Internacionalizacion de las empresas colombianas casos de estudio: Hamburguesas el corral y Pan pa' ya

Con el presente trabajo se pretende describir el plan estratégico internacional que siguió PAN PA’ YA! y HAMBURGUESAS EL CORRAL en el proceso de exportación de sus productos y formalización de la comercialización a nivel internacional, mediante la formación de alianzas entre empresas y distribuidores del mercado. Por medio de un estudio de las diferentes teorías de internacionalización se pudo identificar el proceso a través del cual las empresas colombianas iniciaron sus operaciones en el extranjero. PAN PA’ YA! empezó con el sueño de ser una de las panaderías más grandes en Colombia, hoy en día constituye un negocio integral. Con el paso de los años y el movimiento diario del mercado colombiano la empresa se ha consolidado fuertemente. La mayor parte del éxito es la novedad y el interés de abrirse a mercados satisfaciendo las necesidades de los clientes y siguiendo un modelo de internacionalización en las grandes cadenas, por medio de sus productos listos para calentar. De la misma manera HAMBURGUESAS EL CORRAL gracias al estilo original y único de su decoración, nació y sigue siendo reconocido y apreciado por clientes como una marca de tradición que ha buscado posicionarse con el lema “la receta original”, y ello ha resultado en un concepto casero y único, cuyo compromiso ha sido satisfacer los gustos, expectativas y necesidades de sus clientes con una excelente calidad buscando así un modelo de internacionalización que los consolide en el exterior. Finalmente el proceso de internacionalización que siguieron las empresas Colombianas, se caracteriza por ser un proceso por etapas donde muestran detalle a detalle sus inicios, como lograron la posición dentro del país y como se han establecido en el exterior. Realizando para ello una investigación de mercado adecuada con el objetivo de satisfacer las necesidades del cliente con estrategias de innovación e ideas originales y prácticas.The present work describes the international strategic plan that followed PAN PA’ YA! and HAMBURGUESAS EL CORRAL in the process of exporting products and formalizing international marketing. This is done the formation of alliances between companies and distributors in the market. By studying different theories of internationalization we can identify the process through which the Colombian companies began their operation abroad. PAN PA’ YA! dreamed of becoming one of the largest bakeries in Colombia. Today it is an integral business. Over the years, with the daily movement of the Colombian market, the company has strongly consolidated. Much of this success can be attributed to the expansion of markets to meet the needs of customers. Follows a pattern of internationalization in the big chains. Their products arrive ready for baking. Similarly HAMBURGUESAS EL CORRAL, thanks to the original and unique style of its decoration, was born. This chain to be recognized and appreciated by customers as a mark of tradition that has sought to brand itself with the slogan "the original recipe.”This has resulted in a home-style concept. The commitment has been to satisfy the tastes, expectations, and needs of its vii customers with excellent quality, this company strives for a model that consolidates internationalization abroad. Finally, the process that the Colombian companies followed has been characterized to be a steps process which shows the details since the beginning, how they achieve their position in the Colombian market and then how they have been established in the international market. In consequence, the companies did an adequate market research with the special goal of satisfying the customers’ needs with original and innovate strategies

Vivienda contemporánea: apuntes para una teoría

Desde hace más de cien años, las reflexiones sobre la vivienda y sobre la arquitectura institucional y pública vienen desarrollándose de forma independiente en lo que respecta a métodos indagatorios, planteamientos teóricos, análisis críticos o sistemas clasificatorios. Hablar hoy de vivienda requiere términos específicos de carácter racional, objetivo, funcional o económico en respuesta a los que hasta hace poco avalaron los recientes dispendios formales y estructurales. El objetivo de la presente propuesta es localizar y analizar algunas de las palabras que empiezan a describir los actuales problemas de vivienda para construir con ellas los fundamentos teóricos que cabe deducir de los propios proyectos y de las ideas que sus arquitectos explicitan y sus críticos aportan, tratando de reconocer procedimientos de renovación proyectual, iniciativas experimentales y recientes concepciones residenciales. Términos como vivienda base, dispersión doméstica, atomización, flexibilidad, neutralidad, post-espacio público, reversibilidad, vivienda-ciudad o hibridación están consolidando nociones asociadas a nuevas formas de habitar que hacen inservibles muchas fórmulas convencionales. Extraer algunas de estas ideas estudiando ciertos conjuntos residenciales puede contribuir a hacer comprensible el panorama de la arquitectura doméstica actual, aportando una teoría propia, distinta a las tan consistentes de la primera mitad del siglo XX, pero reveladora tanto de continuidades con ellas como de novedades o cambios sustanciales de sus significados originales (este es el caso de la flexibilidad) o de completas desapariciones, como la otrora esencial búsqueda del Existenzminimum, hoy sustituida por las esperanzadoras nociones de espacio-extra o más por menos. Nuestro esfuerzo como equipo de investigación está orientado a contribuir con un glosario y, por tanto, un ideario, que ayude a construir la necesaria teoría de la vivienda del nuevo siglo

Application of Tensor Neural Networks to Pricing Bermudan Swaptions

The Cheyette model is a quasi-Gaussian volatility interest rate model widely used to price interest rate derivatives such as European and Bermudan Swaptions for which Monte Carlo simulation has become the industry standard. In low dimensions, these approaches provide accurate and robust prices for European Swaptions but, even in this computationally simple setting, they are known to underestimate the value of Bermudan Swaptions when using the state variables as regressors. This is mainly due to the use of a finite number of predetermined basis functions in the regression. Moreover, in high-dimensional settings, these approaches succumb to the Curse of Dimensionality. To address these issues, Deep-learning techniques have been used to solve the backward Stochastic Differential Equation associated with the value process for European and Bermudan Swaptions; however, these methods are constrained by training time and memory. To overcome these limitations, we propose leveraging Tensor Neural Networks as they can provide significant parameter savings while attaining the same accuracy as classical Dense Neural Networks. In this paper we rigorously benchmark the performance of Tensor Neural Networks and Dense Neural Networks for pricing European and Bermudan Swaptions, and we show that Tensor Neural Networks can be trained faster than Dense Neural Networks and provide more accurate and robust prices than their Dense counterparts.Comment: 15 pages, 9 figures, 2 table

Análisis de los rayos registrados en Canarias en el periodo 2006-2015

En zonas dominadas por centros de altas presiones semipermanentes, como Canarias, el aire descendente, los bajos niveles de humedad por encima de la inversión térmica y la estratificación estable, inhiben las tormentas, pero no completamente. A partir de los rayos registrados en una amplia zona geográfica que engloba las islas Canarias y Madeira y el área oceánica circundante, se analiza la distribución espacial y temporal de los mismos, estimando su densidad y el número de días de tormenta en rejillas de resolución 0,1°, y comparando sus características con las de otras zonas geográficas similares. Seguidamente, se evalúa el comportamiento de algunos parámetros eléctricos de los rayos, como la intensidad, la polaridad y la multiplicidad. A continuación, se trazan algunos rasgos que, con una serie más dilatada, pueden llegar a adquirir rango climatológico. Finalmente, se conjeturan algunas de las claves del peculiar episodio de agosto de 2015

Evaluation of the botanical composition of kikuyu and fescue grasslands associated with white clover during two seasons in the high valleys of Mexico

Objective. To evaluate the botanical composition of grasslands of kikuyu (Cenchrus clandestinus) compared to tall fescue (Lolium arundinaceum cv. Cajun II), each one in association with white clover (Trifolium repens cv. Ladino), in two independent experiments conducted during two seasons, autumn 2018 and winter 2019. Methodology. Two independent experiments under small-scale milk production system (SMPS) were established in the municipality of Aculco, State of Mexico, during autumn 2018 and winter 2019. The botanical composition of grasslands under intensive continuous grazing by breeding cows was evaluated. One grassland planted with tall fescue cv. Cajun II and the other invaded by kikuyu; each grassland was associated with white clover cv. Ladino. The botanical composition of both experiments was analyzed using a complete randomized experimental design. Results. The kikuyu grassland recorded significant differences (p<0.05) with a higher proportion of forage during the winter 2018. Whereas the tall fescue cv. Cajun II grassland recorded a proportion of forage (p<0.05) higher than its proportion of dead tissue during autumn 2019. Study Implications: The study of the botanical composition of mixed grasslands destined for livestock grazing allows to identify, propose and define strategies for forage production facing agroclimatic and management conditions in order to generate a better and higher forage yield. Conclusions: The proportion of kikuyu was higher than that of tall fescue cv. Cajun II during the two seasons and years evaluated. This highlights the adaptability of kikuyu grass under agroecological conditions such as the absence of rains and high temperatures, coupled with the high stocking densities of the milk production systems in the study region

The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment

The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourteenth from SDSS overall (making this, Data Release Fourteen or DR14). This release makes public data taken by SDSS-IV in its first two years of operation (July 2014-2016). Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey (eBOSS); the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data driven machine learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS website (www.sdss.org) has been updated for this release, and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020, and will be followed by SDSS-V.Comment: SDSS-IV collaboration alphabetical author data release paper.

Nightside condensation of iron in an ultra-hot giant exoplanet

Ultra-hot giant exoplanets receive thousands of times Earth's insolation. Their high-temperature atmospheres (>2,000 K) are ideal laboratories for studying extreme planetary climates and chemistry. Daysides are predicted to be cloud-free, dominated by atomic species and substantially hotter than nightsides. Atoms are expected to recombine into molecules over the nightside, resulting in different day-night chemistry. While metallic elements and a large temperature contrast have been observed, no chemical gradient has been measured across the surface of such an exoplanet. Different atmospheric chemistry between the day-to-night ("evening") and night-to-day ("morning") terminators could, however, be revealed as an asymmetric absorption signature during transit. Here, we report the detection of an asymmetric atmospheric signature in the ultra-hot exoplanet WASP-76b. We spectrally and temporally resolve this signature thanks to the combination of high-dispersion spectroscopy with a large photon-collecting area. The absorption signal, attributed to neutral iron, is blueshifted by -11+/-0.7 km s-1 on the trailing limb, which can be explained by a combination of planetary rotation and wind blowing from the hot dayside. In contrast, no signal arises from the nightside close to the morning terminator, showing that atomic iron is not absorbing starlight there. Iron must thus condense during its journey across the nightside.Comment: Published in Nature (Accepted on 24 January 2020.) 33 pages, 11 figures, 3 table
