This thesis explores the expectation gap and how it relates to the field of emergency management. As disasters become more commonplace, many citizens have high expectations of their governments, which results in a lack of individual disaster preparation. This thesis analyzed the current state of community education and engagement programs, use of best practices by governments and inter-agency cooperation and partnerships. The research consisted of fifteen interviews with emergency management professionals representing local, state, and federal government as well as the private sector. The results show limited public participation, as well as issues with crisis communications systems. Over 80% of research participants noted lack of disaster education programs as a serious issue. The results also show differences between expectation levels across demographic groups, limited educational program accessibility for minority populations and a difference in expectations between urban and rural residents.

As a theatre professional and a practicing Christian, I have found it very difficult to bring my two worlds together. Theatre is a tool for education, discussion, and understanding. In my work on this project, I have explored the ways in which theatre can and cannot help us understand each other on the volatile subjects that divide our contemporary culture: homosexuality and religion. Twenty-nine people with various backgrounds and worldviews were interviewed for this project. The words from these interviews were used to create the beginnings of a script for a play that explores the issues of homosexuality, religion, and the so-called "culture wars" from various points of view. While struggling to remain unbiased, this play also introduces new voices in theatre that are not commonly heard.

The purpose of this study is to determine whether or not having a laptop computer for individual use 24-hours-a-day, seven-days-a-week lessens differences between how eighth grade girls and eighth grade boys in 10 middle schools in HenricoCounty, Virginia perceive computer use and computer technology. Having a laptop computer to use at any time of the day or night eliminates the issue of competition between boys and girls for computer use. It also eliminates the need for either girls or boys to perform in front of other students while learning, thus lessening to some degree, feelings of computer anxiety. Competition for computer access and computer anxiety are two theories that have been offered to explain why many young women in previous studies have chosen not to use computers to the same extent that young men do, as well as why many young women generally do not consider computer-related careers as career options in their futures. A modified Computer Attitude Questionnaire, based upon the CAQ, Version 5.14 was used to survey eighth grade girls and boys in 10 Henrico County middle schools. Data collected from the surveys were analyzed using the statistical package, SPSS 14 for Windows. Comparisons were based on gender and on the self-reported race/ethnicity of the participants. A comparison of attitudes related to the number of computers already in the home in addition to the school-issued laptop was also conducted. A variety of statistical analyses were used in order to determine differences in attitudes between the boys and girls surveyed and the interactions between the attitudes of the respondents and their race/ethnicity. This was a non-experimental, quantitative, comparative research study.

The objective of this thesis is to frame the scope of application of the Vienna Convention on the International Sale of Goods and other instruments of private international law relating to the international sales contract. In this field the gaps in the Vienna Convention are analysed and methods to fill them are explored. The first chapter introduces the key terms of international trade law. First, the types of legal provisions are listed and then the sales contract is defined under both, the Czech law and the Vienna Convention. In the second chapter I focus on the overview of the development of international uniform sales law and on further sources of law, which are important for international transactions. Besides the Convention itself, I study the Rome I Regulation, the uniform principles of international contract law and the Common European Sales Law. The third chapter advances to the core of the thesis, the gaps in the Vienna Convention. After defining the gaps and characterising them, I formulate the basic principles underlying the Convention, which are to be used to fill the internal gaps. In the last, fourth chapter I selected three gaps in the Vienna Convention: interest rate, set off and the form of the contract. One by one, I explain their nature and all approaches to the gap-filling with...

Master of Science / Department of Electrical and Computer Engineering / William B. Kuhn / RF frequency synthesizer systems are prevalent in today’s electronics. In a synthesizer there is a sensitive analog oscillator that may be affected by two different types of noise. The first is random noise injection from active devices. This results in phase noise in the synthesizer’s spectrum. The second noise source is deterministic. A digital frequency divider with high-amplitude switching is an example of such a deterministic source. This noise enters the system through various forms of electric or magnetic field coupling and manifests itself as spurs or pulling. Both forms of noise can adversely affect system performance. We will first summarize methods for reducing noise. These already known steps have to do with layout techniques, device geometry, and general synthesizer topologies. Then we will show ways to isolate noisy interfering circuits from the sensitive analog systems. Finally, we present some considerations for reducing the effects of random noise. A power supply filter can improve the effects of deterministic noise such as undesired signals on the supply line. We show several ways to improve the rejection of high frequency supply noise (characterized by the power supply rejection ratio or PSRR) through the design of a voltage regulator. The emphasis is on new techniques for obtaining good PSRR at S-band frequencies and above. To validate the techniques, we designed a regulator in Peregrine Semiconductor’s .25µm ULTRA CMOS Silicon on Sapphire process. It produces a 2.5V output with an input ranging from 2.6V to 5V and has a maximum current sourcing of 70mA. The regulator’s low drop out performance is 60mV with no load and it achieves a power supply ripple reduction of 29.8 dB at 500 MHz. To address random noise in synthesizers, the thesis provides preliminary investigation of an oscillator topology change that has been proposed in the literature. This proposed change reduces the phase noise of the oscillator within the overall system. A differential cross-coupled design is the usual topology of choice, but it is not optimal for noise performance. We investigate current noise injection in the traditional design and present an updated design that uses a differential Colpitts oscillator as an alternative to classic cross-coupled designs.

Doctor of Philosophy / Department of Biochemistry and Molecular Biophysics / Thu Annelise Nguyen / Gap junctions (GJ) are intercellular channels connecting adjacent cells, allowing small molecules to transport between cells, thereby maintaining all homeostasis. Loss of gap junctional intercellular communication (GJIC) and/or connexins, the gap junction proteins, is a hallmark of cancer. Restoration of GJIC and/or increase of connexin expression have been related to the reduction of tumorigenesis. Connexins have been reported as tumor suppressors due to both GJIC-independent and -dependent mechanisms. Therefore, development of effective agents or methods to enhance GJIC and restore connexin expression in cancer cells is a new strategy in cancer treatment. PQ1, 6-Methoxy-8-[(3-aminopropyl)amino]-4-methyl-5-(3-trifluoromethyl-phenyloxy)quinoline, has been demonstrated to increase GJIC, restore connexin expression, and exert anti-cancer effects on T47D breast cancer cells. Studies of apoptotic pathways showed that PQ1 activated both extrinsic and intrinsic apoptotic pathways, indicating that PQ1 exerts its anti-cancer effects via a GJIC-independent mechanism through the induction of apoptosis. Combinational treatment of PQ1 and cisplatin showed that PQ1 counteracted cisplatin-induced inhibition of GJIC and reduction of connexin expression, thereby increasing the efficacy of cisplatin in T47D cancer cells via a GJIC-dependent mechanism. Further studies of drug distribution and toxicity revealed that administration of PQ1 by oral gavage can be achieved with low toxicity to normal vital organs. All the results suggest that PQ1, a gap junction enhancer, can function as an anti-cancer agent and potentiate the efficacy of antineoplastic drugs via both GJIC-independent and -dependent pathways.

Master of Science / Department of Agricultural Economics / Vincent R. Amanor-Boadu / Women represent approximately 50 percent of the active labor force in Sub-Saharan Africa. Even though women are involved in a variety of agricultural activities, they have limited access to resources and have restricted decision-making power compared to their male counterparts (FAO, 2011). These limitations and restrictions are likely to have a significant effect on women’s performance levels compared to men. The present research measures the gender-based performance differences, identifies factors that influence the financial performance levels, and factors contributing to generate disparities between male and female smallholders performance in northern Ghana. Data used in this study are from the Agriculture Production Survey (APS) focusing on the 2013-2014 cropping season. The study uses the Oaxaca-Blinder decomposition method to measure and decompose the gender performance gap in two parts: endowment effect and structural effect. Gross margin is used to measure farmer’s financial performance. The endowment effect is attributed to differences in the explanatory variables, and the structural effect is associated with differences in returns of the explanatory variables. Results from the study indicate there is a gender gap between male and female smallholder farmers with male farmers outperforming females by 46 percent. Land area had the largest significant impact on the explained part of the gender gap, followed by tractor service. The endowment effect portion of the decomposition models is accounted for 35 percent of the gender gap, and the remaining 65 percent is associated with the structural effect. The larger structural effect part suggests that developing programs to establish equality among male and female smallholder producers in terms of access to resources will not close the gender gap. Additionally, factors contributing positively overall to gross margin of smallholder farmers were land area, and tractor services and crops produced. Based on the results of this research, policymakers and agribusiness stakeholders may look to reduce the gender gap existing between smallholder farmers in northern Ghana by empowering women by providing them access to land area and tractor services. Further research into factors affecting the gender gap in financial performance in agricultural activities is warranted.

The submitted diploma thesis is dedicated to the calculation of the estimation of output gap by three estimating techniques (Hodrick-Prescott filter, Kalman filtering, and Cobb-Douglas production function) for the Czech Republic during the years 1995-2009, and, consequently, to their usefulness for testing the Okun's law as a suitable predicative tool. In other words, which of the mentioned methods is the most appropriate one for an accurate prediction of the rate of unemployment. To achieve this, the Box-Jenkins methodology is used for modelling and designing the cyclical unemployment forecasts and dynamic version of the Okun's law. The results indicate that, for the given period, there is relatively strong and unstable relationship between changes in output gap and changes in cyclical unemployment in the Czech Republic. The most suitable technique for the estimating of the future development of unemployment gap seems to be the Cobb-Douglas production function approach. This is namely based on the quantity of gained forecast errors and Granger causality.

This case study investigated the phenomenon of the black white test score gap by seeking to determine if there was a difference in the academic performance of African American students and their White peers. The determination of student academic performance was made using scores from second semester Algebra II classes at two high schools in the Tucson Unified School District. The data covered three academic years and was analyzed via SPSS (independent samples t-test, ANOVA, and a pairwise analysis) and content analysis for qualitative analysis. Findings revealed that there was no variance in the scores of African Americans and their White peers attending an affluent school; however African Americans attending a low-income school scored lower than all groups that were compared in this study.
