Sambandet mellan kontroll i arbetet, psykologisk flexibilitet och välmående
The work organization variable control and the individual characteristic psychological flexibility are two concepts that affect employees? well-being at work.This cross-sectional study examined the extent to which these variables correlated with burnout, mental health and job satisfaction among homecare workers in Sweden (N=68). As hypothesized, results showed that both control and psychological flexibility were associated with burnout and job satisfaction. Findings also showed that psychological flexibility was associated with mental health. Moreover, the results indicated that there is an interaction effect between control and psychological flexibility in relation to these variables.
Att sjunga en fråga. En jämförelse av tre Query-by-Humming-system och deras användare.
The aim of this study was to compare the Query-by-Humming systems Midomi, Musicline and Tunebot regarding their retrieval effectiveness. The aim was to see if there were differences between the systems but also between the user groups common users, musicians and singers. Query-by-Humming system means that the user sings a tune that the system then use to find the right melody.To compare the systems and their users, queries where collected from the different user groups and replayed for the systems. Mean Reciprocal Rank and Friedman test was used to do the comparison.The results showed that the system did not achieve equivalent and that there were no difference between the user groups. The Mean Reciprocal Rank showed that the systems had very different retrieval effectiveness, where Midomi was the system with best result and Musicline with the lowest result..
Design och implementering av styrlagar för generisk flygplansmodell
For research purposes Saab has developed a generic mathematical model denoted VEGAS of an aircraft with a configuration similar to JAS 39 Gripen. Today parts of Gripen backup control system are used also for VEGAS making the system subject to both corporate and defense secrecy. The main objective of this master thesis is to design, verify and implement public pitch axis flight control system for VEGAS. Furthermore, simplifications regarding the design process is to be examined. Design of pitch axis flight control system for the entire flight envelope has been carried out.
Väderövervakning med övervakningssystemet Uni-View
Företaget Radius Control systems AB sysslar huvudsakligen med utveckling och underhåll av SCADA applikationer. Radius hade önskemål om att kunna visa väderinformation från en väderstation i Radius egna övervakningssystem Uni-View. Detta skulle ske via ABB: s styrsystem AC 800M/ 800xA, med en PM856 processor. Arbetet handlar om att upprätta kommunikation mellan en PLC och väderstation, och från PLC vidare upp till Uni-View. Rapporten behandlar hela arbetsprocessen med början från en prototyp till ett fungerande system.
Kritiska Prestations Indikatorer (KPI), Hur väl fungerar KPI:er som verksamhetsstyrning inom den producerande industrin?
The purpose of this thesis is to examine how key performance indicators are
being used as performance management tools within the production industry.
Specifically the purpose is to investigate how the KPI:s within the
telecommunications industry drives reusability regarding production test
systems.
This thesis will also highlight today?s cost models and suggest improvements of
the KPI and what new ones could be introduced.
A case study at Ericsson AB has been performed.
Private equity företagens styrning av sina portföljbolag.: Två fallstudier av relationen mellan private equity företag och portföljbolag.
The purpose of this thesis is to examine and analyze the characteristics of the management control system private equity firms use to manage their portfolio companies. The thesis takes a share holder value perspective, and it is assumed that the goal of the management control system is to increase the shareholder value in the portfolio company. In a qualitative study two private equity firms and two portfolio companies, one for each private equity firm, were studied in detail. In total, nine in debt interviews were completed. The results from this study suggest that the characteristics of the control system are dependent on the surrounding context; the focus on shareholder value and the specific characteristics of the private equity industry shape the characteristics of the management control system.
Testverktyg för ett automatiserat system
Most often when developing a new system there is a need get a functioning testtool up and running. Including time, cost and resources the solution isn?t always obvious, developing your own or buy one ?of the shelf?. The purpose of this thesis is to study how a general testtool for executing functional tests should be designed to be reusable, be based on recognized knowledge and be able to fast and simple be customized for different types of systems. Key functions from the litterature is presented and used in the design of a testtool prototype.
Ändring av befintligt ridhus : Gävle Fältrittklubb
In past decades information technology has changed the conditions of organizations, not at least within the industry. Advanced IT systems have become a fact in order to cope with rapid changes in the market and to effectively manage an organization?s knowledge. When organizations became more flexible and customized expectations from customers and stakeholders also become higher. These expectations and guidelines are documented in a company?s management system, which can be designed differently depending on what standards the company chooses to implement.

Att skapa ett enhetligt användargränssnitt : Användargränssnitt baserat på personametoden som koncept istället för empiri
Man's life has changed in many ways since technology made it?s entry for public at large. In response to this change the science of human-machine interaction was invented. It has in turn evolved into human-computer interaction. With this science the focus is on the customization of the system for the actual person who will use it.The thesis has been implemented in a telecom company's development department.

Karriärcoaching och dess påverkan på den prestationsbaserade självkänslan.
Karriärcoaching är en tjänst som ökat kraftigt på den svenska marknaden. Tidigare studier inom området har visat att en stark självkänsla stärker en persons hälsa och underlättar för denne att hantera problem. Syftet med studien var att undersöka om karriärcoaching har någon påverkan på prestationsbaserad självkänsla, känslan av kontroll (Locus of Control) samt självbemästring av tankar och känslor (Self-Efficacy). Genom en enkätundersökning har en grupp som genomfört karriärcoaching jämförts med en kontrollgrupp som ej genomfört karriärcoaching. Ett oberoende t-test gav en signifikant skillnad i Locus of Control (p<.05).
Förändring av styrning inom en offentlig stödverksamhet: En studie över hur styrningen förändras inom en offentlig serviceenhet påverkas av en privatisering

Barn och smartphones - En studie av föräldrars attityder kring integritetsaspekten när det gäller barn och smartphones
The purpose of this essay was to sort out parents attitudes concerning children and their use of smartphones, primarily in regards to the integrity-aspect. I have studied if parents believe that their children should have smartphones, if they want to control their use, how they want to control their use and what implications this might have. I've chosen two methods for my research, one quantitative, online questionnaires, and one qualitative, semi-structured interviews. My base has been previous research in the area, to the extent it existed. My findings suggest that parents, on the whole, are positive to letting their children use smartphones but that they?d like some sort of control over their use.
Systemtid eller vårdtid? : En arbetsplatsstudie i vårdens digitala arbetsmiljö
Swedish healthcare systems have endured harsh criticism from healthcare professionals because of their inability to understand healthcare processes. These systems have been identified as significant time consumers, and Swedish healthcare is therefore facing a major challenge to assure patient safety. The following paper is based on a workplace study, which aims to examine healthcare systems? impact on physicians? practices. Our findings show that physicians spend substantial amounts of time chasing information, rather than managing information and pursuing healthcare.
