Abstract
Line intensity mapping (LIM) provides a unique and powerful means to probe cosmic structures by measuring the aggregate line emission from all galaxies across redshift. The method is complementary to conventional galaxy redshift surveys that are object based and demand exquisite point-source sensitivity. The Tomographic Ionized-carbon Mapping Experiment (TIME) will measure the star formation rate during cosmic reionization by observing the redshifted [C ii] 158 μm line (6 ≲ z ≲ 9) in the LIM regime. TIME will simultaneously study the abundance of molecular gas during the era of peak star formation by observing the rotational CO lines emitted by galaxies at 0.5 ≲ z ≲ 2. We present the modeling framework that predicts the constraining power of TIME on a number of observables, including the line luminosity function and the auto- and cross-correlation power spectra, including synergies with external galaxy tracers. Based on an optimized survey strategy and fiducial model parameters informed by existing observations, we forecast constraints on physical quantities relevant to reionization and galaxy evolution, such as the escape fraction of ionizing photons during reionization, the faint-end slope of the galaxy luminosity function at high redshift, and the cosmic molecular gas density at cosmic noon. We discuss how these constraints can advance our understanding of cosmological galaxy evolution at the two distinct cosmic epochs for TIME, starting in 2021, and how they could be improved in future phases of the experiment.
Numerical Research on the Effect of the Initial Parameters of a CME Flux-rope Model on Simulation Results. II. Different Locations of Observers
Authors: Shen Fang , Liu Yousheng , Yang Yi 
Published: July 2021

Abstract
In numerical studies of the initiation and propagation of coronal mass ejections (CMEs), it has been proven that the shape, size, and plasma parameters of CMEs could significantly affect simulation results and subsequent space weather predictions. In our previous research, we proposed a new way to initiate a CME based on the graduated cylindrical shell model, and studied the effect of different initial parameters of CMEs on the simulation results when the observer is aligned with the initial propagation direction of the CME. In this paper, we investigate the influence of the different initial parameters of CMEs on simulation results at the observational points with different longitudes and latitudes. Our results indicate that as long as the initial mass of the CME remains unchanged, the initial geometric thickness will have a different influence in the latitudinal and longitudinal directions. The deflection of the CMEs always occurs in both latitudinal and longitudinal directions, when the CMEs interact with the background solar wind structures, such as the corotating interaction region, in the heliosphere.
Sensitivity Study of r-process Abundances to Nuclear Masses
Authors: Jiang 姜 X. F. 晓飞 , Wu 吴 X. H. 鑫辉 , Zhao 赵 P. W. 鹏巍 
Published: July 2021

Abstract
The impact of nuclear mass uncertainties on the r-process abundances has been systematically studied with the classical r-process model by varying the mass of every individual nucleus in the range of ±0.1 to ±3.0 MeV based on six different mass models. A new quantitative relation between the uncertainties of r-process abundances and those of the nuclear masses is extracted, i.e., a mass uncertainty of ±0.5 MeV would lead to an abundance uncertainty of a factor around 2.5. It is found that this conclusion holds true for various mass models.
Machine Learning the Sixth Dimension: Stellar Radial Velocities from 5D Phase-space Correlations

Published: July 2021

Abstract
The Gaia satellite will observe the positions and velocities of over a billion Milky Way stars. In the early data releases, the majority of observed stars do not have complete 6D phase-space information. In this Letter, we demonstrate the ability to infer the missing line-of-sight velocities until more spectroscopic observations become available. We utilize a novel neural network architecture that, after being trained on a subset of data with complete phase-space information, takes in a star’s 5D astrometry (angular coordinates, proper motions, and parallax) and outputs a predicted line-of-sight velocity with an associated uncertainty. Working with a mock Gaia catalog, we show that the network can successfully recover the distributions and correlations of each velocity component for stars that fall within ∼5 kpc of the Sun. We also demonstrate that the network can accurately reconstruct the velocity distribution of a kinematic substructure in the stellar halo that is spatially uniform, even when it comprises a small fraction of the total star count.

Published: July 2021

Abstract
We have combined laboratory, modeling, and observational efforts to investigate the chemical and microphysical processes leading to the formation of the cloud system that formed at an unusually high altitude (>250 km) over Titan’s south pole after the northern spring equinox. We present here a study focused on the formation of C6H6 ice clouds at 87°S. As the first step of our synergistic approach, we have measured, for the first time, the equilibrium vapor pressure of pure crystalline C6H6 at low temperatures (134–158 K) representative of Titan’s atmosphere. Our laboratory data indicate that the experimental vapor pressure values are larger than those predicted by extrapolations found in the literature calculated from higher-temperature laboratory measurements. We have used our experimental results along with temperature profiles and C6H6 mixing ratios derived from observational data acquired by the Cassini Composite Infrared Spectrometer (CIRS) as input parameters in the coupled microphysics radiative transfer Community Aerosol and Radiation Model for Atmospheres (CARMA). CARMA simulations constrained by these input parameters were conducted to derive C6H6 ice particle size distribution, gas volume mixing ratios, gas relative humidity, and cloud altitudes. The impact of the vapor pressure on the CIRS data analysis and in the CARMA simulations was investigated and resulted in both cases in benzene condensation occurring at lower altitude in the stratosphere than previously thought. In addition, the stratospheric C6H6 gas abundances predicted with the new saturation relationship are ∼1000× higher than previous calculations between 150–200 km, which results in larger particle sizes.

Published: July 2021

ObjectiveTreatment guidelines for rheumatoid arthritis (RA) include a patient-centered approach and shared decision making, which includes a discussion of patient goals. We describe the iterative early development of a structured goal elicitation tool to facilitate goal communication for persons with RA and their clinicians.MethodsTool development occurred in 3 phases: (1) clinician feedback on the initial prototype during a communication training session; (2) semistructured interviews with RA patients; and (3) community stakeholder feedback on elements of the goal elicitation tool in a group setting and electronically. Feedback was dynamically incorporated into the tool.ResultsClinicians (n = 15) and patients (n = 10) provided feedback on the tool prototypes. Clinicians preferred a shorter tool deemphasizing goals outside of their perceived treatment domain or available resources; they highlighted the benefits of the tool to facilitate conversation but raised concerns regarding current constraints of the clinic visit. Patients endorsed the utility of such a tool to support agenda setting and preparing for a visit. Clinicians, patients, and community stakeholders reported the tool was useful but identified barriers to implementation that the tool could itself resolve.ConclusionA goal elicitation tool for persons with RA and their clinicians was iteratively developed with feedback from multiple stakeholders. The tool can provide a structured way to communicate patient goals within a clinic visit and help overcome reported barriers such as time constraints. Incorporating a structured communication tool to enhance goal communication and foster shared decision making may lead to improved outcomes and higher-quality care in RA.

ObjectiveTo standardize and improve the accuracy of detection of arthritis by thermal imaging.MethodsChildren with clinically active arthritis in the knee or ankle, as well as healthy controls, were enrolled to the development cohort; another group of children with knee symptoms was enrolled to the validation cohort. Ultrasound was performed in the arthritis subgroup for the development cohort. Joint exam by certified rheumatologists was used as a reference for the validation cohort. Infrared thermal data were analyzed using custom software. Temperature after within-limb calibration (TAWiC) was defined as the temperature differences between joint and ipsilateral mid-tibia. TAWiC of knees and ankles was evaluated using ANOVA across subgroups. Optimal thresholds were determined by receiver-operating characteristic analysis using Youden index.ResultsThere were significant differences in mean and 95th TAWiC of knee in anterior, medial, lateral views, and of ankles in anterior view, between inflamed and uninflamed counterparts (P< 0.05). The area under the curve was higher by 30% when using TAWiCkneethan that when using absolute temperature. Within the validation cohort, the sensitivity of accurate detection of arthritis in the knees using both mean and 95th TAWiC from individual views or all 3 views combined ranged from 0.60 to 0.70, and the specificity was > 0.90 in all views.ConclusionChildren with active arthritis or tenosynovitis in knees or ankles exhibited higher TAWiC than healthy joints. Our validation cohort study showed promise for the clinical utility of infrared thermal imaging for arthritis detection.
Le soignant imaginaire
Authors: Marin Catherine 
Published: July 2021

Construire un idéal soignant est important, il est à la source de la motivation à soigner. Mais construire et déconstruire, ajuster cet idéal au réel est nécessaire et peut être au bout du compte libérateur. On peut être, dans le soin, ignorant de certaines choses et compétent par ailleurs, insuffisant et dévoué, ou encore fragile et fort. N’est-ce pas cette humilité qui nous aide à prévenir les risques graves de l’épuisement professionnel face à l’inéluctable de la mort ?
La vulnérabilité au cœur de celui qui soigne en soins palliatifs
Authors: Robo Arlette 
Published: July 2021

Il serait confortable d’aller vers une pensée primaire qui opposerait sur un mode manichéen, d’un côté les patients, souffrants, vulnérables ; et de l’autre, les soignants, « sachants » et tout-puissants. Une telle approche binaire écarterait toute la dialectique et la complexité qui participent à la relation soignant-soigné. Dans cette rencontre, plusieurs registres de l’être sont mobilisés et entretiennent la porosité des frontières soignant-soigné.
What Are the Pleasures of a Slave? The Politics of Affect in Antebellum US Slave Narratives
Authors: Marsoin Édouard 
Published: July 2021

Les récits d’esclaves sont des récits de souffrance qui ne vont pas sans joie. Si les souffrances des esclaves ont fait l’objet de nombreuses études, cet article se propose d’explorer leur contrepoint : plaisirs et joies qui, via leur mise en récit, acquièrent une dimension politique. Pour les esclaves, aucun plaisir n’est innocent, tout plaisir est politique, voire biopolitique, partie prenante des mécanismes disciplinaires des maîtres, qui font que leurs plaisirs peuvent être à la fois complices du système disciplinaire et signes de jouissance propre. Néanmoins, face aux régulations biopolitiques des plaisirs des esclaves, les récits d’esclaves peuvent produire un contre-discours politique via la mise en récit de « maigres joies » et plaisirs alternatifs, qui acquièrent une valeur infrapolitique et subjectivante.
Elizabeth Stoddard’s Depravity
Authors: Looby Christopher 
Published: July 2021

« I was moved and governed by my sensations », déclare Cassandra Morgeson, la narratrice de The Morgesons (1862) d’Elizabeth Stoddard. Cassandra est franche et ne s’excuse pas de son goût pour le plaisir et les expériences sensorielles extrêmes. Sa passion de la lecture nourrit et guide ce goût dépravé des sensations violentes. The Morgesons, à son tour, est un roman qui célèbre de manière autoréflexive les romans pour leur capacité à donner du plaisir, et tente de donner à ses lecteurs et lectrices toutes sortes de plaisirs sensoriels. Il dépeint également avec soin ce que l’on considère habituellement comme des moments successifs dans l’histoire de la sexualité. Ces moments sont compris comme chronologiquement simultanés mais géographiquement répartis en différents lieux de Nouvelle-Angleterre, entre lesquels Cassandra évolue.
The Pleasures of a Saint, the Pleasures of a Plant: William James, Walt Whitman, and the Varieties of Hedonic Experience
Authors: Jonik Michael 
Published: July 2021

Cet article prend pour point de départ les explorations du plaisir et de la volonté de William James dans ses Principes de psychologie (1890). Il montre comment James valorise l’approche optimiste des phénomènes de Walt Whitman comme un exemple de « religion de l’esprit sain » (« religion of healthy-mindedness ») et, plus tard, comme un panthéisme moniste et un empirisme proto-radical pluraliste. Je montre comment James juxtapose les plaisirs de Whitman aux plaisirs de la perception régénérée et de l’extase ascétique chez les saints chrétiens, ainsi qu’à la théorie panpsychique de Gustav Fechner concernant les plaisirs des plantes. À travers les figures de Whitman, du saint et de la plante, James souligne à la fois les variétés de l’expérience du plaisir et une réceptivité tempéramentale au plaisir qui dénote une vie digne d’être vécue.
Renforcer la capacité administrative dans les États en développement au Chili et à Singapour : une perspective comparative
Authors: Shamsul Haque M. , Puppim de Oliveira José A. 
Published: July 2021

La capacité administrative dépend de la nature de l’état, dont le système administratif fait partie intégrante. Ces dernières années, on a assisté à une reprise des débats sur le rôle de l’administration publique dans les États en développement en Asie du Sud-Est et en Amérique latine. Une composante analytique majeure des États en développement concerne leur capacité administrative et la manière de la renforcer. Il existe d’importantes variations dans la capacité administrative entre les États en développement, qui s’expliquent par les divergences de leurs contextes historiques, économiques, politiques et culturels. Dans le présent article, nous comparons deux cas transcontinentaux (Singapour et le Chili) sur le plan de la formation des États en développement et de la manière dont ils façonnent leurs systèmes administratifs et leurs initiatives de renforcement des capacités. Nous examinons les divergences dans la formation de ces États et les facteurs contextuels qui affectent leur capacité administrative. Nous concluons cet article avec quelques généralisations, afin de proposer un cadre analytique pour des recherches plus approfondies et suggérons des politiques nécessaires pour la mise en place d’une capacité administrative efficace. Remarques à l’intention des praticiens Le présent article souligne l’importance du renforcement des capacités administratives pour le développement. Nous étudions la mesure dans laquelle ces capacités sont façonnées par la formation de l’État dans le cadre duquel l’administration publique fonctionne. En expliquant cette relation entre la formation de l’État et l’administration publique, notre article s’intéresse spécifiquement à l’État « promoteur », compare deux cas transcontinentaux (Singapour et le Chili) en ce qui concerne la manière dont ces deux États-promoteurs diffèrent et provoquent des variations dans leurs systèmes administratifs, et explique les principaux facteurs contextuels qui conduisent à ces variations. Cette compréhension est essentielle pour concevoir des politiques efficaces de renforcement des capacités administratives dans tout pays en fonction de la formation de son État et de son contexte.
Observations de pratiques de professeurs-stagiaires. Quelles évolutions des savoirs professionnels ?
Authors: Jean Alain 
Published: July 2021

La formation des enseignants a subi de nombreuses réformes ces dernières années. L’observation des pratiques des professeurs stagiaires, au travers de l’activité qu’ils déploient en situation de classe, pourrait permettre de repérer un certain nombre de savoirs professionnels en cours d’élaboration ou de stabilisation. Cet article propose de donner quelques résultats d’une recherche longitudinale menée en 2011, qui consistait à observer les pratiques d’enseignants débutants pendant une année scolaire. Des enregistrements vidéo de classe et des autoconfrontations ont été menés régulièrement avec trois professeurs stagiaires sur leur lieu de stage en responsabilité. De façon plus précise, notre question de recherche portait sur les évolutions des pratiques repérables et observables. Quelles formes peuvent prendre ces évolutions de pratiques ? Quel type de développement professionnel est en œuvre chez les enseignants stagiaires ? Quels éléments construisent ces pratiques, ces développements professionnels et quelles sont les évolutions de ces éléments durant l’année scolaire particulière que vivent ces enseignants en formation par alternance ? L’article se centre sur les savoirs professionnels mobilisés par ces enseignants débutants et sur leur évolution pendant l’année scolaire.

Published: July 2021

Cet article rend compte de recherches sur les évaluations nationales de CM2 en français et en mathématiques et plus précisément sur leur passation effective en classe. En nous appuyant sur une première modélisation des séances d’évaluation, sur des observations en classe, des entretiens avec des enseignants et l’étude des prescriptions, nous analysons la mise en œuvre de ces épreuves et leurs spécificités disciplinaires. Nous mettons ainsi en évidence l’instabilité du cadrage disciplinaire de ces évaluations, la variabilité des modes d’actualisation du protocole de passation et les tensions relatives à la gestion temporelle des séances. Nos conclusions reviennent sur des questions méthodologiques et des perspectives de recherche sur les évaluations institutionnelles.
Impact of a Peripheral Vascular Access Service on Device Use
Authors: Wells Celia , Zhang Ziya , Chan Christy , Brito Amy , Kohli-Seth Roopa 
Published: July 2021

Background
More than 1 billion peripheral vascular access devices are inserted annually worldwide with potential complications including infection, thrombosis, and vasculature damage. Vasculature damage can necessitate the use of central catheters, which carry additional risks such as central catheter–associated bloodstream infections. To address these concerns, one institution used expert nurses and a consult request system with algorithms embedded in the electronic medical record.

Objectives
To develop a uniform process for catheter insertion by means of a peripheral vascular access service dedicated to selecting, placing, and maintaining all inpatient peripheral catheters outside of the intensive care units.

Methods
Descriptive analysis and χ2 analysis were done to describe the impact of the peripheral vascular access service.

Results
In 2018, 6246 consults were reviewed. Of these, 26% did not require vascular access. Similarly, in 2019, 7861 consults were reviewed, and 35.3% did not require vascular access. Use of central catheters decreased from 21% in 2017 to 17% in 2018 and 2019.

Conclusions
The peripheral vascular access service allowed patients to receive appropriate peripheral vascular access devices and avoid unnecessary peripheral catheter placements. This may have preserved patients’ peripheral vasculature and thus prevented premature central catheter placement and contributed to an overall decrease in central catheter days. With the peripheral vascular access service, peripheral vascular access devices were selected, placed, and maintained by experts with a standardized process that promoted a culture of quality and patient safety.
Association of p73 G4C14-A4T14 and p53 codon 72 polymorphism with cervical cancer in Chinese population
Authors: Guo Haiyan , Wen Zhang , Yang Shaodi , Qi Hongyan 
Published: July 2021

Background:
Cervical cancer is known to be the fourth most common cancer among women globally. In various factors, genetic factors have been considered as one major risk factor for cervical cancer. The research of genetic susceptibility to cervical cancer can be greatly helpful in studying the complex mechanism. This study was conducted to identify whether polymorphic variants of p73 G4C14-A4T14 and tumor protein p53 (p53) codon 72, either independently or jointly, might be associated with the risk of cervical cancer.

Methods:
The genotypes of p73 G4C14-A4T14 and p53 codon 72 polymorphisms of peripheral blood DNA from 190 cervical cancer patients and 210 controls were investigated using polymerase chain reaction with confronting two-pair primers and polymerase chain reaction-restriction fragment length polymorphism, respectively.

Results:
The frequency of p73 G4C14-A4T14 AT/AT (P = 0.013) or p53 codon 72 GG (P = 0.026) genotype was associated with an increased risk of cervical cancer by comparing with the p73 G4C14-A4T14 GC/GC or p53 codon 72 CC genotype, respectively. In addition, the interaction between the p73 G4C14-A4T14 and p53 codon 72 polymorphisms increased the risk of cervical cancer in a multiply manner, with the odds ratio being 3.692 (95% confidence interval =2.106-6.473) for subjects carrying both p73 G4C14-A4T14 GC/AT+AT/AT and p53 codon 72 GG genotypes.

Conclusion:
These results suggest that there is a statistical difference between p73 and p53 gene polymorphism and the risk of cervical cancer in Chinese women, and there is a potential gene-gene interaction in the incidence of cervical cancer.
