- The PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.

On context in phenomenographic research on understanding heat and temperate
- 2002
-
Ingår i: EARLI, Bi-annual Symposium, Fribourg, Switzerland.
-
Konferensbidrag (refereegranskat)abstract
- Starting from an empirical study of lay adults' understanding of heatand temperature, we distinguish between different meanings of "context" inphenomenographic research. To confuse the variation in ways of experiencingthe context(s) of the study with the variation in ways of experiencing thephenomenon of study is to risk losing fundamental insights. We discuss contextas experienced and as interwoven with the experience of the phenomenon, andanalyse its significance in two dimensions: (1) the stage of the research project:formulating the question, collecting data, analysing data and deploying results;and (2) "who is experiencing" the context: the individual, the collective, or theresearcher. The arguments are illustrated from the empirical study.

Konferensbidrag (refereegranskat)abstract
- Starting from an empirical study of lay adults' everyday understanding of the scientificconcepts of heat and temperature, we have found it necessary to distinguish betweendifferent meanings of the notion of context in phenomenographic research.In order to reveal interesting and important differences in the ways in which aphenomenon is experienced, the phenomenographic researcher relegates experience ofthe context to the background. To confuse the variation in ways of experiencing thecontext(s) of the study with the variation in ways of experiencing the phenomenon ofstudy is to risk losing fundamental insights.This does not mean, however, that the researcher can neglect the context(s), even if it isnot of main interest. Since the research object of a phenomenographic study is "variationin ways of experiencing something", we discuss context as experienced and interwovenwith the experience of the phenomenon. We argue that the experienced context, thecontext as created and understood by the researcher, and the relation between these arerelevant to varying degrees and in varying ways at different stages of the research project.In our paper we see the experienced context from the perspective of "who isexperiencing" the context: the individual, the collective, or the researcher (whether asphenomenographer or as physicist). This will be illustrated from the empirical data.The proposed distinctions provide a better ground for generalising the results of thestudy, since they help us to understand the differences between the research situation(s)and the research object(s).

The role of computer simulations in university students’ reasoning about physics
- 2006
-
Ingår i: the third Scandinavian Symposium on Research in Science Education, Karlstad, February 2006.
-
Konferensbidrag (refereegranskat)abstract
- The aim of this paper is to describe the different roles that a computersimulation of a physics phenomenon plays in university students’ reasoning aboutphysics. In this way, the paper strives to illuminate the potential value of computersimulations as a tool in students’ learning, as their reasoning around physics problemsimplies possible learning outcomes. Four different ways of using the computer simulationwere discerned from data collected from students working with a simulation of Bohr’smodel of the hydrogen atom. The four categories are distinguished by their characteristicsof Answering, Implying, Interacting and Opening. We describe the categories in moredetail, illustrate them from the empirical data and analyze each of them according to ananalytical model of learning, with a motive, an act and an object of learning. We alsodiscuss the categories in terms of design of pedagogical settings with simulations.

Social and moral psychology of COVID-19 across 69 countries
- 2023

Tidskriftsartikel (refereegranskat)abstract
- The COVID-19 pandemic has affected all domains of human life, including the economic and social fabric of societies. One of the central strategies for managing public health throughout the pandemic has been through persuasive messaging and collective behaviour change. To help scholars better understand the social and moral psychology behind public health behaviour, we present a dataset comprising of 51,404 individuals from 69 countries. This dataset was collected for the International Collaboration on Social & Moral Psychology of COVID-19 project (ICSMP COVID-19). This social science survey invited participants around the world to complete a series of moral and psychological measures and public health attitudes about COVID-19 during an early phase of the COVID-19 pandemic (between April and June 2020). The survey included seven broad categories of questions: COVID-19 beliefs and compliance behaviours; identity and social attitudes; ideology; health and well-being; moral beliefs and motivation; personality traits; and demographic variables. We report both raw and cleaned data, along with all survey materials, data visualisations, and psychometric evaluations of key variables.

Comparative Efficacy of 177Lu and 90Y for Anti-CD20 Pretargeted Radioimmunotherapy in Murine Lymphoma Xenograft Models.
- 2015
-
Ingår i: PloS one. - : Public Library of Science (PLoS). - 1932-6203. ; 10:3

Tidskriftsartikel (refereegranskat)abstract
- Pretargeted radioimmunotherapy (PRIT) is a multi-step method of selectively delivering high doses of radiotherapy to tumor cells while minimizing exposure to surrounding tissues. Yttrium-90 (90Y) and lutetium-177 (177Lu) are two of the most promising beta-particle emitting radionuclides used for radioimmunotherapy, which despite having similar chemistries differ distinctly in terms of radiophysical features. These differences may have important consequences for the absorbed dose to tumors and normal organs. Whereas 90Y has been successfully applied in a number of preclinical and clinical radioimmunotherapy settings, there have been few published pretargeting studies with 177Lu. We therefore compared the therapeutic potential of targeting either 90Y or 177Lu to human B-cell lymphoma xenografts in mice.

- Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project - and avert - future declines. We describe and assess a new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. The database contains more than 1% of the total number of all species described, and more than 1% of the described species within many taxonomic groups - including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems - ). We make site-level summary data available alongside this article. The full database will be publicly available in 2015.

Large-scale migration into Britain during the Middle to Late Bronze Age

Tidskriftsartikel (refereegranskat)abstract
- Present-day people from England and Wales harbour more ancestry derived from Early European Farmers (EEF) than people of the Early Bronze Age1. To understand this, we generated genome-wide data from 793 individuals, increasing data from the Middle to Late Bronze and Iron Age in Britain by 12-fold, and Western and Central Europe by 3.5-fold. Between 1000 and 875 BC, EEF ancestry increased in southern Britain (England and Wales) but not northern Britain (Scotland) due to incorporation of migrants who arrived at this time and over previous centuries, and who were genetically most similar to ancient individuals from France. These migrants contributed about half the ancestry of Iron Age people of England and Wales, thereby creating a plausible vector for the spread of early Celtic languages into Britain. These patterns are part of a broader trend of EEF ancestry becoming more similar across central and western Europe in the Middle to Late Bronze Age, coincident with archaeological evidence of intensified cultural exchange2-6. There was comparatively less gene flow from continental Europe during the Iron Age, and Britain's independent genetic trajectory is also reflected in the rise of the allele conferring lactase persistence to ~50% by this time compared to ~7% in central Europe where it rose rapidly in frequency only a millennium later. This suggests that dairy products were used in qualitatively different ways in Britain and in central Europe over this period.
