Sleep and dietary habits in the urban environment: the role of chrono-nutrition
The urban environment has changed vastly over past decades, which also has had an impact on our sleep and dietary patterns and possibly health outcomes. Some studies have shown that sleep duration and sleep quality has declined over past decades, especially in children. In parallel, our lifestyle and dietary patterns have also changed including more shift work, more meals outside the home or family setting and more irregular eating patterns, including breakfast skipping and late-night eating. This new area of research in nutritional sciences studying the impact of the timing of eating on health outcomes is called chrono-nutrition, and combines elements from nutritional research with chrono-biology. The objectives of this paper were to discuss secular trends in sleep patterns and related dietary patterns, introduce basic concepts and mechanisms of chrono-nutrition and discuss the evidence for the importance of sleep and chrono-nutrition in relation to health outcomes. Overall, chrono-nutrition could mediate the effects between sleep, diet and urbanisation, and more research is needed to elucidate the importance of chrono-nutrition for metabolic health and its impact on public health.

A year in the life of a third space urban teacher residency : using inquiry to reinvent teacher education
\"This book weaves together voices of faculty, residents, mentors, administrators, community organizers, and students who have lived together in a third space urban teacher residency program in Newark as they reinvent math and science teaching and teacher education through the lens of inquiry. Each chapter includes narratives from multiple perspectives as well as tools we have used within the program to support and build change, providing readers with both real cases of how an urban teacher residency can impact school systems, and concrete tools and examples to help the reader understand and replicate aspects of the process. Capturing both the successes but also the tensions and challenges, we offer a kaleidoscopic view of the rich, complex, and multi-layered ways in which multiple stakeholders work together to make enduring educational change in urban schools. Our third space NMUTR has been a fragile utopian enterprise, one that has relied on a shared commitment of all involved, and a deep sense of hope that working collaboratively has the potential, even if not perfect, to make a difference.\"--Publisher's website.

Risky Cities
Over half the world’s population lives in urban regions, and increasingly disasters are of great concern to city dwellers, policymakers, and builders. However, disaster risk is also of great interest to corporations, financiers, and investors. Risky Cities is a critical examination of global urban development, capitalism, and its relationship with environmental hazards. It is about how cities live and profit from the threat of sinkholes, garbage, and fire. Risky Cities is not simply about post-catastrophe profiteering. This book focuses on the way in which disaster capitalism has figured out ways to commodify environmental bads and manage risks. Notably, capitalist city-building results in the physical transformation of nature. This necessitates risk management strategies –such as insurance, environmental assessments, and technocratic mitigation plans. As such capitalists redistribute risk relying on short-term fixes to disaster risk rather than address long-term vulnerabilities.

How Do Urban Environments Affect Young People’s Mental Health? A Novel Conceptual Framework to Bridge Public Health, Planning, and Neurourbanism
Childhood and adolescence are crucial periods for mental and social development. Currently, mental illness among young people is a global epidemic, and rates of disorders such as depression and anxiety are rising. Urban living, compared with rural living, is linked with a higher risk of serious mental illness, which is important because the world is urbanizing faster than ever before. Urban environments and their landscapes, designs, and features influence mental health and well-being. However, no conceptual frameworks to date have detailed the effect of urban environments on young people’s mental health, and few studies have considered the growing role of digital and social media in this relationship, leading to calls for the development of holistic approaches to describe this relationship. This article synthesizes existing knowledge on urban places (both built and natural environments) and mental health in the public health and urban planning literature and examines the emerging field of neurourbanism (a multidisciplinary study of the effect of urban environments on mental health and brain activity) to enhance current practice and research. We developed 2 novel conceptual frameworks (1 research-oriented, 1 practice-oriented), adapted from Bronfenbrenner’s socioecological model, that focus on the relationship between urban environments and young people’s mental health. We added a digital and social media contextual level to the socioecological model, and we applied a multilayer concept to highlight potential cross-field interactions and collaborations. The proposed frameworks can help to guide future practice and research in this area.

The Sensory Experiencing of Urban Design
Experience is conceptualised in both academic and policy circles as a more-or-less direct effect of the design of the built environment. Drawing on findings from a research project that investigated people’s everyday experiences of designed urban environments in two UK towns, this paper suggests at least two reasons why sensory encounters between individuals and built environments cannot in fact be understood entirely as a consequence of the design features of those environments. Drawing from empirical analysis based on surveys, ethnographic ‘walk-alongs’ and photo-elicitation interviews, we argue that distinct senses of place do depend on the sensory experiencing of built environments. However, that experiencing is significantly mediated in two ways. First, it is mediated by bodily mobility: in particular, the walking practices specific to a particular built environment. Secondly, sensory experiences are intimately intertwined with perceptual memories that mediate the present moment of experience in various ways: by multiplying, judging and dulling the sensory encounter. In conclusion, it is argued that work on sensory urban experiencing needs to address more fully the diversity and paradoxes produced by different forms of mobility through, and perceptual memories of, built environments.

Hyperspectral and Lidar Data Applied to the Urban Land Cover Machine Learning and Neural-Network-Based Classification: A Review
Rapid technological advances in airborne hyperspectral and lidar systems paved the way for using machine learning algorithms to map urban environments. Both hyperspectral and lidar systems can discriminate among many significant urban structures and materials properties, which are not recognizable by applying conventional RGB cameras. In most recent years, the fusion of hyperspectral and lidar sensors has overcome challenges related to the limits of active and passive remote sensing systems, providing promising results in urban land cover classification. This paper presents principles and key features for airborne hyperspectral imaging, lidar, and the fusion of those, as well as applications of these for urban land cover classification. In addition, machine learning and deep learning classification algorithms suitable for classifying individual urban classes such as buildings, vegetation, and roads have been reviewed, focusing on extracted features critical for classification of urban surfaces, transferability, dimensionality, and computational expense.

Understanding urbanicity: how interdisciplinary methods help to unravel the effects of the city on mental health
Twenty-first century urbanization poses increasing challenges for mental health. Epidemiological studies have shown that mental health problems often accumulate in urban areas, compared to rural areas, and suggested possible underlying causes associated with the social and physical urban environments. Emerging work indicates complex urban effects that depend on many individual and contextual factors at the neighbourhood and country level and novel experimental work is starting to dissect potential underlying mechanisms. This review summarizes findings from epidemiology and population-based studies, neuroscience, experimental and experience-based research and illustrates how a combined approach can move the field towards an increased understanding of the urbanicity-mental health nexus.

Influence of Urbanization on Body Size, Condition, and Physiology in an Urban Exploiter: A Multi-Component Approach
Consistent expanding urbanization dramatically transforms natural habitats and exposes organisms to novel environmental challenges, often leading to reduced species richness and diversity in cities. However, it remains unclear how individuals are affected by the urban environment and how they can or cannot adjust to the specific characteristics of urban life (e.g. food availability). In this study, we used an integrative multi-component approach to investigate the effects of urbanization on the nutritional status of house sparrows (Passer domesticus). We assessed several morphological and physiological indices of body condition in both juveniles (early post-fledging) and breeding adults from four sites with different levels of urbanization in France, Western Europe. We found that sparrows in more urbanized habitats have reduced body size and body mass compared to their rural conspecifics. However, we did not find any consistent differences in a number of complementary indices of condition (scaled mass index, muscle score, hematocrit, baseline and stress-induced corticosterone levels) between urban and rural birds, indicating that urban sparrows may not be suffering nutritional stress. Our results suggest that the urban environment is unlikely to energetically constrain adult sparrows, although other urban-related variables may constrain them. On the other hand, we found significant difference in juvenile fat scores, suggesting that food types provided to young sparrows differed highly between habitats. In addition to the observed smaller size of urban sparrows, these results suggest that the urban environment is inadequate to satisfy early-life sparrows' nutritional requirements, growth, and development. The urban environment may therefore have life-long consequences for developing birds.
