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 amount of various phosphorus (P) fractions in the sediment and the relationship between the amount of P and sediment particle size were investigated in a constructed wetland southwest of Linköping. Furthermore, the possible correlation between clay content in the sediment and distance from the inlet was investigated. Sediment samples were collected along three transects from the inlet to the outlet, with six samples in each transect. In order to measure the soluble P, an NH4Cl extraction was done. This was also analysed for total soluble P after oxidation with peroxodisulphate.

She calls them, general education, alternative and demand.

Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

The purpose of this study is to illustrate teacher humor by critically examining it from an interpersonal- and humor communicative-perspective; and to discuss teacher interpersonal humor communication-skills in relation to the Swedish high school curriculum, collegial relationships and pedagogical aspects. The study?s empiric material consists of semi-structured interviews with six high school-teachers currently working at the same school, but of different age and gender. The interviews indicate that the informants all have developed humor competence, an interpersonal communicative-skill that allows them to use humor efficiently. Moreover, the result demonstrates that the teachers have various humor approaches but that they all use humor in the classroom for much of the same reasons.

Researchers claim that stress has become a word of fashion and is now frequently used. They also state that there is no accepted definition that can easily describe the concept. In this essay, I have examined children and stress. The aim of the diploma work is to illustrate stress more closely the stress concept, the underlying reasons that can influence children and how teachers and school staff support children in their stress handling. My three issues are: What is stress? What stressors put children, at home and at school, in a stress situation? How can teachers help children to manage their stress? The diploma work is based on a literature study in order to find out what has been written on the subject in earlier research.

The question how teaching should be organized in order to give the students the help and support they need to reach their goals is always of vital interest. All students are unique individuals with different prerequisities, possibilities and needs. Streaming in mathematics could be one solution.The first week at upper secondary school a diagnostic test is carried through. Thereafter, the result is used as a basis for dividing the classes into different teaching groups. Thus, the groups working with mathematics become more homogeneous and the students? previous knowledge is approximately at the same level.

The purpose of this master`s thesis is to examine how the contemporary changes in society display itself in the network Ecumenical Forum of European Christian Women EFECW and to increase the understanding of networks. My main questions are: What does the networks structure look like? What does the networks relationships look like? How is identity created in the network and what types of identities is created? The objectives are reached by using two methods, qualitative inquiries and document analysis. The inquiries were carried out to nine members in the network of different countries. The theoretical framework of the thesis is Manuel Castells theories of the network society, and the study is also placed in context by a presentation of previous research on the field.

The purpose of the study is to explore the internal implementation and communication of ecological sustainability within an organization and to identify obstacles and challenges that may arise. To address the study's purpose and research questions, a qualitative methodology and semi-structured interviews were used. Respondents were selected from two different units within a large global organization operating in the automotive industry. The study's findings indicate that the organization's sustainability efforts are extensive and integrated across several departments. It is also evident that sustainability initiatives are primarily driven by upper management within the organization, although there is room for lower hierarchical levels to provide some feedback.

The aging population is a challenge for Europe and there must be cooperation between EU member states to join the challenge to meet. The purpose of this study is to describe and analyze the EU's ability to influence older people's health, based on experiences from a selection of European officials and on a review of the EU's common strategies. The authors studied and problematize the implementation of the strategies that the EU has negotiated for the work against the elderly poor health, with a view of member countries have different conditions. Using qualitative methods, we have collected and processed statements from targeted interviews and publications by a range of European policies. The material was then analyzed from implementation theory and organizational theory, and based on results of previous research. The result shows that the EU is developing common strategies and coordination methods to the aforementioned challenge to meet. The results also show that the differences existing between Member States causes implementation difficulties of the common strategies. The study states ultimately decide that there should be common strategies to facilitate the work of Member States when it comes to countering the elderly poor health.

Målet med detta examensarbete, utfört på uppdrag av Vectura Consulting AB, har varit att undersöka möjligheten att ansluta en vindkraftpark till järnvägens kontaktledningsnät. Möjligheten att koppla om vindkraftparken till järnvägens hjälpkraftnät, som bland annat förser växelvärmare och signalsystem med effekt, har också undersökts. Eftersom kontaktledningsnätet och hjälpkraftnätet arbetar med olika frekvenser och spänningar, 16? Hz och 15 kV respektive 50 Hz och 22 kV, måste därför en komplett krets för frekvensomvandling, spänningsomvandling och omkoppling tas fram. Projektet har begränsats till en del av Botniabanan, sträckan Örnsköldsvik-Nordmaling.I denna rapport har trafikfrekvensen på den valda sträckan på Botniabanan undersökts för att bestämma en genererad effekt till inkopplingspunkten, samt för att undersöka när det kan vara lämpligt att koppla om till hjälpkraftnätet.

Coordinator of public health has recently become a new profession in the field of Health Promotion. During the last few years the pedagogic perspective has been increasingly important for the coordinators as a way of adapting their work methods to the circumstances. The conditions for coordinators of public health differ between municipalities and thus their tasks and responsibilities may vary with the local structure. According to the literature there are several ways to conduct Health Promotion and it is in the hands of the coordinator to adjust the methods to fit local conditions. The purpose of the study was to examine what influences the coordinators of public health and how that affects their work methods.

Unhealthiness is not just a damaged back or asbestos. The fact that mental ill-health seems to increase in our society is well known. Statistics from Arbetsmiljöverket proves a fourfold increase of work-related disorders since 1997.
