Centurions and Chieftains : tank sales and British policy towards Israel in the aftermath of the Six Day War

Britain's attempt to distance itself from Israel as London sought to conciliate the Arab world in the aftermath of the Six-Day War has entered the historiography of Anglo-Israeli relations. A neglected aspect of the development of British policy towards Israel has been the intense debates among British decision-makers regarding the supply of tanks to Israel following the 1967 conflict. British reluctance to export the powerful Chieftain tank to Israel stemmed not only from an unwillingness to fuel an arms race in the Middle East, but also from a determination to protect ongoing and extensive British economic interests in the Arab world, especially oil supplies. In keeping with efforts to dissociate itself from Israel, Britain also sought to downplay, and even conceal from the Arab world, ongoing sales of the less sophisticated Centurion tank to Israel. In many ways, British policy towards Israel culminated in the decision during the 1973 Yom Kippur War to maintain an arms embargo to the region which, while not extending to all Arab countries, hit Israel especially hard as it desperately sought ammunition and spares for its Centurion tanks

Britain’s decision to withdraw from the Persian Gulf: a pattern not a puzzle

The reasons for the British decision to withdraw from the Gulf are highly contentious. While some scholars have focused on short-term considerations, especially the devaluation of sterling towards the end of 1967, in the British determination to quit the Gulf, others have concentrated on longer-term trends in British policy-making for the region. This article sides with the latter. Britain's Gulf role came under increasing scrutiny following the 1956 Suez crisis as part of an ongoing debate about the costs and benefits of Britain's Gulf presence. In this sense, British withdrawal fitted into a wider pattern of British decolonisation. By the 1960s, the Treasury, in particular, strongly questioned the necessity and cost-effectiveness of the maintenance of empire in the Gulf to safeguard British economic interests there. Recent interpretations which seek to disaggregate the British decision to leave Southeast Asia from the decision to depart from the Gulf are also questionable. By mid-1967, it had already been determined that Britain would leave both regions by the mid-1970s, the only difference being that this decision was formally announced with respect to Southeast Asia, but not with regard to the Gulf. The devaluation of sterling in November 1967, therefore, merely hastened and facilitated decisions which had already been taken. Despite the end of formal empire in the Gulf, Britain did seek, not always successfully, to preserve its interests into the 1970s and beyond

Subdegree growth rates of infinite primitive permutation groups

A transitive group $G$ of permutations of a set $\Omega$ is primitive if the only $G$-invariant equivalence relations on $\Omega$ are the trivial and universal relations. If $\alpha \in \Omega$, then the orbits of the stabiliser $G_\alpha$ on $\Omega$ are called the $\alpha$-suborbits of $G$; when $G$ acts transitively the cardinalities of these $\alpha$-suborbits are the subdegrees of $G$. If $G$ acts primitively on an infinite set $\Omega$, and all the suborbits of $G$ are finite, Adeleke and Neumann asked if, after enumerating the subdegrees of $G$ as a non-decreasing sequence $1 = m_0 \leq m_1 \leq ...$, the subdegree growth rates of infinite primitive groups that act distance-transitively on locally finite distance-transitive graphs are extremal, and conjecture there might exist a number $c$ which perhaps depends upon $G$, perhaps only on $m$, such that $m_r \leq c(m-2)^{r-1}$. In this paper it is shown that such an enumeration is not desirable, as there exist infinite primitive permutation groups possessing no infinite subdegree, in which two distinct subdegrees are each equal to the cardinality of infinitely many suborbits. The examples used to show this provide several novel methods for constructing infinite primitive graphs. A revised enumeration method is then proposed, and it is shown that, under this, Adeleke and Neumann's question may be answered, at least for groups exhibiting suitable rates of growth.Comment: 41 page

Priests and politicians: Archbishop Michael Gonzi, Dom Mintoff, and the end of empire in Malta

The political contest in Malta at the end of empire involved not merely the British colonial authorities and emerging nationalists, but also the powerful Catholic Church. Under Archbishop Gonzi’s leadership, the Church took an overtly political stance over the leading issues of the day including integration with the United Kingdom, the declaration of an emergency in 1958, and Malta’s progress towards independence. Invariably, Gonzi and the Church found themselves at loggerheads with the Dom Mintoff and his Malta Labour Party. Despite his uncompromising image, Gonzi in fact demonstrated a flexible turn of mind, not least on the central issue of Maltese independence. Rather than seeking to stand in the way of Malta’s move towards constitutional separation from Britain, the Archbishop set about co-operating with the Nationalist Party of Giorgio Borg Olivier in the interests of securing the position of the Church within an independent Malta. For their part, the British came to accept by the early 1960s the desirability of Maltese self-determination and did not try to use the Church to impede progress towards independence. In the short-term, Gonzi succeeded in protecting the Church during the period of decolonization, but in the longer-term the papacy’s softening of its line on socialism, coupled with the return to power of Mintoff in 1971, saw a sharp decline in the fortunes of the Church and Archbishop Gonzi

Languages adapt to their contextual niche

abstractIt is well established that context plays a fundamental role in how we learn and use language. Here we explore how context links short-term language use with the long-term emergence of different types of language system. Using an iterated learning model of cultural transmission, the current study experimentally investigates the role of the communicative situation in which an utterance is produced (situational context) and how it influences the emergence of three types of linguistic systems: underspecified languages (where only some dimensions of meaning are encoded linguistically), holistic systems (lacking systematic structure), and systematic languages (consisting of compound signals encoding both category-level and individuating dimensions of meaning). To do this, we set up a discrimination task in a communication game and manipulated whether the feature dimension shape was relevant or not in discriminating between two referents. The experimental languages gradually evolved to encode information relevant to the task of achieving communicative success, given the situational context in which they are learned and used, resulting in the emergence of different linguistic systems. These results suggest language systems adapt to their contextual niche over iterated learning.</jats:p

The Anglo-American 'special relationship' and the Middle East, 1945-1973

It is widely recognised that the Anglo-American ‘special relationship’ fluctuated following the Second World War. A “Persistent rivalry” was especially evident in policy towards the Middle East and its oil. Immediately after the war, the American attitude to Palestine seemed to complicate British policy. Events in Iran also reflected the clash between the British imperative to protect its national and imperial interests in the region on the one hand, and the American preoccupation with the Cold War and containment on the other. The subsequent differences over Egypt/ Nasser are a matter of public record as are the problems which arose over the British withdrawal from “East of Suez”. Perhaps the very closeness of the relationship between the UK and the US served to heighten expectations

Spectral Response of the Pulsationally-Induced Shocks in the Atmosphere of BW Vulpeculae

The star BW Vul excites an extremely strong radial pulsation that grows in its envelope and is responsible for visible shock features in the continuum flux and spectral line profiles emerging in the atmosphere At two phases separated by 0.8 cycles. Material propelled upwards in the atmosphere from the shock returns to the lower photosphere where it creates a second shock just before the start of the next cycle. We have obtained three nights of echelle data for this star over about 5 pulsation cycles (P = 0.201 days) in order to evaluate the effects of on a number of important lines in the spectrum, including the HeI 5875A and 6678A lines. These data were supplemented by archival high-dispersion IUE (UV) data from 1994. A comparison of profiles of the two HeI lines during the peak of the infall activity suggests that differences in the development of the blue wing at this time are due to heating and short-lived formations of an optically thin layer above the atmospheric region compressed by the infall. This discovery and the well-known decreases in equivalent widths of the CII 6578-83A doublet at the two shock phases, suggests that shock flattens the temperature gradient and produces heating in heating the upper atmosphere. Except for absorptions in the blue wings of the UV resonance lines, we find no evidence for sequential shock delays arriving at various regions of line formation of the photosphere (a "Van Hoof effect"). Phase lags cited by some former observers may be false indicators arising from varying degrees of desaturation of multiple lines, such as for the red HeI lines. In addition, an apparent lag in the equivalent width curve of lines arising from less excited atomic levels could instead be caused by post-shock cooling, followed by a rebound shock.Comment: 12 pages in Latex/MNRAS format, 9 eps-format figure
