The growing use of light-frame wood trusses in the
residential and commercial construction has generated the
need for general analysis procedures for predicting
deformations and ultimate load of truss-plate joints, which
are the basis for accurate evaluation of structural
performance and design of complete truss assemblies. This
dissertation was aimed...
The conventional method for determining lumber strength depends
on visual evaluation by lumber graders which often results in
undergrading of lumber. Nondestructive proof testing is used less
often and provides for only estimates of elastic moduli of elasticity
and rupture. The evaluation of nondestructive variables such as
proportional limit (PL)...
Every year thousands of families experience a major
life-changing event when they are torn from their
homeland and become refugees. Little is known about how
the refugee experience impacts the family and how members
perceive it affects their sense of family identity. The
construct of family identity as proposed by...
Infestation with nonnative, “exotic” lice was first noted in Washington black-tailed deer (Odocoileus hemionus columbianus) in 1994 and has since then spread throughout the western United States. In California, infestation with the exotic louse Damalinia (Cervicola) sp. was first detected in black-tailed deer from northern California in 2004, and, in...
This thesis outlines dominant ideologies and practices that affect women's authority in the urban social milieu of north India. Theories that consider the causes of social stratification by gender as well as social movement patterns are useful for understanding the durability of gender roles. The utility of these theories for...
Spatial capture-recapture (SCR) is employed for estimating abundance and density of species, particularly those that are cryptic or solitary, and evaluating how population density varies with habitat. However, it is uncertain whether estimates are biased when applied to species that aggregate, such as elk (Cervus canadensis). Wildlife managers in the...
An integrated model combining a wildlife population simulation model, and timber harvest and growth models was developed to explore the tradeoffs between the likelihood of persistence of a wildlife species and timber harvest values on a landscape in the Central Oregon Cascades. Simulated annealing, a heuristic optimization technique, was used...
