The Lesson Of Confucius For Today’S America: Education In Ethics Is The Road To Building A Just And Peaceful Society, Yeomin Yoon Jun 2025

The Lesson Of Confucius For Today’S America: Education In Ethics Is The Road To Building A Just And Peaceful Society, Yeomin Yoon

KAUPA Letters

According to Confucius, what confers humans their special status and dignity among beings in nature is the moral virtues they can achieve. Humans should build good character, for which they need education to acquire values. He found no correlation between the ability to learn and the socio-economic status. He believed that people with the ability to learn deserved an opportunity to learn. Confucius would not approve of the prevalent American conception of education as transmitting technical knowledge and skills to students without an education in the values to promote by their use. Purely technical education would be an oxymoron for …

Effect Of Response Bias On Threshold Estimates In Confounded N-Alternative Optional Choice Experiments, James J. Blaha, Benjamin T. Backus, Thaddeus B. Czuba

MODVIS Workshop

Three modifications of the familiar 2-AFC task can be useful when collecting data to estimate sensory thresholds from unpracticed participants: (1) Make responding optional, which relieves the participant from having to guess when they are uncertain; (2) Provide N>2 alternatives, which reduces the number of trials to estimate threshold; and (3) Confound the alternatives with an independent variable, for example by having participants choose visual field locations as alternatives when measuring threshold separately at each visual field location, which reduces the number of trials through multiplexing. The N-alternative optional-choice experiment (N-AOC) and its confounded variant have not been studied …


Bell Telephone System’S Preeminent Role In The Growth Of Industrial Design, Ralph O. Meyer, Russell A. Flinchum May 2025

Bell Telephone System’S Preeminent Role In The Growth Of Industrial Design, Ralph O. Meyer, Russell A. Flinchum

Purdue University Press Books

Histories of design pay scant attention to the corded telephone, which played an immeasurable role in early communication. Although the Bell System, with many Nobel Prizes, is justly acknowledged for its technical prowess, it should also be recognized for its early and considerable impact on the developing discipline of industrial design. In 1930, young Henry Dreyfuss, who would later become known as a pioneer of industrial design, was retained by the Bell System as a design consultant and matured in that environment. With substantial input from Bell System engineers, Dreyfuss and his staff produced attractive telephone designs that were manufactured …

Using Neural Networks To Better Understand Static And Dynamic Components Of Facial Expression Recognition, Yi-Fan Li, Anne Bibiana Sereno May 2025

Using Neural Networks To Better Understand Static And Dynamic Components Of Facial Expression Recognition, Yi-Fan Li, Anne Bibiana Sereno

MODVIS Workshop

Facial expressions are crucial social information for human communication. In the real world, facial expressions are dynamic; however, much of existing research in facial expressions relies on static stimuli. This static approach may limit the ecological validity of our understanding of the emotional information on faces. Our study aims to investigate the dynamic and static information contained in different emotional categories of facial expressions (e.g., happy, sad). Four convolutional neural networks are introduced as models to be trained with a large-scale dynamic facial expression dataset (short videoclips of 16 frames of 7 different emotional categories) in four different ways: ordered …

Somewhere In The Middle: Assistant Directors’ Leadership, Labor, And Power In Writing Centers, Keri L. Carter, John L. Carter Apr 2025

Somewhere In The Middle: Assistant Directors’ Leadership, Labor, And Power In Writing Centers, Keri L. Carter, John L. Carter

The Writing Center Journal

The position of writing center assistant director resides in the middle of the often blurry lines of hierarchy. While many writing centers advocate for team leadership, the fact remains that universities are steeped in bureaucratic tradition familiar to university leaders, students, and tutors. Assistant directors accomplish tasks that keep the day-to- day center functioning, yet these tasks equate to sometimes invisible work in the center and often invisible work in the university as a whole. Furthermore, research on assistant directors’ roles, labor, and identities is exceedingly limited. Thus, the purpose of this qualitative, phenomenological study is to understand how hierarchies …

Ultrasonic vocalizations (USVs) were recorded every day for 5 days (baseline), in male and female Long-Evans rats (N = 36, ages: 3–4 months) using an anticipatory reward paradigm. Next, rats were dehydrated (N = 18) using a published …


Morphological Awareness: An Avenue For Improving Vocabulary, Word Recognition, Spelling And Reading Comprehension, Chenell Loudermill Apr 2025

Morphological Awareness: An Avenue For Improving Vocabulary, Word Recognition, Spelling And Reading Comprehension, Chenell Loudermill

Science of Reading

Learning requires the integration of many skills, with language development being a crucial foundational aspect. Language development across five domains-phonology (the sounds within a language), morphology (word structure/formation), semantics (word meaning), syntax (sentence structure/grammar), and pragmatics (use in varying contexts)-unequivocally supports the acquisition of reading and writing skills. Specifically, morphological knowledge is vital for improving vocabulary, word recognition, spelling and reading comprehension. This practice brief provides an overview of morphological awareness and derived words, provides a rationale for teaching morphological awareness, and instructional strategies supported by science.
