Vibration was applied to the tendon of flexor carpi radialis while recording the EMG of the wrist flexors in 29 Parkinsonian patients. Cessation of the vibration led to a small short-latency (approximately 25 ms) reduction in the level of activity which did not differ in magnitude from the normal. Moreover, there was no sign of any subsequent long-latency reduction of activity. Thus the maintai...

The agency theory upholds shareholder value orientation and suggests the consolidation of monitoring mechanisms in order to correct inappropriate behaviors of managers and consequently, to improve corporate performance (Cuervo-Cazurra & Dau, 2009; Schulze, Lubatkin, Dino, & Buchholtz, 2001; Sundaram & Inkpen, 2004). Contrary to the theoretical prescription, however, shareholder-oriented mechani...

Invasive alien species cause significant impacts in agriculture, forestry and the environment, with worldwide economic losses estimated at US $ 1.4 trillion annually, or roughly 5% of the current global economy (Pimentel et al., 2001) and likely to increase in the near future (Perrings et al., 2005; Westphal et al., 2008). In recent decades, quantitative models have become increasingly popular ...

In this note we theoretically investigate the question of whether the relationship between public debt and economic growth is characterized by an inverse U-shaped functional form. Starting point of our analysis is the paper by Checherita-Westphal et al. (2012) who present an endogenous growth model with public capital and public debt that displays a hump-shaped relation between debt and economi...

Changes in accommodative dynamics with repeated accommodation were studied in three anesthetized rhesus monkeys and two conscious humans. Maximum accommodation was centrally stimulated via the Edinger-Westphal nucleus in monkeys with a 4 s on, 4 s off paradigm (4 x 4) for 17 min, 4 x 1.5 for 27 min and 2 x 1 for 16 min. Humans accommodated repeatedly to visual targets (5 x 5; 5D and 2 x 2; 6D) ...

A-closure is the equivalent of path consistency for qualitative spatiotemporal calculi with weak composition. We revisit existing attempts to characterize the question whether a-closure is a complete method for deciding consistency of CSPs over such calculi. Renz and Ligozat’s characterization via closure under constraints has been refuted by Westphal, Hué and Wölfl. However, for many commonly ...

A 13-year-old boy presented with emesis, blurred vision, headache, and vertigo. He showed signs of a dorsal midbrain (Parinaud) syndrome (supranuclear upgaze palsy, convergence retraction nystagmus, Collier sign [lid retraction], pupillary light-near-dissociation)1 and eccentric displacement of the pupils (corectopia; figure 1 and figure e-1 on the Neurology Web site at www.neurology.org).
