Changes in the South African media and management environment have had distinct influences on especially small to medium-sized mainstream media enterprises (media SMEs) which often have to compete with bigger media organisations for the same news stories. Moreover, these media organisations are commonly faced with unique challenges related to human and other resources. This situation adds to the importance of effective and efficient management practices at these media sites. The management practices of first-line news managers in media SMEs are qualitatively and quantitatively evaluated in this paper by considering six managerial competencies found in general management theory. These competencies relate to communication, planning and administration, teamwork; strategic action, global awareness and self-management.

This article draws on results of the South African National Editors' Forum (Sanef) journalism skills audit conducted in 2002. The research purpose was to conduct a national situation analysis of journalism skills among reporters. The research followed Sanef's continuing efforts to re-position journalism skills training at tertiary level. Results reveal a lack of reporting, writing and accuracy skills among reporters, highlighted both by reporters themselves, and news editors' evaluation of these skills.

The somatic form of angiotensin converting enzyme is a class I ectoenzyme that is bound to the surface of endothelial calls. It consists of two homologous, catalytic domains of approximately 600 residues each; a juxtamembrane "stalk" region; a transmembrane, hydrophobic sequence; and a 30 residue, C-terminal cytosolic domain. We have used limited proteolysis to probe the structural and functional properties of the enzyme. Endoproteinase Asp-N cleaves both the Thr615-Asp616 and the Leu1219-Asp1220 peptide bonds to generate the two catalytic domains which were isolated by a combination of immunoaffinity and lisinopril Sepharose affinity chromatography. The enzymatic characteristics of the N and C fragments were examined with angiotensin I, hippuryl-His-Leu, and luteinizing hormone-releasing hormone and indicate that both fragments contain catalytically active sites that retain their individual functional integrity.

In the Western tradition of journalism, news and news values have come to be defined and identified according to the Anglo-American model. The typical tenets of news values are based on attributes such as timeliness, unexpectedness, predictability, proximity, and especially conflict and unusualness. To concerned governments, media researchers and others involved in the media, it often seemed as if events in the Third World, also in sub-Saharan Africa, could only become news in the Western media if conflict-orientated themes such as corruption, coups, political unrest and famine were the main course on the news menu. This has led to a hypothesis that social conflict is the dominant news factor. We do not argue that the media should not report on conflict, as different forms of conflict within a system can lead to the renewal of old norms or the creation of new ones. However, it is argued that the media, in practice, but also in terms of media policy, do not have to overemphasize conflict as such. To this end different models, amongst others a mediating model of news about conflict for regional newspapers, are discussed.Binne die Westerse joernalistieke tradisie word nuus en nuuswaardes gewoonlik binne die Anglo-Amerikaanse model gedefinieer. Tipiese nuuswaardes is elemente soos tydigheid, onverwagsheid, voorspelbaarheid en veral konflik en ongewoonheid. Die gevolg hiervan is dat dit wiI voorkom of gebeure in die Derde Wereld, ook in Afrika suid van die Sahara, net nu us kan word in die Westerse media as dit uit konflik-georienteerde temas soos korrupsie, staatsgrepe, politieke onrus en hongersnood bestaan. In hierdie artikel word nie geargumenteer dat die media nie oor konflik as sodanig behoort te berig nie, aangesien konflik tot die vernuwing van ou norme en die skepping van nuwes kan lei. Daar word egter geargumenteer dat die media nie konflik hoef oor te beklemtoon nie. Ter iIlustrasie word 'n aantal nuusmodelle, o.m. 'n medierende nuusmodel m.b.t. konflik vir streek-of plaaslike koerante, bespreek.
