Guest editors’ preface to the special issue devoted to the 2nd International Conference “Numerical Computations: Theory and Algorithms”, June 19–25, 2016, Pizzo Calabro, Italy

This special issue of the Journal of Global Optimization contains twelve high-quality research papers devoted to different aspects of global optimization such as theory, numerical methods and real-life applications. The papers included in this special issue are based on the presentations carefully selected by the guest editors among the talks delivered at the 2nd International Conference “Numerical Computations: Theory and Algorithms (NUMTA)” held in June 19–25, 2016 in Pizzo Calabro, Italy (the first NUMTA conference took place in Falerna, Italy in 2013). The NUMTA 2016 has been organized by the University of Calabria, Rende (CS), Italy, in cooperation with the Society for Industrial and Applied Mathematics, USA. The guest editors actively participated in the organization of the conference: the Program Committee of the NUMTA 2016 was chaired by Yaroslav D. Sergeyev, in their turn, Renato De Leone and Anatoly Zhigljavsky took part in the Program Committee. The goal of the NUMTA 2016 was creation of a multidisciplinary round table for an open discussion on numerical modeling nature by using traditional and emerging computational paradigms. Participants of this conference discussed several aspects of numerical computations and modeling from foundations of mathematics and computer science to advanced numerical techniques. A large part of presentations has been dedicated to optimization. Selected papers presented at the conference in the field of numerical analysis and respective applications have been published in the special issue of the international journal Applied Mathematics and Computation, Volume 318 (2018). In its turn, the present special issue contains articles dealing with global optimization. Let us give a brief description of the papers included in this special issue

Simulation technologies in networking and communications: selecting the best tool for the test

Simulation is a widely used mechanism to validate the theoretical model of networking or communication systems. It is believed that claims made based on simulations are more or less reliable—at least in the sense that something beyond theory is provided. But, how reliable simulation technologies really are is a question asked when the practicality is evaluated with real-world implementation trials. It is a fact that all simulators for the same system do not have the same inherent working method. Different simulators developed for networking and communications technologies have different underlying mechanisms that may significantly affect the simulation scenarios. The same scenario could give different results if different simulators are used for evaluation. Hence, the question “which one is the best for which situation?” is raised. There is no clear verdict on this issue. Therefore, the selection of a particular simulator should be left for the researcher to decide, if that shows relatively better results for his system or model or proposed solution. From this perspective, simulation is considered as something better than nothing to validate a claim or to show something to establish a ground for the proposal. A practical scenario could be, again, very much different and a theoretical model may often be a more solid proof than simulations in the sense that theory would prove the core idea with a solid foundation, and then it would be left for practical testing and performance measurement

Guest editorial : girls' and women's participation in STEM : past lessons and possible futures

Although the presence of women and girls in many Science, Technology, Engineering, and Mathematics (STEM) fields has increased in recent decades, women remain underrepresented in STEM in comparison to men (Watt, 2010). Structures and processes that compromise women and girls’ entry to and advancement in STEM fields (e.g., cultural messages, see Halpern, Benbow, Geary, Gur, Hyde & Gernsbacher, 2007) appear to per sist despite historical evidence of female ability and competence in STEM (OECD, 2015). The current Special Issue 'Girls' and women's participation in STEM: Past lessons and possible futures’, foregrounds the need for vigilance in ensuring equitable STEM opportunities for women and girls, in the light of historical events. However, the Special Issue also reports evidence and approaches that offer forward momentum in addressing inequitable opportunity and promoting futures for women and girls, in a diversity of STEM fields

Preface: World Literature in an Expanding Digital Space

Wikipedia, the world’s largest encyclopedia, and Wikidata, the rapidly growing knowledge graph, are not yet widely used in literary studies, but their scale and multilingualism make them particularly suitable as new means for the study of world literature. This is the hypothesis at the heart of this special issue. Our preface provides a research overview of the topic, briefly summarizes the articles that constitute this issue, and focuses on overarching aspects and common challenges
