description: An important outcome of the audit process is the adjustments to the pre-audit financial statements prepared by managers. We provide empirical evidence on the determinants of auditors’ decision to require adjustments to the pre-audit financial statements. We find that clients with higher pre-adjusted discretionary accruals are more likely to receive downward adjustments to pretax income and clients with lower effective tax rates are more likely to receive upward adjustments to taxes payable. However, auditors are less likely to require downward income adjustments when their clients’ pre-adjusted return on equity is just above the critical cutoff that qualifies them for stock listing or new share offering. Our results support the notion that auditors correct for management bias, but not to the extent to cause severe adverse consequences to their clients. Adjustments of both income and tax obligation are also influenced by several attributes of signatory auditors including industry specialization, independence from the client, the rank, and gender of the auditor.

description: Our ability to interact with the world around us relies on being able to infer what actions objects afford -- often referred to as affordances. The neural mechanisms of object-action associations are realized in the visuomotor pathway where information about both visual properties and actions is integrated into common representations. However, explicating these mechanisms is particularly challenging in the case of affordances because there is hardly any one-to-one mapping between visual features and inferred actions. To better understand the nature of affordances, we trained a deep convolutional neural network (CNN) to recognize affordances from images and to learn the underlying features or the dimensionality of affordances. Such features form an underlying compositional structure for the general representation of affordances which can then be tested against human neural data. We view this representational analysis as the first step towards a more formal account of how humans perceive and interact with the environment.

description: We contribute to the long-standing debate among various capital market participants on whether auditing industry practices low-balling (charging low fees) which in turn compromises auditor independence and audit quality. Using a large sample representing years 2000-2006, we first estimate unexpected (abnormal) audit fee as residuals from a regression of audit fee on several determinants of audit fee. Next, we run a regression of going concern opinions and other audit quality measures on unexpected audit fee and control variables. Our results suggest that audit quality is lower when unexpected audit fee is negative, i.e., actual audit fee is less than the expected fee. Further, there is no evidence that audit quality is impaired when unexpected audit fee is positive. These findings are consistent with the notion that when auditors earn excess fees they are mindful of the perceived threat to their independence in appearance and take steps to preserve their reputation capital.
The role of external monitoring in firm valuation : The case of R&D capitalization

Publisher: name: American University

description: We investigate whether the use of a high quality auditor and increased regulatory monitoring of R&D reporting influence both the level of R&D expenditure capitalized by Australian companies from 1992 to 2002 and the market's perception of the reliability of these figures. The results indicate that firms with a higher quality auditor capitalize lower levels of R&D costs and that in the period following increased regulatory monitoring, firms capitalize fewer R&D costs. Analysis of the value relevance of R&D expenditure indicates that the market positively values R&D costs when expensed as incurred. These results are consistent using both price and returns models. Results are less persistent for capitalized R&D amounts. The finding from the returns model indicates that the quality of the auditor appears to enhance the reliability of capitalized R&D costs while the price model suggests that the cumulative R&D asset is less relevant in the period following ASC monitoring.

description: In this article we discuss several aspects of the stochastic dynamics of spin models. The paper has two independent parts. Firstly, we explore a few properties of the multi-point correlations and responses of generic systems evolving in equilibrium with a thermal bath. We propose a fluctuation principle that allows us to derive fluctuation-dissipation relations for many-time correlations and linear responses. We also speculate on how these features will be modified in systems evolving slowly out of equilibrium, as finite-dimensional or dilute spin-glasses. Secondly, we present a formalism that allows one to derive a series of approximated equations that determine the dynamics of disordered spin models on random (hyper) graphs.

description: Nonleptonic $B$ to charmonium decays generally deviate from the factorization predictions. We study rescattering effects mediated by intermediate charmed mesons in this class of decay modes and, in particular, we consider $B^- \to K^- h_c$ with $h_c$ the $J^{PC}=1^{+-}$ $\bar c c$ meson, relating this mode to $B^- \to K^- χ_{c0}$. We find ${\cal B}(B^- \to K^- h_c)$ large enough to be measured at the $B$ factories, hence this process could be used to study the poorly known $h_c$.

The value-relevance of cash flows and accruals : The role of investment opportunities

name: Krishnan, Gopal V.
Publisher: name: American University
Year: 2023

description: We examine how the value-relevance of earnings components – cash flows from operations (CFO), and accruals – varies with investment opportunities. We consider three hypotheses for how CFO and accrual response coefficients (CRCs and ARCs) can vary with IOS. The growth information hypothesis suggests that both CRCs and ARCs increase with IOS because investors infer the abnormal earnings potential of growth opportunities from current earnings surprises. The internal resource hypothesis posits that information asymmetries create a cost wedge between internal and external financing that causes CFO response coefficients (CRCs) to vary directly with IOS and vary more substantially than accrual response coefficients (ARCs). The noisy measure hypothesis proposes that measurement deficiencies cause both CRCs and ARCs to vary inversely with IOS. Using a larger and more representative sample, updated measures, and enhanced model specifications relative to those used in prior studies, we find that both CRCs and ARCs first increase with IOS and then decline. We conduct two additional tests to distinguish between the first two hypotheses. First, we find, conditional on IOS, that CRCs are higher and ARCs lower when investments are intangible intensive. Second, both CRCs and ARCs are higher when liquid resources in excess of normal operating and investing needs are low than when they are high. These findings support the internal resource hypothesis and the noisy measure hypothesis but do not favor the growth information hypothesis. Furthermore, the impact of the internal resource hypothesis dominates at low-IOS levels and for CRCs, while the noisy measure hypothesis dominates at high-IOS levels and for ARCs. The findings have implications for financial analysis and accounting regulation.

description: Additional file 1: Table 1S. Score table. The result obtained by a particular evaluator for a particular case will receive different score according to the difficulty of the diagnosis. Because the degree of difficulty in the diagnosis is not equal in all of the cases, we assigned a different score, ranged between -10 to 40, according to the “difficulty” for diagnosing. For instance, if a patient has a loss of fat because she had anorexia nervosa but the evaluator considered that she suffered any subtype of generalized lipodystrophy, the score will be negative, and the opposite is true, if a patient suffered a extremely infrequent lipodystrophy, with a complicated phenotype (for instance, Wiedemann Rautenstrauch syndrome) and the evaluator achieved a correct diagnose, the score will be high. Then, we add all the scores of each evaluator , transformed in percentage, and compared the results obtained based on his/her on knowledges with those provided by LipoDDX.

description: Atom interferometers (AIs) on earth and in space offer good capabilities for measuring gravitational waves (GWs) in the mid-frequency deciHz band, complementing the sensitivities of the LIGO/Virgo and LISA experiments and enabling probes of possible modifications of the general relativity predictions for GW propagation. We illustrate these capabilities using the projected sensitivities of the AION (terrestrial) and AEDGE (space-based) AI projects, showing that AION could improve the present LIGO/Virgo direct limit on the graviton mass by a factor $\sim 40$ to $\simeq 10^{-24}\,$eV, and AEDGE could improve the limit by another order of magnitude. AION and AEDGE will also have greater sensitivity than LIGO to some scenarios for Lorentz violation.

Structure and Instability of the Ionization Fronts around Moving Black Holes

description: In this paper we focus on understanding the physical processes that lead to stable or unstable ionization fronts (I-fronts) observed in simulations of moving black holes (BHs). The front instability may trigger bursts of gas accretion, rendering the BH significantly more luminous than at steady-state. We perform a series of idealized three dimensional radiation hydrodynamics simulations resolving the I-fronts around BHs of mass $M_\mathrm{BH}$ and velocity $v_\infty$ accreting from a medium of density $n_\mathrm{H}$. The I-front, with radius $R_\mathrm{I}$, transitions from D-type to R-type as the BH velocity becomes larger than a critical value $v_\mathrm{R}\sim 40\,\mathrm{km/s}$. The D-type front is preceded by a bow-shock of thickness $ΔR_\mathrm{I}$ that decreases as $v_\infty$ approaches $v_\mathrm{R}$. We find that both D-type and R-type fronts can be unstable given the following two conditions: i) for D-type fronts the shell thickness must be $ΔR_\mathrm{I}/R_\mathrm{I}<0.05$ (i.e., $v_\infty \gtrsim 20\,\mathrm{km/s}$.), while no similar restriction holds for R-type fronts; ii) the temperature jump across the I-front must be $T_\mathrm{II}/T_\mathrm{I}>3$. This second condition is satisfied if $T_\mathrm{I}<5000\,\mathrm{K}$ or if $n_\mathrm{H}\,M_\mathrm{BH} \gtrsim 10^6\,M_\odot\,\mathrm{cm^{-3}}$. Due to X-ray pre-heating typically $T_\mathrm{I} \sim 10^4\,\mathrm{K}$, unless the D-type shell is optically thick to X-rays, which also happens when $n_\mathrm{H}\,M_\mathrm{BH}$ is greater than a metallicity-dependent critical value. We thus conclude that I-fronts around BHs are unstable only for relatively massive BHs moving trough very dense molecular clouds. We briefly discuss the observational consequences of the X-ray luminosity bursts likely associated with this instability.

description: Star formation activity depends on galactic-scale environments. To understand the variations in star formation activity, comparing the properties of giant molecular clouds (GMCs) among environments with different star formation efficiency (SFE) is necessary. We thus focus on a strongly barred galaxy to investigate the impact of the galactic environment on the GMCs properties, because the SFE is clearly lower in bar regions than in arm regions. In this paper, we present the $^{12}$CO($1-0$) observations toward the western bar, arm and bar-end regions of the strongly barred galaxy NGC1300 with ALMA 12-m array at a high angular resolution of $\sim$40 pc. We detected GMCs associated with the dark lanes not only in the arm and bar-end regions but also in the bar region, where massive star formation is not seen. Using the CPROPS algorithm, we identified and characterized 233 GMCs across the observed regions. Based on the Kolmogorov-Smirnov test, we find that there is virtually no significant variations in GMC properties (e.g., radius, velocity dispersion, molecular gas mass, and virial parameter) among the bar, arm and bar-end region. These results suggest that systematic differences in the physical properties of the GMCs are not the cause for SFE differences with environments, and that there should be other mechanisms which control the SFE of the GMCs such as fast cloud-cloud collisions in NGC1300.

description: In a semiconductor, collective excitations of spin textures usually decay rather fast due to D'yakonov-Perel' spin relaxation. The latter arises from spin-orbit coupling, which induces wave-vector-dependent spin rotations that, in conjunction with random disorder scattering, generate spin decoherence. However, symmetries occurring under certain conditions can prevent the relaxation of particular homogeneous and inhomogeneous spin textures. The inhomogeneous spin texture, termed as persistent spin helix, is especially appealing as it enables us to manipulate the spin orientation while retaining a long spin lifetime. Recently, it was predicted that such symmetries can be realized in zinc-blende two-dimensional electron gases if at least two growth-direction Miller indices agree in modulus and the coefficients of the Rashba and linear Dresselhaus spin-orbit couplings are suitably matched [PRL 117, 236801 (2016)]. In the present paper, we systematically analyze the impact of the symmetry-breaking cubic Dresselhaus spin-orbit coupling, which generically coexists in these systems, on the stability of the emerging spin helices with respect to the growth direction. We find that, as an interplay between orientation and strength of the effective magnetic field induced by the cubic Dresselhaus terms, the spin relaxation is weakest for a low-symmetry growth direction that can be well approximated by a [225] lattice vector. These quantum wells yield a 30\% spin-helix lifetime enhancement compared to [001]-oriented electron gases and, remarkably, require a negligible Rashba coefficient. The rotation axis of the corresponding spin helix is only slightly tilted out of the quantum-well plane. This makes the experimental study of the spin-helix dynamics readily accessible for conventional optical spin orientation measurements where spins are excited and detected along the quantum-well growth direction.

description: We show that gender inequality decreases the variety of goods countries produce and export, in particular in low-income and developing countries. We argue that this happens through at least two channels: first, gender gaps in opportunity, such as lower educational enrollment rates for girls than for boys, harm diversification by constraining the potential pool of human capital available in an economy. Second, gender gaps in the labor market impede the development of new ideas by decreasing the efficiency of the labor force. Our empirical estimates support these hypotheses, providing evidence that gender-friendly policies could help countries diversify their economies.

The anatomy of retention in the Federal Government : Why do productive workers stay?

description: People are an organization’s most important asset. Employees substantially influence organizational performance, and worker turnover imposes considerable costs on organizations. We examine both the intent to retire and the intent to leave the agency (retention), apart from retirement, but we focus on retention. While private organizations can employ a complex mix of high-powered incentives to retain workers, public organizations often lack comparable incentives, making retention more challenging. Fortunately, public employees frequently possess stronger intrinsic motives—a finding that implies public organizations can rely on other means to retain workers. Results indicate discretionary authority and goal and role clarity may be especially useful tools upon which the federal government can rely to retain employees. We also find that the intent to leave rises with each level of education, perhaps indicating more educated employees have better opportunities elsewhere. We also find substantial “lemming” effects: when others in the agency seek to leave, the average individual agency employee is also more likely to report the intention to leave. Findings also point to the need for additional research on public sector turnover and retention.

Isoniazid (INH), an efficient and commonly used chemotherapy for both prevention and therapy of TB, is the current front-line treatment regimen. Although the exact target of action for M. Tuberculosis is tuberculosis. This study, along with an outline of the related literature, discusses recent developments made in the quest for InhA inhibitors up to now. A background of the biology of TB is given in the first section of this article which is followed by drugs resistance, InhA аnd іtѕ іnhіbіtors. The rise in the number of InhA inhibitors is beneficial for the production of new multidrug-resistant drugs for Mycobacterium tuberculosis. The goal now is to strengthen the pharmacological activity of these inhibitors and convert them into drug development.

description: We consider an asymptotically free vectorial gauge theory, with gauge group $G$ and $N_f$ fermions in a representation $R$ of $G$, having an infrared fixed point of the renormalization group. We calculate scheme-independent series expansions for the anomalous dimensions of higher-spin bilinear fermion operators at this infrared fixed point up to $O(Δ_f^3)$, where $Δ_f$ is an $N_f$-dependent expansion variable. Our general results are evaluated for several special cases, including the case $G={\rm SU}(N_c)$ with $R$ equal to the fundamental and adjoint representations.

description: We investigate the possibility that the Universe is reionized by the decay products of heavy particles. In particular we study under which circumstances this decay may produce a significant reionization at high redshift ($z \simeq 20$), as requested by the WMAP result.Extra sources of reionization at high redshifts increase the recombination rate. As a result, the number density of decaying particles required to produce a high level of ionization at $z \simeq 10-20$ is significantly higher ($\simeq 300$ times) than previously estimated. Moreover, the ionization produced by decay particles implies a high optical depth even if the maximum level of ionization ever produced is of the order of $10^{-2}$. In order to match the cosmic microwave background polarization power spectrum, other significant sources of reionization are needed at low redshift. Decaying particles producing a ionization fraction $x \simeq 0.5$ at $z \simeq 20$ would imply an optical depth much too high to fit the cosmic microwave background spectra at $l \ge 30$. For decay times $t_{dec} < 2 \times 10^{16} {\rm s}$, recent cosmic microwave background and large scale structure data limits the primordial abundance of the decaying particles to $Ω_x \le 21 \times 10^{-9} (1+z)^3$ at 95 % C.L., and favors long decay times. The data do not favor this reionization model versus the instantaneous reionization one. We also find that the decay of these heavy particles significantly heats up the medium, bringing the expected $y$ distortion to unobservable levels.

Parallel and Perpendicular Lamellae on Corrugated Surfaces

name: Andelman, David
Publisher: name: arXiv
Year: 2003
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We consider the relative stability of parallel and perpendicular lamellar layers on corrugated surfaces. The model can be applied to smectic phases of liquid crystals, to lamellar phases of short-chain amphiphiles and to lamellar phases of long-chain block copolymers. The corrugated surface is modelled by having a single $q$-mode lateral corrugation of a certain height. The lamellae deform close to the surface as a result of chemical interaction with it. The competition between the energetic cost of elastic deformations and the gain in surface energy determines whether parallel or perpendicular lamellar orientation (with respect to the surface) is preferred. Our main results are summarized in two phase diagrams, each exhibiting a transition line from the parallel to perpendicular orientations. The phase diagrams depend on the three system parameters: the lamellar natural periodicity, and the periodicity and amplitude of surface corrugations. For a fixed lamellar periodicity (or polymer chain length), the parallel orientation is preferred as the amplitude of surface corrugation decreases and/or its periodicity increases. Namely, for surfaces having small corrugations centered at long wavelengths. For a fixed corrugation periodicity, the parallel orientation is preferred for small corrugation amplitude and/or large lamellae periodicity. Our results are in agreement with recent experimental results carried out on thin block copolymer films of PS-PMMA (polystyrene-polymethylmethacrylate) in the lamellar phase, and in contact with several corrugated surfaces.

title: Gender Issues and Social Change: Evaluating Programme Impact in Rural Bangladesh
Creators: name: van Swinderen, Anne Marie
Publisher: name: The Open University
Year: 1996

description: In rural Bangladesh many Non-Governmental Organisations run development programmes through which they aim to alleviate poverty. Host of these organisations have set themselves economic, social, gender and other objectives. Despite the fact that these organisations in principle do not prioritize economic,objectives over the other objectives, it has been noted that economic aspects are more emphasized in evaluations than social ones. In this study a range of social development dimensions have been explored. A variety of indicators were developed to investigate how these development dimensions could be evaluated at the village level and in particular how programme impact could be evaluated. Many of the indicators were derived from people's opinions about certain social issues, most of which concern women's lives. Social data are often of a qualitative nature, which makes evaluation difficult, especially when two sets of data are to be compared. In this study the qualitative data obtained for several indicators were transformed into quantitative data. The research showed that many of the indicators chosen, and the way in which they were used, indeed have potential for social and gender evaluation. Ways in which they might be modified and further developed as an evaluative tool are suggested.
title: Nucleic acid integrity and synthesis in relation to seed vigour in sugar beet
Creators: name: Redfearn, Melanie
Publisher: name: The Open University
Year: 1996

description: This research has been directed to understanding the nature of vigour in seeds of sugar beet and to methods for predicting germination success. The ratio of extractable RNA to DNA correlated significantly (p<0.05) with vigour assessments made using a range of germination tests and field trials when the seedlots fi-om several cultivars were analysed together. However, comparisons of selected seedlots all of similar high quality produced few significant correlations between the laboratory assessments (RNA/DNA ratios and germination test measurements) and field performance.

Triploid cultivars yielded more extractable nucleic acids than diploid cultivars although overall the ratio of RNA to DNA was not affected by ploidy level. The amount of extractable RNA and DNA and the RNA/DNA ratio increased with fruit size although within the smaller size range used commercially, fruit size did not affect the RNA/DNA ratio.

A primed advancement treatment which improved field performance and produced faster germination at 9°C, had higher RNA/DNA ratios in comparison with thiram-steeped seedlots. The root tips from the embryos of advanced seeds also showed a higher percentage of nuclei with 4°C DNA contents compared to those of untreated seeds but without cell division occurring indicating that the advancement treatment facilitated RNA synthesis and DNA replication. The RNA/DNA ratios of artificially aged seeds did not reflect the loss in germination seen in the standard germination test. Artificially ageing seeds produced a slightly lower percentage of root tip nuclei with a 4°C DNA content although this decrease was more pronounced for advanced then artificially aged seeds.

At 24°C, seedlots differing in vigour showed equal capabilities for the repair of single strandDNA breaks following y-irradiation, but had different capabilities for repair at 9°C. Limited repair occurred in the seedlot with poor performance under sub-optimal germination conditions, suggesting that the ability to repair DNA under stress could be a useful indicator of overall seed vigour.

description: The pi N --> KY and KY --> KY reactions are studied using a dynamical coupled-channel model of meson-baryon interactions at energies where the baryon resonances are strongly excited. The channels included are: pi N, K Λ, and KΣ. The resonances considered are: N^* [S_{11}(1650), P_{11}(1710), P_{13}(1720),D_{13}(1700)]; Δ^* [S_{31}(1900), P_{31}(1910), P_{33}(1920)]; Λ^* [S_{01}(1670), P_{01}(1810)] Σ^* [P_{11}(1660), D_{13}(1670)]; and K^*(892). The basic non-resonant πN --> KY and KY --> KY transition potentials are derived from effective Lagrangians using a unitary transformation method. The dynamical coupled-channel equations are simplified by parametrizing the pi N -->pi N amplitudes in terms of empirical pi N partial-wave amplitudes and a phenomenological off-shell function. Two models have been constructed. Model A is built by fixing all coupling constants and resonance parameters using SU(3) symmetry, the Particle Data Group values, and results from a constituent quark model. Model B is obtained by allowing most of the parameters to vary around the values of model A in fitting the data. Good fits to the available data for pi^- p to K^0 Λ, K^0 Σ^0 have been achieved. The investigated kinematics region in the center-of-mass frame goes from threshold to 2.5 GeV. The constructed models can be imbedded into associated dynamical coupled-channel studies of kaon photo- and electro-production reactions.

description: By use of the slave-boson mean-field approach, we have studied the electron-doped t-t'-t''-J model in the antiferromagnetic (AF) state. It is found that at low doping the Fermi surface (FS) pockets appear around $(\pmπ,0)$ and $(0,\pmπ)$, and upon increasing doping the other ones will form around $(\pm{π\over 2},\pm{π\over 2})$. The evolution of the FS with doping as well as the calculated spectral weight are consistent with the experimental results.

description: People are an organization’s most important asset. Employees substantially influence organizational performance, and worker turnover imposes considerable costs on organizations. We examine both the intent to retire and the intent to leave the agency (retention), apart from retirement, but we focus on retention. While private organizations can employ a complex mix of high-powered incentives to retain workers, public organizations often lack comparable incentives, making retention more challenging. Fortunately, public employees frequently possess stronger intrinsic motives—a finding that implies public organizations can rely on other means to retain workers. Results indicate discretionary authority and goal and role clarity may be especially useful tools upon which the federal government can rely to retain employees. We also find that the intent to leave rises with each level of education, perhaps indicating more educated employees have better opportunities elsewhere. We also find substantial “lemming” effects: when others in the agency seek to leave, the average individual agency employee is also more likely to report the intention to leave. Findings also point to the need for additional research on public sector turnover and retention.
