The purpose of this study is to examine educators' (teachers and school administrators) level of knowledge about the professional role of school social workers and the value that educators place on the functions carried out by social workers as pupil support personnel.

Many teachers known to the investigator had supplemented their teaching incomes by holding part-time jobs. Aware of many such instances, the writer decided to make a survey in San Bernardino County to determine to what extant male elementary school teachers were accepting part-time nonprofessional employment. It was hoped that this study would also determine why those nonprofessional jobs were being accepted by teachers.

The late Miocene Cedar Springs fault system is a high-angle transpressional system in the Silverwood Lake area, western San Bernardino Mountains, southern California. This thesis presents the study of oblique-slip faults with modest amounts of slip, which represent the early stages of fault development by using slip as a proxy for maturity. A structural and geochemical characterization is provided for six fault zones ranging from 39 m of slip to 3.5 km of offset in order to develop a model of fault zone geometry and composition. Basic geometric and kinematic results are provided for an additional 29 small-displacement (cm- to m-scale) faults. The main faults of this study can be divided into the fault core composed of sheared clay gouge and micro breccia, the primary damage zone made up of chemically altered rock with microstructural damage and grain-size reduction, and the secondary damage zone, which is characterized by an increased fracture density relative to the host rock. Although there appears to be a general increase in fault core thickness with increasing slip, the correlation is insignificant when analyzing all faults. Both the primary and secondary damage zones appear to thicken with increased slip on the main fault. Overall, the structure and composition of the faults studied here are similar to those of larger strike-slip and reverse faults. This indicates that the fault core develops early in a fault's history. Subsequent slip appears to be focused along these narrow zones, with some deformation accumulating in the damage zone. Whole-rock geochemical analyses typically show a reduction in the abundance of Na, Al, K, and Ca in the fault core and primary damage zone relative to the host rock. This indicates enhanced fluid-rock interactions in these zones. Calculations of the energy consumed to produce the chemical alteration in the fault core indicate that a considerable amount of the total earthquake energy may be lost to alteration. This thesis concludes that fault processes are similar throughout the different stages of development, and the study of relatively small-displacement faults can therefore be used to understand fault evolution through time and the processes of larger faults in the brittle crust.

Culex quinquefasciatus has been identified as one of the most prominent vectors of West Nile virus (WNV) in Southern California. WNV is a zoonotic disease that is endemic in North America and is known to primarily cause flu-like symptoms in humans, and in rare cases, life-threatening conditions. The goal of this study was to identify which animal species are most frequently fed upon by these mosquitoes in this region. To examine the relationship between blood-feeding patterns and West Nile virus activity in San Bernardino County, the feeding patterns of Cx. quinquefasciatus are determined in a variety of habitat types, which was the primary focus of this study. Furthermore, potential shifts in seasonal blood-feeding patterns of this population of Cx. quinquefasciatus towards increased mammalian feeding was examined. The WNV activity in the county during 2011 was also analyzed. Over 740 Cx. quinquefasciatus samples were collected by West Valley Mosquito and Vector Control District in San Bernardino County during 2011 from 34 different sites. DNA from the bloodmeals was extracted and purified, and a 658-base pair region of DNA located in the mitochondrial gene cytochrome c-oxidase I (COI) was amplified. This was followed by DNA sequencing of the PCR product, and identification of the individual sequences using the Bar Code of Life Data Systems. A total of 683 bloodmeals were successfully identified. These bloodmeals belong to 29 vertebrate species across four different habitats. It was found that species richness was not significantly different between habitats, even though the sample sizes for each habitat varied. Across habitats, the highest percentage of avian bloodmeals were taken from House Sparrows and House Finches. Bloodmeals were identified from five mammalian species which included Humans. A seasonal shift towards increased mammalian bloodmeal prevalence was observed in urban habitats. It was found that WNV activity during 2011 in San Bernardino County was relatively low when compared to the following six years.

The purpose of this study was to identify the youth who do not participate in Independent Living Program (ILP) services and, if possible, to ascertain if any characteristics or factors appear to affect participation in ILP services. The study utilized a quantitative research method to assess ILP participation by extracting data from existing case records via a data extraction form created in conjunction with the San Bernardino County Legislation, Research and Quality Support Services Unit.
