Application of ipil- ipil leaf meal (IILM) as feed Ingredient for Monosex tilapia fry (oreochronis niioticus) : In terms of growth and economics

The Ipil-ipil (Leucaena leucocephal) leaf analyzed for crude protein (CP), fat, crude fibre (CF), ash content, moisture content and nitrogen free extract (NFE). The CP 23± 0.12 % , fat 8 ± 0.11 %, CF 18 ± 0.15 % , ash 10 ± 0.13 %, moisture 14. ± .16% and NFE 29.± 1.10 % were recorded. A twenty one days experiment was conduced to assess the response of juvenile monosex tilapia with different iso-nitrogenous formulated diets for find out the feasibility study of using ipil-ipil leaf meals as feed ingredient for juvenile tilapia. Three experimental diets were formulated by using fish meal, soybean meal, rice bran and ipil ipil leaf meal. One control diet was formulated by using fish meal, soybean meal and rice bran. Considering the high demand, limited availability of fish meal and soybean meal, ipil ipil leaf meal was incorporated in juvenile tilapia feed. Among plant protein ingredients ipil ipil leaf meal was considered as the most nutritive plant protein source after soybean meal. However, high concentration of toxic element limited the incorporation level of ipil ipil leaf meal in fish feed. Use of 15 % ipil ipil leaf meal in fish feed was more significant from the view of growth performance and economics. The higher Absolute Growth was 1119.26 gm, higher Specific Growth Rate was 6.52% /day higher Feed Conversion Efficiency was 41.23% , higher Protein Efficiency Ratio was 1.178 and higher Average Daily Growth rate was 14.00% recorded in diet-4 ( which contained 15% IILM). The lower Feed Conversion Ratio 2.42 and lower cost for per unit production 34.65 taka/kg were recorded in diet-4. The higher cost for per unit fish production 45.6 tk./kg was recorded for diet-1 where no ipil ipil leaf meal.. The results suggest that tree legumes Ipil-ipil (Leucaena leucocephal) leaf has potential and excellent source of feed ingredients as protein supplements for juvenile monosex

Three essays on economics and information shocks

A person living in an industrialized society has almost no choice but to receive information daily with negative implications for himself or others. His attention will often be drawn to the ups and downs of economic indicators or the alleged misdeeds of leaders and organizations. Reacting to new information is central to economics, but economics typically ignores the affective aspect of the response, for example, of stress or anger. These essays present the results of considering how the affective aspect of the response can influence economic outcomes.

The first chapter presents an experiment in which individuals were presented with information about various non-profit organizations and allowed to take actions that rewarded or punished those organizations. When social interaction was introduced into this environment an asymmetry between rewarding and punishing appeared. The net effects of punishment became greater and more variable, whereas the effects of reward were unchanged. The individuals were more strongly influenced by negative social information and used that information to target unpopular organizations. These behaviors contributed to an increase in inequality among the outcomes of the organizations.

The second and third chapters present empirical studies of reactions to negative information about local economic conditions. Economic factors are among the most prevalent stressors, and stress is known to have numerous negative effects on health. These chapters document localized, transient effects of the announcement of information about large-scale job losses. News of mass layoffs and shut downs of large military bases are found to decrease birth weights and gestational ages among babies born in the affected regions. The effect magnitudes are close to those estimated in similar studies of disasters.

Essays in revealed preference theory and behavioral economics

Time, risk, and attention are all integral to economic decision making. The aim of this work is to understand those key components of decision making using a variety of approaches: providing axiomatic characterizations to investigate time discounting, generating measures of visual attention to infer consumers' intentions, and examining data from unique field settings.

Chapter 2, co-authored with Federico Echenique and Kota Saito, presents the first revealed-preference characterizations of exponentially-discounted utility model and its generalizations. My characterizations provide non-parametric revealed-preference tests. I apply the tests to data from a recent experiment, and find that the axiomatization delivers new insights on a dataset that had been analyzed by traditional parametric methods.

Chapter 3, co-authored with Min Jeong Kang and Colin Camerer, investigates whether "pre-choice" measures of visual attention improve in prediction of consumers' purchase intentions. We measure participants' visual attention using eyetracking or mousetracking while they make hypothetical as well as real purchase decisions. I find that different patterns of visual attention are associated with hypothetical and real decisions. I then demonstrate that including information on visual attention improves prediction of purchase decisions when attention is measured with mousetracking.

Chapter 4 investigates individuals' attitudes towards risk in a high-stakes environment using data from a TV game show, Jeopardy!. I first quantify players' subjective beliefs about answering questions correctly. Using those beliefs in estimation, I find that the representative player is risk averse. I then find that trailing players tend to wager more than "folk" strategies that are known among the community of contestants and fans, and this tendency is related to their confidence. I also find gender differences: male players take more risk than female players, and even more so when they are competing against two other male players.

Chapter 5, co-authored with Colin Camerer, investigates the dynamics of the favorite-longshot bias (FLB) using data on horse race betting from an online exchange that allows bettors to trade "in-play." I find that probabilistic forecasts implied by market prices before start of the races are well-calibrated, but the degree of FLB increases significantly as the events approach toward the end.

Estratégias corporativas da indústria de frangos: Um estudo exploratório

A indústria de frangos brasileira, representa um importante gerador de divisas e empregos, e tem-se destacado no cenário internacional altamente competitivo, e com fortes barreiras de entrada, sejam elas de natureza econômica, sanitárias, ou econômicas disfarçadas por uma justificativa sanitária. O excelente desempenho do setor, justifica-se pelos diversos fatores, sejam eles de natureza econômica, geográfica, e pela competência das principais empresas do setor. Neste sentido, é que o presente estudo teve como objetivo analisar as principais estratégias adotadas pelas duas maiores empresas brasileiras exportadoras de carne de frango, líderes no setor. Após análise de diversos relatórios setoriais, materiais institucionais das próprias empresas, e consultas à diversos artigos sobre o setor, realizou-se um breve questionário com o objetivo de identificar as principais estratégias destas empresas, além de possíveis ferramentas de análise estratégica utilizadas. Verificou-se que as estratégias gerais das empresas baseiam-se na diversificação de produtos para atender a novos mercados. Para isso torna-se necessário o investimento em inovação, como objetivo de desenvolvimento de produtos de maior valor agregado. Além disso somente uma das empresas analisadas utiliza-se de ferramentas formais de análise estratégica, mais conhecidas pela literatura acadêmica.

Fish quality and processing in Malawi: responding to challenges through institutional capacity building

Fish processing and quality control in Malawi are still poorly developed. Traditional fish processing methods are widely employed resulting in considerable post-harvest losses. One of the major challenges to steady and sustainable development in fish processing and quality management is the lack of adequately trained personel. This is directly reflected in poor institutional capacity. This project analyses the situation in fish processing and quality management in Malawi to identify gaps that require improvement. Specifically, the project assesses the role of training institutions in Malawi in capacity building for fish processing and quality management. The institution under discussion in this project is the Aquaculture and Fisheries Science Department at Bunda College of Agriculture, Malawi which is responsible for training students in aquaculture and fisheries science at the undergraduate level.Improvement in the teaching of fish processing and quality management in the Department of Aquaculture and Fisheries Science was identified as the major gap requiring action. The current teaching syllabus was thus analysed to identify weak areas. In conclusion, the project developed (as the major output) a teaching handbook for the Department of Aquaculture and Fisheries Science.
