Force–Frequency Effect Of Thickness Mode Langasite Resonators, Haifeng Zhang, Joseph A. Turner, Jiashi Yang, John A. Kosinski

Department of Mechanical and Materials Engineering: Faculty Publications

Langasite resonators are of recent interest for a variety of applications because of their good temperature behavior, good piezoelectric coupling, low acoustic loss and high Q factor. The force–frequency effect describes the shift in resonant frequency a resonator experiences due to the application of a mechanical load. A clear understanding of this effect is essential for many design applications such as pressure sensors. In this article, the frequency shift is analyzed theoretically and numerically for thin, circular langasite plates subjected to a pair of diametrical forces. In addition, the sensitivity of the force–frequency effect is analyzed with respect to the …

Observations Of Reproduction In Mountain Lions From Nebraska, Sam Wilson, Justin D. Hoffman, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Occurrences of mountain lions (Puma concolor) in Nebraska have been steadily increasing; however, reproductive activity in mountain lions has not been documented in the state. We present the first evidence of mountain lion reproduction in Nebraska since mountain lions recolonized the state in the early 1990s. On 28 February 2007, a spotted kitten was hit by a vehicle in northwestern Nebraska; and based on body length and weight, we estimate its age at 3.9 months. On 20 December 2008, a female mountain lion and spotted kitten were photographed in the northwestern part of the state. On 9 May …

New Records Of Bats From The British Virgin Islands, Gary G. Kwiecinski, Jean-Pierre Bacle, Kevel C. Lindsay, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

As currently understood the bat fauna of the British Virgin Islands consists of five species – Noctilio leporinus, Brachyphylla cavernarum, Artibeus jamaicensis, Tadarida brasiliensis , and Molossus molossus. Our knowledge of distribution of bats in the British Virgin Islands is far more limited than that in the United States Virgin Islands. As part of ongoing research on the bats of the Virgin Islands, recent brief surveying periods in the British Virgin Islands have produced new records for some islands. Also, our researching of existing museum collections has discovered unreported new records. Our new data adds information for five species …

The Joint Law Venture: A Pilot Study, Jayanth K. Krishnan

Articles by Maurer Faculty

This pilot study evaluates the effectiveness of law firms entering into joint ventures, an increasingly eyed business model particularly by American and British lawyers seeking to expand into promising financial markets. One country at the center of the joint venture experiment has been Singapore. With the strong encouragement of the Singaporean government (which has long embraced foreign investment), various elite law firms from the United States and Britain have been partnering with domestic Singaporean law firms for over the past decade. Because these foreign firms were traditionally barred from practicing Singaporean law on their own, the ‘joint law venture,’ or …

Charity And Information: Correcting The Failure Of A Disjunctive Social Norm, Brian Broughman, Robert Cooter

Articles by Maurer Faculty

Charitable donations fund social goods that the state and markets undersupply. Despite widespread belief in the importance of private charity, most Americans donate little or nothing. Experiments in behavioral economics show that anonymity, not human nature, causes low contributions. Anonymity poses a particular challenge for charity because of the special character of the obligation. Charity is a disjunctive social norm, meaning the obligation is owed to ‘A or B or C or …’. Disclosure of each individual’s aggregate conduct is necessary for the effectiveness of any disjunctive social norm. To revitalize charity we propose a public registry where each taxpayer …

Synthesis Of Satellite (Modis), Aircraft (Icartt), And Surface (Improve, Epa‐Aqs, Aeronet) Aerosol Observations Over Eastern North America To Improve Modis Aerosol Retrievals And Constrain Surface Aerosol Concentrations And Sources, Easan Drury, Daniel J. Jacob, Robert J. D. Spurr, Jun Wang, Yohei Shinozuka, Bruce E. Anderson, Antony D. Clarke, Jack Dibb, Cameron Mcnaughton, Rodney Weber

Department of Earth and Atmospheric Sciences: Faculty Publications

We use an ensemble of satellite (MODIS), aircraft, and ground‐based aerosol observations during the ICARTT field campaign over eastern North America in summer 2004 to (1) examine the consistency between different aerosol measurements, (2) evaluate a new retrieval of aerosol optical depths (AODs) and inferred surface aerosol concentrations (PM_2.5) from the MODIS satellite instrument, and (3) apply this collective information to improve our understanding of aerosol sources. The GEOS‐Chem global chemical transport model (CTM) provides a transfer platform between the different data sets, allowing us to evaluate the consistency between different aerosol parameters observed at different times and …

Vaishno Devi, The Most Famous Goddess Shrine In The Siwāliks, Georgana Foster, Robert Stoddard

Geography Program: Faculty Publications

Vaishno Devi in Jammu has been designated as the "Elder Sister" among the six other Devi shrines in a fairly narrow belt of the Siwāliks between the Yumunii and Chenāb Rivers. During the last few decades Vaishno Devi has become especially important. Pilgrimage to the shrine has increased from 30,000 to almost 7 million since Independence, when the political geography of the region increased accessibility, both physically and perceptually. The growth in the number of visitors can be attributed also to a change in administration of the shrine and to the tremendous increase in religious tourism. Vaishno Devi is now …

The Impact Of Blatant Stereotype Activation And Group Sex-Composition On Female Leaders, Crystal L. Hoyt, Stefanie K. Johnson, Susan Elaine Murphy, Kerry Hogue Skinnell

Jepson School of Leadership Studies articles, book chapters and other publications

The individual and combined impact of blatant stereotype activation and solo status or mixed-sex groups on the self-appraisals, performance, and anxiety of female leaders was examined across three laboratory studies. The first study utilized a two-condition, two-stage design in which female leaders were exposed to a blatant stereotype threat or control condition after which they completed a leadership task. In the second stage, the threatened leaders received a solo status manipulation (leading a group of men) while the control condition did not. In the second study a 2 (blatant threat, no blatant threat) by 2 (solo status, all-female group) fully …

Leadership And The More-Important-Than-Average Effect: Overestimation Of Group Goals And The Justification Of Unethical Behavior, Crystal L. Hoyt, Terry L. Price, Alyson E. Emrick

Jepson School of Leadership Studies articles, book chapters and other publications

This research investigates the empirical assumptions behind the claim that leaders exaggerate the importance of their group’s goals more so than non-leaders and that they may use these beliefs to justify deviating from generally accepted moral requirements when doing so is necessary for goal achievement. We tested these biased thought processes across three studies. The results from these three studies established the more-important-than-average effect, both for real and illusory groups. Participants claimed that their group goals are more important than the goals of others, and this effect was stronger for leaders than for non-leading group members. In Study 3, …

Dis-Manteling More, Peter Iver Kaufman

Jepson School of Leadership Studies articles, book chapters and other publications

Hilary Mantel's Wolf Hall, winner of the prestigious 2009 Booker-Man award for fiction, re-presents the 1520s and early 1530s from Thomas Cromwell's perspective. Mantel mistakenly underscores Cromwell's confessional neutrality and imagines his kindness as well as Thomas More's alleged cruelty. The book recycles old and threadbare accusations that More himself answered. "Dis-Manteling" collects evidence for the accuracy of More's answers and supplies alternative explanations for events and for More's attitudes that Mantel packs into her accusations. Wolf Hall is admirably readable, although prejudicial. Perhaps it is fair for fiction to distort so ascertainably, yet I should think that historians will …

Group Processes And Group Psychotherapy: Social Psychological Foundations Of Change In Therapeutic Groups, Donelson R. Forsyth

Jepson School of Leadership Studies articles, book chapters and other publications

Social psychology and clinical psychology share an interest in change. Rather than assuming that people are static and that psychological systems are immutable, social psychologists track the shifts in social attitudes, actions, values, and beliefs that result from individuals' everyday interactions in their social worlds. Similarly, clinical psychologists examine changes in adjustment, well-being, and dysfunction that are evidenced as people develop psychologically and physically, confront new life circumstances, or react effectively or less adaptively to daily life events.

A Man Of Passion And Vision: George Whitewolf, David E. Wilkins

Jepson School of Leadership Studies articles, book chapters and other publications

George Whitewolf's home was also just a stone's throw from Washington, D.C, and many Natives from the Lakota, Haudenosaunee, Blackfeet, Cheyenne, and countless other nations would stop at George's place for rest and ceremonies as they prepped for their difficult diplomatic visits to Congress and the BIA to discuss treaty rights, protest events like the Longest Walk, and other politically incendiary topics. In the 1970s, George was also very active in the American Indian Movement and his home was under frequent surveillance by the FBI.

Within a few years, George and his allies had made tremendous progress on both fronts …

An Argument For Guest Worker Programs, Javier S. Hidalgo

Jepson School of Leadership Studies articles, book chapters and other publications

Several noted economists and prominent international organizations have recently advocated for the implementation of guest worker programs in developed states.1 Their primary argument is that guest worker programs would serve as a powerful mechanism for reducing global poverty and inequality. For example, economist Dani Rodrik estimates that guest worker programs in wealthy states would generate $200 billion or more annually for poor countries. According to Rodrik, liberalizing the temporary movement of workers would “produce the largest possible gains for the world economy, and for poor countries in particular” in comparison with other policies, such as trade liberalization.

Linear Programming Models For Multi-Channel P2p Streaming Systems, Miao Wang, Lisong Xu, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

Most of the commercial P2P video streaming deployments support hundreds of channels and are referred to as multichannel systems. Measurement studies show that bandwidth resources of different channels are highly unbalanced and thus recent research studies have proposed various protocols to improve the streaming qualities for all channels by enabling cross-channel cooperation among multiple channels. However, there is no general framework for comparing existing and potential designs for multi-channel P2P systems. The goal of this paper is to establish tractable models for answering the fundamental question in multi-channel system designs: Under what circumstances, should a particular design be used to …

Development Of A Testbed For Wireless Underground Sensor Networks, Agnelo R. Silva, Mehmet C. Vuran

School of Computing: Faculty Publications

Wireless Underground Sensor Networks (WUSNs) constitute one of the promising application areas of the recently developed wireless sensor networking techniques. WUSN is a specialized kind of Wireless Sensor Network (WSN) that mainly focuses on the use of sensors that communicate through soil. Recent models for the wireless underground communication channel are proposed but few field experiments were realized to verify the accuracy of the models. The realization of field WUSN experiments proved to be extremely complex and time-consuming in comparison with the traditional wireless environment. To the best of our knowledge, this is the first work that proposes guidelines for …

Spatio-Temporal Soil Moisture Measurement With Wireless Underground Sensor Networks, Xin Dong, Mehmet C. Vuran

School of Computing: Conference and Workshop Papers

The main focus of this paper is to analyze the impact of the environment and network parameters on the estimation distortion of the soil moisture.More specifically, the effects of rainfall, soil porosity, and vegetation root zone are investigated by exploiting a rainfall model, in addition to the effects of sampling rate, network topology, and measurement signal noise ratio. Spatio-temporal correlation is characterized to develop a measurement distortion model with respect to these factors. The evaluations reveal that with porous soil and …

Face Needs, Intragroup Status, And Women’S Reactions To Socially Aggressive Face Threats, Erin K. Willer, Jordan Soliz

Department of Communication Studies: Faculty Publications

Given the potential negative consequences of being a recipient of such behavior, the role of positive face needs, intragroup status, and the face-threatening nature of social aggression in predicting cor-relates of negative affect experienced as a result of being a target of SAFTs, including the face threat of the response, forgiveness, and well-being was investigated. On the basis of the survey responses from 199 college-aged women, findings indicated that targets’ positive face needs and intragroup status are directly and indirectly associated with forgiveness and overall well-being. Implications for these findings in relation to theorizing about face and intragroup identity as …

A Partial Taxonomy Of Substitutability And Interchangeability, Shant Karakashian, Robert J. Woodward, Berthe Y. Choueiry, Steven D. Prestwich, Eugene C. Freuder

School of Computing: Conference and Workshop Papers

Substitutability, interchangeability and related concepts in Constraint Programming were introduced approximately twenty years ago and have given rise to considerable subsequent research. We survey this work, classify, and relate the different concepts, and indicate directions for future work, in particular with respect to making connections with research into symmetry breaking. This paper is a condensed version of a larger work in progress.

Survivor Buddy And Scigirls: Affect, Outreach, And Questions, Robin R. Murphy, Vasant Srinivasan, Negar Rashidi, Brittany Duncan, Aaron Rice, Zachary Henkel, Marco Garza, Cliff Nass, Victoria Groom, Takis Zourntos, Roozbeh Daneshwar, Sharath Prasad

School of Computing: Conference and Workshop Papers

This paper describes the Survivor Buddy human-robot interaction project and how it was used by four middle-school girls to illustrate the scientific process for an episode of “SciGirls”, a Public Broadcast System science reality show. Survivor Buddy is a four degree of freedom robot head, with the face being a MIMO 740 multi-media touch screen monitor. It is being used to explore consistency and trust in the use of robots as social mediums, where robots serve as intermediaries between dependents (e.g., trapped survivors) and the outside world (doctors, rescuers, family members). While the SciGirl experimentation was neither statistically significant nor …

Quantitative Evaluation Of The Bim-Assisted Construction Detailed Cost Estimates, Zhigang Shen, Raja R. A. Issa

Department of Construction Engineering and Management: Faculty Publications

The increased interest in using Building Information Modeling (BIM) in detailed construction cost estimates calls for methodologies to evaluate the effectiveness of BIM-Assisted Detailed Estimating (BADE) tools in generating detailed construction cost estimates. The focus of this study is on developing a quantified evaluation method to measure the impact of these BADE tools. Further, in order to understand the cognitive details of the estimator, this study also tested and evaluated the impact of the visualization factor and the compound impact of the visualization factor and aggregated calculation factor on the construction cost-estimating process. Two types of BADE tools were tested …

Refugees As People: The Portrayal Of Refugees In American Human Interest Stories, Sarah Steimel

Department of Communication Studies: Faculty Publications

This study combines discourse analysis and narrative analysis (Yin 2007) to examine top US newspapers’ coverage of refugees in American human interest stories. I find that the refugees are presented (a) as prior victims; (b) as in search of the American Dream; and (c) as unable to achieve the American Dream. As human-interest features, the stories provide a largely positive portrayal of individual refugees and their families. However, the human interest stories also depict refugees as current victims of the American economic crisis; deeply frustrated by their inability to achieve the American Dream. Together these discourses represent a narrative of …

A Novel Weighted-Graph-Based Grouping Algorithm For Metadata Prefetching, Peng Gu, Jun Wang, Yifeng Zhu, Hong Jiang, Pengju Shang

School of Computing: Faculty Publications

Although data prefetching algorithms have been extensively studied for years, there is no counterpart research done for metadata access performance. Existing data prefetching algorithms, either lack of emphasis on group prefetching, or bearing a high level of computational complexity, do not work well with metadata prefetching cases. Therefore, an efficient, accurate, and distributed metadata-oriented prefetching scheme is critical to leverage the overall performance in large distributed storage systems. In this paper, we present a novel weighted-graph-based prefetching technique, built on both direct and indirect successor relationship, to reap performance benefit from prefetching specifically for clustered metadata servers, an arrangement envisioned …

Xlp: A Cross-Layer Protocol For Efficient Communication In Wireless Sensor Networks, Mehmet C. Vuran, Ian F. Akyildiz

School of Computing: Faculty Publications

Severe energy constraints of battery-powered sensor nodes necessitate energy-efficient communication in Wireless Sensor Networks (WSNs). However, the vast majority of the existing solutions is based on classical layered protocols approach, which leads to significant overhead. It is much more efficient to have a unified scheme which blends common protocol layer functionalities into a cross-layer module. In this paper, a cross layer protocol (XLP) is introduced, which achieves congestion control, routing, and medium access control in a cross-layer fashion. The design principle of XLP is based on the cross-layer concept of initiative determination, which enables receiver-based contention, initiative-based forwarding, local …

Polishing Esthetic Restorative Materiai, Caren M. Barnes

College of Dentistry: Faculty Publications

When esthetic dental restorations are encountered during charting, they should be included in the treatment plan for the specific polishing procedures that are required. If the brand and type of esthetic restoration are known through the patient chart, the polishing procedures and products used should be those recommended by the manufacturer. If not possible, alternative polishing procedures should be used. A cleaning agent containing feldspar and rubber polishing cup can be used on all esthetic restorative materials with no chance of damage to the surface characterization.

The principles for polishing esthetic restorations are the same as for natural teeth. If …

Isomer Identification And Resolution In Small Gold Clusters, Wei Huang, Rhitankar Pal, Lei-Ming Wang, Xiao Cheng Zeng, Lai-Sheng Wang

Xiao Cheng Zeng Publications

A variety of experimental techniques are used to resolve energetically close isomers of Au_{7 ⁻} and Au_{8 ⁻} by combining photoelectron spectroscopy and ab initio calculations. Two structurally distinct isomers are confirmed to exist in the cluster beam for both clusters. Populations of the different isomers in the cluster beam are tuned using Ar-tagging, O₂-titration, and isoelectronic atom substitution by Cu and Ag. A new isomer structure is found for Au_{7 ⁻}, which consists of a triangular Au₆ unit with a dangling Au atom. Isomer-specific photoelectron spectra of Au_{8 ⁻} are obtained …

Childhood Depression, Kelly Brey Love, Susan M. Swearer Napolitano

Department of Educational Psychology: Faculty Publications

It has only been within the past two decades that the majority ofclinicians and researchers reached agreement that children can experience a depressive disorder. Initially, researchers believed children’s lack of psychosexual development prohibited development of depression in childhood.

There has also been disagreement regarding which symptomatology comprises childhood depression, and how it differs from depression in adults. Many clinicians and researchers shared the belief that depression in children was “masked” by other symptoms (e.g., aggression, enuresis, anxiety, among others). More recent research has identified and emphasized the similarities between depressive symptoms experienced by adults and children. Cohort data suggest that …
