An existence result for a Neumann problem
2015
The main result of this paper deals with the existence of at least one positive solution for a second order Neumann boundary value problem. Such a result is obtained by using an abstract coincidence point theorem that allows to get our conclusion under non standard conditions on the nonlinearity.
Bifurcation phenomena for the positive solutions of semilinear elliptic problems with mixed boundary conditions
2016
We consider a parametric semilinear elliptic equation with a Cara-theodory reaction which exhibits competing nonlinearities. It is "concave" (sub-linear) near the origin and "convex" (superlinear) or linear near $+\infty$. Using variational methods based on the critical point theory, coupled with suitable truncation and comparison techniques, we prove a bifurcation-type theorem, describing the set of positive solutions as the parameter varies.
Positive clinical psychology and positive technologies
2017
La Psicología Clínica ha avanzado notablemente en los últimos 100 años y en estos momentos disponemos ya de tratamientos psicológicos basados en la evidencia. Ahora bien, esto no es óbice para seguir mejorando esta disciplina. En los últimos 20 años se han producido dos importantes desarrollos que han resultado beneficiosos para este campo. Por una parte, lo que ha supuesto el movimiento de la Psicología Positiva y su cristalización en la Psicología Clínica Positiva. Por otra, la introducción de las Tecnologías de la Información y la Comunicación (TICs) para mejorar la práctica clínica cotidiana. En este trabajo se abordan estos avances y se presenta un nuevo campo de estudio que intenta es…
PPOSITIVE CLINICAL PSYCHOLOGY AND POSITIVE TECHNOLOGIES
2017
Clinical psychology has advanced significantly in the past hundred years, and we now have evidence-based psychological treatments. However, this does not mean that there is no room for further improvement in this discipline. In the past twenty years, two important developments have been identified as being beneficial for this field: on the one hand, the Positive psychology movement and its crystallization in the discipline of positive clinical psychology; on the other, the introduction of information and communication technologies (ICTs) to improve daily clinical practice. In this paper, we address these developments and present a new field of study that attempts to strengthen the ties and …
Distribution of ventilation and oxygenation in surgical obese patients ventilated with high versus low positive end-expiratory pressure: A substudy o…
2022
BACKGROUND Intra-operative ventilation using low/physiological tidal volume and positive end-expiratory pressure (PEEP) with periodic alveolar recruitment manoeuvres (ARMs) is recommended in obese surgery patients.OBJECTIVES To investigate the effects of PEEP levels and ARMs on ventilation distribution, oxygenation, haemodynamic parameters and cerebral oximetry.DESIGN A substudy of a randomised controlled trial.SETTING Tertiary medical centre in Geneva, Switzerland, between 2015 and 2018.PATIENTS One hundred and sixty-two patients with a BMI at least 35 kg per square metre undergoing elective open or laparoscopic surgery lasting at least 120 min.INTERVENTION Patients were randomised to PEEP…
Protective ventilation with high versus low positive end-expiratory pressure during one-lung ventilation for thoracic surgery (PROTHOR): study protoc…
2018
Postoperative pulmonary complications (PPC) may result in longer duration of in-hospital stay and even mortality. Both thoracic surgery and intraoperative mechanical ventilation settings add considerably to the risk of PPC. It is unclear if one-lung ventilation (OLV) for thoracic surgery with a strategy of intraoperative high positive end-expiratory pressure (PEEP) and recruitment maneuvers (RM) reduces PPC, compared to low PEEP without RM.PROTHOR is an international, multicenter, randomized, controlled, assessor-blinded, two-arm trial initiated by investigators of the PROtective VEntilation NETwork. In total, 2378 patients will be randomly assigned to one of two different intraoperative me…
Regularization of perturbed state-dependent sweeping processes with nonregular sets
2018
International audience; In this paper, we prove the convergence strongly pointwisely (up to a subsequence) of Moreau-Yosida regularization of perturbed state-dependent sweeping process with nonregular (subsmooth and positively alpha-far) sets in separable Hilbert spaces. Some relevant consequences are indicated.
The Lineup of Social Entrepreneurship
2021
As an introductory chapter to the second section, this chapter describes the sequence of the social entrepreneurship analysis followed from the macro perspective. As a chronology, the construction of social ventures begins with a social problem or an unjust social equilibrium. At this point, an individual tries to change the unjust situation through a disruptive idea. The big challenge for that individual arises because, as in any equilibrium situation, institutional forces make difficult the shift from one situation to another. One of the main issues linked to the institutional forces is legitimacy, which can be seen to a certain extent as conflicts of interest. Finally, social ventures an…
Pot ser positiu, l'estrès? Recerca de la proporció òptima entre la percepció positiva i negativa de l'estrès
2010
L'objectiu d'aquest treball és reflexionar sobre el nou rumb que s'ha iniciat en la investigació sobre l'estrès laboral. S'hi posa de manifest l'existència d'una proporció de «positivitat» en la percepció de l'estrès que pot afectar la «florida», la síndrome d'esgotament professional i la implicació en el treball. En aquesta relació, la cultura hi pot tenir un paper fonamental.
The Regulatory State vs. the Networked Polity: confronting narratives of change
2014
The aim of the article is to summarize and reassess the innovations brought about by governance theory. It is argued that the notion of governance is a conceptual device that could help rationalise and articulate the changes undertaken by liberal democracies since the late 1970s. The article suggests the need to distinguish between two distinct research programmes composing governance studies, which are influenced by alternative epistemic traditions—political economy and economic sociology. Rationalizations of change influenced by political economy support the idea that the outcome of recent political change is a market-oriented “Regulatory State”, while those influence by economic sociolog…
