In this paper, we propose a time-recursive multipitch estimation algorithm using a sparse reconstruction framework, assuming that only a few pitches from a large set of candidates are active at each time instant. The proposed algorithm does not require any training data, and instead utilizes a sparse recursive least-squares formulation augmented by an adaptive penalty term specifically designed to

Post Conflict Futures is an ongoing project, where displaced Syrian academics meet in Visioning Labs and a global scenario group to jointly reflect on possible future developments and to look for actionable leverage points to work proactively for sustainable transitions. The collective visioning aims to identify aspects that may be critical in strategies for sustainable post conflict reconstructio

Humlesugan, Betonica officinalis L., är en avden skandinaviska florans sällsyntaste växteroch samtidigt en av de arter som har denlängsta dokumenterade historien. Den rapporteradesfrån Stehag väster om Ringsjön i Skåneav Christiern Pedersen redan 1534, Skånesäldsta litteraturuppgift där en växtart knytstill en lokal. I övriga Danmark beskrevs denmed lokaluppgift första gången av Peder LauridsenKyl

Hohe Tauern i Österrike är en av Europas vackrastenationalparker. I det artrika alplandskapet finnsbåde helt skyddade områden och zoner där bl.a.boskapsskötsel och bergsbruk tillåts.

To promote attainment and inclusion, Sweden offers tuition in migrant pupils’ mother tongues as a regular school subject. However, the formulation of learning aims is problematic, and resources allocated to the subject do not correspond to ambitions expressed in steering documents. This case study presents an analysis of the organization of Mother Tongue Studies at a highly diverse urban primary s

Global teaching and learning for sustainable development reaches from the classroom to the world outside, and is therefore a particularly interesting setting for practising transition skills. The article suggests a number of features perceived as crucial in developing young people's capability to act in a changing world and under circumstances that are difficult to predict. The suggestions are bas

Providing equal access to health care is an important objective in most health care systems. It is especially pertinent in systems like the Swedish primary care market, where providers are free to establish themselves in any part of the country. To improve equity in access to care, 15 out 21 county councils in Sweden have implemented risk-adjusted capitation based on the Care Need Index, which inc

The article presents results of a study made in the context of introducing bilingual instruction in Swedish and Arabic. Classroom interaction was videotaped in grades one to four at two urban schools. Based on the video material, an inventory was made of how Arabic was used by the bilingual teachers, and how it related to the corresponding Swedish content. Simplified language use, code-switching a

In this paper we compute long-term stock return expectations (across the business cycle) for individual firms using information backed out from the credit derivatives market. Our methodology builds on previous theoretical results in the literature on stock return expectations and, empirically, we demonstrate a close relationship between credit-implied stock return expectations and future realized

Any new technology and any form of contact between cultures will necessarily lead to change. ICTs are in this sense far from unique. However, ICTs have rapidly come to occupy a prominent position our societies, and are shaping the lives of young people in ways that we could not have imagined only a decade ago. These technologies allow almost immediate access to a wealth of knowledge and knowhow, a

Artikeln redogör för en intervjustudie som gjordes med 15 internationella studenter på ett mastersprogram med inriktning mot hållbar utveckling, där undervisningen ägt rum på engelska. Studenterna frågades i individuella intervjuer på engelska hur de ansåg att stora översvämningar kunde förebyggas. En intentional-expressiv dialogstruktur anpassades till att innefatta frågor om hur nyckeluttryck i

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
