A decomposição de serapilheira é um processo fundamental para a ciclagem de nutrientes e a manutenção da fertilidade dos solos em florestas tropicais. Além disso, contribui com os fluxos de carbono para a atmosfera, sendo constantemente discutida no âmbito das mudanças climáticas globais. Dentre os fatores que influenciam na sua dinâmica, o local de origem das espécies vegetais, a qualidade nutricional da serapilheira e a comunidade decompositora do solo tem recebido destaque. Interações entre plantas e decompositores que resultam em uma maior decomposição no local de origem das espécies vegetais em relação a um local externo são denominadas \"home field advantage\" (HFA). O presente estudo teve como objetivos investigar a ocorrência do HFA, bem como a influência das interações entre o local de origem das espécies vegetais, os decompositores do solo e a qualidade nutricional do material vegetal na decomposição de serapilheira em áreas de Floresta Ombrófila Densa Atlântica de terras baixas e montana localizadas no litoral norte do estado de São Paulo. Para isso foi realizado um experimento de decomposição com permuta de material foliar entre as florestas de terras baixas e montana com duração de 250 dias, utilizando folhas senescentes da espécie Rustia formosa, proveniente da floresta de terras baixas, e Licania hoehnei, proveniente da floresta montana, e litter bags com diferentes aberturas de malha para controlar a inclusão exclusão da meso e macro fauna do solo. Também foram quantificadas as concentrações de nutrientes, compostos orgânicos e composição isotópica para determinação da qualidade inicial das serapilheiras e sua dinâmica durante a decomposição. As diferenças na qualidade inicial das espécies não causou diferenciação entre as suas taxas de decomposição. As taxas de decomposição foram semelhantes entre espécies e ambientes, não sendo verificada maior velocidade de decomposição associada com a interação entre as espécies e seus ambientes de origem, o que indica ausência de HFA. Além disso, não foi verificado efeito positivo da fauna do solo na decomposição. A dinâmica química dos detritos foliares evidenciou a imobilização de nitrogênio e acúmulo de lignina ao longo da decomposição, o que indica limitação na atividade microbiana por nitrogênio e baixa qualidade da serapilheira de Rustia formosa e Licania hoehnei. As variações nas concentrações de carbono, nitrogênio e fósforo influenciaram a dinâmica da decomposição ao longo do tempo. Esse estudo contribui para compreensão de como fatores importantes na decomposição interagem em ecossistemas tropicais, e aponta a importância da qualidade da serapilheira e disponibilidade de nutrientes no ambiente como direcionadores da decomposição. / Litter decomposition is a key process for nutrient cycling and maintenance of soil fertility in tropical forests, contributing to carbon fluxes to the atmosphere and being constantly discussed in the global climate change scenario. Among the main factors that control decomposition, the place of origin of species, litter quality and soil community are currently with great attention. Interactions between plants and decomposers that lead to a fast decomposition in the place of origin of species related to other sites and species are called home field advantage (HFA). The goal of this study was to investigate the occurrence of HFA, as well the influence of interactions between place of origin, soil decomposers and litter quality on the litter decomposition in areas of lowland and montane Atlantic forest located in the north coast of Sao Paulo state. For this it was performed an decomposition experiment with transplant of litter of Rustia Formosa, from lowland forest, and Licania hoehnei, from montane forest, between the two forests, with duration of 250 days, using litter bags with different mesh sizes to allow and exclude the access of meso and macro soil fauna. It was also quantified nutrient and organic compounds concentration to determine the initial litter quality and its dynamics during decomposition. The differences in initial litter quality between species did not cause differentiation in the decomposition rate. The decomposition rates were similar between species and ambient, with no faster decomposition associated with the interaction between species and its local places of origin, which indicates lack of HFA. Besides that, there was no positive effect of soil fauna on the decomposition. The chemical dynamics of litter pointed out nitrogen immobilization and lignin accumulation during decomposition, which indicates microbial limitation by nitrogen and low litter quality of Rustia Formosa and Licania hoehnei. The variations in carbon, nitrogen and lignin concentration influenced the dynamics of decomposition during the time. This study contributed to the comprehension of how important factors of decomposition can interact in tropical ecosystems, and pointed the importance of litter quality and nutrient availability of the ambient as drivers of decomposition.

Culinary tourism can contribute to the economic development of many rural communities. Creating competitive advantage for a rural community by establishing a culinary cluster requires a strategy designed to leverage the economic, cultural and environmental qualities of a place in an attractive setting and within reach of interested markets. Accordingly, culinary tourism development occurs in places with a ‘local milieu’ that possesses a concentration (spatial agglomeration) of local culinary-related products and services produced by their clustered production of a number of inter-connected firms and service providers. This can attract visitors, new residents and investments and lead to more sustainable economic outcomes that increase the quality of life of residents. To take full advantage of such possibilities, a strategy for partnership and collaboration among various stakeholders involved in culinary tourism is required. This study provides a conceptual foundation for culinary tourism as a part of the creative food economy through place branding. It analyzes the formation of culinary clusters in place-based rural community development. A culinary cluster results from innovation in the production and consumption of local food. The research began with a review and assessment of literature on culinary tourism, economic geography and business/management that led to the definition of concepts that were combined in the creation of a conceptual model based on modification of Porter’s (1990) clustering model. The model consists of ‘four interdependent determinants’ and ‘four facilitators’ that influence the creation of a culinary cluster, and that require attention in building a creative food economy and an environmentally friendly taste of a place as a brand. A ‘terroir’ contributes to the formation of a successful culinary cluster. Tourism and agriculture are leading sectors in this process. Four broad elements specified in the model (‘environmentally friendly movement’, ‘leadership’, ‘stakeholder collaboration’ and ‘communication & information flows’) are the challenges that must be met for the successful transformation of a ‘terroir’ into a creative and environmentally friendly tourism destination that provides the taste of a place and, eventually, contributes to the global green movement. The creation of the model is an important conceptual contribution of the study. The model is used in a variety of ways. First, it was used to guide the collection of information in field investigations of two selected case study sites in the province of Ontario, Canada (Savour Stratford and SAVOUR Muskoka). Second, it was used to structure the qualitative analyses in each case study. Third, it guided comparison of the case studies where it was also used as an evaluative tool to suggest what is working well and less well in the study clusters. It was also used prescriptively to suggest what elements require further attention to strengthen the performance of the clusters. The study focuses on the relatively new concepts of a creative food economy, environmentally friendly culinary tourism and place branding in the formation of a culinary cluster in place-based rural community development. These themes are obviously interrelated, but have not been explored together previously; and thus, the study provides conceptual coherence for addressing their relationships. The findings of the comparative case study suggest that the transformation of a ‘terroir’ into a taste of a place through place branding is based upon the identification of the strengths of a place through inventory of the culinary-related core resources, and the leading and supporting assets (e.g., hard factors of natural environment and soft factors of cultural heritage). Since these will be different from place to place, one should expect different outcomes as the comparative case study demonstrates. Success will depend upon the use of culinary-related resources, based on local things and knowledge, leadership, and stakeholder involvement through collaboration and partnership, to create a uniquely appealing identity and image (place brand). Thus, a synergistic relationship can be established between the primary sector (agriculture) and service sector (tourism) through innovative entrepreneurial activities. The study makes important contributions both conceptually and empirically by creating a model that addresses the conversion of ‘terroir’ into a creative and environmentally friendly tourism place, by demonstrating the utility of the model through application to two cases in a comparative format; and practically, by directing attention to items that need careful consideration if synergistic relationships are to be established between agriculture and tourism through the development of culinary clusters as part of place-based rural community development.

This thesis deals with two theories of international trade: the theory of comparative advantage, which is connected to the name David Ricardo and is dominating current trade theory, and Adam Smith’s theory of absolute advantage. Both theories are compared and their assumptions are scrutinised. The former theory is rejected on theoretical and empirical grounds in favour of the latter. On the basis of the theory of absolute advantage, developments of free international trade are examined, whereby the focus is on trade between industrial and underdeveloped countries. The main conclusions are that trade patterns are determined by absolute production cost advantages and that the gap between developed and poor countries is not reduced but rather increased by free trade. / Die vorliegende Publikation vergleicht die zwei zentralen Theorien des internationalen Freihandels: die Theorie der absoluten Kostenvorteile und die Theorie der komparativen Kostenvorteile. Dieser Vergleich führt zu dem Schluss, dass die Theorie der komparativen Kostenvorteile im Gegensatz zu der Theorie der absoluten Kostenvorteile auf unrealistischen und problematischen Annahmen beruht. Im Anschluss werden auf Grundlage der Theorie der absoluten Kostenvorteile zentrale Tendenzen in der Entwicklung des internationalen Handels herausgearbeitet. Im Mittelpunkt steht hierbei die Auswirkung von Freihandel auf entwickelte und unterentwickelte Länder. Die zentralen Schlussfolgerungen dieser Arbeit sind erstens, dass die Richtung des internationalen Handels nicht durch komparative Kostenvorteile, sondern durch absolute Kostenvorteile bestimmt wird und zweitens, dass Freihandel zwar vorteilhaft für unterentwickelte Länder sein kann, aber dass durch Freihandel die Unterschiede zwischen Industrieländern und Entwicklungsländern nicht verkleinert, sondern vergrößert werden.

The premise of this thesis is the need for research regarding the relation between social and natural values and the competitive advantage of a firm. The overall purpose of this thesis is to identify, describe and analyze how a firm can achieve competitive advantage from a transformation of social and natural values. In order to reach the purpose of this thesis a case study of Cascades Djupafors has been carried out which entailed personal interviews with a selection of the firm’s customers.  The theoretical framework involves a description of the creation of a sustainable business, process for creating societal advantage, the transformation of societal advantage to competitive advantage as well as an elaboration of the transformation process. The empirical study deals with the sustainable approach of Cascades Djupafors, their quest for a sustained business, their process from sustainability to competitiveness and an elaboration of Cascades Djupafors’ innovation developments. In the analysis the theoretical framework is related to the results of the empirical study. It is discussed and analysed how Cascades Djupafors can create social and natural values as well as economic values which is continued by a discussion regarding the creation of a sustainable business. In addition, the organizational learning process at Cascades Djupafors is elaborated with focus on capability development. It is concluded that a firm can transform social and natural values to competitive advantage by developing green capabilities to perform CSR activities that the customers value and thereby gain legitimacy. This can lead to a positive reputation which is linked to competitive advantage through the source of competitive advantage, i.e. green innovations. The competitive advantage allows a firm to set a premium price or increase its amount of sales which offers a possibility for increased financial outcome. At last, recommendations for further research within this field are presented together with specific managerial implications for Cascades Djupafors.

Abstract Prepainted steel is a new material developed after the year of 1960. It owns mainly advantages accompanied with corrosion resistance, long-life using, beautiful color and shape, easy utilization, and also keep the original strength of the steel. All these characteristics make it appropriate to be used on the wall, roof, and decoration of gym or any big construction and buildings. It can also be seen in the field of vehicles, many electrical appliances, computer shells, etc. Prepainted steel is the downstream product of steel enterprises. It comes manly from Galvanized steel coils, and a little portion of it from cold-rolled steel coils. There are now seven production companies in Taiwan at the annual production of 1.17 million tons. According to statistics, the local consumption of last year is 310,000 tons. It is fortunate that Mainland China has a mass need for it during these years. In 2002, Mainland china imported 1.02 million tons, and in 2003, 1.54 million tons. We need huge export to digest our production. My study case is an medium enterprise with the annual production 300,000 tons of prepainted steel, and without the production line of Galvanized steel with which prepainted steel can be done. This study mainly discusses how an enterprise construct its own competitive advantage and strategy through the outside environment analysis and management ability, then make the best choice of stragtegy which is appropriate to its business model before evaluating the strategy efficiency by theory. The first chapter is about its background and motive of the study, and contents and limits of the study are also included. The second chapter, from the theory basis of documents, try to understand the definition and relative meaning of following issues: vertical integration, strategic alliance, resources leveling and value chains¡Ketc. The third chapter of this study is about the marketing supply and demand situation of prepainted steel local and abroad, and it talks about on what kind of location that prepainted steel enterprise stands. This chapter also goes further introducing these important enterprises in Taiwan which earns prepainted steel, and make an analysis on enterprise environment and five forces analysis. The fourth chapter has an introduction of this study case and its cooperators and opponents. Moreover, a SWOT analysis of this study case is offered. Futher, there has a discussion on its strategy on competitive advantage ¡V strategic alliance, resources leveling,, value chains, vertical integration, business field¡Ketc. And a proof on the basic of the strategy and an evaluation on these strategic efficiency are made. At last, there will be a deep thinking on fast-changing environment and future strategies. We hope the ending can be used for the reference of this enterprise.

Various academic disciplines have attempted to explain the factors underpinning superior economic performance. Generally they neglect the realities of small states. The literature fails to clearly define a small state . Mainstream theories associate smallness with sub-optimality . Small states studies tend to be conditioned by a vulnerability complex. Yet, a good number of small states have an economic track record which is the envy of much larger states. This thesis adopts an interdisciplinary approach to investigate the theoretical explanations of superior economic performance, at both the state and firm level. Resource-advantage theory, which claims to be a general theory of competition, offers valuable insights in understanding the superior economic performance of small states. The field research follows Porter (1998) in studying the performance of particular industries to understand the competitiveness of nations. A qualitative, case study approach, involving both primary and secondary investigation, explores the performance of the pharmaceutical industry in Malta following the country s decision to join the EU. This work perceives a small state as an organisation with well-defined, but permeable, boundaries. This open system is characterised by both a lack of market power and a small population. Through the secondary field research a small number of higher-order resources, competencies and dynamic capabilities (RCDCs) are identified. The field research s findings affirm the relevance of these arch-RCDCs in creating competitive advantage for the pharmaceutical industry in Malta. It also elucidates the key role played by an external catalyst, foreign direct investment, to circumvent domestic limitations. The study finds that it is still relevant to study small states and that achieving a strategic fit between the resource base and international market opportunities is essential if small states are to enhance their market power and achieve a superior economic performance.

The differences in initial litter quality between species did not cause differentiation in the decomposition rate. The decomposition rates were similar between species and ambient, with no faster decomposition associated with the interaction between species and its local places of origin, which indicates lack of HFA. Besides that, there was no positive effect of soil fauna on the decomposition. The chemical dynamics of litter pointed out nitrogen immobilization and lignin accumulation during decomposition, which indicates microbial limitation by nitrogen and low litter quality of Rustia Formosa and Licania hoehnei. The variations in carbon, nitrogen and lignin concentration influenced the dynamics of decomposition during the time. This study contributed to the comprehension of how important factors of decomposition can interact in tropical ecosystems, and pointed the importance of litter quality and nutrient availability of the ambient as drivers of decomposition.

The field of study on coopetition has been given a growing emphasis in the recent years by researchers and business practice. Coopetition is a term integrating the notions of cooperation and competition happening as an intensive simultaneous process where actors seek to leverage the value created by other companies in their business network. These complex and paradoxical interactions are acknowledged as needing further research about the effects of coopetition and the different types of coopetitive interactions involved when firms coopete. The business network highlighted in the current study concerned the Swedish Cleantech industry. It offers an interesting ground as Sweden has been investing substantial amounts in environmental protection technologies. Moreover, SMEs in Sweden play an increasingly significant role in the national economy by their rapid technological development. Nonetheless, these SMEs battle to sustain opportunities and are facing many challenges such as lack of key resources, a limited market presence, and liabilities of newness. Thereby, collaboration is essential among Cleantech SMEs in order to overcome these challenges and sustain competitive advantages. This study sets out to fill this gap through the following objectives: by describing the cooperative and competitive activities happening of SMEs inside the Swedish Cleantech industry, by understanding how SMEs select their cooperative relationship with their competitors inside their business network, and by analyzing how coopetition can be implemented by SMEs as a strategy to develop sustainable competitive advantage. This research was conducted through a qualitative case study and semi-structured interviews of seven Swedish SMEs operating in the Cleantech industry. The findings underline that coopetition can be used as a matching strategy between the internal and the external environment of the firm. Further, before coopetition can lead to sustained competitive advantages, companies first need to develop societal advantages in the form of economic value, social value, and natural value.
