This monograph is focused around the controversy in the economic literature regarding the effects of income changes on labor force participation. In particular, this controversy arises from the opposing hypotheses: the "additional worker" and the "discouraged worker." Each hypothesis predicts different behavior in response to falling income or rising unemployment....

Pyrosomes are colonial pelagic tunicates that have fascinated marine biologists for over a century. Their name comes from the “fiery” bioluminescence that luminous organs produce at night time. Blooms of pyrosomes, identified as Pyrosoma atlanticum (Peron, 1804), have recently appeared in the North Pacific Ocean, prompting questions about environmental factors...
In fuel pin fabrication, there is no assurance that a
fuel pellet will be loaded concentrically. Therefore,
azimuthal variations exist in the temperature field giving
rise to asymmetry in the neutron flux distribution and pin
stresses. Calculations must be made to determine the two
dimensional temperature profile which may then...
In recent years there has been an increased emphasis being placed on the study of natural convection in various systems. The majority of studies have been concerned with concentric geometries. The studies oriented toward eccentric geometries have been very few and very specialized. The major emphasis of the studies have...
This study investigated the opinions of bicyclists/pedestrians
regarding how safe from a bicycle traffic injury they felt while on
campus. Most earlier studies had been concerned with the taxonomy
of bicycle/pedestrian accidents. Because of the paucity of
research on attitudes of bicyclists and pedestrians, this research
was undertaken.
The survey...
Large-scale poisoning events are common to scavenging bird species that forage communally, many of which are in decline. To reduce the threat of poisoning and compensate for other persistent threats, management, including supplemental feeding, is ongoing for many reintroduced and endangered vulture populations. Through a longitudinal study of lead exposure...
Flux estimates show that upward mixing of the deep-water nitrate pool accounts for more than 85% of the total new nitrogen input to the euphotic zone of Crater Lake. Because measured primary productivity (360 mg C m-2 d-1) is 10–30 times higher than a level supported solely by the input...
