The application of performance-based pay system among enterprises is becoming more frequent. Performance-based pay systems is used by organizations in hope of increasing productivity and have become more flexible. Employees may perceive the performance-based salary as a motivator or a threat depending on lifesituation and personality. At a perceived threat, the employee may become stressed. Work-related stress has become a serious social problem that can have consequences for both companies and individuals.

We have performed a study much similar to Ritter?s (1991) about long-term aftermarket performance of IPOs on the Swedish market during the years 1990 to 2002. The study resulted in evidence for that Swedish IPO do underperforms their benchmark-portfolios during a 36-months period. Though, the grade of underperformance depends of the chosen benchmark. The study is mainly focused on a particular benchmark, a portfolio of non-issuing firms matched by size and sector.

To achieve peak performance as a young elite athlete, there are many psychological andphysical factors that have impact on human?s performance. Factors that affect theperformance interplay and interact must work to maintain ability to perform at its peak.The purpose of this study is to examine the factors that contribute to peak performance.Data collection method of the study has been done with a questionnaire, addressed toyoung elite athletes on a secondary school. It was 87 respondents who participated onvoluntary and anonymously conditions. The respondents consisted of men and womenbetween 16 and 19 years old.

The purpose of this study is to examine the difference between three query strategies with respect to retrieval effectiveness. The thesis aims at examining how two types of noun phrases containing a modifier to the head word, which is a noun affect the retrieval performance with regard to recall and precision. The noun phrases in the thesis are of two types: 1) noun phrases containing a modifier to the head word (which is a noun) and which are not dictionary phrases (NF) and 2) dictionary phrases. Both types of noun phrases in this thesis contain at least two words. The queries were executed in Query Performance Analyser, QPA, containing the InQuery system and a sub collection of TREC-Uta documents with its topics.

The purpose of this Masters thesis is to examine the performance of queries that are expanded by synonyms and hyponyms from Svenskt OrdNät, the Swedish version of the Princeton WordNet. Four different types of queries were constructed: a baseline query S1, the baseline query expanded with synonyms S2, the baseline query expanded with hyponyms S3 and finally the baseline query expanded with the synonyms and hyponyms used in S2 and S3. The terms for expansion were picked by hand. The queries were executed in the Query Performance Analyser QPA, a tool used in IR education and in experimental IR research for analysing and comparing the performance of individual queries. 20 topics from the test collection GP_HDINF were chosen for the experiment.

In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.

An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.

The aim of this study was to investigate whether there is a correlation between birth order, academic performance and need for achievement. 166 students from Alvesta Gymnasium/ High school and Växjö Fria Gymnasium/ High school participated in the study. The result showed a significant correlation between birth order and study result, but unlike previous studies this study showed that it was the youngest siblings that had the best academic performance. Furthermore, a significant correlation between academic performance and need for achievement was found, also that higher need for achievement results in higher academic performance. The study also showed that there is a significant correlation between birth order and need for achievement, and it is the youngest children that have the highest need for achievement.

This paper was part of the ongoing cooperation between the Swedish Civil Aviation Authority and the Department of Psychology at Lund University. The purpose of this study was to develop a self-report measure regarding human factors, for the air traffic controllers to fill out before they start their working shift. This in order to aid the team leaders in their judgment regarding the air traffic controller's ability to perform at the right safety level. The self-report measure would also serve as an aid for the air traffic controllers who have a responsibility regarding their own performance. If successful this self-report measure would make it easier for the air traffic controllers to be alert regarding certain factors that can have a large impact on their performance.

The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..

This masters thesis concerns a modeling project performed at Volvo Technology in Gothenburg, Sweden. The main purpose of the project has been to develop a physical model of the climate in construction vehicles that later on can be used in the development of an electronic climate controller. The focus of the work has been on one type of wheel loader and one type of excavator. The temperature inside the compartment has been set equal to the notion climate. With physical theories about air flow and heat transfer in respect, relations between the components in the climate unit and the compartment has been calculated.

A large amount of our time is spent indoors in an artificial climate. To make the experience pleasant there are requirements on the ventilation and the heating system. At the present time the most common form of heating is a radiator system complemented with a ventilation system. A ceiling heating system with combined heating and ventilation can replace the two separated systems. The benefit with a ceiling heating solution is that it saves space since the radiator system is no longer needed.

The thesis tries to answer how a combination of financial metrics and marketing metrics can improve strategic decision making. The purpose is to develop a strategic working method for general dealers. The method is based on the two theoretical frameworks "The strategic resource model" and "The importance-performance matrix". The suggested method is being tested in a small retail store environment on the Swedish market. The result of the test shows that a better suited strategy can be developed when this strategic method, which combines financial metrics with marketing metrics, is being used.

Humanity faces a major challenge with the climate and environmental crisis, largely driven by reckless recourse use and greenhouse gas emissions by corporations. The EU?s Corporate Sustainability Reporting Directive (CSRD) aims to standardise corporate sustainability reporting, making practices more transparent and comparable. This directive seeks to enhance sustainability practices and guide market forces towards sustainability, supporting the EU?s goal of net-zero emissions by 2050.
