Double the Vocation, Double the Awe: An Examination of Vocational Awe in Music Librarianship

Building upon Ettarh’s call to dismantle vocational awe in librarianship, this article outlines the shared components of Western libraries and Western music that lay the groundwork for vocational awe in each of these institutions and explores the ways in which vocational awe uniquely manifests for workers in the interdisciplinary field of music librarianship. The article explores the narrative of music’s goodness, disciplinary training, and manifestations of vocational awe as they appear in the institutional cultures of practice of music and librarianship: inability to develop work-life balance, job creep, low morale, and inequitable compensation. In naming this phenomenon as it is situated within music and music librarianship, we critically examine how it may affect our own narratives and values. We seek to empower those in music library work to become mindful of and address the presence and influence of vocational awe at individual and institutional levels

Cooking quality, digestibility, and sensory properties of proso millet pasta as impacted by amylose content and prolamin profile

As part of ongoing e\ufb00orts to promote millet as a double crop for the American Midwest, four Minnesota-grownproso millet varieties were selected for fresh gluten-free pasta production and compared to commerciallyavailable fresh gluten-free and wheat pasta. Raw and cooked pasta were analyzed for starch and protein content,color, and carotenoids. Cooked pasta was assessed for cooking quality, in-vitro starch and protein digestibility,and sensory quality. Millet pasta contained less rapidly digestible starch than commercial gluten-free pasta;however, millet and commercial gluten-free pasta had lower protein digestibility than wheat pasta. Sensorypanelists detected more graininess and starchiness in millet samples than in commercial pasta. Millet varietiesdi\ufb00ered in amylose content and prolamin pro\ufb01le, and both factors in\ufb02uenced pasta properties. Pasta with moreamylose and high-molecular weight prolamins had lower cooking loss and lower stickiness scores. Higheramylose contents also corresponded to higher \ufb01rmness and chewiness among millet pasta samples. The milletsample with the lowest amylose and prolamin content yielded pasta of the lowest quality. Results indicated thatselect proso millet varieties may be suitable for fresh pasta, yet quality improvement is warranted by recipe orprocessing optimizations

Change the Tempo: Dismantling Vocational Awe in Music Librarianship

Interactive session. Vocational awe as identified by Fobazi Ettarh refers to the, “set of ideas, values, and assumptions librarians have about themselves and the profession that result in beliefs that libraries as institutions are inherently good and sacred, and therefore beyond critique.” As a profession, librarianship is often considered as more than “just a job,” but a calling to service grounded in noble values related to education, intellectual freedom, and democracy. While this characterization celebrates librarianship as rewarding and meaningful work, it also fosters a culture of martyrdom, inhibits critical examination of the profession, and inadvertently promotes a spirit of elitism and judgment. Ultimately, such characteristics are incompatible with the ostensible values held by professionals within music librarianship. It is Ettarh’s dedicated, fearless work of challenging the profound notion of vocational awe that has laid the foundation to begin the work of unpacking this concept within the profession of music librarianship. This interactive session provides participants with the opportunity to discuss, and examine the praxis of dismantling vocational awe and the notion that the profession of music librarianship is beyond critique. Panelist will lead group discussions to explore how the worlds of music and librarianship reinforce the manifestations of vocational awe in each other and critically examine the potential impact in areas such as advocacy for music libraries and library workers, as well as the effort to create an equitable and inclusive profession

Structural properties of thin-film ferromagnetic topological insulators

We present a comprehensive study of the crystal structure of the thin-film, ferromagnetic topological insulator (Bi, Sb)2 xVxTe3 .The dissipationless quantum anomalous Hall edge states it manifests are of particular interest for spintronics, as a natural spin filter or pure spin source, and as qubits for topological quantum computing. For ranges typically used in experiments, we investigate the effect of doping, substrate choice and film thickness on the (Bi, Sb)2Te3 unit cell using high-resolution X-ray diffractometry. Scanning transmission electron microscopy and energy-dispersive X-ray spectroscopy measurements provide local structural and interfacial information. We find that the unit cell is unaffected in-plane by vanadium doping changes, and remains unchanged over a thickness range of 4–10 quintuple layers (1 QL 1 nm). The in-plane lattice parameter (a) also remains the same in films grown on different substrate materials. However, out-of-plane the c-axis increases with the doping level and thicknesses >10 QL, and is potentially reduced in films grown on Si (1 1 1).This work was financially supported by the Leverhulme Trust (RPG-2013-337), the European Commission through a Marie Curie Grant (MSCA-IFEF-ST No. 656485-Spin3), the Royal Society, and the Engineering and Physical Sciences Research Council (EP/P026311/1).C.-Z.C. and J.S.M. acknowledge support from from the NSF (DMR-1207469, DMR-1700137), ONR (N00014-13-1-0301, N00014-16-1-2657), and the STC Center for Integrated Quantum Materials under NSF grant DMR-1231319

The Efficiency of Gravitational Bremsstrahlung Production in the Collision of Two Schwarzschild Black Holes

We examine the efficiency of gravitational bremsstrahlung production in the process of head-on collision of two boosted Schwarzschild black holes. We constructed initial data for the characteristic initial value problem in Robinson-Trautman spacetimes, that represent two instantaneously stationary Schwarzschild black holes in motion towards each other with the same velocity. The Robinson-Trautman equation was integrated for these initial data using a numerical code based on the Galerkin method. The final resulting configuration is a boosted black hole with Bondi mass greater than the sum of the individual mass of each initial black hole. Two relevant aspects of the process are presented. The first relates the efficiency $\Delta$ of the energy extraction by gravitational wave emission to the mass of the final black hole. This relation is fitted by a distribution function of non-extensive thermostatistics with entropic parameter $q \simeq 1/2$; the result extends and validates analysis based on the linearized theory of gravitational wave emission. The second is a typical bremsstrahlung angular pattern in the early period of emission at the wave zone, a consequence of the deceleration of the black holes as they coalesce; this pattern evolves to a quadrupole form for later times.Comment: 16 pages, 4 figures, to appear in Int.

Information completeness in Nelson algebras of rough sets induced by quasiorders

In this paper, we give an algebraic completeness theorem for constructive logic with strong negation in terms of finite rough set-based Nelson algebras determined by quasiorders. We show how for a quasiorder $R$, its rough set-based Nelson algebra can be obtained by applying the well-known construction by Sendlewski. We prove that if the set of all $R$-closed elements, which may be viewed as the set of completely defined objects, is cofinal, then the rough set-based Nelson algebra determined by a quasiorder forms an effective lattice, that is, an algebraic model of the logic $E_0$, which is characterised by a modal operator grasping the notion of "to be classically valid". We present a necessary and sufficient condition under which a Nelson algebra is isomorphic to a rough set-based effective lattice determined by a quasiorder.Comment: 15 page

Gene expression profiling in the Cynomolgus macaque Macaca fascicularis shows variation within the normal birth range

BACKGROUND: Although an adverse early-life environment has been linked to an increased risk of developing the metabolic syndrome, the molecular mechanisms underlying altered disease susceptibility as well as their relevance to humans are largely unknown. Importantly, emerging evidence suggests that these effects operate within the normal range of birth weights and involve mechanisms of developmental palsticity rather than pathology. METHOD: To explore this further, we utilised a non-human primate model Macaca fascicularis (Cynomolgus macaque) which shares with humans the same progressive history of the metabolic syndrome. Using microarray we compared tissues from neonates in the average birth weight (50-75(th )centile) to those of lower birth weight (5-25(th )centile) and studied the effect of different growth trajectories within the normal range on gene expression levels in the umbilical cord, neonatal liver and skeletal muscle. RESULTS: We identified 1973 genes which were differentially expressed in the three tissue types between average and low birth weight animals (P < 0.05). Gene ontology analysis identified that these genes were involved in metabolic processes including cellular lipid metabolism, cellular biosynthesis, cellular macromolecule synthesis, cellular nitrogen metabolism, cellular carbohydrate metabolism, cellular catabolism, nucleotide and nucleic acid metabolism, regulation of molecular functions, biological adhesion and development. CONCLUSION: These differences in gene expression levels between animals in the upper and lower percentiles of the normal birth weight range may point towards early life metabolic adaptations that in later life result in differences in disease risk

Central obesity as a precursor to the metabolic syndrome in the AusDiab study and Mauritius

Evidence from epidemiologic studies that central obesity precedes future metabolic change and does not occur concurrently with the appearance of the blood pressure, glucose, and lipid abnormalities that characterize the metabolic syndrome (MetS) has been lacking. Longitudinal surveys were conducted in Mauritius in 1987, 1992, and 1998, and in Australia in 2000 and 2005 (AusDiab). This analysis included men and women (aged 25 years) in three cohorts: AusDiab 2000&ndash;2005 (n = 5,039), Mauritius 1987&ndash;1992 (n = 2,849), and Mauritius 1987&ndash;1998 (n = 1,999). MetS components included waist circumference, systolic blood pressure, fasting and 2-h postload plasma glucose, high-density lipoprotein (HDL) cholesterol, triglycerides, and homeostasis model assessment of insulin sensitivity (HOMA-S) (representing insulin sensitivity). Linear regression was used to determine which baseline components predicted deterioration in other MetS components over 5 years in AusDiab and 5 and 11 years in Mauritius, adjusted for age, sex, and ethnic group. Baseline waist circumference predicted deterioration (P &lt; 0.01) in four of the other six MetS variables tested in AusDiab, five of six in Mauritius 1987&ndash;1992, and four of six in Mauritius 1987&ndash;1998. In contrast, an increase in waist circumference between baseline and follow-up was only predicted by insulin sensitivity (HOMA-S) at baseline, and only in one of the three cohorts. These results suggest that central obesity plays a central role in the development of the MetS and appears to precede the appearance of the other MetS components.<br /
