Platt Hierarki : Metoder för omvandling av relationsdata till hierarkisk data

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.

Platt och jämlikt? : En fallstudie av Feministiskt Initiativ

The aim of this work is to define the party structure of Feministic Initiative (FI). We want to examine the structure of an organization that doesn?t start out with a hierarchical order. We further intend to examine the party?s leadership; whether or not it is equal, between the three spokespersons.We find it interesting as a topic from a democratic point of view as well as to see if a flat structure could work in practice.

Organisering av ojämställdhet - En studie av kvinnors möjligheter att nå chefspositioner i Försvarsmaktens personalstab

This thesis aims to examine why women are prevented from attaining high positions in organizations. By executing a case study through qualitative interviews with employees from the Human Resource Department at the agency for Swedish Armed Forces, this study presents eight general and specific explanatory factors that hinder women from making a vertical career. The general factors include that women are discriminated against, women are perceived as less competent, men have created organizations and it is easier to recruit men. The specific factors include that a hierarchical organizational structure is correlated to inequality, that both the agency for Swedish Armed Forces and leadership are associated with masculinity and that women with civil competence face double misfortune. The division between general and specific factors indicate that the explanatory factors vary between organizations, which among other things implies that equality work should be tailored for the specific organization.

En korrelationell studie om beröringsundvikande, hierarkier och kränkning bland intagna vid en sluten kriminalvårdsanstalt

The aim of this investigation was to assess if there was a correlation between touch avoidance and hierarchical position, perceived degradation, number of years spent in jail and age amongst men at a correctional institution. In addition, a possible correlation between hierarchical position and the amount of perceived degrading treatment was also explored. In the collection of the data a questionnaire containing 27 open and closed answer alternatives was utilized. A multiple regressional analysis was conducted to find possible correlations between touch avoidance and the other underlying variables. Also an independent t-test explored the possible effects of the control variables: place of birth and girlfriend.

Artificiell intelligens : Prestanda hos beteendeträd och Hierarchical Task Network

Detta arbete undersöker skillnader i tidseffektivitet mellan beteendeträd ochHierarchical Task Network. En enklare spelprototyp av typen top-down 2D shoot-emup implementerades. Spelprototypen använder två typer av autonom motspelare så kallade botar. En bot för beteendeträd och en bot för Hierarchical Task Network. Spelprototypen mäter körtiden för varje typ av bot i sex olika situationer.

Target Capital Structure and Adjustment Speed- a dynamic panel data analysis of Swedish firms

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.

Den organisatoriska strukturens påverkan på Agile i praktiken

Agile as an idea was created in 2001 through the Agile Manifesto with focus on social relationships, communication and flexibility. This was a reaction to the traditional, hierarchical organization with the goal of restoring balance within organizations in the IT business. Today we can see a transit of Agile from the IT-industry to other industries and areas, such as HRM.There is a challenge in attempting to traditionally control a social idea such as Agile, and there is a lack of empirical studies of the organizational context and its effect on the interpretation of Agile in practice. This study is an attempt to connect Agile to the science of business administration.The purpose with this study is therefore to research the organizational contexts effects on the interpretation of Agile in practice, within IT and HRM. Where Agile is established or well known.To fulfill our purpose we chose social constructivism as our scientifically approach, and conducted 12 in-depth interviews.

The Capital Structure Puzzle of SME's - Evidence from the Swedish Security Industry

The purpose of this thesis is to ascertain the main determinable factors of Swedish SMEs capital structure decisions and to investigate whether existing capital structure theories are applicable on Swedish SME financing. We have used panel data to run regressions of various capital structure determinants on three measures of capital structure; short- term debt, long-term debt and total debt. We found that growth opportunities, profitability and age are the most important capitalstructures determinants for our sample. Firm size shows a small explanatory result but the effective tax rate and the asset tangibility do not seem to explain the capital structure at all. Thematurity matching principle is considered significant..

Migration of a very large database with Swedish demographic data, using Microsoft SQL Server

SMC is in the process of developing a micro simulation model. The existing micro simulation model developed at Cornell University for US data, CorSim, is one of the fundamental parts for the new micro simulation at SMC. To develop the Swedish model, Swedish data on all individuals in Sweden during 11 years are also available. These data are organized in a database. This paper describes the process of rebuilding the database to a more useful structure.

Swedish SME Financing - Evidence from the Game Industry

The objective of this thesis is to examine the capital structure of Swedish small and medium sized enterprises (SMEs). Accounting data from Swedish game developers, combined with the result from a survey, is used to examine their financial conditions and capital structure decisions. We find that non-debt tax shield, firm size, growth opportunities and age are, to various extents, the determinants of capital structure in the game industry, while effective tax rate and asset structure have marginal effects. Our study also implicates that most of the existing capital structure theories can explain SMEs leverage decisions to some extent; however, some adaptation is needed to fit these theories into the SME context. Additionally, we find the existence of a financial gap in the game industry which might need efforts from both demand side and supply side to eliminate..

Informationssökning i tre olika hypertextstrukturer - ett experiment

The aim of this study was to find out if hypertext structure has any relevance for the efficiency of information retrieval. An experiment, in which three variants of hypertext structure were compared, was carried out in the autumn of 1998. Three websites with different structures were constructed for this purpose: a sequential version, a hierarchical version and a webcluster version. 44 subjects, all students at the University of Lund, were randomly divided into three groups. Subjects were requiered to answer a number of questions using one of the three versions.

"Att bygga broar över murar" : en studie av ett kvinnligt ekumeniskt nätverk

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.

SAB-systemet och Yahoo! En jämförelse rörande traditionell och ny klassifikation

The aim of this Master thesis is to investigate the similarities and differences between a traditional and a new classification scheme. Two classification systems are compared, "The Swedish Library Classification System" the SAB-system - and Yahoo!. The SAB-system has been used in Swedish libraries since the beginning of the 20^th century, and Yahoo! has been online since 1994. Yahoo! has a Swedish version of its international original, which is used in this study to get a similar starting point with the SAB-system. The method used for this is a content analysis, which in this case is not a quantitative analysis.

Kvinnan:mannen::alternativet:normen ett feministiskt perspektiv på klassifikation

Using a feministic perspective and a critical approach, my purpose is to discuss bibliographic classification, a central aspect of Library and Information Science. More specifically, my aim is to demonstrate the norms and the dominating thoughts regarding the organization and representation of knowledge, subjects, and social categories in classification systems. I review previous research involving critical approaches to classification. These show that classification systems are a reflection of the context in which they are created, with the result that universal assumptions can be questioned. Some studies also present problems inherent in hierarchical structures.

4 organisationer och 825 chefer : En studie om chefslösa organisationer

This Bachelor?s thesis is about bossless organizations. We have observed that the hierarchical structure that the majority of organizations is structured by today is a remnant of a time long gone, and can be an obstacle for independent thinking and responsibility inside organizations. We want to question the accepted perception that an organization is best structured in a hierarchic form.The purpose of the thesis is to provide an understanding of how a bossless organization works and to give a concrete explanation of the consequences of this kind of organizational structure.The thesis is of a qualitative nature and is designed with an inductive approach at an organizational level. We conducted a case study on a bossless company and supplemented this with secondary sources from three other bossless organizations.It concludes that the bossless approach can work and that there are a number of advantages to benefit from it.
