Hasta finales del siglo XX ha sido incuestionable la vigencia del modelo de internacionalización de empresas conocido como ?Modelo Gradual? o ?Modelo de Uppsala? (Johanson y Vahlne, 1977). Este modelo se caracteriza fundamentalmente por considerar que las empresas comienzan asentándose en sus mercados de origen, en donde van adquiriendo experiencia y conocimiento y van adueñándose de recursos que les permitan internacionalizarse gradualmente en el futuro, comenzando por países cercanos y con similitudes al país de origen. Estas similitudes se miden fundamentalmente en factores demográficos, sociológicos y culturales (Johanson y Vahlne, 1977). Según este modelo, las empresas intentan minimizar al máximo la probabilidad de fracaso de su proceso de internacionalización (Autio y Sapienza, 2000).

La situación económica actual, especialmente en las principales economías desarrolladas de Europa y América, está marcada por los bajos, o incluso negativos, niveles de crecimiento económico de la mayor parte de las naciones, y los elevados niveles de desempleo. Por este motivo, se hace urgente identificar nuevas fórmulas de desarrollo que permitan contribuir al crecimiento económico y a la generación de empleo. El caso español es un claro ejemplo de esta situación. Sus tasas de crecimiento han pasado del 4% en los años 2007-2010, a tasas negativas del 5% en 2009.

Una de los rasgos más característicos de la presente globalización es el desarrollo de la fragmentación de la producción, siendo esta, la división del proceso productivo en diferentes localizaciones a lo largo de varios países. Debido a la globalización de los mercados, al surgimiento de nuevas zonas económicas (Zona Euro, Nafta, Mercosur, etc.), a los países emergentes (China, India, Rusia, Brasil), a la reducción de los costes del transporte internacional y al desarrollo de las comunicaciones, ha provocado el incremento del comercio internacional en bienes intermedios, así como el diseño, fabricación y ensamblaje de un producto en diferentes localizaciones a lo largo de varios países. El incremento de la fragmentación en el comercio internacional ha creado un interés por saber cuales son los factores determinantes de la misma en bienes intermedios. El indicador IITV es el utilizado para medir la fragmentación de la producción entre España y sus 19 principales socios comerciales y varios factores sugeridos por la literatura en fragmentación son utilizados en un rango de años desde el año 2004 al año 2008. Los resultados obtenidos muestran que la gran mayoría del comercio en bienes intermedios es IITV y los factores determinantes de la fragmentación de la producción en el sector del automóvil en España, son el tamaño del mercado, la pertenencia a UE, la distancia y el coeficiente de libre comercio.

En la gestión de los neumáticos de una flota de vehículos el mejor ratio para ello es el coste del neumático dividido por las Horas o Km. realizados por el neumático, pero existen flotas de vehículos que por sus características de uso no se puede realizar un seguimiento de las horas o Km. que realiza el neumático en su vida útil ya que son vehículos que son utilizados por un gran número de conductores en diferentes turnos al día. Este tipo de flotas suelen operar en entornos urbanos y son: Vehículos destinados a la limpieza viaria, recogida de basuras, mantenimiento de jardines, Policía, Guardia Civil, Bomberos etc. así también en menor medida flotas de empresas, renting de vehículos, alquiler de vehículos etc. por ello se propone un modelo de gestión de neumáticos para una flota de vehículos en los que no se puede hacer un seguimiento de las horas o kilómetros realizados por el neumático en su uso.

Although there are many definitions of SME's there is no globally accepted definition of a small or medium-sized enterprise. Small Medium Enterprises (SME) the catalyst in economic growth & development of the country, are facing tough competition in market place and in establishing themselves as credible supplier of quality product and services. In India they are producing more than 8000 different products. The common perception is that small to medium businesses have very little options in terms of CRM solutions. This is clearly not the case. SME's now have a lot of options and can exercise same. Businesses are shifting from product centric to customer centric. Long before the advent of technology, businesses have always recognized that the customer is the soul of every business. Businesses try to have personal relationship with their customers. Moving towards customer centric approach is a multi prolonged efforts that requires transformation of process, culture and strategy from top level to every individual employee. Technology has a crucial role in providing tools and infrastructure to support this. CRM supports SMEs in their business customer loyalty.

Supply chain management works to bring the supplier, the distributor, and the customer into one cohesive process. The Supply Chain Council defined supply chain as ‘Supply Chain: The flow and transformation of raw materials into products from suppliers through production and distribution facilities to the ultimate consumer., and then Sunil Chopra and Meindl, (2001) have define Supply chain management as ‘Supply Chain Management involves the flows between and among stages in a supply chain to maximize total profitability.’ After 1950, supply chain management got a boost with the production and manufacturing sector getting highest attention. The inventory became the responsibility of the marketing, accounting and production areas. Order processing was part of accounting and sales. Supply chain management became one of the most powerful engines of business transformation. It is the one area where operational efficiency can be gained. It reduces organizations costs and enhances customer service. With the liberalization of world trade, globalization, and emergence of the new markets, many organizations have customers and competitions throughout the world, either directly or indirectly. Business communities are aware that global competitiveness is the key to the success of a business. Competitiveness is ability to produce, distribute and provide products and services for the open market in competition with others. The supply chain, a critical link between supplier, producer and customer is emerged now as an essential business process and a strategic lever, potential value contributor a differentiator for the success of any business. Supply chain management is the management of all internal and external processes or functions to satisfy a customer’s order (from raw materials through conversion and manufacture through logistics delivery.). Goods-either in raw form or processed, whole sale or retailed distribution, business or technology services, in everyday life- in the business or household- directly or indirectly supply chain is ubiquitously associated in expanding socio-economic development. Supply chain growth competitive performance and supporting strong growth impulse at micro as well as micro economic levels. Keeping the India vision at the core of the objective, the role of supply chain is to take up social economic challenges, improve competitive advantages, develop strategies, built capabilities, enhance value propositions, adapt right technology, collaborate with stakeholders and deliver environmentally sustainable outcomes with minimum resources.

En el entorno cada vez más dinámico que ha ido configurándose a lo largo del siglo XX en base a las exigencias crecientes del entorno, la necesidad de innovar ha sido una constante. Pero si la productividad fue inicialmente el elemento clave para lograrlo, en el último cuarto de siglo han aparecido nuevos elementos entre los que cabe destacar la calidad, un factor que se ha mostrado cada vez más relevante para la competitividad de la empresa a la par que ha ido adquiriendo un nuevo enfoque multidimensional y dinámico dirigido a proporcionar valor a todos los grupos de interés No hay duda que estas presiones competitivas derivadas de la internacionalización de los mercados que se produce a ritmo creciente durante las últimas décadas del siglo XX, han obligado a muchas organizaciones a implantar los enfoques de la calidad cuando aun no se habían analizado y difundido suficientemente los desajustes y errores derivados de la aplicación de los enfoques tradicionales de organización del trabajo.

Coal is the most plentiful and evenly distributed fossil fuel worldwide. Based on current production, it is estimated that the reserves will last approximately 130 years. Its use worldwide has been increasing, mainly due to consumption by emerging countries. CO2 emissions generated by combustion and the repercussions of such on climate change support the view that it could no longer be used. CO2 capture may be the solution to continue using it, which would cater for the growing energy demand worldwide. The aim of this study is to compare different processes concerning CO2 capture that may be economically viable, ultimately showing that coal, a fossil energy source widely distributed around the world, can, as a result of using different CO2 capture processes, be used as a clean source of electricity. Hence, in places where geological hurdles may render the costs of CO2 storage considerably higher, since it might have to travel far, coal may be used for other purposes, thus valorizing CO2 within the industrial sector. This research is focused on the technical and economic comparison of the most relevant CO2 capture projects designed in Spain using different existing technologies. The oxyfuel project in Ciuden (Leon, Spain), the IGCC Elcogas, precombustion CO2-capture project (Puertollano, Spain) and the postcombustion project in Carboneras (Almeria, Spain) will be analyzed in order to assess the options available to valorizecaptured CO2. Valorizing captured CO2 may be an adequate solution in areas where, although CO2 capture is still possible, storage is not equally so, thus generating a further benefit. The possible uses of CO2 will be assessed in vegetable growing greenhouses, harnessing CO2 in vegetable life cycles. This will also be used in growing algae for subsequent biodiesel production. Both CO2capture and valorizing will eventually lead to the clean use of coal, which will thus enhance the level of self-supply, aiding the development of electric vehicles, which require large amounts of electricity, as well as improve the level of energy autonomy in countries around the world. Another type of fuel, biodiesel, will also be obtained, without this affecting international food prices.

Choosing an appropriate accounting system for manufacturing has always been a challenge for managers. In this article we try to compare three accounting systems designed since 1980 to address problems of traditional accounting system. In the first place we are going to present a short overview on background and definition of three accounting systems: Activity Based costing, Time-Driven Activity Based Costing and Lean Accounting. Comparisons are made based on the three basic roles of information generated by accounting systems: financial reporting, decision making, and operational control and improvement. The analysis in this paper reveals how decisions are made over the value stream in the companies using Lean Accounting while decisions under the ABC Accounting system are taken at individual product level, and finally we will show how TD-ABC covers both product and process levels for decision making. In addition, this paper shows the importance of nonfinancial measures for operational control and improvement under the Lean Accounting and TD-ABC methods whereas ABC relies mostly on financial measures in this context.
