Språkliga förmågor och deras relation till läsförståelse hos barn i 12-årsåldern med lätt till måttlig sensorineural hörselnedsättning - en jämförelsestudie
The aim of this study was to examine language abilities and their correlation to reading comprehension in 12 year old children with mild tomoderate sensorineural hearing impairment. Eight children with mild to moderate hearing impairment were tested in listening comprehension, grammatical comprehension, receptive vocabulary, phonological short termmemory, word finding, semantic relations, reading comprehension, comprehension of written words and decoding of words and non-words. The results were compared to results from a comparison group. The children with hearing impairment had significantly lower results in phonological short term memory and decoding. No significant difference was found between groups in reading comprehension.
Beslutsfattande och uppmärksamhet : Heuristikers påverkan på kognitiva resurser inom konsumentpsykologi
Every day we make numerous decisions. Some are better than others. Intuitive decisions usually results in less good decisions when we do not reason about our choices. Research has been interested about the process that is behind how we make good decisions. Decisions we face every day, such as when we shop, determined using various mental shortcuts that we use unconsciously.
Psykisk ohälsa bland barn och ungdomar i socialtjänstens öppenvård. : En kvantitativ studie om psykisk ohälsa, kön och socioekonomi i Södermalm och Rinkeby-Kista utförd med ?the Strengths and Difficulties Questionnaire?(SDQ)
The aim of this quantitative study is to describe the prevalence of mental health problems within the group of children and adolescents who receive support from two in home care units within the social services of Rinkeby-Kista and Södermalm stadsdelsförvaltning in Stockholm. Another purpose is to examine whether socioeconomic background and/or gender are associated with the prevalence of poor mental health, or mental health problems of a specific kind, in the studied population. Mental health is measured with the SDQ, a behavioral screening questionnaire that is widely used in Sweden and internationally. The study is based on data collected by the two units, which routinely screen children and adolescents with the SDQ. The main results of this study indicate that mental health problems are common in the studied population.
Luftutsläpp från järnmalmsproduktion : - Strategier för systematisk luftkvalitetsmätning
The mining company LKAB extracts iron ore in three areas in the north of Sweden, Kiruna, Malmberget and Svappavaara. The iron ore is refined and in the pelletizing plants the material is rolled to finished pellet product. The different steps of pelletizing plants causes among other things emissions to the air. It occurs occasionally stops in the production and the emissions are vented via an emergency chimney without purification. The aim for this work is to look into how LKAB may improve their monitoring of air emissions and control of ambient air quality and the analysis methods which are suitable for measuring.
Hemodialyspatienters självrapporterande saltvanor
The purpose of the study was to describe hemodialysis patients self-reporting salt habits associated with cooking and food intake. Furthermore, the purpose was to investigate possible differences in inter Dialyze significant weight gain at low and high self-reported salt consumption. The study was an empirical descriptive study of comparative features and consisted of a convenience sample from two hemodialysis units in southern Norrland. Study group consisted of 37 persons who had been ongoing hemodialysis treatment and their age ranged from 42-86 years. A questionnaire was used in two parts and both parts contained 15 foods.
Med framsidan framåt ? En studie av taste-cultures och face-front marketing på två svenska folkbibliotek
The aim of this Master?s thesis is to examine how librarians in two Swedish public libraries view the subject of face-front marketing and literary hierarchy. The questions posed in this thesis are: How do two public libraries in Sweden market fictional literature? Which literature does get marketed? How do the librarians view fictional literature? How do the librarians view marketing? and Does Herbert Gans? literary scale work to examine the marketing of fictional literature in two Swedish public libraries? The theoretical starting-points are Niels Ole Pors? thoughts on stock development, Philip Kotler?s thoughts on the responsible non-profit organisation and Herbert Gans? thoughts on taste-publics and taste-cultures. The empirical material was gathered through qualitative interviews with library staff in two public libraries in the south of Sweden, and by reading a sample of the fictional literature exposed in these libraries.
Karaktärisering av hårdmetallpulvrets råvaror och dess påverkan på pulvrets flödesegenskaper
This thesis has been done at the powder department (GH) at AB Sandvik Coromant in Gimo. With a rheometer measurements has been made on raw materials and powder blends. The focus of this report has been to find correlations between raw material powders and press data, comparisons have also been made between raw materials and powder blends.The rheometer can show information of how a powder act in flow conditions, together with air and with pressure. Analyses has been done comparing the rheometer data with press parameters (for example: rejected orders, weight variations and the compaction pressure) with the goal to find correlations between the powders flow properties and the powders compaction in production.The measurements and analyses have been showing that the powder flow properties depends on the powders composition and that properties like flow rate, aeration and permeability varies between powder blends and batches of the same powder sort. It seems to exist a correlation between the pressure force and the flow rate of a raw material.
Lönsamheten av analytikers riktpris - En studie av svenska bolag handlade på Stockholmsbörsen
We acknowledge the lack of empirical studies of the performance of analyst target prices in the Swedish stock market by examining the profitability of target prices for stocks publicly traded on the Stockholm Stock Exchange. We use consensus target prices issued between 2006-2010 and create two different strategies to observe the abnormal returns generated during this period. Going long in the top decile stocks with the best target prices and going short in the bottom decile stocks with the worst target prices generates a statistically significant abnormal buy-and-hold return of 8.9%. An active strategy with daily portfolio rebalancing and a timely response to target price changes generates a less significant monthly alpha of 1.4% against CAPM. The results show to be robust against the size effect discovered by Fama and French.
Bankers identifieringsmetoder : Nu och i framtiden
Keywords: ID-method, internet, security, digitzing, bank Background: The digitizing of our society continues to grow and more parts of our lives is spent on the internet. The banks are one of the institutions that is at the forefront of this development since they established themselves on a early basis. The banks meeting points have since this establishment moved from the regular bank office out on the internet. A problem that has occurred during this transfer is the possibility to positive ID a customer in a virtual world. It is essential to offer the customer methods to identify themselves that are both safe and easy to use.
Lyviken : -bedömning av dagvattenkvalitet
AbstractStormwater is defined as rain- and melted water. Ludvika kommun had little knowledgde about the stormwater that reaches a specific recipient Lyviken. Therefore they intended to do an research of the stormwater that leads down to Lyviken. The aim with this study was to assess the quality of the contents in the stormwater based on pH, conductivity, phosphorous, nitrogen, bacterias, oil and one sample that meassured the value of several methals. Since the population has increased for decades, the area of hard surfaces and asphalts areas also has increased. This can increase the pollutions that finally ends up in the recipient.

Starka varumärken, starka finanser?: En studie av skillnaden i lönsamhet mellan starka och svaga varumärken
It is a common view that companies should focus on building brands to increase profitability and stabilize cash flows. However, building and keeping brands alive is costly. Many firms spend large sums on branding only because they are supposed to, without knowing if they will actually gain from it. Up to date, there is limited convincing evidence that branding actually contributes to shareholder value creation. This thesis aims to investigate the relationship between brand strength and profitability and shareholder value.
Ledarskapsskillnader mellan ofentligt och privat anställda ledare : När sektorstillhörighet inte längre är relevant
The Public vs. private movement has over the past decades identified numerous significant differences between public and private organizations. The observed differences covers almost every field in administrative economics ranging from organizational structure, management accounting, goal-setting and in the past few years even leadership. Strangely, in the majority of these studies little or no regards are given to organizational characteristics or fundamental differences between compared organizations and if these organizations really are comparable when studying the effect of sector.The aim of this study is to compare leadership in relatively similar organizations from both the public and private sector and so clarify if earlier identified differences in leadership styles still surface when leaders working with approximately the same thing in a similar work context are studied.A sample of 348 Swedish principals was drawn from both municipal and private elementary schools. The respondents answered a web-based survey based on the CPE-model resulting in leadership styles mapped according to three orientations: change, production and employee.
Vätskebehandling inom brännskadevård
SummaryPatients with burn injuries involving more than 20 percent of the total body surface area lose a lot of fluid and are in the risk of developing a severe hypovolemia. Fluid resuscitation is a corner stone in burn care and is important for preventingfurthercomplications. The most common resuscitation formula is the Parkland Formula. Hourly urine output is a measure used to evaluate if the fluid given is sufficient enough to maintain a sustainable tissue perfusion. Inhalation injury, abuse of alcohol and drugs are some of the factors that may increase the amountoffluid needed.
