AbstractThere is scarce evidence in review of the available literature to support a clear and superior model for the transition of care for epilepsy patients from pediatric to adult centers. Anecdotally, there is a common perception that families are reluctant to make this change and that the successful transition of care for epilepsy can be a challenge for patients, families, and physicians. As part of the effort to prepare the patient and family for the adult model of care, several treatment issues should be addressed. In this article, we discuss the specific challenges for physicians in transition of care for epilepsy patients from a pharmacological standpoint, which include differences in metabolism and pharmacodynamics that can impact tolerability or efficacy of antiepileptic medications, lifestyle changes affecting medication compliance and seizure control, acquired adult health conditions necessitating new medications that may result in adverse drug interactions, and adult neurologists' potential lack of familiarity with certain medications typically used in the pediatric epilepsy population. We offer this as a guide to avoid one of the many possible pitfalls when epilepsy patients transition to adult care.

We examined the influence of locus of control on the relationship between social exclusion and preference for distinctive choices. Participants were 212 undergraduate students at a university in Central China, who completed measures of social exclusion, locus of control, choice, and perceived uniqueness. Results showed that participants who believed that the environment controlled their fate (external locus of control) preferred more distinctive choices in a social exclusion context than in a social inclusion context, whereas participants who believed that they could control the environment (internal locus of control) preferred less distinctive choices. Further, perceived uniqueness mediated the effect of social exclusion and locus of control on choice. These results add to the literature on social exclusion and personal control.

AbstractWe introduce and study a new kind of nonlocal boundary value problems of multi-term fractional differential equations. The existence and uniqueness results for the given problem are obtained by applying standard fixed point theorems. We also construct some examples for demonstrating the application of the main results.

In this paper, we give existence and uniqueness results for backward stochastic differential equations when the generator has a polynomial growth in the state variable. We deal with the case of a fixed terminal time, as well as the case of random terminal time. The need for this type of extension of the classical existence and uniqueness results comes from the desire to provide a probabilistic representation of the solutions of semilinear partial differential equations in the spirit of a nonlinear Feynman-Kac formula. Indeed, in many applications of interest, the nonlinearity is polynomial, e.g, the Allen-Cahn equation or the standard nonlinear heat and Schrödinger equations.

AbstractIn this paper, we introduce a two-point boundary value problem for a finite fractional difference equation with a perturbation term. By applying spectral theory, an associated Green’s function is constructed as a series of functions and some of its properties are obtained. Under suitable conditions on the nonlinear part of the equation, some existence and uniqueness results are deduced.
