Aquest projecte de l'àrea d'interacció humana amb els ordinadors vol mostrar algunes de les característiques de tres dels processos que intervenen en la compra de productes o serveis per Internet. Els processos que s'hi analitzaran seran el de cerca de productes mitjançant un motor de cerca, el d'ajuda o atenció al client i el de compra.

La finalitat d'aquest projecte és desenvolupar una aplicació de comerç electrònic per a la venda de productes en la xarxa. El projecte haurà de tenir dues parts ben diferenciades: el frontal -que serà visible per a qualsevol usuari de la xarxa- i la part d'administrador -nomès accessible per a l'administrador-. El projecte estarà desenvolupat amb eines J2EE, Ajax, jQuery i HTML5, oferint una total accessibilitat per als actuals navegadors.

La idea bàsica d'aquest disseny centrat en l'usuari és obtenir informació sobre els usuaris, les seves tasques i objectius, i fer servir tota aquesta informació per orientar el disseny i el desenvolupament de productes. Per a la realització d'aquest treball s'han establert quatre fases: (1) Investigació, (2) Disseny d'escenaris i flux d'interacció, (3) Prototipat, i (4) Avaluació. El cas pràctic que es tractarà és una cadena de supermercats ecològics que vol promocionar la compra responsable d'aliments.

Aquest projecte tracta de la millora de l’actual sistema d’importació que disposa Magento. Actualment per importar els productes a una botiga Magento es necessita treballar amb un fitxer csv on s’introdueix una gran quantitat de dades i requereix una gran quantitat de temps i esforç per part de l’empresa. Per millorar l’actual sistema, es proposa crear una integració entre Magento i Google Docs, fent que tots els productes que es vulguin importar s’introdueixin en un full de càlcul Google Docs i s’importin a la botiga Magento.

This paper advances a highly tractable model with search theoretic foundations for money and neoclassical growth. In the model, manufacturingand commerce are distinct and separate activities. In manufacturing,goods are efficiently produced combining capital and labor. In commerce,goods are exchanged in bilateral meetings. The model is applied to studythe effects of inßation on capital accumulation and welfare. With realisticparameters, inflation has large negative effects on welfare even though itraises capital and output. In contrast, with cash-in-advance, a deviceinformally motivated with bilateral trading, inflation depresses capitaland output and has a negligible effect on welfare.

Despite the important benefits for firms of commercial initiatives on the Internet, e-commerce is still an emerging distribution channel, even in developed countries. Thus, more needs to be known about the mechanisms affecting its development. A large number of works have studied firms¿ e-commerce adoption from technological, intraorganizational, institutional, or other specific perspectives, but there is a need for adequately tested integrative frameworks. Hence, this work proposes and tests a model of firms¿ business-to-consumer (called B2C) e-commerce adoption that is founded on a holistic vision of the phenomenon. With this integrative approach, the authors analyze the joint influence of environmental, technological, and organizational factors; moreover, they evaluate this effect over time. Using various representative Spanish data sets covering the period 1996-2005, the findings demonstrate the suitability of the holistic framework. Likewise, some lessons are learned from the analysis of the key building blocks. In particular, the current study provides evidence for the debate about the effect of competitive pressure, since the findings show that competitive pressure disincentivizes e-commerce adoption in the long term. The results also show that the development or enrichment of the consumers¿ consumption patterns, the technological readiness of the market forces, the firm¿s global scope, and its competences in innovation continuously favor e-commerce adoption.

Since the mid-1990s researchers have sought to understand why some firms embark on e-commerceoperations on the Internet while others prefer to wait and see how events unfold. We still have todetermine which variables contribute to explaining the extent to which firms use e-commerce, giventhat to date the literature has not yet offered conclusive evidence on this question. The current workaims to provide an integrated vision of the set of factors influencing the e-commerce adoptionprocess. We use a sample of 2,038 firms of all types that trade their products either with otherorganizations or with end-consumers.

We present an Analytic Model of Intergalactic-medium and GAlaxy (AMIGA) evolution since the dark ages. AMIGA is in the spirit of the popular semi-analytic models of galaxy formation, although it does not use halo merger trees but interpolates halo properties in grids that are progressively built. This strategy is less memory-demanding and allows one to start modeling at sufficiently high redshifts and low halo masses to have trivial boundary conditions. The number of free parameters is minimized by making a causal connection between physical processes usually treated as independent of each other, which leads to more reliable predictions. However, the strongest points of AMIGA are the following: (1) the inclusion of molecular cooling and metal-poor, population III (Pop III) stars with the most dramatic feedback and (2) accurate follow up of the temperature and volume filling factor of neutral, singly ionized, and doubly ionized regions, taking into account the distinct halo mass functions in those environments. We find the following general results. Massive Pop III stars determine the intergalactic medium metallicity and temperature, and the growth of spheroids and disks is self-regulated by that of massive black holes (MBHs) developed from the remnants of those stars. However, the properties of normal galaxies and active galactic nuclei appear to be quite insensitive to Pop III star properties due to the much higher yield of ordinary stars compared to Pop III stars and the dramatic growth of MBHs when normal galaxies begin to develop, which cause the memory loss of the initial conditions.
