How to increase ethical awareness in cybersecurity decision-making

Cybersecurity technologies offer secure channels to enable the confidentiality, integrity, and availability of data and services. Human factors; e.g. demographics, personality traits, and human values, which are linked with greater cybersecurity vulnerabilities, have drawn less attention. It is important to understand how to increase ethical awareness for cybersecurity professionals via training. This ethical awareness helps professionals make better moral judgments prior to final decisions and reduces the risk of unexpected human implications. To sensitise players to five cybersecurity ethical principles (beneficence, non-maleficence, justice, autonomy, and explicability), we created a serious game. This game allows players to explore multiple cybersecurity scenarios based on these five cybersecurity ethical principles. Although the analysis does not support the claim that the game increased ethical awareness in general, it did help promote better ethical understanding in some cases where players advanced from providing non-ethical to ethical justifications in a cybersecurity scenario after playing the game

Manipulating Chain Type and Flail Drum Speed for Better Fibre Recovery in Chain-Flail Delimber-Debarker-Chipper Operations

A chain-flail delimber-debarker-chipper (CFDDC) was adapted for treating smaller trees than normal by replacing the standard flails with lighter ones, and by reducing flail drum rotation speed. The machine produced 16 full containers (24 t each) for the standard configuration and 24 full containers for the innovative one. For each container the researchers measured: original tree mass, chip mass, time consumption and fuel use. Results indicated that the innovative setting accrued a 12% improvement on fiber recovery compared with the standard setting (control). At the same time, productivity increased by 20% and fuel consumption was reduced by 30%. Product quality was largely unaffected, with bark content remaining below the 1% threshold specification. If at all, product quality was improved through the reduction of fine particles, possibly derived from less diffused fraying. These results have triggered the real scale adoption of the new setting by contractors who participated in the study. The success of the innovative treatment is likely explained by its better alignment with the weaker structure of small trees from low-yielding stands

Using next-generation sequencing to determine diversity of horse intestinal worms:Identifying the equine ʼnemabiome'

Next generation sequencing of DNA from nematode eggs has been utilised to give the first account of the equine ‘nemabiome’. In all equine faecal samples investigated, multiple species of Strongylidae were detected; ranging from 7.5 (SEM 0.79) with 99+% identity to sequences in the NCBI database to 13.3 (SEM 0.80) with 90+% identity. This range is typical of the number of species described previously in morphological studies using large quantities of digesta per animal. However, the current method is non-invasive, relies on DNA analysis avoiding the need for specialist microscopy identification and can be carried out with small samples providing significant advantages over current methods

Morality meters and their impacts on moral choices in videogames: a qualitative study

Morality meters are a commonly used mechanic in many ethically notable video games. However, there have been several theoretical critiques of such meters, including that people can find them alienating, they can instrumentalise morality, and they reduce morality to a binary of good and evil with no room for complexity. While there has been much theoretical discussion of these issues, there has been far less empirical investigation. We address this gap through a qualitative study that involved participants playing a custom-built visual novel game (The Great Fire) with different intuitive and counter-intuitive morality meter settings. Overall, we found that players’ attitudes towards the morality meter in this game was complex, context sensitive and variable throughout gameplay and that the intuitiveness of the meter encouraged participants to treat the meter more ‘as a moral guide’ that prompts reflection and less ‘as a score’ to be engaged with reactively

Greater rewards in videogames lead to more presence, enjoyment and effort

There is currently limited understanding of whether and how different amounts and diversity of virtual rewards impact on the player experience. A repeated-measures experiment was undertaken in which participants (N = 59) were compared on subjective measures (competence, presence-immersion, tension, effort and enjoyment), as well as psychophysiological measures (electrodermal activity and heart-beat rate), during the play of a videogame with three levels of video game reward (high, medium, low). Effort, enjoyment and presence-immersion significantly varied across conditions such that they were greater when all rewards were present compared to one or both of the other conditions. Heart-beat rate was found to vary across conditions consistent with the explanation that greater rewards lead to greater arousal. Our study suggest a number of advantages to greater amount and diversity of virtual rewards in the context of a casual videogame, with potential application to the design of new gamification systems

The influence of riparian invasion by the terrestrial shrub Lonicera maackii on aquatic macroinvertebrates in temperate forest headwater streams

The ecology of headwater streams is tightly linked to the riparian zone through organic matter subsidies which are highly susceptible to alteration due to biological invasion. Lonicera maackii is a non-native shrub that is a highly successful invader of headwater stream riparian zones in the American Midwest. We assessed effects on benthic macroinvertebrates across a gradient of invasion intensity from references sites with minimal invasion to a site that had a very heavy invasion. Benthic macroinvertebrates were sampled throughout the year and compositional differences were assessed using Non-metric Multidimensional Scaling ordination, and by comparing the prevalence of sensitive (Ephemeroptera, Plectoptera, and Trichoptera: EPT) and tolerant (Chironomidae) macroinvertebrate taxa. We found strong evidence of variation among macroinvertebrate communities across the invasion gradient (ANOSIM R = 0.215, P = 0.004) and particularly strong separation between one of our reference sites with minimal invasion and the site with the heaviest invasion. Analysis of EPT taxa indicated a significant overall effect and pairwise comparisons indicated that the site with the heaviest invasion had the lowest percentage of sensitive taxa (P \u3c 0.05). Our analysis of chironomids did not yield a statistically discernable effect, although the pattern of the data suggest higher dominance in the site with the heaviest invasion. These stream-scale results bolster prior laboratory and field experiments and provide evidence that terrestrial invasion of L. maackiiimpacts the benthic community present in headwater streams. These results provide impetus to re-focus stream management recommendations to include practices that control invasive plants in riparian forests

Modelling CO formation in the turbulent interstellar medium

We present results from high-resolution three-dimensional simulations of turbulent interstellar gas that self-consistently follow its coupled thermal, chemical and dynamical evolution, with a particular focus on the formation and destruction of H2 and CO. We quantify the formation timescales for H2 and CO in physical conditions corresponding to those found in nearby giant molecular clouds, and show that both species form rapidly, with chemical timescales that are comparable to the dynamical timescale of the gas. We also investigate the spatial distributions of H2 and CO, and how they relate to the underlying gas distribution. We show that H2 is a good tracer of the gas distribution, but that the relationship between CO abundance and gas density is more complex. The CO abundance is not well-correlated with either the gas number density n or the visual extinction A_V: both have a large influence on the CO abundance, but the inhomogeneous nature of the density field produced by the turbulence means that n and A_V are only poorly correlated. There is a large scatter in A_V, and hence CO abundance, for gas with any particular density, and similarly a large scatter in density and CO abundance for gas with any particular visual extinction. This will have important consequences for the interpretation of the CO emission observed from real molecular clouds. Finally, we also examine the temperature structure of the simulated gas. We show that the molecular gas is not isothermal. Most of it has a temperature in the range of 10--20 K, but there is also a significant fraction of warmer gas, located in low-extinction regions where photoelectric heating remains effective.Comment: 37 pages, 15 figures; minor revisions, matches version accepted by MNRA

Subaltern geographies: Geographical knowledge and postcolonial strategy

In recent years a small but rich geographical literature has engaged with Subaltern Studies to explore the geographical and geopolitical imaginations of subaltern subjects and groups. Such writings have deployed subalternity to designate a substantive subject or group marginalized in the face of power. Departing from this, the paper instead treats subalternity more figuratively, as a word able to evoke spatialities occluded by the Euro-American power that haunts disciplinary geography. The paper argues that using subalternity like this holds the potential to pluralize geographical interventions, particularly in the light of the discipline's materialist turns since the late 1990s. To make this argument, the paper engages Gayatri Spivak's seminal critique of the Subaltern Studies collective, suggesting how this might speak productively to a postcolonial geographical methodology. It demonstrates the potential of this methodology by weaving it through a broader attempt to critically engage the politics of nature and environment in Sri Lanka

Evidence That Mutation Is Universally Biased towards AT in Bacteria

Mutation is the engine that drives evolution and adaptation forward in that it generates the variation on which natural selection acts. Mutation is a random process that nevertheless occurs according to certain biases. Elucidating mutational biases and the way they vary across species and within genomes is crucial to understanding evolution and adaptation. Here we demonstrate that clonal pathogens that evolve under severely relaxed selection are uniquely suitable for studying mutational biases in bacteria. We estimate mutational patterns using sequence datasets from five such clonal pathogens belonging to four diverse bacterial clades that span most of the range of genomic nucleotide content. We demonstrate that across different types of sites and in all four clades mutation is consistently biased towards AT. This is true even in clades that have high genomic GC content. In all studied cases the mutational bias towards AT is primarily due to the high rate of C/G to T/A transitions. These results suggest that bacterial mutational biases are far less variable than previously thought. They further demonstrate that variation in nucleotide content cannot stem entirely from variation in mutational biases and that natural selection and/or a natural selection-like process such as biased gene conversion strongly affect nucleotide content
