Secure random number generation in wireless sensor networks

2011

The increasing adoption of wireless sensor networks as a flexible and inexpensive tool for the most diverseapplications, ranging from environmental monitoring to home automation, has raised more and more atten-tion to the issues related to the design of specifically customized security mechanisms. The scarcity ofcomputational, storage, and bandwidth resources cannot definitely be disregarded in such context, and thismakes the implementation of security algorithms particularly challenging. This paper proposes a securityframework for the generation of true random numbers, which are paramount as the core building blockfor many security algorithms; the intrinsic nature of wireless sensor nodes …

Relaciones de género entre los Wayuu. Estado de la investigación y nuevos campos de análisis

2006

L'articolo esamina le relazioni di genere tra i Wayuu della Colombia. Vengono esaminati i rapporti tra genere, discendenza matrilineare e gerarchie di status basate sulla ricchezza. La posizione delle donne è trattata sia in riferimento all'organizzazione sociale, sia nelle guerre interne, sia a livello simbolico, tanto nella mitologia che nei rituali. Il ruolo di interfaccia tra interno ed esterno del sè collettivo giocato dalle donne si esprime tra i Wayuu in particolare nel loro ruolo preponderante come sciamene che in quello di rappresentanti del gruppo nelle negoziazioni con le istituzioni non indigene

La governance delle aree rurali: l’esperienza del GAL «Elimos»

2018

Il presente lavoro intende inserirsi in seno al dibattito scienti co sul riordino territoriale italiano. In particolare, ci si concentra sull’esperienza dei GAL (Gruppi di Azione Locale) che, seguendo l’approccio LEADER, sono chiamati a gestire e indirizzare lo sviluppo locale delle aree rurali. Questo contributo affronta, con approccio geogra co, le principali prospettive di sviluppo di un’area interna della Sicilia, individuata dal GAL Elimos, del quale si analizzerà la strategia di sviluppo locale e i risultati conseguenti. This paper aims to fit into the scientific debate on Italian territorial re-organization. This paper focuses on the case of GAL (Local Action Group): a bottom up gove…

LA QUESTIONE DELLA VALUTAZIONE DELLE PERFORMANCE DI SVILUPPO LOCALE NEI GAL. UN APPROCCIO GEOGRAFICO

2019

This paper aims to advance a critical review of a LAG’s Local Development Strategy. This paper is methodologically based on the geographical qualitative approach; moving from the debate about the local development, the contribution tackles a case study and proposes an initial reflection on the possible approaches to the evaluation of the performance of LAG policies in the territory.

Psychological Well-Being among Adolescents and Youth.

2022

Today, the construct of well‐being has assumed increasing importance in various areas of psychology by identifying several factors of personal order (personality dispositions, self‐esteem, perception of control), interpersonal (social support), and socioeconomic (income, level of education), variables that can influence well‐being to a greater or lesser extent. Research on the construct has been derived from two influential approaches or perspectives: the hedonic approach, which focuses on pleasure and happiness and on the achievement of well-being through the satisfaction of one’s desires, and the eudaimonic approach, according to which well-being is obtained by fulfilling one’s potential …

Sportspersonship In Martial Arts

2017

Studies on psychological outcomes related to individual differences have increased showing contradictory results, especially in martial arts. The difficulty to provide conclusive evidence for the psychological outcomes of martial arts practice and to determine if and to what extent martial arts trainings explain the above mentioned effects needs a more in-depth analysis of those dispositional aspects which can impact adaptive behaviors in terms of sportspersonship. Since no studies on sportspersonship and goal orientations has been carried out in the specific context of martial arts, the current research aimed at examining the role of goal orientations and trait aggressiveness as predictors…

Scritti in onore di Pellegrino Capaldo

2014

La qualità dei servizi è stata riconosciuta come un rilevante aspetto caratterizzante la performance dell’azienda pubblica, analogamente alla capacità di operare secondo criteri di efficienza e nel rispetto dei vincoli di bilancio. Sebbene sia possibile riscontrare alcuni significativi casi di adozione di politiche di customer satisfaction nelle amministrazioni pubbliche italiane, a tutt’oggi il tema presenta significative criticità, specialmente in ordine agli aspetti metodologici e agli strumenti operativi che consentano di integrare dette politiche nel sistema di programmazione e controllo delle aziende che erogano tali servizi. Il presente lavoro adotta una diversa prospettiva di analis…

Settore SECS-P/07 - Economia AziendaleQuality in delivering public services has been recognised as a major issue challenging performance in the public sector as well as the ability to operate effectively and within budget constraints. Empirical findings shown by the literature demonstrate that concrete efforts have been produced towards the evaluation and improvement of satisfaction levels of citizens and other Public Administration’s ‘customers’. However still today this issue portrays many unresolved criticalities particularly concerning the methodological approaches and operative tools to adopt in order to integrate ‘customer satisfaction’ programs with the wider organisational control system in each public administration. This paper adopts a non-conventional view of the ‘customer satisfaction’ concept. This is currently meant as a matter of social reporting or even statistical analysis based on the users’ perceptions on the level of provided services by a given (front office) unit in the public sector. Here an inter-institutional perspective is adopted with a view to map the overall value chain leading to the final product delivered to citizens or the community. Inside this chain tracking the underlying administrative products delivered by back-office units to their ‘internal clients’ in the public administration is recommended as a fundamental step to understand how to improve performance in satisfying citizens’ needs. This should also require a proper link between the administrative units’ goals and performance measures to the desired efficiency and effectiveness of processes leading to the attainment of administrative products providing the basis of the final services delivered to the private sector. Based on first empirical findings from field analysis in the Italian context the paper aims to outline an approach which could assist both politicians and managers to better assess and improve performance according to a customer satisfaction perspective.
