description: For a (classically) integrable quantum mechanical system with two degrees of freedom, the functional dependence $\hat{H}=H_Q(\hat{J}_1,\hat{J}_2)$ of the Hamiltonian operator on the action operators is analyzed and compared with the corresponding functional relationship $H(p_1,q_1;p_2,q_2) = H_C(J_1,J_2)$ in the classical limit of that system. The former is shown to converge toward the latter in some asymptotic regime associated with the classical limit, but the convergence is, in general, non-uniform. The existence of the function $\hat{H}=H_Q(\hat{J}_1,\hat{J}_2)$ in the integrable regime of a parametric quantum system explains empirical results for the dimensionality of manifolds in parameter space on which at least two levels are degenerate. The comparative analysis is carried out for an integrable one-parameter two-spin model. Additional results presented for the (integrable) circular billiard model illuminate the same conclusions from a different angle.

description: Magnetic excitations of the recently discovered frustrated spin-1/2 two-leg ladder system Li$_2$Cu$_2$O(SO$_4$)$_2$ are investigated using inelastic neutron scattering, magnetic susceptibility and infrared absorption measurements. Despite the presence of a magnetic dimerization concomitant with the tetragonal-to-triclinic structural distortion occurring below 125 K, neutron scattering experiments reveal the presence of dispersive triplet excitations above a spin gap of $Δ= 10.6$ meV at 1.5 K, a value consistent with the estimates extracted from magnetic susceptibility. The likely detection of these spin excitations in infrared spectroscopy is explained by invoking a dynamic Dzyaloshinskii-Moriya mechanism in which light is coupled to the dimer singlet-to-triplet transition through an optical phonon. These results are qualitatively explained by exact diagonalization and higher-order perturbation calculations carried out on the basis of the dimerized spin Hamiltonian derived from first-principles.

description: In this paper, our aim is to obtain new fixed-disc results on metric spaces. To do this, we present a new approach using the set of simulation functions and some known fixed-point techniques. We do not need to have some strong conditions such as completeness or compactness of the metric space or continuity of the self-mapping in our results. Taking only one geometric condition, we ensure the existence of a fixed disc of a new type contractive mapping.

description: We investigate the periodic structure formation upon intense femtosecond pulsed irradiation of chrome steel (100Cr6) for linearly polarised laser beams. The underlying physical mechanism of the laser induced periodic structures is explored, their spatial frequency is calculated and theoretical results are compared with experimental observations. The proposed theoretical model comprises estimations of electron excitation, heat transfer, relaxation processes, and hydrodynamics-related mass transport. Simulations describe the sequential formation of sub-wavelength ripples and supra-wavelength grooves. In addition, the influence of the laser wavelength on the periodicity of the structures is discussed. The proposed theoretical investigation offers a systematic methodology towards laser processing of steel surfaces with important applications.

description: Parental involvement is one of the determinants of the academic success of the students. Thus, the COVID-19 pandemic affected the living conditions of societies, specifically, the families. Further, this resulted in the implementation of the new normal of education: online learning modalities. Therefore, it challenges the students with their parents to be active in learning in-home while the isolation is relative to their success in their educational goals. Moreover, the study investigates the relationship between parental involvement and the academic performance of the 493 participants in private schools in the Philippines. The study's statistical analysis resulted in a significant relationship between parental involvement and students' academic performance. Thus, the following conclusions were derived: The parents were still in the process of developing their involvement in school, specifically, in this challenging time. Also, the level of academic performance showed that the mean score of the respondents' academic performance was very satisfactory. This revealed that the students performed well in class during online learning modalities.

description: Revealing what fraction of galaxies harbor AGN is central in understanding black hole accretion history of the Universe. However, optical and soft X-ray surveys miss the most highly obscured AGNs. Infrared (IR), instead, is more robust against absorption. Previous IR photometric surveys, however, only had 4 or 5 filters in mid-IR. Our AKARI North Ecliptic Pole (NEP) wide field sample has 18 filters in mid-IR (9 from AKARI, 4 from WISE, and 5 from Spitzer), for the first time, allowing a sophisticated mid-IR SED fitting diagnosis for a statistical number of sources (89178 over 5.4 deg$^2$). By using a SED fitting technique, we investigate the evolution of AGN fraction as a function of redshift and IR (8-1000 $μ$m) luminosity in an extinction-free way. We found that the AGN fraction (F$_{\rm AGN}$) shows no sign of strong redshift evolution. Instead, F$_{\rm AGN}$ increases with increasing IR luminosity in all redshifts bins ($0

description: Since the largest 2014-2016 Ebola virus disease outbreak in West Africa, understanding of Ebola virus infection has improved, notably the involvement of innate immune mediators. Amongst them, collectins are important players in the antiviral innate immune defense. A screening of Ebola glycoprotein (GP)-collectins interactions revealed the specific interaction of human surfactant protein D (hSP-D), a lectin expressed in lung and liver, two compartments where Ebola was found in vivo. Further analyses have demonstrated an involvement of hSP-D in the enhancement of virus infection in several in vitro models. Similar effects were observed for porcine SP-D (pSP-D). In addition, both hSP-D and pSP-D interacted with Reston virus (RESTV) GP and enhanced pseudoviral infection in pulmonary cells. Thus, our study reveals a novel partner of Ebola GP that may participate to enhance viral spread.

description: The paper treats the issue of the length of a rotating circumference as seen from on board the moving disk and from an inertial reference frame. It is shown that, properly defining a measuring process, the result is in both cases 2piR thus dissolving the Ehrenfest paradox. The same holds good when considering that, for the rotating observer, the perceived radius coincides with the curvature radius of a space-time helix and a complete round trip corresponds to an angle which differs from the one seen by the inertial observer. The apparent contradiction with the Lorentz contraction is discussed.

description: We consider the propagation of a single particle in a random chain, assisted by the coupling to dispersive bosons. Time evolution treated with rate equations for hopping between localized states reveals a qualitative difference between dynamics due to noninteracting bosons and hard-core bosons. In the first case the transient dynamics is subdiffusive, but multi-boson processes allow for long-time normal diffusion, while hard-core effects suppress multi-boson processes leading to persistent subdiffusive transport, consistent with numerical results for a full many-body evolution. In contrast, analogous study for a quasiperiodic potential reveals a stable long-time diffusion.

Transactional and Transformative Corporate Social Responsibility (CSR) Initiatives in the Philippine Education Sector: A Two-Case Study

Year: 2024

CSR Communication
Community Participation

description: With the emergence of the Sustainable Development Goals (SDGs), businesses now incorporate societal development into their operations through Corporate Social Responsibility (CSR) initiatives. However, to prevent "SDG-washing" or superficial use of SDG language for marketing and public relations, it's essential to ensure genuine, relevant, and meaningful impact in addressing societal challenges.

From a development communication perspective, CSR initiatives must create shared value for both the company and the communities involved. Yet, limited research exists on how community participation influences CSR outcomes. This research explored two types of CSRs, transactional and transformational, to understand the nature, characteristics, and communication processes involved in the two approaches.

Using thematic analysis, content analysis, and supporting data from a quantitative survey, the study identified distinct features of each. Transactional CSRs are mostly short-term, targeting business gains with minimal beneficiary involvement, while transformational CSRs are participatory, community- centric, and focused on long-term, sustainable impact aligned with the SDG agenda. Overall, the study highlighted that community participation in CSR initiatives is associated with achieving meaningful and sustainable results in addressing educational challenges. This study contributed to development communication literature by offering actionable insights for CSR practitioners, policymakers, and players seeking to enhance the impact of education-related CSRs.

description: The Maxwell-Chern-Simons gauge theory with charged scalar fields is analyzed at two loop level. The effective potential for the scalar fields is derived in the closed form, and studied both analytically and numerically. It is shown that the U(1) symmetry is spontaneously broken in the massless scalar theory. Dimensional transmutation takes place in the Coleman-Weinberg limit in which the Maxwell term vanishes. We point out the subtlety in defining the pure Chern-Simons scalar electrodynamics and show that the Coleman-Weinberg limit must be taken after renormalization. Renormalization group analysis of the effective potential is also given at two loop.

description: Much of the star formation is obscured by dust. For the complete understanding of the cosmic star formation history (CSFH), infrared (IR) census is indispensable. AKARI carried out deep mid-infrared observations using its continuous 9-band filters in the North Ecliptic Pole (NEP) field (5.4 deg$^2$). This took significant amount of satellite's lifetime, $\sim$10\% of the entire pointed observations. By combining archival Spitzer (5 bands) and WISE (4 bands) mid-IR photometry, we have, in total, 18 band mid-IR photometry, which is the most comprehensive photometric coverage in mid-IR for thousands of galaxies. However previously, we only had shallow optical imaging ($\sim$25.9ABmag) in a small area of 1.0 deg$^2$. As a result, there remained thousands of AKARI's infrared sources undetected in optical. Using the new Hyper Suprime-Cam on Subaru telescope, we obtained deep enough optical images of the entire AKARI NEP field in 5 broad bands ($g\sim$27.5mag). These provided photometric redshift, and thereby IR luminosity for the previously undetected faint AKARI IR sources. Combined with the accurate mid-IR luminosity measurement, we constructed mid-IR LFs, and thereby performed a census of dust-obscured CSFH in the entire AKARI NEP field. We have measured restframe 8$μ$m, 12$μ$m luminosity functions (LFs), and estimated total infrared LFs at 0.35$

description: We report on the discovery of the optical/IR counterpart of the 15.8s transient X-ray pulsar XTE J1946+274. We re-analysed archival BeppoSAX observations of XTE J1946+274, obtaining a new refined position (a circle with 22" radius at 90% confidence level). Based on this new position we carried out optical and infra-red (IR) follow-up observations. Within the new error circle we found a relatively optical faint (B=18.6) IR bright (H=12.1) early type reddened star (V--R=1.6). The optical spectra show strong H-alpha and H-beta emission lines. The IR photometric observations of the field confirm the presence of an IR excess for the H-alpha--emitting star (K=11.6, J--H=0.6) which is likely surrounded by a circumstellar envelope. Spectroscopic and photometric data indicate a B0--1V--IVe spectral-type star located at a distance of 8--10kpc and confirm the Be-star/X-ray binary nature of XTE J1946+274.

Perturbative expansions of the conformation tensor in viscoelastic flows

description: We consider the problem of formulating perturbative expansions of the conformation tensor, which is a positive-definite tensor representing polymer deformation in viscoelastic flows. The classical approach does not explicitly take into account that the perturbed tensor must remain positive definite---a fact that has important physical implications, e.g. extensions and compressions are represented similarly to within a negative sign, when physically the former are unbounded and the latter are bounded from below. Mathematically, the classical approach assumes that the underlying geometry is Euclidean, and this assumption is not satisfied by the manifold of positive definite tensors. We provide an alternative formulation that retains the conveniences of classical perturbation methods used for generating linear and weakly nonlinear expansions, but also provides a clear physical interpretation and a mathematical basis for analysis. The approach is based on treating a perturbation as a sequence of successively smaller deformations of the polymer. Each deformation is modelled explicitly using geodesics on the manifold of positive-definite tensors. Using geodesics, and associated geodesic distances, is the natural way to model perturbations to positive-definite tensors because it is consistent with the manifold geometry. Approximations of the geodesics can then be used to reduce the total deformation to a series expansion in the small perturbation limit. We illustrate our approach using direct numerical simulations of the nonlinear evolution of Tollmien-Schlichting waves.

description: We report on the discovery of a merger-driven starburst at z = 1.52, PACS-787, based on high signal-to-noise ALMA observations. CO(5-4) and continuum emission (850um) at a spatial resolution of 0.3" reveal two compact (r_1/2 ~ 1 kpc) and interacting molecular gas disks at a separation of 8.6 kpc thus indicative of an early stage in a merger. With a SFR of 991 Msun/yr, this starburst event should occur closer to final coalescence, as usually seen in hydrodynamical simulations. From the CO size, inclination, and velocity profile for both disks, the dynamical mass is calculated through a novel method that incorporates a calibration using simulations of galaxy mergers. Based on the dynamical mass, we measure (1) the molecular gas mass, independent from the CO luminosity, (2) the ratio of the total gas mass and the CO(1 - 0) luminosity (alpha_CO = M_gas/L'_CO(1-0)), and (3) the gas-to-dust ratio, with the latter two being lower than typically assumed. We find that the high star formation, triggered in both galaxies, is caused by a set of optimal conditions: a high gas mass/fraction, a short depletion time (t_depl=85 and 67 Myrs) to convert gas into stars, and the interaction of likely counter-rotating molecular disks that may accelerate the loss of angular momentum. The state of interaction is further established by the detection of diffuse CO and continuum emission, tidal debris that bridges the two nuclei and is associated with stellar emission seen by HST/WFC3. This observation demonstrates the power of ALMA to study the dynamics of galaxy mergers at high redshift.

description: A comparative study is performed to explore the periodic structure formation upon intense femtosecond pulsed irradiation of dielectrics with radially and azimuthally polarised beams. Laser conditions have been selected appropriately to produce excited carriers with densities below the optical breakdown threshold in order to highlight the role of phase transitions in surface modification mechanisms. The frequency of the laser induced structures is calculated based on a theoretical model that comprises estimation of electron density excitation, heat transfer, relaxation processes, and hydrodynamics-related mass transport. The influence of the laser wavelength in the periodicity of the structures is also unveiled. The decreased energy absorption for azimuthally polarised beams yields periodic structures with smaller frequencies which are more pronounced as the number of laser pulses applied to the irradiation spot increases. Similar results are obtained for laser pulses of larger photon energy and higher fluences. All induced periodic structures are oriented parallel to the laser beam polarisation.

description: We identify a class of 2+1 dimensional models, involving multiple Chern-Simons gauge fields, in which a form of classical confinement occurs. This confinement is not cumulative, but allows finite mass combinations of individually confined objects, as in baryons. The occurrence and nature of the phenomena depends on number theoretic properties of the couplings and charges.

description: Some types of first integrals for Hamiltonian Nambu-Poisson vector fields are obtained by using the notions of pseudosymmetries. In this theory, the homogeneous Hamiltonian vector fields play a special role and we point out this fact. The differential system which describe the $SU(2)$-monopoles is given as example. The paper ends with two appendices.

description: We present near-infrared color-magnitude diagrams for the LMC star clusters Hodge 4 and NGC 1651 revealing the helium burning red clump stars for the first time in the JK passbands. From these diagrams, which extend to K~19, and existing optical CMDs that reveal the clusters' main sequence turnoffs, we determine the following cluster parameters. For Hodge 4, we estimate a metallicity of [Fe/H] = -0.17 +/- 0.04, an age of 1.7 +/- 0.3 Gyr, and a red clump absolute magnitude of Mk(RC) = -1.64 +/- 0.17. Along with an adopted reddening of E(J-K) = 0.03 +/- 0.01 based on the Burstein & Heiles and Schlegel et al. reddening maps, we find a distance of (m-M)o = 18.52 +/- 0.17 for Hodge 4. In the case of NGC 1651, we derive [Fe/H] = -0.07 +/- 0.10, an age of 1.8 +/- 0.3 Gyr, Mk(RC) = -1.56 +/- 0.12, E(J-K) = 0.06 +/- 0.01, and (m-M)o =18.55 +/- 0.12, all measured in the same manner as for Hodge 4. Based on these two clusters, we calculate a mean LMC distance of (m-M)o = 18.54 +/- 0.10.

description: We present an analysis of the molecular gas properties, based on CO(2 - 1) emission, of twelve starburst galaxies at z~1.6 selected by having a boost (>~4x) in their star formation rate (SFR) above the average star-forming galaxy at an equivalent stellar mass. ALMA observations are acquired of six additional galaxies than previously reported through our effort. As a result of the larger statistical sample, we significantly detect, for the first time at high-z, a systematically lower L'_CO/L_IR ratio in galaxies lying above the star-forming `main sequence' (MS). Based on an estimate of alpha_CO (i.e., the ratio of molecular gas mass to L'_CO(1-0)), we convert the observational quantities (e.g., L'_CO/L_IR) to physical units (M_gas/SFR) that represent the gas depletion time or its inverse, the star formation efficiency. We interpret the results as indicative of the star formation efficiency increasing in a continuous fashion from the MS to the starburst regime, whereas the gas fractions remain comparable to those of MS galaxies. Although, the balance between an increase in star-formation efficiency or gas fraction depends on the adopted value of alpha_CO as discussed.

description: Recently\cite{BQG}, it was shown that quantum effects of matter could be identified with the conformal degree of freedom of the space-time metric. Accordingly, one can introduce quantum effects either by making a scale transformation (i.e. changing the metric), or by making a conformal transformation (i.e. changing all physical quantities). These two ways are investigated and compared. Also, it is argued that, the ultimate formulation of such a quantum gravity theory should be in the framework of the scalar-tensor theories.

description: We show that collective dynamics of a curved domain wall in a (3+1)-dimensional relativistic scalar field model is represented by Nambu-Goto membrane and (2+1)-dimensional scalar fields defined on the worldsheet of the membrane. Our argument is based on a recently proposed by us version of the expansion in the width. Derivation of the expansion is significantly reformulated for the present purpose. Third and fourth order corrections to the domain wall solution are considered. We also derive an equation of motion for the core of the domain wall. Without the (2+1)-dimensional scalar fields this equation would be nonlocal.

Collective states in nuclei and many-body random interactions

description: Low-lying collective states in nuclei are investigated in the framework of the interacting boson model using an ensemble of random many-body interactions. It is shown that whenever the number of bosons is sufficiently large compared to the rank of the interactions, the spectral properties are characterized by a dominance of L(P)=0(+) ground states and the occurrence of both vibrational and rotational band structures. This indicates that these features represent a general and robust property of the collective model space.

The Transcultural Production of Creative Subjectivity: London Art, Design and Communication Higher Education in Mumbai and Shanghai Cultural Industries
Creators: name: Waldron, Rupert
Publisher: name: University of Westminster
Year: 2025

description: This thesis considers the productive subjectivity of alums of London art and design higher education now active in Mumbai and Shanghai cultural industries, drawing on interviews with 51 practitioners. It proposes a framework emphasising the dialectical roots of Leon Trotsky’s concept of uneven and combined development in Hegelian dialectics to study creative labour in transnational capitalism. I argue that the production of creative subjectivity emerges from uneven and combined development through learned processes of internalisation and externalisation. Internationally mobile subjects from the southern cities engage in a passage through the constitutive other – the former metropole – to produce a subjectivity whose very autonomy and abstractly cosmopolitan flexibility serves transnational capital.

The research finds that interview subjects utilise discourses of non-contemporaneous world space and learned forms of creativity as the managed development of the potentialities of disjuncture. Participants identify with the project of helping to bring the southern cities into self-contemporaneity through their productive intervention. They thereby engage with the unevenness of world space under the international division of labour in subjective terms as a source of creative potential from difference. Objective factors of unevenness highlighted by participants include differential degrees of commodification and division of labour, skills levels, and predominance of mental over manual labour, but also factors associated with less capitalistically developed means of labour reproduction in the Southern cities as compared to London, such as universities, museums and galleries, and consumer culture such as fashion. These inform subjective discourses of individual and national becoming.

I address the production of world space as the distribution of fragmented subjectivity according to the conflicting needs of capital and labour. Educational migrants to and from the command centres of capital re-internalise the force of fragmentation as productive self-development, mapping individual yearnings to capital’s needs for expansion. I show that creative labour, while harbouring emancipatory potentials, is, under existing conditions, characterised by active alienation: the ongoing extension of the rule of dead over living labour.

Death and burial at Port Arthur, 1830-1877
Creators: name: Ross, L
Publisher: name: University of Tasmania
Year: 2023

description: This thesis examines the subject of death and burial at Port Arthur by testing assertions used in current interpretation of the graveyard, the Isle of the Dead. The issues addressed relate to who was buried there, how many, causes of death and methods of interment. In order to fulfill the aims, relevant death and burial registers were transcribed and compiled on to a database. It has been demonstrated that the number of dead believed to be on the island was too high and an alternative figure is suggested. Those in unmarked graves were found to be not just convicts but a mixture of convict, pauper, invalid and lunatic, thus illustrating the complexity of function of this penal settlement. Indeed, the pattern of burial mirrors the transitional stages of Port Arthur's development, as well as social attitudes of the age.
