With numerous and ambiguous sets of information and often conflicting requirements, construction management is a complex process involving much uncertainty. Decision makers may be challenged with satisfying multiple criteria using vague information. Fuzzy multi-criteria decision-making (FMCDM) provides an innovative approach for addressing complex problems featuring diverse decision makers’ interests, conflicting objectives and numerous but uncertain bits of information. FMCDM has therefore been widely applied in construction management. With the increase in information complexity, extensions of fuzzy set (FS) theory have been generated and adopted to improve its capacity to address this complexity. Examples include hesitant FSs (HFSs), intuitionistic FSs (IFSs) and type-2 FSs (T2FSs). This chapter introduces commonly used FMCDM methods, examines their applications in construction management and discusses trends in future research and application. The chapter first introduces the MCDM process as well as FS theory and its three main extensions, namely, HFSs, IFSs and T2FSs. The chapter then explores the linkage between FS theory and its extensions and MCDM approaches. In total, 17 FMCDM methods are reviewed and two FMCDM methods (i.e. T2FS-TOPSIS and T2FS-PROMETHEE) are further improved based on the literature. These 19 FMCDM methods with their corresponding applications in construction management are discussed in a systematic manner. This review and development of FS theory and its extensions should help both researchers and practitioners better understand and handle information uncertainty in complex decision problems.

Investigates urban bias in state policy making in Mexico. Refers to literature claiming that rural poverty in developing nations is a major problem because capitalism reflects an urban bias. Examines social security coverage for the rural poor in Mexico and notes that there are great variations depending on area, suggesting that social security coverage is politically negotiable. Outlines briefly the historical development of Mexico’s welfare state and uses a power resource model to demonstrate how groups with competing interests go about securing benefits from the state. Cites literature on dependency theory, indicating that rural groups have failed to mobilize politically and have therefore not secured the same state resources (such as social security benefits and housing) as urban groups, yet argues that this does not always apply in Mexico, partially due to party politics and bureaucratic paternalism. Explains how data was collected to examine regional variations in social security coverage among the rural poor and how the data was analysed. Reveal that workers in important international export markets (such as cotton and sugar) have greater political leverage in obtaining better social security benefits. Notes also that areas supporting the political party in power obtain better benefits. Concludes, therefore, that rural workers are not powerless in the face of urban capitalism and that urban bias and dependency theories do not reflect the situation in Mexico – rather social security benefits are politically negotiable.

This study investigates the impact of the enhanced continuous disclosure regime introduced in December 2002 on several measures of information risk in NZX‐listed stocks. We employ two microstructure models and an intraday data set to measure information risk in a sample of 71 stocks. Our empirical results show that the reforms enacted in December 2002 had no significant effect on either the level of information‐based trading or the adverse selection component of market spreads in our sample of NZX‐listed stocks.

The purpose of this paper is to study the effects of overload on the threshold stress intensity factor range (ΔK_th) in SUS316.

The fatigue tests are carried out to determine the resultant threshold stress intensity factor range (ΔK_th). The mechanism of the improvement of ΔK_th by the tensile overloading is analyzed using the Dugdale model.

It is clarified that the value of ΔK_th increases as increasing the overloading.

The apparent value of ΔK_th of stainless steel can be improved by a tensile overload, the fatigue strength of structural members that have a surface crack can be increased by a tensile overload.

As a result, the reliability and safety of structures, such as energy plants, can also be improved.

Voluntary changes in accounting principle represent explicit and fundamental decisions by managers to exercise accounting discretion. This paper develops an organizing framework to review prior literature on voluntary changes, provides descriptive insights on contemporary changes, and identifies opportunities for future research on voluntary changes. The voluntary change literature is robust and has examined many questions using data prior to the Sarbanes-Oxley Act of 2002 (SOX). We find that contemporary voluntary changes often vary across the pre-SOX, post-SOX, and post-SFAS No. 154 periods by the materiality of their income effect, issue type, and justifications provided by managers, suggesting that manager use of voluntary changes has evolved over time. Our future research opportunities consider potential determinants of voluntary changes including strategic incentives, environmental conditions, and manager characteristics, as well as the potential direct or moderating role of corporate governance and auditors on manager use of voluntary changes. They also consider user reactions to voluntary changes. By providing insight into both extant voluntary change research and the contemporary use of voluntary changes, our study informs standards setters who grant managers the ability to exercise this form of accounting discretion, as well as researchers who plan to study accounting choice through voluntary changes.
