Determinants of the choice of health care facility utilised by individuals in HIV/AIDS-affected households in the Free State province of South Africa

This paper analyses differences in the choice of health care facility by individuals in HIV/AIDS-affected households in the Free State province of South Africa. Illness is more prevalent and severe amongst poorer affected households. The probability that individuals seek private versus public health care conditional on individual and household specific socio-economic variables is investigated. Significant determinants of choice of health care facility are income, severity of illness, the burden of illness and death in the household, the number of people in the household with access to medical aid, and secondary education. The demand for private health care over public health care is sensitive to income, with those from the lowest income quintile on average being less likely to switch to private health care than those in the highest income quintile. The planned roll-out of anti-retroviral treatment in public health care facilities in South Africa therefore will be crucial in enabling infected persons from poor households access to treatment. The provision of free treatment at public facilities may also see health care shift from private to public providers in the longer term.

Marketable Wealth in a Poor African Country

The study uses an asset index of consumer durables to track changes in household wealth in Ghana during the recent period of strong growth. Using the Ghana Living Standards Survey of 1998 that contains both wealth data and consumer durable data, the authors demonstrate that the asset index approximate marketable wealth adequately. Although asset index estimates of wealth cannot match the precision of wealth surveys,this approach can provide useful information on marketable wealth in countries where more appropriate sources are not available. The asset index analysis with the three demographic and health surveys for 1993, 1998 and 2003 suggests that the solid economic growth seen over this period has been accompanied by a strong rise in the average asset index scores.wealth, Ghana, asset index

Trends in Poverty and Inequality in Seven African Countries

This paper aims to analyse trends in poverty and inequality in seven African countries using an asset index constructed from comparable, nationally representative surveys using multiple correspondence analysis. Improvements in the asset index are largely driven by progress in the accumulation of private assets, while access to public services has deteriorated. Continued efforts at the expansion of access to public services such as waterborne sanitation and piped water, particularly in rural areas, are thus required. Overall poverty has declined in five of the seven countries. The trends in urban and rural poverty for the most part mirror these trends in overall poverty. Five of the seven countries experienced an improvement in overall inequality. Only in Zambia has overall inequality increased. Experiences in regards to trends in urban and rural inequality are mixed. These results, however, should be interpreted with caution, given the various conceptual and methodological limitations of the asset index approach to poverty analysis.Poverty, inequality, asset index, multiple correspondence analysis, Africa

Ruthenium complexes with lumazine derivatives: structural, electrochemical, computational and radical scavenging studies

In this research study, the formation and characterization of new ruthenium(II) and (III) complexes encompassing multidentate ligands derived from 6-acetyl-1,3, 7-trimethyllumazine (almz) are reported. The 1:1 molar coordination reactions of trans-[RuCl2(PPh3)3] with N-1-[1,3, 7-trimethyllumazine]benzohydride (bzlmz) and 6-(N-methyloxime)- 1,3,7-trimethyllumazine (ohlmz) formed a diamagnetic ruthenium(II) complex, cis-[RuCl2(bzlmz)(PPh3)] (1), and paramagnetic complex, cis-[RuIIICl2(olmz)(PPh3)] (2) [Holmz = 6-(N-hydroxy-N0-methylamino)-1,3,7-trimethyllumazine], respectively. These ruthenium complexes were characterized via physico-chemical and spectroscopic methods. Structural elucidations of the metal complexes were confirmed using single crystal X-ray analysis. The redox properties of the metal complexes were investigated via cyclic voltammetry. Electron spin resonance spectroscopy confirmed the presence of a paramagnetic metal centre in 2. The radical scavenging activities of the metal complexes were explored towards the DPPH and NO radicals. Quantum calculations at the density functional theory level provided insight into the interpretation of the IR and UV–Vis experimental spectra of 1

Coordination of di- and triimine ligands at ruthenium(II) and ruthenium(III) centers: structural, electrochemical and radical scavenging studies

Herein, we explore the coordination of di- and triimine chelators at ruthenium(II) and ruthenium(III) centers. The reactions of 2,6-bis-((4- tetrahydropyranimino)methyl)pyridine (thppy), N1,N2-bis((3-chromone) methylene)benzene-1,2-diamine (chb), and tris-((1H-pyrrol-2-ylmethylene) ethane)amine (H3pym) with trans-[RuIICl2(PPh3)3] afforded the diamagnetic ruthenium(II) complex cis-[RuCl2(thppy)(PPh3)] (1) and the paramagnetic complexes [mer-Ru2(μ-chb)Cl6(PPh3)2] (2), and [Ru(pym)] (3), respectively. The complexes were characterized by IR, NMR, and UV–vis spectroscopy and molar conductivity measurements. The structures were confirmed by single crystal X-ray diffraction studies. The redox properties of the metal complexes were probed via cyclic- and squarewave voltammetry. Finally, the radical scavenging capabilities of the metal complexes towards the NO and 2,2-di(4-tert-octylphenyl)-1-picrylhydrazyl (DPPH) radicals were investigate
