Barren rearing environment and early weaning of piglets can lead to a high level of distress, behavioural disturbances and reduction in weight gain. The main aim of this thesis was to study the effects of potential enrichment objects on piglet?s behaviour and weight gain during the pre- and post-weaning period. The second aim was to examine what type of object stimulated the highest frequency of interaction. The study was carried out at the Swedish Livestock Research Centre in Lövsta where a batch of litters from 10 first-parity Yorkshire sows were used.

This essay aims to examine managers experiences of control at the workplace within the property sector, and how these experiences differ between female and male managers. This study is a qualitative single case study that intends to offer a deeper understanding of a unique case and uses an abductive method approach. The essay is based on two main theories, Foucault?s (2003) theory of control and the gender system of Hirdman (1988, 2001) and is supplemented by previous studies of the modern workplace. The study is based on eighteen semi-structured interviews that aims to capture the participants personal experiences regarding control at the modern workplace, and the norms, surveillance, hierarchies, and self-discipline that make up this control.

The Effects of dietary biotin supplementation on hoof health in Swedish dairy cows - a controlled cohort field study. The aim of the present degree project was to investigate the effects of biotin supplementation on hoof health in dairy cows. The experiment was performed as a controlled cohort study in three commercial farms in western Sweden from January 2002 to October 2002. The cows were all housed in cubicle systems with transponder concentrate feeding systems. Within each farm the cows were allocated to either biotin or control treatment. The biotin groups received 20 mg of biotin per cow and day, starting 14 days before expected calving.

The accounting scandals that have attracted attention in recent years have led to internal control becoming a more central part of business activity. Doubts about what firms actually do have increased, all caused by the attention of accounting scandals. To counter this, frameworks and laws evolved and gained a significant role in the organization and its surroundings. The aim of the present study is to find out how four companies in the Kristianstad region are working to ensure its internal control and how they work to minimize risk and reduce uncertainty. We have used a qualitative method and interviewed a person in a senior position in each company.

The study examined what NHL-teams should improve. This has been done by studying the significant statistics of NHL-seasons, and with linear regression identifying what NHL-teams should do to win many points and thereby get a good placement in the final table. The most interesting result of the study is that the statistics on faceoffs and shots on goal and power play efficiency most seasons where irrelevant for the outcome of a season..

The purpose of this study was to describe perceived psychosocial work environment and musculoskeletal complaints among baggage handlers, and to evaluate whether there is any linear relationship between them. The study is a questionnaire based cross-sectional study, and part of an ongoing larger project. Therefore, the number of forms has been limited to those that were collected in the project by 2010-11-25 (N=117). The questions analyzed in the study come from the Copenhagen Psychosocial Questionnaire and ?Nordiska Ministerrådets formulär om besvär i rörelseorganen?, respectively.

Management control systems are a popular area of research and a lot of new research has been done over the past years. This development has been looking into new situations and circumstances, and interdisciplinary studies are being made to further understand the connection between different fields of study. A new field of study that has grown significantly over the past few years is the connection between management control systems and entrepreneurship. Leading researchers have proposed a number of questions for further research and one of them is the board of directors? use of management control systems in entrepreneurial firms.The purpose of this study was to examine the differences and similarities in the board of directors? use of management control systems between entrepreneurial and non-entrepreneurial firms.The study was conducted as a deductive qualitative study through interviews with respondents from entrepreneurial and non-entrepreneurial firms.

Forest management contributes to the changes in forest structure by turning heterogenous forests of varied age into homogenous forests of similar age and thus affect bird species depending on different structures or habitats which are lost during forestry. In this report, a study was made to investigate how the amount of decidious trees, dead wood and variation in tree diameter affect bird diversity. The purpose of this study was to be able to give forest management guidelines to increase bird diversity. This study was conducted by investigating 65 transects in forests of different structure south of Linköping, Sweden. Along the 65 transects, birds were inventoried as well as the vegetation.

This master thesis has been carried out at Scania R&D at the department of Powertrain Control System Development during the winter 2011/2012. The purpose of the thesis was to produce a method that with the result of troubles codes from the field testing would be able to say something about the maturation of a component, in this case the VGT, variable geometry turbocharger. To start with, it was necessary to investigate hich information was available. After the information been summed up in tables and charts, this so that it was possible to understand the huge amount of data, the calculations started.Since the thesis was about maturation of a component the proportions were calculated of components that had a trouble code in contrast of those who passed the test without a trouble code. This Thesis includes background information about basic of statistics and about the company Scania and its testing process.

This thesis studies the negative impact that control signal saturation may have on a controlled system. Different methods that are used to compensate for this problem are also studied and evaluated. Both sensitivity to disturbances and the effect the method has on the systems'ability to follow a reference signal will be examined. Stability will be discussed, but no conclusions whether the systems are stabilized or not can be drawn. Control signal saturation will lead to a slower behavior in general.

Transfer pricing including internal loans have increased in recent years, making it easier for companies to minimize their taxable income. After the Swedish court case Diligentia, there have been discussions regarding the influence of a parent company's transparency and control of the subsidiary with regards to the interest rates on internal loans. In court cases that followed Diligentia, the Swedish Tax Agency argued that a parent company always could be assumed to have sufficient transparency and control of the operations in the subsidiary, and therefore reduce the risk on their debt obligations. This thesis seeks to analyze the effects of the transparency and control a parent company has with regards to interest rates on internal loans. The analysis is conducted by analyzing court cases similar to Diligentia.

The purpose of this study was to increase the understanding of how patients following cerebral vascular attacks percieve personal Control and their ability to influence the course of their rehabilitation. Specific questions relating to the concept of Health Locus of Control such as perception of personal responsibility and own influences as well as the recognition of the influence of outside phenomena such as faith, luck and divine power were asked for. The empirical findings of this study were based upon semistrucutural interviews with five respondents. The results showed that the respondents efforts, together with the efforts of others were a necessity in successful rehabilitation. The influence of faith or luck on the other hand, was not percieved as a factor for success.

This thesis examines a possible control strategy to minimize flow fluctuations in Uppsala?s district heating system. High variations in flow rate may lead to complications caused by hydraulic constraints in the district heating system. These complications, such as inadequate pressure and temperature levels, increase the risk of heat delivery failures. It is therefore important to avoid such situations both for the producer and for the customers.Typically, the forward temperature is controlled by using a rough correlation with respect to the outdoor temperature.

When using the digital halftone proofing systems, a closer print match can be achieved compared to what earlier couldbe done with the analogue proofing systems. These proofing systems possibilities to produce accurate print match canas well lead to producing bad print matches as several print related parameters can be adjusted manually in the systemby the user. Therefore, more advanced knowledge in graphic arts technology is required by the user of the system.The prepress company Colorcraft AB wishes to control that their color proofs always have the right quality. This projectwas started with the purpose to find a quality control metod for Colorcraft´s digital halftone proofing system(Kodak Approval XP4).Using a software who supports spectral measuring combined with a spectrophotometer and a control bar, a qualitycontrol system was assembled. This system detects variations that lies out of the proofing system´s natural deviation.The prerequisite for this quality control system is that the tolerances are defined with consideration taken to the proofingsystems natural deviations.
