Stress och alkoholbruk : En studie om manliga och kvinnliga chefer på en socialförvaltning i Skåne

Occupational stress and the use of alcohol to reduce stress are both separately common in our society. A few researchers have combined the two factors.The aim of this essay was to obtain an increased understanding of how male and female managers estimate their alcohol habits in relation to their occupational stress.We have interviewed nine managers who work at a social services department in Scania. Our main theories were the theory of psychosocial work environment of Lazarus, Karaseks demand/control model, epidemiology- and cultural perspective.Our results were;· Psychosocial work environment contributes to if the interviewed people experienced stress at work.· The grade of control has great influence if the interviewed people experience stress.· There weren't any correlation between stress and increased consumption of alcohol..

Analys av turbulensmodeller för CFD

This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

Prediktiv validitet hos Assessment Centres: en studie av Assessment centre bedömningar utförda av PAT Management för Ericsson Mobile Platforms.

The purpose of this study was to investigate a Swedish assessment centre and more specifically the predictive validity of its assessments of ten managers from a Swedish technological company. The study was made by interviews with these managers' executives in order to find out how well their opinion about their employees matched the assessments made by the assessment centre consultants. The results showed that the congruence of the managers' strengths was 74% whereas that of their weaknesses was 59%..

Barns tolkning av en modell för vattnets kretslopp : -förståelse och tillämpning

AbstractThe purpose of this study is to find out how pupils give expression of a water cycle model and if the model causes any misunderstanding. Two problems constitute the starting point for this investigation. The first question is: how do the pupils explain the water cycle with the help of the jar model (can of glass). The other question is: can the children see any similarities between the can of glass and our earth. Qualitative semi structured interviews with seven pupils in the ages of 8-9 have been used to show the pupils? own thoughts and how they express them.

Transferfunktionsmodeller modellering och prognoser av Sjötransportindex

We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.

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

The purpose of this study is to perform an in-depth analysis of what effects a privatization of a service organization has on the management control system within the organization. The paper studies a service organization which provides service for the county council in Östergötland, Sweden. The result is based on interviews with several people, both within the acquiring private company and also within the county council in Östergötland, and analyzed using Samuelson?s (2005) framework from his study ?Organizational, Governance and Control ?. The major finding in the thesis is that the factors that have had the largest impact on the changes in management control are the new owner demands and the degree of operationalization of the overall goal..

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.

Parametriserad modell av motorprototyp med Solidworks

The purpose of this thesis has been to build a parameterized model of a prototype motor in the program Solidworks, to use in future optimization of aspects of effectiveness and weight. The result were two models. The first model were one minor part of the whole design in 2D, to be able to optimize and study the minor part with a faster loss simulation. The second model was the whole design in 3D. The whole model were done with the three programs Solidworks, Comsol and Matlab.

Internal Control - Efficiency in the Audit Process

The purpose of this research is to examine the implications of the provisions in the Swedish Code of Corporate Governance (the Code) concerning auditor attestation of the internal control report. We will focus on how the auditors? augmented responsibilities will affect the efficiency in the audit process.Our research indicates that the main benefit from reviewing the internal control report is achieving more reliable internal controls, which results in greater prevention of misstatements in the financial statements. This will affect the efficiency in the audit process since the auditor can place more reliance on internal controls when performing audit procedures. This implies that the benefits of preventing misstatements could outweigh the efforts and resources spent on reviewing the internal control report..

Spridning av bekämpningsmedel i banvall : Modellutveckling och känslighetsanalys

The stability of railway embankment is essential for safe transport. In order to ensure safe transport, water should be allowed to freely drain. Furthermore, as the engine driver has to be able to see signs, and people working on the embankment are supposed to easily see flaws on the rails to ensure safety for the passing trains, plants should not be allowed to grow on the embankment. In Sweden there are 12 000 kilometers of railway tracks and 25?30 % of them are treated for weed control every year.

Skolsköterskans arbete utifrån ett salutogent förhållningssätt : en litteraturstudie

The objective of this literature study was to describe how the school nurse can adopt the salutogenic perspective in her health promoting work. The articles were examined in order to identify what was written about the school nurse?s work from the salutogenic perspective. In parallel, Eriksson?s, Orem?s, and Newman?s nursing theories were examined from the same perspective.

Kontrollerad verksamhet? Vilka faktorer påverkar utformningen av intern kontroll i kommunal verksamhet?

The purpose of this essay is to examine which factors that influence the design of internal control in municipal context and how well it works. We choose seven municipals, where we interviewed the administrative managers, the chairmen of the committees and two persons of the staff in each activity unit. The interviews were performed by telephone, due to the keeping of the essay?s timeframe.The theory in our essay comprises eight hypotheses. These hypotheses were operationalised into different variables aiming to make statistical tests possible.

Det är osäkert vad det beror på : Multiprojektstyrning i forsknings- och utvecklingsenheter

BACKGROUND: Project based structures has become more and more common in the organizations of today. As the project based structures are given a more central role in the organizations the interdependencies between the projects are getting more attention. These structures need a new type of control to meet the unique challenges that arise. The researchthat has been done has been concentrated around the project form and the projects internal control, the area of multi-project management is therefore relatively unexplored. The few existing studies on the subject focus on projects in the construction industry why research inmore complex fields of business have been requested.PURPOSE: The purpose of this thesis is to explore and analyze how knowledge intense multi-project organizations manage their project activities, and to determine how different organizational characteristics affect the need for management control systems.METHODOLOGY: The empirical data has been collected through interviews with personnel in BT Products R&D, Gambro R&D and AstraZeneca Development.
