Reason of state and a new notion of fortune : Historicising the risk society

Since the 1980s the concept of risk has produced a large and diverse volume of sociological research. Ulrich Beck’s groundbreaking risk society thesis provides a particularly engaging contribution, since it seems that nearly every sociological account of risk engages with this work. For Beck, we are living in second modernity – a new epoch that breaks with pre-modernity and industrial society due to the centrality, incalculability and reflexivity of globalised risk. While Beck’s theory is compelling, a reading of other theorists such as Foucault (2007[1978]) and Hacking (1975,1990) suggests that a difficulty with Beck’s work is that in attempting to explain what is novel about risk in contemporary times, he too quickly passes over the complexities and ruptures of historical change that impact on the history and contingency of risk. This paper begins by presenting a brief analysis of the present state of risk by introducing Beck’s historical narrative of risk from pre-modernity to the risk society; it then outlines the challenges with the “risk as epoch” argument by considering a range of literature, which suggests risk has a more complex history than proposed by Beck; and finally it highlights the value in examining strategies of statecraft in early modern Europe, specifically Machiavelli’s The Prince (2008[1513]) and Giovanni Botero’s political treatise, Della Ragion di Stato (1956[1589]) – as a means of more thoroughly understanding how our current concept of risk emerges. In doing so, this paper seeks to open up new trajectories in the historicisation of risk for other interested scholars.

Influence of environmental and instrumental variables on the non-invasive prediction of Brix in pineapple using near infrared spectroscopy

The Brix content of pineapple fruit can be non-invasively predicted from the second derivative of near infrared reflectance spectra. Correlations obtained using a NIRSystems 6500 spectrophotometer through multiple linear regression and modified partial least squares analyses using a post-dispersive configuration were comparable with that from a pre-dispersive configuration in terms of accuracy (e.g. coefficient of determination, R2, 0.73; standard error of cross validation, SECV, 1.01°Brix). The effective depth of sample assessed was slightly greater using the post-dispersive technique (about 20 mm for pineapple fruit), as expected in relation to the higher incident light intensity, relative to the pre-dispersive configuration. The effect of such environmental variables as temperature, humidity and external light, and instrumental variables such as the number of scans averaged to form a spectrum, were considered with respect to the accuracy and precision of the measurement of absorbance at 876 nm, as a key term in the calibration for Brix, and predicted Brix. The application of post-dispersive near infrared technology to in-line assessment of intact fruit in a packing shed environment is discussed.

Signifying Angels : Analyses and Interpretations of Rautavaara s Instrumental Compositions

The subject of doctoral thesis is the analysis and interpretation of instrumental pieces composed by Einojuhani Rautavaara (b. 1928) that have been given angelic titles: Archangel Michael Fighting the Antichrist from the suite Icons (1955)/Before the Icons (2006), Angels and Visitations (1978), the Double Bass Concerto Angel of Dusk (1980), Playgrounds for Angels (1981)and the Seventh Symphony Angel of Light (1994). The aim of the work is to find those musical elements common to these pieces that distinguish them from Rautavaara s other works and to determine if they could be thought of as a series. I prove that behind the common elements and titles stands the same extramusical idea the figure of an angel that the composer has described in his commentaries. The thesis is divided into three parts. Since all of the compositions possess titles that refer to the spiritual symbol of an angel, the first part offers a theoretical background to demonstrate the significant role played by angels in various religions and beliefs, and the means by which music has attempted to represent this symbol throughout history. This background traces also Rautavaara s aesthetic attitude as a spiritual composer whose output can be studied with reference to his extramusical interests including literature, psychology, painting, philosophy and myths. The second part focuses on the analysis of the instrumental compositions with angelic titles, without giving consideration to their commentaries and titles. The analyses concentrate in particular on those musical features that distinguish these pieces from Rautavaara s other compositions. In the third part these musical features are interpreted as symbols of the angel through comparison with vocal and instrumental pieces which contain references to the character of an angel, structures of mythical narration, special musical expressions, use of instruments and aspects of brightness. Finally I explore the composer s interpretative codes, drawing on Rilke s cycle of poems Ten Duino Elegies and Jung s theory of archetypes, and analyze the instrumental pieces with angelic titles in the light of the theory of musical ekphrasis.

Capillary electrochromatography: a versatile instrumental technique for nanodomain interaction studies

This doctoral thesis describes the development of a miniaturized capillary electrochromatography (CEC) technique suitable for the study of interactions between various nanodomains of biological importance. The particular focus of the study was low-density lipoprotein (LDL) particles and their interaction with components of the extracellular matrix (ECM). LDL transports cholesterol to the tissues through the blood circulation, but when the LDL level becomes too high the particles begin to permeate and accumulate in the arteries. Through binding sites on apolipoprotein B-100 (apoB-100), LDL interacts with components of the ECM, such as proteoglycans (PGs) and collagen, in what is considered the key mechanism in the retention of lipoproteins and onset of atherosclerosis. Hydrolytic enzymes and oxidizing agents in the ECM may later successively degrade the LDL surface. Metabolic diseases such as diabetes may provoke damage of the ECM structure through the non-enzymatic reaction of glucose with collagen. In this work, fused silica capillaries of 50 micrometer i.d. were successfully coated with LDL and collagen, and steroids and apoB-100 peptide fragments were introduced as model compounds for interaction studies. The LDL coating was modified with copper sulphate or hydrolytic enzymes, and the interactions of steroids with the native and oxidized lipoproteins were studied. Lipids were also removed from the LDL particle coating leaving behind an apoB-100 surface for further studies. The development of collagen and collagen decorin coatings was helpful in the elucidation of the interactions of apoB-100 peptide fragments with the primary ECM component, collagen. Furthermore, the collagen I coating provided a good platform for glycation studies and for clarification of LDL interactions with native and modified collagen. All methods developed are inexpensive, requiring just small amounts of biomaterial. Moreover, the experimental conditions in CEC are easily modified, and the analyses can be carried out in a reasonable time frame. Other techniques were employed to support and complement the CEC studies. Scanning electron microscopy and atomic force microscopy provided crucial visual information about the native and modified coatings. Asymmetrical flow field-flow fractionation enabled size measurements of the modified lipoproteins. Finally, the CEC results were exploited to develop new sensor chips for a continuous flow quartz crystal microbalance technique, which provided complementary information about LDL ECM interactions. This thesis demonstrates the potential of CEC as a valuable and flexible technique for surface interaction studies. Further, CEC can serve as a novel microreactor for the in situ modification of LDL and collagen coatings. The coatings developed in this study provide useful platforms for a diversity of future investigations on biological nanodomains.

Comprehensive Two-Dimensional Gas Chromatography: Instrumental and Methodological Development

Comprehensive two-dimensional gas chromatography (GC×GC) offers enhanced separation efficiency, reliability in qualitative and quantitative analysis, capability to detect low quantities, and information on the whole sample and its components. These features are essential in the analysis of complex samples, in which the number of compounds may be large or the analytes of interest are present at trace level. This study involved the development of instrumentation, data analysis programs and methodologies for GC×GC and their application in studies on qualitative and quantitative aspects of GC×GC analysis. Environmental samples were used as model samples. Instrumental development comprised the construction of three versions of a semi-rotating cryogenic modulator in which modulation was based on two-step cryogenic trapping with continuously flowing carbon dioxide as coolant. Two-step trapping was achieved by rotating the nozzle spraying the carbon dioxide with a motor. The fastest rotation and highest modulation frequency were achieved with a permanent magnetic motor, and modulation was most accurate when the motor was controlled with a microcontroller containing a quartz crystal. Heated wire resistors were unnecessary for the desorption step when liquid carbon dioxide was used as coolant. With use of the modulators developed in this study, the narrowest peaks were 75 ms at base. Three data analysis programs were developed allowing basic, comparison and identification operations. Basic operations enabled the visualisation of two-dimensional plots and the determination of retention times, peak heights and volumes. The overlaying feature in the comparison program allowed easy comparison of 2D plots. An automated identification procedure based on mass spectra and retention parameters allowed the qualitative analysis of data obtained by GC×GC and time-of-flight mass spectrometry. In the methodological development, sample preparation (extraction and clean-up) and GC×GC methods were developed for the analysis of atmospheric aerosol and sediment samples. Dynamic sonication assisted extraction was well suited for atmospheric aerosols collected on a filter. A clean-up procedure utilising normal phase liquid chromatography with ultra violet detection worked well in the removal of aliphatic hydrocarbons from a sediment extract. GC×GC with flame ionisation detection or quadrupole mass spectrometry provided good reliability in the qualitative analysis of target analytes. However, GC×GC with time-of-flight mass spectrometry was needed in the analysis of unknowns. The automated identification procedure that was developed was efficient in the analysis of large data files, but manual search and analyst knowledge are invaluable as well. Quantitative analysis was examined in terms of calibration procedures and the effect of matrix compounds on GC×GC separation. In addition to calibration in GC×GC with summed peak areas or peak volumes, simplified area calibration based on normal GC signal can be used to quantify compounds in samples analysed by GC×GC so long as certain qualitative and quantitative prerequisites are met. In a study of the effect of matrix compounds on GC×GC separation, it was shown that quality of the separation of PAHs is not significantly disturbed by the amount of matrix and quantitativeness suffers only slightly in the presence of matrix and when the amount of target compounds is low. The benefits of GC×GC in the analysis of complex samples easily overcome some minor drawbacks of the technique. The developed instrumentation and methodologies performed well for environmental samples, but they could also be applied for other complex samples.

Insights into Atmospheric Nucleation

Atmospheric aerosol particles have a strong impact on the global climate. A deep understanding of the physical and chemical processes affecting the atmospheric aerosol climate system is crucial in order to describe those processes properly in global climate models. Besides the climatic effects, aerosol particles can deteriorate e.g. visibility and human health. Nucleation is a fundamental step in atmospheric new particle formation. However, details of the atmospheric nucleation mechanisms have remained unresolved. The main reason for that has been the non-existence of instruments capable of measuring neutral newly formed particles in the size range below 3 nm in diameter. This thesis aims to extend the detectable particle size range towards close-to-molecular sizes (~1nm) of freshly nucleated clusters, and by direct measurement obtain the concentrations of sub-3 nm particles in atmospheric environment and in well defined laboratory conditions. In the work presented in this thesis, new methods and instruments for the sub-3 nm particle detection were developed and tested. The selected approach comprises four different condensation based techniques and one electrical detection scheme. All of them are capable to detect particles with diameters well below 3 nm, some even down to ~1 nm. The developed techniques and instruments were deployed in the field measurements as well as in laboratory nucleation experiments. Ambient air studies showed that in a boreal forest environment a persistent population of 1-2 nm particles or clusters exists. The observation was done using 4 different instruments showing a consistent capability for the direct measurement of the atmospheric nucleation. The results from the laboratory experiments showed that sulphuric acid is a key species in the atmospheric nucleation. The mismatch between the earlier laboratory data and ambient observations on the dependency of nucleation rate on sulphuric acid concentration was explained. The reason was shown to be associated in the inefficient growth of the nucleated clusters and in the insufficient detection efficiency of particle counters used in the previous experiments. Even though the exact molecular steps of nucleation still remain an open question, the instrumental techniques developed in this work as well as their application in laboratory and ambient studies opened a new view into atmospheric nucleation and prepared the way for investigating the nucleation processes with more suitable tools.

The EU and Institutional Twinning in Morocco - An inquiry into the motives of cooperation through discourse ethics

This study examines Institutional Twinning in Morocco as a case of EU cooperation through the pragmatic, ethical and moral logics of reason in Jürgen Habermas’s discourse ethics. As a former accession tool, Twinning was introduced in 2004 for legal approximation in the context of the European Neighborhood Policy. Twinning is a unique instrument in development cooperation from a legal perspective. With its long historical and cultural ties to Europe, Morocco presents an interesting case study of this new form of cooperation. We will analyse motives behind the Twinning projects on illegal immigration, environment legislation and customs reform. As Twinning is a new policy instrument within the ENP context, there is relatively little preceding research, which, in itself, constitutes a reason to inquire into the subject. While introducing useful categories, the approaches discussing “normative power Europe” do not offer methodological tools precise enough to analyse the motives of the Twinning cooperation from a broad ethical standpoint. Helene Sjursen as well as Esther Barbé and Elisabeth Johansson-Nogués have elaborated on Jürgen Habermas’ discourse ethics in determining the extent of altruism in the ENP in general. Situating the analysis in the process-oriented framework of Critical Theory, discourse ethics provides the methodological framework for our research. The case studies reveal that the context in which they operate affects the pragmatic, ethical and moral aspirations of the actors. The utilitarian notion of profit maximization is quite pronounced both in terms of the number of Twinning projects in the economic sphere and the pragmatic logics of reason instrumental to security and trade-related issues. The historical background as well internal processes, however, contribute to defining areas of mutual interest to the actors as well as the motives Morocco and the EU sometimes described as the external projection of internal values. Through its different aspects, Twinning cooperation portrays the functioning of the pragmatic, ethical and moral logics of reason in international relations.

Flood circulation in oligomictic lakes: an undervalued reason for restriction of zooplankton production [Translation from: Memorie dell'Istituto Italiano di Idrobiologia Dott.Marco de Marchi 22 9-52, 1967]

Dormancy has been observed in several species of Cyclops. Animals in dormancy are characterised by almost complete inactivity of the main appendages and sluggish intestinal peristalsis. In Cyclops vicinus dormancy can take place in copepod stages III (19%), IV (78%) and V (3%) but one and the same animal only in one developmental stage. The author gives his own results between frequency of dormancy and photoperiod (20 C, 1000 lux). He concludes that dormancy in C. vicinus can be influenced by day length and can be ended prematurely by short day length.

Corpo do lazer: reflexões a partir da vida lesada na hipermodernidade

Esta tese, Corpo do lazer: reflexões a partir da vida lesada na hipermodernidade, representa um exercício de reflexão e investigação acerca do lazer como um fenômeno psicossocial na atualidade. Enquanto reflexão, parte do corpo como centro de gravidade da subjetividade, tomando como referenciais epistemológicos alguns teóricos da primeira geração da nomeada Escola de Frankfurt, a psicanálise freudiana e estudiosos franceses que denominam a atualidade de hipermodernidade. Outros pensadores também permearam as reflexões, principalmente aqueles que viabilizam o viés crítico argumentativo. Já como investigação, um material de campo no formato de folder teve suas construções discursivas em torno do lazer destacadas, constituindo, assim, o corpus de análise da pesquisa documental de cunho qualitativo. Neste trabalho, a reflexão e a investigação se complementam na compreensão da articulação dos dois eixos principais, as esferas do desejo e do mercado, entrelaçando a noção de corpo do lazer em tempos hipermodernos e, deste modo, buscando questionar a hipermodernidade como produto e cenário em que a existência humana é prejudicada nas partículas elementares de uma vida justa, isto é, lesada nos mínimos modos de ser e estar no mundo. No âmbito do entretenimento, a vida lesada é percebida como sofrimento psicossocial e subjaz nas artimanhas sutis dos lazeres mercadológicos em expansão na hipermodernidade. Este cenário produz novos processos de subjetivação, decorrentes também das práticas de lazer atuais voltadas para consumo, e, com isso, o lazer adquire valor de troca na realidade hipermoderna. Como o corpo está no centro da cena hipermoderna em expansão nas cidades, ele é o foco dos processos de subjetivação deste estudo. Para tanto, o corpo é abordado nas noções tragicômico e erótico-narcísico, além de outros desdobramentos, no intuito de situar o corpo do lazer. A fim de explorar a temática, serão apresentadas reflexões a partir de conceitos do lazer, da inauguração do lazer na modernidade, além de análises de como ele está inserido atualmente nos mecanismos mercadológicos regidos pela lógica econômica a fomentar a indústria do entretenimento para atender os anseios humanos por prazeres como rotina dos sentidos e das sensações voltados para o corpo. Como exemplo desse cenário, elegeu-se a Barra da Tijuca, Rio de Janeiro (RJ), como espaço urbano para a realização da pesquisa, pois neste bairro a realidade hipermoderna pode ser espontaneamente verificada. Como aspectos conclusivos, o corpo do lazer demonstra ser, por um lado, o alvo dos interesses mercadológicos pautados na lucratividade e com metas a incrementar o viver no tempo supostamente livre, baseado na emotividade e estados de felicidade. Por outro lado, o corpo capturado está na condição reduzida e fragmentada pelas mesmas estratégias instrumentais do capitalismo especulativo que fomentam modos de subjetivação baseados no consumo e nos prazeres efêmeros. No entanto, esse processo ocorre com o consentimento do sujeito afetado por essas estratégias, da mesma forma como este mesmo sujeito também afeta e determina tais estratégias e, assim, produz seus efeitos nos esquemas mercadológicos. É neste interstício entre o sujeito e o mercado que percorrerão as reflexões desta tese.

Refletindo criticamente sobre as necessidades do aluno de inglês instrumental à luz da condição pós-método

O Inglês para Fins Específicos é a abordagem de ensino que ancora o trabalho feito no instituto federal no qual trabalho. Ele tem como premissa básica o ensino focado em uma análise de necessidades, ou seja, tudo o que é ensinado/aprendido está em alinhamento com o que os aprendizes necessitam em seu ambiente acadêmico e profissional. Por causa de mitos e dogmas enraizados ao longo das décadas, porém, a abordagem transformou-se exclusivamente no ensino de leitura e originou distorções na proposta original. O estudo parte da pergunta de pesquisa: O que o aluno participante desta pesquisa vê como prioridade em sua aprendizagem de inglês na escola? Outras perguntas surgiram após conversar com os dados coletados: Por que os alunos participantes querem um ensino e a escola propicia outro?; O que falta na sala de aula para amenizar essa lacuna entre o desejo dos alunos-participantes e a oferta da escola?; e, O que nós, professores, podemos fazer em relação às propostas pedagógicas para preencher esse espaço, à luz dos dados coletados e da revisão de literatura? Investigo então o posionamento de 65 aprendizes do 3 ano do ensino médio da escola na qual trabalho, através de questionários e entrevista nos moldes de um grupo focal com 5 participantes, sobre o que eles veem como prioridade na aprendizagem de inglês na escola e reflito sobre práticas pedagógicas que poderiam atender às necessidades apontadas pelos participantes. Dentro do espírito (in)disciplinar da Linguística Aplicada e dentro de um paradigma qualitativo, a análise das respostas pautou-se na recorrência de temas nas respostas às perguntas do questionário e participação no grupo focal. Temas que recorreram com frequência alta formaram categorias que serviram de base para a discussão. Selecionei duas perguntas do questionário para a análise: a pergunta (9) como você espera que seja o ensino de inglês no Ensino Médio? e a (10) quais habilidades vocês gostariam de desenvolver?, por sua relação direta com o objetivo da pesquisa. A categoria que emergiu das menções mais recorrentes nos proferimentos dos alunos foi comunicação oral, em um total de 62 menções. Outras oito categorias emergiram do corpus. Considerei frequência alta, e por isso categórica, a quantidade de 17 menções. A partir desses resultados, defendo neste trabalho que a voz do aluno (que grita urgência ao aprendizado da comunicação oral) seja ouvida nesse processo, e que uma nova pedagogia pós-metodológica seja implantada no ensino-aprendizagem de línguas no ensino médio e técnico

Esportes e lazer como instrumentos políticos da Era Vargas e governo Lula: aproximações e particularidades

Esta Tese de Doutorado foi elaborada com a pretensão de contribuir para as reflexões políticas acerca do lazer e dos esportes. A compreensão que há confusões conceituais entre eles e a convicção de que suas características favorecem o uso ideológico dessas práticas foram determinantes para o aprofundamento destes estudos. Nosso entendimento é que essas atividades se legitimam como direitos sociais e, como tal, deveriam ser contempladas no conjunto das Políticas Públicas sejam em nível federal, estadual ou municipal. Entretanto, aqui se revelam as contradições que subsidiam as análises centrais dessa Tese. É fato que o lazer e os esportes estiveram presentes nos programas das políticas sociais de diferentes governos brasileiros em distintas épocas, entretanto, o protagonismo atribuído a eles está marcado pela ideologização de suas propostas de ação. Essa hipótese pôde ser comprovada na recuperação histórica que fizemos neste trabalho. O objetivo principal da pesquisa era a análise das Políticas Públicas de Esportes e Lazer implementadas pela Era Vargas e Governo Lula para estabelecer comparações entre eles e, por esse motivo nos dedicamos a esses dois períodos históricos, emblemáticos e permeados de contradições políticas e sociais. Inquietava-nos a percepção de que, dois governos ideologicamente distintos fizessem uso dos mesmos instrumentos no diálogo com a classe trabalhadora. A contextualização dos governos dos dois líderes demarcou a analogia entre eles na utilização dos preceitos desenvolvimentistas, nacionalistas e populistas. Ainda que essas aproximações em níveis mais gerais tenham apontado coincidências relevantes, a principal constatação de nossa Tese foi a similaridade no uso ideológico do lazer e dos esportes, o que comprovou nossas intuições iniciais. Enquanto Getúlio Vargas associou as concessões de direitos trabalhistas aos programas de Recreação Operária e ao estímulo do ufanismo nacional articulado com a seleção brasileira de futebol, Lula adotou o assistencialismo explícito, incentivou a espetacularização dos esportes de rendimento e proporcionou a realização histórica dos Megaeventos Esportivos em série, no Brasil. Na Era Vargas foi possível constatar o lazer contribuindo para a domesticação dos corpos, os esportes para estabelecer uma relação harmoniosa entre dominantes e dominados e o futebol para a divulgação do regime interna e externamente. Já no Governo Lula, percebemos a retração das políticas sociais nas questões do lazer; os programas de esportes, predominantemente voltados para a descoberta de talentos e a priorização do espetáculo esportivo. A análise que fizemos não deixa dúvidas que os princípios liberais de fortalecimento do capital e aumento dos lucros, norteadores da política econômica mundial e balizadores da política macro do Governo Lula, se refletiram na definição de suas Políticas Públicas de Esportes e Lazer, que em nosso entendimento se resumiram na realização dos Megaeventos Esportivos.
