Forage Genetic Resources In Brazil, Liana Jank, Mateus F. Santos, Cacilda B. Do Valle, Sanzio C. L. Barrios, Rosangela M. Simeão

IGC Proceedings (1977-2023)

To maintain the largest herd in the world, 214 million heads of beef cattle grazing exclusively on pastures (only 14% finished in feed-lots), Embrapa (Brazilian Agricultural Research Corporation) in Brazil, has intensely invested on forage breeding programs since the 1980s. Nowadays, there are circa thirteen forage grass and legume species being bred at different Embrapa Units around the country and other six Units focusing on collection and research of regional native forages. Breeding depends on good germplasm sources. Therefore, breeding activities in Brazil will remain highly dependent on exotic and native genetic basis maintained in the Germplasm Banks. Despite the …

Forage Production And Utilisation: Forage Production For Improved On-Farm Wealth And Wellness, John Caradus

IGC Proceedings (1977-2023)

It is often overlooked that the world’s largest agricultural land use by far is grassland, where these are mostly grazed by livestock, either domesticated or wild animals. Native grasslands are referred to as savanna (in Africa), steppe (in sub- Artic Eurasia), prairie (in North America), or pampas (in South America). Grasslands contribute to the livelihoods of more than 800 million people (FAO 2000). Native grasslands are maintained by restricted rainfall that reduces the opportunity for succession by forest. Grasslands are not only food for livestock, but also provide a habitat for wildlife, prevent soil erosion, support pollinators, and capture carbon …

Sustainable Use Of Grassland Resources For Improved Livelihoods, Liana Jank, Cacilda Borges Do Valle, Rosangela Maria Simeão, Roberto Giolo De Almeida, Mateus Figueiredo Santos, Sanzio Carvalho Barrios

IGC Proceedings (1977-2023)

Grasslands occupy about 80% of global agricultural land and represent a wide range of ecosystems (Bosi et al., 2020). Pastureland represents approximately 889 million ha in Africa, followed by China (~506 million ha), Oceania (~345 million ha), Asia (~307 million ha, excluding China and India), United States (~252 million ha) and Brazil (~149 million ha) (Goldewijk et al. 2017; Bosi et al. 2020; Landau et al., 2020). Rangelands alone are the world largest land surface, and in 28 countries they represent more than 60 percent of total land area (FAO, 2009). The livelihoods of almost one billion people depend on …

Exploring The Information Base Needed For Sustainable Management Of Rangeland Resources For Improved Livelihoods, K. I. Johnsen, M. Niamir-Fuller, A. Bensada, A. Waters-Bayer

IGC Proceedings (1977-2023)

Pastoralism is one of the most sustainable production systems worldwide and plays a major role in safeguarding ecosystem services and biodiversity in rangelands. The unique biological and cultural diversity of rangelands contributes to goods, services and knowledge that benefit humans also beyond the herding communities.

Yet data currently available on grassland, forestry, agriculture and livestock are inadequate for informing policymaking on rangeland-based livestock systems. A review of global environmental assessments, online databases, peer-reviewed literature and international project documents showed that available information seldom disaggregates rangelands from other ecosystems or pastoralists from other rural dwellers. Few peer-reviewed publications address pastoral and …

Animal Agriculture And Climate Change, Lewis Bollard

General – Farm Animal Issues

Earlier this year the prestigious EAT-Lancet Commission called on the world to eat less meat to slow climate change. Three other reports in the last year echoed that message, including two published in Science and Nature, and one produced in partnership with two UN agencies and the World Bank. Even the normally cautious Intergovernmental Panel on Climate Change noted in its October report the “increasing agreement that overall emissions from food systems could be reduced by targeting the demand for meat and other livestock products.” This marks a major change. The climate movement long ignored the inconvenient truth of meat’s …

Lessons From The Pandemic: Engaging Wicked Problems With Transdisciplinary Deliberation, Miles C. Coleman, Susana C. Santos, Joy M. Cypher, Claude Krummenacher, Robert Fleming

Journal of Communication Pedagogy

Some crises, such as those brought on or exposed by the COVID-19 pandemic, are wicked problems—large, complex problems with no immediate answer. As such, they make rich centerpieces for learning with respect to public deliberation and issue-based dialogue. This essay reflects on an experimental, transdisciplinary health and science communication course entitled Comprehending COVID-19. The course represents a collaborative effort among 14 faculty representing 10 different academic departments to create a resource for teaching students how to deliberate the pandemic, despite its attending, oversaturated, fake-news-infused, infodemic. We offer transdisciplinary deliberation as a pedagogical framework to expand communication repertoires in ways useful …

Pedagogy, Protests, And Moving Toward Progress, Nannetta Durnell-Uwechue, Deandre J. Poole, Felton O. Best

Journal of Communication Pedagogy

Our world is in constant flux and educators are at the ship’s helm steering toward what former U.S. Representative John Lewis called “good trouble.” However, in many cases, educators lack the training required to be most effective in doing so. As instructors face student demands to address topics on race and social justice, many educators are unsure about how to respond appropriately to the chants of “No Justice, No Peace!” Thus, this essay explores humanistic and pragmatic approaches for doing so in terms of fostering cultural communication competence when incorporating topics on race and social justice issues in the classroom.

Dengue virus (DENV) is a worldwide health burden, and a safe vaccine is needed. Neutralizing antibodies bind to quaternary epitopes on DENV envelope (E) protein homodimers. However, recombinantly expressed soluble E proteins are monomers under vaccination conditions and do not present these quaternary epitopes, partly explaining their limited success as vaccine antigens. Using molecular modeling, we found DENV2 E protein mutations that induce dimerization at low concentrations (<100 pM) and enhance production yield by more than 50-fold. Cross-dimer epitope antibodies bind to the stabilized dimers, and a crystal structure resembles the wild-type (WT) E protein bound to a dimer epitope antibody. Mice immunized with the stabilized dimers developed antibodies that bind to E dimers and not monomers and elicited higher levels of DENV2-neutralizing antibodies compared to mice immunized with WT E antigen. Our findings demonstrate the feasibility of using structure-based design to produce subunit vaccines for dengue and other flaviviruses.

Boundary Crossing By A Community Of Practice: Tibetan Buddhist Monasteries Engage Science Education, Carol M. Worthman, Ann Cale Kruger, Cindy Achat-Mendes, Tashi Lhamo, Rinchen Wangyal, Gelek Gyatso, Kelsey M. Gray

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

As a globalized world struggles with division and disinformation, engaging across difference has emerged as a major challenge to communication and collaborative action needed to address growing global challenges. As such, the initiative by Tibetan Buddhist leaders to incorporate western science in curricula for monastic education may serve as an important case study that illuminates the conditions and processes at work in genuine cultural outreach and exchange. That project, spearheaded in the Emory-Tibet Science Initiative (ETSI), involves reaching out across two quite different communities of practice, Tibetan Buddhism and science, and the willingness and ability of individuals to cross the …

Binary And Ternary Toxicological Interactions Of Clothianidin And Eight Commonly Used Pesticides On Honey Bees (Apis Mellifera), Yanhua Wang, Yu Cheng Zhu, Wenhong Li, Jianxiu Yao, Gadi V.P. Reddy, Lu Lv

Faculty Publications

Although many toxicological evaluations have been conducted for honey bees (Apis mellifera), most of these studies have only focused on the effects of individual chemicals. However, honey bees are usually exposed to pesticide mixtures under field conditions. In this study, we examined the effects of individual pesticides and mixtures of clothianidin (CLO) with eight other pesticides [carbaryl (CAR), thiodicarb (THI), chlorpyrifos (CHL), beta-cyfluthrin (BCY), gamma-cyhalothrin (GCY), tetraconazole (TET), spinosad (SPI) and indoxacarb (IND)] on honey bees using a feeding method. Toxicity tests of a 4-day exposure to individual pesticides revealed that CLO had the highest toxicity to A. mellifera, with …

Desire And The Work It Does: Alterity And Exogamy In A Kotiria Origin Myth From The Northwest Amazon Of Brazil, Janet M. Chernela

Tipití: Journal of the Society for the Anthropology of Lowland South America

In terms of the pan-Amazonian social paradigm that transforms affines into kin and assimilates them into the consanguineal unit, Eastern Tukanoans must be regarded as exceptional. This paper explores a foundation myth that allows us to better understand relations of self and Other, incest and exogamy, and violence and amity among the Eastern Tukanoan-speaking Kotiria. The narrative provides a heretofore-absent foundation for Tukanoan affinity, revealing complications and nuance in Kotiria notions of alterity and the generative role of Desire in its transformation. It is a synthesis not from nature, but from poesis; not from trust, but from theft; not from …

Recent Advances In Silver Nanoparticle-Based Electrochemical Sensors For Determining Organic Pollutants In Water, Ziad Khalifa, Moustafa Zahran, Magdy Zahran, Magdi Abdelazzem

Chemical Engineering

Water pollutants have attracted great attention because of their negative effect on human health. Accordingly, various analytical techniques have been investigated to detect water pollutants as a preliminary step for their control. This review highlights silver nanoparticles (AgNPs) as promising electrochemical probes studied for detecting organic pollutants. Electrochemical sensors can be fabricated by modifying electrode surfaces using AgNPs via different techniques, such as electrochemical deposition, drop casting, spin coating, sticking, and transfer sticking, as well as carbon paste-based modification. AgNPs at electrode surfaces can be identified by their stripping to form Ag+ with a particular oxidation peak. Additionally, they can …

Natterer In Neotropical Nematoda: Species Described By Rudolphi, Diesing, And Molin, Ricardo Guerrero

MANTER: Journal of Parasite Biodiversity

Between 1817 and 1835 Johann Natterer collected 1,729 samples of endoparasitic helminths in Brazil and southern Venezuela. Of the 323 names that were assigned to the collected nematode specimens, 163 are still valid and accepted species, 84 are still doubtful, and 76 must be rejected. In this work, each name is analyzed and correlated to the literature to clarify its taxonomic status.

The purpose of this review of the material collected by Natterer is to establish a complete list of all described species; their current status; and whether they are valid species, synonyms, or nomen nudum as well as to …

The Self-Directed Goal Theory Experiment: A Mixed Methods Study Of Personal Development Goal-Setting Programs And Self-Efficacy, Tara N. Strickland

Dissertations

Andragogy is not dead; it may be simply lying dormant until its essential component, self-directed learning, revives it again. The fact is that self-directed learning can be formal or informal. This mixed methods study explored the informal side of self-directed learning, concentrating on self-help (a popularized form of personal development goalsetting). Despite a thriving self-help market, several personal development goal-setting programs focus more on goal achievement, little on goal planning, and even less on the individual. A comparative analysis of autonomous, guided, and self-directed personal goal-setting programs determined if self-directedness maximizes self-efficacy. Additionally, the researcher’s original Self-Directed Goal Theory and …

Evaluating Soil Carbon As A Proxy For Erosion Risk In The Spatio-Temporal Complex Hydropower Catchment In Upper Pangani, Northern Tanzania, Aloyce I.M. Amasi, Maarten Wynants, Remigius A. Kawala, Shovi F. Sawe, William H. Blake, Kelvin M. Mtei

School of Geography, Earth and Environmental Sciences

Land use conversion is generally accompanied by large changes in soil organic carbon (SOC). SOC influences soil erodibility through its broad control on aggregate stability, soil structure and infiltration capacity. However, soil erodibility is also influenced by soil properties, clay mineralogy and other human activities. This study aimed to evaluate soil organic carbon as proxy of soil erosion risk in the Nyumba ya Mungu (NYM) catchment in Northern Tanzania. Soil organic carbon (SOC) was measured by an AgroCares scanner from which the soil organic matter (SOM) was derived using the conversional van Bemmelen factor of 1.72. A regression analysis performed …

Covid-19-Associated Pulmonary Aspergillosis: A Case Report From The Covid-19 Surveillance Program., Mohamad Belal Aldaas, Dylan Goldsmith, Forest W. Arnold

The University of Louisville Journal of Respiratory Infections

A 72-year-old male was brought to the hospital following a motorcycle crash and was admitted for multiple trauma management. His initial course of hospitalization was complicated by mild hypoxemia and altered mental status. Respiratory workup and imaging were consistent with SARS-CoV-2 pneumonia. He completed a five-day course of remdesivir and a ten-day course of dexamethasone. Twenty days later, he developed a low-grade fever. His chest computerized tomography (CT) showed gas and fluid containing parenchymal collection in the anteromedial right middle lobe measuring up to 4.8 cm, most consistent with a pulmonary abscess. Antimicrobial treatment was started.
