Ingår i: Almedalsveckan.
-
Konferensbidrag (populärvet., debatt m.m.)abstract
- Välfärdens utmaningar måste bemötas med innovativa och förebyggande arbetssätt och en helt ny användning av teknik. Men hur skapar man innovationer i vårdens och omsorgens vardag? Hur kan man se det friska i människan och hur kan medarbetare, patienter/brukare och närstående tillsammans hitta nya arbetssätt som gör vården och omsorgen bättre? Bräcke diakoni driver tillsammans med Famna, Jönköping Academy och Alkit Communication AB Famnas testbädd för en personcentrerad vård och omsorg. I den bygger man ett stöd för idéburna vård- och omsorgsgivare för att utveckla nya idéer till spridningsbara innovationer med fokus på de vi finns till för. I ett första test på Bräcke diakoni skapar man möjligheter att möta den enskildes behov och önskemål. Arbetet utgår från en strukturerad dokumentation och uppföljning som med hjälp av ICF och nya IT-stöd följer den enskildes väg genom vården och omsorgen. Möt Famnas testbädd, Vinnova och Äldreutredningen för att diskutera framtidens vård och omsorg.

Optics of coated paperboard : Aspects of surface treatment on porous structures
- 2010
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Calendering of coated and uncoated paper is widely used to enhance optical properties such as gloss and print quality. The aim of this thesis is to characterize coatings and prints, and to validate models using experimental results from optical measurements of physical samples. Calendering of coated paper often leads to a brightness decrease. The mechanism for this is not altogether clear. One common explanation is that the porosity of the coating layer decreases and hence the scattering decreases. By comparing simulated and measured results it was shown that modifications of the surface properties account for the brightness decrease of ground calcium carbonate coated substrates with calendering. Monte Carlo light scattering simulations, taking into account the measured decrease of surface microroughness and increased effective refractive index, showed that surface modifications accounted for most of the observed brightness decrease of the ground calcium carbonate coated substrate, whereas the bulk scattering and absorption coefficients were not affected by calendering. It was also shown that the scattering coefficient is significantly dependent on the coat weight whereas the physical absorption coefficient is not. The penetration of ink in the z-direction of a substrate influences the quality of the print. The ink penetration affects print density, mottling and dot gain, common print effects that influence the preference of consumers. The pressure in the printing nip and the porosity of the substrate both affect the amount of ink that is pressed into the porous structure of a coating layer during printing. By printing pilot coated paperboard with different coating porosity and measuring the resulting optical properties of the prints, a basis for simulations of the different layers, that is to say the coating, the print and the mixed layer in between, was created. Results show that ink distribution is strongly affected by the roughness of the substrate. Fibres and fibre flocks underneath the two coating layers created an unevenly distributed coating thickness that affected the print quality. Differences in pore size and pore size distribution also affected the behaviour of the ink. A coating layer of broad pigment particle size distribution resulted in a relatively low print density, in comparison to coatings of narrowly distributed particle sizes. Comparison of dot gain showed that the coating layer of a narrow particle size distribution had a relatively low dot gain compared to others. In this work, these results are explained by the differences in ink distributions on and in the coating layers.

- 2014
-
Ingår i: Animal Movement Across Scales. - : Oxford University Press. - 9780199677184 ; , s. 259-267
-
Bokkapitel (refereegranskat)abstract
- This chapter aims at synthesizing the knowledge presented in the chapters of the book’s three sections by addressing evolutionary compromises, dispersal, gene flow, and assisted movements. How climate change and other environmental changes at different scales may affect animal movement, migration, and dispersal in the future are also summarized here. Moreover, how the different senses are utilized for navigation and orientation and how these may lead to different movement and migration patterns are also discussed. Finally, how the recent technical revolution has affected animal movement research is addressed and the view on future perspectives of animal movement research is also provided.

Ergonomic Evaluation of Two Different Locations of the Scales in a Supermarket Checkout System
- 1993
-
Ingår i: Advances in Industrial Ergonomics and Safety V. ; , s. 667-674
-
Konferensbidrag (refereegranskat)abstract
- The aim of this pilot study was to ergonomically evaluate the effect of the location of the scales in a supermarket checkout system. A location of the scales to the left of the cashier was compared with a location under the conveyor belt. Two cashiers were videotaped while working with the two scale locations, in both sitting and standing working postures. Analysis of the video tapes was performed using the WOPALAS method, the VIRA method, and by noting certain positions of the left arm. The left wrist movements were registered by a two-dimensional goniometer. The results indicate that the location under the conveyor belt is somewhat more ergonomically favourable. The improvement is more pronounced for the cashier with a greater reach.

Dentists and eating disorders - knowledge, attitudes, management and experience
- 2009
-
Ingår i: Swedish Dental Journal. - : Swedish Dental Association. - 0347-9994. ; 33:1, s. 1-9
-
Tidskriftsartikel (refereegranskat)abstract
- The aims of the present study were to explore the level of knowledge and attitudes among dentists in relation to patients with eating disorders (ED) and evaluate the extent to which patients with ED are identified and/or treated in the dental setting. A postal questionnaire was constructed and sent to all dentists (n=367) in two Swedish counties during November 200S. The questionnaire comprised 29 questions or statements in the following categories: demographics, general knowledge of ED and its oral consequences, experience of and attitudes towards patients with ED and interaction within the health care system,for example, referrals and treatment options regarding this patient group. The response rate was 70% (n=258). Perceived knowledge about ED was most commonly obtained from media sources, namely newspapers, television, etc. Few dentists knew that there existed specialized referral units for ED patients in their county. The majority of dentists stated that they had seen only a few such patients during their practice. Even though the perceived level of general knowledge about ED among female dentists appeared to be better than among male dentists,they also found it more difficult to inform the patient/relatives about their suspicion of the condition. Female dentists referred to specialists significantly more frequently than did males. Eighty-six percent of responders reported that they needed more training in dental management of patients with ED. Knowledge and clinical experience of dentists as regards patients with ED were found to be low. The level of education in this area needs to be improved, which would have the potential to encourage dentists to become more involved in secondary and tertiary prevention and management of ED.

Eating disorders : knowledge, attitudes, management and clinical experience of Norwegian dentists
- 2015
-
Ingår i: BMC Oral Health. - : BioMed Central (BMC). - 1472-6831. ; 15
-
Tidskriftsartikel (refereegranskat)abstract
- Background: The purpose of this study was to investigate knowledge, attitudes and clinical experience with regard to patients with eating disorders (ED) among Norwegian dentists. Methods: In 2010, a questionnaire was sent to all dentists in Norway (N = 4282) comprising 33 questions related to demographics of the participating dentists, their knowledge of ED (general and oral health aspects), clinical experience, attitudes and perceived management preferences. Results: The participation rate was 40 % (47 % women and 53 % men). Their knowledge about ED was often retrieved from common media sources and the greater part of the participants reported they had seen very few patients with ED during their professional career. Female dentists reported superior knowledge about ED compared to males, but the former experienced greater difficulties to inform about the condition. Referrals of the patient to other health facilities were significantly more common among female compared to male dentists. The majority of dentists (76 %) reported a need of more education related to ED management. Conclusions: The Norwegian dentists in this study reported limited clinical experience and insufficient knowledge regarding ED. There is therefore a need to increase both undergraduate and continuing education in this field, which can improve preventive and management measures that a dentist can provide for ED patients.

Svavel- och kvävenedfalletöver Stockholms län
- 1997
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Rapporten presenterar resultat från spridningsberäkningar och mätningar av svavel- ochkvävenedfallet för perioden oktober 1994 — september 1995 (ett hydrologiskt år). Förberäkningarna används spridningsmodeller som utvecklats speciellt för Stockholms länoch som ingår i miljöövervakningssystemet som drivs av Luftvårdsförbundet i Stockholmslän.Modellberäkningarna ger halter av svaveldioxid och kväveoxider för varje timme med4x4 kilometers upplösning i hela länet. Torr- och våtdepositionen har summerats tillmånadsvärden. För beräkningarna används en detaljerad emissionsdatabas samt resultatenfrån ett stort antal mätningar av meteorologi, deposition, krondropp och föroreningshaltersom genomförts inom ramen för Luftvårdsförbundets och Länsstyrelsensregionala miljöövervakning. Beräkningarna jämförs med mätningar.Våtdepositionen av svavel och kväve är till största delen beroende av nederbördens geografiskafördelning, som varierar kraftigt p g a lokala klimatförhållanden. I genomsnittsyns två områden med förhållandevis hög nederbörd — inre delarna av Södertörn ochnorra delarna av Norrtälje kommun. I dessa områden är nederbördsmängden nästandubbelt så stor som över de yttre delarna av skärgården, där de minsta mängderna förekommer.Som mest noteras drygt 900 mm nederbörd för det hydrologiska året 1994/95.Detta är ca. 30% högre än de genomsnittligt högsta värdena för 10 år (1984 — 1993).Den relativa geografiska fördelningen av årsnederbörden 1994/95 skiljer sig inte väsentligtfrån den genomsnittliga fördelningen under de senaste 10 åren.Den högsta våtdepositionen av svavel sker över Södertörn med drygt 6 kg S/ha/år. I yttreskärgården ligger värdena på omkring 3 till 4 kg/ha/år. För kväve är motsvarande siffrordrygt 7 kg N/ha/år respektive 4 kg N/ha/år. Den geografiska fördelningen av torrdepositionenbestäms i hög grad av var utsläppen sker. Beräkningarna visar på mycket skarpagradienter med den högsta torrdepositionen i Stockholmsregionen och lägre värden utmot landsbygden och skärgården. Högsta torrdepositionen av svavel och kväve beräknasuppgå till 5 kg S/ha/år respektive 7 kg N/ha/år, vilket är drygt hälften av den totala depositionen.Som mest uppgår den totala depositionen (summan av våt- och torrdepositionen) avsvavel och kväve till drygt 9 kg S/ha/år respektive 12 kg N/ha/år. Det lägsta nedfallet,som sker över landsbygdsområden och skärgården, är på knappt hälften av de högstavärdena. I hela länet överskrids de undre kritiska belastningsgränserna för både svaveloch kväve.Bidragen till nedfallet från utsläpp av kväve och svavel i Stockholms län har beräknatsmed hjälp av spridningsmodellen. För kväve kan drygt 50% av den totala depositionen iStorstockholm härledas till utsläppen i länet. För svavel är motsvarande siffra 30% —40%.- 5 -Utanför tätortsområdena har utsläppen inom länet endast liten betydelse för den totaladepositionen. Här står intransporterade svavel- och kväveföreningar för huvuddelen.Mätningarna visar att halterna i luften som transporteras in är jämnt fördelade över länet.De geografiska variationerna i depositionen över landsbygden och skärgården ärdärför dels beroende av nederbördens fördelning, som bestämmer variationen i våtdeposition,dels markanvändningen, som påverkar variationen i torrdeposition.Det enda säkra sättet att bedöma noggrannheten i beräkningarna är att så långt det gårjämföra beräknade halter, deposition och nederbörd med uppmätta värden (i vissapunkter). För nederbörden erhålls en god beskrivning på de flesta platserna. I genomsnittför 12 mätstationer är beräknad årsnederbörd inom 2% av uppmätt värde. Under sommarenkan dock avvikelserna bli stora p g a mycket stora variationer i nederbördsmängdernaför olika platser i länet.När det gäller kväveoxidhalter (NOx och NO2) erhålls en god överensstämmelse mellanberäkningar och mätningar i Stockholms innerstad. Beräknade månadsmedelvärden liggerför de flesta månaderna inom 20% av uppmätta värden. För svaveldioxidhalterna(SO2) är skillnaden större speciellt för sommarmånaderna då halterna är mycket låga.Beräknat totalt nedfall av svavel stämmer relativt väl med krondroppsmätningarna. Beräknattotalt nedfall av kväve kan däremot inte jämföras med kvävenedfallet i krondropp,eftersom träden tar upp en avsevärd del av det kväve som tillförs skogen via luftoch nederbörd.

On the Power of Quantum Computation: Oracles
- 2018
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Quantum computation solve some computational problems faster than the best-known alternative in classical computation. The evidence for this consists of examples where a quantum algorithm outperforms the best-known classical algorithm. A large body of these examples relies on oracle query complexity, where the performance (complexity) of the algorithms is measured by the number of times they need to access an oracle. Here, an oracle is usually considered to be a black box that computes a specific function at unit cost.However, the quantum algorithm is given access to an oracle with more structure than the classical algorithm. This thesis argues that the two oracles are so vastly different that comparing quantum and classical query complexity should not be considered evidence, but merely hints for a quantum advantage.The approach used is based on a model that can be seen as an approximation of quantum theory, but can be efficiently simulated on a classical computer. This model solves several oracular problems with the same performance as their quantum counterparts, showing that there is no genuine quantum advantage for these problems. This approach also clarifies the assumptions made in quantum computation, and which properties that can be seen as resources in these algorithms.

Knowledge, Product Differentiation and Trade
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this thesis is to analyze the influence of knowledge on the export performance of firms in different regions. More specifically, this study focuses on the impact of knowledge on the structure of regional export flows, in terms of horizontal and vertical product differentiation, as well as the geographical distribution of export flows. The thesis consists of four separate papers, which contribute to the overall analysis of knowledge, product differentiation and international trade in different ways. The second chapter presents a study of the effects of regional accessibility to R&D on the diversity of export flows with regard to goods, firms and destination markets. Chapter 3 provides an empirical analysis of vertical product differentiation, i.e. differentiation in terms of product quality, and examines the impact of educated labor and R&D on regional comparative advantages in goods of relatively high product quality. Chapter 4 contains a study of how the regional endowment of highly educated workers affects the structure of export flows, i.e. how the endowment of educated workers impacts on the number of product varieties exported, the average price per variety and the average quantity shipped out. The final chapter presents a micro-level analysis of firms’ propensity to participate in international markets and their propensity to expand export activities by introducing new export products or establishing export links with new destination countries. In summary, the empirical results of this thesis convey the message that regional accessibility to knowledge, embodied in highly educated labor and/or developed through R&D activities, plays a fundamental role in shaping the content and structure of regional export flows. More specifically, the present empirical observations suggest that the regional endowment of knowledge stimulates the size of the export base in terms of exporting firms and number of product varieties. The recurring significance of the accessibility variables in explaining spatial export patterns show that the knowledge endowment of a region must be defined in such ways that it captures sources of potential knowledge spillovers from inside as well as outside its own regional boundaries. This outcome shows that regional variations in knowledge endowments originate both in the actual spatial distribution of a nation’s knowledge labor across regions, and in regional differences in the geographical accessibility to internal and external knowledge labor.

Molecular oxygen in the rho Ophiuchi cloud
- 2007
-
Ingår i: Astronomy & Astrophysics. - : EDP Sciences. - 0004-6361 .- 1432-0746. ; 466:3, s. 5-
-
Tidskriftsartikel (refereegranskat)abstract
- Context: Molecular oxygen, O2, has been expected historically to be an abundant component of the chemical species in molecular clouds and, as such, an important coolant of the dense interstellar medium. However, a number of attempts from both ground and from space have failed to detect O2 emission.Aims: The work described here uses heterodyne spectroscopy from space to search for molecular oxygen in the interstellar medium. Methods: The Odin satellite carries a 1.1 m sub-millimeter dish and a dedicated 119 GHz receiver for the ground state line of O2. Starting in 2002, the star forming molecular cloud core ρ Oph A was observed with Odin for 34 days during several observing runs.Results: We detect a spectral line at v_LSR =+3.5 km s-1 with Δ v_FWHM=1.5 km s-1, parameters which are also common to other species associated with ρ Oph A. This feature is identified as the O2 (NJ = 11 - 1_0) transition at 118 750.343 MHz.Conclusions: The abundance of molecular oxygen, relative to H{2} , is 5 × 10-8 averaged over the Odin beam. This abundance is consistently lower than previously reported upper limits.Based on observations with Odin, a Swedish-led satellite project funded jointly by the Swedish National Space Board (SNSB), the Canadian Space Agency (CSA), the National Technology Agency of Finland (Tekes) and Centre National d'Étude Spatiale (CNES). The Swedish Space Corporation has been the industrial prime contractor and also is operating the satellite. Appendix A is only available in electronic form at http://www.aanda.org

Tidskriftsartikel (refereegranskat)abstract
- Implants integrated into bone have revolutionised the retention of total nasal prostheses. However, it may be difficult to identify available sites for placement of the implant after excision. In addition, it is ideal to minimise wide bony exposure after radiotherapy to avoid compromising the blood supply. In this paper we describe a technique for accurate placement of frontal bone and customised zygomatic implants using a computer-designed and fabricated surgical guide with a minimal access flap.
