The 'new beginning' : the Italian Communist Party under Achille Occhetto (1990)
Journal Article
Bull, M., & Daniels, P. (1990). The 'new beginning' : the Italian Communist Party under Achille Occhetto. Journal of Communist Studies and Transition Politics, 6(3), 22-43. https://doi.org/10.1080/13523279008415035

This article analyses the ongoing transformation of the Italian Communist Party into a non-communist party of the left under the leadership of Achille Occhetto following the collapse of communist regimes in central and eastern Europe. The article ana... Read More about The 'new beginning' : the Italian Communist Party under Achille Occhetto.

Risk-sensitive foraging in bitterlings Rhodeus sericus: effects of food requirement and breeding site quality (1990)
Journal Article
Young, R., Clayton, H., & Barnard, C. (1990). Risk-sensitive foraging in bitterlings Rhodeus sericus: effects of food requirement and breeding site quality. Animal Behaviour, 40(2), 288-297. https://doi.org/10.1016/S0003-3472%2805%2980923-6

Risk-sensitive foraging preferences in bitterlings were examined in relation to changing food deprivation and intake relative to estimated requirement. When running above estimated requirement and presented with a choice of constant and variable feed...

Spatial solitary-wave optical memory (1990)
Journal Article
Mcdonald, G., & Firth, W. (1990). Spatial solitary-wave optical memory. Journal of the Optical Society of America B, 7(7), 1328-1335. https://doi.org/10.1364/JOSAB.7.001328

We consider some features of spatial solitary-wave switching in a unidirectional ring cavity that is partially filled with a fast and saturably self-focusing nonlinear medium. Large (part-beam switched) solitary arrays are considered. It is found tha... Read More about Spatial solitary-wave optical memory.

The Barrack Street well: images of a Cape Town household in the nineteenth century (1990)
Journal Article
Hall, M., Halkett, D., Klose, J., Ritchie, G., & Poggenpoel, C. (1990). The Barrack Street well: images of a Cape Town household in the nineteenth century. South African archaeological bulletin, 45(152), 73-92

This paper describes the results of excavation of well deposits from Barrack Street, Cape Town. The sequence starts with an assemblage dated to the late eighteenth century and continues, with a clear stratigraphy, until the late nineteenth century. A...

A stone wall out of the earth that thundering cannon cannot destroy: bastion and moat at the Castle, Cape Town (1990)
Journal Article
Hall, M., Halkett, D., Vanbeek, P., & Klose, J. (1990). A stone wall out of the earth that thundering cannon cannot destroy: bastion and moat at the Castle, Cape Town. Social Dynamics, 16(1), 22-37. https://doi.org/10.1080/02533959008458483

Although the urgency with which the Dutch East India Company administration at the Cape built defensive works was a direct result of their fear of attack from both land and sea, there was an additional imperative, for the Castle at Cape Town stood as...

All-optical switching in a nonlinear resonator (1990)
Journal Article
Mcdonald, G., & Firth, W. (1990). All-optical switching in a nonlinear resonator. Journal of Modern Optics, 37(4), 613-626. https://doi.org/10.1080/09500349014550701

In this paper we consider some features of all-optical switching in a unidirectional ring cavity which is partially filled with a fast and saturably nonlinear medium. A comparative study of cross-talk for both signs of nonlinearity, in a two pixel (w... Read More about All-optical switching in a nonlinear resonator.
