Abstract
Peer support services have been established in several professions to help individuals cope with challenging work and life situations. Using the medical profession as an example, we have qualitatively studied physicians’ experiences of peer support. We conducted interviews with 12 physicians shortly after they had attended peer support and 12 months later. We analysed the interviews using systematic text condensation. We then reanalysed each pair of interviews (baseline and follow-up) using Schein’s model to further deepen the analytical insights. The results show that the professional medical role can evolve. Peer support helped the individual physician to become aware of, acknowledge and adjust to how unwritten rules within the medical culture had formed a non-sustainable professional role. Peer support can facilitate changes at and outside work, as well as foster a willingness to seek treatment for self-care.
Abstract
For establishment and growth of newly planted seedlings it is essential to overcome environmental stress at the planting site. Adding the amino acid arginine at planting is a novel treatment aiming at increased establishment success, so far tested in a limited number of applied studies. We examined the effects of adding arginine-phosphate (arGrow®), mechanical site preparation (MSP), and planting time on survival and growth of Norway spruce and Scots pine seedlings in two field experiments in boreal southeastern Norway. After three growing seasons, survival for spring planted seedlings of both species was significantly better following MSP, while addition of arginine-phosphate did not have any effect. Autumn planted pine seedlings with MSP and arginine had higher survival and also larger diameter than spring planted ones with MSP but without arginine. Spruce and pine seedlings with MSP were taller and had larger diameter than those without MSP. For spring planted seedlings of both species, dry weight of roots and shoots was positively affected by MSP, but not by arginine. To conclude, arginine-phosphate had neutral to modestly positive effects on survival and growth, while MSP had clear positive effects. The effect of planting time varied with species.

NIBIO produces Green Structure Maps (GSM) for Norway that cover built-up areas, including cabin areas. GSM is a hybrid product based on information from remote sensing data and detailed national vector datasets such as roads, water, buildings, and land use. GSM contains 8 classes: Ground, Shrub, Tree, Grey, Road, Water, Building, and Agriculture. QGIS is excellently suited for visual control of GSM. Based on the size of the dataset (number of polygons), a significant random sample of each class is selected to check whether it is correctly classified. You can organize the map layers into different themes, set up QGIS with multiple map windows showing different themes and zoom levels, and use existing plugins to jump from polygon to polygon and compare with aerial images and code whether the classification is correct or not - quickly and efficiently. More comprehensive statistics can then be calculated, and the results can be compared against the requirements to determine if the GSM meets the standards.

Abstract
The successful introduction of new cultivars depends on the evaluation of complex parameters essential for the consumers, market, and fruit producers. A new scab-resistant apple cultivar, ‘Wuranda’ (SQ159/Natyra®/Magic Star® × Honeycrisp), recently introduced in Norway and managed under the name Fryd©, is prone to biennial bearing. Therefore, one of the first tasks, investigated in Southwestern Norway by the Norwegian Institute of Bioeconomy Research, NIBIO-Ullensvang in 2021–2024, was the establishment of optimal crop load level based on the combination of productivity, fruit quality, and return bloom. The apple cultivar Fryd (‘Wuranda’) was propagated on ‘M.9’ rootstock and planted in 2019. The trial was performed in the same orchard for four consecutive years, starting three years after planting. Crop load level affected average fruit mass but had no impact on cv. Fryd fruit quality parameters at harvest such as blush, ground color, firmness, soluble solid content, or starch degradation. Fruit size variation was diminished by crop load regulation, and most fruits fell into 2–3 grading classes. Crop load, not the yield per tree, was the determining factor for the return bloom. The optimal crop load level depended on the orchard age. To guarantee a regular bearing mode of cv. Fryd planted on M.9 rootstock at a 3.5 × 1 m distance and trained as slender spindle, crop load of 5.5–6 fruits cm−2 TCSA (trunk cross-sectional area) in the 3rd year, 7.5–8 fruits cm−2 TCSA in the 4th year, and 6.5–7 fruits cm−2 TCSA in the 5th year should be maintained.
Abstract
Plant-based meat analogues (PBMA) are expected to reduce environmental, health, and animal welfare challenges from the production and consumption of meat. This paper investigates PBMA consumption using three rounds of a survey. PBMA consumption in Norway increased from 2017 to 2019 but stagnated in 2022. Several food choice motives and socioeconomic factors affected consumption consistently across the survey rounds. Emphasizing the environment, animal welfare, and novelty were positively associated with PBMA consumption, while emphasizing familiarity and Norwegian origin were negatively associated. Younger, higher educated, urban, and vegetarian respondents were more likely to consume PBMA. Use of social media had a positive effect on the consumption for the total sample, but it was not stable across the survey rounds. Producers, marketers, and other policy makers could promote the environmental and animal welfare benefits along with the novelty aspects of PBMA. The use of domestic ingredients could also appeal to older and rural individuals who emphasize food familiarity.
