description: Introduction: A connection between executive function (EF) performance and prosody was previously found in numerous mental disorders (Filipe et al., 2018; Le et al., 2011; Nevler et al., 2017). However, it is so far unresolved how different subdomains of EF and prosody are related to each other. Thus, the present study strived to explore the relationships of EF and prosody using a machine learning (ML) regression approach aiming to predict EF performance from various prosodic features.Methods: Healthy participants (n = 231) performed several spontaneous speech tasks, as well as commonly used EF tests, spanning different EF subdomains. Prosodic features were extracted automatically from the speech samples. We then used a standard ML approach to predict EF performance from prosody. As is common, we controlled for confounding effects of age, sex, and education Subsequently, the most predictive features for each of the successfully predicted EF variables were identified.Results: Results indicated that spectral prosodic parameters were particularly important for successful prediction, which is in line with previous literature (Le et al., 2011). However, a thorough assessment of the analysis pipeline revealed a leakage of the effects of sex, age, and education into the prediction, basically indicating the prediction performance – at least for some of the variables – was mainly driven by sex, age, and education confounds, rather than our prosody features. While results of ML analyses might appear to fit with previous results, present findings strongly underline the importance of educated control of any ML pipeline. Thus, we suggest running sanity checks for predicting cognitive performance as well as caution with the interpretation of ML prediction results.Discussion:Taking these methodological considerations into account, the outcome of the present study provides insights into the specific relationships between prosody and executive function performance, concurrently warning about possible pitfalls with the use of ML. While our findings are in line with previous studies (Filipe et al., 2018; Le et al., 2011; Nevler et al., 2017), further research should investigate whether the predictive power of prosody can serve as a biomarker of executive dysfunction in the future.
Position-dependent radiative transfer as a tool for studying Anderson localization: Delay time, time-reversal and coherent backscattering

description: Previous work has established that the localized regime of wave transport in open media is characterized by a position-dependent diffusion coefficient. In this work we study how the concept of position-dependent diffusion affects the delay time, the transverse confinement, the coherent backscattering, and the time reversal of waves. Definitions of energy transport velocity of localized waves are proposed. We start with a phenomenological model of radiative transfer and then present a novel perturbational approach based on the self-consistent theory of localization. The latter allows us to obtain results relevant for realistic experiments in disordered quasi-1D wave guides and 3D slabs.

description: Statistical fraud detection consists in making a system that automatically selects a subset of all cases (insurance claims, financial transactions, etc.) that are the most interesting for further investigation. The reason why such a system is needed is that the total number of cases typically is much higher than one realistically could investigate manually and that fraud tends to be quite rare. Further, the investigator is typically limited to controlling a restricted number k of cases, due to limited resources. The most efficient manner of allocating these resources is then to try selecting the k cases with the highest probability of being fraudulent. The prediction model used for this purpose must normally be regularised to avoid overfitting and consequently bad prediction performance. A loss function, denoted the fraud loss, is proposed for selecting the model complexity via a tuning parameter. A simulation study is performed to find the optimal settings for validation. Further, the performance of the proposed procedure is compared to the most relevant competing procedure, based on the area under the receiver operating characteristic curve (AUC), in a set of simulations, as well as on a credit card default dataset. Choosing the complexity of the model by the fraud loss resulted in either comparable or better results in terms of the fraud loss than choosing it according to the AUC.

description: The aim of this study was to assess quality of service delivery and its impact on customer satisfaction. It described the relationship between service quality dimensions and customer satisfaction in selected commercial banks in Addis Ababa and identifies the most important dimension of service quality for commercial bank customers. Also, it shows the gaps between customer's expectation and perception on the quality of service delivery system in the banks. The research was carried out through the use of cross-sectional survey design and primarily based on data collected through structured questionnaire developed based on SERVQUAL instrument. Convenience sampling technique was used to select 200 respondents from four commercial banks. The data has been analyzed via reliability method, descriptive statistics, Spearman's correlation and gap analysis. The finding shows that all the five service quality dimensions are positively related with customer satisfaction. Reliability shows the highest positive relation with customer satisfaction and tangibles demonstrates the least positive relation with customer satisfaction. The result also indicates that the overall service quality perceived by consumers was not satisfactory meaning expectations exceeded perceptions and all the dimensions showed higher expectations than perceptions of services. This implies that the selected banks in Addis Ababa are not providing the level of service quality demanded by customers. The findings suggest that commercial banks need to improve all the dimensions of service quality. Keywords: Service quality, Customer satisfaction

description: Welchen Beitrag im Wissens- und Technologietransfer können Akteure und Einrichtungen aus dem Hochschulbereich verwirklichen, wenn sie mit industriellen Partnern zusammenarbeiten? Diese Frage steht im Zentrum der folgenden Ausführungen, die auf einer einjährigen empirischen Pilotstudie fußen. In der Studie werden qualitative Methoden genutzt, um den Transferbeitrag kombitechnologisch orientierter Forschungs- und Entwicklungseinrichtungen (F&E) aus dem Hochschulbereich auf einer organisationalen Ebene zu beleuchten. Die untersuchten Orte legen es nahe, einerseits mithilfe von Invention/Innovation und andererseits von Interaktion/Organisation voneinander unterschieden zu werden. Auf der Basis dieser Differenzpaare läßt sich anschließend eine (Ideal-)Typologie von vier Ortsprofilen entwickeln, die als Untersuchungs- und Erklärungskonzept dient. Das Typologiekonzept wird abschließend genutzt, um die Transferpotentiale und -leistungen der unterschiedlichen F&E-Orte trennscharf herauszuarbeiten.
description: What contribution can human and material resources in the universities make to the transfer of knowledge and technology in partnership with industry? This is the central question in the following discourse, which is based on a one-year empirical pilot study. In this investigation, qualitative methods are used to illuminate, on an organizational level, the transfer contribution of research and development facilities (R&D) in those universities which are oriented towards combined-technologies. The locales under examination lend themselves to a distinction being made on the one hand with the help of the differentiation "invention/innovation", and "interaction/organization" on the other hand. On the basis of this differential pairing it will be possible to develop an (ideal) typology of four locales, which can serve as objects of examination and explanation. Finally, the typological concept will be used to make a clear distinction between the transfer potential and achievement of the various R&D locales.

description: By the year 2050, over 60% of India's population would suffer from acute food insecurity due to the present agricultural growth rate. There is an immediate need for increased production, but farmers are becoming indebted due to high expenses and unstable market prices. A grassroots movement known as zero budget natural farming (ZBNF) seeks to increase agricultural profitability through cost-cutting measures. Various states in the Nation have adopted ZBNF and turned a portion of their fertile agricultural land to ZBNF. However, due to the little external nutrient inputs, there is a chance of decline in food production, which led to the sustainability of ZBNF into doubt.  Crops such as legumes are probably going to supply the majority of the nitrogen, even though, Only 52–80% of the average national nitrogen applied as fertilizer is predicted to be delivered, even with full potential nitrogen fixation and release. Therefore, yield penalties are expected in higher-input conventional agricultural systems. Since only nitrogen may be biologically fixed from the environment, ZBNF may restrict the availability of other nutrients. To make sure that India's ability to feed itself is not compromised by mass conversion to ZBNF, hence more study is required in higher-input conventional agricultural systems.

description: The Bondi solution, which describes the radial inflow of a gas onto a non-rotating black hole, provides a powerful test for numerical relativistic codes. However, the Bondi solution is usually derived in Schwarzschild coordinates, which are not well suited for dynamical spacetime evolutions. Instead, many current numerical relativistic codes adopt moving-puncture coordinates, which render black holes in trumpet geometries. Here we transform the Bondi solution into trumpet coordinates, which result in regular expressions for the fluid flow extending into the black-hole interior. We also evolve these solutions numerically and demonstrate their usefulness for testing and calibrating numerical codes.

description: Every organization in the market has its own advertising objective, increase market share and sales, and build solid customer relations. The objective of the study was to determine the influence of advertising on organizational performance of fast moving consumer goods in the brewery industry in the case of St. Gorge Brewery. The research design adopted was cross sectional descriptive design. The population of the study comprised of the staff of St. Gorge brewery from the departments of marketing, sales, and distributors. The study used primary data which was collected using self-administered questionnaires. The data collected was analyzed using statistical package for social sciences and presented in tables. The study found out that advertisement helps the companies create awareness among customers for their products and services but also serves as a useful vehicle in promoting brand image of products and services offered at the target market. The study established that advertising in the case of St. Gorge brewery enables it to create good image and promote the reiterate purchase of its products create large market segment which leads to the development of larger market share, maintain superior stand in the industry, establish good relationship with potential customers and reduce consumer dissonance. The study further established that advertising helps St. Gorge brewery creates awareness, appeal, creation of standards through competition, conviction; minimize hindrances between the organization and customers. Advertising influences the sales performance as it enables the company to enhance the purchase of organizational products by the consumer, increase volume of sales, increase the profits of the organization and enhance the organization relationship with its customers.

description: We study the quantum correlations between the two remote qubits (sender and receiver) connected by the transmission line (homogeneous spin-1/2 chain) depending on the parameters of the sender's and receiver's initial states (control parameters). We consider two different measures of quantum correlations: the entanglement (a traditional measure) and the informational correlation (based on the parameter exchange between the sender and receiver). We find the domain in the control parameter space yielding (i) zero entanglement between the sender and receiver during the whole evolution period and (ii) non-vanishing informational correlation between the sender and receiver, thus showing that the informational correlation is responsible for the remote state creation. Among the control parameters, there are the strong parameters (which strongly effect the values of studied measures) and the weak ones (whose effect is negligible), therewith the eigenvalues of the initial state are given a privileged role. We also show that the problem of small entanglement (concurrence) in quantum information processing is similar (in certain sense) to the problem of small determinants in linear algebra. A particular model of 40-node spin-1/2 communication line is presented.

description: The link between metabolic syndrome (MetS) and neurodegenerative as well cerebrovascular conditions holds substantial implications for brain health in at-risk populations. This study elucidates the complex relationship between MetS and brain health by conducting a comprehensive examination of cardiometabolic risk factors, cortical morphology, and cognitive function in 40,087 individuals. Multivariate, data-driven statistics identified a latent dimension linking more severe MetS to widespread brain morphological abnormalities, accounting for up to 71% of shared variance in the data. This dimension was replicable across sub-samples. In a mediation analysis we could demonstrate that MetS-related brain morphological abnormalities mediated the link between MetS severity and cognitive performance in multiple domains. Employing imaging transcriptomics and connectomics, our results also suggest that MetS-related morphological abnormalities are linked to the regional cellular composition and macroscopic brain network organization. By leveraging extensive, multi-domain data combined with a dimensional stratification approach, our analysis provides profound insights into the association of MetS and brain health. These findings can inform effective therapeutic and risk mitigation strategies aimed at maintaining brain integrity.

description: Der Beitrag präsentiert Erfahrungen, die im Rahmen betrieblicher Umgestaltungsprojekte mit dem Einsatz ausgewählter Teile des MTO-Instruments als arbeitswissenschaftlichem Analyseverfahren gemacht wurden. Neben der Darstellung der teilweise divergierenden Anforderungen an solche Instrumente im konkreten Projektzusammenhang und den bei der Anwendung auftretenden spezifischen Anpassungsproblemen wird auf die Frage eingegangen, welche Folgen der Einsatz solcher Hilfsmittel für die Beziehung zwischen Berater und beratenem Unternehmen hat. Neben der Feststellung, dass relevante und sensible Informationen und Interpretationen erst im Verlauf eines sich stabilisierenden Beratungsprozesses erzeugt werden, erwiesen sich die eingesetzten Module als praktikables, aber relativ 'anpassungsaufwendiges' Mittel, das durchaus zu einer fruchtbaren Kooperation im Beratungsprozess beitragen konnte. Die Aufgabe, arbeitswissenschaftliche Instrumente in dieser Hinsicht weiterzuentwickeln, bleibt dennoch bestehen.
description: The article is focusing on experiences in using selected modules of the MTO instrument - an industry science analysis tool - in organizational restructuring projects. First, the article is presenting different requests for selecting and using this kind of tool. It will then give a report on the need and extent to adjust the modules to the specific needs of the restructuring project. Finally, the consequences of using the tool will be reflected focusing on the relationship and interaction of consultant and company. Highlighting the experience that relevant and confident information and interpretation are generated based on an ongoing and stable interaction during the consulting process, it can be said that the modules proved to be useful but too costly to be adapted to the specific conditions on the one hand. On the other hand the modules could quite well support the development of a fruitful cooperation. But the basic task is still to be solved: to further develop these tools towards being useful for developing social and interaction aspects of the processes.

description: This study aims to assess the toxicity of lead Pb+2 and anthracene in zebrafish (Danio rerio) eleutheroembryos survival, development, behaviour and neurotoxicity. Fish-embryo toxicity (FET) tests were conducted according to the OECD guideline TG 236. The video tracking system Zebrabox® was used to evaluate the effects of these chemicals on 120 hours post fecundation (hpf) larvae behaviour. Data showed that both chemicals have a moderate toxic effect on fish embryo survival: Pb+2 96 h-LC50 value was 76.51 mg/L. Anthracene 96 h-LC50 value was 133.35 mg/L. Anthracene decreased total swimming distance (TSD) and total swimming time (TST) suggesting hypoactivity. Although less pronounced, Pb+2 also affected locomotion by increasing distance travelled in rapid movements after 120 hpf exposure, suggesting hyperactivity. Besides, AChE was not responsive and sensitive to Pb+2 or anthracene after 120 hpf exposure.

description: Group testing study designs have been used since the 1940s to reduce screening costs for uncommon diseases; for rare diseases, all cases are identifiable with substantially fewer tests than the population size. Substantial research has identified efficient designs under this paradigm. However, little work has focused on the important problem of disease screening among clustered data, such as geographic heterogeneity in HIV prevalence. We evaluated designs where we first estimate disease prevalence and then apply efficient group testing algorithms using these estimates. Specifically, we evaluate prevalence using individual testing on a fixed-size subset of each cluster and use these prevalence estimates to choose group sizes that minimize the corresponding estimated average number of tests per subject. We compare designs where we estimate cluster-specific prevalences as well as a common prevalence across clusters, use different group testing algorithms, construct groups from individuals within and in different clusters, and consider misclassification. For diseases with low prevalence, our results suggest that accounting for clustering is unnecessary. However, for diseases with higher prevalence and sizeable between-cluster heterogeneity, accounting for clustering in study design and implementation improves efficiency. We consider the practical aspects of our design recommendations with two examples with strong clustering effects: (1) Identification of HIV carriers in the US population and (2) Laboratory screening of anti-cancer compounds using cell lines.

description: We report low temperature muon spin relaxation (muSR) measurements of the high-transition-temperature (Tc) cuprate superconductors Bi{2+x}Sr{2-x}CaCu2O{8+δ} and YBa2Cu3O6.57, aimed at detecting the mysterious intra-unit cell (IUC) magnetic order that has been observed by spin polarized neutron scattering in the pseudogap phase of four different cuprate families. A lack of confirmation by local magnetic probe methods has raised the possibility that the magnetic order fluctuates slowly enough to appear static on the time scale of neutron scattering, but too fast to affect $μ$SR or nuclear magnetic resonance (NMR) signals. The IUC magnetic order has been linked to a theoretical model for the cuprates, which predicts a long-range ordered phase of electron-current loop order that terminates at a quantum crictical point (QCP). Our study suggests that lowering the temperature to T ~ 25 mK and moving far below the purported QCP does not cause enough of a slowing down of fluctuations for the IUC magnetic order to become detectable on the time scale of muSR. Our measurements place narrow limits on the fluctuation rate of this unidentified magnetic order.

description: Obwohl Teilzeitarbeit in der Debatte um die Reduzierung der Arbeitslosigkeit seit Jahren eine wichtige Rolle spielt, ist der Führungskräfte-Bereich davon weitgehend ausgespart geblieben. Dies wird insbesondere mit den klassischen Steuerungs- und Kontrollaufgaben der Führungskräfte und ihrer Vorbildfunktion begründet. In einer interviewgestützten Fallstudie aus einem Chemieunternehmen mit (wenigen) teilzeitarbeitenden Führungskräften werden die Umstände, Bedingungen und Erfahrungen aus Sicht des Betriebes und der Betroffenen untersucht. Es zeigt sich, daß trotz der bestehenden Ansätze die Rahmenbedingungen für Führungskräfte-Teilzeitarbeit nach wie vor sehr ungünstig sind. Die Betroffenen erkaufen sich die Teilzeitarbeit mit einem Karrierstopp, dem Erfordernis ständiger Erreichbarkeit und einer massiven Arbeitsverdichtung.
description: Although part-time work is one of the most promising instruments in the struggle against unemployment, this discussion does not affect the management ranks in organisations, mainly substantiated by their functions of leading and controlling the workforce. In a case study from an enterprise of chemical industries with a few part-time working managers the authors examine the circumstances, conditions and experiences from the perspective of the organization and the participants. The results show that the frame and setting of part-time work in management is still very unfavourable. The participants must accept a career stop and a massive intensifying of their "reduced" work.

description: Email platforms need to generate personalized rankings of emails that satisfy user preferences, which may vary over time. We approach this as a recommendation problem based on three criteria: closeness (how relevant the sender and topic are to the user), timeliness (how recent the email is), and conciseness (how brief the email is). We propose MOSR (Multi-Objective Stationary Recommender), a novel online algorithm that uses an adaptive control model to dynamically balance these criteria and adapt to preference changes. We evaluate MOSR on the Enron Email Dataset, a large collection of real emails, and compare it with other baselines. The results show that MOSR achieves better performance, especially under non-stationary preferences, where users value different criteria more or less over time. We also test MOSR's robustness on a smaller down-sampled dataset that exhibits high variance in email characteristics, and show that it maintains stable rankings across different samples. Our work offers novel insights into how to design email re-ranking systems that account for multiple objectives impacting user satisfaction.

Quadratic band touching points and flat bands in two-dimensional topological Floquet systems

description: In this work we theoretically study, using Floquet-Bloch theory, the influence of circularly and linearly polarized light on two-dimensional band structures with Dirac and quadratic band touching points, and flat bands, taking the nearest neighbor hopping model on the kagome lattice as an example. We find circularly polarized light can invert the ordering of this three band model, while leaving the flat-band dispersionless. We find a small gap is also opened at the quadratic band touching point by 2-photon and higher order processes. By contrast, linearly polarized light splits the quadratic band touching point (into two Dirac points) by an amount that depends only on the amplitude and polarization direction of the light, independent of the frequency, and generally renders dispersion to the flat band. The splitting is perpendicular to the direction of the polarization of the light. We derive an effective low-energy theory that captures these key results. Finally, we compute the frequency dependence of the optical conductivity for this 3-band model and analyze the various interband contributions of the Floquet modes. Our results suggest strategies for optically controlling band structure and interaction strength in real systems.

Creators: name: Kiflu, Meseret
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The purpose of this study was to investigate factors that influence customers adoption of e-banking in Addis Ababa. Data was collected using questionnaire distributed to a sample of 384 with response rate of 81% from customers of the two selected banks. The chosen banks were Commercial bank of Ethiopia and Dashen bank which have a better e-banking service. Quantitative research approach was used to answer research questions. The collected data was analyzed using SPSS version 20.0 for descriptive analysis and inferential analysis. The relationship and influence of the factors was analyzed using Pearson correlation and multiples regression. The findings of the study showed that perceived ease of use, ICT infrastructure, security perception and information about e-banking have significant positive effect on the adoption of electronic banking except perceived risk which has significant but negative effect. Strategies are also recommended to enhance the e-banking services including formulating security policies and guidelines, making websites more user-friendly, reducing users risk concerns and the role of government in terms of improving ICT infrastructure. Finally, in order to bring about sustainable adaptation of e- banking services by financial institutions which best serves the customer needs, more research works are suggested to be done to further analyze the contribution of e-banking services to the larger economic transactions.

description: Metabolic Syndrome (MetS) is a serious condition that can be an early warning sign of heart disease and Type 2 diabetes. MetS is characterized by having elevated levels of blood pressure, cholesterol, waist circumference, and fasting glucose. There are many articles in the literature exploring the relationship between physical activity and MetS, but most do not consider the measurement error in the physical activity measurements nor the correlations among the MetS risk factors. Furthermore, previous work has generally treated MetS as binary, rather than directly modeling the risk factors on their measured, continuous space. Using data from the National Health and Nutrition Examination Survey (NHANES), we explore the relationship between minutes of moderate to vigorous physical activity (MVPA) and MetS risk factors. We construct a measurement error model for the accelerometry data, and then model its relationship between MetS risk factors with nonlinear seemingly unrelated regressions, incorporating dependence among MetS risk factors. The novel features of this model give the medical research community a new way to understand relationships between MVPA and MetS. The results of this approach present the field with a different modeling perspective than previously taken and suggest future avenues of scientific discovery.
Theory of surface Andreev bound states and tunneling spectroscopy in three-dimensional chiral superconductors

description: We study the surface Andreev bound states (SABSs) and quasiparticle tunneling spectroscopy of three-dimensional (3D) chiral superconductor by changing the surface (interface) misorientation angle of chiral superconductors. We obtain analytical formula of the energy dispersion of SABS for general pair potential when an original 4$\times$4 BdG Hamiltonian can be reduced to be two 2$\times$2 blocks. The resulting SABS for 3D chiral superconductors with pair potential given by $k_z(k_x + ik_y)^ν$ $(ν = 1, 2)$ has a complicated energy dispersion due to the coexistence of both point and line nodes. We focus on the tunneling spectroscopy of this pairing in the presence of applied magnetic field which induces Doppler shift of quasiparticle spectra. By contrast to previous known Doppler effect in unconventional superconductors, zero bias conductance dip can change into zero bias conductance peak by external magnetic field. We also study SABSs and tunneling spectroscopy for possible pairing symmetries of UPt$_3$ . For this purpose, we extend a standard formula of tunneling conductance of unconventional superconductor junctions in order to treat spin-triplet non-unitary pairings. The magneto tunneling spectroscopy, i.e., tunneling spectroscopy in the presence of magnetic field, can serve as a guide to determine the pairing symmetry of this material.

Improved Ab Initio Molecular Dynamics by Minimal Biasing with Experimental Data

description: Accounting for electrons and nuclei simultaneously is a powerful capability of ab initio molecular dynamics (AIMD). However, AIMD is often unable to accurately reproduce properties of systems such as water due to inaccuracies in the underlying electronic density functionals. This shortcoming is often addressed by added empirical corrections and/or increasing the simulation temperature. We present here a maximum-entropy approach to directly incorporate limited experimental data via a minimal bias. Biased AIMD simulations of water and an excess proton in water are shown to give significantly improved properties both for observables which were biased to match experimental data and for unbiased observables. This approach also yields new physical insight into inaccuracies in the underlying density functional theory as utilized in the unbiased AIMD.

From discrete to continuous percolation in dimensions 3 to 7

description: We propose a method of studying the continuous percolation of aligned objects as a limit of a corresponding discrete model. We show that the convergence of a discrete model to its continuous limit is controlled by a power-law dependency with a universal exponent $θ= 3/2$. This allows us to estimate the continuous percolation thresholds in a model of aligned hypercubes in dimensions $d = 3,\ldots,7$ with accuracy far better than that attained using any other method before. We also report improved values of the correlation length critical exponent $ν$ in dimensions $d = 4,5$ and the values of several universal wrapping probabilities for $d=4,\ldots,7$.

description: This paper develops an analytical framework for comparing religious ethics (Christianity, Judaism, Hinduism, Buddhism, Islam) and secular ethics (duties to nature and future generations, rights of future generations). The paper presents empirical results for OECD and non-OECD countries based on numerical simulations for current and maximum feasible parameter values and on panel data statistical analyses for marginal reliable changes of parameters. Secular ethics are beneficial, but unfeasible and unreliable in OECD countries; they are detrimental, unfeasible, and unreliable in non-OECD countries. Religious ethics were all beneficial and feasible in all countries; apart from Judaism, all religions were reliable in OECD countries. Apart from Buddhism, all religions were reliable in non-OECD countries.
