Fifteen Years Of Plant Community Dynamics During A Northwest Ohio Oak Savanna Restoration, Scott R. Abella, John F. Jaeger, Lawrence G. Brewer Jan 2004

Fifteen Years Of Plant Community Dynamics During A Northwest Ohio Oak Savanna Restoration, Scott R. Abella, John F. Jaeger, Lawrence G. Brewer

Public Policy and Leadership Faculty Research

Midwest oak savanna communities are noted for their unusual plant assemblages, but these communities have been reduced by more than 98% because of changing land uses and conversion to closed-canopy forests. We initiated an ongoing 15-year experiment in 1988 to restore a 40-ha black oak (Quercus velutina) savanna by applying burn treatments that historically maintained this vegetation type. Groundlayer composition changed significantly for both the burn treatment and the control, with the burn treatment exhibiting slight increases in herbs such as wild lupine (Lupinus perennis) and hairy puccoon (Lithospermum caroliniense), both of which are species requiring greater insolation. Burn treatments …

Studies In Cardiac Defribrillation, Eamonn Mckenna Jan 2004

Studies In Cardiac Defribrillation, Eamonn Mckenna

Masters

Cardiac disease resulting in cardiac arrest is one of the most common fatal diseases in the developed world. Defibrillation is the medical procedure used to correct the irregular cardiac rhythm (ventricular fibrillation (VF)) which is very often detected in patients suffering cardiac arrest. In the work reported in this thesis, two aspects of the defibrillation of patients in VF were examined. The first area of investigation concentrated on the use of multiple defibrillation electrodes to be used during closed chest (transthoracic) defibrillation. This study was carried out in a saline bath and centred on “focusing” electric fields from perimeter electrodes …

A Comparison Of Attitudes About Aggression, Sexuality And Social Support In The Peer Relationships Of Sexually Abused And Nonabused Female Adolescents, Sherri R. Edelman Jan 2004

A Comparison Of Attitudes About Aggression, Sexuality And Social Support In The Peer Relationships Of Sexually Abused And Nonabused Female Adolescents, Sherri R. Edelman

PCOM Psychology Dissertations

There is a paucity of research examining whether adolescents with a history of sexual abuse develop different norms or standards for acceptable behavior in their peer relationships. The trauma literature suggests that intervening variables such as perceived social support, interpretations of violence, and interpersonal attitudes may be relevant to the study of sexual abuse. The goal of this study was to examine the relationship between a history of sexual abuse, relational attitudes about aggression and sexuality, and the interpersonal factors of social support and negative interaction in adolescent peer relationships. Two groups of female subjects between 13 and 17 years …

Feasibility Study Of A Cognitive Behavioral Smoking Cessation Intervention For Adolescent Males In Residential Treatment, Flora Casallas Jan 2004

Feasibility Study Of A Cognitive Behavioral Smoking Cessation Intervention For Adolescent Males In Residential Treatment, Flora Casallas

PCOM Psychology Dissertations

The current study examined the effectiveness of a modified, empirically-based smoking cessation intervention, originally designed for teenagers in public school settings, but applied to actively smoking adolescents in residential treatment. The cognitive-behavioral intervention, developed by the American Lung Association (ALA, 2001) and researchers at West Virginia University, called Not-On-Tobacco (N-O-T), provides a total-health approach to helping teenagers quit smoking or to reducing the number of cigarettes smoked. The 10-session intervention was delivered over five consecutive weeks to eight adolescent males ranging in age 13 to 16 and in grades 8 to 10, living in a residential treatment community (RTC) located …

Role Of Motivation To Change On Treatment Outcome In Individuals With Anorexia Nervosa , Darlene Davis Link Jan 2004

Role Of Motivation To Change On Treatment Outcome In Individuals With Anorexia Nervosa , Darlene Davis Link

PCOM Psychology Dissertations

The present study investigated motivation to change as a factor in the treatment of Anorexia Nervosa. This study was conducted at The Renfrew Center with 44 adults diagnosed with Anorexia Nervosa who were entering their inpatient program. The participants were evaluated at intake and discharge on variables of motivation to change, eating disordered symptom severity, weight change, and compliance with treatment. As predicted, results revealed significant negative correlations between the patient's level of readiness to change at admission and perfectionism, distrust of others and their severity of anorexic symptoms at discharge. In addition, the results confirmed that the patient's level …

Supernatant Protein Factor: Insights Into Its Regulation And Ability To Stimulate Cholesterol Synthesis In Vitro And In Cell Culture, Vishwesh Mokashi Jan 2004

Supernatant Protein Factor: Insights Into Its Regulation And Ability To Stimulate Cholesterol Synthesis In Vitro And In Cell Culture, Vishwesh Mokashi

University of Kentucky Doctoral Dissertations

Supernatant protein factor (SPF) is a 46-kDa cytosolic protein that stimulates squalene monooxygenase, which catalyses the second committed step in cholesterol biosynthesis. The mechanism by which SPF stimulates this enzyme is not understood and the goal of these studies was to see if SPF affected cholesterol synthesis in cultured cells. Rat supernatant protein factor-like protein (SPF2) shares 77% sequence identity with human SPF. In my studies SPF2 also stimulated squalene monooxygenase in vitro and incubation of SPF2 with protein kinase A (PKA) and C increased its activity by about 2-fold, as shown earlier with SPF. GTP and GDP prevented the …

The Biological Basis Of Commitment: Does One Size Fit All?, Naomi R. Cahn, June Carbone Jan 2004

The Biological Basis Of Commitment: Does One Size Fit All?, Naomi R. Cahn, June Carbone

GW Law Faculty Publications & Other Works

Understanding the biological roots of intimate behavior is a complex undertaking that involves the integration of evolutionary biology, evolutionary psychology, neuroscience, anthropology and sociology. Evolutionary biology describes theories that explain the persistence of certain types of behavior in terms of presumed evolutionary pressures or advantages, focusing on the human mind. Evolutionary biologists assume that behavior that maximizes the presence of associated genes in the next generation is the behavior most likely to persist. In this paper, we take the growing insights that arise from the study of the biology of attachment to frame the emerging policy choices underlying the governance …

Assessing The Legality Of Invading Iraq, Sean D. Murphy Jan 2004

Assessing The Legality Of Invading Iraq, Sean D. Murphy

GW Law Faculty Publications & Other Works

The recent invasion of Iraq challenges a cornerstone of contemporary international law: the prohibition on the use of force by one state against another state. The conventional wisdom is that the United States embarked on the invasion with little regard for international law or for the attitudes reflected by other nations, including the other members of the UN Security Council. This article disputes that conventional wisdom.

First, the Bush administration could have ignored international law and the Security Council, but in fact deployed a fairly sophisticated legal theory as to why U.S. actions were permissible under international law, a theory …

A Delicate Task: Balancing The Rights Of Children And Mothers In Parental Termination Proceedings, Catherine J. Ross Jan 2004

A Delicate Task: Balancing The Rights Of Children And Mothers In Parental Termination Proceedings, Catherine J. Ross

GW Law Faculty Publications & Other Works

This article considers the independent liberty interests of children in foster care and their mothers in parental termination proceedings. Federal reforms enacted in 1997 impose a mandatory deadline for the state to terminate parental rights. That policy erroneously presumes that the passage of time suffices to establish parental fault and satisfies a parent's due process rights to her child. The policy also fails to protect the minority of children in foster care who assert an interest in preserving a safe relationship with mothers who are unlikely to regain custody within the state's time frame - including many substance abusers, incarcerated …

Formation Of A Stress-Induced Check Mark On The Otoliths Of Juvenile Fishes: Implications For Mesocosm Studies, Thomas R. Reinert, Donald M. Baltz Jan 2004

Formation Of A Stress-Induced Check Mark On The Otoliths Of Juvenile Fishes: Implications For Mesocosm Studies, Thomas R. Reinert, Donald M. Baltz

Gulf and Caribbean Research

Daily otolith increment widths of spot Leiostomus xanthurus and spotted seatrout Cynoscion nebulosus were examined experimentally in field mesocosms for 5 to 7 days in various habitat types. Daily otolith increments were used as a surrogate for daily somatic growth so that growth prior to capture and handling could be examined. For both species, possible effects of habitat types were confounded by an overall decrease in daily increment widths during the experimental period when compared to increment widths prior to capture. Several spotted seatrout inadvertently captured during mesocosm deployment provided a means for assessing if there was a significant mesocosm …

The First Larval Stage Of Microprosthema Semilaeve (Von Martens, 1872) (Crustacea: Decapoda: Stenopodidea) Obtained In The Laboratory, Joel W. Martin, Joseph W. Goy Jan 2004

The First Larval Stage Of Microprosthema Semilaeve (Von Martens, 1872) (Crustacea: Decapoda: Stenopodidea) Obtained In The Laboratory, Joel W. Martin, Joseph W. Goy

Gulf and Caribbean Research

The first larval stage of Microprosthema semilaeve (von Martens, 1872) is described from ovigerous females collected off Sombrero Key, Florida Keys, USA, and Guana Island, British Virgin Islands, Caribbean. The larvae are characterized by a broad, triangular telson bearing posterolateral spines and an “anomuran seta,” a first maxilliped that differs markedly from the very similar (to each other) second and third maxillipeds, and the presence of the first pereiopod as a swimming appendage upon hatching, as is apparently true of all stenopodidean first stage larvae. Characters of the larvae are compared to those described from the Indian Ocean by Raje …

Stomatopoda (Crustacea: Hoplocarida) From The Shallow, Inshore Waters Of The Northern Gulf Of Mexico (Apalachicola River, Florida To Port Aransas, Texas), John M. Foster, Brent P. Thoma, Richard W. Heard Jan 2004

Stomatopoda (Crustacea: Hoplocarida) From The Shallow, Inshore Waters Of The Northern Gulf Of Mexico (Apalachicola River, Florida To Port Aransas, Texas), John M. Foster, Brent P. Thoma, Richard W. Heard

Gulf and Caribbean Research

Six species representing the order Stomatopoda are reported from the shallow, inshore waters (passes, bays, and estuaries) of the northern Gulf of Mexico limited to a depth of 10 m or less, and by the Apalachicola River (Florida) in the east and Port Aransas (Texas) in the west. With the exception of the “live bottom” gonodactylid, Neogonodactylus bredini (Manning), these predatory crustaceans usually inhabit burrows in mud, sand-mud, and sand substrata in coastal and shelf waters. The species treated in this paper are Neogonodactylus bredini (Manning), Lysiosquilla scabricauda (Lamarck), Bigelowina biminiensis (Bigelow), Coronis scolopendra Latreille, Squilla empusa Say, and Gibbesia …

First Record Of Bonefish, Albula Vulpes, From Mississippi Coastal Waters, K.J. Cuevas, James S. Franks, M.V. Buchanan Jan 2004

First Record Of Bonefish, Albula Vulpes, From Mississippi Coastal Waters, K.J. Cuevas, James S. Franks, M.V. Buchanan

Gulf and Caribbean Research

Bonefish (Albula spp.), Family Albulidae, occur worldwide in coastal waters of tropical and warm temperate seas (Crabtree et al. 1997), and 2 species, A. vulpes and A. nemoptera, are recognized from the western Atlantic Ocean (Rivas and Warlen 1967). The normal range of A. vulpes in the western Atlantic extends from Bermuda to Brazil, including the Bahamas, Cuba, Mexico, Central America and the Antilles (Hildebrand 1963), but in US waters, A. vulpes typically occurs off south Florida (Crabtree et al. 1997). In contrast, A. nemoptera has been reported from Panama, Colombia, Venezuela, Jamaica and Hispaniola (Uyeno et al. …

Notes On Aquarium Brood Release And Feeding Of The Opossum Pipefish, Microphis Brachyurus Lineatus, Sarah Frias-Torres Jan 2004

Notes On Aquarium Brood Release And Feeding Of The Opossum Pipefish, Microphis Brachyurus Lineatus, Sarah Frias-Torres

Gulf and Caribbean Research

The opossum pipefish, Microphis brachyurus lineatus, is a migratory syngnathid with a salmon-like life history (Frias-Torres 2002). Adults breed in freshwater and oligohaline habitats associated with emergent vegetation, mostly Panicum sp. and Polygonum sp.; breeding occurs during the wet season (May to November) (Gilmore and Hastings 1983). In southern Mexico, opossum pipefish associate with Ruppia maritima, and reproduction is year-round (Miranda-Marure et al. 2004). Pelagic juveniles are found in the Atlantic Ocean and are associated with Sargassum sp. (Böhlke and Chaplin 1968). Juveniles eventually recruit into oligohaline habitats. The species range is from Sao Paulo, Brazil, to New …

Predators And The Distribution And Abundance Of Blennies On Offshore Petroleum Platforms, Tommy J. Rauch Jan 2004

Predators And The Distribution And Abundance Of Blennies On Offshore Petroleum Platforms, Tommy J. Rauch

Gulf and Caribbean Research

Predation may be important in structuring fish assemblages but studies of the intensity of predation on marine fish assemblages are uncommon. Predator avoidance behavior was used to identify the predators of an assemblage of blennies found on offshore petroleum platforms in the northern Gulf of Mexico. The distribution of predators was then compared with the distribution of 3 species of blennies to see if predation intensity was related to the vertical zonation of blennies. Predator approaches and blenniid activity were compared in low and high surface current events. Results did not support a hypothesis of predation controlling the distribution and …

Sometimes, Practice Makes Imperfect: Overcoming The Automaticity Of Challenging Behavior By Linking Intervention To Thoughts, Feelings, And Action, Robert A. Gable, Richard Van Acker Jan 2004

Sometimes, Practice Makes Imperfect: Overcoming The Automaticity Of Challenging Behavior By Linking Intervention To Thoughts, Feelings, And Action, Robert A. Gable, Richard Van Acker

Communication Disorders & Special Education Faculty Publications

In schools throughout the country, education personnel express concern over the aggressive and antisocial behavior of children and youth. The frequency and severity of these acts compel us to find more effective strategies for decreasing and eliminating these behaviors. In this article, we argue for a broader explanation of the nature and treatment of aggressive behavior, especially when it rises to what is essentially an automotive response level. We contend that both assessment and intervention must account for internal and external influences on behavior and that treatment should encompass cognitive, affective, and behavioral dimensions of the problem. Finally, we discuss …

Perspectives On Attention Deficit Hyperactivity Disorder: Executive Functions, Working Memory, And Language Disabilities, Carol Westby, Silvana Watson Jan 2004

Perspectives On Attention Deficit Hyperactivity Disorder: Executive Functions, Working Memory, And Language Disabilities, Carol Westby, Silvana Watson

Communication Disorders & Special Education Faculty Publications

The conceptualization of the nature of attention deficit hyper-activity disorder (ADHD) has changed in the last decade. ADHD is now viewed as a neurologically based condition with primary deficits in executive functions and working memory (WM). Students with ADHD have deficits in discourse organization, inferring, and monitoring that are related to their executive function and WM deficits. A large number of students with ADHD also have comorbid reading and language disabilities that exist in addition to the deficits directly associated with the ADHD. Comprehensive evaluation of students with ADHD is essential to address their specific learning needs

On The Ecological Status Of The Concept "Boundary Conditions" - A Few Methodological Remarks, Lubomira Burchardt, Krzystof Lastowski, Harold G. Marshall Jan 2004

On The Ecological Status Of The Concept "Boundary Conditions" - A Few Methodological Remarks, Lubomira Burchardt, Krzystof Lastowski, Harold G. Marshall

Biological Sciences Faculty Publications

Plant and animal populations are frequently found in habitats where the environmental conditions are considered extreme or challenging for life form to exist. These conditions may be classified as either: (1) Supreme: a situation characteristic of degradation conditions where only a few species live under stress, and (2) Extra-ordinary: habitats that provide high biodiversity that are under stress conditions. Due to the differences in what we consider extreme conditions, it is necessary to distinguish between these two categories, because they are not comparable. Our presentation will include examples of these two extreme environmental categories.

The Chick Embryo Amnion As An In Vitro Culture System For Ivf And Nt Embryos, Tonya Renea Davidson Jan 2004

The Chick Embryo Amnion As An In Vitro Culture System For Ivf And Nt Embryos, Tonya Renea Davidson

LSU Doctoral Dissertations

Calving rates are significantly reduced following in vitro production of embryos. Thus, if a technique could be developed that would increase calving rates by as little as one viable offspring, significant research advances could be made. Therefore, in a series of experiments, the efficiency and quality of culturing IVP bovine embryos in the amnion of a domestic chicken egg was tested. In Experiment I, by culturing IVP bovine embryos in the chick amnion (day 4 to 7 of incubation) it was discovered that there was no significant difference in blastocyst rates compared with controls. In Experiment II, it was shown …

Tuning Polymeric Chiral Surfactants For Enhanced Enantiomeric Recognition In Micellar Electrokinetic Chromatography, Jepkoech Tarus Jan 2004

Tuning Polymeric Chiral Surfactants For Enhanced Enantiomeric Recognition In Micellar Electrokinetic Chromatography, Jepkoech Tarus

LSU Doctoral Dissertations

The research presented in this dissertation involves the synthesis, modification, characterization, and the application of polymeric surfactants in micellar electrokinetic chromatography (MEKC). Sodium undecenoyl-L-Leucinate (L-SUL) was synthesized and modified by use of alkali metal counterions, alcohols, and Triton X-102. Characterization of the modified poly-L-SUL was performed in order to elucidate the structural changes on the surfactants by use of four techniques. While surface tensiometry was used for the determination of the critical micelle concentration (cmc), fluorescence measurements were used for the determination of the polarity of the modified polymeric surfactants. The information about the size of the polymeric surfactants was …

Molecular Systematics Of The Cashew Family (Anacardiaceae), Susan Katherine Pell Jan 2004

Molecular Systematics Of The Cashew Family (Anacardiaceae), Susan Katherine Pell

LSU Doctoral Dissertations

Anacardiaceae Lindl., the cashew family, is an economically important, primarily pantropically distributed family of 82 genera and over 700 species. This family is well known for its cultivated edible fruits and seeds (mangos, pistachios, and cashews), dermatitis causing taxa (e.g., Comocladia, Metopium, Semecarpus, Toxicodendron, etc.), and lacquer plants (Toxicodendron and Gluta spp.). The taxonomy of Anacardiaceae has not been thoroughly investigated since Engler established the currently used five tribal classification system over 100 years ago. This study evaluated evolutionary relationships of the family using nrDNA and cpDNA sequences. The first part of the study investigated the evolutionary position of Anacardiaceae …
