    25 years of studying New Public Management: accomplishments and limitations2020Ingår i: Financial Accountability and Management, ISSN 0267-4424, E-ISSN 1468-0408, Vol. 36, nr 1Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In 1991, Christopher Hood made a substantial contribution to public administration research when he formulated the concept of New Public Management (NPM). His article can in many ways be understood as an enabler of research focused on public sector reforms. To this day, numerous articles and books have been published, discussing the concept itself and the empirical phenomenon. In celebration of the 25-year period since the concept of NPM was introduced, this article revisits the current knowledge through a systematic literature review of 299 articles published between 1991 and 2016. This approach enables a meta-analysis of research published in five top-ranked international public administration journals. We identify four important themes as emerging from our review: (i) a reform with a vague intention, (ii) the limping concept, (iii) the one-sided perspective and (iv) NPM as the new norm. An important effect of this is that Hood’s framework may have been curtailed, leading to a distorted knowledge base when it comes to future studies.

    Hur ser tysk L2-produktion ut hos svenska, kinesiska och vitryska avancerade inlärare?2020Ingår i: European Journal of Scandinavian Studies, ISSN 2191-9399, E-ISSN 2191-9402, European Journal of Scandinavian Studies, ISSN 2191-9399Artikel i tidskrift (Refereegranskat)
    Abstract [sv]

    I denna artikel presenteras en delstudie som genomförts inom det tyska nätverket Kobalt-DaF (Deutsch als Fremdspache), där tio forskare inom andraspråksinlärning (L2) och korpuslingvistik analyserade tyska texter (L2) producerade av   inlärare med svenska, kinesiska och vitryska som modersmål (L1). Här presenteras den delanalys som gjordes av fundamentet (Vorfeld) i påståendesatser. Tidigare studier visar att L2-inlärare transfererar inte bara syntax utan även språkspecifika informationsstrukturella mönster. De informationsstrukturella preferenser man har i sitt L1 avspeglar sig på det L2 man lär sig. Även denna studie bekräftar transfer av språkspecifik informationsstrukturering.

     Trots att svenska och tyska båda är germanska språk och de språk som här är närmast besläktade uppvisar mot förmodan de kinesiska informanternas L2-texter informationsstrukturella frekvenser som ligger närmast den tyska kontrollkorpusen. Även om ryska och svenska är typologiskt olika språk, föredrar båda att placera ny information senare i satser. Detta mönster med placering av konstituenter med lågt informationsvärde i fundamentet avspeglar sig också i dessa informanters L2-texter, som därmed uppvisar liknande satsdelsfrekvenser i fundamentet.

    Towards Autonomous Shipping: Exploring Potential Threats and Opportunities in Future Maritime Operations2020Ingår i: Advances in Human Factors of Transportation: Proceedings of the AHFE 2019 International Conference on Human Factors in Transportation, July 24-28, 2019, Washington D.C., USA / [ed] Neville Stanton, Springer, 2020, s. 633-644Konferensbidrag (Refereegranskat)
    Abstract [en]

    This article presents findings from an ongoing research project aiming to study the future of shipping operations with a specific focus on issues related to human roles, responsibilities and the organization of work. A focus group with representatives for the Swedish shipping cluster (n = 6) and academia (n = 2) has been conducted to explore potential strengths, weaknesses, opportunities and threats (SWOT) with the developments towards autonomous shipping. The results show an overall concern for how to realize the transition between today’s maritime traffic and a future setting where vessels may be operated from shore. Technology to automate navigational tasks and increase the degree of autonomy in shipping are developing, but more attention needs to be paid to the transition of work that may accompany the ongoing developments. Clear roles, responsibili- ties and a definition of potential operator competences need to be formulated to ensure a human-centered development for safer shipping.

    A 3D model for knots and related fiber deviations in sawn timber for prediction of mechanical properties of boards2019Ingår i: Materials & design, ISSN 0264-1275, E-ISSN 1873-4197, Vol. 166, s. 1-18, artikel-id 107617Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Increased use of wood has led to complex timber constructions and new types of engineered wood products. In simulations, however, mainly simplified models are used to describe this material with its strongly varying properties. Therefore, reliable prediction tools for mechanical properties of wooden boards are needed. Those varying properties mainly originate from knots and fiber deviations. Thus, we use fiber directions on board surfaces to reconstruct knots within boards. Combined with a fiber deviation model we assess our model with experiments on different levels: fiber directions on surfaces, strain fields and bending stiffness profiles.

    This model now better describes fiber patterns near knots and knot clusters. Also, we showed that accurate modeling of the pith is important to avoid large regions of incorrect fiber deviations. Furthermore, modified knot stiffness properties were successfully used to consider pre-cracked knots. Finally, we obtained multiple bending stiffness profiles, where we showed that even local effects can be simulated accurately.

    We anticipate our tool to be a starting point for improving strength grading models, where effects of knot configurations can be studied more easily than with experiments alone. Furthermore, the presented improvements will render the simulation of realistic failure mechanisms in wooden boards more likely.

    A business model typology for destination management organizations2019Ingår i: Tourism Review, ISSN 1660-5373, E-ISSN 1759-8451Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose

    The need and legitimacy of destination management organizations (DMOs) are increasingly questioned. Still, the tourism literature provides little advice on how DMOs change and finance their activities for the benefit of their destination-given contextual change. This conceptual article aims to contribute to filling this gap. The authors do so by proposing a typology of business models for destination management organizations.

    Design/methodology/approach

    With the help of typological reasoning, the authors develop a new framework of DMO business model ideal types. To this end, the authors draw on extant literature on business model typologies and identify key dimensions of DMO business models from the tourism literature.

    Findings

    The challenges DMOs face, as discussed in the tourism literature, relate to both ends of their business model: On the one end, the value creation side, the perceived value of the activities they traditionally pursue has been declining; on the other end, the value capture side, revenue streams are less plentiful or attached to more extensive demands. On the basis of two dimensions, configurational complexity and perceived control, the authors identify four distinct ideal types of DMO business models: the destination factory, destination service center, value orchestrator and value enabler.

    Originality/value

    The authors outline a “traditional” DMO business model that stands in contrast to existing DMO classifications and that relates DMO challenges to the business model concept. The typology provides an integrated description of how DMO business models may be positioned to create and capture value for the organization and the destination(s) it serves. The ideal types point to important interdependencies of specific business model design choices.

    A cell glue: Inducing cell adhesion using surface modification with cell-penetrating peptide-peg-lipid for 3d cell structures2019Ingår i: Transactions of the Annual Meeting of the Society for Biomaterials and the Annual International Biomaterials Symposium, Society for Biomaterials , 2019Konferensbidrag (Refereegranskat)
    Abstract [en]

    Statement of Purpose: The ultimate goal of regenerative therapy is the transplantation of functional stem cells-derived tissues and organs to replace those lost as the result of pathology or tissue damage. Since tissues and organs are complicated 3D structures, 3D scaffolds such as decellularized organs and tissues, are required to properly orient living functional cells of different types. 3D scaffolds offer an environment for cell adhesion that differs from that of conventional 2D culture. Therefore, the induction and control of cell attachment, not only to 2D substrate surfaces but also to 3D scaffolds, is of great importance. Here, we propose new type of cell glue made of cell-penetrating peptides (CPP) and PEG-conjugated lipid, which are used for cell-surface modification. PEG-lipid derivatives are incorporated into the lipid bilayer membranes of cells via hydrophobic interactions, and the CPP anchored onto the cell membrane could work as an adhesive domain. In our study, various floating cells, (i.e., T cells, B cells) were used to examine the adhesive efficacy by cell surface modification with CPP-PEG-lipid onto material surface as well as PS microfiber-based 3D scaffolds. © 2019 Omnipress - All rights reserved.

    A classical test theory evaluation of the Sleep Condition Indicator accounting for the ordinal nature of item response data2019Ingår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 14, nr 3, s. -3, artikel-id e0213533Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background Insomnia symptoms are common among young adults and affect about 5% to 26% of 19 to 34-year-olds. In addition, insomnia is associated with poor mental health and may affect daily performance. In research, as well as in clinical practice, sleep questionnaires are used to screen for and diagnose insomnia. However, most questionnaires are not developed according to current DSM-5 diagnostic criteria. An exception is the recently developed Sleep Condition Indicator (SCI), an eight-item scale screening for insomnia. Aim The aim of this study was to perform a Classical Test Theory (CTT) based psychometric evaluation of the SCI in a sample of Swedish university students, by taking the ordinal nature of item level data into account. Methods The SCI was translated into Swedish and distributed online to undergraduate students at three Swedish universities, within programs of health, psychology, science or economy. Of 3673 invited students, 634 (mean age 26.9 years; SD = 7.4) completed the questionnaire that, in addition to the SCI, comprised other scales on sleep, stress, lifestyle and students' study environment. Data were analyzed according to CTT investigating data completeness, item homogeneity and unidimensionality. Results Polychoric based explorative factor analysis suggested unidimensionality of the SCI, and internal consistency was good (Cronbach's alpha, 0.91; ordinal alpha, 0.94). SCI scores correlated with the Insomnia Severity Index (-0.88) as well as with sleep quality (-0.85) and perceived stress (-0.50), supporting external construct validity. Conclusions These observations support the integrity of the of the SCI. The SCI demonstrates sound CTT-based psychometric properties, supporting its use as an insomnia screening tool.

    A comparative study of the environmental impact from transportation of prefabricated building elements using wood or concrete2019Ingår i: International Journal of Engineering and Technology, ISSN 1793-8236, E-ISSN 1793-8244, Vol. 11, nr 3, s. 154-161Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    As many as 240 of Sweden's 290 municipalities estimated that there existed a housing shortage within their region. Therefore, many homes are required to be built in a relatively short period to fulfil the demand.  Production is required to take into consideration sustainable building solutions to reduce climate impact. Hence, logistics must become more efficient to contribute to an environmental solution, and the use of transports should be examined reducing the effect of heavy vehicles to meet the climate objectives.

    The focus of this study is to identify differences between the transportation of materials for building projects based on wood or concrete. Different key performance indicators were derived from the collected data and presented in this study, which resulted in two formulas focusing on transport- and environmental impact. 

    The KPI’s indicates that the weight of the load does not have an important impact on the amount of emitted CO2, but it is the number of transports associated with the projects that are the main problem regarding emissions and environmental impact. Hence, the number of transports and the amount of CO2 emissions can be calculated by the support of the formulas derived from this study.

    A Comparison Between Four Dynamic Energy Modeling Tools for Simulation of Space Heating Demand of Buildings.2019Ingår i: Cold Climate HVAC 2018. CCC 2018 / [ed] Johansson D., Bagge H., Wahlström Å., Springer, 2019, s. 701-711Konferensbidrag (Refereegranskat)
    Abstract [en]

    Different building energy modelling programs exist and are widely used to calculate energy balance of building in the context of energy renovation of existing buildings or in the design of energy performance of new buildings. The different tools have unique benefits and drawbacks for different conditions. In this study, four different types of building energy system modelling tools including TRNSYS, Energy Plus, IDA-Indoor Climate Energy (IDA-ICE) and VIP-Energy are used to calculate the energy balance of a recently built six-storey apartment building in Växjö, Sweden. The building is designed based on the current Swedish building code. The main outcomes of the software include hourly heating and cooling demands and indoor temperature profiles. We explore the general capabilities of the software and compare the results between them. For the studied building with similar input conditions such as weather climate data file, infiltration and ventilation ratio and internal heat gain, IDA-ICE modeled the highest space heating demand while the TRNSYS the lowest due to the simplification of thermal bridges. The main advance feature of VIP-Energy is the detail thermal bridge analysis while the main drawback is the complexity of using the model. EnergyPlus and TRNSYS can be used for energy supply system integration with the ability to add mathematical sub-modules to the models.

    A Comprehensive Model for the Quantitative Estimation of Seed Dispersal by Migratory Mallards2019Ingår i: Frontiers in Ecology and Evolution, E-ISSN 2296-701X, Vol. 7, s. 1-14, artikel-id 40Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Long-distance seed dispersal is an important ecosystem service provided by migratory animals. Plants inhabiting discrete habitats, like lakes and wetlands, experience dispersal limitation, and rely heavily on zoochory for their spatial population dynamics. Granivorous waterbirds may disperse viable seeds of wetland plants over long distances during migration. The limited knowledge of waterbird migration has long hampered the evaluation of the importance of waterbirds in seed dispersal, requiring key metrics such as realistic dispersal distances. Using recent GPS tracking of mallards during spring migration, we built a mechanistic seed dispersal model to estimate realistic dispersal distances. Mallards are abundant, partially migratory ducks known to consume seeds of >300 European plant species. Based on the tracking data, we informed a mallard migration simulator to obtain a probabilistic spring migration model for the mallard population wintering at Lake Constance in Southern Germany. We combined the spring migration model with seed retention curves to develop seed dispersal kernels. We also assessed the effects of pre-migratory fasting and the availability of suitable deposition habitats for aquatic and wetland plants. Our results show that mallards at Lake Constance can disperse seeds in the northeastern direction over median distances of 293 and 413 km for seeds with short and long retention times, respectively, assuming a departure immediately after foraging. Pre-migratory fasting strongly affected the dispersal potential, with only 1-7% of ingested seeds left for dispersal after fasting for 12 h. Availability of a suitable deposition habitat was generally <5% along the migratory flyway. The high probability of seed deposition in a freshwater habitat during the first stopover, after the mallards completed the first migratory flight, makes successful dispersal most likely to happen at 204-322 km from Lake Constance. We concluded that the directed long-distance dispersal of plant seeds, realized by mallards on spring migration, may contribute significantly to large scale spatial plant population dynamics, including range expansion in response to shifting temperature and rainfall patterns under global warming. Our dispersal model is the first to incorporate detailed behavior of migratory waterbirds and can be readily adjusted to include other vector species when tracking data are available.

    A continuum micromechanics approach to the elasticity and strength of planar fiber networks: Theory and application to paper sheets2019Ingår i: European journal of mechanics. A, Solids, ISSN 0997-7538, E-ISSN 1873-7285, Vol. 75, s. 516-531Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    2D materials such as planar fibrous networks exhibit several mechanical peculiarities, which we here decipher through a 3D-to-2D transition in the framework of continuum micromechanics or random mean-field homogenization theory. Network-to-fiber concentration (or “downscaling”) tensors are derived from Eshelby-Laws matrix-inclusion problems, specified for infinitely long, infinitely flat fibers, and for infinitely flat spheroidal pores of vanishing stiffness. Overall material failure is associated with microscopic shear failure orthogonal to the fiber direction. Corresponding structure-property relations between porosity on the one hand, and in-plane stiffness as well as strength on the other hand, appear as linear. This is in good agreement with mechanical experiments carried out on pulp fibers, on pulp fiber-to-pulp fiber bonds, and on corresponding paper sheets.

    A cross-country comparison of accommodation manager perspectives on online review manipulation2019Ingår i: Current Issues in Tourism, ISSN 1368-3500, E-ISSN 1747-7603, Vol. 22, nr 14, s. 1744-1763Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Accommodation businesses are increasingly dependent on a limited number of reservation platforms. A significant feature of these platforms is guest evaluations, which are transformed into ratings and rankings. As the positioning of the business in comparison to competitors determines customer demand, accommodation managers have considerable interest in maintaining or improving their online reputation. One response may be to engage in manipulation strategies. This paper presents the results of a survey including 270 hotel managers in five countries, Germany, Israel, Norway, Sweden and Switzerland. Managers confirm growing competition as a result of ratings and rankings, and they report that guests are increasingly aware of the importance of reviews. To avert negative online feedback impacts, managers intervene strategically. The paper discusses new market pressures, emergent consumer judgement culture and consumer citizenship, opportunities for legal redress and the emerging importance of reputation management strategies.

    A hedonic motivation model in virtual reality tourism: Comparing visitors and non-visitors2019Ingår i: International Journal of Information Management, ISSN 0268-4012, E-ISSN 1873-4707, Vol. 46, s. 236-249Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Virtual reality (VR) tourism provides consumers with the opportunity to experience a destination in VR and can play a significant role in encouraging visitation and engaging in particular travel activities and behaviors. Hedonic motivation adoption frameworks with flow state and subjective well-being have been shown to have significant roles in continued use of information technology. However, research on a theoretically integrated hedonic motivation system adoption model (HMSAM) specifically with enjoyment, flow state, subjective wellbeing, and continued use has not previously been conducted with respect to VR tourism. To address this gap, this study develops and investigates a conceptually comprehensive model on the effect of consumers' hedonic behaviors on continued use, with the moderating role of visitor or non-visitor at the destination portrayed in VR tourism. Results identified the highly significant effect of consumers' perceived enjoyment on flow state and of flow state on subjective well-being. Continued use was greatly influenced by flow state and subjective wellbeing. Importantly for destinations association between usefulness and flow state had a significant moderating effect depending on whether a visitor or non-visitor. The findings offer new knowledge to researchers and industry in the VR tourism fields.

    A human whole-blood model to study the activation of innate immunity system triggered by nanoparticles as a demonstrator for toxicity2019Ingår i: Science and Technology of Advanced Materials, ISSN 1468-6996, E-ISSN 1878-5514, Vol. 20, nr 1, s. 688-698Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    In this review article, we focus on activation of the soluble components of the innate immune system triggered by nonbiological compounds and stress variances in activation due to the difference in size between nanoparticles (NPs) and larger particles or bulk material of the same chemical and physical composition. We then discuss the impact of the so-called protein corona which is formed on the surface of NPs when they come in contact with blood or other body fluids. For example, NPs which bind inert proteins, proteins which are prone to activate the contact system (e.g., factor XII), which may lead to clotting and fibrin formation or the complement system (e.g., IgG or C3), which may result in inflammation and vascular damage. Furthermore, we describe a whole blood model which we have developed to monitor activation and interaction between different components of innate immunity: blood protein cascade systems, platelets, leukocytes, cytokine generation, which are induced by NPs. Finally, we describe our own studies on innate immunity system activation induced by three fundamentally different species of NPs (two types of engineered NPs and diesel NPs) as demonstrator of the utility of an initial determination of the composition of the protein corona formed on NPs exposed to ethylenediaminetetraacetic acid (EDTA) plasma and subsequent analysis in our whole blood model.

    A modified combined C-BARQ and QoL for both the companion dog and its owner. An embryo to a companion dog welfare measurement?2019Ingår i: Applied Animal Behaviour Science, ISSN 0168-1591, E-ISSN 1872-9045, Vol. 213, s. 91-106Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The results of this pilot study demonstrate that it is possible to construct a reliable questionnaire from prior validated surveys. This questionnaire displays possible suitability for further development into a tool for a comprehensive dog welfare assessment. The welfare model used is assuming that canine welfare consists of three major considerations, the dogs’ behavior, the dogs’ quality of life (QoL dog) and the owner’s quality of life as pertaining to being a dog owner (QoL Owner). A questionnaire was constructed and tested. Three different parts from reliable and validated sections of previous surveys were included: 1) a modified C-BARQ, 2) QoL for the dog, and 3) QoL owner. 185 satisfactory answers were obtained from the respondents, dog owners in Sweden, Canada and USA. Principal component factor analysis rendered 13 extracted factors similar to the original questionnaires, suggesting that the construct is valid. Eleven of the thirteen factors showed moderate internal consistency of Cronbach’s alpha >0.7, the remaining two factors were relatively low with Cronbach’s alpha >0.6.

    Several significant correlations between the extracted factors were found. Quality of life as a dog owner (QoL owner) was significantly affected by stress caused by dogs displaying fear, excitability and separation anxiety. No significant correlations were found between any factors describing aggressive behaviors and the dogs QoL or QoL owner. Several significant correlations were found between the extracted factors and the demographics, for instance, the Swedes are more active with their dogs compared to Americans and Canadians. Further investigations should be commenced to validate the results in a larger population.

    A National Study of Patient Safety Culture in Hospitals in Sweden2019Ingår i: Journal of patient safety, ISSN 1549-8417, E-ISSN 1549-8425Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE: Using the Hospital Survey on Patient Culture, our aim was to investigate the patient safety culture in all Swedish hospitals and to compare the culture among managers, physicians, registered nurses, and enrolled nurses and to identify factors associated with high overall patient safety.

    METHODS: The study used a correlational design based on cross-sectional surveys from health care practitioners in Swedish health care (N = 23,781). We analyzed the associations between overall patient safety (outcome variable) and 12 culture dimensions and 5 background characteristics (explanatory variables). Simple logistic regression analyses were conducted to determine the bivariate association between each explanatory variable and the outcome variable. The explanatory variables were entered to determine the multivariate associations between the variables and the outcome variable.

    RESULTS: The highest rated culture dimensions were "teamwork within units" and "nonpunitive response to error," and the lowest rated dimensions were "management support for patient safety" and "staffing." The multivariate analysis showed that long professional experience (>15 years) was associated with increased probability for high overall patient safety. Compared with general wards, the probability for high overall patient safety was higher for emergency care but lower for psychiatric care. The probability for high overall patient safety was higher for both enrolled nurses and physicians compared with managers.

    CONCLUSIONS: The safety culture dimensions of the Hospital Survey on Patient Culture contributed far more to overall patient safety than the background characteristics, suggesting that these dimensions are very important in efforts to improve the overall patient safety culture.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

    A numerical study of the effect of green-state moisture content on stress development in timber boards during drying2019Ingår i: Wood and Fiber Science, ISSN 0735-6161, Vol. 51, nr 1, s. 41-57Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Timber boards manufactured with a traditional sawing pattern often contain both heartwood andsapwood. In such boards, internal constraints can occur during drying because of a radial variation in greenstate(GS) MC between the heartwood (30-60%) and sapwood region (120-200%). Despite such knowledge,the initial MC is seldom considered when evaluating kiln-drying schedules. The effect of GS MC on thedevelopment of tangential tensile stress during drying is studied for four types of timber boards. A numericalmodel was developed that can simulate transient nonlinear orthotropic moisture flow and moisture–inducedstress and distortion in wood with the use of the finite element method. The stress analysis considers elastic,hygroscopic, and mechano-sorptive strain. The study shows that the GS MC does not significantly influencethe maximum stress state, but that it does influence the time at which the maximum tangential tensile stressoccurs at different exchange surfaces. This results in several periods in the drying schedule where unfavorablehigh stress situations in the tangential direction arise, which could lead to crack propagation.

    A Randomized Controlled Study of Group-Administered Cognitive Behavioral Therapy for Hypersexual Disorder in Men2019Ingår i: Journal of Sexual Medicine, ISSN 1743-6095, E-ISSN 1743-6109, Vol. 16, nr 5, s. 733-745Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Hypersexual disorder (HD) is defined as a condition in which the individual loses control over engagement in sexual behaviors, leading to distress and negative effects on key life areas. Cognitive behavioral therapy (CBT) has been proven to reduce symptoms of hypersexual behavior; however, no randomized controlled study of CBT interventions for HD has been reported previously. Aim: To investigate the efficacy of group-administered CBT for HD. Methods: Male participants (n = 137) diagnosed with HD, were randomized between 7 weeks of group-administered CBT (n = 70) and a waitlist control receiving the intervention after 8 weeks (n = 67). Measurements were administered at pre-, mid-, and posttreatment, with follow-up after 3 and 6 months. Outcomes: The primary outcome was the Hypersexual Disorder: Current Assessment Scale (HD: CAS), and secondary outcomes were the Sexual Compulsivity Scale (SCS) and measures of depression (Montgomery-Asberg Depression Rating Scale (MADRS-S), psychological distress (Clinical Outcomes in Routine Evaluation Outcome Measure (CORE-OM), and treatment satisfaction (CSQ-8). Results: A significantly greater decrease in HD symptoms and sexual compulsivity, as well as significantly greater improvements in psychiatric well-being, were found for the treatment condition compared with the waitlist. These effects remained stable at 3 and 6 months after treatment. Clinical Implications: CBT can ameliorate HD symptoms and psychiatric distress, suggesting that the CBT program may serve as a first-line treatment in clinical settings. Strengths & Limitations: This is the first randomized controlled study evaluating the efficacy of a CBT programin a rather large sample of HD-specific diagnosed men. The long-termtreatment effects are vague due to the low response rate on follow-up measurements, and the efficacy of this program for hypersexual women remains unknown. Conclusion: This study supports the efficacy of a group-administered CBT program as a treatment option for HD; however, future studies should include women, comprise dismantling analysis of the constituting interventions, and evaluate other treatment formats, for example, administration via the Internet.

    A review of Växjö Municipality’s operational and strategic development constraints related to the construction of wooden multi-family houses2019Ingår i: Journal of Civil Engineering and Architecture, ISSN 1934-7359, E-ISSN 1934-7367Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Sweden has a housing shortage, which the Swedish authorities expect to continue until 2025. Producers of wooden multi-family houses have a relatively small market share in comparison to traditional building materials. The limited capability to fulfil the increased building demand also restricts the possibilities for development towards innovation, bio-economy and sustainability. The municipalities in Sweden have responsible for planning of the building development in their region based on their projected requirements and strategies. Combining this with a desire to develop sustainable building solutions based on wood increases the complexity. Currently, public building developments are achieved through the public procurement act or the land allocation activity, dependent on their development strategy. This normally involves the development of local strategies regarding, e.g. design, material choice and geographical development. By identifying market drivers enables improved market entry activities related to public building initiatives using wood-based solutions. Hence, by improving transparency in the land allocation activity generate enhanced possibilities for the companies to respond successfully to the requests submitted by the municipalities. This knowledge is used to better understand the required strategic development for the companies, the government and the municipalities to increase the use of sustainable building materials in Swedish multi-family housing projects.

    A Robust, Non-Cooperative Localization Algorithm in the Presence of Outlier Measurements in Ocean Sensor Networks2019Ingår i: Sensors, ISSN 1424-8220, E-ISSN 1424-8220, Vol. 19, nr 12, s. 1-18, artikel-id 2708Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    As an important means of multidimensional observation on the sea, ocean sensor networks (OSNs) could meet the needs of comprehensive information observations in large-scale and multifactor marine environments. In what concerns OSNs, accurate location information is the basis of the data sets. However, because of the multipath effect-signal shadowing by waves and unintentional or malicious attacks-outlier measurements occur frequently and inevitably, which directly degrades the localization accuracy. Therefore, increasing localization accuracy in the presence of outlier measurements is a critical issue that needs to be urgently tackled in OSNs. In this case, this paper proposed a robust, non-cooperative localization algorithm (RNLA) using received signal strength indication (RSSI) in the presence of outlier measurements in OSNs. We firstly formulated the localization problem using a log-normal shadowing model integrated with a first order Taylor series. Nevertheless, the problem was infeasible to solve, especially in the presence of outlier measurements. Hence, we then converted the localization problem into the optimization problem using squared range and weighted least square (WLS), albeit in a nonconvex form. For the sake of an accurate solution, the problem was then transformed into a generalized trust region subproblem (GTRS) combined with robust functions. Although GTRS was still a nonconvex framework, the solution could be acquired by a bisection approach. To ensure global convergence, a block prox-linear (BPL) method was incorporated with the bisection approach. In addition, we conducted the Cramer-Rao low bound (CRLB) to evaluate RNLA. Simulations were carried out over variable parameters. Numerical results showed that RNLA outperformed the other algorithms under outlier measurements, notwithstanding that the time for RNLA computation was a little bit more than others in some conditions.

    A systematic literature review on the detection of smells and their evolution in object-oriented and service-oriented systems2019Ingår i: Software, practice & experience, ISSN 0038-0644, E-ISSN 1097-024X, Vol. 49, nr 1, s. 3-39Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    This systematic literature review paper investigates the key techniques employed to identify smells in different paradigms of software engineering from object-oriented (OO) to service-oriented (SO). In this review, we want to identify commonalities and differences in the identification of smells in OO and SO systems. Our research method relies on an automatic search from the relevant digital libraries to find the studies published since January 2000 on smells until December 2017. We have conducted a pilot and author-based search that allows us to select the 78 most relevant studies after applying inclusion and exclusion criteria. We evaluated the studies based on the smell detection techniques and the evolution of different methodologies in OO and SO. Among the 78 relevant studies selected, we have identified six different studies in which linguistic source code analysis received less attention from the researchers as compared to the static source code analysis. Smells like the yo-yo problem, unnamed coupling, intensive coupling, and interface bloat received considerably less attention in the literature. We also identified a catalog of 30 smells infrequently reported for SO systems and that require further attention. Moreover, a suite of 20 smells reported for SO systems can also be detected using static source code metrics in OO. Finally, our review highlighted three major research trends that are further subdivided into 20 research patterns initiating the detection of smells toward their correction.

    A Task Scheduling Model for Multi-CPU and Multi-Hard Disk Drive in Soft Real-time Systems2019Ingår i: International Journal of Information Technology and Computer Science, ISSN 2074-9007, E-ISSN 2074-9015, Vol. 11, nr 1Artikel i tidskrift (Övrigt vetenskapligt)
    Abstract [en]

    In recent years, by increasing CPU and I/O devices demands, running multiple tasks simultaneously becomes a crucial issue. This paper presents a new task scheduling algorithm for multi-CPU and multi-Hard Disk Drive (HDD) in soft Real-Time (RT) systems, which reduces the number of missed tasks. The aim of this paper is to execute more parallel tasks by considering an efficient trade-off between energy consumption and total execution time. For study purposes, we analyzed the proposed scheduling algorithm, named HCS (Hard disk drive and CPU Scheduling) in terms of the task set utilization, the total execution time, the average waiting time and the number of missed tasks from their deadlines. The results show that HCS algorithm improves the above mentioned criteria compared to the HCS_UE (Hard disk drive and CPU Scheduling _Unchanged Execution time) algorithm.

    A two-step procedure to identify stance constructions in discourse from political blogs2019Ingår i: Corpora, ISSN 1749-5032, E-ISSN 1755-1676, Vol. 14, nr 3Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Brexit Blog Corpus (BBC) is a collection of texts extracted from political blogs, which, in a recent study, was annotated according to a cognitive-functional stance framework by two independent annotators (Annotator A and B) using semantic criteria (Simaki et al. 2017). The goal was to label the stance or stances taken based on the overall meaning of a set of utterances. The annotators were not instructed to identify the lexical forms that were used to express the stances. In this study, we make use of those stance labelled utterances as a springboard to approach stance-taking in text from the opposite point of view, namely from how stance is realised through language. Our aim is to provide a description of the specific lexical elements used to express six stance categories, i.e., CONTRARIETY, HYPOTHETICALITY,  NECESSITY, PREDICTION, SOURCE OF KNOWLEDGE, and UNCERTAINTY. To this end, we followed a two-step experimental procedure. First, we performed a quantitative analysis of the stance labelled utterances in order to identify the lexical realisations of each stance category. Second, we carried out a meta-annotation of the data. Annotator B was instructed to single out the actual lexical forms of the constructions that triggered his semantic stance category decisions. This meta-annotation procedure made it possible for us to sift out the most salient lexical realisations of the constructions of each of the six category types on the basis of the qualitative assessments made by Annotator B. We then compared the results of the quantitative and the qualitative approaches, and we present a list of shared stance expressions for each stance category type.

    A typology of market-seeking investments: Swedish firms in China2019Ingår i: International Journal of Emerging Markets, ISSN 1746-8809, E-ISSN 1746-8817, Vol. 14, nr 1, s. 254-262Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose Regarding globalization trends, it is essential for multinational corporations (MNCs) to operate in China if they are to succeed in the international business environment. It is therefore vital to study how those MNCs investing in China have fared. The purpose of this paper is to devise a robust conceptual framework for the evolvement of market-seeking investments in emerging markets. Design/methodology/approach The typology is based on a network approach to internationalization processes, where a case study is made of Swedish MNCs' experience of the Chinese market. Findings The case study contributes to the mostly static foreign direct investment (FDI) theory as well as the entry mode approach, both of which have paid little attention to the FDI carried out by MNCs in emerging markets 5-15 years after initial entry. Originality/value The case study also contributes to the mostly static FDI theory as well as the entry mode approach, both of which have paid little attention to the various types of FDI carried out by MNCs in emerging markets 5-15 years after initial entry.

    A versatile catalyst-free perfluoroaryl azide-aldehyde-amine conjugation reaction2019Ingår i: Materials Chemistry Frontiers, E-ISSN 2052-1537, Vol. 3, nr 2, s. 251-256Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In a tri-component reaction, an electrophilically-activated perfluoroaryl azide, an enolizable aldehyde and an amine react readily at room temperature without any catalysts in solvents including aqueous conditions to yield a stable amidine conjugate. The versatility of this reaction is demonstrated in the conjugation of an amino acid without prior protection of the carboxyl group, and in the synthesis of antibiotic-nanoparticle conjugates.

    Academic Vocabulary in Wikipedia Articles: Frequency and Dispersion in Uneven Datasets2019Ingår i: From Data to Evidence in English Language Research / [ed] Carl Suhr, Terttu Nevalainen, Irma Taavitsainen, Leiden: Brill Academic Publishers, 2019, s. 282-306Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    Despite its popularity, the status of Wikipedia in higher education settings remains somewhat controversial, and the linguistic characteristics of the genre have not been exhaustively described. This exploratory paper takes a data-driven approach to assessing the use of academic vocabulary in Wikipedia articles. Our analysis is based on Coxhead’s Academic Word List, and the data comes from the Westbury Lab Wikipedia Corpus. We employ methods of statistical data analysis to classify Wikipedia articles according to the frequencies of academic words, and apply the same procedure to a comparable set of texts representing another genre, published research articles. The unsupervised classification procedure groups the articles according to academic content regardless of topic, which allows us to measure genre-specific similarities. The findings of the study show that academic words are common in both genres in focus, and more interestingly, if we look at aggregate frequencies of academic words, Wikipedia articles are not markedly different from RAs within the same discipline. This being said, we can observe disciplinary differences in the distribution of academic words in Wikipedia, such that Economics writing contains more academic words than the other two disciplines in focus. Disciplinary differences can likewise be observed in the distribution of individual academic words.

    Acclimation and adaptation components of the temperature dependence of plant photosynthesis at the global scale2019Ingår i: New Phytologist, ISSN 0028-646X, E-ISSN 1469-8137, Vol. 222, nr 2, s. 768-784Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The temperature response of photosynthesis is one of the key factors determining predicted responses to warming in global vegetation models (GVMs). The response may vary geographically, owing to genetic adaptation to climate, and temporally, as a result of acclimation to changes in ambient temperature. Our goal was to develop a robust quantitative global model representing acclimation and adaptation of photosynthetic temperature responses.

    We quantified and modelled key mechanisms responsible for photosynthetic temperature acclimation and adaptation using a global dataset of photosynthetic CO2 response curves, including data from 141 C3 species from tropical rainforest to Arctic tundra. We separated temperature acclimation and adaptation processes by considering seasonal and common-garden datasets, respectively.

    The observed global variation in the temperature optimum of photosynthesis was primarily explained by biochemical limitations to photosynthesis, rather than stomatal conductance or respiration. We found acclimation to growth temperature to be a stronger driver of this variation than adaptation to temperature at climate of origin.

    We developed a summary model to represent photosynthetic temperature responses and showed that it predicted the observed global variation in optimal temperatures with high accuracy. This novel algorithm should enable improved prediction of the function of global ecosystems in a warming climate.

    Achieving a trade‐off construction solution using BIM, an optimization algorithm, and a multi‐criteria decision‐making method2019Ingår i: Buildings, ISSN 2075-5309, E-ISSN 2075-5309, Vol. 9, nr 4, s. 1-14, artikel-id 81Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Energy Performance of Building Directive obligated all European countries to reduce the energy requirements of buildings while simultaneously improving indoor environment quality. Any such improvements not only enhance the health of the occupants and their productivity, but also provide further economic benefits at the national level. Accomplishing this task requires a method that allows building professionals to resolve conflicts between visual and thermal comfort, energy demands, and life‐cycle costs. To overcome these conflicts, this study exploits the incorporation of building information modelling (BIM), the design of experiments as an optimization algorithm, and the analytical hierarchy process (AHP) into a multi‐criteria decision‐ making method. Any such incorporation can (i) create constructive communication between building professionals, such as architects, engineers, and energy experts; (ii) allow the analysis of the performance of multiple construction solutions with respect to visual and thermal comfort, energy demand, and life‐cycle costs; and (iii) help to select a trade‐off solution, thereby making a suitable decision. Three types of energy‐efficient windows, and five types of ground floors, roofs, and external wall constructions were considered as optimization variables. The incorporation of several methods allowed the analysis of the performance of 375 construction solutions based on a combination of optimization variables, and helped to select a trade‐off solution. The results showed the strength of incorporation for analyzing big‐data through the intelligent use of BIM and a simulation in the field of the built environment, energy, and costs. However, when applying AHP, the results are strongly contingent on pairwise comparisons

    Activation and Inactivation of the FLT3 Kinase: Pathway Intermediates and the Free Energy of Transition2019Ingår i: Journal of Physical Chemistry B, ISSN 1520-6106, E-ISSN 1520-5207, Vol. 123, nr 26, s. 5385-5394Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aberrant expression of kinases is often associated with pathologies such as cancer and autoimmune diseases. Like other types of enzymes, kinases can adopt active and inactive states, where a shift toward more stable active state often leads to disease. Dozens of kinase inhibitors are, therefore, used as drugs. Most of these bind to either the inactive or active state. In this work, we study the transitions between these two states in FLT3, an important drug target in leukemias. Kinases are composed of two lobes (N- and C-terminal lobes) with the catalytic site in-between. Through projection of the largest motions obtained through molecular dynamics (MD) simulations, we show that each of the end-states (active or inactive) already possess the ability for transition as the two lobes rotate which initiates the transition. A targeted simulation approach known as essential dynamics sampling (EDS) was used to speed up the transition between the two protein states. Coupling the EDS to implicit-solvent MD was performed to estimate the free energy barriers of the transitions. The activation energies were found in good agreement with previous estimates obtained for other kinases. Finally, we identified FLT3 intermediates that assumed configurations that resemble that of the c-Src nonreceptor tyrosine kinase. The intermediates show better binding to the drug ponatinib than c-Src and the inactive state of FLT3. This suggests that targeting intermediate states can be used to explain the drug-binding patterns of kinases and for rational drug design.

    Adaptation and psychometric properties of the Norwegian version of the heart continuity of care questionnaire (HCCQ)2019Ingår i: BMC Medical Research Methodology, ISSN 1471-2288, E-ISSN 1471-2288, Vol. 19, s. 1-15, artikel-id 62Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Continuity of cardiac care after hospital discharge is a priority, especially as healthcare systems become increasingly complex and fragmented. There are few available instruments to measure continuity of cardiac care, especially from the patient perspective. The aim of this study was (1) to translate and adapt the Heart Continuity of Care Questionnaire (HCCQ) to conditions in Norway, and (2) to determine its psychometric properties in self-report format administered to patients after percutaneous coronary intervention (PCI). Methods: The HCCQ was first translated into Norwegian from the original English version, following a widely used cross-cultural adaptation process. Data were collected before hospital discharge and in a follow-up after 2months. To assess psychometric properties, a confirmatory factor analysis (CFA) was performed and three aspects of construct validity were evaluated: structural validity, hypotheses testing and cross-cultural validation. Internal consistency of the HCCQ subscales was calculated using Cronbach's alpha, while intra-class correlation (ICC) was used to assess test-retest reliability. Additionally, socio-demographic and patient-reported data were collected to correlate with HCCQ scores. Results: Of those included at baseline, 436 (76%) completed the questionnaires after 2months. CFA suggested that the fit of the HCCQ data to a 3-factor model was modest (RMSEA = 0.11, CFI = 0.90, TLI = 0.90). However, convergent validity was satisfactory, based on existing research. Internal consistency was good, as indicated by its Cronbach's alphas: total continuity of care (0.95); informational (0.93), relational (0.87), and management (0.89) continuity. The ICC for the total HCCQ score was 0.80 (95% CI [0.71, 0.87] p<0.001). As indicated by negative care experiences (rated as 1 or 2 on the five-point scale), patients seemed to have limited knowledge about medical treatment, lifestyle modification and follow-up after PCI. Participation in cardiac rehabilitation and longer consultations with the general practitioner after hospital discharge were positively correlated with better continuity of care. Conclusions: Implementation of the HCCQ will likely support healthcare providers and researchers in identifying problem areas of continuity of cardiac care and in evaluating interventions aimed at improving continuity of care.

    Adaptations of early development to local spawning temperature in anadromous populations of pike (Esox lucius)2019Ingår i: BMC Evolutionary Biology, ISSN 1471-2148, E-ISSN 1471-2148, Vol. 19, s. 1-13, artikel-id 148Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: In the wake of climate change many environments will be exposed to increased and more variable temperatures. Knowledge about how species and populations respond to altered temperature regimes is therefore important to improve projections of how ecosystems will be affected by global warming, and to aid management. We conducted a common garden, split-brood temperature gradient (4.5 degrees C, 9.7 degrees C and 12.3 degrees C) experiment to study the effects of temperature in two populations (10 families from each population) of anadromous pike (Esox lucius) that normally experience different temperatures during spawning. Four offspring performance measures (hatching success, day degrees until hatching, fry survival, and fry body length) were compared between populations and among families. Results: Temperature affected all performance measures in a population-specific manner. Low temperature had a positive effect on the Harfjarden population and a negative effect on the Lervik population. Further, the effects of temperature differed among families within populations. Conclusions: The population-specific responses to temperature indicate genetic differentiation in developmental plasticity between populations, and may reflect an adaptation to low temperature during early fry development in Harfjarden, where the stream leading up to the wetland dries out relatively early in the spring, forcing individuals to spawn early. The family-specific responses to temperature treatment indicate presence of genetic variation for developmental plasticity (G x E) within both populations. Protecting between- and within-population genetic variation for developmental plasticity and high temperature-related adaptive potential of early life history traits will be key to long-term viability and persistence in the face of continued climate change.

    Adherence to risk management guidelines for drugs which cause vitamin D deficiency – big data from the Swedish health system2019Ingår i: Drug, Healthcare and Patient Safety, ISSN 1179-1365, E-ISSN 1179-1365, Vol. 11, s. 19-28Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: Several medications are known to cause vitamin D deficiency. The aim of this study is to describe vitamin D testing and supplementation in patients using these “risk medications”, thereby assessing adherence to medical guidelines.Patients and methods: A database with electronic health records for the population in a Swedish County (≈240,000 inhabitants) was screened for patients prescribed the pre-defined “risk medications” during a 2-year period (2014–2015). In total, 12,194 patients were prescribed “risk medications” pertaining to one of the three included pharmaceutical groups. Vitamin D testing and concomitant vitamin D supplementation, including differences between the included pharmaceutical groups, was explored by matching personal identification numbers.Results: Corticosteroids were prescribed to 10,003 of the patients, antiepileptic drugs to 1,101, and drugs mainly reducing vitamin D uptake to 864. Two hundred twenty-six patients were prescribed >1 “risk medication”. Seven hundred eighty-seven patients (6.5%) had been tested during the 2-year period. There were no differences regarding testing frequency between groups. Concomitant supplements were prescribed to 3,911 patients (32.1%). It was more common to be prescribed supplements when treated with corticosteroids. Vitamin D supplementation was more common among tested patients in all three groups. Women were tested and supplemented to a higher extent. The mean vitamin D level was 69 nmol/L. Vitamin D deficiency was found in 24.1% of tested patients, while 41.3% had optimal levels. It was less common to be deficient and more common to have optimal levels among patients prescribed corticosteroids.Conclusion: Adherence to medical guidelines comprising testing and supplementation of patients prescribed drugs causing vitamin D deficiency needs improvement in Sweden.

    Age Discrimination in Hiring Decisions: Evidence from a Field Experiment in the Labor Market2019Ingår i: Labour Economics, ISSN 0927-5371, E-ISSN 1879-1034Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper shows the results of a field experiment in which over 6,000 fictitious resumes with randomly assigned information about age (35-70 years) were sent to Swedish employers with vacancies in low- and medium-skilled occupations. We find that the callback rate begins to fall substantially for workers in their early 40s and becomes very low for workers close to the retirement age. The decline in callback rate by age is steeper for women than for men. Employer stereotypes about the ability to learn new tasks, flexibility, and ambition seem to be an important explanation for age discrimination.

    Amatörorkestrar som lärandemiljö för musikhögskolestudenter: En studie om Musikhögskolan i Malmö och fyra amatörorkestrar2019Bok (Övrigt vetenskapligt)
    Abstract [sv]

    Orkesterspel ingår som en vanlig ensembleform inom musikhögskolors utbildningar, och vissa utbildningar är till och med specifikt inriktade på symfoniorkesterspel. Dock visar det sig att studenter ibland spelar i amatörorkestrar samtidigt som de studerar på musikhögskola. Lärare på musikhögskolor rekommenderar ibland studenter att delta i amatörverksamhet eftersom de anser att studenterna inte får tillräckligt med erfarenhet av, eller kunskaper om, orkesterspel inom utbildningen. Detta gör att det skapas en parallell utbildning för musikhögskolestudenterna vid sidan av den formella utbildningen. Denna studie fokuserar på vad musikhögskolestudenter lär sig genom att delta i amatörorkesterverksamhet och vad det tillför det utbildningen.

    Studien är en fallstudie över en läromiljö: Musikhögskolan i Malmö och fyra amatörsymfoniorkestrar där musikhögskolestudenter ingår. I studien har åtta intervjuer utförts, fyra med amatörorkesterdirigenter och fyra med ledning för musikhögskolan.

    Studien visar att deltagandet och lärandet i amatörorkestrarna beror på delar som musikhögskolestudenterna saknar i sin utbildning, samt personliga kontakter mellan dirigenter, lärare och studenter. Amatörorkesterverksamheten kan i hög grad betraktas som ett komplement till musikhögskolans verksamhet, även om det finns aspekter som inte kan tillgodoses i lika hög grad inom musikhögskolorna som kunskaper om pedagogiska roller, formandet av en professionell yrkesroll och kunskap om olika sociala kontexter. Relationen mellan musikhögskolan och amatörorkestrarna kännetecknas av informella kontakter och informella samarbeten av tradition, där autonomi är en viktig aspekt. En annan aspekt är öppenheten inför en föränderlig arbetsmarknad och kulturscen där nya former av samarbeten är möjliga och önskvärda.

    Ambulance nurses’ experiences of patient relationships in urgent and emergency situations: a qualitative exploration2019Ingår i: Clinical Ethics, ISSN 1477-7509, E-ISSN 1758-101X, Vol. 14, nr 2, s. 70-79Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background

    The ambulance service provides emergency care to meet the patient’s medical and nursing needs. Based on professional nursing values, this should be done within a caring relationship with a holistic approach as the opposite would risk suffering related to disengagement from the patient’s emotional and existential needs. However, knowledge is sparse on how ambulance personnel can meet caring needs and avoid suffering, particularly in conjunction with urgent and emergency situations.

    Aim

    The aim of the study was to explore ambulance nurses’ experiences of relationships with patients in urgent and emergency situations.

    Methods

    Data collection was performed using individual open-ended interviews with six ambulance nurses. The data were analyzed using a thematic analysis.

    Results

    Relationships with patients during urgent and emergency assignments emerged as three themes: “Ambiguous silence,” “Professional competence” and “Challenging inadequacy” comprising eight sub-themes in total. The result shows that the ambulance nurses found it difficult to prioritize between medical care and establishing a caring relationship with the patient. However, sometimes a wordless relationship was perceived sufficient and considered a first step towards a verbal relationship.

    Conclusions

    Ambulance nurses experience that a caring relationship cannot and does not need to be prioritized in the acute stage. This uncovers a dichotomy approach to medical care versus caring relationships that exclude a holistic approach. Thus, patients’ emotional, existential and physical needs are not considered as equally important.

    Clinical relevance: It is important to stimulate reflection on core ethical nursing values, in training and simulation exercises among clinically active ambulance nurses.

    An Early Upper Palaeolithic Stone Tool Assemblage from Mughr El-Hamamah, Jordan: An Interim Report2019Ingår i: Journal of field archaeology, ISSN 0093-4690, E-ISSN 2042-4582Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Mughr el-Hamamah (Jordan) Layer B contains an Early Upper Palaeolithic stone tool assemblage dating to around 39–45 kya cal b.p. This assemblage is unusual in that it samples human forager activities around the ecotone between the Transjordanian Plateau and the palaeo-lake (Lake Lisan) that filled much of the Jordan Valley during Late Pleistocene times. This paper describes that assemblage, comparing it to other Levantine Upper Palaeolithic assemblages of equivalent antiquity. The Mughr el-Hamamah Layer B assemblage appears most similar to Early Ahmarian assemblages, but it departs from typical such assemblages in ways that may reflect local conditions’ influence on human activities carried out in and near the cave. Mughr el-Hamamah raises new questions about changes in residential mobility, off-site provisioning and foraging activity, and on-site task diversity in the Early Upper Palaeolithic period.

    An experimental study on smectites as nitrogen conveyors in subduction zones2019Ingår i: Applied Clay Science, ISSN 0169-1317, E-ISSN 1872-9053, Vol. 168, s. 409-420Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We performed high pressure and high temperature (HPHT) experiments on NH4-doped montmorillonite (similar to 2 wt % of NH4) under pressures of 2.5, 4.0, and 7.7 GPa and temperatures from 200 to 700 degrees C. Each experiment was analyzed with XRD, FTIR, CHN elemental analysis, and SEM in order to determine the NH4-Smectite phase changes and their morphology, and the presence of ammonium in the runs. Our results show that smectite can easily transport nitrogen, speciated as ammonium (NH4+), incorporated into the smectite interlayer in mildly reducing environments to deeper levels in the Earth through cold thermal regime subduction zones. NH4-Smectite transforms into NH4-enriched micaceous phase (tobelite) through a NH4+-enriched interlayered I/S phase in relatively low pressures and temperatures (around 2.5 GPa and 500 degrees C). Tobelite is stable until more extreme conditions (7.7 GPa and 700 degrees C), together with lesser amounts of buddingtonite (an ammonium-bearing feldspar) kyanite, and garnet. Our experiments also show the effect of nitrogen in the feldspar stability, as potassic and sodic feldspar are stable up to similar to 5 GPa, while buddingtonite, is observed to be stable up to 7.7 GPa. Nitrogen can return to the surface once the stability of these nitrogen-enriched minerals is reached due to pressure or temperature increasing.

    An inherent differentiation and system level assessment approach to inventory management: a safety stock method comparison2019Ingår i: The International Journal of Logistics Management, ISSN 0957-4903, Vol. 30, nr 2, s. 663-680Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose The purpose of this paper is to explain the effects of inherent differentiation and system level performance assessment in inventory management. This is done by comparing the performance of two common safety stock methods, by considering the methods' inherent differentiation and item group-levelperformance effects.

    Design/methodology/approach Due to the lack of analytical relationships between the two methods, the analysis is based on event-driven simulations. Data are collected from eight different case companies. Findings explain the importance of assessing safety stock performance for groups of items and not for individual items, as is common in academic studies. It explains how the methods' inherent differentiation and planning environment characteristics affect the relative performances of the two safety stock methods. 

    Findings The study explains the importance of assessing performance of safety stock methods on a system-level, rather than on item-level measures. It explains why the demand fill-rate method has a negative impact on the performance for groups of items, while the number-of-days method has a positive impact. The study also explains how the group-level safety stock performance is affected by five demand data characteristics. 

    Research limitations/implications The study explains the importance of assessing performance of safety stock methods on a system-level, rather than on item-level measures. It explains why the demand fill-rate method has a negative impact on the performance for groups of items, while the number-of-days method has a positive impact. The study also explains how the group-level safety stock performance is affected by five demand data characteristics. 

    Practical implications Understanding the necessity of system level assessment of safety stock performance, how methods inherently differentiate service levels, and how demand characteristics affect methods' performance can guide the choice of safety stock methods in companies. 

    Originality/value No research on the characteristics of the number-of-days safety stock method, any assessment of differentiation characteristics of and comparison with the demand fill-rate method, has been published. The variable inherent differentiation is also introduced and defined.

    An interdisciplinary perspective on gamification: mechanics, psychological mediators and outcomes2019Ingår i: INTERNATIONAL JOURNAL OF SERIOUS GAMES, E-ISSN 2384-8766, Vol. 6, nr 1, s. 3-26Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    As gamification literature has matured, the gap between how different domains apply the theory has widened. This has positioned gamification as being more dependent on context, rather than being an independent theory per se. To address this notion, three concepts are identified as being central for how the designergamifies a process. These are mechanics, psychologicalmediators and desired outcomes. Following this logic, a review was conducted using 79(n) articles across seven disciplines, namely health and wellness, crowdsourcing, sustainability, computer science, software development, business, and tourism. The findings highlighted potential relationships between several concepts when gamifying a situation, context, service or/and process.This research presents an alternative and uniform perspective on the broad gamification research to better understand how gamification functions and can be employed to impact various outcomes. Furthermore, this research contributes to this rather eclectic domain, presenting a more categorized view in showing domain-specific mechanics and how these can be employed for empirical testing.Lastly, the conceptual model can be modified, employed and adjusted to investigate various effects of gamification on outcomes.

    Analysis of tweets about football: 2013 and 2018 leagues in Turkey2019Ingår i: Behavior and Information Technology, ISSN 0144-929X, E-ISSN 1362-3001, Vol. 38, nr 9, s. 887-899Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Football has recently developed into a unique sector with complex management and marketing functions, where novel communication technologies are employed. In this paper, we aim to contribute to the numerous fields involving emerging European sports marketing literature, social media analytics, and digital consumer behaviour. Our purpose is to explore Twitter use related with football by analysing real-time streamed data in offering a longitudinal perspective by focusing on 2013 and 2018 leagues in Turkey via the use of social media analytics framework. Retrieved dataset involved randomly selected publicly available 370 thousand and 6.8 million real-time tweets in 2013 and 2018 leagues, respectively. We report that majority of tweets about the football was posted within the three-hour window before the match independent of the match result and the importance of the result. Moreover, pre-match tweeting volume was almost a crystal ball signalling match winning. Our findings are valuable for sports managers and marketers where some key suggestions provided are to involve particular contexts of winning or losing in their after-match marketing plans, to value weekdays as much as the weekends, and to utilise the after-work prime time of social media engagement.

    Analytics-driven digital platform for regional growth and development: a case study from Norway2019Ingår i: ICDS 2019, The Thirteenth International Conference on Digital Society and eGovernments / [ed] Lasse Berntzen, International Academy, Research and Industry Association (IARIA), 2019, s. 56-62, artikel-id icds_2019_3_30_10048Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this paper, we present the growth barometer (Vekstbarometer in Norwegian), which is a digital platform that provides the development trends in the regional context in a visual and user-friendly way. The platform is developed to use open data from different sources that is presented mainly in five main groups: goals, premises or prerequisites for growth, industries, growth, and expectations. Furthermore, it also helps to improve decision-making and transparency, as well as provide new knowledge for research and society. The platform uses sensitive and non-sensitive open data. In contrast to other similar digital platforms from Norway, where the data is presented as raw data or with basic level of presentations, our platform is advantageous since it provides a range of options for visualization that makes the statistics more comprehensive.

    Analyzing the Evolution of JavaScript Applications2019Ingår i: Proceedings of the 14th International Conference on Evaluation of Novel Approaches to Software Engineering - Volume 1: ENASE, SciTePress, 2019, Vol. 1, s. 359-366Konferensbidrag (Refereegranskat)
    Abstract [en]

    Software evolution analysis can shed light on various aspects of software development and maintenance. Up to date, there is little empirical evidence on the evolution of JavaScript (JS) applications in terms of maintainability and changeability, even though JavaScript is among the most popular scripting languages for front-end web applications. In this study, we investigate JS applications’ quality and changeability trends over time by examining the relevant Laws of Lehman. We analyzed over 7,500 releases of JS applications and reached some interesting conclusions. The results show that JS applications continuously change and grow, there are no clear signs of quality degradation while the complexity remains the same over time, despite the fact that the understandability of the code deteriorates.

    Anaphoric Reference to Quantified Expressions in Swedish2019Ingår i: Journal of Psycholinguistic Research, ISSN 0090-6905, E-ISSN 1573-6555, Vol. 48, nr 3, s. 551-568Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper presents the results from two studies on anaphoric reference to quantifying expressions (QEs) in Swedish, contributing to the current cross-linguistic discussion on this issue. For English it has been shown that the polarity of the QE (positive vs negative) determines the anaphoric set reference (to the referens set, REFSET, or to the complement set, COMPSET), while for Spanish it has been claimed that while REFSET interpretation is the default, the relative sizes of the two sets (REFSET and COMPSET) also matters. In Experiment 1, a semantic plausibility study. The results showed that for positive QEs, anaphoric reference can only be to the REFSET, while for negative QEs, it can only be to the COMPSET. Unlike in English and Spanish, REFSET continuations were categorically ruled out for negative QEs. To investigate whether the internal differences between QEs could be explained in terms of set size, we conducted Experiment 2, an estimation task. The results from this experiment showed that the size of the REFSET relative to the COMPSET was not a determining factor.
