Female company directors are better judges of longer-term company performance

Groundbreaking research by the University of Exeter Business School reveals that female company directors defy negative gender stereotyping by astutely valuing future company performance.

The stock market responds more positively to trades made by male directors in their own company stock than their female counterparts, new research reveals.

However, over the longer term (3 – 12 months), returns made by female directors’ on trades in their own company stock are at least equal to, or exceed, those of their male counterparts.

The study by the University of Exeter Business School analysed over 80,000 legal trades made by directors of companies listed on the London and AIM stock exchanges. It is commonly assumed that when a director buys shares in their own company, they believe it to be undervalued by the stock market and this frequently leads to investors buying more stocks in that company and pushing up the share price.

Astronomers find evidence of hungry young exoplanets

While astronomers now know that exoplanets are exceedingly common in the galaxy, the mechanics by which they are formed aren’t well understood. Planetary childhood remains a mystery.

Young stars start out with a massive disk of gas and dust that over time, astronomers think, either diffuses away or coalesces into planets and asteroids.

“The speculation is that as planets form they clear out a region of gas and dust around them, forming a telltale ‘gap’ in the disk”, said Stefan Kraus, from Physics and Astronomy at the University of Exeter. (more…)

Bugs produce diesel on demand

It sounds like science fiction but a team from the University of Exeter, with support from Shell, has developed a method to make bacteria produce diesel on demand.

While the technology still faces many significant commercialisation challenges, the diesel, produced by special strains of E. coli bacteria, is almost identical to conventional diesel fuel.

This means that it does not need to be blended with petroleum products as is often required by biodiesels derived from plant oils. It also means that the diesel can be used with current supplies in existing infrastructure because engines, pipelines and tankers do not need to be modified. Biofuels with these characteristics are being termed ‘drop-ins’. (more…)

Perfectly mixed up

Drama has become a regular activity for Exeter’s young people in care who have joined forces with students from the University of Exeter to stage a play in Austin, Texas. Stetsons and cowboy boots are at the ready as Exeter’s creative gang of performers head to the United States.

This life changing experience will be the first time that the theatre company ‘Perfectly Mixed Up’ travel and perform outside of Devon. Throughout the week long stay the company will perform their show, More than the Sum, and run two workshops with young people in care in Austin, Texas. ‘Perfectly Mixed Up’ are guests of the University of Texas at Austin who have an exchange programme with the Drama department at University of Exeter.

Beetroot juice – the winning formula for team sports

New research shows that drinking beetroot juice can significantly improve performance in team sports involving bouts of high intensity exercise.

Trials by the University of Exeter Sport and Health Sciences department have found a direct link between the high nitrate content of beetroot and the chemical processes needed to get muscles working at their most efficient during intermittent bursts of activity.

During the tests, sportsmen were either given beetroot juice with a full complement of nitrates, or juice which had had the nitrate removed. Those who had taken the nitrate-rich juice were found to have a distinct advantage when exercising over those who had been given the control juice to drink. (more…)

Lungs of the Planet Reveal Their True Sensitivity to Global Warming

Tropical rainforests are often called the “lungs of the planet” because they generally draw in carbon dioxide and breathe out oxygen.

But the amount of carbon dioxide that rainforests absorb, or produce, varies hugely with year-to-year variations in the climate.

In a paper published online (Feb 6 2013) by the journal Nature, a team of climate scientists from the University of Exeter, the Met Office-Hadley Centre and the NERC Centre for Ecology & Hydrology, has shown that these variations reveal how vulnerable the rainforest is to climate change. (more…)

UK’s Most Confident and Successful Corporate Managers Live Abroad During Their Formative Years, New Research Reveals

Corporate managers widely exposed to more than one culture during their formative years (up until 23 years of age) are more likely to be confident taking difficult and risky decisions, such as acquisitions, new research from the University of Exeter Business School reveals.

The study looked at over 2,000 acquisition decisions taken by board members at 561 UK listed companies, and found that managers who live or study in cultures other than their own more readily take difficult strategic decisions such as deciding to acquire foreign companies.

Co-author, Grzegorz Trojanowski, Associate Professor in Finance at the University of Exeter Business School says corporate managers with wide exposure to different cultures tend to see doing business in foreign countries as providing great opportunities, and they expect to get a positive result from their business activities in these markets.

Bio-inspired Fibres Change Colour When Stretched

A team of materials scientists at Harvard University and the University of Exeter has invented a new fibre which changes colour when stretched. Inspired by nature, the researchers identified and replicated the unique structural elements, which create the bright iridescent blue colour of a tropical plant’s fruit.

The multilayered fibre, described in the journal Advanced Materials, could lend itself to the creation of smart fabrics that visibly react to heat or pressure.

“Our new fibre is based on a structure we found in nature, and through clever engineering we’ve taken its capabilities a step further,” says lead author Dr Mathias Kolle, a postdoctoral fellow at the Harvard School of Engineering and Applied Sciences (SEAS). “The plant, of course, cannot change colour. By combining its structure with an elastic material, however, we’ve created an artificial version that passes through a full rainbow of colours as it’s stretched.” (more…)
