Journey to the destination: a circular tourism economy : a training program for the hospitality industry to facilitate a transition towards increased circularity in the South Baltic Region
- 2019
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Being aware of the extent of the tourism industry and that it is ever growing, which is also encouraged in many individual countries by the national and regional governments, it is evident that the tourism industry is an essential target group for introducing circular concepts and implementing circular solutions. Yet, this sector has so far received little attention in the literature and initiatives on circularity.Circular Economy (CE) goes beyond “green” or “environmental”, it includes all aspects of a community and challenges us to create solutions that are completely different from what we are used to. It also invites us to open up and interact with other stakeholders and the general public.In your hands is the first training material in circular economy specifically developed for small to medium sized companies of the tourism industry in the South Baltic Region. It is a small but important step in the direction towards circularity and a wellbeing society. Through this work we have shown that despite cultural challenges and regional differences there is a shared, common interest in making tourism more sustainable and even to work together towards a transformation of the hospitality industry. This common vision has been stronger than the challenges we faced in making this work and this is what will ensure the continued growing awareness on circularity and its integration in different sectors in our communities. In this work we have featured some of the groundbreaking experts in this field, and some of the first good practices from our regions. They are all courageous pioneers in a field that with time will become the norm. In fact, in the 10th Annual Forum of the EU strategy for the Baltic Sea Region (12-13/6/2019, Gdansk, Poland), CE was highlighted as the pathway to reach prosperity and wellbeing in the Baltic Sea Region.

THE WAXHOLM APPLICATION DATABASE
- 1995
-
Konferensbidrag (refereegranskat)abstract
- This paper describes an application database collected in Wizard-of-Oz experiments in a spoken dialogue system, WAXHOLM. The system provides information on boat traffic in the Stockholm archipelago. The database consists of utterance-length speech files, their corressonding transcriptions, and log files of the dialogue sessions. In addition to the spontaneous dialogue speech, the material also comprise recordings of phonetically balanced reference sentences uttered by all 66 subjects. In the paper the recording procedure is described as well as some characteristics of the speech data and the dialogue.

An experimental dialog system: WAXHOLM
- 1993
-
Konferensbidrag (refereegranskat)abstract
- Recently we have begun to build the basic tools for a generic speech-dialogue system, WAXHOLM. The main modules, their function and internal communication have been specified. The different components are connected through a computer network. A preliminary version of the system has been tested, using simplified versions of the modules. We will give a general overview of the system and describe some of the components in more detail. Application specific data are collected with the help of Wizard-of-Oz techniques. The dialogue system is used during the data collection and the wizard only replaces the speechrecognition module.

- We demonstrate a prototype solar cell with a transparent polymer cathode, and indium-tin-oxide (ITO)/poly (3, 4-ethylene dioxythiophene)-poly (styrene sulphonate) (PEDOT:PSS) anode. As an active layer, thin film of a bulk heterojunction of polyfluorene copolymer poly[2,7-(9,9-dioctyl-fluorene)-alt-5,5-(4′,7′-di-2thienyl-2′,1′3′-benzothiadiazole)] (APFO-3) and an electron acceptor molecule [6] and [6]-phenyl-C61-butyric acid methyl ester (PCBM) (1:4 wt.) was sandwiched between the two transparent polymer electrodes. The cathode is another form of PEDOT formed by vapor phase polymerised PEDOT (VPP PEDOT) of conductivity 102–103 S/cm. The cathode is supported on an elastomeric substrate, and forms a conformal contact to the APFO-3/PCBM blend. Transparent solar cells are useful for building multilayer and tandem solar cells.

- In organic-based (opto)electronic devices, charge injection into conjugated materials is governed to a large extent by the metal-organic interface dipole. Controlling the injection of charges requires a better understanding of the fundamental origin of the interface dipole. In this context, photoelectron spectroscopies and density functional theory calculations are used to investigate the interaction between para-phenylenediamine (PPDA), an electron donor, and a polycrystalline nickel surface. The interface dipole formed upon chemisorption of one PPDA monolayer strongly modifies the work function of the nickel surface from 5.10 to 3.55 eV. The work function decrease of 1.55 eV is explained by the electron-donor character of PPDA and the modification of the electronic density at the metal surface. PPDA monolayers are composed of tilted molecules interacting via the nitrogen lone-pair and PPDA molecules chemisorbed parallel to the surface via their π-electron density. Annealing the monolayer leads to dehydrogenation of PPDA activated by the nickel surface, as found for other amines.

- Novel applications for flexible electronics, e.g., displays and solar cells, require fully flexible, transparent, stable, and low-work-function electrodes that can be manufactured via a low-cost process. Here, we demonstrate that surface chemistry constitutes a route to producing transparent low-work-function plastic electrodes. The work function of the conducting polymer poly(3,4-ethylenedioxythiophene)-tosylate, or PEDOT-Tos, is decreased by submonolayer surface redox reaction with a strong electron donor, tetrakis-(dimethylamino)ethylene (TDAE), allowing it to reach a work function of 3.8 eV. The interface formed between TDAE and PEDOT is investigated in a joint experimental and theoretical study using photoelectron spectroscopy and quantum chemical calculations. © 2006 American Chemical Society.

- BackgroundWith the development and refinement of techniques most mastectomy patients nowadays are candidates for breast reconstruction. No one surgical technique fits all, however. Treatment choices are driven by patient characteristics and preferences, alongside policy and operational factors. These, in turn, might be expected to differ on several levels of aggregation, for example, countries, regions, and hospitals. The aim of this study was to compare choices for breast reconstruction timing and modality in Uppsala (Sweden), Maastricht (the Netherlands), and Rome (Italy).MethodsIn this cross-sectional study, patients presenting for first-time post-mastectomy breast reconstruction in three teaching hospitals were included. The primary study outcomes were breast reconstruction timing and modality. Covariables were body habitus (i.e., body mass index, waist circumference, and mastectomy weight), health-related quality of life assessed with the BREAST-Q Reconstruction module, patient preferences assessed with a self-constructed questionnaire, and shared decision making assessed with the CollaboRATE questionnaire. Statistical tests were used to compare data across study sites.ResultsSixty-six participants were included. The most common choices for breast reconstruction timing and modality were delayed DIEP flaps in Uppsala (53%), immediate DIEP flaps in Maastricht (44%), and immediate prepectoral implants in Rome (92%). Participants in Rome were much slenderer than participants in Uppsala and Maastricht (mean body mass index 21.6, 26.2, and 26.3 kg/m2, respectively; p < 0.05). Participants in Uppsala and Maastricht highly valued material used for the reconstruction; participants in Rome were significantly more concerned with complications, scars, and recovery duration associated with the reconstruction.ConclusionsThis study shows large differences in choices for breast reconstruction timing and modality in Uppsala, Maastricht, and Rome. Possible reasons for the observed variation include differences in patient characteristics, patient preferences, reconstructive techniques available, and reimbursement.Level of evidenceLevel IV, Therapeutic study.

Tidskriftsartikel (refereegranskat)abstract
- Herein we assess the phylogenetic relationships and taxonomy of geckos of the genus Phyllodactylus inhabiting the peninsula of Baja California, Mexico using five mitochondrial and two nuclear genes. Phylogenetic analysis using maximum parsimony (MP) and Bayesian inference (BI) recovered three distinct peninsular clades with high statistical support. Sequence divergence estimates between peninsular taxa approached 13%. Two of the species, P. unctus and P. xanti are Cape Region endemics, whereas P. nocticolus is widespread throughout much of the peninsula and extreme southern California. Monophyly of the peninsular taxa was strongly supported. In the MP analysis, P. unctus rooted at the base of the peninsular clade, resolving P. xanti and P. nocticolus as sister taxa. Conversely, BI placed P. nocticolus and P. unctus as sister taxa. These data provide further evidence for a trans-peninsular seaway near the Isthmus of La Paz, severing the Cape Region from the rest of the peninsula. The analysis also supports the validity of P. nocticolus as a distinct species and suggests a single invasion to the peninsula from mainland Mexico, presumably during tectonic activity during the Miocene.

Tidskriftsartikel (refereegranskat)abstract
- Device function in organic electronics is critically governed by the transport of charge across interfaces of dissimilar materials. Accurate measurements of energy level positions in organic electronic devices are therefore necessary for assessing the viability of new materials and optimizing device performance. In contrast to established methods that are used in solution or vacuum environments, here we combine Kelvin probe measurements performed in ambient environments to obtain work function values with photoelectron spectroscopy in air to obtain ionization potential, so that a complete energy level diagram for organic semiconductors can be determined. We apply this new approach to study commonly used electron donor and acceptor materials in organic photovoltaics (OPV), including poly(3-hexylthiophene) (P3HT), [6,6]-phenyl C61 butyric acid methyl ester (PCBM), and ZnO, as well as examine new materials. Band alignments across the entire OPV devices are constructed and compared with actual device performance. The ability to determine interfacial electronic properties in the devices enables us to answer the outstanding question: why previous attempts to make OPV devices using 6,13-bis(triisopropylsilylethynyl) (TIPS)-pentacene as the electron donor were not successful.

- All-plastic light emitting diodes require the design and fabrication of low work function plastic electrodes. Here, we show that the work function of poly(3,4-ethylenedioxythiophene)-polystyrenesulfonic acid (PEDOT-PSS) can be decreased from 4.8 eV to 3.9 eV by surface reaction with the strong electron-donor tetrakis(dimethylamino)ethylene (TDAE). The surface modification was characterized by photoelectron spectroscopy and optical spectroscopy. The low work function plastic electrode was used in a first prototype for all-plastic light emitting diodes.

- OBJECTIVE: We sought to determine whether adipose tissue is inflamed in individuals with increased liver fat (LFAT) independently of obesity.RESEARCH DESIGN AND METHODS: A total of 20 nondiabetic, healthy, obese women were divided into normal and high LFAT groups based on their median LFAT level (2.3 +/- 0.3 vs. 14.4 +/- 2.9%). Surgical subcutaneous adipose tissue biopsies were studied using quantitative PCR, immunohistochemistry, and a lipidomics approach to search for putative mediators of insulin resistance and inflammation. The groups were matched for age and BMI. The high LFAT group had increased insulin (P = 0.0025) and lower HDL cholesterol (P = 0.02) concentrations.RESULTS: Expression levels of the macrophage marker CD68, the chemokines monocyte chemoattractant protein-1 and macrophage inflammatory protein-1alpha, and plasminogen activator inhibitor-1 were significantly increased, and those of peroxisome proliferator-activated receptor-gamma and adiponectin decreased in the high LFAT group. CD68 expression correlated with the number of macrophages and crown-like structures (multiple macrophages fused around dead adipocytes). Concentrations of 154 lipid species in adipose tissue revealed several differences between the groups, with the most striking being increased concentrations of triacylglycerols, particularly long chain, and ceramides, specifically Cer(d18:1/24:1) (P = 0.01), in the high LFAT group. Expression of sphingomyelinases SMPD1 and SMPD3 were also significantly increased in the high compared with normal LFAT group.CONCLUSIONS: Adipose tissue is infiltrated with macrophages, and its content of long-chain triacylglycerols and ceramides is increased in subjects with increased LFAT compared with equally obese subjects with normal LFAT content. Ceramides or their metabolites could contribute to adverse effects of long-chain fatty acids on insulin resistance and inflammation.

Deep biogeographical history and cytonuclear discordance in the black-tailed brush lizard

- Molecular tools help us deduce historical events such as vicariance, dispersal, gene flow and speciation. However, our inferences are inevitably linked to the nature of the characters that we use to infer history. For example, the difference in inheritance patterns of mitochondrial DNA (mtDNA) and nuclear DNA (non-recombining maternal vs. recombining biparental inheritance) may lead us to propose different intraspecific histories. The peninsula of Baja California of north-western Mexico, a region affected by a complex geological history involving temporary seaways, permits evaluation of differences between these character types. We sequenced 1966 bp of mtDNA to reconstruct the genealogical history of Urosaurus nigricaudus (black-tailed brush lizard) from samples spanning the entire peninsula. The genealogy revealed several deep divergences, congruent with temporary vicariance events in the mid-peninsular, Loreto and Cape regions, as well as a major split across the Isthmus of La Paz, possibly resulting from a late Miocene seaway. The results support an emerging picture of the historical biogeography of Baja California, which suggests that key vicariance events are older than commonly perceived. The maternal genealogy of U. nigricaudus sharply contrasts with variation in allozymes that suggests very little differentiation across mitochondrial breaks, consistent with a pattern of ongoing gene flow. We interpret this cytonuclear discordance in relation to the historical biogeography of the region.

Energy level alignment at metal-organic and organic-organic interfaces with Alq3 and NTCDA

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The energy level alignment behavior of the widely used materials tris-(8-hydroxyquinoline)aluminum (Alq3) and 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTCDA) is investigated. The Integer Charge Transfer (ICT) model is successfully used to predict their overall behavior at weakly-interacting hybridorganic and organic-organic interfaces, including NTCDA/Alq3 bilayers. The EICT- of NTCDA is measured to be 4.35 eV and the EICT+ of Alq3 is found to be 4.3 eV. The Alq3 films furthermore feature an interface dipole in absence of charge transfer due to the intrinsic dipole of the molecule and ordering effects.

- In organic-based electronics, interfacial properties have a profound impact on device performance. The lineup of energy levels is usually dependent on interface dipoles, which may arise from charge transfer reactions. In many applications, metal-organic junctions are prepared under ambient conditions, where direct overlap of the organic system from the metal bands is prevented due to presence of oxides and/or hydrocarbons. We present direct experimental and theoretical evidence showing that the interface energetic for such systems is governed by exchange of an integer amount of electrons.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Organic electronics is a field covering all applications and devices where one or several of the active components are made of organic material, such as organic light emitting diodes, organic solar cells, organic thin film transistors, organic magnets for spintronics etc. In all of the applications mentioned above, transport of charges across both inorganic/organic and organic/organic interfaces play a key role for device performance. In order to achieve high efficiencies and longer life-times, proper matching of the electronic energy levels of the different materials is needed.The aim of the research presented in this thesis has been to explore different routes to optimize interface energetics and gain deeper knowledge of the mechanisms that govern charge transport over the interface. Photoelectron spectroscopy (PES) is a method well suited to study both interactions between different materials taking place at surfaces as well as interface energetics.One way to achieve proper matching of interfaces energy levels is by adding a dipole layer. In the three first papers presented in the thesis, the method of adding a monolayer of small organic molecules to change the work function of the surface is investigated. We start with a model system consisting of a nickel surface and PPDA molecules where we have strong interaction and mixing of orbitals between the molecule and the metal surface. The second system consists of a gold surface and TDAE molecules with weaker interaction with integer electron transfer and finally in the third paper an organic surface VPP-PEDOT-Tos is modified, with TDAE, to create a transparent low work function organic electrode. In the fourth paper, we focus on gaining deeper understanding of the Integer Charge Transfer (ICT) model and the mechanisms governing the alignment of energy levels at organic/(in)organic interfaces and in the fifth paper we continue to challenge this model by using it to predict the behavior of a bilayer device, in terms of energy level alignment.

- Transparent low-work-function indium tin oxide (ITO) electrode was obtained by using molecular scale interface engineering. The modified ITO surface may be used as electron injecting electrode in polymer light-emitting devices. ITO surfaces, exposed to TDAE molecules, were found to be stable upon exposure to air, and to mild annealing. Photoelectron spectroscopy measurements show that the low-work-function of the modified electrode remains upon exposure to air in gentle annealing.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: High-quality leadership and chairing skills are central components in team performance during multidisciplinary team (MDT) meetings. We hypothesized that the recently developed A Tumor Leadership Assessment inStrument (ATLAS) could provide relevant information to support more detailed insights into MDT chairing and leadership aspects of relevance for team feedback and targeted improvements. Materials and Methods: The observational assessment instrument ATLAS rates chairing and leadership skills during MDT meetings in 12 predefined domains that include e.g. time management, case prioritization, team involvement, discussion climate and clarity of treatment recommendations. We used ATLAS to prospectively assess 33 MDT meetings in neuro-oncology, sarcoma and hepatobiliary cancer. Results: The aspects time management, effective case prioritization and provision of clear treatment plans were found to be well-functioning, whereas facilitatation of case discussions, encouragment of team member contributions, keeping the meeting focused and ability to summarize case discussions showed variable and partly weak results. Conclusion: We conclude that the ATLAS instrument effectively captures various aspects of MDT leadership and chairing skills. It may thereby provide relevant information to prioritize initiatives that support and develop effective teamwork and decision-making during MDT meetings.
