This paper critically examines the ways ageing migrants perceive and experience a sense of belonging in a mediascape during the pandemic. It underscores how 15 elderly people from Culturally and Linguistically Diverse (CALD) backgrounds in Victoria, Australia stayed connected among their networks in and beyond Australia by accessing and consuming COVID-19 information via traditional and digital channels. By analysing the data based on conducting remote interviews in 2020 and 2021, the findings highlight the paradoxical nature of mediated belonging. On the one hand, ageing migrants forged connections at a distance with their familial and social networks by circulating and consuming COVID-19 information. This practice provided ageing migrants an assurance of their safety and their networks. On the other hand, differentiation and racialisation stirred frustrating, polarising and exclusionary-mediated environments. In this case, they deployed connective strategies to negotiate connections and belonging. In sum, this paper reveals the possibilities and politics of mediated belonging fuelled by intersecting structural and technological divides. [ABSTRACT FROM AUTHOR]

This paper explores social inclusion approaches implemented by ten secondary schools in Victoria, Australia, to support refugee students' well-being, as articulated in their policies, reports, and other published documents. Using an exploratory, qualitative research design, we found that all schools employed a holistic approach to implementing social inclusion programs for refugee students. This paper reports on the best practices and unique examples of social inclusion programs from all schools involved in the study. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic has given rise to diverse manifestations of racism in Australia, from everyday attacks against Asian Australians to discriminatory policies towards temporary migrants. Since the start of the pandemic, considerable knowledge on pandemic-related racism has been produced. This knowledge has yet to be consolidated, leaving questions about the nature, forms, impacts and trajectories of racism during the pandemic. This paper presents a systematic review and synthesis of research on racism during the pandemic, with an emphasis on pandemic-specific racism. We searched the databases Scopus, MEDLINE and PsycINFO for research published between January 2020 and July 2022. Eighteen research studies were included in the review, along with reports of routine data collection by five organisations. The research reviewed collected data mainly around the pandemic's 'second wave' in Australia (June-October 2020), focusing largely on Asian Australians and temporary migrants nationally and in Victoria. Widely studied forms of COVID-racism were verbal abuse, physical attacks, exclusion and Othering, and institutional racism involving governments, media and employers. We examined the pandemic's health and socio-economic impacts, and variations in experiences of racism over time between ethnic groups. As Australia emerges from the pandemic, we consider the review's implications for pandemic response, anti-racism practice and policy, and future research. [ABSTRACT FROM AUTHOR]

This paper presents a method to analyze and improve the set of equations constituting a rainfall‐runoff model structure based on a combination of a data assimilation algorithm and polynomial updates to the state equations. The method, which we have called "Data Assimilation Informed model Structure Improvement" (DAISI) is generic, modular, and demonstrated with an application to the GR2M model and 201 catchments in South‐East Australia. Our results show that the updated model generated with DAISI generally performed better for all metrics considered included Kling‐Gupta Efficiency, NSE on log transform flow and flow duration curve bias. In addition, the elasticity of modeled runoff to rainfall is higher in the updated model, which suggests that the structural changes could have a significant impact on climate change simulations. Finally, the DAISI diagnostic identified a reduced number of update configurations in the GR2M structure with distinct regional patterns in three sub‐regions of the modeling domain (Western Victoria, central region, and Northern New South Wales). These configurations correspond to specific polynomials of the state variables that could be used to improve equations in a revised model. Several potential improvements of DAISI are proposed including the use of additional observed variables such as actual evapotranspiration to better constrain internal model fluxes. Plain Language Summary: This paper presents a data‐driven method to improve rainfall‐runoff models used to generate future water resources scenario in climate change studies. The method, which we have called "Data Assimilation Informed model Structure Improvement" (DAISI) is generic, modular, and demonstrated with an application to monthly streamflow simulations over a large data set of catchments in South‐East Australia. Our results show that DAISI improves model performance for a wide range of metrics and increases the sensitivity of the model to climate inputs, which is critical in climate change scenarios. Finally, the improvements identified by DAISI take a simple mathematical form with distinct regional patterns in three sub‐regions of the study domain (Western Victoria, central region, and Northern New South Wales). Several improvements of DAISI are discussed including the inclusion of additional observed variables such as evapotranspiration to better constrain model simulations. Key Points: Data Assimilation Informed model Structure Improvement method diagnoses hydrological model structures by combining data assimilation with a polynomial update of state equationsThe method was applied to the GR2M rainfall‐runoff model with significantly improved streamflow simulations in 201 Australian catchmentsThe method identified updates to state equations with marked regional characteristics that could guide future improvement of GR2M [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic caused significant educational disruption globally. When the pandemic forced schools to switch to emergency home-schooling, parental engagement in education became more critical. Some parents found home-schooling as an opportunity to form stronger relationships with their children. Others acquired an enhanced insight into their children's schoolwork. However, the emerging literature shows that, as not all parents were equally positioned to support their children's learning at home, emergency home-schooling has resulted in a significant learning loss. Guided by the concept of capital interaction, this article reports on a qualitative case study that investigated the experiences of 20 migrant parents in Victoria, Australia. A thematic analysis of the data reveals challenges associated with parental self-efficacy, financial hardship, language and technological barriers, time constraints, and disengagement and exhaustion. Remote learning may return in the future, and we must prepare for such disruption by improving equitable access to education delivered online and at home. To this end, the paper outlines some policy ideas. [ABSTRACT FROM AUTHOR]

Background: This paper aimed to describe the legal worries of Australian general practitioners (GPs) and nurses regarding end-of-life care provided in the aged care setting. Methods: An analysis of responses to the final, open-ended question of a cross-sectional online survey of GPs and nurses practising in aged care settings in Queensland, New South Wales and Victoria was undertaken. Results: Of the 162 GPs and 61 nurses who gave valid responses to the survey, 92% (151 GPs and 55 nurses) responded to the open-ended question. Participants identified concerns across all relevant areas of end-of-life law. The most common concerns were substitute decision-makers or family member(s) wanting to overrule an Advance Care Directive, requests for futile or non-beneficial treatment and conflict about end-of-life decision-making. Participants often also identified concerns about their lack of legal knowledge and their fear of law or risk related to both end-of-life care generally and providing medication that may hasten death. Conclusions: Australian GPs and nurses working in aged care have broad-ranging legal concerns about providing end-of-life care. Legal concerns and knowledge gaps identified here highlight priority areas for future training of the aged care workforce. The law supports good end-of-life clinical practice by facilitating health care that aligns with the values and goals of patients, including those residing in residential aged care facilities. GPs and nurses here reported broad-ranging legal concerns relevant to providing end-of-life care within aged care, including substitute decision makers/family members wanting to overrule Advance Care Directives, requests for futile or non-beneficial treatment and conflict about decision-making. Participants' concerns can inform end-of-life legal training for aged care GPs and nurses. [ABSTRACT FROM AUTHOR]

Indigenous young people around the world suffer poorer mental health outcomes than their non-Indigenous peers. Currently, how culture matters for health, what cultural practices are used in community to support health and well-being, and how culture is passed on in Aboriginal contemporary life in southeast Australia--the region most affected by settler-colonisation--is not well understood. This paper presents findings from yarns with a representative sample of 44 Indigenous participants working in the field of health and well-being that explored how culture interleaves with health and well-being. It uses grounded theory as the overarching methodology with community participation in all aspects of the project. Participants were nominated through snowball sampling and screened by a governing board of Elders. They included men and women of varied ages with half residing in urban areas and half in rural Victoria, Australia. They had declared affiliations to 31 traditional tribal groups. The yarns were held over Zoom videoconferencing between an Indigenous research assistant who was part of the community, and each participant. Each yarn was recorded, transcribed, coded and analysed by a multi-perspectival team. Culture was viewed as central to individual and communal life and passed on through relationships with people and Country itself. Community members used a wide variety of cultural practices to aid and maintain health and wellbeing in profound ways. Myriad extant obstacles to health and well-being were also described, from experiences of disconnection through to barriers for accessing services. These findings have the potential to shape future holistic care and policy. [ABSTRACT FROM AUTHOR]

In recent years, deep learning (DL) approaches have been proven effective in addressing high nonlinear relationships within complex systems. Although various scientific studies have primarily focused on optimizing model architecture and enhancing its computational efficiency through hybridization, they have neglected the crucial aspect of selecting appropriate predictor variables (PV) and their influence on the model's predictions. In this paper, a new multi-phase stochastic DL model is designed with a feature selection framework for monthly streamflow prediction. The multi-phase hybrid MCMC–BC–BiLSTM–BiGRU model is based on bidirectional long short-term memory (BiLSTM) and bidirectional gated recurrent unit (BiGRU) integrated with Markov Chain Monte Carlo (MCMC) based bivariate copulas (BC). First, Ant Colony Optimization (ACO) algorithm was employed for screening optimal PV, and then significant antecedent streamflow was coupled with it to generate optimized input combinations. In addition, 25 different MCMC–BC models were adopted for each input combination to determine the dependency of previous month's streamflow on current and future streamflow. Finally, best-fitted MCMC–BC model was integrated with hybrid BILSTM–BiGRU model to predict streamflow at nine different catchments in the Victoria region of the Upper Murray Basin (UMB), Australia. The experimental results show that the multi-phase hybrid MCMC–BC–BiLSTM–BiGRU model showed remarkable performance in comparison to its benchmark counterparts with respect to different robust statistical error metrics. Therefore, this study demonstrates that stochastic DL techniques can be effectively employed as a promising alternative predictive tool for upstream discharge predictions with high consistency and accuracy, specifically when a statistically significant relationship with the antecedent streamflow exists.

Fair political representation is an important goal of democratic governments, yet Australia lags behind many democracies in women's representation in elected politics. Attacks against women in public spaces through harassment and verbal abuse have long constrained women's ease in physical spaces and, in the digital age, this has extended into online spheres. This paper examines the impact of on- and offline incivility on women's experiences in local politics. It focuses on Australia's southern state of Victoria and its 79 local government municipalities. We conduct two surveys of men and women elected representatives (N1 = 222, N2 = 205) to determine their experiences during the campaigning period and first year on council. We follow up with in-depth interviews with women who have experienced gender harassment (n = 10) to further understand its impacts. We offer new insights in to a 'push factor' that contribute to women leaving elected local government and their political underrepresentation. [ABSTRACT FROM AUTHOR]

The Australian government pays $6.7 billion per year in rebates to encourage Australians to purchase private health insurance (PHI) and an additional $6.1 billion to cover services provided in private hospitals. What is the justification for large government subsidies to a private industry when all Australians already have free coverage under Medicare? The government argues that more people buying PHI will relieve the burden on the public system and may reduce waiting times. However, the evidence supporting this is sparse. We use an instrumental variable approach to study the causal effects of higher PHI coverage in the area on waiting times in public hospitals in the same area. The instrument used is area-level average house prices, which correlate with average income and wealth, thus influencing the purchase of PHI due to tax incentives, but not directly affecting waiting times in public hospitals. We use 2014-2018 hospital admission and elective surgery waiting list data linked at the patient level from the Victorian Center for Data Linkage. These data cover all inpatient admissions in all hospitals in Victoria (both public and private hospitals) and those registered on the waiting list for elective surgeries in public hospitals in Victoria. We find that one percentage point increase in PHI coverage leads to about 0.34 days (or 0.5%) reduction in waiting times in public hospitals on average. The effects vary by surgical specialities and age groups. However, the practical significance of this effect is limited, if not negligible, despite its statistical significance. The small effect suggests that raising PHI coverage with the aim to taking the pressure off the public system is not an effective strategy in reducing waiting times in public hospitals. Alternative policies aiming at improving the efficiency of public hospitals and advancing equitable access to care should be a priority for policymakers., (© 2024 The Authors.

Background: Organisational health literacy is a promising area of research that enables a focus on how systems and services can be designed in ways that are responsive to populations with varying states and levels of health literacy, knowledge, and practices, including African refugees. The challenge is how organisations and professionals do this in practice, and research in this area is in its early stages. This qualitative study examined barriers to implementing health literacy responsive care practices in primary health care settings in Australia. It also offered suggestions to potentially address the barriers to improving organisational health literacy. Methods: Refugees (n = 19), primary health care professionals (n = 14), and other key stakeholders (n = 19) were recruited through convenience and snowball strategies from three states in Australia: New South Wales, Victoria, and Queensland. All but one participant was interviewed face-to-face via Zoom. Semi-structured interview guides were used to guide the conversations. Transcriptions from audio recordings were analysed using directed content analysis. Results: Thirteen themes were extracted from the data. Themes were organised into the following categories: structural and systemic, organisational context, individual professional level, individual patient level, and socio-community level. Major structural and system-level factors affecting organisational health literacy included rigid systems and structures and limited time. Key organisation-level factors included inflexible organisational processes and policies, institutionalised othering, discrimination and racism, and lack of interpreters. Individual professional factors were poor communication with patients and cultural knowledge gaps. Linguistic issues and service mistrust were key individual patient-level factors. Socio-community factors included limited community engagement. Participants identified potential solutions to help services navigate out of the barriers and improve their response to health literacy. Conclusion: The findings suggest that mainstream services and organisations could improve timely and appropriate health care access and utilisation for refugees through strategies such as designing services and health literacy programs with refugee communities, promoting health literacy champions in the workforce, integrating health literacy and culturally responsive care plans and strategies into organisational priorities.

Simple Summary: Free-roaming cats in urban areas are a source of nuisance complaints. In Australia, legislation relating to requirements that cat owners microchip and contain their cats on their property has been largely ineffective in reducing the number of free-roaming cats, because most are strays with no owner. Cats causing nuisance complaints are typically trapped and impounded, but only 7% of cats entering local government facilities are reclaimed by owners, with the remaining either rehomed or euthanized. Many healthy cats are euthanized, negatively impacting the staff involved. In 2013, the city of Banyule in Victoria funded and implemented a free program for cat sterilization, microchipping, and registration. The program was largely targeted at low-socioeconomic suburbs with the highest cat-related complaints and microtargeted at "hot-spots". Free transport of cats was offered to community members if needed. Stray cats fed by community members enrolled in the program became owned. Over 8 years, 33.0 cats/1000 residents were sterilized in the three target suburbs (average 4.1 cats/1000 per year). Key findings were city-wide decreases in impoundments by 66%, euthanasia by 82%, and cat-related calls by 36% over 8 years, with savings to council of AU $440,660 for an outlay of AU $77,490. In most states of Australia, local governments (councils) are responsible for the enforcement of legislation relating to domestic cats. Traditional methods used for cat management based on trap–adopt or euthanize programs have been ineffective, with cat-related calls and cat impoundments continuing to increase, resulting in many healthy cats being euthanized. This has detrimental effects on the mental health of animal management officers, staff in shelters and council facilities, and cat caregivers. The city of Banyule, Victoria, implemented a free cat sterilization, microchipping, and registration (licensing) program in 2013/14. Initially, it was targeted at three low-socioeconomic suburbs with the highest cat-related calls and intake, and was microtargeted at call locations. An average of 4.1 cats/1000 residents per year were sterilized over eight years. The program included stray cats being fed by caregivers, provided they took ownership. The program was later expanded city-wide. Over eight years, city-wide cat intake decreased by 66%, euthanasia by 82%, and cats reclaimed by owners increased from 6% of intake (2012/13) to 16% (2020/21). Cat-related calls decreased in the target area by 51%, and city-wide by 36%. The council realized cost savings of AU $440,660 associated with reduced costs for cat-related calls to council (AU $137,170) and charges from the contracted welfare agency (AU $303,490), for an outlay of AU $77,490 for sterilization costs. Instead of the traditional management of urban cats, proactive management based on targeted sterilization should be utilized by government and animal welfare agencies in Australia and internationally. These types of programs are effective at reducing cat intake and euthanasia and are cost-effective. [ABSTRACT FROM AUTHOR]

The Second World War saw a sharp rise in bigamy prosecutions in Australia. A variety of factors contributed to this phenomenon, from the whirlwind nature of romances contracted during wartime to increased detection resulting from investigations into military spousal support. This article explores the connections between bigamy prosecutions, war and military enlistment through archival records and media coverage of 159 cases committed for trial across 1914–1945 that involved active or returned servicemen as either bigamy defendants or victims of bigamous spouses. These cases also reveal shifting attitudes towards and experiences of bigamy, marriage, and gender in twentieth-century Australia. [ABSTRACT FROM AUTHOR]

Simple Summary: Jumps racing is a form of Thoroughbred horse racing that involves hurdles and steeples and typically longer distances and heavier weights compared with flat racing, which does not incorporate obstacles. The continuation of jumps racing remains contentious due to the higher risk of fatalities, falls and injuries for horses, compared with flat racing. In Australia, jumps racing is carried out only in the state of Victoria after a legislated ban on jumps racing in South Australia in 2022. Jumps races account for only 1.8% of Thoroughbred horse races in Victoria. This study compared the incidence of fatalities, falls and injuries in horses participating in hurdle and steeplechase races with those participating in flat races at the same race meets, for all jumps races in the 2022 and 2023 Thoroughbred horse jumps racing seasons in Victoria, Australia. Overall, horse fatalities, falls and injuries occurred at higher rates in jumps races compared with flat races during the study period. Jumps racing is a form of Thoroughbred horse racing that involves hurdles and steeples and typically longer distances, and heavier weights compared with flat racing, which does not incorporate obstacles. In Australia, jumps racing is carried out only in Victoria, one of eight states and territories. The continuation of jumps racing is contentious due to the higher risk of fatalities, falls and injuries for horses, compared with flat racing. While measures have been introduced by the industry to improve the safety of riders and horses, the rates of fatalities, falls and injuries in horses participating in jumps races have not been collectively reported in Australia since the 2012 to 2014 race seasons. Although information on individual horse fatalities, falls and injuries is published by Racing Victoria in Stewards' Reports, the data are not aggregated, and so cannot readily be used to assess trends or evaluate the efficacy of safety measures introduced by the industry. The aim of this study was to determine the fatality, fall and injury rates for horses participating in hurdle and steeplechase races in Victoria in the 2022 and 2023 Thoroughbred horse jumps racing seasons compared with horses participating in flat races at the same race meets. Data on horse fatalities, falls and injuries were extracted from the published Racing Victoria race results and Stewards' Reports for the jumps races (n = 150) and corresponding flat races (n = 157) held at the 38 jumps race meets in Victoria in 2022 and 2023. Overall, horse fatalities, falls and injuries occurred at higher rates in jumps races compared with flat races during the study period. The rate of horse fatalities in jumps races was 3.3 per 1000 starts, with no fatalities in flat races. The rate of horse falls in hurdle races was 24 per 1000 starts and 41.6 per 1000 starts in steeplechase races, comparable with rates previously reported in the 2012 to 2014 seasons. There were no falls in flat races. Horse injuries occurred at a rate of 68.9 per 1000 starts in jumps races compared with 18.8 per 1000 starts in flat races. In hurdle and steeplechase races, veterinary clearance being required following horse injury was 5.4 times (OR 5.4, 95% CI 2.8–10.2) and 7.2 times (OR 7.2, 95% CI 3.3–15.6) more likely, respectively, compared with flat races. The risk of trauma was 4 times more likely in hurdle and steeplechase races (OR 4.8, 95% CI 1.7–13.3 and OR 4.1, 95% CI 1.2–13.4, respectively) and the risk of lameness was increased by 2.5 times in hurdles (OR 2.5, 95% CI 1.2–5.2) and 5.1 times in steeplechase races (OR 5.1, 95% CI 2.3–11.5), compared with flat races. These findings support concerns about the welfare of horses involved in jumps racing and of the need for further safety measures to reduce these risks. [ABSTRACT FROM AUTHOR]

Introduction: Effective primary healthcare services have been identified by the World Health Organization as the most equitable approach to enhancing universal healthcare. Robust models of mentoring for registered nurses (RNs) transitioning to primary healthcare roles have yet to be described in the Australian context. A robust mentoring model can support RNs to fulfill their potential, bridging the gap between theory and practice. In 2015, the peak body for nurses in primary health care (PHC) began developing a transition to practice program, including embedded mentoring to support newly graduated and more experienced registered and enrolled nurses. This quality improvement study reports the experiences and perspectives of nurses participating as mentors in two separate offerings of the program delivered between 2019 and 2021. Method: A two-phase concurrent mixed methods evaluation utilized data from pre- and post online surveys and post program meetings. Quantitative items underwent descriptive analyses. Thematic analysis of free-text responses and comments was conducted independently by two researchers. Mentors voluntarily provided self-report data and were informed that data is routinely collected to support continuous quality improvement processes for all programs. An Information Sheet informed mentors of data usage, confidentiality, and options to withdraw without penalty from the program at any time. Results: Seventy-nine mentors were recruited to support two groups of nurses (N = 111). Mentor self-rated overall satisfaction with program participation was 86.67% (very or extremely satisfied). Mentors described being "witness to mentee growth," "having facilitated access to learning" and receiving "unexpected benefits" including personal and professional growth and enhanced enthusiasm for their role in PHC. Conclusion: The embedded mentoring reported in this article combined a focus on skills acquisition and professional identity with the provision of a range of resources and support activities. Sustainable mentoring programs will be an important mechanism for supporting the expanding roles required of nurses working in primary health. [ABSTRACT FROM AUTHOR]

Purpose: Schools have long been perceived as an ideal setting to support the healthy eating behaviours of children. The aim of the study was to examine the views of Australian primary school parents regarding school food and nutrition, including education, practices and policy. Design/methodology/approach: An online survey was conducted among 787 parents in March 2021, which included closed and open-ended questions. Findings: The results indicated the inconsistent implementation of policies and/or varying practices among different schools. Parents' views were slightly associated with some demographic and personal measures including their SES levels, education, age, the main language spoken at home and universalism values. Parents viewed healthy food provision through canteens, policies and informing parents, fruit and vegetable breaks and kitchen and garden programs as the main contributors to the promotion of healthy eating. They believed unhealthy options in canteens, school fairs, events and birthdays are the major contributors to the formation of unhealthy eating habits among children at schools. Results revealed the efforts to establish health promoting school food environments in Australian primary schools; however, inconsistencies and discrepancies among schools should be addressed to ensure equity among all children. Practical implications: The findings may provide directions for policymakers and school managers and can inform future reforms and initiatives in Australian primary schools and elsewhere. Originality/value: This is the first study that has examined Australian parents' views of school food policy, practices and environments using a mixed-methods design. [ABSTRACT FROM AUTHOR]

Background: A knowledge gap exists regarding longitudinal assessment of personal radio-frequency electromagnetic field (RF-EMF) exposures globally. It is unclear how the change in telecommunication technology over the years translates to change in RF-EMF exposure. This study aims to evaluate longitudinal trends of micro-environmental personal RF-EMF exposures in Australia., Methods: The study utilised baseline (2015-16) and follow-up (2022) data on personal RF-EMF exposure (88 MHz-6 GHz) measured across 18 micro-environments in Melbourne. Simultaneous quantile regression analysis was conducted to compare exposure data distribution percentiles, particularly median (P 50 ), upper extreme value (P 99 ) and overall exposure trends. RF-EMF exposures were compared across six exposure source types: mobile downlink, mobile uplink, broadcast, 5G-New Radio, Others and Total (of the aforementioned sources). Frequency-specific exposures measured at baseline and follow-up were compared. Total exposure across different groups of micro-environment types were also compared., Results: For all micro-environmental data, total (median and P 99 ) exposure levels did not significantly change at follow-up. Overall exposure trend of total exposure increased at follow-up. Mobile downlink contributed the highest exposure among all sources showing an increase in median exposure and overall exposure trend. Of seven micro-environment types, five of them showed total exposure levels (median and P 99 ) and overall exposure trend increased at follow-up., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

While numerous studies have examined the factors that influence crash occurrence, there remains a gap in understanding the intricate relationship between built environment, traffic flow, and crash occurrences across different spatial units. This study explores how built environment attributes, and dynamic traffic flow characteristics affect crash frequency by focusing on proposed traffic density-based zones (TDZs). Utilizing a comprehensive dataset from Greater Melbourne, Australia, this research emphasizes on the dynamic traffic flow variables and insights from the Macroscopic Fundamental Diagram model, considering parameters such as shockwave velocity and congestion index. The association between the potential influencing factors and crash frequency is examined using a random parameter negative binomial regression model. Results indicate that the data segmentation based on TDZs is instrumental in establishing a more refined crash model compared to traditional planning-based zones, as demonstrated by improved goodness-of-fit measures. Factors including density (e.g., employment density), network design (e.g., road density and highway density), land use diversity (e.g., job-housing balance and land use mixture), and public transit accessibility (e.g., bus route density) are significantly associated with crash occurrence. Furthermore, the unobserved heterogeneity effects of the shockwave velocity and congestion index on crashes are revealed. The study highlights the significance of incorporating dynamic traffic flow variables in understanding crash frequency variations across different spatial units. These findings can inform optimal real-time traffic monitoring, environmental design, and road safety management strategies to mitigate crash risks., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.
