Visualizing and mapping the project management research areas within the International Journal of Project Management: A bibliometric analysis from 1983 to 2018

The Project Management (PM) discipline has remained unchanged over decades, but the practice of this discipline has changed greatly in the last years. Bearing in mind that the PM as become a core activity for organizations and professionals, independently of their area of expertise, it is necessary to develop professional competencies for new project managers. In this way, there are different competency development models, including the ICB 4.0 model of the International Project Management Association (IPMA). Taking this into account, the current research conducts an intellectual and bibliometric analysis of the International Journal of Project Management (IJPM) from 1983 to 2018, in order to know the main research themes and see how these are related to the project management competencies. Finally, it provides a framework to support project managers in the development and direction of future researches identifying emerging, transversal, core and declining themes

The last five years of Big Data Research in Economics, Econometrics and Finance: Identification and conceptual analysis

Today, the Big Data term has a multidimensional approach where five main characteristics stand out: volume, velocity, veracity, value and variety. It has changed from being an emerging theme to a growing research area. In this respect, this study analyses the literature on Big Data in the Economics, Econometrics and Finance field. To do that, 1.034 publications from 2015 to 2019 were evaluated using SciMAT as a bibliometric and network analysis software. SciMAT offers a complete approach of the field and evaluates the most cited and productive authors, countries and subject areas related to Big Data. Lastly, a science map is performed to understand the intellectual structure and the main research lines (themes)

60 years of Business Intelligence: a Bibliometric Review from 1958 to 2017

Business Intelligence (BI) is being seen as a core activity in business, science, education or any field in which the use of intelligent software are vital to achieve their goals. The BI concept is also multidimensional, and it can be defined as a technology-driven process for analyzing data and presenting actionable information to support the organizational decisions. In this respect, the professionals involved in this area of knowledge are seeking to develop a culture of result orientation, focused on an effective decision-making and collaboration. Thus, the main aim of this contribution is to develop a bibliometric analysis to evaluate the performance and conceptual evolution of the authors and publications that are directly related to Business Intelligence

Software Watermarking

Software watermarking is a defence technique used to prevent software piracy by embedding a signature, i.e., an identifier reliably representing the owner, in the code. When an illegal copy is made, the ownership can be claimed by extracting this identifier. The signature has to be hidden inside the program and it has to be difficult for an attacker to detect, tamper or remove it. In this paper we show how the ability of the attacker to identify the signature can be modelled in the framework of abstract interpretation as a completeness property. We view attackers as abstract interpreters that can precisely observe only the properties for which they are complete. In this setting, hiding a signature in the code corresponds to inserting it in terms of a semantic property that can be retrieved only by attackers that are complete for it. Indeed, any abstract interpreter that is not complete for the property specifying the signature cannot detect, tamper or remove it. The goal of this work is to introduce a formal framework for the modelling, at a semantic level, of software watermarking techniques and their quality features

Semifragile Speech Watermarking Based on Least Significant Bit Replacement of Line Spectral Frequencies

There are various techniques for speech watermarking based on modifying the linear prediction coefficients (LPCs); however, the estimated and modified LPCs vary from each other even without attacks. Because line spectral frequency (LSF) has less sensitivity to watermarking than LPC, watermark bits are embedded into the maximum number of LSFs by applying the least significant bit replacement (LSBR) method. To reduce the differences between estimated and modified LPCs, a checking loop is added to minimize the watermark extraction error. Experimental results show that the proposed semifragile speech watermarking method can provide high imperceptibility and that any manipulation of the watermark signal destroys the watermark bits since manipulation changes it to a random stream of bits

Intelligence: origin, evolution and trends (Inteligencia: origen, evolución y tendencias)

In the knowledge economy era, information has become the main asset of organizations, regardless of their typology. In response to this scenario, organizations have opted for the active application of intelligence models based on knowledge of the cultural, social, political, business and technological environment from a holistic, dynamic and flexible point of view. This has favored the emergence of new approaches to Intelligence, which like the more traditional approaches, seek to collect, analyze, interpret and disseminate high value data and information at the right time for use in decision-making processes. However, this does not mean that organizations should assume that more traditional intelligence strategies continue to be viable, on the contrary, the "new rules of the game" are currently being defined and therefore we face completely radical changes. In this sense, it is necessary to review the origins of the concept of intelligence to capture the essence, analyze its evolution and consider trends, with the aim of rethinking and redesigning the concept of Intelligence from an integrative approach, regardless of the nuance or scope of application that our organizations are using. The idea of having a single framework of Intelligence adapted to the reality of the organizations will bring with it a greater diffusion of this discipline and a series of advantages for the organizations themselves. In order to achieve this, a detailed analysis of all existing publications in the literature is proposed through tools specialized in the treatment of large amounts of information. From this analysis, we will obtain the current picture of the concept of intelligence, its main lines of work and research, as well as short/medium term trends
