Measurement of the inclusive νμ charged current cross section on iron and hydrocarbon in the T2K on-axis neutrino beam

Abstract: We report a measurement of the nu(mu) inclusive charged current cross sections on iron and hydrocarbon in the Tokai-to-Kamioka (T2K) on-axis neutrino beam. The measured inclusive charged current cross sections on iron and hydrocarbon averaged over the T2K on-axis flux with a mean neutrino energy of 1.51 GeVare (1.444 +/- 0.002(stat)(-0.157)(+0.189)- (syst)) x 10(-38) cm(2)/ nucleon and (1.379 +/- 0.009(stat)(-0.147)(+0.178) (syst)) x 10(-38) 38 cm(2)/ nucleon, respectively, and their cross-section ratio is 1.047 +/- 0.007(stat) +/- 0.035(syst). These results agree well with the predictions of the neutrino interaction model, and thus we checked the correct treatment of the nuclear effect for iron and hydrocarbon targets in the model within the measurement precisions.

Gaps between beliefs, perceptions, and practices: The Every Teacher Project on LGBTQ-inclusive education in Canadian schools

Abstract: The Every Teacher Project involved large-scale survey research conducted to identify the beliefs, perspectives, and practices of Kindergarten to Grade 12 educators in Canadian public schools regarding lesbian, gay, bisexual, transgender, and queer (LGBTQ)–inclusive education. Comparisons are made between LGBTQ and cisgender heterosexual participants, between participants teaching at different grade levels, and between participants in school districts with and without antihomophobia and antitransphobia harassment policies. The authors present an analysis of the findings framed in terms of problematic gaps between educators' beliefs, perceptions, and practices. These gaps are considered in light of emerging best practices in LGBTQ-inclusive education that have been developed to improve school climates for all students, and especially for sexual and gender minority students, students with sexual and gender minority parents and other loved ones, and indeed any students who are negatively affected by h...

Reflectance spectra of iron meteorites: Implications for spectral identification of their parent bodies

Abstract: – The 0.35–2.5 μm reflectance spectra of iron meteorite powders and slabs have been studied as a function of composition, surface texture (for slabs), grain size (for powders), and viewing geometry (for powders). Powder spectra are invariably red-sloped over this wavelength interval and have a narrow range of visible albedos (approximately 10–15% at 0.56 μm). Metal (Fe:Ni) compositional variations have no systematic effect on the powder spectra, increasing grain size results in more red-sloped spectra, and changes in viewing geometry have variable effects on overall reflectance and spectral slope. Roughened metal slab spectra have a wider, and higher, range of visible albedos than powders (22–74% at 0.56 μm), and are also red-sloped. Smoother slabs exhibit greater differences from iron meteorite powder spectra, exhibiting wider variations in overall reflectance, spectral slopes, and spectral shapes. No unique spectral parameters exist that allow for powder and slab spectra to be fully separated in all cases. Spectral differences between slabs and powders can be used to constrain possible surface properties, and causes of rotational spectral variations, of M-asteroids. The magnitude of spectral variations between M-asteroids and rotational and spectral variability does not necessarily imply a dramatic change in surface properties, as the differences in albedo and/or spectral slope can be accommodated by modest changes in grain size (for powders), small changes in surface roughness (for slabs), or variations in viewing geometry. Since metal powders exhibit much less spectral variability than slabs, M-asteroid spectral variability requires larger changes in either powder properties or viewing geometry than for slabs for a given degree of spectral variation.

Evaluation of a Youth-Led Program for Preventing Bullying, Sexual Harassment, and Dating Aggression in Middle Schools.

Abstract: Although youth-led programs (YLP) have been successful in many areas of public health, youth leadership is rarely used in the prevention of peer aggression. A YLP to reduce bullying, sexual harassm...
