Strengthening PACs in small Parliaments: perspectives from the Caribbean

Recent efforts to strengthen the oversight capacity of the Parliaments of Jamaica and Trinidad and Tobago have paid particular attention to the public accounts committee (PAC). This chapter provides an analysis of the PACs in both countries. The committees have some similar features in terms of mandate and composition, but both have struggled to be effective, partly because of the difficulties in developing functioning committees in small jurisdictions and partly because of an unhelpful external context. Progress has been made in developing the internal environment of the PACs, but producing and demonstrating significant outputs and outcomes remain a major challenge.

Impact of energy-using product policies

Energy-using products (EuPs), such as domestic appliances, audio-visual and ICT equipment contribute significantly to CO2 emissions, both in the domestic and non-domestic sectors. Policies that encourage the use of more energy efficient products can therefore generate significant reductions in overall energy consumption and hence, CO2 emissions. To the extent that these policies cause an increase the average production cost of EuPs, they may impose economic costs on producers, or on consumers, or on both. In this theoretical paper, an adaptation of a simple vertical product differentiation model – in which products are characterised in terms of their quality and their energy consumption – is used to analyse the impact of the different EuP polices on product innovation and to assess the resultant economic impacts on producers and consumers. It is shown that whereas the imposition of a binding product standard for energy efficiency unambiguously reduces aggregate profit and increases the average market price in the absence of any learning effects, the introduction or strengthening of demand-side measures (such as energy labelling) may reduce, or increase, aggregate profit. Even in the case where the overall impact is unambiguously negative, the effects of product innovation and learning can be in either direction.

The British Army of the Rhine: Turning Nazi Enemies into Cold War Partners

Between 1945 and 1957, West Germany made a dizzying pivot from Nazi bastion to Britain's Cold War ally against the Soviet Union. Successive London governments, though faced with bitter public and military opposition, tasked the British Army of the Rhine (BAOR) to serve as a protecting force while strengthening West German integration into the Western defense structure. Peter Speiser charts the BAOR's fraught transformation from occupier to ally by looking at the charged nexus where British troops and their families interacted with Germany's civilian population. Examining the relationship on many levels, Speiser ranges from how British mass media representations of Germany influenced BAOR troops to initiatives taken by the Army to improve relations. He also weighs German perceptions, surveying clashes between soldiers and civilians and comparing the popularity of the British services with that of the other occupying powers. As Speiser shows, the BAOR's presence did not improve the relationship between British servicemen and the German populace, but it did prevent further deterioration during a crucial and dangerous period of the early Cold War. An incisive look at an under-researched episode, The British Army of the Rhine sheds new light on Anglo-German diplomatic, political, and social relations after 1945, and evaluates their impact on the wider context of European integration in the postwar era.

Molecular mechanisms controlling synaptic recruitment of GluA4 subunit-containing AMPAreceptors

Synaptic recruitment of AMPA receptors (AMPARs) represents a key postsynaptic mechanism driving functional development and maturation of glutamatergic synapses. At immature hippocampal synapses, PKA-driven synaptic insertion of GluA4 is the predominant mechanism for synaptic reinforcement. However, the physiological significance and molecular determinants of this developmentally restricted form of plasticity are not known. Here we show that PKA activation leads to insertion of GluA4 to synaptic sites with initially weak or silent AMPAR-mediated transmission. This effect depends on a novel mechanism involving the extreme C-terminal end of GluA4, which interacts with the membrane proximal region of the C-terminal domain to control GluA4 trafficking. In the absence of GluA4, strengthening of AMPAR-mediated transmission during postnatal development was significantly delayed. These data suggest that the GluA4-mediated activation of silent synapses is a critical mechanism facilitating the functional maturation of glutamatergic circuitry during the critical period of experience-dependent fine-tuning.
