Quantifying the Water Footprint: Growing Crops Sustainably in Northwest India

University Research Scholarship - School of ENRWhen the Green Revolution was ushered in India in the 1960s, the historically-diverse and rain-fed agricultural practices followed for millennia changed dramatically. The decline in groundwater resources across Northern India, especially from agricultural production, is a well known environmental concern and a critical one to address. There is much less awareness that the temporal and spatial distribution of freshwater across the globe is greatly affected by production chains and global exchange. This study applies the concept of water footprint analysis to compute the water demands of the process of growing two principal crops (wheat and rice) in Punjab, India. As a quantitative indicator of fresh water use, the water footprint illuminates the gap between Punjab's natural resource supply and the state's intense water demands. The dependence on aquifers to irrigate croplands has only replaced the alarming issue of food scarcity, with water scarcity, and thus, renewed concerns of famine. The water footprint of wheat and rice from planting to harvest, only represents one snapshot of the entire picture of consumptive water use. As this is only an application of footprint accounting, additional research that incorporates the production process that includes transportation, processing, and export would create a more complete assessment of water resources allocated for agriculture.No embarg

Picture-naming in American Sign Language: an electrophysiological study of the effects of iconicity and structured alignment

A picture-naming task and ERPs were used to investigate effects of iconicity and visual alignment between signs and pictures in American Sign Language (ASL). For iconic signs, half the pictures visually overlapped with phonological features of the sign (e.g., the fingers of CAT align with a picture of a cat with prominent whiskers), while half did not (whiskers are not shown). Iconic signs were produced numerically faster than non-iconic signs and were associated with larger N400 amplitudes, akin to concreteness effects. Pictures aligned with iconic signs were named faster than non-aligned pictures, and there was a reduction in N400 amplitude. No behavioral effects were observed for the control group (English speakers). We conclude that sensory-motoric semantic features are represented more robustly for iconic than non-iconic signs (eliciting a concreteness-like N400 effect) and visual overlap between pictures and the phonological form of iconic signs facilitates lexical retrieval (eliciting a reduced N400)

Resuscitative Endovascular Balloon Occlusion of the Aorta and Resuscitative Thoracotomy in Select Patients with Hemorrhagic Shock: Early Results from the American Association for the Surgery of Trauma’s Aortic Occlusion in Resuscitation for Trauma and Acute Care Surgery Registry

Background Aortic occlusion is a potentially valuable tool for early resuscitation in patients nearing extremis or in arrest from severe hemorrhage. Study Design The American Association for the Surgery of Trauma\u27s Aortic Occlusion in Resuscitation for Trauma and Acute Care Surgery registry identified trauma patients without penetrating thoracic injury undergoing aortic occlusion at the level of the descending thoracic aorta (resuscitative thoracotomy [RT] or zone 1 resuscitative endovascular balloon occlusion of the aorta [REBOA]) in the emergency department (ED). Survival outcomes relative to the timing of CPR need and admission hemodynamic status were examined. Results Two hundred and eighty-five patients were included: 81.8% were males, with injury due to penetrating mechanisms in 41.4%; median age was 35.0 years (interquartile range 29 years) and median Injury Severity Score was 34.0 (interquartile range 18). Resuscitative thoracotomy was used in 71%, and zone 1 REBOA in 29%. Overall survival beyond the ED was 50% (RT 44%, REBOA 63%; p = 0.004) and survival to discharge was 5% (RT 2.5%, REBOA 9.6%; p = 0.023). Discharge Glasgow Coma Scale score was 15 in 85% of survivors. Prehospital CPR was required in 60% of patients with a survival beyond the ED of 37% and survival to discharge of 3% (all p \u3e 0.05). Patients who did not require any CPR before had a survival beyond the ED of 70% (RT 48%, REBOA 93%; p \u3c 0.001) and survival to discharge of 13% (RT 3.4%, REBOA 22.2%, p = 0.048). If aortic occlusion patients did not require CPR but presented with hypotension (systolic blood pressure \u3c90 mmHg; 9% [65% RT; 35% REBOA]), they achieved survival beyond the ED in 65% (p = 0.009) and survival to discharge of 15% (RT 0%, REBOA 44%; p = 0.008). Conclusions Overall, REBOA can confer a survival benefit over RT, particularly in patients not requiring CPR. Considerable additional study is required to definitively recommend REBOA for specific subsets of injured patients

Comparison of acarological risk metrics derived from active and passive surveillance and their concordance with tick-borne disease incidence

Tick-borne diseases continue to threaten human health across the United States. Both active and passive tick surveillance can complement human case surveillance, providing spatio-temporal information on when and where humans are at risk for encounters with ticks and tick-borne pathogens. However, little work has been done to assess the concordance of the acarological risk metrics from each surveillance method. We used data on Ixodes scapularis and its associated human pathogens from Connecticut (2019–2021) collected through active collections (drag sampling) or passive submissions from the public to compare county estimates of tick and pathogen presence, infection prevalence, and tick abundance by life stage. Between the surveillance strategies, we found complete agreement in estimates of tick and pathogen presence, high concordance in infection prevalence estimates for Anaplasma phagocytophilum, Borrelia burgdorferi sensu stricto, and Babesia microti, but no consistent relationships between actively and passively derived estimates of tick abundance or abundance of infected ticks by life stage. We also compared nymphal metrics (i.e., pathogen prevalence in nymphs, nymphal abundance, and abundance of infected nymphs) with reported incidence of Lyme disease, anaplasmosis, and babesiosis, but did not find any consistent relationships with any of these metrics. The small spatial and temporal scale for which we had consistently collected active and passive data limited our ability to find significant relationships. Findings are likely to differ if examined across a broader spatial or temporal coverage with greater variation in acarological and epidemiological outcomes. Our results indicate similar outcomes between some actively and passively derived tick surveillance metrics (tick and pathogen presence, pathogen prevalence), but comparisons were variable for abundance estimates

Food Security Status of Households in Appalachian Ohio with Children in Head Start

This study measured food security and hunger of households involved in Head Start in a rural Appalachian county and assessed factors that could affect food security and hunger. A convenience sample of households with children enrolled in the Head Start program in Athens County, Ohio, were sampled (n=710), with adults from 297 (42%) households responding. The survey instrument included the 18-question US Household Food Security Survey Module for measuring hunger and food insecurity. Of those responding, 152 households (51.2%) were food secure and 145 (48.8%) were food insecure. Ninety (30.3%) had experienced hunger in the previous 12 months, and 41 (13.8%) households were classified as food insecure with childhood hunger. Hunger was related to a variety of household characteristics and associated with several factors, including participation in food banks, dependence on family members and friends outside of the household for food, lacking reliable transportation, and not having a garden
