Hesitantly into the arena: An account of trainee teachers' and sixth form students' preliminary attempts to enter into dialogue through email

Teacher training is increasingly accountable to central government. Trainees – the word itself is significant – are expected to demonstrate competence in a wide range of professional standards if they are to achieve qualified teacher status. Training partnership schools, understandably, impose their own conditions for entry into their 'communities of practice'. In these circumstances, trainees – and their trainers – have increasingly fewer opportunities for risk taking or for exploring new configurations of the teacher pupil relationship.
This paper describes an attempt to exploit the potential of email as a means of granting access to a 'pedagogical arena' in which trainees and students might attempt to negotiate their own ways of working together. It concludes by suggesting that both groups found this a challenging task and by noting that the trainers involved decided that, if the project were to run again, a certain amount of autonomy would need to be sacrificed to direction.     

基于认证测试的鲁棒电子邮件协议形式化分析(英文)

基于认证测试方法及strand space模型,形式化分析了具有完美前向机密性的鲁棒电子邮件协议,指出该协议存在安全缺陷.同时给出了针对该协议的中间人攻击方法,即攻击者在协议的接收阶段通过伪造消息即可欺骗通信双方,使通信双方与其共享错误的会话密钥,由此使得协议的完美前向机密性得不到保证,针对协议的上述缺陷,提出一种改进方案,即通过在协议的接收阶段加入相应的签名信息,以保证改进协议能够克服中间人攻击并且提供完美前向机密性.最后,基于认证测试方法及strand space模型,形式化证明了改进协议在发起者、接收者及服务器之间的安全认证,确保了改进协议具备真正的完美前向机密性.

Analysis of predatory emails in early career academia and attempts at prevention

Predatory publishers—those who do not adhere to rigorous standards of academic practice such as peer review—are increasingly infiltrating biomedical databases, to the detriment of the wider scientific community. These publishers frequently send unsolicited ‘spam’ emails to generate submission to their journals, with early career researchers (ECR) particularly susceptible to these practices because of pressures such as securing employment and promotion. This analysis sought to record and characterize the emails received over the course of a PhD and post-doctoral position (~8 years), as well as attempts to unsubscribe from such emails, using a progressive and step-wise manner. A total of 1,280 emails identified as academic spam were received (990 journal invitations, 220 conference invitations, 70 ‘other’). The first email was received 3 months after registration for an international conference. Attempts at unsubscribing were somewhat effective, whereby implications of reporting to respective authorities resulted in a 43% decrease in emails, although did not eliminate them completely, and therefore alternative approaches to eliminating academic spam may be needed. Ongoing education about predatory publishers, as well as action by key academic stakeholders, should look to reduce the impact these predatory publishers have upon the wider literature base.
