Published: October 2020

ABSTRACTObjectives:Our purpose was to determine the intensive care units’ (ICU’s) medical staff surge capacity during the coronavirus disease 2019 (COVID-19) outbreak in Spring 2020 in Spain.Methods:A multicenter retrospective survey was performed addressing the medical specialties present in the ICUs and the increase in bed capacity during this period.Results:Sixty-seven centers (62.04%) answered the questionnaire. The ICU bed capacity during the pandemic outbreak increased by 160% (95% confidence interval [CI], 128.97-191.03%). The average number of beds per intensive care medicine (ICM) specialist was 1.5 ± 0.60 and 3.71 ± 2.44 beds/specialist before and during the COVID-19 outbreak, respectively. Non-ICM specialists and residents were present in 50 (74.63%) and 23 (34.3%) ICUs during the outbreak, respectively. The number of physicians (ICM and non-ICM residents and specialists) in the ICU increased by 89.40% (95% CI, 64.26114.53%). The increase in ICM specialists was, however, 4.94% (95% CI, −1.35-11.23%). Most non-ICM physicians were anesthetists, followed by pediatricians and cardiologists.Conclusions:The majority of ICUs in our study were able to rapidly expand critical care capacity by adapting areas outside of the normal ICU to manage critically ill patients, and by extending the critical care staff with noncritical care physicians working as force multipliers.
Velvet fists: The paradox of defence diplomacy in Southeast Asia
Authors: Chang Jun Yan , Jenne Nicole 
Published: October 2020

AbstractDefence diplomacy represents a notable paradox. On the one hand, it is a cooperative activity to build strategic and moralistic trust between states and thus positively shape the environment in which foreign policy is made. On the other hand, defence diplomacy also involves competition and demonstrations of military power, which may contravene its goal of building moralistic trust and undermine confidence between states. This article deals with the latter competitive realpolitik elements of defence diplomacy in terms of secrecy, swaggering, and shows of force that have largely been ignored in the literature. Building on a theoretical discussion of whether defence diplomacy works, the case of peacekeeping in Southeast Asia is analysed to illustrate how defence diplomatic activities produce effects contrary to their stated aims.
At the outer limits of the international: Orbital infrastructures and the technopolitics of planetary (in)security
Authors: Peoples Columba , Stevens Tim 
Published: October 2020

AbstractAs staples of science fiction, space technologies, much like outer space itself, have often been regarded as being ‘out there’ objects of international security analysis. However, as a growing subset of security scholarship indicates, terrestrial politics and practices are ever more dependent on space technologies and systems. Existing scholarship in ‘astropolitics’ and ‘critical astropolitics’ has tended to concentrate on how such technologies and systems underpin and impact the dynamics of military security, but this article makes the case for wider consideration of ‘orbital infrastructures’ as crucial to conceptions and governance of planetary security in the context of the ‘Anthropocene’. It does so by outlining and analysing in detail Earth Observation (EO) and Near-Earth Object (NEO) detection systems as exemplary cases of technological infrastructures for ‘looking in’ on and ‘looking out’ for forms of planetary insecurity. Drawing on and extending recent theorisations of technopolitics and of Large Technical Systems, we argue that EO and NEO technologies illustrate, in distinct ways, the extent to which orbital infrastructures should be considered not only part of the fabric of contemporary international security but as particularly significant within and even emblematic of the technopolitics of planetary (in)security.

AbstractBackground:Critical shortages of personal protective equipment, especially N95 respirators, during the coronavirus disease 2019 (COVID-19) pandemic continues to be a source of concern. Novel methods of N95 filtering face-piece respirator decontamination that can be scaled-up for in-hospital use can help address this concern and keep healthcare workers (HCWs) safe.Methods:A multidisciplinary pragmatic study was conducted to evaluate the use of an ultrasonic room high-level disinfection system (HLDS) that generates aerosolized peracetic acid (PAA) and hydrogen peroxide for decontamination of large numbers of N95 respirators. A cycle duration that consistently achieved disinfection of N95 respirators (defined as ≥6 log10 reductions in bacteriophage MS2 and Geobacillus stearothermophilus spores inoculated onto respirators) was identified. The treated masks were assessed for changes to their hydrophobicity, material structure, strap elasticity, and filtration efficiency. PAA and hydrogen peroxide off-gassing from treated masks were also assessed.Results:The PAA room HLDS was effective for disinfection of bacteriophage MS2 and G. stearothermophilus spores on respirators in a 2,447 cubic-foot (69.6 cubic-meter) room with an aerosol deployment time of 16 minutes and a dwell time of 32 minutes. The total cycle time was 1 hour and 16 minutes. After 5 treatment cycles, no adverse effects were detected on filtration efficiency, structural integrity, or strap elasticity. There was no detectable off-gassing of PAA and hydrogen peroxide from the treated masks at 20 and 60 minutes after the disinfection cycle, respectively.Conclusion:The PAA room disinfection system provides a rapidly scalable solution for in-hospital decontamination of large numbers of N95 respirators during the COVID-19 pandemic.
Ideological Vote and Electoral Performance of the Bolivian MAS, 2002–2014
Authors: Luján Diego 
Published: October 2020

ABSTRACTSince 2005, the Movement Toward Socialism (MAS) has become a predominant party in the Bolivian party system. Despite its origin as a small, indigenous, and peasant-based party, the MAS has achieved an electoral performance unprecedented in Bolivian political history. What accounts for its electoral rise? Unlike available explanations based on sociostructural, institutional, or contextual factors, this article argues that ideological location decisions served as a signaling device that allowed the MAS to differentiate itself from its competitors. In so doing, the party managed to transcend the border of ethnic and regional cleavages, appealing to a broader electorate, which contributed decisively to its electoral success. Using data from public opinion surveys and based on statistical models, this article shows that ideology was pivotal in Bolivians’ decisions to vote for the MAS, particularly during the early period of its electoral takeoff.
The estimation of γ-ray Doppler factor forFermi/LAT-detected blazars
Authors: Pei Zhiyuan , Fan Junhui , Yang Jianghe , Bastieri Denis 
Published: October 2020

AbstractBlazars are a subclass of active galactic nuclei with extreme observation properties, which is caused by the beaming effect, expressed by a Doppler factor ($\delta$), in a relativistic jet. Doppler factor is an important parameter in the blazars paradigm to indicate all of the observation properties, and many methods were proposed to estimate its value. In this paper, we present a method following Mattox et al. to calculate the lower limit on$\gamma$-ray Doppler factor ($\delta_{\gamma}$) for 809 selectedFermi/LAT-detected$\gamma$-ray blazars by adopting the available$\gamma$-ray and X-ray data. Our sample included 342 flat-spectrum radio quasars (FSRQs) and 467 BL Lac objects (BL Lacs), out of which 507 sources are compiled with available radio core-dominance parameter (R) from our previous study. Our calculation shows that the average values of the lower limit on$\delta_{\gamma}$for FSRQs and BL Lacs are$\left\langle\delta_{\gamma}|_{\textrm{FSRQ}}\right\rangle = 6.87 \pm 4.07$and$\left\langle\delta_{\gamma}|_{\textrm{BL\ Lac}}\right\rangle=4.31 \pm 2.97$, respectively. We compare and discuss our results with those from the literature. We found that the derived lower limit on$\delta_{\gamma}$for some sources is higher than that from the radio estimation, which could be possibly explained by the jet bending within those blazars. Our results also suggest that the$\gamma$-ray and radio regions perhaps share the same relativistic effects. The$\gamma$-ray Doppler factor has been found to be correlated with both the$\gamma$-ray luminosity and core-dominance parameter, implying that the jet is possibly continuous in the$\gamma$-ray bands, andRis perhaps an indicator for a beaming effect.
COVID-19 and the Politics of Crisis
Authors: Lipscy Phillip Y. 
Published: October 2020

AbstractThe COVID-19 pandemic presents an opportunity to refocus scholarly attention on the politics of crisis. Crises that abruptly upend political and economic relations are important and increasing in frequency. However, the division of international relations into international political economy (IPE) and international security has contributed to the relative neglect of non-militarized crises like pandemics. Crises are defined by threat, uncertainty, and time pressure: understanding them requires a careful examination of how these variables affect political and economic outcomes. Drawing on often disparate literatures on finance, energy and climate change, natural disasters, pandemics, and violent conflict, I propose a broad research program around the politics of crisis, focusing on puzzles related to causes, responses, and transformations.
Language assessment tools for Arabic-speaking heritage and refugee children in Germany

Published: October 2020

AbstractThough Germany has long provided education for children speaking a heritage language and received two recent waves of refugees, reliable assessment tools for diagnosis of language impairment or the progress in the acquisition of German as a second language (L2) by refugee children are still lacking. The few tools expressly targeting bilingual populations are normed for younger, early successive bilingual children. This study investigates 27 typically developing children with Arabic as first language (L1), comparing 15 school-age Syrian refugees (6;6–12;8), with 12 heritage speakers (6;0–12;9). We assess the L1 and L2 skills of these two groups with standardized tests, but crucially with an Arabic and a German sentence repetition (SRT) as well as a nonword (NWRT) repetition task (Grimm & Hübner, in press; Marinis & Armon-Lotem, 2015). Comparable scores emerged only for German LITMUS-NWRT and Arabic LITMUS-SRT. Refugee children had an advantage in L1 measures, for example, vocabulary and morphosyntactic production, whereas they performed poorly in the German LITMUS-SRT and other L2 tests involving morphosyntax and vocabulary even with 24 months of systematic exposure. This indicates that the acquisition of adequate vocabulary and complex syntax takes time. The paper explores factors influencing performance on the repetition tasks and relates the results to established diagnostic procedures and educational policies.
When Europe hits the subnational authorities: the transposition of EU directives in Germany between 1990 and 2018
Authors: Paasch Jana , Stecker Christian 
Published: October 2020

AbstractFederalism and the associated multi-level polity-structure have been frequently blamed for delaying the implementation of European Union (EU) directives. However, this verdict is incomplete as only a few studies open the “black box” of federalism to analyse the involvement of subnational parliaments and executives or second chambers in policy implementation. This article fills this gap and explains the transposition delay on the level of each individual implementation measure. Our novel data set covers about 850 directives and the corresponding 1,950 implementation measures between 1990 and 2018 in Germany. Using logistic regression models, we find that involving the subnational authorities substantially delays transposition. Subnational measures are three times more likely to be delayed than national ones. The effect of the veto power of a second chamber remains inconclusive. Our findings highlight the challenges federalism poses for the multi-level implementation of EU policies and have implications for the broader literature on compliance with public policies.
(Dis)agreements in the management of conservation conflicts in the Calakmul Biosphere Reserve, Mexico

Published: October 2020

SummaryTo manage widespread conservation conflicts, building a shared understanding among the parties involved has been considered key. However, there is little empirical evidence of the role this understanding might play in the context of imposed biosphere reserves. Using semi-structured and in-depth interviews in two communities within the Calakmul Biosphere Reserve, we explored whether or not there is a shared understanding of conflicts between local people and reserve managers, and we analysed its contribution to conflict management. We found that a shared understanding is not a determining factor when the conflict solution demands actions that exceed stakeholders’ functions. While a shared understanding helps with the global process of conflict management, there are other challenges: local impairment resulting from the exclusionary creation and the operation of protected areas and the need for action to solve a conflict that exceeds the functions of stakeholders.
Arata Isozaki: the architect as artist
Authors: Cho Hyunjung 
Published: October 2020

This paper is not a comprehensive survey of the architectural career of Arata Isozaki, one of the most distinguished practicing architects in the world today and the 2019 winner of the Pritzker Prize, but a specific look at his formative years of the 1960s when he began to build his own design methodology. It delineates Isozaki’s encounter with the avant-garde art movement of the 1960s, collectively called “Anti-Art, ” against the backdrop of the “anti-spirit” of Japanese society. Although Isozaki’s artistic side has been overstated at times, previous studies rarely addressed how his intensive interactions with art circles played a role in shaping his design methodology. I would like to examine the convergence of creative individuals and cross-disciplinary connections to understand Isozaki’s architectural thinking.This study examines how Isozaki’s collaborations with his artist contemporaries enabled him to formulate the notion of the “invisible city, ” a radically new design concept characterised by the expansion of the nature of architecture from producing isolated built-forms to all-encompassing natural and manmade environments. However, after drawing on communications and information theory, which prevailed in 60s architectural circles, Isozaki’s destructive and anarchistic connotation of “invisible city” was channeled into a systematic cybernetic model and eventually transformed into a constructive planning method. I will discuss the realisation of a cybernetic environment at the Festival Plaza of Expo’ 70 and trace the legacy of “invisible city” in his later postmodern work.
How is Brazil facing the crisis of Food and Nutrition Security during the COVID-19 pandemic?

Published: October 2020

AbstractThe goal of this commentary is to expose the situation of Food and Nutrition Security (FNS) in Brazil in the context of the COVID-19 pandemic by providing a critical analysis of this scenario and suggesting ways to move forward. When COVID-19 arrived in Brazil, a crisis scenario that incorporated economic, social and political aspects became highly visible. This scenario fostered unemployment, poverty and hunger. Besides that, it exposed multiple vulnerabilities that were getting worse over the past few years prior to the pandemic. In this context, COVID-19 found in Brazil a fertile ground for its dissemination and community transmission. The impacts of the suspension of many commercial activities and other economic sectors due to the pandemic were quickly felt socially and economically in Brazil. Some of the actions carried out by the Brazilian government included the emergency aid payment and exemption from payment of energy bills for vulnerable individuals, release of funds for programmes for the direct purchase of food from family farmers, delivery of school food kits directly to students despite the closure of schools and publication of sanitary rules for the operation of restaurants. However, these actions are still insufficient, slow and not sufficiently coordinated to contain the progress of the food and nutritional insecurity crisis in Brazil. The COVID-19 pandemic highlights the urgency for the Brazilian government to again prioritise the FNS agenda. This includes implementing mechanisms to ensure the Human Right to Adequate Food and expanding existing FNS programmes.

Published: October 2020

AbstractInterstellar carbon has been detected in both gas-phase molecules and solid particles. The goal of this study is to identify the link between these two phases of cosmic carbon. Here we report preliminary results on the low temperature formation of carbonaceous dust grains from gas-phase aromatic hydrocarbon precursors. This is done using the supersonic expansion of an argon jet seeded with aromatic molecules and exposed to an electrical discharge. We report experimental evidence of efficient carbon dust condensation from aromatic molecules including benzene and naphthalene. The molecular content of the solid grains is probed with laser desorption mass spectrometry. The mass spectra reveal a rich molecular composition including fragments of the parent molecule but also growth into larger molecular species.
Dust in debris disk: Observations and laboratory experiments
Authors: Olofsson Johan 
Published: October 2020

AbstractDebris disks are the natural by-products of the star and planet formation processes. Since the 1980’s several thousands of debris disks have been detected, and the presence of a disk is inferred by the detection of excess emission over the photospheric emission. This thermal emission arises from (micron-sized or slightly bigger) dust grains heated by the central star. However, in the vast majority of cases, these observations are not spatially resolving the radial distribution of the dust, resulting in strong degeneracies in the modeling approach (radial distance vs minimum grain size mostly). Therefore the properties of the small dust grains remained largely unconstrained until the arrival of high angular resolution instruments, especially at optical and near-infrared wavelengths. In these proceeding some of the main results are presented that have been obtained over the past few years on the properties of small dust grains in debris disks, and it is discussed how laboratory experiments contributed to put those results in context.
Low temperature gas phase reaction rate coefficient measurements: Toward modeling of stellar winds and the interstellar medium

Published: October 2020

AbstractStellar winds of Asymptotic Giant Branch (AGB) stars are responsible for the production of ∼85% of the gas molecules in the interstellar medium (ISM), and yet very few of the gas phase rate coefficients under the relevant conditions (10 – 3000 K) needed to model the rate of production and loss of these molecules in stellar winds have been experimentally measured. If measured at all, the value of the rate coefficient has often only been obtained at room temperature, with extrapolation to lower and higher temperatures using the Arrhenius equation. However, non-Arrhenius behavior has been observed often in the few measured rate coefficients at low temperatures. In previous reactions studied, theoretical simulations of the formation of long-lived pre-reaction complexes and quantum mechanical tunneling through the barrier to reaction have been utilized to fit these non-Arrhenius behaviours of rate coefficients.Reaction rate coefficients that were predicted to produce the largest change in the production/loss of Complex Organic Molecules (COMs) in stellar winds at low temperatures were selected from a sensitivity analysis. Here we present measurements of rate coefficients using a pulsed Laval nozzle apparatus with the Pump Laser Photolysis - Laser Induced Fluorescence (PLP-LIF) technique. Gas flow temperatures between 30 – 134 K have been produced by the University of Leeds apparatus through the controlled expansion of N2 or Ar gas through Laval nozzles of a range of Mach numbers between 2.49 and 4.25.Reactions of interest include those of OH, CN, and CH with volatile organic species, in particular formaldehyde, a molecule which has been detected in the ISM. Kinetics measurements of these reactions at low temperatures will be presented using the decay of the radical reagent. Since formaldehyde and the formal radical (HCO) are potential building blocks of COMs in the interstellar medium, low temperature reaction rate coefficients for their production and loss can help to predict the formation pathways of COMs observed in the interstellar medium.
Learning mid-IR emission spectra of PAH populations from observations
Authors: Foschino Sacha , Berné Olivier , Joblin Christine 
Published: October 2020

AbstractObservations of the mid-infrared (mid-IR, 3-15 μm) spectra of photo-dissociation regions reveal ubiquitous, broad and intense emission bands, the aromatic infrared bands (AIBs), attributed to polycyclic aromatic hydrocarbons (PAHs). Studies of the AIBs showed spectral variations (e.g. in the band positions) between different astrophysical objects, or even within single object, thanks to hyperspectral images. The James Webb Space Telescope (JWST) will allow to get further spectral and spatial details compared to former space observatories. This will come with large data sets, which will require specific tools in order to perform efficient scientific analysis.We propose in this study a method based on blind signal separation to reduce the analysis of such large data set to that of a small number of elementary spectra, spectrally representative of the data set and physically interpretable as the spectra of populations of mid-IR emitters. The robustness and fastness of the method are improved compared to former algorithms. It is tested on a ISO-SWS data set, which approaches the best the characteristics of JWST data, from which four elementary spectra are extracted, attributed to cationic, neutral PAHs, evaporating very small grains and large and ionized PAHs.
