Nonresonance For Problems Involving (P, Q)-Laplacian Equations With Nonlinear Perturbations, E. Lopera, Nsoki Mavinga, D. Sánchez

Mathematics & Statistics Faculty Works

We are concerned with the existence of solutions of (p, q)-Laplacian problems that include nonlinear perturbation terms in both the differential equations and the boundary. Using variational methods and critical point theory, we prove the existence of weak solutions for the nonlinear problem when the nonlinearities involved remain asymptotically below the infimum of the set of eigenvalues of the (p, q)-Laplacian problem with weights and a spectral parameter present in both the differential equation and the boundary. Additionally, we establish an existence result for the nonlinear problem when the nonlinearities involved remain asymptotically below …

Reducing Youth False Confessions With Attorney Presence, Rosa Bowden-Maccalla

Walden Dissertations and Doctoral Studies

Interrogation techniques are influenced by the interrogator's style and the individual being interviewed. Most law enforcement agencies use adult-centered interrogation methods, leading to suboptimal results when working with youth. The research has focused on youth offenders in the interrogation room and the choices they make, often leading to false confessions when an attorney is absent. This suggests that the presence of legal representation helps protect youths' vulnerability, suggestibility, and rights, thereby reducing the likelihood of false confessions. This qualitative collective case study aimed to understand why youth offenders falsely confess by collecting seven anonymous questionnaires from multigender U.S. practicing attorneys …
