Background: The learning process in clinical placements for health care students is a multifaceted endeavor that engages numerous actors and stakeholders, including students, clinical tutors, link teachers, and academic assessors. Successfully navigating this complex process requires the implementation of tasks and mentorships that are synchronized...

Financial literacy has become increasingly crucial in today’s complex financial markets. This paper explores the impact of financial literacy on the stock market by establishing an artificial financial market that aligns with the characteristics of the Chinese A-share market using agent-based modeling. The study incorporates financial literacy into...

En los últimos años, diversos autores han advertido del uso cada vez más extendido de ciertas técnicas de gestión del riesgo por parte de las entidades financieras, argumentando que esto puede provocar una mayor inestabilidad del mercado. Para analizar estas afirmaciones, presentamos un modelo basado en la teoría de juegos evolutivos de un mercado...

Agent‐based modelling has gained recognition in the last years because it provides a natural way to explore the behaviour of social systems. However, agent‐based models usually have a considerable number of parameters that make it computationally prohibitive to explore the complete space of parameter combinations. A promising approach to overcome t...

In the last two decades, the hedge fund sector has experienced a spectacular growth, up to the point that it is currently estimated to move more than 50% of the daily volume of stock markets. In contrast to other financial institutions, hedge funds are subject to less restrictive regulations which, in particular, allow them to sell short. As they e...

The financial system is inherently procyclical, as it amplifies the course of economic cycles, and precisely one of the factors that has been suggested to exacerbate this procyclicality is the Basel regulation on capital requirements. After the recent credit crisis, international regulators have turned their eyes to countercyclical regulation as a...

This is the final report on the VETNET network project that was carried out in the ECER 2018 conference in Bolzano/Bozen. The project was supported by the European Educational Research Association (EERA). The aim of the project was to pilot test the use of ePosters powered by the Learning Toolbox (LTB) as means to present educational research in a...

This paper presents a reflective case study of the introduction of Learning Toolbox as an ePoster solution for conferences. The Learning Toolbox ePoster platform is designed to overcome practical knowledge sharing and communication problems encountered in both the traditional paper poster and standard, screen-based ePoster approaches. Additionally...

The use of agent-based models (ABMs) has increased in the last years to simulate social systems and, in particular, financial markets. ABMs of financial markets are usually validated by checking the ability of the model to reproduce a set of empirical stylised facts. However, other common-sense evidence is available which is often not taken into ac...

The purpose of this research was to test the feasibility of the use of mLearning in the context of nurisng practices. The participants were 10 volunteer nursing students, a link teacher and a nursing practice coordinator of a nursing school in Barcelona.

Background: How can mobile technology support practice-based learning of nursing students in complex health care settings and create a bridge to their formal education? We report on the first stage of an exploratory study at Universitat Gimbernat (Barcelona) involving 10 volunteer students, their tutor, and the department's placement coordinator. S...

Financial institutions around the world use value-at-risk (VaR) models to manage their market risk and calculate their capital requirements under Basel Accords. VaR models, as any other risk management system, are meant to keep financial institutions out of trouble by, among other things, guiding investment decisions within established risk limits...

The overall objective of WP6 is to co-ordinate and synchronize all technology development tasks across the project, as well as providing a base architecture to support this. In Y3, we have addressed this overall goal in the following ways: In T6.2 (Distributed process and platform for Layers software engineering and integration) we have started to...

Purpose: The development of a game based approach to improving the decision-making capabilities of financial traders through attention to improving the regulation of emotions during trading. Design/methodology/approach: The project used a design-based research approach to integrate the contributions of a highly inter-disciplinary team. The approac...

We describe an approach to reducing systematic bias in financial decision-making. We explicitly reject an approach based on the transmission of propositional knowledge. Rather we develop a learning design which is founded in recent research on the role of emotions and their regulation in financial decision-making. We describe a pedagogic approach w...

In the general population, alarming levels exist of financial illiteracy. Many people do not understand financial products very well, and this may have severe consequences for the finances of individual households. Yet, in addition to financial literacy, it may also be that some individuals are more skilled to make financial decisions than others....

Lessons from a European project

Evaluating serious games

Agent-based models have a great potential for the simulation of historical episodes that has to date barely been explored. We focus in particular on the simulation of historical episodes in financial markets, and present here an empirically grounded model of the 1998 turmoil that caused the collapse of the LTCM hedge fund. This model allows us to e...

Questions about methodology and model design are subject to constant debate in the emerging field of agent-based modelling and simulation. This article intends to make progress on some of the more foundational aspects affecting method and design. Our primary focus is on a much neglected area of agent-based modelling, namely that of large-scale, spa...

This article is not about models, but about designing models. Questions about methodology and model design are subject to constant debate in the emerging field of agent‐based modelling and simulation, especially where they pertain to modelling of financial markets. This article intends to make some progress on some of the more practical facets of k...

The trading and investment decision processes in financial markets become ever more dependent on the use of valuation and risk models. In the case of risk management for instance, modelling practice has become quite homogeneous and the question arises as to the effect this has on the price formation process. Furthermore, sophisticated investors who...

There is widespread speculation but little hard evidence that the ever increasing use of financial models establishes a ready channel for contagion and that this can, under adverse circumstances, pose an authentic threat to the stability of financial markets. This article presents a simple simulation exercise that lends support to MacKenzie's thesi...

En los últimos años ha habido un gran número de crisis financieras con graves efectos en la economía de los países afectados. Para evitar o minimizar estos efectos negativos es necesario entender qué factores pueden desencadenar una crisis financiera. Sin embargo, la literatura sólo ofrece explicaciones de tipo cualitativo o modelos analíticos muy...

Recently, some authors have warned of the increasingly widespread use of risk management techniques by financial institutions, arguing that this can cause the market to become more unstable. To analyse these claims, we present a model based on evolutionary game theory of a financial market, where part of the investors use the VaR technique to manag...

This paper sets out to study the impact that market risk limits have on the price dynamics in securities markets. We start out from a standard model in which trading patterns are determined for utility-maximising investors in non-clearing markets with a particularly simple price formation mechanism. To make trading conditions more realistic, we add...

Els mercats financers són un exemple paradigmàtic de sistemes complexos adaptatius. Els paradigmes tradicionals de modelització no permeten reflexar aquesta realitat i hem de recórrer a noves eines. Presentem la simulació basada en sistemes multi-agents com el paradigma idoni per a analitzar els mercats financers en tota la seva complexitat. És un...
