  • SNARE proteins mediate fusion between cytosolic lipid droplets and are implicated in insulin sensitivity.
  • 2007
  • Ingår i: Nature cell biology. - 1465-7392. ; 9:11, s. 1286-93
  • Tidskriftsartikel (refereegranskat)abstract
    • The accumulation of cytosolic lipid droplets in muscle and liver cells has been linked to the development of insulin resistance and type 2 diabetes. Such droplets are formed as small structures that increase in size through fusion, a process that is dependent on intact microtubules and the motor protein dynein. Approximately 15% of all droplets are involved in fusion processes at a given time. Here, we show that lipid droplets are associated with proteins involved in fusion processes in the cell: NSF (N-ethylmaleimide-sensitive-factor), alpha-SNAP (soluble NSF attachment protein) and the SNAREs (SNAP receptors), SNAP23 (synaptosomal-associated protein of 23 kDa), syntaxin-5 and VAMP4 (vesicle-associated membrane protein 4). Knockdown of the genes for SNAP23, syntaxin-5 or VAMP4, or microinjection of a dominant-negative mutant of alpha-SNAP, decreases the rate of fusion and the size of the lipid droplets. Thus, the SNARE system seems to have an important role in lipid droplet fusion. We also show that oleic acid treatment decreases the insulin sensitivity of heart muscle cells, and this sensitivity is completely restored by transfection with SNAP23. Thus, SNAP23 might be a link between insulin sensitivity and the inflow of fatty acids to the cell.

  • Seasonal employees' intention to return and do more than expected
  • 2012
  • Ingår i: Service Industries Journal. - 0264-2069. ; 32:12, s. 1957-1972
  • Tidskriftsartikel (refereegranskat)abstract
    • Seasonal employment is important in the service industries. Having motivated and satisfied employees is fundamental when front-line employees play a key role for the customers' perceived service quality. Seasonal work differs from permanent employment in many aspects and if managed properly, this could be a competitive advantage and contribute to the success of an organization. This study focuses on seasonal employees' intention to return and to do more than expected at work as well as the relationships between certain motivational factors and job satisfaction. A survey was carried out at four ski resorts with 477 respondents. Correlation and regression analyses indicate that job satisfaction influences the intention to return but does not have a strong influence on organizational citizenship behaviour (i.e. doing more than expected at work). The results improve our understanding of seasonal workers' motivation and behaviour. The concluding part discusses managerial implications.

  • Commensurability and sustainability: Triple impact assessments of a tourism event
  • 2013
  • Ingår i: Tourism Management. - 0261-5177 .- 1879-3193. ; 37, s. 99-109
  • Tidskriftsartikel (refereegranskat)abstract
    • In this study, a model for measuring impacts of a tourist event from sustainability perspectives and in a common monetary metric is developed. The aim is to achieve commensurability. The proposed model is tested on a three-day music festival and the results demonstrate a possibility to produce a sustainability impact analysis in a uniform metric. Measured in monetary terms, socio-cultural impacts carry weight just as economic impacts do whereas environmental impacts have little importance for the total assessment. This illustrates how the low market value of emission rights make environmental concerns negligible from an economic perspective. Finally, issues related to scope of the assessment, commensurability and opportunity cost are discussed and possibilities for future studies are suggested. (C) 2013 Elsevier Ltd. All rights reserved.

  • Estimating Use and Non-use Values of a Music Festival
  • 2012
  • Ingår i: Scandinavian Journal of Hospitality and Tourism. - 1502-2250. ; 12:3, s. 215-231
  • Tidskriftsartikel (refereegranskat)abstract
    • Impacts of a music festival may appear in many forms and research in the area of impact assessments is at present developing wider perspectives than being limited to economic impact assessments. Concepts like social, cultural and environmental impacts are now appropriate and traditional cost–benefit analysis is regaining momentum. The purpose of this study was first, to discuss how the value of a festival can be assessed and understood within a cost–benefit framework. Second, it was to evaluate a Scandinavian music festival in terms of Use and Non-use values by the contingent valuation method. The results illustrate the implications of a wider perspective regarding the impacts of a festival. Use value, representing the core experience, is the largest value (€7.4 million) but Non-use value is also important (€3 million). The latter includes the perceived value of externalities such as socio-cultural and environmental impacts which are highly relevant from a sustainability perspective. One conclusion is that Use and Non-use values within a cost–benefit framework can help managers and researchers understand value creation of festivals better.

  • Event portfolios: asset value, risk and returns
  • 2017
  • Ingår i: International Journal of Event and Festival Management. - 1758-2954. ; 8:3, s. 226-243
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: The research question addressed is whether an event portfolio analysis rooted in financial portfolio theory can yield meaningful insights to complement two approaches to event portfolios. The first approach is extrinsic and rooted in economic impact analysis where events need to demonstrate a financial return on investment. In the second approach events are valued ally, with every event having inherent value and the entire portfolio being valued for its synergistic effects and contribution to social and cultural goals. The paper aims to discuss these issues. Design/methodology/approach: Data from visitors to four events in the Sunshine Coast region of Australia are analyzed to illustrate key points, including the notion of “efficient frontier.” Findings: Conceptual development includes an examination of extrinsic and intrinsic perspectives on portfolios, ways to define and measure value, returns, risk, and portfolio management strategies. In the conclusions a number of research questions are raised, and it is argued that the two approaches to value event portfolios can be combined. Research limitations/implications: Only four events were studied, in one Australian local authority. The sample of residents who responded to a questionnaire was biased in terms of age, education and gender. Social implications: Authorities funding events and developing event portfolios for multiple reasons can benefit from more rigorous analysis of the value created. Originality/value: This analysis and conceptual development advances the discourse on portfolio theory applied to event management and event tourism. © 2017, © Emerald Publishing Limited.

  • Experience accounting : an accounting system that is relevant for the production of restaurant experiences
  • 2009
  • Ingår i: Service Industries Journal. - Routledge. - 0264-2069. ; 29:10, s. 1377-1396
  • Tidskriftsartikel (refereegranskat)abstract
    • Restaurants are clearly part of the experience industry but managers get little information and support from the accounting system in their efforts to create memorable meal experiences for their customers. The objective of this study is to empirically assess how an accounting system can be better aligned with the production of customer experiences. First, total costs are allocated to the production of four major types of experiences in a restaurant: basic food, culinary finesse, atmosphere, and service. This is followed by an analysis of customer evaluations of a meal experience categorised into the same four components. The study is based on empirical accounting data from three restaurants and an explorative study of how their customers evaluate an ideal as well as an actual meal experience they had in that restaurant. Experience evaluations are made in monetary terms, using the contingent valuation method, and the value of an experience can be compared with the cost of producing it. The analysis of the production cost compared with the value created indicate that, on average, the restaurants need to reallocate resources from service and basic food expenses to invest in the interior atmosphere of the restaurant to meet customer expectations.

  • Exploring Factors that Influence Event Sponsorship
  • 2011
  • Ingår i: Management Culture in the 21st Century. Proceedings of the European Academy of Management 11th Annual Meeting. - 978-9985-9824-7-1
  • Konferensbidrag (refereegranskat)abstract
    • This article contributes to sponsorship research as well as to event management theory and practice by systematically examining a number of factors that influence grant and sponsorship revenue for events (festivals). Data from 260 festival managers in Australia, Norway, Sweden and UK are compared with respect to their events’ revenue sources, ownership and other factors thought to influence revenue. Statistical tests reveal that event size (i.e., attendance), professionalism (as measured by staff numbers) and the "fit" between event and sponsor (as measured by type of event correlated with sponsor type and grant sources) significantly affect event revenue, and a number of practical management implications are discussed. Future research needs and theory development are discussed in the conclusions, focused on a new set of propositions derived from the analysis.
