Effects of visual and motion simulation cueing systems on pilot performance during takeoffs with engine failures

Data are presented that show the effects of visual and motion during cueing on pilot performance during takeoffs with engine failures. Four groups of USAF pilots flew a simulated KC-135 using four different cueing systems. The most basic of these systems was of the instrument-only type. Visual scene simulation and/or motion simulation was added to produce the other systems. Learning curves, mean performance, and subjective data are examined. The results show that the addition of visual cueing results in significant improvement in pilot performance, but the combined use of visual and motion cueing results in far better performance

Application of the ex-Gaussian function to the effect of the word blindness suggestion on Stroop task performance suggests no word blindness

The aim of the present paper was to apply the ex-Gaussian function to data reported by Parris et al. (2012) given its utility in studies involving the Stroop task. Parris et al. showed an effect of the word blindness suggestion when Response-Stimulus Interval (RSI) was 500 ms but not when it was 3500 ms. Analysis revealed that: (1) The effect of the suggestion on interference is observed in μ, supporting converging evidence indicating the suggestion operates over response competition mechanisms; and, (2) Contrary to Parris et al. an effect of the suggestion was observed in μ when RSI was 3500 ms. The reanalysis of the data from Parris et al. (2012) supports the utility of ex-Gaussian analysis in revealing effects that might otherwise be thought of as absent. We suggest that word reading itself is not suppressed by the suggestion but instead that response conflict is dealt with more effectively. © 2013 Parris, Dienes and Hodgson

The Patterns of Venture Capital Investment in the UK Bio-Healthcare Sector:The Role of Proximity, Cumulative Learning and Specialisation

This paper focuses on the patterns of venture capital (VC) investment in dedicated biotech firms (DBFs) in the therapeutic and diagnostic sectors (bio-healthcare). We use a database of 655 UK bio-healthcare deals to map the geographical flows of VC investment and measure the co-location of investors and DBFs. Then, using 20 face-to-face interviews with venture capitalists (VCs) and DBF firms in Cambridge and Scotland, we study the strategic motives underlying the co-location of investors and investee companies and reflect on the catalytic role VCs play in context of the Scottish and Cambridge bio-clusters. From the viewpoint of VC-related policies, we find that our study is more in line with arguments stressing the attractive power of ‘investor-ready’ opportunities (Mason and Harrison 200327. Mason , C. M. and Harrison , R. T. 2003 . Closing the regional equity gap? A critique of the Department of Trade and Industry's Regional Venture Capital Funds Initiative . Regional Studies , 37 ( 8 ) : 855 – 868 . [Taylor &amp; Francis Online], [Web of Science ®]View all references) than supply-side approaches that take for granted VC presence at the core of high-tech clusters. In line with Avnimelech, Rosiello, and Teubal (20082. Avnimelech , G. , Rosiello , A. and Teubal , M. 2008 . A discussion on the theoretical foundations of VC policy: Moving from a financial perspective towards a systemic and evolutionary framework ESRC Innogen Centre Working Paper. www.innogen.ac.uk (accessed December, 2008) View all references), we propose that VC policy should be consistent with the wider strategic objectives of innovation and technology policy.<br/

Traversal Times for Random Walks on Small-World Networks

We study the mean traversal time for a class of random walks on Newman-Watts small-world networks, in which steps around the edge of the network occur with a transition rate F that is different from the rate f for steps across small-world connections. When f >> F, the mean time to traverse the network exhibits a transition associated with percolation of the random graph (i.e., small-world) part of the network, and a collapse of the data onto a universal curve. This transition was not observed in earlier studies in which equal transition rates were assumed for all allowed steps. We develop a simple self-consistent effective medium theory and show that it gives a quantitatively correct description of the traversal time in all parameter regimes except the immediate neighborhood of the transition, as is characteristic of most effective medium theories.Comment: 9 pages, 5 figure

Facilitating goal-oriented behaviour in the Stroop task: when executive control is influenced by automatic processing.

A portion of Stroop interference is thought to arise from a failure to maintain goal-oriented behaviour (or goal neglect). The aim of the present study was to investigate whether goal- relevant primes could enhance goal maintenance and reduce the Stroop interference effect. Here it is shown that primes related to the goal of responding quickly in the Stroop task (e.g. fast, quick, hurry) substantially reduced Stroop interference by reducing reaction times to incongruent trials but increasing reaction times to congruent and neutral trials. No effects of the primes were observed on errors. The effects on incongruent, congruent and neutral trials are explained in terms of the influence of the primes on goal maintenance. The results show that goal priming can facilitate goal-oriented behaviour and indicate that automatic processing can modulate executive control

Adiabatic-Nonadiabatic Transition in the Diffusive Hamiltonian Dynamics of a Classical Holstein Polaron

We study the Hamiltonian dynamics of a free particle injected onto a chain containing a periodic array of harmonic oscillators in thermal equilibrium. The particle interacts locally with each oscillator, with an interaction that is linear in the oscillator coordinate and independent of the particle's position when it is within a finite interaction range. At long times the particle exhibits diffusive motion, with an ensemble averaged mean-squared displacement that is linear in time. The diffusion constant at high temperatures follows a power law D ~ T^{5/2} for all parameter values studied. At low temperatures particle motion changes to a hopping process in which the particle is bound for considerable periods of time to a single oscillator before it is able to escape and explore the rest of the chain. A different power law, D ~ T^{3/4}, emerges in this limit. A thermal distribution of particles exhibits thermally activated diffusion at low temperatures as a result of classically self-trapped polaronic states.Comment: 15 pages, 4 figures Submitted to Physical Review

Working in teams : the influence of rhetoric-from sensemaking to sadness

At a time when teams are increasingly and routinely being used in Public Administration (PA) organizations, the prevailing wisdom about teams continues to confirm that teams axiomatically bring increases and improvements in effectiveness, productivity and communication. There has been relatively little critical address of whether these benefits actually accrue, nor what the experience of team members actually is. The PA literature, in particular, remains silent on this important issue. This paper shares findings from an exploratory phenomenological study. Members of teams in organizations were interviewed and asked about their experiences of working in teams. In contrast to the current wisdom, not only did team members not report the anticipated improvements and benefits, their stories tended to highlight the negative influence that the rhetoric surrounding teams might have on individuals. This paper shares the responses of team members to that rhetoric, revealing themes of &quot;Teams, Rhetoric and Sensemaking,&quot; a challenge to the notion of &quot;Teams as One Big Happy Family?&quot; while identifying &quot;Teams as Crucibles of Resignation and Sadness.&quot; These findings indicate the continuing need for further research into understanding the experience of individuals within various team and organizational structures, especially as they operate in PA organizations.<br /
