Crisis or failure of hegemonic masculinities in David Lodge’s Campus Trilogy

This bachelor’s thesis examines the crisis of hegemonic masculinities in David Lodge’s Campus Trilogy. In the course of the thesis, I demonstrate that the male characters in the novels aspire to hegemonic ideals of masculinity, but that ultimately most of them fail in their aspirations. However, I also show that this does not lead to the abandonment of this pursuit, but merely to its reformulation and a continued attempt of male characters to aspire to this reformulated ideal. In order to achieve this, I conduct a close reading of the novels and based on this, first determine the predominant types of hegemonic masculinities in each novel, and then whether certain characters aspire to these hegemonic ideals. Next I analyze whether or not they are successful. This analysis is chiefly based on the sociological concept of hegemonic masculinities developed by Connell. With the help of this concept, this thesis shows that several types of masculinities can be identified in the novels and that these exist in hierarchical relation to each other. Furthermore, it shows that these aspirations and the ideals themselves are always prone to crises that are brought on by societal changes in their environment. However, it is also demonstrated that in most cases these crises do not lead to the collapse of the ideal or the failure of its pursuit, but rather to the reformulation and continuation of both.

Effects of dietary lipid source on growth, digestibility and tissue fatty acid composition of Heterobranchus longifilis fingerlings

One of the major problems facing aquaculture is the inadequate supply of fish oil mostly used for fish feed manufacturing. The continued growth in aquaculture production cannot depend on this finite feed resources, therefore, it is imperative that cheap and readily available substitutes that do not compromise fish growth and fillet quality be found. To achieve this, a 12-week feeding trial with Heterobranchus longifilis fed diets differing in lipid source was conducted. Diets were supplemented with 6% lipid as fish oil, soybean oil, palm oil, coconut oil, groundnut oil and melon seed oil. Triplicate groups of 20 H. longifilis were fed the experimental diets two times a day to apparent satiation, over 84 days. Growth, digestibility, and muscle fatty acid profile were measured to assess diet effects. At the end of the study, survival, feed intake and hepatosomatic index were similar for fish fed experimental diets. However, weight gain, SGR and FCR of fish fed soybean oil-based diet was significantly reduced. Apparent nutrient digestibility coefficients were significantly lower in fish fed soybean, coconut and groundnut oil-based diets. Fillet and hepatic fatty acid compositions differed and reflected the fatty acid compositions of the diets. Docosahexaenoic acid (22:6n-3), 20:5n-3 and 20:4n-6 were conserved in vegetable oils-based diets fed fish possibly due to synthesis of HUFA from 18:3n-3 and 18:4n-6. Palm oil diet was the least expensive, and had the best economic conversion ratio. The use of vegetable oils in the diets had positive effect on growth and fillet composition of H. longifilis.
