The concepts of smart city and social innovation in combination with the increasing use of ICT by citizens and public authorities could enhance the involvement of people on the decisions that directly affect their daily life. A case study approach was adopted to illustrate the potential of civic crowdfunding for increasing the participation and collaboration between citizens, firms and government. The analysis of two exemplary cases shows that civic crowdfunding platforms could be used by public administration to engage communities in the search of solutions to local problems. Likewise, it could be used to reinforce the community ties and to leverage the bonds among the stakeholders and the partners of the community ecosystem.

El movimiento de datos abiertos es relativamente nuevo, ofrece beneficios significativos a la sociedad y a la economía, promueve la democracia y la responsabilidad de los gobiernos públicos fomentando la transparencia, participación y colaboración de los ciudadanos. Por ser un movimiento relativamente nuevo, son los países que lideran el desarrollo quienes ya han implementado políticas de datos abiertos y ya disfrutan de sus beneficios; sin embargo, hay países en los que aún ni siquiera hay iniciativas de datos abiertos o aún están comenzando. En este trabajo se estudia el uso adecuado de buenas prácticas, normas, métricas y estándares para la implantación de datos abiertos de manera sostenible, automatizable y en formatos accesibles que garanticen la reutilización de los datos con el fin de generar valor a través de ellos, al crear nuevos productos y servicios que contribuyan a mejorar la calidad de vida de los ciudadanos. En ese sentido, se realiza un análisis exploratorio de los principios de datos abiertos, se realiza un análisis sobre la situación actual de iniciativas de datos abiertos, y con el fin de que el proyecto sea de máxima aplicabilidad, se realizan pruebas de la métrica Meloda 4.0 sobre conjuntos de datos del Ayuntamiento de Madrid. Se realiza un análisis y evaluación de los portales de datos abiertos de los Ayuntamientos de Madrid, Zaragoza y Barcelona basándose en la Norma UNE 178301:2015. En concordancia con la filosofía de datos abiertos, se estudia y sugiere el uso de tecnologías de código abierto para la publicación de datos abiertos. Finalmente, como resultado y aplicabilidad de todo lo aprendido, se propone el diseño de una metodología para publicación de datos abiertos orientada a entidades públicas que aún no tienen iniciativas o están comenzando a implementar políticas de datos abiertos.

This paper evaluate the hypothesis that race is a determining factor in access to quality employment in Colombia during 2007 -- Using data from the Large Integrated Household Survey (2007-I), we estimate a generalized ordered logit model -- The results provide evidence that individuals self-identified as Afrocolombian have a higher probability of being in a low quality job than other Colombians -- This probability is higher by 1.9% in Cali, 3.4% in Bogotá, 12.6% in Barranquilla, 1.8% in Cartagena, 1.1% in Medellin and 3.8% overall in these five cities, results that could indicate that there is racial discrimination against Afrocolombians in the Colombian labor market

Suburban lifestyle is popular among American families, although it has been criticized for encouraging automobile use through longer commutes, causing heavy traffic congestion, and destroying open spaces (Handy, 2005). It is a serious concern that people living in low-density suburban areas suffer from high automobile dependency and lower rates of daily physical activity, both of which result in social, environmental and health-related costs. In response to such concerns, researchers have investigated the inter-relationships between urban land-use pattern and travel behavior within the last few decades and suggested that land-use planning can play a significant role in changing travel behavior in the long-term. However, debates regarding the magnitude and efficiency of the effects of land-use on travel patterns have been contentious over the years. Changes in built-environment patterns is potentially considered a long-term panacea for automobile dependency and traffic congestion, despite some researchers arguing that the effects of land-use on travel behavior are minor, if any. It is still not clear why the estimated impact is different in urban areas and how effective a proposed land-use change/policy is in changing certain travel behavior. This knowledge gap has made it difficult for decision-makers to evaluate land-use plans and policies. In addition, little is known about the influence of the large-scale built environment. In the present dissertation, advanced spatial-statistical tools have been employed to better understand and analyze these impacts at different scales, along with analyzing transit-oriented development policy at both small and large scales. The objective of this research is to: (1) develop scalable and consistent measures of the overall physical form of metropolitan areas; (2) re-examine the effects of built-environment factors at different hierarchical scales on travel behavior, and, in particular, on vehicle miles traveled (VMT) and car ownership; and (3) investigate the effects of transit-oriented development on travel behavior. The findings show that changes in built-environment at both local and regional levels could be very influential in changing travel behavior. Specifically, the promotion of compact, mixed-use built environment with well-connected street networks reduces VMT and car ownership, resulting in less traffic congestion, air pollution, and energy consumption.

The identification and characterisation of Cryptosporidium genotypes and subtypes are fundamental to the study of cryptosporidiosis epidemiology, aiding in prevention and control strategies. The objective was to determine the genetic diversity of Cryptosporidium in samples obtained from hospitals of Rio de Janeiro, Brazil, and Buenos Aires, Argentina. Samples were analysed by microscopy and TaqMan polymerase chain reaction (PCR) assays for Cryptosporidium detection, genotyped by nested-PCR-restriction fragment length polymorphism (RFLP) analysis of the 18S rRNA gene and subtyped by DNA sequencing of the gp60 gene. Among the 89 samples from Rio de Janeiro, Cryptosporidium spp were detected in 26 by microscopy/TaqMan PCR. In samples from Buenos Aires, Cryptosporidium was diagnosed in 15 patients of the 132 studied. The TaqMan PCR and the nested-PCR-RFLP detected Cryptosporidium parvum , Cryptosporidium hominis , and co-infections of both species. In Brazilian samples, the subtypes IbA10G2 and IIcA5G3 were observed. The subtypes found in Argentinean samples were IbA10G2, IaA10G1R4, IaA11G1R4, and IeA11G3T3, and mixed subtypes of Ia and IIa families were detected in the co-infections. C. hominis was the species more frequently detected, and subtype family Ib was reported in both countries. Subtype diversity was higher in Buenos Aires than in Rio de Janeiro and two new subtypes were described for the first time.

En Costa Rica hay seis lenguas indígenas reconocidas oficialmente. Cada una de ellas disfruta de una condición diferente en cuanto a sus tradiciones y números de hablantes, entre otras. A pesar de los esfuerzos del gobierno de Costa Rica y otros investigadores desde 1995, las lenguas han enfrentado dificultades a nivel interno y externo, las cuales han resultado en el debilitamiento o inclusive pérdida de las mismas. Esto nos lleva al caso de boruca, una de las lenguas de Costa Rica que puede ahora ser considerada una lengua extinta. Este artículo presenta una descripción general del pueblo boruca, sus tradiciones y sus principales características, y a la vez ofrece al lector una descripción tipológica general de la lengua en la cual se discuten brevemente los rasgos generales de su gramática.In Costa Rica there are six officially recognized indigenous languages. Each enjoys a different condition in terms of its traditions and number of speakers, among others. Despite efforts of the Costa Rican government and other researchers since 1995, the languages have met endogenous and exogenous difficulties that have resulted in the weakening and even loss of the languages. This leads us to what happened to Boruca, one of the indigenous languages of Costa Rica which can now be considered an extinct language. This article presents a general description of the Boruca people, their traditions and main characteristics, and it also introduces the reader to a general typological description of the language where the main features of its grammar are briefly discussed.

Australia’s inner cities experienced an upheaval in the 1960s and 70s which left them changed forever. People from all walks of life who valued their suburbs – places like Balmain, Battery Point, Carlton, Indooropilly, North Adelaide or Subiaco – resisted large-scale development projects for freeways, ‘slum clearance’ and mass-produced high-rise. Unlikely alliances of post-war migrants, university students and staff, construction workers and their unions, long-term residents and city workers,challenged land-grabs and inappropriate development.When the dust settled, Australian cities were different. Many suburbs kept their village qualities. Shopping strips were revived and cultures celebrated. While areas like Fitzroy or Redcliff were derided as ‘Trendyville’, the fate many American cities suffered – a ‘hollow core’ – had been avoided. In the process, heritage conservation, party politics, and Australian assumptions about domestic life, education and lifestyle had all been transformed. This book is an in-depth examination of the causes and consequences of urban protest in a democracy. It shows how it changed the built environment as well as its participants, and resonated in many of our institutions including politics, media and multiculturalism.

Rapidly urbanising coastal locations represent prototypes of future cities. While these "sea change" locations will face a range of issues associated with rapid growth such as infrastructure provision and enhancement of social capital, anticipated environmental impacts are likely to add significant challenges. Climate change is likely to have dramatic impacts on sea change communities through diminished potable water supplies, rising sea levels, storm surges, and increased intensity of flood events - with indirect impacts on health, financial sectors, and biodiversity. Given the inherent diversity within sea change communities with regard to age, culture, and socio-economic status there are likely to be differences in ways of adapting, the ability to adapt, and the desired direction of any changes. Cognizant of the potential enormity of climate change impacts, the need for rapid responses, and the diversity within communities, this paper proposes a participatory and transformative method to work with communities in responding to climate change and variability within rapidly urbanising coastal locations. The method focuses on determining probable futures for various communities of place and interest within sea change areas and aims to build the capacity for dynamic on-going learning to achieve those futures, both within and between the communities. Through this process community members may be empowered with dynamic and future-orientated learning skills that build upon community knowledge, innovation, and resilience.

Myanmar is opening up to the world after fifty years of military rule and heading into times of rapid economic, social, and political transformation. There is some indication that the changes taking place in Myanmar will parallel those faced in Vietnam twenty-five years ago when it, too, emerged from a period of isolation and opened up to global investment, tourism, and intellectual influences. One of the similarities is likely to be in the growing awareness and use of cultural heritage as a political, economic, and social asset. In all states, capital cities are pivotal in the transformative processes and governments make use of heritage as part of nation-building strategies. This chapter opens up consideration of the role of heritage in times of rapid transformation in Yangon and Hanoi – respectively the colonial and post-colonial capitals of Myanmar (until November 2005) and Vietnam. Important cultural and political differences between the two national contexts are noted and questions asked about what Yangon might learn from the Vietnamese transformation experience.

In order to explore the long-run equilibrium in the house prices of different cities, studies on house price convergence have been conducted by a number of researchers. However, the majority of previous studies have neglected the effects of spatial heterogeneity and autocorrelation on house prices. This research improves on the investigation of house price convergence by developing a spatio-temporal autoregressive model based on a framework of panel regression methods. Both spatial heterogeneity and autocorrelation of house prices in different cities are taken into account. Geographical distance and the scale of development of the urban housing market are used to construct temporal varying spatial measurements. The spatio-temporal model is then applied to investigate the long-run equilibrium in the house prices of Australian capital cities. The results confirm that house prices in Sydney approach a steady state in the long run, whereas house prices in Brisbane, Canberra, Melbourne and Perth are able to do with lower confidence. However, little evidence supports the existence of long-run equilibrium in the house prices of Adelaide, Darwin and Hobart.

Drawing on decennial population statistics from 1881 to 1933, this article evaluates the settlement patterns of Scottish migrants in Australian cities. It considers the urban nature of Scottish settlement, and argues that settlement patterns were associated with employment opportunities for working-class Scots, along with various housing, lifestyle, and religious preferences, often grounded in pre-migration experiences of city living. Furthermore, this article demonstrates that Scottish migrants in Australia at the turn of the twentieth century largely belonged to an urban industrial working class, and provides a useful correction to the traditional images of Scots in Australia as mostly rural, well-off, and conservative migrants.

Religion and Urbanism contributes to an expanded understanding of 'sustainable cities' in South Asia by demonstrating the multiple, and often conflicting ways in which religion enables or challenges socially equitable and ecologically sustainable urbanisation in the region. In particular, this collection focuses on two aspects that must inform the sustainable cities discourse in South Asia: the intersections of religion and urban heritage, and religion and various aspects of informality.

This book makes a much-needed contribution to the nexus between religion and urban planning for researchers, postgraduate students and policy makers in Sustainable Development, Development Studies, Urban Studies, Religious Studies, Asian Studies, Heritage Studies and Urban and Religious Geography.

This paper reports on a comparative study that evaluates two approaches to support the learning and use of algorithmic design in architecture, and extrapolates from this to consider applications for the algorithmic design of cities. The study explored two methods to reduce the barriers of using programming and potentially improve design performance. The first is the reuse of abstract algorithmic ‘patterns’. The second approach is the reuse of algorithmic solutions from specific design cases (case-based design). Reflecting on this research we outline how our findings discussed in relation to alternate thinking on the use of pattern, might inform a hybrid approach to the algorithmic design of cities.
