- Description: The paper presents the results of preliminary investigations at Birnam, in the Rhodes area of the eastern Cape Drakensberg, which may have important implications for palaeoenvironmental reconstructions in Southern Africa. A study has been undertaken on a sedimentary sequence exposed by fluvial incision on the outer bend of the River Bokspruit, at an altitude of 1850 m.

Blanching activities of betamethasone 17-valerate formulations: effect of the dosage form on topical drug availability

- Description: The blanching activities of Betnovate© cream, lotion, ointment and scalp application (each containing 0.1 % betamethasone (as the 17-valerate)) were determined using healthy human subjects over a 32 h period in both the occludedand unoccluded modes. Considering that allfour formulation types contained the same label concentration of corticosteroid,it may bepresumed that theformulations would show similar topical drug availability: this was, however, not found to be the case. The scalp application demonstrated the highest topical availability in both the occluded and unoccluded modes. The lotion formulation showed the greatest increase in topical availability on occlusion and the ointment formulation was the least sensitive to the effects of occlusion. These differences, due solely to the effects of the vehicle, may have important clinical implications.

Cognitive therapy and the restructuring of early memories through guided imagery
- Authors: Edwards, David J A
- Date: 1990
- Language: English
- Type: Article
- Identifier: vital:6241 , http://hdl.handle.net/10962/d1007853
- Description: This article describes the application of a guided imagery psychodrama technique to emotionally charged early memories. Such memories provide access to core schemata about the self and social relationships. Two case studies illustrate how the imagery technique enables the therapist to identify and restructure key cognitions out of which the schemata are constructed. The need for techniques to modify developmentally primitive schemata is discussed. Examples are given of ways to assist the patient in confronting the strong affect that may be aroused and in dealing with cognitions that block the process. Effectiveness is discussed in terms of the contribution of a guided imagery session to the overall process of ''learning to learn'' that takes place in cognitive psychotherapy.

Cognitive-behavioral and existential-phenomenological approaches to therapy : complementary or conflicting paradigms?
- Authors: Edwards, David J A
- Date: 1990
- Language: English
- Type: Article
- Identifier: vital:6242 , http://hdl.handle.net/10962/d1007854
- Description: The relationship between the cognitive-behavioral and existential-phenomenological traditions in therapy is examined. While Beck cites phenomenological writers such as Heidegger, Husserl, and Binswanger, he does not initiate any dialogue with this tradition in depth. Parallels are drawn between the goals of psychotherapy as outlined by Rogers and goals identified in the contemporary cognitive-behavioral literature, between cognitive therapy's approach to clients' underlying assumptions and the phenomenological reduction as described by Husserl, and between a shared acceptance of the therapeutic use of the client-therapist interaction. While, in both approaches, therapists take on an educative role, in each approach a different aspect of the learning process is focused on. Phenomenological therapy's attitude to reality testing, the dangers of a directive stance by the therapist, the conflict between empathy and rational dialogue, and cognitive therapy's view of emotion are also discussed. The complementarity between the two approaches is emphasized and a continuing dialogue recommended.

The South African sugar industry

- Description: The sugar industry was established in Natal in the mid-nineteenth century. By the 1980s, South Africa produced c. 2 million metric tons of sugar per annum and, directly or indirectly, the industry supported almost one million people. Exports, which amounted for almost half the sugar produced in the 1970s, declined during the 1980s and low prices together with American and Canadian sanctions have forced the industry to consider alternative uses for sugar cane.
