Mr Secrets and Social Media: the Confession of Richard Rodriguez
No full textRichard Rodriguez's works create troubling situations for many scholars. Though numerous critics see him as the penultimate Chicano writer, many others see his writing as only pandering to the elite. However, all politics and controversies aside, he is a writer whose ideas upon language and public confession have been revolutionary. Throughout the thesis, I argue that Rodriguez's ideas upon language and identity are applicable to the social media landscape that we reside in currently, especially the public confession. Also, I use deconstructionism, along with postmodern criticism, to illustrate the changing arc of Rodriguez's confession from his first autobiography to his final one. In his first memoir, Rodriguez remains in the closet upon his sexuality, and the reader only catches glimpses of the 'real' character inside his work. In the second memoir, the reader sees a better glimpse because of his coming out; yet, even in this regard, he does not do so wholly and still leaves his confession unfinished. By the third, he applies themes and problems seen in his first and second works to discuss our browning nature, and how we are all sinners and that we desire to confess our sins. In my assessment of Rodriguez, I argue throughout all my chapters upon a measure of irreconcilability between the private world of the Hispanic immigrant family and the public sphere that they are forced to inhabit because of his citizenship and education. This irreconcilability creates a drastic limiting of identity for the author that Rodriguez is forced to navigate which creates his desire for confession
Factors that foster Latina, English language learner, non-traditional student resilience in higher education and their persistence in teacher education
No full textDoctor of PhilosophyCurriculum and Instruction ProgramsMargaret G. ShroyerThis qualitative case study focused on 11 non-traditional, ELL, Latinas within a community-based, teacher education program. The purpose of the study was: (a) to explore the various internal characteristics and external factors that foster Latina, English language learner (ELL), non-traditional students’ resiliency in reaching and remaining in college and (b) to determine what ways these internal characteristics and external factors influenced participants’ desire to pursue and ability to persist in teacher education. The researcher utilized two primary sources of data, (1) an autobiographical, qualitative survey, and (2) individual in-depth, semi-structured interviews. As a secondary source, the researcher used academic documents to provide context for student success in the program.
The internal characteristic of sense of purpose and a future (demonstrated in participants’ determination, identity, and responsibility) proved to be most protective for participants’ resiliency. Caring relationships (with the features of: consejos (advice or homilies), quality not quantity, and high expectations in the context of care) proved to be the most significant external factor for fostering participant resiliency. The study also identified the overarching emergent theme of advocacy inspired by hardship found among participant discourse. Within this theme, findings indicated that, as a result of their cultural and experiential understandings, participants were able to enact culturally responsive teaching with their Latino/a students. Furthermore, participants demonstrated a strong sense of agency to improve the education outcomes of culturally and linguistically diverse (CLD) students and a desire to advocate specifically on behalf of ELL Latino/as students
Personal Agency Inspired by Hardship: Bilingual Latinas as Liberatory Educators
No full textThis qualitative multiple case study focused on eleven non-traditional, bilingual, Latinas within a teacher education program. The study explored various factors that influenced participants’ desire to pursue and ability to persist as pre-service teachers. The overarching theme identified among participant discourse was personal agency inspired by hardship. Findings indicated that, as a result of their cultural and experiential understandings, participants enacted culturally responsive teaching with their Latino/a students. Furthermore, participants demonstrated a strong sense of personal agency to improve the educational outcomes of culturally and linguistically diverse students and a desire to advocate specifically on behalf of English learner Latino/a students

No full textMichelle L. Farrell is a contributing author, “Jessica Rodriguez’: Espejuelos Oscuros”.
Book description: With the recent shift in Cuba-US relations stemming from the relaxing of travel restrictions and an influx of American visitors, interest in Cuba and its culture has increased substantially. A new emphasis has been placed on the island country’s many cultural and artistic achievements, specifically in film. Cuban cinema is recognized around the world as having produced some of the most celebrated works originating from Latin America—such as Fresa y Chocolate and La Muerte de un Burócrata—as well as many prominent artists—including directors Tomás Gutiérrez Alea and Humberto Solás. In A Cuban Cinema Companion, editors Salvador Jimenez Murguía, Sean O’Reilly, and Amanda McMenamin have assembled a collection of essays about more than 100 films across six decades, including feature films, documentaries, and animation. These entries also provide information on directors, actresses, and actors of Cuban cinema. Entries range from films like Retrato de Teresa to Buena Vista Social Club and include descriptions of each film’s plot, themes, and critical commentary, as well as comprehensive production details and brief suggestions for further reading.https://digitalcommons.fairfield.edu/modernlanguagesandliterature-books/1017/thumbnail.jp
Open data barometer global report
No full textHighlights the lack of open and accessible data on the performance of key public services. If the political and social impacts of open data are to be realised, work to increase the supply of datasets from right across government will be needed, alongside sustained investment in capacity building, training and support for effective data use.
Introduction
The core idea behind Open Government Data (OGD) is a simple one: public data should be a shared resource. Making data open is valuable not only for the government departments that collect and release the data, but also for citizens, entrepreneurs and other parts of the public sector.
The implementation of OGD takes dedicated and sustained policy attention. Affecting widespread impact through the release of OGD relies not only upon the supply of high-quality data, but also upon the capacity of users to work with the data, and the ability of government to engage proactively with those users.
In our complex world, access to OGD has the power to secure enhanced government accountability, empower coordinated action to improve public services and civil society, and inspire new business ideas. Yet far too often, access to data, along with the skills to understand and make use of it, are distributed unequally, and would-be users frequently encounter unnecessary technical and legal restrictions that prevent data re-use. Calls for a “Data Revolution” — led by the United Nations — have placed renewed attention on ensuring the collection and management of high-quality data around the world through strengthened statistical capacity, and are driving a focus on the use of new “big data” resources in policy making. Against this backdrop, questions concerning who has access to data, and whether citizens have the capability and freedoms to create, access, and analyse data about their own communities and concerns, become ever more important for securing a fair balance of power in our societies
Fast and inexpensive synthesis of pentacene with high yield using 6,13-pentacenequinone as precursor
No full textPentacene is an important semiconductor in the field of organic electronics. In this work is presented an alternative synthesis procedure to obtain pentacene from 6,13-pentacenequinone as a precursor. Synthesis of pentacene was performed in two reactions, Diels-Adler cycloaddition of 6,13-pentacenequinone followed by 6,13-pentacenequinone reduction to pentacene, employing LiAlH4 as reducing agent. The products were characterized by Fourier Transform Infrared Spectroscopy (FTIR), 1H-Nuclear Magnetic Resonance Spectroscopy (1H-NMR), X-Ray Diffraction (XRD), Thermogravimetric Analysis (TGA) and Ultraviolet–Visible Spectroscopy (UV-VIS). In this work, 6,13-pentacenequinone was synthetized with a high yield (55%) using an alternative method. The optimization process resulted in an overall reduction of reaction time while exhibiting high yield. The method presented here provides an affordable pentacene synthesis route with high purity, which can be further applied for research and development of organic electronic applications

No full textilustraciones, fotografías (principalmente a color), mapasEl trabajo presenta la evaluación de la fracción liposoluble del polen apícola y sus extractos de muestras provenientes de tres zonas del departamento de Cundinamarca en dos épocas del año. Se incluyo dentro de los análisis la caracterización palinológica, el análisis proximal, el perfil de ácidos grasos y contenido de vitamina E de las muestras de polen apícola y los extractos obtenidos por metodologías convencionales y no convencionales.
A través de una metodología cromatográfica se realizó la determinación del perfil de carotenoides. Los resultados diversos en los análisis fisicoquímicos y palinológicos mostraron la influencia de las diferentes épocas (lluvia y de sequía) en la disponibilidad de las familias botánicas. En general, el análisis proximal arrojo que las muestras tienen unos contenidos de humedad de 9,1 ± 1,9%, cenizas 2,7 ± 0,3%, fibra 9,1 ± 1,9% y proteína bruta 27,1 ± 1,7%. Se determinaron las condiciones adecuadas para la extracción convencional (8 días de extracción) y por ultrasonido (34% de potencia por 14 minutos) empleando aceite comestible como solvente, las cuales junto con la extracción con fluidos supercríticos permitieron la obtención de extractos ricos en la fracción liposoluble del polen apícola. La técnica de cromatografía liquida de alta resolución (HPLC) empleo una fase reversa con columna C30 y una fase móvil polar con gradiente de metanol: agua: tert butil metil éter. Esta técnica permitió la separación e identificación de los carotenoides presentes en las muestras de polen y en los extractos oleosos, se pudo identificar que estos son fuentes potenciales de estos compuestos bioactivos, siendo el carotenoide más abundante la β-criptoxantina. (Texto tomado de la fuente)The work presents the evaluation of the fat-soluble fraction of bee pollen and its extracts from samples from three areas of the department of Cundinamarca at two times of the year. Included within the analyzes are the palynological characterization, the proximal analysis, the fatty acid profile and vitamin E content of the bee pollen samples, and the extracts obtained by conventional and unconventional methodologies. Through a chromatographic methodology, the carotenoid profile was determined. The diverse results in the
physicochemical and palynological analyzes showed the influence of the different seasons (rainy and dry) on the availability of the botanical families. In general, the proximal analysis showed that the samples had moisture contents of 9.1 ± 1.9%, ashes 2.7 ± 0.3%, fiber 9.1 ± 1.9% and crude protein 27.1 ±1.7%. The appropriate conditions were determined for conventional extraction (8 days of extraction) and by ultrasound (34% power for 14 minutes) using an edible oil as solvent, which together with the extraction with supercritical fluids
allowed obtaining extracts rich in the fat-soluble fraction of bee pollen. The high performance liquid chromatography (HPLC) technique uses a reverse phase with a C30 column and a polar mobile phase with a gradient of methanol: water: tert-butyl methyl ether. This technique allowed the separation and identification of the carotenoids present in the pollen samples and in the oily extracts, it was possible to identify that these are potential sources of these bioactive compounds, the most abundant carotenoid being β cryptoxanthinMaestríaMagister en Ciencia y Tecnología de AlimentosCalidad de Alimento

Reason: Author requested closed access (OA after 2yrs) in Vireo ETD systemConventional narratives of American literary history lead us to believe that most women writers at the turn into the twentieth century abandoned the themes of domesticity and true womanhood that typified the writings of their nineteenth-century foremothers. On the contrary, as this dissertation argues, white writers often drew characters that use domesticity to colonize Indian and Mexican women, usually to legitimize their own public activities. Moreover, I show how Indian and Mexican-American women writers manipulate domestic rhetoric to assert a syncretic domesticity that negotiates resistance and assimilation. Interpreting memoirs, novels, Indian boarding school essays, Mexican-American cookbooks, and the visual culture that surrounds their publication, I argue that such responses were in no way isolated or exceptional, nor were they merely responses. Native and Latina women collectively rewrite colonial domesticity and write their own domesticity.Item withdrawn by Mark Zulauf ([email protected]) on 2013-03-14T20:06:59Z

Physiological color change in the blue-fronted dancer damselfly: the control and function of color change in Argia apicalis males (Odonata: Zygoptera: Coenagrionidae)
No full textSeveral studies have established the existence of temperature-controlled physiological color change (PCC) in Odonata species. Individuals capable of this PCC darken to “dark-phase” (DP) coloration below a temperature threshold and return to “bright-phase” (BP) coloration once above it. The stimulus controlling PCC in Argia apicalis (Say) has been contentious since first studied in the 1960s, as BP and DP males are often present under seemingly identical conditions. In Chapter 1, my goal was to determine if the control of A. apicalis male PCC could be attributed to one specific variable or if it is dual-controlled. I first tested whether ambient temperature can be used to predict color phase and found that it is a significant predictor of DP coloration in solitary males only. I next looked for an association between DP coloration and mating status (mating or solitary) and found that DP is far more likely to be exhibited by mating males, thus PCC is also mating-controlled in A. apicalis males. Finally, I looked for a relationship between mating stage and color phase and established that matingcontrolled PCC is initiated during copulation, further supporting the link between mating and PCC. Additionally, males were darkest during oviposition—the mating stage when males may be most vulnerable to predation. My results indicate that A. apicalis males possess dual-controlled PCC. In Chapter 2, my objective was to establish whether DP coloration could be operating as an anti-predator defense strategy in A. apicalis males. I first measured the reflectance spectra of DP and BP males and found that BP males are approximately 4.8 times brighter than DP males. I subsequently performed a binary choice experiment to determine whether BP males suffer higher levels of predation than DP males. I tested two predator groups for their color phase preference: avians, Gallus gallus domesticus (Linnaeus), and anurans, Lithobates clamitans melanota (Rafinesque) and Lithobates catesbeianus (Shaw). I found that both groups attacked significantly more BP than DP models, so it is plausible that the mating-controlled PCC exhibited by A. apicalis males could be functioning as an anti-predator defense strategy during ovipositionPh.D.Includes bibliographical referencesby Amanda Marie Whispel
