What If Daniel Ellsberg Hadn't Bothered?, Heidi Kitrosser Jan 2011

What If Daniel Ellsberg Hadn't Bothered?, Heidi Kitrosser

Articles

This article was written for the Indiana Law Review’s 2011 annual symposium entitled, “What If? Counterfactuals in Constitutional History.” As the article’s title suggests, it considers the impact of Daniel Ellsberg’s decision to leak the Pentagon Papers to the New York Times. The article takes some liberty with the topic of constitutional counterfactuals. Despite its author’s vast enjoyment of several classic movies and television episodes featuring parallel worlds, the article does not build a counterfactual universe in which Daniel Ellsberg never leaked the Pentagon Papers. It hints at such a world indirectly, however, by considering the difference that Ellsberg’s leak …

Magnetization Precession And Domain-Wall Structure In Cobalt-Ruthenium-Cobalt Trilayers, Zhen Li, Ralph Skomski, Sy-Hwang Liou, Steven Michalski, Mircea Chipara, Roger D. Kirby Jan 2011

Magnetization Precession And Domain-Wall Structure In Cobalt-Ruthenium-Cobalt Trilayers, Zhen Li, Ralph Skomski, Sy-Hwang Liou, Steven Michalski, Mircea Chipara, Roger D. Kirby

Physics & Astronomy Faculty Publications

The magnetization dynamics of Co(5 nm)/Ru/Co(5 nm) trilayers with Ru thicknesses from 0.3–0.6 nm is experimentally and theoretically investigated. The coupling between the Co layers is antiferromagnetic (AFM) and yields a stable AFM domain structure with frozen domain walls. Comparing high-resolution magnetic force microscopy (MFM) and pump-probe measurements, we analyze the behavior of the films for different field-strength regimes. For moderate magnetic fields, pump-probe measurements provide dynamic characterization of the coupled precessional modes in the GHz range. The dynamics at small fields is realized by the pinning of AFM domain walls at inhomogeneities. The MFM images yield a domain-wall width …

The Behavior Of Nanothermite Reaction Based On Bi2o3/Al, L. Wang, D. Luss, Karen S. Martirosyan

Physics & Astronomy Faculty Publications

We studied the impact of aluminum particle size and the thickness of surrounding alumina layer on the dynamic pressure discharge of nanothermite reactions in the Bi2O3/Al system. A pressure discharge from 9 to 13 MPa was generated using as-synthesized Bi2O3 nano-particles produced by combustion synthesis and Al nanoparticles with size from 3 μm to 100 nm. The maximum reaction temperature was measured to be ∼2700 °C. The estimated activation energy of the reaction was 45 kJ/mol. A very large (several orders of magnitude) difference existed between the rate of the pressure pulse release by nanothermite reactions and by thermite …

Responding To Our Own Transgressions: An Experimental Writing Study Of Repentance, Offense Rumination, Self-Justification, And Distraction, Charlotte Vanoyen-Witvliet, Nova G. Hinman, Julie J. Exline, Timothy Brandt

Faculty Publications

This between-subjects experiment focused on offender responses to their past interpersonal transgressions in self-identified Christian undergraduates (55 M, 85 F). Participants completed pre-post measures for one of four randomly assigned 20-minute writing conditions: repentance (i.e., writing about constructive sorrow, apology, restitution, behavior change), offense rumination (i.e., negative wallowing), self-justification (i.e., externalizing blame, minimizing costs), or distraction (i.e., daily details). Offense rumination and repentance writing included the most cost-oriented language; rumination had the most negative emotion language. Mixed within (pre vs. post) X between group ANOVA interactions yielded theoretically meaningful results. Repentance reduced self-condemnation and regret while increasing conciliatory motivations toward …

Neural Mechanisms Of Interference And Storage In Vibrotactile Working Memory, Tyler D. Bancroft Jan 2011

Neural Mechanisms Of Interference And Storage In Vibrotactile Working Memory, Tyler D. Bancroft

Theses and Dissertations (Comprehensive)

Vibrotactile working memory has attracted increasing attention in recent years. Substantial research into the neural correlates has been conducted, especially using single-cell paradigms in non-human primates (Romo & Salinas, 2003). The vibrotactile working memory system uses a relatively simple neural code for the representation of stimuli, making it possible to determine when stimulus information is present in the various cortical areas thought to be involved. In humans, vibrotactile working memory displays properties (such as overwriting mechanisms of interference) that make it an ideal system for testing general theories of working memory. In the present study, we demonstrate that vibrotactile working …

A Comparison Of Ancient Mediterranean Metal Structural Fittings, Evan Galen Sharp Jan 2011

A Comparison Of Ancient Mediterranean Metal Structural Fittings, Evan Galen Sharp

Theses and Dissertations (Comprehensive)

The construction of shelter is one of the basic activities that allows humans to survive. It is, moreover, one of the principal means by which we identify the occupation of a place by peoples who came before us. In the world of the ancient Mediterranean, methods and techniques flowed among populations as readily as any other commodity, and their manifestations bear witness to cultural contact as much as any transported religious, commercial, or military object. Moreover, since the construction of shelter is an activity common to all, functional techniques were a universally sharable knowledge. A collection and comparison of the …

You Can’T Go To Zion With A Carnal Mind: Slackness And Culture In The Music Of Yellowman, Brent Hagerman Jan 2011

You Can’T Go To Zion With A Carnal Mind: Slackness And Culture In The Music Of Yellowman, Brent Hagerman

Theses and Dissertations (Comprehensive)

Jamaican deejay Yellowman is best known for “slackness” lyrics centred on masculine heterosexual potency, sexist objectification of women and graphic sexual narratives. Yet a deeper look at Yellowman’s life and recorded output suggests that when his slackness is read in the context of Afro-Jamaican culture, reggae history and his Rastafarian faith, a more complex interpretation of his slackness is needed. This study will draw on Carolyn Cooper’s (2001) theory that slackness is a “metaphorical revolt against law and order, an undermining of consensual standards of decency” (p. 141). Whereas the term “culture” is used in reggae to depict music that …

Interprofessional Empathy In An Acute Healthcare Setting, Keith Adamson Jan 2011

Interprofessional Empathy In An Acute Healthcare Setting, Keith Adamson

Theses and Dissertations (Comprehensive)

Interprofessional collaboration is emerging as a key factor in reshaping healthcare practices in Canada over the last eight years. Collaboration in healthcare necessarily implies health providers sharing responsibility and partnering with each other in order to provide comprehensive patient care. A review of the empirical literature on teamwork in healthcare settings suggests that relationships between service providers remain conflictual and variable in their commitment to interprofessional collaboration (Zwarnstein & Bryant 2000). Recently, social psychologists have given considerable attention to the possibility that empathy could be used to improve intergroup attitudes and relations (Batson & Ahmad, 2009). Although empathy may be …

Interface Between Black-Footed Ferret Research And Operational Conservation., Dean E. Biggins, Travis M. Livieri, Stewart W. Breck Jan 2011

Interface Between Black-Footed Ferret Research And Operational Conservation., Dean E. Biggins, Travis M. Livieri, Stewart W. Breck

United States Department of Agriculture Wildlife Services: Staff Publications

Questions and problems that emerged during operational conservation of black-footed ferrets (Mustela nigripes)have been addressed by a wide variety of studies. Early results from such studies often were communicated orally during meetings of recovery groups and in written form using memoranda, unpublished reports, and theses. Typically, implementation of results preceded their publication in widely distributed journals. Many of these studies eventually were published in journals, and we briefly summarize the contents of 8 volumes and special features of journals that have been dedicated to the biology of ferrets and issues in ferret recovery. This year marks the 30th anniversary of …

White-Tailed Deer Incidents With U.S. Civil Aircraft, Kirsten M. Biondi, Jerrold L. Belant, James A. Martin, Travis L. Devault, Guiming Wang

United States Department of Agriculture Wildlife Services: Staff Publications

Aircraft incidents with ungulates cause substantial economic losses and pose risks to human safety. We analyzed 879 white-tailed deer (Odocoileus virginianus) incidents with United States civil aircraft from 1990 to 2009 reported in the Federal Aviation Administration National Wildlife Strike Database. During that time, deer incidents followed a quadratic response curve, peaking in 1994 and declining thereafter. There appeared to be some seasonal patterning in incident frequency, with deer incidents increasing overall from January to November, and peaking in October and November (30.7%). Most incidents (64.8%) occurred at night, but incident rates were greatest (P 0.001) at dusk. Landing-roll represented …

United States Department of Agriculture Wildlife Services: Staff Publications

Canids can be difficult to detect and their populations difficult to monitor. We tested whether hair samples could be collected from coyotes (Canis latrans) in Texas, USA and gray wolves (C. lupus) in Montana, USA using lure to elicit rubbing behavior at both man-made and natural collection devices. We usedmitochondrial and nuclearDNA to determine whether collected hair samples were from coyote, wolf, or nontarget species. Both coyotes and wolves rubbed on man-made barbed surfaces but coyotes in Texas seldom rubbed on hanging barbed surfaces. Wolves in Montana showed a tendency to rub at stations where natural material collection devices (sticks …

Modeling Connectivity Of Black Bears In A Desert Sky Island Archipelago, Todd C. Atwood, Julie K. Young, Jon P. Beckmann, Stewart W. Breck, Jennifer A. Fike, Olin E. Rhodes Jr., Kirby D. Bristow

United States Department of Agriculture Wildlife Services: Staff Publications

Landscape features such as rivers, mountains, desert basins, roads, and impermeable man-made structures may influence dispersal and gene flow among populations, thereby creating spatial structure across the landscape. In the US–Mexico borderland, urbanization and construction of the border fence have the potential to increase genetic subdivision and vulnerability to isolation in large mammal populations by bisecting movement corridors that have enabled dispersal between adjacent Sky Island mountain ranges. We examined genetic variation in black bears (Ursus americanus) from three regions in central and southern Arizona, US, to assess genetic and landscape connectivity in the US–Mexico border Sky Islands. We found …

Partitioning Of Anthropogenic Watering Sites By Desert Carnivores., Todd C. Atwood, Tricia L. Fry, Bruce Leland Jan 2011

Partitioning Of Anthropogenic Watering Sites By Desert Carnivores., Todd C. Atwood, Tricia L. Fry, Bruce Leland

United States Department of Agriculture Wildlife Services: Staff Publications

We investigated the role of water features as focal attractors for gray foxes (Urocyon cinereoargenteus), coyotes (Canis latrans), and bobcats (Felis rufus) in west Texas to determine if they were foci for interspecific interaction. Mixed effects models indicated that species partitioned use of water features spatially and temporally. Linear models indicated factors influencing relative activity at water features varied by species. For coyotes and bobcats, the water availability model, containing days since last rainfall and nearest-neighbor distance to water was best supported by the data, with relative activity increasing with time between rainfall and distance between waters. For gray foxes, …

Wild Dogma Ii: The Role And Implications Of Wild Dogma For Wild Dog Management In Australia., Benjamin L. Allen, Richard M. Engeman, Lee R. Allen Jan 2011

Wild Dogma Ii: The Role And Implications Of Wild Dogma For Wild Dog Management In Australia., Benjamin L. Allen, Richard M. Engeman, Lee R. Allen

United States Department of Agriculture Wildlife Services: Staff Publications

The studies of Allen (2011) and Allen et al. (2011) recently examined the methodology underpinning claims that dingoes provide net benefits to biodiversity by suppressing foxes and cats. They found most studies to have design flaws and/or observational methods that preclude valid interpretations from the data, describing most of the current literature as ‘wild dogma’. In this short supplement, we briefly highlight the roles and implications of wild dogma for wild dog management in Australia. We discuss nomenclature, and the influence that unreliable science can have on policy and practice changes related to apex predator management

Wild Dogma: An Examination Of Recent "Evidence" For Dingo Regulation Of Invasive Mesopredator Release In Australia., Benjamin L. Allen, Richard M. Engeman, Lee R. Allen Jan 2011

Wild Dogma: An Examination Of Recent "Evidence" For Dingo Regulation Of Invasive Mesopredator Release In Australia., Benjamin L. Allen, Richard M. Engeman, Lee R. Allen

United States Department of Agriculture Wildlife Services: Staff Publications

There is growing interest in the role that apex predators play in shaping terrestrial ecosystems and maintaining trophic cascades. In line with the mesopredator release hypothesis, Australian dingoes (Canis lupus dingo and hybrids) are assumed by many to regulate the abundance of invasive mesopredators, such as red foxes Vulpes vulpes and feral cats Felis catus, thereby providing indirect benefits to various threatened vertebrates. Several recent papers have claimed to provide evidence for the biodiversity benefits of dingoes in this way. Nevertheless, in this paper we highlight several critical weaknesses in the methodological approaches used in many of these reports, including …

Rock Pigeon Use Of Livestock Facilities In Northern Colorado: Implications For Improving Farm Bio-Security., James C. Carlson, Larry Clark, Michael F. Antolin, M. D. Salman Jan 2011

Rock Pigeon Use Of Livestock Facilities In Northern Colorado: Implications For Improving Farm Bio-Security., James C. Carlson, Larry Clark, Michael F. Antolin, M. D. Salman

United States Department of Agriculture Wildlife Services: Staff Publications

Rock pigeons (Columba livia) have been implicated in the spread of pathogens within commercial livestock facilities. Currently, there is no data characterizing pigeon habitat use and movement patterns within and among commercial livestock facilities. To better understand the capacity for pigeons to spread pathogens, we used radio-telemetry techniques to estimate the home-range, travel distance, activity, and habitat use of pigeons roosting on and off dairies and feedlots in western Weld County, Colorado. Our observations suggest that pigeons roosting on (resident) and off (nonresident) livestock facilities use habitat differently. Nonresident pigeons used larger home-range areas than did resident pigeons. Nonresident pigeons …

United States Department of Agriculture Wildlife Services: Staff Publications

Free-ranging wildlife, such as feral swine (Sus scrofa), harbor a variety of diseases that are transmissible to livestock and could negatively impact agricultural production. Information is needed regarding the exposure and infection rates of Mycobacterium bovis and many other diseases and parasites in feral swine occurring in the Texas border region. Our main objective was to determine exposure rates and possible infection rates of M. bovis in feral swine by opportunistically sampling animals from the Texas border region. From June to September 2010, we obtained samples from 396 feral swine and tested 98 samples for M. bovis by histopathology and …

Domestic Calf Mortality And Producer Detection Rates In The Mexican Wolf Recovery Area: Implications For Livestock Management And Carnivore Compensation Schemes., Stewart W. Breck, Bryan M. Kluever, Michael Panasci, John Oakleaf, Terry Johnson, Warren B. Ballard, Larry Howery, David L. Bergman

United States Department of Agriculture Wildlife Services: Staff Publications

Conserving large carnivores throughout the world will often require that they share the landscape with livestock. Minimizing depredations and increasing tolerance by livestock producers will be critical for conservation efforts. To investigate factors influencing calf mortality and producer detection rates (i.e., number of livestock killed by predators, found by producers, and correctly classified as to cause of death), we monitored radio-tagged domestic calves at two sites in the Mexican wolf recovery area (East Eagle [EE] and Adobe Ranch [AR]). Study areas differed in grazing practices, density of predators (mountain lions, black bears, coyotes, and Mexican wolves), and amount of effort …
