Insight Into

Research in the service of politics? The case of Józef ObrębskiThe paper concentrates on the circumstances of the production of anthropological knowledge, created in a dynamic tension between its cognitive goal and the way it is used for political purposes. It provides an insight into a complex network of conditions (intelectual, institutional, financial, personal, political) which determined the production of knowledge in interwar Poland within the then emerging disciplines of ethnology and sociology, in the scope of what today we would call social anthropology.This case study takes a closer look at Polish anthropologist Józef Obrębski (1905-1967), a close student of Malinowski, whose outstanding achievements remained mostly unpublished and thus never came into existence in the master narrative of the history of our discipline. In the 1930s Obrębski conducted ethnosociological field research in the Polesie region in eastern Poland (nowadays, part of Belarus and Ukraine), which was part of a large scale scientific project of the Commission for Scientific Research of the Eastern Territories. This project, financed by the Polish government and headed by a politician, general Kasprzycki, was supposed to be an efficient tool in the politics of the so called state and national assimilation of the Slavic-speaking ethnic minorities. Obrębski’s political views, which were democratic and liberal in character, were opposed to the official political line whereas his functionalist anthropological stance was unacceptable for the mainstream Polish ethnology of the era, still rooted in the positivist paradigm.Anthropological knowledge produced by Obrębski, which we would call today a postcolonial and constructivist approach, began to find recognition only after his death. The biography of this scholar and the story of his “unknown” work, a great example of a non-mainstream phenomenon in a provincial country, makes it easier to reveal undisclosed mechanisms of the system and the thought-collectives of science. Nauka na usługach polityki? Przypadek Józefa ObrębskiegoArtykuł dotyczy uwarunkowań produkcji wiedzy antropologicznej w dynamicznym napięciu między jej celem poznawczym a zastosowaniem do celów politycznych. Przynosi wgląd w złożoną sieć uwarunkowań (intelektualnych, instytucjonalnych, finansowych, personalnych, politycznych) produkcji wiedzy w międzywojennej Polsce, na polu młodych dyscyplin, jakimi były wówczas etnologia i socjologia, polu, które dzisiaj nazywamy antropologią społeczno-kulturową.Bohaterem tego studium przypadku jest polski antropolog Józef Obrębski (1905-1967), bliski uczeń Malinowskiego, którego wybitne prace w większości pozostały nieopublikowane, nie funkcjonują zatem w wielkiej opowieści o historii dyscypliny. W latach 1930. Obrębski prowadził etnosocjologiczne badania terenowe na Polesiu we wschodniej Polsce (region ten dziś należy do Białorusi i Ukrainy), w ramach wdrażanego tam na szeroką skalę programu naukowego Komisji Naukowych Badań Ziem Wschodnich. Projekt ten, finansowany przez polski rząd i kierowany przez polityka, gen. Kasprzyckiego, miał być skutecznym narzędziem polityki asymilacji państwowej i narodowej słowiańskojęzycznych mniejszości etnicznych. Demokratyczne i liberalne poglądy polityczne Obrębskiego były opozycyjne wobec linii politycznej jego mocodawców, zaś stanowisko teoretyczno-metodologiczne, związane z funkcjonalizmem, było z kolei nie do przyjęcia przez polskich etnologów głównego nurtu, przywiązanych do paradygmatu pozytywistycznego.Antropologiczne osiągnięcia Obrębskiego, które dziś sytuujemy w obrębie podejścia postkolonialnego i konstruktywistycznego, zaczęły zyskiwać uznanie dopiero po jego śmierci. Biografia uczonego i dzieje jego „nieznanych” prac, ważny przykład pozamainstreamowego fenomenu w prowincjonalnym kraju, przyczyniają się do poznania nieujawnionych mechanizmów systemu i kolektywów myślowych w nauce.

RESUMO: Este trabalho tem como objetivo investigar as experiências de alunos de pós-graduação (professores em formação continuada) com atividades desenvolvidas por meio da ferramenta WebQuest, no intuito de observar indícios de autonomia por parte dos aprendizes pós-graduandos. Este estudo busca, também, observar as eventuais mudanças nas percepções dos alunos quanto ao seu papel de professor de línguas. O enfoque teórico que norteia esta pesquisa abarca as noções do construto autonomia, tanto na perspectiva do aprendiz quanto do professor (BENSON, 1997; 2008; DICKINSON, 1994; MOURA FILHO, 2009; PAIVA, 2005), bem como da WebQuest enquanto um recurso eficiente na aprendizagem (CHRISTIE, 2007; DIAS, 2010; MARCH, 2004). Esta investigação se configura como um estudo de caso. Para a geração dos dados, são utilizadas as respostas de nove participantes a questionários elaborados em um ambiente virtual criado no WIGGIO, bem como a observação da realização das atividades. Os resultados mostram que as atividades propostas por meio da ferramenta WebQuest favorecem a autonomia dos aprendizes pós-graduandos no que tange à construção de conhecimento e, por conseguinte, a mudança significativa de posturas em relação à aprendizagem. PALAVRAS-CHAVE: aprendizagem autônoma; WebQuest; ensino e aprendizagem de línguas.   ABSTRACT: This paper aims at investigating experiences from students (postgraduate teaching apprentices) with activities developed through the WebQuest tool in order to observe traces of autonomy by the postgraduate students. This research also sought to scrutinize possible changes in students' perceptions regarding their role as a language teacher. The theoretical approach that guided this investigation encompassed the notions of autonomy, both from the learner’s and the teacher´s perspectives (BENSON, 1997; 2008; DICKINSON, 1994; MOURA FILHO, 2009; PAIVA, 2005), as well as the use of WebQuest as an efficient tool for learning (CHRISTIE, 2007; DIAS, 2010; MARCH, 2004). In this case study, data were generated by the observation of the activities' accomplishment and the responses of nine of the participants to a questionnaire designed in the virtual environment. The results showed that the activities proposed through the WebQuest tool provided the postgraduate students with autonomy in the knowledge construction and, therefore, it was possible to notice significant changes in their attitudes in relation to learning. KEYWORDS: autonomous learning; WebQuest; English teaching and learning.

Environmental Crimes

Traditionally, forensic geophysics involves the study, search, localization, and mapping of buried objects or elements within soil, buildings, or water using geophysics tools for legal purposes. Recently, with the evolution of environmental crimes, forensic geophysics gave special care to detection, location, and quantification of polluting products. New techniques including the magnetic susceptibility have emerged to investigate this type of crimes. After discussing the state of the art of forensic geophysics, this chapter proposed the magnetic susceptibility as an efficient tool of environmental crimes detection. A case study of pollution detection was proposed from Tunisia. Being a fast and cheap technique, magnetic surveys represent a real promise for environmental forensic geophysics.

Time Required

Computer aided modelling, software options, as well as hardware performances have developed rapidly in the last several decades. Though the time required for building up a holistic 3D mechanical computer model for a baroque roof structure decreased significantly, it may be worth to stop at simple calculus, 2D or limited 3D modelling level, in various cases. Conclusions of the present lecture aim to identify the accuracy and reliability of the 4 levels of modelling. The recommendations formulated intend to identify the appropriate level of research according to the span, historic roof-type and state of decay of a given roof that is to be conserved. Research schemes are also suggested, aiming to offer an efficient tool for experts and engineers according to the complexity of the assessment.

Image Schema

AbstractThe framework of cognitive linguistics can be an efficient tool to represent the conceptual scope of meaning extension in reduced lexicons of pidgins and creoles. Image-schema based metaphors (Lakoff, 1993; Cienki, 1998) underlie the usage of English straight and its Tok Pisin counterpart stret, but the creole employs the concept in more contexts than English. The resultant variation in the scope of metaphor takes the form of a particular source domain being used to conceptualize more target domains than in the lexifier language. Functioning mainly as a compensation strategy, the variation is the effect of strong influence of English on the conceptual system of the creole.
