Organizational Behaviour : 360 Series
(Routledge, 2012) -
An organizational study into the concept of automation in a safety critical socio-technical system
(Springer Nature, 2013) -
An organizational study into the concept of “automation policy” in a safety critical socio-technical system.
(2013)Although automation has been introduced in all areas of public life, what seems to be missing is a reflection at the organizational or societal level about a policy of automation. By this we intend appropriate declarations ... -
Organizing for thoughtful food: A meshwork approach
(2020-08-08)This paper provides an alternative narrative for organizing food systems. It introduces meshwork as a novel theoretical lens to examine the ontological assumptions underlying the shadow and informal dynamics of organizing ... -
An orientation bias in observations of submillimetre galaxies
(2022-07-28)Recent high-resolution interferometric images of submillimetre galaxies (SMGs) reveal fascinatingly complex morphologies. This raises a number of questions: how does the relative orientation of a galaxy affect its observed ... -
Orientation effects in quasar spectra: the broad- and narrow-line regions
(2011-03)We use the Sloan Digital Sky Survey, along with the NRAO VLA Sky Survey and the Westerbork Northern Sky Survey to define a sample of 746 radio-loud quasars and measure their 330 MHz-1.4 GHz spectral indexes. Following ... -
Origin of color gradients in elliptical galaxies
(2000-05)The origin of color gradients in elliptical galaxies is examined by comparing model gradients with those observed in the Hubble Deep Field. The models are constructed so as to reproduce color gradients in local elliptical ... -
The Origin of Elements from Carbon to Uranium
(2020-09-15)To reach a deeper understanding of the origin of elements in the periodic table, we construct Galactic chemical evolution (GCE) models for all stable elements from C (A = 12) to U (A = 238) from first principles, i.e., ... -
The origin of elements: the need for UV spectra
(2022-07-23)Thanks to the long-term collaborations between nuclear and astrophysics, we have good understanding on stellar nucleosynthesis, except for the elements around Ti and some neutron-capture elements. From the comparison between ... -
The origin of elliptical galaxies inferred from their metallicity gradients
(2003-04)We simulate the chemodynamical evolution of elliptical galaxies using our GRAPE-SPH code. We succeed in reproducing the observed variety of the radial metallicity gradients, from which we discuss the origin of elliptical galaxies. -
The Origin of Helium-Rich Subdwarf O Stars
(Astronomical Society of the Pacific, 2008)The origin of helium-rich subdwarf O stars (He-sdO) is still unclear. Significant progress has been made recently in placing them in the Hertzsprung–Russell diagram. However, the question of their progenitors is still ... -
The Origin of High-energy Emission in the Young Radio Source PKS 1718–649
(2022-12-12)We present a model for the broadband radio-to-γ-ray spectral energy distribution of the compact radio source PKS 1718 − 649. Because of its young age (≃100 yr) and proximity (z = 0.014), PKS 1718 − 649 offers a unique ... -
The origin of kinematically distinct cores and misaligned gas discs in galaxies from cosmological simulations
(2018-09-01)Integral field spectroscopy surveys provide spatially resolved gas and stellar kinematics of galaxies. They have unveiled a range of atypical kinematic phenomena, which require detailed modelling to understand. We present ... -
The origin of low [alpha/Fe] ratios in extremely metal-poor stars
(2014-03-25)We show that the low ratios of $\alpha$ elements (Mg, Si, and Ca) to Fe recently found for a small fraction of extremely metal-poor stars can be naturally explained with the nucleosynthesis yields of core-collapse supernovae, ... -
The origin of low-surface-brightness galaxies in the dwarf regime
(2021-01-13)Low-surface-brightness galaxies (LSBGs) -- defined as systems that are fainter than the surface-brightness limits of past wide-area surveys -- form the overwhelming majority of galaxies in the dwarf regime (M* < 10^9 MSun). ... -
Origin of metals in old Milky Way halo stars based on GALAH and Gaia
(2021-10-01)Stellar and supernova nucleosynthesis in the first few billion years of the cosmic history have set the scene for early structure formation in the Universe, while little is known about their nature. Making use of stellar ...
