    “…The expectation is to identify risk factors for PTB having a greater predictive power than classically studied factors. The final objective is to propose more effective interventions for the reduction of PTB, which, after being tested, might subsidize health policies. …”

    “…The colonization by different beetle species is dependent on host status, from healthy trees to the early stages of wood decay, although the precise factors influencing their host selection are not well known. Classic studies on plant ecology have determined the niches of different plant species in vegetation succession, based on comparisons of successions in different locations using ordination analyses, although the factors influencing the colonization of each species are largely undetermined. …”

    “…Epistemológicamente, se apuesta por abordajes procesuales; teóricamente, por un uso de las definiciones conceptuales menos preocupado por identificar los límites entre los distintos tipos de retorno y más interesado en comprender la mutación de unos a otros; metodológicamente, por diseños y técnicas que estudien los retornos en términos retrospectivos y proyectivos; empíricamente, por la estrategia del “anclaje” como herramienta útil para hacer operativas investigaciones que, sin confundir rigurosidad con rigidez, den cuenta de la riqueza y complejidad de los procesos contemporáneos de retorno.Palabras clave: Retornos y procesos migratorios, Espacialidades-temporalidades múltiples, Trayectorias migratorias y curso de vida Challenges in the Study of Return MigrationSummaryThe theoretical and methodological challenges of defining return migration as an object of study are not new in the social sciences.  Even in classic studies, we detect difficulties that contemporaries sought to overcome; an example of them being the research from a transnational perspective whose procedural approach considers the return as a phase in the migratory trajectories, which supposes an open ended process.  …”
