Dance moves reflect current affective state illustrative of approach–avoidance motivation.

Il legame di attaccamento ai genitori e ai pari come predittore dell’autostima e dell’ego-resiliency.
2017
The aim of this study was to analyse the relationship between the quality of attachment relationships with parents and peers on the one hand, and ego-resiliency and self- esteem on the other hand. The present research was conducted with a group of 218 students (male = 101) aged from 11 to 19 years (M = 14.43, DS = 2.60). The results emphasize that (a) self-esteem is positively associated only with security of attachment to the mother, (b) ego-resil- iency is positively associated with security of attachment both to mother and peers, and (c) boys seem to have higher levels of self-esteem and ego-resiliency than girls.
An Energy Blockchain, a Use Case on Tendermint
2018
The recent advances in distributed energy systems require new models for exchanging energy among prosumers in microgrids. The blockchain technology promises to solve the digital issues related to distributed systems without a trusted authority and to allow quick and secure energy transactions, which are verified and cryptographically protected. Transactions are approved and subsequently recorded on all the machines participating in the blockchain. This work demonstrates how users, which are nodes of the energy and digital networks, exchange energy supported by a customized blockchain based on Tendermint. We focus on the procedures for generating blocks and defining data structures for stori…
Aggregation and remuneration in Demand-Response with a blockchain-based framework
2020
This paper describes the possibility to use the blockchain technology for load and generation aggregation in a new distributed Demand Response (DR) service and customers remuneration system. The blockchain technology and the use of smart contracts for DR allow the creation of a distributed system in which customers can communicate directly, in a transparent, secure and traceable way, with the grid operator to provide their flexibility. In this paper, the DR problem formulation takes into account several aspects, which are periodically executed. First, the blockchain records customers’ energy consumption or production, then, the smart contract starts calculating the baseline and the potentia…
Improving Chord Lookup Protocol for P2PSIP-Based Communication Systems
2009
Chord has been suggested as mandatory overlay technology in the future P2PSIP-based communication systems. Chord allows for the available peer/resource lookup in no more than hops, where N is the total number of the peers in the overlay network. However, as a protocol originally designed for background downloading applications, Chord has a few drawbacks when supporting P2PSIP real-time communication systems. These drawbacks are related to ID assignment, the relation between ID and physical location, the routing styles and lack of cache, etc. In this paper, we investigate several approaches that can improve the efficiency of the peer/resource lookup algorithm. After that, we simulate two sys…
Autonomy, Heterogeneity and Trust in Mobile P2P environments
2007
Mobile P2P environments are emerging as a result of rapid expansion of portable terminals that are able to establish direct wireless communication links among themselves. These kinds of terminals are under the control of persons and allowing interactions between their terminals is subject to trust between the individuals and their desire to preserve various aspects of autonomy against each other. In this paper we relate the concepts of node autonomy, heterogeneity and trust with each other, defining also numeric measures for them. We also investigate what kind of interactions (such as transactions, file exchanges) are possible at certain heterogeneity, autonomy and trust level between the t…
A Case Study of Open Source Software Development in Proteomic Area: The LIMS ePims
2008
The objective of this paper is to provide an illustrative feedback on development of Open Source software among several partners. We describe the first stage of the design of a specific software package, namely a customized Laboratory Information Management System (LIMS) for biology applications. This software package is structured in several modules which are reusable and can be customized for other applications. In this paper, we address the problem of multi-licensing for the same software tools due to the participation of several partners, the reuse of code source, and the subsequent distribution of this produced software.
Consumo di cannabis, gruppo dei pari e strutturazione del Sè in adolescenza
2011
La conquista di un nuovo senso di identità e la rappresentazione di essa come frutto dell’integrazione delle trasformazioni psico-fisiche che travolgono il proprio corpo, è un percorso lento e di certo non privo di tensioni, che si snoda nel corso di tutta l’adolescenza. La costruzione identitaria adolescenziale non è però solo un processo intrapsichico, essa si articola anche attraverso il confronto che il giovane ha all’interno dello spazio sociale che lo circonda, mediante il rapporto con i pari ed i nuovi ruoli sociali progressivamente ricoperti. In questa fase di vita, il gruppo dei pari assume nuove valenze e funzioni specifiche, fornendo un modello di confronto e identificazione con …
Factores facilitadores y barreras en la transición a la ciencia abierta: perspectiva de los agentes del sistema científico español
2022
This paper presents the results of a research study whose objective was to identify the facilitating factors and barriers that, in the opinion of representatives of the Spanish scientific community, impact the implementation of the new open science model in four areas: open access, open research data, research assessment and open peer review. A qualitative study was designed in which information was obtained through interviews with researchers, editors of scientific journals, representatives of assessment agencies and vice-chancellors, and through a focus group of librarians with expertise in aspects of open science. The enabling factors and barriers identified were related to the researche…
Cyberbullismo e videopeer education
2014
Lo scopo di questo articolo – attraverso un processo di ricerca-azione che coinvolge un cam-pione di 243 soggetti pre-adolescenti ed adolescenti – è quello di sottolineare come il mezzo in-formatico può essere causa di aggressioni, molestie, offese; ma allo stesso tempo, utilizzato come fonte di nuove strategie comunicative, di interazione gruppale e di intervento educativo in comunità virtuali. Il cyberbullismo si materializza nella vita delle vittime in ogni momento della giornata e at-traverso diverse realtà (video, foto, mail, chatroom, sms, chiamate telefoniche, ecc). Uno dei metodi di prevenzione, che guarda alle dinamiche di gruppo ed alle tecnologie mediali come fonte educative, è l…
