Perceptuell bedömning av barns avvikande klusilproduktion : Hur tolkas klusilord med avvikande voice onset time av vuxna naiva lyssnare?

Voice onset time, VOT, är en akustisk tidsparameter som anses återspegla talmotorisk kontroll. VOT är den mest pålitliga akustiska parametern för att särskilja tonande och tonlösa klusiler. I tidigare studier har VOT-värden för svenska barn uppmätts. Det har visat sig att barn med fonologisk språkstörning har avvikande VOT jämfört med typiskt utvecklade barn. Dock saknas undersökningar av hur lyssnare tolkar klusilord med avvikande VOT.

Förebyggande effekter av fysisk aktivitet på depression : ? en litteraturstudie

Objective: To study the evidence on physical activity (PA) as an effective preventive strategy for depression.Methods: A search of electronic databases was performed for articles between 2007 and 2012, both original research and review articles, concerning the link between PA and depression on children, youth and adults. Three reviews, five longitudinal and two cross sectional studies were included.Results:  PA reduced the likelihood of depression in many studies and a sedentary or inactive lifestyle increased the risks for mental health symptoms such as depression. One study showed that low PA in childhood increased the odds of depression as an adult and other studies on teenagers saw a connection and mediation between PA and self-esteem whereas physical fitness showed no mediating effect. Many of the studies and reviews point out the insecurity regarding the dose-response association and the difficulties in defining causality.Conclusion: PA might have a preventive effect on depression. Some evidence exist to support that PA in childhood prevents depression in adults.

Investeringsbeslut för energieffektivisering i monarken

The purpose of this essay is to describe how Boverkets Byggregler has affected the cost ofnewly built houses from 2003 to 2012, to Boverkets Vision 2025. The purpose is also to findagent-principal relations in the construction sector.When investing in an energy efficient house the operating costs are reduced compared to aconventional house. But due to the lower operating costs, the investment cost rises. In thisstudy, we find out if it is economically viable to invest in an energy efficient house comparedto a conventional house from the customer's perspective.The study's approach has been qualitatively where we in collaboration with Derome Hus hadaccess to three conventional reference houses and a passive house and data that was necessaryto conduct viability assessments on houses. We conducted five interviews with people fromDeromekoncernen and Varbergs kommun.The calculation methods we have used in this study are present value method, annuity methodand a sensitivity analysis.

Vad hände med beslutet Gröna Skolgårdar?

The purpose of this paper has been to follow how a decision made has developed within anorganization. We have intended to find underlying causes for the development in order to contribute to the understanding of the lifecycle of decisions.The decision we have chosen is Gröna Skolgårdar (Green School Yards) within the city of Västerås. This project has aimed to make the school yards in Västerås more green, more beautiful and more useful for teaching.We have used Grounded Theory Method as our foundation, complemented with decisionmaking theory.The work with this paper has led to the conclusion that Gröna Skolgårdar changed over time, and did not turn out as first intended. This has had several couses such as how resources wasdistributed, political changes, and different views of the project.We have learned that over time a decision can take unexpected paths, and we have contributed with an example of how this can happen..

Kvinnors känsla av sammanhang och upplevelsen av bröstcancer

Cancer is one of the most common diseases and it affects not only adults but also many adolecents and children every year. Those who are affected of disease face many challenges that will affect their lives. The aim of this literature review was to illuminate adolecents experience of cancer and how it affects them in their daily living. The result showed that the adolecents experience many physical and mental side-effects from disease and treatment. They expressed the need of information, support and understanding from their families, friends, school and care givers.

Tidssynkroniserade mätningar i vattenkraftstationer

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

Sverigedemokraterna - isolerade eller påverkande?

This essay examines the indirect effects of the local strength of the Swedish Democrats on refugee acceptance in the Swedish municipalities. With statistical methods this essay has aimed to investigate if such effects exist and by using statistical data from three periods of time - 2002, 2006 and 2010 ? the investigation has been able to measure effects over time. Based on former research and reasonable expectations the hypothesis for the essay claims that the Swedish Democrats has got an indirect effect upon the refugee acceptance. With the statistical analyses made, the essay is able to conclude that the strength of the Swedish Democrats in municipality elections as well as the change of this strength between the elections does have a negative effect upon refugee acceptance in the Swedish municipalities.

Prehospital vätskebehandling vid stort trauma ur en sjuksköterskas perspektiv : En systematisk litteraturstudie

The aim of this study was to determine which type of fluid to use in trauma care to improve patient survival. The method used was a systematic review, where a total of 18 studies were reviewed and 13 included in the results. The inclusion criteria used in this study were Randomized controlled trial, or studies relevant for the purpose, written in English and published during the last ten years. The studies were identified in the PubMed data base. The results showed that in trauma with hypovolaemia, colloid infusion has a better effect than infusion of crystalloid fluid on blood pressure and colloid infusion reduced the body's cascade systems in a beneficial way. Colloid infusion administered to head injury patients lowered their intracranial pressure more than crystalloid infusion.

Synen på kristendom en analys av läromedel i religionskunskap

The purpose of this thesis is to analyze the perception of Christianity in nine textbooks andidentify changes in-between them and over time. The content of the textbooks will also bediscussed in relation to the steering documents connected to each book.I have chosen to focus on three curriculums, Lgy 70, Lpf 94 and Gy 11. My researchquestions are: how Christianity is treated in textbooks in religious studies in relation to theperception of Jesus, God and man? What are the differences/similarities across time andlearning materials? In what way does the textbooks change with the syllabuses?Text consumption and discursive practices is analyzed with the help of a set of tools thatare based on the critical discourse analysis and Fairclough's three-dimensional model. Theimage of Jesus, if described by a textbook, is also analysed.Three textbooks were chosen from each curricula.

Idrottsämnet och ämnessamverkan : Idrottslärares attityder och förutsättningar till ämnessamverkan

Our interest about interdisciplinary teaching has grown during our time at Högskolan Dalarna and especially during the subject physical education. It became clear that people learn in different ways. The theoretical education in school benefits the visual and auditory strong learners but the kinesthetic strong learners find it more difficult to absorb the information. We argue that integrating subjects is a good way to mix theory and practice and thus gives more students an opportunity to learn the content of the subject. The intention of this examination paper is to investigate the relationship between the attitudes of the teachers regarding interdisciplinary teaching, the practical restrains, possibilities and the presence of interdisciplinary teaching at three different schools.

Civil-militära relationer i komplexa fredsinsatser ? ett organisationsperspektiv

The response to many on-going or emerging conflicts since the beginning of the 21st century has been different forms of multinational complex peace operations. Civil-military relations are a commonly studied field that traditionally has its focus on nations. This study intends, in the context of organisations, to test the correlation between a civil-military approach and outcome in complex peace operations. A hypothesis has been deduced from researcher Robert Egnell?s theory on complex peace operations, that states that: UN peace operations with an integrated civil-military approach are more successful in achieving their goals than peace operations with a divided approach.

Byggprojektstyrning med Earned Value Management

AbstractToday, too many construction projects are delayed and deviates from the budget. Agood project management is the basis for successful construction project. The mostcommon planning methods in the construction industry is currently Gantt chart andCPM. The problem with these is that focus is only at the time of the project anddoesn?t handle the budget.

Productivity of integrated harvesting of pulpwood and energy wood in first commercial thinnings

The aim of this study was to quantify the productivity and the costs of different harvesting systems (teams), containing harvesters equipped with accumulating harvester heads and forwarders, in first commercial thinnings were an integrated harvest of pulpwood and energy wood were performed. In the beginning the plan was to study and measure 20 sites before and after harvest. Due to storms during the summer of 2010, complete data could only be obtained from 8 of these 20 sites. Seven of these sites were privately owned and one was owned by UPM, all of the sites had been pre-commercially thinned. The mean stem density before harvest was 2578 stems per ha and the mean stem volume was 0.074 m3solid over bark.On average 1518 stems/ha was harvested.

Hur påverkas VD : ns belöningssystem av ägandet? ? en studie av svenska noterade bolag

There is a strong debate in the media about the CEO compensation in the listed companies and whether they deserve their high rewards. Many previous studies have shown differences in the reward system depending on the ownership structure, mostly testing for only ownership concentration or ownership category. This study aims to investigate how the influence of the owners affects the CEO reward system, testing for both the level and the structure of the reward. The sample used in the investigation is Swedish listed corporations and consists of 251 observations. A survey was also conducted but due to low response rate and because the answers are not representative for the whole sample the survey will only be used as an illustration.

Gulliver Simulation - En systemarkitektur f or n atverkssimulering av

Nowadays, a lot of resources are spent on developing systems that will make it possible forvehicles to act autonomously, and make them more effective. One of the projects that isworking on this is the Gulliver Project. Gulliver has constructed a number of miniaturevehicles equipped with various sensors, to use as a physical testbed for autonomousdriving. One big disadvantage with this method is the long iteration time that occursduring the development and testing of a new software.This project has improved this process by developing a system architecture of a virtualtestbed where it is possible to simulate autonomus vehicles that communicates throughany type of wireless network. The testbed has made it possible to simulate autonomusvehicle systems that with a reasonable margin of error, acts like the system would actin a physical test.
