Strategies for reducing employee turnover and increasing retention rates of quantity surveyors

Quantity surveyors (QS) play an important role in the construction industry. There is therefore a need to reduce their job turnover, by minimizing their intention to quit the job (turnover intention) and improving their job satisfaction. Turnover intention was operationalized as the number of years QS are likely to remain in the profession (Y1) and in their present firms (Y2). The aims are to investigate job and jobholder characteristics that significantly affect Y1 and Y2; and provide recommendations to reduce QS’ turnover intentions. Using questionnaire survey, data were collected via e-mail from randomly selected QS in Singapore. Correlation analysis revealed that to reduce turnover, QS should be given competitive monetary and non-monetary benefits, and autonomy in decision making. To reverse turnover intention of well-performing QS who are ensconced in their firms, firms could enrich QS’ jobs so that their growth needs are met and they feel a sense of accomplishment. Certain characteristics of QS and their jobs give rise to job satisfaction, and therefore designing quantity surveying jobs that take in these characteristics may decrease turnover intention. The relevant characteristics that should be included in the design of QS’ jobs to increase retention rates are task significance, autonomy and feedback.     

What’s in a (Migrant) House? Changing Domestic Spaces,the Negotiation of Belonging and Home-making in Ecuadorian Migration

Migrants’ constructions of their domestic spaces, and their struggle to feel at home in both receiving and sending societies, are an emerging focus of research in migration studies. Housing issues are also a privileged observatory on their transnational social engagement, as well as on the changing boundaries of their membership and belonging. This article addresses the everyday bases of their home-making and house-building practices, drawing on a multi-sited ethnography of Ecuadorian migration to Italy. What can be inferred from the ways in which migrants inhabit their houses “here”, while typically investing in better housing arrangements “there”, as to their alignment towards either society? What do their housing-related practises suggest about the potential to feel locally and transnationally at home, given the structural constraints they are subject to? By tracing the meanings, enactments and locations of migrants’ home, I aim to advance the debate on home and migration in two respects: the persistent materiality which underlies the home experience, and the significance of migrants’ houses, particularly in sending societies, as a window on the mixed social consequences of migration.

Homebuyer choices and search behaviour in a distressed urban setting

Buyers purchase homes in Cleveland, Ohio, because visible neighbourhood qualities, structural attributes and neighbourhood amenities are appealing. How they perceive their housing and their neighbourhoods tends to vary with income, education, previous tenure and their type of employment. Their perceptions are confounded, however, by their race, the presence of school age children, their previous place of residence, work location and time expected to reside in the house. Neighbourhood familiarity and locational convenience are also key components in the homebuyer's decision process. Moreover, few higher income homebuyers anticipate remaining in their homes for more than four years. Because their work orientation is outside the downtown, future housing purchases may similarly occur outside the city. To the extent that there is a slackening in the purchasing of housing units in the central city by higher income households, housing market and neighbourhood stability are likely to deteriorate.     

Preservation initiatives for the truncated pyramid-shaped traditional housesof Siirt,Turkey

The traditional houses of the residential areas in and around Siirt in the southeastern region of Turkey are notable because of their interesting forms. The most successful examples are the "truncated pyramidal-shaped houses" that have existed for centuries and are unique to the locality; however, these forms are demolished rapidly. In this study, the structures of small- scale settlements in Siirt province and its environs have been evaluated to highlight the cultural aspects of the region. The subject of this research is to investigate the design principles of the rural houses constructed in vernacular style to raise international awareness of the need to preserve vernacular architecture. Surviving examples have been examined in terms of multiple case approach by their forms, spatial compositions, changes in their forms over time, their layouts in urban and rural areas, the construction techniques used to produce them from material production through implementation, the composition of the living space and its uses, their differences or similarities to other houses in the region and their aesthetic details. The research reveals that the design principles of traditional rural architecture offer the use of local material and techniques in a unique way that promote highlights to the future.

The pleistocene clastic deposits of the latium coast—Italy

Close to the present Latium coast, at Rio Torto, in the area between Pomezia and Ardea, about 35 km to the South of Rome, there are vast sandy deposits of continental and marine origin that may be associated with ancient coast lines. The extent and thickness of these deposits vary widely and are used as sources for extracting aggregate materials that are successfully used in preparing cement mortars. Field surveys and laboratory tests have helped identify these products as belonging to a paleogeographic environment and to define both their volume and their geographic location. The results obtained have allowed characterization of the sands from a technical point of view and to define their fields of utilization keeping account of their location and their mining availability.     

Why do Displaced Residents Move to Socioeconomically Disadvantaged Neighbourhoods?

Urban restructuring—the large-scale demolition of low-rent dwellings, followed by the construction of more upmarket alternatives—forces residents to make a step in their housing career. Because displaced residents tend to have a low socioeconomic position, they are often confined to the most affordable parts of the housing stock. Since these dwellings are generally concentrated in socioeconomically disadvantaged neighbourhoods, displaced residents are likely to move to such neighbourhoods. However, they do have a measure of freedom to choose their new neighbourhood. This article reveals which kinds of households move to disadvantaged neighbourhoods and why they do so. An analysis of both quantitative and qualitative data collected in five Dutch cities shows that not only displaced households' restrictions but also their preferences are crucial to understand their relocation choices.     

Survey of construction lawyers' attitudes and practice in the use of ADR in contractors' disputes

Continuing a survey of contractors' perceptions about alternative dispute resolution (ADR) this paper seeks to report an investigation of the level of involvement of legal advisors to the construction industry in the dispute resolution process and the perceptions that legal professionals have about the use of ADR in construction disputes. The research findings are that contractors are likely to involve lawyers in the dispute resolution procedure, particularly when disputes concern a legal issue, when the parties to the dispute are entrenched in their argument, or when the other party insists on using legal professional assistance. In these defined circumstances, legal advisors will be influential in determining the potential use of ADR. The paper concludes that lawyers are unlikely to recommend ADR for most disputes between contractors, particularly if the dispute resolution process is perceived to involve the use of delay by main contractors, if the parties are fixed in their arguments or if they are exhibiting adversarial behaviour in their approach to the dispute. In these circumstances lawyers and their clients prefer the force of the formal systems over conciliatory ADR procedures.     

Polybrominated diphenyl ether (PBDE) flame retardants

Polybrominated diphenyl ether, PBDE, flame retardants are now a world-wide pollution problem reaching even remote areas. They have been found to bioaccumulate and there are concerns over the health effects of exposure to PBDEs, they also have potential endocrine disrupting properties. They are lipophilic compounds so are easily removed from the aqueous environment and are predicted to sorb onto sediments and particulate matter or to fatty tissue, aiding their distribution throughout the environment. PBDEs are structurally similar to PCBs and DDT and, therefore, their chemical properties, persistence and distribution in the environment follow similar patterns. Concentrations of PBDEs found in environmental samples are now higher than those of PCBs. Evidence to date demonstrates that PBDEs are a growing problem in the environment and concern over their fate and effects is warranted. The manufacture of reactive and additive flame retardants is briefly discussed and their fate and behaviour in the environment is assessed. PBDE toxicology is reviewed and methods of analysis are evaluated.
