Facial expressions are a part of our body language that helps us to clarify the verbal communication between humans. We use our facial expressions every day, both consciously and unconsciously, to express emotions and attitudes depending on the situation. The hypothesis of the study is: Given a facial expression, how well can Microsoft Kinect, as an input method, determine a person?s feelings with the two algorithms Naive Bayes and Sequential Minimal Optimization? The feelings are limited to happy, sad, surprised and disgusted. With the help of Kinect, a person?s facial data, both coordinates of the face and parameterized data, were saved and used for machine learning.

Inom disciplinen kognitiv ho?rselvetenskap tilla?mpas en integrerad ansats da?r taluppfattning beskrivs ur ba?de ett auditivt bottom-up-perspektiv och ett kognitivt top-down-perspektiv. Studien underso?kte hur taluppfattning varierar med, respektive utan top-down-sto?d och vad de kognitiva fo?rma?gorna uppma?rksamhet, minne och inhiberingsfo?rma?ga hade fo?r inverkan. Taluppfattningsfo?rma?ga utva?rderades med hja?lp av ett Speech-In-Noise-test (SIN-test) som bestod av tre deltest da?r enstaviga ord presenterades i en ofo?rdelaktig miljo? besta?ende av ro?ster som talande i mun pa? varandra.

Mastitis in dairy cows is an emerging and challenging disease in the tropics, including India. Nation-wide reports suggest that the incidence of clinical mastitis varies from 3.94% to 23.25%, and for subclinical mastitis from 15.78% to 81.60%. In Assam, a northeastern province of India, dairy is an essential part of the mixed farming system that exists in the state, but the milk yield is far below domestic standards. In 2009-2010, International Livestock Research Institute (ILRI) and local associates started to develop a training program for local farmers in Assam, in order to enhance the informal bovine dairy sector in and around Guwahati, India. The project continued until mid-2013.

Syftet med denna studie var att undersöka nyblivna mödrars uppfattning av amningstidens längd och vårdtidens längd relaterat till bakgrundsvariablerna ålder, utbildning och paritet. Datainsamlingen skedde under hösten 2000 och våren 2001. Insamlat material infördes i det statistiska programmet Stat View. Materialet bearbetades därefter i olika statistiska test som t-test, korrelations test och Chi-två test. Resultatet för den exklusiva amningen visar att kvinnor som är högutbildade och omföderskor ammar längre än de lågutbildade och förstföderskor.

Syfte: Syftet med uppsatsen är att undersöka och analysera om det finns något samband mellan företags lönsamhet och dess kapitalstruktur, storlek eller branschtillhörigheten. Detta innebär att en empirisk studie kommer att ske på soliditet, omsättning samt branschtillhörigheten för att se hur och om det finns något samband mellan lönsamheten och dessa tre faktorer. Vidare är syftet även att undersöka om det kan finnas något samband mellan företags lönsamhet och företags standardavvikelse på räntabilitet.Metod: Undersökningen är en empirisk studie med en deduktiv kvantitativ och kvalitativ ansats. Empirin undersöks med olika statistiska metoder såsom regressionsanalys och korrelationsberäkning.Teori: Uppsatsen har utgått från teorier gällande kapitalstruktur och lönsamhet. Nyckeltalen som används från dessa teorier är soliditet respektive räntabilitet på eget kapital.Empiri: Data från de 20 största börsnoterade företagen på Stockholmsbörsen har samlats in från företagens årsredovisningar 2003-2007.

Ett psykologiskt test används främst inom utbildningssammanhang och kliniska sammanhang, men även inom rekrytering, urval och organisationsutveckling. Det finns idag ett flertal personlighets- och begåvningstest som mäter olika aspekter som kan vara relevanta för en organisation. Predicting Job Performance, PJP, som har sin utgångspunkt i femfaktormodellen, är utvecklat av Psykologiförlaget AB och består av två delar som mäter olika dimensioner av personlighet och begåvning. I denna studie har psykometriska beräkningar utförts för att utvärdera instrumentets reliabilitet samt validitet, främst genom test-retest-metoden. Undersökningsdeltagare var 49 psykologistudenter vid Stockholms Universitet.

The aim of this master's thesis is to present an introduction to semiological analysis of web based material, which is a hypothesis that combines the theoretical framework of classical Saussurean semiology, visual social semiotics as was developed by Günther Kress and Theo van Leeuwen, and Roland Barthes's notion of 'Myths'. Furthermore, a new tool called 'pseudo-signifier', constructed solely for the thesis, is also used in conjunction with the semiological analysis. The hypothesis is tested in a case study involving the web portal of a Swedish commune, Gothenburg (goteborg.se). A complete semiological analysis is performed on the case. The case study revealed numerous findings of interest, among others that images and texts on the web portal were sometimes used in a contradicting manner, and often in a way that symbollically excluded citizens from the portal, a fact which could be uncovered when studying underlying myths that permeated the web portal.

The average length of life is increasing in the western world, hence the older population is growing. A common health problem among the elderly is malnutrition. Malnutrition causes decreased body strength and is associated with an amplified risk of infections, depression, fractures and increased mortality. The health care system is therefore faced with the challenge to prevent malnutrition among the growing population of elderly. This could be done by providing nutritious foods developed to meet the specific needs of elderly. The overall objective of this project was to test a healthy energy dense drink based on oats targeted for the elderly consumers as a strategy to prevent malnutrition among elderly.

Vi utför en fallstudie där vi studerar 108 annonseringstillfällen av nyemissioner under åren 1993-2001 på företag listade på Stockholmsbörsen. Vi undersöker om det föreligger någon överavkastning kring annonseringsdagen. Den effekt vi eventuellt observerar används sedan som den beroende variabeln i regressionsmodeller där vi försöker ta fram förklarande variabler. Vi utför kompletterande test såsom t-test och stabilitetstest för att öka reliabiliteten av resultaten..

Military dogs in Sweden spend their first 18 months after weaning with a foster owner that has volunteered to care for its upbringing. The foster owner is advised by a consultant and offered three opportunities to train the dog together with other foster owners. There is a positive correlation between the number of attended training opportunities with the consultant, or other professional dog trainers, and the results of the dog in the temperament test at the end of the 18 months. The test results are in turn positively correlated with the likelihood of the dog to enter service. This thesis aims to investigate why the number of training opportunities is important for the dog?s chance to enter service by identifying foster owner factors that influence the success of the dog and which temperament test items the factors have the strongest impact on.

Many companies today are investing in various computer-based tools to support their planning, decision making or communication processes. However, end users are often reluctant to accept the available information systems, which mean that these investments are extremely risky. Understanding why users choose to accept or reject an information system has proved to be one of the most challenging problems in this research area. Previous studies have focused on users' beliefs and attitudes regarding use intentions, but the results have, however, been both mixed and incomplete. In this study, I have used the Swedish youth? s use intention of mobile banking and a quantitative study was performed based on five different hypotheses derived from previous studies.

All inclusive travel has become a popular way to travel abroad. When tourists pay for everything in advance their need for contact with the local people will be reduced. The consequences of this can be dissatisfaction from the local people as they are left out and do not share the financial benefits created by tourism. During the purchasing cycle of an all inclusive travel, it is possible that the tour operator can influence a sustainable development.The aim of this paper is to compare how a large and a small tour operator in their purchase of all inclusive holidays interacts with local players to create sustainable development, thereby creating a surplus value to the customer. The hypothesis is that the amount of knowledge and application of this knowledge regarding sustainable development differs in the purchase process between large and small tour operators.This paper was carried out as a case study.

Syfte: Syftet med detta examensarbete är att kartlägga förkunskaperna i områdena fotosyntes, biologisk mångfald, växthusgaser, energi och hållbar utveckling, samt evolution och naturligt urval hos gymnasieelever som läser ämnet Biologi 1 på det naturvetenskapliga programmet på en gymnasieskola i västra Götaland. Syftet är också att utvärdera betydelsen av diagnostiska test för dessa elever och deras lärare. Avsikten är även att presentera möjliga förslag till att utnyttja resultaten av dessa test för att på bästa sätt kunna hjälpa de elever som har svårigheter i eller ligger i riskzonen för att ha svårigheter i dessa kunskapsområden i Biologi. Metod och genomförande: Undersökningen har dels genomförts med en diagnostisk test, dels genom intervjuer av tre lärare på gymnasieskolan. Eleverna har även fått två analysfrågor som berörde deras uppfattningar om användandet av denna test inom ämnet Biologi. Resultat: Resultatet visar att eleverna har bristande förkunskaper inom områdena fotosyntes och betydelse av växthusgaser. Både elever och intervjuade lärare är positivt inställda till diagnostisk test i Biologi.

This thesis is concerned with investigating the Roma, a group that is left out in most of the territory bound theories. The theoretical purposes are to develop theories that increase the understanding for the Roma as a diasporic nation without state and the advocacy networks they are organised in. The main empirical purpose has been to study two organisations as cases and how they position themselves against the European Union concerning identity politics. The two organisations are European Roma Rights Centre (ERRC) and Dzeno. They are a part of the same network that works on different levels with the rights of Roma.

Purpose: The purpose of this thesis is to clarify and evaluate the concept of scenario planning.Methodology: Our research methodology has a qualitative approach and uses deductive reasoning. The theoretical field of strategy formulation has been reviewed and in specific the concept scenario planning was unravelled and mapped. Thereafter, our model was tested in a case study where the empirical data was collected through personal interviews. Theoretical field: Literature and articles from the strategic management field have been reviewed with a focus on strategy formulation, scenario planning and Williamson?s theory for the creation of a portfolio for strategic options.Empirical base: Personal interviews and secondary sources such as financial reports, articles mainly from industry media and articles found in the databases ELIN and Affärsdata.Analysis: The analysis work constitutes the testing of our model for scenario planning, integrated into Williamson?s portfolio of strategic options for the future.Result: The work has resulted in a clarified model of scenario planning with links to strategic management schools.
