A dynamic model to value the economic impact and the economic sustainability of tourism in a resort area
2007
The systemic approach in studying tourism is firmly accepted in literature because of the complexity of the topic both from the supply side (the heterogeneity of goods and services making the tourism product) and the demand side (not every operator in the tourism network chain has a direct contact with tourists). To face this complexity the Input-Output analysis, theorized by Wassily Leontief, is widely used in empirical studies of tourism. Yet, in spite of such a diffusion and importance in tourism literature, the Input-Output models have several limits. In order to overcome some of these limits, the static Input-Output analysis is translated into a dynamic one by making use of System Dyna…
Job shop scheduling by a parallel approach
1993
The paper deals with a parallel approach to job shop scheduling by a branch and bound methodology using the lower bound proposed by Ashour and Hiremath. The optimal solution is achieved by an iterative-reductive strategy. At each iteration the algorithm investigates the conflict intervals and it selects a subset of the possible solutions. The makespan value, achieved by the parallel processes, gives the upper limit for the admissible lower bound of the intermediate solutions. Furthermore the best makespan reached by each iteration is reused as a filter to reduce the complexity of the next iteration. The computation is speeded up by a parallel implementation, giving the possibility of distri…
Recensione di La Dichiarazione universale dei diritti umani. Storia, tradizioni, sviluppi contemporanei
2022
Il volume a cura di Raffaella Gherardi "Dichiarazione universale dei diritti umani. Storia, tradizioni, sviluppi contemporanei" è suddiviso in tre parti precedute da un saggio introduttivo e concluse con un’appendice in cui è riportata la Dichiarazione approvata e proclamata il 10 dicembre 1948, mettendosene in rilievo nei diversi contributi il valore storico e politico, per l’incidenza che da allora esercita sul piano dei diritti umani e della loro configurazione e promozione universale. Le tre parti del volume approfondiscono a più voci: l’evoluzione dei diritti umani dalla modernità ai nostri giorni; la visione contemporanea oltre la tradizione occidentale; lo sviluppo odierno nella pros…
The Countryside in Sicily under the Roman Empire: Archaeological Survey and Methodological Approach, Settlements and Resources
2019
Si illustra lo stato delle attuali conoscenze archeologiche relative al paesaggio rurale di età romana della Sicilia, attraverso i risultati delle prospezioni archeologiche e di analoghe ricerche effettuate a partire dagli anni '80 del secolo scorso. In alcuni territori (come Himera, Gela, Agrigento, Alesa, e in altre aree interne) queste ricerche hanno prodotto informazioni nuove che aiutano a comprendere le differenti dinamiche storiche che caratterizzano varie aree dell'isola. The object of this report is to describe the current knowledge about the Roman landscape of Sicily, and the results connected to the archaeological surveys and other similar researches carried out from the eighties…
Inquiry-based environments for bio-signal processing training in engineering education
2021
Active student engagement, teaching via experience in real-life settings and learning by doing, are pedagogical strategies appropriate to improve student-reasoning skills. By building models, performing investigations, examining and explaining experimental results, using theoretical and computational thinking, constructing representations, undergraduates can acquire a deeper understanding of fundamental disciplinary concepts while reinforcing transversal abilities. In this framework, Engineering courses should be designed with the final objective to develop practical skills, focusing on hands-on activities. This contribution presents two different inquiry-based learning environments recent…
Surgical Highways to the Craniovertebral Junction: Is It Time for a Reappraisal?
2019
Background: The craniovertebral junction (CVJ) can be affected by a variety of congenital or acquired anomalies. Because of its complexity, a careful evaluation of bones and ligamentous structures in all three planes is required. This can be achieved by studying the CVJ in terms of several anatomical and radiological lines that have been visualized to facilitate understanding of its surgical anatomy. In this study we aimed to review the state-of-the art craniometric CVJ lines and approaches. Methods: In December 2016 a PubMed search was performed, including the search terms ‘CVJ surgical approach/line’, ‘cervical approach’, ‘craniometric measurement’, ‘CVJ anatomy’ and ‘ventral/dorsal/far-l…
Religioznyj stil’ v slavânckoj teolingvistike
2020
At the turn of the 20th and 21st centuries, the main threads of research in Slavic theolinguistics were emerged, one of which was the study of religious style. Linguists in Poland, Russia, Serbia, Slovakia, the Czech Republic and Ukraine pay special attention to this issue. This article provides a brief overview of the given problem. These studies have both common points and differences. This is explained not only by the various confessions associated with specific languages, but also by the linguistic traditions that have developed in each of these countries.
A distributed-memory MPI parallelization scheme for multi-domain incompressible SPH
2022
A parallel scheme for a multi-domain truly incompressible smoothed particle hydrodynamics (SPH) approach is presented. The proposed method is developed for distributed-memory architectures through the Message Passing Interface (MPI) paradigm as communication between partitions. The proposal aims to overcome one of the main drawbacks of the SPH method, which is the high computational cost with respect to mesh-based methods, by coupling a multi-resolution approach with parallel computing techniques. The multi-domain approach aims to employ different resolutions by subdividing the computational domain into non-overlapping blocks separated by block interfaces. The particles belonging to differe…
Personal goals and well-being: How do young people navigate their lives?
2010
This chapter examines development through different life transitions, such as educational transitions and transition to parenthood during adolescence to adulthood in the context of the life-span model of personal goals. According to the life-span model of motivation, four key mechanisms—channeling, choice, co-regulation, and compensation—play a key role in how young people navigate their life. The aim is to describe how the conceptualized key factors are helpful in understanding the changes from adolescence to emerging adulthood and later in the life course and related well-being. © Wiley Periodicals, Inc.
Profiles of school motivation and emotional well-being among adolescents : Associations with math and reading performance
2018
This study examines profiles of school motivation and emotional well-being and their links to academic skills (reading and math) among adolescents (N = 1629) at the end of comprehensive school (age 15–16). Using a person-centered approach (latent profile analysis), five distinct profile groups were identified. Three of the identified groups had a flat profile in motivation and well-being but at different levels. The first group manifested high motivation and well-being (n = 178, 11%); the second group was average in both (n = 1107, 68%); and the third had low motivation and well-being (n = 121, 7%). Two groups had mixed profiles; one group manifested only low motivation (n = 140, 9%) and th…
