Importance Of Considering Rate Of Passage When Determining Energy Content Of Forages For High Producing Animals, Dan J. Undersander, D. K. Combs, Edgard P. Beyer, Marcello T. Rodrigues

IGC Proceedings (1977-2023)

The objective of this study was to determine the effect of higher rates of passage and correspondingly lower rumen retention times on digestion of forages. One hundred and fifty samples of legumes, grasses and grass-legume mixtures were collected from farmer samples submitted to commercial forage testing laboratories and 32 samples of alfalfa at varying maturity were collected from research plots. In vitro digestions were performed for either 24 or 48 hours followed by neutral detergent analysis. Neither acid detergent fiber (ADF) nor neutral detergent fiber (NDF) predicted the standard 48-hour digestion very well (r² = -0.38 and B0.26, respectively). …

Nutritional Quality Of Digitaria Eriantha Steudel. Subsp. Eriantha Cv. Irene, M. J. L. Privitello, R. L. Sager

IGC Proceedings (1977-2023)

Digitaria eriantha is a South African perennial grass, C4 type, that grows during spring and summer with rainfalls higher than 400mm. The aim of this paper was to evaluate its nutritional quality profile: Crude Protein (%CP), True Protein (%TP), Soluble Protein (%SP), Non-Protein Nitrogen (%NPN), Neutral Detergent Fiber (%NDF) and Acid Detergent Fiber (%ADF) in cumulative production cuttings during a species cycle. In-sacco technique was applied to estimate the degradability of dry matter (DM). A simple regression statistics method was applied to relate different nutritional parameters. Digitaria eriantha presents low percentage of CP from flowering and of NPN during its …

Agronomic Potential And Nutritive Value Of Promising Leucaena Species In The Yucatan Peninsula, Luis Ramírez-Avilés, W. O. Cruz, Francisco J. Solorio-Sánchez

IGC Proceedings (1977-2023)

Two experiments were carried out in order to evaluate the agronomic potential, the nutritive value and the tolerance to psyllid (Heteropsilla cubana) of nine Leucaena species. A randomized block design with four repetitions was used. There were significant (P< 0.01) differences on dry matter production (i.e. leaf and twigs yield ). L. collinsii showed the most promising result, which could be related to its high psyllid tolerance. In a second experiment, the preference indices of Leucaena species was assessed with sixteen male pelibuey sheep in a cafeteria trial. There were significant (P< 0.0001) differences among Leucaena species. L. esculenta paniculata was the species most preferred . There was no relationship between chemical composition …

Experiencing Cinematic Vr: Where Theory And Practice Converge In The Tribeca Film Festival Cinema360, John V. Pavlik

Proceedings of the New York State Communication Association

Cinematic virtual reality (VR) production has reached enough capacity to support a festival. This paper offers a theoretical framework of VR narrative structure to critically examine one such festival in cinematic VR. The spotlight here is on the fifteen entries in the 2020 Tribeca Film Festival Cinema360. Findings suggest that although the field of cinematic VR has advanced substantially in recent years in terms of narrative design and user experience, there is still a considerable distance for VR storytellers to travel to fully utilize the nature and potential of the developing medium of virtual reality.

The Interplay Of Experience And Social Structure: Adaptation Through Media, Steven Hicks

Proceedings of the New York State Communication Association

In this investigation, I explore the tensions which self-referentially emerge within our constructed ‘nature’. I begin by exploring the origins of our contemporary media environment as discussed by McLuhan. I then interrogate the challenges of digital life through a close reading of the work of technology critic Giles Slade. I then conclude by situating these seemingly competing views of mediated existence within the framework of social systems theory. Through the lens of social systems theory, I reframe our contemporary technologies as adaptations to past challenges which also shape our experience of the potential choices and challenges of the future.

Putting The Social In Social Media: How Human Connection Triggers Engagement, Stephanie Adomavicius

Proceedings of the New York State Communication Association

Social media has become the preferred channel of information and has altered patterns of interaction and connection. As a result, society now revolves around a two-way form of communication with constant dialogue and instant responses. Public relations practitioners have had to adapt and change their strategy in order to keep up with the times, and because of this, engagement is now considered to be a measurement of success.

In terms of social media, engagement is how users interact with content and participate in online conversations. This study will uncover what causes people to engage on social media and identify the …

An Exploratory Analysis Of Virtual Delivery Alternatives For University-Based Animal Assisted Activities During Covid-19, Aleisha Fernandes, Yu Seon Chae, Cluny S. South

People and Animals: The International Journal of Research and Practice

Animal-assisted activities (AAAs) are being offered progressively in universities to support students’ well-being. However, with the recent health restrictions due to COVID-19, all classes and health services are being delivered remotely. Due to this, many postsecondary institutions have put a temporary pause on AAAs. Most recently, there has been a growing interest and rise in virtual AAAs being facilitated at universities in North America, which vary in duration, group size, and other organizational elements. Furthermore, prior to the pandemic there was also an interest in collaborative events that sought to combine multiple activities with AAAs. Due to the nature of …

Neurodevelopmental Processes In The Prefrontal Cortex Derailed By Chronic Hiv-1 Viral Protein Exposure, Kristen A. Mclaurin, Hailong Li, Rosemarie M. Booze, Charles F. Mactutus

Faculty Publications

Due to the widespread access to, and implementation of, combination antiretroviral therapy, individuals perinatally infected with human immunodeficiency virus type 1 (HIV-1) are living into adolescence and adulthood. Perinatally infected adolescents living with HIV-1 (pALHIV) are plagued by progressive, chronic neurocognitive impairments; the pathophysiological mechanisms underlying these deficits, however, remain understudied. A longitudinal experimental design from postnatal day (PD) 30 to PD 180 was utilized to establish the development of pyramidal neurons, and associated dendritic spines, from layers II-III of the medial prefrontal cortex (mPFC) in HIV-1 transgenic (Tg) and control animals. Three putative neuroinflammatory markers (i.e., IL-1β, IL-6, and …

Biosystems and Agricultural Engineering Faculty Publications

Food and drink is the largest manufacturing sector worldwide and has significant environmental impact in terms of resource use, emissions, and waste. However, food and drink manufacturers are restricted in addressing these issues due to the tight profit margins they operate within. The advances of two industrial digital technologies, sensors and machine learning, present manufacturers with affordable methods to collect and analyse manufacturing data and enable enhanced, evidence-based decision making. These technologies will enable manufacturers to reduce their environmental impact by making processes more flexible and efficient in terms of how they manage their resources. In this article, a methodology …

Comparative Neuropharmacology And Pharmacokinetics Of Methamphetamine And Its Thiophene Analog Methiopropamine In Rodents, Silja Skogstad Tuv, Marianne Skov-Skov Bergh, Jannike Mørch Andersen, Synne Steinsland, Vigdis Vindenes, Michael H Baumann, Marilyn A. Huestis, Inger Lise Bogen

Institute of Emerging Health Professions Faculty Papers

Methiopropamine is a novel psychoactive substance (NPS) that is associated with several cases of clinical toxicity, yet little information is available regarding its neuropharmacological prop-erties. Here, we employed in vitro and in vivo methods to compare the pharmacokinetics and neu-robiological effects of methiopropamine and its structural analog methamphetamine. Methiopro-pamine was rapidly distributed to the blood and brain after injection in C57BL/6 mice, with a phar-macokinetic profile similar to that of methamphetamine. Methiopropamine induced psychomotor activity, but higher doses were needed (Emax 12.5 mg/kg; i.p.) compared to methamphetamine (Emax 3.75 mg/kg; i.p.). A steep increase in locomotor activity was seen after …

Phytophthora root and stem rot caused by P. sojae is a destructive soybean soil-borne disease found worldwide. Discovery of genes conferring broad-spectrum resistance to the pathogen is a need to prevent the outbreak of the disease. Here, we show that soybean Rps11 is a 27.7-kb nucleotide-binding site-leucine-rich repeat (NBS-LRR or NLR) gene conferring broad-spectrum resistance to the pathogen. Rps11 is located in a genomic region harboring a cluster of large NLR genes of a single origin in soybean, and is derived from rounds of unequal recombination. Such events result in promoter fusion and LRR expansion that may contribute to the …

Passive Acoustic Monitoring And Automatic Detection Of Diel Patterns And Acoustic Structure Of Howler Monkey Roars, Leandro A. Do Nascimento, Cristian Pérez-Granados, Karen H. Beard

Wildland Resources Faculty Publications

Nighttime studies are underrepresented in ecological research. Even well-known behaviors, such as the loud call of howler monkeys, are rarely studied at night. Our goal was to help fill this knowledge gap by studying the 24 h vocal behavior of the Guianan red howler monkey (Alouatta macconnelli) and to compare the acoustic structures of howling bouts made during the day to those made at night. We used passive acoustic monitoring coupled with automatic acoustic detection to study three groups of howlers over three months in the Viruá National Park, Roraima, Brazil. The automatic classifier we built detected 171 …

Exposure Of Predatory And Scavenging Birds To Anticoagulant Rodenticides In France: Exploration Of Data From French Surveillance Programs, Meg-Anne Moriceau, Sébastien Lefebvre, Isabelle Fourel, Etienne Benoit, Florence Buronfosse-Roque, Pascal Orabi, Barnett A. Rattner, Virginie Lattard

United States Geological Survey: Staff Publications

Wild raptors are widely used to assess exposure to different environmental contaminants, including anticoagulant rodenticides (ARs). ARs are used on a global scale for rodent control, and act by disruption of the vitamin K cycle that results in haemorrhage usually accompanied by death within days. Some ARs are highly persistent and bioaccumulative, which can cause significant exposure of non-target species.We characterized AR exposure in a heterogeneous sample of dead raptors collected over 12 years (2008–2019) in south-eastern France. Residue analysis of 156 liver samples through LC-MS/MS revealed that 50% (78/156) were positive for ARs, with 13.5% (21/156) having summed second-generation …

Dna Methylation At A Nutritionally Sensitive Region Of The Pax8 Gene Is Associated With Thyroid Volume And Function In Gambian Children, Toby Candler, Noah J Kessler, Chathura J Gunasekara, Kate A Ward, Philip James, Eleonora Laritsky, Maria S Baker, Roger Dyer, Rajavel Elango, David Jeffries, Robert A Waterland, Sophie E Moore, Marian Ludgate, Andrew M Prentice, Matt J Silver

Children’s Nutrition Research Center Staff Publications

PAX8 is a key thyroid transcription factor implicated in thyroid gland differentiation and function, and PAX8 gene methylation is reported to be sensitive to the periconceptional environment. Using a novel recall-by-epigenotype study in Gambian children, we found that PAX8 hypomethylation at age 2 years is associated with a 21% increase in thyroid volume and an increase in free thyroxine (T4) at 5 to 8 years, the latter equivalent to 8.4% of the normal range. Free T4 was associated with a decrease in DXA-derived body fat and bone mineral density. Furthermore, offspring PAX8 methylation was associated with periconceptional maternal nutrition, and …

Record Of Nesting And Fledgling Depredation On Crested Caracara (Caracara Cheriway) In Its Peri-Urban Habitat In The Guadalajara Metropolitan Area, West-Central Mexico, Perla Sugey González-Ruelas, Zayra Arery Guadalupe Muñoz-González, Ana Luisa Santiago-Pérez, Luis Fernando Ramírez-López, Claudia Aurora Uribe-Mú, Verónica Carolina Rosas-Espinoza

Western North American Naturalist

Urban settings represent a challenge to most bird species, although some raptors seem to adjust to new urban environments. The Crested Caracara (Caracara cheriway) is known as an urban-tolerant species. Though caracaras are resident in west-central Mexico, there is no information about the species’ distribution, reproduction, and nesting within a metropolis such as Guadalajara. This species was using the peri-urban setting of the Guadalajara Metropolitan Area (GMA) to hunt, breed, construct its nests, and care for juveniles. To our knowledge, this is the first reported record of it breeding in a peri-urban setting in Mexico. On 15 February …

Gamifying The Crew: Effects Of Collaborative Responsive Writing Using Gamification, In Interactive Web-Based E-Books, On L2 International Students’ Motivation And Academic Vocabulary Achievement, Rabea M. Alfahad

USF Tampa Graduate Theses and Dissertations

International students usually find it challenging to adapt to English academic vocabulary (Park, 2019). The literature is interspersed with the use of a variety of technologies and technological tools to augment the knowledge of language learners regarding English academic vocabulary (Flemban, 2018). However, in this dissertation, interactive web-based e-books and two strategies to teach English academic vocabulary (gamification and collaborative responsive writing) is employed. Gamification is applying game mechanics in non-game related contexts (Groh, 2012). This study investigated the impact of these two strategies on the participants’ academic vocabulary achievement and motivation level. In so doing, interactive web-based e-books are …

Health And Wellbeing Outcomes And Social Prescribing Pathways In Community‐Based Support For Autistic Adults: A Systematic Mapping Review Of Reviews, Charlotte Featherstone, Richard A. Sharpe, Nick Axford, Sheena Asthana, Kerryn Husk

Peninsula Medical School

Adults on the autism spectrum are affected by health disparities which significantly reduce life expectancy and experience barriers to accessing healthcare. Social prescribing is a holistic approach that diverts patients from primary care to health-enhancing activities in communities. However, there has been a lack of research attention to how autistic people navigate the social prescribing pathway and the ability of these approaches to address existing disparities. This mapping review aimed to synthesise features of non-medical, community-based interventions for autistic adults to assess their suitability for a social prescribing approach. A systematic search and screening process was used to identify literature …

First Ecological Characterization Of Whip Black Coral Assemblages (Hexacorallia: Antipatharia) In The Easter Island Ecoregion, Southeastern Pacific, Jan M. Tapia-Guerra, Cynthia M. Asorey, Erin E. Easton, Daniel Wagner, Matthias Gorny, Javier Sellanes

School of Earth, Environmental, & Marine Sciences Faculty Publications

One of the main priorities of marine scientific research is to provide practical information and guidance for biodiversity conservation and management. In this context, the identification of key and fragile habitat-forming species is particularly important. Despite their ecological importance, whip corals in the order Antipatharia remain poorly studied around the world, and especially in the South Pacific. During recent expeditions to explore mesophotic and deep benthic habitats around Rapa Nui (Easter Island), dense assemblages of whip black corals were observed in situ. We here report the first detailed description of the distribution and abundance of these black coral assemblages …

IGC Proceedings (1977-2023)

In order to compare the in situ degradability of tanzania grass samples obtained as by extrusa or hand plucked, three ruminal fistulated cows were used in a completely randomized block design with split-plot scheme. Five grams of extrusa or hand harvested grasses were placed in nylon bags rumen incubated during 3, 6, 12, 24, 48, 96 and 120 hours. The degradability of DM, CP, NDF and ADF were, in this sequence, 62.59, 80.88, 50.73 and 46.65%, for hand harvested grass; and 79.53, 90.97, 71.21 and 65.68%, for extrusa. In situ degradability data of hand harvested samples were not reliable.

Herbivore Preference For Afternoon- And Morning-Cut Forages And Adoption Of Cutting Management Strategies, H. F. Mayland, J. C. Burns, D. S. Fisher, Glenn E. Shewmaker, R. Carlstrom, D. S. Cash

IGC Proceedings (1977-2023)

Photosynthesizing forage plants accumulate total nonstructural carbohydrates (TNC) during daylight, but then TNC concentrations are reduced during the night. Afternoon-cut forage (PM) has greater TNC value and thus economic value, than morning-cut (AM). Livestock prefer PM-cut hay and this can be readily demonstrated by offering animals a choice of hays cut in PM and AM. Alfalfa growers in the western United States are readily adopting PM-cutting technology to increase profits.

Near Infra-Red Measurement Of Nonstructural Carbohydrates In Alfalfa Hay, H. F. Mayland, J. C. Burns, D. S. Fisher, Glenn E. Shewmaker

IGC Proceedings (1977-2023)

Recently documented benefits from afternoon versus morning cut forage have encouraged laboratory reporting of total nonstructural carbohydrate (TNC) values as part of forage quality testing. Our objective was to determine if infra-red spectroscopy (NIRS), which is being used in many forage testing labs, could be reliably used to quantify forage sugars in hay samples. We used two alfalfa (Medicago sativa L.) sample populations that were analyzed by wet chemistry for sugars and scanned by NIRS. The first set consisted of field-dried hay samples that were oven dried at 70^oC and the second consisted of fresh, freeze-dried samples. …
