This paper describes a study examining four different GARCH models AR(1)-GARCH(1,1), AR(1)-EGARCH(1,1), AR(1)-APGARCH(1,1) and AR(1)-GJR-GARCH(1,1), and their ability to predict future volatility and thereby providing more reliable estimates for Value-at-Risk. The study is based on daily observations for the return of the OMX Stockholm 30 Index, during the time period 31st December 1996 to 29th De

Preventing creaming or sedimentation by the addition of thickeners is an important industrial challenge. We study the effect of the addition of a "free" nonadsorbing polymer (xanthan gum) on the stability against creaming of sterically stabilized O/W emulsions. Therefore, we analyze our samples using microscopy and rheological measurements. At low xanthan concentrations, the emulsions cream. Howev
The role of peripheral arterial disease in ulcerated diabetic feet has long been underestimated. Progressive claudication, rest pain and the extent of irreversible tissue loss have frequently been indications for revascularization for neuroischaemic ulcers in diabetic patients. These typical ischaemic symptoms are warning signs that are less frequent in diabetic individuals with ischaemia than tho

Abstract in French La mutilation génitale féminine (MGF) ou bien le terme neutre de plus de valeur, l'excision génitale féminine (EGF) est pratiquée un peu partout au Soudan, où environ 90% des femmes subissent le type le plus coûteux de l'infibulation, l'EGF. Une nouvelle approche pour combattre l'EGF au Soudan consiste à reconnaître l'ancienne forme cachée de l'EGF, la reinfibulation après l'accFemale Genital Mutilation (FGM) or the more value neutral term, Female Genital Cutting (FGC) is widely practised in northern Sudan, where around 90% of women undergo the most extensive form of FGC, infibulation. One new approach to combating FGC in Sudan is to acknowledge the previously hidden form of FGC, reinfibulation (RI) after delivery, when the woman is sewn back so much as to mimic virginit
European air traffic control is undergoing changes in organization and technology in order to increase efficiency in air traffic. Change processes can have a negative impact on existing safety cultures, the foundations of safety work, and on safety. This paper reports on an assessment of safety culture at one administrative and two operative units in a Swedish air traffic control setting, using qu
Popular Abstract in Swedish "Det var en gång en kung som aldrig gjorde något bra för sina undersåtar. Han gjorde faktiskt aldrig nånting. Det enda han ville var att äta och dricka, och berusa sig tillsammans med sitt hov. Under tiden svalt folket ihjäl." Anna frågar: varför kunde inte människorna äta hemma? "Tyst nu, och lyssna på fortsättningen…" (citat ur avhandlingen) Martina Camparts forskniAbstract The point of departure for this study is the author's experience as educator in a residential home for children (age 6-14) with social-emotional problems, in Italy, between 1980 and 1989. One important element of the pedagogical approach was the use of narratives (personal, of others, of fiction) to prompt children's interest/ motivation to reflect about issues of personal concern.

Syftet med studien är att undersöka vilken roll takt och rytm spelar i en idrottslärares undervisning. För att förtydliga uppsatsens syfte och beskriva idrottslärarnas uppfattning behandlas följande forskningsfrågor: Hur ser idrottslärare på takt och rytm i sin undervisning? Vad uppfattar idrottslärare att det är de ska undervisa i när det gäller takt och rytm enligt kursplanen? Hur ser idrottslärMeasure and rhythm: What part do concepts of measure and rhythm play in a physical education teachers way of teaching? The purpose of this study is to determine what part the measure and rhythm plays in a physical education teacher's way of teaching. To clarify the purpose of this study and describe physical education teachers' perception, the following research questions are processed: Ho
The aim of this study was to identify what possibilities three lecturers, called Change Agents, have to implement the concepts from the training programme “Child Rights, Classroom and School Management” at Makerere University.

Background: More than half of all new HIV infections in sub-Saharan African countries, including Uganda, occur among young people between the ages of 15 and 24, the most sexually active period of their lives. Understanding the contextual determinants of sexual behavior in this group is crucial in combating the pandemic. Aim: The overall aim of this study was to assess the impact of demographic, r
Aims: A diabetic foot ulcer (DFU) is associated with increased cardiovascular risk and mortality, independently of ulcer etiology (ischemic, neuro-ischemic or neuropathic). Ankle–brachial index (ABI) is the most commonly used test when diagnosing peripheral macrovascular disease and is a well-known marker for increased cardiovascular risk. Transcutaneous oxygen pressure (TcPO2) is considered to be

A polymer electrolyte fuel cell (PEFC) is an electrochemical device that converts chemical energy into electrical energy and heat. The energy conversion is simple; however, the multiphysics phenomena involved in the energy conversion process must be analyzed in detail. The gas diffusion layer (GDL) provides a diffusion media for reactant gases and gives mechanical support to the fuel cell. It is a
