Intersections of the arts and art therapies in the humanization of care in hospitals: Experiences from the music therapy service of the University Hospital Fundación Santa Fe de Bogotá, Colombia

Humanization of care is becoming an increasingly important aspect in providing high-quality health services and the arts are more and more implemented to support and foster humanization and person-centered care efforts. Musical experiences are one of the most frequently encountered art forms in medical settings. Music therapy as a healthcare profession has a decades-long tradition in hospitals, both in inpatient and outpatient areas. However, while studies regarding the effectiveness of music therapy are on the forefront of clinical research, little attention has been paid to the profession's inherent opportunities to assist the hospitals' strategies in terms of humanization of care. Yet, the musical experiences in music therapy are especially versatile in supporting healthcare users from a holistic perspective, contributing to a more compassionate, personalized, and humanized environment. In this article, the basic pillars of humanized and person-centered care will be outlined, followed by examples of seven intersections in which the music therapy service of the University Hospital Fundación Santa Fe de Bogotá aligns with its Humanized and Compassionate Care Model. The aim of this article is to stimulate the discussion on music therapy not only as a profession that provides safe and effective treatment, but also as a therapeutic art experience that can add value for hospitals on their path toward a more humanized care culture.
Psychological burden predicts new-onset diabetes in men: A longitudinal observational study in the Fukushima Health Management Survey after the Great East Japan earthquake

Background The burden of psychological distress and post-traumatic stress disorder (PTSD) has been suggested as a factor in developing type 2 diabetes mellitus. However, longitudinal features in psychological distress- and PTSD-related new-onset diabetes mellitus have not been thoroughly evaluated. Methods The association between probable depression and probable PTSD and the risk of developing new-onset diabetes mellitus was evaluated in a 7-year prospective cohort of evacuees of the Great East Japan Earthquake in 2011. Probable depression was defined as a Kessler 6 scale (K6) ≥ 13 and probable PTSD as a PTSD Checklist—Stressor-Specific Version (PCL-S) ≥ 44. Results The log-rank test for the Kaplan–Meier curve for new-onset diabetes mellitus was significant between K6 ≥ 13 vs. < 13 and PCL-S ≥ 44 vs. < 44 in men but not in women. In men, both K6 ≥ 13 and PCL-S ≥ 44 remained significant in the Cox proportional hazards model after multivariate adjustment for established risk factors and disaster-related factors, including evacuation, change in work situation, sleep dissatisfaction, and education. Conclusion The post-disaster psychological burden of probable depression and probable PTSD was related to new-onset diabetes in men but not in women. In post-disaster circumstances, prevention strategies for new-onset diabetes might consider sex differences in terms of psychological burden.
f -Dominance of Gravity

A Lagrangian theory is formulated describing the intrinsic mixing of the graviton with a massive ${2}^{+}$ $f$ meson which interacts universally with hadrons through the stress tensor. The theory is developed as an analog of the well-known $\ensuremath{\rho}\ensuremath{-}\ensuremath{\gamma}$ model of hadron electrodynamics, and in particular a field-current identity is exhibited which equates the massive ${2}^{+}$ meson with the hadronic energy-momentum tensor. An Einstein-type Lagrangian is used for both spin-2 particles, and general covariance is preserved throughout. The nonlinear coupling of the hadrons to the $f$ meson leads, within the framework of nonpolynomial field theories, to a universal cutoff for strong-interaction physics.
Seeing and doing: exploring the use of journalist videos and simulations to increase news literacy awareness among high school students

ABSTRACT In this study, we test the potential of a simulation for encouraging situated, peer-based encounters for news literacy learning. High school students responded to news literacy awareness and news appreciation measures before, immediately after, and two weeks after taking part in a breaking news simulation. Before the simulation, an intervention group was shown a supplementary video featuring a journalist explaining news skills and standards. Findings show that overall the simulation did not work beyond increasing teenagers’ own perceived understanding of the concept of news literacy. However, when paired with the simulation, those who saw the journalist video reported more understanding of the value of news sourcing and appreciation for the work of journalists. This research informs the pedagogy of news literacy by showing the ineffectiveness of simulations to teach concepts to teenagers but the potential benefits of having journalists deliver them in short video messages.

Construction of a complex‐valued fractional Brownian motion of order N

In this paper, a Brownian motion of order n (n≳2) is defined by a probabilistic approach different from Hochberg’s and Mandelbrot’s. This process is constructed from sums of independent R+1/n‐valued random variables (rv) (where R+1/n={z∈C; zn∈R+}). Many properties of the real standard Brownian motion are generalized at order n, but in the case n≳2, it is interesting to describe the Brownian motion of order n on the σ algebra ⊗[B(R+1/n)] R+ [where B(R+1/n) is the σ algebra generated by sets of type A(0,h)={z∈C; zn∈[0;hn[},(heR+*)]. This σ algebra is totally different from ⊗[B(R)] R+. Thus this study shows the fractal nature of the Brownian motion of order n, and given invariance scale (self‐similarity) properties. Then, a stochastic integral and an Ito–Taylor lemma at order n are given to allow the representation of the solution of the heat equation of order n by a probabilistic average. All these results can be obtained via nonstandard analysis methods (infinitesimal time discretization). Finally, one rem.
Effectiveness of Pseudomonas aeruginosa type VI secretion system relies on toxin potency and type IV pili-dependent interaction

The type VI secretion system (T6SS) is an antibacterial weapon that is used by numerous Gram-negative bacteria to gain competitive advantage by injecting toxins into adjacent prey cells. Predicting the outcome of a T6SS-dependent competition is not only reliant on presence-absence of the system but instead involves a multiplicity of factors. Pseudomonas aeruginosa possesses 3 distinct T6SSs and a set of more than 20 toxic effectors with diverse functions including disruption of cell wall integrity, degradation of nucleic acids or metabolic impairment. We generated a comprehensive collection of mutants with various degrees of T6SS activity and/or sensitivity to each individual T6SS toxin. By imaging whole mixed bacterial macrocolonies, we then investigated how these P. aeruginosa strains gain a competitive edge in multiple attacker/prey combinations. We observed that the potency of single T6SS toxin varies significantly from one another as measured by monitoring the community structure, with some toxins acting better in synergy or requiring a higher payload. Remarkably the degree of intermixing between preys and attackers is also key to the competition outcome and is driven by the frequency of contact as well as the ability of the prey to move away from the attacker using type IV pili-dependent twitching motility. Finally, we implemented a computational model to better understand how changes in T6SS firing behaviours or cell-cell contacts lead to population level competitive advantages, thus providing conceptual insight applicable to all types of contact-based competition.
Nigral-specific increase in ser31 tyrosine hydroxylase phosphorylation offsets dopamine loss and forestalls hypokinesia onset during progressive nigrostriatal neuron loss

Mechanisms that augment dopamine (DA) signaling to compensate for tyrosine hydroxylase (TH) loss and delay motor impairment in Parkinson’s disease remain unidentified. The rat nigrostriatal pathway was unilaterally-lesioned by 6-OHDA to determine whether differences in DA content, TH protein, TH phosphorylation, or D1 receptor expression in striatum or substantia nigra (SN) aligned with onset of hypokinesia at two time points. At 7 days, DA and TH loss in striatum exceeded 95%, whereas DA was unaffected in SN, despite ∼60% TH loss. At 28 days, hypokinesia was established. At both time points, ser31 TH phosphorylation increased only in SN, corresponding to less DA versus TH loss. ser40 TH phosphorylation was unaffected in striatum or SN. By day 28, D1 receptor expression increased only in lesioned SN. These results indicate that increased ser31 TH phosphorylation and D1 receptor in the SN, not striatum, augment DA signaling against TH loss to mitigate hypokinesia. Highlights –Despite >90% TH and DA loss in striatum, open-field locomotor activity did not decrease –Early after lesion, DA and TH loss in striatum exceeded 90%. In contrast, DA loss did not occur despite 60% TH loss in substantia nigra (SN). –TH loss was progressive in the SN, with loss also spreading contralateral to lesion. –Loss of TH protein in SN preceded cell loss ipsilateral and contralateral to lesion, indicating first stages of nigrostriatal neuron loss begin with loss of TH protein loss. –TH phosphorylation at ser31 in SN was associated with less, if any, DA loss compared to TH protein loss. –TH phosphorylation at ser40 did not change in either region and at any time during TH loss, suggesting no contribution to differences in DA loss against TH loss. –Expression of the D1 receptor increased 2.5-fold in the SN late, but not early, after lesion, suggesting a post-synaptic receptor response to offset DA loss in SN. –No increases in TH phosphorylation or D1 receptor expression in striatum at any time after lesion induction, indicating that compensatory mechanisms occur only in substantia nigra, but not in striatum, to delay onset of hypokinesia.
Quantification of the diversity sampling bias resulting from rice root bacterial isolation on popular and nitrogen-free culture media, using 16S amplicon barcoding

Culturing bacteria from plant material is well known to introduce a strong bias compared to the real diversity present in the original samples. This bias is related to cultivability of bacteria, the chemical composition of media and culture conditions. The bias of recovery is often observed but was never quantified on different media using an amplicon barcoding approach comparing plant microbiota DNA extractions versus DNA extracted from serial dilutions of the same plant tissues grown on bacterial culture media. In this study, we i) quantified the culturing diversity bias using 16S amplicon barcode sequencing by comparing a culture-dependent approach (CDA) on rice roots on four popular bacterial media (Tryptone Soybean Agar-TSA-at two concentrations, 10% and 50%; a plant-based media with rice flour; Norris Glucose Nitrogen Free Medium-NGN; and Nitrogen Free -NFb) versus a culture-independent approach (CIA) assessed from DNA extracted directly on root and rhizosphere samples; ii) assessed enriched and missing taxa detected on the different media; iii) use biostatistics functional predictions to predict which metabolic profiles are enriched in the CDA and CIA. A comparative analysis of the two approaches revealed that among the 22 phyla present in the microbiota of the studied rice root samples, only five were present on the culture media approach (Proteobacteria, Firmicutes, Bacteroidetes, Actinobacteria, Verrucomicrobia). The Proteobacteria phylum was the most abundant in all cultured media samples, showing a high enrichment of gamma-Proteobacteria. The diversity of the combined culture media represented about 1/3 of the diversity of the total microbiota, and its genus diversity and frequency was documented. The functional prediction tool (PiCrust2) detected an enrichment of nitrogenase enzyme in bacterial taxa sampled from Nitrogen-free media, validating its predictive capacity. Further functional predictions also showed that the CDA missed mostly anaerobic, methylotrophic, methanotrophic and photosynthetic bacteria compared to the culture independent approach, delivering valuable insights to design ad-hoc culture media and conditions to increase cultivability of the rice-associated microbiota.
Policies without Memory for the Infinite-Armed Bernoulli Bandit under the Average-Reward Criterion

We consider a bandit problem with infinitely many Bernoulli arms whose unknown parameters are i.i. d. We present two policies that maximize the almost sure average reward over an infinite horizon. Neither policy ever returns to a previously observed arm after switching to a new one or retains information from discarded arms, and runs of failures indicate the selection of a new arm. The first policy is nonstationary and requires no information about the distribution of the Bernoulli parameter. The second is stationary and requires only partial information; its optimality is established via renewal theory. We also develop ε-optimal stationary policies that require no information about the distribution of the unknown parameter and discuss universally optimal stationary policies.
A Stastistical Analysis of Cointegration for I(2) Variables

This paper discusses inference for I(2) variables in a VAR model. The estimation procedure suggested consists of two reduced rank regressions. The asymptotic distribution of the proposed estimators of the cointegrating coefficients is mixed Gaussian, which implies that asymptotic inference can be conducted using the χ2 distribution. It is shown to what extent inference on the cointegration ranks can be conducted using the tables already prepared for the analysis of cointegration of I(1) variables. New tables are needed for the test statistics to control the size of the tests. This paper contains a multivariate test for the existence of I(2) variables. This test is illustrated using a data set consisting of U.K. and foreign prices and interest rates as well as the exchange rate.
Stellar Birthrate in the Galaxy: Constraints from X-Ray Flux-limited Surveys

The determination of the X-ray luminosity functions of few coeval stellar samples (such as open clusters and stellar associations) with the Einstein data has shown that the average level of X-ray emission from coronal source decrease with the age of the emitting stars. We show how the assumed history of the Galactic stellar birthrate (and therefore the number of young X-ray emitting stars today) influences the expected star count distributions in X-ray flux limited surveys. Assuming several different smooth stellar birthrates we have computed model-predicted log (N)-log (S), whose normalization agrees with optical star counts, and have compared them with the actual number of sources detected in the Extended Medium Sensitivity Survey
Tracking the Success of Pre-College Algebra Workshop Students in Subsequent College Mathematics Classes

Abstract In 2007 the Department of Mathematics at our institution began developing a placement process designed to identify at-risk students entering mathematics courses at the College Algebra and Calculus levels. Major changes in our placement testing process and the resulting interventions for at-risk students were put in place in Fall of 2008. At the lowest level of this placement process we seek to intervene with students who traditionally perform very poorly in university-level classes by offering a self-paced remediation course. The current work will outline the basics of this remedial program and present data confirming the efficacy of the intervention.
Structure of supersonic jets with vortex generators at the nozzle exit

The spatial structure of the flow in a supersonic underexpanded jet exhausting from a convergent nozzle with vortex generators (chevrons) at the exit is experimentally studied. Disturbances of two types are observed during interaction of a single chevron and the main jet. The stronger disturbance is caused by the presence of the wake component and by generation of two streamwise vortices. The weaker disturbance is manifested in the form of perturbations of the Mach wave type propagating in the supersonic part of the shear layer of the main jet. Interaction of the set of chevrons with the jet flow leads to transformation of the stationary jet structure and to formation of mushroom-shaped large-scale vortex structures. The experimental and numerical data are demonstrated to be in reasonable agreement.
An improved magnetic field model for Jupiter's inner magnetosphere using a microsignature of Amalthea

Observation of a particle absorption microsignature of the Jovian satellite Amalthea during the Pioneer 11 close flyby of Jupiter on December 3, 1974, has been described by McKibben et al. [1983]. The microsignature was also observed by the University of Iowa/Pioneer 11 instrument in the distribution of protons in the kinetic energy range 0.61 < Tp < 3.41 MeV but has not been previously reported. The finer time resolution and superior data quality of the latter observations provide a fresh basis for assessing the accuracy with which various published magnetic field models of Jupiter's magnetic field models describe Jupiter's magnetic field for radial distances of the order of or less than several planetary radii. The expected time of occurrence of the minimum of Amalthea's microsignature was calculated for each model and compared to the time of the observed minimum. The discrepancy between these two times was significant for each of the published models, but it could be reduced to zero by interpolating between two of the closely related models. The spherical harmonic coefficients of this combination model are tabulated. Also included is a novel method for calculating the intensity-time profile of the microsignature. In a later paper, the improved model is utilized to analyze the energetic particle measurements in Jupiter's innermost magnetosphere by the Galileo entry probe in December 1995 [Fischer et al., 1996].
Quality time with the fractious Fourier family

The Fourier family comprises a wide variety of mathematical transforms, some of them well established in the image-science community, some lesser known but deserving of more recognition. The goal of this paper is to survey the genealogy of this family and to show some possibly non-obvious applications of each member. Three central premises run through the discussion: (1) There can be no science of imaging without a scientific approach to the evaluation of image quality; (2) Image quality must be defined in terms of the information that is desired from the image and the method of extracting that information; (3) Digital images are discrete data obtained from a continuous object. These considerations will lead us to rely on rather different members of the Fourier family than the ones most often encountered in polite imaging society.
Microvariability in high-amplitude δ Scuti radially pulsating stars

Analyses of existing data of high-amplitude b Scuti stars (HADS) show that variability, at the mmag level, is a common phenomenon among them. Detailed period analyses show that, apart from the already known case of AI Vel, two other stars SX Phe and DY Peg are also pulsating with more radial and/or non-radial periods than usually believed. The phenomenon, only visible when high-quality observations are available, can be of considerable interest because of the tight constraints that this imposes on the theoretical models.
The infrared continuum of active galactic nuclei

We discuss the different physical processes contributing to the infrared continuum of active galactic nuclei (AGNs), assuming that both photoionization from the active centre and shocks ionize and heat the gas and dust contained in an ensemble of clouds surrounding the nucleus. In our model, radiation transfer of primary and secondary radiation throughout a cloud is calculated consistently with collisional processes due to the shock. We consider that the observed continuum corresponds to reprocessed radiation from both dust and gas in the clouds. Collisional processes are important in the presence of shocks. The grains are sputtered crossing the shock front. The models are constrained by sputtering as well as by the far-infrared data. The model is applied to the continuum of Seyfert galaxies from which the best estimate of the nuclear, stellar subtracted, emission is available. The results show that radiation-dominated high-velocity clouds are more numerous in Seyfert 1-1.5 whereas shock-dominated low-velocity clouds are dominant in Seyfert type 2. This result is in full agreement with the unified model for AGNs, by which high-velocity clouds, placed deeper into the central region and therefore reached by a more intense radiation, should play a more significant role in the spectra of broad-line objects. We could therefore conclude that in type 2 objects, radiation is partly suppressed by a central dusty medium with a high dust-to-gas ratio. Once the model approach is tested, a grid of models is used to provide a phenomenological analysis of the observed infrared spectral energy distribution. This empirical method is a useful tool to rapidly access the physical conditions of the AGN emitting clouds. For this, analytical forms are derived for the two processes contributing to the infrared emission: dust emission and thermal bremsstrahlung produced by the narrow-line region clouds. Their relative contribution provides a measurement of the dust-to-gas ratio.
Evidences of oxygen-mediated resistive-switching mechanism in TiN\HfO2\Pt cells

In this letter, we study the influence of the Pt top-electrode thickness and of the chamber atmosphere during cell operation on the resistive switching of TiN\HfO2\Pt cells. The oxygen permeability of the Pt electrode directly in contact with the atmosphere significantly affects the resistive switching and the resistance states of the cell. The results provide strong experimental indications that the electroforming operation leads to oxygen-vacancy formation and that the subsequent reset operation relies on the available oxygen species in the filament neighborhood. Significant implications with respect to endurance and retention assessment of resistive-switching memory devices are discussed.
