practice of stabling. Two main issues are addressed: the generation and distribution of
profits and the factors related to adoption of stabling. A partial...
State and federal aid payments to local governments have grown explosively over the last fifteen years. One reason for this growth is that the donor governments can alter a local government's budget choices through grants. Grants have not remedied social problems, however, because the local governments' responses to grants were...
With too many demands placed on too little water, the Klamath Basin and itsresidents - human and otherwise - are in dire need. There exists a significant opportunityfor mitigation in the purposeful conversion of seasonal wetlands to permanent wetlandsmanaged to increase baseline water storage levels in the Upper Basin. A...
Rural communities will continue to be disproportionately shocked by economic fluctuations. Market forces are likely to lead to the decline of many rural communities and they will need to be economically resilient to survive. This thesis draws on several social sciences and the natural sciences to develop ideas that communities...
The American philosopher and literary critic Kenneth Burke was an "ideologist" (although he never called himself this, and added to that, he spent most of his life avoiding the Marxist term of ideology to describe human "systems" of ideas). Burke instead used the terms "orientation," "rationalization," "perspective." "critical perspective," "way...

Modern science was produced by a Christian society,
and although science has had an effect on Christianity, it
could not itself remain unaffected. In the second half of
the nineteenth century, the subject of evolution was as
much a religious as a scientific issue. The battle line
was drawn and...
There are currently three main models used to describe the pattern of hemispheric specialization (i.e., lateralization) for emotion perception: the right hemisphere hypothesis, the valence model, and the motivational model. Although evidence exists in support of all three, the variation between each pattern of results may be due to differences...
