Development And Reform Of The Iraqi Police Forces, C. Anthony Pfaff Dr.

Books, Monographs & Collaborative Studies

Despite 4 years of millions of dollars in aid, equipment, education, and advisors, Iraqi police force development lags far behind the military. Numerous reasons are offered to account for this gap: corrupt practices left over from the previous regime, infiltration by militias, weak leadership, competition by better armed and organized criminal and militant groups, and so on. However, the military is also subject to these same influences, thus none of these explanations by themselves or in combination are satisfactory. The author argues that the poor political and security environment impacts social, political, and cultural factors in ways that are predictable, …

Transforming To Effects-Based Operations: Lessons From The United Kingdom Experience, Andrew M. Dorman Dr.

Books, Monographs & Collaborative Studies

The author examines the extent to which the United Kingdom (UK) has transitioned to effects-based operations to ascertain: (1) Areas where the U.S. Army could draw lessons from UK policies; (2) Areas where the U.S. Army and the British Ministry of Defence could develop integrated or complementary approaches and doctrines towards transformation for future alliance/coalition operations; and (3) Implications for the U.S. Army for working with the UK. This monograph is subdivided into four parts. Section 1 is a review of the evolution of British defence policy since the end of the Cold War and evaluates the degree to which …

Jordanian National Security And The Future Of Middle East Stability, W. Andrew Terrill Dr.

Books, Monographs & Collaborative Studies

The United States and Jordan have maintained a valuable mutually-supportive relationship for decades as a result of shared interests in a moderate, prosperous, and stable Middle East. In this monograph, the author highlights Jordan’s ongoing value as a U.S. ally and considers ways that the U.S.-Jordanian alliance might be used to contain and minimize problems of concern to both countries. Although Jordan is not a large country, it is an important geographical crossroads within the Middle East and has been deeply involved in many of the most important events in the region’s modern history. In recent years, the importance of …

A Comparison Of Oral Motor And Production Training For Children With Speech Sound Disorders, Karen Forrest, Jenya Iuzzini-Seigel

Speech Pathology and Audiology Faculty Research and Publications

Despite the many debates about the usefulness of nonspeech oral motor exercises (NSOMEs) in the treatment of speech disorders, few controlled experiments have evaluated their efficacy in the remediation of phonological/articulatory disorders (PADs). More importantly, the relative effect of NSOMEs compared with traditional production treatment (PT) has not been established. The current study employed an alternating treatment design to evaluate changes in production of sounds targeted by NSOMEs and PT in nine children with PAD. Each subject received treatment on two linguistically distinct sounds in which one sound was treated with NSOMEs and the second sound was targeted with PT. …

United States Opposition To The 1998 Rome Statute Establishing An International Criminal Court: Is The Court's Jurisdiction Truly Complementary To National Criminal Jurisdictions?, Jimmy Gurulé

Journal Articles

Although the United States supports the creation of a permanent International Criminal Court (ICC), it opposes such a court as set forth in the 1998 Rome Statute because it leaves open the potential for United States military personnel and government officials to be prosecuted for unintended loss of civilian life. Can the United States formulate a legal argument to support its view that inadvertent civilian casualties should not be considered a war crime within the jurisdiction of the ICC? The article argues that it can because the ICC’s jurisdiction under the Rome Statute is not complementary to national prosecutions held …

Anomie And The Marketing Function: The Role Of Control Mechanisms, Amit Saini, Mike Krush, Jean L. Johnson

Department of Marketing: Faculty Publications

The theoretical notion of anomie is used to examine the impact of top management’s control mechanisms on the environment of the marketing function. Based on a literature review and in-depth field interviews with marketing managers in diverse industries, a conceptual model is proposed that incorporates the two managerial control mechanisms, viz. output and process control, and relates their distinctive influence to anomie in the marketing function. Three contingency variables, i.e., resource scarcity, power, and ethics codification, are proposed to moderate the relationship between control mechanisms and anomie. The authors also argue for the link between anomic environments and the propensity …

Matrix Model Superpotentials And Ade Singularities, Carina Curto

Department of Mathematics: Faculty Publications

We use F. Ferrari’s methods relating matrix models to Calabi–Yau spaces in order to explain much of Intriligator and Wecht’s ADE classification of N = 1 superconformal theories which arise as RG fixed points of N = 1 SQCD theories with adjoints. We find that ADE superpotentials in the Intriligator–Wecht classification exactly match matrix model superpotentials obtained from Calabi–Yau with corresponding ADE singularities. Moreover, in the additional Ô, Â, Dˆ and Ê cases we find new singular geometries. These “hat” geometries are closely related to their ADE counterparts, but feature non-isolated singularities. As a byproduct, we give simple descriptions for …

Effects Of The Synergist S,S,S-Tributyl Phosphorotrithioate On Indoxacarb Toxicity And Metabolism In The European Corn Borer, Ostrinia Nubilalis (Hübner), Analiza P. Alves, William J. Allgeier, Blair D. Siegfried

Department of Entomology: Faculty Publications

The toxicity of the oxadiazine insecticide indoxacarb to the European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), was evaluated in the presence and absence of S,S,S-tributyl phosphorotrithioate (DEF), an inhibitor of hydrolytic metabolism. Bioassays involving topical application of different concentrations of indoxacarb to third instars of a susceptible O. nubilalis laboratory strain were performed, and in vitro metabolism experiments involving [¹⁴C] indoxacarb were examined to determine the role of hydrolytic metabolism in indoxacarb activation. Indoxacarb toxicity decreased in the presence of DEF indicating antagonism of toxicity. Results of in vivo and in vitro inhibition experiments indicated a …

A Synopsis Of Nebraska Grasshopper Distributions, Mathew L. Brust, William Wyatt Hoback, Robert J. Wright

Department of Entomology: Faculty Publications

Between 2005 and 2007, 656 new county records and eight new state records were obtained for Nebraska’s short-horned grasshoppers (Acrididae and Romaleidae). This represents an increase of 30% in the known grasshopper county records in Nebraska. Based on the large number of new distribution records, it appears that the previous distributions of Nebraska’s grasshoppers greatly underestimated the actual distributions. The new grasshopper state records were: Boopedon gracile, Chloealtis abdominalis, Encoptolophus subgracilis, Melanoplus bispinosus, Melanoplus borealis, Melanoplus punctulatus, Paratylotropidia brunneri, and Psinidia fenestralis were obtained. These new records will aid in both grasshopper monitoring for pest outbreaks and in conservation of …

An Automatic Bridge Detection Technique For Multispectral Images, D. Chaudhuri, Ashok Samal

School of Computing: Conference and Workshop Papers

Extraction of features from images has been a goal of researchers since the early days of remote sensing. While significant progress has been made in several applications, much remains to be done in the area of accurate identification of high-level features such as buildings and roads. This paper presents an approach for detecting bridges over water bodies from multispectral imagery. The multispectral image is first classified into eight land-cover types using a majority-must-be-granted logic based on the multiseed supervised classification technique. The classified image is then categorized into a trilevel image: water, concrete, and background. Bridges are then recognized in …

A Security Framework For Wireless Sensor Networks Utilizing A Unique Session Key, Yong Wang, Byrav Ramamurthy, Yuyan Xue, Xukai Zou

School of Computing: Conference and Workshop Papers

Key management is a core mechanism to ensure the security of applications and network services in wireless sensor networks. It includes two aspects: key distribution and key revocation. Many key management protocols have been specifically designed for wireless sensor networks. However, most of the key management protocols focus on the establishment of the required keys or the removal of the compromised keys. The design of these key management protocols does not consider the support of higher level security applications. When the applications are integrated later in sensor networks, new mechanisms must be designed. In this paper, we propose a security …

Cross-Layer Packet Size Optimization For Wireless Terrestrial, Underwater, And Underground Sensor Networks, Mehmet C. Vuran, Ian F. Akyildiz

School of Computing: Conference and Workshop Papers

In this paper, a cross-layer solution for packet size optimization in wireless sensor networks (WSN) is introduced such that the effects of multi-hop routing, the broadcast nature of the physical wireless channel, and the effects of error control techniques are captured. A key result of this paper is that contrary to the conventional wireless networks, in wireless sensor networks, longer packets reduce the collision probability. Consequently, an optimization solution is formalized by using three different objective functions, i.e., packet throughput, energy consumption, and resource utilization. Furthermore, the effects of end-to-end latency and reliability constraints are investigated that may be required …

Seismic Facies And Stratigraphy Of The Cenozoic Succession In Mcmurdo Sound, Antarctica: Implications For Tectonic, Climatic And Glacial History, Christopher R. Fielding, Joanne Whittaker, Stuart A. Henrys, Terry J. Wilson, Timothy R. Naish

Department of Earth and Atmospheric Sciences: Faculty Publications

Integration of data from fully cored stratigraphic holes with an extensive grid of seismic reflection lines in McMurdo Sound, Antarctica, has allowed the formulation of a new model for the evolution of the Cenozoic Victoria Land Basin of the West Antarctic Rift. The Early Rift phase (Eocene to Early Oligocene) is recorded by wedges of strata confined by early extensional faults, and which contain seismic facies consistent with drainage via coarse-grained fans and deltas into discrete, actively subsiding grabens and half-grabens. The Main Rift phase (Early Oligocene to Early Miocene) is represented by a lens of strata that thickens symmetrically …

Full-Wave Finite-Difference Time-Domain Simulation Of Electromagnetic Cloaking Structures, Yan Zhao, Christos Argyropoulos, Yang Hao

Department of Electrical and Computer Engineering: Faculty Publications

This paper proposes a radial dependent dispersive finitedifference time-domain method for the modeling of electromagnetic cloaking structures. The permittivity and permeability of the cloak are mapped to the Drude dispersion model and taken into account in dispersive FDTD simulations. Numerical simulations demonstrate that under ideal conditions, objects placed inside the cloak are ‘invisible’ to external electromagnetic fields. However for the simplified cloak based on linear transformations, the back scattering has a similar level to the case of a PEC cylinder without any cloak, rendering the object still being ‘visible’. It is also demonstrated numerically that the simplified cloak based on …

Ex–Dividend Day Price And Volume: The Case Of 2003 Dividend Tax Cut, Yi Zhang, Kathleen A. Farrell, Todd A. Brown

Department of Finance: Faculty Publications

We examine the impact of the 2003 dividend tax cut, which removes the differential taxation between dividends and capital gains for individual investors, on the ex–dividend day price and trading volume. We find the ex–dividend day price and volume are affected by taxes, risk, and transaction costs. The ex–dividend day price drop ratio (excess return) increases (decreases) and dividend clienteles weaken after the tax cut. Ex–dividend day abnormal volume among high dividend yield stocks decreases after the tax cut consistent with a diminished motivation for tax–induced trading. Our results suggest that individual investors have a measurable effect on the ex–dividend …

The following sample editions illustrate the theory and method of the Oxford Hebrew Bible. The Deuteronomy sample, edited by Sidnie White Crawford, concerns a text with one ancient edition, while the Kings sample, edited by Jan Joosten, and the Jeremiah sample, edited by Eugene Ulrich, concern texts with two ancient editions. The arguments that justify the editorial decisions are presented in the apparatuses and text-critical commentaries. (The detailed introductory chapters are not included.) The critical texts, following the conventions discussed in the previous article, contain the following sigla: a superlinear circlet to indicate an entry in the apparatus where the …

Comparison Of Amylose Determination Methods And The Development Of A Dual Wavelength Iodine Binding Technique, Thianming Zhu, David S. Jackson, Randy L. Wehling, Bhima Geera

Department of Food Science and Technology: Faculty Publications

It has long been recognized that limitations exist in the analytical methodology for amylose determination. This study was conducted to evaluate various amylose determination methods. Purified amylose and amylopectin fractions were obtained from com, rice, wheat, and potato and then mixed in proportion to make 10, 20, 30, 50, and 80% amylose content starch samples for each source. These samples, considered amylose standards, were analyzed using differential scanning calorimetry (DSC), high-performance size-exclusion chromatography (HPSEC), and iodine binding procedures to generate standard curves for each of the methods. A single DSC standard equation for cereal starches was developed. The standard curve …

Cell Autonomous Expression Of Inflammatory Genes In Biologically Aged Fibroblasts Associated With Elevated Nf-Kappab Activity., Andres Kriete, Kelli L Mayo, Nirupama Yalamanchili, William Beggs, Patrick Bender, Csaba Kari, Ulrich Rodeck

Department of Dermatology and Cutaneous Biology Faculty Papers

BACKGROUND: Chronic inflammation is a well-known corollary of the aging process and is believed to significantly contribute to morbidity and mortality of many age-associated chronic diseases. However, the mechanisms that cause age-associated inflammatory changes are not well understood. Particularly, the contribution of cell stress responses to age-associated inflammation in 'non-inflammatory' cells remains poorly defined. The present cross-sectional study focused on differences in molecular signatures indicative of inflammatory states associated with biological aging of human fibroblasts from donors aged 22 to 92 years. RESULTS: Gene expression profiling revealed elevated steady-state transcript levels consistent with a chronic inflammatory state in fibroblast cell-strains …

Towards Universal Cover Decoding, Nathan Axvig, Deanna Dreher, Katherine Morrison, Eric T. Psota, Lance C. Pérez, Judy L. Walker

Department of Mathematics: Faculty Publications

Low complexity decoding of low-density paritycheck (LDPC) codes may be obtained from the application of iterative message-passing decoding algorithms to the bipartite Tanner graph of the code. Arguably, the two most important decoding algorithms for LDPC codes are the sum-product decoder and the min-sum (MS) decoder. On a bipartite graph without cycles (a tree), the sum-product decoder minimizes the probability of bit error, while the min-sum decoder minimizes the probability of word error [9]. While the behavior of sum-product and min-sum is easily understood when operating on trees, their behavior becomes much more difficult to characterize when the Tanner graph …

Ldpc Codes From Voltage Graphs, Christine A. Kelley, Judy L. Walker

Department of Mathematics: Faculty Publications

Several well-known structure-based constructions of LDPC codes, for example codes based on permutation and circulant matrices and in particular, quasi-cyclic LDPC codes, can be interpreted via algebraic voltage assignments. We explain this connection and show how this idea from topological graph theory can be used to give simple proofs of many known properties of these codes. In addition, the notion of abelianinevitable cycle is introduced and the subgraphs giving rise to these cycles are classified. We also indicate how, by using more sophisticated voltage assignments, new classes of good LDPC codes may be obtained.

Average Min-Sum Decoding Of Ldpc Codes, Nathan Axvig, Deanna Dreher, Katherine Morrison, Eric T. Psota, Lance C. Pérez, Judy L. Walker

Department of Mathematics: Faculty Publications

Simulations have shown that the outputs of minsum (MS) decoding generally behave in one of two ways: the output either eventually stabilizes at a codeword or eventually cycles through a finite set of vectors that may include both codewords and non-codewords. This inconsistency in MS across iterations has significantly contributed to the difficulty in studying the performance of this decoder. To overcome this problem, a new decoder, average min-sum (AMS), is proposed; this decoder outputs the average of the min-sum output vectors over a finite set of iterations. Simulations comparing MS, AMS, linear programming (LP) decoding, and maximum likelihood (ML) …

Highly Resolved Absolute Cross-Sections For Dissociative Electron Attachment To Sf5cf3, K. Graupner, L. M. Graham, T. A. Field, Christopher A. Mayhew, Ilya I. Fabrikant, T. M. Miller, M. Braun, M.-W. Ruf, Harmut Hotop

Ilya Fabrikant Publications

Using two complementary experimental methods, we have measured partial (mass-resolved) cross-sections for dissociative electron attachment to the molecule trifluoromethyl sulfurpentafluoride (SF₅CF₃) at the gas temperature T_G = 300K over a broad range of electron energies (E = 0.001–12 eV).

Relativistic Magnetic Monopole Flux Constraints From Rice, Daniel P. Hogan, Dave Z. Besson, John P. Ralston, Ilya Kravchenko, D. Seckel

Department of Physics and Astronomy: Faculty Publications

We report an upper limit on the flux of relativistic monopoles based on the nonobservation of in-ice showers by the Radio Ice Cherenkov Experiment (RICE) at the South Pole. We obtain a 95% C.L. limit of order 10^-18(cm² s sr)^-1 for intermediate-mass monopoles of 10⁷ ≤ γ ≤ 10¹² at the anticipated energy E_tot = 10¹⁶ GeV. This bound is over an order of magnitude stronger than all previously published experimental limits for this range of boost parameters γ and exceeds 2 orders of magnitude improvement over most of the range. We …

Thermodynamics Of Itinerant Magnets In A Classical Spin-Fluctuation Model, Aleksander L. Wysocki, James K. Glasbrenner, Kirill D. Belashchenko

Department of Physics and Astronomy: Faculty Publications

Thermodynamics of itinerant magnets is studied using a classical model with one parameter characterizing the degree of itinerancy. Monte Carlo simulations for bcc and fcc lattices are compared with the mean-field approximation and with the Onsager cavity field approximation extended to itinerant systems. The qualitative features of thermodynamics are similar to the known results of the functional integral method. It is found that magnetic short-range order is weak and almost independent on the degree of itinerancy, and the mean-field approximation describes the thermodynamics reasonably well. Ambiguity of the phase space measure for classical models is emphasized. The Onsager cavity field …

When Does Nitrate Become A Risk For Humans?, David S. Powlson, Tom M. Addiscott, Nigel Benjamin, Kenneth G. Cassman, Theo M. De Kok, Hans Van Grinsven, Jean-Louis L'Hirondel, Alex A. Avery, Chris Van Kessel

Department of Agronomy and Horticulture: Faculty Publications

Is nitrate harmful to humans? Are the current limits for nitrate concentration in drinking water justified by science? There is substantial disagreement among scientists over the interpretation of evidence on the issue. There are two main health issues: the linkage between nitrate and (i) infant methaemoglobinaemia, also known as blue baby syndrome, and (ii) cancers of the digestive tract. The evidence for nitrate as a cause of these serious diseases remains controversial. On one hand there is evidence that shows there is no clear association between nitrate in drinking water and the two main health issues with which it has …

Importance And Effect Of Nitrogen On Crop Quality And Health, Jürg Blumenthal, David D. Baltensperger, Kenneth G. Cassman, Stephen Mason, Alexander Pavlista

Department of Agronomy and Horticulture: Faculty Publications

Nitrogen (N) is often the most limiting factor in crop production. Hence, application of fertilizer nitrogen results in higher biomass yields and protein yield and concentration in plant tissue is commonly increased. Nitrogen often affects amino acid composition of protein and in turn its nutritional quality. In cereals, abundant supply of nitrogen decreases the relative proportion of lysine and threonine, thus, reducing the biological value of the protein. Increasing nitrogen supply generally improves kernel integrity and strength, resulting in better milling properties of the grain. In oil seed crops, protein levels are increased upon nitrogen fertilization, whereas oil concentration is …

Harvester Ant Nests Improve Recovery Performance Of Drought Impacted Vegetation In Grazing Regimes Of Semiarid Savanna, Texas, Nancy Nicolai, Fred Smeins, Jerry Cook

Department of Agronomy and Horticulture: Faculty Publications

Vegetation composition is often dictated by grazing intensity in semiarid savannas; recovery following drought may depend on pre drought species composition. Nests of the red harvester ant, Pogonomyrmex barbatus, affect the dynamics, composition and recovery of post drought communities due to their larger size, greater seed production and higher perennial grass richness. We hypothesized that vegetation at ant nests would survive drought and recover faster than vegetation in the surrounding grasslands, but that individual and population recovery would depend on plant species composition, which, in turn, would be influenced by grazing intensity. We assessed nest influence on density, cover, …
