The terms "core" and "periphery" have a long history of use for describing regional variability in the archaeological record. Contemporary theories for the late prehistoric in the Greater Southwest often follow this tradition, postulating underlying social processes that created this division. This dissertation examines the assumptions and the evidence for theories of long-distance social interaction by considering the prehistory of the Northern Sierra, a region in the south-central Greater Southwest located in northwestern Chihuahua, northeastern Sonora, southwestern New Mexico, and southeastern Arizona. Paquime (sometimes called Casas Grandes) in Chihuahua is widely considered to be the core of late prehistoric developments in the Northern Sierra. The history of research and interpretation of the region are carefully considered, an analysis that demonstrates the inadequacies of current data and theory. New frameworks will be needed to resolve disputed issues. Towards this end, evidence of interaction at Paquime is examined by analyzing the quantity and distribution of nonlocal ceramics within the site. These probable exchange items are found to be relatively rare and their distribution diffuse, indicating acquisition was largely casual and infrequent. Attention is then focused on the postulated periphery by examining the upper San Bernardino Valley in the extreme southeastern corner of Arizona. Data collected for this examination includes survey within the Valley and excavation of the late prehistoric Boss Ranch Site (AZ FF:7:10 (ASM)). The interpretive concerns that are addressed include (1) population movements, (2) external influences on settlement systems, (3) trade and interaction, and (4) the influences of subsistence systems. The analysis revealed no evidence of population intrusion from the "core" and few aspects of local material culture that could be ascribed to Paquime. Exchange items are rare, and the probable sources include many areas besides the zone around Paquime. Furthermore, excavation data suggest that settlements may have been occupied repeatedly for short periods. This undermines notions of stable core and periphery interaction by indicating the absence of surplus crops, stable social alliances, and hierarchical settlement systems in the region.

This study compares a face-to-face format of teaching with closed circuit interactive television courses offered to off campus students at California State University, San Bernardino. The study provides comparisons of student satisfaction and student performance between the two mediums.

East Valley Water District is located in San Bernardino, California which is approximately 50 miles east of Los Angeles. In order to meet future water demands, East Valley Water District plans to increase recharge activities in the forebay area of the San Bernardino groundwater basin and expand wellfield operations immediately downgradient. Three possible recharge and wellfield designs were under consideration with annual recharge rates increasing 10,000 to 20,000 acre-feet/year in the Santa Ana spreading basins. Approximately four to five new production wells pumping an equal quantity of groundwater have been proposed. A two-dimensional finite element groundwater flow model was constructed and calibrated to reproduce historical water level data for the year 1945. They calibrated model was applied to simulate the hydrologic effects of each of the three designs over a ten-year period.

The focus of this report and the study for which it was written involves two specific types of user charges: Building permit fees are fees that cover the cost of administering the document (the building permit) and the cost of inspecting the construction for which the permit was issued. This report examines the issues, both legal and procedural, surrounding regulatory fees and their effects on building fees within the City of San Bernardino. As elements of the larger study, various smaller studies such as time and motion studies of the building inspector's activities and fully Burdened Hourly Rate Study were completed.
