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.
Barnkonventionens implementering i Lunds Kommun - en aktörsanalys
In 2002 the local council of Lund, Sweden, decides to implement the UN Convention of the Rights of the Child. A number of actors, such as the state, the civil society, the political society and the bureaucracy, participate in the political process with different authority and points of departure. This thesis studies the actors´ interactions from an inside perspective by applying concepts such as political power, democracy and implementation. The methodological departure is action research from within, a local NGO, the local board of Save the Children Sweden. The results of the study indicate that governance and steering of the implementation process at the communal level is weak.

Musik på Internet framtiden för bibliotekens musikavdelningar?
The purpose of this thesis is to discuss the possibilities of, and interest in, a digital download service at the music departments of the libraries. I chose to conduct my study at the city library of Gothenburg. I studied the legal download services that exist today and I did a statistical survey among the users of the music department, followed up by interviews to see how they took to the idea. From the inquiry I learned that a majority of the users was negative to having a digital service replacing the physical department, although a majority was positive to try a digital service. I also used the inquiry to compare the reasons for downloading music to the reasons for borrowing records from the library, but there was no significant difference.
KOLLEKTIVTRAFIKENS GEOGRAFISKA VARIATIONER I TID OCH KOSTNAD ? HUR PÅVERKAR DETTA BOSTADSPRISERNA? : Fallstudie Uppsala län med pendlingsomland
The distance between home and work has increased in recent decades. By the development of infrastructure and public transport, jobs farther from home have become more accessible and this development has in turn increased commuting. Commuting travellers often pass over administrative boundaries which often serve as borders for public transport pricing. Also the market control prices. Research shows that travel times and costs significantly affect commuting choice.
Nyckeln till visning - En kvantitativ studie av att sälja och bli såld på detaljbilder
Previous research in the field of consumer marketing has confirmed the positive effects of divergence on advertising efficiency. Despite the coherent evidence, some industries lag in the adoption of these findings, one of which is the Swedish real estate market. Divergence has not been elaborately investigated within said context and this paper addresses the need of actionable insights for housing advertising. Starting with the proven success of housing firm Fantastic Frank who work with detail photos in contrast to the common wide angle, this paper examines theoretical implications of detail photos' characteristics. Besides being divergent, detail photos are also ambiguous which renders access to effects related to visual perception.
Användning av geografiskt informationssystem (GIS) vid studier av nötkreatur i landskapet - en pilotstudie :
The Animal Protection Agency was in 2006, commissioned by the Government to: Evaluate how free range animals in the winter, can be kept and managed with special emphasis to animal welfare. The Animal Protection Agency was closed later in 2006 and the commission moved to the Swedish Board of Agriculture. The keeping of free range out wintered cattle, certain basic requirement are needed: by regulation, cattle should have access to a lying hall or other building that gives protection against aversive weather and wind and should offer a dry and clean lying area. There is a possibility for farmers that get an exemption from this regulation. But cases regarding farms which have had difficulties for this exemption has led to a discussion about if the animals can get the same protection in the nature which is comparable to a lying- hall.
Jätteuttrar och deras beteende när de tilldelas musslor i hägn
The giant otter (Pteronura brasiliensis) is listed as an endangered species and scientific litterature concerning its biology and behaviour is scarce. The current study observed a group of three giant otters in a Swedish zoo. First the otters normal behaviour was recorded. Then the aim of the study was to see if the otters behaviour changed when given blue mussels (Mytilus edulis). Furthermore the aim was to see if the otters displayed any tool-using behaviour when given mussels.
GeoAnalys i Flashmiljö
There exists a great need among companies and other organizations to be able to visualize statistics. It?s also increasingly common to ask for web-based solutions for increased flexibility and accessibility for users. This paper describes how large amounts of geovisual data, for a large number of regions, can be visualized in an interactive and well-presented manner. The paper let?s you walk through two application scenarios, developed in a Flash environment, using the GeoViz component library for visualization. The first application has been developed for Statistics Sweden (SCB), to give a solution on how to visualize statistics for Sweden?s zip code regions.
Med datorn som följeslagare : Perspektiv på datorers inverkan för lärare i ett En-till-En-projekt
In today?s society we depend on technology to perform the simplest tasks. Whether we are engaging in conversation with a friend or are navigating in traffic, we are likely to be found with some technological device in our hands. This dependence has grown over a period of time, and many of us have failed to reflect on the impact technology has had on our lives. The emergence of so-called One-to-One projects, where teachers and students gain access to a personal laptop, does however provide an excellent opportunity to do so.
Förbättrar en kvalitetssäkring skördarens dimensionsmätning?
In this study it was investigated if the adoption of a new routine for quality control could improve the precision of the dimension measurement obtained by harvesters. Data was collected from three different harvesters. First, a reference data set was collected before the new procedures had been incorporated, and then when the new methodology was implemented another data set was collected by the harvester operators, allowing the two data set to be compered.
The results indicated that following the implementation of the new procedures, the reliability and the precision of the measurements has increased. All harvesters included in the study had improved regarding most of the controlled factors such as standard deviation, systematic difference and hit rate within ± 2 cm for length and ± 4 mm for diameter..

Etik och censur inom internetfiltrering ? En forskningsöversikt
This paper is a research review in the realm of censorship systems andfiltering systems. It applies ethical considerations to the creation of censorshipsystems bringing forward discussion on the ethics of technology with thepurpose of limiting access to information.There is active research being done in the area of automatic content filteringand censorship systems. These are systems that can filter out undesiredmaterial, typically from the Internet, automatically. Used in some nations,many schools and even mandated in some libraries there are many ethicalquestions raised concerning censorship and access to information.Part of the review concerns the level of accuracy of these systems presentedby researchers in the field and the different approaches used. Reviewedarticles centre around automatic content classification and filtering ofpotentially harmful materials with regards to minors while some relate tocensorship technology in a wider sense.Results show a general lack of discussion concerning the ethics of thetechnology in the research reviewed.
Indexering av humanistisk litteratur och humanistiska databaser ? exemplet MLA International Bibliography
This thesis aims to answer the following questions: What type of vocabulary is used in the humanities? What does this implicate when it comes to indexing in the humanities? How do humanities scholars seek information and what type of information do they need? What consequences does this have when it comes to the development of humanities databases? How is the MLA International Bibliography organized? How does its indexing system ? CIFT ? work? How does the MLA International Bibliography correspond with the needs of the humanities scholar? The study shows that the type of vocabulary used in the humanities differs significantly from that used in the sciences. Therefore, information retrieval is often said to be problematic in the humanities when compared to the sciences. This is, however, not completely true. If consideration is taken to the different type of vocabulary used in the humanities, subject access proves to be more straightforward than has been generally recognized.
