Question answering (QA) systems are crucial when searching for exact answers for natural language questions in the biomedical domain. Answers to many of such questions can be extracted from the 26 millions biomedical publications currently included in MEDLINE when relying on appropriate natural language processing (NLP) tools. In this work we describe our participation in the task 4b of the BioASQ challenge using two QA systems that we developed for biomedicine. Preliminary results show that our systems achieved first and second positions in the snippet retrieval sub-task and for the generation of ideal answers.

The article discusses the relationship between global history and Brazilian history and suggests an agenda for future research. It argues that global history scholars could profit from Brazil's great scholarly tradition, which conceptualises key topics of global history such as global encounters and cultural identities, power asymmetries and spatial orders. Scholars interested in Brazilian history, on the other hand, will find a set of approaches and questions from a global history perspective helpful for research on central fields of Brazil historiography such as the coffee economy, scientific racism, the Cold War and the Amazon.

No abstract

Mostra que o conceito de nação e as interpretações nacionalistas foram centrais nos discursos sobre a imigração no Brasil nos anos 1930 e 1940. Essas referências nacionais, entretanto, não são compreensíveis sem uma contextualização global. Por um lado, os atores históricos foram integrados em debates científicos que circulavam globalmente; por outro, eles tinham consciência da globalidade do assunto. Pretendo demonstrar essas hipóteses com o auxílio de dois exemplos: a sociologia migratória brasileira e os discursos de imigrantes de fala alemã no Brasil.

Recent approaches in global history and postcolonial studies have pointed to global aspects of colonialism and suggested that the history of colonialism should not be described just as a unidirectional history of power, because the reverberations of colonialism within the metropolis were also important. If we reflect further, we might ask not only if the metropolis and the colonies were entangled, but also if different colonial contexts had connections to one another. Pursuing this in the case of missionary activities, Rebekka Habermas recently demanded that scholars connect missionary history and global history so as to examine the global entanglements of the mission. She drew attention to missionary societies’ active on a global scale. It stands to reason that missionary societies, as global actors, pursued similar politics in different regions and, therefore, different regions and contexts were thereby connected. But is it possible to show direct entanglements between individual mission contexts? Can we explain certain practices and discourses in colonial situations better if we look at other regional contexts?In testing these questions, the case of the so-called “emigrant mission” (Auswanderermission), directed at Germans emigrants to Brazil by a sister organisation of the Protestant Rhenish Missionary Society, is instructive. Strangely, Habermas mentioned neither the Americas nor the emigrant mission when she proposed the analysis of global entanglements of the mission, as if there had been no missionary activities in the Americas. But it is exactly this kind of entanglement that seems most interesting, the entanglement between regions with apparently different histories. This paper tries to address this lacuna by asking if the history of the emigrant mission in Brazil can be linked with “normal” missionary contexts of, for example, missions directed at non-Europeans, in order to understand why certain discourses were circulating in Brazil. In this instance, the former German colony of Southwest Africa and the Indonesian islands of Sumatra and Nias serve as classical missionary examples, as the Rhenish Missionary Society was very active in these regions. In considering relations between German emigrants in Brazil, the German colony in Africa, and the German mission in a Dutch colony, one must remember that Brazil, although it figured very prominently in German colonial debates of the nineteenth century, was not a formal German colony.
