Enterprise pedagogy in music: an exploration of multiple pedagogies

This article investigates the nature of enterprise pedagogy in music. It presents the results of a research project that applied the practices of enterprise learning developed in the post-compulsory music curriculum in England to the teaching of the National Curriculum for music for 11–14 year olds. In doing so, the article explores the nature of enterprise learning and the nature of pedagogy, in order to consider whether enterprise pedagogy offers an effective way to teach the National Curriculum. Enterprise pedagogy was found to have a positive effect on the motivation of students and on the potential to match learning to the needs of students of different abilities. Crucially, it was found that, to be effective, not only did the teacher's practice need to be congruent with the beliefs and theories on which it rests, but that the students also needed to share in these underlying assumptions through their learning. The study has implications for the way in which teachers work with multiple pedagogies in the process of developing their pedagogical identity.

Universal dielectric response across a continuous metal-insulator transition

A wide range of disordered materials, including disordered correlated systems, show "Universal Dielectric Response" (UDR), followed by a superlinear power-law increase in their optical responses over exceptionally broad frequency regimes. While extensively used in various contexts over the years, the microscopic underpinning UDR remains controversial. Here, we investigate the optical response of the simplest model of correlated fermions, Falicov-Kimball model (FKM), across the continuous metal-insulator transition (MIT) and analyze the associated quantum criticality in detail using cluster extension of dynamical mean field theory (CDMFT). Surprisingly, we find that UDR naturally emerges in the quantum critical region associated with the continuous MIT. We tie the emergence of these novel features to a many-body orthogonality catastrophe accompanying the onset of strongly correlated electronic glassy dynamics close to the MIT, providing a microscopic realization of Jonscher's time-honored proposal as well as a rationale for similarities in optical responses between correlated electronic matter and canonical glass formers.
Experiments with Vizzy as a Coach for Elderly Exercise

Vizzy is a wheeled humanoid robot carefully designed for an enjoyable / pleasurable interaction with humans. In this paper evaluate Vizzy’s application as an exercise coach according to user’s perceived robot aesthetics, trust, confidence, and enjoyment. We describe the proposed robotic platform skills, interfaces, and interaction modes. We have deployed Vizzy in three care centers in Portugal for the promotion of exercise activities and tested its performance with 36 elderly users. Survey data collected after the interaction with the robot show a good acceptance of the robotic platform as an exercise coach. From observations and short interviews, we also extracted a set of guidelines that led to several improvements and ideas for future work.
Impact of inter-correlated initial binary parameters on double black hole and neutron star mergers

The distributions of the initial main-sequence binary parameters are one of the key ingredients in obtaining evolutionary predictions for compact binary (BH–BH/BH–NS/NS–NS) merger rates. Until now, such calculations were done under the assumption that initial binary parameter distributions were independent. For the first time, we implement empirically derived inter-correlated distributions of initial binary parameters primary mass (M1), mass ratio (q), orbital period (P), and eccentricity (e). Unexpectedly, the introduction of inter-correlated initial binary parameters leads to only a small decrease in the predicted merger rates by a factor of ≲2–3 relative to the previously used non-correlated initial distributions. The formation of compact object mergers in the isolated classical binary evolution favours initial binaries with stars of comparable masses (q ≈ 0.5–1) at intermediate orbital periods (log P (days) = 2–4). New distributions slightly shift the mass ratios towards lower values with respect to the previously used flat q distribution, which is the dominant effect decreasing the rates. New orbital periods (∼1.3 more initial systems within log P (days) = 2–4), together with new eccentricities (higher), only negligibly increase the number of progenitors of compact binary mergers. Additionally, we discuss the uncertainty of merger rate predictions associated with possible variations of the massive-star initial mass function (IMF). We argue that evolutionary calculations should be normalized to a star formation rate (SFR) that is obtained from the observed amount of UV light at wavelength 1500 Å (an SFR indicator). In this case, contrary to recent reports, the uncertainty of the IMF does not affect the rates by more than a factor of ∼2. Any change to the IMF slope for massive stars requires a change of SFR in a way that counteracts the impact of IMF variations on compact object merger rates. In contrast, we suggest that the uncertainty in cosmic SFR at low metallicity can be a significant factor at play.
A stratigraphically controlled multiproxy chronostratigraphy for the eastern Mediterranean

[1] An Accelerator Mass Spectrometry (AMS) 14C dated multiparameter event stratigraphy is developed for the Aegean Sea on the basis of highly resolved (centimeter to subcentimeter) multiproxy data collected from four late glacial to Holocene sediment cores. We quantify the degree of proportionality and synchroneity of sediment accumulation in these cores and use this framework to optimize the confidence levels in regional marine, radiocarbon-based chronostratigraphies. The applicability of the framework to published, lower-resolution records from the Aegean Sea is assessed. Next this is extended into the wider eastern Mediterranean, using new and previously published high-resolution data from the northern Levantine and Adriatic cores. We determine that the magnitude of uncertainties in the intercore comparison of AMS 14C datings based on planktonic foraminifera in the eastern Mediterranean is of the order of ±240 years (2 SE). These uncertainties are attributed to synsedimentary and postsedimentary processes that affect the materials dated. This study also offers a background age control that allows for vital refinements to radiocarbon-based chronostratigraphy in the eastern Mediterranean, with the potential for similar frameworks to be developed for any other well-studied region.
Applications of generalized likelihood ratio tests to seismic event identification. Final report, 25 May 1990-25 August 1993

A summary of the work performed under this project is provided. It contains brief descriptions of statistical methods developed and data analysis performed during the early stages of this contract to improve yield estimation. Preliminary results of a study of discriminant transportability for Eurasia are also summarized. The main body of the report, however, focuses on development of statistical methods and their applications to seismic event identification problems relevant to monitoring a CTBT or NPT. Recently developed classification and outlier detection methods are applied to the problem of seismic event identification, particularly for regional events. The methods, based on the generalized likelihood ratio (GLR), have considerable flexibility to rigorously treat a mixture of continuous and discrete features, normal or non-normal statistics, equal or unequal covariance matrices, and different distribution functions for different event types. Statistical procedures are also presented to test the validity of appropriate assumptions and, if necessary, transform the data to simplify implementation of the outlier and classification methods to ensure that the necessary assumptions hold. Methods are also presented and applied to select the optimal subset of discriminants and to treat missing data values robustly. This collection of methods provides a robust statistical framework to identify seismic more » events and to estimate classification probabilities rigorously under extremely general conditions. « less
Ultrafast outflows in radio-loud active galactic nuclei

Recent X-ray observations show absorbing winds with velocities up to mildly-relativistic values of the order of ~0.1c in a limited sample of 6 broad-line radio galaxies. They are observed as blue-shifted Fe XXV-XXVI K-shell absorption lines, similarly to the ultra-fast outflows (UFOs) reported in Seyferts and quasars. In this work we extend the search for such Fe K absorption lines to a larger sample of 26 radio-loud AGNs observed with XMM-Newton and Suzaku. The sample is drawn from the Swift BAT 58-month catalog and blazars are excluded. X-ray bright FR II radio galaxies constitute the majority of the sources. Combining the results of this analysis with those in the literature we find that UFOs are detected in >27% of the sources. However, correcting for the number of spectra with insufficient signal-to-noise, we can estimate that the incidence of UFOs is this sample of radio-loud AGNs is likely in the range f=(50+/-20)%. A photo-ionization modeling of the absorption lines with XSTAR allows to estimate the distribution of their main parameters. The observed outflow velocities are broadly distributed between v_out 10^22 cm^-2. Overall, these characteristics are consistent with the presence of complex accretion disk winds in a significant fraction of radio-loud AGNs and demonstrate that the presence of relativistic jets does not preclude the existence of winds, in accordance with several theoretical models.
Masterclass Achilles tendinopathy

Achilles tendon injury (tendinopathy) and pain occur in active individuals, when the tendon is subject to high or unusual load. Achilles tendinopathy can be resistant to treatment, and symptoms may persist despite both conservative and surgical intervention. The pathology of overuse tendinopathy is non-inflammatory, with a degenerative or failed healing tendon response. The diagnosis of Achilles tendinopathy requires excellent differential diagnosis and an understanding of the role of tendon imaging. Conservative treatment must include exercise, with a bias to eccentric contractions. Surgical treatment is effective after complete tendon rupture, but may not assist recovery from overuse tendinopathy. Further research into the clinical aspects of Achilles tendinopathy is required. r 2002 Elsevier Science Ltd. All rights reserved.
Women, not objects: testing a sensitizing web campaign against female sexual objectification to temper sexual harassment and hostile sexism

ABSTRACT We investigated the novel hypothesis that a sensitizing web campaign against media sexual objectification would lead to lower male gender-harassing conduct (i.e., number of sexist jokes sent to a chat partner), lower sexual coercion intention (via the Likelihood to Sexually Harass scale), and lower hostile sexism (via the Ambivalent Sexism Inventory). Across two experiments (Ns = 157; 159), male participants were exposed to one of three videos: (a) a web campaign against female objectification (sensitizing), (b) a nature documentary (control), or (c) a video in which women are portrayed as sexual objects (sexually objectifying). Study 1 and Study 2 together demonstrated that men exposed to the sensitizing video showed lower gender-harassing behavior, lower hostile sexism, and lower sexual coercion intention than participants in the other two conditions altogether. Moreover, the sexually objectifying vs. control video condition led to higher gender-harassing behavior. Mediation analyses demonstrated that the sensitizing video led to lower hostile sexism, which in turn was associated with both lower gender-harassing behavior and lower sexual coercion intentions. The sensitizing video led to unexpectedly higher benevolent sexism; however, benevolent sexism was not associated with higher sexual harassment. We conclude by discussing the importance and practical implications of the results.
The sunshine vitamin D: ubiquitous source, still so deficient in mother and baby duo

Background: Vitamin D is a fat-soluble vitamin, a sunshine vitamin. Vitamin D deficiency is now recognized as a pandemic. Fetus depends on mother for its need of vitamin D, thus there is growing concern for its impact on neonates. This study was designed to determine the correlation between 25-hydroxyvitamin D (vitamin D3) levels in maternal blood and in cord blood.Methods: A total 50 term pregnant women attending antenatal clinic at SVS medical college, Telangana and their neonates were included in the study. At term after taking written consent, maternal and cord blood vitamin D3 were measured, and values were correlated. Antenatal and neonatal complications were noted, and correlated with vitamin D3 levels.Results: In this study 80% of pregnant women and 88% of neonates were vitamin D3 deficient. Mean maternal blood vitamin D3 was 17.62±10.01 and cord blood vitamin D3 was 12.84±7.68. Maternal blood vitamin D3 correlated positively with cord blood vitamin D3 (r=0.951, p<0.001). Antenatal and neonatal complications were observed, but statistically significant association with vitamin D3 deficiency could not be established.Conclusions: This study has demonstrated a very high prevalence of vitamin D deficiency in apparently healthy, young, pregnant women despite abundant sunlight leading to deficiency in their neonates. To establish strong association between vitamin D3 deficiency and various antenatal and neonatal complications further studies with large subject groups are required.
On the Evolution of Trade and Sanitary and Phytosanitary Standards: The Role of Trade Agreements

Trade agreements and trade measures are policy instruments thought to favour trade by providing a degree of harmonisation among members. We analyse how the agri-food trade and the incidence of Sanitary and Phytosanitary Standards (SPSs) have evolved within countries sharing agreements. We examine, through a regression discontinuity design, whether the approval of agreements affects the evolution of trade and SPSs over time, and quantify the trade effects of SPSs. We also provide differences before and after the introduction of agreements, and among the most regulated agri-food products. Findings show that trade agreements tend to favour the increase of trade and the reduction of policy measures between members. However, regulation inequalities exist across trade agreements covering different geo-economic areas: after the approval of agreements, the existence and the importance of SPSs become relevant among developing countries, whereas the pervasiveness of SPSs becomes less stringent between developed and developing countries. Our analyses also prove that trade agreements and trade measures are trade-enhancing only at aggregate level: product-specific analyses show that cereal is the only sector that benefits from the joint influence of trade agreements and SPSs. The harmonisation of SPSs within agreements may be determinant in avoiding distortions in favour of members.
Solar Drying Kinetics of Cass Ava Slices in a Mixed Flow Dryer

Abstract Drying characteristics of cassava slices was investigated in a mixed mode natural convection solar dryer to obtain a suitable mathematical model describing the drying. The average drying chamber temperature was between 34 ±2 °C and 50 ±1.8 °C, while 10 commonly used thin layer drying models were used for drying curve modelling. Coefficient of determination (R2) and root mean square error (RMSE) were used to determine the models performances. The drying curve of cassava slices showed a reduction of moisture content with increased drying time in the solar dryer, and the variation of moisture ratio exponentially decreased with increased drying time. The Midilli and Logarithmic models showed better fit to the experimental drying data of cassava slices. As compared with other models tested, there were no significant differences (p >0.05) in the R2 values obtained for the Midilli and Logarithmic models; hence, the Logarithmic model was preferable because of the lower RMSE. The diffusion mechanism could be used to describe the drying of cassava slices that was found to be in the falling rate period. A diffusion coefficient (Deff) of 1.22 × 10-8 m2 s-1 was obtained, which was within the established standard for food products.
Modes , stability , and small-signal response of photonic crystal Fano lasers

Photonic crystal Fano lasers have recently been realised experimentally, showing useful properties such as pinned single-mode lasing and passive pulse generation. Here the fundamental properties of the modes of the Fano laser are analysed, showing how the laser functionality depends sensitively on the system configuration. Furthermore the laser stability is investigated and linked to the small-signal response, which shows additional dynamics that cannot be explained with a conventional rate equation model, including a damping of relaxation oscillations and a frequency modulation bandwidth that is only limited by the nanocavity response. © 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreement OCIS codes: (140.0140) Lasers and laser optics; (140.5960) Semiconductor lasers; (350.4238) Nanophotonics and
Aging and Situation Model Updating

The aim of this study was to investigate age differences in narrative comprehension and memory, with a focus on the updating of situation models during comprehension. While there are large effects of aging on memory for propositional textbase information, there is very little evidence that older adults have difficulty at the situation model level. Because described events are often dynamic, a comprehender must consistently update their situation model to make it consistent with the new information. The current experiments investigated whether there are any age differences associated with the ability to update a situation model along the spatial and temporal dimensions. Although updating effects were observed, they were largely not influenced by age. The relation of these findings to an understanding of older adults’ language comprehension and memory performance is discussed.
Possible result of extreme parenting: Power of helicopter parenting attitude to predict ego inflation

The concept of helicopter parenting is used to describe a parental disposition that is excessively child-oriented, intrusive and limiting to child’s autonomy. It is characterized by parents being overly concerned about child's future, making great efforts to avoid possible negative outcomes, preferring to plan and handle child’s life and even executing child’s tasks in his/her place. The objective of this study is to establish the relation between helicopter parental attitudes and ego inflation. The Perceived Helicopter Parental Attitude Scale and Ego Inflation Scale were applied to 432 people with an age group of 24-34 years. Hypotheses of the study were tested using structural equation modelling after results related to the fit values and factor loads of the scales were determined to be appropriate and adequate. The study found that 42.80 percent of the change in the inflated ego reported in young adults can be explained by a helicopter maternal attitude (R2 = .43). Helicopter paternal attitude accounted for 22.10 percent of the change in the inflated ego observed in young adults (R2 = .22). It has, thus, been demonstrated that ego inflation is triggered by helicopter parental attitudes and helicopter attitudes of mothers are more successful in creating ego inflation than those of fathers. We hope that the findings of the present study can be used in parent education and family counselling practices.
The Variational Fair Autoencoder

We investigate the problem of learning representations that are invariant to certain nuisance or sensitive factors of variation in the data while retaining as much of the remaining information as possible. Our model is based on a variational autoencoding architecture with priors that encourage independence between sensitive and latent factors of variation. Any subsequent processing, such as classification, can then be performed on this purged latent representation. To remove any remaining dependencies we incorporate an additional penalty term based on the "Maximum Mean Discrepancy" (MMD) measure. We discuss how these architectures can be efficiently trained on data and show in experiments that this method is more effective than previous work in removing unwanted sources of variation while maintaining informative latent representations.
Parametric Study of the Rossby Wave Instability in a Two-dimensional Barotropic Disk. II. Nonlinear Calculations

Vortices in protoplanetary disks have attracted attention since the discovery of lopsided structures. One of the possible mechanisms for producing vortices is the Rossby wave instability (RWI). In our previous work, we have performed detailed linear stability analyses of the RWI with various initial conditions. In this paper, we perform numerical simulations of the vortex formation by the RWI in two-dimensional barotropic disks using the Athena++ code. As initial conditions, we consider axisymmetric disks with a Gaussian surface density bump of various contrasts and half-widths. Perturbations grow as expected from the linear stability analyses in the linear and weakly nonlinear regimes. After the saturation, multiple vortices are formed in accordance with the most unstable azimuthal mode and coalesce one after another. In the end, only one quasi-stationary vortex (the RWI vortex) remains, which migrates inward. During the RWI evolution, the axisymmetric component approaches the stable configuration. We find that the axisymmetric component reaches the marginally stable state for the most unstable azimuthal mode at the saturation and for the m = 1 mode at the final vortex merger. We investigate the structure and evolution of the RWI vortices. We obtain some empirical relations between the properties of the RWI vortices and the initial conditions. Using tracer particle analyses, we find that the RWI vortex can be considered as a physical entity, like a large fluid particle. Our results provide solid theoretical ground for quantitative interpretation of the observed lopsided structures in protoplanetary disks.
