Objective: To determine the production cost and profitability of different feedingstrategies during the tropical gar larvicultureDesign/methodology/approach: Growth and survival obtained from the evaluationof an experimental diet with maize starch, comparing against the conventionalstrategy (commercial diet for rainbow trout and co-feeding with Artemia naupliii). Theexperimental diet was evaluated with co-feeding with Artemia and with no Artemia.The productions cost was estimated for each strategy and was calculated the unitcost by juvenile as well as the sale cost. We also determined the cost-benefit relationand the breakeven point for the economic analysis. Results: The direct feeding with no Artemia strategy during the larviculture is notprofitable. According to the relation cost-benefit, comparing the strategy with theexperimental diet in co-feeding with the conventional strategy, the profitability of thefirst was greater. The breakeven point between the profitable strategies was similar,but the greater survival with the experimental diet suggest a higher impact on theoptimization of the product system.Limitations on study/implications: the lack of economic analysis on the tropical garlarviculture affect indirectly the product system tropical gar as there is no accurate information on production costs.Findings/conclusions: From a financial point of view, the feeding strategy usingexperimental diet with co-feeding is the most profitable process of larviculture.

Financial Benefits

The present paper carries out a cost benefit analysis of centralized wastewater reuse systems in Beijing. This study consists of two parts: financial analysis and economic analysis. The financial analysis is made from the point of view of plant manager, in which financial benefits and cost is calculated. The economic analysis is made from the point of view of society, in which the economic, environmental and social benefits and cost are determined. The results of financial analysis show that the financial benefits are larger than cost, which means the centralized wastewater reuse systems are financially feasible. It implies that the investment on centralized wastewater reuse systems is profitable. The results of economic analysis show that the ratio of benefit to cost is larger than 1, which means the centralized wastewater reuse systems are economically feasible. It implies that centralized wastewater reuse systems have positive effects on the society. From the point of view of plant manager, centralized wastewater reuse systems could operate in a long term, while from the point of view of government or society, the centralized wastewater reuse systems are worth to be promoted.

These books are numbers 4 and 5, respectively, in the series "Studies in the Economic Development of India". The two books are interesting complements to one another, both being concerned with the analysis of projects within national plan formulation. However, they treat different sorts of problems and do so on very different levels. Marglin's Public Investment Criteria is a short treatise on the problems of cost-benefit analysis in an Indian type economy, i.e., a mixed economy in which the government accepts a large planning responsibility. The book, which is wholely theoretical, explains the many criteria needed for evaluation of projects. The work is aimed at beginning students and government officials with some training in economics. It is a clear and interesting "introduction to the special branch of economics that concerns itself with systematic analysis of investment alternatives from the point of view of a government".

Currently, the pork industry is incorporating in-line automation with the aim of increasing the slaughtered pork carcass throughput while monitoring quality and safety. In Korea, 21 parameters (such as back-fat thickness and carcass weight) are used for quality grading of pork carcasses. Recently, the VCS2000 system—an automatic meat yield grading machine system—was introduced to enhance grading efficiency and therefore increase pork carcass production. The VCS2000 system is able to predict pork carcass yield based on image analysis. This study also conducted an economic analysis of the system using a cost—benefit analysis. The subsection items of the cost-benefit analysis considered were net present value (NPV), internal rate of return (IRR), and benefit/cost ratio (BC ratio), and each method was verified through sensitivity analysis. For our analysis, the benefits were grouped into three categories: the benefits of reducing labor costs, the benefits of improving meat yield production, and the benefits of reducing pig feed consumption through optimization. The cost-benefit analysis of the system resulted in an NPV of approximately 615.6 million Korean won, an IRR of 13.52%, and a B/C ratio of 1.65.

Disease Epidemics

The total number of infections (epidemic size), and the time needed for the infection to die out (epidemic duration), represent two of the main indicators for the measuring gravity of infectious disease epidemics in humans. A few attempts have been made to address the problem of controlling both the epidemic size and duration simultaneously from a theoretical point of view, by primarily using the Optimal control theory. In this study, a multi-objective optimal control problem has been simulated to gauge the success of the lockdowns in India. To accomplish this objective, a system dynamics modeling was used to simulate the Susceptible–Infected–Quarantined–Removed epidemic model. A set of sensitivity experiments for different scenarios allows illustrating the model’s behavior and its value for decision-makers regarding the lockdown intensity. The simulation of the model presents various scenarios, wherein the cost–benefit analysis of lockdown was done. Notably, the lockdown success intensity was defined, post which, the findings indicate that the states of Uttar Pradesh, Kerala, Panjab, Jammu, Kashmir, Haryana, and Bihar have achieved more than 90% lockdown success intensity. Further, it was observed that these states could effectively implement lockdowns by strictly enforcing social distancing measures during the early stages of the virus spread, which in turn resulted in the high success rate of lockdowns.

In the present-day society, people spend about 80% of their time inside buildings, and specifically 30-40% in workplaces. From this evidence, the indoor environmental quality needs to be investigated, and in particular, the possible sources of indoor-outdoor pollutants and their impact on the human health, comfort and productivity. First, through an examination of the indoor sources of pollution, the research analysed the main substances that affect indoor air quality in an office. Second, the pollution of external origin and its effects on the performance of employees were taken into consideration. Two scenarios were designed for a Heating Ventilation Air Conditioning (HVAC) system in an office building; one by the installation of a biocidal filter and the other by a traditional one. Two methods were applied to evaluate and compare those scenarios; the Cost Benefit Analysis and the Monte Carlo Simulation. From a financial point of view, the investment and management costs of the filters were considered. Instead, the annual benefits included increasing productivity and reducing days of absence from work due to illness. The results confirmed the energy and socio-economic efficiency of the antibacterial filter; it can be considered a solution to achieve the best income.

Tetanus Vaccination

SUMMARYA mathematical model has been developed which allows estimation of the epidemiological and economic effects of different tetanus vaccination strategies. The model was used to simulate the epidemiology of tetanus in italy from 1955 to 1982, and then applied to a district of Tuscany by utilizing data obtained from a seroepidemiological survey carried out in the same area. For this district we simulated vaccination programmes designed to reach, within 1 or 10 years, coverages of 60 or 90% of the population aged over 10 years who had not been exposed to the neonatal vaccination programme. The most effective strategy, from both the epidemiological and economic point of view, seems to be 90% coverage reached in 1 year's time. Benefits would be increased by improving the reliability of vaccinal anamnesis.

This paper examines the application of the techniques of economic analysis to occupational health and safety regulations using occupational noise as an example. The paper explores the extent to which economic impact studies are practically feasible and useful in relation to occupational health and safety legislation. Six studies of the same regulatory change, from four countries were analysed. The results of these studies ranged from a strongly negative to a significantly positive net present value, depending on the assumptions made. The factor which had the greatest influence on these differences was the way in which benefits are costed. It is shown that in the field of Occupational Health and Safety, economic analysis does not produce a single valid net present value or benefit to cost ratio on which a decision to legislate can sensibly be based. However the analysis can, if properly directed provide useful information on factors which will enable organisations to optimise their response to the regulation and authorities to introduce regulations in a way which does not bear with unreasonable weight on specific sectors of the community.

The techniques of cost/benefit analysis are presented in a general way in order to encourage decision-makers in the crim inal justice system to adopt a style of thought that will assist them in formulating decisional alternatives. Discussion of the promises and pitfalls of the technique addresses the question of whether the "benefits" of cost/benefit analysis are sufficient to outweigh the "costs" in its adoption. The authors contend that the technique can be quite useful to executives in their quest to manage their organizations toward the achievement of organizational goals because the technique will enable them to identify new programs worthy of experimentation, will encour age the development of an accurate information system, will en hance their ability to base programatic decisions on community and social indicatcrs, and will better equip them in their rela tionships with legislators, funding bodies, and interest groups.

Abstract The paper presents possibilities of an economic evaluation of hard coal mines, using Cost Benefit Analysis (CBA). Suggested methodology for CBA applied to the economic evaluation of a mine allows to conduct a complex evaluation of mine’s functionality in connection to Polish conditions. Additionally to financial aspects, significant from the point of view of the mine’s owner, the paper includes social and environmental effects as a result of mining activities. Proposed methodology has undergone tests which used averaged data obtained from two selected hard coal mines located in the Upper Silesian Coal Basin. Presented results confirm the validity of social costs and benefits, and environmental losses resulting from mining operation, which were included in analysis comprehensively evaluating the efficiency of hard coal mines.
