Purpose This paper aims to quantify the impact of craft worker shortage on construction project safety performance. Design/methodology/approach A database of 50 North American construction projects completed between 2001 and 2014 was compiled by taking information from a research project survey and the Construction Industry Institute Benchmarking and Metrics Database. The t-test and Mann-Whitney test were used to determine whether there was a significant difference in construction project safety performance on projects with craft worker recruiting difficulty. Poisson regression analysis was then used to examine the relationship between craft worker recruiting difficulty and Occupational Safety and Health Administration Total Number of Recordable Incident Cases per 200,000 Actual Direct Work Hours (TRIR) on construction projects. Findings The result showed that the TRIR distribution of a group of projects that reported craft worker recruiting difficulty tended to be higher than the TRIR distribution of a group of projects with no craft worker recruiting difficulty (p-value = 0.004). Moreover, the average TRIR of the projects that reported craft worker recruiting difficulty was more than two times the average TRIR of projects that experienced no craft recruiting difficulty (p-value = 0.035). Furthermore, the Poisson regression analysis demonstrated that there was a positive exponential relationship between craft worker recruiting difficulty and TRIR in construction projects (p-value = 0.004). Research limitations/implications The projects used to construct the database are heavily weighted towards industrial construction. Practical implications There have been significant long-term gains in construction safety within the USA. However, if recent craft shortages continue, the quantitative analyses presented herein indicate a strong possibility that more safety incidents will occur unless the shortages are reversed. Innovative construction means and methods should be developed and adopted to work in a safe manner with a less qualified workforce. Originality/value The Poisson regression model is the first model that quantifiably links project craft worker availability to construction project safety performance.

Modern Medical Practice

Laparoscopic robots have been widely adopted in modern medical practice. However, explicitly interacting with these robots may increase the physical and cognitive load on the surgeon. An attention-aware robotic laparoscope system has been developed to free the surgeon from the technical limitations of visualization through the laparoscope. This system can implicitly recognize the surgeon's visual attention by interpreting the surgeon's natural eye movements using fuzzy logic and then automatically steer the laparoscope to focus on that viewing target. Experimental results show that this system can make the surgeon–robot interaction more effective, intuitive, and has the potential to make the execution of the surgery smoother and faster.

Effective Use

The main goal of this research is to investigate how learners with different cultural background differ in their interaction style and visual behavior in multimedia-enhanced education, more specifically between groups from the African vs. Asian regions. The researchers conducted a controlled eye-tracking experiment to explore and evaluate the visual behavior of African, Afghan, Japanese and Chinese learners when scanning through different online multimedia contents. The analysis of their eye-gaze patterns and heat-maps revealed significant differences in terms of learners' interaction style, gender, color, text or multimedia preferences. This cross-cultural investigation collectively contributes towards effective use of multimedia technologies in education that ultimately increases learners' engagement and retention.

Japanese Garden

Aim: To explore people’s visual attention and psychological and physiological responses to viewing a Japanese garden (an asymmetrically designed garden) and an herb garden (a symmetrically designed garden). Background: There are few studies of eye movements when observing different style gardens, and how they are connected to the interpretation of the space, and physiological and psychological responses. Method: Thirty subjects were recruited and their physiological and psychological responses to viewing the garden types were assessed using a heart-rate monitor and questionnaire. Eye movements while viewing projected slide images of the gardens were tracking using an eye-tracking monitor. Results: A significant decrease in heart rate was observed when subjects were viewing the Japanese garden as opposed to viewing the herb garden. Mood was significantly improved in both gardens, but eye-gaze patterns differed. The Japanese garden elicited far more comments about expectations for the coming season; unlike the herb garden, it also induced memories of viewing other landscapes. Conclusion: The physiological and psychological responses to viewing gardens differs based on the quality of landscape design and the prior experience of viewers.
