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

Major depressive disorder (MDD) is a multifactorial and polygenic disorder, where multiple and partially overlapping sets of susceptibility genes interact each other and with the environment, predisposing individuals to the development of the illness. Thus, MDD results from a complex interplay of vulnerability genes and environmental factors that act cumulatively throughout individual's lifetime. Among these environmental factors, stressful life experiences, especially those occurring early in life, have been suggested to exert a crucial impact on brain development, leading to permanent functional changes that may contribute to lifelong risk for mental health outcomes. In this review, we will discuss how genetic variants (polymorphisms, SNPs) within genes operating in neurobiological systems that mediate stress response and synaptic plasticity, can impact, by themselves, the vulnerability risk for MDD; we will also consider how this MDD risk can be further modulated when gene × environment interaction is taken into account. Finally, we will discuss the role of epigenetic mechanisms, and in particular of DNA methylation and miRNAs expression changes, in mediating the effect of the stress on the vulnerability risk to develop MDD. Taken together, we aim to underlie the role of genetic and epigenetic processes involved in stress- and neuroplasticity-related biological systems on the development of MDD after exposure to early life stress, thereby building the basis for future research and clinical interventions. © 2015 Lopizzo, Bocchio Chiavetto, Cattane, Plazzotta, Tarazi, Pariante, Riva and Cattaneo.

This conceptual paper considers the cooperative enterprise model in the light of how it can be affected by the digital world and-at the same time-of how it can positively affect both the Internet and its users. The aim of the paper is therefore twofold: (i) to consider the extent and the way in which cooperative principles are going to be affected by the transition of these firms towards ‘digital materiality’ [1]; (ii) to outline the potential implications of a diffusion of cooperative forms to Internet organizations and users. Based on the traits of this enterprise model, an emerging perspective is described whereby the ‘cooperative’ (especially if considered as a ‘service system’) has an interesting potential both as a competent actor in the domain of virtual enterprises and as a possible driver for safeguarding Internet users. © Springer International Publishing Switzerland 2016.

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.

Service oriented perspectives represent an opportunity of innovation and an answer to current challenges for social welfare, sustainable development and everyday life. The prevention of food waste requires new networked and collaborating competences, in the light of the increasing inefficiencies of modern economic growth models and the improvement of new paradigms for sustainable development. This research presents the case of a project that, while addressing food waste at the level of several organizations throughout the supply chain, implemented a recovering process to reduce food impairment. The project (R.e.b.u.s.) applies the efficiency system originally developed for school and university canteens to other food donors. In order to support this project, a farreaching educational program for sustainable development was started in schools, universities and through public events. By educating the local community and enhancing processes that drive a change in behaviour, this initiative proved essential for the successful prevention of food waste. © Springer International Publishing Switzerland 2016.

The article describes the mechanical design and testing of a miniaturized spherical parallel manipulator, conceived to handle the orientation of a mobile platform during the assembly of very small components. The kinematic synthesis of the device has been driven by the cooperative tasks to be performed, aiming at enlarging the orientation workspace while still keeping good static performances and a high positioning accuracy. The preliminary experimental tests carried out on the first prototype of the manipulator are presented in the paper. The perspective is to contribute to the realization of general automatic production systems at the moment absent for objects of these dimensions. © 2015, Springer Science+Business Media Dordrecht.

An important and common prerequisite of many asymmetric cryptography systems is the availability of a secure mechanism for exchanging or distributing public keys. In this paper we compare two adaptive trust-based distributed schemes to deliver public keys in a peer-to-peer network. In such a scenario, centralized solutions, for example based on a certification authority or a public key infrastructure, cannot be used. For this reason we considered a completely distributed approach creating a sort of context aware web-of-trust. This is achieved in two different trust-based manners: one considering a classic request-response scheme and another one that exploits a Distributed Hash Table (DHT). We compare performances of both solutions trying to find an optimum trade-off. © 2015 IEEE.

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
