description: Supported by several recent investigations, the empirical pricing kernel (EPK) puzzle might be considered a stylized fact. Based on an economic model with state dependent preferences for the financial investors, we want to emphasize a microeconomic view that succeeds in explaining the puzzle. We retain the expected utility framework in a one period model and illustrate the case when the state is defined with respect to a reference point. We further investigate how the model relates the shape of the EPK to the economic conditions.

description: We develop a new statistical method for estimating functional connectivity between neurophysiological signals represented by a multivariate time series. We use partial coherence as the measure of functional connectivity. Partial coherence identifies the frequency bands that drive the direct linear association between any pair of channels. To estimate partial coherence, one would first need an estimate of the spectral density matrix of the multivariate time series. Parametric estimators of the spectral density matrix provide good frequency resolution but could be sensitive when the parametric model is misspecified. Smoothing-based nonparametric estimators are robust to model misspecification and are consistent but may have poor frequency resolution. In this work, we develop the generalized shrinkage estimator, which is a weighted average of a parametric estimator and a nonparametric estimator. The optimal weights are frequency-specific and derived under the quadratic risk criterion so that the estimator, either the parametric estimator or the nonparametric estimator, that performs better at a particular frequency receives heavier weight. We validate the proposed estimator in a simulation study and apply it on electroencephalogram recordings from a visual-motor experiment.

description: This thesis explores advanced joining techniques for primary metallic aircraft structures, focusing on hybrid and bonded joints to enhance airframe durability and longevity. It challenges traditional fastened joints, which have mechanical performance issues. The study examines joints representing thin and thick structural assemblies.

Experimental and numerical analyses, alongside various NDI techniques, show that while both joint types perform well, hybrid joints mitigate undetectable defects, allowing for early damage detection and preventing catastrophic failure. They extend the average aircraft's lifespan by up to fourfold, significantly reducing repair costs and wastage, and improving aircraft availability. These findings pave the way for certification procedures for hybrid joints in primary aircraft structures.

description: Background: Online news reports are increasingly becoming a source for event based early warning systems that detect natural disasters. Harnessing the massive volume of information available from multilingual newswire presents as many challenges as opportunities due to the patterns of reporting complex spatiotemporal events. Results: In this article we study the problem of utilising correlated event reports across languages. We track the evolution of 16 disease outbreaks using 5 temporal aberration detection algorithms on text-mined events classified according to disease and outbreak country. Using ProMED reports as a silver standard, comparative analysis of news data for 13 languages over a 129 day trial period showed improved sensitivity, F1 and timeliness across most models using cross-lingual events. We report a detailed case study analysis for Cholera in Angola 2010 which highlights the challenges faced in correlating news events with the silver standard. Conclusions: The results show that automated health surveillance using multilingual text mining has the potential to turn low value news into high value alerts if informed choices are used to govern the selection of models and data sources. An implementation of the C2 alerting algorithm using multilingual news is available at the BioCaster portal http://born.nii.ac.jp/?page=globalroundup.

description: Ausgehend von den vier Stäben mit keulenkopfförmigen Knäufen, die im »Königsgrab« von Spoleto (prov. Perugia) in Umbrien gefunden wurden, begibt sich der Verfasser auf die Spurensuche nach Objekten in etruskischen und italischen Bestattungen, die als Zepter zu deuten sind. Diese von einfachen Waffen abzugrenzen, ist nicht immer einfach, da die Grenzen fließend sind und auch eine profane Keule zur Ritualwaffe und zur Herrscherinsigne werden kann. Über die einzelnen Fundkontexte, bildlichen Darstellungen und Vergleiche mit anderen Kulturen (Assyrien, Ägypten) gelingt es aber, bestimmte Zepterformen archäologisch zu belegen. Der Beitrag bietet somit eine Übersicht und Klassifizierung der 46 J. Weidig · Früheisenzeitliche etruskische und italische Zepter nachweisbaren Zepterformen, die auch weibliche Insignien berücksichtigt. Zudem wird der Frage nachgegangen, welche realen Machtbefugnisse mit dem Zepter vom 9. zum 6. Jahrhundert v. Chr. in Italien verbunden waren. Dabei werden verschiedene reale und symbolische Funktionsebenen sichtbar, die auf politische, militärische, richterliche und rituell-religiöse Komponenten schließen lassen, die von dem Herrscher ausgeübt wurden.

description: At present, the power grid has tight control over its dispatchable generation capacity but a very coarse control on the demand. Energy consumers are shielded from making price-aware decisions, which degrades the efficiency of the market. This state of affairs tends to favor fossil fuel generation over renewable sources. Because of the technological difficulties of storing electric energy, the quest for mechanisms that would make the demand for electricity controllable on a day-to-day basis is gaining prominence. The goal of this paper is to provide one such mechanisms, which we call Digital Direct Load Scheduling (DDLS). DDLS is a direct load control mechanism in which we unbundle individual requests for energy and digitize them so that they can be automatically scheduled in a cellular architecture. Specifically, rather than storing energy or interrupting the job of appliances, we choose to hold requests for energy in queues and optimize the service time of individual appliances belonging to a broad class which we refer to as "deferrable loads". The function of each neighborhood scheduler is to optimize the time at which these appliances start to function. This process is intended to shape the aggregate load profile of the neighborhood so as to optimize an objective function which incorporates the spot price of energy, and also allows distributed energy resources to supply part of the generation dynamically.

description: The current survey of 83 e-therapy websites with marriage and family therapists examined what consumers seeking online therapy or therapy over the phone might find on the Internet. The study explored how e-therapy websites characterize their services and comply with the ethical guidelines of the American Association for Marriage and Family Therapy. Furthermore, differences in compliance with ethical guidelines among the three types of the websites (individual practice websites, group practice websites, and independent contractor websites) were analyzed. Results indicated that a majority of the websites lack information regarding several major areas (e.g., crisis resources, terms of service, procedures to treatment of minors, procedures to provision of therapy across borders). In support of previous findings, compliance to ethical guidelines was low and uneven. The websites focused mostly on positive aspects of e-therapy and in some cases, used suggestive or misleading language. When the three groups were compared, the independent contractor websites demonstrated statistically significantly higher compliance than the other two groups. This study points out several disturbing patterns and calls for clear e-therapy guidelines, which are currently lacking.
IC 4663: The first unambiguous [WN] Wolf-Rayet central star of a planetary nebula

description: We report on the serendipitous discovery of the first central star of a planetary nebula (PN) that mimics the helium- and nitrogen-rich WN sequence of massive Wolf-Rayet (WR) stars. The central star of IC 4663 (PN G346.2-08.2) is dominated by broad He II and N V emission lines which correspond to a [WN3] spectral type. Unlike previous [WN] candidates, the surrounding nebula is unambiguously a PN. At an assumed distance of 3.5 kpc, corresponding to a stellar luminosity of 4000 Lsun, the V=16.9 mag central star remains 4-6 mag fainter than the average luminosity of massive WN3 stars even out to an improbable d=8 kpc. The nebula is typical of PNe with an elliptical morphology, a newly discovered Asymptotic Giant Branch (AGB) halo, a relatively low expansion velocity (v_exp=30 km/s) and a highly ionised spectrum with an approximately Solar chemical abundance pattern. The [WN3] star is hot enough to show Ne VII emission (T_*=140+/-20 kK) and exhibits a fast wind (v_infty=1900 km/s), which at d=3.5 kpc would yield a clumped mass loss rate of Mdot = 1.8 x 10^-8 Msun/yr with a small stellar radius (R_*=0.11 Rsun). Its atmosphere consists of helium (95%), hydrogen (<2%), nitrogen (0.8%), neon (0.2%) and oxygen (0.05%) by mass. Such an unusual helium-dominated composition cannot be produced by any extant scenario used to explain the H-deficiency of post-AGB stars. The O(He) central stars share a similar composition and the discovery of IC 4663 provides the first evidence for a second He-rich/H-deficient post-AGB evolutionary sequence [WN]->O(He). This suggests there is an alternative mechanism responsible for producing the majority of H-deficient post-AGB stars that may possibly be expanded to include other He-rich/H-deficient stars such as R Coronae Borealis stars and AM Canum Venaticorum stars. The origin of the unusual composition of [WN] and O(He) central stars remains unexplained.

description: Understanding the causes and effects of spatial aggregation is one of the most fundamental problems in ecology. Aggregation is an emergent phenomenon arising from the interactions between the individuals of the population, able to sense only -at most- local densities of their cohorts. Thus, taking into account the individual-level interactions and fluctuations is essential to reach a correct description of the population. Classic deterministic equations are suitable to describe some aspects of the population, but leave out features related to the stochasticity inherent to the discreteness of the individuals. Stochastic equations for the population do account for these fluctuation-generated effects by means of demographic noise terms but, owing to their complexity, they can be difficult (or, at times, impossible) to deal with. Even when they can be written in a simple form, they are still difficult to numerically integrate due to the presence of the "square-root" intrinsic noise. In this paper, we discuss a simple way to add the effect of demographic stochasticity to three classic, deterministic ecological examples where aggregation plays an important role. We study the resulting equations using a recently-introduced integration scheme especially devised to integrate numerically stochastic equations with demographic noise. Aimed at scrutinizing the ability of these stochastic examples to show aggregation, we find that the three systems not only show patchy configurations, but also undergo a phase transition belonging to the directed percolation universality class.

description: Postpartum Depression (PPD) has gained well-deserved traction in healthcare policy discourse as a public health concern. Although one in seven American women are believed to experience PPD, mental illness stigma induces feelings of shame and guilt, reduces treatment-seeking behaviors, and ultimately contributes to a low PPD diagnosis rate. Risk of experiencing PPD is associated with various contextual factors, yet little is known about the association between stigma and PPD risk factors. A multiple-segment factorial vignette was used with 1,871 respondents to examine the impact of maternal age, depression history, infant temperament, and diagnosis on attitudes toward PPD. In addition, the impact of an educational video on PPD symptom recognition and stigmatizing attitudes was examined with a subsample of 1,178 respondents. Results demonstrated that a mother’s age, history of depression, and her infant’s temperament impacted respondents’ attribution of her symptoms to baby blues or PPD, and also influenced stigmatizing attitudes toward her PPD experience. Results also revealed that the educational video had a positive effect on symptom recognition and reduced stigmatizing views. Implications of these findings are discussed.

description: By means of Diffusion Monte Carlo calculations, we obtained the complete phase diagrams of H$_2$ adsorbed on the outer surface of isolated armchair carbon nanotubes of radii ranging from 3.42 to 10.85 Å. We only considered density ranges corresponding to the filling of the first adsorption layer in these curved structures. In all cases, the zero-temperature ground state was found to be an incommensurate solid, except in the widest tube, in which the structure with lowest energy is an analogous of the $\sqrt{3} \times \sqrt{3}$ phase found in planar substrates. Those incommensurate solids result form the arrangement of the hydrogen molecules in circumferences whose plane is perpendicular to the main axis of the carbon nanotube. For each tube, there is only one of such phases stable in the density range considered, except in the case of the (5,5) and (6,6) tubes, in which two of these incommensurate solids are separated by novel first order phase transitions.

description: Vector Gravimetry with inertial navigation systems has been successfully performed in semi-kinematic mode for several years. With advances in the kinematic use of GPS, also kinematic vector gravimetry has come within reach. The thesis deals with the problems of reducing the effects of INS sensor errors, determining the kinematic acceleration by means of GPS observations, and modelling the gravity vector in a state space setting. The requirements on INS and GPS observations are investigated in a covariance analysis. Different INS mechanizations, strapdown, platform, and rotating sensor unit, are compared. It is shown that only the last two are suited for vector gravimetry. Subject to the principal limitations of a simulation study, the quantitative results show that current INS and GPS hardware should allow the determination of deflections of the vertical with an accuracy of 1 arcsec. The determination of gravity anomalies with an accuracy of 10 ?ms-2, however, imposes very stringent requirements on the determination of the kinematic acceleration with GPS, which may possibly be met by high data rates and extensive filtering.
THE GRADIENT OF PAIN AS A UNIVERSAL PERSPECTIVE: AN ACADEMIC ANALYSIS
Creators: name: Ioffe, Yuriy
Publisher: name: Zenodo

description: Introduction

The nature of sensation, motivation, and consciousness remains a central problem in philosophy, psychology, and cognitive science. This study proposes a model in which all forms of affective experience can be reduced to the dynamics of a pain gradient—a continuous spectrum where the distinction between suffering and pleasure becomes topological rather than discrete. The working hypothesis is that all subjectivity derives from the system’s capacity for affective response, and that this response is always coded as pain—even when it appears in a positive form (Craig, 2003; Damasio, 1999).

description: The Standard Model (SM) prediction of the top quark forward backward asymmetry is shown to be slightly enhanced by a correction factor of 1.05 due to electroweak Sudakov (EWS) logarithms of the form (α/sin^2 θ_W)^n log^{m< 2n} (s/M_{W,Z}^2). The EWS effect on the dijet and t \bar{t} invariant mass spectra is significant, reducing the SM prediction by ~20, 10 % respectively for the highest invariant masses measured at the LHC, and changing the shape of the high-mass tail of the spectrum. These corrections significantly affect measurements of the top quark invariant mass spectrum and the search for an excess of events related to the top quark forward-backward asymmetry.

description: Sub-100 nm polymeric spherical plano-convex nano-lens arrays are fabricated using short electron beam exposures to selectively modify the ultrathin (< 30 nm) polymer films, followed by their intensified self-organized dewetting under an aqueous-organic mixture. A short exposure to e-beam locally modifies the polymer chains to effectively change the viscosity of the film in small domains, thus bringing in the dynamical dewetting contrast in the film that produces aligned and ordered dewetted nanostructures. Both negative and positive e-beam tone polymers are thus used to produce array of nano-lenses. The intensified self-organized dewetting under a water-organic solvent mixture overcomes the limitations on surface tension and dewetting force and thus facilitates the formation of sub-100 nm diameter polymer nanolenses of tunable curvature. By varying the extent of e-beam exposure, various configurations from isolated to connected nano-lens arrays can be fabricated.

description: The present chapter investigates the relative order of attributive adjectives in German. Based on corpus data, our results corroborate previous findings that semantics is the most important factor in accounting for adjective order. Going beyond previous studies, we also consider coordinated structures (such as mit [[großem, verwildertem] Garten] ‘with (a) large, overgrown garden’), where both adjectives are of equal rank. While adjective order in embedded structures (mit [ schwierigem [ familiärem Hintergrund ]] ‘with (a) difficult domestic background’) can be predicted rather accurately on semantic grounds, we show that predictions can also be made for coordinated structures, albeit with lower accuracy. Using regression analysis, we examine how semantic factors interact with a number of other explanatory variables.

description: Background: Micro-blogging services such as Twitter offer the potential to crowdsource epidemics in real-time. However, Twitter posts ('tweets') are often ambiguous and reactive to media trends. In order to ground user messages in epidemic response we focused on tracking reports of self-protective behaviour such as avoiding public gatherings or increased sanitation as the basis for further risk analysis. Results: We created guidelines for tagging self protective behaviour based on Jones and Salathé (2009)'s behaviour response survey. Applying the guidelines to a corpus of 5283 Twitter messages related to influenza like illness showed a high level of inter-annotator agreement (kappa 0.86). We employed supervised learning using unigrams, bigrams and regular expressions as features with two supervised classifiers (SVM and Naive Bayes) to classify tweets into 4 self-reported protective behaviour categories plus a self-reported diagnosis. In addition to classification performance we report moderately strong Spearman's Rho correlation by comparing classifier output against WHO/NREVSS laboratory data for A(H1N1) in the USA during the 2009-2010 influenza season. Conclusions: The study adds to evidence supporting a high degree of correlation between pre-diagnostic social media signals and diagnostic influenza case data, pointing the way towards low cost sensor networks. We believe that the signals we have modelled may be applicable to a wide range of diseases.

Recent observations indicate that these ratios can be variable with time. The possible causes of variation in line ratios are limited: changes in the radiation field or changes in density, and changes in mass-loss or geometry. In this paper, we investigate the ability of changes in the radiation field to induce variability in the ratio R=f/i. To isolate the radiative effect, we use a heuristic model of temperature and radius changes in variable stars in the B and O range with low-density, steady-state winds. We model the changes in emissivity of X-ray emitting gas close to the star due to differences in level-pumping from available UV photons at the location of the gas. We find that under these conditions, variability in R is dominated by the stellar temperature. Although the relative amplitude of variability is roughly comparable for most lines at most temperatures, detectable variations are limited to a few lines for each spectral type. We predict that variable values in R due to stellar variability must follow predictable trends found in our simulations. Our model uses radial pulsations as a mode of stellar variability that maximizes the amplitude of variation in R. This model is robust enough to show which ions will provide the best opportunity for observing variability in the f/i ratio at different stellar temperatures, and the correlation of that variability with other observable parameters. In real systems, the effects would be more complex than in our model, with differences in phase and suppressed amplitude in the presence of non-radial pulsations. This suggests that changes in R across many lines concurrently are not likely to be produced by a variable radiation field.

Secular stagnation or stagnation policy? Steindl after Summers
Creators: name: Hein, Eckhard

description: The debate on secular stagnation suffers from vagueness and several shortcomings, which affect its economic policy implications. In this work we provide an alternative view on the advanced economies’ tendencies to stagnation, based on Josef Steindl’s contributions. Steindl’s pioneering 1952 book in particular is not prone to several problems that affect the current debate on secular stagnation. It does not rely on the dubious notion of an equilibrium real interest rate as the equilibrating force of saving and investment at full employment levels. Rather, it is based on the notion that modern capitalist economies face aggregate demand constraints, and that saving adjusts to investment through income growth and changes in capacity utilisation in the long run. Steindl’s treatment allows for potential growth to become endogenous to actual demand, and it seriously considers the role of institutions and power relationships for long-run growth. In illustrating Steindl’s contributions on this topic, the article presents an original model synthetizing the main points in particular concerning long run growth and stagnation.

Testing directional forecast value in the presence of serial correlation

description: Common approaches to test for the economic value of directional forecasts are based on the classical Chi-square test for independence, Fisher’s exact test or the Pesaran and Timmerman (1992) test for market timing. These tests are asymptotically valid for serially independent observations. Yet, in the presence of serial correlation they are markedly oversized as confirmed in a simulation study. We summarize serial correlation robust test procedures and propose a bootstrap approach. By means of a Monte Carlo study we illustrate the relative merits of the latter. Two empirical applications demonstrate the relevance to account for serial correlation in economic time series when testing for the value of directional forecasts.
A Fuzzy Classification Framework to Identify Equivalent Atoms in Complex Materials and Molecules

description: The nature of an atom in a bonded structure -- such as in molecules, in nanoparticles or solids, at surfaces or interfaces -- depends on its local atomic environment. In atomic-scale modeling and simulation, identifying groups of atoms with equivalent environments is a frequent task, to gain an understanding of the material function, to interpret experimental results or to simply restrict demanding first-principles calculations. While routine, this task can often be challenging for complex molecules or non-ideal materials with breaks of symmetries or long-range order. To automatize this task, we here present a general machine-learning framework to identify groups of (nearly) equivalent atoms. The initial classification rests on the representation of the local atomic environment through a high-dimensional smooth overlap of atomic positions (SOAP) vector. Recognizing that not least thermal vibrations may lead to deviations from ideal positions, we then achieve a fuzzy classification by mean-shift clustering within a low-dimensional embedded representation of the SOAP points as obtained through multidimensional scaling. The performance of this classification framework is demonstrated for simple aromatic molecules and crystalline Pd surface examples.

Macroeconomic and Technological Dynamics: a Structuralist-Keynesian Cumulative Growth Model
Creators: name: Guarini, Giulio
Publisher: name: PSL Quarterly Review

Subjects: subject: cumulative growth, labour productivity, Kaldor law
subject: O41, O33, O47

description: In the Structuralist-Keynesian approach, economic growth is a cumulative causation process driven by a continuous interaction between macroeconomic and technological dynamics, involving several structural variables. In this context, labour productivity is both an input of the growth process, influencing macroeconomic dynamics, and a consequence of growth, because technological progress is endogenous and depends on macroeconomic dynamics. The aim of this paper is to build a Structuralist-Keynesian cumulative growth model driven by the dynamic interaction between the demand regime and the productivity regime. The model specifies the role of labour productivity and unit labour costs in the macroeconomic and technological dynamics. The results show that the effect of unit labour cost dynamics on economic growth depends on the degree of product market competition, innovation, and the distributional effects on aggregate demand. Finally, the main relationships of the model are empirically investigated for the European countries in the period 1992-2012, using both System GMM and Difference GMM dynamic panel models.

Survey of Smoking Attitudes and Behaviour, 1981
Creators: name: Censuses, Office Of Population
Publisher: name: UK Data Service
Year: 1987

description: The Joint Committee on Research into Smoking, set up by the Social Science Research Council and the Medical Research Council, recommended in their Report in 1978 that a new study should be undertaken of attitudes towards smoking, and, in particular, of the relationship between such attitudes and smoking behaviour. The recommendation stressed that the new study should go beyond the conventional range of attitude surveys and probe smokers' motivation in some detail. The Department of Health and Social Security accepted this recommendation and commissioned the Social Survey Division of the Office of Population Censuses and Surveys to undertake such a survey. The main aim of this survey was to explore the attitudes and beliefs that determine the intention to smoke or not to smoke and how such intentions might determine subsequent behaviour.

description: Objective: To identify the asymmetry of fatty infiltration and cross-sectional areas (CSAs) of individual paravertebral muscles in persons with hemiplegic presentation post-stroke. Methods: We retrospectively reviewed 26 patients with unilateral hemiplegia who underwent lumbar magnetic resonance imaging post-stroke. CSAs and functional CSAs (FCSAs) of individual paraspinal muscles (multifidus, erector spinae, quadratus lumborum, and psoas major) at the mid-disc level were bilaterally measured from L1-L2 to L5-S1 on T2-weighted lumbar axial images. The FCSA-to-total CSA ratio of each paraspinal muscle was also calculated. These parameters were compared between the more-affected and less-affected sides, and between the less chronic and chronic phases. Results: FCSA (p = .049) and FCSA-to-total CSA ratio (p = .044) were significantly smaller at the L5-S1 multifidus on the more-affected side than on the less-affected side in the chronic phase. Other muscles showed no meaningful changes. The erector spinae on the more-affected side and the multifidus on the less-affected side significantly increased in size in the chronic phase compared with the less chronic phase. Conclusions: Persons with hemiplegic presentation may have unilateral atrophy and fatty infiltration of the multifidus on the more-affected side during the chronic phase. The comparison between the less chronic and chronic phases suggested that the recovery pattern of the trunk muscles could differ between sides in unilateral hemiplegia: increased size of the multifidus, a tonic stabilizer, on the less-affected side and of the erector spinae, a phasic muscle, on the more-affected side. This finding could be applied to trunk rehabilitation strategies for persons post-stroke.
Inflation or output targeting? Monetary policy appropriateness in south Africa

description: The design and implementation of monetary policy in South Africa has been based on the idea of a trade-off between inflation and output growth. However, in the empirical literature there is no consensus on the existence of a Phillips curve in present times. This study aims to estimate the Hybrid New Keynesian Phillips Curve model with a view to determine whether a Phillips curve exists for South Africa and to ascertain whether backward-looking or forward-looking components drive inflation dynamics. Employing both OLS and GMM estimation techniques and using various measures of the demand-side variables, we do not find evidence of a Phillips curve in South Africa. These findings are robust across estimation methodologies as well as different measurements of inflation expectations and data frequency. Our findings therefore support the argument that monetary policy ought to aim at targeting growth rather than inflation. While our findings indicate that economic agents in South Africa are both rational and adaptive in predicting inflation, the results clearly indicate the dominance of forward looking variables over the backward looking ones in driving inflation.
