- Alluvial fan-like landforms have been identified on Mars. Since alluvial fans are recorders of processes that are sensitive to climatic conditions, the investigation of possible Martian fans can reveal information about the planet`s climate. In lieu of direct observations of active depositional processes on Martian fans, comparisons with terrestrial analogues can constrain models of Martian fan formation derived from remote sensing data. Since present-day Mars is cold and dry, alluvial fans formed in cold deserts should be considered as useful analogues. The probably closest climatic analogue to Mars on Earth are the Antarctic Dry Valleys , but polar deserts can also be found in the Arctic. We report on our field work in summer 2008 and a simultaneous flight campaign with an airborne version (HRSC-AX) of the High Resolution Stereo Camera (HRSC) onboard Mars Express. The results are compared with measurements of Martian fans, based on HRSC DEM.

Periglacial landscapes on Svalbard: Terrestrial analogs for cold-climate landforms on Mars
- 2011

Tidskriftsartikel (refereegranskat)abstract
- We present landforms on Svalbard (Norway) as terrestrial analogs for possible Martian periglacial surface features. While there are closer climatic analogs for Mars, e.g., the Antarctic Dry Valleys, Svalbard has unique advantages that make it a very useful study area. Svalbard is easily accessible and offers a periglacial landscape where many different landforms can be encountered in close spatial proximity. These landforms include thermal contraction cracks, slope stripes, rock glaciers, protalus ramparts, and pingos, all of which have close morphological analogs on Mars. The combination of remotesensing data, in particular images and digital elevation models, with field work is a promising approach in analog studies and facilitates acquisition of fi rst-hand experience with permafrost environments. Based on the morphological ambiguity of certain landforms such as pingos, we recommend that Martian cold-climate landforms should not be investigated in isolation, but as part of a landscape system in a geological context.

Svalbard (Norway) as a terrestrial analogue for Martian landforms: Results on

Konferensbidrag (refereegranskat)abstract
- Small alluvial fan-like landforms have been observed on Mars in association with recent gullies. Such fans are relatively small (km-scale) when compared to large alluvial fans on Mars, which can reach dimensions of tens of kilometers. The small fans are part of an erosion-transportsedimentation system (alcove-channel-apron). Morphologically very similar systems can be studied on Svalbard (Norway), which is a cold and dry polar desert and, therefore, a potentially useful terrestrial analogue for Mars` climate and climaterelated landforms. Here we give an update on our field work in summer 2008 and a simultaneous flight campaign with an airborne version (HRSCAX) of the High Resolution Stereo Camera (HRSC) onboard Mars Express. We also present very preliminary results from the field campaign in summer 2009.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND:: Nurses' attitudes toward caring for dying persons need to be explored. The Frommelt Attitude Toward Care of the Dying (FATCOD) scale has not previously been used in Swedish language. OBJECTIVES:: The objectives of this study were to compare FATCOD scores among Swedish nurses and nursing students with those from other languages, to explore the existence of 2 subscales, and to evaluate influences of experiences on attitudes toward care of dying patients. METHODS:: A descriptive, cross-sectional, and predictive design was used. The FATCOD scores of Swedish nurses from hospice, oncology, surgery clinics, and palliative home care and nursing students were compared with published scores from the United States, Israel, and Japan. Descriptive statistics, t tests, and factor and regression analyses were used. RESULTS:: The sample consisted of 213 persons: 71 registered nurses, 42 enrolled nurses, and 100 nursing students. Swedish FATCOD mean scores did not differ from published means from the United States and Israel, but were significantly more positive than Japanese means. In line with Japanese studies, factor analyses yielded a 2-factor solution. Total FATCOD and subscales had low Cronbach α's. Hospice and palliative team nurses were more positive than oncology and surgery nurses to care for dying patients. CONCLUSIONS:: Although our results suggest that the Swedish FATCOD may comprise 2 distinct scales, the total scale may be the most adequate and applicable for use in Sweden. Professional experience was associated with nurses' attitudes toward caring for dying patients. IMPLICATION FOR PRACTICE:: Care culture might influence nurses' attitudes toward caring for dying patients; the benefits of education need to be explored.

POSSIBLE FREEZE AND THAW LANDFROMS ON HIGH-LATITUDE SLOPES ON MARS: INSIGHTS FROM TERRESTRIAL ANALOGS IN SPITSBERGEN, SVALBARD.
- 2011

Konferensbidrag (refereegranskat)abstract
- Solifluction lobes are common slope features in Polar Regions on Earth where freeze and thaw processes occur. Mars is currently a cold and barren planet with its water resources locked up in ice caps, glaciers and ice-enriched permafrost. However, features resembling solifluction lobes have been observed on high-latitude slopes on Mars and in most, but not all, cases in close proximity to gullies. Lobes are found on steep inner crater walls and in planform they show striking resemblance to terrestrial solifluction lobes. These observations may point to a late phase in Mars history with transient melt water in local environments. In our study we have examined solifluction lobes on slopes in Svalbard in order to compare to the Martian lobate landforms. Specific questions we address are: how widely distributed are these lobate landforms on Mars and how do they relate to known ground-ice related landforms?

- Stripes and gelifluction lobes are common slope features in polar regions on Earth where freeze and thaw processes occur. Mars is currently a cold and barren planet with its water resources locked up as ice caps and ice-rich permafrost. However, features resembling stripes and gelifluction lobes have been observed on high-latitude slopes on Mars and in most, but not all, cases in close proximity to gullies. Stripe width typically ranges from ~50 cm to 1.5 m, and their orientation is consistently down slope, although it can not be excluded that it sometimes slightly deviates from the steepest topographic gradient. Lobes are found on steep inner crater walls and display similar dimensions as terrestrial gelifluction lobes. These observations may point to a late phase in Mars history with transient melt water in local niches. In our study we have examined sorted and non-sorted stripes as well as gelifluction lobes on slopes in Svalbard in order to test the working hypothesis of a freeze and thaw origin of the Martian landforms.

THE ORIGIN OF STRIPE-LIKE PATTERNS ON MARTIAN GULLY SLOPES; USING SVALBARD ADVENT VALLEY AS A MARS ANALOGUE.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Stripes are a common slope features in polar regions on Earth were active layer processes (freezing/thawing and gelifluction) occur. Their origin is most likely polygenic and closely related to frost crack plygons and sorted circles with the addition of a gravitational component. Stripes are either sorted or unsorted. Features resembling stripes have been observed on slopes on Mars with or without association with polygons. Due to the current temperature and pressure regime on Mars soil moisture and active layer processes are not likely to occur. However, in recent HiRISE images stripelike patterns can be observed in proximity to gullies . Stripe width typically ranges from ~50 cm to 1.5 m, and their orientation is consistently down slope, although it can not be excluded that it sometimes slightly deviates from the steepest topographic gradient. In our study we have examined sorted and nonsorted stripes on slopes in Svalbard in order to test the working hypothesis of an cryoturbation origin for the martian stripe-like patterns. In doing so we compare their morphological characteristics, settings, and slope to those on Mars.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)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.
