There has been a lively debate about the potential impact of global climate change on U.S. agriculture. Most of the early agro-economic studies predict large damages (see, (1994)-hereafter MNS-propose a new approach: using the variation in temperature and precipitation across U.S. counties to estimate a reduced form hedonic equation with the value of(More)
PURPOSE The aetiology of tennis elbow has remained uncertain for more than a century. To examine muscle imbalance as a possible pathophysiological factor requires a reliable method of assessment. This paper describes the development of such a method and its performance in healthy subjects. We propose a combination of surface and fine-wire EMG of shoulder(More)
The research questions and topics most likely to emerge in the near term future are assessed. A common theme is that policy issues will be an important driving force, as has generally been true in the past. More specifically, future theoretical advances are expected to occur in the treatment of uncertainty, the incorporation of stock service flows into(More)
Among others who point to environmental variability and managerial uncertainty as causes of fishery collapse, Roughgarden and Smith (Proc. Natl. Acad. Sci. 93 (1996) 5078) argue that three sources of uncertainty are important for fisheries management: variability in fish dynamics, inaccurate stock size estimates, and inaccurate implementation of harvest(More)
Despite the existence of a large and growing literature on the potential impact of climate change on agriculture, there still exists some disagreement about the magnitude and even the sign. Our own research suggests that the impact on U.S. agriculture is likely to be strongly negative, based on a series of studies in which we link farmland values to climate(More)
A 35 month old child was referred for electrophysiology testing with pendular nystagmus, corresponding head oscillations and reduced vision. Flash visual evoked potential (VEP) revealed large responses at the right occiput (but not the left occiput) from the right eye and similar large responses at only the left occiput from the left eye, indicating(More)
The purpose of this study was to investigate strength, fatigability, and activity of upper limb musculature to elucidate the role of muscular imbalance in the pathophysiology of tennis elbow. Sixteen patients clinically diagnosed with tennis elbow, recruited from a university hospital upper limb orthopedic clinic, were compared with 16 control subjects with(More)
BACKGROUND Therapies for patients with chronic heart failure caused by left ventricular systolic dysfunction have advanced substantially over recent decades. The cumulative effect of these therapies on mortality, mode of death, symptoms, and clinical characteristics has yet to be defined. METHODS AND RESULTS This study was a comparison of 2 prospective(More)
Adaptive muscle activation strategies following a massive rotator cuff tear (MRCT) are inadequately understood, and the relationship among muscles during everyday activities has not been considered. Thirteen healthy subjects comprised the control group, and 11 subjects with a MRCT the patient group. Upper limb function was assessed using the Functional(More)
Studies of normal shoulder function have often failed to consider the inter-relationship between different muscle groups in activities relevant to daily life. Upper limb functional status was assessed in 12 healthy male volunteers using the Functional Impairment Test-Hand, Neck, Shoulder and Arm test (FIT-HaNSA). Electromyography was then used to study the(More)
