This paper considers the role and the aim of education in Rousseau's thinking generally. The position of education is a search between nature and society. Education is the medium between nature and society, and its aim is to undermine the threat of the natural intentions of man's actions to preserve his being and seeking for happiness turning into pathologies of society, which was the main target of Rousseau's critic of society. Achievement of this aim means the recovery of the natural harmony of man. The main concern of this paper is to discuss the solution to this as introduced in E´mile. This is autarchy, where a man's desires and capacities to fulfil those desires are in equilibrium. 相似文献

Word form normalization through lemmatization or stemming is a standard procedure in information retrieval because morphological variation needs to be accounted for and several languages are morphologically non-trivial. Lemmatization is effective but often requires expensive resources. Stemming is also effective in most contexts, generally almost as good as lemmatization and typically much less expensive; besides it also has a query expansion effect. However, in both approaches the idea is to turn many inflectional word forms to a single lemma or stem both in the database index and in queries. This means extra effort in creating database indexes. In this paper we take an opposite approach: we leave the database index un-normalized and enrich the queries to cover for surface form variation of keywords. A potential penalty of the approach would be long queries and slow processing. However, we show that it only matters to cover a negligible number of possible surface forms even in morphologically complex languages to arrive at a performance that is almost as good as that delivered by stemming or lemmatization. Moreover, we show that, at least for typical test collections, it only matters to cover nouns and adjectives in queries. Furthermore, we show that our findings are particularly good for short queries that resemble normal searches of web users. Our approach is called FCG (for Frequent Case (form) Generation). It can be relatively easily implemented for Latin/Greek/Cyrillic alphabet languages by examining their (typically very skewed) nominal form statistics in a small text sample and by creating surface form generators for the 3–9 most frequent forms. We demonstrate the potential of our FCG approach for several languages of varying morphological complexity: Swedish, German, Russian, and Finnish in well-known test collections. Applications include in particular Web IR in languages poor in morphological resources. 相似文献

Many operational IR indexes are non-normalized, i.e. no lemmatization or stemming techniques, etc. have been employed in indexing. This poses a challenge for dictionary-based cross-language retrieval (CLIR), because translations are mostly lemmas. In this study, we face the challenge of dictionary-based CLIR in a non-normalized index. We test two optional approaches: FCG (Frequent Case Generation) and s-gramming. The idea of FCG is to automatically generate the most frequent inflected forms for a given lemma. FCG has been tested in monolingual retrieval and has been shown to be a good method for inflected retrieval, especially for highly inflected languages. S-gramming is an approximate string matching technique (an extension of n-gramming). The language pairs in our tests were English–Finnish, English–Swedish, Swedish–Finnish and Finnish–Swedish. Both our approaches performed quite well, but the results varied depending on the language pair. S-gramming and FCG performed quite equally in all the other language pairs except Finnish–Swedish, where s-gramming outperformed FCG. 相似文献

Researchers from Mid Sweden University and Kalmar University organised surveys on reading skills in Swedish municipalities. This paper will focus on the surveys made in four municipalities between 2002 and 2007. All students in grade 8 in these four municipalities participated in the surveys--in total 16,287 students. These surveys included a reading test for the students and information about the students collected from the teachers, including participation in instruction in Swedish as a second language and in their mother tongues. Students of immigrant origin in Sweden are offered the possibility to participate in instruction in Swedish as a second language and in instruction in the student＇s mother tongue. No obvious trends over time in the participation in Swedish as a second language and mother tongue instruction were found in the four municipalities on the tests we gave, in spite of national trends. There was no difference in results on the reading tests in Swedish between those students who participated in mother tongue instruction and those who did not, but there was a difference in test results between those who participated in Swedish as a second language and those who did not. Those who did not participate （in Swedish as a second language instruction） did, on average, score higher on the test. When different language groups are compared, it can be noted that a majority in all groups of immigrant students neither participate in Swedish as a second language nor in mother tongue instruction. However, there are important differences between boys and girls and between language groups. Girls seemed to be more willing than boys to participate in voluntary mother tongue instruction, while boys more often than girls had to participate in compulsory lessons in Swedish as a second language. 相似文献

The aim of this article is to analyse how journalists' professional identity is related to their attitude towards PR. The focus is how—and to what extent—journalistic ideology, organizational belonging and the individual's social position influence journalists' perception that other journalists working with PR lower the trustworthiness of journalism. The analyses rest on data from the Swedish Journalist Survey 2011, which is a national representative survey of Swedish journalists. The results show that journalists in general embrace a hostile attitude towards journalists who start working as PR practitioners. However, those who have worked as a journalist for fewer years or have journalistic ideals promoting the amusement function of journalism, or have worked as a freelance, or been employed in an organization producing newsletters, as well as female journalists, weaken this posture. The article concludes with a discussion on how the results could be understood in relation to recent changes in journalism's power and prerequisites, and how a professional identity might function as a form of resistance. 相似文献
