The Mental Homologies Of Mammals. Towards An Understanding Of Another Mammalsworld View, Marthe Kiley-Worthington

Theory of Mind Collection

Mammals’ mental homologies include that they look after their young, suckle and protect them; they acquire information about the world by learning. They have five types of sensory receptors and a brain to analyze the information and they feel: that is they are sentient. Mental homologies have been largely ignored by behavioural scientists since Darwin because of certain historical beliefs. This however has not been the case for people who have had to do with non-human mammals who have long recognized their mental similarities to humans. As a result, behavioural science has sponsored some inappropriate research (examples are given). The …

Transient Analysis Of Fracture Initiation In A Coupled Thermoelastic Solid, Louis Milton Brock

Mechanical Engineering Faculty Publications

An isotropic, thermoelastic solid is initially at rest at uniform (absolute) temperature, and contains a semi-infinite, plane crack. Application of in-plane and normal point forces to each face of the crack causes transient 3D growth. The related problem of discontinuities in temperature and displacement that exist on regions that exhibit dynamic similarity is first considered. Asymptotic expressions, whose inverses are valid near the crack edges for short times, are obtained in integral transform space. These lead to equations of the Wiener–Hopf type for the fracture problem. Analytical solutions are obtained and, upon inversion, subjected to a dynamic energy release rate …

Load Model Verification, Validation And Calibration Framework By Statistical Analysis On Field Data, Xiangqing Jiao, Yuan Liao, Thai Nguyen

Electrical and Computer Engineering Faculty Publications

Accurate load models are critical for power system analysis and operation. A large amount of research work has been done on load modeling. Most of the existing research focuses on developing load models, while little has been done on developing formal load model verification and validation (V&V) methodologies or procedures. Most of the existing load model validation is based on qualitative rather than quantitative analysis. In addition, not all aspects of model V&V problem have been addressed by the existing approaches. To complement the existing methods, this paper proposes a novel load model verification and validation framework that can systematically …

Student Attitudes Toward Group Discussions, Virginia Clinton, Alison E. Kelly

Educational Foundations and Research Faculty Publications

Student attitudes toward active learning techniques, such as group discussion, are often negative. The purpose of this study was to determine if an intervention informing students of the usefulness of group discussions affects their attitudes on group discussions. Students were randomly assigned to view a video and answer an essay question either on the value of group discussions (treatment) or on how group discussions were graded (control). Students in the treatment indicated group discussions as more useful as students in the control. Importantly, there were no differences in attitudes prior to the intervention. In addition, students reported their perceptions of …

Measurement Of The Multi-Tev Neutrino Interaction Cross-Section With Icecube Using Earth Absorption, Karen Andeen, The Icecube Collaboration

Physics Faculty Research and Publications

Neutrinos interact only very weakly, so they are extremely penetrating. The theoretical neutrino–nucleon interaction cross-section, however, increases with increasing neutrino energy, and neutrinos with energies above 40 teraelectronvolts (TeV) are expected to be absorbed as they pass through the Earth. Experimentally, the cross-section has been determined only at the relatively low energies (below 0.4 TeV) that are available at neutrino beams from accelerators^1,2. Here we report a measurement of neutrino absorption by the Earth using a sample of 10,784 energetic upward-going neutrino-induced muons. The flux of high-energy neutrinos transiting long paths through the Earth is attenuated compared to …

Lower–Middle Pennsylvanian Strata In The North American Midcontinent Record The Interplay Between Erosional Unroofing Of The Appalachians And Eustatic Sea-Level Rise, J.K. Kissock, E. S. Finzel, D. H. Malone, J. P. Craddock

Faculty Publications - Geography, Geology, and the Environment

Morrowan, Atokan, and Desmoinesian (Lower–Middle Pennsylvanian) clastic strata in the Forest City (Iowa, northwest Missouri, eastern Nebraska, and Kansas) and Illinois Basins on the North American midcontinent record the interaction between fluctuations in eustatic sea-level and major tectonic events. One of three major Paleozoic eustatic sea-level lows occurred near the Mississippian/Pennsylvanian boundary and was followed by a eustatic rise that continued into Late Pennsylvanian time. Alleghenian mountain building that is linked to the creation of the Pangean supercontinent also began during latest Mississippian time and continued until latest Pennsylvanian or earliest Permian time. Detrital-zircon geochronology and stratigraphic descriptions allow reconstruction …

Facilitating Student Engagement Research: A Historical Analogy For Understanding And Applying Naturalistic Inquiry, Lane G. Perry Iii, April Perry

Journal of Research Initiatives

This paper offers a historical theoretical discussion and practical perspective on the qualitative paradigm of inquiry referred to as Naturalistic Inquiry (Lincoln & Guba, 1985). Moreover, it endeavors to demonstrate the paradigm’s versatility and usefulness when attempting to illuminate phenomena that specifically occur when students experience and interact with engaging, innovative, and experientially based pedagogies (e.g., service-learning, work-integrated learning, community-based learning). This paper presents and paradigmatically supports the researchers’ worldview through a logical primacy and discussion of ontological, epistemological, axiological, and methodological perspectives (Guba & Lincoln, 2001). Following this, Naturalistic Inquiry is identified as a paradigm of inquiry that aligns …

Bioinformatic And Biophysical Analyses Of Proteins, Jonathan Catazaro

Department of Chemistry: Dissertations, Theses, and Student Research

The prevailing dogma in structural genomics is the existence of a strong correlation between protein sequence, structure, and biological function. Proteins with high sequence similarity typically have a similar, if not the same, structure and function. In many cases this logic can fail due to distantly related proteins having very low sequence similarity, a lack of a representative structure, structural novelty, or the absence of a characterized function. Further, the paradigm fails to account for dynamics, which have a significant effect on structural stability and enzymatic efficacy.

Nuclear magnetic resonance (NMR) spectroscopy is uniquely capable of solving the structure, assisting …

Characteristics Of Lithium Lanthanum Titanate Thin Films Made By Electron Beam Evaporation From Nanostructured La0.67-Xli 3xtio3 Target, Dinh Nguyen Nang, Trong Le Dinh, Long Pham Duy

ASEAN Journal on Science and Technology for Development

Bulk nanostructured perovskites of La0.67-xLi3xTiO3 (LLTO) were prepared by using thermally ball-grinding from compounds of La2O3, Li2CO3 and TiO2.

Temporo-Spectral Coherent Structure Of Turbulence And Pressure Using Fourier And Wavelet Transforms, Le Thai-Hoa, Nguyen Dong-Anh

ASEAN Journal on Science and Technology for Development

Studying the spatial distribution in coherent fields such as turbulent and turbulent-induced force ones is important to model and evaluate turbulent-induced forces and response of structures on the turbulent flows. Turbulent field-based coherent function is commonly used for the spatial distribution characteristic of induced forces in the frequency domain. This paper will focus to study spectral coherent structure of turbulence and forces in not only the frequency domain using conventional Fourier transform-based coherence, but also temporo-spectral coherent one in the time-frequency plane thanks to wavelet transform-based coherence for more understanding of the turbulence and force coherences and their spatial distributions. …

Tunable Copper Complexes For Sustainable Photocatalysis, David Kline

Posters-at-the-Capitol

Photoredox catalysis has direct applications in sustainable chemistry and thus an immense impact on our environment. With the ability to harness energy directly from the sun to catalyze useful chemical reactions, photocatalysts can help to eliminate the need for harsh reaction conditions and reduce generation of hazardous chemical waste. Photocatalysts based on Earth-abundant metals such as copper have recently emerged as sustainable alternatives to rare-earth metals including iridium and ruthenium, which are no longer required for many photocatalyzed chemical transformations.

Modular Mechanistic Networks: On Bridging Mechanistic And Phenomenological Models With Deep Neural Networks In Natural Language Processing, Simon Dobnik, John D. Kelleher

Books/Book chapters

Natural language processing (NLP) can be done using either top-down (theory driven) and bottom-up (data driven) approaches, which we call mechanistic and phenomenological respectively. The approaches are frequently considered to stand in opposition to each other. Examining some recent approaches in deep learning we argue that deep neural networks incorporate both perspectives and, furthermore, that leveraging this aspect of deep learning may help in solving complex problems within language technology, such as modelling language and perception in the domain of spatial cognition.

Tracking You Through Dns Traffic: Linking User Sessions By Clustering With Dirichlet Mixture Model, Mingxuan Sun, Junjie Zhang, Guangyue Xu, Dae Wook Kim

Computer Science and Engineering Faculty Publications

The Domain Name System (DNS), which does not encrypt domain names such as "bank.us" and "dentalcare.com", commonly accurately reflects the specific network services. Therefore, DNS-based behavioral analysis is extremely attractive for many applications such as forensics investigation and online advertisement. Traditionally, a user can be trivially and uniquely identified by the device’s IP address if it is static (i.e., a desktop or a laptop). As more and more wireless and mobile devices are deeply ingrained in our lives and the dynamic IP address such as DHCP has been widely applied, it becomes almost impossible to use one IP address to …
