ACTa våra stressade lärare: en randomiserad studie om Acceptance & Commitment Therapy (ACT) för stressade lärare
The present study examines the effect of a nine-hour Acceptance and Commitment Training (ACT) intervention for teachers who experience stress. Twenty-two teachers from four different counties in southern Sweden were randomly allocated to an ACT intervention (n=15) and a control group (n=7). The ACT condition received three three-hour sessions of ACT over a six-week period, and the control group received a three-hour stress lecture at one occasion. At a follow-up four-weeks after completed intervention, ACT participants showed significant in-group differences on stress, psychological flexibility, general health, and burnout. At a between group comparison, only psychological flexibility was significantly enhanced at the follow-up.

Släpmål 10: Konstruktion av släpmål till flygande målrobot
Detta examensarbete har utförts på uppdrag av Vidsel Test Range (VTR) som är en del av Försvarets Materielverk.På Vidsel Test Range testas och verifieras bl.a. jakt-, attack- och luftvärnsrobotar.Ett sätt som används för att simulera ett verkligt mål är att flyga ett obemannat fjärrstyrt flygplan, kallat målrobot. Från målroboten vinschas ett mål ut, kallat släpmål. Skott sker sedan mot släpmålet. Största anledningen till att använda sig av ett släpmål istället för att skjuta på målroboten är att kostnaden blir mindre.Projektets syfte var att återuppta utvecklingsarbetet av ett nytt släpmål baserat på en tidigare tillverkad del av höljet på släpmålet.
Reglering av matarsystem vid höghastighetskapning
Today small metal parts are mass-produced as for example rollers in cylinder bearings. At high velocity cutting the metal is cut with a great force in a scissor-like device. Both precision and repeatability is important to be able to guarantee good quality, but from an economical point of view it is also important to keep a great manufacturing capacity. The part of the process that is most time consuming is when the metal bar, that is about to be cut, is fed to the right position. Therefore it is interesting to examine if the time used for positioning can be reduced.
OMT-A : An Extension of OMT to Model Active Rules
Today there are commercially available databases with active features, i.e. active mechanisms are available for development of information systems. But the usage of active mechanisms is low in practice. This is due to the insufficient methodological support in analysis and design for developing ECA rule based software. It has been proposed that one of the most suitable ways to tackle this problem is not to develop new methods but to extend existing methodologies.In this thesis an extension of the Object Modeling Technique (OMT) is developed, called OMT-A, which is able to model active rules.
Faktorer som påverkar sjuksköterskans följsamhet till riktlinjer : En litteraturstudie
Cross infection is a global health problem. The cost for cross infection increases every year. Florence Nightingale focused her attention on preventing cross infections by using good hygiene and as a nurse that is one of your more important tasks. Nurses have guidelines for how hygiene should be implemented in practice. The aim of this study is to investigate factors that influence nurses´ compliance to guidelines regarding hygiene.
Finns det någon koppling mellanpersonrelaterade egenskaper (personlighetsdrag, locus of control, ålder eller kön) och stark ångestsymtom?
Studien undersöker relationer mellan stark ångestsymtom och personlighetsdrag samt bakgrundsfaktorer. 35 deltagare, 23 kvinnor och 12 män, rekryterades på en högskola och besvarade en enkät.Resultaten visar en stark relation mellan personlighetsdraget neuroticism och ångest men inga andra korrelationer med övriga faktorer. En djupare analys av resultaten tyder på att den population ur vilken deltagarna rekryterats inte varit lämplig för att undersöka de aktuella frågeställningarna, eftersom deltagarna uppvisat en mycket låg grad av ångest i testet och även en mycket hög grad av inre locus of control. Diskussionen har väckt frågor anknutna till instrumentens lämplighet och beskaffenhet, men också om olika relationer i personligheten kan tänkas gälla för grupper som ligger på hög respektive låg nivå av ångest. En slutsats av detta arbete är att frågan är viktig och intressant och att det finns tillräckligt med teoretiskt underlag för att återkomma med ett mer omfattande val av deltagare och lämpligare mätverktyg..

Ecolean Development AB are developing and manufacturing filling machines for pasteurized liquid food products. Because of lack of any appropriate supplier of box closer which seals boxes with small flaps, they have decided to start a project to develop a prototype of a box closer. Due to long experience from industrial automation I have been given a chance to develop control system for a box closer. Degree thesis involves electric design in ELPROCAD ic PRO and programming of PLC (programmable logic controller) and HMI (Human Machine Interface). The report describes degree project from the project plan phase via the development phase to the conclusions.
BIG SISTER IS WATCHING? En argumentationsanalys av den svenska debatten om ?Chat Control?
The Swedish debate regarding chat control highlights a value conflict between protecting the
safety of children and preserving democratic rights such as privacy and freedom of expression.
This thesis examines key arguments for and against the proposed EU CSAM-regulation,
analyzing them through a normative argumentation analysis method. The analysis is based on
the Swedish constitution, representing the common values of Swedish society. The study
reconstructs arguments from four debate articles and evaluate them according to their relevance
and validity, which makes up the arguments? total evidential strength.
Energieffektivisering av luftningssteget på Käppalaverket, Lidingö
This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.
Att snusa eller inte snusa : Omgivande påverkansfaktorer på svenska snusares attityder
The purpose of this essay has been to examine whether attitudes and behavior among Swedish people who takes snuff are dissonant or not and how their attitudes are affected by the media debate about the health risks snuff can cause. Furthermore, we were interested in finding out how different reference groups´ attitudes would influence the attitudes and the willingness of people to stop taking snuff and investigate how much control the people who take snuff think they have. To answer these questions we chose to ask primarily students at Stockholm University and Södertörns Högskola. The students were asked to fill out a questionnaire with 22 questions and the 100 responses we collected were worked up in a statistic program, SPSS, on the computer. The main models used for the essay and for the questionnaire were the Theory of Planned behavior and the Dissonance theory.
Hårda män i mörka kostymer : - En bildanalytisk studie med utgångspunkt i genus
The purpose of this study has been to examine how the media presents policymakers from a gender perspective. We have made an analysis on the basis of genderdichotomies. We have studied images from the Swedish newspaper Svenska Dagbladet as well as the French newspaper Le Monde in order to achieve a greater understanding in which way the both medias contributes to the reproduction of gender in the media.The conclusion of the study has shown that the gender system is somewhat confirmed by the way in which men and women are presented in the medias. Men are presented with more traditional gender related associations than women who is shown in a more dynamic constellation, this is mostly evident in the Swedish newspaper Svenska Dagbladet..
Röstpremien - premien för aktiens rösträtt
This thesis aims to investigate the voting premium for companies differentiating voting rights between share classes on the Stockholm Stock Exchange. The voting premium represents the value of a vote attached to the share. The voting premium can be estimated from the price premium between two listed share classes with differentiated voting rights. Rydqvist's dissertation (1987) serves as a model for this study which investigates whether the theory of the so called "oceanic games", along with a proxy variable for cost of control, can predict the voting premium during 2010-2012. To the original model developed by Rydqvist, control variables for differences in liquidity between share classes are added to investigate for an increase in the explanatory power.
Utfackningsväggar ur lufttäthets- och fuktsäkerhetsperspektiv : En jämförelse mellan platsbyggda och prefabriceradeutfackningsväggar
The swedish national board of housing, Building and Planning,recommends that all stakeholders in the construction industryperform a moisture control design to make sure that the buildingachieves good moisture resistance. Since June 1, 2006 there are nospecific requirements or quantitative values for air leakage.Although the swedish national board of housing does presentrequirement that the building envelope must be sealed so that theclient?s requirements for specific energy consumption and installedelectric power for heating purposes are met. Despite this, studiesfrom SP shows that few buildings meet the client?s requirements inspecific energy, which increases the risk of occurrence ofcondensation-related moisture damage.This study aims to evaluate curtain walls connections from airsecurity and moisture safety.
Alternativa produktionsmetoder vid anläggningsarbeten Kringgjutning av el- och telekabelkanalisation
I dagens samhälle blir det allt mer intressant att spara energi, dels med tanke på miljön och dels föratt minska på utgifterna. Denna energi ska sparas på ett sådant sätt att effekten för användarna blirså liten som möjligt.I denna rapport beskrivs hur ett reglersystem kan byggas för att minska energiförbrukningen hosväxthus genom att reglera belysningen på ett effektivt sätt. Systemet är helt automatiskt vilket göratt användarna inte behöver tänka på styrningen av lamporna alls när väl systemet är uppsatt ochkonfigurerat.För att styra lamporna på ett bra sätt mäts det inkommande ljuset med en PAR-sensor. Lampornatänds och släcks därefter beroende på ljusmängden och även på hur varmt, eller kallt, det är iväxthusen.Styrningen av belysningen sker med en mikrokontroller från Microchip, en PIC18F4620 som ärprogrammerad i C18. Kringkomponenter som portexpasioner, klocka och reläer användes också föratt bygga ett bra reglersystem.Resultatet är att det är möjligt att bygga ett reglersystem med begränsad budget som styr lampornapå ett effektivt sätt.
