Anthropogenic Disturbances and the Emergence of Native Diseases: a Threat to Forest Health
Authors: Burgess Treena I. , Oliva Jonàs , Sapsford Sarah J. , Sakalidis Monique L. , Balocchi Felipe , Paap Trudy
Published: April 2022

Purpose of Review

Human-caused global change is fundamentally altering natural forest ecosystems. More trees are exhibiting a wide range of symptoms indicative of poor vigour, particularly stressed species at the edge of their native ranges and stands growing on marginal sites. This review will focus on complex tree diseases (declines) caused by native pathogens and the key environmental drivers that contribute to this phenomenon. These systems are frequently complex, with multiple drivers at work.

Recent Findings

Using four cases studies on different continents, we explored the direct and indirect environmental drivers underlying these decline syndromes. Although climate and weather events seem to be usually associated with forest decline, we found that environmental disturbance by either forest management or land-use changes is also a global predisposing factor of decline which deserves more attention. Changes in land use have directly benefited pathogens such as root rots in the Pyrenees (Spain) or indirectly by making the environment more conducive for canker and foliar diseases in Australia and the USA. Focus on land-use changes could improve understanding of current decline problems such as those affecting Araucaria in Chile.

The next century will almost certainly see an unprecedented rise in forest pathogen epidemics, requiring a proactive rather than reactive response. Diseases caused by native pathogens with complex aetiologies will become more common, and recognising, characterising and managing these epidemics are difficult because native pathogens are frequently already widespread, and eradication is not feasible. We need to start approaching these issues from a ‘whole ecosystem’ perspective, highlighting the many aspects and entanglements of forest declines and allowing us to respond with management options tailored to each scenario. The approach proposed here provides logical steps based on six questions to untangle the direct and indirect environmental drivers of tree declines.
Effect of layered joints on rockburst in deep tunnels
Authors: He Mingming , Zhao Jinrui , Deng Bianyuan , Zhang Zhiqiang
Published: April 2022

The existence of joints in the surrounding rock mass has a considerable effect on tunnel rockbursts. Herein, we studied the effect of layered joints with different inclination angles and spacings on rockburst in deep tunnels and investigated the failure area, deformation process of the surrounding rock mass, stress change inside the surrounding rock mass, velocity of the failed rock, and the kinetic energy of the failure. The failure type of the surrounding rock mass can thus be determined. The results showed that the intensity of rockburst increases as rock quality designation (RQD) decreases, while the deformation rate of the surrounding rock mass first increases and then decreases. The deformation rate exhibits a turning point between RQD = 50 and 70, below which the deformation rate of the surrounding rock mass gradually decreases, ultimately ceasing to be a rockburst. Rockburst always occurs perpendicular to the direction of the joint. When σx = σy, as the joint inclination angle changes from 45° to 90°, the intensity of a rockburst first decreases (from 45° to 60°), and then increases (from 60° to 90°). When combined with the evolution law of stress and strain energy, the rockburst process can be divided into four stages.
New priorities for academic integrity: equity, diversity, inclusion, decolonization and Indigenization
Authors: Eaton Sarah Elaine
Published: April 2022

The topics of equity, diversity, inclusion, decolonization, and Indigenization have been neglected in academic and research integrity. In this article, I offer examples of how these issues are being addressed and argue that academic integrity networks and organizations ought to develop intentional strategies for equity, diversity and inclusion, and decolonization in terms of leadership, scholarship, and professional opportunities. I point out that existing systems perpetuate the conditions that allow for overrepresentation of reporting among particular student groups including international students, students of colour, and those for whom English is an additional language. I conclude with concrete recommendations for action.
The film festival sector and its networked structures of gender inequality
Authors: Ehrich Martha E. , Burgdorf Katharina , Samoilova Zhenya , Loist Skadi
Published: April 2022

The global film industry is shaped by gender inequality. Women are structurally underrepresented in professional roles that include high levels of creative and economic decision-making power, such as directors, writers, and producers. In our study, we ask to what extent the film festival sector, a prestigious sub-field of the film industry, is structured by gender biases. To address this question, we conceptualize the festival sector as a one-mode network consisting of film festivals that are connected through screening the same film, and as a two-mode network consisting of films and festivals. The composition of film core creative teams (incl. directors, writers, and producers) varies by gender. While some films are made by mixed gender core creative teams, others are made by women-only or men-only core creative teams. We use data on 1323 films that circulate among 1523 festivals and apply network analysis to describe and disentangle the structural facets that underlie persistent gender inequality in the film festival sector. In the first step, we analyze to what extent the one-mode film festival network is connected through the circulation of films with varying gender compositions, and what festivals occupy broker positions in this network. In the second step, we analyze to what extent films of different gender compositions are equally distributed across the overall festival landscape. For the first step, we find that the festival network connected through films by women-only core creative teams is much sparser in comparison to the network connected through films by men-only core creative teams. We also find that the majority of festivals obtaining important broker positions in the network, has not signed the 5050 × 2020 Gender Parity Pledge, which has important policy implications. For the second step, we find that films by men-only core creative teams are on average screened at more festivals as compared to films by women-only core creative teams, and that the degree of distribution of films by men-only core creative teams is much more skewed indicating a more pronounced festival hit dynamic.
Technology-Based Methods for Training Counseling Skills in Behavioral Health: a Scoping Review
Authors: Magill Molly , Mastroleo Nadine R. , Martino Steve
Published: April 2022

In the present review, we consider technology-based methods for training and monitoring counseling skills in behavioral health (i.e., addictions, mental health, and behavioral medicine). We provide an overview of topical foci and design features, as well as review the available research. The Arksey and O’Malley framework for scoping review was used and there were two project phases. First, we reviewed and charted design features and training topics. Second, we reviewed and charted published research evaluating training outcomes. The search process yielded six commercial companies or academic research centers targeting online training of behavioral health counseling skills. These programs could be categorized by an avatar (i.e., computer-generated) or video (i.e., human actor) client interface, as well as by a completely interactive experience (i.e., virtual reality) or an experience with a pre-programmed, branch-logic interaction (i.e., computer simulation). One final company provided monitoring services only, without an explicit training component. The literature in this area is in its nascent stages, with primarily pilot scope and comparatively less progress if contrasted with fields such as general medicine. Online training and monitoring of behavioral health counseling skills is a promising emerging field with positive qualities such as scalability, resource efficiency, and standardization. Future research should emphasize (1) between-group randomized clinical trials, (2) comparisons to standard training practices, and (3) alignment with professional competency standards.

Determining which species are at greatest risk, where they are most vulnerable, and what are the trajectories of their communities and populations is critical for conservation and management. Globally distributed, wide-ranging whales and dolphins present a particular challenge in data collection because no single research team can record data over biologically meaningful areas. Flukebook.org is an open-source web platform that addresses these gaps by providing researchers with the latest computational tools. It integrates photo-identification algorithms with data management, sharing, and privacy infrastructure for whale and dolphin research, enabling the global collaborative study of these global species. With seven automatic identification algorithms trained for 15 different species, resulting in 37 species-specific identification pipelines, Flukebook is an extensible foundation that continually incorporates emerging AI techniques and applies them to cetacean photo identification through continued collaboration between computer vision researchers, software engineers, and biologists. With over 2.0 million photos of over 52,000 identified individual animals submitted by over 250 researchers, the platform enables a comprehensive understanding of cetacean populations, fostering international and cross-institutional collaboration while respecting data ownership and privacy. We outline the technology stack and architecture of Flukebook, its performance on real-world cetacean imagery, and its development as an example of scalable, extensible, and reusable open-source conservation software. Flukebook is a step change in our ability to conduct large-scale research on cetaceans across biologically meaningful geographic ranges, to rapidly iterate population assessments and abundance trajectories, and engage the public in actions to protect them.
Hypolipidemic effect of chromium-modified enzymatic product of sulfated rhamnose polysaccharide from Enteromorpha prolifera in type 2 diabetic mice
Authors: Wang Xinyu , Ye Han , Cui Jiefen , Chi Yongzhou , Liu Ruizhi , Wang Peng
Published: April 2022

Sulfated rhamnose polysaccharide (SRP) derived fromEnteromorpha proliferais a metal-ion chelating agent that could potentially be used to treat diabetes. The aim of our study was to determine the effect of a variant of SRP on DIABETES. First, we synthesized and characterized SRPE-3 chromium(III) [SRPE-3-Cr(III)] complex using an enzymatic method. The maximum chelation rate was 18.2% under optimal chelating conditions of pH 6.0, time 4 h, and temperature 60 °C. Fourier transform infrared spectroscopy results showed important sites for Cr(III)-binding were O–H and C=O groups. We then studied the hypolipidemic effects of SRPE-3-Cr(III) on type 2 diabetes mellitus (T2DM) induced by a high-fat, high-sucrose diet (HFSD). Decreased blood glucose content, body fat ratio, serum TG, TC, LDL-C, and increased serum HDL-C were observed after treatment with SRPE-3-Cr(III). In addition, SRPE-3-Cr(III) significantly reduced leptin, resistin, and TNF-α levels, and increased adiponectin contents relative to T2DM. Histopathology results also showed that SRPE-3-Cr(III) could alleviate the HFSD-lesioned tissues. SRPE-3-Cr(III) also improved lipid metabolism via a reduction in aspartate aminotransferase, alanine aminotransferase, fatty acid synthase, and acetyl-CoA carboxylase activities in the liver. SRPE-3-Cr(III) at low doses exhibited better lipid-lowering activities, hence, could be considered to be a novel compound to treat hyperlipidemia and also act as an anti-diabetic agent.
Structural and electronic properties of Sn sheets grown on Cd(0001)

Published: April 2022

We investigate the growth and electronic properties of the Sn sheets on Cd(0001) with a low-temperature scanning tunneling microscopy (STM) and density functional theory (DFT) calculations. It is found that both the first and second layer of Sn reveal the epitaxial growth with a 1 × 1 commensurate lattice. Scanning tunneling microscopy (STS) measurements indicate the Sn monolayer exhibits a metallic behavior. DFT calculations indicate that all the Sn atoms in the first Sn layer occupy the energetically preferable hcp-hollow sites. Very small amount of charge is transferred from Cd(0001) to the Sn monolayer, indicating the interface of Sn/Cd(0001) is governed by the weak van der Waals interaction.
Energy supply based on wind-solar power in Germany
Authors: Lustfeld Hans
Published: April 2022

Wind-solar power has an intrinsic huge volatility and the obvious question arises, is it possible to marginalize it to an extent that the power generation can sufficiently be synchronized with the electric power consumption being volatile as well. We present a novel function describing the volatile system as a whole. The new function, in turn, depends on three characteristic numbers, which means that the volatility of this system is characterized by those numbers. Using the data of the total electric power consumption and the total wind-solar power generation in Germany for the last seven years (2015–2021) taken every 15 minutes we determine the characteristic numbers from these data and get the result that marginalizing the volatility is possible with a minimum of required storage capacity, provided (i) a surplus of wind-solar power is supplied about doubling the number of devices, (ii) smart meters are installed, (iii) a different kind of wind turbines and solar panels is partially used. Our results suggest that all the present electric energy required in Germany can be obtained from wind-solar power if (i), (ii) and possibly (iii) are fulfilled. And our results indicate that, because of the minimal necessary storage capacity, controlled wind-solar power can in addition produce the energy for transportation, warm water, space heating and in part for process heating, requiring an increase of the electric energy production in total by a factor of 5. Then, however, a huge number of wind turbines and solar panels is required changing the appearance of German landscapes fundamentally. Our method can be applied to the wind-solar power problem of any country provided a reliable basis of power data exists over a sufficiently long period.
A Distributed Attribute Reduction Algorithm for High-Dimensional Data under the Spark Framework
Authors: Wu Zhengjiang , Mei Qiuyu , Zhang Yaning , Yang Tian , Luo Junwei
Published: April 2022

Attribute reduction is an important issue in rough set theory. However, the rough set theory-based attribute reduction algorithms need to be improved to deal with high-dimensional data. A distributed version of the attribute reduction algorithm is necessary to enable it to effectively handle big data. The partition of attribute space is an important research direction. In this paper, a distributed attribution reduction algorithm based on cosine similarity (DARCS) for high-dimensional data pre-processing under the Spark framework is proposed. First, to avoid the repeated calculation of similar attributes, the algorithm gathers similar attributes based on similarity measure to form multiple clusters. And then one attribute is selected randomly as a representative from each cluster to form a candidate attribute subset to participate in the subsequent reduction operation. At the same time, to improve computing efficiency, an improved method is introduced to calculate the attribute dependency in the divided sub-attribute space. Experiments on eight datasets show that, on the premise of avoiding critical information loss, the reduction ability and computing efficiency of DARCS have been improved by 0.32 to 39.61% and 31.32 to 93.79% respectively compared to the distributed version of attribute reduction algorithm based on a random partitioning of the attributes space.
On the Appropriateness of Grief to Its Object
Authors: RATCLIFFE MATTHEW , RICHARDSON LOUISE , MILLAR BECKY
Published: April 2022

How we understand the nature and role of grief depends on what we take its object to be and vice versa. This paper focuses on recent claims by philosophers that grief is frequently or even inherently irrational or inappropriate in one or another respect, all of which hinge on assumptions concerning the proper object of grief. By emphasizing the temporally extended structure of grief, we offer an alternative account of its object that undermines these assumptions and dissolves the apparent problems. The principal object of grief, we suggest, is a loss of life possibilities, which is experienced, understood, and engaged with over a prolonged period. Other descriptions of grief's object identify more specific aspects of this loss in ways that do not respect a straightforward distinction between concrete and formal objects.
MODERN LIFE-CARE TONTINES
Authors: Hieber Peter , Lucas Nathalie
Published: April 2022

The tendency of insurance providers to refrain from offering long-term guarantees on investment or mortality risk has shifted attention to mutual risk pooling schemes like (modern) tontines, pooled annuities or group self annuitization schemes. While the literature has focused on mortality risk pooling schemes, this paper builds on the advantage of pooling mortality and morbidity risks, and their inherent natural hedge. We introduce a modern “life-care tontine”, which in addition to retirement income targets the needs of long-term care (LTC) coverage for an ageing population. In contrast to a classical life-care annuity, both mortality and LTC risks are shared within the policyholder pool by mortality and morbidity credits, respectively. Technically, we rely on a backward iteration to deduce the smoothed cashflows pattern and the separation of cash-flows in a fixed withdrawal and a surplus from the two types of risks. We illustrate our results using real life data, demonstrating the adequacy of the proposed tontine scheme.

Antimicrobial use during the coronavirus disease 2019 (COVID-19) pandemic at a tertiary-care center was analyzed using interrupted time-series analysis. Among intravenous antimicrobials, the use of azithromycin and third-generation cephalosporins significantly decreased during the current pandemic. Similarly, the use of oral antimicrobials, including azithromycin and fluoroquinolones, also decreased.
Corporate Governance In Russian State-Owned Enterprises: Real Or Surreal?
Authors: Nurgozhayeva Roza
Published: April 2022

The narrative that defines privatisation, corporatisation, and the separation of ownership and regulatory functions as the key prerequisites for a successful state-owned enterprises’ (SOE) governance structure represents the literature's leading approach. This approach has been embedded in national laws and policies across many countries. Nonetheless, some legal scholars have scrutinised and questioned this single-minded perspective, emphasising the impact of existing institutional conditions and calling for an alternative understanding of corporate governance dynamics in different SOEs. Notwithstanding a vigorous debate on SOEs, it almost exclusively focuses on China, while Russia, being another large state-driven economy, has been missing. This article fills this gap and offers a comparative and critical perspective on the state ownership system in Russia. The analysis of Russian SOEs reveals classic governance and incentive problems attributable to state ownership. However, the question is how despite close affiliation to the State and high transaction costs caused by state interference, Russian SOEs have gained a substantial international market presence. This article answers this paradox.
A playground for compressible natural convection with a nearly uniform density
Authors: Alboussière Thierry , Curbelo Jezabel , Dubuffet Fabien , Labrosse Stéphane , Ricard Yanick
Published: April 2022

In the quest to understand the basic universal features of compressible convection, one would like to disentangle genuine consequences of compression from spatial variations of transport properties. For instance, one may choose to consider a fluid with uniform dynamic viscosity, but, then, compressible effects will generate a density gradient and consequently the kinematic viscosity will not be uniform. In the present work, we consider a very peculiar equation of state, whereby entropy is solely dependent on density, so that a nearly isentropic fluid domain is nearly isochoric. Within this class of equations of state, there is a thermal adiabatic gradient and a key property of compressible convection is still present, namely its capacity to viscously dissipate a large fraction of the thermal energy involved, of the order of the well-named dissipation number. In the anelastic approximation, under the assumption of an infinite Prandtl number, the number of governing parameters can be brought down to two, the Rayleigh number and the dissipation number. This framework is proposed as a playground for compressible convection, an opportunity to extend the vast corpus of theoretical analyses on the Oberbeck–Boussinesq equations regarding stability, bifurcations or the determination of upper bounds for the turbulent heat transfer. Here, in a two-dimensional geometry, we concentrate on the structure of numerical solutions. For all Rayleigh numbers, a change in the vertical temperature profile is observed in the range of dissipation number between

$0$

and less than

$0.4$

, associated with the weakening of ascending plumes. For larger dissipation numbers, the heat flux dependence on this number is found to be well predicted by Malkus's model of critical layers. For dissipation numbers of order unity, and large Rayleigh numbers, dissipation becomes related to the entropy heat flux at each depth, so that the vertical dissipation profile can be predicted, and so does the total ratio of dissipation to convective heat flux.
New records of injured Cambrian and Ordovician trilobites
Authors: Bicknell Russell D.C. , Smith Patrick M. , Howells Thomas F. , Foster John R.
Published: April 2022

Records of abnormal fossil arthropods present important insight into how extinct forms responded to traumatic damage and developmental complications. Trilobites, bearing biomineralized dorsal exoskeletons, have arguably the most well-documented record of abnormalities spanning the Cambrian through the end-Permian. As such, new records of malformed, often injured, trilobites are occasionally identified. To further expand the documentation of abnormal specimens, we describe malformed specimens of Lyriaspis sigillum Whitehouse, 1939, Zacanthoides sp. indet., Asaphiscus wheeleri Meek, 1873, Elrathia kingii (Meek, 1870), and Ogygiocarella debuchii (Brongniart, 1822) from lower Paleozoic deposits. In considering these forms, we propose that they illustrate examples of injuries, and that the majority of these injuries reflect failed predation. We also considered the origin of injuries impacting singular segments, suggesting that these could reflect predation, self-induced damage, or intraspecific interactions during soft-shelled stages. Continued examination of lower Paleozoic trilobite injuries will further the understanding of how trilobites functioned as prey and elucidate how disparate trilobite groups recovered from failed attacks.
Step by Step: American Interracialism and the Origins of Talk-First Activism
Authors: Kenaston Connor S.
Published: April 2022

The idea that friendship and dialogue are the first steps to making a better world has a history. During the first half of the twentieth century, American Protestants powered a national movement for dialogue and cooperation among people of different races. In the 1940s and 1950s, Black leaders in predominantly white ecumenical Protestant institutions created a series of workshops and dialogue guides that popularized the notion that interracial exchange would lead to action. Backed by their institutions’ financial, moral, and organizational resources, they transformed both the interracial movement and dominant understandings of how to change society. Yet, while Black ecumenical leaders insisted that facilitating interracial exchange was just the beginning form of action in ending discrimination, they unintentionally facilitated problematic assumptions about the standalone power of “first steps” in creating a more equitable society.
Mental Stress, Workplaces and Nigeria's Employees’ Compensation Act
Authors: Nwankwo Prince Ifeanyi
Published: April 2022

It has been over a decade since the Employees’ Compensation Act (ECA) came into force, introducing, for the first time under Nigeria's employees’ compensation scheme, mental stress as a basis for compensation. However, legal literature on salient aspects of Nigerian employees’ compensation remains scant. This article seeks to bridge this gap and provide a source of legal scholarship to aid the adjudication of mental stress claims in Nigeria. The article discusses when and how work-related mental stress is compensable within the context of the ECA. It finds that, notwithstanding the subjective nature of mental stress and the possibility of feigning mental injury, the ECA establishes broad bases for compensating mental stress, increasing the risk that employees may manipulate the system and obtain benefits even when mental stress is not work-related. The article therefore articulates criteria to defeat fraudulent claims and ensure that only legitimate mental stress claims are compensated.
Sensitivity and Specificity of Spanish Prehospital Advanced Triage Method (META)
Authors: Castro Delgado Rafael , Gan Rick Kye , Cabrera García Víctor , Arcos González Pedro
Published: April 2022

Introduction:

Mass-casualty incident (MCI) triage systems aim to provide the best possible health care to the greatest number of affected people with the available resources in the context of a mass-casualty event. The Spanish Prehospital Advanced Triage Method (Modelo Extrahospitalario de Triaje Avanzado; META) was designed to improved patient sorting in MCIs.

Objective:

The aim of this study was to estimate and compare sensitivity and specificity of META and the Manchester Triage System (MTS) in MCIs by retrospectively applying both triage algorithms to real MCI patients from the Emergency and Disaster Research Unit (Unidad de Investigación en Emergencia y Desastres; UIED) MCI database.

Method:

This was a comparative study of two triage methods using sensitivity and specificity with the Revised Trauma Score (RTS) as the gold standard. A total of 134 MCI patients from the UIED database were included. An MCI in Asturias is defined as an incident that involves four or more victims that require ambulance mobilization.

Results:

Patients mean age was 39.85 years (95% CI, 35.9-43.8) with an age range from one to 88 years old. In total, 54.4% of the patients were female. The most common types of MCI involved were fires (51.0%), followed by road traffic accident (43.3%) and street fight (3.7%). For MTS, the overall sensitivity was 30.6% (95% CI, 22.9-39.1) and specificity was 66.0% (95% CI, 60.0-71.7). For META triage algorithm, the overall sensitivity was 79.9% (95% CI, 72.1-86.3) and specificity was 89.9% (95% CI, 85.7-93.3).

Conclusion:

The META triage algorithm is a reliable triage system; thus, it can be recommended to be used in an MCI.
Health Care Organizations’ Interoperability during Multi-Organizational Disaster Management: A Scoping Review
Authors: Gastaldi Silvana , Horlait Melissa
Published: April 2022

Introduction:

Disaster management (DM) is becoming increasingly complex because of technological advancement and the multi-organization and international contexts. Effective interoperability and adequate collaboration in DM have the potential to spare the human life and to control the economic burden. For those reasons, it’s becoming important to find a way for systems and organizations that exploit, at the same time, the technological interoperability and team’s interoperability.

This study aims to provide an overview of the multi-organizational problems and solutions reflecting on achieving interoperability in multi-organizational DM.

Methods:

The article is structured as a scoping review based on the Joanna Briggs Institute’s (JBI) methodology for scoping reviews. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist was used to report the results. The selected papers were assessed using the Critical Appraisal Skills Program (CASP) checklists to screen their methodological quality.

The scoping review was conducted systematically searching the databases PubMed, Google Scholar, and Web of Science. The search algorithm was developed using the three key concepts “interoperability; multi-organizational; disaster medicine” translated into different possible search and Medical Subject Headings (MeSH) terms. Studies of all research design types were considered.

Discussion:

The included literature is reporting experiences on interoperability and how it has been applied to health care systems and organizations interacting during a disaster event. Twelve articles were included. Specific problems and solutions were identified regarding the technological and personnel interoperability, such as ineffective integration, technical problems, lack of an interoperability language, and data filtering network. The suggested approach might involve a focus on both the technological as well the human and personnel interoperability with the aim to create a culture of interoperability through compatible technological solutions and joint trainings.

Conclusions:

This study identified two main approaches during disasters: technology versus personnel interoperability. The suggested approach is to develop a hybrid culture of interoperability through compatible technological solutions combined to joint and multi-disciplinary trainings to achieve the development of a common language.

Further research will need a solution-focused approach on the culture and language of interoperability as thematic gathering training, socio-technical networks, and policies/procedural guidelines.
The use of exemplars differs between native and non-native listening
Authors: Nijveld Annika , ten Bosch Louis , Ernestus Mirjam
Published: April 2022

This study compares the role of exemplars in native and non-native listening. Two English identity priming experiments were conducted with native English, Dutch non-native, and Spanish non-native listeners. In Experiment 1, primes and targets were spoken in the same or a different voice. Only the native listeners showed exemplar effects. In Experiment 2, primes and targets had the same or a different degree of vowel reduction. The Dutch, but not the Spanish, listeners were familiar with this reduction pattern from their L1 phonology. In this experiment, exemplar effects only arose for the Spanish listeners. We propose that in these lexical decision experiments the use of exemplars is co-determined by listeners’ available processing resources, which is modulated by the familiarity with the variation type from their L1 phonology. The use of exemplars differs between native and non-native listening, suggesting qualitative differences between native and non-native speech comprehension processes.
Digital Engagement and Academic Functioning
Authors: Hietajärvi Lauri , Maksniemi Erika , Salmela-Aro Katariina
Published: April 2022

Abstract. Since the turn of the millennium, the digital revolution has opened a new layer of opportunities for adolescents to participate, create and learn. Simultaneously there has been growth in both debate and worries regarding how the intensive engagement with digital media affects students’ academic performance, engagement, and school-related well-being, that is, academic functioning. Students’ continuously evolving digital practices are not always in congruence with the more traditional ways of schoolwork. Students flourish and fulfill their potential when the informal and formal practices of learning reach congruence, but when this is not the case, frictions can emerge. Spending time with digital media can provide new avenues for learning and development, but it can equally well divert young people from their studies or increase the daily demands. In this narrative review, we address these continuities and discontinuities between engagement with digital media and academic functioning for school-aged children and young people, focusing on meta-analyses, reviews, and key studies. Following the examination of the current literature, we conclude that, in general, the field of “digital media effects” needs to move beyond screen time and utilize the research on the students’ multidimensional socio-digital engagement already conducted. Second, we conclude that the average effects of digital engagement on academic functioning are negligibly small but heterogeneous, further corroborating the claim to examine the qualitative differences in students’ digital engagement, the individual differences between students, as well as the contextual interplay.
A New Thunderstorm Identification Algorithm Based on Total Lightning Activity
Authors: Huang Yijun , Fan Yadong , Cai Li , Cheng Si , Wang Jianguo
Published: April 2022

This paper introduces a new thunderstorm identification algorithm called combinatorial 8‐connectivity method based on total lightning activity as observed by the Foshan total lightning location system. The influence of spatio‐temporal parameters on the outcome is presented. The evaluation method contains four criteria: the fitting area of lightning clusters, the area proportion of lightning clusters, the number of lightning clusters and the utilization rate of lightning events. It is found that the fitting area adopting grid cells with size 0.02°–0.05° remains constant around 4, 9, 16 and 25 times those using grid cells of 0.01° in size, respectively. The evaluation criteria change by less than 0.61 km2/min in area, less than 0.43%/min in area proportion, less than 1/min in number and less than 2.8% in utilization rate using 0.01° grid cell when the duration of time interval exceeds 6 min and the spatial gap between grid cells with lightning events is more than 2 gaps. Then, the evaluation results of the combined 8‐connectivity method are compared with the results of the connected‐component labeling method (8, 24, 48, 80 and 120‐connectivity method), and it is found that the performance of combined 8‐connectivity method is better to outline lightning cluster. The two methods have been applied to case analysis on 15 May 2014.
Propagating Seismic Waves in VTI Attenuating Media Using Fractional Viscoelastic Wave Equation
Authors: Wang Ning , Xing Guangchi , Zhu Tieyuan , Zhou Hui , Shi Ying
Published: April 2022

Seismic velocity and attenuation anisotropy are ubiquitous in the crust and upper mantle, significantly modulating the characteristics of seismic wave propagation in the Earth's interior. Accurate seismic wave modeling of velocity and attenuation anisotropy is essential for the understanding of wave propagation in the Earth's interior as well as constructing global and region‐scale seismic full waveform tomography. Here, we derive a decoupled fractional Laplacian (DFL) viscoelastic wave equation to characterize the Earth's frequency‐independent Q behavior in the vertical transversely isotropic (VTI) media. We verify the accuracy of the proposed viscoelastic wave equation by 2D synthetic examples; to show its applicability in crustal‐scale seismic modeling, we present an example of 3D seismic wave propagation in the realistic Salton Trough model. Through extensive numerical tests, we conclude that the proposed viscoelastic wave equation is superior in four aspects. First, the viscoelastic wave equation takes VTI anisotropy of both velocity and attenuation into account and can describe the strong direction‐dependent attenuation. Second, our derivation contains spatially independent Laplacians, and thus the proposed wave equation enjoys higher simulation accuracy for heterogeneous Q media. Third, the new viscoelastic wave equation can decouple the amplitude decay and the phase distortion, which is appealing for improving the resolution in seismic imaging and inversion. Lastly, compared to viscoelastic wave equations with time‐fractional operators, our scheme has higher computational efficiency by avoiding substantial wavefield storage.
Craton Formation in Early Earth Mantle Convection Regimes
Authors: Capitanio Fabio A. , Nebel Oliver , Moyen Jean‐François , Cawood Peter A.
Published: April 2022

How the geological record of cratons reconciles with the tectonic environments in which they formed has remained debated. We use 2D Cartesian geometry numerical models of mantle convection varying temperatures from present day to Archaean‐inferred values, to address the formation of cratons, accounting for melt depletion‐dependent rheological stiffening. For mantle temperatures comparable to present day, melting is negligible and the convective regime depends on the strength of the thermal lithosphere. For mantle potential temperatures higher than present day, high depletion degree and large depleted mantle volumes are formed at low lithospheric strength and high surface mobility, whereas these are negligible beneath a poorly mobile lithosphere. When compared to the models, the record of tectonics and large volumes of high‐degree depleted mantle in Archaean cratons is best explained by a lithosphere initially prone to yielding and mobility. At high mobility, large depletion favors the progressive differentiation of the thermochemical lithosphere, which stiffens and thickens with increasing mantle temperatures. The ensuing reduced heat flow atop a hotter mantle is in agreement with the inferred Archaean thermal evolution, and may rule out the viability of a stagnant lid for the early Earth. Large‐scale depletion stiffening resists plate margin formation and this wanes as heat production decreases, thus may hold the key for the establishment of plate tectonics during secular cooling.

The tropical Pacific and Indian Oceans are connected via a complex system of currents known as the Indonesian Throughflow (ITF). More than 30% of the variability in the ITF is linked to the seasonal cycle, influenced by the Monsoon winds. Despite previous efforts, a detailed knowledge of the ITF response to the components of the seasonal forcing is still lacking. Here, we describe the seasonal cycle of the ITF based on new observations of velocity and properties in Timor Passage, satellite altimetry and a high‐resolution regional model. These new observations reveal a complex mean and seasonally varying flow field. The amplitude of the seasonal cycle in volume transport is approximately 6 Sv. The timing of the seasonal cycle, with semi‐annual maxima (minima) in May and December (February and September), is controlled by the flow below 600 m associated with semi‐annual Kelvin waves. The transport of thermocline waters (<300 m) is less variable than the deep flow but larger in magnitude. This top layer is modulated remotely by cycles of divergence in the Banda Sea, and locally through Ekman transport, coastal upwelling, and non‐linearities of the flow. The latter manifests through the formation of eddies that reduce the throughflow during the Southeast Monsoon, when is expected to be maximum. While the reduction in transport associated with the eddies is small, its impact on heat transport is large. These non‐linear dynamics develop over small scales (<10 km), and without high enough resolution, both observations and models will fail to capture them adequately.

Iron mineral transformations occurring in hydrocarbon‐contaminated sites are linked to the biodegradation of the hydrocarbons. At a hydrocarbon‐contaminated site near Bemidji, Minnesota, USA, measurements of magnetic susceptibility (MS) are useful for monitoring the natural attenuation of hydrocarbons related to iron cycling. However, a transient MS, previously observed at the site, remains poorly understood and the iron mineral phases acting as reactants and products associated with this MS perturbation remain largely unknown. To address these unknowns, we acquired mineral magnetism measurements, including hysteresis loops, backfield curves, and isothermal remanent magnetizations on sediment core samples retrieved from the site and magnetite‐filled mineral packets installed within the aquifer. Our data show that the core samples and magnetite packs display decreasing magnetization with time and that this loss in magnetization is accompanied by increasing bulk coercivity consistent with decreased average grain size and/or partial oxidation. Low‐temperature magnetometry on all samples displayed behavior consistent with magnetite, but samples within the plume also show evidence of maghemitization. This interpretation is supported by the occurrence of shrinkage cracks on the surface of the grains imaged via scanning electron microscopy. Magnetite transformation to maghemite typically occurs under oxic conditions, here, we propose that maghemitization occurs within the anoxic portions of the plume via microbially mediated anaerobic oxidation. Mineral dissolution also occurs within the plume. Microorganisms capable of such anaerobic oxidation have been identified within other areas at the Bemidji site, but additional microbiological studies are needed to link specific anaerobic iron oxidizers with this loss of magnetization.
Root Foraging Alters Global Patterns of Ecosystem Legacy From Climate Perturbations

The response of terrestrial ecosystems to climate perturbations typically persist longer than the timescale of the forcing, a phenomenon broadly referred to as legacy. Understanding the strength of legacy is critical for predicting ecosystem sensitivity to climate extremes and the extent that persistent changes in surface‐atmosphere exchange might feedback onto climate. The cause of ecosystem legacy has been associated with myriad factors such as changes in aboveground biomass, however, few studies have tested how changes in the depth distribution of fine roots in response to perturbation might alter an ecosystem's recovery time. We explore this question using an Earth System Model that includes a dynamic root module where vegetation can forage for water and nutrients by altering their root profiles. The global simulations presented here show that in response to water stress events most ecosystems deepen their root profiles. In semi‐arid ecosystems, this response expedites recovery (i.e., less legacy) relative to simulations without dynamics roots because access to deeper water pools after the initial event remains favorable. In wetter ecosystems, the development of deeper root profiles slows down the recovery timescale (i.e., more legacy) because the deeper root profile reduces access to nutrients and is thus unfavorable. The simulations show that while the inclusion of dynamic roots might only minimally affect global patterns of Gross Primary Productivity and Evapotranspiration, the shift in root profile alters the timescale of recovery. Studies interested in the sustained response of land surfaces fluxes to climate disturbances should consider models that include dynamic root capability.

The timing of transition between the contractional and extensional regimes along the Pyrenean range remains debated. Compared to its central and western parts, the eastern part of the chain was significantly affected by extensional tectonics mostly related to the opening of the Gulf of Lion. The Têt normal fault is the best example of this tectonic activity, with topographic reliefs above 2,000 m in its footwall. In this study, we synthetized previous thermochronological data and performed new (U‐Th)/He and fission track dating in the Eastern Pyrenean massifs. Output apparent exhumation rate and thermal modeling in the hanging wall of the Têt fault highlight a rapid exhumation (0.48 km/Ma) and cooling (∼30°C/Ma) phase between 38 and 35 Ma, followed by slower exhumation/cooling afterward. In the footwall, cooling subsequently propagated westward along the fault during Priabonian (35–32 Ma), upper Oligocene and lower Miocene (26–19 Ma), and Serravallian‐Tortonian times (12–9 Ma). These data and modeling outcomes suggest that the exhumation of the Têt fault hanging wall related to southward thrusting ended at 35 Ma, and was followed by different extensional stages, with a propagation of the deformation toward the West during the upper Miocene. We propose that the onset of extension in the Eastern Pyrenees occurred during the late Priabonian period, contemporaneously with the large‐scale rifting episode recorded in Western Europe. After this event, the Têt fault activity and the westward propagation of the deformation appear mainly controlled by the opening of the Gulf of Lion.
Local Time Variations of the Equatorial Electrojet in Simultaneous Response to Subauroral Polarization Streams During Quiet Time

Published: April 2022

Based on 1‐year equatorial electrojet (EEJ) measurements from Swarm, and ion velocity from the Defense Meteorological Satellite Program, this study first examines the simultaneous effects of the subauroral polarization streams (SAPS) on EEJ during quiet time. The changes in EEJ (ΔEEJ) vary significantly with local time. ΔEEJ flows westward at dawn and is gradually enhanced to eastward at dusk. The eastward ΔEEJ at post‐noon might be driven indirectly by the upward electric field associated with SAPS electric field at SAPS channel, whereas ΔEEJ at pre‐noon might be directly attributed to the penetrating SAPS‐related polarization electric field. Under stronger geomagnetic forcing, a stronger intensity of westward ΔEEJ at dawn and noon is produced, whereas a stronger eastward ΔEEJ at dusk is generated because of a faster SAPS velocity.
