In people with intellectual disabilities, an enriched environment can stimulate the acquisition of motor skills and could partially repair neuronal impairment thanks to exploration and motor activity. A deficit in environmental and motor stimulation leads to low scores in intelligence tests and can cause serious motor skill problems. Although studies in humans do not give much evidence for explaining basic mechanisms of intellectual disability and for highlighting improvements due to enriched environmental stimulation, animal models have been valuable in the investigation of these conditions. Here, we discuss the role of environmental enrichment in four intellectual disabilities: Foetal Alcohol Spectrum Disorder (FASD), Down, Rett, and Fragile X syndromes. © 2017 Informa UK Limited, trading as Taylor & Francis Group

The centrifugal track is a basin-shaped track characterised by a platform with a parabolic section. The model analysed in this technical note is characterized by five circular lanes with an increasing radius (from 2.59 to 3.37 m) and inclination (from 34° to 60°). The athlete has to run on a selected lane while changing direction at every support phase to maintain a circular trajectory. This gives rise to a centripetal acceleration of the centre of mass that, added to gravity, results in an overweight of the runner. Each lane is associated with a corresponding running speed that allows the athlete to run perpendicular to the contact surface. The overweight associated with each lane ranges from 1.2 to 2 times the subject’s body weight and it is achieved at running speeds ranging from 4.6 m/s to 8.8 m/s, respectively. In this technical note, the dynamics of the foot contact phase while running on the centrifugal track is described as a theoretical foundation for presenting this track as a sprint-specific strength training tool. © 2017 International Sports Engineering Association

Service systems’ capabilities to generate (positive or negative) externalities and their impact at the societal level has remained under-investigated so far. This study addresses this gap and explores how an innovative organizational architecture based on (i) a network of competent actors, (ii) an (ICT-enabled) platform serving as a network commons and (iii) a shared institutional logic and worldview enables the emergence and evolution of a service ecosystem with strong positive externalities. It was conducted an in-depth longitudinal study (2013–2016) on an ICT-enabled community of IT professionals, aimed to provide unemployed professionals with employment opportunities while also providing small and micro enterprises and non-profit organizations with affordable, high-level IT services. The case-study shows that the presence of non-profit organizations in the service ecosystem strongly influences the service ecosystem’s institutional logic and worldview and facilitates sustainability-oriented self-organizing throughout the ecosystem. © Springer International Publishing AG 2017.

During the past two decades, there has been increasing interest in understanding and characterizing the role of inflammation in major depressive disorder (MDD). Indeed, several are the evidences linking alterations in the inflammatory system to Major Depression, including the presence of elevated levels of pro-inflammatory cytokines, together with other mediators of inflammation. However, it is still not clear whether inflammation represents a cause or whether other factors related to depression result in these immunological effects. Regardless, exposure to early life stressful events, which represent a vulnerability factor for the development of psychiatric disorders, act through the modulation of inflammatory responses, but also of neuroplastic mechanisms over the entire life span. Indeed, early life stressful events can cause, possibly through epigenetic changes that persist over time, up to adulthood. Such alterations may concur to increase the vulnerability to develop psychopathologies. In this review we will discuss the role of inflammation and neuronal plasticity as relevant processes underlying depression development. Moreover, we will discuss the role of epigenetics in inducing alterations in inflammation-immune systems as well as dysfunction in neuronal plasticity, thus contributing to the long-lasting negative effects of stressful life events early in life and the consequent enhanced risk for depression. Finally we will provide an overview on the potential role of inflammatory system to aid diagnosis, predict treatment response, enhance treatment matching, and prevent the onset or relapse of Major Depression. © 2015 Cattaneo, Macchi, Plazzotta, Veronica, Bocchio-Chiavetto, Riva and Pariante.

The study of the organizational impact of information technology services on the value generation process in organizations has a story that spans over several decades. In this stream of research, that goes under the name of IT value, scholars debated over years on the potential existence of a positive link between the presence of IT services and the organizational performance. The field of IT value is ample and continuous. Considering these aspects this paper contributes to the literature by proposing a quantitative analysis of the IT value literature. Our study complements existing studies on the value of IT services, which followed qualitative approaches, focusing on the summarization and systematization of existing literature. This paper presents the results of a longitudinal bibliometric study of the IT value literature based on 435 papers published from 1990. Our analysis shows a growing trend of publications and citations, the existence of a common theoretical foundation for the research stream identified by the most influential and co-cited sources. Our analysis identified the existence of three core research areas inside which most of the IT value discourse is developed. We concluded our research formulating some considerations regarding future IT service value investigations. © Springer International Publishing AG 2017.

Several problems in transportation and communication networks lead to the notion of Wardrop equilibrium. There exists a large number of algorithms to find Wardrop equilibria, both centralized and distributed. This paper presents a distributed control algorithm, which converges to a Wardrop equilibrium, derived from the algorithm presented in Fischer and Vöcking (2009). The innovation lies in the fact that convergence results are obtained considering that communications occur over time-varying communication graphs, with mild assumptions on the graph connectivity in time (uniform connectivity). © 2017 Elsevier Ltd

This review investigates the contribution of John Biggs in playing an important role within learning research and educational system quality. Schools and Universities have gradually structured their policies on the bases of their students’ perceptions, satisfaction, and needs. The interest in the measurement of student’s study strategies and perceptions is the result of the needs for educational institutions to demonstrate their effectiveness in teaching. Biggs’s model conceptualizes the learning process as an interactive system of three sets of variable: the learning environment and student characteristics, students’ approach to learning, and learning outcomes. By exploring findings from educational studies, the review seeks to examine the evolution of Biggs’s learning model and his contribution to understand individual, interpersonal and contextual factors that determine effectiveness of learning. © 2017, Italian e-Learning Association.

Recycling of waste materials is actually one of the main targets in civil engineering, because of economic and environmental features. To this aim, the field of road engineering offers many technical solutions, including the use of recycled materials from construction and demolition of civil works (C&D) in pavement layers. These materials have been investigated to be used as aggregate in asphalt concrete base layers for flexible road pavements. Different percentages (0, 15, 30 and 50 %) of C&D materials were used in order to determine the most suitable solution. The scope was to evaluate both static and dynamic mechanical properties of the mixtures. In particular, a servo-hydraulic control static press was used to run indirect tensile tests and a Nottingham Asphalt Tester was used to determine indirect tensile stiffness modulus and fatigue strength. Specimens were manufactured by mixing the aggregate with 5% of bitumen and compacted with a shear gyratory compactor to a fixed height, in order to have a constant air voids content equal to 5%. Experimental results showed that C&D materials can conveniently be used in asphalt concrete for base layers (up to maximum 30 %) without penalizing the mechanical performance of the mixture. © RILEM 2016.

Coping with multiple false identities, also known as a Sybil attack, is one of the main challenges in securing structured peer-to-peer networks. Poisoning routing tables through these identities may make the process for storing and retrieving resources within a DHT (Distributed Hash Table) extremely difficult and time consuming. We investigate current possible countermeasures and propose a novel adaptive method for making the storage and retrieval process, in a Kademlia-based network, more secure. This is done through the use of a trust-based storage algorithm, exploiting reputation techniques. Our solution shows promising results in thwarting a Sybil attack in a Kademlia network, also in comparison with similar methods. © 2015 IEEE.


This article analyses the role of organizations’ ideological affiliation in shaping information networks within civil society and in granting access to the political sphere. It investigates whether the Catholic and Leftist affiliation of organizations impacts in the city of Turin (Italy) and Kielce (Poland). Applying different social network analysis techniques, the article finds that in both cities there is a tendency towards preferring similar partners. However, while the influence of affiliation is relevant to predict the access to policy making in Turin, in Kielce, this influence is mediated by the actor’s centrality in the social sphere. In both cities, networks are characterized by the higher centrality of Catholic organizations, which also translate in a greater involvement in the political sphere. Twenty-five years after the end of the cold war, past-affiliation is still a strong predictor of political involvement and impacts on the shape of local governance structure. © 2016 International Society for Third-Sector Research and The Johns Hopkins University
