Manifesto for a better management a rational and humanistic view

At the end of the first decade of the 21st century, a disastrous world economic crisis is creating a very difficult situation for many people. The causes of the crisis are many and complex. The reigning economism looks for mechanical causes (excessively low interest rates, "herd" behavior in the real estate and financial bubbles, etc.). Yet bad management by the people in charge of many of the institutions affected has been crucial. Paradoxically, management can be responsible both for great successes and for great failures. The same term, "management", can refer to very different concepts. The emphasis on immediate effectiveness in terms of financial results (which always turn out to be short-term) as the sole purpose betrays a pessimistic conception of human beings as creatures that react only to economic stimuli, thus neglecting other dimensions that are fundamental to good management, and leading us to the present crisis. In this paper we aim to establish the starting points for good management, explain why management is important for society, critically analyze the present economic crisis and the practices and concepts that led to it, and propose the foundations of a better conception of management for the future, rejecting the culture of shortsightedness. We therefore set forth: a) Which concepts of the company and of management are conducive to management practices that are good for society as a whole. b) Why management is important for the development of human societies in general. c) What is good and what is bad about the practices and theories that currently dominate the world of management. d) How to prevent bad theory and bad practice, including bad applications of good theory, from influencing the broader trends.humanistic management; economism; reorienting management; Crisis;

Després de l'ESO, què? Eleccions i restriccions en els itineraris acadèmics i laborals de l'alumnat d'origen immigrat

Projecte de recerca subvencionat dins de la convocatòria ARAFI-2009 d'ajuts per incentivar la recerca aplicada en matèria d'immigració a Catalunya finançada per la Secretaria per a la Immigració i la Direcció General de Recerca de la Generalitat de Catalunya.Aquest article analitza, des d'una perspectiva biogràfica, la construcció dels itineraris acadèmics i laborals de joves d'origen sud-americà pertanyents a la generació 1,5 d'un institut públic de l'Hospitalet de Llobregat. Analitzarem específicament les transicions acadèmiques que es donen a l'acabament de l'ESO. A partir de la teoria de transicions del GRET, es reflexiona sobre aquestes trajectòries, la possibilitat d'una etnificació dels itineraris i alguns dels elements que els configuren: el procés migratori, la comprensivitat o la segregació del sistema educatiu, les expectatives i preferències acadèmiques i laborals, així com les diverses formes d'integració a la societat d'acollida.Este artículo analiza, desde una perspectiva biográfica, la construcción de los itinerarios académicos y laborables de jóvenes de origen sudamericano pertenecientes a la generación 1'5 de un instituto público del Hospitalet de Llobregat. Analizaremos específicamente las transiciones académicas y laborales que se dan al finalizar el ESO. A partir de la teoría de las transiciones del GRET reflexionamos sobre esas trayectorias, la posibilidad de una etnificación de los itinerarios y algunos de los elementos que los configuran: por ejemplo, el proceso migratorio, la comprensividad o segregación del sistema educativo, las expectativas y preferencias académicas y laborales, así como las diversas formas de integración en la sociedad de acogida.This article analyzes, from a biographical perspective, the construction of academic and occupational pathways of young people of South American origin, belonging to the 1.5 generation, in a state secondary school in L'Hospitalet de Llobregat. We study specifically transitions from the compulsory schooling to further education. Based on the theory of transitions of GRET, we reflect on these pathways, the possibility of a etnification of itineraries and some items that configure them: the migration process, the comprehensiveness or segregated educational system, academic and work expectations and preferences as well as different ways of integration into the host society.Cet article analyse la construction de parcours scolaires et professionnels des jeunes d'origine sud-américaine, qui appartiennent à la génération «1.5», dans un collège publique à Hospitalet de Llobregat. On analyse, dans une perspective biographique, les transitions scolaires qui se produisent à la fin de l'enseignement obligatoire (secondaire inferieure). Dans l'approche théorique des Transitions du GRET (Groupe de Recherche sur l'éducation et l'emploi) l'auteur réfléchit sur les itinéraires des jeunes, la possible «ethnification» de certains itinéraires et sur certains éléments qui les composent: le processus de migration, le niveau d'inclusion ou de ségrégation du système éducatif, les expectatives académiques des jeunes et leurs préférences scolaires ou de travail ainsi que plusieurs formes d'intégration dans la société d'accueil

¿Cómo abordar la dimensión colectiva de la salud de las personas? Informe SESPAS 2012

ResumenLa salud de los colectivos depende en gran parte de factores del entorno. Cabe plantearse cuál ha de ser el papel de los profesionales sanitarios, en especial de la salud pública y la atención primaria, en la formulación de objetivos y en el desarrollo de acciones para la mejora de la salud de la población. Se plantea un recorrido desde el conocimiento de las potencialidades y las necesidades de salud hasta las actividades que suponen una verdadera y positiva transformación, es decir, desde la información hasta la acción. Este recorrido transcurre a modo de conversacciones que sobre la salud cabe llevar a cabo. Se analiza la situación actual, sus debilidades y fortalezas, y se elaboran propuestas para todo el proceso: información, encuentro y acción. La información exige trascender los datos que las diferentes fuentes proporcionan, generando conocimiento a quienes pertenecen a la comunidad o están muy cerca de ella. Esta mirada debe contemplar, además de los déficits, los activos en salud, conocimiento útil para todos los que pueden influir en los determinantes de la salud, incluidos los sanitarios. Finalmente, al considerar las acciones para mejorar la salud, se insiste en los beneficios de la promoción de la salud en el sentido más genuino del término, mediante una reflexión en términos de efectividad y de eficiencia. El fracaso de una intervención que no consigue mejorar la salud, ¿se debe a su inutilidad o a que se desarrolla de manera inadecuada?AbstractThe health of the population largely depends on environmental factors, raising the issue of what the role of health professionals, particularly those in public health and primary care, should be in the planning of objectives and actions for improvement. The present article proposes a trajectory, starting with knowledge of the community's strong points in health and its needs, and ending with taking action. This trajectory requires discussion on how information can be transformed into action. We analyze the current situation and its strengths and weaknesses, and make proposals for the entire process: from information to action. Information is more than just the available data gathered from different sources; it is also knowledge of those who belong to the community or are very close to it. This perspective should include both health deficits and health assets. This information should be used not only by health professionals, but by all those in a position to influence the determinants of health. Finally, when considering the actions required to improve the health of a community, we emphasize the benefits of health promotion, in the genuine sense of the term, by reflecting on effectiveness and efficiency. The question of whether the failure of an intervention to improve health is due to the futility of the action, or to be action being undertaken in an inefficient way, is discussed

Framework and Methodology for Establishing Port-City Policies Based on Real-Time Composite Indicators and IoT: A Practical Use-Case

[EN] During the past few decades, the combination of flourishing maritime commerce and urban population increases has made port-cities face several challenges. Smart Port-Cities of the future will take advantage of the newest IoT technologies to tackle those challenges in a joint fashion from both the city and port side. A specific matter of interest in this work is how to obtain reliable, measurable indicators to establish port-city policies for mutual benefit. This paper proposes an IoTbased software framework, accompanied with a methodology for defining, calculating, and predicting composite indicators that represent real-world phenomena in the context of a Smart PortCity. This paper envisions, develops, and deploys the framework on a real use-case as a practice experiment. The experiment consists of deploying a composite index for monitoring traffic congestion at the port-city interface in Thessaloniki (Greece). Results were aligned with the expectations, validated through nine scenarios, concluding with delivery of a useful tool for interested actors at Smart Port-Cities to work over and build policies upon.This research was funded, by the European Commission, via the agency INEA, under the H2020-project PIXEL, grant number 769355, and, when applicable, by the H2020-project DataPorts, grant number 871493, via the DG-CONNECT agency.Lacalle, I.; Belsa, A.; Vaño, R.; Palau Salvador, CE.

Vesicle formation induced by thermal fluctuations

The process of fission and vesicle formation depends on the geometry of the membrane that will split. For instance, a flat surface finds it difficult to form vesicles because of the lack of curved regions where to start the process. Here we show that vesicle formation can be promoted by temperature, by using a membrane phase field model with Gaussian curvature. We find a phase transition between fluctuating and vesiculation phases that depends on temperature, spontaneous curvature, and the ratio between bending and Gaussian moduli. We analysed the energy dynamical behaviour of these processes and found that the main driving ingredient is the Gaussian energy term, although the curvature energy term usually helps with the process as well. We also found that the chemical potential can be used to investigate the temperature of the system. Finally we address how temperature changes the condition for spontaneous vesiculation for all geometries, making it happen in a wider range of values of the Gaussian modulus.Comment: 31 pages, 10 figure

Fast self-reconfigurable embedded system on Spartan-3

Many image-processing algorithms require several stages to be processed that cannot be resolved by embedded microprocessors in a reasonable time, due to their high-computational cost. A set of dedicated coprocessors can accelerate the resolution of these algorithms, alt hough the main drawback is the area needed for their implementation. The main advantage of a reconfigurable system is that several coprocessors designed to perform different operations can be mapped on the same area in a time-multiplexed way. This work presents the architecture of an embedded system composed of a microprocessor and a run-time reconfigurable coprocessor, mapped on Spartan-3, the low-cost family of Xilinx FPGAs. Designing reconfigurable systems on Spartan-3 requires much design effort, since unlike higher cost families of Xilinx FPGAs, this device does not officially support partial reconfiguration. In order to overcome this drawback, the paper also describes the main steps used in the design flow to obtain a successful design. The main goal of the presented architecture is to reduce the coprocessor reconfiguration time, as well as accelerate image-processing algorithms. The experimental results demonstrate significant improvement in both objectives. The reconfiguration rate nearly achieves 320 Mb/s which is far superior to th e previous related works.Peer ReviewedPostprint (published version
