Desta forma, a pesquisa enveredou pela discuss?o do processo de expans?o urbana de Natal/RN em dire??o ? Zona Norte via pol?tica habitacional e o percurso assumido pelo com?rcio tradicional nas ruas Pomp?ia, Chegan?a e Boa Sorte. O trabalho est? embasado em pesquisa bibliogr?fica, documental e pesquisa de campo. Do ponto de vista te?rico-metodol?gico, adotou-se o m?todo regressivo-progressivo proposto por Lefebvre (2000), cuja perspectiva de investiga??o est? organizada em tr?s momentos: descritivo; anal?tico-regressivo e hist?rico-gen?rico. A an?lise desenvolvida revelou que a atividade comercial na Pomp?ia, Chegan?a e Boa Sorte apresenta um car?ter de proximidade f?sica e social, uma vez que, al?m de atender a demanda de consumo local e de bairros pr?ximos a estas, tamb?m mant?m uma clientela fidedigna no que concernem ?s rela??es de compra com o comerciante da rua. Outrossim, mesmo n?o se configurando como grandes corredores de passagem na Zona Norte, estas ruas se constituem em l?cus de representa??o s?cio-espacial embasada, por um lado na l?gica de reprodu??o hegem?nica e por um lado na reprodu??o da vida. Ainda que inserido no contexto da crise econ?mica, tamb?m vivenciada no Rio Grande do Norte e que repercute em altas taxas de desemprego, o com?rcio da Pomp?ia, Chegan?a e Boa Sorte apresenta perspectivas de crescimento, principalmente no tocante ao com?rcio informal, sendo este ?ltimo uma possibilidade de garantia de renda familiar alternativa. / Understanding the binomial commerce and city, inseparable, it is realized that the production of the urban space can be understood from the commercial activity whereas this, that is, the space, influences in the production and location of the commerce. In this way, the research began by discussing the process of urban expansion of Natal / RN towards the North Zone through housing policy and the path taken by the traditional commerce in the streets Pompeia, Chegan?a and Boa Sorte. The dissertation is based on bibliographical research, documentary and field research. From the theoretical-methodological point of view, the regressiveprogressive method proposed by Lefebvre (2000) was adopted. The research perspective of this method is organized in three moments: descriptive; analyticregressive and historical-generic. The analysis revealed that the commercial activity in Pompeia, Chegan?a and Boa Sorte has a physical and social proximity, because it meets the demand of local consumption and neighborhoods close to them and maintains a trustworthy clientele in relation to the purchase relations with The street merchant. Moreover, even though they are not configured as major passageways in the North Zone, these streets constitute a locus of socio-spatial representation based on the logic of hegemonic reproduction and reproduction of life. Although in the context of the economic crisis, also experienced in Rio Grande do Norte and which has a high unemployment rate, the commercial activity in the streets of Pompeia, Chegan?a and Boa Sorte presents growth prospects, especially with regard to informal commerce, which is a possibility to guarantee alternative family income.

To that purpose, we used a new method, the False Discovery Rate approach - FDR to empirically test those impact. To measure precisely luck and unluck, ig, the frequency of false positives (Type I errors) in the tails of the cross-section of the tdistribution associated with the alphas of funds in the sample, this new approach was applied to measure the skills of grouped shape managers of stock funds with active management in Brazil. The FDR approach offers a simple and objective method to estimate the proportion of skilled funds (with a positive alpha), alpha-zero funds, and unskilled funds (with a negative alpha) across the population. Applying the FDR technique, it was found as a result of research that the majority of funds were alpha-zero, then no truly skilled funds, and only a small proportion of truly skilled funds. / Esta pesquisa investiga, para o período entre 2002 e 2009, qual o impacto da sorte na performance dos gestores de fundos de investimentos em ações com gestão ativa no Brasil que superam o seu benchmark. Para tanto, foi usado um novo método, a abordagem False Discovery Rate - FDR para testar empiricamente esse impacto. Para mensurar precisamente sorte e azar, ou seja, a freqüência de falsos positivos (erros do tipo I) nas caudas do crosssection da distribuição t associadas aos alfas dos fundos da amostra, foi aplicada essa nova abordagem para mensurar de forma agrupada a habilidade dos gestores de fundos de ações com gestão ativa no Brasil. A abordagem FDR oferece um método simples e objetivo para estimar a proporção de fundos habilidosos (com um alfa positivo), fundos de alfa-zero, e fundos não habilidosos (com um alfa negativo) em toda a população. Aplicando-se a técnica FDR, encontrou-se como resultado da pesquisa que a maioria dos fundos foram alfa-zero, seguida pelos fundos verdadeiramente não habilidosos, e apenas uma pequena proporção de fundos verdadeiramente habilidosos.

Les voix multiples d’Amelia Rosselli (1930-1996) : figures et variations d'un sujet poétique en lutte / The multiplicitous voices of Amelia Rosselli (1930-1996) : figures and variations of the struggles of a poetic subject

Maffioli, Francesca 16 January 2017 (has links)
L'œuvre d’Amelia Rosselli entend se dessiner, au sein de la poésie lyrique italienne, comme expérience de subversion du processus de sublimation et de stylisation du corps féminin. A travers la traduction et l’analyse de poèmes choisis contenus dans les recueil Cantilena (1953), La Libellula (1958) et Variazioni belliche (1964), nous avons conduit une tentative d’exégèse critique des textes. L’analyse des poèmes se poursuit à travers une pratique dialogique avec le texte poétique, à partir d'un positionnement critique à l’intérieur du comparatisme féministe.En partant de l'idée pétrarquiste d'élimination et de suppression du corps des femmes nous avons démontré comment la tentative d’apaiser la portée potentiellement dangereuse de l’affection amoureuse a donné lieu au déni de la sensualité. Le langage de la douleur transfigurée se traduit dans une poétique du « dispositif sursensuel », un processus semblable à celui que Gilles Deleuze avait repéré dans la personnalité littéraire de Sacher-Masoch. Le processus de subversion qu’on vient d’évoquer est accompagné du bouleversement des rôles traditionnels au sein du canon poétique européen. Ces déconstructions conduiraient à un rejet du corps organique et au même temps à la révélation d’une subjectivité excentrique. La révision des modèles littéraires du canon passe également par le réécriture d'un ensemble de figures féminines du répertoire mythique et littéraire au sein de l’antiquité gréco-romaine, lesquelles, prélevées de l’imaginaire patriarcal, sont réinterprétées et à nouveau poétisées au sein d'un Sujet poétique qui cherche à faire parler la voix d’une poète femme. / Amelia Rosselli’s work took shape, within Italian lyric poetry, as an experience of subversion of the process of sublimation and of stylisation of the female body. Through the translation and the analysis of the content of poems chosen from the collections Cantilena (1953), La Libellula (1958) and Variazioni belliche (1964), I conducted a critical exegesis of the texts. I performed an analysis according to suggestions of a dialogical practice with the poetical text and with a female subjectivity often hidden, anchored to my critical investment inside feminist comparatism. From petrarchist idea of deletion and “suppression” of women’s body – deletion, of which Pasolini talked already in relation to the genesis of Italian poetry and its characterisation of the lyrical canon – I analysed how the attempt to ease the impact potentially dangerous of love affection has caused the denial of sensuality. The language of camouflaged sorrow is then established as a deliberated choice included in some poetics where it is not the statement that reveals, but the poetical word, which in its cryptic canonical measure, is able to make resonate beyond declarations. We can observe the deployment of a “sursensual device”, similar process to what Gilles Deleuze perceived in Sacher-Masoch's literary personality. The process of subversion does not seem a reconstitution of identity roles, but rather a deconstruction of the traditional model. The starting point for the analysis of those deconstructions is based on the hypothesis that the non-functionality of the desiring organisms (desiring subject and desired object) will lead to a reject of the organic and at the same time to a revelation of an eccentric subjectivity. The revision of the literary model of the canon lies in the hypothesis that a set of female figures of the mythical and literary repertoire in Greco-Roman antiquity are placed in the imaginary practice of Amelia Rosselli's poetical writing, with a view to incorporate the nature of the characters born and conceived inside and by the patriarchal imaginary and to form the body of a subject that aims at making them speak through the voice of a female poet.

<p>Mrka trulež, čiji je prouzrokovač Monilinia laxa, spada u najče&scaron;če i najznačajnije bolesti ploda ko&scaron;tičavih voćaka, naročito tre&scaron;nje. Cilj ovog rada je bio da se utvrde razlike u reakciji&nbsp; devet sorti plodova tre&scaron;nje (različitih pomolo&scaron;kih osobina) prema mrkoj truleži, uzorkovanih sa oglednog dobra Departmana za voćarstvo i vinogradarstvo, Poljoprivredni fakultet Novi Sad na Rimskim &Scaron;ančevima (koordinate: 45&deg;20&acute;N, 19&deg;51&acute;E). S obzirom da se u prirodnim uslovima plod tre&scaron;nje može zaraziti od strane vi&scaron;e patogena, biohemijski parametri su analizirani i na ve&scaron;tački inokulisanim plodovima. Ispitivane sorte su pokazale značajne razlike u pojavi oboljenja na plodu, kako u uslovima ve&scaron;tačke inokulacije, tako i u prirodnoj infekciji. U oba slučaja kod sorti su zabeležene različite ocene intenziteta zaraze, zavisno od sortimenta. Biohemijskom analizom plodova zabeležene su značajne razlike u sadržaju rastvorljivih proteina (SP), aktivnosti supereksid dismutaze (SOD), aktivnosti gvajakol peroksidaze (GPx), aktivnost pirogalol peroksidaze (PPx), lipidnoj peroksidaciji (LP). Utvrđene su značajne razlike u sadržaju &scaron;ećera, organskih kiselinih i sekundarnih metabolita (fenoli, tanini, proantocijanidini, flavonoidi, antocijanini). Takođe rezultati su pokazali razlike u antioksidantnoj aktivnost (DPPH, FRAP, ABTS i TRC testovi). Na sadržaj sekundarnih biomolekula kao i na antioksidantnu&nbsp; aktivnost&nbsp; uticali su sorta, intenzitet zaraze ploda, kao i interakcija između ova dva faktora. Većina ispitivanih sorti je pokazala visok sadržaj polifenolnih komponenti, dok je u uslovima infekcije,<br />Fitohemijska analiza i antioksidantni kapacitet plodova tre&scaron;nje inficiranih gljivom Monilinia laxa Aderh i Ruhl,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; B.

The expression information related to educational opportunities and income. For this purpose, are used four different databases associated with some empirical strategies. Thus, this study was divided into three stages: i) in the first, it appears the intergenerational transmission level of education in several economies. In addition, measures to indirect influence of environmental factors on individual effort expended. Moreover, clears up what the effect of a socio-economic growth in the test result; ii) in the second stage, we highlight the role of social and economic characteristics in educational performance. In particular, it appears the indirect influence of parental education on individual results. And finally, in the last step, it investigates the option called luck has deterministic influence on individual results. The results show different patterns of intergenerational transmission of education. In short, shall discharge to low levels of educational transmission in South American countries. On the other hand, there is a significant effect of the circumstances of the individual employee effort and a strong involvement of social and economic characteristics in educational performance. Finally, there was a substantial portion of luck option in determining the income, but also an important contribution of unobservable characteristics in individual economic results. / Este estudo propõe uma investigação sobre a clássica teoria de igualdade de oportunidades. Consideram-se informações referentes às oportunidades educacionais e de renda. Para tanto, utilizam-se quatro bases de dados distintas associadas a algumas estratégias empíricas. Diante disso, este estudo foi dividido em três etapas: i) na primeira, verifica-se o nível de transmissão intergeracional da educação em diversas economias. Adicionalmente, mensura-se a influência indireta de fatores circunstanciais sobre o esforço individual despendido. Além do mais, apura-se qual o efeito de um incremento socioeconômico no resultado do teste; ii) na segunda etapa, destaca-se o papel das características sociais e econômicas no desempenho educacional. Em especial, verifica-se a influência indireta da educação parental sobre o resultado individual. E, por fim, na última etapa, investiga-se se a denominada sorte opção tem influência determinística no resultado individual. Os resultados encontrados apontam diferentes padrões de transmissão intergeracional da educação. Em síntese, apuram-se baixos níveis de transmissão educacional nos países sul-americanos. Por outro lado, observa-se um efeito significativo das circunstâncias sobre o esforço individual empregado e uma forte participação das características sociais e econômicas no desempenho educacional. Por último, constatou-se uma parcela substancial da sorte opção na determinação da renda, como também, uma importante contribuição das características não observáveis no resultado econômico individual.

Zur Sortenbewertung von Winterroggen und Winterweizen unter Standortbedingungen im nordostdeutschen Tiefland

Macholdt, Janna Christina 14 March 2013 (has links)
Ziel dieser Arbeit war es, die Ökostabilität und Leistungsfähigkeit von verschiedenen Winterroggen- und Winterweizensorten unter differenzierten Umweltbedingungen in der Region Brandenburg zu analysieren. Im Rahmen dieser Arbeit wurden methodische Verfahren aufgezeigt und diskutiert, welche die Sortenauswahl und -empfehlung anhand eines optimierten Bewertungsschemas unterstützen können. Des Weiteren wurden spezielle Aspekte zu klimatischen Veränderungen und zur Sortenwahl auf landwirtschaftlichen Betrieben in der Region Nordostdeutschland erfasst. Auf Basis von mehrortigen und -jährigen Ergebnissen aus Sortenversuchen in Brandenburg und unter Nutzung biostatistischer Parameter wurden verschiedene Roggen- und Weizensorten analysiert. Die Bewertung zur Ertragsfähigkeit und -stabilität umfasste neben der deskriptiven Statistik und Varianzanalyse folgende Parameter: Ökovalenz, Ökoregression und Floating Checks. Zusätzlich erfolgte die Prüfung der Sortenreaktion auf verschiedene Witterungsbedingungen anhand der klimatischen Wasserbilanz. Die Ergebnisse der Sortenversuche zeigten, dass sich die Hybridsorten von Winterroggen im Vergleich der Sortentypen als deutlich ertragsfähiger und tendenziell ertragsstabiler erwiesen, vor allem auch unter trockenen Witterungsbedingungen. Beim Winterweizen erreichten die A-Sorten tendenziell stabilere Erträge, wobei die Unterschiede zwischen den Sorten innerhalb der jeweiligen Qualitätsgruppen gering ausfielen. In Ergänzung zur Auswertung der experimentellen Daten aus den Sortenversuchen wurde eine begleitende empirische Studie zur Sortenwahl in Nordostdeutschland in Form von Experteninterviews und einer Praxisumfrage bei landwirtschaftlichen Betrieben durchgeführt. Dabei wurde auch auf Zusammenhänge zwischen Sortenwahl und Witterungseffekten im Zeichen des Klimawandels eingegangen. / The object of this study was to analyse the eco-stability and capacity of different winter rye and winter wheat varieties under differentiated environmental conditions in the Brandenburg region. This paper shows and discusses a methodical procedure to support the selection and recommendation of varieties with an optimised assessment pattern. Then the paper covers special aspects on climatic changes and the selection of varieties on agricultural operations in the north-eastern region of Germany. Based on results from variety trials at multiple environments in Brandenburg and using bio statistical parameters, different varieties of rye and wheat were analysed. The evaluation of yield capacity and stability includes following parameters: eco-valence, eco-regression and floating checks. Then different impact factors on variability of yield were estimated, and the reaction of varieties to different weather conditions was analysed according to the climatic water balance. The results of the different tests showed that the yield performance is determined by different environmental factors and by variety. Of winter rye the hybrid varieties compared to other variety types were considerably more capable of yield and in tendency more stable in yield, especially also under dry weather conditions. Of winter wheat the A-varieties in tendency realized more stable yields while there was little difference between the varieties of the different quality groups. The experimental data base was supplemented by an empiric study on the selection of varieties in the German region of Brandenburg which includes interviews with experts as well as a polling of the standard practice in agricultural operations. Under the empiric study the interviewed farmers said when selecting varieties they would pay particular attention to yield safety, dryness tolerance and yield capacity.
