Comparing Hitler And Stalin: Certain Cultural Considerations, Phillip W. Weiss

Dissertations, Theses, and Capstone Projects

There is a great temptation to compare the Adolf Hitler and Joseph Stalin. This is true for two reasons: first, the careers of both men converged at the same point in history, thus doubling the impact both made and second, because the names Adolf Hitler and Joseph Stalin have become metaphors for ideologies and crimes that today are reviled. The question then arises: who was worse, Hitler or Stalin? This project shows that there is no viable, credible, definitive, or final answer to this question, and that prevailing attitudes about Hitler and Stalin have become so ingrained in contemporary society …

Bernard Yack's Nationalism and the Moral Psychology of Community (2012) was the subject of the eighth in a long‐running series of debates hosted by the Association for the Study of Ethnicity and Nationalism (ASEN) and the journal Nations and Nationalism in November of 2013. These debates bring together the authors of recent important works in the study of nationalism and ethnicity with appropriate scholars to explore the questions they have provoked. On this occasion Professor Yack was joined by Professor Chandran Kukathas and Professor David Miller.

Treatment Of Industrial Wastewater Using Electrocoagulation, Shereen W. Hasan

Theses

The aim of this thesis was to evaluate the potential use of electrocoagulation in the treatment of carbide slurry, which is wastewater generated during the production of acetylene. Several experiments using an electrochemical batch reactor were carried out at different current densities, ranging between 140-290 A/m². Pure air (EA system) and 10% of carbon dioxide in air (CA system) were supplied to ensure good mixing and solution homogeneity. Aluminum plates were used as electrodes, spaced apart and connected to a DC power supply. After 3 hours, samples from treated effluent and waste slurry were collected and analyzed for …

Assessment Of Groundwater Recharge From The Dam Of Wadi Al-Jizzi, Sultanate Of Oman, Rashid Said Al-Kindi

Theses

Water is the most precious resource in arid and semi-arid countries including the Sultanate of Oman. In such countries, groundwater is regarded a major source of water. However, the long-term yield of aquifers should be evaluated. Annual recharge of groundwater resources, in such areas, is generally small but groundwater levels may also recover dramatically during wet years.

Due to the increase in population and the associated increase in agricultural and industrial activities groundwater abstraction from the different aquifers in Oman has increased tremendously since the mid-1970s. This over exploitation of the groundwater resources has led to a considerable decline in …

Development Of A Process For Producing Biodiesel From Microalgae Lipids With Supercritical Carbon Dioxide Extraction And Enzyme-Catalyzed Transesterification, Hanifa Easa Taher Al Belooshi

Theses

Lipids were extracted from microalgae using supercritical carbon dioxide (SC-CO2), and used for enzymatic biodiesel production in SC-CO2. The growth of several fresh water and marine strains was tested under aeration with different CO2 enrichments. The highest growth found was for Chlorella sp. grown at 27 oC, 1 % CO2 enrichment and 460 mM NaCl concentration, at which carbon fixation rate was 1.7 g L-1 d-1. The highest enhancement of lipids content by nitrogen starvation was found with Scenedesmus sp., but with a lower growth rate. Two step cultivation of Scenedesmus sp. was carried out in a 5 L internally-illuminated …

Using M-Learning As A Means To Promote Self-Direction And Engagement In Apprenticeship Theoretical Lessons, Alan O'Donnell

Irish Journal of Academic Practice

An exploratory case study was carried out to investigate if the use of mobile phones as a tool for learning could address concerns over the current learning of the carpentry and joinery apprentices in the Dublin Institute of Technology. The concerns are regarding a lack of learner self-direction and engagement with the learning content. A high level of mobile phone usage was apparent among the apprentice cohort. It was decided to take advantage of the potential learning opportunity offered by mobile technologies to promote the learning and engagement of the apprentices. Towards this goal, a compatible resource was developed, hosting …

Virtual Classrooms In The Workplace: An Implementation Study, Angela Walsh

Irish Journal of Academic Practice

The use of e-learning by corporate organisations as a means to deliver training to employees has grown significantly in recent years. Improvements in technology have meant that corporate Learning and Development (L&D) departments now have more options available to them and the use of web 2.0 technologies is increasingly being explored as a method of delivering training to employees both asynchronously and synchronously. Research into elearning in workplaces is limited and tends to consist of anecdotal accounts from organisations with a US focus (Newton & Ellis, 2005). This case study explores the implementation of web conferencing software as a means …

The Case For Human-Centric Personal Analytics, Youngki Lee, Rajesh Krishna Balan

Research Collection School Of Computing and Information Systems

The rich context provided by smartphones has enabled many new context-aware applications. However, these applications still need to provide their own mechanisms to interpret low-level sensing data and generate high-level user states. In this paper, we propose the idea of building a personal analytics (PA) layer that will use inputs from multiple lower layer sources, such as sensor data (accelerometers, gyroscopes, etc.), phone data (call logs, application activity, etc.), and online sources (Twitter, Facebook posts, etc.) to generate high-level user contextual states (such as emotions, preferences, and engagements). Developers can then use the PA layer to easily build a new …

The Perception Of Emotion From Acoustic Cues In Natural Speech, John Snel

Doctoral

Knowledge of human perception of emotional speech is imperative for the development of emotion in speech recognition systems and emotional speech synthesis. Owing to the fact that there is a growing trend towards research on spontaneous, real-life data, the aim of the present thesis is to examine human perception of emotion in naturalistic speech. Although there are many available emotional speech corpora, most contain simulated expressions. Therefore, there remains a compelling need to obtain naturalistic speech corpora that are appropriate and freely available for research. In that regard, our initial aim was to acquire suitable naturalistic material and examine its …

Modulation Of Hcn Channels In Lateral Septum By Nicotine, Sodikdjon A. Kodirov, Michael Wehrmeister, Luis V. Colom

Health & Biomedical Sciences Faculty Publications

The effects of addictive drugs most commonly occur via interactions with target receptors. The same is true of nicotine and its multiple receptors in a variety of cell types. However, there are also side effects for given substances that can dramatically change cellular, tissue, organ, and organism functions.

In this study, we present evidence that nicotine possesses such properties, and modulates neuronal excitability. We recorded whole-cell voltages and currents in neurons situated in the dorsal portion of the lateral septum in acute coronal brain slices of adult rats. Our experiments in the lateral septum revealed that nicotine directly affects HCN …

Should Organizations Promoting Dangerous Sports Enjoy Maximum Tax Benefits?, William A. Drennan

San Diego Law Review

Perhaps one in every 1000 BASE jumps results in death, and the fatality and injury rates for BASE jumping may be forty-three times higher than for standard skydiving. Some other new sports are extremely dangerous. In addition, some medical researchers are finding that repeated jolts to the head in traditional contact sports correlate to midlife Alzheimer’s disease, suicide, depression, inability to work or function without a caregiver, and early death from the brain disease chronic traumatic encephalopathy (CTE). “[N]early a quarter of a million new patients turn up each year with long-term deficits resulting from . . . so-called mild …

Exploiting Phytochemicals For Developing Sustainable Crop Protection Strategies To Withstand Climate Change: Example From Africa, Zeyaur R. Khan, Charles A.O. Midega, Jimmy O. Pittchar, John A. Pickett

All Peer-Reviewed Publications

Africa suffers chronic food insecurity resulting from ravaging effects of insect pests, weeds and poor soil fertility, with rising poverty and increasingly dry and hot weather conditions associated with climate change further aggravating this situation. Scientists at the International Centre of Insect Physiology and Ecology (icipe) together with national and international partners have developed a platform technology, 'push-pull', based on locally available companion plants for integrated management of these constraints by exploiting innate plant defence systems including secondary metabolism. This involves intercropping cereal crops, the main staple and cash crops for millions of smallholder farmers in the continent, with forage …

Law In The Flesh: Tracing Legitimation's Origin To The Act Of Killing?, Richard Sherwin

Articles & Chapters

A proper respect for civil order does not mandate the elision of political violence. To the contrary, civility requires that we explore the exercise of violence at the beginning of state sovereignty. To forget, or repress, originary violence invites its return. That is why, with its insistence upon rational calculation and the neutralization of desire, the vast cleanup operation of liberal theory is bound to fail.

Notes: Bed-Site Selection By Neonatal White-Tailed Deer In Central North Dakota, Brian A. Schaffer, Jonathan A. Jenks, Troy W. Grovenburg, William F. Jensen

The Prairie Naturalist

Understanding bed-site selection and vegetation characteristics provides valuable information for population management (Verme 1977, Huegel et al. 1985a, Nelson and Woolf 1987). Predation and other natural-caused mortalities of white-tailed deer (Odocoileus virginianus) neonates are most likely to occur within the first 60 days of life; a time period when selected habitat characteristics are vital to survival (Verme 1977, Hue- gel et al. 1985a, Nelson and Woolf 1987, Grovenburg et al. 2010). Prior to the study of Grovenburg et al. (2010), limited research had been completed on the bed-site selection of neonatal white-tailed deer in the grasslands of the Northern Great …

Grazing Method Effects On Forage Production, Utilization, And Animal Performance On Nebraska Sandhills Meadow, Miles D. Redden

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Mob grazing using ultrahigh stocking densities is promoted as a tool to increase the health and productivity of grasslands by increasing nutrient cycling and soil organic matter. Mob grazing can be defined as a strategy in which area available to grazing animals is restricted to achieve stocking densities of 200,000 kg/ha or greater. Objectives were to determine herbage production, utilization, and cattle weight gains among ultrahigh stocking density grazing and more conventional grazing methods on a Sandhills subirrigated meadow. Treatments included two replications of each of the following: four-pasture rotational grazing with two occupations per pasture in an 80-day grazing …

Developing Defined And Scalable 3d Culture Systems For Culturing Human Pluripotent Stem Cells At High Densities, Yuguo Lei, Daeun Jeong, Jifang Xiao, David V. Schaffer

Department of Chemical and Biomolecular Engineering: Faculty Publications

Human pluripotent stem cells (hPSCs)—including embryonic stem cells (hESCs) and induced pluripotent stem cells (hiPSCs)—are very promising candidates for cell therapies, tissue engineering, high throughput pharmacology screens, and toxicity testing. These applications require large numbers of high quality cells; however, scalable production of human pluripotent stem cells and their derivatives at a high density and under well-defined conditions has been a challenge. We recently reported a simple, efficient, fully defined, scalable, and good manufacturing practice (GMP) compatible 3D culture system based on a thermoreversible hydrogel for hPSC expansion and differentiation. Here, we describe additional design rationale and characterization of this …

What Are Blue Ross's Geese?, Paul A. Johnsgard

Nebraska Bird Review

The existence of blue morph ("phase") Ross's Geese (Chen rossii) was first well documented by McLandress & McLandress (1979). They reported on several blue-morph birds seen and collected in California and Canada that morphologically appeared to be pure Ross's Geese and on others with intermediate traits that appeared to be hybrids with Lesser Snow Geese (Chen caerulescens caerulescens). They also noted that in the California wintering grounds counts held during 1976–77 there were only 3 blue morphs (0.008 percent) among the 38,825 Ross's Geese counted. At that time, only 0.02 percent of the Lesser Snow Geese …

How Adolescents Perceive Their Parents' Communication About Sex: Toward Reducing Adolescent Sexual Risk, Amanda J. Holman

Department of Communication Studies: Dissertations, Theses, and Student Research

The “sex talk” is often one of the most challenging conversations for parents and children during adolescence. Research has established that parent-adolescent communication about sex can greatly reduce adolescents’ sexual risk (Guilamo-Ramos et al., 2012; Miller, Benson, & Galbraith, 2001). However, many parents still avoid these conversations due to uncertainty or lack of confidence in how to best educate their children on topics such as sexual health and relationships. Plus, little is known about family communication about sex from the adolescent perspective. In order to develop more comprehensive strategies for parents to engage in these challenging conversations, the present dissertation …

New Species Records And Changes In Abundance Of Waterfowl In Northwest Greenland, K. K. Burnham, D. R. Sinnett, J. A. Johnson, J. L. Burnham, J. A. Baroch

United States Department of Agriculture Wildlife Services: Staff Publications

Breeding populations of Nearctic and Palearctic waterfowl have undergone significant changes in abundance and distribution over the past 50 years. The Avanersuaq District in northwest Greenland is home to an assemblage of waterfowl from both geographic areas; however, minimal historic or current information is available on species abundance. In 2008 and 2009, we conducted field surveys in Greenland from 76.00_ to 77.35_N for breeding and non-breeding waterfowl and have collected anecdotal field notes of avian observations over a 20-year period (1993–2012). During these periods, we documented the first observation of a Ross’s goose (Chen rossii) and the first confirmed breeding …

Abstract

Background

Cystic echinococcosis (CE) is a globally distributed cestode zoonosis that causes hepatic cysts. Although Echinococcus granulosus sensu stricto (s.s.) is the major causative agent of CE worldwide, recent molecular epidemiological studies have revealed that E. canadensis is common in countries where camels are present. One such country is Mongolia.

Methodology/Principal Findings

Forty-three human hepatic CE cases that were confirmed histopathologically at the National Center of Pathology (NCP) in Ulaanbaatar (UB) were identified by analysis of mitochondrial cox1 gene as being caused by either E. canadensis (n = 31, 72.1%) or E. granulosus s.s. ( …

Characterization Of Winter Microbial Communities In The Purple Pitcher Plant (Sarracenia Purpurea), Reid Jeffrey Tornquist

Master's Theses and Doctoral Dissertations

Carnivorous pitcher plants trap insects in cone-shaped leaves and digest them to gain vital nutrients. For digestion to occur, plants in the genus Sarracenia require mutualistic microorganisms living in their leaves. Few studies have examined how these communities change over time. This study specifically examines the bacterial composition in the most widely distributed species, Sarracenia purpurea, in the winter. The leaves of this plant species live for several years, and it is unknown whether microbes overwinter in pitcher fluid or if community structure must be reestablished each spring. This study aims to characterize the winter microbiome in two population …

Various applications of object detection include video surveillance, traffic monitoring, digital libraries, navigation, human computer interaction, etc. The challenges involved with detecting real world objects include the multitude of colors, textures, sizes, and cluttered or complex backgrounds making objects difficult to detect.

This thesis contributes to the exploration of various dimensionality reduction techniques on descriptors for establishing an object detection system that achieves the best trade-offs between performance and speed. Histogram …

New Frontiers For The Nfil3 Bzip Transcription Factor In Cancer, Metabolism And Beyond, Megan Keniry, Robert K. Dearth, Michael W. Persans, Ramon Parsons

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

The bZIP transcription factor NFIL3 (Nuclear factor Interleukin 3 regulated, also known as E4 binding protein 4, E4BP4) regulates diverse biological processes from circadian rhythm to cellular viability. Recently, a host of novel roles have been identified for NFIL3 in immunological signal transduction, cancer, aging and metabolism. Elucidating the signaling pathways that are impacted by NFIL3 and the regulatory mechanisms that it targets, inhibits or activates will be critical for developing a clearer picture of its physiological roles in disease and normal processes. This review will discuss the recent advances and emerging issues regarding NFIL3-mediated transcriptional regulation of CEBPb and …
