The title of this volume promises more than the content delivers. The heart of the book is information from Ward's 1992 University of Chicago doctoral dissertation, which focused on the social and cultural reasons leading to students dropping out of school. Her first two chapters provide a good review of research on dropouts and Indian education; the following six focus on the results of her 1987-1989 study of 698 Northern Cheyenne, Crow, and white high school students attending the Colstrip Public, St. Labre Catholic, and Busby Tribal Schools in Montana. Fifty-two percent of the students in this study were Indian, with a dropout rate of 45% .

The October 1998 flood on the upper Guadalupe River system was produced by a 24-hour precipitation amount of 483 mm at one station, over 380 mm at several other stations, and up to 590 mm over five days, precipitation amounts greater than the 100-year storm as prescribed in Weather Bureau Technical Papers 40 (1961) and 49 (1964). This study uses slope-area discharge estimates and published discharge and precipitation data to analyze flow characteristics of the three major branches of the Guadalupe River on the Edwards Plateau. The main channel of the Guadalupe has a single large flood-control structure at Canyon Dam and five flood dams on the tributary Comal River. On the upper San Marcos River there are five detention dams that regulate 80% of its drainage. The Blanco River, which has no structural controls, generated a peak discharge of 2,970 m3/s from a 1,067 km2 basin. Downstream of Canyon Dam, the Guadalupe River generated a peak discharge greater than 3,000 m3/s from an area of 223 km2. The event exceeded the capacity of both the Comal River and San Marcos flood-control projects and produced spills that inundated areas greater than the 100-year floodplain defined by the Federal Emergency Management Agency.

In social species, breeding system and gregarious behavior are key factors influencing the evolution of large-scale population genetic structure. The killer whale is a highly social apex predator showing genetic differentiation in sympatry between populations of foraging specialists (ecotypes), and low levels of genetic diversity overall. Our comparative assessments of kinship, parentage and dispersal reveal high levels of kinship within local populations and ongoing male-mediated gene flow among them, including among ecotypes that are maximally divergent within the mtDNA phylogeny. Dispersal from natal populations was rare, implying that gene flow occurs without dispersal, as a result of reproduction during temporary interactions. Discordance between nuclear and mitochondrial phylogenies was consistent with earlier studies suggesting a stochastic basis for the magnitude of mtDNA differentiation between matrilines. Taken together our results show how the killer whale breeding system, coupled with social, dispersal and foraging behaviour, contributes to the evolution of population genetic structure.

Previous studies of the Social Gospel movement have acknowledged the fact that Social Gospelers were involved in multiple social reform movements during the Gilded Age and into the Progressive Era. However, most of these studies have failed to explain how the reform experiences of the Social Gospelers contributed to the development of the Social Gospel. The Social Gospelers’ ideas regarding the need to transform society and their strategies for doing so were largely a result of their personal experiences as reformers and their collaboration with other reformers. The knowledge and insight gained from interaction with a variety of reform methods played a vital role in the development of the ideology and theology of the Social Gospel. George Howard Gibson is exemplary of the connections between the Social Gospel movement and several other social reform movements of the time. He was involved in the Temperance movement, was a member of both the Prohibition Party and the People’s Party, and co-founded a Christian socialist cooperative colony. His writings illustrate the formation of his identity as a Social Gospeler as well as his attempts to find an organization through which to realize the kingdom of God on earth. Failure to achieve the changes he desired via prohibition encouraged him to broaden his reform goals. Like many Midwestern Social Gospelers Gibson believed he had found “God’s Party” in the People’s Party, but he rejected reform via the political system once the Populists restricted their attention to the silver issue and fused with the Democratic Party. Yet his involvement with the People’s Party demonstrates the attraction many Social Gospelers had to the reforms proposed in the Omaha Platform of 1892 as well as to the party’s use of revivalistic language and emphasis on producerism and brotherhood. Gibson’s experimentation with a variety of ways to achieve the kingdom of God on earth provides new insight into the experiences and contributions of lay Social Gospelers. Adviser: Kenneth J. Winkle
