  Citation × Citation Citation Abstract Copy Title: Performance of three inbred lines of Herford cattle and their linecrosses Author: Munji, Marcus Tebid Three inbred and relatively unrelated lines of Hereford cattle (1. Lionheart, 2. Prince, and 3. David) developed at the Corvallis branch of the Oregon Agricultural Experiment Station as part of the W-1 project of the Western States were crossed annually from 1963 through 1965 inclusive. Data on 137 inbred and linecross calves born during the three-year period were analysed for four production traits: birth weights, suckling rates of gain, average daily gains and feed efficiency (pounds of feed per 100 pounds of gain). There were 79 male and 58 female calves. Twenty-three of the male calves were inbred while 56 were linecross calves. There were 16 inbred and 42 linecross female calves. The purpose of the study was to compare the mean performance of any two inbred lines used to make crosses with the mean performance of their reciprocal linecrosses for possible heterotic effects. All possible diallelic crosses were made among the three lines in each year and all calves were weaned and feed-tested on a constant-weight basis. Male calves were feed-tested from 450 to 800 pounds and again between 800 and 1000 pounds while female calves were feed-tested from 400 to 750 pounds. They were fed all they could eat for three hours each morning and three hours each evening. The ration and other management details are described. Selection was on an index basis with automatic culling for inherited defects and abnormalities. Results were reported separately for bull and heifer calves. Comparisons were mostly on a within-sex basis and always on a within-line basis. For both male and female calves, there was no significant difference between the mean birth weights and mean suckling rates of gain of inbred calves and their reciprocal linecross relatives. There was a non-significant difference between male, and female inbred and linecross calves. There was more variability among female than among male calves in suckling gains. On the average, linecross calves of both sexes at younger ages within lines gained more rapidly and were more efficient than inbred calves, with the exception of the 2 x 3 + 3 x 2 linecross male calves which gained slightly less than their inbred relatives between 450 and 800 pounds body weight. The 1 x 2 + 2 x 1 linecross heifers were significantly superior (P < 0.01) by 0.28 pounds per day and showed a saving of about 113 pounds of feed per 100 pounds of gain over their inbred relatives. All linecross calves were non-significantly more efficient in feed utilization than their within-line inbred relatives and there were indications of more heterosis in female than male linecrosses. However, in the 800 to 1000 pound feed test period in the males, the mean daily gain and mean feed efficiency of each pair of inbred lines exceeded those of the respective reciprocal linecrosses. This reversal of growth rate and economy of gains between linecross and inbred calves within the 800 to 1000 pound feed-test period seems to indicate that inbred calves of the same chronological age with linecross calves are physiologically younger and consequently less rapid and less efficient in rate and economy of gains at earlier ages. The implication here is that inbreeding depresses early production traits more than it does later-life traits. Because of the low heterotic effects obtained in this study, the suggestion is being made that, in future crosses of these inbred lines, linecross calves from linecross dams be compared with inbred calves from inbred dams since it is known that inbreeding of both dam and calf affect the performance of the calf.

  Citation × Citation Citation Abstract Copy Title: Serving Amid Institutional Camouflage : The Invisibility of School Food Service Workers Author: Byrd, Janette The products, processes, and tools of school feeding programs have been examined from multiple perspectives and disciplines in an attempt to improve child nutrition outcomes, to support local and national agriculture, and increase sustainability practices. There is little qualitative research on the role, needs, and experiences of school food service workers, and what is available tends to focus on how workers can be used to improve student’s nutritional profiles rather than the workers own experiences and needs as members of the labor economy. Unlike other studies on school feeding programs that are food-centric and mostly quantitative, this fills a gap in the literature as a qualitative, worker-centric study. Ten school food service workers in a suburban northwest Oregon school district where interviewed, and participant observation through volunteer work took place in one elementary school, one middle school and one high school. Combined with a historical account school food service, and a review of current studies, the data shows that school food service workers are invisible, and excluded from full participation in the programs they deliver. One way to increase worker visibility and seek advocacy opportunities is to trace the workers’ historical and current associations, and the corresponding narratives born of the controversies and contradictions of neoliberalism. Tracing associations led to the following researcher recommendations: 1) Workers need access to living wages, and affordable health care; 2) Need national demographic data to justify wages, hours, and benefits; 3) Need worker-centric research to balance the food-centric literature; 4) School Food Service Workers need a dedication National Union; 5) Labor unions should use this data to increase worker visibility; 6) Educational unions should assist workers in advocating for a USDA certification program; 7) Training for certification must go beyond culinary training to include nutrition training, farm-to-school program development, school-garden development, and nutrition and sustainability education training, and summer meal programs; and 8) National service programs should be administered directly through the schools rather than non-profit programs and be used as a jobs strategy to fill gaps in employment Title: Serving Amid Institutional Camouflage : The Invisibility of School Food Service Workers Author: Byrd, Janette The products, processes, and tools of school feeding programs have been examined from multiple perspectives and disciplines in an attempt to improve child nutrition outcomes, to support local and national agriculture, and increase sustainability practices.

  Citation × Citation Citation Abstract Copy Title: Pegged currency and trade performance : a case study of Cameroon's cotton exports Author: Tindjou N., Robert B Since its creation in 1948, the African Franc Zone currency (the CFA franc) was pegged to the French franc at an unchanged fifty to one parity. This study examines the trade effect of this fixed exchange rate on the Franc Zone's member countries. Cameroon cotton exports is considered on a case study approach. Two non-Franc Zone countries, Turkey and Tanzania are included in the analysis for comparison purpose. An econometric model for cotton exports was estimated for each of the three countries using the Seemingly Unrelated Regression (SUR) Method. The fluctuations of the CFA franc are not shown to have stimulated or impeded Cameroon's cotton exports in a systematic way which can be captured in the present quantitative analysis. Thus the research supports neither the position that the pegged currency helps exports performance nor the position that it causes harm. Contrary to theoretical expectation, Cameroon's cotton export is shown to be negatively related (and significantly so) to the world prices, suggesting that Cameroon's cotton trade is not consistent with the assumed revenue maximizing behavior. In strong contrast to Cameroon's results, but in agreement with theoretical expectation, the evidence for Turkey and Tanzania suggest that their cotton exports were affected by their real exchange rates and the world prices. One possible explanation for the apparent neutrality of the exchange rate for Cameroon is the prominent (but declining since 1985) role that France played as an importer of the Cameroonian cotton. Over the sixteen years study period. Linking of the economies through such trading relationship is one of the expected outcome of the monetary alignment. Discussion regarding the desirability of such a strong linkage to France's econony may be fruitful, particularly given the changes taking place in Europe.

Meanwhile it is considered as activities which specify general development strategies of a nation, sector or even a specific field; it also is the basis for developing and implementing development projects (Huong, 2005). Therefore, it is essential to recognize the challenges, opportunities and solutions in enhancing the planning capacity. Vietnamese Fisheries managers and other stakeholders have been facing a number of challenges. Being an efficient fishery planner requires a broad-spectrum knowledge and skills which have been changing and updating quickly in the modern dynamic world. The second issue is why and how to corporate in planning process. Other challenge is how to solve various conflicts (related to economics, social and environment value). Financial and other regulations are also major issues impacting on the quality of planning. Opportunities of innovations for planners, however, have been being more available and they need to be recognized and applied effectively. These opportunities occur since there has been development in Economy, Education, Technology, and the chances of joining the global market. To enhance the capacity of fisheries planning, a package of effective solutions should be considered. They mainly are of upgrading the regulation and awareness (related to supply of data, updating knowledge, evaluation and monitoring of planning process&); considering in more suitable way to organize, to develop and implement planning process.
