Model selection procedures often use a fixed penalty, such as Mallows' C p , to avoid choosing a model which fits a particular data set extremely well. These procedures are often devised to give an unbiased risk estimate when a particular chosen model is used to predict future responses. As a correction for not including the variability induced in model(More)
Peduncular hallucinosis usually presents as a visual disorder and is often a genuine hallucination associated with mesencephalic lesions. A 62-year-old woman with trigeminal neuralgia underwent microvascular decompression for facial pain through a lateral suboccipital approach. The pain completely disappeared after surgery, but a visual hallucination(More)
This study investigated the effect of different types of distractions related to use of a hands-free phone on driving performance. The study used three types of verbal distractors: casual conversation, simple arithmetic number guessing, and number adding, in the phone conversation. 12 adults were instructed to follow a lead vehicle on a closed-course(More)
In this study, the hierarchical model of achievement motivation [Elliot, A. J. (1997). Integrating the ''clas-sic " and ''contemporary " approaches to achievement motivation: A hierarchical model of approach and avoidance achievement motivation. is used to investigate the motivational mechanism behind the relationship between fear of failure and(More)
Work-related musculoskeletal injuries are often associated with overexertion of the body at work. The manual materials handling activity of lifting is a major source of work-related musculoskeletal disorders. Biomechanical evaluation offers useful information about the physical stress imposed on the worker's body joints; however, biomechanical analysis is(More)
This work investigated how wearing a new design of back belt affects erector spinae activity, hand force, and body stability. The belt was first tested with static holding tasks and found to significantly decrease the back muscle activity. Actual lifting tasks were further carried out to test the effect of the belt. Ten male subjects performed a symmetric(More)
It has been suggested that estrogen supplementation can augment the treatment effects of typical antipsychotic medication. We report the use of estrogen supplementation for four female chronic inpatients. These patients were diagnosed with schizophrenia or schizoaffective disorders and were treated with atypical antipsychotics. Premenstrual exacerbation of(More)
Microvascular decompression by suboccipital craniectomy often cures medically untreatable trigeminal neuralgia. However, pain involving the same distribution persists in a few patients despite surgical treatment. In two cases, one with postherpetic pain and the other with tic douloureux, the author used the radiofrequency lesion technique in the dorsal root(More)
