Análisis de la intención de recompra de eventos infantiles en función de los atributos valorados del servicio en San Martín de Porres

La industria del entretenimiento genera grandes ingresos a nivel mundial y representa un sinnúmero de actividades en donde siempre hay disposición de gasto en todos los niveles socioeconómicos, los eventos infantiles se insertan en esta industria, donde se destinan tiempo y montos de dinero considerables para los cumpleaños de los menores hijos. En el contexto peruano se denota que las familias limeñas tienen como gasto secundario las actividades de esparcimiento, diversión, servicios culturales y de enseñanza. Asimismo, las nuevas tendencias influyen en nuevas necesidades; por lo que, surge un abanico de ofertas que no siempre cumplen con las expectativas de los clientes más exigentes. Es así que los eventos infantiles pasaron de ser una simple celebración de cumpleaños a ser un gran espectáculo infantil, donde las madres, principalmente, y los niños influyen en la decisión de compra de tal servicio. Frente a la atomización del servicio de eventos infantiles y la poca profesionalización de las empresas de este rubro, la presente investigación propone determinar cómo los atributos valorados influyen en la intención de recompra de los clientes de la nueva clase media entre las edades de 25 a 40 años en San Martín de Porres, distrito que ha mostrado un crecimiento constante de negocios y MYPEs, al mismo tiempo que una población de clientes exigentes a la hora de adquirir un bien y/o servicio. La información obtenida tiene la finalidad de generar mayor conocimiento del sector, del consumidor y de sus valoraciones respecto al servicio, una base de información útil para el desarrollo de estrategias comerciales y de marketing efectivas. Para esta investigación se aplicó una metodología mixta que complementa la etapa cualitativa con la cuantitativa. Para ello, se realizaron 20 entrevistas y un focus group que permitieron obtener información sobre el comportamiento del consumidor y los atributos valorados del servicio. Luego, se generó la herramienta cuantitativa en el que se insertaron los atributos hallados en un modelo adaptado de intención de recompra de Hume y Mort (2010). Esta encuesta se realizó a 240 madres de familia del distrito de San Martín de Porres de la nueva clase media en la que se encontró, conforme a los resultados del modelo, que la intención de recompra está influida mayormente por los valores atribuidos a la dimensión central del servicio; es decir, a aspectos del espectáculo o “show” en sí, y en menor medida de los atributos en la dimensión periférica; en otras palabras, atributos complementarios y de soporte. Finalmente, con los resultados obtenidos se ha logrado identificar oportunidades para una mejor comunicación del marketing mix; es decir, que se establezca una estrategia integral, donde los estímulos correctos dirigidos al público objetivo funcionan como un factor clave para el éxito de una empresa de entretenimiento, en este aspecto se encontraron mejoras en cuanto a capacitaciones en atención al cliente, psicología y animación infantil. También, el uso creativo del material de apoyo, así como el uso de juegos didácticos e integradores, contar con desenvolvimiento y presencia escénica, y ofrecer un contenido de animación apropiado para los niños y el ambiente familiar. El servicio ofrecido debe ser diferenciado e innovador, necesitando de un arduo trabajo creativo y profesional por parte de quienes se involucran en el subsector de eventos infantilesTesi

Synthesis of AlCoNi-SiC Composite Prepared by Mechanical Alloying

Extensive researches have been carried out geared towards the ongoing improvement of the properties and performance of materials. Chemical modification and thermo-mechanical processing methods have been able to improve the physical properties of these materials. However, ever increasing demands for better materials that exceed the traditional physical characteristics have led to the design and development of advanced materials. Aluminum based composite materials are leading ones in this area; they are fabricated using various methods, including powder metallurgy processes [1]. Mechanical alloying (MA) is a solid-state powder processing technique involving repeating welding, fracturing, and re-welding of powder particles in a ball mill. Mechanical alloying is a unique process for fabrication of several alloys and advanced materials at room temperature. The traditional materials commonly used SiC, Al2O3 or B4C particles incorporated into the matrix by a variety of processes including powder metallurgy. The properties that are trying to improve are the elastic modulus, enhanced heat and wear resistance [2], and for the case of materials processed properly, improved high cycle fatigue performance [3] relative to the unreinforced matrix. Carbides are interesting materials as reinforcement capability to be applied in several fields in materials science, because their excellent chemical, physical and mechanical properties, they are widely applied in electronic, automotive and aircraft industry. In the field of materials, metal-based composites reinforced with carbides offer the possibility of increasing the mechanical performance of novel materials produced by a wide variety of techniques

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.

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.

Severe early onset preeclampsia: short and long term clinical, psychosocial and biochemical aspects

Preeclampsia is a pregnancy specific disorder commonly defined as de novo hypertension and proteinuria after 20 weeks gestational age. It occurs in approximately 3-5% of pregnancies and it is still a major cause of both foetal and maternal morbidity and mortality worldwide1. As extensive research has not yet elucidated the aetiology of preeclampsia, there are no rational preventive or therapeutic interventions available. The only rational treatment is delivery, which benefits the mother but is not in the interest of the foetus, if remote from term. Early onset preeclampsia (<32 weeks’ gestational age) occurs in less than 1% of pregnancies. It is, however often associated with maternal morbidity as the risk of progression to severe maternal disease is inversely related with gestational age at onset2. Resulting prematurity is therefore the main cause of neonatal mortality and morbidity in patients with severe preeclampsia3. Although the discussion is ongoing, perinatal survival is suggested to be increased in patients with preterm preeclampsia by expectant, non-interventional management. This temporising treatment option to lengthen pregnancy includes the use of antihypertensive medication to control hypertension, magnesium sulphate to prevent eclampsia and corticosteroids to enhance foetal lung maturity4. With optimal maternal haemodynamic status and reassuring foetal condition this results on average in an extension of 2 weeks. Prolongation of these pregnancies is a great challenge for clinicians to balance between potential maternal risks on one the eve hand and possible foetal benefits on the other. Clinical controversies regarding prolongation of preterm preeclamptic pregnancies still exist – also taking into account that preeclampsia is the leading cause of maternal mortality in the Netherlands5 - a debate which is even more pronounced in very preterm pregnancies with questionable foetal viability6-9. Do maternal risks of prolongation of these very early pregnancies outweigh the chances of neonatal survival? Counselling of women with very early onset preeclampsia not only comprises of knowledge of the outcome of those particular pregnancies, but also knowledge of outcomes of future pregnancies of these women is of major clinical importance. This thesis opens with a review of the literature on identifiable risk factors of preeclampsia

Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe

Measurements of the pp → ZZ production cross section and the Z → 4ℓ branching fraction, and constraints on anomalous triple gauge couplings at √s = 13 TeV

Four-lepton production in proton-proton collisions, pp -> (Z/gamma*)(Z/gamma*) -> 4l, where l = e or mu, is studied at a center-of-mass energy of 13 TeV with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 35.9 fb(-1). The ZZ production cross section, sigma(pp -> ZZ) = 17.2 +/- 0.5 (stat) +/- 0.7 (syst) +/- 0.4 (theo) +/- 0.4 (lumi) pb, measured using events with two opposite-sign, same-flavor lepton pairs produced in the mass region 60 4l) = 4.83(-0.22)(+0.23) (stat)(-0.29)(+0.32) (syst) +/- 0.08 (theo) +/- 0.12(lumi) x 10(-6) for events with a four-lepton invariant mass in the range 80 4GeV for all opposite-sign, same-flavor lepton pairs. The results agree with standard model predictions. The invariant mass distribution of the four-lepton system is used to set limits on anomalous ZZZ and ZZ. couplings at 95% confidence level: -0.0012 < f(4)(Z) < 0.0010, -0.0010 < f(5)(Z) < 0.0013, -0.0012 < f(4)(gamma) < 0.0013, -0.0012 < f(5)(gamma) < 0.0013
