    The last two decades have seen an unprecedented explosion in the number of civil society organizations seeking to influence national and international policy making and implementation. Global leaders, activists, scholars, and policy experts have increasingly called for the inclusion of civil society in international governance and in the national implementation of international commitments. Most recently, the wave of civil uprisings that swept the Middle East and North Africa has put fostering civil society participation high on the agenda of national governments and international organizations. Indeed, most international organizations have devised mechanisms to engage with civil society and regard civil society participation as contributing to their legitimacy, accountability, and effectiveness. The meaning of civil society, however, is deeply ambiguous. It has been interpreted in a variety of ways reflecting conflicting underlying normative values and commitments. International organizations have used the term civil society inconsistently, betraying this lack of consensus and clarity about its meaning. For example, in his address to the General Assembly urging international organizations to engage civil society in global governance, then U.N. Secretary-General Boutros Boutros-Ghali defined civil society as encompassing all nongovernmental entities, including business and industry. In contrast, the International Monetary Fund (IMF) excludes individual profit-oriented enterprises from its definition of civil society but includes business forums that aggregate and lobby on behalf of private, for-profit business interests. An official U.N. Report on United Nations-Civil Society relations (the Cardoso Report) adopts a narrower definition that excludes industry lobby groups and business federations. Some international organizations and supranational bodies, such as the World Health Organization, appear to use the terms civil society and non-governmental organizations (NGOs) interchangeably, and to favor the participation of nationally and internationally recognized NGOs in policy making and enforcement. Yet other international bodies, such as the World Bank, focus on the role of local civic associations in developing the capacity of citizens to participate in public life

    In this paper we report our experience, related to the online training for the Italian and International Olympiads in Informatics. We developed an interactive online system, based on CMS, the grading system used in several major programming contests including the International Olympiads in Informatics (IOI), and used it in three distinct context: training students for the Italian Olympiads in Informatics (OII), training teachers in order to be able to assist students for the OII, and training the Italian team for the IOI. The system, that is freely available, proved to be a game changer for the whole italian olympiads in informatics ecosystem: in one year, we almost doubled the participation to OII, from 13k to 21k secondary school students. The system is developed basing on the Contest Management System (CMS, http://cms- dev.github.io/), so it is highly available to extensions supporting, for instance, the pro- duction of feedback on problems solutions submitted by trainees. The system is also freely available, with the idea of allowing for support to alternative necessities and developmen

    The aim of the present doctoral project was to investigate the physical and structural changes occurring in biological tissue treated with microwave thermal ablation procedures, focusing the study on the evaluation and characterization of the shrinkage of the tissue, in correlation with the influence of the thermal changes. When the project started in 2013, few studies were conducted to comprehend the shrinking phenomenon (Diaz et al., 2008, Brace et al., 2009, Ganguli et al., 2008, Planché et al., 2013, Brace et al., 2010]. Nevertheless, the subject was of high interest for physicians and scientists involved in this field. The results reported from preliminary studies underlined that the volume occupied by the ablated tissue as measured at the end of the thermal ablation procedure is smaller than the volume occupied by the equivalent untreated tissue. Therefore, it resulted important to be able to adequately characterize the shrinkage of the tissue during a microwave thermal ablation procedure in order to correctly predict the true treatment volume; otherwise, the treatment safety as well as the efficacy can be compromised exposing peripheral structures to unwanted heating and affecting the assessment of the treatment’s technical success. The analysis and study of the thermally ablated tissue led mainly to perform extensive experimental investigations. Accordingly, ex vivo studies were conducted at four different laboratories: the Laboratory of the Division of Health Protection Technologies, ENEA Casaccia Research Centre, Rome (Italy); the Radiology Dept. of Regina Elena National Cancer Institute, Rome (Italy); the R&D laboratory of HS Hospital Service SpA, Aprilia (Italy); the Applied Radiology Laboratory of Hadassah Hebrew University Medical Center, Jerusalem (Israel), where I stayed for 6 months as visiting scholar. Moreover, thanks to the COST support, the laboratory of the Institute of Microbiology of the Academy of Sciences, Prague (Czech Republic), hosted me during a Short Term Scientific Mission (STSM) to conduct in vivo experiments of dielectric spectroscopy in the framework of a newborn joint scientific collaboration. In the present thesis, the conducted work is illustrated following the speculative project development. Specifically, the first chapter introduces the microwave ablation therapy, its operating principles, clinical and experimental applications and gaps; the second chapter concerns the used devices and the setups developed to conduct the experimental trials; and the third chapter illustrates the conducted experiments and their results. Finally, the outcomes are discussed in the conclusive chapter

    Use of physical activity questionnaires in people with dementia: a scoping review

    Get PDF
    Physical activity questionnaires are an important means to assess habitual physical activity. It remains unclear what questionnaires are used and whether they are appropriate for people with dementia who have impaired information recall but are also often largely sedentary. This scoping review aimed to identify and quantify the use of physical activity questionnaires within a dementia population. Eighteen studies met the inclusion criteria for this review. The majority of studies used questionnaires that were validated for use within an older adult population (e.g., Modified Baecke Questionnaire for the Elderly), though none had specifically been validated for use in people with dementia. Interestingly, just over half of studies (N= 10, 55.6%) adapted the questionnaires from the original validated version by allowing a proxy to provide input into the responses. Future research needs to robustly validate the use of proxy-report measures of physical activity in people with dementia

    Dielectric Properties of Healthy Ex-Vivo Ovine Lung Tissue at Microwave Frequencies

    Get PDF
    Knowledge of dielectric properties of lung tissue is fundamental for the improvement of lung disease diagnostics and therapeutic solutions (e.g. microwave imaging and microwave thermal ablation treatment). Although lung disease rates are increasing, lung tissue remains one of the least characterized tissues due to its heterogeneity, variability in air content, and handling difficulties. In this work, dielectric properties of ex-vivo ovine lung tissue samples were measured in the frequency range 500 MHz – 8 GHz, together with measurements of sample density (air content). Different Cole-Cole models were applied to the measured dielectric properties values. The best fitting model was chosen, and results were compared with available literature. Furthermore, the dielectric property measurements were correlated with the air content of the samples. Updated Cole-Cole models for lung tissue of different density is provided in the 500 MHz – 8 GHz range. The existence of air content threshold in lung is shown. Below this limit, the properties begin to change drastically with the change in densit

    Hydrides as high capacity anodes in lithium cells: an Italian “Futuro in Ricerca di Base FIRB-2010” project

    Automotive and stationary energy storage are among the most recently-proposed and still unfulfilled applications for lithium ion devices. Higher energy, power and superior safety standards, well beyond the present state of the art, are actually required to extend the Li-ion battery market to these challenging fields, but such a goal can only be achieved by the development of new materials with improved performances. Focusing on the negative electrode materials, alloying and conversion chemistries have been widely explored in the last decade to circumvent the main weakness of the intercalation processes: the limitation in capacity to one or at most two lithium atoms per host formula unit. Among all of the many proposed conversion chemistries, hydrides have been proposed and investigated since 2008. In lithium cells, these materials undergo a conversion reaction that gives metallic nanoparticles surrounded by an amorphous matrix of LiH. Among all of the reported conversion materials, hydrides have outstanding theoretical properties and have been only marginally explored, thus making this class of materials an interesting playground for both fundamental and applied research. In this review, we illustrate the most relevant results achieved in the frame of the Italian National Research Project FIRB 2010 Futuro in Ricerca “Hydrides as high capacity anodes in lithium cells” and possible future perspectives of research for this class of materials in electrochemical energy storage devices
