The brain: What is critical about it?

We review the recent proposal that the most fascinating brain properties are related to the fact that it always stays close to a second order phase transition. In such conditions, the collective of neuronal groups can reliably generate robust and flexible behavior, because it is known that at the critical point there is the largest abundance of metastable states to choose from. Here we review the motivation, arguments and recent results, as well as further implications of this view of the functioning brain.Comment: Proceedings of BIOCOMP2007 - Collective Dynamics: Topics on Competition and Cooperation in the Biosciences.

The Experience-Oriented Tourism in Tuscan Rural Areas

Despite the present scenario of general economic uncertainty, Tuscan rural spaces are still appealing to tourists from Italy and abroad. The changes which took place in the early 1990’s are still evolving in these rural places, where farmers are adapting their supply to the demand of this changing market. In fact, nowadays, there still is a tourist demand for an old-style holiday in rural spaces which is based on the attraction towards natural places and genuine food, while a demand for a more stunning lamorous-style holiday is increasing. The widespread presence of farms involved in tourism is sizable, with more than 4,000 farms (and about 52,000 beds) recorded in 2011, which were dispersed around places with valued cultural landscape and places with valued cultural landscape and linked to apreciated and certified products which in some areas are the pivotal resources. Rethinking rural tourism and agritourism through a wider range of integrated and customized services and looking at rural areas from a different perspective represent two important strategies in order to implement the experience-oriented tourism in the countryside too

The Importance of Place Names in the Sustainable Tourist Development of the Inland Areas of Tuscany : Toponyms along the Via Francigena

The study of place names, through appropriate both linguistic and geographical tools (topographic I.G.M. maps; Environmental Information System of Regione Toscana, etc.) makes come up hidden identities in geographical areas that can be exploited because of their cultural heritage or their landscape. Sometimes the discovery of old linguistic remains is essential to understand the meaning and the role of places and of buildings linked to a past living of some ethnic groups who unconsciously let somewhere their marks. The Italian Peninsula is rich in particular place names, due to the passage of people both from the North and from the Mediterranean Sea in different periods and for different purposes. In Tuscany, too, some areas do exist which have a cultural heritage depending on ancestral presences that can be still revealed: the study of toponyms, in fact, is an effective way to understand the origins and the role of places, the interaction between man and the territories where he lived, the historical and geographical changes. Toponyms are able to let us understand the identity and the uniqueness of a place, reveal us the sense of place and build a cultural base in order to make local institutions awere of it, bringing them to apply for a valorization of economically weak regions. In particular we will deal with the path of Via Francigena in Tuscany, between Lunigiana and Val d’Orcia, where we find some economic important areas since their origins, rich in resources and cultural quality; some other ones considered “minor” but vital enough thanks to the new rural policy; and, at last, some other marginal areas

CIARD Activities in the CGIAR: Final Report on activities, outputs and lessons from the implementation of the CIARD grant to the CGIAR

CIARD activities for the CGIAR have been led by the CGIAR ICT-KM program, which has worked closely with scientists, researchers, research managers and information and communication specialists across the CGIAR: Centers, Programs and projects. This document reports on activities implemented by the CGIAR ICT-KM program through a grant (PO245548) from FAO, originally from the DFID CIARD grant, but is based on activities being undertaken by Centres, Programs and projects of the CGIAR. Special acknowledgement and appreciation is given to ILRI for hosting the CIARD CGIAR grant coordinator and its great support to learning, documentation and promotion of CIARD principles and pathways

Sol-gel synthesis of spherical monodispersed bioactive glass nanoparticles co-doped with boron and copper

In this work, an optimized sol-gel process for the synthesis of spherical and monodispersed bioactive glass nanoparticles doped with boron and copper was developed, by investigating different synthesis parameters. The obtained glasses were characterized in terms of morphology, composition, dispersibility, structure and in vitro reactivity. The performed characterizations demonstrated that shape, dimension and dispersion can be tailored by acting on the timing of the addition of the catalyst and on the synthesis process, in particular the centrifugation step. The optimized glass particles showed a spherical shape, good ions incorporation and good dispersion. In vitro bioactivity test demonstrated that the boron and copper addition did not interfere with the glass ability to induce the precipitation of hydroxyapatite. The shape, dispersion, bioactive behavior and content of boron and copper of these novel bioactive glass particles make them very promising for both hard and soft tissue engineering applications

Neurophysiological Profile of Antismoking Campaigns

Over the past few decades, antismoking public service announcements (PSAs) have been used by governments to promote healthy behaviours in citizens, for instance, against drinking before the drive and against smoke. Effectiveness of such PSAs has been suggested especially for young persons. By now, PSAs efficacy is still mainly assessed through traditional methods (questionnaires and metrics) and could be performed only after the PSAs broadcasting, leading to waste of economic resources and time in the case of Ineffective PSAs. One possible countermeasure to such ineffective use of PSAs could be promoted by the evaluation of the cerebral reaction to the PSA of particular segments of population (e.g., old, young, and heavy smokers). In addition, it is crucial to gather such cerebral activity in front of PSAs that have been assessed to be effective against smoke (Effective PSAs), comparing results to the cerebral reactions to PSAs that have been certified to be not effective (Ineffective PSAs). &e eventual differences between the cerebral responses toward the two PSA groups will provide crucial information about the possible outcome of new PSAs before to its broadcasting. &is study focused on adult population, by investigating the cerebral reaction to the vision of different PSA images, which have already been shown to be Effective and Ineffective for the promotion of an antismoking behaviour. Results showed how variables as gender and smoking habits can influence the perception of PSA images, and how different communication styles of the antismoking campaigns could facilitate the comprehension of PSA’s message and then enhance the related impac

Urban-Rural Links for Sustainable Food Consumption in Bangkok

Current food systems fail to directly link urban consumers with rural producers. City-regional strategies need to reconnect consumers with producers through sustainable local food systems. This research developed and distributed a survey questionnaire to 400 consumers in Bangkok. Findings prove that there is a statistically significant association between urban-rural relation and sustainable urban consumer behavior (Pearson’s Chi-square test for independence resulting in a significance level of p < 0.05). Sustainable consumer behavior is influenced by environmental, sociocultural, economic and health drivers, while lack of food traceability, lack of rural experience, lack of access to rural communities and negative social perception disrupt consumer-producer links. Community-based gastrotourism emerges as one of the best practices to link urban consumers with rural producers and plan sustainable food systems in mega-cities like Bangkok
