Background: An association between gaming disorder and the symptoms of common mental disorders is unraveled yet. In this preregistered study, we quantitatively synthesized reliability, convergent and discriminant validity of GD scales to examine association between GD and other constructs.Methods: Five representative GD instruments were chosen based on recommendations by the previous systematic review study to conduct correlation meta-analyses and reliability generalization. A systematic literature search was conducted through Pubmed, Proquest, Embase, and Google Scholar to identify studies that reported information on (...) either reliability or correlation with related variables. 2,124 studies were full-text assessed as of October 2020, and 184 were quantitatively synthesized. Conventional Hedges two-level meta-analytic method was utilized.Results: The result of reliability generalization reported a mean coefficient alpha of 0.86 and a mean test-retest estimate of 0.86. Estimated effect sizes of correlation between GD and the variables were as follows: 0.33 with depression, 0.29 with anxiety, 0.30 with aggression, –0.22 with quality of life, 0.29 with loneliness, 0.56 with internet addiction, and 0.40 with game playtime, respectively. The result of moderator analyses, funnel and forest plots, and publication bias analyses were also presented.Discussion and Conclusion: All five GD instruments have good internal consistency and test-retest reliability. Relatively few studies reported the test-retest reliability. The result of correlation meta-analysis revealed that GD scores were only moderately associated with game playtime. Common psychological problems such as depression and anxiety were found to have a slightly smaller association with GD than the gaming behavior. GD scores were strongly correlated with internet addiction. Further studies should adopt a rigorous methodological procedure to unravel the bidirectional relationship between GD and other psychopathologies.Limitations: The current study did not include gray literature. The representativeness of the five tools included in the current study could be questioned. High heterogeneity is another limitation of the study.Systematic Review Registration: [https://www.crd.york.ac.uk/PROSPERO/], identifier [CRD42020219781]. (shrink)

This study compares and analyzes separate court rulings in three countries on “mini-cup jelly” (a firm jelly containing konjac and packaged in bite-sized plastic cups) from a food ethics perspective. While the Korean and US courts decided that the mini-cup jelly was defective, and that the manufacturers or importers were liable for damages in these cases, the Japanese court took an opposing stance in favor of the manufacturer. However, from an absolute and fundamental viewpoint, the jelly was unacceptable, ethically as (...) well as legally, because it was unsafe, unwholesome, and unfit for children’s consumption. I argue that the ignoring or sidelining of fundamental principles of food ethics, especially “respect for life,” was at the core of these cases. If the manufacturers and importers had considered and prioritized the principles of food ethics over and above big sales and profits, the choking accidents could have been prevented. To conclude, it is very important to minimize risks by applying the principles of food ethics at the outset before any accidents can occur. (shrink)

It has long been believed across languages that the Agent‐First strategy, a comprehension heuristic that maps the first noun onto the agent role, is a general cognitive bias which applies automatically and faithfully to children's comprehension. The present study asks how this strategy interplays with such grammatical cues as the number of overt arguments and the presence of case‐marking in Korean, an SOV language with case‐marking by dedicated markers. To investigate whether and how these cues affect the operation of this (...) strategy, we measure children's comprehension of a transitive construction (with scrambling and omission of sentential components) in a novel experimental setting where arguments and case markers were obscured to varying degrees through acoustic masking. We find that children do not demonstrate the agent‐first interpretation strongly in the noun–verb pattern without case‐marking, showing their uncertainty about the thematic role of the nominal when it is both the only argument in the sentence and lacks case‐marking. They perform significantly better in the patterns with additional cues, the impact of which is asymmetric by age and by the nature of alignment between cues from word order and case‐marking. These findings suggest that, for Korean‐speaking children's comprehension of a transitive construction, the Agent‐First strategy is activated properly only in conjunction with other types of interpretive cues.

Although companies recognize the importance of social responsibility and community engagement, conflicts between companies and communities have been noticeably increasing. To better understand the role of institutional environments in company–community conflicts, we analyze two mining conflicts—Minera Yanacocha's Minas Conga extension project in Peru and Minera Los Pelambres' El Mauro Tailings Dam in Chile. Our findings imply that, to prevent negative consequences and alleviate company–community conflicts, mining companies should address underlying structural causes and pursue informal approaches in order to obtain and (...) maintain their social license. We find that better formal institutional environments not only alleviate conflict intensity but also facilitate informal approaches through which companies and communities can cooperate to resolve conflicts. The best practice would be to start and continue dialogs between communities and companies, mediated by impartial governments, to understand the concerns of the counterparty and find means by which to address the causes.
