Is active travel a breath of fresh air? Examining children's exposure to air pollution during the school commute.

The aim of this study was to assess how children's personal exposure to fine particulate matter (PM) during the school commute is influenced by mode of travel and neighborhood environment in a mid-sized Canadian city. A total of 101 commutes to and from school were tracked using a GPS, and personal exposure to PM along commute routes was assessed by spatially-referencing the monitored exposure levels with time-synchronized GPS data. Students who walked to and from school were exposed to lower PM concentrations than those in cars or riding the school bus.

A "Collective Effort to Make Yourself Feel Better": The Group Process in Mindfulness-Based Interventions.

There is growing interest in mindfulness-based interventions (MBIs) in the management of multiple physical and mental health issues. Although MBIs utilize a group format, research on how this format impacts teaching and learning mindfulness is lacking. This study aimed to develop a detailed theory of MBI group processes utilizing a grounded theory methodology.

In Silico Identification of Bioremediation Potential: Carbamazepine and Other Recalcitrant Personal Care Products.

Emerging contaminants are principally personal care products not readily removed by conventional wastewater treatment and, with an increasing reliance on water recycling, become disseminated in drinking water supplies. Carbamazepine, a widely used neuroactive pharmaceutical, increasingly escapes wastewater treatment and is found in potable water. In this study, a mechanism is proposed by which carbamazepine resists biodegradation, and a previously unknown microbial biodegradation was predicted computationally.

Images of otoscopy: rate and extent of non-compliance with good practice standards.

Background: The British Society of Audiology has produced clear guidelines as to how otoscopy should be undertaken; however, no nationally recognised guidelines exist for the wider clinical community. Images of otoscopy appear in many books, journals, magazines and websites.

Objective: This study aimed to determine the rate of non-compliance with good practice in images of otoscopy, the seriousness of the breach, and whether this is more common in sites for professionals or the general public.
