A Simple Character For Sex Differentiation Of Pupae And Pupil Exuviae Of The Dogwood Borer (Lepidoptera: Sesiidae), Tracy C. Leskey, J. Christopher Bergh

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The sex of dogwood borer pupae and pupal exuviae can be easily differentiated based on characteristics of the fused terminal abdominal segment. In males, it is composed of segments 8- 10 and has three distinct rows of posteriorly projecting spines. By contrast, in females, the fused terminal abdominal segment is composed of segments 7-10 and has four distinct rows of posteriorly projecting spines.

Upland Rice And Allelopathy, N. K. Fageria, V. C. Baligar

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Upland rice (Oryza sativa L.) is mainly grown in Asia, Africa and Latin America. Yield potential of upland rice is quite low and invariably this crop is subjected to many environmental stresses. Further, when upland rice is grown in monoculture for more than two to three years on the same land, allelopathy or autotoxicity is frequently reported. Allelopathy involves complex plant and plant chemical interactions. The level of phytotoxicity of allelochemicals is influenced by abiotic and biotic soil factors. Adopting suitable management strategies in crop rotation can reduce or eliminate allelochemicals phytotoxicity. Rice yields can be improved by growing …

Evolution As Learning Yields Hyperbolic Discounting, James Woods

Economics Faculty Publications and Presentations

Learning is modeled as an infection, which jumps from person to person. The rate of infection mimics individual discount rates and induces savings behavior on its own. It is shown that the apparent discount rate, the combination of the agents’ true discount rate and the infection rate, decreases over time and approaches the agents’ true discount rate. This decrease, known as hyperbolic discounting, is consistent with what is observed in psychology studies, while the limiting case, exponential discounting, is consistent with market level observations. This model closes the gap between individual and market level observations of discounting behavior without explicitly …

Development Of Targeted Strategies For Church Growth Within The Greater New York Conference Of Seventh-Day Adventists, Angel Jesus Rodriguez

Doctor of Ministry Projects

Problem

For the past twelve years the Greater New York Conference has been struggling to produce growth within the Caucasian sector and other indigenous people groups. The primary source of membership growth has been from immigrants. An analysis of the demographics retained of the Conference's geographical location, however, reveals that the majority of the people are second- and third-generation Caucasian, Black, Hispanic, and Asian Americans. These are the people who the Greater New York Conference has not been successfully evangelizing.

Method

In order to understand how churches grow, I surveyed pertinent literature on church growth. I implemented these strategies into …

Hosford-Abernethy Bicycle And Pedestrian Connections: An Alternative Routes Analysis Linking Se Clinton Street And The Eastbank Esplanade, Shannon Axtell, Evan Mackenzie, Brady Smith, Allison Wildman

Master of Urban and Regional Planning Workshop Projects

SE Clinton is a popular bicycle route for commuter, utilitarian and recreational bicyclists that fails to provide a safe and direct connection to the Eastbank Esplanade and downtown Portland. Furthermore, residents in the Hosford-Abernethy and Brooklyn neighborhoods do not have a safe bicycle and pedestrian connection to access the Eastbank Esplanade. This gap in the bicycle and pedestrian network must be removed to serve the needs of bicyclists and pedestrians.

This project presents four alternative bicycle and pedestrian routes that connect the Eastbank Esplanade and the SE Clinton bikeway through the Central Eastside Industrial District. Each alternative, with improvements, is …

On The Proper Motives Of Corporate Directors (Or, Why You Don't Want To Invite Homo Economicus To Join Your Board), Lynn A. Stout

Cornell Law Faculty Publications

One of the most important questions in corporate governance is how directors of public corporations can be motivated to serve the interests of the firm. Directors frequently hold only small stakes in the companies they manage. Moreover, a variety of legal rules and contractual arrangements insulate them from liability for business failures. Why then should we expect them to do a good job?

Conventional corporate scholarship has great difficulty wrestling with this question, in large part because conventional scholarship usually adopts the economist's assumption that directors are rational actors motivated purely by self-interest. This homo economicus model of behavior may …

A Mind To Blame: New Views On Involuntary Acts, Deborah W. Denno

Faculty Scholarship

This article examines the legal implications linked to recent scientific research on human consciousness. The article contends that groundbreaking revelations about consciousness expose the frailties of the criminal law's traditional dual dichotomies of conscious versus unconscious thought processes and voluntary versus involuntary acts. These binary doctrines have no valid scientific foundation and clash with other key criminal law defenses, primarily insanity. As a result, courts may adjudicate like individuals very differently based upon their (often unclear) understanding of these doctrines and the science that underlies them. This article proposes a compromise approach by recommending that the criminal law's concept of …

Exploring The Importance Of Incorporating The Visual And Creative Arts Into Elementary School Curriculum, Emily Mcdaniel

Capstone Projects and Master's Theses

The target audience that my capstone report has been written for consists of elementary administrators and elementary instructors that do not already see the importance of arts integration in curriculum, and, hence, do little to employ the arts in their classrooms beyond a few finger paintings and holiday decorations. The primary intention of my report is to convey to elementary administrators and elementary instructors the importance of incorporating the visual and creative arts into elementary curriculum. The secondary intention of my capstone report is to illustrate that arts integration can be done easily, provided that the instructor is willing to …

The Influence Of Slow Calcium-Activated Potassium Channels On Epileptiform Activity In A Neuronal Model Of Pyramidal Cells, Keun-Hang Susan Yang, Piotr J. Franaszczuk, Gregory K. Bergey

Mathematics, Physics, and Computer Science Faculty Articles and Research

An imbalance between excitation and inhibition can play an important role in the generation of epileptiform activity. Experimental evidence indicates that alterations of either synaptic activity or intrinsic membrane properties may contribute to this imbalance. The slow Ca2+ - activated K+ currents (sIAHP) limit neuronal firing rate and excitability and are therefore of great interest for their potential role in epileptogenesis. The sIAHP is found in both excitatory and inhibitory neurons, and its effect on these neurons can influence the network behavior. Simulations show that the increased excitability caused by reduction of inhibition by the sIAHP for inhibitory interneuron generates …

Morphological And Functional Characteristics Of Skeletal Muscle Fibers From Hormone-Replaced And Nonreplaced Postmenopausal Women, Todd Shoepe

Health and Human Sciences Faculty Works

We tested the hypothesis that cross-bridge mechanisms of contraction differed in early postmenopausal women who did or did not receive hormone replacement therapy (HRT). Vastus lateralis biopsies were obtained from 17 postmenopausal women (49-57 years old), 8 of whom were on HRT for the previous 24 ± 5 months and 9 of whom were never on HRT. Electrophoresis and enzyme histochemistry revealed that fiber myosin heavy chain (MHC) isoform distribution, the cross-sectional area (CSA) of slow and fast fibers, and the relative CSA occupied by each, were similar for HRT and non-HRT groups. Single permeabilized fibers containing type IIa MHC …

Examining Ethnic Faultlines In Groups: A Multimethod Study Of Demographic Alignment, Leadership Profiles, Coalition Formation, Intersubgroup Conflict And Group Outcomes, Katerina Bezrukova, Karen A. Jehn

Psychology

This study used multiple methods to examine the effects of group member demographic alignment on coalition formation, intersubgroup conflict, and individual and group level outcomes in common-goal groups. The study uses a 2 by 2 experimental design, crossing demographic alignment (alignment vs. no alignment) and group leadership profile (split leaders vs. no split) as between-subjects variables. Data from 5 types of measurement were used to analyze the effects of member alignment and leadership profiles. We distinguish between potential group faultlines (aligned demographic characteristics of members) and active group faultlines (members actually divide into subgroups based on the aligned demographic characteristics) …

Type Ii Collagen Differentially Degraded Epitopes Can Be Used To Monitor In Vitro And In Vivo Cartilage Degradation, Brian Roland Felice

Open Access Dissertations

Articular cartilage is comprised of resident chondrocytes interspersed throughout a complicated network of molecules called the cartilage extracellular matrix (ECM). The major component of articular cartilage ECM is type II collagen, which supplies the matrix with its characteristic tensile strength. In some forms of arthritis such as osteoarthritis (OA), type II collagen is uncontrollably destroyed ultimately leading to joint dysfunction. Type II collagen, the major collagen type found in articular cartilage, may account for 95% of the total collagen content of articular cartilage. The molecules implicated in the destruction of the ECM are a family of enzymes called matrix metalloproteinases …

Prevalence And Risk Factors Associated With Substance Use And Abuse By Rhode Island Health Care Professionals, George Anthony Kenna

Open Access Dissertations

The major goals of this study were to address: (1) some of the key gaps in knowledge that can best be investigated by simultaneously examining the epidemiologic prevalence of alcohol, tobacco and other substance use by dentists, nurses, pharmacists and physicians; (2) methodological shortcomings of previous healthcare professional surveys. The method consisted of a seven page mail-survey sent to a random sample of 697 Rhode Island healthcare professionals (HCPs) during 2002. After three waves of surveys, 479 usable surveys were returned (68.7% response). The results of this study suggest HCPs are at slightly higher risk to use prescription drugs than …

Self-Organization, Hierarchy, And Task Structure In Workgroups: An Empirical Study Of Complexity Theory, Matthew G. Paldy

Open Access Dissertations

Complexity theorists argue that an optimal organizational form results from the interactions of individual agents in the absence of an imposed management hierarchy (Anderson, 1999; Begun, 1994; Berreby, 1998; Coveney & Highfield, 1995; Guastello, 2002). There have been few empirical studies to support this claim. This research investigated the effects of self-organization and task interdependence types on group effectiveness and member satisfaction. Results show that groups allowed to self-organize had greater member satisfaction in sequential and reciprocal task structures, shorter task completion times in sequential task structures, and lower satisfaction in pooled task structures versus comparable groups with hierarchy imposed. …

Parenting The Child With Hypoplastic Left Heart Syndrome, Sandra Ruth Mott

Open Access Dissertations

What is it like to parent a child born with hypoplastic left heart syndrome (HLHS)? Until recently these children did not live beyond infancy so the question was mute. With the advent of new technologies and care these infants are surviving and thriving. However, they require intense care during their first few years of life. A literature search revealed many publications related to the infant's physical care before, during and between surgeries but little that addressed parenting expectations or concerns. To discover what it was like to be the parent of a child, who was living with a reconstructed heart, …

The Influence Of Cognitive Reserve On Neuropsychological Functioning After Coronary Artery Bypass Grafting, Susan Anne Legendre

Open Access Dissertations

Neuropsychological functioning is negatively affected in many individuals who undergo coronary artery bypass grafting (CABG). However, the degree and consistency of this impairment is variable. Research in the fields of Alzheimer's disease and HIV suggests that the impact of various assaults to the central nervous system may be mediated through some form of cognitive reserve. The concept of cognitive reserve (CR) is based on the hypothesis that an individual's genetic make-up or experiences acquired throughout life, such as educational and occupational attainment, provide a reserve which allows an individual to sustain greater cerebral injury before clinical presentation of dysfunction. The …

Bacterioplankton Seasonal Dynamics In Narragansett Bay, Andrew M. Staroscik

Open Access Dissertations

This thesis describes the seasonal dynamics of the bacterioplankton in the bay using a weekly sampling regime. Sampling occurred between September 1999 and June 2002. Over the entire sampling period, temperature ranged from −1.0 to 22.6°C and significant correlations of temperature on bacterial abundance and production (p < 0.05) highlight the strong seasonality of bacterial activity in the bay. No significant relationships were found between the bacterial bulk parameters and concentrations of chlorophyll a. Gross bacterial production at the mid-bay station was 237 g C m−2yr −1, roughly 94% of previously reported estimates of bay-wide net phytoplankton primary production, indicating the importance of bacterial activity to the carbon budget of the bay. Denaturing gradient gel electrophoresis was used to observe bacterial community structure during two successive winter-spring periods. Each sample (n = 48) contained 10 to 32 discernable bands (phylotypes). Eight to 14 phylotypes appeared to be present in all or almost all of the samples collected in each year and many were present in both years. Others could be grouped into winter, early spring, late spring, and summer phylotypes based upon the temporal pattern of their presence/absence within the sample set. Temperature alone appears to be a poor indicator of the timing of transitions in bacterial community structure. Distinct transitions did coincide with changes in phytoplankton community structure, suggesting that the bacterial community changes in response to changes in phytoplankton activity and community composition. Bay-wide sampling showed that between 47 and 63% of the phylotypes present on each date were present at every location sampled indicating that about half of the dominant phylotypes in the bay have wide distributions. Sequencing results suggest that at least some of the ubiquitous members of the bacterioplankton community are related to previously cultured groups (α and γ Proteobacteria and Flavobacteriacea).

Nonenzymatic Formation Of Advanced Glycation Endproducts By Glucosamine Autocondensation And Glucosamine With Proteins, Xinfeng Zhang

Open Access Dissertations

Advanced glycation endproducts (AGE) are a complex and heterogeneous group of compounds formed mainly by the nonenzymatic reactions of reducing sugars with amino acids and proteins. AGE accumulate in plasma and tissues with aging, diabetes, and renal failure. Glucosamine (GlcN) nonenzymatically forms autocondensation glycation products under physiological conditions. Many studies have reported the effectiveness of oral doses of glucosamine alone or in combination with the galactosamine containing chondroitin in treating osteoarthritis. However, none of these studies have considered whether it is the glucosamine itself and/or one or more of its autocondensation products which exerts this effect. Carnosine has been regarded …

Personalizing The School Environment: Teacher-Based Advisory Programs That Support Student Adjustment And Academic Outcomes, Caroline Johnson Caswell

Open Access Dissertations

This study attempts to look at middle school teacher-based advisory programs in sixteen states across the nation. Over 200 schools were surveyed with analyses from administrator, teacher, and student responses. Regression analyses were conducted on a hierarchical basis with respect to school location, advisory structure (length and duration of advisory programs), advisory practices (academic and career issues, parental contact, individual meetings with students, study hall projects, linkages to guidance and health, leadership, and adjustment and health issues), teacher attitudes (job role strain, job satisfaction, parental contact, burnout total, and school climate), and student experiences (anxiety, depression, recognition, school transition, teacher …

Elementary School Children's Stigmatization Of Children With Mental Illness, Yvonne M. Fausett

Open Access Dissertations

Stigmatization of those with mental illness, while well-researched among the adult population, has not received as much empirical attention in relation to children as the targets of stigmatization or as the perpetuators of stigmatization. It has been speculated in the adult literature that the stigmatization of adults with mental illness by other adults is a product of childhood socialization. This study seeks to investigate the developmental trajectory of stigmatization, beginning in childhood. To this end, the Children's Stigmatization Measure (CSM) was generated as a self-report measure consisting of 4 clinical vignettes (e.g., Anxiety, Attention Deficit-Hyperactivity Disorder, Depression, Normal), with 10 …

Writing Across Cultures: Contrastive Rhetoric And A Writing Center Study Of One Student's Journey, Christine M. Fox

Open Access Dissertations

As student populations in colleges and universities continue to diversify, composition programs do not always meet students' varying needs. English as a Second Language (ESL) students appear to fail mainstream writing courses at higher rates than their traditional counterparts, yet mainstreaming continues to be mandated, often due to budgetary constraints. Many programs offer multicultural writing courses, but these, too, are often ineffective for many students. Meanwhile, as Paul Kei Matsuda shows, there is a decided split between the disciplines of composition and ESL. Since ESL scholars have a much stronger history of working with diverse student populations than composition scholars …

Computerized Behavioral Observation: Implications For Improving Accuracy And Reducing Bias, Charles Sicotte

Open Access Dissertations

Direct observation of behavior is a form of behavioral assessment that maintains a low level of inference when applied to psychoeducational decision-making. The recent proliferation of computer behavior-observation systems has provided observers with an efficient means for collecting direct behavior observational data (Kahng & Iwata, 2000; Shapiro & Kratochwill, 2000a, 2000b). Although computerized methods are less cumbersome than other recording methods (e.g., partial-interval form, narrative recording), it is not clear if computerized methods offer improvement by enhancing observational accuracy or reducing judgment bias that is generally initiated in applied settings (e.g. referral information; Arkes & Harkness, 1980; O'Reilly, Northcraft, & …
