La modernización entre cafetales : San José, Costa Rica, 1880-1930

This work examines the urban modernization of San José, Costa Rica, between 1880 and 1930, using a cultural approach to trace the emergence of the bourgeois city in a small Central American capital, within the context of order and progress. As proposed by Henri Lefebvre, Manuel Castells and Edward Soja, space is given its rightful place as protagonist. The city, subject of this study, is explored as a seat of social power and as the embodiment of a cultural transformation that took shape in that space, a transformation spearheaded by the dominant social group, the Liberal elite. An analysis of the product built environment allows us to understand why the city grew in a determined manner: how the urban space became organized and how its infrastructure and services distributed. Although the emphasis is on the Liberal heyday from 1880-1930, this study also examines the history of the city since its origins in the late colonial period through its consolidation as a capital during the independent era, in order to characterize the nineteenth century colonial city that prevailed up to 1890 s. A diverse array of primary sources including official acts, memoirs, newspaper sources, maps and plans, photographs, and travelogues are used to study the initial phase of San Jose s urban growth. The investigation places the first period of modern urban growth at the turn of the nineteenth century within the prevailing ideological and political context of Positivism and Liberalism. The ideas of the city s elite regarding progress were translated into and reflected in the physical transformation of the city and in the social construction of space. Not only the transformations but also the limits and contradictions of the process of urban change are examined. At the same time, the reorganization of the city s physical space and the beginnings of the ensanche are studied. Hygiene as an engine of urban renovation is explored by studying the period s new public infrastructure (including pipelines, sewer systems, and the use of asphalt pavement) as part of the Saneamiento of San José. The modernization of public space is analyzed through a study of the first parks, boulevards and monuments and the emergence of a new urban culture prominently displayed in these green spaces. Parks and boulevards were new public and secular places of power within the modern city, used by the elite to display and educate the urban population into the new civic and secular traditions. The study goes on to explore the idealized image of the modern city through an analysis of European and North American travelogues and photography. The new esthetic of theatrical-spectacular representation of the modern city constructed a visual guide of how to understand and come to know the city. A partial and selective image of generalized urban change presented only the bourgeois facade and excluded everything that challenged the idea of progress. The enduring patterns of spatial and symbolic exclusion built into Costa Rica s capital city at the dawn of the twentieth century shed important light on the long-term political social and cultural processes that have created the troubled urban landscapes of contemporary Latin America.

The role of comfort in child restraint use practices

Suboptimal restraint use, particularly the incorrect use of restraints, is a significant and widespread problem among child vehicle occupants, and increases the risk of injury. Previous research has identified comfort as a potential factor influencing suboptimal restraint use. Both the real comfort experienced by the child and the parent’s perception of the child’s comfort are reported to influence the optimal use of restraints. Problems with real comfort may lead the child to misuse the restraint in their attempt to achieve better comfort whilst parent-perceived discomfort has been reported as a driver for premature graduation and inappropriate restraint choice. However, this work has largely been qualitative. There has been no research that objectively studies either the association between real and parent-perceived comfort, or any association between comfort and suboptimal restraint use. One barrier to such studies is the absence of validated tools for quantifying real comfort in children. We aimed to develop methods to examine both real and parent-perceived comfort and examine their effects on suboptimal restraint use. We conducted online parent surveys (n=470) to explore what drives parental perceptions of their child’s comfort in restraint systems (study 1) and used data from field observation studies (n=497) to examine parent-perceived comfort and its relationship with observed restraint use (study 2). We developed methods to measure comfort in children in a laboratory setting (n=14) using video analysis to estimate a Discomfort Avoidance Behaviour (DAB) score, pressure mapping and adapted survey tools to differentiate between comfortable and induced discomfort conditions (study 3). The DAB rate was then used to compare an integrated booster with an add-on booster (study 4) Preliminary analysis of our recent online survey of Australian parents (study 1) indicates that 23% of parents report comfort as a consideration when making a decision to change restraints. Logistic regression modelling of data collected during the field observation study (study 2) revealed that parent-perceived discomfort was not significantly associated with premature graduation. Contrary to expectation, children of parents who reported that their child was comfortable were almost twice as likely to have been incorrectly restrained (p<0.01, 95% CI 1.24 - 2.77).In the laboratory study (study 3) we found our adapted survey tools did not provide a reliable measurement of real comfort among children. However our DAB score was able to differentiate between comfortable and induced discomfort conditions and correlated well with pressure mapping. Preliminary results from the laboratory comparison study (study 4) indicate a positive correlation between DAB rate and use errors. In experiments conducted to date, we have seen a significantly higher DAB rate in the integrated booster compared to the add-on booster (p < 0.01). However, this needs to be confirmed in a naturalistic setting and in further experiments that take length of time under observation into account. Our results suggest that while some parents report concern about their child’s comfort, parent-reported comfort levels were not associated with restraint choice. If comfort is important for optimal restraint use, it is likely to be the real comfort of the child rather than that reported by the parent. The method we have developed for studying real comfort can be used in naturalistic studies involving child occupants to further understand this relationship. This work will be of interest to vehicle and child restraint manufacturers interested in improving restraint design for young occupants as well as researchers and other stakeholders interested in reducing the incidence of restraint misuse among children.

Discovering urban citizenship in the surveillance society

Cities and urban spaces around the world are changing rapidly from their origins in the industrialising world to a post-industrial, hard wired landscape. A further embellishment is the advent of mobile media technologies supported by both existing and new communications and computing technology which claim to put the urban dweller at the heart of a new, informed and ‘liberated’ seat of participatory urban governance. This networked, sensor enabled society permits flows of information in a multitude of directions ostensibly empowering the citizenry through ‘smart’ installations such as ‘talking bus stops’ detailing services, delays, transport interconnections and even weather conditions along desired routes. However, while there is considerable potential for creative and transformative kinds of citizen participation, there is also the momentum for ‘function-creep’, whereby vast amounts of data are garnered in a broad application of urban surveillance. This kind of monitoring and capacity for surveillance connects with attempts by civic authorities to regulate, restrict, rebrand and reframe urban public spaces into governable and predictable arenas of consumption. This article considers questions around the possibilities for retaining and revitalising forms of urban citizenship, set in the context of Marshall’s original premise of civil, social and political citizenship(s) in the middle of the last century, following World War Two and the coming of the modern welfare state.

Freedom ride... I have a dream

A play in two parts on the subject of racism. Part One presents the story of the Montgomery bus boycott arising from the refusal of Rosa Parkes to give up her seat on a bus and leading to the rise of Martin Luther King, Jr. Part Two is set in contemporary Australia, in the household of a group of young people who re-create the sixties' Freedom Ride in order to heal the spirit of Auntie, an Aboriginal woman, who is the centre of their world.

Stalinismin lyhyt kurssi : Suomalaiset Moskovan Lenin-koulussa 1926-1938

This study of the Finns at the International Lenin School (ILS) reflects history of the Soviet Union during Stalin's era, history of the Communist International (Comintern) as well as history of Finnish communism. The life span of the ILS (1926-1938) matches up with creating and establishing the power structures of Stalinism. Both the ILS and Finnish Communism in the USSR became casualties of the Great Terror (1937-1938). After the WW2, however, the Soviet education was appreciated inside the Communist Party of Finland (CPF). If Finland would have become People's Democracy, the former ILS students would have composed the inner circle of the new "democratic" government. The Finnish teachers of the ILS were leaders of the CPF that was headquartered in Moscow. At the ILS studied in total 141 Finnish communists. The purpose of the ILS was to educate the communist parties' leading stratum of functionaries. They were supposed to internalize current values, methods and discipline of the Bolsheviks. This study evaluates the effects of the total school experience on the Finns that often ended in another total institution in Finland: prison. The curricula of the ILS consisted of theory of Marxism-Leninism, party history, political economics and themes of campaigns of Stalinism. The ILS year included participation in Bolshevik party life and practical work. During summer excursions (praktikas) the students could acquaint themselves with building of socialism in the Soviet Republics. At the ILS, intention to ideological moulding was not hidden. The students were supposed to adopt the Stalinist identity of the professional revolutionaries of the era. The ILS was saturated with ideology and propaganda. This study analyzes especially uses of history as vehicle of ideological standardisation and as instrument of power. Stalin contributed personally to shortcomings of history writing of the communist party. Later he supervised writing of the inclusive handbook of communism, "History of the All-Union Communist Party. Short Course". Special attention will be paid to the effects of Stalin's intervention at the ILS and inside the CPF. The life of the Finns at the ILS and outside the school is described at grass roots. The dividing line between personal and political is analyzed by charting emotional, intimate and bodily experiences of the Finns of the ILS. The fates of the ILS Finns after the studying or teaching period in Moscow are explored in detail. The protagonist among the teachers is Yrjö Sirola that was called "father of the CPF cadres". The Finnish ILS teachers and the formed students that had remained in the USSR were most severely hit by the Great Terror. The Soviet education had most importance in Finland of post WW2 period. The training at the ILS, however, did not contribute to revolution in Finland. The main heading of the study, "A Short Course of Stalinism", crystallises interpretation of the ILS as seat of learning of ideological unity of Stalinism. On the other hand, the title includes a statement of incompleteness of the Stalinist education if the schooling at the ILS had remained in one year.

Interlayer structure of iodide intercalated layered double hydroxides (LDHs)

The iodide-containing layered double hydroxides (LDHs) of Mg and Zn with AI crystallize by the inclusion of extensive positional disorder of I- ions in the interlayer region. I- ion given its poor charge to size ratio can neither screen effectively the positive charge nor participate in H-bonding with the metal hydroxide layers. Thereby the I- ions are not stabilized in sites close to the seat of positive charge of the metal hydroxide layers (6c), nor in sites that facilitate H-bonding (3b or 18h). On the other hand, OH- from water can do both and effectively displaces I- from the interlayer. (C) 2010 Elsevier Inc. All rights reserved.

Applications of Treatment Effects Models and Semiparametric Estimation

This thesis is composed of an introductory chapter and four applications each of them constituting an own chapter. The common element underlying each of the chapters is the econometric methodology. The applications rely mostly on the leading econometric techniques related to estimation of causal effects. The first chapter introduces the econometric techniques that are employed in the remaining chapters. Chapter 2 studies the effects of shocking news on student performance. It exploits the fact that the school shooting in Kauhajoki in 2008 coincided with the matriculation examination period of that fall. It shows that the performance of men declined due to the news of the school shooting. For women the similar pattern remains unobserved. Chapter 3 studies the effects of minimum wage on employment by employing the original Card and Krueger (1994; CK) and Neumark and Wascher (2000; NW) data together with the changes-in-changes (CIC) estimator. As the main result it shows that the employment effect of an increase in the minimum wage is positive for small fast-food restaurants and negative for big fast-food restaurants. Therefore, it shows that the controversial positive employment effect reported by CK is overturned for big fast-food restaurants and that the NW data are shown, in contrast to their original results, to provide support for the positive employment effect. Chapter 4 employs the state-specific U.S. data (collected by Cohen and Einav [2003; CE]) on traffic fatalities to re-evaluate the effects of seat belt laws on the traffic fatalities by using the CIC estimator. It confirms the CE results that on the average an implementation of a mandatory seat belt law results in an increase in the seat belt usage rate and a decrease in the total fatality rate. In contrast to CE, it also finds evidence on compensating-behavior theory, which is observed especially in the states by the border of the U.S. Chapter 5 studies the life cycle consumption in Finland, with the special interest laid on the baby boomers and the older households. It shows that the baby boomers smooth their consumption over the life cycle more than other generations. It also shows that the old households smoothed their life cycle consumption more as a result of the recession in the 1990s, compared to young households.

Fatores responsáveis pelo desequilíbrio na proporcionalidade na Câmara Federal

Analisa propostas apresentadas para mudanças no sistema de representatividade dos Estados e Distrito Federal na Câmara dos Deputados. O desequilíbrio está relacionado aos votos e cadeiras obtidos pelos partidos nas eleições e a distorção entre a população de determinadas unidades federativas e as cadeiras destinadas aos deputados. Esse desequilíbrio gera consequências no parlamento e contradiz o princípio de um Estado democrático de direito apresente o mesmo valor do voto para todo cidadão.

Studies on photoblastic germination in lettuce seed

It was shown, with the aid of osmotic inhibition of germination, that the action of the far-red-absorbing form of phytochrome (Pf) in promoting germination can be completed even if the seed is held under conditions where germination is not possible. An effect of the continuing action of Pf beyond the point of complete germination promotion was demonstrated by enhancement of germination rate after removal of the osmotically active solute.

Previous reports that the rate of growth in water of seeds freed from the expansion-restricting endosperm is independent of the state of phytochrome were confirmed. However, a marked, phytochrome-mediated enhancement of the growth potential of such seeds was demonstrated through restricting water uptake by incubation in an osmoticum.

An experimental system, utilizing the appearance of a geotropic curvature in the radicle of the excised axial portion of the seed, was developed for more detailed studies of the phytochrome-enhanced growth potential. It was possible to demonstrate the light effect in water as well as in osmotica; this apparently is not possible with de-endospermed entire seeds. As in intact seeds, the effect of the continuing action of Pf is to enhance the rate of the response. Secretion of a chemical inhibitor of growth by the endosperm as a possible mechanism of induction of light sensitivity has been ruled out.

The phytochrome-dependent rate of appearance of geotropic curvature in osmotica is paralleled in time by a similar dependence of the rate of early extension growth of the embryonic axis. Only the first small increment of growth is a differentially responsive to red (R) and far-red (F); the rate of later increase in length is independent of the light regime.

It was shown that the high concentrations of gibberellic acid required for germination promotion in the intact seed are due at least in part to a diffusion barrier in the endosperm, and that the occasional reports in the literature of the ineffectiveness of kinetin are probably due to the same phenomenon. It was shown that gibberellin, like red light, enhances the growth potential of the axis, but kinetin does not. The difference in rates of response obtained after R-irradiation or gibberellin treatment, together with other results reported in the literature, strongly suggests that gibberellic acid and red light promote germination by different means. The idea that kinetin promotes germination by yet another mechanism, probably operating in the cotyledons, was supported through two different experimental approaches.

The phenomenon of temperature-dependent dark germination was examined in detail, using a wide range of both temperatures and incubation times. With the aid of the half-seed system, it was demonstrated that the promotive effect of low temperature on germination could not be due to a low optimum temperature for early growth of the radicle, since the rate of that process increased with increasing temperature, up to the highest temperature used.

It was shown that phytochrome does not function at high temperatures. This fact is of considerable importance in interpreting the phenomenon of thermodormancy, since in the literature only a small part of the effect of high temperature has been ascribed to an effect on phytochrome, and at that, only to an acceleration of dark reversion of Pf to the red-absorbing form of phytochrome (Pr). Partial denaturation of phytochrome may also make some contribution.

It was shown that the germination-promoting effect of low temperature depends on the presence of Pf, and concluded that low temperatures act by delaying or preventing transformation of Pf. Support for the assumption that Pf, not Pr, is the active form of phytochrome in lettuce seeds was drawn from the same evidence.

Attempts to stimulate germination by repeated irradiation with F over relatively prolonged incubation times resulted in failure, as have similar attempts reported in the literature. However, an enhancement of growth potential in the half-seed system by the maintenance of a small amount of Pf over long periods at ordinary temperatures by repeated irradiation with F was demonstrated.

It was observed that cold storage of the dry seed prevents or delays loss of dark dormancy during post-harvest storage. No change in the response of the half-seed in osmoticum to R and F was observed in seeds that has lost dark dormancy; that is, no internal change took place to measurably increase the growth potential of the embryonic axis. This suggests that the endosperm is the seat of changes responsible for after-ripening of photoblastic lettuce seed.

Da descoberta à exclusão: uma história das diferentes máscaras da alteridade

A proposta desta tese é problematizar, isto é, produzir questões, sobre a noção de alteridade, esta tomada em seu sentido amplo do outro que não eu que nos dicionários tem como sinônimos: diferente, diverso, distinto e estranho. Mais especificamente, essa problematização se dará articulada com as transformações, também históricas, da cidade do Rio de Janeiro, escolhida por sua importância, em função de ter abrigado, desde o final do século XVIII até 1960, a sede do governo do Brasil, configurando-se como irradiadora das políticas governamentais para os outros estados e capitais. Trata-se, então, de uma pesquisa histórica que não privilegia a linearidade de acontecimentos, o que poderia nos levar a pensar que o passado nos determina de forma inexorável. Em nossa perspectiva, a história das estratégias que produziram as rotulações sobre a alteridade os outros, índios, negros escravos e mestiços postas em ação nos períodos colonial, imperial e republicano e, na contemporaneiade, pode nos levar a questionar nossa atualidade e as formas pelas quais lidamos com a alteridade, os outros, os estranhos e também com a cidade. A história que queremos contar, enfim, utiliza a própria história como modo de questionarmos nossa própria identidade e nossa contemporaneidade, de modo que nos provoque a pensar e a inventar formas singulares de lidar com os espaços urbanos e com os outros/estranhos.

Ergonomia e usabilidade na definição do conforto na classe econômica dos aviões comerciais

Os passageiros têm reclamado da diminuição do conforto na classe econômica dos aviões comerciais. A autoridade aeronáutica brasileira instituiu um selo de qualidade, mas as empresas aéreas brasileiras mantêm os mesmos arranjos internos em seus aviões. Estadissertaçãotrata da avaliação do espaço entre as poltronas e a sua influência no conforto dos passageiros em vôos comerciais. Realizaram-se avaliações da usabilidade utilizando-se um simulador de cabine para treinamento de tripulantes e um avião B737-300. Os resultados indicam uma forte relação entre os níveis de conforto e o passo (medida de repetição das fileiras de poltronas ao longo do avião).

Da espera à ousadia: o papel das ideias no pleito pelo assento permanente no Conselho de Segurança da ONU nos governos Cardoso e Lula

Esta dissertação tem como objetivo mostrar a evolução do pleito brasileiro por um assento permanente no Conselho de Segurança da Organização das Nações Unidas ao longo dos governos dos presidentes Fernando Henrique Cardoso (1995 a 2002) e Luiz Inácio Lula da Silva (2003 a 2010). Em ambos os períodos, os argumentos apresentados pela diplomacia brasileira se baseiam parcialmente em princípios que, tradicionalmente, marcam e norteiam a política externa brasileira. Este pleito foi retomado pela diplomacia brasileira no início da década de 1990. Mas as gestões realizadas em função da busca pelo assento permanente não se dão da mesma maneira nos governos dos dois presidentes nos quais esta dissertação se concentra. As mudanças que são observadas ao longo destes 16 anos estão associadas a alterações nas linhas gerais da política externa brasileira. Essas alterações permitem que se observe a uma atuação mais cautelosa no governo Cardoso e ações mais ousadas no governo Lula.

O novo lugar do Brasil no palco internacional: papeis, reconhecimento. status e identidade e o caso do G-20

Esta dissertação analisa a política externa brasileira contemporânea pelo prisma do ingresso do Brasil no G-20, a mais importante estrutura de governança global a se confrontar com a crise financeira desde 2008. É antiga a busca por reconhecimento do país, como marca da identidade internacional brasileira. A pesquisa avalia se o papel do Brasil no G-20 sinaliza o status de global player pelo entendimento teórico das escalas nas relações internacionais, em que a política externa, ao alterar sua escala, pode afetar o comportamento do agente estatal em diferentes agendas. Usando os conceitos de papel, status, identidade e reconhecimento, são analisadas as diferentes identidades internacionais do Brasil nas escalas regionais, Sul Global e internacional. O G-20 é tratado como uma instituição social, em que processos de socialização podem afetar o comportamento do Brasil entre os membros do fórum e fora dele. No G-20, o Brasil já demostrou que é susceptível aos processos de socialização por não confrontar agressivamente com as dinâmicas de poder do status quo, e por comprovar que o país valoriza seu lugar como um insider na mesa de negociações. Foi assim que o Brasil chegou a um marco nas projeções de poder e identidade no G-20. No sistema internacional, entretanto, o Brasil não alcançou o status de global player, devido aos conflituosos papéis que o país assume em sua região, no Sul Global e internacionalmente, além de suas capacidades moderadas de poder material.

A construção da ideia de constituição no Rio de Janeiro e em Buenos Aires: abordagens político-sociais de 1808 a 1824

O presente trabalho apresenta como objetivo analisar, por meio de uma visão comparativa de história, as transformações políticas ocorridas no Rio de Janeiro e em Buenos Aires, a partir de 1808, que modificaram por completo o antigo mundo ibérico, trazendo consigo o processo de emancipação política para as regiões em estudo. Por conseguinte, tais mudanças possibilitaram ainda a elaboração de projetos constitucionais para legitimar tais processos, que culminaram em 1824, com a Constituição Outorgada no Rio de Janeiro, sede do Império do Brasil, e com o Projeto Constitucional de Buenos Aires, que foi a base da constituição argentina anos depois. Na realização desse estudo, priorizaram-se como fontes os projetos constitucionais de 1813 até 1824, além de leis e decretos, que englobam o mesmo período, e de periódicos, tendo como destaque a Gazeta de Buenos Aires. No caso das fontes para o processo constitucional estabelecido no Rio de Janeiro, a ênfase foi dada aos debates da Assembleia de 1823, e seu projeto constitucional, a Constituição de 1824, além de periódicos, como Revérbero Constitucional Fluminense e o Sentinella da Liberdade na Guarita de Pernambuco. Frente às questões político-sociais procurou-se estudar a trajetória política e de vida de dois fundamentais personagens na construção da política nacional das regiões em questão. Mariano Moreno e Antonio Carlos R. Andrada Machado Silva e Araújo que se apresentaram como principais agentes para a discussão constitucional. Por fim, buscou-se compreender que as questões que permitiram a elaboração de uma monarquia constitucional e de uma república para as sociedades em tela, apesar de destoarem frente aos respectivos projetos, mantiveram o status quo em suas sociedades.

Acesso à justiça, retroalimentação e flexibilização procedimental nos juizados especiais estaduais

Este trabalho tem como objetivo principal explorar e apresentar, do ponto de vista doutrinário, legal e estatístico, três pontos centrais que carecem da atenção dos operadores do direito. O primeiro, relativo ao acesso à justiça e suas peculiaridades em apertada síntese, especialmente com olhos voltados para a retroalimentação processual, típica das sociedades de massa. Neste tópico, avaliamos dados estatísticos colhidos e fornecidos pela Comissão Especial de Juizados Especiais do Tribunal de Justiça do Estado do Rio de Janeiro. O segundo, relativo à efetividade e instrumentalidade do processo como garantias fundamentais do processo voltadas à preservação da prestação jurisdicional comprometida com a duração razoável do processo e na preservação do Estado Democrático de Direito. Por fim, o terceiro busca a análise da questão relativa aos aspectos doutrinários da flexibilização procedimental como mecanismo para a preservação da celeridade. Analisando o enfoque do Direito Inglês e Português, bem como aspectos ligados ao gerenciamento do processo e adequação, proponho a flexibilização em sede dos Juizados Especiais Cíveis como medida de concreta preservação da informalidade.
