This study examines the county courthouses of Arkansas with the purpose of discovering certain qualities which they possess as architecture. Stylistic influences are identified, as are influential architects, periods of building activity, and characteristics of age and condition. An historical overview provides information concerning nationwide trends in public architecture over the last century, allowing observations as to the effects which national and regional tastes had on Arkansas' county courthouse builders. It is concluded that Arkansas' county courthouses reflect, to some extent, the stylistic preferences and backwardness of southern and rural courthouses, respectively. The Georgian Revival is identified as the most popular style for courthouses still in use, although the most active building period is found to be the 1930s, when WPA design specifications dominated Arkansas courthouse architecture.

The feeding ecologies of leaf pack-associated systellognathan stoneflies were examined from 6 June 1980 21 May 1981. Species composition, seasonal abundance, nymphal growth, feeding habits and mouthpart morphology were determined for the eight dominant stonefly species. Prey preferences and predator-prey size relationships were also examined for omnivorous and carnivorous species. Foregut analysis from 2860 individuals indicated opportunistic feeding on the most abundant prey insects, usually in proportion to prey frequency. Feeding preference studies generally indicated random feeding on major prey groups. Prey and predator sizes were usually highly correlated (p<0.01), with predators expanding their prey size thresholds with growth. The potential for competition between sympatric stoneflies for prey is discussed.

The primary purposes of this study were to assess the understanding and attitudes of teachers, to determine the interaction effects of certain variables, and to determine if there is a correlation between understanding of economic concepts and attitude toward economic education. The problem of the study was an assessment of the attitudes toward and understanding of economic concepts held by secondary school teachers in Arkansas who taught economics or economics-related subjects.
