Users and producers : Online News as Mediated Participation
- 2017
-
Doctoral thesis (other academic/artistic)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.

In: Journal of Exercise Rehabilitation. - Seoul : Korean Society of Exercise Rehabilitation. - 2288-176X .- 2288-1778. ; 12:1, s. 21-28

Journal article (peer-reviewed)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.

Conference paper (peer-reviewed)abstract
- 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.

The Gap between Theory and Practice of Stakeholder Participation : The Case of Management of The Korle Lagoon, Ghana
- 2009
-
In: LEAD Journal. - 1746-5893. ; 5:1, s. 73-89
-
Journal article (peer-reviewed)abstract
- Participation of stakeholders at the local level is evolving as a mechanism to address complex environmental problems, not least water pollution. Participation has been used as a tool for the economic and social empowerment of settlements within the catchment of the Korle lagoon in Ghana, particularly residents of the Old Fadama community that live in proximity to the lagoon. Using direct observations and survey of stakeholder groups, the paper examines the structure and process of participation of stakeholders in Korle lagoon resource use and water policy formulation and implementation with regard to Korle Lagoon Ecological Restoration Project (KLERP). The results show that exclusion of stakeholders generates conflict and antagonism which hinders the implementation of water resource policy. Alliances of stakeholders in the participatory process have served as pressure points compelling government to negotiate with civil society on behalf of the community. In theory, participation holds promise to address conflict, however in practice, a number of factors that feed into conflict characterise the process of participation in this case, such as ineffective information flow in the community, agency-structure dynamics, historical antecedents among the ethnic groups and low-levels of communication. These gaps jointly undermine the full participation of the Old Fadama community in lagoon management.

Social and moral psychology of COVID-19 across 69 countries
- 2023
-
In: Scientific Data. - : NATURE PORTFOLIO. - 2052-4463. ; 10:1
-
Journal article (peer-reviewed)abstract
- The COVID-19 pandemic has affected all domains of human life, including the economic and social fabric of societies. One of the central strategies for managing public health throughout the pandemic has been through persuasive messaging and collective behaviour change. To help scholars better understand the social and moral psychology behind public health behaviour, we present a dataset comprising of 51,404 individuals from 69 countries. This dataset was collected for the International Collaboration on Social & Moral Psychology of COVID-19 project (ICSMP COVID-19). This social science survey invited participants around the world to complete a series of moral and psychological measures and public health attitudes about COVID-19 during an early phase of the COVID-19 pandemic (between April and June 2020). The survey included seven broad categories of questions: COVID-19 beliefs and compliance behaviours; identity and social attitudes; ideology; health and well-being; moral beliefs and motivation; personality traits; and demographic variables. We report both raw and cleaned data, along with all survey materials, data visualisations, and psychometric evaluations of key variables.

Maximal strength in one leg squat correlates with acceleration capacity and agility
- 2010
-
Conference paper (peer-reviewed)abstract
- INTRODUCTION: In many intermittent team sports capacities such as speed, agility and explosiveness are important for performance and are evaluated by sprint-, agility- and strength tests. Earlier studies have shown strong correlations between strength in the two leg squat exercise and sprint performance in various distances but not in sprint performance in agility. Studies evaluating squat strength predominantly perform tests on two legs even when they test athletes involved in intermittent sports where sprinting and agility are common features. Thus, the purpose of this study was to investigate the correlation between maximal strength in a one leg squat (Bulgarian split squat) and acceleration capacity in various sprint distances and agility.METHODS: The test group consisted of 19 men (mean age 24 ± 2 years ) with experience in intermittent team sports. Acceleration capacity was assessed by sprint tests at 5, 10 and 20 meters and agility was evaluated using the zigzag agility test. The timing was made using photocells (Muscle lab,Ergotest Technology,Norway). The Bulgarian split squat was performed in a smith machine with the barbell on the shoulders to a depth of 110 degrees between tibia and femur.RESULTS: The results show significant correlation between maximal strength in the Bulgarian split squat and sprint capacity in the 5 and 10 meter sprint test (Rp= -0,56; p<0.01) as well as the agility test. Maximal strength relative to bodyweight showed significant correlation with the 5 and 20 meter sprint (Rp=-0,62; p< 0,01) as well as the agility test. The zigzag agility test also showed significant correlation between all distances in the sprint tests (p<0.01).CONCLUSION: The results from this study show that there maximal strength in one leg correlate significantly with both acceleration capacity and agility. Implementing one leg exercises in the strength and conditioning routine can be useful for athletes in intermittent sports wanting to improve agility and short sprinting capacity. Further implications is that the Bulgarian split squat could be a more functional test for agility performance than the squat on two legs which predominantly is being used today.

Effect of Conditioning Regimen Dose Reduction in Obese Patients Undergoing Autologous Hematopoietic Cell Transplantation
- 2019
-
In: Biology of blood and marrow transplantation. - : Elsevier BV. - 1083-8791 .- 1523-6536. ; 25:3, s. 480-487
-
Journal article (peer-reviewed)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.

Active Learning for Dialogue Act Classification
- 2011. - 9
-
Conference paper (peer-reviewed)abstract
- Active learning techniques were employed for classification of dialogue acts over two dialogue corpora, the English human-human Switchboard corpus and the Spanish human-machine Dihana corpus. It is shown clearly that active learning improves on a baseline obtained through a passive learning approach to tagging the same data sets. An error reduction of 7% was obtained on Switchboard, while a factor 5 reduction in the amount of labeled data needed for classification was achieved on Dihana. The passive Support Vector Machine learner used as baseline in itself significantly improves the state of the art in dialogue act classification on both corpora. On Switchboard it gives a 31% error reduction compared to the previously best reported result.
