Online Social Networks - How are online social networks experienced by individuals in an organizational context?

Organizations’ external environment is full of business ventures. Individuals play ‘in role’ and ‘extra role’ at the same time within the organizations. They are also located in an online environment where they participate and communicate using online social tools. Moreover, individuals within organizations seldom know who are likely to provide the right information or knowledge. The "who kno

Feminisation of the Swedish bank sector 1910-1939 - what and why?

The aim of this thesis is to uncover the determining factors behind the feminisation of the Swedish bank sector 1910-1939, through analysis of time-series and the Union periodical Bankvärlden. Economic and institutional explanations are tried, from a structural-analytical and gender perspective. The results show that feminisation was most rapid during the 1910’s, driven by a strong demand for labo

Ickeparametrisk värdering av optioner

Vi undersöker den ickeparametriska optionsprissättningsmodellen med namnet kanonisk värdering. Vi visar att den kanoniska modellen fungerar väl på svensk data. Vi visar också att kanonisk värdering kan generera ett volatilitetsleende som stämmer överens med det vi observerar på marknaden. Dessa empiriska resultat är konsistenta med tidigare forskning. Ett teoretiskt motiverat resultat är att den k

Malas Aguas en Buenos Aires - En studie av ojämlikhetsfällan och privatiseringen av vattendistributionen i Buenos Aires

Sammanfattning Denna uppsats utreder sambandet mellan privatiseringsreform av vattendistribution och det teoretiska begreppet ojämlikhetsfällan. En ojämlikhetsfälla är ett tillstånd av relativ brist på tillgångar och möjligheter, skapat och bevarat av en snedvriden institutionell miljö. Vår frågeställning är huruvida ojämlikhetsfällan som fenomen består efter en genomgripande privatiseringsreform.

Trust in virtual communities

The way we see computers is changing nowadays. Computers are being seen not only as a utility, but also as a means and mediums of communication. With the proliferation of virtual communities and various social networks, the problem of trust becomes significant. Trust in virtual settings has been mostly researched from a security perspective; however, when it comes to virtual communities sociologic

An orthonauplius of 'Orsten'-type preservation from the upper Cambrian (Furongian) of South China

A tiny larva of ʻOrstenʼ-type of three-dimensional preservation has been recovered from the Upper Cambrian Bitiao Formation of Wangcun section, western Hunan, South China, herein in- terpreted as an orthonauplius stage of a crown-group crustacean. The specimen comprises an ovoid body with a prominent labrum and three pairs of appendages. In all it exhibits comparable morpho- logical similarities w

Experimental and kinetic modelling investigation on NO, CO and NH3 emissions from NH3/CH4/air premixed flames

Ammonia (NH3) is regarded as one of the most viable alternatives to produce carbon-free energy. However, its low flammability and high NOx emissions associated with its combustion inhibit the implementation of pure NH3 as a fuel. Dual-fuel approaches with NH3 and more reactive fuels have been proposed; however, information on pollutant emissions is still scarce. The present work focuses on quantif

Dialogue with property owners and property developers as a tool for sustainable transformation : A literature review

The housing sector is important for achieving ambitious environmental targets. In the European Union, buildings account for 40% of energy consumption and 36% of CO2 emissions. Considering the scale of the housing sector's environmental impact, interventions in how new housing is built and existing housing is renovated have great potential for sustainable transformation. However, the sector has not

An open multi-physics framework for modelling wildland-urban interface fire evacuations

Fire evacuations at wildland-urban interfaces (WUI) pose a serious challenge to the emergency services, and are a global issue affecting thousands of communities around the world. This paper presents a multi-physics framework for the simulation of evacuation in WUI wildfire incidents, including three main modelling layers: wildfire, pedestrians, and traffic. Currently, these layers have been mostl

Fracture of laminated bamboo and the influence of preservative treatments

Treated bamboo can be made into large, durable structural elements which have the potential to become a transformative large-scale building material, but the fracture behaviour which determines their ultimate strength in various loading scenarios has not been studied. Laminated bamboo is a promising structural engineered bamboo material, and is generally made from bamboo treated to improve its dur

Radium isotopes distribution and submarine groundwater discharge in the Bohai Sea

In order to characterize the radium distribution and submarine groundwater discharge (SGD) in the Bohai Sea area, the three isotopes 223Ra, 224Ra and 228Ra in different water bodies were measured in a 4-year period with the radium-delayed coincidence counting (RaDeCC) system. The results indicated that radium activities take an order of groundwater > coastal seawater > river water > central seawat

Den svenska supply chain-panelen : Supply Chain Information Sharing

Denna femte studie behandlar Supply chain information sharing (SCIS), d.v.s. hur företag delar information i försörjningskedjan. Vi försöker också förstå hur företag delar information i försörjningskedjan - både mellan företagets interna avdelningar/funktioner och med viktiga partners. Analysen bygger på svar från 34 panelmedlemmar.

Prioritizing research challenges and funding for allergy and asthma and the need for translational research—The European Strategic Forum on Allergic Diseases

The European Academy of Allergy and Clinical Immunology (EAACI) organized the first European Strategic Forum on Allergic Diseases and Asthma. The main aim was to bring together all relevant stakeholders and decision-makers in the field of allergy, asthma and clinical Immunology around an open debate on contemporary challenges and potential solutions for the next decade. The Strategic Forum was an

Proteomic signatures of brain regions affected by tau pathology in early and late stages of Alzheimer's disease

Background: Alzheimer's disease (AD) is the most common neurodegenerative disorder. Depositions of amyloid β peptide (Aβ) and tau protein are among the major pathological hallmarks of AD. Aβ and tau burden follows predictable spatial patterns during the progression of AD. Nevertheless, it remains obscure why certain brain regions are more vulnerable than others; to investigate this and dysregulate

Den svenska supply chain-panelen : Supply Chain Risk Management

Den sjätte studien är fokuserad på Supply chain risk management (SCRM), d.v.s. vi försöker förstå hur företag identifierar, analyserar och hanterar risker i sin försörjningskedja. Det gäller både i Risk Management i interna logistikflöden (egna lager, egna fabriker, transporter mellan egna anläggningar etc) men framför allt Supply Chain Risk Management i externa försörjningskedjor (leverantörer, u

Numerical study of a fire-driven flow in a narrow cavity

Air cavities and gaps between material layers are common in construction systems, e.g. ventilated façades. Air cavity may provide a pathway for smoke and flame spread in case of fire. Performing physical testing to investigate different systems and fire scenarios is resource demanding. Fire Dynamics Simulator (FDS version 6.7.0) was used to simulate fire driven flow between two parallel vertical w

Manganese transporter genetics and sex modify the association between environmental manganese exposure and neurobehavioral outcomes in children

There is increasing evidence that environmental manganese (Mn) exposure early in life can have negative effects on children's neurodevelopment and increase the risk of behavioral problems, including attention deficit hyperactivity disorder (ADHD). Factors that may contribute to differences in sensitivity to Mn exposure are sex and genetic variation of proteins involved in the regulation of Mn conc

Familial Urinary Bladder Cancer with Other Cancers

Background: Family risks for urinary tract cancers (excluding kidney cancers) are known, but less is known about whether rare urinary tract cancer subtypes are also familial and if urinary tract cancers share familial risk for other (discordant) cancers. Objective: To investigate the impact of family history on urinary tract cancers (International Classification of Diseases version 7 code 181) and

High exposure to perfluorinated compounds in drinking water and thyroid disease. A cohort study from Ronneby, Sweden

Per- and polyfluoroalkyl substances (PFAS) are extremely persistent manmade substances. Apart from exposure through food and indoor air and dust, humans can be exposed through drinking water if the surface or groundwater is contaminated. In 2013 very high levels of PFOS and PFHxS were found in the drinking water from one of the two waterworks supplying the municipality of Ronneby, Sweden. A cohort
