De sitter magnetic black hole dipole with a supersymmetric horizon
Authors: Astesiano Davide , Cacciatori S.L.
Published: December 2021

Abstract

We find a new non BPS solution in N = 2 D = 4 gauged supergravity coupled to U(1) gauge fields and matter. It consists in a closed universe with two extremal black holes of equal size, surrounding two singularities. They have opposite magnetic charges (and no electric charges), but stay in static equilibrium thanks to the positive pressure of a cosmological constant. The geometry is perfectly symmetric under the exchange of the black holes and the flip of the sign of the charges. However the scalar field is non constant and non symmetric, with different values at the horizons, which depend on a real modulus. Remarkably we show that it satisfies the attractor mechanism and the entropy indeed depends only on the magnetic charges. At one of the horizons the solution becomes $$ \frac{1}{2} $$

-BPS supersymmetric, while at the other one there is no supersymmetry, but the entropy remains independent from the scalar modulus.
Spatial tuning of translational optic flow responses in hawkmoths of varying body size
Authors: Grittner Rebecca , Baird Emily , Stöckl Anna
Published: December 2021

To safely navigate their environment, flying insects rely on visual cues, such as optic flow. Which cues insects can extract from their environment depends closely on the spatial and temporal response properties of their visual system. These in turn can vary between individuals that differ in body size. How optic flow-based flight control depends on the spatial structure of visual cues, and how this relationship scales with body size, has previously been investigated in insects with apposition compound eyes. Here, we characterised the visual flight control response limits and their relationship to body size in an insect with superposition compound eyes: the hummingbird hawkmoth Macroglossum stellatarum. We used the hawkmoths’ centring response in a flight tunnel as a readout for their reception of translational optic flow stimuli of different spatial frequencies. We show that their responses cut off at different spatial frequencies when translational optic flow was presented on either one, or both tunnel walls. Combined with differences in flight speed, this suggests that their flight control was primarily limited by their temporal rather than spatial resolution. We also observed strong individual differences in flight performance, but no correlation between the spatial response cutoffs and body or eye size.

Published: December 2021

Differentiation between penile squamous cell carcinoma patients who can benefit from limited organ-sparing surgery and those at significant risk of lymph node metastasis is based on histopathological prognostic factors including histological grade and tumor histological subtype. We examined levels of interobserver and intraobserver agreement in assessment of histological subtype and grade in 207 patients with penile squamous cell carcinoma. The cases were assessed by seven pathologists from three hospitals located in Sweden and Italy. There was poor to moderate concordance in assessing both histological subtype and grade, with Fleiss kappas of 0.25 (range: 0.02–0.48) and 0.23 (range: 0.07–0.55), respectively. When choosing HPV-associated and non-HPV-associated subtypes, interobserver concordance ranged from poor to good, with a Fleiss kappa value of 0.36 (range: 0.02–0.79). A re-review of the slides by two of the pathologists showed very good intraobserver concordance in assessing histological grade and subtype, with Cohen’s kappa values of 0.94 and 0.91 for grade and 0.95 and 0.84 for subtype. Low interobserver concordance could lead to undertreatment and overtreatment of many patients with penile cancer, and brings into question the utility of tumor histological subtype and tumor grade in determining patient treatment in pT1 tumors.
Geometric convergence results for closed minimal surfaces via bubbling analysis
Authors: Ambrozio Lucas , Buzano Reto , Carlotto Alessandro , Sharp Ben
Published: December 2021

We present some geometric applications, of global character, of the bubbling analysis developed by Buzano and Sharp for closed minimal surfaces, obtaining smooth multiplicity one convergence results under upper bounds on the Morse index and suitable lower bounds on either the genus or the area. For instance, we show that given any Riemannian metric of positive scalar curvature on the three-dimensional sphere the class of embedded minimal surfaces of index one and genus $$\gamma $$
γ
is sequentially compact for any $$\gamma \ge 1$$

γ

, away from finitely many points where curvature concentration may happen. This result exploits a sharp estimate on the multiplicity of convergence in terms of the number of ends of the bubbles that appear in the process.

Published: December 2021

Understanding fluid flows in planetary cores and subsurface oceans, as well as their signatures in available observational data (gravity, magnetism, rotation, etc.), is a tremendous interdisciplinary challenge. In particular, it requires understanding the fundamental fluid dynamics involving turbulence and rotation at typical scales well beyond our day-to-day experience. To do so, laboratory experiments are fully complementary to numerical simulations, especially in systematically exploring extreme flow regimes for long duration. In this review article, we present some illustrative examples where experimental approaches, complemented by theoretical and numerical studies, have been key for a better understanding of planetary interior flows driven by some type of mechanical forcing. We successively address the dynamics of flows driven by precession, by libration, by differential rotation, and by boundary topography.
Inclusivity insights: two urban development projects in Johannesburg
Authors: Hofer Edith , Musakwa Walter , van Lanen Sander , Gumbo Trynos , Netsch Stefan , Gugerell Katharina
Published: December 2021

Johannesburg, which is South Africa’s largest city and economic center, is still influenced by patterns of inequality of the past. Although spatial transformation has been rapid since 1994, spatial divisions along class lines are still prevalent long after the apartheid era. This is despite the fact that societal values such as inclusivity, spatial justice and equal access to resources have become the core goals of Johannesburg’s spatial and urban development. This is particularly true when addressing housing, public open spaces, transport and social infrastructure embedded in a suitable land-use mix. However, despite the adoption of numerous policies by government, this research indicates that even recent urban development projects such as Fleurhof and Waterfall are falling short in delivering those objectives. Based on a case study analysis, we show that significant dysfunctionalities become evident when evaluating these two projects, despite their meeting relevant indicators of spatial inclusion on paper. Tensions are identified between theoretical approaches and the implementation of societally relevant policy goals. These include inclusivity and spatial justice by mostly privatized provision of housing and services, and deficiencies in public maintenance of infrastructure. The research reveals, that ‘ticking-the-boxes’ behavior on policy and project level does not produce equitable, inclusive neighborhoods and urban spatial patterns, but rather reproduces spatial inequalities of the past. If these policies are to result in real spatial change and improvement in the lives of Johannesburg residents, a more proactive approach by the public sector at different levels will be necessary.
Closure Versus Non-closure of Hernia Defect in Laparoscopic Ventral Hernia Repair with Mesh: a Systematic Review
Authors: Aljohani Emad
Published: December 2021

There is a controversial premise about choosing a surgical approach in ventral hernia using laparoscopic repair. Some surgeons prefer to use mesh with closure while others prefer to use mesh without closure. This study aims to compare mainly the rate of recurrence in mesh repair with and without closure. A wide range of electronic bibliographic databases such as PubMed, Embase and Education Resources Information Center (ERIC) was searched. Based on the eligibility criteria, all studies which compared the results after hernia repair from 2010 to 2020 were incorporated. Following screening the abstracts, we ended up reviewing seven full-text articles, and data were extracted on important parameters such as demographic attributes of participants, sample size and recurrence rate of hernia. Of the total studies that were reviewed, three were randomized controlled trials (RCT’s) and four retrospective observational studies. The sample size of all included studies varied between 80 and 176. The findings appear promising for the fascial closure as it showed evidence of a significant reduction in the recurrence rate with P = 0.047 in one out of the three randomized controlled trials and in the retrospective observational studies reaching up to 16.7% recurrence reduction rate. Likewise, there is also a reduction in the bulging, surgical site infection and seroma formation with higher patient’s satisfaction and quality of life score. Primary fascial closure appears to be effective as it can decrease the rates of recurrence, seroma formation and bulging, and improve patient’s satisfaction and quality of life. Given the dearth of studies, mainly randomized controlled trials, there is a need to carry out large randomized controlled trials with enough follow-up.
Leveraging Hazard, Exposure, and Social Vulnerability Data to Assess Flood Risk to Indigenous Communities in Canada
Authors: Chakraborty Liton , Thistlethwaite Jason , Minano Andrea , Henstra Daniel , Scott Daniel
Published: December 2021

This study integrates novel data on 100-year flood hazard extents, exposure of residential properties, and place-based social vulnerability to comprehensively assess and compare flood risk between Indigenous communities living on 985 reserve lands and other Canadian communities across 3701 census subdivisions. National-scale exposure of residential properties to fluvial, pluvial, and coastal flooding was estimated at the 100-year return period. A social vulnerability index (SVI) was developed and included 49 variables from the national census that represent demographic, social, economic, cultural, and infrastructure/community indicators of vulnerability. Geographic information system-based bivariate choropleth mapping of the composite SVI scores and of flood exposure of residential properties and population was completed to assess the spatial variation of flood risk. We found that about 81% of the 985 Indigenous land reserves had some flood exposure that impacted either population or residential properties. Our analysis indicates that residential property-level flood exposure is similar between non-Indigenous and Indigenous communities, but socioeconomic vulnerability is higher on reserve lands, which confirms that the overall risk of Indigenous communities is higher. Findings suggest the need for more local verification of flood risk in Indigenous communities to address uncertainty in national scale analysis.
Atomically Dispersed Fe-Co Bimetallic Catalysts for the Promoted Electroreduction of Carbon Dioxide
Authors: Chen Zhangsen , Zhang Gaixia , Wen Yuren , Chen Ning , Chen Weifeng , Regier Tom , Dynes James , Zheng Yi , Sun Shuhui
Published: December 2021

The electroreduction reaction of CO2 (ECO2RR) requires high-performance catalysts to convert CO2 into useful chemicals. Transition metal-based atomically dispersed catalysts are promising for the high selectivity and activity in ECO2RR. This work presents a series of atomically dispersed Co, Fe bimetallic catalysts by carbonizing the Fe-introduced Co-zeolitic-imidazolate-framework (C–Fe–Co–ZIF) for the syngas generation from ECO2RR. The synergistic effect of the bimetallic catalyst promotes CO production. Compared to the pure C–Co–ZIF, C–Fe–Co–ZIF facilitates CO production with a CO Faradaic efficiency (FE) boost of 10%, with optimal FECO of 51.9%, FEH2 of 42.4% at − 0.55 V, and CO current density of 8.0 mA cm−2 at − 0.7 V versus reversible hydrogen electrode (RHE). The H2/CO ratio is tunable from 0.8 to 4.2 in a wide potential window of − 0.35 to − 0.8 V versus RHE. The total FECO+H2 maintains as high as 93% over 10 h. The proper adding amount of Fe could increase the number of active sites and create mild distortions for the nanoscopic environments of Co and Fe, which is essential for the enhancement of the CO production in ECO2RR. The positive impacts of Cu–Co and Ni–Co bimetallic catalysts demonstrate the versatility and potential application of the bimetallic strategy for ECO2RR.
Inventing Laziness
Authors: Hafez Melis
Published: December 2021

Neither laziness nor its condemnation are new inventions, however, perceiving laziness as a social condition that afflicts a 'nation' is. In the early modern era, Ottoman political treatises did not regard the people as the source of the state's problems. Yet in the nineteenth century, as the imperial ideology of Ottomanism and modern discourses of citizenship spread, so did the understanding of laziness as a social disease that the 'Ottoman nation' needed to eradicate. Asking what we can learn about Ottoman history over the long nineteenth-century by looking closely into the contested and shifting boundaries of the laziness - productivity binary, Melis Hafez explores how 'laziness' can be used to understand emerging civic culture and its exclusionary practices in the Ottoman Empire. A polyphonic involvement of moralists, intellectuals, polemicists, novelists, bureaucrats, and, to an extent, the public reveals the complexities and ambiguities of this multifaceted cultural transformation. Using a wide variety of sources, this book explores the sustained anxiety about productivity that generated numerous reforms as well as new understandings of morality, subjectivity, citizenship, and nationhood among the Ottomans.

Night on Earth
Authors: Rodogno Davide
Published: December 2021

Night on Earth is a broad-ranging account of international humanitarian programs in Central and Eastern Europe, the Balkans and the Near East from 1918 to 1930. Davide Rodogno shows that international 'relief' and 'development' were intertwined long before the birth of the United Nations with humanitarians operating in a region devastated by war and famine and in which state sovereignty was deficient. Influenced by colonial motivations and ideologies these humanitarians attempted to reshape entire communities and nations through reconstruction and rehabilitation programmes. The book draws on the activities of a wide range of secular and religious organisations and philanthropic foundations in the US and Europe including the American Relief Administration, the American Red Cross, the Quakers, Save the Children, the Near East Relief, the American Women's Hospitals, the League of Nations and the International Committee of the Red Cross.
Ideologies of Corporate Responsibility: From Neoliberalism to “Varieties of Liberalism”
Authors: Vallentin Steen , Murillo David
Published: December 2021

Critical scholarship often presents corporate social responsibility (CSR) as a reflection or embodiment of neoliberalism. Against this sort of sweeping political characterization we argue that CSR can indeed be considered a liberal concept but that it embodies a “varieties of liberalism.” Building theoretically on the work of Michael Freeden on liberal languages, John Ruggie and Karl Polanyi on embedded forms of liberalism, and Michel Foucault on the distinction between classical liberalism and neoliberalism, we provide a conceptual treatment and mapping of the ideological positions that constitute the bulk of modern scholarly CSR debate. Thus, we distinguish between embedded liberalism, classical liberalism, neoliberalism, and re-embedded liberalism. We develop these four orientations in turn and show how they are engaged in “battles of ideas” over the meaning and scope of corporate responsibilities—and how they all remain relevant for an understanding of contemporary debates and developments in the field of CSR and corporate sustainability.
It takes two to tango: The therapeutic alliance in community brain injury rehabilitation
Authors: Williams Liz M. , Douglas Jacinta M.
Published: December 2021

Objective:

A positive therapeutic (or working) alliance has been associated with better outcomes for clients in the psychotherapeutic and traumatic brain injury (TBI) rehabilitation literature. The aim of this pilot study was to gain an understanding of the therapeutic alliance in community rehabilitation from the perspectives of adults with TBI and their close others who have completed a community rehabilitation programme.

Method:

This study used a constructivist, qualitative methodology which applied grounded theory analysis techniques. Using purposeful sampling, three pairs of participants (adults with TBI and close others) who had finished a community rehabilitation programme completed separate in-depth interviews which were transcribed verbatim and progressively analysed using a process of constant comparison.

Results:

A preliminary framework illustrating participants’ experience of a therapeutic alliance was generated, comprising three interconnected themes: being recognised as an individual, working together and feeling personally connected. All participants viewed being able to work together as important in their experience of community rehabilitation and described features that helped and hindered the alliance.

Conclusion:

These pilot study results demonstrate the importance of the therapeutic alliance to the rehabilitation experience of individuals with TBI and those close to them.
Use of Big Data in Disaster Recovery: An Integrative Literature Review
Authors: Rosenblum Andrew J. , Wend Christopher M. , Akhtar Zohaib , Rosman Lori , Freeman Jeffrey D. , Barnett Daniel J.
Published: December 2021

Objective:

Disasters of all varieties have been steadily increasing in frequency. Simultaneously, “big data” has seen explosive growth as a tool in business and private industries while opportunities for robust implementation in disaster management remain nascent. To more explicitly ascertain the current status of big data as applied to disaster recovery, we conducted an integrative literature review.

Methods:

Eleven databases were searched using iteratively developed keywords to target big data in a disaster recovery context. All studies were dual-screened by title and abstract followed by dual full-text review to determine if they met inclusion criteria. Articles were included if they focused on big data in a disaster recovery setting and were published in the English-language peer-reviewed literature.

Results:

After removing duplicates, 25,417 articles were originally identified. Following dual title/abstract review and full-text review, 18 studies were included in the final analysis. Among those, 44% were United States-based and 39% focused on hurricane recovery. Qualitative themes emerged surrounding geographic information systems (GIS), social media, and mental health.

Conclusions:

Big data is an evolving tool for recovery from disasters. More research, particularly in real-time applied disaster recovery settings, is needed to further expand the knowledge base for future applications.
#BlackGirlMagic as Resistant Imaginary
Authors: Mason Qrescent Mali
Published: December 2021

This article concerns itself with the ways that Black women have taken up #BlackGirlMagic as a critical reimagining of their subject positionalities as Black women. I argue that #BlackGirlMagic is a resistant imaginary that has significantly altered the contemporary western social imaginary and suggest that the intersectional ambiguity that Black women animate builds community among Black women toward collective liberation. Bringing together Kimberlé Crenshaw's concept of intersectionality, Simone de Beauvoir's concept of ambiguity, and María Lugones's concept of oppressed←→resisting subjects, I argue that #BlackGirlMagic's so-called “magic” is both produced by and produces what José Medina has termed a guerrilla epistemology. In outlining the contours of this epistemology, I demonstrate how #BlackGirlMagic resists through the transmission of knowledge, the creation of a critical genealogy, its visionary orientation, and the development of an insurrectionary counterdiscourse. To illustrate, I briefly discuss how #BlackGirlMagic provides white women with an opportunity for a beneficial form of epistemic friction. In the end, I suggest that #BlackGirlMagic's ability to unite Black women transnationally bodes well for its continued effects on the western social imaginary.
Cut cotorsion pairs
Authors: Huerta Mindy , Mendoza Octavio , Pérez Marco A.
Published: December 2021

We present the concept of cotorsion pairs cut along subcategories of an abelian category. This provides a generalization of complete cotorsion pairs, and represents a general framework to find approximations restricted to certain subcategories. We also exhibit some connections between cut cotorsion pairs and Auslander–Buchweitz approximation theory, by considering relative analogs for Frobenius pairs and Auslander–Buchweitz contexts. Several applications are given in the settings of relative Gorenstein homological algebra, chain complexes, and quasi-coherent sheaves, as well as to characterize some important results on the Finitistic Dimension Conjecture, the existence of right adjoints of quotient functors by Serre subcategories, and the description of cotorsion pairs in triangulated categories as co-t-structures.
Weak Alfvénic turbulence in relativistic plasmas. Part 1. Dynamical equations and basic dynamics of interacting resonant triads
Authors: TenBarge J.M. , Ripperda B. , Chernoglazov A. , Bhattacharjee A. , Mahlmann J.F. , Most E.R. , Juno J. , Yuan Y. , Philippov A.A.
Published: December 2021

Alfvén wave collisions are the primary building blocks of the non-relativistic turbulence that permeates the heliosphere and low- to moderate-energy astrophysical systems. However, many astrophysical systems such as gamma-ray bursts, pulsar and magnetar magnetospheres and active galactic nuclei have relativistic flows or energy densities. To better understand these high-energy systems, we derive reduced relativistic magnetohydrodynamics equations and employ them to examine weak Alfvénic turbulence, dominated by three-wave interactions, in reduced relativistic magnetohydrodynamics, including the force-free, infinitely magnetized limit. We compare both numerical and analytical solutions to demonstrate that many of the findings from non-relativistic weak turbulence are retained in relativistic systems. But, an important distinction in the relativistic limit is the inapplicability of a formally incompressible limit, i.e. there exists finite coupling to the compressible fast mode regardless of the strength of the magnetic field. Since fast modes can propagate across field lines, this mechanism provides a route for energy to escape strongly magnetized systems, e.g. magnetar magnetospheres. However, we find that the fast-Alfvén coupling is diminished in the limit of oblique propagation.
Reconnection and particle acceleration in three-dimensional current sheet evolution in moderately magnetized astrophysical pair plasma
Authors: Werner Gregory R. , Uzdensky Dmitri A.
Published: December 2021

Magnetic reconnection, a plasma process converting magnetic energy to particle kinetic energy, is often invoked to explain magnetic energy releases powering high-energy flares in astrophysical sources including pulsar wind nebulae and black hole jets. Reconnection is usually seen as the (essentially two-dimensional) nonlinear evolution of the tearing instability disrupting a thin current sheet. To test how this process operates in three dimensions, we conduct a comprehensive particle-in-cell simulation study comparing two- and three-dimensional evolution of long, thin current sheets in moderately magnetized, collisionless, relativistically hot electron–positron plasma, and find dramatic differences. We first systematically characterize this process in two dimensions, where classic, hierarchical plasmoid-chain reconnection determines energy release, and explore a wide range of initial configurations, guide magnetic field strengths and system sizes. We then show that three-dimensional (3-D) simulations of similar configurations exhibit a diversity of behaviours, including some where energy release is determined by the nonlinear relativistic drift-kink instability. Thus, 3-D current sheet evolution is not always fundamentally classical reconnection with perturbing 3-D effects but, rather, a complex interplay of multiple linear and nonlinear instabilities whose relative importance depends sensitively on the ambient plasma, minor configuration details and even stochastic events. It often yields slower but longer-lasting and ultimately greater magnetic energy release than in two dimensions. Intriguingly, non-thermal particle acceleration is astonishingly robust, depending on the upstream magnetization and guide field, but otherwise yielding similar particle energy spectra in two and three dimensions. Although the variety of underlying current sheet behaviours is interesting, the similarities in overall energy release and particle spectra may be more remarkable.
Evolution of an arched magnetized laboratory plasma in a sheared magnetic field

Arched magnetized structures are a common occurrence in space and laboratory plasmas. Results from a laboratory experiment on spatio-temporal evolution of an arched magnetized plasma (

$\beta \approx 10^{-3}$

, Lundquist number

$\approx 10^{4}$

, plasma radius/ion gyroradius

$\approx 20$

) in a sheared magnetic configuration are presented. The experiment is designed to model conditions relevant to the formation and destabilization of similar structures in the solar atmosphere. The magnitude of a nearly horizontal overlying magnetic field was varied to study its effects on the writhe and twist of the arched plasma. In addition, the direction of the guiding magnetic field along the arch was varied to investigate its role in the formation of either forward- or reverse-S shaped plasma structures. The electrical current in the arched plasma was well below the current required to make it kink unstable. A significant increase in the writhe of the arched plasma was observed with larger magnitudes of overlying magnetic field. A forward-S shaped arched plasma was observed for a guiding magnetic field oriented nearly antiparallel to the initial arched plasma current, while the parallel orientation yielded the reverse-S shaped arched plasma.
The Relationship Between Conscious and Unconscious Intentionality
Authors: Majeed Raamy
Published: December 2021

The contemporary view of the relationship between conscious and unconscious intentionality consists in two claims: (i) unconscious propositional attitudes represent the world the same way conscious ones do, and (ii) both sets of attitudes represent by having determinate propositional content. Crane (2017) has challenged both claims, proposing instead that unconscious propositional attitudes differ from conscious ones in being less determinate in nature. This paper aims to evaluate Crane's proposal. In particular, I make explicit and critique certain assumptions Crane makes in support of his asymmetry, and argue for a conditional claim: if Crane is right that unconscious intentional states are (relatively) indeterminate, this suggests that conscious intentional states are indeterminate in a similar fashion as well.
How can we improve air pollution? Try increasing trust first
Authors: Hoffmann Bridget Lynn , Scartascini Carlos , Cafferata Fernando G.
Published: December 2021

Environmental policies are characterized by salient short-term costs and long-term benefits that are difficult to observe and to attribute to the government's efforts. These characteristics imply that citizens’ support for environmental policies is highly dependent on their trust in the government's capability to implement solutions and commitment to investments in those policies. Using novel survey data from Mexico City, we show that trust in the government is positively correlated with citizens’ willingness to support an additional tax approximately equal to a day's minimum wage to improve air quality and greater preference for government retention of revenues from fees collected from polluting firms. We find similar correlations using the perceived quality of public goods as a measure of government competence. These results provide evidence that mistrust can be an obstacle to better environmental outcomes.
An assessment of the Extractive Industries Transparency Initiative (EITI) using the Bayesian Corruption Indicator
Authors: Fenton Villar Paul
Published: December 2021

Advocated across the international community for more than 15 years, the Extractive Industries Transparency Initiative (EITI) is now widely recognised as a hallmark anti-corruption scheme in the extractive sector. This study presents an assessment of the relationship between EITI membership and countries’ progress in tackling corruption. It provides the first study that looks at this issue using a ‘state-of-the-art’ indicator called the Bayesian Corruption Indicator. It also introduces an innovative estimation strategy combining entropy balancing with a difference-in-difference framework to address the baseline inequalities that exist between member and non-member countries. Contrary to the findings of many leading studies, this analysis finds corruption scores have improved significantly among EITI member countries. In particular, the evidence is strongest when we examine a sub-group of EITI members designated fully compliant with the initiative's transparency standards.
On the multidimensionality of bilingualism and the unique role of language use
Authors: Kałamała Patrycja , Senderecka Magdalena , Wodniecka Zofia
Published: December 2021

The multidimensionality of the bilingual experience makes the investigation of bilingualism fascinating but also challenging. Although the literature distinguishes several aspects of bilingualism, the measurement methods and the relationships between these aspects have not been clearly established. In a group of 171 relatively young Polish–English bilinguals living in their first-language environment, this study investigates the relationships between the multiple measures of bilingualism. The study shows that language entropy – an increasingly popular measure of the diversity of language use – reflects a separate aspect of the bilingual experience from language-switching and language-mixing measures. The findings also indicate that language proficiency is not a uniform aspect of the bilingual experience but a complex construct that requires appropriately comprehensive measurements. Collectively, the findings contribute to the discussion on the best practices for quantifying bilingualism.
Anatomy of a Regional Civil War: Guangxi, China, 1967–1968
Authors: Walder Andrew G.
Published: December 2021

During the violent early years of China’s Cultural Revolution, the province of Guangxi experienced by far the largest death toll of any comparable region. One explanation for the extreme violence emphasizes a process of collective killings focused on households in rural communities that were long categorized as class enemies by the regime. From this perspective, the high death tolls were generated by a form of collective behavior reminiscent of genocidal intergroup violence in Bosnia, Rwanda, and similar settings. Evidence from investigations conducted in China in the 1980s reveals the extent to which the killings were part of a province-wide suppression of rebel insurgents, carried out by village militia, who also targeted large numbers of noncombatants. Guangxi’s death tolls were the product of a counterinsurgency campaign that more closely resembled the massacres of communists and suspected sympathizers coordinated by Indonesia’s army in wake of the coup that deposed Sukarno in 1965.

Creativity in an Affective Context
Authors: Perchtold-Stefan Corinna M. , Papousek Ilona , Rominger Christian , Fink Andreas
Published: December 2021

Abstract. Everyday life often requires considerable creativity in dealing with challenging circumstances. This implies that creativity regularly operates in an affective context, however, this “C” of creativity is rarely addressed in contemporary research. In this brief review article, we address some important milestones in this nascent field of research. Starting with early accounts on emotional creativity, we discuss seminal research intertwining creativity and mood states, and finally introduce two recent developments in this field: reappraisal inventiveness as the capacity to generate manifold cognitive reappraisals for aversive situations, and malevolent creativity as creative ideation intentionally used to damage others. We discuss the conceptual origins of reappraisal inventiveness and malevolent creativity and provide an extensive review of past behavioral and neuroscientific findings regarding these differently motivated instances of affective creativity. Additionally, novel pilot findings and prospects on both lines of research will be provided, which may help to advance investigations into more real-world applications of creative cognition.

Published: December 2021

Abstract. The current paper presents a detailed examination of a lay theory perspective on the Sensory-Processing-Sensitivity (SPS) personality profile within the Five-Factor Model (FFM) of personality. The lay SPS personality profile was assessed by asking self-identified highly sensitive people to rate themselves on a Five-Factor Model questionnaire (NEO-PI-3). We applied the NEO-PI-3 norms (domains and facets) and examined the inter-rater agreement of the facets. The sample consisted of 560 (female: 86.43%, Mage = 37.36 years, SDage = 6.64 years, 18.17–47.42 years) self-identified highly sensitive adults. Six facets, in particular, stood out with good and very good inter-rater agreement: participants fell within the highest 23% of the population on facets Fantasy, Aesthetics, Feelings (Openness to Experience); Anxiety, Depression (Neuroticism); and the lowest 23% of the population on the facet Gregariousness (Extraversion).

Summer rainfall in the southeast Prairie Pothole Region (SEPPR) is an important part of a vital wetland ecosystem that various species use as their habitat. We examine sources and pathways for summer rainfall moisture, large‐scale features influencing moisture delivery, and large‐scale connections related to summer moisture using the Hybrid Single‐Particle Lagrangian Integrated Trajectory (HYSPLIT) model. Analysis of HYSPLIT back trajectories shows that land is the primary moisture source for summer rainfall events indicating moisture recycling plays an important role in precipitation generation. The Great Plains Low‐Level Jet/Maya Express is the most prominent moisture pathway. It impacts events sourced by land and the Gulf of Mexico (GoM), the secondary moisture source. There is a coupling between land, atmosphere, and ocean conveyed by large‐scale climate connections between rainfall events and sea surface temperature (SST), Palmer Drought Severity Index, and 850‐mb heights. Land‐sourced events have a connection to the northern Pacific and northwest Atlantic Oceans, soil moisture over the central U.S., and low‐pressure systems over the SEPPR. GoM‐sourced events share the connection to soil moisture over the central U.S. but also show connections to SSTs in the North Pacific and Atlantic Oceans and the GoM, soil moisture in northern Mexico, and 850‐mb heights in the eastern Pacific Ocean. Both types of events show connections to high 850‐mb heights in the Caribbean which may reflect a connection to Bermuda High. These insights into moisture sources and pathways can improve skill in SEPPR summer rainfall predictions and benefit natural resource managers in the region.

The ROMA database (ROck reflectance for MArtian in situ exploration, https://roma.univ-lyon1.fr) provides the reflectance spectra between 0.4 and 3–4 μm of various terrestrial, Martian, and synthetic samples, as a means to document reference measurements for comparison with data acquired by visible and near‐infrared spectrometers on planetary surfaces, with a focus on current and future Martian observations by the Perseverance (Mars 2020 mission) and Rosalind Franklin (ExoMars) rovers. The main specificity of this database is to include a significant fraction of spectra of unprocessed rock, which are more realistic analogs and often have different spectral features than the fine powders more commonly analyzed in reflectance spectroscopy. Additionally, these measurements were acquired with a spectrometer whose spot size is similar to those of the SuperCam instrument (Mars 2020 mission) at a few meters from a target. Supplementary information are provided in the ROMA database: higher‐level data (such as absorption band parameters) as well as sample mineralogy estimated by whole‐rock X‐ray diffraction analyses. Future comparisons with this database will help improve the interpretation of spectral measurements acquired on the Martian surface. This work introduces the aim of the library and its current state, but additional data on intact natural rock surfaces will likely be added in the future.

Infrared sounding instruments use large arrays of detectors to make simultaneous observations in multiple field‐of‐view (FOV). For Numerical Weather Prediction (NWP) models to assimilate multiple detector observations, FOV responsivities should be well matched so that forecasts are not degraded due to dis‐similar FOV properties. In this pseudo‐observing system simulation experiment (OSSE) study, hyperspectral infrared observations are assimilated to assess the impact of FOV heterogeneity on analyses and forecasts. The Cross‐track Infrared Sounder (CrIS) was selected as the representative instrument because it is an operational instrument with the lowest noise. The use of CrIS to this study is only limited to its detector configuration, orbital parameters, magnitudes of the instrument noise, and detector‐to‐detector bias. Perturbations in radiance to simulate detector heterogeneity are modeled to be wavelength and detector dependent. Results show that detector heterogeneity can be detrimental to analyses and forecasts. The data thinning routine relies on the brightness temperature of a surface sensitive channel to determine which profiles are used. If the FOV heterogeneity results in an increase in the brightness temperature, the FOV will be preferred, and this extraneous information will be used. The variational bias correction scheme does not account for biases associated with different FOVs. Unremoved biases are assimilated as “information” resulting in a biased analysis. Biases propagate and grow with time as the global data assimilation system cycles. The bias correction coefficients of all satellite observations are solved simultaneously with the atmospheric state analysis. In this way, the detector biases can influence other satellite observations.

Understanding Differences in North Atlantic Poleward Ocean Heat Transport and Its Variability in Global Climate Models
Authors: Madonna Erica , Sandø Anne Britt
Published: December 2021

The ocean heat transport from the North Atlantic to the Barents Sea impacts the sea ice extent and the energy budget of the Arctic. The analyzed climate models from the fifth (CMIP5) and sixth (CMIP6) phases of the Coupled Model Intercomparison Project show large intermodel differences in the ocean heat transport with biases of several Terawatts at the Iceland‐Scotland Ridge and Barents Sea Opening (BSO). While both model generations show a large spread in mean volume transports, in CMIP6 temperatures are more homogeneous and realistic, yielding heat transports closer to observations. On all time scales, changes in heat transport reflect changes in volume transport, while temperature changes affect the heat transport variability on longer time scales, especially at the BSO. The temporal variability of heat and volume transports is linked to wind forcing south of Iceland and along the Norwegian coast in all models but has different magnitudes.

For the first time, near infrared (NIR) auroral emissions measured from space have been compared with E‐region coherent scatter. The E‐region coherent scatter observations were obtained by the 49.5 MHz Ionospheric Continuous‐wave E‐region Bistatic Experimental Auroral Radar (ICEBEAR) in western Canada. NIR emissions integrated over 650–1,100 nm wavelengths were obtained from the Fast Auroral Imager instrument onboard e‐POP on CASSIOPE (now Swarm‐E) with a 1 s temporal resolution (same as ICEBEAR), with the instrument slewed to the center of the ICEBEAR field‐of‐view. The coherent echoes and the NIR emissions are expected to originate below 120 km altitude. The radar spectra indicated that the turbulence was very weak. The location of all coherent echoes corresponded to NIR emission brightness values of more than 250 kR (kilo‐Rayleighs) and less than 1,250 kR. When the emissions were very bright, the electric fields were seemingly too weak to produce plasma instabilities, explaining why no radar echoes were detected. By contrast, even if the electric field happened to be relatively strong in dark regions, the background plasma densities were too small to generate detectable coherent scatter radar echoes. The Doppler shifts of the coherent scatter spectra were clustered around 465 and ± 250 m/s. These magnitudes did not agree with the quiet 350 m/s ion‐acoustic speed expected from the weaker electric fields that should have prevailed under weak turbulence situations. The unexpected Doppler shifts were potentially due to either unexpected strong electric fields and altitude variations, or ambient km‐size density gradients at 110 km.
