Konferensbidrag (refereegranskat)abstract
- We present a comparative study of Finnish and Swedish free-text nursing narratives from intensive care. Although the two languages are linguistically very dissimilar, our hypothesis is that there are similarities that are important and interesting from a language technology point of view. This may have implications when building tools to support producing and using health care documentation. We perform a comparative qualitative analysis based on structure and content, as well as a comparative quantitative analysis on Finnish and Swedish Intensive Care Unit (ICU) nursing narratives. Our findings are that ICU nursing narratives in Finland and Sweden have many properties in common, but that many of these are challenging when it comes to developing language technology tools.

The role of singletons in S 7 compactifications
- 2019
-
Ingår i: Journal of High Energy Physics. - 1029-8479 .- 1126-6708. ; 2019:7

Tidskriftsartikel (refereegranskat)abstract
- We derive the isometry irrep content of squashed seven-sphere compactifications of eleven-dimensional supergravity, i.e., the left-squashed (LS7) with N = 1 and right-squashed (RS7) with N = 0 supersymmetry, in a manner completely independent of the round sphere. Then we compare this result with the spectrum obtained by Higgsing the round sphere spectrum. This way we discover features of the spectra which makes it possible to argue that the only way the round spectrum can be related by a Higgs mechanism to the one of LS7 is if the singletons are included in the round sphere spectrum. For this to work also in the RS7 case it seems that the gravitino of the LS7 spectrum must be replaced by a fermionic singleton present in the RS7 spectrum.

Lake Vänern: A historical outline

- © 2014, Copyright © AEHMS. Although Lake Vänern is the largest freshwater reservoir in Western Europe, it remains relatively unknown to the scientific community outside of Scandinavia. Therefore, we aim to give a brief outline of the lake and its geological history, in particular the landscape transformation, resource utilization, pollution history, and environmental development of the region. The landscape around Lake Vänern was shaped into its present form during the latest glaciations some 10,000years ago. Large variation exists in its tributaries, with forest in the north and agricultural areas in the south. Human influence on the landscape was relatively small until the mid-18th century. Later, in the mid-19th century, the agriculture, forestry and shipping industries underwent large transformations as the towns around the lake grew and the economy changed. Development of fishing equipment, processes and changes in catching methods industrialized the fishing industry after mid-20th century. In the 1960s the lake was considered to be one of the most heavily mercury-polluted lakes in the world. After the passing of the first national environmental protection law in Sweden the lake turned into a success story: It has been declared to be healthy. However, old pollution still affects the fishing industry. With this new focus on the environment, the scientific community started to be interested in the lake. The lake has also played a very important role as the largest hydropower reservoir in Sweden. Here, too, the environmental question is in focus and the effects of the water regulation are still under debate. The result has been loss of biodiversity and an increased risk of an inflow of invasive species from international shipping. However, still many questions remain to be answered regarding the lake and effect of ongoing climate change on the sustainable development of the lake region.

Psychoacoustic evaluation as a tool for optimization in the development of an urban soundscape simulator
- 2010
-
Ingår i: Proceedings of the 5th Audio Mostly - A Conference on Interaction With Sound, AM '10. - New York, NY, USA : ACM. - 9781450300469 ; , s. 1859802-

Konferensbidrag (refereegranskat)abstract
- This paper will discuss the use of psychoacoustic evaluation as a tool for optimization of the soundscape simulator developed in the Listen project. The listen project is a three-year research project focused around developing a demonstrator, which auralizes the sound environment produced by road and railway traffic. The resolution of the parameter space of the simulator heavily influences the performance of the simulator. The perceptual resolution of the parameter space is investigated and the resolution is adjusted accordingly. The most important parameter is velocity. Adjustments of the resolution of this parameter alone gives a 60% reduction of the usage of memory.

The Early Upper paleolithic deposit of Mughr el-Hamamah (Jordan): Archaeobotanical taphonomy and site formation processes
- 2024

- With a rich, well-dated Early Upper Palaeolithic layer, the Mughr el-Hamamah cave site is key for understanding the Middle-Upper Palaeolithic transition in the Levant. The archaeological deposit consists of two units. Layer A resulted from pastoral activities during the 20th century and Layer B dated between 44.5 and 40.0 ky BP. During Layer A’s formation, shepherds disturbed Layer B, redepositing Early Upper Palaeolithic sediments and lithic artefacts in Layer A matrix. Activity from Layer A’s formation also resulted in spatially patchy percolation and bioturbation, leaving microarchaeological traces such as dung spherulites in some areas in Layer B. In contrast, contemporaneous chemical diagenetic processes from Layer B’s primary formation caused spatially uneven post-depositional dissolution of animal bone. In this article we present a multi-proxy microarchaeological approach to investigate the post-depositional processes in Layer B, focussing on possible impacts on the plant archaeological record. The identification of intrusive spherulites from shepherds’ activities define the limits of disturbance in Layer B. Micromorphological analyses have identified four intact micro-facies in Layer B, representing an interplay of natural and anthropogenic factors. Micromorphological details in bedded combustion features favour the interpretation that associated phytoliths represent fuel traces. Dicot fruit phytoliths occur in the western area of the cave, where well-preserved charred wood and seeds were also found. Grass-diagnostic phytoliths correspond to C3 and C4 taxa, indicating an overall humid environment with dry spells. Microarchaeological analysis identifies traces of both bedded and dispersed hearth materials, mixed with variable plant resources for food, fuel, and possibly other uses. This strengthens the interpretation of Mughr el-Hamamah Layer B as a dense, complicated palimpsest of recurring activities, formed over many millennia.

A field experiment on the impact of sounds from a jet-and-basin fountain on soundscape quality in an urban park
- 2014

Ingår i: Landscape and Urban Planning. - : Elsevier BV. - 0169-2046 .- 1872-6062. ; 123, s. 49-60

Tidskriftsartikel (refereegranskat)abstract
- A field experiment was conducted to explore whether water sounds from a fountain had a positive impact on soundscape quality in a downtown park. In total, 405 visitors were recruited to answer a questionnaire on how they perceived the park, including its acoustic environment. Meanwhile the fountain was turned on or off, at irregular hours. Water sounds from the fountain were not directly associated with ratings of soundscape quality. Rather, the predictors of soundscape quality were the variables “Road-traffic noise” and “Other natural sounds”. The former had a negative and the latter a positive impact. However, water sounds may have had an indirect impact on soundscape quality by affecting the audibility of road-traffic and natural sounds. The present results, obtained in situ, agree with previous results in soundscape research that the sounds perceived—particularly roadtraffic and natural sounds—explain soundscape quality. They also agree with the results from laboratory studies that water sounds may mask road-traffic sounds, but that this is not simple and straight forward. Thus sound should be brought into the design scheme when introducing water features in urban open spaces, and their environmental impact must be thoroughly assessed empirically.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- A new report confirms that we are responsible for global warming. The continued melting of the Arctic’s sea ice is now widely seen to be true. So too is the idea that this has major global consequences. Is the situation reversible?
