Aims The aim of this study was to investigate how personnel within food control are regarded from different perspectives and to find the answers to the sub questions:- what is included in the profession of food control?- what are the requirements for personnel within the profession of food control?- how is the profession perceived from different perspectives?- how do personnel within the profession of food control estimate their psycho social working conditions?Method The study included 68 individuals (34 female and 34 male) and was conducted via observations, web-based surveys and survey-based interviews. Conclusion - The study was feasible.- The overall goal of the study as well as the research questions were answered to and contributed to clarify what is included in the profession of food control. - Quality measures should be implemented to greater extent within the development of the national food control system..

Technology evolves quickly, with innovative ideas growing everywhere. Still, no technology is anywhere near challenging the mouse and keyboard for navigation of your standard computer. This study focuses on comparing the traditional technologies of mouse and keyboard with the new technology of gestures - in this case Leap Motion - in purpose of finding how the usage differs and what the potential users want from the competing technology. The experiment was executed in a controlled environment, with as few external factors as possible. We found that although the test subjects found Leap Motion fun, the test subjects do not want to surf the web with gestures.

This paper discusses the advantages and disadvantages of using different benchmarking models to measure and compare the efficiency of Swedish gas distributors. It also discusses to which extent the results of a benchmarking study should influence the revenue-cap which will be implemented in the gas distribution sector in Sweden from year 2011. The discussion is based on arguments from both theory and practical applications of benchmarking. The results suggest that benchmarking Swedish gas distributors against distributors in another country using a parametric model is most favorable, but the reliability will be increased if non-parametric models are used also. Partial and total productivity measures could be used to confirm results of other benchmarking analyses.

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.

There are a huge number of books and articles written in the field of usability and about the art of giving the user the opportunity to find the information he is trying to reach while browsing the website. The writers of these books are handling guidelines that are recommended to be followed, as well as describing their own views, ideas and theories of the subject. We found an interest to research the different possibilities, if any, to develop a website optimal for the user from a usability point of view. Another thing we noticed was that a need of a substantial guidance existed in website development aimed for recently started companies.New theories and rules regarding usability, which are seen as superior to the old ones and therefore replaces them, is not created that often. This is different from other IT related subjects.

The term ?social competence? is widely used by organizations in job advertisements, despite the problems of making a unified definition of it. The purpose of this study is to investigate which features the organizations require, why organizations require them and how the assessment is implemented for recruitment. To answer the purpose of this study, eight qualitative interviews conducted with recruiters from four different staffing agencies. Further a literature study was performed to define the concept of ?social competence? and its meaning, in order to later connect this to the result.

The aim of this thesis was twofold, on the one hand to compile a set of usability and accessibility guidelines in order to establish the characteristics of a user friendly website, and on the other to test these guidelines on eight library webcourses with user education to see how well they adhered to the guidelines. The methods used were literature survey and source studies. The guidelines found in the literature survey were divided into four different categories: document properties, structure and navigability, visual characteristics and accessibility. In order to establish the adequacy of the guidelines, I examined reference sources, mostly on the web. To a certain extent this examination has been based on HCI Human-Computer interaction theories.

The purpose with this study was to find out about the preschool toddler?s peer-cultures. I also wanted to understand how these peer-cultures were shown.My questions are as following:What is it that the children interpretive and reproduce in their play?How do children gain access to play?How do children exclude each other?What position of status can be seen in children´s play?I used observations as the method to find the answer to these questions. These observations where implemented during five occasions at two different preschools.

This thesis aims to investigate if there are any differences in the value relevance of yearly earnings announcements before (2000-2004) and after (2005-2009) IFRS were implemented for listed companies in the European Union. To assess the value relevance of earnings, an earnings response coefficient (ERC) is estimated using a linear OLS-regression model. The regression model uses accounting earnings per share as the explaining variable, with the corresponding return starting from (but not including) the previous year's earnings announcement date, ending at (and including) the current earnings announcement date, as the dependent variable. This study finds that there is no statistically significant difference between the estimated ERCs for the two periods. Although no statistically significant difference is found, data shows that the R2-values, which measure the explanatory power of the regressions, are higher for the period before IFRS.

Firewalls protect network traffic and decide witch traffic to send further and witch traffic will be blocked. All this depends on the rules in the firewall. The firewall is installed between the internal network and the Internet. It is difficult to find a firewall that can protect us against different threats. Firewalls have both advantages and disadvantages and all this make them vulnerable.

Studien grundar sig i ett intresse för hur barn interagerar med datorspel. Datorer och datorspel blir mer och mer vanliga i barnens omvärld. Syftet med studien är att belysa och beskriva hur barn i fem års åldern gör när de spelar ett datorspel och hur de interagerar med det. Vi belyser bland annat hur barnen tolkar ikoner, hur de förstår den auditiva informationen i kombination med bilderna, och vilka strategier de använder för att ta sig vidare i spelet. Vi studerar också vad de minns när de spelar spelet för andra gången.

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.

In our modern society, time is important. Technology is used in countless ways to faster get us from one point to another. The purpose of this report is to inquire whether there is a way to implement an option for personnel at Swedish hospitals to claim priority on an elevator call, and to do this in an efficient way. An ordinary elevator system has been simulated with an implementation of textit{Nearest Car algorithm}, an algorithm which calculates the most suitable elevator car to serve a specific call considering the distance between the call floor and the car and the direction. Along with this algorithm, different ways to handle priority calls has been implemented to see how they affect the mean transport time for both passengers with priority and regular passengers in the elevator.

This study focuses on how the idea of sustainability is dealt with by companies, how the idea changes when moving through a company structure and how the different individuals interpret the idea. To date, many different studies have been written on the subject of sustainability, but few share the perspective addressed in this particular study. This case study was formed at a paper mill in the central part of Sweden. Semi-structured interviews with employees working on different hierarchical levels, within the same company, were chosen in order to get an insight into how the idea of sustainability is implemented throughout an entire company. The interviews have been transcribed to help identify contrasting patterns.This study has shown that the idea of sustainability, and its context within society, differs from how the idea is perceived in the organization.

The purpose of my study is to examine why five primary school teachers chose to start using the method ?Learning reading by writing on computer? in their teaching. How do they perceive that the method works in their classroom and do they perceive that the method affect the children?s literacy?The study consists of a qualitative method in form of interviews with five primary school teachers and also some observations made by me in the classrooms. I will use the findings I made during the interviews and observations and contrast these to relevant literature and research that I have collected.The result of my study shows that all of the interviewed teachers had a self-interest in working with the method ?Learning reading by writing on computers? and that they also worked closely with colleagues.
