Selection and Optimization of Regional Economic Industrial Structure Based on Fuzzy k-Means Clustering Algorithm.

Learning about the regional business model is essential for the sustainable development of the regional economy. From the perspective of urban renewable energy, city A is the product of energy development. This paper analyzes the current situation and existing problems of the industrial model of city A through fuzzy k-means clustering algorithm. The results show that although the optimization of industrial structure in city A has achieved some results, the more intuitive problems mainly include low labor productivity of the primary industry, strong resource dependence, insufficient extension of industrial chain, and slow development of technology intensive industries. This paper uses fuzzy k-means clustering algorithm to select the leading industries from the perspective of the current situation of leading industries, urban development pattern, and regional policies in city A. The results show that, as a renewable resource-based city, the leading industries suitable for the current development of city A include manufacturing, power, alkali gas and water production and supply, transportation, warehousing and postal industry, leasing, and business services. The results of fuzzy k-means clustering algorithm are quite excellent, and the accuracy rate is 93.3%. This paper uses the grey dynamic linear programming model to predict the future development of the Urban A business model and combines the selection of key functions to obtain the best business model: deep and efficient technical equipment as a good goal, achieved through regional logistics, transportation, new services, etc., to enhance the output value of the tertiary industry in city A and optimize the internal structure of the secondary industry in city A.

Identification and analysis of urban functional area in Hangzhou based on OSM and POI data.

The accurate identification of urban functional areas is of great significance for optimizing urban spatial structure, rationally allocating spatial elements, and promoting the sustainable development of the city. This paper proposes a method to precisely identify urban functional areas by coupling Open Street Map (OSM) and Point of Interest (POI) data. It takes the central urban area of Hangzhou as a case study to analyze the spatial distribution characteristics of the functional areas. The results show that: (1) The central urban areas of Hangzhou are divided into 21 functional areas (6 single functional areas, 14 mixed functional areas and 1 comprehensive functional area). (2) The single functional areas and the mixed functional areas show the geographical distribution characteristics of the looping stratification, which means "Core-periphery" differentiation is obvious, and the comprehensive functional area is relatively scattered. (3) The mixed degree of regional function with ecological function and production function is low while comprehensive functional areas are usually associated with higher potential and vitality. (4) The identification results are in great agreement with the actual situation of Hangzhou central urban area, and the method is feasible. Therefore, this paper can provide a reference for urban development planning and management.

Using 311 data to develop an algorithm to identify urban blight for public health improvement.

The growth of administrative data made available publicly, often in near-real time, offers new opportunities for monitoring conditions that impact community health. Urban blight-manifestations of adverse social processes in the urban environment, including physical disorder, decay, and loss of anchor institutions-comprises many conditions considered to negatively affect the health of communities. However, measurement strategies for urban blight have been complicated by lack of uniform data, often requiring expensive street audits or the use of proxy measures that cannot represent the multifaceted nature of blight. This paper evaluates how publicly available data from New York City's 311-call system can be used in a natural language processing approach to represent urban blight across the city with greater geographic and temporal precision. We found that our urban blight algorithm, which includes counts of keywords ('tokens'), resulted in sensitivity ~90% and specificity between 55% and 76%, depending on other covariates in the model. The percent of 311 calls that were 'blight related' at the census tract level were correlated with the most common proxy measure for blight: short, medium, and long-term vacancy rates for commercial and residential buildings. We found the strongest association with long-term (>1 year) commercial vacancies (Pearson's correlation coefficient = 0.16, p < 0.001). Our findings indicate the need of further validation, as well as testing algorithms that disambiguate the different facets of urban blight. These facets include physical disorder (e.g., litter, overgrown lawns, or graffiti) and decay (e.g., vacant or abandoned lots or sidewalks in disrepair) that are manifestations of social processes such as (loss of) neighborhood cohesion, social control, collective efficacy, and anchor institutions. More refined measures of urban blight would allow for better targeted remediation efforts and improved community health.

Health versus other sectors: Multisectoral resource allocation preferences in Mukono district, Uganda.

OBJECTIVES: To elicit citizen preferences for national budget resource allocation in Uganda, examine respondents' preferences for health vis-à-vis other sectors, and compare these preferences with actual government budget allocations. METHODS: We surveyed 432 households in urban and rural areas of Mukono district in central Uganda.We elicited citizens' preferences for resource allocation across all sectors using a best-worst scaling (BWS) survey. The BWS survey consisted of 16 sectors corresponding to the Uganda national budget line items. Respondents chose, from a subset of four sectors across 16 choice tasks, which sectors they thought were most and least important to allocate resources to. We utilized the relative best-minus-worst score method and a conditional logistic regression to obtain ranked preferences for resource allocation across sectors. We then compared the respondents' preferences with actual government budget allocations. RESULTS: The health sector was the top ranked sector where 82% of respondents selected health as the most important sector for the government to fund, but it was ranked sixth in national budget allocation, encompassing 6.4% of the total budget. Beyond health, water and environment, agriculture, and social development sectors were largely underfunded compared to respondents' preferences. Works and transport, education, security, and justice, law and order received a larger share of the national budget compared to respondents' preferences. CONCLUSIONS: Among respondents from Mukono district in Uganda, we found that citizens' preferences for resource allocation across sectors, including for the health sector, were fundamentally misaligned with current government budget allocations. Evidence of respondents' strong preferences for allocating resources to the health sector could help stakeholders make the case for increased health sector allocations. Greater investment in health is not only essential to satisfy citizens' needs and preferences, but also to meet the government's health goals to improve health, strengthen health systems, and achieve universal health coverage.

Contribution analysis to analyze the effects of the health impact assessment at the local level: A case of urban revitalization.

The health impact assessment (HIA) is a tool used to estimate the potential impact on health of non-health-related proposals prior to implementation. While it is increasingly used in Quebec, Canada, studies have not analyzed its medium-term impacts and potential long-term impacts. We conducted a contribution analysis using in-depth interviews with key stakeholders, as well as documents, observation and images related to HIA in order to analyze its impacts on the revitalization of road infrastructure, parks and green spaces, and residential housing. Our analysis not only reflects on the decision-making process through the adoption and implementation of HIA recommendations, but also on the link between actions implemented in the field and health outcomes.

Development of an Interprofessional Home Healthcare Management Service: Within an Urban Housing Development.

In response to the need for increased access to primary care services for a low-income, at-risk community, two local universities partnered with a nonprofit Housing and Urban Development affiliated provider of affordable housing to launch a primary care clinic within an urban public housing community. Although the establishment of this clinic represented progress in meeting many healthcare needs of the target population, an interprofessional team also identified a need for the initiation of a new home-based service line. The goal of this project was to establish an innovative, sustainable, and cost-effective healthcare delivery method that would improve the health of this population. The project focused on a literature review, needs-assessment, and development of a comprehensive medical home visit program to serve the homebound, frail elderly, and other at-risk adults with complex medical conditions who reside in this community. The medical needs of potential recipients were assessed by conducting interviews with key support staff including a health service coordinator, health advocates, and housing provider service coordinators. Residents were also interviewed using a newly developed health perception and information survey. The data derived from the needs-assessment and pertinent literature were used to draft an initial program guideline. Because the needs-assessment indicated this population would not derive maximum benefit from a traditional house calls program, the project team developed a Home Healthcare Management service with an expanded scope to provide enhanced care coordination, house visits (medical and nonmedical), and community outreach.

Contribution to healthy places: Risks of equity free health impact assessment.

While health equity is central to health impact assessment [HIA], in reality, less is known about potential impacts of equity-free HIA on social inequalities. We assessed equity-free HIA case in a small city east of Montreal, which took place in a context of urban revitalization. We applied a combination of a quantitative review of community characteristics with a qualitative descriptive approach based on in-depth semi-structured interviews and a focus group with multiple stakeholders to shed light on the pitfalls of equity-free HIA. Our results pointed to gentrification process with a gradual relocation of low-income residents in the end. To mitigate mediating circumstances of gentrification and displacement, the municipality should support social housing or at least should ensure rent stabilization ordinance.

Managing the hope and worry of housing renewal-supporting well-being in the emerging community.

ISSUE ADDRESSED: Housing renewal is a common urban housing and development strategy internationally. An intended result is increased social inclusion and well-being of residents through public housing de-concentration. In this study, we examined challenges encountered during the process of housing renewal from the perspectives of community-based staff and volunteers. METHODS: We conducted semi-structured qualitative interviews with housing and community workers, service managers and community volunteers who were working with residents experiencing housing renewal in an outer metropolitan estate in New South Wales. We analysed the data thematically. RESULTS: Seventeen participants were interviewed in a mix of individual and group interviews. Housing workers uncovered substantial resident health and social support needs during housing assessments. Promoting access to services and supporting the mental health and social connectedness of residents into the future were seen as key goals and challenges. However, lack of clarity on which services and community resources would exist in the new neighbourhood at the completion of the renewal project made this more difficult, particularly when supporting the social housing residents who were remaining in the changing community. CONCLUSIONS: Supporting the mental health and well-being of residents experiencing housing renewal is an important role of community-based workers, volunteers and service providers. This includes facilitating access to health care and other services and promoting social connectedness in the emerging community. Increased clarity on what community resources and services will be available subsequent to redevelopment will assist in these aims. SO WHAT?: Early knowledge of what community resources and services will be in place long term in communities undergoing housing renewal will allow staff and volunteers to better support the health and well-being of residents.

Aging in Place in Gentrifying Neighborhoods: Implications for Physical and Mental Health.

Background and Objectives: In the United States, the older adult population and the proportion of neighborhoods experiencing gentrification are both growing. However, there is limited scholarship on the effects of gentrification on older adults, with most work focusing on those who leave rather than stay. This study examines the effects of remaining in a gentrifying neighborhood on older adults' self-rated health and mental health, with particular attention to outcomes for those who are economically vulnerable. Research Design and Methods: Data are from 6,810 community-dwelling respondents in metropolitan areas from the first wave of the National Health & Aging Trends Study combined with the 1970-2010 National Neighborhood Change Database. We estimate the effects of gentrification on self-rated health and mental health separately using a quasi-experimental approach and comparing two methods: matching design and linear regression. Results: Economically vulnerable older adults in gentrifying neighborhoods reported higher self-rated health than economically vulnerable older adults in low-income neighborhoods. Both economically vulnerable and higher-income older adults in gentrifying neighborhoods had more depression and anxiety symptoms than those living in more affluent areas. Higher-income older adults in gentrifying neighborhoods had poorer mental health than their counterparts in low-income neighborhoods. Discussion and Implications: Findings call attention to the complexity of gentrification, and the need for more research examining how the intersection of neighborhood and individual characteristics influences older adults' health. Results reinforce the need for neighborhood-level interventions as well as relocation support to promote health in later life and caution against an overemphasis on aging in place.

Neoliberalization's Propagation of Health Inequity in Urban Rebuilding Processes: The Dependence on Context and Path.

This article will discuss how neoliberal processes during urban redevelopment sustain and increase health inequities through uneven wealth accumulation and development. It will use examples of urban development in Baltimore, Maryland, United States, to highlight how key neoliberal strategies of territorial development, economic development, and place promotion- mediated through the process of creative destruction-result in uneven development and wealth accumulation, which in turn result in health inequities. The history of rebuilding processes in Baltimore offers insight into the context and path-dependency of current neoliberalization rebuilding processes and current health inequities.

Urban regeneration as population health intervention: a health impact assessment in the Bay of Pasaia (Spain).

BACKGROUND: An important health issue in urban areas is how changes arising from the regeneration of city-areas affect social determinants of health and equity. This paper examines the impacts attributable to a new fish market and to delays in the regeneration of a port area in a deteriorated region of the Bay of Pasaia (Spain). Potential differential impacts on local residents and socially vulnerable groups were evaluated to determine health inequalities. METHODS: An in-depth, prospective and concurrent Health-Impact-Assessment (HIA) focused on equity was conducted by the regional Public Health Department, following the Merseyside guidelines. Data from different sources was triangulated and impacts were identified using qualitative and quantitative methods. RESULTS: The intervention area is characterised by poor social, environmental, and health indicators. The distinctness of the two projects generates contrasting health and inequality impacts: generally positive for the new fish market and negative for the port area. The former creates recreational spaces and improves urban quality and social cohesion. By contrast, inaction and stagnation of the project in the port area perpetuates deterioration, a lack of safety, and poor health, as well as increased social frustration. CONCLUSIONS: In addition to assessing the health impacts of both projects this HIA promoted intersectoral partnerships, boosted a holistic and positive view of health and incorporated health and equity into the political discourse. Community-level participatory action enabled public health institutions to respond to new urban planning challenges and responsibilities in a more democratic manner.

A South African Municipality Mapping the Way Forward for Social Inclusion Through Universal Design.

Since becoming a democracy, South African legislation has changed. The South African Constitution and legislation governing the structures and mandate of the different spheres of government aim towards municipalities needing to become more developmental in the way it serves the community with a specific focus on the poor and vulnerable. It sets ideals to overcome the inheritance of the past. However, how to do this is sometimes still unclear. This paper is a case study illustrating how Stellenbosch Municipality overcame obstacles of perceived legislative restrictions, silo operations and antiquated thinking, working towards social inclusion for all its citizens. In moving away from disability accessibility and embracing universal access as a way in which to deliver basic services, Stellenbosch discovered the beginning of the process of overcoming the negative legacy of the past. Understanding the Universal Design principles and approach illustrated how South African municipalities can promote the concept of our rainbow nation as envisioned in the Constitution.

Using Optimal Land-Use Scenarios to Assess Trade-Offs between Conservation, Development, and Social Values.

Development of land resources can contribute to increased economic productivity but can also negatively affect the extent and condition of native vegetation, jeopardize the persistence of native species, reduce water quality, and erode ecosystem services. Spatial planning must therefore balance outcomes for conservation, development, and social goals. One approach to evaluating these trade-offs is scenario planning. In this paper we demonstrate methods for incorporating stakeholder preferences into scenario planning through both defining scenario objectives and evaluating the scenarios that emerge. In this way, we aim to develop spatial plans capable of informing actual land-use decisions. We used a novel approach to scenario planning that couples optimal land-use design and social evaluation of environmental outcomes. Four land-use scenarios combined differences in total clearing levels (10% and 20%) in our study region, the Daly Catchment Australia, with the presence or absence of spatial precincts to concentrate irrigated agriculture. We used the systematic conservation planning tool Marxan with Zones to optimally plan for multiple land-uses that met objectives for both conservation and development. We assessed the performance of the scenarios in terms of the number of objectives met and the degree to which existing land-use policies were compromised (e.g., whether clearing limits in existing guidelines were exceeded or not). We also assessed the land-use scenarios using expected stakeholder satisfaction with changes in the catchment to explore how the scenarios performed against social preferences. There were a small fraction of conservation objectives with high conservation targets (100%) that could not be met due to current land uses; all other conservation and development objectives were met in all scenarios. Most scenarios adhered to the existing clearing guidelines with only marginal exceedances of limits, indicating that the scenario objectives were compatible with existing policy. We found that two key stakeholder groups, agricultural and Indigenous residents, had divergent satisfaction levels with the amount of clearing and agricultural development. Based on the range of benefits and potential adverse impacts of each scenario, we suggest that the 10% clearing scenarios are most aligned with stakeholder preferences and best balance preferences across stakeholder groups. Our approach to scenario planning is applicable generally to exploring the potential conflicts between goals for conservation and development. Our case study is particularly relevant to current discussion about increased agricultural and pastoral development in northern Australia.

Documenting a long-term development model in the slums of Delhi.

BACKGROUND: Achieving development outcomes requires the inclusion of marginalised populations that have the least opportunity to participate in and benefit from development. Slum dwellers often see little of the 'urban advantage', suffering more from infectious diseases, increasing food costs, poor access to education and health care, inadequate water and sanitation, and informal employment. A recent Cochrane Review of the impact of slum upgrading strategies found a dearth of unbiased studies, making it difficult to draw firm conclusions. The Review calls for greater use of process data, and qualitative alongside quantitative methods of evaluation. India is a lower middle income nation with large gender disparities and around 65 million slum inhabitants. The Asha Community Health and Development Society, a non-governmental organisation based in Delhi, has delivered a multi-sectoral program across 71 slums since 1988. This article reports on a mixed-method study to document measureable health and social impacts, along with Asha's ethos and processes. METHODS: Several observational visits were made to 12 Asha slums where informal discussions were had with staff and residents (n = 50). Asha data records were analysed for change over time (and differences with greater Delhi) in selected indicators (maternal-child health, education, child sex ratio) using descriptive statistics. 34 semi-structured individual/small group interviews and 14 focus group discussions were held with staff, residents, volunteers, elected officials, civil servants, bankers, diplomats, school principals, slumlords and loan recipients (n = 147). RESULTS: Key indicators of health and social equity improved over time and compared favourably with those for greater Delhi. The Asha model emphasises rights, responsibilities, equity and non-violence. It employs strategies characterised by long-term involvement, systematic protocols and monitoring, development of civil society (especially women's and children's groups) to advocate for rights under the law, and links with foreign volunteers and fund-raisers. Stakeholders agreed that changes in community norms and living conditions were at least partly attributable to the Asha model. CONCLUSIONS: While lacking a control group or complete baseline data, evidence suggested substantial improvements in slum conditions and social equity. The Asha model offers some lessons for slum (and broader) development.

Spatial and temporal variations of ecosystem service values in relation to land use pattern in the Loess Plateau of China at town scale.

Understanding the relationship between land use change and ecosystem service values (ESVs) is the key for improving ecosystem health and sustainability. This study estimated the spatial and temporal variations of ESVs at town scale in relation to land use change in the Loess Plateau which is characterized by its environmental vulnerability, then analyzed and discussed the relationship between ESVs and land use pattern. The result showed that ESVs increased with land use change from 1982 to 2008. The total ESVs increased by 16.17% from US$ 6.315 million at 1982 to US$ 7.336 million at 2002 before the start of the Grain to Green project, while increased significantly thereafter by 67.61% to US$ 11.275 million at 2008 along with the project progressed. Areas with high ESVs appeared mainly in the center and the east where largely distributing orchard and forestland, while those with low ESVs occurred mainly in the north and the south where largely distributing cropland. Correlation and regression analysis showed that land use pattern was significantly positively related with ESVs. The proportion of forestland had a positive effect on ESVs, however, that of cropland had a negative effect. Diversification, fragmentation and interspersion of landscape positively affected ESVs, while land use intensity showed a negative effect. It is concluded that continuing the Grain to Green project and encouraging diversified agriculture benefit to improve the ecosystem service.

Ross River virus risk associated with dispersal of Aedes (Ochlerotatus) camptorhynchus (Thomson) from breeding habitat into surrounding residential areas: muddy lakes, Western Australia.

Rapid population growth in Western Australia has resulted in increased development of land for residential housing, and new developments are often proposed close to water because of intrinsic aesthetic values. However, this placement may place future residents at risk of mosquito-borne disease, of which Ross River virus (RRV) disease is the most common in Australia. Mosquito dispersal data were combined with a spatial analysis of human RRV cases to show that mosquitoes dispersed readily from larval habitat into surrounding low- and high-density residential areas and that residents living within 2 km of mosquito breeding habitat had a significantly higher rate of RRV disease. This finding highlights the importance of planning authorities in state and local governments to consider the implications of mosquito-borne disease risks when assessing residential development applications.

Participatory and evidence-based recommendations for urban redevelopment following natural disasters: older adults as policy advisers.

AIM: To develop community-generated recommendations to inform urban environmental remediation following earthquakes in Christchurch, New Zealand, and share these with local decision-makers during a participatory action research process. METHODS: This study employed three focus group discussions to critique mixed-methods and multiphase results and develop evidence-based recommendations. Participants included 30 volunteers and 8 knowledgeable advisers aged 65 years and older. RESULTS: Participant recommendations addressed the remediation of earthquake-affected suburbs, access to transportation, age-friendly design, safer communities, resilient support agencies, and restoration of resources for social and cultural activities. CONCLUSION: Older collaborators identified salient barriers to active ageing and options for post-earthquake redevelopment that had not previously been considered in research or policy. Independently living older adults are well placed to work with researchers to develop recommendations to improve the urban environment following natural disasters as well as in times of relative stability.

Disasters as an ideological strategy for governing neoliberal urban transformation in Turkey: insights from Izmir/Kadifekale.

Since the turn of the twenty-first century, Turkish cities have undergone large-scale change through a process referred to as urban transformation, involving, notably, the demolition of inner-city low-income settlements. The official authorities and business circles have resorted to various forms of discourse to justify these projects, which have led to the deportation of a significant number of people to peripheral areas. The discourse of 'natural disasters', for example, suggests that urban transformation is necessary to protect people from some pending event. Probably the most effective application of this discourse has occurred in Izmir, where the risk posed by 'landslides' has played a critical role in the settlement demolitions conducted in the huge inner-city neighbourhood of Kadifekale. By examining the case of Kadifekale, this paper provide some insights into how 'natural disasters' serve as a discourse with which to legitimise the neoliberal logic entrenched in the urban transformation process in Turkey.
