Multimodality for comprehensive communication in the classroom: Questions in guest lectures

In recent years there have been many studies about the discourse of lectures (Pérez-Llantada & Ferguson, 2006; Csomay, 2007; Deroey & Taverniers, 2011). Lecturing is the most common speech event in most university classrooms in the world. Bamford (2005) defines lectures’ styles as conversational, stressing the interactive nature of the lecture, the main goal of which is to establish contact with the students, and the co-option of the students into a discourse community. However, most of the studies published up to this moment have focused exclusively on the language used by the lecturer and little attention has been paid to the role of multimodality in this particular genre. In our research, we try to identify the non-verbal behaviour that can be of special relevance for the comprehensive communication in the classroom, focusing on questions in two guest lectures in English delivered for a group of Spanish students. Results indicate that both lecturers use different verbal and non-verbal strategies to foster interaction, adapting to the characteristics of their audience. The final objective of this study is twofold: i) to use the results in our courses for training Spanish lecturers on teaching in English; and ii) to use these results for EAP undergraduate courses, as it has been observed that body language needs awareness raising in order to facilitate transfer from mother tongue to another language

Determination of priority conservation areas in the Puna and Prepuna of northern Argentina

Actualmente existe una gran preocupación debido a la pérdida de la biodiversidad como resultado de la destrucción y modificación de los hábitats naturales causada por las actividades del hombre. Una de las soluciones más comunes a este problema es el establecimiento de redes de áreas protegidas, con el objetivo de conservar la mayor cantidad y diversidad de hábitats posibles. El objetivo de este trabajo fue realizar una determinación de áreas de endemismo y riqueza específica para 16 especies de peces, 11 especies de anfibios, 24 especies de reptiles y 46 especies de plantas en la región de Puna y Prepuna del Noroeste Argentino. Se identificaron áreas de endemismo utilizando el criterio de endemicidad implementado en el programa NDM, y para la estimación de riqueza se utilizó el programa DIVA-GIS. Las áreas identificadas mediante los dos análisis son congruentes entre sí, resultando en 5 áreas, donde 4 de ellas coinciden con áreas que ya poseen políticas de conservación, mientras que 1 no coincide con ninguna reserva, por lo que a futuro podría ser considerada en nuevos planes de conservación. Este enfoque constituye un aporte novedoso para abordar una planificación sistemática de Áreas Prioritarias que junto a otros aportes filogenéticos, geográficos, ecológicos conformen una herramienta eficaz y útil, para los organismos encargados de la toma de decisiones en políticas de conservación.There exists a great concern about the loss of biodiversity as a result of destruction and modification of natural habitats caused by human activities. One of the most common solutions to this problem is to establish protected area networks to conserve as many habitats as possible. The objective of this work was to determine areas of endemism and specific richness for 16 species of fish, 11 of amphibians, 24 of reptiles, and 46 species of plants in the Puna and Prepuna region of Northwestern Argentina. Areas of endemism were identified using the endemicity criterion implemented in the software NDM, and DIVA-GIS was used for richness estimation. Five congruent areas were identified by the two analyses, four of them coincide with areas that already have conservation policies, while one does not coincide with any protected area. In the future this area could be considered in new conservation programs. This approach constitutes a novel contribution to a systematic planning of Priority Areas, which together with other contributions (ecological, geographic, and phylogenetic) constitute an effective and useful tool for decision-making agencies in conservation policies.Fil: Portelli, Sabrina Noelia.

Parasite detection in chronically ill patients is restricted to serological tests that only determine infection by previous infection and not the presence of the parasite, especially in patients undergoing treatment evaluation or in newborns. We have evaluated the use of nucleic acids from both circulating exovesicles and cell-free DNA (cfDNA) from 50 samples twice randomly selected from a total of 448 serum samples from immunologically diagnosed patients in whom the presence of the parasite was confirmed by nested PCR on amplicons resulting from amplification with kinetoplastid DNA-specific primers 121F-122R. Six samples were randomly selected to quantify the limit of detection by qPCR in serum exovesicles. When the nucleic acids thus purified were assayed as a template and amplified with kinetoplastid DNA and nuclear satellite DNA primers, a 100% positivity rate was obtained for all positive samples assayed with kDNA-specific primers and 96% when SAT primers were used. However, isolation of cfDNA for Trypanosoma cruzi and amplification with SAT also showed 100% positivity. The results demonstrate that serum exovesicles contain DNA of mitochondrial and nuclear origin, which can be considered a mixed population of exovesicles of parasitic origin. The results obtained with serum samples prove that both cfDNA and Exovesicle DNA can be used to confirm parasitaemia in chronically ill patients or in samples where it is necessary to demonstrate the active presence of the parasite. The results confirm for the first time the existence of exovesicles of mitochondrial origin of the parasite in the serum of those affected by Chagas disease.ERANet17/HLH-0142Instituto Carlos III, Ministerio de Sanidad, Gobierno de EspañaFundación Ramón ArecesSpanish Government PGC2018-099424-B-I00I+D+i Proyect "Programa Operativo FEDER de Andalucia JJAA" A-BIO-350-UGR1

Anesthesia for Echocardiography and Magnetic Resonance Imaging in the African Clawed Frog (Xenopus laevis)

This report describes an anesthesia technique that we used to study cardiovascular anatomy and physiology with echocardiography and cardiac magnetic resonance (CMR) in 46 African clawed frogs (Xenopus laevis) (n = 24 for electrocardiography and n = 22 for CMR). For administration of anesthesia, 3 holding tanks, one each for transportation, sedation, and recovery, were filled with filtered water, with 0.05% buffered tricaine methasulfonate solution (MS-222) added into the sedation tank. Fifteen minutes after the frog was placed in the sedation tank, a paper towel was soaked in MS-222 solution, and the frog was placed in a supine position and rolled 3 to 4 times in the soaked paper with the head and legs exposed. Vital signs were monitored and recorded throughout the procedure. After imagining, frogs were unrolled from the paper towel, placed in the recovery tank, and later returned to their home tank. Monitoring was discontinued when the frogs resumed typical activity. No mortality or complications were observed in frogs that underwent this procedure. Mean duration ± 1 SD of anesthesia induction was 12 ± 5 min in the echocardiography group and 14 ± 6 min in the CMR group. The mean duration of anesthesia maintenance was 60 ± 18 min in the echocardiography group and 118 ± 37 min in the CMR group. An additional dose of anesthesia was necessary during maintenance for 9 of 24 (37%) frogs in the echocardiography group and 6 of 22 (27%) frogs in the CMR group. At the end of the procedure, the mean oxygen saturation was 66 ± 9% in the echocardiography group and 85 ± 6% in the CMR group, and heart rate was 48 ± 13 beats/min in the echocardiography group and 42 ± 7 beats/min in the CMR group. We conclude that the anesthesia technique of immersion in MS-222 is suitable for performing echocardiography and CMR imaging in this species without complications

Reproducibility and clinical relevance of the ocular response analyzer in nonoperated eyes: corneal biomechanical and tonometric implications

To assess the reproducibility of the ocular response analyzer (ORA) in nonoperated eyes and the impact of corneal biomechanical properties on intraocular pressure (IOP) measurements in normal and glaucomatous eyes. METHODS: In the reliability study, two independent examiners obtained repeated ORA measurements in 30 eyes. In the clinical study, the examiners analyzed ORA and IOP-Goldmann values from 220 normal and 42 glaucomatous eyes. In both studies, Goldmann-correlated IOP measurement (IOP-ORAg), corneal-compensated IOP (IOP-ORAc), corneal hysteresis (CH), and corneal resistance factor (CRF) were evaluated. IOP differences of 3 mm Hg or greater between the IOP-ORAc and IOP-ORAg were considered outcome significant. RESULTS: Intraexaminer intraclass correlation coefficients and interexaminer concordance correlation coefficients ranged from 0.78 to 0.93 and from 0.81 to 0.93, respectively, for all parameters. CH reproducibility was highest, and the IOP-ORAg readings were lowest. The median IOP was 16 mm Hg with the Goldmann tonometer, 14.5 mm Hg with IOP-ORAg (P < 0.001), and 15.7 mm Hg with IOP-ORAc (P < 0.001). Outcome-significant results were found in 77 eyes (29.38%). The IOP-ORAc, CH, and CRF were correlated with age (r = 0.22, P = 0.001; r = -0.23, P = 0.001; r = -0.14, P = 0.02, respectively), but not the IOP-ORAg or IOP-Goldmann. CONCLUSIONS: The ORA provides reproducible corneal biomechanical and IOP measurements in nonoperated eyes. Considering the effect of ORA, corneal biomechanical metrics produces an outcome-significant IOP adjustment in at least one quarter of glaucomatous and normal eyes undergoing noncontact tonometry. Corneal viscoelasticity (CH) and resistance (CRF) appear to decrease minimally with increasing age in healthy adults

Development and Validation of a Questionnaire of the Perioperative Nursing Competencies in Patient Safety

Delphi method; Competencies; Psychometric propertiesMètode Delphi; Competències; Propietats psicomètriquesMétodo Delphi; Competencias; Propiedades psicométricas(1) Background: This research presents the CUCEQS© (Spanish acronym for Questionnaire of Perioperative Nursing Safety Competencies), which evaluates the perception of perioperative nurses about their competencies related to surgical patient safety. The aim of the present study was to design, validate, and analyze the psychometric properties of the CUCEQS©. (2) Methods: We devised an instrumental, quantitative, and descriptive study divided into two phases: in the first, the questionnaire was designed through a Delphi method developed by perioperative nurses and experts in patient safety. In the second, the reliability, validity, and internal structure of the tool were evaluated. (3) Results: In the first phase, the items kept were those that obtained a mean equal to or higher than four out of five in the expert consensus, and a Content Validity Index higher than 0.78. In the second phase, at the global level, a Stratified Cronbach’s Alpha of 0.992 was obtained, and for each competency, Cronbach’s Alpha values between 0.81 and 0.97 were found. A first-order confirmatory factor analysis of the 17 subscales (RMSEA 0.028, (IC 90% = 0.026–0.029) and its observed measures was performed for the 164 items, as well as a second-order analysis of the four competencies (RMSEA = 0.034, (IC90% = 0.033–0.035). (4) Conclusions: The questionnaire is a valid tool for measuring the perceived level of competency by the perioperative nurses in surgical patient safety. This is the first questionnaire developed for this purpose, and the results obtained will facilitate the identification of areas to be improved by health professionals in patient safet

De esta manera se aseguró la calidad e inocuidad del producto

Conectividad entre las subpoblaciones de rata noruega (Rattus norvegicus) que habitan granjas avícolas de Exaltación de la Cruz, Buenos Aires, Argentina

Despite of the substantial economic and human health problems produced by rodents of the genus Rattus almost nothing is known about its actual dispersal. In the present study we analyze the genetic subdivision of R. norvegicus inhabiting poultry farms of Buenos Aires, Argentina, and the relation between geographic and genetic distances by means of variation in microsatellite loci. We genotyped 40 rats captured between April-06 and June-07 from nine poultry farms distributed in an area of 110 km2 . No genetic subdivision was found among di erent poultry farms. This result supports the hypothesis of high connectivity between R. norvegicus inhabiting poultry farms in Buenos Aires. Because this species is a known host of diverse zoonosis as leptospirosis and trichinosis, our results point out that there is a great risk of transmission for distances lower than 12 km. Health control and preventive measures should therefore be applied simultaneously in all nearby poultry farms.A pesar de los problemas económicos y de salud producidos por roedores del género Rattus, se conoce muy poco sobre su dispersión efectiva. En el presente estudio analizamos la subdivisión genética de las subpoblaciones de R. norvegicus que habitan granjas avícolas de Buenos Aires, Argentina, y la relación entre las distancias geográ cas y genéticas por medio de la variabilidad en loci de microsatélites. Se genotiparon 40 ratas capturadas entre abril-06 y junio-07 en nueve granjas avícolas distribuidas dentro de un área de 110 km2 . No se encontró subdivisión genética entre las diferentes granjas avícolas. Esto apoya la hipótesis de alta conectividad entre R. norvegicus que habitan granjas avícolas en Buenos Aires. Debido a que R. norvegicus es un conocido hospedador de diversas zoonosis como leptospirosis y triquinosis, nuestros resultados indican que existe un gran riesgo de transmisión para distancias menores a 12 km. La medidas de control y prevención sanitarias deberían, por lo tanto, aplicarse en todas las granjas cercanas en forma simultánea.Fil: Gomez Villafañe, Isabel Elisa.
