The Quantum Dynamic Capacity Formula Of A Quantum Channel, Mark M. Wilde, Min Hsiu Hsieh Jan 2012

The Quantum Dynamic Capacity Formula Of A Quantum Channel, Mark M. Wilde, Min Hsiu Hsieh

Faculty Publications

The dynamic capacity theorem characterizes the reliable communication rates of a quantum channel when combined with the noiseless resources of classical communication, quantum communication, and entanglement. In priorwork,we proved the converse part of this theorem by making contact with many previous results in the quantum Shannon theory literature. In this work, we prove the theorem with an "ab initio" approach, using only the most basic tools in the quantum information theorist's toolkit: the Alicki-Fannes' inequality, the chain rule for quantum mutual information, elementary properties of quantum entropy, and the quantum data processing inequality. The result is a simplified proof of …

Subordinate Male Cichlids Retain Reproductive Competence During Social Suppression, Jacqueline M. Kustan, Karen P. Maruska, Russell D. Fernald Jan 2012

Subordinate Male Cichlids Retain Reproductive Competence During Social Suppression, Jacqueline M. Kustan, Karen P. Maruska, Russell D. Fernald

Faculty Publications

Subordinate males, which are excluded from reproduction often save energy by reducing their investment in sperm production. However, if their position in a dominance hierarchy changes suddenly they should also rapidly attain fertilization capability. Here, we asked how social suppression and ascension to dominance influences sperm quality, spermatogenesis and reproductive competence in the cichlid Astatotilapia burtoni, where reproduction is tightly coupled to social status. Dominant territorial (T) males are reproductively active while subordinate non-territorial (NT) males are suppressed, but given the opportunity, NT males will perform dominance behaviours within minutes and attain T male testes size within days. Using the …

The Phylogenetic Distribution And Ecological Role Of Carbon Monoxide Oxidation In The Genus Burkholderia, Carolyn F. Weber, Gary M. King Jan 2012

The Phylogenetic Distribution And Ecological Role Of Carbon Monoxide Oxidation In The Genus Burkholderia, Carolyn F. Weber, Gary M. King

Faculty Publications

Burkholderia is a physiologically and ecologically diverse genus that occurs commonly in assemblages of soil and rhizosphere bacteria. Although Burkholderia is known for its heterotrophic versatility, we demonstrate that 14 distinct environmental isolates oxidized carbon monoxide (CO) and possessed the gene encoding the catalytic subunit of form I CO dehydrogenase (coxL). DNA from a Burkholderia isolate obtained from a passalid beetle also contained coxL as do the genomic sequences of species H160 and Ch1-1. Isolates were able to consume CO at concentrations ranging from 100 ppm (vol/vol) to sub-ambient (< 60 ppb (vol/vol)). High concentrations of pyruvate inhibited CO uptake (> 2.5 mM), but mixotrophic consumption of CO and pyruvate occurred …

Host Interferon-Γ Inducible Protein Contributes To Brucella Survival., Jennifer A. Ritchie, Adam Rupper, James A. Cardelli, Bryan H. Bellaire Jan 2012

Host Interferon-Γ Inducible Protein Contributes To Brucella Survival., Jennifer A. Ritchie, Adam Rupper, James A. Cardelli, Bryan H. Bellaire

Faculty Publications

Brucella spp. are highly adapted intracellular pathogens of mammals that cause chronic infections while surving and replicating in host monocytes and macrophages. Although monocytes are normally susceptible to infection, pretreatment with pro-inflammatory cytokine interferon-γ (IFN-γ) activates cellular defense mechanisms that increase intracellular killing of Brucella and prevents bacterial replication. We examined the contribution of the IFN-γ inducible GTPase, LRG-47, to B. abortus 2308 infection in in vitro and in vivo murine models. Infecting non-activated macrophages from LRG-47(-/-) mice revealed that loss of this host protein negatively effected the intracellular survival and replication of IgG opsonized B. abortus. In contrast, survival …

The Origin And In Situ Identification Of Uncultured Gut Bacteria In Fourth-Instar Larvae Of The Red Imported Fire Ant, Solenopsis Invicta (Hymenoptera: Formicidae), Albert H. Lee, Linda Hooper-Bui

Faculty Publications

This study corroborated the findings of Lee et al. (2008) and relied on culture-independent techniques, particularly 16SrDNA sequencing. Results from the study demonstrated that ants in captivity completely change their gut bacterial diversity strongly supports the conclusion that fire ant gut bacteria are environmental in origin. Bacteria in the fourth-instar larvae were present because they were consumed with food sources. From molecular data, a differing list of bacteria from each colony with different branching and clustering among bacterial clades in the phylogenetic trees were found. Different bacterial diversity and evenness was found in all colonies, which provided evidence against the …

Topology Of Random 2-Complexes, D. Cohen, A. Costa, M. Farber, T. Kappeler Jan 2012

Topology Of Random 2-Complexes, D. Cohen, A. Costa, M. Farber, T. Kappeler

Faculty Publications

We study the Linial-Meshulam model of random two-dimensional simplicial complexes. One of our main results states that for p≪n-1 a random 2-complex Y collapses simplicially to a graph and, in particular, the fundamental group π1(Y) is free and H2(Y)=0, asymptotically almost surely. Our other main result gives a precise threshold for collapsibility of a random 2-complex to a graph in a prescribed number of steps. We also prove that, if the probability parameter p satisfies p≫n-1/2+ε, where ε>0, then an arbitrary finite two-dimensional simplicial complex admits a topological embedding into a random 2-complex, with probability tending …

Dialogic Conversations In An Embedded Literacy Assessment Field Experience, Lucy Spence, Amy Donnally, Amy Johnson Lachuk, Marcie Ellerbe Jan 2012

Dialogic Conversations In An Embedded Literacy Assessment Field Experience, Lucy Spence, Amy Donnally, Amy Johnson Lachuk, Marcie Ellerbe

Faculty Publications

Preservice teachers often come into teacher education programs with a positivist view of assessment, which may have developed during their own schooling experiences. For this reason, purposefully constructed course work and field experiences must be offered to enable them reframe their conceptions of literacy assessment and to complicate the assessment practices that have become most familiar to them. This paper examines a course in which, the aim is to intentionally counter the positivist testing culture and invest in helping preservice teachers understand assessment as a multi-faceted, dynamic process of inquiry.

Not Everyone Works For Biglaw: A Response To Neil J. Dilloff, Louis N. Schulze Jr., Lawrence Friedman Jan 2012

Not Everyone Works For Biglaw: A Response To Neil J. Dilloff, Louis N. Schulze Jr., Lawrence Friedman

Faculty Publications

In a law review article entitled "The Changing Cultures and Economics of Large Law Firm Practice and Their Impact on Legal Education," DLA Piper partner Neil J. Dilloff details recent changes in the way that BigLaw does business. He then suggests a number of improvements in legal education ostensibly compelled by the new economic realities of large firm practice. While many of Attorney Dilloff's suggestions make very good sense, several problems exist. In this short essay, we take the position that law schools should not pattern current reforms solely on the needs of BigLaw. Instead, we suggest that reforming legal …

Knowing Your Partner Is Not Enough: Spousal Importance Moderates The Link Between Attitude Familiarity And Ambulatory Blood Pressure, Wendy C. Birmingham, Bert N. Uchino, David M. Sanbonmatsu

Faculty Publications

Close relationships have been linked to cardiovascular morbidity and mortality. More research is needed, however, on the social and biological processes responsible for such links. In this study, we examined the role of relationship-based attitudinal processes (i.e., attitude familiarity and partner importance) on ambulatory blood pressure during daily life. Forty-seven married couples completed a questionnaire regarding their own attitudes, perceptions of their partner’s attitudes, and perceptions of partner importance. They also underwent a 1-day ambulatory assessments of daily spousal interactions and blood pressure. Partner importance was related to better interpersonal functioning (e.g., partner responsiveness) and lower ambulatory systolic blood pressure. …

Performance Monitoring Following Conflict: Internal Adjustments In Cognitive Control?, Scott A. Baldwin, Michael J. Larson, Peter E. Clayson Jan 2012

Performance Monitoring Following Conflict: Internal Adjustments In Cognitive Control?, Scott A. Baldwin, Michael J. Larson, Peter E. Clayson

Faculty Publications

The purpose of this study was to investigate the effects of strategic conflict-related adjustments in cognitive control processes on indices of performance monitoring. Previous research has examined the ability of parametric task-related manipulations to bias attention to errors; however, the present study sought to elucidate the effects of internal adjustments in control mediated by the anterior cingulate cortex on error-related conflict processing. High-density event-related potentials (ERPs) were obtained from 124 healthy individuals (68 female, 66 male) during a modified Eriksen flanker task. Behavioral measures (i.e., error rates, response times [RTs]) and N2 amplitudes showed significant conflict adaptation (i.e., previous-trial congruencies …

Ballistic Imaging Of Sprays At Diesel Relevant Conditions, Jason M. Porter, S. P. Duran, T. E. Parker

Faculty Publications

Diesel engines are an important aspect of our transportation infrastructure, whose performance is greatly affected by the characteristics of the spray from their injectors. Characterization of the injector’s spray is therefore tantamount to clean-running efficient diesel motors. In this study, a ~15 ps pulsed Leopard D-10 laser is used along with an optical Kerr Cell to realize ballistic images of high-delivery-pressure dodecane sprays injected into a quiescent air environment at elevated temperature and pressure. Using CS2 as the Kerr switching media and by optimizing the overlap of the gate and imaging beams, an effective high speed shuttering effect is obtained. …

Unpacking The Privacy Paradox: Irrational Decision-Making Within The Privacy Calculus, David W. Wilson, Joseph S. Valacich Jan 2012

Unpacking The Privacy Paradox: Irrational Decision-Making Within The Privacy Calculus, David W. Wilson, Joseph S. Valacich

Faculty Publications

Understanding privacy is important to individuals and organizations. This research in progress develops a theoretical model that incorporates both actual disclosure behavior and the potential for irrational behavior induced by overriding situational factors presented at the time of the privacy disclosure decision. Actual disclosure behavior is seldom measured in privacy research, and most prior work has assumed the disclosure decision to be a fully rational one. This research challenges that assumption, and the eventual completion of the project will contribute uniquely to our understanding of the privacy calculus in online transactions.

Using Tpack As A Framework To Understand Teacher Candidates’ Technology Integration Decisions, Charles R. Graham, J. Borup, N. B. Smith Jan 2012

Using Tpack As A Framework To Understand Teacher Candidates’ Technology Integration Decisions, Charles R. Graham, J. Borup, N. B. Smith

Faculty Publications

This research uses the technological pedagogical and content knowledge (TPACK) framework as a lens for understanding howteacher candidates make decisions about the use of information and communication technology in their teaching. Pre- and post-treatment assessments required elementary teacher candidates at Brigham Young University to articulate how and why they would integrate technology in three content teaching design tasks. Researchers identified themes from student rationales that mapped to the TPACK constructs. Rationales simultaneously supported subcategories of knowledge that could be helpful to other researchers trying to understand and measure TPACK. The research showed significant student growth in the use of rationales …

Strategy Selection, Surrogation, And Strategic Performance Measurement Systems, Jongwoon Choi, Gary Hecht, William B. Tayler Jan 2012

Strategy Selection, Surrogation, And Strategic Performance Measurement Systems, Jongwoon Choi, Gary Hecht, William B. Tayler

Faculty Publications

Strategic performance measurement systems operationalize firm strategy with a set of performance measures. A consequence of such alignment is the tendency for managers to lose sight of the strategic construct(s) the measures are intended to represent, and subsequently act as though the measures are the constructs of interest, a phenomenon referred to as surrogation. We investigate how involvement in strategy selection affects managers’ propensity to exhibit surrogation. We predict and find that strategy selection reduces surrogation. Surprisingly, we do not find that engaging in strategy deliberation, a key process underlying strategy selection, reduces surrogation. Thus, managers’ involvement in the actual …

A Proposal For A Feasible, First-Step, Legislative Agenda For Divorce Reform, Alan J. Hawkins Jan 2012

A Proposal For A Feasible, First-Step, Legislative Agenda For Divorce Reform, Alan J. Hawkins

Faculty Publications

American sociologist Andrew Cherlin argues that the institutional boundaries of marriage have shrunk; marriage no longer effectively governs intimate associations before marriage, or structures "proper" pathways to the desired goal of healthy, stable marriage. Personal development and individual emotions are at the core of modern marriage, rather than societal expectations and religious and civil norms. Accordingly, marriages are held together now by internal, psychological forces rather than external, societal forces, and these bonds are substantially weaker. As a result, divorce is common, with about half ending within twenty years; second marriages have even higher rates of disruption. While the divorce …

Antecedents Of Identity Development In A Structured Recreation Setting: A Qualitative Inquiry, Mat D. Duerden, Stacy Taniguchi, Mark Widmer

Faculty Publications

Identity research has focused primarily on outcomes associated with identity formation. Far less attention, however, has been given to understanding the facilitating contextual elements of this process. This qualitative study examined a context, a 2-week adventure recreation program for youth, quantitatively shown in previous research to have promoted identity development. The program took place in Idaho’s Salmon-Challis National Forest and involved rafting, backpacking, mountain biking, and a variety of other outdoor activities. Data were gathered from 23 female and 22 male participants, ages 11 to 15 (M = 13.2, SD = .89). Seven distinct categories emerged from the analysis related …

Using An Elaboration Likelihood Approach To Better Understand The Persuasiveness Of Website Privacy Assurance Cues For Online Consumers, Paul Benjamin Lowry, Gregory D. Moody, Anthony Vance, Matthew Jensen, Jeffrey L. Jenkins, Taylor Michael Wells Jan 2012

Using An Elaboration Likelihood Approach To Better Understand The Persuasiveness Of Website Privacy Assurance Cues For Online Consumers, Paul Benjamin Lowry, Gregory D. Moody, Anthony Vance, Matthew Jensen, Jeffrey L. Jenkins, Taylor Michael Wells

Faculty Publications

Privacy concerns can greatly hinder consumers’ intentions to interact with a website. The success of a website therefore depends on its ability to improve consumers’ perceptions of privacy assurance. Seals and assurance statements are mechanisms often used to increase this assurance; however, the findings of the extant literature regarding the effectiveness of these tools are mixed. We propose a model based on the elaboration likelihood model (ELM) that explains conditions under which privacy assurance is more or less effective, clarifying the contradictory findings in previous literature. We test our model in a free-simulation online experiment, and the results of the …
