Robustness Of Some Estimators Of Linear Model With Autocorrelated Error Terms When Stochastic Regressors Are Normally Distributed, Kayode Ayinde, J. O. Olaomi

Journal of Modern Applied Statistical Methods

Performances of estimators of the linear model under different level of autocorrelation (ρ) are known to be affected by different specifications of regressors. The robustness of some methods of parameter estimation of linear model to autocorrelation are examined when stochastic regressors are normally distributed. Monte Carlo experiments were conducted at both low and high replications. Comparison and preference of estimator(s) are based on their performances via bias, absolute bias, variance and more importantly the mean squared error of the estimated parameters of the model. Results show that the performances of the estimators improve with increased replication. In estimating …

Diviva Is Required For Polar Growth In The Mreb-Lacking Rod-Shaped Actinomycete Corynebacterium Glutamicum, Michal Letek, Efrén Ordóñez, José Vaquera, William Margolin, Klas Flärdh, Luis M Mateos, José A Gil

Faculty, Staff and Student Publications

The actinomycete Corynebacterium glutamicum grows as rod-shaped cells by zonal peptidoglycan synthesis at the cell poles. In this bacterium, experimental depletion of the polar DivIVA protein (DivIVA(Cg)) resulted in the inhibition of polar growth; consequently, these cells exhibited a coccoid morphology. This result demonstrated that DivIVA is required for cell elongation and the acquisition of a rod shape. DivIVA from Streptomyces or Mycobacterium localized to the cell poles of DivIVA(Cg)-depleted C. glutamicum and restored polar peptidoglycan synthesis, in contrast to DivIVA proteins from Bacillus subtilis or Streptococcus pneumoniae, which localized at the septum of C. glutamicum. This confirmed that DivIVAs …

Two Concepts Of Irreversible Environmental Harm, Cass R. Sunstein

Public Law and Legal Theory Working Papers

The concept of “irreversibility” plays a large role in the theory and practice of environmental protection. Indeed, the concept is explicit in some statements of the Precautionary Principle. But the idea of irreversibility remains poorly defined. Because time is linear, any loss is, in a sense, irreversible. On one approach, drawn from environmental economics, irreversibility might be understood as a reference to the value associated with taking precautionary steps that maintain flexibility for an uncertain future (“option value”). On another approach, drawn from environmental ethics, irreversibility might be understood to refer to the qualitatively distinctive nature of certain environmental harms—a …

A Review On The Potential Uses Of Ferns, M. Mannar Mannan, Muthia Maridass, B. Victor

Ethnobotanical Leaflets

Man has been using plants as a source of food, medicines and many other necessities of life since ancient times. Even to this day the primitive tribal societies that exist depend on the plant life in their surroundings. Though there were investigations of the edible economic values of the higher plants, especially the pteridophytes and angiosperms have been unfortunately ignored. The pteridophytes are used in Homoeopathic, Ayurvedic, Tribal and Unani medicines and provides food, insecticides and ornamentations.

Will Herbal-Paracetamol Combination Drug Prevent Both Liver And Kidney Disease? - Results And Possibilities, Anjali Sharma, Mukesh Makwana, H. S. Rathore

Ethnobotanical Leaflets

An attempt has been made to briefly review the existing information on herbal compounds which could combat acetaminophen (paracetamol) toxicity. A careful perusal of literature revealed that acetaminophen overdose not only damages liver but also the kidney. Nevertheless, the kidney was badly ignored in studies aimed at preventing paracetamol toxicity with herbal drugs. On account of such major neglect, so far no herbal-paracetamol combination could be made. Milk thistly is only well researched drug which appears as a suitable future candidate, but its action towards the kidney must be studied. The importance of such studies in the future is discussed.

Records Of Natural Fires And The Sorption Of Polycyclic Aromatic Hydrocarbons (Pahs) By Black Carbon And Carbon Chars In Sediments From Oriole Lake (Sequoia National Park), Kevyn Bollinger

Senior Honors Projects

This project investigates the interaction between Black Carbon and Polycyclic Aromatic Hydrocarbons (PAHs) in lake sediments from Oriole Lake in Sequoia National Park California. The interaction between Black Carbon and PAHs is of interest because little is known with respect to the availability and the time scale within which black carbon adsorbs PAHs in a natural system. Black Carbon and PAHs both will eventually be degraded in the environment but the relevant timescales of sorption and degradation are unknown. Field work for this project was conducted July 16-21, 2007 at Oriole Lake in Sequoia National Park California. Sequoia National Park …

Gender Minority Elder Care, Yisrael Malotte-Berger

Senior Honors Projects

The challenges facing older adults are great, including the challenges involved in finding quality healthcare and, potentially, assisted living or nursing residences. The challenges for older transsexual, transgender, and intersex (TGI) adults are compounded due to lack of sensitivity and confidentiality with regard to TGI patients or residents that is prevalent amongst especially lower level healthcare professionals. Part of the project was to develop an evaluation tool for changes in attitude and practical knowledge, to be administered as pre- and post-tests at employee trainings at elder care facilities. It was the goal of this project to evaluate the training programme …

The Effects Of Attributional Style On Learning : Engagement As A Mediator, Courtney A. Hopkins

Theses, Dissertations and Culminating Projects

This study investigated the effects of attributional style on learning outcomes, with engagement in learning as a mediator. A model was developed to depict this relationship, suggesting that attributional style affects learning both directly and indirectly, with academic and civic engagement as a mediator between attributional style and learning. Hypothesis 1 stated that attributional style is related to academic performance, such that students with a positive attributional style will exhibit higher academic performance than students with a negative attributional style. Hypothesis 2 stated that engagement mediates the relationship between attributional style and academic performance. The data used in this study …

Optimization Of Expression And Purification Of Acetoacetyl-Coa Thiolase From Sunflower, Anthony Muriithi Maina

Theses, Dissertations and Culminating Projects

The [beta]-oxidation system in sunflower (Helianthus annuus L.) cotyledons is distinguished by the existence of two different thiolase isoforms, Thiolase I (acetoacetyl-CoA thiolase, EC 2.3.1.9 AACT) and Thiolase II (3-oxoacyl-CoA thiolase, EC 2.3.1.16 OACT). Glyoxysomal AACT is the last enzyme in the p-oxidation of fatty acids in plant glyoxysomes. Glyoxysomal AACT has been successfully cloned, expressed and purified from sunflower cotyledons (Dyer et al., 2006). In this paper we investigate the optimal conditions for both expression and purification. These include the choice of vector, the growth conditions and the purification parameters for the maximum possible yield of AACT protein.

Evelyn Waugh's Deceptions Of The "Decline And Fall" Of "Vile Bodies" Into "A Handful Of Dust", Allison Elaine Nazimek

Theses, Dissertations and Culminating Projects

In the years in between the two World Wars, Britain witnessed many changes in the behavior and ethics of the emerging younger population. There were positive advances, especially in the education of truant students and the development of experimental schools, such as Neill’s Summerhill (Graves 209-11). There was also an emergence in public smoking, drinking, and heightened hemlines symbolizing modern times and a freer youth (Graves). These changes exhibited a shift from more rigid, Victorian ideals, yet, the real problems remained in the excess activities in which a wilder crowd indulged. Alcohol abuse became a concern, as the Practitioner stated …

The Analysis Of The Natural Attenuation Of Chlorinated Solvents In Groundwater At The Former Westinghouse Site In Bloomfield, New Jersey, Deborah J. Katchen

Theses, Dissertations and Culminating Projects

Data for a contaminated site in Bloomfield, New Jersey were gathered from the New Jersey Department of Environmental Protection (NJDEP), in order to evaluate the hydrogeological conditions at the site. In particular, the data were analyzed to determine whether: 1) the site is still significantly contaminated, 2) natural attenuation is occurring at the site, and 3) natural attenuation will completely remediate the site in a reasonable period of time. The occurrence and distribution of Trichloroethene (TCE) and its daughter products, Dichloroethene (cis 1,2 DCE) and Vinyl Chloride (VC) show that the site is still contaminated.

It was observed that the …

Toward An Anarchist Theory Of Self: Wilderness, Actualization And Authority, Joseph Amos Garcia

College of Graduate Studies: Theses & Dissertations

This research investigated essential components of optimal human functioning. An anarchist model was used to emphasize the autonomous nature of an optimally functioning self. Utilizing Abraham Maslows hierarchy of needs model, Leonard Martins ID compensation theory, fundamental principles of anarchist theory and environmental feedback paradigms it has been shown that time spent during backpacking experiences in the wilderness may simulate immediate return social systems, allow for recognition of need fulfillment and ultimately increase self-actualization. In addition it was shown that materialism, via an ownership index, is negatively correlated with actualization. Utilizing a backward regression analysis the resulting model supports the …

Foraging Ecology Of Seabirds In Relation To Commercial Shrimp Trawler Activity, Lisa Wickliffe

All Theses

Population dynamics of seabirds have been linked to the availability of bycatch discarded from commercial fishery operations. This issue has been examined primarily in Europe where studies demonstrated that tens of thousands of seabirds each year may be supported by discards from a regional fishery, and that discards from commercial fisheries contributed to the increase in seabird abundance and to changes in their distribution in the North Sea and Northeast Atlantic. To date, however, little to no research has been conducted on seabird-fisheries interactions in the United States. This research examined this issue in the coastal waters of South Carolina …

The Effects Of Land Use On Sedimentation, Inorganic Substrate, Organic Substrate, And Fish Assemblages In South Carolina's Coastal Plain Streams, Cathy Marion

All Theses

This research is part of a larger, long-term assessment of South Carolina's wadeable streams funded by the South Carolina Department of Natural Resources entitled the 'South Carolina Stream Assessment Project'. Biological, physical, and chemical data were collected for this project during the summer seasons of 2006 and 2007. The purpose of this research was to identify relationships among land use, sedimentation, organic substrate, and fish assemblages in three South Carolina coastal plain ecobasins. An additional focus was to determine if South Carolina coastal plain ecobasins were similar enough in species composition, environmental variables, land use, and measured fish metrics to …

2008 Epa’S Report On The Environment

United States Environmental Protection Agency: Publications

To accomplish its mission, the U.S. Environmental Protection Agency (EPA) must pay close attention to trends in the condition of the nation’s air, water, and land, and to associated trends in human exposure and health and the condition of ecological systems. Data on environmental trends serve two key purposes: they provide valuable input to EPA in developing its strategic outlook and priorities, and they allow EPA and the public to assess whether the Agency is succeeding in its overall mission to protect human health and the environment. EPA prepared this Report on the Environment (ROE) to accomplish these purposes.

Elk Calf Survival And Mortality Following Wolf Restoration To Yellowstone National Park, Shannon M. Barber-Meyer, L. David Mech, P. J. White

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

We conducted a 3-year study (May 2003–Apr 2006) of mortality of northern Yellowstone elk (Cervus elaphus) calves to determine the cause for the recruitment decline (i.e., 33 calves to 13 calves/100 adult F) following the restoration of wolves (Canis lupus). We captured, fit with radiotransmitters, and evaluated blood characteristics and disease antibody seroprevalence in 151 calves ≤6 days old (68M:83F). Concentrations (x, SE) of potential condition indicators were as follows: thyroxine (T4; 13.8 μg/dL, 0.43), serum urea nitrogen (SUN; 17.4 mg/dL, 0.57), γ-glutamyltransferase (GGT; 66.4 IU/L, 4.36), gamma globulins (GG; 1.5 g/dL, 0.07), and insulin-like growth …

Investigating The Affects Of Cucurbitacin-I On Cellular Motility, Rebecca Lafleur

Honors Scholar Theses

Cellular migration is an integral component of many biological processes including immune function, wound healing and cancer cell metastasis. A complete model illustrating the mechanism by which cells accomplish movement is still lacking. Exploring the affects of various drugs on cell motility may be instrumental in discovering new proteins which mediate cell movement. This project aims ultimately to characterize the molecular target of the drug Cucurbitacin-I, a natural plant product. This drug has been shown to inhibit migration of epithelial sheets and may have anti-tumor activity.

In this paper, we show that Cucurbitacin-I inhibits the migration of MDCK and B16F1 …

Ontogenetic Effects Of Hatching Plasticity In The Spotted Salamander (Ambystoma Maculatum) Due To Egg And Larval Predators, Leah Brown-Wilusz

Honors Scholar Theses

The ability to respond plastically to the environment has allowed amphibians to evolve a response to spatial and temporal variation in predation threat (Benard 2004). Embroys exposed to egg predation are expected to hatch out earlier than their conspecifics. Larval predation can induce a suite of phenotypic changes including growing a larger tail area. When presented with cues from both egg and larval predators, embryos are expected to respond to the egg predator by hatching out earlier because the egg predator presents an immediate threat. However, hatching early may be costly in the larval environment in terms of development, morphology, …

In Vitro Exploration Of Macrophage Migration Inhibitory Factor (Mif) As A Possible Agent Of Lymphatic Dilation In The Pathogenesis Of Lymphatic Filiariasis, Lauren Rosen

Honors Scholar Theses

Abstract:Macrophage Migration Inhibitory Factor (MIF) is a human cytokine that is well known for its role in modulating macrophage function. It has also been shown to cause smooth muscle cell death. A homolog of the MIF protein (BmMIF) has been found in Brugia malayi, one of the etiological agents of lymphatic filariasis. BmMIF shares a significant portion of its sequence homology with human MIF. Infection by Brugia malayi leads to a consistent finding of lymphatic dilation with surrounding smooth muscle cell apoptosis. We hypothesize that Brugia malayi releases BmMIF as a mediator of host smooth muscle cell death in the …

The Effects Of Physical And Chemical Modulating Agents On The Induction Of Vaccine-Induced Immune Responses, Andrea Nicole Ryan

Honors Scholar Theses

After the development of the viral-based prostate cancer vaccine, Ad5-PSA, much research has been orientated to help enhance the induced immune response by combining the vaccine with physical and chemical modulating agents, more specifically the polymers polyethylenimine (PEI), chitosan, and chitosan coated with CD3 complex antibodies; all previously shown to stimulate an immune response as isolated gene carriers. To compare the vaccine-induced immune responses between the naked vaccine and the polymer-vaccine combinations, a mouse model using the ovalbumin- specific Ad-OVA vaccine was tested using intracellular cytokine staining (ICS), tetramer staining, and cytotoxic T-cell lymphocyte assays to measure the activation of …

Meanings Of Weighing Female Patients And Their Clinical Implications, Zenobia C. Y. Chan

Journal of International Women's Studies

Severe weight loss is the chief characteristic of anorexia nervosa. Weight is also one of the important indicators for evaluating a client’s recovery. I weighed all clients at their pre-treatment interview, the beginning of every family session, and at the termination session, and kept records based on follow-up telephone calls after family treatment ended. I found the process of weighing to be noteworthy not only as an instrumental task, but also as a reciprocal learning experience between the clients and myself. Also, my role as the “weigher” of the clients had unexpected effects on my peers, my family and myself. …
