Authors: Centelles Xavier , Castro J. Ramon , Pelayo F. , Aenlle-López Manuel , Cabeza Luisa F. 
Published: September 2021

AbstractLaminated glass beams without metallic or polymeric reinforcements generally lack post-breakage strength and ductility. This paper aims to perform a comparative study by testing five different fully transparent laminated glass beam designs in order to see how parameters such as the number and thickness of glass sheets (3 x 10 mm or 5 x 6 mm), the interlayer material (PVB Clear or SentryGlas), and the thermal treatment of glass (annealed or heat-strengthened) affect the pre-breakage performance and post-breakage safety. A buckling analysis is also performed using a numerical model with ABAQUS CAE. The study includes a comparison between the results of different experimental mechanical tests on laminated glass beams, including the tests presented in this paper, as well as other tests found in the literature. All designs presented a linear elastic behaviour until initial breakage. The interlayer material mainly affected the crack shape of laminated glass beams. Beams with five sheets of annealed glass had a more progressive breakage, and therefore a safer behaviour, than beams with three sheets of annealed or heat-strengthened glass.
Mothers in Mind: Exploring the Efficacy of a Dyadic Group Parenting Intervention for Women Who Have Experienced Intimate Partner Violence and Their Young Children

Published: September 2021

AbstractIdentifying and responding to the mental health needs of young children (0–4 years) exposed to intimate partner violence is one of the most pressing issues confronting child mental health and welfare sectors today. Children exposed to IPV (CEIPV) are at an increased risk of experiencing maltreatment, developing emotional and behavioral problems, and experiencing other adversities (Kimball, Journal of Family Violence, 31, 625–637, 2016). Among the range of protective factors that can mitigate against this impact is a strong relationship with, and attachment to, a primary caregiver (Holt, Buckley, & Whelan, Child Abuse & Neglect, 32, 797–810, 2008). Despite this, there are few evidenced-based programs which address the unique parenting supports required by women who experience domestic violence, while simultaneously attending to the unique developmental and psycho-social needs of exposed young children (Austin, Shanahan, Barrios, & Macy, Trauma, Violence and Abuse, 20(4), 498–519, 2019). This article describes the development and preliminary evaluation of Mothers in Mind, a trauma-informed, dyadic, mother–child intervention program designed to meet this need. Analyses of data from 36 mother–child dyads who completed pre- and post-group evaluation find that, after program completion, mothers report greater parenting self-efficacy, healthier parenting, and enhanced psychological well-being. The importance of relational capacity building in mother–child dyads impacted by violence and suggestions for future avenues for research and intervention are explored.

Published: September 2021

AbstractEffective and consistent engagement in personal hygiene practices is important for preventing the acquisition and transmission of communicable diseases in childhood. This study aimed to investigate trends in adherence to recommended hygiene practices and identify factors contributing to difficulties in establishing good hygiene habits with young children (0–4 years) in Australia. A self-selected community sample of parents (N = 426) completed an online survey assessing children's adherence to recommended hygiene practices and barriers and enablers of establishing good personal hygiene habits. Parents reported interest in receiving information/tips on children's personal hygiene (yes/no) and nominated topics of interest. Less than half of children in any age group consistently (always/almost always) covered coughs and sneezes, washed hands after toileting, or washed hands before meals or when dirty. Children's non-compliance (i.e. resistance, refusal) was the most commonly reported barrier to establishing good personal hygiene habits, while children's compliance (i.e. cooperative behaviour, following or complying with caregivers’ instructions) was the most commonly cited enabler. Despite low levels of adherence, less than half (41.2%) of parents wanted information/tips on children's hygiene. Results suggest a disconnect between parents’ knowledge about recommended hygiene practices and actual behaviour. Development and testing of approaches to behaviour change that incorporate evidence-based strategies to manage children's resistance and support parents to encourage the development of healthy hygiene habits is warranted.
Stochastic properties of generalized finite mixture models with dependent components
Authors: Amini-Seresht Ebrahim , Balakrishnan Narayanaswamy 
Published: September 2021

AbstractIn this paper we consider a new generalized finite mixture model formed by dependent and identically distributed (d.i.d.) components. We then establish results for the comparisons of lifetimes of two such generalized finite mixture models in two different cases: (i) when the two mixture models are formed from two random vectors
$\textbf{X}$
and
$\textbf{Y}$
but with the same weights, and (ii) when the two mixture models are formed with the same random vectors but with different weights. Because the lifetimes of k-out-of-n systems and coherent systems are special cases of the mixture model considered, we used the established results to compare the lifetimes of k-out-of-n systems and coherent systems with respect to the reversed hazard rate and hazard rate orderings.

AbstractObjectiveTo study the impact of telemedicine on patient outcomes during a nationwide lockdown to halt the spread of coronavirus disease 2019.MethodsA retrospective study was conducted to examine telemedicine consultations of newly referred patients over 7 days during a national lockdown. Overall outcomes of telephone clinics were recorded, measured as either patient discharged, imaging requested, patient referred to another specialty, further telephone follow up required, patient initiated follow up or face-to-face appointment required.ResultsData were collected from 104 patients. Outcomes showed that 17 patients were discharged, 15 had imaging requested, 11 were referred to another specialty, 11 had further telemedicine appointments, 31 had patient-initiated follow up and 19 received face-to-face appointments. Overall, 57 per cent of patients avoided hospital visits and 17 per cent required face-to-face appointments. Of higher risk patients, 49 per cent were managed remotely. After eight months, no significant morbidity or mortality was reported.ConclusionAlmost half of the higher risk patients avoided a hospital visit. The majority of patients were managed remotely, and thus the risk and spread of infection were reduced. Telemedicine has an important role in ENT out-patients.
Use of a dissected intravenous giving set to assist large metal oesophageal foreign body removal in rigid oesophagoscopy

Published: September 2021

AbstractBackgroundOesophageal foreign body removal may be challenging. If a foreign body is sufficiently high risk and cannot be retrieved via oesophagoscopy, laparotomy may be required as the foreign body migrates distally.ObjectiveThis paper presents the use of the plastic tubing from an intravenous giving set, combined with rigid oesophagoscopy grasping forceps, in order to improve purchase and obtain sufficient traction on a large, smooth, metallic distal oesophageal foreign body (knife).Results and conclusionThis method offers an option for removal of oesophageal foreign bodies that may be rendered challenging with traditional metal grasping forceps given the lack of purchase and traction afforded by a ‘metal on metal’ grip, potentially avoiding the need for open surgery.
How children learn to communicate discriminatively
Authors: RAMSCAR Michael 
Published: September 2021

AbstractHow do children learn to communicate, and what do they learn? Traditionally, most theories have taken an associative, compositional approach to these questions, supposing children acquire an inventory of form-meaning associations, and procedures for composing / decomposing them; into / from messages in production and comprehension. This paper presents an alternative account of human communication and its acquisition based on the systematic, discriminative approach embodied in psychological and computational models of learning, and formally described by communication theory. It describes how discriminative learning theory offers an alternative perspective on the way that systems of semantic cues are conditioned onto communicative codes, while information theory provides a very different view of the nature of the codes themselves. It shows how the distributional properties of languages satisfy the communicative requirements described in information theory, enabling language learners to align their expectations despite the vastly different levels of experience among language users, and to master communication systems far more abstract than linguistic intuitions traditionally assume. Topics reviewed include morphological development, the acquisition of verb argument structures, and the functions of linguistic systems that have proven to be stumbling blocks for compositional theories: grammatical gender and personal names.

Abstract
Little is known about the impact of COVID-19 on the outcomes of patients undergoing surgery and intervention. This study was conducted between 20 March and 20 May 2020 in six hospitals in Istanbul, and aimed to investigate the effects of surgery and intervention on COVID-19 disease progression, intensive care (ICU) need, mortality and virus transmission to patients and healthcare workers. Patients were examined in three groups: group I underwent emergency surgery, group II had an emergency non-operating room intervention, and group III received inpatient COVID-19 treatment but did not have surgery or undergo intervention. Mortality rates, mechanical ventilation needs and rates of admission to the ICU were compared between the three groups. During this period, patient and healthcare worker transmissions were recorded. In total, 1273 surgical, 476 non-operating room intervention patients and 1884 COVID-19 inpatients were examined. The rate of ICU requirement among patients who had surgery was nearly twice that for inpatients and intervention patients, but there was no difference in mortality between the groups. The overall mortality rates were 2.3% in surgical patients, 3.3% in intervention patients and 3% in inpatients. COVID-19 polymerase chain reaction positivity among hospital workers was 2.4%. Only 3.3% of infected frontline healthcare workers were anaesthesiologists. No deaths occurred among infected healthcare workers. We conclude that emergency surgery and non-operating room interventions during the pandemic period do not increase postoperative mortality and can be performed with low transmission rates.

Published: September 2021

AbstractObjective:Disaster impact databases are important resources for informing research, policy, and decision making. Therefore, understanding the underpinning methodology of data collection used by the databases, how they differ, and quality indicators of the data recorded is essential in ensuring that their use as reference points is valid.Methods:The Australian Disaster Resilience Knowledge Hub (AIDRKH) is an open-source platform supported by government to inform disaster management practice. A comparative descriptive review of the Disaster Mapper (hosted at AIDRKH) and the international Emergency Events Database (EM-DAT) was undertaken to identify differences in how Australian disasters are captured and measured.Results:The results show substantial variation in identification and classification of disasters across hazard impacts and hazard types and a lack of data structure for the systematic reporting of contextual and impact variables.Conclusions:These differences may have implications for reporting, academic analysis, and thus knowledge management informing disaster prevention and response policy or plans. Consistency in reporting methods based on international classification standards is recommended to improve the validity and usefulness of this Australian database.
Hidden depths: diversity, difference and the High Court of Australia
Authors: Cahill-O'Callaghan Rachel , Roberts Heather 
Published: September 2021

AbstractThere is a growing international emphasis on the importance of diversity in the judiciary and the impact of the individual in decision-making. However, it can be a challenge to gain insight into the individuals who sit on the bench. For instance, there is limited official information about the individuals who sit on the High Court of Australia. One of the rare glimpses provided by the justices themselves is their judicial swearing-in speech. Drawing on a case-study of the swearing-in speeches of High Court justices sitting between 2008 and 2016, this paper illustrates how these speeches can illuminate key demographic information about the judiciary, as well as facets of the individual rarely explored in studies of judicial diversity: personality and values. This study demonstrates how swearing-in speeches can assist with filling information gaps about judicial diversity, and so extend debates about judicial selection.
Potential of Clumped Isotopes in Constraining the Global Atmospheric Methane Budget
Authors: Chung Edward , Arnold Tim 
Published: September 2021

AbstractAtmospheric methane (CH4) and its isotopic composition trends over the last decades are explained by various flux scenarios, from tropical wetland emission increases through to reductions in global hydroxyl (OH). In this study, we develop a modeling framework to assess the potential usefulness of clumped isotope measurements to distinguish between the main drivers of change in the CH4 burden. We model interhemispheric differences of 0.12‰ and 0.38‰ and seasonal cycles of 0.02‰–0.04‰ and 0.21‰–0.32‰ for Δ13CH3D and Δ12CH2D2, respectively, which is insignificant relative to the uncertainty of measurements that could eventually be made. We show, however, that measurements of Δ12CH2D2 specifically could provide constraints for understanding trends in the global total source and sink magnitudes, which has not been possible with the current sets of observables. Changes in OH concentration of 10% developed across three decades result in a difference of up to 2‰ in Δ12CH2D2, which would be observable given current measurement uncertainty limits. For this type of global‐scale analysis, we show that measurements of Δ13CH3D would be unlikely to provide additional useful information. We suggest an emphasis should now be on developing the methods to make measurements from ambient air samples, followed by measurements of Δ13CH3D and Δ12CH2D2 from sampling at clean Northern and Southern Hemisphere sites, combined with more accurate and precise laboratory measurements of the clumped kinetic isotope effects relevant for the atmospheric sinks.

AbstractWe use in situ environmental measurements by the Mars Science Laboratory (MSL) mission to obtain the surface energy budget (SEB) across Curiosity's traverse during the first 2500 sols of the mission. This includes values of the downwelling shortwave solar radiation, the upwelling solar radiation reflected by the surface, the downwelling longwave radiation from the atmosphere, the upwelling longwave radiation emitted by the surface, the sensible heat flux associated with turbulent motions, and the latent heat flux associated with water phase changes. We then analyze their temporal variation on different timescales and relate this to the mechanisms causing these variations. Through its Rover Environmental Monitoring Station, MSL allows for a more accurate determination of the SEB than its predecessors on Mars. Moreover, the unprecedented duration, cadence, and frequency of MSL environmental observations allow for analyses of the SEB from diurnal to interannual timescales. The results presented in this article can be used to evaluate the consistency with predictions from atmospheric numerical models, to validate aerosol radiative properties under a range of dust conditions, to understand the energy available for solar‐powered missions, and to enable comparisons with measurements of the SEB by the Perseverance rover at Jezero crater.
Achieving Equilibrium as a Semi‐Alluvial Channel: Anthropogenic, Bedrock, and Colluvial Controls on the White Clay Creek, PA, USA

Published: September 2021

AbstractBased on well‐developed hydraulic geometry relations for width and depth, classic studies initially interpreted the Mid‐Atlantic White Clay Creek (WCC) as a quasi‐equilibrium, alluvial channel. Subsequent studies document the legacy of colonial‐age watershed disturbances and urban development, confounding earlier classifications. To investigate this matter, we contribute new data from reach‐scale geomorphic mapping, and observations and modeling of bed material transport. WCC's longitudinal profile reflects a history of bedrock incision, while hydraulic geometry equations for width and depth indicate quasi‐equilibrium cross‐sectional adjustment. Alluvial landforms such as pools and riffles, bars, and actively forming floodplains occur at all 12 study sites, but exposures of bedrock and colluvium are also common. The ratio of bankfull to threshold Shields stress averages 1.41 (range: 0.41–2.63), suggesting that WCC is an alluvial, threshold, gravel‐bed river. However, a numerical model of WCC bed material transport and grain size, calibrated to bedload tracer data, demonstrates that 22% (range: 8%–73%) of bed material is composed of immobile, locally sourced cobbles and boulders, while the remaining bed material represents mobile, sand to cobble‐sized alluvium; this leads us to classify WCC as a semi‐alluvial river. Additional computations suggest that channel morphology is insensitive to bed material supply. Field observations imply that bankfull Shields stresses do not represent channel adjustments to achieve stable banks; rather, width adjustment likely reflects cohesive bank processes. Despite the numerous and contradictory labels applied to WCC (i.e., quasi‐equilibrium, Anthropocene, bedrock, semi‐alluvial, and gravel‐bed), each term contributes insight that any single conceptual model would be unable to provide alone.

AbstractIncreased use of phosphorus (P) fertilizers and detergents and intensified livestock production have more than doubled P inputs to human‐impacted watersheds over pre‐industrial levels. While P fertilizer use and manure application help to maximize crop yields, excess P is lost to runoff, leading to eutrophication of downstream waters. Excess P also accumulates across the landscape, leading to legacies that serve as long‐term sources of P to surface waters, even after inputs to the watershed are reduced. Here, we have developed, for the first time, a process‐based model, Exploration of Long‐tErM Nutrient Trajectories‐Phosphorus, designed to capture legacy P accumulation and depletion trajectories along the land‐aquatic continuum. To drive the model, we have developed a more than 100‐year trajectory of watershed P inputs to the Grand River Watershed (GRW), Canada’s largest watershed draining directly to Lake Erie. Our results first show that net P inputs to the watershed approximately tripled between 1900 and the late‐1970s, when P surplus magnitudes peaked at approximately 15 kg ha−1 y−1. During this same period, stream P loads have increased more than fourfold, from 0.11 kg ha−1 y−1 in 1900 to 0.80 kg ha−1 y−1 in the 1970s. Since 1900, the GRW has served as a net P sink, with approximately 96% of net P inputs having been retained within the basin. Future simulations suggest that while 40% reductions in P loading in Lake Erie watersheds are possible under aggressive management scenarios, legacy P will continue to elevate P loads to Lake Erie for many decades to come.
A Preliminary Regional Geomorphologic Map in Utopia Planitia of the Tianwen‐1 Zhurong Landing Region

Published: September 2021

AbstractA geomorphologic map is an important step to understanding the geologic context and history of a site; here, we present an initial geomorphologic map for an area spanning 22°–26°N, 108°–112°E in the Utopia Planitia (UP) region on Mars. This site is of special interest because it contains the May 2021 landing site of the Zhurong rover from Tianwen‐1. Utopia Planitia exhibits many lobate features that have been proposed to be lava or mud flows. Lander and rover data should help solve the scientific question concerning the origin of UP flows. We use our map to generate an initial stratigraphic framework of geomorphological features in order to help place future Zhurong data into the regional geologic context. Our mapping effort has detailed the distribution of three geomorphologic units and 11 types of surface features.

Published: September 2021

AbstractWe present a study of decameter scale ionospheric irregularities using in‐situ electron density data from the NorSat‐1 satellite. During the current period of low solar activity, NorSat‐1 frequently observes significant plasma irregularities from several 10 s km down to several decameter. These are often observed near the dayside cusp and dawnside auroral zone. The decameter‐scale irregularities are positively correlated with intermediate‐scale (10 km) density gradients, for both negative and positive gradients encountered by the satellite. The statistical distribution of electron density over two winter months in the northern hemisphere along NorSat‐1 orbits, shows significant density increases in the cusp ionosphere (75°–80° Magnetic LATitude) and in regions near the dawnside auroral oval. Intermediate scale density gradients and small‐scale irregularities are clearly associated with these density enhancements. We postulate that these density enhancements and irregularities are due to auroral particle precipitation/plasma dynamics.
