Learning about Dynamic Problems with Computer Simulators: A Case of System Dynamics Simulation Models

2008

A vast body of research shows that people by and large fail to understand and manage dynamic environments. Given the increasing complexity of our world, there is an urgent need to develop more effective ways to present dynamic problems. Many studies propose computer simulators as virtual learning environments to help people understand and manage complex problems. Still, experimental data show that simulators often carry problems from reality into the virtual laboratory. An analysis from the perspective of cognitive load theory suggests that learning about complex problems could be improved by enhancing descriptions with simulation elements that would facilitate interactive exploration of th…

From the Museum to the site and backwards

2021

Digital archaeological reconstructions usually at documenting the original position of blocks and architectural elements of the building, both the ones on site and those exhibited in museums. Digital survey and representation provide the opportunity to place the fragments into the reconstruction model of the building, thus making the understanding of their shape and function much easier. A relevant difference between past and present reconstructions is the representation of the context and the landscape. The context is a relevant feature of watercolor ‘Restorations’ of the Grand Tour; on the other hand, in digital reconstructions the landscape is often neglected or reduced to a ‘background’…

Virtual Reality in Marketing: A Framework, Review, and Research Agenda

2019

[EN] Marketing scholars and practitioners are showing increasing interest in Extended Reality (XR) technologies (XRs), such as virtual reality (VR), augmented reality (AR), and mixed reality (MR), as very promising technological tools for producing satisfactory consumer experiences that mirror those experienced in physical stores. However, most of the studies published to date lack a certain measure of methodological rigor in their characterization of XR technologies and in the assessment techniques used to characterize the consumer experience, which limits the generalization of the results. We argue that it is necessary to define a rigorous methodological framework for the use of XRs in ma…

Decision Making and Cognitive Behavioral Flexibility in a OCD Sample: a Study in a Virtual Environment

2015

Neuropsychological disorders are common in Obsessive-Compulsive Disorder (OCD) patients. Executive functions, verbal fluency and verbal memory, shifting attention from one aspect of stimuli to others, mental flexibility, engaging in executive planning and decision making, are the most involved cognitive domains. We focus on two aspects of neuropsychological function: decision making and cognitive behavioral flexibility, assessed through a virtual version of the Multiple Errand Test (V-MET), developed using the NeuroVR software.Thirty OCD patients were compared with thirty matched control subjects. The results showed the presence of difficulties in OCD patients with tasks where the goal is n…

Speculation and lottery-like demand in cryptocurrency markets

2021

Abstract This is the first paper that explores lottery-like demand in cryptocurrency markets. Since recent research provides evidence that cryptocurrency returns appear to be short-memory processes, we modify Bali, Cakici and Whitelaw’s (2011) and Bali, Brown, Murray, and Tang’s (2017) MAX measure and employ a weekly forecast horizon and daily log-returns from the previous week to calculate the metric for our portfolio sorts. From an econometric point of view, this study proposes statistical tests that are robust to unknown dynamic dependency structures in the cryptocurrency data. Our results show that average raw and risk-adjusted return differences between cryptocurrencies in the lowest a…

Creación, gestión y puesta en marcha de entornos virtuales de aprendizaje en Formación Profesional

2018

Nuestra aportación se inserta en un planteamiento de Educación Inclusiva que pretende facilitar la construcción del conocimiento del alumnado en Formación Profesional. Se concreta en un Proyecto de aula para crear, gestionar y poner en marcha dos empresas virtuales, de las cuales cada uno de los alumnos/as es socio partícipe y trabajador/a al mismo tiempo; así como la selección de sus formas jurídicas justificando su elección a través del análisis comparativo explicitando ventajas e inconvenientes de cada una de las formas jurídicas; trámites de constitución y su lanzamiento al mercado de forma simulada diseñando los organigramas en soporte digital de cada una de las empresas y creando sus …

Bhaskar’s Theory of Publishing and Its Contribution to Theorizing (Evolving New Forms of) Educational Media

2021

Enterprises which are usually categorized as educational publishers increasingly develop and market products like learning platforms. Such products are at least to a considerable extent pieces of software rather than products based on content in the sense of texts, images, and maybe moving images or sounds (which typically constitute products of the media industries). Michael Bhaskar’s The Content Machine. Towards a Theory of Publishing (2013) represents one of the most comprehensive theoretical approaches to publishing in recent years. This contribution discusses, how far products like learning platforms can be described as results of acts of (educational) publishing or can be considered (…

Dispersion Interactions between Neutral Atoms and the Quantum Electrodynamical Vacuum

2018

Dispersion interactions are long-range interactions between neutral ground-state atoms or molecules, or polarizable bodies in general, due to their common interaction with the quantum electromagnetic field. They arise from the exchange of virtual photons between the atoms, and, in the case of three or more atoms, are not additive. In this review, after having introduced the relevant coupling schemes and effective Hamiltonians, as well as properties of the vacuum fluctuations, we~outline the main properties of dispersion interactions, both in the nonretarded (van der Waals) and retarded (Casimir--Polder) regime. We then discuss their deep relation with the existence of the vacuum fluctuation…
