    The Policy Making on Venezuelan Migratory Policies in Peru 2017-2022: Processes, Bifurcation Points and Drivers
    (Universidad Pontificia Comillas de Madrid, 2026-01-01)
    This study examines Peruvian public policies on Venezuelan migration, identifying factors influencing their formulation and implementation while uncovering their behavioral patterns. Using a qualitative approach based on process tracing and thematic analysis of official documents, media narratives, and statistical data, the research identifies three phases of migration policy: (1) open-door policies, (2) securitization and restriction, and (3) invisibilization and normalization of irregular migration. These phases reveal a disconnect between political rhetoric and practical outcomes, with calculated tolerance for policy non-enforcement and migrant integration delegated to civil society and international organizations. The findings highlight incoherent migration policies marked by legal non-compliance, omission as a strategy, and limited state intervention. These dynamics are driven by advocacy coalitions excluded from decision-making, strained executive-legislative relations, and media-influenced public opinion. The study's originality lies in its innovative combination of process tracing and thematic analysis to explain policy dynamics in contexts of institutional fragility.

    Soliton dynamics under the influence of an external force and induced-damped terms within the modified Korteweg-de Vries equation
    (Springer Science+Business Media, 2026-01-01)
    The interaction of a solitary wave with an external force is studied within the framework of a modified Korteweg-de Vries equation, accounting for viscosity and damping. Using asymptotic methods, a dynamical system is derived to describe the amplitude and phase of the solitary wave. A bifurcation analysis of this system is presented, depending on the parameters characterizing viscosity and flow, and the conditions for the trapping of the solitary wave by the external force are examined. The obtained asymptotic results are compared with direct numerical simulations. The asymptotic and numerical results agree for all types of equilibrium points in the dynamical system.
