Literatura y valores en inglés segunda lengua en el aula de educación secundaria: un proyecto literario sobre la violencia de género

This dissertation seeks to demonstrate that the introduction of a literary project focused on the short story genre written by women writers which have as central theme the problem of gender violence can help students in the Bachillerato stage to develop their key competences as well as their communicative competences, as they work on curricular themes and values such as gender violence and equality. I also intend to prove that a project as the one hereby proposed can increase students’s interest in literature and develop their skills for collaborative work. This study has been theoretically based on Second Language Acquisition (SLA) Communicative Language Teaching (CLLT), Project-Based Language Learning (PBLL), and more specifically, on the use of Literature in the EFL classroom and Feminist Pedagogy with a focus on Secondary Education. This theoretical basis, as well as the curricula Spanish framework is at the core of a project designed to be implemented with Bachillerato students with the objective of using literature as a vehicle to educate against gender violence. This dissertation demonstrates that the EFL classroom is an adequate scenario for this aim because the communicative nature of the subject allows for development both of students communicative competence and critical thinking and values. The results obtained from the partial implementation of this project with real students reveals that the project proposed could be successfully implemented within the actual curriculum.Keywords: PBLL, literature, gender violence, Feminist Pedagogy<br /

Laser induced surface modification for inkjet printing and coating

Lasers are nowadays widely applied in additive manufacturing and several laser based techniques related to inkjet printing are emerging. In this paper, surface treatment of nanoparticle coatings using a commercial laser engraving machine are presented. Experiments were performed on (i) thin thermally cured silver nanoparticle coatings on glass and (ii) iron oxide (Fe 2 O 3 ) nanoparticle dispersion coatings on glass. The laser treatment on Ag films illustrates local melting or dewetting behavior dependent on laser power and on the density of engraving patterns. For Fe 2 O 3 coatings, direct laser writing on dried layers and laser treatment on fluid nanoparticle ink layers are investigated. We demonstrate and discuss in particular the generation of large area laser induced microstructures in vertically confined nanoparticle ink films. Controlled ink accumulation is generated by the laser pulses. Furthermore, 2D porous network structures, as well as laser induced large area filament structures are generated by heat driven capillary flow. Tailored adjustments of nanoparticle inks, film thickness and laser treatment patterns open perspectives for the generation of laser induced self-assemblies, e.g. for novel fabrication processes for 2D metamaterials, for sensor developments or advanced anti-counterfeit applications

Is Helping Really Helping? Health-Related Quality of Life after TBI Predicting Caregiver Depression Longitudinally in Latin America

Objective: Studies have shown that functional and psychosocial sequelae of traumatic brain injury (TBI) predict emotional well-being of caregivers (Harris, 2000). Previous research examining the mental health of caregivers and the health-related quality of life (HRQoL) of people with TBI have primarily been in the US (Sander, 2012). Very little research has been conducted to uncover the unique relationships between HRQoL of people with TBI and caregiver mental health longitudinally, or in low-middle income Latin American countries. The aim of this study was to evaluate how HRQoL after TBI predict caregiver depression longitudinally in two countries and three data collection sites in Latin America. Design: Multi-site, multinational longitudinal study. Setting: Three hospitals in Neiva and Cali, Colombia, and Mexico City, Mexico (before hospital discharge), as well as in the homes of individuals with TBI and caregivers in these regions (before discharge, at 2 and 4 months after discharge). Participants: A sample of 109 TBI caregiver-patient dyads (n = 218) was included in the study. Main Outcome Measure(s): Caregiver depression (Patient Health Questionnaire-9) and HRQoL in the person with TBI (Short Form-36). Results: Three multiple regressions were conducted to examine which aspects of patient HRQoL at baseline predicted caregiver depression at baseline, 2 months, and 4 months post-discharge. Eight aspects of patient HRQoL were simultaneously entered into each model as predictors: physical functioning, role limitations (physical and emotional), vitality, mental health, social functioning, pain, and general health. At baseline, the overall model significantly predicted caregiver depression, F(8, 105) = 2.62, p = .012, R 2 = .18. Patient mental health was the only significant unique predictor of caregiver depression at baseline, p = .021, β = -.34. The overall model predicting 2-month caregiver depression was significant, F(8, 101) = 3.21, p = .003, R 2 = .22. Only mental health, p = .016, β = -.36, was a significant unique predictor. The overall model predicting 4-month caregiver depression was significant, F(8, 98) = 2.70, p = .010, R 2 = .19, and no factors uniquely predicted caregiver depression, all ps\u3e.05. Conclusions: Results suggest that TBI patient HRQoL can predict caregiver depression among Latin American caregivers before and during the first 4 months after hospital discharge. Across all three time points (baseline, 2 months, and 4 months), caregiver depression was significantly predicted by patient HRQoL. At baseline, patient mental health was the only domain that uniquely predicted caregiver depression. At 2 months, only physical role limitations uniquely predicted caregiver depression, and no unique predictors were detected at 4 months. These findings suggest that within the cultural framework in Latin America, there is a strong relationship between functional and psychological impairments after TBI and depression outcomes in Latin American caregivers. The results highlight the importance of uncovering these relational distinctions and may infer early detection of mental health needs and psychological intervention considerations for Latin American caregivers.https://scholarscompass.vcu.edu/gradposters/1052/thumbnail.jp

ABJM amplitudes and WL at finite N

We evaluate ABJM observables at two loops, for any value of the rank N of the gauge group. We compute the color subleading contributions to the four-point scattering amplitude in ABJM at two loops. Contrary to the four dimensional case, IR divergent N-subleading contributions are proportional to leading poles in the regularization parameter. We then exploit the non-planar calculation for the amplitude to derive an expression for the two-loop Sudakov form factor at any N. In the planar limit the result coincides with the one recently obtained in literature by using Feynman diagrams and unitarity. Finally, we analyze the subleading contributions to the light-like four-cusps Wilson loop and interpret the result in terms of the non-abelian exponentiation theorem. All these perturbative results satisfy the uniform transcendentality principle, hinting at its validity in ABJM beyond the planar limit.Fil: Bianchi, Marco.

South American H4N2 influenza A virus improved replication in chicken trachea after low number of passages

Introduction of influenza A viruses (FLUAV) into poultry from waterfowl is frequent, producing economic burden and increasing the probability of human infections. We have previously described the presence of FLUAV in wild birds in Argentina with unique evolutionary trajectories belonging to a South American lineage different from the North American and Eurasian lineages. Adaptability of this South American lineage FLUAV to poultry species is still poorly understood. In the present report, we evaluated the capacity of an H4N2 FLUAV from the South American lineage to adapt to chickens after low number of passages. We found that five mutations were acquired after five passages in 3-days-old chickens. These mutations produced a virus with better infectivity in ex vivo trachea explants but overall lower infection in lung explants. Infection of 3-week-old chickens persisted for a longer period and was detected in more tissues than the parental virus, suggesting adaptation of the H4N2 influenza A virus to chicken.Instituto de VirologíaFil: Ferreri, Lucas.

Predicting Caregiver Burden Over the First 4 Months After TBI in Latin America: A Multi-site, Multi-Country Study

Disparities in TBI exist between developed and developing regions, and this neurological condition typically requires caregivers to provide aid and functional support for those with TBI (Hyder, Wunderlich, Puvanachandra, Gururaj, & Kobusingye, 2007). Latin America, among these global regions, has elevated risks of both sustaining TBI and poorer post-TBI functioning (Bonow et al., 2018). Previous literature has shown the poor cognitive, mental health, and social functional outcomes following the injury (Deloche, Dellatolas, & Christensen, 2000), but research has minimally explored both longitudinal trends of these outcomes, and if functional outcomes of the injury differentially predict caregiver burden. The aim of the current study was to examine if deficits in cognitive/executive functioning, depression, and social disadaptation among individuals with TBI in Latin America predict longitudinal trajectories of caregiver burden. A sample of 109 Latin American caregivers of individuals with a newly sustained TBI, from three hospitals were included in the study. In order to evaluate this series of relationships, Hierarchal Linear Modeling (HLM) assessed whether key features of TBI (e.g, depression, cognitive dysfunction, and social disadaptation), at baseline, predicted longitudinal outcomes of caregiver burden. Study findings showed that social disadaptation significantly predicted caregiver burden trajectory. Further, results showed that caregiver burden trajectories generally decreased over time, and men reported greater caregiver burden compared to women. These findings highlight unique trends among post-TBI caregivers in Latin America and suggest that future research should assess mechanisms that influence these trends.https://scholarscompass.vcu.edu/gradposters/1090/thumbnail.jp

Precariedad laboral y trayectorias flexibles en México : un estudio comparativo de tres ocupaciones

En el contexto actual de globalización, reestructuración de los procesos productivos y flexibilización del trabajo, las investigaciones académicas coinciden en señalar que el trabajo contemporáneo se caracteriza por una condición de precariedad muy extendida. En este artículo se presentan los principales hallazgos de un estudio sobre la precariedad en México que parte de considerar la heterogeneidad del fenómeno y su fuerte carga subjetiva. Para dar cuenta de dicha diversidad y de su evolución, se comparó la situación laboral de individuos de tres ocupaciones contrastantes en diferentes regiones del país: trabajadores de la industria de la confección, trabajadores de centros de atención de llamadas y músicos profesionales. La investigación empírica estuvo sostenida por una metodología mixta que permitió la reconstrucción de los itinerarios laborales de los trabajadores a partir de la información obtenida mediante entrevistas semiestructuradas. Se concluye que la inestabilidad y la incertidumbre son predominantes excepto en segmentos de trabajadores de la industria de la confección empleados en las grandes multinacionales, en los trabajadores que hacen carrera en los centros de atención de llamadas y en los músicos con plaza en las orquestas más estables. En estas condiciones, el significado del trabajo es múltiple y exige de los individuos adaptaciones permanentes a lo largo de su vida laboral.En el context actual de globalització, reestructuració dels processos productius i flexibilització del treball, les recerques acadèmiques coincideixen a assenyalar que el treball contemporani es caracteritza per una condició de precarietat molt estesa. En aquest article es presenten les principals troballes d'un estudi sobre la precarietat a Mèxic que parteix de considerar l'heterogeneïtat del fenomen i la seva forta càrrega subjectiva. Per explicar aquesta diversitat i la seva evolució, es va comparar la situació laboral d'individus de tres ocupacions contrastants en diferents regions del país: treballadors de la indústria de la confecció, treballadors de centres d'atenció de trucades i músics professionals. La recerca empírica va ser sostinguda per una metodologia mixta que va permetre la reconstrucció dels itineraris laborals dels treballadors a partir de la informació obtinguda mitjançant entrevistes semiestructurades. Es conclou que la inestabilitat i la incertesa són predominants excepte en segments de treballadors de la indústria de la confecció col·locats a les grans multinacionals, en els treballadors que fan carrera als centres d'atenció de trucades i en els músics amb plaça en les orquestres més estables. En aquestes condicions, el significat del treball és múltiple i exigeix dels individus adaptacions permanents al llarg de la seva vida laboral.In the context of globalization, productive restructuring and labor flexibility processes, scholars agree that contemporary work features a state of extended precariousness. This article presents the main findings of research done on precariousness in Mexico, taking into account the heterogeneity as well as the subjectivity of this phenomenon. In order to show these processes, the labor situation of individuals from three contrasting occupations in different regions of the country was compared: garment industry workers, call center workers and professional musicians. The empirical inquiry was based on a mixed methodology, with information collected from semi-structured interviews used for the reconstruction of workers' labor itineraries. Overall, the study shows that instability and uncertainty are predominant features among workers of the three occupations, and only some garment workers in transnational companies, career workers in call centers and tenured musicians in large orchestras escape from precariousness. Individuals respond to this situation through permanent adaptations along their labor trajectories, and the meanings of work are multiple

Necesidad de tratamiento psicológico en personas con riesgo de cáncer hereditario que inician consejo genético. Estudio de variables predictoras

A study of Oncological Genetic Counseling (CGO) participants is realized, previously to begin the process, with the following aims: a) to provide descriptive data about cancer risk perception, Anxiety-Trait, coping competence, anxiety/depression, cancer-specific worries, previous psychological disorders, stressful life events during last 3 year, and sociodemographic and clinical characteristics, b) to determine if there are differences between 3 hereditary cancer risk syndromes: breast/ovarian, colon and others on those variables; c) to evaluate psychological intervention needs; d) to determine if those variables (risk perception, Anxiety-Trait, cancer previous, number of cancer relatives and stressful life events) can predict the need of psychological treatment. 155 participants were assessed on CGO Unit at Hospital Cl?nico San Carlos with hereditary risk of cancer (breast/ovarian: 77; colon: 53; others: 35). The sample characteristics were: 76.8% women, age mean: 44 years, 70% were married with children, and hight educational level (40% universitary studies). There were 37% with previous cancer diagnostic. Risk perception was moderately high: there were 34% that considered his/her risk higher than 50% and 20% considered that risk was higher than 75%. Most participants considered themselves with good ability to cope with cancer risk (91%), but 40% report anxiety/depression and worries cancer-specific. 65% has suffered stressful live events in the last 3 years. 28% have received psychological treatment in the last two years. The scores on Anxiety-Trait (STAI-R) were on normal range for Spanish population. MANOVA gender x hereditary syndromes (breast/ovarian, colon and others) showed higher scores of colorectal cancer participants on STAI-R (p=0.009); Moreover, women with previous cancer have a higher score on STAI-R than women without previous cancer diagnostic. There were 33 (25%) of 133 participants assessed that need psychological attention. AMOS 5 regression model with observed variables: STAI-R, previous cancer diagnostic, risk perception, number of cancer relatives, and stressful life events, explained 51% of the variance of psychological treatment needs. The analysis of ROC Curve using as contrast STAI-T variable to classify participants as positive or negative for need of psychological treatment showed that the STAI-R is a useful screening tool for psychological treatment needs. It is concluded that psychological intervention is necessary for a significative number of CGO participants

Maloclusión y necesidad de tratamiento ortodóncico según dos métodos cuantitativos

Las maloclusiones se encuentran entre las alteraciones orales de mayor prevalencia e impacto en el mundo y requieren de un diagnóstico preciso al momento de definir la necesidad de tratamiento ortodóncico en los pacientes. Para ello se recurre, al uso de métodos cuantitativos como lo son los índices oclusales. Entre ellos, los más utilizados mundialmente se encuentran el Índice Estético Dental y el Índice de Necesidad de Tratamiento Ortodóncico. El objetivo del trabajo es determinar la prevalencia de maloclusión y necesidad de tratamiento ortodóncico en niños con dentición mixta, según dos métodos cuantitativos, el Índice Estético Dental (DAI) y el Índice de Necesidad de Tratamiento Ortodóncico (IOTN). Se realizó un estudio descriptivo observacional, de corte transversal, en el que seleccionaron 20 pacientes que concurrieron al Módulo de Atención Integral del niño y adolescente de la Facultad de Odontología de la UNNE, para su atención integral. A todos los pacientes seleccionados que se ajustaron a los criterios de inclusión/exclusión, se les aplicó dos índices cuantitativos, el Índice Estético Dental (DAI) y el Índice de Necesidad de Tratamiento Ortodóncico (IOTN). Hasta el momento, se pudo determinar una alta prevalencia de maloclusión discapacitante en el 35% según el DAI con una necesidad de tratamiento ortodóncico obligatorio y grado 2 maloclusión leve en el 25% según el Índice de Necesidad de Tratamiento (IOTN) en niños con dentición mixta del Módulo Atención Integral del niño y adolescente de la Facultad de Odontología de la UNNEFil: Olivera, Paola B.
