A programação econômica para a manufatura do pescado de origem extrativista como estratégia competitiva. / The economic programming for the manufacture of the origin extractivist fishing as competitive strategy.Schroeder, Ivanir 11 August 2008 (has links)
O setor pesqueiro brasileiro é representativo e pode contribuir ainda mais com a expansão da riqueza, porém enfrenta muitos desafios. Na revisão da literatura foram encontradas poucas pesquisas relacionadas à gestão econômica de empresas que manufaturam o pescado. As pesquisas encontradas se limitaram a explorar e descrever os problemas da atividade pesqueira no Brasil. Assim, este estudo buscou responder ao seguinte problema de pesquisa: como projetar a lucratividade da operação da manufatura do pescado de origem extrativista, diante das incertezas no fornecimento de matéria-prima e das oscilações dos preços na venda do pescado? Quanto ao objetivo geral buscou-se propor uma programação econômica para o sistema de operação das empresas de manufatura do pescado de origem extrativista. O método que caracterizou essa pesquisa foi o estudo de caso, combinado com elementos do método da pesquisaação. A coleta de dados foi realizada por meio da técnica de triangulação, compondo-se de entrevistas exploratórias, análise documental/bibliográfica e pela observação livre. As variáveis delineadas pela pesquisa e que sustentam o modelo econômico proposto são: a incerteza no preço, quantidade e na qualidade da oferta de matéria-prima; as oscilações no preço de venda; a desarticulação da cadeia produtiva; os reduzidos incentivos à pesquisa e a dificuldade na obtenção de crédito. Foi realizado o teste do modelo econômico descritivo de Brunstein (2005) que utiliza o sistema de custeio direto e o método de margem de contribuição. O teste do modelo foi realizado em uma empresa de manufatura de pescado de origem extrativista, que contempla as variáveis delineadas pela pesquisa e que utiliza processamentos diferenciados na manufatura do pescado. O modelo econômico proposto pode ser útil ao proporcionar critérios de escolha para alternativas de ação ao apoiar o processo decisório dos gestores, ampliando a competitividade das empresas no setor. Ressalta-se que o modelo econômico de Brunstein (2005) pode contribuir com empresas do setor pesqueiro, pois possibilita a flexibilização das variáveis necessárias para análise e tomada de decisão na manufatura do pescado. / The Brazilian fishing sector is significant and could contribute even more to the expansion of wealth. However, it faces challenges. In the literature review, few studies were found relating to the economic management of fish processing companies. Those that were found were restricted to exploring and describing the problems of fishing activity in Brazil. This study therefore seeks to answer the following research problem: how to forecast profitability in the operation of processing the fish catch of extractivist origin, faced with the uncertainties in the supply of raw material, and the variations in sale prices of fish? In terms of general objective, it sought to provide an economic programming for the operating system of companies which process fish of extractivist origin. The method that characterized this research was a case study, combined with elements of the research-action method. The data collection was carried out using the triangulation technique, comprised of exploratory interviews, documentary/bibliographic analysis and free observation. The variables outlined by the research, and which support the proposed economic model, are: price uncertainties, quantity and quality of the offer of raw material; variations in sales price; lack of communication between the various sectors of the production chain; the lack of research incentives, and the difficulty obtaining credit. The descriptive economic model of Brunstein (2005) was tested, which uses the direct costing system and the method of contribution margin. The model was tested in a plant which processes fish of extractivist origin, and considers the variables outlined by the research, using differentiated forms of processing in its production. The proposed economic model can be useful for providing criteria of choice for alternative actions, to support the decision-making process of managers, thereby increasing the competitiveness of companies in the sector. It emphasizes that the economic model of Brunstein (2005) can contribute to companies in the fishing sector, as it enables the increased flexibility of the variables necessary for decision-making in the fish processing industry.

Economic model of mine closure and its potential for economic transformationToni, 07 April 2015 (has links) (PDF)
In Indonesia, the various mining commodities and the amount of resources and reserves are promising, as evidence there are numerous large-scale mining companies and small-scale mines in operation. In 2014 there were 41 companies that held the CoW (mineral contract of work) and 13 companies active in production; and 76 CCoW (coal contract of work) holders, and 57 companies active in production. As well as this, there are more than a thousand small-scale mining companies active for mining commodities. However, mining commodities provide a resource that is not renewable. This will potentially lead to prolonged problems when mining companies do not adhere to good mining practices, particularly in the closing stages of the mine.
Mine closure is the final stage in the process of mining activity. In certain circumstances, closure activities can take a long time and of course can have huge costs. In fact, at this stage, the company is no longer making profit, only incurring costs for the project closure. To prevent problems that may arise after the mine is closed, such as abandoned post-mining land, and the bankruptcy of the company at the end of mining operations, etc., then through specific rules, ie rules of the Minister of Energy and Mineral Resources No. 18 of 2008, the mining company in Indonesia must provide a certain amount of money as a financial guarantee to finance the planned closure project; it must be approved by the government before entering this phase.
However, problems are encountered in practice. The government may become overloaded because they have to quickly make a decision on the closure plan submitted by the company. So a tool is needed that can be used to assess the feasibility as soon as the mine closure plan is proposed by a company, these tools can provide an overview and a variety of options for decision making. In this dissertation methodology was developed to create a systems dynamic model of mine closure.
The model developed can be applied to a variety of mining methods and for various mining commodities. The model can be used to determine the closure costs, to choose the closure project-financing scenario, and up to micro and macro economic analysis of mining activities in the region.
In the case studies conducted in this dissertation, the best scenario of the mine closure planning is to include the everlasting fund in the form of time deposits, and convert the post-mining land for agriculture. The amount of deposit money is about USD 358,986,500 should be spare at the end of mine production, and the total of mine closure cost to be approximately USD 440,757,384.
Agriculture, the economic sector as a substitute for the mining sector, the added value to the GRDP (Gross Regional Domestic Product) is about 0.25 % / a for the province, and 1.68 % for the regency, but the contribution of the mining sector to GRDP was 30% / a at province scale, and 90% / a at regency scale. So that the substitution value is less significant to GRDP growth. However, this scenario is the best scenario among others, due to consideration is the certainty of ecological and economic sustainability. it is the best goal of corporate social responsibility to the environment in the post- mining land.

L'usage en partage : Analyse comparative des modèles socio-économiques d' "économie de (la) fonctionnalité" et d' "économie collaborative" / Shared use : A comparative analysis of the socio-economic models called « functional economy » and « sharing economy »Sidoli, Yoann 20 March 2017 (has links)
Parmi les désignations qui fleurissent dans la presse économique sous l’appellation attractive de « new business models », deux ont pour point commun de s’appuyer sur une logique de partage de biens : l’ « économie de (la) fonctionnalité » et l’ « économie collaborative ». Elles articulent l’exploitation d’innovations technologiques récentes avec l’évolution de pratiques sociales. Ces approches entendent tirer profit d’une transformation contemporaine des modes de consommation, caractérisée par une désacralisation du rôle accordé aux biens matériels.Notre axe de recherche questionne la construction et la signification de plusieurs modèles socio-économiques a priori tournés vers un développement durable. Bien que la multiplication des désignations sème le trouble dans leurs définitions, chacune d’entre elles peut être reliée à des réseaux d’acteurs distincts. Si les expressions « économie de fonctionnalité » et « économie de la fonctionnalité » ne se distinguent que par un déterminant, elles renvoient à deux approches en tension. De même, alors que le terme « économie collaborative » évoque au moment de son émergence la bannière « peer-to-peer », il se diffuse rapidement pour qualifier une forme de capitalisme connexionniste.Le déploiement des modèles étudiés permet de capter certaines transformations des représentations contemporaines. Le relatif succès des modèles est fonction de la correspondance des idéaux qui y sont attachés avec les faits socio-économiques éprouvés par les acteurs. Évolution des formes de travail, modification des contours de / Among the designations that flourish in the economic press through the attractive name of « new business models » (in English in the text), two of them are specifically based on property sharing : « functional economy » and « sharing economy ». They both connect technological innovations with the evolution of social practices. These approaches intend to take advantage of a contemporary transformation of consumption patterns, characterized by a desecration of the role given to material goods.Our research focuses on the construction and meaning of several socio-economic models, in principle aiming to foster sustainable development. Although the multiplication of designations muddles the definitions of the models, each of them is connected to its own network of actors. Even if the French translations for « functional economy », « économie de fonctionnalité » and « économie de la fonctionnalité », are distinguished only by a definite article, they refer to two contradictory approaches. Similarly, while the term « sharing economy » firstly evokes the « peer-to-peer » (in English in the text) banner, it rapidly spreads to describe a form of connexionist capitalism.The deployment of the studied models makes it possible to capture certain transformations of contemporary representations. The relative success of the models depends on the correspondence of the ideals attached to each of them and the socio-economic facts experienced by actors. Evolution of work, changes in the outlines of property or distrust towards the political class are revealed by the analysis of discourses related to our topics.

Modèle économique de l'information écrite à l'ère numérique. Peut-on encore créer de la valeur ? / Economic model for print media in the digital age. Is it still possible to create value ?Lablanche, Pascal 02 April 2012 (has links)
Alors que la création de valeur demeure un objectif légitime et naturel de l’évolution d’une firme, cette recherche a montré que les éditeurs de presse d’information se trouvent, depuis le début du XXIe siècle, d’une part, dans une situation financière dégradée et subséquemment dans une spirale de destruction massive de valeur au point de mettre en péril leur pérennité – certains étant d’ailleurs en faillite virtuelle – et, d’autre part, dans l’incapacité à l’horizon 2016, au-delà du simple équilibre opérationnel, d’inverser la tendance, dès lors que le raisonnement se conduit à périmètre structurel constant. Pour autant, en considérant une interdépendance systémique de plusieurs facteurs d’influence – des déterminants de la performance qui puisent leur origine dans l’histoire et la nature même du bien informationnel et qui s’enrichissent d’éléments structurels et environnementaux –, et en acceptant que chaque industrie ne soit plus que le maillon d’une chaîne de valeur globale dans laquelle l’éditeur n’a plus le monopole, il ressort, par une mise en scène de différents scenarii construits, entre prévision et prospective, sur une période allant de 2010 à 2020, que les différentes conditions requises pour une dynamique vertueuse, malgré les pierres d’achoppement possibles, s’articulent autour de trois axes majeurs – reconquête des marchés, recherche de marges de manoeuvre opérationnelles et financières, changement de référentiel. La dynamique se construit dans un enchaînement de circonstances contraint, ajusté et structuré en trois grandes étapes, qui permet finalement à quelques groupes de se réorganiser pour constituer des firmes de taille critique et ainsi dégager, grâce à une équation de valeur efficiente, simplement réajustée et différenciée, les moyens de migrer vers ce nouveau paradigme informationnel né de cet univers numérique. / Creating value is the natural aim of any private company. This study shows however that from the beginning of the 21st century print media publishers have been losing money and getting into a spiral of value-destruction so vicious as to jeopardise their very survival. Some are practically bankrupt. Nor is there any sign they will have turned the corner or even be breaking even by 2016 if the industry doesn’t restructure. There are three ways for print media firms to turn this round and regain positive momentum: recapturing market-share, improving their operational freedom and their margins and changing market perception. To do this however they will need to understand and take account of some big and interrelated themes – the ways in which the new uses of data, its ‘history’, its location and its very nature have enriched the value of information itself. They will also need to accept that publishers no longer have a monopoly of information and that they are only a link in a global value chain. To reach this conclusion the study runs a range of scenarios comparing confident short term forecasts and foresights for the longer term, from 2010 to 2020. We find that there will probably be three key stages of constraint, change and restructuring. A few publishers probably will manage to reorganise themselves, reach critical size and create value in this new world. To do so they will have a profoundly new and efficient value-creation ‘equation’, readjusted and differentiated from what has gone before. It is this that will allow them to migrate into and flourish in the new informational paradigm born from this digital universe.

Objetivos de seleção e valores econômicos para bovinos Nelore em sistema de ciclo completo / Breeding Objectives and Economic Values for Nellore Cattle in a Full-Cycle SystemMoreira, Heverton Luís 15 September 2015 (has links)
O objetivo do presente trabalho foi definir os objetivos de seleção e estimar os valores econômicos para característica de importância econômica em um sistema de bovinos de corte criados em regime de ciclo completo, além de estimar os parâmetros genéticos para características produtivas, reprodutivas e de qualidade de carcaça avaliadas no programa de seleção Nelore Brasil. O desenvolvimento do modelo bioeconômico foi realizado considerando as informações do sistema de produção e dos parâmetros biológicos com objetivo de estabilizar o rebanho e calcular o número de animais em cada categoria, obter as informações de desempenho produtivo e econômico (receita e despesas) do sistema pecuário, e por fim a obtenção dos valores econômicos das características contidas no objetivo de seleção em sistema de ciclo completo, que para tal, foram utilizadas planilhas interligadas do programa Microsoft Excel®. Os valores econômicos foram estimados simulando o aumento de 1% no valor da característica do objetivo de seleção, mantendo as demais constantes. A estimação dos parâmetros genéticos foi pelo método de Máxima Verossimilhança Restrita (REML) usando o modelo animal, utilizando o software WOMBAT e o ganho genético anual para as características de reprodução, carcaça e desenvolvimento ponderal foi estimado pela regressão linear do valor genético (VG) em função do ano de nascimento. O modelo bioeconômico foi eficaz na estimação das fontes de receitas e despesas do sistema de produção e os valores econômicos estimados seguindo a ordem de importância para o ciclo completo foram R$ 3,69 para peso ao abate de macho (PAM), R$ 3,63 para peso a desmama de macho (PDM), R$ 3,58 para taxa de desmama (TD), R$ 3,40 para peso ao abate de fêmea (PAF), R$ 2,30 para peso a desmama de fêmea (PDF) e R$ 0,13 para peso ao adulto de vaca (PAV). Portanto, o PAM foi à característica de maior impacto no sistema de produção, porém, todas promoveram retorno econômico positivo com exceção do PAV que foi praticamente nulo. As estimativas de herdabilidade para as características de produção, reprodução e qualidade de carcaça foram favoráveis ao progresso genético por seleção direta. As correlações estimadas demonstram que machos com maior perímetro escrotal tendem a ser mais pesados e esses apresentarem maior rendimento e acabamento da carcaça. O processo de Resumo 13 seleção empírica utilizado pelo programa Nelore Brasil está sendo eficiente, de acordo com os resultados positivos dos progressos genéticos nas estimativas de tendência. Portanto todas as características avaliadas no sistema de ciclo completo tiveram importância econômica positivas, indicando que o processo de seleção trariam aumentos de lucratividade e as avaliadas geneticamente poderiam ser incluídas como critério de seleção contribuindo com a maximização da resposta esperadas para as características do objetivo de seleção. / The objective of this study was to define the objectives of selecting and estimating economic values for characteristics of economic importance in a system of beef cattle raised in fullcycle scheme. We also aimed to estimate the parameters for genetic reproductive and productive characteristics of carcass quality evaluated in the breeding program Nellore Brazil. The bio-economic model was developed considering the information and production system of biological parameters to stabilize the herd and calculate the number of animals in each category, obtain information on economic performance (revenue and expenses) of the livestock system, and finally to obtain economic values of the characteristics contained in the objective of selection in full-cycle system. We used interlinked spreadsheets in the Microsoft Excel®. The economic values were estimated by simulating the increase of 1% for the value of the characteristic of objective selection, keeping the others constant. The estimation of genetic parameters was obtained by the method of Restricted Maximum Likelihood (REML) using the animal model in the WOMBAT software and genetic gain for annual breeding characteristics; weighted carcass and development were estimated by linear regression of genetic value (GV) depending on the year of birth. The bio-economic model was effective in estimating revenue and expenditure sources of the production system and the estimated economic values, following the order of importance for the complete cycle, were R$ 3.69 for slaughter weight of male (SWM), R$ 3.63 for weaning weight of male (WWM), R$ 3.58 for weaning rate (WR), R$ 3.40 for the slaughter weight of female (SWF), R$ 2.30 for weaning weight of female (WWF) and R$ 0.13 for adult cow weight (ACW). Therefore, SWM had the greatest impact on the production system, however, all aspects promoted positive economic return with the exception of ACW, which was practically null. Heritability estimates for production, reproduction and carcass characteristics and quality were favorable to genetic progress for direct selection. The estimated correlations demonstrate that males with larger scrotal perimeter tend to be heavier and have higher carcass yield and finishing. The empirical selection process used by the program Brazil Nellore is efficient, according to the positive results of the genetic progress in trend estimates. Therefore, all features evaluated in the fullAbstract 16 cycle system had positive economic importance, indicating that the selection process could bring gains in profitability and the genetically evaluated characteristics could be included as a breeding criterion, contributing to the maximization of the expected response for the traits of interest in breeding programs.

A Determination of the Association of Competition and Regulation With Hospital Strategic OrientationHeatwole, Kathleen B. 01 January 2006 (has links)
This research study examines the influence of two major forces, competition and regulation, on the strategic orientation of hospitals. This is a particularly relevant subject, as the effectiveness of competition versus the effectiveness of regulation in the health care market has been called one of the Bellwether issues in health care policy, and the most controversial and far reaching philosophical battle facing the health care industry. Even after three decades of research and debate, there is still no consensus on how the hospital industry responds to either a competitive environment or a regulated environment. There continues to be significant variation across the country on which model provides the environmental context for hospitals, and there is no resolution of the issue on the horizon. It is clear that the dichotomy of a competitive environment or a regulated environment and the wide variation from market to market will continue to be significant factors influencing the development of hospital strategies. Developing strategies that provide an appropriate fit with the particular environmental context is a critical aspect of the success of an organization.This study provides a unique perspective on the subject, with an examination of the relationship between the level of competition in the market and the level of regulation in the market, and whether these dimensions influence hospital strategic orientation. Porter's strategic orientation typology is used as the model for hospital strategy, and the theoretical framework combines the legitimacy seeking elements of institutional theory and the resource and cost control elements of resource dependency theory.The findings of this study indicate an association between a competitive environment and a differentiation orientation. As competition decreases, there is a greater likelihood of association with cost inefficiency. The results also indicate that in the absence of CON or as CON decreases, there is a greater likelihood of cost inefficiency. Although this study provides a timely analysis of a very controversial topic, it is clear that additional research efforts are needed on this critical issue that impacts every hospital in the country.

Assessing the Tradeoffs of Water Allocation: Design and Application of an Integrated Water Resources Model2015 November 1900 (has links)
The Bow River Basin in Southern Alberta is a semi-arid catchment, with surface water provided from the Rocky Mountains. Water resources in this basin, primarily surface water, are allocated to a variety of users- industry, municipalities, agriculture, energy and needs for the environment. The largest consumptive use is by agriculture (80%), and several large dams at the headwaters provide for over 800,000 MWhrs of hydropower. This water is managed by the 1990 Water Act, distributing water via licenses following the “first in time first in right” principle. Currently, the basin is over-allocated, and closed to any new licenses. Conflicts between different water users have consequences for the economy and the environment. By using an integrated water resources model, these conflicts can be further examined and solutions can be investigated and proposed.
In this research an integrated water resources model, referred to as Sustainability-oriented Water Allocation Management and Planning Model applied to the Bow Basin (SWAMPB), is developed to emulate Alberta’s Water Resources Management Model (WRMM). While having the same allocation structure as WRMM, SWAMPB instead provides a simulation environment, linking allocation with dynamic irrigation and economic sub-models. SWAMPB is part of a much larger framework, SWAMP, to simulate the water resources systems for the entire South Saskatchewan River Basin (SSRB). SWAMPB integrates economics with a water resources allocation model as well as an irrigation model- all developed using the system dynamics approach. Water is allocated following the allocation structure provided in WRMM, through operation rules of reservoirs and diversions to water users. The irrigation component calculates the water balance of farms, determining the crop water demand and crop yields. An economic valuation is provided for both crops and hydropower generation through the economic component.
The structure of SWAMPB is verified through several phases. First, the operation of reservoirs with fixed (known) inflows, and modeled releases, are compared against WRMM for a historical simulation period (1928-2001). Further verifications compare the operation of SWAMPB as a whole without any fixed flows but fixed demands to identify errors in the system water allocation. A final verification then compares both models against historical flows and reservoir levels to assess the validity of each model.
SWAMPB, although found to have some minor differences in model structure due to the system dynamics modeling environment, is to be evaluated as an acceptable emulator.
SWAMPB is applied to assess a variety of management and policy solutions to mitigating environmental flow deficit. Solutions include increasing irrigation efficiency (S1), requiring more summer release from hydropower reservoirs at the headwaters (S2), a combination of the previous two (S3), implementing the In-Stream Flow Needs (S4) and implementing Water Conservation Objectives (S5). The solutions are not only examined by their ability to restore river flows, but also with respect to the economic consequences and effect on hydropower, irrigation, and municipalities. It is found that the three technical solutions (S1, S2, and S3) provide economic gains and allow more efficient water use, but do little to restore streamflows. Conversely, the two policy solutions (S4 and S5) are more effective at restoring river flow, but have severe consequences on the economy and water availability for irrigation and municipal uses. This analysis does not recommend a particular solution, but provides a quantification of the tradeoffs that can be used by stakeholders to make decisions. Further work on the SWAMP methodology is foreseen, to link SWAMPB with other models, enabling a comprehensive analysis across the entire SSRB.
