Purpose This study aims to explore ways to enhance competitiveness of commercial lighting industry because of the growing digitally connected stakeholder community. Positive responses from stakeholders to recurring business interactions help build trust and formation of a community; value chains being one form of such trusted community. Because of the increasing trust, the effort to search right value chain partners diminishes, business interactions become less formal and transaction costs are reduced, thus increasing the competitiveness. Design/methodology/approach In this research, a cross-sectional (...) study of commercial lighting industry domain in Australia was carried out, focusing on two states: New South Wales and Victoria. Based on the findings, an approach and a supporting platform to enhance competitiveness of commercial lighting industry were synthesized. Findings Based on the findings from the study, formation of such value chains, namely, “Entrusted Circles” and its two types of formations, fully and partial, were observed. Their further growth was hindered by high transaction costs. To reduce this transaction cost, this paper proposes a platform to create dynamic value chains, among stakeholders of commercial lighting industry, making use of growing digital connectivity leading toward agile formation of Entrusted Circles to enhance competitiveness. Research limitations/implications This study focuses on the commercial lighting industry in Australia, which is not tested in any other domain to investigate its wider applicability. However, it is conceptually applicable to be used in industries with compliance and standard procedures. Originality/value This paper shows how to identify Entrusted Circles and build, support and sustain such relationships among value chain partners to successfully conduct business transactions in a dynamic value chain.

Cyanolichens are symbiotic organisms involving cyanobacteria and fungi (bipartite) or with the addition of an algal partner (tripartite). Cyanolichens are known for their heightened susceptibility to environmental pollution. We focus here on the impacts on cyanolichens due to rising air pollution; we are especially interested in the role of sulfur dioxide on cyanolichen biology. Cyanolichens due to air pollution including sulfur dioxide exposure, show symptomatic changes including degradation of chlorophyll, lipid membrane peroxidation, decrease in ATP production, changes in respiration rate, (...) and alteration of endogenous auxins and ethylene production, although symptoms are known to vary with species and genotype. Sulfur dioxide has been shown to be damaging to photosynthesis but is relatively benign on nitrogen fixation which proposes as a hypothesis that the algal partner may be more in harm’s way than the cyanobiont. In fact, the Nostoc cyanobiont of sulfur dioxide-susceptible Lobaria pulmonaria carries a magnified set of sulfur (alkane sulfonate) metabolism genes capable of alkane sulfonate transport and assimilation, which were only unraveled by genome sequencing, a technology unavailable in the 1950–2000 epoch, where most physiology- based studies were performed. There is worldwide a growing corpus of evidence that sulfur has an important role to play in biological symbioses including rhizobia-legumes, mycorrhizae-roots and cyanobacteria-host plants. Furthermore, the fungal and algal partners of L. pulmonaria appear not to have the sulfonate transporter genes again providing the roles of ambient-sulfur (alkanesulfonate metabolism etc.) mediated functions primarily to the cyanobacterial partner. In conclusion, we have addressed here the role of the atmospheric pollutant sulfur dioxide to tripartite cyanolichen viability and suggest that the weaker link is likely to be the photosynthetic algal (chlorophyte) partner and not the nitrogen-fixing cyanobiont.
