Applying Rating Systems to Challenge Based Cybersecurity Education
As technology becomes a larger part of everyday life, it becomes increasingly more important for CS and CIT students to learn about cyber security during their education. While many cyber security oriented courses exist, it is also necessary that students must be able to work and learn in an environment that resembles a real world context. To address this problem it has become common to adapt cyber security challenges into the classroom as a method for students to put their knowledge into practice. One problem is that these challenges can vary considerably in levels of difficulty, which makes it problematic for students to be able to select a challenge that is an appropriate difficulty for their skill level. A potential solution to this problem could be to adapt a rating system to rank both the students and the challenges. This would then allow the students to easily select challenges that are appropriate for them to engage with by comparing their own rating with the rating of available challenges. In this project we propose methods that could be used to adapt a rating system to an existing cyber security education program. Finally we propose a method to survey students that interact with the program so that the effect of the rating system can be measured
Cryptic complexity in felid vertebral evolution: shape differentiation and allometry of the axial skeleton
Members of the mammalian family Felidae (extant and extinct cats) are grossly phenotypically similar, but display a 300-fold range in body size, from less than 1 kg to more than 300 kg. In addition to differences in body mass, felid species show dietary and locomotory specializations that correlate to skull and limb osteological measurements, such as shape or cross-sectional area. However, ecological correlates to the axial skeleton are yet untested. Here, we build on previous studies of the biomechanical and morphological evolution of the felid appendicular skeleton by conducting a quantitative analysis of morphology and allometry in the presacral vertebral column across extant cats. Our results demonstrate that vertebral columns of arboreal, scansorial and terrestrial felids significantly differ in morphology, specifically in the lumbar region, while no distinction based on dietary specialization was found. Body size significantly influences vertebral morphology, with clear regionalization of allometry along the vertebral column, suggesting that anterior (cervicals and thoracics) and posterior (lumbar) vertebrae may be independently subjected to distinct selection pressures
The analysis of future flood risk in the UK using the Future Flood Explorer
The assessment of future flood risk presented considers three climate change scenarios (a 2°C and 4°C change in Global Mean Temperature by the 2050s and 2080s and a more extreme, but plausible future, the so-called H++ future), and three population growth projections (low, high and no growth). The analysis covers the whole of the UK (England, Wales, Scotland and Northern Ireland) and the risks associated with coastal, fluvial, surface water and groundwater flooding. Eight individual Adaptation Measures (including spatial planning, flood defence, catchment storage) are used to construct five Adaptation Scenarios (including enhanced and reduced levels of adaptation ambition in comparison to present day). Future flood risks for a range of climate, population and adaptation combinations are assessed using the UK Future Flood Explorer. The analysis highlights that significant increases in flood risk are projected to occur as early as the 2020s; a finding that reinforces the need for urgent action. The analysis also highlights that to manage risk effectively under a 2 or 4°C future an enhanced whole system approach to adaptation is needed. This will require action by a broad range of stakeholders, from national level down to individual households and businesses
Optic Nerve Sheath Mechanics in VIIP Syndrome
Visual Impairment and Intracranial Pressure (VIIP) syndrome results in a loss of visual function and occurs in astronauts following long-duration spaceflight. Understanding the mechanisms that lead to the ocular changes involved in VIIP is of critical importance for space medicine research. Although the exact mechanisms of VIIP are not yet known, it is hypothesized that microgravity-induced increases in intracranial pressures (ICP) drive the remodeling of the optic nerve sheath, leading to compression of the optic nerve which in turn may reduce visual acuity. Some astronauts present with a kink in the optic nerve after return to earth, suggesting that tissue remodeling in response to ICP increases may be taking place. The goal of this work is to characterize the mechanical properties of the optic nerve sheath (dura mater) to better understand its biomechanical response to increased ICP

Appraising the Role of the Individual in Political and Social Change Processes: Jung, Camus, and the Question of Personal Responsibility–Possibilities and Impossibilities of “Making a Difference”
The paper is an attempt to open discussion on the role of “the individual” in contemporary progressive and radical political discourse and criticism. Academic stress on the contexts in which individuals operate, while necessary and useful, cuts us off from sources for thinking about such a role. Jung's ideas about the relations of individual and social/collective are important and suggestive yet require extensive revision. Camus's book The Rebel is useful in making such revisions. Centrally, the paper proposes new thinking about “broken” and “fractured” individuals as it probes the limits of personal responsibility. Questions of individual political “type” or “style” are posed, intended to provide a novel account of how political attitudes, engagements and behaviours may be conceptualised.

Carnal critiques: promiscuity, politics, imagination, spirituality and hypocrisy
The author explains the political, psychological and ethical reasons for writing about promiscuity. His previous work on what is ‘more‐than‐personal’ embraced politics and spirituality in the context of psychotherapy. He sets this inquiry in the historical context of the fortieth anniversary of the ‘sexual revolution’ of the 1960s, reviewing critically the debate as to whether there was or was not a revolution. The manifold connections between sexual promiscuity and political critique are explored. This sets the scene for the location of promiscuous phenomena within a spiritual or transpersonal domain. Promiscuities (in the plural) rather than monolithic promiscuity are surveyed in terms of sex and sexual diversity. Promiscuity is reviewed in terms of imaginative process. Finally, the hypocritical attitudes towards promiscuity on the part of many (but not all) psychotherapists are explored with the intention of discovering the reasons for this phenomenon
