Investigating Gender Differences under Time Pressure in Financial Risk Taking.

There is a significant gender imbalance on financial trading floors. This motivated us to investigate gender differences in financial risk taking under pressure. We used a well-established approach from behavior economics to analyze a series of risky monetary choices by male and female participants with and without time pressure.

Interoceptive Ability Predicts Survival on a London Trading Floor.

Interoception is the sensing of physiological signals originating inside the body, such as hunger, pain and heart rate. People with greater sensitivity to interoceptive signals, as measured by, for example, tests of heart beat detection, perform better in laboratory studies of risky decision-making. However, there has been little field work to determine if interoceptive sensitivity contributes to success in real-world, high-stakes risk taking.

Cortisol shifts financial risk preferences.

Risk taking is central to human activity. Consequently, it lies at the focal point of behavioral sciences such as neuroscience, economics, and finance. Many influential models from these sciences assume that financial risk preferences form a stable trait.

Changes in hip fracture incidence, mortality and length of stay over the last decade in an Australian major trauma centre.

Purpose: The aim of this study was to describe the population-based longitudinal trends in incidence, 30-day mortality and length of stay of hip fracture patients in a tertiary referral trauma centre in Newcastle, New South Wales, Australia, and identify the factors associated with increased 30-day mortality.

Methods: A retrospective database and chart review was conducted to patients aged ≥65 years with a diagnosis of femoral neck or pertrochanteric fracture admitted to the John Hunter Hospital between 01 January 2002 and 30 December 2011. The main outcome measure was 30-day mortality; secondary outcome was acute length of stay.

Repair of traumatic muscle herniation with acellular porcine collagen matrix.

Background: Muscle hernias are uncommon clinical conditions with no uniform solution of repair. Biocompatible mesh allows for repair of hernias without the donor site morbidity and complications from direct repair under tension.

Methods: Over a 6-month period at a Level 1 Trauma centre, four consecutive symptomatic muscle hernias were identified, two in the forearm and two in the lower limb.
