Thermodynamic Geometry and Critical Behavior of Black Holes

Based on the observations that there exists an analogy between the Reissner-Nordstr\"om-anti-de Sitter (RN-AdS) black holes and the van der Waals-Maxwell liquid-gas system, in which a correspondence of variables is $(\phi, q) \leftrightarrow (V,P)$, we study the Ruppeiner geometry, defined as Hessian matrix of black hole entropy with respect to the internal energy (not the mass) of black hole and electric potential (angular velocity), for the RN, Kerr and RN-AdS black holes. It is found that the geometry is curved and the scalar curvature goes to negative infinity at the Davies' phase transition point for the RN and Kerr black holes. Our result for the RN-AdS black holes is also in good agreement with the one about phase transition and its critical behavior in the literature.Comment: Revtex, 18 pages including 4 figure

Autistic adults' experiences of financial wellbeing: Part II

Financial wellbeing is an important component of people’s overall wellbeing, reflecting the capacity to live a comfortable and fulfilling life. Yet virtually nothing is known about this topic for autistic people. This study addressed this gap using a two-phase sequential mixed-methods design. Here, we report on findings from the Phase 2 qualitative study. In this study, 21 autistic participants were purposively selected based on the status of their financial wellbeing, including 12 people with high, and 9 with low, financial wellbeing, and interviewed by an autistic researcher. We identified four themes through reflective thematic analysis. Having access to a stable income made an enormous difference to people’s financial wellbeing. Participants emphasised how their broader social supports, especially family support, shaped their financial wellbeing. Yet, planning financially was often challenging, especially for people who had insufficient money to meet their basic needs. Nevertheless, our participants reported a strong drive to stay in control and avoid unnecessary risk. Our findings revealed how much money matters in autistic people’s lives. Future research should investigate the ways in which autistic people could secure more reliable incomes and identify the most effective ways to support them to achieve financial resilience

Predicting the financial wellbeing of autistic adults: Part I

Many autistic adults are likely to experience poor financial wellbeing and hardship due to unemployment and under-employment. Research in the general population demonstrates that subjective financial wellbeing—how people perceive their financial situation—influences quality of life. There is no research, however, examining the subjective financial wellbeing of autistic people. This study therefore aimed to (1) understand the subjective financial wellbeing of a sample of autistic adults living in Australia compared to a general Australian population sample and (2) identify the predictors of subjective financial wellbeing in this sample of autistic adults. To this end, 191 autistic adults aged 18–83 years (mean = 39.28, standard deviation = 11.74) completed an online survey about their economic status, financial wellbeing, financial behaviors, confidence in money management skills, and anxiety and depression symptoms. Almost half of our sample felt it was a struggle to make ends meet, whereas only one-third of the general Australian population felt this way. Similar to the general population, autistic people’s income and their financial behaviors (specifically, saving and not borrowing for everyday expenses) predicted their sense of financial wellbeing. Our findings have implications for both research and practice. Lay abstract: Researchers have found the way people feel about their financial situation is related to their quality of life. We know that many autistic people find it hard to find a job. And for those autistic people who have a job, they are often underpaid. Not having a job or being underpaid often means having low income. Having low income is likely to influence how autistic people feel about their financial situation. However, no research has looked at these issues for autistic people. This is the first study that helps us learn more about what autistic adults think about their financial situation. We looked at autistic people’s thoughts on this issue compared to people from the general Australian population. We also looked at what things might impact how autistic people feel about their financial situation—which might be how much money they earn, what they do with that money, and their mental health. Many autistic adults felt they were struggling with financial wellbeing and this was connected both to the level of their income and how they said they managed their money. Those who were able to save and not borrow for everyday expenses reported feeling a greater sense of financial wellbeing. Concrete changes might help to improve autistic people’s financial wellbeing. We need to investigate how we can help autistic people find and keep well-paying jobs. And we need to work out the best ways of equipping autistic people with the skills they need in financial matters

Research summary: Anxiety and Depression from Adolescence to Old Age in Autism Spectrum Disorder

[Excerpt] Our team recently published a journal article reporting on a study that looked at the relationship between anxiety and depression, age, sex (male, female), and autism symptoms in autistic adults. So far there has been little research into mental health challenges such as anxiety and depression across the lifespan of autistic individuals. To inform and provide appropriate supports we need to better understand the challenges experienced by autistic individuals and looking at mental health across the lifespan can help us do that. It is also important to understand what factors can be related to good and poor mental health, so we can investigate that relationship and understand it
