description: Recent observations by IceCube, notably two PeV cascades accompanied by events at energies ~ (30-400) TeV, are clearly in excess over atmospheric background fluxes and beg for an astroparticle physics explanation. Although some models of astrophysical accelerators can account for the observations within current statistics, intriguing features in the energy and possibly angular distributions of the events make worth exploring alternatives. Here, we entertain the possibility of interpreting the data with a few PeV mass scale decaying Dark Matter, with lifetime of the order of 10^27 s. We discuss generic signatures of this scenario, including its unique energy spectrum distortion with respect to the benchmark $E_ν^{-2}$ expectation for astrophysical sources, as well as peculiar anisotropies. A direct comparison with the data show a good match with the above-mentioned features. We further discuss possible future checks of this scenario.

Logophoricity in Ibibio
Creators: name: Newkirk, Lydia
Publisher: name: Zenodo
Year: 2019

description: This paper presents a description and analysis of logophoric pronouns in Ibibio.
 I show that Ibibio logophors, although they behave in most respects like typical
 logophoric pronouns in West African languages, obey Shift Together like shifted
 indexicals. In order to explain this data I propose that Ibibio logophors are sensitive
 to two operators in the left periphery of the embedded CP: a shifting operator and
 a logophoric binding operator. Ibibio indexicals (which do not shift) differ in that
 they are defined to be insensitive to shifting operators. Thus indexical shift requires
 cooperation between the semantics of the indexical and of the shifting operator.
 This proposal in turn expands the predicted typology of possible de se pronouns
 cross-linguistically.
Generalized activity equations for spiking neural network dynamics

Year: 2013
Subjects: subject: Neurons and Cognition (q-bio.NC)
subject: FOS: Biological sciences

description: Much progress has been made in uncovering the computational capabilities of spiking neural networks. However, spiking neurons will always be more expensive to simulate compared to rate neurons because of the inherent disparity in time scales - the spike duration time is much shorter than the inter-spike time, which is much shorter than any learning time scale. In numerical analysis, this is a classic stiff problem. Spiking neurons are also much more difficult to study analytically. One possible approach to making spiking networks more tractable is to augment mean field activity models with some information about spiking correlations. For example, such a generalized activity model could carry information about spiking rates and correlations between spikes self-consistently. Here, we will show how this can be accomplished by constructing a complete formal probabilistic description of the network and then expanding around a small parameter such as the inverse of the number of neurons in the network. The mean field theory of the system gives a rate-like description. The first order terms in the perturbation expansion keep track of covariances.

description: The fourth industrial revolution (4IR) has led to the raise of smart taxation (taxation). Smart taxation has come up with different technological innovation that eases tax declaration, tax registration, tax payment interactions. These technological innovations in the tax system aim at enhancing tax compliance. The purpose of this study was to examine the effect of Smart taxation on the tax compliance in Rwanda taking RRA as the case study. Descriptive and explanatory research design were used. The study population comprised of 650 employees of RRA headquarter from which 284 samples were selected using Yamane’s formula. Data were collected from both primary and secondary sources using questionnaire and document review methods. Data was analysed using both descriptive and factor analysis. The fitness of the model was tested using both absolute and incremental fitness tools. The findings from the survey revealed that there is a positive and strong correlation between smart taxation and tax compliance as evidenced by multiple R-square of 96. The researchers recommended that Training of the employees and taxpayers in new skills to be able to comfortably use the new technological innovation that comes along with the fourth industrial revolution. Continue educating the taxpayers about the aim of taxation and modes of taxation to enhance tax compliance since tax education influences tax compliance

Year: 2023

description: This research aims to identify factors determining the performance/growth of Micro and Small-scale Enterprises (MSEs) with a special attention to manufacturing, service, construction, agro industry, urban agriculture and textile and garment in Gulelle sub city. The research approach that was followed in this particular study was quantitative. It also adopted a causal research design and data were generated from samples drawn through stratified sampling procedure. Questionnaire was used to collect data from a sample of 312 operators. Data generated using questionnaire were analyzed using descriptive and inferential statistics. The regression analysis revealed that access to finance, technology infrastructure, and government support explained the variation of MSE’s performance. Therefore, there should be a way to enhance the access of MSEs to technology, finance and infrastructure as well as providing them with the needed government support so that their endeavor to grow to medium scale enterprises can be realized in good time.

description: Efficient and effective dry ports are crucial for the economic growth of a landlocked nation like Ethiopia. This study presents the assessment of the performance and the determinants factors for effective and efficient dry port performance by taking the case of Modjo dry port. Primary data were collected from 130 sample customers and 41 sample employees of the dry port, which were selected based on convenience sampling technique. The data were collected using questionnaire and were analyzed using descriptive statistics and ordinal logistics model. STATA software was used to estimate the logistic regression model. The performance of the dry port estimated using pre-defined performance indicators identified for the latent performance dimension, such as human capital, information capital, and size of the dry port, port machinery, infrastructure and reliability. Accordingly, the overall findings showed that the throughput performance of Modjo dry port was found at medium level with inter-month and annual fluctuations. The result of the study further indicated that except human capital and size of the port, information capital, service cost, port machinery, port infrastructure and reliability were functioning at medium level of performance. Human capital was found at low level of performance, whereas the size of the port was functioning at higher level of performance. Apart from this, the regression analysis of the study suggests that except infrastructure and machinery, information capital, human capital, service cost, size of the port and reliability found positive and significant determinants for the performance of the dry port at different levels of intensity and probability levels. The findings study implied that there is a possibility of improving the performance of Modjo dry port through capacitating human resources, ICT infrastructure, the size of the port and reconsidering the service cost and its reliability. Therefore, the study recommends the strategic leadership on the interventions of improving the performance of Modjo dry port.

Resource Efficient Gadgets for Compiling Adiabatic Quantum Optimization Problems

description: We develop a resource efficient method by which the ground-state of an arbitrary k-local, optimization Hamiltonian can be encoded as the ground-state of a (k-1)-local optimization Hamiltonian. This result is important because adiabatic quantum algorithms are often most easily formulated using many-body interactions but experimentally available interactions are generally 2-body. In this context, the efficiency of a reduction gadget is measured by the number of ancilla qubits required as well as the amount of control precision needed to implement the resulting Hamiltonian. First, we optimize methods of applying these gadgets to obtain 2-local Hamiltonians using the least possible number of ancilla qubits. Next, we show a novel reduction gadget which minimizes control precision and a heuristic which uses this gadget to compile 3-local problems with a significant reduction in control precision. Finally, we present numerics which indicate a substantial decrease in the resources required to implement randomly generated, 3-body optimization Hamiltonians when compared to other methods in the literature.

The interaction of ‐ø‐...‐íle with aspectual classes in Nyamwezi
Creators: name: Ponsiano Sawaka Kanijo
Publisher: name: Zenodo
Year: 2019

description: This study investigates different readings of the construction -ø-...-íle resulting
 from the interaction with aspectual classes in Nyamwezi, a Bantu language spoken
 in Tabora, Tanzania. The study is motivated by two observations. Firstly, in previ-
 ous analyses (Maganga & Schadeberg 1992), it was noted that -ø-...-íle in Nyamwezi
 selects few verbs, but the patterns governing its distribution were not identified.
 Secondly, not much has been done on describing the semantics of verbal roots in
 Nyamwezi (and many other Bantu languages), which appears to be a source of vari-
 able temporal interpretations of -ø-...-íle. Based on field data, I show that the first
 main function of -ø-...-íle is that of stativizer. That is, -ø-...-íle picks out a phase
 of an event or the entire event (if the event lacks phasic structure) and presents
 it as a stable, undifferentiated property. -ø-...-íle does so in three different ways,
 which give three different readings: (i) resultative, when it occurs with achieve-
 ments, (ii) general present, which occurs with statives and (iii) a progressive-like
 reading, which occurs with some activity verbs classified as “directed motion verbs”
 in this study. The discussion of the contrast between these readings is informed by
 a progressive form -lɪɪ-. Many other activity verbs do not typically occur with -ø-
 ...-íle. Those that occur with this construction either suggest the change-of-state
 or condition of the verb’s subject (which has the semantic role of patient; patien-
 tive subject) or they are used in a special pragmatic condition where -ø-...-íle is
 coerced. Coercion of -ø-...-íle expresses a contradiction and/or emphasis, which
 can be regarded as a second main function of this construction.

description: Ensuring efficiency is critical for banks to continually play their role of financial intermediary in mobilizing financial resources and channeling towards productive investment ventures. Thus, this study investigates and discusses on the operating efficiency of 61 branches in Berhan bank between years 2015 and 2020. Secondary data from the internal reports of the Bank were used. A non-parametric linear programing model Data Envelop Analysis (DEA) was employed on input variables (personnel expense and other operating expense) and output variables (annual deposit collected) focusing on output-oriented comparison to estimate the operating efficiency of branches. The finding indicates that both technical and scale efficiency of the branches were very low, with an average 31% and 71 %, respectively and it’s below the best practice frontier of 1 (100%). Meanwhile, 99 percent of the branches operating at an increasing economy of scale. Therefore, most of the branches are operating below the best practice production frontiers and they have the capacity to improve productivity by 29 percent. By geographic location, Addis Ababa city branches have relatively better efficiency compared to branches located in other regions. Looking at the seasonality of branches, the seasoned ones have better average efficiency than their newest counterparts. Therefore, it is recommended that the Bank should design effective deposit mobilization strategy that networks potential market segments, implement branch standardization by focusing on selection of appropriate benchmarks, attain the branches’ most productive scale size through the elimination of scale inefficiencies ,with minimal changes to branches ‘scale size ( revise overall planning process), on branch level resource allocation, invest on managerial skill of personnel to improve branch level leadership and launch technology banking.

description: The thermal state of the fluid is governed by the ratio of the thermal and the rest energy. This brings the composition of the fluid into the picture. Although, fluid composed of lighter particles (e.g: electron-positron pair plasma) at same temperature, is more relativistic compared to fluids with finite baryon loading, but this is not necessarily true when baryon poor transonic fluid are compared with each other. It can be shown that the transonic pair-fluid is the least relativistic. This has far reaching consequences on accreting flows around compact objects and are expected to have similar effect on relativistic outflows and explosive events as well.

A closer look at the Akan determiner bi: An epistemic indefinite analysis
Creators: name: Owusu, Augustina Pokua
Publisher: name: Zenodo
Year: 2019

description: This study aims to shed light on the epistemic indefinite interpretation (EI) of the
 Akan (Asante Twi) determiner bi which hitherto had not been discussed in the
 Akan literature. In previous studies, Amfo (2010) and Arkoh (2011) review its ref-
 erential or specific indefinite interpretation. The current study shows that in addi-
 tion to the above interpretation when bi is used, the speaker signals that she does
 not have access to all the information about who or what satisfies the existential
 claim they are making. I employ Aloni (2001) and Aloni & Port’s (2015) theory of
 conceptual covers and methods of identification to determine “knowledge” of a
 referent in a particular context. Conceptual covers are sets of individual concepts
 which exclusively and exhaustively covers the domain of individuals (Aloni 2001).
 I show that the epistemic indefinite analysis and the specificity or referential anal-
 ysis are compatible. When bi is used, the speaker asserts she can name a notewor-
 thy or identifying property about the referent of the NP, which is the referential or
 specificity interpretation. Additionally, she presupposes that she is ignorant about
 further characterizing information about the referent, the epistemic indefinite in-
 terpretation.
Focus in Limbum

Publisher: name: Zenodo
Year: 2019

description: In this paper, we discuss the realization of focus in Limbum (Grassfields Bantu,
 Cameroon), a language which shows a so-far unattested pattern of focus mark-
 ing, where two distinct focus constructions are realized by two different particles,
 á and bá, which express information focus on the one hand and contrastive fo-
 cus on the other. Strikingly, the former is realized by a structurally more complex
 construction (particle + fronting) – the inverse pattern of what is attested cross-
 linguistically (Fiedler et al. 2010; Skopeteas & Fanselow 2009). A biclausal cleft
 structure underlying the á strategy can be argued to be implausible. Instead, we
 adopt a Q/F particle analysis (Cable 2010) which proposes the existence of a par-
 ticle independent of a higher functional head mediating between that head and
 the focused phrase. Limbum provides overt evidence for both, the head and the
 particle.
The Impact of Currency Devaluation on the Ethiopian Economy

Year: 2023

description: Devaluation is one of the most important but controversial trade policies recommended by the IMF for most of the developing countries in restoring the trade balance and increasing real GDP growth. To this end, this study identifies and analyzes the impact of currency devaluation on Ethiopian economic growth with the intervening role of five major macroeconomic indicators namely export, import, inflation rate, FDI, and interest rate using mediation analysis with multiple linear regression using 27 years’ time series data through SPSS software . Because of the quantifiable behavior of the variables, this study has used quantitative approach to fulfill the major objectives of the research. In addition to this; the overall frame work of the study was designed with causal or explanatory method in order to test the cause and effect relationship between the variables. The result showed that devaluation brought high inflation rate which adversely affected both domestic and international market of the country. Moreover, it increased the rate of growth of imports and decreased the rate of growth of exports; this indicated that devaluation does not have a significant impact on Ethiopian economy. Based on the findings, this study suggests a quick structural economic policy reformation in order to tackle the existing problems of the country. Moreover, there is an obvious need to combine monetary policy measures with fiscal policy in order to promote sustained economic development.

Year: 2023

description: This study was designed to assess the major factors affecting the performance of women entrepreneurs in MSEs. A sample of 340 women entrepreneurs engaged in 5 sectors were taken for the study using proportionate stratified sampling procedure. Data were analyzed using the ordinary least square multiple regression method. The results of the study indicated that personal characteristics of women entrepreneurs in MSEs and their enterprise affect their performance. It also showed that lack of owned premises (land) to run their business, lack of access to finance, inadequate access to business training, stiff competition in the market, lack of access to technology and lack of access to raw materials were economic-related factors that affected the performance of women entrepreneurs in MSEs. The study also found that conflicting gender roles or household responsibilities, network with outsiders and social acceptability were the major social-related factors that affected their performances. The Agency supporting MSE should give diligent attention to the correlates of performance of MSEs.

description: We report an extensive study of the properties of carbyne using first-principles calculations. We investigate carbyne's mechanical response to tension, bending, and torsion deformations. Under tension, carbyne is about twice as stiff as the stiffest known materials and has an unrivaled specific strength of up to 7.5*10^7 Nm/kg, requiring a force of ~10 nN to break a single atomic chain. Carbyne has a fairly large room-temperature persistence length of about 14 nm. Surprisingly, the torsional stiffness of carbyne can be zero but can be 'switched on' by appropriate functional groups at the ends. Further, under appropriate termination, carbyne can be switched into a magnetic-semiconductor state by mechanical twisting. We reconstruct the equivalent continuum-elasticity representation, providing the full set of elastic moduli for carbyne, showing its extreme mechanical performance (e.g. a nominal Young's modulus of 32.7 TPa with an effective mechanical thickness of 0.772 A). We also find an interesting coupling between strain and band gap of carbyne, which is strongly increased under tension, from 3.2 to 4.4 eV under a 10% strain. Finally, we study the performance of carbyne as a nanoscale electrical cable, and estimate its chemical stability against self-aggregation, finding an activation barrier of 0.6 eV for the carbyne-carbyne cross-linking reaction and an equilibrium cross-link density for two parallel carbyne chains of 1 cross-link per 17 C atoms (2.2 nm).

description: The launch of the Hinode satellite has allowed for seeing-free observations at high-resolution and high-cadence making it well suited to study the dynamics of quiescent prominences. In recent years it has become clear that quiescent prominences support small-amplitude transverse oscillations, however, sample sizes are usually too small for general conclusions to be drawn. We remedy this by providing a statistical study of transverse oscillations in vertical prominence threads. Over a three-hour period of observations it was possible to measure the properties of 3436 waves, finding periods from 50 to 6000 s with typical velocity amplitudes ranging between 0.2 to 23 km s$^{-1}$. The large number of observed waves allows the determination of the frequency dependence of the wave properties and derivation of the velocity power spectrum for the transverse waves. For frequencies less than 7 mHz, the frequency-dependence of the velocity power is consistent with the velocity power spectra generated from observations of the horizontal motions of magnetic elements in the photosphere, suggesting that the prominence transverse waves are driven by photospheric motions. However, at higher frequencies the two distributions significantly diverge, with relatively more power found at higher frequencies in the prominence oscillations. These results highlight that waves over a large frequency range are ubiquitous in prominences, and that a significant amount of the wave energy is found at higher frequency.

 gates object experiencers in Sereer-Siin – a dialect of Sereer, a West Atlantic lan-
 guage of the Niger Congo family spoken in Senegal. I show that object experiencers
 in Sereer can be classified in two groups according to their syntactic behavior. In
 this study I provide evidence that Sereer experiencers can be used to extend Belletti
 and Rizzi’s traditional classification of experiencers. Using data from Italian, Bel-
 letti and Rizzi have classified object experiencers in two groups. The first one they
 refer to as class II, has a nominative theme and an accusative experiencer whereas
 the second one, class III, has a nominative theme and a dative experiencer. In Sereer,
 like in Italian, different properties of object experiencers account for asymmetries
 noted with respect to constructions like passive, antipassive and nominalization.

description: Учебное пособие призвано способствовать пониманию студентами глубинных процессов, происходящих в сфере современной коммуникации, трансформирующейся под влиянием глобализации, информатизации и цифровизации. В издании рассмотрены различные трактовки коммуникации, понимаемой как форма реализации человеческой активности, вид человеческой деятельности или социальный институт, который организует деятельность включенных в сферу его влияния людей по определенным правилам, формировавшимся столетиями и чрезвычайно трудно поддающимся трансформации. Большое внимание уделено рассмотрению понятия «коммуникативная культура», с помощью которого обозначаются накопленные в сфере коммуникации знания, ценности и нормы, которые проявляют себя, во-первых, в разнообразных философско-идеологических концепциях, задающих смысловые рамки понимания коммуникации, и во-вторых, в технологиях коммуникации, которые обозначены понятием «коммуникационные матрицы». Подготовлено с учетом требований Федерального государственного образовательного стандарта высшего образования. Учебное пособие предназначено для студентов, обучающихся по укрупненной группе специальностей и направлений подготовки 42.00.00 «Средства массовой информации и информационно-библиотечное дело», изучающих дисциплины «Коммуникационный менеджмент», «Основы медиакультуры», «Основы теории коммуникации», «Психология массовых коммуникаций», «Социология массовых коммуникаций», а также будет полезно студентам других специальностей и направлений подготовки высшего образования, учебными планами которых предусмотрено изучение данных курсов.
Phase retrapping in a pointlike $φ$ Josephson junction: the Butterfly effect

description: We consider a $φ$ Josephson junction, which has a bistable zero-voltage state with the stationary phases $ψ=\pmφ$. In the non-zero voltage state the phase "moves" viscously along a tilted periodic double-well potential. When the tilting is reduced quasistatically, the phase is retrapped in one of the potential wells. We study the viscous phase dynamics to determine in which well ($-φ$ or $+φ$) the phase is retrapped for a given damping, when the junction returns from the finite-voltage state back to zero-voltage state. In the limit of low damping the $φ$ Josephson junction exhibits a butterfly effect --- extreme sensitivity of the destination well on damping. This leads to an impossibility to predict the destination well.

description: We discuss how the interaction between the electrons in a relativistic jet and the Cosmic Microwave Background (CMB) affects the observable properties of radio-loud AGN at early epochs. At high z the magnetic energy density in the radio lobes of powerful radio-loud quasars can be exceeded by the energy density of the CMB (because of its (1+z)^4 dependance). In this case, relativistic electrons cool preferentially by scattering off CMB photons, rather than by synchrotron. Thus, sources sharing the same intrinsic properties have different extended radio and X-ray luminosities when located at different z: more distant sources are less luminous in radio and more luminous in X-rays than their closer counterparts. Instead, in compact regions where the local magnetic field still exceeds the CMB in terms of energy density, synchrotron radiation would be unaffected by the presence of the CMB. Such regions include the compact inner jet and the so-called hot spots in the radio lobes. The decrease in radio luminosity is larger in misaligned sources, whose radio flux is dominated by the extended isotropic component. These sources can fail detection in current flux limited radio surveys, and therefore they are possibly under-represented in the associated samples. As the cooling time is longer for lower energy electrons, the radio luminosity deficit due to the CMB photons is less important at low radio frequencies. Therefore objects not detected so far in current surveys at a few GHz could be picked up by low frequency deep surveys, such as LOFAR and SKA. Until then, we can estimate the number of high redshift radio-loud AGNs through the census of their aligned proxies, i.e., blazars. Indeed, their observed radio emission arises in the inner and strongly magnetized compact core of the relativistic jet, and not affected by inverse Compton scattering off CMB photons.

description: Though the modern study of servant leadership may be traced to the revolutionary work of Greenleaf in late 20th, the concept of servant leadership can be traced back to the 4th century. The servant leadership model as proposed by Robert Greenleaf is suitable to providing employees with the empowerment and participatory job features that are related to both employee and customer satisfaction. This study assessed the level of practice of servant leadership and its relation with employee job satisfaction. The study involved all professional employees of Compassion International in Ethiopia including senior and middle level leadership of the organization. Descriptive as well as inferential statistics were employed to analyze the quantitative data collected. The findings from both quantitative and qualitative data analysis indicated that servant leadership style is practiced well at the organization and the organization is categorized as servant-oriented organization based on the Organizational Leadership Assessment tool. Moreover, it was noted that the level of employee job satisfaction of the organization is very high (94%) and it is exemplary for other likeminded organizations. A positive relationship of job satisfaction with the overall practice of servant leadership style and that of the five dimensions of servant leadership was observed. In addition, respondents’ organizational position, department, sex, service of year and age had significant associations with employee job satisfaction and the level of practice of servant leadership dimensions. Finally, it was concluded that the leadership of this organization has proven and set the example of practice of servant leadership in Ethiopia.

description: In this days project management knowledge and practices becomes very essential due to the fact that managing projects have been emerged complex and challenging from time to time. However, in Ethiopia, very little is studied about critical project success factors, measuring criteria, project management knowledge areas, tools and techniques. The aim of this study is to assess the critical success factors and challenges of the overall railway construction project success in Ethiopia. The study design was explanatory. Mixed approach was used and both primary and secondary data were collected using questionnaires. A sample of 79 respondents was selected from a population of 264. The study findings show that project success factors such as: leadership effectiveness, project team, Contractors. Competency, cost Management, communication management, time management, quality management, risk management, and stakeholder participation respectively are found to be critical factors to the project success. The study also concluded that the major challenging failure factors were: investment cost, skilled manpower in the sector, project integration and stakeholder management, contract administration, and land topography. Thus, it is recommended that participation of relevant stakeholders such as: a farmer on the road sides, people to be displaced and others that may be affected by the project is very essential for successful completion of projects. The Ethiopian Railway Corporation should give emphasis on improving contract administration practices, integration project activities, and improving the project quality management activities. In addition to this, Success factors that have significant effect on the overall success of the railway project should be managed selectively according to their effects.

Complement clause C-agreement beyond subject phi-agreement in Ikalanga
Creators: name: Letsholo, Rose

Publisher: name: Zenodo
Year: 2019

description: In this essay, we provide a rich description and analysis of C-agreement and complement clause complementizer (CCC) distributions in Ikalanga which reveals a highly articulated set of relationships between matrix clause properties and the morphology of an agreeing complementizer. In particular, we show that the agreeing CCC is sensitive not only to matrix subject phi-features, but to matrix voice and tense as well. Although the agreeing Cs are limited to a small set of predicates that are not fully predictable from meaning, the agreement facts are the same wherever an agreeing C is possible.

description: Mixing mechanisms bring the Li from the base of the convective zone to deeper and warmer layers where it is destroyed. These mechanisms are investigated by comparing observations of Li abundances in stellar atmospheres to models of stellar evolution. Observations in open cluster are especially suitable for this comparison, since their age and metallicity are homogeneous among their members and better determined than in field stars. In this work, we compare the evolution of Li abundances in three different clusters: the Hyades, NGC752, and M67. Our models are calculated with microscopic diffusion and transport of chemicals by meridional circulation, and calibrated on the Sun. These comparisons allow us to follow the evolution of Li abundance as a function of stellar mass in each cluster and as a function of the age by comparing this evolution in each cluster. We evaluate the efficiency of the mixing mechanisms used in the models, and we try to identify the lacking mechanisms to reproduce the observed evolution of Li abundance.
