Hypervisor-Based White Listing of Executables
2019
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
Towards an understanding of big data analytics as a weapon for competitive performance
2017
Master's thesis Information Systems IS501 - University of Agder 2017 Context: Big data has in the recent years been an area of interest among innovative organizations and has started to become a major priority for organizations in general, either through their own big data departments or by purchasing big data analyses from suppliers. Big data analytics means more knowledge from more data sources and is by many prophesied to be a contributing source of big change in how organizations receive their intelligence. Purpose: This thesis investigates the connection between big data and competitive performance. This connection could be explained through the following two paths; 1) how big data ana…
Operating leverage and the cost of debt in European agri-food firms
2020
Aim of study: To analyse the effect that operating leverage exerts on the cost of debt of agri-food firms in Europe, both in isolation and indirectly through its other risk factors.Area of study: We used panel data made up of 18,360 European firms from 2009 to 2016 (146,880 observations).Material and methods: The data were extracted from the ORBIS database and EUROSTAT. The econometric approach was estimated by the Generalized Method of Moments.Main results: The results obtained confirm that operating leverage or cost structure, in addition to affecting the cost of debt, also affects the relationship between that cost and other sources of risk. More specifically, indebtedness, size, specifi…
Estimating Programming Exercise Difficulty using Performance Factors Analysis
2020
This Work in Progress Paper studies student and exercise modelling based on pass/fail log data gathered from an introductory programming course. Contemporary education capitalizes on the communications technology and remote study. This can create distance between the teacher and students and the resulting lack of awareness of the difficulties students encounter can lead to low student satisfaction, dropout and poor grades. In many cases, various technological solutions are used to collect individual exercise submissions, but there are little resources for indexing or modelling the exercises in depth. Exercise specific feedback from students may not be easily obtainable either. In the presen…
Lifelong physical activity and long-term labor market outcomes
2018
This thesis examines the longitudinal associations between leisure-time physical activity, educational attainment, and labor market outcomes. Data are drawn from the ongoing longitudinal Cardiovascular Risk in Young Finns Study, which is combined with register-based data from Statistics Finland. The thesis consists of four empirical studies organized in separate chapters. The study chapters are preceded by an introductory chapter presenting the background literature and an overview of the thesis, including the research questions, data, and main results. Chapter 2 analyzes the role of childhood physical activity in academic achievement and subsequent educational attainment. We find that phys…
Motivational sources of practical nursing students at risk of dropping out from vocational education and training
2019
The aim of this study was to contribute to the understanding of the reasons for low or high academic motivation among practical nursing students at risk of dropping out from vocational education and training. The research data consisted of semi-structured interviews with 14 Finnish students, which were analysed by qualitative content analysis. The analysis identified six motivational sources. Two of these sources – Responsible agency and Completing out of necessity – were related to engagement in studying, whereas two other sources – Exhaustion from learning challenges and Tight-roping between competing responsibilities – were related to disengagement from studying. Emotional drive and Soci…
What do we do when we analyse the temporal aspects of computer-supported collaborative learning? A systematic literature review
2021
To better understand the premises for successful computer-supported collaborative learning (CSCL), several studies over the last 10 years have analysed the temporal aspects of CSCL. We broadly define the temporal aspects of CSCL as focusing on the characteristics of or interrelations between events over time. The analysis of these aspects, however, has been loosely defined, creating challenges regarding the comparability and commensurability of studies. To address these challenges, we conducted a systematic literature review to define the temporal analysis procedure for CSCL using 78 journal papers published from 2003 to 2019. After identifying the key operations to be included in the proce…
Student agency analytics: learning analytics as a tool for analysing student agency in higher education
2020
This paper presents a novel approach and a method of learning analytics to study student agency in higher education. Agency is a concept that holistically depicts important constituents of intentional, purposeful, and meaningful learning. Within workplace learning research, agency is seen at the core of expertise. However, in the higher education field, agency is an empirically less studied phenomenon with also lacking coherent conceptual base. Furthermore, tools for students and teachers need to be developed to support learners in their agency construction. We study student agency as a multidimensional phenomenon centring on student-experienced resources of their agency. We call the analyt…
