Journal article (peer-reviewed)abstract
- Humanity has emerged as a major force in the operation of the biosphere, with a significant imprint on the Earth System, challenging social-ecological resilience. This new situation calls for a fundamental shift in perspectives, world views, and institutions. Human development and progress must be reconnected to the capacity of the biosphere and essential ecosystem services to be sustained. Governance challenges include a highly interconnected and faster world, cascading social-ecological interactions and planetary boundaries that create vulnerabilities but also opportunities for social-ecological change and transformation. Tipping points and thresholds highlight the importance of understanding and managing resilience. New modes of flexible governance are emerging. A central challenge is to reconnect these efforts to the changing preconditions for societal development as active stewards of the Earth System. We suggest that the Millennium Development Goals need to be reframed in such a planetary stewardship context combined with a call for a new social contract on global sustainability. The ongoing mind shift in human relations with Earth and its boundaries provides exciting opportunities for societal development in collaboration with the biosphere-a global sustainability agenda for humanity.

Litteraturens historia i Sverige
- 2013. - 7
-
Editorial collection (other academic/artistic)abstract
- Litteraturens historia i Sverige ges numera ut av Studentlitteratur AB. Denna sjätte upplaga innehåller dock inga förändringar av innehållet jämfört med den femte upplagan. Litteraturens historia i Sverige är en välskriven och inspirerande handbok med skönlitteraturen i centrum. Inom dess pärmar ryms grundläggande fakta och övergripande perspektiv om texter och författare, från Rökstenen och fram till våra dagar. Den femte reviderade upplagan tar litteraturen in i 2000-talet, och läsaren möter bland mycket annat den nya arbetarlitteraturen, chick lit och den svenska deckarboomen. Litterära ikoner som Heliga Birgitta, Selma Lagerlöf och August Strindberg har fått sällskap av samtida författare som Jonas Hassen Khemiri, Henning Mankell och Sara Stridsberg.De tidigare upplagorna av Litteraturens historia i Sverige och Litteraturens historia i världen mottogs med uppskattande recensioner, och båda böckerna används i undervisningen vid universitet och högskolor. Ny layout och nytt bildmaterial i fyrfärg gör denna upplaga än mer tilltalande och läsarvänlig. Litteraturens historia i Sverige är kort sagt en bok för alla som vill orientera sig i nära tusen år av svensk litteraturhistoria. I denna upplaga har Bernt Olssons och Ingemar Algulins texter kompletterats med nyskrivna texter av Anna Williams, Åsa Arping, Annika Olsson, Boel Westin och Annelie Bränström Öhman, litteraturvetare verksamma vid olika universitet i landet.

A system for remote dosimetry audit of 3D-CRT, IMRT and VMAT based on lithium formate dosimetry
- 2014
-
In: Radiotherapy and Oncology. - : Elsevier. - 0167-8140 .- 1879-0887. ; 113:2, s. 279-282
-
Journal article (peer-reviewed)abstract
- The aim of this work was to develop and test a remote end-to-end audit system using lithium formate EPR dosimeters. Four clinics were included in a pilot study, absorbed doses determined in the PTV agreed with TPS calculated doses within ±5% for 3D-CRT and ±7% (k=1) for IMRT/VMAT dose plans.

Investigation of signal fading in lithium formate EPR dosimeters using a new sensitive method
- 2012

Journal article (peer-reviewed)abstract
- The aim of this study was to investigate signal fading in lithium formate electron paramagnetic resonance (EPR) dosimeters used for clinical applications in radiotherapy. A new experimental method for determination of signal fading, designed to resolve small changes in signal from slowly decaying unstable radicals, was used. Possible signal fading in lithium formate due to different storage temperatures was also tested. Air humidity was kept at a constant level of 33% throughout the experiments. The conclusion drawn from the investigations was that the EPR signal from lithium formate is stable during at least 1 month after irradiation and is not sensitive to variations in storage temperature andlt;40 degrees C when kept at a relative air humidity of 33%. This makes lithium formate a suitable dosimeter for transfer dosimetry in clinical audits.

Lithium formate EPR dosimetry for accurate measurements of absorbed dose in radiotherapy
- 2014
-
Doctoral thesis (other academic/artistic)abstract
- Lithium formate has shown to be a material with properties suitable for electron paramagnetic resonance (EPR) dosimetry, among them up to 7 times higher sensitivity compared to alanine, which is a well-established EPR detector material for dose determinations in radiotherapy.The aim of this thesis was to further investigate the properties of lithium formate and develop the dosimetry system towards applications in radiotherapy. The intrinsic efficiency for energies of relevance to brachytherapy and the signal stability were investigated. The dosimetry system was expanded to include a smaller dosimeter model, suitable for measurements in dose gradient regions. An individual sensitivity correction method was applied to the smaller dosimeters to be able to perform dose determinations with the same precision as for the larger ones. EPR dosimetry in general is time consuming and effort was spent to optimize the signal readout procedure regarding measurement time and measurement precision.The system was applied in two clinical applications chosen for their high demands on the dosimetry system: 1) a dosimetry audit for external photon beam therapy and 2) dose verification measurements around a low energy HDR brachytherapy source.The conclusions drawn from this thesis were: dose determinations can be performed with a standard uncertainty of 1.8-2.5% using both the original size dosimeters and the new developed smaller ones. The dosimetry system is robust and useful for applications when high measurement precision and accuracy is prioritized. It is a good candidate for dosimetry audits, both in external beam therapy and brachytherapy.

Fenomenologins möjligheter i etnologin: Rapport från en nationell workshop.
- 2011
-
Reports (other academic/artistic)abstract
- Fredag den 17 december 2010 genomfördes en nationell workshop kring fenomenologins vara i etnologin vid Institutionen för kulturvetenskaper, Lunds universitet. Denna rapport är ett resultat från workshopen och skall ses som ett försök att intensifiera den diskussion som var på workshopen. Etnologin har tagit inspiration från fenomenologin och i denna filosofi har ämnet funnit teorier och metodologier för att utveckla kulturanalysen. Ibland har inspirationen kommit från de fenomenologiska klassikerna - Martin Heidegger, Maurice Merleau-Ponty, Simone de Beauvoir – andra gånger har inspirationen varit antropologer och sociologer som har varit starkt färgade av fenomenologin. Idag vågar vi påstå att det finns en så stor etnologisk diskussion och användning av denna filosofi att vi kan prata om en etnologisk tolkning av fenomenologi.

Centrala universitetsvärden hotas av bolagiseringsidén
- 2013

In: Dagens nyheter. - 1101-2447.

Journal article (pop. science, debate, etc.)abstract
- Högskolestiftelser. Förslaget att driva svenska universitet i stiftelseform öppnar för bolagisering. Men det är ingen riktig utredning, utan en politisk pamflett utan eftertanke. Privatisering av universitet hotar både oberoendet, forskningskvaliteten och samhällsnyttan, skriver 36 forskare vid svenska högskolor och universitet.
