This type of fishing does not yet meet the local population’s demand for fish products. In response to this concern, a Community Agricultural Estate housing an integrated fish farm was set up in the commune of Bandafassi, in the village of Itato. Since its creation, this production unit has been faced with the problem of sourcing high-quality, low-cost, monosex male Oreochromis niloticus fry. In order to overcome this constraint, the present research focuses on the contribution of Garcinia kola to the productivity and economic profitability of the Itato farm. The aim of the research is to assess fish production in the experimental set-up and the production costs of tilapia in a controlled environment. The comparative study of the various production factors shows disparities only in the input factor, where scenarios 2 and 3 use additional products. These are 17-α-methytestosterone for scenario 2 and Garcinia kola for scenario 3. These products significantly interfere with fish production, with a fairly high mortality rate for scenario 2 (25% for two production cycles/ cohort2 (B5, B6, B7 and B8) treated with 17-α-methytestosterone). As for scenarios 1 and 3, mortalities are 5% with or without recourse to additional products (G. kola). In addition, average fish production for the three (03) scenarios is estimated at 28687.5 kg/2 cycles. It varies from one scenario to another, i.e. 30937.5 kg/2 cycles for scenarios 1 and 3 and 24187.5 kg/2 cycles for scenario 2. It is therefore higher in scenarios 1 and 3 than in scenario 2. This difference is due to the fairly large losses of individuals in scenario 2. Furthermore, the analysis of the profit and loss accounts for tilapia production varies from one scenario to another depending on the type of farm: 476 Franc CFA for scenario 1, 610 Franc CFA for scenario 2 and 472 Franc CFA for scenario 3 (F CFA = franc of the French Colonies of Africa). The Average operating income for all the fish farming units is 34,726,142 Franc CFA. The highest (41,638,075 Franc CFA) and lowest (29,281,075 Franc CFA) ERs were observed in scenarios 3 and 2 respectively. It was 33,259,275 Franc CFA for scenario 1. The difference between the NERs of the three scenarios is more or less significant in terms of results. The operating result (OR) is positive in all 3 scenarios in our study. However, the scenario 3 system generates a higher rate of return (the ratio between an income and the capital employed to obtain that income) (74%) than that generated by the scenario 1 system (69%). As for the scenario 2 system, it generates a lower financial return than the two previous systems (67%). Above all, this work made it possible to construct an approach that would make it possible to answer such a question by relying successively on various methods: a typology, according to the production factors involved in the operation of the Community Agricultural Estate fish farm.展开更多

It has been recommended by the WHO since 2013 for children from the age of 3-59 months. However, despite the impact of this intervention, a peak in the prevalence and incidence of malaria is observed in children from the age of 5-9 years. The aim of this study is to determine from the current literature the feasibility, impact and cost-effectiveness of extending SMC to five cycles and to older children. Methods: A litterature search of PubMed/Medline, NCBI and Google scholar identified 1333 articles. After reading the titles and abstracts by two authors, 24 articles were selected and submitted for full reading. Random control studies on the extension of SMC, malaria, feasibility of SMC, impact of SMC and cost-effectiveness of SMC were selected. A total of 16 articles were included for the qualitative synthesis after excluding 8 studies. Results: Following the summary of the evidence, we conclude that the extension is feasible but will be confronted with the unavailability of older children. The intervention period coincides with field work. SMC is effective in reducing the prevalence and incidence of malaria and the parasite density in children. The financial cost of administering SMC is lower than that of treating a child suffering from malaria. Conclusion: After analysing the information, it was found that the majority of the African population supports the extension of the SMC to the number of cycles and the age group in order to alleviate the high mortality and morbidity rates among children due to malaria.展开更多

For a salable product, supply chain mode of VMI is established, which is based on deterministic demand, having initial stock and having stock-out cost. With the further analysis of the mode, VMI is found to increase profits of the buyer in the short-term motivation. But VMI will reduce profits of the supplier under the matching condition. And in the short-term motivation, VMI will increase the purchase price to compensate the transfer cost of the supplier. As a result, the foundation of theory is provided to implement VMI in the supply chain, and have some definituded project significance.展开更多

With the support of policies, long-term lease apartments have begun to emerge. However, under the multi-subject supply, longterm lease apartments have encountered problems such as small profits in their development. Starting from the background of the development of long-term lease apartments, this study classified the main types of long-term lease apartments, analyzed the four profit models of comprehensive profit, expansion of rent difference, REITs and value-added services based on their business models, and proposed corresponding suggestions on the profitability of long-term lease apartments according to the current situation of profit difficulty of long-term lease apartments and the lack of profit models.展开更多

In this study, the total production volume of the theoretical plant was 200,000 tons per year and the raw wood materials used were birch pulpwood, spruce pulpwood, pine pulpwood, and energy wood. These wood materials were young delimbed wood from early thinnings. The main goal of the paper was to illustrate that the energy content differences of raw wood materials affect the economic profitability of a bio-coal pellet plant at regional level. In this case, wood type also has a regional economic impact, which the pellet plant can influence through its raw wood material choices. The raw material comparison was based on measured data and not computational or literary data alone. The study found that lower solid wood energy densities caused higher relative costs for the total supply chain. A parallel phenomenon occurred with the required gross margin of the pellets, where lower energy content caused higher required gross margin for pellet sales. The gross margin was also sensitivity analyzed at different discount rates from 5% to 20%. At each required discount rate, the highest annual economic impact on the region was found for birch pellets, with values of 36.95 - 42.66 million €. Spruce pellets had the smallest annual economic impact, although it had the highest final pellet price in the same cases. The different economic effects were caused by the energy volumes sold.展开更多

From an overall social perspective, such high profitability means an inefficient allocation of industrial resources and a potential loss of social welfare. Therefore, further expanding and deepening the reform of SOE property rights, encouraging the development of non-SOEs and boosting the competitiveness of basic industries will significantly improve the resource allocation efficiency of the Chinese industry and enhance overall social welfare.展开更多

From the perspective of the Cloud Service Providers (CSPs), this is not beneficial as they may lose the opportunity to earn from the relinquished resources. Therefore, this paper tackles the resource assignment problem while considering users relinquishment and its impact on the net profit of CSPs. As a solution, we first compare different ways to predict user behavior (i.e. how likely a user will leave the system before its scheduled end time) and deduce a better prediction technique based on linear regression. Then, based on the RACE (Relinquishment-Aware Cloud Economics) model proposed in [1], we develop a relinquishment-aware resource optimization model to estimate the amount of resources to assign on the basis of predicted user behavior. Simulations performed with CloudSim show that cloud service providers can gain more by estimating the amount of resources using better prediction techniques rather than blindly assigning resources to users. They also show that the proposed prediction-based resource assignment scheme typically generates more profit for a lower or similar utilization.展开更多

This research looked at the elements that influence airline profitability in Nigeria. From 2005 to 2019, two airlines were picked, and their data were retrieved from Nigerian Civil Aviation Authority (NCAA). From estimated quarterly panel data using E-views 8 and SPSS 22, the overall findings of the regression study demonstrate that with ROA used as a proxy for profitability, the R-square is 83.6 per cent and 89.4 per cent, respectively for Aero contractors and Medview airline, representing 83.6 per cent and 89.4 per cent of the changes in profitability of the Aero contractors and Medview in the sample, respectively, could be explained by changes in the study’s independent variables, namely growth, liquidity, leverage, lease, tangibility, fuel cost and personnel cost. Besides the total of the explanatory variables, growth, leverage and tangibility are statically significant at a 5% level of significant Aero Contractors. Growth, leverage, leasing cost, fuel cost, and staff cost, on the other hand, are statistically significant at the 5% level of significance for Medview airlines. Profiteering, expansion, leverage, and tangibility are the primary activities of any airline firm. Lease cost, fuel cost, and staff cost show a statistically significant positive link with the profitability metric ROA. As a result, stakeholders of Nigerian airlines should prioritize profitability over other criteria in this study. Airline executives should do a comprehensive analysis of all potential elements impacting their company’s profitability in the literature, including aspects other than economic variables. According to the findings of this study, political issues account for a greater proportion of the reasons why airlines fail in Nigeria.展开更多

This need was the main reason the author has designed the model named "Insured Education System Model---IESM". The IESM is based on the principle that expenditures incurred at each stage of educational attainment should not be burdened upon the person himself/herself. There should be insurance companies willing to cover the educational expenditures of the buyers. The suggested IESM model also creates an auto-control mechanism within the financing system through which insurance companies, educational institutions (buyers), and households will gain benefits. Furthermore, the IESM will increase the quality of service within the overall educational system, and create employment, as well as eliminating the number of school drop outs. The system will bring a significant decrease in the cost of the service. This study presents the results of the analyses on the data collected by the author on the perception of the proposed Insured Education System Models through surveys conducted in selected schools in Istanbul. The survey is unique in a sense that for the first time in literature such a model is suggested and the perception of relevant stake holders are tested through a questionnaire of 42 questions. The results show that there is an approval rate of more than 50% regarding to the IESM. And the frequency analysis suggests that the IESM is an applicable model.展开更多

However, the assessment of the energy profitability of a technology is still a controversial topic, especially when renewable-based systems are compared with non-renewable ones and when the depletion of the stocks of available resources is not accounted properly. As a matter of fact, some popular energy indicators do not seem to cover all the aspects of the problem, with the risk of drawing ambiguous conclusions. A set of life cycle-based indicators is proposed in order to establish a more reliable approach to the assessment of energy products which decouples the different contributions given by renewable and non-renewable resources. The proposed set of indicators has been quantified for different groups of energy products and compared with an energy indicator frequently used (i.e. EROI). A coherent assessment of the depletion of energy resources and of the energy profitability of the products is presented. The indicators could even contribute to understand the feasibility of energy projects and plans by evaluating their impact on the stock of energy resources.展开更多

文摘The optimization policy of the purchase price and the profit under vendor managed inventory(VMI) is studied. For a salable product, supply chain mode of VMI is established, which is based on deterministic demand, having initial stock and having stock-out cost. With the further analysis of the mode, VMI is found to increase profits of the buyer in the short-term motivation. But VMI will reduce profits of the supplier under the matching condition. And in the short-term motivation, VMI will increase the purchase price to compensate the transfer cost of the supplier. As a result, the foundation of theory is provided to implement VMI in the supply chain, and have some definituded project significance.
文摘Traditional profit allocation solutions cannot be effectively applied to the practice for the limitations in their premises and principles. This paper based on the practical processes of virtual supply chain performs analysis on major factors relative to cost and risk which effect the profit allocation among the partners, and then proposes the quantitative relations between the factors and profit allocation. The relations can serve as a base for further research on extensive profit allocation model.
文摘This paper uses generalized method of moments(GMM),Least Squares(LS)and Generalized Linear Model(GLM)to examine the impact of competition on profitability of banks and Stochastic Frontier approach(SFA)is used to estimate of cost efficiency.We have used an unbalanced panel dataset from a sample of emerging economic MENA countries over the period between 2011 and 2017.We find out that have a significant and negative impact of competition on profitability of banks.The empirical findings of this study suggest that(1)MENA banks should more improve the process of managing and monitoring the loan segment business;the result which reducing in the level of credit risk which leads to higher profitability(2)MENA banks should shrink higher level of banking sector development.(3)MENA banks should make full conduct of available funds to engage in various natures of businesses;if there is an issue of insolvency,robust government support would give protection to MENA banks.Finally,it also provides some compulsory policy implications which will be very much beneficial for a wide range of stakeholders.
文摘The acceleration of urbanization has led to an increase in the number of urban floating population, which leads to more demands for the housing rental market. With the support of policies, long-term lease apartments have begun to emerge. However, under the multi-subject supply, longterm lease apartments have encountered problems such as small profits in their development. Starting from the background of the development of long-term lease apartments, this study classified the main types of long-term lease apartments, analyzed the four profit models of comprehensive profit, expansion of rent difference, REITs and value-added services based on their business models, and proposed corresponding suggestions on the profitability of long-term lease apartments according to the current situation of profit difficulty of long-term lease apartments and the lack of profit models.

文摘The aim of this paper was to compare the annual economic impact of a large-scale bio-coal pellet plant by raw material specifically for the Finnish Lakeland region. In this study, the total production volume of the theoretical plant was 200,000 tons per year and the raw wood materials used were birch pulpwood, spruce pulpwood, pine pulpwood, and energy wood. These wood materials were young delimbed wood from early thinnings. The main goal of the paper was to illustrate that the energy content differences of raw wood materials affect the economic profitability of a bio-coal pellet plant at regional level. In this case, wood type also has a regional economic impact, which the pellet plant can influence through its raw wood material choices. The raw material comparison was based on measured data and not computational or literary data alone. The study found that lower solid wood energy densities caused higher relative costs for the total supply chain. A parallel phenomenon occurred with the required gross margin of the pellets, where lower energy content caused higher required gross margin for pellet sales. The gross margin was also sensitivity analyzed at different discount rates from 5% to 20%. At each required discount rate, the highest annual economic impact on the region was found for birch pellets, with values of 36.95 - 42.66 million €. Spruce pellets had the smallest annual economic impact, although it had the highest final pellet price in the same cases. The different economic effects were caused by the energy volumes sold.
文摘An analysis of the sources of profit growth for China's state-owned industry since 1999 indicates that the key source of profit growth is not the high productivity of state-owned enterprises (SOEs) but rather their monopoly position and pricing power in some basic industries. From an overall social perspective, such high profitability means an inefficient allocation of industrial resources and a potential loss of social welfare. Therefore, further expanding and deepening the reform of SOE property rights, encouraging the development of non-SOEs and boosting the competitiveness of basic industries will significantly improve the resource allocation efficiency of the Chinese industry and enhance overall social welfare.

文摘Through analyzing the economic profits of rural cooperative economic organizations,the following conclusions are obtained.The rural cooperative economic organizations can get the economic profits which are in accordance with the demands of market-oriented economy.The rural cooperative economic organizations can benefit from sharing the knight service provided by the government;from reducing and avoiding various kinds of risks in operation and from applying the agricultural technology and standardization production.Besides,the organizations can share the profits bought along by the standardized production of agricultural production and their members can enjoy the profits bought by socialized service system.In addition,the rural cooperative economic organizations can enjoy the profits produced by the agricultural management integration strategy.What' more,they can increase profits by reducing the transaction costs;enlarging scale and enjoying the brand advantages.The analyses of the costs of the development of rural cooperative economic organizations mainly include the organizing costs,operation costs,restriction costs and cooperation costs.We think that the slow development of rural cooperative economic organizations is caused by their high operation cost and the impediment of external environment.In the end,the countermeasures on strengthening the research on the theory,promotion,education and training of rural economic cooperative organizations and intensifying the supports on the policies of rural economic cooperative organizations are put forward.
文摘In a cloud computing environment, users using the pay-as-you-go billing model can relinquish their services at any point in time and pay accordingly. From the perspective of the Cloud Service Providers (CSPs), this is not beneficial as they may lose the opportunity to earn from the relinquished resources. Therefore, this paper tackles the resource assignment problem while considering users relinquishment and its impact on the net profit of CSPs. As a solution, we first compare different ways to predict user behavior (i.e. how likely a user will leave the system before its scheduled end time) and deduce a better prediction technique based on linear regression. Then, based on the RACE (Relinquishment-Aware Cloud Economics) model proposed in [1], we develop a relinquishment-aware resource optimization model to estimate the amount of resources to assign on the basis of predicted user behavior. Simulations performed with CloudSim show that cloud service providers can gain more by estimating the amount of resources using better prediction techniques rather than blindly assigning resources to users. They also show that the proposed prediction-based resource assignment scheme typically generates more profit for a lower or similar utilization.

文摘A firm’s profitability is critical to its competitiveness and sustainability. This research looked at the elements that influence airline profitability in Nigeria. From 2005 to 2019, two airlines were picked, and their data were retrieved from Nigerian Civil Aviation Authority (NCAA). From estimated quarterly panel data using E-views 8 and SPSS 22, the overall findings of the regression study demonstrate that with ROA used as a proxy for profitability, the R-square is 83.6 per cent and 89.4 per cent, respectively for Aero contractors and Medview airline, representing 83.6 per cent and 89.4 per cent of the changes in profitability of the Aero contractors and Medview in the sample, respectively, could be explained by changes in the study’s independent variables, namely growth, liquidity, leverage, lease, tangibility, fuel cost and personnel cost. Besides the total of the explanatory variables, growth, leverage and tangibility are statically significant at a 5% level of significant Aero Contractors. Growth, leverage, leasing cost, fuel cost, and staff cost, on the other hand, are statistically significant at the 5% level of significance for Medview airlines. Profiteering, expansion, leverage, and tangibility are the primary activities of any airline firm. Lease cost, fuel cost, and staff cost show a statistically significant positive link with the profitability metric ROA. As a result, stakeholders of Nigerian airlines should prioritize profitability over other criteria in this study. Airline executives should do a comprehensive analysis of all potential elements impacting their company’s profitability in the literature, including aspects other than economic variables. According to the findings of this study, political issues account for a greater proportion of the reasons why airlines fail in Nigeria.
文摘In the field of education, there is a need for a financing system which is affordable, yet effective, as well as profitable, and is based on user participation. This need was the main reason the author has designed the model named "Insured Education System Model---IESM". The IESM is based on the principle that expenditures incurred at each stage of educational attainment should not be burdened upon the person himself/herself. There should be insurance companies willing to cover the educational expenditures of the buyers. The suggested IESM model also creates an auto-control mechanism within the financing system through which insurance companies, educational institutions (buyers), and households will gain benefits. Furthermore, the IESM will increase the quality of service within the overall educational system, and create employment, as well as eliminating the number of school drop outs. The system will bring a significant decrease in the cost of the service. This study presents the results of the analyses on the data collected by the author on the perception of the proposed Insured Education System Models through surveys conducted in selected schools in Istanbul. The survey is unique in a sense that for the first time in literature such a model is suggested and the perception of relevant stake holders are tested through a questionnaire of 42 questions. The results show that there is an approval rate of more than 50% regarding to the IESM. And the frequency analysis suggests that the IESM is an applicable model.
文摘The concern on climate change and on the limitations of fossil fuels is leading to the promotion of renewable-based energy options. However, the assessment of the energy profitability of a technology is still a controversial topic, especially when renewable-based systems are compared with non-renewable ones and when the depletion of the stocks of available resources is not accounted properly. As a matter of fact, some popular energy indicators do not seem to cover all the aspects of the problem, with the risk of drawing ambiguous conclusions. A set of life cycle-based indicators is proposed in order to establish a more reliable approach to the assessment of energy products which decouples the different contributions given by renewable and non-renewable resources. The proposed set of indicators has been quantified for different groups of energy products and compared with an energy indicator frequently used (i.e. EROI). A coherent assessment of the depletion of energy resources and of the energy profitability of the products is presented. The indicators could even contribute to understand the feasibility of energy projects and plans by evaluating their impact on the stock of energy resources.
