Freeways and Free Speech, Rail Cars and Rancheras: Geographic and Linguistic Mobility in Contemporary Mexican and Mexican-American Cultural Production

This dissertation considers mobility in contemporary Mexican and Mexican-American cultural production (1960s-2000s) and specifically demonstrates how characters utilize creative language to induce an alternate mobility in instances when geographic movement is limited, coerced, or impossible. The analysis of novels and plays highlights the possibilities of human agency via deployments of voice (poetry, song, code-switching, storytelling, parody, and protest, among others). These deployments allow characters to move emotionally to desired places and, in certain situations, to participate in larger social movements against injustices. The first chapter centers on the use of music and poetry as an alternate way of moving in two plays by Hugo Salcedo, El viaje de los cantores (1990), based on the lives of male migrants who die in a boxcar on their journey to the US, and Sinfonía en una botella (1990), on Mexican citizens who attempt to cross the border in automobiles only to find themselves stuck in gridlock traffic. Chapter 2 considers what I term "narrative motion" in Carlos Morton's play Johnny Tenorio (1983) in which a Chicano Don Juan code-switches, and in María Amparo Escandón's González and Daughter Trucking Co. (2005) in which truck-driving protagonist Libertad tells stories to her fellow inmates. The third chapter analyzes what I call "vocal derailments" through the use of orality and parody in Emilio Carballido's play, Yo también hablo de la rosa (1966), and his novella, El tren que corría (1984). Chapter 4 considers the connection between creative language and action in the farmworker movement by analyzing the use of the künstlerroman (artist's) genre in ...y no se lo tragó la tierra (1971) by Tomás Rivera and Under the Feet of Jesus (1995) by Helena María Viramontes. I demonstrate the way the works underscore the need for artists in the movement to continually move against injustice in the fields. This study adds to studies on migration and literature by highlighting the diversity of (im)mobile experiences in Mexican and Mexican-American cultural production and by signaling the possibilities of the tactical voice for those in limiting circumstances on both sides of the border

Multiplicity of nuclear dust lanes and dust lane shocks in the Milky Way bar

Aims: We show the existence of a small family of inner-galaxy dust lanes and dust lane standing shocks beyond the two major ones that were previously known to exist Methods: We analyze images of CO emission in the inner regions of the Galaxy Results: The peculiar kinematics of the major dust lane features are repeated in several other distinct instances at l > 0deg, in one case at a contrary location 100 pc above the galactic equator at l > 3degr at the upper extremity of Clump 2. Like the previously-known dust lanes, these new examples are alsoassociated with localized, exceptionally broad line profiles believed to be characteristic of the shredding of neutral gas at the standing dust lane shocks. Conclusions: There may be secondary dust lane and standing shocks in the Milky Way bulge. The vertical structure provides a temporal sequence for understanding the secular evolution of gas flow in the bar

Measuring the Reliability of a Gamified Stroop Task:Quantitative Experiment

Background: Few gamified cognitive tasks are subjected to rigorous examination of psychometric properties, despite their use in experimental and clinical settings. Even small manipulations to cognitive tasks require extensive research to understand their effects. Objective: This study aims to investigate how game elements can affect the reliability of scores on a Stroop task. We specifically investigated performance consistency within and across sessions. Methods: We created 2 versions of the Stroop task, with and without game elements, and then tested each task with participants at 2 time points. The gamified task used points and feedback as game elements. In this paper, we report on the reliability of the gamified Stroop task in terms of internal consistency and test-retest reliability, compared with the control task. We used a permutation approach to evaluate internal consistency. For test-retest reliability, we calculated the Pearson correlation and intraclass correlation coefficients between each time point. We also descriptively compared the reliability of scores on a trial-by-trial basis, considering the different trial types. Results: At the first time point, the Stroop effect was reduced in the game condition, indicating an increase in performance. Participants in the game condition had faster reaction times (P=.005) and lower error rates (P=.04) than those in the basic task condition. Furthermore, the game condition led to higher measures of internal consistency at both time points for reaction times and error rates, which indicates a more consistent response pattern. For reaction time in the basic task condition, at time 1, rSpearman-Brown=0.78, 95% CI 0.64-0.89. At time 2, rSpearman-Brown=0.64, 95% CI 0.40-0.81. For reaction time, in the game condition, at time 1, rSpearman-Brown=0.83, 95% CI 0.71-0.91. At time 2, rSpearman-Brown=0.76, 95% CI 0.60-0.88. Similarly, for error rates in the basic task condition, at time 1, rSpearman-Brown=0.76, 95% CI 0.62-0.87. At time 2, rSpearman-Brown=0.74, 95% CI 0.58-0.86. For error rates in the game condition, at time 1, rSpearman-Brown=0.76, 95% CI 0.62-0.87. At time 2, rSpearman-Brown=0.74, 95% CI 0.58-0.86. Test-retest reliability analysis revealed a distinctive performance pattern depending on the trial type, which may be reflective of motivational differences between task versions. In short, especially in the incongruent trials where cognitive conflict occurs, performance in the game condition reaches peak consistency after 100 trials, whereas performance consistency drops after 50 trials for the basic version and only catches up to the game after 250 trials. Conclusions: Even subtle gamification can impact task performance albeit not only in terms of a direct difference in performance between conditions. People playing the game reach peak performance sooner, and their performance is more consistent within and across sessions. We advocate for a closer examination of the impact of game elements on performance.</p

Decision-making regarding place of birth in high-risk pregnancy: a qualitative study

Introduction: Women consider factors including safety and the psychological impact of their chosen location when deciding whether to give birth in hospital or at home. The same is true for women with high-risk pregnancies who may plan homebirths against medical advice. This study investigated women’s decision-making during high-risk pregnancies. Half the participants were planning hospital births and half were planning homebirths. Methods: A qualitative study using semi-structured interviews set in a hospital maternity department in the UK. Twenty-six participants with high-risk pregnancies, at least 32 weeks pregnant. Results were analysed using systematic thematic analysis. Results: Three themes emerged: perceptions of birth at home and hospital; beliefs about how birth should be; and the decision process. Both groups were concerned about safety but they expressed different concerns. Women drew psychological comfort from their chosen birth location. Women planning homebirths displayed faith in the natural birth process and stressed the quality of the birth experience. Women planning hospital births believed the access to medical care outweighed their misgivings about the physical environment. Discussion: Although women from both groups expressed similar concerns about safety they reached different decisions about how these should be addressed regarding birth location. These differences may be related to beliefs about the birth process. Commitment to their decisions may have helped reduce cognitive stress

Multiply Folded Graphene

The folding of paper, hide, and woven fabric has been used for millennia to achieve enhanced articulation, curvature, and visual appeal for intrinsically flat, two-dimensional materials. For graphene, an ideal two-dimensional material, folding may transform it to complex shapes with new and distinct properties. Here, we present experimental results that folded structures in graphene, termed grafold, exist, and their formations can be controlled by introducing anisotropic surface curvature during graphene synthesis or transfer processes. Using pseudopotential-density functional theory calculations, we also show that double folding modifies the electronic band structure of graphene. Furthermore, we demonstrate the intercalation of C60 into the grafolds. Intercalation or functionalization of the chemically reactive folds further expands grafold's mechanical, chemical, optical, and electronic diversity.Comment: 29 pages, 10 figures (accepted in Phys.

Midwives\u27 knowledge, attitudes and learning needs regarding antenatal vaccination

Objective: To determine the knowledge, attitudes and learning needs of midwives regarding antenatal vaccination. Design & Setting: A cross-sectional, paper-based survey of midwives employed at the only public tertiary maternity hospital in the Australian state of XX between November 2015 and July 2016. Participants: 252 midwives providing care in antepartum, intrapartum, and/or postpartum settings. Measurements: Self-reported responses to a 41-item survey. Findings: The vast majority of midwives supported influenza and pertussis vaccination for pregnant women, with 90.0% and 71.7% reporting they would recommend pertussis and influenza vaccine, respectively, to a pregnant friend or family member, and almost all stating that midwives should administer vaccines to pregnant patients (94.8%). Seven out of ten midwives (68.1%) responded correctly to all knowledge items regarding vaccines recommended during pregnancy; 52.8% demonstrated correct knowledge regarding vaccine administration despite only 36.6% having attended an education session on antenatal vaccination in the previous two years. Nearly all midwives (97.3%) expressed a need for more education on vaccine administration. The most commonly reported barrier to administering influenza (61.3%) and pertussis (59.0%) vaccination was having staff available with the certification required to administer vaccines. Key Conclusions: Midwives view antenatal vaccination as their responsibility and are interested and receptive to education. Implications for Practice: There is an unmet need and demand among midwives for professional development that would enable them to recommend and administer vaccines to pregnant women in accordance with national immunisation guidelines and integrate vaccination into routine antenatal care
