ADHD-like behavior and entrepreneurial intentions

Little is known about the relation between validated psychiatric symptoms scores and the entrepreneurial decision. Building on the Person-Environment (P-E) fit literature and using data of over 10,000 students, we test whether individuals with higher levels of attention deficit and hyperactivity (ADHD) have higher entrepreneurial career intentions compared to others. We find that students reporting higher levels of ADHD-like behavior (assessed with a symptom score on an ADHD screening scale) are more likely than their peers to display entrepreneurial intentions and become student entrepreneurs. This can be partly explained by their high need for independence and their risk tolerance

ADHD-like behavior and entrepreneurial intentions

Little is known about the relation between entrepreneurship and the extent of psychiatric symptoms. Validated psychiatric symptom scores are seldom used for non-clinical reasons. One prevalent symptom that deserves our interest is Attention Deficit and Hyperactivity Disorder (ADHD). ADHD is a developmental disorder characterized by inattentiveness and hyperactivity that has been linked to occupational choice and performance. Building on the person–environment fit literature, we hypothesize that individuals who exhibit behavior associated with ADHD are more likely to have entrepreneurial intentions. Using a sample of 10,104 students enrolled in higher education, we can confirm our prediction that students with a higher level of ADHD-like behavior are more likely to have entrepreneurial intentions. Additionally, we show that risk taking propensity is a mediator that partly explains this positive effect. Our study points to the importance of behavioral tendencies associated with developmental disorders, when making entrepreneurship decisions. Our study contributes to the literature on the determinants of entrepreneurship, which so far has largely neglected the effects of psychiatric symptoms on entrepreneurship

Pion photoproduction on the nucleon in the quark model

We present a detailed quark-model study of pion photoproduction within the effective Lagrangian approach. Cross sections and single-polarization observables are investigated for the four charge channels, $\gamma p\to \pi^+ n$, $\gamma n\to \pi^- p$, $\gamma p\to \pi^0 p$, and $\gamma n\to \pi^0 n$. Leaving the $\pi N\Delta$ coupling strength to be a free parameter, we obtain a reasonably consistent description of these four channels from threshold to the first resonance region. Within this effective Lagrangian approach, strongly constrainted by the quark model, we consider the issue of double-counting which may occur if additional {\it t}-channel contributions are included.Comment: Revtex, 35 pages, 16 eps figures; version to appear on PR

Atlantic Bluefin Tuna Tagging Programme in Ireland 2017

It is important that stock origin, habitat utilisation and large-scale movement patterns of Atlantic bluefin are characterised in detail to ensure that the population models and concepts used in Atlantic bluefin tuna stock assessment and Management Strategy Evaluation (MSE) are parameterised as accurately as possible. Investigation of the distribution and movements of Atlantic bluefin tuna in Irish waters is now a priority for Ireland. The ocean waters off south Donegal are now regarded by the International Commission for the Conservation of Atlantic Tuna (ICCAT) as an important area for Atlantic bluefin tuna and indications are that significant numbers arrive in the area over the period August to November each year. The Department of Agriculture Food and the Marine (DAFM) requested that the Marine Institute carry out a bluefin tagging programme in autumn 2016 to support the International Commission for the Conservation of Atlantic Tuna (ICCAT) Grand Bluefin Year Programme (GBYP) Atlantic research programme for Bluefin tuna
