Tidskriftsartikel (refereegranskat)abstract
- Background: Although it is well known that people with multiple sclerosis (PwMS) retire from work early, little is known about how long-term changes in functioning and perceived impact of multiple sclerosis (MS) interact with sustainability of employment.Objective: To explore changes in functioning and in perceived impact of MS over 10 years, in relation to employment status of PwMS.Methods: In order to measure functioning, data on activities (walking ability, fine hand use, personal activities in daily living); participation in activities of everyday life (domestic, outdoor and leisure activities); body functions (cognitive function, fatigue, depressive symptoms); and perceived impact of MS were collected in 116 PwMS at baseline and at a 10-year follow-up. Ten-year changes were explored with the participants divided into four subgroups based on employment status at the follow-up: 1) full-time work at the 10-year follow-up; 2) part-time work at the 10-year follow-up; 3) declined from working at baseline to not working at the 10-year follow-up; and 4) not working at baseline nor at the 10-year follow-up.Results: Patterns of change in functioning for PwMS who worked showed a more apparent deterioration over 10 years among those working part-time with regard to walking ability, fatigue and depressive symptoms. Members of the subgroups who declined from working at baseline to not working at the 10-year follow-up or who were working neither at baseline nor at the follow-up deteriorated the most in functioning. The subgroup whose employment status declined from baseline to follow-up showed a significant decrease in cognitive function and an increase in perceived physical impact of the disease. All subgroups experienced a deterioration in walking ability over the 10-year span, and in all subgroups a majority had limited fine hand use over the span of the study period.Conclusion: The deterioration in functioning was most apparent in those PwMS whose employment status declined from working at baseline to not working at the 10-year follow-up. Close monitoring of work situation and frequency of activities and participation in everyday activities, as well as recurrent training of functioning, are suggested for maintaining a high level of functioning and work status, or for supporting transition to an appropriate number of working hours.

Cumulative impact assessment for ecosystem-based marine spatial planning
- 2020
-
Ingår i: Science of the Total Environment. - : Elsevier BV. - 0048-9697 .- 1879-1026. ; 734

Tidskriftsartikel (refereegranskat)abstract
- Claims for ocean space are growing while marine ecosystems suffer from centuries of insufficient care. Human pressures from runoff, atmospheric emissions, marine pollution, fishing, shipping, military operations and other activities wear on habitats and populations. Ecosystem-based marine spatial planning (MSP) has emerged worldwide as a strategic instrument for handling conflicting spatial claims among competing sectors and the environment. The twofold objective of both boosting the blue economy and protecting the environment is challenging in practice and marine planners need decision support. Cumulative Impact Assessment (CIA) was originally developed to provide an overview of the human imprint on the world's ocean ecosystems. We have now added a scenario component to the CIA model and used it within Swedish ecosystem-based MSP. This has allowed us to project environmental impacts for different planning alternatives throughout the planning process, strengthening the integration of environmental considerations into strategic decision-making. Every MSP decision may entail a local shift of environmental impact, causing positive or negative consequences for ecosystem components. The results from Swedish MSP in the North Sea and Baltic Sea illustrate that MSP certainly has the potential to lower net cumulative environmental impact, both locally and across sea basins, as long as environmental values are rated high and prevailing pressures derive from activities that are part of MSP. By synthesizing innumerous data into comprehensible decision support that informs marine planners of the likely environmental consequences of different options, CIA enables ecosystem-based MSP in practice.

A risk framework for optimising policies for deep decarbonisation technologies
- 2021
-
Ingår i: Energy Research and Social Science. - : Elsevier BV. - 2214-6296 .- 2214-6326. ; 82
-
Tidskriftsartikel (refereegranskat)abstract
- Massive resource infusion and coordination between state and market actors are needed to develop and diffuse deep decarbonisation technologies. This makes wise policy design imperative. Policy-makers are confronted with a plethora of diverging views on which policies are preferable for a low carbon transition, and which interventions, such as R&D funding, information, environmental taxes, or bans, should be employed to achieve necessary and sufficient technological transformation. Focusing on market and technological investment risks, we offer a conceptual framework that explains why no silver bullet policy or single theoretical approach exists in regard to decarbonisation. Our framework highlights that policies need to be designed with these risks in mind and aids in the key task of matching problems and policies, thereby also facilitating judicious use of resources to optimise climate benefits from resources spent.

Cybercultures
- 2021
-
Ingår i: The Oxford handbook of human symbolic evolution. - : Oxford University Press. - 9780198813781
-
Bokkapitel (refereegranskat)abstract
- This chapter aims to describe how cultures have emerged in interactions among users of the multitude of online platforms that have become available over the past few decades. It discusses innovations regarding uses of representations to communicate identity, time, and space in social practices with technology, and how cybercultures are played out in theory and in practice. Cybercultures resemble cultures in the non-virtual world—but display significant differences regarding social rules, identity, and spatiotemporal issues. Case studies of three types of cybercultures in social media: information and knowledge building on Wikipedia, culture, and virtual world building on Second Life, and dating practices on online dating services, such as Tinder, will shed light on how cyberspace allows for developing both symbolic representations and social practices through computer-mediated communication (CMC), and how users are situated in the continuum virtual-real.

Evolution of Language
- 2020

Ingår i: Oxford Bibliographies: Evolutionary Biology. - Oxford : Oxford Bibliographies.

Forskningsöversikt (refereegranskat)abstract
- Why do humans have language at all and how did we become language users? These are central questions in language evolution, but no general consensus exists on the answers, nor even on what methods to use to find answers. This is a complex topic that requires input from many disciplines, including, but not limited to, linguistics, evolutionary biology, palaeoanthropology, neurobiology, archaeology, cognitive science, and primatology. Nobody is an expert in all these areas, and experts in one area sometimes overlook needed input from other areas. Consensus does not even exist among linguists on what language is—opinions range from the physical speech acts themselves to language as an abstract social communication system to language as computational machinery in the individual and to language as an innate species-defining, genetically encoded capacity of humans. These different views of language imply very different evolutionary explanations. At the same time, all of these perspectives have some validity; the speech acts do occur, language use does take place in a social context, the individual language user does somehow produce and parse sentences, and human babies are born with a predisposition for language learning that ape babies lack. The disagreements are mainly a matter of emphasis, namely which aspects are regarded as of primary interest, requiring explanation. The preeminent linguist of the early 20th century, Ferdinand de Saussure, focused on the first two perspectives with his distinction between parole (speech acts) and langue (the social system). The preeminent linguist of the late 20th century, Noam Chomsky, focuses instead on the latter two, especially the computational machinery, and he regards the first two as not worthy of a linguist’s attention. But neither focus is adequate on its own; a viable theory of language evolution must be able to explain all aspects of language, notably both the evolution of the language capacity that resides in each human brain and the evolution of the human social context in which language is used. No generally accepted theory exists today. Instead of a single accepted theory, the field of language evolution is awash with a multitude of different models, scenarios, and hypotheses about how things might have happened. To make matters worse, there is something of a paradigm split in the study of language origins. The split is largely along the line between Saussure and Chomsky mentioned above. To put it simply, those researchers who use the label “biolinguistics” try to explain the origin of Chomsky’s computational machinery (see Biolinguistics) whereas most work on language evolution is concerned with explaining the origins of Saussure’s langue, language as a social system; the latter is here called “mainstream evolutionary linguistics.” Language evolution is not, however, about the origin of individual languages (English, Chinese, etc.). Sometimes “language evolution” is used to refer to diachronic language change in recent times, as studied by historical linguists, and an evolutionary perspective can indeed be fruitful in this area. But this article does not cover that kind of language evolution, except peripherally in Cultural Evolution.

How many protolanguages were there?
- 2021
-
Konferensbidrag (refereegranskat)abstract
- When we talk about protolanguage, it is typically in the singular. The name of this conference series is Exhibit A here, but also e.g. the authoritative Oxford Handbook of Language Evolution talks about “the protolanguage” (Tallerman, 2012, my emphasis). This leads us to imagine a single protolanguage being spoken (or signed or mimed or whatever) at some point in prehistory. At most we imagine multiple successive stages of more and more advanced protolanguages (e.g. Jackendoff & Wittenberg, 2014, Author, submitted a). But rarely has the likely diversity of protolanguages been considered. A literature search for “protolanguages” in the plural mainly returns results referring to the proto-forms ancestral to modern language families (proto-Indoeuropean, etc.); see Robbeets et al. (2020) for an example. There are rare exceptions referring to plural protolanguages in the sense used at this conference (e,g, Donald, 1999, Dowman, 2008) but they still do not have diversity in focus.Is there any reason to believe that linguistic diversity in the world was any less in prehistory than it is today? The answer to that question depends on whether the forces driving linguistic diversification were operative already at the protolinguistic stage. If two groups speaking the same language get separated, their dialects will gradually drift apart over time until mutual intelligibility is lost, the linguistic equivalent of genetic drift in biology; this must have been operative for as long as we had conventionalized language at all. Differential language contact can also cause language change, with different subgroups accumulating different loanwords etc. In this way, diversity begets more diversity, and this would have been operative as soon as some diversity was present. Finally, if language is used as a marker of group identity, a group may intentionally steer their way of speaking away from the neighbors’. This requires a level of meta-linguistic awareness that need not have been present from the beginning. But even without the latter force, linguistic drift and language contact would have been quite sufficient to drive diversity among protolanguages. And even in the absence of synchronic diversity, linguistic drift would create diachronic diversity: over a millennium or so, a modern language changes beyond intelligibility, and across 10,000 years it changes beyond recognition even at the family level. Even if we assume for the sake of the argument that protolanguage was a single lineage, every 1,000 years what is spoken deserves to be called a new language.A single lineage is, however, extremely unlikely. From the dawn of language, people have spread out over multiple continents, far out of touch with each other. Protolanguages must have diverged. But populations were sparse, estimates for world population at relevant times are typically below one million, sometimes well below (e.g. Huff et al. 2010), living in small tribes. From such numbers, a rough order-of-magnitude estimate of the total number of protolanguages ever spoken can be calculated (Author, submitted b). With any reasonable assumptions, the number is huge, much larger than current linguistic diversity.

Hur var namnet? : Namntraditioner från alla tider och platser
- 2023. - 1
-
Bok (populärvet., debatt m.m.)abstract
- Vad heter du? Den frågan har du fått många gånger.Men varför heter du? Den frågan har du kanske inte tänkt på så ofta. Hur kommer det sig att du över huvud taget har ett namn, och varför ser det ut som det gör? Det vill Sverker Johansson berätta om i denna underhållande och tankeväckande bok. Med blick för såväl de stora utvecklingslinjerna som för de kuriösa exemplen rör han sig mellan alla tider och platser för att fånga in namntraditionernas mångfald.Beroende på var vi hamnar i tid och rum kan ett förnamn bestämmas utifrån veckodag, förfäder, vilka onda andar som ska luras eller vad modern ser när barnet föds. Förutom förnamn kan vi ha efternamn – men också föräldranamn, gårdsnamn, bynamn, barnnamn, kastnamn, mellannamn, generationsnamn eller tillnamn baserade på allt från lyten via yrken till tv-program. Visste du till exempel att Caligula betyder barnstövlar, att John är det vanligaste förnamnet på Wikipedia, att delfiner har namnmelodier och att Mao Zedongs mellannamn Ze kommer från en dikt som hans släkt i fjorton generationer hämtade namn ur?Mycket pekar på att vi bär namn inte så mycket för att kunna tilltalas som för att kunna omtalas…
