Gesture As A Window To Justification And Proof, Caro C. Williams-Pierce

Mathematics and Statistics Faculty Scholarship

The role of the body, particularly gesture, in supporting mathematical reasoning is an emerging area of research in mathematics education. In the present study, we examine undergraduate students providing a justification for a task about a system of alternating gears, which involves concepts of number relating to even/odd patterns. Some participants were directed to perform gestures relevant to alternation and parity before attempting their justification, while others were not. Although these directed actions did not seem to influence the gestures participants used to solve the problem, we found an important relationship between gesture and mathematical reasoning. In particular, certain types …

Wallace And Incipient Structures: A World Of "More Recondite" Influences, Charles H. Smith

DLPS Faculty Publications

Alfred Russel Wallace is well-known for his co-discovery of the principle of natural selection. Natural selection is usually considered a process, but it is not clear that Wallace regarded it in exactly these terms. In fact he more likely thought of the relationships involved as representing what we would now term a “state space,” a negative feedback loop wherein populations are maintained at healthy levels through elimination of the unfit. Both before and after the advent of natural selection Wallace clung to the idea that “more recondite forces” were shaping the nature and direction of evolution; this is especially evident …

Nfib V. Sebelius And The Transformation Of The Taxing Power, Barry Cushman

Notre Dame Law Review

In National Federation of Independent Business v. Sebelius, Chief Justice Roberts wrote for a majority of five Justices in holding that the “shared responsibility payment” required by the Patient Protection and Affordable Care Act (“ACA”) constituted an imposition of a “tax” rather than a “penalty.” Thus, even though the Chief Justice and four other Justices had concluded that the provision was not a legitimate exercise of the commerce power, the Court held that it was a valid exercise of the taxing power.

The origin of the distinction between taxes and penalties in taxing power jurisprudence is found in the 1922 …

Legal Diversification, Kelli A. Alces

Scholarly Publications

The greatest protection investors have from the risks associated with capital investment is diversification. This Essay introduces a new dimension of diversification for investors: legal diversification. Legal diversification of investment means building a portfolio of securities that are governed by a variety of legal rules. Legal diversification protects investors from the risk that a particular method of minimizing agency costs will prove ineffective and allows investors to own securities in a variety of firms, with each security governed by the most efficient set of legal rules given the circumstances of the investment. Diversification of investment by legal rules is possible …

Finding Specifications Of While Statements Using Patterns, Aditi Barua, Yoonsik Cheon

Departmental Technical Reports (CS)

A formal correctness proof of code containing loops such as while statements typically uses the technique of proof-by-induction, and often the most difficult part of carrying out an inductive proof is formulating a correct induction hypothesis, a specification for a loop statement. An incorrect induction hypothesis will surely lead to a proof failure. In this paper we propose a systematic way for identifying specifications of while statements. The key idea of our approach is to categorize and document common patterns of while statements along with their specifications. This is based on our observation that similarly-structured while statements frequently have similarly-structured …

Sotomayor's Empathy Moves The Court A Step Closer To Equitable Adjudication, Veronica Couzo

Notre Dame Law Review

On August 6, 2009, then-Judge, now-Justice, Sonia Sotomayor was confirmed as the nation’s first Latina Supreme Court Justice. While many Latinos embraced the idea of having “Sonia from the Bronx” on the bench, others were fearful that her jurisprudence, combined with her background, would result in “reverse racism.” These fears, while arguably unfounded at the time, have been completely dispelled. Just as Justice Thurgood Marshall transformed the adjudications of the Supreme Court through experiential discourse, so too, to a lesser extent, has Justice Sotomayor. In both oral arguments and written opinions, Justice Sonia Sotomayor has demonstrated educative leadership—enlightening her colleagues …

The Evolutionary History Of Cetacean Brain And Body Size, Stephen H. Montgomery, Jonathan H. Geisler, Michael R. Mcgowen, Charlotte Fox, Lori Marino, John Gatesy

Veterinary Science and Medicine Collection

Cetaceans rival primates in brain size relative to body size and include species with the largest brains and biggest bodies to have ever evolved. Cetaceans are remarkably diverse, varying in both phenotypes by several orders of magnitude, with notable differences between the two extant suborders, Mysticeti and Odontoceti.We analyzed the evolutionary history of brain and body mass, and relative brain size measured by the encephalization quotient (EQ), using a data set of extinct and extant taxa to capture temporal variation in the mode and direction of evolution. Our results suggest that cetacean brain and body mass evolved under strong directional …

An Analysis Of The Use Of Dogs In Predicting Human Toxicology And Drug Safety, Jarrod Bailey, Michelle Thew, Michael Balls

Laboratory Experiments Collection

Dogs remain the main non-rodent species in preclinical drug development. Despite the current dearth of new drug approvals and meagre pipelines, this continues, with little supportive evidence of its value or necessity. To estimate the evidential weight provided by canine data to the probability that a new drug may be toxic to humans, we have calculated Likelihood Ratios (LRs) for an extensive dataset of 2,366 drugs with both animal and human data, including tissue-level effects and Medical Dictionary for Regulatory Activities (MedDRA) Level 1–4 biomedical observations. The resulting LRs show that the absence of toxicity in dogs provides virtually no …

Discrimination Of Familiar Human Faces In Dogs (Canis Familiaris), Ludwig Huber, Anaïs Racca, Billy Scaf, Zsófia Virányi, Friederike Range

Recognition Collection

Faces are an important visual category for many taxa, and the human face is no exception to this. Because faces differ in subtle ways and possess many idiosyncratic features, they provide a rich source of perceptual cues. A fair amount of those cues are learned through social interactions and are used for future identification of individual humans. These effects of individual experience can be studied particularly well in hetero-specific face perception. Domestic dogs represent a perfect model in this respect, due to their proved ability to extract important information from the human face in socio-communicative interactions. There is also …

The Impact Of Reducing Nitrogen Fertilizer In Iceberg Head Lettuce, Jason Acquistapace

Agricultural Education and Communication

The impact of Nitrogen use in Iceberg lettuce was studied by measuring the weight and size of lettuce heads. A standard nitrogen application based on traditional commercial production was determined and portions of commercial fields (401 and 406) were designated for testing. Based on the standard, three fertilizer treatments (40%, 60%, and 80% of the control) were tested against the control in fields 401 and 406. The results indicated there was no difference in the weight of lettuce heads when treated with the relative fertilizer percentages. However, the size of lettuce heads decreased as the relative fertilizer percentages decreased. This …

This research were conducted at California Polytechnic State University San Luis Obispo throughout the Winter, Spring, and Fall quarters of 2013. The data presented in this paper was taken on the night of October 20, 2013 at the Cal Poly San Luis Obispo Astronomical Observatory and was reduced using IRAF software available on campus. This report describes the results of an observation of two bright XM geostationary satellites and the steps taken to get to those results. The average magnitude values of the XM-1 and XM-2 satellites were 13.753±0.007 and 14.015±0.007 respectively. The magnitude varied an average of 0.1 magnitudes …

Phylogeography Of The California Sheephead, Semicossyphus Pulcher: The Role Of Deep Reefs As Stepping Stones And Pathways To Antitropicality, Marloes Poortvliet, Gary C. Longo, Kimberly Selkoe, Paul H. Berber, Crow White, Jennifer E. Caselle, Alejandro Perez-Matus, Steven D. Gaines, Giacomo Bernardi

Biological Sciences

In the past decade, the study of dispersal of marine organisms has shifted from focusing predominantly on the larval stage to a recent interest in adult movement. Antitropical distributions provide a unique system to assess vagility and dispersal. In this study, we have focused on an antitropical wrasse genus, Semicossyphus, which includes the California sheephead, S. pulcher, and Darwin's sheephead, S. darwini. Using a phylogenetic approach based on mitochondrial and nuclear markers, and a population genetic approach based on mitochondrial control region sequences and 10 microsatellite loci, we compared the phylogenetic relationships of these two species, as well …

Student Success And Perceptions Of Course Satisfaction In Face-To-Face, Hybrid, And Online Sections Of Introductory Biology Classes At Three, Open Enrollment, Two-Year Colleges In Southern Missouri, Joyce Diane Hill

Dissertations

Introductory biology courses at two-year, open enrollment colleges in America are presented in a variety of different course delivery formats. Traditionally, most students have enrolled in seated or face-to-face (F2F) lectures and laboratories. There is increased demand for courses presented online or in a hybrid format, although some studies report higher attrition rates, and lower grades for these course delivery formats. The purpose of this study was to examine if there were academic differences among F2F, hybrid, or online introductory biology courses by analyzing pre-course and post-course assessment scores, final grades, attrition rates, and students’ perceptions of course satisfaction. This …

Teachers' Perception Of The English Language Curriculum In Libyan Public Schools: An Investigation And Assessment Of Implementation Process Of English Curriculum In Libyan Public High Schools, Salem Altaieb

Electronic Theses and Dissertations

With the advent of globalization and technological development, English has become a necessary tool of international communication in many areas such as education, business, politics, commerce, science, and technology throughout the world. Also, English has become the most widely taught foreign language in the world (Kachru &Nelson, 1996). Moreover, the issue of successful implementation of the English language curriculum has been the focus of a number of studies. In the case of Libya, however, little research has been conducted on teachers' perceptions of the new English language curriculum in Libyan high schools. Thus, teachers' voices have not been examined or …

Defects And Dark Current In Organic Photovoltaics And Impacts On Device Physics, Xin Jiang

Electronic Theses and Dissertations

In this dissertation, we discussed the shape, energy level and density of defects in Organic Photovoltaic (OPV) devices by both theoretical and experimental methods. The energy band structure and intrinsic junctions of general standard and inverted OPV devices are investigated in detail. Transportation of separated holes and electrons in both structures are well analyzed. In chapter II, we developed a Monte-Carlo model to simulate charge transport process in organic materials. Marcus theory is applied to calculate the carrier transfer rate to build up hopping process in ideal lattices. Results of this model showed several properties of carriers regarding mobility, reorganization …

Formative Assessment In Law Doctrinal Classes: Rethinking Grade Appeals, Roberto L. Corrada

Sturm College of Law: Faculty Scholarship

This article describes a practice I began several years ago to encourage students to review their midterm exams and to learn formatively from their exam and their review of it. The practice involves encouraging midterm grade appeals coupled with a high success rate (what I term, "robust" grade appeals). The practice has a number of ancillary benefits, I believe, in addition to the central benefits—getting students to learn more about law, learn from their mistakes and write better exams by meaningfully engaging and critiquing their own work on exams. This article describes and discusses the advantages and disadvantages of such …

Semantics-Empowered Big Data Processing With Applications, Krishnaprasad Thirunarayan, Amit P. Sheth

Kno.e.sis Publications

We discuss the nature of Big Data and address the role of semantics in analyzing and processing Big Data that arises in the context of Physical-Cyber-Social Systems. We organize our research around the Five Vs of Big Data, where four of the Vs are harnessed to produce the fifth V - value. To handle the challenge of Volume, we advocate semantic perception that can convert low-level observational data to higher-level abstractions more suitable for decision-making. To handle the challenge of Variety, we resort to the use of semantic models and annotations of data so that much of the intelligent processing …

Molecular Detection Of Culture-Confirmed Bacterial Bloodstream Infections With Limited Enrichment Time, Miranda S. Moore, Chase D. Mccann, Jeanne Jordan

Epidemiology Faculty Publications

Conventional blood culturing using automated instrumentation with phenotypic identification requires a significant amount of time to generate results. This study investigated the speed and accuracy of results generated using PCR and pyrosequencing compared to the time required to obtain Gram stain results and final culture identification for cases of culture-confirmed bloodstream infections. Research and physician-ordered blood cultures were drawn concurrently. Aliquots of the incubating research blood culture fluid were removed hourly between 5 and 8 h, at 24 h, and again at 5 days. DNA was extracted from these 6 time point aliquots and analyzed by PCR and pyrosequencing for …

Filtering Of Ms/Ms Data For Peptide Identification, Jason Gallia, Katelyn Lavrich, Anna Tan-Wilson, Patrick H. Madden

Biological Sciences Faculty Scholarship

Background: The identification of proteins based on analysis of tandem mass spectrometry (MS/MS) data is a valuable tool that is not fully realized because of the difficulty in carrying out automated analysis of large numbers of spectra. MS/MS spectra consist of peaks that represent each peptide fragment, usually b and y ions, with experimentally determined mass to charge ratios. Whether the strategy employed is database matching or De Novo sequencing, a major obstacle is distinguishing signal from noise. Improved ability to distinguish signal peaks of low intensity from background noise increases the likelihood of correctly identifying the peptide, as valuable …

The Impact Of Research And Development On Economic Growth And Productivity In The Us States, Luisa Blanco, James Prieger, Ji Gu

School of Public Policy Working Papers

We estimate the impact of R&D on TFP and output in the private sector at the state level in the US from 1963 to 2007. R&D has a large effect on both output and TFP at the state level in the long run. The R&D elasticity in a state averages 0.056 to 0.143, implying returns to state GDP from R&D spending of 83% to 213%. There are also positive R&D spillovers, with 77% of the total returns accruing to other states. The R&D elasticities are either stable or increase slightly after 1993. The effects of R&D are dependent on the …
