In July 2014, Sweden’s full crisis response system engaged in a major operation as a small forest fire spun out of control, turning into the largest forest fire in Sweden in modern times. A number of investigations have been undertaken to understand the course of the fire and identify lessons for future crisis management. This paper presents one approach to identifying such lessons, the lessons...

Dark matter is presumably made of some new, exotic particle that appears in extensions of the Standard Model. After giving a brief overview of some popular candidates, I discuss in more detail the most appealing case of the supersymmetric neutralino.

Social law is perceived as evolving through the competition of individual social strategies held by the agents. A strategy with strong authority, accepted by many agents, will tend to diffuse to the remaining agents. The authority of a social strategy is determined by not only the number of but also the collective social positions of its overlaid agents. This paper presents a novel collective s...

War-fighting and selection-effects explanation were compared to explain why democracies were more likely to win wars. An analysis of all interstate wars between 1816 and 1982 revealed that democracies that initiate wars often win them. Results also suggest that domestic political structure ...

Global fits to precision cosmological data which show that there is a dark energy component comprising about 2/3 of the total cosmological energy also hint that a dark energy with w = P/ρ < −1 is viable, even favored. Here we discuss implications of such a surprising w, including whether it jeopardizes vacuum stability. It appears to be secure in microscopic processes, but why bulk dark energy ...

Investors significantly reduce their future returns by selecting mutual funds with higher fees, allured by higher past returns that do not predict future performance. This suboptimal behavior, which can roughly halve an investor’s retirement savings, is driven by two psychological factors. One factor is difficulty comprehending rate information, which is critical given that mutual fund fees and...
