Subjektivne stimulacije u funkciji razvoja postularnog refleksnog mehanizma kod djeteta s cerebralnom paralizom

. It is widely accepted that the consistency of adaptive interfaces is crucial for their usability. Many threats for consistency in adaptive applications have been reported in the literature so far (e.g., consistency of adaptation methods and techniques, consistency of the user model). In this paper we argue that many, if not all, user modeling systems that have been developed so far are substantially threatening consistency by offering no adequate means for communicating consistency contexts. This is especially the case for user modeling servers, which are supposed to serve several applications in parallel. In order to prevent consistency problems in user modeling systems, we introduce basic concepts and techniques from transaction management. User modeling systems that adhere to the principles of transaction management can be expected to provide a reliable source of user information for adaptive applications, especially in real world settings. Introduction One of the cen..

Alteration of the embryo transcriptome of hexaploid winter wheat (Triticum aestivum cv. Mercia) during maturation and germination

Grain dormancy and germination are areas of biology that are of considerable interest to the cereal community. We have used a 9,155-feature wheat unigene cDNA microarray resource to investigate changes in the wheat embryo transcriptome during late grain development and maturation and during the first 48 h of postimbibition germination. In the embryo 392 mRNAs accumulated by twofold or greater over the time course from 21 days postanthesis (dpa) to 40 dpa and on through 1 and 2 days postgermination. These included mRNAs encoding proteins involved in amino acid biosynthesis and metabolism, cell division and subsequent cell development, signal transduction, lipid metabolism, energy production, protein turnover, respiration, initiation of transcription, initiation of translation and ribosomal composition. A number of mRNAs encoding proteins of unknown function also accumulated over the time course. Conversely 163 sequences showed decreases of twofold or greater over the time course. A small number of mRNAs also showed rapid accumulation specifically during the first 48 h of germination. We also examined alterations in the accumulation of transcripts encoding proteins involved in abscisic acid signalling. Thus, we describe changes in the level of transcripts encoding wheat Viviparous 1 (Vp1) and other interacting proteins. Interestingly, the transcript encoding wheat Viviparous-interacting protein 1 showed a pattern of accumulation that correlates inversely with germination. Our data suggests that the majority of the transcripts required for germination accumulate in the embryo prior to germination and we discuss the implications of these findings with regard to manipulation of germination in wheat

Integrating User Modeling into Information Extraction: The UMIE Prototype

. This paper introduces user modeling into the process of information extraction. It presents the user modeling prototype (UMIE) that we developed during the research project ECRAN. UMIE takes as input information extracted from corpora and adapts it according to the user's interests in domain categories. 1 Introduction Text-based information systems deliver to users information derived from texts. Information re- trieval systems, based on the user's query, retrieve relevant documents from a relatively static set of documents. Information filtering systems examine a dynamic stream of documents and display only those which are relevant to the keywords profile of a user. Information extraction systems extract facts from documents in a domain. The extracted facts fill the pre-defined templates for the specific domain. Today's overload of information often makes information systems ineffective. What is important is to deliver to the user information according to his needs, interests, exp..

Personis: A server for user models

Abstract. A core element of an adaptive hypertext systems is the user model. This paper describes Personis, a user model server. We describe the architecture, design and implementation. We also describe the way that it is intended to operate in conjunction with the rest of an adaptive hypertext system. A distinctive aspect of the Personis user model server follows from our concern for making adaptive systems scrutable: these enable users to see the details of the information held about them, the processes used to gather it and the way that it is used to personalise an adaptive hypertext. We describe how the architecture supports this. The paper describes our evaluations of the current server. These indicate that the approach and implementation provide a workable server for small to medium sized user collections of information needed to adapt the hypertext
