Lealtad a la práctica deportiva: Una aplicación de la TPB a los servicios públicos para la práctica deportiva

The Theory of Planned Behavior (TPB) has been used in multiple industries and markets to explain the behavior of individuals. In the Colombian sports sector has never been used as a tool to model the behavior of individuals loyal to the sports offered by public institutions.In this study, the TPB model is proposed as a hypothesis to explain the history of loyalty to the sport, an empirical sample of 411 users of the programs of sport and physical activity INDERE (La Estrella, Antioquia) is collected, run a confirmatory factor analysis to ensure the reliability and validity of the measurement model and the hypotheses are tested by structural equation modeling.The study showed that TPB provides a good fit to model the behavior of loyalty to the sport and concluded that Perceived Control is the main antecedent of loyalty to sports such programs.La Teoría del Comportamiento Planificado (TPB) ha sido utilizada en múltiples sectores y mercados para explicar el comportamiento de los individuos.

Source model of the 2007 M_w 8.0 Pisco, Peru earthquake: Implications for seismogenic behavior of subduction megathrusts

We use Interferometric Synthetic Aperture Radar, teleseismic body waves, tsunami waveforms recorded by tsunameters, field observations of coastal uplift, subsidence, and runup to develop and test a refined model of the spatiotemporal history of slip during the M_w 8.0 Pisco earthquake of 15 August 2007. Our preferred solution shows two distinct patches of high slip. One patch is located near the epicenter while another larger patch ruptured 60 km further south, at the latitude of the Paracas peninsula. Slip on the second patch started 60 s after slip initiated on the first patch. We observed a remarkable anticorrelation between the coseismic slip distribution and the aftershock distribution determined from the Peruvian seismic network. The proposed source model is compatible with regional runup measurements and open ocean tsunami records. From the latter data set, we identified the 12 min timing error of the tsunami forecast system as being due to a mislocation of the source, caused by the use of only one tsunameter located in a nonoptimal azimuth. The comparison of our source model with the tsunami observations validate that the rupture did not extend to the trench and confirms that the Pisco event is not a tsunami earthquake despite its low apparent rupture velocity (<1.5 km/s). We favor the interpretation that the earthquake consists of two subevents, each with a conventional rupture velocity (2–4 km/s). The delay between the two subevents might reflect the time for the second shock to nucleate or, alternatively, the time it took for afterslip to increase the stress level on the second asperity to a level necessary for static triggering. The source model predicts uplift offshore and subsidence on land with the pivot line following closely the coastline. This pattern is consistent with our observation of very small vertical displacement along the shoreline when we visited the epicentral area in the days following the event. This earthquake represents, to our knowledge, one of the best examples of a link between the geomorphology of the coastline and the pattern of surface deformation induced by large interplate ruptures

Lower Aptian ammonite and carbon isotope stratigraphy in the eastern Prebetic Domain (Betic Cordillera, southeastern Spain)

Major global palaeobiologic and palaeoenvironmental changes occurred during the Early Aptian. Precise dating and timing of the different events is crucial to determine possible cause-effect relationships between them. In this regard, the combination of biostratigraphic and chemostratigraphic data can provide a very useful tool for time control. So far attempts to correlate the Lower Aptian carbon isotope record and the ammonite zonation yielded contradictory conclusions. In this paper, we present the results of an integrated analysis of the ammonite stratigraphic distribution and highresolution carbon isotope profiles from Lower Aptian sections of the eastern Prebetic Domain (Betic Cordillera, southeastern Spain). We recognized, in ascending order, the Deshayesites oglanlensis, Deshayesites forbesi, Deshayesites deshayesi, and Dufrenoyia furcata Zones. This succession is the same as that recently identified in the eastern Iberian Chain, and it closely correlates with both standard Mediterranean and Boreal zonations. The carbon isotope record displays the trends globally recognized for the Early Aptian, with two long positive shifts separated by a pronounced negative excursion. Calibration of this isotopic record with the ammonite zonation shows that the age of OAE 1a, which corresponds to the negative excursion and subsequent positive shift, is constrained to the middle/upper part of the Deshayesites forbesi Zone

Design, modelling and optimisation of a small-scale Solar Organic Rankine Cycle system for rural power generation

This research study develops the design and model of a Solar Organic Rankine Cycle (SORC) coupled to a bio-digester for small-scale generation in rural areas, in Betulia, Colombia. Moreover, the model is optimised employing a Genetic Algorithm with the software Matlab and the thermodynamic library CoolProp. The objective variables were the mass flow rate of the working fluid, the pressure and temperature of the expander inlet, the solar collectors’ type and the temperature of the water circuit for the bio-digester. The results indicate an overall efficiency between 8.42 and 9.45% with a Levelized Cost of Energy (LCE) between 3.85 and 5.63 £/W. Additionally, the power output is directly related to the mass flow rate of the working fluid. Likewise, increasing the scale of the SORC decreases the LCE. Finally, the results suggest that a superheated fluid reduces the efficiency and the LCE and can deliver more heat to the bio-digester. It is advisable the utilisation of a scroll expander and a counter-flow plate exchanger with a Direct Vapour Generation configuration. The model is a flexible tool capable of integrating more equations and components, with the evaluation of different fitness functions

Search for the disappearance of muon antineutrinos in the NuMI neutrino beam

We report constraints on antineutrino oscillation parameters that were obtained by using the two MINOS detectors to measure the 7% muon antineutrino component of the NuMI neutrino beam. In the Far Detector, we select 130 events in the charged-current muon antineutrino sample, compared to a prediction of 136.4 ± 11.7(stat)^(+10.2)_(-8.9)(syst) events under the assumption │Δm^2│ = 2.32 X 10^(-3) eV^2, sin^2(2θ) = 1.0

Testing Lorentz Invariance and CPT Conservation with NuMI Neutrinos in the MINOS Near Detector

A search for a sidereal modulation in the MINOS near detector neutrino data was performed. If present, this signature could be a consequence of Lorentz and CPT violation as predicted by a class of extensions to the Standard Model. No evidence for a sidereal signal in the data set was found, implying that there is no significant change in neutrino propagation that depends on the direction of the neutrino beam in a sun-centered inertial frame. Upper limits on the magnitudes of the Lorentz and CPT violating terms in these extensions to the Standard Model lie between 0.01-1% of the maximum expected, assuming a suppression of these signatures by factor of $10^{-17}$.

Recent Innovations & Daily Problems. A new prosthesis in inguinal hernia repair:preliminary results of a pilot study.

Introduction: Elective surgery for inguinal hernia is affected by very low mortality « 1 per 10000 operation); in contrast, when surgery is carried out for complicated inguinal hernia, risks of postoperative complication are higher. TAPP is a world-wide accepted surgical practice in the treatment of elective bilateral or recurrent inguinal hernia, above all in young patients. Few exploratory studies were published on laparoscopic approach in the treatment of urgent complicated inguinal hernia. Aim of this study was to analyze feasibility (operative time, conversion rate), safety (postoperative morbidity, length of hospital stay) and quality of life (acute and chronic pain, return to work) of trans-abdominal pre-peritoneal laparoscopic hernia repair in acute incarcerated inguinal hernia. Rationale of laparoscopic trans-abdominal approach is the easier hernia reduction under vision and a better exploration of the abdominal cavity. Methods: from September 2012 to September 2013, 15 consecutive patients admitted in emergency at the Division of General Surgery of University "Sapienza", Polo Pontino, for acute incarcerated inguinal hernia were submitted to TAPP using 3 trocars (1 of 10 mm and 2 of 5mm) and polyester prosthesis fixed by fibrin glue. Exclusion criteria for laparoscopic approach were age III, previous abdominal surgery, signs of strangulated hernia. All of them were evaluated for operative time, conversion rate, postoperative morbidity, organ resection or other surgery required. All patients were scored for pain by Visual Analogic Scale (VAS) during postoperative in hospital stay at 7 days, 1,6 and 12 months after surgery. Results: median follow-up was 16 months and 12 as minimum. In all cases reduction of hernia was always possible and none conversion to open surgery was recorded, median operative time was 89 minutes (55-137 as range), omental resection was carried out in one patient (6,6%), no other organ resections needed, whereas contralateral hernia was diagnosed and repaired at the same time in 4 patients (26,6%). No major complications were observed, median blood loss was 100 ml, minor morbidity was contained to 18% represented by fever and wound infection of surgical umbilical scar. Median in hospital stay was 1,5 days with 1-5 days as range. Postoperative median acute pain, measured by visual analogic scale (VAS), was 2 (range:0-4), none patient referred any pain during follow-up. Median time of return to work was 6,5 days, ranged between 3 to 15 days. Patients' compliance to treatment and to follow-up was complete as well their satisfaction. Conclusions: In centres skilled for laparoscopy in emergency, TAPP could be considered a feasible and safe technique. In well-selected patients (especially if emolled in controlled clinical trial) TAPP could represent an alternative surgical approach for complicated incarcerated inguinal hernia to conventional open surgery even in urgency. The main advantages of laparoscopic approach are the ability to perform surgical hernia reduction under vision, a better exploration and evaluation of abdominal cavity and diagnosis and treatment of eventual contralateral defect of wall, otherwise often missed. Finally, the good control of acute and chronic pain, faster return to normal activity and work, better aesthetic results contributed to total satisfaction and compliance of the patients
