Mutually assured destruction or co-dependence? The G20 and the UN

The G20 forum has acted to crystallise important changes in the architecture of global governance emerging since the 1970s. This has seen the locus of power shift away from the United Nations (UN) System as smaller and poorer states become increasingly adept at exercising their power within UN structures. Yet it is too simple to set the G20 against the UN, for example as minilateralism versus multilateralism. While the UN seems increasingly constrained and less relevant, it is not about to disappear. Moreover, we argue there are two significant obstacles to the G20 claiming the mantle of dominant global governance institution. First, that minilateralism is still a form of multilateralism, and ultimately subject to the same problems with the generation of consensus if extended, as in the G20, to include sufficiently diverse state members for a claim of legitimacy. Second, its emergence from the Global Financial Crisis and historical focus on financial governance means its agenda is excessively narrow at a time when food and environmental crises command similar global political significance. We conclude by considering some of the different elements of the emerging G20/UN dynamic, and whether this emerging dialectic can enhance prospects for wide ranging reforms to global trade, finance and economic structures that are currently incapable of functioning sustainably or preventing wide scale famine.

The Dresden firebombing : memory and the politics of commemorating destruction

The firebombing of Dresden marks the terrible apex of the European bombing war. In just over two days in February 1945, over 1,300 heavy bombers from the RAF and the USAAF dropped nearly 4,000 tonnes of explosives on Dresden's civilian centre.Since the end of World War II, both the death toll and the motivation for the attack have become fierce historical battlegrounds, as German feelings of victimhood complete with those of guilt and loss. The Dresden bombing was used by East Germany as a propaganda tool, and has been re-appropriated by the neo-Nazi far right. Meanwhile the rebuilding of the Frauenkirche- the city's sumptuous eighteenth-century church destroyed in the raid-became central to German identity, while in London, a statue of the Commander-in-Chief of RAF Bomber Command, Sir Arthur Harris, has attracted protests. In this book, Tony Joel focuses on the historical battle to re-appropriate Dresden, and on how World War II continues to shape British and German identity today.

Covalent/crystallite cross-linked co-network hydrogels : an efficient and simple strategy for mechanically strong and tough hydrogels

Covalent/crystallite cross-linked co-network hydrogels have been prepared using epoxy and PVA through a cyclic freezing-thawing process. The PVA/epoxy hydrogels show enhanced mechanical strength and toughness. PVA/epoxy hydrogels with 4 wt% epoxy loading display maximum tensile strength and toughness of 1.1 MPa and 2838 kJ/m3 respectively. The fracture toughness of PVA/epoxy hydrogels ranges from 160 to 450 J/m2. Radius of gyration and fractal information of the hydrogels were obtained by fitting the SAXS data to the Guinier and power law models. The enhanced mechanical properties are attributed to the increase in covalent bonding and decrease in crystallite distribution with an increase in epoxy content. However a larger hysteresis is shown for PVA/epoxy hydrogels due to irreversible destruction of covalent bonds between epoxy and PVA.
