N=2 Coset Compactifications with Non-Diagonal Invariants

We consider 4-dimensional string models obtained by tensoring N=2 coset theories with non-diagonal modular invariants. We present results from a systematic analysis including moddings by discrete symmetries.Comment: 29 page

Orphans of the Motherland: Puerto Rican Images of Spain in Jacobo Morales\u27s Linda Sara

Puerto Rican identity has been confounded by Puerto Rico\u27s prolonged colonial relationship to Spain (nearly 80 years longer than that of most other Latin American colonies) and its abrupt change in status to that of United States protectorate in 1898 after the Spanish American War. Increasingly, Puerto Rican identity has been theorized in sole reference to the political relationship with the United States. The residual presence of Spain and Spaniards in the construction of the new Puerto Rican collective, and the denial or nostalgia that might still be elicited by the former empire, have gradually receded into the background. Perhaps surprisingly, the presence of Spain and reactions to it find their widest outlet in popular culture. This article analyzes the complex portrayal of the continuing substratum of the Spanish heritage in Puerto Rico in one example from Puerto Rican popular culture—Jacobo Morales\u27s 1994 film Linda Sara. The film\u27s characters either willingly or unknowingly falsify their Spanish past, recounting their (hi)story according to their present needs

Turbulence Time Series Data Hole Filling using Karhunen-Loeve and ARIMA methods

Measurements of optical turbulence time series data using unattended instruments over long time intervals inevitably lead to data drop-outs or degraded signals. We present a comparison of methods using both Principal Component Analysis, which is also known as the Karhunen--Loeve decomposition, and ARIMA that seek to correct for these event-induced and mechanically-induced signal drop-outs and degradations. We report on the quality of the correction by examining the Intrinsic Mode Functions generated by Empirical Mode Decomposition. The data studied are optical turbulence parameter time series from a commercial long path length optical anemometer/scintillometer, measured over several hundred metres in outdoor environments.Comment: 8 pages, 9 figures, submitted to ICOLAD 2007, City University, London, U

The effects of economic crises on participatory democracy

This paper examines the impact of economic conditions on participatory democracy. It analyses whether economic crises affect the types of proposals that emerge from local participatory processes and the fate of these proposals. Focusing on more than 500 proposals that emerged from 34 participatory processes in Spain between 2007 and 2011, our study covers a period which straddles the emergence of severe economic problems resulting from the global financial crisis. Applying four different but complementary analytical strategies, we find two types of effects. First, proposals made during the crisis period were less costly though more challenging. Second, local governments implemented a smaller proportion of the proposals that were put forward by the public. These findings suggest that external economic shocks reduce the ability of governments to respond to the demands of citizens, but that citizens also recalibrate their expectations in response to austerity

Paleomagnetism in speleothems: influence of calcite growth dip on the natural remanent magnetization

Recent studies recognized speleothems as excellent recorders of the Earth’s magnetic field. However, some questions remain about the origin of the natural remanent magnetization and about the influence of the speleothem shape on the recorded magnetic directions.info:eu-repo/semantics/publishedVersio
