    2011-01-01

    The gentrification that has transformed high-poverty neighbourhoods in US cities since the mid 1990s has been characterised by high levels of state reinvestment. Prominent among public-sector interventions has been the demolition of public housing and in some cases multimillion dollar redevelopment efforts. In this paper, the racial dimension of state-supported gentrification in large US cities is examined by looking at the direct and indirect displacement induced by public housing transformation. The data show a clear tendency towards the demolition of public housing projects with disproportionately high African American occupancy. The pattern of indirect displacement is more varied; public housing transformation has produced a number of paths of neighbourhood change. The most common, however, involve significant reductions in poverty, sometimes associated with Black to White racial turnover and sometimes not. The findings underscore the central importance of race in understanding the dynamics of gentrification in US cities.

    Housing is a fundamental human right and a social determinant of health. According to international law, indigenous peoples are entitled to special housing and health rights and protections. In Israel, land disputes between the government and Arab Bedouins, an indigenous minority, have resulted in ongoing demolitions of Arab Bedouin homes, with thousands more homes threatened. While demolitions could expose this population to mental health problems, research linking house demolition and health is scarce. In this paper, we draw on a human rights perspective to describe this housing instability and examine the association between the threat of house demolition and depressive symptoms (DS) among 464 Arab Bedouin women. We conclude that having their house under threat of demolition is an important determinant of poor mental health among Bedouin women. Any efforts to decrease DS among these women will have to take place alongside efforts to stop this practice.

  3. Housing Abandonment and Demolition: Exploring the Use of Micro-Level and Multi-Year Models

    Full Text Available Policies focusing on enforcing property code violations and the improvement of vacant properties are argued to be more efficacious than demolition policies to fight urban blight. This study applies parcel level data to a multi-year hybrid modeling structure. A fine-grained analysis is conducted on the dynamic patterns of abandonment and demolition for a unique period of four years before and after the City of Buffalo’s stepped-up demolition efforts. Results showed that proximity to vacant and abandoned properties, sustained over the years, had the greatest impact on the possibility of a property being abandoned. The second greatest positive impact on property abandonment was small lot front size. Results also showed that neighborhood vacancy density had the greatest negative impact on surrounding housing sales prices over the years. There was no significant impact of demolition on housing sales prices. These findings suggested that the City should aim to have more incentive programs that are tailored to control the number of vacant properties, rather than focusing primarily on demolition-oriented programs.

    The aim of this study was to examine emotional reactions and coping strategies of Bedouin adolescents against the backdrop of house demolitions in the unrecognized Bedouin villages in the Negev, Israel. We compared two groups of adolescents living in unrecognized Bedouin villages, teenagers whose houses had been destroyed (acute + chronic group) and their counterparts whose houses had not been destroyed (chronic group). Data were gathered during October to December 2010 from 465 Bedouin adolescents aged 13-18 years. Adolescents filled out self-report questionnaires, which included demographics, objective and subjective exposure to house demolition, state anxiety, state anger, psychological distress and Adolescent Coping Scale. Results show differences between the two groups in stress reactions as well as in objective exposure to house demolition with the acute + chronic group reporting more stress and more exposure. In addition, different variables explained stress reactions in the different groups. Whereas in the acute + chronic group, objective and subjective exposure were the most significant variables, in the chronic group, the coping strategies explained stress with more variance. Results are discussed in terms of differentiating between types of stress, chronic versus acute + chronic and in relation to the interactionist model of coping with stress.

    2013-01-01

    Air quality in demolition practices has seldom been evaluated in Iran. Accordingly, we evaluated asbestos exposure among Tehran construction workers during the demolition of old houses. To identify possible sources of asbestos exposure, including thermal insulations, chimney pipes and cement sheets, were all sampled. This study also were taken the personal air samples to evaluate any asbestos exposure during the demolition. The asbestos fibers found in the samples were analyzed by phase-contrast optical microscopy (PCM), scanning electron microscopy (SEM) equipped with an energy dispersive X-ray analysis, and polarized light microscopy (PLM) methods. Personal monitoring of asbestos fiber levels indicated a range from 0.01 to 0.15 PCM f/ml (0.02–0.42 SEM f/ml). The geometric mean concentrations were 0.07 PCM f/ml (0.20 SEM f/ml), which is considerably higher than the threshold limit value (TLV) proposed by American Conference of Governmental Industrial Hygienist (ACGIH), which is 0.1 f/ml. The analysis showed a presence in the bulk samples only chrysotile asbestos and an absence of the other type asbestos. Therefore, it might be expected that workers who worked in the demolition of old houses will suffer from negative effects of exposing to the asbestos fibers. PMID:24292876

  8. Dehomed: the impacts of house demolitions on the well-being of women from the unrecognized Bedouin-Arab villages in the Negev/Israel.

    Science.gov (United States)

    Gottlieb, Nora; Feder-Bubis, Paula

    2014-09-01

    Thirty-five Bedouin-Arab villages in South Israel are regarded illegal settlements by the state. Consequently, the residents׳ homes are subject to demolition. Based on 12 semi-structured multiple-participant interviews, this paper examines the house demolitions׳ impacts on women, in the context of gendered constructions of social roles and space. It highlights that the marginalized position of Arab-Bedouin women - as women in a patriarchal community, as members of a minority within Israeli society, and as residents of an "invisible" settlement - contributes to the devastating effects of the house demolitions. In particular, the study׳s results show that the house demolitions inflict severe personal and collective trauma, amplified by women׳s primary role as mothers. Paradoxically, the very same role also becomes a source of resilience and political resistance, as women act to defend a sense of home and restore family life in the face of state violence.

  15. 禀赋效应、财政幻觉与公共政策——拆迁中情绪事件的行为经济学分析%Endowment Effect, Fiscal Illusion and Public Policy: A Behavioral Economics Analysis on the Contentious Events in Demolition of Houses

    Institute of Scientific and Technical Information of China (English)

    卿志琼

    2011-01-01

    The contentious events in demolition of houses have been often occurring in recent years in China. It is founded that endowment effect and fiscal illusion are the cognitive and institutional basis of the contentious events ; a mechanism that caused these events will be explored in this paper. Endowment effect is psychological basis of contentious events, because homestead is personhood property, so h man's home is his castle, fiscal illusion is the cognitive basis of contentious events, because homestead is taken as fungible property by condemners, so a man's home is his house that is worth of the limited sum of money. Two different evaluated models lies in the same property, so there may be the potential for contentious e- vents in the present institutional environment of China. There are multi - weakness in the present Chinese system of Emi- nent Domain. Besides the absence of effective constraints on the behaviors of takings, the administrative allocative mecha- nism of land resources may be the most important root of contentious events, so market - oriented reforms should be pushed further. Measures and policy for preventing the contentious events will be put out as follows: to acquire property by market mechanisms; to adopt a compensation requirement of more than fair market value; to eschew the intensive areas of subjective value or to forgive the plan of takings; to enforce strict mechanisms to constraint on the behaviors of takings.%近年来,由拆迁所引发的情绪事件时有发生。从行为经济学有关禀赋效应和财政幻觉的视角可以剖析由拆迁引发情绪事件的认知根源和制度基础,揭示我国拆迁中情绪事件的发生机制。对于财产拥有者而言,禀赋效应使其视“家宅如城堡”,它是个体的人格财产;对于财产征收者而言,财政幻觉使其视之为可用货币计价和任意替换的资产。对同一财产对象,两种不同的价值评价模式并存,这内在

    1980-01-01

    The NASA/Baltimore Applications Project operating at the Goddard Space Flight Center was called upon by the Housing Authority of Baltimore City to consider the problems of providing low cost public housing because of increased energy costs and suggest methods for correction and alleviation. The first step chosen was to elicit as many different options for solution as possible through means of a Public Housing Energy Workshop held in Easton, Md. in September 1980. A final role for the Workshop was a listing and qualifying of each alternative as to its suitability and cost. Specific areas were examined by three panels: (1) Systems, (2) Conservation and Motivation, and (3) Fuels. Each panel was made up of persons from differing but appropriate backgrounds; membership was not restricted to housing people alone. A summary of their deliberations is given - it will be used as a stepping stone to further selection and implementation of alternatives.

    Affordable housing is an important form of income security for low-income older persons. This article describes characteristics of older persons waitlisted for either public housing or a housing choice voucher (HCV; previously Section 8) in Portland, Oregon. 358 persons (32% response rate) completed a mailed survey with questions about demographics, health and housing status, food insecurity, and preference for housing with services. Findings indicate that many waitlisted older persons experienced homelessness or housing instability, poor health, high hospital use, and food insecurity. Public housing applicants were significantly more likely to report lower incomes, homelessness, and food insecurity than HCV applicants. We conclude with policy implications for housing and health agencies that serve low-income older persons.

    Full Text Available There is no consensus among researchers of what constitutes projects success; every project type may have different success criteria. Identifying project success criteria at the initial stage of a project can contribute to effective utilization of resources. The aim of this study is to establish the criteria for measuring public housing project success in Nigeria. The data collection was carried out in Nigeria by means of structured interviews with ten experts in housing, a pilot survey and questionnaire survey.  A questionnaire survey was carried out in which 550 questionnaires were administered to construction professionals who involve in public housing projects, in order to elicit their perceptions on success criteria for public housing projects. The sample was drawn using purposive sampling method since there is no sample frame of people with experience in public housing. Two hundred and seventy six questionnaires (276 were returned completed representing 50.2% response rate. The data collected were analysed using structural equation modelling technique. The results reveal six criteria for measuring public housing project management success, these are client’s satisfaction, project completed on time, project completed to specified quality standard, absence of disputes, safety, and completion within budget. The results also reveal four criteria for measuring public housing product success which include meeting the project purpose, end users’ satisfaction, environmental impact and aesthetic appearance of the . Understanding the findings of this study by policy makers and project managers can improve effectiveness and efficiency of public housing projects in Nigeria.

    2016-01-01

    This article draws on the concept of residential context of housing and its relationship to health. It considers a bundle of changes through implementation of a housing renewal initiative as part of the Carlton Housing Estate Upgrading Project in Melbourne, Australia. Beyond the quality and appropriateness of the housing, pertinent factors explored include social networks, safety and security, and green open space. Data collection for the research project included in-depth interviews with public housing tenants, private residents, and service providers who live on and service the estate, as well as neighborhood observations and participation in on-site events. A key finding was that the relational processes of how tenants were related to by others-specifically, the way housing was reallocated during the processes of renewal-affected social housing tenants' self-perceived health and well-being.

  13. Sense of place among Atlanta public housing residents.

    Tester, Griff; Ruel, Erin; Anderson, Angela; Reitzes, Donald C; Oakley, Deirdre

    2011-06-01

    For almost two decades now, cities around the country have been demolishing traditional public housing and relocating residents to subsidized private market rental housing. In this paper, we examine sense of place, consisting of both community and place attachment, among a sample of Atlanta public housing residents prior to relocation (N = 290). We find that 41% of the residents express place attachment, and a large percentage express some level of community attachment, though residents of senior public housing are far more attached than residents of family public housing. Positive neighborhood characteristics, such as collective efficacy and social support, are associated with community attachment, and social support is also associated with place attachment. Negative neighborhood characteristics, such as social disorder and fear of crime, are not consistently associated with sense of place. We argue that embodied in current public housing relocation initiatives is a real sense of loss among the residents. Policy makers may also want to consider the possibilities of drawing upon residents' sense of place as a resource for renovating and revitalizing public housing communities rather than continuing to demolish them and relocating residents to other neighborhoods.

    Full Text Available Chinese house prices have been receiving huge coverage in both the domestic and the international media. Although the Chinese government has implemented many policies to control house prices, especially in the big cities, it is obvious that there is disequilibrium between demand for and supply of houses. Even though numerous housing policies have been put in place to overcome that, house prices in China are still rising. Many Chinese citizens from the low- and middle-incomes group find it difficult to purchase a house in the cities due to high house prices. This paper covers the current situation of the house prices in China, introduces the existing state of affairs about the Chinese housing market, explores a series of important reasons for high house prices, examines various public policies the Chinese government is using to control real estate, as well as reveals the citizens’ perceptions related to rising house prices. To gauge citizens’ perception of the current state of affairs in this regard, a questionnaire survey was conducted to gather information with a final sample of 256 respondents from more than ten cities of different tiers in the different regions of China.

    Tooth loss in adults diminishes quality of daily life, affecting eating, speaking, appearance, and social interactions. Tooth loss is linked to severe periodontitis and caries; and to risk of stroke, cardiovascular disease, rheumatoid arthritis, and dementia. At the national (USA) level, poverty and African-American race have been linked to lower utilization of dental services, suggesting that the 7.5 million residents of publicly supported housing may be at risk of tooth loss and poor overall oral health. We assessed whether residence in publicly supported housing in Boston was associated with four oral health-related indicators. Compared to residents of nonpublicly supported housing, after adjusting for covariates residents of both public housing developments (PHDs) and rental assistance units (RAUs) had significantly lower odds of having had a dental cleaning in the past year (PHD, OR = 0.64 (95 % CI, 0.44-0.93); RAU, OR = 0.67 (95 % CI, 0.45-0.99))-despite parity in having had a past year dental visit. Further, residents of RAUs had double the odds of having had six or more teeth removed (OR = 2.20 (95 % CI, 1.39-3.50)). Associations of race/ethnicity and housing type with dental insurance were interrelated. Unadjusted results document a deficit in oral health-related indicators among public housing residents, taken as a group, giving a clear picture of an oral health care gap and identifying a defined real-world population that could benefit from services. Existing public housing infrastructure could provide both a venue and a foundation for interventions to reduce oral health disparities on a broad scale.

    Over one million HUD-supported public housing units provide rental housing for eligible low-income families across the country. A survey of over 100 public housing authorities (PHAs) across the country indicated that there is a high level of interest in developing low-cost solutions that improve energy efficiency and can be seamlessly included in the refurbishment process. Further, PHAs, have incentives (both internal and external) to reduce utility bills. ARIES worked with four PHAs to develop packages of energy efficiency retrofit measures the PHAs can cost-effectively implement with their own staffs in the normal course of housing operations at the time when units are refurbished between occupancies. The energy efficiency turnover protocols emphasized air infiltration reduction, duct sealing, and measures that improve equipment efficiency. ARIES documented implementation in 18 housing units. Reductions in average air leakage were 16% and duct leakage reductions averaged 23%. Total source energy consumption savings due to implemented measures was estimated at 3-10% based on BEopt modeling with a simple payback of 1.6 to 2.5 years. Implementation challenges were encountered mainly related to required operational changes and budgetary constraints. Nevertheless, simple measures can feasibly be accomplished by PHA staff at low or no cost. At typical housing unit turnover rates, these measures could impact hundreds of thousands of units per year nationally.

    More than 1 million HUD-supported public housing units provide rental housing for eligible low-income families across the country. A survey of over 100 public housing authorities (PHAs) across the country indicated that there is a high level of interest in developing low-cost solutions that improve energy efficiency and can be seamlessly included in the refurbishment process. Further, PHAs, have incentives (both internal and external) to reduce utility bills. ARIES worked with two PHAs to develop packages of energy efficiency retrofit measures the PHAs can cost effectively implement with their own staffs in the normal course of housing operations when units are refurbished between occupancies. The energy efficiency turnover protocols emphasized air infiltration reduction, duct sealing and measures that improve equipment efficiency. ARIES documented implementation 10 ten housing units. Total source energy consumption savings was estimated at 6%-10% based on BEopt modeling with a simple payback of 1.7 to 2.2 years. At typical housing unit turnover rates, these measures could impact hundreds of thousands of units per year nationally.

A survey of over 100 PHAs across the country indicated that there is a high level of interest in developing low cost solutions that improve energy efficiency and can be seamlessly included in the refurbishment process. Further, PHAs, have incentives (both internal and external) to reduce utility bills. ARIES worked with two public housing authorities (PHAs) to develop packages of energy efficiency retrofit measures the PHAs can cost effectively implement with their own staffs in the normal course of housing operations at the time when units are refurbished between occupancies. The energy efficiency turnover protocols emphasized air infiltration reduction, duct sealing and measures that improve equipment efficiency. ARIES documented implementation in ten housing units. Reductions in average air leakage were 16-20% and duct leakage reductions averaged 38%. Total source energy consumption savings was estimated at 6-10% based on BEopt modeling with a simple payback of 1.7 to 2.2 years. Implementation challenges were encountered mainly related to required operational changes and budgetary constraints.

  6. Banishment in Public Housing: Testing an Evolution of Broken Windows

    Full Text Available Banishment policies grant police the authority to formally ban individuals from entering public housing and arrest them for trespassing if they violate the ban. Despite its widespread use and the social consequences resulting from it, an empirical evaluation of the effectiveness of banishment has not been performed. Understanding banishment enforcement is an evolution of broken windows policing, this study explores how effective bans are at reducing crime in public housing. We analyze crime data, spanning the years 2001–2012, from six public housing communities and 13 surrounding communities in one southeastern U.S. city. Using Arellano-Bond dynamic panel models, we investigate whether or not issuing bans predicts reductions in property and violent crimes as well as increases in drug and trespass arrests in public housing. We find that this brand of broken windows policing does reduce crime, albeit relatively small reductions and only for property crime, while resulting in an increase in trespass arrests. Given our findings that these policies have only a modest impact on property crime, yet produce relatively larger increases in arrests for minor offenses in communities of color, and ultimately have no significant impact on violent crime, it will be important for police, communities, and policy makers to discuss whether the returns are worth the potential costs.

  10. Phantom Housing: The Rise and Fall of Public Housing in North America

    Directory of Open Access Journals (Sweden)

    2012-11-01

    Full Text Available This paper examines the rise and fall of public housing in North America in order to explore the principle of sustainability. By extension, it addresses the concept of sustainability as it relates to the city. Urbanity is simultaneously the most and least sustainable form of development. While extremely sustainable from the point of view of density (economies of scale, efficient use ofinfrastructure, etc., it is highly vulnerable to social, political and economic forces. Such forces can easily trump the environmental sustainability of any building or community.The death and transfiguration of key portions of our public housing stock provides insights into this phenomenon – for which I will use Toronto’s Regent Park as a case study. The redevelopment ofthis 69-acre parcel aims to transform a failed social vision into a model for sustainable community development.

  11. Public Attitudes to Housing Systems for Pregnant Pigs.

    Directory of Open Access Journals (Sweden)

    E B Ryan

    Full Text Available Understanding concerns about the welfare of farm animals is important for the development of socially sustainable production practices. This study used an online survey to test how views on group versus stall housing for pregnant sows varied when Canadian and US participants were provided information about these systems, including access to scientific papers, YouTube videos, Google images, and a frequently-asked-questions page (S1 Appendix. Initial responses and changes in responses after accessing the information were analyzed from Likert scores of 242 participants and from their written comments. Participants were less willing to accept the use of gestation stalls after viewing information on sow housing. For example, initially 30.4% of respondents indicated that they supported the use of gestation stalls; this declined to 17.8% after participants were provided additional information. Qualitative analysis of comments showed that supporters of gestation stalls expressed concern about the spread of disease and aggression between animals in less confined systems, whereas supporters of group housing placed more emphasis on the sow's ability to interact socially and perform natural behaviors. These results point to public opposition to the use of gestation stalls, and indicate that the more that the public learns about gestation stalls the less willing they will be to accept their use.

    Eziyi Offia Ibem

    2011-07-01

    Full Text Available This study investigated the contextual and organizational challenges in public housing provisions in Nigeria in the post independent era. The study was motivated by dearth of empirical studies on organizational challenges responsible for the inability of public housing provision to keep pace with urban housing demand in this country. Based on data derived from a survey of fifteen public housing agencies in southern Nigeria, the study found that scarcity of housing finance, lack of consistency and continuity in housing policy formulation and poor implementation strategies, unfavourable political environment and declining population of tradesmen in the construction industry were the contextual challenges in public housing provisions. In addition, lack of inter-agencies collaborations, poor staff remuneration and reward system as well as inadequate operational equipments and vehicles were found to be responsible for the inability of public housing agencies to deliver on their housing mandate. The paper suggests that stable polity, consistency in housing policies and programmes and capacity building in public housing agencies through public-private partnerships are needed to improve the quantity and quality of public housing in Nigeria.

  2. Cluster approach to the development of housing services and public utilities in the region

    Directory of Open Access Journals (Sweden)

    Sergey Ivanovich Bazhenov

    2012-03-01

    Full Text Available The ongoing crisis in the housing services and public utilities sphere determines the need to accelerate its integration into the market space. The author proposes to apply the cluster initiatives, which, in his opinion, provide the solution of housing services and public utilities problems in terms of their broader vision. This paper attempts to highlight the benefits of the cluster approach to the development of housing services and public utilities, and identifies the main provisions in the process of its implementation. The essence of the concept of «housing services and social cluster of the region» in terms of housing services and public utilities development is revealed, members of cluster unification are designated, its components are identified, the purpose of introducing the cluster model of housing services and public utilities reform management is determined, which essence is to change the mentality of the producers and consumers of housing services and public utilities in the direction of increasing responsibilities and respect for mutual interests in the market of housing services and public utilities. The main provisions and principles of formation of housing services and social cluster of the region are reviewed, as well as the characteristics and trends of its development. An authorial approach to the development of a strategy of forming a housing services and social cluster in the region in accordance with modern trends is presented. The leading role of several factors in establishing the basic prerequisites for sustainable operation of housing services and social cluster of the region is justified. These factors include governmental regulation of pricing and forms of support to small entrepreneurship development, creation of financial security system, development of public-private partnerships and implementation of innovative technologies. The role of non-governmental organizations and public associations in the formation of

    In a unique partnership, the Boston Public Health Commission, the Boston Housing Authority (BHA), Boston University School of Public Health, the Committee for Boston Public Housing, and the West Broadway Task Force (WBTF) led an Integrated Pest Management (IPM) intervention in Boston's public housing developments. Key to the success of the program was recruiting residents to participate. Residents who were trained as Community Health Advocates (CHAs) at the West Broadway Development in South Boston, Massachusetts, recruited over 300 homes to participate in the IPM intervention (out of 484 living units). This article describes the recruitment strategy and success from the perspective of CHAs at the West Broadway development.

  13. New Isues In Singapore Public Housing From Elderly Perspective: case study

    Directory of Open Access Journals (Sweden)

    Ruzica Bozovic Stamenovic

    2012-10-01

    Full Text Available This paper examines emerging issues regarding Singapore public housing. With over 80 % of rapidly ageing population living in public housing the elderly perspective is of paramount importance for future development. Following a brief introduction of Housing and Development Board HDB 2 model we are examining new ideas occurring in different scopes and scales, from apartment to urban environment level. Issues like ageing in place, dignity, salutogenesis, active and independent life, image and identification, and other themes pertinent to old age are revisited. Recent issues like high-rise/high-density, consumerism and branding suggest that the usual dogmatic approach to elderly in public housing could be converted to result in creative, affordable, profitable and integrative public housing design.

  14. Contested visions of American democracy: citizenship, public housing, and the international arena.

    Science.gov (United States)

    Argersinger, Jo Ann E

    2010-01-01

    This essay reexamines the history of public housing and the controversy it generated from the Great Depression to the Cold War. By recasting that history in the global arena, it demonstrates that the debate over public housing versus homeownership was also a debate over the meaning of American citizenship and democracy, pointing up starkly divergent notions about what was and was not American. Through an examination of national conflicts and neglected local struggles, this article further shows that the fight over public housing was far more meaningful and volatile than traditionally assumed. Both critics and advocates of public housing drew from international experiences and imagery in positioning the home as a constitutive feature of citizenship in American democracy. Fears of Bolshevism, fascism, and communism served to internationalize issues of race, space, and housing and together shaped the decision of whether a decent home was an American right or privilege.

  15. Housing, Urban Renewal and Socio-Spatial Integration. A Study on Rehabilitating the Former Socialistic Public Housing Areas in Beijing

    Directory of Open Access Journals (Sweden)

    Xiaoxi Hui

    2013-02-01

    Full Text Available The initiative of this study derived from my concern of two critical urban issues in China today: housing and urban renewal. In the recent two decades, the Chinese urban housing stock underwent a significant, if not extreme, transformation. From 1949 to 1998, the urban housing stock in China largely depended on the public sector, and a large amount of public housing areas were developed under the socialistic public housing system in Beijing and other Chinese cities. Yet in 1998, a radical housing reform stopped this housing system. Thus, most of the public housing stock was privatized and the urban housing provision was conferred to the market. The radical housing privatization and marketization did not really resolve but intensified the housing problem. Along with the high-speed urbanization, the alienated, capitalized and speculative housing stock caused a series of social and spatial problems. The Chinese government therefore attempted to reestablish the social housing system in 2007. However, the unbalanced structure of the Chinese urban housing stock has not been considerably optimized and the housing problem is still one of the most critical challenges in China.Based on the background of privatization, the former socialistic public housing areas in Beijing confront the ambiguity of their housing stock and the confusion of housing management. While they still accommodate the majority of urban residents and are identified by their good places, (social and programmatic mixed communities, vibrant local life, and diversified housing types, they are facing the serious challenges of physical deterioration and social decline. Therefore, urban renewal was thought as an effective solution seeking to improve the living conditions in those neighborhoods. Nevertheless, urban renewal in itself is also a controversial issue. In order to solve the housing problem, the large-scale urban renewal in Beijing started at the beginning of the 1990s. The radical

    Full Text Available In the modern economic conditions, the housing and communal sector is the most problematic as the executive authorities’ opinion and Russian population opinion. The reform aims are deprivatization of objects the industry, transfer it in temporary managed by private business. In such conditions, there is a need for a new or upgrade existing mechanism of management of sector housing and communal services economic entities. One of the elements of innovation management mechanism is controlling. The definitions of this category madу by Russian and foreign scientists are considered in the article. The author have been summarizes the theoretical principles, practical experience. The model of housing and communal services financial controlling is designed. It contains the following elements: goals, objectives, subjects, object, function, types. Each element was described in detail and classified by type. In addition, the external and internal factors affecting the construction of controlling system in economic entities of the industry of housing and communal services are designated and marked. The advantages of introducing a system of controlling the activities of organizations in the utilities are described. The authors have identified and described in detail the difficulties of controlling introduction in the economic agents of industries management system

    Although there is much evidence about the effects of particular housing conditions on health, less is known about the practices of public health inspectors (PHIs) in relation to minimizing or eliminating potential housing health risks. The purpose of this qualitative study was to illuminate the practices of PHIs in relation to types of biological and physical housing risks. This study used photo vignettes to focus on PHIs' perceptions, options, and resultant interventions with regards to typical housing risks encountered by PHIs in northeastern Ontario. The vignettes represented two general categories of potential housing risks: biological exposures, and physical characteristics of housing. During a semi-structured interview, 34 PHI participants viewed the vignettes, assessed the housing hazard depicted in each, and described the most appropriate intervention. Traditional content analysis methods were used. The assessment of the physical housing hazards was fairly consistent among the PHIs. There seemed to be more variation in their assessment of risk associated with biological factors. Variation in responses was often explained by their different interpretations of the scope of the provincial legislation as well as local public health unit policies and practices. This study demonstrated that PHIs' assessment and responses to potential physical housing hazards were influenced by an interplay between variables related to residents, local service partners, organizational culture, and policy. The recommendations for action also range from specific public health unit protocol to broader research and policy advocacy initiatives. Collectively, the recommendations focus on strategies for optimizing the role of PHIs in reducing housing health risks in mid-size urban or rural areas.

    This study sought to examine whether: (1) the health composition of the social networks of children living in subsidized housing within market rate developments (among higher-income neighbors) differs from the social network composition of children living in public housing developments (among lower-income neighbors); and (2) children's social network composition is associated with children's own health. We found no significant differences in the health characteristics of the social networks of children living in these different types of public housing. However, social network composition was significantly associated with several aspects of children's own health, suggesting the potential importance of social networks for the health of vulnerable populations.

    Triatoma dimidiata is one of the primary vectors of Chagas disease. We previously documented the spatio-temporal infestation of houses by this species in the Yucatan peninsula, Mexico, and found that non-domiciliated triatomines were specifically attracted to houses. However, the factors mediating this attraction remained unclear. Artificial light has been known for a long time to attract many insect species, and therefore may contribute to the spread of different vector-borne diseases. Also, based on the collection of different species of triatomines with light traps, several authors have suggested that light might attract triatomines to houses, but the role of artificial light in house infestation has never been clearly demonstrated and quantified. Here we performed a spatial analysis of house infestation pattern by T. dimidiata in relation to the distribution of artificial light sources in three different villages from the Yucatan peninsula, Mexico. In all three villages, infested houses were significantly closer to public street light sources than non-infested houses (18.0 ± 0.6 vs 22.6 ± 0.4 m), and street lights rather than domestic lights were associated with house infestation. Accordingly, houses closer to a public street lights were 1.64 times more likely to be infested than houses further away (OR, CI95% 1.23-2.18). Behavioral experiments using a dual-choice chamber further confirmed that adult male and females were attracted to white light during their nocturnal activity. Attraction was also dependent on light color and decreased with increasing wavelength. While public lighting is usually associated with increased development, these data clearly show that it also directly contributes to house infestation by non-domiciliated T. dimidiata.

  19. 1999-2002 Public Housing Partnership: U.S. Department of Housing and Urban Development and U.S. Department of Energy

    Energy Technology Data Exchange (ETDEWEB)

    Ternes, M.P.

    2003-06-18

    In December 1999, the U.S. Department of Housing and Urban Development (HUD) entered into an Interagency Agreement (IAA) with the U.S. Department of Energy (DOE) and its Rebuild America Program to promote conservation and reduce utility costs in public housing through forums, research, demonstration, and evaluation. The IAA was effectively implemented from November 2000 to December 2002. Under the IAA, Rebuild America established 31 new partnerships with public housing authorities, started 6 new partnerships with organizations that focus on public housing, and initiated new projects with 6 existing Rebuild America public housing partnerships. These 43 partnerships directly involved 51 public housing authorities in 77 energy-related projects (several of the 43 partnerships involved multiple housing authorities and projects). Rebuild America assistance on these projects encompassed a wide range of activities, including planning assistance on energy management and capital investment, reviews of utility consumption and metering options, assistance in implementing HUD's energy incentives, design reviews and energy analyses, and assistance in the development of energy projects and resident programs. In addition, Rebuild America made presentations to housing authorities on energy efficiency opportunities and solutions and provided energy training on selected topics at 23 conferences and workshops that impacted many more housing authorities. This report provides an overview of the accomplishments achieved under the IAA; describes the 77 projects that have been completed, are under way, or are planned; and summarizes the presentations and training provided.

  20. Final report on implementation of energy conservation practices training in selected public housing developments

    1991-10-01

    This report on the implementation of energy conservation practices training in selected public housing developments represents an initiative of the Research and Education Division, Office of Minority Economic Impact, US Department of Energy. The Office of Minority Economic Impact (MI) was created by Congress in 1979, within the US Department of Energy, to afford the Secretary advice on the effect policies, regulations and other actions of DOE respecting minority participation in energy programs. The Director of MI is responsible for the conduct of ongoing research into the effects, including socio-economic and environmental, of national energy programs, policies, and regulations of the Department of minorities. Public housing in the United States is dominated by minorities, public housing is a large consumer of residential energy. Consequently, this project is a logical merging of these two factors and an attempt to somehow influence energy savings through improving public housing residents` energy-consumption practices. This final report attempts to capture the results of this current demonstration, and incorporate the historical basis for today`s results by renewing the efforts that preceded the implementation of energy conservation practices training in selected public housing developments.

    2015-12-01

    The study examines the effects of ethnic clusters and independent living arrangements on adaptation of elderly immigrants from the Former Soviet Union. The multigenerational living arrangements were compared with independent living in a dispersed ethnic community and in an ethnic cluster of public housing. The residents of the ethnic clusters of public housing reported poorer health, were more reliant on government resources, and experienced greater acculturative hassles. However, public housing residents reported significantly larger Russian-speaking and American social networks, greater American acculturation, higher social support from neighbors, as well as lower cultural alienation. In contrast, the multigenerational living arrangements were related to greater social support from extended family and higher extended family satisfaction. While, the independent living in the dispersed ethnic community was associated with smaller American social networks and higher levels of cultural alienation. The results highlight how the ecologies of different living arrangements are reflected in the nature of acculturative, social, and psychological experiences of elderly immigrants.

  5. Construction and demolition waste indicators.

    The construction industry is one of the biggest and most active sectors of the European Union (EU), consuming more raw materials and energy than any other economic activity. Furthermore, construction waste is the commonest waste produced in the EU. Current EU legislation sets out to implement construction and demolition waste (CDW) prevention and recycling measures. However it lacks tools to accelerate the development of a sector as bound by tradition as the building industry. The main objective of the present study was to determine indicators to estimate the amount of CDW generated on site both globally and by waste stream. CDW generation was estimated for six specific sectors: new residential construction, new non-residential construction, residential demolition, non-residential demolition, residential refurbishment, and non-residential refurbishment. The data needed to develop the indicators was collected through an exhaustive survey of previous international studies. The indicators determined suggest that the average composition of waste generated on site is mostly concrete and ceramic materials. Specifically for new residential and new non-residential construction the production of concrete waste in buildings with a reinforced concrete structure lies between 17.8 and 32.9 kg m(-2) and between 18.3 and 40.1 kg m(-2), respectively. For the residential and non-residential demolition sectors the production of this waste stream in buildings with a reinforced concrete structure varies from 492 to 840 kg m(-2) and from 401 to 768 kg/m(-2), respectively. For the residential and non-residential refurbishment sectors the production of concrete waste in buildings lies between 18.9 and 45.9 kg/m(-2) and between 18.9 and 191.2 kg/m(-2), respectively.

  6. Reconceptualizing the “Publicness” of Public Housing: The Case of Brussels

    Directory of Open Access Journals (Sweden)

    Nele Aernouts

    2015-04-01

    Full Text Available This article brings together various spatial and political theorizations on the commons as a broader project to understand multiple dimensions of the inclusive nature of public housing. By picking up theorizations on the commons, the article feeds the debate on the loss of “publicness” of public housing and removes attention from what is seen as a state related business. Four core-dimensions are identified: ownership, participation, community activity and physical configuration. The article takes a sample of public housing estates in the Brussels capital region as case studies to test the capacity of this framework to detect the degree of “publicness” of various forms of public housing. The preliminary results—based on this limited sample of cases studied through interviews with privileged informers and a literature study—suggest that approaches where individual households are actively involved in the organization of the dwelling environment work best to compensate for the loss of “publicness” that has occurred since the decline of the welfare state. In that respect, these approaches tie in with some early predecessors of “public” housing, mainly cooperatively organized garden city developments. Further in-depth case study research should shed more light on the validity of this hypothesis, as well as on the precise mechanisms and features that determine this regained “publicness”.

  7. Community-scale solar photovoltaics: housing and public development examples

    2008-03-15

    This report for the International Energy Agency (IEA) made by Task 10 of the Photovoltaic Power Systems (PVPS) programme takes a look at community-scale photovoltaics. The mission of the Photovoltaic Power Systems Programme is to enhance the international collaboration efforts which accelerate the development and deployment of photovoltaic solar energy. The aim of Task 10 is stated as being to enhance the opportunities for wide-scale, solution-oriented application of photovoltaics in the urban environment. This report provides examples of housing developments and incorporated townships that have integrated multiple stakeholder values into business solutions. The authors are of the opinion that builders, developers, architects and engineers need to consider orientation, aesthetics, load diversity, energy efficiency, grid infrastructure and end use. Residential and commercial building owners or occupants need to consider the design of electric services relative to loads, green image, and economic opportunities such as feed-in tariffs. Local government should give preference to granting permission to high-performance building projects. It is suggested that the finance and insurance sector consider the operational savings in overall debt allowances. System manufacturers and integrators should develop standardised systems. In the emerging PV community market, utilities are quickly gaining awareness of business opportunities. The need for professionals and skilled labour is quoted as having grown as drastically as the PV market itself.

    The historic Jewish Purification House Bet Tahara was erected in Olsztyn in 1913 on the basis of the debut design of Erich Mendelsohn, a world-famous architect born in Olsztyn. The most valuable element of the building is a self-supporting pyramid vault above a mourning hall. The paper presents the interesting structure of the building, its technical condition before renovation, as well as the scope of work involved in adapting it into a public utility building - MENDELSOHN HOUSE Intercultural Dialogue Centre. The undertaking was executed thanks to the commitment of the building's leaseholder - "Borussia" Cultural Community Association, which raised money for this goal from public funds.

  10. Families, Friends, and the Neighborhood of Older Adults: Evidence from Public Housing in Singapore

    Directory of Open Access Journals (Sweden)

    Treena Wu

    2012-01-01

    Full Text Available Introduction. This empirical paper examines how the Housing Development Board (HDB public housing neighborhood influences older urban Singaporeans' social interactions and ameliorates social isolation. Methods. Using 4,542 observations of noninstitutionalized urban adults aged 60 and above, ordered logistic regressions are run to determine the predictors of isolation while controlling for physical health and demographics. Results. 87% of older Singaporeans reside in public housing apartments while 13% reside in private market housing. The main predictor of social isolation is living alone and the second main predictor is coresidence with adult children. The relationship between coresidence with adult children and isolation is mediated when controlling for older adult functional limitations. The public apartment neighborhood and daily participation in public neighborhood events have substantial effects on reducing the risk of isolation. Older adult contact with friends alleviates isolation more than contact with non-coresiding relatives. Conclusion. Findings suggest that the public neighborhood-built environment in Singapore plays a positive role in the social interactions of the elderly. Knowledge of the factors that decrease the risk of social isolation will have implications for studying morbidity and mortality among the elderly.

  19. Global city aspirations, graduated citizenship and public housing: analysing the consumer citizenships of neoliberalism

    Directory of Open Access Journals (Sweden)

    Dallas Rogers

    2014-01-01

    Full Text Available Global city discourses rearticulate the relationships between the state, urban space and the global economy. At the local level, global city reconfigurations stamp the mark of a global economic order onto local citizenship practices. Public housing is a legacy of specific national (welfare states where citizenship rights arose from territorially bound constitutional discourses, and is incompatible in its current form with the consumer-based rights and responsibilities of a global economic order. At the same time, property markets in high-value areas of cities like Sydney, Australia, see not only increasing presence of international investment but fundamental changes in planning and governance processes in order to facilitate it. Global market-oriented discourses of urban governance promote consumer “performances of citizenship” and a graduated approach to the distribution of rights, including the right to housing. In this article we explore what is new about neoliberal approaches to public and social housing policy, and how public tenants respond to and negotiate it. In Australia tenants’ right to participate in local-level democracy, and in housing management, must be reconsidered in light of the broader discourses of consumer citizenship that are now enforced on tenants as a set of “responsibilities” to the market and state.

  20. Does demolition or refurbishment of old and inefficient homes help to increase our environmental, social and economic viability?

    Power, Anne [London School of Economics, Houghton Street, London WC2A 2AE (United Kingdom); Sustainable Development Commission, Room 101, 55 Whitehall, c/o 3-8 Whitehall Place, London SW1A 2HH (United Kingdom)

    2008-12-15

    The issue of whether to demolish or refurbish older housing has been debated for over a century. It has been an active policy area since the late 1880s, when the Government first authorised the statutory demolition of insanitary slums. In the 1960s, revulsion at the scale of 'demolition blight' and new building caused a rethink, leading to a major reinvestment in inner city neighbourhoods of older housing. In the past 5 years, debate on demolition and new building has been intensified by the Government's Sustainable Communities Plan of 2003, with its proposals for large-scale clearance and building. Environmental arguments about renovating the existing stock have gained increasing prominence as people have sought to defend their communities from demolition. The evidence on whether demolition would reduce the amount of greenhouse gases we emit into the atmosphere is unclear and disputed. This paper summarises the evidence and arguments, and attempts to clarify the most realistic, achievable route to major reductions in energy use in homes. The arguments that apply to housing also apply to most other buildings and therefore to the overall built environment, which accounts for half of all carbon emissions. Three main sources of evidence have helped in the development of this paper, but there are many other studies we draw on in the discussion.

  1. The role of public spaces in creating place attachment (example of Zacisze, Warsaw housing estate

    Directory of Open Access Journals (Sweden)

    Mantey Dorota

    2015-09-01

    Full Text Available This article raises the question of place attachment in the context of an increasingly important factor, that is the use of gathering and leisure places. The author publishes findings of a survey conducted among the residents of Zacisze, Warsaw, a detached housing estate with a very poor range of public places for gathering and leisure. The study has proved that the use of local public spaces, as a specific category of place, reinforces attachment to the whole housing estate. The study also confirms the important role that social factors have in building place attachment. Conditions already exist for considering social factors more important than physical ones in building a positive relationship with a territory.

  2. The role of the public sector in the provision of housing supply in Turkey, 1950–2009.

    Özdemir, Dilek

    2011-01-01

    This study examines the changing role of the public sector in Turkey with regard to housing provision since 1950, and particularly since 2000, and seeks to clarify how public intervention has affected housing provision and urban development dynamics in major cities. Three periods may be identified, with central government acting as a regulator in a first period characterized by a ‘housing boom’. During the second period, from 1980 to 2000, a new mass housing law spurred construction activity, although the main beneficiaries of the housing fund tended to be the middle classes. After 2000, contrary to emerging trends in both Northern and Southern European countries, the public sector in Turkey became actively involved in housing provision. During this process, new housing estates were created on greenfield sites on the outskirts of cities, instead of efforts being made to rehabilitate, restore or renew existing housing stock in the cities. Meanwhile, the concept of ‘urban regeneration’ has been opportunistically incorporated into the planning agenda of the public sector, and — under the pretext of regenerating squatter housing areas — existing residents have been moved out, while channels for community participation have been bypassed.

    Multi-unit housing environments remain significant sources of secondhand smoke (SHS) exposure, especially for vulnerable populations in subsidized housing. In Philadelphia, the largest US housing authority to implement smoke-free policies, we measured baseline resident smoking-related behaviors and attitudes, and longitudinal exposures to airborne nicotine, during policy development and implementation. In 4 communities, we collected data in 2013, 2014, and 2016, before and after introduction of comprehensive smoke-free policies, interviewing persons in 172 households, and monitoring air-borne nicotine in non-smoking homes and public areas. Average nicotine level differences across years were estimated with multi-level models. Fifty-six percent of respondents smoked. Only 37% of households were smoke-free, with another 41% restricting smoking by area or time of day. The number of locations with detectable nicotine did not differ before and after policy implementation, with approximately 20% of non-smoking homes and 70%-80% of public areas having detectable nicotine. However, public area nicotine levels were lower in 2016, after policy implementation, than in 2013 and 2014 (-0.19 μg/m(3), p = .03). Findings suggest that initial policy implementation was associated with reduced SHS exposure in Philadelphia. As HUD strengthens smoke-free policies, SHS monitoring can be useful to educate stakeholders and build support for policy enforcement.

  7. Social mixing through densification? The struggle over the Little Mountain public housing complex in Vancouver

    Directory of Open Access Journals (Sweden)

    Rosol, Marit

    2015-09-01

    Full Text Available In times of peak-oil and the on-going ‘urban renaissance’ (Porter and Shaw 2009, urban densification becomes increasingly more important. Densification is promoted not only for environmental reasons – in the sense of developing more compact and thus more sustainable cities – but also, as is the case in Vancouver, in the name of ‘social mixing’. Taking the conflict over “Little Mountain” – the oldest public housing complex in the province of British Columbia, Canada – as example, the article shows the conflicts that can arise in the process of densification. Despite the protests of residents and their supporters and without any concrete plans for redevelopment, almost all of the once 224 social housing units were demolished in 2009 to make room for at least 1,400 market condos (besides the 1-for-1 replacement of the social units. The example shows that densification processes that lack social measures for securing tenure for long-time residents lead to the displacement of poorer people, and to increased socio-spatial disparities. Furthermore, densification will not alleviate the affordability crisis but intensify it, if all the additionally created housing units will be market-housing only. Based on this example, the article shows that a purported social-mix policy is mainly motivated by recapturing prime real-estate, and identifies the rhetoric of ‘social mixing’ as ‘gentrification by stealth’ (Bridge et al. 2012.

    Low-income and minority groups in the United States have low levels of physical activity that contribute to health inequities. In public housing communities, both built and social environments are key factors that impact residents' physical activity levels. To develop and evaluate women-only physical activity programs that provide women from cultures in which physical activity in mixed-gender settings is not acceptable (e.g., Muslim women) with physical activity opportunities. We describe the use of community-based participatory research (CBPR) process and evaluation feedback from our initial research and evaluation phases, including focus groups, to shape interventions. Active community engagement in all phases of research, including cultural tailoring of interventions, and decisions about location and affordability, was critical. Implementing interventions in public housing is feasible, but requires frequent feedback from residents and correction. The use of CBPR resulted in the implementation of a successful, culturally appropriate set of physical activity interventions, specifically for Muslim Somali women. Housing authorities should consider incorporating recreational facilities on site and women-only opportunities to provide venues for physical activity.

  13. Efficiency of Introduction of Innovation Energy Saving Equipment at Ukrainian Housing and Public Utilities

    2014-03-01

    Full Text Available The article considers application of innovation energy saving equipment for energy housing and public utilities of Ukraine, namely – use of economiser-utiliser made of flat oval tubes with partial cross finning. The goal of the article is justification of efficiency of use of the economiser-utiliser, heat-exchange surfaces of which are made of packs of flat oval tubes with partial cross finning. The article shows economic efficiency of use of the economiser-utiliser for heat supply for tenement houses of the city of Dnipropetrovsk. It shows annual saving of natural gas from application of energy saving equipment and its pay-back period in housing and public utilities of Ukraine. Introduction of heat utilisers with efficient heat-transfer elements of principally new geometry and design is caused by the fact that it allows enterprises to reduce general costs of production by means of saving natural gas, increase of the ratio of fuel heat use and, thus, reduction of cost value of heat production.

  14. Context, built form and space: A case of public housing estates in Hong Kong

    2012-06-01

    Full Text Available The context of public housing development in Hong Kong can be traced back to a deep rooted history when it was a need rather than a choice. At present, the public housing estates have become a much desired residential destination by the general people of Hong Kong although several changes in design have been observed that are not completely adapted by the residents. This study aims to investigate on the changing phenomenon of the context and the built form; and its impact on space in terms of adaptability by the residents. It has been found that, forced or formal communal spaces influenced by self-conscious culture discourage social interaction where quantitative measures are only applied, and informal communal spaces encouraged by unselfconscious culture bring happy social life. Contemporary built forms in the housing estates have changed a lot both externally and internally, and attention has been given to quantitative measures and formal spatial arrangements. As a result a gap is emerging between context, built form and adapted use of space. Therefore, measures such as qualitative approach, sensitively designed spatial arrangements are recommended to minimize the gap.

  15. Measure Guideline. Five Steps to Implement the Public Housing Authority Energy-Efficient Unit Turnover Checklist

    2015-07-09

    Five Steps to Implementing the PHA Energy Efficient Unit Turnover Package (ARIES, 2014) is a guide to prepare for the installation of energy efficient measures during a typical public housing authority unit turnover. While a PHA is cleaning, painting and readying a unit for a new resident, there is an opportunity to incorporate energy efficiency measures to further improve the unit's performance. The measures on the list are simple enough to be implemented by in-house maintenance personnel, inexpensive enough to be folded into operating expenses without needing capital budget, and fast enough to implement without substantially changing the number of days between occupancies, a critical factor for organizations where the demand for dwelling units far outweighs the supply. The following guide lays out a five step plan to implement the EE Unit Turnover Package in your PHA, from an initial Self-Assessment through to Package Implementation.

  16. Turning a Blind Eye: Public Support of Emergency Housing Policies for Sex Offenders.

    Socia, Kelly M; Dum, Christopher P; Rydberg, Jason

    2017-07-01

    In this study, we examine the influences of citizen decision making in the context of four policy scenarios that would affect the living conditions of sex offenders (SOs) residing at an "emergency shelter" budget motel. We surveyed 773 citizens in an online survey about their support for four policy scenarios that would improve the living conditions of SOs: (a) at no cost to the respondent, (b) in exchange for a US$100 tax increase, and (c) by relocating SOs within the respondent's neighborhood (i.e., "in my backyard"/IMBY scenario). The fourth scenario involved moving nearby SOs into substandard housing located far away from the respondent (i.e., "not in my backyard"/NIMBY). While prior research finds that the public overwhelmingly supports punitive SO policies, we find that indifference is a mainstay of public opinion about improving SO housing conditions. That is, we find only modest levels of average support for any of the policy scenarios, and policy support decreased when increased taxes would be involved, compared with a "no cost" scenario. While no respondent characteristics significantly predicted policy support consistently across all four scenarios, some scenarios showed stark differences in support when considering specific respondent characteristics. Overall, these results suggest that what does affect support depends on the details of the policy being proposed, as well as who is considering the policy. We end by discussing the policy implications of our study for both policymakers and the public.

  17. Management of Diversity in the Delivery of Public Services. A Reflection from the Policies of Housing in Andalusia

    Directory of Open Access Journals (Sweden)

    Manuela A. Fernández-Borrero

    2015-03-01

    Full Text Available Based on the management of diversity’s implications on the provision of public services, this work reflects on the perception that groups with ethnic differentiation have over housing policies in Andalusia. Specifically, we present the results obtained through a questionnaire elaborated ad hoc from a project based on modeling socio-spatial social intervention in social housing in Andalusia. The most significant differences found in relation to the Andalusians who benefit from these politics are exposed, with differentiation of the Gypsy collective as well as the Group of Moroccan immigrants who have access to this type of housing. Despite the differences, the needs for action in the field of social housing are equal for everyone in the neighborhood, despite ethnic diversity, although their perceptions, valuations and satisfaction can influence actions that are developed and must be considered. Finally, we believe that the politics of public housing in Andalusia expires with the social function of the housing. The problems reside in improving the management of this public park to achieve a major implication of the tenants in the maintenance of the communities and to promote new public housings that they could answer to the situations supervened in this context of crisis.

  20. Estimates of Refrigerator Loads in Public Housing Based on Metered Consumption Data

    Energy Technology Data Exchange (ETDEWEB)

    Miller, JD; Pratt, RG

    1998-09-11

    The New York Power Authority (NYPA), the New York City Housing Authority (NYCHA), and the U.S. Departments of Housing and Urban Development (HUD) and Energy (DOE) have joined in a project to replace refrigerators in New York City public housing with new, highly energy-efficient models. This project laid the ground work for the Consortium for Energy Efficiency (CEE) and DOE to enable housing authorities throughout the United States to bulk-purchase energy-efficient appliances. DOE helped develop and plan the program through the ENERGY STAR@ Partnerships program conducted by its Pacific Nofiwest National Laboratory (PNNL). PNNL was subsequently asked to conduct the savings evahations for 1996 and 1997. PNNL designed the metering protocol and occupant survey, supplied and calibrated the metering equipment, and managed and analyzed the data. The 1996 metering study of refrigerator energy usage in New York City public housing (Pratt and Miller 1997) established the need and justification for a regression-model-based approach to an energy savings estimate. The need originated in logistical difficulties associated with sampling the population and pen?orming a stratified analysis. Commonly, refrigerators[a) with high representation in the population were missed in the sampling schedule, leaving significant holes in the sample and difficulties for the stratified anrdysis. The just{jfcation was found in the fact that strata (distinct groups of identical refrigerators) were not statistically distinct in terms of their label ratio (ratio of metered consumption to label rating). This finding suggested a general regression model could be used to represent the consumption of all refrigerators in the population. In 1996 a simple two-coefficient regression model, a function of only the refrigerator label rating, was developed and used to represent the existing population of refrigerators. A key concept used in the 1997 study grew from findings in a small number of apartments

    African American adolescents are disproportionately represented in urban public housing developments. These neighborhoods are generally characterized by high rates of poverty, crime, violence, and disorganization. Although evidence is emerging on youths in these communities, little is known about their depressive symptoms, perceived efficacy, or frequency of substance use and sex-risk behavior. Further, even less is known about their exposure to community and household violence, their parents' behavior, or their sense of connection to their communities. Using a sample of 782 African American adolescents living in public housing neighborhoods located in four large U.S. cities, this article attempts to rectify the observed gap in knowledge by presenting a descriptive overview of their self-reported depressive symptoms; self-efficacy; frequencies of delinquent and sexual-risk behavior; and alcohol, tobacco, and other drug use. The self-reported ratings of their parents' behavior as well as their exposure to community and household violence are presented. Analytic procedures include descriptive statistics and mean comparisons between genders and across research cities. Results suggest several differences between genders and across research sites. However, results are not very different from national data. Implications for social work practice are discussed.

    2010-01-01

    Full Text Available Problem statement: Debris from construction or demolition/deconstruction processes have no significant impact on the environment as they are res-usable and inert. This has been also long admitted for solid waste generated by the demolition of damaged cities following violent earthquakes. Approach: This study is a contribution to the assessment of actual impact on the quality of groundwater of buried demolition debris from the city of Boumerdes, in the North of Algeria 5 years after the May 21st 2003 earthquake hit the region. The public discharge of Boumerdes city has been used as a temporary landfill. It is located about 5 km downtown of Boumerdes at the Tidjelabine site which is marly-calcareous formation. Leachate from the landfill was directly rejected in the receiving environment, where the soil is marly-calcareous type with cracks giving a variable permeability (10-2 m sec-1 to nearly 10-6 m sec-1 that facilitates infiltration of potential pollutants to the groundwater. The slope character (from 5-10% of the field contributes to pollutants movement and may accentuate water quality deterioration. Three domestic wells (designated S1, S2 and S3 were selected in the vicinity of the landfill and served as piezometers. Leachate samples were taken from the landfill and evaluated. Results: Leachate analysis indicated organic matter with relatively high COD (1136 mg L-1 O2 and BOD5 (200 mg L-1 O2; whereas the pH yielded 7.65 thus indicating fermentation phase of the landfill. Heavy metal contents were beyond national standard limits except for Pb with 0.51 mg L-1 which is slightly higher than limit value of 0.5 mg L-1. More than five years after the creation of this landfill and despite its predominant C&D nature, these results showed that it was following a typical urban wastes decomposition scheme. Same analysis carried on water samples drawn from the piezometers yielded following results: acidic pH (6.88, acceptable values of target heavy metals

  6. Project to design and develop an energy-related program: For public housing residents and renters: Volume 1, Final report

    Energy Technology Data Exchange (ETDEWEB)

    1988-05-01

    This demonstration project was undertaken as a result of an unsolicited proposal submitted by THE ASSIGNMENT GROUP (TAG) to the Office of Minority Economic Impact, Department of Energy (DOE). The problem to which the proposal responded was how to minimize the costs associated with public housing tenants in standard public housing as well as under homeownership transfers. A related problem was how to graduate the tenants to another level of responsibility and self-sufficiency through resident business developments and training in energy-related fields. The size and gravity of the problem necessitated a purpose or aim that had nationwide application, yet lent itself to a microscopic look. Consequently, the goal that emanated was the design and development of an energy-related demonstration program that educates public housing residents, facilitates indigenous business development where appropriate, and trains residents to provide needed services.

    2016-01-01

    This paper assesses how and/or whether household and community factors are associated with self-reported food security among young people living in public housing (N=151). Results suggest that food security was negatively related to age, particularly to older youth. Also, household size-have many people in the household, household hardships, and household conflict were negatively related to food security. On the contrary, food security was positively related to community cohesion and the presence of the extended family within the public housing neighborhood. Findings seem to suggest that non-specialty food previsions (e.g., community cohesion and family networks) may be important in understanding food security among families living in public housing. A number of program and policy implications are presented.

    Knowledge of stroke symptoms is associated with seeking medical attention early, and knowledge of risk factors is an essential factor in stroke prevention. In this study, we evaluated the level of stroke literacy in Singapore. A cross-sectional study of Singapore citizens and permanent residents aged 21 years and above was conducted in a public housing estate. Participants were randomly sampled using multi-stage stratified sampling. Assessment of awareness of stroke symptoms and risk factors was performed using open-ended questions. In total, 687 respondents were recruited, with a response rate of 69.7%. Overall, 52.4% of respondents identified the brain as the source of pathology, and 47.6% could cite at least 1 of the 3 FAST symptoms (facial droop, arm weakness and speech difficulty), while 40% could name 2 or more of 7 established risk factors for stroke (high blood pressure, high cholesterol, cigarette smoking, diabetes mellitus, older age, previous heart attacks and stroke). Respondents at higher risk of stroke (older individuals and those with stroke risk factors) did not have greater awareness of stroke symptoms and risk factors. The majority of respondents reported they would seek immediate medical care if they experienced stroke symptoms. Only 59.4% knew the emergency ambulance service telephone number. In a sample of Singaporean adults residing in a public housing estate, we found evidence of poor stroke literacy, highlighting the need for comprehensive population-based education efforts. There is a role for opportunistic education among those at higher risk of stroke.

  9. Use of rubble from building demolition in mortars.

    2002-01-01

    Because of increasing waste production and public concerns about the environment, it is desirable to recycle materials from building demolition. If suitably selected, ground, cleaned and sieved in appropriate industrial crushing plants, these materials can be profitably used in concrete. Nevertheless, the presence of masonry instead of concrete rubble is particularly detrimental to the mechanical performance and durability of recycled-aggregate concrete and the same negative effect is detectable when natural sand is replaced by fine recycled aggregate fraction. An alternative use of both masonry rubble and fine recycled material fraction could be in mortars. These could contain either recycled instead of natural sand or powder obtained by bricks crushing as partial cement substitution. In particular, attention is focused on the modification that takes place when either polypropylene or stainless steel fibers are added to these mortars. Polypropylene fibers are added in order to reduce shrinkage of mortars, stainless steel fibers for improving their flexural strength. The combined use of polypropylene fibers and fine recycled material from building demolition could allow the preparation of mortars showing good performance, in particular when coupled with bricks. Furthermore, the combined use of stainless steel fibers and mortars containing brick powder seems to be an effective way to guarantee a high flexural strength.

    The Kentucky Geological Survey (KGS) completed a second phase of carbon dioxide (CO{sub 2}) injection and seismic imaging in the Knox Group, a Cambrian Ordovician dolomite and sandstone sequence in September 2010. This work completed 2 years of activity at the KGS No. 1 Marvin Blan well in Hancock County, Kentucky. The well was drilled in 2009 by a consortium of State and industry partners (Kentucky Consortium for Carbon Storage). An initial phase of CO{sub 2} injection occurred immediately after completion of the well in 2009. The second phase of injection and seismic work was completed in September 2010 as part of a U.S. DOE funded project, after which the Blan well was plugged and abandoned. Following completion of research at the Blan well, a final public meeting and open house was held in Hancock County on October 28, 2010. This meeting followed one public meeting held prior to drilling of the well, and two on site visits during drilling (one for news media, and one for school teachers). The goal of the final public meeting was to present the results of the project to the public, answer questions, and address any concerns. Despite diligent efforts to publicize the final meeting, it was poorly attended by the general public. Several local county officials and members of the news media attended, but only one person from the general public showed up. We attribute the lack of interest in the results of the project to several factors. First, the project went as planned, with no problems or incidents that affected the local residents. The fact that KGS fulfilled the promises it made at the beginning of the project satisfied residents, and they felt no need to attend the meeting. Second, Hancock County is largely rural, and the technical details of carbon sequestration were not of interest to many people. The county officials attending were an exception; they clearly realized the importance of the project in future economic development for the county.

The county officials attending were an exception; they clearly realized the importance of the project in future economic development for the county.

  15. Architecture and the Ideology of Productivity: Four Public Housing Projects by Groupe Structures in Brussels (1950-65

    Directory of Open Access Journals (Sweden)

    Sven Sterken

    2014-08-01

    Full Text Available The field of public housing in Belgium formed the backdrop for two crucial phenomena in the shaping of the welfare state: first, the general compartmentalization along ideological lines of all aspects of society, including housing policy and town planning; second, the adaptation of the nation’s industry, and the building trade in particular, to postwar economic conditions. In the study of welfare state housing policies in Belgium, the latter aspect has so far been overlooked. This paper therefore proposes to look into a couple of public housing projects by Groupe Structures, the largest architectural firm in the country in the postwar period. As it will be argued, the stylistic and typological evolution of these schemes reveals the growing impact of a ‘productivist ideology’ on public housing in the 1950s. Paralyzed by the steeply rising building costs, the central buzzwords became standardization, industrialization and prefabrication. However, as the paper argues, the productivity doctrine failed to live up to its expectations as the sector’s turnover remained too marginal to put sufficient pressure on the construction industry.

  16. Validity of Self-Reported Tobacco Smoke Exposure among Non-Smoking Adult Public Housing Residents.

    Directory of Open Access Journals (Sweden)

    Shona C Fang

    Full Text Available Tobacco smoke exposure (TSE in public multi-unit housing (MUH is of concern. However, the validity of self-reports for determining TSE among non-smoking residents in such housing is unclear.We analyzed data from 285 non-smoking public MUH residents living in non-smoking households in the Boston area. Participants were interviewed about personal TSE in various locations in the past 7 days and completed a diary of home TSE for 7 days. Self-reported TSE was validated against measurable saliva cotinine (lower limit of detection (LOD 0.02 ng/ml and airborne apartment nicotine (LOD 5 ng. Correlations, estimates of inter-measure agreement, and logistic regression assessed associations between self-reported TSE items and measurable cotinine and nicotine.Cotinine and nicotine levels were low in this sample (median = 0.026 ng/ml and 0.022 μg/m3, respectively. Prevalence of detectable personal TSE was 66.3% via self-report and 57.0% via measurable cotinine (median concentration among those with cotinine>LOD: 0.057 ng/ml, with poor agreement (kappa = 0.06; sensitivity = 68.9%; specificity = 37.1%. TSE in the home, car, and other peoples' homes was weakly associated with cotinine levels (Spearman correlations rs = 0.15-0.25, while TSE in public places was not associated with cotinine. Among those with airborne nicotine and daily diary data (n = 161, a smaller proportion had household TSE via self-report (41.6% compared with measurable airborne nicotine (53.4% (median concentration among those with nicotine>LOD: 0.04 μg/m3 (kappa = 0.09, sensitivity = 46.5%, specificity = 62.7%.Self-report alone was not adequate to identify individuals with TSE, as 31% with measurable cotinine and 53% with measurable nicotine did not report TSE. Self-report of TSE in private indoor spaces outside the home was most associated with measurable cotinine in this low-income non-smoking population.

    Full Text Available The purpose of this article is to discuss two perspectives on Latter-day Saints’ (Mormons' temple open houses. First, that of the Latter-day Saints themselves, who are placed in a delicate situation as they present the temple to the public while simultaneously desiring to preserve its esoteric nature. What do they want to accomplish and how do they go about doing it? Second, the perspective of the public, whose reactions exemplify layman views of what it can be like to peek into a sacred and esoteric world foreign to oneself. What kinds of forms can their thoughts take at Mormon temple open houses? The particular case considered in this article is the autumn 2006 open house at the Helsinki Finland temple.

  7. Evaluation of Energy Use in Public Housing in Lagos, Nigeria: Prospects for Renewable Energy Sources

    Directory of Open Access Journals (Sweden)

    Isidore Chukwunweike Ezema

    2016-02-01

    Full Text Available Even though domestic energy can be from either renewable or non-renewable sources, the former is preferred because of its role in reducing both the operational energy intensity and carbon footprint. Given the positive role renewable energy plays in the energy mix, this paper examined the pattern of operational energy use with particular reference to the renewable and non-renewable energy content in medium and high density public residential buildings in Lagos, Nigeria. A survey research method was adopted for primary data collection while data analysis was by descriptive statistics. The study found that renewable energy use in the residential units is very low. In contrast, there was high dependence of the occupants on non-renewable direct fuel combustion through the use of fossil fuel-driven privately-owned electricity generators for electricity supply as a result of the inadequate supply from the national grid. In addition to the relatively high operational energy intensity observed in the studied buildings, the findings have implications for the safety, health and wellbeing of the building occupants as well as for carbon emissions from the buildings and for overall environmental sustainability. Recommendations to increase renewable energy use in new buildings and as retrofits in existing buildings were made.

  8. Challenge-driven design for public housing: The case of Hong Kong

    Directory of Open Access Journals (Sweden)

    Ying Deng

    2016-06-01

    Full Text Available Public housing (PH has existed in Hong Kong for six decades. Previous and current challenges that have been encountered over time function as a collective driver for design progression. However, such challenges have remained under research to be able to draw useful lessons from them. To understand how this established motif can suit the sustainability-conscious era, this study uses Hong Kong as a representative case for sub-tropical compact cities by critiquing its PH design against multiple constraints. The objective of this study is to trace the historical relationships between challenges and design progress as well as to assess current and future implications of sustainability trends on PH design. By synthesizing data from literature, policy documents, and empirical evidence, this research develops an evolution map for PH design in Hong Kong that is driven by seven major challenges. Based on this map, a conceptual framework for intersecting considerations that envisages five main future prospects toward future PH design is also established.

    2008-03-01

    To identify, compare, and analyze the social networks of two groups of poor, older adults in two types of public housing projects in Chile, in terms of the types of relationships and the frequency and purpose of their interactions, before and after moving to their new homes. A descriptive study was conducted of public housing beneficiaries in apartment buildings versus condominiums. The study pool was the group of people assigned to housing in buildings (n = 152) and condominiums (n = 124) from 1998 to 2001. A questionnaire was administered in their homes. Most study participants indicated that the move to public housing meant leaving their old neighborhood for a new one, a change that, among other consequences, produced changes in their social networks. In general, both groups have similar social networks, with their children being the strongest source of support, both before and after the move. After the move, social interaction generally decreased, except among the adults living in apartment buildings, for whom it increased slightly with family members, and in a superficial manner, with others who had weak connections and were neither friends nor family. Interactions with establishments also decreased, although interactions with senior services increased for the condo residents from 28% to 65% and for apartment residents from 31% to 45%. It is recommended that similar programs strive to preserve and strengthen the social networks in place prior to moving and encourage the formation of relationships in the new residences.

  10. Profit is a dirty word: the development of the public baths and wash-houses in Britain 1847-1915.

    Science.gov (United States)

    Sheard, S

    2000-04-01

    Researh on sanitary reform in nineteenth-century Britain has focused mainly on the introduction of large-sanitary infrastructure, especially waterworks and sewage systems. Other sanitary measures such as the provision of public baths and wash-houses have been ignored, or discussed in the limited context of working-class responses to middle-class sanitarianism. Yet by 1915 public baths and wash-houses were to be found in nearly every British town and city. A detailed analysis of these 'enterprises' can provide a useful way of understanding the changing priorities of public health professionals and urban authorities as well as the changing attitudes of the working classes. Connections between personal cleanliness and disease evolved during the century, particularly after the formation of germ theory in the 1880s. This paper demonstrates how the introduction of public baths and wash-houses in Liverpool, Belfast, and Glasgow was initially a direct response to sanitary reform campaigns. It also shows that the explicit public health ideology of these developments was constantly compromised by implicit concerns about municipal finance and the potential profit that such enterprises could generate. This city-based analysis shows that this conflict hindered the full sanitary benefit which these schemes potentially offered.

    Full Text Available This paper examines the design quality of People's Housing Project (Program Perumahan Rakyat or PPR low cost high rise flats developed by the National Housing Department (Jabatan Perumahan Negara or JPN in Kuala Lumpur since the 1998. Quality Function Deployment method is used as a tool to analyze the current status and to prioritize the demanded quality from the selected PPR low-cost high rise flats' users. The study revealed that factors in determining a quality low-cost high-rise flat arranged in descending degrees of importance are house safety, provision of public amenities, unit internal environment, maintenance and surrounding environment, location, sanitary fittings, unit size, type of house, material used, unit internal layout, quality of workmanship, structure of the house and appearance. A Quality Chart for PPR low-cost high-rise flats in Kuala Lumpur was presented. Authority (47 per cent has the highest relative degree of importance in determining the quality of PPR flats, followed by Design Element (34 per cent and Quality of Living (19 per cent. Accordingly, the success of the schemes relies strongly on effective control and enforcement by the authorities. However, it can be improved by tackling on the Design Element (Architectural, whereby a revised typical unit layout plan and typical details have been proposed at the last section of the paper.

  17. The politics of partnerships: a study of police and housing collaboration to tackle anti-social behaviour on Australian public housing estates.

    Science.gov (United States)

    Jacobs, Keith

    2010-01-01

    This paper draws on the findings from a research project on partnership arrangements between the police and housing departments on three Australian public housing estates to tackle problems associated with illicit drug activity and anti-social behaviour (ASB). The analysis focused on the setting up of the partnerships and the interactions that followed from these institutional arrangements. The assumption that informs the paper is that when studying partnerships there is a need for a more critically framed analysis. The temptation to posit "a successful model" of what partnership entails and then to judge practices in relation to this model is considerable, but it inevitably falls into the trap of constructing a narrative of partnership success or failure in terms of individual agency (that is, the degree of commitment from individuals). The analysis undertaken in this paper has therefore sought to fathom a more complex set of organizational processes. Rather than confine the discussion to issues of success and failure, the study foregrounds the subjective accounts of individuals who work within partnership and the constraints they encounter. The paper therefore makes explicit the cultural tensions within and across agencies, contestation as to the extent of the policy "problem," and the divergent perspectives on the appropriate modes of intervention.

    2000-09-29

    Fluor Fernald, Inc. has been progressively improving Decontamination and Dismantlement (D&D) at the Department of Energy's Fernald Environmental Management Project by applying new technologies and better methodologies to the work. Demolition issues existed in the past that necessitated new or improved solutions to maintain worker safety, protect the environment and accomplish the work in a cost effective manner. Lessons learned from D&D of 80 structures has led to a systematic approach, which can be implemented in various D&D arenas. When facility production was halted, hold-up material and process residues remained in the process piping and components. Over 500,000 pounds of material was removed by workers who completed the tasks two years ahead of schedule, $7 million under budget and with an excellent safety record. This success was the result of detailed planning and irdision of lessons learned as work progressed from facility to facility. Work sequences were developed that reduced airborne contamination. Demolition of structures has been performed at Fernald by carefully selected and qualified subcontractors. Asbestos and lead abatement, equipment, piping and conduit removal, and structural demolition have been completed to progressively higher performance specifications developed by Fluor Fernald based on lessons learned during execution. Safety continues to be the primary consideration in performing potentially hazardous work. Technologies such as hydraulic shears have been developed and used to keep workers away from danger. A new technology, ''Cool Suits,'' has been demonstrated to help prevent heat stress when anti-contamination clothing is required in elevated temperature working conditions. For tall structures, implosion technologies have been employed with progressively improved results, Several other new technologies have been evaluated by Fluor Fernald and applied by subcontractors. The improved technologies included the oxy

  20. Effect of Co-Composting Cattle Manure with Construction and Demolition Waste on the Archaeal, Bacterial, and Fungal Microbiota, and on Antimicrobial Resistance Determinants.

    Agricultural operations generate large quantities of manure which must be eliminated in a manner that is consistent with public health guidelines. Meanwhile, construction and demolition waste makes up about 25% of total solid municipal waste. Co-composting of manure with construction and demolition waste offers a potential means to make manure safe for soil amendment and also divert construction and demolition waste from municipal landfills. Therefore, the archaeal, bacterial, and fungal microbiota of two different types of composted cattle manure and one co-composted with construction and demolition waste, were assessed over a 99-day composting period. The microbiota of the three compost mixtures did not differ, but significant changes over time and by sampling depth were observed. Bacillus and Halocella, however, were more relatively abundant in composted manure from cattle fed dried distillers' grains and solubles. Proteobacteria and Bacteroidetes were enriched at day 0 and Firmicutes at day 99. The fungal genus Kernia was the most relatively abundant overall and was enriched at day 0. The concentration of 12 antimicrobial resistance determinants in the compost mixtures was also determined, and 10 of these determinants decreased significantly from days 0 to 99. The addition of construction and demolition waste did not affect the persistence of antimicrobial resistance genes or community structure of the compost microbiota and therefore co-composting construction and demolition waste with cattle manure offers a safe, viable way to divert this waste from landfills.

    2017-01-01

    Full Text Available Huge volume of project information are generated during the life cycle of an AEC projects. These project information are categorized in to technical and administrative information and managed through appropriate processes. There are many tools such as Document Management Systems, Building Information Modeling (BIM available to manage and integrate the technical information. However, the administrative information and its related processes such as the payment, status, authorization, approval etc. are not effectively managed. The current study aims to explore the administrative information management process of a local housing delivery public agency. This agency manages more than 2000 housing projects at any time of a year. The administrative processesare characterized withdelivery inconsistencies among various project participants. Though there are many commercially available process management systems, there exist limitations on the customization of the modules/ systems. Hence there is a need to develop an information management system which can integrates and manage these housing projects processes effectively. This requires the modeling of administrative processes and its interfaces among the various stakeholder processes. Hence this study aims to model the administrative processes and its related information during the life cycle of the project using IDEF0 and IDEF1X modeling. The captured processes and information interfaces are analyzed and appropriate process integration is suggested to avoid the delay in their project delivery processes. Further, the resultant model can be used for effectively managing the housing delivery projects.

    African American women in urban, high poverty neighborhoods have high rates of smoking, difficulties with quitting, and disproportionate tobacco-related health disparities. Prior research utilizing conventional "outsider driven" interventions targeted to individuals has failed to show effective cessation outcomes. This paper describes the application of a community-based participatory research (CBPR) framework to inform a culturally situated, ecological based, multi-level tobacco cessation intervention in public housing neighborhoods. The CBPR framework encompasses problem identification, planning and feasibility/pilot testing, implementation, evaluation, and dissemination. There have been multiple partners in this process including public housing residents, housing authority administrators, community health workers, tenant associations, and academic investigators. The advisory process has evolved from an initial small steering group to our current institutional community advisory boards. Our decade-long CBPR journey produced design innovations, promising preliminary outcomes, and a full-scaled implementation study in two states. Challenges include sustaining engagement with evolving study partners, maintaining equity and power in the partnerships, and long-term sustainability of the intervention. Implications include applicability of the framework with other CBPR partnerships, especially scaling up evolutionary grassroots involvement to multi-regional partnerships.

  5. Rat sightings in New York City are associated with neighborhood sociodemographics, housing characteristics, and proximity to open public space.

    Rats are ubiquitous in urban environments and, as established reservoirs for infectious pathogens, present a control priority for public health agencies. New York City (NYC) harbors one of the largest rat populations in the United States, but surprising little study has been undertaken to define rat ecology across varied features of this urban landscape. More importantly, factors that may contribute to increased encounters between rats and humans have rarely been explored. Using city-wide records of rat sightings reported to the NYC Department of Health and Mental Hygiene, this investigation sought to identify sociodemographic, housing, and physical landscape characteristics that are associated with increased rat sightings across NYC census tracts. A hierarchical Bayesian conditional autoregressive Poisson model was used to assess these associations while accounting for spatial heterogeneity in the variance. Closer proximity to both subway lines and recreational public spaces was associated with a higher concentration of rat sightings, as was a greater presence of older housing, vacant housing units, and low education among the population. Moreover, these aspects of the physical and social landscape accurately predicted rat sightings across the city. These findings have identified specific features of the NYC urban environment that may help to provide direct control targets for reducing human-rat encounters.

    Presently, it is noticeable that there is a significant influence of public open space about house price, especially in many developed nations. Literature suggests the relationship between the two aspects give impact on the housing market, however not many studies undertaken in Malaysia. Thus, this research was initiated to analyse the relationship of open space and house price via the techniques of GIS-Hedonic Pricing Model. In this regards, the GIS tool indicates the pattern of the relationship between open space and house price spatially. Meanwhile, Hedonic Pricing Model demonstrates the index of the selected criteria in determining the housing price. This research is a perceptual study of 200 respondents who were the house owners of double-storey terrace houses in four townships, namely Bandar Baru Bangi, Taman Melawati, Subang Jaya and Shah Alam, in Klang Valley. The key research question is whether the relationship between open space and house price exists and the nature of its pattern and intensity. The findings indicate that there is a positive correlation between open space and house price. Correlation analysis reveals that a weak relationship (rs research has achieved its research aims and thus, offers the value added in applying the GIS-Hedonic pricing model in analysing the influence of open space to the house price in the form of spatially and textually.

  10. Demolition of one of the old barracks

    CERN Multimedia

    2002-01-01

    Many people at CERN will no doubt remember having rented accommodation in the four barracks-type huts near Entrance A. The rates were certainly rock bottom but it was hardly the Ritz! Put up at the end of the 1950s, they were abandoned in favour of the Saint-Genis-Pouilly hostel and the Meyrin site hostels. As they no longer meet current safety standards, they will all ultimately have to be demolished. One of them, situated immediately below the HV power line, has just been demolished at the request of the Swiss electricity company Energie Ouest Suisse. With its demolition, a little piece of CERN's social history has gone for ever.

  11. Entanglement Concentration with Quantum Non Demolition Hamiltonians

    Tatham, Richard

    2011-01-01

    We devise and examine two procrustean entanglement concentration schemes using Quantum Non- Demolition (QND) interaction Hamiltonians in the continuous variable regime, applicable for light, for atomic ensembles or in a hybrid setting. We thus expand the standard entanglement distillation toolbox to the use of a much more general, versatile and experimentally feasible interaction class. The first protocol uses Gaussian ancillary modes and a non-Gaussian post-measurement, the second a non-Gaussian ancillary mode and a Gaussian post-measurement. We explicitly calculate the density matrix elements of the non-Gaussian mixed states resulting from these protocols using an elegant Wigner-function based method in a numerically efficient manner. We then quantify the entanglement increase calculating the Logarithmic Negativity of the output state and discuss and compare the performance of the protocols.

    宜黄事件具有某种标志性意义,它颠覆了当代中国抗争政治的刻板印象,创造了一个新的抗争政治类型。宜黄事件原本是一个普通的钉子户抗争事件,在进入媒体的视野之前,它只是底层政治的一部分,当事人采用的基本上属于"弱者的武器"的方式,并且是地方性的、特殊的和双轨的,显著性和协同性都不高。由于媒介动员将政策的内在张力呈现于公众视野,钉子户利用这一政治机遇结构,不断创新了抗争表演,从而使宜黄事件发生了规模转变和极化,最终使事件发展成为一场要求保护弱势群体利益,发动制度变革的专业化社会运动的一部分,宜黄事件也就具有了普适性的、模式化的和自主的特征。宜黄事件的遣散是因为钉子户和媒体的抗争目标出现了竞争,而并非明确的适度制度化所致,这是当代中国国家建设中"反体制"的体制重建的一部分。%The contention event of Yihuang in September, 2010 is of great significance because it has changed the contention routine in contemporary China by adopting a new type of contentious politics. Before it became the media focus, Yihuang event was just another ordinary occurrence of residents resisting demolition of their houses, a part of the subaltern politics. The main contention strategies taken by the families under the order to move typically including negotiation with the local government in charge of demolition, intercepting visits to appeal, and seeking media attention. These are "weapons of the weak", parochial, local-specific, and bifurcated~ therefore, of low salience and poor coordination, usually unsuccessful to achieve contention objectives. This time, the Zhong family adopted an extreme contention means of self-immolation. Since the occurrence of this event, the large-scale involvement of the media has presented the inherent tension of policies to the public, and the demolition

    Introduction Exposure to secondhand smoke is problematic for residents living in multiunit housing, as the smoke migrates through shared ventilation systems, unsealed cracks, and door spaces. The objective of our research was to assess resident exposure to secondhand smoke, support for no-smoking policies, and the health impacts of no-smoking policies in multiunit housing. Methods Surveys of 312 heads of households who resided in 1 of 3 multiunit buildings managed by a Colorado public housing authority were administered before and after implementation of a no-smoking policy that prohibited smoking in all resident apartments and all indoor common areas. A matched-pairs analysis of initial surveys and 15-month post-policy implementation surveys for 115 respondents was conducted. Results Decreases were found in the number and percentage of smokers who smoked every day and the number of cigarettes smoked per day, and 30% had quit smoking 15 months after policy implementation. The percentage of residents who smelled secondhand smoke indoors declined significantly. A significant decrease in breathing problems was found after policy implementation. Although decreases were found in the incidence of asthma attacks, emphysema/chronic obstructive pulmonary disease, eye irritation, colds, nasal congestion, and ear/sinus infections, these decreases were not significant. Conclusion Consistent findings across nearly all variables tested suggest that no-smoking policies reduce resident exposure to secondhand smoke, lower the incidence of secondhand smoke–associated breathing problems, decrease daily smoking and cigarette consumption, encourage smoking cessation, and increase quit attempts. If implemented in all multiunit housing, these policies could reduce exposure to secondhand smoke and health problems associated with secondhand smoke, promote smoking cessation, and reduce cigarette consumption.

  16. Preferences, power and policy outcomes in public policy in Iceland: The Icelandic Housing Fund fiasco 2003-2005

    2014-12-01

    Full Text Available This research focuses on the interplay of politics, bureaucracies and markets in Iceland. It aims to explain theoretically how politics and bureaucracies operate when a coalition government makes and implements decisions in a policy environment in which decisions and their effects intersect public bureaucracies’ and markets’ boundaries. The decision to raise the limits of Housing Fund mortgages in 2003 is a case examined by agenda-setting theories in public policy. The research is based on the data from parliamentary Special Investigation reports on the collapse of the Icelandic banks and the Housing Fund as well as the author’s interviews home and abroad. The research shows that, when made, the decision ignited competition between the Housing Fund and the recently privatized banks and that between the banks themselves. The Independence Party’s attempts to delay implementation of the decision involved system change backed by an instrument designed to stem a run on the Fund. The impact of this instrument (a tax on pre-payments was incompatible with the Progressive Party’s political interests. In a hasty attempt to implement its election promises, the Progressive Party ignored the fact that the Fund was operating within a transformed financial system. The conclusions indicate that those who think long-term in politics make policies by changing system dynamics, those who think short-term change programmes. System dynamics, however, change the balance of power and influence between actors, leaving legacies which curb the government’s attempt at change, unless consolidated and sustained political authority and will are established to see changes through.

  19. Evaluation and Optimization of the Financial Sustainability of Public Rental Housing Projects: A Case Study in Nanjing, China

    2016-04-01

    Full Text Available In recent years, Chinese governments have launched ambitious plans in developing public rental housing (PRH, which are almost impossible to accomplish without the involvement of the private sector. Yet, very few quantitative studies have been carried out to evaluate the financial sustainability of PRH projects in China, especially from the perspective of the private sector. This knowledge gap is bridged through the evaluation of the financial sustainability of a hypothetical privately owned PRH project in Nanjing, China as a case study, utilizing data of a state-owned PRH project and the classic discounted cash flow method. The results indicate that the studied project is financially infeasible, which means that private companies would not be willing to participate in the provision of public rental housing, if they merely focus on profits. Then, the most cost-effective optimization measure of the studied case is quantitatively selected from four possible optimization scenarios, leading to a financial balance. This paper presents the current financial status of Chinese PRH projects, thereby providing policy makers with useful references to effectively accelerate the private sector’s provision of PRH in China.

    2009-11-01

    The relative efficacy of gravid and under-house CO2 traps for monitoring mosquito species of public health importance within the Houston metroplex area was assessed. Gravid and under-house traps were colocated at 10 sites and monitored weekly between 1 March to 31 May 2007. The most numerous species caught was Culex pipiens quinquefasciatus Say. Other species of public health importance caught in gravid and under-house traps included Culex restuans Theobald, Aedes aegypti (L.), and Aedes albopictus Skuse. Adjusting for the week of collection, gravid traps caught significantly more mosquitoes (mean 23.1 per trap) in the study area than under-house traps (mean 3.6 per trap). However, under-house traps caught a greater variety of mosquito species (13) than gravid traps (11). Gravid and under-house traps only caught nine of 15 of the same mosquito species during the study period. In this study area, gravid traps should be used as the primary method of surveillance for mosquito-borne diseases of public health importance during the early part of the season, because of greater catch numbers of mosquitoes that pose a public health risk.

    Housing right is seen tendentiously as basic right of constitution with the feature of subjective right of asking for on the level of constitutional assurance.

  5. Mechanical Demolition of Buildings with Concrete Asbestos Board Siding: Methodology, Precautions, and Results at the Hanford Central Plateau - 12417

    Energy Technology Data Exchange (ETDEWEB)

    Kehler, Kurt [Decommissioning and Demolition, CH2M HILL Plateau Remediation Company, Richland, Washington (United States)

    2012-07-01

    Since the start of its contract in 2008, the CH2M Hill Plateau Remediation Company (CH2M HILL) has demolished 25 buildings with concrete asbestos board (CAB) siding using mechanical means. While the asbestos contained in CAB siding is not friable in its manufactured form, concerns persist that mechanical methods of demolition have the potential to render the asbestos friable and airborne, therefore posing a health risk to demolition workers and the public. CH2M HILL's experience demonstrates that when carefully managed, mechanical demolition of CAB siding can be undertaken safely, successfully, and in compliance with regulatory requirements for the disposal of Class II Asbestos-Containing Material (ACM). While the number of buildings demolished at Hanford and the number of samples collected does not make a conclusive argument that CAB cannot be made friable with normal demolition techniques, it certainly provides a significant body of evidence for the success of the approach. Of course, there are many factors that affect how to demolish a structure and dispose of the waste. These factors will impact the success depending on each site. The most obvious factors which contribute to this success at Hanford are: 1. The availability of onsite waste disposal where the handling and cost of asbestos-containing waste is not much different than other potentially contaminated waste. Therefore, segregation of demolition debris from the potential asbestos contamination is not necessary from a debris handling or asbestos disposal aspect. 2. The space between structures is typically significant enough to allow for large exclusion zones. There are not many restrictions due to cohabitation issues or potential contamination of adjacent facilities. 3. The willingness of the regulators and client to understand the industrial safety issues associated with manual CAB removal. (authors)

  8. Evidence of public engagement with science: visitor learning at a zoo-housed primate research centre.

    Directory of Open Access Journals (Sweden)

    Bridget M Waller

    Full Text Available Primate behavioural and cognitive research is increasingly conducted on direct public view in zoo settings. The potential of such facilities for public engagement with science is often heralded, but evidence of tangible, positive effects on public understanding is rare. Here, the effect of a new zoo-based primate research centre on visitor behaviour, learning and attitudes was assessed using a quasi-experimental design. Zoo visitors approached the primate research centre more often when a scientist was present and working with the primates, and reported greater awareness of primates (including conservation compared to when the scientist was not present. Visitors also reported greater perceived learning when the scientist was present. Installation of information signage had no main effect on visitor attitudes or learning. Visitors who interacted with the signage, however, demonstrated increased knowledge and understanding when asked about the specific information present on the signs (which was related to the ongoing facial expression research at the research centre. The findings show that primate behaviour research centres on public view can have a demonstrable and beneficial effect on public understanding of science.

      The first public rental housing of partial city has already stepped in distribution phase with the phenomenon of deserted vacancy. In order to promote benign docking between demand for and supply of Dalian public rental housing,the paper takes Dalian Quanshui public housing which is about to enter the lottery stage as an example,and uses questionnaire survey on the attitude and confidence of the public rental housing from the potential demanders for housing. The questionnaire results are analyzed based on testing of validity and reliability. The results indicate that the public currently is lacking confidence and acceptance with a grain of salt about public rental housing security system. Finally,the article puts forward five proposals to improve the Dalian public rental housing system:Guiding the concept of residential housing consumption correctly,encouraging social forces to participate in raising public rental housing,establishing scientific and reasonable rent,relieving the household registration restriction and improving the mechanism of management.%  针对部分城市首批公租房在配租阶段出现的冷清空置现象,为促使大连公租房供需之间实现良性对接,以即将进入摇号阶段的泉水公租房为例,通过问卷形式调查大连市潜在住房需求者对公租房的态度和信心情况。在问卷效度和信度检验的基础上,对问卷结果进行分析,结果显示,当前市民对公租房保障体系信心不足。针对大连市公租房建设和实施现状提出正确引导居民住房消费观念、鼓励社会力量参与筹集公租房房源、制定科学合理的租金、放宽户籍门槛以及完善管理机制等建议。

    Survey data indicate that young Black female smokers living in public housing are heavier smokers and have weaker motivation to quit, health beliefs and social environment less conducive to cessation, and less knowledge of where to get help to quit than other young Black female smokers in metropolitan Chicago. Compared with White women, the latter, other Black women smoke fewer cigarettes daily and have a stronger desire to quit and more concern about health reasons for quitting, but have a weaker belief in the risk of lung cancer from smoking, greater concern about quitting difficulties, and less knowledge of where to get help to quit. Low education, not race, is associated with higher smoking prevalence and less social pressure to quit or support for quitting.

  16. THE EFFECT OF VESSEL SUPPLY ON SHIP-DEMOLITION PRICES

    2017-02-01

    Full Text Available The ship-demolition is one of the four main markets that form the shipping industry and plays an important role on the seaborne trade, as it mitigates imbalances between supply and demand for transportation services by adjusting the merchant fleet supply. The aim of this study is to examine whether the factors that determine the supply of vessels for demolition are capable of affecting materially the ship-demolition price formation. The availability of ships for demolition is primarily a function of the fleet’s age and the conditions on the freight and secondhand markets. The analysis is conducted on the crude tanker and the bulk carrier segments and the vector autoregressive model methodology is employed, whereby the effect of both the supply and the demand factors on the ship-demolition prices is examined. The results indicate that the supply side has limited effect on the price formation in the industry, which is driven by the demand for the steel-scrap commodity.

    Research interests in addressing construction and demolition (C&D) waste management issues have resulted in a large amount of publications during the last decade. This study demonstrates that there is no systematic examination on the research development in literature in the discipline of C&D waste management. This study presents the latest research trend in the discipline through analyzing the publications from 2000 to 2009 in eight major international journals. The analysis is conducted on the number of papers published annually, main authors' contributions, research methods and data analysis methods adopted, and research topics covered. The results exhibit an increasing research interest in C&D waste management in recent years. Researchers from developed economies have contributed significantly to the development of the research in the discipline. Some developing countries such as Malaysia and China have also been making good efforts in promoting C&D waste management research. The findings from this study also indicate that survey and case study are major methods for data collection, and the data are mostly processed through descriptive analysis. It is anticipated that more future studies on C&D waste management will be led by researchers from developing economies, where construction works will remain their major economic activities. On the other hand, more sophisticated modeling and simulating techniques have been used effectively in a number of studies on C&D waste management research, and this is considered a major methodology for future research in the discipline. C&D waste management will continue to be a hot research topic in the future, in particularly, the importance of human factors in C&D waste management has emerged as a new challenging topic.

    2004-12-01

    Full Text Available Abstract Background Children in urban public housing are at high risk for asthma, given elevated environmental and social exposures and suboptimal medical care. For a multifactorial disease like asthma, design of intervention studies can be influenced by the relative prevalence of key risk factors. To better understand risk factors for asthma morbidity in the context of an environmental intervention study, we conducted a detailed baseline evaluation of 78 children (aged 4–17 years from three public housing developments in Boston. Methods Asthmatic children and their caregivers were recruited between April 2002 and January 2003. We conducted intake interviews that captured a detailed family and medical history, including questions regarding asthma symptom severity, access to health care, medication usage, and psychological stress. Quality of life was evaluated for both the child and caregiver with an asthma-specific scale. Pulmonary function was measured with a portable spirometer, and allergy testing for common indoor and outdoor allergens was conducted with skin testing using the prick puncture method. Exploratory linear and logistic regression models evaluating predictors of respiratory symptoms, quality of life, and pulmonary function were conducted using SAS. Results We found high rates of obesity (56% and allergies to indoor contaminants such as cockroaches (59% and dust mites (59%. Only 36% of children with persistent asthma reported being prescribed any daily controller medication, and most did not have an asthma action plan or a peak flow meter. One-time lung function measures were poorly correlated with respiratory symptoms or quality of life, which were significantly correlated with each other. In multivariate regression models, household size, body mass index, and environmental tobacco smoke exposure were positively associated with respiratory symptom severity (p Conclusion Given the elevated prevalence of multiple risk factors

    Full Text Available In each country in the world, there is a strong need for all industries to reduce CO2 emissions for sustainable development as a preparation for climatic change. The biggest issue in many developed countries, including the United States, is to reduce CO2 emissions for the upcoming implementation of Carbon Emissions Trading. The construction industry, in particular, which accounts for up about 30% of CO2 emissions, will need studies on the amount of CO2 emissions. The purpose of this study is to present the most environmentally friendly and economical apartment house plan types according to the increasing number of layers by evaluating the amount of CO2 emissions and economic efficiency. The results indicated that flat and Y-shaped types are more eco-friendly and economical in lower levels of less than 20 stories. However, the L-shaped type is more highly eco-friendly and economically efficient in higher levels of more than 20 stories. The results of this paper would help to make a decision on the building types and the number of stories in the early stages of construction.

  20. Implications of global climate change for housing, human settlements and public health.

    Global climate change has profound implications for human societies. The present---ecologically unsustainable--trajectory of human development fails to provide for the basic needs of a substantial fraction of the global population, while diminishing the prospects for future generations. Human-caused climate change has already begun to affect weather patterns, physical and biological phenomena, and vulnerable human communities. Because the social processes of production and consumption have their own momentum, and because carbon dioxide has a long atmospheric lifetime, further climate change is inevitable over the coming century, even allowing for the adoption of mitigation measures. This situation implies that we should also try to reduce, and where possible to prevent, the adverse effects of climate changes by planned adaptation. Will human settlements be able to provide a healthy living environment and shelter from extreme climate events, such as cyclones and heat waves? In this paper, we review the nexus between human health, climate change, and the planning of housing and human settlements. We conclude that adapting to a rapidly changing global environment will be a major challenge, in the context of increasing population and per capita consumption, without increasing pressures on natural systems. Energy-efficient cities and the creation of opportunities for poor countries will be important elements of people centered, ecologically sustainable, development in the twenty-first century.

    2010-06-01

    Full Text Available Zimbabwe has a sombre housing crisis in all its urban centres. All attempts by the government to vary housing delivery systems to ameliorate the problem have proved futile as the backlog it inherited from the colonial masters continues to soar. The situation has however been exacerbated by 2005 demolitions and evictions in the country’s major cities that destroyed homes and businesses leaving the majority of the poor and disadvantaged segments of society in deeper poverty, deprivation and destitution. The main challenge to housing the urban poor is housing finance. Public funds are meagre and private funds are not accessible to the poor due to lack of collateral security and inability to service the loans. Fascinatingly, the poor’s income comes from informal sector activities that absorbs a large percentage of the labour force and keeps the economy going while the large modern enterprises continue to reel under the economic downturn. Unfortunately the Zimbabwean informal sector has generally been perceived as a nuisance, a haven for criminals and a menace. Evidence shows that there is a strong relationship between the urban poor’s housing finance, informal sector activities and self-help housing strategies in Zimbabwe. In the pre-2005 Operation Murambatsvina era, the poor were making some construction progress as evidenced by the structures that had developed. This paper calls for active support and facilitation of the poor’s sources of income, and advocates for the involvement of other players such as the private sector and the international community in housing the poor. The Zimbabwe government’s plan to house the homeless and poor on its 250 000 stands countrywide through self-help programmes can only be successful if their sources of income are promoted and facilitated.

    Full Text Available The public service enterprises are victims of crimes and felonies which may reduce their capacity to perform their functions. These enterprises expend much money and effort in order to prevent those criminal behaviors. For this reason they ask from the authorities more efficient measures against crime; however, such enterprises may feel that they are not being given sufficient importance and/or remedies in dealing with such crime. The aim paper of this is not to study the problem from de substantive criminal law point of view. Rather, this paper’s goal is to study the Colombia’s Rules of Criminal Procedure, which regulate the investigation of this kind of crime. The article will look particularly at the competency of the relevant authorities at the investigative stages. Finally, it will make some recommendations regarding a proper route towards the investigation of these criminal behaviors.

    Cockroaches and mice, which are common in urban homes, are sources of allergens capable of triggering asthma symptoms. Traditional pest control involves the use of scheduled applications of pesticides by professionals as well as pesticide use by residents. In contrast, integrated pest management (IPM) involves sanitation, building maintenance, and limited use of least toxic pesticides. We implemented and evaluated IPM compared with traditional practice for its impact on pests, allergens, pesticide use, and resident satisfaction in a large urban public housing authority. We assigned IPM or control status to 13 buildings in five housing developments, and evaluated conditions at baseline, 3 months, and 6 months in 280 apartments in Brooklyn and Manhattan, in New York City (New York). We measured cockroach and mouse populations, collected cockroach and mouse urinary protein allergens in dust, and interviewed residents. All statistical models controlled for baseline levels of pests or allergens. Compared with controls, apartments receiving IPM had significantly lower counts of cockroaches at 3 months and greater success in reducing or sustaining low counts of cockroaches at both 3 and 6 months. IPM was associated with lower cockroach allergen levels in kitchens at 3 months and in beds and kitchens at 6 months. Pesticide use was reduced in IPM relative to control apartments. Residents of IPM apartments also rated building services more positively. In contrast to previous IPM studies, which involved extensive cleaning, repeat visits, and often extensive resident education, we found that an easily replicable single IPM visit was more effective than the regular application of pesticides alone in managing pests and their consequences.

  15. Estimation of construction and demolition waste using waste generation rates in Chennai, India.

    Science.gov (United States)

    Ram, V G; Kalidindi, Satyanarayana N

    2017-06-01

    A large amount of construction and demolition waste is being generated owing to rapid urbanisation in Indian cities. A reliable estimate of construction and demolition waste generation is essential to create awareness about this stream of solid waste among the government bodies in India. However, the required data to estimate construction and demolition waste generation in India are unavailable or not explicitly documented. This study proposed an approach to estimate construction and demolition waste generation using waste generation rates and demonstrated it by estimating construction and demolition waste generation in Chennai city. The demolition waste generation rates of primary materials were determined through regression analysis using waste generation data from 45 case studies. Materials, such as wood, electrical wires, doors, windows and reinforcement steel, were found to be salvaged and sold on the secondary market. Concrete and masonry debris were dumped in either landfills or unauthorised places. The total quantity of construction and demolition debris generated in Chennai city in 2013 was estimated to be 1.14 million tonnes. The proportion of masonry debris was found to be 76% of the total quantity of demolition debris. Construction and demolition debris forms about 36% of the total solid waste generated in Chennai city. A gross underestimation of construction and demolition waste generation in some earlier studies in India has also been shown. The methodology proposed could be utilised by government bodies, policymakers and researchers to generate reliable estimates of construction and demolition waste in other developing countries facing similar challenges of limited data availability.

    2003-04-01

    Full Text Available Abstract Background Methodological limitations make it difficult to quantify the public health benefits of energy efficiency programs. To address this issue, we developed a risk-based model to estimate the health benefits associated with marginal energy usage reductions and applied the model to a hypothetical case study of insulation retrofits in single-family homes in the United States. Methods We modeled energy savings with a regression model that extrapolated findings from an energy simulation program. Reductions of fine particulate matter (PM2.5 emissions and particle precursors (SO2 and NOx were quantified using fuel-specific emission factors and marginal electricity analyses. Estimates of population exposure per unit emissions, varying by location and source type, were extrapolated from past dispersion model runs. Concentration-response functions for morbidity and mortality from PM2.5 were derived from the epidemiological literature, and economic values were assigned to health outcomes based on willingness to pay studies. Results In total, the insulation retrofits would save 800 TBTU (8 × 1014 British Thermal Units per year across 46 million homes, resulting in 3,100 fewer tons of PM2.5, 100,000 fewer tons of NOx, and 190,000 fewer tons of SO2 per year. These emission reductions are associated with outcomes including 240 fewer deaths, 6,500 fewer asthma attacks, and 110,000 fewer restricted activity days per year. At a state level, the health benefits per unit energy savings vary by an order of magnitude, illustrating that multiple factors (including population patterns and energy sources influence health benefit estimates. The health benefits correspond to $1.3 billion per year in externalities averted, compared with $5.9 billion per year in economic savings. Conclusion In spite of significant uncertainties related to the interpretation of PM2.5 health effects and other dimensions of the model, our analysis demonstrates that a risk

    Directory of Open Access Journals (Sweden)

    Joyce Maria de Araujo

    2007-04-01

    Full Text Available A utilização de caçambas metálicas em áreas públicas para acondicionar resíduos da construção e demolição-RCD tem sido incrementada, em cidades brasileiras, a partir da década de 1990, contribuindo para o adensamento do mobiliário urbano e modificando a paisagem urbana. Este equipamento é utilizado para confinar os resíduos de modo a impedir sua dispersão no ambiente, facilitar sua coleta e transporte e evitar a exposição de moradores e transeuntes. A despeito dessas vantagens, as caçambas representam um perigo ao ambiente e à saúde pública. Com objetivo de verificar a interferência das caçambas nas ruas e calçadas e identificar situações de risco, foi realizado um estudo de campo envolvendo 58 caçambas estacionadas em 5 diferentes bairros da cidade de São Paulo. Aspectos como localização e disposição, identificação e uso de pintura reflexiva para prevenção de acidentes com veículos automotivos e conteúdo da caçamba foram observados. Os resultados indicaram a presença de não-conformidades, na maioria dos casos observados, como: localização inadequada, pintura reflexiva não existente ou apagada, quantidade excessiva de resíduos, presença de matéria orgânica ou resíduos perigosos, objetos cortantes ou pontiagudos extrapolando os limites da caçamba, dentre outros. Conclui-se que é necessário desenvolver uma abordagem integrada e ecossistêmica para estes elementos do mobiliário urbano, de modo a contemplar, além da questão de gerenciamento dos RCD, aspectos de saúde pública e ambiental e, ao mesmo tempo, preservar os valores estéticos e a paisagem urbana.

      增加公租房供给是我国住房保障政策的重点,而公租房定价是住房保障可持续发展的难题。基于BOT模式发展公租房,能够借助民营资本的综合优势解决政府财政资金相对紧缺与保障家庭支付能力不足的矛盾。基于保障性、公平性、可持续发展等原则,深入研究设计了BOT模式下的公租房定价机制,提出了采取名义租金、实际租金的“双租金制”和实行“租补分离”的定价思路。研究结果为完善我国住房保障制度提供了理论支持,也为公租房定价实践提供了重要参考。%Increasing the supply of public rental housing is the focus of China’s housing security policy. While the rent design is a critical issue for sustainable development of public rental housing. BOT could be applied to solve the contradictoriness between relative shortage of financial funds and poor ability of the Public in realizing government’s objectives with the comprehensive advantages of the Private’s capital and capability. Based on some basic principles such as indemnificatory,fairness and sustainable development,this paper conducts an in-depth study and designs a mechanism of pricing the rent of public rental housing. A‘double-rent’ system consists of nominal and real rent is proposed in which the rent paid by the lessee and the subsidy from the government are separated. The paper provides a theoretical basis to improve China's housing security system and an important practical reference for pricing the rent of public rental housing.

    1998-10-20

    Hanford, Fernald, Savannah River, and other sites are currently reviewing technologies that can be implemented to demolish buildings in a cost-effective manner. In order to demolish a structure properly and, at the same time, minimize the amount of dust generated from a given technology, an evaluation must be conducted to choose the most appropriate dust suppression technology given site-specific conditions. Thus, the purpose of this research, which was carried out at the Hemispheric Center for Environmental Technology (HCET) at Florida International University, was to conduct an experimental study of dust aerosol abatement (dust suppression) methods as applied to nuclear D and D. This experimental study targeted the problem of dust suppression during the demolition of nuclear facilities. The resulting data were employed to assist in the development of mathematical correlations that can be applied to predict dust generation during structural demolition.

    2011-08-01

    It may not be enough simply to know the global volume of construction and demolition waste (CDW) generated in a certain region or country if one wants to estimate, for instance, the revenue accruing from separating several types of materials from the input entering a given CDW recycling plant. A more detailed determination of the distribution of the materials within the generated CDW is needed and the present paper addresses this issue, distinguishing different buildings and types of operation (new construction, retrofitting and demolition). This has been achieved by measuring the materials from buildings of different ages within the Portuguese building stock, and by using direct data from demolition/retrofitting sites and new construction average values reported in the literature. An attempt to establish a benchmark with other countries is also presented. This knowledge may also benefit industry management, especially that related to CDW recycling, helping to optimize procedures, equipment size and operation and even industrial plant spatial distribution. In an extremely competitive market, where as in Portugal low-tech and high environmental impact procedures remain the norm in the construction industry (in particular, the construction waste industry), the introduction of a successful recycling industry is only possible with highly optimized processes and based on a knowledge-based approach to problems.

    The aims of this study were: 1) to explore the individual perceptions, experience and understandings of vitamin D deficiency (VDD) amongst African migrant women residing in high-rise public housing, 2) to identify the most useful sources of information about VDD among this population, and 3) to document the barriers and enablers to addressing VDD. The Health Belief Model was used to guide the study. Convenience sampling was used with women living in particular high-rise public housing. Five focus group discussions were conducted (n=30). Thematic analysis was used to code and categorise the data to develop a deeper, conceptual understanding of the issue. We found that participants were aware of VDD and could identify the impacts that VDD had on their health. Barriers to addressing VDD included the women's: 1) living conditions in Australia, 2) risk of skin cancer, and 3) cultural roles in the family. The most positive strategy for preventing and addressing VDD was peer information sharing. This study has highlighted the significant need for health promotion strategies to combat VDD in this population. Future health promoting public health strategies for this population should encompass community based peer education programs. This study demonstrates the critical role of qualitative inquiry in gaining a deeper understanding of VDD in a particular migrant community. It is clear that this issue requires a coordinated solution that must involve the community themselves. Health care professionals must take into consideration the multiple barriers that exist to address VDD which is a significant public health issue.

  17. Fatigue of reinforcing bars during hydro-demolition

    2017-05-01

    Reinforcing steel fractured during hydro-demolition of a reinforced concrete pier head due to low cycle flexural fatigue from vibration caused by impact of the high pressure water jet on the exposed length of the bars. Research into the fatigue performance of steel reinforcing steel tends to focus on the high cycle axial performance in reinforced concrete members and re-bending behaviour. However with the increasing use of hydro-demolition of concrete structures as part of remediation works care is required to ensure the steel reinforcement exposed to the high pressure jet of water is not going to suffer relatively low cycle flexural damage that may compromise the designed performance of the completed reinforced concrete structure. This paper describes the failure assessment, fatigue analysis, and metallographic examination that was undertaken. It was found that the rib to flank transition radius on the reinforcement steel was small enough to cause a significant stress concentration effect and was the location of fatigue crack growth. A relatively simple analysis using the maximum unrestrained cantilevered bar length and force exerted by the water jet was used to calculate the maximum expected bending moment. This was compared to the bending capacity at initiation of yielding at the rib flank transition accounting for stress concentration effects. This showed that the observed cyclic reversing ductile crack growth and fracture of the H25 bars was consistent with the loading applied. A method is proposed based on these observations to assess suitable limits for unrestrained bar lengths or maximum working offset of the water jet from the point of bar restraint when undertaking hydro-demolition work. The fatigue critical performance requirements of AS/NZS4671 500E bars are also therefore compared with those of BS4449:2005 and PN EN/ISO 15630-1:2011 for comparable 500C bars

    Intervention programs that change environments have the potential for greater population impact on obesity compared to individual-level programs. We began a cluster randomized, multi-component multi-level intervention to improve weight, diet, and physical activity among low-socioeconomic status public housing residents. Here we describe the rationale, intervention design, and baseline survey data. After approaching 12 developments, ten were randomized to intervention (n=5) or assessment-only control (n=5). All residents in intervention developments are welcome to attend any intervention component: health screenings, mobile food bus, walking groups, cooking demonstrations, and a social media campaign; all of which are facilitated by community health workers who are residents trained in health outreach. To evaluate weight and behavioral outcomes, a subgroup of female residents and their daughters age 8-15 were recruited into an evaluation cohort. In total, 211 households completed the survey (RR=46.44%). Respondents were Latino (63%), Black (24%), and had ≤ high school education (64%). Respondents reported ≤2 servings of fruits & vegetables/day (62%), visiting fast food restaurants 1+ times/week (32%), and drinking soft drinks daily or more (27%). The only difference between randomized groups was race/ethnicity, with more Black residents in the intervention vs. control group (28% vs. 19%, p=0.0146). Among low-socioeconomic status urban public housing residents, we successfully recruited and randomized families into a multi-level intervention targeting obesity. If successful, this intervention model could be adopted in other public housing developments or entities that also employ community health workers, such as food assistance programs or hospitals.

    Worldwide construction and demolition waste (CDW) is currently dumped. To close the building cycle and the building materials cycle by recycling CDW in high technical applications, the technical quality of stony materials must be improved. For this purpose, concrete rubbles and brick rubbles, the two major stony constituents of CDW, should be separated from each other. Based on the differences in density and content of Fe2O3 between the two materials, a wet method of jigging and a dry method of magnetic separation are effective,tested.

    Construction and demolition waste features two very important properties when considering its management options: the large amounts, and the low environmental hazardousness. Therefore, concrete waste can be recycled relatively easily: most common end-of-life option is utilization as unbound...... aggregates in road sub-bases, where it substitutes for natural aggregates such as gravel and crushed rocks. However, leaching of heavy metals may occur in such uncontrolled environmental conditions, and become a limiting factor for utilization. Therefore, proper assessment of leaching is crucial.

    Establishing an organization to promote organ donation and a good organ procurement team assure quality and improve performance on organ donation rates. Brazil's organ procurement structure is based on 2 models disseminated worldwide: the "Spanish model," based on in-house coordinators, and the "American organ procurement organization (OPO) model," with extra-hospital coordinators. In 2006, Brazil's Federal Government had formally introduced the in-house coordination model for every hospital equipped with a mechanical ventilator bed. In January 2012, the Rio de Janeiro State OPO, Programa Estadual de Transplantes, introduced an innovation in the organization of the in-house coordination model in 4 selected public hospitals with high organ donation potential. It consisted in launching full-time in-house coordination teams, with ≥1 physician and 2 nurses per hospital fully dedicated to organ procurement. The objectives were to observe the impact of this innovation in referral and organ donor conversion rates and to analyze the importance of middle managers in health care innovation implementation. Comparing the year before implementation (2011) and the year of 2014 showed that this innovation led to an overall increase in referrals-from 131 to 305 per year (+132%) and conversion rates-from 20% to 42% per year-resulting in an increase in number of donors from 26 to 128 per year (+390%). Despite wide variations among hospitals in the outcomes, our results seem very encouraging and express a positive impact of this model, suggesting that dissemination to other hospitals may increase the number of donors and transplants in our region.

    In recent years the generation rate of construction and demolition waste (C&D) has significantly augmented. The aim of this study was to assessed the quality and quantity of construction and demolition waste in Tehran (capital of Iran). Questionnaire methods were used for estimating the amount of generated C&D wastes national statistical data and typical waste generation data. In order to defining the composition of C&D waste, trucks were randomly selected and their wastes were separated and weighted. According to obtained results, about 82,646,051 m(3) of C&D waste (average 16,529,210 m(3) per year) were generated during 2011 to 2016 which only about 26% of them has been recycled. Mixing sand and cement, concrete, broken bricks and soil have the highest amount of the composition of C&D waste in Tehran that was 30, 19, 18 and 11%, respectively. Based on the results, about 2,784,158 t of the waste will generate in 2025 and this is approximately 122% higher than wastes generate in 2016. Based on MAPSA's data, 360 teams of personnel cruise and control the illegal disposals, but due to the expansion of Tehran this number of teams is inadequate and can't be effective in controlling the situation. In general, the overall condition of C&D waste management in Tehran seems undesirable and needs to be updated based on the experience of successful countries in this field.

    This paper refers to the management of the construction and demolition (C&D) waste since, according to the EU Waste Strategy, C&D waste is considered to be one of the priority waste streams and appropriate actions need to be taken with respect to its effective management. Initially, the paper presents the state-of-the-art of the problem of C&D waste, including the amount and composition of C&D waste in EU countries, differences in the characteristics of this waste stream depending on its origin, as well as collection and management practices that are applied. A methodology is described for the estimation of the quantities of the waste stream under examination, since in most cases quantitative primary data is not available. Next, the fundamentals for the development of an integrated scheme for the management of C&D waste are presented and discussed, such as appropriate demolition procedures and location of waste management (off-site waste management, on-site waste management, direct on-site recovery, centralized on-site recovery). Finally, taking into consideration all relevant parameters, alternative systems that could be applied for the management of the C&D waste are suggested.

  6. Demolish or refurbish – Environmental benefits of housing conservation

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available Climate change and energy efficiency are some of the most pressing issues facing China today. With its economic growth since 1978, the government has struggled to contain environmental damages and social unrest related to the economy’s rapid transformation. With the rapid growth in population and urbanization the demand for housing has escalated and traditional housing has been under threat of demolition to make way for new construction. Traditional housing is generally considered wasteful in its use of land and/or energy, and is often demolished for more intensive and more energy-efficient housing, despite the resulting loss of embodied energy and urban amenity. A research project was undertaken to study the environmental performance of traditional housing in Hangzhou. The project looks into analyzing and comparing embodied energy and CO2 for seven dwellings. In addition indoor climate data were recorded and collected in the form of hourly temperature and humidity readings for one year in six local houses and in a modern unit as a control for one year. The research results reveal that there is little difference in environmental performance between traditional and conventional modern construction and the value of conservation rather than demolition as a strategic development for the construction industry.

  10. High Flux Isotopes Reactor (HFIR) Cooling Towers Demolition Waste Management

    Energy Technology Data Exchange (ETDEWEB)

    Pudelek, R. E.; Gilbert, W. C.

    2002-02-26

    This paper describes the results of a joint initiative between Oak Ridge National Laboratory, operated by UT-Battelle, and Bechtel Jacobs Company, LLC (BJC) to characterize, package, transport, treat, and dispose of demolition waste from the High Flux Isotope Reactor (HFIR), Cooling Tower. The demolition and removal of waste from the site was the first critical step in the planned HFIR beryllium reflector replacement outage scheduled. The outage was scheduled to last a maximum of six months. Demolition and removal of the waste was critical because a new tower was to be constructed over the old concrete water basin. A detailed sampling and analysis plan was developed to characterize the hazardous and radiological constituents of the components of the Cooling Tower. Analyses were performed for Resource Conservation and Recovery Act (RCRA) heavy metals and semi-volatile constituents as defined by 40 CFR 261 and radiological parameters including gross alpha, gross beta, gross gamma, alpha-emitting isotopes and beta-emitting isotopes. Analysis of metals and semi-volatile constituents indicated no exceedances of regulatory limits. Analysis of radionuclides identified uranium and thorium and associated daughters. In addition 60Co, 99Tc, 226Rm, and 228Rm were identified. Most of the tower materials were determined to be low level radioactive waste. A small quantity was determined not to be radioactive, or could be decontaminated. The tower was dismantled October 2000 to January 2001 using a detailed step-by-step process to aid waste segregation and container loading. The volume of waste as packaged for treatment was approximately 1982 cubic meters (70,000 cubic feet). This volume was comprised of plastic ({approx}47%), wood ({approx}38%) and asbestos transite ({approx}14%). The remaining {approx}1% consisted of the fire protection piping (contaminated with lead-based paint) and incidental metal from conduit, nails and braces/supports, and sludge from the basin.

    The growing emphasis on ensuring the sustainability of animal agriculture is providing an impetus for the adoption of new approaches to structuring and conducting research. Sustainability is a complex topic involving many considerations related to the economic, social, and environmental impacts of production systems. Successfully addressing this topic requires multidisciplinary research as well as a high degree of communication with food system stakeholders to ensure that the research results contribute to informed decision making. In this paper, we provide an overview of a public-private partnership, the Coalition for Sustainable Egg Supply (CSES), which was formed to support research evaluating the sustainability of laying hen housing systems. Because of increasing public concerns about the behavioral restriction imposed on laying hens housed in conventional cages, the U.S. egg industry is faced with a need to transition to alternative systems. However, before the CSES project, there was limited information available about how this transition might affect trade-offs related to the sustainability of egg production. The goal of the CSES project was to provide this information by conducting holistic research on a commercial farm that had 3 different hen housing systems. The CSES members represented a variety of stakeholders, including food retailers and distributors, egg producers, universities, and governmental (USDA ARS) and nongovernmental organizations. The CSES was facilitated by a not-for-profit intermediary, the Center for Food Integrity, which was also responsible for communicating the research results to food system stakeholders, including via quantitative and qualitative consumer research. In this paper, we describe the structural aspects of the CSES that were responsible for the successful completion and dissemination of the research as well as the insights that were gained regarding multidisciplinary and multi-institutional collaboration, conducting

    Because current trends in hospital restructuring in North America, amalgamations and mergers, and the aging of health care facilities, the need to restructure physical buildings has become greater. Hospital construction carries with it risks to patients. One key concern is the risk of aspergillosis associated with hospital construction. Infection control practitioners must consider some key factors when addressing land excavation and building demolition, which differ in some ways from construction that occurs within a health care facility. The key factors to consider are project concept, risk assessment of patients, procedures and environment, air quality, routes of entry and egress, soil management, conducting inspections, contingency planning, housekeeping, and lines of cooperation and communication with various stakeholders. Considering these areas will help ensure that health care facility personnel and the workers have exercised diligence in patient care.

    An extensive debate on quantum non-demolition (QND) measurement, reviewed in Grangier et al (1998 Nature 396 537), finds that true QND measurements must have both non-classical state-preparation capability and non-classical information-damage tradeoff. Existing figures of merit for these non-classicality criteria require direct measurement of the signal variable and are thus difficult to apply to optically-probed material systems. Here we describe a method to demonstrate both criteria without need for to direct signal measurements. Using a covariance matrix formalism and a general noise model, we compute meter observables for QND measurement triples, which suffice to compute all QND figures of merit. The result will allow certified QND measurement of atomic spin ensembles using existing techniques.

    The objective of this article is to develop a computerised tool (software) that facilitates the analysis of strategies for waste management on construction sites through the use of indicators of construction and demolition waste generation. The development involved the following steps: knowledge acquisition, structuring the system, coding and system evaluation. The step of knowledge acquisition aims to provide subsidies for the representation of them through models. In the step of structuring the system, it was presented the structuring and formalisation of knowledge for the development of the system, and has two stages: the construction of the conceptual model and the subsequent instantiation of the model. The coding system aims to implement (code) the conceptual model developed in a model played by computer (digital). The results showed that the system is very useful and applicable in construction sites, helping to improve the quality of waste management, and creating a database that will support new research.

  18. Housing Assistance

    Full Text Available In Australia, an increasing number of households face problems of access to suitable housing in the private market. In response, the Federal and State Governments share responsibility for providing housing assistance to these, mainly low-income, households. A broad range of policy instruments are used to provide and maintain housing assistance across all housing tenures, for example, assisting entry into homeownership, providing affordability assistance in the private rental market, and the provision of socially owned and managed housing options. Underlying each of these interventions is the premise that secure, affordable, and appropriate housing provides not only shelter but also a number of nonshelter benefits to individuals and their households. Although the nonshelter outcomes of housing are well acknowledged in Australia, the understanding of the nonshelter outcomes of housing assistance is less clear. This paper explores nonshelter outcomes of three of the major forms of housing assistance provided by Australian governments—low-income mortgage assistance, social housing, and private rent assistance. It is based upon analysis of a survey of 1,353 low-income recipients of housing assistance, and specifically measures the formulation of health and well-being, financial stress, and housing satisfaction outcomes across these three assistance types. We find clear evidence that health, finance, and housing satisfaction outcomes are associated with quite different factors for individuals in these three major housing assistance types.

Methods A cluster randomized design with 12 housing sites as the primary sampling units was used: 6 sites were assigned to a "Peer-led plus Screening Access" (PL condition, and 6 were assigned to "Screening Access only" (SCR condition. Study-related outcomes were CRC screening, physical activity (measured as mean steps/day, and multivitamin use. Results At baseline (unweighted sample size = 1554, two-thirds self-reported that they were current with screening recommendations for CRC (corrected for medical records validation, prevalence was 52%, with half having received a colonoscopy (54%; 96% had health insurance. Mean steps per day was 5648 (se mean = 224, and on average 28% of the sample reported regular multivitamin use. Residents reported high levels of social support [mean = 4.40 (se = .03] and moderately extensive social networks [mean = 2.66 (se = .02]. Conclusion Few studies have conducted community-based studies in public housing communities; these data suggest areas for improvement and future opportunities for intervention development and dissemination. Findings from the randomized trial will determine the effectiveness of the intervention on our health-related outcomes as well as inform future avenues of research.

    Full Text Available The waste generated from construction and demolition sites is considered one of the most irritating problems in Egypt. In the last 10 years some effort has been made toward solving this problem, the most outstanding is the newly issued Egyptian rating system “Green Pyramids Rating System”. It emphasizes on waste management and particularly “site provision and environment” which contributes to 75% of the management category score. However the traditional practice which is limited to dumping all the generated waste is still dominating. The absence of sustainable practices in construction sector in Egypt led to the lack in financial and environmental data. From strategic perspective, the research aims at developing a detailed procedure to evaluate two construction and demolition waste management approaches by means of Decision Matrix technique. A detailed study is introduced for the two approaches; for each approach a flow chart is developed to demonstrate its lifecycle, as well as the cost break down structure and the different stakeholders’ roles. A penetration discussion of the pros and cons for each approach was developed accordingly and came out with sixteen influencing attributes for both approaches. The previous steps paved the ground to construct a Decision Matrix to decide on one of the approaches from a strategic environmentally oriented perspective. The study relied on the detailed and deep demonstration of the two approaches to justify the assigned weight for attributes and scores for corresponding approach. From a strategic perspective, the decision came out in favor of the more environmentally friendly approach.

    Based on the concept of cultural capital, this study explores the relationship between habitual behaviors of individuals regarding their past accumulation of such capital and current responses to a scientific institute's public outreach activity. At an open house held at the Institute for Molecular Science (IMS), anonymous questionnaires were distributed among 1,350 visitors and collected from 785 of them (collection rate = 58.1%). The results, measuring the past five to six years, showed that the respondents accumulated cultural capital through participation in scientific activities as well as in activities involving art, music, and literature. Given these quantified values, correlations between citizens' levels of accumulated cultural capital and their current scientific consumption behavior were studied. A statistical analysis of the two components of cultural capital (science and technology/art and literature) showed that people's accumulated scientific capital influenced their current behavior and revealed a correlation between the two components.

    Demolition waste materials are one of the major industrial waste deposits in many countries and represent an important quantity of potential resources that are not exploited, because the major part of these wastes go to landfill. Indeed, recycling or recovery of demolition waste can reduce the need of primary natural resources. This article gives indicators and a method to analyse demolition waste management with regard to the use of resources contained in these wastes. Demolition wastes are characterized by their contents in energy and raw materials. This content is quantified on the basis of the sum of energy and raw materials necessary for the construction of the building considering the non-renewable character of materials contained in wastes. In fact, this content represents the environmental investment which was necessary to construct the building. An energy balance and a mass balance, with this concept of ;raw material and energy' content, can allow a strategy of waste management to be determined in order to salvage the most important parts of energy and raw materials contained in demolition waste, and so identify the strategy which permits a maximum fraction of the initial environmental investment to be saved. Five waste management scenarios concerning building demolition were assessed with this method and these indicators, and the results are presented in this article.

    In 2007, over 24 million tons of Construction and Demolition (C&D) wastes were generated in Hong Kong. Since the local landfills will be saturated in about 6 years, it is important to find a viable way to reuse these waste materials as to alleviate the demand on public fill capacity. In order to tackle the problem, the Hong Kong government has set up a temporary recycling facility in Hong Kong in 2002 for producing different sizes of recycled aggregate for use in various construction materials. The Hong Kong Polytechnic University has been studying the feasible use of recycled aggregates in Hong Kong for a number of years. A substantial amount of experimental results on the properties of recycled aggregates and the effect of recycled aggregates on the properties of concrete and other construction products (e. G. Concrete blocks and granular sub-base) has been published. In this paper, the experience of Hong Kong in using recycled aggregates are summarized and a set of quality control guidelines proposed for governing the use of recycled aggregates in Hong Kong is introduced. The experience and guidelines may also be useful for the recycling of waste materials derived from the recent Sichuan earthquake in China.

    Hexabromocyclododecane (HBCDD), as one of the most widely used brominated flame retardants (BFRs), is of great concern globally because of its persistence in the environment and negative impacts on humans and animals. HBCDD has been mainly used in flame-retarded expanded (EPS) and extruded (XPS) polystyrene foams for insulation in the construction industry. Most of these products will become a part of the construction and demolition (C&D) waste at the end of their life cycle (30-50 years) which is typically disposed of into landfills or incineration. However, the recycling of this material takes quite a low share compared with landfill and incineration. Consequently, high environmental risks will exist in these disposal approaches due to the HBCDD in C&D waste. Currently, XPS or EPS products containing HBCDD in the construction industry have not reached the end of their life cycle in most countries. Relatively little attention has been paid to this emergency issue by either the government or public. Furthermore, C&D waste is most likely disposed of by direct dumping, simple stacking, or open burning in developing countries. Therefore, this paper highlights the global environmental risks of HBCDD from C&D waste. Areas of research for key problems of HBCDD contained in C&D waste are suggested to help control and finally eliminate the impact.

    Selective demolition practices have not yet become popular in our country. Unlike conventional demolition practices, selective demolition helps to increase the amount of components to be reused or materials to be recycled. Thus, the percentage of demolition waste deposited in landfills can be reduced, and the production of recycled materials with optimum quality is fostered. Taking the case study of selective demolition carried out in the municipally of Lasarte-Oria (Basque Country-Spain) as its basis, this paper presents an economic and environmental analysis of the same. Likewise, the economic costs deriving from selective demolition are compared with analogous costs from conventional demolition with an aim to establishing the ideal frame supporting economically feasible selective demolition.

    In Republic of Korea, construction and demolition (C&D) waste accounts for 49.9% of the total waste. In the present work, the mineralogical composition, the concentrations of 11 heavy metals, 19 PAH, and 7 polychlorinated biphenyl (PCB) congeners present in the 6 broad category (9 subcategories) of C&D hazardous waste were discussed along with their leaching characteristics. In concrete/mixed cement waste, the concentrations of As, Cr(6+), Hg, and Zn were in the range of 1.76-7.86, ND-1.63, 0.026-0.047, and 110.90-280.17 mg/kg, respectively. The asphalt waste sample A1 possessed relatively high concentrations of phenanthrene, fluoranthene, pyrene, benz(a)anthracene, benzo(a)pyrene, and indeno(1,2,3-cd)pyrene comparing to the other samples and it contains 0.08-0.1% of coal tar. Hazardous nature of the C&D wastes greatly depends on the source of the collection. Zn concentration was above 1000 mg/kg for road asphalt waste samples A4 and A5. Total PCB concentration were high in the soil waste sample S1 (130 μg/kg) as it was the excavated soil obtained from the premises of an oil station. Leaching of As, Ba, CN(-), and F(-) were observed in most of the C&D waste samples.

    There is an increasing pressure on the construction industry to reduce costs and improve the quality of our environment. The fact is that both of these goals can be achieved at the same time. Although construction and demolition (C&D) constitutes a major source of waste in terms of volume and weight, its management and recycling efforts have not yet seen the light in Kuwait. This study focuses on recycling efforts leading to the minimization of the total C&D waste that is currently landfilled in Kuwait. This paper presents the current status of C&D waste disposal system in Kuwait and identifies the potential problems to the environment, people and economy. Then, it investigates alternative solutions to manage and control this major type of waste in an economically efficient and environmentally safe manner. Next, the paper describes the feasibility of establishing a C&D waste recycling facility in Kuwait. It concludes by highlighting the major benefits and bottleneck problems with such a recycling facility.

    Even though construction and demolition waste (CDW) is the bulkiest waste stream, its estimation and composition in specific regions still faces major difficulties. Therefore new methods are required especially when it comes to make predictions limited to small areas, such as counties. This paper proposes one such method, which makes use of data collected from real demolition works and statistical information on the geographical area under study. Based on a correlation analysis between the demolition waste estimates and indicators such as population density, buildings ageing index, buildings density and land occupation type, relationships are established that can be used to determine demolition waste outputs in a given area. The derived models are presented and explained. This methodology is independent from the specific region with which it is exemplified (the Lisbon Metropolitan Area) and can therefore be applied to any region of the world, from the country to the county level. Generation of demolition waste data at the county level is the basis of the design of a systemic model for CDW management in a region. Future developments proposed include a mixed-integer linear programming formulation of such recycling network.

    African-American youth are disproportionately affected by parental incarceration and the consequences of parental substance use. Many adapt to the loss of their parents to prison or drug addiction by engaging in sex-risk behavior, particularly the sex trade. These youth may engage in this risky behavior for a number of reasons. Although previous research has examined this issue, most of these studies have focused on runaway or street youth or youth in international settings. Empirical evidence on correlates of trading sex for money among urban African-American youth is practically missing. Using a sample of 192 African-American youth living in urban public housing, this paper attempts to rectify this gap in knowledge by assessing how individual and parental factors are related to the likelihood of a youth trading sex for money. The sample for this study reported a mean age of 19; 28 % reported having traded sex for money; 30 % had a father currently in prison; and 7 % reported having a mother currently in prison. Maternal incarceration and paternal substance use were associated with a higher likelihood of trading sex for money. Given the potential health risks associated with trading sex for money, understanding correlates of this behavior has important implications for the health of this vulnerable population of youth and urban health in general.

  5. Coal and wood fuel for electricity production: An environmentally sound solution for waste and demolition wood

    Energy Technology Data Exchange (ETDEWEB)

    1997-12-31

    Waste wood from primary wood processing and demolition presents both a problem and a potential. If disposed in landfills, it consumes large volumes and decays, producing CH{sub 4}, CO{sub 2} and other greenhouse gases. As an energy source used in a coal fired power plant it reduces the consumption of fossil fuels reducing the greenhouse effect significantly. Additional advantages are a reduction of the ash volume and the SO{sub 2} and NO{sub x} emissions. The waste wood requires collection, storage, processing and burning. This paper describes a unique project which is carried out in the Netherlands at EPON`s Gelderland Power Plant (635 MW{sub e}) where 60 000 tonnes of waste and demolition wood will be used annually. Special emphasis is given to the processing of the powdered wood fuel. Therefore, most waste and demolition wood can be converted from an environmental liability to an environmental and economic asset. (author)

    According to the Life Cycle Assessment in Building and Construction: State-of-the-Art Report (2003), the dismantling and demolition stage of the building life cycle is only sometimes included in the Life Cycle Inventory (LCI) when doing Life Cycle Assessments (LCA). The reason that it is less...... inventoried in a traditional LCA maybe because this stage is expected to have a negligible environmental impact comparing to other stages in the life cycle of the buildings. When doing a life cycle sustainability assessment considering not only environmental but also economic and social impacts, the impacts...... of the labor-intensive dismantling and demolition stage may not be possible to disregard anymore, due to the related process costs, health and safety of workers and the influence on the quality of the demolition materials, determining their suitability for high grade recycling.

    A post-demolition modeling analysis is conducted that compares during-demolition atmospheric concentration monitoring results with modeling results based on the actual meteorological conditions during the demolition activities. The 224-U and 224-UA Buildings that were located in the U-Plant UO3 complex in the 200 West Area of the Hanford Site were demolished during the summer of 2010. These facilities converted uranyl nitrate hexahydrate (UNH), a product of Hanford’s Plutonium-Uranium Extraction (PUREX) Plant, into uranium trioxide (UO3). This report is an addendum to a pre-demolition emission analysis and air dispersion modeling effort that was conducted for proposed demolition activities for these structures.

    2016-07-01

    Demolition of buildings produce large quantities of particulate matter (PM) that could be inhaled by on-site workers and people living in the neighbourhood, but studies assessing ambient exposure at the real-world demolition sites are limited. We measured concentrations of PM10 (≤10 μm), PM2.5 (≤2.5 μm) and PM1 (≤1 μm) along with local meteorology for 54 working hours over the demolition period. The measurements were carried out at (i) a fixed-site in the downwind of demolished building, (ii) around the site during demolition operation through mobile monitoring, (iii) different distances away from the demolition site through sequential monitoring, and (iv) inside an excavator vehicle cabin and on-site temporary office for engineers. Position of the PM instrument was continuously recorded using a Global Positioning System on a second basis during mobile measurements. Fraction of coarse particles (PM2.5-10) contributed 89 (with mean particle mass concentration, PMC ≈ 133 ± 17 μg m-3), 83 (100 ± 29 μg m-3), and 70% (59 ± 12 μg m-3) of total PMC during the fixed-site, mobile monitoring and sequential measurements, respectively, compared with only 50% (mean 12 ± 6 μg m-3) during the background measurements. The corresponding values for fine particles (PM2.5) were 11, 17 and 30% compared with 50% during background, showing a much greater release of coarse particles during demolition. The openair package in R and map source software (ArcGIS) were used to assess spatial variation of PMCs in downwind and upwind of the demolition site. A modified box model was developed to determine the emission factors, which were 210, 73 and 24 μg m-2 s-1 for PM10, PM2.5 and PM1, respectively. The average respiratory deposited doses to coarse (and fine) particles inside the excavator cabin and on-site temporary office increased by 57- (and 5-) and 13- (and 2-) times compared with the local background level, respectively.

    We have studied the possibility of a single-shot non-demolition measurement of a superconducting qubit using a microstrip SQUID amplifier (MSA). The Johnson noise generated by all resistors in the MSA is taken into consideration. We show that a single-shot non-demolition measurement is possible with six photons in the measurement resonator. For a phase qubit inductively coupled to a measurement resonator we have obtained the expression for the mutual inductance required for measurement of the qubit state.

    Lebanon's very high population density has been increasing since the end of the war in the early 1990s reaching 416.36 people per square kilometer. Furthermore, the influx of refugees from conflicts in the region has increased the resident population significantly. All these are exerting pressure on the country's natural resources, pushing the Lebanese to convert more forest and agricultural land into roads, buildings and houses. This has led to a building boom and rapid urbanization which in turn has created a demand for construction material - mainly rock, gravel, sand, etc. nearly all of which were locally acquired through quarrying to the tune of three million cubic meters annually. This boom has been followed by a war with Israel in 2006 which resulted in thousands of tonnes of debris. The increase in population has also led to an increase in solid waste generation with 1.57 million tonnes of solid waste generated in Lebanon per year. The combination of construction, demolition and excavation (CDE) waste along with the increase in solid waste generation has put a major stress on the country and on the management of its solid waste problem. Compounding this problem are the issues of quarries closure and rehabilitation and a decrease in forest and vegetative cover. The on-going research reported in this paper aims to provide an integrated solution to the stated problem by developing a "soil mix" derived from a mélange of the organic matter of the solid waste (compost), the CDE waste, and soil. In this mix, native and indicator plants are planted (in pots) from which the most productive mix will be selected for further testing at field level in later experiments. The plant species used are Matiolla, a native Lebanese plant and Zea mays, which is commonly known used as an indicator plant due to its sensitivity to environmental conditions. To ensure sustainability and environmental friendliness of the mix, its physical and chemical characteristics are monitored

    This paper studies the impact of the urban public service on the housing prices, using the Tiebout theory and the panel data threshold regression. The results show that there is an obvious nonlinear threshold relationship between the level of public service and the housing prices. With the improvement of the level of pubic service, the impact on housing prices also increases gradually. The imbalance of urban public resource allocation is a main reason of some urban housing prices grow fast. So it is put forward that the real estate regulation is system engineering. The tax policy and fiscal transfer policy pegged to the level of public service should be explored.%基于Tiebout理论,采用构建基础理论模型及面板门限回归方法,检验城市公共服务供给水平对房价变动的影响。结果表明,公共服务供给与房价之间存在显著的非线性门限关系,随着公共服务供给水平的增加,其对房价影响也逐步增大,城市间公共资源配置失衡是造成一些城市房价分化的主要原因。据此提出房地产市场调控是一个系统工程,应探索与公共服务水平挂钩的房地产税收政策、财政转移支付政策等。

    Life cycle assessment (LCA) modelling of construction and demolition waste (C&DW) management was carried out. The functional unit was management of 1 Mg mineral, source separated C&DW, which is either utilised in road construction as a substitute for natural aggregates, or landfilled. The assessed environmental impacts included both non-toxic and toxic impact categories. The scenarios comprised all stages of the end-of-life management of C&DW, until final disposal of all residues. Leaching of inorganic contaminants was included, as was the production of natural aggregates, which was avoided because of the use of C&DW. Typical uncertainties related to contaminant leaching were addressed. For most impact categories, utilisation of C&DW in road construction was preferable to landfilling; however, for most categories, utilisation resulted in net environmental burdens. Transportation represented the most important contribution for most nontoxic impacts, accounting for 60-95 per cent of these impacts. Capital goods contributed with negligible impacts. Leaching played a critical role for the toxic categories, where landfilling had lower impacts than utilisation because of the lower levels of leachate per ton of C&DW reaching the groundwater over a 100-year perspective. Leaching of oxyanions (As, V and Sb) was critical with respect to leaching. Typical experimental uncertainties in leaching data did not have a pivotal influence on the results; however, accounting for Cr immobilisation in soils as part of the impact assessment was critical for modelling the leaching impacts. Compared with the overall life cycle of building and construction materials, leaching emissions were shown to be potentially significant for toxicity impacts, compared with contributions from production of the same materials, showing that end-of-life impacts and leaching should not be disregarded when assessing environmental impacts from construction products and materials.

    Full Text Available Aims: The aim of this study was the investigation of musculoskeletal disorders risk factors among building demolition workers. Materials and Methods: Posture, activity, tools, and handling (PATH method as a work sampling method was applied to record the postures, activities, and handling of building demolition workers in four tasks. The percentage of working time is reported for each item to compare the risk factors in tasks. Nordic musculoskeletal questionnaire also was used to study the prevalence of musculoskeletal disorders over 12 months. Results: Trunk, leg(s, and arm(s postures differed significantly among tasks. Neutral arm posture and non-neutral leg(s and trunk postures were observed frequently. Manual materials handling (MMH activities are distributed differently among tasks. Moving was the most observed (35% and carrying was the less observed (11.8% MMH activity. Gross grasp was the most observed (78.5% hand activity in building demolition workers. The most observed weight category was 0 kg≤load<5 kg. Low back had the highest prevalence of MSDs symptoms (91.1% and hip had the lowest prevalence of symptoms (6.7%. Conclusions: PATH is applicable to building demolition process. Ergonomic intervention is necessary in high prevalence body regions such as lower back and wrist to decrease the symptoms. With respect to the results of PATH method, ergonomic interventions for trunk and leg(s are necessary in all tasks, but only task #3 is in the priority of arm(s intervention.

    Mixed waste products are generated in the process of irrelevant industrial projects’ removal if conventional techniques of their demolition and dismantling are applied. In Russia the number of unused chemical industry facilities including structures with high rate of wear is growing. In removing industrial buildings and production shops it is used conventional techniques of demolition and dismantling in the process of which mixed waste products are generated. The presence of hazardous chemicals in these wastes makes difficulties for their use and leads to the increasing volume of unutilized residues. In the process of chemical industry facilities’ removal this fact takes on special significance as a high level of hazardous chemicals in the waste composition demands for the realization of unprofitable measures aimed at ensuring environmental and industrial safety. The proposed strategy of managing waste originated from the demolition and dismantling of chemical industry facilities is based on the methodology of industrial metabolism which allows identifying separate material flows of recycled, harmful and ballast components, performing separate collection of components during removal and taking necessary preventive measures. This strategy has been tested on the aniline synthesis plant being in the process of removal. As a result, a flow of 10 wt. %, subjected to decontamination, was isolated from the total volume of construction and demolition waste (C&D waste). The considered approach allowed using the resource potential of more than 80wt. % of waste and minimizing the disposed waste volume.

    Construction and demolition waste continues to sharply increase in step with the economic growth of less developed countries. Though the construction industry is large, it is composed of small firms with individual waste management practices, often leading to the deleterious environmental outcomes. Quantifying construction and demolition waste generation allows policy makers and stakeholders to understand the true internal and external costs of construction, providing a necessary foundation for waste management planning that may overcome deleterious environmental outcomes and may be both economically and environmentally optimal. This study offers a theoretical method for estimating the construction and demolition project waste generation rate by utilising available data, including waste disposal truck size and number, and waste volume and composition. This method is proposed as a less burdensome and more broadly applicable alternative, in contrast to waste estimation by on-site hand sorting and weighing. The developed method is applied to 11 projects across Malaysia as the case study. This study quantifies waste generation rate and illustrates the construction method in influencing the waste generation rate, estimating that the conventional construction method has a waste generation rate of 9.88 t 100 m(-2), the mixed-construction method has a waste generation rate of 3.29 t 100 m(-2), and demolition projects have a waste generation rate of 104.28 t 100 m(-2).

    2017-05-01

    Demolition waste consisting of cement paste, lightweight concrete and bricks is a worthless material generated by a growing city. However, research suggests that it may be applied as an alternative heavy metal immobilising agent. The diverse characteristics of demolition waste were examined. Cadmium was selected as there presentative heavy metal to investigate demolition waste adsorption capacity. The solid-liquid distribution coefficients (Kd) were observed. The adsorption isotherms were applied to investigate adsorption characteristics. Carbon content in the demolition waste materials was low and mainly in inorganic form. Cement paste and lightweight concrete had an alkaline pH with very high acid neutralising capacity (ANC). The surface area and cation exchange capacity (CEC) of these materials were low. Cement paste possessed the highest pH, ANC, CEC and surface area, with the highest Kd; however, its specific surface area and CEC were low compared to activated carbon and organic material. The adsorption isotherms indicated surface heterogeneity with favourable conditions for adsorption and the mean free energy suggested physisorption with multilayer formation. The Kd values of the tested materials were comparable to soil which was not effective in immobilising heavy metal via adsorption mechanisms. However, the high pH and ANC of cement paste and lightweight concrete can improve the heavy metal adsorption capacity of soil and soil ANC that help prevents and controls leaching by heavy metals.

    民间资本不愿意投资公租房项目的主要原因是项目投资回报率低。因此,为了在公租房中以BOT模式引入民间资本参与投资建设,就必须要建立相应的投资激励机制。考虑到税费优惠是最常用的投资激励手段之一,本文在建立公租房项目收益函数的基础上,以算例量化分析税费优惠的激励强度。%The private capital is not willing to invest in the construction of public rental housing primarily due to the low capital return ratio.Therefore,it is necessary to establish a kind of incentive mechanism,in order to induce private capital into the construction of public rental housing.In view of taxes and fees concession is the most com-monly used method in investment incitement,this paper establishes a profit function on public rental housing,makes quantitative analysis of the incentive intensity of taxes and fees concession by a case.

    Full Text Available Exposure to traffic-generated ultrafine particles (UFP; particles <100 nm is likely a risk factor for cardiovascular disease. We conducted a trial of high-efficiency particulate arrestance (HEPA filtration in public housing near a highway. Twenty residents in 19 apartments living <200 m from the highway participated in a randomized, double-blind crossover trial. A HEPA filter unit and a particle counter (measuring particle number concentration (PNC, a proxy for UFP were installed in living rooms. Participants were exposed to filtered air for 21 days and unfiltered air for 21 days. Blood samples were collected and blood pressure measured at days 0, 21 and 42 after a 12-hour fasting period. Plasma was analyzed for high sensitivity C-reactive protein (hsCRP, interleukin-6 (IL-6, tumor necrosis factor alpha-receptor II (TNF-RII and fibrinogen. PNC reductions ranging from 21% to 68% were recorded in 15 of the apartments. We observed no significant differences in blood pressure or three of the four biomarkers (hsCRP, fibrinogen, and TNF-RII measured in participants after 21-day exposure to HEPA-filtered air compared to measurements after 21-day exposure to sham-filtered air. In contrast, IL-6 concentrations were significantly higher following HEPA filtration (0.668 pg/mL; CI = 0.465–0.959 compared to sham filtration. Likewise, PNC adjusted for time activity were associated with increasing IL-6 in 14- and 21-day moving averages, and PNC was associated with decreasing blood pressure in Lags 0, 1 and 2, and in a 3-day moving average. These negative associations were unexpected and could be due to a combination of factors including exposure misclassification, unsuccessful randomization (i.e., IL-6 and use of anti-inflammatory medicines, or uncontrolled confounding. Studies with greater reduction in UFP levels and larger sample sizes are needed. There also needs to be more complete assessment of resident time activity and of outdoor vs. indoor source

    To examine the cross-sectional association between illicit sales of tobacco to minors, Washington DC tobacco outlet advertising practices, retail store type, the demographic make-up of the area surrounding each outlet, and the proximity of each outlet to high schools, recreational parks and public housing. Seven hundred and fifty tobacco outlets in the DC area, n=347 of which were randomly selected for inspection by the Synar Inspection Program in 2009-2010. The presence of tobacco advertisements on the interior and exterior of each outlet, and illicit tobacco sales to Synar Inspection Program youth volunteers. The presence of tobacco advertisements on the exterior of gas stations was much greater than on other retail store types (OR=6.68; 95% CI 4.05 to 11.01), as was the absence of any advertisements at bars or restaurants that sold tobacco (OR=0.33; 95% CI 0.22 to 0.52). Exterior tobacco advertisements were also more likely in predominantly African-American areas of the city (OR=3.11; 95% CI 2.28 to 4.25), and particularly likely on storefronts located closer to parks (OR=1.87; 95% CI 1.06 to 3.28). Illicit sales to minors were more common at gas stations (OR=3.01; 95% CI 1.5 to 6.3), outlets that displayed exterior tobacco advertisements closer to parks (OR=3.36; 95% CI 1.38 to 8.21), and outlets located closer to high schools in majority African-American block groups (OR=1.29; 95% CI 1.07 to 1.58). Findings demonstrate that while illicit tobacco sales to minors are occurring at acceptably low rates by Synar standards, illicit sales vary considerably by retail store type, advertising approach and proximity to high schools, parks and African-American residential areas. Future work may help inform regulatory efforts to reduce youth access at the neighbourhood, city, state and national levels. Published by the BMJ Publishing Group Limited.

    Residents in localities throughout the world voluntarily participate in the routine recycling of household wastes, such as paper, metals, and plastics containers. But when a house in their neighborhood gets built or torn down, most of the debris – including wood waste – gets landfilled. Such a waste of material suggests that there are opportunities to add value to these under-utilized resources. The great variability, as well as contamination, pose major challenges. It is recommended that rec...

  18. The impact of housing policies and housing markets on ethnic spatial segregation

    2015-01-01

    This paper examines how ethnic segregation is connected to an ethnic division of the housing market and a spatial separation of different housing tenures in four Nordic cities. Explanations for the differences across the cities are found by comparing housing markets and housing policies....... The housing markets are in all four cities ethnically segmented with high concentrations of immigrants in some forms of tenures (especially social/public housing) and low concentrations in others. We further discuss the reasons for the observed pattern. The paper shows that the spatial distribution...... housing, while co-operative housing is crucial in the fourth. It is also shown that a policy of neighbourhood tenure mix in one of the cities has resulted in a relatively low degree of segregation in spite of high concentrations of immigrants in social/public housing....

    2016-08-01

    Full Text Available Within the scope of urban transformation new demolition techniques are seeked due to the old and damaged buildings to be demolished. Considering the advantages, controlled structure destruction by explosives is a remarkable technique that is applied successfully in abroad countries for years.In this study, the controlled demolition of Edirne Kapıkule Customs Building by using explosives was done. For this purpose, the building plan is determined by using tape measure and modelled in PC. Building’s material properties are found as a result of laboratory studies and information about building’s static balance is obtained. To determine charge, trial blasting on columns are done. From these results appropriate firing sequence is determined. The determined firing sequence is performed on the model, generated by using a finite element analyzing software. The behavior of the building, loads on columns during the demolition, are determined. The loads on columns are compared with the column’s carrying capacity. As a result of this, the deformation of the building after demolition is over, is foreseen. After the operation, it could be said that demolition achieved its goal. But the predicted deformation didn’t occur on the structure elements, explosives weren’t placed in. The reasons for this were examined.When the comparison of demolition by using machine cost and demolition by using explosives cost, the demolition by using machine is more advantageous because of less number of floors. It ıs observed that, measured vibration values  are not adequate  to cause damage on reinforced concrete buildings.

    1985-01-01

    Discharges of radionuclides from the British Nuclear Fuel plc (BNFL) reprocessing plant at Sellafield in Cumbria have led to elevated concentrations radionuclides in the local environment. The major routes of exposure of the public are kept under review by the appropriate Government departments and monitoring is carried out both by the departments and by BNFL itself. Recently, there has been increasing public concern about general environmental contamination resulting from the discharges and, in particular, about possible exposure of members of the public by routes not previously investigated in detail. One such postulated route of exposure that has attracted the interest of the public, the press and Parliament arises from the presence of radionuclides within houses. In view of this obvious and widespread concern, the Board has undertaken a sampling programme in a few communities in Cumbria to assess the radiological significance of this source of exposure. From the results of our study, we conclude that, alt...

    This project was conducted to evaluate buildings and facilities remaining in the Washington Closure Hanford (WCH) deactivation, decontamination, decommissioning, and demolition schedule for bat roost sites. The project began in spring of 2009 and was concluded in spring of 2011. A total of 196 buildings and facilities were evaluated for the presence of bat roosting sites. The schedule for the project was prioritized to accommodate the demolition schedule. As the surveys were completed, the results were provided to the project managers to facilitate planning and project completion. The surveys took place in the 300 Area, 400 Area, 100-H, 100-D, 100-N, and 100-B/C Area. This report is the culmination of all the bat surveys and summarizes the findings by area and includes recommended mitigation actions where bat roosts were found.

    2008-12-08

    We propose an alternative method for the quantum non-demolition measurement of photon numbers wherein weak cross-Kerr nonlinearities are to be used. The usual approach to quantum non-demolition measurements of quantum number involves encoding the photon number, through a cross-Kerr interaction, into a phase shift of a probe coherent state which is then detected through balanced homodyning. Weak nonlinearities produce small phase shifts which are difficult to detect and distinguish. In the method we propose, unbalanced homodyning acts as a displacement operator on the probe beam coherent state such that the cross-Kerr interaction encodes the photon number into the amplitude of a new coherent state. The value of the photon number can be determined by inefficient photon counting on the new coherent state. Our proposed method requires fewer resources than does the usual approach.

    A simple and efficient quantum non-demolition measurement (QND) scheme is proposed in which the arrival of a signal photon is detected without affecting the qubit state. The proposed QND scheme functions even if the ancillary photon is replaced with weak light composed of vacuum and one-photon states. Although the detection scheme is designed for entanglement sharing applications, it is also suitable for general purification of a single photon state.

    Coelho, André; de Brito, Jorge

    2012-03-01

    The purpose of this study is to quantify comparable environmental impacts within a Life Cycle Analysis (LCA) perspective, for buildings in which the first (Materials) and last (End of Life) life cycle stages are adjusted to several waste/material management options. Unlike most LCAs, the approach is "top-down" rather than "bottom-up", which usually involves large amounts of data and the use of specific software applications. This approach is considered appropriate for a limited but expedient LCA designed to compare the environmental impacts of different life cycle options. Present results, based on real buildings measurements and demolition contractor activities, show that shallow, superficial, selective demolition may not result in reduced environmental impacts. Calculations actually show an increase (generally less than 5%) in most impact categories for the Materials and End of Life stages because of extra transportation needs. However, core material separation in demolition operations and its recycling and/or reuse does bring environmental benefits. A reduction of around 77% has been estimated in the climate change impact category, 57% in acidification potential and 81% in the summer smog impact (for the life cycle stages referred).

  20. RECOVERY AND REUSE OF FINE AGGREGATE FROM DEBRIS OF BUILDING DEMOLITION

    Directory of Open Access Journals (Sweden)

    2015-02-01

    Full Text Available Demolition of unsafe buildings and structures requiring extensive modifications is more common now a days. Almost 30% of new constructions are coming up on the demolition site. Handling of demolition debris has become a challenging issue in all the developing countries including India. The growth rate in the construction sector is 1.5 times in 5 years. While the demand for aggregates is increasing day-by-day, the natural resources like sand, gravel etc. are decreasing around the world. The need for the recycle of aggregate recovered from the debris is the need of the hour to meet the rising demand. Various studies have been reported on the subject. The present study reports the developed empirical relations between the area of the building and different items of materials in the debris for the estimation of quantity generation. Experimental results on the strength of concrete for different proportions of replacement of fine aggregate recovered from the debris are presented. The study results encourage the use of fine aggregate recycle in concrete.

    Proximity to public housing projects has a small but statistically significant effect on the incidence of violent crime. However, adjacency to public housing is a weak predictor of violent crime once the socioeconomic and housing characteristics of the adjacent blocks are taken into account. (Author/GC)

    Located in Area 25 of the Nevada Test Site (NTS), the Test Cell A (TCA) Facility (Figure 1) was used in the early to mid-1960s for testing of nuclear rocket engines, as part of the Nuclear Rocket Development Program, to further space travel. Nuclear rocket testing resulted in the activation of materials around the reactors and the release of fission products and fuel particles. The TCA facility, known as Corrective Action Unit 115, was decontaminated and decommissioned (D&D) from December 2004 to July 2005 using the Streamlined Approach for Environmental Restoration (SAFER) process, under the Federal Facility Agreement and Consent Order. The SAFER process allows environmental remediation and facility closure activities (i.e., decommissioning) to occur simultaneously, provided technical decisions are made by an experienced decision maker within the site conceptual site model. Facility closure involved a seven-step decommissioning strategy. First, preliminary investigation activities were performed, including review of process knowledge documentation, targeted facility radiological and hazardous material surveys, concrete core drilling and analysis, shield wall radiological characterization, and discrete sampling, which proved to be very useful and cost-effective in subsequent decommissioning planning and execution and worker safety. Second, site setup and mobilization of equipment and personnel were completed. Third, early removal of hazardous materials, including asbestos, lead, cadmium, and oil, was performed ensuring worker safety during more invasive demolition activities. Process piping was to be verified void of contents. Electrical systems were de-energized and other systems were rendered free of residual energy. Fourth, areas of high radiological contamination were decontaminated using multiple methods. Contamination levels varied across the facility. Fixed beta/gamma contamination levels ranged up to 2 million disintegrations per minute (dpm)/100

    Highlights: ► We developed a waste estimation system leveraging the BIM technology. ► The system can calculate waste disposal charging fee and pick-up truck demand. ► We presented an example scenario demonstrating this system. ► Automatic, time-saving and wide applicability are the features of the system. - Abstract: Due to the rising worldwide awareness of green environment, both government and contractors have to consider effective construction and demolition (C and D) waste management practices. The last two decades have witnessed the growing importance of demolition and renovation (D and R) works and the growing amount of D and R waste disposed to landfills every day, especially in developed cities like Hong Kong. Quantitative waste prediction is crucial for waste management. It can enable contractors to pinpoint critical waste generation processes and to plan waste control strategies. In addition, waste estimation could also facilitate some government waste management policies, such as the waste disposal charging scheme in Hong Kong. Currently, tools that can accurately and conveniently estimate the amount of waste from construction, renovation, and demolition projects are lacking. In the light of this research gap, this paper presents a building information modeling (BIM) based system that we have developed for estimation and planning of D and R waste. BIM allows multi-disciplinary information to be superimposed within one digital building model. Our system can extract material and volume information through the BIM model and integrate the information for detailed waste estimation and planning. Waste recycling and reuse are also considered in our system. Extracted material information can be provided to recyclers before demolition or renovation to make recycling stage more cooperative and more efficient. Pick-up truck requirements and waste disposal charging fee for different waste facilities will also be predicted through our system. The results

    The outcomes of climate science are inherently rife with discussions of dire consequences for humans that leave many listeners feeling helpless and hopeless. We have found that a focus on clean energy solutions, without reference to dirty energy, substantially reduces (may even eliminate) the negativity associated with sea level rise, extreme weather and other climate change presentations. US audiences respond well to discussion of California's clean energy transformation with solar, wind, geothermal and water power together now approaching 25% of total energy supply for the world's sixth largest economy. For both policymakers and the general public, a "positive climate change" presentation does not generally suffice on its own. Clear visual display of climate science information is essential. We have found the Science On a Sphere (SOS) National Oceanic and Atmospheric Administration science education tool, to be exceptional in this regard. Further, broad dissemination is possible given the SOS network consists of over 120 sites in 23 countries. The new SOS Explorer system, an advanced science education tool, can readily utilize the over 500 available SOS data sets. We have recently developed an arctic amplification and mid-latitude climate change impacts program for the upcoming US National Academy of Sciences' Arctic Matters Symposium/Open House. This SOS and SOS Explorer education program will be described with emphasis on the climate solutions incorporated into this module targeted at US policymakers and invited open house public.

    Full Text Available This paper aims to analyze the possible effects of the housing program “Mi Casa, Mi Vida” in socioeconomic residential segregation in the city of Córdoba (Argentina. These effects are estimated from the study of the socioeconomic residential composition (before and after the implementation of the program, the mapping of residential movements generated by the program and the application of bivariate autocorrelation techniques. Among the key findings, most of the program beneficiaries are concentrated in poor areas surrounded by others in similar conditions. This fact favors the existence of a large cluster of poverty in the peripheries of the city and promotes marginalization and social exclusion.

    2007-01-01

    Based on the data from 36 major cities in 2004 and 2005, this paper analyses the rationality of present housing price level, focusing on the high price-to-income ratio in the market. The results indicate that, current property prices in most cities are reasonable, and the problem occurs only in a few cities. Housing difficulties for urban dwellers are mainly twofold: low affordability of down payment by first-time homebuyers, and low affordability by low-income and medium low-income households. In order to achieve social harmony in the housing sector and provide a healthy environment for the housing market, the government should improve the public housing system and increase input to make public housing affordable.

    In this study, first, HCl emission during the pyrolysis of demolition wood containing polyvinyl chloride (PVC) film and refuse-derived fuel (RDF) converted from municipal wastes was measured with a laboratory scale cylindrical batch reactor. The difference in the HCl emission behavior between both feedstocks was discussed. In the case of the demolition wood with PVC, the effects of wood composition on HCl emission were investigated by not only measuring the HCl emission during the co-pyrolysis of the primary constituents of wood (cellulose, hemi-cellulose and lignin) with PVC film but also by conducting thermogravimetric analysis of the constituents. Finally, the reduction of HCl emission due to blending demolition wood and PVC film with a K-rich biomass was experimentally evaluated as a method for reducing the HCl emission. (authors)

    Recently, entanglement plays an important role in quantum information science. Here we propose an efficient and applicable method which transforms arbitrary three-qubit unknown state to a maximally entangled Greenberger-Horne-Zeilinger state, and the proposed method could be further generalized to multi-qubit case. The proposed setup exploits only linear optical elements and quantum non-demolition detectors using cross-Kerr media. As the quantum non-demolition detection could reveal us the output state of the photons without destroying them. This property may make our proposed setup flexible and can be widely used in current quantum information science and technology.

      通过对财富标志形成理论及房价在货币政策传导机制中所起的作用进行剖析,揭示了房地产成为社会性财富标志的必然性和由于未能进化成法定财富标志而容易泛化的缺陷性.2008年至今,美国推出了三轮量化宽松货币政策(QE),是为求解上述问题而进行的有益尝试,这与林左鸣和闫妍提出以公租房作为法定财富标志的主张不谋而合.鉴于我国中央银行以外汇为主的资产结构导致的货币政策被动、以及房地产市场乱象丛生的现实,必须尽快落实以公租房作为法定财富标志的制度安排.央行对兼具法定和社会性双重财富标志属性的公租房产权进行公开市场操作,投放或回笼基础货币:(1)可以拓宽投资渠道,减少商品房的投资需求,抑制其价格过快上涨;(2)可以优化央行的资产结构,降低外汇占比,提高货币政策的自主性和灵活性;(3)可以引导社会资金投资公租房,解决其融资、建设位置和质量等问题,有利于通过租赁形式实现居者有其所的社会目标.%  After the literature review of the wealth identification theory and the status of the housing prices in the monetary policy transmission mechanism, this article reveals the necessity of real estate being social wealth identification, and discusses that real estate will be generalized if it could not evolve into the fiat wealth identification. Since 2008 to now, the US Federal Reserve has announced three versions of quanti-tative easing monetary policies (QE), trying hard to solve the above problems, which are consistent with proposal suggested by Lin andYan (2012) that public rental houses can be considered to be one type of fiat wealth identifications. In China, monetary policy is passive for foreign exchange is the main asset held by the central bank, and there are many problems unsolved in the real estate market, so we must make institu

    Corinaldesi, Valeria; Moriconi, Giacomo

    2010-04-01

    In this project concrete mixtures were prepared that were characterized by low ductility due to desiccation by using debris from building demolition, which after a suitable treatment was used as aggregate for partial replacement of natural aggregates. The recycled aggregate used came from a recycling plant, in which rubble from building demolition was selected, crushed, cleaned, sieved, and graded. Such aggregates are known to be more porous as indicated by the Saturated Surface Dry (SSD) moisture content. The recycled concrete used as aggregates were added to the concrete mixture in order to study their influence on the fresh and hardened concrete properties. They were added either after water pre-soaking or in dry condition, in order to evaluate the influence of moisture in aggregates on the performance of concrete containing recycled aggregate. In particular, the effect of internal curing, due to the use of such aggregates, was studied. Concrete behavior due to desiccation under dehydration was studied by means of both drying shrinkage test and German angle test, through which shrinkage under the restrained condition of early age concrete can be evaluated.

  10. Stripping in hot mix asphalt produced by aggregates from construction and demolition waste.

    Pérez, I; Pasandín, A R; Gallego, J

    2012-01-01

    This paper analyses the effect of water on the durability of hot asphalt mixtures made with recycled aggregates from construction and demolition debris. Indirect tensile stress tests were carried out to evaluate stripping behaviour. The mixtures tested were fabricated with 0, 20, 40 and 60% recycled aggregates. Two types of natural aggregates were used: schist and calcite dolomite. An increase in the percentage of recycled aggregates was found to produce a decrease in the tensile stress ratio of the hot asphalt mixtures. To study this phenomenon, two and three factor analyses of variance (ANOVA) were performed with indirect tensile stress being used as the dependent variable. The factors studied were the percentage of recycled aggregates (0, 20, 40 and 60%), the moisture state (dry, wet) and the type of natural aggregate (schist, calcite). On the basis of the ANOVA results, it was found that the most important factor affecting resistance was the moisture state (dry, wet) of the specimens. The percentage of recycled aggregate also affected indirect tensile stress, especially in the dry state. The type of natural aggregate did not have a significant effect on indirect tensile stress. The hot asphalt mixture specimens made with different percentages of recycled aggregates from construction and demolition debris and of natural quarry aggregates showed poor stripping behaviour. This stripping behaviour can be related to both the poor adhesion of the recycled aggregates and the high absorption of the mortar of cement adhered to them.

    In an attempt to look at means for reduction of corrosion in boilers, combustion experiments are performed on demolition wood with kaolin as additive. The experiments were performed in a multi-fuel reactor with continuous feed of pellets and by applying staged air combustion. A total characterization of the elemental composition of the fuel, the bottom ash and some particle size stages of fly ash was performed. This was done in order to follow the fate of some of the problematic compounds in demolition wood as a function of kaolin addition and other combustion-related parameters. In particular chlorine and potassium distribution between the gas phase, the bottom ash and the fly ash is reported as a function of increased kaolin addition, reactor temperature and air staging. Kaolin addition of 5 and 10% were found to give the least aerosol load in the fly ash. In addition, the chlorine concentration in aerosol particles was at its lowest levels for the same addition of kaolin, although the difference between 5 and 10% addition was minimal. The reactor temperature was found to have a minimal effect on both the fly ash and bottom ash properties.

    2014-07-15

    Thirty-three samples of construction and demolition waste collected at 11 recycling facilities in Denmark were characterised in terms of total content and leaching of inorganic elements and presence of the persistent organic pollutants PCBs and PAHs. Samples included (i) "clean" (i.e. unmixed) concrete waste, (ii) mixed masonry and concrete, (iii) asphalt and (iv) freshly cast concrete cores; both old and newly generated construction and demolition waste was included. PCBs and PAHs were detected in all samples, generally in non-critical concentrations. Overall, PAHs were comparable to background levels in urban environments. "Old" and "new" concrete samples indicated different PCB congener profiles and the presence of PCB even in new concrete suggested that background levels in raw materials may be an issue. Significant variability in total content of trace elements, even more pronounced for leaching, was observed indicating that the number of analysed samples may be critical in relation to decisions regarding management and utilisation of the materials. Higher leaching of chromium, sulphate and chloride were observed for masonry-containing and partly carbonated samples, indicating that source segregation and management practices may be important. Generally, leaching was in compliance with available leaching limits, except for selenium, and in some cases chromium, sulphate and antimony. Copyright © 2014 Elsevier B.V. All rights reserved.

    A major product recovered from the processing and recycling of construction and demolition (C&D) debris is screened soil, also referred to as fines. A proposed reuse option for C&D debris fines is fill material, typically in construction projects as a substitute for natural soil. Waste material that is reused in a manner similar to soil must first be characterized to examine potential risks to human health and the environment. In Florida, samples of C&D debris fines from 13 C&D debris recycling facilities were characterized for 11 total and leachable heavy metal concentrations. Total metal concentration results (mg/kg) were compared to existing data on background Florida soil concentrations and to Florida's risk-based soil cleanup target levels (SCTLs). All of the detected metals were found to be elevated with respect to background. The 95% upper confidence level of arsenic from 99 samples was 3.2 mg/kg; arsenic presented the greatest limitation to reuse when compared to the SCTLs. Lead was not found to pose a major problem, likely because of the relatively new building infrastructure in Florida, which results in less demolition debris and less material impacted by lead-based paint. The results of batch leaching tests conducted using simulated rainwater (mg/l) were compared directly to risk-based groundwater levels for Florida and were found not to pose a risk using existing risk assessment policies.

    The changes in waste management policy caused by the massive generation of waste materials (e.g. construction and demolition waste material, municipal waste incineration products) has led to an increase in the reuse and recycling of waste materials. For environmental risk assessment, test procedures are necessary to examine waste materials before they can be reused. In this article, results of column and lysimeter leaching tests having been applied to inorganic compounds in a reference demolition waste material are presented. The results show a good agreement between the leaching behaviour determined with the lysimeter unit and the column units used in the laboratory. In view of less time and system requirements compared to lysimeter systems, laboratory column units can be considered as a practicable instrument to assess the time-dependent release of inorganic compounds under conditions similar to those encountered in a natural environment. The high concentrations of elements in the seepage water at the initial stage of elution are reflected by the laboratory column leaching tests. In particular, authorities or laboratories might benefit and have an easy-to-use, but nevertheless reliable, method to serve as a basis for decision-making.

    Recycling plants that size, sort and wash construction and demolition waste can produce high quality aggregate. However, they also produce up to 80ton per hour of filter cake waste containing fine (geopolymers containing silt, which would allow this problematic waste to be beneficially reused as aggregate. This would significantly improve the economic viability of recycling plants that wash wastes. Silt filter cakes have been collected from a number of aggregate washing plants operating in the UK. These were found to contain similar aluminosilicate crystalline phases. Geopolymer samples were produced using silt and silt mixed with either metakaolin or pulverised fuel ash (PFA). Silt geopolymers cured at room temperature had average 7-day compressive strengths of 18.7MPa, while partial substitution of silt by metakaolin or PFA increased average compressive strengths to 30.5 and 21.9MPa, respectively. Curing specimens for 24h at 105 degrees C resulted in a compressive strength of 39.7MPa and microstructural analysis confirmed the formation of dense materials. These strengths are in excess of those required for materials to be used as aggregate, particularly in unbound applications. The implications of this research for the management of waste silt at construction and demolition waste washing plants are discussed.

  17. In-house or outsourced public services? A social and economic analysis of the impact of spending policy on the private wage share in OECD countries

    2017-01-01

    This article analyses the relationship between government spending and the distribution of private income between capital and labour. While most previous research assumes that government spending redistributes in favour of the less wealthy, I distinguish between types of expenditures that enhance the bargaining position of labour – that is, unemployment benefits, public sector employment and investment in new capital – and labour-saving and pro-business types of expenditures – that is, outsourcing to private firms. The results are derived from various panel regression techniques on a panel of 19 Organisation for Economic Co-operation and Development (OECD) countries in the period 1985–2010 and show that expenditures on public sector employment and, to a lesser extent, on new capital prevented the private wage share from declining further, even after controlling for labour market institutions, globalisation and technological change. Conversely, expenditures on outsourcing substantially contributed to reducing the private wage share. Unemployment benefits had a non-significant and negative effect on the private wage share because their increase was the consequence of higher levels of unemployment rather than policy. Implications for theory and policy are drawn, including the support for a public employment-led spending policy. PMID:28919641

    Abstract Insecticide resistance in German cockroaches (Blattella germanica (L.)) has been a barrier to effective control since its first documentation in the 1950s. A necessary first step toward managing resistance is to understand insecticide susceptibility profiles in field-collected strains so that active ingredients (AIs) with lowest resistance levels can be identified. As a first step in this study, diagnostic concentrations (DCs) were determined for 14 insecticide AIs based on lethal concentrations that killed 99% or 90% of the individuals from a susceptible lab strain (JWax-S). Next, cockroaches were collected from two low-income multifamily housing complexes in Danville, IL, and Indianapolis, IN, and used to establish laboratory strains. These strains were screened against the 14 AI-DCs in vial bioassays, and susceptibility profiles were determined by comparing percent mortalities between the field strains relative to the JWax-S strain. Results revealed lowest resistance of field strains to boric acid, abamectin, dinotefuran, clothianidin, thiamethoxam, and chlorfenapyr. For the AIs hydramethylnon and imidacloprid, field strains did not display survivorship different than the lab strain, but >90% mortality was never achieved. Lastly, both field strains displayed resistance to indoxacarb, fipronil, acetamiprid, beta-cyfluthrin, bifenthrin, and lambda-cyhalothrin, but at varying levels. These results satisfy two objectives. First, baseline monitoring DCs were established for 14 insecticides presently registered for use against cockroaches, which represents a useful resource. Second, our findings reveal insecticide AIs with lowest resistance levels for use in forthcoming field studies that will investigate impacts of different insecticide deployment strategies on resistance management and evolution in cockroach field populations.

    2009-08-15

    The past couple of years have seen the continuous further development of cutting techniques employed in demolishing nuclear facilities. This trend is continuing. After mostly mechanical cutting techniques had been used initially, there has been a tendency in the past few years to make increasing use of thermal cutting. Reasons for this preference are the reduced space requirement and the advantages this technique offers in remote handling because of the low weight and the small dimensions of the cutting heads, and the high flexibility in materials to be cut. This results in greater planning reliability in calculating quotations and performing the demolition work. The emissions generated by these techniques are manageable reliably at low additional expense for the required extraction and filter systems. Thermal cutting is likely to achieve wide use in dismantling and demolition of nuclear plant components also in the future. Advanced developments in computer hardware and software allow more and more detailed planning of demolition work. While, in the past, CAD had been applied only to generate two-dimensional drawings, current 3D applications allow animated representations of entire demolition scenes with high accuracy in detail. In this way, potential problems associated with handling large components or using manipulators for cutting can be detected and solved much more easily in the preparatory phase. Although current CAD use can be no substitute for mockup tests, it does help to enhance clearly reliability in planning prior to running mockup tests. (orig.)

    This paper confirms both technical feasibility and economic potential via the use of redundant brick kilns as an alternative option for disposal of the combustible fractions of construction and demolition wastes by a three-stage analysis. To assess such an idea, one brick kiln was selected for performing an engineering feasibility study. First of all, field sampling and lab-analyses were carried out to gain a deeper understanding of the physical, chemical, and thermodynamic properties of the combustible fractions of construction and demolition wastes. Kinetic parameters for the oxidation of the combustible fractions of construction and demolition wastes were therefore numerically calculated from the weight loss data obtained through a practice of thermogravimetric analyzer (TGA). Secondly, an engineering assessment for retrofitting the redundant brick kiln was performed based on integrating several new and existing unit operations, consisting of waste storage, shredding, feeding, combustion, flue gas cleaning, and ash removal. Such changes were subject to the operational condition in accordance with the estimated mass and energy balances. Finally, addressing the economic value of energy recovery motivated a renewed interest to convert the combustible fractions of construction and demolition wastes into useful hot water for secondary uses.

    Quantum error correction is required for a practical quantum computer because of the fragile nature of quantum information. In quantum error correction, information is redundantly stored in a large quantum state space and one or more observables must be monitored to reveal the occurrence of an error, without disturbing the information encoded in an unknown quantum state. Such observables, typically multi-quantum-bit parities, must correspond to a special symmetry property inherent in the encoding scheme. Measurements of these observables, or error syndromes, must also be performed in a quantum non-demolition way (projecting without further perturbing the state) and more quickly than errors occur. Previously, quantum non-demolition measurements of quantum jumps between states of well-defined energy have been performed in systems such as trapped ions, electrons, cavity quantum electrodynamics, nitrogen-vacancy centres and superconducting quantum bits. So far, however, no fast and repeated monitoring of an error syndrome has been achieved. Here we track the quantum jumps of a possible error syndrome, namely the photon number parity of a microwave cavity, by mapping this property onto an ancilla quantum bit, whose only role is to facilitate quantum state manipulation and measurement. This quantity is just the error syndrome required in a recently proposed scheme for a hardware-efficient protected quantum memory using Schrödinger cat states (quantum superpositions of different coherent states of light) in a harmonic oscillator. We demonstrate the projective nature of this measurement onto a region of state space with well-defined parity by observing the collapse of a coherent state onto even or odd cat states. The measurement is fast compared with the cavity lifetime, has a high single-shot fidelity and has a 99.8 per cent probability per single measurement of leaving the parity unchanged. In combination with the deterministic encoding of quantum information in cat

    The U.S. Department of Veterans Affairs (VA) is transitioning to a Housing First approach to placement of veterans in permanent supportive housing through the use of rental vouchers, an ambitious organizational transformation. This qualitative study examined the experiences of eight VA facilities undertaking this endeavor in 2012. A multidisciplinary team interviewed facility leadership, midlevel managers, and frontline staff (N=95 individuals) at eight VA facilities representing four U.S. regions. The team used a semistructured interview protocol and the constant comparative method to explore how individuals throughout the organizations experienced and responded to the challenges of transitioning to a Housing First approach. Frontline staff faced challenges in rapidly housing homeless veterans because of difficult rental markets, the need to coordinate with local public housing authorities, and a lack of available funds for move-in costs. Staff sought to balance their time spent on housing activities with intensive case management of highly vulnerable veterans. Finding low-demand sheltering options (that is, no expectations regarding sobriety or treatment participation, as in the Housing First model) for veterans waiting for housing presented a significant challenge to implementation of Housing First. Facility leadership supported Housing First implementation through resource allocation, performance monitoring, and reliance on midlevel managers to understand and meet the challenges of implementation. The findings highlight the considerable practical challenges and innovative solutions arising from a large-scale effort to implement Housing First, with particular attention to the experiences of individuals at all levels within an organization.

    2009-05-01

    The nitrogen-vacancy color center (NVC) in diamond, which possesses a long-lived electronic spin (S=1) ground state with optical addressability, is a promising platform for quantum networks, single-photon sources, and nanoscale magnetometers. Here, we make use of a nuclear spin based quantum memory to demonstrate quantum non-demolition measurement of a solid-state spin qubit. By entangling the electron spin with a polarized carbon-13 spin (I=1/2) in the lattice, we have repeated optical measurement of the electron spin for the polarization lifetime of the nuclear spin. We show relative improvements in signal-to-noise of greater than 300%. These techniques can be used to improve the sensitivity of NVC magnetometers.

    This paper intends to analyze the microstructure of concrete with recycled aggregates (RA) from construction and demolition waste from various Portuguese recycling plants. To that effect, several scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) analyses were performed. Various concrete mixes were evaluated in order to analyze the influence of the RA's collection point and consequently of their composition on the mixes' characteristics. Afterward all the mixes were subjected to the capillary water absorption test in order to quantitatively evaluate their porosity. Results from the SEM/EDS analysis were compared with those from capillary water absorption test. The SEM/EDS analysis showed that the bond capacity of aggregates to the new cement paste is greatly influenced by the RA's nature. On the other hand, there was an increase in porosity with the incorporation of RA.

    2009-05-01

    The fundamental sensitivity of an atomic magnetometer is limited by spin projection noise. In the case of uniform spin relaxation, it is well understood that it is not possible to improve the sensitivity using spin squeezing induced by quantum non-demolition (QND) measurement for measurement time scales longer than spin relaxation time [1, 2]. It is however possible to increase the bandwidth of the magnetometer using QND measurement. Here we experimentally demonstrate, in excellent agreement with the theory, an improvement in the bandwidth of our scalar alkali vapor atomic magnetometer using continuous QND measurement. We also investigate the possibility of improving sensitivity of our magnetometer in the special case in which the spin relaxation is time dependent. The case of time dependent spin relaxation naturally arises in high polarization regime in an alkali-alkali spin-exchange relaxation dominated atomic sample. [1] S. F. Huelga, Phys. Rev.

    Demolition Waste, Construction Waste and Excavation Waste will in a modern society represent a major part of the total amount of the industrial wastes. Implementation of the Regulation for Industrial Waste in Copenhagen has resulted insignificant changes in the transportation and processing of this type of waste was typically disposed of as mixed waste on landfill sites and open dumps. Today most of this waste is sorted at the source (see figure 1) and recycled namely as secondary raw materials. This change in the disposal of construction waste etc, is due to two main factors: implementation of the regulation of commercial wastes and a significant raise in the (governmental) waste tax on specially landfilling activities.

    The Sagnac speed meter interferometer topology can potentially provide enhanced sensitivity to gravitational waves in the audio-band compared to equivalent Michelson interferometers. A challenge with the Sagnac speed meter interferometer arises from the intrinsic lack of sensitivity at low frequencies where the velocity-proportional signal is smaller than the noise associated with the sensing of the signal. Using as an example the on-going proof-of-concept Sagnac speed meter experiment in Glasgow, we quantify the problem and present a solution involving the extraction of a small displacement-proportional signal. This displacement signal can be combined with the existing velocity signal to enhance low frequency sensitivity, and we derive optimal filters to accomplish this for different signal strengths. We show that the extraction of the displacement signal for low frequency control purposes can be performed without reducing significantly the quantum non-demolition character of this type of interferometer.

    Full Text Available This special issue on housing and socio-spatial inclusion had its genesis in the 5th Housing Theory Symposium (HTS on the theme of housing and space, held in Brisbane, Australia in 2013. In late 2013 we put out a call for papers in an attempt to collect an initial suite of theoretical and empirical scholarship on this theme. This collection of articles progresses our initial discussions about the theoretical implications of adding the “social” to the conceptual project of thinking through housing and space. We hope that this special issue will act as a springboard for a critical review of housing theory, which could locate housing at the centre of a much broader network of social and cultural practices across different temporal trajectories and spatial scales. This editorial presents an overview of the theoretical discussions at the HTS and summarises the six articles in this themed issue, which are: (1 The meaning of home in home birth experiences; (2 Reconceptualizing the “publicness” of public housing; (3 The provision of visitable housing in Australia; (4 The self-production of dwellings made by the Brazilian new middle class; (5 Innovative housing models and the struggle against social exclusion in cities; and (6 A theoretical and an empirical analysis of “poverty suburbanization”.

    Currently, under the background of the aggravating of China ’ s local governmental debt, there is problem in debt payback sources because financial expenditure for public low rent housing construction is big and 82 because governmental debt is huge. Although it can temporarily solve the problem for Chongqing to hope to ensure debt payback sources by selling public low rent housing, it is not helpful to the sustainability of public low rent housing supply. The bottleneck of the sustainable development for the construction and management of Chongqing public low rent housing emanates from governmental independently holding huge financial pressure and potential debt risk pressure. In order to realize long-run sustainable development of Chongqing public low rent housing supply, Chongqing municipal government should need to adjust its role position and to effectively integrate social resources in public low rent housing construction, change the mode for municipal government to be only investment main body for public low rent housing, attract social agencies to participate in the housing construction, increase the capital source channels for the housing construction, reduce the capital investment in newly-building public low rent housing, and consolidate its management in order to realize the maximization of the housing exploitation.%目前,在我国地方债务风险加剧的背景下,公租房建设财政支出大、政府举债多,使其还款来源存在问题。重庆寄希望于通过出售公租房来保证还款来源的做法虽然能够解一时之急,但并不利于公租房供应的可持续性。重庆公租房建设与运营可持续发展的瓶颈在于政府独自承担巨大的财政压力和债务风险潜在压力。为了实现重庆公租房供应的长期可持续发展,政府需要调整其在公租房建设中的角色定位和有效整合社会资源,应改变政府为公租房唯一投资主体的模式,吸引社会机构参与

    Full Text Available SUMMARY This paper addresses the issue of the urban obsolescence of public space of social housing neighbourhoods built during the post-war period in Great Britain. Great Britain has been chosen because of the active role played by modern architects in the construction of the welfare state advocated by post-war governments, which involved building large areas of social housing. The aims of this paper are to understand the context in which these neighbourhoods were built as well as their evolution and the complexity of their obsolescence. To achieve these objectives, it first looks at the causes that prompted the slum clearance process, at its implementation during the post-war reconstruction and at the effects that this process has had on contemporary cities. Secondly, it is illustrated through a detailed analysis of a case study, Loughborough Estate in Brixton, London, looking at the initial conditions of the council estate when it was built, investigating its evolution over the past five decades and factors that may have contributed to the obsolescence of its public space and to its social problems. The paper concludes with a warning that a generalist critique of modern architecture does not solve the problems of such neighbourhoods, but a substantial intervention on the public space is needed to bring them to life. These interventions should focus on the spatial configuration of public space and its design and maintenance.RESUMEN Este artículo aborda la cuestión de la obsolescencia urbana del espacio público en las barriadas de viviendas sociales construidas durante el periodo de post-guerra en Gran Bretaña.

    Full Text Available In the face of increasing and differentiating the low-cost housing demand and the trend of establishing new paradigms in the contemporary housing design, the architectural investigation has replaced into its disciplinary statement the topic of housing as central question in research and design experimentation. The city of Barcelona has codified in the last years innovative modalities of public management in social housing, offering interesting points of reflection on the idea of housing and of Mediterranean quality in urban, architectural and constructive terms. The paper proposes a key to the reading on the recent experiences of social housing in Barcelona illustrating the different forms through which architecture interprets the relationship between housing and public space, between innovation and constructive tradition.

    The proposed new demolition landfill at Test Area North on the Idaho National Engineering and Environmental Laboratory (INEEL) will support ongoing demolition and decontamination within the facilities on the north end of the INEEL. In June of 2003, the INEEL Cultural Resource Management Office conducted archival searches, field surveys, and coordination with the Shoshone-Bannock Tribes to identify all cultural resources that might be adversely affected by the project and to provide recommendations to protect those listed or eligible for listing on the National Register of Historic Places. These investigations showed that landfill construction and operation would affect two significant cultural resources. This report outlines protective measures to ensure that these effects are not adverse.

    2011-01-01

    Full Text Available Two themes are evident in housing research in Ghana. One involves the study of how to increase the number of dwellings to correct the overall housing deficit, and the other focuses on how to improve housing for slum dwellers. Between these two extremes, there is relatively little research on why the existing buildings are poorly maintained. This paper is based on a review of existing studies on inadequate housing. It synthesises the evidence on the possible reasons for this neglect, makes a case for better maintenance and analyses possible ways of reversing the problem of inadequate housing.

  3. The Winners in China’s Urban Housing Reform

    Science.gov (United States)

    Logan, John R.; Fang, Yiping; Zhang, Zhanxin

    2013-01-01

    Housing reform in China has proceeded on two tracks: privatization of public housing and development of a new private housing sector. During this period of transition, rents have remained relatively low in the remaining public housing, and purchase prices offered to occupants of public housing have been well below market prices. Although these rents and prices are partly based on known formulas, there is considerable variability in how much people pay for similar apartments. This study uses 2000 Census data to estimate the housing subsidy received by the remaining renters in the public sector and purchasers of public housing, based on private sector prices for housing of comparable quality and size. The paper also analyzes variation in the estimated discount from market prices that these people receive. The findings show that the biggest winners in China’s transition from socialist housing allocation are those who were favored in the previous system, based on such factors as residence status, education and occupation.

    2013-01-01

    In order to obtain lucidity, it is essential to choose adequate terminology when speaking of prehistoric houses. The understanding of house construction requires a terminology with a focus on construction. Very often, archaeologists instead use a terminology with a focus on the remains, and use an inadequate terminology for constructions, indicating that they do not fully consider how the constructions work. The article presents some suggestions for adequate construction terminology.

It is clear that type flood events may cause social problems and losses is difficult financing from public resources, especially in the context of the existence of budget constraints. The only viable system to cope with such disasters is insurance system that has the ability to spread risks by reinsurance Natural disasters - earthquakes, floods, landslides - are just some of the risks that may threaten your home. And if natural disasters can seem distant danger, think as fires, floods caused by broken pipes or theft of household goods are trouble can happen anytime to anyone. To protect yourself in such unpleasant situations, whose frequency is unfortunately on the rise, it is necessary to be assured. Thus, you will be able to recover losses in the event that they occur. The house is undoubtedly one of the most important assets we own. Therefore, the Romans began to pay increasingly more attention to domestic insurance products. Since 2011, voluntary home insurance, life insurance with, were the most dynamic segments of the market.

    Yuan, Fang; Shen, Li-yin; Li, Qi-ming

    2011-12-01

    Construction and demolition (C&D) waste is becoming a major contributor to environmental pollution. In Shanghai, China, the quantity of C&D waste is 2.11E+07 t/yr, which accounts for 45% of the total quantity of solid waste. There has been a growing promotion of recycling C&D waste as an effective way to solve this waste problem. However, the evaluation of the efficiency of recycling C&D waste as a potential source of resources is largely based on traditional economic analysis. The economic analysis emphasizes money instead of the harmony between economic benefit and environmental effects. There is a need for a new strategic approach to investigate the efficiency of recycling C&D waste to achieve the integration between economic, social and environmental effects. Emergy theory can be employed to analyze different recycling options for C&D waste. With reference to the Chinese construction industry, this paper demonstrates that the close-loop recycling option is better than the open-loop recycling option for C&D waste in terms of the integration of social, environmental and sustainable aspects. To evaluate different technology solutions for C&D waste recycling, the emergy theory and method is not limited to a cost-benefit balance but can include economic, social, environmental and sustainable effects.

    The construction and demolition waste generation rates (C&D WGRs) is an important factor in decision-making and management of material waste in any construction site. The present study investigated WGRs by conducting on-site waste sorting and weighing in four ongoing construction projects in Shenzhen city of South China. The results revealed that WGRs ranged from 3.275 to 8.791 kg/m(2) and miscellaneous waste, timber for formwork and falsework, and concrete were the three largest components amongst the generated waste. Based on the WGRs derived from the research, the paper also discussed the main causes of waste in the construction industry and attempted to connect waste generation with specific construction practices. It was recommended that measures mainly including performing waste sorting at source, employing skilful workers, uploading and storing materials properly, promoting waste management capacity, replacing current timber formwork with metal formwork and launching an incentive reward program to encourage waste reduction could be potential solutions to reducing current WGRs in Shenzhen. Although these results were derived from a relatively small sample and so cannot justifiably be generalized, they do however add to the body of knowledge that is currently available for understanding the status of the art of C&D waste management in China.

    2012-01-01

    Full Text Available A systematic approach was developed to review, revise and adapt existing exposure control guidance used in developed countries for use in developing countries. One-page employee and multiple-page supervisor guidance sheets were adapted from existing documents using a logic framework and workers were trained to use the information to improve work practices. Interactive, hands-on training was delivered to 26 workers at five small-scale demolition projects in Maputo City, Mozambique, and evaluated. A pre-and-post walkthrough survey used by trained observers documented work practice changes. Worker feedback indicated that the training was effective and useful. Workers acquired knowledge (84% increase, p < 0.01 and applied the work practice guidance. The difference of proportions between use of work practice components before and after the intervention was statistically significant (p < 0.05. Changes in work practices following training included preplanning, use of wet methods and natural ventilation and end-of-task review. Respirable dust measurements indicated a reduction in exposure following training. Consistency in observer ratings and observations support the reliability and validity of the instruments. This approach demonstrated the short-term benefit of training in changing work practices; follow-up is required to determine the long-term impact on changes in work practices, and to evaluate the need for refresher training.

  15. Recycling waste brick from construction and demolition of buildings as pozzolanic materials.

    This investigation elucidates the pozzolic characteristics of pastes that contain waste brick from building construction and demolition wastes. The TCLP leaching concentrations of waste brick for the target cations or heavy metals were all lower than the current regulatory thresholds of the Taiwan EPA. Waste brick had a pozzolanic strength activity index of 107% after 28 days. It can be regarded as a strong pozzolanic material. The compressive strengths of waste brick blended cement (WBBC) that contain 10% waste brick increased from 71.2 MPa at 28 days to 75.1 MPa at 60 days, an increase of approximately 5% over that period. At 28 days, the pozzolanic reaction began, reducing the amount of Ca(OH)(2) and increasing the densification. The intensity of the peak at 3640 cm(- 1) associated with Ca(OH)(2) is approximately the same for ordinary Portland cement (OPC) pastes. The hydration products of all the samples yield characteristics peaks at 978 cm(-1) associated with C-S-H, and at ~3011 cm(-1) and 1640 cm(-1) associated with water. The samples yield peaks at 1112 cm(-1), revealing the formation of ettringite. In WBBC pastes, the ratio Q(2)/Q(1) increases with curing time. These results demonstrate that increasing the curing time increases the number of linear polysilicate anions in C-S-H. Experimental results reveal that waste brick has potential as a pozzolanic material in the partial replacement of cement.

  16. USE OF CONSTRUCTION AND DEMOLITION WASTES AS RAW MATERIALS IN CEMENT CLINKER PRODUCTION

    2006-01-01

    The aim of the present paper was to investigate the possibility of utilizing Construction and Demolition(C&D) wastes as substitutes of Portland cement raw meal. The C&D wastes that were so used, were the Recycled Concrete Aggregates (RCA) and the Recycled Masonry Aggregates (RMA) derived from demolished buildings in Attica region, Greece. RCA and RMA samples were selected because of their calcareous and siliceous origin respectively,which conformed the composition of the ordinary Portland cement raw meal. For that reason, six samples of cement raw meals were prepared: one with ordinary raw materials, as a reference sample, and five by mixing the reference sample with RCA and RMA in appropriate proportions. The effect on the reactivity of the generated mixtures, was evaluated on the basis of the free lime content (fCaO) in the mixtures sintered at 1350℃, 1400℃ and 1450℃. Test showed that the added recycled aggregates improved the burnability of the cement raw meal without affecting negatively the cement clinker properties. Moreover, the formation of the major components (C3S, C2S, C3A and C4AF) of the produced clinkers(sintered at 1450℃) was corroborated by X-Ray Diffraction (XRD).

    The abundant generation of construction and demolition (C&D) waste presents a significant challenge to the sustainable development of the construction industry in Mainland China. As the implementer of construction activities, the contractor's C&D waste management performance plays an important role in C&D waste minimization. This paper aims to investigate the determinants of the contractor's C&D waste management behavior in Mainland China. The Theory of Planned Behavior (TPB) was selected as the basis of the theoretical model. In addition, three contextual constructs (i.e., economic viability, governmental supervision, and project constraints) were introduced, formulating the initial model. Based on the initial model, eight constructs were identified and seven hypotheses were proposed. A questionnaire survey was conducted to collect data and a Structural Equation Modeling (SEM) analysis was employed to test the proposed hypotheses. Results showed that the C&D waste management intention is not a significant determinant of contractor's C&D waste management behavior. The most important determinant is economic viability, followed by governmental supervision as the second most important determinant. Nevertheless, the construct of project constraints is an insignificant determinant for contractor's adoption of C&D waste management behavior. The research findings imply that, in Mainland China, the government, at this stage, plays an important role in guiding and promoting the contractor to exhibit better C&D waste management behavior.

    The vast majority of construction material is inert and can be managed as nonhazardous. However, structures may have either been built with some environmentally unfriendly substances such as brominated flame retardants (BFRs), or have absorbed harmful elements such as heavy metals. This study focuses on end-of-life construction materials, i.e. construction and demolition (C&D) waste components. The aim was to characterize the concentration of extremely harmful substances, primarily BFRs, including hexabromocyclododecane (HBCD) and polybrominateddiphenyl ethers (PBDEs). Results revealed extremely high contents of HBCD and PBDEs in typical C&D waste components, particularly polyurethane foam materials. Policies should therefore be developed for the proper management of C&D waste, with priority for POP-containing debris. The first priority is to develop a classification system and procedures to separate out the harmful materials for more extensive processing. Additionally, identification and quantification of the environmental implications associated with dumping-dominated disposal of these wastes are required. Finally, more sustainable materials should be selected for use in the construction industry.

    Construction and demolition waste (C&DW) is currently a worldwide issue, and the situation is the worst in China due to a rapid increase in the construction industry and the short life span of China's buildings. To create an opportunity out of this problem, comprehensive prevention measures and effective management strategies are urgently needed. One major gap in the literature of waste management is a lack of estimations on future C&DW generation. Therefore, this paper presents a forecasting procedure for C&DW in China that can forecast the quantity of each component in such waste. The proposed approach is based on a GM-SVR model that improves the forecasting effectiveness of the gray model (GM), which is achieved by adjusting the residual series by a support vector regression (SVR) method and a transition matrix that aims to estimate the discharge of each component in the C&DW. Through the proposed method, future C&DW volume are listed and analyzed containing their potential components and distribution in different provinces in China. Besides, model testing process provides mathematical evidence to validate the proposed model is an effective way to give future information of C&DW for policy makers.

    Wastes from construction activities constitute nowadays the largest by quantity fraction of solid wastes in urban areas. In addition, it is widely accepted that the particular waste stream contains hazardous materials, such as insulating materials, plastic frames of doors, windows, etc. Their uncontrolled disposal result to long-term pollution costs, resource overuse and wasted energy. Within the framework of the DEWAM project, a web-based Decision Support System (DSS) application - namely DeconRCM - has been developed, aiming towards the identification of the optimal construction and demolition waste (CDW) management strategy that minimises end-of-life costs and maximises the recovery of salvaged building materials. This paper addresses both technical and functional structure of the developed web-based application. The web-based DSS provides an accurate estimation of the generated CDW quantities of twenty-one different waste streams (e.g. concrete, bricks, glass, etc.) for four different types of buildings (residential, office, commercial and industrial). With the use of mathematical programming, the DeconRCM provides also the user with the optimal end-of-life management alternative, taking into consideration both economic and environmental criteria. The DSS's capabilities are illustrated through a real world case study of a typical five floor apartment building in Thessaloniki, Greece.

    On December 20, 2015 at 11:40 am a landslide in one of China's most advanced cities, Shenzhen, killed 73 people and damaged 33 buildings. In the absence of heavy rainfall or earthquakes, the landslide was an unexpected and profound shock to many people. According to China's Ministry of Land and Resources, the landslide was triggered by the collapse of an enormous pile of construction and demolition waste (CDW). With China's rapid urbanization, an increasing amount of CDW is being generated, especially in major cities. In total, China produces some 30% of the world's municipal solid waste and of this about 40% is CDW. To prevent landslides associated with CDW, the volume of waste dumped in landfills should be regulated. More specifically 4-Rs (reduce, reuse, recycle and recover) policies should be implemented more widely and efficiently. Although landfill will continue to be an important disposal option, proper management and careful monitoring of CDW are urgently needed to satisfy pressing safety issues. International collaboration, sharing of knowledge, and use of the latest technologies are needed so that the similar landslides can be prevented in China and elsewhere.

    Column experiments were performed to examine (a) the potential for leachate from construction and demolition (C&D) debris landfills to mobilize naturally-occurring iron and arsenic from soils underlying such facilities and (b) the ability of crushed limestone to remove these aqueous phase pollutants. In duplicate columns, water was added to a 30-cm layer of synthetic C&D debris, with the resulting leachate serially passed through a 30-cm soil layer containing iron and arsenic and a 30-cm crushed limestone layer. This experiment was conducted for two different soil types (one high in iron (10,400mg/kg) and the second high in iron (5400mg/kg) and arsenic (70mg/kg)); also monitored were control columns for both soil types with water infiltration alone. Despite low iron concentrations in the simulated C&D debris leachate, elevated iron concentrations were observed when leachate passed through the soils; reductive dissolution was concluded to be the cause of iron mobilization. In the soil containing elevated arsenic, increased iron mobilization from the soil was accompanied by a similar but delayed arsenic mobilization. Since arsenic sorbs to oxidized iron soil minerals, reductive dissolution of these minerals results in arsenic mobilization. Crushed limestone significantly reduced iron (to values below the detection limit of 0.01mg/L in most cases); however, arsenic was not removed to any significant extent.

    The present work addresses the development of novel construction materials utilising commercial grade nano-silica and recycled aggregates retrieved from construction and demolition waste. For this, experimental work has been carried out to examine the influence of nano-silica and recycled aggregates on compressive strength, modulus of elasticity, water absorption, density and volume of voids of concrete. Fully natural and recycled aggregate concrete mixes are designed by replacing cement with three levels (0.75%, 1.5% and 3%) of nano-silica. The results of the present investigation depict that improvement in early days compressive strength is achieved with the incorporation of nano-silica in addition to the restoration of reduction in compressive strength of recycled aggregate concrete mixes caused owing to the replacement of natural aggregates by recycled aggregates. Moreover, the increase in water absorption and volume of voids with a reduction of bulk density was detected with the incorporation of recycled aggregates in place of natural aggregates. However, enhancement in density and reduction in water absorption and volume of voids of recycled aggregate concrete resulted from the addition of nano-silica. In addition, the results of the study reveal that nano-silica has no significant effect on elastic modulus of concrete.

The methods used are deduction and normative analysis. The results show that under the dual system of residential land supply, the local governments do not have the internal incentive of continuously supplying land for the public rental houses, and meanwhile the normal pattern of real estate business can hardly support the development of public rental housing. Therefore, the adjustment of land institution and the redesign of the related policy are needed so as to reduce the costs of public rental housing with completely legal ownership. It further attracts the social investment, forming the common-interests model of local governments, companies and households. The conclusion is that the current development pattern with local governments' dominating role can be complemented by the market forces through the reform of related land institution, which is crucial for the sustainable development of the public rental housing in China.

    This paper presents the development and evaluation of the train-the-trainer (TTT) workshop for lay resident leaders to be lay health promoters. The TTT workshop aimed to prepare the trainees to implement and/or assist in conducting a series of community-based family well-being activities for the residents in a public low rent housing estate, entitled "Learning Families Project", under the FAMILY project. The four-hour TTT workshop was conducted for 32 trainees (72% women, 43% aged ≥ 60, 41% ≤ elementary school education). The workshop aimed to promote trainees' knowledge, self-efficacy, attitude and practice of incorporating the positive psychology themes into their community activities and engaging the residents to join these activities and learn with their family members. Post-training support was provided. The effectiveness of the TTT was examined by self-administered questionnaires about trainees' reactions to training content, changes in learning and practice at three time points (baseline, and immediately and one year after training), and the difference in residents' survey results before and after participating in the community activities delivered by the trainees. The trainees' learning about the general concepts of family well-being, learning family, leadership skills and planning skills increased significantly with medium to large effect sizes (Cohen's d: 0.5-1.4) immediately after the training. The effects of perceived knowledge and attitude towards practice were sustained to one year (Cohen's d: 0.4-0.6). The application of planning skills to implement community activities was higher at one year (Cohen's d: 0.4), compared with baseline. At one year, the residents' survey results showed significant increases in the practice of positive communication behaviours and better neighbour cohesions after joining the family well-being activities of LFP. Qualitative feedback supported the quantitative results. Our TTT workshop could serve as a practical

    Full Text Available The mix design for asphalt mixtures containing recycled aggregates from construction and demolition debris was evaluated. The tests conducted to characterize the mechanical behaviour of these mixtures showed that the mechanical properties of mixtures with recycled and virgin aggregate are similar. The asphalt mixtures containing recycled aggregate proved to have lower resistance to water action. Nonetheless, recycled aggregate was found to be potentially usable in asphalt mixtures if higher quality materials are selected and such low resistance is corrected. This will call for expanding upon the preliminary work described in the present article.En este trabajo se dosificaron mezclas bituminosas fabricadas con áridos reciclados de residuos de construcción y demolición. Se realizaron una serie de ensayos que permitieron caracterizar el comportamiento mecánico de estas mezclas. Los parámetros mecánicos de las mezclas con áridos reciclados son similares a los de las mezclas fabricadas únicamente con áridos naturales de cantera. Sin embargo, las mezclas bituminosas con áridos reciclados tuvieron un mal comportamiento frente a la disminución de la resistencia por pérdida de cohesión por la acción del agua. No obstante, mediante la selección de materiales de mejor calidad y corrección de este mal comportamiento, existen posibilidades de utilizar áridos reciclados en mezclas bituminosas. Para ello será necesario ampliar la primera aproximación realizada en este artículo.

    Proper disposal of construction and demolition wastes (CDW) has received wide attention recently due to significantly large quantities of waste streams collected from razed or retrofitted buildings in many metropolitan regions. Burning the combustible fractions of CDW (CCDW) and possibly recovering part of the heat content for economic uses could be valuable for energy conservation. This paper explores the oxidation kinetics of CCDW associated with its ash characterization. Kinetic parameters for the oxidation of CCDW were numerically calculated using thermal gravimetric analysis (TGA) and the resultant rate equations were therefore developed for illustrating the oxidation processes of CCDW simultaneously. Based on three designated heating rates, each of the oxidation processes can be featured distinctively with five different stages according to the rate of weight change at the temperature between 300 K and 923 K. In addition, Fourier transform infrared (FTIR) spectroscopy was employed, associated with a lab-scale fixed-bed incinerator for monitoring the composition of flue gas. Carbon dioxide (CO2) was found as a major component in the flue gas. The fuel analysis also included an ash composition analysis via the use of X-ray powder diffraction (XRD), atomic absorption (AA) spectroscopy, inductively coupled plasma-atomic emission spectroscopy (ICP-AES), and scanning electron microscopy-energy dispersive spectroscopy (SEM-EDX). The ash streams were identified as nonhazardous materials based on the toxicity characteristic leaching procedure (TCLP). Overall, the scientific findings gained in this study will be helpful for supporting a sound engineering design of real-world CCDW incineration systems.

    2016-04-01

    This paper provides a review of the literature that applies the life cycle assessment (LCA) methodology to the assessment of the environmental performance of the life cycle of construction and demolition waste (CDW) management systems. This article is focused on generating a general mapping of the literature and on identifying the best practices in compliance with LCA framework and proposing directions for future LCA studies in this field. The temporal evolution of the research in this field and the aim of the studies have grown in parallel with the legal framework related to waste and energy efficiency of buildings. Most studies have been published in Europe, followed by USA. Asia and Australia, being at an incipient application stage to the rest of the world. Topics related to "LCA of buildings, including their EoL" and "LCA of general CDW management strategies" are the most frequently analysed, followed by "LCA of EoL of construction elements" and "LCA of natural material vs recycled material". Regarding the strategies, recycling off-site and incineration, both combined with landfill for the rejected fractions, are the most commonly applied. Re-use or recycling on-site is the strategy least applied. The key aspect when LCA is applied to evaluate CDW management systems is the need to normalise which processes to include in the system boundary and the functional unit, the use of inventory data adapted to the context of the case study and the definition of a common set of appropriate impact assessment categories. Also, it is important to obtain results disaggregated by unit processes. This will allow the comparison between case studies.

  4. Challenges in automatic sorting of construction and demolition waste by hyperspectral imaging

    2016-05-01

    EU-28 countries currently generate 460 Mt/year of construction and demolition waste (C&DW) and the generation rate is expected to reach around 570 Mt/year between 2025 and 2030. There is great potential for recycling C&DW materials since they are massively produced and content valuable resources. But new C&DW is more complex than existing one and there is a need for shifting from traditional recycling approaches to novel recycling solutions. One basic step to achieve this objective is an improvement in (automatic) sorting technology. Hyperspectral Imaging is a promising candidate to support the process. However, the industrial distribution of Hyperspectral Imaging in the C&DW recycling branch is currently insufficiently pronounced due to high investment costs, still insufficient robustness of optical sensor hardware in harsh ambient conditions and, because of the need of sensor fusion, not well-engineered special software methods to perform the (on line) sorting tasks. Thereby frame rates of over 300 Hz are needed for a successful sorting result. Currently the biggest challenges with regard to C&DW detection cover the need of overlapping VIS, NIR and SWIR hyperspectral images in time and space, in particular for selective recognition of contaminated particles. In the study on hand a new approach for hyperspectral imagers is presented by exploiting SWIR hyperspectral information in real time (with 300 Hz). The contribution describes both laboratory results with regard to optical detection of the most important C&DW material composites as well as a development path for an industrial implementation in automatic sorting and separation lines. The main focus is placed on the closure of the two recycling circuits "grey to grey" and "red to red" because of their outstanding potential for sustainability in conservation of construction resources.

    Highlights: • Novel biological technique for gypsum removal from CDD. • CDDS leachate treatment performed using different sulfate reducing bioreactors. • Gypsum in CDD can be used as a source of sulfate for sulfate reducing bacteria. • High calcium concentration (1000 mg L{sup −1}) did not affect the bioreactor performance. - Abstract: Due to the contamination of construction and demolition debris (CDD) by gypsum drywall, especially, its sand fraction (CDD sand, CDDS), the sulfate content in CDDS exceeds the posed limit of the maximum amount of sulfate present in building sand (1.73 g sulfate per kg of sand for the Netherlands). Therefore, the CDDS cannot be reused for construction. The CDDS has to be washed in order to remove most of the impurities and to obtain the right sulfate content, thus generating a leachate, containing high sulfate and calcium concentrations. This study aimed at developing a biological sulfate reduction system for CDDS leachate treatment and compared three different reactor configurations for the sulfate reduction step: the upflow anaerobic sludge blanket (UASB) reactor, inverse fluidized bed (IFB) reactor and gas lift anaerobic membrane bioreactor (GL-AnMBR). This investigation demonstrated that all three systems can be applied for the treatment of CDDS leachate. The highest sulfate removal efficiency of 75–85% was achieved at a hydraulic retention time (HRT) of 15.5 h. A high calcium concentration up to 1000 mg L{sup −1} did not give any adverse effect on the sulfate removal efficiency of the IFB and GL-AnMBR systems.

    城市的公共投入对城市的空间结构有着极大的影响,这将导致消费者对于商品住宅偏好的改变,从而进一步影响商品住宅价格趋势的变化。本文从城市公共基础投入这一角度,采用了对区域居民生活便利性影响的重要投入指标,如城镇固定资产投资、教育支出、城市居民医疗卫生支出为指标,运用面板数据模型检验城市公共基础投入与商品住宅价格之间的关系。以西安各区域为例进行的实证研究结果表明:城市公共基础投入与商品住宅价格之间存在着正相关的关系,并且郊区的公共基础投入对商品住宅价格的影响比市区要显著,由此得出政府在郊区基础设施等的重点投入会使得消费者对于商品住宅选择的区位偏好发生了改变,从而会影响西安郊区商品住宅价格的变化。%The public investment of a city has a great inlfuence on urban spatial structure, it will lead to a change of consumers’ commodity preferences on residential house, thus it will have a further inlfuence on the commodity residential house price. Based on this , the paper uses some important indexes to relfect the convenience inlfuence level of regional residents’ life, such as capital investment, educational expenditure and medical care, and the paper uses the panel data model to examine the relationship between the public investment and the commodity house prices. Taking seven areas of Xi’an as an example, the empirical study result shows that:the public investment and the commodity house price has a positive relationship, and the public investment have a more signiifcant inlfuence on the suburbs house price than the urban house price, thus the government on public investment should render consumers to change location preferences of commodity residential house, and it will lead to the suburbs commodity house prices increase.

    We propose an all-optical scheme to perform a non-demolition measurement of a single hole spin localized in a quantum-dot molecule. The latter is embedded in a microcavity and driven by two lasers. This allows to induce Raman transitions which entangle the spin state with the polarization of the emitted photons. We find that the measurement can be completed with high fidelity on a timescale of 100 ps, shorter than the typical T2. Furthermore, we show that the scheme can be used to induce and ...

(FH) is proud to submit the Plutonium Finishing Plant (PFP) 241-Z liquid Waste Treatment Facility Deactivation and Demolition (D&D) Project for consideration by the Project Management Institute as Project of the Year for 2008. The decommissioning of the 241-Z Facility presented numerous challenges, many of which were unique with in the Department of Energy (DOE) Complex. The majority of the project budget and schedule was allocated for cleaning out five below-grade tank vaults. These highly contaminated, confined spaces also presented significant industrial safety hazards that presented some of the most hazardous work environments on the Hanford Site. The 241-Z D&D Project encompassed diverse tasks: cleaning out and stabilizing five below-grade tank vaults (also called cells), manually size-reducing and removing over three tons of process piping from the vaults, permanently isolating service utilities, removing a large contaminated chemical supply tank, stabilizing and removing plutonium-contaminated ventilation ducts, demolishing three structures to grade, and installing an environmental barrier on the demolition site . All of this work was performed safely, on schedule, and under budget. During the deactivation phase of the project between November 2005 and February 2007, workers entered the highly contaminated confined-space tank vaults 428 times. Each entry (or 'dive') involved an average of three workers, thus equaling approximately 1,300 individual confined -space entries. Over the course of the entire deactivation and demolition period, there were no recordable injuries and only one minor reportable skin contamination. The 241-Z D&D Project was decommissioned under the provisions of the 'Hanford Federal Facility Agreement and Consent Order' (the Tri-Party Agreement or TPA), the 'Resource Conservation and Recovery Act of 1976' (RCRA), and the 'Comprehensive Environmental Response, Compensation, and

    Full Text Available Waste management is currently an inherent part of sustainable construction and, thus, sustainable development. Construction and demolition waste is an issue continuously intensifying in every country. The primary object of this paper is to present issues associated with a gap between sustainable building regulations in the United Arab Emirates, and the recycling facilities such as the Bee’ah facility in Sharjah. Existing construction and demolition waste management has been investigated in terms of available literature as well as for construction sites and the precast concrete factory located in Sharjah.

    The Hood River Passive Project was developed by Root Design Build of Hood River Oregon using the Passive House Planning Package (PHPP) to meet all of the requirements for certification under the European Passive House standards. The Passive House design approach has been gaining momentum among residential designers for custom homes and BEopt modeling indicates that these designs may actually exceed the goal of the U.S. Department of Energy's (DOE) Building America program to reduce home energy use by 30%-50% (compared to 2009 energy codes for new homes). This report documents the short term test results of the Shift House and compares the results of PHPP and BEopt modeling of the project.
