A historiografia sobre o período colonial na Amazônia supõe uma realidade moldada pela oposição entre um projeto colonial agrícola e a ocorrência de situações concretas de economias extrativistas, a depender da disponbilidade de capital a ser aplicado no principal meio de produção, o escravo negro. De modo que um longo período de escassez de recursos teria conformado o ciclo da economia extrativista na Região dominado pelas "drogas do sertão", substituído por esforços da gestão pombalina por um ciclo agrícola. A gestão pombalina seria a inflexão para uma dinâmica estruturada pela agricultura que, alimentada adiante por conjunturas do mercado mundial, sobretudo as ligadas à guerra da independência americana, só encontraria limitação importante na emergência do novo ciclo extrativista centrado na borracha. Os resultados aqui discutidos não demonstram ser a período pombalino o momento em que, enfim, se estabeleceram os fundamentos da economia amazônica. Trata-se, na verdade, de fundamental e criativo momento de uma trajetória que, todavia, já iniciara quase ¾ de século antes, se impôs ao protagonismo reformador que marcou o período e dele recebeu condicionantes que marcaram indelevelmente a história da Região até os dias atuais.

This paper presents a reflection on the work of the rap group from São Paulo Racionais MC's, highlighting points of dialogue between his last two studio albums: Sobrevivendo no inferno, 1997, and Nada como um dia após o outro, 2002. We found, in this discursive course, the presence of voices which intertwine and indicate a collectivized speech, seeking the identification between the slums and the group's rhetoric, but they also point out to an immersion into the subjectivity, to the problematization of the discourse itself, acting as a form of debugging of the social experience in the favela. We argue further that Sobrevivendo no inferno represents a turning point in the thinking of the quartet. Thus, themes and perspectives present, although embryonically, in the first focused album, point to dramas that take shape in the second one.

This assignment aims to do a critical and interpretative review of the masterpiece Tempo e Eternidade, published by the Brazilian poets Jorge de Lima and Murilo Mendes in 1935. It is a result of a project called Restaurando a poesia em Cristo, created by many different Brazilian poets as Tristão de Ataíde, Augusto Schimdt, and others. It is worth highlighting the importance of these poems, because of the period when they were published and for the modern proposal, as the theme, which the poets denounce the bad aspects of modernity of the century through the Holly Bible, as also for the new esthetics. In the 30s, Brazil was passing through many changes; in aspects of history - the transition between the governments of Oligarchy to the New State, in governance of Getúlio Vargas; and in the literary context, it was the beginning of the second phase of Modernism, from 1930 to 1945. This period remains the consolidation of the literary movement, in terms of esthetics, since the major proposal of Modernism is freedom of the verse and, in this second phase, the search for a renovation of the language and the enlargement of the themes in poetry, such in the religious aspect or the social-political' themes. In this perspective, it aims to show the importance of the masterpiece for the history of Brazilian literature, coated as part of a turning point between the first and second phase of Modernism, also for the thematic renovation in religious poetry and esthetics, with a new proposal of esthetics. The methodology for the analyses of the poems will be through Antonio Candido's proposal, in O estudo analítico do poema, based on interpretation and comments. Therefore it intends showing through the analyses the relevance of the masterpiece written by the Brazilian poets, to the area of religious poetry and for the literary movement of that time

Senhor Magazine’s editorial project was used as basis for several scientific studies as its content represents a turning point to national culture and it marks the decade of 1960 as one of the most significant projects of graphic design in Brazil. The present paper aims to analyze the illustration’s significance to the development of Brazilian’s editorial design and its object of study is Senhor Magazine due to the relevant connection between design and illustration. Therefore, a literature research addressing the history of editorial design in Brazil, as well as the influence of illustration in these projects was conducted. It was concluded that illustration was crucial for editorial design evolution in Brazil, and this relationship has been established since the early twentieth century. Therefore, only in the sixties it was accepted, and Senhor Magazine has become the biggest representation of this period.

X-ray laser fluorescence spectroscopy of the 2s-2p transition in Li-like ions is promising to become a widely applicable tool to provide information on the nuclear charge radii of stable and radioactive isotopes. For performing such experiments at the Experimental Storage Ring ESR, and the future NESR within the FAIR Project, a grazing incidence pumped (GRIP) x-ray laser (XRL) was set up at GSI Darmstadt using PHELIX (Petawatt High Energy Laser for heavy Ions eXperiments). The experiments demonstrated that lasing using the GRIP geometry could be achieved with relatively low pump energy, a prerequisite for higher repetition rate. In the first chapter the need of a plasma XRL is motivated and a short history of the plasma XRL is presented. The distinctive characteristic of the GRIP method is the controlled deposition of the pump laser energy into the desired plasma density region. While up to now the analysis performed were mostly concerned with the plasma density at the turning point of the main pump pulse, in this thesis it is demonstrated that also the energy deposition is significantly modified for the GRIP method, being sensitive in different ways to a large number of parameters. In the second chapter, the theoretical description of the plasma evolution, active medium and XRL emission properties are reviewed. In addition an innovative analysis of the laser absorption in plasma which includes an inverse Bremsstrahlung (IB) correction factor is presented. The third chapter gives an overview of the experimental set-up and diagnostics, providing an analytical formula for the average and instantaneous traveling wave speed generated with a tilted, on-axis spherical mirror, the only focusing system used up to now in GRIP XRL. The fourth chapter describes the experimental optimization and results. The emphasis is on the effect of the incidence angle of the main pump pulse on the absorption in plasma and on output and gain in different lasing lines. This is compared to the theoretical results for two different incidence angles. Significant corrections for the temperature evolution during the main pump pulse due to the incidence angle are demonstrated in comparison to a simple analytical model which does not take into account the pumping geometry. A much better agreement is reached by the model developed in this thesis. An interesting result is also the appearance of a central dip in the spatially resolved keV emission which was observed in the XRL experiments for the first time and correlates well with previous near field imaging and plasma density profile measurements. In the conclusion also an outlook to the generation of shorter wavelength XRL’s is given.

Phenomenology is a critical component of autobiographical memory retrieval. Some memories are vivid and rich in sensory details whereas others are faded; some memories are experienced as emotionally intense whereas others are not. Sutin and Robins (2007) identified 10 dimensions in which a memory may vary—i.e., Vividness, Coherence, Accessibility, Sensory Details, Emotional Intensity, Visual Perspective, Time Perspective, Sharing, Distancing, and Valence—and developed a comprehensive psychometrically sound measure of memory phenomenology, the Memory Experiences Questionnaire (MEQ). Phenomenology has been linked to underlining stable dispositions—i.e. personality, as well as to a variety of positive/negative psychological outcomes—well-being and life satisfaction, depression and anxiety, among others. Using the MEQ, a cross-sectional and a longitudinal study were conducted on a large sample of American and Italian adults. In both studies, participants retrieved two ‘key’ personal memories, a Turning Point and a Childhood Memory, and rated the affect and phenomenology of each memory. Participants also completed self-reported measures of personality (i.e. Neuroticism and Conscientiousness), and measures of depression, well-being and life satisfaction. The present research showed that phenomenological ratings tend (a) to cross-sectionally increase across adulthood (Study 1), and (b) to be moderately stable over time, regardless the contents of the memories (Study 2). Interrelations among memory phenomenology, personality and psychological outcome variables were also examined (Study 1 and Study 2). In particular, autobiographical memory phenomenology was proposed as a dynamic expression of personality functioning that partially explains adaptive/maladaptive psychological outcomes. In fact, the findings partially supported the hypothesized mediating effect of phenomenology on the personality association with psychological outcomes. Implications of the findings are discussed proposing future lines of research. In particular, the need for more longitudinal studies is highlighted, along with the combined application of both self-report questionnaires and narrative measures.

Degli anni Settanta si parla, ormai quasi canonicamente, come gli anni della crisi, una crisi che compare quasi simultaneamente fuori e dentro i confini nazionali, e si configura come vera e propria crisi di sistema. Considerando il turning point rappresentato dai Seventies, è diffusa l'interpretazione nel contesto italiano del paradigma politologico secondo il quale è nella mancanza e nelle assenze del sistema politico-istituzionale alle domande di modernizzazione democratica provenienti dalle soggettività che emergono in quella che è stata definita la “stagione dei movimenti” che andrebbero individuate le radici prima della scelta della violenza come strumento di lotta politica e poi del cosiddetto “riflusso”. Questo studio cerca di analizzare le dinamiche e gli sviluppi nella relazione tra movimento femminista e violenza politica in Italia tra anni settanta e anni ottanta. Per comprendere ed analizzare le dinamiche di tale sviluppo è stato necessario prima ricostruire la genealogia del concetto di violenza politica elaborato dalla filosofia politica nel XX secolo e poi confrontarlo con il concetto di violenza proposto dal pensiero femminista nello stesso arco temporale. Allo stesso tempo si è considerato il fenomeno della violenza politicamente motivata agita nel decennio settanta, analizzando le specificità del femminismo stesso, ma anche, la possibilità di individuare lo scarto – politico, ideologico e esistenziale – tra le definizioni date dalla pratica femminista alla categoria di violenza e le peculiarità degli altri movimenti che si muovevano nella scena politica e sociale tra anni settanta e anni ottanta

Romana Mazerova. The Culture of the Deaf Community in the Czech Republic Mazerova set out to discover if the deaf community in the Czech Republic can be said to have its own culture and if so what this is. She began with a comprehensive survey of the history of the deaf from 1786 to the present day, identifying a major turning point in the exclusion of sign language from the education of the deaf around 1930, a move then reinforced in the communist period to the extent that teachers of the deaf had to sign a commitment not to use sign language in their lessons. She also noted the difference between so-called signed Czech, which is an exact translation of the spoken language, and Czech sign language, which has its own structure and even dialects. Following the historical research, Mazerova studied a range of Czech and foreign materials relating to the culture of the deaf, interviewed deaf people about their experiences in school, their participation in the activities of associations for the deaf, and their experiences as a deaf person in a hearing society (these interviews are recorded on video), and visited various associations, clubs and schools for the deaf throughout the country. She concluded that while deaf people share certain behaviours which are quite distinct from those of hearing Czechs, there is little sense of a community as such. The vast majority of deaf people were not born into the deaf community and while feel that they belong together, they do not identify themselves as part of a deaf community and do not work together as a community to achieve their goals.

The ÆQUAS (a German acronym for “Work Experiences and Quality of Life in Switzerland”) study followed young workers in five occupations over their first ten years in the labor market. Participants of the study reported on working conditions and well-being at five occasions. Overall, resources at work as well as well-being, health and personal resources remained stable or increased. Concurrently, task-related stressors increased as well. This result may reflect career progress (e.g., gaining more responsibilities may be accompanied by increasing time pressure) but development in task-related stressors as well as resources may also be related to specific occupations. Several trajectories had their turning point after the first or second year of being in the labor market, which may reflect a successful professional socialization. Even though a substantial number of participants did change their occupation over these ten years (with benefits for their well-being), development over the first ten years after vocational training implies a successful transition into labor market.

The Neoproterozoic was a major turning point in Earth's surficial history, recording several widespread glaciations, the first appearance of complex metazoan life, and a major increase in atmospheric oxygen. Marine redox proxies have resulted in many different estimates of both the timing and magnitude of the increase in free oxygen, although the consensus has been that it occurred following the Marinoan glaciation, the second globally recorded “snowball Earth” event. A critically understudied rock type of the Neoproterozoic is iron formation associated with the Sturtian (first) glaciation. Samples from the <716 Ma Rapitan iron formation were analysed for their Re concentrations and Mo isotopic composition to refine the redox history of its depositional basin. Rhenium concentrations and Re/Mo ratios are consistently low throughout the bottom and middle of the iron formation, reflecting ferruginous to oxic basinal conditions, but samples from the uppermost jasper layers of the iron formation show significantly higher Re concentrations and Re/Mo ratios, indicating that iron formation deposition was terminated by a shift towards a sulfidic water column. Similarly, the δ98Mo values are close to 0.0‰ throughout most of the iron formation, but rise to ~+0.7‰ near the top of the section. The δ98Mo from samples of ferruginous to oxic basinal conditions are the product of adsorption to hematite, indicating that the Neoproterozoic open ocean may have had a δ98Mo of ~1.8‰. Together with the now well-established lack of a positive Eu anomaly in Neoproterozoic iron formations, these results suggest that the ocean was predominantly oxygenated at 700 Ma.

Our proposal presents some aspects and results of a project of the University of Bern dealing with the consequences of retirement on multilingual competences. Referring to De Bot (2007), who defined "language related major life events" as moments in life relevant for changes in multilingual competences, we assume that retirement can be a turning point in a language biography. Firstly, there are phenomena, such as the cessation of the use of a foreign language, which was formerly related to work. Secondly, retirement might elicit the improvement of foreign language skills as a way to spend excess time after retirement or as a “cognitive exercise”. Many language schools have identified the people of advanced age as a group of major interest and increasingly offer so-called 50+ (fifty plus) courses in their curriculum. Furthermore, the concept of lifelong learning is increasingly gaining importance, as the reference by the European commission (LLP) indicates. However, most of the programs are intended for educated middle-class people and there are considerably fewer offers for people who are less familiar with learning environments in general. The present paper aims at investigating the multilingual setting of an offer of the second kind: a German language course designed for retired, established Italian workforce migrants living in the city of Berne, Switzerland. The multilingual setting is given by the facts that migrants living in Berne are confronted with diglossia (Standard German and Swissgerman dialects), that the Canton of Berne is bilingual (German and French) and that the migrants' mother tongue, Italian, is one of the Swiss national languages. As previous studies have shown, most of the Italian migrants have difficulties with the acquisition of Standard German due to the diglossic situation (Werlen, 2007) or never even learnt any of the German varieties. Another outcome of the linguistic situation the migrants are confronted with in Berne, is the usage of a continuum of varieties between Swissgerman dialect and Standard German (Zanovello-Müller, 1998). Therefore, in the classroom we find several varieties of German, as well as the Italian language and its varieties. In the present paper we will investigate the use of multilingual competences within the classroom and the dynamics of second language acquisition in a setting of older adults (>60 years old), learning their host country’s language after 40 years or more of living in it. The methods applied are an ethnographic observation of the language class, combined with qualitative interviews to gain in-depth information of the subjects’ life stories and language biographies.
