    Notes: We report electromodulated reflectance spectra in n-i-p solar cells with hydrogenated amorphous silicon–germanium alloy absorber layers. At lower photon energies the spectra are determined by bulk electroabsorption, and exhibit peaks near the optical gap of the absorber layers. Voltage scaling of the electroabsorption spectra indicate a built-in potential of Vbi=1.17 V in cells with absorber layer band gaps of 1.50 eV; in conjunction with earlier work, this value argues against a systematic decline in Vbi with an absorber layer band gap. At higher photon energies the spectra are due to direct electroreflectance; the voltage scaling was consistent with model predictions for the electric field at the interface of the p-type and absorber layers. © 2001 American Institute of Physics.

    Notes: We present intensity-modulated photocurrent and infrared transmittance measurements on dye-sensitized solar cells based on a mesoporous titania (TiO2) matrix immersed in an iodine-based electrolyte. Under short-circuit conditions, we show that an elementary analysis accurately relates the two measurements. Under open-circuit conditions, infrared transmittance, and photovoltage measurements yield information on the characteristic depth at which electrons recombine with ions (the "locus of recombination"). For one particular series of samples recombination occurred near the substrate supporting the titania film, as opposed to homogeneously throughout the film. © 2002 American Institute of Physics.

    Notes: To further the understanding of the natural genetic diversity for disease resistance to powdery mildew (Erysiphe cichoracearum) in Arabidopsis thaliana, quantitative trait loci analysis was undertaken on recombinant inbred lines derived from a cross between the resistant accession Warschau-1 and the susceptible Columbia-0. Powdery mildew grew less well on Warschau-1, but the resistance was not associated with a specific block in the infection sequence. Two potential powdery mildew disease-resistance loci were identified and mapped, one with a major effect and one with a minor effect on disease resistance. The two loci acted in an additive manner to confer resistance, and together they explained 65% of the variation in resistance. In addition, the major powdery mildew disease-resistance locus was genetically mapped to the bottom of chromosome III, a region containing the powdery mildew resistance loci RPW7, RPW8 and RPW10. Unlike resistance mediated by the RPW8 locus in the accession Moscow-1, resistance in Warschau-1 was not correlated with the hypersensitive response, highlighting the influence of genetic background or environmental factors on the expression of disease resistance. Together with the powdery mildew resistance loci described in other studies, these results suggest that A. thaliana is a useful source of natural powdery mildew disease resistance, which potentially can be utilized in fundamental studies and as a tool for applied studies.

    Notes: Abstract We review the propagation of energetic partons in hot or cold QCD matter, as known from recent work. We summarize advances in the understanding of both collisional and radiative energy loss. Our emphasis is on radiative energy loss, which has very interesting properties that may help to detect the quark-gluon plasma produced in heavy-ion collisions. We describe two different theoretical approaches, which lead to the same radiated gluon energy spectrum. The case of a longitudinally expanding QCD plasma is investigated. The energy lost by a jet with given opening angle is calculated with the aim of making predictions for the suppression (quenching) of hard jet production. Phenomenological implications for the difference between hot and cold matter are discussed. Numerical estimates of the loss suggest that it may be significantly greater in hot matter than in cold. This makes the magnitude of the radiative energy loss a remarkable signal for quark-gluon plasma formation.

    Notes: Owing to their low bargaining power and high negotiation costs, microstates face severe disadvantages when dealing with the outside world. Forming a group with neighboring nations might be an effective instrument to address this problem. This paper presents a model in which the decision to form, expand or join a regional club is based on negotiation costs and bargaining power rather than on the traditional costs and benefits of trade integration. The model is used to determine the optimal and the equilibrium group size under various entry conditions. The welfare implications of the entry conditions are also examined.

    Notes: This paper examines the economics, politics and political economy of Chile's trade and regional integration (RI) policies, and reaches the following conclusions. First, Chile is likely to obtain static and dynamic benefits from a free trade agreement (FTA) with the US, though the benefits depend crucially on the extent to which its market access to the US improves and on the costs of implementing the intellectual property rights agreement and of enforcing the rules of origin. Second, potential benefits are more doubtful with respect to FTAs with MERCOSUR and the Andean Pact and Central American countries.Third, Chile should complement its ongoing negotiations with the EU by negotiating FTAs with key Asian countries.Fourth, Chile should bind all its tariffs at the WTO at the applied MFN uniform tariff rate. Fifth, the uniform MFN tariff should be reduced below six percent after 2003.

    Notes: This paper draws on Hinkle and Schiff (2003). It analyses the planned Economic Partnership Agreements (EPAs) between the EU and Sub-Saharan Africa (SSA) from a development perspective. It does not take a position on whether SSA should enter into EPAs with the EU. Rather, it starts from the notion that the process of forming EPAs is unlikely to be reversed and examines the conditions that will maximise SSA's benefits from the EPAs. If this notion is correct, then the analysis presented in the paper applies. On the other hand, Pascal Lamy, the EU Trade Commissioner, made a proposal at the May 2004 G-90 summit in Dakar that might lead to a change in the EPA process. He proposed that the G-90, a group consisting of ACP and non-ACP LDC countries, should not have to make concessions at the WTO Doha Round of multilateral trade negotiations, i.e., he proposed a ‘free round’ for the G-90. This proposal opens the door to the possibility that the same might apply to the ACP countries in the EU-ACP negotiations and that the EPA process might be reversed. The paper considers the key issues raised by the planned EPAs, their relationship to the WTO's Doha Round and the EU's Everything-but-Arms Initiative, the changes needed to make the EPAs internally consistent, the domestic reforms in SSA that would need to accompany trade liberalisation in both goods and services, and the potential effects of the EPAs on regional integration in SSA. The EPAs will pose a number of policy challenges for SSA countries, including: restructuring of indirect tax systems, reduction of MFN tariffs, liberalisation of service imports on an MFN basis and related regulatory reforms in the services sector, and liberalisation of trade in both goods and services within the regional trading blocs in SSA. The paper also finds that the EPAs provide an opportunity to accelerate regional and global trade integration in SSA. To realise the potential development benefits of the planned EPAs, two steps are essential. First, the EU must, as it has stated, truly treat the EPAs as instruments of development, subordinating its commercial interests in the agreements to the development needs of SSA. Second, the SSA countries need to implement a number of EPA-related trade policy reforms. However, the latter is far from certain, given the lack of reform momentum in SSA.

    Notes: Labor market integration raises welfare in the absence of distortions. This paper examines labor and goods market integration in a general-equilibrium model with social capital. The findings are: (i) labor market integration has an ambiguous impact on welfare, and raises it if the goods and labor skills are sufficiently different; (ii) compared to Pareto optimum, labor mobility (social capital) is excessively large (depleted); (iii) trade is superior to labor market integration if trading costs are no higher than private migration costs, otherwise the outcome is ambiguous; and (iv) the creation of new institutions in response to labor market integration has an ambiguous impact on welfare.
