Distance education and parents’ mental health: the role of resilience, parent-child communication and relationships
Authors: Yang Zhixuan , Liu Meina
Published: June 2024

According to a UNESCO survey, 173 countries had closed schools and other educational facilities during the COVID-19 pandemic. As online distance learning became a new normal in disruptive times, researchers began to examine its psychological impact on parents and children. Drawing on Buzzanell’s (2010, 2018) communication theory of resilience, this study examined the relationships between Chinese parents’ resilience, their attitudes toward distance learning, parent-child communication and relationship, and psychological wellbeing. Participants were 101 Chinese parents who had children that did distance learning during the COVID-19 pandemic. Findings showed that parents’ resilience and attitudes toward distance learning had a positive, indirect effect on their psychological wellbeing through the mediation of parent-child communication and relationships. The study provides empirical support for the CTR theory as a fruitful lens for explaining family communication patterns and relationships, as well as psychological wellbeing during disruptive times. The study yielded important practical insights into how individuals can cope with the negative impact brought forth by unexpected and destructive events.
“I feel the weight of expectations”: how emotions and social norms shape news choices about superfood diets
Authors: Zeid Nour , Street Richard L. , Leiner Dominik J. , Scherr Sebastian
Published: June 2024

Focusing on “super diets” and different approaches to integrate superfoods in one’s diet (i.e., small- vs. large-change approaches), this study examines the drivers behind healthy eating information management (both seeking and avoidance). We combine self-reported data (N = 359) about the individual’s affective states (positive (PA), negative (NA), and mixed (MA)) and the perceived informational subjective norms (ISN) with unobtrusively measured news selectivity. The data was analyzed using zero-inflated negative binomial (ZINB) regression models, which simultaneously accounted for the seeking and avoiding healthy eating news. Findings revealed that the seeking behavior could neither be explained by the individual’s affective state (negative or mixed), informational subjective norms, nor by their interaction. However, contrary to our predictions, positive affect was not associated with avoiding news about healthy eating. Regarding specific content features, informational subjective norms were the only significant predictor of seeking news featuring large-change approaches to one’s diet. While individuals in negative affective states were likely to spend less time on news featuring a small-change approach, individuals with mixed affects were likely to spend more time on news featuring such an approach. The interaction between mixed affect and negative affect with informational subjective norms reversed this relationship. Theoretical and practical implications are discussed.
Balancing independence, collective interests, and media responsibilities: a framing analysis of COVID-19 coverage in the Sydney Morning Herald
Authors: Khan Mehwish Yaqoob , Martinez-Diaz Vivian A.
Published: June 2024

This study conducted a framing analysis of the Sydney Morning Herald’s media coverage during the COVID-19 pandemic in 2020 and 2021. Five main frames and themes were identified: (1) cases and numbers (e.g., active cases, recovered people, deaths, and tests), (2) awareness (of spread, prevention, treatment), (3) state policies, (4) collective interest and wellbeing, and (5) promotion of civic values. While all of these themes decreased in 2021 due to an overall decrease of reports in our sample (from 252 to 98 articles), the awareness frame increased, likely due to increasing coverage of vaccination awareness. In conclusion, the coverage of the pandemic reveals how the SMH prioritizes the Australian government’s interests in the control of the COVID-19 disease and how it promotes values of civility to protect human life. Since the SMH disseminates discourses that serve the interests of the Australian government, ethical principles of the media and journalism, such as independence, are compromised to promote civility that helps protect life.

Published: June 2024

Background and purpose: This study aims to assess time trends in case-mix and to evaluate the risk of revision and causes following primary THA, TKA, and UKA in private and public hospitals in the Netherlands.Methods: We retrospectively analyzed 476,312 primary arthroplasties (public: n = 413,560 and private n = 62,752) implanted between 2014 and 2023 using Dutch Arthroplasty Register data. We explored patient demographics, procedure details, trends over time, and revisions per hospital type. Adjusted revision risk was calculated for comparable subgroups (ASA I/II, age ≤ 75, BMI ≤ 30, osteoarthritis diagnosis, and moderate–high socioeconomic status (SES).Results: The volume of THAs and TKAs in private hospitals increased from 4% and 9% in 2014, to 18% and 21% in 2022. Patients in private hospitals were younger, had lower ASA classification, lower BMI, and higher SES compared with public hospital patients. In private hospitals, age and ASA II proportion increased over time. Multivariable Cox regression demonstrated a lower revision risk for primary THA (HR 0.7, CI 0.7–0.8), TKA (HR 0.8, CI 0.7–0.9), and UKA (HR 0.8, CI 0.7–0.9) in private hospitals. After initial arthroplasty in private hospitals, 49% of THA and 37% of TKA revisions were performed in public hospitals.Conclusion: Patients in private hospitals were younger, had lower ASA classification, lower BMI, and higher SES com­pared with public hospital patients. The number of arthroplasties increased in private hospitals, with a lower revision risk compared with public hospitals.
Random lasing using laser generated and modified silver nanoparticles
Authors: Salemi Luca , Compagnini Giuseppe
Published: June 2024

The authors report incoherent random laser action in systems where the optical feedback is provided by multiple scattering generated by different classes of silver nanoparticles in the colloidal state, having plasmon resonances at different frequencies. They found improved performance of triangular silver nanoplates as compared to nanospheres, with a threshold as low as 1 mJ/cm2 and a 5 times lower optimal silver concentration, due to plasmonic enhancement effects and tuning of the plasmon resonance. The nanoparticles were also tested for stability against illumination by the pump laser, as the onset of pulsed laser melting is comparable to random laser threshold in terms of pump fluence, severely limiting the range of operation of nanoparticles with main plasmon resonance close to the pump wavelength. The optimal approach to choose plasmonic nanoparticles for random lasing must, therefore, take the stability aspect into serious consideration as well as the plasmonic enhancement of random lasing.

teoria topológica da significação de René Thom e semiótica
Authors: Araujo Arthur
Published: June 2024

Este artigo representa uma segunda etapa da minha pesquisa sobre o trabalho do matemático francês René Thom. Foco principalmente em dois artigos da teoria dos signos de Thom: Do ícone ao símbolo (De l’icône au symbole), 1973 e O Espaço e os signos (L’espace et les signes), 1980b. Neste artigo, explorando a concepção topológica de significação de Thom, exponho sua ideia de que todas as formas de semiose (como processos de significado) desenvolvem uma forma espacial. É a partir do seu trabalho na reconstrução de formas globais na topologia que Thom define seu programa semiótico. Em particular, como mostrarei, Thom converte a classificação triádica de signos de Charles S. Peirce (ícones, índices e símbolos) em uma interpretação espaço-vetorial. Avançando meu estudo sobre a obra de René Thom (Araujo, 2022), exploro sua teoria topológica da significação segundo a qual a semiose pode ser entendida como um espaço topológico. Paralelamente ao seu trabalho sobre morfodinâmica em biologia, Thom redefine a dinâmica do signo, do objeto e do interpretante (segundo suas interconexões mútuas) que configuram topologicamente o próprio espaço da semiose.

Published: June 2024

O artigo tem como objetivo analisar os componentes curriculares do curso de Licenciatura em Matemática da Universidade Federal do Pará (UFPA) com vistas a promover uma reflexão sobre a contribuição das  disciplinas propostas no curso para a formação dos professores que irão atuar no Ensino Básico. A pesquisa adota a perspectiva qualitativa e as informações decorreram da pesquisa documental no Projeto Pedagógico do Curso (PPC) e das entrevistas realizadas com 13 (treze) discentes, a fim de investigar a perspectiva destes a respeito das disciplinas que contribuem e as que deixam possíveis lacunas para o fazer profissional do futuro docente. A fundamentação teórica tomou como base: Gonçalves (2000) e Fiorentini (2005) que fazem estudos significativos sobre formação de professores e as interações entre as disciplinas teóricas e didático-pedagógica nos cursos de Matemática. O estudo trouxe como resultados que o curso de Licenciatura em Matemática apresenta determinadas lacunas no que se refere a distribuição de carga horária entre as disciplinas teóricas (de Matemática específica e disciplinas pedagógicas) e disciplinas voltadas a prática como Estágios e Laboratórios, além dos professores do curso não promoverem reflexões e relações entre as disciplinas vistas na graduação e na Educação Básica. Neste sentido, após os 4 (quatro) anos na academia o futuro professor ao atuar no Ensino de Matemática na Educação Básica encontra lacunas deixadas pela formação, deixando de realizar reflexões sobre o Ensino e de desenvolver metodologias diferenciadas durante sua prática docente, as quais deveriam ser ensinadas e promovidas ao longo da formação inicial na Licenciatura em Matemática.

On the Peculiarities of Ventilation of Uranium Mines
Authors:   Moscow Polytechnic University, Golik V.I.
Published: June 2024

The systems of ventilation of radioactive deposits require special measures to minimize the impact of radon on miners. During the production of uranium ores, the working conditions of miners are determined by the content of metal in the broken ore, the intensity of radon emission, and the ventilation quality; therefore, the issues of mine atmosphere quality management become the top of the agenda. The patterns of gas interaction are found by modeling, with the determination of values of leaks through the exhaust space. The depth of regulation of air supply to the shaft bottom is determined as a function of regulation on the outgoing jet, the regime of airflow through the exhaust space, and the leak coefficient. A model of airflow in the direction of the shaft bottom has been compiled with the variables of the movement of ventilation jets. The pattern of airflow movement depending on the amount of air and the dimensions of the collapse area has been obtained. The mechanism to reduce contamination by using gas drainage through the collapsed wall has been identified. The recommendation on airing the mine workings with turbulent jets at a turbulent, laminar, and transient regime has been provided. A method to manage the atmosphere in the mine by adjusting the regime of leak movement through the mine working spaces has been recommended. The possibility of providing a mine with the required air by rationalizing the aerodynamic connection of mining operations with the surface has been substantiated. A practical issue of the airing of a section of an operating mine has been resolved as an example. It has been demonstrated that the substantiation of the possible use of isolated ventilation workings to release the contaminated air ensures cost savings due to the dismissal of a part of ventilation mine workings while ensuring the safety of miners. It has been proved that the possibilities of the injection method of ventilation increase when using an auxiliary drainage system.
On the Methodological Support for Improvement of the State Supervision over Industrial Safety Conditions at Objects of Mining, Metallurgical Productions, and Explosives in Use

Since the 2000s, the activities of the state supervision over industrial safety at hazardous production facilities of mining and metallurgical production in Russia have been reoriented. Fiscal methods in control and supervision practices are substituted with preventive measures, which outlines the development of new approaches to the supervision organization. The modern methodology aiming to improve the state mining supervision has been historically based on the Russian system of scientific and technical methods and organizational and administrative measures aiming at sustainable and long-term improvement of industrial safety level at hazardous production facilities of the Russian metallurgical and mining industry in conditions of internal production growth and external sanctions. The long-term experience of ensuring industrial safety at hazardous production facilities of the mining and metallurgical industry provides the key methodological ways to improve the state mining supervision: i.e., verification of reliability of identification of hazardous production facilities; broad public awareness of causes and consequences of accidents and occupational injuries and the necessary preventive measures; identification and elimination of intrasystem shortcomings in the control and supervision activities; updating and improving industrial safety norms and rules. The efficiency of such methods is tested with practical activities and the successful reduction of accident and injury rates at the facilities under supervision. The introduced mandatory requirements as defined based on the results of control and supervision activities and the analysis of accidents and fatal injuries as well as the strict compliance with such requirements have gradually led to the reduction of the accident and injuries level. This can be considered the main achievement of the methodological activity of the organization of the state supervision over the industrial safety condition at the facilities under the supervision. This also indicates the quality of the developed methods of the state supervision and their applicability for the further control, preventive, licensing and permitting, and normative activities. In recent years, new planning and checking methods based on indicators of risk of mandatory industrial safety requirements violation have been developed and implemented.

Industrial accidents and incidents are negative indices for the occupational safety management system of a company forcing employers to implement various systems of control and management of unsafe actions of employees. According to various studies, the human factor is the cause of the majority of accidents at production. Unintentional errors or negligent attitudes to work are the causes of unsafe actions of employees. Observation of the indices of unsafe actions of employees, identification of weaknesses, prediction of potential accidents, and the development of preventive measures are the basic factors to ensure occupational safety. In practice, however, the lack of necessary information hampers the implementation of timely preventive measures. Identification and study of unsafe actions of employees will provide the necessary basis for the analysis, prediction, and development of preventive measures to ensure occupational safety. The possibility to apply indices with fuzzy borders as preventive (leading) indicators to eliminate the causes of unsafe actions of employees has been demonstrated. Control and management of unsafe actions of employees based on fizzy indices will allow for the timely development of preventive measures to ensure occupational safety. Preventive indicators have been considered a database with fuzzy borders to rely on in order to develop measures to improve safety indices. The database will be changing constantly; therefore, the measures applied will be changing as well. This approach will stimulate the establishment of a positive safety culture in a company. The development and implementation of measures to improve indices of preventive indicators significantly increased safety indices in the company in 2023.

Social prescribing in Canada: health promotion in action, 50 years after the Lalonde report
Authors: Mulligan Kate , Card Kiffer G. , Allison Sandra
Published: June 2024

The Lalonde report, published in 1974 by the Canadian Minister of National Health and Welfare, broke ground for public health in Canada by acknowledging that the determinants of health are much broader than health care services. Fifty years later, this special issue of Health Promotion and Chronic Disease Prevention in Canada charts a clear path towards addressing upstream determinants of health through an emerging intervention called “social prescribing.” Social prescribing connects patients with community resources tailored to their individual priorities, fostering a paradigm shift from a deficitbased to a strengths-based approach in health promotion. Part 1 of this issue covers the rapid growth and diverse applications of social prescribing across Canada, with targeted initiatives for various populations and interventions ranging from nature and arts to physical activity and social connectivity. Contributions from a wide range of partners, including researchers, health professionals and community members, explore the adaptability of social prescribing for different groups, underscore the role of community and lived experiences in research, and call for more studies on social prescribing’s effectiveness and outcomes. Highlighted case studies demonstrate tangible benefits in health equity and access to social services.

How does fresh food prescribing fit into the social service landscape? A qualitative study in Ontario, Canada
Authors: Brubacher Laura Jane , Little Matthew , Richter Abby , Dodd Warren
Published: June 2024

Introduction

Food prescription programs are part of the broader social prescribing movement as an approach to address food insecurity and suboptimal diet in health care settings. These programs exist amid other social services, including income-based supports and food assistance programs; however, evaluations of the interactions between these programs and pre-existing services and supports are limited. This study was embedded within a larger evaluation of the 52-week Fresh Food Prescription (FFRx) program (April 2021–October 2022); the objective of this study was to examine how program participation influenced individuals’ interactions with existing income-based supports and food assistance programs.

Methods

This study was conducted in Guelph, Ontario, Canada. One-to-one (n = 23) and follow-up (n = 10) interviews were conducted to explore participants’ experiences with the program. Qualitative data were analyzed thematically using a constant comparative analysis.

Results

Participants described their experience with FFRx in relation to existing income-based supports and food assistance programs. FFRx reportedly extended income support further to cover living expenses, allowed participants to divert income to other necessities, and reduced the sacrifices required to meet basic needs. FFRx lessened the frequency of accessing other food assistance programs. Aspects of FFRx’s design (e.g. food delivery) shaped participant preferences in favour of FFRx over other food supports.

Conclusion

As food prescribing and other social prescribing programs continue to expand, there is a need to evaluate how these initiatives interact with pre-existing services and supports and shape the broader social service landscape.
Food prescribing in Canada: evidence, critiques and opportunities
Authors: Little Matthew , Dodd Warren , Brubacher Laura Jane , Richter Abby
Published: June 2024

Introduction

There is growing interest in food prescriptions, which leverage health care settings to provide patients access to healthy foods through vouchers or food boxes. In this commentary, we draw on our experiences and interest in food prescribing to provide a summary of the current evidence on this intervention model and critically assess its limitations and opportunities.

Rationale

Food insecurity is an important determinant of health and is associated with compromised dietary adequacy, higher rates of chronic diseases, and higher health service utilization and costs. Aligning with recent discourse on social prescribing and “food is medicine” approaches, food prescribing can empower health care providers to link patients with supports to improve food access and limit barriers to healthy diets. Food prescribing has been shown to improve fruit and vegetable intake and household food insecurity, although impacts on health outcomes are inconclusive. Research on food prescribing in the Canadian context is limited and there is a need to establish evidence of effectiveness and best practices.

Conclusion

As food prescribing continues to gain traction in Canada, there is a need to assess the effectiveness, cost-efficiency, limitations and potential paternalism of this intervention model. Further, it is necessary to assess how food prescribing fits into broader social welfare systems that aim to address the underlying determinants of food insecurity.

Benefits, barriers and willingness to pay for bike-sharing service in tourism context
Authors: Tru Vu Ngoc , Ngoc An Minh
Published: June 2024

This study explores benefits, barriers and willingness to pay for bike-sharing service in tourism context. Based on a sample of 800 individuals who visited Da Nang, Vietnam between July and August 2023, trends in the barriers and benefits related to bike-sharing service from tourists’ point-of-view were explored. The results show that bike-sharing is appreciated for many reasons, notably for its fun/relaxing, cost saving, ease of city exploration, and promotion of better physical and mental health. However, bike-sharing services are considerably less likely to be viewed as options for faster transportation to a destination or reducing traffic hazards. Notably, eighty-six percent of non-riders indicated contentment with their existing transportation options and a lack of interest in bike-sharing services, a proportion significantly higher than any other group. Predictably, barriers related to the availability of bike-sharing and infrastructure, such as lack of sufficient number of shared bikes, far destination, and poor road conditions were notably more likely to be selected by one-time riders. The results are also evident that a significant portion of tourists is willing to pay to enhance their tourist experience with a bike-sharing service. On average, tourists were willing to pay $0.92 per hour (with a standard deviation of $0.24). This amount reflects the tourists’ recognition of the value added to their mode experience. These findings suggest that bike-sharing service play a significant role in fulfilling an essential transportation niche and have the potential to contribute to enhance tourists’ experience. Efforts aimed at addressing barriers associated with bike-sharing usage could further enhance their contribution to improve tourist satisfaction and boost attraction demand.
An EEG-based Sleep Staging method with hybrid entropy computation measures
Authors: Yang Yiqian , Fu Shuchen , Liao Ruixiang
Published: June 2024

Sleep is an indispensable physiological need of the human body. Sleep staging is an effective method to objectively assess sleep quality and is helpful for research on sleep and sleep-related diseases. Electroencephalogram (EEG) signals are nonlinear and non-stationary time series, and entropy features are particularly sensitive to these nonlinear characteristics and can reveal information that is difficult to discover with traditional linear analysis methods. We proposed an automatic sleep staging method based on EEG entropy computation, inlcuding signal preprocessing, entropy feature extraction, feature selection and lassification modules. The experimental results show that the average accruacy is 91.3% through the fused entropy features.
