Beyond the Dance: A look at Mbende (Jerusarema) Traditional Dance in Zimbabwe
Jesmael Mataga 국립민속박물관 2008 International Journal of Intangible Heritage Vol.3 No.-
Traditional dance occupies a pivotal place in the economic,political and socio-cultural system in African traditionalsociety. This role survives to the present day manifested inseveral performances that have stood the test of time andalien influences. Despite the onslaught of colonialism,Christianity and westernization, traditional dances havesurvived to this day, albeit with modifications. Mbende /Jerusarema in Zimbabwe is one dance that has withstoodthe test of time and western influence. It is an importantcultural expression which in 2005 was listed on theUNESCO Masterpieces of the Oral and Intangible heritageof humanity list, making it one of the few African culturalexpressions accorded such recognition. This paper looksinto the history of the dance, the material culture and theskills and know-how associated with the uniqueperformance. Observations in this paper were inspired bythe research carried out by the committee formed toprepare a nomination file for the Mbende dance to theUNESCO masterpieces list in 2003, of which I was amember
The Role of Vibrational Coherency in Ultrafast Reaction Dynamics of PYP
Chosrowjan, Haik,Mataga, Noboru,Taniguchi, Seiji,Shibata, Yutaka,Hamada, Norio,Tokunaga, Fumio,Imamoto, Yasushi,Kataoka, Mikio Korean Society of Photoscience 2002 Journal of Photosciences Vol.9 No.2
Coherent oscillations in is fluorescence dynamics of W.-t. PYP and its site-directed mutants have been observed. Two oscillatory modes coupled with the ultrafast fluorescence due to the twisting of the excited chromophore were identified, a high ftequency mode (∼135 cm$\^$-1/) with ∼550 is damping time and a low frequency overdamped mode (-45 cm$\^$-1/) with ∼250 is damping time, respectively. Both modes disappear in the fluorescence dynamics of denatured PYP emphasizing the important role of the protein nanospace as the environment for photoreaction. The qualitative picture of fluorescence dynamics in site-directed mutants was rather similar to that in W.-t. PYP, i.e., similar oscillatory modes (∼130-140 cm$\^$-1/ and ∼40-70 cm$\^$-1/) have been observed. This indicates that the vibrational modes and electron-vibration couplings do not change dramatically due to the mutation though the damping time of low frequency mode a little decreases as the protein nanospace structure becomes looser and more disordered by mutation. On the other hand, in the case of some PYP analogues, the qualitative picture of fluorescence dynamics changes, showing the familiar picture of solvation effect whereas the oscillations are almost damped. Comparative analyses of these observations are presented.
A FULL CHARGE SEPARATION OVER THE TWO SAME CHROMOPHORES IN A PHOTOSYNTHETIC TETRAD

The synthesis and excited-state dynamics are described for a tetrad (ZC - ZP - ZP - I) consisting of zinc chlorin (ZC), zinc porphyrin (ZP), zinc porphyrin (ZP), and pyromellitimide (I), which upon photoexcitation provides a fully charge-separated state (ZC$^+$- P - ZP - l$^- $) with lifetimes of 230 $\mu$s in THF and > 50$ \mu$s in DMF at room temperature via a stepwise electron-transfer relay that has been detected by the ps-time resolved transient absorption spectroscopy.
