Madness (about) seeing: dalla costruzione sociale del visuale alla costruzione visuale del sociale
2017
La cultura che siamo soliti definire come “occidentale” possiede nell’oculocentrismo, come altre, più di altre, uno dei suoi tratti maggiormente distintivi. Individuato, tra gli altri, il senso della vista come canale privilegiato per relazionarsi con il mondo, l’uomo occidentale ha dato origine ad un’operazione di trasfigurazione del reale in termini visivi che lo ha condotto, in tempi recenti, ad identificarsi con gli oggetti che tale processo ha messo al mondo; da più parti, infatti, ci viene detto che viviamo nella (non meglio definita) “società delle immagini”. Subito dopo aver analizzato il luogo e il tempo in cui la preferenza per il vedere ha piantato le proprie solidissime e rizoma…
CRITERIA FOR SUSTAINABILITY OF OLD-AGE PENSION SYSTEM BASED ON THE NDC PRINCIPLES
2015
The topicality of the research subject. The foundations of the old-age pension scheme based on notional accounts, also referred to as the “notional defined contribution” or “non-financial defined contribution” (NDC) old-age pension scheme, were laid in Sweden in 1994, when the prevailing view was that a sustainable defined-contribution PAYG old-age pension scheme is impossible. Since then, the NDC system modifications have been implemented in several countries; since 2000, this scheme is also part of the Latvian pension system and works significantly better than the other part of the pension system - the funded pension scheme. However, the sustainability of NDC scheme is still being questio…
Design and modelling a of bimodal camera system
2021
In computer vision, researchers face a challenging concern due to the limited field of view (FoV) when using standard cameras in capturing scenes. This problem of narrow FoV often encountered within applications that involve tasks which are related to the robot vision. Many authors have attempted, in different approaches, to solve this issue by fusing two cameras. However, they failed to improve the registration and fusing errors, where the obtained results still limited and not accurate enough. To deal with this limitation and decrease these errors, we propose a new method of camera calibration based on Interior-Point Optimisation (IPO) algorithm using transformation matrix estimation. Thi…
The BaBar detector: Upgrades, operation and performance
2013
The BABAR detector operated successfully at the PEP-Il asymmetric e(+) e(-) collider at the SLAC National Accelerator Laboratory from 1999 to 2008. This report covers upgrades, operation, and performance of the collider and the detector systems, as well as the trigger, online and offline computing, and aspects of event reconstruction since the beginning of data taking.
Ontological levels in the knowledge management field
2013
The purpose of this study is to examine the relationship between knowledge and reality in the field of management, highlighting the importance of ontological support in the formation of knowledge. The empirical study establishes those ontological levels in large Spanish firms. The article underlines the importance of ontological support and of practice carried out in forming knowledge, and reviews different approaches. The empirical study identifies, via an exploratory factor analysis, the ontological supports of knowledge in large Spanish firms, going on to apply a confirmatory factor analysis that shows the fit of the factors obtained from the sample. The discussion carried out suggests t…
Research Directions in the Study of Gaming-Related Escapism: a Commentary to Melodia, Canale, and Griffiths (2020)
2021
AbstractEscapism motivations and related processes (e.g., avoidance, dissociation, relaxation, and emotion dysregulation) have been identified as risk factors for problematic gaming. However, the escapism construct has often been poorly conceptualized and operationalized in assessment instruments. In their systematic review, Melodia et al. (2020) proposed that conceptualizing escapism as an avoidant coping strategy could provide a sound basis for further study of problematic gaming. In this commentary, we critically examine some terminological and conceptual issues in relation to escapism to guide future research.
Analysis of the road traffic management system in the neural network development perspective
2019
The research goal of the paper is to present the issues connected with road traffic management systems and to illustrate a management system that uses Intelligent Transportation Systems and neural networks. The use of Intelligent Transportation Systems (ITS) is a method of improving the conditions of communications, making it independent from the development of communications infrastructure. The attributes of neural networks are focused on solving the problems of optimisation, which involve the development of optimal strategies for traffic management. The proposed road traffic management system that uses ITS and neural networks can be applied in prediction of the conditions of communication…
Empirical BAC factors method application to two real case studies in South Italy
2021
Abstract The application of Building Automation and Control (BAC) systems has many advantages. One of these is the reduction of the end-user electricity consumption and, if applied to lighting systems, the achievement of well-acknowledged benefits from daylight, such as productivity, health, visual comfort and well-being. Concerning the first aspect, the international Standard EN 15232 proposes the so-called BAC Factors (BF) method to assess the impact of BAC systems on the final energy consumption. The method provides a simplified estimation of the energy savings due to automation in buildings and questions arise on its applicability in some situations. For this reason, the authors have ca…
Paper vs. Pixel: Can We Use a Pen-and-Paper Method to Measure Athletes' Implicit Doping Attitude?
2017
Doping attitude is an individual’s subjective evaluation (e.g., good or bad, useful or useless) toward the use of prohibited performance-enhancing substances or methods in sports. Research on doping attitude has traditionally relied on self-report questionnaire methods to measure the construct (Ntoumanis et al., 2014; Chan et al., 2015). However, as doping in sport is illegal (World AntiDoping Agency, 2015) and perceived as socially unacceptable, athletes who hold positive attitudes toward doping are less likely to reveal them to others. As a result explicit measures of doping attitude are susceptible to potential bias as athletes may respond in a socially desirable fashion (Petróczi and Ai…
A fast algorithm for muon track reconstruction and its application to the ANTARES neutrino telescope.
2011
An algorithm is presented, that provides a fast and robust reconstruction of neutrino induced upward-going muons and a discrimination of these events from downward-going atmospheric muon background in data collected by the ANTARES neutrino telescope. The algorithm consists of a hit merging and hit selection procedure followed by fitting steps for a track hypothesis and a point-like light source. It is particularly well-suited for real time applications such as online monitoring and fast triggering of optical follow-up observations for multi-messenger studies. The performance of the algorithm is evaluated with Monte Carlo simulations and various distributions are compared with that obtained …
