Truth and Reconciliation in South Africa: Jewish Voices and Perspectives
No full textThe author who served on the South African� Truth� and Reconciliation Commission (TRC) focuses on the Jewish experience in South Africa� during� the apartheid years. At a special TRC Hearing for Faith Communities (East London, 17-19� November 1997) Chief Rabbi Cyril Harris submitted a statement on behalf of his community. Two earlier documents were also put at� the TRC�s disposal: a statement on Reconciliation� presented by Gesher (a Jewish movement for social action) as a well as a comprehensive volume containing 27 interviews with Jewish activists (Cutting Through the Mountain). Taking his cue from both the Chief Rabbi�s presentation and the earlier documents, the author discusses the role of the Jewish community in overtly and covertly supporting the apartheid regime, as well the experiences of many Jews in struggling against apartheid. Finally the contribution of the Jewish community towards healing and reconciliation in South Africa comes under the spotlight
Truth and Reconciliation in South Africa: the role of the faith communities
No full textTen years after the South African Truth and Reconciliation Commission commenced with its work (1995), the author � using the statements made by representatives of the different faith communities in South Africa � analyses the role the communities played in the past: as agents of oppression, as victims of apartheid, as opponents of apartheid, as well as their role in the country�s transition to a new democratic society. Finally, the contribution of the faith communities in the process of reconciliation and nation building is discussed
Leadership for reconciliation: A Truth and Reconciliation Commission perspective
No full textAs important as the need for authentic leadership in the fields of politics, economy and education in Africa may be, the continent is also in dire need of leadership for reconciliation. Against the backdrop of the South African Truth and Reconciliation Commission (TRC), the author � who served on the Commission � discusses five characteristics of leaders for reconciliation. Leaders need to be: leaders with a clear understanding of the issues at stake; leaders with respect for the truth; leaders with a sense of justice; leaders with a comprehension of the dynamics of forgiveness; and leaders with a firm commitment. The insights and experiences of both the chairperson of the TRC, Desmond Tutu, and the deputy chair, Alex Boraine, form the backbone of the article

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Inhibition of monoamine oxidase by 3,4-dihydro-2(1H)-quinolinone derivatives
No full textIn the present study, a series of 3,4-dihydro-2(1H)-quinolinone derivatives were synthesized and evaluated
as inhibitors of recombinant human monoamine oxidase (MAO) A and B. The 3,4-dihydro-2(1H)-
quinolinone derivatives are structurally related to a series of coumarin (1-benzopyran-2-one) derivatives
which have been reported to act as MAO-B inhibitors. The results document that the quinolinones are
highly potent and selective MAO-B inhibitors with most homologues exhibiting IC50 values in the nanomolar
range. The most potent MAO-B inhibitor, 7-(3-bromobenzyloxy)-3,4-dihydro-2(1H)-quinolinone,
exhibits an IC50 value of 2.9 nM with a 2750-fold selectivity for MAO-B over the MAO-A isoform. An analysis
of the structure–activity relationships for MAO-B inhibition shows that substitution on the C7 position
of the 3,4-dihydro-2(1H)-quinolinone scaffold leads to significantly more potent inhibition
compared to substitution on C6. In this regard, a benzyloxy substituent on C7 is more favourable than
phenylethoxy and phenylpropoxy substitution on this position. It may be concluded that C7-substituted
3,4-dihydro-2(1H)-quinolinones are promising leads for the therapy of Parkinson’s disease
A Review of the Pharmacological Properties of 3,4-dihydro-2(1H)- quinolinones
No full textThe 3,4-dihydro-2(1H)-quinolinone moiety is present in a number of pharmacologically active compounds. These include FDA approved drugs such as cilostazol, carteolol and aripiprazole as well as numerous experimental compounds. Compounds containing the 3,4-dihydro-2(1H)-quinolinone moiety also exhibit a variety of activities in both the peripheral and central tissues, which includes phosphodiesterase inhibition, blocking of β-adrenergic receptors, antagonism of vasopressin receptors and interaction with serotonin and dopamine receptors. Based on its versatility in drug design and action, this paper reviews the pharmacological actions of compounds containing the 3,4-dihydro-2(1H)- quinolinone scaffold with emphasis being placed on the most important and significant members of each activity clas
Mineral Sciences Building (photos 1)
No full textColoured digital photo created using Luminix digital camera, size 2048 * 1360 pixels, 551 kilobytes.Built in a simple style, the building reflects elements of the Little Brazilian or Modern Brazilian style and has a light green and white terrazzo cover and diamond-shaped windows adorning the two entrances. Initially known as the Third Mathematics and Sciences building, it was designed by architects A L Meiring and P R Nel, and was inaugurated on 3 May 1955. It was designed to form part of the inner court of the university. An identical building was planned to the south of the Engineering Tower to ensure the building would not clash with any future buildings. In the 1980s various departments were relocated resulting in the natural convergence of all the earth sciences departments into the same building, after which the name was changed to the Mineral Sciences building
