The performance concept in the construction field is very broad, can occur within the project scope and building, suggesting effective ways to evaluate according to the activities involved. Although a large number of studies on construction project performance (CPP) and performance-based building (PBB) have been conducted in the last decade, there remains a lack of consensus among researchers and professionals regarding how to integrate PBB-related activities into the construction project phases (design, planning, construction and operation). After an in-depth analysis of hundreds of journal articles published between 2008 and 2018, this study provides a holistic understanding and critical reflection on the nexus between CPP and PBB, systematically illustrated by a “Performance information mapping” and a “Performance Taxonomy Framework” at each project phase in the strategic decision-making process. The results can help future researchers and professionals to conduct searches that are more relevant and to design, aiming at steps to ensure project success and building efficiency. A systematic review contributes to a better understanding of the performance concept in the construction field because it covers an unprecedented performance study of both stages, process management and product performance requirements in the construction industry. The review concludes by suggesting, as further work, a search for an integration tool.

<p><em>AdaBoost along with HaarCascades have been well received for its accuracy and performance in primarily Facial Recognition applications. However, they are known to perform poorly with objects which have a different rotational orientation or for objects whose shapes are largely variant . In this paper, we apply Adaptive Cascading technique to a specific dermatological application of detecting red acne which are largely shaped variant outgrowths on the skin and to identify its suitability in the detection of acne. Based on the outcome it would be declared if Viola-Jones based Adaptive Boosting is well suited for dermatological processing of skin diseases.</em></p>

A recent series of experiments suggests that fostering superstitions can substantially improve performance on a variety of motor and cognitive tasks ( Damisch, Stoberock, & Mussweiler, 2010 ). We conducted two high-powered and precise replications of one of these experiments, examining if telling participants they had a lucky golf ball could improve their performance on a 10-shot golf task relative to controls. We found that the effect of superstition on performance is elusive: Participants told they had a lucky ball performed almost identically to controls. Our failure to replicate the target study was not due to lack of impact, lack of statistical power, differences in task difficulty, nor differences in participant belief in luck. A meta-analysis indicates significant heterogeneity in the effect of superstition on performance. This could be due to an unknown moderator, but no effect was observed among the studies with the strongest research designs (e.g., high power, a priori sampling plan).
