AbstractThe International VLBI Service for Geodesy and Astrometry (IVS) regularly provides high-quality data to produce Earth Orientation Parameters (EOP), and for the maintenance and realisation of the International Terrestrial and Celestial Reference Frames, ITRF and ICRF. The first iteration of the celestial reference frame (CRF) at radio wavelengths, the ICRF1, was adopted by the International Astronomical Union (IAU) in 1997 to replace the FK5 optical frame. Soon after, the IVS began official operations and in 2009 there was a significant increase in data sufficient to warrant a second iteration of the CRF, ICRF2. The most recent ICRF3, was adopted by the IAU in 2018. However, due to the geographic distribution of observing stations being concentrated in the Northern hemisphere, CRFs are generally weaker in the South due to there being fewer Southern Hemisphere observations. To increase the Southern Hemisphere observations, and the density, precision of the sources, a series of deep South observing sessions was initiated in 1995. This initiative in 2004 became the IVS Celestial Reference Frame Deep South (IVS-CRDS) observing programme. This paper covers the evolution of the CRDS observing programme for the period 1995–2021, details the data products and results, and concludes with a summary of upcoming improvements to this ongoing project.
Is Carbon Risk Priced in the Cross Section of Corporate Bond Returns?
Authors: Duan Tinghua , Li Frank Weikai , Wen Quan 
Published: June 2023

Abstract
This article examines the pricing of a firm’s carbon risk in the corporate bond market. Contrary to the “carbon risk premium” hypothesis, bonds of more carbon-intensive firms earn significantly lower returns. This effect cannot be explained by a comprehensive list of bond characteristics and exposure to known risk factors. Investigating sources of the low carbon alpha, we find the underperformance of bonds issued by carbon-intensive firms cannot be fully explained by divestment from institutional investors. Instead, our evidence is most consistent with investor underreaction to the predictability of carbon intensity for firm cash-flow news, creditworthiness, and environmental incidents.
Quantitative experimental L2 acquisition MALL studies: A critical evaluation of research quality

AbstractWith more than 1,200 publications over the past two decades, experimental mobile-assisted language learning (MALL) studies targeting second/foreign language (L2) acquisition outcomes are certainly not lacking in quantity. Their research quality, on the other hand, has often been brought into question, most notably with regard to the adequacy of their assessment instruments and statistical analyses. Yet limiting the determination of research quality to the evaluation of testing procedures, and the statistical analysis of the results they produce, ignores the critical relevance of the underlying research parameters that generate the results in the first place. A comprehensive evaluation of quantitative experimental L2 acquisition MALL research quality, encompassing design as well as assessment instruments and statistical analysis, thus remains to be undertaken. The present investigation endeavors to do so based on an extensive compilation of 737 MALL studies published between 2000 and 2021. The research quality of these publications is evaluated according to four main parameters: language acquisition moderators, treatment intervention conditions, assessment instruments, and statistical analysis. These are applied according to a modified version of the Checklist for the Rigor of Education-Experiment Designs (CREED), which classifies research design quality into five levels: low, medium-low, medium, medium-high, high. With over three quarters of all studies falling within the low category, the result leaves much to be desired. Since the modified CREED algorithm developed here can equally be applied to studies from their inception, it offers a way forward to improve the research quality of future experimental MALL studies.
Alterations in the expression pattern of some epigenetic-related genes and microRNAs subsequent to oocyte cryopreservation
Authors: Shadmanesh Ali , Nazari Hassan 
Published: June 2023

SummaryMicroRNAs (miRNAs) are small non-encoding RNAs that actively regulate biological and physiological processes, and play an important role in regulating gene expression in all cells, especially in most animal cells, including oocytes and embryos. The expression of miRNAs at the right time and place is crucial for the oocyte’s maturation and the embryo’s subsequent development. Although assisted reproductive techniques (ART) have helped to solve many infertility problems, they cause changes in the expression of miRNA and genes in oocytes and preimplantation embryos, and the effect of these changes on the future of offspring is unknown, and has caused concerns. The relevant genomic alterations commonly imposed on embryos during cryopreservation may have potential epigenetic risks. Understanding the biological functions of miRNAs in frozen maturated oocytes may provide a better understanding of embryonic development and a comparison of fertility conservation in female mammals. With the development of new techniques for genomic evaluation of preimplantation embryos, it has been possible to better understand the effects of ART. The results of various articles have shown that freezing of oocytes and the cryopreservation method are effective for the expression of miRNAs and, in some cases, cause changes in the expression of miRNAs and epigenetic changes in the resulting embryo. This literature review study aimed to investigate the effects of oocyte cryopreservation in both pre-maturation and post-maturation stages, the cryopreservation method and the type of cryoprotectants (CPA) used on the expression of some epigenetic-related genes and miRNAs.

AbstractBackground:The use of peritoneal catheters for prophylactic dialysis or drainage to prevent fluid overload after neonatal cardiac surgery is common in some centres; however, the multi-centre variability and details of peritoneal catheter use are not well described.Methods:Twenty-two-centre NEonatal and Pediatric Heart Renal Outcomes Network (NEPHRON) study to describe multi-centre peritoneal catheter use after STAT category 3–5 neonatal cardiac surgery using cardiopulmonary bypass. Patient characteristics and acute kidney injury/fluid outcomes for six post-operative days are described among three cohorts: peritoneal catheter with dialysis, peritoneal catheter with passive drainage, and no peritoneal catheter.Results:Of 1490 neonates, 471 (32%) had an intraoperative peritoneal catheter placed; 177 (12%) received prophylactic dialysis and 294 (20%) received passive drainage. Sixteen (73%) centres used peritoneal catheter at some frequency, including six centres in >50% of neonates. Four centres utilised prophylactic peritoneal dialysis. Time to post-operative dialysis initiation was 3 hours [1, 5] with the duration of 56 hours [37, 90]; passive drainage cohort drained for 92 hours [64, 163]. Peritoneal catheter were more common among patients receiving pre-operative mechanical ventilation, single ventricle physiology, and higher complexity surgery. There was no association with adverse events. Serum creatinine and daily fluid balance were not clinically different on any post-operative day. Mortality was similar.Conclusions:In neonates undergoing complex cardiac surgery, peritoneal catheter use is not rare, with substantial variability among centres. Peritoneal catheters are used more commonly with higher surgical complexity. Adverse event rates, including mortality, are not different with peritoneal catheter use. Fluid overload and creatinine-based acute kidney injury rates are not different in peritoneal catheter cohorts.
A Systematic Review of PPE Recommendations for First Responders, and Medical Professionals to Nuclear Radiological Events at Nuclear Power Plants
Authors: Noel Chaverle , Ryan Benjamin , Bruce Erica 
Published: June 2023

Introduction:Due to climate change, many countries are exploring nuclear power as a clean, sustainable, and alternative energy source. However, radiophobia stemming from a history of major accidents at nuclear power plants (most recently Fukushima Daiichi) inhibits the expansion of this industry. In an unlikely event of a large-scale accident, the risks posed to humans are minimal when mitigation measures are followed. This includes appropriate Personal Protective Equipment (PPE) for first responders, and medical professionals responding to these emergencies. An examination of the PPE recommendations for these scenarios will highlight best practices for minimizing exposures, and the effects of radiation.Method:A systematic literature review will provide a historical baseline of the PPE worn during previous nuclear power plant events. Additionally, current recommendations for PPE levels in response to these emergencies will be explored. Five databases will be utilized for this study, including PubMed, Web of Science, and SCOPUS.Results:Many studies examine different types of nuclear radiological exposures, but few focus on nuclear power plant scenarios. More than 5,000 articles emerged from a preliminary survey of the five databases. However, less than 1% of them satisfied the extraction criteria, and reviewed PPE for nuclear power plant accidents. Medical responders caring for “exposed” individuals who present at Emergency Departments have minimal exposure once they’re decontaminated, and everyday PPE is maintained. However, data on PPE recommendations for on-site response remains unexplored. Airtight suits and full-face respirators emerged as industry gold standard for protection, but a closer examination of these types of suits, and responders' self-efficacy utilizing the gear would clarify their actual protective qualities.Conclusion:While nuclear power plant accidents do not occur often, many remain fearful of their impact. Maintaining proper PPE (including respiratory habiliment) for event responders is one way to minimize the adverse health effects of these nuclear radiological exposures.
Closer Than We Think: the Management of a European Nuclear Exchange
Authors: Kucik Corry 
Published: June 2023

Introduction:An exhausted, isolated, increasingly desperate Russia, still in possession of over 4,400 nuclear warheads, puts the world at risk. Since the outbreak of war in Ukraine, Russian rhetoric and military doctrine have evinced an increasing nonchalance toward the employment of tactical nuclear weapons as stockpiles of conventional weapons are depleted. Poor targeting control (or outright perfidy), demonstrated by recent events in Poland possibly violating NATO’s collective defense clause, have only incensed an imminently combustible situation. Given this threat, it behooves medical professionals to gain thorough acquaintance with Acute Radiation Sickness (ARS), including an assessment of sources of exposure, presentation, prognostic indicators, immediate treatments, long-term concerns, and sources of consultant support.Method:Through thorough review of military and civilian sources, training courses, historical cases, injury mechanisms, first-responder concerns, hospitalization parameters, and laboratory indicators, the ARS spectrum will be explored. Surgical, anesthetic, and intensive care implications will be discussed, as will infection and nutritional concerns. Emerging practices, specialized therapy, and long-term medical sequelae will be covered.Results:A thorough discussion of potential sources (civil and military), clinical recognition, and presentation of ARS will focus on best clinical guidance, providing the most up-to-date treatment strategies, and will give clear guidance regarding how best to prepare, treat, and obtain specialist consultation.Conclusion:It is the earnest hope of the presenter (a senior naval physician with nuclear power experience, anesthesiology consultant/board examiner, and intensivist, who studied radiation safety and injury for much of his career and wrote a Diploma in the Medical Care of Catastrophes dissertation on radiologic injury management) that the audience will never face the horror of a single radiologic casualty. However, the likelihood of such wishful thinking seems as remote as ever. Attendees will not only learn guidance for treatment and prognostication, but will know how to obtain support and expert consultation.
Will they Panic? The Effect of Risk Messaging on Public Behavior During Non-conventional Terrorism
Authors: Bodas Moran , Ragoler Morel , Rabby Yossi , Krasner Esther 
Published: June 2023

Introduction:Non-conventional terrorism (NCT) is laced with uncertainty that can foster fear and lead to unwanted public behavior. One such example is the masses of worried-well overcrowding hospitals. The purpose of this study was to explore public behavioral intentions during NCT and the effect of risk messaging in attenuating unwanted behavior.Method:An online intervention-based study was conducted among 1,802 adult Israeli participants. Threat perception and behavioral intent before and after exposure to hypothetical NCT scenarios were assessed stratified to the media type, exposure to rumors and fake news, and risk messaging.Results:Participants perceived the CBRN terrorism threat as low-medium in likelihood, and threat intrusiveness and perceived incident severity were estimated at a medium level. Nearly half (45%) of participants indicated it is highly likely that they would seek medical attention following an NCT incident. Exposure to fake news significantly increased the intention to seek medical attention (p=0.001). However, the odds of participants exposed to risk messaging reporting this intention were 0.470 (95% CI: 0.359, 0.615) times that of participants not exposed to risk messaging (χ2=30.366, p<0.001).Conclusion:This study shows that overcrowding hospitals by worried-well following a non-conventional terror incident can be attenuated by risk messaging. In particular, this study suggests that simple, timely, and clear risk messaging is capable of overcoming fake news that otherwise can increase unwanted behavior. Rumors and fake news have limited power to alter threat perception, but they can significantly change behavioral intent and cause unwanted behavior that could jeopardize crisis management. Rational behavior by the public during NCT can be considered an outcome of rational decision-making by crisis managers, especially risk communicators.
The Impact of Chemical, Biological, Radiological, Nuclear and Explosive Events on Emergency Departments: An Integrative Review
Authors: Ranse Jamie , Mackie Benjamin , Heslop David , Currie Jane , Wilson Bridget , Crilly Julia , Mitchell Marion , Weber Sarah , Watkins Nathan , Sharpe Joseph , Handy Michael , Hammad Karen 
Published: June 2023

Introduction:Disasters occur globally and can impact emergency department (ED) services. Chemical, biological, radiological, and nuclear (CBRN) events have different characteristics in terms of onset and duration when compared to other disasters, such as wildfires, floods, and hurricanes. It is important to have an understanding of the impact of CBRN events on EDs to inform disaster preparedness. The purpose of this paper is to identify peer-reviewed published literature that describes the impact on EDs from CBRN events.Method:An integrative literature methodology was used, guided by the Preferred Reporting Items of Systematic reviews and Meta-Analysis (PRISMA) Guidelines. MEDLINE, PsycINFO, CINAHL, Pubmed, and Scopus were searched using terms relating to CBRN events and EDs. Papers were included if they focused on the impact of real-world CBRN event(s). Information from each included paper was extracted into a table, including author(s), CBRN event characteristics, ED response characteristics, patient presentation characteristics, and outcome characteristics.Results:Of the 15,982 studies that were identified from the database searches, 4,012 were duplicates and 11,696 were irrelevant at the title and abstract screening stage. Therefore, 274 were screened at the full-text stage resulting in 44 studies for inclusion. Included papers were mostly from the United States of America (n=22/44, 50%), followed by Turkey (n=4/44, 9.1%). Most of the events were chemical (n=36/44, 81.9%), with Chlorine (n=9/36, 25%) being the most frequently reported chemical agent. Between 1 and 5,500 people [M=54, IQR: 22-253] presented to EDs because of CBRN events.Conclusion:Emergency departments assess and manage patients who present following CBRN events. Of these patients, the majority do not require hospital admission, suggesting that the ED is integral in the health response to CBRN events. As such, EDs should be adequately prepared, from a resource and process perspective to assess, manage and discharge large numbers of CBRN-related patients.
Health and Social Implications of Potential Indo-Pacific Chemical, Biological, Radiological, and Nuclear (CBRN) Proliferation Driven by Adaptation to Population, Climate Change and Geopolitical Upheaval
Authors: Heslop David 
Published: June 2023

Introduction:Future strategic pressures in the Indo-Pacific region will present major policy and strategic challenges driven by rapidly increasing populations, resource depletion and contests, and forced adaptation to a changing climate. While regional countries remain likely to continue on a high growth trajectory, there is growing concern that nations will face difficulty to sustain economic gains in the face of strategic resource depletion and availability, population growth, and increasingly frequent extreme weather events. This mismatch could result in strategic miscalculation and reformulation, driving CBRN proliferation choices that fall outside of historical norms or standards. Such societal stressors are already occurring in the region and themselves may suddenly impact on health and social systems in unpredictable and complex ways.Method:Three tabletop exercises called the Boxwood Scenarios were conducted utilizing the Avalanche TTX system, including participants from key intelligence, military, and academic experts. Participants were invited to a Delphi study examining positive and negative drivers, shaping factors, motivators, and consequences of CBRNE proliferation in the Indo-Pacific region. Two rounds of result review were conducted by the group. These results underwent a systematic mixed methods analysis (quantitative and qualitative methods) and interpretation.Results:Climate change, demographic and geopolitical pressures were highlighted as key to future potential CBRN proliferation risks, with this nexus resulting in major proliferation concerns as early as 2040. Proliferation decisions driven by, and occurring in parallel to, climate and demographic pressures were identified as of major concern. Such decisions would have profound multi-layered social, health and broader implications for Indo-Pacific countries with declining determinants of national power.Conclusion:Climate change and demographic and geopolitical pressures could drive future Indo-Pacific CBRN proliferation. The consequences to human populations, the viability of ongoing international disaster risk reduction and capacity-building efforts, and the increased future risk of major CBRN events cannot be overstated.
Understanding the Healthcare Impacts of Attacks on Infrastructure

Published: June 2023

Introduction:Healthcare provision depends on reliable infrastructure to power equipment, and provide water for medication and sanitation. Attacks on infrastructure limiting such functions can have a profound and prolonged influence on the delivery of care.Method:A retrospective analysis of the Global Terrorism Database (GTD) was performed of all attacks occurring between 1970-2020. Data was filtered using the internal database search function for all events where the primary target was “Utilities”, “Food or Water Supply” and “Telecommunications.” For the purposes of this study the subtype “Food Supply” was excluded. Events were collated based on year, country, region, numbers killed and wounded.Results:The GTD listed 7,813 attacks on infrastructure with 6,280 attacks targeting utilities leading to 1,917 persons directly killed and 1,377 wounded. In total there were 1,265 attacks targeting telecommunications causing 205 direct deaths and 510 wounded. Lastly, 268 attacks targeted the water supply with 318 directly killed and 261 wounded. Regionally, South America had the most attacks with 2,236, followed by Central America and the Caribbean with 1,390. Based on infrastructure type, the most attacks on utilities occurred in El Salvador (1,061), the most attacks on telecommunications were in India (140) and Peru (46) had the most attacks on its water supply.Conclusion:The regions with the highest number of total attacks targeting infrastructure have historically been in South America, with more attacks against power and utilities than other infrastructure. The numbers of persons directly killed and wounded in these attacks were lower than those with other target types. However, the true impacts these attacks have on lack of health care delivery are not accounted for in these numbers. By understanding the pattern and scope of these attacks, Counter-Terrorism Medicine initiatives can be created to target harden healthcare-related infrastructure.
