Colors are not preset topics — Louvain community detection groups questions by how they link. V400 contains 401 questions (114 original + 260 expanded research gaps + 6 design questions + 21 GAP new questions) grouped into 19 clusters.
| Real Project Value & Data Constraints | How real project value is perceived and how data access/visibility constrain it |
| Institution Incentives, Compliance & Governance | Institution-side funding, compliance, reputation and governance motives |
| Time Scales, Mobilization & Attrition Attribution | Cohort/budget-year mismatches, mobilization, and whether churn is value or crowding-out |
| Reputation Risk, Value Creation & Churn Measurement | School/firm reputation risk, value creation, and measuring relationship churn |
| Teaching Capacity, Extra Costs & Grade Preferences | Instructor/TA workload, added costs, and grade-based selection effects |
| School Power, Access & Bargaining Asymmetry | School size/power, opportunity fairness, and bargaining asymmetry with firms |
| Governance & Stakeholder Salience | Governance arrangements and which stakeholder claims get attended to |
| Course Scaffolding & Grade-Level Projects | How courses are scaffolded and projects assigned across grade levels |
| Success Criteria, Accountability & Outcome Measurement | Whose success criteria win and how outcomes are attributed/measured |
| AI, Transaction Costs & Student Signals | AI screening, transaction costs, and student-side signaling |
| Value Realization Lag, Repetition & Course Distinctiveness | The 2-3 year lag, repeated offerings, and what makes a course distinctive |
| Firm Efficiency & Commitment Signals | Where firm-side efficiency loss concentrates and which long-term-intent signals are credible |
| TA Scalability & Continuity | TA resource allocation, scaling, and continuity across cohorts |
| Mechanism Design & Governance Theory | Five-party incentive design, value capture, and governance mechanisms |
| Multi-School Costs & Project Budgets | Costs across school teams, project budgets, and scale sensitivity |
| Firm Types & Incentive Heterogeneity | Firm type differences and heterogeneous participation incentives |
| Try-Before-You-Buy, Signaling & Screening | Firm try-before-buy, student pay-to-signal, and screening/selection |
| Attrition, Sustainability & Time Mismatch | Why participation decays, whether mobilization lowers it, and one-shot course return |
| Output Ownership & Portability | Who owns outputs and whether students/firms can carry them across courses |
A line is not "this question causes that one" (not causal), but "these two are two sides of the same thing". Composed of two signals:
Hover or click any node — the right panel lists "why linked (shared tags / citations)", which is the evidence for that line.
Clusters sit close together when they describe the same mechanism from different stakeholders — for example, attrition is the symptom, time mismatch the cause, and mechanism design the cure. This adjacency is a finding, not a rendering bug.
The highest-betweenness questions now sit on institution funding/reputation and firm value/sustainability, confirming that five-party incentive alignment and sustainability remain the research spine.
