Science, Technology, and Public Policy

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

Technological innovation and widespread deployment of clean-energy technologies in emerging economies are critical for a global clean energy transition. Success or failure in this endeavour will have long-term energy and carbon consequences. A fundamental question exists about whether, and how, emerging economies can accelerate clean-energy transitions, given the unprecedented scales of their impending socio-economic and infrastructure transitions, and often-underdeveloped technological innovation capabilities and supporting finances. 

The authors examine the impact of the US Advanced Research Projects Agency-Energy (ARPA-E) on two outcomes for startup companies: innovation (measured by patenting activity) and business success (measured by venture capital funding raised, survival, and acquisition or initial public offering).

This paper examines a recent, rapid, and ongoing transition of India's lighting market to light emitting diode (LED) technology, from a negligible market share to LEDs becoming the dominant lighting products within five years, despite the country's otherwise limited visibility in the global solid-state lighting industry.

The study of existential risk — the risk of human extinction or the collapse of human civilization — has only recently emerged as an integrated field of research, and yet an overwhelming volume of relevant research has already been published. To provide an evidence base for policy and risk analysis, this research should be systematically reviewed. In a systematic review, one of many time-consuming tasks is to read the titles and abstracts of research publications, to see if they meet the inclusion criteria. The authors show how this task can be shared between multiple people (using crowdsourcing) and partially automated (using machine learning), as methods of handling an overwhelming volume of research.

The arguments in favor of the United States' declaring that the only purpose of its nuclear weapons is to deter others who possess them from using theirs — in other words, that in no circumstances will this country use nuclear weapons first — are far stronger than the arguments against this stance. It must be hoped that the next US administration will take this no-first-use step promptly.
