The significance of owner participation for a successful detached housing development in Malaysia

The detached housing scheme is a unique and exclusive segment of the residential property market in Malaysia. Generally, the product is expensive and for many Malaysians who can afford them, owning a detached house is a once in a lifetime opportunity. In spite of this, most of the owners failed to fully comprehend the specific need of this type of housing scheme, increasing the risk of it being a problematic undertaking. Unlike other types of pre-designed "mass housing" schemes, the detached housing scheme may be built specifically to cater the needs and demands of its owner. Therefore, owner participation during critical development stages is vital to guarantee the success of the development as a whole. In addition, due to its unique design the house would have to individually comply with the requirements and regulations of relevant authorities. Failure by the owner to recognise this will result in delays, penalties, disputes and ultimately cost overruns. These circumstances highlight the need for a research to guide the owner through participation during the critical development stages of a detached house. Therefore, this research aims to develop a guideline to improve owner participation for a successful detached house development in Malaysia. To achieve the aim, questionnaire surveys and semi-structured interviews were employed to collect the detached house owners' and consultants' & contractors' responses through their experiences in developing detached houses in Malaysia. Stratified and random sampling were utilised to gather information from both parties to represent Malaysian detached house participants. The questionnaire responses were analysed through the application of quantitative analysis such as descriptive analysis, factor analysis and structural equation modelling which were substantiated through qualitative analysis procedure such as content analysis. This research had identified that in order to produce a successful outcome detached house owners are required to participate during critical stages of the development. In the planning stage, the owner needs to provide proper specific input to the consultant regarding his/her expectations of the cost for the entire development, its detailed specification and general idea of the internal and external design of the detached house and its compound. In the contracting stage, the owner must make the appropriate choice of selecting the right contractor for the job. This decision may be taken after recommendations from the consultants or from the owner's personal contacts or experiences but it is not recommended for the owner to select a contractor primarily on the basis of the lowest bid. In the completion stage, the owner may need to attend a number of important site meetings to ensure that the progress of the works is according to what had been planned and the completion date is achievable. By having the owners undertake an active role during critical stages of the development, not only the quality and delivery of the development improved but also there is an increase in satisfaction to the owners themselves.

The importance of reporting housing and husbandry in rat research

In 1963, the National Institutes of Health (NIH) first issued guidelines for animal housing and husbandry. The most recent 2010 revision emphasizes animal care “in ways judged to be scientifically, technically, and humanely appropriate” (National Institutes of Health, 2010, p. XIII). The goal of these guidelines is to ensure humanitarian treatment of animals and to optimize the quality of research. Although these animal care guidelines cover a substantial amount of information regarding animal housing and husbandry, researchers generally do not report all these variables (see Table ​Table1).1). The importance of housing and husbandry conditions with respect to standardization across different research laboratories has been debated previously (Crabbe et al., 1999; Van Der Staay and Steckler, 2002; Wahlsten et al., 2003; Wolfer et al., 2004; Van Der Staay, 2006; Richter et al., 2010, 2011). This paper focuses on several animal husbandry and housing issues that are particularly relevant to stress responses in rats, including transportation, handling, cage changing, housing conditions, light levels and the light–dark cycle. We argue that these key animal housing and husbandry variables should be reported in greater detail in an effort to raise awareness about extraneous experimental variables, especially those that have the potential to interact with the stress response.

Wind-resistant low-rise buildings in the tropics

High-wind events such as storms and hurricanes cause severe damage to low-rise building (housing, schools, and industrial, commercial, and farm buildings). Roof claddings often suffer the worst, which then leads to accelerated damage to the whole building. Australia leads the way in solving this international problem through extensive research and development work, and has adequate documents in place. This paper first illustrates briefly the nature of high-wind events and then the commonly observed damage to buildings. Australian research work and design practice are then described, based on which suitable design recommendations for wind-resistant buildings are presented.

Saudi Arabia’s sustainable housing limitations : the experts’ views

Purpose The purpose of this paper is to attempt to bridge the gap between sustainable housing and the use of smart technologies to improve the level of sustainability in the housing construction in Saudi Arabia, by discussing the barriers and enablers concerned with applying sustainability to housing construction in Saudi Arabia, which utilises smart technologies. Design/methodology/approach A Delphi method survey was employed, for which 25 individuals from three key stakeholder groups of the Saudi housing sector participated. They were asked about their degree of agreement (or disagreement) about the various barriers and enablers of applying sustainability to housing construction in Saudi Arabia, which utilises smart technologies. This research paper must be considered as an indicative study of selected experts that do not represent in any way the total population of Saudi Arabia. Findings Lack of public awareness has been identified as the most significant barrier in implementing sustainable housing development in Saudi Arabia, which utilises smart technologies. Raising awareness of the public to the benefits of sustainable housing and enlightening key project stakeholders in the design of sustainable housing are both essential in order to overcome the barriers discussed in this paper. In addition, it is important to adopt smart sustainable construction methods, exemplified by but not limited to, appropriate water preservation and wastewater treatment systems that are simultaneously smart and sustainable. Research limitations/implications This particular research has dealt with only barriers and enablers in the application of sustainability to housing in Saudi Arabia, which utilises smart technologies. For a more complete understanding, there is a need for further analysis of supplementary factors. Practical implications A study such as this, which identifies and prioritises barriers and enablers, could prove useful in guiding or encouraging the relevant ministry in Saudi Arabia to develop policies founded in the implementation of sustainability to the housing sector. Originality/value This research is a preliminary investigation into the implementation of sustainable housing development as it relates to Saudi Arabia.

Does sustainable housing construction provide the home owner with a greater investment return?

Over the past 20 years there has been a considerable push at all three tiers of Government and private industry in Australia to improve the energy efficiency and sustainability levels of residential housing. A number of these initiatives have been voluntary, such as solar power and solar heating rebates, with other mandatory measures being incorporated into building standards and codes. Although the importance of energy efficiency and sustainable materials have been widely conveyed both at the academic and public level, it does not always reflect in the residential house purchase decision by typical house buyers, including residential property investors. This paper will analyse a range of housing markets in Brisbane to determine the investment performance of those markets over the past 3 years to determine any significant differences between new residential suburbs and older residential suburbs where houses have not been constructed to the current energy efficiency and sustainability guidelines. The range of suburbs to be analysed will focus on middle to lower high value suburbs, with a particular focus on residential housing in Master Planned Communities to determine if socio-economic factors and development size and scope have an impact of the purchase and investment performance of sustainable houses in comparison to older housing stock. The paper confirms that the residential property market shows a higher capital return for residential property built under stricter sustainability guidelines than similar located and type of property built prior to the BCA 2004 and older style project type homes erected prior to 2000.

Data requirements of hedonic models in determining the impact of infrastructure charges on new housing costs

The use of hedonic models to estimate the effects of various factors on house prices is well established. This paper examines a number of international hedonic house price models that seek to quantify the effect of infrastructure charges on new house prices. This work is an important factor in the housing affordability debate, with many governments in high growth areas having user-pays infrastructure charging policies operating in tandem with housing affordability objectives, with no empirical evidence on the impact of one on the other. This research finds there is little consistency between existing models and the data sets utilised. Specification appears dependent upon data availability rather than sound theoretical grounding. This may lead to a lack of external validity with model specification dependent upon data availability rather than sound theoretical grounding.

Livable Housing Design : Who will take responsibility?

Current housing design and construction practices do not meet the needs of many people with disability and older people, and limits their inclusion and participation in community and family life. In spite of a decade of advocacy for regulation of access within residential environments, the Australian government has opted for a voluntary approach where the housing industry takes responsibility. Housing industry leaders have indicated that they are willing to transform their established practice, if it makes good business to do so, and if there is a demand from home buyers. To date, there has been minimal demand. In 2010, housing industry and community leaders formalised this commitment in an agreement, called Livable Housing Design, to transform housing design and construction practices, with a target of all new housing providing minimal access by 2020. This paper reports on a study which examined the assumption behind Livable Housing Design agreement; that is, individuals in the housing industry will respond voluntarily and take responsibility for the provision of inclusive housing. From interviews with developers, designers and builders in Brisbane, Queensland, the study found a complex picture of competing demands and responsibilities. Instead of changing their design and construction practices voluntarily to meet the future needs of users over the life of housing, they are more likely to focus on their immediate contractual obligations and to maintain the status quo. Contrary to the view of the government and industry leaders, participants identified that an external regulatory framework would be required if Livable Housing Design’s 2020 goal was to be met.

Purification of particles of subterranean clover red leaf virus using an industrial-grade cellulase

Particles of two isolates of subterranean clover red leaf virus were purified by a method in which infected plant tissue was digested with an industrial-grade cellulase, Celluclast® 2.0 L type X. The yields of virus particles using this enzyme were comparable with those obtained using either of two laboratory-grade cellulases, Cellulase type 1 (Sigma) and Driselase®. However, the specific infectivity or aphid transmissibility of the particles purified using Celluclast® was 10-100 times greater than those of preparations obtained using laboratory-grade cellulases or no enzyme. The main advantage of using Celluclast® is that at present in Australia its cost is only ca. 1% of laboratory-grade cellulases.

The link between infrastructure charges and housing affordability in Australia: Where is the empirical evidence?

Developer paid charges or contributions are a commonly used infrastructure funding mechanism for local governments. However, developers claim that these costs are merely passed on to home buyers, with adverse effects to housing affordability. Despite a plethora of government reports and industry advocacy, there remains no empirical evidence in Australia to confirm or quantify this passing on effect to home buyers and hence no data for which governments to base policy decision upon. This paper examines the question of who really pays for urban infrastructure and the impact of infrastructure charges on housing affordability. It presents the findings of a number of international empirical studies that provide evidence that infrastructure charges do increase house prices. Based on international findings, and in the absence of any Australian research, then these findings suggest that if the international findings are transferable, then there is empirical evidence to support the proposition that developer paid infrastructure charges are a significant contributor to increasing house prices.

Supermarkets and agro-industrial foods : the strategic manufacturing of consumer trust

There is increasing evidence of a weakened platform of consumer trust in mass produced food products. The resistance shown by consumers to the agro-industrial paradigm is evident in an emergent phase of reflexive consumerism, public reactions to an overly-concentrated retail sector and the rise of alternative food networks such as farmers' markets and organic box schemes. Supermarkets are responding strategically by aiming to manufacture new trust relations with consumers. This paper identifies three key strategies of trust manufacturing: (i) reputational enhancement though the institution of “behind the scenes,” business-to-business private standards; (ii) direct quality claims via private standard certification badges on food products, and ; (iii) discursive claimsmaking through symbolic representations of “authenticity” and “tradition.” Drawing upon the food governance literature and a “visual sociology” of supermarkets and supermarket produce, we highlight how trust is both commoditized and increasingly embedded into the marketing of mass-produced foods.

Provotypes: Teasing out tensions between industrial context and use context

What industrial organisations think people do and what they actually do are often two very different things. But exactly this tension can be a source of innovation: how can we give form to insights about what people do, to deliberately challenge industries' conceptions, and inspire new product and service development

Ethnography of software maintenance activities in an industrial engineering setup

New technical and procedural interventions are less likely to be adopted in industry, unless they are smoothly integrated into the existing practices of professionals. In this paper, we provide a case study of the use of ethnographic methods for studying software bug-fixing activities at an industrial engineering conglomerate. We aimed at getting an in-depth understanding of software developers' everyday practices in bug-fixing related projects and in turn inform the design of novel productivity tools. The use of ethnography has allowed us to look at the social side of software maintenance practices. In this paper, we highlight: 1) organizational issues that influence bug-fixing activities; 2) social role of bug tracking systems, and; 3) social issues specific to different phases of bug-fixing activities.
