The financial crisis and Great Recession have been followed by a jobs shortage crisis that most forecasts predict will persist for years given current policies. This paper argues for a wage-led recovery and growth program which is the only way to remedy the deep causes of the crisis and escape the jobs crisis. Such a program is the polar opposite of the current policy orthodoxy, showing how much is at stake. Winning the argument for wage-led recovery will require winning the war of ideas about economics that has its roots going back to Keynes’ challenge of classical macroeconomics in the 1920s and 1930s. That will involve showing how the financial crisis and Great Recession were the ultimate result of three decades of neoliberal policy, which produced wage stagnation by severing the wage productivity growth link and made asset price inflation and debt the engine of demand growth in place of wages; showing how wage-led policy resolves the current problem of global demand shortage without pricing out labor; and developing a detailed set of policy proposals that flow from these understandings. The essence of a wage-led policy approach is to rebuild the link between wages and productivity growth, combined with expansionary macroeconomic policy that fills the current demand shortfall so as to push the economy on to a recovery path. Both sets of measures are necessary. Expansionary macro policy (i.e. fiscal stimulus and easy monetary policy) without rebuilding the wage mechanism will not produce sustainable recovery and may end in fiscal crisis. Rebuilding the wage mechanism without expansionary macro policy is likely to leave the economy stuck in the orbit of stagnation.

Esta tese relaciona-se ao tema da acumulação de capacidades tecnológicas em nível de empresa, suas fontes (mecanismos de aprendizagem) e suas implicações para a performance competitiva empresarial, em indústrias relacionadas a recursos naturais no contexto de economias emergentes. Durante os últimos 40 anos muito se avançou no campo da pesquisa sobre acumulação de capacidades tecnológicas em nível de empresas em economias emergentes. Porém, ainda há importantes lacunas a serem exploradas particularmente em relação a natureza e dinâmica de trajetórias de acumulação de capacidades tecnológicas intra-empresariais, no contexto de indústrias relacionadas a recursos naturais, especialmente na mineração. O objetivo da pesquisa aqui reportada é contribuir para minimizar esta lacuna. Particularmente, esta tese explora variações intra-empresariais de trajetórias de acumulação de capacidades tecnológicas, suas fontes (mecanismos subjacentes de aprendizagem) e algumas implicações que são geradas para a performance competitiva da empresa, no âmbito da indústria de mineração no Brasil, especificamente na empresa mineradora Vale, no período entre 1942 e 2015. Para alcançar este objetivo, a pesquisa apoia-se na combinação das literaturas de acumulação de capacidade tecnológica, inovação, aprendizagem e desenvolvimento industrial para a construção da base conceitual. Em paralelo, a pesquisa vale-se de um desenho de pesquisa qualitativo e indutivo baseado em evidências primárias com base em extensivos trabalhos de campo. Esse desenho de pesquisa é operacionalizado a partir de um estudo de caso individual em profundidade na Vale, no âmbito de três grandes áreas tecnológicas: prospecção e pesquisa mineral, lavra, e processamento mineral. Por meio da implementação dessa estratégia, a pesquisa encontrou: (1) Trajetórias de acumulação de capacidades tecnológicas relativamente distintas entre as três áreas de análise. Especificamente: (i) na área de prospecção e pesquisa mineral observou-se uma trajetória de seguidora tecnológica que alcança posição de liderança mundial em inovação e produção; (ii) na área de lavra também evidenciou-se uma trajetória de seguidora tecnológica que alcança posição de liderança mundial em inovação e produção, porém, com acumulação tardia de capacidades tecnológicas; e (iii) na área de processamento mineral houve o alcance precoce de posição de liderança mundial em inovação e produção a partir da criação de uma trajetória distinta da já mapeada pelos líderes globais. As trajetórias de acumulação de capacidades tecnológicas convergem para uma situação similar a partir de 2011 quando as três áreas apresentaram posição de liderança mundial em inovação e ao mesmo tempo demonstraram indícios de entrada em um processo de estagnação, que restringe as oportunidades de entrada em novas trajetórias tecnológicas e de entrada em novos negócios. (2) As variações encontradas nas trajetórias de acumulação de capacidades tecnológicas são explicadas pela maneira pela qual diferentes mecanismos subjacentes de aprendizagem foram combinados e utilizados pela empresa. Foram encontradas quatro combinações de mecanismos de aprendizagem que contribuíram para explicar as diferentes direções das trajetórias de acumulação de capacidades tecnológicas. (3) As variações nas três trajetórias de acumulação de capacidades tecnológicas geraram implicações distintas para a performance competitiva, mais especificamente em termos de performance inovadora, operacional/ambiental e de novos negócios. Os resultados da pesquisa geram contribuições para o entendimento do relacionamento intra-empresarial entre acumulação de capacidades tecnológicas e os mecanismos de aprendizagem subjacentes. E contribuem para o entendimento da mineração como uma indústria que oferece oportunidades para inovações significativas que, inclusive podem implicar na diversificação do tecido industrial nacional. Portanto, tal indústria deve receber atenção especial por parte de decisores de políticas públicas e de ações empresariais para evitar que empresas com alto potencial inovativo desconstruam suas capacidades inovadoras e consequentemente limitem seus impactos para o desenvolvimento tecnológico e econômico no contexto de economias emergentes.

Increasing competition caused by globalization, high growth of some emerging markets and stagnation of developed economies motivate Consumer Packaged Goods (CPGs) manufacturers to drive their attention to emerging markets. These companies are expected to adapt their marketing activities to the particularities of these markets in order to succeed. In a country classified as emerging market, regions are not alike and some contrasts can be identified. In addition, divergences of marketing variables effect can also be observed in the different retail formats. The retail formats in emerging markets can be segregated in chain self-service and traditional full-service. Thus, understanding the effectiveness of marketing mix not only in country aggregated level data can be an important contribution. Inasmuch as companies aim to generate profits from emerging markets, price is an important marketing variable in the process of creating competitive advantage. Along with price, promotional variables such as in-store displays and price cut are often viewed as temporary incentives to increase short-term sales. Managers defend the usage of promotions as being the most reliable and fastest manner to increase sales and then short-term profits. However, some authors alert about sales promotions disadvantages; mainly in the long-term. This study investigates the effect of price and in-store promotions on sales volume in different regions within an emerging market. The database used is at SKU level for juice, being segregated in the Brazilian northeast and southeast regions and corresponding to the period from January 2011 to January 2013. The methodological approach is descriptive quantitative involving validation tests, application of multivariate and temporal series analysis method. The Vector-Autoregressive (VAR) model was used to perform the analysis. Results suggest similar price sensitivity in the northeast and southeast region and greater in-store promotion sensitivity in the northeast. Price reductions show negative results in the long-term (persistent sales in six months) and in-store promotion, positive results. In-store promotion shows no significant influence on sales in chain self-service stores while price demonstrates no relevant impact on sales in traditional full-service stores. Hence, this study contributes to the business environment for companies wishing to manage price and sales promotions for consumer brands in regions with different features within an emerging market. As a theoretical contribution, this study fills an academic gap providing a dedicated price and sales promotion study to contrast regions in an emerging market.

The necessity of the insertion of the capital of Rio Grande do Norte in the world-wide commercial scene and its claim as the seat of political power, in ends of nineteenth and beginning of twentieth century, determined the direction of urban interventions undertaken by government to restructure the city. In that matter, there were several actions of improvements and embellishment in Natal, which had, as a starting point, the adequacy works of the port, located in the Ribeira quarter, with the aim of ending the physical isolation that reinforced its economic stagnation. Besides the problems faced in the opening bar of the Potengi River, and would complement the required improvements, other barriers demonstrate the tension established between the physic-geographic field and the man: the flooded and slope which connected Cidade Alta and Ribeira the first two quarters of the city.The execution of these works demanded knowledge whose domain and application it was for engineering. But, how the actions done for the engineers, in sense to transform natural areas into constructed spaces made possible the intentional conformation of the quarter of the Ribeira in a commercial and politician-administrative center, in the middle of the XIX century and beginning of the XX? Understand, therefore, the employment effects of technology on the physical-geographical Ribeira, is the objective of this work that uses theoretical and methodological procedures of Urban Environmental History, by analyzing the relationship between the environment and the man, mediated by knowledge and use of technologies. The documental research was used, as primary sources, the Messages of the Provincial Assembly Government that later became the Legislative Assembly of Rio Grande do Norte reports and articles on specialized publications, in addition to local newspapers. The work is structured in five chapters. First, some comments about Urban Environmental History (Chapter 1) supplemented with analysis of the conceptual construction of nature in the Contemporary Era and its application in the city (chapter 02), the following chapters (03 and 04) deal with the rise of engineers as a active group in the Brazilian government frameworks and their vision about the nature inside the urban environment and it is studied how the professional technicians dealt with the improvement work of the harbor and in the shock with the natural forces. Other works that would complement this "project" of modernization and had had natural obstacles to be removed the Ribeira flood and slope constitute the subject of the fifth chapter. Finally, some final considerations retake the initial discussions aiming an association between the technique and the nature as junction elements inside the process of constitution of a Modern Natal

The northeastern semiarid is a region that presents a serious picture stagnation or slowness of the economic growth, beyond the presence of social pointers below of the averages national and regional. The half-dryness conditions become the improper region for many agricultural cultures, what it affects the local populations directly, as well as the economy that is based mainly on agriculture. Cnidoscolus quercifolius Pohl, popularly know as favelone is a native species of the semiarid region that withholds great potential for the development of the region in virtue of its multiple uses. Being an oleaginous, its production in familiar farmings makes with that biodiesel either for the misery an important alternative eradication for the possibility of occupation of enormous contingents of people. The present study it aims at to evaluate the germination of the faveleira without thorns under conditions of water and saline stresses, main stresses which the vegetal species of the semiarid one are submitted; beyond verifying the acceptance of the species for agriculturists of a cooperative in the city of Apodi/RN. The methodology used for germination corresponds to using treatments with polyethylene glycol and sodium chloride to assess water and salt stress respectively, being held in rolo. O system approach used for the verification of acceptance of faveleira was the use of interview with farmers cooperative in the study area determined. In this direction it was verified that the faveleira is a resistant species the conditions of drought and salinity of the ground, factor of great relevance, since one is about a species with high added value, making possible the development for the semiarid region. It was verified that the agriculturists are favorable the introduction of the faveleira and reveal receptive the idea to cultivate a species with potential for production of biodiesel

CONTEXTO E OBJETIVO: em crianças, a esteatose hepática pode se relacionar a erros inatos do metabolismo (EIMs) ou à doença hepática gordurosa não-alcoólica (DHGNA). O objetivo deste estudo foi avaliar e caracterizar esteatose de causa indeterminada por meio de análises morfológica e morfométrica em tecido hepático. TIPO DE ESTUDO E LOCAL: Estudo transversal nos Departamentos de Patologia da Faculdade de Ciências Médicas da Universidade Estadual de Campinas (FCM-Unicamp) e Faculdade de Medicina de Botucatu da Universidade Estadual Paulista (FMB-Unesp). MÉTODOS: Foram utilizadas 18 biópsias hepáticas consecutivas obtidas de 16 pacientes com idade variando de 3 meses a 12 anos e 9 meses, inseridas num banco de dados no período do estudo, que foram analisadas por microscopia óptica e eletrônica. Na microscopia eletrônica, foi realizada determinação da densidade mitocondrial e da área superficial média das mitocôndrias nos hepatócitos. Dez pacientes com idade variando de 1 a 14 anos foram usados como grupo controle. RESULTADOS: Foi detectada esteatose pura, não acompanhada por fibrose ou outra alteração histológica. Foi verificado que, na predominância de esteatose microvesicular, houve aumento significativo da área mitocondrial média. CONCLUSÃO: A esteatose microvesicular pode estar relacionada à hepatopatia mitocondrial primária, principalmente devido à redução na β-oxidação ou parcial estagnação da fosforilação oxidativa. Por essas razões, esta forma de esteatose (que não pode ser chamada de pura) possivelmente represente uma fase inicial no amplo espectro da DHGNA. Chamamos a atenção para casos de esteatose no grupo pediátrico com predomínio da forma microvesicular, uma vez que pode haver associação com desordens mitocondriais.

Cet article cherche à dresser, sous la perspective historique, le bilan de la situation des pays périphériques dans les dernières trentes années. Pour cela, il aborde particulièrement les enjeux du développement dans la phase de la globalisation du capital. Ce travail s'appuie surtout sur les études de la vaste bibliographie publiée récemment. Dans quelle mesure la relance du développement concernant plusieurs secteurs stagnés de la périphérie deviendrait-elle une réelle possibilité? Autour de cette question, que nous trouvons centrale dans l'actuelle conjoncture, nous entamons quelques réflexions. Nous envisageons montrer que la stagnation économique à laquelle des nombreux pays non développés font face ne découle pas en partie d'une crise sociale et économique ouverte dans les années soixante-dix et qui s'élargit jusqu'à nos jours malgré les tentatives de restructuration de la société capitaliste. Les stratégies et les mesures politiques à caractère néo-liberal aussi auraient énormément contribué à cette situation étant donné qu'elles ont renforcé les amarres financières qui ont étranglé pour une part les économies périphériques. Outre ces difficultés, ces pays affronteraient les limites écologiques du capitalisme. La relance du développement dans un nouveau stade exigeant la croissance économique, la justice sociale et la préservation de la nature amènerait à une rupture face au capitalisme.

Classical shell-and-tube heat exchangers are usually equipped with segmental baffles. These baffles serve two basic functions: (a) they provide tube supports, thereby preventing or reducing mechanical problems, such as sagging or vibration; (b) they direct the fluid flow over the tubes so as to introduce a cross-flow component, thereby increasing the heat transfer. Segmented baffles have several sources of performance loss, some due to various leakage flows and others caused by stagnation zones. A new concept of longitudinal flow heat exchanger - based on placing twisted tapes along the tube bundle subchannels - was developed to mitigate drawbacks of other types of tubular heat exchangers. In this paper, a numerical model has been implemented in order to simulate the thermal-hydraulic feature of tubular heat exchangers equipped either with segmental baffles or with subchannel twisted tapes. The tube bundle has been described by means of an equivalent porous medium type model, allowing a macroscopic description of the shell-side flow. The basic equations - continuity, momentum and energy - have been solved by using the finite volume method. Typical numerical results have been compared with experimental data, reaching a very good agreement. A comparative analysis of different types of heat exchangers has been carried out, revealing the satisfactory thermal-hydraulic efficiency level of the twisted tapes heat exchangers.

Ablation is a thermal protection process with several applications in engineering, mainly in the field of airspace industry. The use of conventional materials must be quite restricted, because they would suffer catastrophic flaws due to thermal degradation of their structures. However, the same materials can be quite suitable once being protected by well-known ablative materials. The process that involves the ablative phenomena is complex, could involve the whole or partial loss of material that is sacrificed for absorption of energy. The analysis of the ablative process in a blunt body with revolution geometry will be made on the stagnation point area that can be simplified as a one-dimensional plane plate problem, hi this work the Generalized Integral Transform Technique (GITT) is employed for the solution of the non-linear system of coupled partial differential equations that model the phenomena. The solution of the problem is obtained by transforming the non-linear partial differential equation system to a system of coupled first order ordinary differential equations and then solving it by using well-established numerical routines. The results of interest such as the temperature field, the depth and the rate of removal of the ablative material are presented and compared with those ones available in the open literature.
