Into Me See: Visibility, Recognition, And The Need To Be Seen In Kazuo Ishiguro’S Never Let Me Go, Vicki L. Wine Carney

Anthós

While critical scholarship on Kazuo Ishiguro’s Never Let Me Go often emphasizes bioethics, transhumanism, and the commodification of life, this lens overlooks the novel’s profound engagement with the psychological necessity of visibility. This paper argues that the tragedy of the clones is fundamentally a crisis of recognition, where invisibility is not incidental but structurally produced to facilitate exploitation. Drawing on Caroline Levine’s concept of the "Form of Utility" and Axel Honneth’s Theory of Recognition, this study examines how systemic indoctrination and objectification deny the clones their innate humanity to soothe the conscience of the "normals." Furthermore, it analyzes the characters’ …

Our exploratory tests involved 117 scans to evaluate scanning parameters, scanning board types, bone stabilization, scan mode and size, and region of interest placement. Results indicated that mean BMC or aBMD were each significantly different when scanned on a forearm positioner board …

Case-Based Learning In Biology Education: A Systematic Literature Review, Elsje Theodora Maasawet, Jullya Christin Kolow

Journal of Educational Technology Development and Exchange (JETDE)

Biology education often relies on content-intensive instructional materials that may encourage rote memorisation rather than conceptual understanding, potentially contributing to misconceptions. Case-Based Learning (CBL) offers an alternative by engaging students in applying biological concepts to authentic, real-life cases and promoting meaningful learning. Despite growing empirical interest in CBL, no systematic literature review has specifically synthesised its application in biology education. This study therefore examined publication trends, learning skills addressed, and conceptualisations of CBL in biology education. Relevant literature was retrieved from Scopus and Web of Science using “Case-Based Learning” as the search term. Following PRISMA-guided screening, 42 articles were included …

Engineering A Bioactive Pmma−Silica Hybrid Scaffold For Enhanced Bone Regeneration, Wai Ching Liu

Department of Food and Health Sciences

Bone health is crucial for maintaining mobility, structural integrity, and overall well-being. However, bone-related surgeries are the second most common type of tissue transplant worldwide. A reliable and bioactive material is needed to address these issues. This has led to growing interest in bone tissue engineering (BTE) as a viable substitute strategy. Poly(methyl methacrylate) (PMMA) is a commonly utilized material in implant fixation and bone tissue applications due to its mechanical and chemical stability and ease of processing. However, its low bioactivity and poor osseointegration limit its effectiveness in bone repair, posing a significant technical challenge. In this study, we …

Department of Food and Health Sciences

In this work, iron−tantalum oxide nanoparticles (FeTaOx NPs) with a gold coating modified by Angiopep-2 (FeTaOx@Au-ANG) were developed to achieve dual-modality imaging and magnetically induced hyperthermia therapy for glioma. The 13.5 nm sized FeTaOx@Au-ANG NPs’ exhibited superparamagnetic behavior with excellent dual T1/T2-weighted MRI contrast of Fe existence and enhanced X-ray attenuation for computed tomography (CT) imaging, enabling accurate tumor localization through complementary imaging modalities. The incorporation of Ta and Au not only improved biocompatibility but also provided a high CT contrast effect. Upon magnetic stimulation, the NPs efficiently elevated the intratumoral temperature, leading to a significant (∼90%) reduction in glioma …

Elephant Economics And Agrarian Transitions: Conditions For Benefiting From Elephant Tourism Market In An Upland Karen (Paganyaw) Village, Xiaoyun Neo, Aswin Baharuddin, Nur Fadilah Sunardi

Forest and Society

In rural, upland northern Thailand, Indigenous Karen (Paganyaw) communities have long practiced diversified subsistence cultivation and forest-based livelihoods. Yet state conservation policies and tourism-led development are reshaping these agrarian systems and livelihoods. This paper explores how one Karen (Paganyaw) community in Chiang Mai province reconfigures its livelihood strategies amid the decline of swidden cultivation and the rise of elephant tourism as a new rural economy. Beyond subsistence cultivation, villagers are seeking to diversify their households and personal income by participating in this new economic sector. We argue that the transition out of small-scale agriculture into tourism is not a neutral …

Nebraska Beef Cattle Reports

Summary with Implications

A receiving study was conducted to evaluate the HerdDogg remote sensing tag for the detection of morbidity in newly received steers. Treatments were assigned to cattle in the order they came through the chute, and those included a treatment whereby pen-riders evaluated the cattle and made the decision on when to treat (Pen-Rider), compared to the HerdDogg remote sensing ear tag that solely identified and flagged cattle in need of treatment (TAG). Cattle were fed for 41 days before being weighed off the receiving trial. While no differences in performance were observed, the TAG treatment had a …

Use Of Virtual Fences To Co-Fence Two Groups Of Cattle With Adjacent Virtual Boundaries, Thomas E. Aquino, Mary E. Drewnoski, Biquan Zhao, Pedro Henrique Jota Fernandes, Isaque F. Vicci, Mitchell B. Stephenson, Yijie Xiong

Nebraska Beef Cattle Reports

Summary with Implications

While virtual fencing (VF) has proven effective in managing cattle, limited data exist on using it to manage two separate groups of cattle within the same area. If successful, this approach could reduce infrastructure costs and increase management flexibility. In this trial, VF-trained steers (n = 39) were placed in pastures with either no neighboring cattle (isolated) or next to a separate group with only a VF boundary between them (co-fenced). Containment exceeded 99% across all cattle, demonstrating that VF creates effective boundaries regardless of fence treatment. There was no statistical difference in the number of audio …

Nebraska Beef Cattle Reports

Summary with Implications

This study evaluated the impact of high-pressure processing (HPP) on color, oxidative stability, and tenderness of tenderloins (psoas major) from cull cows to determine if HPP could enhance their marketability. Forty cull cow tenderloins were treated at two different HPP pressures and two different holding times, then assessed for instrumental and visual color, lipid oxidation, and Warner-Bratzler shear force during a 7-day stimulated shelf period. HPP increased initial lightness, especially at the highest pressure and longest holding time and improved redness initially. However, redness declined, and discoloration increased over the 7-day period, particularly after processing at higher …

Using High-Pressure Processing To Improve Dark-Cutting Beef Color In Tenderloins, Ashley A. Hahn, Leila G. Venzor, Shelley A. Curry, Grace C. Johnson, Mary-Grace C. Danao, Ranjith Ramanathan, Gary A. Sullivan, Jordan C. Wicks

Nebraska Beef Cattle Reports

Summary with Implications

Dark-cutting beef is a quality defect that negatively impacts consumer appeal and affects the carcass value for both producers and meat processors. These economic losses stem from poor visual appearance and reduced consumer appeal in the retail setting. Notably, different muscles within a carcass exhibit varying degrees of color stability which can influence how dark-cutting manifests across cuts. Therefore, this study aimed to examine the effect of high-pressure processing (HPP) on dark-cutting color-labile muscle. Dark-cutting and normal tenderloins were collected and portioned into two equal sections. Dark-cutting tenderloins were assigned one of 3 treatments: No HPP, 300 …

Defining The Parameters Of High-Pressure Processing To Improve The Quality Of Dark-Cutting Beef, Ashley A. Hahn, Leila G. Venzor, Shelley A. Curry, Grace C. Johnson, Mary-Grace C. Danao, Ranjith Ramanathan, Jordan C. Wicks, Gary A. Sullivan

Nebraska Beef Cattle Reports

Summary with Implications

Dark-cutting beef is a result of preharvest stress and devalues the resulting carcass. High-pressure processing (HPP) has been recently identified as a potential strategy to improve the undesirable appearance of dark-cutting beef. Dark-cutting beef strip loins were collected from a local processing facility, sectioned, and assigned an HPP pressure (300 or 450 MPa) and holding time (0, 1, 30, 60, or 90 s). Overall, HPP increased the lightness and redness of dark-cutting beef, particularly the longer the pressure was held at both pressure levels. Additionally, negative effects such as increased meat discoloration, decreased tenderness, and increased rancidity …

Evaluating Sorghum X Sudangrass Seed Digestibility, Evan Blank, Thomas E. Aquino, Mary E. Drewnoski

Nebraska Beef Cattle Reports

Summary with Implications

A sorghum-sudangrass hybrid was swathed in the hard dough stage and grazed by growing steers from November 2023 to January 2024. Steers appeared to select the seedheads when grazing. The seed made up approximately 12.6% of swathed forage mass, but its energy contribution appears limited due to poor digestibility. When incubated whole, only 23% of dry matter and 13% of starch was digestible. Grinding improved digestibility but still left 40% of the dry matter and over 85% of starch unavailable. Weathering over two months did not improve digestibility, indicating the seed coat remains intact through winter. Compared …

Comparison Of Spayed Heifer Performance To Intact Heifers Fed Melengestrol Acetate On Feedlot Performance And Carcass Characteristics, Tate S. Johnson, Rebecca L. Mcdermott, Halden J. Clark, Jim C. Macdonald, Jessica L. Sperber

Nebraska Beef Cattle Reports

Summary with Implications

Pregnancy and estrous cycle management are critical considerations when feeding intact heifers in the feedyard. Alternatively, producers can opt to spay heifers, which eliminates hormonal fluctuations associated with the estrous cycle. A proportion of U.S. feedlots have spayed heifers on feed, although there is limited data comparing the performance of spayed heifers to intact heifers. A commercial feedlot experiment was conducted to compare performance between spayed and intact heifers fed melengestrol acetate. Intact heifers had greater ADG and tended to have greater DMI compared to spayed heifers, although no difference in feed conversion was observed. Carcass weight …

Markov Chain Wave Generative Adversarial Network For Bee Bioacoustic Signal Synthesis, Kumudu Samarappuli, Iman Ardekani, Mahsa Mohaghegh, Abdolhossein Sarrafzadeh

Electrical & Computer Engineering Faculty Publications

This paper presents a framework for synthesizing bee bioacoustic signals associated with hive events. While existing approaches like WaveGAN have shown promise in audio generation, they often fail to preserve the subtle temporal and spectral features of bioacoustic signals critical for event-specific classification. The proposed method, MCWaveGAN, extends WaveGAN with a Markov Chain refinement stage, producing synthetic signals that more closely match the distribution of real bioacoustic data. Experimental results show that this method captures signal characteristics more effectively than WaveGAN alone. Furthermore, when integrated into a classifier, synthesized signals improved hive status prediction accuracy. These results highlight the potential …
