Der volle Inhalt der QuelleOccidental countries currently face an epidemic of obesity and related diseases. As eating disorders and drug addiction are both complex pathologies inducing long-term neuroadaptations, we investigated common alterations induced by either sugar or cocaine intake in reward-related brain regions. We focused our research on the endocannabinoid and opioid systems, as both systems are expressed in the central nervous system and play a crucial role in drug reward and food intake. Overall, our results highlight the hippocampus as a highly involved brain site following cocaine use. Moreover, our work sheds light on epigenetic mechanisms regulating the endocannabinoid system. More importantly, we demonstrate that a binge-like intake of sucrose induced similar transcriptional adaptations to that of voluntary cocaine intake in the nucleus accumbens. These findings may pave the way to new therapeutic targets for addictive behaviors
Vesterberg, Iris, und Sofia Westerlund. „Hybridization with CSP in a Cuban sugar mill“. Thesis, KTH, Energiteknik, 2018. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-233214.
Der volle Inhalt der QuelleCuba is currently highly dependent on imported oil, mainly from Venezuela, to meet their growing electricity demand. This dependence makes Cuba sensitive to changes in oil price as well as the political climate. The current crisis in Venezuela has a large impact on Cuba’s electricity generation. By expanding its renewable energy sources Cuba could decrease their dependence on other countries and diversify their energy supply. Moreover, it would have a positive climate impact by reducing the country’s CO2-emissions. Geographically, Cuba has ideal conditions for renewable energy utilization, such as solar power. Solar energy is constantly progressing and is considered a great source of energy. Concentrating Solar Power (CSP) is a technology which applies mirrors and/or lenses to concentrate the sunlight onto a small area which converts the sunlight into heat, possible to use in a thermodynamic cycle. There are mainly two problems with the implementation of CSP in Cuba. Firstly, CSP is a non-dispatchable power generating system since it is dependent on the instantaneous weather conditions. Secondly, it has high investment costs. One way of solving these problems is by implementation CSP in an already existing power plants with a dispatchable source of energy, making it a hybrid power plant. Accordingly, the hybrid power plant would be dispatchable and the investment costs would be significantly lower. Existing power plants can be found in Cuban sugar mills. This study investigates the possibility to implement solar power in the sugar mill Carlos Baliño, located in Villa Clara, Cuba. The factory is currently self-sufficient electricity wise on a yearly basis, using a co-generation Rankine cycle to generate electricity and process heat used in the sugar production. The fuel used is bagasse, a rest product obtained after the sugar juice has been pressed out of the sugar canes. Four CSP-technologies and three implementation layouts were examined, resulting in the parabolic trough-technology and feedwater heating being considered the optimal solution. Furthermore, two different scenarios for CSP was investigated; implementation of CSP in the mill at the current state (scenario 1) or after investing in a Condensing-Extraction Turbine (CEST) (scenario 2). The results show that Carlos Baliño should invest in a CEST before considering implementation of CSP. Off-season operation is not available for scenario 1, leading to a vast amount of solar potential being unexploited. The maximal investment allowed for scenario 1 is 3.7 MUSD, which is not a realistic number. The maximal investment allowed for in scenario 2 is 5.9 – 7.2 MUSD, depending on bagasse import availability. If bagasse import is unlimited, it is not recommended to invest in solar power. Implementation of CSP in scenario 2 regarding bagasse import limits would yearly lead to an additional electricity generation at Carlos Baliño of 5.4 – 7.3 GWh, decrease the oil usage with 16,100 – 21,800 barrels and the CO2-emissons with 1,200 – 1,600 tonnes. Carlos Baliño’s annual yield would increase with 0.5 – 0.6 MUSD/year and the Cuban states annual yield would increase with 0.7 – 0.9 MUSD/year. Future work is recommended to explore alternatives to all year-around electricity generation in Carlos Baliño without investing in a CEST, investigate solar power demand on a national level, and examine possible developments of the suggested solar field, for instance solar-only operation.

Resumo: Com a primeira crise do petróleo, em 1973, houve necessidade de buscar fontes alternativas de energia que pudessem substituir os derivados de petróleo. Assim, o Programa Nacional do Álcool ¿ ProÁlcool foi instituído com a emissão do Decreto nº 76.593, de 14 de novembro de 1975, baseando-se, inicialmente, na produção de álcool anídro para misturá-lo à gasolina. Com a nova crise do petróleo, em 1979, além da mistura à gasolina, iniciou-se a fabricação de automóveis movidos a álcool. Isto intensificou a agroindústria canavieira, responsável por impactos ambientais como a destruição de áreas com mata nativa, perda da diversidade da produção rural e lançamento de vinhaça nos rios. Ainda hoje, tais impactos geram problemas ambientais e sociais como: erosão e poluição dos solos, poluição dos recursos hídricos por agrotóxicos, emissão de poluentes na atmosfera pela queima dos canaviais, destruição da biodiversidade e aumento do êxodo rural. Como contrapartida positiva, a adoção do álcool combustível melhorou a qualidade do ar nas cidades brasileiras, substituindo substâncias tóxicas nos combustíveis de veículos automotores. Assim, a relação custo/benefício merece um estudo aprimorado, uma vez que esta indústria é afetada pelas novas possibilidades tecnológicas. Este trabalho analisa possibilidades alternativas da produção da cana-de-açúcar e fabricação de açúcar e álcool, agrupadas como tendências que podem melhorar a produção e diminuir os impactos ambientais da atividade canavieira. Entre elas destacam-se aquelas relacionadas às disposições legais, às inovações tecnológicas e às forças de mercado. A análise da produção da cana, do açúcar e do álcool baseou-se em dados coletados em usinas do estado de São Paulo e, a partir destes dados, foi verificado como a aplicação destas tendências afetaria a agroindústria. A ferramenta escolhida para realizar esta análise foi à metodologia emergética, que permite avaliar os impactos ambientais do sistema de produção, verificando os índices relacionados ao uso de recursos renováveis e não renováveis, os serviços ambientais locais, os serviços econômicos e a rentabilidade econômica do sistema. Baseando-se na metodologia, as vantagens e desvantagens de cada tendência foram identificadas de acordo com o aproveitamento dos recursos naturais renováveis e não-renováveis, materiais e serviços. Das tendências analisadas, a que obteve melhores índices foi a agricultura orgânica. Como previsto, esta técnica aproveita melhor os recursos naturais, agredindo menos o solo e o meio ambiente. Outra vantagem verificada foi à necessidade intensiva de mão-de-obra rural. Esta técnica oferece benefícios ambientais, por ser menos poluidora, e benefícios sociais, pois mantém o emprego dos trabalhadores rurais. Por outro lado, a que se mostrou menos sustentável foi à mecanização da colheita, devido à necessidade de maiores investimentos em equipamentos, tecnologia e combustíveis. É importante ressaltar que cada tendência foi estudada isoladamente, sendo importante realizar simulações com duas ou mais tendências. Com a incorporação de mais tendências na mesma atividade os impactos ambientais e sociais tendem a diminuir, melhorando a produtividade da agroindústria canavieira
Abstract: With the first crisis of the oil, in 1973, it had necessity to search alternative energy sources that could substitute the oil derivatives. Thus, the Alcohol National Program ¿ ProÁlcool ¿ was instituted with the emission of the Decree n° 76,593, of November 14, 1975, being based, initially, in the anhydrous alcohol production to be mixed to gasoline. With the new crisis of the oil, in 1979, beyond the mixture to the gasoline, it was initiated the manufacture of automobiles moved by alcohol. This intensified the sugar cane agricultural industry, responsible for environmental impacts such as the destruction of areas with native forest, loss of the agricultural production diversity and launching of vinasse in the rivers. Still today, these impacts generate environmental and social problems such as: ground erosion and pollution, pollution of the hydro resources with pesticides, pollutants emission in the atmosphere with the cane-plantation burning, biodiversity destruction and increase of the agricultural exodus. As positive counterpart, the adoption of the combustible alcohol improved the quality of air in the Brazilian cities, substituting toxic substances in automachine vehicles fuels. Thus, the cost/benefit relation deserves an improved study, because this industry is affected by the new technological possibilities. This work analyzes alternative possibilities of the sugar cane production and sugar and alcohol manufacture, grouped as trends that can improve the production and diminish the environmental impacts of the sugar cane industry activity. Among them those related to the legal disposals, to the technological innovations and to the market forces are distinguished. The analysis of the sugar cane, sugar and alcohol production was based on data collected in industries in the state of São Paulo and, from these data, it was verified how the application of these trends would affect the agricultural industry. The chosen tool to carry through this analysis was the emergy methodology, that allows the evaluation of the environmental impacts of the system production, verifying the index related to the utilization of renewable and non-renewable resources, the local environmental services, the economic services and the economic yield of the system. Being based on the methodology, the advantages and disadvantages of each trend had been identified in accordance with the exploitation of the renewable and non-renewable natural resources, materials and services. In the analyzed trends, the one that got better index was the organic agriculture. As foreseen, this technique takes advantage of the natural resources better, attacking little the ground and the environment. Another verified advantage was the intensive necessity of agricultural manpower. This technique offers environmental benefits, for being less polluting, and social benefits, because it keeps the job of the agricultural workers. On the other hand, the one that showed less sustainability was the harvest mechanization, due to necessity of bigger investments in equipment, technology and fuels. It is important to stand out that each trend was studied separately, being important to carry through simulation with two or more trends. With the incorporation of more trends in the same activity the environmental and social impacts tend to diminish, improving the productivity of the sugar cane industry

Der volle Inhalt der QuelleDie voormalige minister van finansies het in sy begrotingstoespraak in 2016 vermeld dat suikerbelasting vanaf 1 April 2017 in Suid-Afrika in werking gaan tree. Die tesourie se rede vir die implementering van suikerbelasting is om, in samewerking met die Departement van Gesondheid, die gesondheidsprobleme wat deur suiker veroorsaak word te verminder. Dit is niks nuuts om fiskale maatstawwe te gebruik om beide belasting in te vorder en gesondheidsprobleme te voorkom nie, maar dit was nog nie moontlik om tot ’n definitiewe gevolgtrekking te kom oor die impak van suikerbelasting op die verbruik van suikerversoete drankies en die voorkoms van vetsug nie. Die rede hiervoor is dat daar bewyse is dat die implementering van voedselbelasting in verskillende lande verskillende resultate getoon het in terme van openbare gesondheidskwessies en belastingvoordele. In Suid-Afrika kan die implementering van suikerbelasting óf die voorkoms van vetsug verminder en sodoende die ekonomie bevoordeel óf die implementering daarvan kan die ekonomie negatief beïnvloed. Indien die tesourie nie suikerbelasting implementeer nie kan die ekonomie as gevolg van die voorkoms van vetsug negatief beïnvloed word. Die kern van hierdie skripsie handel oor die gevolge van nieoordraagbare siektes en suikerbelasting op die Suid-Afrikaanse ekonomie. Daar word spesifiek gefokus op hoe suikerbelasting internasionaal geïmplementeer word en hoe Suid-Afrika beoog om suikerbelasting te implementeer.

Der volle Inhalt der QuelleEnergisystem är av stor betydelse för samhällsutveckling, inte minst i utvecklingsländer. Ett väl utvecklat energisystem kan bidra till ekonomisk, ekologisk så väl som social hållbarhet. Samtidigt ökar ambitionerna om att globalt minska beroendet av fossilbaserade bränslen samt de klimatpåverkande utsläppen som följer med dessa. För att uppnå detta krävs energieffektiviseringar och en ökad andel förnyelsebara energikällor. Idag finns både stora utmaningar och möjligheter i att utveckla energisystem i utvecklingsländer och samtidigt minska klimatpåverkan globalt. Tack vare sockerindustrin på Kuba finns stora möjligheter för landet att utveckla dess elproduktion från biobränsle i form av bagass, en restprodukt som tillhandahålls i framställningen av socker. I denna rapport undersöks möjligheten att utveckla energisystemet i sockerbruket Carlos Baliño, beläget i Villa Clara på Kuba. Syftet är att möjliggöra för verksamheten att minimera dess användning av bagass samt maximera elproduktionen. Detta för att ge möjlighet för sockerbruket att bli mer ekonomiskt och ekologiskt hållbart. Det nuvarande energisystemet i sockerbruket undersöktes och en modell av energiflödena skapades i Excel. Utifrån det nuvarande energisystemet undersöktes därefter fyra olika scenarier med potentiella förbättringar. Dessa fyra scenarier var följande; (1) Förvärmning, (2) Bagasstorkning, (3) Höjning av tryck i pannan samt (4) Investering av ny generator. För de olika scenarierna framtogs dess energiflödesscheman samt tekniska komponenter. En ekonomisk samt ekologisk analys utifrån scenariernas bästa möjliga parametrar utfördes sedan. Resultatet visade att det marginella elbehovet för det nuvarande systemet är 19 kWh per ton sockerrör samt att det fasta elbehovet är 890 kW. Med modellen definierades värdet på bagassen som 8,2 USD per ton, utifrån det nuvarande systemet. Den nuvarande besparingen av kostnader genom att ersätta olja definierades till 31 MUSD och den totala mängden besparade koldioxidutsläpp som 96 ton, båda under en period på 6 år. Av de fyra scenarier som utreddes och jämfördes med nuvarande system var torkning av bagass det alternativ som bäst kunde motiveras. Detta scenario resulterade i ett värde på bagassen av 5,0 USD per ton, en minskning av kostnader om 51 MUSD genom att ersätta olja under en 6 års period samt 150 000 ton besparade koldioxidutsläpp under samma period. Förvärmning resulterade i en ökning av bagassförbrukning, men även en högre elproduktion. Resultatet visade även att en höjning av trycket i pannan ej är relevant, då det nuvarande trycket är näst intill maximalt för det nuvarande systemet. På grund av en förenklad modell kunde Scenario 4, vilken innefattade investering av en ny generator, ej testas.

Der volle Inhalt der QuelleThe Sugar Industry in Fiji is facing a lot of problems. Since the Government of Fiji has not fulfilled their commitments to the European Union (EU), the EU has backed away from supporting the industry. The milling efficiency has been constantly declining since the mid 1980’s and farm productivities have not kept pace with the changing international market for sugar. To be able to obtain the economies of scale, the sugar production in Fiji has to increase with 75 % from the current level of production. A lot of towns in Fiji would be nothing without the Sugar Industry, and thousands of people are dependent on the industry for their sustenance. Due to this fact, it is certain that the loss of confidence in the industry, or any likely collapse, would imply disaster for Fiji as a whole. It will lead to serious implications on the economic, social and political stability of Fiji.
The overall aim of this thesis is to study the effects of the EU measures especially on the Sugar Industry in Fiji, to be able to understand to which extent the industry depends on the support from the EU. The aim is also to analyse and discuss different competition strategies on how Fiji can compete and be a part of the global market of sugar.
This research was made from a qualitative approach in order to gain a deeper understanding about the problem. Abduction made it possible to work parallel with different parts of the thesis. A combination of primary and secondary data gathering has been used, with the secondary data as a basis for building the empirical part of the thesis. The primary data was collected through in-depth interviews with people at different positions within the Sugar Industry in Fiji.
Fiji is dependent on the Sugar Industry and since there is no other obvious donor for Fiji today, and it is crucial that the industry gets support, the conclusion is that Fiji also is dependent on the support from the EU. Even though Fiji has the possibility to increase their competitiveness on the regional as well as on the international market, there is no need for Fiji to strive after the world market at the moment.

A agroindústria canavieira tem sido, ao longo da história do Brasil, uma das atividades mais importantes da economia brasileira. A perspectiva da introdução do álcool carburante como commodity mundial e fonte de energia renovável coloca novamente o setor em evidência. No entanto, pelas suas características técnico-produtivas e extensão, o setor tem sido alvo de muitas críticas. Apesar disso, como as perspectivas para o setor são de crescimento, há impactos econômicos e sociais sobre as cidades onde essa agroindústria está instalada. No passado recente, algumas cidades se desenvolveram baseadas na agroindústria de cana de açúcar, como, por exemplo, Ribeirão Preto, Piracicaba, Araraquara, Sertãozinho e Jaboticabal. Examinar o crescimento dessa agroindústria e o crescimento de renda e a qualidade de vida é o objetivo deste trabalho. O enorme crescimento recente do plantio de cana no Estado de São Paulo, em detrimento de outras atividades agrícolas, justifica este trabalho, que se atém à região de Jaboticabal, uma das principais regiões canavieiras do Estado de São Paulo

Resumo: Este trabalho teve por objetivo analisar como se deu a passagem da situação do Bóia-Fria na condição de trabalhador-morador para trabalhador-credor, a partir das mudanças operadas nas condições de trabalho, quando da institucionalização da CLT - Consolidação das Leis Trabalhistas - como Regime de Trabalho e suas consequências. A análise histórica foi desenvolvida com foco nos Engenhos de cana-de-açúcar do Estado de Pernambuco. A pesquisa, numa abordagem sócio-antropológica permitiu conhecer a gênese do Bóia-Fria, desde o período do Brasil Colônia até os dias atuais, onde se desenvolveram suas relações sociais e de trabalho, suas lutas pela sobrevivência e reconhecimento social. Permitiu ainda, conhecer com base nos fundamentos da Ergonomia, o trabalho desenvolvido pelo Bóia-Fria nas perspectivas física, psicológica e cognitiva, cujos resultados apontam para uma categoria de trabalhador rural em vias de extinção em decorrência do avanço da mecanização no corte da cana. O alto índice de analfabetismo se apresenta como um vetor natural para o aproveitamento dessa categoria em outras atividades que não sejam àquelas relacionadas ao cultivo e corte da cana-de-açúcar, o que sinaliza grande dificuldade de inserção social e mudança qualitativa de vida
Abstract: The present work had as the main goal to analyse the shifting condition of the part time workers ("bóia-fria") due to the creation of the labour law (CLT - Consolidação das Leis Trabalhistas) and the consequences, when he abandons the farm as his place of living. The historical analysis was developed aiming the sugar cane production and processing system in the state of Pernambuco. Through a social anthropological approach, this research tried to understand the origin of the part time workers ("bóia-fria") since when Brazil was a colony to nowadays, how the working conditions and social relations had developed and changed, and their survival struggle and social acknowledgement. This work also investigated, based on the Ergonomics basics, the work developed by the part time workers ("bóia-fria"), in physical, psychological and cognitive viewpoints. The results point to a rural worker category close to extinction due to the advancement of the mechanization of the sugar cane harvesting. The high index of illiteracy presents itself as a natural vector to the reapplication of this category in other activities not related to sugar cane harvesting, pointing a great difficult of social insertion and qualitative chance of life

Der volle Inhalt der QuelleThe present work is aimed at evaluating a group of proposed analytical-descriptive and performance indicators in Brazilian agro-industry sugarcane fleets. Brazil is the worlds greatest sugarcane producer (Lucchesi, 1995) and this activity employees 3% of the rural labor in the country (Paixão, 1994). The data for testing the proposed group of indicators were collected by means questionnaires filled in by sugarcane agro-industries between 1998 (1997/1998 crop) and 2000 (1999/2000 crop). The number of companies involved in the research were 67, 73 and 73 during the 1997/1998, 1998/1999 and 1999/2000 crops, respectively. The results showed that the evaluated indicators can be used as an effective toll for sugarcane fleets management, besides evidencing an aging tendency of the fleets between 1997/1998 and 1999/2000, as well as an increase in outsourcing. The results also showed a trend toward mechanized planting and mechanized harvest in sugarcane enterprises.

Traditionally, the sugar cane sector is commodities industry and rarely innovate its portfolio, although researches have shown that some firms inside the sector have been using portfolio diversification strategies in the search of growth. Inside these strategies, the firms have made choices to: prospect new knowledge (exploration) or take advantage of not utilized competencies (exploitation). The use of knowledge is part of sectoral systems of innovation due to actors and institutions interaction. Using an exploratory and multicase and multistrategy study, this project wants to verify which processes exploration or exploitation is predominant on diversification strategy of sugar cane firms. The main contribution of this study are related to three main objectives: (1) identify characteristics of diversification in the sugar cane plants; (2) distinguish the processes of exploration and exploitation in these plants; (3) present evidences that support the presupposition of sugar cane sector being a sectoral systems of innovation. The results have shown that, from a total of nine firms, eight of them developed diversification strategies, related to Penrose (1959) classification of diversification. All of them participated in the sectoral systems of innovation, interacting in major or minor degree. All researched firms presented process related to exploitation, but their punctuation in exploration may explain their search for diversification. The high punctuation at exploration of some firms suggests it may be an explanation of their differentiated portfolio. Furthermore they showed intensive interaction with universities and research entities, in the search for new knowledge. These findings where consistent with the main objective defined in this project. It is expected that the present study might support future researches upon knowledge generation in firms oriented to diversification strategies.
Tradicionalmente, o setor sucroalcooleiro é um produtor de commodities e raramente inova sua carteira de produtos, embora algumas pesquisas demonstrem que firmas dentro do setor têm usado estratégia(s) de diversificação destas carteiras para buscar crescimento. Para atingir esta(s) estratégia(s), as firmas fazem escolhas entre: prospectar conhecimento novo (exploration) ou aproveitar competências não utilizadas (exploitation). O uso do conhecimento é característico dos sistemas setoriais de inovação devido à interação entre seus atores e instituições. Através de um estudo exploratório, mediante a aplicação de estudo multicasos e pesquisa de múltipla estratégia (quantitativa e qualitativa), buscou-se verificar qual dos processos exploration ou exploitation predomina na estratégia de diversificação das firmas sucroalcooleiras. As principais contribuições deste estudo relacionaram-se a três objetivos específicos: (1) identificar características de diversificação presentes nas usinas estudadas; (2) caracterizar os processos de exploration e exploitation nessas usinas; (3) apresentar argumentos que suportem o pressuposto de que o setor sucroalcooleiro é um sistema setorial de inovação. Os resultados apontaram que oito entre nove usinas pesquisadas apresentaram algum tipo de diversificação, de acordo com a classificação de Penrose (1959). Todas as usinas apresentaram participação no sistema setorial em menor ou maior grau e processos voltados à exploitation, mas observou-se que a pontuação em exploration pode ser um fator que explica a busca pela diversificação produtiva. As usinas com valores altos em exploration foram aquelas que apresentaram uma carteira de produtos diferenciada e também nas quais observou-se uma interação maior com universidades e entidades de pesquisa, buscando a prospecção do conhecimento. Espera-se que o presente estudo possa apoiar futuras pesquisas sobre geração de conhecimento em firmas voltadas a estratégias de diversificação.

Der volle Inhalt der QuelleThis work analyzes the institutional framework that mediates market transactions between suppliers (plants) and processing firms (distilleries) within South Central Brazils sugar and alcohol agroindustry. To that end, a comparison is made between institutional production arrangements in traditional and non-traditional sugar cane farming regions. The theoretical background of this investigation is based on the New Institutional Economics, particularly focused on Transaction Cost Economics. The methodology adopted is a departure from the Holistic Approach proposed by Bogetoft and Olesen. In-depth, semi-structured interviews were conducted with producers representing institutions in the sugar and alcohol sector, as well as two case studies on processing firms. Due to the historical development of sugar agriculture, the processing firms and the seven suppliers organizations interviewed are located in different regions. Data collection and information analysis pointed to the existence of different contracts deriving from different institutional arrangements between them. Whereas agricultural producers supplying processing firms in non-traditional regions were observed to be unwilling to sign contracts, those located in traditional ones were found to have stable, long-term relationships governed by verbal contracts based on reputation built along decades of transactions. Conclusions demonstrate the importance of deepening the studies involving institutional arrangements adopted by companies located in different institutional settings.

Der volle Inhalt der QuelleThe proposal of this study is to contribute for the acknowledgment of the competitive generic strategies. So its aim is to analyze the nature of the competitive generic strategies into their main dimensions in order to understand better their role, their importance, and their application onto the strategic process of the organizations. Generic strategies have ever been known since the 1960?s, but from Michael E. Porter?s book in 1980, Competitive Strategy, this theme has been developed through researches, literature, teaching, and practice. It makes up an issue to the content and that matters to the strategic process of the organizations regarding the possibility of better decisions intended to reach their goals and their fitness to the present environment seeking a superior organizational performance. However, the various relevant features as to the theme are generally found throughout the strategic management literature, dependent of a larger and structured approach which explores its main dimensions in a broad and consolidated way, in order to understand its relations and width for a more conscious and effective application into the strategic process of the organizations. This study uses an exploratory research of qualitative nature to achieve its goals, by a bibliographic survey. Consequently, some aspects are studied such as concept evolution, its nature and main features, applications, more important typologies, risks, requisites for the implementation, use of combined strategies, generalization and contingency, role, importance and critics to the concept. To get a deeper study, complement and enrich it, this work was carried out in a field research through a unique and holistic case study, in order to investigate the concept application into a company of the Brazilian sugar industry. The results demonstrate that the concept of generic competitive strategies comes out in Nova América S.A. ? Agroenergia chiefly dressed of differentiation strategy, market development and product development, and has been exercising the roles of organizational leader and facilitator of strategic decision taking process, in the strategic process of the company. Nevertheless Nova América S.A. ? Agroenergia have limitedly applied the generic competitive strategies concept basically in the elaboration of the strategic alternatives, but this concept assumes importance for contributing to positioning in the Brazilian sugar industry, and in offering alternatives of feasible ways on how to compete to a superior organizational performance. The theoretical survey supports the enlightenment of the nature, of the different roles performed, of the applications and of the importance of the concept of generic competitive strategies for the strategic process of the organizations. This study concludes that the approach cannot be disassociated from its various dimensions, relations, and issues for a better understanding of the theme, and we still have the utility and fitness of the techniques of identification and found strategic classification, analyzed and applied into this research. So, the large and structured focus of this dissertation may come to be used as the beginning point for later studies on the phenomenon of the generic competitive strategies as well as source of references for companies and their top management team in order to support and improve their strategic decision taking process.

Resumo: A agroindústria canavieira tem sido, ao longo da história do Brasil, uma das atividades mais importantes da economia brasileira. A perspectiva da introdução do álcool carburante como commodity mundial e fonte de energia renovável coloca novamente o setor em evidência. No entanto, pelas suas características técnico-produtivas e extensão, o setor tem sido alvo de muitas críticas. Apesar disso, como as perspectivas para o setor são de crescimento, há impactos econômicos e sociais sobre as cidades onde essa agroindústria está instalada. No passado recente, algumas cidades se desenvolveram baseadas na agroindústria de cana de açúcar, como, por exemplo, Ribeirão Preto, Piracicaba, Araraquara, Sertãozinho e Jaboticabal. Examinar o crescimento dessa agroindústria e o crescimento de renda e a qualidade de vida é o objetivo deste trabalho. O enorme crescimento recente do plantio de cana no Estado de São Paulo, em detrimento de outras atividades agrícolas, justifica este trabalho, que se atém à região de Jaboticabal, uma das principais regiões canavieiras do Estado de São Paulo

Der volle Inhalt der QuelleHistorically important for the Brazilian economy, the sugar cane has acquired increasing importance since the early 2000s, resulting of growth of world demand for renewable fuels. Simultaneously one can observe an escalation of the Brazilian tax burden over the past 30 years, especially since 1990s. This dissertation aims to analyze qualitatively and quantitatively the major taxes on final goods of Brazilian sugar-ethanol industry, namely sugar and ethanol. For this purpose, its divided into two parts. The first one lists the desirable characteristics of a perfect tax system, and evaluates the presence of these characteristics in the taxes levied on the sugar-ethanol sector. Subsequently, estimates - based on the methodology of payment of each tax - the potential tax burden levied on hydrated ethanol and crystal sugar in all links of their chains in the state of Sao Paulo for the years 2000 and 2008. The results point to a potential tax burden of 23.04% of the final price of hydrated ethanol and 27.39% of the final price of crystal sugar. With the aim of measuring the importance of the exemption of some taxes on foreign sales, this thesis estimates the difference in potential tax burden between ethanol exported and sold to the domestic market. The same is done for sugar. The difference of the tax burden on ethanol exported by the plant and ethanol sold to the domestic market is estimated at 15.65 pp. For sugar this difference is 21.25 pp. Finally, to verify the evolution of the tax burden on the industry, this paper estimates the tax burden on the sector in 2000, what were 40.08% for ethanol and 25.91% for sugar. There is an increasing burden on the sugar and reduce the burden on alcohol.

Tendo em vista as reincidências de casos de libertação de trabalhadores da cana que foram submetidos à trabalhos forçados ou análogos à trabalho escravo. Com o crescimento da população a produção de alimentos cresceu para suprir a demanda populacional. Dentro deste contexto a cultura da cana de açúcar expandiu vertiginosamente por todo o país com intuito de não só suprir as necessidades nacionais. Neste processo produtivo da cana de açúcar afloram as relações trabalhistas advindas da empresa canavieira com seus empregados cortadores de cana. Do ponto de vista da sustentabilidade, aquela relação de trabalho, a legislação atual referente ao trabalhador rural canavieiro e a realidade social do setor canavieiro são, neste estudo, abordadas. Nesta composição analisa-se a eficácia da aplicabilidade da convenção coletiva do setor canavieiro, através do estudo descritivo da expansão canavieira e a relação de trabalho com os cortadores de cana.

Resumo: Este trabalho apresenta o desenvolvimento tecnológico das usinas de açúcar e álcool do Estado de São Paulo. Primeiramente, faz-se uma abordagem dos fatores mais gerais que explicam a formação, expansão e consolidação da agroindústria canavieira no Estado de São Paulo. Assim, busca-se atingir o objetivo de discutir a modernização tecnológica das usinas paulistas em relação aos principais centros produtores internacionais, principalmente visando os sistemas de preparo e extração de caldo de cana. No início da década de 1970, as usinas paulistas utilizavam uma tecnologia ultrapassada em relação aos outros produtores açucareiros do mercado internacional. Diante dessa situação, a Copersucar implementou um Programa de Modernização visando a elevar a produtividade das usinas paulistas para níveis internacionais definidos pelas usinas dos países que apresentavam tecnologias mais avançadas, principalmente África do Sul, Austrália e Havaí. Isso foi possível através de um programa pelo qual a Copersucar selecionou e implantou as tecnologias mais desenvolvidas e mais apropriadas ao parque sucroalcooleiro nacional. Os estudos realizados permitem concluir que o dinamismo do setor sucroalcooleiro, implementado pela Copersucar, possibilitou a consolidação dos objetivos do Programa de Modernização das usinas de açúcar e álcool no Estado de São Paulo. Isso ocorreu devido à superação dos gargalos tecnológicos com o desenvolvimento de novas tecnologias, o que propiciou uma elevação dos níveis de produtividade das usinas paulistas aos patamares das usinas internacionais que utilizavam tecnologias mais desenvolvidas
Abstract: This work presents the technological development of the sugarcane and alcohol industrial sector in the State of Sao Paulo. It is emphasized the most important points of the technological modernization of the plants regarding the main international producers centers. The sugarcane businessman from the State Sao Paulo realized that if they did not improved the quality of the product and they continued to produce sugar with an outdated technology, they would be eliminated of the world market. Ahead of this situation, Copersucar - The Brazilian Sugarcane Research Institute implemented a Modemization Prograrn aiming to elevate the productivity of the plants from Sao Paulo into international levels defined by the plants of the countries that introduced more advanced technologies, mostly Southern Africa, Australia and Hawaii. That was possible through a Program by which Copersucar selected and implanted the most developed and appropriated technologies to the Brazilian sugarcane industrial park. The studies done allow us to the conclusion that the dynamic of the sugar cane industry, summed to the Copersucar efforts gave the consolidation of the Sugar Cane Industries Modernization Program at the State of Sao Paulo. That allowed to overcome the technologies limitations compared with the development of new technologies, what gave higher levels of productivity to the State of Sao Paulo sugar cane industries at a similar level of the international industry, which used more modems technologies

Resumo: O projeto aqui apresentado tem por tema a análise da evolução dos dois sistemas de extração de sacarose de cana-de-açúcar que têm sido utilizados na produção de açúcar e álcool no Brasil: o sistema de moendas e o de difusão. O primeiro é um sistema de separação física e de ampla utilização no mundo e no Brasil desde o período colonial. O sistema de difusão é um processo químico, desenvolvido no século XIX para extrair açúcar da beterraba e que foi adaptado e desde então vendo sendo empregado também no processamento da cana, em outros centros açucareiros do mundo. O objetivo desta tese é identificar e discutir as trajetórias desses dois sistemas, tendo como foco seus desenvolvimentos pela indústria ofertante de equipamentos para a fabricação de derivados da cana. Buscar compreender quais foram os fatores que levaram à utilização quase que exclusiva do sistema de moenda no Brasil até meados de 1980 e por que depois desse período, o sistema de extração por difusão vem sendo adotado por algumas firmas.

Der volle Inhalt der QuelleThis work proposes the specification and generation of standard experiments, models and interfaces for supporting to the process of production planning in the sugar cane industry, through simulation. Models embrace the agricultural and industrial sections of sugar cane plants, since the cane harvesting until the sugar and alcohol production. The system modelling, using commercial simulation softwares with flexibility of customization resources, seeks the generation of a simulation environment for performance and sensibility analyses. Standard models that compose this simulation environment allow simulations to be accomplished in 3 different scopes, from the plant, passing by the agricultural and industrial sections, and arriving at the level of the processes: cutting/loading, raw material reception, extraction, juice treatment, sugar production, alcohol production and stream generation. The user\'s interaction with the simulation environment through friendly interfaces, has the function of supplying the planner with an ease-to-use tool option, that makes possible the obtaining of useful information about the behavior and the interrelations among the principal variables that influence the system performance, allowing the choice of the most appropriate options in the search of improvements.

Der volle Inhalt der QuelleThe aim of the present work was to evaluate the refined sugar industryin Brazil and to identify its market behavior in the central region in Southern Brazil Accordingly, this study analyzed the influence of distinct levels of competition concerning price and entrance barriers on the market structure. Some exogenous factors, such as public regulation, sectorial organization, and strategies to set up costs, were also verified to determine the market sectors concentration. the theoretical model of two-stage game for industries intensive in exogenous sunk cost described by Sutton (1991) was used to determine the value of the set up costs for a single plant of minimum efficient scale (m.e.s). Data of the present study were compared to those reported by Sutton (1991), whose study focused on Europe, Japan, United States and Taiwan. The present work, however, focused on the central region in Southern Brazil. The ratio of the market concentration of the sugar-refining industry, as well as the ratio of its market size and exogenous sunk cost was calculated. The value of σ/S found for 2001 was 0.8407%, consistent with the values found for the countries analyzed by Sutton; furthermore, this result evidences the high index of set up costs and existence of barriers of entrance, suggesting that that the industry of refining sugar in Brazil was initiated with small and average commercial groups, with a regionally-concentrated sector. During the regulated period the industry was highly concentrated (by the 1980s the CR4 was about 80%). In the 1990s, there was a great entrance of new brands and consequently a decline in the leader brand (União). One of the reasons that such industry is highly concentrated is the huge sunk cost. Like the refined sugar industry analyzed in other countries, the Brazilian refined sugar industry presented, in 2003, high exogenous sunk cost in relation to the size market.

Der volle Inhalt der QuelleConsidered a sustainable fuel, ethanol produced from sugar cane, leaves a major liability during its production process, which has been deposited in the own sugar cane fields. The vinasse is generated, on average, in the proportion of 12 liters per liter of produced ethanol, is rich in different nutrients, which can be used for many purposes, such as the microalgae cultivation. This study evaluated in the first step the vinasse clarification by coagulation with cationic polymer, followed by crossflow microfiltration on a hollow fibers filter, which enable a reduction over 77% for apparent color, 99%for turbidity and 20% for COD, facilitating the use of this effluent for microalgae cultivation. In a second step, was evaluated the microalgae Chlorella vulgaris cultivation in bench scale and batch operation, in a medium prepared from the vinasse dilution in water from a deep well, getting an increase in the biomass production, measure in terms of chlorophyll-a, for a vinasse concentration below 7.5%, and an inoculum of approximately 106 individuals. These data allowed the microalgae cultivation in a continuous flow pilot-scale photobioreactor, which produced biomass that was used in the next stages of the study, for the evaluation of the biomass separation by dissolved air flotation. The first DAF tests carried out in bench scale and batch operation allowed to identify the optimum operation conditions, which were then evaluated in a continuous flow pilot scale dissolved air flotation unit (DAF). The DAF unit produced a sludge with a solid content greater than 2%, which was submitted to a final dewatering by centrifuge. The dewatering tests allowed to check that the use of the same polymer used for the clarification step, permit to obtain a more stable sludge when compared with the sludge without chemical add, and in the best cationic polymer dosage of 6 g.kg-1. The conclusion of this work has shown the possibility of use vinasse as a grow medium for microalgae cultivation, reducing one of impacts caused by ethanol production. In addition, it was possible to observe the potential of FAD, for biomass thickening, produced in photobioreactors.
