Fatigue in cerebral palsy: a critical review.

Objective: Fatigue contributes to the deterioration or cessation of walking ability in adults with cerebral palsy (CP). However, conflict exists as to its role. Studies involving functional tasks reported increased, and earlier onset of, fatigue in CP whereas laboratory studies have reported individuals with CP to be more fatigue resistant than their peers. Methods: A critical review of the literature related to fatigue in CP was conducted. Results: This review describes factors that contribute to the observed fatigue resistance in laboratory tasks and how a decreased force-production in CP can result in higher energy expenditure to perform the same amount of work as their peers. Conclusion: More research regarding the process of fatigue and recovery for individuals with CP is needed; specifically studies that focus on functional movements requiring the integration of the whole body, thereby stressing the neuromuscular system in a different way than previously explored

Managing Cultural Resources On The Alaska Peninsula

Twentieth-century cultural resources provide physical evidence of human relationships with a landscape that has shaped the wilderness areas we know today. These cultural resources enrich the meaning of an area as wilderness, but also present multiple management challenges surrounding visitor use in designated wilderness areas. The National Geographic Society Katmai Expeditions of the 1910s present a case study of how historic trails and their associated artifacts interact not only with present issues toward the dual-enforcement of the National Historic Preservation Act and Wilderness Act, but also with the management of visitor use along a corridor containing relatively recent traces of historically significant activities and events. This study draws on the findings of a 2 018 expedition identifying convergence of a historically significant trail w ith a popular path for backpackers through the Katmai Wilderness and explores the importance of cultural resources in long-distance trail planning and cultural resource management in designated wilderness

Assessment of the wintering area of Red Knots in Maranhão, northern Brazil, in February 2005

To assess population size and the conservation status of the Red Knot Calidris canutus rufa population in Maranhão, N Brazil, an aerial census and field studies were conducted in February 2005. The aerial count showed a population of 7,575 Knots, which is down about 600 from a previous census in the 1980s. However, the count for all shorebird species combined was only 24,000 compared to 198,600 in the 1980s, paralleling a world-wide trend of population decline in shorebirds. Resightings of colour-banded knots confirmed that this is a separate population from the larger wintering population in Tierra del Fuego. All species of shorebirds captured in Maranhão were found to be infested with feather lice and mites. Body masses of knots in Maranhão were significantly lower than in Tierra del Fuego, and about half the birds were below the hypothesized fat-free mass of the species. Blood and feather samples were taken from 38 Knots for subsequent assessment of virus loads, and for detecting sites where primary feather moult had occurred. This will enable us to establish whether significant mortality is associated with pathogen loads and the energetic demands of delayed moulting. The small size of the Maranhão population and the loss of another 13,000 knots this winter from the Tierra del Fuego population means that both are now endangered. Brochures on the need for Red Knot conservation were designed and printed, and have been circulated among fishing communities and school classes in Maranhão.Fil: Baker,Allan J..

Defining alcohol-related phenotypes in humans. The Collaborative Study on the Genetics of Alcoholism.

Alcoholism is a disease that runs in families and results at least in part from genetic risk factors. The Collaborative Study on the Genetics of Alcoholism (COGA) is a Federally funded effort to identify and characterize those genetic factors. The study involves more than 1,000 alcoholic subjects and their families, with researchers conducting comprehensive psychological, physiological, electrophysiological, and genetic analyses of the participants. These analyses have identified several traits, or phenotypes, that appear to be genetically determined, such as the presence of alcohol dependence, the level of response to alcohol, the presence of coexisting depression, or the maximum number of drinks a person consumes per occasion. Genetic analyses have identified regions on several chromosomes that are associated with these phenotypes and need to be studied further

Genetic diversity fuels gene discovery for tobacco and alcohol use

Tobacco and alcohol use are heritable behaviours associated with 15% and 5.3% of worldwide deaths, respectively, due largely to broad increased risk for disease and injur

Reflective Perspectives of Host and Guest Participants of an International Professional Development Experience

Global competence is a skill set that has become a necessity in every discipline in the agricultural sciences. With an increasingly diverse student population in our school systems coupled with an increasingly complex global agrisystem, now more than ever we need globally competent educators and learners to develop a globally competent workforce and society. A common intervention in cultivating global competency is the study abroad immersive experience for the traveling participants, but little is known about the global competency gains in hosting individuals. The immersive study abroad experience provided the opportunity for school-based agricultural educators (both candidates and practicing educators) to engage in a four-week experience with their Malaysian counterparts exploring the interconnected nature of culture, agriculture, and education. Throughout the experience the participants engaged in daily structured reflection sessions using the TIPS method. Journal entries were coded and analyzed for both Malaysia and United States participants. Participants from both countries respectively became more globally competent educators and learners
