Embedding Aboriginal and Torres Strait Islander LGBTIQ+ issues in primary initial teacher education programs

Existing research has explored inclusion in education, however, issues related to Aboriginal and Torres Strait Islander LGBTIQ+ young people, with some notable exceptions, have, until recently, seldom been included in any meaningful academic discussion. Issues of youth race, gender and sexuality have been interrogated as discrete issues. This small but growing body of research demonstrates the potential impacts of intersectional disadvantages experienced by Aboriginal and Torres Strait Islander LGBTIQ+ young people in Australia (Uink, Liddelow-Hunt, Daglas, & Ducasse, 2020). This article seeks to explore the existing research and advocate for the embedding of a critical pedagogy of care in primary Initial Teacher Education (ITE) curricula, inclusive of diversity of race, ethnicity, socio-economic-status, gender and sexuality. Employing intersectionality theory, this research will examine the specific disadvantages that arise as the result of occupying multiple minority demographic categories, which are relational, complex and shifting, rather than fixed and independent. Primary educators are well positioned to name disadvantage, racism and heterosexism, make them visible and, through culturally responsive pedagogical approaches and inclusive curricula, challenge the status quo. To ensure that learning and teaching moves beyond stereotypes, primary curricula should be representative of all students and present alternate ways of being human in culturally appropriate, positive ways, to the benefit of all students. ITE programs provide the ideal arena to equip teachers with the knowledge and competency to respond to the needs of Aboriginal and Torres Strait Islander LGBTIQ+ young people

Oxygen and Carbon Isotopes in Modern and Historic Mussels from the Snake River, Idaho, May Show Modern Rise of Corn Production

Stable carbon and oxygen isotope compositions were analyzed from local mussels ranging in age from 0 to 1000 years before the present to identify any trends and seasonal variability in the oxygen and carbon (18O and 13C values), compare trends and averages in 18O and 13C across different time periods and species of mussel, and finally use 18O to gain insight into how climate conditions might have changed in the past 1000 years. The Western Ridged Mussel (Gonidea angulate) and Western Pearlshell Mussel (Margaritifera falcata) are two species of freshwater mussels found in the Snake River in southern Idaho. Both species seasonally produce a calcium carbonate shell outward as they age. Previous research has shown mussels typically form their shells in isotopic equilibrium with the surrounding water and therefore can be a reliable indicator of environmental conditions such as temperature and seasonality. Outer growth bands were sampled sequentially from mussels dated ~1200 years before present, as well as from modern shells. The powdered samples were analyzed using an isotope ratio mass spectrometer in the Department of Geosciences, Boise State University, to obtain δ18O and δ13C values. Modern shells were found to have an average δ18O value of -16.6‰ (VPDB) and an average δ13C value of -8.8‰ (VPDB). δ18O was nearly constant across the shell, but δ13C increased as the mussel grew. Historic shells had homogeneous δ18O values of -16.4‰ and homogeneous δ13C values of -11.6‰. δ18O values of the two time periods are very similar, suggesting no resolvable changes to climatic conditions using this proxy. Increased δ13C values in modern mussels relative to historic mussels suggest a potentially significant increase of C4 plant contribution to the Snake River. We interpret this enrichment to be due to modern production of corn (a C4 plant) along the Snake River, especially since ~2000 CE

Fast, low-artifact speech synthesis considering global variance

Copyright 2013 IEEE.Speech parameter generation considering global variance (GV generation) is widely acknowledged to dramatically improve the quality of synthetic speech generated by HMM-based systems. However it is slower and has higher latency than the standard speech parameter generation algorithm. In addition it is known to produce artifacts, though existing approaches to prevent artifacts are effective. We present a simple new theoretical analysis of speech parameter generation considering global variance based on Lagrange multipliers. This analysis sheds light on one source of artifacts and suggests a way to reduce their occurrence. It also suggests an approximation to exact GV generation that allows fast, low latency synthesis. In a subjective evaluation our fast approximation shows no degradation in naturalness compared to conventional GV generation.This work was supported in part by EPSRC Programme Grant EP/I031022/1 (Natural Speech Technology)

Comparison of Salmonella enterica Serovars Typhi and Typhimurium Reveals Typhoidal Serovar-Specific Responses to Bile.

Salmonella enterica serovars Typhi and Typhimurium cause typhoid fever and gastroenteritis, respectively. A unique feature of typhoid infection is asymptomatic carriage within the gallbladder, which is linked with S Typhi transmission. Despite this, S Typhi responses to bile have been poorly studied. Transcriptome sequencing (RNA-Seq) of S Typhi Ty2 and a clinical S Typhi isolate belonging to the globally dominant H58 lineage (strain 129-0238), as well as S Typhimurium 14028, revealed that 249, 389, and 453 genes, respectively, were differentially expressed in the presence of 3% bile compared to control cultures lacking bile. fad genes, the actP-acs operon, and putative sialic acid uptake and metabolism genes (t1787 to t1790) were upregulated in all strains following bile exposure, which may represent adaptation to the small intestine environment. Genes within the Salmonella pathogenicity island 1 (SPI-1), those encoding a type IIII secretion system (T3SS), and motility genes were significantly upregulated in both S Typhi strains in bile but downregulated in S Typhimurium. Western blots of the SPI-1 proteins SipC, SipD, SopB, and SopE validated the gene expression data. Consistent with this, bile significantly increased S Typhi HeLa cell invasion, while S Typhimurium invasion was significantly repressed. Protein stability assays demonstrated that in S Typhi the half-life of HilD, the dominant regulator of SPI-1, is three times longer in the presence of bile; this increase in stability was independent of the acetyltransferase Pat. Overall, we found that S Typhi exhibits a specific response to bile, especially with regard to virulence gene expression, which could impact pathogenesis and transmission

On the Effect of Magnetic Spots on Stellar Winds and Angular Momentum Loss

We simulate the effect of latitudinal variations in the location of star spots, as well as their magnetic field strength, on stellar angular momentum loss to the stellar wind. We use the Michigan solar corona global MagnetoHydroDynamic model, which incorporates realistic relation between the magnetic field topology and the wind distribution. We find that the spots location significantly affects the stellar wind structure, and as a result, the total mass loss rate and angular momentum loss rate. In particular, we find that the angular momentum loss rate is controlled by the mass flux when spots are located at low latitudes but is controlled by an increased plasma density between the stellar surface and the Alfven surface when spots are located at high latitudes. Our results suggest that there might be a feedback mechanism between the magnetic field distribution, wind distribution, angular momentum loss through the wind, and the motions at the convection zone that generate the magnetic field. This feedback might explain the role of coronal magnetic fields in stellar dynamos
