A Consistent Spectral Model of WR 136 and its Associated Bubble NGC 6888
, 2015 We analyse whether a stellar atmosphere model computed with the code CMFGEN provides an optimal description of the stellar observations of WR 136 and simultaneously reproduces the nebular observations of NGC 6888, such as the ionization degree, which is ...

Decisions Under Radical Uncertainty: The Role of Volitional Liminality in Radical Innovation
Journal of Product Innovation Management, EarlyView.ABSTRACT Academic Summary Radical innovation management can be understood as an organizational practice that enacts distant futures, which are open‐ended and unknowable. Such radical innovation endeavors are thus characterized by radical uncertainty, where possible futures are not only quantitatively but qualitatively different from the present, and ...

Nonparametric Detection of a Time‐Varying Mean
Journal of Time Series Analysis, EarlyView.ABSTRACT We propose a nonparametric portmanteau test for detecting changes in the unconditional mean of a univariate time series which may display either long or short memory. Our approach is designed to have power against, among other things, cases where the mean component of the series displays abrupt level shifts, deterministic trending behaviour ...

Oracy for civic voice: Deconstructing practice through classroom vignettes
Literacy, EarlyView.Abstract The importance of spoken language in education for curricular, pedagogical and societal purposes is well established and sometimes articulated as oracy education. This article draws on Shulman's work on learning from cases to explore critically the use of oracy to promote civic values and voice. Realising the ideals of deliberative dialogue in

Chondrule Survivability in the Solar Nebula
The Astrophysical JournalThe lifetime of millimeter-sized dust grains, such as chondrules, in the nominal solar nebula model is limited to ∼10 ^5 yr, due to an inward drift driven by gas drag.

Petrography of phosphates in CI and CY carbonaceous chondrites
Meteoritics &Planetary Science, EarlyView.Abstract Phosphate minerals are significant carriers of volatiles (e.g., OH) and halogens in chondritic material; however, their origin in most groups of carbonaceous chondrites remains poorly characterized. We have determined the abundance, morphology, texture, and composition of phosphate grains in aqueously altered CI chondrites and in hydrated and ...

Planetary nebulae : getting closer to an unbiased binary fraction
, 2012 Why 80% of planetary nebulae are not spherical is not yet understood. The Binary Hypothesis states that a companion to the progenitor of the central star of a planetary nebula is required to shape the nebula and even for a planetary nebula to be formed ...
