Anaesthesia associated developmental neurotoxicity (AADN) 2015

The long-term cerebral effects of general anaesthesia at the extremes of age are currently enjoying attention. In children, the concern is that exposure to anaesthesia when less than 4 years of age may cause subsequent learning disabilities and behavioural changes. However, clinical equipoise exists as the available human studies are imperfect and the results of the large-scale multinational trials are not yet available. This structured narrative review summarises the overwhelming amount of information available.‘Everything should be as simple as it can be, but not simpler.’(Albert Einstein

Regulation and the trickle-down effect of women in leadership roles

We use an event study design to provide evidence demonstrating how the trickle-down effect is influenced by the introduction of regulation on board gender diversity. In 2011, a new regulation was suddenly introduced for firms listed on the United Kingdom’s FTSE 350 index, the regulatory intervention put forward recommendations to increase the representation of women on the boards of FTSE 350 listed firms – the most critical recommendation was a voluntary target of having twenty-five percent of board positions held by women. We argue this change in regulation represents an exogenous shock, we utilize this shock to investigate how regulation influences the trickle-down of women’s representation from board level to senior management. We find evidence of a positive relationship between women on boards and women’s representation in senior management during the pre-regulation era – otherwise referred to as the trickle-down effect. However, the introduction of regulation had the unintended consequence of weakening the relationship between women on boards and women in senior management. Our results suggest that the trickle-down effect varies between different contexts and settings. We discuss the implications for research and practice

Improved Method for Quantifying the Air-Sea Flux of Volatile and Semi-Volatile Organic Carbon

A method for quantifying the diffusive air-sea exchange of gaseous organic carbon (OC) was developed. OC compounds were separated into two operational pools-those that were kinetically air limited in diffusion across the air-sea interface and those that were water limited-during simultaneous air/water sampling. The method separates OC compounds into low Henry\u27s law constant (low-H) semivolatile OC (SOC) and high Henry\u27s law constant (high-H) volatile OC (VOC) pools that can be categorized by relating diffusion kinetic parameters to Henry\u27s Law constant. Air limited (low-H; H \u3c\u3c similar to 0.1 L atm mol(-1)) compounds were collected in pure water traps and were quantified as dissolved OC, whereas water limited (high-H; H \u3e\u3e similar to 0.1 L atm mol-1) compounds were collected on solid sorbent tubes downstream from the water traps and were analyzed by gas chromatography-flame ionization detection (GC-FID). Separating OC based on H, rather than measuring OC as one bulk pool, allows improved estimates of OC concentration gradients and fluxes. A 10-month field study in the York River Estuary in Gloucester Point, VA revealed an average VOC flux of 138 µg C m-2 d-1 and an average SOC flux of 832 µg C m-2 d-1 (positive fluxes denote sea to air transfer)
