Satellite tracking of the World's largest bony fish, the ocean sunfish (Mola mola L.) in the North East Atlantic

Satellite-linked archival transmitters were used to record the movements of three ocean sunfish (Mola mola) in the North East Atlantic. Patterns of depth use and temperature experienced by individual fish were integrated into 4-hour intervals throughout the tracking period and relayed via the Argos system. Data were recorded for 42, 90 and 54 days respectively from the three fish. The first two were tagged off southern Portugal at the end of February 2007 and travelled principally northward, while the third fish was tagged off west Ireland in August 2007 and travelled southward. These patterns are consistent with seasonal migration of ocean sunfish to high latitudes and their Subsequent return south. Maximum depths recorded by the three fish were 432 m, 472 m and 320 m respectively. All three individuals showed a diel pattern in depth use, occurring deeper during the day and shallower at night, a pattern consistent with sunfish tracking normally vertically migrating prey. Sunfish sometimes remained continuously at deeper (>200 m) depths during the day, but at other times they showed extensive movement through the water column typically travelling between their maximum depth and the surface within each 4-h period. The overall pattern to emerge was that ocean sunfish travel extensively in both horizontal and vertical dimensions, presumably in search of their patchily-distributed jellyfish prey.

Infrared emission from tunneling electrons: The end of the rainbow in scanning tunneling microscopy

Electromagnetic radiation originating with localized surface plasmons in the metal-tip/metal-sample nanocavity of a scanning tunneling microscope is demonstrated to extend to a wavelength lambda of at least 1.7 mu m. Progressive spectral extension beyond lambda similar to 1.0 mu m occurs for increasing tip radius above similar to 15 nm, reaching lambda similar to 1.7 mu m for tip radius similar to 100 nm; these observations are corroborated by use of a simple physical model that relates the discrete plasmon mode frequencies to the tip radius. This spectral extension opens up a new regime for scanning tunneling microscope-based optical spectroscopy.

China and the changing landscape of the world economy

The rapid development of emerging markets is changing the landscape of the world economy and may have profound implications for international relations. China is often regarded as the most influential emerging market economy because, during the last three decades, it has become increasingly integrated into the world economic system and its success and failure now affect the well-being of other nations in the world. As the financial crisis in the US and EU intensifies, the economic prosperity of the world depends to a large extent on the sustained development of the Chinese economy and other emerging markets, and vice versa.

The End of the Urban-Rural Divide?

The urban-rural divide in China was an entrenched feature of Chinese society in the Maoist era. This divide generated and continues to generate inequality as between the rural population and the urban population. In post-Deng China, legal and administrative distinctions between urban and rural have become blurred, especially with the development of rural-urban migration. Nevertheless, the urban-rural divide still exists, and the income of farmers is below that of urban residents. In this paper, it is argued that the emergence of the phenomenon of “quasi-commons” in rural China, crossing the “borders” of the urbanrural divide, may increase farmers’ income in the future and bridge this divide. The paper focuses on different forms of “quasi-commons” (the sharing and use of communal land) emerging in rural areas, including the farmland shareholding cooperatives and transforming rural land management rights into shares in joint ventures. There are divergent views held by Chinese academics and policy makers about “quasi-commons” in rural China, as well as the direction of change in the rural land system. However, most of the proposals for reform have been polarized between nationalization and privatization of rural land. Looking beyond this “boundary thinking” and drawing on the discourses of “the commons” (for example, the writings of Hardin, Heller and Ostrom), this paper analyses the theoretical models of both the nationalization and privatization schemes and their shortcomings. The present essay also analyses the prospect for, and the barriers to the emerging commons in rural China.

An anthropometric history of the World, 1810-1980: did migration and globalization influence country trends?

We find that regional height levels around the world were fairly uniform throughout most of the 19th century, with two exceptions: above-average levels in Anglo-Saxon settlement regions and below-average levels in Southeast Asia. After 1880, substantial diver- gences began to differentiate other regions -- making the world population taller, but more unequal. During the late 19th century and 20th century, heights between world regions devi- ated significantly, when incomes also became very unequal. Interestingly, during the “breaking point period” between the two regimes, heights declined significantly in the cattle-rich New World countries, whereas they started to increase in Old Europe. We discuss in this study whether immigration was a core factor to influence the height decline in the “Anthropometric Decline of the Cowboy and Gaucho Empires”.

'The End of the Irish Poor Law?: Welfare and Healthcare Reform in Revolutionary and Independent Ireland'

This book explores welfare provision in Ireland from the revolutionary period to the 1940s, This work is a significant addition to the growing historiography of twentieth-century Ireland which moves beyond political history. It demonstrates that concepts of respectability, deservingness, and social class where central dynamics in Irish society and welfare practices. This book provides the first major study of local welfare practices, policies, and attitudes towards poverty and the poor in this era.

This book’s exploration of the poor law during revolutionary and independent Ireland provides fresh and original insights into this critical juncture in Irish history. It charts the transformation of the former workhouse system into a network of local authority welfare and healthcare institutions including county homes, county and hospital hospitals, and mother and baby homes. This book provides historical context to current day debates and controversies relating to the institutionalisation of unwed mothers and child welfare policies.

This book undertakes two cases studies on county Kerry and Cork city; also, Irish experiences are placed against the backdrop of wider transnational trends.

This work has multiple audiences and will appeal to those interested in Irish social, culture, economic and political history. This book will also appeal to historians of welfare, the poor law, and the social history of medicine. It also informs modern-day social affairs.
