Literary texts and intercultural learning: exploring new directions

Hoje em dia, a interculturalidade faz parte das análises, estudos e pensamentos de muitos estudiosos e teóricos das mais diversas disciplinas.

Texts prepared for delivery at Paul Krugman's honorary doctorate by three Lisbon universities on 27 February, 2012

Three texts were prepared for delivery at the first honorary doctorate awarded simultaneously by three Lisbon universities on 27 February, 2012: an introduction, a lecture and a comment. The event included the award of member of the Lisbon Academy of Science (ACL) by Manuel Jacinto Nunes, dean of the economics and finance section of ACL who proposed his name and Olivier Blanchard’s on the 30th anniversary of James Tobin receiving an honorary doctorate from Nova University. On 24 February , Paul Krugman visited ACL and participated in a session of the project dubbed “Letter to the lusofonia Queen”. Since this project is promoted by Nova SBE’s Center for Globalization and Governance and has been featured in some of the graduate courses, a short note on the meeting is included in annex. On 15 June, the three universities authorized an edition in Portuguese and donated the copyrights to a student award on “Krugman economics”, in a way still to be determined by the editor. The lecture and the comment will be translated as soon as a suitable publisher is found. Since a lot of the teaching at Nova SBE is in English, it seemed appropriate to reproduce the original texts in the order in which they were presented. A lively question and answer period was also recorded by Nova TV and should be made available in the book, together with highlights of the media coverage. Introduced as a “militant economist”, he speaks about a crisis “his mind loves but does not let the heart forget the poor and the unemployed”. The Nobel prize winner described as a“progressist pessimist of the world economy” concludes with a severe indictment of the profession. “In normal times, when things are going pretty well, the world can function reasonably well without professional economic advice. It’s in times of crisis, when practical experience suddenly proves useless and events are beyond anyone’s normal experience, that we need professors with their models to light the path forward. And when the moment came, we failed”. The comment, by the official responsible for Paul Krugman’s mission to Portugal in 1976, contains an equally dire prediction: “I would very much like to see in the near future the weakening of the influence not only of freshwater economists but also of their conservative European followers. But I fear that this will not happen until we find ourselves in a more calamitous situation than at present”. Fortunately Silva Lopes closes in the hope “that the ideas of Paul Krugman will soon have more influence in policy makers than at present seems to be the case”.

Risky behavior regarding drug use and HIV infection: an Internet questionnaire coupled with short education texts for Portuguese speakers

Surveys of risky behavior relating to HIV/AIDS are generally made for groups at risk of infection, for which HIV/AIDS prevalence is usually expected to be higher than in the general population. Therefore, an educational homepage in Portuguese was created on the Internet to inform/ask internauts regarding knowledge and behavior. The internauts were classified as adolescents (13 to 25 years) and adults (>25 years). The number of STDs was reported as 1. 8 ± 2. 6 infections (range: 1 to 20 infections); 43% used condoms during sexual intercourse. Alcohol consumption was reported by 63% and illicit drug use by 32% (marijuana 24% and inhalants 15%). Among the adolescents, 31% did not classified alcohol as a drug. The adults more frequently reported homosexuality, anal intercourse and STDs, although the adolescents also presented high rates of risky behavior. These results show the need to reach out to internauts through better control strategies. Different types of strategies must be encouraged, in order to reach people that use this means of communication and entertainment.

Automatic extraction of concepts from texts and applications

The extraction of relevant terms from texts is an extensively researched task in Text- Mining. Relevant terms have been applied in areas such as Information Retrieval or document clustering and classification. However, relevance has a rather fuzzy nature since the classification of some terms as relevant or not relevant is not consensual. For instance, while words such as "president" and "republic" are generally considered relevant by human evaluators, and words like "the" and "or" are not, terms such as "read" and "finish" gather no consensus about their semantic and informativeness. Concepts, on the other hand, have a less fuzzy nature. Therefore, instead of deciding on the relevance of a term during the extraction phase, as most extractors do, I propose to first extract, from texts, what I have called generic concepts (all concepts) and postpone the decision about relevance for downstream applications, accordingly to their needs. For instance, a keyword extractor may assume that the most relevant keywords are the most frequent concepts on the documents. Moreover, most statistical extractors are incapable of extracting single-word and multi-word expressions using the same methodology. These factors led to the development of the ConceptExtractor, a statistical and language-independent methodology which is explained in Part I of this thesis. In Part II, I will show that the automatic extraction of concepts has great applicability. For instance, for the extraction of keywords from documents, using the Tf-Idf metric only on concepts yields better results than using Tf-Idf without concepts, specially for multi-words. In addition, since concepts can be semantically related to other concepts, this allows us to build implicit document descriptors. These applications led to published work. Finally, I will present some work that, although not published yet, is briefly discussed in this document.

Exploring Literary Landscapes: From Texts to Spatiotemporal Analysis through Collaborative Work and GIS

This article argues that the study of literary representations of landscapes can be aided and enriched by the application of digital geographic technologies. As an example, the article focuses on the methods and preliminary findings of LITESCAPE.PT—Atlas of Literary Landscapes of Mainland Portugal, an on-going project that aims to study literary representations of mainland Portugal and to explore their connections with social and environmental realities both in the past and in the present. LITESCAPE.PT integrates traditional reading practices and ‘distant reading’ approaches, along with collaborative work, relational databases, and geographic information systems (GIS) in order to classify and analyse excerpts from 350 works of Portuguese literature according to a set of ecological, socioeconomic, temporal and cultural themes. As we argue herein this combination of qualitative and quantitative methods—itself a response to the difficulty of obtaining external funding—can lead to (a) increased productivity, (b) the pursuit of new research goals, and (c) the creation of new knowledge about natural and cultural history. As proof of concept, the article presents two initial outcomes of the LITESCAPE.PT project: a case study documenting the evolving literary geography of Lisbon and a case study exploring the representation of wolves in Portuguese literature.

Narrativity in Biblical and Related Texts - La narrativité dans la Bible et les textes apparentés

Seventeen innovative studies are collected in this volume which has been produced under the aegis of the Centre for Biblical Studies, University of Manchester, and L'Institut des sciences bibliques, Université de Lausanne. The majority of the studies engage with narrative through providing insightful working examples. Building on the many contributions of recent narratological research, for the most part the studies in this collection avoid the technical language of narratology as they present fresh insights at many levels. Some essays focus more on the implied author, some on the implied reader or hearer, and some on the way particular messages are constructed; some of the studies consider how author, message and reader are all interconnected. There are several creative proposals for refining genre definition, from law and wisdom to gospel and apocryphal writings. Some studies highlight the way in which narratives can contain ethical, religious, and cultural messages. Sensitivity to narrative is also shown by some contributors to expose in intruing ways the redactional processes behind the final form of texts. Students of narrative in the ancient world will find much to consider in this book, and others engaged with literary studies more generally will discover that scholars of the worlds of the Bible and Late Antiquity have much to offer them.
