In the US, a disease is classified as rare if it affects less than 200,000 individuals a year. Despite considerable similarities, individuals with rare diseases (RDs) report worse life quality and satisfaction with life (SWL) than those with common chronic conditions. One potential avenue to increase SWL is through improving...
An inextricable link exists between dams and human development in the Pacific Northwest, but they can fragment rivers and reduce genetic connectivity for freshwater and anadromous fishes. Since the early-twentieth century, a series of hydropower and irrigation dams on the mainstem Klamath River, California, has fragmented migratory corridors and eliminated...
Level of aspiration plays a part in achievement motivation which
supports teaching/learning in motor performances. In the past,
females reported poorer ability in performances, set lower levels of
aspiration, and had lesser achievement motives than males (Crandall,
1969; Stein & Bailey, 1973; Sumner & Johnson, 1949). Some researchers
found there...
About one-quarter of the U.S. adult population lives with a disability, yet ableist presentations of disability as a tragedy in need of a cure (i.e., the medical model) continue to predominate, even in higher education. Previous, qualitative research showed that people with disabilities (PWDs) desire changes in individual and societal...
