Mau Maus of the mind: Making Mau Mau and remaking Kenya

African Studies Seminar series. Paper presented 1991?Why was Mau Mau believed to be so evil? The horror story of Britain's empire in the 1950s, it was less of a military threat but thought to be more atrocious than either the Malayan Communists or the Cypriot EOKA. The movement has lived in British memories as a symbol of African savagery, and modern Kenyans are divided by its images, militant nationalism or chauvinist thuggery. This essay explores some of these Mau Maus of the mind

African Studies, Europe and Africa

'Warum sehen die meisten Europäer 'Afrika' als ein hilfloses Opfer und 'den Westen' als einen Rettungsdienst? Inwieweit sind Afrikanisten für diese Missinterpretalion verantwortlich? Wie können wir dafür Sorge tragen, dass EU und G8 auf die Vorschläge der Commision for Africa reagieren? Inwieweit können wir auf unsere Vorgänger zurückblicken, um von ihnen zu lernen, wie man nicht Europa dazu drängt 'etwas zu machen', sondern den Afrikanern eine bessere Chance gibt, sich selbst zu helfen? Inwieweit könnten unsere eigenen Analysen der afrikanischen Gesellschaften, Okonomien und Politiken besser auf die Beantwortung der Fragen ausgerichtet werden, wie afrikanische Kräfte lokale und globale Strukturen von Ungleichheit, Ungerechtigkeit und schlechtes Regieren bekämpfen könnten? Und schlussendlich, wie können wir unseren afrikanischen Akademikerkollegen am besten dabei behilflich sein, dass sie zu Quellen von konstruktiver, interner Kritik werden?' (Autorenreferat)'Why do most Europeans see 'Africa' as feckless victim and 'the West' as a rescue service? How far are Africanists responsible for this misperception? How are you/ we to see to it that the EU and G8 act on the Commission for Africa's generally sound proposals? How far can we look to our predecessors for lessons in how to urge, not that Europe 'does something', but that Africans be allowed a better chance to help themselves? How far might our own analyses of Africans' societies, economies and polities be better adapted to exploring how far African agency might combat local and global structures of inequality, injustice, and misrule? How best, finally, can we help our African academic colleagues to become sources of constructive internal criticism?' (author's abstract)

Origin of Analcite in Igneous Rocks of the Terlingua District, Texas

Many of the igneous rocks of the Terlingua district in west Texas contain analcite as an important mineral. The analcite-bearing rocks generally are assemblages of andesine or labradorite, alkali feldspar, augite or aegirite-augite, olivine, iron ores, and analcite. Biotite is present in some types but absent in others. Important types are analcite syenogabbro, analcite trachybasalt porphyry, analcite trachycdolerite, and analcite syenite. Analcite was formed in these rocks through an extended period from late magmatic to definitely post magmatic stages. Reaction between the analcitic liquid and earlier formed minerals resulted in a series of reaction products including analcite aegirite-augite, serpentine, albite, and zeolites

Resolution of the Compact Radio Continuum Sources in Arp220

We present 2 cm and 3.6 cm wavelength very long baseline interferometry images of the compact radio continuum sources in the nearby ultra-luminous infrared galaxy Arp220. Based on their radio spectra and variability properties, we confirm these sources to be a mixture of supernovae (SNe) and supernova remnants (SNRs). Of the 17 detected sources we resolve 7 at both wavelengths. The SNe generally only have upper size limits. In contrast all the SNRs are resolved with diameters {\geq} 0.27 pc. This size limit is consistent with them having just entered their Sedov phase while embedded in an interstellar medium (ISM) of density 10^4 cm^{-3} . These objects lie on the diameter-luminosity correlation for SNRs (and so also on the diameter-surface brightness relation) and extend these correlations to very small sources. The data are consistent with the relation L {\propto} D^{-9/4}. Revised equipartition arguments adjusted to a magnetic field to relativistic particle energy density ratio of 1% combined with a reasonable synchrotron-emitting volume filling factor of 10% give estimated magnetic field strengths in the SNR shells of ~ 15-50 mG. The SNR shell magnetic fields are unlikely to come from compression of ambient ISM fields and must instead be internally generated. We set an upper limit of 7 mG for the ISM magnetic field. The estimated energy in relativistic particles, 2%-20% of the explosion kinetic energy, is consistent with estimates from models that fit the IR-radio correlation in compact starburst galaxies.Comment: 16 pages, 5 figure
