The allocation of development aid assistance : do new donors have old motives?

The aid allocation literature explores the motives behind development aid&nbsp; assistance. This literature is enormous, yet surprisingly, the extant empirical&nbsp; studies have in the main only focused on the motives of established donors. Consequently, relatively little is known of the motives of new donors. This paper explores the aid allocation motives of three relatively new DAC donors: Greece, Luxembourg, and Portugal. Both OLS and Tobit two-way effects estimators are used to model their aid allocation process. The results indicate that humanitarian concerns are not an important factor for these three donors. Greece contributes aid predominately to its neighbors and to transitional East European nations. Portugal is motivated by commercial interests and former colony status. The bandwagon effect exists in reverse for Portugal. Commercial interests operate also for Luxembourg. Additionally, Luxembourg appears to donate to smaller more developed countries and is less inclined to donate to East European nations.<br />

Change in the diet of sooty owls (Tyto tenebricosa) since European settlement: from terrestrial to arboreal prey and increased overlap with powerful owls

The current diet of the sooty owl (<i>Tyto tenebricosa</i>) was determined by analysing freshly regurgitated pellets collected beneath their roosting sites in East Gippsland, Victoria. Comparisons were then made with: (i) prehistoric and historic diet from bone deposits found in cave roosts, and (ii) diet of a sympatric owl species, the powerful owl (<i>Ninox strenua</i>). Sooty owls consumed a large array of terrestrial mammal species before European settlement, but only three terrestrial species were detected in their current diet, a reduction of at least eight species since European settlement. To compensate, sooty owls have increased their consumption of arboreal prey from 55% to 81% of their diet. Arboreal species are also a major component of the powerful owl diet and this prey shift by sooty owls has increased dietary overlap between these two species. Predation by foxes (<i>Vulpes </i><i>vulpes</i>) and other feral species is likely to have reduced the amount of terrestrial prey available to sooty owls since European settlement. Investigation of changes in the diet of sooty owls may offer a unique monitoring system for evaluating the ability of fox-control strategies to influence increases in numbers of critical-weight-range mammals.<br />

Isogramma Meek and Worthen, 1870 (Dictyonellida, Brachiopoda) from the upper Palaeozoic of East Asia: implications for biogeography and evolutionary trends

<i>Isogramma manchoukuoensis</i> from the Upper Carboniferous of northeast China is redefined based on re-examination of the type specimens. <i>Isogramma </i>specimens from the Middle Permian of northeastern Japan are reassigned to I. aff. <i>paotechowensis</i>. A new family, Schizopleuroniidae, is proposed to include <i>Schizopleuronia</i>, but excludes <i>Megapleuronia</i>, which belongs to the Megapleuroniidae Liao, 1983. The family Isogrammidae is considered to be a transitional group in the eichwaldid-isogrammid-schizopleuronid evolutionary lineage within the Dictyonellida. A review of the global distribution of <i>Isogramma </i>species reveals that the genus has a total of 56 species ranging from the Mississippian (Early Carboniferous) to the Lopingian (Late Permian). <i>Isogramma </i>diversified rapidly after its origination in the middle Vis&eacute;an and its species diversity remained high throughout the Mississippian. The genus possibly suffered a severe mid-Carboniferous boundary mass extinction, with no Early Carboniferous species surviving this event. Bashkirian <i>Isogramma </i>species show low diversity, followed by a global recovery in the Moscovian. During the latest Carboniferous <i>Isogramma </i>became highly diversified again. At the Carboniferous&ndash;Permian (C/P) transition <i>Isogramma </i>underwent another dramatic diversity drop, followed by several stepwise declines in diversity during the Early&ndash;Middle Permian. The Wuchiapingian <i>I. sinosa</i> is the last <i>Isogramma </i>species.<br /><br />Ukraine was the possible centre of origin for <i>Isogramma</i>. From Ukraine <i>Isogramma </i>spread over the Moscow Basin of Russia, Central Europe (Germany, Austria), South Europe (Spain) and West Europe (England, Ireland and Scotland), and migrated to the North American midcontinent and South China during the late Vis&eacute;an (Early Carboniferous). In Europe, <i>Isogramma </i>migrated to Spain and eastern Europe (Serbia) in the Moscovian, from there it then dispersed into Central Asia (Uzbekistan and Kazakhstan) in the Kasimovian-Gzhelian. In the Palaeo-Tethys <i>Isogramma </i>migrated from South China to northeast and northwest China in the Moscovian, spread over the North China Block during the C/P transition, moved to Russian Siberia, Japan and the Qiangtang terrane of the Palaeo-Tethys during the Early&ndash;Late Permian. In North America <i>Isogramma </i>spread over the midcontinent during the Late Carboniferous and Early&ndash;Middle Permian and migrated to South America (Bolivia) in latest Carboniferous. Biogeographically, <i>Isogramma </i>was confined principally to the palaeo-tropical and warm to temperate zones throughout the Late Palaeozoic, with the possible exception of the Artinskian, as a questionable species of the genus also occurs in the Transbaikal region of southeast Russia.<br />

Crusader churches in the Latin East : expressions of medieval theology

The Latin invaders of the Eastern Mediterranean in the 12th-14th Centuries were on a mission to retrieve and protect the Christian Holy Land from Muslim occupation. They encountered a consistent, Eastern approach to the architectural expression of the Christian faith which the physical remains of their churches show they adopted. Previously, I have shown how it can be deduced from the archaeological remains of churches from the 4th-6th C that early church architecture was influenced by the theological ideas of the period. This paper argues that the Eastern approach to church architecture as adopted by the Crusaders was compatible with the medieval European theological context and can be seen as a legitimate expression of medieval theology.<br />

Strategic significance of the island state of Sri Lanka

The study is focused on an analysis of the major diplomatic documents from the mid eighteenth century to the present as regards Sri Lanka, or Ceylon as it was known till 1972. The objectives of the study are to identify the issues underlying these diplomatic documents. These include the political and strategic factors and other subsidiary issues like trade and commerce relevant at the time these treaties, agreements, and proposed treaties were formulated. It is also a geopolitical study as it relates to Sri Lanka's geographical position in the Indian Ocean, and her possession of the Trincomalee Harbour on its east coast, which is one of the great natural harbours of the world. Over the centuries this harbour has had significant strategic value for naval deployments. The case study of the eighteenth and nineteenth centuries studies the diplomatic documents against the political and strategic background for the French Revolution and actions of Napoleon, and the Anglo/French rivalry, spreading from Europe to North America and Asia. In the twentieth century the environment for studying the place of Sri Lanka in the Indian Ocean was created by the Russian Revolution, the failure to keep the peace of Versailles after World War I, the conflict and horrors of World War II which led to the disintegration of European colonial empires in Asia and Africa, and the tensions generated by the Cold War. A study of the documents would reveal that in international relations what matters is the ability of a party to promote its interests, and this depends on its power. This realist approach contrasts to the idealist approach where policies are based on moral and ethical principles. For the realist the states should follow to protect their interests and to survive. To achieve this is to strive for a ‘balance of power’. To do so is to form a favourable alliance system. As the documents examined cover a period from the mid-eighteenth century to the later part of the twentieth century, they reflect the changing technologies that have had an influence on naval and military matters. For example, this period witnessed great changes in technology of energy utilized to propel warships, from wind, to steam, to fuel and finally to nuclear power. These changes had an influence in determining strategic policies involving weapon systems and communications within a global and regional setting. The period covered was the beginning of the process described a ‘globalisation’. Its idea is not unique to this century; there were many attempts, in various times of history, to integrate societies within a global context. Viewed in this light, the Anglo-French rivalry of the eighteenth and nineteenth centuries was the indication of a global naval strategy, in which Sri Lanka was a major factor in the Indian Ocean region. This process was associated with the phenomena called the ‘expansion of Europe’. It covered all the oceans of the world and in the nineteenth and twentieth centuries led to the founding of the largest maritime empire the world has ever seen: The British Empire. After World War I, the British naval strength (the basis of the British Empire) and her consequent position as a great power, was challenged by other powers like the United States of America and Japan. After World War II, the US Navy was supreme: and there was a close alliance between Britain and the USA. The strength of the US/British alliance was based on the navy and its bases, which were spread throughout the globe; to project power, and act as deterrence and balancing force. Sri Lanka, due to her strategic position, was a part of this evolving process, and was tied to a global strategy (with its regional connotations) from the eighteenth century to the present.

Ecology of Pittosporum undulatum Vent. (Pittosporaceae) an environmental weed in south east Australia

Pittosporum undulatum Vent. (Sweet Pittosporum) is a densely foliaged tall shrub or small tree, native to the wet forests of south east Australia, This species now functions as a serious environmental weed in a range of habitats in Australia and on other continents and islands throughout the temperate, sub-tropical and tropical zones. This study investigated some of the ecological causes and consequences of P. undulatum invasion across a range of habitat types in south east Australia. Key aspects of P. undulatum biology and ecology investigated in the current study include; patterns of morphological variation across the range of habitats occupied (as a measure of the species’ plasticity), dispersal ecology and seed germinability, population structure and spatial pattern, community relationships and the ecological impacts of invasion. Phenotypic plasticity is considerable in P. undulatum. No clear patterns of geographic variation emerged from a study of leaf morphological attributes across the current range of this species on mainland south east Australia. The pattern of morphological variation is particularly complex in Victoria, where the invasion of this species is most advanced. The species’ adaptability to a range of environments and environmental conditions will likely promote further range expansion. The abundant winter fruit crop produced by functionally female P. undulatum plants attracts a suite of generalist opportunistic frugivores, which feed on P. undulatum fruits and seeds at various stages of fruit dehiscence, thereby enhancing dispersal opportunities for this species. P. undulatum seed collected from natural and invasive populations, at two stages of fruit maturity and from the scats and pellets of dispersal agents, displayed high germinability. European Blackbirds and Pied Currawongs are implicated as the main avian dispersal agents of P undulatum in south east Australia. The broader ecological implications of developing relationships between invasive fleshy-fruited bird-dispersed plant species and adaptive frugivores are likely to be considerable. The distribution of P. undulatutn seedlings was significantly negatively correlated with adult conspecifics and significantly positively correlated with trees and shrubs of other genera. This pattern reflects the importance of both firugivorous dispersal agents and the species’ germination and establishment requirements, in shaping the contagious distribution pattern typical of this species. These analyses suggest that recruitment opportunities for conspecific seedlings are limited beneath the canopy of adult conspecifics. Densities of P. undulatum were on average, 2.7 times higher in invaded populations, compared to the natural populations sampled. A male-bias was evident in all populations and no relationships between reproductive activity and the density of seedlings and juveniles were evident. Invading populations of P. undulatum impose substantial changes on ecosystem-level properties and functions. Mean species richness and cover-abundance declined notably once P. undulatum cover-abundance exceeded 20% at the invaded sites and 60% at the natural sites sampled. The natural communities sampled displayed comparatively greater resilience to the competitive effects of P. undulatum, but community attributes were affected at high densities and cover-abundance of this species. The cover-abundance of herbs and grasses declined most substantially with increasing P. undulatum at invaded sites, whereas, at the natural sites sampled, the species’ structural analogues appeared to be most affected by increasing P. undulatum cover-abundance. This study has demonstrated that the ecological consequences of P. undulatum population expansion are substantial and contribute to changes in the composition and successional trajectory of affected communities. These processes ultimately lead to the loss and simplification of biodiversity values and the homogenisation of affected habitats. P. undulatum has the potential to emerge as one of south east Australia's most serious environmental weed species.

Population genetic structure of serotine bats (Eptesicus serotinus) across Europe and implications for the potential spread of bat rabies (European bat lyssavirus EBLV-1).

Understanding of the movements of species at multiple scales is essential to appreciate patterns of population connectivity and in some cases, the potential for pathogen transmission. The serotine bat (Eptesicus serotinus) is a common and widely distributed species in Europe where it frequently harbours European bat lyssavirus type 1 (EBLV-1), a virus causing rabies and transmissible to humans. In the United Kingdom, it is rare, with a distribution restricted to south of the country and so far the virus has never been found there. We investigated the genetic structure and gene flow of E. serotinus across the England and continental Europe. Greater genetic structuring was found in England compared with continental Europe. Nuclear data suggest a single population on the continent, although further work with more intensive sampling is required to confirm this, while mitochondrial sequences indicate an east-west substructure. In contrast, three distinct populations were found in England using microsatellite markers, and mitochondrial diversity was very low. Evidence of nuclear admixture indicated strong male-mediated gene flow among populations. Differences in connectivity could contribute to the high viral prevalence on the continent in contrast with the United Kingdom. Although the English Channel was previously thought to restrict gene flow, our data indicate relatively frequent movement from the continent to England highlighting the potential for movement of EBLV-1 into the United Kingdom.
