Probiotic in feeding of juvenile matrinxã (Brycon amazonicus): economic viability

Objetivou-se analisar a viabilidade econômica do uso do probiótico Bacillus subtilis na alimentação de matrinxã Brycon amazonicus, em tanques-rede. O experimento foi conduzido no Polo Regional do Vale do Ribeira, no município de Pariquera-Açu, São Paulo, Brasil, entre fevereiro e julho de 2009. Foram avaliados 960 peixes juvenis, divididos em 12 tanques-rede de 2,7 m³ (1,5 x 1,5 x 1,2 m) em uma área total de 600 m², com profundidade média de 1,50 m. Os testes foram conduzidos com um tratamento testemunha (T1), duas doses de probiótico (T2 = 5 g e T3 = 10 g kg-1 de ração) e quatro repetições. Os resultados mostraram que o T2 proporcionou melhor desempenho zootécnico e econômico da matrinxã na fase de engorda no sistema intensivo de criação.

Financial media, globalisation, and China’s economic integration: comparing narrative construction of the Economist and Caijing

In June 2015, legal frameworks of the Asian Infrastructural Investment Bank were signed by its 57 founding members. Proposed and initiated by China, this multilateral development bank is considered to be an Asian counterpart to break the monopoly of the World Bank and the International Monetary Fund. In October 2015, China’s Central Bank announced a benchmark interest rate cut to combat the economic slowdown. The easing policy coincides with the European Central Bank’s announcement of doubts over US Fed’s commitment to raise interest rates. Global stock markets responded positively to China’s move, with the exception of the indexes from Wall Street (Bland, 2015; Elliott, 2015). In the meantime, China’s ‘One Belt, One Road’ (or New Silk Road Economic Belt) became atopic of discourse in relation to its growing global economy, as China pledged $40 billion to trade and infrastructure projects (Bermingham, 2015). The foreign policy aims to reinforce the economic belt from western China through Central Asia towards Europe, as well as to construct maritime trading routes from coastal China through the South China Sea (Summers, 2015). In 2012, The Economist launched a new China section, to reveal the complexity of the‘meteoric rise’ of China. John Micklethwait, who was then the chief editor of the magazine, said that China’s emergence as a global power justified giving it a section of its own(Roush, 2012). In July 2015, Hu Shuli, the former chief editor of Caijing, announced the launch of a think tank and financial data service division called Caixin Insight Group, which encompasses the new Caixin China Purchasing Managers Index (PMI). Incooperation with with Markit Group, a principal global provider of PMI, the index soon became a widely cited economic indicator. One anecdote from November’s Caixin shows how much has changed: in a high-profile dialogue between Hu Shuli and Kevin Rudd, Hu insisted on asking questions in English; interestingly, the former Prime Minister of Australia insisted on replying in Chinese. These recent developments point to one thing: the economic ascent of China and its increasing influence on the power play between economics and politics in world markets. China has begun to take a more active role in rule making and enforcement under neoliberal frameworks. However, due to the country’s size and the scale of its economy in comparison to other countries, China’s version of globalisation has unique characteristics. The ‘Capitalist-socialist’ paradox is vital to China’s market-oriented transformation. In order to comprehend how such unique features are articulated and understood, there are several questions worth investigating in the realms of media and communication studies,such as how China’s neoliberal restructuring is portrayed and perceived by different types of interested parties, and how these portrayals are de-contextualised and re-contextualised in global or Anglo-American narratives. Therefore, based on a combination of the themes of globalisation, financial media and China’s economic integration, this thesis attempts to explore how financial media construct the narratives of China’s economic globalisation through the deployment of comparative and multi-disciplinary approaches. Two outstanding elite financial magazines, Britain’s The Economist, which has a global readership and influence, and Caijing, China’s leading financial magazine, are chosen as case studies to exemplify differing media discourses, representing, respectively, Anglo-American and Chinese socio-economic and political backgrounds, as well as their own journalistic cultures. This thesis tries to answer the questions of how and why China’s neoliberal restructuring is constructed from a globally-oriented perspective. The construction primarily involves people who are influential in business and policymaking. Hence, the analysis falls into the paradigm of elite-elite communication, which is an important but relatively less developed perspective in studying China and its globalisation. The comparing of characteristics of narrative construction are the result of the textual analysis of articles published over a ten-year period (mid-1998 to mid-2008). The corpus of samples come from the two media outlets’ coverage of three selected events:China becoming a member of the World Trade Organization, its outward direct investment, and the listing of stocks of Chinese companies in overseas exchanges, which are mutually exclusive in sample collection and collectively exhaustive in the inclusion of articles regarding China’s economic globalisation. The findings help to understand that, despite language, socio-economic and political differences, elite financial media with globally-oriented readerships share similar methods of and approaches to agenda setting, the evaluation of news prominence, the selection of frame, and the advocacy of deeply rooted neoliberal ideas. The comparison of their distinctive features reflects the different phases of building up the sense of identity in their readers as global elites, as well as the different economic interests that are aligned with the corresponding readerships. However, textual analysis is only relevant in terms of exploring how the narratives are constructed and the elements they include; textual analysis alone prevents us from seeing the obstacles and the constrains of the journalistic practices of construction. Therefore, this thesis provides a brief discussion of interviews with practitioners from the two media, in order to understand how similar or different narratives are manifested and perceived, how the concept of neoliberalism deviates from and is justified in the Chinese context, and how and for what purpose deviations arise from Western to Chinese contexts. The thesis also contributes to defining financial media in the domain of elite communication. The relevant and closely interlocking concepts of globalisation, elitism and neoliberalism are discussed, and are used as a theoretical bedrock in the analysis of texts and contexts. It is important to address the agenda-setting and ideological role of elite financial media, because of its narrative formula of infusing business facts with opinions,which is important in constructing the global elite identity as well as influencing neoliberal policy-making. On the other hand, ‘journalistic professionalism’ has been redefined, in that the elite identity is shared by the content producer, reader and the actors in the news stories emerging from the much-compressed news cycle. The professionalism of elite financial media requires a dual definition, that of being professional in the understanding of business facts and statistics, and that of being professional in the making sense of stories by deploying economic logic.

Why Economists Reject Long-Term Fisheries Management Plans?

Most fisheries agencies conduct biological and economic assessments independently. This independent conduct may lead to situations in which economists reject management plans proposed by biologists. The objective of this study is to show how to find optimal strategies that may satisfy biologists and economists' conditions. In particular we characterize optimal fishing trajectories that maximize the present value of a discounted economic indicator taking into account the age-structure of the population as in stock assessment methodologies. This approach is applied to the Northern Stock of Hake. Our main empirical findings are: i) Optimal policy may be far away from any of the classical scenarios proposed by biologists, ii) The more the future is discounted, the higher the likelihood of finding contradictions among scenarios proposed by biologists and conclusions from economic analysis, iii) Optimal management reduces the risk of the stock falling under precautionary levels, especially if the future is not discounted to much, and iv) Optimal stationary fishing rate may be very different depending on the economic indicator used as reference.

Metodologia de avaliação da sustentabilidade económica de edifícios com base no ciclo de vida

O Comité Técnico CEN/TC 350 “Sustainability of construction works” elaborou um conjunto de normas que propõem um sistema de avaliação do contributo da construção para o desenvolvimento sustentável, nomeadamente através da avaliação dos seus desempenhos ambiental, social e económico, baseado numa abordagem de ciclo de vida. Os sistemas de avaliação da sustentabilidade de edifícios têm um papel importante em todas as fases do ciclo de vida (anterior à utilização, utilização e fim de vida) de um edifício que se pretenda sustentável, pois agilizam a integração entre os aspetos ambientais, sociais e económicos com outros critérios de decisão. Esta dissertação tem como objetivo apresentar uma metodologia inovadora de avaliação sistemática do desempenho económico de edifícios dentro do conceito sustentabilidade, com base na análise do ciclo de vida, conforme estabelecido na EN 16627:2015, que descreve o processo de tomada de decisão e documentação da avaliação do desempenho económico de edifícios dentro do conceito da avaliação da sustentabilidade, com base na análise de ciclo de vida (ACV). A metodologia, intitulada “Methodology of Assessment of Economic Performance - Residential Buildings – MAEP-RB”, permite a avaliação do desempenho e da sustentabilidade económica de edifícios na fase anterior à utilização do ciclo de vida. A metodologia segue o princípio de modularidade, onde os aspetos e impactes que influenciam o desempenho económico do edifício durante as fases do seu ciclo de vida, são atribuídos aos indicadores de cada módulo do ciclo de vida em que eles ocorrem dentro da respectiva etapa. Faz parte integrante desta metodologia uma base de dados contendo um modelo de custos na construção baseado na subdivisão do edifício em sistemas, subsistemas, elementos, componentes e subcomponentes, em que este último se encontra ao nível dos recursos. Os resultados da avaliação do desempenho económico e da sustentabilidade económica são desagregados em vários níveis, ou seja, ao nível da fase anterior à utilização do ciclo de vida do edifício, de cada etapa, de cada módulo e de cada indicador económico. A MAEP-RB avalia simultaneamente o desempenho económico e a sustentabilidade económica de edifícios sendo o resultado do desempenho económico expresso em unidade monetária e o da sustentabilidade comunicado por um Índice de Sustentabilidade Económica (A+, A, B, C, D, E).

Desigualdades sociais em saúde nos idosos : um retrato para Portugal

RESUMO - Contexto: As desigualdades sociais em saúde são uma questão central de justiça social. No contexto de forte envelhecimento populacional em Portugal, as desigualdades nos idosos representam um desafio crucial para o futuro, sobre as quais existe pouca evidência. Este estudo pretende investigar a existência de desigualdades socioeconómicas em saúde nos idosos, em Portugal. Metodologia: Foram utilizados os dados para Portugal, da quarta vaga do Survey of Health, Ageing and Retirement in Europe. O estudo engloba 2017 indivíduos com 50 ou mais anos. Foram utilizados quatro indicadores de saúde: problemas de saúde, saúde auto-reportada, doenças de longa duração e atividade limitada. Foi utilizado o nível de educação como indicador socioeconómico. As desigualdades socioeconómicas foram avaliadas através de regressões logísticas multivariadas. Resultados: Existem desigualdades socioeconómicas em saúde nos idosos favoráveis aos mais educados. Os indivíduos com menor educação estão em maior risco de reportar má saúde (OR=5,5); maior risco em ter problemas de saúde, existindo um gradiente social na Hipertensão Arterial (OR=2,4) e na Artrite (OR=7,0); maior risco de doenças de longa duração (OR=1,6) e maior risco de limitação nas atividades diárias (OR=5,1). As desigualdades socioeconómicas diminuem com a idade. Conclusão: De forma a melhorar a saúde e reduzir as desigualdades socioeconómicas em saúde nos idosos, os resultados apontam para a necessidade de implementar medidas no âmbito dos problemas de saúde em que existe um gradiente social, melhorar o nível de educação da população geral e implementar medidas de educação para a saúde, aumentando a literacia em saúde nos idosos mais jovens.

Le Brésil et le MERCOSUR : étude des stratégies de recherche de l'autonomie et de la puissance

Ce mémoire a pour objet de recherche le Marché commun du Sud (MERCOSUR) et le Brésil. La problématique est de comprendre pourquoi les États membres du MERCOSUR ne sont pas, à ce jour, parvenus à la création d’un marché commun dans le Cône Sud. Pour ce faire, nous pensons qu’en plus des causes généralement admises dans la littérature (asymétries, divergences d’intérêts et obstacles au niveau économique), il faut davantage mettre l’accent sur l’augmentation de la puissance du Brésil et les stratégies de recherche de l’autonomie. Les hypothèses avancées sont les suivantes : (1) la stratégie de recherche de l’autonomie par la participation a favorisée la création ainsi que l’approfondissement du MERCOSUR durant ses premières années d’existence; (2) la montée en puissance du Brésil et la stratégie de recherche de l’autonomie par la diversification qui en découle ont réduit l’importance du MERCOSUR pour le Brésil et miné l’approfondissement de cette institution d’intégration économique. Pour ce faire, nous analyserons en parallèle les différentes stratégies de recherche de l’autonomie ainsi que l’évolution du MERCOSUR. Nous utiliserons le PIB comme principal indicateur économique afin de témoigner de la montée en puissance du Brésil entre 1990 et 2012.

Custo de produção do maracujá-amarelo (Passiflora edulis)

Objetivou-se analisar economicamente a cultura do maracujá-amarelo (Passiflora edulis) na região de Marília-SP, safra de 2010/2011. Foram utilizadas estruturas do custo operacional efetivo e custo operacional total referente à fase de implantação e condução da lavoura por unidade de área e cinco indicadores de rentabilidade. Identificou-se um custo total de produção de R$ 37.751,67 por hectare ou R$ 1,89 por quilo da fruta. Os itens do custo operacional efetivo que mais oneraram o sistema de produção corresponderam às operações de máquinas (31,1%) e mão de obra (23,5%). Os indicadores de rentabilidade mostraram-se desfavoráveis para o sistema produtivo analisado, em decorrência, principalmente, do alto preço dos insumos e práticas para controle de doenças. Há necessidade de adequações técnicas relacionadas com o manejo fitossanitário da cultura para a redução do custo total de produção de modo a tornar a atividade rentável.

Sistema de simulación de escenarios de ciclos avanzados de combustible nuclear en transición = Simulation system for advanced fuel cycle transition scenarios

El estudio de los ciclos del combustible nuclear requieren de herramientas computacionales o "códigos" versátiles para dar respuestas al problema multicriterio de evaluar los actuales ciclos o las capacidades de las diferentes estrategias y escenarios con potencial de desarrollo en a nivel nacional, regional o mundial. Por otra parte, la introducción de nuevas tecnologías para reactores y procesos industriales hace que los códigos existentes requieran nuevas capacidades para evaluar la transición del estado actual del ciclo del combustible hacia otros más avanzados y sostenibles. Brevemente, esta tesis se centra en dar respuesta a las principales preguntas, en términos económicos y de recursos, al análisis de escenarios de ciclos de combustible, en particular, para el análisis de los diferentes escenarios del ciclo del combustible de relativa importancia para España y Europa. Para alcanzar este objetivo ha sido necesaria la actualización y el desarrollo de nuevas capacidades del código TR_EVOL (Transition Evolution code). Este trabajo ha sido desarrollado en el Programa de Innovación Nuclear del CIEMAT desde el año 2010. Esta tesis se divide en 6 capítulos. El primer capítulo ofrece una visión general del ciclo de combustible nuclear, sus principales etapas y los diferentes tipos utilizados en la actualidad o en desarrollo para el futuro. Además, se describen las fuentes de material nuclear que podrían ser utilizadas como combustible (uranio y otros). También se puntualizan brevemente una serie de herramientas desarrolladas para el estudio de estos ciclos de combustible nuclear. El capítulo 2 está dirigido a dar una idea básica acerca de los costes involucrados en la generación de electricidad mediante energía nuclear. Aquí se presentan una clasificación de estos costos y sus estimaciones, obtenidas en la bibliografía, y que han sido evaluadas y utilizadas en esta tesis. Se ha incluido también una breve descripción del principal indicador económico utilizado en esta tesis, el “coste nivelado de la electricidad”. El capítulo 3 se centra en la descripción del código de simulación desarrollado para el estudio del ciclo del combustible nuclear, TR_EVOL, que ha sido diseñado para evaluar diferentes opciones de ciclos de combustibles. En particular, pueden ser evaluados las diversos reactores con, posiblemente, diferentes tipos de combustibles y sus instalaciones del ciclo asociadas. El módulo de evaluaciones económica de TR_EVOL ofrece el coste nivelado de la electricidad haciendo uso de las cuatro fuentes principales de información económica y de la salida del balance de masas obtenido de la simulación del ciclo en TR_EVOL. Por otra parte, la estimación de las incertidumbres en los costes también puede ser efectuada por el código. Se ha efectuado un proceso de comprobación cruzada de las funcionalidades del código y se descrine en el Capítulo 4. El proceso se ha aplicado en cuatro etapas de acuerdo con las características más importantes de TR_EVOL, balance de masas, composición isotópica y análisis económico. Así, la primera etapa ha consistido en el balance masas del ciclo de combustible nuclear actual de España. La segunda etapa se ha centrado en la comprobación de la composición isotópica del flujo de masas mediante el la simulación del ciclo del combustible definido en el proyecto CP-ESFR UE. Las dos últimas etapas han tenido como objetivo validar el módulo económico. De este modo, en la tercera etapa han sido evaluados los tres principales costes (financieros, operación y mantenimiento y de combustible) y comparados con los obtenidos por el proyecto ARCAS, omitiendo los costes del fin del ciclo o Back-end, los que han sido evaluado solo en la cuarta etapa, haciendo uso de costes unitarios y parámetros obtenidos a partir de la bibliografía. En el capítulo 5 se analizan dos grupos de opciones del ciclo del combustible nuclear de relevante importancia, en términos económicos y de recursos, para España y Europa. Para el caso español, se han simulado dos grupos de escenarios del ciclo del combustible, incluyendo estrategias de reproceso y extensión de vida de los reactores. Este análisis se ha centrado en explorar las ventajas y desventajas de reprocesado de combustible irradiado en un país con una “relativa” pequeña cantidad de reactores nucleares. Para el grupo de Europa se han tratado cuatro escenarios, incluyendo opciones de transmutación. Los escenarios incluyen los reactores actuales utilizando la tecnología reactor de agua ligera y ciclo abierto, un reemplazo total de los reactores actuales con reactores rápidos que queman combustible U-Pu MOX y dos escenarios del ciclo del combustible con transmutación de actínidos minoritarios en una parte de los reactores rápidos o en sistemas impulsados por aceleradores dedicados a transmutación. Finalmente, el capítulo 6 da las principales conclusiones obtenidas de esta tesis y los trabajos futuros previstos en el campo del análisis de ciclos de combustible nuclear. ABSTRACT The study of the nuclear fuel cycle requires versatile computational tools or “codes” to provide answers to the multicriteria problem of assessing current nuclear fuel cycles or the capabilities of different strategies and scenarios with potential development in a country, region or at world level. Moreover, the introduction of new technologies for reactors and industrial processes makes the existing codes to require new capabilities to assess the transition from current status of the fuel cycle to the more advanced and sustainable ones. Briefly, this thesis is focused in providing answers to the main questions about resources and economics in fuel cycle scenario analyses, in particular for the analysis of different fuel cycle scenarios with relative importance for Spain and Europe. The upgrade and development of new capabilities of the TR_EVOL code (Transition Evolution code) has been necessary to achieve this goal. This work has been developed in the Nuclear Innovation Program at CIEMAT since year 2010. This thesis is divided in 6 chapters. The first one gives an overview of the nuclear fuel cycle, its main stages and types currently used or in development for the future. Besides the sources of nuclear material that could be used as fuel (uranium and others) are also viewed here. A number of tools developed for the study of these nuclear fuel cycles are also briefly described in this chapter. Chapter 2 is aimed to give a basic idea about the cost involved in the electricity generation by means of the nuclear energy. The main classification of these costs and their estimations given by bibliography, which have been evaluated in this thesis, are presented. A brief description of the Levelized Cost of Electricity, the principal economic indicator used in this thesis, has been also included. Chapter 3 is focused on the description of the simulation tool TR_EVOL developed for the study of the nuclear fuel cycle. TR_EVOL has been designed to evaluate different options for the fuel cycle scenario. In particular, diverse nuclear power plants, having possibly different types of fuels and the associated fuel cycle facilities can be assessed. The TR_EVOL module for economic assessments provides the Levelized Cost of Electricity making use of the TR_EVOL mass balance output and four main sources of economic information. Furthermore, uncertainties assessment can be also carried out by the code. A cross checking process of the performance of the code has been accomplished and it is shown in Chapter 4. The process has been applied in four stages according to the most important features of TR_EVOL. Thus, the first stage has involved the mass balance of the current Spanish nuclear fuel cycle. The second stage has been focused in the isotopic composition of the mass flow using the fuel cycle defined in the EU project CP-ESFR. The last two stages have been aimed to validate the economic module. In the third stage, the main three generation costs (financial cost, O&M and fuel cost) have been assessed and compared to those obtained by ARCAS project, omitting the back-end costs. This last cost has been evaluated alone in the fourth stage, making use of some unit cost and parameters obtained from the bibliography. In Chapter 5 two groups of nuclear fuel cycle options with relevant importance for Spain and Europe are analyzed in economic and resources terms. For the Spanish case, two groups of fuel cycle scenarios have been simulated including reprocessing strategies and life extension of the current reactor fleet. This analysis has been focused on exploring the advantages and disadvantages of spent fuel reprocessing in a country with relatively small amount of nuclear power plants. For the European group, four fuel cycle scenarios involving transmutation options have been addressed. Scenarios include the current fleet using Light Water Reactor technology and open fuel cycle, a full replacement of the initial fleet with Fast Reactors burning U-Pu MOX fuel and two fuel cycle scenarios with Minor Actinide transmutation in a fraction of the FR fleet or in dedicated Accelerator Driven Systems. Finally, Chapter 6 gives the main conclusions obtained from this thesis and the future work foreseen in the field of nuclear fuel cycle analysis.

Les petites pêches côtières et estuariennes Françaises du sud du golfe de Gascogne. Typologie des flottilles et approche socio-économique et commerciale

The European contract PECOSUDE (Small inshore fisheries of the south of Europe) accepted in 2000 for 2 years concerns French, Spanish and Portuguese partners. The aim is to assess the inshore and estuarine fisheries from Loire estuary to Portugal. Three levels of study are considered : fisheries (data 1999), socioeconomy and marketing (data 1999 or 2000). Exploitation in the 12 miles area for France and on continental shelf for northern Spain and Portugal (within 1000 m depth), as well as the fishing period lower than 96 hours was determined as the definition of this fishery for the study. Socioeconomic analyses are made only on boats smaller than 15 m. The fisheries part analyses the activity of the fishing vessels taking into account gears used, landed species, areas and fishing seasons. Within the 39 harbours of the south Bay of Biscay 1 799 coastal or estuarine vessels with 3 580 fishermen are located. Statics gears are predominant, and more than half of the vessels are polyvalent (using several gears). In 1999, landings were 20 6441 weight for 84 M¿ value. The fishing activity of these boats was also analysed by typology of the fleet, based on fishing gears and/or species landed. These characterisations allowed the application of stratified sampling for the implementation of socioeconomic investigations. The analysis of the information received from the fishermen allow to describe the production factors, to estimate their costs, as well as the turnover, the richness creation and the efficiency of the production means. The capital value of the south Bay of Biscay " ship " is established about 94 k¿, the average turnover amount to 83 k¿ and the average rate of added value to 70%. Products commercialisation vary from component to component, the importance of the sells in auction places depends on the landed species. Some valuable species are directly sold to particular

The missing link: using the NBER recession indicator to construct coincident and leading indices economic activity

We use the information content in the decisions of the NBER Business Cycle Dating Committee to construct coincident and leading indices of economic activity for the United States. We identify the coincident index by assuming that the coincident variables have a common cycle with the unobserved state of the economy, and that the NBER business cycle dates signify the turning points in the unobserved state. This model allows us to estimate our coincident index as a linear combination of the coincident series. We establish that our index performs better than other currently popular coincident indices of economic activity.
