Access Rights Inheritance in Information Systems Controlled by Metadata

All information systems have to be protected. As the number of information objects and the number of users increase the task of information system’s protection becomes more difficult. One of the most difficult problems is access rights assignment. This paper describes the graph model of access rights inheritance. This model takes into account relations and dependences between different objects and between different users. The model can be implemented in the information systems controlled by the metadata, describing information objects and connections between them, such as the systems based on CASE-technology METAS.

A State of Minds : Canada in the Information Era (Working Paper 10)

Globalization and the knowledge/ information revolution are signalling the advent of a new societal order, one with profound and pervasive implications for citizens, for markets, for governments and, therefore, for public policy. This new global order is a truly remarkable watershed in the annals of human history and, as is the case with all such great transformations, it carries with it both enormous opportunities and daunting challenges. Building on my 1999 Mabel Timlin Lecture at the University of Saskatchewan, I want to share with you my perspectives on the nature of some of these opportunities and challenges, with an eye toward drawing out the implications for the evolution of the Canadian society and economy.

A produção social do conhecimento na sociedade da informação

This work is an approach to some problems and challenges to a contemporary social construction of knowledge from some paradoxes generated around the concepts of knowledge, information, culture and information society. The article proposes to think over problems about a common sense concept which is that the technologies would automatically release the man from repetitive work and would allow the access to information and knowledge. In this sense, it points out to the importance of cultural mediation and information activities in the field of Information Science.

Society and technological evolution: challenges and opportunities

Starting from the assumption that, the organizational learning process influences, in a positive way, the innovative environment and that it shows positive effects on individual, group and organizational performance, this paper deals with the analysis of companies that provide knowledge-intensive products. Referring to the initial information obtained through an adequate survey that is still being performed since May 2009, the main goal is to identify the ways to an organizational learning, measure its importance and identify the effects on the social and economic development. Our reflexion study handles two Portuguese knowledge-rich-organizations, based on the metropolitan area of Lisbon. The paper has the following methodological structure: in the first chapter we will make a theoretical contextualization about the organizational learning; in the second chapter we will handle the data recovered using the SPSS statistics software and, afterwards, presenting the main results. Finally, starting from the main conclusions achieved, we willgive clues to an ongoing reflection.

Dificuldades de prendizagem na quisição da leitura: um estudo de caso

A aprendizagem da leitura e da escrita consiste num dos maiores desafios que as crianças têm de enfrentar no início da sua escolarização. Conseguir vencer esse desafio dá-lhes a oportunidade de se tornarem cidadãos livres, autónomos e informados (Silva, 2003). Contudo, o ato de ler pode tornar-se um desafio árduo de atingir, com muitas dificuldades pelo meio, podendo exigir bastante sensibilidade, conhecimento, informação e até arte por parte de quem ensina. Sabemos que a informação não chega a todos os alunos da mesma forma. Uns necessitam de mais tempo para aprender, mais oportunidades, outras estratégias. Este trabalho teve como objetivo principal encontrar um conjunto de estratégias que fossem ao encontro das necessidades educativas de uma aluna com oito anos de idade que revela grandes dificuldades na aquisição desta competência. Numa primeira fase da intervenção foram aplicadas provas diagnósticas para aferir as aquisições que a aluna já tinha feito de modo a delinear uma intervenção eficaz e motivadora que fosse ao encontro das suas necessidades. A intervenção baseou-se na aplicação de um método multissensorial que trabalhasse todos os mecanismos inerentes ao ato de ler. Esperava-se que com esta intervenção a aluna lesse e escrevesse pequenas frases, tendo adquirido a base para o desenvolvimento da leitura. Os resultados obtidos foram positivos, sendo que os fonemas trabalhados foram adquiridos, tendo chegado a aluna ao fim da intervenção a ler frases simples

Hiljaisen tiedonja osaamisen siirtäminen yksilöltä tiimille tietotekniikka- ja telekommunikaatioalalla

Tässä diplomityössä tarkastellaan hiljaisen tiedon ja osaamisen siirtämistä yksilöltä tiimille tietotekniikka- ja telekommunikaatioalalla (IT-ala). Tarkoitus on kehittää systemaattinen tiedonsiirtämismenetelmä, johon kuuluu uusi työskentelytapa ja teknisenä työkaluna tietämyskannan käyttö. Teoriaosuudessa tarkastellaan tiedon määritelmää ja eri olomuotoja. Pohditaan hiljaisen ja määrällisen tiedon eroa. Tutkitaan miten tiedonsiirtäminen tapahtuu ja mitä haasteita siinä voi esiintyä. Käsitellään oppimissykli ja tietämyskanta. Empiriaosuudessa tutkitaan neljää tiimiä IT-alalta. Tiimit ovat luonteeltaan ja toiminnaltaan erilaisia. Tutkitaan mitä tiedonsiirtohaasteita niissä on. Samalla pohditaan onko tiiminrakenteella merkitystä tiedonsiirtämisen kannalta. Empiiriset tulokset osoittavat, että tiimin rakenne itsestään ei ratkaise tiedonsiirtämishaasteita. Tulosten perusteella suositellaan systemaattista tiedonsiirtämistä. Avuksi kannattaa ottaa käyttöön tietämyskanta, tarkemmin wiki ja blogi.

Asiantuntijatiedon hyödyntämisen edellytykset Tiehallinnossa

Tutkimuksessa tarkasteltiin tietojohtamista sekä tiedon hyödyntämisen edellytyksiä asiantuntijaorganisaatiossa tietämysperusteisen organisaationäkemyksen näkökulmasta. Tutkimuksen tavoitteena oli selvittää tietojohtamisen käyttömahdollisuuksia sekä asiantuntijoiden tietämyksen johtamista asiantuntijatiedon hyödyntämisen edellytysten parantamisessa Tiehallinnossa.

Ammatillisen osaamisen tukeminen muuttuvissa toimintaympäristöissä : tutkimus ikääntyvien työntekijöiden näkökulmasta

The purpose of the study was to describe the experiences of received support of aging employees and their work related self-image in changing working environments. Firstly, theaim was to discover how the support from organisations and leaders was verified. Secondly, the aim was to get answers how employees experienced themselves as workers and as learners in the current work context. Thirdly, the aim was to compare different knowledge information stages and company cultures and how they have influenced the experiences of professional competence development among aging employees. In addition the education- and career backgrounds were investigated to gain more understanding of their role in experiencing support and relation to the occupational self-image. The theoretical frame of reference of this researchis multidisciplinary. The theoretical part focuses on the meaning of work for human being from a sociological, late-modern perspective. On the other hand it examines the ageing process from a physiological and also from a perspective of age discrimination and life control. The occupational selfimage and the strength of motivation has an effect on learning in working life which is crucial and firmpart individual trajectories. According to the theoretical review company culture, leadership and especially the managers' role as a creator of a learning atmosphere are increasingly critical for aging adults' learning when the role of informal work-based learning is increasing. The empirical data was collected with aquestionnaire and interviews, which were carried out in May to October 2001. The data consists of 263 respondents of which further eight persons were interviewed. All respondents were over the age of 45 and represented all levels of their organisations in an IT-technology firm and a chemical industry plant. The central findings in this research show that the aging adults have experienced that theemployers do care about the development of their occupational skills. On the other hand there are fewer concrete activities to reveal this support. There is anobvious disproportion between the expressed aims and the realisation of the activities. Signs of age discrimination are few. The style of management has becomemore supporting for self directed activities which are seen to support adults learning. Higher education and individual activity to seek possibilities to learnwere encouraging the development of occupational skills. Age itself was not a crucial aspect when comparing the experiences among younger (45-54 years) and older (55-64 years) groups. Job satisfaction and professional self esteem seemed tobe considerably strong. The individual characteristics were more important elements in developing occupational skills than the age. The degree of anxiety at work was low. In addition among the older group the strong feeling of coherence and the occupational self image were significant for supporting the professional competence. The motivation to learn was also stable. Among the seniors there was some slight evidence of declining motivation. In the IT-firm the support was experienced stronger for aging employees than in the chemical industry plant. Thosewho had experienced support in the chemical industry plant had higher educational background than the others. In IT-firm they also experienced more support from the manager than in the chemical industry plant. The results show that it is more likely that the differences are caused mostly by the stage of information intensity and the character of company culture which is determined by the activities. IT-business demands constantly accommodation to changes and the chemical industry plant which is representing more traditional business field, where the atmosphere of learning is determined by the traditions of company culture, the changes are carried out slowly.

Attribute exploration with background implications and exceptions

Implications between attributes can represent knowledge about objects in a specified context. This knowledge representation is especially useful when it is not possible to list all specified objects. Attribute exploration is a tool of formal concept analysis that supports the acquisition of this knowledge. For a specified context this interactive procedure determines a miminal list of valid implications between attributes of this context together with a list of objects which are counterexamples for all implications not valid in the context. This paper describes how the exploration can be modified such that it determines a mimimal set of implications that fills the gap between previously given implications (called background implications) and all valid implications. The list of implications can be simplified further if exceptions are allowed for the implications.
