Examination of Afghanistan's Development Traps

Regional Science Policy &Practice, EarlyView., 2022
Abstract We examine the factors behind Afghanistan's persistent underdevelopment. Drawing on various theories of development traps operating at the demographic, economic and institutional levels, we seek to assess whether and to what extent their functioning affects Afghanistan's development. To capture the functioning of development traps empirically,

How weather got its words: a history of meteorological English – Part 2: the scientific age and beyond

Weather, EarlyView.
The English language is a gargantuan, gluttonous beast. It has become extraordinary in its powers of assimilation – such that we rarely consider the origins of the words we use. In this paper, we will shed light on these origins, including the Pontic–Caspian steppe, the British Empire and, of course, a TV show.

Comparison of Dielectric Recovery After Arc Burning in SF6 Gas and Its Potential Alternatives

High Voltage, EarlyView.
ABSTRACT Although sulphur hexafluoride (SF6) exhibits exceptional insulating properties, it is a potent greenhouse gas. Therefore, studying alternatives to SF6 is critical for developing environmentally friendly high‐voltage electrical equipment.

The Impact of Various Contact Structures on the Microscopic Surface Condition of Vacuum Interrupters During Capacitive Switching

High Voltage, EarlyView.
ABSTRACT The double‐break vacuum circuit breakers (VCBs) that utilize series break technology effectively increase the switching capability for capacitive currents, elevate the withstand voltage level, and reduce the likelihood of restrike, all without compromising the breaking capacity for short‐circuit currents.

Temporary Employment and First‐Time Homeownership in Australia

Australian Economic Review, EarlyView.
ABSTRACT Research Questions How does temporary employment, that is, fixed‐term contract and casual employment, affect the transition into first‐time homeownership among young people in Australia? Does the effect differ by employment type, gender, relationship situation, or parents' socio‐economic status?
