Projektuppföljning - En studie av relationen mellan projektuppföljning och organisationsstruktur

This paper aims to examine performance monitoring in project organisations. The number of organisations that regularly performs projects as a key part of their operations grows rapidly, why this topic has become of large interest. Through a theoretical framework developed by Lars Östman in 1977, the performance monitoring system of the Swedish government-owned public utility Svenska Kraftnät is studied closely. The results from this analysis are then linked to an analysis of the organisation's internal structure through Mintzbergs generic organisational structures. Close connections are found between organisational structure and performance monitoring, which leads on to interesting observations about the connection between size of a project organisation and choice of monitoring method..

Diskkrypteringsprestanda i GNU/Linux

This thesis compares the impact on disk performance in a GNU/Linux  environmentwith three encryption algorithms: AES,  Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that  is  drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..

Mätmetoder och nyckeltal: en kvalitativ studie om hur bibliotekschefer mäter bibliotek

The aim of this master?s thesis is to examine how managers in some public libraries are using performance measurements and to what extent decision making is based on the results. The main questions posed are:??What performance measurements and indicators are used in the libraries examined???What is the attitude towards performance measurements among library managers???How and to what extent are performance measurements and indicators used in the process of decision making???What improvement would library managers wish regarding the development of performance measurements in public libraries?The theory is based on a model of evaluation of the public sector in addition to general steps of evaluation of quality and performance measurement results. The investigation is based on qualitative interviews with seven managers of public libraries in Sweden.

Optimering av slutfasstyrning

Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.

Performance Management i E-handel

Too much attention has been given to mainstream approaches in performance management and management accounting research, without taking in to account changes in the environment with the rapid growth of online retailing. This paper evaluates how and/or if performance management differs in online contexts by using a conceptual model developed by Ferreira et al (2009). The model and its components are tested on three multichannel- and six e-commerce businesses. The result and its analysis is commented on by two e - commerce experts. The result shows that the operation method of the models twelve components do not differ in terms of work methods in online and offline contexts.

OSE och Linux : En studie om prestanda

There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..

Medarbetarsamtal : -en studie om medarbetarsamtalets betydelse som verktyg för utveckling inom offentligsektor

 Performance appraisals- a study of the performance appraisals significance as a tool for development in the public sector.Anders Larsson and Åsalill OlssonPerformance appraisals have been given a central role in leading businesses in the public sector and are seen as a tool to create development opportunities and achieve better results. This has resulted that performance appraisal in many organizations takes up capacity and time. This was the starting point of our interest to study whether the time spent on performance appraisals effectively pays for itself in the organization, in other words whether the effects expected actually are achieved. The paper examines first line managers` views on staff appraisal purposes and effects of a function within the Landstinget. The survey design, methodology and transaction are of qualitative and quantitative method with three different sources: literature review of previous research, interviews with first line managers in Landstinget Västmanland and the results from an employee satisfaction survey conducted on behalf of Landstinget Västmanland.

EN TOTALKOSTNADSJÄMFÖRELSE MELLAN CELL-, SKUM- OCH LECA-BETONG

This report provides a comparison between the products cellular concrete, foam concrete and LECA concrete. The questions to be answered during the work is how the cellular concrete stands up in cost terms to the existing competitors on the market, how the concrete products differ in design work, and in which situations the concrete varieties are preferred to use.Cellular concrete is a variant of ordinary concrete, with the difference that the ballast is exchanged from stone materials to expanded polystyrene beads (EPS). This substitution gives a product with higher insulation values but lower weight than ordinary concrete.The work was carried out by designing a survey which was sent to two hundred randomly chosen companies across Sweden, to see the building industry?s opinion of the product cellular concrete. The survey showed that cellular concrete was equals its competitors in terms of price, while the product was said to be more flexible, quicker and easier to cast.Then some of the companies, who participated in the survey, were interviewed to see more carefully, how the price, the workmanship and the time for casting and dehydration differed between the products.

Lärarrollen i förändring : En intervjustudie om lärares inställning till en förändrad lärarroll

During the past twenty years, the Swedish school systems have slowly changed to becomemore and more performance-driven. Private schools have been growing in general and, likeindependent schools and schools managed by municipalities, they profile themselves. Schoolsare becoming more performance and result-oriented, which has changed the roles of teachersin a dramatic way and is in general, still changing.By profiling students based on theirindividual performance, schools are able to help students identify themselves and their owngoals. The process of profiling is a slow one in which some teachers adapt more quickly thanothers, and one that is critical for other teachers to learn in order to keep up with the demandsof society.Schools, like ordinary businesses, are in constant competition with each other to keep up withthe newest and greatest models of teaching and to rank among the best in high achievements.Perhaps the downside of this modern school structure is that it is often difficult to have aschool where both school management and teachers see eye to eye. School management must heavily focus on the school?s results as a whole.

INDIVIDUELLT LÄRANDE I TEAM - En studie av lärstilars inverkan på lärande, effektivitet och prestation

Organizational learning has become more and more important in the last decades as the environment in which organizations exist continues to change rapidly and unexpectedly. In order for organizational learning to happen, the individuals within the organization must learn. Just as different individuals possess different skills, each individual also has their own learning style. As the use of teamwork increases, so does the need for techniques to put high performing teams together and with organizational learning as one of the objectives the question is, how do we maximize learning, efficiency and performance in teams? This study uses a quantitative method to examine how teams, from a course at the Stockholm School of Economics, perform on the individual learning, team efficiency and team performance scale based on the individual learning styles within the team.

Den relativa viktens (kalv/ko) inflytande på kalvningsegenskaperna hos SRB och SLB :

Difficult calvings and stillbirths are problems in Swedish dairy production that result in large expenses for the farmers and welfare issues concerning the animals. A common opinion is that the live weight of SRB and SLB is increasing, and whether increased weights have caused the increase in calving problems has been discussed. The aim of this study was to investigate the relationship between the relative birth weight (calf/cow) and calving difficulty and stillbirth, respectively. The importance of breed and parity for the relative weight has been investigated, and comparisons with previous studies have been made to evaluate whether the relative weight has changed over the last decades or not. The study was based on 807 calvings, registered during the period 1993-2003 in the experimental dairy herd of the Swedish University of Agricultural Sciences (Jälla).

Hur påverkar en lansering av EMV det ekonomiska resultatet i en kategori -En kvantitativ studie om EMV lanseringar i sällanköpshandeln-
