Intraplate earthquake swarm in Belo Jardim, NE Brazil: reactivation of a major Neoproterozoic shear zone (Pernambuco Lineament)

Intraplate earthquakes in stable continental areas have been explained basically by reactivation of pre-existing zones of weakness, stress concentration, or both. Zones of weakness are usually identified as sites of the last major orogeny, provinces of recent alkaline intrusions, or stretched crust in ancient rifts. However, it is difficult to identify specific zones of weakness and intraplate fault zones are not always easily correlated with known geological features. Although Northeastern Brazil is one of the most seismically active areas in the country (magnitudes 5 roughly every 5 yr), with hypocentral depths shallower than similar to 10 km and seismic zones as long as 30-40 km, no clear relationship with the known surface geology can be usually established with confidence, and a clear identification of zones of weakness has not yet been possible. Here we present the first clear case of seismic activity occurring as reactivation of an old structure in Brazil: the Pernambuco Lineament, a major Neoproterozoic shear zone. The 2004 earthquake swarm of Belo Jardim (magnitudes up to 3.1) and the recurrent activities in the nearby towns of Sao Caetano and Caruaru (magnitudes up to 4.0 and 3.8), show that the Pernambuco Lineament is a weak zone. A local seismic network showed that the Belo Jardim swarm of 2004 November occurred by normal faulting on a North dipping, E-W oriented fault plane in close agreement with the E-W trending structures within the Pernambuco Lineament. The Belo Jardim activity was concentrated in a 1.5 km (E-W) by 2 km (downdip) fault area, and average depth of 4.5 km. The nearby Caruaru activity occurs as both strike-slip and normal faulting, also consistent with local structures of the Pernambuco Lineament. The focal mechanisms of Belo Jardim, Caruaru and S. Caetano, indicate E-W compressional and N-S extensional principal stresses. The NS extension of this stress field is larger than that predicted by numerical models such as those of Coblentz & Richardson and we propose that additional factors such as flexural stresses from the nearby Sergipe-Alagoas marginal basin could also affect the current stress field in the Pernambuco Lineament.

MODELING THE EVOLUTION OF COMPLEX NETWORKS THROUGH THE PATH-STAR TRANSFORMATION AND OPTIMAL MULTIVARIATE METHODS

The topology of real-world complex networks, such as in transportation and communication, is always changing with time. Such changes can arise not only as a natural consequence of their growth, but also due to major modi. cations in their intrinsic organization. For instance, the network of transportation routes between cities and towns ( hence locations) of a given country undergo a major change with the progressive implementation of commercial air transportation. While the locations could be originally interconnected through highways ( paths, giving rise to geographical networks), transportation between those sites progressively shifted or was complemented by air transportation, with scale free characteristics. In the present work we introduce the path-star transformation ( in its uniform and preferential versions) as a means to model such network transformations where paths give rise to stars of connectivity. It is also shown, through optimal multivariate statistical methods (i.e. canonical projections and maximum likelihood classification) that while the US highways network adheres closely to a geographical network model, its path-star transformation yields a network whose topological properties closely resembles those of the respective airport transportation network.

När lanthandeln stänger : En studie av lanthandelns betydelse för flyttning in och ut och för människorna i byn

In Sweden the number of rural food shops has decreased for more than 50 years. Often the closing of a village shop is supposed to affect the migration patterns in the area it has been serving. However, according to this study, neither in- nor out-migration in the area affected by the closing is affected. The deficits of migration usual in those areas are established at least 10-12 years before the closing year. Thus, the typical closing takes place subsequent to a long term population decline. On the other hand, localities hosting a shop that survived during the study period 1990-2004 have a bigger total population and show tendencies towards decreasing deficit of migration at any potential closing year. These statistical results are supported by interviews carried out in three villages where the last shop has closed. They indicate that the shop has already lost its importance as supplier when it closes. By then the village shop is primarily used as complement to nearby towns or shopping centres. Each of the two studies accounted for here point at a relative un-importance of the village shop as a service point at the closing time. However, as it often offer the last public space in the village the village shop serves a key function as a meeting point for some households. When the shop has closed, the village holds private homes only. That is a situation increasing loneliness to some inhabitants.

Strategic alliances in a town centre : Stakeholder’s perceptions of property owner’s role

In order for town centres to manage increased competition in retailing, co-operation between stakeholders in a strategic alliance has become more important. A typical set of stakeholders in a strategic alliance for strengthening retailingare retailers, local authorities and property owners. The roles of retailer’sand local authorities’ are well researched. However, the role of property owners is not. The aim of this paper seeks to unfold the role of property owners in a strategic alliance. This is a case study of a medium-sized town in which semi-structured interviews with different stakeholders were conducted. In the chosen town there is a TCM alliance co-operation at work. The above mentioned stakeholders are possible members in an alliance. The case studied shows a fragmented property owner market with no dominant property owner, as it is in many medium-sized towns. Our study shows that many stakeholders look at the role of property owners as crucial for town centre development. However, property owners do not see that they can significantly contribute to or benefit from the development.The main reasons for this opinion are that they consider themselves as not having enough resources or the capability to influence the town development.

The effects of Ikea and external shopping centers on regional trade and retail growth : A comparative analysis of Ikea’s establishment in Kalmar and Karlstad

This paper examines the effects of Ikea store establishment in Kalmar and Karlstad on the trade and retail inside the two cities, and as well on the trade and retail in the close neighboring municipalities and in further peripheral municipalities in both regions. After the establishment of Ikea store, Kalmar and Karlstad have experienced significant growth in trade and retail. The question, however, is how big this growth is in both cities? And how different locations on different distances from Ikea have been affected? What impact there was on different segments of the retail? How different business branches have been affected? How large the catchment area for the emerging new large-scale retail locations is? These questions, in addition to few others, are investigated in this paper. The thesis starts with an introduction chapter containing a background of the topic, problem description, the investigated questions, the purpose, and the outline of the paper. The next chapter includes the frame of reference which consists of literature review and theoretical framework about the external shopping centers and their impact on retail and regional trade development. It includes also information gathered from previous studies technical reports and other available sources about the subject. The third chapter includes description for the methods used to collect the primary and secondary data needed for the purpose of this study. Then the empirical framework which demonstrates the results of the conducted research followed by analysis and concluded in discussion and conclusion. Mixed methods are used as research strategy in this thesis, and the method to conduct the research is based on telephone interviews for the primary (qualitative) data, and documents and desk research for the secondary (quantitative) data. The gathered data is analyzed and designed in a way that allows the usage of comparative analysis technique to present the findings and draw conclusions. The results showed that new established Ikea retail store outside the city boundaries results with many effects on the city center and on the neighboring municipalities as well. The city center seems not to be affected negatively, but on the contrary positive effects were witnessed in both regions, these positive effects are linked to the increase inflow of customers from the external retail area which is known as spillover effect. III On the other hand, the neighboring towns and municipalities are more negatively affected especially with the trade of con-convenience goods as the consumers in these towns and municipalities start to go to the area of Ikea and the large external retail center to do their purchasing, the substitution effect is then said to be occurred. Moreover, the further far municipalities do not seem to be significantly affected by the establishment of Ikea. These effects whether positive or negative could be monitored by looking to few trade parameters such as the turnover, the sales index, and the consumers’ expenditure, these parameters can be very useful to measure the developments and changes in the trade and retail in a given place. 

The Impact of Land Use Patterns and Watershed Characteristics on China Lake, Kennebec County, Maine

China Lake is located in Kennebec County, Maine. Since 1983 the lake has suffered from yearly algal blooms as a result of the addition of excess nutrients. The nutrient load was amplified by erosion within the watershed. Erosion varies widely depending on a number of factors, including the slope of the land, the type of soil, and the way the land is being used. Certain land use types have a high potential to add nutrients to the environment, while others may help absorb excess nutrients and prevent erosion and runoff into the lake. A comprehensive examination of the China Lake watershed was completed using GIS to calculate the erosion potential for the entire area, taking into account past and present land use patterns. This information will help the towns around the lake to make informed decisions about future development and land management.

Prioritizing Land Purchases for the Belgrade Regional Conservation Alliance

The Belgrade Regional Conservation Alliance is an organization that is dedicated to preserving land and water quality in the Belgrade Lakes region in Maine. The BRCA holds land in such towns as Belgrade, Mount Vernon, New Sharon, Vienna, Rome, Smithfield, and Oakland. The BRCA is looking to expand its acreage in and around these areas to better accommodate the public and to promote the ongoing effort to conserve land as part of the Kennebec Highlands Project. The BRCA is currently considering parcels of 50+ acres in New Sharon, Rome, Belgrade, and Mount Vernon. In order to identify possible suitable parcels, we completed a GIS analysis and produced these layered maps, which highlight areas of land that we think might be desirable to the BRCA. Our analysis encompasses human access, wildlife access, and the locations and sizes of parcels.

O outro lado de cá: histórias e memórias de Cachoeira da Prata

O principal objetivo dessa dissertação é analisar, através de um estudo caso, como a questão do “preconceito intergrupal” pode ser percebida no desenvolvimento histórico de pequenos municípios brasileiros. Escolhendo a história da memória da cidade de Cachoeira da Prata como objeto central, buscamos discutir como ocorreu o processo de diferenciação social da pequena comunidade formada pelos descendentes do ex-escravo Nicolau Teixeira do restante da cidade. Para tanto, dividimos a dissertação em duas partes. A primeira é formada pelos três primeiros capítulos, nos quais apresentamos a vila fabril de Cachoeira de Macacos como o cenário, no qual o cel. Américo Teixeira é identificado como o líder maior de um projeto de domínio político e industrial que deixou marcas duradouras na memória da população mais antiga da cidade. Nesse contexto, buscamos discutir como o fenômeno do pós-emancipação da escravidão se manifestou na localidade, analisando parte da trajetória de vida do ex-escravo Nicolau Teixeira, um leal apoiador do projeto político do cel. Américo, que se tornou, na primeira metade do século XX, o patriarca de uma comunidade criada nas imediações da antiga vila fabril. Na segunda parte, composta exclusivamente pelo quarto capítulo, discutimos de maneira conjugada, a história da diferenciação social da comunidade e diferentes posicionamentos políticos e metodológicos que adotamos ao longo da pesquisa. Após essa análise, concluímos que só é possível entender os meandros do processo que levou os descendentes de Nicolau Teixeira à condição de exclusão social após percebê-los como atores capazes de elaborar narrativas e representações que auxiliam a população de Cachoeira da Prata a conhecer um “outro lado” da história local.

Qualidade de vida e transporte público urbano: estratégias para melhorar a qualidade do serviço de transporte público urbano por ônibus

If urban planning is to support the equitable distribution of public goods and services, it must recognize and address the dismal condition of millions of poor people who are living in a city. The primary focus of contemporary planners and planning students should be on finding and advocating solutions that help eliminate the problems of today¿s cities. Any meaningful solution will need to be grounded in a thorough understanding of the social class inequities of citizens. With the rapid development of national economy and urbanization process in Brazil over the last two decades, the number of vehicles and their travels are dramatically increased. This is particularly evident in all large cities. Traffic congestion becomes more and more severe. Inadequate parking facilities often result in difficulty to find a parking space in large cities and many illegally parked vehicles can be seen on the crowed streets. These illegally parked vehicles further intensify traffic congestion and also pose a traffic safety hazard. The process of urbanization and motorization in Brazil is likely to continue in a rapid pace. The urban public passengers transport modes problems in large cities are likely to get even worse. There is an urgent need for the development of policy and criteria for public service of urban public passenger transport by bus in large cities. The purpose of survey is to develop policy guidelines for public transport services planning, design, construction and mobility management, that meet community needs for accessibility in large cities. So this thesis will present major comparative characteristics of urban mobility management, urban public passengers transport by bus services planning and the quality of social life in two towns of Brazil: Rio de Janeiro and Curitiba. The study case has been focused on Rio de Janeiro and Curitiba because of the major different results of the survey presented by the two cities. The objectives of this thesis are: a) to analyze and discus existing urban mobility related accessibility and economic development problems in large cities; b) to provide an overview of the relationship within city ¿ quality of social life ¿ urban mobility in Rio and Curitiba; c) to analyze and discuss existing urban mobility management related public transport services in Rio and Curitiba; d) to analyze and discuss existing quality of bus public transport services problems in Rio. Some preliminary recommendations for mobility management policies will also be presented.

Desenvolvimento local, cidadania e redes sociais: um estudo em Minas Gerais

The objective of this essay was to verify if the practices of local development in these small towns (population under 20.000 inhabitants) of Lavra¿s small region have contributed to the formation and/or strengthening of social network. The work was conducted from a theoretical discussion about local development, citizenship, local development with citizenship and social network. Afterward interviews were made semi-structured with a sample formed of 54 citizens of six towns of Lavra¿s small region in Minas Gerais. The speech analysis was used in the treatment of the dates. As results, considering the strengthening and formation of social network, it is possible to say: about the strengthening, that there is not a possibility, because the social networks structured as we understand it, do not exist or are still to embryonic, prevailing, in the formation towns, the pyramidal structure. And about the formation, it is notable that there are more negative aspects than positive to the development of these networks, however some initiative point out to the possibilities of creation. Therefore, we can conclude that the practice of local development contribute, still, in a very incipient and limited manner to the formation of social networks in the state¿s town. Incipient because the identified initiatives that points towards the creation are recent and are still in a structure stage; and limited because there are too many negative aspects that make the construction difficult.

Ciclos políticos nos municipios brasileiros: interação entre o governo municipal e as demais esferas de governo através das transferências voluntárias

Este trabalho analisa a interação entre o prefeito e as outras esferas do executivo nacional através das transferências voluntárias e as implicações nas contas públicas. É notória a utilização das transferências voluntárias como canal político; há aumento destas receitas tanto nos anos de eleição para prefeito quanto governador e presidente. O impacto das transferências voluntárias é significativo para diferenciar as despesas, investimento e gastos sociais, entre os municípios. Assim, como contrapartida, o governo municipal aumenta os gastos tanto nos anos do fim do mandato quanto no período do meio de mandato. As estimações sugerem que os gastos são estatisticamente maiores nas eleições para presidente e governador do que para o ciclo eleitoral do prefeito. Entretanto, o resultado para as receitas municipais apresenta um comportamento diferente dos gastos. As transferências voluntárias normalmente não explicam as diferenças de arrecadação municipal. Nos anos eleitorais para presidente e governador não há redução da arrecadação dos tributos municipais, o que já ocorre no final do mandato dos prefeitos. As estatísticas mostram que para as despesas há ciclo tanto no meio quanto no final do mandato, no entanto para as receitas há prioridade para as eleições municipais. Utilizamos um painel não balanceado para todos os municípios brasileiros, que havia informação, no período de 1996-2004.

A robust poverty profile for Brazil using multiple data sources

This paper presents a poverty profile for Brazil, based on three different sources of household data for 1996. We use PPV consumption data to estimate poverty and indigence lines. “Contagem” data is used to allow for an unprecedented refinement of the country’s poverty map. Poverty measures and shares are also presented for a wide range of population subgroups, based on the PNAD 1996, with new adjustments for imputed rents and spatial differences in cost of living. Robustness of the profile is verified with respect to different poverty lines, spatial price deflators, and equivalence scales. Overall poverty incidence ranges from 23% with respect to an indigence line to 45% with respect to a more generous poverty line. More importantly, however, poverty is found to vary significantly across regions and city sizes, with rural areas, small and medium towns and the metropolitan peripheries of the North and Northeast regions being poorest.

Lazer : a perspectiva dos moradores no município de Duque de Caxias - RJ

Esta dissertação objetiva-se a pesquisar o padrão de escolha dos moradores de Duque de Caxias em relação à oferta de produtos e serviços de lazer disponíveis no município e na região metropolitana da cidade do Rio de Janeiro. Considerando a relação cidade, cidadania e qualidade de vida, no caso do município de Duque de Caxias, periferia da Região Metropolitana – RJ verifica-se a indisponibilidade de equipamentos urbanos e ausência de ordenamento territorial capaz de suprir as necessidades humanas da população local. O desenvolvimento econômico no município ocasionou o processo de implantação de complexos industriais na região, acelerando o fenômeno da urbanização e criando grande déficit na oferta de políticas públicas como segurança, saúde e serviços de lazer aos seus moradores. Por meio de aplicação de pesquisa de campo, através do acesso a mídia interativa, foram entrevistados vinte moradores do município sobre suas preferências e hábitos relacionados ao lazer. Com base na técnica da análise de conteúdo, verificou-se que para os entrevistados as atividades de lazer que buscam dentro do próprio município em que residem estão principalmente ligadas aos interesses sociais. Em relação às opções relacionadas a boates e restaurantes, o pequeno número de opções disponíveis ao morador, por melhores que sejam quanto à qualidade, fazem com que busquem em cidades próximas. Entende-se ainda, que se fazem necessário que se invista em opções de lazer de qualidade e voltado para o lazer intelectual, já que são quase inexistentes.
