Este estudio examina la viabilidad e impacto de adaptar el modelo de intervención multinivel de Respuesta a la Intervención (RTI) al contexto de las aulas argentinas, enfocándose específicamente en la mejora de la lectura en estudiantes de tercer grado a partir de la capacitación a docentes. El modelo RTI tradicional, que generalmente presenta intervenciones escalonadas en el tiempo, fue reestructurado juntando la propuesta de tier1 y tier2, para permitir que los docentes planifiquen y ejecuten secuencias de instrucción de tres niveles simultáneamente dentro del mismo ambiente del aula. Esta adaptación tuvo como objetivo abordar la trayectoria de aprendizaje única de cada estudiante proporcionando andamiaje a medida. La investigación se llevó a cabo con 164 estudiantes de tercer grado de dos escuelas privadas en la Provincia de Santa Fe, Argentina. Se empleó un diseño cuasi-experimental para evaluar el impacto de la intervención en las habilidades de lectura. Los docentes fueron capacitados en prácticas de lectura y escritura basadas en la evidencia, así como en el modelo RTI adaptado, que proponía enseñanza explícita a todo el grupo y luego el trabajo en pequeños grupos por niveles dentro del aula, bajo la guía del mismo maestro. La efectividad de la intervención se evaluó mediante la herramienta de evaluación digital "Screening del Nivel Lector" en tres momentos: al inicio de la intervención, después de su aplicación y seis meses más tarde sin intervención adicional. Los hallazgos iniciales revelaron que los estudiantes del grupo de intervención, en comparación con un grupo de control, mostraron una mejora significativa en el rendimiento lector inmediatamente después de la intervención. Este progreso se mantuvo en el tiempo, con una disminución en el número de estudiantes en riesgo de dificultades de lectura. El estudio respalda la efectividad de la instrucción explícita y el trabajo en pequeños grupos para mejorar la competencia lectora. Además, el modelo RTI adaptado demuestra ser un enfoque prometedor para entornos educativos con recursos limitados donde el apoyo docente adicional es escaso.

As a result of the COVID-19 pandemic situation, the psychoeducational work was forced to carry out virtual interventions. In this work, progress in reading skills was compared in face-to-face vs. virtual intervention in patients with dyslexia. The evolution of 26 patients from 1st to 3rd grade exposed in both formats to the same reading intervention with a cognitive program, was analyzed. The results showed that both in the virtual and face-to-face modalities, an improvement was achieved in phonological skills, reading fluency and decoding, with no significant difference across modalities. In conclusion, virtual interventions can be effective if an explicit and systematic treatment is carried out, with an evidencebased program and based on an initial faceto-face bond.

Ginger, galangal, and turmeric (Figure 1) are emerging crops for Florida production. All of these plants are in the Zingiberaceae family and share most aspects of their production. This bulletin describes production in containers or the field under Florida conditions to help guide growers interested in ginger, turmeric, and galangal production or expanding their market. All species have been evaluated by the UF/IFAS Assessment of Non-native Plants in Florida’s Natural Areas (UF/IFAS Assessment) using the Predictive Tool (an invasion risk assessment) and all present a low risk of invasion in Florida (https://assessment.ifas.ufl.edu).

Abstract Aniara sepulchralis specimens sampled at different locations (Belém and Bragantina microregions) show differences in size of some morphological structures such as head width, pronotum width, distance between eyes, pronotum base width, labral length, labral width, and spur of the third pair of legs. These changes may be due to biotic, abiotic, and structural factors peculiar to each environment. Differences in structures and morphological measurements of males and females of Aniara sepulchralis were observed, characterized as sexual dimorphism in relation to their teeth and labral-clypeal suture. Females present apical teeth and rectilinear suture, whereas males present a more rounded shape in both teeth and the labral-clypeal suture. Regarding measurements, females have greater body length, head width, eye distance, pronotum length, pronotum width, labral length, and pronotum base width than males.

A better understanding of the contribution of the socioeconomic status (SES) in sleep health could guide the development of population-based interventions aiming to reduce “the silent public health issue” that are sleep disturbances. PRISMA was employed to identify relevant studies having examined the association between social class, social capital, education, income/assets, occupation/employment status, neighborhood deprivation and sleep health. Sixteen cross-sectional and three longitudinal studies were selected, having sampled 226,029 participants aged from 2 months to 85 years old. Findings showed that: (1) sleep health disparities among children and adolescent are strongly correlated to parental socioeconomic indicators; (2) poor parental income, poor family SES and poor parental education are associated with higher sleep disturbances among children and adolescents; (3) lower education is a predictor of increased sleep disturbances for adults; (4) low SES is associated with high sleep disturbances in adults and old people and; (5) low income and full-time employment was significantly associated with short sleep among adults and old people. In conclusion, sleep health should be an important public health target. Such intervention would be beneficial for populational health, for all taxpayers and public administrations, which would see a reduction in absenteeism and productivity losses attributable to sleep-related health problems in the global economy.

Foi realizado um levantamento bibliográfico a respeito do atual questionamento sobre possíveis intercorrências pelo novo coronavírus (COVID-19) em espécies animais e a possibilidade da transmissão direta entre animais infectados e seres humanos. Uma revisão bibliográfica em livros, periódicos, artigos científicos, revistas eletrônicas e páginas oficiais de organizações internacionais e órgãos públicos que foram julgados pertinentes ao tema. Foi realizado com base em dados publicados Pubmed, Scielo e Google acadêmico. O estudo foi direcionado entre os casos relatados em canídeos e felinos até o dia 17 de abril de 2020. As pesquisas em andamento e as já finalizadas demonstram que o COVID-19 nas espécies domésticas manifesta-se como uma zoonose reversa, sendo gatos e furões as espécies mais propensas de contrair o vírus em relação a cães. Por meio dessa revisão bibliográfica concluiu-se que gatos e furões caso desenvolvam a doença, é de considerável menor gravidade e mortalidade ao se comparar com os casos clínicos em humanos. Já os cães parecem ter baixíssimos índices de contratilidade do vírus e não aparentam correr risco de saúde diante da atual pandemia.

This essay examines the way in which two late twentieth-century Latin American novelists address movement through the city of Paris. Building on existing work by Julie Jones (1998), Jason Weiss (2003), Axel Gasquet (2007) and especially Marcy E. Schwartz (1999), this project moves beyond a genealogy of Latin American writers in Paris towards a conception of the relationship between narrative form and depictions of urban navigation. It proposes that Julio Cortázar in Rayuela (1963) and Luisa Futoransky in De Pe a Pa (1986) enact a mode of movement through the discontinuous and episodic forms of their novels, and that the contrast between their depictions of movement, and particularly their depictions of the relationship between fragmentation and continuity within this movement, can be most clearly understood along the axis of gender. That is, while for Oliveira in Rayuela movement through the city is largely uninterrupted and can preserve at least an illusion of fluidity, for Laura in De Pe a Pa the woman’s movement through Paris is always discontinuous, difficult and even dangerous. Futoransky revises that earlier male writer’s formulation of movement to draw attention to a masculine complacency which organises Rayuela and to propose a new model for female urban navigation.

RESUMEN Se presenta un consenso latinoamericano que permite estandarizar las definiciones de los diferentes niveles de resistencia a los antimicrobianos en bacterias de importancia en salud pública. Se describen los criterios de inclusión y exclusión para las metodologías a utilizar y para los antibióticos a incluir (por disponibilidad, relevancia y existencia de puntos de corte). Como propuesta piloto se eligieron tres microorganismos gramnegativos de gran impacto en el ambiente hospitalario (Klebsiella pneumoniae, Pseudomonas aeruginosa y Acinetobacter spp.). La falta de puntos de corte para ciertos antibióticos (por ejemplo, tigeciclina, fosfomicina y colistina), claves para el tratamiento de infecciones causadas por estos patógenos que presentan multirresistencia o resistencia extendida, llevó a la necesidad de discutir y consensuar puntos de corte provisorios para la vigilancia de la resistencia a estos fármacos. Se abordó y consensuó también el uso de pruebas de sensibilidad alternativas a los métodos aprobados por las guías internacionales, de aplicación más sencilla como pruebas de rutina en los laboratorios de bacteriología clínica. El principal beneficio de este documento es proporcionar a los laboratorios latinoamericanos un marco estandarizado y consensuado para la identificación y la vigilancia constante y unificada de microorganismos resistentes. Las recomendaciones incluidas en este documento son el resultado consensuado por los representantes de los laboratorios nacionales de referencia de los países que integran la Red Latinoamericana de Vigilancia de la Resistencia a los Antibióticos coordinada por la Organización Panamericana de la Salud.

Propagation of hops has traditionally been accomplished through vegetative techniques. A more modern technique, micropropagation, can be used to propagate hops and offers several advantages to vegetative techniques. Research examining the use of LED lights in plant production has observed its ability to promote growth in plants through emission of higher light quality, such as enhanced red and blue wavelength discharge. This new 5-page EDIS publication provides information on the use and application of LED lights to enhance leaf area and root length of hops. Written by Chi D. Nguyen, Dominic Vu, Heqiang Huo, and Brian Pearson, and published by the UF/IFAS Environmental Horticulture Department. https://edis.ifas.ufl.edu/ep583

Hops (Humulus lupulus) are perennial plants commonly harvested for their mature strobiles, also referred to as cones, which are primarily dried and used as a bittering agent and preservative in beer production. The two primary factors of harvest timing and harvest method can have large impacts on the quality and economics of the finished product. The decision of when and how to harvest is important and should rely upon growing-region-specific environmental conditions, physical observations of the cones, and the wants and needs of the individual producer. This new 4-page publication of the UF/IFAS Environmental Horticulture Department describes the primary methods used in hop harvesting, including field, indoor, and machine harvesting.

Butterfly pea (Clitoria ternatea), a twining vine native to Southeast Asia, produces deep blue to purple flowers that bloom nearly year-round in ideal conditions. When extracted in a liquid, the addition of a mild acid such as lemon or lime juice turns the naturally deep blue to purple color into a much lighter pink or purple color, giving the extract its color-changing ability. This new 5-page publication of the UF/IFAS Environmental Horticulture Department outlines the use of butterfly pea flower extract (BPFE) as a pH-dependent natural colorant, including an explanation of the science behind the color change, detailed parameters for flower extraction, instructions for storage and processing of the extract as well as a discussion of some of the other benefits of using BPFE. http://edis.ifas.ufl.edu/ep573

Fresh horticultural goods often require drying post-harvest to preserve quality and allow for successful long-term storage of plant material.

Pregnancy loss is an important aspect of equine practice due to the economic and emotional loss that it engenders. Pregnancy loss is often divided in two categories: early pregnancy loss (EPL) or embryonic death (ED) (first 42 days) and fetal losses (after 42 days). Diagnosis of the causes of pregnancy loss is often very challenging. Many of the causes of EPL remain poorly documented but studies on embryo development and embryo-uterine interaction have been able to shed some light on predisposing factors. Fetal losses or abortions are dominated by infectious causes and particularly bacterial placentitis. Detailed reviews of pregnancy loss were recently published by the authors (Tibary et al., 2012; Tibary and Pearson, 2012; Tibary et al., 2014). The objective of this paper is to provide an overview of the epidemiology, etiology, diagnosis and prevention of pregnancy loss in the mare.

Would you know what to do if you saw a two-foot-tall, 100-pound exotic rodent strolling through your neighborhood? It’s highly unlikely, but, depending on your location, not absolutely impossible. Capybaras, the world’s largest rodents, are native to South America but have been spotted in the state of Florida and may have potential to establish populations here. This 5-page fact sheet written by Brandon Parker, C. Jane Anderson, Christina Romagosa, Samantha Wisely, Daniel Pearson, John Seyjagat, and Katherine Ashley Sayler and published by the UF/IFAS Department of Wildlife Ecology and Conservation describes capybaras, explains how they got to Florida, and shows where the semiaquatic, herbivorous rodents have been sighted so far. edis.ifas.ufl.edu/uw438

En Limón Reggae, la autora describe las experiencias de una protagonista que no tiene entrada en ningún grupo: nación, raza o grupo político. Son representaciones de las comunidades afrocaribeñas junto con la lucha revolucionaria en El Salvador y las experiencias de los niños de la calle. En After Exile, Amy Kaminsky plantea la presencia de imágenes corporales en la obra de muchos escritores latinoamericanos exiliados o expatriados. Rossi explora situaciones desesperadas centroamericanas y mundiales, junto a una lucha de resistencia. In Limón Reggae, the author describes the experiences of a protagonist who never finds acceptance or inclusion in any group, whether that of nation, ethnicity or politics. We find representations of Afro-Caribbean communities along with the revolutionary struggle in El Salvador and the experiences of present-day street children. In After Exile, Amy Kaminsky acknowledges the presence of images of the body in the work of many Latin American writers who have been exiled or have lived expatriate lives. Rossi explores desperate situations, both Central American and worldwide, together with a resistance struggle.

¿Cuál es el aporte fundamental que puede hacer la universidad pública para el desarrollo y fortalecimiento de una economía social y solidaria y cuáles son las principales limitaciones, desafíos y potencialidades que encontramos día a día en el proceso de construcción de otra economía? El presente artículo tiene por horizonte compartir y exponer de forma ordenada algunas de las reflexiones y debates vinculados al desarrollo de la economía social y solidaria durante los últimos años en Argentina, poniendo especial atención a su presencia en el ámbito de las universidades públicas y de la articulación de éstas con las políticas públicas destinadas a su promoción. Para exponer estas reflexiones y análisis se hará pie en la experiencia real y concreta que estamos desarrollando desde el año 2011 en el marco del Programa de Economía Social y Solidaria (Programa ESS) de la Secretaría de Extensión de la Universidad Nacional del Centro de la Provincia de Buenos Aires.

Public schools in some areas of the U.S. are as segregated as they were prior to court-ordered busing, in part due to school choice policies that appear to exacerbate extant segregation. In particular, Latina/o students are increasingly isolated in schools characterized as being in cycles of decline. Our case study of one such school is based on a reanalysis of interview, focus group, and survey data from three research and evaluation projects. We constructed accounts of parents’ decisions to leave and remain at Martinez Elementary, a segregated dual language school experiencing increases in Latina/o and low socio-economic student enrollment and decreasing statewide standardized test scores. Interpreting Latina/o and White parents’ accounts through LatCrit theory, we sought to understand their choices to attend this school as counterstories that illustrate conflicting forces influencing Martinez, including high parent satisfaction and interest convergence between White and Latina/o parents. These stories depict a more hopeful account of a school resisting decline, yet only the adoption of managed school choice policies may be powerful enough to counter the school’s segregation.

Al momento de contacto con los europeos, existían dos grupos humanos que ocupaban Tierra del Fuego, presentando diferentes estrategias de subsistencia: los yámana a lo largo de las costas oeste y sur de la isla, y los selk’nam en el interior. Estas poblaciones, que soportaron uno de los climas más fríos de Sudamérica, representan una valiosa oportunidad para estudiar tanto sus adaptaciones a largo plazo al clima, como aquéllas a corto plazo relativas a sus actividades habituales. Estos distintos patrones de subsistencia permiten predecir diferentes robusteces y morfología de las diáfisis en los huesos largos de extremidades superiores e inferiores. Debido al clima, los niveles de robustez de extremidades y articulaciones, así como sus proporciones corporales, deberían ser similares a aquellos grupos humanos adaptados al frío. Existen escasos restos esqueletales de miembros de estos grupos en Norte América y Europa. La muestra analizada corresponde a 14 esqueletos selk’nam y 6 yámana, pertenecientes a museos de Argentina y Chile, la que fue incrementada con datos relevados de publicaciones. Se calcularon y compararon los índices de robustez de las diáfisis y epífisis de los huesos largos, el ancho relativo bi-iliaco y la proporción AP/ML medial de las diáfisis. Los resultados obtenidos muestran que los fueguinos presentan huesos largos extremadamente robustos y pelvis relativamente anchas, similares a la mayor parte de las poblaciones recientes adaptadas al frío. Sin embargo, cuando los conjuntos se estratificaron por sexo, no se encontraron diferencias significativas entre las extremidades superiores e inferiores, ni tampoco entre los índices pilástrico y platicnémico. Debe por tanto tenerse cuidado en la interpretación de dichos rasgos, toda vez que la literatura etnográfica señala diferencias entre las actividades de ambos grupos, pero sus esqueletos no las manifiestanThe people who lived on Tierra del Fuego Island at the time of European contact offer a remarkable opportunity to study the effects on the skeleton of long-term adaptation to climate and the short-term adaptation to habitual activity. The island provided one of the coldest habitats in South America. Two groups with different subsistence strategies occupied the island at contact: the Yámana along the southern and western coast and the Selk’nam in the interior. The dissimilar subsistence patterns would support contrasting predictions about robusticity and diaphyseal shapes of long bones in the upper and lower limb. Due to climate, both groups should show levels of limb and joint robusticity and body proportions similar to other cold adapted humans. Skeletons of either group are rare in North America and Europe. Selk’nam and Yámana skeletons were measured at Museums in Argentina and Chile and supplemented with published data. Robusticity indices of the shafts and epiphyses of limb bones, relative bi-iliac breadth, and AP/ML midshaft ratios were calculated and compared. The results show the Fueguians had very robust limb bones and relatively broad pelves in common with the most cold-adapted recent populations. However, no significant differences existed in matched-sex comparisons of upper limb versus lower limb robusticity or in pilastric and platycnemic indices. The difference in ethnographically documented activity and lack of its skeletal manifestation argues for the use of caution in interpreting these traits

Hops are perennial, herbaceous climbing plants commonly cultivated for their strobiles or cones (Figure 1). The cones are often used for flavoring and aroma in food, tea, and beer (Burgess 1964). Hops can make a unique addition to a home garden or landscape. It grows rapidly in the early spring to late summer. Plants reach a mature height of 18–25 feet in one year and produce cones from mid-summer to early fall. This 2-page fact sheet was written by Brian J.

Newly constructed urban residential landscape soils sampled within Central Florida are dominated by large sand particles and possess low soil moisture retention. Therefore, irrigation and fertilizer applications should be managed to match site conditions and prevent overapplication of water and nutrient leaching. Sampled soils in newly developed urban residential communities were found to be highly compacted and likely to inhibit plant establishment and growth. This 3-page fact sheet was written by Brian J. Pearson, and published by the UF Department of Environmental Horticulture, September 2013. http://edis.ifas.ufl.edu/ep479

Ruminants are the main reservoir of Coxiella burnetii, an obligate intracellular Gram negative pathogen. This microorganism is the causative agent of Q fever, a a zoonosis transmited to humans by contacting contaminated fluids from infected animals, inhaled aerosols or consuming milk from infected animals. We used Real-Time PCR assay with a Taq-Man fluorescent probe to detect the pathogen in samples of bovine milk collected from random locations in nine Ecuadorian provinces. The assay targeted a 61-63bp repetitive sequence within the IS1111 transposon in C. burnetii. The assay found positive samples in two provinces located close to the Colombian and Peruvian borders and in Chimborazo (Ecuadorian central region). This study is the first in Ecuador to detect Coxiella burnetii using a molecular method of high sensitivity.

Desde mediados del siglo XX Enfermería ha desarrollado un cuerpo de conocimientos propio que la ha situado, como una disciplina más, en el espacio general de la Ciencia. Los avances científico-técnicos y las transformaciones sociales del mundo contemporáneo han condicionado cambios importantes en los estilos de vida y nuevos requerimientos en relación a los procesos de salud, enfermedad y atención sanitaria. La Enfermería, la ciencia del cuidado de la vida, no ha quedado al margen de estos cambios y demandas. El desarrollo de teorías y modelos de enfermería durante este periodo ha condicionado transformaciones importantes en la profesión enfermera en todos los contextos mundiales. La evolución de la enfermería en España en los últimos 50 años ha sido el reflejo de estos desarrollos teóricos y metodológicos de la disciplina a nivel internacional, y de los procesos socioculturales, políticos y educativos específicos de la enfermería en el contexto nacional español. En este trabajo se pretende identificar los cambios en el pensamiento enfermero y en las prácticas y roles de la enfermería, a través de las narraciones de tres enfermeras que han ejercido su actividad asistencial en el ámbito hospitalario de la ciudad de Castellón (España) en diferentes periodos de la historia reciente. Para realizar este estudio cualitativo se han recogido los relatos de vida profesional de tres enfermeras hospitalarias de distintas generaciones para, a través sus voces, realizar un análisis comparativo de sus vivencias y percepciones que nos permita detectar cómo ha evolucionado y se ha transformado la enfermería en España en los últimos 50 años, y cómo el devenir sociohistórico de la profesión ha incidido en sus actores/as.
