Users and producers : Online News as Mediated Participation
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this thesis is to illuminate principles that guide mediated participation, taking place through the interplay between users and news producers. Therefore, the study focuses both how spaces for participation are structured (by news producers) and those that exert participatory practices (news users). The research design thus has an approach that ties together analytical strands that previously have been studied separately. The research questions concern how the conditions comprising mediated participation – in terms of opportunities for users’ participatory practices – differ between (1a) various types of online news sites, and (1b) various types of news, as well as how users exercise participatory practices (2a) on various types of news sites, and (2b) in connection to various types of news. The last research question (3) concerns how users express the connection to news producers, through participatory practices within participatory spaces. The thesis includes four papers, that together answer the research questions by applying content and text analyses to various types of news sites (big city national, local rural area, morning broadsheets and evening tabloids) and its content: news articles and features for user participation, such as comments and sharing news through social media (i.e., Facebook and Twitter).The results show that users and news producers take diverging approaches to user participation adjacent to online news. This is illustrated by the fact that the categories of news that users are most often permitted to interact with, coincide precisely with the news that users tend to decline to interact with, while the news categories that users tend to interact with (when given the chance) occur comparatively sparse. The results also show that news producers are much more prone to permit users to share news through social media, than to permit them to comment news on the news site. Almost all news are made to permit users to share news through Facebook and Twitter, whereas commenting news is substantially more restricted, and even more so among big city national news sites than among local rural area news sites. When it concerns user practices, users share news on Facebook 20 times more often than they share news through Twitter or comment news on news sites. Tweeting news almost only occurs in news sites affiliated with big city national newspapers, and most prominently so when it concerns evening tabloids. This means (when controlling for differences in circulation) that commenting as a user practice tend to have a more local character than tweeting news, with its more national focus.The connection between users and news producers is shaped by the approach these groups of actors take to each other, under different circumstances. Sharing news through Facebook and commenting on news sites, are not interchangeable practices. Nor is tweeting news from a news site affiliated with national tabloid compared to from a local morning newspaper. And although it is well known from extant research that producers hold hesitant views concerning users’ influence over content, users also express distrust when it concerns how professional media practices allow various actors salience in the media. These ideas primarily concern “elites” versus “commoners”, differences between public service and commercial media, regulations and media, including roles, genres, and formats. These ideas also concern whether representational principles should guide media representation or if certain views should be excluded, whether journalists’ political views affect media performance, and how crime news should be presented in terms of what events are published and representations of victims and perpetrators. Overall, the thesis illustrates that there are connections between various forms of electronic communication (i.e., commenting and sharing news through Facebook and Twitter), and the specific contextual and social settings that news sites are embedded within, with its specific situated audience, shaping the connections between users and news producers.

Tidskriftsartikel (refereegranskat)abstract
- This study investigated the association between spinal alignment, mobility of the hips and the thoracic spine and low back pain in adolescent cross-country skiers. Cohort of 51 elite cross-country skiers from a cross-country skiing high school in Sweden participated in the study. Sagittal spinal alignment, active range of motion in flexion, extension and rotation of the thoracic spine as well as passive and active extension of the hips were measured. The participants also completed a questionnaire regarding training, competition, skiing technique and occurrence of low back pain. A simple linear regression was calculated to predict pain score based on thoraco-lumbar relation, with a significant (P<0.05) regression equation of y=-0.069x+2.280 (standard error of estimate, 0.034). Participants with greater lordosis than kyphosis were more likely to suffer from low back pain than subjects without this offset. Thoracic mobility and passive or active hip extension showed no correlation with low back pain. Sagittal spinal alignment seems to be related with low back pain among young elite cross-country skiers. This study shows that range of motion of the thoracic spine and hips do not have an effect on the prevalence of low back pain in this population.

- A Soft X-ray Laser (SXL) beamline utilising FEL technology is being designed for the Short Pulse Facility (SPF) at the MAX IV Laboratory. A conceptual design study has been started following on the scientific case already prepared in collaboration between several Swedish Universities and driven by a strong (Swedish) user demand. The baseline goal of the SXL beamline is to generate intense and short pulses in the range 1-5 nm (0.2-1 keV). The system is building on the MAX IV linac system, already today providing 100 fs 3 GeV and pulses compressed to 100 fs for other applications within the SPF. As a special feature we foresee a variety of pump-probe capabilities.

Tidskriftsartikel (refereegranskat)abstract
- Data are limited on whether to adjust high-dose chemotherapy before autologous hematopoietic cell transplant (autoHCT) in obese patients. This study explores the effects of dose adjustment on the outcomes of obese patients, defined as body mass index (BMI) ≥ 30 kg/m2. Dose adjustment was defined as a reduction in standard dosing ≥ 20%, based on ideal, reported dosing and actual weights. We included 2 groups of US patients who had received autoHCT between 2008 and 2014. Specifically, we included patients with multiple myeloma (MM, n = 1696) treated with high-dose melphalan and patients with Hodgkin or non-Hodgkin lymphomas (n = 781) who received carmustine, etoposide, cytarabine, and melphalan conditioning. Chemotherapy dose was adjusted in 1324 patients (78%) with MM and 608 patients (78%) with lymphoma. Age, sex, BMI, race, performance score, comorbidity index, and disease features (stage at diagnosis, disease status, and time to transplant) were similar between dose groups. In multivariate analyses for MM, adjusting for melphalan dose and for center effect had no impact on overall survival (P = .894) and treatment-related mortality (TRM) (P = .62), progression (P = .12), and progression-free survival (PFS; P = .178). In multivariate analyses for lymphoma, adjusting chemotherapy doses did not affect survival (P = .176), TRM (P = .802), relapse (P = .633), or PFS (P = .812). No center effect was observed in lymphoma. This study demonstrates that adjusting chemotherapy dose before autoHCT in obese patients with MM and lymphoma does not influence mortality. These results do not support adjusting chemotherapy dose in this population.

Evaluating measures of individual investors' expectations of risk and return
- 2017
-
Ingår i: Review of Behavioral Finance. - 1940-5979. ; 9:3, s. 206-226
-
Tidskriftsartikel (refereegranskat)abstract
- PurposeThe purpose of this paper is to measure individual investors’ expectations of risk and return and to evaluate different expectation measures.Design/methodology/approachThe authors measure individual investors’ expectations of risk and return regarding an index fund and two stocks using survey data on a random sample of individual investors in Sweden. The survey contains three different return and four different risk expectation measures. To evaluate the different expectation measures, three different evaluation perspectives are considered.FindingsThe risk expectations obtained from the different measures are positively correlated across respondents, but their average magnitudes differ considerably across measures. The return expectations are also positively correlated, and their magnitudes also differ, but to a lesser extent. Consequently, the same individual can express risk expectations that either underestimate or overestimate the forward risk, depending on the measure that is used. The variations in the expectations mainly relate to differences in the responses to the questions underlying the different measures, rather than to the methods used to obtain the expectations. The results from the evaluation of the measures indicate that the expectation measure proposed by Dominitz and Manski (2011) is the only measure for which it is possible to distinguish between individuals’ expectations, using all three of the evaluation perspectives.Originality/valueThis is, to the best of the authors’ knowledge, the first paper that evaluates different survey measures of individual investors’ expectations of risk and return.

Simulation Study of Power Limitation for City Trams
- 2016
-
Ingår i: Proceedings of the 11th ITS European Congress.
-
Konferensbidrag (refereegranskat)abstract
- In this paper, we describe a simulation study aimed at investigating whether a momentary limitation of the tram power-output can be effective in reducing current overload, while maintaining the tram performance at an acceptable level. The study was performed on a single-fed tram section in Gothenburg, Sweden. The simulation results indicate that an adaptive power output limitation, which is only activated when the current and current derivative is above certain limits, is effective in reducing current peaks, while still maintaining required tram performance. Thus, this method could be used to reduce or eliminate power failure on the tram net, without causing unacceptable tram delay.

- OBJECTIVES: To determine the combined effects of slow isokinetic resistance training and eccentric overload and compare it to traditional resistance training on strength, power, body composition and muscle hypertrophy in young ice hockey players.DESIGN: Experimental, randomized trial.METHODS: Twenty-two resistance-trained ice hockey players (18±1year) were assigned to either isokinetic resistance training and eccentric overload (ISO/ECC; n=11) or traditional resistance training (TRAD; n=11). Participants underwent supervised progressive resistance training for 8 weeks (2-3 sessions/week) involving lower body multiple-joint exercises (heavy squats and explosive jump squats). The ISO/ECC group performed their training using a computerized robotic engine system (1080 Quantum synchro, Sweden), whereas the TRAD group performed the same resistance exercises with isotonic loading. Before and after the intervention, participants were evaluated in 1RM back squat, loaded jump squats, sprint- and jump performance, body composition and muscle thickness using ultrasound measurement.RESULTS: Similar moderate increases in 1RM back squat and power output in the jump squats were found in both the ISO/ECC and TRAD groups (11-17%, P<0.01), whereas only the ISO/ECC group showed improvements in drop jump performance (9.8%, P=0.01). Moreover, similar trivial changes in body composition were observed in both groups, while only the ISO/ECC training group increased muscle thickness in the vastus intermedius (P=0.01) and rectus femoris muscles (P=0.03).CONCLUSIONS: Both modalities effectively increased maximal strength and power output, whereas isokinetic resistance training, combined with eccentric overload, improved drop jump performance and induced greater muscle hypertrophy than traditional training in young ice hockey players. © 2019 Sports Medicine Australia

Public Policies for Charging of Electric Vehicles inMultifamily Dwellings - A Case Study in Gothenburg
- 2017
-
Konferensbidrag (refereegranskat)abstract
- The most important location for charging of electric vehicles is nearby the household. Access to a charging point is in general possible for people who own their car park, but could be more complicated for residents in multifamily dwellings. A case study was conducted with the aim to develop a common strategy for charging of electric vehicles in the proximity of multifamily dwellings in the city of Gothenburg. The suggested policies align with the city's local aims and do not hinder future densification or high utilization of parking areas.
