The ascent of asymmetric risk in information security: an initial evaluation

Dramatic changes in the information security risk landscape over several decades have not yet been matched by similar changes in organizational information security which is still mainly based on a mindset that security is achieved through extensive preventive controls. As a result, maintenance cost of information security is increasing rapidly, but this increased expenditure has not really made an attack more difficult. The opposite seems to be true, information security attacks have become easier to perpetrate and appear more like information warfare tactics. At the same time, the damage caused by a successful attack has increased significantly and may sometimes become critical to an organization. In this paper we evaluate one particular extremely asymmetric risk where a strongly motivated attacker unleashes a prolonged attack on an organization with the aim to do maximum damage, and suggest that the probability of such an attack is increasing. We discuss how preventive controls are unlikely to ever be effective against such an attack and propose more advanced strategies that aim to limit the damage when such an attack occurs. One crucial lesson to be learned for those organizations that are dependant on their information security, such as critical infrastructure organizations, is the need to deny motivated attackers access to any information about the success of their attack. Successful deception in this area is likely to significantly reduce any potential escalation of the incident.

Keeping all students on the learning path

A powerful notion to guide thinking about whole-class mathematics teaching is Vygotsky’s zone of proximal development (ZPD). Our research with primary and secondary teachers over the last six years has identified roles of teachers in relation to the ZPD, and ways of overcoming some typical barriers to students’ movement through their zones. Methods have included focus groups of experts, video analysis of classroom interactions, classroom observation, and analysis of lesson plans and teachers’ reflections teaching processes their outcomes. The research has involved the gradual development, trailing, evaluation, and adjustment of a six-component model for planning and teaching mathematics. The focus of this paper is on the use of one of its components, “differentiated learning trajectories”.

From ‘consulting pupils’ to ‘pupils as researchers’ : a situated case narrative

Schools in England are now being encouraged to 'personalise' the curriculum and to consult students about teaching and learning. This article reports on an evaluation of one high school which is working hard to increase student subject choice, introduce integrated curriculum in the middle years and to improve teaching and learning while maintaining a commitment to inclusive and equitable comprehensive education. The authors worked with a small group of students as consultants to develop a 'student's-eye' set of evaluative categories in a school-wide student survey. They also conducted teacher, student and governor interviews, lesson and meeting observations, and student 'mind-mapping' exercises. In this article, in the light of the findings, the authors discuss the processes they used to work jointly with the student research team, and how they moved from pupils-as-consultants to pupils-as-researchers, a potentially more transformative/disruptive practice. They query the notion of 'authentic student voice' and show it as discursive and heterogeneous: they thus suggest that both a standards and a rights framings of student voice must be regarded critically.

Living improvement : a case study of a secondary school in England

Schools in England are being urged to personalize the curriculum and make school experiences more responsive to all students. We report on an evaluation project which investigated innovation in teaching and learning in a successful secondary school in the north of England. Data were gathered from a sample of teaching staff, a questionnaire to all students, lesson and meeting observations, and meetings with the governing body and parents: the student-guided evaluation canvassed recent and planned changes to the structure and experience of teaching and learning. This article illuminates how one school is breaking the ‘traditional schooling rules’ that limit improvement and how in doing so it is developing new insights about the nature and process of improvement. We show how staff and students have been engaged in the change process, and focus in particular on analysing the interplay between improvement as a plan, a practice and a lived experience.

Perceptions of athletic competence and fear of negative evaluation during physical education

Background. Physical education (PE) aims to enhance self-esteem, develop sporting interests and to encourage a physically active life-style. However, little is known about how a fear of negative evaluation (FNE), the socially evaluative aspect of social anxiety, affects children's attitudes to PE.

Aim. The aim of the study was to investigate the relationships between perceived athletic competence and FNE within PE lessons, specifically looking at differences between boys and girls and primary and secondary schools.

Sample. The participants were 192 children in three primary schools (N=85, mean age=9.5±1.1 years) and two secondary schools (N=107, mean age=14.5±0.8 years) from rural areas of North Wales and the Midlands region of England.

Methods. The participants completed the Brief-FNE Scale and the Self-Perception Profile for Children immediately post-lesson on one occasion.

Results. Girls had higher FNE but lower perceptions of athletic competence than did boys. Older girls had higher FNE and lower perceived competence than the remaining three groups. Additionally, a significant and reverse but weak correlation was observed between girls' perceived athletic competence and FNE.

Conclusions. The findings suggest that girls with a high FNE report lower perceptions of their athletic competence. Individuals who are high in FNE behave in ways to avoid the prospect of being evaluated negatively. However, they may seek feedback from significant others as a signal that unfavourable evaluations have been avoided. Therefore, positive, encouraging feedback used in child-centred learning strategies may foster feelings of competence in boys and girls and could reduce the girls' social anxiety.

Geocaching : a worldwide treasure hunt enhancing the mathematics classroom

Geocaching is a global treasure hunt that invites people of all ages to discover actively the beauty of their environment through the assistance of a Global Positioning Systems (GPS), mathematical know-how, and a bit of foraging. If you are seeking a new way to engage your students in a motivating and exciting real-life task, then geocaching might be the answer. The purpose of this article is to describe the experience of our shcool-based geocaching project undertaken with children in Prep (5-6) and the senior primary Grades (ages 10-12). We will share the potential for mathematical learning and engagement. It is argued that geocaching provides the opportunity for rich engagement with key mathematical concepts that goes beyond what can be acheived during a typical lesson.

Evaluation of thermal and visual comfort in offices considering realistic input data and user behaviour in building simulation

Thermal and visual comfort play a very important role regarding the satisfaction of occupants with their working environments. The most effective method to achieve thermal comfort in offices is to reduce cooling loads in order to avoid additional energy-consuming devices for cooling. Building simulation software can be a helpful tool for optimisation, and typically standard values for the influencing parameters are used in order to ensure compliance to norms and regulations.

In practice many of those parameters turn out to be different compared to the simulation assumptions and the reasons may be the chosen room or building related properties as well as the user behaviour influenced by the task and the corporate culture of the company.

This paper investigates exemplary for the climate of Hamburg, Germany and a naturally ventilated typical office room, the optimisation potential of the building- and user-related parameters for thermal comfort, daylighting and view when using realistic input data for building simulation. The study has been conducted with the EnergyPlus based simulation software “Primero-Komfort” [1].

'I do lots of things that the University would not approve of'. What counts as professional knowledge in the eyes of pre-service and beginning teachers -implications of the encounter for the role of teacher educators in pre-service middle school preparati

This paper is an account of teacher educator perceptions of the take-up by beginning teachers of the values and practices advocated in pre-service education. Methodologically grounded in a critical ethnographic account, two teacher educator/researchers retell their understanding of the one-month experience as middle school classroom teachers in an allocated school. The paper examines the consequences of what counts as professional knowledge in the eyes of pre-service and beginning teachers and the implications of the encounter for the role of teacher educators in preservice preparation. The purpose of the research is to consider the well-researched issue of the rejection of academic training (to greater or lesser extents) that is experienced by very many preservice and beginning teachers at some stage after experience in schools. As an exemplary colleague teacher said to us as we negotiated our participation in the school: "I do lots of things that the University would not approve of". Our argument is that teacher education needs the kind of participatory inquiry represented by the undertaking and methodology of this project. The paper is the 'primary record' (Carspecken 1996) of the research and works to open the next phase, the dialogical stage of the research process.

Developing a culturally-specific peace curriculum for Vietnamese primary schools : a case study of participatory action research in cross-cultural design

In 2003 the International Conflict Resolution Centre at the University of Melbourne, Australia, produced a primary school teaching manual for UNESCO Vietnam in consultation with ASP schoolteachers and principals. The finished manual included lessons plans and materials for a five year, 50 lesson peace education course. The Manual is one of the first examples of a systematic core national curriculum in peace education worldwide.

Development of the Teaching Manual posed a number of challenges including differences in language, culture, government and education system. To meet these challenges, a Participatory Action Research approach was central in the project’s development and curriculum design. This case study is offered as a model for effective cross-cultural curriculum development of peace education materials. In particular, the creation of a systematic core course in peace education and the use of UNESCO’s peace keys are outlined as innovative aspects of the project.

Multi-theoretic approaches to understanding the science classroom

Multi-camera on-site video technology and post-lesson video stimulated interviews were used in a purposefully inclusive research design to generate a complex data set amenable to parallel analyses from several complementary theoretical perspectives. The symposium reports the results of parallel analyses employing positioning theory, systemic functional linguistics, distributed cognition and representational analysis of the same nine-lesson sequence in a single science classroom during the teaching of a single topic: States of Matter. Without contesting the coherence and value of a well-constructed mono-theoretic research study, the argument is made that all such studies present an inevitably partial account of a setting as complex as the science classroom: privileging some aspects and ignoring others. In this symposium, the first presentation examined the rationale for multi-theoretic research designs, highlighting the dangers of the circular amplification of those constructs predetermined by the choice of theory and outlining the intended benefits of multi-theoretic designs that offer less partial accounts of classroom practice. The second and third presentations reported the results of analyses of the same lesson sequence on the topic “states of matter” using the analytical perspectives of positioning theory and systemic functional linguistics. The final presentation reported the comparative analysis of student learning of density over the same three lessons from distributed cognition and representational perspectives. The research design promoted a form of reciprocal interrogation, where the analyses provided insights into classroom practice and the comparison of the analyses facilitated the reflexive interrogation of the selected theories, while also optimally anticipating the subsequent synthesis of the interpretive accounts generated by each analysis of the same setting for the purpose of informing instructional advocacy.

Learning science through representational generation/negotiation

This paper will describe the key features and theoretical underpinnings of a representation-intensive pedagogy developed in a six-year research program, and its relationship to the epistemic practices of science. The pedagogy draws on socio cultural, pragmatist perspectives on learning and cognition that view knowledge as grounded in multi modal representations that are discursively generated, negotiated and coordinated in science classrooms. From this perspective, the learning challenges identified by research in the conceptual change tradition are seen as inherently representational in nature, and the central feature of the pedagogy involves students generating representations in response to structured challenges. The paper will interrogate the key aspects of the pedagogy and the way it supports learning, using evidence from a range of units designed by the researchers working in partnership with a small group of teachers. The role of representations in supporting learning will be explored in terms of the way they afford and productively constrain knowledge generation, mirroring the epistemic practices of science. Lesson transcripts, and examples of student artefacts will be presented to demonstrate significant reasoning and learning outcomes.

Enactive research : transversal possibilities for expanding the imaging of science

This paper explores the notion of the expanded image as a transdisciplinary interaction between people and environments. In support of this proposition, images and imaging will be discussed through a series of transformative steps: from the diagram to the biogram and from the biogram to biotopology. Two research projects, exemplary of a transdisciplinary approach, inform the move to biotopology (the continuous surface of interactions tied to imaging practices): first, theories of enaction in cognitive science foreground co-selective processes and the precariousness of self- organizing systems and supply new ways of imaging body-environment relationships (Stewart et al 2010; Thompson 2007; and Varela et al 1993); and second, the procedural architecture of artist- turned-architects Arakawa and Gins foregrounds the reconfigurability of the co-selective process that becomes an enactive practice. These approaches suggest that if the image were expanded to include the intersection of the human organism’s behaviors, artifacts (such as images) and built- environments, then the ‘person’ whose myriad surfaces flicker towards future action, might become the best description of an expanded form of imaging, always in process and flickering towards future action. The many and non-locatable surfaces of person would defy disciplinary boundaries and interfere with habitual patterns of imaging. Ultimately, the aim of expanding imaging practices is to expand an embodied capacity to configure and reconfigure conceptual and material realms.
