The Bazaar as a Model for Knowledge Work
ABSTRACT This paper presents fieldwork that extends existing metaphors of knowledge work as a process shaped by hierarchical or market forces. A qualitative, ethnographic study of six knowledge‐intensive businesses in two countries identifies striking parallels with the Middle Eastern bazaar in contrast to Western impersonal markets and hierarchies.

Irradiation-driven Formation of Supersoft X-Ray Sources following Classical Novae
Supersoft X-ray sources (SSSs) are characterized by persistent thermonuclear burning on the surfaces of white dwarfs (WDs). The standard model requires high mass-transfer rates of ∼10 ^−7 M _⊙ yr ^−1 from massive companions, presenting a theoretical ...

Recent progress in understanding the eruptions of classical novae [PDF]
Dramatic progress has occurred in the last two decades in understanding the physical processes and events leading up to, and transpiring during the eruption of a classical nova.

Recurrent Novae, Classical Novae, Symbiotic Novae, and Population II Novae
Light curve analysis of decay phase of nova outburst are summarized. Nova duration is determined by the strong wind mass-loss which depends only on the white dwarf mass. Fast novae correspond very massive white dwarfs and very slow novae correspond almost lower mass limit of white dwarfs.

Abstract Particles sinking from the surface to the deep ocean play a key role in the biological carbon pump, whose efficiency depends partly on sinking velocities. Over the last decade, in situ imaging has enabled critical advances in our understanding of particle dynamics in the ocean.

Upper Bound of Ejecta Mass in a Nova Outburst
We present the maximum ejecta mass ${({M}_{{\rm{ej}}})}_{{\rm{\max }}}$ and the maximum ratio of ejecta mass and accreted mass ${({M}_{{\rm{ej}}}/{M}_{{\rm{acc}}})}_{{\rm{\max }}}$ of a nova for various white dwarf (WD) masses ( M _WD = 0.6–1.38 M _ ...

A Severity‐Agnostic Atrophy Pattern in Spinocerebellar Ataxia Type 3: Volumetrics from ENIGMA‐Ataxia
Background Spinocerebellar ataxia type 3 (SCA3) is a rare, inherited neurodegenerative disease characterized by progressive loss of motor coordination. Objectives We undertook a multisite magnetic resonance imaging study to profile the spatial spread of atrophy across the brain, determine whether atrophy preferentially maps onto specific functional ...

Exploring Asymptotic Normality in Multinomial Models
ABSTRACT Among the methods for analyzing categorical outcomes, the multinomial model offers a robust framework for examining the dependence between a multi‐category response variable and a set of explanatory variables. Its flexibility, versatility, and broad applicability across diverse fields make it a valuable tool, as it does not impose strict ...
