O processo de urbanização de Mossorò: dos processos históricos à estrutura urbana atual

The general objective of this academic work is to analyze the relationship between the territorial division and the urban expansion process of Mossoró city, understood here as the production and occupation of space. The urban expansion in Mossoró, since its formation as settlement in 1772 until current days, identifies with the Brazilian urbanization process whose growth is determined by the capitalist development. Thus, the expansion was determined by several economical specializations imposed by the territorial division of work which occurs at an interregional level, and, sometimes at an international level. Then, each specialization determined a moment of the urban expansion of the city, as follows: a) The cattle farmer specialization, between 1772 and 1857, when the urban expansion was shy, is summarized to a commercial square that received goods from Aracati aiming to cover a wide rural area; b) The commercial emporium specialization, between 1857 and 1930, when the urban expansion took an important impulse with the concentration of public and private capitals; c) The salt industry and the agricultural-industrial exporter specialization inside a state of development policy, between 1930 and 1970, when the urban expansion, joined to the settlement of the working class in the urban soil, developed along an important axis -the railway; d) The render of services specialization inside a state of intervention policy, between 1970 and 1990, when the urban expansion was characterized by the accelerated growth rhythm, by the reuse of some spaces, and by space segregation of demanding people; e) The render of services policy inside a neoliberal state policy, since 1990 until current days, when the urban expansion reduced its rhythm abruptly, when only small alterations occurred in the existing spaces. It focused on social policies and on several slums eradication programs. Finally, the territorial structure is deeply articulated with others, no territorial, but economical, social and political, which happens at a national, regional and local rate. Only within a historical and conceptual panorama, it was possible to explain the urban expansion in Mossoró from its formation in 1772 until current days. Therefore, this work is a several discipline analysis of the urbanization process existing in Mossoró

Exporting the racial republic: African colonization, national citizenship, and the transformation of U.S. expansion, 1776-1864

The effort to create a colony of African Americans on the west coast of Africa was one of the most celebrated and influential movements in the United States during the first half of the 19th century. While historians have often viewed African colonization through the lens of domestic anti-slavery politics, colonization grew from an imperial impulse which promised to transform the identities of black colonists and indigenous Africans by helping them to build a democratic nation from the foundation of a settler colony. By proposing that persons of African descent could eventually become self-governing subjects, the liberal framework behind colonization offered the possibility of black citizenship rights, but only within racially homogenous nation-states, which some proponents of colonization imagined might lead to a “United States of Africa.” This dissertation examines how the notion of expanding democratic ideals through the export of racial nationhood was crucial to the appeal of colonization. It reveals how colonization surfaced in several crucial debates about race, citizenship, and empire in the antebellum United States by examining discussions about African Americans’ revolutionary claims to political rights, the bounds of US territorial expansion, the removal of native populations in North America, and the racialization of national citizenship, both at home and abroad. By examining African colonization from these perspectives, this dissertation argues that the United States’ efforts to construct a liberal democracy defined by white racial identity were directly connected to the nation’s emerging identity as a defender and exporter of political liberty throughout the world.

Aspectos econômicos da produção de bovinos de corte

O Brasil ocupa as posições de maior produtor e exportador mundial de carne bovina, com a região Centro-Oeste respondendo por 35% do abate nacional, em 2010. Entretanto, faz-se necessário valorizar o planejamento, o controle e a gestão empresarial nas propriedades produtoras, visando ao lucro na atividade. O presente estudo objetivou analisar e avaliar a viabilidade econômica da produção de bovinos de corte, em Camapuã (MS), a fim de identificar os itens relevantes aos custos da atividade. Como direcionador dos custos variáveis, no custo operacional efetivo, o suplemento mineral fornecido aos animais e a mão de obra mostraram-se relevantes para a gestão do sistema de produção, representando, aproximadamente, 71% dos custos. Com base nos resultados apresentados, pôde-se concluir que a propriedade apresenta boa lucratividade (superior a 20%). Verificou-se, ainda, com base no fluxo de caixa, taxa interna de retorno de 13,13% e capital inicial investido retornando em, aproximadamente, 7 anos, com resultados atrativos para o investimento, neste segmento agropecuário. O estudo proporcionou um parâmetro de custo para o produtor pecuarista, podendo contribuir para um melhor planejamento de atividades, em que, apesar dos altos investimentos iniciais, possivelmente, poderá reduzir seus custos, com o manejo racional no sistema produtivo, o que seria mais atrativo para o mercado, tornando mais viáveis as suas atividades de produção e comercialização do produto.

Health tourism trends in the United Kingdom: Are they net exporters of health services?

The study investigates the inbound and outbound health tourism in the United Kingdom (UK) to determine if the UK can be considered as a net exporter of health services. Although there is an increasing number of studies analysing the phenomenon of health tourism, little empirical data are available. This paper contributes to reducing this gap by providing reliable data on health tourism flows for the British case. Using microdata drawn from the International Passenger Survey (IPS) for the period 2000-2014, we estimate the flows, number of nights and expenditure of tourists looking for medical treatment who complete international visits of less than 12 months’ duration to and from the UK. In addition, we analyse the main destinations of UK residents (outbound health tourists), and country of origin of overseas residents (inbound health tourists). The results show the upward trend of inbound and outbound patients (163 and 364% during the period 2000-2014, respectively), the strong seasonality in outbound patients (lower during the summer), and the significant increase in the levels of expenditure of overseas residents since 2005. Poland, France, India and Hungry are the chosen countries by UK residents to be treated, whereas Irish Republic, Spain, United Arab Emirates and Greece are the main countries providing inbound health patients. Public policy considerations are given.

Fluoroquinolone efflux in Streptococcus suis is mediated by SatAB and not by SmrA

Streptococcus suis is an emerging zoonotic pathogen. With the lack of an effective vaccine, antibiotics remain the main tool to fight infections caused by this pathogen. We have previously observed a reserpine-sensitive fluoroquinolone (FQ) efflux phenotype in this species. Here, SatAB and SmrA, two pumps belonging to the ATP binding cassette (ABC) and the major facilitator superfamily (MFS), respectively, have been analyzed in the fluoroquinolone-resistant clinical isolate BB1013. Genes encoding these pumps were overexpressed either constitutively or in the presence of ciprofloxacin in this strain. These genes could not be cloned in plasmids in Escherichia coli despite strong expression repression. Finally, site-directed insertion of smrA and satAB in the amy locus of the Bacillus subtilis chromosome using ligated PCR amplicons allowed for the functional expression and study of both pumps. Results showed that SatAB is a narrow-spectrum fluoroquinolone exporter (norfloxacin and ciprofloxacin), susceptible to reserpine, whereas SmrA was not involved in fluoroquinolone resistance. Chromosomal integration in Bacillus is a novel method for studying efflux pumps from Gram-positive bacteria, which enabled us to demonstrate the possible role of SatAB, and not SmrA, in fluoroquinolone efflux in S. suis.

Oportunidades comerciales para las empresas colombianas en el mercado de EE.UU, en los estados de South Carolina, Tennessee, y Texas

El deseo de la mayoría de los empresarios es que su empresa tenga presencia en todas las partes del mundo que se pueda. Sin embargo, son pocos los que lo logran. Muchos menos los que son perdurables en el mercado internacional. Y todo esto ocurre en gran parte por el desconocimiento que tienen sobre ese entorno. Especialmente, el empresario o emprendedor colombiano, se caracteriza por no ir más allá de soñar con lograr posicionarse en el exterior, mas no trabajar para lograrlo. Este trabajo tiene como fin ayudar al empresario colombiano en ese objetivo. Pretende mostrar un contexto más profundo de, en este caso, el mercado de Estados Unidos (en los estados de Texas, South Carolina y Tennessee), para que las empresas tengan herramientas que faciliten su labor internacional. Todo esto, en el marco del Tratado de Libre Comercio entre Colombia y Estados Unidos, que entró en vigencia hace algunos años. La metodología usada para la realización de este documento, incluye una revisión bibliográfica que explica la importancia de la internacionalización empresarial; la consulta de bases de datos para elaborar un perfil exportador/importador a nivel país y a nivel estado; y la identificación de potencialidades y oportunidades que pueda tener el empresario colombiano en estos territorios específicos.
