A co-operative training programme in the field of coastal and ocean management

AQUATIC CONSERVATION: MARINE AND FRESHWATER ECOSYSTEMS, Issue 4 2001
Stella Maris VallejoArticle first published online: 24 JUL 200
Abstract 1.,One of the major challenges that countries and institutions will face in the years to come is the massive training of personnel in the broad spectrum of disciplines and cross-sectoral perspectives needed to successfully implement integrated coastal zone management (ICZM) initiatives. 2.,This paper discusses the needs and challenges faced by institutions involved in training. 3.,In particular, the TRAIN,SEA,COAST Programme is discussed as an existing mechanism that provides an effective support system for training, with the focus on institution building at the national and regional levels, and increased cost-effectiveness.

Contribution to the stability analysis of the dewetted Bridgman growth under microgravity conditions

CRYSTAL RESEARCH AND TECHNOLOGY, Issue 6 2004
L. Bizet
Abstract Experimental observations show that the gap between the sample and the crucible, commonly obtained after solidification in microgravity, is remarkably stable. With the aim to understand the reason of this stability, the dewetting phenomenon is studied by Lyapunov's method. After a short review of the existing mechanisms leading to dewetting, the open smooth crucible configuration is chosen as the most representative. The analytical stability analysis, taking into account geometrical and thermal effects, performed under some boundary heat transfer approximations, shows that, in most cases, the dewetting process is intrinsically stable.

Strengthening Public Safety Nets from the Bottom Up

DEVELOPMENT POLICY REVIEW, Issue 5 2002
Jonathan Morduch
Helping to reduce vulnerability poses a new set of challenges for public policy. A starting point is understanding the ways in which communities and extended families try to cope with difficulties in the absence of public interventions. Coping mechanisms range from the informal exchange of transfers and loans to more structured institutions that enable an entire community to provide protection to its neediest members. This article describes ways of building public safety nets to complement and extend informal and private institutions. The most effective policies will combine transfer systems that are sensitive to existing mechanisms with new institutions for providing insurance and credit and for generating savings. [source]

Population trends of widespread woodland birds in Europe

IBIS, Issue 2007
RICHARD D. GREGORY
We explore population trends of widespread and common woodland birds using data from an extensive European network of ornithologists for the period 1980,2003. We show considerable differences exist in the European trends of species according to the broad habitat they occupy and the degree to which they specialize in habitat use. On average, common forest birds are in shallow decline at a European scale; common forest birds declined by 13%, and common forest specialists by 18%, from 1980 to 2003. In comparison, populations of common specialists of farmland have declined moderately, falling on average by 28% from 1980 to 2003. These patterns contrast with that shown by generalist species whose populations have been roughly stable over the same period, their overall index increasing by 3%. There was some evidence of regional variation in the population trends of these common forest species. The most obvious pattern was the greater stability of population trends in Eastern Europe compared with other regions considered. Among common forest birds, long-distance migrants and residents have on average declined most strongly, whereas short-distance migrants have been largely stable, or have increased. There was some evidence to suggest that ground- or low-nesting species have declined more strongly on average, as have forest birds with invertebrate diets. Formal analysis of the species trends confirmed the influence of habitat use, habitat specialization and nest-site; the effects of region and migration strategy were less clear-cut. There was also evidence to show that year-to-year variation in individual species trends at a European scale was influenced by cold winter weather in a small number of species. We recommend that the species trend information provided by the new pan-European scheme should be used alongside existing mechanisms to review the conservation status of European birds. The analysis also allows us to reappraise the role of common forest bird populations as a potential barometer of wider forest health. The new indicator appears to be a useful indicator of the state of widespread European forest birds and might prove to be a useful surrogate for trends in forest biodiversity and forest health, but more work is likely to be needed to understand the interaction between bird populations and their drivers in forest.

Towards regional monetary cooperation in East Asia: lessons from other parts of the world

INTERNATIONAL JOURNAL OF FINANCE & ECONOMICS, Issue 2 2005
Masahiro Kawai
Abstract This paper discusses regional monetary cooperation for East Asia, by drawing lessons from the European Payments Union, the CFA Franc Zone and the Arab Monetary Fund. Along with the well-known experience of the European Monetary System, these experiences suggest that effective monetary cooperation should include: (1) a surveillance mechanism; (2) a regional financing facility; (3) a common unit of account; and (4) exchange rate coordination. In East Asia, the existing mechanisms of regional surveillance must be strengthened, and the liquidity support mechanism under the Chiang Mai Initiative must evolve into a common pool of foreign exchange reserves. Over the longer term, the region may need to create its own common unit of account and to develop a framework for exchange rate coordination. Copyright © 2005 John Wiley & Sons, Ltd. [source]
