Sångideal ? stjälp eller hjälp? : En studie ur pedagogens perspektiv om hur dagens sångideal påverkar unga sångröster
Denna uppsats behandlar fenomenet organisationskultur, och undersöker hur organisationskulturen kan ha kommit att förändrats på ett företag i samband med en organisationsförändring i form av ett uppköp. Detta undersöks genom att två valda teoretiska ramverk används, och att aspekter som tid och förändring inkluderas i studien. Studien genomförs i form av en kvalitativ fallstudie på ett enskilt företag, där semistrukturerade intervjuer av anställda gjorts.Uppsatsen syftar till att undersöka hur bättre förståelse av organisationskultur kan erhållas när en kombination av två teoretiska modeller appliceras i samband med att en organisationsförändring har skett, där det både tas hänsyn till interna nivåer och externa faktorer.Studien visade att en rad olika förändringar gällande organisationskulturen har skett efter det att organisationsförändringen har ägt rum. Studien kan sägas ha bidragit till en djupare förståelse för organisationskultur som enskilt fenomen, och hur fenomenet på olika sätt kan påverkas. .
?Det är inte bara socialtjänstlagen som styr vårt jobb? : En kvalitativ studie av åtta socialsekreterares upplevelser av handlingsfriheten i det dagliga arbetet
The overall aim of this study is to investigate how social workers who are dealing with financial assistance are experiencing discretion in their daily work. The aim of the study is also to examine how social workers who are dealing with financial assistance relates to the controlling and the supporting functions of their daily work and how this in turn affects the attitude to the client. In order to examine the aim of the study, qualitative method was used. Eight social workers have been interviewed and presented with two fictitious cases that they have been able to discuss. Theories regarding the street-level bureaucrat and its discretion have been used to interpret and understand the collected material.
Validering av Inertial Measurment Units som insamlare av data för drivande av OpenSim-modell
The purpose of this paper is to investigate the possibility of replacing data from highspeed filming (Qualisys motion capture) with data from Inertial Measurement Units (X-io technologies), when used to run a model of torso and pelvis in OpenSim. Qualisys motion capture data is used as the golden standard to validate the result visually and with Bland-Altman plots.In order to obtain comparable data experiments are conducted where both methods of collecting data are used simultaneously. Data from the IMU's then need to be processed in Matlab before it can be used to run the OpenSim modell. Several Matlab programs rotate the IMU data to a static reference frame, filter and integrate it, then create viritual markers that correspond to Qualisys' optical markers.The conclusion is that using IMU as a method for collecting data can replace Qualisys in some applications, but not in ones that require high precision. However, this paper only begins the examination of IMU's and there are most likely improvements to be made..
Alarmerande eller förväntat? : En studie av hur ett screeningtest kan tolkas ur ett andraspråksperspektiv
AbstractThe purpose of this paper is to investigate to what extent LS ? a standard screening test for dyslexia ?is also relevant for the purpose of finding second language students with dyslexia. Starting with an overview of recent studies in the field, I have analyzed texts from parts of the chosen material. After a brief presentation of the test, I have presented it from a second language point of view. Furthermore, I have analyzed the way in which the test measures phonological awareness, lexical accessibility and correctness in language.
Effekter av rTMS på benämningsförmåga och språkförståelse: en placebokontrollerad studie av åtta personer med afasi
The purpose of this study was to evaluate the effect of bilateral repetitive transcranial magnetic stimulation (rTMS) on language ability in eight participants with aphasia. All participants underwent two periods of treatment and five periods of evaluation. During one treatment period high frequency stimulation was given to the left hemisphere and low frequency stimulation to the right and in one other period placebo stimulation was given. Boston Naming Test and Token Test were used to assess the effects of treatment on naming ability and language comprehension. Results showed that no significant effects were found on group level.

Dämpning av fläktljud i diskmaskin
Detta examensarbete omfattar akustiska undersökningar utav en desinficerande diskmaskin av typ Getinge 8666/8668 och har utförts på Getinge Desinfection AB i Växjö. Vi har undersökt hur man med enkla medel kan sänka ljudtrycksnivån i maskinens närhet. Mätningar har utförts på diskmaskinens torkprogram, där torkfläktarna är de mest dominerande ljudkällorna och ljudet främst är luftburet. En systematisk analysmetod bestående av införandet av successiva dämpningsåtgärder visade att de dominerande ljudvägarna går via taket, golvet samt till viss del spalter i maskinens väggar. Genom att isolera både tak, golv och spalter kunde ljudtrycksnivån sänkas med totalt hela 5,9 dB.
Safire : Unik brandvarnare med smart design för ökad säkerhet
Can you ensure that your smoke detector will sense fire and sound the alarm in the middle of the night?In 80 percent of the cases where emergency pulls out, smoke detectors are missing where the fire occurred. In the year of 2009, 118 people in Sweden died in fires ? most of them would have survived if there had been a functioning smoke detector.Earlier development of smoke detectors has mainly been focusing on components that sense smoke and alert in case of fire. But in most cases the problem has not been whether the smoke detector was working or not as fully assembled, but rather that it was missing.

Gröna tak som del i ett hållbart stadsbyggande
Green roofs have seen a revival in the society of today. They provide many functions
of which both society as a whole and the individual can take part. In particular
extensive green roofs, that requires little or even zero maintenance, provides very
valuable functions. Green roofs affect our environment and our economy in a
positive manner as well as the physical expression of buildings.
In this bachelor thesis the impact of green roofs on society has been examined
throughout literature studies. The result as a compilation of contemporary research
in this field is presented together with a discussion about the use of green roofs in
general.
The two major arguments for an extended use of green roofs are, the high
stormwater retention capacity and the cost-benefits seen over time compared to a
conventional roof.
Gudssyn inom den sufiska poesin : En jämförelse mellan Jalal ad-din Rumi och Fakhr al-din Araqi
The purpose of this essay is to compare the works of Jalal ad-din Rumi and Fakhr al-dinAraqi to see which ideas of God the two writers want to convey. Rumi and Araqi weretwo actors in the mystical dimension of Islam, who lived in the thirteenth century inwhat is today Turkey. Both were of Persian birth and their works were written inPersian.The material I have chosen to work with is Lama´at by Araqi and parts of theMasnavi by Rumi. Both of them have been translated into Swedish by Ashk Dahlén.The theoretical premiss is taken from Influence in art and literature by GöranHermerén. My method is to find images for God in the texts to see which ideas of Godthe two writers want to convey.My review shows that many of the images come from the Koran and speak ofpersonal qualities of God.
Stopptidsanalys i hyvelanläggningen vid VIDA Vislanda
VIDA Vislanda har ett behov av att veta hur effektiv produktionen är på deras nya hyvleri. Därför är arbetets syfte att undersöka stopptidslängder samt bakomliggande orsaker till stoppen på företaget. Det ingår även i arbetet att lämna förslag på åtgärder som kan leda till förbättringar i verksamhetsgrad samt reduktion av stopptid.VIDA Vislanda vill veta vilken verkningsgrad, verklig löpmeter ut och verkligt stycketal ut för varje enskild dimension och längd.

Partnerskap i samförstånd? En studie av den regionala partnerskapsmodellen ur ett intresseperspektiv
In 1998 a new regional development policy was introduced by the Swedish government. A central feature in the policy was the formation of partnerships at the regional level. The partnerships were meant to consist of local and regional stakeholders, representing a great variety of interests, who would collaborate in order to improve regional development. The new policy was promoted, besides being more efficient, as a way to broaden political participation and to break male-dominated structures.This thesis discusses whether the regional partnership actually favours ?women's interests?, in terms of how the relationship of power between women and men is constituted by the model.
Övergång till helkrossballast : En studie för Strängbetongfabrikerna i Veddige och Herrljunga
This exam report has been developed in association with Strangbetong AB, Sweden.The natural gravel that is being used as fine aggregate for concrete production today is an ending natural recourse and the Swedish government has decided to strongly reduce the extraction from the year of 2020. The only reasonable replacement is aggregates from crushed rocks but this material has other properties than natural aggregates. The concrete manufacturers now have to learn how to use these new fine aggregates in a cost effective way in order to ensure the quality of their concrete production.In this project, crushed aggregates and combination of crushed and natural aggregates have been tested with existing formulas for fresh concrete. The two parameters yield stress and plastic viscosity have been measured which gives a good description of the workability of the fresh concrete. Different methods to make measurements on the dry fine aggregates, has also been tested, to find out if there is any correlations between these parameters and the parameters from the measurement on the fresh concrete..
