South Africa: The Ambiguities of a Middle Power
Global Policy, EarlyView.ABSTRACT South Africa represents an interesting species of a middle power. This derives from its inherited economic muscle as Africa's powerhouse and the liberation struggle against apartheid, both of which have shaped its democratic transition. The traditions of liberation and democracy, in turn, have profoundly influenced how South Africa has ...

Rise of the south: How Arab‐led maritime trade transformed China, 671–1371 CE
Asia‐Pacific Economic History Review, Volume 65, Issue 1, Page 3-38, March 2025.Abstract China's center of socioeconomic activities was in the North prior to the Tang dynasty but is in the South today. We demonstrate that Arab and Persian Muslim traders triggered that transition when they came to China in the late seventh century, by lifting maritime trade along the South Coast and re‐creating the South.

The 2023 Flight of the Faint Intergalactic-medium Redshifted Emission Balloon
The Astrophysical Journal Supplement SeriesThe second iteration of the Faint Intergalactic-medium Redshifted Emission Balloon (FIREBall-2) is a UV multiobject spectrograph designed to detect emission from the circumgalactic and circumquasar medium at low redshifts ( z < 1).

Autonomous spectrographic system to analyse the main elements of fireballs and meteors
Earth, Planets and Space, 2018 We present a meteor observation system based on imaging CCD cameras, wide-field optics and a diffraction grating. This system is composed of two independent spectrographs with different configurations, which allows us to capture images of fireballs and ...

Writing about a Prime Minster: Reflections on How Malcom Fraser PM Happened
Australian Journal of Politics &History, EarlyView.In 1989 I publsihed Malcolm Fraser PM, a study of the way that prime minister Fraser worked. In this note I muse about the back story, about the processes involved in writing a study of a recently defeated prime minster, explaining how the book was written and waht could be learnt from the interactions with Fraser.

Creativity and Innovation Management, EarlyView.ABSTRACT This paper explores the limits of mission‐directed entrepreneurial states by drawing on the theory of recombinant innovation and F.A. Hayek's insights on the spontaneous growth of knowledge in society. First, the use of discretionary policymaking curtails the range of knowledge generated in the process of social interaction, limiting the scope

Resonances and fluctuations in the statistical model
EPJ Web of Conferences, 2012 We describe how the study of resonances and fluctuations can help constrain the thermal and chemical freezeout properties of the fireball created in heavy ion collisions. This review is based on [1–5]

Measurements of fireball onset
Physics of Plasmas, 2018 Laser-based measurements of the characteristic features of fireball onset and stabilization in response to a stepped voltage applied to an anode immersed in a low pressure (100 mTorr) helium afterglow are reported. These include spatial and temporal evolution of metastable species, electron density, and electric field magnitude as measured by planar ...
