Environmental operations strategies: European approaches and research challenges

Since the environment has very recently emerged as a strategic issue, work has only begun to investigate the conceptual linkages between strategic management and the environment. A thoroughly revision of both academic and professional literature evidences that such scarcity of research doubles, or even trebles, when the scenery of the European Operations Management Strategies is considered. The main objective of this paper is, therefore, to discuss the impact of the design of the environmental management strategy on the formulation of the Operations Strategy and its implementation. Since the majority of the literature has neglected to focus the European approaches to such formulation, we will try to overcome this gap by analysing a sample of 2882 European companies

Comprensión de ideas fundamentales de estocásticos en el bachillerato universitario

La presente investigación, de carácter cualitativo, concierne a la comprensión de ideas fundamentales de estocásticos de estudiantes de la Escuela Nacional Preparatoria, donde se imparte la asignatura Estadística y Probabilidad hasta el sexto grado como materia optativa y con carácter teórico, para todas las áreas de orientación vocacional. La investigación, documental en su primera etapa, se refiere al programa de estudios de la asignatura y al principal libro de texto que recomienda. De entre los resultados, la incongruencia entre programa y texto en cuanto a secuencia, el planteamiento en el libro de texto de ejemplos y de ejercicios carentes de referentes, principalmente para la aplicación de “fórmulas”, evidencia en la propuesta institucional la falta de diversidad que compromete el objetivo de la asignatura como introductoria a estocásticos para los estudiantes de todas las áreas

Avoiding core's DUE & SDC via acoustic wave detectors and tailored error containment and recovery

The trend of downsizing transistors and operating voltage scaling has made the processor chip more sensitive against radiation phenomena making soft errors an important challenge. New reliability techniques for handling soft errors in the logic and memories that allow meeting the desired failures-in-time (FIT) target are key to keep harnessing the benefits of Moore's law. The failure to scale the soft error rate caused by particle strikes, may soon limit the total number of cores that one may have running at the same time. This paper proposes a light-weight and scalable architecture to eliminate silent data corruption errors (SDC) and detected unrecoverable errors (DUE) of a core. The architecture uses acoustic wave detectors for error detection. We propose to recover by confining the errors in the cache hierarchy, allowing us to deal with the relatively long detection latencies. Our results show that the proposed mechanism protects the whole core (logic, latches and memory arrays) incurring performance overhead as low as 0.60%. © 2014 IEEE.Peer ReviewedPostprint (author's final draft

Penelope: The NBTI-aware processor

Transistors consist of lower number of atoms with every technology generation. Such atoms may be displaced due to the stress caused by high temperature, frequency and current, leading to failures. NBTI (negative bias temperature instability) is one of the most important sources of failure affecting transistors. NBTI degrades PMOS transistors whenever the voltage at the gate is negative (logic inputPeer ReviewedPostprint (published version

An integrated typology of green manufacturing profiles

This article proposes a typology to classify the Environmental Operations Strategies that the European Companies develop in order to adapt themselves to the requests of their green stakeholders. First, main research lines in Environmental Operations Management are analyzed; second, a typology based on the coherency of different variables that have been considered separately by other authors is presented and validated for a sample of 3051 European manufacturing companies. The results show that European manufacturers have not achieved yet similar levels of integration of the environmental concern into all managerial functions with the aim of reaching a sustainable balance between economic and ecological performance of the firm. Consequently, conventional typologies looking at different environmental criteria in a piecemeal fashion seem to be no longer valid for explanatory and/or decision making purposes
