AbstractQuasi-two dimensional (2D) perovskites have emerged as a promising class of materials due to their remarkable photoluminescence efficiency, which stems from their exceptionally high exciton binding energies. The spatial confinement of excitons within smaller grain sizes could enhance the formation of biexcitons leading to higher radiative recombination efficiency. However, the synthesis of high-quality quasi-2D perovskite thin films with controllable grain sizes remains a challenging task. In this study, we present a facile method for achieving quasi-2D perovskite thin films with controllable grain sizes ranging from 500 to 900 nm. This is accomplished by intermediate phase engineering during the film fabrication process. Our results demonstrate that quasi-2D perovskite films with smaller grain sizes exhibit more efficient bound exciton generation and a reduced stimulated emission threshold down to 15.89 µJ cm−2. Furthermore, femtosecond transient absorption measurements reveal that the decay time of bound excitons is shorter in quasi-2D perovskites with smaller grain sizes compared to that of those with larger grains at the same pump density, which is 230.5 ps. This observation suggests a more efficient exciton recombination process in the smaller grain size regime. Our findings would offer a promising approach for the development of efficient bound exciton lasers.
Study on electric towing tractor quantity based on cellular automata

Published: October 2024

AbstractAircraft ground taxiing contributes significantly to carbon emissions and engine wear. The electric towing tractor (ETT) addresses these issues by towing the aircraft to the runway end, thereby minimising ground taxiing. As the complexity of ETT towing operations increases, both the towing distance and time increase significantly, and the original method for estimating the number of ETTs is no longer applicable. Due to the substantial acquisition cost of ETT and the need to reduce waste while ensuring operational efficiency, this paper introduces for the first time an ETT quantity estimation model that combines simulation and vehicle scheduling models. The simulation model simulates the impact of ETT on apron operations, taxiing on taxiways and takeoffs and landings on runways. Key timing points for ETT usage by each aircraft are identified through simulation, forming the basis for determining the minimum number of vehicles required for airport operations using a hard-time window vehicle scheduling model. To ensure the validity of the model, simulation model verification is conducted. Furthermore, the study explores the influence of vehicle speed and airport scale on the required number of ETTs. The results demonstrate the effective representation of real-airport operations by the simulation model. ETT speed, airport runway and taxiway configurations, takeoff and landing frequencies and imbalances during peak periods all impact the required quantity of ETTs. A comprehensive approach considering these factors is necessary to determine the optimal number of ETTs.

Published: October 2024

Abstract

Introduction:
Operationalizing multi-site Community Engagement (CE) Studios to inform a research program is valuable for researchers. We describe the process and outcomes of hosting three CE Studios with Community Experts aged 65 years or older with chronic conditions and care partners of older adults. Experts gave feedback about processes for testing the feasibility, efficacy, effectiveness, and implementation of audio recording clinic visits and sharing recordings with patients who have multimorbidity and their care partners.

Methods:
The CE Cores of the Clinical and Translational Science Awards Programs at three academic health science centers created a joint CE Studio guide. Studios were conducted iteratively by site. Following receipt of the final reports, responses were compared to find themes, similarities, and differences on four topics in addition to overall commentary: Recruitment and Retention, Study Protocol, Study Reminders and Frequency, and Recording Technology.

Results:
Eighteen older adults and care partners in three states provided valuable feedback to inform multi-site trials. Feedback influenced multiple aspects of trials in process or subsequently funded. Experts provided critique on the wording of study invitations, information sheets, and reminders to engage in study procedures. Experts were concerned for participants being disappointed by randomization to a control arm and advised how investigators should prepare to address that.

Conclusions:
Multi-site CE Studios should be consecutive, so each team can learn from the previous teams. Using the CES Toolkit ensures that final reports were easily comparable and utilized to develop a research program that now includes three federally funded clinical trials.

Abstract
Evaluation of benefits beyond quantitative academic outputs is essential in determining translational research value. We used the Translational Science Benefits Model (TSBM) to examine the impact of the QUARTET USA trial using 30 benefits across 4 domains: Clinical, Community, Economic, and Policy. We found that the QUARTET USA trial demonstrated impact in six areas within the Clinical, and Community domains and had potential impact in two additional areas within the Community and Economic domains. Use of the TSBM supports the value of the QUARTET USA trial, which can be used as a template for future cardiovascular trials.

Abstract
Crowd monitoring for sports games is important to improve public safety, game experience, and venue management. Recent crowd-crushing incidents (e.g., the Kanjuruhan Stadium disaster) have caused 100+ deaths, calling for advancements in crowd-monitoring methods. Existing monitoring approaches include manual observation, wearables, video-, audio-, and WiFi-based sensing. However, few meet the practical needs due to their limitations in cost, privacy protection, and accuracy.
In this paper, we introduce a novel crowd monitoring method that leverages floor vibrations to infer crowd reactions (e.g., clapping) and traffic (i.e., the number of people entering) in sports stadiums. Our method allows continuous crowd monitoring in a privacy-friendly and cost-effective way. Unlike monitoring one person, crowd monitoring involves a large population, leading to high uncertainty in the vibration data. To overcome the challenge, we bring in the context of crowd behaviors, including (1) temporal context to inform crowd reactions to the highlights of the game and (2) spatial context to inform crowd traffic in relation to the facility layouts. We deployed our system at Stanford Maples Pavilion and Michigan Stadium for real-world evaluation, which shows a 14.7% and 12.5% error reduction compared to the baseline methods without the context information.
Enhancing First Responder Safety in Nuclear Radiological Emergencies: A Systematic Literature Review of Personal Protective Equipment (PPE) Training to Promote Self-Efficacy Among First Responders
Authors: Noel Chaverle K , Bruce Erica , Ryan Benjamin 
Published: October 2024

Abstract

Objective
Nuclear radiological emergencies are classified as low frequency, but high impact events. Radiophobia and fear of deleterious outcomes often evokes hesitancy among responders. This review explored PPE use as a protective mechanism for responders’ safety and identified tools that promote PPE efficacy among first responders during nuclear radiological events.

Methods
A systematic literature review was conducted using five scientific databases. More than 5,500 articles were screened to identify literature relating to “PPE use” by first responders during “nuclear radiological events”.

Results
Regulatory agencies such as the IAEA and the NRC assert that PPE, (when worn correctly and consistently) minimizes radiation exposure. Adequate training of first responders emerged as a critical determinant to support appropriate PPE selection and usage during radiological emergencies. This included new employee trainings and refresher courses for existing employees. Pedagogical tools highlighted in the literature included tabletop exercises, safety huddles, trial runs for donning and doffing of new gear (with emphasis on air-fed suits), just-in-time training and virtual reality simulations.

Conclusions
Education on the effective use of PPE is essential to promote self-efficacy among medical staff and other first responders during nuclear radiological events. Comprehensive training will reduce unintended exposures, decrease hesitancy, and maximize employee safety.
Infringing AI: Liability for AI-Generated Outputs under International, EU, and UK Copyright Law
Authors: Rosati Eleonora 
Published: October 2024

Abstract
The analysis of liability aspects facing Artificial Intelligence (‘AI’)-generated outputs under copyright and related rights has been overlooked compared to other issues connected to the development and use of AI. This study fills this gap by exploring pertinent questions under international, EU and UK law. Specifically, the study tackles actionable reproduction, allocation of liability, and availability of defences. The analysis ultimately shows that, while it is clear that each case will need to be decided on its own merits, the generative AI output phase raises several profiles of liability under copyright law. If the goal of policymakers and relevant stakeholders is to ensure the balanced and sustainable development of AI, then the issues related to the generation and dissemination of AI outputs need to be given ample attention and a greater role in the debate than what has been the case so far, whether it is in the context of risk assessment and compliance, licensing initiatives, or in contentious scenarios.
Cattle Circulation, Beef Market Control Strategies, and African Agropastoralists in Southern Mozambique, 1900s–30s
Authors: Direito Bárbara 
Published: October 2024

AbstractFocusing on the first decades of the twentieth century but acknowledging longer-term patterns of circulation, this paper discusses how cattle, historically occupying important meanings and roles in the lives of African agropastoralists, was commodified and marketed in southern Mozambique just as Lourenço Marques became the new capital of Mozambique. Highlighting the relations that consolidated between the capital and surrounding cattle-rich areas in a period marked by cattle disease but also the First World War and the Great Depression, the paper looks at the role of different agents and bodies involved in the emerging beef market. Ultimately, the paper shows how African agropastoralists, the main cattle producers in the region, resisted these conditions and tried to engage with markets on their own terms, even in the face of their dwindling control over the different factors that influenced the size and quality of their herds.
Intellectual humility and Christian faith
Authors: Callahan Laura 
Published: October 2024

Abstract
Christians talk a lot about humility. They also talk a lot about the kinds of radical faith that seem to fly in the face of intellectual humility. I explore how best to resolve this tension, from a Christian perspective. I argue that rather than prohibiting radical, ‘all-in’ faith or giving up on an intellectual humility requirement, Christians should conceive of intellectual humility as rooted in (non-)concern for one’s intellectual ego. This kind of intellectual humility is compatible with radical faith, but it also suggests a critique of some actual, ego-driven faith commitments.

Published: October 2024

Summary
Reintroduction includes the captive propagation and movement of extirpated animals or plants into areas of historical and native distribution. Many biotic or abiotic factors can affect a founder population when small numbers are released into unfamiliar novel environments, particularly at the early stage of reintroduction. The inclusion of behavioural and ecological components plays a crucial role in the decision-making process of endangered species conservation efforts such as reintroduction. Since the resident population of Oriental Storks Ciconia boyciana was locally extirpated in South Korea in 1971, its founders have been established through reintroduction since 2015. The aim of this study was to investigate the demography, habitat use, and movement patterns of stork founders using the first two-year demographic and tracking data. Stork founders maintained their population size, which slightly increased in the long term. The patterns of habitat use and movement depended on rice paddy fields for foraging and breeding along with mixed effects of breeding status and season. Considering ecological and life history-related perspectives, we also discuss the potential adaptiveness of founder Oriental Storks as a resident population in a novel environment in South Korea.
Evaluating the application of front-of-package labelling regulations to menu labelling in the Canadian restaurant sector using menu food label information and price (Menu-FLIP) 2020 data
Authors: Jeong Hayun , Yang Yahan , Mulligan Christine , L’Abbé Mary R 
Published: October 2024

Abstract

Objective:
To evaluate the application of front-of-package (FOP) labelling regulations to menu labelling in the Canadian restaurant sector by assessing the proportion of menu items that would be required to display the ‘high-in’ FOP symbol if the policy were extended to the restaurant sector.

Design:
Nutrition information of 18 760 menu items was collected from 141 chain restaurants in Canada. Menu items were evaluated using the mandatory FOP labelling regulations promulgated in Canada Gazette II by Health Canada in July of 2022.

Setting:
Chain restaurants with ≥20 establishments in Canada.

Participants:
Canadian chain restaurant menu items including beverages, desserts, entrées, sides and starters.

Results:
Overall, 77 % of menu items in the Canadian restaurant sector would display a ‘high-in’ FOP symbol. Among these menu items, 43 % would display ‘high-in’ one nutrient, 54 % would display ‘high-in’ two and 3 % would display ‘high-in’ all three nutrients-of-concern. By nutrient, 52 % were ‘high-in’ sodium, and 24 and 47 % were ‘high-in’ total sugars and saturated fat, respectively.

Conclusions:
Given the poor nutritional quality of restaurant foods, the current regulations, if applied to restaurant foods, would result in most menu items displaying a FOP symbol. Therefore, expanding the Canadian FOP labelling regulations to the restaurant sector can be key to ensuring a healthy food environment for Canadians. Furthermore, menu labelling along with other multi-faceted approaches such as reformulation targets are necessary to improve the dietary intake of Canadians from restaurant foods.

Published: October 2024

Abstract

Aims:
We will examine the processes of change in psychological practice that have been altered by the lockdown.

Background:
During the COVID-19 pandemic, low-income populations, notably residents of social homes or shelters, were shown to be particularly susceptible to contagion. During lockdown, telephone-based psychological consultations became the norm.

Methods:
In this qualitative research, we carried out semi-structured interviews with 10 psychologists working in social homes or shelters. Interviews were transcribed verbatim. Data were studied using consensus qualitative research.

Findings:
During lockdown, participants felt that isolation increased while medical and social support decreased. Psychologists had to adapt their work methods and work more closely with on-site staffs. After lockdown, there was an increase in mental health issues. Participants perceived that telephone consulting seemed to facilitate access to psychological help. Although psychologists have quickly adapted, a decrease in the quality of clinical work was a general assessment. Results stress the necessity to train French psychologists in telemental health practices.
How the Struggle for Public Health in the Jim Crow South Reflected and Reinforced Systemic Racial Health Inequality
Authors: Elman Cheryl , Feltey Kathryn M. , Wittman Barbara , Stevens Corey , Hartsough Molly B. 
Published: October 2024

Abstract
The twenty-first century COVID-19 epidemic revealed a U.S. public health system that countenanced health inequities and a U.S. public that resisted disease containment policies. This crisis, however, was only the most recent chapter in a longer struggle in the United States to institutionalize public health. We focus on two early twentieth-century public health campaigns in the American South, the unhealthiest U.S. region at the time. Black southerners—denied basic health, political, economic, and social rights under a rising Jim Crow regime—self-organized health services networks, including through the Tuskegee Woman’s Club, the Negro Organization Society of Virginia, and the Moveable School (1890s–1915). Around the same time, a philanthropic project, the Rockefeller Sanitary Commission (RSC, 1909–1914), seeded state-level public health agencies in eleven southern states, thereby installing public health in a top-down manner. We use archival data sources to explore key similarities and differences in the public health concerns and coalition-building approaches of each campaign and southern resistance to their efforts. We find Black-led campaigns often blurred the color line to form coalitions that provided services to the underserved while tackling environmental health risks at the community level. In contrast, RSC affiliates in southern states, as directed by RSC administrators, provided health services as short-term public dispensaries. Services reached Black and White communities willing to participate but in a manner that did not overtly challenge Jim Crow-era practices. Southern resistance to public health expansion persisted under each approach. The legacies of these struggles remain; the political-economic and ideological forces that limited public health expansion while marginalizing Black community health efforts reverberate in public health inequities today.
Seed commodification and contestation in US farmer seed systems
Authors: Isbell Carina , Tobin Daniel , Mares Teresa , Jones Kristal 
Published: October 2024

Abstract
Over the last century seed systems have undergone a process of commercialization, resulting in the transformation of seed from a common good into a commodity. Countries such as the United States are dominated by the private seed industry, which has succeeded in reducing crop diversity and increasing farmer dependency on commodity seed (i.e., seed that is bought and sold) through such mechanisms as seed hybridization, intellectual property protections, and the proliferation of genetically engineered crop varieties. Commodity seed has become necessary to support food production, but concurrently has created a positive feedback loop that solidifies corporate control within the seed industry while concurrently disincentivizing traditional agricultural practices such as seed saving. In contestation, growers nationally and globally have called for change both within and outside of market structures – advocating for the revalorization of the vast array of social, cultural, and environmental benefits that seeds have that are not being properly protected by those with the most power in the seed industry. Using insight from 31 semi-structured interviews with growers involved in Vermont's farmer seed systems, this study elucidates some of the non-commodity values that growers hold for the seeds they source from both non-commercial and commercial sources. Our results highlight how growers appreciate such non-commodity values as provenance and diversity and are working to provide a social and environmental safeguard for seeds through seed saving. At the same time, many growers also acknowledge the convenience and modern necessity of commodity seed, highlighting the importance of supporting alternative seed industry structures that are more socially and environmentally responsible. These findings stress the importance of acknowledging the multidimensionality of US farmer seed systems, whereby market and non-market exchanges can coexist and work toward creating more just and sustainable seed systems without ceding to complete commodification devoid of social import.
Redefining the neutral intermediary role: Balancing theoretical ideas with practical realities through the ICRC's experience in Yemen
Authors: Stöcklin Diego 
Published: October 2024

Abstract
Neutrality, a foundational principle in humanitarian efforts and peace mediation, encounters significant practical challenges in the modern landscape of armed conflicts, particularly in the intermediary role of humanitarian organizations. This study examines the role of the International Committee of the Red Cross (ICRC) as a neutral intermediary in Yemen, focusing on the release and repatriation of detainees during the 2016–20 peace efforts. Drawing on the ICRC's experience, the analysis highlights the evolving understanding of neutrality from a rigid concept to a more flexible, context-sensitive approach. The findings emphasize the importance of neutrality in fostering trust and facilitating dialogue while acknowledging the operational complexities and strategic considerations involved. This study provides insights into enhancing the contributions of neutral intermediaries to sustainable peace processes.
