- Description: In 2007, a former South African Defence Force (SADF) paratrooper, Marius van Niekerk, embarked on a journey to confront his shameful memories relating to his role in the Angolan Civil War. From Sweden (where he had gone into exile), Van Niekerk returned to Angola, where he had been deployed during the mid-1980s, and recruited three other veterans of the war to join his party: Patrick Johannes, who had been coerced to fight for the Popular Armed Forces for the Liberation of Angola (FAPLA); Samuel Machado Amaru, who was forcefully enlisted by the National Union for the Total Independence of Angola (UNITA); and Mario Mahonga, who had fought for the Portuguese colonial army before he was recruited by the SADF to fight against the Popular Movement for the Liberation of Angola (MPLA) regime. Van Niekerk had been conscripted at the age of seventeen, and the others had been coerced into their respective militias at more tender ages. It is not clear how the three Angolans were induced to participate in the project, whose objectives they evidently did not share.

- Description: In Liberation movements in power, Roger Southall provides a rich and refined account of political transformation in three ex-settler colonies in southern Africa, namely, South Africa, Namibia and Zimbabwe. In particular, he focuses on their former hegemonic national liberation movements, namely, the African National Congress (ANC) in South Africa, the South West African People’s Organisation (SWAPO) in Namibia and the Zimbabwe African National Union (ZANU) – now ZANU-Patriotic Front (ZANU-PF) – in Zimbabwe, their metamorphism into political parties and party machines, and their ‘capture’ of state power as the dominant political party subsequent to the end of white settler colonialism and the emergence of non-racial democracy. The general conclusion is that democratic ideals and procedures have become subordinated to the dictates of authoritarian restructuring.

- Description: A prominent vertical dolerite dyke, up to 30 m wide and which can be traced for over 100 km, is compositionally homogeneous along much of its length and shows no evidence of flow differentiation. Associated parallel dykes are compositionally distinct and are unrelated by closed-system processes. The main dyke has geochemical characteristics of the Maloti or Senqu Units in the upper part of the main Lesotho basalt sequence, whereas the parallel dykes are geochemically similar to the lower Mafika Lisiu Unit. On the basis of size and composition the main dyke may well represent a fissure which once fed effusions of Karoo basalt.

- Description: This ambitious book begins with the statement ‘By and large, the states of sub-Saharan Africa are failures’ (p. 1) and then sets out to explain state failure in Africa and to provide some ‘rational policy fantasies’ in response to this failure. The book builds on the work of scholars like Robert Jackson, William Reno and Jeffrey Herbst, with the particular focus of Englebert's book being on the domestic implications of the unconditional recognition of the sovereignty of African states. African states are internationally recognised despite lacking the features and not being able to perform the functions typically associated with statehood. Englebert's interest is to examine some of the domestic effects of this unconditional international recognition.

- Description: In this latest book, Graeme Turner, who we have come to know as a thoughtful, perceptive and questioning cultural studies theorist, investigates what the crucial underlying shift is in the relation between the media and the people. This shift is evidenced by the increasing visibility of ordinary people (and their experiences and opinions) in what we consume. At the outset he sums up what he sees as a structural move from media as ‘mediator or perhaps a broadcaster of cultural identities’ to ‘translator or even an author of identities’ (p. 3).

There are several ways of understanding the creative economy, often divided into the cultural and creative industries. Cultural industries are those whose major outputs have some symbolic value, such as fine arts, film and craft, jewelry design, publishing and fashion. Creative industries are defined more broadly as those that have knowledge as their major input. In addition to cultural goods and services, these include things like software design and internet services. UNESCO (2009) provides guidelines for defining the cultural and creative industries and the ways in which they can be measured, but there is currently no international consensus. Nor is there likely to be, since different countries will have very different levels of involvement and focus that may shape what information is useful, for example, for shaping policy.

The determinants and extent of non-compliance are commonly incorrectly perceived by doctors. During routine therapeutic drug monitoring of epileptic and asthmatic outpatients at a local day hospital, non-compliance was identified as a significant problem. A compliance study was conducted on 80 epileptic and asthmatic patients to determine the nature and extent of this problem. Non-compliance was measured using four different methods, which were then compared using chi 2 tests.

- Description: There have been almost two decades of democracy in South Africa, yet rising anger and violent discontent lay bare continuing inequity. It is timely to ask the question: can South Africans really be frank about how meaningful the transformation from oppressive political and economic structures has been? Does the inclination towards neo-liberalism and capitalism in South Africa’s post-Apartheid democracy allow real change? Where economic inequality and spatial divisions still persist and, indeed, are actively reproduced by current market forces, can South Africans really create inclusive and integrative spaces? The Art of Change: Perspectives on Transformation in South Africa confronts some of these issues, reopening debates and encouraging reflection on cultural dynamics in South Africa during the past two decades.

- Description: publisher version , There is no defined route to becoming an academic developer. The research on pathways into the field (e.g. Kensington-Miller, Brailsford, and Gossman, 2012; McDonald, 2010; McDonald and Stockley, 2008) shows that in most cases ‘serendipity and chance played a role’ (McDonald, 2010, p. 40). Moreover, induction into academic development (AD) is often ad hoc, haphazard, and informal. Due to the changing higher education (HE) context, the field has grown exponentially and in many countries now plays a central role in institutions. This has generated increased demand for knowledgeable and competent developers that are able to contribute towards solving some vexing problems in contemporary HE. Current recruitment and induction processes of new developers do not necessarily meet this demand. In light of the above, we pose the question: given the changing context of HE and the field of AD, is it not time for us to induct newcomers into the field more systematically? As Kensington-Miller et al. (2012) suggest, we should not leave the induction of the next generation of developers to chance. We suggest that one way of ensuring appropriate induction is through a formal course for developers. Difficulties for newcomers to the field are illustrated by Kensington-Miller et al. (2012) when they report seeking ‘top tips’ at a HERDSA conference. We do not dismiss informal learning at conferences or the role of mentoring, coaching, apprenticeship, and so on, in inducting developers, nor do we minimise the benefits of relatively structured processes such as fellowship programmes, workshops, and postgraduate qualifications in related fields. However, these ways of induction may not offer novices the structured and systematic developmental opportunities needed to become developers able to fulfil varied, complex, and sometimes contradictory roles.

- Description: Quartz is a common natural mineral with properties that make it amenable for application in radiation dosimetry using luminescence methods [1]. The luminescence properties of quartz including its sensitivity and luminescence lifetimes undergo notable changes when the quartz is annealed, and in particular, near its phase inversion temperatures of 573 and 867 oC [2, 3]. The physical processes leading up to the emission of luminescence in quartz may be investigated using time-resolved optical stimulation. The aim of this method is to separate in time the stimulation and emission of luminescence to enable measurement of time-resolved luminescence spectra which may be resolved into associated lifetimes, defined in this sense as the delay between stimulation and emission of luminescence [4, 5]. A number of such studies show that annealing defines the detailed distribution of lifetimes with measurement temperature as well as the irradiation-dependent characteristics of the lifetimes [3, 6]. In particular, it was noted [3] that spectra measured at certain temperatures could be accurately resolved into more than one component, a scenario that pointed to the possibility of involvement of multiple luminescence centers in the emission of luminescence from quartz. The aim of this work is to build on the findings described, specifically to study the influence of measurement temperature and irradiation on the principal and subsidiary luminescence lifetimes in natural quartz.

- Description: Quartz is a common natural mineral with properties that make it amenable for application in radiation dosimetry using luminescence methods [1]. The luminescence properties of quartz including its sensitivity and luminescence lifetimes undergo notable changes when the quartz is annealed, and in particular, near its phase inversion temperatures of 573 and 867 oC [2, 3]. The physical processes leading up to the emission of luminescence in quartz may be investigated using time-resolved optical stimulation. The aim of this method is to separate in time the stimulation and emission of luminescence to enable measurement of time-resolved luminescence spectra which may be resolved into associated lifetimes, defined in this sense as the delay between stimulation and emission of luminescence [4, 5].

A critical psychology of the postcolonial: the mind of apartheid. A book review
- Authors: Matthews, Sally
- Date: 2012

- Description: This book provides a careful and detailed defence of the idea that the (post)colonial condition, and particularly the role that race has played in the (post)colony, cannot properly be understood without the theorisation of the ‘psychopolitical’. By the ‘psychopolitical’, Hook refers to ‘a reciprocal form of critique in which we not only place the psychological within the register of the political, but, perhaps more challengingly, in which the political is also – although strategically – approached through the register of the psychological’ (p. 40). In order to do this, Hook engages with and develops upon the insights of some key postcolonial thinkers, most notably Frantz Fanon and Homi Bhabha. Hook argues convincingly that concepts and approaches from psychoanalysis are helpful in properly understanding the postcolonial condition and, particularly, in getting to grips with the malleability and persistence of racism.

- Description: Molecular dynamics (MD) determines the physical motions of atoms of a biological macromolecule in a cell-like environment and is an important method in structural bioinformatics. Traditionally, measurements such as root mean square deviation, root mean square fluctuation, radius of gyration, and various energy measures have been used to analyze MD simulations. Here, we present MD-TASK, a novel software suite that employs graph theory techniques, perturbation response scanning, and dynamic cross-correlation to provide unique ways for analyzing MD trajectories.

- Description: Radioluminescence spectra of Al2O3:C,Mg monitored at temperatures up to 400 °C is reported. Measurements were made on samples either as received or on ones annealed at 1200 °C. Radioluminescence is observed at 410 nm for the unannealed sample but principally at 330 and 410 nm in the annealed sample with the emission at 330 nm dominant. Both bands are subject to thermal quenching but the change for the F+ band is atypical. Temperature induced effects on these and other bands are discussed, as are complementary measurements of thermoluminescence spectra.
