Exploring Border Rhetoric, Resistance, And The American Dream: Alexandria Ocasio-Cortez' First House Address, Candice L. Ruh Phd, Cassandra Hightower

Feminist Pedagogy

Border rhetoric can be a “muddy” topic for undergraduates, as borders are often taught as fixed, factual lines that divide places and people. However, from a communication perspective, borders are fluid, symbolic, and socially constructed. This difference between viewing borders as physical dividers versus rhetorical constructs creates a valuable opportunity for students to think critically about how meaning is shaped by borders of land, language, and identity.             This original teaching activity uses Representative Alexandria Ocasio-Cortez’ (D-NY) first House speech—the most-watched C-SPAN video within 12 hours of release (Gajanan, 2019)—as a central case. It invites students to analyze a key moment …

Chronicling Oral History In The Classroom: Preserving Campus Memories And Fostering Connectivity, Madison A. Krall, Kate Sierra

Feminist Pedagogy

In our ever-changing world, projects involving undergraduates, faculty, and staff serve a dual purpose. This oral history assignment aids students in developing the real-world skills of project management, interpersonal communication, interviewing, and digital literacy. We outline how student-created oral histories reflect the underpinnings of feminist pedagogy and contribute to campus connectivity as students learn how people from different intersectional backgrounds can collaborate to benefit their university communities. Using communication research methods and new-age technology, students capture memories of long-standing campus representatives and develop video products for their university archives that bridge past university life, today’s classroom skills, and tomorrow’s potential.

Timing Isn’T Everything: Rethinking The Intersection Of Virginia Standing Doctrine, Bankruptcy Law, And Virginia’S Statute Of Limitations Applicable To Personal Injury Causes Of Action, Joshua B. Davis

Liberty University Law Review

This Article posits that the interaction between Virginia standing doctrine, bankruptcy law, and Virginia’s two-year statute of limitations applicable to personal injury causes of action creates a timing issue that can lead to harsh and unnecessary consequences for certain plaintiffs. Under the Supreme Court of Virginia’s decisions in Kocher v. Campbell and Eye Consultants of Northern Virginia, P.C. v. Shaw-McDonald, the continued viability of a plaintiff’s personal injury cause of action can depend entirely on whether the plaintiff—who mistakenly fails to properly claim the personal injury claim as exempt on the bankruptcy schedules—files for bankruptcy before or after filing …

Impact On Energy Budgets In Grassland Production And Conservation Of Possible Production Of Energy From Biomass Crops, R J. Wilkins

IGC Proceedings (1977-2023)

There is commonly a conflict between output/unit of area of land and output/unit of support-energy (SE) input. The possibil­ity of using a proportion of the total land area for biomass energy production suggests an approach for calculating grassland out­put/ha unconfounded with differences in SE input. Output can be calculated for an area of land that is devoted to grassland and biomass energy crops in proportions that result in a net demand for SE of zero. Outputs of utilized metabolizable energy (UME) are related to inputs of SE for (1) grazed grass with high application of nitrogen (N) fertilizer and (2) …

Efficiency Of Dairying Under Contrasting Feeding And Management Systems In North America, Israel, Europe, And New Zealand, J.D. J. Scott

IGC Proceedings (1977-2023)

Four different systems of feeding and managing dairy cattle are seen in major milk-producing countries. These are (1) feeding purchased roughages and concentrates to zero-grazed, intensively penned cows; (2) home growing of roughages and most con­centrates for zero-grazed animals; (3) feeding concentrates with conserved pasture and other roughages in winter and reduced concentrates to grazed cattle in spring-summer; and (4) feeding cattle on grazed pasture and conserved pasture throughout the year. The following data on the four systems were obtained from examples in southern California, Wisconsin, England/Wales, and New Zealand. Average fat-corrected milk (FCM)/cow is approximately 7,140, 5,300, 4,670, and …

Potential Contribution Of White Clover To The Economics And Support-Energy Inputs Of Grass-Based Beef-Production Systems, T A. Stewart, R E. Haycock, A S. Laidlaw

IGC Proceedings (1977-2023)

Biological output, gross margins, and efficiency of support-energy usage in an 18-month beef-production system on grass-white clover swards receiving either 50 kg N/ha stocked at 3.3 head/ha (low N) or 300 kg N/ha stocked 4.5 head/ha (high N) were compared. To date, two production cycles (1977-1979 and 1978-1980) at two sites have been completed. Mean live-weight and carcass gains/ha were, respectively, 17.5% and 14% higher from the high-N than from the low-N system. Gross margin/head was higher from the high-N system in the first production cycle but not in the second. In the low-N system as com· pared with the …

An Evaluation Of The Black Walnut- Tall Fescue Pasture-Management System, H E. Garrett, W B. Kurtz

IGC Proceedings (1977-2023)

The economic and biological feasibility. of a black walnut-livestock-grazing multicropping-management regime bas been evaluated for comparison with a similar livestock-management regime conducted in the open. Pure tall fescue plots were established under open and black walnut-shade conditions. Forage yields on a dry-weight basis were estimated for a 3-year period. A concurrent grazing trial was co􀀌ducted on similar sites using 1.2-ha plots. Black walnut seedlings were planted within the plots on a 3 x 12-m spacing and protected from grazing animals by electric fencing. The economic analyses of the alternate grazing systems were based on their respective present net worth and …

Economic Analysis Of The Impact Of Management Decisions On Production And Use Of Silage For A Dairy Enterprise, A J. Corrall, H D. St. C Neal, I M. Wilkinson

IGC Proceedings (1977-2023)

The aim of this work was to examine the influence of variations in grass management and methods of ensiling on the economics of milk production for autumn-calving cows. A simulation model was developed to combine knowledge of plant and animal responses and their interactions in order to calculate the effects of management options on economic balances. Input data were compiled for herbage production from cut­ting strategies that gave herbage at four digestibilities, at two levels of applied nitrogen, and in three climates. Experimental evidence was also collated to construct matrices of loss of dry matter and changes in digestibility and …

Effective Training For International Students, G W. Thomas

IGC Proceedings (1977-2023)

The observations made in this paper are based upon contacts with international students, both in the U.S. and in many other countries. Two of the most serious problems in increasing world food production in the developing world are (1) lack of trained people, and (2) technology transfer. A third constraint, inadequate research, is also critical but not of the magnitude of the other two, since there is a great amount of research information available that is not being adequately ut:ilized. Training needs fall into two general categories in which deficiencies are obvious: (1) graduate-level programs, particularly in the applied fields …

West Virginia University Allegheny Highlands Project: A Ten-Year Experiment In Technology Transfer, B S. Baker, P E. Lewis, E K. Inskeep, R H. Maxwell

IGC Proceedings (1977-2023)

West Virginia's livestock industry is characterized by relatively small units located predominantly on rough terrain not suited to highly mechanized or intensive agriculture. As a result of changes in West Virginia agriculture during the last 40 years, there has been a reduction in support from agribusiness, marketing alternatives, and profitability. Some agriculturalists contend that if present technology were adopted, beef and sheep farms in mountainous regions could be profitable and could contribute to the local economy. The objective of the Allegheny Highlands Project (AHP) was to test the effectiveness of a method for delivering technological information to farmers to promote …

Grassland Societies In Manitoba, G Bonnefoy

IGC Proceedings (1977-2023)

Farmers with forage and livestock problems were organized into grassland societies and cooperated with extension staff sup­plied by 􀀇anitoba Agriculture. The purpose of the grassland societies is to improve by demonstration the traditional manage­ment practices used by livestock producers for pastures and forage production for beef and dairy herds. Results over 5 years were clearly positive. Significant improvements were noted in both field and animal husbandry practices. The experience confirmed the principles of the diffusion-adoption process and its application to adult extension education.

Pasture Demonstrations For Beef: Agronomic Considerations, N P. Martin, P R. Hasbargen, R L. Arthaud, G J. Sullivan

IGC Proceedings (1977-2023)

Beef cattle supply a major portion of farm income of northern Minnesota, but the major resource supporting this enterprise, forage, is vastly underutilized. A 5-year on-the-farm demonstration was conducted by the Agricultural Extension Service of the University of Minnesota and the Upper Great Lakes Regional Commission to improve income in this area by improving man­agement of the beef enterprise.

We compared one or two improved pasture systems with an unimproved permanent grass pasture composed predominantly of Kentucky bluegrass (Poa pratensis L.), system A, on each of six ranches. Improved systems included use of a cool-season grass fertilized with 138 kg …

Optimizing The Use Of Grazed Dryland Pasture In Western Oregon, T E. Bedell

IGC Proceedings (1977-2023)

When they are properly fertilized, western Oregon dryland pastures of subterranean dover with grasses such as perennial rp:g:rass, tall fescue, and resident annuals produce total annual dry-matter yields averaging 6,500 kg/ha. Some sites are capable of over 9,000 kg/ha. Optimum use of this forage is complicated by its highly seasonal availability. Over 50 % of the total growth occurs from late April to mid-June. Only about 10% takes place during autumn-early winter, and virtually none occurs during summer. Research shows livestock weight gains from 300 to over 700 kg/ha can be expected depending upon pasture mixture and kind of grazing …

Growing Beef Cattle On Native Pasture Oversown With The Legume Fine-Stem Stylo In Subtropical Australia, K G. Rickert, G M. Mckeon, J H. Prinsen

IGC Proceedings (1977-2023)

Fine-stem stylo (FSS), Stylosanthes guianensis var. lntermedia, is a perennial legume suitable for sowing into native Heteropogon contortus pastures on well-drained soils in southeastern Queensland. A grazing system is described that aims to maintain a productive FSS pasture and grow steers to 480 kg live weight at 27 months of age. This goal requires gains of 300 kg/steer in 20 months after weaning. Results from a short-term field study of the system were analyzed for long-term repeatabil­ity using a simple model that predicted animal production from stocking rate and weather records. The system was studied near Gayndah, Queensland, on 11.3 …

Development Of Legume-Based Pastures For Beef Production In Dry Tropical Areas Of Northern Australia, J G. Mcivor, R J. Jones, C J. Gardener, W H. Winter

IGC Proceedings (1977-2023)

A program designed to select pasture legume species suitable for beef cattle grazing in the 500-1,500 mm annual rainfall zone of northern Australia is described. A detailed study of members of the genus Stylosanthes, involving spaced-plant studies and small-scale cutting trials at a number of sites, identified a number of persistent, high-yielding accessions. Animal-production studies have shown that the introduction of a legume into native pasture generally results in an increase in carrying capacity, although production/head may not increase unless superphosphate is applied. The Stylosanthes accessions can produce moderate to high yields without superphosphate, and only small applications of superphosphate …

Development Of A Pasture Research Program For The Tropical Savanna Region Of Brazil, D Thomas, C P. Moore, W Couto, R P. De Andrade, C.M C. Da Rocha, D T. Gomes

IGC Proceedings (1977-2023)

The tropical savannas (cerrados) of west central Brazil contain almost 40% of the nation's cattle population. However, the low productivity and nutritive value of the native pastures is a serious limitation to cattle production. To improve the nutrition of the grazing animal, a research program has been developed with emphasis on the integrated use of cultivated pastures. The program aims (1) to select species adapted to the cerrados, (2) to determine their nutrient requirements, and (3) to develop methods of establishment and utilization. The program is being conducted at the Cerrados Agricultural Research Center (CP AC) at lat 15°S. Rainfall …

Advances In Pasture Research And Development In Santa Cruz, Bolivia, R T. Paterson, C R. Horrell

IGC Proceedings (1977-2023)

Cattle production is important in Santa Cruz but is low in productivity, due in part to low grazing value of natural pastures, particularly in the dry season. Other constraints to cattle production include low land values, poor management, high cost of in­puts, and relatively low product prices. This program is aimed at providing higher-quality, low-cost pastures for complemen­tary use within traditional grazing systems. Improved introduced species were identified for five agro-ecological zones, and commercial seed production of the following was encouraged: Petri guineagrass (Panicum maximum), Brachiaria decumbens, buf­felgrass (Cenchrus ciliaris), glycine (Neonotonia wightii, formerly Grycine wightii), Archer axillaris (Macroryloma axillare), …

Pasture Research Results In The Brazilian Amazon, E.A S. Serrao

IGC Proceedings (1977-2023)

Natural upland savanna grasslands are represented mainly by well-drained savannas, with the cerrado type predominant, and by poorly drained savannas with the campo alto-type being the most common. The main limitations are low forage­production potential and, especially, low forage quality. About 3 million ha of rain forest has been replaced by improved pastures of guineagrass (Panicum maximum, 80% ), jaraguagrass (Hyparrhenia rufa, 10% ), and Brachiaria spp. and other grasses (10% ). During the first few years after establish­ment, pastures are productive. However, with time, a gradual decline of productivity occurs, especially in P. maximum pastures. About 0.5 million ha …

Pasture Research Project In The Brazilian Amazon, H M. Saito, H W. Koster, E.J A. Khan, D F. Winslow, A M. Hollick, P M. Paollichi, A C. Costa, F A. Rolim

IGC Proceedings (1977-2023)

The procedure for pasture establishment in the Brazilian Amazon has been to cut down and burn forest and then to seed guineagrass (Panicum maximum L.). Under normal management, animal production has dropped significantly as pastures have deteriorated and have been invaded by weeds. A dearth of knowledge of climate, soils, and plant species; the manner in which pastures have been planted and managed; and a complete absence of fertilization have led to overgrazing and complete degrada­tion of the pastures. This study was undertaken to identify soil problems, adapted forage species, pasture-management practices, and ways of regenerating pastures. Two regions …

Animal Production From Brazilian Tropical Pastures, G L. Rocha, V.B G. Alcantara, P B. Alcantara

IGC Proceedings (1977-2023)

This review deals with the potential for beef production from nitrogen- and legume-based pastures in tropical Brazil. Possibilities for impr􀀞ving the beef industry supported by grass-legume pastures are very promising. According to the literature examined, legume-based pastures produced an annual average of 329 kg gain/ha, and nitrogen (N) fertilization resulted in 4.56 kg gain/ha. Phosphorus (P) was the main fertilizer utilized in addition to N, followed by potassium (K), lime, and micronutrients. An­nual rainfall averaged 1430 mm. Grasses used were of the genera Melinis, Hyparrhenia, Panicum, Cenchrus, Digitaria, Cynodon, Brachiaria, and Pennisetum, and the legumes were of the genera Macroptilium, …

Hemarthria Altissima: A Pasture Grass For The Tropics, K H. Quesenberry, W R. Ocumpaugh, O C. Ruelke

IGC Proceedings (1977-2023)

Limpograss (Hemarthria altissima [Poir] Stapf. et C.E. Hubb), introduced into the U.S. in 1964, has been evaluated for use as a pasture grass. Under Florida conditions it has shown yield potential equal to or greater than other tropical pasture grasses. The cultivar Bigalta has higher in-vitro organic-matter digestion (IVOMD) than other tropical grasses at comparable growth stages. Early evaluations of limpograss involved only three clones, but additional genotypes were collected and introduced during the late 1960s and early 1970s, and an evaluation scheme for this germ plasm was undertaken. Our objectives were to evaluate rapidly the available germ plasm of …

Discursive Analysis Of Authoritarian Islamist Populism: The Case Of The Justice And Development Party (Morocco), Youssef Aboudi

Al-Kīmiyā

This article analyzes the linguistic modalities constitutive of political populism, with particular attention to its contemporary authoritarian-leaning manifestations. Conceived as a discursive construction or a style of communication (Taguieff, 1997), populist discourse is organized around a charismatic figure who claims a direct relationship with an idealized people, set in opposition to an elite deemed illegitimate and inherently malevolent (Breton, 2009). The study advances the hypothesis that the staging of charismatic power, grounded primarily in conspiratorial logics that generate an atmosphere of insecurity and fear (Wodak, 2015), contributes to reinforcing mechanisms of symbolic and political domination while inhibiting critical reflexivity (Weber, …

Queer, Hybrid Participatory Design: Relational Practices And Norms For Coalition Building With Rural, Lgbtq+ Communities, Luettamae Lawrence, Maureen Boyle, Chasity Mayo, Catherine A. Rushworth, Moira Anderson, Dorothy Wallis, Jayme Walters

Instructional Technology and Learning Sciences Faculty Publications

This paper examines the first year of collaboration between the Bear River Region LGBTQ+ Community Coalition and queer residents in rural northern Utah, United States, using a hybrid participatory design (PD) approach. Using Yep’s queer relationality theory, we examine how hybrid spaces were designed and iteratively adapted to support inclusion, care, and collective agency among LGBTQ+ community members. Drawing on Community Coalition Action Theory and queer PD, we analyze four cases from May 2024 to June 2025 including workshops and regular meetings to explore how relational practices evolved across different formats and phases of coalition development. In this paper, we …

In That Space, We Were Communis, Eliana Namen

be Still

In reflecting on my understanding of community, there were many moments I could have chosen to write about. Yet the memory of my grandmother’s death remains the one most deeply etched in me. When I began considering what community truly meant in my own life, I found myself returning to that room. In her illness and eventual passing, she drew together an extraordinary constellation of people: family, friends, neighbors, whose lives she had quietly shaped. Her life created ripples far beyond what any one person could see. In witnessing that gathering, I came to understand community not merely as shared …

Hiv-1 Tat-Driven Glutamate Dysregulation: Implications For Cognitive Impairment In Hand, Brenna Duffy, Michael Nonnemacher, Sandhya Kortagere

Kimmel Cancer Center Faculty Papers

PURPOSE OF REVIEW: HIV-1-associated neurocognitive disorders (HAND) manifest in 15% to 50% of people with HIV, impairing learning and memory and executive function. The chronic generation of HIV-1 Transactivator of transcription (Tat) likely contributes to HAND via direct neuronal toxicity and glial-mediated toxicity. This review summarizes our current understanding of how chronic Tat generation from microglia and astrocytes promote glutamate excitotoxicity.

RECENT FINDINGS: In recent years, the indirect effects of Tat through the activation of glial cells have gained significant interest. This review highlights microglia and astrocytes as HIV-1 reservoirs that release Tat protein in the central nervous system. Specific …

Case Study On Operational Performance Improvement By Turbocharger Nozzle-Ring Modification In Shipboard Generators, Jong-Hun Im, Mukyeong Kang, Sang-Deuk Lee

Journal of Marine Science and Technology–Taiwan

Owing to increasingly stringent emission regulations imposed by the International Maritime Organization and rising fuel prices, the demand for enhanced energy efficiency and emission control in marine power systems is increasing. This study presents a case study in which the performance of an aging auxiliary generator is restored by modifying the turbocharger nozzle ring. The vessel, a 12-year-old crude-oil tanker, experienced repeated operational issues with its No. 3 generator. This included elevated exhaust gas temperatures, reduced intake air pressure, and frequent turbocharger surges. To address these challenges, the nozzle-ring blade angle was reduced by approximately 2° using spare components, while …

Towards Sustainable Marine Education: Assessing High School Students’ Understanding Of Conservation Concepts, Cheng-Chieh Chang, Tsuyoshi Sasaki, Ya-Yin Liao, Ling-Ya Hung, Liang-Ting Tsai

Journal of Marine Science and Technology–Taiwan

This study assesses the concepts of marine resource conservation and sustainability among Taiwanese high school students by developing a Chinese version of the Marine Resources Conservation and Sustainability Scale. Grounded in the cognitive, socio-emotional, and behavioral learning objectives outlined in UNESCO’s Education for Sustainable Development Goals (ESDGs), the scale targets students aged 16 to 18 to examine gender differences in marine knowledge and conservation concepts. The scale comprises 31 items across four dimensions: the first section evaluates marine knowledge, while the remaining dimensions utilize a four-point Likert scale to assess cognitive, socio-emotional, and behavioral learning objectives, respectively. The results indicate …

Dynamic Governance Of Transboundary Fisheries Through Deep Learning And High-Frequency Vessel Tracking Data For Climate-Resilient Management: An Application To The East China Sea, Qin Lin, Yaqing Shu, Manel Grifoll, Hongxiang Feng

Journal of Marine Science and Technology–Taiwan

Transboundary fisheries governance is increasingly challenged by jurisdictional conflicts, regulatory asymmetries, and climate-induced stock shifts in fish stocks, especially in contested regions like the East China Sea (ECS). This study capitalizes on China’s high-frequency BeiDou Navigation Satellite System (BDS) data (June 2021–May 2022) to pioneer a CNN-BiLSTM deep learning model to dynamically identify fishing hotspots and evaluate policy effectiveness. By integrating vessel trajectories, environmental variables, and regulatory events, we examine spatiotemporal patterns of fishing effort relative to seasonal bans, extreme weather, and quota systems. Key findings reveal: (1) post-moratorium (September–December) concentration of fishing intensity, peaking in November; (2) significant weather-driven …
