The Eu

Within the EU CEMEC project framework, a novel approach for using holographic showcases in museums has been conceived and experimented upon in different venues in the context of an itinerant exhibition dealing with Early Medieval European collections. The purpose of this holographic showcase, the so-called “box of stories”, is to improve the link and interaction between real and virtual contents in the museum’s context, making the exhibited object “alive” in the visitors’ perception. An Avar sword and a Byzantine treasure have been used as the main case studies, and they have been experienced in the museums of several European regions by audiences with different cultural backgrounds. This has been a great opportunity to carry out user experience (UX) evaluations in order to collect feedback (from about 600 museum visitors) regarding the attractiveness of such a mixed reality (MR) system, its usability, the comprehension of the contents, the efficacy of the logistics and environmental conditions, as well as the educational impact. The results of such inquiries helped the CNR ISPC team to identify the most meaningful User eXperience Analytics (UXA) able to support the work of UX evaluators and UX designers to assess the efficacy of digital cultural products. Indeed, this manuscript presents UXA and tries to draft a concrete and effective evaluation model for future digital projects for museum contexts.

AbstractThe increase in the world population leads to rising demand and consumption of plastic raw materials; only a small percentage of plastics is recovered and recycled, increasing the quantity of waste released into the environment and losing its economic value. The plastics represent a great opportunity in the circular perspective of their reuse and recycling. Research is moving, on the one hand, to implement sustainable systems for plastic waste management and on the other to find new non-fossil-based plastics such as polyhydroxyalkanoates (PHAs). In this review, we focus our attention on Tenebrio molitor (TM) as a valuable solution for plastic biodegradation and biological recovery of new biopolymers (e.g. PHA) from plastic-producing microorganisms, exploiting its highly diversified gut microbiota. TM’s use for plastic pollution management is controversial. However, TM microbiota is recognised as a source of plastic-degrading microorganisms. TM-based plastic degradation is improved by co-feeding with food loss and waste as a dietary energy source, thus valorising these low-value substrates in a circular economy perspective. TM as a bioreactor is a valid alternative to traditional PHA recovery systems with the advantage of obtaining, in addition to highly pure PHA, protein biomass and rearing waste from which to produce fertilisers, chitin/chitosan, biochar and biodiesel. Finally, we describe the critical aspects of these TM-based approaches, mainly related to TM mass production, eventual food safety problems, possible release of microplastics and lack of dedicated legislation.

New and emerging technology in the field of virtual environments has permitted a certain malleability of learning milieus. These emerging environments allow learning and transfer through interactions that have been intentionally designed to be pleasurable experiences. TLE TeachLivE™ is just such an emerging environment that engages teachers in practice on pedagogical and content aspects of teaching in a simulator. The sense of presence, engagement, and ludus of TLE TeachLivE™ are derived from the compelling Mixed Reality that includes components of off-the shelf and emerging technologies. Some of the noted features that have been identified relevant to the ludic nature of TeachLivE include the flow, fidelity, unpredicability, suspension of disbelief, social presence, and gamelike elements. This article explores TLE TeachLivE™ in terms of the ludology, paideic user experience, the source of the ludus, and outcomes of the ludic nature of the experience.

Depth Analysis

With the rapid development of e-commerce technology, cross-channel consumption has become the mainstream mode of contemporary consumers. However, there are several problems of cross-channel consumption such as inconsistency of online and offline channel information and service, disfluency of channel switching which have brought adverse effects on user experience. The question arises here as to what factors influence user experience and how to build a scientific and effective evaluation index system. Different from previous studies based on sellers, this paper used grounded theory to analyze and summarize the evaluation index system of user experience under cross-channel consumption from the perspective of consumers. We summarized and refined four first level indexes which are “online platform attribute, offline entity attribute, channel switching attribute, and individual demand” and 13 second level indexes which are “platform operation, platform information, platform service, platform promotion, product quality, service quality, environment quality, channel consistency, channel switching cost, channel switching fluency, psychological expectation, personal interests and individual needs.” Then, we used BP neural network to build the evaluation model and trained and simulated the performance of the sample. The results show that the evaluation model has a good generalization ability and can effectively evaluate user experience under cross-channel consumption. Finally, implications and limitations are also discussed. This study helps to enrich the theoretical research on user experience and consumer behavior. It also provides targeted basis for in-depth analysis of cross-channel consumption behavior, establishment of user experience evaluation index system, and improving user experience and multichannel management of physical stores.

Green Investments

The new and more conscious sensibility towards the environmental sphere supports the idea of “green city”, promotes initiatives of structural integration of the green with the built environment and involves a considerable number of disciplines in a cultural and social debate. The literature reports different experiences of collaborative governance, between administrations and citizens, which tend to enhance the interaction between the different social actors involved in the investments of Green Infrastructures, to share objectives and management methods and to assess the extent of ecosystem services. The objective of this article is to propose a methodological approach to assessing green investments in the urban area, which is able to internalize the social perception of citizens regarding this important component for the urban landscape, with a view to guiding the city’s government towards a new urban eco-social-green planning and evaluation model. It presents a concise framework of the scientific debate on climate change and on the effects of urban planning issues; some relevant experiences of Green Infrastructures; and the proposed methodology, applied to the reality of the “urban green system” of Catania, based on an integrated approach between participatory planning and the method NAIADE (Novel Approach to Imprecise Assessment and Decision Environments).

At the current stage of its evolution, the European Union (“Union” or “EU”) has reached a juncture where many leaders and scholars believe that greater integration is both desirable and necessary. Presumably, a primary method by which greater solidarity and integration can be achieved within the EU is through the public inclusion of common value-laden concepts – as defined through a dialectical process – present within comprehensive doctrines such as religion. To date, however, an effective and inclusive means for utilizing religion in this manner has yet to be formulated. In response, this article takes two prominent paradigms – Jurgen Habermas' intersubjective discourse theory and John Rawls' liberalism – to approach the problem and draws from them a new solution that, while tied to their theoretical underpinnings, is nonetheless a novel approach to achieving greater integration within the Union. Under this new framework, the process of legislatively defining human rights allows the morality common to European comprehensive doctrines – including official and unofficial religions – to bolster the Union's solidarity, legitimacy, and democracy both procedurally and substantively.
