13. Processos produtivos e trabalho-educação : a incorporação do caboclo catarinense na industria madeireira
The object theme of the present study is a population of caboclos that absorbed as manual workers in the saw-mills which were mounted in the highland region of Santa Catarina since 1950. The abundance of araucaria (native kind of pine) the opening of markets, and the corroboration of other industrial exploration conditions encouraged a great crowd of small e

14. Evidence for Processing Stages in Skill Acquisition: A Dual-Task Study
We investigated the changes of resource demand during the acquisition of a sensorimotor skill, namely the tracking of a visual target under reversed visual feedback. This acquisition task was performed alone or concurrently with one of four manual reaction-time tasks as loading tasks, designed to tap different computational resources. As expected, we found t

15. Use of flexible plastic film isolators in performing potentially hazardous necropsies.
A number of necropsies were performed with the body completely isolated in a flexible film isolator in order to determine the practicability of such a method in protecting the post mortem room staff from the risk of infection from the corpse. It is considered that necropsies can be carried out using such an isolator without hindrance to either manual skill o

16. Manual and Automated Instrumentation for Identification of Enterobacteriaceae and Other Aerobic Gram-Negative Bacilli
Identification of gram-negative bacilli, both enteric and nonenteric, by conventional methods is not realistic for clinical microbiology laboratories performing routine cultures in today's world. The use of commercial kits, either manual or automated, to identify these organisms is a common practice. The advent of rapid or “spot” testing has eliminated t

17. Impairments in the learning and performance of a new manual skill in patients with Parkinson's disease.
Twelve patients with Parkinson's disease learned two novel skills in which they had to track a target by moving a joystick. In task 1 they had to learn to anticipate the movements of a semi predictable target. In task 2 they had to learn a novel control system in which the movements of the joystick were mirror reversed in relation to the computer screen. On

18. Changes in Performance Monitoring During Sensorimotor Adaptation
Error detection and correction are essential components of motor skill learning. These processes have been well characterized in cognitive psychology using electroencephalography (EEG) to record an event-related potential (ERP) called error-related negativity (ERN). However, it is unclear whether this ERP component is sensitive to the magnitude of the error

19. Classification of support staff in a consortium medical library: a case study.
A representative committee of Houston Academy of Medicine-Texas Medical Center Library staff and faculty, under the direction of the library administration, successfully redesigned a job classification system for the library's nonprofessional staff. In the new system all nonprofessionals are assigned to one of five grade levels, each with a corresponding sal

20. Acute neurobehavioural effects of toluene.
An acute inhalation chamber study of 42 college students was performed to investigate the relation between exposure to 0, 75, and 150 ppm of toluene and changes in central nervous system function and symptoms. Paid subjects were exposed for seven hours over three days. Verbal and visual short term memory (Sternberg, digit span, Benton, pattern memory); perce

21. Occupational exposure and 12-year spirometric changes among Paris area workers.
A follow-up study over 12 years was conducted among 556 men aged 30 to 54 in 1960 and working at that time in factories around Paris (France). Various occupational exposures were recorded at the time of the 1960 survey after a technical study of each workplace. The annual rate of decline of FEV1 during 12 years was estimated for each subject from the measure

22. Acute behavioural comparisons of toluene and ethanol in human subjects.
A comparison of toluene and ethanol (EtOH) induced changes in central nervous system (CNS) function and symptoms were evaluated in two studies, and when possible the effects of toluene were expressed in EtOH equivalent units. The toluene concentrations were 0, 75, and 150 ppm, bracketing the American Conference of Governmental Industrial Hygienists threshold
