While angiosperm clocks can be described as an intricate network of interlocked transcriptional feedback loops, clocks of green algae have been modelled as a loop of only two genes. To investigate the transition from a simple clock in algae to a complex one in angiosperms, we performed an inventory of circadian clock genes in bryophytes and charophytes. Additionally, we performed functional charac
A new health surveillance protocol for work-related upper-extremity musculoskeletal disorders has been validated by comparing the results with a reference protocol. The studied protocol, Health Surveillance in Adverse Ergonomics Conditions (HECO), is a new version of the reference protocol modified for application in the Occupational Health Service (OHS). The HECO protocol contains both a screenin
Svensk sammanfattningAvhandlingens syfte har varit att studera utvecklingen av en könskromosom i realtid genom att simulera dess framväxt i en hermafroditisk plattmask i laboratoriet. Jag gjorde detta genom att selektera på dels honlig fitness (fitness via ägg), dels hanlig fitness (fitness via spermier) med hjälp av en genetisk markör, som agerade som en könsbestämmande gen. Detta ska efterlikna Sex chromosome evolution in a hermaphrodite ancestor starts with the establishment of a sex-determining region (SDR). Over time, sex-specific genes, and/or sexually antagonistic alleles will become linked to the SDR. Sexually antagonistic alleles are a type of genetic variation that increases fitness for one sex while being detrimental for the other sex. Recombination arrest around the SDR and gen
In their comment piece, van Basshuysen and Brandstedt raise three main issues: first, whether population at the global scale, or individual family planning decisions, are relevant for climate change mitigation; second, they offer useful critiques of the methodologies to attribute greenhouse gas emissions for the choice to have a child; and third, they question the appropriate ethical responsibilit
Transportation of people and goods largely relies on the use of fossil hydrocarbons, contributing to global warming and problems with local air quality. There are a number of alternatives to fossil fuels that can avoid a net carbon emission and can also decrease pollutant emissions. However, many have significant difficulty in competing with fossil fuels due to either limited availability, limited
Popular Abstract in Swedish Hur gick det till när det svenska riket expanderade norrut och införlivade Hälsingland? Denna bok är uppställd som en generalhypotes över denna långt utdragna process, som tar sin utgångspunkt i den samhälleliga kollaps som är skönjbar under 500-talet. De inhemska maktstrukturer som gradvis byggdes upp efteråt kom under medeltidens inledande århundraden att få känna på In which way did the power structures of central Sweden expand into the territories north of the forest Ödmården during the Middle Ages? This text reads like a general hypothesis for this process, which attempts to incorporate all relevant elements in the Medieval landscape of power. The study area chosen is the province of Hälsingland. The chronological take-off is the 6th century AD, when settle
Constrained by national tests and the mathematics curriculum, teachers have problems finding time for exploratory and hands-on mathematical activities, especially so in classes with a reduced pace of progression, for example because of a large proportion of second-language learners. Could the leisure-time center, where time is not earmarked, provide such opportunities? The conclusion of this thesi
Popular Abstract in Swedish Talarålder är en viktig paralingvistisk egenskap i tal, som bör beaktas vid studiet av fonetisk variation. Kunskap om talarålder kan användas för att förbättra talteknologiska tillämpningar såsom automatisk taligenkänning och talsyntes. Föreliggande doktorsavhandling beskriver sex studier som undersökt ett flertal aspekter av den åldersrelaterade variationen i tal. NärSpeaker age is an important paralinguistic feature in speech which has to be considered in the study of phonetic variation. Knowledge about this feature may be used to improve speech technology applications, e.g. automatic speech recognition and speech synthesis. The present thesis describes six studies of several phonetic aspects of age-related variation in speech. As the speech production mecha
This article examines the diffusion of the Balanced Scorecard (BSC) in Swedish municipalities. The point of departure in the article is that there is a gap in our understanding concerning the diffusion of new management tools. Over the last decade, research has largely been based on empirical evidence regarding early adopters. Furthermore, these studies have largely been based on case study eviden
Popular Abstract in Swedish Riksdagen har beslutat att Sveriges energisystem ska ställas om. Målet är ett ekologiskt uthålligt samhälle där staten verkar för en säker, effektiv och miljövänlig tillförsel och användning av energi. Detta görs bland annat genom att stödja forskning om förnybara energikällor. Biogasen är här ett av flera möjliga alternativ och har också utnämnts till det mest miljöanpThe utilisation of energy in the form of biogas is one of the environmentally sound alternatives available using renewable energy sources. Biogas is formed by anaerobic degradation of organic material, the main consistuent being energy-rich methane. There is a large unused potential of organic waste that is suitable for biogas production and the anaerobic digestion process has the potential of bec
There is growing concern about the possible hazards which can result from the use of certain organic building materials. The issue has received a great deal of attention in industrial countries in temperate climates, because indoor air pollution is frequent in tight, energy efficient buildings with low rates of ventilation. This is not yet a problem all over the world, but an awareness of the risk
The concluding chapter first summarizes some of the volume’s main results along the four evaluative themes. In terms of coherence and management, the three policy fields under scrutiny – renewable energy, fossil fuel subsidy reform and carbon pricing – are roughly marked by coordination, rather than competition or outright harmony. Regarding legitimacy, the specializations and work backgrounds of
In 2010, the first, and so far only, infestation of the Hungarian spruce scale (Physokermes inopinatus) and accompanying sooty mould occurred in Scania, southernmost Sweden. About 1000 ha of Norway spruce (Picea abies) were affected, and the trees suffered from the sucking of the insects as well as from the dense sooty mould that covered the needles. Salvage cuttings were carried out in many of th
How do you attract visitors to your city? How do you manage to be visible in the information flow for potential visitors? Urban Destination Marketing Organisations (DMO) operate in a fast changing environment with ongoing challenges to face. Digitalisation is one of the issues that DMOs have to handle. As a result, we can see that many tourism offices are closed down in Sweden. However, has new te
One of the most important trends in contemporary tourism is the increase in urban tourism, both in absolute and in relative terms. In some destinations, e.g. Barcelona, the pressure from tourism on local resources such as housing and urban space has reached a point where we begin to speak about overtourism. The development of overtourism is related to decreasing relative costs of travel, e.g. low-
Fire carbon emissions over Equatorial Asia (EQAS) play a critical role in the global carbon cycle. Most regional fire emissions (89.0%) occur in the dry season, but how changes in the dry-season length affect the fire emissions remains poorly understood. Here we show that, the length of the EQAS dry season has decreased significantly during 1979–2021, and the delayed dry season onset (5.4 ± 1.6 (±
In this study, we examine the development of age at leaving the parental household in Sweden between the years 1830-1959. We utilize individual-level longitudinal data from two geographically and socioeconomically different regions: the county of Scania in the very south of Sweden, and Västerbotten to the north. We use descriptive and multivariate analyses to investigate how determinants, such as
Growing evidence suggests that young migrants are particularly vulnerable to sexual violence. As young migrants often lack family and social networks, professionals are often the recipients of disclosures of sexual violence. This study aimed to explore how professionals experience young migrants’ disclosures of sexual violence. A qualitative design was used, based on 14 semi-structured interviews
In the last two decades, health promotion strategies have gained significant attention in end-of-life care contexts—engendering greater focus on community and informal care in policy and healthcare spheres in liberal welfare-states. The emergence of health-promoting palliative care (HPPC) in the Nordic context presents a unique challenge to the abiding social contract of care which emphasizes the
Innovation literature shows that the characteristics of a company's innovation processes determine their performance in different areas. In this study, we adopt a general conceptual model from innovation theory and apply it to packaging innovation. This helps identify and describe subprocesses in packaging innovation and how to measure their performance. It also links the packaging innovation proc
