The Effect Of Vegetation And Water Depth On Nest Patterns Of The Eurasian Coot (Fulica Atra), Ali̇ Uzun

Turkish Journal of Zoology

Nest characteristics of the Eurasian coot (Fulica atra) and the effect of vegetation and water depth on nest size were investigated. The study was conducted in 2008 on Poyrazlar Lake (Sakarya) in northwest Turkey. Depth and distance from the edge has no effect on internal nest diameter; however, nest height and external diameter are correlated with water depth.

The Farnet Journey: Perceptions Of Māori Students Engaged In Secondary Online Learning, Carolyn Bennett, Michael Barbour

Education Faculty Publications

This case study investigated the perceptions of Māori students in the Virtual Learning Network of what constituted effective strategies for engaging them in online learning. In the FarNet cluster, about 63 students from the four secondary and five area schools access the VLN, and approximately 80 percent of those students are of Māori descent. Data collection included online surveys, semi-structured interviews, and observation of online classrooms. The data suggested there was a variety of delivery models experienced by students, most supported by the learning management system. Students identified a range of Web 2.0 strategies currently used by their e-teachers, and …

Can Professional Development Improve Teachers’ Perceptions About Inclusive Teaching In An Inner City School, Solomon Homidas

Abraham S. Fischler College of Education ETD Archive

This applied dissertation examined the question of whether professional development can improve teachers’ perceptions of inclusive teaching in an inner city school. The study drew upon survey methods to collect measurements of teachers' perceptions about inclusive teaching before and after professional development sessions. The hypothesis was that exposure to professional development would give teachers an improved impression of inclusive teaching, which in turn could make them more committed to the inclusive teaching paradigm. If the hypothesis was correct, the study would show that professional development should be considered an important component of developing teachers who work in inclusive settings, especially …

An Elementary-To-Middle School Transitional Program And Its Effect On Student Behavior, Kyle Sheer

Abraham S. Fischler College of Education ETD Archive

The transition from elementary to middle school has proven to be difficult for all stakeholders. Reports of increased discipline infractions and truancy, combined with a noticeable drop in overall student achievement, have resulted in numerous attempts to ease the anxieties and frustrations that are characteristic of this transition. Schools often establish transitional programs to prepare incoming middle school students with the skills needed to be successful in a new educational environment. Transitional programs are often very expensive to operate and require an extensive amount of planning. This program evaluation considered 1 specific transitional program that took place during the summer …

Applying Peer Modeling In Inclusion Classrooms: A Study On Educators’ Perception, Rossana I. Chiarella

Abraham S. Fischler College of Education ETD Archive

This study evaluated the effects of educators’ perception on the application of peer modeling strategies in the classrooms. Without teachers’ positive attitude towards peer modeling, it was difficult to apply these strategies effectively. Teachers’ attitudes were determined by their existing perceptions, whereas different perceptions resulted in different dispositions to act and different outcomes. The purpose was to determine how teachers in a school located in south Florida applied peer modeling, and how their perceptions over it played an important role. The researcher attempted to evaluate the importance of peer-model strategies and to demonstrate the true benefit of their proper application …

Generational Differences In Work Ethic: A Study Of Four Generations In The Workplace, Kathleen J. Barlow

Abraham S. Fischler College of Education ETD Archive

This purpose of this study was to examine the degree to which differences in work ethic existed among four generations and two genders in the workplace. Data from four subsets of the Multidimensional Work Ethic Profile (MWEP) were examined (delay of gratification, hard work, morality/ethics, and self-reliance). Popular press has raised awareness of differences in work ethic between generations; however, scholars have disagreed about whether generational differences existed in the workplace. The writer used archival data to examine the work ethic of four generations of workers.

Two research questions guided this study:

1. What differences in work ethic, if any, …

Carbon Isotope And Stomatal Data Of Late Pliocene Betulaceae Leaves From Sw China: Implications For Palaeoatmospheric Co2-Levels, Bainian Sun, Suting Ding, Jingyu Wu, Chong Dong, Sanping Xie, Zhicheng Lin

Turkish Journal of Earth Sciences

The cuticular \delta^1^3C values and stomatal parameters (stomatal density and stomatal index: SD and SI) of two Betulaceae species, Betula mioluminifera Hu et Chaney and Carpinus miofangiana Nathorst, from a suite of superposed horizons in West Yunnan, southwestern China, were measured in order to recover Late Pliocene CO2 levels. Correlations are given for \delta^1^3C, SD, epidermal cell density (ECD), and SI. \delta^1^3C reveals a positive trend with the SD and SI in the two species, and such a positive correlation can also be observed between the \delta^1^3C and ECD in C. miofangiana. However, \delta^1^3C has a slightly negative correlation with …

Gene Expression Profiling Of The Plant Pathogenic Basidiomycetous Fungus Rhizoctonia Solani Ag 4 Reveals Putative Virulence Factors, Dilip K. Lakshman, Nadim Alkharoud, Daniel P. Roberts, Savithiry S. Natarajan, Amitava Mitra

Department of Plant Pathology: Faculty Publications

Rhizoctonia solani is a ubiquitous basidiomycetous soilborne fungal pathogen causing damping- off of seedlings, aerial blights and postharvest diseases. To gain insight into the molecular mechanisms of pathogenesis a global approach based on analysis of expressed sequence tags (ESTs) was undertaken. To get broad gene-expression coverage, two normalized EST libraries were developed from mycelia grown under high nitrogen-induced virulent and low nitrogen/methylglucose-induced hypovirulent conditions. A pilot-scale assessment of gene diversity was made from the sequence analyses of the two libraries. A total of 2280 cDNA clones was sequenced that corresponded to 220 unique sequence sets or clusters (contigs) and 805 …

Effects Of Early Application Timing Of Foliar Fungicides In Field Corn In Central Nebraska, 2011, C. M. Schleicher, T. A. Jackson

Department of Plant Pathology: Faculty Publications

A foliar fungicide early application timing trial was conducted at the University of Nebraska-Lincoln South Central Agricultural Laboratory near Clay Center, NE. DeKalb corn hybrid DKC 62-54, rating of “good” (6 out of 9) for gray leaf spot (GLS) and “excellent” (2 out of 9) for common rust (CR), was planted on 3 May in 30 in. rows with a target population of 32,000 plants/A.

Disaster Mental Health, Denise Bulling, Tarik Abdel-Monem

University of Nebraska Public Policy Center: Publications

People have always given aid and comfort to each other during times of disaster. However, attempts to structure and professionalize this assistance are fairly recent developments. Disaster mental health, as an evolving field of practice and study, is a collection of interventions and practices that are designed to address incident-specific stress reactions, rather than ongoing or developmental mental health needs. Traditional mental health practice is based on a medical model, with a clinician seeing a patient in an office setting. Disaster mental health introduces a paradigm shift, requiring that practitioners (clinicians and indigenous helpers) work with individuals and whole communities …

Does The Reason Matter? Variations In Childlessness Concerns Among U.S. Women, Julia Mcquillan, Arthur L. Greil, Patricia Wonch Hill, Kari C. Gentzler, John D. Hathcoat

Department of Sociology: Faculty Publications

Does the reason why women have no children matter with regard to level of childlessness concerns? Reasons include biomedical barriers, situational barriers, delaying motherhood, and choosing to be childfree. The concept of ‘‘childlessness concerns’’ captures the idea that holidays and family gatherings are difficult because of not having children or feeling left out or sad that others have children. Life course and identity theories guided the structural equation model analyses of a representative sample of 1,180 U.S. women without children from the National Survey of Fertility Barriers. The results indicated that women with the least control over pregnancy, those with …

Department of Special Education and Communication Disorders: Faculty Publications

Objective—To measure and compare the perioral stiffness among three groups of pediatric subjects: a group of patients with a repaired cleft lip (and palate) who had a secondary lip revision surgery (revision), another group of patients with repaired cleft lip (and palate) who did not have secondary surgery (nonrevision), and a group of noncleft “normal” patients (noncleft).

Design—A parallel, three-group, nonrandomized clinical trial.

Participants—A total of 16 patients with repaired cleft lip/palate who did not have lip revision, 13 patients with repaired cleft lip/palate who had lip revision surgery and were tested at 18 to 24 months postsurgery, and 27 …

A Novel Fixed-Target Task To Determine Articulatory Speed Constraints In Persons With Amyotrophic Lateral Sclerosis, Antje Mefferd, Jordan R. Green, Gary L. Pattee

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: The goal of this study was to determine if talkers with ALS are limited in their ability to increase lower lip and jaw speed at an early stage of the disease when their speaking rate and intelligibility are only minimally or not affected.

Method: A novel metronome paced fixed-target task was used to assess movement speed capacities during lower lip and jaw oscillations in seven talkers with ALS and seven age and gender matched controls.

Results: Lower lip peak speeds were significantly lower in talkers with mild ALS than in healthy talkers suggesting a lower lip speed constraint in …

Estimating The Size Of The Methamphetamine-Using Population In New York City Using Network Sampling Techniques, Kirk Dombrowski, Bilal Khan, Travis Wendel, Katherine Mclean, Evan Misshula, Ric Curtis

Department of Sociology: Faculty Publications

As part of a recent study of the dynamics of the retail market for methamphetamine use in New York City, we used network sampling methods to estimate the size of the total networked population. This process involved sampling from respondents’ list of co-use contacts, which in turn became the basis for cap-ture-recapture estimation. Recapture sampling was based on links to other respondents derived from demographic and “telefunken” matching procedures–the latter being an anonymized version of telephone number matching. This paper describes the matching process used to discover the links between the solic-ited contacts and project respondents, the capture-recapture calculation, the …

Feasibility Of Integrating Natural And Constructed Wetlands In Roadway Drainage System Design, John S. Stansbury, Massom Moussavi, Tian Zhang

Mid-America Transportation Center: Final Reports and Technical Briefs

Stormwater from roadways could have negative effects on the environment and aquatic ecosystems. Typical highway runoff pollutants include solids; heavy metals, particularly cadmium, copper, and zinc; petroleum hydrocarbons; gasoline constituents; PAHs (polyaromatic hydrocarbons); oxygen demanding compounds measured as COD (chemical oxygen demand) and BOD (biochemical oxygen demand); and road salts. Roadway runoff falls under the legislation of the Clean Water Act (CWA) via the National Pollutant Discharge Elimination System (NPDES). CWA regulates discharge of nonpoint source pollutants, such as roadway runoff, by issuing permits to public entities which manage Municipal Separate Storm Sewer Systems (MS4s). Part of the Nebraska Department …

Modeling Stochasticity And Variability In Gene Regulatory Networks, David Murrugarra, Alan Veliz-Cuba, Boris Aguilar, Seda Arat, Reinhard Laubenbacher

Department of Mathematics: Faculty Publications

Modeling stochasticity in gene regulatory networks is an important and complex problem in molecular systems biology. To elucidate intrinsic noise, several modeling strategies such as the Gillespie algorithm have been used successfully. This article contributes an approach as an alternative to these classical settings. Within the discrete paradigm, where genes, proteins, and other molecular components of gene regulatory networks are modeled as discrete variables and are assigned as logical rules describing their regulation through interactions with other components. Stochasticity is modeled at the biological function level under the assumption that even if the expression levels of the input nodes of …

A Riverscape Perspective Of Pacific Salmonids And Aquatic Habitats Prior To Large-Scale Dam Removal In The Elwha River, Washington, Usa, S. J. Brenkman, Jeff J. Duda, Christian E. Torgersen, Ethan Welty, G.R. Pess, R. Peters, M.L. Mchenry

United States National Park Service: Publications

Dam removal has been increasingly proposed as a river restoration technique. In 2011, two large hydroelectric dams will be removed from Washington State’s Elwha River. Ten anadromous fish populations are expected to recolonise historical habitats after dam removal. A key to understanding watershed recolonisation is the collection of spatially continuous information on fish and aquatic habitats. A riverscape approach with an emphasis on biological data has rarely been applied in mid-sized, wilderness rivers, particularly in consecutive years prior to dam removal. Concurrent snorkel and habitat surveys were conducted from the headwaters to the mouth (rkm 65–0) of the Elwha River …

Habitat Fragmentation Effects On Annual Survival Of The Federally Protected Eastern Indigo Snake, D. R. Breininger, Marc J. Mazerolle, M. R. Bolt, M. L. Legare, J. H. Drese, J. E. Hines

United States National Aeronautics and Space Administration: Publications

The eastern indigo snake (Drymarchon couperi) is a federally listed species, most recently threatened by habitat loss and habitat degradation. In an effort to estimate snake survival, a total of 103 individuals (59 males, 44 females) were followed using radio-tracking from January 1998 to March 2004 in three landscape types that had increasing levels of habitat fragmentation: (1) conservation cores; (2) conservation areas along highways; (3) suburbs. Because of a large number of radio-tracking locations underground for which the state of snakes (i.e. alive or dead) could not be assessed, we employed a multistate approach to model snake …

Modeling The Spatial And Temporal Heterogeneity Of Deforestation-Driven Carbon Emissions: The Inpe-Em Framework Applied To The Brazilian Amazon, Ana Paula Dutra Aguiar, Jean Pierre Ometto, Carlos Nobre, David Montenegro Lapola, Claudio Almeida, Ima Célia Vieira, Joao Vianei Soares, Regina Alvala, Sassan Saatchi, Dalton Valeriano, Juan Carlos Castilla-Rubio

United States National Aeronautics and Space Administration: Publications

We present a generic spatially explicit modeling framework to estimate carbon emissions from deforestation (INPE-EM). The framework incorporates the temporal dynamics related to the deforestation process and accounts for the biophysical and socioeconomic heterogeneity of the region under study. We build an emission model for the Brazilian Amazon combining annual maps of new clearings, four maps of biomass, and a set of alternative parameters based on the recent literature. The most important results are as follows: (a) Using different biomass maps leads to large differences in estimates of emission; for the entire region of the Brazilian Amazon in the last …

Compact Two-Step Laser Time-Of-Flight Mass Spectrometer For In Situ Analyses Of Aromatic Organics On Planetary Missions, Stephanie A. Getty, William B. Brinckerhoff, Timothy Cornish, Scott Ecelberger, Melissa Floyd

United States National Aeronautics and Space Administration: Publications

RATIONALE: A miniature time-of-flight mass spectrometer measuring 20 cm in length has been adapted to demonstrate two-step laser desorption/ionization (LDI) in a compact instrument package for enhanced organics detection. Two-step LDI decouples the desorption and ionization processes, relative to traditional LDI, in order to produce low-fragmentation mass spectra of organic analytes. Tuning the UVionization laser energy would allow control of the degree of fragmentation, which might enable better identification of constituent species.

METHODS: A reflectron time-of-flight mass spectrometer prototype was modified to allow a two-laser configuration, with IR (1064 nm) desorption followed by UV (266 nm) postionization. A …

Remodeling Cross-Β Nanotube Surfaces With Peptide/Lipid Chimeras, Rong Ni, W. Seth Childers, Kenneth I. Hardcastle, Anil K. Mehta, David G. Lynn

United States National Aeronautics and Space Administration: Publications

Peptide/lipid chimeras, which are generally referred to as peptide amphiphiles, array specific peptides on the surface of ordered lipid assemblies.^[1] These materials are being explored as tissue scaffolds, in drug delivery, as antimicrobrials, and for biomineralization applications.^[2–6] However, the increasing realization that simple peptides with high cross-β fold propensity can achieve long-range ordered arrays comparable to lipid amphiphiles has now allowed for the creation of an entirely new architectural framework. This framework not only offers precisely controlled positioning of charges and hydrophobic patches along a robust nanotube surface, but also the systematic adjustment of that spacing in a …

Nest Predation, Food, And Female Age Explain Seasonal Declines In Clutch Size, Karie L. Decker, Courtney J. Conway, Joseph J. Fontaine

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The selection pressures responsible for intra- and interspecific variation in avian clutch size have been debated for over half a century. Seasonal declines in clutch size represent one of the most robust patterns in avian systems, yet despite extensive research on the subject, the mechanisms underlying this pattern remain largely unknown. We tested a combination of experimental and observational predictions to evaluate ten hypotheses, representing both evolutionary and proximate mechanisms proposed to explain seasonal declines in avian clutch size. In line with long held life-history theory, we found strong support for both an evolved and proximate response to food availability …

Habitat Selection By Adult Walleye During Spawning Season In Irrigation Reservoirs: A Patch Occupancy Modeling Approach, Dustin R. Martin, Larkin A. Powell, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Recruitment of walleye (Sander vitreus Mitchill) is limited in irrigation reservoirs of the Republican River basin in southwestern Nebraska. The causal mechanism for this limited recruitment is unknown, but may be related to a lack of suitable spawning habitat. Patch occupancy models were developed to describe variation in detection probability and habitat selection during spawning season using shoreline electrofishing data. Detection of adult walleye was negatively affected by water temperature, silt substrate, and woody cover. Adult walleye selected sites with cooler water temperatures and greater fetch at Enders Reservoir, and large rock substrate and no cover at Hugh Butler …
