Greening for Bosons

Throughout history, scientific advancement has been dependent upon advances in the technologies of research. However, branches of research that today rely on Research Infrastructures (RIs) such as accelerators require technological investments so large that multination collaborations are required to fund them. Modern accelerator science also has massive (and increasing) energy needs, yet the very provision of secure, equitable, clean and cost effective energy is one of the greatest sustainability challenges facing society. Modern energy provision systems are fundamental to development, yet also constitute one of the greatest threats to sustainability via their contribution to environmental degradation and climate change. This paper works from a premise that any new proposal for investment in an RI should credibly demonstrate that it would deliver more value than cost to society. As our understanding of the negative impacts of energy use grows, the demonstration of overall value creation has become more complex; it must now include consideration of an RI’s ‘energy system footprint’. Programs to reduce the energy footprint can help address this delicate balance. This paper uses experiences in the development of the European Spallation Source (ESS) in Sweden to demonstrate how credible programs to improve the energy performance of an RI can take form

Improved mutual fund investment choice architecture

Two choice architecture interventions were explored to debias investors’ irrational preference for mutual funds with high past returns rather than funds with low fees. A simple choice task was used involving a direct trade-off between maximizing past returns and minimizing fees. In the first intervention, warning investors that, “Some people invest based on past performance, but funds with low fees have the highest future results” was more effective than three other disclosure statements, including the US financial regulator’s, “Past performance does not guarantee future results”. The second intervention involved converting mutual fund annual percentage fees into a 10 year dollar cost equivalent. This intervention also improved investors’ fee sensitivity, and remained effective even as past returns increased. Financially literate participants were surprisingly more likely to irrationally maximize past returns in their investment choices

Girls get smart, boys get smug: Historical changes in gender differences in math, literacy, and academic social comparison and achievement

Girls’ lack of self-belief has frequently been cited as a major barrier to advancement in both empirical research and in the popular imagination. With girls now outcompeting boys at almost every educational level, this paper considers if girls still have lower self-concept than boys, if this changes when controlling for academic ability, and what mechanisms explain gender differences. We compare and contrast rational choice, contrast, and assimilation approaches to self-concept and juxtapose historical trajectories in gender differences in self-concept and achievement to distinguish between them. We do this in five age cohorts born between 1981 and 1993 (N = 66, 522) for math, literacy, and general academic domains. Results suggest that there are still significant differences in self-concept between equally able boys and girls and that a mix of assimilation and contrast mechanisms likely explains the size and direction of these effects
