The purpose of this study is to highlight and demonstrate how the study of stress and related responses in construction can best be measured and benchmarked effectively.

A range of perceptual and physiological measures are obtained across different time periods and during different activities in a fieldwork setting. Differences in the empirical results are analysed and implications for future studies of stress discussed.

The results of this study strongly support the use of multiple psychometrics and biosensors whenever biometrics are included in the study of stress. Perceptual, physiological and environmental factors are all shown to act in concert to impact stress. Strong conclusions on the potential drivers of stress should then only be considered when consistent results apply across multiple metrics, time periods and activities.

Stress is an incredibly complex condition. This study demonstrates why many current applications of biosensors to study stress in construction are not up to the task and provides empirical evidence on how future studies can be significantly improved.

To the best of the author’s knowledge, this is the first study to focus explicitly on demonstrating the need for multiple research instruments and settings when studying stress or related conditions in construction.

This paper is a proposal to provide for the poor – those earning insufficient incomes to satisfy their needs and the unemployed – by enabling them to acquire dividend-paying (and voting) shares in the companies that produce the goods and services consumed in society. It will be accomplished by: (1) establishing a mortgage loan at birth for every newborn child; (2) the loans will be taken out by each of the major producing companies (plus start-ups) in the names of the children as firms do their annual planning; (3) the amount of the loan will be increased annually when the companies plan for succeeding years; (4) a portfolio of new assets – stocks and bonds – in the companies will be purchased with the funds from the mortgage loan; (5) the loan will be repaid over a period of years from the dividends paid by the companies. Once redeemed, the assets, and their future earnings, will belong to the person in whose name the mortgage loan was established. Should the program include all newborns, rich and poor in the name of fairness, when today's cohort reaches maturity, every member of society will be a shareholder in a variety of wealth producing companies that pay regular dividends. The proposal will not require funds from the government and no additional taxes will have to be raised.
