Geography and retail store location are inherently bound together; this study links food retail changes to systemic logistics changes in an emerging market. Current logistic practices underplay demand-led models and online market evolution in large metropolises such as Istanbul, Rio de Janeiro, and Delhi. The later include raising income and education, access to a wide range of technologies, traffic and transport difficulties, lagging retail provision, changing family structure and roles, as well as changing food culture and taste. The study incorporates demand for premium products defined by Kapferer and Bastien, (2009b) as comprising a broad variety of higher quality and unique or distinctive products and brands including in grocery organic ranges, healthy options, allergy free selections, and international and gourmet/specialty products through an online grocery model (n=356) that integrates a novel view of home delivery (HD) in Istanbul. More importantly from a logistic perspective our model incorporates any products from any online vendors broadening the range beyond listed items found in any traditional online supermarkets. Data collected via phone survey and analysed via structural equation modelling (SEM) suggest that the offer of online premium products significantly affects consumers’ delivery logistics expectations. We discuss logistics operations and business management implications, identifying the emerging geography of logistic models which respond to consumers’ unmet expectations using multiple sourcing and consolidation points.

El libro "Cachamanta runapaj jambi" ha sido elaborado por la Dra. Gloria Acero, al año siguiente de haber cumplido el compromiso de medicina rural en Cacha y por la Sra. María Adelina Pianalto, voluntaria italiana quien viene trabajando en dicha zona durante ocho años. Quienes estamos en contacto permanente con el sector indígena sabemos cuanta paciencia y dedicación hay que tener para incursionar en un campo tan misterioso y reservado como es el de la medicina autóctona, sabiendo por otra parte, que no hay investigaciones similares que se hayan publicado en la provincia del Chimborazo. Una lectura atenta de este libro nos da la impresión de estar ante una cultura distinta a la nuestra, en un mundo que no encaja en nuestros criterios. Lógicamente afloran muchísimos interrogantes: ¿Qué son las enfermedades en la mentalidad del indígena? ¿Cuáles son sus causas?. Porque las curaciones se enmarcan en condiciones estrictas de tiempo, lugar, oraciones, exorcismos, etc.. La medicación es de la mas extraña y sorprendente a nuestro modo de pensar: frente a los comprimidos, inyecciones y frasquitos asépticos, que nos dan las farmacias, están los remedios del campo que se venden en mercados abiertos: gajos de hierbas, minerales, mejunjes, seres vivos y elementos de estos seres: pelos, orina, uñas, gusanos, animales exóticos.

We report on measurements of the adiabatic temperature change in the inverse magnetocaloric Ni50Mn34In16 alloy. It is shown that this alloy heats up with the application of a magnetic field around the Curie point due to the conventional magnetocaloric effect. In contrast, the inverse magnetocaloric effect associated with the martensitic transition results in the unusual decrease of temperature by adiabatic magnetization. We also provide magnetization and specific heat data which enable to compare the measured temperature changes to the values indirectly computed from thermodynamic relationships. Good agreement is obtained for the conventional effect at the second-order paramagnetic-ferromagnetic phase transition. However, at the first-order structural transition the measured values at high fields are lower than the computed ones. Irreversible thermodynamics arguments are given to show that such a discrepancy is due to the irreversibility of the first-order martensitic transition.
