Características de liderazgo de los gerentes de la generación “baby boomers” y propuesta de plan de mejora de toma de decisiones estratégicas y eficacia, caso de estudio Global Engineering S.A.

El presente documento analiza las características de liderazgo de los gerentes “baby boomers” de la empresa transnacional Global Engineering S.A., que tiene oficinas en España, Cuba, Venezuela y Ecuador. Esta investigación se realiza sobre la premisa que los Gerentes de las cuatro oficinas pertenecen a la generación de los baby boomers, por lo se presenta la hipótesis de que, al pertenecer a una misma generación las características de liderazgo son similares. Los objetivos de la presente investigación, fueron el identificar las características de liderazgo de los gerentes, analizarlas, verificar si son eficaces, identificar las oportunidades de mejora y presentar un plan de mejora para la organización. Al presente estudio se lo define como exploratorio, descriptivo y correlacional, se utiliza como herramienta principal para la investigación el MLQ 5X versión corta creado por Bass y Avolio y adaptado por Vega y Zabala, se lo aplica a las cuatro oficinas de la empresa tanto a los gerentes como a los seguidores. Para la comprobación de la hipótesis, se utilizó la prueba t de Student, para establecer valores máximos y mínimos de los promedios de las características de liderazgo, para de esa manera conocer si los Gerentes de cada oficina tienen las mismas características, también se promediaron los valores resultantes de cada estilo de liderazgo para conocer si son eficaces para la realidad de la organización. Como herramienta para la mejora de toma de decisiones estratégica, se presenta el Cuadro de Mando integral, se establecen los objetivos principales para las perspectivas y se señalan los pasos de cómo debe ser el proceso de implementación del plan de coaching gerencial para la organización. De la investigación realizada se concluye que las características de liderazgo de los gerentes de la organización no se relacionan directamente con la generación a la que pertenecen, sino, dependen más del entorno, la situación y de los seguidores. Se recomienda la implementación del Cuadro de Mando Integral para mejorar la toma de decisiones estratégicas, haciendo énfasis en la propuesta de valor de implementar un plan de coaching gerencial para los gerentes de las distintas oficinas para así mejorar la eficacia de la organización.

Advances in Model-Based Traffic Vision

Model based vision allows use of prior knowledge of the shape and appearance of specific objects to be used in the interpretation of a visual scene; it provides a powerful and natural way to enforce the view consistency constraint. A model based vision system has been developed within ESPRIT VIEWS: P2152 which is able to classify and track moving objects (cars and other vehicles) in complex, cluttered traffic scenes. The fundamental basis of the method has been previously reported. This paper presents recent developments which have extended the scope of the system to include (i) multiple cameras, (ii) variable camera geometry, and (iii) articulated objects. All three enhancements have easily been accommodated within the original model-based approach

An Integrated Traffic and Pedestrian Model_based Vision System

The paper describes a novel integrated vision system in which two autonomous visual modules are combined to interpret a dynamic scene. The first module employs a 3D model-based scheme to track rigid objects such as vehicles. The second module uses a 2D deformable model to track non-rigid objects such as people. The principal contribution is a novel method for handling occlusion between objects within the context of this hybrid tracking system. The practical aim of the work is to derive a scene description that is sufficiently rich to be used in a range of surveillance tasks. The paper describes each of the modules in outline before detailing the method of integration and the handling of occlusion in particular. Experimental results are presented to illustrate the performance of the system in a dynamic outdoor scene involving cars and people.

Opportunities for improvements in flocking models

Flocking is the capacity of coherent movement between multiple animals, including birds. Prominent research into flocking is presented. Particle Swarm Optimisation (PSO) has been the prominent result from research into flocking. It is considered that opportunities for further research in flocking exist. With the potential for automated traffic systems, it is concluded that flocking should be reinvestigated for this purpose.

A field study of factors influencing the concentrations of a traffic-related pollutant in the vicinity of a complex urban junction

The paper describes a field study focused on the dispersion of a traffic-related pollutant within an area close to a busy intersection between two street canyons in Central London. Simultaneous measurements of airflow, traffic flow and carbon monoxide concentrations ([CO]) are used to explore the causes of spatial variability in [CO] over a full range of background wind directions. Depending on the roof-top wind direction, evidence of both flow channelling and recirculation regimes were identified from data collected within the main canyon and the intersection. However, at the intersection, the merging of channelled flows from the canyons increased the flow complexity and turbulence intensity. These features, coupled with the close proximity of nearby queuing traffic in several directions, led to the highest overall time-average measured [CO] occurring at the intersection. Within the main street canyon, the data supported the presence of a helical flow regime for oblique roof-top flows, leading to increased [CO] on the canyon leeward side. Predominant wind directions led to some locations having significantly higher diurnal average [CO] due to being mostly on the canyon leeward side during the study period. For all locations, small changes in the background wind direction could cause large changes in the in-street mean wind angle and local turbulence intensity, implying that dispersion mechanisms would be highly sensitive to small changes in above roof flows. During peak traffic flow periods, concentrations within parallel side streets were approximately four times lower than within the main canyon and intersection which has implications for controlling personal exposure. Overall, the results illustrate that pollutant concentrations can be highly spatially variable over even short distances within complex urban geometries, and that synoptic wind patterns, traffic queue location and building topologies all play a role in determining where pollutant hot spots occur.
