Hypervisor-Based White Listing of Executables

We describe an efficient system for ensuring code integrity of an operating system (OS), both its own code and application code. The proposed system can protect from an attacker who has full control over the OS kernel. An evaluation of the system's performance suggests the induced overhead is negligible. peerReviewed

Early science learning with a virtual tutor through multimedia explanations and feedback on spoken questions

2018

The purpose of this pilot study with a within-subject design was to gain a deeper understanding about the promise and restrictions of a virtual tutoring system designed to teach science to first grade students in Finland. Participants were 61 students who received six tutoring science sessions of approximately 20 min each. Sessions consisted of a sequence of narrated multimedia science presentations during which a virtual tutor explained science phenomena displayed in pictures. Narrated science explanations were followed by one or more multiple choice questions with immediate feedback about students’ choices and a possible second attempt, during which students reached 97% accuracy. A pretes…

Under the magnifying glass: critical moments in virtual exchange

2022

Virtual Exchange (VE) is a form of experiential learning that relies heavily on learning-by-doing and reflection. The present study draws on visual data comprising students’ perceptions of critical learning incidents presented under an imaginary magnifying glass. To complete this project-closing reflective activity, the students had to describe a critical moment that they had experienced during VE and present it in a visual form. Data was collected longitudinally, in three projects (2019, 2020, and 2021) that followed the same pedagogical design and focused on the theme of tourism. The collaborating universities were from three countries: Poland, Finland, and the Netherlands. We used the me…

In search for the conceptual origin of university students' community in a confluence of on- and offline learning environments ethnographies in techn…

2007

Contemporary society requires its citizens to develop capacities to resituate their activities in collective unities and to successfully communicate their actions within these multiple local and global communities. Also in higher education, educational practices are increasingly fixed around web-based, collaborative learning environments, designed for the values of community and collective learning. The publication presents a study that explored learning communities in technology-rich higher education milieus. The aim was to search for the conceptual origin of university students’ community and its reference point in this context. In this work, methodological tools to study, to analyse, and…

“I felt a bit nervous” : Virtual Exchange as an emotional journey

2021

Virtual Exchange is a collective term for a set of collaborative online learning practices that cut across institutional, cultural, and international borders. Moving outside their learning environments, the participants engage in project work with foreign peers. The teams have to work across time zones, use foreign languages, manage cultural differences and apply digital tools for communication and collaboration. The virtual projects enhance the development of transversal work/life skills, which are an asset in today’s global labour market. The aim of the present study is to explore the emotional trajectory of Virtual Exchange based on the students’ e-portfolios. By analysing the self-evalu…

Cómo crear una actividad H5P de ordenar los párrafos en el Aula Virtual

2022

En este videotutorial se muestra cómo crear una actividad H5P de ordenar los párrafos en el Aula Virtual (Moodle 3.11). Este trabajo forma parte del Proyecto de Innovación Docente Multimedia learning objects in moodle: Sustainable Development Goals (Ref: UV-SFPIE_PID-1640789) financiado por el Vicerrectorado de Ocupación y Programas Formativos de la Universitat de València en el curso académico 2021/2022.

Rethinking virtuality in a digital media age

2017

Scholars have studied virtuality in teams and organizations for over two decades. The term “virtual” is of- ten used loosely and imprecisely, and theoretical debates have flourished over what differentiates virtual from non-virtual teams. In these debates, scholarship has not explicitly considered the significant ways in which the technological landscape has changed over this time. While the virtual is often treated as a separate space from “real”, physical or face-to-face interaction, the increasing technological saturation of our lives has resulted in a blurring of online and offline worlds such that these distinctions may no longer hold up. I will explore whether the term “virtuality” st…

STATBOX Concept for Simulation of Urban Phenomena

2013

Abstract An urban environment is a dynamic system which is constantly changing in terms of space and time. There are two dimensions in any urban environment – the physical dimension and the functional dimension. All of the structures of an urban environment interact and people are the intermediaries in this process. The spatial structure of cities has been studied from various perspectives by architects, urban planners, environmental scientists, economists, geographers etc. Constant monitoring that is based on remote sensing, spatial statistics, simulation etc., is needed to make on going note of transformation in the various types of land use that exist, movement of people and business env…
