Impact of RFID in reverse logistics

This paper aims to discuss the recent literature on Radio Frequency Identification (RFID) and reverse logistics (RL). Particular attention is applied to the bullwhip effect and its increase as RL activities are integrated into the supply chain. RFID is investigated as a tool to assist with integrating reverse and forward logistics into a seamless supply chain and reduce the bullwhip effect. However, further research is required within this area and in particular the return on investment for RFID-enabled integrated systems.

Implementation challenges of application of radio frequency identification (RFID) in warehouse

Warehouse is an essential component in the supply chain, linking the chain partners and providing them with functions of product storage, inbound and outbound operations along with value-added processes. Allocation of warehouse resources should be efficient and effective to achieve optimum productivity and reduce operational costs. Radio frequency identification (RFID) is a technology capable of providing real-time information about supply chain operations. It has been used by warehousing and logistic enterprises to achieve reduced shrinkage, improved material handling and tracking as well as increased accuracy of data collection. However, both academics and practitioners express concerns about challenges to RFID adoption in the supply chain. This paper provides a comprehensive analysis of the problems encountered in RFID implementation at warehouses, discussing the theoretical and practical adoption barriers and causes of not achieving full potential of the technology. Lack of foreseeable return on investment (ROI) and high costs are the most commonly reported obstacles. Variety of standards and radio wave frequencies are identified as source of concern for decision makers. Inaccurate performance of the RFID within the warehouse environment is examined. Description of integration challenges between warehouse management system and RFID technology is given. The paper discusses the existing solutions to technological, investment and performance RFID adoption barriers. Factors to consider when implementing the RFID technology are given to help alleviate implementation problems. By illustrating the challenges of RFID in the warehouse environment and discussing possible solutions the paper aims to help both academics and practitioners to focus on key areas constituting an obstacle to the technology growth. As more studies will address these challenges, the realisation of RFID benefits for warehouses and supply chain will become a reality.

Oral presentation

David Hume and contractualism

David Hume belonged to the consecuencialist philosophical tendency, in which is included utilitarianism. This tendency was opposed to the normativism philosophy, in which is enrolled contractualism. This article analyzes the critique made by David Hume, from the utilitarianism perspective, against contractualism. The major philosophers of contractualism are Thomas Hobbes, John Locke and Jean Jacques Rousseau. Hume implemented three arguments in opposition to them: 1) historic: the social contract does not have any practical testing. Therefore it could not be presented as the foundation of the state; 2) philosophical: it is not the duty, but the interest that moves men to seek the formation of the political authority; 3) social: in the consciousness of the people, there is no trace of the social contract.Utilitarianism was one of the philosophical tendencies that finished the theoretical hegemony that contractualism had during the XVII and the XVIII centuries. Nonetheless from the historical and social point of view, the liberalization movements in many parts of the world, at that time, were inspired by contractualism. It means that from the theoretical point of view, utilitarianism, certainly, stressed the empirical origins of the state but not the rational justification of the political Authority. Hume was unable to understand the normative force that contractualism owns, which inspires human action.

El dinero fuente de pecados en el Inferno de Dante y en la traducción de Pedro Fernández de Villegas (Burgos, 1515)

El trabajo se centra en el análisis de los pecados relacionados con el dinero en el Inferno de Dante y en la primera traducción castellana de la primera cantiga de la Commedia, obra del arcediano de Burgos Pedro Fernández de Villegas. La traducción, compuesta en coplas de arte mayor y acompañada de un enciclopédico comentario, se publicó en 1515. Particular atención se dedica a la reflexión sobre el problema del mal uso del dinero que Villegas desarrolla en la glosa de los cantos en que con más vigor se levanta la voz de Dante para denunciar la gravedad del pecado de la sed de riquezas. Se analiza la postura del traductor español ante el tema comparándola no sólo con la de Dante sino también con la de Cristoforo Landino, autor del Comento sopra la Comedia, obra exégetica que se publicó por primera vez en Florencia en 1481 y que representó el punto de referencia privilegiado de Villegas.

Proyección y política cultural estadounidense en argentina (1928-1941)

El objetivo del artículo es analizar algunos aspectos de los orígenes de la “política cultural” estadounidense en Argentina. La atención se concentrará en el pasaje desde las declaraciones del presidente Hoover, que contribuyeron a favorecer un clima útil y propicio a la intensificación de los intercambios, a los primeros pasos concretos realizados en el periodo de la presidencia de Roosevelt. Se tratará, en particular, de individualizar las características de la cooperación establecida entre organismos estadounidenses y argentinos para favorecer la proyección cultural estadounidense en el país y el intercambio cultural entre Estados Unidos y Argentina, donde se iba intensificando la difusión de un sentimiento anti-imperialista, y que era entonces objetivo de formas de propaganda particularmente agresivas por parte de los regímenes totalitarios.

"Politica architectonica". El aristotelismo político en el debate político alemán durante la primera edad moderna

Este artículo reconstruye la evolución del debate político alemán durante la primera edad moderna, poniendo atención en particular en la manera en la que tal debate se fue elaborando y transmitiendo dentro de la comunidad de discurso universitaria que lo produjo. El análisis de las características formales y de las modalidades en las que se desarrolló este debate permite demonstrar que el aristotelismo político no fue sólo una doctrina política, sino también, y sobre todo, un código común que más allá de diferencias específicas, caracterizó todas las experiencias universitarias del Sacro Imperio Romano Germánico desde finales del siglo xvi y durante todo el siglo xvii. Las características esenciales de este código se pondrán de relieve en particular a través del caso de los escritos políticos de Iohannes Althusius, en los que la forma y el contenido de su doctrina política terminan coincidiendo.

El valor mitográfico del "Anonymi in Statii Achilleida commentum"

El breve commentum in Statii Achilleida resulta muy interesante para el estudio de la transmisión mitográfica de la Antigüedad tardía al Medievo, pues no sólo participa de las características propias de la mitografía (narraciones de mitos, exégesis racionalista y/o alegórica, interpretaciones etimológicas, anonimato, pseudepigrafía,…), sino que también es otro eslabón en la cadena textual de transmisión, simplificación y canonización de los mitos clásicos.

Green Infrastructure and climate change adaptation

One of the main challenges urban areas, and more particularly the compact ones, are facing is their adaptation to climate change. In recent years, is had been recognized that a more ecosystem approach to spatial planning can play a critical role in meeting these challenges. Green Infrastructure (GI) and its integration in spatial planning emerges as one of the most appropriate and effective ways to improve microclimate and tackle the impacts of climate change and mainly the Urban Heat Island (UHI) effect. This paper initially attempts to clarify the term GI and portrays its benefits and its role as an important spatial planning tool to fulfill different environmental, social and economic needs of urban areas. Then, the paper proceeds to an empirical evaluation of the role of GI in reducing the vulnerability to UHI effect in a compact urban area of the city of Thessaloniki. For this reason, a simple methodology is developed with a twofold purpose: to recognize the risks posed by climate change and especially UHI and to assess the potential offered by available in a compact area GI assets as well as by their redesign in order to maximize their contribution to climate change adaptation.

"Natural" disasters as (neo-liberal) opportunity? Discussing post-hurricane Katrina urban regeneration in New Orleans

By providing a wide literature review, post-hurricane Katrina uneven urban regeneration in New Orleans is presented here by framing it within a historical perspective in order to underline how environmental threats too often seem to be not so much “natural” but rather man-made as well as to highlight both the reasons and the ways in which, in post-disaster reconstruction, competitive growth has been valued over equity, by directly benefiting those who were already the most advantaged. The aim is to highlight how environmental disasters can be considered as socially constructed phenomena, as they cannot be seen as a single event but rather as a process made by a series of progressive steps occurring within different spheres, which do not necessarily concern the environment only.
