Inferring the Andromeda Galaxy's mass from its giant southern stream with Bayesian simulation sampling

, 2013
M31 has a giant stream of stars extending far to the south and a great deal of other tidal debris in its halo, much of which is thought to be directly associated with the southern stream. We model this structure by means of Bayesian sampling of parameter

Measuring and Harmonising Coverage, Generosity and History of Work‐Injury Policies Globally

Social Policy &Administration, Volume 59, Issue 7, Page 1275-1292, December 2025.
ABSTRACT I present new measures of generosity, coverage and institutional characteristics of work‐injury policy across 189 countries in the Global Work‐Injury Policy Dataset (GWIP) version 2.0. To date, major research efforts produced detailed social policy data for the rich Western countries, and more recently countries of Eastern, Central and Central‐

The Kinematics within M31 [PDF]

Symposium - International Astronomical Union, 1978
A new hydrogen line survey of M31 is described. A rotation curve of the galaxy is derived from these data. The northern half of the rotation curve can be traced to 27 kpc, the southern to 30 kpc. They are in general agreement; both sides show an extensive region of essentially constant rotational velocity.

Holding dysregulation in mind: How maternal mind‐mindedness relates to regulatory symptoms and disorders in infancy

Infant Mental Health Journal: Infancy and Early Childhood, Volume 46, Issue 6, Page 855-869, November 2025.
Abstract This study examined the role of maternal mind‐mindedness (MM) – the tendency to ascribe mental states to one's child – in infant regulatory symptoms and disorders and the moderating role of parenting stress and global psychological distress. A better understanding of these relationships may inform prevention and intervention programs.

HST/ACS colour-magnitude diagrams of M31 globular clusters [PDF]

, 2009
With the aim of increasing the sample of M31 clusters for which a colour magnitude diagram is available, we searched the HST archive for ACS images containing objects included in the Revised Bologna Catalogue of M31 globular clusters.
