Contestation and possibilities: Experiences in the 'other' urban classrooms

NASA Astrophysics Data System (ADS)

Grimes, Nicole K.

The research presented in this dissertation is a response to the general lack of research conducted in independent urban schools. In my work, I present varied vignettes that aim to provide a glimpse into the lifeworlds of students within such schools and how they too struggle to learn science. There are two major goals of this study. First, I encourage readers to rethink current conceptions of urban schooling and redefine what it means to be an urban learner. Secondly, I intend to demonstrate how the cogenerated action plans of coteachers and cogenerative dialogue groups can serve to make science accessible to students whom are diagnosed and placed in mainstreamed educational settings. The idea is to show that by transforming science learning contexts into cosmopolitan learning communities, students can become successful in science. Through a three-year ethnographic study of middle science classrooms in an independent school in New York City, I present explorations of the culture and context of the independent urban classroom as a chief means to meet my stated goals. By utilizing cogenerative dialogues and coteaching, I show how students and teachers can work together as co-researchers and coteachers that engage in a dual process of creating structures that support science success.

Transactional Sex Risk across a Typology of Rural and Urban Female Sex Workers in Indonesia: A Mixed Methods Study

2012-01-01

Context-specific typologies of female sex workers (FSWs) are essential for the design of HIV intervention programming. This study develops a novel FSW typology for the analysis of transactional sex risk in rural and urban settings in Indonesia. Mixed methods include a survey of rural and urban FSWs (n = 310), in-depth interviews (n = 11), key informant interviews (n = 5) and ethnographic assessments. Thematic analysis categorises FSWs into 5 distinct groups based on geographical location of their sex work settings, place of solicitation, and whether sex work is their primary occupation. Multiple regression analysis shows that the likelihood of consistent condom use was higher among urban venue-based FSWs for whom sex work is not the only source of income than for any of the other rural and urban FSW groups. This effect was explained by the significantly lower likelihood of consistent condom use by rural venue-based FSWs (adjusted OR: 0.34 95% CI 0.13–0.90, p = 0.029). The FSW typology and differences in organisational features and social dynamics are more closely related to the risk of unprotected transactional sex, than levels of condom awareness and availability. Interventions need context-specific strategies to reach the different FSWs identified by this study's typology. PMID:23285205

Community service contracting for older people in urban China: a case study in Guangdong Province.

PubMed

Lin, Wenyi

2016-01-01

Contracting of community services to non-governmental service-providing organisations - mainly social work agencies - is an emerging phenomenon and a social innovation with regard to delivering community services in urban China. Contracting of community services for the older person, which is the focus of this study, is embedded in the macro context of the development of social service contracting in China. Qualitative research techniques, including document analysis, case study, participant observation and in-depth interviews, were adopted for this study. Nine government officials, three staff working in Community Residents' Committees, 15 staff working in social work agencies and 41 older people were interviewed in an effort to understand the impact and challenges of community service contracting in urban China. The findings showed that the involvement of social work agencies in the community service provision system results in integration of community resources, expansion of service coverage and enhancement of older people's access to community services. However, several problems may impede the development of community service provision in the context of contracting in China. These include purchaser-oriented rather than user-oriented service provision, older people's negative attitude towards social work services, inappropriate performance measurement, reliance of non-government organisations on government funding and ambiguous definition of community services.

Race, urban context, and Russian roulette: findings from the National Violent Death Reporting System, 2003-2006.

PubMed

Wasserman, Ira; Stack, Steven

2011-02-01

Previous work on Russian roulette has focused on data from large cities. It is unclear if the epidemiological patterns based on large cities will replicate for the nation as a whole, and if the influence of minority status will be moderated by urban context. The present investigation fills these gaps by providing descriptive epidemiological data on Russian roulette for 17 states, and testing a hypothesis on urbanism as a moderator of the race-Russian roulette relationship. Data were taken from the National Violent Death Reporting System (2003-2006). They refer to 71 Russian roulette cases and a matched control group of 284 males who committed suicide by a gunshot wound to the head. Russian roulette suicides were more apt to be of minority status, younger, had a lower incidence of mental health problems, and were more likely to be utilizing alcohol than the controls. Differentiating the sample into larger and smaller urban areas, it was found that the risk of Russian roulette for African Americans was higher in larger urban areas. Epidemiological patterns in previous research on large city samples are largely replicated. The moderating influence of urban context is related to differential opportunity structures for risk-taking behavior. © 2011 The American Association of Suicidology.

Health impact assessment on urban development projects in France: finding pathways to fit practice to context.

PubMed

Roué-Le Gall, Anne; Jabot, Françoise

2017-06-01

In France, there is increasing interest in health impact assessments (HIAs) and most are performed on urban projects. The field of expertise is still under development and mostly established within the public health sector. To date, in France, all HIAs conducted in urban planning are stand-alone HIAs disconnected from the required environmental impact assessment (EIA). The paper opens with an introduction of the close and complex relationship between health and urban planning, HIA and a description of key elements needed for understanding the French context. Then, the paper analyses the context and the implementation process for four HIAs in progress in order to understand the specific characteristics of urban development, identify the key stages for introducing a health perspective into urban projects, and extract avenues to be explored when adapting HIAs applied to urban planning in France. Using a qualitative multiple case study design, an analysis framework was built to compare several aspects of the four HIAs and made it possible to highlight three pathways for adapting HIA to the urban planning sector: the schedule, links between the EIA and HIA, and the complementarity of the initiatives to involve residents. Legal measures enable a point of contact that brings health institutions and cities closer together. HIA is yet another tool that public authorities now have at their fingertips to work together in strengthening democracy and in reducing social, geographical and environmental health inequalities. More research must be undertaken to develop an understanding of the practice-related context; to judge HIA's capacity to draw on existing approaches in different fields; and to explore the different avenues leading to increased health, wellbeing and equity.

Advancing Community–Based Research with Urban American Indian Populations: Multidisciplinary Perspectives

Hartmann, William E.; Wendt, Dennis C.; Saftner, Melissa A.; Marcus, John; Momper, Sandra L.

2014-01-01

The U.S. has witnessed significant growth among urban AI populations in recent decades, and concerns have been raised that these populations face equal or greater degrees of disadvantage than their reservation counterparts. Surprisingly little urban AI research or community work has been documented in the literature, and even less has been written about the influences of urban settings on community-based work with these populations. Given the deep commitments of community psychology to empowering disadvantaged groups and understanding the impact of contextual factors on the lives of individuals and groups, community psychologists are well suited to fill these gaps in the literature. Toward informing such efforts, this work offers multidisciplinary insights from distinct idiographic accounts of community-based behavioral health research with urban AI populations. Accounts are offered by three researchers and one urban AI community organization staff member, and particular attention is given to issues of community heterogeneity, geography, membership, and collaboration. Each first-person account provides “lessons learned” from the urban context in which the research occurred. Together, these accounts suggest several important areas of consideration in research with urban AIs, some of which also seem relevant to reservation-based work. Finally, the potential role of research as a tool of empowerment for urban AI populations is emphasized, suggesting future research attend to the intersections of identity, sense of community, and empowerment in urban AI populations.

Characteristics of the Residential Neighborhood Environment Differentiate Intimate Partner Femicide in Urban Versus Rural Settings

Beyer, Kirsten M. M.; Layde, Peter M.; Hamberger, L. Kevin; Laud, Purushottam W.

2012-01-01

Purpose A growing body of work examines the association between neighborhood environment and intimate partner violence (IPV). As in the larger literature examining the influence of place context on health, rural settings are understudied and urban and rural residential environments are rarely compared. In addition, despite increased attention to the linkages between neighborhood environment and IPV, few studies have examined the influence of neighborhood context on intimate partner femicide (IPF). In this paper, we examine the role for neighborhood-level factors in differentiating urban and rural IPFs in Wisconsin, USA. Methods We use a combination of Wisconsin Violent Death Reporting System (WVDRS) data and Wisconsin Coalition Against Domestic Violence (WCADV) reports from 2004–2008, in concert with neighborhood-level information from the US Census Bureau and US Department of Agriculture, to compare urban and rural IPFs. Findings Rates of IPF vary based on degree of rurality, and bivariate analyses show differences between urban and rural victims in race/ethnicity, marital status, country of birth, and neighborhood characteristics. After controlling for individual characteristics, the nature of the residential neighborhood environment significantly differentiates urban and rural IPFs. Conclusions Our findings suggest a different role for neighborhood context in affecting intimate violence risk in rural settings, and that different measures may be needed to capture the qualities of rural environments that affect intimate violence risk. Our findings reinforce the argument that multilevel strategies are required to understand and reduce the burden of intimate violence, and that interventions may need to be crafted for specific geographical contexts.

2010-07-01

Developing country urban contexts present multiple challenges to those responsible for ensuring the good health of urban populations. These include urban growth, migration, informal settlements, intra-urban inequalities and - in some cases - high HIV prevalence. Using Johannesburg as a case study, this paper explores the complexities of the urban context by comparing the social determinants of urban health between migrant groups residing in the inner-city and a peripheral urban informal settlement. It is argued that any attempt to improve the health of urban populations in the context of migration and HIV requires understanding that 'place matters'. 2010 Elsevier Ltd. All rights reserved.

"It's Kind of a Dichotomy": Thoughts Related to Calling and Purpose from Pastors Working and Counseling in Urban Resource-Poor Communities.

PubMed

Payne, Jennifer Shepard

2017-08-01

Pastors serving low-income urban areas are first-responders to emotional issues by default, since fewer mental health resources are available. Thus, it is important to understand how pastors serving urban resource-poor areas reflect on their counseling role. Forty-eight Black, Hispanic, and White pastors with urban congregations in Los Angeles or Chicago reflect on their pastoral calling and its relation to their counseling role. Through phenomenology, the pastors' lived experiences as they counseled in an urban context were explored. Analysis revealed complex feelings about their counseling role in light of their resource-poor environments. Recommendations are provided based on the findings.

Urban mosquitoes, situational publics, and the pursuit of interspecies separation in Dar es Salaam

PubMed Central

KELLY, ANN H.; LEZAUN, JAVIER

2014-01-01

Recent work in anthropology points to the recognition of multispecies entanglements as the grounds for a more ethical politics. In this article, we examine efforts to control mosquitoes in Dar es Salaam, Tanzania, as an example of the laborious tasks of disentanglement that characterize public health interventions. The mosquito surveillance and larval elimination practices of an urban malaria control program offer an opportunity to observe how efforts to create distance between species relate to the physical and civic textures of the city. Seen in the particular context of the contemporary African metropolis, the work of public health appears less a matter of control than a commitment to constant urban maintenance and political mobilization.

Achievement of a coherent and strong sense of self is critical to positive academic outcomes for urban minority youth. The present study utilized a mixed-methods approach to explore key aspects of identity development for African American adolescents living in a high-poverty, urban neighborhood. Results suggest that efforts to develop a sense of oneself as an individual and in relation to the world are impeded by mixed messages on African American culture and achievement. Findings are discussed in the context of teaching and working with urban African American adolescents in a way that promotes positive identity development.

Thinking about gender, thinking about a common space of observation and discussion of the work activity of the other: the case of bus drivers.

PubMed

Cunha, Liliana; Nogueira, Sónia; Lacomblez, Marianne

2012-01-01

The work activity of urban bus drivers is held in the public space and characterized by a constant vigilance, but the moments of observation the colleagues' work are scarce. This fact results in a paradox--it is a work activity that is more visible to "outsiders" than to "insiders"--which has an important impact on the debate of the work activity from a perspective of gender and the women's work in a predominantly male context. Ergonomic analysis of work and semi-structured interviews were conducted with 32 urban public transport drivers, 16 women and 16 men. The results reveal the lack of conditions for the drivers' knowledge of the activity of another, especially when that other is a woman--while men attribute characteristics to women based on gender stereotypes and an extension of their role in the private sphere, women relate them with the need to prove their competence and be recognized. It is proposed the development, in the context of training, of a space for debate and knowledge of the activity of the other and for the creation of conditions for another integration of women in the profession and for another visibility of their work.

Evaluation des apports solaires a l'echelle d'un quartier urbain en periode de chauffe selon sa typologie, son orientation et sa latitude dans un contexte de densification de la ville

NASA Astrophysics Data System (ADS)

Chenard, Laurent

Mass urbanization is a major issue for town administrators. Population increase will have an impact on the quality of the environment for citizens. Government will have to take decisions to limit those effects. Green energies are part of the solution to reach fixed goals by the public administration for sustainable development. Passive solar energy is studied in this work in an urban canopy located in five different towns: San Francisco, Montreal, Bordeaux, Lyon and Stockholm. Passive solar energy is calculated in the heating season. Direct and diffuse solar radiation is considered by using the Perez model. Radiosity is not taken into account. Heating demand is calculated by the heating degree day method. Seven urban forms have been created to determine the amount of solar energy entering in every window of the urban canopy while taking into account urban context and forms. Optimal orientation of the canopy shows an increase of 5% of the passive solar radiation from original orientation, 180 degrees rotation from first orientation straight south. This value goes lower when stories are added to the urban context. A rotation of 90 degrees from the first orientation shows a decrease of 6 to 15% in solar passive gain. Densification of the urban canopy by adding stories to the buildings results in a loss up to 65% of the solar gain for the first story. It is showed that solar passive energy has a low ratio of 5% for space heating for old buildings, 1960 constructions. Today's buildings have a difference between passive solar energy and heating demand of 10 to 75% depending on the model and location.

Modeling and formal analysis of urban road traffic

2013-10-01

Modern life in cities leads to complex urban traffic road and, sometimes, to go from one point to another, in a city, is a hard and very complex task. The use of assisted systems for helping drivers on their task of reaching the desired destination is being common, mainly systems like GPS location systems or other similar systems. The main gap of those systems is that they are not able to assist drivers when some unexpected changes occur, like accidents, or another unexpected situations. In this context, it would be desirable to have a dynamic system to inform the drivers, about everything that is happening "online". This work is inserted in this context and the work presented here is one part of a bigger project that has, as main goal, to be a dynamic system for assisting drivers under hard conditions of urban road traffic. In this paper is modeled, and formally analyzed, the intersection of four street segments, in order to take some considerations about this subject. This paper presents the model of the considered system, using timed automata formalism. The validation and verification of the road traffic model it is realized using UPPAAL model-checker.

A multidisciplinary approach of the problem of noise nuisance in urban environment

NASA Astrophysics Data System (ADS)

Rabah, Derbal Cobis; Hamza, Zeghlache

2002-05-01

More often the problem of noise and sonic pollution, particularly in urban sites, is studied by different disciplines such as physics, the acoustics, the psychoacoustics, the medicine and others. It is independently of each other that these sciences are often approaching this subject. Some studies are carried out in laboratories taking noise as samples cut off their realistic context. Urban noise is studied as well by making an abstraction of the different contextual parameters by idealizing a rather complex sonic environment. The noise, according to this present approach, is suposed to react with surounding space, and it takes the form and the quality of the place by defining and requalifying it. It is found that the contextual aspects such as social, cultural or even symbolic dimensions modulate the listening conditions and the perception quality of the noise and even the living and the daily practice of the urban space. The multiparameter dimension study of the noise in an urban context is necessary to better work out the problem and to try to come up with some practical and efficient solutions. The little amount of studies based on such multidisciplinary approach, confort well our effort to go ahead with this methodological approach.

Urban terrain reconstruction has many applications in areas of civil engineering, urban planning, surveillance and defense research. Therefore the needs of covering ad-hoc demand and performing a close-range urban terrain reconstruction with miniaturized and relatively inexpensive sensor platforms are constantly growing. Using (miniaturized) unmanned aerial vehicles, (M)UAVs, represents one of the most attractive alternatives to conventional large-scale aerial imagery. We cover in this paper a four-step procedure of obtaining georeferenced 3D urban models from video sequences. The four steps of the procedure - orientation, dense reconstruction, urban terrain modeling and geo-referencing - are robust, straight-forward, and nearly fully-automatic. The two last steps - namely, urban terrain modeling from almost-nadir videos and co-registration of models 6ndash; represent the main contribution of this work and will therefore be covered with more detail. The essential substeps of the third step include digital terrain model (DTM) extraction, segregation of buildings from vegetation, as well as instantiation of building and tree models. The last step is subdivided into quasi- intrasensorial registration of Euclidean reconstructions and intersensorial registration with a geo-referenced orthophoto. Finally, we present reconstruction results from a real data-set and outline ideas for future work.

Characterizing Urban Household Waste Generation and Metabolism Considering Community Stratification in a Rapid Urbanizing Area of China.

2015-01-01

The relationship between social stratification and municipal solid waste generation remains uncertain under current rapid urbanization. Based on a multi-object spatial sampling technique, we selected 191 households in a rapidly urbanizing area of Xiamen, China. The selected communities were classified into three types: work-unit, transitional, and commercial communities in the context of housing policy reform in China. Field survey data were used to characterize household waste generation patterns considering community stratification. Our results revealed a disparity in waste generation profiles among different households. The three community types differed with respect to family income, living area, religious affiliation, and homeowner occupation. Income, family structure, and lifestyle caused significant differences in waste generation among work-unit, transitional, and commercial communities, respectively. Urban waste generation patterns are expected to evolve due to accelerating urbanization and associated community transition. A multi-scale integrated analysis of societal and ecosystem metabolism approach was applied to waste metabolism linking it to particular socioeconomic conditions that influence material flows and their evolution. Waste metabolism, both pace and density, was highest for family structure driven patterns, followed by lifestyle and income driven. The results will guide community-specific management policies in rapidly urbanizing areas.

The Downside of Marketization: A Multilevel Analysis of Housing Tenure and Types in Reform-era Urban China

PubMed Central

Fu, Qiang; Zhu, Yushu; Ren, Qiang

2015-01-01

Based on data from the 2005 National Population Sample Survey and compiled covariates of 205 prefectures, this research adopted principal-component and multilevel-logistic analyses to study homeownership in urban China. Although the housing reform has severed the link between work units and residence, working in state sectors (government, state-owned enterprises and collective firms) remained significant in determining a household’s entitlement to reform-era housing with heavy subsidies or better qualities. While the prefecture-level index of marketization reduced local homeownership of self-built housing, affordable housing and privatized housing, its effect is moderated by cross-level interactions with income, education and working in state sectors across different types of housing. Meanwhile, the index of political and market connections promoted all types of homeownership except for self-built housing. By situating the downside of marketization within a context of urban transformation, this research not only challenges the teleological premise of the neoliberal market transition theory but calls for research on institutional dynamics and social consequences of urban transformation in China.

The available sustainable building evaluation systems have produced a new environmental design paradigm. However, there is an increasing need to overcome the buildingcentric approach of these systems, in order to further exploit their innovate potential for sustainable building practices. The paper takes this challenge by developing a cross-scale evaluation approach focusing on the reliability of sustainable building design solutions for the context in which the building is situated. An integrated building-urban evaluation model is proposed based on the urban matrix, which is a conceptualisation of the built environment as a social-ecological system. The model aims at evaluating the sustainability ofmore » a building considering it as an active entity contributing to the resilience of the urban matrix. Few holistic performance indicators are used for evaluating such contribution, so expressing the building reliability. The discussion on the efficacy of the model shows that it works as a heuristic tool, supporting the acquisition of a better insight into the complexity which characterises the relationships between the building and the built environment sustainability. Shading new lights on the meaning of sustainable buildings, the model can play a positive role in innovating sustainable building design practices, thus complementing current evaluation systems. - Highlights: Black-Right-Pointing-Pointer We model an integrated building-urban evaluation approach.

Many attempt to address the documented achievement gap between urban and suburban students by offering special programs to enrich urban students' academic experiences and proficiencies. Such was the case in the study described by DeGennaro and Brown in which urban students participated in an after-school technology course intended to address the "digital divide" by giving these youth supported experiences as technology users. However, also like the initial situation described in this study, instructional design that does not capitalize on what we know about urban education or informal learning contexts can actually further damage urban youths' identities as learners by positioning them as powerless and passive recipients instead of meaningful contributors to their own learning. The analysis presented in this forum is intended to further the conversation begun by DeGennaro and Brown by explicitly complexifying our consideration of context (activity structures and setting) so as to support the development of contexts that afford rich learning potential for both the urban students and their learning facilitators, positioned in the role of teachers. Carefully constructed contexts can afford participants as learners (urban students and teachers) opportunities to access rich identity resources (not typically available in traditional school contexts) including, but not limited to, the opportunity to exercise agency that allows participants to reorganize their learning context and enacted culture as needed.

Hospitality, culture and regeneration: urban decay, entrepreneurship and the "ruin" bars of Budapest.

This paper considers the relationships between hospitality, culture and urban regeneration through an examination of rom (ruin) venues, which operate in dilapidated buildings in Budapest, Hungary. The paper reviews previous work on culture and urban regeneration in order to locate the role of hospitality within emerging debates. It subsequently interrogates the evolution of the rom phenomenon and demonstrates how, in this context, hospitality thrives because of social and physical decay in urban locations, how operators and entrepreneurs exploit conflicts among various actors involved in regeneration and how hospitality may be mobilised purposefully in the regeneration process. The paper demonstrates how networked entrepreneurship maintains these operations and how various forms of cultural production are entangled and mobilised in the venues' hospitality propositions.

Universal scaling of the distribution of land in urban areas

NASA Astrophysics Data System (ADS)

Riascos, A. P.

2017-09-01

In this work, we explore the spatial structure of built zones and green areas in diverse western cities by analyzing the probability distribution of areas and a coefficient that characterize their respective shapes. From the analysis of diverse datasets describing land lots in urban areas, we found that the distribution of built-up areas and natural zones in cities obey inverse power laws with a similar scaling for the cities explored. On the other hand, by studying the distribution of shapes of lots in urban regions, we are able to detect global differences in the spatial structure of the distribution of land. Our findings introduce information about spatial patterns that emerge in the structure of urban settlements; this knowledge is useful for the understanding of urban growth, to improve existing models of cities, in the context of sustainability, in studies about human mobility in urban areas, among other applications.

We need more empirical investigations and model validation for a better understanding of crime. Comment on "Statistical physics of crime: A review" by M.R. D'Orsogna and M. Perc

2015-03-01

Since the seminal works of Wilson and Kelling [1] in 1982, the "broken windows theory" seems to have been widely accepted among the criminologists and, in fact, empirical findings actually point out that criminals tend to return to previously visited locations. Crime has always been part of the urban society's agenda and has also attracted the attention of scholars from social sciences ever since. Furthermore, over the past six decades the world has experienced a quick and notorious urbanization process: by the eighties the urban population was about 40% of total population, and today more than half (54%) of the world population is urban [2]. The urbanization has brought us many benefits such as better working opportunities and health care, but has also created several problems such as pollution and a considerable rise in the criminal activities. In this context of urban problems, crime deserves a special attention because there is a huge necessity of empirical and mathematical (modeling) investigations which, apart from the natural academic interest, may find direct implications for the organization of our society by improving political decisions and resource allocation.

A survey of urban climate change experiments in 100 cities

Castán Broto, Vanesa; Bulkeley, Harriet

2013-01-01

Cities are key sites where climate change is being addressed. Previous research has largely overlooked the multiplicity of climate change responses emerging outside formal contexts of decision-making and led by actors other than municipal governments. Moreover, existing research has largely focused on case studies of climate change mitigation in developed economies. The objective of this paper is to uncover the heterogeneous mix of actors, settings, governance arrangements and technologies involved in the governance of climate change in cities in different parts of the world. The paper focuses on urban climate change governance as a process of experimentation. Climate change experiments are presented here as interventions to try out new ideas and methods in the context of future uncertainties. They serve to understand how interventions work in practice, in new contexts where they are thought of as innovative. To study experimentation, the paper presents evidence from the analysis of a database of 627 urban climate change experiments in a sample of 100 global cities. The analysis suggests that, since 2005, experimentation is a feature of urban responses to climate change across different world regions and multiple sectors. Although experimentation does not appear to be related to particular kinds of urban economic and social conditions, some of its core features are visible. For example, experimentation tends to focus on energy. Also, both social and technical forms of experimentation are visible, but technical experimentation is more common in urban infrastructure systems. While municipal governments have a critical role in climate change experimentation, they often act alongside other actors and in a variety of forms of partnership. These findings point at experimentation as a key tool to open up new political spaces for governing climate change in the city. PMID:23805029

2015-01-01

The relationship between social stratification and municipal solid waste generation remains uncertain under current rapid urbanization. Based on a multi-object spatial sampling technique, we selected 191 households in a rapidly urbanizing area of Xiamen, China. The selected communities were classified into three types: work-unit, transitional, and commercial communities in the context of housing policy reform in China. Field survey data were used to characterize household waste generation patterns considering community stratification. Our results revealed a disparity in waste generation profiles among different households. The three community types differed with respect to family income, living area, religious affiliation, and homeowner occupation. Income, family structure, and lifestyle caused significant differences in waste generation among work-unit, transitional, and commercial communities, respectively. Urban waste generation patterns are expected to evolve due to accelerating urbanization and associated community transition. A multi-scale integrated analysis of societal and ecosystem metabolism approach was applied to waste metabolism linking it to particular socioeconomic conditions that influence material flows and their evolution. Waste metabolism, both pace and density, was highest for family structure driven patterns, followed by lifestyle and income driven. The results will guide community-specific management policies in rapidly urbanizing areas. PMID:26690056

While social integration among individuals with psychosis differs by social context, this has rarely been investigated across urban vs. rural settings. For individuals with psychosis, marriage may be a key component of social integration. This study aims to compare marriage outcomes for individuals with psychosis in urban vs. rural settings in China, where marriage has been almost universal among individuals without psychosis. In a large community-based study in four provinces representing 12% of China's population, we identified 393 individuals with psychosis (112 never treated). We used adjusted Poisson regression models to compare marriage status for those living in urban (n = 96) vs. rural (n = 297) contexts. While urban and rural residents had similar impairments due to symptoms, urban female residents were 2.72 times more likely to be unmarried than their rural counterparts (95% CI 1.19-6.22, p < 0.0176). Stratified analyses indicated that this marital disadvantage occurred primarily among urban females with an earlier age of onset. No differences were found among males. Our findings indicate that urban contexts impeded opportunities for marriage for female individuals with psychosis. These data suggest that urban women with earlier age of onset have difficulty in marrying which may be related to economic expectations of women in urban areas. Research examining contextual mechanisms that affect marriage may further understanding of social integration in China and other contexts.

Near surface geophysics techniques and geomorphological approach to reconstruct the hazard cave map in historical and urban areas

NASA Astrophysics Data System (ADS)

Lazzari, M.; Loperte, A.; Perrone, A.

2010-03-01

This work, carried out with an integrated methodological approach, focuses on the use of near surface geophysics techniques, such as ground penetrating radar and electrical resistivity tomography (ERT), and geomorphological analysis, in order to reconstruct the cave distribution and geometry in a urban context and, in particular, in historical centres. The interaction during recent centuries between human activity (caves excavation, birth and growth of an urban area) and the characters of the natural environment were the reasons of a progressive increase in hazard and vulnerability levels of several sites. The reconstruction of a detailed cave map distribution is the first step to define the anthropic and geomorphological hazard in urban areas, fundamental basis for planning and assessing the risk.

The paper examines the role of community-based participatory research (CBPR) within the context of social justice literature and practice. Two CBPR case studies addressing health inequities related to Type 2 Diabetes and Cardiovascular disease were selected from a national cross-site study assessing effective academic-community research partnerships. One CBPR partnership works with African Americans in rural Pemiscot County, Missouri and the other CBPR partnership works with African American and Latinos in urban South Bronx, New York City. Data collection included semi-structured key informant interviews and focus groups. Analysis focused on partnerships' context/history and their use of multiple justice-oriented strategies to achieve systemic and policy changes in order to address social determinants of health in their communities. Community context and history shaped each partnership's strategies to address social determinants. Four social justice approaches (identity/recognition, procedural, distributive, and structural justice) used by both partnerships were identified. These social justice approaches were employed to address underlying causes of inequitable distribution of resources and power structures, while remaining within a scientific research framework. CBPR can bridge the role of science with civic engagement and political participation, empowering community members to become political agents who integrate evidence into their social justice organizing strategies.

Exploring the contexts of urban science classrooms: Cogenerative dialogues, coteaching, and cosmopolitanism

NASA Astrophysics Data System (ADS)

Emdin, Christopher

The body of work presented in this dissertation is a response to the reported association between poor outcomes in science achievement and students of color in urban schools. By presenting counterexamples to the cultural motif that urban students of color perform poorly in science, I argue that poor achievement cannot be traced to a group of people but can be linked to institutions promoting subject delivery methods that instill distaste for science and compel students to display an illusion of disinterest in school. There are two major goals of this study. First, I plan to demonstrate how plans of action generated by coteachers and cogenerative dialogue groups can coalesce under the ethos of making science and schooling accessible to populations that are traditionally marginalized from science achievement. My second aim is to develop mechanisms for transforming science learning contexts into cosmopolitan learning communities that develop student success in science. Through a three-year ethnographic study of physics and chemistry classrooms in a high school in New York City, I present explorations of the culture and context of the urban classroom as a chief means to meet my goals. In my research, I find that obstacles to identity development around science can be tied to corporate understandings of teaching and learning that are amenable to local efforts toward change. This change is facilitated through the use of transformative tools like cogenerative dialogues, coteaching, and cosmopolitanism. Through the application of these research tools, I uncover and investigate how various misalignments that present themselves in physics and chemistry classrooms serve as signifiers of macro issues that permeate science classrooms from larger fields. By utilizing cogenerative dialogues as a tool for investigating both micro enactments within classrooms and the macro structures that generate these enactments, I show how students and teachers can work together as co-researchers and coteachers that engage in a dual process of questioning existent structures that do not support science success and transforming them.

A Pattern-Based Definition of Urban Context Using Remote Sensing and GIS

2016-01-01

In Sub-Saharan Africa rapid urban growth combined with rising poverty is creating diverse urban environments, the nature of which are not adequately captured by a simple urban-rural dichotomy. This paper proposes an alternative classification scheme for urban mapping based on a gradient approach for the southern portion of the West African country of Ghana. Landsat Enhanced Thematic Mapper Plus (ETM+) and European Remote Sensing Satellite-2 (ERS-2) synthetic aperture radar (SAR) imagery are used to generate a pattern based definition of the urban context. Spectral mixture analysis (SMA) is used to classify a Landsat scene into Built, Vegetation and Other land covers. Landscape metrics are estimated for Built and Vegetation land covers for a 450 meter uniform grid covering the study area. A measure of texture is extracted from the SAR imagery and classified as Built/Non-built. SMA based measures of Built and Vegetation fragmentation are combined with SAR texture based Built/Non-built maps through a decision tree classifier to generate a nine class urban context map capturing the transition from unsettled land at one end of the gradient to the compact urban core at the other end. Training and testing of the decision tree classifier was done using very high spatial resolution reference imagery from Google Earth. An overall classification agreement of 77% was determined for the nine-class urban context map, with user’s accuracy (commission errors) being lower than producer’s accuracy (omission errors). Nine urban contexts were classified and then compared with data from the 2000 Census of Ghana. Results suggest that the urban classes appropriately differentiate areas along the urban gradient.

The construction of illness as an inscription on the body of colonization figures importantly among Indigenous community-based service and health care providers. While residential schools and diabetes have both been characterized as products of colonization, little work has been done to examine how they are connected to and informative for health provider practice. The research data presented in this article come from a collaborative urban Indigenous community-based study examining the legacy of negative relationships with food that was instilled in residential schools and used in diabetes intervention. I illustrate how residential school disciplined eating, providing a context for understanding the contemporary production of Indigenous health knowledge and practice in the urban setting, and the diet-related management of diabetes.

A Review of Current Investigations of Urban-Induced Rainfall and Recommendations for the Future

NASA Technical Reports Server (NTRS)

Shepherd, J. Marshall

2004-01-01

Precipitation is a key link in the global water cycle and a proxy for changing climate; therefore proper assessment of the urban environment s impact on precipitation (land use, aerosols, thermal properties) will be increasingly important in ongoing climate diagnostics and prediction, Global Water and Energy Cycle (GWEC) analysis and modeling, weather forecasting, freshwater resource management, urban planning-design and land-atmosphere-ocean interface processes. These facts are particularly critical if current projections for global urban growth are accurate. The goal of this paper is to provide a concise review of recent (1990-present) studies related to how the urban environment affects precipitation. In addition to providing a synopsis of current work, recent findings are placed in context with historical investigations such as METROMEX studies. Both observational and modeling studies of urban-induced rainfall are discussed. Additionally, a discussion of the relative roles of urban dynamic and microphysical (e.g. aerosol) processes is presented. The paper closes with a set of recommendations for what observations and capabilities are needed in the future to advance our understanding of the processes.

Work disability prevention in rural healthcare workers.

PubMed

Franche, Renée L; Murray, Eleanor J; Ostry, Aleck; Ratner, Pamela A; Wagner, Shannon L; Harder, Henry G

2010-01-01

Approximately 20% of healthcare workers in high-income countries such as Australia, Canada and the USA work in rural areas. Healthcare workers are known to be vulnerable to occupational injury and poor work disability outcomes; given their rural-urban distribution, it is possible to compare work disability prevention in rural and urban areas. However, little attention has been paid to work disability prevention issues specific to rural workers, including rural healthcare workers. A comprehensive review of the literature was conducted to identify rural-urban differences in work disability outcomes (defined as the incidence of occupational injury and the duration of associated work absence), as well as risk factors for poor work disability outcomes in rural healthcare workers. The databases MEDLINE, CINAHL, and EMBASE were searched, as were relevant research centers and government agencies, to identify all quantitative and qualitative English-language studies published between 1 January 2000 and 6 October 2009 that discussed occupational injury, work absence duration, work disability management, or risk factors for poor work disability outcomes, for rural workers specifically, or in comparison with urban workers. To ensure inclusion of studies of healthcare workers as a distinct group among other sector-specific groups, a broad search for literature related to all industrial sectors was conducted. Of 860 references identified, 5 discussed work disability outcomes and 25 discussed known risk factors. Known risk factors were defined as factors firmly established to be associated with poor work disability outcomes in the general worker population based on systematic reviews, well-established conceptual models of work disability prevention, and public health literature. Although somewhat conflicting, the evidence suggests that rural healthcare workers experience higher rates of occupational injury compared with urban healthcare workers, within occupational categories. Rural workers also appear to be more vulnerable to prolonged work absence although the data are limited. No studies directly compared risk factors for work disability prevention outcomes between rural and urban healthcare workers. However, potential risk factors were identified at the level of the environment, worker, job, organization, worker compensation system and healthcare access. Important methodological limitations were noted, including unclear definitions of rurality, inadequate methods of urban-rural comparisons such as comparing samples from different countries, and a paucity of studies applying longitudinal or multivariate designs. There is a notable lack of evidence about work disability prevention issues for healthcare workers in rural areas. Available evidence supports the hypothesis that rural healthcare workers are vulnerable to occupational injury, and suggests they are vulnerable to prolonged work absence. They may be particularly vulnerable to poor work disability prevention outcomes due to complex patient needs in the context of risk factors such as heavy workloads, long hours, heavy on-call demands, high stress levels, limited support and workplace violence. Additional vulnerability may occur because their work conditions are managed in distant urban administrative centers, and due to barriers in their own healthcare access. Although rural healthcare workers seem generally at greater risk of injury, one study suggests that urban emergency medical service workers experience a high vulnerability to injury that may outweigh the effects of rurality. Additional research is needed to document rural-urban disparities in work disability outcomes and to identify associated sources and risk factors. Other issues to address are access to and quality of healthcare for rural healthcare workers, streamlining the compensation system, the unique needs of Aboriginal healthcare workers, and the management of prolonged work absence. Finally, occupational injury and work absence duration programs should be tailored to meet the needs of rural workers.

Synthetic fibers in atmospheric fallout: A source of microplastics in the environment?

Sources, pathways and reservoirs of microplastics, plastic particles smaller than 5mm, remain poorly documented in an urban context. While some studies pointed out wastewater treatment plants as a potential pathway of microplastics, none have focused on the atmospheric compartment. In this work, the atmospheric fallout of microplastics was investigated in two different urban and sub-urban sites. Microplastics were collected continuously with a stainless steel funnel. Samples were then filtered and observed with a stereomicroscope. Fibers accounted for almost all the microplastics collected. An atmospheric fallout between 2 and 355 particles/m(2)/day was highlighted. Registered fluxes were systematically higher at the urban than at the sub-urban site. Chemical characterization allowed to estimate at 29% the proportion of these fibers being all synthetic (made with petrochemicals), or a mixture of natural and synthetic material. Extrapolation using weight and volume estimates of the collected fibers, allowed a rough estimation showing that between 3 and 10 tons of fibers are deposited by atmospheric fallout at the scale of the Parisian agglomeration every year (2500 km(2)). These results could serve the scientific community working on the different sources of microplastic in both continental and marine environments. Copyright © 2016 Elsevier Ltd. All rights reserved.

Knowledge Co-production at the Research-Practice Interface: Embedded Case Studies from Urban Forestry.

PubMed

Campbell, Lindsay K; Svendsen, Erika S; Roman, Lara A

2016-06-01

Cities are increasingly engaging in sustainability efforts and investment in green infrastructure, including large-scale urban tree planting campaigns. In this context, researchers and practitioners are working jointly to develop applicable knowledge for planning and managing the urban forest. This paper presents three case studies of knowledge co-production in the field of urban forestry in the United States. These cases were selected to span a range of geographic scales and topical scopes; all three are examples of urban researcher-practitioner networks in which the authors are situated to comment on reflexively. The three cases resemble institutional structures described in the knowledge co-production literature, including participatory research, a hybrid organization of scientists and managers, and a community of practice. We find that trust, embeddedness, new approaches by both practitioners and researchers, and blending of roles all serve to recognize multiple forms of capability, expertise, and ways of knowing. We discuss the impacts of knowledge co-production and the ways in which hybrid institutional forms can enable its occurrence.

The Consortium for Climate Risk in the Urban Northeast (CCRUN), one of ten NOAA-RISA's, supports resilience efforts in the urban corridor stretching from Philadelphia to Boston. Challenges and opportunities include the diverse set of needs in broad urban contexts, as well as the integration of interdisciplinary perspectives. CCRUN is addressing these challenges through 1) stakeholder surveys, 2) webinar series that enable scientists to engage with stakeholders, 3) leveraging extreme events as focusing opportunities, and 4) the development of an integrated project framework. Moving forward, increasing extreme events can lead to unexpected detours, and further effort is needed around facilitating place-based research in an interdisciplinary context.

Do cities simulate climate change? A comparison of herbivore response to urban and global warming.

2015-01-01

Cities experience elevated temperature, CO2 , and nitrogen deposition decades ahead of the global average, such that biological response to urbanization may predict response to future climate change. This hypothesis remains untested due to a lack of complementary urban and long-term observations. Here, we examine the response of an herbivore, the scale insect Melanaspis tenebricosa, to temperature in the context of an urban heat island, a series of historical temperature fluctuations, and recent climate warming. We survey M. tenebricosa on 55 urban street trees in Raleigh, NC, 342 herbarium specimens collected in the rural southeastern United States from 1895 to 2011, and at 20 rural forest sites represented by both modern (2013) and historical samples. We relate scale insect abundance to August temperatures and find that M. tenebricosa is most common in the hottest parts of the city, on historical specimens collected during warm time periods, and in present-day rural forests compared to the same sites when they were cooler. Scale insects reached their highest densities in the city, but abundance peaked at similar temperatures in urban and historical datasets and tracked temperature on a decadal scale. Although urban habitats are highly modified, species response to a key abiotic factor, temperature, was consistent across urban and rural-forest ecosystems. Cities may be an appropriate but underused system for developing and testing hypotheses about biological effects of climate change. Future work should test the applicability of this model to other groups of organisms. Published 2014. This article is a U.S. Government work and is in the public domain in the USA.

Background Although outcomes among people with schizophrenia differ by social context, this has rarely been examined across rural v. urban settings. For individuals with schizophrenia, employment is widely recognised as a critical ingredient of social integration. Aims To compare employment for people with schizophrenia in rural v. urban settings in China. Method In a large community-based study in four provinces representing 12% of China’s population, we identified 393 people with schizophrenia (112 never treated). We used adjusted Poisson regression models to compare employment for those living in rural (n = 297) v. urban (n = 96) settings. Results Although rural and urban residents had similar impairments due to symptoms, rural residents were three times more likely to be employed (adjusted relative risk 3.27, 95% CI 2.11–5.07, P<0.001). Conclusions People with schizophrenia have greater opportunities to use their capacities for productive work in rural than urban settings in China. Contextual mechanisms that may explain this result offer a useful focus for future research. PMID:23258768

Exploring the contexts of urban science classrooms. Part 2: The emergence of rituals in the learning of science

NASA Astrophysics Data System (ADS)

Emdin, Christopher

2007-04-01

In Part 1 of this paper, I described the corporate and communal nature of research, teaching, and learning in urban science classrooms as both a theoretical approach to understanding, and way of viewing practices within these fields. By providing a new approach to theorizing the cultural misalignments that are prevalent in urban schools, I look to provide an informative tool for investigating under-discussed dynamics that impact science teaching and learning. In this body of work, I further expose the nature of the corporate|communal by describing practices that define communal practice. I do so conversant of the fact that synthesizing my previous work on corporate and communal practices necessarily pushes science education researchers and teachers to look for somewhat tactile explications of communal practices. That is to say, if communal practices do exist within the corporate structures of science classrooms, how do they present themselves and how can they be targeted? This paper begins a journey into such a study and focuses on student transactions, fundamental interactions and rituals as a key to redefining and attaining success in urban science classrooms.

Hip-hop as a resource for understanding the urban context

NASA Astrophysics Data System (ADS)

Brown, Bryan

2010-06-01

This review explores Edmin's "Science education for the hip-hop generation" by documenting how he frames hip-hop as a means to access urban student culture. He argues that hip-hop is more than a mere music genre, but rather a culture that provides young people with ways of connecting to the world. Two primary ideas emerged as central to his work. First, he contends that students develop communal relationships and collective identities based on the common experiences expressed in hip-hop. Second, he identifies how the conscious recognition of institutional oppression serves a central feature in urban schools. Emdin's rich, and personal call for a greater understanding of hip-hop culture provides the text with an unmatched strength. He skillfully uses personal narratives from his own experience as well as quotes and references from hip-hop songs to make the nuances of hip hop transparent to science educators. Conversely, the limitation of this text is found in its unfulfilled promise to provide pragmatic examples of how to engage in a hip-hop based science education. Emdin's work is ultimately valuable as it extends our current knowledge about urban students and hip-hop in meaningful ways.

Addressing social aspects associated with wastewater treatment facilities

DOE Office of Scientific and Technical Information (OSTI.GOV)

Padilla-Rivera, Alejandro; Morgan-Sagastume, Juan Manuel; Noyola, Adalberto

In wastewater treatment facilities (WWTF), technical and financial aspects have been considered a priority, while other issues, such as social aspects, have not been evaluated seriously and there is not an accepted methodology for assessing it. In this work, a methodology focused on social concerns related to WWTF is presented. The methodology proposes the use of 25 indicators as a framework for measuring social performance to evaluate the progress in moving towards sustainability. The methodology was applied to test its applicability and effectiveness in two WWTF in Mexico (urban and rural). This evaluation helped define the key elements, stakeholders andmore » barriers in the facilities. In this context, the urban facility showed a better overall performance, a result that may be explained mainly by the better socioeconomic context of the urban municipality. Finally, the evaluation of social aspects using the semi-qualitative approach proposed in this work allows for a comparison between different facilities and for the identification of strengths and weakness, and it provides an alternative tool for achieving and improving wastewater management. - Highlights: • The methodology proposes 25 indicators as a framework for measuring social performance in wastewater treatment facilities. • The evaluation helped to define the key elements, stakeholders and barriers in the wastewater treatment facilities. • The evaluation of social aspects allows the identification of strengths and weakness for improving wastewater management. • It provides a social profile of the facility that highlights the best and worst performances.« less

Resilience and risk management in the urban project

Our study focus on the recourse of resilience concept in an urban environment coupled with risk management concerns. The urban resilience is subject to interpretation according to the expertise fields and the using context. It brings underlying concepts of time and space out. For its part, the urban environment is complex because of the elements multitude which makes up it on a dense area as much humanly, structurally, materially as functionally. The resilience polysemy rediscovers within the risk management and is confronted with the operational expectation that she arouses in this field. Between absorption, recovery, adaptability or else effectiveness, the level of requirement of the urban area could be abundant and varied to a system to another and in front of a risk to another. The capability of the urban systems to integrate the outstanding risk scope could be reinforce through the use of spatialisation tools. The access to these knowledge more and more widespread makes the changing of spatial and temporal scales thought easier in the urban project approach along with the sharing of citizen and territorial actions and innovations. Our work gets into position between resilience and urban planning. Based on bibliography and urban planning feedback in front of risks, we envisage to study the achievement of the urban planning in the field of vulnerable districts or buildings. Our aim tends torwards characterise urban resilience in risk field through spatialisation tool setting up.

Blake, Christine E.; Wethington, Elaine; Farrell, Tracy J.; Bisogni, Carole A.; Devine, Carol M.

2012-01-01

Employed parents’ work and family conditions provide behavioral contexts for their food choices. Relationships between employed parents’ food-choice coping strategies, behavioral contexts, and dietary quality were evaluated. Data on work and family conditions, sociodemographic characteristics, eating behavior, and dietary intake from two 24-hour dietary recalls were collected in a random sample cross-sectional pilot telephone survey in the fall of 2006. Black, white, and Latino employed mothers (n=25) and fathers (n=25) were recruited from a low/moderate income urban area in upstate New York. Hierarchical cluster analysis (Ward’s method) identified three clusters of parents differing in use of food-choice coping strategies (ie, Individualized Eating, Missing Meals, and Home Cooking). Cluster sociodemographic, work, and family characteristics were compared using χ2 and Fisher’s exact tests. Cluster differences in dietary quality (Healthy Eating Index 2005) were analyzed using analysis of variance. Clusters differed significantly (P≤0.05) on food-choice coping strategies, dietary quality, and behavioral contexts (ie, work schedule, marital status, partner’s employment, and number of children). Individualized Eating and Missing Meals clusters were characterized by nonstandard work hours, having a working partner, single parenthood and with family meals away from home, grabbing quick food instead of a meal, using convenience entrées at home, and missing meals or individualized eating. The Home Cooking cluster included considerably more married fathers with nonemployed spouses and more home-cooked family meals. Food-choice coping strategies affecting dietary quality reflect parents’ work and family conditions. Nutritional guidance and family policy needs to consider these important behavioral contexts for family nutrition and health. PMID:21338739

Measuring health and its determinants in urban populations is essential to effectively develop public health policies maximizing health gain within this context. Adolescents are important in this regard given the origins of leading causes of morbidity and mortality develop pre-adulthood. Comprehensive, accurate and comparable information on adolescent urban health indicators from heterogeneous urban contexts is an important challenge. EURO-URHIS 2 aimed to develop standardized tools and methodologies collecting data from adolescents across heterogenous European urban contexts. Questionnaires were developed including (i) comprehensive assessment of urban health indicators from 7 pre-defined domains, (ii) use of previously validated questions from a literature review and other European surveys, (iii) translation/back-translation into European languages and (iv) piloting. Urban area-specific data collection methodologies were established through literature review, consultation and piloting. School-based surveys of 14-16-year olds (400-800 per urban area) were conducted in 13 European countries (33 urban areas). Participation rates were high (80-100%) for students from schools taking part in the surveys from all urban areas, and data quality was generally good (low rates of missing/spoiled data). Overall, 13 850 questionnaires were collected, coded and entered for EURO-URHIS 2. Dissemination included production of urban area health profiles (allowing benchmarking for a number of important public health indicators in young people) and use of visualization tools as part of the EURO-URHIS 2 project. EURO-URHIS 2 has developed standardized survey tools and methodologies for assessing key measures of health and its determinants in adolescents from heterogenous urban contexts and demonstrated the utility of this data to public health practitioners and policy makers. © The Author 2015.

The relationship between urban development and hydro-environmental change, particularly with regard to the subsurface environment is examined for three coastal cities affected by Asian monsoons (Tokyo and Osaka in Japan, and Bangkok in Thailand). Major differences in subsurface changes among these cities are closely related to city size, urban structure, and the timing, stage and extent of urbanization as well as the natural environment. The work shows that the urban development has not affected the Bangkok subsurface hydro-environment in the same way it has in Tokyo and Osaka. Three reasons for the difference account for this, (1) Bangkok's abundant annual rainfall, (2) Bangkok has the smallest ratio of impervious pavement surface area, meaning that surface water can more easily infiltrate underground., (3) the degree and extent of urbanization. Bangkok's subsurface hydro-environment has not been heavily affected because underground development has not yet reached deep subterranean areas. By researching yet more cities, at different stages of urbanization to that of Tokyo, Osaka and Bangkok, we plan to quantitatively examine urbanization and its influence on subsurface hydro-environments. This research will help limit damage to developing cities that are not yet experiencing subsurface failures but which are expected to confront these problems in the future.

Low-income urban working mothers face many challenges in their domestic, environmental, and working conditions that may affect their mental health. In India, a high prevalence of mental health disorders has been recorded in young women, but there has been little research to examine the factors that affect their mental health at home and work. Through a primarily qualitative approach, we studied the relationship between work, caring for family, spousal support, stress relief strategies and mental health amongst forty eight low-income working mothers residing in urban slums across Bangalore, India. Participants were construction workers, domestic workers, factory workers and fruit and vegetable street vendors. Qualitative data analysis themes included state of mental health, factors that affected mental health positively or negatively, manifestations and consequences of stress and depression, and stress mitigators. Even in our small sample of women, we found evidence of extreme depression, including suicidal ideation and attempted suicide. Women who have an alcoholic and/or abusive husband, experience intimate partner violence, are raising children with special needs, and lack adequate support for child care appear to be more susceptible to severe and prolonged periods of depression and suicide attempts. Factors that pointed towards reduced anxiety and depression were social support from family, friends and colleagues and fulfilment from work. This qualitative study raises concerns that low-income working mothers in urban areas in India are at high risk for depression, and identifies common factors that create and mitigate stress in this population group. We discuss implications of the findings for supporting the mental health of urban working women in the Indian context. The development of the national mental health policy in India and its subsequent implementation should draw on existing research documenting factors associated with negative mental health amongst specific population groups in order to ensure greater impact.

Institutions in transitioning peri-urban communities: spatial differences in groundwater access

NASA Astrophysics Data System (ADS)

Gomes, Sharlene L.; Hermans, Leon M.

2016-05-01

Urbanization creates challenges for water management in an evolving socio-economic context. This is particularly relevant in transitioning peri-urban areas like Khulna, Bangladesh where competing demands have put pressure on local groundwater resources. Users are unable to sufficiently meet their needs through existing institutions. These institutions provide the rules for service provision and act as guidelines for actors to resolve their water related issues. However, the evolving peri-urban context can produce fragmented institutional arrangements. For example in Khulna, water supply is based on urban and rural boundaries that has created water access issues for peri-urban communities. This has motivated local actors to manage their groundwater needs in various ways. General institutional theories are well developed in literature, yet little is known about institutions in transitioning peri-urban areas. Institutions that fail to adapt to changing dynamics run the risk of becoming obsolete or counter-productive, hence the need for investigating institutional change mechanisms in this context. This paper examines peri-urban case studies from Khulna using the Institutional Analysis and Development framework to demonstrate how institutions have contributed to spatial differences in groundwater access with local actors investing in formal and informal institutional change as a means of accessing groundwater.

The paper integrates theories on stratification and social change and exploits the innovative design and measurement of the China Labor-force Dynamics Survey to minimize the under-coverage problem of the rural-urban migratory experience. Our analysis provides several fresh findings: (1) at-birth rural household registration (hukou) status leads to a greater probability of spatial mobility and career advancement than at-birth urban hukou status does; (2) education and gender differentiates rural-origin people, increasing the heterogeneity of urban labor and decreasing the heterogeneity of rural labor; (3) hukou policy relaxation favors later cohorts over earlier cohorts; and (4) among demographically comparable people, having experienced spatial mobility is correlated with having career advancement experience. Work organizations are found to be the arena where the two dimensions of mobility can happen jointly. Our findings provide a rich context for understanding the management and organization of Chinese labor. PMID:29129981

Accurate assessments of the population exposed to seismic hazard are crucial in seismic risk mapping. Recent rapid urbanization in China has resulted in substantial changes in the size and structure of the population exposed to seismic hazard. Using the latest population census data and seismic maps, this work investigated spatiotemporal changes in the exposure of the population in the most seismically hazardous areas (MSHAs) in China from 1990 to 2010. In the context of rapid urbanization and massive rural-to-urban migration, nearly one-tenth of the Chinese population in 2010 lived in MSHAs. From 1990 to 2010, the MSHA population increased by 32.53 million at a significantly higher rate of change (33.6%) than the national average rate (17.7%). The elderly population in MSHAs increased by 81.4%, which is much higher than the group’s national growth rate of 58.9%. Greater attention should be paid to the demographic changes in earthquake-prone areas in China.

Previous researchers had not yet examined the association between socioeconomic status (SES) and health-related quality of life (HRQOL) in urban China. The present study attempts to assess HRQOL of lower-SES populations in urban China in comparison with middle- and high-SES populations, and then to examine the mediating role of sense of control between SES and HRQOL. A national representative sample of 1,856 participants responded to the HRQOL survey using the 12-item Short Form Health Survey (SF-12), conducted by the Chinese General Social Survey research team in 2010. The results showed that lower-SES populations reported lower HRQOL than middle- and high-SES populations. Sense of control could partially mediate the association between social class and HRQOL. These findings will generate significant policy and practice implications for identifying those at particular risk for lower HRQOL and, accordingly, suggesting ways to improve their HRQOL through specific social work interventions in urban China's context. © 2016 National Association of Social Workers.

Global literature has suggested a negative impact of acculturative stress on both physical and mental health among international migrants. In China, approximately 20 percent of its population is rural-to-urban migrant workers and there are significant cultural differences between rural and urban societies, but no data are available regarding the acculturative stress of Chinese migrant workers. This study aimed to explore the forms and contexts of acculturative stress among Chinese migrant workers. Qualitative data were collected from four focus group discussions with 17 Chinese rural-to-urban migrant workers and three individual interviews with three medical professionals who provided mental health services for factory-workers in Shenzhen, China. The data in the current study showed that rural-to-urban migrant workers in China had experienced various forms of acculturative stress including difficulties in adapting to the environment, work-related stress, family-related stress, financial hardship, and lack of sense of belonging to cities. Rural-to-urban migration in China is a challenging transition with significant acculturative stress and demands for major adjustments among migrant workers. The assessment and management of acculturative stress is a necessary first step in providing mental health services to migrant workers.

Over recent decades, the study of psychological restoration has attracted a considerable amount of interest within and without the boundaries of environmental psychology, with most of the work focused on analyzing restoration in natural contexts. However, little attention has been paid to the (possible) restorative potential of urban settings, as they have usually been expected not to be restorative and to present some elements that might imply negative health outcomes in the short and long term. In this field study, our aim was to evaluate restoration in urban squares. To this end, we measured participants' attentional and affective states both before and after spending half an hour in an urban square. A sample of 46 subjects contemplated and walked through one of the two selected squares that differed in restorative potential (PRS). Analyses revealed a statistically significant increase in cognitive performance and a decrease in negative affect in both squares. They also showed that participants reported greater stress recovery rates in one of the settings. These results support the idea that cities can be potentially restorative and justify the relevance of a research area focused on the urban designs, which may offer psychological benefits to urban citizens.

Estimates suggest that over 90 % of population increase in the least developed countries over the next four decades will occur in urban areas. These increases will be driven both by natural population growth and rural-urban migration. Moreover, despite its status as the world's least urbanized region, the urban population in the sub-Saharan Africa region is projected to increase from under 40 % currently to over 60 % by 2050. Currently, approximately 70 % of all urban residents in the region live in slums or slum-like conditions. Sexual and reproductive health (SRH) risks for the urban poor are severe and include high rates of unwanted pregnancies, sexually transmitted infections, and poor maternal and child health outcomes. However, the links between poverty, urbanization, and reproductive health priorities are still not a major focus in the broader development agenda. Building on theoretical and empirical data, we show that SRH in urban contexts is critical to the development of healthy productive urban populations and, ultimately, the improvement of quality of life. We posit that a strategic focus on the sexual and reproductive health of urban residents will enable developing country governments achieve international goals and national targets by reducing health risks among a large and rapidly growing segment of the population. To that end, we identify key research, policy and program recommendations and strategies required for bringing sexual and reproductive health in urban contexts to the forefront of the development agenda.

Lower status jobs, high workloads and lack of control at work have been associated with less healthful diets, but the ways through which work is connected to food choices are not well understood. This analysis was an examination of workers' experience of the relationship of their jobs to their food choices. Fifty-one multi-ethnic, urban, low- and moderate-income adults living in Upstate New York in 1995 participated in a qualitative interview study of fruit and vegetable choices and discussed employment and food choices. The workers who participated in this study described a dynamic relationship between work and food choices that they experienced in the context of their other roles and values. These workers presented a relationship that was characterized by positive and negative spillover between their jobs and their ability to fulfill family roles and promote personal health, linked by a spectrum of food choice strategies. Participants' narratives fit into three different domains: characterizations of work and their resources for food choice, strategies used to manage food choices within the constraints of work, and affect related to the negative and positive spillover of these strategies on family roles and on personal food choices. Characterizations of work as demanding and limiting or demanding and manageable differentiated participants who experienced their food choice strategies as a source of guilt and dissatisfaction (negative spillover) from those who experienced food choices as a source of pride and satisfaction (positive spillover). Ideals and values related to food choice and health were balanced against other values for family closeness and nurturing and personal achievement. Some participants found work unproblematic. These findings direct attention to a broad conceptualization of the relationship of work to food choices in which the demands and resources of the work role are viewed as they spill over into the social and temporal context of other roles and values.

The sustainability agenda has maintained its importance since the days, when the production system took its capitalist form, as well as the population in the urban areas started to rise. Increasing number of both goods and the people have caused the degradation of the certain systems, which generate the urban areas. These systems could mainly be classified as social, environmental, physical and economical systems. Today, urban areas still have difficulty to protect those systems, due to the significant demand of the population. Therefore, studies related with the sustainable issues are significant in the sense of continuity of the urban systems. Therefore, in this paper, those studies in the context of the effects of physical decisions taken in the spatial planning process on urban sustainability, will be examined. The components of the physical decisions are limited to land use, density and design. Land use decisions will be examined in the context of mixed land use. On the other hand, decisions related with density will be analyzed in the sense of population density and floor area ratio (FAR). Besides, design decisions will be examined, by linking them with neighborhood design criteria. Additionally, the term of urban sustainability will only be limited to its social and environmental contexts in this study. Briefly stated, studies in the sustainable literature concerned with the effects of land use, density and design decisions taken in the spatial planning process on the social and environmental sustainability will be examined in this paper. After the compilation and the analyze of those studies, a theoretical approach will be proposed to determine social and environmental sustainability in the context of land use, density and design decisions, taken in the spatial planning process.

In Mexico, youth face difficulties in obtaining reliable information on sex education and family planning through existing community programs. Two alternative strategies to provide these services are being tested in poor urban areas of Monterrey. In one experimental area, Integrated Youth Centers were established, which provide sex education and family planning services as well as counseling, academic tutoring, and recreational activities. In another area, trained young adults and community counselors work through informal networks to provide sex education and family planning information. Both utilization and the cost of these services are examined in the context of plans for expanding coverage in Mexico-U.S. border areas.

breast feeding is an essential source of nutrition among young babies; however, in Pakistan a gradual decline in prevalence of breast feeding, especially among urban working mothers, has been reported. Previous studies among Pakistani urban working mothers have revealed that ensuring exclusivity and continuation of breast feeding is challenging if social and/or workplace environmental support is minimal or absent. This problem indicated a crucial need to assess availability of breast-feeding support for Pakistani urban working mothers by using a comprehensive, reliable, and validated tool in their national language (Urdu). to develop and test the psychometric properties of the 'Perceived Breastfeeding Support Assessment Tool' (PBSAT) that can gauge Pakistani urban working mothers' perceptions about breast-feeding support. this methodological research was undertaken in five phases. During phase I, a preliminary draft of the PBSAT was developed by using the Socio-ecological model, reviewing literature, and referring to two United States based tools. In Phase II, the instrument was evaluated by seven different experts, and, in Phase III, the instrument was revised, translated, and back translated. In Phase IV, the tool was pilot tested among 20 participants and then modified on the basis of statistical analysis. In Phase V, the refined instrument was tested on 200 breast-feeding working mothers recruited through purposive sampling from the government and private health-care settings in Karachi, Pakistan. Approvals were received from the Ethical Review Committees of the identified settings. the 29-item based PBSAT revealed an acceptable inter-rater reliability of 0.95, and an internal consistency reliability coefficient (Cronbach's alpha) of 0.85. A construct validity assessment through Exploratory Factor Analysis revealed that the PBSAT has two dimensions, 'workplace environmental support' (12 items; α=0.86) and 'social environmental support' (17 items; α=0.77). the study developed a 29-item based two-dimensional tool (in Urdu) that has acceptable psychometric properties. The PBSAT is context specific, comprehensive, and user-friendly, so it can be administered by health-care workers, employers, policy makers, and researchers to improve the quality of services of breast-feeding urban working mothers, and could ultimately improve child health in Pakistan.

In urban computing environments, all of services should be based on the interaction between humans and environments around them, which frequently and ordinarily in home and office. This paper propose an u-service model based on a smart phone for urban computing environments. The suggested service model includes a context-aware and personalized service scenario development environment that can instantly describe user's u-service demand or situation information with smart devices. To do this, the architecture of the suggested service model consists of a graphical service editing environment for smart devices, an u-service platform, and an infrastructure with sensors and WSN/USN. The graphic editor expresses contexts as execution conditions of a new service through a context model based on ontology. The service platform deals with the service scenario according to contexts. With the suggested service model, an user in urban computing environments can quickly and easily make u-service or new service using smart devices.

Surface water degradation resulting from the effects of urbanization on hydrology, water quality, habitat as well as ecological and environmental compartments represents an issue of primary focus for multiple agencies at the national, regional and local levels. Many management actions are needed throughout urban watersheds to achieve the desired effects on flow mitigation and pollutant reduction, but no single standardized solution can be effective in all locations. In this work, the distributed hydrological model MOBIDIC, already applied for hydrological balance simulations and flood prevention in different Italian regions, is adapted to the urban context (MOBIDIC-U) in order to evaluate alternative plans for stormwater quality management and flow abatement techniques through the adoption of green infrastructures (GIs). In particular the new modules included in MOBIDIC-U allow to (i) automatically define the upstream flow path as well as watershed boundary starting from a selected watershed closure point on the urban drainage network and (ii) obtain suitable graphical outputs for the visualization of flow peak and volume attenuation at the closure point. Moreover, MOBIDIC-U provides a public domain tool capable of evaluating the optimal location, type, and cost of the stormwater management practices needed to meet water quantity and quality goals. Despite the scalability of the model to different urban contexts, the current version of MOBIDIC-U has been developed for the area of the metropolitan city of Milan, Northern Italy. The model is implemented on a GIS platform, which already contains (i) the structure of the urban drainage network of the metropolitan city of Milan; (ii) the database of actual geomorphological and meteorological data for the previous domain (iii) the list of potential GIs, their standard size, installation and maintenance costs. Therefore, MOBIDIC-U provides an easy to use tool to local professionals to design and evaluate urban stormwater management measures based on GIs.

Is urbanization a risk factor for substance misuse?

2008-07-01

More than half of the world's population is living in urban areas, but the evidence about urban-rural differences in drug use is not clearly defined. The present paper aims to review the international literature addressing the role of urbanization and related parameters in association with substance misuse. In particular, the evidence of urbanization being a risk factor for substance misuse is examined. Although it has been suggested that substance misuse is typically a characteristic of large urban areas, this did not appear to be a consistent observation from the literature review. Furthermore, the urban context may offer a relative proximity of health services and prompter emergency intervention in case of overdose. Although more efforts have to be put into explaining substance misuse in general, identifying which characteristics of the urban context are modifiable, and under what circumstances, is an important theoretical, empirical, and public health question.

Urbanism, Neighborhood Context, and Social Networks.

PubMed

Cornwell, Erin York; Behler, Rachel L

Theories of urbanism suggest that the urban context erodes individuals' strong social ties with friends and family. Recent research has narrowed focus to the neighborhood context, emphasizing how localized structural disadvantage affects community-level cohesion and social capital. In this paper, we argue that neighborhood context also shapes social ties with friends and family- particularly for community-dwelling seniors. We hypothesize that neighborhood disadvantage, residential instability, and disorder restrict residents' abilities to cultivate close relationships with neighbors and non-neighbor friends and family. Using data from the National Social Life, Health, and Aging Project (NSHAP), we find that older adults who live in disadvantaged neighborhoods have smaller social networks. Neighborhood disadvantage is also associated with less close network ties and less frequent interaction - but only among men. Furthermore, residents of disordered neighborhoods have smaller networks and weaker ties. We urge scholars to pay greater attention to how neighborhood context contributes to disparities in network-based access to resources.

The aim of this study is to characterize urban spaces, which combine landscape, acoustics, and lighting, and to investigate people's perceptions of urban soundscapes through quantitative and qualitative analyses. A general questionnaire survey and soundwalk were performed to investigate soundscape perception in urban spaces. Non-auditory factors (visual image, day lighting, and olfactory perceptions), as well as acoustic comfort, were selected as the main contexts that affect soundscape perception, and context preferences and overall impressions were evaluated using an 11-point numerical scale. For qualitative analysis, a semantic differential test was performed in the form of a social survey, and subjects were also asked to describe their impressions during a soundwalk. The results showed that urban soundscapes can be characterized by soundmarks, and soundscape perceptions are dominated by acoustic comfort, visual images, and day lighting, whereas reverberance in urban spaces does not yield consistent preference judgments. It is posited that the subjective evaluation of reverberance can be replaced by physical measurements. The categories extracted from the qualitative analysis revealed that spatial impressions such as openness and density emerged as some of the contexts of soundscape perception. © 2011 Acoustical Society of America

Habitat and landscape characteristics underlying anuran community structure along an urban-rural gradient.

Pillsbury, Finn C; Miller, James R

2008-07-01

Urbanization has been cited as an important factor in worldwide amphibian declines, and although recent work has illustrated the important influence of broad-scale ecological patterns and processes on amphibian populations, little is known about the factors structuring amphibian communities in urban landscapes. We therefore examined amphibian community responses to wetland habitat availability and landscape characteristics along an urban-rural gradient in central Iowa, USA, a region experiencing rapid suburban growth. We conducted call surveys at 61 wetlands to estimate anuran calling activity, and quantified wetland habitat structure and landscape context. We used canonical correspondence analysis (CCA) to examine patterns in anuran community structure and identify the most important variables associated with those patterns. Urban density at the landscape scale had a significant negative influence on overall anuran abundance and diversity. While every species exhibited a decrease in abundance with increasing urban density, this pattern was especially pronounced for species requiring post-breeding upland habitats. Anurans most affected by urbanization were those associated with short hydroperiods, early breeding activity, and substantial upland habitat use. We suggest that broad-scale landscape fragmentation is an important factor underlying anuran community structure in this region, possibly due to limitations on the accessibility of otherwise suitable habitat in fragmented urban landscapes. This study underscores the importance of a regional approach to amphibian conservation in urban and urbanizing areas; in fragmented landscapes, a network of interconnected wetland and upland habitats may be more likely to support a successful, diverse anuran community than will isolated sites.

It is well known that many of the European UNESCO World Heritage sites and cities are closely related to water bodies in their different forms, as they have close links with the sea (such as Venice, San Rossore, Dubrovnik) and with rivers (like Florence, Rome, Ferrara, etc). Surely there are many others with problems of water supply, water treatment, wastewater disposal, etc. The main objective of the work is therefore to institute measures which will permit to contribute towards the conservation and protection of such precious heritage sites and cities, particularly in coastal area, in the context of present urbanization and climatic modifications. It has therefore become necessary to identify and classify not only urban centres of historical importance but also historical hydraulic structures and works developed for both beneficial and harmful water management, hereinafter referred to as good water and bad water respectively. Another objective is to raise the awareness of institutions and the public in general on the historical values of Heritage cities and hence the need to protect them. The main activities of the study are directed at the following: 1) Collection and collation of information and documentation on water sources, intakes and distribution structures, flood events especially around urban centres, structural characteristics of bridges, defensive hydraulic structures of rivers from ancient times to the present. 2) Creation of an integrative water-urban data base in the form of a virtual museum. 3) Design and preparation of feasibility strategies for relevant historical works for renovation purposes and also hydrological analysis of flood events and reconstruction of historical flood series towards re-qualification of urban and riverine environments in the face of climate change. 4) Hydraulic risk analysis of complex hydraulic systems, performing flooding scenarios at different flow rates.

Faced to the economic and energetic context of our society, it is widely recognised that an alternative to fossil fuels and oil-based products will be needed in the nearest future. In this way, development of urban biorefinery could bring many solutions to this problem. Study of the implementation of urban biorefinery highlights two sustainable configurations that provide solutions to the Walloon context by promoting niche markets, developing circular economy and reducing transport of supply feedstock. First, autonomous urban biorefineries are proposed, which use biological waste for the production of added value molecules and/or finished products and are energetically self-sufficient. Second, integrated urban biorefineries, which benefit from an energy supply from a nearby industrial activity. In the Walloon economic context, these types of urban biorefineries could provide solutions by promoting niche markets, developing a circular economy model, optimise the transport of supply feedstock and contribute to the sustainable development. © The Author(s) 2015.

Rural-urban inequities in childhood immunisation in Nigeria: The role of community contexts

2011-01-01

Abstract Context Childhood vaccinations are one of the most cost-effective means of reducing negative child health outcomes. Despite the benefits of immunisation, inequities persist both between and within rural-urban areas in Nigeria. Objectives To assess the role of community contexts on rural-urban inequities in full immunisation uptake amongst children 12 months of age and older. Methods Data from the 2003 Nigeria Demographic and Health Survey including 6029 live born children from 3725 women aged 15–49 years were examined using multilevel regression analysis. Results Rural children were disadvantaged both in the proportion receiving full immunisation and individual vaccines. Contextual or community-level factors such as community prenatal care by doctor, community hospital delivery, and region of residence accounted for significant rural-urban inequities in full immunisation. Conclusion This study stresses the need for community-level interventions aimed at closing rural-urban inequities in the provision of maternal and child health care services.

The deployment of Intelligent Vehicles in urban environments requires reliable estimation of positioning for urban navigation. The inherent complexity of this kind of environments fosters the development of novel systems which should provide reliable and precise solutions to the vehicle. This article details an advanced GNSS/IMU fusion system based on a context-aided Unscented Kalman filter for navigation in urban conditions. The constrained non-linear filter is here conditioned by a contextual knowledge module which reasons about sensor quality and driving context in order to adapt it to the situation, while at the same time it carries out a continuous estimation and correction of INS drift errors. An exhaustive analysis has been carried out with available data in order to characterize the behavior of available sensors and take it into account in the developed solution. The performance is then analyzed with an extensive dataset containing representative situations. The proposed solution suits the use of fusion algorithms for deploying Intelligent Transport Systems in urban environments. PMID:23223080

The urban ecosystem is a complex, metastable system with highly coupled flows of mass, energy, people and capital. Their sustainability is in part linked to the existence of green spaces which provide important ecosystem services, whose sustainable management requires quantification of their benefits in terms of impacts on water, carbon and energy fluxes. An exploration of problems of optimal management of such green urban spaces and the related biogeochemical fluxes is presented, extending probabilistic ecohydrological models of the soil-plant system to the urban context, where biophysical and ecological conditions tend to be radically different from the surrounding rural and natural environment (e.g. heat islands, air and water pollution, low quality soils, etc…). The coupled soil moisture, nutrient and plant dynamics are modeled to compute water requirements, carbon footprint, nutrient demand and losses, and related fluxes under different design, management and climate scenarios. The goal is to provide operative rules for a sustainable water use through focused irrigation and fertilization strategies, optimal choice of plants, soil and cultivation conditions, accounting for the typical hydroclimatic variability that occur in the urban environment.

In 2014, over half (54%) of the world's population lived in urban areas and this proportion will increase to 66% by 2050. This urbanizing trend has been accompanied by an increasing number of people living in urban poor communities and slums. Lower immunization coverage is found in poorer urban dwellers in many contexts. This study aims to identify factors associated with immunization coverage in poor urban areas and slums, and to identify interventions to improve coverage. We conducted a systematic review, searching Medline, Embase, Global Health, CINAHL, Web of Science and The Cochrane Database with broad search terms for studies published between 2000 and 2016. Of 4872 unique articles, 327 abstracts were screened, leading to 63 included studies: 44 considering factors and 20 evaluating interventions (one in both categories) in 16 low or middle-income countries. A wide range of socio-economic characteristics were associated with coverage in different contexts. Recent rural-urban migration had a universally negative effect. Parents commonly reported lack of awareness of immunization importance and difficulty accessing services as reasons for under-immunization of their children. Physical distance to clinics and aspects of service quality also impacted uptake. We found evidence of effectiveness for interventions involving multiple components, especially if they have been designed with community involvement. Outreach programmes were effective where physical distance was identified as a barrier. Some evidence was found for the effective use of SMS (text) messaging services, community-based education programmes and financial incentives, which warrant further evaluation. No interventions were identified that provided services to migrants from rural areas. Different factors affect immunization coverage in different urban poor and slum contexts. Immunization services should be designed in collaboration with slum-dwelling communities, considering the local context. Interventions should be designed and tested to increase immunization in migrants from rural areas.

Suitability assessment of the urban water management transition in the Indonesian context - A case study of Surabaya

The rapidly growing urban population, the increasing impact of climate change, and the constantly decreasing availability of the good quality water become the major triggers that force urban water professionals to continuously focus on sustainable urban water management (SUWM). The city as a focal point of population growth in the world has become a critical object for its resiliency, not only in terms of the environmental deterioration but also of the water supplies security. As a response to the current condition, the framework of urban water management transition has been introduced as a sort of transformation for a city to achieve SUWM. Water Sensitive City (WSC) is the ultimate goal of this framework which integrates water access and supply security, public health protection, flood prevention, environmental protection and livability, and economic sustainability. Recently, the urban water management transition and WSC concept are going to be implemented in some cities in Indonesia, including Surabaya. However, in addition to provide a wide range of benefits, the implementation of WSC also brings challenges. In terms of geographical and social aspect, public policy, and the citizen behavior, the cities in Indonesia are undoubtedly different with those in Australian where the concept was developed. Hence, assessing the suitability of urban water management transition in the Indonesian context can be perceived as the most important phase in this whole plan. A case study of Surabaya would be identified as a baseline to measure whether the proposed sequence of urban water management transition is suitable for Indonesian local context. The research aimed to assess the suitability of the framework to be implemented in Indonesia and to propose the modified framework which is more suitable for local context in Indonesia.

2017-01-01

While urban systems demonstrate high spatial heterogeneity, many urban planning, economic and political decisions heavily rely on a deep understanding of local neighborhood contexts. We show that the structure of 311 Service Requests enables one possible way of building a unique signature of the local urban context, thus being able to serve as a low-cost decision support tool for urban stakeholders. Considering examples of New York City, Boston and Chicago, we demonstrate how 311 Service Requests recorded and categorized by type in each neighborhood can be utilized to generate a meaningful classification of locations across the city, based on distinctive socioeconomic profiles. Moreover, the 311-based classification of urban neighborhoods can present sufficient information to model various socioeconomic features. Finally, we show that these characteristics are capable of predicting future trends in comparative local real estate prices. We demonstrate 311 Service Requests data can be used to monitor and predict socioeconomic performance of urban neighborhoods, allowing urban stakeholders to quantify the impacts of their interventions.

2014-10-01

Although ecological connectivity conservation in urban areas has recently been recognized as an important issue, less is known about its relationship to urban form and landscape pattern. This study investigates how urban morphology influences regional ecosystem pattern and landscape connectivity. Two metropolitan landscapes, Phoenix, AZ, USA, and Izmir, Turkey, were compared, both of which are fast-growing regions in their national context. A wide range of variables were considered for identifying natural and urban properties. The natural characteristics include typology of urban ecosystems, urban to natural cover ratio, dominant habitat type, urban biodiversity, landscape context, and connectivity conservation efforts. Urban parameters examine urban form, urban extent, urban cover proportion, growth rate, populations, urban gradient, major drivers of urbanization, urban density, and mode/approach of urban development. Twelve landscape metrics were measured and compared across the natural patches. Results show that there is little difference in landscape connectivity in the rural zones of Phoenix and Izmir, although Phoenix has slightly higher connectivity values. The connectivity variance in urbanized areas, however, is significantly dependent on the region. For example, Phoenix urban zones have substantially lower connectivity than either urban or suburban zones in Izmir. Findings demonstrate that small and compact urban settlements with more dense populations are more likely to conserve landscape connectivity compared to multiple-concentric but amalgamated urban form spreading all over the landscape (aka urban sprawl).

Urban policy engagement with social sustainability in metro Vancouver.

PubMed

Holden, Meg

2012-01-01

This article presents an analysis of social sustainability in comparative theoretical context and as a challenge to the post-political interpretation of sustainability in policy practice at the urban and regional scales. Metro Vancouver provides a case study for improving our understanding of the meaning of social sustainability as a framework for social policy in that it is among the handful of cities around the world currently working to define and enact social sustainability in governance terms. Results of this participant research provide evidence that some cities are politically engaging alternative development pathways using the concept of social sustainability. For sustainable development to retain its promise as an alternative policy framework for cities, social sustainability must be at the forefront.

Defining Scenarios: Linking Integrated Models, Regional Concerns, and Stakeholders

Scenarios are important tools for long-term planning, and there is great interest in using integrated models in scenario studies. However, scenario definition and assessment are creative, as well as scientific, efforts. Using facilitated creative processes, we have worked with stakeholders to define regionally significant scenarios that encompass a broad range of hydroclimatic, socioeconomic, and institutional dimensions. The regional scenarios subsequently inform the definition of local scenarios that work with context-specific integrated models that, individually, can address only a subset of overall regional complexity. Based on concerns of stakeholders in the semi-arid US Southwest, we prioritized three dimensions that are especially important, yet highly uncertain, for long-term planning: hydroclimatic conditions (increased variability, persistent drought), development patterns (urban consolidation, distributed rural development), and the nature of public institutions (stressed, proactive). Linking across real-world decision contexts and integrated modeling efforts poses challenges of creatively connecting the conceptual models held by both the research and stakeholder communities.

Urban heat fluxes in the subsurface of Cologne, Germany

NASA Astrophysics Data System (ADS)

Zhu, K.; Bayer, P.; Blum, P.

2012-04-01

Urbanization during the last hundred years has led to both environmental and thermal impacts on the subsurface. The urban heat island (UHI) effect is mostly described as an atmospheric phenomenon, where the measured aboveground temperatures in cities are elevated in comparison to undisturbed rural regions. However, UHIs can be found below, as well as above ground. A large amount of anthropogenic heat migrates into the urban subsurface, which also raises the ground temperature and permanently changes the thermal conditions in shallow aquifers. The main objective of our work is to study and determine the urban heat fluxes in Cologne, Germany, and to improve our understanding of the dynamics of subsurface energy fluxes in UHIs. Ideally, our findings will contribute to strategic and more sustainable geothermal use in cities. For a quantitative analysis of the energy fluxes within the subsurface and across the atmospheric boundary, two and three-dimensional coupled numerical flow and heat transport models were developed. The simulation results indicate that during the past hundred years, an average vertical urban heat flux that ranges between 80 and 375 mW m-2 can be deduced. Thermal anomalies have migrated into the local urban aquifer system and they reach a depth of about 150 m. In this context, the influence of the regional groundwater flow on the subsurface heat transport and temperature development is comprehensively discussed.

Environmental contexts of menopause in Spain: comparative results from recent research.

PubMed

Bernis, Cristina; Reher, David Sven

2007-01-01

This study had two main objectives: (1) to detect the differences in basic aspects of the reproductive aging process (age at menopause, menopausal symptoms, the medicalization of aging) among women from the region of Madrid, who at the time of the study were living in three different environmental contexts (rural, semiurban, and urban), and (2) to identify the main factors responsible for these differences. Data from two different research projects have been pooled for the DAMES project (Decisions At MEnopause Study), and the Ecology of Reproductive Aging Project. The sample size was 1,142, women 45 to 55 years of age (103 rural, 744 semiurban, 295 urban). Probit analysis was used to estimate median age at natural menopause in the three contexts. Rural women have a later onset of menopause (rural, 52.07 y; semiurban, 51.9 y; urban, 51.23 y) and significantly higher levels of the symptoms related to declines in estrogen, eg, hot flashes (rural, 56%; semiurban, 43%; urban, 46%; chi2=6.717, P=0.035) or loss of sexual desire (rural, 51%; semiurban, 44%; urban, 41%; chi2=24.934, P=0.001). Conversely, urban women suffer more from symptoms related to stress, eg, impatience (rural, 34%; semiurban, 25%; urban, 45%; chi2=41.328, P<0.001). The medicalization of menopause, measured in terms of both surgical menopause and the use of hormone therapy, is significantly higher in the urban population (surgical menopause: rural, 5.8%; semiurban, 8.7; urban, 10%; chi2=16.009, P<0.001). Despite these differences, levels of postmenopausal hormone therapy use are still somewhat lower than in other West European and North American populations. Two different logistic regression analyses were carried out to identify (1) factors associated with differences in ovarian aging, measured through menopausal status, and (2) factors associated with prevalence of hot flashes with respect to ovarian aging. Parity, body mass index, age, environmental context, and, slightly less so, smoking, alcohol consumption, age, education, age at menarche, and marital status all contribute significantly or nearly significantly and independently to the explanation of differences found. For the likelihood of having hot flashes, environmental context, age, education, age at menarche, menopausal status, and postmenopausal hormone therapy use all hae a significant or borderline significant effect. Significant differences have been shown to exist in rural, semiurban and urban settings in the median age at menopause, in basic symptom frequency and type, and in the levels of medicalization of the process of reproductive aging. Within multivariate regression models, it has been shown that body mass index, age, and environmental context all contribute to differences in reproductive aging. The factors associated with ovarian aging and hot flashes are comparable to those in other industrialized populations, although standard interpretations should be expanded to include context-based realities, including (1) the higher levels of modernization of urban women that influence differential behavior with respekt to risk factors at menopausal age; (2) the different ecological realities surrounding nutrition, physical activity, and social support that characterize women's period of development; and (3) the differential construction of their identity as women in terms of assertiveness, aesthetic perceptions, and the use of health services. Context does, indeed, matter.

The Sustainable Development Goal for Urban Sanitation: Africa's Statistical Tragedy Continues?

PubMed

Buckley, Robert M; Kallergis, Achilles

2018-06-01

Sanitation delivery in the urban areas of sub-Saharan African countries has been a chronic issue, particularly difficult to tackle. Under the Millennium Development Goals, the sanitation target in urban sub-Saharan Africa was missed by a wide margin and witnessed almost no improvement. After 2 years of review, the WHO/UNICEF Joint Monitoring Programme published a new measure of access to sanitation as a baseline for the Sustainable Development Goals. There are a number of improvements in the new measure. However, despite the improvements, the new measure continues to be characterized by an important flaw: it continues to disregard how shared toilet facilities contribute towards the SDG sanitation target. As a result, the new measure does not indicate whether progress is being made in low-income urban areas where a large number of households rely on shared sanitation; nor does it provide a goal that can be achieved in cities of the poorest countries over the measurement period. But, its most egregious failing is that it directs resources towards investments which will often fail cost/benefit tests. In sum, it is not a surprise that a Working Group recommended that the measure should be changed to include some shared facilities. Following the Working Group's recommendation would have avoided the adverse consequences of continued reliance on a key component of the methodology used for monitoring sanitation improvements under the Millennium Development Goals. The paper discusses the limitations of this methodology in the context of urban sub-Saharan Africa, where current sanitation conditions are seriously lacking, and the significant future urban population growth will add more pressure for the delivery of vital sanitation services.

Cultured Construction: Global Evidence of the Impact of National Values on Piped-to-Premises Water Infrastructure Development.

PubMed

Kaminsky, Jessica A

2016-07-19

In 2016, the global community undertook the Sustainable Development Goals. One of these goals seeks to achieve universal and equitable access to safe and affordable drinking water for all people by the year 2030. In support of this undertaking, this paper seeks to discover the cultural work done by piped water infrastructure across 33 nations with developed and developing economies that have experienced change in the percentage of population served by piped-to-premises water infrastructure at the national level of analysis. To do so, I regressed the 1990-2012 change in piped-to-premises water infrastructure coverage against Hofstede's cultural dimensions, controlling for per capita GDP, the 1990 baseline level of coverage, percent urban population, overall 1990-2012 change in improved sanitation (all technologies), and per capita freshwater resources. Separate analyses were carried out for the urban, rural, and aggregate national contexts. Hofstede's dimensions provide a measure of cross-cultural difference; high or low scores are not in any way intended to represent better or worse but rather serve as a quantitative way to compare aggregate preferences for ways of being and doing. High scores in the cultural dimensions of Power Distance, Individualism-Collectivism, and Uncertainty Avoidance explain increased access to piped-to-premises water infrastructure in the rural context. Higher Power Distance and Uncertainty Avoidance scores are also statistically significant for increased coverage in the urban and national aggregate contexts. These results indicate that, as presently conceived, piped-to-premises water infrastructure fits best with spatial contexts that prefer hierarchy and centralized control. Furthermore, water infrastructure is understood to reduce uncertainty regarding the provision of individually valued benefits. The results of this analysis identify global trends that enable engineers and policy makers to design and manage more culturally appropriate and socially sustainable water infrastructure by better fitting technologies to user preferences.

Do cities simulate climate change? A comparison of herbivore response to urban and global warming

USGS Publications Warehouse

Youngsteadt, Elsa; Dale, Adam G.; Terando, Adam; Dunn, Robert R.; Frank, Steven D.

2014-01-01

Cities experience elevated temperature, CO2, and nitrogen deposition decades ahead of the global average, such that biological response to urbanization may predict response to future climate change. This hypothesis remains untested due to a lack of complementary urban and long-term observations. Here, we examine the response of an herbivore, the scale insect Melanaspis tenebricosa, to temperature in the context of an urban heat island, a series of historical temperature fluctuations, and recent climate warming. We survey M. tenebricosa on 55 urban street trees in Raleigh, NC, 342 herbarium specimens collected in the rural southeastern United States from 1895 to 2011, and at 20 rural forest sites represented by both modern (2013) and historical samples. We relate scale insect abundance to August temperatures and find that M. tenebricosa is most common in the hottest parts of the city, on historical specimens collected during warm time periods, and in present-day rural forests compared to the same sites when they were cooler. Scale insects reached their highest densities in the city, but abundance peaked at similar temperatures in urban and historical datasets and tracked temperature on a decadal scale. Although urban habitats are highly modified, species response to a key abiotic factor, temperature, was consistent across urban and rural-forest ecosystems. Cities may be an appropriate but underused system for developing and testing hypotheses about biological effects of climate change. Future work should test the applicability of this model to other groups of organisms.

Situating Green Infrastructure in Context: A Framework for Adaptive Socio-Hydrology in Cities.

2017-12-01

Management of urban hydrologic processes using green infrastructure (GI) has largely focused on stormwater management. Thus, design and implementation of GI usually rely on physical site characteristics and local rainfall patterns, and do not typically account for human or social dimensions. This traditional approach leads to highly centralized stormwater management in a disconnected urban landscape, and can deemphasize additional benefits that GI offers, such as increased property value, greenspace aesthetics, heat island amelioration, carbon sequestration, and habitat for biodiversity. We propose a Framework for Adaptive Socio-Hydrology (FrASH) in which GI planning and implementation moves from a purely hydrology-driven perspective to an integrated socio-hydrological approach. This allows for an iterative, multifaceted decision-making process that would enable a network of stakeholders to collaboratively set a dynamic, context-guided project plan for the installation of GI, rather than a 'one-size-fits-all' installation. We explain how different sectors (e.g., governance, non-governmental organizations, academia, and industry) can create a connected network of organizations that work towards a common goal. Through a graphical Chambered Nautilus model, FrASH is experimentally applied to contrasting GI case studies and shows that this multi-stakeholder, connected, de-centralized network with a co-evolving decision-making project plan results in enhanced multi-functionality, potentially allowing for the management of resilience in urban systems at multiple scales.

The Project is based on the integration of archaeological methods with indirect geophysical investigations, to study the urban area, inside the “Mura Aureliane” in correspondence of the first mile of the ancient Appia way (Roma, Italy). This programme is characterised by: (a) Topographic studies through the evaluation of the connections between the ancient urban “regiones” I and XII, the ancient and medieval road network, the typology of public and private monuments of ancient age, the organisation of ancient necropolis, the study of the religious buildings of the ancient and medieval age and the evaluation of the environment; (b) Epigraphic studies to make card indexing of the known epigraphic context, the reconstruction of the epigraphic context missing during the excavations made between the XV and XIX centuries; (c) The study of documentation analysis of the documentation related to the building’s properties of the selected area for the period between XVI and XX centuries, to reconstruct the medieval and modern urban landscape; (d) Non-destructive geophysical investigations to locate the hypothised archaeological structures. In this work the results of a high-resolution GPR survey carried out, during October 2001 May 2002, to detect archaeological remains are presented. A high-resolution data acquisition method has been adopted with the aim to reconstruct a global vision of investigated area. Taking into account the known archaeological information, the geophysical results are discussed and preliminarily interpreted.

Decentralised systems - definition and drivers in the current context.

PubMed

Sharma, Ashok K; Tjandraatmadja, Grace; Cook, Stephen; Gardner, Ted

2013-01-01

This paper explores the current context for decentralised approaches in the provision of urban water services. It examines the recent history of decentralised systems' implementation in Australia and identifies its drivers. The drivers included addressing capacity constraints of centralised systems, mitigating the environmental impact of urban development, and increasing the resilience of urban water systems to episodic droughts and the projected impacts of climate change. The concepts of integrated urban water management and water sensitive urban design were prevalent in many of the innovative approaches used for the provision of decentralised urban water services. However, there remains a degree of confusion among water professionals in the terminology adopted for on-site and decentralised systems. Based on a literature review, consultation with water industry professionals and examination of decentralised urban developments in Australia, this paper has developed a generalised definition of decentralised systems for adoption across the water sector. The definition encompasses the various development scales in which decentralised systems are implemented, and reflects the new functions and characteristics inherent to those systems.

Deal, Brian; Petri, Aaron; Pan, Haozhi; Goldenberg, Romain; Kalantari, Zahra; Cvetkovic, Vladimir

2017-04-01

The increasing pressure of climate change has inspired two normative agendas; socio-technical transitions and socio-ecological resilience, both sharing a complex-systems epistemology (Gillard et al. 2016). Socio-technical solutions include a continuous, massive data gathering exercise now underway in urban places under the guise of developing a 'smart'(er) city. This has led to the creation of data-rich environments where large data sets have become central to monitoring and forming a response to anomalies. Some have argued that these kinds of data sets can help in planning for resilient cities (Norberg and Cumming 2008; Batty 2013). In this paper, we focus on a more nuanced, ecologically based, socio-environmental perspective of resilience planning that is often given less consideration. Here, we broadly discuss (and model) the tightly linked, mutually influenced, social and biophysical subsystems that are critical for understanding urban resilience. We argue for the need to incorporate these sub system linkages into the resilience planning lexicon through the integration of systems models and planning support systems. We make our case by first providing a context for urban resilience from a socio-ecological and planning perspective. We highlight the data needs for this type of resilient planning and compare it to currently collected data streams in various smart city efforts. This helps to define an approach for operationalizing socio-environmental resilience planning using robust systems models and planning support systems. For this, we draw from our experiences in coupling a spatio-temporal land use model (the Landuse Evolution and impact Assessment Model (LEAM)) with water quality and quantity models in Stockholm Sweden. We describe the coupling of these systems models using a robust Planning Support System (PSS) structural framework. We use the coupled model simulations and PSS to analyze the connection between urban land use transformation (social) and water (environmental) systems within the context of planning for a more resilient Stockholm. This work shows that complex urban systems models can help bridge the divide between socio-technological and socio-environmental systems knowledge and achieving resilient urban areas.

Care and cultural context of Lebanese Muslim immigrants: using Leininger's theory.

PubMed

Luna, L

1994-01-01

The purpose of this ethnonursing study was to describe and analyze the meanings and experiences of care for Lebanese Muslims as influenced by cultural context in selected natural and community settings. Leininger's theory of Cultural Care Diversity and Universality served as the conceptualizing frame-work for the study. Research questions focused on discovering the meanings and experiences of care as influenced by world view, social structure, and cultural context in the hospital, clinic, and home. Ethno-nursing research methods were used with key and general informants in an urban US community. The majority of informants were new immigrants living less than 10 years in the US. Universal themes of care that were similar in the three contexts reflected care as a religious obligation in Islam, care as equal but different gender role responsibilities, and care as individual and collective meanings of honor. This article also presents findings related to gender role responsibilities. Nursing decisions and actions using Leininger's three modes were identified to achieve culturally congruent nursing care.

Urban Poverty and Neighborhood Effects on Crime: Incorporating Spatial and Network Perspectives

Graif, Corina; Gladfelter, Andrew S.; Matthews, Stephen A.

2015-01-01

Research on neighborhoods and crime is on a remarkable growth trajectory. In this article, we survey important recent developments in the scholarship on neighborhood effects and the spatial stratification of poverty and urban crime. We advance the case that, in understanding the impact of neighborhoods and poverty on crime, sociological and criminological research would benefit from expanding the analytical focus from residential neighborhoods to the network of neighborhoods individuals are exposed to during their daily routine activities. This perspective is supported by reemerging scholarship on activity spaces and macro-level research on inter-neighborhood connections. We highlight work indicating that non-residential contexts add variation in criminogenic exposure, which in turn influence offending behavior and victimization risk. Also, we draw on recent insights from research on gang violence, social and institutional connections, and spatial mismatch, and call for advancements in the scholarship on urban poverty that investigates the salience of inter-neighborhood connections in evaluating the spatial stratification of criminogenic risk for individuals and communities.

In India, the prevalence of smoking among women is increasing, and the reasons behind this are unclear. We aimed to study the factors leading to initiation and maintenance of the smoking habit in women in Pune, India. Twenty-seven urban women smokers, ranging from 21 to 60 years of age (31.96 ± 10.70 years), were interviewed between September 2015 and February 2016. The in-depth interviews consisted of questions on pre-decided categories, including initiation, motivation to continue smoking, and risk perception. Thematic analysis revealed that peer pressure, curiosity, fascination, experimentation, and belonging to a group were factors that led to initiation, while lack of alternatives for stress relief, work environments, and lack of leisure time activities provided circumstances to continue smoking. Participants recognized a sense of liberation and independence from smoking cigarettes and perceived health risks as minor and distant. These findings can be used to develop or modify interventions to prevent and control smoking among urban Indian women.

Cinara cupressi (Buckton) is an important aphid pest of the Cupressaceae family, originally reported in Chile in 2003. Since then, it has spread over 4,000 km, contributing to conservation issues, mostly associated with native and urban trees of the Cupressaceae. In the present work, the morphometric variation of C. cupressi was examined to determine if the species present in Chile corresponds to a specific entity, and to identify variations among specimens from different localities in the study area. Colonies were collected from urban trees from northern, central, and southern Chile. Morphometric data for 14 characters in aphids from 63 localities in all the distribution ranges were measured and analyzed by multivariate analysis. Results showed that the species present in Chile corresponds to C. cupressi like a single specific entity, showing no morphological variation across the regions sampled. Our data will be discussed within the context of correct taxonomic identification for the implementation of effective biological control strategies.

[Transitions in context: findings related to rural-to-urban migration and chronic non-communicable diseases in Peru].

Miranda, J Jaime; Wells, Jonathan C K; Smeeth, Liam

2012-01-01

In order to better understand the emergence of chronic non-communicable diseases in low- and middle-income countries this article seeks to present, in context, different transitional processes which societies and populations are currently undergoing. Relevant factors for specific contexts such as Peru are described, including internal migration, urbanization and profiles of adversity in early life, all of them linked to chronic non-communicable diseases, including obesity and overweight. The capacity-load model, which considers chronic disease risk in adulthood as a function of two generic traits, metabolic capacity and metabolic load, is described. The contribution of rural-to-urban migration to this problem is also presented. Finally, these topics are framed within pending challenges for public health in Peru.

The effect on cardiovascular risk factors of migration from rural to urban areas in Peru: PERU MIGRANT Study

Miranda, J Jaime; Gilman, Robert H; García, Héctor H; Smeeth, Liam

2009-01-01

Background Mass-migration observed in Peru from the 1970s occurred because of the need to escape from politically motivated violence and work related reasons. The majority of the migrant population, mostly Andean peasants from the mountainous areas, tends to settle in clusters in certain parts of the capital and their rural environment could not be more different than the urban one. Because the key driver for migration was not the usual economic and work-related reasons, the selection effects whereby migrants differ from non-migrants are likely to be less prominent in Peru. Thus the Peruvian context offers a unique opportunity to test the effects of migration. Methods/Design The PERU MIGRANT (PEru's Rural to Urban MIGRANTs) study was designed to investigate the magnitude of differences between rural-to-urban migrant and non-migrant groups in specific CVD risk factors. For this, three groups were selected: Rural, people who have always have lived in a rural environment; Rural-urban, people who migrated from rural to urban areas; and, Urban, people who have always lived in a urban environment. Discussion Overall response rate at enrolment was 73.2% and overall response rate at completion of the study was 61.6%. A rejection form was obtained in 282/323 people who refused to take part in the study (87.3%). Refusals did not differ by sex in rural and migrant groups, but 70% of refusals in the urban group were males. In terms of age, most refusals were observed in the oldest age-group (>60 years old) in all study groups. The final total sample size achieved was 98.9% of the target sample size (989/1000). Of these, 52.8% (522/989) were females. Final size of the rural, migrant and urban study groups were 201, 589 and 199 urban people, respectively. Migrant's average age at first migration and years lived in an urban environment were 14.4 years (IQR 10–17) and 32 years (IQR 25–39), respectively. This paper describes the PERU MIGRANT study design together with a critical analysis of the potential for bias and confounding in migrant studies, and strategies for reducing these problems. A discussion of the potential advantages provided by the case of migration in Peru to the field of migration and health is also presented. PMID:19505331

Lincoln, Alisa K.; White, Andrew; Aldsworth, Casandra; Johnson, Peggy; Strunin, Lee

2010-01-01

Staff in the psychiatric emergency room (PER) have demanding jobs requiring a complex balance between the needs and safety of the individual and the community, systemic resources, and job responsibilities while providing timely, effective care. Little research exists concerning day-to-day work activities of PER staff, their interaction, and their perceptions of their work. This study explored the work of PER staff and the organisational context of the PER work setting. Observations of staff were conducted in the public spaces of a public urban PER using two observational techniques. The first was designed to measure the types of work activities staff engaged in and the time spent in these work activities (work task data). The second technique was the gathering of observational data by a peripheral-member-researcher (participant observation data). Analyses were conducted of both the work task and participant observation data. Results indicate that most PER staff time is spent in administrative and phone tasks, while less than a third is spent on direct clinical work. Four important issues for PER work were identified: a workload that is unmanageable, managing the unmanageable, bogus referrals and dumping and insurance problems. The PER remains the front-line of the medical and social service systems. Work done in these settings is of critical importance; however little attention is paid to the content and nature of the work. Our study demonstrates that staff of the PER face challenges on many levels as they struggle with the task of working with people presenting in psychiatric and social crisis. PMID:20149148

Despite decades of work in environmental science and ecology, estimating human influences on ecosystems remains challenging. This is partly due to complex chains of causation among ecosystem elements, exacerbated by the difficulty of collecting biological data at sufficient spatial, temporal, and taxonomic scales. Here, we demonstrate the utility of environmental DNA (eDNA) for quantifying associations between human land use and changes in an adjacent ecosystem. We analyze metazoan eDNA sequences from water sampled in nearshore marine eelgrass communities and assess the relationship between these ecological communities and the degree of urbanization in the surrounding watershed. Counter to conventional wisdom, we find strongly increasing richness and decreasing beta diversity with greater urbanization, and similar trends in the diversity of life histories with urbanization. We also find evidence that urbanization influences nearshore communities at local (hundreds of meters) rather than regional (tens of km) scales. Given that different survey methods sample different components of an ecosystem, we then discuss the advantages of eDNA-which we use here to detect hundreds of taxa simultaneously-as a complement to traditional ecological sampling, particularly in the context of broad ecological assessments where exhaustive manual sampling is impractical. Genetic data are a powerful means of uncovering human-ecosystem interactions that might otherwise remain hidden; nevertheless, no sampling method reveals the whole of a biological community.

Professional development strategies for teaching urban biology teachers to use concept maps effectively

NASA Astrophysics Data System (ADS)

McGregor Petgrave, Dahlia M.

Many teachers are not adequately prepared to help urban students who have trouble understanding conceptual ideas in biology because these students have little connection to the natural world. This study explored potential professional development strategies to help urban biology teachers use concept maps effectively with various topics in the biology curriculum. A grounded theory approach was used to develop a substantive professional development model for urban biology teachers. Qualitative data were collected through 16 semi-structured interviews of professional developers experienced in working with concept maps in the urban context. An anonymous online survey was used to collect quantitative data from 56 professional developers and teachers to support the qualitative data. The participants were from New York City, recruited through the NY Biology-Chemistry Professional Development Mentor Network and the NY Biology Teachers' Association. According to the participants, map construction, classroom applications, lesson planning, action research, follow-up workshops, and the creation of learning communities are the most effective professional development strategies. The interviewees also proposed English language learning strategies such as picture maps, native word maps, and content reading materials with underlined words. This study contributes to social change by providing a professional development model to use in planning workshops for urban teachers. Urban teachers improve their own conceptual understanding of biology while learning how to implement concept mapping strategies in the classroom. Students whose teachers are better prepared to teach biology in a conceptual manner have the potential of growing into more scientifically literate citizens.

Catchment Dispersion Mechanisms in an Urban Context

NASA Astrophysics Data System (ADS)

Gironas, J. A.; Mejia, A.; Rossel, F.; Rinaldo, A.; Rodriguez, F.

2014-12-01

Dispersion mechanisms have been examined in-depth in natural catchments in previous studies. However, these dispersion mechanisms have been studied little in urban catchments, where artificial transport elements and morphological arrangements are expected to modify travel times and mobilize excess rainfall from spatially distributed impervious sites. Thus, these features can modify the variance of the catchment's travel times and hence the total dispersion. This work quantifies the dispersion mechanisms in an urban catchment using the theory of transport by travel times as represented by the Urban Morpho-climatic Instantaneous Unit Hydrograph (U-McIUH) model. This model computes travel times based on kinematic wave theory and accounts explicitly for the path heterogeneities and altered connectivity patterns characteristic of an urban drainage network. The analysis is illustrated using the Aubinière urban catchment (France) as a case study. We found that kinematic dispersion is dominant for small rainfall intensities, whereas geomorphologic dispersion becomes more dominant for larger intensities. The total dispersion scales with the drainage area in a power law fashion. The kinematic dispersion is dominant across spatial scales up to a threshold of approximately 2-3 km2, after which the geomorphologic dispersion becomes more dominant. Overall, overland flow is responsible for most of the dispersion, while conduits tend to counteract the increase of the geomorphologic dispersion with a negative kinematic dispersion. Further studies with other catchments are needed to assess whether the latter is a general feature of urban drainage networks.

Squatting and urban renewal: the interaction of squatter movements and strategies of urban restructuring in Berlin.

PubMed

Holm, Andrej; Kuhn, Armin

2011-01-01

Squatting as a housing strategy and as a tool of urban social movements accompanies the development of capitalist cities worldwide. We argue that the dynamics of squatter movements are directly connected to strategies of urban renewal in that movement conjunctures occur when urban regimes are in crisis. An analysis of the history of Berlin squatter movements, their political context and their effects on urban policies since the 1970s, clearly shows how massive mobilizations at the beginning of the 1980s and in the early 1990s developed in a context of transition in regimes of urban renewal. The crisis of Fordist city planning at the end of the 1970s provoked a movement of "rehab squatting" ('Instandbesetzung'), which contributed to the institutionalization of "cautious urban renewal" ('behutsame Stadterneuerung') in an important way. The second rupture in Berlin's urban renewal became apparent in 1989 and 1990, when the necessity of restoring whole inner-city districts constituted a new, budget-straining challenge for urban policymaking. Whilst in the 1980s the squatter movement became a central condition for and a political factor of the transition to "cautious urban renewal," in the 1990s large-scale squatting — mainly in the eastern parts of the city — is better understood as an alien element in times of neoliberal urban restructuring.

Global literature has suggested a potential negative impact of social stigma on both physical and mental health among those who are being stigmatized. However, limited data are available regarding the form of stigma and stigmatization against rural-to-urban migrant workers in developing countries, including China. This study, employing qualitative data collected from focus group discussions and in-depth individual interviews with rural-to-urban migrants in Beijing, China, was designed to understand the forms and context of stigmatization against rural migrant workers. The data in the current study show that rural-to-urban migrant workers in China had experienced various forms of stigmatization including labelling, stereotyping, separation, status loss and discrimination. Stigmatization occurred through different contexts of migrant workers' lives in urban destinations, including employment seeking, workplace benefits, and access to health and other public services. The current study is a necessary first step to assess the potential impact of stigmatization on both the physical and psychological well-being of rural-to-urban migrant workers.

2016-01-01

This article analyzes the relations between mental health and well-being in urban and rural contexts marked by poverty. The analysis takes as its basis a quantitative research conducted with 417 adult inhabitants of two communities, one rural and the other urban, in Northeastern Brazil. The data were constructed using questionnaires composed of sociodemographic data, the Personal Wellbeing Index and Self Report Questionnaire (SRQ-20) scales. We found significant differences between the inhabitants of the rural and urban communities regarding well-being and the prevalence of common mental disorders (CMD), with a higher average well-being score in the rural context; the urban sample had a higher average regarding the prevalence of CMD. The variable income significantly influenced the SRQ-20 average scores; the same was not observed with well-being scores. Besides, it was observed that there is a negative correlation with well-being and CMD.

Effects of heat stress on working populations when facing climate change.

It is accepted that the earth's climate is changing in an accelerating pace, with already documented implications for human health and the environment. This literature review provides an overview of existing research findings about the effects of heat stress on the working population in relation to climate change. In the light of climate change adaptation, the purpose of the literature review was to explore recent and previous research into the impacts of heat stress on humans in an occupational setting. Heat stress in the workplace has been researched extensively in the past however, in the contemporary context of climate change, information is lacking on its extent and implications. The main factors found to exacerbate heat stress in the current and future workplace are the urban 'heat island effect', physical work, individual differences, and the developing country context where technological fixes are often not applicable. There is also a lack of information on the effects on vulnerable groups such as elderly people and pregnant women. As increasing temperatures reduce work productivity, world economic productivity could be condensed, affecting developing countries in the tropical climate zone disproportionately. Future research is needed taking an interdisciplinary approach, including social, economic, environmental and technical aspects.

'The vagina does not talk': conception concealed or deliberately disclosed in eastern Cameroon.

PubMed

van der Sijpt, Erica

2012-01-01

In the East Province of Cameroon, respectable womanhood has long been intrinsically related to ethics of production and reproduction: women attain social standing through productive work in the fields and through the reproduction of children - preferably within a marital setting. Yet, in the face of current alternative 'horizons of honour' such as schooling, employment or relationships with rich urban men, women's intentions with regard to marriage and motherhood acquire different meanings. On their pathways to urban forms of honour, formal engagements and childbearing are often postponed, while premarital sexual encounters proliferate. This paper explores the meanings of pregnancy within the context of these fragile relationships and women's urban aspirations; fertility will be shown to be a 'bet' that may either disrupt or stabilize urban affairs and ambitions. As such, pregnancies can be strategically anticipated and deliberately disclosed or unexpectedly encountered and secretly disrupted. This paper sheds light on women's strategies of concealment and disclosure of pregnancies and shows that these practices are often inspired by a notion of the 'right timing' of particular reproductive conjunctures - a notion that is of increasing relevance in current frames of female honour in Cameroon.

Modeling and managing urban water demand through smart meters: Benefits and challenges from current research and emerging trends

NASA Astrophysics Data System (ADS)

Cominola, A.; Giuliani, M.; Castelletti, A.; Piga, D.; Rizzoli, A. E.

2015-12-01

Urban population growth, climate and land use change are expected to boost residential water demand in urban contexts in the next decades. In such a context, developing suitable demand-side management strategies is essential to meet future water demands, pursue water savings, and reduce the costs for water utilities. Yet, the effectiveness of water demand management strategies (WDMS) relies on our understanding of water consumers' behavior, their consumption habits, and the water use drivers. While low spatial and temporal resolution water consumption data, as traditionally gathered for billing purposes, hardly support this understanding, the advent of high-resolution, smart metering technologies allowed for quasi real-time monitoring water consumption at the single household level. This, in turn, is advancing our ability in characterizing consumers' behavior, modeling, and designing user-oriented residential water demand management strategies. Several water smart metering programs have been rolled-out in the last two decades worldwide, addressing one or more of the following water demand management phases: (i) data gathering, (ii) water end-uses characterization, (iii) user modeling, (iv) design and implementation of personalized WDMS. Moreover, the number of research studies in this domain is quickly increasing and big economic investments are currently being devoted worldwide to smart metering programs. With this work, we contribute the first comprehensive review of more than 100 experiences in the field of residential water demand modeling and management, and we propose a general framework for their classification. We revise consolidated practices, identify emerging trends and highlight the challenges and opportunities for future developments given by the use of smart meters advancing residential water demand management. Our analysis of the status quo of smart urban water demand management research and market constitutes a structured collection of information supporting the development of integrated procedures in the field of urban water management, as well as common actions aiding the collaboration with other sectors, as the nexus with energy demand management.

London 2012: occupational health in the construction programme.

PubMed

Waterman, Lawrence

2007-05-01

This article explores the approach to occupational health in the UK construction industry in both broad and narrow contexts. The construction programme for the 2012 Olympic Games and Paralympic Games includes the creation of a large urban park in east London containing many sports venues and served by enhanced infrastructure. The Olympic Delivery Authority (ODA), responsible for the construction programme, is developing plans that seek to assure the health of the thousands of workers who will be engaged in this work. Such plans are not being drafted in a vacuum. In addition to considerable consultation with stakeholders the ODA is also drawing on some of the exciting work that has been undertaken in occupational health in recent years. In particular, the move from a focus on technical health services provided by 'experts' to an acceptance that health issues should be managed within employing organizations. Understanding this broad context provides a solid basis for analysing the specific proposals for occupational support during the Olympic Park construction.

Urban Options for Psychological Restoration: Common Strategies in Everyday Situations.

Staats, Henk; Jahncke, Helena; Herzog, Thomas R; Hartig, Terry

2016-01-01

Given the need for knowledge on the restorative potential of urban settings, we sought to estimate the effects of personal and contextual factors on preferences and restoration likelihood assessments for different urban activities-in-environments. We also sought to study the generality of these effects across different countries. We conducted a true experiment with convenience samples of university students in the Netherlands (n = 80), Sweden (n = 100), and the USA (n = 316). In each country, the experiment had a mixed design with activities-in-environments (sitting in a park, sitting in a cafe, walking in a shopping mall, walking along a busy street) manipulated within-subjects and the need for restoration (attentional fatigue, no attentional fatigue) and immediate social context (in company, alone) manipulated between-subjects. The manipulations relied on previously tested scenarios describing everyday situations that participants were instructed to remember and imagine themselves being in. For each imagined situation (activity-in-environment with antecedent fatigue condition and immediate social context), subjects provided two criterion measures: general preference and the likelihood of achieving psychological restoration. The settings received different preference and restoration likelihood ratings as expected, affirming that a busy street, often used in comparisons with natural settings, is not representative of the restorative potential of urban settings. Being with a close friend and attentional fatigue both moderated ratings for specific settings. Findings of additional moderation by country of residence caution against broad generalizations regarding preferences for and the expected restorative effects of different urban settings. Preferences and restoration likelihood ratings for urban activity-environment combinations are subject to multiple personal and contextual determinants, including level of attentional fatigue, being alone versus in company, and broader aspects of the urban context that vary across cities and countries. Claims regarding a lack of restorative quality in urban environments are problematic.

Mosses are useful, ubiquitous accumulation biomonitors and as such can be used for biomonitoring surveys. However, the biomonitoring of atmospheric pollution can be compromised in urban contexts if the targeted biomonitors are regularly disturbed, irregularly distributed, or are difficult to access. Here, we test the hypothesis that cemeteries are appropriate moss sampling sites for the evaluation of air pollution in urban areas. We sampled mosses growing on gravestones in 21 urban and peri-urban cemeteries in the Paris metropolitan area. We focused on Grimmia pulvinata (Hedwig) Smith, a species abundantly found in all studied cemeteries and very common in Europe. The concentration of Al, As, Br, Ca, Ce, Cl, Cr, Cu, Fe, K, Mn, Ni, V, P, Pb, Rb, S, Sr, Ti, and Zn was determined by a total reflection X-ray fluorescence technique coupled with a slurry sampling method (slurry-TXRF). This method avoids a digestion step, reduces the risk of sample contamination, and works even at low sample quantities. Elemental markers of road traffic indicated that the highest polluted cemeteries were located near the highly frequented Parisian ring road and under the influence of prevailing winds. The sites with the lowest pollution were found not only in the peri-urban cemeteries, adjoining forest or farming landscapes, but also in the large and relatively wooded cemeteries located in the center of Paris. Our results suggest that (1) slurry-TXRF might be successfully used with moss material, (2) G. pulvinata might be a good biomonitor of trace metals air pollution in urban context, and (3) cemetery moss sampling could be a useful complement for monitoring urban areas. Graphical abstract We tested the hypothesis that cemeteries are appropriate moss sampling sites for the evaluation of air pollution in urban areas. We sampled 110 moss cushions (Grimmia pulvinata) growing on gravestones in 21 urban and peri-urban cemeteries in the Paris metropolitan area. The concentration of 20 elements in mosses was determined by a total reflection X-ray fluorescence technique coupled with a slurry sampling method. Statistical analysis revealed that: - Urbanized Parisian areas crossed by traffic roads have the highest polluted cemeteries with a strong influence of main wind direction on the distribution of air pollutants - As expected, small cemeteries with low tree density were heavily polluted - Less obvious, large green spaces such as large cemeteries (Père Lachaise, Montmartre, Montparnasse) in the center of a dense metropolis like Paris present the same level of atmospheric trace metal pollution as cemeteries in less urbanized areas or nearing a very large forest. This suggests that even in densely urbanized areas, there is more spatial variability in pollution distribution than usually assumed and that large urban areas with low traffic and green filters such as trees are likely to intercept air pollutants.

The framework of urban exposome: Application of the exposome concept in urban health studies.

Andrianou, Xanthi D; Makris, Konstantinos C

2018-05-02

Horizontal challenges, such as climate change or the growing populations, and their manifestations require the development of multidisciplinary research synergies in urban health that could benefit from concepts, such as the human exposome. Cities are composed of interconnected systems which are influenced, by global trends, national policies and local complexities. In this context, the exposome concept could be expanded having the city setting in its core, providing the conceptual framework for the new generation of urban studies. The objectives of this work were to define the urban exposome and outline its utility. The urban exposome can be defined as the continuous spatiotemporal surveillance/monitoring of quantitative and qualitative indicators associated with the urban external and internal domains that shape up the quality of life and the health of urban populations, using small city areas, i.e. neighborhoods, quarters, or smaller administrative districts, as the point of reference. Research should focus on the urban exposome's measurable units at different levels, i.e. the individuals, small, within-city areas and the populations. The urban exposome framework applied in the city of Limassol, Cyprus combines three elements: (i) a mixed-methods study on stakeholders' opinions about quality of life in the city; (ii) a systematic assessment of secondary data from the cancer and death registries, including city infrastructure data; and (iii) a population health and biomonitoring survey. Continuous assessment of environmental and health indicators that are routinely collected, and the incorporation of primary data from population studies, will allow for the timely identification of within-city health and environmental disparities to inform policy making and public health interventions. The urban exposome could facilitate evidence-based public health response, offering researchers, policy-makers, and citizens effective tools to address the societal needs of large urban centers.

The aim of this paper is to understand the sustainability of urban spatial transformation in the process of rapid urbanization, and calls for future research on the demographic and economic dimensions of climate change. Shanghai towards its transformation to a metropolis has experienced vast socioeconomic and ecological change and calls for future research on the impacts of demographic and economic dimensions on climate change. We look at the major questions (1) to explore economic and demographic growth, land use and land-cover changes in the context of rapid economic and city growth, and (2) to analyze how the demography and economic growth have been associated with the local air temperature and vegetation. We examine urban growth, land use and land-cover changes in the context of rapid economic development and urbanization. We assess the impact of urban expansion on local air temperature and vegetation. The analysis is based on time series data of land use, normalized difference vegetation index (NDVI), and meteorological, demographic and economic data. The results indicate that urban growth has been driven by mass immigration; as a consequence of economic growth and urban expansion, a large amount of farmland has been converted to paved road and residential buildings. Furthermore, the difference between air temperature in urban and exurban areas has increased rapidly. The decrease of high mean annual NDVI has mainly occurred around the dense urban areas.

Dynamic linkages between road transport energy consumption, economic growth, and environmental quality: evidence from Pakistan.

PubMed

Danish; Baloch, Muhammad Awais

2018-03-01

The focus of the present research work is to investigate the dynamic relationship between economic growth, road transport energy consumption, and environmental quality. To this end, we rely on time series data for the period 1971 to 2014 in the context of Pakistan. To use sulfur dioxide (SO 2 ) emission from transport sector as a new proxy for measuring environmental quality, the present work employs time series technique ARDL which allows energy consumption from the transport sector, urbanization, and road infrastructure to be knotted by symmetric relationships with SO 2 emissions and economic growth. From the statistical results, we confirm that road infrastructure boosts economic growth. Simultaneously, road infrastructure and urbanization hampers environmental quality and causes to accelerate emission of SO 2 in the atmosphere. Furthermore, economic growth has a diminishing negative impact on total SO 2 emission. Moreover, we did not find any proof of the expected role of transport energy consumption in SO 2 emission. The acquired results directed that care should be taken in the expansion of road infrastructure and green city policies and planning are required in the country.

Exploring Child Mortality Risks Associated with Diverse Patterns of Maternal Migration in Haiti

Smith-Greenaway, Emily; Thomas, Kevin

2014-01-01

Internal migration is a salient dimension of adulthood in Haiti, particularly among women. Despite the prevalence of migration in Haiti, it remains unknown whether Haitian women’s diverse patterns of migration influence their children’s health and survival. In this paper, we introduce the concept of lateral (i.e., rural-to-rural, urban-to-urban) versus nonlateral (i.e., rural-to-urban, urban-to-rural) migration to describe how some patterns of mothers’ internal migration may be associated with particularly high mortality among children. We use the 2006 Haitian Demographic and Health Survey to estimate a series of discrete-time hazard models among 7,409 rural children and 3,864 urban children. We find that, compared with their peers with nonmigrant mothers, children born to lateral migrants generally experience lower mortality whereas those born to nonlateral migrants generally experience higher mortality. Although there are important distinctions across Haiti’s rural and urban contexts, these associations remain net of socioeconomic factors, suggesting they are not entirely attributable to migrant selection. Considering the timing of maternal migration uncovers even more variation in the child health implications of maternal migration; however, the results counter the standard disruption and adaptation perspective. Although future work is needed to identify the processes underlying the differential risk of child mortality across lateral versus nonlateral migrants, the study demonstrates that looking beyond rural-to-urban migration and considering the timing of maternal migration can provide a fuller, more complex understanding of migration’s association with child health.

The Innovation Deficit in Urban Water: The Need for an Integrated Perspective on Institutions, Organizations, and Technology.

Kiparsky, Michael; Sedlak, David L; Thompson, Barton H; Truffer, Bernhard

Interaction between institutional change and technological change poses important constraints on transitions of urban water systems to a state that can meet future needs. Research on urban water and other technology-dependent systems provides insights that are valuable to technology researchers interested in assuring that their efforts will have an impact. In the context of research on institutional change, innovation is the development, application, diffusion, and utilization of new knowledge and technology. This definition is intentionally inclusive: technological innovation will play a key role in reinvention of urban water systems, but is only part of what is necessary. Innovation usually depends on context, such that major changes to infrastructure include not only the technological inventions that drive greater efficiencies and physical transformations of water treatment and delivery systems, but also the political, cultural, social, and economic factors that hinder and enable such changes. On the basis of past and present changes in urban water systems, institutional innovation will be of similar importance to technological innovation in urban water reinvention. To solve current urban water infrastructure challenges, technology-focused researchers need to recognize the intertwined nature of technologies and institutions and the social systems that control change.

Roads as sources of heavy metals in urban areas. The Covões Catchment experiment, Coimbra, Portugal

2015-04-01

Cities are the home to 50% of the human specie [UN 2011 Ramalho & Hobbs 2012], whose wellbeing, way of life and exposure to hazard situations are directly related to the built environment. Cities are often seen as ecological systems just a short step away from collapse [Newman 2006]. Being a human construction, cities disrupt the natural cycles and the patterns of temporal and spatial distribution of environmental and ecological processes. Urbanization produces ruptures in biota, water, energy and nutrients connectivity that can lead to an enhanced exposure to disruptive events that hamper the wellbeing and the resilience of urban communities in a global change context. A major issue in what concerns the threats to human and ecosystem health in urban areas is the presence of heavy metals, and the related processes that govern their source, transport and fade r uptake by the vegetation. In this work, we present an analysis of heavy metal sources and transport processes at various types of roads within the Ribeira dos Covões peri-urban experimental catchment in central Portugal. The surveyed heavy metals (Cadmium, Lead, Coper, and Zinc) show significant differences as a result of the type of rainfall event, the length of the antecedent dry spell, the traffic volume and the heavy metals sources. For some locations, namely for the roads with heavy traffic volume, the heavy metal concentrations exceed the limits established by law, which has severe implications to the downstream ecosystems and to the possible use of the water from roads to close the resources loop in urban areas, namely in what concerns their use to water the urban green infrastructure or to irrigate the urban agriculture fields.

Is eating science or common sense? Knowledge about "natural foods" among self-identified "natural food" consumers, vendors and producers in rural and urban Mexico.

PubMed

Kooijmans, Anneke; Flores-Palacios, Fátima

2014-10-01

To explore the common sense knowledge that consumers, vendors and producers hold of "natural foods". The focus was on common knowledge because this is infrequently explored in social psychology where most studies focus on the implementation of scientific knowledge. The focus was on natural foods because the naturalness of foods seems to be one of the particular concerns that current consumers have about today's food market and because a specific natural food preference was observed in the contexts of study. Fifty-seven informants in a rural context and 58 informants in an urban context participated in either a free association study or an interview study. Data content were analyzed. In the urban context natural foods obtain their significance in the relationship between food and the self-concept; eating natural (or good) food is a task that requires effort and attitude, and foods obtain a moral value. In the rural context natural foods obtain their significance as an expression of a social and cultural system of interdependence that establishes practices and customs that have a long history in the community. It is suggested that these common knowledge systems are related to practical challenges that are particular to the informants' context and that the structure of their common sense knowledge systems depend on the mediation of the flow of scientific knowledge and technological knowledge in each context.

Decentralized peri-urban wastewater treatment technologies assessment integrating sustainability indicators.

PubMed

Mena-Ulecia, Karel; Hernández, Heykel Hernández

2015-01-01

Selection of treatment technologies without considering the environmental, economic and social factors associated with each geographical context risks the occurrence of negative impacts that were not properly foreseen, working against the sustainable performance of the technology. The principal aim of this study was to evaluate 12 technologies for decentralized treatment of domestic wastewater applicable to peri-urban communities using sustainability approaches and, at the same time, continuing a discussion about how to address a more integrated assessment of overall sustainability. For this, a set of 13 indicators that embody the environmental, economic and social approach for the overall sustainability assessment were used by means of a target plot diagram as a tool for integrating indicators that represent a holistic analysis of the technologies. The obtained results put forward different degrees of sustainability, which led to the selection of: septic tank+land infiltration; up-flow anaerobic reactor+high rate trickling filter and septic tank+anaerobic filter as the most sustainable and attractive technologies to be applied in peri-urban communities, according to the employed indicators.

Closing the poor-rich gap in contraceptive use in urban Kenya: are family planning programs increasingly reaching the urban poor?

2013-08-27

Kenya is characterized by high unmet need for family planning (FP) and high unplanned pregnancy, in a context of urban population explosion and increased urban poverty. It witnessed an improvement of its FP and reproductive health (RH) indicators in the recent past, after a period of stalled progress. The objectives of the paper are to: a) describe inequities in modern contraceptive use, types of methods used, and the main sources of contraceptives in urban Kenya; b) examine the extent to which differences in contraceptive use between the poor and the rich widened or shrank over time; and c) attempt to relate these findings to the FP programming context, with a focus on whether the services are increasingly reaching the urban poor. We use data from the 1993, 1998, 2003 and 2008/09 Kenya demographic and health survey. Bivariate analyses describe the patterns of modern contraceptive use and the types and sources of methods used, while multivariate logistic regression models assess how the gap between the poor and the rich varied over time. The quantitative analysis is complemented by a review on the major FP/RH programs carried out in Kenya. There was a dramatic change in contraceptive use between 2003 and 2008/09 that resulted in virtually no gap between the poor and the rich in 2008/09, by contrast to the period 1993-1998 during which the improvement in contraceptive use did not significantly benefit the urban poor. Indeed, the late 1990s marked the realization by the Government of Kenya and its development partners, of the need to deliberately target the poor with family planning services. Most urban women use short-term and less effective methods, with the proportion of long-acting method users dropping by half during the review period. The proportion of private sector users also declined between 2003 and 2008/09. The narrowing gap in the recent past between the urban poor and the urban rich in the use of modern contraception is undoubtedly good news, which, coupled with the review of the family program context, suggests that family planning programs may be increasingly reaching the urban poor.

Patterns of productive activity engagement among older adults in urban China.

Liu, Huiying; Lou, Wei Qun

2016-12-01

This study aims to identify patterns of productive activity engagement among older adults in urban China. Once patterns are identified, we further explore how a set of individual characteristics is associated with these patterns. Using data from the 2011 baseline survey of the China Health and Retirement Longitudinal Study (CHARLS), we performed a latent class analysis (LCA) on a national representative sample of adults aged 60 years and over ( N  = 3019). A specified range of productive activity indicators that fit the context of urban China was used for performing LCA (including working, grandchildren's care, parental care, spousal care, informal helping, and formal volunteering). A multinomial logistic regression was used to assess whether individual characteristics are associated with the identified patterns. The results indicated that a four-class model fit the data well, with the interpretable set of classes: spouse carer (51.2 %), working grandparents (21.7 %), multifaceted contributor (16.6 %), and light-engaged volunteer (10.5 %). Age, gender, education, number of children, proximity with the nearest child, household composition and functional status contributed to differentiating these classes. This study captured the reality of productive engagement among older adults by drawing attention to how multiple productive activities intersect in later-life stages. Our findings have implications for policy-makers, health care practitioners, and community advocates to develop programs that facilitate this aging population in assuming meaningful productive activities.

Developing Eastern Africa's resilience to flood and drought through multi-functional ecosystem-based management strategies

NASA Astrophysics Data System (ADS)

Lyon, Steve W.

2017-04-01

The rapid urbanization and agricultural expansion of Eastern Africa puts people in direct conflict with nature. Nowhere is this more obvious than for water resources where the delicate balance of too much water (flood) or too little water (drought) is a matter of life and death for millions. This work tackles this apparent conflict head-on by considering ecosystem service trade-offs relevant for water-based disasters as populations transition from rural to more intensive agricultural/urban lifestyles. Specifically, recent work from the Kilombero Valley of Tanzania, a region which has been targeted for development investment but where potential impacts (not to mention sustainability) associated with various development scenarios remain largely unresolved, will be presented as relevant case study. Our efforts on modelling and data synthesis for this region have shown promise as we seek to advance science in more and more remote (and in particular developing) regions while allowing important improvements for management of less and less available resources. Thus, in spite of large uncertainties the work highlights how research may still provide an improved system understanding of resource flows even when working under less than perfect conditions. Subsequently, such understanding feeds into development of frameworks for quantifying socio-hydrological impacts of land-water management. To ensure relevance regionally, we consider Kilombero Valley in the context of existing nature-based approaches dealing with disaster risk reduction. Such context potentially facilitates transfer of knowledge across country borders. Our goal here is to empower planners and stakeholders throughout the region by helping translate their knowledge into optimized adaptation strategies and linking their experiences through South-South transfer. There remains an open (and fundamental) question of how to best define management recommendations and activities that not only achieve climate resiliency but also are acceptable for stakeholders without compromising ecosystem service supplies.

A social ecological assessment of physical activity among urban adolescents.

Yan, Alice Fang; Voorhees, Carolyn C; Beck, Kenneth H; Wang, Min Qi

2014-05-01

To examine the physical, social and temporal contexts of physical activity, as well as sex variations of the associations among 314 urban adolescents. Three-day physical activity recall measured contextual information of physical activities. Logistic regressions and generalized estimating equation models examined associations among physical activity types and contexts, and sex differences. Active transportation was the most common physical activity. Home/neighborhood and school were the most common physical activity locations. School was the main location for organized physical activity. Boys spent more time on recreational physical activity, regardless of the social context, compared to girls. The average physical activity level was significantly lower for girls than for boys after school. Physical activity promotion interventions need to target physical activity environments and social contexts in a sex-specific manner.

Does it pay to have a network contact? Social network ties, workplace racial context, and pay outcomes.

PubMed

Kmec, Julie A; Trimble, Lindsey B

2009-06-01

This article investigates how social network use to find work affects pay. Analyses using the Multi-City Study of Urban Inequality consider the extent to which a network contact's influence level affects a job applicant's pay, whether this effect differs for white, black, and Latino contacts, and how workplace racial context moderates this relationship. Three main findings emerge. First, having an influential contact--one with hiring authority--compared to having no contact yields higher pay. Second, white and minority contact influence on pay differs: among minority contacts, being an outsider (i.e., someone not employed by the firm to which the applicant applies) is associated with higher pay, but being an employee of the firm--an insider--is not. Third, regardless of workplace racial context, black and Latino contacts' influence is most beneficial when their race/ethnicity is not known to the hiring agent. We offer a new interpretation of the mixed findings with regard to the relationship between social network use and pay.

This case study examines an arts organization at the center of an urban neighborhood revitalization effort and its contributions to creative placemaking and inclusive community building. The study documents innovative arts practices and explores their meaning for a local context, an understudied city in the Mid-South region of the United States. It builds on the research team's ongoing work as teachers, students, and scholars in partnership with the arts organization. It includes systematic participant observation, interviews with stakeholders, and a review of historical and contemporary media coverage. We found that the organization and its practices provided a rich context for exploring an expanded sense of community including bridging social capital and place-based frameworks. Analysis suggests that the organization's intentional arts based practices bring multiple understandings of community and art into meaningful dialogue through the generation of creative and social friction. These practices illustrate one context-specific strategy addressing the tensions in a community-diversity dialectic (Townley et al. in Am J Commun Psychol 47:69-85, 2011).

Yes, but for that we need star parks and lighting specialists as partners.Educational aspectThe citizens must be able to identify the planets, constellations and other celestial objects in their urban residence. This is part of a basic education. The number of the people living in the urban area who never see the main constellations or important stars increase every year. We must do something for our urban community.What is an urban star park?An urban public park where we can see the main constellations can be considered an urban star park. There can be organized a lot of activities as practical lessons of astronomy, star parties, etc.Classification of the urban star parksA proposal for classification of the urban star parks taking in consideration the quality of the sky and the number of the city inhabitants:Two categories:- city star parks for cities with < 100.000 inhabitants- metropolis star parks for cities with > 100.000 inhabitantsFive levels of quality:- 1* level = can see stars of at least 1 magnitude with the naked eyes- 2* level = at least 2 mag- 3* level = at least 3 mag- 4* level= at least 4 mag- 5* level = at least 5 magThe urban star urban park structure and lighting systemA possible structure of a urban star park and sky-friend lighting including non-electric illumination are descripted.The International Commission on IlluminationA description of this structure which has as members national commissions from all over the world.Dark-sky activists - lighting specialistsNational Commissions on Illumination organize courses of lighting specialist. Dark-sky activists can become lighting specialists. The author shows his experience in this aspect as a recent lighting specialist and his cooperation with the Romanian National Commission on Illumination working for a law of illumination in Romania and to implement the sky protection elements into the lighting specialist accreditation.

Urban Resources Selection and Allocation for Emergency Shelters: In a Multi-Hazard Environment.

PubMed

Chen, Wei; Zhai, Guofang; Ren, Chongqiang; Shi, Yijun; Zhang, Jianxin

2018-06-14

This study explores how emergency shelters can adapt to a multi-hazard environment by geographic information system (GIS) and takes Guangzhou as a case for analysis. The physical suitability of the overall urban resources was first assessed by aiming to select the suitable resources and safe locations for emergency shelters in the context of multiple disasters. Afterward, by analyzing the scale and spatial distribution of affected areas and populations under different types of disaster scenarios, the demand for different kinds of shelters were predicted. Lastly, taking into account the coverage of the affected people, shelters were allocated according to different conditions in the districts. This work will hopefully provide a reference for the construction of emergency shelters and help form emergency operations in order to mitigate the impact of hazards. The issues identified in the study need to be further studied in medium or small-scale cities.

Ghannem, H; Hadj Fredj, A

1997-12-01

With the epidemiological transition phenomenon, Tunisia is now facing the growing prevalence of chronic diseases. Environmental and behavioural changes such as the adoption of new dietary habits and a sedentary lifestyle, and the stress of urbanization and of working conditions all lead to the rise in cardiovascular disease (CVD) risk factors. The aim of this study is to estimate the prevalence of the main CVD risk factors in an urban context. For this, we have undertaken a household epidemiological survey of a representative sample of the adult urban population of Soussa, Tunisia (n = 957). This study shows high prevalences of hypertension (blood pressure >160/95 mmHg) of 18.8 per cent with an adjusted rate of 15.6 per cent, history of diabetes of 10.2 per cent, and obesity (body mass index > 30) of 27.7 per cent [significantly higher in women (34.4 per cent)], android obesity 36 per cent, smoking habits 21.5 per cent [significantly higher in men (61.4 per cent)]. With this profile of CVD risk factors, Tunisia must implement a national strategy of primary prevention and heart health promotion in addition to the efforts recently made in secondary prevention of some chronic diseases such as hypertension and diabetes.

Comparison of sampling strategies for object-based classification of urban vegetation from Very High Resolution satellite images

NASA Astrophysics Data System (ADS)

Rougier, Simon; Puissant, Anne; Stumpf, André; Lachiche, Nicolas

2016-09-01

Vegetation monitoring is becoming a major issue in the urban environment due to the services they procure and necessitates an accurate and up to date mapping. Very High Resolution satellite images enable a detailed mapping of the urban tree and herbaceous vegetation. Several supervised classifications with statistical learning techniques have provided good results for the detection of urban vegetation but necessitate a large amount of training data. In this context, this study proposes to investigate the performances of different sampling strategies in order to reduce the number of examples needed. Two windows based active learning algorithms from state-of-art are compared to a classical stratified random sampling and a third combining active learning and stratified strategies is proposed. The efficiency of these strategies is evaluated on two medium size French cities, Strasbourg and Rennes, associated to different datasets. Results demonstrate that classical stratified random sampling can in some cases be just as effective as active learning methods and that it should be used more frequently to evaluate new active learning methods. Moreover, the active learning strategies proposed in this work enables to reduce the computational runtime by selecting multiple windows at each iteration without increasing the number of windows needed.

2017-04-01

Conflict over natural resources figured prominently in the urban areas. On the one hand there is a constant need for space for the construction of new buildings for housing, agriculture and industrial production, and on the other hand the resources need protection because of the threat of degradation or even complete destruction. Considering the fact that urbanization is one of the most serious threats to geodiversity, it is important that this issue is taken into account in spatial development plans and georesource management strategies in urban areas. The geodiversity, as well as natural resource, must be managed in a sustainable manner in which it is very important its protection. The mapping of specific categories of geodiversity (geological, geomorphological, hydrological and soil) on the basis of quantitative assessment with the use of Geographic Information Systems (GIS) can allow spatial planners and managers to take further steps that would reduce threats and protect the natural values. This work presents the application of geodiversity evaluation method by using the geodiversity index (Gd), based on the quantity of abiotic elements and relief roughness within a spatial unit in the case of the City of Belgrade, Serbia. The acquired results are analyzed in the context of sustainable use of georesources and the threats to which geodiversity is exposed due to the development of the city.

A Socio-Hydrological Model of the Voluntary Urban Water Conservation Behavior during Droughts

NASA Astrophysics Data System (ADS)

Sangwan, N.; Eisma, J. A.; Sung, K.; Yu, D. J.

2016-12-01

Several cities across the globe are increasingly struggling to meet the water demands of their population. By 2050, nearly 160 million urban dwellers are likely to face perennial water shortage due to ever rising population numbers and climate change. As observed once again during recent drought in California, voluntary water conservation is a key approach for managing urban water availability during periods of constrained supply. It relies on behavioral adaptation that is critical for long-term reductions in water use and building drought resilient communities. Strong interdependencies between human group behavior and regional hydrology in this context entail that the two components be coupled together in a socio-hydrology model to fully understand the dynamics of urban water systems. This work proposes a conceptual framework for one such model and simulates the dynamics of a voluntary conservation program in Marin Municipal Water District, California using dynamic systems modeling approach. Through this model, we plan to assess the effects of different social factors (such as social concern and conformist tendencies) and climato-hydrological conditions (viz. storage levels and weather forecast) on the trajectory of a voluntary conservation program. Our preliminary results have indicated several `tipping points' which can be capitalized on by policy makers to boost conservation at low social costs.

Urban regulatory focus: a new concept linking city size to human behaviour

PubMed Central

2018-01-01

Why do people in big cities behave differently to those living in small cities? To answer this question, in this paper a new concept of urban dynamics is presented that links city size to human behaviour. The concept has its origins in regulatory focus theory. According to the theory, goal-directed behaviour is regulated by two motivational systems, promotion and prevention. Individuals motivated by promotion goals (growth, accomplishment) focus on winning and tend to take risks, whereas those driven by prevention goals (safety, security) focus on not losing and try to avoid risk. Here we elaborate on the existing literature by linking the theory to the urban context. In our conceptualization, cities are powerful regulatory systems, and as such they impinge upon the way people regulate themselves in the urban space. Evidence from signal detection analysis is provided that supports this concept. The experience of a big-city context intensified both promotion-focused behaviour (a risky bias) for promotion-focused participants and prevention-focused behaviour (a conservative bias) for prevention-focused participants. The experience of a small-city context encouraged the opposite behavioural pattern in both cases. These findings suggest that the urban environment can influence the regulatory focus strategies of an individual in a way that cannot simply be explained by their personal regulatory focus. Specifically, the likelihood of one's behaving in a promotion- or prevention-oriented manner is dependent both on one's chronic regulatory focus and also on the urban context in which one lives. Based on this, we maintain that vibrant cities with a large population and a fast pace of life encourage extreme and polarized behaviours, whereas cities with a smaller population and a slower pace of life encourage more moderate and less polarized behavioural responses, which may explain why people in big cities take more risks, do more business, produce and spend more, and even walk faster.

While cities cover only 2% of the Earth's surface, over 50% of the world's people live in urban environments. Precisely because of their population density, cities can play a large role in reducing or exacerbating the global impact of climate change. The actions of cities could hold the key to slowing down climate change. Urban dwellers are becoming more aware of the need to reduce their carbon usage and to implement adaptation strategies. However, messaging around these strategies has not been comprehensive and adaptation to climate change requires local knowledge, capacity and a high level of coordination. Unless urban populations understand climate change and its impacts it is unlikely that cities will be able to successfully implement policies that reduce anthropogenic climate change. Informal and formal educational institutions in urban environments can serve as catalysts when partnering with climate scientists, educational research groups, and public policy makers to disseminate information about climate change and its impacts on urban audiences. The Climate and Urban Systems Partnership (CUSP) is an interdisciplinary network designed to assess and meet the needs and challenges of educating urban audiences about climate change. CUSP brings together organizations in Philadelphia, Pittsburgh, Queens, NY and Washington, DC to forge links with informal and formal education partners, city government, and policy makers. Together this network will create and disseminate learner-focused climate education programs and resources for urban audiences that, while distinct, are thematically and temporally coordinated, resulting in the communication of clear and consistent information and learning experiences about climate science to a wide public audience. Working at a community level CUSP will bring coordinated programming directly into neighborhoods presenting the issues of global climate change in a highly local context. The project is currently exploring a number of models for community programming and this session will present early results of these efforts while engaging participants in exploring approaches to connecting urban communities and their local concerns to the issues of global climate change.

Sustainable development or sustainability has been highlighted as an essential principle in urban master planning, with increasing recognition that uncontrollable urbanization may well give rise to various issues such as overexploitation of natural resources, ecosystem destruction, environmental pollution and large-scale climate change. Thus, it is deemed necessary to modify the existing urban and regional administrative system so as to cope with the challenges urban planning is being confronted with and realize the purpose of urban sustainability. This paper contributed to proposing a mechanism which helps to make urban planning with full consideration of issues with respect to sustainable development. Wemore » suggested that the integration of urban planning, SEA and ecological planning be a multi-win strategy to offset deficiency of each mentioned political tool being individually applied. We also proposed a framework where SEA and ecological planning are fully incorporated into urban planning, which forms a two-way constraint mechanism to ascertain environmental quality of urban planning, although in practice, planning and SEA processes may conditionally be unified. Moreover, as shown in the case study, the integration of the three political tools may be constrained due to slow changes in the contextual factors, in particular the political and cultural dimensions. Currently within the context of China, there may be three major elements which facilitate integration of the three political tools, which are (1) regulatory requirement of PEIA on urban planning, (2) the promotion or strong administrative support from government on eco-district building, and (3) the willingness of urban planners to collaborate with SEA experts or ecologists.« less

The evolution of the urban system in Romania in the last decades has been strongly influenced by its historical background, as well as the changing political, social and economic context. The main step in this process was marked by the year 2004 when 38 settlements received the urban status, influencing thus not only the country's urbanization level but the increased inter-regional disparities as well. The paper aims to analyze the post-urbanization process in Romania, highlighting those factors which have contributed to the deepening development differences between the country's urban areas.

Background Social capital is essential for the successful development of young people. The current study examines direct measures of social capital in young people in five urban global contexts. Methods The Well Being of Adolescents in Vulnerable Environments (WAVE) is a global study of young people aged 15 to 19 years living in disadvantaged, urban settings. Respondent Driven Sampling (RDS) was used to recruit approximately 500 participants from each site. The sample included 2339 young people (mean age 16.7 years; 47.5% female). We examined the associations between social capital in four domains -family, school, peers and neighborhood -and demographic characteristics using gender stratified Ordinary Least Squares regression. We also examined associations between self-reported health and the four social capital domains is minimal. School enrollment was positively associated with social capital for young women in Baltimore, Delhi, and Shanghai: the association was less consistent for young men. The same pattern is true for perceived wealth. Unstable housing was associated with low familial social capital in all groups except young women in Shanghai and young men in Ibadan and Johannesburg. Being raised outside a two-parent family has a widespread, negative association with social capital. Self-reported health had a mainly positive association with social capital with the most consistent association being neighborhood social capital, Conclusions Different types of social capital interact with social contexts and gender differently. Strategies that aim to build social capital as part of risk reduction and positive youth development programming need to recognize that social capital enhancement may work differently for different groups and in different settings.

The objective of this session is to foster a dialogue between experts working on global-scale, climate change and cities assessments in order to simultaneously present state-of-the-art knowledge on how cities are responding to climate change and to define emerging opportunities and challenges to the effective placement of this knowledge in the hands of local stakeholders and decision-makers. We will present the UCCRN and the Second UCCRN Assessment Report on Climate Change and Cities (ARC3-2), the second in an ongoing series of global, interdisciplinary, cross-regional, science-based assessments to address climate risks, adaptation, mitigation, and policy mechanisms relevant to cities. This is an especially important time to examine these issues. Cities continue to act as world leaders in climate action. Several major climate change assessment efforts are in full swing, at a crucial stage where significant opportunities for the co-production of knowledge between researchers and stakeholders exist. The IPCC AR5 Working Group II and III Reports have placed unprecedented attention on cities and urbanization and their connection to the issue of climate change. Concurrently several major, explicitly city-focused efforts have emerged from the Urban Climate Change Research Network (UCCRN), ICLEI, the Durban Adaptation Charter (DAC), C40, Future Earth, and the Urbanization and Global Environmental Change (UGEC) Project, among others. The underlying rationale for the discussion will be to identify methods and approaches to further foster the development and dissemination of new climate change knowledge and information that will be useful for cities, especially in small and medium-sized cities and in the developing country context where the demand is particularly acute. Participants will leave this session with: · The latest scientific data and state-of-the-knowledge on how cities are responding to climate change · Emerging opportunities and challenges to the effective placement of this knowledge in the hands of local stakeholders and decision-makers and for urban resilience and adaptation action · How practitioner-scientist interactions can work best · Synergies between the IPCC, ARC3, and other climate and cities assessments

Research within the disciplines of Social Work and Education has for sometime acknowledged the tragedy, trauma, conflict and misery that can be experienced by workers in their associated professions. More recently, there has been an aligned interest in the role of passion, emotion and energy in sustaining these professionals through such experiences. This paper contributes to the growing literature in this area by reporting on a study conducted with five social workers and six teachers who work in Australian lower socioeconomic, urban-fringe and communities. It also engages the concept of the 'personal domain' to explore how these social workers and teachers cannot only survive, but can actually thrive in demanding work contexts. The methodology adopted for the study was an appreciative enquiry approach, where these professionals, each with over a decade of experience in urban-fringe communities, were recruited via non-probability, purposive, snowballing techniques and interviewed about what sustained them in their work during November 2008-February 2009. Thematic analysis of the interviews found that participants not only identified specific survival strategies, but could also articulate how their life experiences, ideologies, beliefs, values and other life resources informed their work in ways that aided their flourishing as professionals. The paper concludes by calling for further research into the work of social work and teaching professionals from a 'personal domain' perspective and considering the potential implications of such research for these professions, particularly in terms of promoting professional trajectories characterised first by endurance, and then by development and triumph. © 2011 Blackwell Publishing Ltd.

2017-02-28

With new approaches in imaging-from new tools or reagents to processing algorithms-come unique opportunities and challenges to our understanding of biological processes, structures, and dynamics. Although innovations in super-resolution imaging are affording novel perspectives into how molecules structurally associate and localize in response to, or in order to initiate, specific signaling events in the cell, questions arise as to how to interpret these observations in the context of biological function. Just as each neighborhood in a city has its own unique vibe, culture, and indeed density, recent work has shown that membrane receptor behavior and action is governed by their localization and association state. There is tremendous potential in developing strategies for tracking how the populations of these molecular neighborhoods change dynamically.

The Innovation Deficit in Urban Water: The Need for an Integrated Perspective on Institutions, Organizations, and Technology

Abstract Interaction between institutional change and technological change poses important constraints on transitions of urban water systems to a state that can meet future needs. Research on urban water and other technology-dependent systems provides insights that are valuable to technology researchers interested in assuring that their efforts will have an impact. In the context of research on institutional change, innovation is the development, application, diffusion, and utilization of new knowledge and technology. This definition is intentionally inclusive: technological innovation will play a key role in reinvention of urban water systems, but is only part of what is necessary. Innovation usually depends on context, such that major changes to infrastructure include not only the technological inventions that drive greater efficiencies and physical transformations of water treatment and delivery systems, but also the political, cultural, social, and economic factors that hinder and enable such changes. On the basis of past and present changes in urban water systems, institutional innovation will be of similar importance to technological innovation in urban water reinvention. To solve current urban water infrastructure challenges, technology-focused researchers need to recognize the intertwined nature of technologies and institutions and the social systems that control change.

To achieve a successful and sustainable adaptation to climate change we need to transform the way we think about change. Much water management research has focused on technical innovation with a range of new solutions developed to achieve a 'more sustainable and integrated urban water management cycle'. But Danish municipalities and utility companies are struggling to bring such solutions into practice. 'Green infrastructure', for example, requires the consideration of a larger range of aspects related to the urban context than the traditional urban water system optimization. There is the need for standardized methods and guidelines to organize transdisciplinary processes where different types of knowledge and perspectives are taken into account. On the basis of the macro-meso-micro pattern inspired by complexity science and transition theory, we developed a conceptual framework to organize processes addressing the complexity characterizing urban water management in the context of climate change. In this paper the framework is used to organize a research process aiming at understanding and unfolding urban dynamics for sustainable transition. The final goal is to enable local authorities and utilities to create the basis for managing and catalysing the technical and organizational innovation necessary for a sustainable transition towards climate change adaptation in urban areas.

Objectives Given the need for knowledge on the restorative potential of urban settings, we sought to estimate the effects of personal and contextual factors on preferences and restoration likelihood assessments for different urban activities-in-environments. We also sought to study the generality of these effects across different countries. Methods We conducted a true experiment with convenience samples of university students in the Netherlands (n = 80), Sweden (n = 100), and the USA (n = 316). In each country, the experiment had a mixed design with activities-in-environments (sitting in a park, sitting in a cafe, walking in a shopping mall, walking along a busy street) manipulated within-subjects and the need for restoration (attentional fatigue, no attentional fatigue) and immediate social context (in company, alone) manipulated between-subjects. The manipulations relied on previously tested scenarios describing everyday situations that participants were instructed to remember and imagine themselves being in. For each imagined situation (activity-in-environment with antecedent fatigue condition and immediate social context), subjects provided two criterion measures: general preference and the likelihood of achieving psychological restoration. Results The settings received different preference and restoration likelihood ratings as expected, affirming that a busy street, often used in comparisons with natural settings, is not representative of the restorative potential of urban settings. Being with a close friend and attentional fatigue both moderated ratings for specific settings. Findings of additional moderation by country of residence caution against broad generalizations regarding preferences for and the expected restorative effects of different urban settings. Conclusions Preferences and restoration likelihood ratings for urban activity-environment combinations are subject to multiple personal and contextual determinants, including level of attentional fatigue, being alone versus in company, and broader aspects of the urban context that vary across cities and countries. Claims regarding a lack of restorative quality in urban environments are problematic. PMID:26731272

Recent social changes and rising social inequality in the rural United States have affected the experience and meaning of mental illness and treatment seeking within rural communities. Rural Americans face serious mental health disparities, including higher rates of suicide and depression compared with residents of urban areas, and substance abuse rates in rural areas now equal those in urban areas. Despite these increased risks, people living in rural areas are less likely than their urban counterparts to seek or receive mental health services. This Open Forum calls for a research agenda supported by anthropological theory and methods to investigate the significance of this changed rural social context for mental health.

The Usability of Online Geographic Virtual Reality for Urban Planning

NASA Astrophysics Data System (ADS)

Zhang, S.; Moore, A. B.

2013-08-01

Virtual reality (VR) technology is starting to become widely and freely available (for example the online OpenSimulator tool), with potential for use in 3D urban planning and design tasks but still needing rigorous assessment to establish this. A previous study consulted with a small group of urban professionals, who concluded in a satisfaction usability test that online VR had potential value as a usable 3D communication and remote marketing tool but acknowledged that visual quality and geographic accuracy were obstacles to overcome. This research takes the investigation a significant step further to also examine the usability aspects of efficiency (how quickly tasks are completed) and effectiveness (how successfully tasks are completed), relating to OpenSimulator in an urban planning situation. The comparative study pits a three-dimensional VR model (with increased graphic fidelity and geographic content to address the feedback of the previous study) of a subdivision design (in a Dunedin suburb) against 3D models built with GIS (ArcGIS) and CAD (BricsCAD) tools, two types of software environment well established in urban professional practice. Urban professionals participated in the study by attempting to perform timed tasks correctly in each of the environments before being asked questions about the technologies involved and their perceived importance to their professional work. The results reinforce the positive feedback for VR of the previous study, with the graphical and geographic data issues being somewhat addressed (though participants stressed the need for accurate and precise object and terrain modification capabilities in VR). Ease-ofuse and associated fastest task completion speed were significant positive outcomes to emerge from the comparison with GIS and CAD, pointing to a strong future for VR in an urban planning context.

Sustainability on the urban scale: Proposal of a structure of indicators for the Spanish context

DOE Office of Scientific and Technical Information (OSTI.GOV)

Braulio-Gonzalo, Marta, E-mail: braulio@uji.es; Bovea, María Dolores, E-mail: bovea@uji.es; Ruá, María José, E-mail: rua@uji.es

Some efforts to assess sustainability on the urban scale have been made and different tools for measuring the impact on and caused by cities have emerged. However, the sustainability concept varies from region to region, and indicators to measure it should be suitable for the context-specific conditions of the region under study. After doing a comprehensive review of the indicators included in 13 tools developed to assess urban sustainability of cities, this article proposes a new structure of indicators adapted to a Mediterranean city in Spain. The proposed structure is based on a two-level scheme that consists in 14 categoriesmore » and 63 subcategories, which agglutinate urban sustainability indicators according to their purpose. This structure suggests a set of comprehensible qualitative and quantitative indicators that are easily applicable on neighbourhood or city scales. Given the similar features of Mediterranean countries in terms of environmental and socio-economic aspects, the proposed structure could be extrapolated to other countries with climatic and cultural similarities. Otherwise, the system is a useful tool in the decision-making process to help the different stakeholders involved in new urban developments and regeneration projects in existing neighbourhoods, such as developers, urban planners and public administrations. - Highlights: • Comprehensive review of 13 urban sustainability assessment tools • Proposal of a two-level structure to cluster urban sustainability indicators • Inclusion of sustainability criteria for urban planning projects and interventions.« less

Urbanization, Agricultural Intensification, and Habitat Alteration in Vietnam: Modeling Transitional Development and Emerging Infectious Diseases

NASA Astrophysics Data System (ADS)

Fox, J.; Saksena, S.; Spencer, J.; Finucane, M.; Sultana, N.

2012-12-01

Our overarching hypothesis is that new risks, in this case the H5N1 strain of avian influenza, emerge during transitions between stages of development. Moreover, these risks are not coincidental but occur precisely because of the in-between nature of the coupled human-natural system at the point when things are neither traditional nor modern but resemble the state of chaos, release and reorganization. We are testing this hypothesis in Vietnam using demographic, social, economic, and environmental data collected in national censuses and analyzed at commune and district levels to identify communes and districts that are traditional, modern, and transitional (peri-urban). Using data from the 2006 agricultural census that capture both the changing nature of the built environment (types of sanitation systems) and the loss of and diversification of agriculture systems (percent of households whose major source of income is from agriculture, and percent of land under agriculture, forests, and aquaculture), and a normalized difference vegetation index from 2006 Landsat images we created a national scale urbanicity map for Vietnam. Field work in the summer of 2011 showed this map to be an accurate (approximately 85%) approximation of traditional (rural), transitional (periurban), and modern (urban) communes. Preliminary results suggest that over 7% of the country's land area and roughly 15% of its population resides in periurban neighborhoods, and that these areas do have a statistically significant greater incidence of AVI as measured in chicken deaths than traditional and modern communes (Table 1). Transitional neighborhoods such as these force planners to ask two questions. To what extent does the dichotomy of urban/rural makes sense in the context of Vietnam, when large areas and parts of the population are caught between the two? Second, how can planners and policy makers effectively provide for basic public goods and services in these contexts?Classification of places in Vietnam based on agricultural income, toilets and land under agriculture, forests and aqua (homes and enterprises) and NDVIσ In general denser vegetation canopies have higher NDVI valueφ Simpson's index, a value of 0 indicates no diversity and a value of 1 indicated infinite diversity

2015-01-01

Background Many low- and middle-income countries are undergoing a nutrition transition associated with rapid social and economic transitions. We explore the coexistence of over and under- nutrition at the neighborhood and household level, in an urban poor setting in Nairobi, Kenya. Methods Data were collected in 2010 on a cohort of children aged under five years born between 2006 and 2010. Anthropometric measurements of the children and their mothers were taken. Additionally, dietary intake, physical activity, and anthropometric measurements were collected from a stratified random sample of adults aged 18 years and older through a separate cross-sectional study conducted between 2008 and 2009 in the same setting. Proportions of stunting, underweight, wasting and overweight/obesity were dettermined in children, while proportions of underweight and overweight/obesity were determined in adults. Results Of the 3335 children included in the analyses with a total of 6750 visits, 46% (51% boys, 40% girls) were stunted, 11% (13% boys, 9% girls) were underweight, 2.5% (3% boys, 2% girls) were wasted, while 9% of boys and girls were overweight/obese respectively. Among their mothers, 7.5% were underweight while 32% were overweight/obese. A large proportion (43% and 37%%) of overweight and obese mothers respectively had stunted children. Among the 5190 adults included in the analyses, 9% (6% female, 11% male) were underweight, and 22% (35% female, 13% male) were overweight/obese. Conclusion The findings confirm an existing double burden of malnutrition in this setting, characterized by a high prevalence of undernutrition particularly stunting early in life, with high levels of overweight/obesity in adulthood, particularly among women. In the context of a rapid increase in urban population, particularly in urban poor settings, this calls for urgent action. Multisectoral action may work best given the complex nature of prevailing circumstances in urban poor settings. Further research is needed to understand the pathways to this coexistence, and to test feasibility and effectiveness of context-specific interventions to curb associated health risks. PMID:26098561

Impact of Thermal Inertia on Urban Climatology: A Case Study of Delhi

NASA Astrophysics Data System (ADS)

Berwal, S.; Kumar, D.; Singh, V. P.; Pandey, A. K.; Kumar, K.

2016-12-01

The ability with which a material can absorb, restore the heat and release it later during the nighttime is known as thermal inertia. In the context to urban areas, it measures the sub-surface's ability to store heat during the day and release it during the night. It prevents the overheating in summer and maintains heat during the winter thereby safeguarding the building comfort level. Due to huge population and urban sprawl this study can be very useful for Delhi and cities like it. The climatic modification in the context of urban areas due to human activities in relation to rural areas is termed as the urban heat island effect (UHI). The modelling for formation of urban UHI has been done using the geospatial technique. Apart from temperature, the amount of dust in the atmosphere is also a significant contributor in modifying the UHI formation. It is also an attempt to establish the role of land use and land cover patterns and respective thermal inertia affecting this phenomenon. The thermal inertia over Delhi-NCR was estimated using surface albedo and daytime-nighttime temperature differences from MODIS datasets. Higher thermal inertia were observed in urban areas than that of rural areas during the analysis of the thermal inertia maps. Furthermore, the study also reveals that the urban heat island intensity (UHI) and the thermal inertia has a relationship of strong inverse correlation. The results of this study will provide useful insights for urban planners and the local governments to devise appropriate strategies for making the urban climate favourable for the city residents.

2015-01-22

Seasonal influenza vaccine uptake among school-age children has been low, particularly among rural children, even in jurisdictions in Canada where this immunization is publicly funded. Providing this vaccination at school may be convenient for parents and might contribute to increased vaccine uptake, particularly among rural children. We explore the construct of convenience as an advantage of school based influenza vaccination. We also explore for rural urban differences in this construct. Participants were parents of school-aged children from Alberta, Canada. We qualitatively analyzed focus group data from rural parents using a thematic template that emerged from prior work with urban parents. Both groups of parents had participated in focus groups to explore their perspectives on the acceptability of adding an annual influenza immunization to the immunization program that is currently delivered in Alberta schools. Data from within the theme of 'convenience' from both rural and urban parents were then further explored for sub-themes within convenience. Data were obtained from nine rural and nine urban focus groups. The template of themes that had arisen from prior analysis of the urban data applied to the rural data. Convenience was a third level theme under Advantages. Five fourth level themes emerged from within convenience. Four of the five sub-themes were common to both rural and urban participants: reduction of parental burden to schedule, reduction in parental lost time, decrease in parental stress and increase in physical access points for influenza immunization. The fifth subtheme, increases temporal access to influenza immunization, emerged uniquely from the rural data. Both rural and urban parents perceived that convenience would be an advantage of adding an annual influenza immunization to the vaccinations currently given to Alberta children at school. Improving temporal access to such immunization may be a more relevant aspect of convenience to rural than to urban parents.

Built Environment and Active Commuting: Rural-Urban Differences in the U.S.

The purpose of this research was to investigate rural-urban differences in participation rates in three modes of active commuting (AC) and their built environmental correlates. The 2010 Census supplemented with other datasets were used to analyze AC rates in percent of workers age 16+ walking, biking, or taking public transportation to work in 70,172 Census tracts, including 12,844 rural and 57,328 urban. Random-intercept factional logit regressions were used to account for zero-inflated data and for clustering of tracts within counties. We found that the average AC rates were 3.44% rural and 2.77% urban (p<0.01) for walking to work, 0.40% rural and 0.58% urban (p<0.01) for biking to work, and 0.59% rural and 5.86% urban (p<0.01) for public transportation to work. Some environmental variables had similar relationships with AC in rural and urban tracts, such as a negative association between tract greenness and prevalence of walking to work. Others had opposite correlational directions for rural vs. urban, such as street connectivity for walking to work and population density for both walking to work and public transportation to work. We concluded that rurality is an important moderator in AC-environment relationships. In developing strategies to promote AC, attention needs to be paid to rural-urban differences to avoid unintended consequences.

Encounters and Content Sharing in an Urban Village: Reading Texts Through an Archaeological Lens

NASA Astrophysics Data System (ADS)

Garcia, Nicole; Foth, Marcus; Hearn, Greg

Archaeology provides a framework of analysis and interpretation that is useful for disentangling the textual layers of a contemporary lived-in urban space. The producers and readers of texts may include those who planned and developed the site and those who now live, visit, and work there. Some of the social encounters and content sharing between these people may be artificially produced or manufactured in the hope that certain social situations will occur. Others may be serendipitous. With archaeology's original focus on places that are no longer inhabited, it is often only the remaining artifacts and features of the built environment that form the basis for interpreting the social relationships of past people. Our analysis, however, is framed within a contemporary notion of archaeological artifacts in an urban setting. Unlike an excavation, where the past is revealed through digging into the landscape, the application of landscape archaeology within a present day urban context is necessarily more experiential, visual, and based on recording and analyzing the physical traces of social encounters and relationships between residents and visitors. These physical traces are present within the creative content, and the built and natural elements of the environment. This chapter explores notions of social encounters and content sharing in an urban village by analyzing three different types of texts: the design of the built environment; content produced by residents through a geospatial web application; and, print and online media produced in digital storytelling workshops.

Urban geomorphological heritage - A new field of research

NASA Astrophysics Data System (ADS)

Reynard, Emmanuel; Pica, Alessia; Coratza, Paola

2017-04-01

Urbanization is one of the major challenges that the world faces. In 2015, 54% of the world population was living in urban areas and in some countries this percentage is close to 100% (Singapore 100%; Qatar 99%; Belgium 98%). In several parts of the world annual urbanization rates exceed 5% (e.g. Oman 8.54%; Rwanda 6.43%; Burkina Faso 5.87%), which means that urban sprawl is a widespread phenomenon. Urbanization and correlated infrastructure building highly impact and sometimes completely destroy natural landforms. Geomorphological heritage research has traditionally focused on rural or natural regions, in particular protected areas (nature parks, geoparks). We consider that urban areas, which have been poorly investigated until now, are particularly interesting in a geomorphological heritage point of view for almost three reasons: (i) The geomorphological context (site) of some cities is part of their "image" and their fame (e.g. the sugarloaf of Rio de Janeiro); (ii) Urban sprawl often interacts with landforms, which addresses the challenge of geoheritage protection in fast urbanizing areas; (iii) Cities are often tourist destinations, which creates a potential for a geotourist promotion of their geomorphological heritage. This study addresses the main challenges research on geomorphological heritage is facing in urban contexts: (i) the complex interrelationships between natural landforms and urban forms; (ii) the partial or total invisibility of landforms and sediments that are covered or destroyed by urban infrastructures; (iii) man-made landforms as part of urban geomorphological heritage; (iv) the suitability of some landforms (valleys, gullies, mounts) for specific urban uses; (v) the geomorphic constraints of landforms on urban development; and (vi) the importance of some landforms for the urban landscape and the image of the cities. To address these challenges a methodological framework is proposed, which combines: (i) the geomorphological analysis of the urban landscape through geomorphological mapping (with use of a specific legend for man-made landforms) and geohistorical analysis of landscape evolution (historical maps processing); (ii) the selection, characterization and assessment of urban geomorphosites; (iii) proposals for the conservation and promotion (geotourism) of the urban geomorphological heritage.

Next generation wireless communication systems will consist of a large number of mobile or static terminals and should be able to fulfill multiple requirements depending on the current situation. Low latency and high packet success transmission rates should be mentioned in this context and can be summarized as ultra-reliable communications (URC). Especially for domains like mobile gaming, mobile video services but also for security relevant scenarios like traffic safety, traffic control systems and emergency management URC will be more and more required to guarantee a working communication between the terminals all the time.

Preliminary Analysis of the efficacy of Artificial neural Network (ANN) and Cellular Automaton (CA) based Land Use Models in Urban Land-Use Planning

NASA Astrophysics Data System (ADS)

Harun, R.

2013-05-01

This research provides an opportunity of collaboration between urban planners and modellers by providing a clear theoretical foundations on the two most widely used urban land use models, and assessing the effectiveness of applying the models in urban planning context. Understanding urban land cover change is an essential element for sustainable urban development as it affects ecological functioning in urban ecosystem. Rapid urbanization due to growing inclination of people to settle in urban areas has increased the complexities in predicting that at what shape and size cities will grow. The dynamic changes in the spatial pattern of urban landscapes has exposed the policy makers and environmental scientists to great challenge. But geographic science has grown in symmetry to the advancements in computer science. Models and tools are developed to support urban planning by analyzing the causes and consequences of land use changes and project the future. Of all the different types of land use models available in recent days, it has been found by researchers that the most frequently used models are Cellular Automaton (CA) and Artificial Neural Networks (ANN) models. But studies have demonstrated that the existing land use models have not been able to meet the needs of planners and policy makers. There are two primary causes identified behind this prologue. First, there is inadequate understanding of the fundamental theories and application of the models in urban planning context i.e., there is a gap in communication between modellers and urban planners. Second, the existing models exclude many key drivers in the process of simplification of the complex urban system that guide urban spatial pattern. Thus the models end up being effective in assessing the impacts of certain land use policies, but cannot contribute in new policy formulation. This paper is an attempt to increase the knowledge base of planners on the most frequently used land use model and also assess the relative effectiveness of the two models, ANN and CA, in urban planning. The questions that are addressed in this research are: a) What makes ANN models different from CA models?; b) Which model has higher accuracy in predicting future urban land use change?; and c) Are the models effective enough in guiding urban land use policies and strategies? The models that are used for this research are Multilayer Perceptron (MLP) and CA model, available in IDRISI Taiga. Since, the objective is to perform a comparative analysis and draw general inferences irrespective of specific urban policies, the availability of data was given more emphasis over the selection of particular location. Urban area in Massachusetts was chosen to conduct the study due to data availability. Extensive literature review was performed to understand the functionality of the two models. The models were applied to predict future changes and the accuracy assessment was performed using standard matrix. Inferences were drawn about the applicability of the models in urban planning context along with recommendations. This research will not only develop understanding of land use models among urban planners, but also will create an environment of coupled research between planners and modellers.

Neighborhood Contexts and Marijuana Use Among Urban Dwelling Emerging Adult Men.

PubMed

Taggart, Tamara; Brown, Andre L; Kershaw, Trace

2018-01-01

Neighborhoods are key socio-environmental contexts for marijuana use during emerging adulthood. This study examined the relationships between neighborhood context, traditional masculine norms (status, toughness, and anti-femininity), and marijuana use among 119 majority African American emerging adult men in a small urban community. Poisson regression models were used to determine the associations between neighborhood problems, social cohesion, and marijuana use. Moderator effects were examined to determine if masculinities modified these associations. Neighborhood problems and social cohesion were positively associated with marijuana use. Men who had a lower endorsement of some traditional masculine norms had greater marijuana use compared to men with a higher endorsement of these norms. These findings have implications for intervention strategies and policies.

Tension Among Women in North India: An Idiom of Distress and a Cultural Syndrome.

PubMed

Weaver, Lesley Jo

2017-03-01

The existing literature on Indian ethnopsychology has long asserted that somatization is a key aspect of experiences of distress. The study of idioms of distress arose out of work done in India (Nichter in Cult Med Psychiatry 5(4):379-408, 1981), but ironically, little subsequent work has systematically explored idioms of distress in this part of the world. This ethnographic study focused on the term tension (tenśan) and its relation to a cultural syndrome among women in urban North India. This syndrome appears to involve rapid-onset anger, irritation, rumination, and sleeplessness as key symptoms. It is often linked to specific circumstances such as domestic conflict and is associated with the stresses of modern urban life. People who report more symptoms of tension had consistently higher scores on the Hopkins Symptoms Checklist-25 for depression and anxiety. In this cultural context where psychiatric care is highly stigmatized, the language of tension can aid providers of mental healthcare (many of whom, in India, are not psychiatrists or psychologists) to identify and communicate effectively with potential patients whose mental healthcare needs might otherwise go unaddressed.

2017-07-01

Sarbagita (Denpasar, Badung, Gianyar, and Tabanan) Metropolitan Area is one of seven metropolitan areas in Indonesia, located in the coastal region of Bali Island. Providing clean water in the coastal region is generally constrained by the limited sources of water. Besides, there is also disparity issue between the core and peri-urban area. The purpose of this study is to explore the conditions of water supply provision in Metropolitan Sarbagita in the context of coastal and peri-urban region. The methods of analysis used are descriptive and association analysis. The analysis shows that the location in the coastal area and peri-urban area does not affect the water supply provision for the case of daily safe water yet it does affect significantly in the specific context of drinking water source.

Urban food insecurity in the context of high food prices: a community based cross sectional study in Addis Ababa, Ethiopia

PubMed Central

2014-01-01

Background High food prices have emerged as a major global challenge, especially for poor and urban households in low-income countries such as Ethiopia. However, there is little empirical evidence on urban food security and how people living in urban areas are coping with sustained high food prices. This study aims to address this gap by investigating the food insecurity situation in urban Ethiopia -a country experiencing sustained high food prices, high rates of urban poverty, and a growing urban population. Methods A community based cross-sectional study was conducted from January 18 to February 14, 2012. A total of 550 households were selected from three sub-cities of Addis Ababa using three-stage sampling technique. Data were collected using questionnaire based interview with household heads. Items in the questionnaire include, among others, basic socioeconomic variables, dietary diversity and coping strategies. Food security status of households was assessed by a Household Food Insecurity Access Score. Data analysis was done using SPSS software and both univariate and bivariate analysis were done. Results The study found that 75% of households were food insecure and 23% were in a state of hunger. Households with higher food insecurity scores tend to have lower dietary diversity and are less likely to consume high quality diets. Reduction in meal size and shifting to poor quality/less expensive/food types were among the common coping strategies to high food price used by households. Household incomes, occupational and educational status of household heads were significant determinants of food security. Conclusion Food insecurity in Ethiopia is not only a rural problem. Urban food insecurity is a growing concern due to the toxic combination of high rates of urban poverty, high dependency of urban households on food supplied by the market, and fluctuating food prices. Household food insecurity was particularly high among low income households and those headed by uneducated, daily wagers and government employed household heads. Therefore, policy makers should work on stabilization of the food market and creating opportunities that could improve the livelihood and purchasing power of urban households. PMID:24993286

Meeting the needs of urban high-risk/low-resource communities is one of the most critical challenges in improving climate resilience nationally, but little tailored information exists to guide community engagement efforts specifically for these contexts. This case study describes a collaboration between universities, local governments, and community members working in underserved neighborhoods of the City of Baltimore and Prince George's County, Maryland. In service of current and developing community programs, the team surveyed residents door-to-door about their perceptions of the socio-environmental risks they face, their priorities for change, and the ways in which communication may build protective social capital. We highlight theoretical, applied, and pedagogical aspects of the study that inform both the promise and limitations of these collaborations. These include: 1) the role of citizen participation in climate adaptation decision-making; 2) the meaning, use, and potential impact of community data; 3) balancing differing organizational priorities, timelines, and cultures within community-based projects; and 4) research participation of undergraduate students. The results of the survey illuminate climate risk perceptions in neighborhoods facing complex stressors with lessons for communication and engagement in other urban areas facing similar adaptation challenges.

Understanding the flows of people moving through the built environment is a vital source of information for the planners and policy makers who shape our cities. Smart phone applications enable people to trace themselves through the city and these data can potentially be then aggregated and visualised to show hot spots and trajectories of macro urban movement. In this paper our aim is to develop procedures for cleaning, aggregating and visualising human movement data and translating this into policy relevant information. In conducting this research we explore using bicycle data collected from a smart phone application known as RiderLog. We focus on the RiderLog application initially in the context of Sydney, Australia and discuss the procedures and challenges in processing and cleaning this data before any analysis can be made. We then present some preliminary map results using the CartoDB online mapping platform where data are aggregated and visualised to show hot spots and trajectories of macro urban movement. We conclude the paper by highlighting some of the key challenges in working with such data and outline some next steps in processing the data and conducting higher volume and more extensive analysis.

The Cape Town Case Study (CTCS) was a multi-institutional collaborative project initiated by CUBES, a knowledge networking initiative of UNESCO's Ecological Sciences Division and the Earth Institute at Columbia University. Cape Town was selected as a CUBES site on the basis of its high biological and cultural significance, together with its demonstrated leadership in promoting urban sustainability. The CTCS was conducted by the Cape Town Urban Biosphere Group, a cross-disciplinary group of specialists drawn from national, provincial, municipal, and civil society institutions, mandated to examine the potential value of the UNESCO Biosphere Reserve concept as a tool for environmental management, social inclusion, and poverty alleviation in Cape Town. This article provides a contextualization of the CTCS and its collaborative process. It also reviews the biosphere reserve concept relative to urban sustainability objectives and proposes a more functional application of that concept in an urban context. A detailed analysis of key initiatives at the interface of conservation and poverty alleviation is provided in table format. Drawing on an examination of successful sustainability initiatives in Cape Town, specific recommendations are made for future application of the biosphere reserve concept in an urban context, as well as a model by which urban areas might affiliate with the UNESCO World Network of Biosphere Reserves, and criteria for such affiliation.

The prevalence of osteoporosis in Sub-Saharan African (SSA) countries is low, however, as urbanization takes root, it is predicted that bone health will decrease dramatically. The bone health of the semi-nomadic Ovahimba people of Namibia was investigated in the context of urbanization and changes of the sociocultural environment. Furthermore, data on bone health in SSA countries is scarce; there exists no ethnic-specific reference group for people of black origin. Included in the study were 98 urban and rural living Ovahimba people. Quantitative ultrasound was performed, sunrise/sunset saliva cortisol concentrations was measured and a questionnaire was conducted. There was no significant difference in the QUS parameters, however, after adjustment for confounders, SOS and SI differed significantly. The saliva cortisol concentrations differed significantly. After adjustment for confounders, saliva cortisol was significantly negatively correlated to SOS (r= -0.27, p = 0.021) giving an indication for an association between cortisol concentration and QUS parameters. The urban group furthermore showed a nutritional transition. Even though the bone health of the Ovahimba is very good, first signs of the adverse effects of urbanization were detected. Beside changes of lifestyle, this may be attributed to an increased cortisol exposure of the Ovahimba people living in an urban environment due to an increased psychosocial stress.

Tippens, Julie A

The global increase in refugee migration to urban areas creates challenges pertaining to the promotion of refugee health, broadly conceived. Despite considerable attention to trauma and forced migration, there is relatively little focus on how refugees cope with stressful situations, and on the determinants that facilitate and undermine resilience. This article examines how urban Congolese refugees in Kenya promote psychosocial well-being in the context of structural vulnerability. This article is based on interviews ( N = 55) and ethnographic participant observation with Congolese refugees over a period of 8 months in Nairobi in 2014. Primary stressors related to scarcity of material resources, political and personal insecurity, and emotional stress. Congolese refugees mitigated stressors by (a) relying on faith in God's plan and trust in religious community, (b) establishing borrowing networks, and (c) compartmentalizing the past and present. This research has broader implications for the promotion of urban refugees' psychosocial health and resilience in countries of first asylum.

Urban gully erosion and the SDGs: a case study from the Koboko rural town of Uganda

Zolezzi, Guido; Bezzi, Marco

2017-04-01

Urban gully erosion in developing regions has been addressed by the scientific community only recently, while it has been given much less attention in past decades. Nonetheless, recent examples show how relevant urban gully erosion in African towns of different sizes can be in terms of several Sustainable Development Goals, like goals 3 (good health and well being), 6 (clean water and sanitation) and 11 (sustainable cities and communities). The present work illustrate an example of gully erosion in the rapidly growing rural town of Koboko in NW Uganda close to the borders with Congo Democratic Republic and South Sudan. The research aims are (i) to develop a simple, low-cost methodology to quantify gully properties in data-scarce and resource-limited contexts, (ii) to quantify the main properties of and processes related to the urban gullies in the Koboko case study and (iii) to quantify the potential risk associated with urban gully erosion at the country scale in relation to rapid growth of urban centers in a sub-saharan African country. The methodology integrates collection of existing hydrological and land use data, rapid topographic surveys and related data processing, basic hydrological and hydro-morphological modeling, interviews to local inhabitants and stakeholders. Results indicate that Koboko may not represent an isolated hotspot of extensive urban gully development among rapidly growing small towns in Uganda, and, consequently, in countries with similar sustainable and human development challenges. Koboko, established two decades ago as a temporary war refugee camp, has been progressively established as a permanent urban settlement. The urban center is located on the top of an elongated hill and many of its recent neighbourhoods are expanding along the hill sides, where the local slope may reach considerable values, up to 10%. In the last ten years several gully systems with local depth up to 8 to 10 meters have been rapidly evolving especially following the construction of new roads and in the absence of a structured urban drainage plan. The deeper gullies are presently located in densely populated areas and present a variety of risks for people's livelihoods, including personal safety, risk of accidents for small vehicles (especially during night time), sanitation risk related with untreated domestic wastewater and uncontrolled garbage disposal into the deepest parts of the gullies. The methodology is easily repeatable and has the potential to quantify the fundamental properties of gully systems in contexts with scarce hydrological, soil and geomorphological local data availability and where the responsible agencies for urban planning and environmental protection are constrained by severe limitation in financial and human resources. For each gully system it allows to quantify total eroded volumes, length of the unstable gully reaches, time scale of development, drainage area and peak formative streamflow and also to provide process-based insight on the causes of gully development. The related knowledge base can be used to develop guidelines for urban growth aimed at minimizing the risk of gully erosion and related societal impacts.

High resolution weather data for urban hydrological modelling and impact assessment, ICT requirements and future challenges

ten Veldhuis, Marie-claire; van Riemsdijk, Birna

2013-04-01

Hydrological analysis of urban catchments requires high resolution rainfall and catchment information because of the small size of these catchments, high spatial variability of the urban fabric, fast runoff processes and related short response times. Rainfall information available from traditional radar and rain gauge networks does no not meet the relevant scales of urban hydrology. A new type of weather radars, based on X-band frequency and equipped with Doppler and dual polarimetry capabilities, promises to provide more accurate rainfall estimates at the spatial and temporal scales that are required for urban hydrological analysis. Recently, the RAINGAIN project was started to analyse the applicability of this new type of radars in the context of urban hydrological modelling. In this project, meteorologists and hydrologists work closely together in several stages of urban hydrological analysis: from the acquisition procedure of novel and high-end radar products to data acquisition and processing, rainfall data retrieval, hydrological event analysis and forecasting. The project comprises of four pilot locations with various characteristics of weather radar equipment, ground stations, urban hydrological systems, modelling approaches and requirements. Access to data processing and modelling software is handled in different ways in the pilots, depending on ownership and user context. Sharing of data and software among pilots and with the outside world is an ongoing topic of discussion. The availability of high resolution weather data augments requirements with respect to the resolution of hydrological models and input data. This has led to the development of fully distributed hydrological models, the implementation of which remains limited by the unavailability of hydrological input data. On the other hand, if models are to be used in flood forecasting, hydrological models need to be computationally efficient to enable fast responses to extreme event conditions. This presentation will highlight ICT-related requirements and limitations in high resolution urban hydrological modelling and analysis. Further ICT challenges arise in provision of high resolution radar data for diverging information needs as well as in combination with other data sources in the urban environment. Different types of information are required for such diverse activities as operational flood protection, traffic management, large event organisation, business planning in shopping districts and restaurants, timing of family activities. These different information needs may require different configurations and data processing for radars and other data sources. An ICT challenge is to develop techniques for deciding how to automatically respond to these diverging information needs (e.g., through (semi-)automated negotiation). Diverse activities also provide a wide variety of information resources that can supplement traditional networks of weather sensors, such as rain sensors on cars and social media. Another ICT challenge is how to combine data from these different sources for answering a particular information need. Examples will be presented of solutions are currently being explored.

This paper concerns people's assessment of their neighborhood of residence in a Chinese urban context. The aim of the study was to verify the factorial structure and the reliability of two instruments originally developed and validated in Italy (the full versions of the Perceived Residential Environment Quality Indicators [PREQIs] and of the Neighborhood Attachment Scale [NAS]) in a different cultural and linguistic context. The instruments consist of 11 scales measuring the PREQIs and one scale measuring neighborhood attachment (NA). The PREQIs scales include items covering four macroevaluative domains of residential environment quality: architectural and urban planning aspects (three scales: Architectural and Town-planning Space, Organization of Accessibility and Roads, Green Areas), sociorelational aspects (one scale: People and Social Relations), functional aspects (four scales: Welfare Services, Recreational Services, Commercial Services, and Transport Services), and contextual aspects (three scales: Pace of Life, Environmental Health, Upkeep and Care). The PREQIs and NAS were included in a self-report questionnaire, which had been translated and back-translated from English to Chinese, and was then administered to 340 residents in six districts (differing along various features) of a highly urbanized context in China, the city of Chongqing. Results confirmed the factorial structure of the scales and demonstrated good internal consistency of the indicators, thus reaffirming the results of previous studies carried out in Western urban contexts. The indicators tapping the neighborhood's contextual aspects (i.e., pace of life, environmental health, and upkeep) emerged as most correlated to NA. © 2015 The Institute of Psychology, Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

Epidemics and the politics of knowledge: contested narratives in Egypt's H1N1 response.

PubMed

Leach, Melissa; Tadros, Mariz

2014-01-01

This article explores the politics of knowledge involved in understanding and responding to epidemics in an era of global health governance and biosecurity. It develops and applies an approach focused on how multiple, competing narratives about epidemics are constructed, mobilized and interact, and selectively justify pathways of intervention and response. A detailed ethnographic case study of national and local responses to H1N1 influenza, so-called swine flu, in Egypt reveals how global narratives were reworked by powerful actors in a particular political context, suppressing and delegitimizing the alternative narratives of the Zabaleen (Coptic Christian) people whose lives and livelihoods centered on raising pigs and working with them to control urban waste. The case study illustrates important ways in which geographies and politics of blame around epidemics emerge and are justified, their political contexts and consequences, and how they may feed back to shape the dynamics of disease itself.

GENIUS: A tool for multi-disciplinary and multi-scalar databases

Cities are responsible for the majority of energy consumption on the planet. As a consequence, researches regarding energy use in urban context have been increasing for the last decades. Recently the interrelationship between city, energy consumption and urban microclimate appeared as a key component of urban sustainability. To be accurate, those studies must take into account a multidisciplinary urban context and modelling tools need high definition data. Nevertheless, at the city scale, input data is either imprecise or only available for small areas. In particular, there is a lack of information about buildings footprints, roofs sloping, envelope materials, etc. Moreover, the existing data do not allow researchers to explore prospective issues such as climate change or future urban development. In this sense, we developed a new tool called GENIUS (GENerator of Interactive Urban blockS) to build high definition and evolutionary maps from available databases. GENIUS creates maps composed of archetypical neighbourhood coming as shape-files of polygons with additional information (height, age, use, thermal insulation, etc.). Those archetypical neighbourhoods come to seven types of urban blocks that can be found in most European cities. Those types can be compared with Stewart and Oke Local Climate Zones (LCZ). The first step of our method is to transform an existing map into an 'archetypical map'. To do this, the urban database of the IGN (French Geographical Institute) was used. The maps were divided into cells of 250 meters resolution. For each cell, about 40 morphological indicators were calculated. Seven groups of blocks were then identified by means of Principal Component Analysis. GENIUS databases are also able to evolve through time. As a matter of fact, the initial map is transformed, year after year, by taking into account changes in density and urban history. In that sense, GENIUS communicates with NEDUM, a model developed by the CIRED (International Centre for Environment and Development), that simulates the spread of the city and provides information on build density. Under the influence of those density evolutions and of different urban planning scenarios, GENIUS changes the type of urban blocks and their parameters (height, plot ratio, thermal properties, etc.). The paper will present the validation of GENIUS and its application on the French city of Toulouse. Six scenarios have been designed taking into account demographic evolutions, economic contexts and urban planning policies. For each of those scenarios, we generated maps of the city and its surroundings from 2010 to 2100. The obtained maps enabled us to come up with simulations of Toulouse energy consumptions and microclimate both present and future.

Carbon reduction at the household level is an integral part of carbon mitigation. This study analyses the characteristics, effects, contributing factors and policies for urban household carbon emissions in the Yangtze River Delta of China. Primary data was collected through structured questionnaire surveys in three cities in the region – Nanjing, Ningbo, and Changzhou in 2011. The survey data was first used to estimate the magnitude of household carbon emissions in different urban contexts. It then examined how, and to what extent, each set of demographic, economic, behavioral/cognitive and spatial factors influence carbon emissions at the household level. The average of urban household carbon emissions in the region was estimated to be 5.96 tonnes CO2 in 2010. Energy consumption, daily commuting, garbage disposal and long-distance travel accounted for 51.2%, 21.3%, 16.0% and 11.5% of the total emission, respectively. Regulating rapidly growing car-holdings of urban households, stabilizing population growth, and transiting residents’ low-carbon awareness to household behavior in energy saving and other spheres of consumption in the context of rapid population aging and the growing middle income class are suggested as critical measures for carbon mitigation among urban households in the Yangtze River Delta.

Urbanization Impacts on River Landscapes in a Global Context

Chin, A.

2005-12-01

A half century ago, Strahler (1956) and Leopold (1956) pointed attention to the reality of human impacts on river systems, outlining erosion and aggradation as system responses when steady state is disturbed by human activity, and linking river channel adjustments to changes in sediment yield owing to land use alterations. Significant advances have been made along these lines in the years since, with intensified research efforts producing a voluminous literature documenting a range of human impacts on fluvial geomorphology. This paper summarizes the progress made on understanding the impacts of urban development on river landscapes, with emphasis on the distribution of such impacts in a global context. Drawing from a database developed from published literature representing a range of world areas, the analysis quantifies the magnitude and direction of urban-induced change in a comparative context, evaluates how impacts vary with locale and scale, and assesses the persistence of such impacts across locales and scales. Results indicate high variability both in magnitude and persistence of impacts. The spatial distribution of research investigations has also been markedly uneven, with input to theory development having come from a limited number of sites. Substantial areas across the earth surface remain blind spots in this context; future investigations might serve the science best if they are conducted in some of these locations.

Social capital is essential for the successful development of young people. The current study examines direct measures of social capital in young people in five urban global contexts. The Well-Being of Adolescents in Vulnerable Environments is a global study of young people aged 15-19 years living in disadvantaged, urban settings. Respondent-driven sampling was used to recruit approximately 500 participants from each site. The sample included 2,339 young people (mean age 16.7 years; 47.5% female). We examined the associations between social capital in four domains-family, school, peers, and neighborhood and demographic characteristics-using gender-stratified ordinary least-squares regression. We also examined associations between self-reported health and the four social capital domains, which was minimal. School enrollment was positively associated with social capital for young women in Baltimore, Delhi, and Shanghai; the association was less consistent for young men. The same pattern is true for perceived wealth. Unstable housing was associated with low familial social capital in all groups except young women in Shanghai and young men in Ibadan and Johannesburg. Being raised outside a two-parent family has a widespread, negative association with social capital. Self-reported health had a mainly positive association with social capital with the most consistent association being neighborhood social capital. Different types of social capital interact with social contexts and gender differently. Strategies that aim to build social capital as part of risk reduction and positive youth development programming need to recognize that social capital enhancement may work differently for different groups and in different settings.

The British Association for the Advancement of Science sought to promote the understanding of science in various ways, principally by having annual meetings in different towns and cities throughout Britain and Ireland (and, from 1884, in Canada, South Africa and Australia). This paper considers how far the location of its meetings in different urban settings influenced the nature and reception of the association's activities in promoting science, from its foundation in 1831 to the later 1930s. Several themes concerning the production and reception of science--promoting, practising, writing and receiving--are examined in different urban contexts. We consider the ways in which towns were promoted as venues for and centres of science. We consider the role of local field sites, leading local practitioners and provincial institutions for science in attracting the association to different urban locations. The paper pays attention to excursions and to the evolution and content of the BAAS meeting handbook as a 'geographical' guide to the significance of the regional setting and to appropriate scientific venues. The paper considers the reception of BAAS meetings and explores how far the association's intentions for the promotion of science varied by location and by section within the BAAS. In examining these themes--the geographical setting of the association's meetings, the reception of association science in local civic and intellectual context and the importance of place to an understanding of what the BAAS did and how it was received--the paper extends existing knowledge of the association and contributes to recent work within the history of science which has emphasized the 'local' nature of science's making and reception and the mobility of scientific knowledge.

Coping with heat in the city: what can we learn from a survey immediately after a hot weather period for future heat waves?

Karlsruhe is one of the hottest cities in Germany with a temperature record of 40.2°C in August 2003. In 2013, two hot weather periods with continuous heat warnings by the German Weather Service for 7 and 8 days occurred during the second half of July and first 10 days of August 2013, and in early August the temperatures in Karlsruhe almost reached again the record of 40.2°C. To understand how citizens experienced the heat and what strategies they used to cope with the heat, we conducted a questionnaire survey on subjective heat stress and coping strategies immediately after the hot weather period. Based on a holistic approach the questionnaire included questions on heat stress experience in different contexts of daily life, health impacts of the heat, coping measures, housing conditions, urban environment, living conditions, and socio-demographic characteristics. The responses of the 323 survey participants living and working in Karlsruhe show that they on average experienced the heat as rather stressful event, whereby the heat stress experienced at home was significant lower than heat stress experienced at work or in general. Regression analyses show that, among the factors included in the questionnaire, the health impairments suffered during the heat, the control belief and the coping measures implemented mainly determine heat stress experienced in general and at work. For the subjective heat stress at home, factors of the built urban environment such as heat loading of district, living in the attic or the ground floor, and heat protection elements of the inhabited building also played a role. At the same time, the way the respondents used different coping strategies in context of their daily activities and routines during heat suggests lessons to learn from this event how individual response to heat differs from responses to other types of natural hazards.

The relevance of simulation as a teaching tool for medical professionals working in rural and remote contexts is apparent when low-frequency, high-risk situations are considered. Simulation training has been shown to enhance learning and improve patient outcomes in urban settings. However, there are few simulation scenarios designed to teach rural trauma management during complex medical transportation. In this technical report, we present a scenario using a medevac helicopter (Replica of Sikorsky S-92 designed by Virtual Marine Technology, St. John's, NL) at a rural community. This case can be used for training primary care physicians who are working in a rural or remote setting, or as an innovative addition to emergency medicine and pre-hospital care training programs.

Active commuting to work (ACW) is beneficial to traffic, environment and population health. More evidence is needed on effective ways to promote ACW. This paper describes the protocol and baseline findings of a cluster-randomized controlled study, which aims to promote ACW with multilevel strategies in two large workplace areas in Tampere, Finland. In Phase 1, the impacts of environmental strategies (trail improvements) were evaluated in 11 workplaces within Area 1. In Phase 2, five more workplaces were recruited from Area 2 to evaluate the impacts of social and behavioral strategies customized for each workplace. For this purpose, the workplaces in both areas were randomly assigned into experimental group (EXP, n = 6 + 2), which promoted ACW with social and behavioral strategies or into comparison group (COM, n = 5 + 3), which participated in the data collection only. The primary indicator in both phases is the change in employees’ ACW. Secondary indicators are e.g., changes in employees’ self-rated health, wellbeing at work, restrictions to and motivation for ACW, adverse effects due to ACW and the use and quality of the main walking and cycling trails. Also process, efficiency and environmental evaluation is included. The study is the first one in Finland to combine interdisciplinary collaboration between practitioners and researchers working in the fields of transportation, urban design, physical activity and sustainable development to promote ACW. The findings benefit all stakeholders interested in promoting ACW in urban context.

Considering risk contexts in explaining the paradoxical HIV increase among female sex workers in Mumbai and Thane, India.

The period 2006-2009 saw intensive scale-up of HIV prevention efforts and an increase in reported safer sex among brothel and street-based sex workers in Mumbai and Thane (Maharashtra, India). Yet during the same period, the prevalence of HIV increased in these groups. A better understanding of sex workers' risk environment is needed to explain this paradox. In this qualitative study we conducted 36 individual interviews, 9 joint interviews, and 10 focus group discussions with people associated with HIV interventions between March and May 2012. Dramatic changes in Mumbai's urban landscape dominated participants' accounts, with dwindling sex worker numbers in traditional brothel areas attributed to urban restructuring. Gentrification and anti-trafficking efforts explained an escalation in police raids. This contributed to dispersal of sex work with the sex-trade management adapting by becoming more hidden and mobile, leading to increased vulnerability. Affordable mobile phone technology enabled independent sex workers to trade in more hidden ways and there was an increased dependence on lovers for support. The risk context has become ever more challenging, with animosity against sex work amplified since the scale up of targeted interventions. Focus on condom use with sex workers inadvertently contributed to the diversification of the sex trade as clients seek out women who are less visible. Sex workers and other marginalised women who sell sex all strictly prioritise anonymity. Power structures in the sex trade continue to pose insurmountable barriers to reaching young and new sex workers. Economic vulnerability shaped women's decisions to compromise on condom use. Surveys monitoring HIV prevalence among 'visible' street and brothel-bases sex workers are increasingly un-representative of all women selling sex and self-reported condom use is no longer a valid measure of risk reduction. Targeted harm reduction programmes with sex workers fail when implemented in complex urban environments that favour abolition. Increased stigmatisation and dispersal of risk can no longer be considered as unexpected. Reaching the increasing proportion of sex workers who intentionally avoid HIV prevention programmes has become the main challenge. Future evaluations need to incorporate building 'dark logic' models to predict potential harms.

Motivations for Prescription Drug Misuse among Young Adults: Considering Social and Developmental Contexts.

LeClair, Amy; Kelly, Brian C; Pawson, Mark; Wells, Brooke E; Parsons, Jeffrey T

As part of a larger study on prescription drug misuse among young adults active in urban nightlife scenes, we examined participants' motivations for misuse. Prescription painkillers, stimulants and sedatives were the primary substances of interest. Participants were recruited from nightlife venues in New York using time-space sampling. Subjects completed a mixed-methods assessment at project research offices. The data presented here are from a subsample of 70 qualitative interviews conducted during the baseline assessment. We identified experimentation and a "work hard, play hard" ethos as key motivations for misusing prescription drugs and argue that these motivations are specific, though not necessarily unique, to the participants' social location as young adults. These findings highlight the role of life stage and social context in the misuse of prescription drugs. Future studies of prescription drug misuse should pay attention to the larger social contexts in which users are embedded and, therefore, make decisions about how and why to misuse. Moving beyond the very broad concepts of "recreation" and "self-medication" presently established in the research, policies targeting young adults may want to tailor intervention efforts based on motivations.

Structure of a forested urban park: implications for strategic management.

Informed management of urban parks can provide optimal conditions for tree establishment and growth and thus maximize the ecological and aesthetic benefits that trees provide. This study assesses the structure, and its implications for function, of the urban forest in Allan Gardens, a 6.1 ha downtown park in the City of Toronto, Canada, using the Street Tree Resource Analysis Tool for Urban Forest Managers (STRATUM). Our goal is to present a framework for collection and analysis of baseline data that can inform a management strategy that would serve to protect and enhance this significant natural asset. We found that Allan Garden's tree population, while species rich (43), is dominated by maple (Acer spp.) (48% of all park trees), making it reliant on very few species for the majority of its ecological and aesthetic benefits and raising disease and pest-related concerns. Age profiles (using size as a proxy) showed a dominance of older trees with an inadequate number of individuals in the young to early middle age cohort necessary for short- to medium-term replacement. Because leaf area represents the single-most important contributor to urban tree benefits modelling, we calculated it separately for every park tree, using hemispheric photography, to document current canopy condition. These empirical measurements were lower than estimates produced by STRATUM, especially when trees were in decline and lacked full canopies, highlighting the importance of individual tree condition in determining leaf area and hence overall forest benefits. Stewardship of natural spaces within cities demands access to accurate and timely resource-specific data. Our work provides an uncomplicated approach to the acquisition and interpretation of these data in the context of a forested urban park. Copyright 2010 Elsevier Ltd. All rights reserved.

Climate change is widely considered one of the greatest challenges to global sustainability, with extreme events being the most immediate way that people experience this phenomenon. Urban areas are particularly vulnerable to these events given their location, concentration of people, and increasingly complex and interdependent infrastructure. We are developing a conceptual framework for urban social-ecological-technological systems (SETS) that will allow researchers and practitioners to assess how infrastructure can be resilient, provide ecosystem services, improve social well being, and exploit new technologies in ways that benefit urban populations. The framework integrates the three domains of social and equity issues, environmental quality and protection, and technical/engineering aspects, to form a concept of infrastructure that occurs at the intersection of the domains. Examples show how the more common socioecological systems and socially sensitive engineering approaches that fail to incorporate the third dimension may elevate vulnerability to climate-related disaster. The SETS conceptual framework bridges currently siloed social science, environmental science, and engineering approaches to significantly advance research into the structure, function, and emergent properties of SETS. Extreme events like heat waves in Phoenix; coastal and urban flooding in the wake of superstorm Sandy and following hurricanes in Miami, FL; drought in Mexico; and urban flooding in Baltimore, Portland, San Juan PR, Syracuse, and Valdivia, Chile provide examples of the impacts of and vulnerability to extreme events that demand a new approach. The infrastructure of the future must be resilient, leverage ecosystem services, improve social well being, and exploit new technologies in ways that benefit all segments of urban populations and are appropriate to the particular urban contexts. These contexts are defined not only by the biophysical environment but also by culture and institutions of each place. We apply the SETS conceptual framework to nine western hemisphere cities in diverse settings, presenting hypotheses about the relative efficacy of strategies for resilient SETS infrastructure in cities contrasting in event type, biophysical setting, and cultural and institutional contexts.

Urban vegetation and thermal patterns following city growth in different socio-economic contexts

Urban expansion accompanied by losses of vegetated spaces and their ecological services raises significant concerns about the future of humans in metropolitan "habitats". Despite recent growth of urban studies globally, it is still not well understood how environmental effects of urbanization vary with the rate and socioeconomic context of development. Our study hypothesized that with urban development, spatial patterns of surface thermal properties and green plant cover would shift towards higher occurrence of relatively warmer and less vegetated spaces such as built-up areas, followed by losses of greener and cooler areas such as urban forests, and that these shifts would be more pronounced with higher rate of economic and/or population growth. To test these ideas, we compared 1992-2011 changes in remotely sensed patterns of green vegetation and surface temperature in three example cities that experienced peripheral growth under contrasting socio-economic context - Dallas, TX, USA, Beijing, China and Kyiv, Ukraine. To assess their transformation, we proposed a metric of thermal-vegetation angle (TVA) estimated from per-pixel proxies of vegetation greenness and surface temperature from Landsat satellite data and examined changes in TVA distributions within each city's core and two decadal zones of peripheral sprawl delineated from nighttime satellite data. We found that higher economic and population growth were coupled with more pronounced changes in TVA distributions, and more urbanized zones often exhibited higher frequencies of warmer, less green than average TVA values with novel patterns such as "cooler" clusters of building shadows. Although greener and cooler spaces generally diminished with development, they remained relatively prevalent in low-density residential areas of Dallas and peripheral zones of Kyiv with exurban subsistence farming. Overall, results indicate that the effects of modified green space and thermal patterns within growing cities highly vary depending on economy, population trends and historical legacies of planned green spaces. Remote sensing-based metrics such as TVA facilitate their comparisons and offer useful strategies to cost-effectively monitor urban transformation and inform more explicit environmental modeling of cities in the future.

The nurse work environment, job satisfaction and turnover rates in rural and urban nursing units.

Baernholdt, Marianne; Mark, Barbara A

2009-12-01

The aim of the present study was to determine whether there are differences in hospital characteristics, nursing unit characteristics, the nurse work environment, job satisfaction and turnover rates in rural and urban nursing units. Research in urban hospitals has found an association between the nurse work environment and job satisfaction and turnover rates, but this association has not been examined in rural hospitals. Rural and urban nursing units were compared in a national random sample of 97 United States hospitals (194 nursing units) with between 99 and 450 beds. Significant differences were found between hospital and nursing unit characteristics and the nurse work environment in rural and urban nursing units. Both nursing unit characteristics and the work environment were found to have a significant influence on nurse job satisfaction and turnover rates. Job satisfaction and turnover rates in rural and urban nursing units are associated with both nursing unit characteristics and the work environment. Both rural and urban hospitals can improve nurse job satisfaction and turnover rates by changing unit characteristics, such as creating better support services and a work environment that supports autonomous nursing practice. Rural hospitals can also improve the work environment by providing nurses with more educational opportunities.

Estimating the influence of different urban canopy cover types on atmospheric particulate matter (PM10) pollution abatement in London UK.

2010-05-01

In the urban environment atmospheric pollution by PM10 (particulate matter with a diameter less than 10 x 10-6 m) is a problem that can have adverse effects on human health, particularly increasing rates of respiratory disease. The main contributors to atmospheric PM10 in the urban environment are road traffic, industry and power production. The urban tree canopy is a receptor for removing PM10s from the atmosphere due to the large surface areas generated by leaves and air turbulence created by the structure of the urban forest. In this context urban greening has long been known as a mechanism to contribute towards PM10 removal from the air, furthermore, tree canopy cover has a role in contributing towards a more sustainable urban environment. The work reported here has been carried out within the BRIDGE project (SustainaBle uRban plannIng Decision support accountinG for urban mEtabolism). The aim of this project is to assess the fluxes of energy, water, carbon dioxide and particulates within the urban environment and develope a DSS (Decision Support System) to aid urban planners in sustainable development. A combination of published urban canopy cover data from ground, airborne and satellite based surveys was used. For each of the 33 London boroughs the urban canopy was classified to three groups, urban woodland, street trees and garden trees and each group quantified in terms of ground cover. The total [PM10] for each borough was taken from the LAEI (London Atmospheric Emissions Inventory 2006) and the contribution to reducing [PM10] was assessed for each canopy type. Deposition to the urban canopy was assessed using the UFORE (Urban Forest Effects Model) approach. Deposition to the canopy, boundary layer height and percentage reduction of the [PM10] in the atmosphere was assessed using both hourly meterological data and [PM10] and seasonal data derived from annual models. Results from hourly and annual data were compared with measured values. The model was then applied to future predictions of annual [PM10] and future canopy cover scenarios for London. The contribution of each canopy type subjected to the different atmospheric [PM10] of the 33 London boroughs now and in the future will be discussed. Implementing these findings into a decision support system (DSS) for sustainable urban planning will also be discussed.

This study aimed to describe the workings of an urban male remand prison mental health service exploring the key challenges and successes, levels of integration and collaboration with other services. A purposive sampling was used to recruit key prison and healthcare professionals for in-depth interviews. A thematic analysis was used to analyse transcripts based on an initial coding frame of several predefined themes. Other key themes were also identified. Twenty-eight interviews were conducted. Prisoners referred to the service had complex, sometimes acute mental illness requiring specialist assessment and treatment. Key successes of the in-reach service included the introduction of an open referral system, locating a mental health nurse at reception to screen all new prisoners and a zoning system to prioritise urgent or non-urgent cases. Achieving an integrated system of healthcare was challenging because of the numerous internal and external services operating across the prison, a highly transient population, limited time and space to deliver services and difficulties with providing inpatient care (e.g., establishing the criteria for admission and managing patient flow). Collaborative working between prison and healthcare staff was required to enable best care for prisoners. The prison mental health in-reach service worked well in assessing and prioritising those who required specialist mental health care. Although the challenges of working within the prison context limited what the in-reach team could achieve. Further work was needed to improve the unit environment and how best to target and deliver inpatient care within the prison.

Urban Health Equity Assessment and Response Tool (HEART) is a tool developed by the World Health Organization whose objective is to provide evidence on urban health inequalities so as to help to decide the best interventions aimed to promote urban health equity. The aim of this paper is to describe the experience of implementing Urban HEART in Barcelona city, both the adaptation of Urban HEART to the city of Barcelona, its use as a means of identifying and monitoring health inequalities among city neighbourhoods, and the difficulties and barriers encountered throughout the process. Although ASPB public health technicians participated in the Urban HEART Advisory Group, had large experience in health inequalities analysis and research and showed interest in implementing the tool, it was not until 2015, when the city council was governed by a new left-wing party for which reducing health inequalities was a priority that Urban HEART could be used. A provisional matrix was developed, including both health and health determinant indicators, which allowed to show how some neighbourhoods in the city systematically fare worse for most of the indicators while others systematically fare better. It also allowed to identify 18 neighbourhoods-those which fared worse in most indicators-which were considered a priority for intervention, which entered the Health in the Barcelona Neighbourhoods programme and the Neighbourhoods Plan. This provisional version was reviewed and improved by the Urban HEART Barcelona Working Group. Technicians with experience in public health and/or in indicator and database management were asked to indicate suitability and relevance from a list of potential indicators. The definitive Urban HEART Barcelona version included 15 indicators from the five Urban HEART domains and improved the previous version in several requirements. Several barriers were encountered, such as having to estimate indicators in scarcely populated areas or finding adequate indicators for the physical context domain. In conclusion, the Urban HEART tool allowed to identify urban inequalities in the city of Barcelona and to include health inequalities in the public debate. It also allowed to reinforce the community health programme Health in the Barcelona Neighbourhoods as well as other city programmes aimed at reducing health inequalities. A strong political will is essential to place health inequalities in the political agenda and implement policies to tackle them.

Urban Heat Island in the city of Bari (Italy) ant its relationship with morphological features

NASA Astrophysics Data System (ADS)

Ceppi, C.; Balena, P.; Loconte, P.; Mancini, F.

2012-04-01

The investigation of an Urban Heat Island (UHI) and its relationship with the wide range of factors able to explain its behavior is a very difficult task: the main trouble is represented by the spatial variability of the urban temperature due to the extreme heterogeneousness of the urban coverage and morphological features. In literature it is known that the local surface temperatures are influenced by the changing characteristics in urban surface and modification of land surface processes affecting the surface energy balance and the shape of boundary layer. The whole processes could lead to distinct urban climates. This work is mainly focused on the mechanisms which are actually connecting the urban morphology with the surface temperature as derived by satellite data provided from the ASTER sensor. Urban morphology could be described by several factors depending on the selected scale of analysis. At the macroscale the UHI is more related to the land-use, environmental context and boundary conditions. At the microscale the surface characteristics, urban density, ratio between green and built areas and, construction and built typology are more involved in addition to the composite indicators such as the Sky View factor and the elevation of the built texture. The case study of the city of Bari is faced. It is a medium sized city in the southern Italy, characterized by the presence of a pervasive waterfront and presence of "lame", a natural erosive furrows shallow that are typical of the Apulia country side. Such ephemeral streams convey the stormwater from the plateau of the hilly Murgia areas to the sea. Moreover, the urban complexity of the city exacerbates the spatial variability of the phenomenon. The first step aim at the investigating of the relationship between the thermal behavior and the above mentioned factors by the construction of a set of homogeneous morphological units. The classification is built both in the urban and rural zone. The second step focuses on the development of a spatial statistical analysis based on qualitative and quantitative indicators able to link the classes of urban morphology with the satellite-based surface temperature. The relationships highlighted by such a spatial analysis can be used to model the urban climate and, consequently, develop a new kind of planning more addressed towards the mitigation of the UHI phenomenon.

Urban hydrogeology in Indonesia: A highlight from Jakarta

NASA Astrophysics Data System (ADS)

Lubis, R. F.

2018-02-01

In many cities in the developing countries, groundwater is an important source of public water supply. The interaction between groundwater systems and urban environments has become an urgent challenge for many developing cities in the world, Indonesia included. Contributing factors are, but not limited to, the continuous horizontal and vertical expansion of cities, population growth, climate change, water scarcity and groundwater quality degradation. Jakarta as the capital city of Indonesia becomes a good example to study and implement urban hydrogeology. Urban hydrogeology is a science for investigating groundwater at the hydrological cycle and its change, water regime and quality within the urbanized landscape and zones of its impact. The present paper provides a review of urban groundwater studies in Jakarta in the context of urban water management, advances in hydrogeological investigation, monitoring and modelling since the city was established. The whole study emphasizes the necessity of an integrated urban groundwater management and development supporting hydrogeological techniques for urban areas.

There is a fundamental need for the professional community to cultivate and nurture active relationships with amateur organizations. The rewards of such work are highly beneficial to general public education and town-gown relations, but are time-consuming and hard-won. New York City and the surrounding area is both ideally suited and unambiguously ill-suited for astronomy public outreach. I will detail the results of three major outreach efforts in coordination with the Amateur Astronomers Association of New York. I will highlight large public-space observing in the context of the Transit of Venus and star parties at other locations. I will also outline outreach efforts at William Paterson University, where two public nights and a Curiosity EDL event created a clear impact in Northern New Jersey. I will detail methods for encouraging and bringing out amateur observers to events, urban crowd management, publicity issues, and the benefits and pitfalls of social media in the promotion and execution of large-scale and moderate events.

Although adverse birth outcomes have been associated with neighbourhood deprivation in urban areas, few studies have addressed this issue in rural zones. This study examines whether associations between neighbourhood deprivation and adverse birth outcomes differ in urban and rural contexts, while taking individual characteristics and spatial accessibility of prenatal care (SAPC) into account. Pregnant women from a French mother-child cohort were recruited from 2002 to 2006 in Brittany. Their residential addresses were geocoded into their census blocks (the finest geographical resolution available). Deprivation was assessed at the same neighbourhood level. Models to assess the associations of deprivation, stratified by urban/rural status, with preterm delivery (PTD), with small for gestational age birth weight (SGA) and with small for gestational age head circumference at birth (SHC), estimated odds ratios (ORs), adjusted for maternal socioeconomic characteristics and SAPC. This study considered 2929 liveborn singleton pregnancies from 780 census blocks. Neighbourhood deprivation was associated with increased risks of SGA and SHC (P trend < 0.01 and 0.03 respectively), only among mothers residing in rural areas. Neighbourhood deprivation had statistically significantly heterogeneous effects on SGA and SHC according to the urban/rural status of maternal residence. These findings suggest that neighbourhood deprivation affects fetal growth differentially in urban and rural areas and that SAPC does not seem to be responsible for this difference. Comparison of these findings with the literature requires caution in the conceptualisation of urban and rural settings. © 2015 John Wiley & Sons Ltd.

Ling, Sara; Watson, Alison; Gehrs, Margaret

Clients with substance use disorders access care in all areas of the health care system, yet the Canadian nursing literature lacks content on the knowledge, skills, and judgment needed by nurses who work with this population. To address this literature gap, two Advanced Practice Nurses adapted the Canadian Centre on Substance Abuse's Technical Competencies for Canada's Substance Abuse Workforce to include nursing content and theory. This article describes the adaptation process and validation method used by the Advanced Practice Nurses at a large, Canadian urban teaching hospital and includes discussion about actual and potential opportunities for practical application of the adapted framework.

Plant pollinator networks along a gradient of urbanisation.

Geslin, Benoît; Gauzens, Benoit; Thébault, Elisa; Dajoz, Isabelle

2013-01-01

Habitat loss is one of the principal causes of the current pollinator decline. With agricultural intensification, increasing urbanisation is among the main drivers of habitat loss. Consequently studies focusing on pollinator community structure along urbanisation gradients have increased in recent years. However, few studies have investigated how urbanisation affects plant-pollinator interaction networks. Here we assessed modifications of plant-pollinator interactions along an urbanisation gradient based on the study of their morphological relationships. Along an urbanisation gradient comprising four types of landscape contexts (semi-natural, agricultural, suburban, urban), we set up experimental plant communities containing two plant functional groups differing in their morphological traits ("open flowers" and "tubular flowers"). Insect visitations on these communities were recorded to build plant-pollinator networks. A total of 17 857 interactions were recorded between experimental plant communities and flower-visitors. The number of interactions performed by flower-visitors was significantly lower in urban landscape context than in semi-natural and agricultural ones. In particular, insects such as Syrphidae and solitary bees that mostly visited the open flower functional group were significantly impacted by urbanisation, which was not the case for bumblebees. Urbanisation also impacted the generalism of flower-visitors and we detected higher interaction evenness in urban landscape context than in agricultural and suburban ones. Finally, in urban context, these modifications lowered the potential reproductive success of the open flowers functional group. Our findings show that open flower plant species and their specific flower-visitors are especially sensitive to increasing urbanisation. These results provide new clues to improve conservation measures within urbanised areas in favour of specialist flower-visitors. To complete this functional approach, studies using networks resolved to the species level along urbanised gradients would be required.

As the world's biggest economy, China is becoming the biggest consumer of resources globally. Given this trend, the over-proportional fast increase in urbanization presents China with fundamental problems. Among the most urgent ones is the increasing loss of agricultural land as urbanization takes place in the most productive regions along the coast. The latter is being responsible for a shift in agriculture production towards climatically less favorable areas. At the same time, the loss of green areas in and around growing cities is increasing the effect of the urban heat island. The perception of the potential risks related to this phenomenon, in the context of climate change, has led the Shanghai city administration to increase its urban-greening efforts, expanding the per capita area of green from 1m2 in 1990 to 12.5m2 in 2008. In this context, this paper aims at identifying the influence of urban and peri-urban agriculture (UPA) on the sustainability of the urban regions of Shanghai and Nanjing. In particular, it focuses on the effects of UPA on the greenhouse gas (GHG) emissions, soil nutrients and water balances, local climate and the structure and functions of the urbanized areas. We propose an interdisciplinary framework combining remote sensing, model simulations and GHG field observations and targeted at identifying "win-win" strategies for sustainable planning pathways showing high potentials for UPA. The framework is based on spatial scenario modeling, automatic classification of urban structure types and on a prototype of a high-quality spatial database consisting of a 3D city model. Dynamic boundary conditions for climate and urban development are provided by state of the art models. These approaches meet the needs of stakeholders and planners in China. A special emphasis is put on interdependencies between small holder farming in the urban and peri-urban zone and climate change adaptation and mitigation strategies focusing on improved management of local water and nutrient cycles. The whole database generated will be structured and made accessible for planners and stakeholders in the form of a 3D city visualization model.

The notions of resilience in spatial planning for drought - flood coexistence (DFC) at regional scale

Trong Hoa, Nguyen; Vinh, Nguyen Quoc

2018-04-01

The notions of urban resilience and resilient city has been developed in the 2000s [1], four decades since the first concept of ecological resilience was originally introduced in the 1970s by ecologist C.S. Holling [2]. However, they have attracted great attentions and interests, in both academia and urban governance, then in planning practice over recent years. The first two sections of this paper examine the term resilience in ecological systems, urban systems, in spatial planning and in urban design. Specific attention of the paper, introduced in the third part, is to investigate resilience in the context of drought-flood coexistence (DFC), revolving two key objects and their interactions: DFC and urban at regional scale. Flood and drought events, in their turns intertwine in natural correlation, which is also reviewed. These relationships are literally investigated, to prove that they interplay mutually with each other, and that once a city develops in relation with water cycle at a regional context, in arid zone, not only hydrological drought could be regionally decreased, but human-induced floods could be ecologically regulated. The study concludes in the fourth, together with lessons from relevant case studies in America, China, with some principles on spatial planning, resilient/adaptive to DFC, which could be ecologically managed in correlation with urban development on a sustainable pathway.

Urbanism and the division of labour in the Roman Empire

PubMed Central

Ortman, S. G.; Lobo, J.

2017-01-01

One of the hallmarks of human agglomeration is an increase in the division of labour, but the exact nature of this relationship has been debated among anthropologists, sociologists, economists, and historians and archaeologists. Over the last decade, researchers investigating contemporary urban systems have suggested a novel explanation for the links between the numbers of inhabitants in settlements and many of their most important characteristics, which is grounded in a view of settlements as social networks embedded in built environments. One of the remarkable aspects of this approach is that it is not based on the specific conditions of the modern world (such as capitalism or industrialization), which raises the issue of whether the relationships observed in contemporary urban systems can also be detected in pre-modern urban or even non-urban systems. Here, we present a general model for the relationship between the population and functional diversity of settlements, where the latter is viewed as an indicator of the division of labour. We then explore the applicability of this model to pre-modern contexts, focusing on cities in the Roman Empire, using estimates of their numbers of inhabitants, numbers of documented professional associations, and numbers of recorded inscriptions to develop an index of functional diversity. Our results are consistent with theoretical expectations, adding further support to the view that urban systems in both contemporary and pre-modern contexts reflect a common set of generative processes.

Forensic nursing and the palliative approach to care: an empirical nursing ethics analysis.

PubMed

Wright, David Kenneth; Vanderspank-Wright, Brandi; Holmes, Dave; Skinner, Elise

2017-08-02

A movement is underway to promote a palliative approach to care in all contexts where people age and live with life-limiting conditions, including psychiatric settings. Forensic psychiatry nursing-a subfield of mental health nursing- focuses on individuals who are in conflict with the criminal justice system. We know little about the values of nurses working in forensic psychiatry, and how these values might influence a palliative approach to care for frail and aging patients. Interviews with four nurses working on one of two forensic units of a university-affiliated mental health hospital in an urban area of eastern Canada. Three specific values were found to guide forensic nurses in their care of aging patients that are commensurate with a palliative approach: hope, inclusivity, and quality of life. When we started this project, we wondered whether the culture of forensic nursing practice was antithetical to the values of a palliative approach. Instead, we found several parallels between forensic nurses' moral identities and palliative philosophy. These findings have implications for how we think about the palliative approach in contexts not typically associated with palliative care, but in which patients will increasingly age and die.

The paper critically examines the understanding, approach and indicators that have been used to measure the degree of disparity. It is fact that disparity exists everywhere. However, this paper highlights on disparities existing between rural and urban areas. In this context, it talks about 'whyí and 'howí disparities exist between rural and urban areas. The study suggests that 'incomeí is not a sufficient indicator to capture the magnitude of disparities at any level. It is, therefore, necessary to develop some indicators representing human resource development and infrastructure facility to understand the growing rural-urban disparity in India.

Urban forests and pollution mitigation: analyzing ecosystem services and disservices.

PubMed

Escobedo, Francisco J; Kroeger, Timm; Wagner, John E

2011-01-01

The purpose of this paper is to integrate the concepts of ecosystem services and disservices when assessing the efficacy of using urban forests for mitigating pollution. A brief review of the literature identifies some pollution mitigation ecosystem services provided by urban forests. Existing ecosystem services definitions and typologies from the economics and ecological literature are adapted and applied to urban forest management and the concepts of ecosystem disservices from natural and semi-natural systems are discussed. Examples of the urban forest ecosystem services of air quality and carbon dioxide sequestration are used to illustrate issues associated with assessing their efficacy in mitigating urban pollution. Development of urban forest management alternatives that mitigate pollution should consider scale, contexts, heterogeneity, management intensities and other social and economic co-benefits, tradeoffs, and costs affecting stakeholders and urban sustainability goals.

Soft systems methodology and the ecosystem approach: a system study of the Cooum River and environs in Chennai, India.

PubMed

Bunch, Martin J

2003-02-01

This paper discusses the integration of soft systems methodology (SSM) within an ecosystem approach in research to support rehabilitation and management of the Cooum River and environs in Chennai, India. The Cooum is an extremely polluted urban stream. Its management is complicated by high rates of population growth, poverty, uncontrolled urban development, jurisdictional conflicts, institutional culture, flat topography, tidal action, blockage of the river mouth, and monsoon flooding. The situation is characterized by basic uncertainty about main processes and activities, and the nature of relationships among actors and elements in the system.SSM is an approach for dealing with messy or ill-structured problematic situations involving human activity. In this work SSM contributed techniques (such as "rich picture" and "CATWOE" tools) to description of the Cooum situation as a socioecological system and informed the approach itself at a theoretical level. Application of three general phases in SSM is discussed in the context of the Cooum River research: (1) problem definition and exploration of the problem situation, (2) development of conceptual models of relevant systems, and (3) the use of these to generate insight and stimulate debate about desirable and feasible change. Its use here gives weight to the statement by others that SSM would be a particularly appropriate methodology to operate the ecosystem approach. As well as informing efforts at management of the Cooum system, this work led the way to explore an adaptive ecosystem approach more broadly to management of the urban environment for human health in Chennai.

Social context of human immunodeficiency virus transmission in Africa: historical and cultural bases of east and central African sexual relations.

PubMed

Larson, A

1989-01-01

The literature relating to the social context of sexual relations in East and Central Africa has several implications for the heterosexual transmission of human immunodeficiency virus (HIV). Colonially created cities in the region still discriminate economically and socially against women. Rapid urbanization is occurring, but migrants maintain strong ties with rural areas. Traditional attitudes towards marriage and sexuality affect urban behavior in the extent of marital stability, the frequency of polygyny, and the emotional bond between spouses. Ethnic groups in Kampala and Nairobi exemplify the cultural foundations of two forms of sexual relations found in the region, one characterized by prostitution and the other by small circles of interchanging lovers. The first results in a more rapid spread of HIV through the urban population and outwards into rural areas. Each pattern exerts unique constraints on behavioral change and requires different prevention campaigns.

Helpful or harmful? The impact of strategic change on the performance of U.S. urban hospitals.

PubMed

Trinh, Hanh Q; O'Connor, Stephen J

2002-02-01

To contribute to the debate as to whether strategic change helps or harms organizations by empirically examining how strategic change influences performance change in urban hospitals. AHA Annual Survey (1994 and 1996), Health Care Financing Administration's Medicare Cost Reports (1994 and 1996) and Medicare HMO Files (1994), U.S. Bureau of the Census' County Business Patterns Files (1994), and Area Resources File (1994). This work employed a longitudinal approach using a panel design to study the effect of environmental and organizational characteristics on urban hospital strategic behavior and performance. A path analytic model was used to examine the simultaneous effects of environmental and organizational characteristics (1994) on strategic behavior (change in strategies to enhance HMO business and change in strategies to control costs 1994-96), as well as the effects of all of these variables on change in urban hospital performance (change in market share, change in operational efficiency, change in financial performance 1994-96). (1) Environmental context exerts a greater influence on urban hospitals' HMO business enhancement strategies, whereas organizational characteristics have more influence on cost-control strategies. (2) Between the two strategies, HMO business enhancement and cost control, strategic change to enhance business with HMOs is much more complex. (3) Strategic change observed across the 1994 to 1996 time period can be either helpful or harmful to urban hospitals. A strategic change that contributes positively to one type of performance can negatively impact the other. Although differences of opinion persist in the strategic change debate, results of this study indicate that strategic change can be helpful or harmful to urban hospitals, and its consequences are far more complex than previously thought. Strategic rationality has its own limitations and cannot always be relied on to yield expected results. Hospital strategic changes require coordination to achieve greater performance results.

Becoming urban science teachers by transforming middle-school classrooms: A study of the Urban Science Education Fellows Program

NASA Astrophysics Data System (ADS)

Furman, Melina Gabriela

The current scenario in American education shows a large achievement and opportunity gap in science between urban children in poverty and more privileged youth. Research has shown that one essential factor that accounts for this gap is the shortage of qualified science teachers in urban schools. Teaching science in a high poverty school presents unique challenges to beginner teachers. Limited resources and support and a significant cultural divide with their students are some of the common problems that cause many novice teachers to quit their jobs or to start enacting what has been described as "the pedagogy of poverty." In this study I looked at the case of the Urban Science Education Fellows Program. This program aimed to prepare preservice teachers (i.e. "fellows") to enact socially just science pedagogies in urban classrooms. I conducted qualitative case studies of three fellows. Fellows worked over one year with science teachers in middle-school classrooms in order to develop transformative action research studies. My analysis focused on how fellows coauthored hybrid spaces within these studies that challenged the typical ways science was taught and learned in their classrooms towards a vision of socially just teaching. By coauthoring these hybrid spaces, fellows developed grounded generativity, i.e. a capacity to create new teaching scenarios rooted in the pragmatic realities of an authentic classroom setting. Grounded generativity included building upon their pedagogical beliefs in order to improvise pedagogies with others, repositioning themselves and their students differently in the classroom and constructing symbols of possibility to guide their practice. I proposed authentic play as the mechanism that enabled fellows to coauthor hybrid spaces. Authentic play involved contexts of moderate risk and of distributed expertise and required fellows to be positioned at the intersection of the margins and the center of the classroom community of practice. In all, this study demonstrates that engaging in classroom reform can support preservice teachers in developing specialized tools to teach science in urban classrooms.

Xie, Qijiao; Wu, Yingjiao; Zhou, Zhixiang; Wang, Zhengxiang

2018-02-01

Satellite remote sensing technology provides informative data for detecting the land surface temperature (LST) distribution and urban heat island (UHI) effect remotely and regionally. In this study, two Landsat Thematic Mapper (TM) images acquired on September 26, 1987 and September 17, 2013 were used to derive LST and the normalized difference vegetation index (NDVI) values in Wuhan, China. The relationships between NDVI and LST were examined in different contexts, namely built-up area, farmland, grassland and forest. Results showed that negative correlations between the mean NDVI and LST were detected in all observed land covers, which meant that vegetation was efficient in decreasing surface temperatures and mitigating UHI effect. The cooling efficiency of vegetation on thermal environment varied with different contexts. As mean NDVI increased at each 0.1, the decreased LST values in built-up area, farmland, grassland and forest were 1.4 °C, 1.4 °C, 1.1 °C, 1.9 °C in 1987 and 1.4 °C, 1.7 °C, 1.3 °C, 1.8 °C in 2013, respectively. This finding encourages urban planners and greening designers to devote more efforts in protecting urban forests.

2016-07-01

Background and aim Current health-care delivery requires increasingly proactive and inter-professional work. Therefore, collecting patient information and knowledge management is of paramount importance. General practitioners (GPs) are well placed to lead these evolving models of care delivery. However, it is unclear how they are handling these changes. To gain an insight into this matter, the HIV epidemic was chosen as a test case. Data were collected and analysed from 13 semi-structured interviews with GPs, working in urban communities in Flanders. Findings GPs use various types of patient information to estimate patients' risk of HIV. The way in which sexual health information is collected and registered, depends on the type of information under discussion. General patient information and medical history data are often automatically collected and registered. Proactively collecting sexual health information is uncommon. Moreover, the registration of the latter is not obvious, mostly owing to insufficient space in the electronic medical record (EMR). GPs seem willing to systematically collect and register sexual health information, in particular about HIV-risk factors. They expressed a need for guidance together with practical adjustments of the EMR to adequately capture and share this information.

Mosquito control programs at seven urban sites in Kenya, Egypt, Israel, Costa Rica, and Trinidad are described and compared. Site-specific urban and disease characteristics, organizational diagrams, and strengths, weaknesses, obstacles and threats (SWOT) analysis tools are used to provide a descriptive assessment of each mosquito control program, and provide a comparison of the factors affecting mosquito abatement. The information for SWOT analysis is collected from surveys, focus-group discussions, and personal communication. SWOT analysis identified various issues affecting the efficiency and sustainability of mosquito control operations. The main outcome of our work was the description and comparison of mosquito control operations within the context of each study site's biological, social, political, management, and economic conditions. The issues identified in this study ranged from lack of inter-sector collaboration to operational issues of mosquito control efforts. A lack of sustainable funding for mosquito control was a common problem for most sites. Many unique problems were also identified, which included lack of mosquito surveillance, lack of law enforcement, and negative consequences of human behavior. Identifying common virtues and shortcomings of mosquito control operations is useful in identifying "best practices" for mosquito control operations, thus leading to better control of mosquito biting and mosquito-borne disease transmission.

Identifying common virtues and shortcomings of mosquito control operations is useful in identifying “best practices” for mosquito control operations, thus leading to better control of mosquito biting and mosquito-borne disease transmission.

The present work provides an overview of the most relevant results concerning a five years monitoring programme of wet and dry deposition (1995-1999) in the city of Bologna. The aim of this research is to get an overall picture of atmospheric pollutants deposition inventory in an urban territory and to allow an assessment of the vulnerability of the area by comparing actual fluxes of acidity and nutrient nitrogen with the respective "critical loads" associated to the territory, in the framework of the UNECE LRTAP (Long Range Transboundary Air Pollution Convention). This comparison, for the Bologna monitoring station, shows "exceedance classes" from 4 to 6 for acidity and from 1 to 5 for nutrient nitrogen, reflecting an urban-industrial context, though a trend in reducing occurs from 1995 to 1999. A water layer surface sampler (DAS-MTX sampler) was employed for "surrogate" dry deposition collection. The contribute of dry fraction to the total deposition fluxes appears to prevail on wet fraction for many pollutants (up to more than 90% for total calcium and alkalinity). A comparison with long term monitoring results from some stations in Italian territory, shows that the differences among chemical species deposition fluxes may be ascribed both to the long distance aerial transport of pollutants and to site characteristics.

Changing ecosystem service values following technological change.

Honey-Rosés, Jordi; Schneider, Daniel W; Brozović, Nicholas

Research on ecosystem services has focused mostly on natural areas or remote places, with less attention given to urban ecosystem services and their relationship with technological change. However, recent work by urban ecologists and urban designers has more closely examined and appreciated the opportunities associated with integrating natural and built infrastructures. Nevertheless, a perception remains in the literature on ecosystem services that technology may easily and irreversibly substitute for services previously obtained from ecosystems, especially when the superiority of the engineered system motivated replacement in the first place. We emphasize that the expected tradeoff between natural and manufactured capital is false. Rather, as argued in other contexts, the adoption of new technologies is complementary to ecosystem management. The complementarity of ecosystem services and technology is illustrated with a case study in Barcelona, Spain where the installation of sophisticated water treatment technology increased the value of the ecosystem services found there. Interestingly, the complementarity between natural and built infrastructures may remain even for the very ecosystems that are affected by the technological change. This finding suggests that we can expect the value of ecosystem services to co-evolve with new technologies. Technological innovation can generate new opportunities to harness value from ecosystems, and the engineered structures found in cities may generate more reliance on ecosystem processes, not less.

Urban Planning and Sustainable Development in The 21st Century, Conceptual and Management Issues

Azpeitia Santander, Arturo; Azkarate Garai-Olaun, Agustín

2016-10-01

Urban areas in historic cities resemble a living organism that evolves in parallel to social transformation processes, shaping the material substrate that expresses identity and collective memory. In the twenty-first century, exponential population growth, globalization and the information society have resulted in many of these socio-economic processes accelerating, with consequences that we are not yet able to discern in their entirety. In this context, cities need to adapt to the general dynamics of urban development by incorporating the environmental, economic and social aspects of the "sustainability paradigm". With good planning, urban heritage is a key sustainable resource that needs promoting as part of the existing territorial competitiveness in a scenario marked by an increase in rivalry between cities. This requires the development of a conceptual framework that, based on a global, holistic and integrative approach, covers equity and social justice, respect for human rights, the gender perspective, public health and environmental quality, among other aspects. In this sense, the purpose of this paper is to study the concept of landscape applied to urban planning in greater depth, paying special attention to the analysis of the notion of Historic Urban Landscapes from a critical point of view, since the economic pressures arising from the reality of today's globalized world pose a serious threat that hinders their custody and protection, complicating this new comprehensive approach: how to bring this new systemic and transversal concept to the current regulatory framework in order to achieve real legal protection and effective governance models in urban areas? What should be the acceptable limits to ensure that "managing this change" does not result in public spaces being at the service of the interests of financial capitalism? These, along with many other questions, make the work of the professionals in charge of urban conservation more challenging in their aim to establish a sustainable dialogue to clear the complex equation between historical city and development. With a view to try to answer these and other questions, this paper sets out need to design comprehensive urban policy and legislative frameworks coordinated, and sets out proposals regarding the development of acceptable change limitation methods and indicators, and the application of the concept of buffer zones to the conservation of urban heritage that can become the basis for urban management policies and models.

Low genetic variability, female-biased dispersal and high movement rates in an urban population of Eurasian badgers Meles meles.

1. Urban and rural populations of animals can differ in their behaviour, both in order to meet their ecological requirements and due to the constraints imposed by different environments. The study of urban populations can therefore offer useful insights into the behavioural flexibility of a species as a whole, as well as indicating how the species in question adapts to a specifically urban environment. 2. The genetic structure of a population can provide information about social structure and movement patterns that is difficult to obtain by other means. Using non-invasively collected hair samples, we estimated the population size of Eurasian badgers Meles meles in the city of Brighton, England, and calculated population-specific parameters of genetic variability and sex-specific rates of outbreeding and dispersal. 3. Population density was high in the context of badger densities reported throughout their range. This was due to a high density of social groups rather than large numbers of individuals per group. 4. The allelic richness of the population was low compared with other British populations. However, the rate of extra-group paternity and the relatively frequent (mainly temporary) intergroup movements suggest that, on a local scale, the population was outbred. Although members of both sexes visited other groups, there was a trend for more females to make intergroup movements. 5. The results reveal that urban badgers can achieve high densities and suggest that while some population parameters are similar between urban and rural populations, the frequency of intergroup movements is higher among urban badgers. In a wider context, these results demonstrate the ability of non-invasive genetic sampling to provide information about the population density, social structure and behaviour of urban wildlife.

The Relationships Between Depressive Symptoms, Functional Health Status, Physical Activity, and the Availability of Recreational Facilities: a Rural-Urban Comparison in Middle-Aged and Older Chinese Adults.

PubMed

Deng, Yazhuo; Paul, David R

2018-06-01

This study drew upon the ecological system theory to demonstrate rural-urban differences in the relationships between the availability of recreational facilities, physical activity (PA), functional health status, and depressive symptoms in middle-aged and older Chinese adults. Nationally representative data (n = 5949) from the Chinese Health and Retirement Longitudinal Study (CHARLS, 2011-2013) were examined using the multigroup structural equation modeling approach. The results suggest that higher availability of recreational facilities in the urban communities was associated with higher levels of leisure time physical activity (LTPA), better functional capacity, and less occurrence of depressive symptoms among urban participants. In contrast, LTPA engagement among rural participants was low and had negligible mitigating effects on functional decline and depressive symptoms. The findings also show that functional health status mediated the association between total PA and depressive symptoms in both rural and urban participants. However, high levels of total PA were directly associated with elevated depressive symptoms, suggesting that the context of PA and related socioeconomic factors might explain this association after the non-LTPA components were included. The findings highlight how complex patterns of intrapersonal, behavioral, and environmental correlates influence depressive symptoms in middle-aged and older Chinese adults. The context of PA should be considered when creating targeted strategies to prevent depressive symptoms. As an inactive lifestyle evolves with China's rapid urbanization, joint efforts from public health and urban planning should be made to promote LTPA and develop active living communities for achieving optimal health in later life.

Modelling the urban water cycle as an integrated part of the city: a review.

PubMed

Urich, Christian; Rauch, Wolfgang

2014-01-01

In contrast to common perceptions, the urban water infrastructure system is a complex and dynamic system that is constantly evolving and adapting to changes in the urban environment, to sustain existing services and provide additional ones. Instead of simplifying urban water infrastructure to a static system that is decoupled from its urban context, new management strategies use the complexity of the system to their advantage by integrating centralised with decentralised solutions and explicitly embedding water systems into their urban form. However, to understand and test possible adaptation strategies, urban water modelling tools are required to support exploration of their effectiveness as the human-technology-environment system coevolves under different future scenarios. The urban water modelling community has taken first steps to developing these new modelling tools. This paper critically reviews the historical development of urban water modelling tools and provides a summary of the current state of integrated modelling approaches. It reflects on the challenges that arise through the current practice of coupling urban water management tools with urban development models and discusses a potential pathway towards a new generation of modelling tools.

Urban green spaces provide an array of benefits, or ecosystem services, that support our physical, psychological, and social health. In many cases, however, these benefits are not equitably distributed across diverse urban populations. In this paper, we explore relationships between cultural ecosystem services provided by urban green space and the social determinants of health outlined in the United States Healthy People 2020 initiative. Specifically, we: (1) explore connections between cultural ecosystem services and social determinants of health; (2) examine cultural ecosystem services as nature-based health amenities to promote social equity; and (3) recommend areas for future research examining links between urban green space and public health within the context of environmental justice.

Step-Up: Promoting Youth Mental Health and Development in Inner-City High Schools

PubMed Central

Pardo, Gisselle; Conover, Kelly; Gopalan, Geetha; McKay, Mary

2011-01-01

African American and Latino youth who reside in inner-city communities are at heightened risk for compromised mental health, as their neighborhoods are too often associated with serious stressors, including elevated rates of poverty, substance abuse, community violence, as well as scarce youth-supportive resources, and mental health care options. Many aspects of disadvantaged urban contexts have the potential to thwart successful youth development. Adolescents with elevated mental health needs may experience impaired judgment, poor problem-solving skills, and conflictual interpersonal relationships, resulting in unsafe sexual behavior and drug use. However, mental health services are frequently avoided by urban adolescents who could gain substantial benefit from care. Thus, the development of culturally sensitive, contextually relevant and effective services for urban, low-income African American and Latino adolescents is critical. Given the complexity of the mental health and social needs of urban youth, novel approaches to service delivery may need to consider individual (i.e., motivation to succeed in the future), family (i.e., adult support within and outside of the family), and community-level (i.e., work and school opportunities) clinical components. Step-Up, a high school-based mental health service delivery model has been developed to bolster key family, youth and school processes related to youth mental health and positive youth development. Step-Up (1) intervenes with urban minority adolescents across inner-city ecological domains; (2) addresses multiple levels (school, family and community) in order to target youth mental health difficulties; and (3) provides opportunities for increasing youth social problem-solving and life skills. Further, Step-Up integrates existing theory-driven, evidence-based interventions. This article describes Step-Up clinical goals, theoretical influences, as well as components and key features, and presents preliminary data on youth engagement for two cohorts of students.

Urbanism and the division of labour in the Roman Empire.

PubMed

Hanson, J W; Ortman, S G; Lobo, J

2017-11-01

One of the hallmarks of human agglomeration is an increase in the division of labour, but the exact nature of this relationship has been debated among anthropologists, sociologists, economists, and historians and archaeologists. Over the last decade, researchers investigating contemporary urban systems have suggested a novel explanation for the links between the numbers of inhabitants in settlements and many of their most important characteristics, which is grounded in a view of settlements as social networks embedded in built environments. One of the remarkable aspects of this approach is that it is not based on the specific conditions of the modern world (such as capitalism or industrialization), which raises the issue of whether the relationships observed in contemporary urban systems can also be detected in pre-modern urban or even non-urban systems. Here, we present a general model for the relationship between the population and functional diversity of settlements, where the latter is viewed as an indicator of the division of labour. We then explore the applicability of this model to pre-modern contexts, focusing on cities in the Roman Empire, using estimates of their numbers of inhabitants, numbers of documented professional associations, and numbers of recorded inscriptions to develop an index of functional diversity. Our results are consistent with theoretical expectations, adding further support to the view that urban systems in both contemporary and pre-modern contexts reflect a common set of generative processes. © 2017 The Authors.

Urban pollution remains a major sanitary and economic concern. In France, particulate pollution is known to cause 48,000 premature deaths every year (Santé Publique France, 2016), while the economic cost of air pollution reaches almost 25 billion euros per year (CGDD, 2012). In the Greater Paris, despite strengthened emission standards, restricted traffic areas, car-sharing and incentives for electric vehicle use, road transport plays a substantial role in the exposure of inhabitants to high levels of pollutants. In this context, urban planning could possibly constitute an innovative strategy to reduce emissions from road traffic, through its actions on transport demand, travel distances, modal shift (public transportation, cycling, walking...) or even proximity to emitters. We have developed a multi-scalar modeling of urban pollution by coupling an urban economic growth model NEDUM (CIRED), a model for urban mobility (LISA), a traffic emission model (LISA) and the CHIMERE Chemistry-Transport model (CTM) for air quality simulation (LISA). The innovative aspect of this modeling system is to integrate into a classic CTM the mechanisms underlying the dynamics of an urban system. This way, we establish a quantitative and comprehensive link between a given urban scenario, the associated public and individual transport matrix, and local air quality. We then make it possible to highlight the levers of energy consumption reductions inside compact or sprawled cities. We have been working on the Ile de France region (centered on the Paris agglomeration) which relies on a broad urban structure of megacity, a high density of housing and an expanding urban peripheral zone, clearly raising the issue of transport demand, mobility and traffic congestion. Two scenarios, considering opposite urban development policies from the 1960s to 2010, have been simulated over the whole modelling chain. The first one promotes a dense and compact city while the second favors city spread, though restricted by a green belt. In our results, we compare the local air quality simulated in these scenarios with our reference situation (the current 2010 situation). The spreading or densification of the city contribute a little to the air quality and therefore a reflection on a real mix of the urban canvas is probably an influencing factor for the reduction of the motorized mobility. We should also consider more advanced scenarios (in the course of production) for the reduction of individual transport like encouraging car-pooling, which has a maximum daily trip reduction potential of 16% in urban areas (CGDD, 2014).

Urban sprawl is a worldwide phenomenon happening particularly in rapidly developing regions. A study on the spatiotemporal characteristics of urban sprawl and urban pattern is useful for the sustainable management of land management and urban land planning. The present research explores the spatiotemporal dynamics of urban sprawl in the context of a rapid urbanization process in a booming economic region of southern China from 1979 to 2005. Three urban sprawl types are distinguished by analyzing overlaid urban area maps of two adjacent study years which originated from the interpretation of remote sensed images and vector land use maps. Landscape metrics are used to analyze the spatiotemporal pattern of urban sprawl for each study period. Study results show that urban areas have expanded dramatically, and the spatiotemporal landscape pattern configured by the three sprawl types changed obviously. The different sprawl type patterns in five study periods have transformed significantly, with their proportions altered both in terms of quantity and of location. The present research proves that urban sprawl quantification and pattern analysis can provide a clear perspective of the urbanization process during a long time period. Particularly, the present study on urban sprawl and sprawl patterns can be used by land use and urban planners.

Aims As part of a larger study on prescription drug misuse among young adults active in urban nightlife scenes, we examined participants’ motivations for misuse. Prescription painkillers, stimulants and sedatives were the primary substances of interest. Methods Participants were recruited from nightlife venues in New York using time-space sampling. Subjects completed a mixed-methods assessment at project research offices. The data presented here are from a subsample of 70 qualitative interviews conducted during the baseline assessment. Findings We identified experimentation and a “work hard, play hard” ethos as key motivations for misusing prescription drugs and argue that these motivations are specific, though not necessarily unique, to the participants’ social location as young adults. These findings highlight the role of life stage and social context in the misuse of prescription drugs. Conclusion Future studies of prescription drug misuse should pay attention to the larger social contexts in which users are embedded and, therefore, make decisions about how and why to misuse. Moving beyond the very broad concepts of “recreation” and “self-medication” presently established in the research, policies targeting young adults may want to tailor intervention efforts based on motivations.

Communities, Classrooms, and Peers: Examining How Local Contexts Shape Female Students' STEM Intentions

NASA Astrophysics Data System (ADS)

Riegle-Crumb, Catherine

2017-01-01

Despite being the focus of decades of research as well as interventions, gender inequality in representation in many STEM fields, including physics, engineering, and computer science remains. Recent research indicates that high school is a particularly important time point to investigate regarding the roots of inequality, as this is when many young women decide that they are not interested in pursuing degrees in these STEM fields. This presentation will focus on the role of local contexts, including communities, classrooms, and peers, in contributing to such decisions. Specifically, sociological theories suggest that role models and peers within young people's immediate environment can send both implicit and explicit messages that contradict larger social stereotypes, and promote perceptions and experiences of inclusion. Alternatively, adults and peers can endorse and behave in a manner consistent with stereotypes, leading to overtly exclusionary messages and actions. Utilizing data from a large urban district in the Southwest, as well as a national sample of high school students, this presentation will examine how such factors within local contexts can work in both positive and negative ways to shape girls' interests and expectations in STEM fields.

Exploring Social Justice in Mixed/Divided Cities: From Local to Global Learning.

PubMed

Shdaimah, Corey; Lipscomb, Jane; Strier, Roni; Postan-Aizik, Dassi; Leviton, Susan; Olsen, Jody

University of Haifa and the University of Maryland, Baltimore faculty developed a parallel binational, interprofessional American-Israeli course which explores social justice in the context of increasing urban, local, and global inequities. This article describes the course's innovative approach to critically examine how social justice is framed in mixed/divided cities from different professional perspectives (social work, health, law). Participatory methods such as photo-voice, experiential learning, and theatre of the oppressed provide students with a shared language and multiple media to express and problematize their own and others' understanding of social (in)justice and to imagine social change. Much learning about "self" takes place in an immersion experience with "others." Crucial conversations about "the other" and social justice can occur more easily within the intercultural context. In these conversations, students and faculty experience culture as diverse, complex, and personal. Students and faculty alike found the course personally and professionally transformative. Examination of social justice in Haifa and Baltimore strengthened our appreciation for the importance of context and the value of global learning to provide insights on local challenges and opportunities.

This study describes women's perceptions of the supports and barriers to maintaining a healthy weight among currently healthy weight women from urban and rural socio-economically disadvantaged areas. Using focus groups and interviews, we asked women about their experiences of maintaining a healthy weight. Overwhelmingly, women described their healthy weight practices in terms of concepts related to work and management. The theme of 'managing health' comprised issues of managing multiple responsibilities, time, and emotions associated with healthy practices. Rural women faced particular difficulties in accessing supports at a practical level (for example, lack of childcare) and due to the gendered roles they enacted in caring for others. Family background (in particular, mothers' attitudes to food and weight) also appeared to influence perceptions about healthy weight maintenance. In the context of global increases in the prevalence of obesity, the value of initiatives aimed at supporting healthy weight women to maintain their weight should not be under-estimated. Such initiatives need to work within the social and personal constraints that women face in maintaining good health.

Informed by Kohn and Schooler's (1969) occupational socialization framework, this study examined linkages between racial/ethnic minority mothers' perceptions of racial/ethnic discrimination in the workplace and adolescents' accounts of racial/ethnic socialization in the home. Data were collected from 100 mother-early adolescent dyads who participated in a longitudinal study of urban adolescents' development in the Northeastern United States, including African American, Latino, and Chinese families. Mothers and adolescents completed surveys separately. We found that when mothers reported more frequent institutional discrimination at work, adolescents reported more frequent preparation for bias messages at home, across racial/ethnic groups. Mothers' experiences of interpersonal prejudice at work were associated with more frequent cultural socialization messages among African American and Latino families. Chinese youth reported fewer cultural socialization messages when mothers perceived more frequent interpersonal prejudice at work. Findings are discussed in the context of minority groups' distinct social histories and economic status in the United States. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

Approach of ICT Application to Governance in Urban Planning

NASA Astrophysics Data System (ADS)

Virtudes, Ana; Sá, João

2017-10-01

This article discusses the use of information and communication technologies (ICT) at the local level of governance in the field of urban planning. It is based on a literature review, in order to define a set of considerations about their use in the urban context and the challenges ahead on this domain. As a starting point, there is the need of rethinking the local governance through the use of ICT related to cities, focused on the modernization of the processes associated with urban planning. Nowadays, in several societies the paradigm about cities if shifting, from an expansionist way of acting towards a regeneration and rehabilitation approach. In the case of Portugal, the local authorities; the municipalities; are the main responsible for the coordination, and integration of policies with territorial impacts. However, these policies are generally onerous and inefficient, triggering communication and information failures in between local administration and citizens. In this sense, governance should support the decision-making process related to cities’ policies, engaging citizens and socio-economic agents. As the main result in this scenario, the use of ICT demonstrates the ability to play an important role in urban planning, by contributing as a simplifying tool, regarding the information and knowledge sharing, gathering local authorities, citizens and socio-economic agents. On the one hand, they promote the reduction of inefficiencies associated to the urban planning process. On the other hand, they boost the development of networks, and consequently the social and territorial cohesion. In summary, the use of ICT infrastructures works as a glue allowing the integration of several intelligence elements of the city, and operating as their base platform. Finally, the literature has revealed that the use of ICT in urban planning should be seen as a means to a wider social goal, and not as an end by itself. With the use of ICT, urban planning authorities are more likely to be aware of the city features in their multiple aspects, being able to define and monitoring the public policies, suitable to each situation, reinforcing the democracy and transparency of local governance.

This study is aimed at analyzing urban change within Istanbul and assessing the city's future growth potential using appropriate approach modeling for the year 2040. Urban growth is a major driving force of land-use change, and spatial and temporal components of urbanization can be identified through accurate spatial modeling. In this context, widely used urban modeling approaches, such as the Markov chain and logistic regression based on cellular automata (CA), were used to simulate urban growth within Istanbul. The distance from each pixel to the urban and road classes, elevation, and slope, together with municipality and land use maps (as an excluded layer), were identified as factors. Calibration data were obtained from remotely sensed data recorded in 1972, 1986, and 2013. Validation was performed by overlaying the simulated and actual 2013 urban maps, and a kappa index of agreement was derived. The results indicate that urban expansion will influence mainly forest areas during the time period of 2013-2040. The urban expansion was predicted as 429 and 327 km(2) with the Markov chain and logistic regression models, respectively.

This study tested the feasibility of a combined microcredit and life-skills HIV prevention intervention among 50 adolescent female orphans in urban/peri-urban Zimbabwe. Quantitative and qualitative data were collected on intervention delivery, HIV knowledge and behavior, and economic indicators. The study also tested for HIV, HSV-2, and pregnancy. At 6 months, results indicated improvements in knowledge and relationship power. Because of the economic context and lack of adequate support, however, loan repayment and business success was poor. The results suggest that microcredit is not the best livelihood option to reduce risk among adolescent girls in this context.

A real-time control framework for urban water reservoirs operation

NASA Astrophysics Data System (ADS)

Galelli, S.; Goedbloed, A.; Schwanenberg, D.

2012-04-01

Drinking water demand in urban areas is growing parallel to the worldwide urban population, and it is acquiring an increasing part of the total water consumption. Since the delivery of sufficient water volumes in urban areas represents a difficult logistic and economical problem, different metropolitan areas are evaluating the opportunity of constructing relatively small reservoirs within urban areas. Singapore, for example, is developing the so-called 'Four National Taps Strategies', which detects the maximization of water yields from local, urban catchments as one of the most important water sources. However, the peculiar location of these reservoirs can provide a certain advantage from the logistical point of view, but it can pose serious difficulties in their daily management. Urban catchments are indeed characterized by large impervious areas: this results in a change of the hydrological cycle, with decreased infiltration and groundwater recharge, and increased patterns of surface and river discharges, with higher peak flows, volumes and concentration time. Moreover, the high concentrations of nutrients and sediments characterizing urban discharges can cause further water quality problems. In this critical hydrological context, the effective operation of urban water reservoirs must rely on real-time control techniques, which can exploit hydro-meteorological information available in real-time from hydrological and nowcasting models. This work proposes a novel framework for the real-time control of combined water quality and quantity objectives in urban reservoirs. The core of this framework is a non-linear Model Predictive Control (MPC) scheme, which employs the current state of the system, the future discharges furnished by a predictive model and a further model describing the internal dynamics of the controlled sub-system to determine an optimal control sequence over a finite prediction horizon. The main advantage of this scheme stands in its reduced computational requests and the capability of exploiting real-time hydro-meteorological information, which are crucial for an effective operation of these fast-varying hydrological systems. The framework is here demonstrated on the operation of Marina Reservoir (Singapore), whose recent construction in late 2008 increased the effective catchment area to about 50% of the total available. Its operation, which accounts for drinking water supply, flash floods control and water quality standards, is here designed by combining the MPC scheme with the process-based hydrological model SOBEK. Extensive simulation experiments show the validity of the proposed framework.

The rising morbidity and mortality due to non-communicable diseases can be partly attributed to the urbanized lifestyle leading to unhealthy dietary practices and increasing physical levels of inactivity. The demographic and nutrition transition in India has also contributed to the emerging epidemic of non-communicable diseases in this country. In this context, there is limited information in India on dietary patterns, levels of physical activity and obesity. The aim of the present study was thus to assess the urban rural differences in dietary habits, physical activity and obesity in India. A household survey was done in the state of Punjab, India in a multistage stratified sample of 5127 individuals using the WHO STEPS questionnaire. No rural urban difference was found in dietary practices and prevalence of overweight and obesity except the fact that a significantly higher proportion of respondents belonging to rural area (15.6 %) always/often add salt before/when eating as compared to urban area (9.1 %). Overall 95.8 % (94.6-97.0) of participants took less than 5 servings of fruits and/or vegetables on average per day. No significant urban rural difference was noted in both sexes in all three domains of physical activity such as work, transport and recreation. However, rural females (19.1 %) were found to be engaged in vigorous activity more than the urban females (6.3 %). Males reported high levels of physical activity in both the settings. Absence of recreational activity was reported by more than 95 % of the subjects. Higher prevalence of obesity (asian cut offs used) was seen among urban females (34.3 %) as compared to their rural counterparts (23.2 %). Abdominal obesity was found to be significantly higher among females in both the settings compared to males (p < 0.001). Poor dietary practices and physical inactivity seems to fuel the non-communicable disease epidemic in India. Non communicable disease control strategy need to address these issues with a gender equity lens. Rapid urbanization of rural India might be responsible for the absence of a significant urban rural difference.

Impact of Climate Conditions on Occupational Health and Related Economic Losses: A New Feature of Global and Urban Health in the Context of Climate Change.

PubMed

Kjellstrom, Tord

2016-03-01

One feature of climate change is the increasing heat exposure in many workplaces where efficient cooling systems cannot be applied. Excessive heat exposure is a particular problem for working people because of the internal heat production when muscle work is carried out. The physiological basis for severe heat stroke, other clinical effects, and heat exhaustion is well known. One feature of this health effect of excessive workplace heat exposure is reduced work capacity, and new research has started to quantify this effect in the context of climate change. Current climate conditions in tropical and subtropical parts of the world are already so hot during the hot seasons that occupational health effects occur and work capacity for many working people is affected. The Hothaps-Soft database and software andClimateCHIP.orgwebsite make it possible to rapidly produce estimates of local heat conditions and trends. The results can be mapped to depict the spatial distribution of workplace heat stress. In South-East Asia as much as 15% to 20% of annual work hours may already be lost in heat-exposed jobs, and this may double by 2050 as global climate change progresses. By combining heat exposure data and estimates of the economic consequences, the vulnerability of many low- and middle-income countries is evident. The annual cost of reduced labor productivity at country level already in 2030 can be several percent of GDP, which means billions of US dollars even for medium-size countries. The results provide new arguments for effective climate change adaptation and mitigation policies and preventive actions in all countries. © 2015 APJPH.
