Non-compliance with iron supplementation consumption contributes to the high rate of anemia among adolescent girls in Indonesia. This study explores the barriers and enablers perceived by adolescent girls regarding regular iron supplement consumption. Using a qualitative design, eight focus group discussions (FGD) were conducted in Makassar and Padang involving 32 girls grade 8 and 9 from four junior high schools. Data on perceived barriers and enablers were collected using a social cognitive theory framework and analyzed thematically. The average age of the informants was 13,65±0,60 years. Although all participants received supplement at school, most did not consume them regularly. Key barriers include dislike of the taste and smell, parental prohibition negative experience consuming iron supplement, and the belief that iron supplements increase menstrual blood flow and volume. Enablers include self-awareness of the supplement’s benefits, trust in school-provided supplements, and positive support from parents and peers. Behavior change strategies are needed to address these barriers and strengthen supporting factors to improve iron supplementation consumption.

To contribute to small and medium enterprises (SMEs) sustainable transition into the circular economy, the study proposes the activation of organizational learning (OL) processes – denoted here as multi-level knowledge creation, transfer, and retention processes – as a key phase in introducing circular business models (CBMs) at SME and supply chain (SC) level. The research employs a mixed-method approach, using the focus group methodology to identify contextual elements impacting on CBM-related OL processes, and a survey-based evaluation to single out the most frequently used OL processes inside Italian construction SMEs. As main result, a CBM-oriented OL multi-level model offers a fine-grained understanding of contextual elements acting mutually as barriers and drivers for OL processes, as possible OL dynamics among them. The multi-level culture construct – composed of external stakeholders’, SC stakeholders’, and organizational culture – identify the key element to activate CBM-oriented OL processes. Main implications are related to the identification of cultural, structural, regulatory, and process contextual elements across the external, SC, and organizational levels, and their interrelation with applicable intraorganizational and interorganizational learning processes. The proposed model would contribute to an improved implementation of transitioning into the circular economy utilizing sustainable business models in the construction SMEs.
