Challenges and Opportunities of Experiential Learning at Institute of Leadership and Good Governance: The Case of Internship Programs
Creators: name: Mehari, Abrehet
Publisher: name: African Journal of Leadership and Development
Year: 2018

description: The purpose of the study was to identify and examine the opportunities and challenges of internships at the federal and regional governments of Ethiopia. The study used both quantitative and qualitative research approaches. The sample size of the study includes 154 students and 73 mentors totaling 227 respondents. Data was collected through questionnaires, interviews, observation, and focused group discussions. Data were analyzed using descriptive statistics. Findings of the study indicate that the critical challenge of the program lies in the mentor's commitment and willingness to support mentees, weak communication among the University, ministry of public service and human resource development, and hosting organizations, lack of a clear understanding and shared vision regarding the program and shortage of time allocated for the program. Thus, the overall assessment of the internship program is not achieving its objectives. Therefore, the policymaker should be aware of the hosting organization and the university to have a clear idea of the internship objectives, and training should be organized for the public sector's employees to understand the advantage of the program and become actors in its implementation. The guideline of internship is better to be utilized properly by all stockholders and assessing the possible gaps through periodic consultative meetings, and forums. Also involving in the materialization and revised the curriculum of the program. Mentees should develop a creative and positive attitude implementing the internship to learn from the process and arm themselves with the spirit that transforms challenges into an opportunity to grow.

description: The structure of plasma flows in close binary systems in which one of the components is a rapidly rotating magnetic white dwarf is studied. The main example considered is the AE Aquarii system; the spin period of the white dwarf is about a factor of 1000 shorter than the orbital period, and the magnetic field on the white dwarf surface is of order of 50 MG. The mass transfer in this system was analyzed via numerical solution of the system of MHD equations. These computations show that the magnetic field of the white dwarf does not significantly influence the velocity field of the material in its Roche lobe in the case of laminar flow regime, so that the field does not hinder the formation of a transient disk (ring) surrounding the magnetosphere. However, the efficiency of the energy and angular momentum exchange between the white dwarf and the surrounding material increases considerably with the development of turbulent motions in the matter, resulting in its acceleration at the magnetospheric boundary and further escape from the system at a high rate. The time scales of the transition of the system between the laminar and turbulent modes are close to those of the AE\,Aqr transition between its quiet and active phases.

description: We review the uncertainties in high-z star-formation rate (SFR) measures and the constraints that one obtains from high-z gamma-ray burst (GRB) rates on them. We show that at the present time, the GRB rates per unit star-formation at z>3 are higher than at lower redshift. We also compare metallicity predictions made using a hierarchical model of cosmic chemical evolution based on two recently proposed SFRs, one based on the observed galaxy luminosity function at high redshift and one based on the GRB rate and find that within the considerable scatter in metal abundance measures, they both are consistent with the data. Analyzing the ensemble of different measurements together, we conclude that despite metallicity biases, GRBs may be a less biased probe of star-formation at z>3 than at z<2. There is likely to be a common origin to the high GRB rate per unit star-formation and the high observed Lyman-continuum production rate in high redshift galaxies and that this may be due to a relative overabundance of stars with mass $>$25Msun which are likely GRB progenitors. We also find that to reconcile these measurements with the Thomson scattering cross section of cosmic microwave background (CMB) photons measured by Planck, the escape fraction of Lyman-continuum photons from galaxies must be low, about 15 percent or less and that the clumping factor of the IGM is likely to be small, about 3. Finally, we demonstrate that GRBs are unique probes of metallicity evolution in low-mass galaxy samples and that GRB hosts likely lost a significant fraction of metals to the intergalactic medium (IGM) due to feedback processes such as stellar winds and supernovae.

We derive separation of variables relations for asymptotic representations in the Grothendieck ring of this category. Baxter $Q$-operators are obtained as transfer matrices for asymptotic representations and obey $TQ$-relations as a consequence of the relations in $K_0(\mathcal O)$.

description: The livestock agriculture industry must adapt to the growing global population by utilizing modern and digital technologies to produce more livestock products more efficiently, all the while addressing concerns about public health, environmental sustainability, and animal welfare. Biometric sensors, big data, block chain technology, electronic sensors, measuring devices, electronic controls, electronic data-processing options, and robotics in ruminant farming dairy cattle, dairy goats, and meat sheep are examples of technologies used in livestock farming (PLF) (Neethirajan and Kemp, 2021). Additionally, the use of smartphone apps for barn monitoring on chicken farms and electronic ear tags for pigs were evaluated (Groher et al., 2020). This involves managing herd movements, tracking grazing patterns, and optimizing feed supply through the use of automated devices and GPS technology. Another is that increased productivity in cattle production is also a result of advances in breeding and genetics. With the use of genomic information, farmers can now make more educated breeding decisions that result in animals with increased growth rates, feed efficiency, and resistance to illness. Simple to use sensors and measuring tools, like those used in milking parlour’s, were more common than data processing tools, such those for illness detection. Farmers can use biometric sensors, which can be either invasive or non-invasive, to track an individual animal's activity and health in real time. This data can then be integrated for population-level analysis. Block chain technology with sensors enabled provides safe and guaranteed traceability of animal products from farm to table, which is crucial for tracking disease outbreaks, averting associated financial losses, and averting food-related health pandemics. With the help of all technologies improve production in livestock and poultry and farmers may make the efficient use of their resources, land and increasing output.  Due to use of these technologies produce less negative impact on the environment.

description: Graphene is ideally suited for photonic and optoelectronic applications, with a variety of photodetectors (PDs) in the visible, near-infrared (NIR), and THz reported to date, as well as thermal detectors in the mid-infrared (MIR). Here, we present a room temperature-MIR-PD where the pyroelectric response of a LiNbO3 crystal is transduced with high gain (up to 200) into resistivity modulation for graphene, leading to a temperature coefficient of resistance up to 900%/K, two orders of magnitude higher than the state of the art, for a device area of 300x300um2. This is achieved by fabricating a floating metallic structure that concentrates the charge generated by the pyroelectric substrate on the top-gate capacitor of the graphene channel. This allows us to resolve temperature variations down to 15umK at 1 Hz, paving the way for a new generation of detectors for MIR imaging and spectroscopy

description: The Gaia Data Release 1 (DR1) sample of white dwarf parallaxes is presented, including 6 directly observed degenerates and 46 white dwarfs in wide binaries. This data set is combined with spectroscopic atmospheric parameters to study the white dwarf mass-radius relationship (MRR). Gaia parallaxes and G magnitudes are used to derive model atmosphere dependent white dwarf radii, which can then be compared to the predictions of a theoretical MRR. We find a good agreement between Gaia DR1 parallaxes, published effective temperatures (Teff) and surface gravities (log g), and theoretical MRRs. As it was the case for Hipparcos, the precision of the data does not allow for the characterisation of hydrogen envelope masses. The uncertainties on the spectroscopic atmospheric parameters are found to dominate the error budget and current error estimates for well-known and bright white dwarfs may be slightly optimistic. With the much larger Gaia DR2 white dwarf sample it will be possible to explore the MRR over a much wider range of mass, Teff, and spectral types.

description: The Purpose of this study was to assess the roles of selected public and private mass media in promoting government responsiveness and the challenges faced when they disseminated information related to government responsiveness. The study was conducted in four selected public and private media sectors. Ana broadcasting corporate and reporter newspaper from private, and Ethiopian Broadcasting Corporation and Addis Zemen newspaper from publicly owned media institutions. The study employed qualitative and quantitative research approach. Quantitative data were collected through questionnaire and qualitative data were collected through in-depth interview. Stratified multi stage sampling followed by proportional and random sampling techniques was used to select the 179 survey journalists and purposive sampling technique was applied to select interviewee. The study revealed that media in Ethiopia play their own role in bringing a variety of government responsiveness issues to the attention of the public and the government. The roles of the Ethiopian media as a watch dog and a civic forum role failed in the range of low level while the agenda setting role was found at a moderate level. The challenges faced the media in reporting government responsiveness in Ethiopia is associated with political, institutional, legal, skill and capacity of the journalists.

description: Recently, Tao and Mo (TM) proposed an accurate all-purpose nonempirical meta-generalized gradient approximation (meta-GGA). The exchange part was derived from the density matrix approximation, while the correlation part is based on a modification of TPSS correlation in the low-density or strong-interaction limit. To further understand this density functional, we combine the TM exchange part with the original TPSS correlation and make a comprehensive assessment of this combination, which we call TMTPSS functional, on solids and solid surfaces. Our test includes 22 lattice constants and bulk moduli, 30 band gaps of semiconductors, 7 cohesive energies, and surface exchange-correlation energies for rs ranging from 2 to 3 bohr. Our calculations show that TMTPSS functional is quite competitive to the TM meta-GGA functional, improving upon the nonempirical functionals LSDA, PBE GGA, and TPSS meta-GGA for most properties considered. In particular, it significantly improves the surface exchange-correlation energy calculation, with a mean absolute error of only 1 erg/cm2.

description: A novel long period grating (LPG) inscribed balloon-shaped heterocore-structured plastic optical fibre (POF) sensor is described and experimentally demonstrated for real-time measurement of the ultra-low concentrations of ethanol in microalgal bioethanol production applications. The heterocore structure is established by coupling a 250 µm core diameter POF between two 1000 µm diameter POFs, thus representing a large core—small core—large core configuration. Before coupling as a heterocore structure, the sensing region or small core fibre (SCF; i.e., 250 µm POF) is modified by polishing, LPG inscription, and macro bending into a balloon shape to enhance the sensitivity of the sensor. The sensor was characterized for ethanol–water solutions in the ethanol concentration ranges of 20 to 80 %v/v, 1 to 10 %v/v, 0.1 to 1 %v/v, and 0.00633 to 0.0633 %v/v demonstrating a maximum sensitivity of 3 × 106 %/RIU, a resolution of 7.9 × 10−6 RIU, and a limit of detection (LOD) of 9.7 × 10−6 RIU. The experimental results are included for the intended application of bioethanol production using microalgae. The characterization was performed in the ultra-low-level ethanol concentration range, i.e., 0.00633 to 0.03165 %v/v, that is present in real culturing and production conditions, e.g., ethanol-producing blue-green microalgae mixtures. The sensor demonstrated a maximum sensitivity of 210,632.8 %T/%v/v (or 5 × 106 %/RIU as referenced from the RI values of ethanol–water solutions), resolution of 2 × 10−4 %v/v (or 9.4 × 10−6 RIU), and LOD of 4.9 × 10−4 %v/v (or 2.3 × 10−5 RIU). Additionally, the response and recovery times of the sensor were investigated in the case of measurement in the air and the ethanol-microalgae mixtures. The experimentally verified, extremely high sensitivity and resolution and very low LOD corresponding to the initial rate of bioethanol production using microalgae of this sensor design, combined with ease of fabrication, low cost, and wide measurement range, makes it a promising candidate to be incorporated into the bioethanol production industry as a real-time sensing solution as well as in other ethanol sensing and/or RI sensing applications.

description: Context. Material processed by the CNO cycle in stellar interiors is enriched in 17O. When mixing processes from the stellar surface reach these layers, as occurs when stars become red giants and undergo the first dredge up, the abundance of 17O increases. Such an occurrence explains the drop of the 16O/17O observed in RGB stars with mass larger than 1.5 M_\solar. As a consequence, the interstellar medium is continuously polluted by the wind of evolved stars enriched in 17O . Aims. Recently, the Laboratory for Underground Nuclear Astrophysics (LUNA) collaboration released an improved rate of the 17O(p,alpha)14N reaction. In this paper we discuss the impact that the revised rate has on the 16O/17O ratio at the stellar surface and on 17O stellar yields. Methods. We computed stellar models of initial mass between 1 and 20 M_\solar and compared the results obtained by adopting the revised rate of the 17O(p,alpha)14N to those obtained using previous rates. Results. The post-first dredge up 16O/17O ratios are about 20% larger than previously obtained. Negligible variations are found in the case of the second and the third dredge up. In spite of the larger 17O(p,alpha)14N rate, we confirm previous claims that an extra-mixing process on the red giant branch, commonly invoked to explain the low carbon isotopic ratio observed in bright low-mass giant stars, marginally affects the 16O/17O ratio. Possible effects on AGB extra-mixing episodes are also discussed. As a whole, a substantial reduction of 17O stellar yields is found. In particular, the net yield of stars with mass ranging between 2 and 20 M_\solar is 15 to 40% smaller than previously estimated. Conclusions. The revision of the 17O(p,alpha)14N rate has a major impact on the interpretation of the 16O/17O observed in evolved giants, in stardust grains and on the 17O stellar yields.

description: The efforts to pursue photo detection with extreme performance in terms of ultrafast response time, broad detection wavelength range, and high sensitivity have never been exhausted as driven by its wide range of optoelectronic and photonic applications such as optical communications, interconnects, imaging and remote sensing1. 2D Dirac semimetal graphene has shown excellent potential toward high performance photodetector with high operation speed, broadband response and efficient carrier multiplications benefiting from its linear dispersion band structure with high carrier mobility and zero bandgap2-4. As the three dimensional analogues of graphene, Dirac semimetal Cd3As2 processes all advantages of graphene as a photosensitive material but potentially has stronger interaction with light as bulk material and thus enhanced responsivity5,6, which promises great potential in improving the performance of photodetector in various aspects . In this work, we report the realization of an ultrafast broadband photodetector based on Cd3As2. The prototype metal-Cd3As2-metal photodetector exhibits a responsivity of 5.9 mA/W with response time of about 6.9 ps without any special device optimization. Broadband responses from 0.8 eV to 2.34 eV are measured with potential detection range extendable to far infrared and terahertz. Systematical studies indicate that the photo-thermoelectric effect plays important roles in photocurrent generation, similar to that in graphene. Our results suggest this emerging class of exotic quantum materials can be harnessed for photo detection with high sensitivity and high speed (~145 GHz) in challenging middle/far-infrared and THz range.

title: Reading and reading-related skills in Arabic-English bilingual speakers in the UK and Saudi Arabia for typical children and children with reading difficulties
Creators: name: Alhelfawi, Suhair Husan

description: This thesis examines reading and reading-related skills in typically developing children and children with specific reading difficulties in Grades 3-6 who are learning to read in Arabic and English, as well as monolingual Arabic-speaking children. The children were tested on measures of phonological awareness (PA), rapid automatised naming (RAN) and phonological memory (PM), as well as reading efficiency and reading accuracy. Study 1 investigated Arabic-English biliterate children who attended schools either in the UK or Saudi Arabia. They performed better in English than Arabic on reading efficiency, PA, and RAN tests. Those in the UK showed higher scores than those in Saudi Arabia in English and, surprisingly, in Arabic. However, there was no significant difference between the participants’ reading accuracy and PM scores for English and Arabic. Then, a comparison was performed with Arabic monolingual speaking children who attended private schools. There was a significant difference between the level of Arabic reading efficiency of the biliterate children and monolingual readers. No differences in reading accuracy performance were found between the biliterates and monolinguals. In addition, the monolinguals slightly outperformed the biliterates in the PA and PM tasks, and they completed the RAN (digits and letters) tasks much more quickly. Furthermore, PA and RAN digits, but not PM, were significant predictors of reading word efficiency in Arabic. However, only PA predicted reading accuracy in Arabic. The participants in Study 2 were 28 Arabic-English bilingual children with reading difficulties. Their PA, PM, RAN, reading accuracy and reading efficiency were found to be worse than those of the typically developing children in Study 1, indicating they had impairments in phonological processing. The large differences found between the languages and the country of residence suggest that exposure to language, reading instruction and education system may differentially affect learning to read in English and Arabic.

L’enjeu actuel est d’identifier les sujets à risque de fracture devant bénéficier d’un traitement anti-ostéoporotique. Plusieurs facteurs cliniques permettent d’estimer le risque de fractures et de chute. La densitométrie osseuse est un outil indispensable au diagnostic de l’ostéoporose mais qui est insuffisant à lui seul pour l’évaluation du risque fracturaire. Le trabecular bone score calculé partir des données d’absorptiométrie biphotonique du rachis lombaire, l’index de risque fracturaire FRAX ou encore les marqueurs du remodelage osseux pourraient constituer des outils intéressants pour l’évaluation du risque fracturaire.

description: It is very common to observe nonlinear features in agricultural and ecological systems. For example, in tree crop production, alternate bearing is well known phenomena caused by nonlinear dynamics. Production of single tree of Citrus Unshiu trees is recognized to be driven by a mechanistic process modeled with the so-called "resource budget model", which demonstrates phenomenon of alternate bearing. However, the term of alternative bearing is used not only for an individual tree's production but also for total production of a large sized population of trees. In this paper, we developed noise induced uncoupled dynamics model for population alternate bearing based on Isagi's resource budget model. Based on numerical experiments with the developed model, theoretical possibility of a substantial alternate bearing effect even in a national market was proposed.

The financial innovations of the last decades have led to the emergence of equity index funds that are increasingly popular among investors. From an economic point of view, these funds have a stronger moneyness than contemporary currencies, particularly in terms of scarcity, accumulation practice and natural return. A specific equity index fund, based for example on the MSCI World index, would be therefore a serious candidate to act as a currency in the near future.

description: In this article we examine the dynamics of a colloidal particle driven by a modulated force over a sinusoidal optical potential energy landscape. Coupling between the competing frequencies of the modulated drive and that of particle motion over the periodic landscape leads to synchronisation of particle motion into discrete modes. This synchronisation manifests as steps in the average particle velocity, with mode locked steps covering a range of average driving velocities. The amplitude and frequency dependence of the steps are considered, and compared to results from analytic theory, Langevin Dynamics simulations, and Dynamic Density Functional Theory. Furthermore, the critical driving velocity is studied, and simulation used to extend the range of conditions accessible in experiments alone. Finally, state diagrams from experiment, simulation, and theory are used to show the extent of the dynamically locked modes in two dimensions, as a function of both the amplitude and frequency of the modulated drive.

description: The purpose of the study was to assess the challenges and opportunities of public service delivery in Bole Sub City Trade and Industry sector. To meet the objective of the study, descriptive survey method was employed. To gather the necessary data, questionnaire and interviews were the main instruments employed. The results obtained from the study revealed that majority of the employees are clear about their organization’s mission, vision and shared values. Moreover, most leaders supporting their employees and give on time solution to customers’ complaints. Reform tools such as BSC and Change Army were found to have positive contribution in delivering service. Service standards are set by the sector and most customers have knowledge about it. However, there is a limitation in continuously improving service standards by the sector. Furthermore, lack of capacity building trainings, skill and attitude gaps on employees, shortages of human resource, budget, office furniture, high employee turnover, unfavorable working environment, electric power and interruption and network accessibility are the major challenge of service delivery in sector. Increasing number of customers from time to time in connection with the expansion of the sub city is another factor for not delivering services based on service standards set. Based on the findings and the conclusions it is recommended that the sector needs to build employee capacity, establish motivation system, and alleviate the shortage of human power, budget, office furniture, high employee turnover and unfavorable organizational environment. Besides, it needs to communicate further about standards and the requirements of service, and the office alignment need to be reorganized.

Single-Field Inflation and the Local Ansatz: Distinguishability and Consistency

description: The single-field consistency conditions and the local ansatz have played separate but important roles in characterizing the non-Gaussian signatures of single- and multifield inflation respectively. We explore the precise relationship between these two approaches and their predictions. We demonstrate that the predictions of the single-field consistency conditions can never be satisfied by a general local ansatz with deviations necessarily arising at order $(n_s-1)^2$. This implies that there is, in principle, a minimum difference between single- and (fully local) multifield inflation in observables sensitive to the squeezed limit such as scale-dependent halo bias. We also explore some potential observational implications of the consistency conditions and its relationship to the local ansatz. In particular, we propose a new scheme to test the consistency relations. In analogy with delensing of the cosmic microwave background, one can deproject the coupling of the long wavelength modes with the short wavelength modes and test for residual anomalous coupling.

Tomographic active optical trapping of arbitrarily shaped objects by exploiting 3-D refractive index maps

description: Optical trapping can be used to manipulate the three-dimensional (3-D) motion of spherical particles based on the simple prediction of optical forces and the responding motion of samples. However, controlling the 3-D behaviour of non-spherical particles with arbitrary orientations is extremely challenging, due to experimental difficulties and the extensive computations. Here, we achieved the real-time optical control of arbitrarily shaped particles by combining the wavefront shaping of a trapping beam and measurements of the 3-D refractive index (RI) distribution of samples. Engineering the 3-D light field distribution of a trapping beam based on the measured 3-D RI map of samples generates a light mould, which can be used to manipulate colloidal and biological samples which have arbitrary orientations and/or shapes. The present method provides stable control of the orientation and assembly of arbitrarily shaped particles without knowing a priori information about the sample geometry. The proposed method can be directly applied in biophotonics and soft matter physics.

description: The generation of very high quality electron bunches (high brightness and low energy spread) from a plasma-based accelerator in the three-dimensional blowout regime using self-injection in tailored plasma density profiles is analyzed theoretically and with particle-in-cell simulations. The underlying physical mechanism that leads to the generation of high quality electrons is uncovered by tracking the trajectories of the electrons as they cross the sheath and are trapped by the wake. Details on how the intensity of the driver and the density scale-length of the plasma control the ultimate beam quality are described. Three-dimensional particle-in-cell simulations indicate that this concept has the potential to produce beams with peak brightnesses between $10^{20}$ and $10^{21}$ $\mathrm{A}/\mathrm{m}^2/\mathrm{rad}^2$and with absolute projected energy spreads of $\sim 0.3~\mathrm{MeV}$ using existing lasers or electron beams to drive nonlinear wakefields.

The Influence of Magnetic Field Geometry on the Formation of Close-in Exoplanets
Creators: name: Simon, Jacob B.
Publisher: name: arXiv

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Approximately half of Sun-like stars harbor exoplanets packed within a radius of ~0.3 AU, but the formation of these planets and why they form in only half of known systems are still not well understood. We employ a one-dimensional steady state model to gain physical insight into the origin of these close-in exoplanets. We use Shakura & Sunyaev alpha values extracted from recent numerical simulations of protoplanetary disk accretion processes in which the magnitude of alpha, and thus the steady-state gas surface density, depends on the orientation of large scale magnetic fields with respect to the disk's rotation axis. Solving for the metallicity as a function of radius, we find that for fields anti-aligned with the rotation axis, the inner regions of our model disk often falls within a region of parameter space not suitable for planetesimal formation, whereas in the aligned case, the inner disk regions are likely to produce planetesimals through some combination of streaming instability and gravitational collapse, though the degree to which this is true depends on the assumed parameters of our model. More robustly, the aligned field case always produces higher concentrations of solids at small radii compared to the anti-aligned case. In the in situ formation model, this bimodal distribution of solid enhancement leads directly to the observed dichotomy in exoplanet orbital distances.

description: In most developing countries, childcare falls on women’s shoulders due to their gender role assigned by society. This study investigated the challenges of Ethiopian working mothers towards childcare and its implications on workplace performance in selected higher education institutions (HEIs). To achieve this objective, 343 working mothers from 9 universities, 3 focus group discussions and key informant interviews were included in the study. Mixed method design that combines both quantitative and qualitative data analysis were employed. The findings of the study indicated that working mothers do not have access to childcare facilities both within and outside their university. It was found that childcare incentives were inadequate but informal extended maternity leaves were common. Working mothers at higher learning institutions perceive various challenges related to childcare, and affects their work performance negatively. Daycare facilities and other incentives are recommended for working mothers to create a better working environment and thereby enhance the performance of working mothers, while supporting the development of healthy children.

Year: 2022

description: Short abstract felyx is a generic open-source community software initially funded by ESA to produce satellite-to-in situ matchups or systematic satellite data extraction over predefined areas, in order to support instrument cal/val activities and monitoring of geophysical quantities. After several years of operation, such as for Sentinel-3 SLSTR Sea Surface Temperature (SST) in EUMETSAT, and applications in many different contexts and parameters (wind, altimetry, …), it has been redesigned under European Union's Copernicus programme funding and managed by EUMETSAT, to add new functionalities, and much improved installation, robustness, configuration and monitoring. It comes with a distributed processing framework allowing to run the processing more efficiently over HPC infrastructure or cloud environment in containerised manner. It works natively with all GHRSST products and can use a variety of in situ measurements (drifters, Argo floats and moored buoys from CMEMS, TRUSTED buoys, radiometers from ship4sst, saildrone) including profile data, to produce matchup dataset files with flexible content and full traceability to source measurements.
