Multiple populations in globular clusters. Lessons learned from the Milky Way globular clusters
Recent progress in studies of globular clusters has shown that they are not
simple stellar populations, being rather made of multiple generations. Evidence
stems both from photometry and spectroscopy. A new paradigm is then arising for
the formation of massive star clusters, which includes several episodes of star
formation. While this provides an explanation for several features of globular
clusters, including the second parameter problem, it also opens new
perspectives about the relation between globular clusters and the halo of our
Galaxy, and by extension of all populations with a high specific frequency of
globular clusters, such as, e.g., giant elliptical galaxies. We review progress
in this area, focusing on the most recent studies. Several points remain to be
properly understood, in particular those concerning the nature of the polluters
producing the abundance pattern in the clusters and the typical timescale, the
range of cluster masses where this phenomenon is active, and the relation
between globular clusters and other satellites of our Galaxy.Comment: In press (The Astronomy and Astrophysics Review

Think glocally, act glocally: a culture-centric comment on Leung, Bhagat, Buchan, Erez and Gibson (2005)
Culture is a critical variable in international business (IB), and Leung, Bhagat, Buchan, Erez and Gibson (2005) enrich our understanding of its role. However, that said, their framing of this variable conflates the role of national culture (NC), a particular form of culture, with culture itself, a more pivotal, holistic and central construct. This paper, by commenting on and critiquing their approach, seeks to shift the theoretical center of gravity from a NC-centric paradigm to a culture-centric, constructivist one, and from a top-down, bottom-up view to a flatter, glocalized one. Implications are provided which suggest that research should address cultural processes of patterning and production, as well as cultural forms, such as global communities and global culture (GC), which share with or even capture the spotlight from NC as a focus for studying and developing IB cultural theory.
