The Light Side of Passwords : Turning Motivation from the Extrinsic to the Intrinsic
2019
There are many good and bad aspects to password authentication. They are mostly without cost, securing many accounts and systems, and allowing users access from anywhere in the world. However, passwords can elicit dark side phenomena, including security technostress; with many users feeling negatively towards them, as they struggle to cope with the sheer numbers required in their everyday lives. Much research has attempted to understand users’ interactions with passwords, examining the trade-off between security, memorability, user convenience, and suggesting techniques to manage them better. However, users continue to struggle. Many studies have shown that users are more concerned with goa…
Characterisation of the Degree of Musical Non-Markovianity
2022
As an aid for musical analysis, in computational musicology mathematical andinformatics tools have been developed to characterise quantitatively some aspectsof musical compositions. A musical composition can be attributed by ear a certainamount of memory. These results are associated with repetitions and similarities ofthe patterns in musical scores. To higher variations, a lower amount of memory isperceived. However, the musical memory of a score has never been quantitativelydefined. Here we aim to give such a measure following an approach similar tothat used in physics to quantify the memory (non-Markovianity) of open quantumsystems. We apply this measure to some existing musical composit…

Running a hybrid: mingling in-service and pre-service teachers in peer-mentoring groups
2020
his study examines a hybrid form of the Finnish Peer-Group Mentoring (PGM) merging student teachers and in-service teachers of different career stages in group meetings facilitated by an educated mentor. Experiences of the in-service participants were studied by interviewing them, and the data were analysed through thematic analysis. Four main themes were identified: 1) Enjoying group activities, 2) Personal professional development, 3) Attaching to the professional community and 4) Developing the teacher profession. The study shows that the hybrid model of peer-group mentoring enables opportunities for teacher learning that benefit both schools and teacher education institutions. peerRevie…
Hyperstoichiometric interaction between silver and mercury at the nanoscale.
2012
Breaking through the stoichiometry barrier: As the diameter of silver particles is decreased below a critical size of 32?nm, the molar ratio of aqueous HgII to Ag0 drastically increases beyond the conventional Hg/Ag ratio of 0.5:1, leading to hyperstoichiometry with a maximum ratio of 1.125:1 (see figure). Therein, around 99?% of the initial silver is retained to rapidly form a solid amalgam with reduced mercury.
Merit, Competition, Distinction
2018
The article presents a critique of competition by introducing a concept called 'distinction'. Competition is thought to work as a guarantee of the fairness of meritocratic procedures (merit-based recruiting in the job market or e.g. entrance examinations). However, fairness created by competition is, even at its best, only relative. This critique is then used a part of a larger critique of the role of merit in society.
Exploring students’ metacognition in relation to an integral-area evaluation task
2021
Several studies have been conducted to explore students’ understanding of the integral-area relationships, however, only a few focused on students’ metacognition in relation to this topic. In this study, students’ metacognitive knowledge, skills, and experiences in relation to an integral-area evaluation task are explored using semi-structured interviews and think-aloud protocol. The results show that several students developed monitoring strategies in relation to integral-area relationships; however, they do not use these strategies when solving integral-area tasks. The findings suggest that teachers and lecturers could use monitoring strategies more often when solving mathematical questio…
On automatic algorithm configuration of vehicle routing problem solvers
2019
Many of the algorithms for solving vehicle routing problems expose parameters that strongly influence the quality of obtained solutions and the performance of the algorithm. Finding good values for these parameters is a tedious task that requires experimentation and experience. Therefore, methods that automate the process of algorithm configuration have received growing attention. In this paper, we present a comprehensive study to critically evaluate and compare the capabilities and suitability of seven state-of-the-art methods in configuring vehicle routing metaheuristics. The configuration target is the solution quality of eight metaheuristics solving two vehicle routing problem variants.…
A Cost-Effective Solution for Clearing High-Impedance Ground Faults in Overhead Low-Voltage Lines
2019
Downed distribution conductors in overhead distribution systems may not be a concern for equipment but greatly challenge the safety of persons, as well as the integrity of properties. Standard overcurrent protective devices may not be able to detect the magnitudes of currents resulting from high-impedance ground faults. Sophisticated relays able to detect high-impedance ground faults have been available to electric utilities. However, their implementation is rather uncommon, especially in developing countries, most likely due to their costs. In this paper, the authors formalize the problem, and propose a possible cost-effective solution for low-voltage overhead lines with neutral wire. This…
Mappings of finite distortion between metric measure spaces
2015
We establish the basic analytic properties of mappings of finite distortion between proper Ahlfors regular metric measure spaces that support a ( 1 , 1 ) (1,1) -Poincaré inequality. As applications, we prove that under certain integrability assumption for the distortion function, the branch set of a mapping of finite distortion between generalized n n -manifolds of type A A has zero Hausdorff n n -measure.
