Predicting Chinese Human Resource Managers’ Strategic Competence: roles of identity, career variety, organisational support and career adaptability.

Based on career construction theory, the predictors of human resource managers’ strategic competence in the Chinese context were examined. Results from a survey administered to Chinese HR managers (N = 220) showed that professional identification, career variety and organizational support for strategic human resource management positively predicted Chinese human resource managers’ strategic competence. In addition, career adaptability served as a significant mediator for the above relations. The results further showed that the effect of professional identification on career adaptability was stronger among employees who perceived a higher (vs. lower) level of organizational support for strategic human resource management. The corresponding moderated mediation model was also supported such that the indirect effect of professional identification on strategic competence was stronger among employees who perceived a higher (vs. lower) level of organizational support for strategic human resource management. These findings carry implications for career construction theory and human resource managers’ career development in China
Beyond Mere Application Structure: Thoughts on the Future of Cloud Orchestration Tools

Managing cloud applications running on IaaS is complicated and error prone. This is why DevOps tools and application description languages have been emerging. While these tools and languages enable the user to define the application and communication structure based on application components, they lack the possibility to define sophisticated communication patterns including the wiring on instance level. This paper details these shortcomings and presents approaches to overcome them. In particular, they we propose (i) adding boundaries to wiring specifications and (ii) introducing a higher-level abstraction—called facet—on top of the application. The combination of both concepts allows specifying wiring on basis of logical units and their relations. Hence, the concepts overcome general wiring problems that currently exist in cloud orchestration tools. In addition to that, the introduction of facets improves the re-use of components across different applications
Forward-backward multiplicity correlations in pp collisions at √s = 0.9, 2.76 and 7 TeV

The strength of forward-backward (FB) multiplicity correlations is measured by the ALICE detector in proton-proton (pp) collisions at s√ = 0.9, 2.76 and 7 TeV. The measurement is performed in the central pseudorapidity region (|η| < 0.8) for the transverse momentum p T > 0.3 GeV/c. Two separate pseudorapidity windows of width (δη) ranging from 0.2 to 0.8 are chosen symmetrically around η = 0. The multiplicity correlation strength (b corr) is studied as a function of the pseudorapidity gap (η gap) between the two windows as well as the width of these windows. The correlation strength is found to decrease with increasing η gap and shows a non-linear increase with δη. A sizable increase of the correlation strength with the collision energy, which cannot be explained exclusively by the increase of the mean multiplicity inside the windows, is observed. The correlation coefficient is also measured for multiplicities in different configurations of two azimuthal sectors selected within the symmetric FB η-windows. Two different contributions, the short-range (SR) and the long-range (LR), are observed. The energy dependence of b corr is found to be weak for the SR component while it is strong for the LR component. Moreover, the correlation coefficient is studied for particles belonging to various transverse momentum intervals chosen to have the same mean multiplicity. Both SR and LR contributions to b corr are found to increase with p T in this case. Results are compared to PYTHIA and PHOJET event generators and to a string-based phenomenological model. The observed dependencies of b corr add new constraints on phenomenological models
On Connections Between Graphs, Codes, Quantum States, and Boolean Functions

We study objects that can be represented as graphs, error-correcting
codes, quantum states, or Boolean functions. It is known that self-dual
additive codes, which can also be interpreted as quantum states, can
be represented as graphs, and that two codes are equivalent when the
corresponding graphs are equivalent with respect to local complementation
(LC). We give classifications of such codes. Circulant graph codes
are introduced, and it is shown that some of these codes have highly
regular graph representations. We show that the orbit of a bipartite
graph under edge local complementation (ELC) corresponds to the
equivalence class of a binary linear code. We classify ELC orbits, give
a new method for classifying binary linear codes, and show that the
information sets and the minimum distance of a code can be derived
from the corresponding ELC orbit. Self-dual additive codes over GF(4)
can also be interpreted as quadratic Boolean functions. In this context
we define PARIHN, peak-to-average power ratio with respect to the
{I, H, N}n transform, and prove that PARIHN equals the size of the
maximum independent set over the associated LC orbit of graphs. We
define the aperiodic propagation criteria (APC) of a Boolean function,
and show that it is related to the minimum distance of a self-dual
additive code over GF(4), and to the degree of entanglement in the
associated quantum state. We give a generalization to non-quadratic
Boolean functions, and relate APC to known cryptographic criteria.
Interlace polynomials encode many properties of the LC and ELC orbits
of a graph. We enumerate interlace polynomials and circle graphs,
show that there exist non-unimodal interlace polynomials, and relate
properties of interlace polynomials to properties of codes and quantum
states. We define self-dual bent functions, and provide constructions
and classifications
Assisting natural forest regeneration in northern Ethiopia: one intervention is not enough

Management strategies aimed at rehabilitating degraded and cleared forests often rely on temporary or permanent exclusion of herbivores (wild animals, livestock or both).  But in many cases, this simple management technique is not sufficient to induce ecosystem restoration: many negative effects keep the ecosystem in a suboptimal, low biomass state.  The presence of such stable states requires restoration measures to act on multiple stress factors simultaneously.
Compensating for all limiting factors is neither practically nor economically feasible.  But detailed knowledge about the autoecology of tree species – i.e. their site requirements, regeneration strategies and recruitment dynamics – may be used to tailor management to the most pertinent problems.  Here we illustrate this approach with results from forest restoration experiments in grazing exclosures in northern Ethiopia using African wild olive (Olea europaea ssp. cuspidata) as a representative Afromontane climax species.
The recruitment of African wild olive is affected by seed limitation, restricted seed dispersal and germination and survival limitation.  The exclusion of grazing animals as a single measure to restore forest is not enough.  Degraded grazing land moves into a state dominated by persistent shrubs, arresting forest succession and discouraging local stakeholders.  Direct sowing or planting of seedlings in fertile patches under selected pioneer shrubs, however, may help to overcome this form of bush encroachment, in particular during years with an above-average rainfall.status: publishe
When hadrons become unstable:  a novel type of non-analyticity in chiral extrapolations

Hadron masses show a specific dependence on the quark masses. Therefore, the variation of these masses can cause a resonance in a hadronic scattering amplitude to become a bound state. Consequently, the amplitude exhibits a non-analytic behavior at this transition. Crossed amplitudes, where the resonance can be exchanged in the t-channel, can be shown to exhibit the same phenomenon by s --> t analytic continuation. This entails possible kinks in lattice quark-mass extrapolations needed to compute hadronic observables. (C) 2011 Elsevier B.V. All rights reserved
Adequate bases of phase space master integrals for gg → h at NNLO and beyond

We study master integrals needed to compute the Higgs boson production cross section via gluon fusion in the infinite top quark mass limit, using a canonical form of differential equations for master integrals, recently identified by Henn, which makes their solution possible in a straightforward algebraic way. We apply the known criteria to derive such a suitable basis for all the phase space master integrals in afore mentioned process at next-to-next-to-leading order in QCD and demonstrate that the method is applicable to next-to-next-to-next-to-leading order as well by solving a non-planar topology. Furthermore, we discuss in great detail how to find an adequate basis using practical examples. Special emphasis is devoted to master integrals which are coupled by their differential equations
Higgs-strahlung production process e + e − → Zh at the future Higgs factory in the Minimal Dilaton Model

We investigate the Higgs-strahlung production process e + e − → Zh at the future Higgs factory such as TLEP by including radiative corrections in the Minimal Dilaton Model (MDM), which extends the SM by one singlet scalar called dilaton. We consider various theoretical and experimental constraints on the model, and perform fits to the Higgs data taken from ATLAS, CMS and CDF+D0. Then for the 1 σ surviving samples, we calculate the MDM predictions on the inclusive production rate σ ( e + e − → Zh ) at the 240-GeV Higgs factory, and also the signal rates of e + e − → Zh with the Higgs boson decaying to b b ¯ $$ b\overline{b} $$ and γγ. We have following observations: (1) In the heavy dilaton scenario, the deviation of σ ( e + e − → Zh ) from its SM prediction can vary from −15% to 85%, which mainly arises from the modification of the tree-level hZZ coupling and also the radiative correction induced by possibly large Higgs self-couplings. (2) The processes e + e − → Zh at the Higgs factory and pp → hh at 14-TeV LHC are complementary in limiting the MDM parameter space. Requiring the deviation of σ ( e + e − → Zh ) from its SM prediction to be less than 1% and that of σ ( pp → hh ) to be less than 50%, tan θ S in the MDM will be limited to be −0 . 1 < tan θ S < 0 . 3, and the deviations of the signal rates are constrained to be | R b b ¯ $$ {R}_{b\overline{b}} $$ | < 2% and | R γγ | < 7%. Especially, the Higgs self-coupling normalized to its SM prediction is now upper bounded by about 4. (3) In the light dilaton scenario, the deviation of σ ( e + e − → Zh ) may reach −7%, and requiring its size to be less than 1% will result in 0 < tan θ S < 0 . 1, and −10% < R b b ¯ $$ {R}_{b\overline{b}} $$ , R γγ < 1%
Single-Layered Hittorf’s Phosphorus: A Wide-Bandgap High Mobility 2D Material

We propose here a two-dimensional material based on a single layer of violet or Hittorf’s phosphorus. Using first-principles density functional theory, we find it to be energetically very stable, comparable to other previously proposed single-layered phosphorus structures. It requires only a small energetic cost of approximately 0.04 eV/atom to be created from its bulk structure, Hittorf’s phosphorus, or a binding energy of 0.3 − 0.4 J/m^2 per layer, suggesting the possibility of exfoliation in experiments. We find single-layered Hittorf’s phosphorus to be a wide band gap semiconductor with a direct band gap of approximately 2.5 eV and our calculations show it is expected to have a high and highly anisotropic hole mobility with an upper bound lying between 3000−7000 cm^2V^−1 s^ −1 . These combined properties make single-layered Hittorf’s phosphorus a very good candidate for future applications in a wide variety of technologies, in particular for high frequency electronics, and optoelectronic devices operating in the low wavelength blue color range.This work was supported in part by the EPSRC Grant EP/G007489/2 and EP/J010863/2.

From zero resistance states to absolute negative conductivity in microwave irradiated two-dimensional electron systems

3 pages, 4 figures.Recent experimental results regarding a two-dimensional electron gas subjected to microwave radiation reveal that magnetoresistivity, apart from presenting oscillations and zero resistance states, can evolve to negative values at minima. Here the authors present a theoretical model which explains the transition from zero resistance states to absolute negative conductivity in terms of multiphoton assisted electron scattering due to charged impurities and shows how this transition can be driven by tuning microwave frequency and intensity. This opens the possibility of controlling the magnetoconductivity in microwave driven nanodevices and understanding the novel optical and transport properties of such devices.This work was supported by the\ud

Generalized Chudley-Elliott vibration-jump model in activated atom surface diffusion

5 pages, 2 figures.Here the authors provide a generalized Chudley-Elliott expression for the activated atom surface diffusion which takes into account the coupling between both low-frequency vibrational motion (namely, the frustrated translational modes) and diffusion. This expression is derived within the Gaussian approximation framework for the intermediate scattering function at low coverage. Moreover, inelastic contributions (arising from creation and annihilation processes) to the full width at half maximum of the quasielastic peak are also obtained.This work was supported in part by DGCYT (Spain), Project No. FIS2004-02461.

Kinetics of conformational changes of the FKF1-LOV domain upon photoexcitation.

The photochemical reaction dynamics of a light-oxygen-voltage (LOV) domain from the blue light sensor protein, FKF1 (flavin-binding Kelch repeat F-box) was studied by means of the pulsed laser-induced transient grating method. The observed absorption spectral changes upon photoexcitation were similar to the spectral changes observed for typical LOV domain proteins (e.g., phototropins). The adduct formation took place with a time constant of 6 μs. After this reaction, a significant conformational change with a time constant of 6 ms was observed as a change in the diffusion coefficient. An FKF1-LOV mutant without the conserved loop connecting helices E and F, which is present only in the FKF1/LOV Kelch protein 2/ZEITLUPE family, did not show these slow phase dynamics. This result indicates that the conformational change in the loop region represents a major change in the FKF1-LOV photoreaction
Low post-glacial rebound rates in the Weddell Sea due to Late Holocene ice-sheet readvance.

Many ice-sheet reconstructions assume monotonic Holocene retreat for the West Antarctic Ice Sheet, but an increasing number of glaciological observations infer that some portions of the ice sheet may be readvancing, following retreat behind the present-day margin. A readvance in the Weddell Sea region can reconcile two outstanding problems: (i) the present-day widespread occurrence of seemingly stable ice streams grounded on beds that deepen inland; and (ii) the inability of models of glacial isostatic adjustment to match present-day uplift rates. By combining a suite of ice loading histories that include a readvance with a model of glacial isostatic adjustment we report substantial improvements to predictions of present-day uplift rates, including reconciling one problematic observation of land sinking. We suggest retreat behind present grounding lines occurred when the bed was lower, and isostatic recovery has since led to shallowing, ice sheet re-grounding and readvance. The paradoxical existence of grounding lines in apparently unstable configurations on reverse bed slopes may be resolved by invoking the process of unstable advance, in accordance with our load modelling
A Bayesian approach to portfolios selection in multicriteria group decision making

In the a-posteriori approach to multicriteria decision making the idea is to first find a set of interesting (usually non-dominated) decision alternatives and then let the decision maker select among these.\ud
\ud
Often an additional demand is to limit the size of alternatives to a small number of solutions. In this case, it is important to state preferences on sets. In previous work it has been shown that independent normalization of objective functions (using for instance desirability functions) combined with the hypervolume indicator can be used to formulate such set-preferences.\ud
\ud
A procedure to compute and to maximize the probability that a set of solutions contains at least one satisfactory solution is established. Moreover, we extend the model to the scenario of multiple decision makers. For this we compute the probability that at least one solution in a given set satisfies all decision makers. First, the information required a-priori from the decision makers is considered. Then, a computational procedure to compute the probability for a single set to contain a solution, which is acceptable to all decision makers, is introduced. Thereafter, we discuss how the computational effort can be reduced and how the measure can be maximized. Practical examples for using this in database queries will be discussed, in order to show how this approach relates to applications
Comparison of Sunyaev-Zel’dovich measurements from Planck and from the Arcminute Microkelvin Imager for 99 galaxy clusters

We present observations and analysis of a sample of 123 galaxy clusters from the 2013 Planck catalogue of Sunyaev-Zel’dovich sources with the Arcminute Microkelvin Imager (AMI), a ground-based radio interferometer. AMI provides an independent measurement with higher angular resolution, 3 arcmin compared to the Planck beams of 5–10 arcmin. The AMI observations thus provide validation of the cluster detections, improved positional estimates, and a consistency check on the fitted ‘size’ (θ_s) and ‘flux’ (Y_tot) parameters in the Generalised Navarro, Frenk and White (GNFW) model. We detect 99 of the clusters. We use the AMI positional estimates to check the positional estimates and error-bars produced by the Planck algorithms PowellSnakes and MMF3. We find that Y_tot values as measured by AMI are biased downwards with respect to the Planck constraints, especially for high Planck-SNR clusters. We perform simulations to show that this can be explained by deviation from the ‘universal’ pressure profile shape used to model the clusters. We show that AMI data can constrain the α and β parameters describing the shape of the profile in the GNFW model for individual clusters provided careful attention is paid to the degeneracies between parameters, but one requires information on a wider range of angular scales than are present in AMI data alone to correctly constrain all parameters simultaneously.The AMI telescope is supported by Cambridge University.

A Lattice Boltzmann-Immersed Boundary method to simulate the fluid interaction with moving and slender flexible objects

A numerical approach based on the Lattice Boltzmann and Immersed Boundary methods is proposed to tackle the problem of the interaction of moving and/or deformable slender solids with an incompressible fluid flow. The method makes use of a Cartesian uniform lattice that encompasses both the fluid and the solid domains. The deforming/moving elements are tracked through a series of Lagrangian markers that are embedded in the computational domain. Differently from classical projection methods applied to advance in time the incompressible Navier–Stokes equations, the baseline Lattice Boltzmann fluid solver is free from pressure corrector step, which is known to affect the accuracy of the boundary conditions. Also, in contrast to other immersed boundary methods proposed in the literature, the proposed algorithm does not require the introduction of any empirical parameter. In the case of rigid bodies, the position of the markers delimiting the surface of an object is updated by tracking both the position of the centre of mass of the object and its rotation using Newtonʼs laws and the conservation of angular momentum. The dynamics of a flexible slender structure is determined as a function of the forces exerted by the fluid, its flexural rigidity and the tension necessary to enforce the filament inextensibility. For both rigid and deformable bodies, the instantaneous no-slip and impermeability conditions on the solid boundary are imposed via external and localised body forces which are consistently introduced into the Lattice Boltzmann equation. The validation test-cases for rigid bodies include the case of an impulsively started plate and the sedimentation of particles under gravity in a fluid initially at rest. For the case of deformable slender structures we consider the beating of both a single filament and a pair filaments induced by the interaction with an incoming uniformly streaming flow
