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.

O impacto do capital humano na criação de valor no negócio : análise nas empresas de actividades financeiras

A economia tem sofrido alterações no que concerne ao valor dos mercados/empresas, o qual começou por ser medido através de factores como a força do homem no trabalho da terra e o capital. Contudo, hoje em dia, o valor das empresas está associado a novos factores, como o conhecimento. Face às mudanças dos mercados, as empresas estão a adaptar novos modelos de gestão que consistem numa filosofia de melhoramentos contínuos através da aquisição de novos conhecimentos e envolvimento dos seus funcionários, tornando as empresas mais competitivas. O presente estudo pretende compreender como as organizações utilizam o capital intelectual, especificamente o capital humano, como ferramenta de desempenho organizacional. Do estudo conclui-se que as empresas estão cada vez mais empenhadas em transformar o conhecimento em factor competitivo, isto é, estão a adaptar-se às mudanças impostas pelos mercados. /ABSTRACT: Economy has been suffering changes concerning markets and companies value. This value started by being measured through factors like labor and capital. However, nowadays companies’ value is linked to new factors, such as knowledge. Due to changes in the markets, companies are adopting new management models, seeking for a continuous improvement philosophy through the acquisition of know-how and their employee engagement, thus becoming more competitive. This work intends to understand how organizations use the intellectual capital, specifically the human capital, as a tool of organizational performance. We may conclude that companies are more and more engaged in transforming the knowledge in a competitive advantage, that is, they are adapting themselves to the changes imposed by markets.

Delegation to workers across countries and industries : social capital and coordination needs matter

The degree of delegating authority to non-managerial and non-supervisory workers substantially varies across countries and industries. By examining worker-level data from 14 countries, I empirically explain this variation by region-specific social capital that proxies workers' degree of self-centeredness and the industry-specific need for coordination. The empirical results of this study confirm the theoretical predictions by Alonso et al. (2008) for the first time: the negative association between coordination needs and decentralization is mitigated in regions with lower self-centeredness of workers. In particular, when self-centeredness of workers (respectively, need for coordination) is very low, the degree of delegation is always high regardless of the level of the need for coordination (self-centeredness of workers). Positive associations between delegation and its benefits, including job satisfaction, wages (proxy for higher productivity), and skill upgrading of workers, are also found. These results imply that people's degree of self-centeredness affects a country's economic development patterns by changing the degree of decentralization and its benefits.

HOG CHAINS AND MARK TWAINS: A STUDY OF LABOR HISTORY, ARCHAEOLOGY, AND INDUSTRIAL ETHNOGRAPHY OF THE STEAMBOAT ERA OF THE MONONGAHELA VALLEY 1811-1950

This dissertation examines a unique working class in the United States, the men and women who worked on the steamboats from the Industrial Revolution until the demise of steam-powered boats in the mid-20th century. The steamboat was the beginning of a technological system that was developed in America and used in such great numbers that it made the rapid population of the Trans-Appalachian West possible. The steamboat was forever romanticized by images of the antebellum South or the quick wit of Samuel Clemens and his sentimental book, Life on the Mississippi. The imagination swirls with thoughts of boats, bleach white, slowly churning the calm waters of some Spanish moss covered river. The reality of the boats and the experience of those who worked on them has been lost in this nostalgic vision. This research details the history of the western steamboat in the Monongahela Valley, the birthplace of the commercial steamboat industry. The first part of this dissertation examines the literature of authors in the field of labor history and Industrial Archaeology to place this work into the larger context of published literature. The second builds a framework for understanding the various eras that the steamboat went through both in terms of technological change, but also the change the workers experienced as their identity as a working class was being shaped. The third part details the excavations of two steamboat captains houses, those of Captain James Gormley and Captain Michael A. Cox. Both men represented a time in which the steamboat was in an era of transition. Excavations at their homes yield clues to their class status and how integrated they were in the local community. The fourth part of this study documents the oral histories of steamboat workers, both men and women, and their experience on the boats and on the river. Their rapidly declining population of those who lived and worked on the boats gives urgency for their lives to be documented. Finally, this study concludes with a synthesis of how worker identity solidified in the face of technological, socio-economic, and ideological change especially during their push for unionization and the introduction of the diesel towboat.

Public service motivation in public and nonprofit service providers: The cases of Belarus and Poland

The work motivation construct is central to the theory and practice of many social science disciplines. Yet, due to the novelty of validated measures appropriate for a deep cross-national comparison, studies that contrast different administrative regimes remain scarce. This study represents an initial empirical effort to validate the Public Service Motivation (PSM) instrument proposed by Kim and colleagues (2013) in a previously unstudied context. The two former communist countries analyzed in this dissertation—Belarus and Poland—followed diametrically opposite development strategies: a fully decentralized administrative regime in Poland and a highly centralized regime in Belarus. The employees (n = 677) of public and nonprofit organizations in the border regions of Podlaskie Wojewodstwo (Poland) and Hrodna Voblasc (Belarus) are the subjects of study. ^ Confirmatory factor analysis revealed three dimensions of public service motivation in the two regions: compassion, self-sacrifice, and attraction to public service. The statistical models tested in this dissertation suggest that nonprofit sector employees exhibit higher levels of PSM than their public sector counterparts. Nonprofit sector employees also reveal a similar set of values and work attitudes across the countries. Thus, the study concludes that in terms of PSM, employees of nonprofit organizations constitute a homogenous group that exists atop the administrative regimes. ^ However, the findings propose significant differences between public sector agencies across the two countries. Contrary to expectations, data suggest that organization centralization in Poland is equal to—or for some items even higher than—that of Belarus. We can conclude that the absence of administrative decentralization of service provision in a country does not necessarily undermine decentralized practices within organizations. Further analysis reveals strong correlations between organization centralization and PSM for the Polish sample. Meanwhile, in Belarus, correlations between organization centralization items and PSM are weak and mostly insignificant. ^ The analysis indicates other factors beyond organization centralization that significantly impact PSM in both sectors. PSM of the employees in the studied region is highly correlated with their participation in religious practices, political parties, or labor unions as well as location of their organization in a capital and type of social service provided.^

Social Capital, HIV Risk Behavior and Substance Use among Recent Latino Immigrants in South Florida

Social capital, or social cohesion or group connectedness, can influence both HIV risk behavior and substance use. Because recent immigrants undergo a change in environment, one of the consequences can be a change in social capital. There may be an association among changes in social capital, and HIV risk behavior and substance use post immigration. The dissertation focused on the interface of these three variables among recent Latino immigrants (RLIs) in South Florida. The first manuscript is a systematic review of social capital and HIV risk behavior, and served as a partial background for the second and third manuscripts. Twelve papers with a measure of social capital as an independent variable and HIV risk as the dependent variable were included in the analysis. Eleven studies measured social capital at the individual level, and one study measured social capital at the group level. HIV risk was influenced by social capital, but the type of influence was dependent on the type of social capital and on the study population. Cognitive social capital, or levels of collective action, was protective against HIV in both men and women. The role of structural social capital, or levels of civic engagement/group participation, on HIV risk was dependent on the type of structural social capital and varied by gender. Microfinance programs and functional group participation were protective for women, while dysfunctional group participation and peer-level support may have increased HIV risk among men. The second manuscript was an original study assessing changes in social capital and HIV risk behavior pre to post immigration among RLIs in South Florida (n=527). HIV risk behavior was assessed through the frequency of vaginal-penile condom use, and the number of sexual partners. It was a longitudinal study using secondary data analysis to assess changes in social capital and HIV risk behavior pre immigration to two years post immigration, and to determine if there was a relationship between the two variables. There was an 8% decrease in total social capital (p ˂ .05). Reporting of ‘Never use’ of condoms in the past 90 days increased in all subcategories (p ˂ .05). Single men had a decrease in number of sexual partners (p ˂ .05). Lower social capital measured on the dimension of ‘friend and other’ was marginally associated with fewer sexual partners. The third manuscript was another original study looking at the association between social capital and substance use among RLIs in South Florida (n=527). Substance use with measured by frequency of hazardous alcoholic drinking, and illicit drug use. It was a longitudinal study of social capital and substance-use from pre to two years post immigration. Post-immigration, social capital, hazardous drinking and illicit drug use decreased (p˂.001). After adjusting for time, compared to males, females were less likely to engage in hazardous drinking (OR=.31, p˂.001), and less likely to engage in illicit drug use (OR=.67, p=.01). Documentation status was a moderator between social capital and illicit drug use. ‘Business’ and ‘Agency’ social capital were associated with changes in illicit drug use for documented immigrants. After adjusting for gender and marital status, on average, documented immigrants with a one-unit increase in ‘business’ social capital were 1.2 times more likely to engage in illicit drug use (p˂.01), and documented immigrants with one-unit increase in ‘agency’ social capital were 38% less likely to engage in illicit drug use (p˂.01). ‘Friend and other’ social capital was associated with a decrease in illicit drug use among undocumented immigrants. After adjusting for gender and marital status, on average, undocumented immigrants with a one-unit increase in ‘friend and other’ social capital were 45% less likely to engage in hazardous drinking and 44% less likely to use illicit drugs (p˂.01, p˂.05). Studying these three domains is relevant because HIV continues to be a public health issue, particularly in Miami-Dade County, which is ranked among other U.S. regions with high rates of HIV/AIDS prevalence. Substance use is associated with HIV risk behavior; in most studies, increased substance use is associated with increased chances of HIV risk behavior. Immigration, which is the hypothesized catalyst for the change in social capital, has an impact on the dynamic of a society. Greater immigration can be burdensome on the host country’s societal resources; however immigrants are also potentially a source of additional skilled labor for the workforce. Therefore, successful adaption of immigrants can have a positive influence on receiving communities. With Florida being a major receiver of immigrants to the U.S, this dissertation attempts to address an important public health issue for South Florida and the U.S. at large.

A Historical Materialist Approach to the Eurozone Crisis: Fictitious Capital, States, and Capital Accumulation

This dissertation examines the ongoing European sovereign debt crises that began with Greece in 2009, in the wake of the US subprime mortgage crisis. Through the application of a historical materialist approach, I attempt to understand the on-going crisis in the European Monetary Union (EMU) by investigating root causes of sovereign debt crises, relations of power, and main beneficiaries of the policy responses. My theoretical framework hinges on three contradictions in capitalism: the tendency towards overaccumulation, the tension between fictitious capital and the productive base, and the contradiction inherent in capitalist states between their role as a national state and as a class state. In contrast to the dominant positions that locate the cause of the crisis within either: debtor states; creditor states; or the framework at the EMU, I argue that these sovereign debt crises are actually a broader crisis of crisis of capitalism within the EMU itself. In order to do so, I trace the evolution of the political economy of the Eurozone in the post-Bretton woods era, with a particularly focus on the credit system. More specifically, I argue that these crises are the result of an interaction between three meso-level contradictions that have developed within the EMU region: 1) Germany’s postwar accumulation regime, which has produced a deep crisis of overaccumulation; 2) the contradictory processes associated with the neoliberal logic of the EMU, by which I mean the rush to lower barriers to credit and finance at the expense of all else; and 3) credit-fueled, consumption-based EMU integration in the periphery; and. These three contradictions came together in the wake of the 2007-2008 US subprime crisis to form an overall crisis of capitalism in the Eurozone, expressed, as I suggest, as a crisis of fictitious capital. This dissertation aims to contribute to the ongoing project among critical political economists to de-naturalize and re-politicize money, while challenging the hegemony of monetarism within neoliberalism. Second, there has yet to be a comprehensive study that examines the EMU, Germany, and the crises in the periphery from a holistic, historical materialist analysis.

Identificación de redes nacionales y mundiales de distribución de petróleo y gas natural y su relación con la conformación de comunidades

El presente proyecto investiga la relación entre las organizaciones con el medio y marketing, para lo cual se debe mencionar el conflicto de intereses de la comunidad y de la organización, y como se intenta percibir a la organización como un buen vecino dentro de la comunidad. A su vez éste estudio cuenta con objetivos basados en la identificación de redes de distribución de petróleo y gas natural, tanto nacionales como internacionales, para así abarcar un sector estratégico más preciso, y mostrar las relación entre las organizaciones y la conformación de comunidades. Se tienen en cuenta factores elementales en el estudio de este sector energético, como son sus principales componentes, así como un marco teórico específico que permita desarrollar el concepto de conformación de comunidades para lograr una exitosa aplicación del mismo. Del mismo modo se incluirán temas relacionados con marketing, pero desde un punto de vista más cercano a la comunidad, tomando los medios y el marketing como un concepto más importante en el impacto de las organizaciones en la comunidad, es decir tomando el concepto de marketing como aquellas comunidades que rodean las organizaciones, como éstas dos interactúan, y que impactos tienen una sobre la otra. De la misma manera se tienen resultados en cuanto a planteamientos más profundos sobre conceptos de marketing que no son desarrollados muy a menudo, los cuales conservan su esencia fundamental y siguen impactando en silencio a las organizaciones, pero que si lo estudiamos y aprovechamos de algún modo lograremos beneficios para nuestra organización y para los intereses colectivos.

Choques al hogar, trabajo Infantil y acumulación de capital humano : evidencia para Colombia

En este trabajo se estima el efecto que tienen distintos choques a los hogares sobre el logro académico de los niños. Mediante un modelo de regresión lineal, se encuentra un efecto adverso de la presencia de choques sobre el puntaje de la prueba Saber 11. Además, los resultados sugieren que el trabajo infantil es un mecanismo por el cual los choques afectan negativamente la acumulación de capital humano. Al explorar efectos heterogéneos por sexo y edad, las estimaciones indican que el efecto de los choques es guiado por los hombres y los adolescentes mayores a 14 años.

La confianza en las decisiones de presupuesto de capital: la TIR del comportamiento

En el presente artículo se desarrolla una investigación teórica que permite establecer un modelo matemático para cuantificar la influencia de la confianza de los gerentes en el proceso de presupuesto de capital, en particular sobre la Tasa Interna de Retorno. El Modelo permite concluir que el exceso de confianza es un factor que tiende a elevar esta tasa que esperan recibir los inversionistas tras invertir en determinados proyectos, generando así, en ciertas ocasiones, una toma de decisiones al interior de las empresas basada en cifras sesgadas, comprometiendo así los recursos de la misma.

A industrialização como criadora de conjuntos habitacionais para o operariado: o caso do Bairro da Empresa de Cimentos de Leiria: Maceira-Liz

A Revolução Industrial consistiu num amplo conjunto de mudanças que ocorreu nos séculos XVIII e XIX na Europa, em que a grande metamorfose na sociedade sucedeu devido à substituição do trabalho manual pelo uso da máquina. Constituiu-se como fenómeno abrangente que congregou fatores demográficos, sociais, ideológicos, políticos e económicos. A busca de melhores condições de vida e de trabalho, foi fator decisivo para o aumento de população nos grandes núcleos urbanos, circunstância que determinou a procura de uma solução que resolvesse a questão do alojamento da classe trabalhadora. Surgiram assim teorias utópicas e sociais e também modelos urbanísticos dos quais se salientam: o Falanstério de Charles Fourier, Familistério de Jean-Baptiste Godin entre outros. Em Portugal, a industrialização ocorreu mais tarde que na restante Europa, assim como as evoluções e transformações associadas a esta. É neste contexto, que a partir do século XIX, o sector agrícola no país foi sendo gradualmente substituído pela indústria. O aumento da industrialização conduziu a um incremento da concentração de mão-de-obra próxima de grandes cidades industriais, ocorrência que fomentou o aparecimento dos primeiros núcleos habitacionais destinados à classe operária. A cidade sofreu, assim, alterações assinaladas por uma série de acontecimentos resultantes da Revolução Industrial, a par da falta de estratégias ligadas à questão da habitação para as classes desfavorecidas. É neste enquadramento que surge o Bairro do Pessoal da Empresa de Cimento de Leiria, Maceira-Liz. Este procurou responder às necessidades dos trabalhadores oferecendo-lhes boa qualidade de vida. Foi dotado de infraestruturas e equipamentos como a “Casa do Pessoal” ou a Cooperativa Abastecedora, entre outros, necessários ao bom funcionamento e permitindo uma maior sociabilidade entres os seus habitantes Desta forma, para demostrar a sua importância, introduz-se o Bairro do Pessoal da E.C.L no estudo do contexto internacional e nacional. Observam-se e criam-se relações com os modelos das cidades utópicas do século XIX e os conjuntos industriais em Portugal, detentores de alojamento destinado à classe trabalhadora, fazendo uma análise urbanística detalhada do Bairro do Pessoal de Maceira- Liz, uma “Utopia” construída segundo o espirito progressista do seu fundador Henrique Sommer.A partir do estudo dos fundamentos teórico-práticos, da forma de implantação e construção, bem como dos vários planos elaborados para este complexo - que demonstravam uma tentativa de inovar, através da construção de respostas às mudanças da sociedade e arquitetura em Portugal- poderá observar- -se que Maceira-Liz tinha alternativas para resolver a situação sócio- laboral dos operários e tentava resolver questões como a insalubridade da habitação operária da I República. O Bairro do Pessoal de E.C.L. ou Bairro de Maceira-Liz é um dos mais significativos exemplos de urbanismo do tipo fabril em Portugal, que permite fazer uma reflexão crítica e arquitetónica do papel que a arquitetura assume face à questão das diferenças sociais de classes, ao mesmo tempo que se propõe uma solução de revitalização do Bairro a fim de contribuir para a sua preservação e conservação da sua identidade; ABSTRACT: The Industrial Revolution consisted in a wide range of changes that occurred in the eighteenth and nineteenth centuries in Europe, where the great metamorphosis in society succeeded due to the replacement of manual work by the use of machinery. It was established as a wide-ranging phenomenon which gathered demographic, social, ideological, political and economic factors. The search of better conditions of life and work was a decisive factor for the increase of population in major urban centers, a circumstance that led to the search for a solution to solve the question of working-class housing. Thus, utopian and social theories emerged, as also as urban models, of which we stand out: the Charles Fourier Phalanstery, Jean- Baptiste Godin Familistère and others. In Portugal, the industrialization occurred later than in the rest of Europe, as well as developments and changes associated with this. It is in this context that, starting in the nineteenth century, the agricultural sector in the country had been gradually replaced by the industry. The increased industrialization has led to an enlarged concentration of labor work close to major industrial cities, occurrence that fomented the appearance of the first housing units for the working class. So, the city suffered changes shown by a series of events resulting from the Industrial Revolution, together with the lack of strategies linked to the issue of housing for disadvantaged classes. It is in this context that comes the Neighborhood “Bairro do Pessoal da Empresa de Cimento de Leirio, Maceira – Liz”. This tried to respond to workers’ needs by offering them good quality of life. It was gifted with infrastructure and equipment as the “Staff Home” or the Cooperative Supplying, among others, needed for a proper functioning and allowing a greater sociability among its inhabitants. So, to demonstrate its importance, the Quarter of the Cement Company is introduced in the study of national and international context. Relationships with models of utopian cities in the nineteenth and the industrial plants in Portugal, owners of housing for the working class, are observed and created, making a detailed and urban analysis of the Quarter of the Cement Company, a “utopia “ built according to the progressive spirit of its founder Henry Sommer . From the study of the theoretical and practical fundamentals, the way of implementation and construction, as well as the various plans drawn up for this complex - which showed a determination to innovate by building responses to changes in society and architecture in Portugal - it can be founded that Maceira -Liz had alternatives to solve the socio- labor situation of the workers and tried to solve issues such as the unhealthiness of the working room of the First Republic. The Quarter of the Cement Company is one of the most significant examples of the industrial type urbanism in Portugal, which allows a critical and architectural reflection of the role that architecture assumes in what concerns the social class differences issues, while it is proposed a revitalization solution for the Neighborhood in order to contribute to the preservation and conservation of its identity
