3.2 Comparative Synthesis Criteria for Early-Career Trajectory Studies
To examine the structural mechanisms underlying researcher precarity and early departure from higher education, this study employs a comparative qualitative synthesis protocol designed to evaluate secondary empirical evidence across institutional settings. The methodological framework integrates systemic and experiential paradigms to trace how contractual insecurity translates into career attrition across differentiated academic landscapes. Drawing upon systemic conceptualizations of researcher development, the analytical protocol incorporates the Systems Theory Framework to account for institutional hierarchies, employment security, professional development, and competing workplace roles (crossref-10-1177-14749041251392120). This systemic lens enables the rigorous categorization of structural drivers across macro-policy environments and micro-level academic workplaces without obscuring individual agency. To capture the complex embodied frictions that govern career decisions, the synthesis criteria operationalize the conceptual framework of stickiness, which delineates how affective considerations, normative excellence discourses, and geographic mobility mandates intersect during academic trajectories (crossref-10-1007-s10734-020-00596-1). Methodologically, this perspective prevents the reduction of academic attrition to purely economic calculations by systematically coding for emotional strain, personal relationships, and institutional immobility. Furthermore, the synthesis incorporates multi-stage narrative trajectory models—spanning anticipatory career thought, organizational entry, primary workplace experiences, and ultimate sectoral transition—to structure the sequential thematic coding of departure accounts (crossref-10-70315-uloap-ullli-2024-0101002). By triangulating systemic workplace influences, affective stickiness, and sequential career phases, this methodological architecture provides a comprehensive qualitative protocol for evaluating how institutional precarity destabilizes scientific career sustainability in contemporary higher education.
