    It is widely recognized that white spaces identification is an important milestone for the wide deployment of next generation cognitive wireless networks. However, spectrum holes detection tools used for white spaces discovery are still either in the infancy stage or too expensive to enable massive white spaces exploitation. Building upon cheap hardware equipment, this paper presents experiments conducted in the town of Trieste in Italy to sense the environment and find out which frequencies are not being used in a particular place and time-of-the-day. As a first step towards white spaces exploitation, we believe that our experimental frequency exploration is an important milestone upon which white spaces patterns recognition will be built with the aim of using these patterns in wireless network planning and management

    Creating Spaces: Performing Artists in Sacred Spaces: Austin, Baltimore, Detroit

    Ewing This study builds upon a successful pilot program of Partners for Sacred Places that facilitates long-term, mutually beneficial space-sharing relationships between arts organizations -- with inadequate or no home space -- and houses of worship with space to share. The findings of this study demonstrate a range of issues, challenges, and opportunities facing performing artists and clearly establish that these artists:overwhelmingly see a need for more performance, rehearsal, and administrative spaces;see a home space as critical to artistic development and community engagement; andfeel that a historic sacred space could enhance the experience of their work.This research confirms that many sacred spaces face diminished membership, limited resources to support and maintain their facilities, and a desire to provide value as a community resource and asset, but lack the resources to create these links. The findings from each city establish a significant amount of available space, the desire of sacred spaces to serve as a broader community asset, and their minimal concerns about artistic content and control. This report and its findings could have implications for artists, sacred spaces, and the funding community not only in the three cities studied, but also throughout the country

    Food System and Food Security Study for the City of Cape Town

    Food insecurity is a critical, but poorly understood, challenge for the health and development of Capetonians. Food insecurity is often imagined as hunger, but it is far broader than that. Households are considered food secure when they have “physical and economic access to sufficient and nutritious food that meets their dietary needs and food preferences for an active and healthy life” (WHO/FAO 1996). Health is not merely the absence of disease, but also encompasses good nutrition and healthy lifestyles. Individuals in a food insecure household and/or community are at greater risk due to diets of poor nutritional value, which lowers immunity against diseases. In children, food insecurity is known to stunt growth and development and this places the child in a disadvantaged position from early on in life. Any improvement in the nutritional profile of an individual is beneficial and as the family and community become more food secure, the greater the benefit. It further reduces the demand on health services. In the Cape Town context, food insecurity manifests not just as hunger, but as long term consumption of a limited variety of foods, reduction in meal sizes and choices to eat calorie dense, nutritionally poor foods in an effort to get enough food to get by. Associated with this food insecurity are chronic malnutrition and micronutrient deficiency, particularly among young children, and an increase in obesity, diabetes and other diet related illnesses. Food insecurity is therefore not about food not being available, it is about households not having the economic or physical resources to access enough of the right kind of food. The latest study of food insecurity in Cape Town found that 75 percent of households in sampled low-income areas were food insecure, with 58 percent falling into the severely food insecurity category. Food insecurity is caused by household scale characteristics, such as income poverty, but also by wider structural issues, such as the local food retail environment and the price and availability of healthy relative to less healthy foods. The City of Cape Town therefore commissioned a study based on the following understanding of the food security challenge facing the City. “Food security or the lack thereof is the outcome of complex and multi-dimensional factors comprising a food system. Therefore, food insecurity is the result of failures or inefficiencies in one or more dimensions of the food system. This necessitates a holistic analysis of the food system that than can provide insights into the various components of the system, especially in our context as a developing world city.” The call for a food system study sees the City of Cape Town taking the lead nationally, being the first metropolitan area to seek to engage in the food system in a holistic manner and attempting to understand what role the city needs to play in the food system. The City must work towards a food system that is reliable, sustainable and transparent. Such a system will generate household food security that is less dependent on welfarist responses to the challenge. In this context, reliability is taken to mean stable and consistent prices, the nutritional quality of available and accessible food, and food safety. Sustainability means that the food system does not degrade the environmental, economic and social environment. Finally, transparency refers to the legibility of the system and its control by the state and citizens

    Social Justice in Architecture: Building of a New Research Model

    Get PDF
    Architecture’s historic search to create social justice is a source of much contention. The inherent broadness in the definition of social justice and the diverse architecture methods to create it lead to the notion that a research framework to properly address social justice in architecture does not exist. Although an architect’s ability to act within professional practice is based on knowledge of a repertoire of cases - a Case Study Model - this generalized contemporary research model does not provide a specific framework for investigators to properly understand and analyze social justice in architecture. Thus, in order to create a new research model with specificity to social justice in architecture, a critical analysis of existing knowledge on social justice and its link to the architecture profession is necessary. A critique of diverse methods stemming from the design or planning of architecture, as well as an analysis of the Case Study Model and its application to four case studies, are conducted in this dissertation. The consequent observations that result from research directly inform a new research framework, the Social Justice in Architecture Model. The architectural implications of this new framework compose a cohesive research model to understand and analyze social justice in architecture

    Engaging youth in community health needs assessments: what are the opportunities, methodological approaches, contributions, and feasibility?

    Get PDF
    Community engagement in health assessment enables researchers to better understand and prioritize community needs. The value of community engagement is increasingly documented; however, few studies engage youth. Research and assessments are often done for youth, but not with youth. Youth bring a unique contextual lens to community issues; without engagement, the likelihood that resultant efforts would be accepted by or appropriate for youth decreases. This dissertation explores opportunities and methodological approaches for, and contributions and feasibility of engaging youth in non-profit hospital community health needs assessments (CHNAs) mandated through the Affordable Care Act. This study has three specific aims, utilizing multiple methodological approaches: • Aim 1: Assess the current level of youth engagement, and prevalence of youth-focused priority areas in Massachusetts CHNAs. CHNAs were reviewed and analyzed using the Community Health Improvement Data Sharing System’s community engagement template. • Aim 2: Compare assessment results of focus groups and participatory photo mapping (PPM) in documenting youth observations of Boston community conditions. Three focus groups and PPM processes engaged 46 high-school age youth. Data were qualitatively compared, with attention to youth-identified community assets, concerns, and recommendations. • Aim 3: Compare youth results with existing CHNAs and identify potential contributions of youth engagement. Using the social determinants of health framework, youth recommendations were compared to Boston hospital community health improvement (CHI) publications to observe the convergence and divergence of priorities. While all MA hospitals minimally complied with required CHNA community engagement criteria, there was no standard practice or approach. 20% of CHNAs engaged youth, primarily through focus groups; yet, 80% of CHNAs that identified priorities included youth-focused priorities. Youth-driven results focused upon social determinants of health factors; furthermore, PPM results provided more detailed and granular CHI recommendations. Youth-identified CHI recommendations complemented those identified by hospitals, indicating that youth engagement can potentially strengthen CHI priorities and identify salient strategies for addressing youth health, specifically. Findings can be extrapolated to the many institutions conducting assessments, including health departments and Community Action Agencies. Findings will be disseminated through a series of practice briefs that make recommendations to hospitals, assessment practitioners, and youth organizations to consider for future efforts
