- Sediments represent the main reservoir of mercury (Hg) in aquatic environments and may act as a source of Hg to aquatic food webs. Yet, accumulation routes of Hg from the sediment to benthic organisms are poorly constrained. We studied the bioaccumulation of inorganic and methylmercury (HgII and MeHg, respectively) from different geochemical pools of Hg into four groups of benthic invertebrates (amphipods, polychaetes, chironomids, and bivalves). The study was conducted using mesocosm experiments entailing the use of multiple isotopically enriched Hg tracers and simulation of estuarine systems with brackish water and sediment. We applied different loading regimes of nutrients and terrestrial organic matter and showed that the vertical localization and the chemical speciation of HgII and MeHg in the sediment, in combination with the diet composition of the invertebrates, consistently controlled the bioaccumulation of HgII and MeHg into the benthic organisms. Our results suggest a direct link between the concentration of MeHg in the pelagic planktonic food web and the concentration of MeHg in benthic amphipods and, to some extent, in bivalves. In contrast, the quantity of MeHg in benthic chironomids and polychaetes seems to be driven by MeHg accumulation via the benthic food web. Accounting for these geochemical and dietary drivers of Hg bioaccumulation in benthic invertebrates will be important to understand and predict Hg transfer between the benthic and the pelagic food web, under current and future environmental scenarios.

- Background: Optimal oxygen targets in patients resuscitated after cardiac arrest are uncertain. The primary aim of this study was to describe the values of partial pressure of oxygen values (PaO2) and the episodes of hypoxemia and hyperoxemia occurring within the first 72 h of mechanical ventilation in out of hospital cardiac arrest (OHCA) patients. The secondary aim was to evaluate the association of PaO2 with patients’ outcome. Methods: Preplanned secondary analysis of the targeted hypothermia versus targeted normothermia after OHCA (TTM2) trial. Arterial blood gases values were collected from randomization every 4 h for the first 32 h, and then, every 8 h until day 3. Hypoxemia was defined as PaO2 < 60 mmHg and severe hyperoxemia as PaO2 > 300 mmHg. Mortality and poor neurological outcome (defined according to modified Rankin scale) were collected at 6 months. Results: 1418 patients were included in the analysis. The mean age was 64 ± 14 years, and 292 patients (20.6%) were female. 24.9% of patients had at least one episode of hypoxemia, and 7.6% of patients had at least one episode of severe hyperoxemia. Both hypoxemia and hyperoxemia were independently associated with 6-month mortality, but not with poor neurological outcome. The best cutoff point associated with 6-month mortality for hypoxemia was 69 mmHg (Risk Ratio, RR = 1.009, 95% CI 0.93–1.09), and for hyperoxemia was 195 mmHg (RR = 1.006, 95% CI 0.95–1.06). The time exposure, i.e., the area under the curve (PaO2-AUC), for hyperoxemia was significantly associated with mortality (p = 0.003). Conclusions: In OHCA patients, both hypoxemia and hyperoxemia are associated with 6-months mortality, with an effect mediated by the timing exposure to high values of oxygen. Precise titration of oxygen levels should be considered in this group of patients. Trial registration: clinicaltrials.gov NCT02908308, Registered September 20, 2016.

- Purpose: The optimal ventilatory settings in patients after cardiac arrest and their association with outcome remain unclear. The aim of this study was to describe the ventilatory settings applied in the first 72 h of mechanical ventilation in patients after out-of-hospital cardiac arrest and their association with 6-month outcomes. Methods: Preplanned sub-analysis of the Target Temperature Management-2 trial. Clinical outcomes were mortality and functional status (assessed by the Modified Rankin Scale) 6 months after randomization. Results: A total of 1848 patients were included (mean age 64 [Standard Deviation, SD = 14] years). At 6 months, 950 (51%) patients were alive and 898 (49%) were dead. Median tidal volume (VT) was 7 (Interquartile range, IQR = 6.2–8.5) mL per Predicted Body Weight (PBW), positive end expiratory pressure (PEEP) was 7 (IQR = 5–9) cmH20, plateau pressure was 20 cmH20 (IQR = 17–23), driving pressure was 12 cmH20 (IQR = 10–15), mechanical power 16.2 J/min (IQR = 12.1–21.8), ventilatory ratio was 1.27 (IQR = 1.04–1.6), and respiratory rate was 17 breaths/minute (IQR = 14–20). Median partial pressure of oxygen was 87 mmHg (IQR = 75–105), and partial pressure of carbon dioxide was 40.5 mmHg (IQR = 36–45.7). Respiratory rate, driving pressure, and mechanical power were independently associated with 6-month mortality (omnibus p-values for their non-linear trajectories: p < 0.0001, p = 0.026, and p = 0.029, respectively). Respiratory rate and driving pressure were also independently associated with poor neurological outcome (odds ratio, OR = 1.035, 95% confidence interval, CI = 1.003–1.068, p = 0.030, and OR = 1.005, 95% CI = 1.001–1.036, p = 0.048). A composite formula calculated as [(4*driving pressure) + respiratory rate] was independently associated with mortality and poor neurological outcome. Conclusions: Protective ventilation strategies are commonly applied in patients after cardiac arrest. Ventilator settings in the first 72 h after hospital admission, in particular driving pressure and respiratory rate, may influence 6-month outcomes.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: This study aims to examine and compare the influence of the disposition to engage in engagement behaviors on physical and virtual engagement platforms, as well as the influence of these engagement behaviors on brand loyalty, value-in-use and word-of-mouth. Design/methodology/approach: Data were collected using a survey distributed to a random sample of 10,000 fans of five teams in the Swedish top-division of elite football. An exploratory factor analysis was performed to derive a distinction between prevalent platforms, scales were validated through a confirmatory factor analysis and structural equation modeling was used to test the research model. Findings: Customer disposition to engage with the sports team had a significant influence on customer engagement behaviors on both physical and virtual engagement platforms. However, engagement behaviors on virtual platforms were found to be more important than engagement behaviors on physical platforms for fostering brand loyalty and value-in-use. Practical implications: The results highlight the importance of engagement behaviors with a brand on virtual engagement platforms. Thus, brand managers should prioritize their presence on social media to generate the positive outcomes of customer engagement behaviors. Originality/value: By examining the effects of customer engagement behaviors on both physical and virtual engagement platforms, this study provides new insights to the emerging customer engagement literature.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: The purpose of this paper is to develop a holistic understanding of extant studies addressing the impact of commercialization on fans of elite sports. Design/methodology/approach: In doing this, the authors performed a structured review of 42 academic articles published between 1992 and 2020 that all focus on how fans respond and are affected by the commercialization of elite sports. Findings: The structured review shows that the impacts of commercialization on fans relate to four different themes. These are (1) fan identity, (2) fan attitudes, (3) fan emotions and (4) fan behaviours. However, the analysis also shows that research within each category is largely scattered, and more research within each category is needed. Originality/value: The paper highlights the complex and dynamic nature of commercialization. It presents a research agenda for future research and emphasizes a need to integrate the interests of several stakeholders when managing the impacts of elite sport commercialization.

Ungas röst : En studie om ungdomars valdeltagande 2018 och deras egna tankar om att delta i val
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Valdeltagandet är högt bland unga och följer ganska väl befolkningen i stort. Det finns dock en oroväckande klyfta i samhället, alla unga upplever inte att de har lika möjligheter att göra sin röst hörd. Unga med sämre socioekonomiska förutsättningar deltar i lägre utsträckning i val. Under samtal med unga träder också en allvarlig bild fram av att unga inte upplever att samhället finns till för dem eller att politiska företrädare inte lyssnar. De känner sig inte inkluderade.Den här rapporten visar att det spelar roll var unga växer upp och bor. Ungas socioekonomiska förutsättningar är tätt sammankopplade med valdeltagande. Det finns betydande skillnader i valdeltagande mellan olika områden i kommunerna i hela landet. Det visar att skillnader i social jämlikhet riskerar att leda till politisk ojämlikhet. De geografiska skillnaderna i valdeltagande pekar på att det finns behov av insatser som utjämnar skillnader i uppväxt- och levnadsvillkor. Alla unga ska ges likvärdiga förutsättningar, det ska inte spela någon roll var de bor.

20 Years of Nordic event and festival research: a review and future research agenda
- 2021
-
Ingår i: Scandinavian Journal of Hospitality and Tourism. - : Informa UK Limited. - 1502-2250 .- 1502-2269. ; 21:1, s. 49-59

Tidskriftsartikel (refereegranskat)abstract
- The research output during the last two decades suggests that events and festivals are of major importance for society both internationally and in a Nordic context. Existing literature, primarily published in a Nordic context, is reviewed and organized according to three broad areas: The event and festival consumer, the event or festival as organization and the effects and interrelationships of events and festivals with society. We discuss the contribution which Nordic research has made to the Nordic School and to international event and festival research and suggest a future research agenda focusing on methods, context and theories.
