Social entrepreneurship: Dimensions of opportunity tracing framework

The objective of this paper is to come up with a theoretical framework that would identify different factors that Social Entrepreneurs can use in their respective opportunity tracing processes, so that they can have a holistic view of looking at the opportunity in the context of introducing a change to an unjust equilibrium in a sustainable way. It examines how opportunity is seen through three dimensions, namely (1) the goal of the Social Entrepreneur, (2) the role of the Social Entrepreneur, and (3) business models that will sustain the social entrepreneurship processes. Further studies is needed to be able to add more dimensions on opportunity tracing process from the vast literature available about social entrepreneurship

Social entrepreneurship: An integrated approach for sustainable development

Social Entrepreneurship (SE) initiated changes on how to approach current global challenges to society\u27s most pressing social problems such as poverty, literacy, environmental and social ills, to name a few and provided innovative solutions that created sustainable development. This paper examined the concept of Social Entrepreneurship, and how social entrepreneurs identified opportunity that responded to these current global challenges. It presented a model for sustainable social value creation based on the social entrepreneurs\u27 values and continuous improvement principles to constantly validate the principles behind the value capture of opportunities

Planning Reliable Paths with Pose SLAM

The maps built by standard feature-based SLAM methods cannot be directly used to compute paths for navigation, unless enriched with obstacle or traversability information with the consequent increase in complexity. Here, we propose a method that directly uses the Pose SLAM graph of constraints to determine the path between two robot configurations with lowest accumulated pose uncertainty, i.e., the most reliable path to the goal. The method shows improved navigation results when compared to standard path planning strategies, both over datasets and real world experiments

Impacto de acciones de mejora en la prevención de infección urinaria nosocomial (IUN) en pacientes con sondaje vesical (1991-2010)

Aproximadamente el 19% (EPINE 2010) (1) de los pacientes ingresados en un centro sanitario está sometido de forma temporal a la cateterización de las vías urinarias (CV). En el caso de los pacientes ingresados en una unidad de cuidados intensivos esta cifra puede alcanzar el 71,10% (ENVIN-UCI 2010) (2). Aunque los efectos adversos asociados a este procedimiento son relativamente benignos, en ocasiones pueden derivar en complicaciones más graves con aumento de la morbilidad, de los costes asociados y que generan un importante disconfort para el paciente (3). En mayo de 1991, en el marco de nuestra participación en un estudio multicéntrico sobre uso de CV en los hospitales (4), detectamos que en nuestro centro el 9% de los pacientes ingresados era portador de CV y de ellos un 27,5% presentaba IUN (3). Aunque nuestros resultados no discrepaban de los obtenidos en el conjunto de hospitales, consideramos que estos valores ofrecían una clara oportunidad de mejora. Un dato relevante fue la evidencia de que en más de una cuarta parte de los pacientes el motivo de sondaje había sido la presencia de una incontinencia urinaria. Históricamente, el CV se introdujo en los hospitales para la asistencia de pacientes con patología obstructiva urológica y para el control hemodinámico en situaciones clínicas de gravedad, sin embargo debido al incremento de edad de los pacientes hospitalizados se encuentra una mayor prevalencia de casos de incontinencia urinaria. Ante esta disfunción, el personal asistencial opta frecuentemente por sondar al paciente. A partir de este estudio se implantaron programas de mejora mantenidos con el objetivo de reducir las tasas de infección urinaria nosocomial asociada al uso de CV y mejorar el cumplimiento de la indicación de CV, así como optimizar la calidad del cuidado del paciente sondado.Approximately 19% (EPINE 2010) (1) of the patients admitted to a health care center are submitted in a temporary way to the catheterization of the urinary ways (CV). In the case of the patients admitted to an intensive care unit this number can reach 71.10% (ENVIN-UCI 2010) (2). Although the adverse effects associated to this procedure are relatively benign, on occasions, they can derive, in more severe complications with increase of the morbidity, from the associated costs and that generate an important discomfort for the patient (3). In May 1991, within the framework of our participation in a multicentre study on use of CV in the hospitals (4), we detect that in our health care center 9% of new patients were wearing CV and of them 27.5% had IUN (3). Although our results did not disagree with the ones obtained in the set of hospitals, we consider that these values offered a clear opportunity of improvement. A relevant data was the evidence that in more than a fourth part of the patients the reason of sounding had been the presence of a urinary incontinence. In a historical way, CV was introduced at hospitals for the patients assistance with urological obstructive pathology and for the hemodynamic control in clinical situations of gravity, however due to the increase of age of the hospitalized patients it is found a greater prevalence of cases of urinary incontinence. In the face of this dysfunction the health care staff opts frequently to catheterize the patient. From this study a set of improvement programs were carried out with the objective of reducing the rates of nosocomial urinary infection associated to the use of CV and improving the achievement of CV indication, thus as optimizing the quality of the care of the catheterized patients
