Quality-assurance of heat-flow data: the new structure and evaluation scheme of the IHFC Global Heat Flow Database
Sven Fuchs, Ben Norden, Florian Neumann, Norbert Kaul, Akiko Tanaka, Ilmo T. Kukkonen, Christophe Pascal, Rodolfo Christiansen, Gianluca Gola, Dušan Rajver, 2023, original scientific article

Abstract: Since 1963, the International Heat Flow Commission has been fostering the compilation of the Global Heat Flow Database to provide reliable heat-flow data. Over time, techniques and methodologies evolved, calling for a reorganization of the database structure and for a reassessment of stored heat-flow data. Here, we provide the results of a collaborative, community-driven approach to set-up a new, quality-approved global heat-flow database. We present background information on how heat-flow is determined and how this important thermal parameter could be systematically evaluated. The latter requires appropriate documentation of metadata to allow the application of a consistent evaluation scheme. The knowledge of basic data (name and coordinates of the site, depth range of temperature measurements, etc.), details on temperature and thermal-conductivity data and possible perturbing effects need to be given. The proposed heat-flow quality evaluation scheme can discriminate between different quality aspects affecting heat flow: numerical uncertainties, methodological uncertainties, and environmental effects. The resulting quality codes allow the evaluation of every stored heat-flow data entry. If mandatory basic data are missing, the entry is marked accordingly. In cases where more than one heat-flow determination is presented for one specific site, and all of them are considered for the site, the poorest evaluation score is inherited to the site level. The required data and the proposed scheme are presented in this paper. Due to the requirements of the newly developed evaluation scheme, the database structure as presented in 2021 has been updated and is available in the appendix of this paper. The new quality scheme will allow a comprehensible evaluation of the stored heat-flow data for the first time.

Social context as a pillar of sustainable forest management - a Slovenian case
Nevenka Bogataj, 2009, original scientific article

Abstract: Social context as more or less neglected field of sustainable development is crucial for the implementation of forest management measures. We can consider it as a basis to cope with (changing) structure characteristics. Realisation of public services, which we face when coping with economic crisis, might take this into consideration. The Forest Service network serves as a scanner of needs in their social context. It is also a respondent to local specifics in the form of forest management measures. Evidence of research on the social research in Slovenian forestry is weak, although not non-existent. We tested asystem approach, a structuring method of general public. Segmentation, a method presented, is generally known in marketing and has not been used in Slovenian forestry up to now. The two-step clustering analysis of quantitative data gathered with an inquiry of study circles (form of community learning) was used and is described herewith. The results show three general value based segments of study circle participants. The role of Slovenian foresty is changing and is not independent of its dynamic and colourful social contexts, Recognition of the society structure and dynamics may contribute to the rationalisation of organisational models during the crisis period. Hoewer, grounded actualisation of recent organisational models is possible only by considering priorities of the society's segments. We conclude with suggestion for more R&D engagement in the social pillar of multifunctional forest management, in particular as the Slovenian social context is defined by dominance of private property and forest owners' ageing, which are far from being analysed and responded to.
