Communication: On the stability of ice 0, ice i, and I(h)
No full textUsing ab initio methods, we examine the stability of ice 0, a recently proposed tetragonal form of ice implicated in the homogeneous freezing of water [J. Russo, F. Romano, and H. Tanaka, Nat. Mater. 13, 670 (2014)]. Vibrational frequencies are computed across the complete Brillouin Zone using Density Functional Theory (DFT), to confirm mechanical stability and quantify the free energy of ice 0 relative to ice I(h). The robustness of this result is tested via dispersion corrected semi-local and hybrid DFT, and Quantum Monte-Carlo calculation of lattice energies. Results indicate that popular molecular models only slightly overestimate the stability of ice zero. In addition, we study all possible realisations of proton disorder within the ice zero unit cell, and identify the ground state as ferroelectric. Comparisons are made to other low density metastable forms of ice, suggesting that the ice i structure [C. J. Fennel and J. D. Gezelter, J. Chem. Theory Comput. 1, 662 (2005)] may be equally relevant to ice formation
"Let Them Speak their Peace": A Retrospective Critical Race Exploration of Adolescent Black Male Social and Schooling Experiences, Identity Development, and Educational/Life Outcomes in Pittsburgh
No full textHow adolescent black males make meaning of their social and schooling experiences affects the development of identities that can serve as risk-factors for acedemic engagement, achievement, and life outcome. Although research on racial and ethnic identity among youth of color has flourished during the last two decades, little of that research has directly examined the relationship between identity, achievement, and life trajectory. There has been no research examining these relationships specifically in Pittsburgh, a city with historically deep racial educational and economic disparities. In order to better understand how identity influences academic engagement, educational outcomes, social choices, and life trajectories in Pitsburgh specifically and the U.S. more broadly, in-depth phenomenological interviews were conducted from a sample of 10 black men who attended Pittsburgh Public Schools. This exploratory study used the retrospective recollections of these men to examine the social and schooling experiences of adolescent black males in this context. Three respondents were selected from this sample and their respective interview data were crafted into narrative profiles. Critical race theory (CRT) was the primary paradigmatic lens through which these experiences were examined and the interview data analyzed and reported on.
Findings showed four salient themes of respect, internalized racism, the power in words and names, and the CRT construct whiteness as property at work in their adolescent experiences.
Two meta-themes of multiple interpretations of black masculinity, achievement, and race, and differend cut across all of the narratives. In a researcher reflection on the power of voice, the counter-story telling construct of CRT is discussed, revealing the positive affect and healing capacity it holds for black males. This discussion is a defense for maintaining the differend and is situated within an argument for the utility of CRT as an appropriate methodological and analytical tool to examine and disrupt the pervasive academic struggles of black males. Implications for the schooling of black males; why it is important to listen to what black men have to say about their schooling; new possibilities for educational policy and practice; and new ontological possibilites and ethical responsibilities for adults in schools are discussed as well
Oil impregnated sandstone study near Bruin Point and Range Creek--Sunnyside Quadrangle
No full textreportAn investigation into the oil sandstones in the Book Cliffs area northest of Sunnyside, Utah, showed an eastward continuation of the oil impregnated sandstones (oiss) previously mapped (USGS, OM 86, 1948). The survey was conducted from June 19 through 21, 1972 by Sam Quigley and D. Craig Mann. The area mapped is found at the headwaters of Range Creek (T14S, R14E) and Dry Creek (T13S, R14E) in Carbon County. The oiss in the area occures in the Lower Green River
Confidence intervals for reliability growth models with small sample sizes
No full textFully Bayesian approaches to analysis can be overly ambitious where there exist realistic limitations on the ability of experts to provide prior distributions for all relevant parameters. This research was motivated by situations where expert judgement exists to support the development of prior distributions describing the number of faults potentially inherent within a design but could not support useful descriptions of the rate at which they would be detected during a reliability-growth test. This paper develops inference properties for a reliability-growth model. The approach assumes a prior distribution for the ultimate number of faults that would be exposed if testing were to continue ad infinitum, but estimates the parameters of the intensity function empirically. A fixed-point iteration procedure to obtain the maximum likelihood estimate is investigated for bias and conditions of existence. The main purpose of this model is to support inference in situations where failure data are few. A procedure for providing statistical confidence intervals is investigated and shown to be suitable for small sample sizes. An application of these techniques is illustrated by an example

Striving to Persist: Museum Digital Exhibition and Digital Catalogue Production
No full textAlthough museum automation emerged in the mid-1960s, American and British art museums continue to have a difficult relationship with digital technology. Indeed, within the broader cultural heritage network, art museums have been particularly reluctant to disseminate their missions online. Particularly since the eighteenth century, art museums have remained beholden to certain perceptions of authority that are tied to the authentic object. Yet, as new technologies offer more efficient and cost-effective ways to store and disseminate information
and promise greater accessibility, these museums have continued in their efforts to incorporate digital methods into their practices.
The following document considers the role of information organization in the creation of knowledge and value within and beyond the space of the art museum by interrogating two major scholarly products of the well-endowed, early 21st century Western art museum’s ecosystem:
online catalogues and online exhibitions. Given their contexts, the questions sustaining this research converge at the junction of three major areas: the new museology movement, exhibition culture, and museum computing. Public-facing, museum-based digital scholarship practices have emerged fairly recently (mostly from the mid-1990s onwards). The impact of these practices within the space of the art museum has not yet received a critical treatment, so the costs and
benefits of this new mode of interpretation and production remain a mystery.
In this study, the author first defines physical exhibitions and catalogues to contextualize their digital counterparts, and building on this, examines two sites in depth using a case study approach. Although The Gallery of Lost Art and On Performativity are inherently different in that one represents an online exhibition and the other an online catalogue, they shared overlapping lifespans and emerged in similar technological and museological landscapes. They also documented ephemeral artworks. The data collected throughout demonstrates the significance of socio-technical infrastructures and project management approaches, and how museums have struggled to adapt these practices to produce new information outputs. Museum
computing seems to remain “disruptive” in 2019. Rather than revolutionizing through decentralization or democratization, computing seems to disrupt the mechanisms occurring behind the scenes in an art museum
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
"enchanted days" for chamber ensemble: Some Considerations and Analysis
No full textenchanted days, for flute, clarinet, violin, cello, piano and percussion represents the largest and stylistically most advanced composition of mine to date. The piece centers on the fulfillment and denial of perfect consonances (the octave and unison), in such a way that the various instrument pairings and doublings develop dramatic characters, and eventually create their own "rules" that describe the context for the uses of consonance and dissonance. These rules—centered around the three concepts of unity, unexpectedness, and drama—create transformations of the two large categories of material, which can be roughly described as triadic harmonies with "wrong notes" added, contrasted with tone clusters relating to Major and minor seconds. A sense of humor enters the piece as part of these transformations; however, by the end, not only have the roles of various instruments changed, they have been compromised almost to reversal—a compromise that is somber and resigned. This reversal applies not only to the instrumental "characters", but to the relationship between D and C#, the crucial notes of the work
