BackgroundA growing body of research highlights the experiences of moral injury among healthcare professionals during the COVID-19 pandemic. Moral injury (i.e., participating in or witnessing acts that violate one's central moral values), is associated with a host of psychological sequelae and corresponding negative psychosocial impacts. There is a lack of research examining the experiences of moral injury among those working in long-term care settings during the COVID-19 pandemic. Given the drastic impact that the COVID-19 pandemic has had on long-term care facilities in Canada, it is important to understand the experiences of moral injury among those working in long-term care settings to inform the development of effective prevention and intervention strategies.Objectives &amp; MethodThe objectives of this study were to understand the experiences and impact of moral injury among Canadian frontline long-term care workers (staff and management) during the COVID-19 pandemic. Participants (N= 32 long-term care staff and management working in Ottawa and Manitoba) completed in-depth, semi-structured qualitative interviews and clinical diagnostic assessments (Mini International Neuropsychiatric Interviews; MINI; Version 7.0.2) between March 2021-June 2021.FindingsThe core category of our qualitative grounded theory model of moral injury in long-term care exemplified four shared types of morally injurious experiences, paired with cognitive, affective, and physiological symptom domains. Seven associated main themes emerged, contributing to the experiences and impact of moral injury in long-term care: 1) Beliefs about older adults and long-term care; 2) Interpretation of morally injurious experiences; 3) Management of morally injurious experiences; 4) Long-term care pandemic impacts; 5) Personal pandemic impacts; 6) Structural impacts in long-term care; and 7) Mental health needs and supports. Clinical assessments demonstrated anxiety disorders (n= 4) and feeding and eating disorders (n= 3) were among the most frequently classified current psychiatric disorders among long-term care workers.ConclusionsThis is the first Canadian study to examine the experiences and impact of moral injury in long-term care during the COVID-19 pandemic using qualitative and clinical diagnostic methodologies. Implications and insights for screening and intervention are offered.
Constant-Beamwidth Kronecker Product Beamforming With Nonuniform Planar Arrays
Authors: Frank Ariel , Cohen Israel 
Published: May 2022

In this paper, we address the problem of constant-beamwidth beamforming using nonuniform planar arrays. We propose two techniques for designing planar beamformers that can maintain different beamwidths in the XZ and YZ planes based on constant-beamwidth linear arrays. In the first technique, we utilize Kronecker product beamforming to find the weights, thus eliminating matrix inversion. The second technique provides a closed-form solution that allows for a tradeoff between white noise gain and directivity factor. The second technique is applicable even when only a subset of the sensors is used. Since our techniques are based on linear arrays, we also consider symmetric linear arrays. We present a method that determines where sensors should be placed to maximize the directivity and increase the frequency range over which the beamwidth remains constant, with a minimal number of sensors. Simulations demonstrate the advantages of the proposed design methods compared to the state-of-the-art. Specifically, our method yields a 1000-fold faster runtime than the competing method, while improving the wideband directivity factor by over 8 dB without compromising the wideband white noise gain in the simulated scenario.
Att-TasNet: Attending to Encodings in Time-Domain Audio Speech Separation of Noisy, Reverberant Speech Mixtures
Authors: Ravenscroft William , Goetze Stefan , Hain Thomas 
Published: May 2022

Separation of speech mixtures in noisy and reverberant environments remains a challenging task for state-of-the-art speech separation systems. Time-domain audio speech separation networks (TasNets) are among the most commonly used network architectures for this task. TasNet models have demonstrated strong performance on typical speech separation baselines where speech is not contaminated with noise. When additive or convolutive noise is present, performance of speech separation degrades significantly. TasNets are typically constructed of an encoder network, a mask estimation network and a decoder network. The design of these networks puts the majority of the onus for enhancing the signal on the mask estimation network when used without any pre-processing of the input data or post processing of the separation network output data. Use of multihead attention (MHA) is proposed in this work as an additional layer in the encoder and decoder to help the separation network attend to encoded features that are relevant to the target speakers and conversely suppress noisy disturbances in the encoded features. As shown in this work, incorporating MHA mechanisms into the encoder network in particular leads to a consistent performance improvement across numerous quality and intelligibility metrics on a variety of acoustic conditions using the WHAMR corpus, a data-set of noisy reverberant speech mixtures. The use of MHA is also investigated in the decoder network where it is demonstrated that smaller performance improvements are consistently gained within specific model configurations. The best performing MHA models yield a mean 0.6 dB scale invariant signal-to-distortion (SISDR) improvement on noisy reverberant mixtures over a baseline 1D convolution encoder. A mean 1 dB SISDR improvement is observed on clean speech mixtures.

Published: May 2022

BackgroundBevacizumab (BEV) plus chemotherapy as a neoadjuvant regimen presents good efficacy in patients with locally advanced cancer. However, its role in patients with locally advanced gastric cancer (LAGC) is not clear. Thus, the study aimed to assess the efficacy and safety of neoadjuvant BEV plus chemotherapy in patients with LAGC.MethodsTwenty resectable patients with LAGC who received BEV plus docetaxel/cisplatin/capecitabine (DCC) chemotherapy for 3 cycles with 21 days as one cycle as neoadjuvant regimen were involved. Besides, their treatment response, survival profiles, and adverse events were assessed.ResultsIn total, two (10.0%), 9 (45.0%), 8 (40.0%), and 1 (5.0%) patients achieved complete remission, partial remission, stable disease, and progressive disease (PD) according to imaging evaluation, which resulted in 55.0% of objective response rate and 95.0% of disease control rate, respectively. Moreover, the number of patients with pathological response grades 1, 2, and 3 was 8 (40.0%), 8 (40.0%), and 3 (15.0%); while 1 (5.0%) patient did not receive surgery due to PD, thus the data of this patient was not assessable. Meanwhile, 18 (90.0%) patients achieved R0 resection. Regarding survival profile, the median disease-free survival or overall survival were both not reached. The 1-year, 2-, and 3-year disease-free survival rates were 88.8, 80.7, and 67.3%. Meanwhile, the 1-, 2-, and 3-year overall survival rates were 100.0%, 75.8%, and 75.8%, respectively. Additionally, the main adverse events were anemia (90.0%), alopecia (90.0%), leukopenia (70.0%), and anorexia (65.0%). Indeed, most adverse events were of grade 1 or 2 and were manageable.ConclusionNeoadjuvant BEV plus DCC chemotherapy presents a favorable pathological response and survival profile with acceptable safety in patients with LAGC.

Key Points

Hypernatremia has been studied less than hyponatremia and may serve as an important predictor of outcomes among hospitalized patients.This work addresses a key gap regarding outcomes of hypernatremia by assessing the relationship of hypernatremia to outcomes by eGFR or age groups.Hypernatremia was significantly associated with in-hospital mortality and discharge to a hospice or nursing facility.

Background
Hypernatremia is a frequently encountered electrolyte disorder in hospitalized patients. Controversies still exist over the relationship between hypernatremia and its outcomes in hospitalized patients. This study examines the relationship of hypernatremia to outcomes among hospitalized patients and the extent to which this relationship varies by kidney function and age.

Methods
We conducted an observational study to investigate the association between hypernatremia, eGFR, and age at hospital admission and in-hospital mortality, and discharge dispositions. We analyzed the data of 1.9 million patients extracted from the Cerner Health Facts databases (2000–2018). Adjusted multinomial regression models were used to estimate the relationship of hypernatremia to outcomes of hospitalized patients.

Results
Of all hospitalized patients, 3% had serum sodium (Na) >145 mEq/L at hospital admission. Incidence of in-hospital mortality was 12% and 2% in hyper- and normonatremic patients, respectively. The risk of all outcomes increased significantly for Na >155 mEq/L compared with the reference interval of Na=135–145 mEq/L. Odds ratios (95% confidence intervals) for in-hospital mortality and discharge to a hospice or nursing facility were 34.41 (30.59–38.71), 21.14 (17.53–25.5), and 12.21 (10.95–13.61), respectively (all P<0.001). In adjusted models, we found that the association between Na and disposition was modified by eGFR (P<0.001) and by age (P<0.001). Sensitivity analyses were performed using the eGFR equation without race as a covariate, and the inferences did not substantially change. In all hypernatremic groups, patients aged 76–89 and ≥90 had higher odds of in-hospital mortality compared with younger patients (all P<0.001).

Conclusions
Hypernatremia was significantly associated with in-hospital mortality and discharge to a hospice or nursing facility. The risk of in-hospital mortality and other outcomes was highest among those with Na >155 mEq/L. This work demonstrates that hypernatremia is an important factor related to discharge disposition and supports the need to study whether protocolized treatment of hypernatremia improves outcomes.

Sur une grande partie de l'Antarctique, le bilan de masse (c'est-à-dire de neige) de surface est dominé par quelques événements de précipitations extrêmes. Ces événements dépendent d'intrusions de masses d'air très humide associées à des phénomènes dénommés rivières atmosphériques en provenance de l'océan Austral. Ces rivières atmosphériques influencent fortement le climat ; pourtant, les caractéristiques, les mécanismes et les impacts associés restent mal connus en Antarctique. Nous résumons ici l'état des connaissances sur la mise en place de ces événements extrêmes et leurs impacts à la fois sur l'accumulation de neige, le réchauffement et la fonte en surface de la calotte.
Over much of Antarctica, the surface mass balance (i.e. the resultant of snow fluxes at the surface of the ice sheet) is dominated by a few extreme precipitation events. It has recently been shown that these events are linked to intrusions of highly humid air masses related with atmospheric rivers traversing the Southern Ocean. These atmospheric rivers strongly influence the climate, yet their meteorological characterization and associated impacts remain poorly understood in Antarctica. We summarize here the latest research regarding the development of these extreme events and their impacts on snow accumulation, warming, and surface melt on the Antarctic ice sheet.

Spectral Line Depth Variability in Radial Velocity Spectra
Authors: Wise Alexander , Plavchan Peter , Dumusque Xavier , Cegla Heather , Wright Duncan 
Published: May 2022

Abstract
Stellar active regions, including spots and faculae, can create radial velocity (RV) signals that interfere with the detection and mass measurements of low-mass exoplanets. In doing so, these active regions affect each spectral line differently, but the origin of these differences is not fully understood. Here we explore how spectral line variability correlated with S-index (Ca H and K emission) is related to the atomic properties of each spectral line. Next, we develop a simple analytic stellar atmosphere model that can account for the largest sources of line variability with S-index. Then, we apply this model to HARPS spectra of α Cen B to explain Fe i line depth changes in terms of a disk-averaged temperature difference between active and quiet regions on the visible hemisphere of the star. This work helps establish a physical basis for understanding how stellar activity manifests differently in each spectral line and may help future work mitigating the impact of stellar activity on exoplanet RV surveys.
Méthodes de gestion des résultats et affiliation politique des dirigeants
Authors: Arslan-Ayaydin Özgür , Thewissen James , Torsin Wouter 
Published: May 2022

Cet article cherche à savoir si l’aversion au risque des dirigeants – estimée sur la base de leur affiliation politique – explique la méthode utilisée pour gérer les résultats. Nous soutenons que, même si la gestion réelle des résultats peut avoir des conséquences à long terme sur les performances de l’entreprise, les dirigeants républicains ont tendance à préférer la gestion réelle des résultats à la gestion des résultats par les choix comptables, puisque la première entraîne des coûts liés au risque de litiges bien moindres que la seconde et est bien plus difficile à détecter. Sur la base d’un échantillon de plus de 20 000 observations annuelles d’entreprises, nous avons constaté que les entreprises dirigées par des Républicains (ayant une plus forte aversion au risque) ont tendance à gérer leurs résultats par manipulation des activités réelles, tandis que celles dirigées par des Démocrates (davantage tournés vers la prise de risques) ont tendance à favoriser la gestion des résultats par les choix comptables. Nous montrons également que la relation positive (négative) des dirigeants de penchant républicain à la gestion réelle des résultats (par les choix comptables) est plus positive (moins négative) pour les dirigeants dont la rémunération dépend davantage de la prise de risques.
Dans les marges de l’action publique
Authors: Frau Caroline , Taiclet Anne-France 
Published: May 2022

Résumé L’analyse des relais de l’action publique prolonge l’exploration des chaînes d’intermédiation de l’action publique en focalisant son attention sur des formes de délégation non instituée, informelle, sans cahier des charges, qui font intervenir, parfois malgré eux, des acteurs dont les pratiques de travail assurent la circulation de l’action publique jusqu’au « niveau de la rue ». Envisager une gamme diversifiée de façons inégalement volontaires, conscientes et appliquées de relayer l’action publique, par des professionnels dont l’activité n’est pas dédiée à ce rôle et qui l’occupent de manière plus ou moins contrainte et en marge de la définition principale de leur métier, permet d’élargir le spectre des acteurs et des situations d’intermédiation de l’action publique. Pris dans des logiques publiques, professionnelles et individuelles souvent contradictoires, ces relais, à la fois récepteurs et retransmetteurs, participent à la définition pratique de l’action publique. Leurs situations charnières donnent une acuité nouvelle à l’analyse des fondements et des manifestations de la latitude d’action des intermédiaires de l’action publique. Surtout, le regard porté aux activités réalisées dans les marges de l’action publique enrichit la compréhension des modalités complexes de diffusion des normes étatiques vers les populations gouvernées et des agencements sociaux qui fondent l’exercice et la portée de la puissance publique.
La socialisation au féminisme des étudiant·es par les médias après #MeToo
Authors: Albenga Viviane 
Published: May 2022

La socialisation au féminisme par les médias est un sujet dont l’acuité se renforce depuis le hashtag MeToo. Dans ce contexte, nous montrerons comment certains médias ont pu participer à la socialisation politique au féminisme d’étudiant·es. En replaçant ces effets socialisateurs par rapport aux socialisations familiales et nationales et à l’expérience des violences sexistes, l’article met en évidence que certains médias ont pu agir comme un processus de transformation de dispositions incorporées en dispositions politique. Nous analyserons ensuite les usages politiques de médias en termes de participation et d’information : d’une part, les usages des comptes Instagram féministes ; d’autre part, les effets de la combinaison d’informations politiques généralistes par les réseaux sociaux et Internet aussi bien que la radio et la télévision. Ce dernier usage diversifié est le fait d’étudiant·es avec un capital culturel plus élevé qui se réfèrent davantage à l’histoire du mouvement féministe et de sa production théorique.
