Based on the multi-currency LIBOR Market Model, this paper constructs a hybrid commodity interest rate market model with a stochastic local volatility function allowing the model to simultaneously fit the implied volatility surfaces of commodity and interest rate options. Since liquid market prices are only available for options on commodity futures, rather than forwards, a convexity correction fo
We analyze the impacts of changing dry season length and intensity on vegetation productivity and biomass. Our results show a wetness asymmetry in dry ecosystems, with dry seasons becoming drier and wet seasons becoming wetter, likely caused by climate change. The increasingly intense dry seasons were consistently correlated with a decreasing trend in net primary productivity (NPP) and biomass fro
Recent evidence shows that warm semi-arid ecosystems are playing a disproportionate role in the interannual variability and greening trend of the global carbon cycle given their mean lower productivity when compared with other biomes (Ahlström et al. 2015 Science, 348, 895). Using multiple observations (land-atmosphere fluxes, biomass, streamflow and remotely sensed vegetation cover) and two state
The present study was undertaken in the frame of the research programme Language Use and Individual Learning at the Department of Education at Lund University, using the intentional-expressive dialogue format developed within this programme. The dialogue format was adjusted to study language use and understanding in a multilingual and interdisciplinary higher education context, by including questi

PurposeThe paper aims to provide a conceptual map of how to mediate between sustainability theory and practice in higher education and how disciplinary divides can be bridged. It further looks at issues linked to knowledge views and drivers for institutional change that affect opportunities for whole institution development promoting action preparedness.Design/methodology/approachTaking its point
In Sweden, tutoring in the mother tongue is a special support measure primarily intended for newly arrived students to facilitate their transition into the Swedish school system. Tutoring is premised on the collaboration between the class teacher, responsible for subject-related expertise, and the tutor, who contributes with knowledge of the student’s mother tongue and previous context of studies.
Libraries are critical learning spaces and may play a significant role in intercultural education initiatives, particularly in Sweden where the national curriculum ascribes central functions to libraries for learning activities. Unfortunately, the ways in which teachers and librarians may collaborate to leverage mutual resources is not fully understood. This article uses Pirjo Lahdenperä’s model o
L’article discute des pratiques d’engagement et de développement de littératies menées par un réseau debibliothèques scolaires et publique intégrées, dans un quartier urbain multiethnique en Suède. La discussion traite enparticulier les modalités de collaboration avec l’école, les familles, les associations, les centres de loisirs et autres acteursdu quartier, ainsi que les stratégies mises en pla
Oxidation of HSO3- in aqueous solution has been studied in the presence of vanadium(V), chromium(III) and chromium(VI). Based on spectrophotometric kinetics data and product analysis it is concluded that the autoxidation rate of sulfur(IV) in slightly acidic solution is unaffected by the presence of vanadium(V) and chromium(III). Chromate(VI), on the other hand, oxidizes sulfur(IV) in a direct red
Refugees arrive in Sweden in connection with wars and repressive conditions in their countries of origin or refuge. Recently, many have come from the Middle East, and Syria in particular. The situation of refugees has a wide range of consequences for education in the host country, including higher education. Validation and admissions procedures involve administrative challenges, and language is an
Interdisciplinary interaction between the areas of language acquisition and language policy can be considered as a process and analysed from the methodological meta-perspective of how it interrelates with institutional practices. Mother tongue tutoring in Sweden is used to illustrate impacts when concepts travel across disciplinary and institutional contexts.
Spectrophotometric equilibrium measurements indicate formation of the complexes [Pd(H2O)(3)HSO4](+) and [Pd(H2O)(3)SO4] in the reaction between [Pd(H2O)(4)](2+) and hydrogen sulfate/sulfate in the region: 0.10 less than or equal to [H+] less than or equal to 0.80 M. The stability constants are 0.7 +/- 0.2 and 19 +/- 6 M-1, respectively, at 25 degrees C and 1.00 M ionic strength. The protolysis con
