We study the predictability of sentiment on stock return of the Hong Kong market. We measure sentiment by forming composite sentiment indices from several proxies using principal component analysis and the partial least square method. We find that sentiment measures using either method have similar in-sample forecasting power but the one formed by using partial least square method has better out-o
The aim of this study was to get a deeper understanding of how Unit Heads within the Swedish social services view the work environment of social workers in social welfare offices. The study was based on six social services Unit Heads from the southern part of Sweden. Semi structured interviews were used to examine what different factors affect the social workers in social welfare offices work envi
Medelpensioneringsåldern i Sverige har länge varit mer eller mindre konstant trots att medellivslängden har ökat. Syftet med denna studie är att undersöka huruvida det finns en optimal pensionsålder när den förväntade återstående livslängden är en annan än den Pensionsmyndigheten förutsatt och om detta kan förklara den konstanta medelpensioneringsåldern. Studien tillämpar en kvantitativ metod och
Idag använder sig en majoritet av alla svenska grund- och gymnasieskolor av en lärplattform. En lärplattform är mjukvara som stödjer både det administrativa och pedagogiska arbetet och används bland annat till kommunikation, bedömning och till att tillhandahålla material i undervisningen. Uppsatsen kopplar samman lärares upplevelser av dessa lärplattformar till teorier gällande användaracceptans.
The aim of this study is to investigate the hotel attributes that affect selection by football fans when travelling away from home to participate in a sport event.

Questionnaires were distributed through online c
Knowledge about women’s participation in combat roles, yet alone in national armed forces in the Arab countries is very limited. Although more women are acquiring access to combat roles worldwide, most scholarly investigations have focused on servicewomen in the West. As the United Arab Emirates (UAE) is emerging as a rampant participant in international relations and it contributes forces to glob
Detta examensarbete utfördes i samarbete med LVI, Low Vision International AB för att utveckla ett nytt arbetsplatsanpassat system för personer med nedsatt syn. Företaget är specialiserat på att utveckla, producera och sälja olika typer av tekniska synhjälpmedel i Sverige, Europa och USA. De hjälpmedel som utvecklas på LVI består till största del av förstorande läskameror som finns i olika utföranThis thesis objective was to design a workplace integrated system for people with visual impairment for LVI, Low Vison International. The system is in the same category of video magnifiers as the company’s other products and it was desired from the company that the product maintained the overall LVI design language. Initially a pre-study was performed that consisted of identifying the user, analy
With the use of arms trade data spanning the time period between 1992 and 2010, this thesis sets out to study what influence joining NATO has on a country’s volume of arms export and its probability of exporting arms. An assessment is also made of how NATO members trade arms. The data is estimated with a set of different gravity models and by using linear regressions evaluating volume and logistic
The sediment composition of drumlins in the Åsnen area in Småland, south Sweden is poorly studied. Excavations are being planned with intention to study the internal architecture and composition of these drumlins. As a preliminary investigation this thesis was done to determine the sediment depths in the tail of a drumlin at Rörvik gård, situated on Vemboö in Lake Åsnen. To determine the sediment
Bakgrund: Amyotrofisk Lateralskleros (ALS) är en dödlig neurodegenerativ sjukdom. Destruktion av motorneuron leder till att ALS-patienterna blir helt förlamade, vilket medför en stor påverkan i patienternas liv. Syfte: Belysa patienters upplevelse av att leva med ALS, genom att beskriva hur patienters liv och livskvalitet påverkas av sjukdomen. Metod: Litteraturstudie med integrerad analys. Result

Ectomycorrhizal fungi (EMF) mediate nutrient exchange between trees and soil in coniferous forests. Nitrogen (N) currently limits net primary productivity (NPP) in many terrestrial ecosystems but N deposition may alleviate this limitation, inducing limitation of phosphorous (P) instead. Studies have shown reductions in production of EMF mycelia (EMM) when trees are alleviated limitation of N, unle
The purpose of this study was to examine how personnel working with unaccompanied refugee children at homes for care or residence highlights individualized support in their work, and to analyze opportunities and obstacles within this work. Qualitative interviews were performed with five personnel, from three different homes for care or residence, working with unaccompanied refugee children. The co
Studiens övergripande syfte var att undersöka sambandet mellan anställdas uppfattade organisationskultur och självskattade arbetsengagemang samt psykologiskt kapital, samband med begränsade resultat från tidigare forskning. Uppsatsen ämnar även undersöka vilka kulturtyper som fanns i deltagarnas uppfattade organisationskultur och deras samband till skattningen av arbetsengagemang och psykologiskt
Syftet med den här uppsatsen är att skapa förståelse för medlemmarnas kommunikativa funktioner i ett oetablerat politiskt parti och hur dessa funktioner kan användas i partiets arbete med strategisk kommunikation. Vidare behandlar uppsatsen hur oetablerade partier kan arbeta och ta tillvara på de interna resurserna för att nå sina mål. Uppsatsen grundar sig i en fallstudie av det politiska partiet
Social workers within health care approach to their own profession in multi professional teamwork The purpose of this qualitative study was to examine and illuminate how social workers perceive their own professional role, the professions legitimacy and hierarchical position in interdisciplinary collaboration of multi professional teamwork within the hospital. The empirical research is based on f
Kiselalger, vattenlevande, mikroskopiska organismer med kiselskal, används som bioindikatorer för vattenkvalitet eftersom de är artrika och påverkas av sin omgivning. Processen kallas Kiselalgsmetoden och utförs genom en standard, en standard jag valde att analysera. Proven tas från stenar i vattendrag och sedan görs ett preparat som är fixerat på objektglas som kan undersökas i mikroskop genom aDiatoms, water living, microscopic organisms with silicon shells, are used as bioindicators of water quality because they are diverse and influenced by their surroundings. The process is called The Diatom Method and is accomplished through a standard, a standard I have chosen to analyze. The samples are taken from stones in water streams and then a preparation is made to fix the algae on slides t
There are a number of existing and new biofuels on the Swedish market. These operate differently and need to be managed in different ways. In order to solve problems associated with the transport sector's large and unsustainable energy consumption and emissions of CO2, it is important to study how biofuels can work in practice and gain a broad knowledge of prerequisites for their mainstream ma
Sorgenfrei-Tornquistzonen har sedan slutet av Paleozoikum undergått upprepade deformationsfaser, både extensiva och kompressiva som resulterat i omfattande blockförkastningar och bassänginversion. Detta har skapat en mycket uppsprucken berggrund som med tiden läkts av olika mineral. Denna studie presenterar en inventering av sprickmineralen i Dalby stenbrott i Skåne, var bergartsprover har samlatsThe Sorgenfrei-Tornquist zone has, since the late Paleozoic, undergone repeted periods of deformation, both extensive and compressive which have resulted in comprehensive block faulting and basin inversion. These factors have created a highly fractured bedrock that has healed of various minerals along the tectonic evolution. This study presents an inventory of fracture minerals in Dalby quarry in
