Meaning-making from wordless (or nearly wordless) picturebooks: what educational research expects and what readers have to say

Wordless (or nearly wordless) picturebooks are intriguing in terms of how readers make meaning from them. This article offers a conceptualization of existing studies in the field of education that use wordless picturebooks with young readers. While some of these studies contribute to understanding meaning-making, the pragmatic use of wordless picturebooks often does not take account of their particular nature and of the heightened role of the reader, leading to a mismatch between what the picturebook expects from the implied reader and the researchers’ expectations of what ‘real’ readers must do with these books. By highlighting observations from children’s literature scholarship and reader-response studies, this article aims to encourage a more interdisciplinary understanding of meaning-making. It also seeks to persuade educational researchers and mediators to consider investigative approaches that are not based on verbalization but are more in tune with the invitations that wordless picturebooks extend to young readers

Effect of the temperature and relative humidity in stored sotol (Dasylirion cedrosanum Trel.) seeds on fungi biodiversity

The objective of the research was to identify the fungi in sotol seeds at different conditions of temperature and relative humidity. Seeds were collected at Buñuelos, municipality, and taken to the Laboratory of the Center for Training and Development in Seed Technology (CCDTS) at Universidad Autonoma Agraria Antonio Narro. The seed was stored for a period of 90 days, whit conditions of 60, 75, 80 and 85% of relative humidity kept at 5, 15 and 25 °C. Fungi identifying by morphological criteria. A completely randomized experiment using R software, with factorial arrangement whit two replications. Pathogens identified were: Aspergillus glaucus, Aspergillus niger, Fusarium sp., Penicillium sp., Aspergillus candidus, Cladosporiun sp., Alternaria sp. and Aspergillus chraceus, the results showed that the higher the humidity, temperature and storage time, the incidence of fungi tends to be higher. Fungi with a higher presence in sotol seeds were: Aspergillus glaucus and Penicillium sp. Safe storage environments for sotol seeds reported in this work are 5 °C and a relative humidity of 60-75%. Sotol seeds tolerates conditions of 15 °C and a relative humidity up to 75%.&nbsp

Photoluminescence Stokes shift and exciton fine structure in CdTe nanocrystals

The photoluminescence spectra of spherical CdTe nanocrystals with zincblende structure are studied by size-selective spectroscopic techniques. We observe a resonant Stokes shift of 15 meV when the excitation laser energy is tuned to the red side of the absorption band at 2.236 eV. The experimental data are analyzed within a symmetry-based tight-binding theory of the exciton spectrum, which is first shown to account for the size dependence of the fundamental gap reported previously in the literature. The theoretical Stokes shift presented as a function of the gap shows a good agreement with the experimental data, indicating that the measured Stokes shift indeed arises from the electron-hole exchange interaction.Comment: 8 pages, 4 figures, LaTe

El álbum poético en portugués y en español: sinergia estética entre palabras e ilustraciones

Este estudo procurou problematizar a relação textual que se observa entre a palavra e a imagem em um tipo de texto especialmente concebido para crianças: o álbum poético. Para tal, utilizamos alguns exemplos textuais significativos desse subgênero literário/editorial ainda em emergência tanto em Portugal quanto na Espanha, e propusemos uma definição e uma caracterização baseadas no comentário de sequências poéticas nas quais a ilustração sustenta o conteúdo verbal. Efetivamente, centrando a atenção no álbum poético de potencial recepção infanto-juvenil, sugere-se uma análise de diversos títulos de autoria portuguesa e espanhola, assente em uma leitura dialógica do texto verbal e do visual. A sinergia que se concretiza entre as duas componentes enunciadas alicerça essa nova construção estética que tem, na verdade e na sua essência, a poesia como matriz e, em larga medida, é devedora dos efeitos expressivos da metáfora.This study aimed to discuss the relation between words and images in a type of text especially directed to children: the picture-poetry book. From significant examples of this literary subgenre still emerging in both Portugal and Spain, we propose a definition and characterization based on the review of poetic sequences in which illustrations support the verbal content. By focusing on picture-poetry books potentially aimed for adolescents and children, we present an analysis of several titles by Portuguese and Spanish authors, based on the dialogic reading between verbal and visual texts. The synergy found between these two components creates de foundantions of a new aesthetic construction which, in truth and in essence, has poetry as its matrix and owes its expressive effects to metaphors.Este estudio ha tenido como objetivo discutir la relación textual que existe entre la palabra y la imagen en un tipo texto especialmente creado para niños: el álbum poético.

Where you look matters for body perception: Preferred gaze location contributes to the body inversion effect

The Body Inversion Effect (BIE; reduced visual discrimination performance for inverted compared to upright bodies) suggests that bodies are visually processed configurally; however, the specific importance of head posture information in the BIE has been indicated in reports of BIE reduction for whole bodies with fixed head position and for headless bodies. Through measurement of gaze patterns and investigation of the causal relation of fixation location to visual body discrimination performance, the present study reveals joint contributions of feature and configuration processing to visual body discrimination. Participants predominantly gazed at the (body-centric) upper body for upright bodies and the lower body for inverted bodies in the context of an experimental paradigm directly comparable to that of prior studies of the BIE. Subsequent manipulation of fixation location indicates that these preferential gaze locations causally contributed to the BIE for whole bodies largely due to the informative nature of gazing at or near the head. Also, a BIE was detected for both whole and headless bodies even when fixation location on the body was held constant, indicating a role of configural processing in body discrimination, though inclusion of the head posture information was still highly discriminative in the context of such processing. Interestingly, the impact of configuration (upright and inverted) to the BIE appears greater than that of differential preferred gaze locations

The North American tree-ring fire-scar network

Fire regimes in North American forests are diverse and modern fire records are often too short to capture important patterns, trends, feedbacks, and drivers of variability. Tree-ring fire scars provide valuable perspectives on fire regimes, including centuries-long records of fire year, season, frequency, severity, and size. Here, we introduce the newly compiled North American tree-ring fire-scar network (NAFSN), which contains 2562 sites, >37,000 fire-scarred trees, and covers large parts of North America. We investigate the NAFSN in terms of geography, sample depth, vegetation, topography, climate, and human land use. Fire scars are found in most ecoregions, from boreal forests in northern Alaska and Canada to subtropical forests in southern Florida and Mexico. The network includes 91 tree species, but is dominated by gymnosperms in the genus Pinus. Fire scars are found from sea level to >4000-m elevation and across a range of topographic settings that vary by ecoregion. Multiple regions are densely sampled (e.g., >1000 fire-scarred trees), enabling new spatial analyses such as reconstructions of area burned. To demonstrate the potential of the network, we compared the climate space of the NAFSN to those of modern fires and forests; the NAFSN spans a climate space largely representative of the forested areas in North America, with notable gaps in warmer tropical climates. Modern fires are burning in similar climate spaces as historical fires, but disproportionately in warmer regions compared to the historical record, possibly related to under-sampling of warm subtropical forests or supporting observations of changing fire regimes. The historical influence of Indigenous and non-Indigenous human land use on fire regimes varies in space and time. A 20th century fire deficit associated with human activities is evident in many regions, yet fire regimes characterized by frequent surface fires are still active in some areas (e.g., Mexico and the southeastern United States). These analyses provide a foundation and framework for future studies using the hundreds of thousands of annually- to sub-annually-resolved tree-ring records of fire spanning centuries, which will further advance our understanding of the interactions among fire, climate, topography, vegetation, and humans across North America

‘‘The Soldiers Came to the House’’: Young Children’s Responses to The Colour of Home

This article begins by reflecting on the present refugee crisis and its relevance to children in the UK. It identifies the need for teaching about the refugee experience to young children and argues that literature can provide a conduit for this. Sincethemillenniumtherehasbeenarapidincreaseinthenumberofbookspublished forchildren whichtake thisastheir theme, aimed atever-youngerreaders.Takingasa case study The Colour of Home by Mary Hoffman, a picturebook commonly used in lower primary classrooms, the article considers how this text promotes understanding and validates the circumstances of refugees. It closely examines the motivations and aims of the writer, how the book was mediated by teachers in the primary classroom, and how refugee and non-refugee children read and responded to it. Findings are presented from an interview with Mary Hoffman herself, juxtaposed with data from threeclassroomssuggestingthatpupilsgainedvaluableinsightintoacomplicatedand controversial issue. However the research concludes that viewing children through a refugee/non-refugee binary was reductive in not recognising the multi-layered nuances of meaning which were constructed by young readers who brought to bear a wide variety of individual life and family experiences. Furthermore, teachers in the study played a powerful role in mediating the texts when sharing them in the classroom, and devised a selection of stimulating resources to provoke reader response in terms of empathy, ‘‘social action’’, and some critical literacy

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised
