Electronic Raman scattering in quantum dots revisited

We present theoretical results concerning inelastic light (Raman) scattering from semiconductor quantum dots. The characteristics of each dot state (whether it is a collective or single-particle excitation, its multipolarity, and its spin) are determined independently of the Raman spectrum, in such a way that common beliefs used for level assignments in experimental spectra can be tested. We explore the usefulness of below band gap excitation and an external magnetic field to identify charge and spin excited states of a collective or single-particle nature.Comment: To appear in a special issue of Solid State Communications dedicated to Eli Burstei

The myth of upward mobility

The idea of upward mobility—that anyone who works hard, obeys the law, and saves his money can get ahead—is deeply engrained. From Horatio Alger stories to current Hollywood productions and TV programs, America pays homage to the tale of the hard working, upward striving youth who starts out poor but overcomes obstacles, opens a business, invents a machine, marries well, and ends up in a social class many stations higher than the one in which he or she began

Coalition-proof supply function equilibria under capacity constraints

Whereas in the absence of capacity constraints the Cournot outcome is the unique coalition-proof supply function equilibrium outcome, the presence of capacity constraints may enlarge the set of equilibrium outcomes. Interestingly, if capacities are sufficiently asymmetric the new equilibrium prices are below the Cournot price. These results have important implications for merger and privatization policies: specifically, capacity divestiture will not necessarily imply lower market prices

[Review of] E. San Juan, Jr. Beyond Post Colonial Theory

This is an important book for many reasons. Much like Michael Omi and Howard Winants\u27 Racial Formation in the United States and San Juan\u27s previous book Articulations of Power in Ethnic and Racial Studies in the US, this latest enterprise captures much of the drama and trauma that inequality of power produces when race, ethnicity and class are knotted at its core

Why Europe is Not Carbon Competitive. Bruegel policy brief 2007/05, November 2007

Summary. Europe specialises more than its main global competitors in industries with relatively high carbon emissions, such as minerals and chemicals, rather than in high-tech industries and services . This would have a real effect on Europe’s competitiveness in a world regulated by carbon pricing schemes such as the EU’s Emissions Trading Scheme – even if other blocs apply them as the EU does. Furthermore, in the absence of fair and undistorting carbon pricing schemes worldwide, there is a real risk that business will resort to regulatory arbitrage which will entail a shift in where emissions take place – but no reduction in global emissions. In any case, the issue of which economies are ‘carbon competitive’ will gradually become a much bigger part of the global trade conversation

CARTOGRAFÍAS DEL YO. ESCRITURA AUTOBIOGRÁFICA Y MODERNIDAD EN CENTROAMÉRICA, DEL MODERNISMO AL TESTIMONIO.

This dissertation examines some canonical Central American autobiographical works of the 20th Century. The authors studied include Rubén Darío, Rafael Arévalo Martínez, Froylán Turcios, José Coronel Urtecho, César Brañas, Eunice Odio, Roque Dalton, Miguel Mármol and Rigoberta Menchú. The dissertation maintains that autobiographical writing always interpellates the Other's story and that this interpellation is based in the need to incorporate into modern discourse the social sectors considered "pre-modern." Indigenous people, peasants, women, artisans and workers, oral or illiterate cultures, represent a zone of autobiographical fear and desire. These combined impulses are connected to some cultural peculiarities of the Central American region: mainly, the way in which the rhetoric and practice of Liberalism is adapted by the regional elites from the end of 19th Century onward.After a general overview offered in Chapter 1, this dissertation is divided in three parts that correspond to three different cultural epochs—Modernismo (Chapters 2, 3, 4), Vanguardia (Chapters 5 and 6), and Postvanguardia y testimonio (Chapters 7 y 8). In Modernista autobiography the class-racial-ethnic Other appears as something that "haunts" the traditional, representing both an object of fear and a limit to a Eurocentric concept of modernity. In contrast, the Vanguardista autobiography emphasized its desire of the Other. This general desires for "incorporate" the (national) Other is linked to the foundational /nationalist emphasis that the avant-garde showed in Central America. However, Liberalism never incorporated fully the utopian social models of the Vanguardistas. Due to the crisis of both the Liberal rhetoric and Vanguardista cultural projects, during the 1960s and 1980s the aesthetic-ideological project of the Vanguardia suffered a radicalization. One of the main outcomes was the popularization of testimonio, which has become the most analyzed form of Central American autobiographical writing today. In testimonio the Other and his/her cultural model (basically, orality) and the Gemeinschaft of rural community become embodied as a counter-hegemonic voice that seeks to interpellate the cultural models of the "lettered city" and modernity from a subaltern location
