AbstractThis study investigates how engagement (E), foreign language enjoyment (FLE), and ambiguity tolerance (AT) exert mediation/moderation in metaverse-based foreign language learning (FLL). Featuring augment/simulation-based experiences and self-fulfillment/external-control-oriented mechanics, metaverse provides virtualized interactive circumstances involving individuals' embodied presence/behaviors, aligning with FLL that emphasizes social interaction. Based on the quantified survey data, partial least squares structural equation modeling (PLS-SEM) analyses investigate the significance and positivity of the mediation/moderation relations. According to the results, E exerts fully positive mediation in the effect of intrinsic motivation (IM) on learning effectiveness (LE), FLE exerts partially positive mediation in the effect of classroom social climate (CSC) on E, and AT exerts negative moderation in the positive effect of E on LE. Notably, FLE exerts insignificant mediation in the effect of growth mindset (GM) on E. Therefore, efficient metaverse-based FLL requires synergies of affective factors, i.e., intrinsic motivation, perceptions of classroom social climate, moderate degrees of ambiguity tolerance, and engagement, for sustainable and long-term language learning progress in virtual interactive experiences. At the theoretical level, the findings extend the FLL-related models and advance the understanding of FLL. At the practical level, the findings provide references for more efficient metaverse implementations in FLL.

While many scholars find that security cooperation increases the foreign aid that allies receive from a major power, other studies show that an alliance also has negative effect and its terms can change over time. This article argues that a donor's security environment impacts its participation in security cooperation and, subsequently, foreign aid allocation to allies. When the security environment is competitive, a donor will concentrate its resources on strengthening its ties with allies. In contrast, when the environment is favorable to a donor, it can use security cooperation as leverage to obtain policy concessions from allies, thus reducing its own foreign aid expenditures. This paper analyzes the aid allocation of three major power donors as well as 72 formal defense pacts and 70 bilateral defense cooperation agreements, and it finds that a favorable security environment allows a donor to reduce its economic contribution to its allies by 19 percent.

Sexually Transmitted Diseases (STDs) were virtually eliminated in China in 1964 after Chinese government illegalized commercial sex and implemented active prevention and treatment programs among former sex workers (Chen et al., 2000). However, in the last three decades, the centralized economy in China made a transition to a more market-oriented economy, which brought significant changes in culture and social norms and dramatically influenced sexual attitude and behaviors among Chinese adults. One consequence of those changes is the significantly increasing prevalence of STDs in China(Abrams, 2001). The common STDs in China include gonorrhea, syphilis, AIDS, cervicitis, genital herpes, chancroid, lymphogranuloma venereum, and chlamydial infection.
