Distaste: Joyce Carol Oates And Food, David Rutledge

Bearing Witness: Joyce Carol Oates Studies

Distaste: Joyce Carol Oates and Food

Abstract

In many of her short stories and novels, Joyce Carol Oates depicts an unhealthy relationship with food. The range of these unhealthy relationships is wide, from overeating to the point of suicide, in Expensive People, to starving oneself in an attempt to deny one’s physical nature, in “Orange” and them. Overindulgence is a means for attempting to fill that space where the soul should be; undereating is often an attempt to deny one’s place in the social world. The eating disorders she portrays are rooted in both personal and social causes. …

Directional Secretory Response Of Double Stranded Rna-Induced Thymic Stromal Lymphopoetin (Tslp) And Ccl11/Eotaxin-1 In Human Asthmatic Airways, Gustavo Nino, Shehlanoor Huseni, Geovanny F. Perez, Krishna Pancham, Humaira Mubeen, Aleeza Abeesi, Justin Wang, Stephen Eng, Anamaris M. Colberg-Poley, Mary C. Rose

Pediatrics Faculty Publications

Background

Thymic stromal lymphoproetin (TSLP) is a cytokine secreted by the airway epithelium in response to respiratory viruses and it is known to promote allergic Th2 responses in asthma. This study investigated whether virally-induced secretion of TSLP is directional in nature (apical vs. basolateral) and/or if there are TSLP-mediated effects occurring at both sides of the bronchial epithelial barrier in the asthmatic state.

Methods

Primary human bronchial epithelial cells (HBEC) from control (n = 3) and asthmatic (n = 3) donors were differentiated into polarized respiratory tract epithelium under air-liquid interface (ALI) conditions and treated apically with dsRNA (viral surrogate) …

Authenticity In Constructivist Inquiry: Assessing An Elusive Construct, Patrick Shannon, Elyse Hambacher

Education

Methodological rigor in constructivist inquiry is established through an assessment of trustworthiness and authenticity. Trustworthiness parallels the positivistic concepts of internal and external validity, focusing on an assessment of the inquiry process. Authenticity, however, is unique to constructivist inquiry and has no parallel in the positivistic paradigm. Authenticity involves an assessment of the meaningfulness and usefulness of interactive inquiry processes and social change that results from these processes. However, the techniques for ascertaining authenticity are in the early stages of development. Therefore, the purpose of this article is to describe a process for assessing authenticity in a constructivist inquiry. A …

In Search Of The X2Bo And X2Bs (X = H, F) Free Radicals: Ab Initio Studies Of Their Spectroscopic Signatures, Dennis J. Clouthier

Chemistry Faculty Publications

The F₂BO free radical is a known, although little studied, species but similar X₂BY (X = H, D, F; Y = O, S) molecules are largely unknown. High level ab initio methods have been used to predict the molecular structures, vibrational frequencies (in cm^-1), and relative energies of the ground and first two excited electronic states of these free radicals, as an aid to their eventual spectroscopic identification. The chosen theoretical methods and basis sets were tested on F₂BO and found to give good agreement with the known experimental quantities. In particular, …

Sulfur Vacancies In Photorefractive Sn2P2S6 Crystals, Eric M. Golden, Sergey A. Basun, A. A. Grabar, I. M. Stoika, Nancy C. Giles, D. R. Evans, Larry E. Halliburton

Faculty Publications

A photoinduced electron paramagnetic resonance (EPR) spectrum in single crystals of Sn2P2S6 (SPS) is assigned to an electron trapped at a sulfur vacancy. These vacancies are unintentionally present in undoped SPS crystals and are expected to play an important role in the photorefractive behavior of the material. Nonparamagnetic sulfur vacancies are formed during the initial growth of the crystal. Subsequent illumination below 100 K with 442 nm laser light easily converts these vacancies to EPR-active defects. The resulting S = 1/2 spectrum shows well-resolved and nearly isotropic hyperfine interactions with two P ions and two Sn ions. Partially resolved interactions …

Pedagogies Of Possibility Within The Disciplines: Critical Information Literacy And Literatures In English, Heidi L. M. Jacobs

Communications in Information Literacy

While most disciplines have responded to the generic openness of the ACRL Standards by creating discipline-specific guidelines and competencies, there is a need for us to consider other ways to approach information literacy in the disciplines. Critical information literacy reminds us to engage ourselves and our students with what Freire described as "problem-posing education," which "bases itself on creativity and stimulates true reflection and action upon reality" (84). This article discusses how information literacy work in literatures in English could engage students and librarians in the act of collective problem-posing about the discipline. Drawing upon critical information literacy's emphasis on …

How We Got Here: A Historical Look At The Academic Teaching Library And The Role Of The Teaching Librarian, Susan Andriette Ariew

Communications in Information Literacy

This paper outlines a brief history of the academic teaching library and, in consequence, it examines the changing role of librarians. As part of that history, the paper also discusses distinctions among various terms used to describe instructional activities in teaching libraries, such as "bibliographic instruction" and "information literacy." Finally, amidst the renewed debates about the definition of information literacy and the Information Literacy Competency Standards, it attempts to answer the question, "What is a teaching Library?"

Center Pivot Sprinkler Distribution Uniformity Impacts On The Spatial Variability Of Evapotranspiration, Daniel Howes, Sean Ellenson, Lucas Hoffmann, Franklin Gaudi

BioResource and Agricultural Engineering

Understanding variable evapotranspiration (ET) throughout a field can help maximize yield on a per-acre basis, as well as assist with proper irrigation scheduling. The results from this study indicate that irrigation system distribution uniformity (DU) has a significant effect on the uniformity of ET during water-stressed periods. The study site involved intensely managed forage (alfalfa and winter grain hay) irrigated by center pivots being supplied with reclaimed water near Palmdale, California. During spring and early summer 2007 the center pivots were operating under deficit irrigation. In 2010, after the installation of reservoirs, water was applied to meet full evapotranspiration (ETc) …

New Measures Of Economic Security And Development: Savings Goals For Short-Term And Long-Term Economic Needs, Yunju Nam, Yungsoo Lee, Shawn Mcmahon, Michael Sherraden

Center for Social Development Research

The long-term economic security and development of a family depend largely upon saving and asset-accumulation, yet most measures of economic well-being focus on short-term consumption needs. This study takes a broader view, developing precautionary, retirement, homeownership and education savings goals. Together these savings goals constitute a new set of asset-based measures of family financial well-being. Estimated savings needs depend upon family type and other assumptions, and we consider investment gains and differences in dollar values over time in our calculations. This study shows that families should save $155 to $572 every month to address all four savings needs. The number …

Peer Review Of Teaching: Best Practices For A Non-Programmatic Approach, Jaena Alabi, William H. Weare, Jr.

Communications in Information Literacy

Many academic librarians who provide library instruction have never received formal training in educational theory and methods. In an effort to bridge this gap and improve the teaching skills of instruction librarians, some academic libraries have established peer review of teaching programs. Despite the recognized benefits of peer review, it may not be feasible for every library to establish such a program. In an effort to aid those who are interested in peer review, but who may not be able to participate in a formal program, the authors identify the principles of peer review that can be applied on a …

Chalcogen Bonds In Complexes Of Soxy (X, Y = F, Cl) With Nitrogen Bases, Luis Miguel Azofra, Ibon Alkorta, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

SOF2, SOFCl, and SOCl2 were each paired with a series of N bases. The potential energy surface of the binary complexes were characterized by MP2 calculations with double and triple-ξ basis sets, extrapolated to complete sets. The most stable configurations contained a S···N chalcogen bond with interaction energies as high as 6.8 kcal/mol. These structures are stabilized by a Nlp→σ*(S−Z) electron transfer (Z = O, F, Cl), complemented by Coulombicattraction of N to theσ-hole opposite the Z atom. N···S−F and N···S−Cl chalcogen bonds are stronger than N···S = O interactions.Formation of each chalcogen bond elongates all of the internalcovalent bonds …

Tensile Testing To Quantitate The Anisotropy And Strain Hardening Of Mozzarella Cheese, Ramona Bast, Prateek Sharma, Hannah K.B. Easton, Tzvetelin T. Dessev, Mita Lad, Peter A. Munro

Nutrition, Dietetics, and Food Sciences Faculty Publications

We explored anisotropy of mozzarella cheese: its presence is debated in the literature. Tensile testing proved a good method because the location and mode of failure were clear. Mozzarella cheese cut direct from the block showed no significant anisotropy, though confocal microscopy showed good structure alignment at a microscale. Deliberately elongated mozzarella cheese showed strong anisotropy with tensile strength in the elongation or fibre direction ∼3.5× that perpendicular to the fibres. Temperature of elongation had a marked impact on anisotropy with maximum anisotropy after elongation at 70 °C. We suggest the disagreement on anisotropy in the literature is related to …

Information Literacy And The Flipped Classroom: Examining The Impact Of A One-Shot Flipped Class On Student Learning And Perceptions, Andrea Wilcox Brooks

Communications in Information Literacy

This article examines the flipped classroom approach in higher education and its use in one-shot information literacy instruction sessions. The author presents findings from a pilot study of student learning and student perceptions pertaining to flipped model IL instruction. Students from two sections of the same course participated in this study. One section received one-shot information literacy instruction using a flipped approach, while the other section received traditional one-shot instruction. No difference was found between the two groups on a pre- and post-test analysis; however, an analysis of students' final papers from the flipped section showed more bibliography citations to …

Tracing The History Of Grounded Theory Methodology: From Formation To Fragmentation, Méabh Kenny, Robert Fourie

The Qualitative Report

There are very few articles, which track the history of Grounded Theory (GT) methodology from its tentative conception to its present divisions. This journal article addresses the dearth by tracing the history of GT methodology from its conception in the 1960’s, discussing the context of its composition, character, and contribution. Subsequently, the article follows the maturation of GT which is characterised by a series of contentious and, at times, antagonistic academic debates. The crux of these debates centres on disputes over core tenets of GT and have resulted in three dominant and divergent configurations of the GT methodology: Classic, Straussian, …

Platinum Hollow Nanospheres With Different Sizes: Controllable Synthesis And Electrocatalytic Oxidation Toward Methanol, Xuan Lin, Mei-Qin Cheng, Zhong-Jin Shang, Ting Xiong, Xian-Tu Zhang, Wei Tian, Jian-Yun Lin, Qi-Ling Zhong, Bin Ren

Journal of Electrochemistry

The selenium (Se) templates and hollow platinum (Pthollow) nanospheres with different sizes were controllably synthesized by adjusting the concentration of sodium dodecyl sulphonate (SDSN) (CSDSN, μmol·L-1) which was used as a surfactant. Accordingly, the Pthollow nanospheres modified glassy carbon (GC) electrode (Pthollow/GC) was prepared. The morphology and composition of Pthollow nanospheres were characterized by scanning electron microscopy (SEM), transmission electron microscope (TEM), energy dispersive X-ray spectroscopy (EDX), high resolution transmission electron microscopy (HRTEM), selected area electron diffraction (SAED) and X-ray diffraction (XRD) techniques. The electrocatalytic activities of Pthollow/GC and electrodeposited Pt nanoparticles modified glassy carbon electrode (Ptnano/GC) toward methanol oxidation …

Comparison In Factors Affecting Electrochemical Properties Of Thermal-Reduced Graphene Oxide For Supercapacitors, Peng Xiao, Da-Hui Wang, Jun-Wei Lang

Journal of Electrochemistry

In this paper, thermal-reduced graphene oxide (T-RGO) materials are synthesized by modified Hummer’s method, followed by thermal reduction under argon atmosphere at different temperatures. Electrochemical investigations show that, for T-RGO electrodes, good electrical conductivity is necessary and the surface functional groups play more significant role than the specific surface area in determining the electrochemical capacitance. The T-RGO obtained at 900 °C (T-RGO900) with a relatively high Brunauer-Emmett-Teller (BET) surface area (314 m²·g^-1) and a high electrical conductivity (2421 S·m^-1) shows a low specific capacitance of 56 F·g^-1. In comparison, the T-RGO obtained …

Kinetics And Mechanism Of Acidic Electroless Ni-P Plating, Zhi-Hui Xie, Gang Yu

Journal of Electrochemistry

Electrochemical behaviors of electroless nickel (EN) plating in three systems, namely, cathodic, anodic and complete bath solutions were investigated by polarization methods. The curves in the complete baths were not entirely consistent with those expected from a combination of the anodic and cathodic polarization curves, which implies that the anodic and cathodic reactions of the EN plating are interdependent. The effects of concentration of nickel ions, hypophosphite and pH on the polarization parameter and deposition rate in a complete bath were also discussed and compared by performing electrochemical and gravimetrical measurements. Based on these variations in the deposition potential and …

Synthesis Of Namnpo4 By Spraying Drying-High Temperature Sintering And Its Electrochemical Performance, Xiao-Chen Lin, Xiao-Biao Wu, Xu Hou, Yong Yang

Journal of Electrochemistry

It is shown that the precursors are hollow spherical particles and the obtained product consists of micro-scaled secondary particles, which are composed of NaMnPO₄ nanocrystallites (tens of nanometres) and amorphous carbon networks. The ionic and electronic conductivities of NaMnPO₄ are both effectively enhanced with the help of this …

One-Step Synthesis Of Pani/Nihcf Hybrid Film Using Unipolar Pulse Electrodeposition And Its Electrocatalytic Reduction Performance For H2O2 Detection, Sen-Liang Liao, Xiu-Min Li, Xiao-Gang Hao, Yan-Hong Wang, Chun-Feng Xue, Yong-Hong Wang

Journal of Electrochemistry

Organic–inorganic hybrid films composed of polyaniline/nickel hexacyanoferrate (PANI/NiHCF) were fabricated on platinum substrates using unipolar pulse one-step electrodeposition. The deposition mechanism of hybrid film was proposed: Due to high potential of unipolar pulse electrodeposition, which avoided the reduction of Fe(CN)₆^3-, the films with high electrocatalytic property and “insoluble” form of NiHCF were achieved. The morphology and composition of PANI/NiHCF hybrid film were characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and Fourier transform infrared spectroscopy (FT-IR). The effect of pulse potential on the electrochemical performance of hybrid film was investigated in detail. Results showed that …

Direct Electrochemistry And Glucose Biosensing Of Glucose Oxidase-Gold Nanoparticles Composite Synthesized By Enzyme Method, Fang He, Xiao-Li Qin, Ying-Chun Fu, Chao Chen, Qing-Ji Xie, Shou-Zhuo Yao

Journal of Electrochemistry

Glucose oxidase (GOx)-gold nanoparticles (AuNPs) composite was synthesized by the one-pot enzyme reaction in the mixture solution of NaAuCl₄, GOx and glucose, and a Nafion/GOx-AuNPs/glassy carbon electrode was fabricated by the cast-coating method to examine the direct electrochemistry of GOx and the biosensing performance on this electrode. Such a GOx-AuNPs composite showed good direct-electrochemistry activity and bioactivity of GOx, probably because the enzyme-mediated AuNPs are close to the redox active centers of GOx. This enzyme electrode exhibited a linear amperometric response to glucose concentration (0.54 mmol·L^-1) at -0.4 V (vs. SCE), and a detection limit of …
