Bronze technology of the ancient megalithic communities in the Vidarbha region of India

Metallographic examination was carried out on forty-nine copper and bronze objects from five megalithic sites located in Vidarbha, India. The artifact assembly consists of horse ornaments, kitchenware, bangles, rings, small bells and the hilt of an iron dagger. Results show that the technology involved is characterized by the use of bronze alloys containing approximately 10% tin based on weight and the application of forging as a key method of fabrication. No deliberate addition of lead was observed. Arsenic was detected, but very rarely and only as an insignificant minor element. The consistent selection of such specific alloys indicates that the megalithic communities in this particular region had established a fully developed and standardized bronze tradition optimized for the production of forged items. Their advanced technological status was also noted in a special technique applied to two forged high-tin bronze bowls. Such a unique bronze tradition, dedicated to sheet metal technology, was most likely a practical choice made by these people to take advantage of the changing role of bronze. Specifically, with the introduction of iron, bronze seems to have become a more prestigious material that could serve as an indicator of the appearance of a more rigid socio-economic stratification within the megalithic communities of the Vidarbha region.     

Paleocene flora from Seymour Island,Antarctica: revision of Dusén’s (1908) angiosperm taxa

The Paleocene flora from Seymour Island, Antarctica, is one of the most diverse floras of this age in the Southern Hemisphere. First collected on the Swedish South Polar Expedition (1901–1903), it was described by Dusén in 1908 as having 87 leaf taxa. Forty-seven angiosperm taxa were described and/or illustrated. Many species are based on single specimens, and the flora has not been re-examined in its entirety since it was first described. This study is the first reassessment of the flora updating the original research using current methodologies, and permitting evaluation of the flora in the context of modern ideas on plant evolution and palaeogeography. This paper continues the revision of the material first studied by Dusén; a previous paper described the ferns and gymnosperms; here we describe the angiosperms. The revision is based on the original collections held at the Swedish Museum of Natural History, together with the first major new collections held at the British Antarctic Survey. Among the taxa recognized by Dusén, we recognize only three entire-margined and 11 tooth-margined angiosperms. This revision to 14 species notably lacks the two tropical elements originally described from the flora, Mollinedia seymourensis and Miconiiphyllum austral. Hence, its status as a ‘Mixed Flora’ comes into question and influences climatic interpretations based on Gondwanan floras. Anne-Marie Tosolini^?

The geography of community and political organisation in London today

Set in the context of growing concern about the lack of a coherent political response to the economic crisis, and in the aftermath of devastating urban violence in English cities, this paper highlights the pressing need for new forms of political organisation in countries like the UK. The paper focuses on the remarkable growth and prominence of community organising in the UK. The largest community alliance, called London Citizens, now commands significant support and influence in the capital and is attracting attention from politicians, journalists and commentators from across the UK. The rising profile of community organising flies in the face of much scholarship in the social sciences which has long declared the death of geographical community – and its socio-political significance – in the modern metropolis. The paper provides an overview of this literature and highlights the particular importance of population turnover, increased diversity and stretched social networks. In this context, the paper then explores how London Citizens has been able to use a particular geographical architecture to work with and against these challenges. The paper argues that London Citizens’ territorial but institutionally networked structure is particularly important to its growth and impact. This model of politics locates institutional islands of social solidarity and forges connections between them, creating a new community that is able to mitigate some of the effects of population turnover and stretched social networks in the city-at-large. The paper highlights the strengths and weaknesses of this geo-political architecture, drawing attention to the importance of institutional affiliation, identity-making, the reproduction of collective memory, and the issue of funding.     

Recent publications

A number of key events in the 1990s have helped shape the decade's cinema. The first of these is the conjuncture of the GATT negotiations (culminating in 1993) and the ascendancy of heritage cinema to mainstream dominance in French production at the expense of popular genres such as comedy and the polar. The second is the attempted return of the auteur through the influential 1994 television series ‘Tous les garçons et les filles de leur âge’. Finally, overlapping to some extent with the return of the auteur, is the arrival of a new generation of film‐makers whose political impact in the call for civil disobedience of February 1997 has undoubtedly affected the way in which the French view the films of this younger generation of directors.     

Egas Moniz and the Origins of Psychosurgery: A Review Commemorating the 50th Anniversary of Moniz's Nobel Prize

Modern psychosurgery began in 1936 with the work of the Portuguese neurologist, Egas Moniz, who attempted to treat the symptoms of mental illness by severing neural tracts in the frontal lobes. This procedure eventually became widespread and applied to thousands of institutionalized, psychotic patients in the United States and other countries. Despite serious side effects associated with psychosurgery, the apparent importance and validity of the treatment was recognized in 1949 when Moniz received the Nobel Prize for his innovation. Psychosurgery was largely replaced by anti-psychotic drugs in the mid-1950s, and the procedure and its practitioners rapidly fell into disrepute. This article reviews Moniz's career, the factors that led up to his first clinical trials of frontal lobe surgery, and the circumstances that allowed psychosurgery to flourish in the 1940s, eventually leading to Moniz's Nobel Prize.

The political economy of economic reform in North Korea

For over 10 years, North Korea has undergone a severe economic crisis, including food shortages, which has inflicted great suffering upon the North Korean people. Given such dire realities, it is beyond all doubt that the North Korean government should actively carry out comprehensive economic reforms as quickly as possible which aim to transform North Korea's present inefficient socialist planned economic system into a market economic system. Many argue that such reforms would give rise to successful economic growth in North Korea, which could enhance the legitimacy of the North Korean regime. Yet, the North Korean regime has consistently avoided implementing economic reforms, even though it has had a number of opportunities to do so. The July 1st reforms, which were introduced in 2002, have been half-hearted and inconsistently applied. This then raises an important question: Why has the North Korean government avoided adopting comprehensive economic reforms? In other words, what is the crucial barrier that has hindered North Korea's implementation of economic reforms? This article pinpoints North Korea's unique political system—i.e. its monolithic system of political control and policy making which exhibits the highest level of power concentration in one individual among all political systems—as the biggest barrier to economic reforms. No doubt North Korea desperately needs comprehensive economic reforms, in light of its economic crisis and food shortages. Nonetheless, the current North Korean regime has avoided adopting such reforms since they will undermine North Korea's monolithic system. In conclusion, North Korea's monolithic system has been the biggest obstacle to North Korea's economic reforms.     

Variability in single smelting episodes – a pilot study using iron slag from Uganda

Most archaeometallurgical studies of iron smelting are based on the analyses of slag fragments randomly selected from slag deposits, and assume that these samples are representative of the typical smelting conditions of the given context. However, little archaeometallurgical research has been published to explore the variability in slag composition within a single smelt, or between individual smelts at the same production site. The material used in this pilot study originates from two iron smelting sites identified in the Buganda Kingdom, Uganda, dated to the 18th and 19th centuries AD. The remains represent evidence of the industrial scale iron production that supported the growth and power of the kingdom. The slag survives in large clusters of complete blocks, in some cases weighing over 100 kg, each resulting from a single smelting episode in a pit furnace. A multi-sample analytical approach has allowed an insight into the compositional diversity within the slag from single smelting events, reflecting changing parameters in the smelting systems. The internal variation of the slag blocks is subsequently compared within and between sites, to address issues of standardisation and to differentiate two technological traditions that would appear very similar at the macroscopic level. On this basis, some sampling recommendations are made for future slag block studies.
