Analysis Of Chilean Fisheries Expansion Alternatives, Luis Alberto Adriasola

Open Access Dissertations

This dissertation investigates the expansion of the Chilean fisheries focusing on the processing and marketing activities for seven fish species that represent over 90% of the catch and for two groups of the remaining fish species. A review is made of the current condition of the Chilean fisheries, its expansion potential and some possible expansion alternatives. It is established that there exists an ample potential for the expansion of the catch and physical production of fishery commodities. A model is developed to characterize the economic system formed by the fisheries extractive and related activities and assess the profitability of investment …

Ecology Of Parathemisto Libellula And P. Pacifica (Amphipoda: Hyperiidea) In Alaskan Coastal Waters, Bruce L. Wing

Open Access Dissertations

The planktonic amphipods Parathemisto libellula and P. pacifica coexist in coastal waters from southeastern Alaska (56° N) to the south-eastern Chukchi Sea (70° N). Observations on distribution, reproductive cycles, diets, metabolism, and starvation tolerance contribute to understanding this case of congeneric coexistence.

Samples were collected monthly from September 1969 to October 1970 in southeastern Alaska, from May to September 1969 in the southeastern Bering Sea, and in September-October 1970 in the southeastern Chukchi Sea. Respiratory metabolism and starvation tolerance were studied in winter-caught amphipods from southeastern Alaska.

Both species consistently occurred above 300 min southeastern Alaska. In the southeastern Bering …

The Effects Of Self-Imposed And Externally Imposed Rewards Of Children's Intrinsic Motivation, Douglas Lee Schooler

Open Access Dissertations

An experiment was designed to compare the effects of self-imposed, externally imposed, and a no reward control, on children's interest in both a high and low listening task. A hypothesis grounded in personal control theory predicted that self-imposed rewards would increase subsequent task interest, whereas externally imposed reward would interact with initial task interest and would yield a decrease in interest for the high interest task and an increase in interest for the low interest task. A secondary hypothesis predicted that children would self-reward with greater magnitude on the low interest task. The subjects, 48 boys and 48 girls from …

Cognitive Complexity Of Clinical Psychology Students In Relation To Their Evaluation Of Contributions To Psychology, Dannel Hussey Starbird

Open Access Dissertations

The present study addressed the possibility that cognitive-complexity (Bieri, et al., 1966) relates to the

relative breadth with which clinical psychology students assess relevant contributions to psychology. A Q sort measure of view of psychology was devised using the names of 30 contributors to clinical and 30 contributors to nonclinical psychology. It was proposed that clinical psychology students with a narrow view of psychology would place greater emphasis upon clinical contributors, and that this tendency would be positively correlated with their level of cognitive-complexity. Secondly, it was hypothesized that there are not sex differences in cognitive-complexity, and that measures of …
