The Nature Of Semantic Memory Deficits In Alzheimer's Disease: Semantic Degradation Or Working Memory Deficits., Staci Robyn

Graduate Theses, Dissertations, and Problem Reports (ETD)

The nature of semantic memory deficits in Alzheimer's disease (AD) has been subject to controversy. It is unclear whether semantic memory is impaired because of degradation of semantic knowledge or due to information processing deficits. This study compared 18 patients with AD to 18 control participants who did not differ significantly in age, education, or gender on three working memory tasks. Three variations of the Self Ordered Pointing Task (SOPT) which varied in the degree of ability to utilize semantic processing skills were administered. Results indicated that patients with AD demonstrated working memory impairments compared to control participants. However, patients …

Immunotoxic Effects Of Pulmonary Exposure To Isobutyl Nitrite In The Murine Macrophage., Avijit Roy

Graduate Theses, Dissertations, and Problem Reports (ETD)

Isobutyl nitrite (IBN) is a volatile compound that causes vasodilation and smooth muscle relaxation. A history of abuse of this compound by HIV positive homosexual men has been associated with an increased incidence of Kaposi's Sarcoma, a tumor whose growth is responsive to cytokines. Previous work with the murine pulmonary model has demonstrated that exposure to IBN can suppress cytotoxic T cell ability, reduce the production of nitric oxide by macrophages and impair their ability to kill P815 targets. The overall aim of this project was to further characterize the nature of the immune alteration in the murine macrophages. In …

Searching For Evidence Of Transfer Between Drug Facilitators., Mark Aaron Miller

Graduate Theses, Dissertations, and Problem Reports (ETD)

Four experiments were conducted to test whether transfer of stimulus control could be obtained between two drug facilitators, a drug and non-drug facilitator, and two non-drug facilitators. In the first experiment, the presence of methadone signaled which of two key lights would be followed by grain. In the absence of methadone, the contingencies were reversed. Concurrently, the presence of phencyclidine (PCP) signaled which of two additional key lights would be followed by grain. In the absence PCP, the contingencies were also reversed. During transfer tests in which each conditioned stimulus (CS) was presented following administration of each drug facilitator, only …

Relationship Between Habitat And Ant Communities In Oak-Dominated Appalachian Forests Treated With Microbial Pesticides., Changlu Wang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ants in the George Washington (Augusta Co. VA, USA) and Monongahela National Forests (Pocahontas Co. WV, USA) were studied using pitfall traps and bait traps to assess the effect of Bacillus thuringiensis var kurstaki (Foray 48F) and gypsy moth nuclear polyhedrosis virus (Gypchek) application on ant communities and the association of habitat characteristics with ants. Ant samples were also compared by forest, sampling year and season, sampling method, and sampling micro-habitat. Pitfall traps were operated for 45 weeks during summers of 1995 to 1997. Bait traps were set up and collected 42 times during the same period. A total of …

Examination Of The Alpha(1)-Adrenoceptor Signal Transduction Cascade In Salt-Sensitive Hypertension., James M. Culhane

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of these studies were to identify the sites of changes in the {dollar}\\alpha\\sb1{dollar}-adrenoceptor signal transduction cascade responsible for a specific supersensitivity to norepinephrine (NE) that develops in the mesenteric arterial vascular bed from Dahl salt-sensitive rats (DS) maintained on a high salt diet (HS) for five days or three weeks as compared to Dahl salt-resistant rats (DR). Perfusion studies using the isolated perfused superior mesenteric arterial vascular bed from five day DSHS and DRHS rats and nifedipine, an L-type calcium channel blocker, were performed to assess tissue reliance on extracellular calcium for contraction. This study demonstrated that in …

The Relation Between Cardiovascular Reactivity To Stress And Family History Of Hypertension: Examination Of Overt And Covert Responses To Stressors., Nicole Lynn Frazer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Research has suggested that cardiovascular reactivity to stress may be a risk factor for the development of cardiovascular disorders (Manuck, 1994). Offspring of hypertensives have been hypothesized to be at greater risk for developing cardiovascular disorders through these exaggerated cardiovascular responses to stress, and therefore have been the focus of much research. Little empirical attention has been paid to the relation between other overt (e.g., verbal behavior) or covert (e.g., self-reported anger) responses exhibited during the laboratory session and family history status or cardiovascular reactivity to stress. The purpose of this investigation was to examine differences in overt and covert …

The Construction Of "The Student Perception Of Teacher Health Scale"., Steven Craig Koehn

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this study was to construct a student perception of a teacher's health scale. The rationale for the study was the severe lack of research on the effects of a teacher's health in the classroom environment. In addition, the tremendous dropout rate in the teaching profession due to burnout, stress and other health related factors was a key ingredient. Scale construction was deemed an important beginning component in investigation of an area with little prior investigation. The original scale was designed using student focus group participation. A sample of 54 undergraduate subjects were interviewed and audio-taped. Analysis of …

Ecology Of The Eastern Cottonmouth (Agkistrodon P. Piscivorus) At Back Bay National Wildlife Refuge: A Comparative Study Of Natural And Anthropogenic Marsh Habitats, Chad Lee Cross

Biological Sciences Theses & Dissertations

Mark-recapture sampling and radiotelemetry were used to investigate populations of the eastern cottonmouth, Agkistrodon p. piscivorus, in both natural and anthropogenic marsh habitats at Back Bay National Wildlife Refuge (BBNWR), Virginia Beach, Virginia from autumn 1995 to late spring 1998. Mark-recapture subjects were captured, marked by ventral scale-clipping, and released back into the population. A modified Schnabel Census estimator was used to estimate population sizes and corresponding densities in both marsh systems based on a total of 244 captures of 222 individuals. Most snakes were found >0.05 in from water, but it was apparent that proximity to water played …

A Hierarchical Filtering-Based Monitoring Architecture For Large-Scale Distributed Systems, Ehab Salem Al-Shaer

Computer Science Theses & Dissertations

On-line monitoring is essential for observing and improving the reliability and performance of large-scale distributed (LSD) systems. In an LSD environment, large numbers of events are generated by system components during their execution and interaction with external objects (e.g. users or processes). These events must be monitored to accurately determine the run-time behavior of an LSD system and to obtain status information that is required for debugging and steering applications. However, the manner in which events are generated in an LSD system is complex and represents a number of challenges for an on-line monitoring system. Correlated events axe generated concurrently …

Role Of The Warrant In Presidential Debates : 1960, 1976, & 1996, Aaron Nicole Kaio

Dissertations and Theses

Every four years in America we make a decision about which candidate is best suited to be our next president. Over the past twenty years a standard component of the presidential campaign has been televised debates. These debates are supposed to help the public get a better understanding of the candidates' ideas about government, our future, and to demonstrate analytical skills and their ability to think on their feet.

This study set out to see how the candidates' arguments measured up to some basic argumentation standards. According to several scholars, none of the televised presidential debates qualify as 'true debates', …

Cost Of Tsetse Trapping Using The Ng2g Trap: A Case Study In Kenya, George Tombe Lako

All Peer-Reviewed Publications

In a study to determine the costs of tsetse trapping in terms of construction materials, labour, transport and maintenance, two hundred forty-six traps used to control Glossina pallidipes in an area of 100 square kilometres at Nguruman, Kenya were evaluated from November 1990 to July 1992. The total cost of materials, labour and servicing per trap per year, was US$ 30.6 which, at that time was equivalent to 1071 Kenya shillings. ©1998ICIPE.

Effect Of Species, Age, And Sex Of Tsetse On Response To Infection By Metarhizium Anisopliae, Nguya K. Maniania, Adedapo Odulaja

All Peer-Reviewed Publications

Laboratory studies were carried out to determine the effect of sex and age on the susceptibility of tsetse, Glossina morsitans morsitans and G. m. centralis, to the entomopathogenic fungus, Metarhizium anisopliae. Both species of host flies were susceptible to fungal infection. Female flies were generally more susceptible than male flies. Three host ages (40, 20, and <1 day-old) were used; the youngest group was most resistant to fungal infection. Interactions between species, sex and age were significant on many occasions. Age usually accounted for the largest variability in mortality, followed by sex. All flies of age 40 days died between 7 and 8 days after infection whereas some of the younger flies, especially age 0, lived longer than 10 days. Log10 day probit (LDP) mortality regressions fitted well to most of the data sets. LDP slopes were significant and high, ranging between 4.3 and 12.8, indicating a generally high mortality rate of increase over days. The slopes differed significantly between species, sexes, and ages, but grouping by age was more intra homogeneous than by species or sex. The 50% lethal time mortalities (LT50) ranged between 4 and 7 days for age 0, 3 and 6 days for age 20, and about 5 days for age 40. Corresponding ranges of the LT95 were 8 to 20, 5 to 10, and 6 to 7 days for ages 0, 20 and 40, respectively. The significance of these results in the fungal disease transmission by tsetse is discussed.

Morphological Study Of Cultivated Cowpea Vigna Unguiculata (L.) Walp. Importance Of Ovule Number And Definition Of Cv Gr Melanophthalmus, Rémy Stéphane Pasquet

All Peer-Reviewed Publications

More than 400 cultivated cowpea accessions were studied using 29 morphophysiological characters. The analysis of data contrasts evolved cultivars and more primitive cultivars (and wild forms) according to seed size on the one hand and early and late flowering (under inductive conditions) on the other hand. The latter character is markedly correlated with ovule number. Photosensitive and early-flowering photoindependent cultivars have 11-17 ovules per pod and late flowering photoindependent cultivars have 16-25 ovules per pod. The analysis leads to assigning the accessions studied to the following different cultigroups: cv gr Unguiculata, cv gr Sesquipedalis, cv gr Biflora and cv gr …

Olfactory Responses Of Glossina Fuscipes Fuscipes (Diptera: Glossinidae) To The Monitor Lizard Varanus Niloticus Niloticus, M. M. Mohamed-Ahmed

All Peer-Reviewed Publications

Visual and olfactory responses of Glossina fuscipes fuscipes Newstead to the monitor lizard, Varanus niloticus niloticus Laurenti were studied using various catching devices near Lake Victoria, Kenya. Electric nets baited with visible lizards caught more males (x2.1) and significantly more females (x2.0) than unbaited nets. Lizards concealed in electrified black Pvc pipe models, simulating the shape and size of a monitor lizard, increased significantly the catches of tsetse by 2.1 times. Fresh lizard urine dispensed at an evaporation rate of 500 to 1000 mg/h also increased significantly the catches of flies at biconical traps, electrified models and electric nets. Identification …

The Effects Of A Dna Virus Infection On The Reproductive Otential Of Female Tsetse Flies, Glossina Morsitans Centralis And Glossina Morsitans Morsitans (Diptera: Glossinidae), Rosemary C. Sang, Walter G.Z.O. Jura, Leonard H. Otieno, Richard W. Mwangi

All Peer-Reviewed Publications

Reproductive anomalies associated with the tsetse DNA virus infection in the female tsetse hosts, Glossina morsitans centralis Machado and Glossina morsitans morsitans Westwood, inoculated with the virus during the 3rd instar larval stage were studied and the data compared to those obtained from the control females injected with sterile physiological saline. Virus infected flies had significantly longer first and second pregnancy cycles (P<0.0001) and produced pupae that were of significantly less weight in milligrams (P<-0.0001) compared to controls. Transmission of the virus to progeny was not absolute and only 21% of G. m. centralis and 48% of G. m. morsitans first progeny flies from infected females developed salivary gland hypertrophy as a result of transmission from mother to progeny. The virus infected females produced significantly fewere pupae compared to the controls during the experimental period (P<0.00001).

Energy Requirements For Certified Organic Farms In New Jersey : A Survey And Analysis Of Tomato Production, Cecilia Kelnhofer-Feeley

Theses

The focus of this thesis is to document the fossil fuel and electrical energy consumption required to grow certified organic tomatoes in the State of New Jersey. First, in order to evaluate the energy requirement for agriculture, a literature review of energy changes during the twentieth century is discussed. Secondly, an in-depth look at energy requirements for all farming types is evaluated. Third, previous studies of the energy requirements in agriculture are examined; this includes both analyzing organic and conventional farming practices. A survey was generated from the information gathered. The survey was conducted via face-to-face interviews. When all the …

The Magnitude Of Site And Time Interaction Effect In Tsetse Fly (Diptera: Glossinidae) Trap Catches, A. Odulaja, S. Mihok, I. M. Abu-Zinid

All Peer-Reviewed Publications

Site and time effects are important factors determining trap catches of tsetse flies. These factors may interact significantly and therefore confound interpretation of time series data used for population monitoring. We therefore investigated the magnitude and importance of site x time interactions in trap catches of Glossina pallidipes Austen and G. longipennis Corti using a 2200 trap-days (400 trap-months) data set. The interaction was found to be significant (P < 0.05) in 46-100% of the combinations of different numbers of months and sites between 2 and 12. The mean percent variance due to the interaction ranged between 4% and 28% for G. pallidipes and 12% and 36% for G. longipennis. The interaction was usually less important than the effect of site alone but more important than the effect of time alone. These results suggest that tsetse researchers should examine critically the adequacy of existing approaches to population monitoring with traps and to testing new traps and odour baits.
