Insostenibilidad del pago de la deuda externa desde el punto de vista económico, social y ambiental (Tema Central)

La autora sostiene que, dadas las condiciones usualmente impuestas por los países industrializados acreedores, el pago de la deuda externa es inviable para el Ecuador. Si se consideran aspectos económicos, sociales yambientales, se puede apreciar que el actual servicio de la deuda genera una balanza de pagos insostenible, deterioro de la capacidad productiva local. aumento de la precariedad del mercado laboral, incremento de la extrema pobreza y una presión insoportable sobre los recursos naturales. Mediante un análisis de ciertos indicadores selectos, la autora establece las relaciones existentes entre el ajuste para servir a la deuda, el deterioro de las condiciones de vida, el impacto en la agricultura y los recursos naturales y la dinámica de los procesos migratorios.

Impacts of plant-based foods in ancestral hominin diets on the metabolism and function of gut microbiota in vitro

Ancestral human populations had diets containing more indigestible plant material than present-day diets in industrialized countries. One hypothesis for the rise in prevalence of obesity is that physiological mechanisms for controlling appetite evolved to match a diet with plant fiber content higher than that of present-day diets. We investigated how diet affects gut microbiota and colon cells by comparing human microbial communities with those from a primate that has an extreme plant-based diet, namely, the gelada baboon, which is a grazer. The effects of potato (high starch) versus grass (high lignin and cellulose) diets on human-derived versus gelada-derived fecal communities were compared in vitro. We especially focused on the production of short-chain fatty acids, which are hypothesized to be key metabolites influencing appetite regulation pathways. The results confirmed that diet has a major effect on bacterial numbers, short-chain fatty acid production, and the release of hormones involved in appetite suppression. The potato diet yielded greater production of short-chain fatty acids and hormone release than the grass diet, even in the gelada cultures, which we had expected should be better adapted to the grass diet. The strong effects of diet on hormone release could not be explained, however, solely by short-chain fatty acid concentrations. Nuclear magnetic resonance spectroscopy found changes in additional metabolites, including betaine and isoleucine, that might play key roles in inhibiting and stimulating appetite suppression pathways. Our study results indicate that a broader array of metabolites might be involved in triggering gut hormone release in humans than previously thought. IMPORTANCE: One theory for rising levels of obesity in western populations is that the body's mechanisms for controlling appetite evolved to match ancestral diets with more low-energy plant foods. We investigated this idea by comparing the effects of diet on appetite suppression pathways via the use of gut bacterial communities from humans and gelada baboons, which are modern-day primates with an extreme diet of low-energy plant food, namely, grass. We found that diet does play a major role in affecting gut bacteria and the production of a hormone that suppresses appetite but not in the direction predicted by the ancestral diet hypothesis. Also, bacterial products were correlated with hormone release that were different from those normally thought to play this role. By comparing microbiota and diets outside the natural range for modern humans, we found a relationship between diet and appetite pathways that was more complex than previously hypothesized on the basis of more-controlled studies of the effects of single compounds.

On the evolutionary origins of obesity: a new hypothesis

Obesity is an escalating threat of pandemic proportions, currently affecting billions of people worldwide and exerting a devastating socioeconomic influence in industrialized countries. Despite intensive efforts to curtail obesity, results have proved disappointing. Although it is well recognized that obesity is a result of gene-environment interactions and that predisposition to obesity lies predominantly in our evolutionary past, there is much debate as to the precise nature of how our evolutionary past contributed to obesity. The “thrifty genotype” hypothesis suggests that obesity in industrialized countries is a throwback to our ancestors having undergone positive selection for genes that favored energy storage as a consequence of the cyclical episodes of famine and surplus after the advent of farming 10 000 years ago. Conversely, the “drifty genotype” hypothesis contends that the prevalence of thrifty genes is not a result of positive selection for energy-storage genes but attributable to genetic drift resulting from the removal of predative selection pressures. Both theories, however, assume that selection pressures the ancestors of modern humans living in western societies faced were the same. Moreover, neither theory adequately explains the impact of globalization and changing population demographics on the genetic basis for obesity in developed countries, despite clear evidence for ethnic variation in obesity susceptibility and related metabolic disorders. In this article, we propose that the modern obesity pandemic in industrialized countries is a result of the differential exposure of the ancestors of modern humans to environmental factors that began when modern humans left Africa around 70 000 years ago and migrated through the globe, reaching the Americas around 20 000 years ago. This article serves to elucidate how an understanding of ethnic differences in genetic susceptibility to obesity and the metabolic syndrome, in the context of historic human population redistribution, could be used in the treatment of obesity in industrialized countries

Globalização de capacidades tecnológicas inovadoras e o papel de subsidiárias de empresas transnacionais (ETNs) no contexto de países em desenvolvimento: a trajetória de uma empresa do setor de TIC no Brasil

This dissertation seeks to add new evidence to the international debate on globalization of innovation in the developing countries context. Globalization of innovation, in this dissertation, is defined and measured by the types, levels and rate of innovative technological capability accumulation and the underlying technological learning processes (sources of capabilities) at the firm level in late-industrializing countries ¿ or developing countries. This relationship is examined within a large transnational corporation (TNC) subsidiary of the information and communication technology (ICT) sector in Brasil: Motorola do Brasil during over the period from 1996 to 2006. In the international literature there is a strong debate on the extent to which innovative technological capabilities have been spreading internationally. But, the most of the studies are focused on early industrialized countries. In other words, there is still a scarcity of analysis, mainly at the firm level, from the perspective of developing countries. This dissertation supports itself in analytical basis developed in the international literature on accumulation of technological capabilities and learning in the context of developing countries. The learning processes examined in this dissertation are: (i) intra-firm learning processes; (ii) inter-firm learning processes (links between mother and sister companies); and (iii) links between the firm and other organizations of the innovation system (universities, research institutes, among others). Based on first-hand empirical evidence, qualitative and quantitative, collected on the basis of extensive fieldwork, this dissertation examines these issues with adequate level of detail and depth, in this large company in Brazil. The study results suggest that: Concerning the path of the technological capability accumulation, the firm exhibited heterogeneity in the path of accumulation of technological capabilities to distinct functions. For the functions Software Engineering and Process and Management Project the firm reached the Level 6 (Innovative Intermediate Superior), on a scale that ranges from 1 to 7; In relation to technological capability sources, the firm deliberately sought and built sources of knowledge in order to develop and sustain its innovative technological capabilities. The dissertation, thus, contributes to adding new empirical evidence to the debate on globalization of innovative capabilities from a late-industrializing perspective.

Acumulação de competências tecnológicas em processos e produtos e aprendizagem tenológica: o caso da ELETROLUX do Brasil S/A - Unidade de Guabirotuba - Curitiba/PR

This dissertation is concerned with the implications of the learning process on the technological capabilities accumulation. This relationship was examined at the Electrolux do Brasil S/A ¿ Guabirotuba Unity ¿ in Curitiba/PR, over the period of 1980 to 2000. The Brazilian factory products White Goods destined to the Brazilian market as well as to exportation. The Swedish group Electrolux, to which the Brazilian factory belongs to, produces and sell goods to more then 150 countries. Regardless their importance, studies on the accumulation of technological capabilities and the underlying learning process are still scarce in Brazil, especially those focusing on the eletrodomestics products, and more specifically on the refrigerators and freezers industry. Based on a case study in the Electrolux do Brasil S/A, from 1980 to 2000, this investigation examined the influence of the learning process in the paths of the technological capabilities accumulation in the firm. The learning processes were analyzed in the light of the analytical framework proposed by Figueiredo (2001). This framework consists in four key features: variety, intensity, functioning and interaction. The technological capabilities accumulation were studied considering two technological functions: Process and Production Organization Activities and Products Activities. The evidences to classify and describe the paths of technological capabilities accumulation as well as to analyse the learning were mainly qualitative. This investigation joins other previous studies, in which there was noticed that the learning process have great involvement on technical changes, playing a relevant role on the technological capabilities of a company. Based on the investigation done and on the practical utilization of the analytical structure proposed by Figueiredo (2001), we infer that the way and the speed of technological capabilities accumulation are related to how the various learning processes were used by the company. One implied that, in levels from one to six, the studied company cumulated capabilities to level (5). Regarding technological competence, it approached industrialized countries firms, which present level (6), advanced.

O gerencialismo no poder público municipal: o caso da reforma administrativa na empresa de urbanização do Recife

O tema desta dissertação é a reforma do setor público brasileiro, com foco na reforma administrativa de inspiração gerencial, implantada em 2005 na principal empresa pública da capital pernambucana, a URB - Recife. O objetivo final do estudo foi o entendimento dos impactos na gestão da empresa, advindos de tal reestruturação, recorrendo-se parcialmente às percepções que dela tiveram seus funcionários e o corpo de gerentes, conforme reveladas por pesquisa ad hoc aplicada. O estudo foi contextualizado num histórico sumário da administração burocrática no Brasil; destacando-se as iniciativas de reforma na. era Vargas, com o surgimento do DASP, quando se tentou a implantação da burocracia clássica de inspiração weberiana, fazendo-se igualmente referência à segunda grande reforma do Estado brasileiro, realizada no regime militar, regulada pelo Decreto-lei n° 200/67 e considerada a primeira tentativa de reforma de cunho gerencial. No governo Fernando Henrique Cardoso, foi tentada a terceira grande reforma, influenciada pelas idéias econômicas e políticas dos anos oitenta e noventa do século passado em países industrializados, cujos governos apostavam então nos valores e estratégias do mercado, . como a solução mais adequada para os problemas econômicos e sociais, e nas técnicas de gestão do setor priva~o, para tomar mais eficiente a administração pública. Ao lado da concepção administrativa de· vertente gerencial, no Brasil das duas últimas décadas, prosperaram idéias de administração societal, inspiradas em experiências de orçamento participativo, iniciadas na Prefeitura de Porto Alegre em 1989 e hoje espalhadas por centenas de municípios. A reforma da URB - Recife em 2005, também foi analisada quanto à evolução de sua estrutura desde sua instituição em 1973 e as diversas alterações de atribui'4ões e de modelos de gestão ocorridos no período. Concluiu-se, tanto com base na avaliação das respostas à pesquisa referenciada, como pelas próprias observações do autor do estudo, que a reforma focada teve resultados predominantemente desfavoráveis ao desempenho desejável da instituição.

Essays on economic growth

A fundamental question in development economics is why some economies are rich and others poor. To illustrate the income per capita gap across economies consider that the average gross domestic product (GDP) per capita of the richest 10 percent of economies in the year 2010 was a factor of 40-fold that of the poorest 10 percent of economies. In other words, the average person in a rich economy produces in just over 9 days what the average person in a poor economy produces in an entire year. What are the factors that can explain this difference in standard of living across the world today? With this in view, this dissertation is a conjunction of three essays on the economic growth field which we seek a possible responses to this question. The first essay investigates the existence of resource misallocation in the Brazilian manufacturing sector and measures possible distortions in it. Using a similar method of measurement to the one developed by Hsieh and Klenow (2009) and firm-level data for 1996-2011 we find evidence of misallocation in the manufacturing sector during the observed period. Moreover, our results show that misallocation has been growing since 2005, and it presents a non-smooth dynamic. Significantly, we find that the Brazilian manufacturing sector operates at about 50% of its efficient product. With this, if capital and labor were optimally reallocated between firms and sectors we would obtain an aggregate output growth of approximately 110-180% depending on the mode in which the capital share is measured. We also find that the economic crisis did not have a substantial effect on the total productivity factor or on the sector's misallocation. However, small firms in particular seem to be strongly affected in a global crisis. Furthermore, the effects described would be attenuated if we consider linkages and complementarity effects among sectors. Despite Brazil's well-known high tax burden, there is not evidence that this is the main source of resource misallocation. Moreover, there is a distinct pattern of structural change between the manufacturing sectors in industrialized countries and those in developing countries. Therefore, the second essay demonstrate that this pattern differs because there are some factors that distort the relative prices and also affect the output productivity. For this, we present a multi-sector model of economic growth, where distortions affect the relative prices and the allocation of inputs. This phenomenon imply that change of the production structure or perpetuation of the harmful structures to the growth rate of aggregate output. We also demonstrate that in an environment with majority decision, this distortion can be enhanced and depends on the initial distribution of firms. Furthermore, distortions in relative prices would lead to increases in the degree of misallocation of resources, and that imply that there are distinct patterns of structural changes between economies. Finally, the calibrated results of the framework developed here converge with the structural change observed in the firm-level data of the Brazilian manufacturing sector. Thereafter, using a cross-industry cross-country approach, the third essay investigates the existence of an optimal level of competition to enhance economic growth. With that in mind, we try to show that this optimal level is different from industrialized and under development economies due to the technology frontier distance, the terms of trade, and each economy's idiosyncratic characteristics. Therefore, the difference in competition industry-country level is a channel to explain the output for worker gap between countries. The theoretical and empirical results imply the existence of an inverted-U relationship between competition and growth: starting for an initially low level of competition, higher competition stimulates innovation and output growth; starting from a high initial level of competition, higher competition has a negative effect on innovation and output growth. Given on average industries in industrialized economies present higher competition level. With that if we control for the terms of trade and the industry-country fixed effect, if the industries of the developing economy operated under the same competition levels as of the industrialized ones, there is a potential increase of output of 0.2-1.0% per year. This effect on the output growth rate depends on the competition measurement used.

A situation awareness interface for a bi-wheeled industrial hovercraft: design, development and evaluation

The intention of this thesis is to develop a prototype interface that enables an operator to control a bi-wheeled industrial hovercraft that will work within a fusion power plant if the automation system fails. This fusion power plant is part of the ITER project a conjoint effort of various industrialized countries to develop cleaner sources of energy. The development of the interface prototype will be based on situation awareness concepts, which provide a means to understand how human operators perceive the world around, then process that information and make decisions based on the knowledge that they already have and the projected knowledge of the reactions that will occur in the world in response to the actions the operator makes. Two major situation awareness methods will be used, GDTA as a means to discover the requirements the interface needs to solve, and SAGAT to conduct the evaluation on the three interfaces. This technique can isolate the differences an operator has in situation awareness when presented with relevant information given by each of the three interfaces that were built for this thesis. Where the first interface presents the information within the operator’s focal point of view in a pictorial style, the second interface shows the same information within the same point of view has the first interface but only shows it in a textual manner. While the third interface shows the relevant information in the operator’s peripheral field of view. Also SAGAT can provide insight on the question to know if providing the operator with feed-forward information about the stoppage distances of the bi-wheeled industrial hovercraft has any effect on the operator’s decision making.
