广州夏季高温高湿,基于广州城乡老年人的室内环境差异,通过问卷调查了解了116 名广州城乡老年人的室内居住环境, 并对5 户典型城市及5 户典型农村65 岁以上居民住宅的夏季室内环境进行了对比实测研究,测量每户住宅的客厅,卧室和卫 生间的温度、相对湿度及CO2、CO、PM2.5、挥发性有机物浓度。研究表明,广州农村住户夏季主要使用风扇降温,仅有约三 分之一住户同时使用空调,而城市住户均使用空调,大部分住户同时使用风扇;广州农村住户夏季室内平均空气温度比城市住 户低0.8 ℃,平均相对湿度比城市住户高21.6%;通风较差的住户室内CO2 浓度相对较高,所有实测城市及农村住户的CO、 PM2.5 的浓度都低于国家标准规定的极限值;广州城市住户的室内外PM2.5 浓度及室内总挥发性有机物的浓度总体高于农村住户。 广州农村老年人住宅应加强防潮处理,城市老年人住宅应加强通风换气,优选环保家具。     

From income and housing wealth inequalities to emissions inequality: carbon emissions of households in China

The emerging notion of emissions inequality expands the idea of sustainability by incorporating economic opportunity as well as social needs and rights into environmental costs and benefits. In China, increasing inequality among urban households in terms of both income and housing wealth establishes a pattern of social stratification. An understanding of the association of social and environmental inequality is thus critical for urban sustainability. Based on the Chinese urban household survey from 2002 to 2009, this article employs the lifestyle approach to calculate and analyse the inequality of households by direct and indirect carbon emissions. The correlations among carbon emission inequality with income and housing wealth inequality are estimated with a Heckman procedure. We find that not only income distribution but also housing wealth distributionis an important consideration in understanding environmental inequality in China.     

Housing quality and resilience in New Zealand

There is extensive research on the negative health impacts of poor housing quality. However, little is known about the potential health benefits of high-quality housing in poor neighbourhoods. Neighbourhoods with unexpectedly good health outcomes despite high levels of deprivation have been deemed resilient places and housing quality in these areas may be a contributor to this resilience. This study aimed to evaluate whether an indicator of neighbourhood housing quality was associated with a previously quantified resilience index (RINZ) in New Zealand. It was found that areas with high housing quality tended to have higher median income, greater proportions of partnered people and shorter-term residents, and very low proportions of Māori. A positive association was found between housing quality and resilience, after adjustment for deprivation. There was no indication of differences by heterogeneity in housing quality within the aggregate unit of analysis. These findings pose the hypothesis that improving housing quality in similarly deprived areas that have poor health outcomes could potentially boost health. To extend this understanding, further development of a more sophisticated housing quality indicator is recommended.     

The “Pink Pound” in the “Gaybourhood”? Neighbourhood Deprivation and Sexual Orientation in Scotland

Abstract

The emergence of geographic concentrations of non-heterosexual individuals – so-called “gaybourhoods” – is often linked to housing, demographic characteristics of the non-straight population and wider discrimination. These neighbourhoods are associated with narratives of gentrification with the non-straight population acting as gentrification pioneers. In popular imagery, non-straight households are typically portrayed with higher disposable income, and more likely to live in owner-occupied apartments in affluent neighbourhoods. This paper presents data from the Scottish Health Survey showing a disproportionate concentration of non-heterosexual people in the most deprived places in Scotland. These neighbourhoods are predominantly peripheral housing estates, dominated by social housing; not gentrifying inner-city neighbourhoods. We use data from the Scottish Health Survey (SHeS) to interrogate individual characteristics that might explain this spatial concentration of residence. We argue this means the narratives of LGBT gentrification and affluence should be regarded with caution given ongoing exclusion and deprivation among the non-heterosexual population.

Favoured Owners,Neglected Tenants: Privatisation of State Owned Housing in Hanoi

This paper presents selected findings from the project ‘Privatisation of public housing in Hanoi, the impacts on housing quality and social equality’ which was financed by the Swedish International Development Authority (SIDA). The project analyses the consequences of privatisation on the housing conditions of those tenants and owners who live in privatised and partly privatised multi-family apartment buildings. This paper focuses on the consequences of privatisation on the housing and living conditions of tenants compared to those of owners, and presents findings. The paper concludes that privatisation actually helps to strengthen the existing inequity between different social groups, in the sense that the privatisation policy supports senior government officials, many of whom are well situated both financially and socially, and ignores poor and low-income households. Privatisation also contributes to enhancing the inequality between better-off housing areas and poorer ones. Mixed ownership, and the lack of regulations about the duties and rights of owners and tenants after privatisation, also lead to serious degradation of common areas in all residential blocks.     

How consumers value healthy houses: a preliminary segmentation of Canadian households

As part of a larger research project which examined the concept of healthy houses in Canada, this study provides a preliminary assessment of potential segments of Canadian householders based on their attitudes about two indoor environmental quality (IEQ) attributes (indoor air quality and lighting). Additionally, concerns about energy efficiency in the home are also addressed. A nationwide survey of households (n = 784) was conducted to search for indications of segments of Canadian householders that value their homes’ indoor environments and energy efficiency, thus addressing issues of consumer interest for healthier homes. Similar groups of householders were derived based on their levels of agreement with a variety of statements regarding some indoor environmental quality attributes and energy efficiency. The specific goals were: (1) to identify segments within Canada which indicate the presence of potential consumers of healthier houses on a broader scale; and (2) to characterize these groups using attitudinal and demographic variables. Segmentation in this study was conducted using a k-means cluster analysis, with the clusters being characterized using demographic and attitudinal information. Results indicated that there is indeed an identifiable segment within the Canadian housing sector for products and services associated with the healthy housing concept. Although housing and policy recommendations are not explicitly made, both private and public stakeholders in the Canadian housing sector could benefit by taking note of these findings.

Housing conditions in Palestinian refugee camps,Jordan

This paper evaluates the quality of housing in a Palestinian refugee camp in Jordan. 1,951,603 refugees live in Jordan, and one fifth live in thirteen refugee camps established following Arab–Israeli conflicts in 1948 and 1967. These camps are characterised by poor living conditions and associated health, social and environmental problems. However, there is scant empirical evidence regarding the quality of the housing in these camps. This paper addresses that gap by reporting on the findings of a questionnaire survey of 186 household units in Baqa’a, the largest of the camps. The quantitative survey was triangulated by a series of extensive fieldwork visits to the area. Findings reveal that the housing in the camp is generally substandard. Poor structure and maintenance are key problems and this paper identifies and discusses various challenges, political and practical, that stand in the way of housing improvements. The paper concludes by suggesting that new models of responsibility need to be forged between the stakeholders in order to break the current stalemate.     

Residential mobility of low-income,subsidized households: a synthesis of explanatory frameworks

Mobility, residential quality, and life outcomes are linked in the literature and these relationships have influenced low-income housing policy. This research investigates the determinants of mobility for households with a federal housing subsidy. Combining unique data from a survey of Housing Choice Voucher households, client program files, and secondary data, this study uses logistic regression to test several explanations for mobility, including the life cycle, housing market perceptions, and perceived and actual neighborhood conditions. The results indicate that a synthesis of explanations produce the best model to predict residential mobility. Neighborhood quality, perceived and actual, variables most strongly influence mobility, but life cycle factors and perception of the local housing market also impact moving choices. At the same time, the results suggest a gap in our understanding of the relationship among individuals’ environmental perceptions, formation of feelings of neighborhood satisfaction, and actual neighborhood conditions. The article concludes with a discussion of the research and policy implications from this study.     

Simulating indoor concentrations of NO(2) and PM(2.5) in multifamily housing for use in health-based intervention modeling

Residents of low-income multifamily housing can have elevated exposures to multiple environmental pollutants known to influence asthma. Simulation models can characterize the health implications of changing indoor concentrations, but quantifying the influence of interventions on concentrations is challenging given complex airflow and source characteristics. In this study, we simulated concentrations in a prototype multifamily building using CONTAM, a multizone airflow and contaminant transport program. Contaminants modeled included PM(2.5) and NO(2) , and parameters included stove use, presence and operability of exhaust fans, smoking, unit level, and building leakiness. We developed regression models to explain variability in CONTAM outputs for individual sources, in a manner that could be utilized in simulation modeling of health outcomes. To evaluate our models, we generated a database of 1000 simulated households with characteristics consistent with Boston public housing developments and residents and compared the predicted levels of NO(2) and PM(2.5) and their correlates with the literature. Our analyses demonstrated that CONTAM outputs could be readily explained by available parameters (R(2) between 0.89 and 0.98 across models), but that one-compartment box models would mischaracterize concentrations and source contributions. Our study quantifies the key drivers for indoor concentrations in multifamily housing and helps to identify opportunities for interventions. PRACTICAL IMPLICATIONS: Many low-income urban asthmatics live in multifamily housing that may be amenable to ventilation-related interventions such as weatherization or air sealing, wall and ceiling hole repairs, and exhaust fan installation or repair, but such interventions must be designed carefully given their cost and their offsetting effects on energy savings as well as indoor and outdoor pollutants. We developed models to take into account the complex behavior of airflow patterns in multifamily buildings, which can be used to identify and evaluate environmental and non-environmental interventions targeting indoor air pollutants which can trigger asthma exacerbations.     

The Creation and Transfer of Housing Wealth: The Experience of Elderly New Zealanders

Issues of housing inequality among the elderly reflect their lifetime experience of the housing and labour markets. In retirement there are thus a range of households formed depending on whether they are asset and income rich or poor. The paper explores the experience of a sample of New Zealand households with respect to their level of accumulation and attitudes towards and practice of intergenerational transfers.     

Residential Mobility and Neighbourhood Outcomes

When households move they obviously weigh both the quality of the house and the quality of the neighbourhood in their decision process. But, to the extent that housing quality and neighbourhood quality are inter-twined it is difficult to disentangle the extent to which households are more focused on one or another of these two components of the choice process. This paper uses both cross-tabulations of the neighbourhood choices, and logit models of the actual choices, to examine the relative roles of neighbourhoods and houses in the choice process. The research is focused on the question of the extent to which households trade up in house quality, or neighbourhood quality or both, as outcomes of residential mobility. The research measures neighbourhood quality in both socio-economic and environmental dimensions. The study shows that many households not only move up in housing quality, but quite consistently also make gains in neighbourhood quality, often independently of gains in housing quality. Not surprisingly, the largest gains in neighbourhood quality are related to households who make the city/suburban transition in their housing moves. The research adds another dimension to the growing and extensive literature on neighbourhoods and their role in residential choice.     

The housing careers of black middle-class residents in a South African metropolitan area

Under apartheid, black African households could not own land or homes in most major urban centres in South Africa. This limited residential mobility and locked many households into state rental accommodation in townships. Homeownership for all South Africans was restored in the mid-1980 s and the Group Areas Act was repealed in 1991. Democracy opened up economic opportunities previously unavailable to black people. This paper investigates the effect on black middle-class South African households’ residential mobility and housing careers. A retrospective cross-sectional survey of 244 such homeowners in the Mangaung Metropolitan Municipality determined their last five housing states. Changes in housing state indicated a steady improvement in housing quality, but tenure changes were not necessarily unidirectional—some had reverted to rental. More than 85% of the study participants had used mortgages to finance their housing career. Very few had financed their housing using own savings, an inheritance, or sale of a previous house, and not many had used the government subsidy. We found that housing careers are bridging the historical spatial racial divide in this municipality.     

Do residents of Affordable Housing Communities in China suffer from relative accessibility deprivation? A case study of Nanjing

Affordable housing has emerged as a key issue in urban development in a wide range of countries. Themes in research on affordable housing development across the world are reviewed. Affordable Housing Communities for low income households have been built on a large scale in developing countries such as China during the last two decades, mainly in urban fringe areas. Evidence on the impact of the location on access of residents to services is rare. Studying Nanjing, this paper compares spatial access to services between Affordable Housing Communities and Other Housing Communities by measuring distances and imputing walking time between residential land parcels and facilities. Affordable Housing Communities have significantly poorer access than Other Housing Communities, because of poor neighbourhood provision of low order services and poor access to high order services. A household survey of Affordable Housing Communities and Other Housing Communities records the daily lives, degrees of satisfaction and community attachments of residents. Residents in affordable housing have low degrees of satisfaction, weak community attachments and desire to move. The findings emphasize that service provision should be planned to keep pace with Affordable housing construction, so that these communities become better places to live.     

Housing conditions in Tunisia: the quantity-quality mismatch

The aim of this paper is to analyze the housing conditions of households in Tunisia, for which we develop an individual indicator of housing adequacy based on dwelling attributes and household size. This indicator has two main advantages: it relies on less arbitrary weights, and it takes the multidimensional housing facets into account in the aggregation process. Using data from Tunisia??s national survey on family health and social transformations for two periods (1994 and 2006), our findings are comparable to those from an arbitrary weighting scheme, the most commonly adopted in the literature of multidimensional well-being. In order to identify households suffering from housing deprivation, we develop five housing deprivation thresholds related to some public health issues. Our results suggest that quality-based efforts should be made to reduce the gap in housing conditions between coastal and inland regions and between urban and rural areas. These efforts should be aimed at reducing housing deprivation and preventing health vulnerability among deprived households.     

Market orientated housing policies and the position of middle-income groups in the Netherlands

As a result of the poor economic climate and neo-liberal policies, the welfare state in many European countries is becoming more residual and is directing its efforts at seriously deprived households. This development is affecting the middle-income groups, who enjoy less protection than before and are therefore forced to become more self-supporting. We can find a good illustration of this trend in the changing position of these groups on the Dutch housing market. The market orientated EU policies are denying middle-income households access to the social rented sector. Meantime, these households are already encountering accessibility problems in the owner-occupied sector due to the economic crisis and the tougher mortgage conditions set by the financial institutions. This paper describes the housing policy changes against this background and analyses the position of middle-income groups on the Dutch housing market.     

Indoor air pollution and self-reported diseases - a case study of NCT of Delhi

People in modern societies often spend 80-90% of their time in indoor environments. It is, therefore, imperative to analyze indoor air quality (IAQ) and its determinants and to consider the contribution of IAQ to possible health outcomes at the household level. Based on empirical data collected from 5949 households from 35 wards of Delhi, it can be summarized that higher proportions of residents live in degraded indoor environmental conditions. The highest risks to health were attached to use of traditional fuels (64%), lack of a kitchen (59%), exposure to environmental tobacco smoke (ETS) (55%), and poor ventilation (55%). Acute respiratory infections (43%) were identified as one of the most prevalent health problems confronted by residents and are strongly associated with use of traditional fuels (adjusted OR 2.7, 95% CI 2.3-3.1). Asthma shows a significant relationship with the use of traditional fuels (adjusted OR 3.8, 95% CI 3.4-4.3), exposure to ETS (adjusted OR 2.5, 95% CI 2.2-2.7), and poor ventilation (adjusted OR 1.26, 95% CI 1.13-1.41). Lung cancer (adjusted OR 1.54, 95% CI 1.38-1.71) and cardiovascular diseases (adjusted OR 2.25, 95% CI 2.01-2.53) also show a strong relationship with ETS exposure. More research is needed. PRACTICAL IMPLICATIONS: The present study can help to create new insights in understanding the gravity of indoor air quality problems in Delhi and can therefore provide interesting material to social scientists, public health officers, planners, and decision makers. The information can be utilized to help formulate comprehensive policies and planning with a humanistic approach for proper urban indoor environments that will be applicable at all administrative levels, viz. local, national, and international, and will also provide an important background for additional research in this area.     

Environmental health problems indoors: A comparison between the 1930's and 1990's

This article is inspired by Ulrich Beck's risk theory, which helps researchers raise new questions about environmental problems. The environmental problem in focus here is poor indoor air quality, particularly as found in Swedish housing. I compare this problem in its contemporary form, sick building syndrome, with indoor air problems of concern during the 1930's. The manner of causal thinking is similar in the two periods, and also the way in which publicity contributes to risk definition. However, housing standards in the 1930's were lower than those of today. The increase in standards was a manifestation of efforts to reduce illness caused by the earlier housing, and involved a re‐distribution of risk that exemplifies Beck's notions regarding the risk society.
