Pre-publicity for the final volume of Harold Macmillan’s memoirs, At the End of the Day, stressed that it would provide the British side of the Cuban missile crisis for the first time. The Churchillian model chosen, changes required by the Cabinet Office and Macmillan’s desire to rebuke those political opponents who claimed that the crisis demonstrated a lack of British influence in Washington, however ensured a focus on his personal relationship with President Kennedy. His larding the text with contemporary observations from his diaries also skewed Macmillan’s account and, in particular, underplayed the significance of British moves at the United Nations in New York to secure a credible United Nations inspection regime and a US guarantee of the inviolability of Cuba. Careful reconstruction of Macmillan’s real-time experience of the Cuban missile crisis demonstrates the limitations of his own account of this event

This chapter analyses the unfolding of the Cuban missile crisis in the context of the 17th General Assembly of the UN and shows that, contrary to earlier accounts, U Thant was responding to pressures from the non-aligned and the British in his attempts to handle the crisis.

This chapter analyses the successive ways in which Macmillan re-wrote his experiences of the Cuban missile crisis and in the process sought to re-configure the memory of the event in Britain.

This paper studies the evolution of the foreign trade specialization in manufacturing sectors of South Africa, Algeria, Nigeria and Egypt. These four countries, the so-called SANE, have recently been viewed as Africa’s best chance of producing an economic bloc whose role for Africa might be comparable to that of the BRIC economies of Brazil, Russia, India and China for the world economy. Using data on trade flows since mid-1970s, the results show that the SANE group has experienced few changes in its trade structure, which is still based on low-technology and slow-growth world demand sectors. The degree of persistence in the specialization model is higher in the case of Algeria and Nigeria, where the dependence on products based on natural resources is stronger.

Multi-parametric magnetic resonance imaging (mp-MRI) has become an increasingly important method for detecting and treating prostate cancer. Transrectal ultrasound (TRUS) is the most commonly used method for guiding prostate needle biopsy and remains the gold standard for diagnosis of prostate cancer. MRI-to-TRUS image reg- istration is an important technology for enabling computer-assisted targeting of the majority of prostate lesions that are visible in MRI but not independently distinguishable in TRUS images. The aim of this study was to estimate the needle placement accuracy of an image guidance system (SmartTargetÒ), developed by our research group, using a surgical training phantom.

Background The right occipital face area (rOFA) is known to be involved in face discrimination based on local featural information. Whether this region is involved in global, holistic stimulus processing is not known. Objective We used fMRI-guided transcranial magnetic stimulation (TMS) to investigate whether rOFA is causally implicated in stimulus detection based on holistic processing, by the use of Mooney stimuli. Methods Two studies were carried out: In Experiment 1, participants performed a detection task involving Mooney faces and Mooney objects; Mooney stimuli lack distinguishable local features and can be detected solely via holistic processing (i.e. at a global level) with top-down guidance from previously stored representations. Experiment 2 required participants to detect shapes which are recognized via bottom-up integration of local (collinear) Gabor elements and was performed to control for specificity of rightOFA's implication in holistic detection. Results In Experiment 1, TMS over rOFA and rLO impaired detection of all stimulus categories, with no category-specific effect. In Experiment 2, shape detection was impaired when TMS was applied over rLO but not over rOFA. Conclusions Our results demonstrate that rOFA is causally implicated in the type of top-down holistic detection required by Mooney stimuli and that such role is not face-selective. In contrast, rOFA does not appear to play a causal role in in detection of shapes based on bottom-up integration of local components, demonstrating that its involvement in processing non-face stimuli is specific for holistic processing.
