Confessing The Secrets Of Others: Pascale Petit’S Poetic Employment Of Latin American Cultures And The Mexican Artist, Frida Kahlo, Zoë Brigley Mar 2008

Confessing The Secrets Of Others: Pascale Petit’S Poetic Employment Of Latin American Cultures And The Mexican Artist, Frida Kahlo, Zoë Brigley

Journal of International Women's Studies

This essay works to review the poetry of the Welsh-French writer Pascale Petit through the lens of recent theoretical scholarship relating to women, violence, and confession. More specifically, through a detailed analysis of two of her collections, The Zoo Father (2001) and The Wounded Deer (2005), I examine the ways in which Petit attempts to extricate confessional poetry from the stereotype of self-indulgent, ‘awful’ femininity outlined by Deryn Rees-Jones in Consorting with Angels (2005). It is my view that by recapitulating stories of women and violence in a variety of new contexts, Petit is able to reconfigure the politics of …

The Colonel's Finest Campaign: Robert R. Mccormick And Near V. Minnesota, Eric Easton Mar 2008

The Colonel's Finest Campaign: Robert R. Mccormick And Near V. Minnesota, Eric Easton

All Faculty Scholarship

Today, media corporations and their professional and trade associations, along with organizations like Reporters Committee for Freedom of the Press and the American Civil Liberties Union, carefully monitor litigation that implicates First Amendment values and decide whether, when, and how to intervene. It was not always so. Litigation by an institutional press to avoid or create doctrinal precedent under the First Amendment really began with the appointment of Col. Robert R. McCormick to head the ANPA's Committee on Freedom of the Press in the spring of 1928 and his involvement in Near v. Minnesota beginning that fall. Because of McCormick's …


A Songbird Forebrain Area Potentially Involved In Auditory Discrimination And Memory Formation, Raphael Pinaud, Thomas A. Terleph Mar 2008

A Songbird Forebrain Area Potentially Involved In Auditory Discrimination And Memory Formation, Raphael Pinaud, Thomas A. Terleph

Biology Faculty Publications

Songbirds rely on auditory processing of natural communication signals for a number of social behaviors, including mate selection, individual recognition and the rare behavior of vocal learning - the ability to learn vocalizations through imitation of an adult model, rather than by instinct. Like mammals, songbirds possess a set of interconnected ascending and descending auditory brain pathways that process acoustic information and that are presumably involved in the perceptual processing of vocal communication signals. Most auditory areas studied to date are located in the caudomedial forebrain of the songbird and include the thalamo-recipient field L (subfields L1, L2 and L3), …


Memory For Emotional Images : Recognition And Temporal Contexts, George E. Devore Mar 2008

Memory For Emotional Images : Recognition And Temporal Contexts, George E. Devore

Loma Linda University Electronic Theses, Dissertations & Projects

Negative emotional stimuli are usually better remembered than neutral emotional stimuli. Previous examination of binding theory found no differences in recall for homogeneous lists of taboo and neutral words. The current study expands on binding theory using negative and neutral visual stimuli in homogeneous lists. A rapid serial visual presentation paradigm and recognition and temporal memory item-discrimination tasks were used. Binding theory predicts no differences between negative and neutral images for recognition and temporal memory. Results were consistent with the assumptions of binding theory and no significant differences were found. This result suggests that binding theory generalizes for visual stimuli …

All Peer-Reviewed Publications

Five populations of the crambid stemborer Chilo partellus (Swinhoe) and one of the noctuid borer Busseola fusca (Fuller) from Zimbabwe were evaluated for their suitability for immature development of the exotic braconid larval parasitoid Cotesia flavipes Cameron. Successful parasitoid development occurred only on C. partellus but parasitism as well as egg-to-adult development time did not vary among the five populations. Smallest parasitoid broods, and sex ratios as the proportion of female offspring, however, were produced with C. partellus from the Muzarabani area of Zimbabwe. Co. flavipes became successfully established in five out of eight locations, where it had been released …

Cryo-Electron Tomography Of Kaposi's Sarcoma-Associated Herpesvirus Capsids Reveals Dynamic Scaffolding Structures Essential To Capsid Assembly And Maturation, Binbin Deng, Christine M O'Connor, Dean H Kedes, Z Hong Zhou

Faculty, Staff and Student Publications

Kaposi's sarcoma-associated herpesvirus (KSHV) is a recently discovered DNA tumor virus that belongs to the gamma-herpesvirus subfamily. Though numerous studies on KSHV and other herpesviruses, in general, have revealed much about their multilayered organization and capsid structure, the herpesvirus capsid assembly and maturation pathway remains poorly understood. Structural variability or irregularity of the capsid internal scaffolding core and the lack of adequate tools to study such structures have presented major hurdles to earlier investigations employing more traditional cryo-electron microscopy (cryoEM) single particle reconstruction. In this study, we used cryo-electron tomography (cryoET) to obtain 3D reconstructions of individual KSHV capsids, allowing …

Particle Swarm Optimization: Basic Concepts, Variants And Applications In Power Systems, Yamille Del Valle, Ganesh K. Venayagamoorthy, Salman Mohagheghi, Ronald G. Harley, J. C. Hernandez

Electrical and Computer Engineering Faculty Research & Creative Works

Many areas in power systems require solving one or more nonlinear optimization problems. While analytical methods might suffer from slow convergence and the curse of dimensionality, heuristics-based swarm intelligence can be an efficient alternative. Particle swarm optimization (PSO), part of the swarm intelligence family, is known to effectively solve large-scale nonlinear optimization problems. This paper presents a detailed overview of the basic concepts of PSO and its variants. Also, it provides a comprehensive survey on the power system applications that have benefited from the powerful nature of PSO as an optimization technique. For each application, technical details that are required …


Computational Models Of Tandem Src Homology 2 Domain Interactions And Application To Phosphoinositide 3-Kinase, Dipak Barua, James R. Faeder, Jason M. Haugh Mar 2008

Computational Models Of Tandem Src Homology 2 Domain Interactions And Application To Phosphoinositide 3-Kinase, Dipak Barua, James R. Faeder, Jason M. Haugh

Chemical and Biochemical Engineering Faculty Research & Creative Works

Intracellular signal transduction proteins typically utilize multiple interaction domains for proper targeting, and thus a broad diversity of distinct signaling complexes may be assembled. Considering the coordination of only two such domains, as in tandem Src homology 2 (SH2) domain constructs, gives rise to a kinetic scheme that is not adequately described by simple models used routinely to interpret in vitro binding measurements. To analyze the interactions between tandem SH2 domains and bisphosphorylated peptides, we formulated detailed kinetic models and applied them to the phosphoinositide 3-kinase p85 regulatory subunit/platelet-derived growth factor β-receptor system. Data for this system from different in …


Geographic Variation In Adult Survival And Reproductive Tactics Of The Mosquito Aedes Albopictus, Paul T. Leisnham, L M. Sala, Steven A. Juliano Mar 2008

Geographic Variation In Adult Survival And Reproductive Tactics Of The Mosquito Aedes Albopictus, Paul T. Leisnham, L M. Sala, Steven A. Juliano

Faculty Publications – Biological Sciences

Climate differences across latitude can result in seasonal constraints and selection on life history characters. Since Aedes albopictus (Skuse) invaded North America in the mid-1980s, it has spread across a range of approximate to 14 degrees latitude and populations in the north experience complete adult mortality due to cold winter temperatures that are absent in the south. Life table experiments were conducted to test for differences in the adult survival and reproductive schedules of Ae. albopictus females from two populations from the northern (Bloomington, IN [BL] and Manassas, VA [VA]; approximate to 39 degrees N) and southern (Tampa, FL and …


Speaking Out: The Responsibilities Of Management Intellectuals: A Survey, Stephen Dunne, Stefano Harney, Martin Parker Mar 2008

Speaking Out: The Responsibilities Of Management Intellectuals: A Survey, Stephen Dunne, Stefano Harney, Martin Parker

Research Collection Lee Kong Chian School Of Business

This article discusses our analysis of over 2,000 articles publishedwithin 20 top business and management journals. The article empirically demonstrates how little attention is being paid by the work published within these journals to contemporary political issues across the globe. We also demonstrate the extent to which the same is true of ‘critical’ journals such as Organization. To this end we argue that mass scholarly ranking mechanisms, such as the British Research Assessment Exercise (RAE),create a general state of myopia on the part of business and management scholars towards a variety of political issues, even making a virtue out of …

PURPOSE: To describe how investigators in a multisite randomized clinical trial addressed scientific and ethical issues involved in creating risk models based on genetic testing for African American participants. METHODS: The following informed our decision whether to stratify risk assessment by ethnicity: evaluation of epidemiological data, appraisal of benefits and risks of incorporating ethnicity into calculations, and feasibility of creating ethnicity-specific risk curves. Once the decision was made, risk curves were created based on data from a large, diverse study of first-degree relatives of patients with Alzheimer disease. RESULTS: Review of epidemiological data suggested notable differences in risk between African …


The Business Ethics According To Management Theory, Saad Ali Al-Anzi Mar 2008

The Business Ethics According To Management Theory, Saad Ali Al-Anzi

Journal of Economics and Administrative Sciences

The paper explores the critical evolution and integration of ethical principles within the framework of modern management practices. It examines how management theories have historically addressed—or neglected—the moral dimensions of organizational behavior, highlighting the shift from purely profit-oriented motives to a more holistic approach that incorporates social responsibility and stakeholder interests. The study argues that ethical conduct is not merely a legal or peripheral requirement but a fundamental pillar of sustainable organizational success and effective leadership. By analyzing various schools of management thought, the author demonstrates the intersection between strategic decision-making and ethical integrity, suggesting that long-term corporate viability depends …

Chemistry Faculty Publications and Presentations

Novel fluorescent chiral molecular micelles (FCMMs) were synthesized, characterized, and employed as chiral selectors for enantiomeric recognition of non-fluorescent chiral molecules using steady state fluorescence spectroscopy. The sensitivity of the fluorescence technique allowed for investigation of low concentrations of chiral selector (3.0 x 10(-5) M) and analyte (5.0 x 10(-6) M) to be used in these studies. The chiral interactions of glucose, tartaric acid, and serine in the presence of FCMMs poly(sodium N-undecanoyl-L-tryptophanate) [poly-L-SUW], poly(sodium N-undecanoyl-L-tyrosinate) [poly-L-SUY], and poly(sodium N-undecanoyl-L-phenylalininate) [poly-SUF] were based on diastereomeric complex formation. Poly-L-SUW had a significant fluorescence emission spectral difference as compared to poly-L-SUY and …

Cancer poses a tremendous therapeutic challenge worldwide, highlighting the critical need for developing novel therapeutics. A promising cancer treatment modality is gene therapy, which is a form of molecular medicine designed to introduce into target cells genetic material with therapeutic intent. Anticancer gene therapy strategies currently used in preclinical models, and in some cases in the clinic, include proapoptotic genes, oncolytic/replicative vectors, conditional cytotoxic approaches, inhibition of angiogenesis, inhibition of growth factor signaling, inactivation of oncogenes, inhibition of tumor invasion and stimulation of the immune system. The translation of these novel therapeutic modalities from the preclinical setting to the clinic …

Stress response pathways allow cells to sense and respond to environmental changes and adverse pathophysiological states. Pharmacological modulation of cellular stress pathways has implications in the treatment of human diseases, including neurodegenerative disorders, cardiovascular disease, and cancer. The quinone methide triterpene celastrol, derived from a traditional Chinese medicinal herb, has numerous pharmacological properties, and it is a potent activator of the mammalian heat shock transcription factor HSF1. However, its mode of action and spectrum of cellular targets are poorly understood. We show here that celastrol activates Hsf1 in Saccharomyces cerevisiae at a similar effective concentration seen in mammalian cells. Transcriptional …

Faculty, Staff and Student Publications

Gammaherpesviruses, including the human pathogens Epstein-Barr virus and Kaposi's sarcoma-associated herpesvirus, are causative agents of lymphomas and other malignancies. The structural characterization of these viruses has been limited due to difficulties in obtaining adequate amount of virion particles. Here we report the first three-dimensional structural characterization of a whole gammaherpesvirus virion by an emerging integrated approach of cryo-electron tomography combined with single-particle cryo-electron microscopy, using murine gammaherpesvirus-68 (MHV-68) as a model system. We found that the MHV-68 virion consists of distinctive envelope and tegument compartments, and a highly conserved nucleocapsid. Two layers of tegument are identified: an inner tegument layer …

Automatic Drift Compensation Using Phase Correlation Method For Nanomanipulation, Qinmin Yang, Jagannathan Sarangapani, Eric W. Bohannan Mar 2008

Automatic Drift Compensation Using Phase Correlation Method For Nanomanipulation, Qinmin Yang, Jagannathan Sarangapani, Eric W. Bohannan

Electrical and Computer Engineering Faculty Research & Creative Works

Nanomanipulation and nanofabrication with an atomic force microscope (AFM) or other scanning probe microscope (SPM) are a precursor for nanomanufacturing. It is still a challenging task to accomplish nanomanipulation automatically. In ambient conditions without stringent environmental controls, the task of nanomanipulation requires extensive human intervention to compensate for the spatial uncertainties of the SPM. Among these uncertainties, the thermal drift, which affects spatial resolution, is especially hard to solve because it tends to increase with time, and cannot be compensated simultaneously by feedback from the instrument. In this paper, a novel automatic compensation scheme is introduced to measure and estimate …


Regulation Of Multiple Angiogenic Pathways By Dll4 And Notch In Human Umbilical Vein Endothelial Cells, Ls Harrington, Rca Sainson, Ck Williams, Jm Taylor, Et Al Mar 2008

Regulation Of Multiple Angiogenic Pathways By Dll4 And Notch In Human Umbilical Vein Endothelial Cells, Ls Harrington, Rca Sainson, Ck Williams, Jm Taylor, Et Al

School of Biomedical Sciences

The Notch ligand, Dll4, is essential for angiogenesis during embryonic vascular development and is involved in tumour angiogenesis. Several recent publications demonstrated that blockade of Dll4 signalling inhibits tumour growth, suggesting that it may constitute a good candidate for anti-cancer therapy. In order to understand the role of Dll4 at the cellular level, we performed an analysis of Dll4-regulated genes in HUVECs. The genes identified included several angiogenic signalling pathways, such as VEGF, FGF and HGF. In particular we identified downregulation (VEGFR2, placenta growth factor PlGF) of VEGF pathway components resulting in the overall effect of limiting the response of …

Effects Of Ionic Strength, Temperature, And Ph On Degradation Of Selected Antibiotics, Keith A. Loftin, Craig D. Adams, Michael T. Meyer, Rao Surampalli

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Aqueous degradation rates, which include hydrolysis and epimerization, for chlorretracycline (CTC), oxytetracycline (OTC), tetracycline (TET), lincomycin (LNC), sulfachlorpyridazine (SCP), sulfadimethoxine (SDM), sulfathiazole (STZ), trimethoprim (TRM), and tylosin a (TYL) were studied as a function of ionic strength (0.0015, 0.050, or 0.084 mg/L as Na2HPO4), temperature (7, 22, and 35°C), and pH (2, 5, 7, 9, and 11). Multiple linear regression revealed that ionic strength did not significantly affect (α = 0.05) degradation rates for all compounds, but temperature and pH affected rates for CTC, OTC, and TET significand (α = 0.05). Degradation also was observed for TYL at pH 2 …


Juror Comprehension And The Hard Case: Making Forensic Evidence Simpler, Mark Findlay Mar 2008

Juror Comprehension And The Hard Case: Making Forensic Evidence Simpler, Mark Findlay

Research Collection Yong Pung How School Of Law

The complexity/comprehension nexus as it impacts on juror decision-making is addressed in the particular context of prosecution-led DNA evidence. Such evidence is for jurors the subject of pre-trial preconceptions, and is notoriously difficult to present and argue before a jury. The article looks at the comprehension of forensic evidence by jurors, a task qualified by the opinion of legal professionals whose responsibility it is to present and interpret such evidence in adversarial contexts.Jurors were surveyed post-verdict in trials where forensic evidence featured in circumstantial cases. These insights into comprehension were qualified by contesting views of legal professionals, and critical reflections …

Gastric Corpus Polyps Associated With Proton Pump Inhibitors Therapy, Javed Yakoob, Zaigham Abbas, Wasim Jafri, Zubair Ahmad

Section of Gastroenterology

The prevalence of Gastroesophageal Reflux Disease (GERD) is rapidly rising in Asia. We describe here a case of 51 years old man who had surgery for esophageal leiomyoma and received long-term therapy with Proton Pump Inhibitors (PPIs) for persisting reflux symptoms. On Esophago-Gastroduodenoscopy (EGD) several sessile polyps were seen in the gastric corpus. Earlier EGD done 15 years back had not demonstrated those polyps. Sections revealed polypoid fragments of glandular epithelium with dilated glands and negative histology for H. pylori. Polymerase chain reaction for 16S ribosomal RNA gene (16S rRNA PCR) of H. pylori was also negative. This is the …


Physiological Characterization Of Stolon Regression In A Colonial Hydroid, Neil W. Blackstone, Kimberly S. Cherry Vogt, Gabrielle Geddes, Lori Bross Mar 2008

Physiological Characterization Of Stolon Regression In A Colonial Hydroid, Neil W. Blackstone, Kimberly S. Cherry Vogt, Gabrielle Geddes, Lori Bross

Faculty Articles, Papers, and Other Scholarship

As with many colonial animals, hydractiniid hydroids display a range of morphological variation. Sheet-like forms exhibit feeding polyps close together with short connecting stolons, whereas runner-like forms have more distant polyps and longer connecting stolons. These morphological patterns are thought to derive from rates of stolon growth and polyp formation. Here, stolon regression is identified and characterized as a potential process underlying this variation. Typically, regression can be observed in a few stolons of a normally growing colony. For detailed studies, many stolons of a colony can be induced to regress by pharmacological manipulations of reactive oxygen species (e.g. hydrogen …
