Essa coletânea de textos produzidos por professores e alunos da linha de pesquisa Teorias Pedagógicas, Trabalho Educativo e Sociedade, do Programa de Pós-Graduação em Educação Escolar, da Universidade Estadual Paulista (UNESP), campus de Araraquara, traz uma contribuição original a um campo no qual muito tem sido publicado nas duas últimas décadas no Brasil, o da formação de professores. A especificidade dessa coletânea reside na abordagem historicizante e crítica tanto das diretrizes oficiais para a formação de professores como das teorias pedagógicas e respectivas propostas metodológicas nesse terreno. São nove textos, que vão desde um balanço crítico do legado deixado pelo século XX no que se refere à formação de professores até questões específicas relacionadas ao trabalho do professor, passando pela questão do debate contemporâneo sobre as teorias pedagógicas.

Increased demand for energy and the search for alternative energy sources are remarkable and current facts. The management of domestic solid waste is also part of the issue in view of the possibility of power generation in existing landfills, which could provide financial autonomy to the system of waste management and improve the environmental balance of landfills in Brazil, currently only used for final solids disposal. Landfill gas is a viable alternative energy source has been tested in landfills in the World and in Brazil. Thus, the research aimed to evaluate the percentage of methane (CH4) present in three sinks of gases from a landfill in the municipality of Rio Claro – SP (Brazil), and to estimate the potential methane generation over its life through the application of a mathematical model. As a result it was found that in general the percentage of methane present in the gases is significant, between 50 and 62%. It was also noted that waste with disposal time between 8 and 12 months already are in the methanogenic stage. Finally, there was a tendency to increase the generation of methane in the transition periods of rain and drought

This paper approaches the relation between school education and psychic development in the light of cultural-historical theory and critical-historical pedagogy, discussing the triad form-content-receiver of teaching in the context of early childhood education. Considering the goal of developing the bases of theoretical thinking in children, the paper analyses role-play as leading activity in preschool and explores the contributions of child literature, highlighting the importance of providing access to artistic works which depict reality in an imaginative form as multisided and in permanent movement.

Considering that Cultural-Historical theory has been gaining importance within Brazilian Psychology in the last decades, this essay aims at contributing to understanding its ontological and epistemological foundations, introducing the concepts of singularity, particularity and universality of the dialectics that exists between them. The analysis looks to explore the implications to Psychology, both as a science and as a professional practice, of the lukacsian indication about the need to apprehend the connections between singularity, particularity and universality as a condition for understanding the essence of phenomena. In that sense, this analysis brings light to the individual/society dynamics unity affirmed by historical-dialectical materialism, which contributes to overcoming of the dichotomies usually established between the poles of this relationship.

Processes that promote cancer progression such as angiogenesis require a functional interplay between malignant and nonmalignant cells in the tumor microenvironment. The metalloprotease aminopeptidase N (APN; CD13) is often overexpressed in tumor cells and has been implicated in angiogenesis and cancer progression. Our previous studies of APN-null mice revealed impaired neoangiogenesis in model systems without cancer cells and suggested the hypothesis that APN expressed by nonmalignant cells might promote tumor growth. We tested this hypothesis by comparing the effects of APN deficiency in allografted malignant (tumor) and nonmalignant (host) cells on tumor growth and metastasis in APN-null mice. In two independent tumor graft models, APN activity in both the tumors and the host cells cooperate to promote tumor vascularization and growth. Loss of APN expression by the host and/or the malignant cells also impaired lung metastasis in experimental mouse models. Thus, cooperation in APN expression by both cancer cells and nonmalignant stromal cells within the tumor microenvironment promotes angiogenesis, tumor growth, and metastasis.

La tesi tratta dei gruppi semplici sporadici, in particolar modo dei gruppi di Mathieu. Sono state ripercorse tappe storiche fondamentali, a partire dalla semplicità del gruppo alterno An, n>4, nota a Galois, fino a giungere al teorema di classificazione dei gruppi semplici, di cui i gruppi sporadici rappresentano un caso particolare. Vengono poi proposte diverse costruzioni dei gruppi di Mathieu, passando dall'algebra alla geometria fino alla teoria dell'informazione. Quindi vengono discusse le proprietà principali dei gruppi di Mathieu, e infine si presentano congetture in cui i gruppi di Mathieu, o più in generale i gruppi sporadici, giocano un ruolo fondamentale, come ad esempio nella congettura "moonshine". Al termine della tesi vengono presentati i gruppi di Mathieu in ambiti diversi dal mondo matematico, dal gioco alla musica.

Este estudo teve por objetivo investigar quais as representações sociais que os tutores têm, sobre a própria atuação na educação a distância, em cursos de Licenciatura. Com o propósito de analisar se o tutor se reconhece como docente e participante no processo de formação do aluno o estudo de campo teve como sujeitos tutores com formação acadêmica em licenciaturas e que atuam em cursos do mesmo nível nessa modalidade, em instituição particular de Ensino Superior da Grande São Paulo. Os caminhos percorridos para tal investigação justificam-se na trajetória formativa pessoal e nos espaços da experiência que se constroem no cotidiano dessa atividade. Um estudo sobre os modelos disponíveis na modalidade a distância no ensino superior do país, um breve histórico sobre os aspectos da EAD no Brasil e uma explanação sobre o modelo no qual esses tutores atuam, além de uma aproximação com as representações sociais da profissão docente, são abordagens presentes neste trabalho, que pretendeu contribuir para a educação aprofundando conhecimentos sobre o tutor responsável pelo acompanhamento dos alunos nos ambientes virtuais de aprendizagem, considerando as possibilidades de ampliação, de alcance e democratização da educação no país. Os Resultados demonstram que há uma tendência de ser considerada, pelo tutor, uma atuação que se confunde com a essência da profissionalidade docente, numa indicação de que é necessária uma reflexão mais aprofundada sobre a função e a atuação desses profissionais.(AU)

This research studies the landscape paintings of the artist Ido Finotti, specifically the Brazilian cerrado vegetation and rivers landscape paintings, in the region of Triângulo Mineiro, mainly Uberlândia and the surrounding cities as Uberaba and Araguari. The artist produced the landscape paintings from 1947 to 1980. This study searches to understand the poetic in the paintings and identify the elements that the artist chose to create the visuality of landscape to build a regional identity. Therefore, it links the artistic and historical reflections with the general ideas about the landscape painting in the Universal History of Art and in the Brazilian History of Art through the main landscape painters. First, this work shows the trajectory of the artist Ido Finotti and the two phases of his paintings: as a decorative painter of walls from 1920 to 1940, then as an oil painter artist on canvas. Second, the national and foreign authors studied were from several fields: Visual Arts, History, History of the Art, Philosophy and Geography, but had produced literature on the idea and the subject of landscape in the painting. The initial reading was about some workmanships of Ido Finotti, which included 142 landscapes paintings; interviews; articles, periodicals and magazines collected; documents, brochures and catalogues gathered. The comparison between the written and visual sources made possible the textual construction of this research.

This thesis addresses the entanglements between the Namibian liberation struggle and the global Cold War, focusing on the socialist support provided to the South West African People Organization (SWAPO), the liberation movement that fought for the independence of the country from the South African regime. This thesis aims at analyzing three socialist models of solidarity with the SWAPO’s struggle that developed especially from the late 1970s. Combining archival sources and biographical accounts, it examines the politics of solidarity with SWAPO implemented by East Germany, Cuba, and the Italian Communist Party. The interest lies in understanding how solidarity was declined and received by internal promoters and external addressees. Thus, I explore how these three actors constructed their concept of solidarity with SWAPO according to their national and ideological contexts and how this was received by the SWAPO members who experienced it in various ways. Each socialist actor promoted solidarity with SWAPO by using varying narratives, pursuing their own objectives, and employing diverse instruments, thus carrying out different and sometimes competing visions of socialism and solidarity. On its side, SWAPO was able to take advantage from such visions, as each of them could serve its different needs in diverse ways. In providing a general overview of these three solidarity policies, this thesis has the objective of highlighting the internal pluralization of the “socialist solidarity regime” while at the same time contributing to the debate on the extent of SWAPO’s commitment to socialism during the Namibian liberation struggle. It argues that, while pragmatism has always guided SWAPO during the liberation struggle and the post-independence period, and non-alignment has always been its international stance, socialism has to some extent been a model for the revolution in Namibia, to the point that it is still influencing the SWAPO party today.

Nel seguente documento di tesi lo scopo della tecnologia blockchain è quello di creare un’architettura sicura per gli scambi di utility token basata su un sistema distribuito, ovvero un insieme eterogeneo formato da più calcolatori che appare all’utilizzatore come un unico dispositivo. Questa tesi descrive la progettazione e realizzazione di una rete blockchain Stellar permissioned capace di gestire transazioni di token applicabile a innumerevoli contesti all’interno di un ecosistema di pagamenti e di servizi. La tecnologia blockchain offre molteplici vantaggi tra cui la possibilità di diminuire le commissioni delle transazioni rispetto agli attuali sistemi di pagamento. L’architettura dell’infrastruttura di rete progettata prevede, oltre ai nodi della rete blockchain vera e propria, altri server che si occupano in particolare di offrire un servizio di database di custodia delle chiavi, un servizio di load balancing ed un servizio di accesso ai dati presenti nella rete tramite chiamate API fornite dai nodi Horizon. Oltre a questi è stato creato un elemento ad-hoc, ovvero il software BTKL, utilizzato per semplificare la comunicazione con la blockchain e per incrementare la sicurezza di comunicazione con il database di custodia.
