Why Secondary Schools Do Not Implement Far-Reaching Smoke-Free Policies: Exploring Deep Core, Policy Core, and Secondary Beliefs of School Staff in the Netherlands
Why Secondary Schools Do Not Implement Far-Reaching Smoke-Free Policies: Exploring Deep Core, Policy Core, and Secondary Beliefs of School Staff in the Netherlands
Background: Secondary schools that implement smoke-free policies are confronted with students who start smoking outside their premises. One solution is to complement smoke-free policies with prohibitions for all students to leave the school area during school hours, technically making school hours a smoke-free period. However, there are strikingly few Dutch secondary schools that implement this approach. This study explores why staff members in the Netherlands decide not to implement smoke-free school hours for all students. Method: We interviewed 13 staff members, with different functions, from four secondary schools. The analysis was informed by the Advocacy Coalition Framework (ACF) to delve into the values, rationales, and assumptions of staff with the aim to identify deep core, policy core, and secondary beliefs. Results: We identified six beliefs. Two deep core beliefs are that schools should provide adolescents the freedom to learn how to responsibly use their personal autonomy and that schools should only interfere if adolescents endanger or bother others. Three policy core beliefs identified included the following: that smoking is not a pressing issue for schools to deal with; that schools should demarcate their jurisdiction to intervene in adolescents’ lives in time, space, and precise risk behavior; and that implementing smoke-free school hours would interfere with maintaining positive student-staff relationships. One secondary belief identified was that smoke-free school hours would be impossible to enforce consistently. Conclusion: This paper was the first to demonstrate the many beliefs explaining why schools refrain from voluntary implementing far-reaching smoke-free policies

Security Scenario Generator (SecGen): A Framework for Generating Randomly Vulnerable Rich-scenario VMs for Learning Computer Security and Hosting CTF Events
Computer security students benefit from hands-on experience applying security tools and techniques to attack and defend vulnerable systems. Virtual machines (VMs) provide an effective way of sharing targets for hacking. However, developing these hacking challenges is time consuming, and once created, essentially static. That is, once the challenge has been "solved" there is no remaining challenge for the student, and if the challenge is created for a competition or assessment, the challenge cannot be reused without risking plagiarism, and collusion. Security Scenario Generator (SecGen) can build complex VMs based on randomised scenarios, with a number of diverse use-cases, including: building networks of VMs with randomised services and in-thewild vulnerabilities and with themed content, which can form the basis of penetration testing activities; VMs for educational lab use; and VMs with randomised CTF challenges. SecGen has a modular architecture which can dynamically generate challenges by nesting modules, and a hints generation system, which is designed to provide scaffolding for novice security students to make progress on complex challenges. SecGen has been used for teaching at universities, and hosting a recent UK-wide CTF event
Fiber-top cantilever:a new generation of micromachined sensors for multipurpose applications
Fiber-top cantilevers are new monolithic devices obtained by carving a cantilever out of the edge of a single-mode optical fiber. Here we report evidences of their potential impact as sensing devices for multipurpose applications
