Economic implications of access to daylight and views in office buildings from improved productivity

Previous research has found significant impacts of daylight and views on the cognitive function of office workers. In this study, we use scores on decision-making performance to estimate the annual economic potential of optimizing daylighting and views in U.S. offices. Cognitive scores were compared against over 100,000 previous test scores to obtain the distributional shift in cognitive performance when working in an office with optimized daylighting and views as opposed to an office with traditional blinds. These changes in performance were then compared to compensation data from the Bureau of Labor Statistics. Office workers shifted on average from the 52nd percentile to 65th percentile, equivalent to a $11,809 difference in salary per person per year. When conservatively accounting for the number of employees working within 15 ft of a window with blinds, optimizing daylight and views in U.S. offices has the potential to generate $352B ($240B–$464B), or 1.7% of the 2018 U.S. gross domestic product (GDP), in additional productivity. These findings suggest that building developers, architects and tenants should give additional attention to daylight design and façade technology as they consider new building construction, renovation and leasing options.     

Effects of Alprazolam on Complex Human Functioning1

Benzodiazepines can reduce anxiety, can have favorable effects upon sleep, and may diminish problems that interfere with patients' quality of life. On the other hand, these drugs can generate transient anterograde amnesia and may diminish aspects of task performance. Research on the impact of alprazolam and other “tranquilizing” drugs has generally focused on tasks that remain below the complex efforts of managerial or professional personnel. Alprazolam-induced reduction of anxiety under challenging conditions might aid complex task performance, yet anterograde amnesia might interfere. In the present research, managers participated in validated complex simulation tasks. In a double-blind, dual crossover design, placebo, 0.5 mg, or 1.0 mg alprazolam was administered on 2 occasions during the task day. Drug treatment diminished performance on measures that require sequential actions but improved performance on measures less subject to short term memory but more determined by long-term style of functioning. Thus, depending on task requirements, positive or negative alteration of performance might occur.     

Effectiveness of cognitive-behavioral therapy for adolescent depression: a benchmarking investigation

In this study, we examined the effectiveness of cognitive-behavioral therapy (CBT) for adolescent depression. Outcomes of 80 youth treated with CBT in an outpatient depression specialty clinic, the Services for Teens at Risk Center (STAR), were compared to a "gold standard" CBT research benchmark. On average, youths treated with CBT in STAR experienced significantly slower symptom improvement than youths in the CBT benchmark. However, outcomes for STAR teens were more similar to the research benchmark when accounting for differences in referral source (clinical versus advertisement) between the datasets. Results support further efforts to test the effectiveness of CBT in clinically representative community practice settings and samples.     

When Does Yoga Work? Long Term and Short Term Effects of Yoga Intervention among Pre-adolescent Children

In this research, pre-adolescent children of two city schools were randomly assigned to three conditions of a systematic yoga intervention, a non-yogic intervention and a time lagged comparison group intervention. Three assessments at baseline, three months and six months were done on a sample of 178 school children of class fifth and sixth. The outcome variables were anthropometric, cognitive, personality variables and self reported class room behaviours. Various directional hypotheses based on review of literature were tested. In particular, to understand the short term and long term effects of yoga intervention on children, repeated measures analysis and discriminant function analysis was used, which is discussed in the present paper. Results reveal that the effect of yoga interventions emerge only at long term, where the yoga group is clearly ahead of the non-yogic and time -lagged group on a cluster of factors termed as “positive health”. Implications are discussed.
