Bringing Hidden Organizations Out of the Shadows: Introduction to the Special Issue
No full textThis introduction to the special issue describes hidden organizations, offers several reasons for the lack of research on these collectives, and explains how this collection of articles helps move us forward in efforts to empirically study hidden organizations. After providing background information on the history of this special issue, the five articles published here are described in terms of the type of collective examined, the theories and methods used, and the key research questions addressed. Three observations about the published pieces are made: being hidden requires communicative effort; hiddenness is usefully understood in terms of identity management; and any discussion of hidden organizations raises ethical considerations. The piece closes with acknowledgements and a call for continued conceptual/theoretical and empirical research into hidden organizations.This is an introduction to a special issue on Hidden Organizations edited by the author.

Cometary dust in astrophysics
No full textThe purpose of the meeting was the integration of astrophysical observations of comets and interstellar/circumstellar dust with laboratory analyses of interplanetary dust particles, stardust, and meteorites, and to discuss what we hope to learn from comet samples to be returned by Stardust in 2006.University of Washington, Lunar and Planetary Institute, NASA Johnson Space Centermeeting organizers, Don E.

Let's Call a Star a Star: Task Performance, External Status, and Exceptional Contributors in Organizations
No full textWe develop a new typology of star employees, wherein we identify three types of stars – universal stars, performance stars, and status stars – on the basis of stars’ unique combinations of task performance and external status. By classifying stars in this way and disentangling task performance and external status as unique and simultaneously important qualities underlying the distinct contributions of different types of stars, we provide a basis for more accurately identifying the full range of individuals who create exceptional value, and offer novel insights into stars’ various influences in organizations. With this foundation, we explore how different types of stars’ distinct qualities and bases of value creation affect both the security of their star standing and their relative abilities to appropriate value. We then expand our focus to consider stars in the broader organizational contexts in which they exist, discussing the implications of stars’ distinct attributes for patterns of value creation, value capture, and value preservation associated with stars’ complementarities and redundancies with other organizational resources. Finally, we propose several lines of inquiry through which future research may leverage the proposed typology to address issues related to the management of different types of stars in the broader organizational contexts in which they are embedded
Belonging and not belonging : understanding India in novels by Paul Scott, Ruth Prawer Jhabvala and V.S. Naipaul.
No full textPhDThis thesis is essentially about the "how" and "why" of the Indian
experience as documented in novels by Paul Scott, Ruth Prawer Jhabvala
and V S Naipaul. The study points to the difficulty of arriving at any
conclusive definition of the country and its people. I show that
differences in attitudes, responses or behaviour are both overt and
subtle, and depend upon whether the writer or the character identifies
with the situation or community with which he or she interacts. It is
the individual's sense of belonging or not belonging to his or her own
group - be this along racial, cultural or gender lines - that accounts
for the differing perspectives evident in these novels. The points-of-
view of the outsider and the insider can therefore be seen as
mutual comments upon the other.
Since the struggle between belonging and not belonging becomes acute
when the old meets the new, focus is centred on communities
experiencing change. These include the British in India, West-Indian
Indians and westernised Indians. Despite their differences, all three
communities share similar reasons for either an acceptance or
rejection of the 'Other'. The thesis argues that the need for
emotional stability compels allegiance to the traditional group, while
the desire for individuality encourages surrender to the new. The
former nurtures a sense of belonging while, it is argued, that the
latter is perceived as the hallmark of those who do not belong.
Tensions arise when both these needs demand to be met. What I show to
be ironic in this struggle between belonging and not belonging is that
those things which individuals overtly reject are often unexpressed
parts of their personal pysche. The barrier between "them" and "us" is
therefore very fragile
Dr. Scott Allison and Dr. Al Goethals – Faculty Author Interview
No full textDr. Scott Allison, Professor, Department of Psychology and Dr. Al Goethals, Professor, Jepson School of Leadership Studies discuss their recent book, Heroes: What They Do and Why We Need Them. Published by Oxford University Press, the book offers a stimulating tour of the psychology of heroism, shedding light on what heroism and villainy mean to most people and why heroes — both real people and fictional characters — are so vital to our lives.

Kraichnan-Leith-Batchelor similarity theory and two-dimensional inverse cascades
No full textWe study the scaling properties and Kraichnan-Leith-Batchelor (KLB) theory of forced inverse cascades in generalized two-dimensional (2D) fluids (-turbulence models) simulated at resolution . We consider (surface quasigeostrophic flow), (2D vorticity dynamics) and . The forcing scale is well-resolved, a direct cascade is present and there is no large-scale dissipation. Coherent vortices spanning a range of sizes, most larger than the forcing scale, are present for both and . The active scalar field for contains comparatively few and small vortices. The energy spectral slopes in the inverse cascade are steeper than the KLB prediction in all three systems. Since we stop the simulations well before the cascades have reached the domain scale, vortex formation and spectral steepening are not due to condensation effects; nor are they caused by large-scale dissipation, which is absent. One- and two-point pdfs, hyperflatness factors and structure functions indicate that the inverse cascades are intermittent and non-Gaussian over much of the inertial range for and , while the inverse cascade is much closer to Gaussian and non-intermittent. For the steep spectrum is close to that associated with enstrophy equipartition. Continuous wavelet analysis shows approximate KLB scaling () and () in the interstitial regions between the coherent vortices. Our results demonstrate that coherent vortex formation ( and ) and non-realizability () cause 2D inverse cascades to deviate from the KLB predictions, but that the flow between the vortices exhibits KLB scaling and non-intermittent statistics for and . The results will appear in \cite{BurgessEA2015}, which has been accepted to the \emph{Journal of Fluid Mechanics}
