Påverkas röstkällans egenskaper av förändrad stående kroppshållning? En experimentell studie av otränade mansröster
The aim of this study was to investigate whether a direct shift inpostural alignment results in changes in voice source characteristics. Ninemales with untrained voices were recorded standing in ideal posturalalignment and in the deviant postures swayback and kyphosis characterizedby extended hips and a slump back respectively. The voice source wasderived from the audio signal by inverse filtering. The parameters pulseamplitude, maximal flow declination rate, level difference between the firstand second voice source partials, closed quotient and the normalizedamplitude quotient in relation to subglottal pressure were compared betweenideal postural alignment and swayback and kyphosis respectively. Resultsindicate an impact of changed postural alignment on the voice source.Swayback posture gave significantly less pulse amplitude and maximal flowdeclination rate and significantly higher subglottal pressures thus resulting ina less effective phonation.
Kameraövervakning och deliberativ demokrati - En normativ studie av dagens kameraövervakning utifrån teorier om panopticon, den andre och det kommunikativa handlandet
The main aim of this thesis is to introduce a normative perspective to surveillance studies. I examine how the use of videocameras or CCTV-systems can create a social sorting and, then, try to answer why it ought to be reconstructed based on a normative study.For the empirical analysis I use Foucaults theory about the panopticon, maintained by the psychological subjection of the common citizen in the modern world, together with Lianos theory of a more socio-cultural surveillance in the post-modern world. The empirical examination is, furthermore, guided by a theory that describes the construction of the stranger, which today, is not explicitly excluded, because everyone is a stranger in some way, but rather depicted as the other due to institutionalization.The post-modern society today can no longer be built upon a common or divine moral or norm. Thus, I have chosen a normative method, using a deliberative democracy derived from Habermas, focusing on the communicative practice, that can engage and include every citizen in a democratic process. This is necessary for both deciding whether videocameras should be installed and whom and why some should be under surveillance ? to avoid a social sorting that both can constitute and undermine social trust and increase the gap between the governing and the governed..
Helgar målet alltid medlen? En etisk analys av de ekonomiska sanktionerna mot Sydafrika och Haiti och dess humanitära konsekvenser.
In this bachelor thesis my main purpose is to examine the ethical legitimacy of economic sanctions, by assessing the humanitarian consequences this type of actions create. I will do this by a closer examination of the two historic cases of South Africa and Haiti. The humanitarian consequences will then be measured against my chosen theories, to help answer my main questions. The theories I have been working with is the broader interpretation of the just-war theory; the just-sanctions theory, and two major metaethical theories.The result I found after the finished examination of the chosen cases, are that economic sanctions and morality doesn?t necessarily match.
Tala är silver, tiga är guld En studie om förhandlingsprocessen mellan offentliga och privata parter i Danmarks första Public-Private Partnership
The purpose of this thesis is to describe and to increase the understanding of the negotiation process between the public- and the private sector in a Public-Private Partnership (PPP). I have chosen to explore the first ?real? PPP project in Denmark, the construction of Vildbjerg compulsory school in the municipality of Trehøje.This case study is based upon a qualitative method consisting of interviews with the leading negotiators from both sectors. Two different theoretical perspectives are used to construct the basis of the analysis - The Theory of Public-Private Partnership and Negotiation theory - and serve as a concept instrument.The result of the analysis indicates that the negotiators from the different sectors have problems to get out of their traditional roles as purchaser and contractor ? in PPP they should act like partners.
Att marknadsföra ett bibliotek på Facebook
With the advent of a range of social networks, librarians all over the world have startedto ask themselves how this new technology can be used as a way to market theirlibraries. Today's information websites and search engines are difficult competitors forlibraries and information centers, and are forcing traditional information institutions tomarket themselves in new ways.Marketing theories have traditionally concerned themselves with money transactionsand marketing of specific services and/or products. Relationship marketing theories, onthe other hand, focus more on the relationship between the customer and the companythat produces the product or service. These two parties are seen as co-producers, andrelationship marketing theories tend to focus more on a win-win situation, than on thecompany gaining power of the customer. The relationship is the important thing, and thetheories concentrate to a great extent on how to nourish these relationships.This paper is a discussion about whether Facebook as a social network is a usable toolfor library marketing.
Strejkens röster : En kvantitativ studie av mediernas bevakning av Pappers strejk 2010
The writer has attempted to discuss the distinction between the necessary and the contingent. It begins with a criticism against the possibility for a so-called ?a possible worlds realism? to give a ?philosophical explanation? of this distinction. The writer argues that this is impossible, since it requires that a notion of this distinction be already accepted (more precisely that the necessity of such a theory is already accepted).After this specific criticism, the writer intends to show that this is a more general problem that follows any explanation of the contingent/necessary distinction.The writer then discusses the counter-argument that the requirements placed on these explanations are set to high, therefore the writer shows in theory the problem can be solved and sketches a more specific way how to explain and show the basis for this distinction..
Från studier till arbete
Detta examensarbete handlar om övergångsprocessen från studier till arbetsliv för studie- och yrkesvägledare. Syftet med examensarbetet är att undersöka hur nyutexaminerade studie- och yrkesvägledares övergångsprocess från studier till arbetsliv och etablering har upplevts. För att uppnå vårt syfte och för att få svar på våra frågeställningar intervjuade vi yrkesverksamma studie- och yrkesvägledare, arbetsgivare av studie- och yrkesvägledare och sistaårsstudenter på studie- och yrkesvägledarprogrammet. Den tidigare forskning inom ämnet som vi tagit del av har i huvudsak resultatet att övergångsprocessen kan vara en utmaning. Detta eftersom det finns ett kunskapsglapp mellan de kunskaper utbildning ger och det arbetsgivarna kräver.

Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem
This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).
Militära berättelser : Berättande som kulturell praktik i det militära
The main purpose of this study is to show how narrative can be understood as cultural practice, how it can be said to function both internally and externally, and to ask questions about how the narrating subject, through the organizing of narrative, positions it self and mediates between the different discoursive contexts of which it is a part. This is done by an analisys of how six swedish soldiers tells the tale of how they came to choose a military carrer and why they have served or want to serve in peace-keeping missions abroad. The source material is primarily collected through unstructured interviews with theese soldiers, but also through textual analysis of a soldier blog. Theoretically the study draws on a combination of the discourse theory of Michel Foucault, narrative theory, Richard Jenkins theory of the internal-external dialectic of identifikation and intersectionality to construct a framework that allows the narratives to be deconstructed and understood as discoursive products of both the military contexts as such and the larger cultrual context that surrounds it. The conclusions of this study suggests that the organizing of soldier narratives are a complex and multifaceted process, in which the soliders must balance between the ideals, values and norms of the military context while also taking into account how society at large views and interprets the practices and forms of military life.
Att rättfärdiga ?kriget mot terrorismen?: en komparativ
studie av amerikansk propaganda, the Just War Theory och
folkrätten
Terroristattackerna mot USA i september 2001 blev startskottet för USA:s krig mot terrorismen. I detta krig kom Afghanistan att utgöra det första slagfältet. Detta trots att USA ansåg att de ansvariga bakom dåden var terroristnätverket al-Qaida. USA försökte med olika medel rättfärdiga ett krig som skulle föras mot en organisation men i en stat, vilkens regim misstänktes härbärgera de skyldiga. Uppsatsens syfte är således att undersöka hur denna nya typ av krig rättfärdigas.
"Din gud är fejk, dra åt helvete!" : Om elevers syn på religionskunskapsämnet och dess inverkan på förståelse och tolerans
This thesis focus on the presentation of the filmic room the viewer sees in George A. Romero´s three horror classics Night, Dawn and Day of the Dead. The hypothesis goes as follow; fear and element of tension becomes greater if the audience/viewer has a good knowledge about the filmic room in the film, in other words, a good spatial awareness. The conclusion is that it does. The environment is active in its becoming and in its presentation to the viewer.
Mellan Nouakchott och Antananarivo : Afrika och demokratin
The purpose of this essay is on the one hand to study Sub-Saharan Africa from a comparative perspective to analyze different explanations to democratization and on the other hand to compare the democratization of the most interesting cases found. To fulfil the purpose, the essay is divided into a quantitative and a qualitative part. The quantitative part starts from four different theories of democratization and thus has a deductive theory testing approach. We intend to use four theories: the modernization theory, the theory of stable institutions as a prerequisite for democratization, political culture and ethnic diversity as an obstacle for democratization, to test how they correspond with the democratic situation in Africa, and at the same time find deviant cases. The second part of the study takes its start from an inductive perspective and examines institutions and citizens of the deviant cases.
Rein tension measures as indicator of horse - rider communication
The purpose of this study was to gather knowledge about the functioning of the rein tension meter and test it for future studies of match and mismatch between rider and horse. We looked specifically into the possibilities to use a rein-tension meter to determine the quality of cooperation between horse and rider. We examined whether a rider shows a specific tension pattern and also if certain patterns could be recognised for a specific horse. During the study, a manual with pictures and text was written to support the practical use of the meter. The manual describes in a simple way the first steps in the installation and use of the meter.
Elev, lintott eller bara barn? Synen på barn i tre kulturpublikationer ? en diskursanalys
The aim of this Master's thesis is to examine and analyze what discourses about children that can be found in three Swedish culture publications, and also to identify the different social roles that are attributed to children in these publications. The theoretical and methodological background is discourse theory, as described by Ernesto Laclau and Chantal Mouffe. Additional theory used is social constructionism and Norman Fairclough?s critical discourse theory. Three questions are asked: What discourse/s can be found in these publications? What do these discourses tell us about the view on children within the library domain? What social roles are attributed to the children in the texts and what consequences do these have for the power configuration between children and adults? Furthermore there is a discussion concerning what effects these discourses might have on the direct and indirect reception of children in the library.
