The Oregonian: A Portrayal of the University of Oregon

16 p.The University of Oregon in the sixties was a representative of the changing attitude among young people across the country. Growing hair long, experimenting with sex and drugs, and questioning all authority was among the revolutionary actions. American youth protested decisions of the government, specifically with constant controversy over the war. Violence was all around as Martin Luther King Jr. and Robert Kennedy were both assassinated, the U.S. Army killed hundreds of civilians in South Vietnam, and black athletes were protested at the Mexico City Olympics. The once conservative and strict attitude between the Deans of Men and Women and the enrolled students, quickly transformed to a liberal and rebellious attitude. Civil rights were a hot topic and on campuses across the country, the specific issue of student rights was debated. Many Eugene, Oregon locals witnessed first-hand the protests of the students at the University. However, most other Oregonians relied on the media to relay the information and state of the University to them in an objective and factual manner. The largest state-wide newspaper, based out of Portland, was The Oregonian. Specifically studied here are The Oregonian articles reporting on the University of Oregon incidents during April of 1970 as well as a generalized study of how mass media affects public opinion. This Portland publication used loaded language and photographs to frame incidents at the University of Oregon, and thus to persuade readers across the state that the Eugene campus was a place of liberal chaos

Local and regional patterns of transport, dispersal, and exchange in coastal fishes

xix, 240 p. OIMB PhD DissertationA print copy of this title is available through the UO Libraries under the call number: SCIENCE QL623.2 .M55 2004Ocean transport processes affect larval dispersal and influence survival and exchange among populations. Cross-shelf and alongshore transport are known to be important but it is not understood which mechanisms are dominant or whether similar mechanisms regulate transport to and between coastal and estuarine areas. Time series, chemical, and genetic analyses were used to provide information on transport, dispersal, and exchange in coastal fishes. Time series analyses of high frequency (every 1–2 d), short-term (4 mos) light trap collections were completed to compare species' abundances, examine potential transport mechanisms, and document exchange between the coastal ocean and an adjacent estuary. Peak abundances of juvenile fish in the estuary occurred 0 to 4 d after peaks at the outer coast, which indicate that estuarine ingress was a two-stage process. Next, a long-term (3¾ yr) time series of light trap collections within Coos Bay, Oregon was analyzed. Thirty-eight taxa of larval and juvenile fishes were collected. Within the estuary, fish were most abundant during downwelling but there was little evidence for wind-driven transport. Tidal periodicities in fish abundances were observed in the estuary and at the outer coast, which indicate shoreward transport and estuarine ingress may have occurred via selective stream tidal transport and/or internal tides and bores. Thirdly, the otolith elemental composition of black rockfish (Sebastes melanops), collected at sites 120–420 km apart, was examined at various positions along the otolith growth axis to estimate relative extents of larval dispersal and adult movement. Geochemical otolith signatures accurately classified 67% to 81% of individuals to collection location throughout their life. A probable explanation is that individuals from geographically distinct locations never mixed and possibly did not disperse long distances as larvae, which may contribute to population divergence. DNA microsatellite analysis identified significant genetic differences (FST = 0.018 ± 0.004) between adults from Oregon and Washington, providing corroborative evidence for limited larval dispersal. Lastly, spatial and temporal variation in otolith elemental composition of staghorn sculpin (Leptocottus armatus), collected in Oregon and California estuaries, was examined to further evaluate the utility of otolith microchemistry in determining movements of individual fish
