Att förena kontroll med rättigheter : En uppsats om barns rättigheter i relation till kontroll och regler i HVB-hem
This essay discusses children?s rights and control and system of rules in HVB-homes that provide treatment for adolescences with drug abuse problems or criminal behavior. The results of this study are based on interviews with four persons working in managerial positions on different HVB-homes and shows the difficulties of having a children?s rights perspective in a context where a higher level of control is necessary to protect the best interest of the child. The study suggests that the question of balance between children?s right and the need for controlling system of rules needs to be further discussed to improve, and as far as possible guarantee that these adolescence receive best possible care and do not suffer unfair restrictions on liberties..

Broiler production in Zambia - management, growth, diseases and welfare
Successful broiler production in hot climates requires knowledge of how birds are affected by heat stress. It is important with access to water and good ventilation to facilitate coping with the heat. It may be useful to reduce the consumption of feed during the hottest hours of the days, which together with a few hours of extra light available could improve both productivity and animal welfare.
The vision in birds is superior to that of humans and most other mammals. Continuous light and light with low intensity can cause eye injuries, affect the eye development in young chicken negatively, as well as provide increased incidence of foot pad lesions. Access to light affects the production but also the welfare of birds.
Undersökning av mätsystem och regulatorstrukturer för industriella tillämpningar
This thesis is divided in to two different parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of these are based on oversampling: burstsamplingmethod, meanvaluemethod and correlationmethod.
Hur inverkar kontrollbordet på frekvenskurvan vid lyssningsposition i kontrollrummet när placeringar av högtalaren och lyssningsposition placerats efter ITU-R BS.1116-1 rekommendation?
The acoustics in a control room is a complicated phenomenon. Early reflections, reverberation time and area in the room are some of the problems. This report is about the reflection on the mixing console in a control room. The control room being built, these reflections are difficult to take into consideration since the mixing console is one of the very last items you place in the room. This report will explain three main measurements that were done in order to get the answer to the following question: Does the mixing console interfere the frequency curve at listening position? Three measurements were done and the difference between the measurements was that the microphone and the loudspeakers were placed in different places in the control room.
Mappningsstrategi på IKEA:s CDC-lager i Torsvik
This study has been assigned by Bengt Hellman who works at the logistic department at IKEA Torsvik just outside of Jönköping. The task has been to develop a new picking strategy for the Oversize area in the CDC-Warehouse. The reason why IKEA wants a new strategy is because they want to minimize the route length for the forklifts when collecting the orders.By evaluating the current strategies on other areas in the CDC-storehouse, study literature within this subject and look at restrictions for the storing of goods, we have analyzed how the Oversize area works today. We compared the gathered information, to how it should be done according to the literature to be able to work out a new functional strategy.Today, IKEA does not have a working strategy for the oversize area because of lack of time and because all the power has been put on other areas were sales rates are currently higher. This have led to lack of organisation at the Oversize area and items are just put were there is space without first analysing were it should be placed.The strategy that we have worked out and introduced to IKEA builds on easiness of understanding the layout, the employees shall know why an item is placed where it is.
Arbetsmotivation i äldreomsorgen: en explorativ studie av uppfattningar hos medarbetare och chef vid ett äldreboende
An explorative study on the work motivation of employees at a retirement home. The three main factors are internal motivation, external motivation and control. A comparison between how important they estimate the different factors to be and how they experience them today reveals which factor is their key motivator and which areas that need improvement. Results indicat that internal and external motivation are slightly more important than control. And the amount of perceived control reflects the amount of creative and initiative behaviour of the individual.
Hälsoeffekter av patientundervisning och läkemedelsanvändning vid Parkinsons sjukdom
AbstractBackgroundParkinson?s disease is a chronically not curable progressive disease that leads to different degrees of disability. Controlled studies on how patient education influences subjective health in Parkinson?s disease are lacking.AimThe aim of this study was to examine the influence patient education had on drug requirements and on subjective health status of persons with Parkinson?s disease.MethodologyA short form of Health Survey, SF-12, was used to measure perceived health. SF-12 was administered before and one month after patient education (intervention group; n= 48), and in waiting list control (n= 48).
Vad påverkar vuxna observatörers intention att ingripa vid arbetsplatsmobbning?
Arbetsplatsmobbning har omfattande konsekvenser för individer i arbetslivet och samhället. Observatören har en viktig roll i arbetet mot mobbning, då dennes ingripande kan influera andra att göra detsamma. Denna studie undersökte om observatörens kön, locus of control och erfarenhet av observerad mobbning har en påverkan på intentionen att ingripa vid en mobbningssituation. Detta prövades utifrån sex hypoteser och frågeställningen hur relationen ser ut mellan ovangivna variabler i förhållandet till intentionen att ingripa vid mobbning. 165 individer i arbetslivet, varav 114 kvinnor, besvarade en enkät vilken innehöll Rotters The internal-external scale, en justerad Negative Acts Questionnaire-Revised och ett instrument inspirerat av Hektner och Swensons påstående om intentionen att ingripa.
Ekonomistyrning i Svenska fotbollsklubbar
Swedish clubfootball of today involves more money than ever before. This developmentdepends on the higher interest for football in Sweden which generates more revenues fromaudience and TV-contracts, which leads to more money from sponsors and an increasingmarket for selling souvenirs. Despite the fact that the increasing interest has generated morerevenues, we can still see reports in the media about economic problems in some clubs. Whatis the reason for this? Do the clubs have the ability and knowledge about economic controlthat it takes to run such a business as the clubfootball in Sweden has become?Purpose: The purpose of this study is to examine the economic control in a number of clubsplaying in the two Premier Divisons of the Swedish Football League.
Jämförelse av olika reglersystem för undervisningsändamål
Examensarbetet syftar till att jämföra nya alternativ till olika system för användning i laborationer i reglerteknikkurser för olika studentkategorier. Det skall utredas vilket av ett antal alternativ till mjukvaruplattformar som är bäst lämpat att användas vid reglerteknikundervisningen i ITN:s reglerlaboratorium vid Linköpings universitet. Tidigare laborationer i berörda kurser skall även modifieras så att dessa kan genomföras i de nya systemen.Examensarbetet resulterade i en rad modifierade laborationer och system att tillämpa i dessa. De nya systemen medför att all reglering sköts direkt från en dator istället för tidigare variant med externa apparater som programmeras. På så sätt kan större fokus läggas på regleringen i sig och inte de system som tillämpas för att utföra den..
Budgetstyrning och Balanserat styrkort : i form av en kombinationsmodell
Traditional financial management has lately been criticized, since it gives inadequate and unilateral information for decisions and strategy of the operation. The purpose of this essay is to investigate if a balanced scorecard is able to work together with a budget and become a stronger control system for the management. Essential theory underlies the gathering of data as well as the analysis, and the empirical investigation is based on personal interviews. The conclusions drawn from my analysis are that two parallel control systems could complement each other?s weaknesses.
Adaptiv katalysatormodell för reglering
This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

Förekomst & kostnad av kapsprickor i stormaskadad skog
The aim for this study where to investigate the frequency of cutting cracks in saw timber harvested in the storm-damaged forests in regions where the storms Hilde and Ivar hit. The idea for this work came from one of the region?s biggest actors, SCA Skog and Jämtlands district. The purpose where to find out how big proportion of the saw timber that contains cutting cracks, their financial cost in lost wood value and also give advice and suggestions on how to work against the frequency of cutting cracks.
For the field-study some guidelines where used to make sure that the samples were taken under the same conditions, they were:
? The field-study must be performed under harvesting of storm-felled forest, which are horizontal/inclined trunks.
? The averaged sized tree will make it possible to harvest saw timber.
? The trunks can?t be root cut.
A methodology called in Swedish ?Trissmetoden? was used because it is the most frequent used methodology in earlier performed studies and the only one that can be used I field.
Under the field-study data were collected from 570 saw timber logs, 30 logs from each one of the tested harvesters.
