Kontrollerad vokabulär eller naturligt språk? En empirisk studie.

The question whether controlled vocabulary or natural language free-text terms is the most effective search strategy has occupied researchers in LIS for many decades. This Masters thesis is an empirical study which aims to compare these two search strategies in LISA Library and Information Science Abstracts, an online bibliographic database. 22 topics from the discipline of Library and Information Science were constructed and out of each topic one query for each search strategy was formed. Queries in natural language were formed with terms from different sources, for example dictionaries, while queries in controlled vocabulary were built with terms from LISAs electronic thesaurus. The measures used in this study were precision, relative recall pooling method and overlap.

Fotoindexering på Jämtlands läns museum

The aim of this thesis is to describe the subject indexing of images performed at the provincial museum of Jämtland and to evaluate the inter-indexer consistency at the museum. The main questions are: How are photographs indexed in the database SOFIE foto regarding Outline-codes, subject headings and natural language keywords? How does these procedures compare to research and indexing projects? How consistent are the indexers at the museum when choosing Outline-codes, subject headings and natural language keywords? Answers are sought by reading articles about classification, image indexing, indexing language, indexing consistency and by looking at a number of projects attempting to standardise image indexing practice in Sweden. The indexing practice at the museum is also described. In addition a minor inter-indexing consistency study, based on the subject indexing of ten photographs made by five indexers at the museum, is performed.

Grundläggande läs- och skrivinlärning : Är stavelsen en gynnsam arbetseneht?

The aim of this study is to contribute to a better understanding of the syllable as an alternative to the phoneme at the basic reading and writing. This report is based on a qualitative analysis of Håkanstorp school´s approach to the basic reading and writing in class. Their approach to reading and writing is controversial, as it is based on the syllable instead of the phoneme, as usual in the traditional reading and writing. The education result, I have found, is that the syllable leads to a very clear and structured working procedure, which ultimately leads to class teachers being able to work from a diagnostic approach. This structure, with many parts of the course helps educators to clearly follow what level students are at.

In school, pupils learn to critically relate to sources of various texts. In the course of time they also learn how to make references and cite properly. Yet, alarming reports show increasing cheating and plagiarism in colleges and universities. Plagiarism prevention services are used today in Swedish high schools.

Ämnessökningar med kontrollerad vokabulär och naturligt språk: en jämförande studie med felanalys.

The aim of this thesis is to compare the effectivity of using a natural language and a controlled vocabulary when performing subject searches in the bibliographic database LISA Library and Information Science Abstracts. 20 topics were created and for each topic two searches were made, one by using a query formulated with natural language directed to the abstract field and the other one by using a query formulated with descriptors from the thesaurus in LISA directed to the descriptor field. The average relative recall amounted to 64,8% for the AB-queries and 54% for the DE-queries. Failure analysis showed that the majority of the relevant documents not retrieved by AB-queries could have been retrieved with other query terms, such as synonyms. In a natural language there are many different ways of expressing a topic, and this tends to have a negative effect on retrieval effectivity.

NATURMINNENS F?RVALTNING OCH SKYDD: Inventering i V?stra G?taland

Natural monuments are natural objects with special protection due to their high natural value or cultural significance. The natural value is determined by the occurrence of signal species found on and near the natural monument. The law surrounding natural monuments has evolved a lot since the first ones were declared, and today the title natural monument can be replaced with the title tree with high conservation value. The title has come later and can sometimes overlap natural monument. Some natural monuments lack the qualities required to be classified as a natural monument or a tree with high conservation value, but have a cultural importance.

Naturvetenskap i förskolan : Spelar utbildning och intresse roll för hur man arbetar med naturvetenskap i förskolan?

How do you see on natural science within preschool? Does education and interest play a role for how the educationalist works with natural science? And is the children?s interest for natural science affected by the educationalist, what does the educationalist think himself? These questions have I under my teachers training and under deputyship in preschool asked myself and these questions lies to behalf for my investigation. I interviewed five educationalists on different preschools for my investigation.My investigation resulted in that I have been able to see a certain conjunction between how you work with natural science in preschool and the educationalist education or interest. What also plays a role is that you often associate natural science with knowledge of nature. The educationalist seems overall positive to natural science, but depending of a lack of knowledge it feels strange and difficult.

Förhållandet mellan barns populära status, individuella bearbetningsstil och arbetsminneskapacitet

This study was conducted to investigate the relationship between perceived popularity, social information processing and working memory. With the intentions of examining popularity 209 (98 female, 111 male) children in second and fourth grade were presented with a roster of their classmates and were to nominate whom they liked and whom they disliked. To study working memory capacity a working memory test, that places demands on the participant to work both with and store the given information, was used. To examine children's cognitive processing of empathy-provoking information a cognitive appraisal interview was conducted. The results imply (a) that working memory increases with age, (b) that there is a weak relation between working memory capacity and popularity, and between popularity and cognitive processing styles and (c) that there are some strong correlations between working memory and cognitive processing styles..

Utepedagogik, drama och bild : språkutvecklande arbetsmetoder

The purpose of this essay is to examine how out-pedagogy, drama and art can be used as means of promoting language development of bi-and multi-language learners, and to show what benefits these three methods offer to children of year three of an elementary school in Stockholm City. This is a small survey of work-style and the results are based on observations and interviews with five teachers which included three class teachers, one resource teacher and one other language teacher and it was carried out two full days of observations in both classroom and outdoor environment. In this work, I note how out-pedagogy, drama and art can help bi- and multilingual children develop language. My study shows, in accordance with the respondents interviewed, as well as research in general that out-pedagogy, drama and art is language development practices. They argue that out-pedagogy and the aesthetic elements promote language development of bi- and multilingual children in different ways and complements the traditional approach.

The aim of the present study was to investigate response time variations in tasks for assessment of high level language functions and how response time is related to education, age and gender. Response time is defined as the time to complete a task after it has been presented. 103 subjects, aged 20 to 80 years, were tested with the Assessment of Subtle Language Disorders, Sentence analysis and Morphological completion. The subtest Comprehension of ambiguous sentences showed the longest response time and Morphological completion the shortest. Correlations were found between increasing age and longer response time for Comprehension of metaphors and between education and response time for several subtests.
