“Right to the City” and the Structure of Civic Organizational Fields: Evidence from Cape Town

Publication ID: pub.1100656395

Publication date: 25/01/2018

Keywords: Cape Town; Civic Organizational Fields; Collective Action Frames; Inter-organizational Alliances; Right to the City; South Africa; Urban Environment

This article proposes a network analytic approach to the role of frames in shaping the structure of civic organizational fields. Adopting a perspective from the global South, it looks at the impact of the expression “Right to the city” (RTC) over alliance building among civil society actors, exploring patterns of collaborative ties among 129 civil […]

Emergent constraint on equilibrium climate sensitivity from global temperature variability

Publication ID: pub.1100426955

Publication date: 18/01/2018

Keywords: Carbon Dioxide; Global; Global Warming; History, 19th Century; History, 20th Century; History, 21st Century; Models, Theoretical; Observation; Probability; Temperature

Equilibrium climate sensitivity—which remains the largest uncertainty in climate projections—is constrained to a ‘likely’ range of 2.2–3.4 K by taking into account the variability of global temperature about long-term historical warming.

Human Agency in Disaster Planning: A Systems Approach

Publication ID: pub.1100432006

Publication date: 16/01/2018

Keywords: Human Factors; Soft Systems; Systems Modeling; Thames Valley; UK

Current approaches to risk management place insufficient emphasis on the system knowledge available to the assessor, particularly in respect of the dynamic behavior of the system under threat, the role of human agents (HAs), and the knowledge available to those agents. In this article, we address the second of these issues. We are concerned with […]

Exposure to and colonisation by antibiotic-resistant E. coli in UK coastal water users: Environmental surveillance, exposure assessment, and epidemiological study (Beach Bum Survey)

Publication ID: pub.1100404783

Publication date: 14/01/2018

Keywords: Bathing Beaches; Cross-Sectional Studies; Drug Resistance, Bacterial; England; Environmental Exposure; Environmental Monitoring; Escherichia coli; Humans; Swimming; United Kingdom; Wales

BACKGROUND: Antibiotic-resistant bacteria (ARB) present a global public health problem. With numbers of community-acquired resistant infections increasing, understanding the mechanisms by which people are exposed to and colonised by ARB can help inform effective strategies to prevent their spread. The role natural environments play in this is poorly understood. This is the first study to […]

Abrupt transitions in time series with uncertainties

Publication ID: pub.1100117421

Publication date: 03/01/2018

Keywords: Abrupt Transitions; Asian Summer Monsoon; Detect; El Niño-Southern Oscillation; Global; Global Stock Indices; Holocene; North Atlantic; Pacific Decadal Oscillation; Time Series Uncertainties

Identifying abrupt transitions is a key question in various disciplines. Existing transition detection methods, however, do not rigorously account for time series uncertainties, often neglecting them altogether or assuming them to be independent and qualitatively similar. Here, we introduce a novel approach suited to handle uncertainties by representing the time series as a time-ordered sequence […]

Morphology of travel routes and the organization of cities

Publication ID: pub.1099717869

Publication date: 20/12/2017

Keywords: Accessibility; Cities; Congestion; Diversity of Road Hierarchies; Functional Usage; Geometric Measure; Global; Inness Patterns; Morphology; Movement; Organization; Physical Connectivity; Street Structure; Travel Demand; Travel Routes; Urban Development; Urban Street Networks;

The city is a complex system that evolves through its inherent social and economic interactions. Mediating the movements of people and resources, urban street networks offer a spatial footprint of these activities. Of particular interest is the interplay between street structure and its functional usage. Here, we study the shape of 472,040 spatiotemporally optimized travel […]
