The Imām of Simonstown and his diary (1904-1928)

Includes abstract.Includes bibliographical references.This thesis is a study of Imām Muḥammad Ṣāliḥ Saban and his Diary within the context of the Simonstown Muslim community that he served from 1904 until 1928. The thesis presents the Diary, transcribed, edited, and digitised, for the sake of understanding the Imām’s contribution. It examines the Diary as a reflection of one man’s witness, open to study from a number of perspectives. Firstly, it presents a background to the early Muslim presence in Simonstown and its links with the Cape slave community. It then constructs a biography of the Imām, mainly on the evidence culled from the Diary, but supplemented by secondary sources. It then turns to the Diary as the Imām’s testimony. The Diary is compared with those of other diarists, who mostly represented a European dominant-class viewpoint of Simonstown. The thesis argues that the Imām’s Diary provides another perspective on the town and its inhabitants. Finally, the study presents the Diary as an insider testimony of the Imām, his role and authority, in the Cape

Editorial note

Now that we have successfully migrated to our new online platform, AJN has taken the additional step of adopting a “publish-as-you-go” strategy. Articles will be published once they have been accepted and there will no longer be the usual wait until the next issue is published. New articles will be added throughout the year and will therefore be available to be read and cited much sooner.The latest articles which we are now publishing include a short review by Halperin on the assessment of the renal response in patients with potassium disorders. Halperin first gave us the well-known transtubular K+ gradient (TTKG) but in recent years has been recommending the use of the urine K+/creatinine ratio instead. In this article he explains the reasons for this change.Kapembwa et al. present their data on technique survival in patients on peritoneal dialysis (PD) at Tygerberg Hospital in Cape Town. Successfully maintaining patients on PD is especially important when a PD-first policy is being followed, as is the case at their centre. The issue of the access of rural patients with chronic kidney disease to healthcare is the topic of the paper by Singh et al., who report on referral patterns at a tertiary centre in Durban, South Africa. The paper by Camara et al., from the Free State province, South Africa, describes the outcomes of patients with acute kidney injury who needed continuous renal replacement therapy. In their cohort, patients with HIV infection were substantially younger and had a much worse outcome.Finally, the report by Makhoba et al. describes a case of osseous metaplasia in a renal allograft.M Razeen DavidsAssociate Edito

Uniform electron gases: III. Low-density gases on three-dimensional spheres

By combining variational Monte Carlo (VMC) and complete-basis-set limit Hartree-Fock (HF) calculations, we have obtained near-exact correlation energies for low-density same-spin electrons on a three-dimensional sphere (3-sphere), i.e.~the surface of a four-dimensional ball. In the VMC calculations, we compare the efficacies of two types of one-electron basis functions for these strongly correlated systems, and analyze the energy convergence with respect to the quality of the Jastrow factor. The HF calculations employ spherical Gaussian functions (SGFs) which are the curved-space analogs of cartesian Gaussian functions. At low densities, the electrons become relatively localized into Wigner crystals, and the natural SGF centers are found by solving the Thomson problem (i.e. the minimum-energy arrangement of $n$ point charges) on the 3-sphere for various values of $n$. We have found 11 special values of $n$ whose Thomson sites are equivalent. Three of these are the vertices of four-dimensional Platonic solids --- the hyper-tetrahedron ($n=5$), the hyper-octahedron ($n=8$) and the 24-cell ($n=24$) --- and a fourth is a highly symmetric structure ($n=13$) which has not previously been reported. By calculating the harmonic frequencies of the electrons around their equilibrium positions, we also find the first-order vibrational corrections to the Thomson energy.Comment: 6 pages, 2 figures, accepted for publication in the Journal of Chemical Physic

Proximity, knowledge base and the innovation process : the case of Unilever's Becel diet margarine

The proximity concept refers to types of inter-organizational relationships that are expected to facilitate interactive learning and collaborative innovation. Different forms of proximity include geographical, cognitive, social, institutional and organizational proximity. Following an extensive case study of a new diet margarine developed by Unilever, we extend the proximity framework by theorizing how the relative importance of each proximity dimension depends on the type of knowledge being produced, where we distinguish between analytical, synthetic and symbolic knowledge. We argue that our theoretical framework in principle applies to product innovations in all science-based industries
