description: We study the emergence over time of a universal, uniform distribution of quantum states supported on a finite subsystem, induced by projectively measuring the rest of the system. Dubbed deep thermalization, this phenomenon represents a form of equilibration in quantum many-body systems stronger than regular thermalization, which only constrains the ensemble-averaged values of observables. While there exist quantum circuit models of dynamics in one dimension where this phenomenon can be shown to arise exactly, these are special in that deep thermalization occurs at precisely the same time as regular thermalization. Here, we present an exactly-solvable model of chaotic dynamics where the two processes can be shown to occur over different time scales. The model is composed of a finite subsystem coupled to an infinite random-matrix bath through a small constriction, and highlights the role of locality and imperfect thermalization in constraining the formation of such universal wavefunction distributions. We test our analytical predictions against exact numerical simulations, finding excellent agreement.

description: We present direct detection constraints on the absorption of hidden-photon dark matter with particle masses in the range 1.2-30 eV$c^{-2}$ with the DAMIC experiment at SNOLAB. Under the assumption that the local dark matter is entirely constituted of hidden photons, the sensitivity to the kinetic mixing parameter $κ$ is competitive with constraints from solar emission, reaching a minimum value of 2.2$\times$$10^{-14}$ at 17 eV$c^{-2}$. These results are the most stringent direct detection constraints on hidden-photon dark matter in the galactic halo with masses 3-12 eV$c^{-2}$ and the first demonstration of direct experimental sensitivity to ionization signals $

description: Hotspots observed at the edges of extended radio lobes in high-power radio galaxies and quasars mark the position of mildly-relativistic termination shock, where the jet bulk kinetic energy is converted to the internal energy of the jet particles. These are the only astrophysical systems where mildly-relativistic shocks can be directly resolved at various wavelengths of the electromagnetic spectrum. The western hotspot in the radio galaxy Pictor\,A is an exceptionally good target in this respect, due to the combination of its angular size and high surface brightness. In our previous work, after a careful {\it Chandra} image deconvolution, we resolved this hotspot into a disk-like feature perpendicular to the jet axis, and identified this as the front of the jet termination shock. We argued for a synchrotron origin of the observed X-ray photons, which implied maximum electron energies of the order of 10--100\,TeV. Here we present a follow-up on that analysis, proposing in particular a novel method for constraining the shape of the X-ray continuum emission with sub-arcsec resolution. The method is based on a {\it Chandra} hardness map analysis, using separately de-convolved maps in the soft and hard X-ray bands. In this way, we have found there is a systematic, yet statistically significant gradient in the hardness ratio across the shock, such that the implied electron energy index ranges from $s\leq 2.2$ at the shock front to $s> 2.7$ in the near downstream. We discuss the implications of the obtained results for a general understanding of particle acceleration at mildly-relativistic shocks.

description: Although proper safety management in construction is of utmost importance; evidence suggests that safety is not adequately considered in many developing countries. Hence, the objective of this study was to assess safety practice in road construction projects in the city of Addis Ababa. Questionnaire survey was used to collect data on safety practice in Addis Ababa road construction projects. A total of 83 questionnaires were distributed in three projects that were run by local Contactor, Chinese Contractor and own force project (the client act as both client and contractor and 83 responses were received. The data was analyzed using quantitatively descriptive statistics Microsoft Excel & SPSS. Consequently, the study result revealed that the safety practices of Addis Ababa road construction projects are not up to expectation. The constraints in implementing construction safety in Addis Ababa road construction projects are lack of personal protective equipment's, lack of top management commitment in safety programs, insufficient safety budget, lack of safety supervisor on site and ineffectiveness of current safety policies are the top five. Falling in to excavated pit, falling in to hot asphalt(leg or hand burn), falling from scaffolding, nail piercing, car/truck overturning, hit by equipment's/machinery, rock/ soil slide is and machinery accidents in loading and unloading are frequently occurring accidents that respondents identified in Addis Ababa road construction projects. Hazardous procedures, on or around machines or equipment's, unavailability of PPE; inappropriate PPE design, improperly guarded areas, lack of safety plan/ risk identification, lack of safety training/ lack of awareness and ineffectiveness of current safety policy are the contributing factors to the occurrence of accidents on the road construction sites in Addis Ababa

title: What are practitioners' understanding and perceptions of extrinsic motivation, how is it used with children in the foundation stage and what are its perceived effects on their learning and well-being?
Creators: name: Virdi, Sheralee Lorna
Publisher: name: University of Reading
Year: 2023

description: The focus of this thesis is to explore what are early years practitioners’ understanding and perceptions of extrinsic motivation, how it is used with children and what are the perceived effects on their learning and well-being? Very little research exists that investigates practitioners’ understanding in relation to this area, as well as their perceptions and viewpoints, both professionally and personally. This study seeks to explore this area further and to gain an insight into practitioners’ thoughts about the effects of extrinsic motivation on children’s learning and well-being. Specifically, the study focuses on exploring the techniques that practitioners use to motivate children, if any; to understand why practitioners use the techniques they do, exploring their perception of the advantages and disadvantages; to identify what training practitioners receive to support their understanding in relation to motivating children. The research uses a mixed methods approach and an interpretive paradigm to understand practitioners’ views in depth, through conducting an online questionnaire survey (Appendix C) and interviews (Appendix D) within practitioners’ schools. The focus is on investigating the rewards systems, policies, training and practitioners’ thoughts on the advantages and disadvantages of using these techniques. The sample included a selection of 33 foundation stage leaders, teachers, higher level teaching assistants and teaching assistants. The study’s methods were shown to be effective in collating data to address the research questions. The findings from the study were mixed. Some practitioners were in favour of using extrinsic motivational methods in the classroom, with 30 of the 33 citing that it supported self-regulation and motivated the children in their learning. However, other practitioners, 9 of the 33 thought that the rewards used in the foundation stage to motivate children extrinsically were meaningless, inconsistent and had no overall longevity. The study provides interesting insight into practitioners’ views of extrinsic motivation and has enabled the research to shed some light on and inform the literature in this area. Some recommendations for practice and ideas for future research are also offered at the end of the thesis.

Remarkably, with consequently increasing edge velocity, the edge conductance at zero and applied magnetic fields manifests time reversal symmetry (TRS) -protected properties consistent with Z2 topological insulator. The InAs/GaInSb bilayers offer a much sought-after platform for future studies and applications of the QSHI.

description: Scattering angles for probes in Kerr metrics are derived for scattering in the equatorial plane of the black hole. We use a method that naturally resums all orders in the spin of the Kerr black hole, thus facilitating comparisons with scattering-angle computations based on the Post-Minkowskian expansion from scattering amplitudes or worldline calculations. We extend these results to spinning black-hole probes up to and including second order in the probe spin and any order in the Post- Minkowskian expansion, for probe spins aligned with the Kerr spin. When truncating to third Post-Minkowskian order, our results agree with those obtained by amplitude and worldline methods.

description: Members of family Actinobacteria, especially the genus Streptomyces have demonstrated exemplary performance in synthesizing bioactive compounds. By investigating various properties of the bacteria, the current study has identified four novel Streptomyces species from the poorly explored mangrove sediment in the east coast of Peninsular Malaysia. Among the four strains, extract of MUSC 136T showed highest toxicity towards colon cancer cells, probably triggering cell death via altering components of important pathways like p53 protein and intracellular glutathione levels. Altogether, these findings suggested that the exploration of new streptomycetes from underexplored area is a good strategy to discover useful bioactive compounds.

description: Background: Low energy $β$ and electron capture (EC) decays are important systems in neutrino mass determination experiments. An isotope with an ultra-low Q value $β$-decay to an excited state in the daughter with Qes < 1 keV could provide a promising alternative candidate for future experiments. $^{75}$Se EC and $^{75}$Ge $β$-decay represent such candidates, but a more precise determination of the mass of the common daughter, $^{75}$As, is required to evaluate whether their potential decay branches are energetically allowed and ultra-low. Purpose: Perform a precise atomic mass measurement of $^{75}$As and combine the result with the precisely known atomic masses of $^{75}$Se and $^{75}$Ge, along with nuclear energy level data for $^{75}$As to evaluate potential ultra-low Q value decay branches in the EC decay of $^{75}$Se and the $β$-decay of $^{75}$Ge. Method: The LEBIT Penning trap mass spectrometer at the Facility for Rare Isotope Beams was used to perform a high-precision measurement of the atomic mass of $^{75}$As via cyclotron frequency ratio measurements of $^{75}$As$^{+}$ to a $^{12}$C$_{6}^{+}$ reference ion. Results: The $^{75}$As mass excess was determined to be ME($^{75}$As)= -73 035.98(43) keV, from which the ground-state to ground-state Q values for $^{75}$Se EC and $^{75}$Ge $β$-decay were determined to be 866.50(44) keV and 1179.01(44) keV, respectively. These results were compared to energies of excited states in $^{75}$As at 865.4(5) keV and 1172.0(6) keV to determine Q values of 1.1(7) keV and 7.0(7) keV for the potential ultra-low EC and $β$-decay branches of $^{75}$Se and $^{75}$Ge, respectively. Conclusion: The $^{75}$Se EC decay to the 865.4 keV excited state in $^{75}$As is potentially ultra-low with Qes $\approx$ 1 keV. However, a more precise determination of the 865.4(5) keV level in $^{75}$As is required.

description: This is the Supporting Information for Dröllner et al. "Directly dating Plio-Pleistocene climate change in the terrestrial record" published in Geophysical Research Letters. The data comes from a ferruginous induration in the arid landscapes of the Nullarbor Plain in southern Australia (30° 54' 33.84'' S, 132° 13' 5.88'' E). The data provides constraints on the timing of Plio-Pleistocene aridification in the continental realm and supports the use of ferruginous indurations as targets to obtain absolute ages on landscape evolution. The dataset includes chemical-mineralogical results, which suggest that the formation of ferruginous indurations was linked with a decline of the groundwater table. (U-Th)/He geochronology of goethite from ferruginous indurations provides age constraints that link the textural and chemical-mineralogical observations to a rapid climatic shift from humid Late Pliocene to arid Early Pleistocene conditions. Specifically, this Supporting Information includes a pdf file (available through Zenodo; https://doi.org/10.5281/zenodo.7739575) with detailed analytical methods for X-ray powder diffraction (XRD, Text S1), energy-dispersive spectroscopy (Text S2), Raman spectroscopy (Text S3), and (U-Th)/He geochronology (Text S4). This pdf file also includes Supporting Figures S1 (sample material, and fragments used for dating) and S2 (XRD spectra), as well as Supporting Tables S1 (XRD bulk mineralogy), S2 ((U-Th)/He data), S3 (XRD instrument parameters), and the captions for Table S4 (Raman data) and Table S5 (XRD data).

description: The detection of stochastic gravitational wave background (SGWB) is among the leading scientific goals of the space-borne gravitational wave observatory, which would have significant impact on astrophysics and fundamental physics. In this work, we developed a data analysis software, \texttt{TQSGWB}, which can extract isotropic SGWB using the Bayes analysis method based on the TianQin detector. We find that for the noise cross spectrum, there are imaginary components and they play an important role in breaking the degeneracy of the position noise in the common laser link. When the imaginary corrections are considered, the credible regions of the position noise parameters are reduced by two orders of magnitude. We demonstrate that the parameters of various signals and instrumental noise could be estimated directly in the absence of a Galactic confusion foreground through Markov chain Monte Carlo sampling. With only a three-month observation, we find that TianQin could be able to confidently detect SGWBs with energy density as low as $Ω_{\rm PL} = 1.3 \times 10^{-12}$, $Ω_{\rm Flat} = 6.0 \times 10^{-12}$, and $Ω_{\rm SP} = 9.0 \times 10^{-12}$, for power-law, flat, and single-peak models respectively.

description: We analyse the multiscale properties of energy-conserving upwind-stabilised finite element discretisations of the two-dimensional incompressible Euler equations. We focus our attention on two particular methods: the Lie derivative discretisation introduced in Natale and Cotter (2016a) and the Streamline Upwind/Petrov-Galerkin (SUPG) discretisation of the vorticity advection equation. Such discretisations provide control on enstrophy by modelling different types of scale interactions. We quantify the performance of the schemes in reproducing the non-local energy backscatter that characterises two-dimensional turbulent flows.
Investigating the Mentalization-based Developmental Model of Borderline Pathology in Adolescents

description: Mentalization, i.e., the capacity for perspective-taking/reflection on one’s own and others’ mental states, is proposed to play a crucial role in the disturbed interpersonal-relatedness that is a hallmark of borderline personality disorder (BPD). Despite growing evidence of BPD in adolescents, studies examining mentalization in relation to adolescent BPD are limited. This thesis addresses this gap by providing further examination of this model of BPD in adolescence. Findings provide a clearer understanding about the nature of mentalizing difficulties in adolescents with BPD. They also clarify specific developmental pathways toward BPD, and provide further direct support for a mentalization-based model of BPD.
Assessment Of Project Management Maturity At The Ministry Of Urban Development And Construction –The Case Of The Federal Government Buildings Construction Project Office

Year: 2019

description: The research was carried out to determine the project management maturity level of the Federal Government Buildings Construction Project Office and identify its weakness and strengths. Primary data were collected using survey questionnaire and unstructured interviews with the selected members of the project office. The PM Solutions' project management maturity model is used to level the maturity of the project management of the office. Based on the findings, the Project Office's project management maturity level is identified to be level 2 which indicate that the basic project management processes and documentation exist in the project office, but they are not considered as an organizational standard. There are basic metrics to track project cost, schedule, and technical performance. The office lacks project management professionals and training opportunities are limited. Management supports the implementation of project management, but there is neither consistent understanding, involvement, nor the organizational mandate to comply for all projects. With this consideration, it is recommended that the project office needs to make more efforts to enhance its maturity level by establishing tailorable organizational standards and institutionalized processes for all project management processes. The project office needs to be equipped with project management professionals and consistent trainings in project management knowledge areas and their application must be provided to project team members. Continuous improvement based on lesson learned needs to be encouraged. In addition, improving management oversight, integrating project management processes, ensuring the establishment of effective risk management standards and project quality assurance mechanisms, and implementing all-inclusive monitoring and evaluation system are necessary.

description: Nonlinear isolated and coupled oscillators are extensively studied as prototypical nonlinear dynamics models. Much attention has been devoted to oscillator synchronization or the lack thereof. Here, we study the synchronization and stability of coupled driven-damped Helmholtz-Duffing oscillators in bi-stability regimes. We find that despite the fact that the system parameters and the driving force are identical, the stability of the two states to spatially non-uniform perturbations is very different. Moreover, the final stable states, resulting from these spatial perturbations, are not solely dictated by the wavelength of the perturbing mode and take different spatial configurations in terms of the coupled oscillator phases.

description: Madagascar’s high rates of endemism, paired with its escalating deforestation rates, has made it one of the most important conservation priorities on the planet. In southeastern Madagascar, the Corridor Forestier d'Ambositra Vondrozo (COFAV) is an unprotected rainforest corridor that sustains ~15 species of lemurs, most of which are endangered. The COFAV connects many protected areas and is therefore essential for gene flow, dispersal, and the long-term sustainability of animal populations in the area. The corridor has not been surveyed extensively since the 90’s, and even so, only a fraction of the sites have been sampled multiple times. The goal of our study was to survey the COFAV, from Ranomafana National Park to the Mananara River, to provide updated species occurrences and ranges. Combining data across multiple teams using different inventorying methods, we surveyed a total area of 227km2 throughout an eight-month period. We recorded every lemur occurrence (sighting or vocalization) and noted the species, date, time, group size, and GPS coordinates. We found 11 lemur species and one putative hybrid species. The geographic ranges for three species (Hapalemur aureus, H. griseus, Propithecus edwardsi) were larger than previously thought. The range of Varecia variegata should be shortened and adjusted accordingly, as the species appears transient (at best) in the northern parts of Ranomafana National Park and was not found south of the Ambohimahamasina/Ikongo region. This study provides updated geographic ranges for lemur species in the COFAV, important information for future censuses, species assessments, and conservation measures for future implementation.

description: Rooted in group field theory and matrix models, random tensor models are a recent background-invariant approach to quantum gravity in arbitrary dimensions. Colored tensor models (CTM) generate random triangulated orientable (pseudo)-manifolds. We analyze, in low dimensions, which known spaces are triangulated by specific CTM interactions. As a tool, we develop the graph-encoded surgery that is compatible with the structure of quantum field theory and use it to prove that a single model, the complex $φ^4$-interaction in rank-$2$, generates all orientable $2$-bordisms, thus, in particular, also all orientable, closed surfaces. We show that certain quartic rank-$3$ CTM, the $φ_3^4$-theory, has as boundary sector all closed, possibly disconnected, orientable surfaces. Hence all closed orientable surfaces are cobordant via manifolds generated by the $φ_3^4$-theory.

description: A discrete quantum spin system is presented in which several modern methods of canonical quantum gravity can be tested with promising results. In particular, features of interacting dynamics are analyzed with an emphasis on homogeneous configurations and the dynamical building-up and stability of long-range correlations. Different types of homogeneous minisuperspace models are introduced for the system, including one based on condensate states, and shown to capture different aspects of the discrete system. They are evaluated with effective methods and by means of continuum limits, showing good agreement with operator calculations whenever the latter are available. As a possibly quite general result, it is concluded that an analysis of the building-up of long-range correlations in discrete systems requires non-perturbative solutions of the dynamical equations. Some questions related to stability can be analyzed perturbatively, but suggest that matter couplings may be relevant for this question in the context of quantum cosmology.

The effect of Organizational Culture on Project Management performance: The case of Ethio Telecom
Creators: name: Getachew, Dawit
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Ethio Telecom had been embarking on programs worth of Billions of dollars in the past 10 years, and becomes mind taking to pay attention of what unique culture might be drawn of Ethio Telecom and how that very culture affected the project management performance of programs or the projects with in the programs. Accordingly, the primary objective of the study was to assess organizational culture of Ethio Telecom and reflection of these culture on Project Management Performance. Clan, Adhocracy, Hierarchy, and Market were taken as main elements of organizational culture to study the reflection of these cultures on Project Management Performance. The methodology to conduct the research was based on interview and questionaries' for the primary data, and documents from Ethio Telecom and research papers for the secondary data. The study uses Exploratory Sequential Mixed Method (QUAL -> quan ) design in determining relationship between the different types of Organizational Culture and Project Management Performance. Data collected from interview were used as a guideline to develop questionnaire instrument and data from questionnaire response were analyzed with the help of descriptive method of data analysis using statistical software (SPSS)V20. Results shows that Ethio Telecom owns elements of organizational cultures that belongs to all the four main categories of organizational culture (Clan, Adhocracy, Hierarchy and Market) and determined to have relation to the organizations' project management performance KPIs. The outcome of this work will serve Ethio Telecom to evaluate its current organizational culture and make possible move towards its improvement. Since the mean average of all forms of cultures were slightly above average, recommendations are drawn to strengthen the currently available organizational culture through the establishment of responsible work unit for the better of the organizations' project management performance

description: The production of the $K_S^0$ meson in high multiplicity $pp$ collisions at $\sqrt{s} =$ 13 TeV is investigated considering the hybrid formalism and the solution of the running coupling Balitsky - Kovchegov equation. The associated cross section is estimated and compared with the experimental data for the transverse momentum spectrum. Moreover, we analyze the self-normalized yields of $K_S^0$ mesons as a function of the multiplicity of coproduced charged hadrons and demonstrate that a steep increasing is theoretically predicted. A comparison with the ALICE data is presented considering two distinct solutions of the BK equation.

Charged-particle nuclear modification factors in PbPb and pPb collisions at sqrt(s[NN]) = 5.02 TeV

Subjects: subject: Nuclear Experiment (nucl-ex)

description: The spectra of charged particles produced within the pseudorapidity window abs(eta) < 1 at sqrt(s[NN]) = 5.02 TeV are measured using 404 inverse microbarns of PbPb and 27.4 inverse picobarns of pp data collected by the CMS detector at the LHC in 2015. The spectra are presented over the transverse momentum ranges spanning 0.5 < pt < 400 GeV in pp and 0.7 < pt < 400 GeV in PbPb collisions. The corresponding nuclear modification factor, R[AA], is measured in bins of collision centrality. The R[AA] in the 5% most central collisions shows a maximal suppression by a factor of 7-8 in the pt region of 6-9 GeV. This dip is followed by an increase, which continues up to the highest pt measured, and approaches unity in the vicinity of pt = 200 GeV. The R[AA] is compared to theoretical predictions and earlier experimental results at lower collision energies. The newly measured pp spectrum is combined with the pPb spectrum previously published by the CMS Collaboration to construct the pPb nuclear modification factor, R[pA], up to 120 GeV. For pt > 20 GeV, R[pA] exhibits weak momentum dependence and shows a moderate enhancement above unity.

description: Accreting pulsars power relativistic jets, and display a complex spin phenomenology. These behaviours may be closely related to the large-scale configuration of the star's magnetic field, shaped by its interaction with the surrounding accretion disc. Here we present the first relativistic simulations of the interaction of a pulsar magnetosphere with an accretion flow. Our axisymmetric simulations treat the magnetospheric, or coronal, regions using a resistive extension of force-free electrodynamics. The magnetic field is also evolved inside the disc, which is a defined volume with a specified velocity field and conductivity profile, found using an alpha-disc model. We study a range of disc alpha-parameters, thicknesses, magnetic Prandtl numbers, and inner truncation radii. We find that a large fraction of the magnetic flux in the pulsar's closed zone is opened by the intrusion of the disc, leading to an enhancement of the power extracted by the pulsar wind and the spin-down torque applied to the pulsar. In our simulations, most of the spin-down contribution to the stellar torque acts on open field lines. The efficiency of field-line opening is high in the simulations' long-term quasi-steady states, which implies that a millisecond pulsar's electromagnetic wind could be strong enough to power the observed neutron-star radio jets, and may significantly affect the pulsar's spin evolution.

description: This thesis investigates what is learned with the visual perceptual learning (VPL) of face identity, and where face identity VPL occurs within the brain. The first study investigated what is learned at a subjective level, and found that conscious knowledge accessibility was not improved by face identity VPL. The second study investigated what is learned at an objective level, and found that task-relevant facial dimensions was not learned with face identity VPL. The final study investigated where face identity VPL occurs in the brain, and found that the right occipital face area is not causally involved in its early consolidation.
