Current Barriers to Large-scale Interoperability of Traceability Technology in the Seafood Sector.

Interoperability is a critical component of full-chain digital traceability, but is almost nonexistent in the seafood industry. Using both quantitative and qualitative methodology, this study explores the barriers impeding progress toward large-scale interoperability among digital traceability systems in the seafood sector from the perspectives of seafood companies, technology vendors, and supply chains as a whole. We highlight lessons from recent research and field work focused on implementing traceability across full supply chains and make some recommendations for next steps in terms of overcoming challenges and scaling current efforts.

The relation of economic status to subjective well-being in developing countries: a meta-analysis.

The current research synthesis integrates the findings of 111 independent samples from 54 economically developing countries that examined the relation between economic status and subjective well-being (SWB). The average economic status-SWB effect size was strongest among low-income developing economies (r = .28) and for samples that were least educated (r = .36). The relation was weakest among high-income developing economies (r = .10) and for highly educated samples (r = .13). Controlling for numerous covariates, the partial r effect size remained significant for the least-educated samples (pr = .18). Moderator analyses showed the economic status-SWB relation to be strongest when (a) economic status was defined as wealth (a stock variable), instead of as income (a flow variable), and (b) SWB was measured as life satisfaction (a cognitive assessment), instead of as happiness (an emotional assessment). Findings were replicated with a meta-analysis of the World Values Survey data. Discussion centers on the plausibility of need theory, alternative explanations of results, interpretation of moderators, and directions for future research.
