Background: Healthcare workers' (HCWs') travel-related anxiety needs to be assessed in light of the emergence of SARS-CoV-2 mutations.Methods: An online, cross-sectional questionnaire among HCWs between December 21, 2020 to January 7, 2021. The outcome variables were HCWs' knowledge and awareness of the SARS-CoV-2 B.1.1.7 lineage that was recently reported as the UK variant of concern, and its associated travel worry and Generalized Anxiety Disorder (GAD-7) score.Results: A total of 1,058 HCWs completed the survey; 66.5% were female, 59.0% were nurses. 9.0% indicated they had been previously diagnosed with COVID-19. Regarding the B.1.1.7 lineage, almost all (97.3%) were aware of its emergence, 73.8% were aware that it is more infectious, 78.0% thought it causes more severe disease, and only 50.0% knew that current COVID-19 vaccines are effective in preventing it. Despite this, 66.7% of HCWs were not registered to receive the vaccine. HCWs' most common source of information about the new variant was social media platforms (67.0%), and this subgroup was significantly more worried about traveling. Nurses were more worried than physicians (P = 0.001).Conclusions: Most HCWs were aware of the emergence of the SARS-CoV-2 B.1.1.7 variant and expressed substantial travel worries. Increased worry levels were found among HCWs who used social media as their main source of information, those with lower levels of COVID-19 vaccine uptake, and those with higher GAD-7 scores. The utilization of official social media platforms could improve accurate information dissemination among HCWs regarding the Pandemic's evolving mutations. Targeted vaccine campaigns are warranted to assure HCWs about the efficacy of COVID-19 vaccines toward SARS-CoV-2 variants.

Abstract (English)Good service cannot be separated from the role of service providers, namely government officials. The implementation of main duties and functions as government officials in providing good public services to the community is required to have adequate resources, the attitude of government officials which has an impact on the quality of services provided to the community who use services. The purpose of this study was to determine and analyze the performance of employees at the Pekanbaru City Investment and One Stop Integrated Service Service through a study on the implementation of building permit services with a focus on the performance of employees in realizing good service to the community. The research method used is qualitative and the data collection technique used in this research is descriptive qualitative. The results of this study indicate that the quality of employees is still not good, including there are some employees who are not in their place, while the community comes for their respective service needs, in other words, employees are not disciplined. There are inaccuracies in completing some tasks, as the researchers saw in field observations to obtain building permits and there is still a selective culture in its management.Abstrak (Indonesia)Pelayanan yang baik tidak lepas dari peran penyedia jasa yaitu aparatur pemerintah.

Published: May 2021

Abstract
Application of the radial velocity (RV) technique in the near-infrared is valuable because of the diminished impact of stellar activity at longer wavelengths, making it particularly advantageous for the study of late-type stars but also for solar-type objects. In this paper, we present the IGRINS RV open-source python pipeline for computing infrared RV measurements from reduced spectra taken with IGRINS, an R ≡ λ/Δλ ∼ 45,000 spectrograph with simultaneous coverage of the H band (1.49–1.80 μm) and K band (1.96–2.46 μm). Using a modified forward-modeling technique, we construct high-resolution telluric templates from A0 standard observations on a nightly basis to provide a source of common-path wavelength calibration while mitigating the need to mask or correct for telluric absorption. Telluric standard observations are also used to model the variations in instrumental resolution across the detector, including a yearlong period when the K band was defocused. Without any additional instrument hardware, such as a gas cell or laser frequency comb, we are able to achieve precisions of 26.8 m s−1 in the K band and 31.1 m s−1 in the H band for narrow-line hosts. These precisions are empirically determined by a monitoring campaign of two RV standard stars, as well as the successful retrieval of planet-induced RV signals for both HD 189733 and τ Boo A; furthermore, our results affirm the presence of the Rossiter–McLaughlin effect for HD 189733. The IGRINS RV pipeline extends another important science capability to IGRINS, with publicly available software designed for widespread use.
An Exploration of Three New Methods to Facilitate the Calculation of the Significance Levels of Periodogram Peaks by Simulation
Authors: Koen C. 
Published: May 2021

Abstract
At a given frequency ν, calculation of the periodogram entails evaluating two linear combinations

and

of the observations. It is pointed out that C and S are normally distributed even for relatively small numbers of observations. This can be used as a basis for simulating periodograms from a multivariate normal distribution with specified covariance structure. The advantage is that computationally expensive evaluations of sinusoids need to be performed only once—in the calculation of the covariances. Furthermore, the large covariance matrix can be factorized, and the factors replaced by low-rank approximations, which alleviates the computer memory demands. The second part of the paper discusses the choice of the degree of oversampling of the periodogram, i.e., the spacing

of the frequency grid over which it is calculated. It is shown using

, where ΔT is the time baseline of the observations, leads to an error of only about 1% in the percentiles of the distribution of maximum peak values. The third part of the paper deals with the representation of the distribution of periodogram maxima by the generalized extreme value distribution. Although the generalized extreme value form may formally differ highly significantly from the actual distribution of periodogram maxima, it is demonstrated that it may nonetheless be useful in practical terms. Results are illustrated throughout using three data sets with widely different aliasing properties.
The Emergence of Structure in the Binary Black Hole Mass Distribution
Authors: Tiwari Vaibhav , Fairhurst Stephen 
Published: May 2021

Abstract
We use the gravitational wave signals from binary black hole merger events observed by LIGO and Virgo to reconstruct the underlying mass and spin distributions of the population of merging black holes. We reconstruct the population using the mixture model framework VAMANA using observations in GWTC-2 occurring during the first two observing runs and the first half of the third run (O1, O2, and O3a). Our analysis identifies a structure in the chirp mass distribution of the observed population. Specifically, we identify peaks in the chirp mass distribution at 8, 14, 26, and 45 M
⊙ and a complementary structure in the component mass distribution with an excess of black holes at masses of 9, 16, 45, and 57 M
⊙. Intriguingly, for both the distributions, the location of subsequent peaks are separated by a factor of around two and there is a lack of mergers with chirp masses of 10–12 M
⊙. The appearance of multiple peaks is a feature of a hierarchical merger scenario when, due to a gap in the black hole mass spectrum, a pile-up occurs at the first peak followed by mergers of lower mass black holes to hierarchically produce higher mass black holes. However, cross-generation merger peaks and observations with high spins are also predicted to occur in such a scenario that we are not currently observing. The results presented are limited in measurement accuracy due to small numbers of observations but if corroborated by future gravitational wave observations these features have far-reaching implications.
Que pensent les habitants des territoires peu denses de la mobilité ? Une exploitation textuelle des données du Grand Débat National
Authors: Flipo Aurore 
Published: May 2021

Mise en place à la suite du mouvement des Gilets Jaunes au début de l’année 2019, la plateforme du Grand Débat a recueilli 569 000 contributions issues d’un peu plus de 250 000 contributeurs individuels (Bennani, Gandré, Monnery, 2019). Malgré de nombreuses limitations, qui sont abordées en préalable de l’analyse, cette large base de données peut constituer un outil de compréhension complémentaire des perceptions de l’action publique sur les territoires. Dans cet article, nous utilisons les contributions postées en ligne sur le site du Grand Débat pour analyser la manière dont l’objet mobilité est appréhendé dans deux territoires à dominante rurale, à l’aide d’une analyse textuelle. Nous nous intéressons d’abord aux thématiques générales dans lesquelles on trouve un discours sur la mobilité. Nous analysons ensuite la place de la question de la mobilité au sein de la thématique de la transition écologique, qui est celle qui a recueilli le plus de contributions portant sur la mobilité. Enfin, nous nous intéressons aux souhaits exprimés par les contributeurs sur l’accès à divers modes de transport sur leur territoire, avant de discuter des potentialités et des limites de l’outil d’analyse textuelle pour traiter les données de ce type. L’analyse montre un hiatus important entre les discours publics, centrés sur les pratiques et la responsabilité individuelles et l’importance dans le corpus d’un discours mettant en avant la dimension systémique de la transition écologique. Elle confirme également des clivages observés ailleurs au sujet de la voiture électrique.
Les miroirs aux princes au reflet des idées politiques de leur temps (XVI e et XVII e siècles)
Authors: Gendre Xavier 
Published: May 2021

L’expression « miroirs des princes » est communément utilisée pour décrire les traités politiques adressés au pouvoir royal dans le but d’exhorter le prince aux vertus, de le former et de le préparer à l’exercice du pouvoir, en y décrivant l’idéal de sa figure. Au-delà de l’emploi générique de l’expression métaphorique du miroir, la littérature politique des « miroirs des princes » a cependant été sujette à des ruptures qui ont non seulement consommé le genre de manière définitive mais surtout transformé l’exercice politique du pouvoir royal.
Le climat est-il une ressource ? Perspectives historiques à partir de la conception bioclimatique en architecture
Authors: Gaillard Clément 
Published: May 2021

Cet article vise à étudier dans quelles conditions le climat peut être considéré comme une ressource, à partir du développement de la conception bioclimatique en architecture. Il s’appuie sur l’étude d’archives et d’entretiens avec des acteurs, afin de montrer la manière dont cette méthode de conception s’est historiquement structurée suivant l’idée que le climat englobe un ensemble de ressources énergétiques potentiellement utiles. À la suite de cette analyse historique, l’article se concentre sur le cas du « gisement solaire » et des difficultés d’appréhension de cette ressource. Ces difficultés, ainsi que les problèmes d’équité dans l’accès à des apports climatiques favorables, traduisent le caractère équivoque de la ressource climatique, qui nous paraît être d’actualité.
L’Arbre colonne de Kitayama : comment passer d’une ressource matérielle à un paysage culturel ?
Authors: Jacquet Benoît , Urushima Andrea Flores 
Published: May 2021

Dans l’architecture japonaise, les poteaux en bois de cryptomère (Cryptomeria japonica) sont utilisés à Kyoto depuis le XVIe siècle dans les bâtiments de style sukiya, dans les alcôves décoratives (tokonoma) et certains détails des maisons urbaines (machiya). Ce bois de construction, le Kitayama sugi, provient d’un village dans les montagnes du nord de Kyoto, dont le paysage et l’agroforesterie sont en cours de classement en tant que « paysage culturel ». L’objectif de cette recherche est d’observer comment l’exploitation d’une ressource matérielle peut devenir un lieu reconnu pour le caractère exceptionnel de son paysage culturel. Cette étude est fondée sur une série d’entretiens, menés entre 2014 et 2021 dans une forêt de Kitayama sugi auprès d’un pépiniériste et négociant en bois. Il est l’un des derniers garants de la transmission de techniques et de savoirs, il témoigne de l’évolution de cette sylviculture depuis la fin du XXe siècle.
Le Sacre du stock
Authors: Landauer Paul 
Published: May 2021

Dans le champ de l’architecture, comme dans la plupart des secteurs d’activité du monde occidental contemporain, la part fonctionnelle du stock est invisibilisée. Partout la performance du flux tendu l’emporte. Les greniers et les entrepôts ont été remplacés par les sites de logistique. Les surfaces de vente ont envahi les réserves. Les logements ont vu la part dédiée au rangement se réduire. La transparence de l’open space s’étend jusqu’au cœur des immeubles de bureaux. Pourtant, l’architecture du stock résiste. Elle rejaillit, tel le retour du refoulé, dans le logement ; s’invite dans toutes les démarches qui prônent aujourd’hui le recyclage et la résilience ; devient un enjeu de pouvoir pour reconquérir une autonomie de production ; et s’impose de manière inattendue dans certaines des fonctionnalités les plus aiguës de la société hyperindustrielle comme les data centers. Les installations du stock, hier dépréciées et aujourd’hui abandonnées pourraient bien prendre leur revanche et (re) devenir les matrices du territoire de demain. L’architecture du stock retrouverait dès lors l’aura qui a été la sienne dans un grand nombre de civilisations d’avant la modernité ; une architecture dont Bernard Rudofsky, dans son exposition doublée d’un livre, Architecture Without Architects en 1964, a révélé la capacité à répondre à quatre aspirations humaines essentielles : le besoin de monument, la recherche d’un équilibre entre nomadisme et sédentarité, le souci de conjurer les risques et la propension pour le commun.
