Abstract. The operations needed to decarbonize our energy systems increasingly involve faulted rocks in the subsurface. To manage the technical challenges presented by these rocks and the justifiable public concern over induced seismicity, we need to assess the risks. Widely used measures for fault stability, including slip and dilation tendency and fracture susceptibility, can be combined with response surface methodology from engineering and Monte Carlo simulations to produce statistically viable ensembles for the analysis of probability. In this paper, we describe the implementation of this approach using custom-built open-source Python code (pfs – probability of fault slip). The technique is then illustrated using two synthetic examples and two case studies drawn from active or potential sites for geothermal energy in the UK and discussed in the light of induced seismicity focal mechanisms. The analysis of probability highlights key gaps in our knowledge of the stress field, fluid pressures, and rock properties. Scope exists to develop, integrate, and exploit citizen science projects to generate more and better data and simultaneously include the public in the necessary discussions about hazard and risk.

Deep Geothermal Energy

Deep geothermal energy sources harvested by circulating fluids in engineered geothermal energy systems can be a solution for diesel-based northern Canadian communities. However, poor knowledge of relevant geology and thermo-hydro-mechanical data introduces significant uncertainty in numerical simulations. Here, a first-order assessment was undertaken following a “what-if” approach to help design an engineered geothermal energy system for each of the uncertain scenarios. Each possibility meets the thermal energy needs of the community, keeping the water losses, the reservoir flow impedance and the thermal drawdown within predefined targets. Additionally, the levelized cost of energy was evaluated using the Monte Carlo method to deal with the uncertainty of the inputs and assess their influence on the output response. Hydraulically stimulated geothermal reservoirs of potential commercial interest were simulated in this work. In fact, the probability of providing heating energy at a lower cost than the business-as-usual scenario with oil furnaces ranges between 8 and 92%. Although the results of this work are speculative and subject to uncertainty, geothermal energy seems a potentially viable alternative solution to help in the energy transition of remote northern communities.

I am pleased to publish an open-access online preprint of two articles and a research note that will appear in the forthcoming issue of the Journal of Contemporary Antisemitism 3, no. 2 (Fall 2020). This preprint is a new and exciting development for the Journal. It has been made possible by the generous donations from sponsors, including BICOM's co-chairman, David Cohen, whose support for the work of the Journal allows for timely scholarly analysis to be put into the public sphere.

Ranked List

The planet is facing an anthropogenic mass extinction of wildlife, which will have a grave impact on the environment and humans. Widespread human action is needed to minimize the negative impact of humans on biodiversity and support the restoration of wildlife. In order to find effective ways to promote pro-nature conservation behaviours to the general population, there is a need to provide a list of behaviours which will have worthwhile ecological impact and are worth encouraging. In a novel collaboration between psychologists and ecologists, 70 experts from practical and academic conservation backgrounds were asked to review and rate 48 conservation related behaviours. According to their judgement, this short paper presents a ranked list of pro-nature conservation behaviours for the public in the UK and similar landscapes. This includes behaviours people can engage in in their homes, their gardens, on their land, and in their roles as citizens.

Experience Effect

This volume addresses the relationship between archaeologists and the dead, through the many dimensions of their relationships: in the field (through practical and legal issues), in the lab (through their analysis and interpretation), and in their written, visual and exhibitionary practice--disseminated to a variety of academic and public audiences. Written from a variety of perspectives, its authors address the experience, effect, ethical considerations, and cultural politics of working with mortuary archaeology. Whilst some papers reflect institutional or organizational approaches, others are more personal in their view: creating exciting and frank insights into contemporary issues that have hitherto often remained "unspoken" among the discipline. Reframing funerary archaeologists as "death-workers" of a kind, the contributors reflect on their own experience to provide both guidance and inspiration to future practitioners, arguing strongly that we have a central role to play in engaging the public with themes of mortality and commemoration, through the lens of the past. Spurred by the recent debates in the UK, papers from Scandinavia, Austria, Italy, the US, and the mid-Atlantic, frame these issues within a much wider international context that highlights the importance of cultural and historical context in which this work takes place.

Male-factor infertility is a common but stigmatised issue, and men often do not receive the emotional support and the information they need. This study sought to understand awareness of male fertility issues compared to female fertility among the UK general male public, and also what were perceived as being the optimum methods for providing support for affected men, emotionally and through information. Men feel that male infertility is not discussed by the public as much as female infertility. Lifestyle issues that affect male fertility are not well understood, and men affected by infertility desire more support, including online, from health professionals and through peer support. Health professionals, including those in public health, could offer evidence-based programmes to reduce stigma and increase public knowledge about infertility, as well as offer emotional support to men with infertility problems.
