This study investigated bidirectional links between the quality of teacher–child relationships and children’s interest and pre-academic skills in literacy and math. Furthermore, differences in the patterns of bidirectionality between boys and girls were explored. Participants were 461 Finnish kindergarteners (6-year-olds) and their teachers (n = 48). Teachers reported their closeness and conflict with each child twice throughout the kindergarten year. Children rated their interest in literacy and math, and were tested on their pre-academic skills. Cross-lagged path models indicated that teacher-perceived conflict predicted lower interest and pre-academic skills in both literacy and math. Results were similar for boys and girls. Implications for reducing conflictual patterns of relationships, together with promoting other factors, are discussed. 相似文献

Because in recent years the universities of Finland have had to rely more on regional than on national support, the University of Turku, which was created in 1920 to serve a national purpose, had to redirect the scope of its activities to its region. However, this region is the most important economic area of Finland outside the capital area and can thus provide many opportunities for the university. A more targeted central management at the university evaluated the external impact of the institution and decided to focus on the biosciences, cultural interactions and integration, mathematics and mathematical methods, learning and teaching, information and communication technology, materials research, and collaboration in the Baltic Sea zone as areas of regional outreach and collaboration. The latter takes place in many ways. In particular, collaboration in science takes place through the BioCity Turku organization, an umbrella organization for research in cell and molecular biology, the Turku Center for Computer Science, and the Turku Science Park. Thus the University of Turku is helping to unlock the resources of its region, and the region supports its university in a number of ways. 相似文献

We develop a deductive data model for concept-based query expansion. It is based on three abstraction levels: the conceptual, linguistic and string levels. Concepts and relationships among them are represented at the conceptual level. The linguistic level gives natural language expressions for concepts. Each expression has one or more matching patterns at the string level. The models specify the matching of the expression in database indices built in varying ways. The data model supports a declarative concept-based query expansion and formulation tool, the ExpansionTool, for heterogeneous IR system environments. Conceptual expansion is implemented by a novel intelligent operator for traversing transitive relationships among cyclic concept networks. The number of expansion links followed, their types, and weights can be used to control expansion. A sample empirical experiment illustrating the use of the ExpansionTool in IR experiments is presented. 相似文献

This article examines anti-racist strategies employed in Finnish children’s literature. The examples from four stories illustrate that certain physical characteristics and cultural markers can become strong signifiers of nationality, that is Finnishness. The characters in these stories have to cope with experiences of exclusion and loneliness before the people around them learn that difference and diversity do not change the fact that all humans are worth the same. However, the paper argues that the intended positive outcome of books with a strong anti-racist agenda threatens to be lost as heavily accentuated moral lessons often become counterproductive. The paper demonstrates some of the changes that have taken place in Finnish children’s literature during the past two decades and addresses significant cultural and societal issues that affect children’s everyday lives. 相似文献

This study introduces a novel framework for evaluating passage and XML retrieval. The framework focuses on a user’s effort
to localize relevant content in a result document. Measuring the effort is based on a system guided reading order of documents.
The effort is calculated as the quantity of text the user is expected to browse through. More specifically, this study seeks
evaluation metrics for retrieval methods following a specific fetch and browse approach, where in the fetch phase documents
are ranked in decreasing order according to their document score, like in document retrieval. In the browse phase, for each
retrieved document, a set of non-overlapping passages representing the relevant text within the document is retrieved. In
other words, the passages of the document are re-organized, so that the best matching passages are read first in sequential
order. We introduce an application scenario motivating the framework, and propose sample metrics based on the framework. These
metrics give a basis for the comparison of effectiveness between traditional document retrieval and passage/XML retrieval
and illuminate the benefit of passage/XML retrieval. 相似文献

This study examines the use of an ontology as a search tool. Sixteen subjects created queries using Concept-based Information
Retrieval Interface (CIRI) and a regular baseline IR interface. The simulated work task method was used to make the searching
situations realistic. Subjects’ search experiences, queries and search results were examined. The numbers of search concepts
and keys, as well as their overlap in the queries were investigated. The effectiveness of the CIRI and baseline queries was
compared. An Ontology Index (OI) was calculated for all search tasks and the correlation between the OI and the overlap of
search concepts and keys in queries was investigated. The number of search keys and concepts was higher in CIRI queries than
in baseline interface queries. Also the overlap of search keys was higher among CIRI users than among baseline users. These
both findings are due to CIRI’s expansion feature. There was no clear correlation between OI and overlap of search concepts
and keys. The search results were evaluated with generalised precision and recall, and relevance scores based on individual
relevance assessments. The baseline interface queries performed better in all comparisons, but the difference was statistically
significant only in relevance scores based on individual relevance assessments. 相似文献

This paper deals with Swedish full text retrieval and the problem of morphological variation of query terms in the document database. The effects of combination of indexing strategies with query terms on retrieval effectiveness were studied. Three of five tested combinations involved indexing strategies that used conflation, in the form of normalization. Further, two of these three combinations used indexing strategies that employed compound splitting. Normalization and compound splitting were performed by SWETWOL, a morphological analyzer for the Swedish language. A fourth combination attempted to group related terms by right hand truncation of query terms. The four combinations were compared to each other and to a baseline combination, where no attempt was made to counteract the problem of morphological variation of query terms in the document database. The five combinations were evaluated under six different user scenarios, where each scenario simulated a certain user type. The four alternative combinations outperformed the baseline, for each user scenario. The truncation combination had the best performance under each user scenario. The main conclusion of the paper is that normalization and right hand truncation (performed by a search expert) enhanced retrieval effectiveness in comparison to the baseline. The performance of the three combinations of indexing strategies with query terms based on normalization was not far below the performance of the truncation combination. 相似文献
