The Asymmetric Explosion Of Type Ia Supernovae As Seen From Near-Infrared Observations, Kentaro Motohara, Keiichi Maeda, Christopher L. Gerardy, Ken'ichi Nomoto, Masaomi Tanaka, Nozomu Tominaga, Takuya Ohkubo, Paolo A. Mazzali, Robert A. Fesen, Peter Hoflich, J. Craig Wheeler

Dartmouth Scholarship

We present near-infrared spectra of late-phase (>200 days) Type Ia supernovae (SNe Ia) taken at the Subaru Telescope. The [Fe II] line of SN 2003hv shows a clear flat-topped feature, while that of SN 2005W shows a less prominent flatness. In addition, a large shift in their line center, varying from -3000 to 1000 km s^-1 with respect to the host galaxies, is seen. Such a shift suggests the occurrence of an off-center, nonspherical explosion in the central region and provides important, new constraints on the explosion models of SNe Ia.

Spitzer Measurements Of Atomic And Molecular Abundances In The Type Iip Sn 2005af, Rubina Kotak, Peter Meikle, Monica Pozzo, Schuyler D. Van Dyk, Duncan Farrah, Robert Fesen, Alexei V. Filippenko, Ryan J. Foley, Claes Fransson, Christopher L. Gerardy, Peter A. Hoflich, Peter Lundqvist, Seppo Mattila, Jesper Sollerman, J. Craig Wheeler

Dartmouth Scholarship

We present results based on mid-infrared (3.6-30 μm) observations with the Spitzer Space Telescope of the nearby Type IIP supernova 2005af. We report the first ever detection of the SiO molecule in a Type IIP supernova. Together with the detection of the CO fundamental, this is an exciting finding as it may signal the onset of dust condensation in the ejecta. From a wealth of fine-structure lines we provide abundance estimates for stable Ni, Ar, and Ne that, via spectral synthesis, may be used to constrain nucleosynthesis models.

Merck Kgaa V. Integra Lifesciences I, Ltd.: Greater Research Protection For Drug Manufacturers, Samuel Rubin

Duke Journal of Constitutional Law & Public Policy Sidebar

Merck sought protection under a statutory exemption from claims of patent infringement brought by Integra Lifesciences. The Court held unanimously that the safe harbor contained in 35 U.S.C. § 271(e)(1) protected the use of patented inventions used in preclinical research where the results were not submitted to the FDA. The Court's interpretation of the safe harbor provision broadened protection for those engaged in drug research at a substantial cost to patent-holders.

Duan's Fixed Point Theorem: Proof And Generalization, Martin Arkowitz

Dartmouth Scholarship

Let X be an H-space of the homotopy type of a connected, finite CW-complex, f : X→X any map and p_k : X→X the k^th power map. Duan proved that p_kf : X → X has a fixed point if k ≥ 2. We give a new, short and elementary proof of this. We then use rational homotopy to generalize to spaces X whose rational cohomology is the tensor product of an exterior algebra on odd dimensional generators with the tensor product of truncated polynomial algebras on even dimensional generators. The role of the power map …

Media, Race, And Attitudes Toward People On Welfare, Stephanie Bramlett

Master's Theses and Capstones

This research gives insight to why some Americans have negative attitudes toward people on welfare. This study begins by exploring how the construct of race has manifested itself throughout televised news broadcasts and the welfare system in the United States.

This research uses a combination of content analysis, secondary research and American National Election Survey Data analysis to explain the relationship between the media and support for welfare programs. The study investigates three main hypotheses: H1: Blacks are overrepresented as perpetrators of crime in televised news broadcasts compared to the actual number of crimes committed by Blacks, H2: As trust …

Incidence Of Ticket Taxes And Fees In United States Domestic Air Travel, Joakim Karlsson

Master's Theses and Capstones

The United States is currently witnessing a vigorous debate on public funding of air transportation and the role of taxes and fees levied on airline tickets. Yet, there is remarkably little economic literature on taxation in the U.S. airline industry. Analysis of a large sample of tickets for travel in the continental United States shows that the effective tax rate has increased from 11% in 1993 to 16% in 2005. While the tax structure and levels have changed over time, this increase is largely due to a historical decline.

The theory of tax incidence asserts that economic incidence is a …

The Economics Of Childbearing: Three Essays, Andrea Kutinova

Doctoral Dissertations

Expenditure programs, business cycles, and government interventions can affect many decisions surrounding the birth of a child. For example, public insurance programs such as Medicaid have the potential to increase the utilization of prenatal care. This, in turn, may lead to better infant and maternal health outcomes. Given the high and increasing number of pregnant women covered by Medicaid, the effectiveness of the program in promoting prenatal care use and improving health needs to be evaluated. Also, the impacts of business cycles on childbearing are of interest to policymakers. For example, does unemployment substantially affect the decision to conceive a …

Non-Linear Aspects Of Financial Integration: An Analysis Of The Real Interest Rate Parity For Southeast Asian Economies, Fabricio Linhares

Doctoral Dissertations

This study assesses the extent to which selected economies in Southeast Asia are financially integrated among themselves and internationally, and investigates whether financial integration in the region increased following the deregulation of their markets over the 1980's and early 1990's. The analysis is carried out by examining the relationship between ex post real interest rates over 1970-2005. Following the work of Meese and Rogoff (1988), countries are considered financially integrated based on the stationarity property of their real interest rate differentials. Conclusions are drawn from a confirmatory analysis, which contrasts results from unit root tests, with and without structural breaks, …

Characterization Of Single-Sided Cadmium Zinc Telluride Strip Detectors For High Energy Astrophysics Applications, Burcin Donmez

Doctoral Dissertations

Cadmium zinc telluride (CdZnTe or CZT) was introduced as a new room temperature semiconductor detector due to its good energy resolution, high atomic number, high density and good stopping power in the early 1990s. UNH has focused on developing CZT strip detector designs for astrophysical measurement applications in the 0.05 to 1 MeV photon energy range. This thesis presents characterization efforts of two types of single-sided CZT strip detector: non-charge sharing orthogonal coplanar strip detectors and charge-sharing strip detectors. The characterization includes spectroscopy, imaging, uniformity and efficiency measurements. Measured energy resolutions with both detector designs are better than those obtainable …

Family Structure, The State Children's Health Insurance Program (Schip) And Child Outcomes, Minghua Li

Doctoral Dissertations

This dissertation consists of three separate but interrelated essays that investigate how family structure and public policy are linked to health and developmental child outcomes. Each essay employs two or three waves of the National Survey of America's Families (NSAF) as the primary data source. The first essay broadly investigates how family structure, including the less typical non-traditional families such as single father and grandparent households, are related to a wide of array of child outcomes with a focus on the interplay of parent-child gender. The results from this study show that children in single father families have better health …

An Analysis Of Social Skills Instruction Provided In Teacher Education And In-Service Training Programs For General And Special Educators, Nicole Dobbins

UNLV Retrospective Theses & Dissertations

The effective demonstration of social skills in classroom and personal settings is essential to successfully develop and sustain professional and personal relationships. Students with disabilities often exhibit social skills deficits which, in turn, place them at risk to experience school failure, peer rejection, and/or mental health problems (Elksnin & Elksnin, 2006). There is an increasing number of students with disabilities receiving instruction in the general education classroom setting (U.S. Department of Education, 2003). Direct instruction of social skills is imperative to ensure the academic and personal success of students; The research supports the direct instruction of discrete social skills behaviors …

Benefits Of Ict Adoption And Use In Regional General Medical Practices: A Pilot Study, Robert Macgregor, Peter Hyland, Charles Harvie, Boon-Chye Lee, Andrew Dalley, Sangeetha Ramu

Faculty of Informatics - Papers (Archive)

This paper presents a pilot study of benefits derived from information and communications technology (ICT) adoption and use in medical practices in regional Australia. The study involved 122 regional medical practitioners. The results show that like the more general small businesssector, the perception of certain benefits is associated with the size of the practice (in terms of employee levels) and/ or the gender of the respondent practitioner.

Conflicts Of Interest In Divisions Of General Practice, N Palmer, Annette J. Braunack-Mayer, Wendy Rogers, C Provis, G Cullity

Faculty of Social Sciences - Papers (Archive)

Community-based healthcare organisations manage competing, and often conflicting, priorities. These conflicts can arise from the multiple roles these organisations take up, and from the diverse range of stakeholders to whom they must be responsive. Often such conflicts may be titled conflicts of interest; however, what precisely constitutes such conflicts and what should be done about them is not always clear. Clarity about the duties owed by organisations and the roles they assume can help identify and manage some of these conflicts. Taking divisions of general practice in Australia as an example, this paper sets out to distinguish two main types …

General Methodology For Analysis And Modeling Of Trust Relationships In Distributed Computing, Weiliang Zhao, Vijay Varadharajan, George Bryan

Faculty of Engineering - Papers (Archive)

In this paper, we discuss a general methodology for analysis and modeling of trust relationships in distributed computing. We discuss the classification of trust relationships, categorize trust relationships into two layers and provide a hierarchy of trust relationships based on a formal definition of trust relationship. We provide guidelines for the analysis and modeling of trust relationships. We review operations on trust relationships and relative types of trust relationships in our previous work. We provide a set of definitions for the properties of direction and symmetry of trust relationships. In order to analyze and model the scope and diversity of …

Cape Wind: Public Values And Perceptions Application Of Contingent Valuation Method, Eric Steltzer

Master's Theses and Capstones

The Cape Wind proposal to build 130 turbines in Nantucket sound has been a central figure in development of renewable energy in New England. The aim of this study was two fold. First, the contingent valuation method was used to estimate an economic value the public has on policy for the preservation of Nantucket sound, within the scopes of the project. The second goal was to identify lessons that could be learned from the Cape Wind proposal and applied to future renewable energy projects in New England.

Results revealed that the public has a positive economic value for a policy …

Talking About Abortion: A Qualitative Examination Of Women's Abortion Experiences, Diana L. Dumais

Master's Theses and Capstones

The sociological literature on women's responses to the experience of abortion is remarkably sparse. This thesis seeks to contribute to redressing that research gap. I use semi-structured, in-depth interviews with twenty women from relatively diverse social backgrounds who have had abortions to explore the range of factors that they saw as being influential in their abortion decision and experience. Although the ages and the family circumstances of the women interviewed varied, and although some had more than one abortion, nevertheless, common themes emerged in their accounts of their abortion experiences. Among the most salient influences on my interviewees' experiences was …

Swing Voters? Roman Catholics From 1992 To 2004, Lori Gula Wright

Master's Theses and Capstones

This thesis evaluates whether Catholics are swing voters, how their voting behavior has changed from 1992 to 2004, and what issues are influencing their voting behavior. National Election Survey datasets from 1992, 1996, 2000 and 2004 are used. Two models are evaluated, the ethnoreligious model and the culture wars thesis. In addition, this thesis looks at whether Catholics tend to be single-issue voters.

The research and analysis of this thesis support the conclusion that Catholics are not swing voters and that their voting patterns are more similar to the general electorate than ever before. Although religious, class and cultural issues …

Elite Perceptions And The Adoption Of An Extremist Policy Of Genocide: A Comparative Case Study Of Armenia And Rwanda, Nicole Powell

Master's Theses and Capstones

The events leading up to the genocide that occurred in Rwanda in 1994 are similar to the events that led to the genocide that occurred in the Ottoman Empire in 1915. Economic and political crises plagued both states, international pressures to democratize weighed on both states, and both states were subject to ethnic polarization. This project examines those common factors preceding the Rwandan and Armenian genocides; and looks at elite's perception of a threat to their power because of the existence of those factors. Furthermore, the paper examines the relationship between the perception of a threat to elite power and …

Television Exposure, Feelings Of Fear And Confidence In The United States Government: Is The Government Using Media To Create A Culture Of Fear?, Janine Marie Soule

Master's Theses and Capstones

This study examines the relation between television media and fear as it pertains to the trust or confidence in the United States government. Using the fundamental hypothesis of cultivation theory (i.e., heavy viewers of television are more likely to believe that the world is a "mean and scary" place), the relation between the amount of television one watches, one's corresponding level of fear, and one's level of confidence in each branch of the United States federal government is examined. It is hypothesized that fear will have a mediating effect on the relation between heavy television consumption and respondents' confidence in …

Can Less Mean More In International Aid: Public Opinion Of International Assistance In Ghana, Michael Bena

Master's Theses and Capstones

This study examines public opinion of international aid in Ghana with a focus on a multivariate ordinary least squares regression model. It first examines the country of Ghana and the events that led to involvement with the International Monetary Fund under the Economic Recovery Program. After analyzing existing literature on satisfaction with government and economic programs, the study goes on to suggest what might drive citizen satisfaction with these programs. Using information from the Afrobarometer survey, this thesis proposes that public opinion of international aid programs is related to the tangible benefits they provide and the publics' perceptions of inequality …
