Riskkapitalbolags inverkan på risk för finansiell kris i portföljbolag: En studie av 53 transaktioner i tillverkningsindustrin
The aim of this small thesis is to investigate if the probability of business failure is higher at the time of divestment than at the time of acquisition for portfolio companies that have been subject to private equity ownership. The background for this thesis is the widespread critique aimed at private equity firms, claiming that they increase the risk in their portfolio companies. We have performed a study of 53 buyout transactions, involving Swedish manufacturing companies, covering a time span of 13 years, from 1995 to 2007. We find evidence of an increased risk of business failure for the portfolio companies with a short forecasting horizon (within one year). The absolute increase in the sample is however small.
Får jag använda lärplattan? : En studie i förskolans verksamhet
The purpose of this study is to highlight some aspects of the increased usage of tablets in preschool environments by answering the questions: what does the tablet become in the preschool environment, how much freedom does the children have over its usage.To answer these questions a series of observations were made at two different preschools. The observations were then complemented by interviews with teachers at the same preschools.This qualitative study focuses on some of the didactic questions regarding the tablets, based on a theoretical framework that is within the design-oriented perspective; which addresses the children's? autonomy, the institutional framework and affordance.Our conclusion is that the tablet?s introduction in the preschool has helped the teachers in numerous parts of their documentation, but we can also see that the children's opportunities to make choices regarding the tablet are more limited than with any other resource on the preschool. In our results we also see that when the children get access to the tablet they receive a learning experience, which among other things, strengthens their language skills and their social interaction with each other..
Evaluation of lithium-heparintube analyses performance
Today, some kind of laboratory results is required for around 70% of the diagnostics and follow-ups for diseases. In many of the cases the time from sampling to a result is very critical. Therefore the discussion of how to improve this situation has begun. For many analyses serum has been the routine choice for a long time but now it is disputed. After blood collection in a serum tube it is essential to wait 30-60 minutes before centrifugation and analysis of the sample, a long time for someone in an acute state.

Konstruktion av spoltorn för höj- och sänkbar överkorg till diskmaskin
Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.
Kartläggning av preoperativa fasterutiner på tre vårdavdelningar
The aim of this study was to investigate for how long patients fast before thoracic surgery, plastic surgery and ear, nose and throat surgery, at the University hospital of Uppsala, and what knowledge patients have about fasting and how they get affected by it. 30 patients were interviewed, 10 patients at each ward, according to a questionnaire. Data processing was performed with SPSS. There was no difference in fasting time for solids between the wards but the mean fasting time was 14 hours. In the thoracic ward patients fasted from liquids considerably longer than in the other wards.
Populärkultur på fritidshemmet : Hur påverkar populärkulturen innehållet i verksamheten?
This work is about popular culture in leisure. Teachers at leisure, on the basis of Education's governing documents working with developing an activity for students when applying the students' own interests. Although these councils are posted, several teachers around the country rejects certain activities or products that the students want to do or play with during their free time at the leisure time. Therefore the purpose of this study is to try to understand what teachers in leisure attitude to popular culture is and if they integrate the popular culture in there activities. To understand this, a qualitative study of interviewed teachers in various leisure was used.

Identifikation av produktionsstörningar och obalanser vid tillverkning av golvskenor
Our report procedure identification of instability and disturbance in an automatic manufacturing line of processing and assembling of chair sliding rails at Sapas manufacturing department in Vetlanda.To obtain a stabile ground we have mapped the material flow to receive a comprehensive view and to visualise connections.We have examined cycle times at different stations in purpose to identificate bottlenecks. The result of our examination showed that the bottleneck of the line was the brush station. This leads to that the expected bottlenecks identificated by Sapa gets a delay time and by that a longer cycle time.Interruptions has a clear negative influence at the line performance so we have also assemble data through the operators report list and compiled these in order to find out the interruptions effect on the line. The outcome during our assembled period was that the reported interruptions corresponded about 30 percent of the total available production time. This has a clear negative effect on the line productivity and efficiency as we have calculated in order to get the present status..
MÖJLIGHETERNA MED CLUSTERED COLUMNSTORE INDEXES & IN-MEMORY OLTP
Clustered Columnstore Indexes (CCI) and In-Memory Online Transaction Processing (OLTP) are two new techniques that were introduced with Microsoft?s new database management system SQL Server 2014.The thesis analyzes these two techniques, describes the theory behind them and also the background information that needs to be known to understand more of the new techniques. Performance tests of the new techniques have been performed to see how much faster response time we can get and less storage we need to use where the result is represented by performance diagrams and a compression diagram. This thesis is a cooperative work with a company called Trimma and the result is used as support to decide if these new techniques could be of advantage for the company.The test consists of five test queries with different purposes. The result is illustrated by diagrams that show the result and another diagram that shows how much the data gets compressed with the different techniques.
?Jävla Muminfitta? : Verbala förolämpningar och 34 andra humortyper isvenska komediserier på TV
Humor is as interesting as it is hard to define. It has travelled a long way since Hippokratestheory about body fluids and how someone, if lacking one of these, were called a humorist andwere laughed at.In this thesis we developed a new method for categorizing types of humor in Swedish comedyseries on TV. We chose six different shows (Grotesco, KvarteretSkatan, Morgonsoffan, Fredaghelaveckan, Parlamentet and Hjälp!) from the two most popular TV-channels in Sweden(SVT1 & TV4).We based or method on previous researchers? work and came to find some categories that wererepresented in most of the previous work. Our own method came to contain seven categorieswhich we believe is enough to obtain all kinds of humor in Swedish comedy series on TV.In our study we saw that most of the humor fell under the category that we called unnormalityhumor,a category which contained incongruity which many researchers believe is afundamental part of humor.Our opinion is that the unnormality-category became too wide in our study and that we perhapsshould have divided it into two or possibly three categories to see a more distinctive result.Nonetheless, our result offers an interesting starting point for future comparative studiesfocusing on similar subjects..
Good cop - bad cop? : - en jämförelse i ilska och aggression hos polisstudenter och universitetsstudenter
The main purpose of this study was to compare the levels of anger and aggression between male and female Police Academy students (N=106) and male university students (N=100), using 2 psychometric anger instruments; Novaco Anger Scale-1998-S (NAS-1998-S) and Aggression Questionnaire-S (AQ-S). Another aim was to examine if there was a difference in anger and aggression between male and female Police Academy students. Questionnaires were handed out to Police Academy students in Växjö and the result was compared to university students from a previous study by Lindqvist, Dåderman & Hellström (2003). Analyses using a series of Independent sample t-tests showed a significantly lower level of anger and aggression in the Police Academy sample. There were no significant difference in anger and aggression between males and females with the exception of two subscales of the NAS-1998-S and AQ-S; females scored significantly higher on NAS Arousal and males scored significantly higher on AQ Physical aggression..
