Syftet med denna studie har i första hand varit att öka förståelsen av optionsvärdet och dess betydelse för värdering av kollektivtrafik. I andra hand har vi studerat så kallade icke-användarvärden.Begreppet optionsvärde har sitt ursprung i miljöekonomin och uppstår då det råder osäkerhet om framtida konsumtion. Optionsvärdet utgör den premie individer är beredda att betala för att försäkra sig om
Worldwide, information and communication technologies (ICT), particularly in the sense of digital literacy, are increasingly considered as both inevitable and indispensable parts of the school curriculum. Also, international student assessment studies like PISA have on several occasions assessed computer and information literacy. Additionally, classrooms, teaching and learning, as well as school a
Morphological and optical properties were studied and also evolutionary changes of the eye lenses of some species of terrestrial gastropod pulmonate molluscs were traced. It was demonstrated that all examined properties of the lenses are typical for terrestrial pulmonates. In the course of evolution due to habitat shift by mollusks the lenses were changed only slightly.
Biocompatible chemically cross-linked organic-inorganic (O-I) hybrid nanocomposites were developed using a new atoxic, simple and fast, solvent-free pathway. Poly(ϵ-caprolactone) (PCL) and poly(ethylene glycol) (PEG), which are both biocompatible, were used as the organic moieties (at different PCL/PEG ratios), while in situ synthesized polysilsesquioxanes made up the inorganic moiety. The O-I hyb
This paper estimates the impact of university education on medical care use and its income related inequality. We do this by exploiting an arbitrary university eligibility rule in Sweden combined with regression discontinuity design for the years 2003-2013 for students who graduated 2003-2005. We find a clear jump in university attendance due to university eligibility. This jump coincides with a pThis paper estimates the impact of university education on medical care use and its income related inequality.

In present paper, the debates around mediatization and transnationalism constitute the backdrop for a discussion on the media and communication practices among Swedish expatriates in the Netherlands and forced migrants from Bosnia in Sweden. The complex relationship between (transnational) identity, place and mobility is studied at three intersections between media and migration: (1) creativity an
Many cell functions rely on the ability of microtubules to self-organize as complex networks. In plants, cortical microtubules are essential to determine cell shape as they guide the deposition of cellulose microfibrils, and thus control mechanical anisotropy of the cell wall. Here we analyze how, in turn, cell shape may influence microtubule behavior. Buidling upon previous models that confined m
Nanoparticles exposed to biological fluids adsorb biomolecules on their surface forming a biomolecular corona. This corona determines, on a molecular level, the interactions and impact the newly formed complex has on cells and organisms. The corona formation as well as the physiological and toxicological relevance are commonly investigated. However, an acknowledged but rarely addressed problem in
Climate change, increasingly recognized as a hurdle to achieving sustainable development goals, has already begun impacting the lives and livelihoods of people around the world, including on the African continent. Vulnerability is a concept often employed in the context of climate change to identify risks and develop policy and adaptation measures that address current and projected impacts. Howeve
This paper examines a digital employee-oriented innovation program at a global IT-firm. It addresses the research question: how is the generation and promotion of employee ideas organised by the management, and what are the behavioural implications in terms of participation of such an organising? Drawing on the literature on inclusive innovation and employee-driven innovation, the authors explore
We consider adaptive time discretization methods for ordinary differential equations where one aims to control the error in a quantity of interest of the form J(u) = ∫ j(u(t))dt with j : Rd -> R. In this setting we propose a new timestep controller based on local error estimates of the quantity of interest. The new method converges when the tolerance goes to zero.We experimentally compare the new
The body – or, more specifically, women’s bodies – has long been one of feminism’s central topics. This discussion has ranged from explorations of the cultural meaning of biology to the challenging of classification systems regulating bodies not only culturally coded as female or male but also understood through race regimes. This article seeks to explore the location of bodies within Swedish femi
Using exceptionally rich qualitative data coming from the FP7 EUCROSS project on the ‘Europeanization of the Everyday Life’, this paper focuses on high-skilled and highly transnational Turkish migrants who reside in the UK, Romania and Italy. The article analyses participants’ discursive constructions of Europe and Europeanness and shows how specific images and symbols of Europe and Turkey influen
The Komstad Limestone forms a distal part of the widespread ‘orthoceratite limestone’ of the Baltoscandian continent. In this paper, we present an integrated conodont biostratigraphy and carbon isotope stratigraphy for a major part of this formation and address its significance for evaluating Middle Ordovician correlation and overall stratigraphy. Four conodont zones are distinguished, including t
In many cases fragmentation of molecules upon inner-shell ionization is very unspecific with respect to the initially localized ionization site. Often this finding is interpreted in terms of an equilibration of internal energy into vibrational degrees of freedom after Auger decay. We investigate the X-ray photofragmentation of ethyl trifluoroacetate upon core electron ionization at environmentally
