Virtual landmarking for locality aware peer IDs

In Peer-to-Peer (P2P) networks, it is often desirable to assign node IDs which preserve locality relationships in the underlying topology. Node locality can be embedded into node IDs by utilizing a one dimensional mapping by a Hilbert space filling curve on a vector of network distances from each node to a subset of reference landmark nodes within the network. However this approach is fundamentally limited because while robustness and accuracy might be expected to improve with the number of landmarks, the effectiveness of 1 dimensional Hilbert Curve mapping falls for the curse of dimensionality. This work proposes an approach to solve this issue using Landmark Multidimensional Scaling (LMDS) to reduce a large set of landmarks to a smaller set of virtual landmarks. This smaller set of landmarks has been postulated to represent the intrinsic dimensionality of the network space and therefore a space filling curve applied to these virtual landmarks is expected to produce a better mapping of the node ID space. The proposed approach, the Virtual Landmarks Hilbert Curve (VLHC), is particularly suitable for decentralised systems like P2P networks. In the experimental simulations the effectiveness of the methods is measured by means of the locality preservation derived from node IDs in terms of latency to nearest neighbours. A variety of realistic network topologies are simulated and this work provides strong evidence to suggest that VLHC performs better than either Hilbert Curves or LMDS use independently of each other.

Design patterns for promoting peer interaction in discussion forums in MOOCs

Design patterns are a way of sharing evidence-based solutions to educational design problems. The design patterns presented in this paper were produced through a series of workshops, which aimed to identify Massive Open Online Course (MOOC) design principles from workshop participants’ experiences of designing, teaching and learning on these courses. MOOCs present a challenge for the existing pedagogy of online learning, particularly as it relates to promoting peer interaction and discussion. MOOC cohort sizes, participation patterns and diversity of learners mean that discussions can remain superficial, become difficult to navigate, or never develop beyond isolated posts. In addition, MOOC platforms may not provide sufficient tools to support moderation. This paper draws on four case studies of designing and teaching on a range of MOOCs presenting seven design narratives relating to the experience in these MOOCs. Evidence presented in the narratives is abstracted in the form of three design patterns created through a collaborative process using techniques similar to those used in collective autoethnography. The patterns: “Special Interest Discussions”, “Celebrity Touch” and “Look and Engage”, draw together shared lessons and present possible solutions to the problem of creating, managing and facilitating meaningful discussion in MOOCs through the careful use of staged learning activities and facilitation strategies.

Farmer attitudes and livestock disease: exploring citizenship behaviour and peer monitoring across two BVD control schemes in the UK

The eradication of BVD in the UK is technically possible but appears to be socially untenable. The following study explored farmer attitudes to BVD control schemes in relation to advice networks and information sharing, shared aims and goals, motivation and benefits of membership, notions of BVD as a priority disease and attitudes toward regulation. Two concepts from the organisational management literature framed the study: citizenship behaviour where actions of individuals support the collective good (but are not explicitly recognised as such) and peer to peer monitoring (where individuals evaluate other’s behaviour). Farmers from two BVD control schemes in the UK participated in the study: Orkney Livestock Association BVD Eradication Scheme and Norfolk and Suffolk Cattle Breeders Association BVD Eradication Scheme. In total 162 farmers participated in the research (109 in-scheme and 53 out of scheme). The findings revealed that group helping and information sharing among scheme members was low with a positive BVD status subject to social censure. Peer monitoring in the form of gossip with regard to the animal health status of other farms was high. Interestingly, farmers across both schemes supported greater regulation with regard to animal health, largely due to the mistrust of fellow farmers following voluntary disease control measures. While group cohesiveness varied across the two schemes, without continued financial inducements, longer-term sustainability is questionable

Regimes of risk: the need for a pedagogy for peer groups

Peer groups matter more than we think. In this paper we assert that peer group commitments and affiliations are often the primary social reference in determining the way young people think about and practice risk. It is, we argue, inappropriate to impose adult constructions of risk-taking and anti-social behaviour when trying to assert influence over the decisions and practices young people make in the context of their peers. Prominent in our discussion is a concern that mainstream educational theory and practice focuses disproportionately on the individual and their capacity to make rational and independent choices. We believe that within this individualizing framework, teachers have only a very limited capacity to influence the practices and decisions young people make in the presence of their peers, their friends. To ground this discussion we juxtapose the actions and interactions of two young male peer groups, to highlight their respective constructions of group identity.

Peer groups, power and pedagogy : the limits of an educational paradigm of separation

In contrast to the plethora of literature that suggests that the increasing gulf between teachers and young people is due to the shifting interests and expectations of young people, the focus of this paper is on the roles teachers play in this relationship. Provoking interest is a concern that some of the assumptions that underpin 'mainstream' pedagogic theory and practice might actually contribute, albeit unwittingly, to hardening rather than softening the communication divide. Drawing on an incident that took place between a group of 7–8 year old males in a primary school setting, the authors reveal the limits of a teaching paradigm that encourages teachers to adopt authoritative positions from which to separate and individualise student behaviour. In theoretical terms, they argue that the application of this paradigm asserts an exaggerated notion of agency to individuals in the construction of identity. In practical terms it promotes processes that individualise behaviour as a way of dealing with miscreance. Together these manifest themselves as a 'pedagogy of separation'. The process of building more productive pedagogic relationships, it is concluded, needs to begin with teachers better recognising and engaging with the collective investments of young people.

The social validity of interventions for promoting preschool childrens peer interactions

This analogue study investigated the social validity of classroom interventions designed to promote peer interactions in young children. The influences of child characteristics and diagnostic labels on social validity ratings were examined, as were the relationships among three components of social validity. Forty-two preschool teachers completed a 15-item social validity scale that yielded scores pertaining to intervention goals, procedures and effects. Participants rated three types of intervention, which varied according to individuals targeted and intensity of programming procedures, with reference to one of three case descriptions of children with social interaction problems. Half the participants were provided with the child’s diagnostic label. Results indicated that social validity is affected by interactions between intervention methods and child characteristics. The inclusion of diagnostic labels in the case descriptions had no effect on social validity ratings. Strong positive relationships were found among the components of social validity. Implications for the use of empirically validated interventions in inclusive preschools are discussed.

Teacher and peer assessment of creativity in technology education

This study, part of a PhD thesis, investigates a number of aspects relating to technology education, creativity and the assessment of creativity and aesthetics. Following tuitional sessions, panels of upper primary school children were involved in assessing the creative and aesthetic characteristics of technological products made by other children. Teachers assessed a selection of student drawings for creativity and these results were compared against the corresponding products assessed by the panels of Year 5 children. Subjects were administered a test on their knowledge of technology and these scores were compared to product creativity scores. The results showed high correlations between the assessor ranks for both creativity and aesthetics although there was generally more consistency with creativity. While some subjects produced both creative drawings and products, others showed creativity in only one outcome. A further finding of the investigation identified the relationship between students' knowledge of technology and the creative product constructed by the older children in the study.

Family, school, peer and individual influences on early adolescent alcohol use: first-year impact of the Resilient Families programme

Introduction and Aims:  This study aimed to examine: (a) the influence of family factors relative to school, peer and individual influences on the development of adolescent alcohol use during the first year of secondary school; and (b) the feasibility of preventing adolescent alcohol use by modifying family factors. Design and Methods:  Twenty-four schools in Melbourne, Australia were randomly assigned to either the 'Resilient Families' intervention or a control condition. A baseline cohort of 2315 grade 7 students (mean age 12.3 years) were followed-up one year later (n = 2128 for longitudinal analyses). A sub-set of parents (n = 1166) also returned baseline surveys. Results: The prevalence of lifetime alcohol use in year 7 was 33% and rose to 47% by year 8. Student-reported predictors of year 8 alcohol use included baseline alcohol [Odds Ratio (OR) 3.64] and tobacco use (2.68), and school friend's alcohol (1.41) and tobacco use (1.64). After adjusting for other influences, student-reported family factors were not maintained as significant predictors of year 8 alcohol use. Parent-report predictors of student-reported alcohol use included allowing alcohol use in the home (2.55), parental alcohol use (1.88) and child hyperactivity (1.85). Protective factors included attendance at brief parent education (0.60) and parent involvement in school education (0.65). Discussion and Conclusions: The intervention appeared to benefit education-related outcomes, but no overall effect in reducing student alcohol use was found in year 8. Intervention effects on alcohol misuse may become significant in later secondary school once the entire program has been implemented. Considerable alcohol use was detected in early secondary school,   suggesting that interventions to reduce alcohol use may be usefully implemented prior to this period.

Online self-and-peer-assessment for teamwork in architecture and business communications

There is considerable evidence of general student scepticism regarding the purpose of team assignments and high levels of concern for the fairness of assessment procedures when all members of a team receive the same grade. Some educators are similarly anxious about not only the validity of team grades, but also the need to assess ongoing team processes in addition to the final assignment product. This paper offers self-andpeer-assessment (SAPA) as a fair, valid and reliable method of producing information about ongoing team processes. The paper examines a pilot study investigating an online SAPA tool originally developed for a small class of architecture students. This tool is adapted for use for by students completing team assignment in two further architecture design units and for a very large class of 800 business communication students. The sample students studied on four campuses, as well as in off campus and offshore modes. The paper focuses on the initial stages of the study to demonstrate how researchers from very different backgrounds collaborated to adapt the online tool and implement a pilot study whilst maintaining both comparability of assessment and integrity of research design.

Online self and peer assessment in large, multi-campus, multi-cohort contexts

The increasing use of team assignments within higher education is well documented. The driving forces behind this include desires to facilitate reflective and collaborative learning, to develop generic teamwork skills for graduate employment and to reduce the grading workloads of faculty staff. Students however consistently report dissatisfaction when the assessment of team assignments produces a common grade for all team members. Self-andpeer-assessment (SAPA) is presented as a fair, valid and reliable method of producing information about ongoing team processes. This information can provide ongoing feedback to team members and rich formative data to instructors attempting to assess the team process and students’ teamwork skills. This data can also enable individualised summative assessment in dysfunctional teams or situations of uneven team member contributions. Whilst manual SAPA protocols can work effectively for smaller classes, computer-assisted SAPA offers a solution to the problems of large classes. This paper reports on the early stages of an online SAPA tool, originally developed for small classes of architecture students, adapted for use by very large business communication classes comprising up to 1000 students in a semester. This large unit is delivered on four Australian campuses as well as off-campus and in off-shore mode, by up to fourteen instructors at any one time. The paper documents how three researchers from very different backgrounds worked to create their own research team, implement a pilot study, and adapt the online tool, whilst adhering to comparability of assessment constraints and maintaining integrity of research design.

Sibling peer support group for young people with a sibling using drugs: a pilot study

Siblings of young people abusing drugs are at particular risk for drug abuse and other health compromising behaviors. A Sibling Peer Support Group was developed by the Centre for Adolescent Health (Melbourne, Australia) for young people aged 13 to 18 years with a problematic drug user in their family. Groups aimed to provide support and information, promote harm minimization, and reduce the sense of isolation. The project emanated from the recognized need for specific support for adolescent siblings of problematic drug users. Evaluation of two pilot groups indicated positive benefits for group members, who reported feeling better informed, more supported, and having a reduced sense of isolation. Parents reported that their adolescent attending the group demonstrated improved communication with, and greater understanding and tolerance of, the family member using drugs. Promising indicators at a community level were manifested in enthusiastic collaboration among schools, police and local service agencies, and the organization of a local drug forum. There appeared to be little evidence that the groups inadvertently encouraged drug use. Recruitment of young people into groups was the major challenge for the project, but among drug and alcohol and family organizations there was support for the concept of a Sibling Peer Support Group. A new model to overcome the challenge of recruitment is proposed.

Peer mentoring the first time around : Is it all a matter of negotiation?

In 2002, the senior executive at Deakin University sought applications from staff for academic professional development funding. This was intended to support programs related to the Deakin First Year Initiative, a university-wide coordinated approach to transition. The Faculty of Health & Behavioural Sciences was successful in gaining a grant for the design, implementation and evaluation of a peer mentoring pilot program, which has been introduced this year for students undertaking the Bachelor of Applied Science (Health Sciences). This generic undergraduate program draws from and complements the specialist fields of study on offer in the Faculty. It is very flexible, within given parameters, allowing students to combine study according to their interests, abilities and career aspirations. In this session, we will explore the challenges faced so far by the program managers in devising a program that will successfully cater for approximately 50 first year students undertaking diverse majors across the Faculty.

Managing behavioural symptoms of dementia : Effectiveness of staff education and peer support

This study was designed to investigate the impact of staff education on the behaviour and quality of life of residents with dementia and on staff members' attitudes about working with people with dementia and level of burnout. Staff from three aged care facilities participated in the study (n = 52). These facilities were randomly assigned to one of two intervention groups or a control group. Staff assigned to the intervention groups received an eight-week behaviourally-based programme. Staff from one aged care facility also participated in a peer support group designed to reinforce educational material and facilitate positive changes among staff members. Behavioural symptoms displayed by residents (n = 76) in each of the facilities were also assessed. Assessments were conducted at pre-intervention, post-intervention, three- and six-month follow-up. The results of this study indicated that education or peer support was not associated with an improvement in resident behaviour or quality of life. Education or peer support also did not impact on staff members' level of burnout. There was, however, a change in staff members' attitudes about working with people with dementia. Possible explanations for these findings and implication for further research are considered.

Peer mentoring in an accounting setting : a case study of mentor skill development

This paper provides the background to the adoption of a peer mentoring program including the preparation of mentors and the classroom role of mentors. The paper also includes a discussion of alternative models of peer mentoring and an examination of factors to be considered in adopting mentoring as a teaching and learning resource. Using a case study of third-year undergraduate accounting students who were employed to mentor fellow students in a second-year accounting unit at an Australian university, the paper examines peer mentoring as a classroom resource in the teaching of accounting concepts. The study includes an evaluation of the perceptions of generic skill development by peer mentors illustrating how mentoring can be a reciprocal process, in that the mentor's skills can be enhanced while fulfilling a supporting role to junior students. The programme evaluation also demonstrated that accounting educators could contribute to the development of students' generic skills outside the traditional classroom setting.

A cross-cultural study into peer evaluations of women's leadership effectiveness

Purpose: The present paper is based on a cross-cultural exploration of middle managers in two diverse cultures and aims to focus on how the leadership styles of managerial women are perceived and evaluated. In particular, female and male peer evaluations of leadership effectiveness in Malaysia and Australia are to be explored.

Design/methodology/approach: Surveys from 324 middle managers from Malaysia and Australia were quantitatively analysed. The sample for the study was drawn from organisations in four industry types in both countries.

Findings:  Findings suggest that evaluations of female managers' leadership styles in general, and within the respondent's own organisations, were strongly culture specific, especially in Malaysia. The results reflected the strongly held values, attitudes and beliefs of each country. While this is not unexpected, it does highlight a need to be cautious when interpreting Western research results and attempting to transplant those into other cultures. In Malaysia, female managers were not seen as effective in the leadership styles they adopted in their roles when compared to the Australian female managers' evaluations. Such an evaluation may have had little to do with an objective appraisal of the female managers' capability, but rather with a strongly held cultural belief about the appropriate role of women in society, and in organisations in particular.

Research limitations/implications:  It is suggested that national culture manifests itself in the values, attitudes and behaviours of people. Cultural influences are therefore likely to impact on the way women and men behave in the workplace, particularly when roles of authority and power are evident, and the way in which that behaviour will be evaluated by others. Further research using different samples in different cultures are recommended. In addition, the influence of ethnicity, race or religion in plural countries such as Malaysia and Australia is also worthy of investigation.

Practical implications:  This research suggests that values and attitudes are strongly culture-specific and therefore have the ability to influence evaluations at an organisational level. Such an awareness of cultural influences should guide appropriate human resource practices, particularly within a globalized environment.

Originality/value:  The inclusion of a gender comparison in the data analysis in this paper is a significant attempt to add to the extant knowledge of the cross-cultural research. This is a unique contribution because of the omission of a gender perspective in the previous two seminal studies in culture literature (i.e. Hofstede and House et al.). In addition, the findings suggest that culture-specific influences are important determinants that impose expectations on the role of women differently from men in society and within organisations hence, making the gender comparison of the findings more significant.
