FUNDAMENTOS TEÓRICOS E METODOLÓGICOS DA PESQUISA EM EDUCAÇÃO EM CIÊNCIAS
A ideia de elaboração do livro Fundamentos Teóricos e Metodológicos da Pesquisa em Educação em Ciências, teve sua origem a partir da realização de uma disciplina de Metodologia da Pesquisa, ministrado pelos professores organizadores desta obra em 2019/01 no Programa de Pós-Graduação em Educação em Ciências (PPGEC) da Universidade Federal do Rio Grande do Sul (UFRGS). Como avaliação da referida disciplina, os alunos foram divididos em grupos e coletivamente escreveram um texto sobre cada tipo de pesquisa que costumeiramente são abordadas em Educação em Ciências. O livro está divido em seis seções, que apresentam os principais tipos de pesquisa trabalhados em Educação em Ciências: quanto a abordagem, quanto a Natureza, quanto aos objetivos, quanto aos procedimentos ou escolha do objeto de estudo, quanto a Técnica de Coleta de Dados (Instrumentos) e quanto aos Métodos de Análise de Dados. Com essa obra, esperamos contribuir com os estudos de nossos alunos (Mestrandos e Doutorandos) que vierem a cursar essa disciplina no futuro bem como proporcionar a comunidade acadêmica uma nova obra para ser utilizada nas pesquisas em Educação em Ciências.
Cancer Immunology and Immunotherapy
The interplay between tumors and their immunologic microenvironment is complex, difficult to decipher, but its understanding is of seminal importance for the development of novel prognostic markers and therapeutic strategies. The present review discusses tumor-immune interactions in several human cancers that illustrate various aspects of this complexity and proposes an integrated scheme of the impact of local immune reactions on clinical outcome. Current active immunotherapy trials have shown durable tumor regressions in a fraction of patients. However, clinical efficacy of current vaccines is limited, possibly because tumors skew the immune system by means of myeloid-derived suppressor cells, inflammatory type 2 T cells and regulatory T cells (Tregs), all of which prevent the generation of effector cells. To improve the clinical efficacy of cancer vaccines in patients with metastatic disease, we need to design novel and improved strategies that can boost adaptive immunity to cancer, help overcome Tregs and allow the breakdown of the immunosuppressive tumor microenvironment.
Amazonia: Landscape and Species Evolution
The book focuses on geological history as the critical factor in determining the present biodiversity and landscapes of Amazonia. The different driving mechanisms for landscape evolution are explored by reviewing the history of the Amazonian Craton, the associated sedimentary basins, and the role of mountain uplift and climate change. This book provdes an insight into the Meso- and Cenozoic record of Amazonia that was characterized by fluvial and long-lived lake systems and a highly diverse flora and fauna. This fauna includes giants such as the ca. 12 m long caiman Purussaurus, but also a varied fish fauna and fragile molluscs, whilst fossil pollen and spores form relics of ancestral swamps and rainforests. Finally, a review the molecular datasets of the modern Amazonian rainforest and aquatic ecosystem, discussing the possible relations between the origin of Amazonian species diversity and the palaeogeographic, palaeoclimatic and palaeoenvironmental evolution of northern South America. The multidisciplinary approach in evaluating the history of Amazonia has resulted in a comprehensive volume that provides novel insights into the evolution of this region.
Roman de Silence
This bilingual edition, based on a reexamination of the Old French manuscript, makes Silence available to specialists and students in various fields of literature, to those in women's studies and, most important, to everyone who loves a first-rate story.
Neotropical Diversification: Patterns and Processes
This book provides a comprehensive overview of the patterns of biodiversity in various neotropical ecosystems, as well as a discussion on their historical biogeographies and underlying diversification processes. All chapters were written by prominent researchers in the fields of tropical biology, molecular ecology, climatology, paleoecology, and geography, producing an outstanding collection of essays, synthetic analyses, and novel investigations that describe and improve our understanding of the biodiversity of this unique region. With chapters on the Amazon and Caribbean forests, the Atlantic rainforests, the Andes, the Cerrado savannahs, the Caatinga drylands, the Chaco, and Mesoamerica – along with broad taxonomic coverage – this book summarizes a wide range of hypotheses, views, and methods concerning the processes and mechanisms of neotropical diversification. The range of perspectives presented makes the book a truly comprehensive, state-of-the-art publication on the topic, which will fascinate both scientists and general readers alike.

Maxims and Reflections (Ricordi)
Review: "Unlike Machiavelli-inveterate dreamer and cynic-Guicciardini's mind is remarkable for the balance and masterly coolness of its judgment."-Federico Chabod "In the history of Renaissance thought, Guicciardini's Ricordi occupy a place of singular importance. Few works of the sixteenth century allow us so penetrating an insight into the views and sentiments of its author as these reflections of the great Italian historian. . . . Like Machiavelli's Prince, the Ricordi form one of the outstanding documents of a time of crisis and transition; but unlike the Prince, they range over a wide field of private as well as public life. In doing so, they revel the man as well as the political theorist."-Nicolai Rubenstein, from the Introduction.
