description: Gravity waves (GWs) transport energy within the atmosphere both in vertical and horizontal direction. While the former is considered in climate models via parameterizations, the latter is often not modeled in most long time simulations. Especially orographic GWs can propagate horizontally more than 1000 km from their sources, however, and thereby de- or accelerate winds in completely different regions. To remedy this, we present a model that is capable of describing orographic GW sources and the associated GWs and their propagation in the atmosphere. From this, we can approximate general propagation pattern, which in the following can be used in climate models (here EMAC) to improve the orographic GW parameterization. The first simulations show strong redistribution of wave drag from land masses and thereby a closing of the gap of missing wave drag at 60°S.

Assessment of Integrated Housing Development Program in Addis Ababa: Housing Provision and Employment Creation
Creators: name: Hussen, Jemila
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2010

description: The major goals of the Integrated Housing Development Program in Addis Ababa (IHDPAA) are government housing production to meet the housing needs of the low and medium income people and also to create mass employment opportunity for Micro and Small Enterprises (MSEs). The purpose of this paper is to assess the effectiveness of the Program in meeting these two goals and the challenges that are facing the Program in meeting these goals. Questionnaires had been distributed for condominium house owners on a random basis and to MSE operators by using stratified sampling method in Arada, Bole and Nifas Silk Lafto Sub Cities. Focus Group Discussion was conducted with Site committee members and MSE supervisors in the above selected sub cities in addition to the in - depth interview with MSE and housing officials from Addis Ababa Housing Development Project Office, Ministry of Works and Urban Development, and the selected sub Cities. Percentages, tables, graphs and coefficient of correlation by using SPSS version 17.0 were used in analyzing and examining the quantitative data. The empirical results indicate that IHDPAA is not achieving its goal as originally planned. The first goal of meeting the housing demand of low and medium income people did not achieve due to slow rate of housing production, low income level of residents, absence of housing finance, lack of serviced land and lack of institutional capacity to effectively implement the Program. The Program is successful in meeting the second goal that is creating employment opportunity. The limitation of the Program with regard to employment is that the jobs created lacks sustainability. The findings indicate that MSEs that are participating in the Program face different challenges of growth and expansion. Therefore, the study suggests that the Program should consider alternative housing delivery mechanisms to meet the housing demand of the city especially the housing needs of the low and medium income people who are more vulnerable to the problem. Supporting the MSEs, by solving the challenge they face, can enhance the job opportunity that can be created by the Program. In addition, the government should consider other policy interventions that encourage labor intensive technologies in order to reduce the unemployment problem. Therefore, this study can be used as an important reference on some issues related to IHDPAA in order to improve the effectiveness of the Program

description: Call-Center stellen mittlerweile eine gängige Form der Organisation des Kundenkontakts von Unternehmen dar. Von den in Call-Center tätigen Agents werden dabei besondere kommunikative und soziale Fertigkeiten erwartet. Zusammen mit der in Call-Centern oft beobachtbaren jungen Altersstruktur ergibt sich eine spezifische Kommunikationskultur. Am Beispiel eines Call-Centers einer Direktbank wird sichtbar, wie diese Kultur der Kommunikation zum Teil subtil, zum Teil jedoch auch ganz explizit ausländische Kunden exkludiert. Dabei wirken nicht nur Sprachprobleme, sondern auch Stereotypen und Vorurteile. Besonders prägnant scheinen diese Vorurteile in dem von uns untersuchten Call-Center auch gegenüber Personen aus den Neuen Bundesländern zu bestehen: Der "Ossi" sei nicht direktbankfähig, lautet die lapidare Einschätzung, die auch vom Unternehmen zumindest tendenziell mitgetragen zu werden scheint. Die Entwicklung interkultureller Kompetenz für die Gesprächssituation und eine Aufarbeitung bestehender Vorurteile können aus der Sicht von Unternehmen Versuche darstellen, ausländische bzw. als nicht direktbankfähig eingeschätzte Kundengruppen auch in die Call-Center Arbeit mit einzubeziehen und so Vorteile für beide Seiten zu schaffen.

description: Hydrogen deuteride (HD) is prevalent in a wide variety of astrophysical environments, and measuring its large-scale distribution at different epochs can in principle provide information about the properties of these environments. In this paper, we explore the prospects for accessing this distribution using line intensity mapping of emission from the lowest rotational transition in HD, focusing on observations of the epoch of reionization ($z\sim6-10$) and earlier. We find the signal from the epoch of reionization to be strongest most promising, through cross-correlations within existing [CII] intensity mapping surveys. While the signal we predict is out of reach for current-generation projects, planned future improvements should be able to detect reionization-era HD without any additional observations, and would help to constrain the properties of the star-forming galaxies thought to play a key role in reionization. We also investigate several avenues for measuring HD during "cosmic dawn" ($z\sim10-30$), a period in which HD could provide one of the only complementary observables to 21$\,$cm intensity maps. We conclude that existing and planned facilities are poorly matched to the specifications desirable for a significant detection, though such a measurement may be achievable with sustained future effort. Finally, we explain why HD intensity mapping of the intergalactic medium during the cosmic dark ages ($z\gtrsim 30$) appears to be out of reach of any conceivable experiment.

The Importance of Integrating Quality Practices in to Strategic Management: Case Study on Ayka Addis Textile and Investment Group
Creators: name: Kepa, Baldada
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: It is obvious that quality tools are needed because intense global competition, changing customer needs and the changing business environment has forced many organizations to examine their organizational goals and to re-evaluate how to meet these challenges. This extreme global competition has forced many organizations to develop action plans to respond to an increasingly competitive market. One such action plan identified was the integration of quality practices and principles with strategic planning of the industry. The research investigates the importance and usefulness of integrating quality practices in the strategic management process of organizations. The main objective of the research is to explore and present the integration of quality practices into the strategic management process of organizations in the Ayka Addis Textile and Investment Group. Selected quality practices such as TQM, SQM, ISO 9001:2000, Hoshin Kanri and Six -Sigma are identified. These practices are integrating with the strategic management processes of the organizations and empirically tested. The empirical data were obtained from a combination of qualitative and quantitative research methods and the model which is regression analysis and correlation to test the validity, significance and the relationship between the selected variables. The conceptual framework used the variables on quality practices and their integration with strategic planning. The result of this study indicates that there is an integration of quality practices in to strategic management process. Key words: quality practices, strategic management, Ayka Addis Textile and Investment group

description: We measure spectrally and spatially resolved high-order harmonics generated in argon using chirped multi-cycle laser pulses. Using a stable, high-repetition rate laser we observe detailed interference structures in the far-field. The structures are of two kinds; off-axis interference from the long trajectory only and on-axis interference including the short and long trajectories. The former is readily visible in the far-field spectrum, modulating both the spectral and spatial profile. To access the latter, we vary the chirp of the fundamental, imparting different phases on the different trajectories, thereby changing their relative phase. Using this method together with an analytical model, we are able to explain the on-axis behaviour and access the dipole phase parameters for the short (\(α_s\)) and long (\(α_l\)) trajectories. The extracted results compare very well with phase parameters calculated by solving the time-dependent Schrödinger equation. Going beyond the analytical model, we are also able to successfully reproduce the off-axis interference structure.
title: Regulation of type I interferon response of macrophages to virus infections
Creators: name: Wang, Yan
Publisher: name: University of Liverpool Repository
Year: 2029

description: Macrophage, a versatile sentinel immune cell in host defence, not only is the major type I interferons (IFNs-I) producer upon virus infections, but also acts as an important target cell for many RNA viruses. However, the regulatory mechanism for the IFNs-I response of macrophages to respond to a viral challenge is not fully understood. Adhesion and degranulation-protein adaptor protein (ADAP), originally identified in T-cells as a key regulatory adaptor protein in TCR signalling and T-cell adhesion, has emerged as a critical regulator of innate immune cells including macrophages, mast cells and dendritic cells. Despite this, the link of ADAP to the polarization and IFNs-I responses of macrophages to RNA virus infection remains elusive.
 
In this project, I show that ADAP, an immune adaptor protein, is indispensable for the induction and sustaining of IFNs-I signalling in macrophages response to virus infection via inhibition of the conjugation of ubiquitin-like interferon-stimulated gene 15 (ISG15) to RIG-I. Firstly, ADAP deficiency exhibits increased susceptibility to RNA-virus infection in vivo accompanied by higher viral load in macrophages. Subsequently, ADAP selectively interacts with RIG-I but not MDA5, and the C-terminal domain (CTD) of RIG-I is responsible for ADAP binding. The interaction of ADAP with RIG-I occurs mainly on mitochondria but not lipid rafts in macrophages, which is induced by RNA virus infections or LPS stimulation. Moreover, I show ADAP deficiency leads to an enhancement of ISGylation of RIG-I, whereas overexpression of ADAP exhibits the opposite effect in vitro, indicating ADAP inhibits RIG-I ISGylation during viral infections. Finally, the RIG-I – MAVS association is slightly decreased in ADAP deficiency, which reduces the RNA virus-induced phosphorylation of IRF3 and TBK1, and the production of type I IFNs in macrophages. Taken together, my data demonstrates that ADAP exerts an antagonistic activity in the cell-intrinsic control of RIG-I ISGylation for RIG-I – IFNs-I signalling in response to RNA virus infections in macrophages.

description: Public transport ridership around the world has been hit hard by the COVID-19 pandemic. Travellers are likely to adapt their behaviour to avoid the risk of transmission and these changes may even be sustained after the pandemic. To evaluate travellers' behaviour in public transport networks during these times and assess how they will respond to future changes in the pandemic, we conduct a stated choice experiment with train travellers in the Netherlands. We specifically assess behaviour related to three criteria affecting the risk of COVID-19 transmission: (i) crowding, (ii) exposure duration, and (iii) prevalent infection rate. Observed choices are analysed using a latent class choice model which reveals two, nearly equally sized traveller segments: 'COVID Conscious' and 'Infection Indifferent'. The former has a significantly higher valuation of crowding, accepting, on average 8.75 minutes extra waiting time to reduce one person on-board. Moreover, they demonstrate a strong desire to sit without anybody in their neighbouring seat and are quite sensitive to changes in the prevalent infection rate. By contrast, Infection Indifferent travellers' value of crowding (1.04 waiting time minutes/person) is only slightly higher than pre-pandemic estimates and they are relatively unaffected by infection rates. We find that older and female travellers are more likely to be COVD Conscious while those reporting to use the trains more frequently during the pandemic tend to be Infection Indifferent. Further analysis also reveals differences between the two segments in attitudes towards the pandemic and self-reported rule-following behaviour. The behavioural insights from this study will not only contribute to better demand forecasting for service planning but will also inform public transport policy decisions aimed at curbing the shift to private modes.

description: In this paper, we propose a new framework for treating the angular information in the pulsar timing array response to a gravitational wave background based on standard cosmic microwave background techniques. We calculate the angular power spectrum of the all-sky gravitational redshift pattern induced at the earth for both a single bright source of gravitational radiation and a statistically isotropic, unpolarized Gaussian random gravitational wave background. The angular power spectrum is the harmonic transform of the Hellings & Downs curve. We use the power spectrum to examine the expected variance in the Hellings & Downs curve in both cases. Finally, we discuss the extent to which pulsar timing arrays are sensitive to the angular power spectrum and find that the power spectrum sensitivity is dominated by the quadrupole anisotropy of the gravitational redshift map.

Die sozialwissenschaftliche Arbeitswissenschaft kann hierzu aufgrund ihrer Analysefähigkeit einen wichtigen Beitrag leisten, in dem sie - ansetzend an den Widersprüchen der neuen Arbeitsformen - die Begrenzungen und Voraussetzungen analysiert, die es den arbeitenden Subjekten erst ermöglichen, die Chancen der neuen pluralen Arbeitswelt zu nutzen. Dazu muss sie jedoch ihre Forschungsschwerpunkte und -konzepte überdenken. So muss sie ihre noch immer deutlich wahrnehmbare Fokussierung auf die industrielle Arbeit und den damit verbundenen Hintergrundannahmen lösen und ihren theoretischen Bezugsrahmen weiterentwickeln. Wachsende Bedeutung erlangen insbesondere neue Formen sozialwissenschaftlicher Wissensproduktion, die eine Neudefinition des Verhältnisses von Analyse und Gestaltung in der sozialwissenschaftlichen Arbeitswissenschaft ermöglichen und damit zur Erhöhung der Leistungsfähigkeit der Disziplin beitragen.

description: We present a weighted BFBT approximation (w-BFBT) to the inverse Schur complement of a Stokes system with highly heterogeneous viscosity. When used as part of a Schur complement-based Stokes preconditioner, we observe robust fast convergence for Stokes problems with smooth but highly varying (up to 10 orders of magnitude) viscosities, optimal algorithmic scalability with respect to mesh refinement, and only a mild dependence on the polynomial order of high-order finite element discretizations ($Q_k \times P_{k-1}^{disc}$, order $k \ge 2$). For certain difficult problems, we demonstrate numerically that w-BFBT significantly improves Stokes solver convergence over the widely used inverse viscosity-weighted pressure mass matrix approximation of the Schur complement. In addition, we derive theoretical eigenvalue bounds to prove spectral equivalence of w-BFBT. Using detailed numerical experiments, we discuss modifications to w-BFBT at Dirichlet boundaries that decrease the number of iterations. The overall algorithmic performance of the Stokes solver is governed by the efficacy of w-BFBT as a Schur complement approximation and, in addition, by our parallel hybrid spectral-geometric-algebraic multigrid (HMG) method, which we use to approximate the inverses of the viscous block and variable-coefficient pressure Poisson operators within w-BFBT. Building on the scalability of HMG, our Stokes solver achieves a parallel efficiency of 90% while weak scaling over a more than 600-fold increase from 48 to all 30,000 cores of TACC's Lonestar 5 supercomputer.

description: We study Tan's contact, i.e. the coefficient of the high-momentum tails of the momentum distribution at leading order, for an interacting one-dimensional Bose gas subjected to a harmonic confinement. Using a strong-coupling systematic expansion of the ground-state energy of the homogeneous system stemming from the Bethe-Ansatz solution, together with the local-density approximation, we obtain the strong-coupling expansion for Tan's contact of the harmonically trapped gas. Also, we use a very accurate conjecture for the ground-state energy of the homogeneous system to obtain an approximate expression for Tan's contact for arbitrary interaction strength, thus estimating the accuracy of the strong-coupling expansion. Our results are relevant for ongoing experiments with ultracold atomic gases.

The Role of Selected Promotional Elements in Building Brand Equity: The Case of Commercial Bank of Ethiopia
Creators: name: Alemu, Tsegaye
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: This study was carried out with the intention of examining the role of selected promotional elements in building brand equity by taking the case of Commercial Bank of Ethiopia (CBE). The research tried to look at the effect of television and radio advertising, non-price sales promotion and sponsorship programs that are used by the bank in positively contributing to the development of brand equity through the mediating dimensions of brand equity. These dimensions namely, brand awareness, brand association, perceived quality and brand loyalty are conceptualized as mediation routes between promotional elements and brand equity. Primary data was collected from customers of CBE from branches in Addis Ababa using structured questionnaire by applying non-probability sampling techniques. The study applied Structural Equation Modeling to test hypotheses and determine the effect relationships between variables. The study found out that, television advertising, non-price sales promotion and sponsorship programs of CBE positively affect brand equity through the four brand equity dimensions. On other hand, radio advertising was found to have no effect on the dimensions and the resulting brand equity.

description: Contexte. Environ 5% des infections associées aux soins sont dues à des micro-organismes de l’environnement. Nous avons récemment investigué deux épidémies (une liée à Citrobacter freundii producteur d’OXA-48 et l’autre à Legionella pneumophila) dont l’origine probable était les toilettes ; une autre étude a montré que les salles de bains de patients ayant une diarrhée à Clostridioides difficile étaient fortement contaminées par des spores. Objectif. L’objectif de cette étude expérimentale était d’évaluer le rôle potentiel des toilettes dans la dissémination environnementale de ces bactéries. Matériel et méthode. Une suspension calibrée de chacune des bactéries (C. freundii, C. difficile, L. pneumophila) a été versée dans le siphon des toilettes. Après tirage de la chasse d’eau, la contamination environnementale a été évaluée en disposant 15 boîtes de Pétri à des distances variables autour des sanitaires et en prélevant l’air par impaction à l’aide d’un biocollecteur. Les boîtes de Pétri ont été incubées à 37°C pendant une durée et sous une atmosphère adaptées à chaque bactérie. Résultats. Au total, 25/170 (14,7%) prélèvements étaient positifs à C. freundii (24 « surfaces » et 1 « air »), 62/187 (33,2%) à C. difficile (40 surfaces et 22 airs) et 72/221 (32,6%) à L. pneumophila (59 surfaces et 13 airs). La fréquence de contamination augmentait avec le niveau de la contamination de l’eau des siphons et diminuait avec la distance par rapport aux sanitaires. Discussion-Conclusion. Ces résultats expérimentaux montrent que l’utilisation des toilettes génère une importante quantité d’aérosols contaminés et entraîne une contamination environnementale. Cette étude souligne la nécessité d’utiliser l’abattant des toilettes avant de tirer la chasse d’eau.

The nonintegrability of this system and idea of the proof are communicated. Moreover, the analysis of global dynamics by means of Poincaré cross sections is given and local analysis in the neighborhood of an equilibrium is performed by applying the Birkhoff normal form. Conditions of linear stability are determined and some particular periodic solutions are identified.

description: We consider electrovacuum black hole spacetimes in classical extensions of Eddington-inspired Born-Infeld gravity. By rewriting Born-Infeld action as the square root of the determinant of a matrix $\hatΩ$, we consider the family of models $f (|\hatΩ|)$, and study black hole solutions for a power-law family of models labelled by a simple parameter. We show how the innermost structure of the corresponding black holes is modified as compared to their General Relativity counterparts, discussing in which cases a wormhole structure replaces the point-like singularity. We go forward to argue that in such cases a geodesically complete and thus non-singular spacetime is present, despite the existence of curvature divergences at the wormhole throat.

description: Using the non-semisimple Temperley-Lieb calculus, we study the additive and monoidal structure of the category of tilting modules for $\mathrm{SL}_{2}$ in the mixed case. This simultaneously generalizes the semisimple situation, the case of the complex quantum group at a root of unity, and the algebraic group case in positive characteristic. We describe character formulas and give a presentation of the category of tilting modules as an additive category via a quiver with relations. Turning to the monoidal structure, we describe fusion rules and obtain an explicit recursive description of the appropriate analog of Jones-Wenzl projectors. We also discuss certain theta values, the tensor ideals, mixed Verlinde quotients and the non-degeneracy of the braiding.

Assessment of Revenue Generation and its Challenges: A Study in Haddiya Zone, SNNPRS, Ethiopia
Creators: name: Abrham, Dea
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: The adverse situation in the various local government areas of SNNPR'S, Ethiopia has led the researcher to go into this very topic. Hence, the purpose of this work is to enlighten people, mostly students in the school of financial studies on how revenue generated in local governments, problems confronting them as regards revenue generation as well as prospects. The function of revenue generation is basic sources of economic engagement for the local government to offer economic, social and services provision for citizen. On the other hands, revenue generation in its unique behavior, independently clarify mandatory act to this organ to fulfil those provision for citizen and development desire of the populace. The aim of the study is to assess revenue generation and its challenges in local level, in Haddiya Zone, by employing qualitative and quantitative research methods. The study adopts the participant observation method and source data from the secondary sources. Sample of 200 were included in the study by employing purposive sampling technique and 176 questionnaires returned back then analyzed. The observation, focus group discussion and statistical analysis employed for study. Additionally, secondary data gathered from revenue authority and finance department with four-year internal collected revenue and regional transfer report, years from 2015/16 to 2018/19. The paper holds that the revenue collection without revenue independence, collection performance practice without best mechanism and absence of resource mobilization in studied way, lack of practice supporting revenue generation management, shortage of revenue collecting electronics infrastructure wide area network system, that have directly affect revenue generation. Based on this, the paper recommended among other that, local government, Haddiya Zone Tax Authority and respective body should commit to secure sustainable internal revenue generation, improve positively affecting factors, forward feedback to the area of complex tax laws to the concerned authority, and encourage taxpayers who good perform.

description: A combined Doppler backscattering/cross-polarization scattering (DBS/CPS) system is being deployed on MAST-U, for simultaneous measurements of local density turbulence, turbulence flows, and magnetic turbulence. In this design, CPS shares the probing beam with the DBS and uses a separate parallel-viewing receiver system. In this study, we utilize a modified GENRAY 3D ray-tracing code, to simulate the propagation of the probing and scattered beams. The contributions of different scattering locations along the entire beam trajectories are considered, and the corresponding local $\tilde{\mathbf{B}}$ wavenumbers are estimated using the wave-vector matching criterion. The wavenumber ranges of the local $\tilde{\mathbf{B}}$ that is detectable to the CPS system are explored for simulated L- and H-mode plasmas.
Teacher Agency For Change And Development In Higher Education: A Scoping Literature Review
Creators: name: Cong-Lem, Ngo
Publisher: name: Monash University
Year: 2024

description: This paper reviews 42 empirical studies on tertiary educators' professional agency, identifying five key practices: pedagogical innovation, research engagement, professional learning, curriculum change, and maintaining well-being. Teacher agency has been variably conceptualized as being influenced by internal and external factors, such as curriculum reforms, social relationships, personal identities, beliefs, and emotions. Individual capacities and enactment strategies, along with contextual conditions like leadership and support, are crucial for effective teacher agency. Implications for policy-making and teacher professional development to foster effective change are discussed, with a conceptual framework proposed for investigating teacher agency holistically in its complexity.

Waves propagating parallel to the magnetic field in relativistically hot plasmas: A hydrodynamic model
Creators: name: Andreev, Pavel A.
Publisher: name: arXiv
Year: 2021
Subjects: subject: Plasma Physics (physics.plasm-ph)

description: The high-frequency part of spectrum of electromagnetic waves propagating parallel to the external magnetic field is considered for the macroscopically motionless plasmas with the relativistic temperatures $T\sim m_{e}c^{2}$, where $m_{e}$ is the mass of electron, $c$ is the speed of light. The analysis is based on the novel hydrodynamic model based on four equations for the material fields which can be combined in two four vectors. These material fields are the concentration and the velocity field \emph{and} the average reverse relativistic $γ$ functor and the flux of the reverse relativistic $γ$ functor. In the nonrelativistic regime we have three waves (the ions are assumed to be motionless). Strong thermal effects lead to a coefficient in front of cyclotron frequency which decreases the effective contribution of the cyclotron frequency. At $T=0.1m_{e}c^{2}$ we have a decrease of area of existence of fast magneto-sound wave from the area of the large frequencies. While the area of existence of extraordinary waves becomes larger towards smaller frequencies. The strong magnetic field limit $\midΩ_{e}\mid > ω_{Le}$ additional wave appears with frequency below thermally decreased cyclotron frequency, where $\midΩ_{e}\mid$ is the electron cyclotron frequency, and $ω_{Le}$ is the Langmuir frequency. Further increase of temperature leads to the disappearance of fast magneto-sound wave and to the considerable increase of area of existence of extraordinary towards smaller frequencies.

description: Une enquête a été proposée aux infirmières pratiquant des soins au domicile des patients pour évaluer leurs besoins en termes de prévention des infections associées aux soins (IAS). Du 1er février au 30 juin 2021, 131 infirmières ont complété le questionnaire en ligne. Les dispositifs vasculaires et plus particulièrement les accès centraux étaient majoritairement perçus comme des dispositifs à haut ou très haut risque d’infection, ainsi que les soins à un porteur de bactérie multirésistante aux antibiotiques (BMR) ou hautement résistante aux antibiotiques émergente (BHRe). Les attentes exprimées étaient en faveur de fiches professionnelles techniques facilement consultables sur les outils de communication mobiles. Les documents d’information aux patients ou aidants concernant les BMR et BHRe, les stomies et les sondes urinaires étaient souhaités par la moitié des répondantes. Cette consultation permettra de hiérarchiser les actions à l’intention des infirmières, notamment sous la forme de fiches techniques en coordination avec les missions nationales (Surveillance et prévention de la résistance aux antibiotiques et des infections associées aux soins en soins de ville et secteur médico-social [Primo] et Mission d’appui transversal à la prévention des infections associées aux soins [Matis]).
