Effects Of Photopollution On Circadian Activity Rhythms, Aaron Schimer, Ting Liu, Elyse A. Bolterstein, Seth Magle, Caleb Gallemore, Elisabeth Dinello

Faculty Research and Creative Activities Symposium

Many aspects of organismal behavior and metabolism are modulated by biological clocks that oscillate with 24-hour (circadian) rhythms. These circadian clocks synchronize to environmental cues, such as cycles of light and dark, and allow organisms to anticipate changing environmental conditions and make use of temporal niches. The circadian clocks’ function, as well as the biological processes they modulate, can be altered by excess artificial lighting (photopollution). Photopollution levels in Chicago are some of the highest in the world, making it an ideal location to investigate the ecological and health impacts of nighttime light. While photopollution’s effects on specific species (e.g. …

Sport, Representation And Culture In The Modern World, 1920-2020, Steven A. Riess

Faculty Research and Creative Activities Symposium

Cultural historians study the change of human civilization over time. They focus on people’s beliefs, rituals, ideas, identity, social norms, institutions, and materials, with particular attention to the meanings of that culture’s elements (Hutton 1981). Cultural historians before World War II focused on high culture, but thereafter, because of the influence of cultural anthropology, they began to study popular culture, that include every day experiences and artifacts that express mass values and attitudes. Since the late 1960s, scholars have studied sport’s interaction with high and low culture, and also sport as an independent element of culture with s symbolic acts, …

Coloration And The Evolution Of Live Birth, Beth Reinke, Kirsty J. Macleod

Faculty Research and Creative Activities Symposium

Organisms have a finite amount of energy with which to invest in survival, growth, and reproduction. Reproductive strategies can range from those that require minimal energy to produce eggs (oviparity) that then develop unassisted, those that require some energy to produce eggs that then hatch internally (ovoviviparity), and those that require significant energy to fully develop internally before birth (viviparity). Females of species that invest large amounts of energy to give birth to live young (viviparous species) may thus have more to lose in choosing low-quality mates than females of species that lay eggs (oviparous species). These females may therefore …

Major Challenges Of Us Goat Producers And Way Forward, Tom Boyer

Professional Agricultural Workers Journal

Abstract

Three limiting resources to feed the world in the future are arable land, water, and Ag talent. Obviously, goat production is in this mix, because we need to use appropriate technology to improve goat production. Also, goat production is influenced by imports, markets, and a fragmented industry. Although imports may be good to fill in shortfalls in production, they may harm the industry due to their relatively lower prices compared to domestically produced goat meat. The markets are unstructured and generally lack accurate price discovery, which ultimately, makes pricing difficult. Furthermore, there have been the challenges of a fragmented …

Attention Restraint, Working Memory Capacity, And Mind Wandering: Do Emotional Valence Or Intentionality Matter?, Alexandra C. Nieto, Matthew S. Welhaf, Anum Mallick, Jonathan B. Banks

Faculty Proceedings, Presentations, Speeches and Lectures

Attention restraint appears to mediate the relationship between working memory capacity (WMC) and mind wandering (Kane et al., 2016). Prior work has identifed two dimensions of mind wandering—emotional valence and intentionality. However, less is known about how WMC and attention restraint correlate with these dimensions. Te current study examined the relationship between WMC, attention restraint, and mind wandering by emotional valence and intentionality. A confrmatory factor analysis demonstrated that WMC and attention restraint were strongly correlated, but only attention restraint was related to overall mind wandering, consistent with prior fndings. However, when examining the emotional valence of mind wandering, attention …

Service-Learning Research For Development: An Option For The Poor In Practice Through Social Analysis And Community Engagement, Thomas M. Kelly, Kate L. Nolt

Jesuit Higher Education: A Journal

A group of faculty, staff and students from Creighton University conducted a research project using a strengths-based approach to create a community health needs assessment (CNHA) in the fall of 2017. The instruments, including a survey to determine health status, a focus group questionnaire, an environmental scan and an individual interview instrument, were developed to help shift the paradigm from which many international medical missions are conducted with Creighton’s community partner in the Dominican Republic, the Centro de Educación para la Salud Integral (CESI). In the process of creating, developing, implementing, assessing and reformulating this strength-based CHNA, researchers encountered both …

Essays On Agricultural Water Pollution And Human Health, Na Lu

Economics ETDs

This dissertation mainly focuses on agricultural policies, water pollution and human health. Chapter.2 examines the causal impact of agricultural water pollution on individual health outcomes. The findings suggest that agricultural water pollution worsens health outcomes and these adverse health effects appear to be largely due to contaminated drinking water. Chapter.3 explores both of the intended wealth effect and unintended pollution effect on human health caused by China’s agricultural support polices. I find that although the income effect dominates on reducing the overall sickness, the pollution effect is more substantial on the diarrhea incidence and adult BMI. Income affects slightly higher …

Amaro E Piccante: The Production And Use Of Terroir In The Scandal Of Italian Extra Virgin Olive Oils, Daniel Gene Shattuck Ii

Anthropology ETDs

This dissertation explores the revalorization of Italian extra virgin olive oils after a food scare that revealed some oils to be inauthentic or adulterated. In the process of distinguishing products, producers and tasters looked toward terroir or the “taste of place” as proof of their declarations of authenticity and as a method for differentiating oils. However, in this attempt, they engaged with other pervasive tropes of difference including those that intersected with belonging, the local and global, and race. This dissertation argues that terroir is a material-semiotic object; that while it may be grounded in the materiality of oils is …

Seventeenth-Century Spanish Colonial Identity In New Mexico: A Study Of Identity Practices Through Material Culture, Caroline Marie Gabe

Anthropology ETDs

This dissertation explores how seventeenth-century Spanish colonial households expressed their group identity at a regional level in New Mexico. Through the material remains of daily practice and repetitive actions, identity markers tied to adornment, technological traditions, and culinary practices are compared between 14 assemblages to test four identity models. Seventeenth-century colonists were eating a combination of Old World domesticates and wild game on colonoware and majolica serving vessels, cooking using Indigenous pottery, grinding with Puebloan style tools, and conducting household scale production and prospecting. While assemblages are consistent in basic composition, variations are present tied to socioeconomic status. This blending …

Best Management Practices For Internal Parasite Control In Small Ruminants, Susan Schoenian, Enrique Nelson

Professional Agricultural Workers Journal

Abstract

Internal parasites represent a significant obstacle to a profitable and sustainable US goat industry. In some states, internal parasites are a year-round problem, while in others, they are a more seasonal challenge. Traditionally, parasite control methods relied heavily on antiparasitic drugs called anthelmintics or dewormers. Continued use and misuse of these drugs have resulted in increasingly resistant worm populations, necessitating more holistic or integrated methods of parasite control. A combination of practices will usually be necessary to achieve a satisfactory level of control. This paper discusses best management practices for controlling internal parasites in small ruminants, including pasture and …

Reproductive Technologies Used To Make Goats More Efficient, Seyedmehdi Mobini

Professional Agricultural Workers Journal

Abstract

With the introduction of Boer and Kiko breeds for meat goat production in the United States, more emphasis is being placed on the reproductive management to increase the number of offspring born and weaned and the frequency with which they are produced. It is also desirable to produce out of season kids to take advantage of a market premium for milk and meat. Reproductive manipulations, commercial Artificial Insemination (AI) programs using fresh or frozen semen, and Embryo Transfer (ET) have been developed and are in use most commonly in goats for reproductive efficiency.

Conservation And Management Of Salmon In The Age Of Genomics, Robin S. Waples, Kerry A. Naish, Craig R. Primmer

United States Department of Commerce: Staff Publications

Salmon were among the first nonmodel species for which systematic population genetic studies of natural populations were conducted, often to support management and conservation. The genomics revolution has improved our understanding of the evolutionary ecology of salmon in two major ways: (a) Large increases in the numbers of genetic markers (from dozens to 10⁴– 10⁶) provide greater power for traditional analyses, such as the delineation of population structure, hybridization, and population assignment, and (b) qualitatively new insights that were not possible with traditional genetic methods can be achieved by leveraging detailed information …

Assessment Of Particulate Matter Toxicity And Physicochemistry At The Claim 28 Uranium Mine Site In Blue Gap, Az, Jessica G.S. Begay

Biomedical Sciences ETDs

Particulate matter (PM) inhalation is known to have adverse effects on the respiratory and cardiovascular systems. Community concerns in the southwestern US have been expressed in regions of extensive open-pit hard-rock (especially uranium) mining that windblown dusts may pose an excess health risk. To address these concerns, we have undertaken a campaign to detail: (1) the amount and composition of the PM_2.5 in the region, (2) meteorological characteristics, such as wind speed and direction, and (3) and immunological and physiological responses of mice after PM_2.5 exposures.

For toxicity studies, C57BL/6 and apolipoprotein E-null (ApoE^-/-, a vascular …

Comparison Of Unused Water And Year-Old Used Water For Production Of Channel Catfish In The Biofloc Technology System, Bartholomew W. Green, Kevin K. Schrader, Steven D. Rawles, Carl D. Webster, Matthew E. Mcentire

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Since excreted feed nitrogen is bio-transformed efficiently in a fully functional mixotrophic biofloc technology production system, re-using this biofloc water over multiple production cycles should be beneficial. The present study, conducted in an outdoor biofloc technology production system, evaluated impacts on fish production characteristics and mineral status, common microbial off-flavors, and water quality dynamics for channel catfish (Ictalurus punctatus) reared in one-year-old waters with low or high total suspended solids used previously for two consecutive catfish biofloc studies or in unused (new) water. Total suspended solids were maintained at 300 to 400 mg/L in the unused and low …

Current Situation And Future Prospects Of The Us Goat Industry, Steve Hart, Roger Merkel, Terry Gipson

Professional Agricultural Workers Journal

Abstract

The current demand for goat meat in the US outstrips domestic supply. There is great potential for industry growth in the meat and dairy sectors. Whereas fiber prices have improved, loss of animals and market resources, labor costs for shearing, and lack of animal genetic resources prevent growth in the short term. As producers age, there is opportunity for new producers to enter the marketplace. Significant challenges exist, like access to local markets and abattoirs, dewormer resistant parasites, and feed costs. Establishing goat feedlots can increase meat supply and industry commercialization. Technologies used for cattle will be expanded for …

History Of The U.S. Goat Industry, Terry A. Gipson

Professional Agricultural Workers Journal

Abstract

Goats were first domesticated in the Fertile Crescent and then spread throughout the world. Goats were brought to North America into the southwestern U.S. in the 17^th century by early Spanish explorers and clergy. These goats are the ancestors of the Spanish goat of Texas and the Lamancha breed of California. English and other European settlers also brought their goats as they moved into the eastern U.S in the 18^th century. Angora goats were first imported in the U.S. in the mid-19^th century and the earliest importation of officially recognized dairy goat breeds occurred in the …

Goat Mortality Composting, Roger Merkel

Professional Agricultural Workers Journal

One lawful method to dispose of animal carcasses is composting. Mortality composting is a “green” method that provides the producer with valuable soil amendments. Composting sites should be away from water sources and public areas. Some states require a facility and/or permit for carcass composting so producers should contact their State Veterinarian. Animal composting generates little to no odor and generates temperatures high enough to kill pathogens. Mortality composting is an aerobic process and requires a proper C:N ratio achieved by using a high carbon source to envelop the carcass, moisture content of roughly 50%, and available oxygen. Common composting …

Optimizing Reproductive Performance In The Goat Herd, Dahlia O'Brien, Stephen Wildeus

Professional Agricultural Workers Journal

Abstract

Reproductive efficiency impacts pregnancy rates, kidding/lambing frequency and number of offspring available for market each year. To enhance reproductive performance, consider breed, selection, nutrition and health, and understand basic female and male reproduction. Proper ration formulation and feeding promotes reproductive function and leads to more offspring. Selecting the highest performing females while culling unproductive does increases reproductive rates. Diseases affect the reproduction and survival of kids, so adopting disease prevention strategies including routine vaccinations and deworming protocols that promote good herd health is necessary. Understanding male and female reproduction are critical in managing puberty, minimizing the effects of seasonality …
