Systematic Analysis Of Double-Ionization Dynamics Based On Four-Body Dalitz Plots, Daniel Fischer, Michael Schulz, Katharina R. Schneider, Marcelo F. Ciappina, Tom Kirchner, Aditya H. Kelkar, S. Hagman, Manfred Grieser, Kai Uwe Kuhnel, Robert Moshammer, Joachim Hermann Ullrich Dec 2009

Systematic Analysis Of Double-Ionization Dynamics Based On Four-Body Dalitz Plots, Daniel Fischer, Michael Schulz, Katharina R. Schneider, Marcelo F. Ciappina, Tom Kirchner, Aditya H. Kelkar, S. Hagman, Manfred Grieser, Kai Uwe Kuhnel, Robert Moshammer, Joachim Hermann Ullrich

Physics Faculty Research & Creative Works

We report on an experimental and theoretical systematic study of double ionization of helium by ion impact in terms of four-particle Dalitz plots. Several collision systems covering abroad range of perturbation parameters η (projectile charge to speed ratio) were investigated. With increasing η we observe a systematic trend from features, characteristic to correlated double-ionization mechanisms, to signatures of higher-order processes not requiring electron-electron correlations [the mechanism called "two-step-two projectile-electron interaction" (TS-2)]. The data for the largest η can qualitatively be amazingly well described by a simple model only including the TS-2 mechanism.


Ddr Erziehung In Der Ansicht Von Christa Wolf In Der Geteilte Himmel, Timothy Walker Dec 2009

Ddr Erziehung In Der Ansicht Von Christa Wolf In Der Geteilte Himmel, Timothy Walker

The Kennesaw Tower Undergraduate Foreign Language Research Journal

In this paper I examined Christa Wolf’s portrayal of education in East Germany through a study of her book Der geteilte Himmel. The goal of education in the GDR was to create faithful socialist workers. Rita Seidel, the main character in Der geteilte Himmel, chose to study education in order to be with her boyfriend, Manfred, in the city. As she continued her socialist studies, her goal changed to forwarding socialism in the GDR. Additionally, through my research on education in the GDR, it becomes clear that teachers were valuable to the state; this is not portrayed in Wolf’s story. …

Assessment Of Internationalised Domain Name Homograph Attack Mitigation, Peter Hannay, Christopher Bolan Dec 2009

Assessment Of Internationalised Domain Name Homograph Attack Mitigation, Peter Hannay, Christopher Bolan

Australian Information Security Management Conference

With the advent of internationalised domains the threat posed by non-english character sets has eventuated. Whilst this phenomenon remains well known in the development and internet industry the actual implementations of popular applications have been tested to determine their resilience to homograph based attack. The research found that most provided features that overcome such attacks, but there remain a few notable exceptions. Should an attacker take advantage of such oversights a victim would likely not be able to spot a fraudulent site or email and thus provide a perfect platform for subsequent attack.

Further Development Of The Overload Risk Index, An Indicator Of System Vulnerability, John Rossmaier, Badrul Chowdhury Dec 2009

Further Development Of The Overload Risk Index, An Indicator Of System Vulnerability, John Rossmaier, Badrul Chowdhury

Electrical and Computer Engineering Faculty Research & Creative Works

This paper develops and expands on a previously devised vulnerability index in an attempt to make the index more robust in describing a power system's total vulnerability level. the previous index was derived using a dc load flow analysis using line outage distribution factors and Monte Carlo simulation that incorporated the unavailability rates of the transmission lines within the system. the updated index incorporates the following improvements: (a) tests to determine bus islanding in the system, (b) steady-state stability tests, (c) an optimal power flow to determine a more accurate steady-state point of operation, (d) ac analysis for a greater …


The Prevalence Of Osteoarthritis In Wild Vs Captive Great Ape Skeletons, Demelza J. Poe Dec 2009

The Prevalence Of Osteoarthritis In Wild Vs Captive Great Ape Skeletons, Demelza J. Poe

Anthropology ETDs

This research examined whether the prevalence and skeletal distribution of osteoarthritis (OA) differed between wild and captive great ape skeletons. A secondary, but important, aspect of this research focused on the development of improved aging techniques based on methods commonly used on human osteological samples. Tests were conducted pertaining to the effect that wild versus captive status, sex, and species has on vertebral body lipping, marginal lipping, and eburnation. Age was considered a co-factor. Of the aging methods examined, use of the basilar suture to distinguish between adult and old adult specimens proved to be very imprecise. The ribs and …

Biological Sciences Collection Development Policy, Jacquelyn Petzold Dec 2009

Biological Sciences Collection Development Policy, Jacquelyn Petzold

University of Nebraska-Lincoln Libraries: Collection Development Policies

The biological sciences collection exists to support the teaching, research, and service functions of the School of Biological Sciences and the University of Nebraska-Lincoln community. The public may benefit from the biological sciences collection, although specific materials are not collected to meet their needs. Biology-related materials not available in the library’s collection are generally readily available through Interlibrary Loan. The collection is focused on the biologically-based subsections of the Q Library of Congress call number range, although the heavily interdisciplinary nature of scientific study necessitates some overlap with R, S, T, and other areas.

Coping Methods And Meaning Making Of Liberian Refugees In The Buduburam Refugee Camp Of Ghana, Abena Gyamfuah Sarfo-Mensah Dec 2009

Coping Methods And Meaning Making Of Liberian Refugees In The Buduburam Refugee Camp Of Ghana, Abena Gyamfuah Sarfo-Mensah

Honors Scholar Theses

The mental health of war-impacted individuals has been an issue of growing concern to many researchers and practitioners internationally (Miller, Kulkarni, & Kushner, 2006). According to the United Nations High Commissioner for Refugees (2006a), Africans are disproportionately impacted by conflict-related displacement. To date, however, much of the research on the mental health of refugees has been based mostly on Western views of health and trauma. The current study is a mixed-methods investigation of stressors, coping strategies, and meaning making of Liberian refugees in the Buduburam Refugee Camp of Ghana. Results from the Brief COPE, focus groups, and semi-structured ethnographic interviews …


Should President Omar Al-Bashir Of Sudan Be Charged And Arrested By The International Criminal Court?, Alex De Waal, Gregory H. Stanton Dec 2009

Should President Omar Al-Bashir Of Sudan Be Charged And Arrested By The International Criminal Court?, Alex De Waal, Gregory H. Stanton

Genocide Studies and Prevention: An International Journal

The recent activity at the International Criminal Court (ICC) at The Hague con- cerning the case of President Omar al-Bashir and the crisis in Darfur has set off a firestorm of commentary amongst international lawyers, human rights activists, genocide scholars, experts on Sudan, and journalists, among others. Some argue that the ICC prosecutor, Luis Moreno-Ocampo, was correct in charging al-Bashir with genocide and crimes against humanity; others believe that he had little to no grounds for doing so. Furthermore, while some see the prosecutor’s charges of geno- cide as questionable, at best, and highly counterproductive, if not dangerous, at worst, …


Book Review: Alex De Waal, Ed., War In Darfur And The Search For Peace, John H. Weiss Dec 2009

Book Review: Alex De Waal, Ed., War In Darfur And The Search For Peace, John H. Weiss

Genocide Studies and Prevention: An International Journal

War in Darfur and the Search for Peace, edited by Alex de Waal, offers an enlightening tour of the contested intellectual terrain encountered by those who have concerned themselves with the fate of Sudan’s westernmost region since the escalation of the conflict there at the beginning of the twenty-first century. The fact that one is contri- buting to a journal dedicated to preventing the radical diminishing of peoples and cul- tures, aka genocide, guides the selection of parts of the volume under review that will receive special attention here. That it is an attempt to understand the failure of nego- …

A Case Study Of How A Large Multilevel Efl Writing Class Experiences And Perceives Multiple Interaction Activities, Hsien-Chuan Lin Dec 2009

A Case Study Of How A Large Multilevel Efl Writing Class Experiences And Perceives Multiple Interaction Activities, Hsien-Chuan Lin

Dissertations

The purpose of this study was to examine students' experiences and perceptions of multiple interaction activities (self-directed, peer, and teacher feedback) implemented in a large multilevel EFL writing class in one private technological university in the southern part of Taiwan. Large size writing classes, quite common in private institutions of higher education in Taiwan, cannot be effectively operated to meet individual students' needs in improving their writing performance. Low achievers have difficulties in keeping up with competent writers in learning writing skills while advanced students complain of their learning too little from the class. This research, based on the activity …


The Relationship Between Web Accessibility Policy And Practice In Postsecondary Institutions, Michael Whitney Dec 2009

The Relationship Between Web Accessibility Policy And Practice In Postsecondary Institutions, Michael Whitney

Dissertations

From computer workstations to the world of the web, statutes and policies have afforded students with disabilities the right to participate in postsecondary education in a non-discriminatory manner. Automatic doors and adjustable tables are a commonplace on campuses and represent prime examples of accessible policy adherence, but what affect do accessible website design policies have on practice? The answer is monumental for the students with disabilities that rely on the integration of electronic curb cuts into institutional websites. In 2006, Illinois Board of Higher Education required public postsecondary institutions to develop and implement a website policy, report on the accessibility …


A Critical Analysis Of Rural Teachers' Usage Of Online Communities, Sherri A. Snider Dec 2009

A Critical Analysis Of Rural Teachers' Usage Of Online Communities, Sherri A. Snider

Dissertations

The purpose of this study was to analyze data related to rural teachers' use of online communities. Rural teachers are often isolated in their practice and sometimes have difficulty connecting with other teachers with their same assignments or needs due to their professional setting. As Internet availability increases and online communities proliferate, teachers have more opportunity than ever to seek personal and professional support in virtual relationships when face-to-face ones are not easily available. In small schools such as the ones included in this study, teachers can become burned out as they perform the difficult task of teaching with few …


The Impact Of Training And Its Integration In The Firm's Business Strategies On The Firm's Competitiveness, Vichet Sum Dec 2009

The Impact Of Training And Its Integration In The Firm's Business Strategies On The Firm's Competitiveness, Vichet Sum

Dissertations

The problem of the present study was to determine training professionals' perceptions of their awareness of and involvement in the integration of training in the firm's business strategies and the impact of training on the firm's competitiveness. The analysis of data obtained from the online survey of 111 participants who were training professionals employed in small, medium, and large firms across three different industries - service, retailing, and manufacturing - revealed that more than 50% of the participants indicated that they either had some understanding of or understood in depth the integration of training in their firms' business strategies. And …


Ludwig Van Beethoven's Orchestration Of The Trombone, Daniel R. Cloutier Dec 2009

Ludwig Van Beethoven's Orchestration Of The Trombone, Daniel R. Cloutier

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ludwig Van Beethoven is considered one of the first composers to fully realize the wide-ranging performance potential of the trombone. Although the instrument had already been scored in sacred and operatic works by major composers (and symphonies by lesser-known composers), it was Beethoven who was considered to be the first to truly emancipate the trombone from its sacred and operatic boundaries and write for it in various secular, choral, and even chamber music genres. In this paper, every composition of Beethoven's that includes trombones is examined. The historical context of each individual work will be established, along with any general …
