De repente, tudo mudou de lugar: refletindo sobre metamorfose urbana e gentrificação em Mossoró-RN

This study aims at solidifying the theoretical bases to provide, above all, an explanation for this phenomenon which currently happens, with a scenario of social, political, economic and cultural transformations worldwide in medium cities. Nevertheless, because it has different dimensions from its transformation axes, gentrification comes with change, but also with the introduction of a new purpose in the space using and occupation, outlining in this context the identity of places from the formation of centralities with the presence of flows with social and economic dynamicsThe current forms of geographic space appropriation show the directions of the senses and ideological profile which recreates the meanings and uses of content and materials from descriptions of a historical past. However, today there is an economic context in the urban space which refers to a search of strategies for change, i.e., the acquisition of parameter aimed at meeting the demands of the relationship between capital and labor, which ends up overriding some actions for the specification of the transformation methods within the urban space to be explained by new needs and also by the agents from the value adding to their interests and investments. Thus, we assume that the appreciation/gentrification of urban spaces may or may not result from the building of a public space, since the dialogic structure as a place of political interaction externalize conflicts and disagreements in general; it keeps segregating spaces. As new spaces are transformed, the access to them tends to happen with particular restriction, whereas some places like parks, shopping malls, high-rise and horizontal condos are the scene for major professional and family events. In this context, the gentrification process is used to designate interventions in the urban environment, in certain city spaces which are considered central to public and private investments. A historical place is permitted to be presented as a scenario, a stage full of attractions, through the transformation process. Studying gentrification consists of an analysis of the underlying interests in the transformation of these areas, and especially of the assessment of the interest level in the private sector to partner in order to modify the landscape. Gentrification results from the transformation processes of capital, which influences the efforts and investments application in order to establish and achieve optimal economic growth, focusing on a location socio-culturally centered in the urban space. Thus, the urban social structure develops in the light of some questions that relate not only the cities growth but also environmental conditions it provides in cities like Mossoro, State of Rio Grande do Norte, Brazil 2005 a 2011.

Arquitetura e patrimônio no ensino de história: uma leitura a partir da igreja Nossa Senhora do Carmo

A presente investigação se insere na linha de pesquisa História, pesquisa e vivências de ensino aprendizagem. Buscamos defender a ideia de que o estudo da Educação Patrimonial através da arquitetura se constitui como campo de possibilidades para a (re) significação do ensino de História e da compreensão da história local e, por conseguinte da história de cada indivíduo. A pesquisa justifica-se em virtude da relevância que os bens arquitetônicos têm a contribuir no ensino de História, no entendimento dos processos de mudanças e transformações pelos quais passa o local que esta se encontra. Suas modificações estruturais, usos e desusos são como páginas escritas e expostas a céu aberto, para todo aquele que queira observar e investigar o possa e o faça. Ressaltamos a utilização da abordagem de cunho qualitativo, com foco nos processos apresentados na metodologia da Educação Patrimonial, difundida no Brasil por Horta, sendo a presente investigação uma possibilidade que se integra aos já conhecidos caminhos que percorrem as atividades de Educação Patrimonial nas escolas. A partir da pesquisa histórica acerca da Igreja do Carmo, bem arquitetônico do Rio Grande, desenvolveram-se oficinas patrimonias com 35 alunos do Ensino Fundamental II, a fim de que os objetivos propostos através da educação patrimonial fossem alcançados e por fim disponibilizar a educadores e pesquisadores da área, os resultados, a pesquisa e o material paradidático elaborado a partir das ações da pesquisa.

Relatos biográficos de professores/educadores de adultos: a ação das coordenações concelhias no âmbito do plano integrado de desenvolvimento regional (PIDR) do nordeste algarvio

Esta investigação é centrada nos discursos produzidos por oito professoras que atribuíram sentidos à sua vida e contribuíram para construção de conhecimento sobre a educação de adultos, no contexto do projeto integrado de desenvolvimento regional do nordeste algarvio, na década de 80. Os relatos biográficos revelaram formas e sentidos múltiplos sobre as várias transições biográficas em que as professoras construíram novas identidades de aprendizagem, integraram novos saberes e viveram diferentes contextos de interação humana. A investigação também permitiu caracterizar as diferentes experiências e práticas educativas no campo da educação de adultos. Decorrente das conclusões, damos o nosso contributo através de uma proposta que consideramos estratégica para a reconfiguração e revalorização de uma educação de adultos de raiz humanista e democrática, para todas as pessoas, por forma a provocar a mudança na sociedade em que todos devem ser sujeitos ativos e comprometidos com a transformação social; ABSTRACT: Biographical Accounts of Teachers I Adult Educators This investigation is focused on the discourses produced by eight teachers who gave meanings to their lives and contributed to the building of knowledge on adult education, within the project of regional development of the northeast Algarve, during the 80s of the XX century. Their biographical accounts revealed the multiple senses on the various biographical transitions in which teachers built new learning identities, integrated new knowledge and lived different contexts of human interaction. This research also allowed to characterize the different experiences and educational practices in the field of adult education. As a consequence of the conclusions, we built a strategic proposal towards the reshaping and revaluing of adult education. This is a proposal to achieve a concept of democratic adult education inspired in the humanist paradigm, which tries to foster societal change, in which all should be active citizens engaged with social transformation processes.

GENERATIVE LEADERSHIP

This article presents the results of a research project that studied leadership from the standpoint of the personal conceptions that influence the behavior of local government leaders, as well as those conceptions desired to generate the social transformation processes required in communities. Qualitative methodology was used. Categories of analysis were created based on Pearson’s (1992) model of psychological archetypes. A relevant finding was the limited advance shown by interviewees regarding self-knowledge and a fragmented vision between the observer and the observee, which hinders their ability to take on the challenges that current reality demands from them.

Do improved pastures affect enzymatic activity and C and N dynamics in soils of the montado system ?

Vast montado areas are threatened by degradation, as the result of a long history of land use changes. Since improved pastures have been installed aiming soil quality improvement and system sustainability, it is crucial to evaluate the effects of these management changes on soil organic matter status and soil biological activity, as soil quality indicators. Therefore, a 35-yr old improved pasture and a natural pasture were studied, considering areas beneath tree canopy and in the open. Total organic C, total N, hot water soluble (HWS) and particulate (POM) C, microbial biomass C (MBC) and N (MBN), C mineralization rate (CMR) and net N mineralization rate (NMR) were determined. In addition, for a 1-yr period, soil β-glucosidase, urease, proteases and acid phosphomonoesterase were periodically determined. Improved pasture promoted the increase of soil C and N through POM-C increment, particularly beneath the trees canopies. The two study pastures did not show differences regarding soil microbial biomass, but variations in CMR, HWS-C and N availability (proteases and urease activities) suggest divergent soil microbial communities. Tree regulator role on C, N and P transformation processes in soil was confirmed

Emergence and fate of siloxanes in waste streams: Release mechanisms, partitioning and persistence in three environmental compartments

Siloxanes are widely used in personal care and industrial products due to their low surface tension, thermal stability, antimicrobial and hydrophobic properties, among other characteristics. Volatile methyl siloxanes (VMS) have been detected both in landfill gas and biogas from anaerobic digesters at wastewater treatment plants. As a result, they are released to gas phase during waste decomposition and wastewater treatment. During transformation processes of digester or landfill gas to energy, siloxanes are converted to silicon oxides, leaving abrasive deposits on engine components. These deposits cause increased maintenance costs and in some cases complete engine overhauls become necessary. ^ The objectives of this study were to compare the VMS types and levels present in biogas generated in the anaerobic digesters and landfills and evaluate the energetics of siloxane transformations under anaerobic conditions. Siloxane emissions, resulting from disposal of silicone-based materials, are expected to increase by 29% within the next 10 years. Estimated concentrations and the risk factors of exposure to siloxanes were evaluated based on the initial concentrations, partitioning characteristics and persistence. It was determined that D4 has the highest risk factor associated to bioaccumulation in liquid and solid phase, whereas D5 was highest in gas phase. Additionally, as siloxanes are combusted, the particle size range causes them to be potentially hazardous to human health. When inhaled, they may affix onto the alveoli of the lungs and may lead to development of silicosis. Siloxane-based COD-loading was evaluated and determined to be an insignificant factor concerning COD limits in wastewater. ^ Removal of siloxane compounds is recommended prior to land application of biosolids or combustion of biogas. A comparison of estimated costs was made between maintenance practices for removal of siloxane deposits and installation/operation of fixed-bed carbon absorption systems. In the majority of cases, the installation of fixed-bed adsorption systems would not be a feasible option for the sole purpose of siloxane removal. However they may be utilized to remove additional compounds simultaneously.^

Processes of transformation : art into pop and back again

This research project was a case study for managing and innovating an interdisciplinary practice: specifically across music, performance and contemporary art. Key works included painting/sound/video installation, experimental performance, electronic pop music, music video and electronic pop music performance. An idiosyncratic and transformative use of colour emerged as an underlying theme and strategy for cohesion. The project offers strategies for the challenges of interdisciplinary practice specifically addressing the limitations related to institutionalised value systems, aesthetic traditions and disciplinary languages.

Non-agrocultural co-peratives and economy transformation in Cuba: politic processes and strategies

Contribution of co-operatives has been demonstrated since the 1970s as the main development line in agricultural production in Cuba. In contrast, there has been a late recognition of urban co-operatives, even if the need of transformations based on the realization of property in different territorial scenarios had been identified. The article analyses the reform processes launched since the first decade of the 21st century focusing on the nature of the initiatives fostering formation and promotion of nonagricultural co-operatives including follow up of their performance. The potential and limitations of the recent experiences are examined in order to reflect on the organizational processes and transformations from the point of view of their members. To conclude, some questions are posed about whether these co-operatives are capable of avoiding the impact of earlier employment circumstances and of developing strategies aimed at reinforcing voluntary membership and autonomy on which they are founded.

Catalytic processes for the transformation of ethanol into acetonitrile

This thesis deals with the transformation of ethanol into acetonitrile. Two approaches are investigated: (a) the ammoxidation of ethanol to acetonitrile and (b) the amination of ethanol to acetonitrile. The reaction of ethanol ammoxidation to acetonitrile has been studied using several catalytic systems, such as vanadyl pyrophosphate, supported vanadium oxide, multimetal molibdates and antimonates. The main conclusions are: (I) The surface acidity must be very low, because acidity catalyzes several undesired reactions, such as the formation of ethylene, and of heavy compounds as well. (II) Supported vanadium oxide is the catalyst showing the best catalytic behaviour, but the role of the support is of crucial importance. (III) Both metal molybdates and antimonates show interesting catalytic behaviour, but are poorly active, and probably require harder conditions than those used with the V oxide-based catalysts. (IV) One key point in the reaction network is the rate of reaction between acetaldehyde (the first intermediate) and ammonia, compared to the parallel rates of acetaldehyde transformation into by-products (CO, CO2, HCN, heavy compounds). Concerning the non-oxidative process, two possible strategies are investigated: (a) the ethanol ammonolysis to ethylamine coupled with ethylamine dehydrogenation, and (b) the direct non-reductive amination of ethanol to acetonitrile. Despite the good results obtained in each single step, the former reaction does not lead to good results in terms of yield to acetonitrile. The direct amination can be catalyzed with good acetonitrile yield over catalyst based on supported metal oxides. Strategies aimed at limiting catalyst deactivation have also been investigated.

ERP Software Selection Processes: A Case Study in the Metal Transformation Sector

When a firm decides to implement ERP softwares, the resulting consequences can pervade all levels, includ- ing organization, process, control and available information. Therefore, the first decision to be made is which ERP solution must be adopted from a wide range of offers and vendors. To this end, this paper describes a methodology based on multi-criteria factors that directly affects the process to help managers make this de- cision. This methodology has been applied to a medium-size company in the Spanish metal transformation sector which is interested in updating its IT capabilities in order to obtain greater control of and better infor- mation about business, thus achieving a competitive advantage. The paper proposes a decision matrix which takes into account all critical factors in ERP selection.
