Abstract:
AbstractThe extent to which aesthetic preferences are ‘innate’ has been highly debated (Reber, Schwarz, & Winkielman, Personality and Social Psychology Review, 8(4), 364–382, 2004). For some types of visual stimuli infants look longer at those that adults prefer. It is unclear whether this is also the case for colour. A lack of relationship in prior studies between how long infants look at different colours and how much adults like those colours might be accounted for by stimulus limitations. For example, stimuli may have been too desaturated for infant vision. In the current study, using saturated colours more suitable for infants, we aim to quantify the relationship between infant looking and adult preference for colour. We take infant looking times at multiple hues from a study of infant colour categorization (Skelton, Catchpole, Abbott, Bosten, & Franklin, Proceedings of the National Academy of Sciences of the United States of America, 114(21), 5545–5550, 2017) and then measure adult preferences and compare these to infant looking. When colours are highly saturated, infants look longer at colours that adults prefer. Both infant looking time and adult preference are greatest for blue hues and are least for green-yellow. Infant looking and adult preference can be partly summarized by activation of the blue-yellow dimension in the early encoding of human colour vision. These findings suggest that colour preference is at least partially rooted in the sensory mechanisms of colour vision, and more broadly that aesthetic judgements may in part be due to underlying sensory biases.

Abstract:
AbstractAlmost 40 years ago, Davida Teller developed the forced-choice preferential looking method for studying infant visual capabilities and used it to study infant color vision. About 10 years ago, she used infant looking preferences to study infant color perception. Here, we examine four data sets in which the infant looking preference was measured using a wide range of saturated colors. Three of those data sets, from papers by Marc Bornstein and by Davida Teller and Anna Franklin and their respective collaborators, were fit successfully using MacLeod and Boynton’s model of the equiluminant plane in color space, in spite of the varied luminances used in those studies. A fourth data set, from a paper by Zemach, Chang, and Teller, was less well fit by that model. Apparently, infants are able to ignore luminance, and pay attention just to the color of stimuli. These results are discussed in the context of Davida Teller’s work on the philosophy of vision science.

Abstract:
Purpose This study aims to examine the observer’s role in “infant psychophysics”. Infant psychophysics was developed because the diagnosis of perceptual deficits should be done as early in a patient’s life as possible, to provide efficacious treatment and thereby reduce potential long-term costs. Infants, however, cannot report their perceptions. Hence, the intensity of a stimulus at which the infant can detect it, the “threshold”, must be inferred from the infant’s behavior, as judged by observers (watchers). But whose abilities are actually being inferred? The answer affects all behavior-based conclusions about infants’ perceptions, including the well-proselytized notion that auditory stimulus-detection thresholds improve rapidly during infancy. Design/methodology/approach In total, 55 years of infant psychophysics is scrutinized, starting with seminal studies in infant vision, followed by the studies that they inspired in infant hearing. Findings The inferred stimulus-detection thresholds are those of the infant-plus-watcher and, more broadly, the entire laboratory. The thresholds are therefore tenuous, because infants’ actions may differ with stimulus intensity; expressiveness may differ between infants; different watchers may judge infants differently; etc. Particularly, the watcher’s ability to “read” the infant may improve with the infant’s age, confounding any interpretation of perceptual maturation. Further, the infant’s gaze duration, an assumed cue to stimulus detection, may lengthen or shorten nonlinearly with infant age. Research limitations/implications Infant psychophysics investigators have neglected the role of the observer, resulting in an accumulation of data that requires substantial re-interpretation. Altogether, infant psychophysics has proven far too resilient for its own good. Originality/value Infant psychophysics is examined for the first time through second-order cybernetics. The approach reveals serious unresolved issues.

Abstract:
When infants are tested with stimuli of various chromaticities embedded in a dark or achromatic (white) surround, they show maximal preference for stimuli of maximal colorimetric purity, and minimal preference for achromatic stimuli. We investigated how this pattern of preferences changes with changes of surround chromaticity. Sixteen-week-old infants were tested in two experimental conditions. The surrounds in the first condition were red and white; and in the second condition green and white. The three test stimuli varied in colorimetric purity from white to red in the first condition, and from white to green in the second condition. A test stimulus that appeared achromatic to adults when viewed in the chromatic surround was included. Infant spontaneous looking preferences changed with changes of surround chromaticity. The changes were consistent with the conclusion that infant looking behavior is governed by a preference for the stimuli that differ maximally in purity from the surround. The implications of this pattern of results are discussed.

Abstract:
Background: Docosahexaenoic acid (DHA), choline and uridine-5-monophosphate (UMP) are important brain nutrients which form phosphatidylcholine, the most abundant brain membrane phospholipid. DHA, choline and UMP supplementation increases rodent brain phospholipids, synaptic components, functional brain connectivity and cognitive performance. This novel pilot study supplemented infants at risk of neurological impairment (ARNI) with a nutrient combination containing these neurotrophic compounds. Aims: 1) In a double blind randomised control trial (RCT), investigate if intake of a specific nutrient combination improves neurodevelopmental and visual outcome in infants ARNI. 2) Using novel measures of cortical visual function, investigate the effect of perinatal brain injury severity, gestational age at birth and sex upon visuocognitive development in infants at risk of neurodevelopmental impairment. Method: Recruitment was from UK neonatal units. Eligibility: ≤ 31 weeks, weight < 9th percentile; < 31 weeks with ≥ Grade II intraventricular haemorrhage (IVH) or preterm white matter injury (PWMI); 31-40 weeks with ≥ Grade II IVH or PWMI, ≥ Sarnat Grade II HIE or defined brain MRI abnormalities. Stratification was by sex, gestation and brain injury severity. Randomised infants received neurotrophic supplementation or placebo, for 2 years. Primary outcome was Bayley Scales of Infant Development III (BSID III) composite cognitive score (CCS) after 2 years. Secondary outcomes included BSID III composite language score (CLS) and BSID III composite motor score (CMS). Cortical visual measures were pattern reversal visual event related potential (PR-VERP) latency (transient and calculated), orientation reversal visual event related potentials (OR-VERP), and the Fixation Shift test (FS). Functional behavioural vision was assessed using the Atkinson Battery of Child Development for Examining Functional Vision (ABCDEFV). Local Ethics Committee approval was granted. Results: 62 neonates were recruited. After 2 years, mean CCS in the intervention group was 87.7 (SD 20.4) and 81.6 (SD 18.5) in the placebo group (mean difference = 2.28, p=0.13; -0.2, 18.2). Mean CLS in the intervention group was 91.5 (SD 20.1) and 83.2 (SD 19.6) in the placebo group (mean difference = 2.74, p=0.1; -2.4, 18.3). CMS was similar in both groups. In relation to trial visual outcome measures, more infants in the placebo group gave a statistically significant OR-VERP response than in the intervention group (p=0.03). There were no statistically significant differences between the placebo and intervention on any other trial visual outcome measure. Cohort analyses indicate that transient PR-VERP latency is prolonged in children at risk of neurodevelopmental disability compared to typically developing infants (mean difference = -23.3, p=0.015, 95% CI -42.10 - -4.54). Calculated PR-VERP latency is prolonged to an even greater extent in children at risk of neurodevelopmental disability compared to typically developing infants (mean difference -148.6, p=0.000, 95% CI -179.7- -117.43), and remains prolonged across the age range tested. Conclusions: 1) The difference in CCS and CLS between intervention and placebo groups represents a clinically significant effect size. Use of neurotrophic micronutrient supplementation in infants ARNI warrants exploration in a large multicentre RCT. 2) Calculated PR-VERP latency may be a more appropriate outcome measure of cortical visual function than transient PR-VERP latency in infants at risk of neurodevelopmental disability.

Abstract:
Previous work has demonstrated that infant visual short-term memory (VSTM) capacity increases dramatically between 6 and 10 months of life (Ross-Sheehy, S., Oakes, L. M., & Luck, S. J. (2003). The development of visual short-term memory capacity in infants. Child Development, 74, 1807-1822). However, it is unclear if this increase is a function of improving memory abilities, or alternatively, if it is a function of improving attentional abilities. Moreover, it is currently unknown if infants, like adults, can use attention to form stable VSTM representations in situations where they would otherwise fail. Four experiments explored the relationship between visual attention and VSTM in 5.5- and 10-month-old infants. Results indicated that 1) 10-month-old infants are able to use attention to selectively encode items into VSTM, 2) this ability does not appear to be present in younger infants, 3) this ability does not appear to interact with the complexity of the test array, and 4) attentional facilitation requires a relatively salient cue. Taken together, these results are the first to demonstrate that infant VSTM representations can be mediated by visual attention, and that this mediation relies on relatively well-developed visual attention mechanisms.

Resumo: Objetivos: Analisar o desenvolvimento visual de lactentes, por meio da identificação dos comportamentos visuais mais freqüentes nos três primeiros meses de vida e identificar qual o mês mais favorável para realização da triagem visual. Método: Estudo analítico, seccional, realizado no CEPRE/FCM/UNICAMP, com lactentes saudáveis, nos três primeiros meses de vida. O instrumento utilizado foi o Método de Avaliação da Conduta Visual de Lactentes. A análise estatística foi realizada pelo modelo loglinear para associações entre o sexo, faixa etária e as respostas dos lactentes em cada prova. Resultados: A amostra do estudo foi de 1073 lactentes (50,1% meninos e 49,9% meninas), sendo no primeiro mês 688 lactentes, no segundo mês 229 e no terceiro mês 156. Verificou-se diferença significante entre a freqüência das respostas dos lactentes e a faixa etária nas provas P3 (sorriso social), P5 (seguimento visual vertical), P7 (exploração visual da mão), P8 (movimentos dos membros ao visualizar objeto) e P9 (estender o braço na direção do objeto visualizado). Na P5 verificou-se freqüência de respostas positivas acima de 95% a partir do segundo mês. Não houve diferença significante nas provas P1-contato de olho, P2- fixação visual, P4- seguimento visual horizontal e P6- observação visual do ambiente. Estas provas apresentaram freqüência superior a 99% já no primeiro mês. A P9 foi significante quando comparada ao sexo. A comparação do sucesso das respostas dos lactentes na aplicação do instrumento de triagem com os meses foi significante entre o primeiro e segundo e entre primeiro e terceiro meses. Conclusão: A triagem do comportamento visual de lactentes deve ser realizada entre o segundo e terceiro meses de vida, pelas provas: P1, P2, P4, P5 e P6, como ação de promoção da saúde ocular e detecção precoce de alterações visuais
Abstract: Objectives: To analyze the visual development of infants, by identifying the most frequent visual behaviors in the first three months and to identify the most favorable month for carrying out visual screening. Method: Sectional analytic study, carried out at CEPRE/FCM/UNICAMP, with healthy infants, during their first trimester. The instrument used was the Assessment Method of Infant Visual Behavior. Statistical analysis was carried out using the log-linear model of association between sex, age and infant responses to each test. Results: The study sample was made up of 1073 infants(of which 50,1% were boys and 49,9% girls), with 688 first month infants, 229 second month infants and 156 third month infants. The results showed a significant difference among frequency of infant responses and age for the following tests: T3 (social smile), T5 (vertical visual tracking), T7 (visual exploration of hands), T8 (arm and leg movements when looking at object) and T9 (arm extension towards the object being visualized). For T5, the frequency of positive answers was more than 95% after the second month. There was no significant difference for tests T1 - eye contact, T2 - visual fixation, T4 - horizontal visual tracking and T6 - visual observation of environment. These tests presented frequency higher than 99% already at the first month. T9 was significant when compared to sex. Comparison of the success of newborn infants for the application of the screening instrument monthly was significant between the first and second months and between the first and third months. Conclusion: Screening of visual behavior of infants should be carried out between the second and third months of life using the tests: T1, T2, T4, T5 and T6, as an action for ocular health promotion and early detection of visual alterations

Resumo: Objetivos: Determinar o desenvolvimento da acuidade visual de grades binocular e monocular, mensuradas com o Lea Gratings, prover uma base idade-dependente por esta técnica em uma coorte de crianças saudáveis e comparar os resultados obtidos por este teste com os obtidos com os Cartões de Acuidade de Teller. Método: Tratou-se de estudo prospectivo e longitudinal, descritivo e analítico, da acuidade visual de resolução de grades de um grupo de lactentes, nos três primeiros meses de vida e no período entre 12 e 24 meses. Considerou-se, como critérios de inclusão, lactentes que foram nascidos a termo e adequados para a idade gestacional, com um mês de idade cronológica e residentes na região metropolitana de Campinas, que apresentaram o Reflexo Vermelho presente ao nascimento. A acuidade visual de resolução de grades foi mensurada por meio do teste Lea Gratings, mês a mês, e, a partir dos 12 meses, também por meio dos Cartões de Acuidade de Teller, quando foram descartadas alterações oftalmológicas nos participantes do estudo. A amostra foi constituída de 133 lactentes e a análise dos resultados foi realizada utilizando-se o Statistical Package for Social Sciences for Personal Computer (SPSS 16.0). Os valores de acuidade (CPD) foram apresentados em distribuição de frequência e para determinação da média e do desvio padrão, os dados foram transformados em escala de uma oitava. Para comparação da acuidade visual entre as idades foi utilizada a análise de variância para medidas repetidas e o de Wilcoxon para comparação das medidas entre os olhos para amostras relacionadas. A correlação entre os resultados obtidos pelos dois testes foi avaliada pelo Coeficiente de Correlação de Spearman. Resultados: Os valores de acuidade visual binocular foram crescentes, sendo obtida no primeiro mês a média de 0,55 cpd (±0,70), de 1,35 cpd (±0,69) no segundo mês e de 3,11 cpd (±0,54) no terceiro mês. A partir dos 12 meses, as médias dos valores de acuidade visual binocular e monocular - foram, respectivamente, de 14,41 cpd (±0,25) e de 12,03 cpd (±0,39) nas crianças com idade entre 12 e 14 meses, de 14,10 cpd (±0,27) e de 10,79 cpd (±0,42) em crianças com idade entre 15 e 18 meses e de 15,50 cpd (±0,13) e de 13,42 cpd (±0,26) em crianças com idade entre 19 e 24 meses. Os resultados da análise de variância demonstraram diferenças significativas nos valores de acuidade visual entre todas as idades. Os coeficientes de Correlação de Spearman entre os testes Lea Gratings e Cartões de Acuidade de Teller foram de 0,53505 e de 0,65175 para, respectivamente, as medidas binocular e monocular. Conclusão: O teste foi capaz de avaliar a evolução da acuidade visual no primeiro trimestre de vida e no período entre 12 a 24 meses, e permitiu o fornecimento de uma base idade-dependente por esta técnica em uma coorte de lactentes saudáveis até o período de 12 meses. A comparação entre os dois testes de acuidade visual de grades demonstrou correlação positiva
Abstract: Purpose: This study aims to determine the development of the binocular and monocular grating acuity with Lea Gratings, to established age-related norms for this method in a health children cohort and comparing the results obtained by this test with those obtained with the Teller Acuity Cards. Methods: This was a prospective and longitudinal study, descriptive and analytic, of infant grating visual acuity in the first three months of life and between the ages 12 and 24 months. The sample was composed of infants that met the following criteria: full-term infants appropriate for gestational age, with a chronological age of one month, residents in the Campinas metropolitan region, born with positive red reflex and whose parents consented to participate in this study. The grating acuity of each infant was measured three times at regular intervals, using Lea Gratings, and after 12 months, also with the Teller Acuity Cards, when a complete ophthalmologic examination was conducted to reject any visual alteration. The final sample was composed of 133 infants and the results were analyzed with the Package for Social Sciences for the Personal Computer (SPSS 16.0). The grating acuity results were stated in frequency tables and converted into a one-octave scale for statistical calculation. Repeated measure analysis of variance was applied to compare the grating acuity results among ages. The Wilcoxon test was used to compare the measures between the eyes in related samples and the Spearman Correlation was applied to evaluate the results obtained with the two tests. Results: The binocular grating acuity measures were crescent. In the first month, the mean acuity was 0.55 cpd (±0.70); in the second month, the mean acuity was 1.35 cpd (±0.69) and in the third month it was 3.11 (±0.54). After 12 months, the means of binocular and monocular acuity were, respectively, 14.41 cpd (±0.25) and 12.03 cpd (±0.39) in children between ages 12 and 14 months; 14.10 cpd (±0.27) and 10.79 cpd (±0.42) in children between ages 15 and 18 months; 15.50 cpd (±0.13) and 13.42 cpd (±0.26) in children between ages 19 and 24 months. Analysis of variance to repeated measures indicated differences between the measures of grating acuity in all ages. The coefficient of Spearman Correlation between the tests Lea Gratings and Teller Acuity Cards was respectively 0.53505 and 0.65175 for binocular and monocular measures. Conclusions: This test was capable to assess the evolution of grating acuity in the first three months of life and between 12 and 24 months, and established age-related norms for this method in a health children cohort until 12 months age. The comparison between the two tests of grating acuity demonstrated positive correlation

The primary function of vision is related to achievements in infant development. The visual behavior is known to be acquired once visual stimuli are processed by retinal cells and then transmitted to the cerebral cortex by neurovisual pathways. This neuromaturational process progresses as visual stimuli are received by the neurons and synapses are moved from one nerve cell to another, thus promoting a normal visual development. The prematurity of the infant has been described to be an important indicator of risk for morbidity during the visuomotor development. Infants likely to have visuomotor impairment during this period should thus be provided with special follow-up. In this regard, this longitudinal study aims to assess the visuomotor behavior in infants at risk for disorders during the first three months of life. The infants were recruited from the Program for Detecting Audiological Disorders in Newborns (DAANE), in the Center of Studies and Research on Rehabilitation Prof. Dr. Gabriel Porto at the School of Medical Sciences of the University Estadual of Campinas (CEPRE/FCM/UNICAMP). The participants were evenly divided into two groups of 21 infants. The experimental group was composed of preterm infants with gestational age under 37 full weeks, and a correected age of 1 to 3 months. The control group consisted of fullterm infants with gestational age ranging from 37 full weeks to 41 weeks and 6 days, and a chronological age of 1 to 3 months. Each infant was assessed three times at regular intervals through the Method for the Assessment of Infant Visual Behavior. The data was stored in a file form for the data bank of the program Statistical Package for Social Sciences for Personal Computer (Versão 14). The Cochran s Q-test was applied to compare the three months (assessment) in each group, and the Yates test was used to compare the two groups in each month. The results indicated that although linearity and sequence in visuomotor achievements were similar between the two groups, the rhythm and pattern of visuomotor development were different between them. In the first two months of life, fullterm infants were shown to acquire the great majority of the oculomotor and apendicular functions in a more rapid and frequent way. These results point to the importance of correcting gestational age when assessing the visuomotor behavior of infants at risk. This study provides a material for informational and instrumental support for parents regarding the normal visual development of infants from birth to the sixth month of life. Furthermore, this study contributes towards a further understanding of the visuomotor development of preterm infants, and promotes an opportune detection of possible signs indicative of visuomotor impairment so that the infant can receive a timely diagnosis.
A função primária da visão está ligada às conquistas do desenvolvimento infantil. Sabese que o desenvolvimento do comportamento visual ocorre diante da recepção e captação dos estímulos visuais pelas células retinianas e transmissão destes para o córtex cerebral pelas vias neurológicas da visão. Este processo de maturação neurológica ocorre à medida que chegam os estímulos visuais e mais sinapses vão sendo realizadas pelas células neurais, favorecendo o desenvolvimento visual normal. A prematuridade é reconhecida como importante indicador de risco para morbidades sobre o desenvolvimento infantil e desenvolvimento visuomotor. Desta forma, um acompanhamento especial deve ser destinado aos lactentes com chances de apresentar algum comprometimento visuomotor neste período. Diante do exposto, este estudo tem como objetivo avaliar o comportamento visuomotor de lactentes com indicador de risco para alterações no desenvolvimento, em seguimento longitudinal, durante o primeiro trimestre de vida. Os lactentes selecionados são aqueles que fazem parte do Programa de Detecção de Alterações Audiológicas em Neonatos (DAANE), no Centro de Estudos e Pesquisas em Reabilitação Prof. Dr. Gabriel Porto , da Faculdade de Ciências Médicas da Universidade Estadual de Campinas (CEPRE/FCM/UNICAMP). A amostra do estudo é composta por dois grupos independentes de 21 lactentes cada um. O grupo experimental é composto por lactentes pré-termo com idade gestacional menor que 37 semanas completas de gestação e com idade corrigida entre 1 e 3 meses. O grupo controle tem população equivalente, porém são lactentes a termo com idade gestacional entre 37 semanas completas e 41 semanas e 6 dias, com idade cronológica entre 1 e 3 meses. Nesta proposta, cada lactente foi avaliado três vezes, com periodicidade definida, por meio do Método de Avaliação da Conduta Visual de Lactentes. Os dados foram armazenados nos moldes de arquivo para o banco de dados do programa Statistical Package for Social Sciences for Personal Computer (Versão 14) e receberam uma análise estatística, utilizando-se a prova Q de Cochran para comparar os três meses (avaliações) de cada grupo e o teste de Yates para comparar diretamente os dois grupos em cada mês. Os resultados das avaliações demonstraram que, apesar da linearidade e da sequência das aquisições visuomotoras serem semelhantes entre lactentes a termo e lactentes pré-termo, o ritmo e o padrão de desenvolvimento visuomotor de lactentes pré-termo diferencia-se dos lactentes a termo. A aquisição da grande maioria das funções oculomotoras e apendiculares no primeiro e segundo meses de vida ocorre de forma mais rápida e freqüente nos lactentes a termo. Frente a estes resultados, discute-se a importância da correção da idade gestacional nos processos avaliativos do comportamento visuomotor de lactentes de risco. Além disso, o presente estudo apresentou um material de suporte informacional e instrumental destinado aos pais, acerca do desenvolvimento visual normal até o sexto mês de vida. Desta forma, este estudo contribuiu para um maior conhecimento sobre o comportamento visuomotor de lactentes pré-termo, bem como possibilitou a detecção oportuna de possíveis sinais indicativos de comprometimento visuomotor e encaminhamento a serviços médicos para diagnóstico.

Abstract:
Movement and pose assessment of newborns lets experienced pediatricians predict neurodevelopmental disorders, allowing early intervention for related diseases. However, most of the newest AI approaches for human pose estimation methods focus on adults, lacking publicly benchmark for infant pose estimation. In this paper, we fill this gap by proposing infant pose dataset and Deep Aggregation Vision Transformer for human pose estimation, which introduces a fast trained full transformer framework without using convolution operations to extract features in the early stages. It generalizes Transformer + MLP to high-resolution deep layer aggregation within feature maps, thus enabling information fusion between different vision levels. We pre-train AggPose on COCO pose dataset and apply it on our newly released large-scale infant pose estimation dataset. The results show that AggPose could effectively learn the multi-scale features among different resolutions and significantly improve the performance of infant pose estimation. We show that AggPose outperforms hybrid model HRFormer and TokenPose in the infant pose estimation dataset. Moreover, our AggPose outperforms HRFormer by 0.8 AP on COCO val pose estimation on average. Our code is available at github.com/SZAR-LAB/AggPose.

Abstract:
Application of 3D technologies to the wide range of Geosciences knowledge domains is well underway. These have been operationalized in workflows of the hydrocarbon sector for a half-century, and now in mining for over two decades. In Geosciences, algorithms, structured workflows and data integration strategies can support compelling Earth models, however challenges remain to meet the standards of geological plausibility required for most geoscientific studies. There is also missing links in the institutional information infrastructure supporting operational multi-scale 3D data and model development. Canada in 3D (C3D) is a vision and road map for transforming the Geological Survey of Canada's (GSC) work practice by leveraging emerging 3D technologies. Primarily the transformation from 2D geological mapping, to a well-structured 3D modelling practice that is both data-driven and knowledge-driven. It is tempting to imagine that advanced 3D computational methods, coupled with Artificial Intelligence and Big Data tools will automate the bulk of this process. To effectively apply these methods there is a need, however, for data to be in a well-organized, classified, georeferenced (3D) format embedded with key information, such as spatial-temporal relations, and earth process knowledge. Another key challenge for C3D is the relative infancy of 3D geoscience technologies for geological inference and 3D modelling using sparse and heterogeneous regional geoscience information, while preserving the insights and expertise of geoscientists maintaining scientific integrity of digital products. In most geological surveys, there remains considerable educational and operational challenges to achieve this balance of digital automation and expert knowledge. Emerging from the last two decades of research are more efficient workflows, transitioning from cumbersome, explicit (manual) to reproducible implicit semi-automated methods. They are characterized by integrated and iterative, forward and reverse geophysical modelling, coupled with stratigraphic and structural approaches. The full impact of research and development with these 3D tools, geophysical-geological integration and simulation approaches is perhaps unpredictable, but the expectation is that they will produce predictive, instructive models of Canada's geology that will be used to educate, prioritize and influence sustainable policy for stewarding our natural resources. On the horizon are 3D geological modelling methods spanning the gulf between local and frontier or green-fields, as well as deep crustal characterization. These are key components of mineral systems understanding, integrated and coupled hydrological modelling and energy transition applications, e.g. carbon sequestration, in-situ hydrogen mining, and geothermal exploration. Presented are some case study examples at a range of scales from our efforts in C3D.

Abstract:
In India, severe anemia has been one of the causes of high maternal mortality and death of newborns and infants due to low birthweight. The prevalence of anemia among women ages 15–44 is extremely high. The Government of India has provided iron and folic acid tablets (IFA) as a prophylaxis against nutritional anemia among pregnant women as part of the Child Survival and Safe Motherhood program and will continue to do so in the Reproductive and Child Health package. This paper presents findings of both qualitative and quantitative research conducted among pregnant women to investigate the extent of distribution and use, information provision, and knowledge and perceptions regarding IFA tablets and reasons for nonuse. The study shows that consumption rate of IFA tablets is high if women are knowledgeable and have positive experiences after taking the tablets. Findings suggest that more accurate and complete information should be provided to pregnant women while distributing IFA tablets along with health and nutritional education messages. At the same time, follow-up visits and counseling are essential to address symptoms that are not related to IFA.
