Tidskriftsartikel (övrigt vetenskapligt)abstract
- The characteristics and quantities of a large number of gaseous and particulate emission components during combustion in a residential wood log stove with variations in fuel, appliance and operational conditions were determined experimentally. The measurement campaign included CO, NOx, organic gaseous carbon (OGC), volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), total particulate matter (PMtot) as well as particle mass and number concentrations, size distributions and inorganic composition. CO varied in the range of 1100 to 7200 mg/MJfuel, while OGC varied from 210 to 3300 mg/MJfuel. Dominating VOCs were methane, followed by ethene, acetylene and benzene. Methane varied from 9 to 1600 mg/MJfuel. The non-methane volatile organic compound (NMVOC) emissions were in the range of 20-2300 mg/MJfuel. The PAHtot emissions varied from 0.8 to 220 mg/MJfuel, in most cases dominated by phenantrene, fluoranthene and pyrene. PMtot were in all cases dominated by fine particles and varied in the range 38-350 mg/MJfuel. The mass median particle diameters and the peak mobility diameters of the fine particles varied in the range 200-320 nm and 220-330 nm respectively and number concentrations in the range of 1-4×1013 particles/MJfuel. Air starved conditions, at high firing intensity, gave the highest emissions, especially for hydrocarbons. This type of conditions is seldom considered, though it may occur occasionally. The emissions from Swedish wood stoves, comparing a Swedish field study, are covered fairly well with the applied methodology, but other field studies reports considerably higher emissions especially for diluted particle sampling.

Refinement and psychometric reevaluation of the instrument Families' importance in nursing care : Nurses' attitudes
- 2011
-
Ingår i: Journal of Family Nursing. - Sage Publications, Inc. Sage Publications Ltd.. - 1074-8407. ; 17:3
-
Tidskriftsartikel (övrigt vetenskapligt)abstract
- The instrument Families’ Importance in Nursing Care–Nurses’ Attitudes (FINC-NA) was developed to measure nurses’ attitudes toward the importance of families in nursing care. The low variations in item responses, which affect the discrimination ability and unstable internal consistency, have been considered as limitations. The aim of this study was to refine and revalidate FINC-NA regarding score distribution, homogeneity, dimensionality, differential item functioning for gender, stability, and internal consistency. There were 246 registered nurses studying at advanced levels who answered the revised FINC-NA. The FINC-NA had five response alternatives. The findings showed that although some subscales still deviated from a normal distribution, the variability of the scores and the homogeneity was improved. In addition, the dimensionality was reproduced and minor problems with differential item functioning for gender were detected. All FINC-NA scales showed good reliability. The results allow the use of the revised FINC-NA in studies where an assessment of nurses’ attitudes toward families’ importance in nursing care is desired.

History of Participatory Media : Politics and Publics, 1750-2000
- 2011
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt)abstract
- This book argues for a historical perspective on issues relating to the notion of participatory media. Working from a broad concept of media – including essays on the 19th century press, early sound media, photography, exhibitions, television and the internet – the book offers a broad empirical approach to different modes of audience participation from the mid 19th century to the present. Using the insights from the historical case studies, the book also explores some of the key concepts in discussions on the politics of participation, arguing for a theoretical perspective sensitive to the asymmetries that characterize the distribution of agency in the relationship between media and users.Scholarly discussions on participatory media now occur in several fields. This book argues that all of these discussions are all too often obscured by a rhetoric of newness, assuming that participatory media is something unique in history, radical and revolutionary. By challenging the historiography implicit in this rhetoric, the book also engages in a discussion of issues of more general relevance to the multidisciplinary field of media history.

Significant improvement in quality of life of patients with incurable cancer after designation to a palliative homecare team
- 2010
-
Ingår i: European Journal of Cancer Care. - 0961-5423. ; 19:2, s. 243-250
-
Tidskriftsartikel (övrigt vetenskapligt)abstract
- The aims of this study were to describe and compare quality of life (QOL) before and after designation to a palliative homecare team (PHT) in patients with different cancer diagnoses and to identify pre-designation predictors of post-designation global QOL. We measured patients� QOL one week before designation and 11 days (median time) after with the Assessment of Quality of life at the End of Life (AQEL). Of 163 eligible patient 63 participated without attrition. Patients� QOL improved in the physical, psychological, medical and global areas. Six items significantly improved: hours recumbent during the day (p=.009), nausea (p=.008), anxiety (p=.007), getting hold of staff (p=.000), received care (p=.003) and global QOL (p=.023). Depression/low in mood (r=.55) and meaningfulness (r=.70) associated to global QOL. Furthermore, pain (p=.028) and meaningfulness (p=.028) predicted global QOL. In the existential area, it is important to further explore how meaningfulness is associated to and predicts global QOL.

A missense mutation in the aggrecan C-type lectin domain disrupts extracellular matrix interactions and causes dominant familial osteochondritis dissecans

Tidskriftsartikel (övrigt vetenskapligt)abstract
- Osteochondritis dissecans is a disorder in which fragments of articular cartilage and subchondral bone dislodge from the joint surface. We analyzed a five-generation family in which affected members had autosomal-dominant familial osteochondritis dissecans. A genome-wide linkage analysis identified aggrecan (ACAN) as a prime candidate gene for the disorder. Sequence analysis of ACAN revealed heterozygosity for a missense mutation (c.6907G > A) in affected individuals, resulting in a p.V2303M amino acid substitution in the aggrecan G3 domain C-type lectin, which mediates interactions with other proteins in the cartilage extracellular matrix. Binding studies with recombinant mutated and wild-type G3 proteins showed loss of fibulin-1, fibulin-2, and tenascin-R interactions for the V2303M protein. Mass spectrometric analyses of aggrecan purified from patient cartilage verified that V2303M aggrecan is produced and present in the tissue. Our results provide a molecular mechanism for the etiology of familial osteochondritis dissecans and show the importance of the aggrecan C-type lectin interactions for cartilage function in vivo.

Forskningsöversikt (övrigt vetenskapligt)abstract
- Selective immunoglobulin A deficiency (IgAD) is the most common primary immunodeficiency in Caucasians. It has previously been suggested to be associated with a variety of concomitant autoimmune diseases. In this review, we present data on the prevalence of IgAD in patients with Graves disease (GD), systemic lupus erythematosus (SLE), type 1 diabetes (T1D). celiac disease (CD), myasthenia gravis (MG) and rheumatoid arthritis (RA) on the basis of both our own recent large-scale screening results and literature data. Genetic factors are important for the development of both IgAD and various autoimmune disorders, including GD, SLE, T1D, CD, MG and RA, and a strong association with the major histocompatibility complex (MHC) region has been reported. In addition, non-MHC genes, such as interferon-induced helicase 1 (IFH1) and c-type lectin domain family 16, member A (CLEC16A), are also associated with the development of IgAD and some of the above diseases. This indicates a possible common genetic background. In this review, we present suggestive evidence for a shared genetic predisposition between these disorders.

The slow and fast components of postural sway in chronic neck pain
- 2011

Tidskriftsartikel (övrigt vetenskapligt)abstract
- Background: Several studies have reported altered postural control in people with neck pain. The aim of this study was to increase the understanding of the nature of altered postural control in neck pain by studying the slow and fast components of body sway. Methods: Subjects with whiplash associated disorders (WAD, n = 21) and chronic non-specific neck pain (NS, n = 24) were compared to healthy controls (CON, n = 21) in this cross-sectional study. The magnitudes of the slow and fast sway components were assessed in Rhomberg quiet stance for 30 s on a force plate with eyes closed. We also investigated associations between postural sway and symptoms, self-ratings of functioning and kinesiophobia. Results: Increased magnitude of the slow sway component was found in WAD, but not in NS. Greater magnitude of the slow component in WAD was associated with poorer physical functioning, including balance disturbances, and more severe sensory symptoms. Conclusions: Increased magnitude of the slow sway component implies an aberration in sensory feedback or processing of sensory information in WAD. The associations between postural sway and self-rated characteristics support the clinical validity of the test. Further investigation into NS, involving a longer test time is warranted
