Peer Effects in Adolescent Cannabis Use: It's the Friends, Stupid

This paper examines peer effects in adolescent cannabis use from several different reference groups, exploiting survey data that have many desirable properties and have not previously been used for this purpose. Treating the school grade as the reference group, and using both neighbourhood fixed effects and IV for identification, we find evidence of large, positive, and statistically significant peer effects. Treating nominated friends as the reference group, and using both school fixed effects and IV for identification, we again find evidence of large, positive, and generally statistically significant peer effects. Our preferred IV approach exploits information about friends of friends – ‘friends once removed’, who are not themselves friends – to instrument for friends’ cannabis use. Finally, we examine whether the cannabis use of schoolmates who are not nominated as friends – ‘non-friends’ – influences
own cannabis use. Once again using neighbourhood fixed effects and IV for identification, the evidence suggests zero impact. In our data, schoolmates who are not also friends have no influence on adolescent cannabis use.

Peer tutoring in a medical school: perceptions of tutors and tutees

Background: Peer tutoring has been described as “people from similar social groupings who are not professional teachers helping each other to learn and learning themselves by teaching”. Peer tutoring is well accepted as a source of support in many medical curricula, where participation and learning involve a process of socialisation.
Peer tutoring can ease the transition of the junior students from the university class environment to the hospital workplace. In this paper, we apply the Experienced Based Learning (ExBL) model to explore medical students’ perceptions of their experience of taking part in a newly established peer tutoring program at a hospital based
clinical school.
Methods: In 2014, all students at Sydney Medical School – Central, located at Royal Prince Alfred Hospital were invited to voluntarily participate in the peer tutoring program. Year 3 students (n = 46) were invited to act as tutors for Year 1 students (n = 50), and Year 4 students (n = 60) were invited to act as tutors for Year 2 students (n = 51). Similarly, the ‘tutees’ were invited to take part on a voluntary basis. Students were invited to attend focus groups, which were held at the end of the program. Framework analysis was used to code and categorise data into themes.
Results: In total, 108/207 (52 %) students participated in the program. A total of 42/106 (40 %) of Year 3 and 4 students took part as tutors; and of 66/101 (65 %) of Year 1 and 2 students took part as tutees. Five focus groups were held, with 50/108 (46 %) of students voluntarily participating. Senior students (tutors) valued the opportunity to practice and improve their medical knowledge and teaching skills. Junior students (tutees) valued the opportunity for additional practice and patient interaction, within a relaxed, small group learning environment.
Conclusion: Students perceived the peer tutoring program as affording opportunities not otherwise available within the curriculum. The peer teaching program provided a framework within the medical curriculum for senior students to practice and improve their medical knowledge and teaching skills. Concurrently, junior students were provided with a valuable learning experience that they reported as being qualitatively different to traditional teaching by faculty.

The influence of experimental design on the magnitude of the effect size -peer tutoring for elementary, middle and high school settings: A meta-analysis

A meta-analysis was undertaken on a form of cooperative learning, peer tutoring. The effects of experimental design on outcomes were explored, as measured by Effect Size (ES). Forty three articles with 82 effect size studies were included in the meta-analysis. Highest ES were reported for quasi-experimental studies. ES reduced as experimental design moved from single pre-test factor matched, to multiple-factor matched randomized controlled trials. ES reduced when designs used standardised, rather than self-designed measures. The implications for future meta-analyses and research in cooperative learning are explored.

Peer-to-peer video streaming

The Internet as a video distribution medium has seen a tremendous growth in recent years. Currently, the transmission of major live events and TV channels over the Internet can easily reach hundreds or millions of users trying to receive the same content using very distinct receiver terminals, placing both scalability and heterogeneity challenges to content and network providers. In private and well-managed Internet Protocol (IP) networks these types of distributions are supported by specially designed architectures, complemented with IP Multicast protocols and Quality of Service (QoS) solutions. However, the Best-Effort and Unicast nature of the Internet requires the introduction of a new set of protocols and related architectures to support the distribution of these contents. In the field of file and non-real time content distributions this has led to the creation and development of several Peer-to-Peer protocols that have experienced great success in recent years. This chapter presents the current research and developments in Peer-to-Peer video streaming over the Internet. A special focus is made on peer protocols, associated architectures and video coding techniques. The authors also review and describe current Peer-to-Peer streaming solutions. © 2013, IGI Global.

Students’ engagement in school and peer relations: A literature review

Este E-Book reúne um conjunto de investigações apresentadas no “I Congresso Internacional Envolvimento dos Alunos na Escola: Perspetivas da Psicologia e Educação” (ICIEAE), organizado no âmbito do “Projeto PTDC/CPE-CED/114362/2009 - Envolvimento dos Alunos na Escola: Diferenciação e Promoção” (EAE-DP), financiado pela Fundação para a Ciência e a Tecnologia (FCT).

An Exploration of the Use of Coaching and Mentoring in the Supervision of Doctoral Students in UK University Business Schools

Purpose: to consider and evaluate the student and supervisor experience of doctoral supervision (dyadic and triadic) and specifically the value of using coaching and mentoring approaches (process and relationship) in supervisory practice. Design/methodology/approach: phase one is a mixed methods study exploring the use of coaching and mentoring in doctoral supervision on traditional and taught doctoral programmes in one UK university business school. The focus is on developing a conceptual model for doctoral supervisory practice for the transfer of learning and the improvement of practice. Phase two will be a collaborative action research study in a range of UK university business schools to use, reflect on and refine the conceptual model of supervision. Findings: the initial findings from phase one will be reported on at the conference presentation. Research limitations/implications: we have tentative agreements from four UK university business schools for phase two (subject to ethics approval). Practical implications: students and supervisors participating in the research will benefit from having the opportunity to review and improve their practice; the participating business schools will have the opportunity to review and potentially revise their doctoral student and supervisor training; and a business school’s reputation for high quality doctoral supervision could be enhanced. Social implications: could potentially benefit numerous future students and supervisors across a wide range of UK university business schools. Originality/value: there does not appear to be any previously published research on the use of coaching and mentoring in doctoral supervision in UK university business schools for the transfer of learning and improvement of practice.

Patients’ Views: Peer Support Worker On Inpatient Wards

Purpose: To explore patients’ experiences of intentional mental health peer support (PS) Design/methodology/approach: Seven in depth interviews were carried out by an independent researcher with individual inpatients who volunteered via a PS worker following leaflet and poster distribution explaining the research on the two wards. Each recorded interview of thirteen questions was transcribed verbatim by the researcher and analysis identified common themes across the interviews. Findings: An overarching theme of communication with patients was identified together with six main themes: person centeredness, practical support, building connections, emotional support, modelling hope, and recovery interventions. There were no negative comments expressed by interviewees. Research limitations/implications: Small scale qualitative research allows in-depth exploration of experiences which is valuable in informing the further development of peer support. Originality/value: There are very few published reports of inpatient experiences of peer support in inpatient settings.

Supporting Completion of an Online Continuing Professional Development Programme For Newly Qualified Practitioners: a Qualitative Evaluation

Background: Development programmes to support newly qualified practitioners gain confidence in their first professional role often show varied levels of engagement, due to competing priorities and demands. In Scotland, the Flying Start NHS® programme uses a structured programme of online and work-based learning with associated mentoring, to support individuals through an often difficult transition to become capable, confident practitioners. . Whilst the programme was generally well received, the factors leading to widely varying completion rates between professions and organisations were not well understood. Aim: to identify the factors leading to successful completion of Flying Start, a transition programme for newly qualified practitioners. Method: A qualitative approach was adopted to gather data from two groups of participants. Semi-structured telephone interviews were conducted with strategic and management level participants (n=23), from five health boards in Scotland. Semi-structured interviews (n=22) and focus groups (n=11) were conducted with practitioners within 6 months either side of completing the programme. The interviews were transcribed and analysed using framework analysis. Results: Four key themes related to successful completion emerged from the analysis: organisational support; the format of the programme; understanding completion; motivation and incentives to complete. Factors leading to successful completion were identified at programme, organisational and individual level. These included clear communication and signposting, up-to-date and relevant content, links with continuing professional development frameworks, effective leadership, mentor and peer support, setting clear standards for assessment, and facilitating appropriate IT access. Conclusions: A strong strategic commitment to embedding a development programme for newly qualified practitioners can ensure the necessary support is available to encourage timely completion. The mentor’s role - to provide face-to-face support - is identified as a key factor in completion and is achieved through setting attainable targets, monitoring progress, and providing motivation. However organisational structures that facilitate the mentoring relationship are also necessary.

Replicating the Networking, Mentoring and Venture Creation Benefits of Entrepreneurship Centres on a Shoestring: A Student-centred Approach to Entrepreneurship Education and Venture Creation

As support for both university-level entrepreneurial education and the use of experiential learning methods to foster student entrepreneurs increases, so too have the number of university-established or affiliated entrepreneurship centers. The activity at the center of this study aimed to combine experiential learning methods with assets associated with entrepreneurship centers, including venture creation, networking, and mentoring. Students were invited to participate in a competition wherein they were guided through the business creation process and pitched their ideas to investor judges who chose the winner and provided capital start-up funding and consulting. This research puts forth that university faculty at institutions without entrepreneurship centers can organize experiences to provide the benefits of entrepreneurship centers. The study used interviews to find that many of the benefits of entrepreneurship centers were able to be replicated using this method. The project is outlined, outcomes are analyzed, and the results and lessons learned are discussed.

Remote experimentation network - yielding an inter-university peer-to-peer e-service

The goal of this paper is to discuss the benefits and challenges of yielding an inter-continental network of remote laboratories supported and used by both European and Latin American Institutions of Higher Education. Since remote experimentation, understood as the ability to carry out real-world experiments through a simple Web browser, is already a proven solution for the educational community as a supplement to on-site practical lab work (and in some cases, namely for distance learning courses, a replacement to that work), the purpose is not to discuss its technical, pedagogical, or economical strengths, but rather to raise and try to answer some questions about the underlying benefits and challenges of establishing a peer-to-peer network of remote labs. Ultimately, we regard such a network as a constructive mechanism to help students gain the working and social skills often valued by multinational/global companies, while also providing awareness of local cultural aspects.

Stratification and peer effects: An analysis of Lisbon public schools

Educational stratification has been a difficult subject to deal with having yet no study shown a quantitative measure of it. Using the idea of distribution comparison a measure based on parents’ education is built for the primary schools in Lisbon. Upon the confirmation that Lisbon is stratified, I use the measure of peer effects based on stratification and determine its impact on test scores, concluding that the existence of stratification improves scores of students in schools with more educated parents and decreases scores of students in schools with less educated parents. Moreover, using fixed effects I derive the conclusion that the measure of peers’ characteristics helps explain most of differences among schools.

Community indentification in peer-t-peer collaborative consumption services

Even though collaborative consumption (CC) is gaining economic importance, research in CC is still in its infancy. Consumers’ reasons for participating have already been investigated but little research on consequences of participation has been conducted. This article examines whether interactions between customers in peer-to-peer CC services influence the willingness to coproduce service outcomes. Drawing on social exchange theory, it is proposed that this effect is mediated by consumers’ identification with the brand community. Furthermore, continuance intention in CC is introduced as a second stage moderator. In a cross-sectional study, customers of peer-to-peer accommodation sharing are surveyed. While customer-to-customer interactions were found to have a positive effect on brand community identification, brand community identification did not positively affect co-production intention. Surprisingly, the effect of brand community identification on co-production intention was negative. Moreover, continuance intention of customers did not moderate this relationship. Bearing in mind current challenges for researchers and companies, theoretical and managerial implications are discussed.
