Undersökning av elektroniska scorekort på golfmarknaden : Var ligger problemet för fortsatt utveckling?
This is a Master´s Thesis based on my own idea instead of that of a company. It is a survey that focuses on finding out more about which part of the development process that is blocking the establishment of electronic scorecards on the golf market. Why has it not been introduced on the market in a larger scale yet, considering the technology we possess today? This question is investigated through interviews with the Swedish Golf association, and three companies that have chosen different paths to implement an electronic scorecard. The interviews focuses on finding out what developers and the association believe to be the main problem, before taking the next step in releasing electronic scorecards on a larger scale.

Skriftligt formkrav : det digitala dokumentet
This thesis seeks to investigate how an agreed written form requirement is met in an electronic environment. Swedish Contract law is applied since Sweden lack specific regulation for electronically closed agreements. Since contractual freedom prevails in Swedish law, it is up to the parties themselves to decide if the formal requirements to be applied.In order to assess whether the written requirement is fulfilled in the electronic environment, a purpose-oriented analysis should be made. When the purpose of why a written form requirement applies has been clarified, the analysis continues to assess whether the objective can be achieved with the modern form of communication. The method is called functional equivalence and means that when an electronic media fulfill the same functions as the paper medium so will the electronic medium as a starting point to give the same legal effect as if it were the case of a written paper document.
Lärande i molnet : EduSync belyst ur ett connectivistiskt synsätt
This essay has discussed and analyzed a draft for an idea about a network called EduSync. This idea is based on that teachers and students, attending and holding courses, all over the world should be able to find and interact with each other. EduSync is founded from a new learning theory, connectivism. Interviews, participation in a conference and two workshops have been used to gather information and different points of view concerning e-learning, for example possibilities and problems with this idea of a network. A comparison of web communities and e-learning environments that exists today was also done. The gathered information from persons as well as literature resulted in a discussion concerning learning and what would or would not be possible with the creation of EduSync.
Lärplattformar- verktyg för lärandet : Hur bör det utformas för att förbättra e-lärande för studenter på Linneuniversitet?
The development of the web has become an attractive area, with continuously and rapid development in the area it has led to a big change in the way of learning. Learning is a concept with many definitions, but a definition that is many at hand is that learning means that individuals seeking new knowledge and experiences that shape their goals, behavior and environment.With the development of the web a new way of learning emerged, E-learning. E-learning integrates information technology with the traditional learning to offers a flexible way of learning for students where they won't be dependent on time, place or others issues that would prevent their learning. E-learning takes shape of an application, LMS (Learning Management System). Today LMS are widely used in many universities, but with new technique comes new problems. The constant developments of the LMS have made the decision to use LMS difficult.

Vad skapar stress respektive trivsel hos avverkningslag? : en jämförelse mellan bolags- och entreprenörslag
As a student during my studies, I have been told about entrepreneurs who have red numbers in their financial statements, and there is a forest machine operator shortage in Sweden. The basic idea of this thesis was to examine the underlying factors that may have caused the problems described above.
The aim of this thesis was to investigate the factors that create stress and job satisfaction as a forest machine operator. The study was performed as a comparison between forest companies own harvesting teams and entrepreneur teams to investigate if there are any differences in stress and job satisfaction between the two different types of team. The study was conducted in collaboration with SCA Skog.
The material for this study was collected by doing interviews with SCA's harvesting teams. A total of 27 forest machine operators were interviewed, divided into a total of 10 separate harvesting teams.
It was very similar between the different type of teams, which situations the operators experienced stress.
Utveckling av HPLC-metoder för kvantifiering av nyckelkomponenter i en villkorad emulsion
Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.
Methods for Locating Distinct Features in Fingerprint Images
With the advance of the modern information society, the importance of reliable identity authentication has increased dramatically. Using biometrics as a means for verifying the identity of a person increases both the security and the convenience of the systems. By using yourself to verify your identity such risks as lost keys and misplaced passwords are removed and by virtue of this, convenience is also increased. The most mature and well-developed biometric technique is fingerprint recognition. Fingerprints are unique for each individual and they do not change over time, which is very desirable in this application.
?Barnen behöver de att erbjudas mer än bara en sandlåda med hinkar och spadar? : en undersökning kring förskolepedagogers uppfattningar om förskolegården och dess relation till barns lärande
The aim of this study is through a teacher perspective illustrate and analyze how preschool teachers apprehend children´s learning in relation to the preschool yard.The main research questions asked were:How do preschool teachers apprehend the preschool yard in reference to it as a place?In what way do preschool teachers use the preschool yard in their work with the children?How do preschool teachers view the preschool yard and the significance it has on children´s learning?The research is based on data collected through interviews and observations at four different preschools in the same municipality. The research views place and people as social constructions, a theory of knowledge that is based on the view that the world, places and people are constructed in relation to each other. This perspective as well as previous research is used for analyzing the data collected through a qualitive study based on interviews. The data analyzed show that the preschool teachers involved in this research apprehend the preschool yard as a central part in the learning of young children.
Internetbaserade distansutbildningar
In the informational age of today, continuous learning is of greatest importance. The demand for this seems to be increasing, while at the same time people are under more pressure to carry out more tasks in shorter amounts of time. A way to solve the problem of finding time to learn could be to make use of the possibilities that Internet offers for learning at a distance. The purpose of this thesis is to, from a pedagogical perspective, contribute to the discussion concerning Internet based distance education for a target population consisting of professionals. We have found that some of the courses included in the two certification programs which we have investigated are suitable for Internet based distance education.
Grupparbete - formella och informella samspelssituationer : en kvalitativ studie om sex elevers uppfattning kring lärande i grupparbete
The purpose of this study is to investigate what kind of idea a group of students in third grade, who attends a school in the Stockholm area, have on group work in school and how they think it affects their learning.The study is based on two questions:What opinion do the students have about group work?What opinion do the students have about how group work affects their learning?The method I have used to retrieve information has been to interview six different students, where the interviews were both individually and in groups. I started by interviewing students individually and then had a group interview. The idea with the group interview was to end it all with a brief discussion about the thoughts that came up during the individual interviews. I chose a selection of six students, four girls and two boys which they all were at the age of 9 and go to the same school.The socio-cultural and structural perspectives, is those theoretical perspectives that my study is based on.
?Seriously seeking comics? ? Ämnesbestämning, klassifikation och indexering av tecknade serier
The purpose of this master?s thesis is to examine how comics, here defined as a combination of text and images, are handled by the libraries in regards to subject analysis, classification and indexing. A comparative approach has been used in this study. First, common practices, methods and theories concerning subject analysis developed for documents consisting of text or images are presented. Then the current systems at two special libraries, specializing in comics and consequently dealing with both text and images, are examined and related to the above mentioned practices, in order to discover differences and similarities.
Universell kunskapsorganisation: identifiering av ett framväxande forskningsområde genom citeringsanalys.
An ongoing discussion concerning the possibilities of universal classification based on phenomena rather than on research disciplines has been noticed. In order to discover if this was a limited discussion or the beginning of a major new field of research a study of citations was made using the database Web of Science. In addition, references of the works concerned were studied to find out where the ideas originated. The study of references shows that the ideas originate in a limited number of older published works, some of them well established in Information Science, some of them less generally known. The main ideas commonly used in Information Science are Ranganathan?s facet theories and the work of the Classification Research Group.
