AbstractHatchery production and fisheries stocking is a widespread and high profile management practice because it allows recreational fisheries to continue in threatened species. Human-mediated transfer of fish across the geographic boundaries of intraspecies lineages or closely related species can cause introgression and occasionally outbreeding depression. Hybridization can be difficult to detect due to limited morphological differences among close lineages and the relatively low power of traditional genetic datasets. Here we showcase the use of genomic techniques to detect admixture of the economically important and threatened golden perch (Macquaria ambigua) in the Murray-Darling Basin, southeast Australia. We detected admixture through a genome-wide dataset of 6,862 single nucleotide polymorphisms (SNPs) across 174 Murray-Darling sourced fish and 15 fish from each of two neighbouring basins: the Lake Eyre and Fitzroy basins. Individuals with partial ancestry from both neighboring basins were detected using genomics throughout the Murray-Darling, suggesting the release of individuals and introgression into the Murray-Darling Basin. Importantly, a traditional microsatellite dataset was unreliable for identifying admixed individuals. The SNP-detected admixed individuals were also found in Murray-Darling impoundments, where fish are solely sourced from government-managed hatcheries, suggesting that some broodstock in hatcheries might have non-endemic ancestry. Stocking programs for golden perch release over one million fingerlings each year, and so could impact the genetic variation in the wild. We advocate for using genomics to check the ancestry of broodstock and for increasing collaboration between managers and academics—as done here—to better integrate the power of genomics into biodiversity management and conservation.
The Resilience of FDI to Natural Disasters Through Industrial Linkages
Authors: Kato Hayato , Okubo Toshihiro 
Published: April 2022

AbstractWhen do multinationals show resilience during natural disasters? To answer this, we develop a simple model in which foreign multinationals and local firms in the host country are interacted through input-output linkages. When natural disasters seriously hit local firms and thus increase the cost of sourcing local intermediate inputs, most multinationals may leave the host country. However, they are likely to stay if they are tightly linked with local suppliers and face low trade costs of importing foreign intermediates. We further provide a number of extensions of the basic model to incorporate, for example, multinationals with heterogeneous productivity and disaster reconstruction.

Abstract
Teachers’ burnout has severe consequences for themselves and their students. The identification of factors related to burnout can provide valuable information about the relevance of interindividual differences. Beyond work-related factors, burnout is assumed to be affected by individuals’ personality traits, and several empirical studies already exist that have investigated this association in teachers. However, a comprehensive meta-analytical examination is missing so far. The current meta-analysis, including 18 primary studies with 19 samples (total N = 4,724), aimed to examine the relation between burnout dimensions (emotional exhaustion, depersonalization, and reduced personal accomplishment) and the Big Five personality traits (neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness) in teachers. In addition, moderating effects of teachers’ professional level were investigated. In line with our expectations, neuroticism was positively related to all three burnout dimensions, with medium-sized effects found for emotional exhaustion and depersonalization and a small effect size found for reduced personal accomplishment. The other significant associations between personality traits and burnout dimensions were negative. Apart from a nonsignificant association between emotional exhaustion and openness, all associations were rated as small to medium. The moderator analyses did not show any support for moderating effects of teachers’ professional level concerning the associations between burnout dimensions and personality traits.
International Predictors of Contract Cheating in Higher Education
Authors: Awdry R. , Ives B. 
Published: April 2022

AbstractPrevalence of contract cheating and outsourcing through organised methods has received interest in research studies aiming to determine the most suitable strategies to reduce the problem. Few studies have presented an international approach or tested which variables could be correlated with contract cheating. As a result, strategies to reduce contract cheating may be founded on data from other countries, or demographics/situations which may not align to variables most strongly connected to engagement in outsourcing. This paper presents the results of a series of statistical analyses aimed at testing which variables were found to be predictors of students’ self-reported formal outsourcing behaviours. The data are derived from an international research study conducted in 22 languages, with higher education students (from Europe, the Americas and Australasia. Analyses found that country and discipline of study as well as the rate at which respondents n = 7806) believed other students to be cheating, were positively correlated to their cheating behaviours. Demographic variables did not show strong statistical significance to predicting contract cheating.
Topology optimization using the discrete element method. Part 1: Methodology, validation, and geometric nonlinearity
Authors: O’Shaughnessy Connor , Masoero Enrico , Gosling Peter D. 
Published: April 2022

AbstractStructural Topology optimization is attracting increasing attention as a complement to additive manufacturing techniques. The optimization algorithms usually employ continuum-based Finite Element analyses, but some important materials and processes are better described by discrete models, for example granular materials, powder-based 3D printing, or structural collapse. To address these systems, we adapt the established framework of SIMP Topology optimization to address a system modelled with the Discrete Element Method. We consider a typical problem of stiffness maximization for which we define objective function and related sensitivity for the Discrete Element framework. The method is validated for simply supported beams discretized as interacting particles, whose predicted optimum solutions match those from a classical continuum-based algorithm. A parametric study then highlights the effects of mesh dependence and filtering. An advantage of the Discrete Element Method is that geometric nonlinearity is captured without additional complexity; this is illustrated when changing the beam supports from rollers to hinges, which indeed generates different optimum structures. The proposed Discrete Element Topology Optimization method enables future incorporation of nonlinear interactions, as well as discontinuous processes such as during fracture or collapse.

AbstractGrain size is one of the major traits that determine rice grain yield and quality. The GS3 gene is the first major quantitative trait locus (QTL) that was identified in regulating rice grain length and weight. It was reported that the gs3 allele with a mutation in the organ size regulation (OSR) domain of the GS3 protein produced longer grains. In this study, we used the CRISPR/Cas9 gene editing technology to introduce an edited gs3 allele into our indica maintainer line, Mei1B, to enhance its grain yield and quality. Through molecular analysis and sequencing, a homologous edited-gs3 mutant line without any transgene was obtained in the T1 generation and was named Mei2B. A superior male sterile line Mei2A was generated by backcrossing the cytoplasmic male sterile (CMS) line Mei1A with Mei2B. Mei2B had a higher grain quality and yield compared to its wild-type Mei1B. Its grain length increased by 7.9%, its length/width ratio increased from 3.89 to 4.19, TGW increased by 6.7%, and grain yield per plant increased by 14.9%. In addition, genetic improvement of other quality traits including brown rice length (6.83 mm), brown rice grain length/width ratio (3.61), matched the appearance standards set for traditional Simiao (silk seedling) type cultivars. Two restorer lines were outcrossed to both Mei1A and Mei2A to produce hybrid rice. Compared to two hybrids of Mei1A, the hybrids of Mei2A had longer grains, higher length/width ratio, TGW, and yield per plant. In addition, the hybrids of Mei2A showed a better grain appearance including better translucency, a lower chalky rice rate, and degree of chalkiness than the hybrids of Mei1A. These results demonstrated that the introduction of an elite gs3 allele into Mei1A via CRISPR/Cas9 gene editing technology led to significant genetic improvement of the rice grain. The resultant CMS line Mei2A(gs3) displayed much higher grain quality and yield than the original Mei1A. Therefore, our study demonstrated that the targeted genetic improvement via gene editing technology can enhance rice breeding, especially the breeding of three-line hybrid rice.
Exploring polarisation in economic hardship among Italian macro-regions
Authors: Ruiu Gabriele 
Published: April 2022

AbstractEconomic polarisation in a society may be defined as the creation of groups with strong within-group identity and significant distance from other groups, where the distance is measured in terms of income. The literature on social conflicts considers polarisation a menace to political stability. Italy is characterised by a wide economic divide between the north and the south. This paper investigates the polarisation among Italian macro-regions in 2004–2016. We find that polarisation is low across the country. Paradoxically, the large inequalities inside each region, by hampering the formation of group identity, have hindered the increase in polarisation.
Schedulability analysis of dynamic priority real-time systems with contention

Published: April 2022

AbstractIn multicore scheduling of hard real-time systems, there is a significant source of unpredictability due to the interference caused by the sharing of hardware resources. This paper deals with the schedulability analysis of multicore systems where the interference caused by the sharing of hardware resources is taken into account. We rely on a task model where this interference is integrated in a general way, without depending on a specific type of hardware resource. There are similar approaches but they consider fixed priorities. The schedulability analysis is provided for dynamic priorities assuming constrained deadlines and based on the demand bound function. We propose two techniques, one more pessimistic than the other but with a lower computational cost. We evaluate the two proposals for different task allocators in terms of the increased estimated utilization. The results show that both bounds are valid for ensuring schedulability although, as expected, one is tighter than the other. The evaluation also serves to compare allocators to see which one produces less interference.

AbstractThe emerging Multi-Processor System-on-Chip (MPSoC) technology, which combines heterogeneous computing with the high performance of field programmable gate arrays (FPGA), is a promising platform for a large number of applications, including wireless communications and vehicular technology. In this specific application context, when multiple-input multiple-output (MIMO) scenarios are considered, the system usually has to manage a large number of communication links among sensors and antennas involving different vehicles and users. Millimeter wave (mmWave) communications are one of the key technology enablers toward achieving high data rates in beyond 5G systems (B5G). Communication at these frequency bands usually involves the use of large antenna arrays, often requiring high computational resources. One of the candidate platforms able to manage a huge number of communications is the Xilinx Zynq UltraScale+ EG Heterogeneous MPSoC, which is composed of a dual-core Cortex-R5, a quad-core ARM Cortex-A53, a graphics processing unit (GPU) and a high-end FPGA. This work analyzes the computational performance that requires a recent mmWave MIMO channel estimation algorithm in a platform of this kind. As a first approach, we will focus our work on the performance that can be achieved via the quad-core ARM Cortex-A53. To this end, we will use the libraries for numerical algebra (BLAS and LAPACK). The results show that our reference implementation is able to manage a large MIMO communication system with 256 antennas without exhausting platform resources.
Computational modeling in philosophy: introduction to a topical collection
Authors: Scheller Simon , Merdes Christoph , Hartmann Stephan 
Published: April 2022

AbstractComputational modeling should play a central role in philosophy. In this introduction to our topical collection, we propose a small topology of computational modeling in philosophy in general, and show how the various contributions to our topical collection fit into this overall picture. On this basis, we describe some of the ways in which computational models from other disciplines have found their way into philosophy, and how the principles one found here still underlie current trends in the field. Moreover, we argue that philosophers contribute to computational modeling not only by building their own models, but also by thinking about the various applications of the method in philosophy and the sciences. In this context, we note that models in philosophy are usually simple, while models in the sciences are often more complex and empirically grounded. Bridging certain methodological gaps that arise from this discrepancy may prove to be challenging and fruitful for the further development of computational modeling in philosophy and beyond.

Published: April 2022

Introduction Many medical schools engage students in health system improvement (HSI) efforts. Evaluation of these efforts often focuses on students’ learning outcomes and rarely considers the impact on health systems, despite the significant commitment health systems make to these efforts. Our study identified and evaluated system-level outcomes of pre-clerkship medical students’ engagement in HSI efforts. Methods We used an instrumental case study approach to examine the effects of pre-clerkship medical students’ engagement in HSI projects as part of a 15-month experiential curriculum. We extracted data from 53 project summaries and posters completed during the 2017–18 academic year and follow-up survey data collected in May 2019 from physician coaches and health system professionals who mentored students, contributed to these projects, and worked in the clinical microsystems where the projects occurred. Results We identified three categories and ten indicators of health system outcomes relevant to medical student engagement in HSI. Using these indicators, our evaluation found multiple benefits to the microsystems in which projects occurred. These included achievement of project aims, perceived immediate and sustained project impact on the health system, and development and implementation of projects with aims that aligned with national and health system priorities. Conclusion Evaluation of HSI curricula needs to include effects on health systems so that program design can optimize the experience for all involved. Our study offers a framework others can use to evaluate system-level effects of project-based HSI curricula and shows several ways in which students’ engagement can add value to health systems.
Advances in Atomic Layer Deposition

Published: April 2022

AbstractAtomic layer deposition (ALD) is a thin-film fabrication technique that has great potential in nanofabrication. Based on its self-limiting surface reactions, ALD has excellent conformality, sub-nanometer thickness control, and good process compatibility. These merits promote the industrial and research applications of ALD in various fields. This article provides an introduction to ALD and highlights its applications in semiconductors, pan-semiconductors, environment and energy, and other fields. The applications of ALD in the key nodes of integrated circuits are initially demonstrated, and the area-selective ALD technique is discussed as a bottom-up method for self-aligned nanomanufacturing. Emerging applications of ALD are illustrated in the fabrication of passivation layers, functional surface layers, and buffer layers, which have shown the development trend of ALD in miniaturization and diversification. ALD is an enabling technique for atomic and close-to-atomic scale manufacturing (ACSM) of materials, structures, devices, and systems in versatile applications. The use of theory calculation, multiscale simulation, and more novel methods would steer ALD into further evolution, which makes it possible to cater to the demand of ACSM.

AbstractIntroduction:Racial disparities in colorectal cancer (CRC) can be addressed through increased adherence to screening guidelines. In real-life encounters, patients may be more willing to follow screening recommendations delivered by a race concordant clinician. The growth of telehealth to deliver care provides an opportunity to explore whether these effects translate to a virtual setting. The primary purpose of this pilot study is to explore the relationships between virtual clinician (VC) characteristics and CRC screening intentions after engagement with a telehealth intervention leveraging technology to deliver tailored CRC prevention messaging.Methods:Using a posttest-only design with three factors (VC race-matching, VC gender, intervention type), participants (N= 2267) were randomised to one of eight intervention treatments. Participants self-reported perceptions and behavioral intentions.Results:The benefits of matching participants with a racially similar VC trended positive but did not reach statistical significance. Specifically, race-matching positively influenced screening intentions for Black participants but not for Whites (b= 0.29,p= 0.10). Importantly, perceptions of credibility, attractiveness, and message relevance significantly influenced screening intentions and the relationship with race-matching.Conclusions:To reduce racial CRC screening disparities, investments are needed to identify patient-focused interventions to address structural barriers to screening. This study suggests that telehealth interventions that match Black patients with a Black VC can enhance perceptions of credibility and message relevance, which may then improve screening intentions. Future research is needed to examine how to increase VC credibility and attractiveness, as well as message relevance without race-matching.

ABSTRACTIn the frame of the IAEA-CRP (Coordinated Research Projects): Enhancing Nuclear Analytical Techniques to Meet the Needs of Forensic Sciences, an intercomparison exercise was organized between three AMS laboratories. Aim of the program is to promote the use of nuclear and accelerator-based techniques in routine forensics practice. In this view, one of the key points is the assessment of the precision and accuracy levels achievable on material of forensic interest. We review the general structure and status of the project, with emphasis on results obtained in the analysis of wines of different grape varieties and grounded coffee beans from different locations such as Brazil, Spain, and Italy. The three laboratories processed the samples according to different chemical protocols and performed the 14C measurements using different systems: MICADAS in Zurich and Debrecen and a HVEE 4130HC 3 MV Tandetron in Lecce. Within the quoted uncertainty, the results showed good reproducibility, indicating that uncertainty level of the order of 0.3% are achieved by AMS on a single sample while multiple sample analyses results in precision down to 0.1–0.2%. The measured 14C concentrations on coffee and wine samples resulted to be consistent with atmospheric 14C levels in the growing years.
Neoplatonism and the Pax Mongolica in the making of ṣulḥ-i kull. A view from Akbar's millennial history
Authors: Gommans Jos , Huseini Said Reza 
Published: April 2022

AbstractThis article argues that ṣulḥ-i kull (peace for all) as a specific term was introduced in the 1590s by a small group of avant-garde Neoplatonists who worked at the court of the Mughal emperor Akbar. It was only in the following century that ṣulḥ-i kull developed into the ethos that became the ideological mainstay of Mughal rule both internally, for its administrative elites, and externally, vis-à-vis their main rivals: the Uzbeks in Central Asia and the Safavids in Iran. The early stages in the making of this ideology can be followed in some detail by studying Akbar's neglected millennial history, the Tarikh-i Alfi. In fact, this vast Mughal world history demonstrates that apart from Neoplatonic akhlāq, there was another important building block that so far has been missing altogether in the making of ṣulḥ-i kull, that is, the practical model of the Pax Mongolica, as established under Chinggis Khan, the most famous of Mughal ancestors. Most crucially, it is in the Tarikh-i Alfi that we find the legacies of Persianate akhlāq and Mongol yasa (law) married to each other. In fact, it was through akhlāq that the peace of the Mongols became the Mughal peace for all.
