success as experienced in a learning environment, and its association
with self esteem. The relationships between pretreatment-self
esteem, posttreatment-self esteem, and perceived success experienced
in a five-week clothing construction course were investigated.
Measures of perceived sewing ability, perceived success,
and course...
In their modern context questions of heredity have come to be
closely aligned with theories of evolution because all such theories
require the presence of heritable variation. Thus the need for an
understanding of a source of variation and a mechanism for its inheritance
became very apparent with the general...
In the face of environmental stressors, change is imperative for species to remain in place. The nature and degree of this change is of great interest, as it sheds light into the ways in which species respond to ecological and habitat change and may continue to respond during periods of...
Introduction: Sports bras offer different levels of breast support and allow for a wide
range of vertical breast motion. Excessive breast motion during exercise causes
discomfort and may discourage participation in regular exercise. Inadequate breast
support may lead to adaptations in a woman's running mechanics. Purpose: This study
aimed to...
Ship turnaround time at a marine containerport is an important
measure of the port's efficiency and attractiveness. Both the speed
and quality of load planning affect the length of turnaround time
considerably. Past attempts at computerizing the load planning
function have been unsatisfactory and have not reflected the port's
objective...
In the United States, falls are the leading cause of unintentional death with one of every three people 65 years and older falling each year. Falls account for approximately 95% of hip fractures among older adults and falls to the side predominate hip fracture related falls in this population. However,...
Published literature about six Pacific Northwest stream systems was contrasted
to provide a regional perspective on channel response to disturbance. This
investigation was prompted by a combination of recent environmental legislation,
mounting social pressures to plan projects at a drainage basin scale, and the difficulty
in defining and predicting the...
The Aleutian tern (Onychoprion aleuticus) is a species of high conservation concern in Alaska due to large declines at known breeding locations since the 1960s. Due to the small population size and ephemeral behavior of this species on the nesting grounds, there is little basic biological information available and data...
This study was designed to assess chiorpyrifos exposure of a group of farmers by determining internal dose associated with a given application of this insecticide. This involved the monitoring of urinary levels of 3,5,6 trichloro-2-pyridinol (TCP), the major metabolite of chlorpyrifos. Incidental exposure was evaluated by determining the levels of...
Quinolinate (QUIN) is an endogenous neurotoxic product of the kynurenine
pathway of tryptophan metabolism. Quinolinate is a selective agonist of the NMDA
family of glutamate receptors and, as such, may play a role in the pathology of a number
of major central nervous system (CNS) disorders. These include both chronic...
