The systemic mind and a conceptual framework for the psychosocial environment of business enterprises: Practical implications for systemic leadership training
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
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
Nacelle design
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
Robot-friendly connector
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
Relativistic jet models for two low-luminosity radio galaxies: evidence for backflow?
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
El patrimonio cultural inmigratorio y su uso como recurso turÃstico
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 turÃsticos. Nuestro paÃs, la Argentina, no es una excepción a esta afirmación, ya que muchos destinos basan su oferta turÃstica en su patrimonio cultural.
Los distintos flujos migratorios que llegaron al paÃs 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 asà la forma en la que el patrimonio cultural inmigratorio puede servir como recurso para la conformación de productos turÃsticos 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 mayorÃa no están insertos actualmente en la actividad turÃstica. Mediante la comparación con los casos éxitos planteados, se establecerán diferencias y similitudes obteniendo asà un modelo de referencia para la conformación de productos turÃsticos culturales en base a estos recursos.Eje temático: Identificación y uso de recursos turÃstico
Cryostat Design
This paper aims to give non-expert engineers and scientists working in the
domain of accelerators a general introduction to the main disciplines and
technologies involved in the design and construction of accelerator cryostats.
Far from being an exhaustive coverage of these topics, an attempt is made to
provide simple design and calculation rules for a preliminary design of
cryostats. Recurrent reference is made to the Large Hadron Collider magnet
cryostats, as most of the material presented is taken from their design and
construction at CERN.Comment: 47 pages, contribution to the CAS-CERN Accelerator School:
