    Abstract This work investigates the convergence dynamics of a numerical scheme employed for the approximation and solution of the Frank-Kamenetskii partial differential equation. A framework for computing the critical Frank-Kamenetskii parameter to arbitrary accuracy is presented and used in the subsequent numerical simulations. The numerical method employed is a Crank-Nicolson type implicit scheme coupled with a fourth order spatial discretisation as well as a Newton-Raphson update step which allows for the nonlinear source term to be treated implicitly. This numerical implementation allows for the analysis of the convergence of the transient solution toward the steady-state solution. The choice of termination criteria, numerically dictating this convergence, is interrogated and it is found that the traditional choice for termination is insufficient in the case of the Frank-Kamenetskii partial differential equation which exhibits slow transience as the solution approaches the steady-state. Four measures of convergence are proposed, compared and discussed herein.

    Abstract Abusive practices in elite women's artistic gymnastics (WAG) have been the focus of discussions about how to eliminate or reduce them. Both coaches and parents have been named as key actors in bringing about change. Our focus is on parents and their ability to safeguard their daughters in WAG. Parents are not independent actors, however, but are part of a larger web consisting of an entanglement of emotions and technologies and rationalities used by staff, other parents, and athletes, bounded by skill development plans and by coaching expertise and authority. This entanglement may limit the ability of parents to bring about change. We draw on a Deleuzian notion of assemblage, Foucauldian concepts of discourse and governmentality and Ahmed's assertion about the entanglement of discourses and emotions to explore how parents are disciplined into accepting dominant discursive practices of sport clubs for elite athletes. The data were drawn from a project called the Parental Awareness Program (PAP) that was designed to make parents aware of practices in competitive WAG that may not be in their child's best interest. Participants were parents of young gymnasts who had been identified as "talented" and who were members of an elite gymnastics club. The data analysis was based on focus group discussions with a total of 22 parents and semi-structured interviews with 8 parents. The results suggested that although parents problematized many practices during PAP, processes of governmentality involving an assemblage of discourses about coaching expertise, families, talent, enjoyment, long term skill development plans and its associated time demands, together ensured parental consent for dominant practices. The data suggested that a reduction of abusive practices lies in part in critical examinations of skill development plans that are presented as regimes of truth and are kept in place by emotions and the authority accorded to coaching expertise. These processes curtail parents in their ability to safeguard what is in the best pedagogical interest of their daughter.

    Abstract Pantopaque was an oil-based positive contrast media used in central nervous system imaging before the use of water-soluble contrast agents. It is no longer used due to side effects, including arachnoiditis. Prior studies have indicated that remnants of pantopaque can be seen in modern radiographic imaging, including CT and MRI. With its use obsolete, these remnants have been increasingly mislabeled from "tumor" to "shot gun pellets". An understanding of this historic modality will usually lead to the correct diagnosis.

    Abstract The fight or flight phenomena is of evolutionary origin and responsible for the type of defensive behaviours enacted, when in the face of threat. This review attempts to draw the link between fear and aggression as behavioural motivations for fight or flight defensive behaviours. Hence, this review intends to examine whether fight or flight behavioural responses are the result of fear and aggression. Furthermore, this review investigates whether human biological motion captures the affective states associated with the fight or flight phenomenon. This review also aims to investigate how threat informed emotion and motor systems have the potential to result in empathetic appraisal modulation. This is of interest to this systematic review, as empathetic modulation is crucial to prosocial drive, which has the potential to increase the inclination of alleviating the perceived threat of another. Hence, this review investigates the role of affective computing in capturing the potential outcome of empathy from threat perception. To gain a comprehensive understanding of the affective states and biological motion evoked from threat scenarios, affective computing methods used to capture these behavioural responses are discussed. A systematic review using Google Scholar and Web of Science was conducted as of 2023, and findings were supplemented by bibliographies of key articles. A total of 22 studies were analysed from initial web searches to explore the topics of empathy, threat perception, fight or flight, fear, aggression, and human motion. Relationships between affective states (fear, aggression) and corresponding motor defensive behaviours (fight or flight) were examined within threat scenarios, and whether existing affective computing methods are succinct in capturing these responses, identifying the varying consensus in the literature, challenges, and limitations of existing research.
