Transferring management practices to China: a Bourdieusian critique of ethnocentricity
This paper provides a critique of the emergent theories of human resource management in China with a view to generating new theoretical insights with particular reference to Pierre Bourdieu's social theory. It reassesses the relevance of the orthodox critique of ethnocentricity and the coherence of approaches embedded in Chinese culture. With reference to six case studies of the largest retail firms, we identify two key challenges: the reliance on headquarter human resource practices that reflect an ethnocentric ethos, i.e. country-of-origin bias, and the failure to empower local managers and the problems this creates for managers expected to implement ethnocentric practices. We examine how Bourdieu's social theory sheds light on the processes by which these firms realise their strategic objectives through the complicity of local managers whose scope for resistance is constrained by the use of normative control and in part through attractive remuneration and career prospects that generate Bourdieusian capital for these managers. We conclude with some suggestions for further research
Food activities and identity maintenance in old age: a systematic review and meta-synthesis
This article has been made available through the Brunel Open Access Publishing Fund.Objectives: Services provided to older people should be developed based on active ageing policies. Nutrition is one aspect of active ageing, but little is known about how food activities contribute to psychological well-being in later life. This is a systematic review of qualitative and quantitative research that answers the question ‘What is known about the relationship between food activities and the maintenance of identities in old age?’
On time-dependent AdS/CFT
We clarify aspects of the holographic AdS/CFT correspondence that are typical
of Lorentzian signature, to lay the foundation for a treatment of
time-dependent gravity and conformal field theory phenomena. We provide a
derivation of bulk-to-boundary propagators associated to advanced, retarded and
Feynman bulk propagators, and provide a better understanding of the boundary
conditions satisfied by the bulk fields at the horizon. We interpret the
subleading behavior of the wavefunctions in terms of specific vacuum
expectation values, and compute two-point functions in our framework. We
connect our bulk methods to the closed time path formalism in the boundary
field theory.Comment: 19 pages, v2: added reference, JHEP versio
Patterns of ‘balancing between hope and despair’ in the diagnostic phase: a grounded theory study of patients on a gastroenterology ward
Aim: The aim of the study was to learn how patients going through the diagnostic phase experienced and handled their situation. Background: Many studies report about the stressful diagnostic phase; however, none has presented a conceptual theory where the concepts are sufficiently related to each other. The Theory of Preparative Waiting has previously been published as a descriptive grounded theory and describes the experience of a group of gastroenterology patients going through the diagnostic phase. Method: A classical grounded theory design was used, with data derived from 18 in-depth interviews with 15 patients in a gastroenterology ward at a Norwegian University Hospital. Interviews were conducted during 2002–2003. Findings: Participants’ main concern was found to be how they could prepare themselves for the concluding interview and life after diagnosis. The theoretical code of ‘balancing’ had four patterns; controlling pain, rational awaiting, denial, and accepting. These patterns of ‘balancing’ guided how participants used the categories of ‘Preparative Waiting Theory’ ‘seeking and giving information’, ‘interpreting clues’, ‘handling existential threats’ and ‘seeking respite’. Patterns were strategies, so one person could use more than one pattern. Conclusion: The diagnostic phase was a difficult time for the participants and the ‘Preparative Waiting Theory’ can assist nurses in assessing how patients prepare themselves differently for getting a diagnosis. All patients would find it helpful to be followed up by a designated contact person at the ward; however, patients using mostly the patterns of controlling pain and denial would benefit most from such support
Bouncing back from failure: Entrepreneurial resilience and the internationalization of subsequent ventures created by serial entrepreneurs
This paper examines the impact over international propensity of past negative entrepreneurial experience for those who re-enter into entrepreneurial activity; referred to as resilient serial entrepreneurs. We first hypothesize on the effects over entrepreneurial re-entry that such negative past experience may have and highlight the link between the past entrepreneurial experience of resilient entrepreneurs and their subsequent propensity towards international markets. Building on insights from the generative experiential learning process of entrepreneurial activity and from cognition theories, we propose that resilient entrepreneurs who re-enter business despite having faced negative entrepreneurial experiences in the past benefit from enriched cognitive schemas leading them to greater export propensity. The proposed hypotheses are tested on a unique sample drawn from a Spanish adult population survey. Results from the sequential deductive triangulation analysis (QUAN -> qual) reveal that practical experience is an essential prerequisite for entrepreneurial learning, and that the resilience of those with negative entrepreneurial experience induces the generative entrepreneurial learning especially suitable for subsequent internationally oriented ventures.Peer ReviewedPreprin
Light-Front Quantisation as an Initial-Boundary Value Problem
In the light front quantisation scheme initial conditions are usually
provided on a single lightlike hyperplane. This, however, is insufficient to
yield a unique solution of the field equations. We investigate under which
additional conditions the problem of solving the field equations becomes well
posed. The consequences for quantisation are studied within a Hamiltonian
formulation by using the method of Faddeev and Jackiw for dealing with
first-order Lagrangians. For the prototype field theory of massive scalar
fields in 1+1 dimensions, we find that initial conditions for fixed light cone
time {\sl and} boundary conditions in the spatial variable are sufficient to
yield a consistent commutator algebra. Data on a second lightlike hyperplane
are not necessary. Hamiltonian and Euler-Lagrange equations of motion become
equivalent; the description of the dynamics remains canonical and simple. In
this way we justify the approach of discretised light cone quantisation.Comment: 26 pages (including figure), tex, figure in latex, TPR 93-
Oscillations and waves in solar spicules
Since their discovery, spicules have attracted increased attention as energy/mass bridges between the dense and dynamic photosphere and the tenuous hot solar corona. Mechanical energy of photospheric random and coherent motions can be guided by magnetic field lines, spanning from the interior to the upper parts of the solar atmosphere, in the form of waves and oscillations. Since spicules are one of the most pronounced features of the chromosphere, the energy transport they participate in can be traced by the observations of their oscillatory motions. Oscillations in spicules have been observed for a long time. However the recent high-resolutions and high-cadence space and ground based facilities with superb spatial, temporal and spectral capacities brought new aspects in the research of spicule dynamics. Here we review the progress made in imaging and spectroscopic observations of waves and oscillations in spicules. The observations are accompanied by a discussion on theoretical modelling and interpretations of these oscillations. Finally, we embark on the recent developments made on the presence and role of Alfven and kink waves in spicules. We also address the extensive debate made on the Alfven versus kink waves in the context of the explanation of the observed transverse oscillations of spicule axes
Free energy of colloidal particles at the surface of sessile drops
The influence of finite system size on the free energy of a spherical
particle floating at the surface of a sessile droplet is studied both
analytically and numerically. In the special case that the contact angle at the
substrate equals a capillary analogue of the method of images is
applied in order to calculate small deformations of the droplet shape if an
external force is applied to the particle. The type of boundary conditions for
the droplet shape at the substrate determines the sign of the capillary
monopole associated with the image particle. Therefore, the free energy of the
particle, which is proportional to the interaction energy of the original
particle with its image, can be of either sign, too. The analytic solutions,
given by the Green's function of the capillary equation, are constructed such
that the condition of the forces acting on the droplet being balanced and of
the volume constraint are fulfilled. Besides the known phenomena of attraction
of a particle to a free contact line and repulsion from a pinned one, we
observe a local free energy minimum for the particle being located at the drop
apex or at an intermediate angle, respectively. This peculiarity can be traced
back to a non-monotonic behavior of the Green's function, which reflects the
interplay between the deformations of the droplet shape and the volume
constraint.Comment: 24 pages, 19 figure

Investigating the PDR process in a UK university: continuing professional development or performativity?
Over recent years, the professional development review process has risen in importance in universities with such exercises being shown to have a positive effect on student learning, staff motivation, recruitment and retention. However, they may also be perceived as a controlling mechanism and part of a culture of ‘performativity’, which implies a lack of trust, an undermining of autonomy and a reliance on externally driven targets to ‘manage’ staff. However, there is very little published research in this area. This paper addresses this knowledge gap by drawing on data from a Leadership Foundation funded study in a UK University which included 30 interviews and a follow up survey (n=177) with both leaders and the staff they lead. The findings suggest that both leaders and staff felt that the process was potentially very important and could offer significant levels of guidance and support for professional development. However, they stressed the importance of a review structure which was adaptable, more professionally relevant, and less reliant on over ambitious target setting
Moduli and (un)attractor black hole thermodynamics
We investigate four-dimensional spherically symmetric black hole solutions in
gravity theories with massless, neutral scalars non-minimally coupled to gauge
fields. In the non-extremal case, we explicitly show that, under the variation
of the moduli, the scalar charges appear in the first law of black hole
thermodynamics. In the extremal limit, the near horizon geometry is
and the entropy does not depend on the values of moduli at
infinity. We discuss the attractor behaviour by using Sen's entropy function
formalism as well as the effective potential approach and their relation with
the results previously obtained through special geometry method. We also argue
that the attractor mechanism is at the basis of the matching between the
microscopic and macroscopic entropies for the extremal non-BPS Kaluza-Klein
black hole.Comment: 36 pages, no figures, V2: minor changes, misprints corrected,
