Archiving & Records Management Perspectives On Electronic-Only Publications For Nomenclature, Sue Ann Gardner

University of Nebraska-Lincoln Libraries: Faculty Publications

I fully support the establishment of taxonomic names in electronic-only publications and would like to make some recommendations based on my professional experience in archival sciences, as a Scholarly Communications Librarian. The proposed amendment to the Code needs only to be explicit in what is required of authors and publishers for electronic-only publication, and all contingencies can be covered. In this generation we have one foot in the world of paper and the other now firmly planted in the electronic realm. This special position will be relatively short-lived, and we would be doing a great service to our successors if …

Compact Trench-Based Silicon-On-Insulator Rib Waveguide Ring Resonator With Large Free Spectral Range, Seunghyun Kim, Gregory P. Nordin, Weisheng Hu, Yusheng Qian, Jiguo Song, Gregory L. Wojcik

Faculty Publications

We demonstrate a compact trench-based silicon-on-insulator (SOI) rib waveguide ring resonator comprised of trench-based bends and splitters. It has a perimeter of 50 μm and occupies an area of only 25×25 μm. The measured free spectral range (FSR) is 13.2 nm, which the largest reported for an SOI rib waveguide ring resonator. The measured FSR, full width at half maximum, and quality factor match reasonably well with analytical calculations. Further calculation shows that a FSR of 50.8 nm is achievable for an SOI rib waveguide ring resonator with a perimeter of 15 μm.

Has The Marital Time Cost Of Parenting Changed Over Time?, Jeffrey P. Dew

Faculty Publications

Qualitative and quantitative research has suggested that married couples handle the increasing demands of intensive parenting norms and work expectations by reducing spousal time (e.g., the time that spouses spend alone with each other). Using nationally representative time-diary data, this study examined whether married individuals with children at home lost more spousal time in the years 1975–2003 than individuals without children at home. The analyses showed that on average married individuals have reduced their spousal time by 50 minutes a day. Contrary to expectations, however, individuals with minor children at home had lower time declines than individuals without children. The …

Well-Being On Planet Earth, Ed Diener, William Tov

Research Collection School of Social Sciences

The Gallup World Poll allows a look at how humanity is flourishing, based on the answers of survey respondents sampled from across the globe. Several conclusions are clear. First, how people are doing depends enormously on the society in which they live, and nations vary from doing very well to extremely poorly. In terms of subjective well-being, nations vary greatly, in both judgments of overall life and in positive and negative emotions. The best predictors of global life judgments were income and ownership of modern conveniences, whereas the best predictors of emotions were social factors such as the control of …

Thin Film Integrated Capacitors With Sputtered-Anodized Niobium Pentoxide Dielectric For Decoupling Applications, Susan Jacob

Graduate Theses and Dissertations

Electronics system miniaturization is a major driver for high-k materials. High-k materials in capacitors allow for high capacitance, enabling system miniaturization. Ta2O5 (k~24) has been the dominant high-k material in the electronic industry for decoupling capacitors, filter capacitors, etc. In order to facilitate further system miniaturization, this project has investigated thin film integrated capacitors with Nb2O5 dielectric. Nb2O5 has k~41 and is a potential candidate for replacing Ta2O5. But, the presence of suboxides (NbO2 and NbO) in the dielectric deteriorates the electrical properties (leakage current, thermal instability of capacitance, etc.). Also, the high oxygen solubility of niobium results in oxygen …

Applications Of Variable Number Tandem Repeat Genotyping In The Validation Of An Animal Medical Model And Gene Flow Studies In Threatened Populations Of Reptiles, Candace D. Smith

Graduate Theses and Dissertations

We used variable number tandem repeats (VNTR) to validate the chicken as a human medical model for Pulmonary Arterial Hypertension. We identified seven regions on four chromosomes and interrogated for VNTR markers that significantly associate with Pulmonary Hypertension Syndrome/ascites. In those regions, we identified 7 candidate genes; AGTR1, ACE, p38MAPK, SST, 5HT2B, NET1, and CALM3 for further analysis as significantly contributing QTL for ascites/PHS. We also used variable number tandem repeats to measure gene flow and gather evidence for multiple paternity in a population of Timber rattlesnakes, Crotalus horridus. We were able to verify 1 VNTR that can be used …

Evaluation Of Best Management Practices To Reduce Nutrients Runoff In Watersheds In Arkansas, Hector German Rodriguez Diaz

Graduate Theses and Dissertations

There are many non point sources (NPS) of pollution issues across the state of Arkansas. Each region of the state has different concerns. Many watersheds have been included in the Arkansas's 2008 303(d) list for NPS impairments with sediment and nutrients being the primary causes of concern. This research hypothesized that there are no cost or net returns risks when adopting best management practices (BMPs) to control nutrients runoff and that selection, timing, placement and cost have no impact on the implementation of BMPs. Using two priority watersheds, the L'Anguille River and the Lincoln Lake, as examples, the environmental benefits …

Angular Rigidity In 3d: Combinatorial Characterizations And Algorithms, Audrey Lee-St.John, Ileana Streinu

Computer Science: Faculty Publications

Constraint-based CAD software, used by engineers to design sophisticated mechanical systems, relies on a wide range of geometrical constraints. In this paper we focus on one special case: angular constraints in 3D. We give a complete combinatorial characterization for generic minimal rigidity in two new models: line- plane-and-angle and body-and-angle structures. As an immediate consequence, we obtain efficient algorithms for analyzing angular rigidity.

The Relationship Between Web Accessibility Policy And Practice In Postsecondary Institutions, Michael Whitney

Dissertations

From computer workstations to the world of the web, statutes and policies have afforded students with disabilities the right to participate in postsecondary education in a non-discriminatory manner. Automatic doors and adjustable tables are a commonplace on campuses and represent prime examples of accessible policy adherence, but what affect do accessible website design policies have on practice? The answer is monumental for the students with disabilities that rely on the integration of electronic curb cuts into institutional websites. In 2006, Illinois Board of Higher Education required public postsecondary institutions to develop and implement a website policy, report on the accessibility …

An Exploratory Study Of The Relationship Among Perceived Personal And Social Competence, Health Risk Behaviors, And Academic Achievement Of Selected Undergraduate Students, Darson Lee Rhodes

Dissertations

A sample of 656 undergraduate students from multiple sections of an introductory nutrition course, a personal health course, and a physical fitness course at a large Midwestern University completed one of four surveys. Using matrix sampling, each participant completed a survey measuring one of four personal and social competence constructs; coping skills, interpersonal skills, intrapersonal skills, or judgment skills; 11 health risk behaviors, and college grade point average (GPA). Descriptive statistics, correlations, and multiple regression analyses were calculated to determine relationships among these variables. Thirteen statistically significant correlations were found among personal and social competence constructs and health risk behaviors. …

A Case Study Of How A Large Multilevel Efl Writing Class Experiences And Perceives Multiple Interaction Activities, Hsien-Chuan Lin

Dissertations

The purpose of this study was to examine students' experiences and perceptions of multiple interaction activities (self-directed, peer, and teacher feedback) implemented in a large multilevel EFL writing class in one private technological university in the southern part of Taiwan. Large size writing classes, quite common in private institutions of higher education in Taiwan, cannot be effectively operated to meet individual students' needs in improving their writing performance. Low achievers have difficulties in keeping up with competent writers in learning writing skills while advanced students complain of their learning too little from the class. This research, based on the activity …

A Critical Analysis Of Rural Teachers' Usage Of Online Communities, Sherri A. Snider

Dissertations

The purpose of this study was to analyze data related to rural teachers' use of online communities. Rural teachers are often isolated in their practice and sometimes have difficulty connecting with other teachers with their same assignments or needs due to their professional setting. As Internet availability increases and online communities proliferate, teachers have more opportunity than ever to seek personal and professional support in virtual relationships when face-to-face ones are not easily available. In small schools such as the ones included in this study, teachers can become burned out as they perform the difficult task of teaching with few …

Climate Change In The Changing Climate Of News Media: A Comparative Analysis Of Mainstream Media And Blog Coverage Of Climate Change In The United States And The People's Republic Of China, 2005-2008, Lei Xie

Dissertations

The social construction of climate change has been an enduring interest to media scholars. Extensive research has been done to explore how the mass media portrayed climate change and how the influence of their representations contributed to the social reality of climate change. However, most research focused on the news media in the United States and other developed countries and ignored China--the second largest greenhouse gases emitter in the world. This oversight has led to a sociological map of global climate change with the one of the biggest puzzle pieces missing. In addition, traditional news media were in the spotlight …

The Role Of Spatial And Genetic Modeling To Biogeography, Dolly Lyne Crawford

Biology ETDs

One of the most persistent challenges in biology is explaining the distribution of animal taxa. Quantitative explanations for the distribution of organisms are challenged by the complexity of factors that potentially limit a species range, including topography, ecology, climate and biology. Because of limits on data and approaches, early biogeographers were hampered in their ability to explain patterns. Here, I benefit from two primary developments in biogeography. My research draws from the accumulation of data across several scientific disciplines and advances in spatial and statistical approaches to examine the distribution of animal taxa within an integrative biogeography framework. I combine …

Facing Defacement: Factors Influencing Indigenous Patients In Provider-Patient Communication In Baja Verapaz, Guatemala, Laura L. Burton

Communication ETDs

The purpose of this ethnographic research was to explain the factors influencing Achi patients in provider-patient interactions in Baja Verapaz, Guatemala. I explored the complex intercultural challenges influencing the interactions between biomedically-trained providers and indigenous patients. Data collection involved participant observation and twenty-four informal field interviews in Guatemala. I utilized thematic analysis to identify and understand the factors influencing Achi patients when interacting with health care providers. Findings reveal that the Achi patients are influenced in provider-patient interactions by the reciprocal interaction among four major factors: environment, beliefs, emotional effect, and experiences. In addition, subthemes were identified for each of …

Immune Regulation Of The Host Autophagic Response And The Elimination Of Mycobacterium Tuberculosis, Sergio A. De Haro

Biomedical Sciences ETDs

Autophagy is an immune effector response against a variety of intracellular pathogens, including Mycobacterium tuberculosis. Mycobacteria survive in macrophages by blocking maturation of the phagosome. Induction of autophagy by the T helper 1 (Th1) cytokine IFN-γ, or amino acid starvation, enables macrophages to overcome the phagosome maturation block and impedes mycobacterial survival. This study investigates the role of T helper 2 (Th2) cytokines Interleukin 4 (IL-4) and Interleukin 13 (IL-13) in autophagy in macrophages and their ability to eliminate intracellular mycobacteria. The Th2 cytokines abrogated autophagy and autophagy-induced transfer of mycobacteria into lysosomal compartments, thus enhancing mycobacterial survival within infected …

Microsphere Based Protease Assays And High Throughput Screening Of Bacterial Toxin Proteases, Matthew J. Saunders

Biomedical Sciences ETDs

Proteases, proteins which cleave peptide bonds in other proteins, are a large and varied group of proteins which regulate a variety of physiological processes. Methodologies to study proteases are often protease specific and often differ greatly from the roles proteases play in vivo. In vitro protease assays often use peptide based substrates, which do not take into account highly specific interactions distal from the proteolytic site of peptide cleavage on protease substrates. In the work described here we have developed a microsphere based protease assay, capable of using full length protease substrates, and have successfully measured proteolytic activity via loss …

Adult Neural Stem/Progenitor Cells In Response To Their Microenvironment: Proliferation, Differentiation, And Migration, Basam Z. Barkho

Biomedical Sciences ETDs

The plasticity of adult neural stem/progenitor cells allows a differential response to a variety of environmental cues. Over the past decade, significant research efforts have been devoted into understanding the regulation of neural stem/progenitor cells due to their promising potential for cell replacement therapies in adult neurological diseases. It has been demonstrated that after brain injury both endogenous and grafted neural stem/progenitor cells have the ability to proliferate to expand their number, migrate long distances to the lesioned site and differentiate into new specific neurons to replace the ones that have been lost. All these procedure are regulated by extrinsic …

To Trust Or Not To Trust? Predicting Online Trusts Using Trust Antecedent Framework, Viet-An Nguyen, Ee Peng Lim, Jing Jiang, Aixin Sun

Research Collection School Of Computing and Information Systems

This paper analyzes the trustor and trustee factors that lead to inter-personal trust using a well studied Trust Antecedent framework in management science. To apply these factors to trust ranking problem in online rating systems, we derive features that correspond to each factor and develop different trust ranking models. The advantage of this approach is that features relevant to trust can be systematically derived so as to achieve good prediction accuracy. Through a series of experiments on real data from Epinions, we show that even a simple model using the derived features yields good accuracy and outperforms MoleTrust, a trust …

On The Untraceability Of Anonymous Rfid Authentication Protocol With Constant Key-Lookup, Bing Liang, Yingjiu Li, Tieyan Li, Robert H. Deng

Research Collection School Of Computing and Information Systems

In ASIACCS'08, Burmester, Medeiros and Motta proposed an anonymous RFID authentication protocol (BMM protocol [2]) that preserves the security and privacy properties, and achieves better scalability compared with other contemporary approaches. We analyze BMM protocol and find that some of security properties (especial untraceability) are not fulfilled as originally claimed. We consider a subtle attack, in which an adversary can manipulate the messages transmitted between a tag and a reader for several continuous protocol runs, and can successfully trace the tag after these interactions. Our attack works under a weak adversary model, in which an adversary can eavesdrop, intercept and …

Insights Into Malware Detection And Prevention On Mobile Phones, Qiang Yan, Yingjiu Li, Tieyan Li, Robert H. Deng

Research Collection School Of Computing and Information Systems

The malware threat for mobile phones is expected to increase with the functionality enhancement of mobile phones. This threat is exacerbated with the surge in population of smart phones instilled with stable Internet access which provides attractive targets for malware developers. Prior research on malware protection has focused on avoiding the negative impact of the functionality limitations of mobile phones to keep the performance cost within the limitations of mobile phones. Being different, this paper investigates the positive impact of these limitations on suppressing the development of mobile malware. We study the state-of-the-art mobile malware, as well as the progress …

Computationally Secure Hierarchical Self-Healing Key Distribution For Heterogeneous Wireless Sensor Networks, Yanjiang Yang, Jianying Zhou, Robert H. Deng, Feng Bao

Research Collection School Of Computing and Information Systems

Self-healing group key distribution is a primitive aimed to achieve robust key distribution in wireless sensor networks (WSNs) over lossy communication channels. However, all the existing self-healing group key distribution schemes in the literature are designed for homogenous WSNs that do not scale. In contract, heterogeneous WSNs have better scalability and performance. We are thus motivated to study self-healing group key distribution for heterogeneous WSNs. In particular, we propose the concept of hierarchical self-healing group key distribution, tailored to the heterogeneous WSN architecture; we further revisit and adapt Dutta et al.’s model to the setting of hierarchical self-healing group …
