Work-related stress in construction management can trigger impairment to employees' psychological health, and thus affect project performance, but psychological disorders' deleterious consequences on project performance have not received sufficient attention in the literature. This study aims to identify different types of psychological disorders in construction projects and to develop a fuzzy mapping to determine the impact of psychological disorders in the context of time, cost, and quality in construction management. Through a questionnaire survey assisted by pair-wise comparison among experienced construction personnel, the six most common psychological disorders, including depression, generalized anxiety disorders (GAD), obsessive-compulsive disorders (OCD), substance use disorders (SUD), acrophobia, and claustrophobia, were analyzed using principal component analysis (PCA), partial least-square (PLS) tests, and fuzzy analytic hierarchy process (fuzzy-AHP), and followed by visualization. Although various stressors such as work overload, role ambiguity and conflict, unpaid overtime, restrictive career progression, and the diverse range of personalities are common in construction management, different roles and positions are subjected to different levels of stress, which from high to low are project manager, civil engineer, architect, contractor, quantity surveyor, and mechanical and electrical (M&E) engineer. This research developed fuzzy mapping of psychological disorders in the context of project performance, which is useful for project management teams to reveal and tackle mental health problems in early stages. © 2016 American Society of Civil Engineers.

The PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.
