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, …

Researching African Women And Gender Studies: New Social Science Perspectives, Akosua Adomako Ampofo, Josephine Beoku-Betts, Mary J. Osirim

Sociology Faculty Research and Scholarship

Research on African women and gender studies has grown substantially to a position where African-centered gender theories and praxis contribute to theorizing on global feminist scholarship. Africanist scholars in this field have explored new areas such as transnational and multiracial feminisms, both of which address the complex and interlocking conditions that impact women's lives and produce oppression, opportunity and privilege. In addition, emergent African-centered research on women and gender explores those critical areas of research frequently addressed in the global North which have historically been ignored or marginalized in the African context such as family, work, social and political movements, …

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 …

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 …

Grid Connection Requirements And Solutions For Dfig Wind Turbines, Wei Qiao, Ronald G. Harley

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) …

Branching Of Fungal Hyphae: Regulation, Mechanisms And Comparison With Other Branching Systems, Steven D. Harris

Department of Plant Pathology: Faculty Publications

The ability of rapidly growing hyphae to generate new polarity axes that result in the formation of a branch represents one of the most important yet least understood aspects of fungal cell biology. Branching is central to the development of mycelial colonies and also appears to play a key role in fungal interactions with other organisms. This review presents a description of the two major patterns of hyphal branching, apical and lateral, and highlights the roles of internal and external factors in the induction of branch formation. In addition, potential mechanisms underlying branch site selection are outlined, and the possible …

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).

Effect Of Sorghum Seedlings, And Previous Crop, On Soil Fluorescent Pseudomonas Spp., Deanna L. Funnell-Harris, Jeffrey Pedersen, David B. Marx

Department of Agronomy and Horticulture: Faculty Publications

Hypotheses in which sorghum seedlings [Sorghum bicolor (L.) Moench] of different genotypes will differentially modify soil microorganisms and will affect subsequent planting of wheat (Triticum aestivum L.) seedlings, were tested. Wheat cultivar Lewjain, and sorghum genotypes Redlan and RTx433, were planted into soils previously planted with wheat or sorghum in growth chamber experiments. Total culturable fungi and oomycetes, and fluorescent Pseudomonas spp. numbers (cfu) were determined. Pseudomonads were screened for hydrogen cyanide (HCN) production, for the presence of the phlD gene for 2,4-diacetylphloroglucinol production (Phl) and for a region of the operon involved in phenazine-1-carboxylic acid (PCA) production. …

Rural schools are facing a number of challenges. Common concerns among rural schools are poverty, changing demographics, and declining numbers. They are also faced with the issues of accountability and mandates from No Child Left Behind. The …

Whole-Plant Mineral Partitioning Throughout The Life Cycle In Arabidopsis Thaliana Ecotypes Columbia, Landsberg Erecta, Cape Verde Islands, And The Mutant Line Ysl1ysl3, Brian M. Waters, Michael A. Grusak

Department of Agronomy and Horticulture: Faculty Publications

Minimal information exists on whole-plant dynamics of mineral flow through Arabidopsis thaliana or on the source tissues responsible for mineral export to developing seeds. Understanding these phenomena in a model plant could help in the development of nutritionally enhanced crop cultivars. A whole-plant partitioning study, using sequential harvests, was conducted to characterize growth and mineral concentrations and contents of rosettes, cauline leaves, stems, immature fruit, mature fruit hulls, and seeds of three WT lines (Col-0, Ler, and Cvi) and one mutant line (Col-0::ysl1ysl3). Shoot mineral content increased throughout the life cycle for all minerals, although tissue-specific …

Pea Aphid, Jennifer A. Brisson, Gregory K. Davis

School of Biological Sciences: Faculty Publications

Aphids have long been of interest because of their complex life cycles, environmentally induced morphologies, and importance to agriculture. However, only recently has the resulting wealth of ecological and population genetic data begun to be supplemented by genomic and genetic mapping approaches. In 2004, the International Aphid Genomics Consortium, a collaboration of aphid researchers, chose to establish the pea aphid, Acyrthosiphon pisum, as the aphid of choice for the development of genomic resources. Here we introduce the pea aphid and discuss a number of biological questions for which the species is well suited. We then review previous mapping and quantitative …

Interspecific Demographic Trade-Offs And Soil-Related Habitat Associations Of Tree Species Along Resource Gradients, Sabrina E. Russo, Patrick Brown, Sylvester Tan, Stuart J. Davies

School of Biological Sciences: Faculty Publications

Summary

1. Interspecific relationships between fundamental demographic rates, often called demographic trade-offs, emerge from constraints within individuals related to morphology, physiology and resource allocation. Plant species that grow fast in high light usually have high mortality in shade, and this well-established relationship in part defines a species’ successional niche. More generally, this relationship represents a trade-off between a species’ ability to grow quickly to exploit abundant resources vs. avoiding mortality when resources are less plentiful, but few studies have described this demographic trade-off with respect to environmental factors other than light.

2. Using demographic data from 960 tree species in …

Ecological Genomics: Understanding Gene And Genome Function In The Natural Environment, M. C. Ungerer, L. C. Johnson, M. A. Herman

School of Biological Sciences: Faculty Publications

The field of ecological genomics seeks to understand the genetic mechanisms underlying responses of organisms to their natural environments. This is being achieved through the application of functional genomic approaches to identify and characterize genes with ecological and evolutionary relevance. By its very nature, ecological genomics is an interdisciplinary field. In this review, we consider the significance of this new area of study from both an ecological and genomic perspective using examples from the recent literature. We submit that by considering more fully an ecological context, researchers may gain additional insights into the underlying genetic basis of ecologically relevant phenotypic …

Investigation Of Millimetre Wave Generation By Stimulated Brillouin Scattering For Radio Over Fibre Applications, Markus Junker
