This paper examines social relationships and pressures of contemporary society as shown in Joseph Heller's novel Catch-22. Through a brief study of conceptual limitations within Heller's characters it demonstrates that they exist within a totally self-enclosed system divorced from reality but supported by complex justifications. Within this social matrix is seen the heroic strivings of Yossarian to save a world he believes to have gone mad. As the study progresses, it shows that Yossarian and his friends do not in fact share the same conceptual basis as their apparent society. Their satiric efforts are seen to be useless to a society convinced of its own justifications for evil, and destructive to their own potentialities for human-beingness. The ultimate goal of society is seen to be a physical and spiritual fascism in which no dissent is possible. Escape and death are shown to be the true alternatives for those who would maintain their individuality and ethics. / Arts, Faculty of / English, Department of / Graduate

The primary purpose of my dissertation was to assess two competing models of catch-related attitudes (CRA) of recreational anglers for: 1) valid psychometric measurement, 2) consistency of CRA under different angling contexts, and 3) effect of CRA on angler preferences. Data came from a statewide survey of 6,924 licensed Texas anglers, and a follow-up survey of 1,078 freshwater catfish anglers identified by the statewide survey. I used confirmatory factor analysis to determine that a 4-construct model of CRA provided better fit to the data than a 3-construct model, and was configural and metric invariant across gender, ethnic, and angling context groups indicating cross-group comparisons would be unbiased. However, low factor loadings on several items, and low variance extracted estimates, indicate that current CRA scales require refinement. Additionally, structural equation models found that angler responses to the CRA scale were moderately consistent when measured in generic and species-specific contexts (50-60% shared variance), and the relationship between the two was not consistently moderated by measures of angling avidity. Next, I assessed influence of CRA on angler fishing trip preferences using a stated choice analysis. Results showed that angler choice of hypothetical fishing trips was influenced primarily by travel costs and catch-related trip attributes, and that CRA were significant mediators of angler preferences for associated trip attributes. Finally, I used a latent class state choice model to analyze separate trip choice models for five sub-groups of catfish anglers divided based on their CRA scores. Individual models showed considerable variation in preference for catch-related attributes paralleling strength of each groups’ attitudes towards a given CRA construct. Overall, results indicated that CRA scales are valid predictors of angler preferences and behavioral intentions. Human dimensions researchers studying angler populations will find the CRA scale to be a useful tool to incorporate into predictive models of angler behavior and preferences. Furthermore, fisheries managers should find the CRA scales useful to assess management preferences of an increasingly heterogeneous angler clientele, and aide them in designing management plans that efficiently meet angler needs and catch-related expectations.

Species associations of fifteen major commercial groundfish species in the northeastern Pacific ocean and their spatial and temporal characteristics were studied using Oregon bottom trawl logbook data, 1987 to 1993. Screening procedures were used to remove questionable data from the original logbook files, which resulted in the exclusion of information from 46% of the total available tows. Two multivariate methods, detrended correspondence analysis (DCA) and Ward's method of hierarchical cluster analysis were used to derive the association patterns of species and species groups. A general linear model that was developed for the primary DCA axis suggested that the species associations are strongly correlated with depth, but minimally correlated with the other environmental variables that were examined (latitude, season, and year). The weak correlations between DCA axis 1 and the temporal variables indicate that species associations in the study region are fairly persistent over time. The same multivariate techniques were used to examine possible sampling effects due to changes in the participating trawl vessels that contributed logbook information. Depth and latitudinal distributions of species occurrence in the logbook were similar to distributions derived from National Marine Fishery Service triennial bottom trawl survey. However, the analysis also showed that the depth coverage by the survey is not broad enough to accurately characterize associations among species that are currently subject to commercial fishing activity. / Graduation date: 1998

By-catch is an unavoidable problem in fishery, and the occurrence of by-catch may lead to the phenomenon of discarding. Discarding of non-targeted species will not only result in the losses in economic, but may also damage the resource stock. As the interaction between species exists, the economic costs and the degree of damage derive from by-catch and discarding will become increasingly complicated. The research will start from the assumption of possible interactions between species, investigating that under different interactions between species, the possible influence to the optimal decision of fishermen and resource stocks.

This thesis is an examination of the concept of permeable boundaries as it applies to character and setting in my plays Catch the Wall and 70 Secrets of Marmalade Kittens. The thesis synopsizes each play and catalogues their creation process. It examines the way permeable boundaries can be used to create audience empathy and a wider invitation into the work. The full text of Catch the Wall and 70 Secrets of Marmalade Kittens accompany the thesis essay. / text

Huawei représente un des exemples les plus remarquables de rattrapage réussi par les firmes chinoises. Ayant démarré ses activités en 1987, cette entreprise est maintenant classée deuxième équipementier de télécommunications dans le monde, derrière Ericsson. Dans cette recherche, les sources de compétitivité de Huawei sont étudiées à travers un cas longitudinal incluant tous les évènements majeurs de 1987 à 2011. Ces évènements sont analysés selon 3 unités principales : produit/marché et technologie, relations avec les autres firmes et routines. A cette fin, la littérature sur les ressources (RBV), les compétences dynamiques, les réseaux, et les routines, est mobilisée. La littérature sur le rattrapage technologique et économique est aussi utilisée. Quatre phases sont identifiées et analysées. Ensuite, une analyse longitudinale est réalisée, afin de mettre en valeur les trajectoires de Huawei selon les trois unités d'analyse. Enfin, le style stratégique de Huawei est analysé, afin d'identifier les principes généraux qui ont guidé ses décisions stratégiques au cours de son histoire. Les limitations, les contributions à la recherche à la pratique des entreprises, ainsi que des pistes de recherche sont étudiées. / Huawei is one of the most remarkable examples of sucessful catching-up among chinese companies. It started its activities nearly from scratch in 1987, and is now ranked second telecommunications equipment vendor in the world, after Ericsson. In this research the sources of competitiveness of Huawei are investigated using a longitudinal case study (of arond 100 pages) including all major events from 1987 to 2011. These events are analysed according to three main units: product/market and technology decisions, relationships with other firms, and routines. For this analysis, reference is made to several literature streams, namely the resource-based view, the dynamic capability approach, the network approach and the routines-related literature. The catching-up literature is also mobilised. Four different phases are identified and analysed. Then a longitudinal analysis is conducted for the three analysis untis in order to identify the strategic path of Huawei. Finally, an analysis of the strategic style of Huawei is conducted, in order to identify the general principles that have guided strategic decisions overt the company's history. Limitations, possible contributions to literature and practice are discussed, as well as research directions.

By-catch and wastes from processed fish and shrimp constitute a sizeable portion of commercial fishery landings. This discarded material is potentially valuable, for its content of fish meals and other substances. Fish meals, in particular, are increasingly in short supply for the manufacture of animal feeds, including feeds for farmed fish. Therefore, in this study, various by-catch and by-product meals of marine origin were evaluated with red drum (Sciaenops ocellatus), a carnivorous fish species native to the Gulf of Mexico that has been cultured over the past two decades for stock enhancement as well as for food. Four different kinds of by-catch or by-product meals [shrimp by-catch meal, shrimp processing waste meal, red salmon (Oncorhynchus nerka) head meal, and Pacific whiting (Merluccius productus) meal] were substituted for Special Select™ menhaden fish meal at two different levels (33% or 67% of crude protein) in prepared diets for red drum. Another treatment consisted of shrimp processing waste meal formulated on a digestible-protein basis to replace 33% of the protein from menhaden fish meal. Levels of calcium carbonate were reduced in two additional diets containing Pacific whiting, to evaluate the effects of ash content. Diets were formulated to contain 40% crude protein, 12% lipid, and 3.5 kcal digestible energy/g. Each diet was fed to triplicate groups of juvenile red drum in 38-l aquaria containing brackish water (7 ± 1 ppt) in two separate 6-week feeding trials. Survival, weight gain, feed efficiency, protein efficiency ratio and body composition responses were measured in each trial. Fish fed the by-catch meal at either level of substitution performed as well as fish fed the control diet containing protein solely from menhaden fish meal; whereas, fish fed the shrimp processing waste meal diets did significantly (P ≤ 0.05) worse than the controls, even when fed a diet formulated to be equivalent on a digestible-protein basis. Fish fed the red salmon head meal diet fared poorly, probably owing to an excessive amount of lipid in the diet that tended to become rancid. Overall, by-catch meal associated with shrimp trawling appears to be a very suitable protein feedstuff for red drum.

Magister Scientiae (Biodiversity and Conservation Biology) - MSc (Biodiv and Cons Biol) / The objective of this thesis was to elucidate intra- and interspecific variability in the distribution patterns and diet of the two most common demersal catsharks taken as by-catch by the commercial trawling industry targeting the two Cape hake species off the West and South coasts of South Africa. Samples and data were collected during routine demersal hake biomass surveys conducted by DAFF, with distribution data collected from 1994 to 2015 and stomach content and stable isotope data collected from 2014 to 2015. On examination of the distribution data, Holohalaelurus regani was found to be more abundant on the West Coast and Scyliorhinus capensis was found to be more abundant on the South Coast. Both catsharks were observed to display size-based segregations, with catshark size increasing with depth in both species. Differences in the distribution patterns of male and female H. regani were also noted, with female catsharks inhabiting inshore areas and male catsharks inhabiting offshore areas. The two catsharks appeared to display high levels of dietary overlap, with individuals feeding on the most abundant crustaceans and cephalopods caught as by-catch in the trawl on each coast.
