Challenges for the European Union in times of crisis: reactions

Since the beginning of its existence in the form of communities, this entity faced a lot of challenges that could had been stopped the European dream without the fast, prompt and appropriate reaction of the decision makers. There were a lot of difficult times in its history of more than 60 years but the ambition and need of going forward on the way of integration prevailed and today we can talk about European Union as one of the most important global players, having one of the most complex and fascinating political systems. The tenacity and the willing to succeed off the decision makers made this possible. Moments like “The Empty Chair Crisis“, changes with regards to the decision- making process, convenient for ones but inconvenient for the others, lack of consensus with regards to the new accessions, the big changes that Europe went through in the late 80s etc. showed that the decision makers can have an appropriate response whatever the problem would be and that we must stay together and go on dreaming to a united nation in the form of a federation. Nowadays we are facing maybe the most difficult moment in European Union history. Many of the member states were and still are on the edge. A lot of immediate and prompt actions were taken since the start of financial crisis, either political or economic, drove by the need of going on. We are too much into the integration process, too much dependent one of each other so that we cannot stop and simply go back only to the concept of national state.

Les coalitions politiques et l'orientation du changement économique et politique aux États-Unis : la Grande Dépression et la Grande Récession comparées.

Ce mémoire s’intéresse au concept de crise, économique et politique, comme source de changement idéologique et politique. Au travers de l’étude de l’austérité économique, il sera possible d’identifier des différences majeures entre deux épisodes de troubles économiques importants, la Grande Dépression et la Grande Récession. Alors que la Grande Dépression est caractérisée par une double crise, économique et politique, la Grande Récession, elle, demeure un choc essentiellement économique. L’absence de contagion dans le système politique explique la ténacité d’une idée comme l’austérité, de retour depuis la révolution néolibérale des années 80. L’austérité économique s’est adaptée et s’aligne maintenant aux intérêts d’une frange importante de la coalition démocrate. La persistance de l’allure des coalitions politiques depuis le dernier grand réalignement témoigne de l’absence de transformation majeure du mode d’action étatique, ce qui constitue une différence importante entre les deux crises.

IDENTIDADES E TEOLOGIAS NO PRIMEIRO CÂNTICO DO SERVO DE YHWH: Estudo exegético de Isaías 42,1-9 SÃO BERNARDO DO CAMPO 2014

A identidade do Servo de YHWH sempre foi um grande desafio para a pesquisa bíblica. Quem seria esse Servo? Não se pretende saber historicamente quem foi o Servo de YHWH, pois isso é uma tarefa impossível. Pretende-se levantar algumas pistas a partir do contexto histórico e do próprio texto do Dêutero-Isaías que permita pensar na possibilidade de que uma comunidade exilada na Babilônia fosse chamada de Servo e destinada por YHWH para tal missão. Na perícope de Is 42,1-9, YHWH convoca o Servo para uma missão bem específica: fazer sair o direito para as nações. Esse direito que o Servo fará sair às nações é o direito de YHWH que se manifesta na libertação concreta de todos os encarcerados. O Servo com suas posturas silenciosas e proféticas, com sua prática solidária aos sofredores e com sua tenacidade, levará adiante esse projeto de libertação. Por meio dos procedimentos exegéticos e com referencial teórico de diferentes autores que já pesquisaram sobre esse tema, pretende-se investigar a possibilidade de que neste cântico do Servo de YHWH possa nascer uma Teologia do Servo que está em profunda sintonia com o Ser do próprio YHWH. Desta maneira, YHWH - Servo carregam um mesmo projeto concreto de libertação que tem como fundamento o direito e a justiça. Surge, então, no meio do povo sofrido, um novo modelo de liderança política.

Introduction to data analysis

With the latest development in computer science, multivariate data analysis methods became increasingly popular among economists. Pattern recognition in complex economic data and empirical model construction can be more straightforward with proper application of modern softwares. However, despite the appealing simplicity of some popular software packages, the interpretation of data analysis results requires strong theoretical knowledge. This book aims at combining the development of both theoretical and applicationrelated data analysis knowledge. The text is designed for advanced level studies and assumes acquaintance with elementary statistical terms. After a brief introduction to selected mathematical concepts, the highlighting of selected model features is followed by a practice-oriented introduction to the interpretation of SPSS1 outputs for the described data analysis methods. Learning of data analysis is usually time-consuming and requires efforts, but with tenacity the learning process can bring about a significant improvement of individual data analysis skills.

Modificação do eletrodo AWS E7018 com adição de filmes finos externos de PVC e Al, para soldagem de aço C-Mn

This paper suggests modifications in coating of electrodes providing an alternative for execution of welding with low hydrogen electrode AWS E7018 without having to dry it, reducing thus the cost and time of manufacturing of high resistance welds. The welds in this research were developed with basic coated electrodes (hygroscopic) – SMAW process – externally painted with aluminum spray paint for high temperatures or wrapped with thin plastic films (PVC) and aluminum foil films used commonly for food protection. The basic premise is that establishing a barrier between the atmosphere and the electrode coating could reduce the effects of high hygroscopicity presented by coatings of low hydrogen, minimizing this way the main source of supply of hydrogen to the fusion pool during welding. It is also expected that the addition of new materials from the electrode coating to the fusion pool would induce metallurgical changes in the deposited metal and, as a consequence, modifications in its mechanical properties. This research dealt with measuring the dissolved hydrogen in the deposited metal after welding with modified electrodes, evaluating the influence of these changes in the produced microstructures and in the mechanical properties of the resulting weld, and comparing the obtained results with the standard welding procedures and with the recently developed waterproof electrodes. The results obtained in most samples welded with modified electrodes showed increased mechanical resistance and increased tenacity due to the increased percentage of acicular ferrite in metal deposited without significant elevation of hardness, when compared with the traditional welding with AWS E7018 electrode and with ELBRÁS BRH4R waterproof electrode. The diffusing hydrogen measured in the modified electrodes was kept inside the parameters defined by international codes.

Análise do comportamento reológico de pastas de cimento contendo resíduos de pneu para poços de petróleo

The low tenacity presented by the Portland cement pastes used in the oil wells cementation has been motivating several researches with attention focused on alternative materials. Additives have been developed to generate flexible pastes with mechanical resistance capable to support the expansions and retractions of the metallic covering of the wells that submit to the steam injection, technique very used to increase the recovery factor in oil reservoirs with high viscosity. A fresh paste with inadequate rheological behavior may commit the cementation process seriously, involving flaws that affect the performance of the paste substantially in the hardened state. This work proposes the elaboration and the rheological analysis of Portland cement pastes with addition of residues of rubber tire in several proportions, with the aim of minimizing the damages provoked in the hem cementing of these wells. By thermogravimetric analysis, the particles of eraser that go by the sieve of 0,5mm (35 mesh) opening and treated superficially with NaOH solution of 1 mol/L presented appropriate thermal resistance for wells that submit to thermal cyclic. The evaluation of the study based on the results of the rheological analysis of the pastes, complemented by the mechanical analysis, thickening, stability, tenor of free water and filtrate loss, being used as parameter a paste reference, without rubber addition. The results showed satisfactory rheology, passive of few corrections; considerable loss of mechanical resistance (traction and compression), compensated by earnings of tenacity, however with established limits for its application in oil wells; satisfactory stability, free water and thickening time

Whose health, whose care, whose say? Some comments on public involvement in new NHS commissioning arrangements

Recent health policy in England has demanded greater involvement of patients and the public in the commissioning of health and social care services. Public involvement is seen as a means of driving up service quality, reducing health inequalities and achieving value in commissioning decisions. This paper presents a summary and analysis of the forms that public involvement in commissioning are to take, along with empirical analysis from a qualitative study of service-user involvement. It is argued that the diversity of constituencies covered by the notion of ‘public involvement’, and the breadth of aims that public involvement is expected to achieve, require careful disaggregation. Public involvement in commissioning may encompass a variety of interest groups, whose inputs may include population needs assessment, evaluation of service quality, advocacy of the interests of a particular patient group or service, or a combination of all of these. Each of these roles may be legitimate, but there are significant tensions between them. The extent to which the structures for public involvement proposed recognize these possible tensions is arguably limited. Notably, new Local Involvement Networks (LINks), which will feed into commissioning decisions, are set as the arbiters of these different interests, a demanding role which will require considerable skill, tenacity and robustness if it is to be fulfilled effectively.

Influência da adição de gres porcelanato no comportamento mecânico e microestrutural em pastas de cimento portland para cimentação de poços de petróleo

Cementation operation consists in an extremely important work for the phases of perforation and completion of oil wells, causing a great impact on the well productivity. Several problems can occur with the cement during the primary cementation, as well as throughout the productive period. The corrective operations are frequent, but they are expensive and demands production time. Besides the direct cost, prejudices from the interruption of oil and gas production till the implementation of a corrective operation must be also taken into account. The purpose of this work is the development of an alternative cement paste constituted of Portland cement and porcelainized stoneware residue produced by ceramic industry in order to achieve characteristics as low permeability, high tenacity, and high mechanical resistance, capable of supporting various operations as production or oil wells recuperation. Four different concentration measures of hydrated paste were evaluated: a reference paste, and three additional ones with ceramic residue in concentrations of the order of 10%, 20% and 30% in relation to cement dough. High resistance and low permeability were found in high concentration of residues, as well as it was proved the pozolanic reactivity of the residue in relation to Portland cement, which was characterized through x-ray and thermogravimetry assays. It was evident the decrease of calcium hydroxide content, once it was substituted by formation of new hydrated products as it was added ceramic residue

Efeito da adição de microfibras de lã de vidro na tenacidade à ruptura de pastas de cimento para poços de petróleo

Although there are a wide variety of additives that act in fresh state, to adjust the properties of cement, there is also a search by additions that improve the tenacity of the cement in the hardened state. This, in turn, can often be increased by inserting fibers, which act on the deflection of microcracks. This study aimed to use a microfiber glass wool (silica-based) as an additive reinforcing the cement matrix, improving the rupture tenacity, in order to prevent the propagation of microcracks in the cement sheath commonly found in oil wells submitted to high temperatures. The fibers were added at different concentrations, 2 to 5% (BWOC) and varied average sizes, grinding for 90 s, 180 s, 300 s, 600 s. The cement slurries were made with a density of 1,90 g/ cm3 (15,6 lb/gal), using Portland cement CPP- Special Class as the hydraulic binder and 40% silica flour. The characterization of the fiber was made by scanning electron microscopy (SEM), particle size by sieving, X-ray fluorescence (XRF), X-ray diffraction (XRD) and thermogravimetry (TG / DTG). Were performed technological tests set by the API (American Petroleum Institute) by rheology, stability, free water, compressive strength, as well as testing rupture energy, elastic modulus and permeability. The characterization results showed good thermal stability of the microfiber glass wool for application in oil wells submitted to steam injection and, also, that from the particle size data, it was possible to suggest that microfibers milled up to 300 s, are ideal to act as reinforcement to the cement slurries. The rheological parameters, there was committal of plastic viscosity when larger lengths were inserted of microfiber (F90). The values obtained by free water and stability were presented according to API. The mechanical properties, the incorporation of microfiber to the cement slurries gave better rupture tenacity, as compared to reference cement slurries. The values of compressive strength, elastic modulus and permeability have been maintained with respect to the reference cement slurries. Thus, cement slurries reinforced with microfiber glass wool can ensure good application for cementing oil wells submitted to steam injection, which requires control of microcracks, due to the thermal gradients

The influence of neoconservatism on US foreign policy debates during the Obama administration

Neoconservatism reached its zenith as a school of thought when it became associated with the Iraq War. Although the war was largely considered a failure, it raised the profile of neoconservatism as a school of thought. Many studies were completed which pointed to the influence of prominent members of the George W. Bush administration who were considered to be ideologically neoconservative. When Obama won the presidency in 2008, it was assumed that the influence of neoconservatives, or neoconservatism more broadly, would be over. However, given neoconservatism’s historical foundations and the tenacity of its adherents it seemed important to consider whether this has been the case. Therefore, this thesis set out to answer the question: To what extent have neoconservatives, and neoconservatism more broadly, influenced foreign policy debates during the Obama administration? I argue that neoconservatism has remained not only salient within foreign policy debates, but prominent in these debates, during Obama’s two terms in office. An examination of US foreign policy towards the nuclear crisis in Iran and the Syrian civil war indicates that neoconservatism had a substantive influence on the policy debates and the options considered within them, particularly in Congress. In some instances, neoconservative policy entrepreneurs contributed to legislation. Furthermore, this thesis finds that neoconservatism has been the predominant approach to foreign policy within the Republican Party on the issues of Iran and Syria during the period under review.
