“Te das cuenta de que el mundo puede ser tan distinto y similar al mismo tiempo”: Telecolaboración y desarrollo de la competencia intercultural en la…

2016

Este artículo versa sobre la integración de la telecolaboración, o intercambio intercultural en línea, en contextos de educación superior, para el desarrollo de la competencia intercultural en el aula inglés como lengua extranjera. Se analiza, desde la perspectiva de los estudiantes, un intercambio de telecolaboración en que participantes de España y de Estados Unidos colaboraron en grupos interculturales y plurinacionales para llevar a cabo una serie de tareas cuya complejidad cognitiva iba progresivamente en aumento: creación de un perfil digital, grabación de un vídeo de presentación, interacción multimodal (texto, audio, videoconferencia) para discutir y debatir los diferentes temas pro…

Interactions of pharmaceutical companies with world countries, cancers and rare diseases from Wikipedia network analysis

2019

AbstractUsing the English Wikipedia network of more than 5 million articles we analyze interactions and interlinks between the 34 largest pharmaceutical companies, 195 world countries, 47 rare renal diseases and 37 types of cancer. The recently developed algorithm using a reduced Google matrix (REGOMAX) allows us to take account both of direct Markov transitions between these articles and also of indirect transitions generated by the pathways between them via the global Wikipedia network. This approach therefore provides a compact description of interactions between these articles that allows us to determine the friendship networks between them, as well as the PageRank sensitivity of countr…

Cooperative Inventory control

2005

In multi-retailer inventory control the possibility of sharing setup costs motivates communication and coordination among the retailers. We solve the problem of finding suboptimal distributed reordering policies that minimize setup, ordering, storage, and shortage costs incurred by the retailers over a finite horizon. Neuro-dynamic programming (NDP) reduces the computational complexity of the solution algorithm from exponential to polynomial on the number of retailers.

Vectofocimetry: Dioptric power measurement in manual focimeters using power vectors

2021

Abstract Dioptric power measurement is classically achieved using manual focimeters. In this contribution, we present vectofocimetry as a novel methodology to be easily implemented in manual focimeters for improving their capabilities regarding dioptric power measurement. The new procedure is conceptually based on power vector formalism of dioptric power which represents the dioptric power as three values in the form of [M, J0, J45], it uses an iterative process of blur reduction, and it only requires a few modifications in the device that are easy-to-adapt and cost-effective. As a result, dioptric power measurements are easily and quickly obtained with comparable results to the reported on…

Solving NP-Complete Problems with Networks of Evolutionary Processors

2001

We propose a computational device based on evolutionary rules and communication within a network, similar to that introduced in [4], called network of evolutionary processors. An NP-complete problem is solved by networks of evolutionary processors of linear size in linear time. Some furher directions of research are finally discussed.

Using methods and IT tools innovatively for the management of International IS development projects

2008

Increasingly, information systems (IS) development is done internationally. International IS development is very complex. Some of the factors that lead to this high complexity include geographically dispersed teams, time-zone differences, cultural differences, language problem, and communication challenges. All these affect coordination and collaboration significantly. Therefore, the project management activities have to be executed via different methods and information technology (IT) tools. There is a significant lack of studies dealing with the management of international IS development using methods and IT tools innovatively. Therefore, this study has been undertaken to fill in this res…

Management Challenges in the Context of a Complex View - SMEs Perspective

2015

Abstract The complexity significantly affects the functioning and development of enterprises and is important in understanding the activities of an organization. The perspective of complexity makes the decisions bringing with them a growing economic risk. One group particularly sensitive to the complexity in internal and external environment are small and medium-sized enterprises. Despite this increasing importance, most SMEs have not introduced or implemented yet a complexity management system/approach or they do not realize of the multitude of management challenges emerging with the phenomenon of complexity. The role of SMEs in each economy encourages to explore this area in order to deve…

Introduction to the JOTSC Special Issue on Leveraging Organizational Change and Knowledge Management to Address Environmental Complexity

2016

Claims that organizations are living through a period of unprecedented complexity are not new. Accordingly, scholars and practitioners are recognizing the challenges that originate from operating in increasingly complex and interconnected environments. Despite the relevant theoretical advances occurred in organizational and management studies as a consequence of such recognition, a full appreciation of how organizations deal with complex situations is still missing (Amagoh, 2008; Axeldrod & Cohen, 2000). Accordingly, this special issue aims to contribute to elucidate how organizations respond to environmental complexity through the activation of specific processes of organizational change a…
