The relational database model was defined in the 1970?s and is the dominating database type today.  The main difference between data from a relational database and a hierarchical data structure is that the relational database stores records in tables. The records have no particular order, but can include links in terms of relationships with other records. A hierarchical structure organizes data in the form of a tree structure  and  can for an example be found in organizational structures in which different levels involves different responsibilities. If the data stored in a relational database is to be presented in a hierarchically, a conversion of the data structure is required. The intention of this paper is to describe how such a conversion can be performed.  To investigate the conversion methods, case studies has been conducted on the basis of a specific organization?s hierarchical structure.

The purpose of the study is to analyze what conditions the specific company provides employees to enable organizational learning. To clarify the framing of the study a few quastions has been specified to narrow the issu. The questions that has been used are: what opportunities does the company creat to enable organizational learning and how does the emplyees contribute to organizational learning.In the search of knowledge to the previously questions this study becames a qualitative study with an ethnographic approach based on observations and interviews. This method gives the knowledge that makes us understand the actions that takes place in the oraganization and the shared image the oraganization provides. An understanding for the employees and the organization has been achived after compiling the empirical material from observation notes and transcripts from the interviewsIn the work whit the analysis the empirical material based on transcripts and observation notes has been the main material.

The aim of this essay is to get knowledge and to evaluate if the media student has equal or evenbetter knowledge of information technology (IT) than his/her teacher. Today the student of IToften has knowledge of hard ware and soft ware sometimes even unknown to the teacher. Themain reason for this might be that IT hitherto has played no prominent part at the institutes ofteacher education. Continuing further education of IT for teachers is also eligible as IT still is arather new subject on the time table.To adopt an empiric approach to the problem I have used trough interviewing and questions bothteachers and students at two upper secondary schools in the province of Värmland. The schoolsare called ?A? and ?B? in my investigation.Does the teacher have enough knowledge to give the student relevant knowledge concerninghard ware as well as soft ware to handle the computer and to utilize its possibilities? How can theteacher act to comply with the students? claims and demands?IT-knowledge can be expressed in a complicated way but I have limited my investigation to therole of the teacher and how he/she manages to teach and instruct concerning a selected numberof soft ware and how the students evaluate their own knowledge compared to that of the teacher.My investigation shows that the teachers consider their knowledge relevant for their task asinstructors and teachers.

The aim of this study was to examine what knowledge social workers express about home visits in child welfare investigations and how they know what to do. Sixteen social workers who work with social investigations concerning children were asked to discuss the topic home visit in three focus group interviews in three different municipalities in southern Sweden. The social workers in our focus group interviews mainly discussed the purpose of the home visit, what social workers do during home visits and furthermore their opinions about guidelines and policy documents regarding the home visit.  To get an understanding of what type of knowledge is the basis for social workers use of the home visit, we used Polanyi's concept of 'tacit knowing' as well as the Aristotelian theory of knowledge containing three forms of knowledge, that is, episteme, techne and fronesis. We found that the displaying of ?tacit knowing? was a consistent feature in all groups, as they had difficulty expressing their knowledge use.

National libraries hold large, valuable repositories of often unique materials. How can we ensure that the knowledge is accessible without endangering the materials that hold the knowledge? Digital preservation is meant to solve this problem. With more and more material being accessible digitally, users are expected to do more and more of the finding on their own, instead of being guided by librarians. What kind of knowledge do the librarians have, that cannot be mediated through a system? How is the knowledge of experienced librarians passed on to new librarians? What is the difference between physical and digital materials? I have interviewed senior and junior librarians of Det Kongelige Bibliotek in Copenhagen, Nasjonalbiblioteket in Oslo, the National Library in Helsinki, and Kungliga Biblioteket in Stockholm to learn about their journey to knowledge of their collections.

A research review shedding light over organizational cultureand its affect on knowledge sharing. The purpose of thereview was to give an overview of the current researchmeanwhile answering the research questions how and whyorganizational culture influences knowledge sharing.Through careful selection of articles, from Journal ofKnowledge Management, a review of the material led toareas of emphasis being identified: motivation, trust,organizational structure, management, communication andrewards. For each area of emphasis the results from thechosen articles were presented and analyzed, leading toconclusions that the how and why of organizational culture?sinfluence is due to mainly individual motivational factorsamongst staff. This implies that organizations need to keepfocus on the psychological factors affected by organizationalculture when looking to make knowledge sharing moreefficient.

This thesis presents the implementation of a knowledge base system for rough sets [Paw92]within the logic programming framework. The combination of rough set theory with logic programming is a novel approach. The presented implementation serves as a prototype system for the ideas presented in [VDM03a, VDM03b]. The system is available at "http://www.ida.liu.se/rkbs". The presented language for describing knowledge in the rough knowledge base caters for implicit definition of rough sets by combining different regions (e.g.

The aim of this study is to investigate how new knowledge, discovered and translated by the archaeologist, is transferred to the public by examining the question posed to the archaeologist by ?la?nsstyrelsen,? the county administration office.Since there can be no mediation of knowledge without an understanding of its perception, I pay a visit to the cognitive sciences in order to answer what knowledge is and how it functions in regards to contract archaeological results.I argue that the current structure of mediation, in regards to archaeological knowledge, is in need of the same quality control that is demanded by the contractors in regards to standard archaeological procedures. When presenting archaeology to the public, consideration needs to be paid to the different targets groups of society. The importance of national directions rather than regional translations for mediation of archaeology is stressed by the author. This needs to be carried out through a change of the questions posed to the contracted archaeologists by the county administration in their ?fo?rfra?gningsunderlag,? the order specification for archaeological investigations. .

A cars powertrain consists of everything that is needed for its propulsion. The components in the driveline that transfer the power from the engine to the driven wheels are not absolutely stiff, hence they will wind up due to the torque and act as torsion springs. If you suddenly demand a bigger torque by stepping on the accelerator pedal, a so called tip in manoeuvre, and that torque is acquired from the engine as quickly as possible, the driveline will not be able to transfer that fast torque change due to its weakness and as a result it will start to oscillate. These oscillations will be transferred to the driven wheels and make the car to accelerate jerkily which will be experienced as uncomfortable by the passengers. Furthermore, there is a backlash in the driveline that will make the weakness in the driveline even more excited than it should have been if the backlash did not existed.To avoid too big problems with these oscillations there is a control system that controls the demanded torque.

Within the near future Sweden will be facing a large number of successions of ownership  within the agriculture and forestry sector, which is why it is important to acknowledge the question of alternatives for transfer of ownership. The purpose of this thesis is therefore to analyze the existing law as well as the various options for how to transfer the ownership concerning succession of ownership within family-owned agriculture and forestry businesses. This thesis pays particular attention to the complexity of problems that refer to joint ownerships and the great importance of the emotional questions that arise when a succession of ownership is being implemented.A succession of ownership can be planned as well as unplanned. When implemented through inheritance the transfer to the younger generation is unplanned. There are several effects of an unplanned succession of ownership and these effects can be harmful for the company as well as the family.

The aim of this thesis is to examine librarians' view on the knowledge and competence required at a small public library and how they look upon their education in retrospect. Library education in the 1970's and 1980's was mainly practical, a vocational training, but since 1995 the education results in an academic degree in Library & Information Science. Due to this, we focus on the ongoing generation shift in Swedish libraries as an aspect of knowledge and education. The empirical study is based on interviews with librarians working in minor public libraries. The informants form two groups, based on their education; ?old? ones and ?new? ones.

Because of among other things the globalization and a focus on core competencies knowledge has become very important for the companies of today, especially for research-intensive companies. The problem is that the companies become more sensitive to how knowledge is created and spread, that is, how organizational knowledge is created. Especially sensitive are companies who are small, young and research-intensive. The purpose with this thesis is to explore how organizational knowledge is created in small, young and research intensive companies.The theory is based on a five-phase model of organizational knowledge creation and four modes of knowledge conversion described by Nonaka and Takeuchi (1995). These concepts constitute the foundation of the analytical model used in the thesis.The study is carried out by qualitative, highly structured interviews with low standardization.

I sjukvården världen över tas dagligen tusentals röntgenbilder. Användningsområdena är många, men i de flesta fall är syftet att i något avseende avgöra patientens hälsa. Bilderna utvärderas av läkare för att patienten ska få rätt diagnos. För att läkaren ska kunna göra en korrekt bedömning av bilden och därmed ge patienten den behandling som situationen kräver måste bilden vara rättvisande och vara av sådan kvalitet att alla viktiga detaljer går att urskilja. Bildkvalitet är ett ganska diffust begrepp och ofta används subjektiva bedömningsmetoder för att bestämma ifall en bild är bra eller dålig.

In this thesis the core of the nursing professional skill will be portrayed through the opportunities of the essay writing. Thus the tacit knowledge, which is at the verge of erosion in a zeitgeist where medical care shall be cost-efficient and where development is mainly based on scientific research, will be articulated. Scientific articulation of knowledge has gained increasing importance on the expense of the practical knowledge. Healthcare professional skill requires a refind ability of judgment, which absorbs its nourishment from both scientific knowledge and the proven proficiency expertise.Professional skill expresses itselfs through action, especially through the acting in unexpected incident. Experience is developed into knowledge through reflection.

This Master of Science thesis project handles issues around managing data from the digital tachographsystem. European legislation states that companies must download the data of the digital tachograph systemand store it for at least one year for control purposes. The system stores data on the vehicle unit located inthe driving compartment and on smart cards personal for each driver.Acquiring data from the previous analogue tachograph was done instantaneously since the data wasphysically printed to a circular paper chart when driving. To acquire data from the digital system one mustperform a download from the vehicle unit and later transfer it to some form of backup solution for longterm storage. Data must also be downloaded from the driver smart cards.Download of data from the vehicle unit is the most time consuming task and may take up to 30minutes pervehicle.
