A molecular system was developed and tested to efficiently analyze algal communities in river water samples. Polymerase Chain Reaction (PCR) primers were designed to amplify the 18S rRNA gene of certain taxonomic groups of freshwater algae; there was limited success in specific amplification. Additionally, a primer pair utilizing both the 16S plastid gene and the 16S rRNA gene was tested with success, amplifying both prokaryotic and eukaryotic algae while excluding other taxonomically similar organisms. The terminal restriction fragment length polymorphism (TRFLP) fingerprinting method, which has been used in previous studies to examine prokaryotic community structure, was modified with the successful algae primers to selectively fingerprint all algal groups in two San Joaquin River water samples. Triplicates of two TRFLP profiles have been generated and terminal restriction fragments (TRFs) have been assigned to specific algal species.

The general purpose of this study is to turn to the possibilities of a second focus of research into the adoption process, that is, to what can be learned about the natural mother. The particular purpose of this study is threefold: (1) to identify the socio-economic characteristics of those women contacting a public adoption agency for the placement of their children with prospective adoptive families; (2) to identify and examine the sociological factors which appear to influence the natural mother to wither keep or surrender her child; and (3) to determine if the women contacting the agency in 1969 represent the same socio-economic characteristics as those women who contacted the agency in 1959.

The purpose of this study is to find evidence that will show whether or not there is a need for a school housing program in the small rural school districts in San Joaquin County, California. The study is justified by a comparison of the present conditions of the schools to a set of standards for good schoolhouse construction which have been established by noted authorities and educators in the field.

Consultants in elementary education use a variety of techniques in their work with teachers to improve instruction in schools. The problem with which this study will be concerned may be stated as follows: What supervisory techniques are employed by San Joaquin County consultants in elementary education in their efforts to improve instruction in schools that receive direct instructional supervision? The specific purposes of this study are: (1) To define the role of the elementary consultants in San Joaquin County.; (2) To identify the supervisory techniques that the consultants employ in their work with teachers.; (3) To survey the use of supervisory techniques with respect to frequency, number and length of supervisory visits, subject matter, categories of instructional responsibilities, experienced and inexperienced teachers, and judged success.; (4) To compare the scope of the supervisory techniques employed by the consultants with that contained in the literature, and with local practice.; (5) To make recommendations for improvements or changes that the study may show to be desirable.

This study deals with the tenure of teachers of the fifty-nine rural schools of San Joaquin County that have from one to twenty teachers each. The problem is to find and record the factors that influence teachers to continue teaching over a period of years in certain rural schools of San Joaquin County, rather than moving about.

The San Joaquin Valley is regarded as one of the most productive agricultural regions in the world. This extensive agriculture has, however, caused extensive pollution of both ground water and surface water. This thesis develops a hydrologic model of the surface and ground waters of the San Joaquin Valley. Such modeling is useful in the development and implementation of water quality regulations such as Total Maximum Daily Loads (TMDLs). A properly validated watershed simulation model can supplement data collection and can account for watershed characteristics including topography, soils, climate, land cover, anthropogenic activities, as well as simulate watershed responses including streamflow and contaminant concentration at detailed spatial and temporal scales. Models can be used as a decision support tool to manage complex agricultural watersheds such as the San Joaquin Valley. Once developed, such watershed simulation models can be used to identify contaminant source areas, locate hot-spot areas that have high pollution risk, identify optimal monitoring sites, and determine best management practices to cost-effectively reduce pollution. As a step towards developing a model as a decision making tool, the objective of this study is to appraise effectiveness of a widely used watershed simulation model known as Soil and Water Assessment Tool (SWAT) to simulate hydrology of the San Joaquin Valley watershed. For this thesis SWAT was successfully calibrated for streamflow at several locations in the watershed, thus demonstrating the capability of the model to represent the complex, snow-driven hydrology of the San Joaquin Valley watershed including dams and reservoirs located in the mountains, and agricultural activities and flow diversion systems in the valleys. Calibration of sediment and nitrate loadings in the surface waters were also attempted; the results were, however, less than convincing compared to stream flow calibration. Future studies are recommended to improve accuracy of the water quality predictions and to evaluate long-term effectiveness of various watershed management policies in improving surface water and groundwater quality in the San Joaquin Valley. The hydrology model developed in this study can be used as a foundation for future studies that focus on water quality.
