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 aim of this thesis is to investigate which the main determinants of capital structure in Swedish listed firms are and to identify which incentives lies behind managers choice of capital structure determinants. Further, the study investigates whether the Post Keynesian theory and theories which incorporate behavioral aspects can be used to explain the capital structure decisions or if the traditional Neoclassical theory give an better explanation. We have used a qualitative method to analyze the determinants of capital structure and the managers incentives behind capital structure decision. We conducted a survey which was sent to 83 Chief Financial Managers and financial executives in Swedish firms listed on Mid Cap or Large Cap. The questionnaire was on-line which enabled for the respondents to quickly and convenient respond.

The purpose of this thesis is to test whether firms have target capital structure, and if so with what speed they adjust toward this target. Findings that support this purpose are also in line with the trade off theory. One of the key elements of this thesis is the method used, which successfully enables fulfilling the purpose. The panel data method captures the data characteristics of the cross sectional and time series dimension. By using this approach the dynamic effects of capital structure can be studied, thus if there actually is an adjustment towards a target the speed can be estimated.

AbstractThe purpose of this essay is to study in what way teachers in preschool work with pupils enabling them to gain influence and involvement in their learning.Influence means being able to make your voice heard which is an important component of a democratic society. Involvement is about being part of a community in which everyone is welcomed regardless of beliefs and opinions. Several of today's researchers believe that learning occurs in interaction between people. Teachers providing meaningful assignments to pupils, they become more motivated to learn.The study is based on observations of how teachers work with influence and involvement in controlled sessions, and interpretations of them. My results show that children become involved in their learning when they are confronted with a variety of pedagogical approaches to learning.

To describe your profession can sometimes be hard. Everyone knows what a music teacher is and what her work includes. But what about a eurhythmic teacher - who knows what she does? By experience my answer is: not many. Inthis essay I have outlined differences in method and lecture planning between a eurhythmic and a music teacher, to be able to find out the answer to my research question - what a eurhythmic teacher can contribute to the school subject music.I chose an observation research where I observed a mixed class with children from fourth and fifth grade.

During the autumn of 2008 I obtained office experience by working at the local government of Örnsköldsvik. I started working on the district green plan of the green structure and that led to the work of this exam paper. The purpose of this exam paper has been to define some standpoints for the green structure of the local government district of Örnsköldsvik. I have used both a larger and a smaller scale to obtain a wide a perspective as possible of the green structure. The larger scale gives an overall view of the whole municipality while the smaller scale is found in the study of the two local areas Centrum and Domsjö. For the local government planning to be able to obtain an agreeable level of verdure to the residents it is necessary that the green structure is brought up on the agenda.

This master thesis concerns whether Swedish non-financial listed firms act in accordance with the optimal capital structure theory and/or pecking order theory. The examined period is 1998-2004 and we discover that Swedish companies neither follow optimal capital structure theory nor pecking order theory. From our results we conclude that there exists no single point of the capital structure which is optimal. Rather it seems as if the optimal point lies in-between an interval from 0 to the industry average, where firms tend to be indifferent to their debt-ratios. Our results show that Swedish companies prefer internal financing followed by equity and as last choice debt issuance..

Background: A company?s choice of capital structure is influenced by the access to internal and external capital but also by the opportunities and threats that the management perceives in the environment and the management?s attitude towards risk. How an individual perceives and interpret the environment depends on the cognitive structures, which are shaped by personality, background and earlier experiences. Accordingly cognitive structures can be expected to influence the choice of capital structure. Purpose: Out of a cognitive perspective we intend to study the relationship between the way a company views it?s environment and what capital structure it chooses to have, in order to contribute to an increased understanding about what lies behind a company?s capital structure policy.

The change of the Real property index map has met a lot of resistance in Dalarna.This is the reason that the parcel?s reform has not had the same impact in Dalarnaas in the rest of Sweden. In addition, even ?Laga skifte? (the reformation on propertystructure) was never effected in most areas of Dalarna. This has lead to thatDalarna has a unique property structure with many small and narrow parcels.Some argue, however, that the property structure has been the same for many centuries.The purpose of this thesis is therefore to study how the property structurelooked before ?storskifte? (the reformation on property structure) was done, howit was when äganderättsutredningen (the adjudication), in the 1970s, was accomplished,and finally how the structure looks when land consolidation has been implemented.For the template of the studies, seven different villages were chosen.The basis for the study was comprised of acts for each stage and each village.The study showed that change in property structure has occurred.

Den här studien har genomförts för att undersöka hur en gitarrlektion fungerar över internet och hur den upplevs av dess användare. Undersökningen har genomförts genom att jag och två av mina gitarrelever har utforskat två olika gitarrhemsidor. Vi har tagit lektioner från dessa sidor. Där visas materialet genom video, ljud och med eller utan tabulatur. Därefter har mina elever intervjuats där de bland annat har fått svara på frågor om vad de tyckte om hemsidan, lektionen och lärarens kvalitet och hur det kändes att inte ha en lärare närvarande vid lektionstillfället.

This is an empirical study based on Physical Education and health (PE) teachers' experiences and builds on, for the study, significant literature. The study is about PE teachers? consideration of gender in the assessment as well as in the selection of lesson content. Semi-structured interviews were employed as method for the data collecting process. Four teachers were interviewed, teachers of PE in elementary and upper secondary school with varied length of professional experience and ages.

This study is based on an interest in trying to understand what is needed to ensure that students actually learn in a learning object, in this study equations. Algebra is an area of mathematics in several studies proved to be a stumbling block for many students. Using letters in mathematis is difficult for most students according to research reports and it is also consistent with my own experince as a teacher. The purpose of this study was to seek answers to what in the lesson content and also during the interview that allowed the students to learn more about the learning object. Based on students' prior knowledge and the difficulties students might have with the learning object and the offer of learning, I try to get an answer to what might have contribut the students to developed knowledge of the learning object.

The objective of this thesis was to present a design proposal on a modular mechanicalstructure for a nanosatellite. The size of the structure should follow the CubeSatstandards. This standard divides satellites in units (U), where 1U is equivalent to acube where sides measure 100 mm. 2U corresponds to the same volume and size as2 assembled 1U structures, and so on. The focus was to develop a structure in theorder of 3U and 6U.At the integration in the satellite launch rocket, there are a couple of differentinterfaces, where the structure is adapted to common ones; P-POD and CSD.

This paper describes a case study of the largest film production ever conducted in Scandinavia. The study aims at explaining the complex relationships in the network structure in which the project took place. Coordination of creative projects carried out in a network context, includes handling conflicting interest and contradictions. Creativity needs space and freedom while projects need structure and coordination, whereby controlling these projects becomes complex. Adding to the complexity, does the loose form of organization that the network structure represents, without any long term structure.
