Sufficient Conditions for Conservativity of Minimal Quantum Dynamical Semigroups

The conservativity of a minimal quantum dynamical semigroup is proved whenever there exists a ``reference'' subharmonic operator bounded from below by the dissipative part of the infinitesimal generator. We discuss applications of this criteria in mathematical physics and quantum probability.Comment: 22 pages, Te

Differences in Corporate Social Responsibility Sensitivity Between Business and STEM Students

Purpose: The prominence of Corporate Social Responsibility (CSR) within the international business environment has permeated higher education wherein it has been incorporated alongside the study of business ethics in curricula across many majors. This study is unique in the literature of CSR education in that it  sought to determine if CSR sensitivity differed between undergraduate business majors and undergraduates majoring in the fields of science, technology, engineering, and mathematics (STEM). Research Design: A Mexican university was analyzed using demographic and attitudinal variables in a self-administered survey. The results indicated that students with STEM majors showed a higher CSR sensitivity than business majors – a unique finding in CSR literature. Findings: In general, female students had a higher sensitivity to CSR than male students. Students, regardless of their major, with little or no work experience expressed a higher sensitivity to CSR. Finally, year of study was significant in that seniors expressed a higher sensitivity than freshmen.&nbsp

The system of technical and specialized defense of the members of the public force

La Ley 1698 de 2013, creo el Sistema de Defensa Técnica y Especializada de los Miembros de la Fuerza Pública y en su artículo 16, faculta a los Militares abogados en servicio activo para que ejerzan una defensa litigiosa en procesos contencioso administrativos donde se encuentran vinculadas las Fuerzas Militares en la legitimación por pasiva, es por esta razón, que se busca analizar los antecedentes históricos y normativos, así como las características y elementos, del Sistema de Defensa Técnica y Especializada de los miembros de la Fuerza Pública creado por la Ley 1698 de 2013, no sin antes enunciar los antecedentes para la creación del FONDETEC, analizar los pronunciamientos de la Corte Constitucional en la C-127 de 2011 frente a la garantía de una defensa técnica y especializada, en la C-044 de 2015 y en la C-745 de 2015 donde se declaró exequible la Ley 1698 de 2013, siendo de vital importancia enunciar los antecedentes normativos para el ejercicio de la abogacía por parte de militares.The Law 1698 of 2013, I believe the System of Technical and Specialized Defense of the Members of the Public Force and in his article 16, it authorizes the Military men pleaded in active service in order that administrative officers exercise a litigious defense in processes contentious where the Military Forces are linked in the legitimization for passive, is for this reason that across the normative and juriprudential analysis seeks to define the scope of the efficiency and validity of the exercise of the judicial representation, not before to enunciate the precedents for the creation of the FONDETEC, To analyze the pronouncements of the Constitutional Court in the C-127 of 2011 opposite to the guarantee of a technical and specialized defense and in the C-044 of 2015 where one declared exequible the article 16 of the Law 1698 of 2013, performing vital importance to enunciate the normative precedents for the exercise of the law on the part of military men

Assent informed like exempting of medical contractual re-sponsibility

El cambio de cultura jurídica en la relación médico-paciente, evidenciado en la afirmación del principio de autonomía de la persona, supuso dejar al margen una relación con sentido paternalista y regida por el principio de beneficencia, para alcanzar una nueva situación, acorde con los tiempos, en la que el paciente y sus derechos se configuran como los protagonistas, es por eso, que surge la necesi-dad de establecer si existe o no responsabilidad contractual del galeno cuando se suscribe un consentimiento médico informado.The change of juridical culture in the relation doctor - patient demonstrated in the affirmation of the beginning of autonomy of the person, supposed leaving to the margin a relation characterized by a sense paternalistic and been ruled by the be-ginning of welfare, to reach a new situation, according to time, in that the patient and his rights are formed as the protagonists, it is because of it, that arises the need to establish if it exists or not contractual responsibility of the physician when one signs a medical informed assent

Long term nonlinear propagation of uncertainties in perturbed geocentric dynamics using automatic domain splitting

Current approaches to uncertainty propagation in astrodynamics mainly refer tolinearized models or Monte Carlo simulations. Naive linear methods fail in nonlinear dynamics, whereas Monte Carlo simulations tend to be computationallyintensive. Differential algebra has already proven to be an efficient compromiseby replacing thousands of pointwise integrations of Monte Carlo runs with thefast evaluation of the arbitrary order Taylor expansion of the flow of the dynamics. However, the current implementation of the DA-based high-order uncertainty propagator fails in highly nonlinear dynamics or long term propagation. We solve this issue by introducing automatic domain splitting. During propagation, the polynomial of the current state is split in two polynomials when its accuracy reaches a given threshold. The resulting polynomials accurately track uncertainties, even in highly nonlinear dynamics and long term propagations. Furthermore, valuable additional information about the dynamical system is available from the pattern in which those automatic splits occur. From this pattern it is immediately visible where the system behaves chaotically and where its evolution is smooth. Furthermore, it is possible to deduce the behavior of the system for each region, yielding further insight into the dynamics. In this work, the method is applied to the analysis of an end-of-life disposal trajectory of the INTEGRAL spacecraft
