description: While most textbooks in managerial economics now give some coverage to business learning, and this is to be welcomed, their coverage of business learning is limited to a consideration of increases in productivity or cost reductions. Supply-side bias exists. The coverage of leading texts is reviewed. It is found that no attention is given to the underlying sources of business learning nor to phases of such learning. The ‘start-up’ phase, for example, is not specifically mentioned. Connections with productivity progress are not well explored and the possibility that business learning may depend on the duration of learning as well as the cumulative output of a business is not considered. The duration of learning is treated as an important variable in learning models developed in this paper. These models make it easier to distinguish between effects of learning on productivity or costs, and scale economies. It is also argued that more attention should be given to learning patterns of existing businesses for a change of their technique or major alteration of their product. Models, some of which involve a degree of ‘lock-in’ to existing techniques, are outlined for this purpose. In addition, other neglected microeconomic aspects of learning are considered. Lack of attention in managerial economics to learning about markets is seen as a grave shortcoming. More attention ought to be given to the alternative strategies available to a business for learning and aspects of motivation and activation for learning should not be neglected. It is then observed that the theory of optimal transfer pricing in multi-divisional firms makes no allowance for learning by the divisions. If learning is important, this is a further shortcoming.

description: Calibrating photometric redshift errors in weak lensing surveys with external data is extremely challenging. We show that both Gaussian and outlier photo-z parameters can be self-calibrated from the data alone. This comes at no cost for the neutrino masses, curvature and dark energy equation of state $w_0$, but with a 65% degradation when both $w_0$ and $w_a$ are varied. We perform a realistic forecast for the Vera Rubin Observatory (VRO) Legacy Survey of Space and Time (LSST) 3x2 analysis, combining cosmic shear, projected galaxy clustering and galaxy - galaxy lensing. We confirm the importance of marginalizing over photo-z outliers. We examine a subset of internal cross-correlations, dubbed "null correlations", which are usually ignored in 3x2 analyses. Despite contributing only $\sim$ 10% of the total signal-to-noise, these null correlations improve the constraints on photo-z parameters by up to an order of magnitude. Using the same galaxy sample as sources and lenses dramatically improves the photo-z uncertainties too. Together, these methods add robustness to any claim of detected new Physics, and reduce the statistical errors on cosmology by 15% and 10% respectively. Finally, including CMB lensing from an experiment like Simons Observatory or CMB-S4 improves the cosmological and photo-z posterior constraints by about 10%, and further improves the robustness to systematics. To give intuition on the Fisher forecasts, we examine in detail several toy models that explain the origin of the photo-z self-calibration. Our Fisher code LaSSI (Large-Scale Structure Information), which includes the effect of Gaussian and outlier photo-z, shear multiplicative bias, linear galaxy bias, and extensions to $Λ$CDM, is publicly available at https://github.com/EmmanuelSchaan/LaSSI .

description: Reviews linear break-even analysis as typically outlined in textbooks on managerial economics. It is claimed that a major shortcoming of these expositions is their failure to demonstrate in what circumstances linear break-even analysis is relevant for a business and in what circumstances it is inapplicable. This article helps rectify this situation. It points out that such analysis can not be applied to perfectly competitive firms. However, in special circumstances, it might apply to a purely competitive firm. It is highly relevant for businesses operating in oligopolistic conditions where the kinked demand curve applies. Furthermore, it is applicable if imperfectly competitive firms follow fixed price rules. On the other hand, if imperfectly competitive firms, such as monopolists, adopt flexible pricing (for example, prices to clear whatever quantity of product they have supplied to the market) the linearity assumption involved in this type of break-even analysis will, as a rule, be violated. This is so because the firm’s total revenue will be a non-linear function of the quantity of the product supplied by the firm to the market. Nevertheless, because fixed price behaviour by businesses may be common, as well as constant average variable costs of production over a considerable range of output, linear break-even analyses has a considerable range of application to business
Trans-sonic propeller stage

description: We follow the approach used by Davies and Pringle (1981) and discuss the trans-sonic substage of the propeller regime. This substage is intermediate between the supersonic and subsonic propeller substages. In the trans-sonic regime an envelope around a magnetosphere of a neutron star passes through a kind of a reorganization process. The envelope in this regime consists of two parts. In the bottom one turbulent motions are subsonic. Then at some distance $r_\mathrm{s}$ the turbulent velocity becomes equal to the sound velocity. During this substage the boundary $r_\mathrm{s}$ propagates outwards till it reaches the outer boundary, and so the subsonic regime starts. We found that the trans-sonic substage is unstable, so the transition between supersonic and subsonic substages proceeds on the dynamical time scale. For realistic parameters this time is in the range from weeks to years.

description: Outlines changes in Australian economic policies that have occurred in recent decades in response to growing economic globalisation. It considers microeconomic reforms in Australia and changes to its industry policy (including important changes in national competition policy) its financial reforms (exchange rate and banking reforms), its liberalisation of international trade and of foreign investment, both inward and outward. Furthermore, particular consideration is given to Australia’s policies and its lobbying in relation to The World Trade Organisation (WTO), economic regionalism, and bilateralism. These policies provide further insights into the way that Australia has responded to growing economic globalisation.

description: Teen drug abuse is a burgeoning international problem; 8.7 million U.S. teenagers had used illegal drugs in just the prior month, according to NIDA families should be educated on the subject because, in fact, such behaviors can have several sources: social; behavioral and psychological causes. Initiating use of alcohol and drugs as a teen nearly always leads to addiction, delayed cognitive development[,] and myriad serious health problems. This manuscript focuses on the epidemiology, risk factors, and pharmacological/behavioral therapies for adolescent substance use disorder (ASUD), highlighting both detoxification options as well as Medication-Assisted Therapy (MAT) with several drug classes in addition to including Behavioral Therapies such Cognitive-Behavioral-Therapy CBT along Motivational Interviewing MI. The value of family-focused therapies and early intervention is emphasized, especially for adolescents who have other mental health problems. Although effective treatments are available, addressing stigma, enhancing access to care and promoting family engagement remains problematic.

description: Many problems at the forefront of theoretical astrophysics require the treatment of magnetized fluids in dynamical, strongly curved spacetimes. Such problems include the origin of gamma-ray bursts, magnetic braking of differential rotation in nascent neutron stars arising from stellar core collapse or binary neutron star merger, the formation of jets and magnetized disks around newborn black holes, etc. To model these phenomena, all of which involve both general relativity (GR) and magnetohydrodynamics (MHD), we have developed a GRMHD code capable of evolving MHD fluids in dynamical spacetimes. Our code solves the Einstein-Maxwell-MHD system of coupled equations in axisymmetry and in full 3+1 dimensions. We evolve the metric by integrating the BSSN equations, and use a conservative, shock-capturing scheme to evolve the MHD equations. Our code gives accurate results in standard MHD code-test problems, including magnetized shocks and magnetized Bondi flow. To test our code's ability to evolve the MHD equations in a dynamical spacetime, we study the perturbations of a homogeneous, magnetized fluid excited by a gravitational plane wave, and we find good agreement between the analytic and numerical solutions.

description: Both China and Australia have participated in the process of growing economic globalisation in recent decades. This paper compares trends in the openness of China’s and Australia’s economy in terms of international trade and foreign direct investment, and then examines global trends in international tourism. This dimension of growing globalisation indicates an accelerating trend in the second half of the 20th century. The article shows how China was able to take advantage of this trend as a consequence of its economic reforms and opening up to the outside world. A mini-case study of the expansion of China’s tourism industry and its evolving policy framework is provided. Australia also has obtained significant growth in its tourism industry in recent decades, particularly its international tourism sector. The reasons for this are outlined and some comparisons are made between China’s and Australia’s tourism industry. A discussion of the observed trends follows. It is argued that while growth in inbound tourism has fostered economic growth, this has been obtained at the price of increased economic vulnerability of this industry. It is speculated that while growing globalisation of industry may promote economic growth, it also often has the unwelcome effect of raising the economic vulnerability of industry
Quality Prediction on Deep Generative Images

description: In recent years, deep neural networks have been utilized in a wide variety of applications including image generation. In particular, generative adversarial networks (GANs) are able to produce highly realistic pictures as part of tasks such as image compression. As with standard compression, it is desirable to be able to automatically assess the perceptual quality of generative images to monitor and control the encode process. However, existing image quality algorithms are ineffective on GAN generated content, especially on textured regions and at high compressions. Here we propose a new naturalness-based image quality predictor for generative images. Our new GAN picture quality predictor is built using a multi-stage parallel boosting system based on structural similarity features and measurements of statistical similarity. To enable model development and testing, we also constructed a subjective GAN image quality database containing (distorted) GAN images and collected human opinions of them. Our experimental results indicate that our proposed GAN IQA model delivers superior quality predictions on the generative image datasets, as well as on traditional image quality datasets.

Diagnosis. Length: 6.50–8.00 mm; width: 5.50–6.50 mm. Form elongate oval, dorsum only weakly convex and glabrous, sides of pronotum and elytra explanate. Dorsal side (Fig. 33a, b) dull yellow to brownish yellow, sometimes elytra with weak suggestion of paler longitudinal stripes, one adjacent to suture, one discal, one sublateral; pronotum with very weakly suggested browner M-shaped mark medially; underside and mouthparts, especially metasternum, slightly darker brownish-yellow, mesan-and metepisterna and epimera paler yellow than metaventrite; tarsal claws and apices of mandibles darker brown (from Booth 1997). Genitalia not studied.
Distribution. India: Uttarakhand (listed as Uttar Pradesh in Booth 1997); Bhutan; China.
Seasonal occurrence. Collected during June–September (label data).
Notes. It is externally similar to Calvia albida Bielawski, but the elytra of the former have a weak mottled pattern of small either slightly paler or slightly darker spots against the lime green (live specimens) or pale yellow (dead specimens) background colour and the prosternal process is convex, entirely lacking carinae (Booth 1997). It is also similar to C. flaveola, but the male genitalia are distinctive.

description: We devise a Monte-Carlo based, optimized filter match method to extract the thermal Sunyaev-Zel'dovich (SZ) signature of a catalog of 116 low-redshift X-ray clusters from the first year data release of the Wilkinson Microwave Anisotropy Probe (WMAP). We detect an over-all amplitude for the SZ signal at the ~ 8-sigma level, yielding a combined constraint of f_{gas}h = 0.08 +/- 0.01 (ran) +/- 0.01 (sys) on the gas mass fraction of the Intra-Cluster Medium. We also compile X-ray estimated gas fractions from the literature for our sample, and find that they are consistent with the SZ estimates at the 2-sigma level, while both show an increasing trend with X-ray temperature. Nevertheless, our SZ estimated gas fraction is 30-40% smaller than the concordance LCDM cosmic average. We also express our observations in terms of the SZ flux-temperature relation, and compare it with other observations, as well as numerical studies. Based on its spectral and spatial signature, we can also extract the microwave point source signal of the clusters at the 3-sigma level, which puts the average microwave luminosity (at ~ 41 GHz) of bright cluster members (M_K < -21) at (2.4 +/- 0.8) x 10^{27} h^{-2} erg/s/Hz. Furthermore, we can constrain the average dark matter halo concentration parameter to c_{vir}=3.4+0.6-0.9, for clusters with T_x > 5 kev. Our work serves as an example for how correlation of SZ surveys with cluster surveys in other frequencies can significantly increase our physical understanding of the intra-cluster medium.

description: We present three explicit formulas for the number of electronic configurations in an atom, i.e. the number of ways to distribute $Q$ electrons in $N$ subshells of respective degeneracies $g_1$, $g_2$, ..., $g_N$. The new expressions are obtained using the generating-function formalism. The first one contains sums involving multinomial coefficients. The second one relies on the idea of gathering subshells having the same degeneracy. A third one also collects subshells with the same degeneracy and leads to the definition of a two-variable generating function, allowing the derivation of recursion relations. Concerning the distribution of population on $N$ distinct subshells of a given degeneracy $g$, analytical expressions for the first moments of this distribution are given. The general case of subshells with any degeneracy is analyzed through the computation of cumulants. A fairly simple expression for the cumulants at any order is provided, as well as the cumulant generating function. Using Gram-Charlier expansion, simple approximations of the analyzed distribution in terms of a normal distribution multiplied by a sum of Hermite polynomials are given. The Edgeworth expansion has also been tested. Its accuracy is equivalent to the Gram-Charlier accuracy when few terms are kept, but it is much more rapidly divergent when the truncation order increases. While this analysis is illustrated by examples in atomic supershells it also applies to more general combinatorial problems such as fermion distributions.

description: Behavioral changes are the earliest signs of a mental disorder, but arguably, the dynamics of brain function gets affected even earlier. Subsequently, spatio-temporal structure of disorder-specific dynamics is crucial for early diagnosis and understanding the disorder mechanism. A common way of learning discriminatory features relies on training a classifier and evaluating feature importance. Classical classifiers, based on handcrafted features are quite powerful, but suffer the curse of dimensionality when applied to large input dimensions of spatio-temporal data. Deep learning algorithms could handle the problem and a model introspection could highlight discriminatory spatio-temporal regions but need way more samples to train. In this paper we present a novel self supervised training schema which reinforces whole sequence mutual information local to context (whole MILC). We pre-train the whole MILC model on unlabeled and unrelated healthy control data. We test our model on three different disorders (i) Schizophrenia (ii) Autism and (iii) Alzheimers and four different studies. Our algorithm outperforms existing self-supervised pre-training methods and provides competitive classification results to classical machine learning algorithms. Importantly, whole MILC enables attribution of subject diagnosis to specific spatio-temporal regions in the fMRI signal.

description: Preliminary evidence suggests that women, including female researchers, are disproportionately affected by the COVID-19 pandemic in terms of unequal distribution of childcare, elderly care and other kinds of domestic and emotional labor. Sudden lockdowns and abrupt shifts in daily routines have disproportionate consequences on their productivity, which is reflected by a sudden drop in research output in biomedical research, consequently affecting the number of female authors of scientific publications. We investigate the proportion of male and female researchers who published scientific papers during the COVID-19 pandemic, using bibliometric data from biomedical preprint servers and selected Springer-Nature journals. Our findings document a decrease in the number of publications by female authors in biomedical field during the global pandemic. This effect is particularly pronounced for papers related to COVID-19, indicating that women are producing fewer publications related to COVID-19 research. This sudden increase in the gender gap is persistent across the ten countries with the highest number of researchers. These results should be used to inform the scientific community of the worrying trend in COVID-19 research and the disproportionate effect that the pandemic has on female academics.

In this paper we use the same sample to study evolution of the FUV luminosity density. We detect evolution consistent with a (1+z)^{2.5+/-0.7} rise to z~1 and (1+z)^{0.5+/-0.4} for z>1. The luminosity density from the most UV-luminous galaxies (UVLG) is undergoing dramatic evolution (x30) between 025%) of the total FUV luminosity density at z<1. We measure dust attenuation and star formation rates of our sample galaxies and determine the star formation rate density as a function of redshift, both uncorrected and corrected for dust. We find good agreement with other measures of the SFR density in the rest ultraviolet and Halpha given the still significant uncertainties in the attenuation correction.

description: We consider a gravitational wave oscillating in an initially homogeneous, magnetized fluid. The fluid is perfectly conducting and isentropic, and the magnetic field is initially uniform. We find analytic solutions for the case in which the gravitational wave is linear and unaffected by the background fluid and field. Our solutions show how gravitational waves can excite three magnetohydrodynamic (MHD) modes in the fluid: Alfven waves, and both fast and slow magnetosonic waves. Our analytic solutions are particularly useful for testing numerical codes designed to treat general relativistic MHD in dynamical spacetimes, as we demonstrate in a companion paper.

description: Classification of the non-equilibrium quantum many-body dynamics is a challenging problem in condensed matter physics and statistical mechanics. In this work, we study the basic question that whether a (1+1) dimensional conformal field theory (CFT) is stable or not under a periodic driving with $N$ non-commuting Hamiltonians. Previous works showed that a Floquet (or periodically driven) CFT driven by certain $SL_2$ deformed Hamiltonians exhibit both non-heating (stable) and heating (unstable) phases. In this work, we show that the phase diagram depends on the types of driving Hamiltonians. In general, the heating phase is generic, but the non-heating phase may be absent in the phase diagram. For the existence of the non-heating phases, we give sufficient and necessary conditions for $N=2$, and sufficient conditions for $N>2$. These conditions are composed of $N$ layers of data, with each layer determined by the types of driving Hamiltonians. Our results also apply to the single quantum quench problem with $N=1$.

description: We study the microscopic structure and the stationary propagation velocity of (1+1)-dimensional solid-on-solid interfaces in an Ising lattice-gas model, which are driven far from equilibrium by an applied force, such as a magnetic field or a difference in (electro)chemical potential. We use an analytic nonlinear-response approximation [P.A. Rikvold and M. Kolesik, J. Stat. Phys. 100, 377 (2000)] together with kinetic Monte Carlo simulations. Here we consider interfaces that move under Arrhenius dynamics, which include a microscopic energy barrier between the allowed Ising/lattice-gas states. Two different dynamics are studied: the standard one-step dynamic (OSD) [H.C. Kang and W. Weinberg, J. Chem. Phys. 90, 2824 (1992)] and the two-step transition-dynamics approximation (TDA) [T. Ala-Nissila, J. Kjoll, and S.C. Ying, Phys. Rev. B 46, 846 (1992)]. In the OSD the effects of the applied force and the interaction energies in the model factorize in the transition rates (a soft dynamic), while in the TDA such factorization is not possible (a hard dynamic). In full agreement with previous general theoretical results we find that the local interface width under the TDA increases dramatically with the applied force. In contrast, the interface structure with the OSD is only weakly influenced by the force, in qualitative agreement with the theoretical expectations. Results are also obtained for the force-dependence and anisotropy of the interface velocity, which also show differences in good agreement with the theoretical expectations for the differences between soft and hard dynamics. Our results confirm that different stochastic interface dynamics that all obey detailed balance and the same conservation laws nevertheless can lead to radically different interface responses to an applied force.

title: On the Impact of the Degree of Fluorination on the ORR Limiting Processes within Iron Based Catalysts: A Model Study on Symmetrical Films of Barium Ferrate
Creators: name: Wollstadt, Stephan
name: Clemens, Oliver
Publisher: name: MDPI
Year: 2024

description: In this study, symmetrical films of BaFeO₂.₆₇, BaFeO₂.₃₃F₀.₃₃ and BaFeO₂F were synthesized and the oxygen uptake and conduction was investigated by high temperature impedance spectroscopy under an oxygen atmosphere. The data were analyzed on the basis of an impedance model designed for highly porous mixed ionic electronic conducting (MIEC) electrodes. Variable temperature X-ray diffraction experiments were utilized to estimate the stability window of the oxyfluoride compounds, which yielded a degradation temperature for BaFeO₂.₃₃F₀.₃₃ of 590 °C and a decomposition temperature for BaFeO₂F of 710 °C. The impedance study revealed a significant change of the catalytic behavior in dependency of the fluorine content. BaFeO₂.₆₇ revealed a bulk-diffusion limited process, while BaFeO₂.₃₃F₀.₃₃ appeared to exhibit a fast bulk diffusion and a utilization region δ larger than the electrode thickness L (8 μm). In contrast, BaFeO₂F showed very area specific resistances due to the lack of oxygen vacancies. The activation energy for the uptake and conduction process of oxygen was found to be 0.07/0.29 eV (temperature range-dependent), 0.33 eV and 0.67 eV for BaFeO₂.₆₇, BaFeO₂.₃₃F₀.₃₃ and BaFeO₂F, respectively.
The symmetric branes of the H4 WZW model

description: We review the solution of the boundary CFTs that describe the symmetric branes in the Nappi-Witten gravitational wave, namely D2 and S1 branes. The D2 branes are the twisted branes of the model while the S1 branes are the Cardy branes. We present in both cases the bulk-boundary couplings and the boundary three-point couplings and discuss the relation with branes in AdS3 and in S3. We also discuss the analogy between the open string couplings in the H4 model and the couplings for magnetized and intersecting branes.

description: The objective of this thesis is the evaluation of government policy. The first two chapters are focused on policies that affect separated families; Child Maintenance, an important source of income for separated parents, and the Lone Parent Obligation reform. Chapter 2 examines the effect of receiving child maintenance on youth behavioural and social outcomes, using new methods to assess the extent to which results are driven by selection on unobservable characteristics. The findings provide compelling estimates that, among boys, child maintenance receipt is associated with significantly fewer conduct problems and better pro-social skills. Chapter 3 evaluates the Lone Parent Obligation reform which imposed work search requirements for lone mothers with a youngest child aged 5 or 6. The findings suggest that the reform was successful in increasing maternal employment, an effect size of 8 percentage points. This was accompanied by an increase in the proportion of lone mothers who were searching for work by 9 percentage points. The results are similar across two datasets and are robust to several sensitivity checks, which add credibility to the estimates. Finally, Chapter 4 focuses on the COVID-19 pandemic and mental health in the UK. It aims to isolate the effect of being in a government imposed lockdown from the threat of the virus. The results reveal that lockdown plays a large role in explaining mental health declines, with national case and death rates also found to be important. These effects are heterogeneous across the population, with younger adults, women, and lone mothers particularly vulnerable to the adverse effects of lockdown.
Emergent geometry, thermal CFT and surface/state correspondence

description: We study a conjectured correspondence between any codimension two convex surface and a quantum state (SS-duality for short). By generalizing thermofield double formalism to continuum version of the multi-scale entanglement renormalization ansatz (cMERA) and using the SS-duality, we show that thermal geometries naturally emerge as a result of hidden quantum entanglement between boundary CFTs. We therefore propose a general framework to emerge the thermal geometry from CFT at finite temperature. As an example, the case of $2d$ CFT is considered. We calculate its information metric and show that it is either BTZ black hole or thermal AdS as expected.

Sacred daemons : the perception and treatment of intellectually disabled children in British Columbia, 1870-1930
Creators: name: Clarke, Nicholas James
Publisher: name: University of British Columbia
Year: 2009

description: By examining the treatment of intellectually disabled children in British Columbia between 1870 and 1930, this paper suggests that the commonly held histriographical assumption that western children experienced "dramatic change in economic and sentimental valuation" during the late nineteenth and early twentieth centuries requires some careful qualification. For while many parents undoubtedly invested their intellectually disabled children with the sentimental value that society increasingly projected onto 'normal' children, the same cannot be said of the majority of medical and educational professionals. Indeed, rather than "sacralize" children with intellectual disabilities, government officials and medical and educational professionals 'daemonised' them.
Universality of eigenvector delocalization and the nature of the SIS phase transition in multiplex networks

description: Universal spectral properties of multiplex networks allow us to assess the nature of the transition between disease-free and endemic phases in the SIS epidemic spreading model. In a multiplex network, depending on a coupling parameter, $p$, the inverse participation ratio ($IPR$) of the leading eigenvector of the adjacency matrix can be in two different structural regimes: (i) layer-localized and (ii) delocalized. Here we formalize the structural transition point, $p^*$, between these two regimes, showing that there are universal properties regarding both the layer size $n$ and the layer configurations. Namely, we show that $IPR \sim n^{-δ}$, with $δ\approx 1$, and revealed an approximately linear relationship between $p^*$ and the difference between the layers' average degrees. Furthermore, we showed that this multiplex structural transition is intrinsically connected with the nature of the SIS phase transition, allowing us to both understand and quantify the phenomenon. As these results are related to the universal properties of the leading eigenvector, we expect that our findings might be relevant to other dynamical processes in complex networks.

description: Similarity of competitors has been proposed to facilitate coexistence of species because it slows down competitive exclusion, thus making it easier for equalizing mechanisms to maintain diverse communities. On the other hand, previous studies suggest that chaotic ecosystems can have a higher biodiversity. Here, we link these two previously unrelated findings, by analysing the dynamics of food web models. We show that near-neutrality of competition of prey, in the presence of predators, increases the chance of developing chaotic dynamics. Moreover, we confirm that chaotic dynamics correlate with a higher biodiversity.
