Solution-focused Brief Therapy (SFBT) has generated outcome research worldwide and in a variety of intervention contexts. A systematic literature search yielded 251 published studies on SFBT. SFBT was found superior to control groups or at post-test almost nine out every ten studies. Taking only 91 randomized controlled trials (RCTs) into account, still seven ten. Results varied slightly accord...

The purpose of this paper is to prove the global existence solution for one most significant fractional partial differential system called reaction-diffusion system. This will be carried out by combining compact semigroup methods with some L1-estimate methods. Our investigation can applied a wide class equations even if they contain nonlinear terms in their constructions.

Let $${\mathcal {L}}=\sum _{j=1}^{m}X_{j}^{2}$$ be a Hörmander sum of squares vector fields in $${\mathbb {R}}^{n}$$ , where any $$X_{j}$$ is homogeneous degree 1 with respect to family non-isotropic dilations . Then, {L}}$$ known admit global fundamental solution $$\Gamma (x;y)$$ that can represented as the integral sublaplacian operator on lifting space {R}}^{n}\times {\mathbb {R}}^{p}$$ equi...
