An operational decision support tool for stump harvest
- 2011
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- A multi-criteria decision support tool was developed to optimise stump harvesting for energy in Sweden. The decision tool takes account of multiple, sometimes conflicting, criteria relating to stump harvest; energy and climate, economics, biodiversity, and soil and water. Data on harvested stems are used as primary input data in the tool. Such data are routinely collected in harvester computers. The tool effectively deals with mixed sets of data; quantitative harvest data are re-calculated to metric (e.g. stump biomass), and qualitative data (e.g. biodiversity implications) are incorporated. A digital terrain map derived from air-borne laser scanning provides basic data for estimating soil wetness, while digital maps of water courses, key habitats and protected areas, or other sensitive habitats, are used to identify potentially and practically harvestable stumps.In four sub-models, an index from 0 to 10 is calculated for each stump, with 0 representing ‘Not at all suitable’ and 10 ‘Highly suitable for extraction’. Through this, a stump of high value for wood-living species is assigned a low index in the biodiversity sub-model and a large, easily accessible stump is assigned a high index in the economic sub-model. When calculating the net index, the sub-indices can be weighted according to the preferences of the end-user.An energy and climate sub-model incorporates greenhouse gas (GHG) emissions from forest operations and the effect of advancing GHG emissions when stump biomass is incinerated instead of being left to decompose. In the economic sub-model the potential monetary return from each stump is calculated based on estimated revenue from harvested stump biomass and the costs of stump harvesting and forwarding operations (based on cost functions and GIS calculations of transport distances).The biodiversity sub-model considers four types of wood-dependent organisms (lichens, mosses, insects and fungi) in terms of their habitat requirements, vulnerability, sun exposure preferences, locality, etc. A panel of external experts has drawn up a grading scale of stump values for the different taxonomic groups. The proximity to key habitats and exposure to sunlight are derived from a spatial model.Soil and water issues are handled within a sub-model estimating the consequences for long-term soil fertility (nutrient cycling and soil compaction) and water (leaching of plant nutrients and mercury, and particle transport due to soil damage by heavy machinery).The tool offers the end-user possibilities to prioritise and plan for cost-effective stump harvesting, while minimising negative environmental impacts.

Samlingsverk (redaktörskap) (refereegranskat)abstract
- The conference Codex and Code: Aesthetics, Language and Politics in an Age of Digital Media (NorLit 2009)was held at the Royal Institute of Technology (KTH) in Stockholm, August 6–9, 2009. The conference was organized by the Nordic Association for Comparative Literature (NorLit); the Department of Culture and Communication, Linköping University; the School of Computer Science and Communication, Royal Institute of Technology (KTH); the Department of Comparative Literature, Stockholm University; the Department of Culture and Communication, Södertörn University College; and the Department of Comparative Literature, Uppsala University. The aim of the conference was to develop the study of Comparative Literature through Nordic collaboration both in its own discipline and in Modern Language and Cultural studies. As the title for the conference suggests, the principal question for the conference was the challenge that the study of literature encounters in an age of digitalization and globalization. It was our aim to encourage discussion of how literary studies respond to the ongoing changes in media and technology, politics and economy. Many have argued that the Humanities currently are in a state of crisis. We believe that the discipline seldom has found itself in such an interesting and fruitful historical moment. Several of these questions have surfaced during earlier media system changes, in particular during Romanticism and Modernism, which provided the conference with an historical frame. The conference Codex and Code also addressed questions of authenticity and originality, identity and gender, literary genres and reading practices, media and materiality, culture and popular culture, language and history, world literature, work aesthetics, translations, and canon formation. The conference Codex and Code wanted to stimulate interdisciplinary scholarly research of the literary in a broad sense. The conference was open to scholars in Comparative Literature and in Classical and Modern Languages, Aesthetics, Media and Communication studies, Film and Theatre studies, Philosophy and adjacent disciplines. The conference was organized around a number of thematic sessions in which researchers and scholars presented and discussed papers. The conference has received generous financial support from the Bank of Sweden Tercentenary Foundation, Magnus Bergwall foundation, Granholms foundation, Linköping University, School of Computer Science and Communication, Royal Institute of Technology, Svenska litteratursällskapet; the Swedish Academy, Swedish Science Council, and Vitterhetsakademien.

- A total of 24 patients, considerably disabled in daily activities by back pain, participated in an Equine Assisted Therapy (EAT) programme. The patients also had several health problems in addition to their current pain. The programme emphasised the principles of body awareness. The study is aimed at investigating not only whether symptom reduction would be achieved, but also at identifying qualities of EAT that were particularly beneficial for the patients' well being. The study was performed according to action research principles. The treatment reduced the pain and lessened other symptoms. The EAT also had an influence on the patients' self-image and a positive chain of effects was observed. The consequences were described according to four dimensions; the dimension of body awareness, competence, emotion and environment. The dimensions were interrelated having the simultaneous influence of a transition process and symptom reduction towards health.

- The protective effect of vitamin E supplements has been questioned, possibly because they often contain only alpha-tocopherol, and recent studies indicate that gamma-tocopherol also has important properties. The aim of this study was to investigate whether the levels of DNA lesions in middle-aged, overweight males could be reduced by consumption of low doses of an antioxidant supplement for six weeks, designed to imitate a balanced diet. The participants (n=60) were randomly divided into: placebo, single-, and double-dose groups. Genotoxic and oxidative DNA lesions in mononuclear cells were measured with the Comet assay, before and after supplement administration. Furthermore, a cell study was performed to investigate if pre-incubation of a human lung cell line (A549) with alpha- and gamma-tocopherol (5 and 50 microM for 23 hours) could protect against induced oxidative DNA lesions as measured by the Comet assay. The level of oxidative DNA lesions in the double-dose group was significantly lower than in the control group. Oxidative DNA lesions correlated only to changes in serum gamma-tocopherol, and not alpha-tocopherol. In the cell study, only gamma-tocopherol protected cells against induced oxidative DNA lesions. We therefore hypothesize that gamma-tocopheol rather than alpha-tocopherol is involved in reducing oxidative DNA lesions.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Is cancer related to hypertension and blood pressure? Do antihypertensive drugs promote cancer? Do antihypertensive drugs protect against cancer? We previously analysed the frequency of cardiovascular mortality and morbidity in elderly people who participated in the Swedish Trial in Old Patients with Hypertension 2 (STOP-Hypertension-2). We have also looked at the frequency of cancer in these patients. METHODS: We randomly assigned 6614 elderly patients with hypertension (mean age 76 years, median time of follow-up 5.3 years) to one of three treatment strategies: conventional drugs (diuretics or b-blockers), calcium antagonists, or ACE inhibitors. We matched the patients to the Swedish Cancer Registry and compared our findings with expected values based on age, sex, and calendar-year-specific reference frequencies for the general Swedish population. We also compared the number of cancers between the three treatment groups. FINDINGS: At baseline, 607 (9%) patients had previous malignant disease. Diagnoses were closely similar to the distribution of cancer types that might be seen in elderly patients. During follow-up, there were 625 new cases of cancer in 590 patients. The frequency of cancer did not differ significantly between the treatment strategies, including all cancers and those at individual sites. The standardised incidence ratios (SIRs) for all cancers were also close to unity: 0.92 (95% CI 0.80-1.06) for conventional drugs, 0.96 (0.83-1.10) for calcium antagonists, and 0.99 (0.86-1.13) for ACE inhibitors. INTERPRETATIONS: No difference in cancer risk was seen between patients randomly assigned to conventional drugs, calcium antagonists, or ACE inhibitors. Thus, the general message to the practising physician is that more attention should be given to getting the blood pressure down than to the risk of cancer.

Tidskriftsartikel (refereegranskat)abstract
- Quality of life data from randomized trials are lacking in older patients with metastatic colorectal cancer (mCRC). In the randomized NORDIC9-study, reduced-dose S1+oxaliplatin (SOx) showed superior efficacy compared to full-dose S1 monotherapy. We hypothesized that treatment with SOx does not result in inferior quality of life. Patients with mCRC aged ≥70 years and that were not a candidate for standard combination chemotherapy were included and randomly assigned to receive either S1 or SOx. The EORTC QLQ-C30 questionnaire was completed at baseline, after 9, and 18 weeks. The primary endpoint was global Quality of Life (QoL) at 9 weeks. For statistical analysis, a non-inferiority design was chosen applying linear mixed effects models for repeated measurements. The results were interpreted according to statistical significance and anchor-based, clinically relevant between-group minimally important differences (MID). A total of 160 patients aged (median (Interquartile range (IQR))) 78 years (76–81) were included. The QLQ-C30 questionnaire was completed by 150, 100, and 60 patients at baseline, at 9, and 18 weeks, respectively. The difference at 9 weeks in global QoL was 6.85 (95%CI—1.94; 15.65) and 7.37 (0.70; 14.05) in the physical functioning domain in favor of SOx exceeding the threshold for MID. At 18 weeks, the between-group MID in physical functioning was preserved. Dose-reduced combination chemotherapy may be recommended in vulnerable older patients with mCRC, rather than full-dose monotherapy.
