ORGANIZATIONAL CULTURE AND EFFECTIVENESS: CAN AMERICAN THEORY BE APPLIED IN RUSSIA?
This paper examines the link between organizational culture and effectiveness for foreign-owned firms operating in Russia. Beginning with a model of organizational culture developed in the USA, the paper presents a multi-method analysis of culture and effectiveness in a transition economy. We argue that effectiveness in Russia relies more on adaptability and flexibility than in the USA. Furthermore, the legacy of the communist era forces firms in Russia to deal with a workforce with a unique time perspective and a unique set of sub-cultures that often undermine attempts at coordination and integration. We first explore these ideas using survey data on 179 foreign-owned firms operating in Russia and compare the results to those obtained for firms in the USA. We then present four case studies designed to ground the results in the Russian context, and to document cultural dynamics not captured by the model.http://deepblue.lib.umich.edu/bitstream/2027.42/39984/3/wp598.pd
A note on the abelian sandpile in Z^d
We analyse the abelian sandpile model on \mathbbm{Z}^d for the starting
configuration of particles in the origin and particles otherwise. We
give a new short proof of the theorem of Fey, Levine and Peres \cite{FLP} that
the radius of the toppled cluster of this configuration is
Bendings of radio jets in BL Lacertae objects I: EVN and MERLIN observations
Several blazars, and BL Lac objects in particular, show a misalignment
between the jet orientation on parsec and kiloparsec scales. Some authors (i.e.
Conway & Murphy, 1993) have attempted to explain this behaviour invoking
helical jets for misalignment angles around 90\degr, showing how in this case
there are interesting implications for the understanding of the medium into
which the jet is expanding. By comparing sensitive VLA observations (Cassaro et
al., 1999) with images available in the literature for the BL Lac objects from
the 1-Jy Sample (Stickel et al., 1991), it is clear that there is a wide range
of misalignments between the initial jet direction and the kpc-scale jet, when
detected. We have carried out VLBI observations of these BL Lac objects, in
order to investigate the spatial evolution of the radio jets from few tens to
hundreds of mas, and to search for helical jets in this class of sources. We
present here the first dataset obtained from EVN+MERLIN observations at 5 GHz
for seven objects. From these observations we never have a clear detection of
helical jets, we only have a possible signature of their presence in 2 objects.
In only one of the sources with a misalignment angle around 90\degr the
presence of helical jets can be ruled out. This implies that it is not possible
to invoke helical jets to explain the morphology of all the sources showing a
misalignment of about 90\degr between the parsec and the kiloparsec scale
jets.Comment: 12 pages, 9 figures, latex, accepted by Astronomy & Astrophysic

Driving sandpiles to criticality and beyond
A popular theory of self-organized criticality relates driven dissipative
systems to systems with conservation. This theory predicts that the stationary
density of the abelian sandpile model equals the threshold density of the
fixed-energy sandpile. We refute this prediction for a wide variety of
underlying graphs, including the square grid. Driven dissipative sandpiles
continue to evolve even after reaching criticality. This result casts doubt on
the validity of using fixed-energy sandpiles to explore the critical behavior
of the abelian sandpile model at stationarity.Comment: v4 adds referenc
The Spotted Lanternfly in Gettysburg and Public Mobilization Through an Awareness Campaign
The invasive Spotted Lanternfly poses a significant risk to the environment and fruit industry of Adams County PA. This project involves the creation of an informational poster campaign to inform the geographically diverse daily population of Gettysburg about the spotted lanternfly and mobilize them to take action against it
Characterisation of Long Baseline Calibrators at 2.3 GHz
We present a detailed multi-epoch analysis of 31 potential southern
hemisphere radio calibrators that were originally observed as part of a program
to maintain the International Celestial Reference Frame (ICRF). At radio
wavelengths, the primary calibrators are Active Galactic Nuclei (AGN), powerful
radio emitters which exist at the centre of most galaxies. These are known to
vary at all wavelengths at which they have been observed. By determining the
amount of radio source structure and variability of these AGN, we determine
their suitability as phase calibrators for long baseline radio interferometry
at 2.3 GHz. For this purpose, we have used a set of complementary metrics to
classify these 31 southern sources into five categories pertaining to their
suitability as VLBI calibrators. We find that all of the sources in our sample
would be good interferometric calibrators and almost ninety per cent would be
very good calibrators.Comment: 9 pages, 7 Figures, accepted MNRA
