Kontraktsstyrning och kvalitetsindikatorers utformning vid kommunal upphandling : En flerfallsstudie
Management by contract is nowadays a common method within the public sector since the NPM overtook as paradigm with its mechanisms of control inspired by the private sector. The public agency is foremost a service provider where they interact with citizens in the service process. Swedish eldercare has significantly increased its expose to competition which means that eldercare can be executed not only by the municipalities own provider. Such an adaption increases the requirements to inspect quality and how the purchasers assure goal achievement by control. The outmost liability stays with the municipality to ensure that the service produces god care since their position as the service purchaser implies the responsibility to plan, precise and evaluate the required work that the executor has to accomplish.
Skolan - klassfrämjande eller klassutjämnande : En undersökning om vad tre lärare tänker om elevers hanterande av den ansvarstagande elevrollen.
Children from different backgrounds, cultures and home environments attend school everyday. The educational system of today focus on the importance for every individual pupil to take responsibility, in order to gain knowledge. From an early age should the pupils learn how to work independant and take responsibility for their education. My questian, and what I have decided to discuss in this paper, is wether everyone has the same opportunity to gain knowlwdge and learn trough this method. In preperation for this essay I read litterature where the authors claims that this kind of educational system is not for everyone, but it benefits those pupils that comes from a middleclass background.So, is our school system fair and equal? Can everyone, no matter what social and cultural group they belong to, get the education thay have right to? In order to get a deeper understanding I interviewed three teachers that works in different schools.
Energisparläge i automationsindustrin : Potential för att minska tomgångsförluster med industriella styrsystem
Former studies have shown that a considerable part of industries? energy usage can stem from idle times in the production. This thesis, carried out at Siemens Industry sector, evaluates the potential for using the control system to automatically put machines into energy saving mode during idle times. The main part of the thesis consists of a case study performed on machine tools at a Scania production site in Södertälje. Through load measurements the potential for energy savings was determined.The results show that there is a great potential for energy savings during idle times at the site.
Vilken nutritionsbehandling har bäst effekt på tillväxten hos barn födda för tidigt och/eller med låg födelsevikt?
Sahlgrenska Academy at University of GothenburgDepartment of Internal Medicine and Clinical NutritionTitle: ?What nutrition therapy has the best outcome on growth in preterm children and/or children born with low birth weight??Author: Josefine Nyström and Rebecca HammarSupervisor: Fredrik BertzExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 11, 2013Background: There is a number of reasons why a child is born preterm and with a low birth weight, for instance if the mother is underweight, smoking or exposed for malaria. The negative consequences of being born preterm or with a low birth weigth are many, both on long and short term. According to the WHO preterm birth is the most common direct cause of infant mortality. By providing the right measures in time when it comes to nutrition the mortality can be reduced considerably.Objective: To examine and summarise the scientific ground when it comes to the best nutrition therapy for preterm children and children born with a low birth weight.Search strategy: A systematic literature search was done in the databases Pubmed, Cohrane and Scopus.
Vegetationens roll i erosiva vattendrag : en review och fältstudie av två nyckelområden i Rönne å
The vegetation?s impact on erosion control is widely explored, even though research? results are scattered where it suggests a both positive and negative relationship between roots and erosion tendency. Research has measured the roots? impact on erosion by many different methods, hence the aim of this study is to offer a clearance of what factors play an important role in the choice of appropriate species controlling river bank erosion. I have therefore
studied 17 articles concerning vegetation and erosion control, which were found in different databases such as: Web of Knowledge, Biological Sciences, Academic Search Elite and Google Scholar.
Det Intelligenta Huset : - En studie i hemautomation
Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.
Spenarnas kondition i automatiska mjölkningssystem : en studie av två spensprayer
Two post milkning teat dips (PMTD´s) were compared in an automatic milking system at Kungsängen Research Farm, owned by SLU (Swedish University of Agriculture) in Uppsala. In the experiment an evaluation system was used where teat condition regarding skin and teat ends was graded according to a scale where 1 was the best score and 5 the worst. The evaluation period was almost six months in total devided into four minor experimental periods. The technician scoring the teats did not know which PMTD that was currently used. Statistical analysis showed a significant difference between the two PMTD´s regarding teat skin condition, but not regarding teat ends.
Private equity - styrning av tre portföljbolag; En komparativ fallstudie av ett buyout-bolags styrning av tre portföljbolag
By identifying effects that a buyout-firm has on management control systems in its portfolio companies, the aim of this thesis is to explain how such effects differs between the companies and finally to explain why the effects differs even though the companies are owned by the same buyout-firm. The study is conducted as a qualitative case study based on interviews with representatives from the studied buyout-firm and three of its portfolio companies.By analyzing the empirical findings with frameworks and theories within management control systems and value creation, we cannot only identify effects that are common for all portfolio companies but we can also observe differences between the portfolio companies.The identified effects that are common for all portfolio companies are: increased internal reporting burden, increased perceived risk of getting laid off among managers and co-workers and replacement of the board immediately after acquisition.The effects that are observed only for two portfolio companies are: increased focus on short-term planning, higher financial targets, replacement of company management upon acquisition and moving of decision authorities to higher organizational levels. Differences are observed although the portfolio companies are owned by the same buyout-firm due to: differences in management and co-workers equity stake in the portfolio companies, differences in business complexity and differences in planned exit-horizon..

System specialists and technicians will use the prototype. The Simulator should give the user a technical demonstration on how components work in a door system. The proto- type consists of motor, switch, relay and sensor.
Inokulering med två hjorttryfflar på arginingödslade täckrotsplantor i Gideå plantskola :
The effect of inoculation on containerized pine and spruce seedlings in a nursery with two
ectomycorrhizal fungi was investigated in regard to the development of mycorrhiza and plant growth. The fungi were Elaphomyces muricatus and Elaphomyces granulates and the inoculated seedlings were compared to an uninoculated control. These seedlings were all fertilized with arginine.
Five mycorrhiza species were found after DNA sequencing of the mycorrhizal root tips with different found morphotypes on seedlings from all treatments. Thelephora terrestris was the type which had the greatest distribution on pine seedlings and Tylospora asterophora was found at big extent on spruce seedlings. The inoculated species was not found, if it was due to the species hadn?t colonized the roots or if the DNA sequencing failed we can only speculate about.
Tredjemanskontroll - Säker rätt är säkert rättssäker : En studie med utgångspunkt i betänkandet Förbudet mot dubbla förfaranden och andra rättssäkerhetsfrågor i skatteförfarandet (SOU 2013:62)
SKV and Tullverket have several important tools and methods available in each activity to ensure that taxes and fees are paid and charged rightfully. Among other things they use tax or customs surcharges, targeted and general third party injunctions or targeted and general third party audits. The targeted controls, ergo targeted injunctions and audits, are targeted towards specific persons or documents while during the general controls these are not specified. The methods have repeatedly been the subject of discussions and attempts to simplify the tax procedure and increase the Rule of Law for the individual.The government appointed a commission on March 8 of the year 2012 with the assignment to prepare proposals to increase the Rule of Law in the tax procedure. The assignment was therefore to analyze the areas of tax and customs injunctions, reimbursement because of expenses and agents and also third party controls.
Halvledare för höga strömmar i fordon
Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.
LÖNSAMHETSKALKYL AV FUKTSÄKERHETSANSVARIG VID RENOVERING : En fallstudie av ett projekt där ByggaF-metoden har använts
The so called ?ByggaF-method? is a relatively new Swedish method to stop moisture from being built into a building. The method should prevent damages on buildings as a result of mould growth and moisture. The purpose of the method is to include moisture control in the entire constructionprocess, from the projecting phase and all the way to the management phase. Up until now, there is no proof if the method is profitable or not and no studies have been made on the topic.
Vision om jämställdhet - en illision?? : En kvalitativ studie om jämställdhet inom samboförhållanden.
This qualitative study was conducted to investigate how subordination and superiority emerges in the interaction between heterosexual couples between 20 to 30 years old, without children. Eight semi-structured interviews with four couples have been conducted to provide insight into how subordination and superiority is made in the interaction between the cohabiting couples. All interviews were transcribed and then manually categorized along specific main themes and sub themes. The empirical data were then assayed by a hermeneutic interpretation. Three previous studies have formed the basis for this study, Det kallas kärlek by Carin Holmberg, the anthology, Jämställdhetens pris and Familjer i tiden by Christine Roman and Helen Peterson. The theoretical framework consists symbolic interactionism, and especially the concept of asymmetrical role-taking and also doing gender.
Vad är verklig kostnad per koplats? :
Purpose
There are almost infinite numbers of ways to build dairy farms in Sweden. When building a new free stall barn you have the possibility to affect both working environment and animal welfare for many years to come. The construction costs are influenced by which type of barn that is built and what functions it contains, for example one can predict that automatic milking systems are more expensive to integrate than milking parlours. But what is the real cost of today for the construction of free stall barns with milking centres and how is it affected by construction methods and functions? Is the labour time influenced by the building costs? These are some of the questions this report will try to answer.
