Self-regulation of older drivers with cognitive impairment : a systematic review

Background
Cognitive decline contributes significantly to the safety risk of older drivers. Some drivers may be able to compensate for the increased crash risk by avoiding complex driving situations or restricting their driving.

Objective and Method
A comprehensive English-language systematic review was conducted to determine the level of evidence for older adult drivers with cognitive impairment engaging in self-regulation.

Results
Twelve studies were included in the review. The majority of studies investigated driver avoidance, followed by driver restriction. Few studies ascertained the reasons for changing driving behaviour.

Conclusions
The evidence supports the view that drivers with cognitive impairment do restrict their driving and avoid complex driving situations. However, it remains to be determined whether the drivers who do engage in self-regulation require insight into their own driving abilities or whether external factors result in self-regulation of driving behaviour.

Business group affiliation, board quality and audit pricing behavior: evidence from indian companies

This study examines the relationships among business group affiliation, board quality and audit fees in an emerging market setting. Using data from Indian firms listed on the Bombay Stock Exchange (BSE) over a nine-year period (2004-2012), our results indicate that firms affiliated with a business group pay higher audit fees than those without such affiliations. We also find that group-affiliated firms with higher-quality boards pay relatively higher audit fees compared to other counterparts. Further, our findings suggest that group-affiliated firms pay lower fee premiums when an audit is undertaken by a Big 4 firm or its affiliates, which implies that economies of scale may be a potential competitive advantage held by larger auditors. The results of the study have implications for the management of audit fees by group-affiliated firms through board structure and processes.
