BackgroundIndividuals with early phase cognitive impairment are frequently affected by existential distress, social avoidance and associated health issues. The demand for efficient psychological support is crucial from both an individual and a societal perspective. We have developed a novel psychological intervention manual for providing a non-medical path to enhanced psychological health in the cognitively impaired population. The current article provides specific information on the randomized controlled trial -design and methods. The main hypothesis is that participants receiving PIPCI will increase (...) their psychological flexibility compared to participants in the active control group and the waiting list control group. The secondary hypotheses are that participants receiving PIPCI will improve psychological health compared to participants in the active control group and the waiting list control group.Materials and MethodsThis three-arm RCT will recruit participants from the cognitive centers at Karolinska University Hospital in Stockholm and randomize approximately 120 individuals in the early phase of cognitive impairment to either an experimental group, an active control group or a waiting list control group. Intervention outcome will be evaluated with self-report questionnaires on physical and psychological aspects of health, cognitive assessment, biological markers and health care costs. Assessments will be performed at pre- and post-intervention, as well as at a 6-month follow-up.DiscussionThe development of a potentially feasible and effective psychological intervention tailored for early phase cognitive impairment has the potential to advance the non-pharmacological intervention field. This is especially important given the extensive burden for many affected individuals and their families and the current lack of effective treatments. If the psychological intervention discussed here shows feasibility and efficacy, there is potential for far-reaching healthcare implications for patients with early cognitive impairment at risk of developing dementia.Clinical Trial RegistrationClinicalTrials.gov: NCT04356924.

Analysis and comparison of genetic screening programs shows that the extent of development of programs varies widely across Europe. Regional variations are due not only to genetic disease patterns but also reflect the novelty of genetic services. In most countries, the focus for genetic screening programs has been pregnant women and newborn children. Newborn children are screened only for disorders which are treatable. Prenatal screening when provided is for conditions for which termination may be offered. The only population screening (...) programs for adults are those for thalassaemia carrier status in Cyprus, Greece and Italy. Social responses to genetic screening range from acceptance to hostility. There is a fundamental tension between individual and communi ty in the debates in various European countries about implementation of screening programs. Opposition to genetic screening is frequently expressed in terms of arguments about "eugenics" with insufficient regard to the meaning of the term and its implications. Only a few countries have introduced explicit legislation on genetic screening. Legislation to address discrimination may provide more safeguards than legislation protecting genetic information itself. (shrink)

ABSTRACT In a series of experiments at the National Institute of Mental Health, the animal ecologist John B. Calhoun offered rats everything they needed, except space. The resulting population explosion was followed by a series of “social pathologies”—violence, sexual deviance, and withdrawal. This essay examines the influence of Calhoun's experiments among psychologists and sociologists concerned with the effects of the built environment on health and behavior. Some saw evidence of the danger of the crowd in Calhoun's “rat cities” and (...) fastened on a method of analysis that could be transferred to the study of urban man. Others, however, cautioned against drawing analogies between rodents and humans. The ensuing dispute saw social scientists involved in a careful negotiation over the structure and meaning of Calhoun's experimental systems and, with it, over the significance of the crowd in the laboratory, institution, and city.

The relationship between urban expansion and population density changes is complex and plays a fundamental role in urban sustainable development research. This relationship has been studied in multiple large cities. However, there is no report of the relationship of the two factors mentioned above in urban agglomeration in a particular region of China. Ten cities located in the central-southern region of Liaoning province are selected as research samples in this study. The spatial growth rate and (...) class='Hi'>urban compactness index of the sample cities were calculated using the land use and population data of these cities in three time phases: 1995, 2005, and 2015. Then, the geographical growth features, the population density changes, and the link between these two in the sample cities were investigated at these three periods. Our results revealed that the studied cities of central-southern Liaoning province expanded at the three time phases under the driver of positive population density growth, but the effects of urban population change on urbanization growth modes across time were uneven across different periods. Our study showed a trend that active transition of different urbanization growth modes was associated with decreased population density. (shrink)

Rapid Ethical Assessment is an approach used to design context tailored consent process for voluntary participation of participants in research including human subjects. There is, however, limited evidence on the design of ethical assessment in studies targeting cancer patients in Ethiopia. REA was conducted to explore factors that influence the informed consent process among female cancer patients recruited for longitudinal research from Addis Ababa Population-based Cancer Registry. Qualitative study employing rapid ethnographic approach was conducted from May–July, 2017, at the (...) Tikur Anbessa Specialized Referral Hospital. In-depth and key informants’ interviews were conducted among purposively selected 16 participants. Regular de-briefings among the study team helped to identify emerging themes and ensure saturation. Interviews and debriefings were tape recorded in Amharic, and transcribed and translated to English. Coding of the transcripts was facilitated by use of NVivo software. Thematic analysis was employed to respond to the initial questions and interpret findings. Perceived barriers to voluntary study participation included lack of reporting back study results of previous studies, the decision making status of women, hopelessness or fatigue in the patients, shyness of the women, data collectors approach to the patient, and patient’s time constraints. Most of the patients preferred oral over written consent and face-to-face interview over telephone interview. Provision of detail information about the study, using short and understandable tool, competent, compassionate and respectful enumerators of the same gender were suggested to assure participation. Due to the perceived severity, the use of the term “cancer” was associated with fear and anxiety. Alternatively, uses of phrases like “breast or cervical illness/disease” were suggested during patient interviews. Voluntary participation is not straight forward but affected by different factors. Using competent, compassionate and respectful enumerators, short and precise questioning tools to limit the time of the interview could improve voluntary participation. Moreover, careful consideration of the patients and families concept of the disease such as wording and information has to be taken into account. This assessment helped in improving the consent process of the ongoing project on breast and cervical cancer patients. (shrink)

Section 1 of this article presents a mathematical analysis of the longterm global urbanization dynamics and demonstrates that it could be described as a series of phase transitions between attraction basins. This makes it possible to suggest new approaches to the analysis of global social macroevolution. Section 2 presents a threestage model of the macroevolution of the World System statehood (early – developed – mature state) that, we believe, describes the main features of political macroevolution better than the twostage model (...) proposed by Claessen and Skalník (early – mature state). This model has been used as a basis for the analysis of changes in the development of political structures from the prestate polities and the most primitive early states (and their analogues) till the modern supercomplex states. In this section we also analyze the relationship between the growth of the territory controlled by the World System states and the growth of the statehood complexity. Finally, Section 3 attempts at the detection of the correlation between the global evolution of political structures and global urbanization processes. This study confirms the presence of a system of attraction basins and phase transitions within the World System macroevolutionary development field, as well as the presence of mathematically interpretable correlations and interrelations between the analyzed global processes – political, urbanizing, demographic, technological, and sociostructural.

SummaryAggarwal Baniyas were found to have a high prevalence of high blood pressure. Genetic and environmental influences may be implicated for this risk factor of cardiovascular disease. The aim of this study was to investigate the potential for common genetic and environmental influences on blood pressure measures ). The population-based sample was comprised of 309 Aggarwal Baniya families, including 1214 individuals from New Delhi, India. The prevalence of obesity in this community was found to be high. Correlation and heritability (...) were estimated. Most sibling–sibling correlations were larger than the parent–offspring correlations, and all parent–offspring and sibling–sibling correlations were larger than the corresponding spouse correlation. The maximum heritability was estimated as 44.6% for SBP and 62.8% for DBP. The lack of a significant spouse correlation is consistent with little or no influence of the common familial environment. However, the high heritability estimate for both SBP and DBPs reinforces the importance of the non-shared environmental effect. (shrink)

Much of the developing world, including Kenya, is rapidly urbanizing. Rising food and fuel prices in recent years have put the food security of the urban poor in a precarious position. In cities worldwide, urban agriculture helps some poor people gain access to food, but urban agriculture is less common in densely populated slums that lack space. In the Kibera slums of Nairobi, Kenya, households have recently begun a new form of urban agriculture called sack gardening (...) in which vegetables such as kale and Swiss chard are planted into large sacks filled with topsoil. This paper examines relationships among sack gardening, social capital, and food security in Kibera. We used a mixed methods approach, combining qualitative interviews with a household survey, as well as focus group discussions with both farmers and non-farmers. We present evidence that sack gardening increases social capital, especially for those households that undertake sack gardening in groups. We also find that sack gardening in the Kibera slums has a positive impact on household food security by improving household dietary diversity and by reducing the need to resort to painful coping mechanisms that are used during food shortages.

Grounded in a postcolonial, liberationist urban vision, this article lamented the theological and political paralysis of urban denialism that fails African cities and African urban populations. Considering different possible urban trajectories towards 2063 – ranging from floundering to flourishing, implosion to explosion, and apocalyptic disaster to complete rebirth – it then proposed theologies of African urban citizenship, as response. It sought to articulate a vision of citizen-driven African cities, remaking cities ‘from below’, through interconnected and (...) intersectional urban movements. It considered urban citizenship not as the decent and orderly conduct of subjects of the nation-state but as the disruptive and transformative presence and participation of citizens of God’s new city, breaking into cities across the African continent. While it bemoaned the absence of ‘Africa’s urban revolution’ from mainstream theologies and politics practised in the African context, and the insufficient attention paid to it even by the Africa 2063 manifesto, it dared to evoke hope, in spite of evidence to the contrary. This should be viewed as a conceptual contribution, fusing literature study with deep urban immersion. Contribution: Grounded in a postcolonial, liberationist urban vision, this article lamented the theological and political paralysis of urban denialism that fails African cities and African urban populations, contemplating theologies of African urban citizenship instead.

Population aging has brought great challenges to many regions throughout the world. Enhancing the sense of participation, access, and well-being of older adults is the goal of China’s aging development. This study, taking urban–rural difference as the entry point, examined the difference in subjective well-being between urban and rural older learners. A total of 2,007 older adults learners aged over 50 years were recruited in Zhejiang, Anhui, and Shandong Provinces in China, including 773 rural older adults and (...) 1,234 urban older adults. This study found that there was a significant positive correlation between senior learning and the subjective well-being of urban and rural older adult learners. Furthermore, there was a significant difference between the subjective well-being of urban and rural older adult learners’ and there was also an urban–rural difference between the effects of older adult learning on the subjective well-being. Based on the above findings, this study reveals the mechanism of the impact of older adult learning on subjective well-being of urban and rural older adults and gives relevant suggestions for improving the subjective well-being of urban and rural older learners.

IntroductionThis study aimed to explore the mental wellbeing profiles and their related factors among urban young adults in Vietnam.MethodsA cross-sectional study was conducted in Hanoi, which is the capital of Vietnam. There were 356 Vietnamese who completed the Mental Health Inventory-5 questionnaire. The Latent Profile Analysis was used to identify the subgroups of mental wellbeing through five items of the MHI-5 scale as the continuous variable. Multinomial logistic regression was used to determine factors related to subgroups.ResultsThree classes represented three (...) levels of MHI-5 score, which included “Poor mental health,” “Fair mental health,” and “Good mental health,” were, respectively, 14.3, 46.6, and 39.0%. Compared to a low household economy, participants with an average household economy had 2.11 and 4.79 times higher odds of being in a good mental health class relative to fair and poor mental health classes. Respondents with more than two acute symptoms had 3.85 times higher odds of being in a good mental health class relative to a poor mental health class, as compared to those without acute symptoms. Regarding the measurement of the Perceived Social Support Scale, people having support from their family had 1.80 and 2.23 times higher odds of being in classes of fair and good mental health relative to the poor mental health class; and participants having friend support also had 1.87 times higher odds of being in a good mental health class compared with the fair mental health class, as the MSPSS score increased by 1 unit. People with Rosenberg’s self-esteem scale increased by 1 score, those who had 1.17, 1.26, and 1.47 times higher odds of being in a good compared to fair mental health class, fair compared to poor mental health class, and good compared to poor mental health class, respectively.ConclusionOur findings were given to promote a new classification method for mental health screening among the general population. The current findings could be used as evidence to develop policies and plans that focus on encouraging early screening for mental health problems among the general young population in the future.

Diogenes, Ahead of Print. Western intellectual sources have dominated the social sciences to an extent that most definitions originate from a Eurocentric meaning system; words like urban, wild, nature, and culture being no exception.

It demonstrates that the meaning of a phrase, ‘being urban’, can only be understood in its historical, social/cultural, (...) and political context; that the notion of a civil society, and meaning of terms such as public and private may be contextualized in varying moral universes and value systems to mean quite different things in different contexts. Overall the paper seeks to illuminate the futility of monolithic and reductionist constructs and value of situational and ethnographically constructed meanings of social and cultural phenomena. It demonstrates that even dichotomies like urban/non-urban are fuzzy and fluid, given the actual situation of real cities and their population; that a city is not defined by structure alone but by the people who live in it.

Increasingly, we live in an environment of our own making: a ‘world as design’ over the natural world. For more than half of the global population, this environment is also thoroughly urban. But what does a global urban condition mean for the human condition? How does the design of the city and the urban process, in response to the issues and challenges of the Anthropocene, produce new ethical categories, shape new moral identities and relations, and bring (...) about consequences that are also morally significant? In other words, how does the urban shape the ethical—and in what ways? Conversely, how can ethics reveal relations and realities of the urban that often go unnoticed? This book marks the first systematic study of the city through the ethical perspective in the context of the Anthropocene. Six emergent urban conditions are examined, namely, precarity, propinquity, conflict, serendipity, fear and the urban commons. (shrink)

Poverty creates many problems. Out of which one major problem is an increase in migration rate. In Pakistan, the rate of inter province and rural urban migration has increased in the last few years resulting in an expansion in urban population. The objective of this study was to explore the experience of women who have migrated from rural to urban areas with their families and are living in urban slums. Moreover, the study aims to explore (...) the reasons of migration from rural to urban areas, the change occurred in their living conditions and their level of satisfaction. Total 100 women from selected katchi abadis of Karachi and were in-depth interviewed through questionnaire method. To have an in depth analysis of the situation, both open and closed ended questions were included. Results show that most of these women have migrated with their families due to poverty. The need is to take decisions that promote equity and social justice. The distribution of resources and development planning need to focus on the need of urban and rural areas on equal bases because just moving towards metropolitan city does not change their living rather it is deteriorating the situation.

Urban networks have been widely examined using infrastructure connection and firm connection data. In particular, urban networks constructed based on firm connection data have been used to depict the circulation of capital, information, personnel, and products between cities. Existing studies on firm connection networks rely on either inter- or intrafirm relationships. However, there exist various important extra-firm relationships, such as those between firms and governments, research institutions, and nonprofit organizations. This study innovatively incorporates the extra-firm relationships between governments (...) and firms into urban network construction to provide new insights into the field of urban network research. Using Northeast China as a case study, we construct government procurement activity connection networks for both central projects and local projects at the regional and national scales. Social network analysis and regression analysis are used to analyze the network characteristics and factors associated with the network structure. The results show that three provincial capitals hold dominant positions across all the networks. While these capitals serve as GPA suppliers in the region, they are mainly GPA consumers nationally. The factors of spatial proximity, economic development, population, and provincial boundaries were found to be significantly associated with GPA connections. Our study provides important insights into the role of cities in firm-government supply-demand networks. This research can be used to help formulate effective strategies to improve a city’s competitiveness and cities’ cooperation in the GPA supply-demand network. (shrink)

Nowadays, around half of the global population lives in urban areas. This rate is expected to increase up to two-thirds by the year 2050. Most studies analyze urban dynamics in wide geographic ranges, focusing mainly on cities. According to them, the global population is spatially distributed in two extremes: large urban agglomerations and rural deserts. However, this remark is excessively general and imprecise. For this reason, it remains essential to analyze these dynamics at other spatial (...) scales. A close-up look in thinly populated regions shows how urban dynamics are also noticeable. In this paper, we analyze spatiotemporal patterns of population distribution in a predominantly rural area by applying a local-scale approach. These patterns are represented by using spatial networks with nodes representing the human settlements and links showing hierarchies between nodes. This case study is conducted in a small municipality located in northwestern Spain. It is a predominantly rural area with a very particular spatial pattern of population distribution. (shrink)

While many persons within westernised or westernising nations such as the United States of America and South Africa continue to place importance on matters of faith, a growing number of those persons approach matters of faith informally rather than formally and individually rather than institutionally. The implications of this are that among 21st century populations informal religious formation may be as important as or more important than the formation taking place via formal religious channels. A central emphasis of this article (...) is that this is especially true among more socially marginalised populations, not simply because they may not enjoy the same level of access to formal institutions, but also because they may regard those institutions as spiritually and culturally restrictive and exclusionary. The contributions of the article are, firstly, its use of original and unique survey data generated from neighbourhood studies the author directed in low-income contexts within several U.S. cities and within Pretoria, South Africa, and, secondly, its analysis of informal ways the urban poor engage Christian ideas and practices − an aspect of urban religion that has not received adequate scholarly attention.

Many factors complicate the education of urban students. Among them have been issues related to population density; racial, ethnic, cultural, and linguistic diversity; poverty; racism ; and funding levels. Although urban educators have been addressing these issues for decades, placing them under the umbrella of "urban education" and treating them as a specific area of practice and inquiry is relatively recent. Despite the wide adoption of the term a consensus about its meaning exists at only the (...) broadest of levels. In short, urban education remains an ill-defined concept. This comprehensive volume addresses this definitional challenge and provides a 3-part conceptual model in which the achievement of equity for all -- regardless of race, gender, or ethnicity – is an ideal that is central to urban education. The model also posits that effective urban education requires attention to the three central issues that confronts all education systems _accountability_ of individuals and the institutions in which they work, _leadership_, which occurs in multiple ways and at multiple levels, and _learning_, which is the raison d'être of education. Just as a three-legged stool would fall if any one leg were weak or missing, each of these areas is essential to effective urban education and affects the others. (shrink)

For achieving the sustainable development goals, green development has been raised to a high position for cities in China. The economic development in Northwest China is slow, the ecological environment is fragile, and the mineral resources are rich. Only through green development can we realize the comprehensive income of regional production development, rich life, and good ecology. This paper measures the green development efficiency of 30 prefecture-level cities in Northwest China by using DEA-SBM model of unexpected output, explores the differences (...) and causes of green development efficiency from the perspective of time and space through convergence coefficient, coordination matrix, GIS, and other methods, and empirically tests the impact of industrial structure, technological progress, and other driving factors on green development efficiency by using panel Tobit model. The results show that, on the whole, the efficiency of green development in Northwest China is low, path dependence is serious and unbalanced, the coordinated development effect of different regions is weak, and the spillover effect of core urban agglomerations has not been effectively exerted; from the perspective of driving factors, economic development, population density, traffic situation, and education investment can significantly improve the efficiency of urban green development, and the second is that the proportion of industries significantly hinders the improvement of green development efficiency, while the impact of scientific and technological innovation is not significant. Based on the empirical results, this paper believes that the harmonious development of natural environment and economic society can be realized only by improving the coordinated development effect among cities, implementing the optimization and upgrading of industrial structure, introducing excellent talents, and promoting the technological upgrading.

Many older people need external support for their daily living. A large minority of older adults with low or modest pension incomes face financial strains from the high cost of illness, and many older people in urban areas live in social isolation. Indeed, population aging has become a policy topic of concern. The policy debate since the end of the twentieth century about the future of public pensions and health and long‐term care programs has increasingly framed the growing (...) numbers of older people in alarmist terms. Unfounded claims about the unaffordability and unsustainability of social policies supporting older people have become common currency, often disguised as concerns about intergenerational justice. Such claims and concerns hinder clear thinking about proper social and fiscal policies, housing, health care, and labor markets to safeguard the well‐being of older people in aging societies.

Research on urban agglomerations from the perspective of network spatial structure is important to promote their sustainable development. Based on online and traditional data, this paper first improves three aspects of the traditional spatial gravity model—city quality, the gravitation coefficient, and city distance—considering urban center functional intensity and population mobility tendencies. The resulting improved directional gravity model is applied to analyze the structure of the city network for two urban agglomerations in China, the Beijing-Tianjin-Hebei urban (...) agglomeration and the Yangtze River Delta urban agglomeration. The results of the study are as follows: the existing urban connections have obvious hierarchies and imbalances, with the YRDUA urban hierarchical connections being of larger scale. Cities are closely connected, but city networks are unbalanced, though the YRDUA has more balanced urban development. Each node city has a clear radiation range limit, and spatial distance remains an important constraint on urban connections. The backbone network of the BTHUA has a triangular shape and trends toward a “sparse north and dense south,” while the YRDUA is characterized by multiple axes and an overall distribution that trends toward a “dense north and sparse south.” Cities with poor comprehensive strength are more likely to be captured, forming an attract and be attracted relationship. The BTHUA and the YRDUA each form three communities. (shrink)

As world food and fuel prices threaten expanding urban populations, there is greater need for the urban poor to have access and claims over how and where food is produced and distributed. This is especially the case in marginalized urban settings where high proportions of the population are food insecure. The global movement for food sovereignty has been one attempt to reclaim rights and participation in the food system and challenge corporate food regimes. However, given its (...) origins from the peasant farmers' movement, La Via Campesina, food sovereignty is often considered a rural issue when increasingly its demands for fair food systems are urban in nature. Through interviews with scholars, urban food activists, non-governmental and grassroots organizations in Oakland and New Orleans in the United States of America, we examine the extent to which food sovereignty has become embedded as a concept, strategy and practice. We consider food sovereignty alongside other dominant US social movements such as food justice, and find that while many organizations do not use the language of food sovereignty explicitly, the motives behind urban food activism are similar across movements as local actors draw on elements of each in practice. Overall, however, because of the different histories, geographic contexts, and relations to state and capital, food justice and food sovereignty differ as strategies and approaches. We conclude that the US urban food sovereignty movement is limited by neoliberal structural contexts that dampen its approach and radical framework. Similarly, we see restrictions on urban food justice movements that are also operating within a broader framework of market neoliberalism. However, we find that food justice was reported as an approach more aligned with the socio-historical context in both cities, due to its origins in broader class and race struggles. (shrink)

Numerous studies have shown almost uniformly positive opinions among patients and physicians regarding theconceptof advance directives (either a healthcare proxy or living will). Several of these studies have also shown that the actual use of advance directives is significantly lower than this enthusiasm would suggest, but they have not explained the apparent discordance. Nor have researchers explained why members of minority groups are much less likely to complete advance directives than are white patients. In this study, we used a focus (...) group methodology to examine the ways in which diverse populations of patients view the medical, philosophical, and practical issues surrounding advance directives. We were motivated by the significantly lower prevalence of advance directives among African-American and Hispanic patients at one urban teaching hospital (18% for Caucasians, 4% for African-Americans, and 2% for Hispanics). Our premise was that African-American and Hispanic populations, who have had higher rates of morbidity and mortality across numerous disease categories, and historically have had limited access to care and opportunities to discuss health concerns, may be more suspicious about the right of autonomy that an advance directive is designed to ensure.

Urban agriculture in Cuba has rapidly become a significant source of fresh produce for the urban and suburban populations. A large number of urban gardens in Havana and other major cities have emerged as a grassroots movement in response to the crisis brought about by the loss of trade, with the collapse of the socialist bloc in 1989. These gardens are helping to stabilize the supply of fresh produce to Cuba's urban centers. During 1996, Havana's (...) class='Hi'>urban farms provided the city's urban population with 8,500 tons of agricultural produce, 4 million dozens of flowers, 7.5 million eggs, and 3,650 tons of meat.

This article explores the systems utilized by Cuba's urban farmers, and the impact that this movement has had on Cuban food security. (shrink)

Contemporary epidemiological methods testing the associations between green space and psychological well-being treat all vegetation cover as equal. However, there is very good reason to expect that variations in ecological "quality" (number of species, integrity of ecological processes) may influence the link between access to green space and benefits to human health and well-being. We test the relationship between green space quality and restorative benefit in an inner city urban population in Bradford, UK. We selected 12 urban (...) parks for study where we carried out botanical and faunal surveys to quantify biodiversity and assessed the site facilities of the green space (cleanliness, provision of amenities). We also conducted 128 surveys with park users to quantify psychological restoration based on four self-reported measure of general restoration, attention-grabbing distractions, being away from everyday life, and site preference. We present three key results. First, there is a positive association between site facilities and biodiversity. Second, restorative benefit is predicted by biodiversity, which explained 43% of the variance in restorative benefit across the parks, with minimal input from other variables. Third, the benefits accrued through access to green space were unrelated to age, gender, and ethnic background. The results add to a small but growing body of evidence that emphasise the role of nature in contributing to the well-being of urban populations and, hence, the need to consider biodiversity in the design of landscapes that enhance multiple ecosystem services.

Urbanization affects concurrent human-animal interactions as a result of altered resource availability and land use pattern, which leads to considerable ecological consequences. While some animals have lost their habitat due to urban encroachment, few of them managed to survive within the urban ecosystem by altering their natural behavioral patterns. The feeding repertoire of folivorous colobines, such as gray langur, largely consists of plant parts. However, these free-ranging langurs tend to be attuned to the processed high-calorie food sources to (...) attain maximum benefits within the concrete jungle having insignificant greenery. Therefore, besides understanding their population dynamics, the effective management of these urbanized, free-ranging, non-human primate populations also depends on their altered feeding habits. Here, we have used a field-based experimental setup that allows gray langurs to choose between processed and unprocessed food options, being independent of any inter-specific conflicts over resources due to food scarcity. The multinomial logit model reveals the choice-based decision-making of these free-ranging gray langurs in an urban settlement of West Bengal, India, where they have not only learned to recognize the human-provisioned processed food items as an alternative food source but also shown a keen interest in it. However, such a mismatch between the generalized feeding behavior of folivorous colobines and their specialized gut physiology reminds us of Liem's paradox and demands considerable scientific attention. While urbanization imposes tremendous survival challenges to these animals, it also opens up for various alternative options for surviving in close proximity to humans which is reflected in this study, and could guide us for the establishment of a sustainable urban ecosystem in the future.

This paper explores the influence and use of agrarian thought on collective understandings of food practices as sources of ethical and communal value in urban contexts. A primary proponent of agrarian thought that this paper engages is Paul Thompson and his exceptional book, The Agrarian Vision. Thompson aims to use agrarian ideals of agriculture and communal life to rethink current issues of sustainability and environmental ethics. However, Thompson perceives the current cultural mood as hostile to agrarian virtue. There are (...) two related claims of this paper. The first argues that contrary to Thompson’s perception of hostility, agrarian thought is popularly and commercially mobilized among urban populations. To establish this claim I extend Charles Taylor’s notion of a social imaginary and suggest that urban agriculture can be theorized as an agrarian imaginary. Entwined with the first claim is the second, that proponents selectively use agrarian history to overemphasis a narrative of virtue while ignoring or marginalizing historical practices of agrarian violence, exclusion and dispossession. I do not discount or deny the significance of agrarian virtue. By situating agrarian thought within a clearer virtue ethics framework and acknowledging potential manifestation of agrarian vice, I suggest that the idea of agrarian virtue is strengthened.

The article presents the reasons for which the issue of providing housing to low-income citizens has been a real challenge in Addis Ababa during the recent years and will continue to be, given that its population is growing extremely fast. It examines the tensions between the universal aspirations and the local realities in the case of some of Ethiopia’s most ambitious mass pro-poor housing schemes, such as the “Addis Ababa Grand Housing Program” (AAGHP), which was launched in 2004 and (...) was integrated in the “Integrated Housing Development Program” (IHDP) in 2006. The article argues that the quotidian practices of communities and their socio-economic and cultural characteristics are related to the spatial attributes of co-housing practices. Drawing upon the idea that there is a mutual correspondence between social and spatial structures, it places particular emphasis on the analysis of the IHDP and aims to show that to shape strategies that take into account the social and cultural aspects of daily life of the poor citizens of Addis Ababa, it is pivotal to invite them to take part in the decision-making processes regarding their resettlement. Departing from the fact that a large percentage of the housing supply in Addis Ababa consists of informal unplanned housing, the article also compares the commoning practices in kebele houses and condominium units. The former refers to the legal informal housing units owned by the government and rented to their dwellers, whereas the latter concerns the housing blocks built in the framework of the IHDP for the resettlement of the kebele dwellers. The article analyzes these processes of resettlement, shedding light of the fact that kebele houses were located at the inner city, whereas the condominiums are located in the suburbs. Despite the fact that the living conditions in the condominium units are of a much higher quality than those in the kebele houses, their design underestimated or even neglected the role of the commoning practices. The article highlights the advantages of commoning practices in architecture and urban planning, and how the implementation of participation-oriented solutions can respond to the difficulties of providing housing. It argues that understanding the significance of the endeavors that take into account the opinions of dwellers during the phase of decision-making goes hand in hand with considering commoning practices as a source of architecture and urban planning frameworks for low-cost housing in this specific context. The key argument of the article is that urban planning and architecture solutions in Addis Ababa should be based on the principles of the so-called “negotiated planning” approach, which implies a close analysis of the interconnections between planning, infrastructure, and land.

The proportion of the world’s population living in urban areas is increasing rapidly, with the vast majority of this growth in developing countries. As growing populations in urban areas demand greater food supplies, coupled with a rise in rural to urban migration and the need to create livelihood options, there has been an increase in urban agriculture worldwide. Urban agriculture is commonly discussed as a sustainable solution for dealing with gaps in the local food (...) system, and proponents often highlight the many social, environmental, and economic benefits. We argue that the sustainability of urban agriculture should not be assumed. There is a need for research to take a bottom-up approach, exploring the influence that city-level conditions have on livelihood decisions by farmers and how this shapes the practice of urban agriculture. This paper uses a case study for an in-depth look at urban agriculture in Delhi, India to understand from the farmers’ perspective how urban agriculture is practiced and what factors influence farmers’ livelihood decisions. Using a team-based, multi-method Rapid Assessment Process, data were collected through preliminary key informant interviews, field observations, semi-structured interviews with urban farmers, and geographic information systems mapping. This research provides an in-depth description of market-oriented urban agriculture in a developing country, explores how farmers’ livelihood decisions are embedded in the urban context, and discusses the potential of urban agriculture as a sustainable city-system.

Urban space is the spatial projection of various social and economic activities. Given the complexity of urban functions and the ongoing expansion of urban areas, the spatial differentiation of various economic activities within cities tends to become more and more clear; moreover, there tends to be spatial inequalities in resource allocation. Taking Beijing as an example, this study develops a spatial accessibility model at the town level by integrating the spatial distribution of economic activities with the transport (...) system and evaluating the accessibility to various economic activities. The equality of the residents’ economic-related travel activity is also evaluated in line with the population distribution. The results show that the accessibility to economic activities generally decreases in going from the urban center to the peripheral suburbs, and this “core to edge” difference is readily apparent. In general, residents tend to choose areas to settle in which have a high degree of accessibility, however, the attractiveness of accessibility is constrained within certain limits, as evidenced by a reduction of population in the center of Beijing. Additionally, there are inequalities with respect to traveling experiences. For instance, 27.8% of residents experience very convenient travel conditions, mostly in the Xicheng, Dongcheng, and Haidian districts, and this equates to a high level of accessibility; about half of the residents in Beijing live in areas ranked as being of medium accessibility and where the distribution of economic activities and transportation facilities are insufficient. Residents living in the outlying Changping, Mentougou, Shunyi, and Fangshan districts have relatively poor access to transportation indicating a low level of accessibility. Overall, the evaluation method for spatial equality considers comprehensively the distribution of economic activities, transportation, and population distribution and can provide a reference framework for optimization of the urban spatial structure to improve urban spatial equality.

Moates, Anne Most of the Australian population is concentrated in urban areas and larger regional centres. There is a belief that living in rural areas is healthier than city living. However, the opposite is generally true. Contributing factors are lack of access to health care services, attitudes to health care, cost of basic amenities and the degree of remoteness.

Previous studies have found that individuals from rural areas in Malaysia and in El Salvador prefer heavier women than individuals from urban areas. Several explanations have been proposed to explain these differences in weight preferences but no study has explored familiarity as a possible explanation. We therefore sought to investigate participants’ face preferences while also examining the facial characteristics of the actual participants. Our results showed that participants from rural areas preferred heavier-looking female faces than participants from urban (...) areas. We also found that the female faces from the rural areas were rated as looking heavier than the female faces from the urban areas. Our findings are consistent with the hypothesis that familiarity may be contributing to the differences found in face preferences between rural and urban areas given that people from rural and urban areas are exposed to different faces.

Over half of the world's population (3 billon people) now lives in urban environments. The combination of people, industry, and commerce enmeshed in environments over-determined by plans, designs, and configurations that continue to emphasize ease, efficiency, and spatial sprawl over ecological constraints and sustainability help to make urban environments the primary contributors to multiple types of ecological degradation. With this in mind, urban environments demand greater sustained theoretical and practical attention than has been and is the (...) norm under status quo approaches to urbanism that pay little regard to ecological constraints and under traditional models of environmentalism informed by an anti-urban bias. Fortunately, an emerging form of urban environmentalism exists that recognizes the central ecological role of urban environments. This emerging form of urban environmentalism also recognizes urban environments to be the places where environmental problems are often most severe and where environmental solutions are in most need of immediate implementation. The upshot of this dual recognition is that it is accompanied by a growing dual awareness of urban environmental problems and solutions. In this paper I argue that despite this dual recognition and awareness, a paradoxical form of inaction is the norm when it comes to implementing urban environmental solutions. I explain why this is the case by outlining what I call the paradox of urban environmentalism. I explain why the paradox should be considered one of the most significant problems of this new environmental century as well as that frame which opens the door to a new sense of what is possible in urban environments. In the process of considering what is possible, I arrive at some preliminary conclusions about a possible methodological role philosophers can play in helping to address this paradoxical inaction in the hopes of bringing about more sustainable urban environments.
