Untangling rhetoric and reality in the CSR debate – the role of corporate social responsibility in effective business strategy

While there is a strong moral case for corporate social responsibility (CSR), the business case for CSR is certainly not irrefutable. A better understanding of how to integrate CSR into business strategy is needed but with ever increasing momentum towards sustainability as a business driver, it is often difficult to untangle the rhetoric from reality in the CSR debate. Through an analysis of eight case studies of leading firms from throughout the construction supply chain who claim to engage in CSR, we explore how consulting and contracting firms in the construction and engineering industries integrate CSR into their business strategy. Findings point to an inherent caution of moving beyond compliance and to a risk-averse culture which adopts very narrow definitions of success. We conclude that until this culture changes or the industry is forced by clients or regulation to change, the idea of CSR will continue to mean achieving economic measures of success, with ecological goals a second regulated priority and social goals a distant third

Does the built-environment industry attract risk-taking individuals?

This exploratory research examines whether or not those attracted to professional-level occupations in the built-environment industry are innately physical risk-takers and hence potentially, thereby, more likely to countenance or contribute to physically risky workplace climates. Using individual-level data, the occupational attractiveness of the built-environment industry subsectors of construction management and architecture are each found positively and significantly to be predicted by physical risk-taking propensity, but not by a comparator risk-taking propensity, gambling. Conversely, the occupational attractiveness of a comparator profession in financial services is found to be significantly predicted by gambling risk-taking propensity, but not by physical risk-taking propensity. Although exploratory, our finding that two key professions in the built-environment industry are each discretely found to be attractive to physical risk-takers suggests not only that constituent occupations within the industry, but that the industry as a whole might perhaps engender a self-reinforcing suboptimal workplace safety climate. Accordingly, constituent subsectors of the industry may need both separately and collectively to consider the phenomenon of physical risk-taking propensity amongst the professionals it attracts in order effectively to set and manage the site work-place safety climate that such professionals are ultimately responsible for creating and delivering in a sector fraught with physical risks for site workers

Predictors of construction time in detached housing projects

Building on previous literature on construction time performance (CTP), this study looks at the extent to which Gross Floor Area (GFA) and Number of Levels (NoL) are important factors in determining the construction time in Australian detached housing projects. Using a dataset of 196 comparable detached housing projects the results show that while GFA and NoL correlate strongly with estimated construction time, they correlated weakly with actual construction time. Dynamically changing events during construction appear to be the reason for the difference. Analyses indicate that cost variations brought about by Design changes, Site management errors; Site workmanship problems and Unforeseen site problems are significant factors in explaining the difference between actual and estimated construction time. Further, these factors affect larger housing projects (>400m2) more significantly than they do smaller projects (<350m2). It would therefore seem that even though GFA on its own has a poor correlation with actual construction time, this improves when teamed with the above cost variations. These results open up avenues for future research to look more closely at the effects of project dynamics (e.g. using causes of cost increases as a proxy) when predicting CTP, rather than relying too heavily on static variables like GFA or NoL. It is important that such variables are taken into account as a basis for teaching and promulgating an analytical basis to predicting construction time

Epidemiological analysis of typhoid fever in Kelantan from a retrieved registry

Aim: Despite the endemicity of typhoid in Kelantan, epidemiological data showing typhoid association to age, sex,ethnicity and district of patients is limited. This retrospective study investigated the statistical association of thesevariables from a retrieved registry.Methodology and results: Cross-tabulation using SPSS was used to analyze 1394 cases of confirmed typhoid patientsadmitted to various hospitals in Kelantan state over a six-year period. Fourteen age groups with a five-year rangeinterval were generated. There was a significant association between typhoid infection and sex of subjects, wherebyfemales were generally more susceptible than males. Ethnicity and district of typhoid patients did not show significantassociation.Conclusion, significance and impact of study: The observation of an increased number of typhoid cases with a malepredominance in the age group 5-14 and female predominance in the 20-60 age group calls for improved hygiene,continued public health education, together with better laboratory diagnostics to identify carriers, are some measures tocontrol this disease

Mapping pre and post earthquake land cover change in Melangkap, Kota Belud Sabah using multi-temporal satellite Landsat 8/OLI and Sentinel 2 Imagery

It is generally accepted that vegetation provides important ecosystem services especially in term of rainfall partitioning. This study aims to evaluate the influence of canopy structure namely crown area (CA), diameter at breast height (DBH), tree height (TH) and crown spread (CS) and stand density on the partitioning of rainfall. Twelve throughfall plots of 20 x 20 m with 64 gauges randomly placed within each plot were established. For stemflow measurements, all trees within a 100 m2 plot within the study area were collared. Interception loss was computed as the difference between precipitation and throughfall plus stemflow. Throughfall ranged from 73.47 – 82.32 % of the gross rainfall. Stemflow was found to be roughly around 2.01% of the gross rainfall. Highest interception was 24.52 % attributed to the plot having the highest above ground biomass (AGB) density. The relation between canopy interception and forest structure were analyzed by regression method. Multiple regression analysis on the potential influence of stand structure to the throughfall percentage shows that all the forest structures variables measured in this study are negatively correlated to the amount of throughfall generated. This study suggests that forests with higher value of DBH, CA, CS and TH had higher interception rate

Quantum Physics and Human Language

Human languages employ constructions that tacitly assume specific properties of the limited range of phenomena they evolved to describe. These assumed properties are true features of that limited context, but may not be general or precise properties of all the physical situations allowed by fundamental physics. In brief, human languages contain `excess baggage' that must be qualified, discarded, or otherwise reformed to give a clear account in the context of fundamental physics of even the everyday phenomena that the languages evolved to describe. The surest route to clarity is to express the constructions of human languages in the language of fundamental physical theory, not the other way around. These ideas are illustrated by an analysis of the verb `to happen' and the word `reality' in special relativity and the modern quantum mechanics of closed systems.Comment: Contribution to the festschrift for G.C.
