Development and Evaluation of an Online Acceptance and Commitment Therapy Program for Anxiety: Phase I Iterative Design

This exploratory, nonclinical study evaluated the user experience of an online acceptance and commitment therapy program for anxiety. Forty young Australian adults aged between 18 to 25 years old completed the online program over 2 weeks. System usability and perceived helpfulness were evaluated at posttest. Self-rated levels of anxiety, depression, stress, and psychological flexibility were measured at pretest, posttest, and 2-week follow up. System usability was rated above average and significant improvements were found on all mental health measures from pretest to follow-up, except for stress. These results warrant further scrutiny in a clinical randomized controlled trial on the intervention.     

Building information modelling in construction: insights from collaboration and change management perspectives

A case study is used to obtain the experiences from a contractor and their subcontractors involved with constructing the landmark Perth Stadium, which required a building information model (BIM) to be delivered for the purpose of asset management. Insights about ‘how’ the adoption of a BIM influenced the practice of collaboration and change management within the project are obtained. It was revealed that having limited experience and knowledge to deliver a model for asset management often resulted the project team ‘muddling through a problem’. This was not necessarily due to a shortage of training, but a lack of BIM knowledge, which inadvertently influenced every day practice. The research presented builds on the extant body of works that have examined how the construction industry can effectively acquire the benefits of BIM for asset management. It also highlights the need to incorporate education and learning into a project’s BIM implementation strategy.     

The Time-Course for the Capture and Hold of Visuospatial Attention by Fearful and Happy Faces

Fearful faces both capture our attention and hold it. However, little is known about the time-course for the capture and hold of spatial attention by fearful, and other emotional, faces. In three dot-probe studies we examined this time-course. Experiments 1 and 2 used fearful and neutral faces. In Experiment 1, dot-probe targets occurred 133, 266, and 532 ms post-face onset and in Experiment 2, dot-probe targets occurred 84, 168, 336, and 672 ms post-face onset. In Experiment 1, for both 133 and 266 ms conditions, reaction times were fastest for congruent trials and slowest for incongruent trials with reaction times for baseline trials falling between the two. The same pattern was found for the 84 and 168 ms conditions in Experiment 2. For the later time-points in both experiments there were no significant differences between conditions. To examine whether this time-course is unique to fearful faces, a third dot-probe experiment using time-points identical to Experiment 2 was conducted with happy and neutral faces. The results from Experiment 3 suggest that happy faces captured and held attention in the 168 and 336 ms conditions. Together, the results indicate that attention is captured and held by fearful faces at times earlier than approximately 300 ms, while happy faces also captured and held attention, but on a slightly different time-course from 168 to 336 ms.     

Formal Alternative Transportation Options for Older Adults: An Assessment of Need

ABSTRACT

This study measured the need for formal alternative modes of transportation among older adults by applying traditional factors of the Behavioral Model. Survey participants who regularly drove were compared to those who could no longer drive. Race/ethnicity and self-reported health were significant predictors of perceived need for transportation services for both groups. However, income and service awareness were significant predictors only for drivers, while family proximity was a significant predictor only for non-drivers. Results suggest the importance of gaining a better understanding of the factors associated with need for senior-focused transportation services to more effectively plan such programs.     

Minimum Wages in a Segmented Labor Market: Evidence from South Africa

The segmented labor market model describes the impacts of minimum wages on covered and uncovered sectors. This paper examines the impacts of an industry-specific minimum wage in South Africa, a state characterized by high unemployment, a robust union movement, and the presence of a large informal sector. Under the industry-specific wage law, formal agricultural and household workers are covered, while workers in other sectors are not. The unique aspect of this paper lies in the ability to compare the impacts of minimum wage legislation on formal covered, informal covered, formal uncovered, and informal uncovered workers. This natural experiment allows us to test whether industry-specific minimum wage legislation leads to higher wages, whether wage increases are restricted solely to covered formal sectors or if there are spillover effects, and whether such legislation manifests in disemployment effects. We find evidence of higher wages yet disemployment among black workers in formal markets. In informal markets we find no employment effects, but higher wages in formal markets appear to have spilled over into informal markets in covered sectors.     

EXPONENTIAL‐GROWTH BIAS AND LIFECYCLE CONSUMPTION

Exponential‐growth bias (EGB) is the tendency for individuals to partially neglect compounding of exponential growth. We develop a model wherein biased agents misperceive the intertemporal budget constraint, and derive conditions for overconsumption and dynamic inconsistency. We construct an incentivized measure of EGB in a US‐representative population and find substantial bias, with approximately one third of subjects estimated as the fully biased type. The magnitude of the bias is negatively associated with asset accumulation, and does not respond to a simple graphical intervention.     

Longer Life and Population Growth

Enthusiasm about the prospect of large increases in human life expectancy is often dampened by fears that lower mortality will increase population size, hence population pressure. A simple mathematical model of life-cycle stretching demonstrates that if increased longevity is accompanied by later childbearing, a trend that is already underway, future declines in mortality will not increase population size.     

Global patterns of healthy life expectancy for older women

This paper focuses on patterns of healthy life expectancy for older women around the globe in the year 2000, and on the determinants of differences in disease and injury for older ages. Our study uses data from the World Health Organization for women and men in 191 countries. These data include a summary measure of population health, healthy life expectancy (HALE), which measures the number of years of life expected to be lived in good health, and a complementary measure of the loss of health (disability-adjusted life years or DALYs) due to a comprehensive set of disease and injury causes. We examine two topics in detail: (1) cross-national patterns of female-male differences in healthy life expectancy at age 60; and (2) identification of the major injury and disability causes of disability in women at older ages. Globally, the male-female gap is lower for HALE than for total life expectancy. The sex gap is highest for Russia (10.0 years) and lowest in North Africa and the Middle East, where males and females have similar levels of healthy life expectancy, and in some cases, females have lower levels of healthy life expectancy. We discuss the implications of the findings for international health policy.
