Publisher: name: Hertie School

description: We investigate how managers smooth volatility in balance sheets, using the pension accounting change IAS 19R as a shock to balance sheet volatility. This shock increases pension plans’ funding transparency, which is the source of volatility, without targeting actual plan funding. We find that managers adjust funding levels, pension asset allocation and assumptions to mitigate volatility at this source, but also plan settlements increase drastically. The volatility of accruals decreases, whereas volatility of discretionary real decisions increases pointing to managerial decisions to alleviate volatility in balance sheets. The exposure to balance sheet volatility and the relative net costs of related smoothing are cross-sectional predictors of smoothing activities. Overall, we provide evidence consistent with a vast body of pension accounting literature mentioning but not explicitly investigating the transmission of pension plan volatility on firms’ balance sheets. Our findings link this literature with studies on balance sheet management and provide a new angle on the effects of a transparency mandate in (pension) accounting on managerial decision-making.

description: We carried out second-harmonic generation in quasi-phase-matched α-phase lithium niobate channel waveguides realized by proton exchange and surface periodic poling. Owing to a limited ferroelectric domain depth, we could observe the interplay between second-harmonic generation and self-phase modulation due to cascading and cubic effects, resulting in a nonlinear resonance shift. Data reduction allowed us to evaluate both the quadratic nonlinearity in the near infrared as well as the depth of the uninverted domains.
Geospatial water balancing for the South Florida Water Management District

Subjects: subject: Water balance (Hydrology) -- Florida

description: The main objective of this thesis is to create a methodology for calculation the simple water balance proposed by Ron Mireau automatically and within a GIS framework. In the initial part of this project a data model was developed to describe the spatial features of the hydrologic system within the SFWMD. In conjunction with the SFWMD, PBS&J, and CRWR, an Arc Hydro Enterprise Database (AHED) was developed and implemented in a geodatabase design. The AHED is an extension of the Arc Hydro data model. This thesis looked at ways to describe the movement of water through the SFWMD using the defined geodatabase features in the AHED. To describe the movement of water in the SFWMD two new terms were defined: water control unit and water control catchment. A water control unit can be considered the operationally significant portion of the water control unit network, the water bodies control by the SFWMD. A water control catchment is defined as the extent of land surface area that drains into a water control unit. The Hydrologic Flux Coupler is an excellent approach to automating the geospatial water balance method. Once the links between the documented fluxes and flows are established in the Hydrologic Flux Coupler the only additional requirement is to add time series information into the Timeseries table, in the correct format. The data collection time and computation time of the Hydrologic Flux Coupler is reduces compared to the amount of time required to create an Excel spreadsheet. In particular, the Hydrologic Flux Coupler decreases the amount of time for creating visualizations of the time series information. In addition to the development of the geospatial water balance, an additional analysis of the sensitivity of the geospatial water balance was preformed on the C41-A-North water control unit and catchment for an entire year, November 1, 2002 to October 31, 2003. The results of the data evaluation over the C41-A-North produces conclusions in four areas of interest: rainfall; evaporation and evapotranspiration; calculation of Qtrans; and estimation of water surface area

description: Reconstruction of the CMB in the Galactic plane is extremely difficult due to the dominant foreground emissions such as Dust, Free-Free or Synchrotron. For cosmological studies, the standard approach consists in masking this area where the reconstruction is not good enough. This leads to difficulties for the statistical analysis of the CMB map, especially at very large scales (to study for e.g., the low quadrupole, ISW, axis of evil, etc). We investigate in this paper how well some inpainting techniques can recover the low-$\ell$ spherical harmonic coefficients. We introduce three new inpainting techniques based on three different kinds of priors: sparsity, energy and isotropy, and we compare them. We show that two of them, sparsity and energy priors, can lead to extremely high quality reconstruction, within 1% of the cosmic variance for a mask with Fsky larger than 80%.

Rotating Motions and Modeling of the Erupting Solar Polar Crown Prominence on 2010 December 6

description: A large polar-crown prominence composed of different segments spanning nearly the entire solar disk erupted on 2010 December 6. Prior to the eruption, the filament in the active region part splits into two layers: a lower layer and an elevated layer. The eruption occurs in several episodes. Around 14:12 UT, the lower layer of the active region filament breaks apart, one part ejects towards the west, while the other part ejects towards the east, which leads to the explosive eruption of the eastern quiescent filament. During the early rise phase, part of the quiescent filament sheet displays strong rolling motion (observed by STEREO$\_$B) in the clockwise direction (views from east to west) around the filament axis. This rolling motion appears to start from the border of the active region, then propagates towards the east. AIA observes another type of rotating motion: in some other parts of the erupting quiescent prominence the vertical threads turn horizontal, then turn upside down. The elevated active region filament does not erupt until 18:00 UT, when the erupting quiescent filament already reaches a very large height. We develop two simplified three-dimensional models which qualitatively reproduce the observed rolling and rotating motions. The prominence in the models is assumed to consist of a collection of discrete blobs that are tied to particular field lines of a helical flux rope. The observed rolling motion is reproduced by continuous twist injection into the flux rope in Model 1 from the active region side. Asymmetric reconnection induced by the asymmetric distribution of the magnetic fields on the two sides of the filament may cause the observed rolling motion. The rotating motion of the prominence threads observed by AIA is consistent with the removal of the field line dips in Model 2 from the top down during the eruption.

description: The continuous interest in the social network area contributes to the fast development of this field. The new possibilities of obtaining and storing data facilitate deeper analysis of the entire network, extracted social groups and single individuals as well. One of the most interesting research topic is the dynamics of social groups, it means analysis of group evolution over time. Having appropriate knowledge and methods for dynamic analysis, one may attempt to predict the future of the group, and then manage it properly in order to achieve or change this predicted future according to specific needs. Such ability would be a powerful tool in the hands of human resource managers, personnel recruitment, marketing, etc. The social group evolution consists of individual events and seven types of such changes have been identified in the paper: continuing, shrinking, growing, splitting, merging, dissolving and forming. To enable the analysis of group evolution a change indicator - inclusion measure was proposed. It has been used in a new method for exploring the evolution of social groups, called Group Evolution Discovery (GED). The experimental results of its use together with the comparison to two well-known algorithms in terms of accuracy, execution time, flexibility and ease of implementation are also described in the paper.

description: Motherhood and parental leave are frequent causes of worker absences and employment interruptions, yet we know little about their effects on firms. Based on linked employer-employee data from Germany, we examine how more generous leave benefits affect firm-level employment and hiring decisions. Focusing on small- and medium-sized firms, we show that more generous benefits reduce firm-level employment in the short term, which is driven by firms with few internal substitutes for the absent mother. However, firms do not respond to longer expected absences by hiring fewer young women, even when few internal substitutes are available. To rationalise the findings, we show that replacement hiring occurs largely before the expected absence and that firms hire more external replacements when fewer internal substitutes are available. These findings indicate that extended leave does not harm _rms when these can plan for the longer worker absences.

description: We study numerically the relativistic Bondi-Hoyle accretion of an ideal gas onto a Kerr fixed background space-time on the equatorial plane with s-lab symmetry. We use both Kerr-Schild (KS) and Boyer-Lindquist (BL) coordinates. We particularly focus on the study of the flip-flop motion of the shock cone formed when the gas is injected at supersonic speed. The development of the flip-flop instability of the shock cone in the relativistic regime was reported recently for the first time. We reproduce the flip-flop behaviour found in the past when BL coordinates are used, and perform similar numerical experiments using horizon penetrating KS coordinates. We find that when using KS coordinates the shock cone oscillates, however such oscillations are not of the flip-flop type and their amplitude decrease with resolution.

description: The electronic structure of Sr$_3$CuIrO$_6$, a model system for the 5d Ir ion in an octahedral environment, is studied through a combination of resonant inelastic x-ray scattering (RIXS) and theoretical calculations. RIXS spectra at the Ir L$_3$-edge reveal an Ir $t_{2g}$ manifold that is split into three levels, in contrast to the expectations of the strong spin-orbit-coupling limit. Effective Hamiltonian and $ab inito$ quantum chemistry calculations find a strikingly large non-cubic crystal field splitting comparable to the spin-orbit coupling, which results in a strong mixing of the $j_{\mathsf{eff}}=1/2$ and $j_{\mathsf{eff}}=3/2$ states and modifies the isotropic wavefunctions on which many theoretical models are based.

description: Although superconducting nanowire single-photon detectors (SNSPDs) are well studied regarding the detection of infrared/optical photons and keV-molecules, no studies on continuous X-ray photon counting by thick-film detectors have been reported so far. We fabricated a 100 nm thick niobium X-ray SNSPD (an X-SNSPD), and studied its detection capability of photons with keV-energies in continuous mode. The detector is capable to detect photons even at reduced bias currents of 0.4%, which is in sharp contrast to optical thin-film SNSPDs. No dark counts were recorded in extended measurement periods. Strikingly, the signal amplitude distribution depends significantly on the photon energy spectrum.

description: We have investigated the post-merger signatures of red-sequence galaxies in rich Abell clusters at $z \lesssim$ 0.1: A119, A2670, A3330 and A389. Deep images in u', g', r' and medium-resolution galaxy spectra were taken using MOSAIC 2 CCD and Hydra MOS mounted on a Blanco 4-m telescope at CTIO. Post-merger features are identified by visual inspection based on asymmetric disturbed features, faint structures, discontinuous halo structures, rings and dust lanes. We found that ~ 25% of bright (M_r < -20) cluster red-sequence galaxies show post-merger signatures in four clusters consistently. Most (~ 71%) of the featured galaxies were found to be bulge-dominated, and for the subsample of bulge-dominated red-sequence galaxies, the post-merger fraction rises to ~ 38%. We also found that roughly 4% of bulge-dominated red-sequence galaxies interact (on-going merger). A total of 42% (38% post-merger, 4% on-going merger) of galaxies show merger-related features. Compared to a field galaxy study with a similar limiting magnitude (van Dokkum 2005), our cluster study presents a similar post-merger fraction but a markedly lower on-going merger fraction. The merger fraction derived is surprisingly high for the high density of our clusters, where the fast internal motions of galaxies are thought to play a negative role in galaxy mergers. The fraction of post-merger and on-going merger galaxies can be explained as follows. Most of the post-merger galaxies may have carried over their merger features from their previous halo environment, whereas interacting galaxies interact in the current cluster in situ. According to our semi-analytic calculation, massive cluster haloes may very well have experienced tens of halo mergers over the last 4-5 Gyr; post-merger features last that long, allowing these features to be detected in our clusters today.

description: For the symmetric case of space-fractional diffusion processes (whose basic analytic theory has been developed in 1952 by Feller via inversion of Riesz potential operators) we present three random walk models discrete in space and time. We show that for properly scaled transition to vanishing space and time steps these models converge in distribution to the corresponding time-parameterized stable probability distribution. Finally, we analyze in detail a model, discrete in time but continuous in space, recently proposed by Chechkin and Gonchar. Concerning the inversion of the Riesz potential operator $I_0^α$ let us point out that its common hyper-singular integral representation fails for $α= 1. In our Section 2 we have shown that the corresponding hyper-singular representation for the inverse operator $D_0^α$ can be obtained also in the critical (often excluded) case $α= 1$, by analytic continuation

description: We use a global pixel based estimator to identify the axis of the residual Maximum Temperature Asymmetry (MTA) (after the dipole subtraction) of the WMAP 7 year Internal Linear Combination (ILC) CMB temperature sky map. The estimator is based on considering the temperature differences between opposite pixels in the sky at various angular resolutions (4 degrees-15 degrees and selecting the axis that maximizes this difference. We consider three large scale Healpix resolutions (N_{side}=16 (3.7 degrees), N_{side}=8 (7.3 degrees) and N_{side}=4 (14.7 degrees)). We compare the direction and magnitude of this asymmetry with three other cosmic asymmetry axes (αdipole, Dark Energy Dipole and Dark Flow) and find that the four asymmetry axes are abnormally close to each other. We compare the observed MTA axis with the corresponding MTA axes of 10^4 Gaussian isotropic simulated ILC maps (based on LCDM). The fraction of simulated ILC maps that reproduces the observed magnitude of the MTA asymmetry and alignment with the observed αdipole is in the range of 0.1%-0.5%$ (depending on the resolution chosen for the CMB map). The corresponding magnitude+alignment probabilities with the other two asymmetry axes (Dark Energy Dipole and Dark Flow) are at the level of about 1%. We propose Extended Topological Quintessence as a physical model qualitatively consistent with this coincidence of directions.

description: At zero temperature the lowest part of the spectrum of the QCD Dirac operator is known to consist of delocalized modes that are described by random matrix statistics. In the present paper we show that the nature of these eigenmodes changes drastically when the system is driven through the finite temperature cross-over. The lowest Dirac modes that are delocalized at low temperature become localized on the scale of the inverse temperature. At the same time the spectral statistics changes from random matrix to Poisson statistics. We demonstrate this with lattice QCD simulations using 2+1 flavors of light dynamical quarks with physical masses. Drawing an analogy with Anderson transitions we also examine the mobility edge separating localized and delocalized modes in the spectrum. We show that it scales in the continuum limit and increases sharply with the temperature.

Subjects: deliberative democracy

description: Practices of citizen deliberation have become increasingly popular across Western democracies over the past couple of decades. These may take a wide range of forms, each serving different purposes and interests, and producing different outcomes. Mini-publics are among the most common and widely used deliberative democratic innovations: they can be defined as “independent and facilitated group discussions among a (near) random sample of citizens who take evidence from experts and interested parties” (Smith and Setälä 2019: 300). Different types of mini-publics coexist and imply variation in terms of the number of participants, the number of meetings, the planned output and material costs.
 The main objective of this methods brief is to give a short explanation of what mini-publics effectively are, and to identify the challenges and opportunities they entail. While they should not be conceived as the solution to all policy problems and there are no ‘one-size-fits-all’ models of mini-publics, they offer innovative ways to investigate complex issues and how these are understood by citizens. The methods brief introduces a multi-level mini-public experiment (what we dub ‘the REGROUP model’), in which participants in citizens’ juries have the opportunity to formulate policy recommendations on knowledge communication, disinformation, the role of experts in policy-making and political trust at the domestic and European levels.

description: We show the existence of Bogomol'nyi-Prasad-Sommerfield (BPS) magnetic monopoles in a generalized Yang-Mills-Higgs model which is controlled by two positive functions. This effective model, in principle, would describe the dynamics of the nonabelian fields in a chromoelectric media. We check the consistency of our generalized construction by analyzing an explicit case ruled by a real parameter. We also use the well-known spherically symmetric Ansatz to attain the corresponding self-dual equations describing the topological solutions. The overall conclusion is that the new solutions behave around the canonical one, with smaller or greater characteristic length.

description: In this research, the diagnosis of hepatitis disease was made using the decision tree and evolutionary algorithm of Harris Hawks Optimization. HHO algorithm is a population-based and gradient-independent optimization technique. The main idea of the HHO algorithm is the cooperative behavior and chasing style of Harris's falcon in nature, which is known as surprise attack. The effectiveness of the proposed HHO optimizer method, compared to other nature-inspired techniques, was tested on 29 functions and several real-world engineering problems were investigated. The statistical results and comparisons show that the HHO algorithm has very promising and sometimes competitive results compared to other well-known meta-heuristic techniques
A needs assessment of intervention services for students with emotional, social, and behavioral challenges in an Orthodox Jewish high school
Creators: name: Madsen, Benjamin
Publisher: name: No Publisher Supplied
Year: 2022

description: The present study investigated the mental health needs of a Modern Orthodox Jewish High School. The researcher sought to find out what types of emotional, social, and behavioral issues students present in a Modern Orthodox High School, what types of strategies and interventions are currently being used to address these issues, and how effective teachers perceive these strategies to be. The study investigated what additional services teachers would consider to be useful to address the emotional, social and behavioral challenges of students, and what barriers to the effective delivery of mental health teachers perceive. Finally, the study investigated the differences between teachers of religious topics and teachers of secular topics as pertain to their perception of mental health challenges, perception of strategies used, and suggestions of strategies that they think should be implemented. A survey was administered via Qualtrics to all teaching staff (N = 42) via email. Respondents (n = 29) reported that the most concerning mental health challenges they perceived were anxiety, inattention/hyperactivity, family stressors and peer challenges. Teachers reported that the mental health strategies they observed the most were individual counseling/therapy and health and wellness promotion. Teachers perceived individual counseling, group therapy and parent consultation with the school psychologist/guidance staff to be the most effective interventions. Teachers reported that they perceived it would be effective to add screening for emotional/behavioral/social problems, and prevention programs for students with externalizing challenges and internalizing challenges. The main barriers reported by teachers were competing priorities taking precedence over mental health services, challenges with parent consultation, lack of staff training, difficulty identifying children with mental health needs, stigma associated with receiving mental health services. Teachers of religious topics more frequently reported perceiving higher amounts of mental health challenges, though the means were very close. This survey was conducted in the midst of the COVID-19 pandemic, and the divergence of the findings from prior research on the topic may be due to the unique mental health challenges that came about during the pandemic.

title: Constraints on Quasar Emission Properties from the HeII and HI Transverse Proximity Effect
Creators: name: Schmidt, Tobias Marius
Publisher: name: Heidelberg University Library
Year: 2019

description: Bright quasars are powerful sources of ionizing radiation and have profound impact on the Intergalactic Medium. In particular, they create regions with enhanced ionization and therefore reduced Lyman α forest absorption in their surroundings. Observing this so-called transverse proximity effect along background sightlines provides a view of the foreground quasar from different vantage points, and hence at different lookback times compared to the line-of-sight
toward Earth. One can thus constrain the emission history (lifetime, age) and emission geometry (obscuration, opening angle) of the foreground quasar based purely on geometric and light travel time arguments. Both quantities are so far poorly constrained by observations but fundamental for the understanding of Active Galactic Nuclei. To investigate the HeII transverse proximity effect, we conducted an optical spectroscopic foreground quasar survey around 22 HST/COS sightlines, leading to a sample of 20 foreground quasars. We find statistical evidence for the the HeII transverse proximity effect and infer a constraint on the quasar lifetime of > 25 Myr. From a detailed modeling, based on cosmological hydrodynamical simulations and a dedicated photoionization model including quasar obscuration and finite quasar lifetime, we derive joint constraints on age and obscuration of individual objects, indicating that one quasar is old and unobscured (tage ≈ 25 Myr, Ωobsc < 30 %)
while three other are either young (tage < 10 Myr) or highly obscured (Ωobsc > 70 %). However, the models also reveal that the large scatter intrinsic to the HeII Lyα forest prohibits further progress in the field. I therefore developed a novel method that uses large numbers of HI Lyα forest spectra to map the 3D light echo of individual quasars. An end-to-end test confirms that such tomographic
observations can constrain the age of hyperluminous quasars to better than 20%, requiring only 1 – 2 nights on existing 8 – 10 m facilities. The method bears potential to also constrain the quasar emission geometry and the full lightcurve over the past 100 Myr, rendering it a viable tool to investigate quasar properties.

description: To recognize an object in an image, the user must apply a combination of operators, where each operator has a set of parameters. These parameters must be well adjusted in order to reach good results. Usually, this adjustment is made manually by the user. In this paper we propose a new method to automate the process of parameter adjustment for an object recognition task. Our method is based on reinforcement learning, we use two types of agents: User Agent that gives the necessary information and Parameter Agent that adjusts the parameters of each operator. Due to the nature of reinforcement learning the results do not depend only on the system characteristics but also on the user favorite choices.

description: We considered the interaction of semiconductor quantum register with noisy environment leading to various types of qubit errors. We analysed both phase and amplitude decays during the process of electron-phonon interaction. The performance of quantum error correction codes (QECC) which will be inevitably used in full scale quantum information processors was studied in realistic conditions in semiconductor nanostructures. As a hardware basis for quantum bit we chose the quantum spatial states of single electron in semiconductor coupled double quantum dot system. The modified 5- and 9-qubit quantum error correction (QEC) algorithms by Shor and DiVincenzo without error syndrome extraction were applied to quantum register. 5-qubit error correction procedures were implemented for Si charge double dot qubits in the presence of acoustic phonon environment. Chi-matrix, Choi-Jamiolkowski state and measure of decoherence techniques were used to quantify qubit fault-tolerance. Our results showed that the introduction of above quantum error correction techniques at small phonon noise levels provided quadratic improvement of output error rates. The efficiency of 5-qubits quantum error correction algorithm in semiconductor quantum information processors was demonstrated.

description: We present a microscopic calculation of the complete quasiparticle interaction, including central as well as noncentral components, in neutron matter from high-precision two- and three-body forces derived within the framework of chiral effective field theory. The contributions from two-nucleon forces are computed in many-body perturbation theory to first and second order (without any simplifying approximations). In addition we include the leading-order one-loop diagrams from the N2LO chiral three-nucleon force, which contribute to all Fermi liquid parameters except those associated with the center-of-mass tensor interaction. The relative-momentum dependence of the quasiparticle interaction is expanded in Legendre polynomials up to L=2. Second-order Pauli blocking and medium polarization effects act coherently in specific channels, namely for the Landau parameters f_1, h_0 and g_0, which results in a dramatic increase in the quasiparticle effective mass as well as a decrease in both the effective tensor force and the neutron matter spin susceptibility. For densities greater than about half nuclear matter saturation density ρ_0, the contributions to the Fermi liquid parameters from the leading-order chiral three-nucleon force scale in all cases approximately linearly with the nucleon density. The largest effect of the three-nucleon force is to generate a strongly repulsive effective interaction in the isotropic spin-independent channel. We show that the leading-order chiral three-nucleon force leads to an increase in the spin susceptibility of neutron matter, but we observe no evidence for a ferromagnetic spin instability in the vicinity of the saturation density ρ_0. This work sets the foundation for future studies of neutron matter response to weak and electromagnetic probes with applications to neutron star structure and evolution.

Coherent forward scattering of starlight by a cloud of atomic hydrogen

description: Theory predicts that a plane wave scattered by a thin slab of gas yields, in the forward direction and under specific circumstances, a larger irradiance than would be observed in the absence of the gas. This enhanced Rayleigh scattering depends on the size of the Fresnel zones at the slab location, as seen from the observer's position, and results from the coherence of the scattering. On astronomical scales the exceptional size of Fresnel zones (~1500km) has particular relevance when considering forward-scattered starlight by an interstellar cloud of atomic hydrogen.

description: We investigate, in the transverse traceless (TT) gauge, the generation of the relic background of gravitational waves, generated during an early inflationary stage, on the framework of a large-scale repulsive gravity model. We calculate the spectrum of the tensor metric fluctuations of an effective 4D Schwarzschild-de-Sitter metric, which is obtained after implementing a planar coordinate transformation on a 5D Ricci-flat metric solution, in the context of a non-compact Kaluza-Klein theory of gravity. We found that the spectrum is nearly scale invariant under certain conditions. One interesting aspect of this model is that is possible to derive dynamical field equations for the tensor metric fluctuations, valid not just at cosmological scales, but also at astrophysical scales, from the same theoretical model. The astrophysical and cosmological scales are determined by the gravity- antigravity radius, which is a natural length scale of the model, that indicates when gravity becomes repulsive in nature.
