Founder's influence on the creation of the organizational culture and its impact on the sustainability of a family business

[ESP] Las empresas de familia son eje importante del funcionamiento de una economía y la forma como se diseñan, es clave del funcionamiento y duración en el tiempo. En 2009 en Colombia cerca del 70% de las empresas eran familiares, según la Superintendencia de Sociedades, con baja participación en indicadores económicos generales. Cerca del 72,8% de estas empresas fueron fundadas después de 1970 (Dinámica EF FUNDES) y estudios de 2003, indicaban que generaban el 73% del empleo y el 53% de la producción bruta de los principales sectores (Jaramillo, 2005). El presente caso presenta, situaciones organizacionales de la empresa Trujillo Ortiz y Compañía S. En C., creada en 1985, durante su auge hasta 1998 y su final, a partir del 2000, presentando características organizacionales y valores de su principal orientador, mostrando como éstos y su influencia en la organización determinaron que la empresa llegue al final este año. [ENG] Family businesses are an important part of the functioning of one economy, and how this is constructed is one of the keys to its performance on time. In 2009 in Colombia about 70% of companies were family owned, according to Superintendencia de Sociedades with a low participation in economic metrics. About 72.8 % were founded after 1970 (Dynamic EF FUNDES), and 2003 surveys indicated that they generated 73% of national employment and 53% of the gross production of main economic sectors (Jaramillo, 2005). This case outlines organizational situations experienced by Trujillo Ortiz y Compañía S. en C., founded in 1985, during its rise until 1998, and its end, since 2000, showing the organizational characteristics and values of their main guiding, presenting how these, and their influence in the organization, determined the end of the company in this year

Predictors of administrative innovation: functions and organizational methods - Mexican and Colombian hospitals

Objectiv e To determine to what extent functions and organizational methods influence on administrative innovation. Design/methodology/approach This research is quantitative approach, with a not experimental and transversal design. The hypothesis was supported by using a transactional study with a sample of Mexican and Colombian hospitals through the perception of their high and medium level managers. The hospital sampling was by convenience. Findings Organizational functions and methods are associated and are predictors of administrative innovation. Practical implications As long as the hospital encourages the development of training and knowledge methods, autonomy methods for employees are developed, and when performance appraisal takes place in hospital, new methods will be able to develop and organize the routines and the management procedures, allocation of responsibilities and power among employees could be developed, as well as to develop new structure concepts for workplace, organizational practices and external relationships

Competencias para el ejercicio de la dirección de instituciones educativas : reflexiones y experiencias en Iberoamérica

El presente texto es el resultado de las aportaciones al encuentro realizado por los miembros de la Red de Apoyo a la Gestion Educativa (http://www.redage.org) en junio de 2011 en la ciudad de Lima. Constituye el tercer documento de la Serie Informes que ha producido la RedAGE y es expresión del compromiso constitutivo por analizar y difundir temáticas relacionadas con la organizaciÓn y dirección de los sistemas y centros educativos. El ejercicio directivo analizado desde la perspectiva de las competencias es la temática que se aborda en esta ocasión. Por una parte, se continúa la reflexión iniciada con el segundo informe, dedicado a la Dirección de centros educativos en Iberoamérica (http://www.redage.org/files/adjuntos/ Libro%20Red_AGE%20vd.pdf); por otra, se profundiza desde la perspectiva de las competencias con la idea de difundir e impulsar el nuevo enfoque. Tratamos así de un tema incipiente en algunos de los países, pero presente y parte de la agenda de los responsables de la política educativa, con la idea de aportar elementos para las posibles acciones a desarrollar o a mejorar al respecto. Hablamos de competencias y sobre competencias1 y con ello nos referimos a las características de la persona relacionadas con una actuación de éxito en su lugar de trabajo. Se identifican así con la activación y aplicación de manera coordinada de elementos de diferente naturaleza (cognoscitivos, afectivos y procedimentales) para resolver situaciones profesionales concretas. El concepto de competencia es utilizado desde hace tiempo en el campo de la formación profesional, abriéndose camino, poco a poco, en todo el sistema educativo y en los procesos de formación continua, donde la gestión por competencias se ha convertido en un modelo integrador y orientador de las diferentes políticas de recursos humanos

Measurement of the cosmic ray spectrum above 4×10184{\times}10^{18} eV using inclined events detected with the Pierre Auger Observatory

A measurement of the cosmic-ray spectrum for energies exceeding $4{\times}10^{18}$ eV is presented, which is based on the analysis of showers with zenith angles greater than $60^{\circ}$ detected with the Pierre Auger Observatory between 1 January 2004 and 31 December 2013. The measured spectrum confirms a flux suppression at the highest energies. Above $5.3{\times}10^{18}$ eV, the "ankle", the flux can be described by a power law $E^{-\gamma}$ with index $\gamma=2.70 \pm 0.02 \,\text{(stat)} \pm 0.1\,\text{(sys)}$ followed by a smooth suppression region. For the energy ($E_\text{s}$) at which the spectral flux has fallen to one-half of its extrapolated value in the absence of suppression, we find $E_\text{s}=(5.12\pm0.25\,\text{(stat)}^{+1.0}_{-1.2}\,\text{(sys)}){\times}10^{19}$ eV.Comment: Replaced with published version.

Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory

The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared to the data of the surface detector stations of the Observatory, which provide well-calibrated information on the cosmic-ray energies and arrival directions. The response of the radio stations in the 30 to 80 MHz regime has been thoroughly calibrated to enable the reconstruction of the incoming electric field. For the latter, the energy deposit per area is determined from the radio pulses at each observer position and is interpolated using a two-dimensional function that takes into account signal asymmetries due to interference between the geomagnetic and charge-excess emission components. The spatial integral over the signal distribution gives a direct measurement of the energy transferred from the primary cosmic ray into radio emission in the AERA frequency range. We measure 15.8 MeV of radiation energy for a 1 EeV air shower arriving perpendicularly to the geomagnetic field. This radiation energy -- corrected for geometrical effects -- is used as a cosmic-ray energy estimator. Performing an absolute energy calibration against the surface-detector information, we observe that this radio-energy estimator scales quadratically with the cosmic-ray energy as expected for coherent emission. We find an energy resolution of the radio reconstruction of 22% for the data set and 17% for a high-quality subset containing only events with at least five radio stations with signal.Comment: Replaced with published version.

Measurement of the Radiation Energy in the Radio Signal of Extensive Air Showers as a Universal Estimator of Cosmic-Ray Energy

We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Auger Observatory, we obtain a radiation energy of 15.8 \pm 0.7 (stat) \pm 6.7 (sys) MeV for cosmic rays with an energy of 1 EeV arriving perpendicularly to a geomagnetic field of 0.24 G, scaling quadratically with the cosmic-ray energy. A comparison with predictions from state-of-the-art first-principle calculations shows agreement with our measurement. The radiation energy provides direct access to the calorimetric energy in the electromagnetic cascade of extensive air showers. Comparison with our result thus allows the direct calibration of any cosmic-ray radio detector against the well-established energy scale of the Pierre Auger Observatory.Comment: Replaced with published version.

A search for ultra-high-energy photons at the Pierre Auger Observatory exploiting air-shower universality

The Pierre Auger Observatory is the most sensitive detector to primary photons with energies above ∼0.2 EeV. It measures extensive air showers using a hybrid technique that combines a fluorescence detector (FD) with a ground array of particle detectors (SD). The signatures of a photon-induced air shower are a larger atmospheric depth at the shower maximum (X$_{max}$) and a steeper lateral distribution function, along with a lower number of muons with respect to the bulk of hadron-induced background. Using observables measured by the FD and SD, three photon searches in different energy bands are performed. In particular, between threshold energies of 1-10 EeV, a new analysis technique has been developed by combining the FD-based measurement of X$_{max}$ with the SD signal through a parameter related to its muon content, derived from the universality of the air showers. This technique has led to a better photon/hadron separation and, consequently, to a higher search sensitivity, resulting in a tighter upper limit than before. The outcome of this new analysis is presented here, along with previous results in the energy ranges below 1 EeV and above 10 EeV. From the data collected by the Pierre Auger Observatory in about 15 years of operation, the most stringent constraints on the fraction of photons in the cosmic flux are set over almost three decades in energy
