Purpose – This experimental economics study using brain imaging techniques investigates the risk-ambiguity distinction in relation to the source preference hypothesis (Fox & Tversky, 1995) in which identically distributed risks arising from different sources of uncertainty may engender distinct preferences for the same decision maker, contrary to classical economic thinking. The use of brain imaging enables sharper testing of the implications of different models of decision-making including Chew and Sagi's (2008) axiomatization of source preference.

Methodology/approach – Using fMRI, brain activations were observed when subjects make 48 sequential binary choices among even-chance lotteries based on whether the trailing digits of a number of stock prices at market closing would be odd or even. Subsequently, subjects rate familiarity of the stock symbols.

Findings – When contrasting brain activation from more familiar sources with those from less familiar ones, regions appearing to be more active include the putamen, medial frontal cortex, and superior temporal gyrus. ROI analysis showed that the activation patterns in the familiar–unfamiliar and unfamiliar–familiar contrasts are similar to those in the risk–ambiguity and ambiguity–risk contrasts reported by Hsu et al. (2005). This supports the conjecture that the risk-ambiguity distinction can be subsumed by the source preference hypothesis.

Research limitations/implications – Our odd–even design has the advantage of inducing the same “unambiguous” probability of half for each subject in each binary comparison. Our finding supports the implications of the Chew–Sagi model and rejects models based on global probabilistic sophistication, including rank-dependent models derived from non-additive probabilities, e.g., Choquet expected utility and cumulative prospect theory, as well as those based on multiple priors, e.g., α-maxmin. The finding in Hsu et al. (2005) that orbitofrontal cortex lesion patients display neither ambiguity aversion nor risk aversion offers further support to the Chew–Sagi model. Our finding also supports the Levy et al. (2007) contention of a single valuation system encompassing risk and ambiguity aversion.

Originality/value of chapter – This is the first neuroimaging study of the source preference hypothesis using a design which can discriminate among decision models ranging from risk-based ones to those relying on multiple priors.

This paper analyses the role of Lee Kuan Yew, Singapore’s first prime minister from June 1959 to November 1990, in minimising corruption by implementing a zero-tolerance policy toward corruption in Singapore.

This paper is based on the analysis of Lee’s beliefs and the policies he introduced to curb corruption in Singapore.

Lee’s disdain for corruption and his beliefs in meritocracy and the importance of good leadership shaped his commitment to a zero-tolerance policy against corruption, which was enforced impartially and sustained in Singapore for the past 62 years.

This analysis of how Lee transformed Singapore into one of the least corrupt countries in the world would be of interest to policy-makers, practitioners and scholars concerned with minimising corruption in their own countries.

The aim of this paper is to appreciate the difficulties faced by small and medium enterprises (SMEs) in a small open economy such as Singapore where there is very little margin for comfort.

The approach is analytical and statistical. Comparing key ratios over time to reinforce the findings is done.

SMEs in Singapore are price‐takers in the product markets and they are also price‐takers in the input markets. When there is substantial increase in costs, SMEs will be in trouble as they cannot pass the increased costs to the buyers of their products and services.

The implication is that only the government can help SMEs. With more information, the government can be convinced that SMEs can play a big role in the economy.

The paper shows that government and the SMEs' association can find ways to help SMEs.

Nanostructured titanium dioxide (TiO₂) coatings can potentially address the current surge in façade cleaning cost, maintenance and labour problems. The purpose of this paper is to investigate potential maintainability issues and design challenges concerning the effective performance of TiO₂ façade coatings’ hydrophilic properties, especially in tropical environments such as Singapore. This paper aims to establish a list of green maintainability design criteria to help minimise future TiO₂ façade coating issues when this coating is applied on commercial buildings with concrete and stonemasonry façade materials.

A mixed-mode approach that includes a literature review, site investigation, instrumental case studies and expert interviews is used in this study.

TiO₂ coatings help improve façade performance whilst offering environmental benefits to society. This study reports that green maintainability design criteria are vital requirements in designing sustainable buildings at the outset. The identified defects and issues will aid in ensuring the effectiveness of TiO₂ application in building façades.

This study acts as a foundation for future researchers to strengthen this little researched area, serves as a useful guide in preventing possible TiO₂ coating issues and promotes industry awareness of the use of TiO₂ façade coatings.

Through an empirical study, this research proposes a multi-dimensional assessment method for Sustainable Building Design (SBD). This approach is adopted to investigate and evaluate the current practices of SBD and to provide a basis for refining such processes while reducing existing shortfalls. In doing so, a holistic sustainable framework for rating the sustainable performance of buildings is proposed.

To achieve the aforementioned purpose, this research (1) investigates the most current trends in SBD including the use of Building Information Modelling (BIM); (2) examines the practical issues of SBD; (3) proposes a multi-dimensional assessment method; and (4) compares 18 separate case studies in the three countries of Australia, United Kingdom and USA, as part of the SBD implementation. To compare these case studies, an additional SBD tool, Green Building Rating and Certification System (GBELS) was carefully selected and applied. Five core values of SBD were identified based on functionality, accessibility and productivity, which align with the GBELS outcomes.

This research found that, for the 18 examined buildings, the main issues in SBD in the three countries concerned environmental and ecological issues. These included the impacts of buildings on the environment, as well as issues concerning the buildings' life cycle analysis and assessment. It was also determined that energy usage, pollution reduction and climate change concerns were important inclusions in establishing these buildings, particularly in the USA.

To support the research aim, this paper explores the most innovative trends in SBD assessments including their Structural Health Monitoring (SHM), grade (stars) classification, Relative Weight (RW) and particularly GBELS. GBELS was selected for this research, since it is relatively new and there is little available literature discussing its adaptation. Accordingly, this research further evaluates the application of GBELS as a part of versatility in SBD multi-dimensional assessment method. As the basis of these tests, a total of 18 separate case studies are closely evaluated.

To provide a structured and integrated framework of corporate strategy in order to help practitioners and researchers identify critical issues related to the Chinese construction industry and analyze its dynamics from a holistic viewpoint.

A brief review of the major themes of strategy mostly developed by western researchers is first presented. This is then supplemented by a review of the pertinent characteristics of the construction industry in general, and those related to China's context in specific, which affect management decision‐making. Two case studies are used to illustrate the concepts implied by the proposed framework.

The cases of Guangsha and the Shanghai Construction Group demonstrate that there is no hard and fast rule in developing a coherent strategy. This is even truer considering the fact that China's circumstances are still evolving.

The critical elements identified in the proposed framework serve as a good starting point for individual firms to further develop a more detailed execution plan.

This paper bridges a management gap that exists between mainstream management researchers, who have few precedence of studying the construction industry, and traditional construction management researchers, who tend to focus on project‐level issues rather than corporate‐level issues.

The purpose of this paper is to examine a series of environmental factors and industrial conditions governing the construction industry in China. The outcome of this part of the analysis sheds light on the development of appropriate competitive strategies and important resources and competencies (IRCs) to establish long‐term competitive advantages.

The overarching conceptual framework consists of both external and internal analyses. Since, the scope of work is very broad, the materials presented in this paper is limited to external analysis of environmental factors. The study is primarily derived from a literature review and synthesis of data gathered from various public sources. Certain parts of the analysis utilize frameworks developed by other researchers and selective statistical methods.

Some environmental factors, such as government intervention and legal and regulatory systems require the development of Guanxi (relationships) to cope with. Other factors including market structure, project procurement systems, horizontal market segments related to construction, regional characteristics and upstream and downstream functions within the construction value chain are suggestive of five potential types of competitive strategies: cost leadership, differentiation, market/product diversification, geographical diversification, and vertical/functional integration.

The research study as a whole is targeted at large construction firms in China that belong to the First class qualification category. Therefore, the proposed competitive strategies and IRCs may not be applicable to small and medium construction enterprises.

Application of strategic management theories and empirical findings related to the Chinese construction industry is lacking. This research fills this gap and builds a foundation for future studies related to this industry.

The purpose of this paper is to investigate the hardness and elastic modulus on interfacial phases formed between Sn-3.5Ag solder and Ni-18 at. % W alloy film by nanoindentation. It has been found that a ternary amorphous Sn-Ni-W layer formed below Ni3Sn4 IMC at the interface. In this study, mechanical properties of the IMC formed between SA solder and Ni-18 at. % W film after six times reflows were performed by nanoindentation.

The characterization was carried at 25°C, and 100 indents were generated. The elastic modulus and hardness were investigated.

The results showed that hardness of Ni3Sn4 IMC was higher than amorphous Sn-Ni-W phase. A slight bigger indent was observed on the Sn-Ni-W layer compared with that on the Ni3Sn4 IMC. Lower topographical height in the Sn-Ni-W layer indicated that the Sn-Ni-W phase was softer compared with the Ni3Sn4 IMC. The lower hardness and soft Sn-Ni-W phase is significantly related to the amorphous structure that formed through solid-state amorphization.

There are no publications about the indentation on the interfacial between the Ni-W layer and the Sn-Ag solder.

Rapid prototypes formed using stereolithography (SL) method have to undergo post‐curing to increase their strength and rigidity. This study attempts to reduce, if not eliminate, post‐cure distortion by characterising curing behaviours. Curing (both heat and UV initiated) characteristics of an acrylic‐based photopolymer under actual fabrication conditions were studied using Raman spectroscopy as well as differential scanning calorimetry (DSC) and differential scanning photo‐calorimetry (DSP). Specimens of single photopolymer lines were created using a SL machine. Raman spectroscopy was used to quantify the curing percentage at different areas on the cross‐section of these lines. Curing percentages before and after post‐curing were also obtained from the experiments. Difference in percentage of post‐curing gave an indication of the distortions faced. It was found that uncured and partially cured resins trapped within the photopolymer resulted in inhomogeneity of curing in the specimens causing shrinkage and distortion.
