miramap a collective awareness platform to support open policy making and the integration of the citizens perspective in urban planning and governance
The chapter intends to explore an innovative approach for a more inclusive and sustainable urban planning and governance through the use of the ICT matched with a participatory process. It describes the transition process from a pilot project (Crowdmapping Mirafiori Sud/CMMS) headed by the Politecnico di Torino in 2013 in the Mirafiori Sud district of Turin (Italy)âwhose aim was to design and test an open-source crowdmapping platform to identify and categorize, aggregating large amounts of user-generated inputs, the nature, the location and the consistency of the obstacles, which prevent vulnerable categories to use the public space in their neighbourhoodâto the set up of a proper governing tool (MiraMap) to enhance open policy-making and the integration of the citizens' perspective through their effective engagement. Such platform is expected to have very concrete impacts both in empowering citizens, supporting grassroots processes and practices, sharing knowledge and in allowing policy options and design to become more informed and targeted. The methodology and the technological implementation supporting the creation of the platform have been developed by a multidisciplinary research team (urban planners, architects, sociologists, engineers, computer scientists, legal experts) in consultation withâand with the support ofâthe local public administration and the community-based organizations
Comparison of TCP and TCP/HA Hybrid Scaffolds for Osteoconductive Activity
Two types of porous ceramic scaffolds were prepared, consisting of ÎČ-tricalcium phosphate (TCP) or the mixed powder of TCP and hydroxyapatite (HA) at a 2:1 mass ratio. A variety of methods have been used to fabricate bone scaffolds, while the sintering approach was adopted in this work. An extremely high temperature was used on sintering that proposed to consolidate the ceramic particles. As revealed by SEM, a well opened pore structure was developed within the scaffolds. The Ξ-values were measured to be of 73.3° and 6.5° for the composite scaffold and TCP sample, respectively. According to XRD patterns, the existence of grains coalescence and partial bonding between HA and TCP powders was demonstrated. Scaffold mechanical property in the term of flexural strength was also determined. The result showed decreasing of the strength by HA supplement, suggesting the more brittle characteristic of HA in comparison with TCP. By soaking the composite scaffold in PBS for a period of 2 weeks, transformation from particles to flank-like crystalline was clearly observed. Such change was found to be favorable for cell attachment, migration, and growth. By implanting cell-seeded scaffolds into nude mice, an abundant osseous extracellular matrix was identified for the composite implants. In contrast, the matrix was minimally detected in TCP implanted samples. Thus, the composite scaffold was found superior for hard tissue regeneration
Treatment of migraine attacks based on the interaction with the trigemino-cerebrovascular system
Primary headaches such as migraine are among the most prevalent neurological disorders, affecting up to one-fifth of the adult population. The scientific work in the last decade has unraveled much of the pathophysiological background of migraine, which is now considered to be a neurovascular disorder. It has been discovered that the trigemino-cerebrovascular system plays a key role in migraine headache pathophysiology by releasing the potent vasodilator calcitonin gene-related peptide (CGRP). This neuropeptide is released in parallel with the pain and its concentration correlates well with the intensity of the headache. The development of drugs of the triptan class has provided relief for the acute attacks but at the cost of, mainly cardiovascular, side effects. Thus, the intention to improve treatment led to the development of small CGRP receptor antagonists such as olcegepant (BIBN4096BS) and MK-0974 that alleviate the acute migraine attack without acute side events. The purpose of this review is to give a short overview of the pathological background of migraine headache and to illustrate the mechanisms behind the actions of triptans and the promising CGRP receptor blockers
What sustainable development for the cities of the South? Urban issues for a third millennium
Risk Management of Groundwater Pollution, Sustainability and Quality of Life: The Gap Between Theory and Practice in an Intermediate City of the Global South (Mar Del Plata, Argentina)
Within the multiple approaches to the concept of quality of life, access to safe water is, directly or indirectly, part of the variables that define its components. However, this ability to access safe water brings into play the environmental, socio-cultural, political and economic dimensions of sustainability. Thus, this chapter aims to analyze the relationship between sustainability and quality of life from the groundwater pollution risk management perspective, comparing policies (âwhat it should beâ) with practice (âwhat it really isâ) in each stage of the groundwater pollution risk management process (assessment, prediction, prevention and warning system), as well as proposing adjustment actions for the study case of an intermediate city of the Global South. Mar del Plata is a Global South intermediate city, where groundwater is the only water supply source. The city presents a sizeable peri-urban area, where multiple land uses have been developed; this development increases the occurrence of pollution processes because the majority of this area lacks water and sanitation systems. Hence, the policy aspect was reviewed from international and national guidelines and laws, while practice was obtained from semi-structured interviews. The main reasons that explain the gap between policy and practice are related to political, administrative, information, funding and accountability factors. As such, adjustment actions were proposed for the study area to reduce those gaps.Fil: Barilari, Agustina. Universidad Nacional de Mar del Plata. Facultad de Ciencias Exactas y Naturales.
