First Dating of a Recombination Event in Mammalian Tick-Borne Flaviviruses
- 2012
-
Ingår i: PLoS ONE. - 1932-6203. ; 7:2, s. e31981

Tidskriftsartikel (refereegranskat)abstract
- The mammalian tick-borne flavivirus group (MTBFG) contains viruses associated with important human and animal diseases such as encephalitis and hemorrhagic fever. In contrast to mosquito-borne flaviviruses where recombination events are frequent, the evolutionary dynamic within the MTBFG was believed to be essentially clonal. This assumption was challenged with the recent report of several homologous recombinations within the Tick-borne encephalitis virus (TBEV). We performed a thorough analysis of publicly available genomes in this group and found no compelling evidence for the previously identified recombinations. However, our results show for the first time that demonstrable recombination (i.e., with large statistical support and strong phylogenetic evidences) has occurred in the MTBFG, more specifically within the Louping ill virus lineage. Putative parents, recombinant strains and breakpoints were further tested for statistical significance using phylogenetic methods. We investigated the time of divergence between the recombinant and parental strains in a Bayesian framework. The recombination was estimated to have occurred during a window of 282 to 76 years before the present. By unravelling the temporal setting of the event, we adduce hypotheses about the ecological conditions that could account for the observed recombination.

Taxonomic surrogacy in biodiversity assessments, and the meaning of Linnaean ranks
- 2006
-
Ingår i: Systematics and Biodiversity. ; 4, s. 149-159
-
Tidskriftsartikel (refereegranskat)abstract
- The majority of biodiversity assessments use species as the base unit. Recently, a series of studies have suggested replacing numbers of species with higher ranked taxa (genera, families, etc.); a method known as taxonomic surrogacy that has an important potential to save time and resources in assesments of biological diversity. We examine the relationships between taxa and ranks, and suggest that species/higher taxon exchanges are founded on misconceptions about the properties of Linnaean classification. Rank allocations in current classifications constitute a heterogeneous mixture of various historical and contemporary views. Even if all taxa were monophyletic, those referred to the same rank would simply denote separate clades without further equivalence. We conclude that they are no more comparable than any other, non-nested taxa, such as, for example, the genus Rattus and the phylum Arthropoda, and that taxonomic surrogacy tacks justification. These problems are also illustrated with data of polychaetous annelid worms from a broad-scale study of benthic biodiversity and species distributions in the Irish Sea. A recent consensus phylogeny for polychaetes is used to provide three different family-level classifications of polychaetes. We use families as a surrogate for species, and present Shannon-Wiener diversity indices for the different sites and the three different classifications, showing how the diversity measures rely on subjective rank allocations.

Argumentationsanalys : Färdigheter för kritiskt tänkande
- 2009
-
Bok (övrigt vetenskapligt)abstract
- Ny reviderad utgåva.Att tänka kritiskt är att självständigt ta ställning till rimligheten i påståenden och argument. Det är en ovärderlig förmåga när vi ställs inför frågor där svaren är många och motstridiga och argumentationen pekar i olika riktningar. I sådana situationer kan det vara svårt att skaffa sig överblick över argumenten, ta ställning till deras styrka och göra en samlad bedömning av alternativen. Lyckligtvis är detta svårigheter som går att hantera med just sådana verktyg som Argumentationsanalys erbjuder. Genom att använda dem förbättrar vi vår förmåga att både identifiera argument i text och tal och bedöma deras beviskraft. Den som själv behöver skriva en argumenterande text eller göra ett argumenterande framförande har dessutom god hjälp av bokens metod att åskådliggöra hur olika argument i en viss fråga förhåller sig till varandra. Argumentationsanalys är en teoretisk och praktisk handledning med övningar. Boken riktar sig till studenter i humanistiska och samhällsvetenskapliga ämnen, men också till alla andra som konfronteras med komplicerade argumentationer.

Mobile Generations : The Role of Mobile Technology in the Shaping of Swedish Media Generations
- 2009
-
Ingår i: International Journal of Communication. - 1932-8036. ; :3, s. 108-124
-
Tidskriftsartikel (refereegranskat)abstract
- It is often argued that young people are among the first to adopt new mediatechnologies, and that they are especially keen on taking on all new featuresconnected with mobile technology and the Internet. In spite of this oft-repeatedclaim, one could suspect that since computers and mobile phones have become sowidespread among large portions of the populations in the industrialised world, itmight not be technology, per se, that distinguishes the young from the old, butrather the actual ways in which it is used. One approach to discuss this is in termsof media generations. It could be expected that generations that have grown upwith different mediated experiences during their formative years will relate to themobile technology in a variety of ways (cf. Mannheim, 1952 & Volkmer, 2006). Inthis article, three such generations are analysed: the radio/print generation (born inthe 1930s), the TV generation (born in the 1950s), and the mobile technologygeneration (born in the 1980s). Access and usage patterns are researched, and thedegree to which the three generations differ when it comes to their relations tomobile technology is discussed, but also the unifying character of the mobiletelephony usage. Our methodological approach is quantitative, analysing resultsfrom annually conducted postal surveys that are representative for the Swedishpopulation.
