In two recent papers published in the Journal of Medicine & Science in Sports & Medicine, and in Scientific Reports, we showed that young athletes perform better in a sustained attention task compared to their sedentary counterparts. Interestingly, the benefits of exercise on attention are observed only during the first 30 minutes of the 1-hour task. After that, there are no differences in the performance of the two groups. We observe that during this enhanced attention period, athletes also exhibit significantly different EEG and heart period event-related potentials (ERPs). This novel finding points towards a previously unrecognised brain-heart interaction in the mediation of cognitive benefits induced by physical exercise. These interesting results on the role of regular exercise on attention have also attracted the attention of Spanish popular science journals.
A commentary I coauthored with Gary McDowell for the forthcoming ASAPbio conference on the future of preprints in Biology. It was originally published at the ASAPbio commentaries section: http://asapbio.org/open-scholar
In reforming the culture of peer review and moving towards a system that embraces the use and recognition of pre-print servers, we are cognizant of the need to avoid re-inventing the wheel, by identifying and using existing infrastructure and initiatives that can assist in furthering this goal.

In this recently published study we compared 30 experienced crisis managers with 30 managers from other disciplines, in terms of self-reported stress, health status and psychophysiological reactivity to crisis-related and non-specific visual and acoustic aversive stimuli and cognitive challenge. Crisis managers reported lower stress levels, a more positive strain-recuperation-balance, greater social resources, reduced physical symptoms, as well as more physical exercise and less alcohol consumption. They exhibited diminished electrodermal and heart rate responses to crisis-related and non-specific stressors.
The results indicate reduced stress and physical complaints, diminished psychophysiological stress reactivity, and a healthier life-style in crisis managers. Improved stress resistance may limit vulnerability to stress-related performance decline and facilitate preparedness for major incidents.

In our recently article published in “Frontiers in Behavioral Neuroscience“, we show that high emotional arousal is not solely associated to unethical economic behavior —such as tax evasion— as previous research had revealed. Instead, people get emotionally aroused also when making ethical choices if these choices imply the loss of monetary reward. In other words, it seems to be more stressful for someone to lose money than to make an unethical decision that causes a loss of money to others. This means that, in certain circumstances, our bodies reward unethical decisions in order to minimise the unpleasant feeling produced by decisions that cost us money. This behavior is inverted when the possibility of punishment exists. In that case corrupt decisions become more stressful than ethical ones.
These results support the existence of severe external control in economic transactions and bare important consequences for the political fight against corruption.

We recently published a research article where we examined the effects of viewing a video of one’s own body on the physiological (eye-blink startle, cardiac defense, and skin conductance) and subjective (pleasure, arousal, and control ratings) responses elicited by a burst of 110 dB white noise of 500 ms duration. The results showed that, when viewing their own bodies, women with BN experienced (a) greater inhibition of the startle reflex, (b) greater cardiac acceleration in the first component of the defense reaction, (c) greater skin conductance response, and (d) less subjective pleasure and control combined with greater arousal, compared with the control participants. The findings suggest that, for women with BN, peripheral-physiological responses to self-images are dominated by attentional processes, which provoke an immobility reaction caused by a dysfunctional negative response to their own body.
The feature article on last Sunday’s Vima Science discussing University Rankings presented a research paper authored by Michael Taylor, Varvara Trachana, Stelios Gialis and myself. The Vima Science article uses data and arguments presented in our paper to criticise current University indices that are constructed from a list of arbitrary indicators combined using subjective weightings. The article specifically focuses on how these rankings fail to capture the high productivity of Greek scientists and University students as measured through citation data, and discusses Michael’s suggestions on what criteria should students and parents use in order to select a suitable University.

After a long delay, our debate article “Academic self-publishing: a not-so-distant future” finally appeared at Prometheus, a journal publishing critical studies in innovation. The journal issue hosting our article was originally expected in September 2013, but a series of unfortunate events resulted in an eight-month standoff between the journal’s editorial team and its publisher Taylor & Francis. In short, the debate proposition paper, authored by four academics from the University of Leicester’s School of Management, harshly criticized the large profits made by major publishing firms on the back of academics’ labors and the failure of the Finch report on open access to address this problem.
