Considerando a virtualiza??o da intera??o social como uma consequ?ncia da midiatiza??o, o corpo na sociedade atual encontra no avan?o tecnol?gico, que alcan?a n?veis de profundas mudan?as sociais e econ?micas, novas possibilidades de experi?ncias sexuais entre os sujeitos, motivadas, entre outras coisas, por desejos e/ou interesses financeiros. Para a realiza??o deste estudo, partimos de uma pesquisa explorat?ria interpretativa nas janelas de transmiss?es via webcam de modelos do g?nero masculino, feminino e transexual no site de relacionamento C?mera Priv?, ao longo do ano 2016 e parte de 2017, onde buscamos observar a rotina dos modelos, as estrat?gias de negocia??o destes com os clientes durante as performances sexuais no online. Estas performances se elaboram em uma composi??o de imagem e texto, integrada ao repert?rio er?tico de seus interlocutores e constru?da na rela??o individual da inter-a??o de falas, gestos e est?mulos visuais, poss?veis somente no quadro social da atualidade com a midiatiza??o. Em C?mera Priv?, percebemos como o corpo est? atrelado ao consumo a partir da virtualiza??o do desejo e das rela??es sexuais mediante transa??es comerciais entre seus usu?rios, em um mundo dominado pelo mercado de bens simb?licos. Se por um lado a sensa??o de liberdade de produ??o intelectual e audiovisual, virtualiza??o de nossas capacidades sensoriais, compartilhamento de informa??es e articula??o social no ciberespa?o na contemporaneidade t?m encorajado discursos libert?rios, a ind?stria do entretenimento, por sua vez, nos instrumentaliza em forma de rede e lan?a a sexualidade em um futuro de incertezas. / The present work seeks to investigate how the subject body is constructed as a desired and desired sexual object of consumption on the site of sexual relationships with webcam uses, called the Priv? Camera, stressing about the potentialities of the postmodern body in the context of virtualisation of the Sex between two or more people interacting in cyberspace.. Considering the virtualization of social interaction as a consequence of mediatization, the body in today's society finds in the technological advance, which reaches levels of deep social and economic changes, new possibilities of sexual experiences between the subjects, motivated among other things by desires and/or financial interests. In order to carry out this study, we started with an exploratory research on the windows of webcam transmissions of male, female and transsexual models on the C?mera Priv? relationship site, throughout 2016 and part of 2017, where we sought to observe the routine of the models, the strategies of negotiating these with clients during sexual performances in the online. These performances are elaborated in a composition of image and text, integrated to the erotic repertoire of its interlocutors and constructed in the individual relation of the inter-action of speeches, gestures and visual stimuli, possible only in the current social context with mediatization. In C?mera Priv?, we perceive how the body is linked to consumption from the virtualization of desire and sexual relations through commercial transactions among its users, in a world dominated by the market of symbolic goods. While on the one hand the sensation of freedom of intellectual and audiovisual production, virtualization of our sensorial capacities, information sharing and social articulation in contemporary cyberspace have encouraged libertarian discourses, the entertainment industry, in turn, instrumentalizes us in the form of a network And launches sexuality into a future of uncertainties.

Matematik är en av de viktigaste och mest grundläggande vetenskaperna som människan dagligen använder. Det är därför viktigt att elever får stora möjligheter att utveckla kunskaper inom ämnet i skolan. Tidigare forskning beskriver att de viktigaste kunskaperna skolan bör utveckla inom ämnet är, problemlösningsförmågor, resonemangsförmågor och förmågan att räkna på rutin. De pekar dock ut att möjligheten att utveckla problemlösningsförmågan och resonemangsförmågan sällan förekommer, därför väljer vi att göra en studie där vi analyserar matematikläromedel kopplat till dessa förmågor, för att undersöka vilka möjligheter eleverna i Sverige får för att utveckla dessa kunskaper. Syftet med studien är att belysa hur elevers möjligheter att utveckla tankeprocesser i matematik framställs i svenska matematikläromedel i grundskolans årskurs 6. Vi väljer att göra en kvantitativ innehållsanalys med hjälp av pragmatismen. Först analyserar vi tre serier av matematikläromedel och kategoriserar böckernas uppgifter i fem följande kategorier, Resonemangsuppgifter, problemlösningsuppgifter, rutinuppgifter, digitala uppgifter och övriga uppgifter. Dock är resonemangsuppgifter och problemlösningsuppgifter de vi lägger fokus på resterande uppgiftstyper är inkluderade för att kunna se en procentsats av alla olika typer av uppgifter. All data som samlas in skrivs in i ett excelark som sedan räknar ut procentsatserna för alla kategorier i varje bokserie. För att sedan validera att uppgifterna kategoriserats rätt görs ett stickprov på 20 sidor ur varje serie med hjälp av ett randomiseringsverktyg. Studiens resultat visar att elevernas möjligheter att utveckla tankeprocesser i matematik framställs i olika grad i samtliga läromedelsserier. De som alla böcker har gemensamt är att rutinuppgifter är den uppgiftstyp som förekommer mest frekvent och resonemangsuppgifter förekommer minst frekvent. Matematik gamma innehåller 79,1% rutinuppgifter, 13,7%problemlösningsuppgifter och 7,2% resonemangsuppgifter. Boken Mera Favorit matematik innehåller 68,3% rutinuppgifter, 28,8% problemlösningsuppgifter, 1,4% resonemangsuppgifter men även 1,5% övriga uppgifter. Singma matematik är den matematikbok som innehåller flest rutinuppgifter, hela 80,1%. Singma matematik är även den serien som innehåller minst andel resonemangsuppgifter med sina 0,6%. Problemlösningsuppgifter utgör 19,3% av boken Singma matematik, vilket innebär att nästan var femte uppgift är utformad som en problemlösningsuppgift.

I denna studie undersöktes hur man beskriver placering i den kausativa formen i ryska och hur språkinlärare med ryska som förstaspråk (L1) bedömer placeringsverb i svenska som andraspråk (L2). Analysen inkluderade både kvalitativa och kvantitativa metoder. Videoklipp med händelser tagna från ”Put & Take project” (Bowerman et al., 2004) användes för att samla in data om placeringshändelser på ryska. Resultatet visade att deltagarna använde placeringsverben (med olika prefix) lozhit’ lägga och stavit’ ställa men däremot inte sadit’ sätta, som också förekommer i det ryska språket, men som har en mer specifik funktion jämfört med exempelvis nederländska (Rakhilina och Lemmens, 2003:320). Ett webbaserat formulär där svenska placeringsverb presenteras tillsammans med bilder av olika föremål (Andersson & Gullberg, 2016) möjliggjorde insamling och analys av andraspråksinlärares bedömningar av svenska placeringsverb och även en jämförelse med data från svenska deltagare. Resultaten visade på stora likheter mellan den ryska gruppens bedömningar och tidigare undersökta svenska gruppers bedömningar. Detta tyder på att deltagare med ryska som L1 kan differentiera svenska placeringsverb, åtminstone när det gäller receptivt ordförråd och ej tidsbegränsade uppgifter. Skillnader kan eventuellt finnas på andra nivåer, t.ex. i produktivt ordförråd, något som behöver studeras vidare.

In my dissertation I adopt an interdisciplinary approach to explore a crucial moment in the intellectual history of Ecuador and Brazil and the way in which late 19th and early 20th century writers articulate a representational discourse that reveals the contradictions of liberalism and modernity. I argue that after entering the modern world-system, Ecuador and Brazil undergo a comparable modernization process, which entails the emergence of the cities of Guayaquil and Rio de Janeiro as new centers of political and economic power. The study of the coincidences and discrepancies between the two national processes sheds light on antagonistic cultural systems coexisting within the realms of the new metropolis. My dissertation consists of an introduction and five chapters. In the introduction, I present the theoretical framework and explain the key concepts that are common currency in contemporary attempts to articulate cultural analysis with its social and historical reality. Chapters 1 and 2 look at the origins of Ecuadorian and Brazilian identities in the works of writers José de Alencar and Juan León Mera. I intend to trace budding national identities in each of their essays about language, race, and politics, as well as in their foundational fictions, Iracema: Lenda do Ceará (1865) and Cumandá: un drama entre salvajes (1879). Chapters 3 and 4 problematize the ways in which the novels O cortiço (1890), by Brazilian Aluízo Azevedo, and A la costa (1905), by Ecuadorian Luis A. Martínez, are linked to the intricate local debates about slavery, internal migration, and the participation of both national economies in the modern world system. I contend that the narratives of Azevedo and Martínez become “hinge-novels” for glimpsing the “national” within the “liminal,” even though they fail to foresee the disencounters between the dominant and the subaltern classes. In Chapter 5, I explore the locus of enunciation from which Ecuadorian Jorge Icaza attempts to represent marginal social groups. I argue that Icaza’s Huasipungo (1934) reveals the ineffectiveness of the liberal project and helps establish the agency of marginalized groups in the Andean hacienda. The incorporation of these marginal discourses into his narratives constitutes the first endeavor to provide subaltern groups with a voice. / text

(in English): The Master thesis depicts a concept of interpersonal relationships in a novel Cecilia Valdés by the Cuban writer Cirilo Villaverde. It describes author's life and circumstances which accompanied the origin of the novel. The thesis introduces a plot of the novel, analyses the main characters and their role in the novel. It deals with a theme of the novel as a genre in general and informs about Indian and Costumbrism novel as well. It follows historic events in Cuba at the time when the novel was issued. Knowledge of the historic events is necessary for comprehension of the novel in its broader sense. The thesis examines Cecilia Valdés from the point of a concept of interpersonal relationships, deals with relationships among black people, mulattoes and white people. It analyses a relationship between the main characters which is greatly influenced by different racial origin. The topic of slavery is introduced in connection with a plot of the novel. The Master thesis compares a novel Cecila Valdés with other significant Hispano- American novels which carry similar aspects, namely with Cumandá o un drama entre salvajes by Juan León Mera and Aves sin nido by Clorinda Matto de Turner. The thesis mainly focuses on interpersonal and partner relationships in these novels which are influenced...

<p>Algorithmic trading is an automated process of order execution on electronic stock markets. It can be applied to a broad range of financial instruments, and it is&nbsp; characterized by a signicant investors&#39; control over the execution of his/her orders, with the principal goal of finding the right balance between costs and risk of not (fully) executing an order. As the measurement of execution performance gives information whether best execution is achieved, a signicant number of diffeerent benchmarks is&nbsp; used in practice. The most frequently used are price benchmarks, where some of them are determined before trading (Pre-trade benchmarks), some during the trading&nbsp; day (In-traday benchmarks), and some are determined after the trade (Post-trade benchmarks). The two most dominant are VWAP and Arrival Price, which is along with other pre-trade price benchmarks known as the Implementation Shortfall (IS).</p><p>We introduce Negative Selection as a posteriori measure of the execution algorithm performance. It is based on the concept of Optimal Placement, which represents the ideal order that could be executed in a given time win-dow, where the notion of ideal means that it is an order with the best execution price considering&nbsp; market &nbsp;conditions&nbsp; during the time window. Negative Selection is dened as a difference between vectors of optimal and executed orders, with vectors dened as a quantity of shares at specied price positionsin the order book. It is equal to zero when the order is optimally executed; negative if the order is not (completely) filled, and positive if the order is executed but at an unfavorable price.</p><p>Negative Selection is based on the idea to offer a new, alternative performance measure, which will enable us to find the&nbsp; optimal trajectories and construct optimal execution of an order.</p><p>The first chapter of the thesis includes a list of notation and an overview of denitions and theorems that will be used further in the thesis. Chapters 2 and 3 follow with a&nbsp; theoretical overview of concepts related to market microstructure, basic information regarding benchmarks, and theoretical background of algorithmic trading. Original results are presented in chapters 4 and 5. Chapter 4 includes a construction of optimal placement, definition and properties of Negative Selection. The results regarding the properties of a Negative Selection are given in [35]. Chapter 5 contains the theoretical background for stochastic optimization, a model of the optimal execution formulated as a stochastic optimization problem with regard to Negative Selection, as well as original work on nonmonotone line search method [31], while numerical results are in the last, 6th chapter.</p> / <p>Algoritamsko trgovanje je automatizovani proces izvr&scaron;avanja naloga na elektronskim berzama.

Despite the humanoid not having sensors to its navigation, it can be remotely controlled by infra-red signals. Thus, the wheeled robot can control the humanoid positioning itself behind him and, through visual information, find it and navigate it. The location of the wheeled robot is obtained merging information from odometers and from landmarks detection, using the Extended Kalman Filter. The marks are visually detected, and their features are extracted by image processing. Parameters obtained by image processing are directly used in the Extended Kalman Filter. Thus, while the wheeled robot locates and navigates the humanoid, it also simultaneously calculates its own location and maps the environment (SLAM). The navigation is done through heuristic algorithms based on errors between the actual and desired pose for each robot. The main contribution of this work was the implementation of a cooperative navigation system for two robots based on visual information, which can be extended to other robotic applications, as the ability to control robots without interfering on its hardware, or attaching communication devices / Este trabalho apresenta um sistema de navega??o cooperativa de um rob? human?ide e um rob? com rodas usando informa??o visual, com o objetivo de efetuar a navega??o do rob? human?ide n?o instrumentado utilizando-se das informa??es obtidas do rob? com rodas instrumentado. Apesar do human?ide n?o possuir sensores para sua navega??o, pode ser remotamente controlado por sinal infravermelho. Assim, o rob? com rodas pode controlar o human?ide posicionando-se atr?s dele e, atrav?s de informa??o visual, localiz?-lo e naveg?-lo. A localiza??o do rob? com rodas ? obtida fundindo-se informa??es de odometria e detec??o de marcos utilizando o filtro de Kalman estendido. Os marcos s?o detectados visualmente, e suas caracter?sticas s?o extra?das pelo o processamento da imagem. As informa??es das caracter?sticas da imagem s?o utilizadas diretamente no filtro de Kalman estendido. Assim, enquanto o rob? com rodas localiza e navega o human?ide, realiza tamb?m sua localiza??o e o mapeamento do ambiente simultaneamente (SLAM). A navega??o ? realizada atrav?s de algoritmos heur?sticos baseados nos erros de pose entre a pose dos rob?s e a pose desejada para cada rob?. A principal contribui??o desse trabalho foi a implementa??o de um sistema de navega??o cooperativa entre dois rob?s baseados em informa??o visual, que pode ser estendido para outras aplica??es rob?ticas, dado a possibilidade de se controlar rob?s sem interferir em seu hardware, ou acoplar dispositivos de comunica??o

The goal of this project was to develop novel bacterial biomarkers for use in an industrial context. These biomarkers would be used to determine aluminium industry activity impact on a local ecosystem. Sediment bacterial communities of the Saguenay River are subjected to industrial effluent produced by industry in Jonquière, QC. In-situ responses of these communities to effluent exposure were measured and evaluated as potential biomarker candidates for exposure to past and present effluent discharge. Bacterial community structure and composition between control and affected sites were investigated. Differences observed between the communities were used as indicators of a response to industrial activity through exposure to effluent by-products. Diversity indices were not significantly different between sites with increased effluent exposure. However, differences were observed with the inclusion of algae and cyanobacteria. UniFrac analyses indicated that a control (NNB) and an affected site (Site 2) were more similar to one another with regard to community structure than either was to a medially affected site (Site 5) (Figure 2.4). We did not observe a signature of the microbial community structure that could be predicted with effluent exposure. Microbial community function in relation to bacterial mercury resistance (HgR) was also evaluated as a specific response to the mercury component present in sediments. Novel PCR primers and amplification conditions were developed to amplify merP, merT and merA genes belonging to the mer-operon which confers HgR (Table 5.6). To our knowledge, the roles of merP and merT have not been explored as possible tools to confirm the presence of the operon. HgR gene abundance in sediment microbial communities was significantly correlated (p < 0.05) to total mercury levels (Figure 3.4) but gene expression was not measurable. We could not solely attribute the release of Hg0 from sediments in bioreactor experiments to a biogenic origin. However, there was a 1000 fold difference in measured Hg0 release between control and affected sites suggesting that processes of natural remediation may be taking place at contaminated sites (Figure 3.7). Abundance measurements of HgR related genes represent a strong response target to the mercury immobilized in sediments. Biomarkers built on this response can be used by industry to measure long term effects of industrially derived mercury on local ecosystems. The abundance of mer-operon genes in affected sites indicates the presence of a thriving bacterial community harbouring HgR potential. These communities have the capacity to naturally remediate the sites they occupy. This remediation could be further investigated. Additional studies will be required to develop biomarkers that are more responsive to contemporary industrial activity such as those based on the integrative oxidative stress response.
