Use Of Old Order Anabaptist-Produced Publications To Develop An Injury Surveillance System For Old Order Populations, Paul Jones, William Field, Donald Kraybill, Stephen Scott

Journal of Amish and Plain Anabaptist Studies

To achieve a clearer picture of injuries within Old Order Anabaptist communities, Purdue University’s Agricultural Safety and Health Program collaborated with the Young Center for Anabaptist and Pietist Studies at Elizabethtown College to conduct a pilot study on this topic. The team developed an injury surveillance system based not on traditional injury data sources and instruments but on data provided in Old Order-produced publications, specifically The Budget, Die Botschaft, and The Diary. While traditional surveillance methods have generally yielded injury data on less than 30 Old Order cases per year, the Old Order Injury Database, developed through the Purdue/Young Center …

Modeling Of Energy Consumption Of Cucumber Greenhouses Usingartificial Neural Network And Anfis, Zahra Ebrahimpour, Vali Sharabiani, Ebrahim Taghinezhad

Emirates Journal for Engineering Research

Optimal use of energy is a key requirement for sustainable agriculture. However, the growing demand for food has increased the energy consumption of the agricultural sector. Since the agricultural sector is the main sector of energy conversion, we focused on evaluating the efficiency of cucumber greenhouses in East Azerbaijan Province by artificial neural network and ANFIS. So, 135 cucumber producing greenhouses were sampled, and data were collected with an interview questionnaire. Finally, the inputs and output energy, the energy indices and the energy consumption of cucumber greenhouse was assessed and modeled. Among the inputs, fuel and seed had the highest …

Accounting Assumptions And The Farm Business, Timothy Meyer

Cornhusker Economics

Farmers in Nebraska and the surrounding area have been slow to adopt accrual accounting methods. This is no surprise; the alternative, cash accounting, is simple, provides a real-time analysis of the cash position of the firm, and works well with income tax preparation. However, cash accounting has no methodology for the special timing of agricultural production or specific processes to evaluate profitability, liquidity, or solvency. Accrual accounting, GAAP (Generally Accepted Accounting Principles), and finally the FFSC (Farm Financial Standards Council) rectify these shortcomings. Adoption of GAAP, and subsequently the FFSC “tweaks” will allow farmers and ranchers in Nebraska to make …

Application Of Autofluorescence For Confocal Microscopy To Aid In Archaeoparasitological Analyses, Johnica Jo Morrow, Christian Elowsky

Department of Agronomy and Horticulture: Faculty Publications

Confocal laser scanning microscopy (CLSM) was used to examine archaeoparasitological specimens from coprolites associated with La Cueva de los Muertos Chiquitos (CMC) located near present-day Durango, Mexico. The eggs for 4 different types of parasites recovered from CMC coprolites were imaged using CLSM to assist with identification efforts. While some of the parasite eggs recovered from CMC coprolites were readily identified using standard light microscopy (LM), CLSM provided useful data for more challenging identifications by highlighting subtle morphological features and enhancing visualization of parasite egg anatomy. While other advanced microscopy techniques, such as scanning electron microscopy (SEM), may also detect …

Spread Of Domestic Animals Across Neolithic Western Anatolia: New Stable Isotope Evidence From Ugurlu Höyük, The Island Of Gökçeada, Turkey, Suzanne E. Pilaar Birch, Levent Atici, Burcin Erdogu

Anthropology Faculty Research

The origins of agriculture in Southwest Asia over 10,000 years ago and its subsequent spread into Europe during the Neolithic have been the focus of much archaeological research over the past several decades. Increasingly more sophisticated analytical techniques have allowed for better understanding of the complex interactions that occurred amongst humans, animals, and their environments during this transition. The Aegean Islands are critically situated where Anatolia and the mainland Greece meet, making the region pivotal for understanding the movement of the Neolithic into Europe. Located on the largest Turkish Aegean island of Gökçeada, the site of Uğurlu Höyük dates to …

Maryland Nutrient Management Policies, J. David Aiken

Cornhusker Economics

Nonpoint pollution control. The federal Clean Water Act (CWA) regulates point sources of water pollution (such as municipal and industrial wastewater discharges to river and streams) but not nonpoint sources (NPSs), like farm runoff. EPA has provided financial incentives to states to develop and implement NPS programs but does not regulate NPSs itself. Clean water groups have sued to force states to implement wasteload allocation under the CWA on streams not meeting water quality requirements and to require cities and idustries to clean up their wastewater discharges to improve water quality. States can elect to regulate NPSs under this total …

Molecular Phylogeny Implemented In An Introductory Plant Classification Course, Chao Cai, Jo Ann Banks

Libraries Faculty and Staff Presentations

Plant classification is one of the core components in undergraduate programs related to plant sciences. Traditionally plant classification courses primarily introduce morphology-based taxonomy because of practical needs in the field. However, the publication of new plant classification systems by Angiosperm Phylogeny Group (APG) using molecular phylogeny methods leads to the trends of using molecular evidence (DNA barcode) for plant identification. In our introductory plant classification course, we included a two-week module (lectures and labs) to introduce key concepts and fundamental skills in molecular phylogeny. Week 1 included concepts of evolutionary tree thinking, data mining in NCBI using BLAST search, and …

Biosecurity Research Articles

BACKGROUND

Powdery mildew caused by Blumeria graminis f. sp. hordei (Bgh) is a constant threat to barley production but is generally well controlled through combinations of host genetics and fungicides. An epidemic of barley powdery mildew was observed from 2007 to 2013 in the West Australian grain belt.

RESULTS

We collected isolates across Australia, examined their sensitivity to demethylation inhibitor (DMI) fungicides and sequenced the Cyp51B target gene. Five amino acid substitutions were found, of which four were novel. The most resistant haplotypes increased in prevalence from 0% in 2009 to 16% in 2010 and 90% in 2011. …

Movement Ecology Of Eastern Wild Turkeys (Meleagris Gallopavo Silvestris) And Turkey Hunters On Public Land In South Carolina, Usa, Alaina Pamela Gerrits

LSU Master's Theses

Wild turkeys (Meleagris gallapavo, hereafter turkey) are the second most pursued big game species in the United States. Turkey hunting occurs primarily during spring, and on publicly-owned lands managers monitor hunter numbers and harvest to adjust hunter opportunity. Contemporary research has shown a decline in productivity and harvest of turkeys in the Eastern United States. Studies have also found that hunting activity on public lands can influence male turkey behavior, hence research detailing hunter behaviors and hunter-wild turkey interactions is needed to better inform management activities. We found turkey hunters exhibited both stationary and active behaviors while hunting …

Wwoofing In Northern Europe: A Cross-Cultural Examination Of Food, Farming, And Community, Seth Brawner

Annual Student Research Poster Session

Industrial agriculture has changed the way Americans eat food. More food is available but many eat without knowing where the food came from, or the additives that were used to grow and preserve it. The implementation of this large-scale food system has caused many health issues among the American population. Large-scale agriculture systems, being primarily monocultures, are also the cause of many environmental problems affecting the United States such as deforestation, soil erosion, and the eutrophication of waterways. Small-scale, organic agriculture has the potential to combat these environmental issues while restoring local, more transparent food systems. This summer I spent …

Plant-Produced Oxidation/Reduction Enzymes As Bioremediation Agents, Joshua Byrd

Student Theses and Dissertations

Contamination of the environment directly impacts animal, plant, and human health and agricultural production. A potential solution this project is offering incorporates the use of enzymes from fungi; manganese peroxidase and laccase. Two formulations of recombinant manganese peroxidase (MnP) from corn and commercial laccase have been tested on synthetic dyes and atrazine in an aqueous environment. Laccase utilizes oxygen when degrading these pollutants. All dyes were degraded to some extent by both enzymes. The products from the enzymatic reactions of one dye, Methyl Orange were analyzed with High Performance Liquid Chromatography (HPLC). The HPLC showed that there were products of …

Does Targeting Healthy Food Labels To Populations At High Risk Of Diet-Related Diseases Increase Label Effectiveness?, Christopher Gustafson

Cornhusker Economics

The decades-long increase in obesity in the U.S. has inspired multiple policies aiming to improve individuals’ food choices, which play an important role in diet-related diseases. Early policies—which have continued to be implemented and refined—took the view that providing consumers with information would give them the tools needed to choose a healthy diet. Both nutrition facts panels, which are provided on the side or back of nearly all packaged food products in the U.S, and calorie labeling in restaurant chains with 20 or more locations seek to address a lack of information among consumers.

While nutrition information is a necessary …

Development Of An Autonomous Aerial Toolset For Agricultural Applications, Terrance Life

Mahurin Honors College Capstone Experience/Thesis Projects

According to the United Nations, the world population is expected to grow from its current 7 billion to 9.7 billion by the year 2050. During this time, global food demand is also expected to increase by between 59% and 98% due to the population increase, accompanied by an increasing demand for protein due to a rising standard of living throughout developing countries. [1] Meeting this increase in required food production using present agricultural practices would necessitate a similar increase in farmland; a resource which does not exist in abundance. Therefore, in order to meet growing food demands, new methods will …

Chronic Kidney Disease From Non-Traditional Causes Throughout Central America, Abigail K. Watson

Senior Theses

Throughout many Central American countries, incidence of chronic kidney disease (CKD) has been on the rise. The disease mainly affects agricultural workers and differs from typical CKD. Patients in these countries often do not have preexisting conditions such as diabetes or hypertension known to be traditional causes of CKD. They also experience increased damage to the kidney tubules, rather than the glomeruli generally more heavily impacted. There has been speculation regarding the causes of CKDnT (chronic kidney disease of nontraditional causes), but no consensus has been reached. Two major hypotheses to explain the high prevalence among Central American sugarcane workers …

Swagriculture: A Qualitative Examination Of Women’S Participation In Samoa’S Agriculture Industry As Farmers And Growers, Charlotte Crandall

Independent Study Project (ISP) Collection

This study is an examination of how women participate in agriculture in Samoa as farmers and growers, what hardships women encounter and how they overcome these, and the organizations that influence people’s experiences. Censuses have historically undercounted the number of women in agriculture in developing countries, largely due to rigid international definitions of what counts as labor, which overlook cultural nuances, and this study aims to fill this gap in research. Data was collected through nine Talanoa-inspired interviews with women involved with farming or growing in Samoa, and overarching themes were analyzed. The themes have been grouped by the specific …

H-2a Temporary Agricultural Workers On Small Farms: Case Study Observations And Lessons Learned, Barrett Vaughan, Lerosha Ford, Silvia Brashier, Miles Robinson

Professional Agricultural Workers Journal

Abstract

The experiences of two small farmers in their efforts to employ and retain temporary agricultural workers through the H-2A Program were documented through an illustrative case study. Interviews of the farmers were conducted regarding the measures that they had to take in preparing for, employing, housing, hosting, managing, and financing the workers. These temporary agricultural workers were sought in support of these farmers’ continued participation in an initiative to assist small and limited-resource farmers in supplying produce to a major retailer. It was concluded that there are at least four priority areas for employing H-2A workers: planning, applying, maintaining …

Importance Of Tree-And Species-Level Interactions With Wildfire, Climate, And Soils In Interior Alaska: Implications For Forest Change Under A Warming Climate, Adrianna C. Foster, Amanda H. Armstrong, Jacquelyn K. Shuman, Herman H. Shugart, Brendan M. Rogers, Michelle C. Mack, Scott J. Goetz, K. Jon Ranson

Aspen Bibliography

The boreal zone of Alaska is dominated by interactions between disturbances, vegetation, and soils. These interactions are likely to change in the future through increasing permafrost thaw, more frequent and intense wildfires, and vegetation change from drought and competition. We utilize an individual tree-based vegetation model, the University of Virginia Forest Model Enhanced (UVAFME), to estimate current and future forest conditions across sites within interior Alaska. We updated UVAFME for application within interior Alaska, including improved simulation of permafrost dynamics, litter decay, nutrient dynamics, fire mortality, and postfire regrowth. Following these updates, UVAFME output on species-specific biomass and stem density …
