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.

Abstract
There is a need for monitoring methods for forest volume, biomass and carbon based on satellite remote sensing. In the present study we tested interferometric X-band SAR (InSAR) from the Tandem-X mission. The aim of the study was to describe how accurate volume and biomass could be estimated from InSAR height and test whether the relationships were curvilinear or not. The study area was a spruce dominated forest in southeast Norway. We selected 28 stands in which we established 192 circular sample plots of 250 m2, accurately positioned by a Differential Global Positioning System (dGPS). Plot level data on stem volume and aboveground biomass were derived from field inventory. Stem volume ranged fromzero to 596 m3/ha, and aboveground biomass up to 338 t/ha.We generated 2 Digital Surface Models (DSMs) fromInSAR processing of two co-registered, HH-polarized TanDEM-X image pairs – one ascending and one descending pair.We used a Digital TerrainModel (DTM) from airborne laser scanning (ALS) as a reference and derived a 10 m × 10 m Canopy Height Model (CHM), or InSAR height model. We assigned each plot to the nearest 10 m × 10 m InSAR height pixel. We applied a nonlinear, mixed model for the volume and biomass modeling, and from a full model we removed effects with a backward stepwise approach. InSAR heightwas proportional to volume and aboveground biomass, where a 1 m increase in InSAR height corresponded to a volume increase of 23 m3/ha and a biomass increase of 14 t/ha. Root Mean Square Error (RMSE) values were 43–44% at the plot level and 19–20% at the stand level.
