Glaciotectonic Deformation Along The Valparaiso Upland In Southwest Michigan, Usa, Brian C. Bird

Dissertations

Glaciotectonic deformation has been observed and analyzed across parts of the Valparaiso, Kendall, and Inner Kalamazoo Moraines in southwest Michigan, USA. Deformation structures such as folds and faults have been analyzed using techniques typically used by structural geologist along with the fabric of elongated clasts in the surficial diamicton. The structures are consistent with simple shear, horizontal compressional stresses, and pure shear. A series of drumlin fields exist along the western boundary of the study area. Direct investigation of the deformed sediments was conducted at a gravel pit in one of these drumlins. Lacustrine derived sediments interbedded with coarse sand …

Essential Personal Attributes, Skills And Abilities Needed By Aspiring Community College Presidents, Jeffery Steven Boyd

Dissertations

The community college presidency is in critical state of evolution. Boggs (2003) stated that the rate of presidential retirements appears to be on the rise, with 79% of presidents planning to retire by 2012. Weisman and Vaughn (2007) in a 2006 survey found the number of presidents planning to retire within ten years is 84%. The most likely candidates to fill these presidential vacancies are the senior administrators. This presents a challenge because the senior administrators are at the same age as the retiring presidents and they too are preparing for retirement.

The previous generations of community college presidents, the …

Community College Succession Planning: Preparing The Next Generation Of Women For Leadership Roles, Angela Kaysen Luzbetak

Dissertations

The purpose of this study was to explore strategies to enable community colleges to develop and cultivate women for leadership roles through succession planning. According to the American Association of Community Colleges (AACC), the pace of administrative and other key staff retirements exceeds the pace at which these positions are being re-staffed (Shults, 2001). One might question why the purposeful development of future community college leaders is critical. Community colleges currently face a crucial leadership crisis in the United States. Pending retirements and the lack of succession planning to fill upcoming vacancies is reaching a critical turning point. The Chronicle …

Hardware Support For Real-Time Network Security And Packet Classification Using Field Programmable Gate Arrays, Nitesh Bhicu Guinde

Dissertations

Deep packet inspection and packet classification are the most computationally expensive operations in a Network Intrusion Detection (NID) system. Deep packet inspection involves content matching where the payload of the incoming packets is matched against a set of signatures in the database. Packet classification involves inspection of the packet header fields and is basically a multi-dimensional matching problem. Any matching in software is very slow in comparison to current network speeds. Also, both of these problems need a solution which is scalable and can work at high speeds. Due to the high complexity of these matching problems, only Field-Programmable Gate …

Properties And Device Applications Of Silicon And Silicon-Germanium Nanostructures With Different Dimensions, Han-Yun Chang

Dissertations

Defect-free crystalline Si/SiGe(Ge) nanostructures are demonstrated despite the 4% lattice mismatch between Si and Ge. The lattice mismatch-induced strain is sufficiently relaxed through the designed, cluster morphology, or nanowire (NW) structures. Future device applications of these nano structures require complete understanding of their structural, optical, electrical and thermal properties. This study explores these properties in two-dimensional (2D) Si/Si:B delta-doped multilayers, 2D Si/Si_1-xGe_x planar multilayers, three-dimensional (3D) Si/Si_1-xGe_{x cluster multilayers, one-dimensional (1D) Si NWs and 1D Si/Ge NW heterojunctions (HJs).}

The Floating Contract Between Risk-Averse Supply Chain Partners In A Volatile Commodity Price Environment, Mojisola Kike Otegbeye

Dissertations

In this dissertation, two separate but closely related decision making problems in environments of volatile commodity prices are addressed. In the first problem, a risk-averse commodity user's purchasing policy and his risk-neutral supplier's pricing decision, where the user can purchase his needs through contract with his supplier as well as directly from the spot market, are analyzed. The commodity user is assumed to be the supplier's sole client, and the supplier can always expand capacity, at a cost to the user, to accommodate the user's demand in excess of initially reserved capacity.

In the more generalized second problem, both parties …

Constitutive Modeling Of Glassy Memory Polymers, Mahesh Khanolkar

Dissertations

The aim of this research is to develop constitutive models for non-linear materials. Here, issues related for developing constitutive model for glassy shape memory polymers are addressed in detail. Shape memory polymers are novel material that can be easily formed into complex shapes, retaining memory of their original shape even after undergoing large deformations. The temporary shape is stable and return to the original shape is triggered by a suitable mechanism such heating the polymer above a transition temperature. Glassy shape memory polymers are called glassy because the temporary shape is fixed by the formation of a glassy solid, while …

Transport Mechanisms And Modeling Of Riser Reactor, Dawei Wang

Dissertations

Riser reactors are extensively employed in various industrial applications. In a riser reactor, the hydrodynamics is closely interacted with kinetic reactions. Common models for the performance prediction of riser reactors overlook this vital coupling effect, which not only miss the important reaction characteristics in the dense-phase transport regime of riser reactors but also misinterpret the kinetic properties via ad hoc adjustments. It is noted that the modeling of hydrodynamics in riser flows has major flaws in its predictability of phase transport in both dense-phase and accelerating regimes where most reactions occur. In addition, with the spray feeding of reactants at …

Optimizing Integrated Service For A Transit Route With Heterogeneous Demand, Yavuz Yusuf Ulusoy

Dissertations

The methodology developed in this dissertation attempts to optimize integrated service that minimizes the total cost, including user and supplier costs, of a transit route with heterogeneous demand. While minimizing total cost, a set of practical constraints, such as capacity, operable fleet size and frequency conservation, are considered.

The research problem is presented in three scenarios, consisting of various service patterns (e.g., all-stop, short-turn and express) under heterogeneous demand. A logit-based model was used to estimate passenger transfer demand. An exhaustive search method was developed to find the optimal solutions for a simplified transit route with six stops, and a …

This dissertation addresses this lack of knowledge by looking at the effects of current noxious odor on residents' lives in three residential communities in northern New Jersey: West Caldwell, Newark's North Ward and Garfield- Lafayette in Jersey City. The research examines the coping process residents adopt to deal with this environmental annoyance.

In this study I explore two ways residents cope with odor: reactively (trying to keep the odor out of their homes) …

Experiences Of Pregnancy, Childbirth And Post-Partem Period In Urban And Suburban Immigrant Pakistani Women, Rubab I. Qureshi

Dissertations

A body of research suggests that immigrants arrive in the U.S. in good health, a healthy immigrant effect. As immigrants acculturate and absorb dominant cultural norms (measured by proxy variables such as language preference, employment, smoking and alcohol consumption), their health status deteriorates. There is a need to understand how immigrants adapt to a changed social and cultural environment and how this may influence health.

A study of pregnancy, childbirth and the postpartum period in immigrant Pakistani women living in New Jersey explored the interface of culture, immigration and health. The study employed a three pronged approach. Census data were …

Variance Reduction Techniques For Estimating Quantiles And Value-At-Risk, Fang Chu

Dissertations

Quantiles, as a performance measure, arise in many practical contexts. In finance, quantiles are called values-at-risk (VARs), and they are widely used in the financial industry to measure portfolio risk. When the cumulative distribution function is unknown, the quantile can not be computed exactly and must be estimated. In addition to computing a point estimate for the quantile, it is important to also provide a confidence interval for the quantile as a way of indicating the error in the estimate. A problem with crude Monte Carlo is that the resulting confidence interval may be large, which is often the case …

Mechanisms For Quality-Of-Service Provisioning In Networks With Extended Services, Zhen Qin

Dissertations

The emerging network traffic with various Quality-of-Service (QoS) requirements creates a demand for QoS service provisioning beyond the best effort service that Internet currently provides. QoS provisioning requires a framework that satisfies users' QoS and cost demand while maximizes benefits for network service providers. It is considered that QoS provisioning involves three issues: a) estimations of the network QoS performance, which can be achieved by performing network measurement; b) dissemination of the measured QoS states throughout the network with states exchanged among different network routers; and c) QoS routing. In this dissertation, these three issues are addressed.

In QoS networks, …

The Commission decided in “examining a measure to assist the restructuring of a firm in difficulty, its overall assessment (was) to consider whether the common interest is served by the maintenance of the firm in business, …

California Charter School Closures: Perspectives And Advice From Nine Former Charter School Directors, Jennifer Reiter-Cook Edd

Dissertations

Charter schools have been categorized as "everyone's reform" (Bracey, 2004); they are a type of public school, first established in 1992, that normally has fewer restrictions than most public schools and that serves a student body that, in many circumstances, has consciously opted to attend the school. Charter schools have promised high student achievement and program options that would create healthy competition in the American educational market. Currently, in California alone, there are approximately 800 active charter schools that serve more than 340,000 pupils. As we close in on nearly twenty years of charter school reform, many charter schools could …

Individuals Differences In Exploratory Behavior Of Prairie Voles, Microtus Ochrogaster, Danielle N. Lee

Dissertations

Individual differences in behavior are significant because they serve as the substrate for natural selection. Within the Behavioral Syndromes framework, researchers study individual differences in behavior of animals. Behavioral Syndromes are defined as correlations between behaviors in different environmental contexts or testing situations. In this study, I examined the effects of litter size and sex ratio, familial relationships, and age and sex on exploratory behavior of prairie voles, Microtus ochrogaster. Exploratory behavior, defined as spontaneous behavioral responses to unfamiliar stimuli, was examined in three novel situations: an open-field with novel objects, a two-way novel choice apparatus, and a complex maze. …

Hellfire And Academic Dishonesty: An Empirical Evaluation Of The Influence Of Religious Orientation On Academic Deviance, Jason Robert Jolicoeur

This issue has taken on increased importance in an era in which higher education that has been characterized by calls for increased institutional accountability. While past studies have shed light on the issue of academic dishonesty, there are still a number of critical variables pertaining to student cheating that have yet to be examined. This exploratory study examined whether religious orientation influences three variables related to academic dishonesty; student perceptions of the prevalence of academic dishonesty, general student attitudes toward …

An "Uneasy Look At Performance Appraisal": Beliefs About Performance Appraisal Outcomes, Cognitive Appraisals, And Emotions As Antecedents Of Upward Rating Distortion, Shirley Ann Ashauer

Dissertations

The face-to-face feedback element of performance appraisal has been described as the “Achilles’ heel” of the entire process. Specifically, the upward distortion of ratings made for feedback purposes is believed to be a pervasive effect. Two studies were conducted to explore factors to help understand the upward distortion of ratings that must be fed back – the first using a survey design from actual work settings and the second conducted as a laboratory experiment. Findings in the first study revealed that, regardless of feedback valence, upward rating distortion was minimized as positive emotions and supervisor beliefs of beneficial outcomes increased, …

A Qualitative Study Of A Native American Mascot At "Public University", Michelle Lyn Brune

Dissertations

At the time this study began, there were approximately 60 senior colleges and universities using Native American mascots or nicknames to represent their athletic teams (Fournier, 2003). Many Native Americans, coalitions, organizations, and researchers (Connolly, 2000; Davis, 2002; King & Springwood, 2000; NCAA, 2001) believe that these mascots are racist stereotypes of Native Americans and recommend that they be banned. In contrast, other people believe that Native American mascots signify honor and tradition. Differing meanings or opinions create an obvious conflict and each viewpoint includes a set of arguments to justify their beliefs. For example, many universities claim their alumni …

Effect Of Anions On The Iron Release Pathways Of Human Serum Transferrin, Rashmi Subhash Chander Sharma

Dissertations

Transferrin, the serum iron transport protein in humans, is used to transport 30-40 mg of iron per day through blood. The accessibility of transferrin makes it an attractive target for iron cheating therapeutic agents used in the treatment of iron overload. There is an ongoing search for ligands which can accelerate the rate of iron release, as the currently approved drug DFO has a very slow rate for iron removal. Previous studies have shown that anions can accelerate the rate of iron release. Studies on the effect of anions on the rates of iron release from C-terminal monoferric transferrin at …
