description: This paper presents the network load balancing problem, a challenging real-world task for multi-agent reinforcement learning (MARL) methods. Traditional heuristic solutions like Weighted-Cost Multi-Path (WCMP) and Local Shortest Queue (LSQ) are less flexible to the changing workload distributions and arrival rates, with a poor balance among multiple load balancers. The cooperative network load balancing task is formulated as a Dec-POMDP problem, which naturally induces the MARL methods. To bridge the reality gap for applying learning-based methods, all methods are directly trained and evaluated on an emulation system from moderate-to large-scale. Experiments on realistic testbeds show that the independent and "selfish" load balancing strategies are not necessarily the globally optimal ones, while the proposed MARL solution has a superior performance over different realistic settings. Additionally, the potential difficulties of MARL methods for network load balancing are analysed, which helps to draw the attention of the learning and network communities to such challenges.

description: Differentiable simulators promise faster computation time for reinforcement learning by replacing zeroth-order gradient estimates of a stochastic objective with an estimate based on first-order gradients. However, it is yet unclear what factors decide the performance of the two estimators on complex landscapes that involve long-horizon planning and control on physical systems, despite the crucial relevance of this question for the utility of differentiable simulators. We show that characteristics of certain physical systems, such as stiffness or discontinuities, may compromise the efficacy of the first-order estimator, and analyze this phenomenon through the lens of bias and variance. We additionally propose an $α$-order gradient estimator, with $α\in [0,1]$, which correctly utilizes exact gradients to combine the efficiency of first-order estimates with the robustness of zero-order methods. We demonstrate the pitfalls of traditional estimators and the advantages of the $α$-order estimator on some numerical examples.

description: We classify line nodes in superconductors with strong spin-orbit interactions and time-reversal symmetry, where the latter may include non-primitive translations in the magnetic Brillouin zone to account for coexistence with antiferromagnetic order. We find four possible combinations of irreducible representations of the order parameter on high symmetry planes, two of which allow for line nodes in pseudo-spin triplet pairs and two that exclude conventional fully gapped pseudo-spin singlet pairs. We show that the former can only be realized in the presence of band-sticking degeneracies, and verify their topological stability using arguments based on Clifford algebra extensions. Our classification exhausts all possible symmetry protected line nodes in the presence of spin-orbit coupling and a (generalized) time-reversal symmetry. Implications for existing non-symmorphic and antiferromagnetic superconductors are discussed.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The purpose of this study was to examine the effects of selected human resource management practices on organizational performance at Berhan Bank S.C. Explicitly, the study attempts to discover the effect of selective hiring, training and development, compensation, performance appraisal and management, self-managed teams and employee involvement. It was carried out in Berhan Bank S.Co. head office and branches in Addis Ababa. Employees from all ranges of positions are included in the sample. Sampling was decided using a formula developed by Kerjice and Morgan to select a sample size of 346 employees from the head office and branches in Addis Ababa. Both descriptive and inferential statistical techniques were used to analyze the data. A step wise multiple regression analysis was conducted to test how well the selected human resource management practices could explain organizational performance. The research finding shows that selected human resource management practices affect organizational performance positively. Compensation, performance appraisal and management and employee involvement variables are identified by a regression analysis as independent variables that have greater power to explain the relationship and influence on organizational performance of the Bank. Finally, the study recommended that, the Bank should adopt a performance appraisal and management system that encourages regular feedback giving, constructive and growth. The Bank should encourage decentralized decisions making and service quality improvements. The Bank should incorporate more reliable decisions on the planning process in HRM matters and implementation of associating program to increase management awareness and employee's involvement. On the top of that, the Bank should focus on the proper implementation of HRM practices level in all its branches and organs towards the appropriate HRM practices
A contract theory approach to Islamic financial securities

description: Submission note: A thesis submitted in total fulfilment of the requirements for Doctor of Philosophy (Finance) to the College of Arts, Social Sciences and Commerce, La Trobe Business School, Department of Economics and Finance, La Trobe University, Victoria.

The aim of this thesis is to investigate the economic and financial substance of certain contractual requirements imposed by Islamic commercial law as well as some of their implications. More attention is given to requirements that have financial implications and are related to those discussed in the contract theory literature. We divide our investigation into four parts. The first part is an examination of the fundamental transactional requirements in Islamic commercial law, focusing on those related to four primary Islamic Financial Securities (IFSs). In the second part, we use our findings to construct an alternative asset pricing methodology. We also explore our findings in the third and fourth parts using the principal-agent model of Holmström and Milgrom (1991). More specifically, we use it to respectively model the relationship between underwriters and Islamic commercial law regulators as well as consider the case of ambiguous incentive contracts. Each part of our investigation has yielded substantial contributions to the literature as follows. Firstly, our examination of Islamic commercial law principles and contracts reveals that there are indeed legal requirements which have direct implications for financial models, such as the need for a liquidity discount in receivables-based ṣukūk as they are – in principle – non-tradeable. Secondly, the asset-pricing model we have constructed allows us to examine the equilibrium return and investment levels of IFSs. This allows us to derive conditions at which one security yields higher returns than another. Thirdly, our cooperation model suggests that cooperation between underwriters and Islamic commercial law regulators is only beneficial for an issuer of a structured Islamic financial product if their synergy benefits are over a certain level. Lastly, our investigation into ambiguous incentive contracts demonstrates that it is never beneficial for principals to offer such contracts to ambiguity averse individuals as it unambiguously reduces the principal’s profit.

Bei näherer Betrachtung seiner Innenraumdarstellungen wird deutlich, dass davon eine ganz besondere Stimmung und Eigentümlichkeit ausgeht, die anhand ausgewählter Werke mittels umfangreicher Bildanalysen herausgearbeitet wird. Die Untersuchung zielt darauf ab, die anwesende Abwesenheit, die all seinen Werken zugrunde liegt, eingehend zu behandeln und dieser auf den Grund zu gehen. Im Zuge dessen werden auch weitere Polaritäten wie innen – außen, Weiblichkeit – Männlichkeit, Sichtbarkeit – Unsichtbarkeit und Fülle – Leere in Vrels Interieurs erörtert. Da ein*e Künstler*in nie isoliert betrachtet werden kann, werden zur Untersuchung auch weitere zeitgenössische niederländische Innenraummaler*innen herangezogen, um aufzuzeigen, dass sich Vrel sehr wohl mit gängigen Themen und Phänomenen seiner Zeit auseinandersetzte, wie unter anderem der aufkommenden Häuslichkeit, der Konstruktion von Raum oder dem Fenster als Schwelle, jedoch seinen eigenen besonderen Weg fand, dies in seiner Malerei umzusetzen.

description: We give estimates of the critical parameter for random loop models that are related to quantum spin systems. A special case of the model that we consider is the interchange- or random-stirring process. We consider here the model defined on regular trees of large degrees, which are expected to approximate high spatial dimensions. We find a critical parameter that indeed shares similarity with existing numerical results for the cubic lattice. In the case of the interchange process our results improve on earlier work by Angel and by Hammond, in that we determine the second-order term of the critical parameter.

Sala, "Quantization of continuum Kac-Moody algebras", Pure Appl. Math. Q. 16 (2020), no. 3, 439-493], we prove that a suitable formulation of the Quantum Duality Principle holds true, both in a "formal" version - i.e., applying to the original definition of U_h(g_X) as a formal QUEA over the algebra of formal series in h - and in a "polynomial" one - i.e., for a suitable polynomial form of U_h(g_X) over the algebra of Laurent polynomials in q. In both cases, the QDP states that a suitable subalgebra of the given quantization of the Lie bialgebra g_X is in fact a suitable quantization (in formal or in polynomial sense) of a connected Poisson group G^*_X dual to g_X .

Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: Preventing obesity is an international health priority. However, few prevention programs have been conducted and of those very few have included a formal comprehensive community evaluation. This thesis describes the design of a multi-level evaluation with application to a large weight gain prevention program, which aims to prevent weight gain in women living in rural Victorian communities. The embedded mixed-methods evaluation was guided by the RE-AIM framework (Reach, Efficacy, Adoption, Implementation and Maintenance), generating new knowledge in program implementation practices and processes, across stakeholders, researchers and consumers. This thesis advances knowledge through the identification of strategies to optimise prevention program implementation and informs scale-up to improve population health outcomes.
Superconductivity without hole-pocket in electron-doped FeSe: Analysis beyond the Migdal-Eliashberg formalism

description: High-Tc pairing mechanism absent of hole-pockets in heavily electron-doped FeSe is one of the key unsolved problems in Fe-based superconductors. Here, this problem is attacked by focusing on the higher-order many-body effects neglected in conventional Migdal-Eliashberg formalism. We uncover two significant many-body effects for high-Tc superconductivity: (i) Due to the "vertex correction", the dressed multiorbital Coulomb interaction acquires prominent orbital dependence for low-energy electrons. The dressed Coulomb interaction not only induces the orbital fluctuations, but also magnifies the electron-boson coupling constant. Therefore, moderate orbital fluctuations give strong attractive pairing interaction. (ii) The "multi-fluctuation-exchange pairing process" causes large inter-pocket attractive force, which is as important as usual single-fluctuation-exchange process. Due to these two significant effects dropped in the Migdal-Eliashberg formalism, the anisotropic $s_{++}$-wave state in heavily electron-doped FeSe is satisfactorily explained. The proposed "inter-electron-pocket pairing mechanism" will enlarge Tc in other Fe-based superconductors.

description: Stability and causality are studied for linear perturbations about equilibrium in Carter's multifluid theory. Our stability analysis is grounded on the requirement that the entropy of the multifluid, plus that of the environment, must be maximised at equilibrium. This allows us to compute a quadratic Lyapunov functional, whose positive definiteness implies stability. Furthermore, we verify explicitly that, also for multifluids, thermodynamic stability implies linear causality. As a notable stability condition, we find that the entrainment matrix must always be positive definite, confirming a widespread intuition.

Living and dying at home in rural Australia: District nursing advocacy
Creators: name: Reed, Frances Margaret
Publisher: name: La Trobe
Year: 2023

description: Health policies promoting choices for people living and dying in rural Australia are challenged by limited resources and access. District nurse advocacy may promote the individual values, choices and goals of people at home. The lack of evidence to guide district nursing end-of-life advocacy was confirmed by reviewing the existing literature. A pragmatic sequential mixed methods exploratory study was designed to answer the question of how district nurses advocate successfully for the end-of-life goals of rural Australians, with the objective of developing a practice model. In Phase 1 of the study, the reflection-action process of nurse agency theory informed the collection of written and in-depth interview narratives from seven rural Victorian district nurses. Interpretive descriptive analysis of the data produced findings that were tested in the Phase 2 survey of rural district nurses (n=91) from across Australia. The survey questionnaire included psychometric scales and open-ended questions. Data analysis with descriptive statistics and interpretative description confirmed and complemented the findings. The final data integration provided conceptual inferences suitable to compare with the existing literature and inform the development of a practice model of successful rural district nurse end-of-life advocacy. The model presents advocacy based on respect for people and their rights and values. The vulnerability experienced in the end-of-life arouses emotional responses that motivate respectful district nurses to advocate for the self-determination of goals. Willing investment in person-centred relationships, specialised rural knowledge, and feeling supported enable the development of emotional intelligence to inform the reflection/action of moral agency for district nurse advocacy success. Advocacy action increases access to choice through the use of holistic assessment, communication, and organisation to empower and support people successfully in self-determined goals. The model expands understanding of advocacy as a nursing-care philosophy that builds capacity for care choice and increases satisfaction with the rural end-of-life experience.

Single-sex schooling, gender and educational performance: Evidence using PISA data

Publisher: name: University of Limerick
Year: 2023
Subjects: Economics

description: The advantages and disadvantages of single-sex schooling continue to be a source of policy and public debate. Previous empirical evidence is somewhat ambiguous, with some studies finding a positive impact of single-sex schooling on education achievement and others finding no differences across school types. The relationship between single-sex schooling on academic outcomes is typically problematic to examine, as in most countries single-sex schools are selective and the numbers attending them are relatively small. In Ireland, a high proportion of secondary school children (~1/3) attend a single-sex school. In addition, these schools are largely state-funded and non-selective but differing in composition compared to mixed-sex schools. For this reason, the Irish educational system provides an interesting setting for exploring the outcomes of single-sex schooling. In this context, this study utilises the 2018 PISA data for Ireland to examine the relationship between single-sex education and mathematics, reading and science literacy performance for boys and girls, respectively, as well as differences across gender in these outcomes. We find significant raw gaps in reading, science and mathematics scores between females in single-sex and mixed-sex schools and in mathematics scores for males across the same school types. However, after controlling for a rich set of individual, parental and school-level factors we find that, on average, there is no significant difference in performance for girls or boys who attend single-sex schools compared to their mixed-school peers in science,
Bridging the Gap: Incorporating a Semantic Similarity Measure for Effectively Mapping PubMed Queries to Documents

description: The main approach of traditional information retrieval (IR) is to examine how many words from a query appear in a document. A drawback of this approach, however, is that it may fail to detect relevant documents where no or only few words from a query are found. The semantic analysis methods such as LSA (latent semantic analysis) and LDA (latent Dirichlet allocation) have been proposed to address the issue, but their performance is not superior compared to common IR approaches. Here we present a query-document similarity measure motivated by the Word Mover's Distance. Unlike other similarity measures, the proposed method relies on neural word embeddings to compute the distance between words. This process helps identify related words when no direct matches are found between a query and a document. Our method is efficient and straightforward to implement. The experimental results on TREC Genomics data show that our approach outperforms the BM25 ranking function by an average of 12% in mean average precision. Furthermore, for a real-world dataset collected from the PubMed search logs, we combine the semantic measure with BM25 using a learning to rank method, which leads to improved ranking scores by up to 25%. This experiment demonstrates that the proposed approach and BM25 nicely complement each other and together produce superior performance.

Human Resource Professionals' Role in Maintaining Employee Engagement during Merger; a case of Commercial Bank of Ethiopia and former Construction and Business Bank
Creators: name: Gebreselassie, Daniel
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The purpose of this study was to examine the level of HR role and employee engagement and then examining the relationship between the two variables. The study was made based on the interview conducted with some selected employees of the bank and the questionnaires administered to 315 clerical, professional and administrative employees of CBE and former CBB. Descriptive statistics and spearman correlation were used for the data analysis. Change requires active employee engagement that derived by active involvement of HR professionals. Due to a competitive scenarios, the bank need to have HR professionals who know their role and actively involved during such change through which the employees reach to the highest engagement level. The result of the this study revealed that the employee engagement and HR professionals involvement at CBE are low. From the study it was also noted that there exists a statistically significant positive relationship between employee engagement and the role of HR professionals. Hence, to achieve its vision of becoming a world class bank, CBE has to have employees who are highly engaged and actively involved HR professionals that strive to take their bank to the highest level

description: The mass of a Kerr black hole can be separated into irreducible and rotational components -the former is a lower limit to the energy that cannot be possibly extracted from the event horizon and is related to its area. Here we compute the irreducible masses of the stellar-mass black holes observed by gravitational-wave interferometers LIGO and Virgo. Using single-event data, we present a re-parametrization of the posterior distribution that explicitly highlights the irreducible and rotational contributions to the total energy. We exploit the area law to rank the black-hole mergers observed to date according to their irreversibility, thus providing a guide to selecting events for targeted tests of General Relativity. Using population fits, we compute the rate by which the total area of black-hole horizons increases due to the observable mergers.

description: Industrial upscaling frequently results in a different coating microstructure than the laboratory prototypes presented in the literature. Here, we investigate the wear behavior of physical vapor deposited (PVD) MoS2 coatings: A dense, nanocrystalline MoS2 coating, and a porous, prismatic-textured MoS2 coating. Transmission electron microscopy (TEM) investigations before and after wear testing evidence a crystallographic reorientation towards a basal texture in both samples. A basal texture is usually desirable due to its low-friction properties. This favorable reorientation is associated to a tribological compaction of the porous specimens. Following running-in, sliding under high contact pressure ultimately leads to a wear rate as small as for an ideal grown bulk MoS2 single crystal grown by chemical vapor deposition (CVD). This suggests that the imperfections of industrial grade MoS2 coatings can be remediated by a suitable pretreatment.
A Dynamic Subgrid Scale Model for Large Eddy Simulations Based on the Mori-Zwanzig Formalism

description: The development of reduced models for complex multiscale problems remains one of the principal challenges in computational physics. The optimal prediction framework of Chorin et al., which is a reformulation of the Mori-Zwanzig (M-Z) formalism of non-equilibrium statistical mechanics, provides a methodology for the development of mathematically-derived reduced models of dynamical systems. Several promising models have emerged from the optimal prediction community and have found application in molecular dynamics and turbulent flows. In this work, a new M-Z-based closure model that addresses some of the deficiencies of existing methods is developed. The model is constructed by exploiting similarities between two levels of coarse-graining via the Germano identity of fluid mechanics and by assuming that memory effects have a finite temporal support. The appeal of the proposed model, which will be referred to as the `dynamic-MZ-$τ$' model, is that it is parameter-free and has a structural form imposed by the mathematics of the coarse-graining process (rather than the phenomenological assumptions made by the modeler, such as in classical subgrid scale models). To promote the applicability of M-Z models in general, two procedures are presented to compute the resulting model form, helping to bypass the tedious error-prone algebra that has proven to be a hindrance to the construction of M-Z-based models for complex dynamical systems. While the new formulation is applicable to the solution of general partial differential equations, demonstrations are presented in the context of Large Eddy Simulation closures for Burgers equation, decaying homogeneous turbulence, and turbulent channel flow. The performance of the model and validity of the underlying assumptions are investigated in detail.

Year: 2017

description: x ABSTRACT Human resource management is critical for the successful operation and profitability of an organization since people are the main assets that operate in organizations. Reward practice is one of core activities underlying in human resource management. This study examined effect of reward and its effect on the employees' job satisfaction taking Lion International Bank S.C. as a case study. The study used both primary and secondary source of data. A quantitative research approach of the data collection used and 244 questionnaires were distributed and 235 completed usable questionnaires for response rate of 96% returned. Stratified random sampling method was used and employees were selected from each stratum with a simple random sampling technique. Data was analyzed using descriptive, correlation and multiple regression analysis. The study result has implied that promotion, sense of achievement, recognition and work freedom are found to have strong positive relationship with employees job satisfaction, moderate relationship obtained with pay and benefit and working condition .Whereas , insignificant relationship is obtained with bonus. The result that obtained from regression analysis implied variations in employees' job satisfaction were explained by reward variables. In order to boost the level of satisfaction of the employee, the researcher recommended that the concerned parties have to revise and improve the existing reward practices. Since the current study was completed using employees' perception data on employee job satisfaction the study, findings may not be fully representing the population. Therefore, future researchers shall use objective data on employee job satisfaction and make a more concrete finding that can be representing all Lion International Bank's employees.
Search for Higgs boson pair production in the four b quark final state in proton-proton collisions at $\sqrt{s} =$ 13 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2022
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search for pairs of Higgs bosons produced via gluon and vector boson fusion is presented, focusing on the four b quark final state. The data sample consists of proton-proton collisions at a center-of-mass energy of 13 TeV, collected with the CMS detector at the LHC, and corresponds to an integrated luminosity of 138 fb$^{-1}$. No deviation from the background-only hypothesis is observed. A 95% confidence level upper limit on the Higgs boson pair production cross section is observed at 3.9 times the standard model prediction for an expected value of 7.8. Constraints are also set on the modifiers of the Higgs field self-coupling, $κ_λ$, and of the coupling of two Higgs bosons to two vector bosons, $κ_\mathrm{2V}$. The observed (expected) allowed intervals at the 95% confidence level are $-$2.3 $\lt$ $κ_λ$ $\lt$ 9.4 ($-$5.0 $\lt$ $κ_λ$ $\lt$ 12.0) and $-$0.1 $\lt$ $κ_\mathrm{2V}$ $\lt$ 2.2 ($-$0.4 $\lt$ $κ_\mathrm{2V}$ $\lt$ 2.5). These are the most stringent observed constraints to date on the HH production cross section and on the $κ_\mathrm{2V}$ coupling.

description: We study present-day galaxy clustering in the EAGLE cosmological hydrodynamical simulation. EAGLE's galaxy formation parameters were calibrated to reproduce the redshift $z=0.1$ galaxy stellar mass function, and the simulation also reproduces galaxy colours well. The simulation volume is too small to correctly sample large-scale fluctuations and we therefore concentrate on scales smaller than a few mega parsecs. We find very good agreement with observed clustering measurements from the Galaxy And Mass Assembly (GAMA) survey, when galaxies are binned by stellar mass, color, or luminosity. However, low-mass red-galaxies are clustered too strongly, which is at least partly due to limited numerical resolution. Apart from this limitation, we conclude that EAGLE galaxies inhabit similar dark matter haloes as observed GAMA galaxies, and that the radial distribution of satellite galaxies as function of stellar mass and colour is similar to that observed as well.
