- Metal centers in transition metal–ligand complexes occur in a variety of oxidation states causing their redox activity and therefore making them relevant for applications in physics and chemistry. The electronic state of these complexes can be studied by X-ray absorption spectroscopy, which is, however, due to the complex spectral signature not always straightforward. Here, we study the electronic structure of gas-phase cationic manganese acetylacetonate complexes Mn(acac)1–3+ using X-ray absorption spectroscopy at the metal center and ligand constituents. The spectra are well reproduced by multiconfigurational wave function theory, time-dependent density functional theory as well as parameterized crystal field and charge transfer multiplet simulations. This enables us to get detailed insights into the electronic structure of ground-state Mn(acac)1–3+ and extract empirical parameters such as crystal field strength and exchange coupling from X-ray excitation at both the metal and ligand sites. By comparison to X-ray absorption spectra of neutral, solvated Mn(acac)2,3 complexes, we also show that the effect of coordination on the L3 excitation energy, routinely used to identify oxidation states, can contribute about 40–50% to the observed shift, which for the current study is 1.9 eV per oxidation state.

Journal article (peer-reviewed)abstract
- 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 deras svar kunde uttryckas på studenternas modersmål. Studenterna fick sedan jämföra och kontrastera uttryckssätten och betydelserna som de använt i sina förklaringar, på engelska och på modersmålet. Deras skiftande språkliga och ämnesmässiga bakgrund speglades generellt genom en bred variation i uppfattningarna av frågeställningen, och i studenternas reaktioner till intervjusituationen. Resultaten visar att dialogstrukturen dessutom fick många av studenterna att inkludera andra aspekter i sina förklaringar, när frågan om uttryck och innebörder på modersmålet infördes, än när de först förklarat enbart på engelska.

Factors influencing deprescribing for residents in Advanced Care Facilities : insights from General Practitioners in Australia and Sweden
- 2016

Journal article (peer-reviewed)abstract
- Background: General Practitioners (GPs) are responsible for primary prescribing decisions in most settings. Elderly patients living in Advanced Care Facilities (ACFs) often have significant co-morbidities to consider when selecting an appropriate drug therapy. Careful assessment is required when considering appropriate medication use in frail older patients as they have multiple diseases and thus multiple medication. Many physicians seem reluctant to discontinue other physicians' prescriptions, resulting in further polypharmacy. Therefore it is relevant to ascertain and synthesise the GP views from multiple settings to understand the processes that might promote appropriate deprescribing medications in the elderly. The aims of this study were to 1) compare and contrast behavioural factors influencing the deprescribing practices of GPs providing care for ACF residents in two separate countries, 2) review health policy and ACF systems in each setting for their potential impact on the prescribing of medications for an older person in residential care of the elderly, and 3) based on these findings, provide recommendations for future ACF deprescribing initiatives. Methods: A review and critical synthesis of qualitative data from two interview studies of knowledge, attitudes, and behavioural practices held by GPs towards medication management and deprescribing for residents of ACFs in Australia and Sweden was conducted. A review of policies and health care infrastructure was also carried out to describe the system of residential aged care in the both countries. Results: Our study has identified that deprescribing by GPs in ACFs is a complex process and that there are numerous barriers to medication reduction for aged care residents in both countries, both with similarities and differences. The factors affecting deprescribing behaviour were identified and divided into: intentions, skills and abilities and environmental factors. Conclusions: In this study we show that the GPs' behaviour of deprescribing in two different countries is much dependent on the larger health care system. There is a need for more education to both GPs and ACF staff as well as better cooperation between the different health care systems and appropriate monetary incentives for elderly care to achieve better conditions for deprescribing practice.

Large spin alignment of the unbound He-5 fragment after fragmentation of 240 MeV/nucleon He-6
- 1997

Journal article (peer-reviewed)abstract
- Peripheral fragmentation of a 240 MeV/nucleon beam of the halo nucleus He-6 incident on carbon target has been studied in a kinematically complete experiment. It is found that one-neutron stripping to the unbound nucleus He-5 is the dominant fragmentation mechanism and that it leads to a spin alignment of He-5 in a plane perpendicular to the He-5 momentum vector. This is expected to be a common feature for all neutron halo nuclei.
