Impact Of Comorbidity In Prevention Of Adolescent Depressive Symptoms., Patrick Pössel, Simone Seemann, Martin Hautzinger Jan 2008

Impact Of Comorbidity In Prevention Of Adolescent Depressive Symptoms., Patrick Pössel, Simone Seemann, Martin Hautzinger

Faculty and Staff Scholarship

Despite the well-known relevance of comorbidity, few studies have examined the impact of comorbid anxiety or externalizing symptoms on the prevention of depressive symptoms in adolescents. To replicate earlier positive effects of a cognitive-behavioral prevention program of depressive symptoms and to test the hypothesis that the prevention program would be less effective in adolescents with comorbid anxiety and externalizing symptoms, a study was conducted involving 301 8th-grade students, randomly divided into an intervention group and a non-intervention control group. The randomized design included baseline, post-intervention, and 6-month follow-up. The prevention program included 10 sessions held in a regular school setting. …


Reassessing Accounting Faculty Scholarly Expectations: Journal Classification By Author Affiliation, Alan N. Attaway, Sidney J. Baxendale, Benjamin P. Foster, Julia N. Karcher Jan 2008

Reassessing Accounting Faculty Scholarly Expectations: Journal Classification By Author Affiliation, Alan N. Attaway, Sidney J. Baxendale, Benjamin P. Foster, Julia N. Karcher

Faculty and Staff Scholarship

An extensive literature exists that determines accounting journal rankings and top research producers both individually and by program. While this research stream provides valuable insights to the Association to Advance Collegiate Schools of Business International (AACSB) accredited programs and to programs working to achieve such accreditation, it frequently is based on quality perceptions or considers top-rated programs only. This study extends previous research by reviewing authorship by faculty at a wider range of institutions. The results of this study suggest that lists based on the “top” journals may be unrealistic for many institutions. The information provided in this manuscript should …


X-Ray Fluorescence And Neutron Activation Analysis Of Obsidian From The Red Sea Coast Of Eritrea, Michael D. Glascock, Amanuel Beyin, Magen E. Coleman Jan 2008

X-Ray Fluorescence And Neutron Activation Analysis Of Obsidian From The Red Sea Coast Of Eritrea, Michael D. Glascock, Amanuel Beyin, Magen E. Coleman

Faculty and Staff Scholarship

The strategic location of Eritrea along the Red Sea coast and the Horn of Africa makes it an important place to study human prehistory over a long span of time. However, recurrent political instability and the environmental adversity in the region have hindered comprehensive archaeological investigation. Paleolithic research in Eritrea began after the country obtained independence from Ethiopia in 1991. Geological survey in the Abdur area, along the Gulf of Zula coast (Figure 1), identified Paleolithic artifacts embedded in reef limestone dating to ~ 125 Ka BP (Walter et al., 2000). Based on this evidence, human coastal adaptation during the …


Nicarbazin Bait Reduces Reproduction By Pigeons (Columba Livia), Michael L. Avery, Kandy L. Keacher, Eric A. Tillman Jan 2008

Nicarbazin Bait Reduces Reproduction By Pigeons (Columba Livia), Michael L. Avery, Kandy L. Keacher, Eric A. Tillman

United States Department of Agriculture Wildlife Services: Staff Publications

Development of effective methods for reducing populations of overabundant nuisance bird species continues to challenge wildlife biologists. Reproductive inhibition, although conceptually pleasing, has been difficult to implement because of the lack of a safe, approved avian contraceptive. Recently, however, nicarbazin received regulatory approval in the United States for use as a bait to decrease hatchability of resident Canada goose (Branta canadensis) and feral pigeon (Columba livia) eggs. In anticipation of the feral pigeon registration, we evaluated efficacy by exposing captive pairs of nesting pigeons to nicarbazin bait for 4 h daily. Egg production was unaffected, but …


Evaluation Of Aerial Cluster Sampling Of Double-Crested Cormorants On Aquaculture Ponds In Mississippi, Brian S. Dorr, Loren W. Burger Jr., Scott C. Barras Jan 2008

Evaluation Of Aerial Cluster Sampling Of Double-Crested Cormorants On Aquaculture Ponds In Mississippi, Brian S. Dorr, Loren W. Burger Jr., Scott C. Barras

United States Department of Agriculture Wildlife Services: Staff Publications

Concern over increasing numbers of double-crested cormorants (Phalacrocorax auritus) and their impacts on channel catfish (Ictalurus punctatus) aquaculture has resulted in increased need for quantitative information to develop and evaluate depredation management efforts. We evaluated aerial surveys in a stratified cluster sampling (SCS) design to estimate and monitor abundance of cormorants on catfish aquaculture ponds in the Yazoo River Basin of Mississippi, USA (hereafter Yazoo Basin). Twice monthly abundance estimates and coefficient of variation during winter averaged 8,128 (n = 29, SE = 1,233) and 33% (n = 29, SE = 0.02), respectively. Counts of cormorants …

Skunk Rabies In California (1992–2003)—Implications For Oral Rabies Vaccination, Ray T. Sterner, Ben Sun, Jean B. Bourassa, Robert L. Hale, Stephanie A. Shwiff, Michele T. Jay, Dennis Slate

United States Department of Agriculture Wildlife Services: Staff Publications

Skunk-variant rabies is endemic in California (United States), and the development of oral vaccines and baits to vaccinate skunks is in progress. In 2003, the California Department of Public Health (CDPH) began to quantify the impacts of skunk-variant rabies and to assess the feasibility of using oral rabies vaccination (ORV) as a containment measure. The CDPH rabies case data for skunks were spatially depicted and analyzed using a geographic information system. Statewide, rabid skunks (1992–2003) primarily occurred in seven physiographic regions: Central Coast, North Coast, North Sierra, Sacramento Valley, San Francisco Bay and Delta, San Joaquin Valley, and South Sierra. …


Accounting For City Real Exchange Rate Changes In India, Scott Gilbert, A. K. M. Mahbub Morshed Jan 2008

Accounting For City Real Exchange Rate Changes In India, Scott Gilbert, A. K. M. Mahbub Morshed

Economics Discussion Papers

We examine the role of non-traded goods in the city real exchange rate changes in India. Using the Mean Squared Error (MSE) decomposition we find that non-traded goods explain about 30% of the variation of the Indian city real exchange rate changes, rather than the small amount found in other cross-country studies. We also analyze the role of consumption elasticity of substitution between traded and non-traded goods.


Career And Family Choices In The Presence Of Uncertainty, Alison Watts Jan 2008

Career And Family Choices In The Presence Of Uncertainty, Alison Watts

Economics Discussion Papers

It is well known that women's career outcomes are tied to fertility decisions and that occasionally educated women who had planned to stay in the labor market after childbirth exit the market. We examine women's career, fertility, and educational choices in an environment of uncertainty regarding the possibility of achieving both a high-powered career and a family. In a simple framework, we show that although women may prefer to have both a prestigious career and a family they may choose a less prestigious job or no family due to the uncertainty involved in being able to achieve both a career …


Quantum Phases For A Generalized Harmonic Oscillator, Paul Bracken Jan 2008

Quantum Phases For A Generalized Harmonic Oscillator, Paul Bracken

School of Mathematical & Statistical Sciences Faculty Publications

An effective Hamiltonian for the generalized harmonic oscillator is determined by using squeezed state wavefunctions. The equations of motion over an extended phase space are determined and then solved perturbatively for a specific choice of the oscillator parameters. These results are used to calculate the dynamic and geometric phases for the generalized oscillator with this choice of parameters.


Ambivalence About Social Welfare : An Evaluation Of Measurement Approaches., Jason Gainous Jan 2008

Ambivalence About Social Welfare : An Evaluation Of Measurement Approaches., Jason Gainous

Faculty and Staff Scholarship

Research across disciplines, including political science, has embraced the idea that individuals often possess ambivalent attitudes, but there is considerable disagreement about how to measure ambivalence. Determining an effective way of capturing such phenomena is important to our understanding of politics and public opinion. The literature offers several meta-attitudinal and operative measures of ambivalence. I discuss strengths and weaknesses of each of these approaches and conduct a test of the relative construct validity of two meta-attitudinal and two operative measures of social welfare ambivalence using data from a statewide survey of Florida residents in 2004. The findings suggest that one …

Searching For The Majority: Algorithms Of Voluntary Control, Jin Fan, Kevin G. Guise, Xun Liu, Hongbin Wang

Faculty, Staff and Student Publications

Voluntary control of information processing is crucial to allocate resources and prioritize the processes that are most important under a given situation; the algorithms underlying such control, however, are often not clear. We investigated possible algorithms of control for the performance of the majority function, in which participants searched for and identified one of two alternative categories (left or right pointing arrows) as composing the majority in each stimulus set. We manipulated the amount (set size of 1, 3, and 5) and content (ratio of left and right pointing arrows within a set) of the inputs to test competing hypotheses …


Urban Watershed/Water Body Restoration - The Driving Forces, Vladimir Novotny, David E. Clark, Robert J. Griffin Jan 2008

Urban Watershed/Water Body Restoration - The Driving Forces, Vladimir Novotny, David E. Clark, Robert J. Griffin

Economics Faculty Research and Publications

Urban streams are used for several purposes. Some uses are conflicting and some are complementary. The use of urban water bodies and the resolution of conflicts is driven by anthropogenic and biocentric/ecocentric interests that must be optimized and the conflicts resolved. This article examines and analyzes land ethics (biocentric) and socio-economic (anthropocentric) drives for stream restoration of urban watersheds located in the Milwaukee (WI) metropolitan area. The basins experienced increased flooding, significant degradation of sediment and water quality, and loss of aquatic species, all due to urbanization. It was found that the primary drivers for restoration of urban streams are …


Loyalists In War, Americans In Peace: The Reintegration Of The Loyalists, 1775-1800, Aaron N. Coleman Jan 2008

Loyalists In War, Americans In Peace: The Reintegration Of The Loyalists, 1775-1800, Aaron N. Coleman

University of Kentucky Doctoral Dissertations

After the American Revolution a number of Loyalists, those colonial Americans who remained loyal to England during the War for Independence, did not relocate to the other dominions of the British Empire. Instead, they sought to return to their homes and restart their lives. Despite fierce opposition to their return from all across the Confederation, their attempts to become part of a newly independent America were generally successful. Thus, after several years of struggle most former Loyalists who wanted to return were able to do so.

Various studies have concentrated on the wartime activities of Loyalists, but few have examined …


Role Of The Reactive Oxygen Species Peroxynitrite In Traumatic Brain Injury, Ying Deng Jan 2008

Role Of The Reactive Oxygen Species Peroxynitrite In Traumatic Brain Injury, Ying Deng

University of Kentucky Doctoral Dissertations

Reactive oxygen species (ROS) is cytotoxic to the cell and is known to contribute to secondary cell death following primary traumatic brain injury (TBI). We described in our study that PN is the main mediator for both lipid peroxidation and protein nitration, and occurred almost immediately after injury. As a downstream factor to oxidative damage, the peak of Ca2+-dependent, calpainmediated cytoskeletal proteolysis preceded that of neurodegeneration, suggesting that calpain-mediated proteolysis is the common pathway leading to neuronal cell death. The time course study clearly elucidated the interrelationship of these cellular changes following TBI, provided window of opportunity for pharmacological intervention. …


Surfactant And Metal Sorption Studies By Functionalized Membranes And Quartz Crystal Microbalance, Abhay R. Ladhe Jan 2008

Surfactant And Metal Sorption Studies By Functionalized Membranes And Quartz Crystal Microbalance, Abhay R. Ladhe

University of Kentucky Doctoral Dissertations

Functionalized membranes provide an elegant platform for selective separations and sorptions. In this dissertation, application of functionalized membranes for surfactant and metal sorption studies are discussed. Sorption behavior of surfactants is also studied using quartz crystal microbalance (QCM) and other techniques.

Adsorption of the ethoxylated surfactants on polymeric materials (cotton and polyester) and model gold surface was quantified from a non-aqueous siloxane based solvent (D5) and water. The role of ethylene oxide group and the effect of nature of polymeric materials on adsorption behavior was quantified and established. In the case of gold-water interface, the adsorption data was fitted to …


Linking The Structure And Mechanical Behavior Of Nanoporous Gold, Ye Sun Jan 2008

Linking The Structure And Mechanical Behavior Of Nanoporous Gold, Ye Sun

University of Kentucky Doctoral Dissertations

The structure of nanoporous gold (np-Au) provides a very limited volume for deformation to occur, and thus offers an opportunity to study the role of defects such as dislocations in nanoscale metal volumes. A practical goal is to understand mechanical properties of np-Au so that it can be can produced in stable form, for use in applications that require some mechanical integrity. Bulk and thin film np-Au have been fabricated and studied here.

Bulk np-Au was prepared by electrochemically dealloying Au-Ag alloys with 25 and 30 at.% Au. In the lower Au content material, cracks always formed during dealloying. When …


God’S Littlest Children And The Right To Live: The Case For A Positivist Pro-Life Overturning Of Roe, Raymond B. Marcin Jan 2008

God’S Littlest Children And The Right To Live: The Case For A Positivist Pro-Life Overturning Of Roe, Raymond B. Marcin

Scholarly Articles

For those who understand that God's littlest children have the same right to life that all God's children have, the day on which the United States Supreme Court decided Roe v. Wade was a day that echoed the grief and frustration that, more than a century earlier, accompanied the decision in Dred Scott v. Sandford. And the day on which the United States Supreme Court decides to overturn Roe v. Wade and all the other pro-abortion decisions will be a day of heart-felt thanksgiving. From the pro-life perspective, however, it will not be enough, that the Supreme Court merely overturns …

Social Justice And Health Care Management: An Elusive Quest?, George P. Smith Ii Jan 2008

Social Justice And Health Care Management: An Elusive Quest?, George P. Smith Ii

Scholarly Articles

Contemporary debate on health care resource management is tied to a central moral issue: namely, how to achieve an optimum level of reasonable or appropriate treatment based on the medical condition of each patient. Failing to tackle and resolve this issue in a confident and forthright manner assures the present approach to health care decision making to continue in a state of indecisiveness if, indeed, not lethargy.

Undergirding this moral issue is the foundational economic dilemma of controlling costs while limiting access to health care resources. Finding a just solution to an equitable distribution of finite health care resources is …


Milk Teeth And Jet Planes: Kin Relations In Families Of Sri Lanka’S Transnational Domestic Servants, Michele Ruth Gamburd Jan 2008

Milk Teeth And Jet Planes: Kin Relations In Families Of Sri Lanka’S Transnational Domestic Servants, Michele Ruth Gamburd

Anthropology Faculty Publications and Presentations

This essay examines the confluence of local and global dynamics, exploring how transnational migration affects and is affected by gender roles, kinship relations, intergenerational obligations, and ideologies of parenthood. Journeying to the Middle East repeated on two-year labor contracts, many of Sri Lanka’s migrant housemaids leave behind their husbands and children. Women’s long-term absences reorganize and disrupt widely accepted gendered attributions of parenting roles, with fathers and female relatives taking over household tasks. Migrants say that economic difficulties prompt migration, and assess commitment to kin in financial terms. The government also benefits from remittances. Nevertheless, stakeholders (villagers, politicians, and the …


Large Domestic Pits On The Northwest Coast Of North America, Kenneth M. Ames, Cameron M. Smith, Alexander Bourdeau Jan 2008

Large Domestic Pits On The Northwest Coast Of North America, Kenneth M. Ames, Cameron M. Smith, Alexander Bourdeau

Anthropology Faculty Publications and Presentations

Excavations of prehistoric and contact-period houses on the southern Northwest Coast of North America have exposed very large interior pit complexes. The complexes are either long trenches or rows of pits beneath the house floors. They are associated with substantial permanently occupied houses dated to between 300 CAL B.G. and A.D. 1830. The pits add significantly to the storage potentials of these houses and suggest surplus production.

Evaluation Of Stop-Level Vs. Route-Level Breeding Bird Survey Counts For Modeling The Influence Of Land Use And Climate On Breeding Blackbird Abundance In North Dakota, Michelle L. Petersen, George M. Linz, Greg Forcey, Wayne Thogmartin, William J. Bleier Jan 2008

Evaluation Of Stop-Level Vs. Route-Level Breeding Bird Survey Counts For Modeling The Influence Of Land Use And Climate On Breeding Blackbird Abundance In North Dakota, Michelle L. Petersen, George M. Linz, Greg Forcey, Wayne Thogmartin, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

The Red-winged Blackbird (Agelaius phoeniceus), Yellow-headed Blackbird (Xanthocephalus xanthocephalus), and Common Grackle (Quiscalus quiscula) are the three most abundant blackbird species (Icteridae) found in North Dakota and comprise almost 10% of its avian population (Stewart and Kantrud 1972). Blackbird abundance combined with their food habitats make them significant agricultural pests on sunflower. Cost estimates for blackbird damage to sunflower in the North Dakota are likely over $10 million dollars annually (Kleingartner, pers. comm). Because of this economic impact blackbirds have on agriculture, it is important to understand land use and climatic factors influencing blackbird …


Development Of Polymorphic Microsatellite Loci For The Common Vampire Bat, Desmodus Rotundus (Chiroptera: Phylostomidae), Antoinette J. Piaggio, John J. Johnston, Susan L. Perkins Jan 2008

Development Of Polymorphic Microsatellite Loci For The Common Vampire Bat, Desmodus Rotundus (Chiroptera: Phylostomidae), Antoinette J. Piaggio, John J. Johnston, Susan L. Perkins

United States Department of Agriculture Wildlife Services: Staff Publications

The common vampire bat (Desmodus rotundus) is one of three haematophagous species of bats and the only species in this genus. These New World bats prey on mammals and create significant economic impacts through transmission of rabies in areas where livestock are prevalent. Furthermore, in some portions of their range, it is not uncommon for them to prey upon humans. It is critical to the management of this species and for understanding the spread of bat rabies that detailed studies of D. rotundus population structure be conducted. To further such studies, we have characterized 12 microsatellite loci for …

United States Department of Agriculture Wildlife Services: Staff Publications

Thirteen microsatellite loci were isolated from the coqui frog (Eleutherodactylus coqui) and optimized for future research. The loci were screened across 37 individuals from two Puerto Rican populations. Loci were variable with the number of alleles per locus ranging from three to 38. Polymorphic information content ranged from 0.453 to 0.963 and observed heterozygosity for each population ranged from 0.320 to 0.920.


Evaluation Of An Electrified Mat As A White-Tailed Deer (Odocoileus Virginianus) Barrier, Thomas W. Seamans, David A. Helon Jan 2008

Evaluation Of An Electrified Mat As A White-Tailed Deer (Odocoileus Virginianus) Barrier, Thomas W. Seamans, David A. Helon

United States Department of Agriculture Wildlife Services: Staff Publications

White-tailed deer (Odocoileus virginianus) pose economic and safety problems for agricultural and transportation industries. We tested an electronic mat to determine if it would reduce deer crossing through fence openings. We measured deer intrusions and corn consumption at five sites with charged mats and five sites with non-charged mats. Weekly intrusions at treated sites decreased an average of 95% from pre-treatment. Weekly intrusions at control sites were reduced 60% during weeks 1 and 2 and increased to 10% reduction by week 6. Weekly corn consumption at treated sites decreased from pretreatment through all treatment weeks. Weekly corn consumption …

United States Department of Agriculture Wildlife Services: Staff Publications

Problem: An effective, single-injection, multi-year, GnRH contraceptive agent is needed to control reproduction in overabundant white-tailed deer populations.

Method of study: Two GnRH conjugates, GonaConTM (GnRH–KLH) and GonaCon-BTM (GnRH–blue protein), were prepared in emulsion form as one-injection and two-injection immunocontraceptive vaccine formulations. In addition, the GnRH–KLH protein conjugate was lyophilized and suspended in AdjuVacTM adjuvant to produce a fifth vaccine formulation. Each formulation was administered to a group of five captive adult female white-tailed deer. Reproductive performance of treated female deer was monitored for 5 years to determine the comparative efficacy of the various treatments.

Results: The …

Deer Impact On Vegetation In Natural Areas In Southeastern Nebraska, Joseph Gubanyi, Julie A. Savidge, Scott E. Hygnstrom, Kurt C. Vercauteren, Gary W. Garabrandt, Seth Korte

United States Department of Agriculture Wildlife Services: Staff Publications

We studied the effect of browsing by white-tailed deer (Odocoileus virginianus Zimmerman) on vegetation at three sites with high densities of deer and six sites with low densities of deer along the Missouri and Platte Rivers in southeastern Nebraska in 1995-1996. Vegetation volume from 0-1 m high was similar between sites with high and low deer densities (P > 0.05). From 1-2 m high, vegetation volume was less at sites with more deer in both years (P < 0.05). Densities for eight of 11 small woody plant categories (< 3 cm dbh) were less common at sites with high densities of deer (P < 0.05). Overall densities of small trees (3-15 cm dbh) were similar between sites with high and low densities of deer. However, small hackberry trees (Celtis occidentalis L.) were more common (P = 0.03), while all other small trees were less common (P = 0.038), at sites with …

United States Department of Agriculture Wildlife Services: Staff Publications

We designed and developed a vehicle-mounted very high frequency–based telemetry system that integrated an on-board antenna, receiver, electronic compass, Global Positioning System, computer, and Geographic Information System. The system allows users to accurately and quickly obtain fixes, estimate and confirm locations of radio-marked animals, and immediately record data into an electronic spreadsheet or database. The total cost of materials to build the system was $7,349 (United States currency). Mean error angle of 2.63 ± 12.1° (SD; range =-33.7–42.2°) and mean location error distance of 128 ± 91.3 m (SD; range = 0–408 m) suggested precision and accuracy of our system …


Livestock Protection Dogs For Deterring Deer From Cattle And Feed, Kurt C. Vercauteren, Michael J. Lavelle, Gregory Phillips Jan 2008

Livestock Protection Dogs For Deterring Deer From Cattle And Feed, Kurt C. Vercauteren, Michael J. Lavelle, Gregory Phillips

United States Department of Agriculture Wildlife Services: Staff Publications

Disease transmission between wildlife and livestock is a worldwide issue. Society needs better methods to prevent interspecies transmission to reduce disease risks. Producers have successfully used livestock protection dogs (LPDs) for thousands of years to reduce predation. We theorized that LPDs raised and bonded with cattle could be used to also reduce risk of bovine tuberculosis (Myobacterium bovis; TB) transmission between white-tailed deer (Odocoileus virginianus) and cattle by minimizing contact between the 2 species and use of cattle feed by deer. We evaluated 4 LPDs over 5 months, utilizing 2 data collection methods (direct observation and …
