Sin ti no soy nada. Participación de usuarios en Salud Mental

La participación de los usuarios es un derecho compartido con todos los ciudadanos y ciudadanas. En estos tiempos en los que la distancia entre los grupos que ostentan el poder de decisión el poder de decisión y la población es tan grande, podemos comprender mejor qué significa ser privado de este derecho por padecer una enfermedad mental

Cultivating a Community of Practice Among Student Teachers and Cooperating Teachers

This study examined the experience of four student teachers and their supervising teachers who participated in a Community of Practice (CoP) during their internship semester. Their experience can be separated into the four key components of a Community of Practice: (a) structure, (b) processes, (c) content, and (d) conditions

Growth of Sobolev norms in the cubic defocusing nonlinear Schrödinger equation

We consider the cubic defocusing nonlinear Schrödinger equation in the two dimensional torus. Fix s>1. Recently Colliander, Keel, Staffilani, Tao and Takaoka proved the existence of solutions with s -Sobolev norm growing in time. We establish the existence of solutions with polynomial time estimates. More exactly, there is c>0 such that for any K»1 we find a solution u and a time T such that ¿u(T)¿Hs=K¿u(0)¿Hs. Moreover, the time T satisfies the polynomial bound 0Peer ReviewedPostprint (author's final draft

On the Role of Ferromagnetic Interactions in Highly Active Mo-Based Catalysts for Ammonia Synthesis

Reactions involving nitrogen fixation and transfer are of great industrial interest. In this regard, unveiling all the physical principles that determine their activity would be enormously beneficial for the rational design of novel catalysts with improved performance. Within this context, this work explores the activity of bulk molybdenum-based transition metal nitrides in ammonia synthesis. Our results highlight that the most active compositions show increasing ferromagnetism in the metal–nitrogen bonds, which constitute the active sites. We observe that the total spin accumulated in the bonds at the active sites is a physically meaningful descriptor to discriminate optimum catalysts. Higher activities are associated with ferromagnetic phases, and the underlying reason is an enhanced overlapping of the electronic wavefunctions; which also make the reaction steps spin-sensitive. These finding provides strong evidence of the general influence of electrons magnetic moment in catalysis, being part of the specific field of spintro-catalysis

Visual Quality, Motility Behavior, and Retinal Changes Associated with Reading Tasks Performed on Electronic Devices

Background: The purpose of this study was to objectively evaluate visual discomfort using an eye tracker and aberrometer after a 21-min reading session on an iPad and an Ebook. Additionally, retinal changes were analyzed using optical coherence tomography (OCT). Methods: A total of 31 young subjects (24 ± 4 years) participated in this study. They read for 21 min on an Ebook and for another 21 min on an iPad under controlled lighting conditions while their eye movements were monitored using an eye tracker. Aberrometry and retinal OCT measurements were taken before and after each reading session. Parameters such as pupil diameter, fixations, saccades, blinks, total aberration, high-order aberration, low-order aberration, and central and peripheral retinal thickness in the nine early treatment diabetic retinopathy study (ETDRS) areas were measured for each reading situation. Statistical analysis was performed on the collected data. Results: No statistically significant differences (p > 0.05) between the two devices were observed in terms of the different types of eye movements or the changes in retinal thickness. However, the aberrometric analysis showed variations in post-reading situations depending on the device used. Conclusion: Reading speed and visual discomfort resulting from electronic device usage can be objectively assessed using an eye tracker and aberrometer. Additionally, changes found in central and peripheral retinal thickness between the two devices and the baseline measurements were not significant and remained relatively stable

Penile Microvascular Arterial Bypass Surgery: Indications, Outcomes, and Complications

Penile microarterial bypass surgery (MABS) may be the only treatment capable of restoring normal erectile function without the necessity for the chronic use of vasoactive medications or placement of a penile prosthesis. Lack of standardization in patient selection, hemodynamic evaluation, surgical technique, and limited long-term outcome data using validated instruments has resulted in this surgery being considered experimental. The members of the Erectile Dysfunction Guideline Update Panel reviewed the available MABS publications and only four of 31 manuscripts met the criteria for the Arterial Occlusive Disease Index patient. The total studied population of these four publications was 50, which was considered too small to determine if MABS is effective or not. Reported successful outcomes were 36-80 and 91% for inferior epigastric artery (IEA) to dorsal vein and IEA to dorsal artery MABS, respectively. We recently published the largest long-term outcome MABS study using validated questionnaires (71 men aged 30.5 ± 9.2 years; mean follow-up 34.5 ± 18 months). The mean pre- and postoperative total International Index of Erectile Function, erectile function domain, questions 3 and 4 scores were 35.5 ± 14.8, 13.7 ± 6.7, 2.2 ± 1.4, 2.1 ± 1.3, and 56.2 ± 16.6, 23.8 ± 6.6, 4.1 ± 1.4, and 3.9 ± 1.5, respectively. In addition, 55 and 73% of patients reported erectile function domain scores ≥26 and 21, respectively, and almost 90% of patients would recommend or undergo MABS again. In addition, changes in pre- and postoperative sexual distress scale scores and the Center for Epidemiologic Studies Depression Scale were statistically significant. More importantly, treatment satisfaction (EDITS) was very high, and 87% of patients would recommend the surgery to someone else and 88.7% reported a significant improvement in their erectile function. In patients with no vascular risk factors and pure cavernosal arterial insufficiency, MABS provides long-term improvements in erectile function, depression, and overall satisfaction

Breakdown of homoclinic orbits to L3 in the RPC3BP (II). An asymptotic formula

PreprintThe Restricted 3-Body Problem models the motion of a body of negligible mass under the gravitational influence of two massive bodies called the primaries. If one assumes that the primaries perform circular motions and that all three bodies are coplanar, one has the Restricted Planar Circular 3-Body Problem (RPC3BP). In rotating coordinates, it can be modeled by a two degrees of freedom Hamiltonian, which has five critical points called the Lagrange points L1,.., L5. The Lagrange point L3 is a saddle-center critical point which is collinear with the primaries and beyond the largest of the two. In this paper, we obtain an asymptotic formula for the distance between the stable and unstable manifolds of L3 for small values of the mass ratio 0<µ«1. In particular we show that L3 cannot have (one round) homoclinic orbits. If the ratio between the masses of the primaries µ is small, the hyperbolic eigenvalues of L3 are weaker, by a factor of order µ--v, than the elliptic ones. This rapidly rotating dynamics makes the distance between manifolds exponentially small with respect to µ--v. Thus, classical perturbative methods (i.e the Melnikov-Poincaré method) can not be applied. The obtention of this asymptotic formula relies on the results obtained in the prequel paper on the complex singularities of the homoclinic of a certain averaged equation and on the associated inner equation. In this second paper, we relate the solutions of the inner equation to the analytic continuation of the parameterizations of the invariant manifolds of L3 via complex matching techniques. We complete the proof of the asymptotic formula for their distance showing that its dominant term is the one given by the analysis of the inner equation.Preprin
