Causal models, creativity, and diversity
Authors: Baciu Dan C. 
Published: April 2023

AbstractCausal models find application in almost all areas of science, and they often support the development of theories that are straightforward and testable. Yet scientists also observe things that surprise them. Fascinated by such observations, they learn to admire the playful aspects of life, as well as its creativity and diversity. Under these circumstances, a compelling question arises: Can causal models explain life’s creativity and diversity? Some life scientists say yes. However, other humanities scholars cast doubt, positing that they reached the end of theory. Here, I build on common empirical observations as well as long-accumulated modeling experience, and I develop a unified framework for causal modeling. The framework gives special attention to life’s creativity and diversity, and it applies to all sciences including physics, biology, the sciences of the city, and the humanities.

AbstractInstitutional investors are very important for keeping shareholder value high by reducing agency conflict and promoting good governance. Recent governance scandals have placed Malaysia on the global stage, jeopardising the publicly listed companies (PLCs) reputation and calling into question the effectiveness of the country’s corporate governance mechanism. The study aimed to examine the level of agency conflict in Malaysian PLCs and the roles of institutional investors in mitigating agency issues. At the same time, we are exploring unclear institutional investors level of activism in Malaysia and evaluating which roles are considered powerful among institutional investors. The findings demonstrated that institutional investors significantly mitigate agency conflict, with monitoring and dialogue engagement as the most influential roles. Conclusively, the discovery reinstated Type 1 agency conflict (principal-agent) among important issues for corporate governance in Malaysia. The study meets the gaps of prior research in the Malaysian context of agency conflict. It offers a novelty on agency conflict examination in Malaysia as well as exploring institutional investors’ roles and recommending an approach that can be taken to strengthen the governance mechanism among PLCs in Malaysia. The present study advises institutional investors to play aggressive roles in managing agency issues, and relevant bodies need to enhance awareness of agency issues.

Objectives There is limited evidence regarding the effectiveness of transition care programs (TCP) in improving health-related outcomes and discharge destination for older adults. This study aimed to (i) identify changes in health-related outcomes in older adults undergoing a facility-based TCP between admission and discharge; and (ii) compare health-related outcomes between participants discharged home and those discharged to permanent residential care. Method A prospective, observational study was conducted with older adults aged ≥60 years who participated in a facility-based TCP that provided short-term rehabilitation including mobility training, group exercise and cognitive activities. Physical, cognitive and social outcomes were measured at admission and discharge. Data were analysed using linear mixed modelling. Results Of the 41 participants (mean age 80.1 (±8.9) years), 26 (63.4%) were discharged home compared with 14 (34.2%) to residential care. Participants showed statistically significantly improvement in performance of activities of daily living (ADL), mobility and health-related quality of life, with a statistically and clinically significant decline in performance of instrumental ADL. Participants discharged home had statistically and clinically significant greater improvement in mobility compared with those discharged to residential care (de Morton mobility index: home, 13.6 (95% CI: 9.8, 17.4) vs residential, 6.9 (95% CI: 1.7, 12.0), Pinteraction = 0.04) and statistically and clinically significant less decline in instrumental ADL (Lawton’s scale: home, −0.8 (95% CI: −1.3, −0.2) vs residential, −2.1 (95% CI: −2.9, −1.4), Pinteraction = 0.002). Conclusion Older adults participating in a facility-based TCP had improvements in physical, cognitive and social functional abilities. However, those who returned home still had residual mobility deficits and decreased performance of instrumental ADL when compared with normative community level recommendations, which could impact on longer term community living. Further research investigating which program service components could be modified to further improve rehabilitation outcomes could benefit older adults in returning and remaining at home.
Recruitment of Melaleuca quinquenervia (Myrtaceae) in the fringing forests of the Myall Lakes, NSW, Australia
Authors: Baumann Anne , Hewitt Alison 
Published: April 2023

Context Melaleuca quinquenervia is a widespread, keystone species of eastern Australian coastal forested wetlands. Populations of M. quinquenervia in the fringes of Myall Lakes, New South Wales, Australia exhibit low numbers of juveniles, infrequent recruitment and a dominance of mature individuals, raising concerns about stand replacement from conservation managers. In contrast, M. quinquenervia often recruits in large numbers and is highly invasive in wetlands around the world. Aims To explore factors that limit recruitment of M. quinquenervia within its native range. Methods Field deployed seed traps; soil-core sampling; a burial longevity trial and depth of emergence experiment; laboratory temperature, salinity and light germination experiments; a transplantation experiment; monitoring of field germination; and a litter/leachate experiment. Key results Low seed viability (5–26%) is offset by high canopy seed loads (250 000 to 120 million seeds per tree) released continuously throughout the year with a peak fall in summer (2000 to 5000 viable seeds per m2 per month), coinciding with optimal germination temperatures. Seedling emergence is reduced below 5 mm soil depth, there is a very low soil seedbank reserve, and germination is light-dependant. M. quinquenervia exhibited reduced germination percentage and rate as well as reduced survival of seedlings at salinities higher than 15 dS m−1 EC (electrical conductivity). The most favourable sites for seedling establishment are permanently moist with low salinity, protected from wave action via sedge vegetation, and sheltered from prevailing winds. There is an inhibitory effect of Casuarina leachate on germination. Conclusions Germination in the field is episodic, and tied to specific environmental conditions. Highest losses occur at the seedling establishment phase. Implications Future research avenues and management recommendations are provided.

Published: April 2023

Context Many mycorrhizal fungi are vital to nutrient acquisition in plant communities, and some taxa are reliant on animal-mediated dispersal. The majority of animals that disperse spores are relatively small and have short-distance movement patterns, but carnivores – and especially apex predators – eat many of these small mycophagists and then move greater distances. No studies to date have assessed the ecosystem services carnivores provide through long-distance spore dispersal. Aims In this study, we aimed to investigate whether Australia’s free-ranging dogs (Canis familiaris), including dingoes, act as long-distance spore dispersers by predating smaller mycophagous animals and then secondarily dispersing the fungi consumed by these prey species. Methods To answer this question, we collected dingo scats along 40 km of transects in eastern Australia and analysed the scats to determine the presence of fungal spores and prey animals. Using telemetry and passage rate data, we then developed a movement model to predict the spore dispersal potential of dingoes. Key results We found 16 species of mammalian prey to be eaten by dingoes, and those dingo scats contained spores of 14 genera of mycorrhizal fungi. These fungi were more likely to appear in the scats of dingoes if primary mycophagist prey mammals had been consumed. Our model predicted dingo median spore dispersal distance to be 2050 m and maximum dispersal potential to be 10 700 m. Conclusions Our study indicates that dingoes are providing a previously overlooked ecosystem service through the long-distance dispersal of mycorrhizal fungi. Many of the fungi found in this study form hypogeous (underground) fruiting bodies that are unable to independently spread spores via wind. Because dingoes move over larger areas than their prey, they are especially important to these ecosystem functions. Implications Our novel approach to studying an overlooked aspect of predator ecology is applicable in most terrestrial ecosystems. Similar modelling approaches could also be employed to understand the dispersal potential of both primary and secondary spore dispersers globally. Because this study highlights an unrecognised ecosystem service provided by dingoes, we hope that it will stimulate research to develop a more comprehensive understanding of other apex predators’ ecosystem functions.
La traducción económico-financiera vista por los profesionales
Authors: Gallego Hernández Daniel 
Published: April 2023

Abstract
This article presents a mapping of economic translation based on the content of book chapters and articles
published by translation professionals, excluding academic publications. Using quantitative and qualitative bibliometric
techniques, we analyze a corpus of 115 publications signed by translators, clients, and other specialists and compare their topics
with those of academics. First, there is a downward trend in the number of publications by professionals, with the 1995–2005
period being the most productive. The results also show that some of the content discussed is not described in depth or ends up
stagnating and differs from that of academics, suggesting that the interests of professionals and academics rarely converge.
Suggestions for future improvement measures related to teaching and research are provided to reduce the gap between the two groups
of authors.
Estonian and Swedish color idioms – shared and unshared
Authors: Oguz Merle , Uusküla Mari 
Published: April 2023

Abstract
Previous research on color idioms has shown that they are often culture-specific, and translating them requires shifting between cognitive frames of reference. However, little research has been carried out on the translation process of such idioms. We investigated how Swedish color idioms were translated into Estonian by professional translators and novices, tracking the components of the translation process, such as time spent on the tasks, resources used, and the importance of context provided. Finally, we detected eight translation strategies used for idiom translation. The strategies used depended on the idiom’s transparency between the source and target language. The conventionality of the idiom seemed to have little impact on the difficulty experienced. Professionals and novices used different approaches to translation which once again confirms the importance of acquired skills and experience. Color idioms can turn out to be false friends. Focusing first and foremost on the idiomaticity of the target language helps. Professionals searched for the target language idiom and used various monolingual resources in the target language while novices searched mainly for source-language idioms and used no monolingual target language web dictionaries.

Abstract
This paper explores the dynamics and electronic validations of a memristive Helmholtz snap oscillator (MHSO), employing it to model a process of pseudo-random number generator (PRNG). The MHSO depicts two lines of Hopf bifurcation is associated with one of the equilibrium domains while the other region of equilibrium points is always unstable. Extreme multistability features, hidden complex attractors, antimonotonicity equilibrium points. Characterizing the stability of the equilibrium domains, period-3-oscillations and chaotic hidden attractors coexisting, chaotic bubbles, and hidden attractors are generated in MHSO for particular values of parameters. Electronic validations of MHSO based on OrCAD-PSpice software and microcontroller reveal that OrCAD-PSpice and microcontroller dynamics agree well with the dynamics achieved by numerical simulations. Lastly, the chaotic characteristics depicted by the MHSO are used to design a process of PRNG. The generated random bits are validated successfully by a standard statistical tool set by the National Institute of Standards and Technology (NIST-800-22).
Superradiant axion clouds around asteroid-mass primordial black holes
Authors: Branco Nuno P. , Ferreira Ricardo Z. , Rosa João G. 
Published: April 2023

Abstract
We analyze the dynamics and observational signatures of axion clouds formed via the superradiant instability around primordial black holes, focusing on the mass range 1014 - 1018 kg where the latter may account for all the dark matter.
We take into account the leading effects of axion self-interactions, showing that, even though these limit the number of axions produced within each cloud,
a large number of superradiant axions become free of the black hole's gravitational potential and accumulate in the intergalactic medium or even in the host galaxy, depending on their escape velocity. This means that primordial black hole dark matter may lead to a sizeable astrophysical population of non-relativistic axions, with masses ranging from 0.1 eV to 1 MeV, depending on the primordial black hole mass and spin.
We then show that if such axions couple to photons their contribution to the galactic and extragalactic background flux, mainly in the X-ray and gamma-ray band of the spectrum, is already beyond current observational limits for a large range of parameters that are, therefore, excluded. We finish by showing the prospects of the Athena X-ray telescope to further probe this co-existence of primordial black holes and axions.

Published: April 2023

Abstract
Collective motion is commonly modeled with static interaction rules between agents. Substantial empirical evidence indicates, however, that animals may adapt their interaction rules depending on a variety of factors and social contexts. Here, we hypothesized that leadership performance is linked to the leader’s responsiveness to the follower’s actions and we predicted that a leader is followed longer if it adapts to the follower’s avoidance movements. We tested this prediction with live guppies that interacted with a biomimetic robotic fish programmed to act as a ‘socially competent’ leader. Fish that were avoiding the robot were approached more carefully in future approaches. In two separate experiments we then asked how the leadership performance of the socially competent robot leader differed to that of a robot leader that either approached all fish in the same, non-responsive, way or one that did change its approach behavior randomly, irrespective of the fish’s actions. We found that (1) behavioral variability itself appears attractive and that socially competent robots are better leaders which (2) require fewer approach attempts to (3) elicit longer average following behavior than non-competent agents. This work provides evidence that social responsiveness to avoidance reactions plays a role in the social dynamics of guppies. We showcase how social responsiveness can be modeled and tested directly embedded in a living animal model using adaptive, interactive robots.
Evaluating the hourly emissions intensity of the US electricity system
Authors: Miller Gregory J , Pease Gailin , Shi Wenbo , Jenn Alan 
Published: April 2023

Abstract
High-quality data for the greenhouse gas and air pollution emissions associated with electricity generation and consumption are increasingly important to enable effective and targeted action to decarbonize the electric grid and to inform research in a range of academic disciplines including environmental economics, lifecycle assessment, and environmental health. To inform the broadest range of use cases, such data should ideally have a high temporal and spatial resolution, be available in as close to real-time as possible, represent the complete power sector, use the highest-quality measured data, have complete historical coverage, and represent both generated and consumed emissions. To date, no published datasets have achieved all of these characteristics. This work is the first to publish a comprehensive, plant-level dataset of hourly-resolution generation, fuel consumption, and direct CO2, NOx, and SO2 emissions for the entire U.S. power sector. This data is published as part of the public and open-source Open Grid Emissions Initiative, which also includes hourly, consumption-based emissions intensities for every grid balancing area in the country. Using insights generated by this new dataset, this paper also interrogates how several of the assumptions implicit in the use of existing power sector emissions datasets may under-count or misrepresent the climate and health impacts of air emissions from the U.S. power sector. We envision the Initiative becoming a central repository of, and hub of activity for addressing open research questions related to power sector emissions data, and the go-to source for high-quality, high-resolution data for future research on grid emissions.

Abstract
Investigating sex as a biological variable is key to determine obesity manifestation and treatment response. Individual neuroimaging modalities have uncovered mechanisms related to obesity and altered ingestive behaviours. However, few, if any, studies have integrated data from multi-modal brain imaging to predict sex-specific brain signatures related to obesity. We used a data-driven approach to investigate how multi-modal MRI and clinical features predict a sex-specific signature of participants with high body mass index (overweight/obese) compared to non-obese body mass index in a sex-specific manner. A total of 78 high body mass index (55 female) and 105 non-obese body mass index (63 female) participants were enrolled in a cross-sectional study. All participants classified as high body mass index had a body mass index greater than 25 kg/m2 and non-obese body mass index had a body mass index between 19 and 20 kg/m2. Multi-modal neuroimaging (morphometry, functional resting-state MRI and diffusion-weighted scan), along with a battery of behavioural and clinical questionnaires were acquired, including measures of mood, early life adversity and altered ingestive behaviours. A Data Integration Analysis for Biomarker discovery using Latent Components was conducted to determine whether clinical features, brain morphometry, functional connectivity and anatomical connectivity could accurately differentiate participants stratified by obesity and sex. The derived models differentiated high body mass index against non-obese body mass index participants, and males with high body mass index against females with high body mass index obtaining balanced accuracies of 77 and 75%, respectively. Sex-specific differences within the cortico-basal-ganglia-thalamic-cortico loop, the choroid plexus-CSF system, salience, sensorimotor and default-mode networks were identified, and were associated with early life adversity, mental health quality and greater somatosensation. Results showed multi-modal brain signatures suggesting sex-specific cortical mechanisms underlying obesity, which fosters clinical implications for tailored obesity interventions based on sex.
How Does Political Tolerance Moderate the Effects of Social Media Use on Political Polarization: A Moderated Mediation Model
Authors: Xia Chuanli , Shen Fei 
Published: April 2023

AbstractThis study proposes a moderated mediation model to understand how social media use influences political polarization through two competing mechanisms and how such mechanisms are conditioned by political tolerance. The model was tested with a survey of 1,200 Hong Kong residents after the prolonged Anti-Extradition Law Amendment Bill movement. We found that social media use was positively correlated with attitudinal and affective polarization. Such polarizing effects were channeled through politically motivated selective avoidance, but there were noticeable depolarizing effects induced by increased network heterogeneity. More importantly, political tolerance could further amplify the depolarizing effects of social media use. In contrast, political tolerance cannot counteract the polarizing effect of social media use channeled through selective avoidance.
In Situ Sputtering From the Micromanipulator to Enable Cryogenic Preparation of Specimens for Atom Probe Tomography by Focused-Ion Beam
Authors: Douglas James O , Conroy Michele , Giuliani Finn , Gault Baptiste 
Published: April 2023

Abstract
Workflows have been developed in the past decade to enable atom probe tomography analysis at cryogenic temperatures. The inability to control the local deposition of the metallic precursor from the gas-injection system (GIS) at cryogenic temperatures makes the preparation of site-specific specimens by using lift-out extremely challenging in the focused-ion beam. Schreiber et al. exploited redeposition to weld the lifted-out sample to a support. Here, we build on their approach to attach the region-of-interest and additionally strengthen the interface with locally sputtered metal from the micromanipulator. Following standard focused-ion beam annular milling, we demonstrate atom probe analysis of Si in both laser pulsing and voltage mode, with comparable analytical performance as a presharpened microtip coupon. Our welding approach is versatile, as various metals could be used for sputtering, and allows similar flexibility as the GIS in principle.
