Predicting affective appraisals from facial expressions and physiology using machine learning
Authors: Israel Laura S. F. , Schönbrodt Felix D. 
Published: August 2020

AbstractThe present study explored the interrelations between a broad set of appraisal ratings and five physiological signals, including facial EMG, electrodermal activity, and heart rate variability, that were assessed in 157 participants watching 10 emotionally charged videos. A total of 134 features were extracted from the physiological data, and a benchmark comparing different kinds of machine learning algorithms was conducted to test how well the appraisal dimensions can be predicted from these features. For 13 out of 21 appraisals, a robust positiveR2was attained, indicating that the dimensions are actually related to the considered physiological channels. The highestR2(.407) was reached for the appraisal dimensionintrinsic pleasantness. Moreover, the comparison of linear and nonlinear algorithms and the inspection of the links between the appraisals and single physiological features usingaccumulated local effectsplots indicates that the relationship between physiology and appraisals is nonlinear. By constructing different importance measures for the assessed physiological channels, we showed that for the 13 predictable appraisals, the five channels explained different amounts of variance and that only a few blocks incrementally explained variance beyond the other physiological channels.
Probing the Physical Conditions and Star Formation Processes in the Galactic H II Region S305

Published: August 2020

Abstract
We present multiscale and multiwavelength observations of the Galactic H ii region S305, which is excited by massive O8.5V and O9.5V stars. Infrared images reveal an extended sphere-like shell (extension ∼7.5 pc; at T

d
= 17.5–27 K) enclosing the S305 H ii region (size ∼5.5 pc; age ∼1.7 Myr). The extended structure observed in the Herschel temperature map indicates that the molecular environment of S305 is heated by the massive O-type stars. Regularly spaced molecular condensations and dust clumps are investigated toward the edges of the infrared shell, where the polycyclic aromatic hydrocarbon (PAH) and H2 emission is also observed. The molecular line data show a signature of an expanding shell of molecular gas in S305. Giant Metrewave Radio Telescope 610 and 1280 MHz continuum maps reveal overdensities of the ionized emission distributed around two O-type stars, which are surrounded by the horseshoe envelope (extension ∼2.3 pc). A molecular gas deficient region/cavity is identified toward the center of the horseshoe envelope, which is well traced with PAH, H2, molecular, and dust emission. The edges of the infrared shell are found to be located in the front of the horseshoe envelope. All these outcomes provide the observational evidence of the feedback of O-type stars in S305. Moreover, nonthermal radio emission is detected in S305 with an average spectral index α ∼ −0.45. The variations in α, ranging from −1.1 to 1.3, are explained due to soft synchrotron emission and either optically thicker thermal emission at high frequencies or a suppression of the low-frequency emission by the Razin–Tsytovich effect.

Abstract
The Faint Intergalactic Medium Redshifted Emission Balloon (FIREBall) is a mission designed to observe faint emission from the circumgalactic medium of moderate-redshift (z ∼ 0.7) galaxies for the first time. FIREBall observes a component of galaxies that plays a key role in how galaxies form and evolve, likely contains a significant amount of baryons, and has only recently been observed at higher redshifts in the visible. Here we report on the 2018 flight of the FIREBall-2 Balloon telescope, which occurred on 2018 September 22 from Fort Sumner, New Mexico. The flight was the culmination of a complete redesign of the spectrograph from the original FIREBall fiber-fed integral field unit to a wide-field multiobject spectrograph. The flight was terminated early owing to a hole in the balloon, and our original science objectives were not achieved. The overall sensitivity of the instrument and telescope was 90,000 LU, due primarily to increased noise from stray light. We discuss the design of the FIREBall-2 spectrograph, including modifications from the original FIREBall payload, and provide an overview of the performance of all systems. We were able to successfully flight-test a new pointing control system, a UV-optimized, delta-doped, and coated electron multiplying CCD, and an aspheric grating. The FIREBall-2 team is rebuilding the payload for another flight attempt in the fall of 2021, delayed from 2020 as a result of COVID-19.
A Model-insensitive Baryon Acoustic Oscillation Feature in the 21 cm Signal from Reionization
Authors: Cain Christopher , D’Aloisio Anson , Iršič Vid , McQuinn Matthew , Trac Hy 
Published: August 2020

Abstract
We examine the impact of baryon-dark matter relative velocities on intergalactic small-scale structure and the 21 cm signal during reionization. Streaming velocities reduced clumping in the intergalactic medium on mass scales of ∼104–108
M
⊙. This effect produced a distinct baryon acoustic oscillation (BAO) feature in the 21 cm power spectrum at wavenumbers k ∼ 0.1 h/Mpc, near which forthcoming surveys will be most sensitive. In contrast to the highly uncertain impact of streaming velocities on star formation, the effect on clumping is better constrained because it is set mainly by cosmology and straightforward gas dynamics. We quantify the latter using coupled radiation-hydrodynamic simulations that capture the Jeans scale of pre-reionization gas. The clumping factor of ionized gas is reduced by 5%–10% in regions with rms streaming velocities. The suppression peaks ≈5 Myr after a region is reionized, but disappears within 200 Myr due to pressure smoothing. We model the corresponding impact on the 21 cm signal and find that the BAO feature is most likely to appear at ≈10% ionization. During this phase, the feature may appear at the 1% (5%) level at k ∼ 0.1 (0.06) h/Mpc with an amplitude that varies by a factor of <10 across a range of reionization histories. We also provide a model for the signal originating from streaming velocity’s impact on ionizing sources, which can vary by 4 orders of magnitude depending on highly uncertain source properties. We find that the clumping signal probably dominates the source one unless Population III star formation in 106–108
M
⊙ halos contributed significantly to the first 10% of reionization.
Shock and Discontinuity Formation in the Front of an Expanding Coronal Magnetic Arcade in Two-fluid Simulations
Authors: Bagwell T. E. , Ma Z. W. 
Published: August 2020

Abstract
The dynamic evolution of a magnetic arcade associated with footpoint shearing motions is investigated by an ideal two-fluid (electron–ion) code. The two-fluid numerical simulations produce conspicuous differences compared to earlier MHD simulations beyond the inner arcade region. The decoupling motion between electrons and heavier ions during the arcade expansion induces a growing charge separation and strong electric field in the front of the expanding arcade. The presence of this electric field provides an additional force, along with the magnetic and thermal pressures, that drives the growth of an outwardly expanding wave that steepens into a propagating discontinuity in the plasma and magnetic field. The propagation speed of the discontinuity eventually exceeds the local phase velocity of the MHD fast mode and becomes a perpendicular fast-like shock. There is significant heating at the shock due to adiabatic compression, with preferential heating of the ion fluid also being observed. In addition, parameter tests indicate that (1) the propagation speed of the shock before exiting the inner arcade is independent of the maximum shear speed; (2) slower shearing speeds produce weaker shocks with weaker adiabatic heating; (3) the ion-to-electron mass ratio, m

i
/m

e
, impacts the strength of the charge separation linearly but has a moderate effect on the propagation speed; and (4) the normalized value of the ion inertial length does not affect the formation and speed of the shock as a whole.
Magnetic Field Dropouts at Near-Sun Switchback Boundaries: A Superposed Epoch Analysis
Authors: Farrell W. M. , MacDowall R. J. , Gruesbeck J. R. , Bale S. D. , Kasper J. C. 
Published: August 2020

Abstract
During Parker Solar Probe’s first close encounter with the Sun in early 2018 November, a large number of impulsive rotations in the magnetic field were detected within 50 R
s; these also occurred in association with short-lived impulsive solar wind bursts in speed. These impulsive features are now called “switchback” events. We examined a set of these switchbacks where the boundary transition into and out of the switchback was abrupt, with fast B rotations and simultaneous solar wind speed changes occurring on timescales of less than ∼10 s; these thus appear as step function-like changes in the radial component of B and V. Our objective was to search for any diamagnetic effects that might occur especially if the boundaries are associated with quick changes in density (i.e., a steep spatial density gradient at the switchback boundary). We identified 25 switchback entries where the radial component of B, B
r, quickly transitioned from large negative to positive values and V
r simultaneously abruptly increased (i.e., step-up transitions) and 28 switchback exits where B
r quickly transitioned from large positive to negative values and V
r simultaneously abruptly decreased (i.e., step-down transitions). We then performed a superposed epoch analysis on each of these sets of events. We found these fast-transitioning events typically had a clear and distinct decrease in the magnetic field magnitude by 7%–8% detected exactly at the boundary. The presence of the

dropout suggests there is a diamagnetic current present at the boundary.
L’envol du panda ? Aviation civile chinoise et innovation
Authors: Maréchal Jean-Paul 
Published: August 2020

L’objet de cet article est d’analyser la stratégie chinoise de rattrapage technologique dans le domaine de l’aviation civile. Nous procéderons en cinq étapes. On débutera par un retour sur les premières décennies de l’histoire aéronautique chinoise. Puis on analysera la politique industrielle qui, à partir des années 1990, a mené à la constitution des deux champions nationaux que sont AVIC et COMAC. Dans un troisième temps on décryptera le programme phare qu’est le C919. Dans un quatrième, on étudiera la place de la production chinoise dans le marché mondial. Pour finir, on fera le point sur la réalité du « pillage » technologique chinois dans le domaine de la construction aéronautique.
Entre résilience et rupture : l’émergence d’un nouveau modèle technologique chinois ?
Authors: Zubeldia Océane 
Published: August 2020

Depuis son arrivée au pouvoir en 2013 le Président chinois Xi Jinping a placé l’innovation technologique au centre de la stratégie chinoise. Pour stimuler son développement, l’industrie du numérique est fortement sollicitée par l’appareil étatique et sert de puissant levier tant sur le marché intérieur (contrôle de la données) que sur l’influence géopolitique (« routes de la soie digitalisée » en Asie, Europe, et Afrique). Les politiques publiques et les dynamiques privées soutiennent la modernisation de l’Armée populaire de libération (APL) qui a désormais la capacité opérationnelle de bouleverser l’équilibre stratégique de l’Asie du sud-est et de faire face aux Etats-Unis. La Chine est-elle pour autant un acteur capable de ruptures technologiques ou adapte t’elle son modèle ?
The TOLERance Model for Promoting Structural Competency in Nursing
Authors: Orr Zvika , Unger Shifra 
Published: August 2020

Background:
Structural competency is the trained ability to recognize how social, political, economic, and legal structures shape diseases and symptoms. Although structural competency has become an increasingly accepted framework for training and teaching, it usually has not addressed nursing students and has not included marginalized patients as trainers.

Method:

This article analyzes a structural competency training model for nursing students that includes five components:
T
heory,
O
bservations,
L
earning from patients,
E
ngagement, and
R
esearch (the TOLERance model).

Results:
The TOLERance model increases the understanding of the interrelation between the individual clinical level and the sociopolitical structural level. It encourages nursing students to actively engage in social, political, and policy issues that affect their patients' health and to advocate for policy change.

Conclusion:

The moral and professional commitment of nurses to their patients demands that they do not ignore the structural forces that are detrimental to their patients' health. The TOLERance model provides nursing students with skills and competencies that help them to fulfill this commitment.

Lessons Learned: Raising Awareness of Civility and Incivility Using Semi-Virtual Reality Simulation
Authors: Rose Kristine A. , Jenkins Sheryl D. , Astroth Kim , Woith Wendy , Jarvill Melissa 
Published: August 2020

Background:
The purpose of our web-based, semi-virtual reality simulation was to raise baccalaureate nursing students' awareness of civility and incivility. Educators know civility in nursing is crucial to safe and effective patient care. However, nursing students have reported physiological and psychological distress after experiencing incivility. If nurse educators are unable to better promote civility, the quality of nursing education, and ultimately nursing practice, is threatened.

Method:
We implemented an innovative civility-related, semi-virtual reality, simulation with senior-level nursing students. After attending a faculty-led discussion on the importance of civility and incivility, students participated in a web-based, semi-virtual reality simulation, followed by a synchronous debriefing session.

Results:
Students reported that the intervention raised their awareness of civility and incivility.

Conclusion:

This article describes the intervention and shares the lessons learned in implementing it so nurse educators may replicate this innovative strategy to raise awareness of civility in nursing education.

Video Storytelling in the Classroom: The Role of Narrative Transportation
Authors: Moore Amy Kenefick , Miller Robin June 
Published: August 2020

Background:
Storytelling in nursing pedagogy is widely used and generally thought to be effective, but the mechanisms by which it is effective are unclear. This project explored whether watching a professional film affected students' knowledge, beliefs, or attitudes, and whether the extent of any change varied with the amount of narrative transportation (cognitive and emotional engagement in story) experienced.

Method:

Eighty-eight students watched the film
Wit
, took a knowledge pretest and posttest, and completed an instrument to measure narrative transportation. Analysis included
t
test, correlation, and regression.

Results:
Increases in pretest–posttest scores were significant, and a statistically significant, moderate, positive correlation between students' scores for narrative transportation and the amount of change in test scores. Narrative transportation explained significant variance in posttest scores and score change.

Conclusion:

Narrative transportation seems to enhance learning and might be a mechanism by which learning occurs.

Imagens de mulheres entre a pena e o pincel: representações femininas na iconografia espanhola oitocentista
Authors: André Richard Gonçalves 
Published: August 2020

O livro da historiadora Edméia Ribeiro analisa o discurso costumbrista e hispanista inerente à coleção intitulada Las Mujeres Españolas, Portuguesas y Americanas, publicada nos anos 1870 pelo editor Miguel Guijarro. A fonte congrega artigos de diversos autores, bem como cromolitografias representando as mulheres hispânicas, portuguesas e brasileiras. Entretanto, ao versarem sobre o feminino, os autores utilizam-no como pretexto para discorrer sobre elementos como política, economia, sociedade e território numa conjuntura em que o império espanhol encontrava-se em processo de desagregação em razão dos movimentos de independência encetados pelas antigas colônias americanas. A coleção, nesse sentido, cria representações da Espanha como fundamento cultural e moral do mundo hispânico, prescrevendo, também, ideais e comportamentos relacionados às mulheres.Palavras-chave: Costrumbismo. Hispanismo. Mulheres.
América Latina em perigo: imperialismo e pan-americanismo nos escritos de César Zumeta
Authors: Gouveia Regiane Cristina 
Published: August 2020

ResumoEste artigo analisa, a partir da obra El continente enfermo (1899), do venezuelano César Zumeta (1860-1955), como o debate acerca do pan-americanismo e dos imperialismos na América Latina, em fins do século XIX e início do XX, aparece nos escritos desse autor. Examina também as soluções que o escritor propôs para os problemas do continente, que caracterizou como enfermo devido à desorganização política e às disputas e hostilidades entre as repúblicas latino-americanas. Em um contexto de modernização da América Latina, imperialismos, europeu e norte-americano, e pan-americanismo, Zumeta preocupou-se em denunciar os perigos que cercavam o continente e que poderiam levar a perdas territoriais, de independência e soberania, além da perda da tradição cultural latina. Ao fazer isso, o autor contribuiu para o fortalecimento de correntes de pensamento latino-americano que buscavam resistir à influência política, econômica e moral, norte-americana e europeia. Palavras-chave: Intelectuais; América Latina; relações interamericanas.
