This week in interdisciplinary scholarship: a digest of ten new open-access studies spanning sustainability reporting, journalism, finance, education, and marketing.
📊 This week at a glance
🌍 African-led research
Accounting professionals in emerging economies often adopt sustainability reporting standards as symbolic compliance rather than genuine engagement.
Using self-determination theory (a framework explaining motivation through autonomy, competence, and relatedness), the study argues this gap stems from professionals’ unmet psychological needs. The implication is that training and policy must address intrinsic motivation, not just technical compliance. For African scholarship, it highlights why ISSB adoption may not translate into substantive sustainability action without deeper institutional support.
Community radio journalists in Limpopo, South Africa, negotiate safety, ethics, and community expectations while covering service delivery protests.
The study documents how these journalists operate on a precarious frontline, balancing professional duties with personal risk. It changes the assumption that community media are simply local mouthpieces, showing instead their active negotiation of complex pressures. This matters for African media policy and journalism training, which often overlook the specific challenges of community radio in protest coverage.
Business enterprise research and development (BERD) has a long-term association with environmental sustainability in Japan.
The study shifts focus from public-sector innovation to corporate R&D as a driver of macro-level sustainability outcomes, grounded in the Porter Hypothesis (which argues that strict environmental regulation can spur innovation). The implication is that private innovation channels matter for national sustainability performance. For African policymakers, it suggests that supporting corporate R&D could be a lever for environmental goals, though context-specific evidence is needed.
Medical students at Abubakar Tafawa Balewa University in Nigeria prefer practical demonstrations and digital learning tools over traditional lectures.
A survey of 171 students found that problem-based learning (PBL) and team-based learning (TBL) were also favored, indicating a shift away from passive instruction. This changes how medical educators might design curricula to improve engagement and outcomes. For African medical schools, it supports calls for more interactive, resource-appropriate teaching methods.
Search attention spikes predict volatility but not returns in Korea’s AI-related stocks.
Using daily Naver search and KRX data for 108 AI firms from 2020 to 2026, the study found that search shocks coincide with abnormal trading and price movements but do not reliably forecast next-day or 5-day returns. Instead, they forecast realized volatility. This matters for investors and regulators in emerging markets, showing that attention signals turbulence rather than direction.
Lecturers and administrators across six Rwandan universities identify challenges and innovation demands shaping 21st-century teaching.
The qualitative study developed a framework to enhance lecturer effectiveness, based on interviews and focus groups. It changes the conversation from generic teaching standards to context-specific innovations in Rwandan higher education. For African scholarship, it offers a locally grounded model for improving university teaching.
🔬 Global breakthroughs
ChatGPT can forecast stock price movements, according to a study on return predictability and large language models.
The paper, published in the Journal of Financial Economics, examines whether LLMs like ChatGPT can predict stock returns. As the abstract is empty, details are limited, but the title indicates a focus on return predictability. This matters for African financial markets as AI tools become more accessible for analysis.
Virtual influencers are more impactful when they appear in photos with humans, suggesting social tie presence drives engagement.
A multimethod investigation found that computer-generated influencers who seem to have social interactions with humans generate higher consumer engagement. This changes how brands might design virtual influencer campaigns, moving beyond pure aesthetics to simulated social connections. For African marketers, it offers a cost-effective strategy for reaching digital audiences.
The Shapley value for airport and irrigation games provides a new characterization of cost-sharing on rooted trees.
The study introduces a formal notion of irrigation games and shows that airport games are a subclass. It advances cooperative game theory by clarifying how costs can be fairly allocated in tree-structured problems. For African researchers in operations research, it offers a mathematical tool for infrastructure and resource-sharing challenges.
Ideal L2 self and control-value appraisals are linked to learner engagement in AI-supported informal digital English learning.
Using structural equation modeling and fuzzy-set qualitative comparative analysis on 653 Chinese university students, the study integrates L2 selves and control-value theory. It shows that emotional and motivational factors interact to shape engagement in AI-driven informal learning. For African language educators, it highlights the importance of psychological factors when adopting AI tools.
