonist traffic flows, as a result of minor drivers’ failing to obey the nominal operating rule (stop or yield control). Existing models for the estimation of operational performances have the shortcoming of not representing the interdependencies between entering and circulating vehicles at multi-lane roundabouts. An analytical capacity model derived from field observations was developed for this kind of intersections in a previous study. The complexity of the model lies in the difficulty of observing the behavio…
Dealing with the right of way in advanced traffic simulation. A characterization of drivers' behaviours in a multi-agent approach
2017
International audience; With the emergence of ADAS and autonomous vehicle, the need of simulation software to test advanced systems and models is unavoidable. The objective of this work is to characterize, in a multi-agent approach, the traffic vehicles behaviours, and to model them in a versatile traffic simulator, serving as a testing tool for integration in the traffic module of the SCANeR Studio T M simulation software. The algorithm will bring more natural interactions between vehicles in simulation and allow the emergence of new relevant situations for autonomous vehicles, observable in real, such as collision risk situations or even accidents, which have for now to be scripted in sce…

2020
Il capitolo descrive un modello pilota di corso di formazione per "Esperti in violenza di prossimità" basato su un approccio sistematico in grado di implementare il know-how e le competenze specifiche necessarie per affrontare la violenza di genere e di prossimità da parte dei professionisti che lavorano nei vari centri di accoglienza. The chapter describes a pilot model of training course fo "Experts in proxility violence" based on a systematic approach capable of implementing the know-how and the specific skills required to address gender and proximity violence by the professionals working in the various reception centers.
Diversification in evolutionary arenas - assessment and synthesis
2019
Abstract Understanding how and why rates of evolutionary diversification vary is a central issue in evolutionary biology and ecology. The concept of adaptive radiation has attracted much interest, but is metaphorical and verbal in nature, making it difficult to quantitatively compare different evolutionary lineages or geographic regions. In addition, the causes of evolutionary stasis are relatively neglected. Here we review the central concepts in the evolutionary diversification literature and bring these together by proposing a general framework for estimating rates of diversification and quantifying their underlying dynamics, which can be applied across clades and regions and across spat…
