Sources of Chicano Art: Our Lady of Guadalupe

There have been two main streams of influence on Chicano artists aside from the obvious one that is the result of their artistic training, education and development in the United States. The primary influence came from Mexico, first during the colonial period in the form of New Spanish art and architecture, and then in modem times provided by the Mexican muralists through their work and their use of pre-Columbian art. The New Spanish materials formed the nucleus for the second stream of influence composed of the various manifestations of religious folk art found primarily in the Southwest

Relational Aggression, Middle School Girls, and the Development of Critical Consciousness

This study, Relational Aggression, Middle School Girls, and the Development of Critical Consciousness, engaged both feminist theory and critical pedagogy as a means to deconstruct the issue of relational aggression among adolescent girls. The objective of this research was to contribute to the growing body of literature pertaining to relational aggression and fill some gaps in the literature surrounding preventative programming. This study investigated the experiences of middle school girls engaged in a solution- oriented approach in order to postulate possible program approaches and educational initiatives to decrease the prevalence of relational aggression in middle school girls. The collection and analysis of the data sought to describe a connection between girls’ participation in the program and developing critical consciousness about relational aggression, as well as strategies to address it in their lives. The qualitative data collected in this participatory action research show that relational aggression is much more than a mere “right of passage” or indicate that “mean girls” are a just a normal part of growing up. Relational aggression is harmful, has intense, negative short- and long-term effects, and—in the lives of the girls I have worked closely with—is very real, incredibly painful, and deeply personal. The findings of this study confirmed that girls benefit from the creation of educative environments, or “safe spaces,” where they can dialogue critically with one another about issues that are important to them; this is integral to their socioemotional development in middle school

Development of methods to study plant-parasitic nematode chemotaxis and the effect of ILeVO and VOTiVO seed treatments on the soybean cyst nematode, Heterodera glycines

Nematode-protectant seed treatments for controlling the soybean cyst nematode, Heterodera glycines, have been introduced for integration into existing nematode management plans. Several seed treatments labeled for H. glycines control are currently available, with more expected in the near future. This dissertation describes i) tools to study nematode chemotaxis to chemicals and roots and ii) assessment of two commercial seed treatments, ILeVO (active ingredient: fluopyram) and VOTiVO (active ingredient: Bacillus firmus I-1582), on important H. glycines life processes. The first objective was to develop and test two novel microfluidic chips to study chemotaxis of plant-parasitic nematodes to chemicals (“basic chip”) and roots (“root chip”). Proof-of-concept experiments were conducted with both chips. Several ionic solutions were tested with the basic chip on second-stage juveniles (J2s) of H. glycines and the root-knot nematode, Meloidogyne incognita. There was a differential response of the two nematode species to a number of the ionic solutions. Custom software was written to assist in tracking nematodes in the root chip using a flatbed scanner. The attraction of H. glycines J2s to 3-day-old soybean seedlings (cv. Williams 82) was successfully captured using the root chips over an 18-hour period. The second objective was to assess the effects of ILeVO and VOTiVO seed treatments on several H. glycines life processes. In greenhouse experiments, ILeVO consistently reduced H. glycines reproduction on soybean roots. Seed exudates from ILeVO-treated seeds inhibited hatching and motility of H. glycines J2s, relative to the untreated control. Conversely, radicle exudates from seedlings grown from ILeVO-treated seeds reduced H. glycines hatching modestly in only one experimental run did not affect motility of J2s. In a growth chamber experiment, ILeVO significantly reduced H. glycines root penetration compared to untreated plants at two nematode inoculation levels. In another root penetration experiment, soybeans grown from treated or untreated seeds were inoculated with H. glycines J2s at soil depths of 2.5, 5, or 7.5 cm. ILeVO reduced nematode root penetration only at the 2.5-cm inoculation depth. Nematode behavioral changes in response to exudates from treated and untreated seeds then were assessed using custom software. ILeVO seed exudates significantly reduced speed of H. glycines J2s after two hours of exposure. A flatbed scanner then was used to study the movement of H. glycines populations exposed to seed treatments. Treated and untreated seeds were incubated in well plates for one hour before removal with clean forceps and insertion of H. glycines J2s. The percentage of the H. glycines populations that moved over a critical threshold distance (300 μm) in the wells were evaluated every hour for 24 hours using another custom software program. ILeVO significantly reduced population movement relative to the untreated control. And H. glycines J2s in wells that had a seed, treated or not, had significantly less movement compared with the blank control. Overall, the results suggest that ILeVO affects multiple life processes of H. glycines. VOTiVO did not consistently affect any of the variables measured in the experiments

Reflexiones de Edmundo O'Gorman sobre la significación del triunfo de la República

Martín Quirarte reflexiona sobre la aptitud crítica y el valor documental de la obra de Edmundo O'Gorman. De esta forma, analiza "El triunfo de la república en el horizonte de su historia", colaboración del mismo en el libro A cien años del triunfo de la república. Quirarte considera que el texto logra trascender la historiografía tradicional, evita las censuras y las concesiones y otorga magnitud y sentido plenos a la victoria de la República: derrotar tanto al enemigo externo como al interno y permitir a México cobrar su ser como nación

Historia política: siglo XIX

El propósito de este ensayo es dar una visión impresionista de la forma en que se ha tratado la historia política del siglo XIX en los últimos 25 años. Inútil es decir que no tiene pretensiones eruditas y aún cuando las tuviese sería imposible expresar demasiado en unas cuantas páginas. Como este trabajo no es un resumen bibliográfico, faltan figuras que a juicio de ciertos lectores podrán ser consideradas como representativas de una tendencia o de una doctrina. Las omisiones que se encuentren se explican por la falta de espacio y no como fruto de una mala intención
