description: We present IRAM 30m sensitive upper limits on CO emission in the ram pressure stripped dwarf Virgo galaxy IC3418 and in a few positions covering HII regions in its prominent 17 kpc UV/Ha gas-stripped tail. In the central few arcseconds of the galaxy, we report a possible marginal detection of about 1x10^6 M_sun of molecular gas (assuming a Galactic CO-to-H_2 conversion factor) that could correspond to a surviving nuclear gas reservoir. We estimate that there is less molecular gas in the main body of IC3418, by at least a factor of 20, than would be expected from the pre-quenching UV-based star formation rate assuming the typical gas depletion timescale of 2 Gyr. Given the lack of star formation in the main body, we think the H_2-deficiency is real, although some of it may also arise from a higher CO-to-H_2 factor typical in low-metallicity, low-mass galaxies. The presence of HII regions in the tail of IC3418 suggests that there must be some dense gas; however, only upper limits of < 1x10^6 M_sun were found in the three observed points in the outer tail. This yields an upper limit on the molecular gas content of the whole tail < 1x10^7 M_sun, which is an amount similar to the estimates from the observed star formation rate over the tail. We also present strong upper limits on the X-ray emission of the stripped gas in IC3418 from a new Chandra observation. The measured X-ray luminosity of the IC3418 tail is about 280 times lower than that of ESO 137-001, a spiral galaxy in a more distant cluster with a prominent ram pressure stripped tail. Non-detection of any diffuse X-ray emission in the IC3418 tail may be due to a low gas content in the tail associated with its advanced evolutionary state and/or due to a rather low thermal pressure of the surrounding intra-cluster medium.

description: We consider phase transitions, in the form of spontaneous symmetry breaking (SSB) bifurcations of solitons, in dual-core couplers with fractional diffraction and cubic self-focusing acting in each core, characterized by Levy index $α$. The system represents linearly-coupled optical waveguides with the fractional paraxial diffraction or group-velocity dispersion (the latter system was used in a recent experiment, which demonstrated the first observation of the wave propagation in an effectively fractional setup). By dint of numerical computations and variational approximation (VA), we identify the SSB in the fractional coupler as the bifurcation of the subcritical type (i.e., the symmetry-breaking phase transition of the first kind), whose subcriticality becomes stronger with the increase of fractionality $2 - α$, in comparison with very weak subcriticality in the case of the non-fractional diffraction, $α= 2$. In the Cauchy limit of $α= 1$, it carries over into the extreme subcritical bifurcation, manifesting backward-going branches of asymmetric solitons which never turn forward. The analysis of the SSB bifurcation is extended for moving (tilted) solitons, which is a nontrivial problem because the fractional diffraction does not admit Galilean invariance. Collisions between moving solitons are studied too, featuring a two-soliton symmetry-breaking effect and merger of the solitons.

description: We experimentally characterize the spatial far-field emission profiles for the two lowest confined modes of a photonic crystal cavity of the L3 type, finding a good agreement with FDTD simulations. We then link the far-field profiles to relevant features of the cavity mode near-fields, using a simple Fabry-Perot resonator model. The effect of disorder on far-field cavity profiles is clarified through comparison between experiments and simulations. These results can be useful for emission engineering from active centers embedded in the cavity.

description: We answer in the affirmative a recently-posed question that asked if there exists an "untypical" convex mapping cone -- i.e., one that does not arise from the transpose map and the cones of k-positive and k-superpositive maps. We explicitly construct such a cone based on atomic positive maps. Our general technique is to consider the smallest convex mapping cone generated by a single map, and we derive several results on such mapping cones. We use this technique to also present several other examples of untypical mapping cones, including a family of cones generated by spin factors. We also provide a full characterization of mapping cones generated by single elements in the qubit case in terms of their typicality.

description: We employ ring-diagram analysis to study the sub-surface thermal structure of active regions. We present results using a large number of active regions over the course of Solar Cycle 23. We present both traditional inversions of ring-diagram frequency differences, with a total sample size of 264, and a statistical study using Principal Component Analysis. We confirm earlier results on smaller samples that sound speed and adiabatic index are changed below regions of strong magnetic field. We find that sound speed is decreased in the region between approximately r=0.99R_sun and r=0.995R_sun (depths of 3Mm to 7Mm), and increased in the region between r=0.97R_sun and r=0.985R_sun (depths of 11Mm to 21Mm). The adiabatic index is enhanced in the same deeper layers that sound-speed enhancement is seen. A weak decrease in adiabatic index is seen in the shallower layers in many active regions. We find that the magnitudes of these perturbations depend on the strength of the surface magnetic field, but we find a great deal of scatter in this relation, implying other factors may be relevant.

description: Ultracool stellar atmospheres show absorption by alkali resonance lines severely broadened by collisions with neutral perturbers. In the coolest and densest atmospheres, such as those of T dwarfs, Na I and K I broadened by molecular hydrogen and helium can come to dominate the entire optical spectrum. The effects of NaHe collision broadening are also central to understanding the opacity of cool DZ white dwarf stars. In order to be able to construct synthetic spectra of brown dwarfs and cool DZ white dwarfs, where helium density can reach several 10^21~cm-3 NaHe line profiles of the resonance lines have been computed over a wide range of densities and temperatures. Unified line profiles that are valid from the core to the far wings at high densities are calculated in the semiclassical approach using up-to-date molecular data including in particular electronic spin-orbit coupling from the sodium atom. We present a comprehensive study of Na-He collisional profiles at high density, and temperatures from 5000~K, the temperature prevailing in the atmosphere of ultra-cool DZ white dwarf stars, down to 1~K, the temperature in liquid helium clusters. Collision broadening and shift parameters within the impact approximation obtained in the semiclassical and quantum theory using our new accurate molecular data are presented.
Efficient and effective management in Higher Education: an insider action research perspective

Educational administration, management and leadership

description: The purpose of this research was to examine the factors that underpin efficient and effective management of the administration services that support academic delivery in an academic school in higher education. It emanated from personal disquiet that my formal management education, with curricula delivered on a discipline basis, had not equipped me to deal with the complex and messy reality of the managerial role. There were six objectives associated with this project: (a) examine effective and efficient management through action research; (b) develop management effectiveness through action research; (c) analyse the factors that underpin, contribute to and affect the manager's efficient and effective delivery of support activities; (d) enhance and develop the researcher's managerial competencies and improve work systems; (e) examine how past managerial experiences affect current practice; and (f) examine the benefits of insider, first person, action research to support managerial activity in a university academic school. An autoethnograhic approach, using reflective narratives, was adopted. The reflective narratives, which form the data for this research, were written over a two year period between spring 2010 and spring 2012, and encompassed the daily activities, both planned and unplanned, mundane and unique of my life as a manager. The findings indicated that effective self-management was a pre-requisite of the successful management of others. Self-management and the management of others requires skills based around four themed areas of emotional management, relationship management, presentation management and the management of roles and tasks. Experience, combined judiciously with formal management education and training (hard skills), ability in the four themed areas (soft skills), and sector and organisational knowledge are required to manage successfully within a university setting. Experiential learning, achieved by structured reflective practice, was found to be an important tool for the improvement of practice through continuing professional development. Action research and reflective practice were useful approaches in the improvement of managerial effectiveness. The manager must be able to apply their professional knowledge according to the situation; this was when tacit knowledge-in-action was required. The findings suggest, therefore, the need to educate managers in the acquistion of structured reflective practice. Formal management education should teach students about the need for and the development of the soft skills pertaining to the management of emotions, relationships, self-presentation and of roles and tasks in themselves and others. This thesis has important implications for management education and for the continuing professional and personal development of practising managers.

description: Bi-layer graphene with a twist angle θ between the layers generates a superlattice structure known as Moiré pattern. This superlattice provides a θ-dependent q wavevector that activates phonons in the interior of the Brillouin zone. Here we show that this superlattice-induced Raman scattering can be used to probe the phonon dispersion in twisted bi-layer graphene (tBLG). The effect reported here is different from the broadly studied double-resonance in graphene-related materials in many aspects, and despite the absence of stacking order in tBLG, layer breathing vibrations (namely ZO' phonons) are observed.

description: Quantum anomalous Hall effect (QAHE) is a fundamental transport phenomenon in the field of condensed-matter physics. Without external magnetic field, spontaneous magnetization combined with spin-orbit coupling give rise to a quantized Hall conductivity. So far, a number of theoretical proposals have been made to realize the QAHE, but all based on inorganic materials. Here, using first-principles calculations, we predict a family of 2D organic topological insulators (OTIs) for realizing the QAHE. Designed by assembling molecular building blocks of triphenyl-transition-metal compounds into a hexagonal lattice, this new classes of organic materials are shown to have a nonzero Chern number and exhibit a gapless chiral edge state within the Dirac gap.

Το Radiance αποτελεί ένα πακέτο λογισμικού για ηλεκτρονικό υπολογιστή. Πρόκειται για ένα ερευνητικό εργαλείο με σκοπό τον ακριβή υπολογισμό της ορατής ακτινοβολίας στο χώρο. Το Radiance πλεονεκτεί έναντι άλλων προγραμμάτων φωτισμού διότι χρησιμοποιεί τεχνική προσομοίωσης ray-tracing που επιτρέπει τον υπολογισμό των ανακλάσεων σε όλες τις επιφάνειες του χώρου στο τελικό αποτέλεσμα. Το πρώτο στάδιο της προσομοίωσης περιλαμβάνει την κατασκευή της γεωμετρίας του χώρου, δηλαδή του δωματίου μέσω εντολών μοντελοποίησης του προγράμματος και την εισαγωγή των φωτιστικών σε αυτό. Στη συνέχεια πραγματοποιείται ο υπολογισμός του φυσικού φωτισμού σε ωριαία βάση. Το τρίτο στάδιο της εργασίας περιλαμβάνει τον υπολογισμό της έντασης του φωτισμού σε συγκεκριμένα σημεία. Το τελικό αποτέλεσμα δηλαδή το άθροισμα των τιμών του τεχνητού και του φυσικού φωτισμού πραγματοποιείται και παρουσιάζεται με τη βοήθεια του Matlab.

description: In this paper we illustrate the potential role which relative limit cycles may play in biolocomotion. We do this by describing, in great detail, an elementary example of reduction of a lightly dissipative system modeling crawling-type locomotion in 3D. The symmetry group SE(2) is the set of rigid transformations of the horizontal (ground) plane. Given a time-periodic perturbation, the system will admit a relative limit cycle whereupon each period is related to the previous by a fixed translation and rotation along the ground. This toy model identifies how symmetry reduction and dissipation can conspire to create robust behavior in crawling, and possibly walking, locomotion.

description: Stars with masses above 1.6 solar masses generally possess convective cores and radiative envelopes, which allows the propagation of outward-travelling internal gravity waves. We have studied the generation and propagation of IGWs in such stars using two-dimensional, fully nonlinear hydrodynamical simulations with realistic stellar reference states from the one-dimensional stellar evolution code, Modules for Stellar Astrophysics. Compared to previous similar works, this study utilises radius-dependent thermal diffusivity profiles for 5 different stellar masses at the middle of main sequence: 3 - 13 solar masses. From the simulations, we find that the surface perturbations are larger for higher masses, but no noticeable trends are observed for the frequency slopes with different stellar masses. The slopes are also similar to the results from previous works. We compare our simulation results with stellar photometric data from a recent survey and find that for frequency intervals above 8 microHz, there is a good agreement between the temperature frequency slopes from the simulations and the surface brightness variations of these observed stars, indicating that the brightness variations are caused by core-generated IGWs.

description: Treatment effect estimation is of high-importance for both researchers and practitioners across many scientific and industrial domains. The abundance of observational data makes them increasingly used by researchers for the estimation of causal effects. However, these data suffer from biases, from several weaknesses, leading to inaccurate causal effect estimations, if not handled properly. Therefore, several machine learning techniques have been proposed, most of them focusing on leveraging the predictive power of neural network models to attain more precise estimation of causal effects. In this work, we propose a new methodology, named Nearest Neighboring Information for Causal Inference (NNCI), for integrating valuable nearest neighboring information on neural network-based models for estimating treatment effects. The proposed NNCI methodology is applied to some of the most well established neural network-based models for treatment effect estimation with the use of observational data. Numerical experiments and analysis provide empirical and statistical evidence that the integration of NNCI with state-of-the-art neural network models leads to considerably improved treatment effect estimations on a variety of well-known challenging benchmarks.

description: Top-down fabricated GaN nanowires, 250 nm in diameter and with various heights, have been used to experimentally determine the evolution of strain along the vertical direction of 1-dimensional objects. X-ray diffraction and photoluminescence techniques have been used to obtain the strain profile inside the nanowires from their base to their top facet for both initial compressive and tensile strains. The relaxation behaviors derived from optical and structural characterizations perfectly match the numerical results of calculations based on a continuous media approach. By monitoring the elastic relaxation enabled by the lateral free-surfaces, the height from which the nanowires can be considered strain-free has been estimated. Based on this result, NWs sufficiently high to be strain-free have been coalesced to form a continuous GaN layer. X-ray diffraction, photoluminescence and cathodoluminescence clearly show that despite the initial strain-free nanowires template, the final GaN layer is strained.

description: Heisenberg's uncertainty principle implies fundamental constraints on what properties of a quantum system can we simultaneously learn. However, it typically assumes that we probe these properties via measurements at a single point in time. In contrast, inferring causal dependencies in complex processes often requires interactive experimentation - multiple rounds of interventions where we adaptively probe the process with different inputs to observe how they affect outputs. Here we demonstrate universal uncertainty principles for general interactive measurements involving arbitrary rounds of interventions. As a case study, we show that they imply an uncertainty trade-off between measurements compatible with different causal dependencies.

description: We investigate whether a neural network approach can reproduce and predict the electron-nucleus cross sections in the kinematical domain of present and future accelerator-based neutrino oscillation experiments. For this purpose, we consider the large amount of data available to the community via the web-page ``Quasielastic Electron Nucleus scattering archive'', and use a residual, fully connected feedforward neural network. We illustrate the training performances of the neural network by comparing its results with experimental data for the electron double-differential cross section on carbon. The agreement between predictions and data is remarkable from quasielastic to deep-inelastic scattering. To test the predicting power of the neural network we consider the numerous kinematical conditions for which experimental cross sections on calcium are available. Furthermore, we show the predictions of the electron scattering cross sections on oxygen, argon, and titanium: nuclei of particular interest in the context of present and future accelerator-based neutrino oscillation program. The agreement between these predictions and the data is comparable to the one of other theoretical models commonly used to calculate electron and neutrino cross sections, such as SuSAv2 and GiBUU. Results obtained with GENIE, a Monte Carlo event generator, are also discussed for comparison. The good performances obtained with our neural network suggest that neural networks could be exploited for theoretical and experimental investigations of electron- and neutrino-nucleus scattering.
A feasibility study for a randomised controlled trial using the Personal Aspirations and Concerns Inventory for Offenders (PACIO) to improve short-term offenders’ motivation for, and participation in, custodial education and to reduce reconviction

Subjects: Applied and developmental psychology not elsewhere classified

description: Offenders’ treatment motivation has been linked to improved treatment engagement (Sellen et al, 2009; Campbell et al., 2010) and in turn treatment completion is associated with better rehabilitation outcomes (McMurran & Theodosi, 2007). Custodial education has been suggested to reduce reoffending (e.g., Zgoba et al., 2008) and so it may be useful to develop ways of motivating offenders to participate in custodial workshops and education classes. Firstly, the exploratory study investigated post-release employment issues in short-term offenders (STOs) sentenced to custody of less than 12 months. Secondly, the main study described a feasibility study examining STOs’ motivation to participate in education. The Personal Aspiration and Concerns Inventory for Offenders (PACIO) is a goal-based motivational interview aimed at enhancing treatment motivation and assessing its adaptive and maladaptive dimensions (Campbell et al., 2010). Firstly, the PACIO was used as a preparatory motivational intervention to investigate its effect on education participation compared with STOs who received the PACIO plus a motivational interview (PACIO plus) and a nonintervention. Secondly, the effect of education participation on reconviction rates was investigated. Thirdly, the influence of adaptive motivation (AM) and learned helplessness/ powerlessness (LH/P) profiles were investigated in terms of education participation. The PACIO and PACIO plus did not increase STOs’ motivation and education participation. However, education participation reduced reconviction. AM and LH/P did not predict education participation. Since these results did not confirm the hypothesised outcomes, it is not feasible to use the PACIO or the PACIO plus to improve and assess STOs’ motivation for and participation in custodial education. Future research should focus on developing an effective preparatory motivational intervention for STOs to participate in education.

description: Many experiments operating at millikelvin temperatures with signal frequencies in the microwave regime are beginning to incorporate Josephson Parametric Amplifiers (JPA) as their first amplification stage. While there are implementations for a wideband frequency response with a minimal need for tuning, designs using resonant structures with small numbers of Josephson elements still achieve the best noise performance. In a typical measurement scheme involving a JPA, one needs to control the resonance frequency, pump frequency and pump power to achieve the desired amplification and noise properties. In this work, we propose a straightforward approach for operating JPAs with the help of a look-up table (LUT) and online fine-tuning. Using the proposed approach, we demonstrate the operation of a flux-driven JPA with 20 dB gain around 5.9 GHz, covering approximately 100 MHz with 20 kHz tuning steps. The proposed methodology was successfully used in the context of a haloscope axion experiment.

description: The paper deals with the process of introducing mercantile principles into the Habsburg financial
administration. A lot of ideas were already suggested by the economic thinkers of the 2nd half of the
17th century such as Johann Joachim Becher or Philipp Wilhelm of Hörnigk. Of course this is well
known but the article tries to illustrate the struggle of the Habsburg counselors for improving
government and administration in the Habsburg lands. Only in the first half of the 18th century
several suggestions were implemented (again) which is the credit of influential groups and
individuals at the Viennese court. Count Gundacker Thomas Starhemberg was one of them. The
second part of the paper concentrates on the newly created Secret Financial Conference which was
strongly influenced by Starhemberg and its attempts to implement the mentioned principles.

description: We study the geometry of the transition layer (TL) between the classical Keplerian accretion disk (the TL outer boundary) and the compact object at the TL inner boundary. Our goal is to demonstrate using the hydrodynamical formalism that the TL is created along with a shock due to a discontinuity and to an adjustment of the Keplerian disk motion to a central object. We apply hydrodynamical equations to describe a plasma motion near a central object in the TL. We point out that before matter accretes to a central object the TL cloud is formed between an adjustment radius and the TL inner boundary which is probably a site where the emergent Compton spectrum comes from. Using a generalization of the Randkine-Hugoniot relation and a solution of the azimutal force balance equation we have reproduced the geometric characteristics of TL.

description: We prove existence of isoperimetric regions for every volume in non-compact Riemannian $n$-manifolds $(M,g)$, $n\geq 2$, having Ricci curvature $Ric_g\geq (n-1) k_0 g$ and being locally asymptotic to the simply connected space form of constant sectional curvature $k_0$; moreover in case $k_0=0$ we show that the isoperimetric regions are indecomposable. We also discuss some physically and geometrically relevant examples. Finally, under assumptions on the scalar curvature we prove existence of isoperimetric regions of small volume.

A critical realist study of quality management in Nigerian Universities
Creators: name: ADETUNJI, ADENIYI TEMITOPE
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Higher education

description: This critical realist study is an investigation of the experiences of principal officers during the research was necessitated by a general lack of knowledge about how quality management implementation occurs in the Nigerian university context. The thesis main research question was how have Nigerian universities been responding to quality management implementation’. The thesis uses a critical realist paradigm and adopts a qualitative approach to unveil the causes of events. This study rejects the positivist preoccupations with prediction, quantification and measurement used by earlier researchers to determine quality management in developed countries and to replicate the approach in a country like Nigeria. The study adopts a critical realist approach, since critical realism gives primacy to the social and personal identity of human values of emancipation rather than material concerns, which are subject to measurement. The study uses semi-structured interviews to discover causal and missing mechanisms from twenty-nine principal officers in six universities. Thematic Analysis was adopted to analyse the themes that emerged from the empirical findings, and used to analyse the causal mismatch between the theory and the reality observed. The approach was used to clarify the blame attributed to the implementation of quality management and government policies rather than philosophical inappropriateness. The approach provides a starting point for querying any unexamined ideology operating in various universities in Nigeria. The findings reveal that many competing voices are operating in different parts of the sector. This has effects on the structure, causing the mechanism to function wrongly, with a lack of a common platform to understand government policies and quality management. Finally, the thesis’s contribution to knowledge includes the using critical realist approach to review relevant literature related to quality management. Its Methodological contribution is through the use of a critical realist approach to produce a social and personal identity of principal officers involved and re-descriptive narrative account of events that have been hitherto unexplored locally and internationally

description: We study models of emergent space associated with the Coulomb branch, non-commutative and beta deformations of the N=4 super Yang-Mills theory, extending a previous work on the undeformed conformal case. The idea is to compute the effective action for D-instantons from the microscopic four-dimensional open-string description and to compare with the non-abelian D-instanton action in the dual ten-dimensional supergravity background. To linear order in the deformation parameter, the D-instantons can probe the full space-time geometry and we can derive all the supergravity fields in this way. We find a perfect match with the known supergravity solutions, including for the Neveu-Schwarz and Ramond-Ramond forms.

Heteroclinic Switching between Chimeras in a Ring of Six Oscillator Populations

description: In a network of coupled oscillators, a symmetry-broken dynamical state characterized by the coexistence of coherent and incoherent parts can spontaneously form. It is known as a chimera state. We study chimera states in a network consisting of six populations of identical Kuramoto-Sakaguchi phase oscillators. The populations are arranged in a ring and oscillators belonging to one population are uniformly coupled to all oscillators within the same population and to those in the two neighboring populations. This topology supports the existence of different configurations of coherent and incoherent populations along the ring, but all of them are linearly unstable in most of the parameter space. Yet, chimera dynamics is observed from random initial conditions in a wide parameter range, characterized by one incoherent and five synchronized populations. These observable states are connected to the formation of a heteroclinic cycle between symmetric variants of saddle chimeras, which gives rise to a switching dynamics. We analyze the dynamical and spectral properties of the chimeras in the thermodynamic limit using the Ott-Antonsen ansatz, and in finite-sized systems employing Watanabe-Strogatz reduction. For a heterogeneous frequency distribution, a small heterogeneity renders a heteroclinic switching dynamics asymptotically attracting. However, for a large heterogeneity, the heteroclinic orbit does not survive; instead, it is replaced by a variety of attracting chimera states.

Must the Communication Graph of MPC Protocols be an Expander?

description: Secure multiparty computation (MPC) on incomplete communication networks has been studied within two primary models: (1) Where a partial network is fixed a priori, and thus corruptions can occur dependent on its structure, and (2) Where edges in the communication graph are determined dynamically as part of the protocol. Whereas a rich literature has succeeded in mapping out the feasibility and limitations of graph structures supporting secure computation in the fixed-graph model (including strong classical lower bounds), these bounds do not apply in the latter dynamic-graph setting, which has recently seen exciting new results, but remains relatively unexplored. In this work, we initiate a similar foundational study of MPC within the dynamic-graph model. As a first step, we investigate the property of graph expansion. All existing protocols (implicitly or explicitly) yield communication graphs which are expanders, but it is not clear whether this is inherent. Our results consist of two types (for constant fraction of corruptions): * Upper bounds: We demonstrate secure protocols whose induced communication graphs are not expander graphs, within a wide range of settings (computational, information theoretic, with low locality, even with low locality and adaptive security), each assuming some form of input-independent setup. * Lower bounds: In the plain model (no setup) with adaptive corruptions, we demonstrate that for certain functionalities, no protocol can maintain a non-expanding communication graph against all adversarial strategies. Our lower bound relies only on protocol correctness (not privacy), and requires a surprisingly delicate argument. More generally, we provide a formal framework for analyzing the evolving communication graph of MPC protocols, giving a starting point for studying the relation between secure computation and further, more general graph properties.
