Virtual Enterprise Simulation Game as an Environment for Collaborative Creativity and Learning
2021
AbstractWhen employees become accustomed to everyday working habits it can prevent them from generating creative ideas. This familiarity takes the forms of mainly collaborating with familiar colleagues, playing roles that develop over years, and solving encountered problems with proven strategies. This chapter considers how a virtual enterprise simulation game (RealGame) can potentially foster digital creativity and collaborative learning. The game simulates a situation where team members take responsibility for managing a virtual manufacturing company and its supply chain. Theoretically, we consider RealGame a facilitating environment for people to collaborate by offering a safe environmen…

A Participant Experience Method for Illustrating Individuals’ Experiences in the Course of an Evolving Virtual Learning Community
2003
Early definitions of virtual learning communities often abstracted participants from their offline environments. However, often students’ virtual and physical environments are not essentially separated. Likewise, scholars should become more sensitive to and aware of their research principles and practices guiding studies in virtual settings and especially, in the intersections of on- and offline contexts. The participant experience method discussed in this paper, grants access also to the events outside the virtual learning context connecting various social settings and simultaneous events. However, the use of participant experience methods requires critical reflection during its various ph…
Fostering entrepreneurial learning processes through Dynamic Start-up business model simulators
2018
Abstract Entrepreneurial learning is a critical process in realizing the success or failure of a new business venture, as it implies that would-be entrepreneurs acquire those strategic management competencies required to start and manage a new business. Actually, statistics on start-up survival/failure rate reveal that the main reasons for failure are related to a lack of entrepreneurial competencies of start-uppers. This paper argues that combining Business Model representation schemas with System Dynamics modelling may support potential start-up entrepreneurs in learning and experimenting how to turn a business idea into a real firm. System Dynamics modelling is a methodology that allows …
Software and Standards in an Emerging Domain
2010
This paper considers the software market in the field of e-Learning and Technology Enhanced Learning (TEL) through observing standardization developments in the domain. A model of software market evolution suggests that observations on development and deployment of standards in the domain indicate the status on the market. As the model holds, in a mature phase, level of standardization is high and the number of competing standards low. The result of the study is, there appears to be a market, but a heterogeneous one, with hesitation on dominant designs and an overall modest level of standards adoption. Content standardization enables the (re)use of the learning content in multiple formats w…
Employee shirking and overworking: modelling the unintended consequences of work organisation
2020
Underworking (i.e. shirking) and overworking of employees can have detrimental effects for the individual and the organisation. We develop a computational model to investigate how work structure, specifically the way in which managers distribute work tasks amongst employees, impacts work intensity and working time. The model draws on theories from economics, psychology and management, and on empirical observations. The simulations show that when managers correctly estimate task difficulty, but undervalue the employee’s competence, opportunities for shirking are provided due to longer deadlines. Similarly, if managers overvalue the employee’s competence, they set tighter deadlines leading to…
Knowledge-driven multi-agent simulation engineering for assessing the effectiveness of disaster management plans
2020
Protecting humans from disasters has been an active mission of governments and experts through the definition of disaster management plans. Defining disaster response strategies is crucial in order to reduce the number of victims and the economic impact. In order to select which response plan is best suited to a specific disaster situation, these plans must be evaluated. However, such evaluation is limited by the high cost of exercises and the specificity of existing simulation models. The approach defended in this thesis combines techniques from Semantic Web and multi-agent simulation to evaluate disaster management response plans. It is composed of four steps : (1) modeling disaster manag…
Invariant rotational curves in Sitnikov's Problem
1993
The Sitnikov's Problem is a Restricted Three-Body Problem of Celestial Mechanics depending on a parameter, the eccentricity,e. The Hamiltonian,H(z, v, t, e), does not depend ont ife=0 and we have an integrable system; ife is small the KAM Theory proves the existence of invariant rotational curves, IRC. For larger eccentricities, we show that there exist two complementary sequences of intervals of values ofe that accumulate to the maximum admissible value of the eccentricity, 1, and such that, for one of the sequences IRC around a fixed point persist. Moreover, they shrink to the planez=0 ase tends to 1.
Large eddy simulation of inertial particles dispersion in a turbulent gas-particle channel flow bounded by rough walls
2020
The purpose of this paper is to understand the capability and consistency of large eddy simulation (LES) in Eulerian–Lagrangian studies aimed at predicting inertial particle dispersion in turbulent wall-bounded flows, in the absence of ad hoc closure models in the Lagrangian equations of particle motion. The degree of improvement granted by LES models is object of debate, in terms of both accurate prediction of particle accumulation and local particle segregation; therefore, we assessed the accuracy in the prediction of the particle velocity statistics by comparison against direct numerical simulation (DNS) of a finer computational mesh, under both one-way and two-way coupling regimes. We p…
Theoretical prediction of rainfall intensity for a small rainfall simulator
2022
In this contribution, a theoretical approach was developed for predicting rainfall intensity for a small rainfall simulator. The developed equation was tested for two different devices and different pressure head and water temperature values. The proposed relationship was found to have a good predictive ability of rainfall intensity. The proposed theoretical approach could be usable with other devices that operate on the same principles of the simulator considered in this investigation.
