Subcritical coal in Australia: risks to investors and implications for policymakers

This paper locates subcritical coal-fired power stations in Australia and identified the ones most at risk of stranding due to their carbon intensity and local environmental impacts. The research shows which companies own these assets in Australia and ranks companies by exposure. In addition, we examine the implications of subcritical coal for Australian policymakers, in particular we look at the the costs, benefits, and mechanisms for phasing out subcritical coal in Australia

The role of skills: from worklessness to sustainable employment with progression : UK Commission for Employment and Skills Evidence Report no. 38

This study is shaped by the recognition that while there has been a great deal of policy development around the transition from unemployment and inactivity to employment over the last decade, policy can still be informed about how best to nurture sustainable employment for those at risk of labour market exclusion. There remain challenges associated with, for example, the cost-effectiveness of intervention, the „low pay no pay‟ cycle and access to training. As a consequence, the opportunities for sustainable progression, upward social mobility and alleviating poverty remain unrealised for many workers in lower paid occupations. The methodology underpinning this study is predominantly based on a literature search and review of the research and evidence base post 2005. This is supplemented with the development of four international case studies (Australia, Denmark, Germany, United States contained in a separate annex) and an e-consultation with country experts

SIMPEL: Circuit model for photonic spike processing laser neurons

We propose an equivalent circuit model for photonic spike processing laser neurons with an embedded saturable absorber---a simulation model for photonic excitable lasers (SIMPEL). We show that by mapping the laser neuron rate equations into a circuit model, SPICE analysis can be used as an efficient and accurate engine for numerical calculations, capable of generalization to a variety of different laser neuron types found in literature. The development of this model parallels the Hodgkin--Huxley model of neuron biophysics, a circuit framework which brought efficiency, modularity, and generalizability to the study of neural dynamics. We employ the model to study various signal-processing effects such as excitability with excitatory and inhibitory pulses, binary all-or-nothing response, and bistable dynamics.Comment: 16 pages, 7 figure

The role of skills from worklessness to sustainable employment with progression

This study is shaped by the recognition that while there has been a great deal of policy development around the transition from unemployment and inactivity to employment over the last decade, policy has not been sufficiently informed about how best to nurture sustainable employment for those at risk of labour market exclusion. The review focused on evidence from 2005: it provides a review of data, UK and international literature and, incorporates findings from four international case studies ( Australia, Germany, Denmark and the United States. The report provides an overview of the economic context for low pay and low skilled work and highlights the need for a continuing commitment to promoting opportunities in the labour market as a means of progression and alleviating poverty and encouraging social mobility. The report argues that there is an inextricable link between skills and ‘better jobs’. The authors conclude that a long-term view is required to decide how best to support someone at the point of worklessness: to address employability barriers in the short-term; and prepare the individual to retain, and progress in, employment. The concept of career is explored as a framework for progression: a combination of career guidance, a career / personal development plan and career management skills are identified as tools to raise aspiration and enable individual’s to take action once they are in work to support their own progression. Thinking about the workplace, the report reviews the evidence on the role of job design, line management and progression pathways in facilitating workplace learning as a route to progression

Low regularity solutions for the general Quasilinear ultrahyperbolic Schr\"odinger equation

We present a novel method for establishing large data local well-posedness in low regularity Sobolev spaces for general quasilinear Schr\"odinger equations with non-degenerate and nontrapping metrics. Our result represents a definitive improvement over the landmark results of Kenig, Ponce, Rolvung and Vega, as it weakens the regularity and decay assumptions to the same scale of spaces considered by Marzuola, Metcalfe, and Tataru, but removes the uniform ellipticity assumption on the metric from their result. Our method has the additional benefit of being relatively simple but also very robust. In particular, it only relies on the use of pseudodifferential calculus for classical symbols.Comment: 52 page
