- The microstructure, phase and chemical composition of TixOy templates used to nucleate α-Al2O3 on Ti(C,N) coated cemented carbide have been elucidated using scanning electron microscopy, X-ray diffraction, Auger electron spectroscopy and Time-of-Flight Secondary Ion Mass Spectrometry. Further, the adhesive strength of the α-Al2O3–TixOy–Ti(C,N) interfaces was investigated using scratch adhesion testing.The present study confirmed that the as-deposited template consisted of a Ti4O7 phase which during subsequent deposition of the Al2O3 layer transformed to a Ti3O5 phase and that the grown Al2O3 layer consisted of 100% α-Al2O3. Furthermore, the results showed that the lowest interfacial strength within the multilayer structure was exhibited by the Ti(C,N)–TixOy interface and that the transformation of Ti4O7 to Ti3O5 in the template resulted in formation of pores in the Ti(C,N)-template interface lowering the interfacial strength even more. The use of surface analysis techniques such as Auger electron spectroscopy and especially Time-of-Flight Secondary Ion Mass Spectrometry enabled trace element analyses using depth profiling to characterise the thin interfacial layers in detail.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Ett hållbart och acceptabelt pensionssystem måste utformas utifrån personliga förutsättningar och förhållanden i arbetslivet, så att fler klarar att arbeta i högre ålder. Att enbart genom ekonomiska åtgärder höja pensionsåldern är inte långsiktigt hållbart, skriver 54 forskare.DEBATT | PENSIONForskning visar att cirka var fjärde har en diagnos eller skada orsakad av sitt arbete. Detta gör arbetsorsakad sjukdom och skada till ett betydelsefullt folkhälsoproblem. Att då enbart genom ekonomiska åtgärder höja pensionsåldern för samtliga (yrkes)grupper utifrån deras kronologiska ålder är inte långsiktigt hållbart när individers biologiska ålder är så olika bland annat till följd av arbetslivet. Detta är en demokratifråga. Forskning om äldre i arbetslivet och hållbart arbete visar att man då främst flyttar individer från pensionssystemet till sjukförsäkringssystemet och ökar klyftorna i samhället.Debatt Det här är en argumenterande text med syfte att påverka. Åsikterna som uttrycks är skribentens egna.Vi är 54 forskare som nu gemensamt har skrivit denna debattartikel. Anledningen är att vi är oroade över att cirka var fjärde blir sjuk av sitt arbete samtidigt som man i det förslag som ligger om att senarelägga ålderspensionen i princip utgår ifrån att arbetskraftsdeltagande enbart styrs av ekonomin. Vi vill trycka på betydelsen av åtgärder i arbetslivet för att komma tillrätta med ohälsan, det vill säga inte enbart ekonomiska restriktioner som tvingar folk som inte kan, vill och orkar att stanna kvar i arbetslivet till en högre kronologisk ålder.Pensionssystemet bygger på att vi ska arbeta en viss del av våra liv för att förtjäna möjligheter till pension. Vi bör dock inte enbart utgå ifrån antalet år sedan en person föddes, då korttidsutbildade generellt träder in på arbetsmarknaden tidigare än långtidsutbildade. De har alltså varit en del av arbetskraften från en yngre ålder. Människor med kortare utbildning har oftare ett arbete som innebär påfrestningar som kan inverka negativt på hälsotillståndet och som till och med kan påskynda det biologiska åldrandet. Dessutom lever korttidsutbildade generellt sett inte lika länge som långtidsutbildade, vilket delvis även avspeglar skilda livs- och arbetsvillkor.Den svenska sjukförsäkringsreformen 2008 avsåg att få tillbaka människor i arbete. Men studien fann att den faktiskt bidrog till att fler gick i tidig ålderspension av dem som var i åldern 55–64 år. Ökningen var störst bland korttidsutbildade. Mer än 5 procent fler gick i tidig ålderspension då det blev svårare att få sjukpenning och sjukersättning. Vi kan notera att det är vanligare att manliga chefer tar ut tidig ålderspension, jämfört med kvinnliga maskinskötare inom tillverkningsindustrin. I vissa yrken är det dessutom vanligare att människor, trots pension, både orkar och faktiskt ges möjlighet att arbeta vidare om de har en specialkompetens som efterfrågas. Om vi endast kombinerar ekonomiska morötter med piskor finns en stor risk att vi ökar klyftan mellan grupper som både kan och vill fortsätta att yrkesarbeta och personer som av olika skäl inte längre kan eller orkar.Ta nytta av den forskning som vi har tagit fram. Ett hållbart och acceptabelt pensionssystem måste utformas utifrån personliga förutsättningar och förhållanden i arbetslivet. Ett hållbart arbetsliv för allt fler i vår åldrande befolkning fordrar att vi samtidigt beaktar faktorer som relaterar till biologisk/kroppslig ålder, mental/kognitiv ålder samt social ålder/livsloppsfas och våra attityder som är kopplade till ålder. Vi måste ta större hänsyn till olika förutsättningar och varierande funktionsförmåga och utifrån detta anpassa de åtgärder som gör att arbetslivet blir möjligt och hållbart för allt fler även i högre ålder.”Morötter” är viktigare för en god arbetshälsa och hög produktivitet än en piska i form av oron för en dålig ekonomi.Forskning visar att pedagogik som bygger på ”morötter” oftast är betydligt bättre än ”piskor” för att nå framgångsrika och långsiktiga mål. ”Morötter” i samhället, för organisationer, företag och individer är därför viktiga för god arbetshälsa och fortsatt produktivitet och kan bidra till ett längre arbetsliv även för grupper som tidigare inte ens klarat av att arbeta fram till pensionsåldern. Genom forskning inom området har bland annat swage-modellen utarbetats. Detta är ett verktyg som visar på komplexiteten i ett hållbart arbetsliv och tillsammans med systematiskt arbetsmiljöarbete, handlingsplaner och åtgärder syftar till ett mer hållbart arbetsliv. Morötter är enligt forskningen i detta sammanhang åtgärder för en god fysisk och mental arbetsmiljö, avpassad arbetsbelastning, stödjande teknik, att man kan anpassa arbetstakten, alternativa arbetstidsmodeller vid behov. Det är viktigt att man känner sig trygg och förväntas och tillåts vara delaktig, att man blir sedd av chefen och arbetskamraterna. Att de egna arbetsuppgifterna upplevs som meningsfulla och behövda av andra skapar självförverkligande och tillfredsställelse i arbetet. Att man känner att ens arbetsuppgifter och man själv är viktig för organisationen och företaget. Att man trots högre ålder inkluderas i olika nysatsningar och får tillgång till kompetensutveckling och inte blir åsidosatt eller åldersdiskriminerad. Utvärderingar visar att de äldre medarbetarna som fick några av dessa anpassningar och möjligheter var mer effektiva, utvilade, stimulerade när de var på arbetet samtidigt som sjukfrånvaron minskade. Vilket i sin tur bidrar till ett längre arbetsliv för grupper som tidigare inte klarat av att arbeta fram till pensionsåldern. I organisationer som bygger på en deltagar- och lärandekultur rustas de anställda för att klara omställningar, nya arbetsuppgifter och vid behov även yrkesbyten.Med en åldrande befolkning där allt fler lever allt längre behöver vi arbeta till en högre ålder i framtiden för att pensionssystemet ska hålla. Men ”morötter” är viktigare för en god arbetshälsa och hög produktivitet än en piska i form av oron för en dålig ekonomi. Det kräver också att vi ändrar våra attityder och förhållningssätt till äldre på arbetsmarknaden, vilket vi bäst gör genom att organisationer och företag får incitament till och erbjuder mer individanpassade arbetsvillkor, särskilt för personer i högre ålder. Låt oss därför använda den framtagna kunskapen i praktiken för att göra arbetslivet friskt och hållbart för alla åldrar.

Vi är oroade över senare ålderspension

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Var fjärde person blir i dag sjuk till följd av sitt arbete. Att höja pensionsåldern för alla yrkesgrupper, utan konkreta åtgärder för att minska ohälsan, är därför problematiskt och mycket oroande. Det är, enligt forskarna, inte långsiktigt samhällsekonomiskt lönsamt att utan andra åtgärder höja pensionsåldern för alla. Vi – 54 forskare – är mycket oroade över konsekvenserna av att, som föreslagits, senarelägga ålderspensionen.Förslaget utgår i princip från arbetskraftsdeltagande i princip enbart styrs av ekonomin, medan forskningen visar att det bara är en av flera faktorer som styr hur länge och hur mycket människor väljer att arbeta.Det här sättet att lösa problemet med en åldrande befolkning och ett sviktande pensionssystem är inte samhällsekonomiskt lönsamt på lång sikt, utan riskerar bara att flytta runt folk mellan olika ersättningssystem. Pensionssystemet bygger på att vi ska arbeta en viss del av våra liv för att tjäna in vår pension. Vi bör dock inte enbart utgå ifrån ålder eller antalet år sedan en person föddes då korttidsutbildade generellt träder in på arbetsmarknaden tidigare än långtidsutbildade. De med kortare utbildningstid har alltså varit en del av arbetskraften från en yngre ålder. Människor med kortare utbildning har också oftare ett arbete som innebär påfrestningar som kan inverka negativt på hälsotillståndet och som till och med kan påskynda det biologiska åldrandet. Dessutom lever korttidsutbildade generellt sett inte lika länge som långtidsutbildade, vilket delvis även avspeglar skilda livs- och arbetsvillkor.Ta nytta av den forskning som vi har tagit fram. Ekonomin är självklart viktigt för att vi ska vilja arbeta, men den är som sagt enbart en av flera faktorer med betydelse vårt arbetsliv.Hälsotillståndet, både det fysiska och det mentala, har en avgörande betydelse för hur länge och hur mycket vi orkar arbeta. Ett fysiskt och mentalt belastande arbete är en stark riskfaktor för en nedsatt hälsa i slutet av arbetslivet. Arbetstid, arbetstakt och möjlighet till återhämtning spelar en allt större roll ju äldre vi blir. Andra aspekter är arbetsinnehåll, hur meningsfulla och stimulerande arbetsuppgifterna är, balansen mellan arbete och familjesituation och fritidsaktiviteter. Organisationskultur, ledarskapet, stöd i arbetet och kompetens har stor betydelse för om vi ska kunna och vilja arbeta till en högre ålder. Vi måste ta större hänsyn till olika förutsättningar och varierande funktionsförmåga och utifrån detta anpassa de åtgärder som gör att arbetslivet blir möjligt och hållbart för allt fler även i högre ålder.Ett hållbart och acceptabelt pensionssystem måste därför utformas utifrån personliga förutsättningar och förhållanden i arbetslivet. Ett hållbart arbetsliv för allt fler i vår åldrande befolkning fordrar att vi samtidigt beaktar faktorer som relaterar till biologisk/kroppslig ålder, mental/kognitiv ålder samt social ålder/livsloppsfas samt de attityder som är kopplade till ålder.

Contractile endothelin-B (ETB) receptors in human small bronchi
- 1996

Tidskriftsartikel (refereegranskat)abstract
- Endothelins (ETs) are a family of novel regulatory peptides and various lines of evidence suggest an important role for ETs in regulating pulmonary function. Two receptors for endothelin, ETA and ETB, have been found in the human lung, and according to recent studies a non-ETA receptor seems to mediate the contraction of large sized human bronchi. Several studies have emphasized the importance of small bronchi in the pathogenesis of airway disease. In the present paper, improved methodology was used which enables in vitro studies of small human bronchi down to a diameter of 0.5-1.0 mm. Using the new methodology we have tried to further characterize this receptor. Small bronchi from the distal parts of the bronchial tree were obtained from pulmonary tissue removed from 15 patients with lung cancer. They were dissected and cut into ring segments, in which isometric tension was recorded. ET-1, ET-2 and ET-3 elicited strong concentration-dependent contractions of the human small bronchus. Basically, the three peptides were equipotent with about the same maximal response. Upon reapplication, they all showed the same tachyphylaxis pattern, reaching half the initial contraction. Comparative analysis of IRL 1620, a selective ETB receptor agonist, revealed that the effect of the ETB agonist was, in all respects, similar to the responses induced by the ETs. PD 145065, a combined ETA/ETB receptor antagonist competitively inhibited the contractions induced by IRL 1620, whereas FR139317, a selective ETA receptor antagonist, was without effect. In conclusion, the present study shows that accurate measurements can be made in vitro on small human bronchi and all present data are in favour of an ETB receptor mediating endothelin-induced contraction of human bronchi smaller than 1.0 mm.

Energy efficiency potentials and energy management practices in Swedish firms
- 2012
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- In order to improve energy efficiency and reach the EU:s 20-20-20 primary energy saving target, focus has mainly been on diffusion of technology. Previous studies have illustrated large untapped energy saving potentials from implementing energy management practices in firms. Energy management practices have large effects on energy utilization and also a short pay-back time. According to these studies, energy management practices also effect investment decisions and the outcome of investments in energy efficient technologies. This paper investigates to what extent energy management practices influence firms estimation of energy efficiency potentials. Further it investigates two Swedish policy programs that promote industrial energy management practices: The Programme For improving Energy efficiency in energy-intensive industry (PFE) and the energy audit program and whether these have increased energy management practices in Swedish firms. A multiple case study has been conducted in order to investigate energy practices in firms in different industrial sectors. Employment of energy management varies between firms. The firms estimate equal energy efficiency potentials from implementation of energy efficient technology as for energy management practices. In total the firms estimate energy efficiency potentials of 12 %. The study shows that firms that have participated in the programs work more actively with energy management. This can be illustrated by the fact that 75 % of the firms that have not participated in any of the programs lack a person responsible for energy management and 50 % also lack a long term energy strategy. For firms that have participated in the programs the corresponding figures are 30 % and 33 %. The results indicate an untapped potential of energy efficiency measures that could be reached through increased energy management in Swedish industries.

Tidskriftsartikel (refereegranskat)abstract
- In order to reach the EU: s 20–20–20 primary energy savings target, energy efficiency needs to increase. Previous research on energy use and energy efficiency has focused mainly on the diffusion of energy efficient technologies. The discrepancy between optimal and actual implementation of energy efficient technologies has been illustrated in numerous articles and is often referred to as the energy efficiency gap. However, efficient technologies are not the only ways to increase energy efficiency. Empirical studies have found that a cost-effective way to improve energy efficiency is to combine investments in energy-efficient technologies with continuous energy management practices. By including energy management into an estimated energy efficiency potential this paper introduces an extended energy efficiency gap, mainly in manufacturing industries and the commercial sector. The inclusion of energy management components in future energy policy will play an important role if the energy savings targets for 2020, and later 2050, are to be met in the EU.

Arbetsgivares perspektiv på subventionerade anställningar : en kartläggning
- 2015
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Trots en kraftig ökning av antalet subventionerade anställningar från mitten av 2000-talet är det ett stort antal arbetsgivare som inte använder sig av lönesubventioner. Denna rapport har försökt att kartlägga och analysera arbetsgivares perspektiv på lönekostnadssubventioner. När det gäller analyser som berör de arbetsgivare som använt sig av lönesubventioner är den viktigaste förklaringsfaktorn att man använt sig av subventioner tidigare. Våra intervjuer visar också att de arbetsgivare som använder sig av lönesubventioner ofta har ett socialt ansvarstagande. Ett av huvudresultaten med följande studie är att 95 procent av de som använder sig av subventioner är nöjda. Omfattningen i pengar och personens kvalifikationer var mest avgörande för anställningsbeslutet. Av de som inte använt sig av lönesubventioner är det 20 procent som inte känt till att möjligheten finns. Intervjuer med arbetsgivare utan erfarenhet av att anställa med lönesubventioner visar att de är skeptiska att hitta lämplig personal genom att anställa med lönesubventioner. När vi ställer en hypotetisk fråga till samtliga arbetsgivare om vad som skulle kunna få dem att anställa med en subvention framkommer möjligheten att få pröva aktuell person som den klart viktigaste faktorn. Utifrån våra resultat föreslår vi bl.a. att Arbetsförmedlingen, i ett försöksupplägg, ska ges möjlighet att agera bemanningsföretag och vi föreslår också att man ska genomföra en omfattande informationskampanj till arbetsgivare.

Automatic in-line inspection of shape based on photogrammetry
- 2016
-
Ingår i: The 7th International Swedish Production Symposium, SPS16, Conference Proceedings. - Lund : Swedish Production Academy. ; , s. 1-9
-
Konferensbidrag (refereegranskat)abstract
- We are describing a fully automatic in-line shape inspection system for controlling the shape of moving objects on a conveyor belt. The shapes of the objects are measured using a full-field optical shape measurement method based on photogrammetry. The photogrammetry system consists of four cameras, a flash, and a triggering device. When an object to be measured arrives at a given position relative to the system, the flash and cameras are synchronously triggered to capture images of the moving object.From the captured images a point-cloud representing the measured shape is created. The point-cloud is then aligned to a CAD-model, which defines the nominal shape of the measured object, using a best-fit method and a feature-based alignment method. Deviations between the point-cloud and the CAD-model are computed giving the output of the inspection process. The computational time to create a point-cloud from the captured images is about 30 seconds and the computational time for the comparison with the CAD-model is about ten milliseconds. We report on recent progress with the shape inspection system.

Corrosion of copper in water free from molecular oxygen

Tidskriftsartikel (refereegranskat)abstract
- The possibility of copper reacting with O-2-free water has been investigated by analysis of primary corrosion products, as well as by monitoring gas pressure change by time, in long term experiments for up to 6 months in a glove box environment. We establish hydrogen production, but being of the same magnitude irrespective whether copper is present or not. Although low, the hydrogen production rate is considerably larger than what would directly correspond to the amount of analysed copper oxidation products. Our analyses encompass the changes to the surface cleaned copper (99.9999%), the water phase and the Duran glass in contact with the water (ppt quality). We have used very sensitive methods (XPS, AES, ICP-MS, XRF) while keeping contamination risks to a minimum. We conclude that the oxidation rate of copper is very low, yielding only parts of a monolayer of Cu2O after 6 months of exposure at 50 degrees C together with an accompanying very low concentration of copper species (4-5 mu g L-1) in the water phase.

Lack of evidence for estrogen and progesterone receptors in human adipose tissue.
- 1994

Tidskriftsartikel (refereegranskat)abstract
- We have previously presented data indicating the absence of estrogen and progesterone receptors from human adipose tissue by the use of specific antibodies (Abbott) as well as specific ligands. In addition, specific estrogen and progesterone cRNA probes did not hybridize to any mRNA species in either abdominal or gluteal/femoral adipose tissue as demonstrated by solution hybridization and Northern blot. In order to demonstrate even extremely small quantities of gene products we have now used the Polymerase chain reaction-technique to study estrogen- and progesterone receptor gene expression. Sequences corresponding to each specific cDNA were demonstrated indicating small amounts of estrogen- and progesterone receptor mRNA not detected by RNA/RNA or RNA/TNA (total nucleic acids) hybridization assays. The estrogen receptor-regulated gene pS2, however, was not induced by estrogens in human adipose tissue in contrast to a significant increase in pS2 mRNA levels after estrogen exposure to the estrogen receptor(+) cell line MCF7. From these results we conclude that estrogen- and progesterone receptors are absent from human adipose tissue and that the extremely low level of transcription of the corresponding genes is not sufficient to allow translation of the message into functional proteins.

Luminescence of silicon nanoparticles from oxygen implanted silicon
- 2018

Ingår i: Materials Science in Semiconductor Processing. - : Elsevier. - 1369-8001 .- 1873-4081. ; 86, s. 18-22
-
Tidskriftsartikel (refereegranskat)abstract
- Oxygen with a kinetic energy of 20 keV is implanted in a silicon wafer (100) at different fluences, followed by post-implantation thermal annealing (PIA) performed at temperatures ranging from 1000 to 1200 degrees C, in order to form luminescent silicon nanoparticles (SiNPs) and also to reduce the damage induced by the implantation. As a result of this procedure, a surface SiOx layer (with 0 < x < 2) with embedded crystalline Si nanoparticles has been created. The samples yield similar luminescence in terms of peak wavelength, lifetime, and absorption as recorded from SiNPs obtained by the more conventional method of implanting silicon into silicon dioxide. The oxygen implantation profile is characterized by elastic recoil detection (ERD) technique to obtain the excess concentration of Si in a presumed SiO2 environment. The physical structure of the implanted Si wafer is examined by grazing incidence X-ray diffraction (GIXRD). Photoluminescence (PL) techniques, including PL spectroscopy, time-resolved PL (TRPL), and photoluminescence excitation (PLE) spectroscopy are carried out in order to identify the PL origin. The results show that luminescent SiNPs are formed in a Si sample implanted by oxygen with a fluence of 2 x 10(17) atoms cm(-2) and PIA at 1000 degrees C. These SiNPs have a broad size range of 6-24 nm, as evaluated from the GIXRD result. Samples implanted at a lower fluence and/or annealed at higher temperature show only weak defect-related PL. With further optimization of the SiNP luminescence, the method may offer a simple route for integration of luminescent Si in mainstream semiconductor fabrication.

Consumer Behavior : classical and contemporary perspectives
- 2017. - 1
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Consumer Behavior: Classical and Contemporary Perspectives provides a basic understanding of the subject of consumer behavior. A better understanding in terms of why and how people consume is particularly relevant in today’s society since consumption has become an increasingly important part of people’s lives.This book differs from most previous textbooks by describing the subject of consumer behavior based on two comprehensive theoretical fields: theories concerning consumer psychology and decision-making, and theories concerning consumer culture and practices. These two perspectives complement one another and contribute to a better understanding of the complexity of consumption. Furthermore, the book has a sustainability perspective. The impact of consumption on the environment is important to highlight, not least with regard to future generations. The book also has a consumer perspective in that the consumer is not seen as a passive recipient of offers, but rather as an active actor who must be given the opportunity to make his or her voice heard. A better understanding of consumers’ different living conditions and the situations they encounter will give companies and other organizations a better chance to reach out to consumers and meet their needs.Consumer Behavior is also available in Swedish, published by Studentlitteratur.

Tidskriftsartikel (refereegranskat)abstract
- Global classification of the human proteins with regards to spatial expression patterns across organs and tissues is important for studies of human biology and disease. Here, we used a quantitative transcriptomics analysis (RNA-Seq) to classify the tissue-specific expression of genes across a representative set of all major human organs and tissues and combined this analysis with antibody- based profiling of the same tissues. To present the data, we launch a new version of the Human Protein Atlas that integrates RNA and protein expression data corresponding to 80% of the human protein-coding genes with access to the primary data for both the RNA and the protein analysis on an individual gene level. We present a classification of all human protein-coding genes with regards to tissue-specificity and spatial expression pattern. The integrative human expression map can be used as a starting point to explore the molecular constituents of the human body.

A NEXAFS and XPS study of oxygen doped Cu3N
- 2024

Ingår i: Journal of Physics D. - : IOP Publishing Ltd. - 0022-3727 .- 1361-6463.

Tidskriftsartikel (refereegranskat)abstract
- Thin films of pure and oxygen doped Cu3N, deposited by Chemical Vapour Deposition, have been studied with the NEXAFS technique both in the FLY and TEY mode and compared with XPS results. Cu, CuO and Cu2O have been used as reference samples in the investigation for detection of surface oxidation and contaminants. The aim has been to investigate how and if the chemical environment changes around Cu, N and O upon incorporation of oxygen in the Cu3N lattice. The recorded NEXAFS spectra are discussed in terms of valence electrons, crystal structure and local bonding environment. It was found that basically two oxygen absorption sites are possible in the crystal structure, (½, ½, 0) and (¼, ¼, ¼), and that the oxygen distribution between the two sites is probably given by the oxygen concentration.

Chemical Vapour Deposition of Undoped and Oxygen Doped Copper (I) Nitride
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In science and technology there is a steadily increased demand of new materials and new materials production processes since they create new application areas as well as improved production technology and economy. This thesis includes development and studies of a chemical vapour deposition (CVD) process for growth of thin films of the metastable material copper nitride, Cu3N, which is a semiconductor and decomposes at around 300 oC. The combination of these properties opens for a variety of applications ranging from solar cells to sensor and information technology. The CVD process developed is based on a metal-organic compound copper hexafluoroacetylacetonate, Cu(hfac)2 , ammonia and water and was working at about 300 oC and 5 Torr. It was found that a small amount of water in the vapour increased the growth rate considerably and that the phase content, film texture, chemical composition and morphology were strongly dependent on the deposition conditions. In-situ oxygen doping during the CVD of Cu3N to an amount of 9 atomic % could also be accomplished by increasing the water concentration in the vapour. Oxygen doping increases the band gap of the material as well as the electrical resistivity and changes the stability. The crystal structure of Cu3N is very open and contains several sites which can be used for doping. Different spectroscopic techniques like X-ray photoelectron spectroscopy, Raman spectroscopy and near edge X-ray absorption fine structure spectroscopy were used to identify the oxygen doping site(s) in Cu3N. Besides the properties, the oxygen doping also affected the morphology and texture of the films. By combining thin layers of different materials several properties can be optimized at the same time. It has been demonstrated in this thesis that multilayers, composed of alternating Cu3N and Cu2O layers, i.e. a metastable and a stable material, could be grown by CVD technique. However, the stacking sequence affected the texture, morphology and chemical composition. The interfaces between the different layers were sharp and no signs of decomposition of the initially deposited metastable Cu3N layer could be detected.

Tidskriftsartikel (refereegranskat)abstract
- Copper(I) nitride (Cu3N) is deposited by CVD using copper(II) hexafluoroacetylacetonate (Cu(hfaC)(2)), ammonia, and water as precursors. The influences of process parameters on growth rate, phase content, chemical composition and morphology are studied. The introduction of water is found to increase film growth rate on the SiO2 substrate. Films are deposited in the temperature range 250-550 degrees C. Single-phase Cu3N is obtained up to 400 degrees C. A phase mixture Of Cu3N and Cu is obtained at 425 degrees C, while a temperature of 550 degrees C and above yields single-phase Cu. X-ray diffraction (XRD) confirms that Cu3N has the cubic, anti-ReO3-type structure; with a cell parameter in the range 3.805-3.816 angstrom. X-ray photoelectron spectroscopy (XPS) verifies the Cu3N stoichiometry. The films are free from impurities (below the detection limit of 1%) at a large excess of ammonia. Scanning electron microscopy (SEM) shows facetted grains, with the faces becoming more well-defined at higher temperatures.

Deposition and characterisation of Cu2O/Cu3N multilayers
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Multilayers of Cu2O and Cu3N were successfully deposited by the CVD technique on SiO2 substrates. For deposition of the Cu3N layers Cu(hfac)2 and NH3 and for the Cu2O layers Cu(hfac)2 and H2O were used as precursors, respectively. The multilayers were deposited at 300 °C with different stacking sequences, starting with either the oxide or the nitride. In order to analyze and determine phase, texture, chemical composition and microstructure, the films were characterized by XRD, XPS and SEM. Results from GI-XRD measurements at different incidence angles show distinct Cu2O and Cu3N layers. No contaminations in the form of carbon or fluorine originating from the MO precursor were found by XPS technique. The XPS results also reveal that the Cu3N phase contained oxygen (for the Cu2O on top of Cu3N). The oxygen is expected to originate from exposure of the Cu3N surface to water vapour upon starting the Cu2O deposition. The cross section microstructure was studied by SEM. It was found that columnar growth occurred for both Cu2O/Cu3N and Cu3N/Cu2O/Cu3N films.

Tidskriftsartikel (refereegranskat)abstract
- A growth stability diagram for the system Cu-N-O has been determined in the temperature range 250-500°C for a thermally activated CVD process, based on copper (II) hexafluoroacetylacetonate (Cu(hfac)2), NH3 and H2O. Without any addition of water only Cu3N was obtained. Addition of water introduces oxygen into the Cu3N structure to a maximum amount of 9 atomic % at a water/nitrogen molar ratio of 0.36 at 325 °C. Above this molar ratio Cu2O starts to deposit in addition to an oxygen doped Cu3N phase. Only Cu2O is deposited at a large excess of water. XPS and Raman spectroscopy indicated that the additional oxygen in the doped Cu3N structure occupies an interstitial position with a chemical environment similar to oxygen in Cu2O. The oxygen doping of the Cu3N phase did not influence the lattice parameter which was close to the bulk parameter of 3.814 Å. The film morphology varied markedly with both deposition temperature and water concentration in the vapour during deposition. Increasing the water concentration results in less faceted and textured films with smoother and more sphere like grains. The resistivity of the Cu3N films increased with increased oxygen content of the film and varied between 10-100 Ωcm (0 to 9 atomic% O). The optical band gap increased from 1.25 to 1.45 eV as the oxygen content increased (0 to 9 atomic %).

Tidskriftsartikel (refereegranskat)abstract
- N-doped TiO2 thin films were prepared using pulsed laser deposition by ablating metallic Ti target with pulses of 248 nm wavelength, at 330 °C substrate temperature in reactive atmospheres of N2/O2 gas mixtures. These films were characterized by spectroscopic ellipsometry, X-ray photoelectron spectroscopy and X-ray diffraction. Optical properties are presented as a function of the N2 content in the processing gas mixture and correlated to nitrogen incorporation into the deposited layers. The optical band gap values decreased with increasing N concentration in the films, while a monotonically increasing tendency and a maximum can be observed in case of extinction coefficient and refractive index, respectively. It is also shown that the amount of substitutional N can be increased up to 7.7 at.%, but the higher dopant concentration inhibits the crystallization of the samples.

Market-Shaping as Meta-Strategy : A Strategy of Strategies
- 2023
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Markets are increasingly perceived as malleable systems constituted by actors that endogenously generate and shape the market. This view extends the traditional market view beyond the buyer-seller dyad and encompasses both directly market-related actors such as companies, suppliers, and buyers but also nonmarket actors such as regulators, lobbyists, journalists, activists, and the wider public. This alternative view has led to the emergence of market-shaping strategies, which refer to a focal company’s deliberate efforts to alter market characteristics, such as price levels or nonmarket elements, such as regulations, in its favor. Most descriptions of market-shaping strategies suggest that they influence both the market and nonmarket environments synergistically, and thus resemble the concept of an integrated strategy. However, given the systemic nature of markets, a company shaping a market may need to combine intended actions aimed at realizing the focal company’s market-shaping vision and emergent actions as response to emerging system dynamics. This implies that a market-shaping strategy may be constituted by different strategies with different but synergistic goals unified by the overarching goal of realizing the focal company’s market-shaping goal. In other words, a market-shaping strategy may be a strategy of strategies – a meta-strategy. Moreover, previous research has indicated the significant potential of market-shaping strategies to improve the financial performance of companies as well as the overall market performance by increasing market size, market growth and value creation. However, despite this potential, the notion of market-shaping strategies has remained conceptually and empirically underdeveloped. This dissertation seeks to improve our understanding of market-shaping strategies by analyzing the constituent dimensions of market-shaping strategies and by presenting new empirical insights into how such strategies are employed. Hereby, two papers synthesize extant literature on market-shaping to analyze and conceptualize the underlying process of market-shaping strategies as well as a typology of distinct market-shaping strategies. The other two papers provide new empirical evidence concerning the employment of market-shaping strategies by investigating the influence of market-shaping roles and capabilities on the market-shaping efforts of a focal company. Drawing on the findings in the appended papers, this dissertation examines market-shaping strategies from the perspective of a market, nonmarket, integrated, and meta-strategy to reduce the concept’s theoretical and conceptual ambiguity and enhance our conceptual and empirical knowledge of how market-shaping strategies are construed and employed. This dissertation proposes market-shaping to be a meta-strategy of different integrated strategies focused on shaping both the market and nonmarket environment, while mitigating system dynamics and pursuing the overarching goal of shaping a market. This meta-strategic perspective provides a more nuanced and structured approach to understanding market-shaping strategies, reducing ambiguity, and emphasizing the interrelations between different environments and strategies. Through this structured approach, the interrelations between the different environments and strategies are emphasized, rendering dynamics and synergies between the two more comprehensible and highlighting the necessity for systemic strategies. Thereby, this dissertation contributes to the literature on market shaping by providing a more detailed understanding of the nature and dimensions of market-shaping strategies, and how such strategies are employed by companies in practice. Through this effort, several theoretical and managerial implications are proposed as well as policy implications suggested that indicate a potential dark side of market-shaping strategies.

Tidskriftsartikel (refereegranskat)abstract
- This study explores the potential existence of reoccurring patterns in market-shaping processes by employing a qualitative meta-analysis to analyze 79 case studies on market-shaping. Through the evidence-based synthesis of qualitative data, we extract 20 generalized market-shaping activities that inform and form the foundation of a three-phased market-shaping process. This conceptual framework divides the market-shaping process into the phases of infusion, formation and retention. By applying our conceptual framework to the qualitative dataset, we explore the presence of market-shaping phases and provide further insights into the interdependences and dynamics between multiple, simultaneously occurring, market-shaping processes. By providing a structured market-shaping process, we attempt to reduce the overall complexity of the market-shaping phenomenon and facilitate the operationalization of the phenomenon for further market-shaping research. Additionally, our conceptualization provides practitioners with a framework to analyze the market-shaping efforts of other market actors and support the design of their own market-shaping strategies.

Market-shaping roles - Exploring actor roles in the shaping of the Swedish market for liquefied gas
- 2022

Tidskriftsartikel (refereegranskat)abstract
- Despite the emphasis on actors in the market-shaping literature, the market-shaping roles and heterogeneity of market actors have mostly been aggregated into overarching practices, processes, or activities. While market-shaping research has provided rich insights into the different activities, and actors, that play a role in shaping markets, it remains unclear how the differences in market actors market-shaping engagement translate back into specific roles. By following the Swedish market for liquefied gas over a period of three years, this longitudinal case study draws on extensive data to further elucidate market-shaping processes through the lens of roles. Employing an abductive theorizing approach, we empirically investigate the different roles performed by market actors in market-shaping processes. We discover that roles depend on the different levels in market-shaping engagement towards a focal market vision that ultimately relates to the disposition, behavior and influence displayed by the specific actors. Within this process we identify and delineate six market-shaping roles: the Market Driver, Market Supporter, Market Missionary, Market Rival, Market Catalyzer, and Market Detractor.

Market-shaping strategies : A conceptual framework for generating market outcomes
- 2021

Ingår i: Industrial Marketing Management. - : Elsevier. - 0019-8501 .- 1873-2062. ; 96, s. 254-266
-
Tidskriftsartikel (refereegranskat)abstract
- We identify four market-shaping strategies and their related activities that enable a focal market actor to work towards specific market outcomes. The conceptual framework provides firms with a tool for choosing specific market-shaping strategies depending on their market-shaping intention (offensive/defensive) and perception of a market's stability (stable/unstable). Accordingly, and in line with market-shaping literature, the four market-shaping strategies enable a firm to widen, reduce, maintain, or disrupt a market. Whereas previous market-strategy conceptualizations emphasized firm-level outcomes, the four identified market-shaping strategies focus on market outcomes and encompass a more comprehensive understanding of the impact of a firm's strategic actions on a market. Thereby, this study offers new perspectives on the implementation of market strategies in the context of markets as complex adaptive systems. By exemplifying the four market-shaping strategies using four industry cases, we illustrate how market-shaping strategies can appear in practice and demonstrate how firms can strategically leverage and steer market processes to their advantage.

Green Service Innovation : The role of resource integration and service provision
- 2014
-
Ingår i: Proceedings of the 2014 AMA SERVSIG International Service Research Conference. - 9789609874090
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Purpose: The importance of green services is increasing. The purpose of the research project is to develop a better understanding of the concept “green services” and its relationship to “service innovation”. The research questions are: What factors can define the green services concept? What are the distinctive characteristics of different types of green services? Methodology: A multiple case study approach is used. The cases represent companies having introduced green service innovations. Based on interviews with the innovators and customers different categories of green services are indentified and described. The empirical findings are then analyzed in the light of a literature review. Findings: By combining empirical observations and theory the authors develop a framework for green service innovations. This framework describes how innovation can be attained through emphasizing changes in resource integration (reuse waste, reduce impact on nature and improve nature) and service provision (direct service or indirect service). In this frame six categories of green services are defined: redistribution of resources, changing customer behavior, improving conditions for nature, upcycling, replacement of technology and products to improve nature.Originality/value: The majority of existing research on green service has had focus on the service companies and the change of technology in providing services. The authors here rather emphasize the customer roles, and stresses that these roles need to change to fulfill green service innovation. Moreover, the perspective here is that green services have the ability to not only mitigate negative impact on the environment but also increase the quality of nature. The term “greenovation” is proposed to emphase this.

Konferensbidrag (refereegranskat)abstract
- This paper presents a typology for green service. It is based on two dimensions: a resource integration dimension to differentiate between different efforts aiming to reduce, reuse, redistribute, recycle or renew resources (for instance natural or operant resources); and a dimension representing whether other ecosystem actors are actively or passively involvement in the green service. The ten types of green service provide an analytical tool for service marketing managers and scholars discussing how to improve or develop green service.

Identifying the resource integration processes of green service
- 2019
-
Ingår i: Journal of Service Management. - : Emerald Group Publishing Limited. - 1757-5818 .- 1757-5826. ; 31:4
-
Tidskriftsartikel (refereegranskat)abstract
- Purpose: The purpose of this paper is to improve the understanding of green service. In particular, the focus is on identifying homopathic and heteropathic resource integration processes that preserve or increase the resourceness of the natural ecosystem. Design/methodology/approach: Through an extensive multiple case study involving ten service providers from diverse sectors based on a substantial number of interviews, detailed accounts of green service are provided. Findings: Six resource integration processes were identified: reducing, recirculating, recycling, redistributing, reframing and renewing. While four of these processes are based on homopathic resource integration, both reframing and renewing are based on heteropathic resource integration. While homopathic processes historically constitute a green service by mitigating the impact of consumption on the environment, heteropathic resource integration increases the resourceness of the natural ecosystem through emergent processes and the (re)creation of natural resources. Research limitations/implications: The present study breaks away from the paradigm that “green service” is about reducing the negative environmental impact of existing services, toward providing a green service that expands biological diversity and other natural resources. Originality/value: Transformative service research on environmental sustainability is still in its infancy. The present study contributes through conceptualizing green service, redefining existing resource integration processes (reducing, recirculating, recycling) and identifying new resource integration processes (redistributing, reframing, renewing).

Marketing and sustainability : why and how sustainability is changing current marketing practices
- 2020. - 1
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- This book aims to equip business students and marketing practitioners with a thorough understanding of sustainability issues. It uses contemporary cases and useful conceptualizations from recent research to provide a toolbox that help the reader understand how to deliver value to today’s consumers, while considering the well-being of future generations.Marketing & Sustainability raises important questions concerning the impact of (over)consumption, production, distribution, and communication, all key marketing activities, on socio-environmental challenges in the world — such as climate change and natural resource depletion.Servitization, dematerialization of consumption, the emergence of the circular economy paradigm, the platform-based sharing economy paradigm and the use of sharing schemes and platform-based exchanges of existing market goods are all dealt with in this book, which will make a lot of sense for students, marketers and other professionals who are aware of and striving for sustainable growth.

The Heart and Wallet Paradox of Collaborative Consumption
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Collaborative consumption is a peer-to-peer (P2P) exchange of goods and services facilitated by online platforms. This phenomenon is driven by technologies that make it easier and cheaper to redistribute and share the use of existing but underutilized private resources. It is embedded in the paradigm shift in society towards access-based consumption, in opposition to acquisition and private individual ownership. Firms take on the new role of enabler of collaborative consumption by developing online platforms and smartphone apps that facilitate P2P exchanges between people in their roles of peer providers and consumers.Collaborative consumption is anchored to two opposite logics of consumption: sharing and market exchange. This results in the Heart & Wallet paradox with its tensions between a pro-social orientation and communal norms on the one hand, and a for-profit orientation and market norms on the other hand. While diverse societal and regulatory aspects of the so-called “sharing economy” are discussed in popular debate, scholars have yet to catch up on the theoretical implications from these influences on business activities and consumer behavior.This thesis aims to improve the understanding of collaborative consumption by contributing to the conceptualization of this new phenomenon as intertwined with coexisting sharing and market logics. The research is based on two papers taking the perspective of the firms operating online platforms that facilitate collaborative consumption, and two papers taking the perspective of the peer providers and consumers participating in P2P exchanges. The context of shared mobility (i.e. P2P car rental, ridesharing) is explored through three cases, using interviews with online platform managers and participants in collaborative consumption, participant observation, a netnography, a cross-sectional survey of platform users, and document analyses.This thesis situates collaborative consumption in the access paradigm, based on the temporal redistribution and monetization of private resources facilitated via online platforms, while nurturing the feelings of communal belonging and the sharing ethos embedded in P2P exchanges. Investigating the tensions of the Heart & Wallet paradox of collaborative consumption, I highlight the opposing rationales between the sharing logic of the original nonmonetary practices initiated by grassroots communities and the market logic of platform business models. I further emphasize the key function of communal identification for participants and the role of perceived sharing authenticity—the pitfalls of sharewashing for firms. This thesis contributes to service research by advancing the understanding of P2P exchanges and the conceptualization of collaborative consumption.

Tidskriftsartikel (refereegranskat)abstract
- Retailers are the gatekeepers between consumers and eco-friendly products. As such, they can influence green shopping behavior. The results of an eye-tracking experiment show that retailers can attract consumers’ visual attention and increase the green premium through various practices such as providing relevant information, orienting consumers inside the store, and offering an eco-friendly product assortment. Managerial implications are to use green-colored price tags to signal eco-friendly products, while avoiding greenwashing practices that can distract consumers from finding the eco-friendly products they look for.

BEST: Bypass equipoise sleeve trial; rationale and design of a randomized, registry-based, multicenter trial comparing Roux-en-Y gastric bypass with sleeve gastrectomy
- 2019
-
Ingår i: Contemporary Clinical Trials. - : Elsevier BV. - 1551-7144 .- 1559-2030. ; 84
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Laparoscopic gastric bypass (LGBP) is a well-documented surgical intervention for severe obesity. Recently, laparoscopic sleeve gastrectomy (LSG) has gained increased popularity. Short-term follow-up in limited-sized randomized trials comparing LGBP and LSG show no major differences in weight-loss, adverse events, or effect on comorbidities; however, there is a lack of sufficiently powered, pragmatic, randomized controlled trials comparing the mid- and long-term results of the two methods. Method: BEST is a randomized, registry-based, multicenter trial comparing LGBP and LSG. The trial has two primary outcomes; rates of substantial complications (SC) and total body weight loss. We hypothesize that patients treated with LSG will experience 35% fewer substantial complications during the 5-year follow-up compared to patients treated with LGBP, and that the efficacy of LSG will remain within a non-inferiority margin of 5% in terms of weight loss. Our sample size calculation, using data from the Scandinavian Obesity Surgery Registry (SOReg), shows a power of 80% for SC and > 95% for weight loss at p < .025 with a total of 2100 included patients. The design of the trial will also enable comparisons within several relevant patient subgroups. Conclusions: As a large-sized, pragmatic, randomized trial, BEST will provide robust data comparing LGBP with LSG by generating long-term results on weight loss and SC's, as well as secondary outcomes and comparisons within patient subgroups. The use of a well-established registry for registration of all data facilitates a large multicenter trial, and combines the strengths of registry studies with those of a randomized trial.

Tidskriftsartikel (refereegranskat)abstract
- IMPORTANCE: Laparoscopic sleeve gastrectomy (SG) and laparoscopic Roux-en-Y gastric bypass (RYGB) are widely used bariatric procedures for which comparative efficacy and safety remain unclear.OBJECTIVE: To compare perioperative outcomes in SG and RYGB.DESIGN, SETTING, AND PARTICIPANTS: In this registry-based, multicenter randomized clinical trial (Bypass Equipoise Sleeve Trial), baseline and perioperative data for patients undergoing bariatric surgery from October 6, 2015, to March 31, 2022, were analyzed. Patients were from university, regional, county, and private hospitals in Sweden (n = 20) and Norway (n = 3). Adults (aged ≥18 years) eligible for bariatric surgery with body mass indexes (BMIs; calculated as weight in kilograms divided by height in meters squared) of 35 to 50 were studied.INTERVENTIONS: Laparoscopic SG or RYGB.MAIN OUTCOMES AND MEASURES: Perioperative complications were analyzed as all adverse events and serious adverse events (Clavien-Dindo grade >IIIb). Ninety-day mortality was also assessed.RESULTS: A total of 1735 of 14 182 eligible patients (12%; 1282 [73.9%] female; mean (SD) age, 42.9 [11.1] years; mean [SD] BMI, 40.8 [3.7]) were included in the study. Patients were randomized and underwent SG (n = 878) or RYGB (n = 857). The mean (SD) operating time was shorter in those undergoing SG vs RYGB (47 [18] vs 68 [25] minutes; P < .001). The median (IQR) postoperative hospital stay was 1 (1-1) day in both groups. The 30-day readmission rate was 3.1% after SG and 4.0% after RYGB (P = .33). There was no 90-day mortality. The 30-day incidence of any adverse event was 40 (4.6%) and 54 (6.3%) in the SG and RYGB groups, respectively (odds ratio, 0.71; 95% CI, 0.47-1.08; P = .11). Corresponding figures for serious adverse events were 15 (1.7%) for the SG group and 23 (2.7%) for the RYGB group (odds ratio, 0.63; 95% CI, 0.33-1.22; P = .19).CONCLUSIONS AND RELEVANCE: This randomized clinical trial of 1735 patients undergoing primary bariatric surgery found that both SG and RYGB were performed with a low perioperative risk without clinically significant differences between groups.TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02767505.
