Princípios da construção enxuta no processo de planejamento de uma construtora de grande porte de Natal (RN)

Considered as one of the oldest activities done by men, the civil construction represents one of the most important sectors for the economic growth of a country, in spite of the low results of growth in the past few years and also in the current year. To make this industry grow, even with an unfavourable economic scenario, it is necessary to implement an effective planning in its activities. This is one of the most important concepts brought by the Lean Construction philosophy, which had its origin through the adaptation of the concepts established by the Toyota Production System (TPS) or Lean Production. By having as a scenario the city of Natal\RN, the main goal of this dissertation consists in investigating how the 11 principles of the lean construction influenced the schedule of a construction field that started to implement its lean concepts. As a methodology, it was used the case study of a big enterprise located in Natal (RN). During the execution of the method, documents related to the short-term, midterm and long-term planning were analysed , aiming to describe its planning process; it was also described the factors that caused the delays at the enterprises’ field ;in addition, a comparison was made between the results obtained at the case study and the ones presented at the literature; in the end, the actions were listed by the company, which had the purpose to solve the main causes of delays, verifying if they were linked to the lean construction principles. This research finds its reason of existence in the relevance of its theme at the nowadays reality of the construction industry, since the principles of the lean construction uphold the reduction of processes that are useless, diminishing wastes as well as costs in construction. The relevance is perceived for the academy, in terms of the possibility to discuss if the concepts established by the lean production are being adapted to the civil construction sector and how this adaptation is influencing at the buildings planning project. Economic importance, because with the reduction of the wastes and costs, the companies may reduce the building´s value into a more accessible value, even with the sector´s lower growth. And social significance, because lean construction gives a better participation of the labour at the planning activity. Among the main results, the high frequency of planning errors stands out, mainly the programming deviations and not the task programming, as well as the execution errors, low productivity and activities executed by the workers. Amongst the 11 principles of lean construction, only five were related with the 12 actions analysed by the author. From the 12 actions, four were completely cohesive to one or more from these five principles. Some improvement proposals were also highlighted and established by the research.

Políticas públicas de economia solidária: uma avaliação do PCPR II na microrregião de Angicos do Rio Grande do Norte

The Solidarity Economy is considered in this work as a development option. Talk about it is to think in the workforce as a producer of material wealth and, above all , subjective , therefore it is necessary to take into account that these relations coexist different types of practices that encompass emotions , lifestyles , etc. This research has as an object of study evaluating the effectiveness of public policy for Solidarity Economy, microrregion Angicos / RN, demonstrating how the Solidarity Economy has encouraged the development not only as a driving force for economic growth, but as the expansion capabilities and freedoms. The Solidarity Economy has several definitions, and despite having its origin in the cooperative movement, is a concept under construction. Focused on the discussion of public policy, is now understood as a proposal for employability, either as a generator of employment and income, reflecting its polymorphism. Theories and concepts developed by Amartya Sen is an important analytical tool for understanding the Solidarity Economy as a development strategy. When speaking of instrumental freedoms, Senniana theory contributes to reflection on how participants socioeconomic actions are becoming active agents of change i n their own freedoms. The analysis was based on the discussion of development beyond economic bias, using the lines of the vari ous local stakeholders with PCPR II, p hase 2, for microrregion Angicos / RN, comprising: public managers, technical advisors and beneficiaries of the program rural poverty alleviation. Besides the discussion of the economic organization of the RN and its spatial distribution, the survey brings the result that the Solidarity Economy in microrregion Angicos / RN contributed to the dev elopment as freedom, proving the effectiveness of public policy by allowing an improvement in the quality of life, enabling efetivations, even without major proportions.

Esforços governamentais locais para o desenvolvimento: desenhos, tendências e limites dos Fundos de Desenvolvimento Industrial nos estados do Rio Grande do Norte, Maranhão e Ceará (1985-2010)

This research aimed to analyze the main government efforts to promote economic development in the Northeast, from 1985 to 2010, under the view that growth is crucial for increasing industrialization process and allows for more significant growth patterns. The analysis was the context in which state governments react to the abandonment of developmental line the federal level, in the 1980s, incorporating features of the actions called endogenous regional development and providing local players with greater responsibility in the development process. Justifies the need to analyze the following scenario: state governments in northeastern Brazil using relevant part of its resources to finance the installation and expansion of companies through tax incentives, with a view to generating income and employment, whilst waiting for an increase in output and a positive change in economic dynamism. In addition, it puts in question the fact that these policies receive such importance of state administrations for the purpose of achieving regional development. It was left to consider, therefore, the contents of the shares elected by state governments to examine the scope of these policies both in the pattern of growth, the transformation of the industrial sector and the development of the region attention to changes in state production structures. Due to limitations on the availability of data and time to carry out research, we were elected three states for the study: Rio Grande do Norte, Ceará and Maranhão. The study found that, despite the contribution of policies analyzed to economic growth, sub-national states are unable to compensate for the lack of development agencies structured at the federal level.

Análise de microestrutura e de características geotécnicas de misturas de resíduo de polimento de porcelanato e solo

Brazil is a country in development, rich in natural resources. In order to grow sustainably, it is necessary to Brazil to preserve its environment, which is an expressive challenge, especially to industries, such as those producing ceramic materials. This study was developed using Porcelain Tile Polishing Residue (RPP) in blends with soil to build compacted fills. This residue is a slurry generated during the polishing process of porcelain tiles and contains powdery material from the polished tile, the abrasives used during the process and cooling water. The RPP was collected from a private company located in Conde/PB and it was mixed with a sandy-clayey soil, to build the fills. Laboratorial tests were conducted with pure soil, pure RPP and blends in proportions of 5%, 10%, 15% and 20% of RPP in addition to the dry mass of pure soil. The Chemical and Physical Characterization tests performed were: specific solid weight, grain size distribution, laser analysis of grain size distribution, Atterberg limits, X ray fluorescence, X ray diffraction, scanning electron microscopy and soil compaction,. The materials and blends were also compacted and direct shear tests and plate load tests were performed. Plate load tests were conducted using a circular plate with 30 cm diameter, on specimens of pure soil and 5% blend, compacted in a metallic box inside the Soil Mechanics Laboratory of the Federal University of Rio Grande do Norte, Brazil. Both mechanical tests performed were conducted under inundated conditions, willing to reduce the influence of soil suction. An evaluation of the results of the tests performed shows that RPP is a fine material, with grain size distribution smaller than 0,015mm, composed mainly of silica and alumina, and particles in angular shape. The soil was characterized as a clayey sand, geologically known as a lateritic soil, with high percentages of alumina and iron oxide, and particles with rounded shape. Both the Soil and the blends presented low plasticity, while the residue showed a medium plasticity. Direct shear tests showed that the addition of RPP did not cause major changes into blends’ friction angle data, however, it was possible to note that, for the proportions studied, that is a tendency of obtain lower shear stresses for higher percentages of RPP in the blends. Both pure soil and 5% mixture showed a punching disruption for the Plate load test. For this same test, the allowable stress for 5% mixture was 44% higher than the pure soil, and smaller vertical settlement results for all stresses.

Plano de desenvolvimento sustentável e articulação de políticas públicas: o controle de políticas ambientais pelo poder judiciário

The right to the preservation of a healthy environment is perceived as a Fundamental Right, inserted in the National Constitution and referring to present and future generations. The preservation of the environment is directly connected to the right to Health and Human Dignity and, therefore, must be treated as a personal right, unavailable, claiming for a positive response from the Brazilian State, through the development of related public policies, control of potentially harmful economic activities, with special focus on the principles of precaution and solidarity. The Brazilian judiciary must thus be attentive to the guardianship of the Fundamental Right. The judiciary control over the execution of public policies is based on obeying the principle of the separation, independence and harmony between the Powers, however it should never deviate from the constitutional obligation of caring for the effectivation of the rights and guarantees within the Magna Carta. In the balance between the principle of human dignity, from which springs the right to a healthy environment and the principle of separation of powers, the former should prevail, maintaining the latter to a core minimum.

Dinâmica industrial, emprego e pobreza no Brasil, uma abordagem alternativa

Between 2003 and 2014 Brazil has increased exports by 52%, increased the formal employment and paid employment by 19% and reduced multidimensional poverty by 42%. The purpose of this work is to test the hypothesis that there is a Brazilian Growth Virtuous Circle where these three variables would be connected in order to increase exports and reduce poverty through the salaries transfer of funds. The construction of the hypothesis is made for Export Industry through ideas Verdoorn, Kaldor and Thirlwall presenting the export industry as an engine of economic growth. To present employment acting directly on economic growth is used Wage Led Rowthorn approach. The Capability Approach of Amartya Sen is used to understand the Multidimensional Poverty. The hypothesis was tested using data from the National Household Survey and Aliceweb between 2003 and 2014 with the use of the Generalized Method of Moments and the generation of elasticities between export and employment, employment and poverty, and export and poverty.

Padrão de especialização e saldo comercial da China com Estados Unidos, Europa e Ásia no início do Século XXI

The rise of China has been providing various effects on developed and developing countries, particularly its Asian neighbors which compete in third markets, such as the U.S., Europe and Japan this sense, the present study aimed to analyze the pattern of Chinese trade with two different groups of countries: the Asian neighbors (Asian Tigers and Dragons) and developed countries (United States, Europe and Japan) during the 2000s. To this end, this paper adopts the methodology of second breakdown of trade technological intensity proposed by Lall (2000). Furthermore, to analyze the intensity of trade between these economies as well as potential threats over their Chinese business partners close, we calculated the following indicators of trade: Trade Intensity Index (TII), Trade Orientation Index (TOI) , Intra-Industry Trade Index (ICII), Index Of Revealed Comparative Advantage (RCA), and, finally, the Contribution To The Balance Index (ICS). The main result achieved is the existence of China\'s trade patterns differ for each group of countries, according to the type of expertise of each partner.

A pedagogia industrial da FIEMG: um estudo sobre o pensamento empresarial a partir da revista vida industrial (1961-1974)

The present research results of the studies and debates inherent in PhD in Education at the Graduate Program in Education at the Federal University of Uberlândia, belonging to the Research Line "Politics and Knowledge in Education." This thesis aims to analyze the contradictory meaning of education as training human history, specifically educational representative under the logic of the industrial business associated FIEMG (Federation of Industries of the State of Minas Gerais) in the context 1961-1974. This definition is justified by the historical fact that it was a period marked by the cyclical crises of capital and their impacts in the final phase of the industrialization process in Brazil: it starts with one of the apexes of economic growth in the country , driven by national developmental , continues with a severe political crisis in 1966 , also impacting the economic sphere, and finally, with the constant quest for economic stability even under high prices, hatch the factors that led to the Brazilian economy to the context of the "Economic Miracle". For this, it was necessary to link the debate between education and work from the perspective of historical materialism and dialectical their subsidies theoretical-methodological and epistemological. In the first chapter, we designed a "State of the art" category "human formation", conceived as a process of education and history, from the Marxist assumptions, aiming at the reconstruction of concepts and meanings of which is the formation of workers in contradictory logic, the bias of comprehensive training and the prospect of capital accumulation. Then, in the second chapter, we present a review about industrialization, the industrial business and its development perspective 1961-1974. The third chapter was established on a contextualization of the state and its peculiarities, the industrial business and its proposed development both nationally and at the state (Minas Gerais). Finally, in the fourth chapter, was organized dialogue with the sources, from a historical survey of the shares of the industrial business with an emphasis on education, which converged in a pedagogy industrial consolidation in line with the political and economic conditions specific period from 1961 to 1974. It has mailing bibliographic reference business thinking expressed in the concreteness of training workers and industry of Minas Gerais, in agreement with the demands of work and training of mining companies. The thesis of this study is the defense that the corporate actions which constituted pedagogy industrial concepts were articulated to political and economic development in Brazil, since the discipline to work imposed by such conceptions met the human worker training geared to the accumulation the general capital and industrial capital in particular. Establish, therefore, different logics, the state level, the scope of private foreign capital and domestic private capital, which came up the process of capital accumulation, loading, contradictorily, the possibilities of building the human beyond capital, or a teaching job.

Health reforms in Latin America: processes and results

Two types of health reforms in Latin America are analysed: one based on insurance and service commodification and the one referred to the unified public systems of progressive governments. Health insurance with explicit service packages has not fulfilled their purposes of universal coverage, equal access to necessary health services and improvement of health conditions but has opened health as a field of profit making for insurance companies and private health providers. The national health services as a state obligation have developed territorialized health services and widened substantially timely access to the majority of the population. The adoption of an integrated and wide social policy has an impact on population well fare. It faces some problems derived from the old health systems and the power of the insurance and medical complex.

Envelhecimento populacional, mercado de trabalho e políticas públicas de emprego nos países da OCDE

O objetivo deste trabalho é apresentar e analisar sucintamente as consequências do processo de envelhecimento populacional no mercado de trabalho e nas políticas públicas de emprego nos países da Organização de Cooperação para Desenvolvimento Econômico (OCDE). Uma pesquisa bibliográfica composta por seleção, análise, resumo, complementação e confrontação das referências bibliográficas é adotada. As estatísticas disponibilizadas pela Organização das Nações Unidas (ONU) e Organização de Cooperação para Desenvolvimento Econômico (OCDE) são as fontes de dados empíricos e sempre que possível os dados referente ao Brasil são inseridos. O impacto econômico do envelhecimento populacional são evidenciados por meio dos efeitos diretos e indiretos. Os efeitos diretos estão associados à quantidade e à qualidade do emprego e os efeitos indiretos correspondem à redução dos recursos econômicos necessários para lidar com o envelhecimento, à interferência nas decisões dos indivíduos e, ainda, à pressão sobre os sistemas de educação, de seguro social e de saúde. As políticas públicas de emprego podem resolver ou amenizar os efeitos considerados negativos do processo de envelhecimento populacional sobre o mercado de trabalho e, consequentemente, sobre o crescimento econômico dos países. Destaca-se que os países membros da OCDE investigados neste trabalho estão incentivando o retorno dos trabalhadores mais velhos e idosos ao mercado de trabalho, por meio das políticas públicas de emprego, em especial, as políticas ativas, tais como: reciclagem, treinamento, orientação e realocação.

Breve reflexão teórica acerca da relação entre população e economia

O objetivo principal deste trabalho é apresentar uma breve reflexão acerca do debate teórico presente na literatura internacional sobre os efeitos econômicos do envelhecimento populacional, especialmente sobre o mercado de trabalho. Foi adotada para tal uma pesquisa bibliográfica composta por seleção, análise, resumo, complementação e confrontação das referências sobre o assunto. Os impactos econômicos do envelhecimento populacional sobre o mercado de trabalho podem ser caracterizados por seus efeitos diretos e indiretos. Os efeitos diretos impactam o tamanho e a qualidade do emprego. Os efeitos indiretos influenciam na redução dos recursos econômicos necessários para lidar com o envelhecimento, interferem nas decisões dos indivíduos e, ainda, exercem pressão sobre os sistemas de educação, de seguro social e de saúde. Diversos países já estão vivenciando o envelhecimento populacional. Assim, políticas voltadas para a manutenção ou reinserção dos idosos saudáveis no mercado de trabalho podem ser fundamentais para o crescimento econômico futuro destes países.

Mobilidade sustentável : interação entre veículos motorizados e utentes vulneráveis da via pública

O automóvel tem sido nas últimas décadas o principal meio de transporte para a realização de deslocações diárias. Este é um panorama tanto a nível Nacional como Europeu e deve-se ao crescimento económico e aos investimentos centrados em infraestruturas rodoviárias. A organização das atividades e o planeamento nos meios urbanos está, muitas vezes, projetada em função do automóvel e pouco preparado para outras formas de mobilidade, nomeadamente para peões e ciclistas. Existe uma necessidade de mudança deste panorama e a necessidade de uma sociedade que privilegie os modos de transporte suave. No entanto, surge a necessidade de garantir a segurança dos utentes mais vulneráveis da via pública. Esta dissertação de Mestrado tem como principal objetivo analisar de que forma a sinistralidade viária para peões e ciclistas tem evoluído nas freguesias abrangidas pela atividade da Polícia de Segurança Pública (PSP) de Aveiro e quais as principais dificuldades que estes enfrentam nas suas deslocações diárias. Para alcançar este objetivo foram analisados dados de sinistralidade viária fornecidos pela PSP do comando distrital de Aveiro que envolviam a interação de veículos motorizados e utentes vulneráveis da via pública (peões ou ciclistas). Numa segunda fase foi elaborado um inquérito, com o objetivo de perceber as principais dificuldades encontradas pelos utentes da Universidade que privilegiam os modos de deslocação suave nas suas viagens diárias. Este estudo revelou que para a área em estudo, no concelho de Aveiro, o número de acidentes que envolvem a interação de veículos motorizados com utentes vulneráveis da via pública aumentou 5% de 2012 a 2013 e 4% de 2013 a 2014. Os utentes com idades superiores a 55 anos revelaram-se os mais vulneráveis, não só em termos de número de ocorrências mas também na gravidade de lesões, representando 50% de mortes e feridos graves, Em termos de atropelamento de peões existe uma forte tendência para peões do sexo feminino (73%), em oposição ao perfil do condutor atropelante onde 69% são do sexo masculino Em relação a acidentes envolvendo ciclistas, 68% dos lesados são do sexo masculino. Uma possível explicação poderá consistir numa maior utilização de bicicletas por parte dos mesmos, como foi comprovado na amostra recolhida no inquérito, mas não existem mais estatísticas em Aveiro sobre a distribuição por género dos utilizadores de bicicleta. Do inquérito efetuado conclui-se que os principais problemas encontrados pelos utentes inquiridos são, à semelhança de peões e ciclistas, a falta de sensibilização dos automobilistas e as condições meteorológicas. Em terceiro lugar encontra-se, para os peões, o aumento do risco de atos de vandalismo e assaltos e, para os ciclistas, a falta de vias dedicadas. Por outro lado, as principais motivações são, tanto para peões como para ciclistas, o custo reduzido ou nulo e a facilidade de locomoção.

A Política Externa da União Europeia no Ártico

É através da política externa que os atores das relações internacionais procuram concretizar os seus objetivos além das suas fronteiras. O Ártico é atualmente uma região alvo da política externa de atores das relações internacionais, entre eles Estados,organizações internacionais, multinacionais, entre outros. Sendo um território quase inexplorado, sabe-se que é extremamente rico em recursos naturais e energéticose que,com as alterações climáticas, estes recursos podem ser explorados. Com o derretimento da camada de gelo, o Oceano Ártico torna-se também uma rota de navegação rápida, o que intensificará o comércio internacional. No entanto, não são apenas oportunidades de crescimento económico que surgem do degelo do Ártico, mas também sérios riscos económicos, ambientais e securitários, aos quais a União Europeia não está alheia. Neste sentido, a organização europeia tem vindo a aplicar os seus esforços de política externa para desenvolver uma política que vá ao encontro dos seus objetivos na região, salvaguardando assim a sua segurança e também os seus interesses. Numa análise teórica, este trabalho procura previamente entender o que é a política externa, qual o papel da União Europeianesse âmbitoe quais as motivações para uma política externa europeia para o Ártico. Também se pretende mostrar a crescente importância da região do Ártico, e como este crescimento está fortemente ligado ao fenómeno das alterações climáticas. Sob a análise empírica, procura-se evidenciar a forma como a União Europeia está a desenvolver a sua política orientada para a região, para que no final do trabalho, cruzando a teoria com a parte empírica, fazer uma leitura da política europeia de acordo com as teorias das relações internacionais. Para dar forma ao trabalho, a metodologia utilizada foi a consulta de fontes académicas, a partir de centros de investigação ligados ao Ártico,como o Smithsonian Arctic Studies Center, o International Arctic Research Center eo Arctic Centre da Universidade da Lapónia, além de fontes documentais de diferentes organizações internacionais e documentos oficiais da União Europeia. Pode concluir-se que a União Europeia tem desenvolvido uma estratégia tendencialmente realista, pois procura sobretudo obter a sua segurança em relação às consequências do degelo do Árticoe limitar as oportunidades de crescimento dos restantes atores da região, apesar de o fazer utilizando políticas e estratégias de caráter pluralista.
