description: Although the egg capsule plays a crucial role in the embryonic development of cephalopods, its ability to protect embryos from Ultraviolet (UV) radiation is unknown. Our study evaluated the photoprotection mechanisms of S. officinalis to UV-B radiation and estimated the ability of the black capsule to act as a physical shield against it. Embryos with (BC) and without capsule and juveniles were exposed to four experimental UVB conditions for 55 days. The effects of different UVB doses were evaluated in terms of morphological abnormalities and differences in gene expression between each group. We observed that the development might be severely impaired in embryos exposed to UVB without capsule protection, and these effects were time- and UVB-dose-dependent. In addition, we found variations in gene expression levels (light-sensitive, stress response and DNA repair) in different tissues as a function of UVB doses. We suggest a relationship between morphological abnormalities and the limit of molecular regulation. These results suggest that the quantitative differences in expression are essential for defining the survivability of the embryo face to UVB. Thus, we demonstrated that the egg capsule could ensure successful embryonic development of the cuttlefish S. officinalis even at high doses of UVB.

description: In quantum many-body systems with a U(1) symmetry, such as the particle number conservation and the axial spin conservation, there are two distinct types of excitations: charge-neutral excitations and charged excitations. The energy gaps of these excitations may be independent with each other in strongly correlated systems. The static susceptibility of the U(1) charge vanishes when the charged excitations are all gapped, but its relation to the neutral excitations is not obvious. Here we show that a finite excitation gap of the neutral excitations is, in fact, sufficient to prove that the charge susceptibility vanishes (i.e. the system is incompressible). This result gives a partial explanation on why the celebrated quantization condition $n(S-m_z)\in\mathbb{Z}$ at magnetization plateaus works even in spatial dimensions greater than one.

description: Modern facilities are poised to tackle fundamental questions within the Standard Model, aiming to reveal the nature of confinement, its relationship to dynamical chiral symmetry breaking (DCSB) - the origin of visible mass - and the connection between these two, key emergent phenomena. There is strong evidence to suggest that they are intimately connected with the appearance of momentum-dependent masses for gluons and quarks in QCD, which are large in the infrared: $m_g \sim 500\,$MeV and $M_q\sim 350\,$MeV. DCSB, expressed in the dynamical generation of a dressed-quark mass, has an enormous variety of verifiable consequences, including an enigmatic result that the properties of the (almost) massless pion are the cleanest expression of the mechanism which is responsible for almost all the visible mass in the Universe. This contribution explains that these emergent phenomena are expressed with particular force in the partonic structure of hadrons, e.g. in valence-quark parton distribution amplitudes and functions, and, consequently, in numerous hadronic observables, so that we are now in a position to exhibit the consequences of confinement and DCSB in a wide range of hadron observables, opening the way to empirical verification of their expression in the Standard Model.

description: Die Auseinandersetzung mit Funktionen ist einer der wichtigsten Themenstränge des Mathematikunterrichts der Sekundarstufen. Schülerinnen und Schüler sollen im Laufe ihrer Schulzeit den Funktionsbegriff erfassen, wichtige Funktionstypen und ihre Eigenschaften kennen lernen und schließlich Funktionen benutzen, um Zusammenhänge zu erkennen, zu beschreiben oder herzustellen. Um den Funktionsbegriff zu erfassen ist es notwendig geeignete Grundvorstellungen aufzubauen, auf die beim individuellen Rekonstruktionsprozess des Funktionsbegriffs immer wieder zurückgegriffen werden kann. Diese Grundvorstellungen sollten Erfahrungen zu den drei wesentlichen Aspekten des Funktionsbegriffs Zuordnung, Änderungsverhalten (Kovariation) und Sicht als Ganzes umfassen.

description: Quantum systems lose coherence upon interaction with the environment and tend towards classical states. Quantum coherence is known to exponentially decay in time so that macroscopic quantum superpositions are generally unsustainable. In this work, slower than exponential decay of coherences is experimentally realized in an atom-optics kicked rotor system subjected to non-stationary Lévy noise in the applied kick sequence. The slower coherence decay manifests in the form of quantum subdiffusion that can be controlled through the Lévy exponent. The experimental results are in good agreement with the analytical estimates and numerical simulations for the mean energy growth and momentum profiles of atom-optics kicked rotor.

description: We investigate the detection prospects of a non-standard dark sector in the context of boosted dark matter. We consider a scenario where two stable particles have a large mass difference and the heavier particle accounts for most of dark matter in our current universe. The heavier candidate is assumed to have no interaction with the standard model particles at tree-level, hence evading existing constraints. Although subdominant, the lighter dark matter particles are efficiently produced via pair-annihilation of the heavier ones in the center of the Galaxy or the Sun. The large Lorentz boost enables detection of the non-minimal dark sector in large volume terrestrial experiments via exchange of a light dark photon with electrons or nuclei. Various experiments designed for neutrino physics and proton decay are examined in detail, including Super-K and Hyper-K. In this study, we focus on the sensitivity of the far detector at the Deep Underground Neutrino Experiment for boosted dark matter produced in the center of the Sun, and compare our findings with recent results for boosted dark matter produced in the galactic center.

description: Recent result [Wu and Guo, Comm. Math. Phys., 2015] has shown that over the 2D unit disk, the classical half-space equation (CHS) for the neutron transport does not capture the correct boundary layer behaviour as long believed. In this paper we develop a regularization technique for CHS to any arbitrary order and use its first-order regularization to show that in the case of the 2D unit disk, although CHS misrepresents the boundary layer behaviour, it does give the correct boundary condition for the interior macroscopic (Laplace) equation. Therefore CHS is still a valid equation to recover the correct boundary condition for the interior Laplace equation over the 2D unit disk.

Year: 2018

description: Ethiopia"s Urban Health Extension Program (UHEP) is an innovative government plan to ensure health equity by creating demand for essential health services through the provision of health information at a household level and access to services through referrals to health facilities. The ministry of health has realized there is need for cross-sectorial support for urban health to achieve such an ambitions policy objective. Despite the substantial progress achieved in the UHEP, there have been considerable challenges such as unsatisfactory and inadequate collaboration among sector offices having important roles in implementing UHEP. By the aforementioned problems and the methodological gap the study sought to analyze inter organizational relations in UHEP implementation through policy network analysis. The study utilized social network approach to provide network structure and positon of actors in resource sharing, coordination and partnership networks with in UHEP implementation. The findings were based on 64 sample organizations and reveal that on average UHEP implementation network had resource sharing relationships with 2.9% (low density) and worked in coordination with 27.9% (lower density) and in partnership with 16.2% (low density) of the other UHEP implementers in the network. In the network of resource sharing the most central or influential actor were Woreda Health Office (WHO) and Health Center (HC). The Sub City Health Office (SCHO) has designed as the most central actor in the coordination network by other organizations. Regarding the partnership network, WHO was the most prominent actor in the network. The study conclude that More organizations worked independently towards similar goals while being aware of others work (coordination), than organizations working together as a formal team (partnership). The study also recommended some points to improve inter organizational relation in UHEP implementation such as policy maker should Create fluid boundaries and eliminate barriers for working across organizations, promote private health partnerships.

description: The astrophysical sources responsible for ultra high-energy cosmic rays (UHECRs) continue to be one of the most intriguing mysteries in astrophysics. We present a comprehensive search for correlations between high-energy ($\gtrapprox 1$ GeV) gamma-ray events from the Fermi Large Area Telescope (LAT) and UHECRs ($\gtrapprox 60$ EeV) detected by the Telescope Array and the Pierre Auger Observatory. We perform two separate searches. First, we conduct a standard cross-correlation analysis between the arrival directions of 148 UHECRs and 360 gamma-ray sources in the Second Catalog of Hard Fermi-LAT sources (2FHL). Second, we search for a possible correlation between UHECR directions and unresolved Fermi-LAT gamma-ray emission. For the latter, we use three different methods: a stacking technique with both a model-dependent and model-independent background estimate, and a cross-correlation function analysis. We also test for statistically significant excesses in gamma rays from signal regions centered on Cen A and the Telescope Array hotspot. No significant correlation is found in any of the analyses performed, except a weak ($\lessapprox 2σ$) hint of signal with the correlation function method on scales $\sim 1^\circ$. Upper limits on the flux of possible power-law gamma-ray sources of UHECRs are derived.

description: We discuss phenomenological aspects of models whose scalar sector is extended by an isospin doublet scalar and a complex singlet scalar as an effective theory of supersymmetric models with mixed sneutrinos. In such models, the lighter of the mixed neutral scalars can become a viable dark matter candidate by imposing a U(1) symmetry. We find that the thermal WIMP scenario is consistent with the cosmological dark matter abundance when the mass of the scalar is half of that of the discovered Higgs boson or larger than around 100 GeV. We also point out that, with an additional isospin singlet Majorana fermion mediator, even the mass of the scalar WIMP less than around 5 GeV is compatible with the observed dark matter abundance. We show that such cosmologically allowed regions can be explored at future collider experiments and dark matter detections.

Assessment of Public Debt Management Practice in Ethiopia

description: Ethiopia's external debt stock has risen rapidly and has almost quadrupled even if debt relief was granted under the Heavily Indebted Poor Countries /Multilateral Debt Relief Initiative (HIPC/MDRI) in 2006 and other problems being facilitated. The impact of this debt burden is enormous in economic and human development of Ethiopia which can be observed from the debt overhang. This entails a need for more comprehensive study which rigorously examines public debt management practices in Ethiopia. Hence, the purpose of this study was to assess the debt management strategy and the precise debt management practice of Ethiopia starting from 2002 after Ethiopia restarts debt management practice from ground due to the debt relief and debt cancellation granted by various multilateral and bilateral creditors up to 2011. The research employed a descriptive research analysis which involves both quantitative and qualitative tools to drive concrete findings. In order to extract the necessary information for the study, document review was considered as the major tool for secondary data gathering while primary data was gathered through key informant interview with directors and managers of debt management unit in the Ministry of Finance and Economic Development. In visualizing the major components of Ethiopia's debt management strategy the main objective focuses on debt sustainability analysis and gives less attention to parts of debt management strategy such as, fiscal, legal, institutional and operational measures. Despite the efforts in debt management activities, it is still at nascent stage and not performing at its maximum potential. The major challenges faced by debt management practices includes; shortage of human labor force, minimum skills of negotiating teams as well as those who engaged in monitoring and evaluation process, lack of debt management strategy, inaccessibility of alternative creditors to make a choice, late disbursement made by creditors after loan agreement signing, the inability of the government to fund expenditures from treasury and non existence of past performance evaluation process. According to the debt management directorates study, even if Ethiopia's debt is affordable, the time to time plan of the government necessitating large amount of finance may put risk on future debt capacity

description: We have studied disorder effects on the coefficients of Ginzburg - Landau (GL) expansion for attractive Hubbard model within the generalized DMFT+Sigma approximation for the wide region of the values of attractive potential U - from the weak-coupling limit, where superconductivity is described by BCS model, towards the strong coupling, where superconducting transition is related to Bose - Einstein condensation (BEC) of compact Cooper pairs. For the case of semi-elliptic initial density of states disorder influence on the coefficients A and B before the square and the fourth power of the order parameter is universal for at all values of electronic correlations and is related only to the widening of the initial conduction band (density of states) by disorder. Similar universal behavior is valid for superconducting critical temperature T_c (the generalized Anderson theorem) and specific heat discontinuity at the transition. This universality is absent for the coefficient C before the gradient term, which in accordance with the standard theory of "dirty" superconductors is strongly suppressed by disorder in the weak-coupling region, but can slightly grow in BCS - BEC crossover region, becoming almost independent of disorder in the strong coupling region. This leads to rather weak disorder dependence of the penetration depth and coherence length, as well as the slope of the upper critical magnetic field at T_c, in BCS - BEC crossover and strong coupling regions.

description: Standard approaches to Bayesian parameter inference in large scale structure assume a Gaussian functional form (chi-squared form) for the likelihood. This assumption, in detail, cannot be correct. Likelihood free inferences such as Approximate Bayesian Computation (ABC) relax these restrictions and make inference possible without making any assumptions on the likelihood. Instead ABC relies on a forward generative model of the data and a metric for measuring the distance between the model and data. In this work, we demonstrate that ABC is feasible for LSS parameter inference by using it to constrain parameters of the halo occupation distribution (HOD) model for populating dark matter halos with galaxies. Using specific implementation of ABC supplemented with Population Monte Carlo importance sampling, a generative forward model using HOD, and a distance metric based on galaxy number density, two-point correlation function, and galaxy group multiplicity function, we constrain the HOD parameters of mock observation generated from selected "true" HOD parameters. The parameter constraints we obtain from ABC are consistent with the "true" HOD parameters, demonstrating that ABC can be reliably used for parameter inference in LSS. Furthermore, we compare our ABC constraints to constraints we obtain using a pseudo-likelihood function of Gaussian form with MCMC and find consistent HOD parameter constraints. Ultimately our results suggest that ABC can and should be applied in parameter inference for LSS analyses.

description: People facing material deprivation are more likely to turn to acquisitive crime. It is not clear why it makes sense for them to do so, given that apprehension and punishment may make their situation even worse. Recent theory suggests that people should be more willing to steal if they are on the wrong side of a ‘desperation threshold’; that is, a level of resources critical to wellbeing. Below such a threshold, people should pursue any risky behaviour that offers the possibility of a short route back above, and should be insensitive to the severity of possible punishments, since they have little left to lose. We developed a multi-round, multi-player economic game with a desperation threshold and the possibility of theft as well as cooperation. Across four experiments with 1000 UK and US adults, we showed that falling short of a desperation threshold increased stealing from other players, even when the payoff from stealing was negative on average. Within the microsocieties created in the game, the presence of more players with below-threshold resources produced low trust, driven by the experience of being stolen from. Contrary to predictions, our participants appeared to be somewhat sensitive to the severity of punishment for being caught trying to steal. Our results show, in an experimental microcosm, that some members of society falling short of a threshold of material desperation can have powerful social consequences.

description: This study aims to assessing the role of participation in decision making in improving employees commitment in the case of selected district of Hidasie Telecom Share Company. More particularly, it is aims at mapping out the extent of participation in decision making process and to identify the mechanism employed by the management to ensure employed participation and examine the effect of employees' participation on their commitment. It also aims to investigate challenges associated with employees' participation in decision making. A questionnaire related to employees' participation in decision making and employees' commitment was administered and, categorized into five part, which are demographic information, extent of employees' participation in decision making, mechanism employed by management to ensure participation in decision making, challenges associated with participation in decision making and effect of participative decision making in improving employees commitment. The results revealed that the extent of participation in decision making in HT was below moderate. The mechanism employed by management to ensure participation in decision making is moderate. It was also noted that main challenges associated with participation in decision making are the following; lack of management commitment to participate, managers' belief that decision making is there sole responsibility and the concern of managers of their power and authority is weakened. More over the study found that the effect of participation in decision making on employees commitment was very high. The finding also suggested that extent and mechanism participation in decision making have strong and positive relationship with employees' commitment. Whereas the challenge of participation in decision making have strong and negative relationship with employees commitment. Finally, it has recommended that better Extent and mechanism of employees' participation and the avoidance of challenges associated with participation in decision making would continue to improve the commitment of employees towards organizational goal.

Time Operator in Relativistic Quantum Mechanics

description: It is first shown that the Dirac's equation in a relativistic frame could be modified to allow discrete time, in agreement to a recently published upper bound. Next, an exact self-adjoint $4\times 4$ relativistic time operator for spin-$\frac{1}{2}$ particles is found and the time eigenstates for the non-relativistic case are obtained and discussed. Results confirm the quantum mechanical speculation that particles can indeed occupy negative energy levels with vanishingly small but non-zero probablity, contrary to the general expectation from classical physics. Hence, Wolfgang Pauli's objection regarding the existence of a self-adjoint time operator is fully resolved. It is shown that using the time operator, a bosonic field referred here to as energons may be created, whose number state representations in non-relativistic momentum space can be explicitly found.

description: In the Milky Way there are thousands of stellar clusters each harboring from a hundred to a million stars. Although clusters are common, the initial conditions of cluster formation are still not well understood. To determine the processes involved in the formation and evolution of clusters it is key to determine the global properties of cluster-forming clumps in their earliest stages of evolution. Here, we present the physical properties of 1,244 clumps identified from the MALT90 survey. Using the dust temperature of the clumps as a proxy for evolution we determined how the clump properties change at different evolutionary stages. We find that less-evolved clumps exhibiting dust temperatures lower than 20 K have higher densities and are more gravitationally bound than more-evolved clumps with higher dust temperatures. We also identified a sample of clumps in a very early stage of evolution, thus potential candidates for high-mass star-forming clumps. Only one clump in our sample has physical properties consistent with a young massive cluster progenitor, reinforcing the fact that massive proto-clusters are very rare in the Galaxy.
Die internationalen Schulleistungsstudien PISA 2000 und PISA 2003 im Spannungsfeld zwischen Wissenschaft, Bildungspolitik und Massenmedien

description: Die Untersuchung will Antworten auf die Frage geben, wie von der Bildungsforschung produziertes Wissen in öffentlichen Diskursen außerhalb des Wissenschaftssystems aufgegriffen und gedeutet wird. Als Produkte der Bildungsforschung wurden hierzu die internationalen Schulleistungsstudien PISA 2000 und PISA 2003 ausgewählt. Die Untersuchung geht von der These aus, dass es sich beim öffentlichen Diskurs über die PISA-Studien um einen Transformationsprozess handelt, in dem die Ergebnisse der Bildungsforschung als wissenschaftlich erzeugtes Wissen von anderen gesellschaftlichen Teilsystemen (Politik und Massenmedien) nach deren Systemlogik in neue Wissensformen überführt werden. Das besondere Forschungsziel besteht darin, die entsprechenden Deutungsleistungen der Teilsysteme Politik und Massenmedien zu analysieren und so die Frage zu beantworten, welches „Problem PISA“ am Ende dieses Transformationsprozesses in der Öffentlichkeit stand. Somit will die Untersuchung einen Beitrag zur Aufbereitung der öffentlichen Wahrnehmung der Bildungsforschung und ihrer Wirkungsgeschichte leisten. Das methodische Instrumentarium der Untersuchung ist die qualitative Inhaltsanalyse, die sich auf Zeitungsberichte und Plenardebatten bezieht. Die Untersuchung kommt zu dem Ergebnis, dass der öffentliche Diskurs die Ergebnisse der PISA-Studien in ein politisches und gesellschaftliches Ereignis überführte. Sowohl für das politische System als auch das System Massenmedien konnten zwei Diskurslager nachgewiesen werden, die mit Bezug auf die Ergebnisse der Bildungsforschung ihre Positionen zu Fragen des gesellschaftlichen Zusammenlebens, Werteorientierungen, Ordnungsprinzipien sowie Bildungs- und Erziehungsvorstellungen austauschten. Das Akronym PISA erhielt in diesem Zusammenhang eine Art Symbolcharakter für gesellschaftliche Problemlagen und Fehlentwicklungen unterschiedlicher Art, die von PISA im Zustand der Institution Schule gespiegelt gesehen wurden. Somit ging der öffentliche Diskurs über PISA über die spezifischen Forschungsziele und Ergebnisse der Studien weit hinaus. Dies führte zu einer breiten öffentlichen Darstellung der Bildungsforschung, die aber nicht deren eigener Systemlogik, sondern derjenigen der sich auf sie beziehenden gesellschaftlichen Teilsysteme folgte.
