    Beauty, utility, durability - these are the features of good architecture and should also be the distinguishing qualities of every residential building. But do beauty and utility remain along with the passing of time? Performance characteristics are an indicator of both, the technical as well as aesthetic state of buildings. Aesthetic needs are in disagreement with the merciless aging process. The beauty of a city is formed not only by the original forms of new residential buildings, but also by existing tenement housing; thus preserving their aesthetics becomes a necessity. Time is continuously passing and along with it, aging intensifies. The aging process is a natural phenomenon for every material. The life expectancy of building materials is also limited. Along with the passing of time, the technical state of residential buildings continuously deteriorates. With the passing of time, the aesthetic values and preferences of users of flats change and the usability of the building decreases. The permanence of buildings, including residential buildings, is shaped not only by the forces of nature but also by activities of humans. A long lifespan is ensured by carrying out ongoing, systematic renovation-repair works. It is thanks to them that buildings derived from past centuries are still being used, and their market attractiveness is not decreasing.

    2014-01-01

    Residential construction is a high-risk industry in the U.S. due to the exposure to work-related safety hazards and fall injuries. This study aimed to examine the safety training and safe work practices of construction workers within the small residential construction industry. In order to achieve the study objectives, a survey was designed and sent to approximately 200 Wisconsin based residential construction contractors. About one third of the respondents stated that they did not have any form of safety programs. The study indicated that the most common types of work-related injuries in residential construction were slips/trips/falls and cuts/lacerations. The survey findings also suggested that the residential construction contractors needed to increase the utilization of fall protection safety equipment. Further education and subject matter expert training could provide benefits to improve occupational safety and health of the small business workforce in the residential construction industry.

  4. Residential construction cost: An Italian survey.

    2017-04-01

    This paper reports data describing development projects for new buildings according to construction costs in North-East Italy. A survey was carried out on local companies undertaking new residential development projects in two Italian regions (Veneto and Lombardy). The aim of this survey was to record new real estate construction projects, collecting both technical and socio-economic cost features. It is extremely difficult to collect such data for the Italian real estate construction sector, due to its lack of transparency, so that the novelty for the Italian scenario is the dataset itself. Another interest perspective of this survey is that socio-economic characteristics were also recorded; they are often studied in urban economics, but are usually related to property purchase prices and values, not to construction costs. The data come from an analysis of Canesi and Marella regarding the relationship between the trend of construction costs and the socio-economic conditions of the reference setting, such as the mean years of schooling of the workforce, housing market trends, and average per capita income.

  6. Research methods of the parameters of residential buildings construction

    Directory of Open Access Journals (Sweden)

    Grigor’ev Vladimir Aleksandrovich

    Full Text Available The analysis of construction theory and practice shows that rational organizational and technological parameters of the construction of residential buildings should be based on the manifestation in time and space of the most important stages construction with their harmonization. Basing on the experience of normalizing the construction duration, it is advisable to express the complex of residential buildings’ construction processes by their basic stages - preparatory period, underground part, aboveground part, external engineering networks and land improvement. The main indicators of the development and implementation of optimization solutions are: the total duration of the construction, the duration of the preparation period, the duration of the construction of the underground part, the duration of the construction of the aboveground part, the duration of external engineering networks laying, the duration of land improvement. The indicators of the total duration of the construction of residential buildings, the construction the underground and aboveground parts are determined on the basis of the operation of one assembly crane on an object of up to four sections. In case of more sections two (three cranes are considered and the total construction duration is set depending on these conditions. The duration of the construction of multisectional buildings is determined basing on the simultaneous construction of the stages or their combination with a certain time shift. However, this approach requires a significant amount of optimization solutions due to its multivariance. Therefore, in order to reduce the volume of calculations in some cases, for example, when planning the development of districts and neighborhoods, statistical methods can be used for determining the duration of the construction basing on the compilation of optimization solutions. The total duration of the construction and the duration of the main stages are multiple

    Full Text Available Residential construction is one of the most important pillars of Iran’s economy. Although this sector had an increasing trend over the past two decades, however, the growth rate of residential construction was very volatile. The purpose of this paper is to empirically investigate those factors contributing to this fluctuation over the 1991:Q2-2008:Q4. By applying cointegration approach, the empirical results show that housing prices, construction costs, GDP and gold prices are important factors to explain swings in residential construction in Iran.

  8. Best practices guide for residential HVAC Retrofits

    Energy Technology Data Exchange (ETDEWEB)

    Walker, Iain S.

    2003-08-11

    This best practices guide for residential HVAC system retrofits is aimed at contractors who want guidance on delivering energy efficient, cost effective and innovative products. It has been developed around the idea of having packages of changes to the building HVAC system and building envelope that are climate and house construction dependent. These packages include materials, procedures and equipment and are designed to remove some of the guesswork from a builder, contractor, installer or homeowner decisions about how best to carry out HVAC changes. The packages are not meant to be taken as rigid requirements--instead they are systems engineered guidelines that form the basis for energy efficient retrofits. Similar approaches have been taken previously for new construction to develop extremely energy efficient homes that are comfortable safe and durable, and often cost less than standard construction. This is best epitomized by the Building America program whose partners have built thousands of residences throughout the U.S. using these principles. The differences between retrofitting and new construction tend to limit the changes one can make to a building, so these packages rely on relatively simple and non-intrusive technologies and techniques. The retrofits also focus on changes to a building that will give many years of service to the occupants. Another key aspect of these best practices is that we need to know how a house is working so that we know what parts have the potential for improvement. To do this we have put together a set of diagnostic tools that combine physical measurements and checklists/questionnaires. The measured test results, observations and homeowner answers to questions are used to direct us towards the best retrofits applicable to each individual house. The retrofits will depend on the current condition of the building envelope and HVAC system, the local climate, the construction methods used for the house, and the presence of various

  9. Identification of potential hazards associated with new residential construction.

    2000-02-01

    There were several advantages and limitations of this observational study. The most important advantage of this study was the opportunity to observe residential construction workers performing their jobs. By observing work practices, valuable information was gathered about specific trades and their potential exposure to various chemical and physical agents. This information will be useful in guiding subsequent exposure assessments. Probably the greatest limitation of this study was the lack of participation by homebuilders. Ideally, observations of construction processes would have been more objective if the study included the participation of more than one homebuilder. Aside from one worker who was observed to wear safety glasses, leather gloves, and a dust mask, virtually no personal protective equipment (PPE) was observed onsite. Often small contractors do not have the financial resources necessary to procure the appropriate PPE and issue these items to the workers. Based on hazard prevalence, professional judgement, and the degree of hazardous product use, potential exposures that warrant quantitative sampling efforts during Phase 2 of this study are: bulldozer/backhoe operators--noise, vibration, diesel exhaust; concrete workers--naphtha, mineral spirits, Portland cement; asphalt workers--petroleum hydrocarbons, asphalt, mineral spirits; plumbers--methylethyl ketone, acetone, tetrahydrofuran, cyclohexanone; drywall finishers--total and respirable dust, hexane, acetone; painters--ethylene glycol, VOCs; masons--dust (during the preparation of mortar); floor preparation technicians--total and respirable dust; and ceramic tile installers--toluene, naphtha, silica (from grout powder).

  10. Greenhouse Gas Emissions from Excavation on Residential Construction Sites

    2014-12-01

    Full Text Available Despite considerable research concerning the manifestation of greenhouse gases in the usage of buildings, little has been done concerning emissions arising from the construction process itself. This paper specifically examines emissions arising from cut and fill excavation on residential construction sites. Even though such excavation is often seen as being economical in terms of providing a flat base for concrete raft slab construction, the environmental consequences of this approach need to be considered more fully in terms of impact on the environment. This is particularly important when steeply sloping sites are involved and for different soil types. The paper undertakes a study that quantitatively assesses the cumulative greenhouse gas emissions caused by cut and fill excavation on 52 residential projects in Australia for a range of slope and soil types. The paper presents results from the study and concludes that greenhouse gas emissions increase as site slope increases; the building footprint area (as distinct from Gross Floor Area, exposes the need to reduce the area of the building to reduce greenhouse gas emissions; excavation of rock soils creates higher emissions than other soil types; and cut and fill excavation on steeply slope sites increase emissions. Potential alternative construction includes suspended floor construction systems which involve less excavation.

    This report for the International Energy Agency (IEA) made by Task 10 of the Photovoltaic Power Systems (PVPS) programme takes a look at urban building-integrated photovoltaics (BIPV) in the new residential construction industry. 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. The report states that different types of building require different approaches to BIPV due to their associated varying dimensions and geometry. Several solutions are proposed to encourage the adoption and diffusion of BIPV by the new home residential building industry. These are divided into PV industry-based approaches and policy-based solutions. The former include end-customer focused policies, the identification of early adopters, the creation of product solutions that meet the needs of the building industry and standards and that the construction industry must be engaged in the design and planning stage of residential developments. Policy questions discussed include the provision of incentives, a planned approach to the demonstration of BIPV and the development of BIPV-specific policy.

    Sevenson Environmental Services, Inc., (Sevenson) has performed several radiological remediation projects located in residential urban areas. Over the course of these projects, there has been a wide variety of experiences encountered from construction related issues to unique social situations. Some of the construction related issues included the remediation of interior basements where contaminated material was located under the footers of the structure or was used in the mortar between cinder block or field stone foundations. Other issues included site security, maintaining furnaces or other utilities, underpinning, backfilling and restoration. In addition to the radiological hazards associated with this work there were occupational safety and industrial hygiene issues that had to be addressed to ensure the safety and health of neighboring properties and residents. The unique social situations at these job sites have included arson, theft/stolen property, assault/battery, prostitution, execution of arrest warrants for residents, discovery of drugs and paraphernalia, blood borne pathogens, and unexploded ordnance. Some of these situations have become a sort of comical urban legend throughout the organization. One situation had historical significance, involving the demolition of a house to save a tree older than the Declaration of Independence. All of these projects typically involve the excavation of early 20. century items such as advertisement signs, various old bottles (milk, Listerine, perfume, whisky) and other miscellaneous common trash items.

    For the formation of programs for housing construction and planning of capital investments, when developing the strategic planning companies by construction companies, the norms or calculated indicators of the duration of the construction of high-rise residential buildings and multifunctional complexes are mandatory. Determination of stable values of the parameters for the high-rise construction residential buildings provides an opportunity to establish a reasonable duration of construction at the planning and design stages of residential complexes, taking into account the influence of market conditions factors. The concept of the formation of enlarged models for the high-rise construction residential buildings is based on a real mapping in time and space of the most significant redistribution with their organizational and technological interconnection - the preparatory period, the underground part, the above-ground part, external engineering networks, landscaping. The total duration of the construction of a residential building, depending on the duration of each redistribution and the degree of their overlapping, can be determined by one of the proposed four options. At the same time, a unified approach to determining the overall duration of construction on the basis of the provisions of a streamlined construction organization with the testing of results on the example of high-rise residential buildings of the typical I-155B series was developed, and the coefficients for combining the work and the main redevelopment of the building were determined.

  20. Impacts of an Innovative Residential Construction Method on Internal Conditions

    Directory of Open Access Journals (Sweden)

    Roger Birchmore

    2015-02-01

    Full Text Available New Zealand houses are known for producing sub-optimal internal thermal conditions and unacceptably high internal moisture levels. These contribute to poor levels of health, mould and can coincide with the decay of structural timber frames. A proposed solution is to provide an alternative structure utilising plywood, a vapour check on the internal face of the timber frame and an additional air gap, followed by the internal lining. The internal vapour check is designed to prevent moisture vapour diffusion from inside into the frame and to permit moisture diffusion from outside through the structure to the internal environment. Two full scale houses had temperatures, dew points and humidity levels monitored in passive, unoccupied conditions. The test case house incorporated the innovative construction solution. The control house was of identical design and location, using standard construction practice. The calculated internal moisture content profile appeared to be unrelated to the external moisture content as expected, instead following the profile of the changing internal temperature. Whilst the innovative construction appeared to prevent moisture diffusion into the structure in winter and permit it inside in summer, this resulted in a generally higher internal relative humidity than the control house.

  1. A new approach for modelling variability in residential construction projects

    Directory of Open Access Journals (Sweden)

    Mehrdad Arashpour

    2013-06-01

    Full Text Available The construction industry is plagued by long cycle times caused by variability in the supply chain. Variations or undesirable situations are the result of factors such as non-standard practices, work site accidents, inclement weather conditions and faults in design. This paper uses a new approach for modelling variability in construction by linking relative variability indicators to processes. Mass homebuilding sector was chosen as the scope of the analysis because data is readily available. Numerous simulation experiments were designed by varying size of capacity buffers in front of trade contractors, availability of trade contractors, and level of variability in homebuilding processes. The measurements were shown to lead to an accurate determination of relationships between these factors and production parameters. The variability indicator was found to dramatically affect the tangible performance measures such as home completion rates. This study provides for future analysis of the production homebuilding sector, which may lead to improvements in performance and a faster product delivery to homebuyers.

    Vine, E.

    1995-08-01

    Based on an evaluation of 10 residential new construction programs, primarily sponsored by investor-owned utilities in the United States, we find that many of these programs are in dire straits and are in danger of being discontinued because current inclusion of only direct program effects leads to the conclusion that they are not cost-effective. We believe that the cost-effectiveness of residential new construction programs can be improved by: (1) promoting technologies and advanced building design practices that significantly exceed state and federal standards; (2) reducing program marketing costs and developing more effective marketing strategies; (3) recognizing the role of these programs in increasing compliance with existing state building codes; and (4) allowing utilities to obtain an ``energy-savings credit`` from utility regulators for program spillover (market transformation) impacts. Utilities can also leverage their resources in seizing these opportunities by forming strong and trusting partnerships with the building community and with local and state government.

    2013-05-01

    The unfortunate economic situation involving Spain and the European Union is, among other factors, the result of intensive construction activity over recent years. The excessive consumption of natural resources, together with the impact caused by the uncontrolled dumping of untreated C&D waste in illegal landfills have caused environmental pollution and a deterioration of the landscape. The objective of this research was to generate a selective classification and quantification model of C&D waste based on the material resources consumed in the construction of residential buildings, either new or renovated, namely the Conventional Constructive Model (CCM). A practical example carried out on ten residential buildings in Seville, Spain, enabled the identification and quantification of the C&D waste generated in their construction and the origin of the waste, in terms of the building material from which it originated and its impact for every m(2) constructed. This model enables other researchers to establish comparisons between the various improvements proposed for the minimization of the environmental impact produced by building a CCM, new corrective measures to be proposed in future policies that regulate the production and management of C&D waste generated in construction from the design stage to the completion of the construction process, and the establishment of sustainable management for C&D waste and for the selection of materials for the construction on projected or renovated buildings.

    2012-02-01

    The management planning of construction and demolition (C&D) waste uses a single indicator which does not provide enough detailed information. Therefore the determination and implementation of other innovative and precise indicators should be determined. The aim of this research work is to improve existing C&D waste quantification tools in the construction of new residential buildings in Spain. For this purpose, several housing projects were studied to determine an estimation of C&D waste generated during their construction process. This paper determines the values of three indicators to estimate the generation of C&D waste in new residential buildings in Spain, itemizing types of waste and construction stages. The inclusion of two more accurate indicators, in addition to the global one commonly in use, provides a significant improvement in C&D waste quantification tools and management planning.

    Construction industry is an important sector that contributes to the development of economy and socioeconomy in Malaysia. It is a vital component in achieving the developed country status. However, fatalities in the Malaysian construction industry are a critical problem. Number of fatalities in this industry is the highest compared to other industries registered in Malaysia under the investigation of Department of Occupational Safety and Health (DOSH). Worksite element (worksite conditions, poor site management, construction tasks, and equipment & materials) was identified as one category of causes of occupational accidents and illnesses in Malaysian construction industry. The main objective of this study is to understand the perception of local construction personnel in terms of worksite element as causes of occupational accidents and illnesses in Malaysian residential construction industry. 13 housing projects that were registered with Ministry of Urban Wellbeing, Housing and Local Government and being permitted to perform construction work in 2012 were selected in Pulau Pinang to be studied using questionnaire survey. Worksite condition and poor site management was perceived as the most significant with the mean values of 3.68 and 3.61 respectively.

  18. Assessing construction innovation: theoretical and practical perspectives

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available Innovation is key for productivity improvement and advancements in different sectors of the economy, including the construction sector.  The criticism of the slow pace of innovation in construction industry may be unwarranted, considering the structure of the industry and nature of the construction business.  The loosely coupled nature of firms, mostly Small and Medium Enterprises (SME’s, delivering ‘projects’ through partial engagement, together with the distinction between the project innovation and firm innovation makes it difficult to extract innovations in a meaningful way.  The problem also lies in conceptualising, defining, articulating and assessing innovation in construction.  The literature is replete with research into construction innovation, however, there is limited research into understanding how innovation is perceived and narrated in practice.  The paper aims to explore how innovation is assessed and narrated in construction, specifically analysing theory and practice perspectives.  A theoretical model was constructed from a structured literature review illustrating existing discourse and narratives of construction innovation assessment.  A qualitative analysis of ‘Professional Excellence in Building’ submission documents to the Australian Institute of Building was performed to identify the practice perspective of innovation.  The findings suggest that internal organizational and process innovation account for the majority of improvements identified.  Importantly a taxonomy of narrative is developed that articulates how the construction industry in Australia views industry innovation.

    Falls are the leading cause of fatalities in construction. The Safety Pays, Falls Cost campaign aims to prevent falls in residential construction. A critical component of our social marketing approach was to involve 70 partners in reaching target audiences. We assessed partner engagement April 2012-August 2013 through: (1) baseline partnership quality interviews (eight partners); (2) pre-/post-partner "market" readiness in-depth interviews (three partners); (3) a pre-/post- (29/31 partners) online partner engagement survey; and (4) standardized metrics to measure partner activity. We found a high level of interest and engagement that increased with the addition of prompting to action through regular communication and new resources from organizers and formation of local partnerships that were able to tailor their activities to their own communities or regions. It is feasible to leverage government-labor-management partnerships that enjoy trust among target audiences to widely disseminate campaign materials and messages. © 2015 Wiley Periodicals, Inc.

  3. Economics of residential gas furnaces and water heaters in United States new construction market

    Energy Technology Data Exchange (ETDEWEB)

    Lekov, Alex B.; Franco, Victor H.; Wong-Parodi, Gabrielle; McMahon, James E.; Chan, Peter

    2009-05-06

    New single-family home construction represents a significant and important market for the introduction of energy-efficient gas-fired space heating and water-heating equipment. In the new construction market, the choice of furnace and water-heater type is primarily driven by first cost considerations and the availability of power vent and condensing water heaters. Few analysis have been performed to assess the economic impacts of the different combinations of space and water-heating equipment. Thus, equipment is often installed without taking into consideration the potential economic and energy savings of installing space and water-heating equipment combinations. In this study, we use a life-cycle cost analysis that accounts for uncertainty and variability of the analysis inputs to assess the economic benefits of gas furnace and water-heater design combinations. This study accounts not only for the equipment cost but also for the cost of installing, maintaining, repairing, and operating the equipment over its lifetime. Overall, this study, which is focused on US single-family new construction households that install gas furnaces and storage water heaters, finds that installing a condensing or power-vent water heater together with condensing furnace is the most cost-effective option for the majority of these houses. Furthermore, the findings suggest that the new construction residential market could be a target market for the large-scale introduction of a combination of condensing or power-vent water heaters with condensing furnaces.

    Kadulski, R

    This paper discusses the results of a nationwide builder survey on common building techniques, such as framing, insulation, airtight construction practices, testing for airtightness, windows, furnaces and water heaters, and ventilation. Results indicate that changes in construction were mainly influenced by the R-2000 program. The spread of R-2000 technology is reflected in the use of higher insulation levels than are called for by codes or than is normal practice, sealing of joints, and attention to air and vapour retarders as well as air tight drywall techniques combined with mechanical ventilation systems.

    2015-08-01

    A nonprofit primary care, substance abuse and mental health treatment provider that operates nine separate residential treatment facilities in both northern and southern California began allowing clients to keep their mobile phones while in treatment. From the advent of mobile phone technology and its widespread adoption through early 2013, the organization prohibited clients from having phones while in treatment. Calls to and from clients needed to be made and received at the house phone. After years of enforcing the policy with diminished success as phones became cheaper, smaller, and more prevalent, agency leadership decided to experiment with allowing the clients to keep their phones while in treatment. Elopement data as they relate to the policy are examined along with data from staff interviews about its implementation and impact. Results show that elopements resulting from being caught with a mobile phone were eliminated and some clients were able to be returned to treatment using the devices. All seven (100%) of the interviewees were supportive of the new policy and thought it should be continued. The impact of the policy on clinical disruptions, lost/stolen property liability, and confidentiality issues are discussed. Copyright © 2015 Elsevier Inc. All rights reserved.

    Eight percent of Australians aged 65 years and over receive residential aged care each year. Residents are increasingly older, frailer and have complex care needs on entry to residential aged care. Up to 63% of Australian residents of aged care facilities take nine or more medications regularly. Together, these factors place residents at high risk of adverse drug events. This paper reviews medication-related policies, practices and research in Australian residential aged care. Complex processes underpin prescribing, supply and administration of medications in aged care facilities. A broad range of policies and resources are available to assist health professionals, aged care facilities and residents to optimise medication management. These include national guiding principles, a standardised national medication chart, clinical medication reviews and facility accreditation standards. Recent Australian interventions have improved medication use in residential aged care facilities. Generating evidence for prescribing and deprescribing that is specific to residential aged care, health workforce reform, medication-related quality indicators and inter-professional education in aged care are important steps toward optimising medication use in this setting.

    2014-06-01

    Full Text Available In order to prolong the life of the old buildings in the country through building conservation practices, there is a tendency by the government to acquire and reuse Malaysian leadership figures’ residential buildings as memorials. However, it raises the question of whether there is any adaptive reuse guidelines to reuse historic residential buildings in Malaysia as national memorials in maintaining those buildings as an exhibition space on the history of their leadership. The absence of guidelines raises questions about how to implement the process accordingly. The objective of this research is to find the best formula for reusing historic residential buildings as national memorials based on that issue by reviewing and identify the principles of adaptive reuse practices of historic residential buildings as national memorials that implemented in Malaysia. The case studies were conducted on three samples of historic residential buildings that reused as national memorials and those buildings were selected based on a list of the study population, which are Rumah Kelahiran Tun Dr. Mahathir Mohamad (The Birthplace of Tun Dr. Mahathir Mohamad, Rumah Merdeka (Freedom House and Memorial Tun Abdul Ghafar Baba (The Tun Abdul Ghafar Baba Memorial. The sample may be determined by the sampling method and evaluated using the checklist provided. Based on the results of the case studies that were analyzed and discussed, it can be concluded that aspects of building code (local requirements as well as environmental and conservation requirements are not met in implementing adaptive reuse process on historic residential buildings to national memorials which needs suggestions for improvement.

    Masso, Malcolm; McCarthy, Grace; Kitson, Alison

    2014-07-01

    The context for the study was a nation-wide programme in Australia to implement evidence-based practice in residential aged care, in nine areas of practice, using a wide range of implementation strategies and involving 108 facilities. The study drew on the experiences of those involved in the programme to answer the question: what mechanisms influence the implementation of evidence-based practice in residential aged care and how do those mechanisms interact? The methodology used grounded theory from a critical realist perspective, informed by a conceptual framework that differentiates between the context, process and content of change. People were purposively sampled and invited to participate in semi-structured interviews, resulting in 44 interviews involving 51 people during 2009 and 2010. Participants had direct experience of implementation in 87 facilities, across nine areas of practice, in diverse locations. Sampling continued until data saturation was reached. The quality of the research was assessed using four criteria for judging trustworthiness: credibility, transferability, dependability and confirmability. Data analysis resulted in the identification of four mechanisms that accounted for what took place and participants' experiences. The core category that provided the greatest understanding of the data was the mechanism On Common Ground, comprising several constructs that formed a 'common ground' for change to occur. The mechanism Learning by Connecting recognised the ability to connect new knowledge with existing practice and knowledge, and make connections between actions and outcomes. Reconciling Competing Priorities was an ongoing mechanism whereby new practices had to compete with an existing set of constantly shifting priorities. Strategies for reconciling priorities ranged from structured approaches such as care planning to more informal arrangements such as conversations during daily work. The mechanism Exercising Agency bridged the gap between

    Cogurcu, M. T.

    2015-04-01

    Turkey is situated in a very active earthquake region. In the last century, several earthquakes resulted in thousands of deaths and enormous economic losses. In 1999, the Kocaeli earthquake had an approximate death toll of more than 20 000, and in 2011 the Van earthquake killed 604 people. In general, Turkish residential buildings have reinforced concrete structural systems. These reinforced concrete structures have several deficiencies, such as low concrete quality, non-seismic steel detailing and inappropriate structural systems including several architectural irregularities. In this study, the general characteristics of Turkish building stock and the deficiencies observed in structural systems are explained, and illustrative figures are given with reference to the Turkish Earthquake Code 2007. The poor concrete quality, lack of lateral or transverse reinforcement in beam-column joints and column confinement zones, high stirrup spacings, under-reinforced columns and over-reinforced beams are the primary causes of failures. Other deficiencies include weak-column-stronger-beam formations, insufficient seismic joint separations, soft-story or weak-story irregularities and short columns. Similar construction and design mistakes are also observed in other countries situated on active earthquake belts. Existing buildings still have these undesirable characteristics, and so to prepare for future earthquakes they must be rehabilitated.

    Blaine, Thomas W; Clayton, Susan; Robbins, Paul; Grewal, Parwinder S

    2012-08-01

    This study describes the results of a survey of 432 homeowners in Ohio, USA concerning their perceptions and practices regarding management of residential landscapes. The results reveal that outdoor residential environments are extremely important to homeowners, who tend to view their yards as serving multiple functions: a place to observe nature and to socialize as well as a place of beauty and recreation. Use of a lawn care company to apply chemicals is reported by 22 % of respondents, while 40 % either apply chemicals themselves or have someone other than a lawn care company do it. Logistic regressions reveal that factors influencing a homeowner's decision to employ a lawn care company or to apply chemicals themselves include: household income (+), perceived impacts on the environment (-), whether the next door neighbor does it (+), and type of residential environment (rural -, suburban and urban +). A theme that emerges throughout the study is the perceived importance of the role of the lawn in residents' sense of social status or acceptance in the neighborhood. This perception can be viewed as a positive in ensuring that residential environments are well maintained, but also as a negative resulting in environmental degradation or presenting a barrier to creativity in the development of alternative residential environments. Specific policy implications of these findings are that efforts aimed at educating homeowners about the environmental impacts of their lawn care choices are likely to have more success if they are directed at neighborhood groups rather than individuals, show that alternatives are easy to adopt, affordable, and can produce the characteristics of lawns that homeowners seek.

    2008-06-01

    Background  Continence Management within residential aged care is an every day component of care that requires assessment, implementation of strategies, resource allocation and evaluation. At times the management of incontinence of aged residents can be challenging and unsuccessful. The project chosen through the Clinical Fellowship program was Continence Management with the aim of raising awareness of best practice to assist in improving and providing person-centred resident care. Aims/objectives •  Review the literature on best practice management of incontinence •  Evaluate current practice in continence management for elderly residents within residential aged care services •  Improve adherence to best practice strategies of care for incontinence •  Raise awareness within the nursing home of the best practice management of incontinence •  Promote appropriate and effective use of resources for continence management •  Deliver individualised person-centred care to residents. •  Ensure best practice in continence management Methods  The Joanna Briggs Institute (JBI) Practical Application of Clinical Evidence System clinical audit tool was utilised to measure current practice against best practice. The results identify gaps that require improvement. The Getting Research into Practice process then allowed analysis of the level of compliance with each of the audit criteria, which would identify any barriers in implementing a selected course of action and aim to improve compliance. The project team was consulted with additional stakeholder consultation to form an action plan and implement strategies to improve practice. Results  Although 100% compliance with all audit criteria in audit 1 and 2 was not achieved, there was improvement in the criteria concerning the documented fluid intake for residents. Further strategies have been identified and implemented and this continues to be a 'work in progress'. Staff now have an acute awareness

    2015-09-01

    Full Text Available Sustainable development in construction is based on three fundamental pillars: economic, environmental and social. This type of approach aims to identify the best possible solutions for sustainably developing structures by conducting a joint evaluation of the impact on those three pillars. The proposed methodology incorporates metadata on the Spanish construction sector. First, a discrete database is generated with 360 alternatives covering a range of common solutions in residential building. A Pareto algorithm is utilized to select the optimal choices and the wide range of solutions is reduced to the 5 % of the initial group. The project manager is therefore provided with an objective assessment of suitable structural alternatives including the overall joint economic, social, and environmental impact. The results obtained demonstrate the importance and utility of the proposed methodology for sustainable construction.El desarrollo sostenible aplicado a la construcción se basa en tres pilares fundamentales: económico, medioambiental y social. El objetivo principal es identificar las mejores soluciones en términos de desarrollo sostenible de alternativas estructurales a partir de la evaluación conjunta de los impactos en dichos pilares. La metodología propuesta incorpora metadatos con información del sector de la construcción en España. Primero se genera una base de datos discreta de 360 alternativas estructurales que cubren el rango de soluciones habituales en edificación residencial. La selección de alternativas óptimas se realiza mediante el algoritmo de Pareto. El abanico de soluciones se reduce al 5 % de las iniciales. Se aporta una valoración objetiva que orienta al proyectista en la selección de alternativas estructurales idóneas, visualizando de forma conjunta el impacto económico, social y ambiental. Los resultados obtenidos muestran la importancia y utilidad de la metodología propuesta en el campo de la construcci

    2015-06-01

    Conscience can be perceived as an asset that helps care providers to provide good care, but it can also be a burden that generates stress of conscience (stress related to a troubled conscience). Participatory action research (PAR) has been shown to be successful in supporting care providers in residential care of older people to learn to deal with their troubled conscience in challenging and demanding care situations. The aim of the study was to describe an intervention process to assist care providers in residential care of older people to constructively deal with their troubled conscience related to perceptions of deficient teamwork. The study design was grounded in PAR. Nine enrolled nurses (ENs), two nursing aids (NAs), one Registered Nurse (RN) and their manager participated in 12 PAR sessions. All sessions were tape-recorded, and a domain analysis of the transcriptions was performed. Findings show that a PAR-based intervention can support care providers to understand, handle and take measures against deficient teamwork. Using troubled conscience as a driving force can increase the opportunities to improve quality of care in residential care for older people. During the PAR process, participants raised their awareness of the need to view the team in a wider sense and that the manager and the Registered Nurse should also be members of the team to improve team outcome. To improve clinical practice, we suggest that teams in residential care of older people should be enabled to share and reflect on challenging situations that generate troubled conscience. However, as shown in this study, care providers might need support in order to facilitate and promote sharing and reflecting on what their conscience tells them. © 2014 Nordic College of Caring Science.

  20. Fall prevention and safety communication training for foremen: report of a pilot project designed to improve residential construction safety.

    2013-02-01

    Falls from heights account for 64% of residential construction worker fatalities and 20% of missed work days. We hypothesized that worker safety would improve with foremen training in fall prevention and safety communication. Training priorities identified through foreman and apprentice focus groups and surveys were integrated into an 8-hour training. We piloted the training with ten foremen employed by a residential builder. Carpenter trainers contrasted proper methods to protect workers from falls with methods observed at the foremen's worksites. Trainers presented methods to deliver toolbox talks and safety messages. Results from worksite observational audits (n=29) and foremen/crewmember surveys (n=97) administered before and after training were compared. We found that inexperienced workers are exposed to many fall hazards that they are often not prepared to negotiate. Fall protection is used inconsistently and worksite mentorship is often inadequate. Foremen feel pressured to meet productivity demands and some are unsure of the fall protection requirements. After the training, the frequency of daily mentoring and toolbox talks increased, and these talks became more interactive and focused on hazardous daily work tasks. Foremen observed their worksites for fall hazards more often. We observed increased compliance with fall protection and decreased unsafe behaviors during worksite audits. Designing the training to meet both foremen's and crewmembers' needs ensured the training was learner-centered and contextually-relevant. This pilot suggests that training residential foremen can increase use of fall protection, improve safety behaviors, and enhance on-the-job training and safety communication at their worksites. Construction workers' training should target safety communication and mentoring skills with workers who will lead work crews. Interventions at multiple levels are necessary to increase safety compliance in residential construction and decrease falls

  1. Influence of Handling Practices on Material Recovery from Residential Solid Waste

    2010-07-01

    Full Text Available Material recovery from municipal solid waste (MSW is becoming widely adopted in several developing countries. Residential solid waste is one of the most important components of MSW and the handling practices of the MSW by the generators have a major impact on the quality and quantity of the materials for recovery. This article analyzes the generation and composition of residential solid waste and the handling practices by users in three municipalities in Colombia that have a solid waste management plant (SWMP. The findings show that, although there are significant amounts of useful materials, their handling of the materials as “garbage”, the low recognition of recovery work, and the inadequate storage and source management practices, affect material recovery and the operation of SWMPs. These results may be taken as a reference for this type of municipality, because the solid waste management system and the type of operation of the SWMPs analyzed is similar to all of the SWMPs in the country as well as in other countries in the region.

    A total of 31,113 workers' compensation claims among 7,400 North Carolina Homebuilders Association (NCHA) members and their subcontractors for the period 1986-1994 were analyzed to calculate workers' compensation claim incidence density rates. For the 7 years studied, the average rate (cases/200,000 work hours) for all claims was 16.40 and the rate for medical or lost time cases was 10.78. Highest rates for cases involving medical costs or paid lost time by mechanism of injury were observed for being struck by an object (3.1), lifting/movement (1.97), falls from a different level (1.13), striking against an object (0.87), and falls on the same level (0.46). Rates by mechanism of injury were highest for muscle strains (2.34), wounds/punctures (2.33), bruises/contusions (1.24), fractures/dislocations (0.98), and injuries to the eyes (0.81). Among medical cost or lost work time cases, body parts with highest injury rates were back/shoulders (1.99), fingers (1.31), leg/knee (1.00), hand/wrist (1.00), foot/ankle (0.86), and eyes (0.82). Injury rates were found to vary substantially among the residential construction trades. For more serious injuries involving medical costs greater than $2,000 or any lost work time, rates were highest for welders and cutters (28.1), insulators (24.3), roofers (19.4), and carpenters (15.3). The same general trends by trade were observed for cases involving paid lost time except that roofers were highest, with a rate of 9.1, followed by insulators (8.5), welders and cutters (5.8), and carpenters (5.8). Rates of falls from a different level resulting in medical costs or lost work time were highest for roofers (5.54), insulators (3.53), carpenters (2.05), and drywall installers (1.99). Descriptive information for falls from a different level resulting in paid lost time during 1993-1994 (n = 219) were reviewed to better determine the causes and circumstances of injuries. Falls from a roof accounted for 25.4 percent of the cases followed by

  3. Modernizing residential heating in Russia: End-use practices, legal developments, and future prospects

    2012-01-01

    This article explores the significance of modernization policies concerning Russia’s technically obsolete but socially important residential heating sector, focusing on the 2009 energy efficiency framework law and its prospects for implementation. Ownership and control structures are in flux throughout the heating sector chain. Inefficiencies, causing low service quality and rising prices, have already started eroding the market share of district heating, despite its potential benefits. End-use management practices – such as lack of metering, communal billing, and low prices that do not cover production costs – reduce consumer incentives to cut consumption. The diversity of end-users adds to the complexity of focused measures like energy-saving contracts. However, end-use sector reforms such as mandatory meter installation and increasing prices – even if socially acceptable and fully implemented – cannot alone provide the massive investments required. More appropriate is sector-wide reform with the government’s financial participation – especially if consumer efforts can yield better service quality. - Highlights: ► We analyze Russia’s energy efficiency policy on residential heating sector. ► Institutional structures and practices reduce incentives to cut consumption. ► Meter installation and increasing prices cannot deliver investments required. ► Government led sector-wide reform is required, linked to better service quality.

    We hypothesised that a key factor determining the quality of active support was 'practice leadership' - provided by the first-line manager to focus staff attention and develop staff skills in providing direct support to enable people with intellectual disabilities to have a good quality of life. This exploratory study focused on what levels of practice leadership were found and its role in explaining variation in active support. Relevant aspects of management, including practice leadership, were assessed by questionnaires administered to staff in residential settings alongside observational measures of active support and resident engagement in meaningful activity. Relationships between these variables were explored using regression and post hoc group comparisons. There was wide variation, with average levels of practice leadership being low, though improving over the period studied. Practice leadership had a significant impact on active support, but was fully mediated by the effect of quality of management. When the quality of management was higher better practice leadership did produce a significant difference in active support. However, higher quality of management on its own did not produce better active support. A number of limitations are acknowledged and further research is required. Practice leadership appears to be an important factor in enabling staff to provide active support but as part of generally good management. Given the rather low levels found, attention needs to be given to the training, career development and support of practice leaders and also to how to protect their time from their many other responsibilities. © 2013 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    Stormwater ponds are installed in urban developments to provide the ecosystem services of flood control and water treatment. In coastal areas, these ponds are connected to watersheds that can drain directly into protected estuaries, making their design, function, and maintenance critical to environmental protection. However, stormwater ponds in residential areas are increasingly managed as aesthetic amenities that add value to real estate rather than as engineered devices with special maintenance requirements. To help extend the life of neighborhood stormwater systems and improve ecosystem services, homeowners should follow best management practices for nutrient management and add shoreline plantings and non-invasive, beneficial aquatic plants to their ponds. This study used focus group and survey research to document the knowledge, behaviors, and attitudes of homeowners living near stormwater ponds in a master-planned community in Florida. The study was designed to use a social marketing research approach to promote Extension best practices. Findings indicate that many residents were aware of the functional components of stormwater systems and respondents' receptivity to best management practices was mediated by age, their attitudes about water quality and whether their home was adjacent to a pond. These findings can be used to target Extension audiences and improve adoption of stormwater pond best management practices for increased protection of water quality.

    To report on the development of a framework of narrative practice, in residential care settings for older people. Residential care settings for older people provide care for people who are no longer able to live in their own home. To date, the impact and structure of nursing practice on care provision in these settings has proved difficult to conceptualise within a specific nursing theory framework. A hermeneutic approach incorporating narrative methods was used. Forty-six narrative interviews with older people in residential care were secondary-analysed for key themes through a three-stage process: by the first author, four focus groups of 12 clinical nurse managers and two independent experts. Themes were also derived from a focus group of eight residents who explored person-centredness and narrative. Finally, the combined findings were used to derive a single set of themes. The secondary data analysis process led to the development of a framework of narrative practice for the care of older people in residential settings. The framework is influenced by narrative enquiry, person-centred practice and practice development. It has four pillars, prerequisites, care processes, care environment and narrative aspects of care. To operationalise the framework of narrative practice, three narrative elements, narrative knowing, narrative being and narrative doing, need to be considered. Working with the foundational pillars and the narrative elements would enable staff to 'work in a storied way' and provide person-centred outcomes and a narrative informed philosophy of care for older adults in residential care. This framework provides nurses with a template that confirms the identity of the older person taking account of their biography. The framework outlines an approach that provides staff with a template on how to provide person-centred care in a narrative way. © 2013 John Wiley & Sons Ltd.

    Despite the institution of explicit safety practices in construction, there continue to be exceedingly high rates of morbidity and mortality from work-related injury. This study's purpose was to identify, compare and contrast views of construction managers from large and small firms regarding construction safety practices. A complementary analysis was conducted with construction workers. A semi-structured interview guide was used to elicit information from construction managers (n = 22) in a series of focus groups. Questions were designed to obtain information on direct safety practices and indirect practices such as communication style, attitude, expectations, and unspoken messages. Data were analyzed using thematic content analysis. Managers identified a broad commitment to safety, worker training, a changing workplace culture, and uniform enforcement as key constructs in maintaining safe worksites. Findings indicate that successful managers need to be involved, principled, flexible, and innovative. Best practices, as well as unsuccessful injury prevention programs, were discussed in detail. Obstacles to consistent safety practice include poor training, production schedules and financial constraints. Construction managers play a pivotal role in the definition and implementation of safety practices in the workplace. In order to succeed in this role, they require a wide variety of management skills, upper management support, and tools that will help them instill and maintain a positive safety culture. Developing and expanding management skills of construction managers may assist them in dealing with the complexity of the construction work environment, as well as providing them with the tools necessary to decrease work-related injuries.

    The ancient cultures of the Americas were separated by thousands of miles and thousand of years. There was a long history of trade over the miles and the years with many shared cultural ideals and artifacts, as evidenced by their musical instruments. Flutes were the most prevalent instruments found throughout the ancient Americas. Some types are unique to the pre-Hispanic world. Although flutes were constructed from a variety of materials, including bone, cane, seed pods, skulls, it is primarily the ceramic ones that survived, and it is ceramic flutes which form the bulk of this writer's work and research. This paper includes musical demonstrations to show how ancient flutemakers could have manipulated timbre during construction. Clay's plasticity enabled the construction of some instruments, and limited the development of others. Pitch jump flutes, certain Veracruzano whistles, and chamberduct flutes and whistles all share the addition of clay flaps or chambers around the aperture, as do hooded pipes. Some instruments exhibit a seemingly cultural predilection for complex tones that are windy, raspy, or animalistic. Simple adjustments of the airduct promote these timbres. Also included will be samples of the original sounds of ancient flutes.

    2016-01-01

    Full Text Available The construction industry is increasingly concerned with improving the social, economic, and environmental indicators of sustainability. More than ever, the growing demand for construction materials reflects increased consumption of raw materials and energy, particularly during the phases of extraction, processing, and transportation of materials. This work aims to help decision-makers and to promote life cycle thinking in the construction industry. For this purpose, the life cycle assessment (LCA methodology was chosen to analyze the environmental impacts of building materials used in the construction of a residence project in São Gonçalo, Rio de Janeiro, Brazil. The LCA methodology, based on ISO 14040 and ISO 14044 guidelines, is applied with available databases and the SimaPro program. As a result, this work shows that there is a substantial waste of nonrenewable energy, increasing global warming and harm to human health in this type of construction. This study also points out that, for this type of Brazilian construction, ceramic materials account for a high percentage of the mass of a total building and are thus responsible for the majority of environmental impacts.

    2008-01-01

    Data developed by the Consortium for Research on Renewable Industrial Materials were used to estimate savings of greenhouse gas emissions and energy consumption associated with use of wood-based building materials in residential construction in the United States. Results indicate that houses with wood-based wall systems require 15-16% less total energy for non-heating/cooling purposes than thermally comparable houses employing alternative steel- or concrete-based building systems. Results for non-renewable energy consumption are essentially the same as those for total energy, reflecting the fact that most of the displaced energy is in fossil fuels. Over a 100-year period, net greenhouse gas emissions associated with wood-based houses are 20-50% lower than emissions associated with thermally comparable houses employing steel- or concrete-based building systems. Assuming 1.5 million single-family housing starts per year, the difference between wood and non-wood building systems represents about 9.6 Mt of CO 2 equivalents per year. The corresponding energy benefit associated with wood-based building materials is approximately 132 PJ year -1 . These estimates represent about 22% of embodied energy and 27% of embodied greenhouse gas emissions in the residential sector of the US economy. The results of the analysis are very sensitive to assumptions and uncertainties regarding the fate of forestland that is taken out of wood production due to reduced demand for wood, the continued production of co-products where demand for wood products is reduced, and the rate at which carbon accumulates in forests

    2014-01-01

    Full Text Available The function of minimization of construction solid waste is to reduce or eliminates the adverse impacts on the environment and to human health. Due to the increase of population that leads to rapid development, there are possibilities of construction solid waste to be increased shortly from the construction works, demolition or renovation works. Materials such as wood, concrete, paint, brick, roofing, tiles, plastic and any other materials would contribute problem involving construction solid waste. Therefore, the proper waste minimization is needed to control the quantity of construction solid waste produced. This paper identifies the type of construction solid waste produced and discusses the waste minimization practice by the contractors at construction sites in Selangor, Kuala Lumpur and Putrajaya, Malaysia.

  5. Locally Simple Models Construction: Methodology and Practice

    2017-12-01

    Full Text Available One of the most notable trends associated with the Fourth industrial revolution is a significant strengthening of the role played by semantic methods. They are engaged in artificial intelligence means, knowledge mining in huge flows of big data, robotization, and in the internet of things. Smart contracts also can be mentioned here, although the ’intelligence’ of smart contracts still needs to be seriously elaborated. These trends should inevitably lead to an increased role of logical methods working with semantics, and significantly expand the scope of their application in practice. However, there are a number of problems that hinder this process. We are developing an approach, which makes the application of logical modeling efficient in some important areas. The approach is based on the concept of locally simple models and is primarily focused on solving tasks in the management of enterprises, organizations, governing bodies. The most important feature of locally simple models is their ability to replace software systems. Replacement of programming by modeling gives huge advantages, for instance, it dramatically reduces development and support costs. Modeling, unlike programming, preserves the explicit semantics of models allowing integration with artificial intelligence and robots. In addition, models are much more understandable to general people than programs. In this paper we propose the implementation of the concept of locally simple modeling on the basis of so-called document models, which has been developed by us earlier. It is shown that locally simple modeling is realized through document models with finite submodel coverages. In the second part of the paper an example of using document models for solving a management problem of real complexity is demonstrated.

    Full Text Available Despite the efforts for sustainability studies in building and infrastructure construction, the sustainability issues in industrial construction remain understudied. Further, few studies evaluate sustainability and benchmark sustainability issues in industrial construction from a management perspective. This study presents a phase-based benchmarking framework for evaluating sustainability practices use focusing on industrial facilities project. Based on the framework, this study quantifies and assesses sustainability practices use, and further sorts the results by project phase and major project characteristics, including project type, project nature, and project delivery method. The results show that sustainability practices were implemented higher in the construction and startup phases relative to other phases, with a very broad range. An assessment by project type and project nature showed significant differences in sustainability practices use, but no significant difference in practices use by project delivery method. This study contributes to providing a benchmarking method for sustainability practices in industrial facilities projects at the project phase level. This study also discusses and provides an application of phase-based benchmarking for sustainability in industrial construction.

    The aim of this paper is to investigate the use of different self-reported measures for assessing the human response to environmental vibration from the construction of an urban LRT (Light Rapid Transit) system. The human response to environmental stressors such as vibration and noise is often expressed in terms of exposure–response relationships that describe annoyance as a function of the magnitude of the vibration. These relationships are often the basis of noise and vibration policy and the setting of limit values. This paper examines measures other than annoyance by expressing exposure–response relationships for vibration in terms of self-reported concern about property damage and acceptability. The exposure–response relationships for concern about property damage and for acceptability are then compared with those for annoyance. It is shown that concern about property damage occurs at vibration levels well below those where there is any risk of damage. Earlier research indicated that concern for damage is an important moderator of the annoyance induced. Acceptability, on the other hand, might be influenced by both annoyance and concern, as well as by other considerations. It is concluded that exposure–response relationships expressing acceptability as a function of vibration exposure could usefully complement existing relationships for annoyance in future policy decisions regarding environmental vibration. The results presented in this paper are derived from data collected through a socio-vibration survey (N = 321) conducted for the construction of an urban LRT in the United Kingdom. - Highlights: • The human response to construction vibration is assessed in residential environments. • Exposure–response relationships are generated based on survey and semi-empirical vibration estimation. • Annoyance, concern and acceptability are compared as response measures. • Concern and acceptability are viable measures complementing annoyance.

    Operation of the modern heavy aircraft on the surrounding vast territory is associated with the appearance of high levels of sound pressure generated by the powerful engines, especially during takeoff and landing operations. Currently, the elimination or significant reduction of noise pollution on the environment technically does not yet have a radical solution and the possible reduction of the impact ofnoise pollution on the residents ofnearby settlements is achievedfor residents of building by the optimal location of the runway, changing in conditions for the takeoff and landing of aircrafts, the ordering of the regimen of the airport, the introduction of the package sufficiently effective anti-noise diverse - engineering, planning activities, in some cases, the creation ofprotective noise shield on the border of the residential area and the construction ofprotective awnings over the children’s and sports fields with fencing shields converted in the direction of the runway. An example of a positive decision, taking into account the complexity and variety of aspects of the problem, it is possible to consider the development of the project plan of the new microdistrict «Eletsky» in the Soviet district of the city of Lipetsk, falling under the impact of aircraft noise of plying aircrafts of the military airfield.

  11. Narrating practice: reflective accounts and the textual construction of reality.

    Science.gov (United States)

    Taylor, Carolyn

    2003-05-01

    Two approaches dominate current thinking in health and welfare: evidence-based practice and reflective practice. Whilst there is debate about the merits of evidence-based practice, reflective practice is generally accepted with critical debate as an important educational tool. Where critique does exist it tends to adopt a Foucauldian approach, focusing on the surveillance and self-regulatory aspects of reflective practice. This article acknowledges the critical purchase on the concept of reflective practice offered by Foucauldian approaches but argues that microsociological and discourse analytic approaches can further illuminate the subject and thus serve as a complement to them. The claims of proponents of reflective practice are explored, in opposition to the technical-rational approach of evidence-based practice. Reflective practice tends to adopt a naive or romantic realist position and fails to acknowledge the ways in which reflective accounts construct the world of practice. Microsociological approaches can help us to understand reflective accounts as examples of case-talk, constructed in a narrative form in the same way as case records and presentations.

  12. The role of production and teamwork practices in construction safety: a cognitive model and an empirical case study.

    In construction, the challenge for researchers and practitioners is to develop work systems (production processes and teams) that can achieve high productivity and high safety at the same time. However, construction accident causation models ignore the role of work practices and teamwork. This study investigates the mechanisms by which production and teamwork practices affect the likelihood of accidents. The paper synthesizes a new model for construction safety based on the cognitive perspective (Fuller's Task-Demand-Capability Interface model, 2005) and then presents an exploratory case study. The case study investigates and compares the work practices of two residential framing crews: a 'High Reliability Crew' (HRC)--that is, a crew with exceptional productivity and safety over several years, and an average performing crew from the same company. The model explains how the production and teamwork practices generate the work situations that workers face (the task demands) and affect the workers ability to cope (capabilities). The case study indicates that the work practices of the HRC directly influence the task demands and match them with the applied capabilities. These practices were guided by the 'principle' of avoiding errors and rework and included work planning and preparation, work distribution, managing the production pressures, and quality and behavior monitoring. The Task Demand-Capability model links construction research to a cognitive model of accident causation and provides a new way to conceptualize safety as an emergent property of the production practices and teamwork processes. The empirical evidence indicates that the crews' work practices and team processes strongly affect the task demands, the applied capabilities, and the match between demands and capabilities. The proposed model and the exploratory case study will guide further discovery of work practices and teamwork processes that can increase both productivity and safety in construction

    Full Text Available Bioretention is a method of storm water management that includes several processes following the natural hydrological cycle. Bioretention, or variations of it, include rain gardens and bioswales, infiltrates, filtrates, evapotranspirates, and help to store and manage storm water run-off. A bioretention cell retains water, removes pollutants, and provides water elements for urban green areas. Although bioretention is a promising method for multifunctional storm water management, its construction details should not be copied from other climatic areas. A direct application may dismiss local conditions, materials, and construction practices. This study aimed to adapt construction details for bioretention to Finnish local practices and conditions and to formulate bioretention constructions that balance water, soil, and vegetation. First, construction details were reviewed, then local adaptations were applied, and finally, the application and two variations of growing media in two construction depths were tested in a test field in Southern Finland. Sandy growing media allowed the efficient retention of water during the first year, but failed to provide vital growth. The use of topsoil and compost in the growing media improved growth, but held high electrical conductivity after infiltration. All the experimental cells in the test field showed activity during the melting periods, both during winter and spring. If bioretention plays a multifunctional role in urban design and engineered ecology, the design parameters should not only focus on storm water quantity, but also on quality management and vegetation growth.

    To present the nursing outcomes from the evaluation of developments in the care environment in residential settings for older people. The evaluation data reported here is derived from a larger national programme of work that focused on the development of person-centred practice in residential services for older people using an emancipatory practice development framework. A multi-method evaluation framework was utilised. Outcome data were collected at three time points between December 2007 and September 2009. The data reported here were collected using an instrument called the 'Person-Centred Nursing Index'. Heavy workload was the main cause of stress among nurses. Personal and professional satisfaction with the job was scored highest by the total sample of nurses. Nineteen factors were examined using the Person-Centred Nursing Index. Statistically significant changes were observed in 12 of these. In addition, there were statistically significant changes in nurses' perceptions of caring, indicating a shift from a dominant focus on 'technical' aspects of care, to one where 'intimate' aspects of care were more highly valued. The findings highlight the importance of the development of effective teamwork, workload management, time management and staff relationships in order to create a culture where there is a more democratic and inclusive approach to practice and space for the formation of person-centred relationships. © 2010 Blackwell Publishing Ltd.

    2014-02-01

    Full Text Available The main object of this study is the reconstruction, renovation and modernization of the housing built in the period 1975—1985. These buildings have low energy efficiency due to the poor thermal insulation properties of the walls. These apartments do not meet the necessary requirements for year round warmth and comfort.Reconstruction is more preferable, than new-build, because of the cost saving for the land acquisition. Reconstruction is generally 1.5 times cheaper than new-build with 25—40 % reduced cost on building materials and engineering infrastructure.Increasing the width of the apartment blocks from 12 to 15 m can save 9—10 % on the consumption of thermal energy for heating and reduce the m2 construction cost by 5.5—7.0 %. In—5-9 storey high-rise buildings the savings are 3—5 %.Therefore, the width of the apartment block should preferably be between 9—12 m but could be extended to 18 m. The depth of the apartments themselves will be 5.4 — 6.0 —7.2 or 9.0 m. During the reconstruction of 5-storey residential buildings (Building Type105 in a seismic zone, an increase in the width of the block and the lateral stiffness of the building is achieved by building a new reinforced concrete (RC frame on both sides of the building with a depth of between 2 and 6 m. This technique is especially effective in increasing the seismic resistance of the building. Self-supporting walls of cellular concrete blocks (density 600 kg/m3 and a thickness of 300 mm are constructed on the outside of the frame, taking care to avoid cold bridges.Model studies have shown that in the conditions of hot-arid climate the thickness of the air gap in a ventilated facade does not significantly change the cooling-energy consumption of the building, and heating consumption is significantly increased. The building's energy consumption is most influenced by the volume of the air in the air gap. By increasing the ventilation rate in the air gap, the energy

    1985-02-01

    The following report examines the technical and economic viability of residential greenhouse additions in Whitehorse, Yukon. The greenhouse was constructed using the south facing wall of an existing residence as a common wall. Total construction costs were $18,000, including labour. Annual fuel demand for the residence has been reduced by about 10 per cent for an annual saving of $425. In addition, produce to the value of $1,000 is grown annually in the greenhouse for domestic consumption and commercial resale. Typically the greenhouse operates for nine months each year. There is a net thermal loss during the months of November, December and January as a result of the large area of glazing. As well as supplementing the heating supply solar greenhouses can provide additional cash crops which can be used to offset the cost of construction. Humidity problems are minimal and can be dealt with by exhausting high humidity air. One system which has been considered for the greenhouse is to use a standard residential heat pump to remove excess moisture and to pump heat into the house. This would have a secondary benefit of excluding the need to circulate greenhouse air through the house. Thus any allergenic reactions to the greenhouse air would be prevented. 8 refs., 3 figs, 2 tabs.

    Highlights: ► A significant reduction of construction waste was achieved at the first 3 years of CWDCS implementation. ► However, the reduction cannot be sustained. ► Implementation of the CWDCS has generated positive effects in waste reduction by all main trades. - Abstract: Waste management in the building industry in Hong Kong has become an important environmental issue. Particularly, an increasing amount of construction and demolition (C and D) waste is being disposed at landfill sites. In order to reduce waste generation and encourage reuse and recycling, the Hong Kong Government has implemented the Construction Waste Disposal Charging Scheme (CWDCS) to levy charges on C and D waste disposal to landfills. In order to provide information on the changes in reducing waste generation practice among construction participants in various work trades, a study was conducted after 3 years of implementation of the CWDCS via a structured questionnaire survey in the building industry in Hong Kong. The study result has revealed changes with work flows of the major trades as well as differentiating the levels of waste reduced. Three building projects in the public and private sectors were selected as case studies to demonstrate the changes in work flows and the reduction of waste achieved. The research findings reveal that a significant reduction of construction waste was achieved at the first 3 years (2006–2008) of CWDCS implementation. However, the reduction cannot be sustained. The major trades have been influenced to a certain extent by the implementation of the CWDCS. Slight improvement in waste management practices was observed, but reduction of construction waste in the wet-finishing and dry-finishing trades has undergone little improvement. Implementation of the CWDCS has not yet motivated subcontractors to change their methods of construction so as to reduce C and D waste.

    2014-07-01

    Full Text Available Material management is an important issue as seen in construction waste management. Best practice of material management is accompanied by various benefits which are acknowledged by several studies. The site layout has particular effects on both materials and their waste through effective waste management practice. Ignoring the benefits of material management could result in a daily reduction in productivity of up to 40% by material wastage. Thus, the benefits of effective material management must be well comprehended for the sake of waste minimization. Another convincing fact about waste is that poor site management accounts for the largest factor of waste generation. Hence the site condition is very crucial in developing effective material management. Factors contributing to the efficiency of material management process are effective logistical management and supply chain management. The logistics system must be performing as schedule so that materials are wisely managed on-site without encountering presence of excessive materials. As materials management is closely related to logistics in construction projects, there will be delay in construction projects when materials are not delivered to site as scheduled. The management must be effective in terms of delivery, off-loading, storage, handling, on-site transportation and on-site utilization of materials.

    Evans, Rhiannon E

    2018-05-01

    Research on clinicians' interpretations of self-harming practices has shown that they can often be negative. To date there has been limited consideration of other professionals' narratives, notably those working in social care. This article presents focus group and interview data generated with foster carers ( n = 15) and residential carers ( n = 15) to explore the symbolic meanings ascribed to self-harm among the children and young people they care for. Three repertoires of interpretation are presented: survival, which conceives self-harm as a mechanism for redefining the identity of "looked-after"; signaling, which understands self-harm as a communicative tool for the expression of emotion; and security, which sees self-harming practices as testing the authenticity and safety of the caring relationship. Through their focus on sociocultural narratives, carers position themselves as experts on self-harm due to their intimacy with young people's social worlds. This construction potentially creates distance from health professionals, which is problematic given the current privileging of interprofessional working.

    Full Text Available The use of robotic systems in performing construction tasks has great potential; however the development of such systems remains problematic. This is due to the lack of a suitable feasibility analysis that can help the decision makers to justify the use of robots and problems in the development process of the system itself. The multidisciplinary and complex nature of construction robotic systems requires a robust development framework for such systems. An augmented framework for the development of construction robots is explained in detail and practically applied to the Star lifter robotic system which is mainly designed to carry heavy tools for construction tasks. The framework consists of two models; the feasibility analysis model and the development process model. The feasibility analysis principles, methodology and tools are explained and discussed in detail. Systems Engineering model is used in the development of the system which allows complete analysis of the system hardware and software components. The purpose of the current project is to develop a general purpose robot that can be employed to perform different jobs to justify its use economically. The presented tools and processes can be utilised in the development of any similar systems.

    The housing estates in Bratislava saturated the housing needs of a large number of inhabitants who come after World War II to the city. Design of public spaces often did not have priority in the process of designing. The solutions for mentioned exterior spaces had been planned after blocks of flat realization, but many of them are not realized to this day. The article analyzes the example of the unrealized public spaces in existing housing estates Devinska Nova Ves and Petržalka (city districts of Bratislava) and offer practical solutions in relation to residencialization method. Residencialization of missing public places is an effective method of adding identities to settlements. It improves the quality of residential environment and public spaces. The main aim is to create better conditions for social activities in public areas, which are missing on the present. The research will be focused on the examination of the urban, cultural and construction potential of the existing residential enviroment in Bratislava. The main aim of residentialization is not only to enhance the quality of spatial and building structures in the selected residential area and maintain long-term sustainability in the pertinent programme area, but mainly to improve the quality of living for the residents. The outputs of the project are proposals and practical procedures developed with regard to planning documents for local municipal authorities and regional organizations. The solutions will have a positive impact on the enhancement of the quality of public spaces, attractive social activities and of a conceptual link - residentialization.

    Construction waste management (CWM) is the practice of minimizing and diverting construction waste, demolition debris, and land-clearing debris from disposal and redirecting recyclable resources back into the construction process. Best practice model means best choice from the collection of other practices that was built for purpose of construction waste management. The practice model can help the contractors in minimizing waste before the construction activities will be started. The importance of minimizing wastage will have direct impact on time, cost and quality of a construction project. This paper is focusing on the preliminary study to determine the factors of waste generation in the construction sites and identify the effectiveness of existing construction waste management practice conducted in Malaysia. The paper will also include the preliminary works of planned research location, data collection method, and analysis to be done by using the Analytical Hierarchy Process (AHP) to help in developing suitable waste management best practice model that can be used in the country.

    2017-11-01

    The effectiveness of the implementation of construction waste reduction through 3R reflects the sustainability in construction waste management. Weak implementation of construction waste reduction through 3R among contractors will lead to unsustainable construction waste management. Increase in construction waste on landfills is critical especially on islands where land is very limited for solid waste disposal. This aim of this paper is to investigate current practice of construction waste reduction through 3R practice among contractors in Penang, Malaysia. The findings reported herein is based on feedbacks from 143 construction contractors of grade CIDB G7, G6 and G5 in Penang and experts from Penang Local Authority, CIDB in Penang and its Headquarters, National Solid Waste Management Department, and Headquarters of Solid Waste and Public Cleansing Management Corporation. Interviews and questionnaire surveys have been found that 3R practice is not mandatory in construction waste management in Penang. Only 39.8% construction contractors practiced 3R in managing their waste. Therefore, 3R practices should be emphasized in construction industry. Reducing wastes through 3R practices in construction industry is a way forward towards sustainable construction waste management especially in expanding the lifetime of landfill.

    The aims of this study were to evaluate establishing and operating a web-based community of practice (CoP) to lead falls prevention in a residential aged care (RAC) setting. A mixed methods evaluation was conducted in two phases using a survey and transcripts from interactive electronic sources. Nurses and allied health staff (n = 20) with an interest in falls prevention representing 13 sites of an RAC organization participated. In Phase 1, the CoP was developed, and the establishment of its structure and composition was evaluated using determinants of success reported in the literature.

    This study examined the relevance and fit of the PARiHS framework (Promoting Action on Research Implementation in Health Services) as an explanatory model for practice change in residential aged care. Translation of research knowledge into routine practice is a complex matter in health and social care environments. Examination of the environment may identify factors likely to support and hinder practice change, inform strategy development, predict and explain successful uptake of new ways of working. Frameworks to enable this have been described but none has been tested in residential aged care. This paper reports preliminary qualitative analyses from the Encouraging Best Practice in Residential Aged Care Nutrition and Hydration project conducted in New South Wales in 2007-2009. We examined congruence with the PARiHS framework of factors staff described as influential for practice change during 29 digitally recorded and transcribed staff interviews and meetings at three facilities. Unique features of the setting were flagged, with facilities simultaneously filling the roles of residents' home, staff's workplace and businesses. Participants discussed many of the same characteristics identified by the PARiHS framework, but in addition temporal dimensions of practice change were flagged. Overall factors described by staff as important for practice change in aged care settings showed good fit with those of the PARiHS framework. This framework can be recommended for use in this setting. Widespread adoption will enable cross-project and international synthesis of findings, a major step towards building a cumulative science of knowledge translation and practice change. © 2011 The Authors.

    Full Text Available The empirical analysis of capital budgeting or investment appraisal is a topic that has been widely studied in developed countries, such as the United States, the United Kingdom, and Canada. The documentation of these practices in emerging countries is scarce. This paper provides some information about current capital budgeting techniques through an empirical study of practices in a group of Colombian companies in the construction industry. In the companies surveyed it was found that 86% of professionals use the most recommended methods in the literature, such as the Internal Rate of Return (IRR and Net Present Value (NPV, with a preference for the IRR (50% always use it over the NPV (36% always use it. It was also found that 95% lack knowledge of more sophisticated methods, such as Real Options (OR. Most of the respondents subjectively determine the discount rate that is used for evaluation, indicating the lack of any theoretical justification to determine an appropriate rate.

    2015-06-01

    Total concentrations of heavy metals (Cu, Zn, Pb, Cr, Cd, and Ni) were measured among 63 samples of construction and demolition (C&D) wastes collected from chemical, metallurgical and light industries, and residential and recycled aggregates within China for risk assessment. The heavy metal contamination was primarily concentrated in the chemical and metallurgical industries, especially in the electroplating factory and zinc smelting plant. High concentrations of Cd were found in light industry samples, while the residential and recycled aggregate samples were severely polluted by Zn. Six most polluted samples were selected for deep research. Mineralogical analysis by X-ray fluorescence (XRF) spectrometry and X-ray diffraction (XRD), combined with element speciation through European Community Bureau of Reference (BCR) sequential extraction, revealed that a relatively slight corrosion happened in the four samples from electroplating plants but high transfer ability for large quantities of Zn and Cu. Lead arsenate existed in the acid extractable fraction in CI7-8 and potassium chromium oxide existed in the mobility fraction. High concentration of Cr could be in amorphous forms existing in CI9. The high content of sodium in the two samples from zinc smelter plants suggested severe deposition and erosion on the workshop floor. Large quantities of Cu existed as copper halide and most of the Zn appeared to be zinc, zinc oxide, barium zinc oxide, and zincite. From the results of the risk assessment code (RAC), the samples from the electroplating factory posed a very high risk of Zn, Cu, and Cr, a high risk of Ni, a middle risk of Pb, and a low risk of Cd. The samples from the zinc smelting plant presented a high risk of Zn, a middle risk of Cu, and a low risk of Pb, Cr, Cd, and Ni.

    2015-01-01

    While researchers are increasingly re-conceptualizing international migration, far less attention has been devoted to re-thinking short-distance residential mobility and immobility. In this paper we harness the life course approach to propose a new conceptual framework for residential mobility research. We contend that residential mobility and immobility should be re-conceptualized as relational practices that link lives through time and space while connecting people to structural conditions. Re-thinking and re-assessing residential mobility by exploiting new developments in longitudinal analysis will allow geographers to understand, critique and address pressing societal challenges.

    Chipo Mellania Maseko

    2017-12-01

    Full Text Available The construction of projects is mostly symbolised by the extraordinary levels of unethical practices and this has ruined the image of the industry. The delivery of good quality infrastructure projects in some emerging economies is continuously, disrupted because of unethical practices. This paper was, initiated to identify the most dominant unethical practices in the construction of projects, using most recent and comprehensive literature ranging from 2011 to 2017. Twenty unethical practices in the construction of projects were, identified. From this, the study observed that the most dominant unethical practices are corruption, bribery and collusive tendering. The least unethical practices revealed by this study are the lack of safety, overstatement of capacity and falsification of experience. Findings indicate that in order to redesign the future landscape of the industry, there is need to educate the workforce on the effects of unethical practices as well as the need to implement stronger policies. Based on these findings, further empirical studies are necessary. This article also presents recent challenges and trends of unethical behaviour that needs acknowledgement in order to assist the construction industry. In conclusion, this study proposes twelve possible solutions that could assist the construction community in the reduction of unethical practices

    2017-12-01

    Full Text Available Despite the increasing investment in sustainable development over the past decade, a systematic review of sustainable construction project financing is lacking. The objectives of this paper are to conduct a systematic review to examine the policies, practices, and research efforts in the area of sustainable construction project financing, and to explore the potential opportunities for the future research. To achieve these goals, this paper first reviewed the sustainable construction project financing practices implemented by four representative developed economies including the United Kingdom, the United States, Singapore, and Australia. Then, this paper reviewed the efforts and initiatives launched by three international organizations including the United Nations, the Organization for Economic Co-operation and Development, and International Finance Corporation. After that, this paper reviewed the research efforts of sustainable construction project financing published in peer-review journals and books. This paper identified four major research themes within this area, which are the review of financial stakeholders and market of sustainable construction, benefits and barriers to sustainable construction project financing, financial vehicles for sustainable construction projects, innovative models and mechanisms for sustainable construction project financing. Additionally, this paper revealed five directions for the future research of sustainable construction project financing, which are the identification of financial issues in sustainable construction projects, the investigation of financial vehicles for sustainable construction projects in terms of their strengths, limitations, and performances, the examination of critical drivers for implementing sustainable construction project financing, the development of a knowledge-based decision support system for implementing sustainable construction financing, and the development of best practices for

    Gillen, Matt

    2010-06-01

    The U.S. National Institute for Occupational Safety and Health (NIOSH) conducts research to improve and protect the health and safety of workers. This paper describes the experience of the NIOSH Construction Program with two recent program planning initiatives intended to improve the program: (a) an independent external review of work over the past decade and (b) the development of strategic goals organized into a "National Construction Agenda" to guide a decade of future work. These goals, developed with input from construction industry stakeholders and researchers, are a part of the NIOSH National Occupational Research Agenda (NORA) initiative. The NORA goals are intended to provide an ambitious set of goals for all construction stakeholders to work together on. Both efforts relate to insuring the relevance and impact of research, reflecting an emerging policy perspective that research programs should be judged not just by the quality and quantity of science produced, but by the industry impact and tangible benefit resulting from the research. This paper describes how views on research planning have evolved to incorporate lessons learned about how research leads to improved safety and health for workers. It also describes the process used to develop the goals and the resulting strategic and intermediate goals that comprise the National Construction Agenda. (c) 2010 Elsevier Ltd. All rights reserved.

    2012-11-01

    Full Text Available Recent world events in the international relations arena and the subsequent knock-on affect on the insurance industry, have sent shock-waves through Australia’s business community,elevating crisis management to the top of the managerial agenda. This paperpresents the findings of exploratory research, which investigated the crisis managementpractices of construction companies. Using a diagnostic model of crisis preparednesswhich has been developed and tested across a broad range of industries, it concludes thatif the sample surveyed is typical, then crisis planning is rudimentary and undertaken in aninsular, informal, fragmented fashion, supported by few resources and little strategicguidance. Consequently, many construction companies will have an inadequate understandingof their crisis exposure, of how to cope with crises when they happen and of howto learn and recover from their aftermath.

    2016-01-01

    Full Text Available The demand of high-rise projects continues to grow due to the reducing of usable land area in Klang Valley, Malaysia. The rapidly development of high-rise projects has leaded to the rise of fatalities and accidents. An accident that happened in a construction site can cause serious physical injury. The accidents such as people falling from height and struck by falling object were the most frequent accidents happened in Malaysian construction industry. The continuous growth of high-rise buildings indicates that there is a need of an effective safety and health management. Hence, this research aims to identify the causes of accidents and the ways to prevent accidents that occur at high-rise building construction site. Qualitative method was employed in this research. Interview surveying with safety officers who are involved in highrise building project in Kuala Lumpur were conducted in this research. Accidents were caused by man-made factors, environment factors or machinery factors. The accidents prevention methods were provide sufficient Personal Protective Equipment (PPE, have a good housekeeping, execute safety inspection, provide safety training and execute accidents investigation. In the meanwhile, interviewees have suggested the new prevention methods that were develop a proper site layout planning and de-merit and merit system among sub-contractors, suppliers and even employees regarding safety at workplace matters. This research helps in explaining the causes of accidents and identifying area where prevention action should be implemented, so that workers and top management will increase awareness in preventing site accidents.

    2017-12-01

    Full Text Available This article categorizes and analyzes the places where contact improvisation (CI is danced in Spain between the years 2010 and 2015. Starting from the idea that space is not only constructed, but in turn defines bodies and ideologies in concurrence with different practices, we identify some directions, confluences or tensions that are established between the corporal, artistic, educational and therapeutics techniques to which the CI dance is rooted. Both, content analysis and fieldwork indicate an expansion in the number and category of places for the practice of CI in Spain; we highlight, in this regard, the increase of residential rural spaces along with a wide range of urban spaces of dance, interdisciplinary and multipurpose. These trends in the use of various spaces for CI inform about the definition and about the development of a broad spectrum of choreographic tendencies and social movements. CI shares aesthetic, ethical or educational principles, including collective management.

  15. Supporting Photovoltaics in Market-Rate Residential NewConstruction: A Summary of Programmatic Experience to Date and LessonsLearned

    Energy Technology Data Exchange (ETDEWEB)

    Barbose, Galen; Wiser, Ryan; Bolinger, Mark

    2006-02-10

    As a market segment for solar photovoltaic (PV) adoption, new homes have a number of attractive attributes. Homebuyers can easily roll the cost of the PV system into their tax-deductible home mortgage and, with rebates and other financial incentives, potentially achieve an immediate net-positive cash flow from the investment. New homes are amenable to building-integrated photovoltaics (BIPV), which are less susceptible to aesthetic concerns than traditional, rack-mounted systems. The performance of PV systems can be optimized on new homes by taking roof orientation and shading into account when designing the home. Perhaps most importantly, subdivisions with PV systems installed on a large number of homes offer potential cost savings from volume purchases of modules and inverters and from scale economies in system design and installation. Finally, the ability of builders to install PV as a standard feature on multiple homes in new subdivisions offers an opportunity to circumvent the high transaction costs and information-related market barriers typically confronted when each individual homeowner must make a decision about installing PV. Builders may benefit in several ways from incorporating PV into new homes. Builders may gain greater market differentiation, enhanced media exposure, and less community or political opposition to development projects. Additionally, if homebuyers place a high value on PV, builders may be able to earn additional profits, just as they would on granite countertops or other high-value home features. Although the impact of PV on the original sale price of new homes has not yet been rigorously examined, some limited empirical evidence does suggest that PV and energy efficient features may have a positive effect on resale value. Along with its unique advantages, residential new construction also faces unique barriers to PV adoption. Most fundamentally, perhaps, is the general aversion to technology risk within the building industry

  16. A Practical Approach to Constructing a Knowledge Graph for Cybersecurity

    2018-02-01

    Full Text Available Cyberattack forms are complex and varied, and the detection and prediction of dynamic types of attack are always challenging tasks. Research on knowledge graphs is becoming increasingly mature in many fields. At present, it is very significant that certain scholars have combined the concept of the knowledge graph with cybersecurity in order to construct a cybersecurity knowledge base. This paper presents a cybersecurity knowledge base and deduction rules based on a quintuple model. Using machine learning, we extract entities and build ontology to obtain a cybersecurity knowledge base. New rules are then deduced by calculating formulas and using the path-ranking algorithm. The Stanford named entity recognizer (NER is also used to train an extractor to extract useful information. Experimental results show that the Stanford NER provides many features and the useGazettes parameter may be used to train a recognizer in the cybersecurity domain in preparation for future work.

    are discussed in this chapter. Characterizing residential waste is faced with the problem that many residences already divert some waste away from the official collection systems, for example performing home composting of vegetable waste and garden waste, having their bundled newspaper picked up by the scouts...... twice a year or bringing their used furniture to the flea markets organized by charity clubs. Thus, much of the data available on residential waste represents collected waste and not necessarily all generated waste. The latter can only be characterized by careful studies directly at the source......, but such studies are very expensive if fair representation of both spatial and temporal variations should be obtained. In addition, onsite studies may affect the waste generation in the residence because of the increased focus on the issue. Residential waste is defined in different ways in different countries...

    A cross-sectional survey was conducted with the objective to explore a community's knowledge and practices towards prevention of Influenza A (H1N1) in three residential areas in Tampin. Respondents were randomly selected from a list of residences and interviewed face-to-face using a structured questionnaire. A total of 221 respondents (80.9%) were involved with the majority (64.7%) comprising female and who had attained secondary level of education (86.0%). The main source of information was from television/radio. The total score for knowledge questions was 15 and practice questions were 25. A total of 60.2% attained "adequate knowledge" and 52.0% "good practice". Mean (SD) for knowledge score was 11.6 (2.3) and practice was 18.1 (4.1). Ethnicity, education, income and practice score were identified as predictors for knowledge score. Income and knowledge scores were predictors for practice score. There was positive correlation between knowledge and practice scores.

    Drawing upon post doctoral reflections of a shared methodology, the authors explore the use of bricolage as a way of better understanding the inter-related connections between theory, nursing practice and the felt experiences of service users. The origins of bricolage can be traced back to the work of Levi-Strauss, and Denzin and Lincoln's contribution to qualitative methodologies. Bricolage is a multifaceted approach to the research process. Differing epistemological positions and mixed methods of data collection are utilised to bring a richer understanding of human beings and the complexities of their lived experiences. For the bricoleur the object of inquiry, cannot be separated from its context, that is the language used to describe it, its historical situatedness and the social and cultural interpretations of its meaning as an entity in the world. The paper discusses the importance of being able to move beyond the notion of the research method being merely a procedure, to one that respects the complexities of the lived world.

    Full Text Available The study investigates the essential skill requirements for construction managers in Nigeria. The objective is to determine the most important skill requirements for construction managers. A structured questionnaire was administered to construction professionals who worked recently with construction managers in their recently completed projects. Snowballing sampling technique was used to select seventy (70 respondents, however only forty (40 responses were used for the data analysis. The results indicate that essential skills required by the construction managers for their jobs include: procedural-industrial skills, quality assurance/management, listening skills, knowledge of codes and regulations, sustainable skills and ability to learn skills. These skills are important for the construction manager to practice effectively in Nigeria and other developing countries. These findings have seven practical implications to professional bodies, Universities and other trainers of construction managers, whose present curricula may be deficient in knowledge areas in industry (business, managerial, personal and technical. These institutions may need to re-orientate and improve the curricula for newly trained construction managers to cope with current skill requirements. On the other hand, recruiting agencies should ensure that job applicants with the right hard and soft skills are engaged as construction managers. Consequently efficient and effective management of future construction projects in Nigeria and other developing countries can be ensured.

    2016-09-01

    Full Text Available This research investigates management practices that have the potential to enhance productivity in building projects by focusing on construction methods. In phase 1 of the study, face-to-face interviews with nineteen experts were conducted to identify the best management practices for construction methods. The qualitative data analysis reached saturation and resulted in a list of best practices for construction methods that are relevant to the local industry. The second phase used an industry-wide survey to prioritize the best practices. Accordingly, project start-up plan, traffic control plan, machinery positioning strategy, project completion plan, and dynamic site layout plan were shown to be the top five best practices for construction methods. The study also revealed that high levels of implementation of best practices are associated with low levels of project delays. The use of best practices also varied according to the project costs. There were no discernible differences between the top five best practices. The authors suggest that they should be implemented jointly to improve productivity in building projects. Contractors could use the logistic regression model developed, to predict the probability of exceeding a baseline productivity factor and, on that basis, implement corrective actions to achieve the desired level of productivity.

    Full Text Available This study examines the spatial polarization that characterizes the dwellings in the African leading megacity of Lagos. Data were collected through an extensive housing survey carried out on 1,485 household residences in 56 wards within 12 administrative units in Lagos megacity. The spatial dimension of residential density in the city generates three unique residential patterns which are low residential density (LRD, medium residential density (MRD, and high residential density (HRD areas. Descriptive and multivariate inferential statistics were used to render explanations for the spatial variations in the residential quality variables in the study area. Findings indicated that a clear difference exists in the residential quality within the three residential density areas of Lagos. High correlations exist among the residential quality indicators and housing type. The principal component analysis shows that residential polarizations that occur in the LRD, MRD, and HRD are based on the location, dwelling facility, interior and exterior quality, neighborhood integrity, social bond, barrier to entry, and security. The practical implications of residential polarizations along the residential density areas are explicitly expressed.

    Implementation of Building Information Modelling (BIM) was expected to bring improvement in current practices of Malaysian construction industry. In the design phase, there is a lack of a ready pool of skilled workers who are able to develop BIM strategic plan and effectively utilise it. These create boundaries for BIM nature in Malaysian construction industry specifically in the design phase to achieve its best practices. Therefore, the objectives of this research are to investigate the current practices of BIM implementation in the design phase as well as the best practices factors of BIM implementation in the design phase. The qualitative research approach is carried out through semi-structured interviews with the designers of different organisations which adopt BIM in the design phase. Data collection is analysed by executing content analysis method. From the findings, the best practices factors of BIM implementation in design phase such as the incentive for BIM training, formal approach to monitoring automated Level of Detailing (LOD), run a virtual meeting and improve Industry Foundation Class (IFC). Thus, best practices factors which lead to practices improvements in the design phase of project development which subsequently improves the implementation of BIM in the design phase of Malaysian construction industry.

    2015-01-01

    Full Text Available Previous research has indicated that women are significantly under-represented in the Nigerian construction industry and that female undergraduates face barriers that deter them from engaging in construction practice. This research examined the barriers faced by female undergraduates in the construction disciplines at Nigerian Universities. The research adopted the use of a questionnaire and semi-structured interviews. A total of 360 questionnaires were distributed, and 259 (71.94% were returned and used in the analysis. The semi-structured interviews were conducted with 50 female students and 16 women across the professions of Architecture, Building, Civil Engineering and Quantity Surveying. The results revealed that the undergraduates perceived the construction practice to be synonymous with site activities and that family responsibility posed the greatest barrier to their participation. The strategies identified by the women in practice included active participation in the activity of professional bodies and seeking a mentor. It was concluded that female graduates can be attracted to the industry, but efforts need to be put in place to successfully implement the strategies identified by the professional women. A framework that addresses gender issues in attracting and retaining graduates in the construction practice was developed to help women plan their career in the industry.

    2017-11-01

    Malaysia construction industry has been growing continuously with double-digit growth for the past two decades. There are many issues surrounded the industry such as delay in delivery, cost overrun, quality and safety. In bumiputera contractor’s context, the literature review found that 32 issues were encountered in the construction project. These issues can be handled properly with the application of risk management. According to previous researchers, application of risk management in Malaysia construction industry is at the low level where it is implemented in traditional ways that are brainstorming and checklist. These were due to lack of knowledge, the high cost of hiring experts and avoiding extra cost. Besides that, this study also intentions to analyse the risk categories in the construction industry as well as identify risk management process to resolve the construction issues. Hence, this paper presents issues engulfed by Bumiputera contractors which can partly be resolved by applying risk management practice in carrying out the construction activity. This may inspire the contractors to apply the risk management practice in ensuring the success of their construction project.

    As a result of increasing recognition of effective site management as the strategic approach for achieving the required performance in construction projects, this study seeks to identify the key site management practices that are requisite for construction waste minimization. A mixed methods approach, involving field study and survey research were used as means of data collection. After confirmation of construct validity and reliability of scale, data analysis was carried out through a combination of Kruskal-Wallis test, descriptive statistics and exploratory factor analysis. The study suggests that site management functions could significantly reduce waste generation through strict adherence to project drawings, and by ensuring fewer or no design changes during construction process. Provision of waste skips for specific materials and maximisation of on-site reuse of materials are also found to be among the key factors for engendering waste minimization. The result of factor analysis suggests four factors underlying on-site waste management practices with 96.093% of total variance. These measures include contractual provisions for waste minimization, waste segregation, maximisation of materials reuse and effective logistic management. Strategies through which each of the underlying measures could be achieved are further discussed in the paper. Findings of this study would assist construction site managers and other site operatives in reducing waste generated by construction activities. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Although research shows that "food parenting practices" can impact children's diet and eating habits, current understanding of the impact of specific practices has been limited by inconsistencies in terminology and definitions. This article represents a critical appraisal of food parenting practices, including clear terminology and definitions, by a working group of content experts. The result of this effort was the development of a content map for future research that presents 3 overarching, higher-order food parenting constructs--coercive control, structure, and autonomy support--as well as specific practice subconstructs. Coercive control includes restriction, pressure to eat, threats and bribes, and using food to control negative emotions. Structure includes rules and limits, limited/guided choices, monitoring, meal- and snacktime routines, modeling, food availability and accessibility, food preparation, and unstructured practices. Autonomy support includes nutrition education, child involvement, encouragement, praise, reasoning, and negotiation. Literature on each construct is reviewed, and directions for future research are offered. Clear terminology and definitions should facilitate cross-study comparisons and minimize conflicting findings resulting from previous discrepancies in construct operationalization. © The Author(s) 2016.

    2017-12-01

    Full Text Available Low- and middle-income countries lag behind in research that is related to the construction industry and the waste problems that the sector is facing. Literature shows that waste reduction and recycling have received a continuous interest from researchers, but mainly from developed countries. Few reports from low- and middle-income countries are concerned about the reuse of masonry, concrete, and mortar in clay based building ceramics or recycling construction waste, but mostly in relation to concrete aggregates. Furthermore, few authors have described the major barriers and motivations for construction waste reduction. The objective of this paper is to report the findings on a research performed in Costa Rica with the objective to determine the barriers and motivations that the construction sector is facing to improve the management of the construction materials. The study is based on data collected in two phases. During the first phase, a survey was sent via e-mail to 419 main contractors registered at the School Federation of Engineers and Architects (CFIA. The second phase consisted of a focus group discussion with 49 professionals from the construction industry to analyse and validate the findings from the survey. Descriptive statistic methods helped to draw the conclusions. The result of the research is a comprehensive list of observed barriers and motivations for waste reduction practices in the construction sector. These are not only applicable to Costa Rica, but can be used as a guide for similar studies in other low- and middle-income countries.

    Mohd Nawi Mohd Nasrun

    2014-01-01

    Full Text Available Problems associated with fragmentation in the traditional construction process, such as isolation of professionals, lack of co-ordination between design and construction, and the sequential manner of its processes, has impacted on construction performance leading to a lack of integration, wastage, low productivity and efficiency. Integrated team practice is perceived as paramount. Unfortunately, there has a limitation of study focus on the dimension of fully integrated team especially for Malaysian Industrialised Building System (IBS projects. Accordingly, this research paper explores and identifies the dimension of fully integrated team from the traditional approach and conduct a validation process for implementing it in Malaysian IBS projects. The research presented uses interviews case study to obtain qualitative data. It was found that the dimension of fully integrated team from the traditional construction process could apply to the Malaysian IBS projects. Suggestions on how an integrated team practice in IBS design and construction process in order to minimise the fragmentation gaps will be concluded.

  7. Constructing an Ethical Training for Advanced Nursing Practice: An Interactionist and Competency-Based Approach.

    Science.gov (United States)

    Pariseau-Legault, Pierre; Lallier, Melisa

    2016-07-01

    Advanced practice nurses are working in a highly interdisciplinary and political context. Such situations can influence the deliberative and ethical decision-making processes in which they are also involved. This can subsequently compromise their abilities to protect their moral integrity, to find innovative and nondualistic solutions to complex ethical problems, and to collaborate with other health professionals. The authors constructed a training program inspired by discourse and narrative ethics. The objective pursued was to develop advanced practice nurses' moral integrity, highlight the ethical component of their clinical judgement, and foster the development of their deliberative competencies. The pedagogical process proposed exposes how an ethical curriculum adapted to the context in which advanced practice nurses evolve can address power relationships inherent in ethical decision making. The authors suggest that this pedagogical approach has the potential to optimize the consolidation of ethical, reflective, and deliberative competencies among advanced practice nurses.

    Tam, Vivian W Y; Kotrayothar, Duangthidar; Loo, Yew-Chaye

    2009-03-01

    Waste generated from construction and building demolition work constitutes about 68% of all solid waste generated each year in South East Queensland. Consequently, it has created a serious waste management problem. The State Governments of Victoria and New South Wales have been encouraging the use of recycled materials from construction and related waste; they have also promulgated specifications for their use. In Queensland, however, similar regulations are not anticipated in the near future, which explains the lack of funded research conducted in this important arena. This paper presents an evaluation of the prevailing waste recycling practices in Queensland. Nine sites were visited, including two construction sites, three demolition sites, three recycling plants and one landfill in South East Queensland. The difficulties encountered by the recycling programme operators and their associates at these sites are described and the benefits of recycling construction materials are presented. One of the major barriers is that the local councils disallow the use of recycled materials in new construction work. To help rectify these impediments to recycling, recommendations are given to increase the use of recycled construction waste in South East Queensland.

    2008-05-01

    The aim of this study was to examine the impact of nurses' perceived professional practice environment on their quality of nursing conflict management approaches and ultimately their perceptions of unit effectiveness from the perspective of Deutsch's theory of constructive conflict management. Rising reports of hostility and conflict among Canadian nurses are a concern to nurses' health and the viability of effective patient care delivery. However, research on the situational factors that influence nurses' ability to apply effective conflict resolution skills that lead to positive results in practice is limited. A nonexperimental, predictive design was used in a sample of 678 registered nurses working in community hospitals within a large metropolitan area in Ontario. The results supported a modified version of the hypothesized model [chi2(1) = 16.25, Goodness of Fit = 0.99, Comparative Fit Index = 0.98, Root-Mean-Square Error of Approximation = 0.15] linking professional practice environment and core self-evaluation to nurses' conflict management and, ultimately, unit effectiveness. Professional practice environment, conflict management, and core-self evaluation explained approximately 46.6% of the variance in unit effectiveness. Positive professional practice environments and high core self-evaluations predicted nurses' constructive conflict management and, in turn, greater unit effectiveness.

    A Retrofit Best Practices Guide was developed to encourage homeowners to consider energy conservation issues whenever they modify their siding or windows. In support of this guide, an experimental program was implemented to measure the performance of a number of possible wall siding and window retrofit configurations. Both thermal and air-leakage measurements were made for a 2.4 x 2.4 m (8 x 8 ft) wall section with and without a 0.9 x 1.2 m (3 x 4 ft) window. The windows tested were previously well-characterized at a dedicated window test facility. A computer model was also used to provide information for the Best Practices Guide. The experimental data for walls and windows were used in conjunction with this model to estimate the total annual energy savings for several typical houses in a number of different locations.

  12. A revisit on the current practice of dispute resolution and ADR in the Malaysian construction industry

    Directory of Open Access Journals (Sweden)

    Mohd Suhaimi Mohd Danuri

    2012-06-01

    Full Text Available The current dispute resolution procedures available in the Malaysian construction industry are mainly litigation and arbitration. In addition, the alternative dispute resolutions (ADR, namely mediation and adjudication, have also been introduced as the other methods for resolving disputes. The objective of this study is to examine the current practice of dispute resolution and ADR available in the Malaysian construction industry. The aim of this paper is two-fold: to report the current practice of dispute resolution and ADR, and identify the attributes of successful implementation of both mechanisms based on the perceptions of the Malaysian construction industry players. From the jurisprudence point of view, this study looks into the law as it is, in relation to the current practice of dispute resolution and ADR, by showing how those findings can be used to explain why improvement is needed to promote a successful and well received dispute resolution and ADR, and what lessons can be learnt, towards the formulation of a more viable methods for the Malaysian construction industry. NVivo software has been used to manage and organise the complete interview transcripts and facilitate the data analysis process for this study. Literature review reveals a continuous development of dispute resolution and ADR in the Malaysian construction industry, while, globally the industry has not only embraced ADR but also spearheaded the development of innovative forms of dispute avoidance mechanism. The findings of interviews show that locally, apart from litigation, the common types of ADR are arbitration, mediation and ad hoc mechanism. The findings also lead to the discovery of the following attributes: faster, less procedural, cost effective and enforceable; regulation and government's support; professionalism and ethic; training; and facility, that may promote a successful implementation of dispute resolution and ADR in Malaysia.

    that play a role in women's integration. The responses indicate that the construction industry still displays inertia and conservatism, and that the social partners coroborate rather than counter this. They express a "discourse" of gender equality, but this does not automatically lead to equal opportunity......This article explores the social partners' role in a gender quality agenda in construction at skilled operative level. It draws on a survey of the European construction social partners that investigated the presence of women in skilled trades and the policies, collective agreements and practices...... policies or programmes. The social partners have a platform to make inroads and to change the industry from within, but need further encouragement to put this on their agenda....

  14. Management of climatic heat stress risk in construction: a review of practices, methodologies, and future research.

    Climatic heat stress leads to accidents on construction sites brought about by a range of human factors emanating from heat induced illness, and fatigue leading to impaired capability, physical and mental. It is an occupational characteristic of construction work in many climates and the authors take the approach of re-engineering the whole safety management system rather than focusing on incremental improvement, which is current management practice in the construction industry. From a scientific viewpoint, climatic heat stress is determined by six key factors: (1) air temperature, (2) humidity, (3) radiant heat, and (4) wind speed indicating the environment, (5) metabolic heat generated by physical activities, and (6) "clothing effect" that moderates the heat exchange between the body and the environment. By making use of existing heat stress indices and heat stress management processes, heat stress risk on construction sites can be managed in three ways: (1) control of environmental heat stress exposure through use of an action-triggering threshold system, (2) control of continuous work time (CWT, referred by maximum allowable exposure duration) with mandatory work-rest regimens, and (3) enabling self-paced working through empowerment of employees. Existing heat stress practices and methodologies are critically reviewed and the authors propose a three-level methodology for an action-triggering, localized, simplified threshold system to facilitate effective decisions by frontline supervisors. The authors point out the need for "regional based" heat stress management practices that reflect unique climatic conditions, working practices and acclimatization propensity by local workers indifferent geographic regions. The authors set out the case for regional, rather than international, standards that account for this uniqueness and which are derived from site-based rather than laboratory-based research.

    Full Text Available Although significant changes at the social, demographic, technological and workforce levelshave transformed the relationship between family and work, these changes have notbeen reflected in the employment practices of many construction companies. Many of thejob and organisational factors found to be negatively associated with family functioning arepertinent to construction professionals. Staff are expected to work long hours in demandingroles and this, combined with job insecurity and frequent relocation, means that familylife and individual well-being can be compromised. A growing body of research has foundthat the implementation of family-friendly work policies and practices can lead to greaterproductivity, lower attrition rates and higher morale in the workplace. In addition providinga work environment that is supportive of workers' family roles can help to alleviate workrelatedmental health problems.This paper outlines the changing demographic trends and societal attitudes that are makingindividuals and organisations question current work cultures and structures. Optionsfor making the construction industry a more family-friendly work environment are considered.All professionals, regardless of their age, gender and family responsibilities, canbenefit from these initiatives. The paper concludes by discussing the implications of theseissues for construction companies and future research work.

    This article describes the development of a dynamic culturally constructed clinical practice model for HIV/STI prevention, the Narrative Intervention Model (NIM), and illustrates its application in practice, within the context of a 6-year transdisciplinary research program in Mumbai, India. Theory and research from anthropology, psychology, and public health, and mixed-method ethnographic research with practitioners, patients, and community members, contributed to the articulation of the NIM for HIV/STI risk reduction and prevention among married men living in low-income communities. The NIM involves a process of negotiation of patient narratives regarding their sexual health problems and related risk factors to facilitate risk reduction. The goal of the NIM is to facilitate cognitive-behavioral change through a three-stage process of co-construction (eliciting patient narrative), deconstruction (articulating discrepancies between current and desired narrative), and reconstruction (proposing alternative narratives that facilitate risk reduction). The NIM process extends the traditional clinical approach through the integration of biological, psychological, interpersonal, and cultural factors as depicted in the patient narrative. Our work demonstrates the use of a recursive integration of research and practice to address limitations of current evidence-based intervention approaches that fail to address the diversity of cultural constructions across populations and contexts.

    Full Text Available Construction waste management (CWM has received worldwide attention for some time. As a result, a plethora of research, investigating a wide array of CWM issues such as their profiles, practices, and performance, has been reported in individual economies around the globe. However, a cross-jurisdictional comparison of these issues is limitedly presented in the literature despite its importance to benchmarking performance and identifying best CWM practices in the context of globalization whereby knowledge sharing has already transcended traditional country boundaries. The aim of this ex post facto research is to compare CWM profiles, practices, and performance in Australia, Europe (Europe refers to EU-27 member countries in the European Union, including Belgium, France, Germany, Italy, Luxembourg, Netherlands, Denmark, Great Britain, Ireland, Portugal, Spain, Greece, Austria, Finland, Sweden, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Slovakia, Slovenia, Malta, Cyprus, Bulgaria, and Romania., Hong Kong, and the United Kingdom at a national-level, with a view to facilitating CWM knowledge sharing internationally. It does so by triangulating empirical data collected from various national statistical yearbooks with research papers and professional reports on CWM in these economies. It is found that in producing one million (US dollars’ work, construction contributes a volume of solid waste ranging from 28 to 121 tons among countries. Conscientious CWM practices can make a significant difference in reducing, reusing, or recycling construction waste, as evident in the large variation in the CWM performance. While it might be oversimplified to conclude that the best practices in one country can be applied in another, the research provides insightful references into sharing CWM knowledge across boundaries.

    Full Text Available Preservation of agricultural land as an imperative of prosperity of agriculture of the Republic of Serbia needs to be observed through causal questions as well, such as change of purpose of agricultural land into construction land, which is necessarily followed by conversion, a decade-long problem. Insufficiently resolved current questions of the aforementioned within legislative framework open up the possibility for improper use and exploitation of agricultural land. It is necessary to regulate the issue of conversion of construction land by legislative regulations i.e. altering use rights into property rights on construction land, and by doing so, open the way to investments in the Republic of Serbia. With the analysis of the effects of conversion and the adoption of a special law on this issue, construction activity would further prosper. The aim of this paper is to assess adequately the current problems of consumption, preservation and actual implementation of transferring agricultural land to construction land, with a view of the facts, practices and tendencies.

    2017-06-01

    Full Text Available In this article urban architecture, acting as a «natural physical borders of mankind», creates a certain discourse of social practices that construct and define reality, forming views and values. Moreover, that discourse can be deconstructed and problematized through representation of the urban architecture, which provides an opportunity to explore different ways of forming those social practices among citizens. Thus, the main idea of this study is to examine the way in which social practices could be seen as a reflection of citizen’s actions, which, on the one hand, are set up by the urban construction as an objective structure and, on the other hand, modal behavior which are formed by the influence of a certain structure of thought and ideas. To implement the objectives of the study, we use the discourse analysis as a method of analyzing the meanings through which an attempt of deconstruction of practices of urban life is made, the analysis of themes which are brought up to reveal the featured characteristics and values of urban architecture and ways of its coding.

    2017-06-01

    This article is the first to describe the discoursal construction of an adolescent community of practice (CoP) in a non-school setting. CoPs can provide optimal learning environments. The adolescent community centered around science journalism and positioned itself dichotomously in relationship to school literacy practices. The analysis focuses on recordings from a panel-style research interview from an early implementation of the Science Literacy Through Science Journalism (SciJourn) project. Researchers trained high school students participating in a youth development program to write science news articles. Students engaged in the authentic practices of professional science journalists, received feedback from a professional editor, and submitted articles for publication. I used a fine-grained critical discourse analysis of genre, discourse, and style to analyze student responses about differences between writing in SciJourn and in school. Students described themselves as agentic in SciJourn and passive in school, using an academic writing discourse of deficit to describe schooling experiences. They affiliated with and defined a SciJourn CoP, constructing positive journalistic identities therein. Educators are encouraged to develop similar CoPs. The discursive features presented may be used to monitor the development of communities of practice in a variety of settings.

    Full Text Available Librarian-teacher cooperation is essential for the integration of information literacy into course syllabi. Therefore, a common theoretical and methodological platform is needed. As librarians at Kristianstad University we have had the opportunity to develop such a platform when teaching information literacy in a basic course for teachers in higher education pedagogy. Information literacy is taught in context with academic writing, distance learning and teaching, and development of course syllabi. Constructive Alignment in Theory: We used constructive alignment in designing our part of the course. John Biggs’ ideas tell us that assessment tasks (ATs should be aligned to what is intended to be learned. Intended learning outcomes (ILOs specify teaching/learning activities (TLAs based on the content of learning. TLAs should be designed in ways that enable students to construct knowledge from their own experience. The ILOs for the course are to have arguments for the role of information literacy in higher education and ideas of implementing them in TLAs. The content of learning is for example the concept of information literacy, theoretical perspectives and constructive alignment for integration in course syllabi. TLAs are written pre-lecture reflections on the concept of information literacy, used as a starting point for the three-hour seminar. Learning reflections are written afterwards. The AT is to revise a syllabus (preferably using constructive alignment for a course the teacher is responsible for, where information literacy must be integrated with the other parts and topics of the course. Constructive Alignment in Practice: Using constructive alignment has taught us that this model serves well as the foundation of the theoretical and methodological platform for librarian-teacher cooperation when integrating information literacy in course syllabi. It contains all important aspects of the integration of information literacy in course

    Safety climate, a group-level measure of workers' perceptions regarding management's safety priorities, has been suggested as a key predictor of safety outcomes. However, its relationship with actual injury rates is inconsistent. We posit that safety climate may instead be a parallel outcome of workplace safety practices, rather than a determinant of workers' safety behaviors or outcomes. Using a sample of 25 commercial construction companies in Colombia, selected by injury rate stratum (high, medium, low), we examined the relationship between workers' safety climate perceptions and safety management practices (SMPs) reported by safety officers. Workers' perceptions of safety climate were independent of their own company's implementation of SMPs, as measured here, and its injury rates. However, injury rates were negatively related to the implementation of SMPs. Safety management practices may be more important than workers' perceptions of safety climate as direct predictors of injury rates. © 2017 Wiley Periodicals, Inc.

    The problem of nurses' professional identity continues to be seen in the disjunction between theoretical training and clinical placements. Moreover, it is not known how nursing students perceive these contradictions or how this discrepancy influences the construction of professional identity. To gain insight into nursing students' perception of their theoretical and practical training and how this training influences the process of constructing their professional identity. Qualitative, ethnographic study. Third-year nursing students at the l'Escola Universitària d'Infermeria Vall d'Hebron de Barcelona. Participant observation was conducted in the hospital setting and primary care. Discussion groups were held. The constant comparative method was used for the analysis. The study adhered to the criteria of credibility, transferability, dependability and confirmability. Students believed that both theoretical and practical trainings were indispensable. Nevertheless, clinical placements were considered essential to confer sense to the theory and to shape their identity, as they helped student nurses to experience their future professional reality and to compare it with what they had been taught in theoretical and academic classes. The role of the clinical placement mentor was essential. With regard to theory, the skills developed in problem-based learning gave novice nurses' confidence to approach the problems of daily practice and new situations. Equally, this approach taught them to reflect on what they did and what they were taught and this ability was transferred to the clinical setting. For students, both strategies (theory and practice) are vital to nursing education and the construction of a professional identity, although pride of place is given to clinical placements and mentors. The skills developed with problem-based learning favor active and reflective learning and are transferred to learning in the clinical setting. Copyright © 2015 Elsevier Ltd. All

    Full Text Available As you know, high-rise construction is an indicator of the practical implementation of advanced innovative technologies in the construction industry of the country. High-rise building inevitably comes to the big cities, in connection with the shortage and value of land. The life cycle of any construction project, including high-rise buildings consists of chains: of engineering survey - design-construction-operation. In the process of operation of a tall building, decisions about major repairs or reconstruction of a building are made for decision-making on further use. This article describes methods of assessing the consumer quality of high-rise residential buildings and the establishment of prices based on consumer characteristics of a tall residential building. It is proposed to assess the premises under their quality characteristics. The study was conducted to establish the influence of individual, comprehensive and integral indicators of comparable quality for effective quality living spaces. Simultaneously, there was established a relationship of quality with the consumer cost of housing, ultimately with the potential needs of owners, tenants of the home, lessor dwelling, or buyers of residential properties and other participants in the residential real estate market. This relationship further creates consumer requirements to quality standard of premises at a certain stage of socio-economic development.

    Residential air conditioning (AC) represents a challenging load for many electric utilities with poor load factors. Mechanical precooling improves the load factor by shifting cooling operation from on-peak to off-peak hours. This provides benefits to utilities and the electricity grid, as well as to occupants who can take advantage of time-of-use (TOU) electricity rates. Performance benefits stem from reduced compressor cycling, and shifting condensing unit operation to earlier periods of the day when outdoor temperatures are more favorable to operational efficiency. Finding solutions that save energy and reduce demand on the electricity grid is an important national objective and supports key Building America goals. The Alliance for Residential Building Innovation team evaluated mechanical AC precooling strategies in homes throughout the United States. EnergyPlus modeling was used to evaluate two homes with different performance characteristics in seven climates. Results are applicable to new construction homes and most existing homes built in the last 10 years, as well as fairly efficient retrofitted homes. A successful off-peak AC strategy offers the potential for increased efficiency and improved occupant comfort, and promotes a more reliable and robust electricity grid. Demand response capabilities and further integration with photovoltaic TOU generation patterns provide additional opportunities to flatten loads and optimize grid impacts.

    For the past few years, disasters like earthquakes, landslides, mudslides, tsunamis, and traffic accidents have occurred with an ever-growing frequency, coverage, and intensity greatly beyond the expectation of the public. In order to respond effectively to disasters and to reduce casualties and property damage, countries around the world have invested more efforts in the theoretical study of emergency medicine and the construction of emergency medical rescue forces. Consequently, emergency medical rescue teams of all scales and types have come into being and have played significant roles in disaster response work. As the only state-level emergency medical rescue force from the Chinese People's Armed Police Forces, the force described here has developed, through continuous learning and practice, a characteristic mode in terms of grouping methods, equipment system construction, and training.

    Patients with chronic obstructive pulmonary disease (COPD) constitute a potentially susceptible group towards environmental exposures such as livestock farm emissions, given their compromised respiratory health status. The primary aim of this study was to examine the association between livestock exposure and comorbidities and coexisting symptoms and infections in COPD patients. Data were collected from 1828 COPD patients (without co-occurring asthma) registered in 23 general practices and living in a rural area with a high livestock density. Prevalence of comorbid diseases/disorders and coexisting symptoms/infections were based on electronic health records from the year 2012. Various indicators of individual exposure to livestock were estimated based on residential addresses, using a geographic information system. At least one comorbid disorder was present in 69% of the COPD patients (especially cardiac disorders and depression, while 49% had at least one coexisting symptom and/or infection (especially upper respiratory tract infections, respiratory symptoms and pneumonia). Half of the COPD-patients resided less than 500m of the nearest farm. Some positive as well as inverse associations were found between the examined outcomes and exposure estimates, although not consistent. Despite the high prevalence of coexisting chronic and acute conditions presented in primary care by in COPD patients, this investigation found no convincing evidence for an association with livestock exposure estimates. There is a need for a replication of the present findings in studies with a longitudinal design, on different groups of potentially susceptible patients. Future research should also elucidate the biological plausibility of possible protective effects of exposure. Copyright © 2017 Elsevier GmbH. All rights reserved.

    This study proposes and analyzes the construct validity and internal consistency of the Leisure Practices Scale (EPL). This survey seeks to identify the preferences and involvement in in different leisure practices in adults. The instrument was formed based on the cultural leisure content (artistic, manual, physical, sports, intellectual, social, tourist, virtual and contemplation/leisure). The validation process was conducted with: a) content analysis by leisure experts, who evaluated the instrument for clarity of language and practical relevance, which allowed the calculation of the content validity coefficient (CVC); b) reproducibility test-retest with 51 subjects to calculate the temporal variation coefficient; c) internal consistency analysis with 885 participants. The evaluation presented appropriate coefficients, both with respect to language clarity (CVCt = 0.883) and practical relevance (CVCt = 0.879). The reproducibility coefficients were moderate to excellent. The scale showed adequate internal consistency (0.72). The EPL has psychometric quality and acceptable values in its structure, and can be used to investigate adult involvement in leisure activities.

Research of trends in risk management was conducted using studies from the EBSCO database that were published in the period from 1999 to 2015. The focus included the development of two terms, namely traditional and holistic approach to risk management as well as to uncertainty and opportunity management. The trend of leading standards in the field of project management, PMBoK and ISO 31000 indicated full support for the modernization of risk management that focused on the risks as well as potential opportunities in the project. The findings also revealed that the global practices continued to lack awareness of risk management and its benefits for project goals. A similar situation was found in Croatia by observing project management practices in two case studies, namely Project Zagrebačka obala in Rijeka and a Project of SEECEL Zagreb. Primarily, the lack of education and communication between experts are important issues requiring attention in practice and academics. It is necessary to gradually introduce standards over time to prepare for progress in managing uncertainties and adopting more holistic approaches.

    Love, Peter E D; Smith, Jim; Teo, Pauline

    2018-05-01

    Error management theory is drawn upon to examine how a project-based organization, which took the form of a program alliance, was able to change its established error prevention mindset to one that enacted a learning mindfulness that provided an avenue to curtail its action errors. The program alliance was required to unlearn its existing routines and beliefs to accommodate the practices required to embrace error management. As a result of establishing an error management culture the program alliance was able to create a collective mindfulness that nurtured learning and supported innovation. The findings provide a much-needed context to demonstrate the relevance of error management theory to effectively address rework and safety problems in construction projects. The robust theoretical underpinning that is grounded in practice and presented in this paper provides a mechanism to engender learning from errors, which can be utilized by construction organizations to improve the productivity and performance of their projects.

  17. Investigating Assessment Bias for Constructed Response Explanation Tasks: Implications for Evaluating Performance Expectations for Scientific Practice

    Science.gov (United States)

    Federer, Meghan Rector

    Assessment is a key element in the process of science education teaching and research. Understanding sources of performance bias in science assessment is a major challenge for science education reforms. Prior research has documented several limitations of instrument types on the measurement of students' scientific knowledge (Liu et al., 2011; Messick, 1995; Popham, 2010). Furthermore, a large body of work has been devoted to reducing assessment biases that distort inferences about students' science understanding, particularly in multiple-choice [MC] instruments. Despite the above documented biases, much has yet to be determined for constructed response [CR] assessments in biology and their use for evaluating students' conceptual understanding of scientific practices (such as explanation). Understanding differences in science achievement provides important insights into whether science curricula and/or assessments are valid representations of student abilities. Using the integrative framework put forth by the National Research Council (2012), this dissertation aimed to explore whether assessment biases occur for assessment practices intended to measure students' conceptual understanding and proficiency in scientific practices. Using a large corpus of undergraduate biology students' explanations, three studies were conducted to examine whether known biases of MC instruments were also apparent in a CR instrument designed to assess students' explanatory practice and understanding of evolutionary change (ACORNS: Assessment of COntextual Reasoning about Natural Selection). The first study investigated the challenge of interpreting and scoring lexically ambiguous language in CR answers. The incorporation of 'multivalent' terms into scientific discourse practices often results in statements or explanations that are difficult to interpret and can produce faulty inferences about student knowledge. The results of this study indicate that many undergraduate biology majors

    The rapid economic development has increased the demand for construction of infrastructure and facilities globally. Sustainable development and globalization are the new ‘Zeitgeist’ of the 21st century. In order to implement these projects successfully and to meet the functional aim of the projects within their lifetime, an efficient project management practice is needed. The aim of this study is to identify the critical success factors (CSFs) and the extent of use of project management practice which affects project success, especially during the implementation stage. Data were obtained from self-administered questionnaires with 232 respondents. A mixed method of data collection was adopted using semi-structured interview and questionnaire approach. The result of the analysis of data obtained showed that new and emerging criteria such as customer satisfaction, competency of the project team, and performance of subcontractors/suppliers are becoming measures of success in addition to the classic iron triangle’s view of time, cost and quality. An insight on the extent of use of different project management practice in the industry was also achieved from the study.

    In social psychology, evaluative expressions have traditionally been understood in terms of their relationship to, and as the expression of, underlying 'attitudes'. In contrast, discursive approaches have started to study evaluative expressions as part of varied social practices, considering what such expressions are doing rather than their relationship to attitudinal objects or other putative mental entities. In this study the latter approach will be used to examine the construction of food and drink evaluations in conversation. The data are taken from a corpus of family mealtimes recorded over a period of months. The aim of this study is to highlight two distinctions that are typically obscured in traditional attitude work ('subjective' vs. 'objective' expressions, category vs. item evaluations). A set of extracts is examined to document the presence of these distinctions in talk that evaluates food and the way they are used and rhetorically developed to perform particular activities (accepting/refusing food, complimenting the food provider, persuading someone to eat). The analysis suggests that researchers (a) should be aware of the potential significance of these distinctions; (b) should be cautious when treating evaluative terms as broadly equivalent and (c) should be cautious when blurring categories and instances. This analysis raises the broader question of how far evaluative practices may be specific to particular domains, and what this specificity might consist in. It is concluded that research in this area could benefit from starting to focus on the role of evaluations in practices and charting their association with specific topics and objects.

    The purposes of the study were: (1) to examine the effectiveness of the Iowa Chautauqua Professional Development Program (ICPDP) in moving elementary science teachers toward the use of more constructive teaching practices and (2) to investigate the effectiveness of different levels of teaching practices, especially in terms of a sample of teachers achieving "expert" state at the end of program compared with some attaining only with "competent" level. The variables considered were their perceptions of their own classroom practices, stated philosophy of teaching and learning, and their actual classroom practices and question asking behaviors observed via videotape recording. Structured questionnaires, focus group interviews, teacher reflections, and examination of lesson modules were used to collect data from thirty-three K-5 in-service teachers who were involved in a one-year ICPDP. Qualitative and quantitative analyses of data revealed that: (1) Teacher perceptions regarding their teaching and learning, and their actual teaching practices in classroom in terms of constructivist approaches were significantly changed after participation in the ICPDP. (2) Teacher perceptions of their classroom practices and stated philosophies of teaching and learning have a great affect on their actual practices that can be observed. (3) Teacher stated philosophies of teaching and learning significantly influence the quantity and quality of their use of questions in their classrooms. (4) The "expert" teachers accept students' alternative answers and deliberately ask high cognitive level questions that enable students to think critically and to guide them based on what the students are thinking. Alternatively, the "competent" teachers do not follow student responses and used questions which do not help students to understand their current level of understanding nor encourage students to reflect on their own thinking. (5) The role of "expert" teacher is more geared toward challenging

    Crisis communications can play an important role in mitigating, or exacerbating, the psychological and behavioral reactions to critical incidents and disasters. Effective crisis communications can serve to mitigate anxiogenesis and direct rapid and focused rescue, recovery, and rehabilitative operations. Ambiguous and/or deceptive communications can serve to worsen mental health reactions and delay operational response and recovery (Everly, Strouse, & Everly, 2010). It seems, therefore, that inquiry into the content of acute crisis communications would be warranted Said more simply, given limited time, cryptic messaging in social media, and the "sound bite" mentality that seems to govern news dissemination, it is important to identify the most important content to convey in the wake of critical incidents and disasters. This paper reports on a pilot investigation into "best practices" for the construction of acute crisis communications.

    Since 2001, residencies have struggled with teaching and assessing systems-based practice (SBP). One major obstacle may be that the competency alone is not sufficient to support assessment. We believe the foundational construct underlying SBP is systems thinking, absent from the current Accreditation Council for Graduate Medical Education competency language. Systems thinking is defined as the ability to analyze systems as a whole. The purpose of this article is to describe psychometric issues that constrain assessment of SBP and elucidate the role of systems thinking in teaching and assessing SBP. Residency programs should incorporate systems thinking models into their curricula. Trainees should be taught to understand systems at an abstract level, in order to analyze their own healthcare systems, and participate in quality and patient safety activities. We suggest that a developmental trajectory for systems thinking be developed, similar to the model described by Dreyfus and Dreyfus.

    1.1 The purpose of this practice is to provide design and construction guidelines for contamination controlled facilities used in the assembly and integration of aerospace hardware. The guidelines herein are intended to ensure that the facilities, when used properly, will meet the cleanliness requirements of aerospace hardware and processes. The objective is to limit contamination due to the deposition of particulate and molecular contaminants on flight hardware surfaces. 1.2 One cleanliness classification of a facility is the airborne particle concentrations in accordance with ISO 14644-1 and 14644-2. Airborne particle concentrations in accordance with FED-STD-209E are included for reference. This simple classification is inadequate to describe a facility that will support the assembly and integration of spacecraft. The extended duration of hardware exposure during fabrication and testing, the sensitivity of the hardware to hydrocarbons and other molecular contaminants, and the changing requirements during ...

    Theoretical results are presented which show the performance likely to result from using differing antenna heights, lengths and wire sizes and from operating with different ground conductivities. These studies were undertaken to provide practical advice for constructors and operators. Design parameters can be easily obtained with the aid of computer programs and an antenna can be rapidly constructed from readily available materials. Directivity can be increased by adding more elements, either in parallel or on a radial basis. A particular performance can be achieved with great latitude in the parameters. Good low angle performance can be achieved without large ground screens. A directional array can be made by switching between a number of elements set up on different bearings.

    2009-01-01

    The National Pollutant Discharge Elimination System (NPDES) Phase II requires construction activities to have erosion and sediment control best management practices (BMPs) designed and installed for site storm water management. Although BMPs are specified on storm water pollution prevention plans (SWPPPs) as part of the construction general permit (GP), there is little evidence in the research literature as to how BMPs perform or should be designed. The objectives of this study were to: (i) comparatively evaluate the performance of common construction activity erosion control BMPs under a standardized test method, (ii) evaluate the performance of compost erosion control blanket thickness, (iii) evaluate the performance of compost erosion control blankets (CECBs) on a variety of slope angles, and (iv) determine Universal Soil Loss Equation (USLE) cover management factors (C factors) for these BMPs to assist site designers and engineers. Twenty-three erosion control BMPs were evaluated using American Society of Testing and Materials (ASTM) D-6459, standard test method for determination of ECB performance in protecting hill slopes from rainfall induced erosion, on 4:1 (H:V), 3:1, and 2:1 slopes. Soil loss reduction for treatments exposed to 5 cm of rainfall on a 2:1 slope ranged from-7 to 99%. For rainfall exposure of 10 cm, treatment soil loss reduction ranged from 8 to 99%. The 2.5 and 5 cm CECBs significantly reduced erosion on slopes up to 2:1, while CECBs or= 4:1 when rainfall totals reach 5 cm. Based on the soil loss results, USLE C factors ranged from 0.01 to 0.9. These performance and design criteria should aid site planners and designers in decision-making processes.

    During first language acquisition (L1), children need to gather knowledge about the speech sounds and grammar of their mother tongue. Furthermore, communication skills require an adequate vocabulary. Individual profiles of vocabulary acquisition can vary considerably. However, actively using around 50 words by the age of 24 months is considered a milestone in first language acquisition. This is usually followed by the so-called vocabulary spurt, a rapid increase in lexical knowledge. This article provides an overview of the theories of lexical development and discusses how the acquisition of vocabulary may be explained. A selective literature search was conducted in PubMed and Scopus. Current textbooks were also considered. In order to acquire new words, a child has to identify what the new string of speech sounds refers to. The child has to construct a valid concept of the word and subsequently store both word and concept into long-term memory. Several theories have been put forward to explain lexicon organization, the acquisition of concepts and the mechanisms underlying the so-called fast mapping phenomenon in particular. All of these attempt to explain the phenomenon of lexicon acquisition in terms of a model scheme. In the context of the fast mapping mechanism, constraints and assumptions, cognitive, intentionalist and emergence-based theories are discussed. Knowledge of the different theories of vocabulary acquisition is mandatory to understand the construction of the tests used to assess vocabulary skills in clinical practice and to apply these appropriately.

    Full Text Available Knowledge management (KM could be described as a management system that supports the creation, sharing and retrieving of valued information, expertise and insight within and across communities of people and related organizations using information and communication technologies and hence it is a combination of the effective application of information technlogy and management of human resources. KM is becoming a core competitive factor in construction operations. This paper presents the results of two case studies of KM practices in large AEC (architecture, engineering and construction companies through desk-top study and semi-structured interviews. The results indicate that implementing KM in AEC companies leads to competitive advantages and improved decision-making, problem solving and business performance. The results also indicateed that while technology plays an important role, top management commitment, total employee involvement, performance assessment and the culture of knowledge-learning and sharing must be considered when implementing KM. Therefore it is suggested that the implementation of KM should incorporate the company's vision, work processes, technology and culture, to improve the ability of knowledge creating, capturing, sharing, retrieving and ultimately, to improve the company's competitive advantage, decision making, problem solving and innovation.

    Ontology is one of the key components in semantic webs. It contains the core knowledge for an effective search. However, building ontology requires the carefully-collected knowledge which is very domain-sensitive. In this work, we present the practice of ontology construction for a case study of health tourism in Thailand. The whole process follows the METHONTOLOGY approach, which consists of phases: information gathering, corpus study, ontology engineering, evaluation, publishing, and the application construction. Different sources of data such as structure web documents like HTML and other documents are acquired in the information gathering process. The tourism corpora from various tourism texts and standards are explored. The ontology is evaluated in two aspects: automatic reasoning using Pellet, and RacerPro, and the questionnaires, used to evaluate by experts of the domains: tourism domain experts and ontology experts. The ontology usability is demonstrated via the semantic web application and via example axioms. The developed ontology is actually the first health tourism ontology in Thailand with the published application.

  13. The Evolving Law of Disputed Relocation: constructing inner-city renewal practices in Shanghai, 1990-2005.

    Shih, Mi

    2010-01-01

    The forceful pursuit of inner-city renewal in Shanghai since the early 1990s has to a great extent achieved spatial modernization, but at the same time it has given rise to increasing conflicts over residential relocation. Using law as a prism through which to examine the dialectic relationship between renewal practices and disputed relocation, this article argues that the series of unprecedented enactments in law that have taken place during this period have both paved the way for real estate market expansion and been a significant source of relocation disputes in Shanghai. Rather than viewing law as simply given and determinate, the article traces the regulatory regime's codification of property practices as a means of actively responding to the requirements of the real estate market. Under large-scale renewal practices, residents' legal rights of "return settlement" (huiban) in inner-city areas were largely denied in the early 1990s, before being effectively abolished by the adoption of monetary compensation for displacement in the 2000s. The evolving law on property practices has greatly shaped the process of disputed relocation while simultaneously posing a potential challenge to China's use of law for market-oriented development.

    This paper sought to assess organizational safety practices at three different levels of hierarchical workplace structure and to examine their association with injury outcomes among construction apprentices. Using a cross-sectional sample of 1,775 construction apprentices, three measures of organizational safety practice were assessed: contractor-, steward-, and coworker-safety practice. Each safety practice measure was assessed using three similar questions (i.e., on-the-job safety commitment, following required or recommended safe work practices, and correcting unsafe work practices); the summed average of the responses ranged from 1 to 4, with a higher score indicating poorer safety practice. Outcome variables included the prevalence of four types of musculoskeletal pain (i.e., neck, shoulder, hand, and back pain) and injury-related absence. In adjusted analyses, contractor-safety practice was associated with both hand pain (OR: 1.27, 95 % CI: 1.04, 1.54) and back pain (OR: 1.40, 95 % CI: 1.17, 1.68); coworker-safety practice was related to back pain (OR: 1.42, 95 % CI: 1.18, 1.71) and injury-related absence (OR: 1.36, 95 % CI: 1.11, 1.67). In an analysis that included all three safety practice measures simultaneously, the association between coworker-safety practice and injury-related absence remained significant (OR: 1.68, 95 % CI: 1.20, 2.37), whereas all other associations became non-significant. This study suggests that organizational safety practice, particularly coworker-safety practice, is associated with injury outcomes among construction apprentices.

  15. Constructing engineers through practice: Gendered features of learning and identity development

    Science.gov (United States)

    Tonso, Karen L.

    How do women and men student engineers develop an engineering identity (a sense of belonging, or not), while practicing "actual" engineering? What are the influences of gender, learning and knowledge, relations of power, and conceptions of equality on cultural identity development? I studied these issues in reform-minded engineering design classes, courses organized around teaching students communications, teamwork, and practical engineering. Engineering-student cultural identity categories revealed a status hierarchy, predicated on meeting "academic" criteria for excellence, and the almost total exclusion of women. While working as an engineering colleague on five student teams (three first-year and two senior) and attending their design classes, I documented how cultural identities were made evident and constructed in students' practical engineering. Design projects promoted linking academic knowledge with real-world situations, sharing responsibilities and trusting colleagues, communicating engineering knowledge to technical and non-technical members of business communities, and addressing gaps in students' knowledge. With a curriculum analysis and survey of students' perceptions of the differences between design and conventional courses, I embedded the design classes in the wider campus and found that: (1) Engineering education conferred prestige, power, and well-paying jobs on students who performed "academic" engineering, while failing to adequately encourage "actual" engineering practices. High-status student engineers were the least likely to perform "actual" engineering in design teams. (2) Engineering education advanced an ideology that encouraged its practitioners to consider men's privilege and women's invisibility normal. By making "acting like men act" the standards to which engineering students must conform, women learned to put up with oppressive treatment. Women's accepting their own mistreatment and hiding their womanhood became a condition of

    To comprehensively review the Community of Practice literature from nursing contexts to explore whether and how these communities contribute to the social construction of nurse educator professional identity. Due to the wide scope of predominately qualitative literature on the topic, papers were analysed and themed inductively. CINAHL, MEDLINE, COCHRANE, EBSCO databases, Emerald, Proquest & Google Scholar. These online databases were searched for relevant peer-reviewed journal papers in the English language with no date range specified. The search terms 'nurs* educator' and 'nurs* teacher' were combined with each of the terms 'communit* of practice', 'identity' and 'role' resulting in 293 peer-reviewed journal papers. Where abstracts were missing, introductory and background sections were skimmed for related content. Papers that made incidental reference to either professional identity or a Community of Practice were excluded. In total, 63 primary study or discussion papers were found to have a focus on nurse educator identity and/or communities of practice in healthcare contexts. Papers specifically focused on communities of practice in nursing (n=33) could only be found from the last 10 years (2005-2015). Only five of these focused on nurse educators. Community of Practice theory and the professional teaching literature offers collaborative and active ways for nurse educators to further develop their professional identities. Despite the emergence of communities of practice in the nursing literature, further studies are required to explore how such a construct can facilitate the social construction of nurse educator professional identity.

    Little is known about how social aspects of the work environment influence exposures or safety practices affecting young construction workers. Our objective was to investigate whether working on a construction site with a small number of workers (≤10 vs. 11-50) or having a family-firm connection (working in a family-owned firm or one in which a family member also works) impacts hazard exposures and safety practices. Participants included 187 North Carolina construction workers 14 to 17 years old who were surveyed about their jobs. We conducted stratified analyses using cross-tabulations and chi-square statistics to measure associations between workgroup size (i.e., the total number of workers on a jobsite) and family-firm connections (yes/no) and hazard exposures (e.g., saws) and safety practices (e.g., supervision). Having a family-firm connection was associated with fewer hazard exposures and greater safety practices. Youth who worked on jobsites with a larger workgroup (11-50 workers) reported more hazards but also more safety practices. Family-firm connections, in particular, may have a protective effect for youth in construction. Even though the statistical significance of our findings on workgroup size was limited in places, the pattern of differences found suggest that further research in this area is warranted.

    Full Text Available The implementation of No Agricultural Cooperatives constitutes an economic solution to the current context of Cuba. Its real impact on the lives of thousands of Cubans and Cubans validates the guarantee of this movement even in the experimental stage, establishing a balance between its economic and social development. In correspondence, the present investigation is elaborated with the objective of showing the experiences and good practices that the Non-Agricultural Cooperative of Construction Services, Scaffolds and Cofres has had in terms of social responsibility and local development. The following methods and techniques were used: documentary review, non-participant observation, interviews and survey, which allowed for an analysis demonstrating that the growth of economic indicators should also favor the transformation of society, including that of partners, members and their families; as well as in the awareness of a social economy based on cooperativism. The need to implement a social accounting system in non-agricultural cooperatives that allows measuring its impact on the conception of a social management model was demonstrated.

  20. Accountability: a missing construct in models of adherence behavior and in clinical practice.

    Piano lessons, weekly laboratory meetings, and visits to health care providers have in common an accountability that encourages people to follow a specified course of action. The accountability inherent in the social interaction between a patient and a health care provider affects patients' motivation to adhere to treatment. Nevertheless, accountability is a concept not found in adherence models, and is rarely employed in typical medical practice, where patients may be prescribed a treatment and not seen again until a return appointment 8-12 weeks later. The purpose of this paper is to describe the concept of accountability and to incorporate accountability into an existing adherence model framework. Based on the Self-Determination Theory, accountability can be considered in a spectrum from a paternalistic use of duress to comply with instructions (controlled accountability) to patients' autonomous internal desire to please a respected health care provider (autonomous accountability), the latter expected to best enhance long-term adherence behavior. Existing adherence models were reviewed with a panel of experts, and an accountability construct was incorporated into a modified version of Bandura's Social Cognitive Theory. Defining accountability and incorporating it into an adherence model will facilitate the development of measures of accountability as well as the testing and refinement of adherence interventions that make use of this critical determinant of human behavior.

    Full Text Available Purpose. Analysis is focused on the study of theoretical and methodological preconditions of social integrity phenomenon research. Trends in the conceptual base of modern social theory are focused on the research of social phenomenon, the study of the conditions and mechanisms for the development of sociality. This suggests the need to find new interpretive schemes. The methodology of political philosophy in the analysis of sociality was limited. This theory has brought the phenomenon of co-existence to the aspect of political discourse. In this regard, the reference to the existence of human co-beingness, mechanisms and modus of its formation is a necessary methodological step. It allows you to draw a parallel between the phenomenon of social integrity and totality. Existential installation integrity, unity of individual and social order is invested in the social context as a human desire to know the surrounding reality. Cognition is installation on the penetration deep into the object, understanding its nature. Cognition opens up the prospect of being a harmonious personality. Existential knowledge focuses on the identity of the co-existence and serves only the prospect of overcoming the limitations of the totality. The potential of this phenomenon allows penetration of rigid rational scheme of classical political methodology, introducing the community as a spiritual practice, the experience of communitas. Thus, as the research methodology used social integrity existential approach, which actualizes the potential of the spiritual foundations of co-existence. This methodological step allows disclosing sociality at a deep level of analysis as a spiritual practice to others, modus being-cognition of the human reality. Originality of this work is to extend the of heuristic possibilities of social theory in the analysis of the social problems aspect with the purpose construction of integrated research methodology problems. Conclusions. Thus, the

However, despite 20 years of discourse on pain and dementia, pain is still undetected or misinterpreted in people with dementia in residential aged care facilities, particularly those with communication difficulties. Methods: A topical survey typology with semistructured interviews was used to gather attitudes and experiences of staff from 15 RACF across Northern Sydney Local Health District. Results: While pain is proactively assessed and pain charts are used in RACF, this is more often regulatory-driven than patient-driven (eg, prior to accreditation. Identification of pain and need for pain relief was ill defined and poorly understood. Both pharmacological and nonpharmacological regimes were used, but in an ad hoc, variable and unsystematic manner, with patient, staff, and attitudinal obstacles between the experience of pain and its relief.Conclusion: A laborious “pain communication chain” exists between the experience of pain and its relief for people with severe dementia within RACF. Given the salience of pain for older people with dementia, we recommend early, proactive consideration and management of pain in the approach to behaviors of concern. Individualized pain measures for such residents; empowerment of nursing staff as “needs interpreters”; collaborative partnerships with common care goals between patients where possible; RACF staff, doctors, and family carers; and more meaningful use of pain charts to map response to stepped pain protocols may be useful strategies to explore in clinical settings

    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.

    installed-system costs into LCOE, we find that the less-aggressive pathways achieve significant cost reductions, but may not achieve the 2030 LCOE target. On the other hand, both visionary pathways could get very close to (for roof replacement) or achieve (for new construction) the 2030 target. Our analysis has two key implications. First, because installed-system soft cost reductions account for about 65 percent of the LCOE reductions in 2030 for both visionary pathways, residential PV stakeholders may need to emphasize these soft cost reductions to achieve the 2030 target. Second, capturing these savings will likely require considerable innovation in the technologies and business practices employed by the PV industry.

    Construction and demolition waste is often seen as the major contributor to the solid waste stream that is going to landfill, hence, making it the area of focus for improvement. In the construction industry, reuse and recycle principles have been promoted in order to reduce waste and protect the environment. Construction and demolition waste including demolished concrete, bricks and masonry, wood and other materials such as dry wall, glass, insulation, roofing, wire, pipe, rock and soil constitute a significant component of the total waste. Without proper reuse and recycle policies, these construction and demolition wastes would quickly fill all the remaining landfill space, which has already been growing in scarce around this region. Based on the feedback received, on average, a third of respondents said they currently have a lotto benefit from the use of reduce and reuse. In addition, they also agreed that the existing policies help and support the min carrying out the reduce and reuse practices. Respondents also agreed that other stakeholders in the construction industry currently have an excellent awareness in term of implementation of the reduce and reuse in their practices.

The accountability inherent in the social interaction between a patient and a health care provider affects patients’ motivation to adhere to treatment. Nevertheless, accountability is a concept not found in adherence models, and is rarely employed in typical medical practice, where patients may be prescribed a treatment and not seen again until a return appointment 8–12 weeks later. The purpose of this paper is to describe the concept of accountability and to incorporate accountability into an existing adherence model framework. Based on the Self-Determination Theory, accountability can be considered in a spectrum from a paternalistic use of duress to comply with instructions (controlled accountability to patients’ autonomous internal desire to please a respected health care provider (autonomous accountability, the latter expected to best enhance long-term adherence behavior. Existing adherence models were reviewed with a panel of experts, and an accountability construct was incorporated into a modified version of Bandura’s Social Cognitive Theory. Defining accountability and incorporating it into an adherence model will facilitate the development of measures of accountability as well

  17. Chronic Pain as a Hypothetical Construct: A Practical and Philosophical Consideration

    Directory of Open Access Journals (Sweden)

    Daniel M. Doleys

    2017-04-01

    Full Text Available Pain has been defined by the International Association for the Study of Pain (IASP as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage.” Chronic pain is usually described as pain that has persisted for 3–6 months and/or beyond the expected time of healing. The numerical pain rating (NPR is the customary metric and often considered as a proxy for the subjective experience of chronic pain. This definition of pain (chronic has been of significant heuristic value. However, the definition and the models it has spawned tend to encourage the interpretation of pain as a measurable entity and implies that the patient’s experience of pain can be fully comprehended by someone other than the person in pain. Several major models of pain have been scrutinized and found to propagate the notion of pain as a ‘thing’ and fall prey to biomedical reductionism and Cartesian (mind-body dualism. Furthermore, the NPR does not appear to capture the complexity of chronic pain and correlates poorly with other clinically meaningful outcomes. It, and other aspects of the current notion of chronic pain, appear to be an extension of our reliance on the philosophical principles of reductionism and materialism. These and other shortcomings identified in the IASP definition have resulted in an increased interest in a reexamination and possible updating of our view of pain (chronic and its definition. The present paper describes an alternative view of pain, in particular chronic pain. It argues that chronic pain should be understood as a separate phenomenon from, rather than an extension of, acute pain and interpreted as a hypothetical construct (HC. HCs are contrasted to intervening variables (IV and the use of HCs in science is illustrated. The acceptance of the principles of nonlinearity and emergence are seen as important characteristics.

  1. "Judging a body by its cover": young Lebanese-Canadian women's discursive constructions of the "healthy" body and "health" practices.

    Science.gov (United States)

    Abou-Rizk, Zeina; Rail, Geneviève

    2014-02-01

    Our interest stems from the dramatic increase in the number of obesity studies, which expose Canadian women to a huge amount of information that links health to weight. Using feminist poststructuralist and postcolonial lenses, this paper investigates young Lebanese-Canadian women's constructions of the body and "health" practices within the context of the dominant obesity discourse. Participant-centered conversations were held with 20 young Christian Lebanese-Canadian women. A thematic analysis was first conducted and was followed by a poststructuralist discourse analysis to further our understanding of how the participants construct themselves as subjects within various discourses surrounding health, obesity, and the body. Our findings reveal that most participants conflate the "healthy" body and the "ideal" body, both of which they ultimately portray as thin. The young women construct the "healthy"/"ideal" body as a solely individual responsibility, thus reinforcing the idea of "docile bodies." The majority of participants report their frequent involvement in disciplinary practices such as rigorous physical activity and dietary restrictions, and a few young women mention the use of other extreme forms of bodily monitoring such as detoxes, dieting pills, and compulsive exercise. We discuss the language employed by participants to construct their multiple and shifting subjectivities. For instance, many of these Lebanese-Canadian women use the term "us" to dissociate themselves from Lebanese women ("them"), whom they portray as overly focused on thinness and beauty and engaged in physical activity and other bodily practices for "superficial" purposes. The participants also use the "us/them" trope to distance themselves from "Canadian" women (read: white Euro-Canadian women), whom they portray as very physically active for purposes beyond the improvement of the physical appearance of the body. We discuss the impacts of the young Christian Lebanese-Canadian women

    Full Text Available About 40, ground plus one (G+1 residential units were designed using a hybrid structural framing system (RC frame and load bearing walls. A few months after the completion of the ground floor of the residential units, cracks appeared at several locations in the structure. Field and Laboratory testing was conducted to ascertain the in situ strength of concrete and steel reinforcement. The results of the experimental work were used in the analytical ETABS model for the structural stability calculations. The results indicated that residential units were marginally safe in the existing condition (completed ground floor, but the anticipated construction of the floor above the ground floor (G+1 could not be carried out as the strength of the structural system was inadequate. To increase the safety of existing ground floor and to provide the option of the construction of one floor above, rehabilitation and strengthening design was performed. The proposed strengthening design made use of welded wire fabric (WWF and carbon fibre reinforced polymer (CFRP laminates/sheets for the strengthening of walls, columns and slabs. The residential units will be strengthened in the near future.

    Although the value of spiritual care in the care of older adults is supported by research, few studies have focused specifically on prayer in residential care settings. This ethnographic study with fifteen chaplains and administrators in eleven residential care homes involved analyses of walking interviews and research diaries. Findings revealed the spaces in which prayer happens and the forms it takes. The identities of chaplains-their own spiritual practices, religious beliefs, and positioning within the facility-shaped their dis/comfort with prayer and how they located prayer within public and private spaces. Where organizational leadership endorsed the legitimacy of chaplaincy services, prayer was more likely to be offered. Even in these circumstances, however, religious diversity and questions about secularism left chaplains ambivalent about the appropriateness of prayer. The results demonstrate the relevance of religion and spirituality to residential care, and illustrate how prayer functions as an opportunity for connection and understanding.

However, inappropriate construction waste management lead to various problems such as illegal dumping along the roadsides, demolition waste and disposal of construction at landfills that Malaysia is facing serious shortage of landfill space and recently the issue has become more serious throughout the country, which these have caused major government sources and environmental issue. Solid waste management is one of the environmental issues which always been a concerned to most governments. In urban areas, 46% of the population in the statistics that shows the world population has reached six billion. In 1997, generation of the municipal solid waste was about 0.49 billion tons around the globe with an estimated annual growth rate of 3.2-4.5% in develop nations and 2-3% in developing countries. The characteristics of solid waste generated were changed due to the rapid urbanization and industrialization.

    2010-01-01

    The objective of this study was to examine the reported practices of construction firms and the beliefs of firm managers/supervisors with respect to employing youth under age 18 and ensuring their safety. The participants in this study were firm representatives from 54, mostly small to medium sized, construction firms in North Carolina. Survey responses were analyzed for the entire sample and within strata of firm size (1-10, 11+ employees) using descriptive statistics. Percentages and 95% confidence intervals were calculated. Chi-square tests were used to test for statistical significance in differences between firm sizes. The findings suggest limits in the adequacy of safety training given to youth in construction, particularly in light of the minimal experience firms require of young hires, that managers' beliefs about the causes of young worker injury are largely focused on worker behaviors rather than on the presence of hazards, and that managers' compliance with child labor laws may be hampered by their lack of knowledge of these laws and an ambivalence toward their usefulness and enforcement. While larger studies are needed to confirm and advance these findings, when considered along with prior studies, they demonstrate the need to improve the safety of the construction environment for youth. The development of new educational interventions by health and safety professionals targeted at construction firms are supported, as are efforts by government regulators to increase enforcement and employer knowledge of the child labor laws.

    2013-01-01

    In the context of rapid urbanization and new construction in rural China, residential building energy consumption has the potential to increase with the expected increase in demand. A process-based hybrid life-cycle assessment model is used to quantify the life-cycle energy use for both urban and rural residential buildings in China and determine the energy use characteristics of each life cycle phase. An input–output model for the pre-use phases is based on 2007 Chinese economic benchmark data. A process-based life-cycle assessment model for estimating the operation and demolition phases uses historical energy-intensity data. Results show that operation energy in both urban and rural residential buildings is dominant and varies from 75% to 86% of life cycle energy respectively. Gaps in living standards as well as differences in building structure and materials result in a life-cycle energy intensity of urban residential buildings that is 20% higher than that of rural residential buildings. The life-cycle energy of urban residential buildings is most sensitive to the reduction of operational energy intensity excluding heating energy which depends on both the occupants' energy-saving behavior as well as the performance of the building itself. -- Highlights: •We developed a hybrid LCA model to quantify the life-cycle energy for urban and rural residential buildings in China. •Operation energy in urban and rural residential buildings is dominant, varying from 75% to 86% of life cycle energy respectively. •Compared with rural residential buildings, the life-cycle energy intensity of urban residential buildings is 20% higher. •The life-cycle energy of urban residential buildings is most sensitive to the reduction of daily activity energy

    Health systems are in the midst of a transformation that is being driven by a variety of forces. This has important implications for medical educators because clinical practice environments play a key role in learning and professional development, and evolving health systems are beginning to demand that providers have "systems-ready" knowledge, attitudes, and skills. Such implications provide a clear mandate for medical schools to modify their goals and prepare physicians to practice flexibly within teams and effectively contribute to the improvement of health care delivery. In this context, the concepts of value-added medical education, authentic student roles, and health systems science are emerging as increasingly important. In this Article, the authors use a lens informed by communities of practice theory to explore these three concepts, examining the implications that the communities of practice theory has in the constructive reframing of educational practices-particularly common student roles and experiences-and charting future directions for medical education that better align with the needs of the health care system. The authors apply several key features of the communities of practice theory to current experiential roles for students, then propose a new approach to students' clinical experiences-value-added clinical systems learning roles-that provides students with opportunities to make meaningful contributions to patient care while learning health systems science at the patient and population level. Finally, the authors discuss implications for professional role formation and anticipated challenges to the design and implementation of value-added clinical systems learning roles.

    Full Text Available Green residential buildings (GRBs are one of the effective practices of energy saving and emission reduction in the construction industry. However, many real estate developers in China are less willing to develop GRBs, because of the factors affecting green residential building development (GRBD. In order to promote the sustainable development of GRBs in China, this paper, based on the perspective of real estate developers, identifies the influential and critical factors affecting GRBD, using the method of social network analysis (SNA. Firstly, 14 factors affecting GRBD are determined from 64 preliminary factors of three main elements, and the framework is established. Secondly, the relationships between the 14 factors are analyzed by SNA. Finally, four critical factors for GRBD, which are on the local economy development level, development strategy and innovation orientation, developer’s acknowledgement and positioning for GRBD, and experience and ability for GRBD, are identified by the social network centrality test. The findings illustrate the key issues that affect the development of GRBs, and provide references for policy making by the government and strategy formulation by real estate developers.

    1992-05-01

    The air tightness of 24 new houses was measured on a regular basis over periods up to three years to evaluate the structures' air barrier systems and to study the possibility of air barrier degradation, as would be indicated by an increase in the measured leakage rate. Ten of the houses were built with the polyethylene air barrier system and 14 using an early version of the Airtight Drywall Approach (ADA). The 24 project houses were architecturally similar and of approximately equal size and general layout. The airtightness of the polyethylene air barrier houses was found to remain stable over their respective monitoring periods. It was concluded that no evidence could be found to indicate polyethylene is unsuited for use as an air barrier material in residential construction. Although 2 of the 10 houses demonstrated possible, albeit slight, evidence of airtightness degradation, the magnitude of these changes was small and judged not to be of practical significance. All but one of the polyethylene houses met the airtightness requirements of the R-2000 program at the end of their monitoring periods. The project houses with the lowest measured leakage rates were those built with the double wall system and polyethylene barriers. The study also found that the airtightness of the 14 ADA houses remained stable during the monitoring period and it was concluded that no evidence could be found to indicate that the ADA system is unsuited for use in residential construction. Although 6 of the 15 houses displayed possible, but also slight, evidence of airtightness degradation, the magnitude of the changes was small and not of practical significance. All 14 houses met the airtightness requirements of the R-2000 program at the end of their respective monitoring periods. 19 refs., 191 figs., 39 tabs.

    The basic objective of this research effort was to perform a comparative analysis of the Quality Assurance practices related to the structural concrete phase on nine nuclear power plant projects which are (or have been) under construction in the United States in the past ten years. This analysis identified the response of each Quality Assurance program to the applicable criteria of 10 CFR Part 50, Appendix B as well as to the pertinent regulatory requirements and industry standards. The major emphasis was placed on the construction aspects of the structural concrete phase of each project. The engineering and design aspects were examined whenever they interfaced with the construction aspects. For those aspects of the Quality Assurance system which can be considered managerial in nature (i.e., organizational relationships, types of Quality Assurance programs, corrective action procedures, etc.) an attempt has been made to present the alternative approaches that were identified. For those aspects of the Quality Assurance system which are technical in nature (i.e., the frequency of testing for slump, compressive strength, etc.) an attempt has been made to present a comparative analysis between projects and in relation to the recommended or mandated practices presented in the appropriate industry codes and standards.

    1993-02-01

    The study measured the indoor radon concentration in the dwellings of 3074 persons, selected randomly from the central population register of Finland. Alpha track detectors and two consecutive half year measuring periods were used. The national mean of indoor radon concentration for persons living in low-rise residential buildings as well as blocks of flats was 145 and 82 Bq/m 3 , respectively. The mean for the total population was 123 Bq/m 3 . Based on the decision of the Ministry of Social Affairs and Health in 1992, the indoor radon concentration should not exceed 400 Bq/m 3 in already existing houses, the target for new construction being less than 200 Bq/m 3 . According to the study, the percentage of the Finnish population living in houses with an indoor radon concentration exceeding 200, 400 and 800 Bq/m 3 was 12.3 %, 3.6 % and 1.0 %

    Most of the existing office- and administration buildings in Germany were built between 1950 and 1980. During those years numbers of construction activities highly increased. Many of those buildings today have reached the end of their useful life expectancy. Especially components such as cladding materials and building services are spent. In addition, requirements on fire protection, utilisation, construction physics, energy technologies and the construction have changed. New ideas on working environments, tendencies to prefer teamwork and new communication technologies need to be considered. Fundamental renovation and revitalisation allows for revaluation of old buildings up to the standard of a new building. This is an economic and non-polluting solution that spares our natural resources. Even though we have great knowledge on conservation of historic buildings hardly any concepts on renovation of old office buildings have been generally accepted due to lack of experience. PROsab is a scientific research project sponsored by the German Federal Environmental Foundation (DBU). 15 typical office buildings built between 1950 and 1980 are going to be analysed. A detailed building analysis shall help, to develop solutions as well as concepts for renovation. Guideline is a feasibility study as those concepts will be realised in a future project. Primary goal of the concept should be the revaluation of old buildings up to the standard of a new building under architectural, technical and economical aspects. Present structures shall be used in a sensible manner. - Revaluating the architectural appearance. - Increasing useful area and optimising the amount of space. - Improving indoor environment and increasing workplace quality. - Decreasing energy consumptions and lowering operating expenses. Final results of the project will be compiled in a detailed catalogue of renovation. In addition to consisting handbooks and directives it will recommend practical procedures and

    Full Text Available This paper reviews the literature on commercial property index construction methodology. Alongside this, index construction methodology employed by various organizations in producing existing commercial property indices is also discussed. The aim of the review is to identify the best possible methodology option to adopt in developing Kuala Lumpur Office Price Index (KL - OPI. Among the Asean countries, Singapore is the only country in this region that produces retail and office price index. In the case of Malaysia, this is the first study of this nature in the country, which outcome would be useful indicator for the industry. Having reviewed the existing methodologies of commercial property indices, it is best to model KL-OPI by adopting the hedonic price method

    Full Text Available In modern society technical skills and competence are highly valued. The process of technologisation affects changes in language because the development of language is closely related to changes in society. Language becomes technical since humans constantly expose themselves to technical realia and their denominations. Yet, not always the widespread terms denoting technical concepts are grammatically acceptable. The main objectives of this article are the following: to analyse certain ad hoc selected terms used in the field of construction by use of questionnaires; to discuss the causes of ungrammatical use of the terms; to estimate the predominant role of linguistic or extralinguistic factors; to test and compare the degree of grammatically correct use of the terms by IV year students and employees of the construction sector.

    2011-11-01

    The aim of the present study was to present the process used to develop a composite model of situational leadership enacted within a person-centred nursing framework in residential care. Transforming the culture of the residential unit from a restrictive institution to a vibrant community of older adults requires transformational leadership. Situational leadership is one form of transformational leadership, which claims that there is not one leadership style that works in all situations. A model of situational leadership in residential care was developed through a series of systematic steps that identified direct linkages between situational leadership and the main constructs of the Person-Centred Nursing Framework. The process included reviewing the evidence, undertaking a comparative analysis, identifying key concepts, connecting the concepts and developing a model. A conceptual model is presented which integrates person-centredness with leadership thinking in order to effectively impact on the follower's performance in managing the care environment and delivering person-centred care. Currently the model is being utilized in an action research study to evaluate the role of leaders in the practice setting of long-term care. While some of the connecting concepts have been identified in the present study, more work needs to be done to unravel these connections in further study of leaders in practice. © 2011 Blackwell Publishing Ltd.

    Science.gov (United States)

    Reese, Leslie; Arauz, Rebeca Mejía; Bazán, Antonio Ray

    2012-01-01

    This article examines the relationships among the literacy practices engaged in by first-grade children and parents at home and the ways in which these practices are communicated, shaped, and fostered by teachers and administrators in two different sociocultural environments in urban Mexico. The differences observed between the home literacy experiences of children in a working class and a middle class community included transgenerational communication of assumptions regarding literacy and schooling, as well as attitudes associated with the parents' own school experiences. Class-based expectations on the part of teachers not only shaped interactions with parents, but were also reflected in the way the national curriculum was delivered, with a greater emphasis on rote skills and traditional reading instruction in the working class community. The authors argue that the school plays a role in the co-production of cultural capital in the home through its shaping of some of the literacy practices that children and families undertake.

    Full Text Available Research paradigms are only starting to emerge in relation to art and design practice. Consequently, research design in this domain often employs perspectives and methods developed in other disciplines. This paper traces the development of a proposal that combines theories from cognitive linguistics with graphic design practice. It describes the resulting challenges to and transformations of my long-held assumptions and understanding about graphic design and the communication process. It also outlines the way in which semantic analysis (a method from cognitive linguistics will be used in conjunction with different forms of visualisation--with visualisation used as a method to generate data for analysis as well as to present findings. Finally, it argues for an engagement by designers with conceptual metaphor theory and conceptual blending theory, as a way to facilitate reflection on design practice.

    Epidemiology is one of main courses for undergraduate students majoring in preventive medicine. There are some limitations in the traditional epidemiology teaching, which is usually characterized in indoctrinated education: "lectured by the teachers and listened by the students." In Zhejiang University, staff of the epidemiology division tried to explore a new teaching mode as 'student-centered, teacher-leading, question-based, and combining with literature discussion and course practice.' After practicing for two years, students were inspired in learning initiatives, with teaching effectiveness obviously improved.

    Full Text Available This research intends to answer the following main question: which traces of teacher autonomy construction are possible to achieve during reflective formative processes in disciplines like Methodology and Physics Teaching Practice carried out during three semesters, in an undergraduate program designed to physics teachers´ initial education? Using an analytical device based on teachers education research assumptions, which we called convergent formative triangulation for progressive teaching autonomy, we had as a main objective the search for the chance to achieve progressive levels of teachers autonomy, according to its three teacher professionalization models, present in a critical and transformative perspective, relating them to the current formative paradigms: the contents based one, the humanist, the activist, the reflective and the technical (approaches we called CHART. Taking into consideration future physics teachers´ collective reflections about their own teaching practice, this research was supported by the following methodological instruments: focus group, coaching, self-confrontation and formative assessment, taking the discourse analysis as background. The outcomes of this research, which followed a sample of 40 future High School physics teachers during three semesters, through the use of five formative steps (planning, implementation, reflection, socialization, involvement and continuity, revealed the evidences of teachers autonomy construction, probably provided by their own teaching practice collective reflections, according to the analytical device used. This research showed that the reflections brakes provided during the process can allow the future teachers to position themselves critically in relation to their future pedagogical activities, even after their initial training. This experience leads us to rethink how subjects like Methodology and Teaching Practice have been teaching in the teachers’ education programs at

  16. Reconceptualizing 'extremism' and 'moderation': from categories of analysis to categories of practice in the construction of collective identity.

    Hopkins, Nick; Kahani-Hopkins, Vered

    2009-03-01

    Much psychological research employs the categories of extremism and moderation as categories of analysis (e.g. to identify the psychological bases for, and consequences of, holding certain positions). This paper argues these categorizations inevitably reflect one's values and taken-for-granted assumptions about social reality and that their use as analytic categories limits our ability to explore what is really important: social actors' own constructions of social reality. In turn we argue that if we are to focus on this latter, there may be merit in exploring how social actors themselves use the categories of moderation and extremism to construct their own terms of reference. That is we propose to re-conceptualize the categories of moderation and extremism as categories of practice rather than analysis. The utility of this approach is illustrated with qualitative data. We argue that these data illustrate the importance of respecting social actors' own constructions of social reality (rather than imposing our own). Moreover, we argue that categories of moderation and extremism may be employed by social actors in diverse ways to construct different terms of reference and so recruit support for different identity-related projects.

    Full Text Available Phage display technology is undoubtedly a powerful tool for affinity selection of target-specific peptide. Commercially available premade phage libraries allow us to take screening in the easiest way. On the other hand, construction of a custom phage library seems to be inaccessible, because several practical tips are absent in instructions. This paper focuses on what should be born in mind for beginners using commercially available cloning kits (Ph.D. with type 3 vector and T7Select systems for M13 and T7 phage, respectively. In the M13 system, Pro or a basic amino acid (especially, Arg should be avoided at the N-terminus of peptide fused to gp3. In both systems, peptides containing odd number(s of Cys should be designed with caution. Also, DNA sequencing of a constructed library before biopanning is highly recommended for finding unexpected bias.

  8. The Influence of Trust on Project Management Practice within the Construction Industry

    Directory of Open Access Journals (Sweden)

    Scott Strahorn

    2017-03-01

    Full Text Available Given that any construction project is inherently a human endeavour, it follows that issues of trust are significant in terms of the stakeholder interactions that deliver eventual project outcomes.  Previous research indicates that the relational basis upon which projects are undertaken are intended to influence the likelihood of trusting relationships between stakeholders.  Thus, experiences of trust in a construction project environment are likely to be influenced by the contextual specifics of respective transactional and relational contracting (RC procurement mechanisms, given the divergent theoretical principles upon which they are founded.  The influence of trust has therefore been examined through the lived experiences of construction practitioners.  A phenomenological interview study consisting of thirty-five (35 participants was conducted with sensitivity to the procurement of experiences being recounted. Issues of trust were shown to be integral to stakeholder experiences in both procurement environments, with the benefits of trust acknowledged in many instances.  However, little understanding was evident regarding methods for building and maintaining trust, nor for repairing trust when problems arose. Importantly, despite the differing principles that underpin transactional and relational procurement, and particularly the contention that relational procurement would increase trust between trading partners, this was not evident; with individual personalities and appropriate risk apportionment shown to be greater influences upon the likelihood of trusting relationships.  It is reasonable to conjecture that relational contracts actually diminish the need for trust, given that the objective is to reduce uncertainty through formulaic approaches to risk distribution and reward; the absence of risk negates the need for trust.  Ultimately, the potential to deliver improved project outcomes as a result of proactive approaches to

    Fiaveh, Daniel Y; Izugbara, Chimaraoke O; Okyerefo, Michael P K; Reysoo, Fenneke; Fayorsey, Clara K

    2015-01-01

    Using qualitative data gathered through in-depth interviews with women in Accra, Ghana, this paper explores narratives of masculinity and femininity and sexual risk negotiation practices among women. While women framed 'proper' masculinity in terms of stereotypical reproductive norms, they also acknowledged the fluidity and multiplicity of masculinities. Femininity was more uniformly characterised in terms of physical attractiveness and beauty, responsibility and reproduction. These features, especially those related to adherence to morally and socially appropriate sexual norms (e.g., menstrual and bodily hygiene, unplanned pregnancy etc.), influenced women's approach to sexual negotiation. Work aiming to support women to negotiate sex safely needs to pay attention to their notions of gender and practices of sexual negotiation.

    2010-03-01

    This is a qualitative descriptive research, carried out with nursing undergraduates from Rio de Janeiro State University, Brazil. The purpose is to discuss students' experiences and their social practice in assisting drugs uses. Data were collected from December 2008 to January, 2009, with the use of focal groups composed by 19 undergraduates from the last three semesters of the course. The project was approved by the Ethics Research Commission. All participants signed the Informed Consent. The results evidenced students' difficulty in facing reality, due to the contrast between theory and practice. Such difficulty came out as a consequence of an inapropriate educational approach. We concluded that the academic institutions should optimize the use of teaching process. Professional formation related to the phenomenon of drug abuse is considered essential as it becomes more and more frequent in nurses' daily routines.

  13. SOLAR SYSTEMS FOR RESIDENTIAL BUILDINGS IN ACCORDANCE WITH OPERATING CONDITIONS OF THE REPUBLIC OF BELARUS

    Directory of Open Access Journals (Sweden)

    M. A. Rutkowski

    2017-01-01

    Full Text Available Solar systems are actively applied for heat supply of buildings in Europe. Usage of solar energy for heat supply of residential buildings is considered as rather efficient for the Republic of Belarus because total amount of direct and scattered solar radiation entering horizontal surface is equivalent to an average European index for the climate of Belarus. The paper analyzes an existing dependence on determination of solar system efficiency and proposes an amended formula for calculations while designing solar consumption systems and its legitimacy has been experimentally proved. A scheme of an experimental unit with explanations and a brief description for execution of experiments and main results of the completed investigations have been presented in the paper. Experiments have been carried out for solar systems with natural and forced coolant circulation. Attention has been paid to obtaining maximum possible temperature potential of the coolant during operation of the solar system within periods of high and low solar radiation intensity. Recommendations on practical application of solar systems for multi-storey residential buildings houses and mansion-type houses have been given in the paper. The paper presents technological principles of constructing “passive” solar heating devices. A comparison of traditionally applied and proposed alternative solar systems has been made for operational conditions in Belarus. The paper proposes a solar system for hot water supply of multi-storey buildings. The proposed system has found its first realization in the Republic while designing and constructing an energy-efficient demonstration 10-storey residential building in Mogilev within the framework of the UN Development Program project and Global Environment Fund “Improvement of energy efficiency for residential buildings in the Republic of Belarus”

  14. Penalising Model Component Complexity: A Principled, Practical Approach to Constructing Priors

    KAUST Repository

    Simpson, Daniel

    2017-04-06

    In this paper, we introduce a new concept for constructing prior distributions. We exploit the natural nested structure inherent to many model components, which defines the model component to be a flexible extension of a base model. Proper priors are defined to penalise the complexity induced by deviating from the simpler base model and are formulated after the input of a user-defined scaling parameter for that model component, both in the univariate and the multivariate case. These priors are invariant to repa-rameterisations, have a natural connection to Jeffreys\\' priors, are designed to support Occam\\'s razor and seem to have excellent robustness properties, all which are highly desirable and allow us to use this approach to define default prior distributions. Through examples and theoretical results, we demonstrate the appropriateness of this approach and how it can be applied in various situations.

Through examples and theoretical results, we demonstrate the appropriateness of this approach and how it can be applied in various situations.

    This study evaluates and contrasts the management practice and the performance that characterise Environmental Impact Assessments (EIA) in Italy and in the UK. The methodology relies on the investigation of six carefully selected case studies, critically reviewed by referring to EIA and project design information, as well as collecting the opinion of key project participants. The study focuses on the construction industry and on specific key sectors like infrastructure for transport and renewable energy and commercial and tourism development. A main term of reference for the analyses has been established by critically reviewing international literature so as to outline common good practice, requirements for the enhancement of sustainability principles and typically incurred drawbacks. The proposed approach enhances transfer of knowledge and of experiences between the analyzed contexts and allows the provision of guidelines for practitioners. Distinctive differences between the UK and the Italian EIA systems have been detected for pivotal phases and elements of EIA, like screening, scoping, analysis of alternatives and of potential impacts, definition of mitigation strategies, review, decision making, public participation and follow up. - Highlights: ► The Italian and the UK Environmental Impact Assessment systems are compared. ► The research is centred on the construction industry. ► Issues and shortcomings are analysed by investigating six case studies. ► Integration of EIA with sustainability principles is appraised. ► General guidelines are provided to assist practitioners in the two national contexts.

    From the survey responses and the policy analysis, the initial findings on this paper present some aspects of knowledge, attitude and practice (KAP) on disability which are presented as following: Firstly, there is a significant changes in legal documents and social policies related to disability in Vietnam, especially from 2006, in terms of its name and contents for improving the life of PWD with inclusive approach, however the meaning of disability is not clear in policies. Secondly, the understanding on disability is mainly based on medical/individual model which focuses on the disability's causes in words of health or individual problem rather than viewing the social causes in aspects of the social barriers and restriction, in addition almost policies focus on the problems of PWD rather than the social aspects. Thirdly, social attitude toward disability and PWD seems to be very empathetic, however it is less regard to CWD's ability as well as there are more attitudes on charity giving and supporting than helping them to be independent in their life. Finally, in spite of positive knowledge and attitudes on disability, there is still limitation on practical activities towards CWD/PWD from society in daily life.

    2015-01-01

    This paper presents validated building shielding factors designed for contemporary US housing-stock under an idealized, yet realistic, exposure scenario from contaminant deposition on the roof and surrounding surfaces. The building shielding factors are intended for use in emergency planning and level three probabilistic risk assessments for a variety of postulated radiological events in which a realistic assessment is necessary to better understand the potential risks for accident mitigation and emergency response planning. Factors are calculated from detailed computational housing-units models using the general-purpose Monte Carlo N-Particle computational code, MCNP5, and are benchmarked from a series of narrow- and broad-beam measurements analyzing the shielding effectiveness of ten common general-purpose construction materials and ten shielding models representing the primary weather barriers (walls and roofs) of likely US housing-stock. Each model was designed to scale based on common residential construction practices and include, to the extent practical, all structurally significant components important for shielding against ionizing radiation. Calculations were performed for floor-specific locations from contaminant deposition on the roof and surrounding ground as well as for computing a weighted-average representative building shielding factor for single- and multi-story detached homes, both with and without basement as well for single-wide manufactured housing-unit.

  6. Guidelines for residential commissioning

    Energy Technology Data Exchange (ETDEWEB)

    Wray, Craig P.; Walker, Iain S.; Sherman, Max H.

    2003-01-31

    Currently, houses do not perform optimally or even as many codes and forecasts predict, largely because they are field assembled and there is no consistent process to identify problems or to correct them. Residential commissioning is a solution to this problem. This guide is the culmination of a 30-month project that began in September 1999. The ultimate objective of the project is to increase the number of houses that undergo commissioning, which will improve the quality, comfort, and safety of homes for California citizens. The project goal is to lay the groundwork for a residential commissioning industry in California focused on end-use energy and non-energy issues. As such, we intend this guide to be a beginning and not an end. Our intent is that the guide will lead to the programmatic integration of commissioning with other building industry processes, which in turn will provide more value to a single site visit for people such as home energy auditors and raters, home inspectors, and building performance contractors. Project work to support the development of this guide includes: a literature review and annotated bibliography, which facilitates access to 469 documents related to residential commissioning published over the past 20 years (Wray et al. 2000), an analysis of the potential benefits one can realistically expect from commissioning new and existing California houses (Matson et al. 2002), and an assessment of 107 diagnostic tools for evaluating residential commissioning metrics (Wray et al. 2002). In this guide, we describe the issues that non-experts should consider in developing a commissioning program to achieve the benefits we have identified. We do this by providing specific recommendations about: how to structure the commissioning process, which diagnostics to use, and how to use them to commission new and existing houses. Using examples, we also demonstrate the potential benefits of applying the recommended whole-house commissioning approach to

  9. Guidelines for target costing adoption in the development of products for the residential real estate market

    Directory of Open Access Journals (Sweden)

    Reymard Savio Sampaio de Melo

    Full Text Available Abstract This study focuses on the problems associated with the traditional practice of reducing costs in construction and the need to increase business competitiveness in the residential real estate sector. In this context, target costing is a promising approach to improve the competitiveness of companies by ensuring that the products launched on the market do not jeopardize the company's results and value delivery to customers. However, far too little attention is paid to target costing implementation by companies that develop residential real state products for sale and face strong market competition. Thus, this paper seeks to investigate whether the standard framework of target costing in the literature applies - with or without adjustments - to real estate developers. Case study was the research strategy adopted. Guidelines are proposed for the introduction of target costing in the development process of residential real estate products. The proposed guidelines are related to the three main sections of the target costing process: market-driven costing, product-level target costing and component-level target costing.

  10. An interactional ethnographic study of the construction of literate practices of science and writing in a university science classroom

    Sena, Nuno Afonso De Freitas Lopes De

    An interactional ethnographic study informed by a sociocultural perspective was conducted to examine how a professor and students discursively and interactionally shaped the basis for engaging in the work of a community of geologists. Specifically, the study examined the role the Question of the Day, an interactive writing activity in the lecture, in affording students opportunities for learning the literate practices of science and how to incorporate them in thinking critically. A writing-intensive, introductory oceanography course given in the Geological Sciences Department was chosen because the professor designed it to emphasize writing in the discipline and science literacy within a science inquiry framework. The study was conducted in two phases: a pilot in 2002 and the current study in the Spring Quarter of 2003. Grounded in the view that members in a classroom construct a culture, this study explored the daily construction of the literate practices of science and writing. This view of classrooms was informed by four bodies of research: interactional ethnography, sociolinguistics sociology of science and Writing In the Disciplines. Through participant observation, data were collected in the lecture and laboratory settings in the form of field notes, video, interviews, and artifacts to explore issues of science literacy in discourse, social action, and writing. Examination of participation in the Question of the Day interactive writing activity revealed that it played a key role in initiating and supporting a view of science and inquiry. As the activity permitted collaboration, it encouraged students to engage in the social process to critically explore a discourse of science and key practices with and through their writing. In daily interaction, participants were shown to take up social positions as scientist and engage in science inquiry to explore theory, examine data, and articulately reformulate knowledge in making oral and written scientific arguments

    Effective female education on cervical cancer prevention has been shown to increase awareness and uptake of screening. However, sustaining increase in uptake poses a challenge to control efforts. Peer health education has been used as an effective tool for ensuring sustained behavior change. This study was undertaken to assess the effectiveness of peer health education on perception, willingness to screen and uptake of cervical cancer screening by women. A before and after intervention study was undertaken in 2 urban cities in Enugu state, Nigeria among women of reproductive age attending women's meeting in Anglican churches. Multistage sampling was used to select 300 women. Peer health education was provided once monthly for 3 consecutive sessions over a period of 3 months. Data was collected at baseline and after the intervention using pre-tested questionnaires. Descriptive statistics and tests of significance of observed differences and associations were done at p-value of education, employment status and parity (p education is an effective strategy for increasing women's perception of benefits of early detection of cervical cancer through screening. It is also effective for increasing their practice of screening for cervical cancer.

  12. Women's collective constructions of embodied practices through memory work: Cartesian dualism in memories of sweating and pain.

    2004-03-01

    The research presented in this paper uses memory work as a method to explore six women's collective constructions of two embodied practices, sweating and pain. The paper identifies limitations in the ways in which social constructionist research has theorized the relationship between discourse and materiality, and it proposes an approach to the study of embodiment which enjoins, rather than bridges, the discursive and the non-discursive. The paper presents an analysis of 25 memories of sweating and pain which suggests that Cartesian dualism is central to the women's accounts of their experiences. However, such dualism does not operate as a stable organizing principle. Rather, it offers two strategies for the performance of a split between mind and body. The paper traces the ways in which dualism can be both functional and restrictive, and explores the tensions between these two forms. The paper concludes by identifiying opportunities and limitations associated with memory work as a method for studying embodiment.

    2015-12-01

    This article presents information about the construct validity and reliability of a new teacher self-report measure of classroom instructional and behavioral practices (the Classroom Strategies Scales-Teacher Form; CSS-T). The theoretical underpinnings and empirical basis for the instructional and behavioral management scales are presented. Information is provided about the construct validity, internal consistency, test-retest reliability, and freedom from item-bias of the scales. Given previous investigations with the CSS Observer Form, it was hypothesized that internal consistency would be adequate and that confirmatory factor analyses (CFA) of CSS-T data from 293 classrooms would offer empirical support for the CSS-T's Total, Composite and subscales, and yield a similar factor structure to that of the CSS Observer Form. Goodness-of-fit indices of χ2/df, Root Mean Square Error of Approximation, Goodness of Fit Index, and Adjusted Goodness of Fit Index suggested satisfactory fit of proposed CFA models whereas the Comparative Fit Index did not. Internal consistency estimates of .93 and .94 were obtained for the Instructional Strategies and Behavioral Strategies Total scales respectively. Adequate test-retest reliability was found for instructional and behavioral total scales (r = .79, r = .84, percent agreement 93% and 93%). The CSS-T evidences freedom from item bias on important teacher demographics (age, educational degree, and years of teaching experience). Implications of results are discussed.

  15. ASHRAE and residential ventilation

    Energy Technology Data Exchange (ETDEWEB)

    Sherman, Max H.

    2003-10-01

    In the last quarter of a century, the western world has become increasingly aware of environmental threats to health and safety. During this period, people psychologically retreated away from outdoors hazards such as pesticides, smog, lead, oil spills, and dioxin to the seeming security of their homes. However, the indoor environment may not be healthier than the outdoor environment, as has become more apparent over the past few years with issues such as mold, formaldehyde, and sick-building syndrome. While the built human environment has changed substantially over the past 10,000 years, human biology has not; poor indoor air quality creates health risks and can be uncomfortable. The human race has found, over time, that it is essential to manage the indoor environments of their homes. ASHRAE has long been in the business of ventilation, but most of the focus of that effort has been in the area of commercial and institutional buildings. Residential ventilation was traditionally not a major concern because it was felt that, between operable windows and envelope leakage, people were getting enough outside air in their homes. In the quarter of a century since the first oil shock, houses have gotten much more energy efficient. At the same time, the kinds of materials and functions in houses changed in character in response to people's needs. People became more environmentally conscious and aware not only about the resources they were consuming but about the environment in which they lived. All of these factors contributed to an increasing level of public concern about residential indoor air quality and ventilation. Where once there was an easy feeling about the residential indoor environment, there is now a desire to define levels of acceptability and performance. Many institutions--both public and private--have interests in Indoor Air Quality (IAQ), but ASHRAE, as the professional society that has had ventilation as part of its mission for over 100 years, is the

    2017-12-01

    Full Text Available Energy consumed the in urban sector accounts for a large proportion of total world delivered energy consumption. Residential building energy consumption is an important part of urban energy consumption. However, there are few studies focused on this issue and that have simulated the energy consumption of residential buildings using questionnaire data. In this research, an eQUEST study was conducted for different residential buildings in the Olympic Central Area in Beijing. Real-time meteorological observation data and an actual energy consumption schedule generated by questionnaire data were used to improve the eQUEST model in the absence of actual energy consumption data. The simulated total energy consumption of residential buildings in the case area in 2015 is 21,262.28 tce, and the average annual energy consumption per unit area is 20.09 kgce/(m2·a. Space heating accounted for 45% of the total energy consumption as the highest proportion, and the second highest was household appliances, which accounted for 20%. The results showed that old residential buildings, multi-storey buildings and large-sized apartment buildings consume more energy. The internal units, building height, per capita construction area, the number of occupants and length of power use had significant impact on residential energy consumption. The result of this study will provide practical reference for energy saving reconstruction of residential buildings in Beijing.

  19. Mitigating construction safety risks using prevention through design.

    Gangolells, Marta; Casals, Miquel; Forcada, Núria; Roca, Xavier; Fuertes, Alba

    2010-04-01

    Research and practice have demonstrated that decisions made prior to work at construction sites can influence construction worker safety. However, it has also been argued that most architects and design engineers possess neither the knowledge of construction safety nor the knowledge of construction processes necessary to effectively perform Construction Hazards Prevention through Design (CHPtD). This paper introduces a quantitative methodology that supports designers by providing a way to evaluate the safety-related performance of residential construction designs using a risk analysis-based approach. The methodology compares the overall safety risk level of various construction designs and ranks the significance of the various safety risks of each of these designs. The methodology also compares the absolute importance of a particular safety risk in various construction designs. Because the methodology identifies the relevance of each safety risk at a particular site prior to the construction stage, significant risks are highlighted in advance. Thus, a range of measures for mitigating safety risks can then be implemented during on-site construction. The methodology is specially worthwhile for designers, who can compare construction techniques and systems during the design phase and determine the corresponding level of safety risk without their creative talents being restricted. By using this methodology, construction companies can improve their on-site safety performance. Copyright 2010 Elsevier Ltd. All rights reserved.

    The increase in life expectancy enhances phenomena such as second couplehood in old age following widowhood or divorce as an alternative way of coping with changes that occur with aging. Research on the phenomenon has focused mainly on individual and dyadic perspectives of the repartnered. The aim of this article was to explore repartnering from the stepfamily's perspective, which has scarcely been studied. Nineteen Israeli stepfamilies (38 multigenerational families) were recruited using criterion sampling, of men who repartnered at age 65+ and women at 60+, with children and grandchildren from a lifelong marriage that ended in widowhood or divorce. We audio-recorded and transcribed verbatim 107 semi-structured, qualitative interviews with older partners, their adult children, and grandchildren. Analysis was based on grounded theory and dyadic analysis principles adapted to families. It showed how repartnering in old age changed the family structure, constructing complex stepfamilies, which require further study. Emotional experiences refer to repartnering being a replacement for couplehood but not for parenthood/grandparenthood. Practical consequences refer to "knowing their place" within the stepfamily and included the following subthemes: showing affection; participating in memorials for the deceased spouse; sharing, listening, and assisting. Findings are discussed regarding life course and family life cycle perspectives. Copyright © 2014 Elsevier Inc. All rights reserved.

    Residential building energy use is an important contributor to greenhouse gas emissions and in the United States represents about 20% of total energy consumption. A number of previous macro-scale studies of residential energy consumption and energy-efficiency improvements are mainly concerned with national or international aggregate potential savings. In this paper we look into the details of how a collection of specific homes in one region might reduce energy consumption and carbon emissions, with particular attention given to some practical limits to what can be achieved by upgrading the existing residential building stock. Using a simple model of residential, single-family home construction characteristics, estimates are made for the efficacy of (i) changes to behavioral patterns that do not involve building shell modifications; (ii) straightforward air-infiltration mitigation measures, and (iii) insulation measures. We derive estimates of net lifetime savings resulting from these measures, in terms of energy, carbon emissions and dollars. This study points out explicitly the importance of local and regional patterns in decision-making about what fraction of necessary regional or national emissions reduction might be accomplished through energy-efficiency measures and how much might need to concentrate more heavily on renewable or other carbon-free sources of energy. - Highlights: → Macro-scale estimates of building energy efficiency measures are not adequate for implementing policy decisions. → Measures taken to implement building energy efficiency upgrades will likely encounter practical limits given the existing building stock. → Energy efficiency measures combined with increases in renewable energy use will be necessary for climate change mitigation. → Regional and local variations in building energy use must be taken into account in energy and climate policy.

    2005-08-04

    The primary purpose of the project was to identify materials and methods that will make the envelope of a house flood damage resistant. Flood damage resistant materials and systems are intended to be used to repair houses subsequent to flooding. This project was also intended to develop methods of restoring the envelopes of houses that have been flooded but are repairable and may be subject to future flooding. Then if the house floods again, damage will not be as extensive as in previous flood events and restoration costs and efforts will be minimized. The purpose of the first pair of field tests was to establish a baseline for typical current residential construction practice. The first test modules used materials and systems that were commonly found in residential envelopes throughout the U.S. The purpose of the second pair of field tests was to begin evaluating potential residential envelope materials and systems that were projected to be more flood-damage resistant and restorable than the conventional materials and systems tested in the first pair of tests. The purpose of testing the third slab-on-grade module was to attempt to dry flood proof the module (no floodwater within the structure). If the module could be sealed well enough to prevent water from entering, then this would be an effective method of making the interior materials and systems flood damage resistant. The third crawl space module was tested in the same manner as the previous modules and provided an opportunity to do flood tests of additional residential materials and systems. Another purpose of the project was to develop the methodology to collect representative, measured, reproducible (i.e. scientific) data on how various residential materials and systems respond to flooding conditions so that future recommendations for repairing flood damaged houses could be based on scientific data. An additional benefit of collecting this data is that it will be used in the development of a standard test

    This data article relates to the research paper Energy consumption and efficiency technology measures in European non-residential buildings (D'Agostino et al., 2017) [1]. The reported data have been collected in the framework of the Green Building Programme that ran from 2006 to 2014. The project has encouraged the adoption of efficiency measures to boost energy savings in European non-residential buildings. Data focus on the one-thousand buildings that joined the Programme allowing to save around 985 GWh/year. The main requirement to join the Programme was the reduction of at least 25% primary energy consumption in a new or retrofitted building. Energy consumption before and after the renovation are provided for retrofitted buildings while, in new constructions, a building had to be designed using at least 25% less energy than requested by the country's building codes. The following data are linked within this article: energy consumption, absolute and relative savings related to primary energy, saving percentages, implemented efficiency measures and renewables. Further information is given about each building in relation to geometry, envelope, materials, lighting and systems.

    2006-09-15

    A survey of residential energy code requirements was discussed. New housing is approximately 13 per cent more efficient than housing built 15 years ago, and more stringent energy efficiency requirements in building codes have contributed to decreased energy use and greenhouse gas (GHG) emissions. However, a survey of residential energy codes across Canada has determined that explicit demands for energy efficiency are currently only present in British Columbia (BC), Manitoba, Ontario and Quebec. The survey evaluated more than 4300 single-detached homes built between 2000 and 2005 using data from the EnerGuide for Houses (EGH) database. House area, volume, airtightness and construction characteristics were reviewed to create archetypes for 8 geographic areas. The survey indicated that in Quebec and the Maritimes, 90 per cent of houses comply with ventilation system requirements of the National Building Code, while compliance in the rest of Canada is much lower. Heat recovery ventilation use is predominant in the Atlantic provinces. Direct-vent or condensing furnaces constitute the majority of installed systems in provinces where natural gas is the primary space heating fuel. Details of Insulation levels for walls, double-glazed windows, and building code insulation standards were also reviewed. It was concluded that if R-2000 levels of energy efficiency were applied, total average energy consumption would be reduced by 36 per cent in Canada. 2 tabs.

    This paper focuses on appropriation of natural capital through construction of buildings. The ecological footprint and the Costanza natural capital concepts are applied. The environmental consequences of human settlement are currently of great concern, and a need is felt to reduce the impact of building on the environment. The embodied energy of building materials and the "land area" required to sustain their production are considered to evaluate the demand on nature of this activity. The ecological footprints of 2 typical Italian buildings are compared. The paper also focuses on how to reduce the natural capital appropriation of building construction by means of environmentally inexpensive materials, renewable energy resources, and optimization of the use of bioproductive land by construction of multistoried buildings. Finally, to allocate an environmental load of buildings, an economic evaluation of natural capital appropriation through building construction is proposed.

    Full Text Available The Urban Residential has developed and changed in different periods of time with successive and gradual shifts, as it cast a shadow over the characterization of modern urbanism in Iraq. The semi-total absence of the governing legislation of urbanization as well as the weakness of the State's role of supervisory in addition to neglecting urban heritage contributed in offering a strange environment in relation to its traditional identity. That was increased by the pressure of the using urban environment as a result of the increasing of population as well as the growth of people’s needs. The research aims to provide an objective view for a mechanism of the application of urban legislation to monitor the implementation of the business relating to the urban structure in general and specifically the urban residential areas in order to preserve the traditional identity of the modern Iraqi city. For the purpose of treating the problem of research and to achieve its goals, the research supposes that the legislative system is based on a pyramid arrangement in its vocabulary, which is flexible in its application, and are drawn from objective reality, it can produce urban residential with local identity. The elements of the practical influential process of the legislative factor identified by the planning legislation, laws, regulations, controls and limitations, supervision and oversight. And then draw theoretical indicators which affect the urban environment, namely: proportionately, essence and appearance, construction and the sky line, the scale and size, bearings, cover-up, opening-up and containment through the study of a number of legislative irregularities in neighborhoods and residential areas that produced these indicators. For applying and testing these indicators practically, two selective neighborhoods in Al Rabeea'a District in Baghdad has been chosen and with a précised field survey the search findings are: the poverty of Urban elements

    Photovoltaics, heat pumps and fuel cells offer enormous potential for sustainable energy supply in residential buildings. Solar thermal energy and wood-fired boilers also play an important role in refurbishment. Due to the wide range of possible combinations, the wishes of building owners and homeowners for an ecologically and economically individually adapted energy concept can be fulfilled accurately. This book provides you with a holistic approach to the residential building and its supply of electricity, heat and water. All processes that play a role in the house's energy consumption are examined in their entirety for their potentials and potential savings. The author analyses and describes in detail the resources of buildings and their surroundings - and how they can be used for a truly independent supply. The focus is on reducing energy consumption and costs, the generation and supply of energy from renewable sources and energy storage - considered in new construction and modernisation. The supply of water is also dealt with if it touches on energy issues. The author draws attention to standards and regulations and gives practical advice for planning and installation. The focus is on the so-called sector coupling: electricity from the sun, wind and hydrogen is used to supply electrical consumers in the home, charging technology for electric vehicles, hot water and heating. The time of the boilers and combustion engines has elapsed. Clean electricity and digital controls - power and intelligence - determine the regenerative building technology. [de

    To make innovation and continuous improvement as a norm, some traditional practices must become unlearnt. Change for growth and competitiveness are required for sustainability for any profitable business such as the construction industry. The leading companies are willing to implement Total Quality Management (TQM) principles, to realise potential advantages and improve growth and efficiency. Ironically, researches recollected quality as the most significant provider for competitive advantage in industrial leadership. The two objectives of this paper are 1) Identify TQM effectiveness in residential projects and 2) Identify the client satisfaction/dissatisfaction areas using Analytical Hierarchy Process (AHP) and suggest effective mitigate measures. Using statistical survey techniques like set of questionnaire survey, it is observed that total quality management was applied in some leading successful organization to an extent. The main attributes for quality achievement can be defined as teamwork and better communication with single agreed goal between client and contractor. Onsite safety is a paramount attribute in the identifying quality within the residential projects. It was noticed that the process based quality methods such as onsite safe working condition; safe management system and modern engineering process safety controls etc. as interlinked functions. Training and effective communication with all stakeholders on quality management principles is essential for effective quality work. Late Only through effective TQM principles companies can avoid some contract litigations with an increased client satisfaction Index.

    Low-energy buildings can make a major contribution to general sustainable development by providing a solution to problems related to the use of fossil fuels. The EPBD (EU Directive on Energy Performance of Buildings) requirements that by 2020 new building shall be constructed to use nearly zero energy, and no fossil fuels, can be accomplished by combining low-energy buildings with renewable energy via low-temperature district heating in cities and suburbs, and via heat pumps for low-density settlements. Based on experience with passive houses, low-energy buildings meeting the energy performance requirements of 2020 are expected to cost only a few percent more than conventional buildings. The very large and rapid changes needed in the energy performance of buildings is a challenge for the building sector, but one that can be overcome by better methods of developing products and designing, constructing and operating buildings. Simulation-based analysis and optimisation, and considerations of durability, will be important here. Building may thus be transformed from an experience-based sector to one based on knowledge and research, with high-quality sustainable products and good business opportunities. (Author)

    As part of a remedial action program to decontaminate over 200 residential properties, 12 typical properties were selected and a demonstration program was initiated in the spring of 1985. The residences selected represented a range of contamination levels and configurations and differing architectural styles representative of the age of construction. The physical limitations of the sites and the overall nature of a decontamination project in active residential communities imposed a number of severe restrictions on work methods and equipment. Regulations governing transportation and disposal set virtually zero defect standards for the condition of containers. The intrusive nature of the work in residential neighborhoods required continual interaction with local residents, public officials and citizen task forces. Media coverage was very high. Numerous briefings were held to allay fears and promote public understanding. Numerous issues ranging in content from public health and safety to engineering and construction methods arose during the remedial action program. These issues were resolved by a multi-disciplined management team which was knowledgeable in public administration, radiation physics, and engineering design and construction. This paper discusses the nature of the problem, the methods applied to resolve the problem and the experience gained as a result of a remedial action program

    2017-06-01

    Full Text Available The present article is a position paper aiming to initiate a professional debate related to the aspects related to the urban dysfunctions leading to the wear of the residential areas. The paper proposes a definition of the wear process, identify the main causes leading to its occurrence and propose a number of solutions to neutralise the dysfunctions. The three wearing phases of residential areas components are emphasized, exploring their lifecycle. In order to perform the study of urban wear, the status of the residential areas components can be established and monitored, and also the variables of the function that can mathematically model the specific wear process may be considered. The paper is considered a first step for the model adjustment, to be tested and validated in the following steps. Based on the mathematical method and model, there can be created, in a potential future research, the possibility of determining the precarity degree for residential areas/neighbourhoods and cities, by minimising the subjective component of the analyses preceding the decision for renovation or regeneration.

  6. Citizen Science as a Tool for Conservation in Residential Ecosystems

    Directory of Open Access Journals (Sweden)

    Caren B. Cooper

    2007-12-01

    Full Text Available Human activities, such as mining, forestry, and agriculture, strongly influence processes in natural systems. Because conservation has focused on managing and protecting wildlands, research has focused on understanding the indirect influence of these human activities on wildlands. Although a conservation focus on wildlands is critically important, the concept of residential area as an ecosystem is relatively new, and little is known about the potential of such areas to contribute to the conservation of biodiversity. As urban sprawl increases, it becomes urgent to construct a method to research and improve the impacts of management strategies for residential landscapes. If the cumulative activities of individual property owners could help conserve biodiversity, then residential matrix management could become a critical piece of the conservation puzzle. "Citizen science" is a method of integrating public outreach and scientific data collection locally, regionally, and across large geographic scales. By involving citizen participants directly in monitoring and active management of residential lands, citizen science can generate powerful matrix management efforts, defying the "tyranny of small decisions" and leading to positive, cumulative, and measurable impacts on biodiversity.

    2016-03-01

    Full Text Available Precarity is becoming the paradigmatic description of young people’s work conditions in crisis-ridden Greece, but also in other European countries. Focusing on interview data on the work experiences of young adults (18-26 years old, in urban centres of Greece, this study attempts to explore the ways in which informants account for working in precarious conditions and construct agency and subjectivity within these ways of accounting. The analysis drawing on insights from critical discursive social psychology indicates that participants construct precarious work conditions as widespread and banal a by treating precarious work as a sine qua non condition of youth employment, b by considering precarious work as an inherent trait of the Greek job-market, c by considering precarious work as a necessary step on a (biographical path leading to the desired and/or appropriate job, or d by adopting a “there is no other alternative” accounting, representing precarious job conditions as the only alternative to unemployment. The analysis also points out the ways in which participants orient themselves to a dilemma of stake and accountability, being concerned to position themselves as effortful subjects, while they are rhetorically constructing the banal regime of precarious labour. The discussion considers the need to bring into the scope of social and political psychology the specific nuances of precarious labour.

    Full Text Available In the article, the author provides a systematic analysis and interpretation of Kant’s major work ‘Groundwork for the Metaphysics of Morals’. The author demonstrates that Kant viewed his programme of founding a new kind of metaphysics as a distinctive unity of the practical and theoretical part of philosophy, i.e. a unity of pure practical reason with speculative reason. It is already manifested in the original common assumption of the ‘Groundwork’, because ‘at the end there can only be one and the same reason that can be diff erent only in its application’.

  20. Integrated urban water management for residential areas: a reuse model.

    Science.gov (United States)

    Barton, A B; Argue, J R

    2009-01-01

    Global concern over growing urban water demand in the face of limited water resources has focussed attention on the need for better management of available water resources. This paper takes the "fit for purpose" concept and applies it in the development of a model aimed at changing current practices with respect to residential planning by integrating reuse systems into the design layout. This residential reuse model provides an approach to the design of residential developments seeking to maximise water reuse. Water balance modelling is used to assess the extent to which local water resources can satisfy residential demands with conditions based on the city of Adelaide, Australia. Physical conditions include a relatively flat topography and a temperate climate, with annual rainfall being around 500 mm. The level of water-self-sufficiency that may be achieved within a reuse development in this environment is estimated at around 60%. A case study is also presented in which a conventional development is re-designed on the basis of the reuse model. Costing of the two developments indicates the reuse scenario is only marginally more expensive. Such costings however do not include the benefit to upstream and downstream environments resulting from reduced demand and discharges. As governments look to developers to recover system augmentation and environmental costs the economics of such approaches will increase.

  1. The construction of ethnic differences in work incapacity risks: Analysing ordering practices of physicians in the Netherlands.

    Science.gov (United States)

    Meershoek, Agnes; Krumeich, Anja; Vos, Rein

    2011-01-01

    Drawing from Science and Technology Studies we investigate the consequences for social differentiation of physicians' practices in Dutch illness certification. Using participant observation methods, we followed six 'Arbodienst' physicians for two weeks each. Our analysis explores whether and how the work of Dutch physicians contributes to the appearance of a category of 'problematic migrant patients'. We present how physicians, in using instruments to distinguish plausible from implausible claims for sick leave, impose order upon reality. In particular situations this ordering involves a distinction between Dutch and migrant clients. Here ethnicity appears in physicians' practice as a separate instrument to constitute order, which in the case of migrants overrules the productive instruments that are used for 'Dutch' clients. By interpreting clients' behaviour in cultural terms and making them into strangers, physicians lose their ability to fine-tune their coaching activities to the needs of these clients. As a result migrants remain work incapacitated for a longer period, which leads to a higher risk of their ending up in the disability pension program. As a consequence migrants become visible as a problematic group in the data on work incapacity and disability. The practice to categorise migrant clients with separate instruments thus results in a 'hard' category of problematic migrant clients and leads to social differentiation.

    Studies of environmental exposures and childhood leukemia studies do not usually account for residential mobility. Yet, in addition to being a potential risk factor, mobility can induce selection bias, confounding, or measurement error in such studies. Using data collected for California Powerline Study (CAPS), we attempt to disentangle the effect of mobility. We analyzed data from a population-based case-control study of childhood leukemia using cases who were born in California and diagnosed between 1988 and 2008 and birth certificate controls. We used stratified logistic regression, case-only analysis, and propensity-score adjustments to assess predictors of residential mobility between birth and diagnosis, and account for potential confounding due to residential mobility. Children who moved tended to be older, lived in housing other than single-family homes, had younger mothers and fewer siblings, and were of lower socioeconomic status. Odds ratios for leukemia among non-movers living mobility, including dwelling type, increased odds ratios for leukemia to 2.61 (95% CI: 1.76-3.86) for living mobility of childhood leukemia cases varied by several sociodemographic characteristics, but not by the distance to the nearest power line or calculated magnetic fields. Mobility appears to be an unlikely explanation for the associations observed between power lines exposure and childhood leukemia. Copyright © 2018 Elsevier Inc. All rights reserved.

Predominance of the elements of two-level refinancing system of residential mortgage in Russia and the United States is shown. The activity of the Agency for Housing Mortgage Lending (AHML, the basic tool of the Russian government’s mortgage policy, is described in detail. In its objectives and functions the AHML is similar to the American mortgage agencies Ginnie Mae, Fannie Mae and Freddie Mac. Similarities were identified in the Russian and US residential mortgages in the pre-crisis period (high rates of mortgage growth, favourable economic conjuncture, low interest rates, large increase in house prices, speculative housing demand. During the mortgage crisis, the policies of the Russian and US governments and monetary authorities had also much in common (monetary policy easing, cheap central banks loans, extended facilities of mortgage refinancing on the part of state agencies, mortgage rescue scheme, social mortgage programs. But the scope of mortgage in Russia is enormously narrow as compared to the US mortgage. The most important reason for that - low incomes of the Russian population.

    Perceived behavioral control (PBC) is a consistent predictor of intentions to walk more. A previously successful intervention to promote walking by altering PBC has been adapted for delivery in general practice. This study aimed to evaluate the effect of this intervention on Theory of Planned Behavior (TPB) constructs in this context. Cluster randomized controlled trial, with n = 315 general practice patients. Practice nurses and Healthcare Assistants delivered a self-regulation intervention or information provision (control). Questionnaires assessed TPB variables at baseline, post-intervention, 6 weeks and 6 months. Walking was measured by pedometer. The control group reported significantly higher subjective norm at all follow-up time points. There were no significant differences between the two groups in PBC, intention, attitude or walking behavior. TPB variables significantly predicted intentions to walk more, but not objective walking behavior, after accounting for clustering. The lack of effect of the intervention was probably due to a failure to maintain intervention fidelity, and the unsuitability of the behavior change techniques included in the intervention for the population investigated. This previously successful intervention was not successful when delivered in this context, calling into question whether practice nurses are best placed to deliver such interventions.

  7. The feeding practices and structure questionnaire: construction and initial validation in a sample of Australian first-time mothers and their 2-year olds

    Science.gov (United States)

    2014-01-01

    Background Early feeding practices lay the foundation for children’s eating habits and weight gain. Questionnaires are available to assess parental feeding but overlapping and inconsistent items, subscales and terminology limit conceptual clarity and between study comparisons. Our aim was to consolidate a range of existing items into a parsimonious and conceptually robust questionnaire for assessing feeding practices with very young children (years). Methods Data were from 462 mothers and children (age 21–27 months) from the NOURISH trial. Items from five questionnaires and two study-specific items were submitted to a priori item selection, allocation and verification, before theoretically-derived factors were tested using Confirmatory Factor Analysis. Construct validity of the new factors was examined by correlating these with child eating behaviours and weight. Results Following expert review 10 factors were specified. Of these, 9 factors (40 items) showed acceptable model fit and internal reliability (Cronbach’s α: 0.61-0.89). Four factors reflected non-responsive feeding practices: ‘Distrust in Appetite’, ‘Reward for Behaviour’, ‘Reward for Eating’, and ‘Persuasive Feeding’. Five factors reflected structure of the meal environment and limits: ‘Structured Meal Setting’, ‘Structured Meal Timing’, ‘Family Meal Setting’, ‘Overt Restriction’ and ‘Covert Restriction’. Feeding practices generally showed the expected pattern of associations with child eating behaviours but none with weight. Conclusion The Feeding Practices and Structure Questionnaire (FPSQ) provides a new reliable and valid measure of parental feeding practices, specifically maternal responsiveness to children’s hunger/satiety signals facilitated by routine and structure in feeding. Further validation in more diverse samples is required. PMID:24898364

  8. A novel field measurement method for determining fine particle and gas emissions from residential wood combustion

    Science.gov (United States)

    Tissari, Jarkko; Hytönen, Kati; Lyyränen, Jussi; Jokiniemi, Jorma

    Emission data from residential wood combustion are usually obtained on test stands in the laboratory but these measurements do not correspond to the operational conditions in the field because of the technological boundary conditions (e.g. testing protocol, environmental and draught conditions). The field measurements take into account the habitual practice of the operators and provide the more reliable results needed for emission inventories. In this study, a workable and compact method for measuring emissions from residential wood combustion in winter conditions was developed. The emissions for fine particle, gaseous and PAH compounds as well as particle composition in real operational conditions were measured from seven different appliances. The measurement technique worked well and was evidently suitable for winter conditions. It was easy and fast to use, and no construction scaffold was needed. The dilution of the sample with the combination of a porous tube diluter and an ejector diluter was well suited to field measurement. The results indicate that the emissions of total volatile organic carbon (TVOC) (17 g kg -1 (of dry wood burned)), carbon monoxide (CO) (120 g kg -1) and fine particle mass (PM 1) (2.7 g kg -1) from the sauna stove were higher than in the other measured appliances. In the masonry heaters, baking oven and stove, the emissions were 2.9-9 g kg -1 TVOC, 28-68 g kg -1 CO and 0.6-1.6 g kg -1 PM 1. The emission of 12 PAHs (PAH 12) from the sauna stove was 164 mg kg -1 and consisted mainly of PAHs with four benzene rings in their structure. PAH 12 emission from other appliances was, on average, 21 mg kg -1 and was dominated by 2-ring PAHs. These results indicate that despite the non-optimal operational practices in the field, the emissions did not differ markedly from the laboratory measurements.

    Continually changing materials used in home construction and finishing can introduce new chemicals or changes in the VOC profile in residential air and the trend towards tighter homes can lead to higher exposure concentrations for many indoor sources. However, the complex mixture of VOCs in residential air makes it difficult to discover emerging contaminants and/or trends in pollutant profiles. The purpose of this study is to prepare a comprehensive library of chemicals found in homes, along with a semi-quantitative approach to maximize the information gained from VOC measurements. We carefully reviewed data from 108 new California homes and identified 238 individual compounds. The majority of the identified VOCs originated indoors. Only 31% were found to have relevant health based exposure guidelines and less than 10% had a chronic reference exposure level (CREL). The finding highlights the importance of extending IAQ studies to include a wider range of VOCs

    Psychiatric hospitals remain the main venue for long-term mental health care and, despite widespread closures and downsizing, no country that built asylums in the last century has done away with them entirely--with the recent exception of Italy. Differentiated community-based residential alternatives have been developed over the past decades, with staffing levels that range from full-time professional, to daytime only, to part-time/on-call. This paper reviews the characteristics of community-based psychiatric residential care facilities as an alternative to long-term care in psychiatric hospitals. It describes five factors decision makers should consider: 1. number of residential places needed; 2. staffing levels; 3. physical setting; 4. programming; and 5. governance and financing. In Italy, facilities with full-time professional staff have been developed since the mid-1990s to accommodate the last cohorts of patients discharged from psychiatric hospitals. In the United Kingdom, experiments with hostel wards since the 1980s have shown that home-like, small-scale facilities with intensive treatment and rehabilitation programming can be effective for the most difficult-to-place patients. More recently in Australia, Community Care Units (CCUs) have been applying this concept. In the Canadian province of British Columbia (BC), Tertiary Psychiatric Residential Facilities (TPRFs) have been developed as part of an effort to regionalise health and social services and downsize and ultimately close its only psychiatric hospital. This type of service must be further developed in addition to the need for forensic, acute-care and intermediate-level beds, as well as for community-based care such as assertive community treatment and intensive case management. All these types of services, together with long-term community-based residential care, constitute the elements of a balanced mental health care system. As part of a region's balanced mental health care plan, these Tertiary

    Scenario-based studies agree that the technical potential for CO 2 emissions reduction from the housing stock is large. This paper explores how a market might be developed for the refurbishment activities assumed in these scenarios, taking the existing market for repair, maintenance and improvement (RMI) as its starting point. Interviews with 16 small and medium-sized enterprises (SMEs) in the construction industry reveal the interdependence of products, practices and processes in housing renovation activities. Conservative practice as well as innovation can be understood as the outcome of multi-lateral influences on firms from other firms, clients, the material buildings and products in their working lives, and from regulations and regulators. Contractors' openness to innovation is contingent on an informal approach to risk assessment, taking account of cost, time efficiency, client demands, and installer confidence in the reliability of the resulting work. The implications of the research are discussed in relation to the need for new practices and processes on refurbishment projects, raising questions for future research on key questions of quality assurance, performance over time, the application of standards, and vocational training. -- Highlights: •Repair, maintenance and improvement works are triggers for low-carbon refurbishment. •Millions of property owners and small firms make for fragmented decision-making. •Actor-Network Theory is used to frame decision-making processes for refurbishment. •Small builders can be innovative if clients allow time and money for experimentation. •Energy policy for existing homes needs to engage with the construction sector

    The experiences and needs of spouses of residential care facility residents with dementia, regarding friendship, love, intimacy, and sexuality were explored. Understanding of how spouses make sense of their experiences was pursued. Semi-structured interviews were held with nine spouses of people with dementia, living in high intensive 24-hour care units within residential care facilities. The results show that friendship, love, intimacy, and sexuality were still embedded in the couples' marital lives, but all in their own way. Changing roles and a shift in purpose of the relationship recurred. Although intimacy was found to be still important in the lives of spouses, emotional, and practical residential care facility barriers were experienced by the spouses, of which the absence of communication were most important. Our findings on the experiences of spouses with regard to intimacy and sexuality can help residential care facility staff and policymakers to recognize the needs of couples and take these into account.

    Current practice in whole time series clustering of residential meter data focuses on aggregated or subsampled load data at the customer level, which ignores day-to-day differences within customers. This information is critical to determine each customer’s suitability to various demand side management strategies that support intelligent power grids and smart energy management. Clustering daily load shapes provides fine-grained information on customer attributes and sources of variation for subsequent models and customer segmentation. In this paper, we apply 11 clustering methods to daily residential meter data. We evaluate their parameter settings and suitability based on 6 generic performance metrics and post-checking of resulting clusters. Finally, we recommend suitable techniques and parameters based on the goal of discovering diverse daily load patterns among residential customers. To the authors’ knowledge, this paper is the first robust comparative review of clustering techniques applied to daily residential load shape time series in the power systems’ literature.

    Feasibility study was conducted on the technology for practical application of a several kW class fuel cell for the people's livelihood, particularly, for residential use. The study was made in six areas consisting of study on the present state of technology, conceptual design of a small fuel cell, survey on a promising market, basic concept of cell for residential use, feasibility study on application and on introduction. There is no record of development of the several kW class; while the fuel cell excels in the efficiency of energy utilization and the environmental conservation, its performance greatly deteriorates by start and stop under the present technology. Accordingly, it is a prerequisite that the equipment is for an electric heat combined type and for system interconnection. Also, while it is proper that the cell is phosphate type and that the fuel is natural gas, an innovation is necessary in the technology for reforming the cell and the fuel. The conceptual design revealed the possibility of a power generation system having a generating efficiency of 32%, exhaust heat recovery rate of 30%, and dimension of 75x65x150 cm. On the basis of a feasibility study on the application to the combination of a house and a beauty parlor, an advantage was recognized in the fuel unit cost of 5 yen/meal and the equipment cost of 200-250 thousand yen/kW, with demand estimated for 2.5 million installations nationwide including 950 thousand in natural gas supply districts.

    Residential building practice currently ignores the lossesof energy and water caused by the poor design of hot water systems. Theselosses include: combustion and standby losses from water heaters, thewaste of water (and energy) while waiting for hot water to get to thepoint of use; the wasted heat as water cools down in the distributionsystem after a draw; heat losses from recirculation systems and thediscarded warmth of waste water as it runs down the drain. Severaltechnologies are available that save energy (and water) by reducing theselosses or by passively recovering heat from wastewater streams and othersources. Energy savings from some individual technologies are reported tobe as much as 30 percent. Savings calculations of prototype systemsincluding bundles of technologies have been reported above 50 percent.This roundtable session will describe the current practices, summarizethe results of past and ongoing studies, discuss ways to think about hotwater system efficiency, and point to areas of future study. We will alsorecommend further steps to reduce unnecessary losses from hot waterdistribution systems.

    The integration of rooftop greenhouses (RTGs) in urban buildings is a practice that is becoming increasingly important in the world for their contribution to food security and sustainable development. However, the supply of tools and procedures to facilitate their implementation at the city scale is limited and laborious. This work aims to develop a specific and automated methodology for identifying the feasibility of implementation of rooftop greenhouses in non-residential urban areas, using airborne sensors. The use of Light Detection and Ranging (LIDAR) and Long Wave Infrared (LWIR) data and the Leica ALS50-II and TASI-600 sensors allow for the identification of some building roof parameters (area, slope, materials, and solar radiation) to determine the potential for constructing a RTG. This development represents an improvement in time and accuracy with respect to previous methodology, where all the relevant information must be acquired manually. The methodology has been applied and validated in a case study corresponding to a non-residential urban area in the industrial municipality of Rubí, Barcelona (Spain). Based on this practical application, an area of 36,312m 2 out of a total area of 1,243,540m 2 of roofs with ideal characteristics for the construction of RTGs was identified. This area can produce approximately 600tons of tomatoes per year, which represents the average yearly consumption for about 50% of Rubí total population. The use of this methodology also facilitates the decision making process in urban agriculture, allowing a quick identification of optimal surfaces for the future implementation of urban agriculture in housing. It also opens new avenues for the use of airborne technology in environmental topics in cities. Copyright © 2017 Elsevier B.V. All rights reserved.

    The totalitarian times of the 50s-80s of the 20th century have brought the building of high-rise residential blocks in Latvian cities, characterized by an uninteresting solution of standard buildings and the alien scale which does not meet the regional features. During the above period, areas of the residential courtyards have not been addressed. The conclusion of the research is that today the courtyards of the high-rise residential houses have become a stagnant, functionally irrelevant area that forms a depressing nature of the outdoor living space. The uncharted area of courtyards is not being used fully which highlights a wide range of issues that applies to car parks, recreation areas, and the green areas. With the development of the urban infrastructure, the creation of high-rise parking facilities and separate car parks are insufficiently addressed. Consequently, the implementation of improvements in courtyards of high-rise residential houses is not possible if the above issue on the removal of the car load from courtyards is not solved. Many building districts are characterized by the same compositional, architectural-spatial structure which even more influences and causes discomfort in these areas to stay. In recent years, the solution to the above issue is sought by the municipal authorities of Latvia to create a new courtyard zoning. It applies to the project development and construction works. In the research, courtyards of the city of Jelgava are analysed and evaluated which from the qualitative point of view demonstrates and is a vivid example where the issues of the research are readable. The city of Jelgava, located 45 km away from Riga, is an expressed satellite city and serves for the agglomeration of Riga as a huge high-rise residential district. Consequently, the research includes separate courtyards of high-rise residential buildings of the city of Jelgava and their study is carried out from the point of view of the architectural composition

    Full Text Available Key factors influencing electricity consumption in the residential sector in Poland have been identified. A fixed-effects model was used, which includes time effects, and a set of covariates, based on the model developed by Houthakker et al. This model estimates electricity demand by using lagged values of the dependent variable along with current and lagged values of electricity prices, and other variables that affect electricity demand such as: population, economic growth, income per capita, price of related goods, etc. The model has been identified according to the research results of the authors and those obtained by Bentzen and Engsted. The set of covariates was extended to the lagged electricity price given by a tariff (taken from two years previous to the time of interest and heating degree days index, a very important factor in European Union countries, where the climate is temperate. The authors propose four models of residential electricity demand, for which a confidence interval of 95% has been assumed. Estimation was based on Polish quarterly data for the years 2003-2013.

    The goals of this scoping study are to identify research needed to develop improved ventilation standards for California's Title 24 Building Energy Efficiency Standards. The 2008 Title 24 Standards are the primary target for the outcome of this research, but this scoping study is not limited to that timeframe. We prepared this scoping study to provide the California Energy Commission with broad and flexible options for developing a research plan to advance the standards. This document presents the findings of a scoping study commissioned by the Public Interest Energy Research (PIER) program of the California Energy Commission to determine what research is necessary to develop new residential ventilation requirements for California. This study is one of three companion efforts needed to complete the job of determining the ventilation needs of California residences, determining the bases for setting residential ventilation requirements, and determining appropriate ventilation technologies to meet these needs and requirements in an energy efficient manner. Rather than providing research results, this scoping study identifies important research questions along with the level of effort necessary to address these questions and the costs, risks, and benefits of pursuing alternative research questions. In approaching these questions and corresponding levels of effort, feasibility and timing were important considerations. The Commission has specified Summer 2005 as the latest date for completing this research in time to update the 2008 version of California's Energy Code (Title 24).

    Over time there have been changes in construction practices, building designs and materials and construction technologies. The Institute for Research in Construction (IRC) at the National Research Council of Canada (NRC) is undertaking research project to determine the impact of innovative residential construction products and systems on the fire safety of houses. The research study includes two phases: experimental and numerical. A new three-level full-scale experimental facility, representing a typical single-family house, has been built to study the structural fire performance, smoke movement and tenability conditions in the event of a fire. In the event of a fire in the first storey of a house, fire and smoke can move up to the main and second floors either through an open door or any openings in the floor structure between the basement and the main floor rendering the upper floor untenable for the occupants. Using CFD simulations this paper investigates the effect of the state of a stairwell door (opened or closed) on the fire development as well as on the moving up of the toxic gases to the upper floors. Simulation results were then used to estimate the time when conditions would become untenable, based on criteria found in the literature. (author)

    A novel hybrid cooling vest (HCV) incorporated with phase change materials (PCMs) and ventilation fans has been developed for construction workers in Hong Kong to attenuate heat stress and prevent heat-related illnesses, and its effectiveness and practicality have been validated in this study. A total of 140 wear trials involving of 140 workers were conducted in Hong Kong construction sites during the summer time. Each wear trial involves a two-day wear test, of which one day workers wore the HCV (denoted as VEST) during resting, and another day they wore traditional workwear (denoted as CON). Subjects were asked to rate their perceived exertion (RPE), thermal sensations (TS) and 7 other subjective attributes. There were significant differences in the effectiveness on reducing workers' heat strain between VEST and CON in terms of alleviations of heart rate (ΔHR), ΔTS, ΔRPE as well as ΔPeSI (p stress. In addition, a remarkable proportion of 91 per cent of subjects prefer to use this newly designed HCV as a cooling measure during rest. The power to alleviate perceptual heat stain (PeSA) in VEST is about twice of that by rest, which means HCV can notably improve the workers' perceptual heat strain in a limited resting duration. However, the strain alleviation power of HCV nearly remains unchanged with the prolonged rest duration. Thus, the optimal work-rest schedule needs to be investigated in a further study.

  9. Optimizing Hydronic System Performance in Residential Applications

    Energy Technology Data Exchange (ETDEWEB)

    Arena, L.; Faakye, O.

    2013-10-01

    Even though new homes constructed with hydronic heat comprise only 3% of the market (US Census Bureau 2009), of the 115 million existing homes in the United States, almost 14 million of those homes (11%) are heated with steam or hot water systems according to 2009 US Census data. Therefore, improvements in hydronic system performance could result in significant energy savings in the US. When operating properly, the combination of a gas-fired condensing boiler with baseboard convectors and an indirect water heater is a viable option for high-efficiency residential space heating in cold climates. Based on previous research efforts, however, it is apparent that these types of systems are typically not designed and installed to achieve maximum efficiency. Furthermore, guidance on proper design and commissioning for heating contractors and energy consultants is hard to find and is not comprehensive. Through modeling and monitoring, CARB sought to determine the optimal combination(s) of components - pumps, high efficiency heat sources, plumbing configurations and controls - that result in the highest overall efficiency for a hydronic system when baseboard convectors are used as the heat emitter. The impact of variable-speed pumps on energy use and system performance was also investigated along with the effects of various control strategies and the introduction of thermal mass.

    In order to stop the global warmth due to the CO2 concentration, the energy use should be decreased. The investment of building construction industry in Japan is about 20 percent of GDP. This fraction is much higher than in most developed countries. That results the Japanese building construction industry including residential use consumes about one third of all energy and resources of the entire industrial sectors. In order to save energy as well as resource, the recycle of the building materials should be urgent to be carried out. In this paper, we focus on the potential energy savings with a simple calculated method when the building materials or products are manufactured from recycled materials. We examined three kinds of residential buildings with different construction techniques and estimated the decreased amount of energy consumption and resources resulting from use of recycled materials. The results have shown for most building materials, the energy consumption needed to remake housing materials from recycled materials is lower than that to make new housing materials. The energy consumption of building materials in all case-study housing can be saved by at least 10 percent. At the same time, the resource, measured by mass of building materials (kg) can be decreased by over 50 percent

    The construction industry is well-known for producing waste detrimental to the environment, and its impacts have increased with the development process of cities. Although there are several studies focused on the environmental impact of residential and commercial buildings, less knowledge is available regarding decreasing construction waste (CW) generation in urban infrastructure projects. This study presents best practices to reduce waste in the said projects, stressing the role of decision-making in the design stage and the effective management of construction processes in public sector. The best practices were identified from literature review, document analysis in 14 projects of urban infrastructure, and both qualitative and quantitative survey with 18 experts (architects and engineers) playing different roles on those projects. The contributions of these research are: (i) the identification of the main building techniques related to the urban design typologies analyzed; (ii) the identification of cause-effect relationships between the design choices and the CW generation diagnosis; (iii) the proposal of a checklist to support the decision-making process, that can be used as a control and evaluation instrument when developing urban infrastructure designs, focused on the construction waste minimization (CWM).

    2013-10-01

    The United States Coast Guard (USCG) constructs residential housing throughout the country using a basic template that must meet the minimum Leadership in Energy and Environmental Design (LEED) Silver criteria or better for the units. In Kodiak, Alaska, USCG is procuring between 24 and 100 residential multi-family housing units. Priorities for the Kodiak project were to reduce overall energyconsumption by at least 20% over existing units, improve envelope construction, and evaluate space heating options. USCG is challenged with maintaining similar existing units that have complicated residential diesel boilers. Additionally, fuel and material costs are high in Kodiak. While USCG has worked to optimize the performance of the housing units with principles of improved buildingenvelope, the engineers realize there are still opportunities for improvement, especially within the heating, ventilation, and air conditioning (HVAC) system and different envelope measures. USCG staff also desires to balance higher upfront project costs for significantly reduced life-cycle costs of the residential units that have an expected lifetime of 50 or more years. To answer thesequestions, this analysis used the residential modeling tool BEoptE+ to examine potential energy- saving opportunities for the climate. The results suggest criteria for achieving optimized housing performance at the lowest cost. USCG will integrate the criteria into their procurement process. To achieve greater than 50% energy savings, USCG will need to specify full 2x 6 wood stud R-21 insulationwith two 2 inches of exterior foam, R-38 ceiling insulation or even wall insulation in the crawl space, and R-49 fiberglass batts in a the vented attic. The air barrier should be improved to ensure a tight envelope with minimal infiltration to the goal of 2.0 ACH50. With the implementation of an air source heat pump for space heating requirements, the combination of HVAC and envelope savings inthe residential unit can save

After describing this online master’s program in adult education designed from a social constructivist theoretical frame, this paper discusses two primary areas of findings related to cohort learning. First, were those related to the ongoing negotiation of the learning process: the importance of an opening residential; a consistent but flexible cohort structure; and building ongoing relationships. Second, were those related to the ongoing construction of knowledge: the role of team-teaching and the cohort model in transformative learning; the application of theory to real life practice, and the value of group support and collaboration in conducting research and constructing knowledge. Implications for practice are discussed.

  18. Residential electricity demand in Singapore

    International Nuclear Information System (INIS)

    1992-01-01

    Residential electricity consumption in Singapore increased at a rate of 8.8% per year between 1972 and 1990. Estimates of the long-run income and price elasticities are 1.0 and -0.35, respectively. The energy-conservation campaigns that have been launched are found to have marginal effects on consumption. A statistical analysis shows that the consumption is sensitive to small changes in climatic variables, particularly the temperature, which is closely linked to the growing diffusion of electric appliances for environmental controls. There has been a temporal increase in the ownership levels of appliances associated with increasing household incomes. However, other factors were involved since the ownership levels would also increase over time after the elimination of the income effect. A large part of the future growth in electricity demand will arise from the growing need for air-conditioning, which will lead to increasingly large seasonal variations in electricity use. (author)

    Recognizing the importance of energy conservation, under sponsorship of the US Department of Energy, Cornell University conducted a research and demonstration project entitled An Innovative Educational Program for Residential Energy Efficiency. The research project examined the amount of residential energy that can be saved through changes in behavior and practices of household members. To encourage these changes, a workshop was offered to randomly-selected households in New York State. Two surveys were administered to household participants (Survey 1 and Survey 2, Appendix A) and a control group; and a manual was developed to convey many easy but effective ways to make a house more energy efficient (see Residential Manual, Appendix B). Implementing methods of energy efficiency will help reduce this country`s dependence on foreign energy sources and will also reduce the amount of money that is lost on inefficient energy use. Because Cornell Cooperative Extension operates as a component of the land-grant university system throughout the US, the results of this research project have been used to develop a program that can be implemented by the Cooperative Extension Service nationwide. The specific goals and objectives for this project will be outlined, the population and sample for the research will be described, and the instruments utilized for the survey will be explained. A description of the workshop and manual will also be discussed. This report will end with a summary of the results from this project and any observed changes and/or recommendations for future surveys pertaining to energy efficiency.

    Cecile Massart is a visual artist who lives and works in Brussels, Belgium. Her teaching career includes Academy of Ixelles, Ecole Superieure des Arts Plastiques et Visuels in Mons, and Ecole Nationale Superieure des Arts Visuels La Cambre in Brussels. Cecile Massart has presented her extensive artistic research at numerous international conferences. Her works are featured in private and public collections. Since 1994, Cecile Massart has been investigating international sites for radioactive waste storage, exploring how this 21. century archaeological stratum is being inscribed in the landscape. Researching radioactive waste sites around the world for over 20 years, her main focus has become their identification in the landscape. Her ideas are communicated through her visual research and writings that aim to raise the awareness of radioactive disposal sites and to study their life within their surroundings for future generations. Her drawings, films, books and exhibitions investigate a new kind of architecture of the sites that become research platforms. Her first graphic research, edited under the title Un site archive pour Alpha, Beta, Gamma, helps in revealing their true nature. Her photographs, silk-screen prints, installations and pictures testify to the need to preserve the memory and knowledge of such sites across generations ensuring the safety of the living world. With this objective in mind, to build a memory, she has developed an architectural vocabulary functioning as warning sculptures to identify the nuclear repositories in the landscape: markers or archi-sculptures. In the following sections, Cecile Massart describes her work in her own words. For more details on her work, see www.cecilemassart.com

  2. Unsightly urban menaces and the rescaling of residential segregation in the United States.

    Science.gov (United States)

    Hanlon, James

    2011-01-01

    In this article, the author uses a slum clearance project in Lexington, Kentucky, as a lens through which to examine the spatial dynamics of racial residential segregation during the first half of the twentieth century. At the time, urban migration and upward socioeconomic mobility on the part of African Americans destabilized extant residential segregation patterns. Amid this instability, various spatial practices were employed in the interest of maintaining white social and economic supremacy. The author argues that such practices were indicative of a thoroughgoing reinvention of urban socio-spatial order that in turn precipitated the vastly expanded scale of residential segregation still found in U.S. cities today. Evidence of this reinvented ordering of urban space lies in the rendering of some long-standing African American neighborhoods as “out of place” within it and the use of slum clearance to remove the “menace” such neighborhoods posed to it.

  3. A construção da identidade de diretores: discurso oficial e prática Construction of the identity of principals: official discourse and practice

    Full Text Available Este estudo abordará a construção da identidade de diretores de escola sob dois enfoques: à luz do discurso oficial, por meio do estudo de documentos e legislações que definem seu "perfil", e por meio do discurso dos diretores, ao caracterizar sua atuação na prática cotidiana da escola. O pressuposto do estudo é o de que a identidade de diretores é o conjunto das representações colocadas em circulação tanto pelos discursos oficiais quanto pelos modos de ser e agir dos gestores de escola no exercício de suas funções. Um dos pontos de análise relaciona-se à contribuição da estrutura burocrática e centralizadora que permeia as instituições sociais no Brasil, na construção da identidade oficial estabelecida para os diretores de escola. A discussão da construção da identidade de diretores de escola tem importância na medida em que se insere nas expectativas sobre a atuação deles em diferentes momentos históricos.This study discusses the identity construction of school's principals in two approaches: the public discourse present in the documents and laws that define their "profile" and the discourse of directors to characterize their performance in the every day schools practices. The assumption of the study is that the identity of principals is the set of representations put into circulation by both the official discourse about the ways of being and acting school managers in performing their duties. One aspect of analysis relates to the contribution of bureaucratic and centralized structure, which permeates the social institutions in Brazil in the construction of official identity established for school principals. The discussion of identity construction of school principals has its importance in that it falls in expectations about the performance of the same in different historical moments.

    In China, more than 80% electricity comes from coal which dominates the CO2 emissions. Residential electricity demand forecasting plays a significant role in electricity infrastructure planning and energy policy designing, but it is challenging to make an accurate forecast for developing countries. This paper forecasts the provincial residential electricity consumption of China in the 13th Five-Year-Plan (2016-2020) period using panel data. To overcome the limitations of widely used predication models with unreliably prior knowledge on function forms, a robust piecewise linear model in reduced form is utilized to capture the non-deterministic relationship between income and residential electricity consumption. The forecast results suggest that the growth rates of developed provinces will slow down, while the less developed will be still in fast growing. The national residential electricity demand will increase at 6.6% annually during 2016-2020, and populous provinces such as Guangdong will be the main contributors to the increments.

    2013-10-01

    Home fires account for 85% of fire deaths in the United States, the majority in 1- or 2-family homes lacking fire sprinklers. Since 1978, however, a grassroots movement has successfully promoted more than 360 local ordinances mandating sprinklers in all new residential construction, including 1- and 2-family homes. The homebuilding industry has responded by seeking state preemption of local authority, a strategy previously used by other industries concerned about protecting their profits. From 2009 through 2011, 13 states adopted laws eliminating or limiting local authority over residential fire sprinklers. This study of the residential sprinkler movement adds to our understanding of grassroots public health movements and provides additional evidence that preemption can have a negative impact on public health and safety.

    2010-01-01

    The European Directive on Energy Performance of Buildings (EPBD) imposes the adoption of measures for improving the energy efficiency in buildings. These measures should take into account the local weather conditions as well as internal thermal environment and cost-effectiveness. In this respect, Italy is a very interesting benchmark. For Northern Italy, the climatic context is particularly difficult to deal with cold winters and hot summers. The legislations are changing very rapidly, but has not fully adapted to the local context. The considered methodology still involves winter heating while summer cooling is addressed in incomplete and inadequate ways. The energy issue is addressed only partially as final energy consumption, but with little attention to LCA. Moreover, the belief that the buildings with high energy savings are too expensive, and therefore not attractive from economic point of view. For these reasons, it is very important to develop case studies to demonstrate the effectiveness of sustainable energy in architecture, according to a holistic approach. This paper describes a detailed techno-economic analysis for Borgo Solare project, an extremely advanced and innovative residential settlement designed on sustainable architecture concepts. One of the most innovative aspects of the project is that it is not just an experimental operation but Borgo Solare is a real urban district, which will be built without public funds and should be inhabited by common people. Excellent energy performance, therefore, must be accompanied by affordable market prices. The energy and economical analysis is presented taking into account also the embodied energy of the building. The results on the performance of a sample building (case study) of this settlement are reported, according to different construction standards: prior to EPBD, present from the EPBD and more efficient developed specifically for the project. It has been shown that using the better design practices

    Suburban landscapes are known to have degraded water quality relative to natural settings, including increased total phosphorus (TP) levels; however, the effect of subdivision construction activities on stream TP dynamics are less understood. This study measured TP and its constituents particulate, dissolved organic, and dissolved inorganic phosphorus (PP, DOP, and DIP, respectively) in two headwater streams of contrasting urbanization activity to examine whether the land-use conversion process itself contributed to TP concentrations and export. The nested watershed undergoing significant active residential community construction contained large areas of cleared former agricultural field and associated sediment mounds with elevated soil TP (~1000 mg kg -1 ), and twice as many stormwater management (SWM) ponds than the watershed with completed suburban communities. Daily stream sampling for six months revealed limited differences in TP between urbanized and urbanizing watersheds regardless of season or stream flow condition; however, the forms of TP varied significantly. The proportion of TP as DOP was consistently higher in the urbanizing stream relative to the urban stream, which was in line with significant decreases in DOP concentration as proportion of cleared former agricultural land decreased and density of SWM ponds increased. The DOP, and to a lesser extent DIP and PP, dynamics resulted in a 2.5× greater areal export of TP from a small watershed actively being suburbanized during the study period compared to the larger watershed with greater land urbanized 3-5 years ago. The results of this study suggest stream TP concentrations are relatively unresponsive to active versus established suburban cover, but the forms of TP can be quite different, and the period of home construction can increase phosphorus (P) delivery to and export through nearby streams. This information can aid land managers and urban planners update best management practices to

    In 1986, Pacific Northwest Laboratory developed the Residential Occupant Survey-Spring '86, which was implemented. The overall purpose of the study was to collect demographic, attitudinal, and behavioral data related to the use and conservation of electricity in dwellings participating in the Bonneville Power Administration's End-Use Load and Conservation Assessment Program (ELCAP). Information was collected on the respondents' perceptions of the energy efficiency of their dwelling, temperature the dwelling was kept when people were at home and awake during the last heating season, which rooms, if any, were not heated during the last heating season, number of times the dwelling was unoccupied for at least one week, number of times pets were let out of the dwelling per day, attitudes toward energy use and conservation and several socio-demographic variables such as age, sex, and total household income. The results of the data analyses showed age to be an important factor for reported indoor temperature and perceived energy efficiency of the dwelling. The results also showed that almost 60% of the ELCAP occupants do not heat one or more rooms during the heating season, and almost 45% of the ELCAP dwellings were unoccupied for at least one week during the reporting period. In terms of the reported allocation of household income for household energy expenses, the results showed that the reported dollar amount spent for the expenses remained relatively constant over income levels.

  17. Residential Buildings of the Turkish Republican Period as Architectural Heritage in Aydın

    Directory of Open Access Journals (Sweden)

    Gökçe ŞİMŞEK

    2015-02-01

    Full Text Available At the end of the 19th century, Aydın was both a sanjak center and an important commercial center. It was connected to Izmir via Anatolia’s first railway line and was the commercial center through which the produce of central Anatolia was transferred to the port of İzmir. During the War of Independence, most of Aydin’s structures were destroyed and the center left almost entirely abandoned. After the foundation of the Turkish Republic, many efforts were made to rebuild and revitalize the settlement according to a new city plan. In the years following the war, as residential numbers increased, new housing was built as required. In this context, the current study aimed to define the architectural characteristics, value, potential and preservation problems of those registered residential buildings built between 1923 and 1950 in the city. The study presents a comprehensive look at the architectural characteristics of residential buildings in Aydın, and reveals how difficulties in identifying and registering architectural products of the Turkish Republican period is exemplified in the case of the city’s residential buildings. The study also shows that the architectural characteristics of residential buildings constructed between 1923 and 1950 represent both the new face of the Turkish Republic and the traditional living styles of the people of Aydın.

  18. Particulate and gaseous emissions from residential biomass combustion

    2005-04-01

    Biomass is considered to be a sustainable energy source with significant potentials for replacing electricity and fossil fuels, not at least in the residential sector. However, present wood combustion is a major source of ambient concentrations of hydrocarbons (e.g. VOC and PAH) and particulate matter (PM) and exposure to these pollutants have been associated with adverse health effects. Increased focus on combustion related particulate emissions has been seen concerning the formation, characteristics and implications to human health. Upgraded biomass fuels (e.g. pellets) provide possibilities of more controlled and optimized combustion with less emission of products of incomplete combustion (PICs). For air quality and health impact assessments, regulatory standards and evaluations concerning residential biomass combustion, there is still a need for detailed emission characterization and quantification when using different fuels and combustion techniques. This thesis summarizes the results from seven different papers. The overall objective was to carefully and systematically study the emissions from residential biomass combustion with respect to: i) experimental characterization and quantification, ii) influences of fuel, appliance and operational variables and iii) aspects of ash and trace element transformations and aerosol formation. Special concern in the work was on sampling, quantification and characterization of particulate emissions using different appliances, fuels and operating procedures. An initial review of health effects showed epidemiological evidence of potential adverse effect from wood smoke exposure. A robust whole flow dilution sampling set-up for residential biomass appliances was then designed, constructed and evaluated, and subsequently used in the following emission studies. Extensive quantifications and characterizations of particulate and gases emissions were performed for residential wood and pellet appliances. Emission factor ranges for

    Stated-preference methods are a class of evaluation techniques for studying the preferences of patients and other stakeholders. While these methods span a variety of techniques, conjoint-analysis methods-and particularly discrete-choice experiments (DCEs)-have become the most frequently applied approach in health care in recent years. Experimental design is an important stage in the development of such methods, but establishing a consensus on standards is hampered by lack of understanding of available techniques and software. This report builds on the previous ISPOR Conjoint Analysis Task Force Report: Conjoint Analysis Applications in Health-A Checklist: A Report of the ISPOR Good Research Practices for Conjoint Analysis Task Force. This report aims to assist researchers specifically in evaluating alternative approaches to experimental design, a difficult and important element of successful DCEs. While this report does not endorse any specific approach, it does provide a guide for choosing an approach that is appropriate for a particular study. In particular, it provides an overview of the role of experimental designs for the successful implementation of the DCE approach in health care studies, and it provides researchers with an introduction to constructing experimental designs on the basis of study objectives and the statistical model researchers have selected for the study. The report outlines the theoretical requirements for designs that identify choice-model preference parameters and summarizes and compares a number of available approaches for constructing experimental designs. The task-force leadership group met via bimonthly teleconferences and in person at ISPOR meetings in the United States and Europe. An international group of experimental-design experts was consulted during this process to discuss existing approaches for experimental design and to review the task force's draft reports. In addition, ISPOR members contributed to developing a consensus

    Pomonis, A

    1990-06-01

    The 1988 earthquake in Armenia was the most serious seismic disaster since the 1976 earthquake in Tangshan, China. At least 25,000 people lost their lives in a tremor of moderate magnitude and the USSR suffered a loss of more than 2.5 per cent of 1988's GDP. Research at the Martin Centre on the effects of earthquakes on human lives has shown an increase in global earthquake mortality rate, despite the well known improvements in some countries. The Armenian disaster was a warning to all of us concerned with natural or man-made disasters. Areas of potential high hazard are pointed out for the sub-Caucasian region. Construction practices similar to those in Armenia are certainly found in many other parts of the world, with some regional variations, and the fast assimilation of the lessons is an important target. The structural characteristics of all the residential building types existing in the affected area are presented in terms of their seismic vulnerability. Vulnerable points are discussed with a view to low cost interventions that will drastically improve the seismic safety of new buildings.

    This study examined a range of factors influencing energy consumption in households that had participated in residential energy-efficiency upgrades. The study was funded by a grant from the U.S. Department of Energy’s Pacific Northwest National Laboratory and was conducted by faculty and staff of Portland State University Center for Urban Studies and Department of Economics. This work was made possible through the assistance and support of the Energy Trust of Oregon (ETO), whose residential energy-efficiency programs provided the population from which the sample cases were drawn. All households in the study had participated in the ETO Home Performance with Energy Star (HPwES) program. A number of these had concurrently pursued measures through other ETO programs. Post-retrofit energy outcomes are rarely investigated on a house-by-house basis. Rather, aggregate changes are ordinarily the focus of program impact evaluations, with deviation from aggregate expectations chalked up to measurement error, the vagaries of weather and idiosyncrasies of occupants. However, understanding how homes perform post-retrofit on an individual basis can give important insights to increase energy savings at the participant and the programmatic level. Taking a more disaggregated approach, this study analyzed energy consumption data from before and after the retrofit activity and made comparisons with engineering estimates for the upgrades, to identify households that performed differently from what may have been expected based on the estimates. A statistical analysis using hierarchal linear models, which accounted for weather variations, was performed looking separately at gas and electrical use during the periods before and after upgrades took place. A more straightforward comparison of billing data for 12-month periods before and after the intervention was also performed, yielding the majority of the cases examined. The later approach allowed total energy use and costs to be

    High-level occupational radon exposure is an established risk factor for lung cancer. We assessed the long-term association between residential radon and lung cancer risk using a prospective Danish cohort using 57,053 persons recruited during 1993-1997. We followed each cohort member for cancer occurrence until 27 June 2006, identifying 589 lung cancer cases. We traced residential addresses from 1 January 1971 until 27 June 2006 and calculated radon at each of these addresses using information from central databases regarding geology and house construction. Cox proportional hazards models were used to estimate incidence rate ratios (IRR) and 95% confidence intervals (CI) for lung cancer risk associated with residential radon exposure with and without adjustment for sex, smoking variables, education, socio-economic status, occupation, body mass index, air pollution and consumption of fruit and alcohol. Potential effect modification by sex, traffic-related air pollution and environmental tobacco smoke was assessed. Median estimated radon was 35.8 Bq/m{sup 3}. The adjusted IRR for lung cancer was 1.04 (95% CI: 0.69-1.56) in association with a 100 Bq/m{sup 3} higher radon concentration and 1.67 (95% CI: 0.69-4.04) among non-smokers. We found no evidence of effect modification. We find a positive association between radon and lung cancer risk consistent with previous studies but the role of chance cannot be excluded as these associations were not statistically significant. Our results provide valuable information at the low-level radon dose range.

Potential effect modification by sex, traffic-related air pollution and environmental tobacco smoke was assessed. Median estimated radon was 35.8 Bq/m 3 . The adjusted IRR for lung cancer was 1.04 (95% CI: 0.69–1.56) in association with a 100 Bq/m 3 higher radon concentration and 1.67 (95% CI: 0.69–4.04) among non-smokers. We found no evidence of effect modification. We find a positive association between radon and lung cancer risk consistent with previous studies but the role of chance cannot be excluded as these associations were not statistically significant. Our results provide valuable information at the low-level radon dose range.

  7. Residential architecture of George Pavlovic Kovalevsky in interwar Belgrade

    Full Text Available George Pavlovic Kovalevsky, architect and urban planner, belongs to the most significant authors who created in the period between the Two World Wars in Belgrade. Yet, his work and life have rarely been the subject of scholarly literature, while the study of his housing projects has been overlooked. This paper discusses housing projects designed by Kovalevsky mainly in collaboration with another Russian architect Vladimir Bilinski. The analysis of the projects is based on original archival plans, documents and photographs. Residential buildings designed during 1921-1923 by these two architects include small single-storey houses, multi-storey building and spacious villas. Although of different surface, volume and shape, they have some common characteristics such as: classical construction, equable aesthetic quality that followed the spirit of the late Secession or the modernized Academicism, and were designed in line with the requirements of the property-owners. Buildings created by Kovalevsky and Bilinski cannot be considered among the most important achievements of the interwar Belgrade residential architecture, but their study is important because it contributes to a better understanding and evaluation of the work of these authors, as well as the overall architectural production of that period. In a broader sense, this paper builds upon general rise in interest in the revaluation of cultural, social and historical values of residential architecture in Belgrade that was created in the late 19th and the first half of the 20th century, as an important segment of the material and immaterial cultural heritage and the identity of the city and contributes to its more adequate interpretation and preservation.

    Combustion of solid biofuels, peat and different types of waste in Sweden for the purpose of energy production generates approximately 1.3 million tonnes of residues yearly. These have varying chemical and technical properties, depending on the type of fuel, the combustion process and the type of furnace. From a technical point of view, some of the ashes may be used for civil works. However, the Swedish Environmental Code requires that operators obtain a permit from the local environmental authorities if ashes are utilized for construction purposes. Previous studies on the application and permitting process have indicated that it can be improved, in particular both the information provided by the operators and the decision process. The stakeholders involved in the decision process have expressed that they have limited knowledge on expected environmental impacts from the utilization of ashes in civil works and that existing knowledge not is being fully applied in practice. The aim of this project was to improve the decision support for permit application of ash utilization in constructions. The goals were to - initiate and develop the discussion regarding which information should be used in the decision process - suggest the scope and content of the information to be supplied in the permit application - contribute to improved communication between different stakeholders - identify possibilities of using the knowledge obtained by research for decision support The stakeholders' (operators and environmental authorities) opinions and viewpoint on the assessment and application process were achieved through interviews. The results from the interviews were presented and discussed during a seminar. Both the interviews and the seminar provided information, but at the same time they served to initiate a discussion on permit application procedure and to increase the communication between different stakeholders. The outcomes from these activities (interviews and seminar

    This study investigated the different facets of job satisfaction that influence community care and residential care employees' intention to stay in the aged care workforce. A survey of four organisations in Australia was undertaken. t-Tests were conducted to analyse differences between groups. Regression analyses were performed to examine the factors influencing intentions to stay in the workforce. Community care workers were more satisfied with various facets of job satisfaction including work on their present job, supervision, people in their present job and the job in general. There was a difference between how the various facets of job satisfaction influenced intentions to stay for residential care compared to community care workers. Both workers were satisfied with their work conditions and work to different extents. There is an opportunity for residential care to look to the practices within the community care sector to improve employees' intentions to stay. © 2017 AJA Inc.

    The issues of constructing high-rise, primarily residential, buildings have a great social significance. Not every plot of land, acquired in the Russian Federation is suitable for high-rise construction. Therefore, every construction company that plans to erect a multi-apartment building, a high-rise office building, or a skyscraper must take into account not only technical norms but as well sanitary legislation regulations that set obligatory requirements about insolation of apartments. The article includes a short study of several norms in the Russian legislation regarding insolation of dwellings; analises the problems of judicial interpretation of the statutory limitations. In this aspect it researches the debatable questions arising in practice of state arbitration courts dealing with the lawsuits on allocation of land-plots by the local administration. The analysis of the judicial practice is followed by description of the difficulties facing the developers of land-plots, concerning the project and territorial planning documentation.

    2018-02-01

    There have been calls for uncovering the "black box" of residential care services, with a particular need for research focusing on emergency care settings for children and youth in danger. In fact, the strikingly scant empirical attention that these settings have received so far contrasts with the role that they often play as gateway into the child welfare system. To answer these calls, this work presents and tests a framework for assessing a service model in residential emergency care. It comprises seven studies which address a set of different focal areas (e.g., service logic model; care experiences), informants (e.g., case records; staff; children/youth), and service components (e.g., case assessment/evaluation; intervention; placement/referral). Drawing on this process-consultation approach, the work proposes a set of key challenges for emergency residential care in terms of service improvement and development, and calls for further research targeting more care units and different types of residential care services. These findings offer a contribution to inform evidence-based practice and policy in service models of residential care. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Integration of small combined heat and power systems (CHP) into residential buildings is challenging as the loads are small, the load diversity is limited and there are a number of unresolved issues concerning sizing, control, peak loads, emergency operation, grid connection and export, etc. Natural Resources Canada has undertaken an initiative to investigate and develop techniques for the integration of small CHP systems into residential buildings using a highly instrumented house modified to allow quick installation and thorough monitoring of CHP integration techniques as well determining the performance of the CHP systems themselves when operating in a house. The first CHP system installed was a Stirling engine residential CHP system. It was used to examine the completeness of the CHP modifications to the house, to evaluate various building integration techniques and to measure the performance of the CHP system itself. The testing demonstrated the modified house to be an excellent facility for the development of CHP building integration techniques and the testing of residential CHP systems. The Stirling engine CHP system was found to operate well and produce meaningful input to the house. A second system (residential fuel cell) is presently being installed and building integration techniques and the performance of the fuel cell will be tested over the coming year. (author)

    2012-10-01

    Full Text Available The increasing deployment of distributed generation systems based on renewables in the residential sector, the development of information and communication technologies and the expected evolution of traditional power systems towards smart grids are inducing changes in the passive role of end-users, namely with stimuli to change residential demand patterns. The residential user should be able to make decisions and efficiently manage his energy resources by taking advantages from his flexibility in load usage with the aim to minimize the electricity bill without depreciating the quality of energy services provided. The aim of this paper is characterizing electricity consumption in the residential sector and categorizing the different loads according to their typical usage, working cycles, technical constraints and possible degree of control. This categorization of end-use loads contributes to ascertain the availability of controllable loads to be managed as well as the different direct management actions that can be implemented. The ability to implement different management actions over diverse end-use load will increase the responsiveness of demand and potentially raises the willingness of end-users to accept such activities. The impacts on the aggregated national demand of large-scale dissemination of management systems that would help the end-user to make decisions regarding electricity consumption are predicted using a simulator that generates the aggregated residential sector electricity consumption under variable prices.

    2013-01-01

    Full Text Available Residential neighbourhoods developed using various techniques in Kathmandu by both the public and private sectors have not only provided a poor urban setting and failed to address socio-cultural needs, but are also poor at building a community and creating links to the built environment, with the result that the planned areas lack a sense of place and the inhabitants lack a feeling of home. Although traditional neighbourhoods in the historic core area had many features of a good residential neighbourhood in the past, they are currently undergoing rapid destruction. The residents of these neighbourhoods have little awareness of these issues. The existing legal and institutional frameworks are inadequate and ineffective and cannot address these problems, and so the formulation of design guidelines, their strict implementation, and enhancement of socio-cultural events including social networking are recommended for future residential neighbourhood development.

    2016-11-01

    Gentrification has provoked considerable controversy surrounding its effects on residential displacement. Using a unique individual-level, longitudinal data set, this study examines mobility rates and residential destinations of residents in gentrifying neighborhoods during the recent housing boom and bust in Philadelphia for various strata of residents and different types of gentrification. We find that vulnerable residents, those with low credit scores and without mortgages, are generally no more likely to move from gentrifying neighborhoods compared with their counterparts in nongentrifying neighborhoods. When they do move, however, they are more likely to move to lower-income neighborhoods. Residents in gentrifying neighborhoods at the aggregate level have slightly higher mobility rates, but these rates are largely driven by more advantaged residents. These findings shed new light on the heterogeneity in mobility patterns across residents in gentrifying neighborhoods and suggest that researchers should focus more attention on the quality of residential moves and nonmoves for less advantaged residents, rather than mobility rates alone.

    As broadband gains widespread adoption with residential users, revenue generating voice- and video-services have not yet taken off. This slow uptake is often attributed to lack of Quality of Service management in residential broadband networks. To resolve this and induce service variety, network...... access providers are implementing service differentiation in their networks where voice and video gets prioritised before data. This paper discusses the role of network access providers in multipurpose packet based networks and the available migration strategies for supporting multimedia services...... in digital subscriber line (DSL) based residential broadband networks. Four possible implementation scenarios and their technical characteristics and effects are described. To conclude, the paper discusses how network access providers can be induced to open their networks for third party service providers....

    2009-03-01

    This report presents the information that homeowners and policy makers need to facilitate PV financing at the residential level. The full range of cash payments, bill savings, and tax incentives is covered, as well as potentially available solar attribute payments. Traditional financing is also compared to innovative solutions, many of which are borrowed from the commercial sector. Together, these mechanisms are critical for making the economic case for a residential PV installation, given its high upfront costs. Unfortunately, these programs are presently limited to select locations around the country. By calling attention to these innovative initiatives, this report aims to help policy makers consider greater adoption of these models to benefit homeowners interested installing a residential PV system.

    Full Text Available Abstract Background Insight in parental energy balance-related behaviours, their determinants and parenting practices are important to inform childhood obesity prevention. Therefore, reliable and valid tools to measure these variables in large-scale population research are needed. The objective of the current study was to examine the test-retest reliability and construct validity of the parent questionnaire used in the ENERGY-project, assessing parental energy balance-related behaviours, their determinants, and parenting practices among parents of 10–12 year old children. Findings We collected data among parents (n = 316 in the test-retest reliability study; n = 109 in the construct validity study of 10–12 year-old children in six European countries, i.e. Belgium, Greece, Hungary, the Netherlands, Norway, and Spain. Test-retest reliability was assessed using the intra-class correlation coefficient (ICC and percentage agreement comparing scores from two measurements, administered one week apart. To assess construct validity, the agreement between questionnaire responses and a subsequent interview was assessed using ICC and percentage agreement. All but one item showed good to excellent test-retest reliability as indicated by ICCs > .60 or percentage agreement ≥ 75%. Construct validity appeared to be good to excellent for 92 out of 121 items, as indicated by ICCs > .60 or percentage agreement ≥ 75%. From the other 29 items, construct validity was moderate for 24 and poor for 5 items. Conclusions The reliability and construct validity of the items of the ENERGY-parent questionnaire on multiple energy balance-related behaviours, their potential determinants, and parenting practices appears to be good. Based on the results of the validity study, we strongly recommend adapting parts of the ENERGY-parent questionnaire if used in future research.

    2011-01-01

    This research investigates the relationship between Turkish residential electricity consumption, household total final consumption expenditure and residential electricity prices by applying the structural time series model to annual data over the period from 1960 to 2008. Household total final consumption expenditure, real energy prices and an underlying energy demand trend are found to be important drivers of Turkish residential electricity demand with the estimated short run and the long run total final consumption expenditure elasticities being 0.38 and 1.57, respectively, and the estimated short run and long run price elasticities being -0.09 and -0.38, respectively. Moreover, the estimated underlying energy demand trend, (which, as far as is known, has not been investigated before for the Turkish residential sector) should be of some benefit to Turkish decision makers in terms of energy planning. It provides information about the impact of past policies, the influence of technical progress, the impacts of changes in consumer behaviour and the effects of changes in economic structure. Furthermore, based on the estimated equation, and different forecast assumptions, it is predicted that Turkish residential electricity demand will be somewhere between 48 and 80 TWh by 2020 compared to 40 TWh in 2008. - Research highlights: → Estimated short run and long run expenditure elasticities of 0.38 and 1.57, respectively. → Estimated short run and long run price elasticities of -0.09 and -0.38, respectively. → Estimated UEDT has increasing (i.e. energy using) and decreasing (i.e. energy saving) periods. → Predicted Turkish residential electricity demand between 48 and 80 TWh in 2020.

    Full Text Available The article analyzes the influence of natural monopolies on the value of residential property, discusses the basic energy resources affecting it. Oil is defined as the main energy resource, its main brands, and their features are considered. The different authors’ perspectives of the impact of oil prices on the real estate prices are considered (“no effect”, “direct effect” and “indirect effect”. Schemes (models, clearly demonstrating the cause-and-effect relations of the impact of prices of the main energy resources on each other and on the value of residential property, are provided. The stability of relations between the prices of the major energy recourses (between each other as well as between each resource and real estate prices and residential property prices in the primary market are analyzed. The interval of “crisis” and “crisis-free” time is defined. The impact of the energy in “crisis” and “crisis-free” time is analyzed. The impact of oil prices on the residential property prices is proved through the cement as the main price-determining element in the construction. The introduction of the state target compensation allowing to increase the availability of residential property is proposed as one of the elements of a comprehensive solution of the “housing question”. The size of the state target compensation in absolute (in rubles and relative (% prices for residential real estate values is determined, taking into account the sufficient reproduction of the population, and restrictions on the right to use it are introduced. The total value of the state target compensation per total number of homebuyers is calculated, and its share in the expenditures of the consolidated budget and budgets of state extra-budgetary funds is determined. The realization of the state target compensation based on an average annual growth among the major countries of the world is grounded.

    The European Committee for Standardization (CEN) through its Technical Committee CEN/TC-350 is developing a series of standards for assessing the building sustainability, at both product and building levels. The practical application of the selection (decision making) of structural alternatives made by one-way slabs leads to an intermediate level between the product and the building. Thus the present study addresses this problem of decision making, following the CEN guidelines and incorporating relevant aspects of architectural design into residential construction. A life cycle assessment (LCA) is developed in order to obtain valid information for the decision making process (the LCA was developed applying CML methodology although Ecoindicator99 was used in order to facilitate the comparison of the values); this information (the carbon footprint values) is contrasted with other databases and with the information from the Environmental Product Declaration (EPD) of one of the lightening materials (expanded polystyrene), in order to validate the results. Solutions of different column disposition and geometries are evaluated in the three pillars of sustainable construction on residential construction: social, economic and environmental. The quantitative analysis of the variables used in this study enables and facilitates an objective comparison in the design stage by a responsible technician; the application of the proposed methodology reduces the possible solutions to be evaluated by the expert to 12.22% of the options in the case of low values of the column index and to 26.67% for the highest values. - Highlights: • Methodology for selection of structural alternatives in buildings with one-way slabs • Adapted to CEN guidelines (CEN/TC-350) for assessing the building sustainability • LCA is developed in order to obtain valid information for the decision making process. • Results validated comparing carbon footprint, databases and Env.

    Construction activity in Europe has increased substantially in the past decade. Likewise, there has also been a commensurate rise in the generation of construction and demolition waste (C&DW). This, together with the fact that in many European countries the rate of recycling and reuse of C&DW is still quite low has engendered a serious environmental problem and a motivation to develop strategies and management plans to solve it. Due to its composition, there is a significant potential to reuse and/or recycle C&DW, and thereby, contribute to improving the sustainability of construction and development, but practical procedures are not yet widely known or practiced in the construction industry. This article (a) summarizes the different applications that are presently practiced to optimize the recovery and/or application of C&DW for reuse, and (b) proposes various measures and strategies to improve the processing of this waste. The authors suggest that to enhance environmental effectiveness, a conscious and comprehensive C&DW management plan should be implemented in each jurisdiction. More precisely, this study presents a holistic approach towards C&DW management, through which environmental benefits can be achieved through the application of new construction methods that can contribute to sustainable growth.

    , Assessment and Review of Information package. As both reviewers were in agreement on all studies included, a third reviewer was not required. A final total of eight papers, qualitative in nature, were included in the review. The majority of papers examined the experiences of nurses' leadership styles and the management characteristics within their organisations. The qualitative papers were analysed using The Joanna Briggs Institute-Qualitative Assessment and Review Instrument.The process of meta-synthesis embodied in this programme involves the aggregation or synthesis of findings or conclusions. Five syntheses were derived with key themes related to education, professional nursing development, positive attitudes to aged care and the need for a supportive environment. Nurses that work in the aged care environment show a strong motivation to work in care and provide the best outcomes in nursing the elderly. Geriatric nursing is considered a specialised and complex area of healthcare by the nursing profession. Nurses experience a lack of professional support and collaboration from allied health and medical colleagues. There is a lack of specific education that is focused in clinical leadership and health team management. There is no current structured pathway of learning and development for nursing careers in aged care. Nurses identify with their leadership role in residential aged care, and experience paradoxical feelings of being valued by the clients and devalued by the system at the same time. Organisational barriers are strong in preventing continuing education and skills development for nurse leaders in aged care environments. Overall the themes presented in the review reported the negative experiences of nurses in residential aged care and geriatrics. Nurses will continue to be devalued if there is no professional identity and support for their roles and need to have a career pathway when making the decision to enter into aged and geriatric practice.

    Although the significant scientific advances on place attachment literature, no instruments exist specifically developed or adapted to residential care. 410 adolescents (11 - 18 years old) participated in this study. The place attachment scale evaluates five dimensions: Place identity, Place dependence, Institutional bonding, Caregivers bonding and Friend bonding. Data analysis included descriptive statistics, content validity, construct validity (Confirmatory Factor Analysis), concurrent validity with correlations with satisfaction with life and with institution, and reliability evidences. The relationship with individual characteristics and placement length was also verified. Content validity analysis revealed that more than half of the panellists perceive all the items as relevant to assess the construct in residential care. The structure with five dimensions revealed good fit statistics and concurrent validity evidences were found, with significant correlations with satisfaction with life and with the institution. Acceptable values of internal consistence and specific gender differences were found. The preliminary psychometric properties of this scale suggest it potential to be used with youth in care.

    Full Text Available This paper analyzes the different roots of current residential high-rise clusters emerging in new city districts along the coast of Bahrain’s capital city Manama, and the resulting urban planning and design challenges. Since the local real-estate markets were liberalized in Bahrain in 2003, the population grew rapidly to more than one million inhabitants. Consequently, the housing demand increased rapidly due to extensive immigration. Many residential developments were however constructed for the upper spectrum of the real-estate market, due to speculative tendencies causing a raise in land value. The emerging high-rise clusters are developed along the various waterfronts of Manama on newly reclaimed land. This paper explores the spatial consequences of the recent boom in construction boom and the various challenges for architects and urban planners to enhance urban qualities.

    The public will play a vital role in shaping the future of the drone sector. The sector’s fate is tied to factors such as the capacity to serve the public and convince it that drones can benefit society, the ability to ensure that drones are used in a safe and considerate manner, and the readiness...... and effectiveness of the sector to address public concerns, such as safety and privacy. This report addresses public reactions to drones in residential and public settings and the concerns they raised. We present the results of two studies conducted as part of a collaborative project between the University...... of Southern Denmark (SDU), Aalborg University (AAU) and the Danish Transport, Construction and Housing Authority. The report builds upon and supplements the research conducted in the initial phase of the project (Bajde et al. 2017)....

    This paper reports an investigated result of residential radon concentration in Jingchuan County, Gansu Province, during May 2004 to November 2006. Alpha track detectors were used to measure radon level. Construction types of house and percentages of residents living in the county were also investigated through questionnaires. The result showed that the mean radon concentration in 62 investigated houses was 96.2 Bq·m -3 . The radon concentration in cave dwelling was the highest among all type of dwellings. The average level in cave dwelling is 110.2 Bq·m -3 , which was significantly higher than the national mean value published in literatures, and exceed the WHO recommended value of 100 Bq·m -3 . A considerable number of rural residents are living in cave dwellings in Jingchuan County. Attention should be paid to the radon problem and some proper protection measures taken. (authors)

    The space heating demand of residential buildings can be decreased by improved insulation, reduced air leakage and by heat recovery from ventilation air. However, these measures result in an increased use of materials. As the energy for building operation decreases, the relative importance of the energy used in the production phase increases and influences optimization aimed at minimizing the life cycle energy use. The life cycle primary energy use of buildings also depends on the energy supply systems. In this work we analyse primary energy use and CO{sub 2} emission for the production and operation of conventional and low-energy residential buildings. Different types of energy supply systems are included in the analysis. We show that for a conventional and a low-energy building the primary energy use for production can be up to 45% and 60%, respectively, of the total, depending on the energy supply system, and with larger variations for conventional buildings. The primary energy used and the CO{sub 2} emission resulting from production are lower for wood-framed constructions than for concrete-framed constructions. The primary energy use and the CO{sub 2} emission depend strongly on the energy supply, for both conventional and low-energy buildings. For example, a single-family house from the 1970s heated with biomass-based district heating with cogeneration has 70% lower operational primary energy use than if heated with fuel-based electricity. The specific primary energy use with district heating was 40% lower than that of an electrically heated passive row house. (author)
