Passive acoustic diver detection

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

The Determinants and Impacts of Executive Stock Options

The thesis main objective is to establish the determinants for granting executive stock options and to examine their impact on performance for firms listed on OMXS30. The analysis is based on accounting data gathered from annual reports and Thomson Datastream. The empirical results display that firms grant stock options to mitigate the principal-agent problem. Furthermore, risk proves to be positively significant with executive stock options, implying that either executives increase the level of risk after being granted stock options or influence the decision of the remuneration towards stock options when the firm increase the level of risk, in purpose to boost the expected value of their options. No relation between executive stock options and firm performance could be established..

Jag var rädd för att lämna honom

This case-study examines the correlation between young men and democratic instability in group discussions with two analyzing methods in one. One part of the method used is deliberative democracy which aims to explain how democracy works within the frames of discussion in ordinary citizens groups. In this study the citizens is upper level secondary school students. The other part of the method used is the theory pulled by many scholars lately, the demographic impact on democracy. With these two combined in one this study compare the theory of young men as more active in political violence and as a destabilising factor of democracy on country-level with the results of the study in deliberative democracy in small group discussions.

Ett levande klassrum : Undersökningar kring hur reenactment och historiska lekar kan implementeras i historieundervisning på högstadiet

In today?s history teaching in Sweden, role-play and historical re-enactment receive littleattention.

My theses is that this could be done bypresenting new ways of teaching and at the same time find a way to make more studentsinterested in history. The main aim is to investigate if there are ways to offer students anexperience of history by carrying out different interactive exercises with a touch of roleplayand historical recreation.

Försäljning under ansvar; en kvantitativ studie om hur skrämselpropaganda i butiksmiljö kan påverka kunders attityd

Warning-labels as a mean of communicating social responsibility in the store. Previous studies have shown conflicting results regarding the effectiveness of warnings-labels as a way of communicating health hazards to customers and making them more conscious about the risks and changing their behavioural intentions. The focus of this study is to shed some light on how the customers react to warning-labels with different levels of fear in the store atmosphere. The results of this study tells us that liking of the retailer and its image as being socially responsible is not enhanced by the usage of a warning-label. If the retailer decides to use a warning-label, in spite of this fact, the recommendation is to use a high level of fear if the purpose is to make the category seem more risky and make the customers want to change their behaviour.

Hållbar utveckling- En textanalys av miljöpolicy i lokal och nationell kontext

Sustainable development is a concept that has been interpreted in a multitude of ways in different contexts. This essay argues that the discourse of "ecological modernization" has strongly influenced the way in which the concept of ?sustainability? has been constructed in Swedish environmental policy. This interpretation of the concept of sustainability offers the possibility of combining economic growth with ecological sustainability which stands in contrast to the assumptions of Deep Ecology and Green Theory. The aim of this essay is to explore how the concept of sustainability is being formulated in environmental policy both on a national level and in the city of Malmö.Considering these issues in a specific context, this essay focuses on city planning that is as an important instrument to promote urban sustainability both on national and local levels.

Analysmetod för Level Design i enspelarläge : En studie av tempoväxling av Half-life 2 serien samt implementation av resultatet i ett eget verk

Denna rapport behandlar en analysmodell som använts för att analysera Half Life 2-seriens level design. Utifrån denna analys av Half Life 2-serien skapades sedan ett verk baserat på de data som samlats in. Verket kallas Project 25. Målet med Project 25 var att skapa en spelupplevelse som level designmässigt är så lik den kommersiella spelserien Half-Life 2 (Valve Corporation, 2004), Half-Life 2 Episode 1 (Valve Corporation, 2006) och Half-Life 2 Episode 2 (Valve Corporation, 2007) att en spelare inte skulle kunna uppleva någon skillnad i kvalité.Denna rapport är indelad i tre delmoment. Först gjordes en förundersökning där tempoväxlingen i Half Life 2-serien analyserades, sedan skapades själva verket och slutligen utfördes en kvantitativ enkätundersökning i syfte att försöka verifiera om verket uppfyllt sitt mål eller inte.

Svårklassryttares förberedelser för dressyrträning : för bäst lärande

SUMMARYThere was no previous study in what high level dressage riders had for ideas of how to best prepare for their training sessions with an instructor. Neither any study of how high level dressage riders seemed to be more or less susceptible to the instructions from their instructor during their training sessions. If the sport had more knowledge about this, it might result in more riders on a higher level. The purpose of this study was to find out how high level dressage riders are preparing themselves for the best result for an instructor led training session and how they could bring as much as possible instructions from the coach. The two questions of the study were: How are high level dressage riders preparing themselves for a training session with an instructor, practically and mentally, and how can they affect their susceptibility to instructions?The study was carried out both by reviewing existing literature and studies in general education and pedagogy in the riding education, and by a qualitative interview study of six dressage riders who rode on a difficult level at the competitions, during the year of 2009.

Medverkan och inflytande : om brukarnas roll i socialtjänstens kunskapsutveckling

The main purpose of this essay was to study the program "Nationellt stöd för kunskapsutveckling inom socialtjänsten" ("National support for knowledge development within the social services") from the National Board of Health and Welfare on the basis of how such a development, as represented by the program, could affect clients' possibilities to participation and influence within the social services.To respond to the purpose I used the following questions at issue:* How is client participation and client influence defined in the program?* What arguments for and/or against client participation and client influence are stated?* Which patterns and similarities/differences are possible to discern between the municipalities and universities that participated in the program when it comes to client participation and client influence?The study was conducted as a document analysis. I studied documents from the program both on a national and a local level. The essay uses empowerment theories and theories concerning client participation and client influence. The main conclusions were that on the national level the authors of the documents spoke with caution about their view on client participation and client influence and expressed that it had to be balanced against the rights of the citizens and the social workers for example.
