Sistemas de certificação florestal no setor de papel e celulose : influências no desempenho exportador

Fischer, Bruno Brandão January 2008 (has links)
A crescente preocupação mundial com o manejo dos recursos florestais tem exercido grande pressão nos ambientes extrativistas e industriais ligados à base produtiva silvícola. Em vista da dificuldade de se estabelecer quais empresas e produtores adotam padrões produtivos ambientalmente sustentáveis, o uso das certificações tem ganhado notoriedade, funcionando como mecanismo de sinalização de comportamento mercadologicamente valorizado. Este cenário representa empiricamente teorizações da Economia da Informação em um ambiente agroindustrial específico, apresentando ferramentas de emissão de sinais como potenciais redutores da assimetria de informação presente na estrutura econômica de comércio. Contudo, permanecem questionamentos sobre como este uso de certificações e conseqüente melhoria da disponibilidade informacional podem impactar sobre as firmas adotantes desta estratégia. Relacionando esta situação com elementos da Economia Industrial (abordagem Estrutura-Conduta-Desempenho) e caracterizando a sinalização como um elemento de Conduta, esta pesquisa se propõe a verificar empiricamente potenciais impactos desta estratégia de atuação no Desempenho resultante. Como objeto específico de estudo, elegeu-se, dentro da indústria silvícola brasileira, o setor de papel e celulose, dada a sua relevância econômica para o agronegócio brasileiro. O método de análise de desenvolve através de modelos econométricos que buscam estabelecer e mensurar relações de influência entre a evolução de adoção de certificações de manejo florestal sustentável no desempenho exportador agregado do setor para o período 1995- 2008 (dados mensais), visto que a prática de comércio internacional potencializa a disponibilidade assimétrica de informações. Os resultados encontrados são parcialmente conclusivos em direção à sustentação da hipótese de que o uso de certificações tem influências positivas sobre o desempenho de comércio exterior da indústria brasileira de papel e celulose. / World’s increasing concern regarding forest resources management has pressured the producers and industries connected to forestry activities. In face of the difficulty to differentiate agents’ productive patterns of behavior towards forests, the use of sustainable forest management certifications is becoming increasingly relevant, working as a supposedly market valued signaling device. This scenario represents empirically in a specific agroindustrial environment the theories developed in Information Economics, presenting signal emission tools as potential reducers of commercial information asymmetry. However, questions regarding how the use of these certifications and the consequent improvement of information availability impact on firms which adopt this strategy remain. Relating this situation with the elements of Industrial Economics (more specifically the Structure-Conduct-Performance approach) and defining the signaling behavior as a Conduct pattern, this research proposes an analysis of the possible impacts of this strategy in the resulting Performance. As object of study, the Brazilian Pulp & Paper (P&P) industry is chosen, given its economic importance for the country’s forest and agribusiness sectors. The methodology to develop this verification is based on econometric regression models, aiming to establish and measures influences between the sustainable forest management certifications implementation evolution in the aggregated exporting performance of the Brazilian P&P industry for the period 1995-2008 (monthly data), since the international trade is expected to rise the levels of information asymmetry and hence the value of signals. Results allow partial acceptance of the hypothesis that the use of certifications has positive influences on Brazilian P&P industry’s international trade performance.

Certification de programmes avec des effets calculatoires / Certification of programs with computational effects

Ekici, Burak 09 December 2015 (has links)
Dans cette thèse, nous visons à formaliser les effets calculatoires. En effet, les langages de programmation les plus utilisés impliquent différentes sortes d'effets de bord: changement d'état, exceptions, entrées / sorties, non-déterminisme, etc. Ils peuvent apporter facilité et flexibilité dans le processus de codage. Cependant, le problème est de prendre en compte les effets lorsque l'on veut prouver des propriétés de programmes. La principale difficulté dans ce genre de preuve de programmes est le décalage entre la syntaxe des opérations avec effets de bord et leur interprétation. Typiquement, un fragment de programme avec des arguments de type X qui retourne une valeur de type Y n'est pas interprété comme une fonction de X vers Y , à cause des effets.L'approche algébrique la plus connue pour ce problème permet une interprétation des programmes, y compris ceux comportant des effets, en utilisant des monades : l'interprétation est une fonction de X vers T (Y ) où T est une monade. Cette approche a été étendue aux théories de Lawvere et aux "gestionnaires algébriques" (algebraic handlers). Une autre approche, appelée logique décorée, fournit une sémantique équationnelle pour ces programmes. Nous spécialisons l'approche de la logique décorée pour les effets liés à l'état de la mémoire et à la gestion des exceptions en définissant la logique décorée pour les états (L_st) et la logique décorée pour les exceptions (L_exc), respectivement. Elles nous permettent de prouver des propriétés de programmes impliquant de tels effets. Ensuite, nous formalisons ces logiques en Coq et certifions les preuves associées. Ces logiques sont construites de manière à être correctes. En outre, nous introduisons une notion de complétude syntaxique relative d'une théorie dans une logique donnée par rapport à une sous-logique. Nous montrons que la théorie décorée pour les états globaux ainsi que deux théories décorées pour les exceptions sont relativement complets relativement à leur sous-logique pure. Non seulement nous pouvons utiliser le système développé pour prouver des programmes comportant des effets, mais également nous utilisons cette formalisation pour certifier les résultats de complétude obtenus. / In this thesis, we aim to formalize the effects of a computation. Indeed, most used programming languages involve different sorts of effects: state change, exceptions, input/output, non-determinism, etc. They may bring ease and flexibility to the coding process. However, the problem is to take into account the effects when proving the properties of programs. The major difficulty in such kind of reasoning is the mismatch between the syntax of operations with effects and their interpretation. Typically, a piece of program with arguments in X that returns a value in Y is not interpreted as a function from X to Y , due to the effects. The best-known algebraic approach to the problem interprets programs including effects with the use of monads: the interpretation is a function from X to T(Y) where T is a monad. This approach has been extendedto Lawvere theories and algebraic handlers. Another approach called, the decorated logic, provides a sort of equational semantics for reasoning about programs with effects. We specialize the approach of decorated logic to the state and the exceptions effects by defining the decorated logic for states (L_st) and the decorated logic for exceptions (L_exc), respectively. This enables us to prove properties of programs involving such effects. Then, we formalize these logics in Coq and certify the related proofs. These logics are built so as to be sound. In addition, we introduce a relative notion of syntactic completeness of a theory in a given logic with respect to a sublogic. We prove that the decorated theory for the global states as well as two decorated theories for exceptions are syntactically complete relatively to their pure sublogics. These proofs are certified in Coq as applications of ourgeneric frameworks.

La problématique de l'enseignement technique et professionnel moyen au Gabon / the problematic of technical and vocational middle education in Gaboon

Abdallah-Bindang Edou, Laïticia 11 June 2015 (has links)
La formation technique et professionnelle a souvent été considérée comme un facteur déterminant dans le processus de développement des forces productives des pays en quête de progrès, de croissance et de modernité tel que le Gabon. C'est dans cette logique qu'elle fut institutionnalisée et légitimée dans la loi 16/66 portant organisation générale de l'enseignement dans la République gabonaise. Mais depuis la tenue des Etats Généraux de l'Education et de la formation de 1983 au Gabon, le bilan diagnostic et les perspectives de l'enseignement technique et professionnel scolaire conduisent au désenchantement. Ses effets, pervers ne cessent d'être relevés dans les discours tenus par la société civile nationale et internationale. La parole n'étant jusqu'à ce jour pas donnée à ses principaux bénéficiaires que sont les élèves et les enseignants, c'est tout l'objectif de la présente étude. Avec eux, nous débattons des attributs sociaux de l'enseignement technique et professionnel scolaire, afin de répondre à la question de son attractivité, en dépit des discours peu élogieux prononcés à son égard. Nous examinons aussi les causes de l'inefficacité de l'enseignement technique et professionnel scolaire en interrogeant les conditions de scolarité des élèves, les certifications, les rendements scolaires et le vécu de carrière enseignante. / Technical and vocational studies have often been considered as a major element in the development process leading to progress, growth and modernity in countries such as Gaboon. lt is in such a state of mind that it was institutionalized and became legitimate with the law 10/66 which dealt with the general organization of education in the Republic of Gaboon. Since the EtatsGénétaux de l'Education Formation in 1983, the balance and perspectives of technical and vocational education led to a disillusioned view. lts biased effects are examined by the civil national and international society. Although, up to now the main benefactors such as the students and the teachers have not been allowed to speak up, it is thus the main object of our study. With their comments, on one hand, we shall view the main social features of the technical and vocational school in order to check its interest, notwithstanding the lack of favorable comments in public speeches. On the other hand we shall examine the causes of the lack of efficiency of the technical and vocational schools regarding the schooling, the process of graduation, the output and the insight of a teacher's career concerning his wages.

La certificación UTZ y su relación con el desempeño exportador de las empresas peruanas del sector cacao en los años 2018-2020

Mondragón Viera, Carla Alexsandra, Ledesma Munive, Marco Antonio 12 August 2021 (has links)
El cacao es uno de los productos agrícolas más importantes a nivel mundial y el Perú es uno de los principales países originarios del cultivo, posee el 60% de las variedades de cacao del mundo, según Sierra Exportadora (2021). En los últimos años, el país se ha mantenido en el puesto ocho de las exportaciones mundiales de cacao y su principal mercado ha sido la Unión Europea, según Sunat (2021) La presente investigación tiene como objetivo analizar si existe una relación entre la certificación UTZ y el desempeño exportador de las empresas peruanas del sector cacao en el periodo 2018 – 2020. Para ello, se ha considerado como dimensiones de la variable “Certificación UTZ” a las (i) Mejores prácticas agrícolas, (ii) condiciones de trabajo y (iii) cuidado del medio ambiente y en la segunda variable “Desempeño Exportador”, se optó por incluir a la (i) Intensidad de exportaciones, (ii) crecimiento de las ventas de exportación y (iii) volumen de ventas de exportación. En la investigación se empleó un enfoque mixto, con un tipo de diseño descriptivo-correlacional. Se realizaron entrevistas semiestructuradas a 11 expertos y se elaboró una encuesta validada por 3 expertos del sector y resuelta por 27 agentes de interés que representan el 74% de la población de la investigación, estas se procesaron en el programa SPSS bajo el análisis correlacional de Rho Spearman. Con ello, se validó que la certificación UTZ si se relaciona con el desempeño exportador de las empresas cacaoteras en el periodo 2018-2020. / Cocoa is one of the most important agricultural products worldwide and Peru is one of the main countries of origin of the crop, possessing 60% of the world's cocoa varieties, according to Sierra Exportadora (2021). In recent years, the country has remained in eighth place in world cocoa exports and its main market has been the European Union, according to Sunat (2021). The present research aims to analyze whether there is a relationship between UTZ certification and the export performance of Peruvian companies in the cocoa sector in the period 2018 - 2020. For this purpose, the dimensions of the variable "UTZ Certification" have been considered as (i) Best agricultural practices, (ii) working conditions and (iii) care for the environment and in the second variable "Export Performance", it was chosen to include (i) Export Intensity, (ii) export sales growth and (iii) export sales volume. The research used a mixed approach, with a descriptive-correlational design. Semi-structured interviews were conducted with 11 experts and a survey was prepared and validated by 3 industry experts and answered by 27 agents of interest representing 74% of the research population; these were processed in the SPSS program under the Rho Spearman correlational analysis. With this, it was validated that UTZ certification does relate to the export performance of cocoa companies in the period 2018-2020. / Tesis

The effects and limits of corporate gender equality standards : A feminist post-structuralist perspective

Albrechtsen, Lisette Frandsen January 2019 (has links)
Based on my research aim of covering a gap in the literature on corporate gender equality standards, I research the effects and limits of corporate gender equality standards through a feminist poststructuralist perspective using the case study of the EDGE standard. Based on a qualitative research design, I build an analytical framework on Carol Bacchi’s ‘What’s the Problem Represented to be’ (WPR) approach to analyze the material in form of the five assessment areas of the EDGE standard. Based on the feminist post-structuralist perspective, my analysis showcases that the EDGE standard as a governance tool is not guided by tangible ‘problems' that exist ‘out there’ but rather through the representation of ‘problems’ as framed in the EDGE standard. The EDGE standard is thus a productive force that give shape and meaning to various problems of gender inequality which at the same time, the standard is also meant to address. I conclude that in some cases, the EDGE standard can have positive effects. However, the lack of an intersectional approach limits the EDGE standard too. This thesis contributes to the field by closing a research gap in the academic literature on the effects and limits of corporate gender equality standards analyzed through a feminist poststructuralist lens. / Jeg undersøger virkningerne og begrænsningerne af ligestillingsstandarder i organisationer gennem en feministisk poststrukturalistisk analyse af organisationsstandarden ’EDGE’. Baseret på mit mål om at afdække manglende forskning af ligestillingsstandarder anvender jeg et kvalitativt forskningsdesign som bygger på Carol Bacchis 'What’s The Problem Represented To Be’ for at analysere materialet i form af de fem vurderingsområder i EDGE-standarden. Med baggrund i det feministisk post-strukturalistiske perspektiv viser analysen, at EDGE-standarden som et styringsværktøj ikke styres af konkrete 'problemer', der eksisterer 'derude', men snarere styres gennem repræsentationen af ​​'problemer' som de indrammes og konstrueres i EDGE-standarden. EDGE-standarden er således en produktiv kraft, der giver form og mening til forskellige problemer inden for diskrimination og ligestilling mellem kønnene samtidigt med at standarden også er udviklet til at tackle disse ’problemer’. Jeg konkluderer, at EDGE-standarden i nogle tilfælde kan have positive effekter, men manglen på en tværgående og intersektionelle tilgange til EDGE’s fem vurderingsområder begrænser imidlertid også EDGE-standarden. Dette speciale bidrager til feltet inden for ligestilling og organisationsstandarder ved at afdække virkningerne og grænsningerne af erhvervslivets ligestillingsstandarder analyseret gennem en feministisk poststrukturalistisk perspektiv.

Decision making when investing in sustainable technology within the building sector

Nilsson, Henrik, Nordlund, Henrik January 2012 (has links)
The housing and service sector in Sweden are estimated to be responsible for 40 % of the total primary energy usage (Energimyndigheten, 2011). There exist a lot of inventions that have the possibility to greatly improve the environmental performance of a building´s LCA (Life Cycle Assessment) (Swentec, 2012) (Rutqvist, 2008). In order to achieve implementation of new innovative sustainable installations in buildings it is important to understand the process during the investment decision. Understanding the decision making process used in practise, is the first step towards creating a strategy for how to get a new technology implemented. By conducting a survey including both contractors and developers in Sweden an overview of the building sectors standpoint on environmental sustainability is achieved. In order to refine the information and achieve a more detailed picture of the issue the survey was followed up by In-depth interviews.The findings show that valuation techniques are varying a lot between companies but surprisingly many of the companies do use inferior methods such as pay back-time for investment calculations. Overall in the construction business technical and economic risk aspects are not being valued explicitly but rather through the use of product ratings and brand promise of well-known suppliers. Negative externalities are not being included in the calculations and the valuation of intangibles is not done explicitly but rather seen as implicitly derived from the cost and value of sustainability certifications.

Propuesta de guía para la aplicación de técnicas de uso eficiente y ahorro del agua con base en criterios de sostenibilidad de certificaciones internacionales (LEED, BREEAM y EDGE) en nuevas viviendas multifamiliares de la provincia de Cusco / Proposal guide for the application of techniques of efficient use and water saving based on sustainability criteria of international certifications (LEED, BREEAM and EDGE) in new multifamily homes in the province of Cusco

Alarcón Chávez, Laleska Gloria, Astorima Contreras, Cesar Andre 18 September 2021 (has links)
En la provincia del Cusco, se registra un aumento constante en la construcción de viviendas multifamiliares debido al crecimiento poblacional y económico en la modernización, transformación y desarrollo del lugar. Sin embargo, se ha relegado la implementación de técnicas sostenibles que puedan ayudar a contener los principales problemas ambientales. Entre ellos, el elevado estrés hídrico existente. En este contexto, se presenta la posibilidad de mejorar el uso del recurso hídrico mediante la implementación de tecnologías que se basen en la disminución del consumo de agua en las nuevas viviendas multifamiliares. Para esto, es necesario recurrir a la información que nos brindan las certificaciones internacionales que existen actualmente en el país, ya que el uso de dichas certificaciones garantiza la sostenibilidad en los proyectos, estas certificaciones son LEED, BREEAM Y EDGE. La propuesta busca asegurar el consumo eficiente y ahorro de agua en las nuevas viviendas multifamiliares de la provincia de Cusco, mediante la implementación de tecnologías que se encuentran en la categoría de agua de las certificaciones internacionales LEED, BREEAM Y EDGE. En este sentido la investigación desarrolla una propuesta que consiste en la implementación de una guía que contiene una variedad de sistemas de ahorro de agua en un proyecto multifamiliar convencional en la provincia de Cusco, se verificó si la propuesta es factible mediante un estudio de viabilidad técnica y económica del edificio con los nuevos sistemas implementados. Los resultados obtenidos demuestran un porcentaje de ahorro del 60% en reducción del consumo del agua en la etapa operativa del edificio con la aplicación de la guía propuesta. / In the province of Cusco, there is a constant increase in the construction of multifamily housing due to the population and economic growth in the modernisation, transformation and development of the place. However, the implementation of sustainable techniques that can help contain major environmental problems has been relegated. Among them, the high water stress that exists. In this context, the possibility of improving the use of water resources is presented by the implementation of technologies based on the reduction of water consumption in new multi-family housing. To do this, it is necessary to use the information provided by the international certifications that currently exist in the country, since the use of these certifications guarantees the sustainability in the projects, these certifications are LEED, BREEAM and EDGE. The proposal seeks to ensure the efficient consumption and saving of water in the new multifamily homes in the province of Cusco, through In this sense the research develops a proposal consisting of the implementation of a guide that contains a variety of water saving systems in a conventional multifamily project in the province of Cusco, it was verified whether the proposal is feasible by a study of the technical and economic feasibility of the building with the new systems implemented.The results obtained show a 60% savings percentage in reducing water consumption at the building operational stage with the application of the proposed guide. / Tesis
