This study examines the relationship between social network size, innovation and firm performance among firewood producers in Norway. Moreover, it investigates how this relationship is affected both by the structure and variations in networks and by firm size and age. A questionnaire-based survey was sent to managers of firms (including one-person firms) in the firewood industry in Norway. A total of 645 usable replies were received, and the theoretical model was tested using structural equation modelling. The findings show that social network size has a positive effect on firm performance via innovation by firewood producers. Furthermore, the results show that firewood producers with fewer involved family members and more variation in occupation and entrepreneurial experience in their networks benefit more from larger social networks than other producers do.

Abstract
Shoot dieback disease of European ash caused by the ascomycete Hymenoscyphus pseudoalbidus threatens ash on a continental scale. A spore sampler placed in a diseased ash forest in Southern Norway, coupled with microscopy and DNA-based fungal species-specific real-time PCR assays, was employed to profile diurnal and within-season variation in infection pressure by ascospores of H. pseudoalbidus and the potentially co-existing non-pathogenic Hymenoscyphusalbidus. Hymenoscyphus pseudoalbidus was found to be predominant in the stand. Massive simultaneous liberation, by active discharge of pathogen ascospores in the morning, peaked in mid-Jul. to mid-Aug. Accumulation of pathogen DNA on leaflets of current-year leaves reached a high level plateau phase before appearance of autumn coloration, suggesting that pathogen establishment in leaves is terminated before the onset of leaf senescence.

Corporate social responsibility (CSR) is one of the ways through which companies gain legitimacy. However, CSR actions themselves are subject to public skepticism because of increased public awareness of greenwashing and scandalous corporate behavior. Legitimacy of CSR actions is indeed influenced by the actions of the company but also is rooted in the basic cultural values of a society and in the ideologies of evaluators. This study examines the legitimacy of CSR actions of publicly traded forest products companies as compared to family-owned forest products companies. Results indicate a lower legitimacy for CSR actions of publicly traded companies than for family-owned companies. The study also examines the effect of social responsibility orientation (SRO) of evaluators on the legitimacy accorded to companies’ CSR actions. We found that SRO was negatively associated with legitimacy, especially for women. Perceived profitability of companies was negatively associated with legitimacy of CSR actions for publicly traded but not for family-owned companies.

There is a growing demand for reliable information about land cover and land resources. The Norwegian area frame survey of land cover and outfield land resources (AR18X18) is a response to this demand. AR18X18 provides unbiased land cover and land resource statistics and constitutes a baseline for studying changes in outfield land resources in Norway and a framework for a national land resource accounting system for the outfields. The area frame survey uses a systematic sampling technique with 0.9 km2 sample plots at 18 km intervals. A complete wall-to-wall land cover map of an entire plot surveyed is obtained in situ by a team of fieldworkers equipped with aerial photographs. The use of sample plots with extended coverage (0.9 km2) ensures that the survey also deals with local variation, thus strengthening the estimates well beyond simple point sampling. The article documents the methodology used in the survey, followed by a discussion of issues raised by the choice of methodology. These issues include the problem of calculating uncertainty and a confidence interval for the estimates, the focus on common rather than rare land cover categories, and the prospect of downscaling the results in order to obtain statistics for subnational regions.
