Half-precessional dynamics of monsoon rainfall near the East African Equator

External climate forcings-such as long-term changes in solar insolation-generate different climate responses in tropical and high latitude regions(1). Documenting the spatial and temporal variability of past climates is therefore critical for understanding how such forcings are translated into regional climate variability. In contrast to the data-richmiddle and high latitudes, high-quality climate-proxy records from equatorial regions are relatively few(2-4), especially from regions experiencing the bimodal seasonal rainfall distribution associated with twice-annual passage of the Intertropical Convergence Zone. Here we present a continuous and well-resolved climate-proxy record of hydrological variability during the past 25,000 years from equatorial East Africa. Our results, based on complementary evidence from seismic-reflection stratigraphy and organic biomarker molecules in the sediment record of Lake Challa near Mount Kilimanjaro, reveal that monsoon rainfall in this region varied at half-precessional (similar to 11,500-year) intervals in phase with orbitally controlled insolation forcing. The southeasterly and northeasterly monsoons that advect moisture from the western Indian Ocean were strengthened in alternation when the inter-hemispheric insolation gradient was at a maximum; dry conditions prevailed when neither monsoon was intensified and modest local March or September insolation weakened the rain season that followed. On sub-millennial timescales, the temporal pattern of hydrological change on the East African Equator bears clear high-northern-latitude signatures, but on the orbital timescale it mainly responded to low-latitude insolation forcing. Predominance of low-latitude climate processes in this monsoon region can be attributed to the low-latitude position of its continental regions of surface air flow convergence, and its relative isolation from the Atlantic Ocean, where prominent meridional overturning circulation more tightly couples low-latitude climate regimes to high-latitude boundary conditions.

Gender and Welfare States in East Asia: Confucianism or Equality?

Is a Confucian cultural climate hostile to gender equality in families and public decision-making? What is the impact of gender equality legislation in East Asia? Approaches to these welfare regimes have ignored gender, while gendered accounts of welfare have neglected East Asia. Comparisons with Western welfare states show strong economies with life expectancy in Japan and South Korea above those of Western social democracies but in contrast there are extremely large gender gaps in employment, earning, unpaid work and parliamentary representation and conjoined with this low fertility rates and and minimal public social spending on childcare and early education.

In this volume, contributors address questions about gender equality in a Confucian context across a wide and varied social policy landscape, from Korea and Taiwan, where Confucian culture is deeply embedded, through China, with its transformations from Confucianism to communism and back, to the mixed cultural environments of Hong Kong and Japan. Overall, the collections asks: Has East Asia's rapid economic transformation been accompanied by social and cultural transformation?

'In the Service of the Honourable East India Company': Politics and Identity in Dean Mahomet's Travels (1794)

The successful career of Dean Mahomet (1759-1851) as a migrant from India to Ireland (and later, England) has led to scholarly and popular interest in his work. His Travels through several parts of India in the Service of the Honourable East India Company (1794) published by subscription in Cork is reputedly the first English book by an Indian, and has been seen to counterbalance the many accounts of India by western travellers, and to assert, in autobiographical form, his identity as an Indian in 1790s Ireland. My paper analyses this text in relation to moral and economic criticisms of the East India Company in the eighteenth century, and in particular to legislation of 1793 which defined the role of the Company in Ireland’s trade with the east. These aspects of colonial politics involving Ireland and India as subject nations of Britain are shown to shape Mahomet’s discursive strategies and the complex identity produced in his text.

Phocine distemper virus in seals, East Coast, United States, 2006

In 2006 and 2007, elevated numbers of deaths among seals, constituting an unusual mortality event, occurred off the coasts of Maine and Massachusetts, United States. We isolated a virus from seal tissue and confirmed it as phocine distemper virus (PDV). We compared the viral hemagglutinin, phosphoprotein, and fusion (F) and matrix (M) protein gene sequences with those of viruses from the 1988 and 2002 PDV epizootics. The virus showed highest similarity with a PDV 1988 Netherlands virus, which raises the possibility that the 2006 isolate from the United States might have emerged independently from 2002 PDVs and that multiple lineages of PDV might be circulating among enzootically infected North American seals. Evidence from comparison of sequences derived from different tissues suggested that mutations in the F and M genes occur in brain tissue that are not present in lung, liver, or blood, which suggests virus persistence in the central nervous system.

Escalators, Elevators and Travelators: The Occupational Mobility of Migrants to South-East England

In a meritocratic society it is assumed that the chance of achieving occupational mobility (OM) is not strongly influenced by one's starting position in terms of class or ethnicity. This paper seeks to explain the drivers of the high levels of OM achieved by one ethnically defined group: the Scots. Educational attainment is shown to be particularly important. A second level of interest is the changing role of internal migrants to a global city in the face of increased international skilled immigration. We investigate whether there is any evidence that the OM of internal migrants is being hindered as a result. The evidence points instead to immobile local labour being more disadvantaged occupationally than mobile labour from peripheral regions of the state.
