Development and the G20
Full text linkThis publication examines what role the G20 can play in international development.
Key findings:
Development is a key component of the G20, but there are concerns over the effectiveness of the current development agenda.
The criticism includes that the development agenda is too diffuse and mostly distant to the G20’s main activities.
But the G20 development agenda has made progress in some important areas, including increasing the resources of the international financial institutions, infrastructure, food security, financial inclusion and reducing the cost of remittances.
However development and global economic issues cannot be treated in isolation; development must be ‘mainstreamed’ and clearly seen as part of the G20’s core agenda.
To the extent that Australia can help strengthen the G20 when it assumes the chair in 2014, and make tangible progress in such areas as - economic growth, financial regulation, trade, financial inclusion, infrastructure and climate change financing – it can make a significant contribution to promoting development and reducing poverty.

The impact of the 1783–1784 AD Laki eruption on global aerosol formation processes and cloud condensation nuclei
Full text linkThe 1783–1784 AD Laki flood lava eruption commenced on 8 June 1783 and released 122 Tg of sulphur dioxide gas over the course of 8 months into the upper troposphere and lower stratosphere above Iceland. Previous studies have examined the impact of the Laki eruption on sulphate aerosol and climate using general circulation models. Here, we study the impact on aerosol microphysical processes, including the nucleation of new particles and their growth to cloud condensation nuclei (CCN) using a comprehensive Global Model of Aerosol Processes (GLOMAP). Total particle concentrations in the free troposphere increase by a factor ~16 over large parts of the Northern Hemisphere in the 3 months following the onset of the eruption. Particle concentrations in the boundary layer increase by a factor 2 to 5 in regions as far away as North America, the Middle East and Asia due to long-range transport of nucleated particles. CCN concentrations (at 0.22% supersaturation) increase by a factor 65 in the upper troposphere with maximum changes in 3-month zonal mean concentrations of ~1400 cm<sup>−3</sup> at high northern latitudes. 3-month zonal mean CCN concentrations in the boundary layer at the latitude of the eruption increase by up to a factor 26, and averaged over the Northern Hemisphere, the eruption caused a factor 4 increase in CCN concentrations at low-level cloud altitude. The simulations show that the Laki eruption would have completely dominated as a source of CCN in the pre-industrial atmosphere. The model also suggests an impact of the eruption in the Southern Hemisphere, where CCN concentrations are increased by up to a factor 1.4 at 20&deg; S. Our model simulations suggest that the impact of an equivalent wintertime eruption on upper tropospheric CCN concentrations is only about one-third of that of a summertime eruption. The simulations show that the microphysical processes leading to the growth of particles to CCN sizes are fundamentally different after an eruption when compared to the unperturbed atmosphere, underlining the importance of using a fully coupled microphysics model when studying long-lasting, high-latitude eruptions

Mechanismen des Korrosionsschutzes plattierter Aluminiumwerkstoffe am Beispiel von Alclad 6025
No full textPlattierte Aluminiumwerkstoffe sind qualitativ hochentwickelte Mehrschichtmaterialverbunde, die aus einer Kemlegierung und einer Plattierung bestehen. Das Kemmaterial erfüllt die Anforderungen an Festigkeit und Lebensdauer des Bauteils. Die Legierungen, die für Plattierungen verwendet werden, sorgen für den Korrosionsschutz unter meist atmosphärischen Bedingungen. Plattierte Aluminiumwerkstoffe finden vor allem Anwendung in der Luftfahrtkonstruktion oder wie Alclad 6025 im Bauwesen als Verkleidung von Fassaden und als Dacheindeckungen.
In der Literatur wird der Korrosionsschutzmechanismus plattierter Aluminiumwerkstoffe allgemein als galvanischer Schutz beschrieben. Wenn eine Beschädigung der Plattierung bis zum Kern reicht, soll sich die elektronegativere Plattierung bevorzugt auflösen und damit die Kemlegierung schützen. Die Plattierungslegierung soll hinreichend korrosionsbeständig sein.
Dabei kann eine leichte allgemeine Korrosion oder Lochkorrosion akzeptiert werden, allerdings mit einer geringen Tiefe, damit die Kernlegierung nicht korrodiert.
Da jedoch keine detaillierten Angaben über den Schutzmechanismus in der Literatur gegeben werden, wurden am Beispiel von Alclad 6025 umfangreiche elektrochemische Untersuchungen sowie Auslagemngsversuche in verschiedenen Atmosphären bzw. Medien durchgeführt. Aus diesen Ergebnissen soll der Schutzmechanismus am Beispiel der Dachplattierung Alclad 6025 genauer beschrieben werden

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
