Correlates of identity configurations: Three studies with adolescent and emerging adult cohorts.
No full textAdolescence and emerging adulthood are two core developmental periods in which individuals can develop a meaningful identity across domains. However, there is a lack of studies exploring correlates of different identity configurations. The purpose of this article was to fill this gap in examining correlates of configurations characterized by identity stability or instability in both ideological and relational domains or identity stability in one domain and instability in the other domain. Three studies were presented. In the first study, we investigated links between identity configurations and internalizing problem behaviors in early and middle adolescents (N = 1,891; M age = 14; 55% female); in the second study, we focused on associations between identity configurations and identity functions in late adolescents and early emerging adults (N = 1,085; M age = 19; 63% female); in the third study, we investigated relationships between identity configurations, sense of coherence, and basic psychological need satisfaction in emerging adults (N = 489; M age = 21; 71% female). Overall, findings highlighted that participants experiencing a condition of identity stability in both domains reported a better profile than their peers displaying a condition of instability in both realms. Further, individuals with identity stability only in one domain reported intermediate scores and the effect provided by each domain varied according to the correlate examined and the age group taken into account. Implications of these findings are discussed
Performance evaluation of LoRa networks in a smart city scenario
No full textLow-Power Wide Area Networks (LPWANs) are continuously gaining momentum as fundamental enablers of the Internet of Things (IoT) paradigm. These networks provide longrange coverage to end nodes, exploiting license-free frequency bands. The focus of this work is on one of the most prominent LPWAN technologies: LoRaTM. We implemented a new ns-3 module to study the performance of a LoRa-based IoT network in a typical urban scenario. Simulation results show that a LoRa network can scale well, achieving packet success rates above 95% in presence of a number of end devices in the order of 10 4

No full textLa percezione sociale della devianza giovanile in Italia e Russia: un confronto cross-culturale
No full textIl lavoro di ricerca che viene presentato si svolge nell’ambito di una collaborazione tra l’Università Cattolica di Milano e l’Università di Novosibirsk. È stata condotta una ricerca cross-culturale su due campioni di adolescenti in Italia e in Russia sul tema della devianza minorile e della reazione sociale e giudiziaria a comportamenti e reati di diversa gravità. Sono stati somministrati questionari ad adolescenti, genitori e insegnanti sia in Italia che in Russia. Vengono presentati i risultati dei due campioni nel confronto cross-culturale
A Thorough Study of LoRaWAN Performance under Different Parameter Settings
No full textLoRaWAN is an emerging low-power wide-area network (LPWAN) technology, which is gaining momentum thanks to its flexibility and ease of deployment. Conversely to other LPWAN solutions, LoRaWAN indeed permits the configuration of several network parameters that affect different network performance indexes, such as energy efficiency, fairness, and capacity, in principle making it possible to adapt the network behavior to the specific requirements of the application scenario. Unfortunately, the complex and sometimes elusive interactions among the different network components make it rather difficult to predict the actual effect of a certain parameters setting, so that flexibility can turn into a stumbling block if not deeply understood. In this article, we shed light on such complex interactions for a single-gateway (GW) system by analyzing the effect of some built-in features and configurations, including the GW's limitations in terms of duty cycle and the number of parallel reception paths, the number of allowed retransmissions for confirmed traffic, and the preconfigured data rate used in downlink transmissions. The simulation-based analysis reveals various tradeoffs and highlights some inefficiencies in the design of the LoRaWAN standard. Furthermore, we show how significant performance gains can be obtained by wisely setting the system parameters, possibly in combination with some novel network management policies (e.g., enabling selective prioritization of downlink transmissions at the GW)
Collsional timing of asteroids space weathering: A First approach
No full textThe space weathering, i.e. the evolution of surface properties over time, due to the exposure to external factors, has been shown to affect the optical properties of the asteroids, usually causing reddening (an effect which is measured in terms of the spectral slope in the visible and near infrared range) and darkening over time. However, some problems remain open. In particular, the timescale for reddening, which we estimate from laboratory experiments, is shorter—maybe, by two or even more orders of magnitude—than the typical asteroidal ages. Thus we should expect a complete saturation of the reddening effects for most of the objects, which does not happen, instead of a general significant dependence of the slope on the age, as indeed we find. In this paper we discuss, with the aid of a simplified model, how the collisions may affect the timing of the reddening process. We show that the collisions might halt the reddening, unless a significant reaccumulation of the fragments created in the cratering collisions takes place. In this case the timing for the complete reddening is driven by the collisional events, thus providing a rationale for the observed slope-age and slope-exposure relations
