Abstract

We aimed to compare internal jugular vein and inferior vena cava ultrasonography as predictors of central venous pressure in cirrhotic patients. We performed ultrasound assessments of the internal jugular vein (IJV) and the inferior vena cava and then invasively measured central venous pressure (CVP). We then compared their correlation with CVP and performed area under the receiver operating characteristic curves to determine which had best sensitivity and specificity. IJV cross-sectional area collapsibility index at 30° correlated better with CVP (r 5 20.56, P < 0.001), and an IJV AP-CI at 30° £ 24.8% was better at predicting a CVP ?8 mm Hg, with 100% sensitivity and 97.1% specificity. Thus, IJV point-of-care ultrasound might be superior than inferior vena cava point-of-care ultrasound as a predictor of CVP in cirrhotic patients. [ABSTRACT FROM AUTHOR]

Abstract

Mexico's "Dirty War" or guerra sucia refers to the historical period covering the seventies and early eighties, when the federal governments of presidents Gustavo Díaz Ordaz and Luis Echeverría Álvarez waged open warfare and counterintelligence assaults on urban leftist guerrillas. Once a taboo topic and a historical moment erased and silenced in Mexican historiography, the past fifteen years brought a new wave of historians and activists spearheading attempts at memorializing this bloody event under the frameworks of human rights, archival research, and the recovery of oral history. This research project analyzes three case studies focused on historical and mnemonic reconstructions of guerrilla history and the human rights violations that occurred during the Dirty War; with a particular focus on the two most famous leftist armed movements of that time: the Fuerzas de Liberación Nacional (FLN) and the Liga Comunista 23 de Septiembre (LC23S). The first part delves into Mexico's failed attempt at building a legal framework for transitional justice after Mexico’s “democratic turn” in 2000s. The second case moves to the question of recuperating "spaces of terror" and the successes and failures at building new forms of collective memory. The final chapter focuses on the controversial and infamous murder of Monterrey businessman Eugenio Garza Sada in 1973 and the competing historical and moral interpretations surrounding guerrilla violence. Through a methodology combining discursive analysis, anthropological approaches to memory, and auto-ethnographic vignettes, this dissertation attempts to grasp the current challenges of transforming what once was a marginal countermemory into an accepted and integral part of Mexico's political history. The author expands these questions through the study of guerrilla literature, testimonios, documentaries, and his familial connections to the regional histories of urban guerrillas.

23. Metropolitan Latino Political Behavior: Voter Turnout and Candidate Preference in Los Angeles

Abstract

Most research on Latino voting behavior conclusively finds that as a group, Latinos vote at lower rates than other racial and ethnic groups in the United States. In this article, we argue that given the appropriate circumstances, Latinos should be expected to vote at higher rates than other racial and ethnic groups. In particular, we think the presence of a viable Latino candidate will spur increased Latino turnout and that when Latinos candidates run for office, Latino voters will prefer the co-ethnic candidate. Analyzing precinct level returns from the Los Angeles 2001 mayoral and the 2000 presidential elections we show this may be the case. High-density Latino precincts show higher rates of turnout when Latino candidates are on the ballot, and these same precincts show heightened support for the co-ethnic candidate. In fact, for the first time ever in Los Angeles, the 2001 mayoral election witnessed Latinos voting at the highest rates of any racial or ethnic group in the city.

32. The Dragon Menace: Is China Displacing Mexico's trade with the United States?

Author

Ayala, Edgardo Arturo and Villarreal, Mario

Subjects
*EXPORTS, *EXPORTERS, *ECONOMIC competition
Abstract

The most common statistic used in order to prove China's negative impact on Mexico's trade with the US is the share of US imports precedent from Mexico exporters. This approach suggests that China's expansion in the US market negatively correlates with the growth of the Mexican exports. However, and contrary to conventional wisdom and the ad-hoc shift share approach, our analysis suggest that: 1) even when China displacement effect is not minor, the China expansion in the US market explains at the most one third of the decline in the rate of growth of the Mexican exports to that nation; 2) contradicting the shift share approach that target almost half of the Mexican sectors under the China threat, we localized that almost all the displacement (95 percent) occurred in two sectors, textiles and machinery; and 3) two thirds of the employment losses in the textile industry are explained by long run factors, such as technology, and just one third is due to China's growth in the US market. Moreover, we suggest that the potential for economic gains for Mexico, due to China's economic growth, can offset short-term negative shocks. [ABSTRACT FROM AUTHOR]

Abstract

ZnO + Zn2TiO4 thin films were obtained by the sol–gel method using precursor solutions with different Ti/Zn ratios in the 0.18–2.13 range. The films were deposited on glass substrates and annealed in an open atmosphere at 550 °C. The oxide was characterized by X-ray diffraction and photoacoustic (PA) spectroscopy. The films were constituted of polycrystalline ZnO for the lowest Ti/Zn ratio (0.18), polycrystalline Zn2TiO4 for the 0.70 and 1.0 ratios, and mixes of both oxides for the intermediate ratios (0.32 and 0.50). For the highest ratios studied (1.44 and 2.13), the films were amorphous. The energy band gap (Eg) values were determined from optical absorption spectra, measured by means of the PA technique spectra. Eg varied in the 3.15 eV (ZnO) to 3.70 eV (Zn2TiO4) range.

36. Fictionalizing Juárez : feminicide, violence, and myth-making in the borderlands

Abstract

In the early 1990s, a series of gruesome murders of young women in Ciudad Juárez, a city located in the U.S.-Mexico border, shook the political landscape of Mexico. A decade later, the strange and violent murders, known as the feminicides or feminicidios of Juárez, reached international infamy across hemispheres and continents. During this time, the city and the cases became the subjects of an extensive body of scholarship and of any imaginable artistic medium (narrative, poetry, theater, performance, music, and so on). Eventually, the complexity and overexposure of the cases and the sociopolitical conditions of Ciudad Juárez placed them at the center of a paradoxical debate: on one hand, the work of activists, feminists, and scholars of social sciences (like anthropologists and sociologists) studied the murders as a localized example of a larger phenomenon of mysoginistic violence; on the other, journalistic and media investigations of Juárez understood the murders as the products of specific agents (serial killers, murderers, drug cartels, amongst others) and the fractures within the Mexican Nation-State. And yet, despite the expansion and overlapping of these discourses, fictional representations of Juárez remained tangential to this intricate debate. Thus, this research explores the different ways in which writers, artists, and filmmakers deployed and negotiated existent perspectives on the feminicides within fictional environments. As a result of the vast amount of published work available on Ciudad Juárez, I narrowed the objects of my research through a transnational scope. The resulting sample of texts transverses borders (Mexico and the U.S.), continents (Latin America and Europe), genres (fiction and nonfiction), and mediums (literature and film). The first chapter explores the connections of Sergio González Rodríguez’s Huesos en el desierto and Roberto Bolaño’s 2666 through the theoretical framework of the possible worlds of fiction. The second chapter moves to issues of representation, gender, and race through the analysis of two novels written by Chicana scholars: Alicia Gaspar de Alba’s Desert Blood: The Juárez Murders and Stella Pope Duarte’s If I Die in Juárez. Finally, the third chapter focuses on film representations of Juárez and the feminicides in the form of Gregory Nava’s Bordertown and Carlos Carrera’s Backyard/El Traspatio.
