Agents of responsibility in software vulnerability processes

Modern software is infested with flaws having information security aspects. Pervasive computing has made us and our society vulnerable. However, software developers do not fully comprehend what is at stake when faulty software is produced and flaws causing security vulnerabilites are discovered. To address this problem, the main actors involved with software vulnerability processes and the relevant roles inside these groups are identified. This categorisation is illustrated through a fictional case study, which is scrutinised in the light of ethical codes of professional software engineers and common principles of responsibility attribution. The focus of our analysis is on the acute handling of discovered vulnerabilities in software, including reporting, correcting and disclosing these vulnerabilities. We recognise a need for guidelines and mechanisms to facilitate further improvement in resolving processes leading to and in handling software vulnerabilities. In the spirit of disclosive ethics we call for further studies of the complex issues involved.     

Analysis of anticipation by 3D motion capturing – a new method presented in karate kumite

Anticipation is an important performance factor in karate kumite. A new approach analysing anticipation in realistic combat situations by motion capturing with a high temporal resolution is presented. The advantage of this approach is that both karate athletes interacting sports specific can be recorded synchronously; thus, the presented method has the potential to analyse visual information pickup due to coordination pattern of interaction between real athletes. The aim is to demonstrate the usability of the current method for anticipation research and to investigate if the distance between two athletes and their attacking technique play a role in the reaction of the defending athlete. Furthermore, relevant cues lying within each attacking technique and little individual differences are shown. Four male karate athletes took part in this study. Logistic regression indicated that both factors (distance × attacking technique) play a significant role in reaction. However, a correlation between these factors shows that only the attacking technique is a good predictor for reaction. Results show that the attacking technique jabbing punch (jap. Kizami-Zuki) was easier to anticipate than the attacking techniques reverse punch (jap. Gyaku-Zuki) and the round kick (jap. Mawashi-Geri).     

Bildung and educational action research: resources for hope in neoliberal times

This paper draws upon empirical research to provide insights into current teacher learning practices under broader neoliberal conditions, and how the latter might be resisted. The paper contrasts neoliberal approaches to teachers’ learning with the Nordic tradition of educational action research and ‘Bildung’ as alternative resources to guide teachers’ and principals’ collective learning practices in schools, and draws upon empirical research to provide evidence of the benefits and challenges of doing so. The paper draws upon research into the learning practices of primary teachers in Australia, early childhood teachers in Sweden, and principals in Finland. The research reveals the influence of more Bildung-informed conceptions of educational action research, even as these are challenged by existing administrative cultures, and neoliberal pressures. The research presents ‘resources for hope’ to promote collective learning based on democratic values, not in an idealized or abstract manner, but in a way which is simultaneously cognizant of empirical realities.     

Team teaching implementation in engineering education: teacher perceptions and experiences

ABSTRACT

In 2014, Metropolia University of Applied Sciences implemented a fundamental change in its curriculum from small single topic 3–5 credits courses into 15 credits multidisciplinary courses implemented by teacher teams. This paper focuses on how teachers of Information Technology programs experienced the reform. Research data include teacher feedback and opinions that were collected during training sessions and interviews. Team teaching is a substantial change for teachers that raises concerns about time management, getting enough compensation for the work and possible loss of teacher autonomy. However, teacher teams that managed to overcome these challenges saw a variety of benefits in the new approach. Not only was team teaching seen as a means for providing students with the skills they need, but it also was discovered as a way to enhance the teacher’s own professional development.     

Conceptualizing and Measuring the Social Uses of the Internet: The Case of Personal Web Sites

The researchers working on information society measures have recently started to consider how people use the Internet not only as a tool but also as a platform for social relations. As the ultimate objective of information society measures is to provide reliable guidelines for social policy, finding criteria for separating “positive” uses of Internet from “negative” ones is an important task. This article employs the concepts of communicative and strategic action as defined by Habermas for that purpose. A general conceptual typology of three communicative and three strategic social uses of Internet is offered, which can be applied to measure uses of any of the Internet's interactive services. A specific empirical application to social uses of personal web sites demonstrates that the deduced measurement instruments achieve satisfying levels of validity and reliability.     

A shared document-based annotation tool to support learner-centred collaborative learning

A shared document‐based annotation tool was presented, and its usefulness in two different real‐life web‐based university‐level courses (adult learners, n= 27 and adolescent learners, n= 23) was empirically investigated. The study design embodied three data collection phases: (1) a pretest measuring self‐rated motivation, learning strategies, and social ability; (2) log file data analysis showing actual use of the system features; and (3) a posttest in a form of an email survey. For both groups, the results showed that the level of motivation has a positive effect on activity in the system and the final grade. The learners, who reported to have good time‐management strategies, were the most active users of the system. The level of social ability predicted both the number of consecutive comments in the documents and the threads in document‐related newsgroup discussions. Log file data analysis showed that user activity in the system was positively related to the final grade in both samples. Results of the posttest showed that all the respondents agreed when asked: (1) if the system brought added value to the learning process; (2) if the use of the system changed their studying habits favourably; and (3) if they would like to use the system in other courses.     

Effects of Video Feedback on Social Behaviour of Young People with Mild Intellectual Disability and Staff Responses

The present study evaluates the effects of a multifaceted training procedure on the inappropriate and appropriate social behaviour of young people with mild intellectual disability and on staff responses. The training package included youth training with video feedback and self-management procedures and staff training with video and graphic feedback. The data were collected using a reversal baseline design. The results showed an increase in the occurrence of appropriate behaviour on the part of young people with mild intellectual disability. Inconsistent changes were found for inappropriate social behaviour. The provision of video and graphic feedback successfully modified the performance of direct-care staff members. Recommendations are made for further research on factors related to behaviour change in staff and young people with intellectual disability.
