"... utgå inte från att dom är på ett visst sätt. Fråga dom rakt ut vad som funkar för dom." : En studie om lärares pedagogiska strategier för elever med ADHD

Syftet med denna studie var att undersöka vilka pedagogiska strategier lärare arbetar med när det kommer till elever med ADHD. Studien grundar sig i en kvalitativ metod i form av intervjuer, där sju högstadielärare intervjuades. Alla intervjuer spelades in, för att sedan transkriberas och analyseras. Tydliga mönster i studien visade på att lärare anpassade sin undervisning i den mån de ansåg vara nödvändig. Beroende på lärare och ämne, såg detta olika ut.

Reglerstrategi för fria ventiler : ? Utveckling av en fyrtakts förbränningsmodell för att prediktera optimala ventilinställningar

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

Flervariabel reglering av industrirobot

The goal of this Master thesis has on the one hand been to create a simulation environment for robots, where not only the simulations in this work can be performed, but also similar robot simulations, and on the other hand to study regulators that can increase the possibilities of rejecting disturbances on an industrial robot. The robot model used has three degrees of freedom, corresponding to the three main links on ABB:s IRB7600. The simulation environment is created using Matlab, Simulink, and Robotics Toolbox. It is constructed in a general way and can be used for simulations of other robot objects created in Robotics Toolbox. A gain scheduling is added to the LQ-regulator, where the feedback matrix is varied depending on the arm position in the workspace.

Evaluation of the animal welfare work performed by the licensing committees and a proposal on how to establish an enhanced animal welfare assurance program for the Swedish Trotting Association

According to the basic values of the Swedish Trotting Association the horse and its welfare should always be held in highest consideration. One part of the animal welfare work in the organization is to ensure good horse management practices by controlling all active trainers through the local licensing committees situated at the Swedish racetracks. The Swedish Board of Agriculture stated that high quality animal welfare assurance programs used by the industry organizations can be used in the risk assessment of the official animal welfare control to make the official control work more effective and the ambition of the Swedish Trotting Association is to establish an animal welfare assurance program which may be approved by the Swedish Board of Agriculture. Racehorses are exposed to welfare hazards both in their management as well as during training and racing and factors like handling, training, feedstuff, stable environment, medication and the possibility to express natural behavior all affect the welfare of the horses. The aim of the project is to investigate and evaluate the animal welfare work performed by the licensing committees and to give advice on how to improve the industry?s animal welfare control.

Syftet med denna studie var att utvärdera arbetsmotivation på företaget Norstedts Juridik och att ge underlag för förbättringsarbete. Utvärderingen gjordes med hjälp av en modell för arbetsmotivation, som konstruerades med grund i teori och tidigare forskning. Modellen innefattade åtta dimensioner som tillsammans antogs utgöra arbetsmotivation. Dessa dimensioner var variation, autonomi, signifikans, feedback, utvecklingsmöjligheter, tillhörighet och lojalitet, lön och belöningssystem samt work- life balance. Dimensionerna analyserades i förhållande till de tre bakgrundsvariablerna kön, anställningstid och arbetsenhet och resultaten behandlades i statistikprogrammet SPSS.

ABC+SCM=Sant?

Background:Companies of today commonly search to gain competitive advantages throughout different forms of co-operation, one of which is referred to as Supply Chain Management. Although little research has been assigned to the topic of how to manage and control this type of relation, lately a growing number of academics has been arguing that ABC is an appropriate mean of controlling this type of relationships.Purpose:The purpose of this thesis is to investigate to what degree the ongoing debate on the use of ABC as a mean of control within SCM correspond to the present theories related to ABC and SCM respectively.Research method:The thesis takes it?s starting point within the literature, meaning that the empirical information consists of published articles in the ongoing debate. This information is put in relation to the original theories concerning both topics.Conclusions:The results shown in the thesis in some content agrees with the ongoing debate referring to the positive aspects that could result from using ABC as a mean of control within SCM. However the main result of the study is the discovery of a lack of discussion concerning the problems that implementing ABC within SCM might implicate, a fact that we believe contributes to the mainly positive view on using ABC within Supply Chain Management..

Flödesekonomins dimensioner : supply chain management

It is of increasing importance to in the most effective possible way, manage and control all the transactions of raw materials, products and information that are exchanged between an organization and all its operators. These flows and the need for strategy and managing the processes of planning, implementing and control of the supply chain, has given name to the concept supply chain management. Supply chain management involves all movement and storage of raw material, and all the processes that is needed to manufacture a product from origin to consumption. Globalization, technology and increasing time and quality-based competition are all driving forces behind the concept and reasons for an increasing interest in supply chain management.The purpose of this essay is to by using a qualitative case study examine which decisive success factors that can be identified for effective supply chain management. We have compiled different theories on the subject to use for analyzing a case study Li & Fung, who is a successful supply chain management company.

Hur kan elever bli delaktiga i bedömningsarbetet? Lärares syn på möjligheter och problem i praktiken

Sammanfattning I denna uppsats undersöker jag i kvalitativa intervjuer med tre lärare, på vilket sätt elever i svenska grundskolor (årskurs 7-9) deltar i bedömningsarbetet, och vilka olika problem som lärare upplever i samband med detta. Resultaten visar att de mest framträdande svårigheterna anses vara tidsbristen, och problem i samband med elevers förutsättningar. Tydligt är dock att orsaker till många av dessa problem redan finns grundlagda i arbetet med styrdokumenten och skolorganisationen. Lösningen på många av problemen kan vara utom lärarnas räckvidd, medan andra problem kan minska på längre sikt genom lärares och elevers ökade träning i bedömningsarbetet. En skolutveckling i riktning mot ett ökat elevdeltagande i bedömningen kräver att lärare tydligt kommunicerar med varandra och med eleverna, samt feedback till skolledning och forskning, så att kraven på lärarna kan bli realistiska och arbetsbördan rimlig..

Facilea : hjälpmedel för hemtjänsten

With help from Hälsoteknikcentrum the need for storage of medical items in the home care section has come to our attention by an investigation that Hälsoteknikcentrum did. Facilea and the nursing stuff at Eketånga home care have developed a product specified to improve the work situation for both the nursing staffs and the patients.The trolley is equipped with a special module to make the trolley more adjustable for the recipients and the nursing staffs needs and desires. The product also collect all the care items in one place. Which gives the care patient and its relatives a possibility to gather all the medical items in one place and don?t have to put these in bookshelves etcetera.After surveys, interviews and home visits a prototype was built.

Naturlig haptisk kraftåterkoppling från volymdata

As the volumes are entering the world of computer graphics the pure volume visualisation becomes a more important tool in for example research and medical applications. But the advance in haptics --- force feedback from the computer --- is behind. In volume haptics no equal to the proxy method so popular in surface haptics has yet emerged. Some implementations of volume haptics even use surfaces as intermediate representations so that surface haptics can be used.The intention of this work was to create natural feeling haptic feedback from volumetric density data using pure volume haptics. The haptic algorithm would be implemented in Reachin API for the Reachin Desktop Display, together with other parts to build up a usable volume visualisation environment.To achieve the feeling of stiffness and friction dependent on tissue type, a proxy based method was developed.

Användartester inom webbutveckling : Är användartester nödvändigt vid utveckling av webbplatser?

The aim of this study is to get a deeper understanding about user tests as well as answer the question about if testing for users is necessary at all times. I've done a comparison between what the literature says, and what a company says, about testing. The tests that's been in focus in this study is prototyping and card sorting tests. Prototyping aims to give the developer feedback about the design and check if there are any obvious problems with the design. A card sorting test can be used to get input about how information architecture should be constructed.

Energieffektivisering genom förändrad ekonomistyrning

We have chosen to write our essay in collaboration with Varbergs kommun, where our starting point is to improve energy efficiency by management control. Their occupation separates from a pure profit driven corporation and therefore the management controls have to be adapted accordingly.  The reason why we have chosen to write an essay about the management control opportunities to improve the energy efficiency depends on two different reasons. The first reason is that we find it very interesting, how with support from the management control it is possible to improve different parts of the operation. And the second reason is that Varbergs kommun expressed a wish that they wanted to improve their energy efficiency process.The purpose of the essay is to describe and analyze the opportunities with support from the management control to help improving the process of energy efficiency in a municipal operation.

Kommunicera rätt! - En studie om kommunikation mellan systemutvecklare med kundkontakt och kund

Titel: Kommunicera rätt! ? En studie om kommunikation mellan systemutvecklare med kundkontakt och kund. Författare: Peter Johansson Oskar Hanson Handledare: Johanna Törnquist Examinator: Guohua Bai Problemområde: Anledningen till detta examensarbete är att problem som kan uppstå vid systemutvecklingsprojekt vanligtvis har sin grund i kommunikationen mellan systemutvecklare med kundkontakt och dess kunder. Exempelvis hör en systemutvecklingsgrupp och ett bageri till två vitt skilda yrkesområden och därmed pratar de ?olika språk?, vidare kan det skapas semantiskt brus i kommunikationskanalen som i slutändan kan leda till en felaktig kravspecifikation och de verkliga förändringsbehoven förblir oupptäckta. Hypotes: Examensarbetet baseras på hypotesen: ?Semantiskt brus[1] i kommunikationskanalen[2], otillräcklig negativ feedback[3] från sändare[4] och mottagare[5] och svårighet att hitta rätt nivå på samtalet med hjälp av kodning[6] och avkodning[7] ger upphov till en felaktig bild av kundens verkliga förändringsbehov[8] .? Slutsats: Alla delar ur Shannons kommunikationsmodell tillsammans med cybernetikens negativa feedback påverkar resultatet vid framtagande av kravspecifikation. Delar som både teori och respondenter tar upp är att som konsult måste denne ?kunna tala kundens språk?, hitta rätt nivå på samtalet, ge och ta negativ feedback samt undvika semantiskt brus i kommunikationskanalen.
