Searching For Threshold Shifts In Spawner–Recruit Data, James E. Garvey, Russell A. Wright, Elizabeth A. Marschall

Publications

Relationships between spawning fish (S) and surviving offspring (recruits, R) are typically assumed to be continuous and nonlinear. However, R may change abruptly with small changes in S if population-, community-, or ecosystem-scale processes trigger low adult reproduction and cause populations to shift abruptly to regimes of low recruitment. We simulated R with low mean and variation below a known S threshold and high mean and variation of R above it. We compared simulations with published S–R relationships. For all data, we fit a conventional Ricker-type S–R model, a logistic depensatory model, and also searched for an …

Habitat Characteristics Of Black Crappie Nest Sites In An Illinois Impoundment, Quinton E. Phelps, Adam M. Lohmeyer, Nicholas C. Wahl, John M. Zeigler, Gregory W. Whitledge

Publications

Ten nest colonies of black crappie Pomoxis nigromaculatus were visually located and verified by angling in Campus Lake, a small urban impoundment in southern Illinois. Habitat characteristics were measured at these nest sites and compared to habitat measurements obtained from 45 unused sites. Seven habitat characteristics (substrate firmness, temperature, dissolved oxygen, distance to deep water [3.8-m depth contour], substrate type, vegetation height, and vegetation density) were significantly different between nest sites and unused sites. Although temperature and dissolved oxygen were significantly different between nest sites and unused sites, all values were within the suitable range for black crappie spawning to …

Biological Control Of Marmara Gulosa Guillén And Davis In The San Joaquin Valley, Crystal A. Kirkland

Master's Theses

Peelminer, Marmara gulosa Davis and Guillén, has been reported as a sporadic pest in California and Arizona since 1998. Marmara gulosa has been a persistent pest in the San Joaquin Valley of California (USA) since 1998. Prior to 2000 the only reports of high populations of citrus peelminer were in the Coachella Valley. The larval stages of M. gulosa create serpentine mines scarring the upper epidermal layers of citrus rind, rendering it unacceptable for fresh market sale. Chemicals have failed to provide adequate control of M. gulosa; thus, the use of natural enemies is considered the best long-term option. …

Kinematic Analysis Of Articulatory Coupling In Acquired Apraxia Of Speech Post-Stroke, Carly J. Bartle-Meyer, Justine V. Goozée, Bruce E. Murdoch, Jordan R. Green

Department of Special Education and Communication Disorders: Faculty Publications

Primary objective: Electromagnetic articulography was employed to investigate the strength of articulatory coupling and hence the degree of functional movement independence between individual articulators in apraxia of speech (AOS). Methods and procedures: Tongue-tip, tongue-back and jaw movement was recorded from five speakers with AOS and a concomitant aphasia (M = 53.6 years; SD = 12.60) during /ta, sa, la, ka/ syllable repetitions, spoken at typical and fastrates of speech. Covariance values were calculated for each articulatory pair to gauge the strength of articulatory coupling. The results obtained for each of the participants with AOS were individually compared to those obtained …

Judging Vanessa: Norm Setting And Deviance In The Law Of Motherhood, Michelle Oberman

William & Mary Journal of Race, Gender, and Social Justice

This article, by an author who has devoted over a decade to the study of women whom the law deems "bad" mothers, undertakes a more probing consideration of what truly separates the deviant mother from the "good" mother. In this article, she exposes the flaws in a binary classification of mothers as either "good" or "bad." She accomplishes this task by juxtaposing the stories, both legal and personal, of Vanessa, a woman whom society has judged to be a "bad" mother, and the author, a mother most in society would view as "good." In the end, the author not only …

Kairos And Safe Havens: The Timing And Calamity Of Unwanted Birth, Susan Ayres

William & Mary Journal of Race, Gender, and Social Justice

It is impossible to know the number of infants killed or illegally abandoned at birth. No official reporting requirements exist, but conservative estimates claim that in the United States, 150-300 infants are killed within twenty-four hours of life and that over 100 infants are illegally abandoned. Beginning in 1999, in an effort to stem the problem of neonaticide and illegal abandonment, states began enacting laws to legalize abandonment. By 2008, all fifty states had enacted safe haven laws, which allow parents to anonymously abandon newborns by delivering them to designated providers, such as hospitals. This article provides a practical and …

Rhetoric Versus Reality: The Jurisdiction Of Rape, The Indian Child Welfare Act, And The Struggle For Tribal Self-Determination, Maire Corcoran

William & Mary Journal of Race, Gender, and Social Justice

This note examines the rape crisis affecting Native American women today and the jurisdictional issues that affect how and whether tribes may prosecute and punish rapists. This note also examines the efficacy of the Indian Child Welfare Act (ICWA) in preventing inappropriate removal of Native children from their tribal environment. A comparison of these two subjects reveals that, although tribes are theoretically experiencing an era of tribal "self-determination," federal Indian law and policy, both old and new, continue to prevent tribes from achieving health and independence. Ultimately, the note concludes that a true solution to the problems affecting tribes can …

Female Investors And Securities Fraud: Is The Reasonable Investor A Woman?, Joan Macleod Heminway

William & Mary Journal of Race, Gender, and Social Justice

Let's face it. Women and men are different in more than just the biological sense. These differences play themselves out in a variety of contexts. Some of them are meaningful in theory or in reality; others are not.

Given an increase in women's involvement in business and finance, it is unsurprising that a multidisciplinary literature is emerging at the intersection of sex or gender differences and corporate governance. Much of the work in this area has centered on women and boards of directors and women in the executive ranks. However, it is important to focus on women not only as …

When Gender Meets Sex: An Exploratory Study Of Women Who Seduce Adolescent Boys, Kay L. Levine

William & Mary Journal of Race, Gender, and Social Justice

This article describes the origins, design, and implications of a new study exploring female-perpetrated statutory rape against adolescent boys in the United States. In contrast to both legal frameworks, which typically regard statutory rape as a male-on-female phenomenon, and existing literature from the fields of psychology and psychiatry derived from clinical samples and sex offender registries, this study examines the incidence of female-perpetrated statutory rape using data from electronic news reports covering the period 1990-2008. In this short article, the author explains the advantages of her approach over those taken by prior scholars, in terms of the size of the …

Networks Of Heightened Scrutiny In Corporate Law, Reza Dibadj

San Diego Law Review

This Article is a follow-up to a previous article, Networks of Fairness Review in Corporate Law (Fairness). After an overview of the fundamentals of the fairness standard and network theory, Fairness deployed network and statistical analyses to conduct an empirical study of the fairness doctrine as articulated by the Delaware Supreme Court and the Delaware Court of Chancery. This initial analysis focused on the fairness standard for one principal reason: it is considered to be the most plaintiff-friendly standard of review, in marked distinction to the well-known business judgment rule (BJR). But there are also four other prominent standards of …

A Lot About A Little Dot - Lessons Learned From Drosophila Melanogaster Chromosome 4, Nicole Riddle, Christopher Shaffer, Sarah C.R. Elgin

Biology Faculty Research

The fourth chromosome of Drosophila melanogaster has a number of unique properties that make it a convenient model for the study of chromatin structure. Only 4.2 Mb overall, the 1.2 Mb distal arm of chromosome 4 seen in polytene chromosomes combines characteristics of heterochromatin and euchromatin. This domain has a repeat density of ~35%, comparable to some pericentric chromosome regions, while maintaining a gene density similar to that of the other euchromatic chromosome arms. Studies of position-effect variegation have revealed that heterochromatic and euchromatic domains are interspersed on chromosome 4, and both cytological and biochemical studies have demonstrated that chromosome …

Acquired Appetitive Responding To Intravenous Nicotine Reflects A Pavlovian Conditioned Association, Jennifer E. Murray, Rick A. Bevins

Department of Psychology: Faculty Publications

Recent research examining Pavlovian appetitive conditioning has extended the associative properties of nicotine from the unconditioned stimulus or reward to include the role of a conditional stimulus (CS), capable of acquiring the ability to evoke a conditioned response. To date, published research has used presession extravascular injections to examine nicotine as a contextual CS in that appetitive Pavlovian drug discrimination task. Two studies in the current research examined whether a nicotine CS can function discretely, multiple times within a session using passive iv infusions. In Experiment 1, rats readily acquired a discrimination in conditioned responding between nicotine and saline infusions …

Endothelial Progenitor Cell Number And Colony-Forming Capacity In Overweight And Obese Adults, O J Maceneaney, E J Kushner, Gary P. Van Guilder, J J Greiner, B L Stauffer, C A Desouza

Health and Nutritional Sciences Faculty Publications

OBJECTIVE: To investigate whether adiposity influences endothelial progenitor cell (EPC) number and colony-forming capacity.
DESIGN: Cross-sectional study of normal weight, overweight and obese adult humans.
PARTICIPANTS: Sixty-seven sedentary adults (aged 45-65 years): 25 normal weight (body mass index (BMI) or=30 kg/m(2); 18 males/6 females). All participants were non-smokers and free of overt cardiometabolic disease.
MEASUREMENTS: Peripheral blood samples were collected and circulating EPC number was assessed by flow cytometry. Putative EPCs were defined as CD45(-)/CD34(+)/VEGFR-2(+)/CD133(+) or CD45(-)/CD34(+) cells. EPC colony-forming capacity was measured in vitro using a colony-forming unit (CFU) assay.
RESULTS: Number of circulating putative EPCs (either CD45(-)/CD34(+)/VEGFR-2(+)/CD133(+) or …

The Future (Or Lack Of Future) Of Personalized Prescription In Psychiatry, Jose De Leon

Psychiatry Faculty Publications

Rapid technological advances in genetics have created conceptual chaos regarding the genetics of drug response. Terms for differing concepts are used interchangeably: pharmacogenetics with pharmacogenomics, personalized medicine with personalized prescription. Biomarker has many definitions. The author prefers the concept of personalized prescription and uses it with implications beyond pharmacogenetics by considering all scientific information valid for prescribing medication. Genetics may not be crucial for all drugs. In this comprehensive view, clinicians must consider genetic, environmental and personal variables when prescribing medication and incorporate some basic pharmacological principles: (1) safety and efficacy, (2) pharmacokinetics and pharmacodynamics, (3) therapeutic window and prescriber's …

The Global Text Project, Richard T. Watson, Donald J. Mccubbrey

The African Journal of Information Systems

The Global Text Project is intended to create global free textbooks for students in the developing countries. We argue that two key technological and social developments offer an opportunity to create a new model for textbook publishing. First, the Internet is a low cost channel for distributing information products in digital form. Second, global digital communities have created the platform for collaborative creation of content. Through this model a free and open content library will be developed for students covering all major subjects for an undergraduate education. This project is a contributory measure to the global efforts to address the …

Genome-Wide Identification Of H-Ns-Controlled, Temperature-Regulated Genes In Escherichiacoli K-12, Christine A. White-Ziegler, Talya R. Davis

Biological Sciences: Faculty Publications

DNA microarrays demonstrate that H-NS controls 69% of the temperature regulated genes in Escherichia coli K-12. H-NS is shown to be a common regulator of multiple iron and other nutrient acquisition systems preferentially expressed at 37°C and of general stress response, biofilm formation, and cold shock genes highly expressed at 23°C.

Probing Single-Molecule Interfacial Electron Transfer Dynamics Of Porphyrin On Tio2 Nanoparticles, Yuanmin Wang, Xuefei Wang, Sujit Kumar Ghosh, H. Peter Lu

Chemistry Faculty Publications

Single-molecule interfacial electron transfer (ET) dynamics has been studied by using single-molecule fluorescence spectroscopy and microscopic imaging. For a single-molecule zinc-tetra (4-carboxyphenyl) porphyrin (ZnTCPP)/TiO2 nanoparticle system, the single-molecule fluorescence trajectories show strong fluctuation and blinking between bright and dark states. The intermittency and fluctuation of the single-molecule fluorescence are attributed to the variation of the reactivity of interfacial electron transfer. The nonexponential autocorrelation function and the power-law distribution of the probability density of dark times imply the dynamic and static inhomogeneities of the interfacial ET dynamics. On the basis of the power-law analysis, the variation of single-molecule interfacial ET reactivity …

Molecular Coevolution Of Pacific Northwest Hantaviruses And Their Host, The Deer Mouse, Peromyscus Maniculatus, Philip Darren Jones

Dissertations and Theses

Sin Nombre virus (SNV, family Bunyaviridae, genus Hantavirus), hosted by the deer mouse, Peromyscus maniculatus (family Cricetidae, Subfamily Neotominae), is the primary etiological agent of Hantavirus pulmonary syndrome (HPS) in the western United States. HPS, with known pathogenicity only to humans and for which there is no cure or prophylaxis, affects the epithelium of the lungs by making the capillaries leaky, thereby resulting in bilateral infiltrates, and eventually leading to respiratory failure and death by drowning in approximately 38% of hospitalized patients.

In the Americas, Peromyscus has been co-evolving with hantaviruses for approximately 12–20 million years, since the first …

El Azufre En Los Granos De Destilería Para El Ganado Lechero, D. Schingoethe, A. Garcia, K. Kalscheur, A. Hippen

SDSU Extension Extra Archives

El azufre es un elemento esencial que los animales necesitan para muchas funciones. Cerca del 0.15% del peso corporal es azufre. Se encuentra en los aminoácidos metioni¬na, cisteína, cistina, homocisteína y taurina; en el condroi¬tin sulfato del cartílago y en las vitaminas del complejo B tiamina y biotina. La metionina, tiamina y biotina no pueden sintetizarse en los tejidos del ganado, deben por lo tanto ser suministradas con la dieta o sintetizadas por los microorgan¬ismos del rumen. El contenido en azufre de la mayor parte de los alimentos refleja el contenido en aminoácidos azufrados de sus proteínas. En la tabla …

Line Edge Detection And Characterization In Sem Images Using Wavelets, Wei Sun, Jose A. Romagnoli, Joseph W. Tringe, Sonia E. Létant, Pieter Stroeve, Ahmet Palazoglu

Faculty Publications

Edge characterization has become increasingly important in nanotechnology due to the growing demand for precise nanoscale structure fabrication and assembly. Edge detection is often performed by thresholding the spatial information of a top-down image obtained by scanning electron microscopy or other surface characterization techniques. Results are highly dependent on an arbitrary threshold value, which makes it difficult to reveal the nature of the real surface and to compare results among images. In this paper, we present an alternative edge boundary detection technique based on the wavelet framework. Our results indicate that the method facilitates nanoscale edge detection and characterization by …
