The study also aims to examine more closely how this objective applies to the studied resource schools in the studied municipality, as well as highlighting the success factors and barriers that exist to achieve the goal. Previous studies show that this kind of Differential practice tends to become a permanent solution.
Developing Dynamic Outsourcing - Bringing continuous added value to the ABB Full Service partnership
Executive summary This master thesis was originally based on a specific assignment given to the authors from ABB Full Service, a unit specializing in providing maintenance outsourcing: ?How can ABB Full Service expand its offering of providing fundamental maintenance by seamlessly incorporating the business concept with competencies and solutions from other ABB divisions?? The academic issue was developed throughout the thesis, resulting in the following formulation: ?From an organizational perspective; how can service providers bring continuous added value to intra-organizational outsourcing partnerships?? Many of the key findings of this thesis are reflected in the issue. The term intra-organizational outsourcing is a proposed addition to the terminology in the academic discourse on outsourcing. The definition of the term is: ? Where an organization outsources a business process interlinked with the physical operations, requiring the service provider to take over a preexisting unit and its employees.This is an accurate description of the form of outsourcing that ABB Full Service is engaged in.
Användarupplevelse inom mobila applikationer : En kvalitativ utvärdering av en befintlig utvärderingsmetodiks funktionalitet i en mobil kontext
Choosing the right user experience evaluation method can be difficult, choosing the right one for mobile user experience can be even more so. One major cause is that mobile usage is context dependent. Another contributing factor is that there is not one widely adopted theory or framework for user experience due to its complexity.The purpose of this study was to evaluate an existing method artifact in its feasibility for evaluating mobile applications. The chosen method, AttrakDiff2 is a self-reporting semantic Differential questionnaire to evaluate the user experience of an interactive product, based on its hedonic and pragmatic qualities.A study was conducted where the participants assessed one mobile and one web application, which were later rated with AttrakDiff2. The completion of the questionnaire was conducted as a think-aloud session subsequently followed by an interview.The results suggest that the participants experience was affected more by the evaluated application style than the different platforms.
Implementering av höghastighetsgränssnitt i 0,15 µm halvledarprocess
This study investigated the possibility of implementing three standards, Transistion Minimized Differential Signaling (TMDS) and two versions of Stub Series Terminated Logic (SSTL), for inter-chip communication in a specific manufacturing process. The two SSTL standards were implemented in one transceiver system while TMDS was implemented in a separate system. The evaluation was done with Spice simulations on schematic level with some parasitic capacitance and resistance. The idea was to investigate the possibility of implementing these standards and get an idea of eventual shortcomings. In order to create models as a basis for evaluation, simulation environments with models for circuit board and packages were created and transmitters and receivers were designed.
Design av PID-regulator baserad på kommersiell processormodul
The idea to develop a platform for a PID-controller came from the need to control the temperature in an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, Differential amplifiers and a two channel Analog-to-Digital converter was fabricated.
Undersökning av genuttrycket av homeoboxen HOX A6 vid pyometra samt försök att bygga upp en in vitro-modell för pyometra
This study had two different aims. The main aim was to investigate the dynamics and impact of African swine fever (ASF) on a farm in Uganda during a recent outbreak through a case study. The second aim was to estimate the presence of two important Differential diagnoses of ASF: Classical swine fever (CSF) and Porcine Reproduction and Respiratory syndrome (PRRS).The field and laboratory based case study of the farm level dynamics of ASF virus during a recent outbreak (October-December 2010) on a farm in the district of Mityana, Uganda, was conducted, using interviews, ELISA and RT-PCR. The financial impact on the farm was also estimated. The impact of the outbreak was profound.
Varför kriminell? : En kvalitativ studie om unga mäns väg in i kriminaliteten
I denna studie används en kvalitativ metod i form av intervjuer med fem unga män som har ett kriminellt förflutet. Syftet med studien är att ta reda på vilka faktorer som kan ha påverkat dessa unga män in i en kriminell livsstil. Studien syftar även till att söka svar på varför dessa unga män väljer att stanna kvar i det kriminella livet. Genom att analysera det empiriska materialet vi fått in genom intervjuer med dessa unga män tillsammans med teorier som Nätverksteorin, teorin om ?Differential associations? samt Avvikelseteorin har vi kommit fram till flera aspekter kring vårt syfte.
Vad ?r en funktion?
The concept of function represents a major part of mathematics and becomes more significant
in school during high school. Throughout history, it has been a difficult concept to define and
may create challenges for contemporary students. This literature study aims to identify students'
difficulties with the concept of function, as well as to account for how the definition of a
function has evolved historically. The literature study has been conducted through database
searches in ERIC, Education Research Complete and MathSciNet via EBSCOhost, as well as
through chain searching. The study results in identifying that students' difficulties with the
concept of function primarily include the graphical and algebraic forms of representation.
Kännedom om och handhavande av Vocal Cord Dysfunction : bland logopeder och läkare i Sverige
Vocal Cord Dysfunction (VCD) is characterized by paradoxical vocal cord movement during inspiration or expiration, and generally affects adolescents and predominantly women. Previous studies have shown a large inconsistency concerning terminology, definitions, etiology, assessment, Differential diagnosis, co-morbidity and treatment. The purpose of this study was to map knowledge on and management of VCD in Sweden. The study was conducted as a written survey addressed to speech-language pathologists and physicians, and attained an answer percentage of 79 percent. The results showed that several professions were involved in the management of these patients, but no clear pattern of referral could be observed.
Trovärdig uthållighet : Differentierad uthållighet ? soldatens överlevnad
Försvarsmakten beskriver i Arméns utvecklingsplan 2010-2020 att tre dygns uthållighet på taktisknivå inte är tillräckligt utan bör vara mer flexibelt så att den även passar mindre enheter som skall kunna verka över stora avstånd utan möjlighet till egen logistik. Syftet med uppsatsen är att utreda vad trovärdig uthållighet är. Att utreda om tre dygns uthållighet på taktisk nivå är tillräckligt eller om denna bör utökas till mer än tre dygn. I uppsatsen beskrivs vad som står skrivet i olika dokument från Försvarsmakten vilka styr uthålligheten. Det beskrivs även hur Försvarsmakten avser att uthålligheten skall se ut i framtiden.

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.
Hållbarhetsredovisningens budskap : en komparativ studie av Vattenfall och E.ON
Companies today are expected to communicate their responsibility to the world around them. Society?s expectations differ and stakeholders are demanding that companies act responsibly on matters related to climate, work environment and human rights. The purpose of sustainability reports is that companies should measure, present and take responsibility in relation to their internal and external stakeholders. It is intended that a reasonable picture of the company's sustainability performance should be communicated, containing both positive and negative effects.Companies efforts with sustainability issues is industry-dependent and industries with significant environmental problems perform the most advanced environmental statement.
Stabila bakfyllningar
Fyllning i kakor (s.k. bakfyllning) kan under bakning och särskilt under lagring ge negativa effekter så som migrering av fyllning och olja ut i kakdegen. Valet av fettsystem i fyllningen och dess smältpunkt är av stor betydelse för att erhålla önskvärd konsistens och textur. Syftet med examensarbetet var att minimera dessa negativa effekter samt att kartlägga faktorer som påverkar detta. Tidigare bakförsök vid AarhusKarlshamn har visat att fyllningens partikelstorlek påverkar migreringen, då migreringen tycks öka med ökande partikelstorlek.
The effect of vegetable fat on cheese yield and cheese properties
The production of cheese is in continuous development with objectives to in-crease productivity, achieve changes in shelf life and functional properties of the products. One concept in the development is to substitute milk fat with vegetable fats and oils in the manufacture of cheese.
The objective of this study was to investigate effects on cheese yield and cheese quality of 4 different semi-hard analogue cheese products produced by substituting milk fat with vegetable fat, each analogue cheese with a specific mixture of vegeta-ble fat. As reference a cheese produced with anhydrous milk fat was used.
The yield and recovery of fat and protein were determined by recording the weights of each cheese direct after press and after 20±2 days of storage and analysis of the composition of the cheeses after 20±2 days of storage. The cheese was fur-ther subjected for texture profile analysis in a TA-XT Plus Texture Analyser and analysed with Differential Scanning Calorimetry (DSC) to examine whether the fat behaves similar in the cheese as in pure form in respect to its thermal properties.
The cheese yield was not significantly different when using different fats. Differ-ent amounts of water were absorbed during the water cooling.
