Towards evaluation design for smart city development

Smart city developments integrate digital, human, and physical systems in the built environment. With growing urbanization and widespread developments, identifying suitable evaluation methodologies is important. Case-study research across five UK cities - Birmingham, Bristol, Manchester, Milton Keynes and Peterborough - revealed that city evaluation approaches were principally project-focused with city-level evaluation plans at early stages. Key challenges centred on selecting suitable evaluation methodologies to evidence urban value and outcomes, addressing city authority requirements. Recommendations for evaluation design draw on urban studies and measurement frameworks, capitalizing on big data opportunities and developing appropriate, valid, credible integrative approaches across projects, programmes and city-level developments

An analytical framework to nowcast well-being using mobile phone data

An intriguing open question is whether measurements made on Big Data recording human activities can yield us high-fidelity proxies of socio-economic development and well-being. Can we monitor and predict the socio-economic development of a territory just by observing the behavior of its inhabitants through the lens of Big Data? In this paper, we design a data-driven analytical framework that uses mobility measures and social measures extracted from mobile phone data to estimate indicators for socio-economic development and well-being. We discover that the diversity of mobility, defined in terms of entropy of the individual users' trajectories, exhibits (i) significant correlation with two different socio-economic indicators and (ii) the highest importance in predictive models built to predict the socio-economic indicators. Our analytical framework opens an interesting perspective to study human behavior through the lens of Big Data by means of new statistical indicators that quantify and possibly "nowcast" the well-being and the socio-economic development of a territory

Suited for spacewalking: A teacher's guide with activities

This publication is an activity guide for teachers on spacesuits and spacewalking. It uses the intensive interest many children have in space exploration as a launching point for hands-on-opportunities. The guide begins with brief discussions of the space environment, the history of space walking, the Space Shuttle spacesuit, and working in space. These are followed by a series of activities that enable children to explore the space environment as well as the science and technology behind the functions of spacesuits. The activities are not rated for specific grade levels because they can be adapted for students of many ages. The guide concludes with a brief glossary as well as references and resources

Fiscal Year 2015 Walmart and Walmart Foundation Giving Report

Walmart and the Walmart Foundation have released the Fiscal Year 2015 (FY2015) Giving Report highlighting the company and the Foundation's strategic giving programs. Walmart works to serve society by helping customers save money, employing millions of associates and taking on global responsibility initiatives designed to reduce waste, lower greenhouse gas emissions and enhance the sustainability of food and other supply chains. Through its giving efforts, Walmart has systematically addressed large-scale environmental and social challenges in three priority areas: opportunity, sustainability and community.In FY2015, Walmart and the Walmart Foundation donated more than $1.4 billion in cash and in kind. Walmart associates also contributed more than 1.5 million hours of their time outside of work to volunteer causes. In addition to cash grants, each program mentioned in the report draws on Wal-Mart's strengths, such as in-kind donations (especially of food), the expertise and passion of its 2.2 million associates around the world, engagement of Walmart customers and last but not least partnerships with suppliers, civil society and government agencies

Costa Rica, superstar? some reflections on the global drivers and bottlenecks of the happy planet index

For some years now, the Happy Planet Organization presents the so-called ‘Happy Planet Index’ (HPI), which is an index of measuring the trade-off between ecological footprint data and life quality (Happy Life Years, HLYE). Costa Rica emerges from these comparisons as the world’s ‘best practice nation’, using a minimum amount of natural resources to achieve a maximum of human happiness. So is Costa Rica the pathway for humanity? There are shortcomings in the formula, with which the index is calculated (Happy Life Years divided by Ecological Footprint per capita, and some constants added). Using a re-formulation, the global ranking with Costa Rica on top is indeed confirmed. We present some evidence on the cross-national drivers and bottlenecks of our re-formulated Happy Planet Index (HPI) performance on a global scale: a wide variety of standard globalization variables have little influence on HPI performance. Big countries with large population resources perform somewhat better, and low military expenditures per GDP are a constraint on HPI performance. Beneficial effects are also wielded by received worker remittances. Efficiency tends to increase and then to decrease with rising development levels.Ecological and environmental phenomena; ecological footprint; globalization; Happy Planet Index; inequality; migration; military expenditures

Superprocesses as models for information dissemination in the Future Internet

Future Internet will be composed by a tremendous number of potentially interconnected people and devices, offering a variety of services, applications and communication opportunities. In particular, short-range wireless communications, which are available on almost all portable devices, will enable the formation of the largest cloud of interconnected, smart computing devices mankind has ever dreamed about: the Proximate Internet. In this paper, we consider superprocesses, more specifically super Brownian motion, as a suitable mathematical model to analyse a basic problem of information dissemination arising in the context of Proximate Internet. The proposed model provides a promising analytical framework to both study theoretical properties related to the information dissemination process and to devise efficient and reliable simulation schemes for very large systems
