    The systemic mind and a conceptual framework for the psychosocial environment of business enterprises: Practical implications for systemic leadership training

    Get PDF
    This chapter introduces a research-based conceptual framework for the study of the inner psychosocial reality of business enterprises. It is called the Inner Organizational Ecosystem Approach (IOEA). This model is systemic in nature, and it defines the basic features of small and medium-size enterprises, such as elements, structures, borders, social actors, organizational climate, processes and resources. Further, it also covers the dynamics of psychosocial reality, processes, emergent qualities and the higher-order subsystems of the overall organizational ecosystem, including the global business environment, which is understood as a macro-system where all the individual organizational ecosystems co-exist. In the applied part of the chapter, cognitive changes emerging within systemic leadership training are defined. Participation in systemic training causes changes in the cognitive processing of reality, more specifically improvements in layer-based framing, relativistic contextual orientation, temporality drift and meaning generation. All of these changes are components of the systemic mind, which is a concept newly proposed and defined by the present study. The systemic mind is a living matrix that is extremely open to acquiring new skills and new patterns of thinking, analyzing and meaning generation. It is processual and it can be considered as an ongoing process of continuous absorption of new cognitive patterns. Both the Inner Organizational Ecosystem Approach and the concept of the systemic mind provide a new theoretical background for empirical investigation in the fields of systemic and systems psychology, complexity psychology, organizational psychology, economic anthropology and the social anthropology of work

    Robot friendly connectors, which, in one aspect, are truss joints with two parts, a receptacle and a joint, are presented. The joints have a head which is loosely inserted into the receptacle and is then tightened and aligned. In one aspect, the head is a rounded hammerhead which initially is enclosed in the receptacle with sloppy fit provided by the shape, size, and configuration of surfaces on the head and on the receptacle

    El patrimonio cultural inmigratorio y su uso como recurso turístico

    Get PDF
    El patrimonio cultural y el turismo tienen una relación de larga data. Desde los comienzos de la actividad, los distintos elementos patrimoniales han sido el sustento de muchos destinos turísticos. Nuestro país, la Argentina, no es una excepción a esta afirmación, ya que muchos destinos basan su oferta turística en su patrimonio cultural. Los distintos flujos migratorios que llegaron al país entre fines de siglo XIX y mediados de siglo XX han sido muy importantes para su desarrollo. El impacto de los mismos sobre la población, sobretodo en términos porcentuales, ha determinado parte de nuestra identidad y, por ende, de nuestros referentes patrimoniales. El siguiente trabajo plantea la relación entre estos dos fenómenos para entender así la forma en la que el patrimonio cultural inmigratorio puede servir como recurso para la conformación de productos turísticos en destinos nacionales. Para esto, se establecerán tres casos de éxito en este ámbito y se indagará sobre las acciones que se han llevado a cabo para llegar a esa situación. A su vez, el análisis también abarcará el caso ciudad de Berisso. La misma, lugar de llegada de una cantidad elevada de inmigrantes durante varias décadas, ha determinado la identidad del territorio a través del encuentro de diferentes culturas. La ciudad cuenta con muchos elementos patrimoniales en relación a los inmigrantes, pero la mayoría no están insertos actualmente en la actividad turística. Mediante la comparación con los casos éxitos planteados, se establecerán diferencias y similitudes obteniendo así un modelo de referencia para la conformación de productos turísticos culturales en base a estos recursos.Eje temático: Identificación y uso de recursos turístico

    Development of a truss joint for robotic assembly of space structures

    This report presents the results of a detailed study of mechanical fasteners which were designed to facilitate robotic assembly of structures. Design requirements for robotic structural assembly were developed, taking into account structural properties and overall system design, and four candidate fasteners were designed to meet them. These fasteners were built and evaluated in the laboratory, and the Hammer-Head joint was chosen as superior overall. It had a high reliability of fastening under misalignments of 2.54 mm (0.1 in) and 3 deg, the highest end fixity (2.18), the simplest end effector, an integral capture guide, good visual verification, and the lightest weight (782 g, 1.72 lb). The study found that a good design should incorporate chamfers sliding on chamfers, cylinders sliding on chamfers, and hard surface finishes on sliding surfaces. The study also comments on robot flexibility, sag, hysteresis, thermal expansion, and friction which were observed during the testing

    Relativistic jet models for two low-luminosity radio galaxies: evidence for backflow?

    Full text link
    We show that asymmetries in total intensity and linear polarization between the radio jets and counter-jets in two lobed Fanaroff-Riley Class I (FR I) radio galaxies, B2 0206+35 (UGC 1651) and B2 0755+37 (NGC 2484), can be accounted for if these jets are intrinsically symmetrical, with decelerating relativistic outflows surrounded by mildly relativistic backflows. Our interpretation is motivated by sensitive, well-resolved Very Large Array imaging which shows that both jets in both sources have a two-component structure transverse to their axes. Close to the jet axis, a centrally-darkened counter-jet lies opposite a centrally-brightened jet, but both are surrounded by broader collimated emission that is brighter on the counter-jet side. We have adapted our previous models of FR I jets as relativistic outflows to include an added component of symmetric backflow. We find that the observed radio emission, after subtracting contributions from the extended lobes, is well described by models in which decelerating outflows with parameters similar to those derived for jets in plumed FR I sources are surrounded by backflows containing predominantly toroidal magnetic fields. These return to within a few kpc of the galaxies with velocities of roughly 0.25c and radiate with a synchrotron spectral index close to 0.55. We discuss whether such backflow is to be expected in lobed FR I sources and suggest ways in which our hypothesis can be tested by further observations.Comment: 22 pages, 17 figures, accepted for publication in MNRA

    Choosing life: the myth of Er in Plato’s Republic

    Get PDF
    El artículo se propone mostrar cómo, en el mito de Er, Platón explora las condiciones desde las cuales las almas, antes de la encarnación, deciden cómo van a vivir su próxima vida. El énfasis se pone en la fuerte influencia que Platón le otorga al pasado al momento de tomar una nueva decisión; y esto implica que la vida puede convertirse en un ciego repetirse de lo pasado, sin conciencia de ello. Por otro lado, junto a la crítica de la repetición, el filósofo denuncia las decisiones que se toman desde el hábito y sin la reflexión que exige la filosofía. Así, sostendrá Sócrates, uno y otro caso, que conduce las decisiones al error, pueden evitase sólo a través de la filosofía.The paper aims to show how, in the Myth of Er, Plato explores the conditions from which souls before incarnation, decide how they will live their next life. The emphasis is strongly influenced Plato gives the past when making a new decision; and this implies that life can become a repeat of the past blind, unaware of it. Furthermore, with the criticism of repetition, the philosopher denounces the decisions made from the habit without requiring reflection philosophy. So hold Socrates either case, the decisions leading to the error can avoided only through philosophy

    Nacelle design

    Get PDF
    The external cowlings of engine nacelles on large turbofan powered aircraft are good candidates for application of natural laminar flow. These nacelles usually have shorter characteristic lengths than other candidate surfaces such as wings and fuselages and therefore have lower characteristic Reynolds numbers. A conceptive figure of the natural flow nacelle (NLF) is shown. On the typical nacelle the flow accelerates to a curvature induced velocity peak near the lip and then decelerates over the remainder of the nacelle length. Transition occurs near the start of the deceleration, so turbulent flow with high friction coefficient exists over most of the nacelle length. On the other hand, the NLF nacelle is contoured to have an accelerating flow over most of its length, so transition is delayed, and a relatively lower friction drag exists over most of the nacelle. The motivation for development of the LFN is a potential 40 to 50 percent reduction in nacelle friction drag

    Static Heat Loads in the LHC Arc Cryostats: Final Assessment

    Get PDF
    This note presents the final assessment of the static heat loads in the LHC arc cryostats, using different experimental methods during the first commissioning period in 2007. This assessment further develops and completes previous estimates made during the commissioning of sector 7_8 [1]. The estimate of the helium inventory, a prerequisite for the heat load calculation, is also presented. Heat loads to the cold mass are evaluated from the internal energy balance during natural as well as powered warm-ups of the helium baths in different subsector. The helium inventory is calculated from the internal energy balance during powered warm-ups and matched with previous assessments. Furthermore, heat loads to the thermal shield are estimated from the non-isothermal cooling of the supercritical helium in line E. The comparison of measured heat loads with previous estimates and with budgeted values is then presented, while their correlation with some important parameters like insulation vacuum pressure and some heat interception temperatures is proposed and discussed

    Series-produced Helium II Cryostats for the LHC Magnets: Technical Choices, Industrialisation, Costs

    Get PDF
    Assembled in 8 continuous segments of approximately 2.7 km length each, the He II cryostats for the 1232 cryodipoles and 474 Short Straight Sections (SSS housing the quadrupoles) must fulfil tight technical requirements. They have been produced by industry in large series according to cost-effective industrial production methods to keep expenditure within the financial constraints of the project and assembled under contract at CERN. The specific technical requirements of the generic systems of the cryostat (vacuum, cryogenic, electrical distribution, magnet alignment) are briefly recalled, as well as the basic design choices leading to the definition of their components (vacuum vessels, thermal shielding, supporting systems). Early in the design process emphasis was placed on the feasibility of manufacturing techniques adequate for large series production of components, optimal tooling for time-effective assembly methods, and reliable quality assurance systems. An analytical review of the costs of the cryostats from component procurement to final assembly, tests and interconnection in the machine is presented and compared with initial estimates, together with an appraisal of the results and lessons learned
