It is well known that the world has become globalised due to growing economic, political, social and cultural integration and interdependence among states. Several kinds of cultural diffusions have contributed to this situation and to the five-fold expansion of the global economy in the last four decades. It could therefore be expected that the quality of life of especially the least industrialised nations in the world would have been improved. However, economic forces of globalisation are moving toward greater inequality among states. This has become at least one of the reasons why many people in Africa are experiencing severe poverty and live on less than one US dollar a day. In addition to poverty, various other negative factors contribute to the lack of sustainable development in Africa: a lack of competitiveness and democracy, high population growth, HIV/AIDS, deficient leadership and war.Using a functionalist conceptual model, the purpose of this article is to alialyse the said issues that inhibit sustainable development in primarily South Africa. Sustainable development means the fulfilment of the functions of adaptation, goal attainment, integration as well as pattern maintenance and tension management. The role that South Africa could play in the sustainable development of the Southern Africau Development Community (SADC) region will also be discussed.

J. Wu et al. -- 7 pags., 6 figs. ; The β-decay half-lives of 94 neutron-rich nuclei Cs144-151, Ba146-154, La148-156, Ce150-158, Pr153-160, Nd156-162, Pm159-163, Sm160-166, Eu161-168, Gd165-170, Tb166-172, Dy169-173, Ho172-175, and two isomeric states Er174m, Dy172m were measured at the Radioactive Isotope Beam Factory, providing a new experimental basis to test theoretical models. Strikingly large drops of β-decay half-lives are observed at neutron-number N=97 for Ce58, Pr59, Nd60, and Sm62, and N=105 for Eu63, Gd64, Tb65, and Dy66. Features in the data mirror the interplay between pairing effects and microscopic structure. r-process network calculations performed for a range of mass models and astrophysical conditions show that the 57 half-lives measured for the first time play an important role in shaping the abundance pattern of rare-earth elements in the solar system. ; This work was carried out at the RIBF operated by RIKEN Nishina Center, RIKEN and RCNP, Osaka University.
