Conflictive Touring
2015
Problems to understand social phenomenon associates to our misconceptions, stereotypes and prejudices imposed during our early socialization. This happens not only with tourism which is valorized as a right of all citizens in modern societies, but also with terrorism, judged as the main threat of West. However, what would happen if both would be different sides of the same coin? This essay review explores the roots of tourism and terrorism during the process of unionization in US. What on one hand resulted in a hyper-mobile process that shore up tourism, on another was a desesperate attempt to struggle against terrorism. In this vein, it is safe to say that tourism is terrorism by other mea…

Survival analysis of author keywords: An application to the library and information sciences area
2020
[EN] Our purpose is to adapt a statistical method for the analysis of discrete numerical series to the keywords appearing in scientific articles of a given area. As an example, we apply our methodological approach to the study of the keywords in the Library and Information Sciences (LIS) area. Our objective is to detect the new author keywords that appear in a fixed knowledge area in the period of 1 year in order to quantify the probabilities of survival for 10 years as a function of the impact of the journals where they appeared. Many of the new keywords appearing in the LIS field are ephemeral. Actually, more than half are never used again. In general, the terms most commonly used in the …
Decoding the XXI Century’s Marketing Shift: An Agency Theory Framework
2016
Since the beginning of the XXI century, marketing theory has moved through a series of epistemological shifts from modern positivism to postmodern constructivism. This has resulted in a series of changes to the main concepts of “traditional” marketing such as: market, product, customer, and value. These shifts can be better viewed under a social cybernetics approach such as agency theory. This is because there is now a view that the linear concept of value creation needs to give way to the more complex process of value cocreation, where value is created collectively. Agency theory is one approach that is able to shed light on how customers and providers are able to recursively create collec…

Terrorists Tend to Target Innocent Tourists
2015
Over last decades, policy makers in tourism and hospitality acknowledged that terrorism was the worse threat to tourism and West because of many reasons. Terrorism not only affects seriously economies generating unemployment and stagnation in international demand, but also triggers an escalation of violence where all advertisement efforts are backfired. Nevertheless, this essay review explores the historical roots of modern tourism and worker unions to see the point of connection between both. What beyond the boundaries of society is called terrorist attack, inside is named “strike”. This review reminds that the origin of terrorism has been coined in West, as a result of capitalism expansio…
Aligning Two Specifications for Controlling Information Security
2014
Assuring information security is a necessity in modern organizations. Many recommendations for information security management exist, which can be used to define a baseline of information security requirements. ISO/ IEC 27001 prescribes a process for an information security management system, and guidance to implement security controls is provided in ISO/IEC 27002. Finnish National Security Auditing Criteria (KATAKRI) has been developed by the national authorities in Finland as a tool to verify maturity of information security practices. KATAKRI defines both security control objectives and security controls to meet an objective. Here the authors compare and align these two specifications in…
Performance and energy optimisation in CPUs through fuzzy knowledge representation
2019
Abstract This paper presents an automatic design space exploration using processor design knowledge for the multi-objective optimisation of a superscalar microarchitecture enhanced with selective load value prediction (SLVP). We introduced new important SLVP parameters and determined their influence regarding performance, energy consumption, and thermal dissipation. We significantly enlarged initial processor design knowledge expressed through fuzzy rules and we analysed its role in the process of automatic design space exploration. The proposed fuzzy rules improve the diversity and quality of solutions, and the convergence speed of the design space exploration process. Experiments show tha…
An overview of incremental feature extraction methods based on linear subspaces
2018
Abstract With the massive explosion of machine learning in our day-to-day life, incremental and adaptive learning has become a major topic, crucial to keep up-to-date and improve classification models and their corresponding feature extraction processes. This paper presents a categorized overview of incremental feature extraction based on linear subspace methods which aim at incorporating new information to the already acquired knowledge without accessing previous data. Specifically, this paper focuses on those linear dimensionality reduction methods with orthogonal matrix constraints based on global loss function, due to the extensive use of their batch approaches versus other linear alter…
