During the first wave of the COVID-19 pandemic, immigrants were among the most socially vulnerable in Western countries. The Chinese diaspora in Canada were one such group due to the widespread cultural stigma surrounding their purported greater susceptibility to transmit and become infected by COVID-19. This paper aims to understand the social vulnerability of the Chinese diaspora in the Greater Toronto Area, Canada, during the first wave of COVID-19 from an explanation of their risk perception and threat appraisal of risk communication. We conducted secondary data analysis of 36 interviews using critical realism. The participants self-identified as being of Chinese descent. The results were used to develop a model of how social vulnerability occurred. In brief, cognitive dissonance was discovered to generate conflicts of one's cultural identity, shaped by social structures of (i) stigma of contagion, (ii) ethnic stigma, and (iii) public sentiment, and mediated by participants' threat appraisal and (iv) self-reliance. We assert that risk communicators need to consider their audiences' diverse socialization in crafting messages to modify behaviors, create a sense of responsibility, and mitigate public health threats. A lack of awareness of one's cognitive dissonance driven by cultural vulnerability may heighten their social vulnerability and prevent them from taking action to protect themself from high-risk events.

Objective: Clarifying the distinctions between art-based creative activities in the domains of occupational therapy and art therapy in the context of stroke rehabilitation, while also describing the effects of art-based creative activities on stroke rehabilitation. Design: Scoping review. Data source: A systematic search was performed in nine databases (Web of Science, PubMed, EMBASE, Cochrane Library, CINAHL and four Chinese database) from their inception to December 2023. Review methods: The study included randomized and non-randomized controlled trials involving art-based creative activities, as well as qualitative research providing detailed intervention measures. The study focused on stroke patients, with primary outcomes related to patients' physiological recovery, psychological well-being, ADL, etc. Data extraction included information on intervention strategies and study results. Results: Seventeen studies were included, extracting six similarities and differences in creative activity between two domains. Creative activities were observed to have positive impacts on daily living activities, limb motor function, fine motor ability, and emotional well-being in stroke patients. Conclusion: Creative activities, whether in occupational therapy or art therapy, involve providing participants with tangible crafting materials for the creation of artistic works. Future stroke rehabilitation practices should tailor activities and intervention focus based on patients' rehabilitation needs, preferences, and cultural background. The current comprehensive analysis provides initial support for the potential positive role of creative activities in stroke rehabilitation, but further in-depth research is needed to confirm their effectiveness.

Although scholars have researched Chinese parents' perspectives on play pedagogy, few investigate the differences between parents of preschoolers and early primary schoolers, non-immigrant and immigrant parents. The present study employs the theoretical framework of parental ethnotheories to describe parental understanding and concerns about the use of play in supporting young children's English learning in China. The nine participants included parents of preschoolers and/or primary schoolers who were non-immigrant and immigrant Chinese parents in Canada. Findings revealed different types of discrepancies concerning parental beliefs and practices. First, there was a gap between parents' beliefs and their practices regarding child-rearing and education. Second, in terms of understanding play, Chinese parents held a slightly different perspective compared to that of western parents in other studies, showing that Chinese parents only valued play's supporting role in the development of non-cognitive aspects, such as improving interest in learning English. Third, parents of preschoolers and early primary schoolers held conflicting attitudes toward the use of play in children's learning. Fourth, immigrant Chinese parents were inclined to follow traditional Chinese notions of child-rearing, revealing discrepant perceptions about child play and rearing compared to western knowing of child-rearing in previous studies. The findings raise implications for educators to balance the pedagogical perspectives of child development and parental ethnotheories of child development. [ABSTRACT FROM AUTHOR]

Staphylococcus aureus sequence type (ST) 398 is a lineage affecting both humans and livestock worldwide. However, the mechanisms underlying its clonal evolution are still not clearly elucidated. We applied whole-genome sequencing (WGS) typing to 45 S. aureus strains from China and Canada between 2005 and 2014, in order to gain insight into their evolutionary pathway. Based on WGS phylogenetic analysis, 42 isolates were assigned to the human-associated clade (I/II-GOI) and 3 isolates to livestock-associated clade (IIa). Phylogeny of ϕSa3 sequences revealed five phage groups (Groups 1–5), with Group 1 carrying ϕSa3-Group 1 (ϕSa3-G1), Group 2 carrying ϕSa3-G2, Group 3 carrying ϕSa3-G3, Group 4 carrying ϕSa3-G4 and Group 5 lacking ϕSa3. ϕSa3-G1 was only found in strains that accounted for the most ancestral human clade I, while ϕSa3-G2, ϕSa3-G3 and ϕSa3-G4 were found restricted to sublineages within clade II-GOI. Some isolates of clade II-GOI were also found to be ϕSa3-negative or resistant to methicillin which are unusual characteristics for human-adapted isolates. This study demonstrated a strong association between phylogenetic grouping and phage type, suggesting an important role of ϕSa3 prophage in the evolution of human-adapted ST398 subclones. In addition, our results suggest that this subclone slowly began to adapt to animal hosts by losing ϕSa3 and acquiring methicillin resistance, which was observed in some strains of human-associated clade II-GOI, an intermediate human to livestock transmission clade.

Prediction of renewable energy consumption structure (RECS) can provide important guidance for energy development planning and energy structure transformation. The RECS refer to the proportion of various renewable energy consumptions and belong to compositional data, which could reflect the structural shapes of a complete system better. The multivariate compositional data's vector autoregressive model (CDVAR) on the basis of the Simplex space and its algebraic system is proposed in this study aiming at the multi-dimensional small sample size. Firstly, the algebraic system of the Simplex space is introduced and the statistics of the compositional data are defined. Secondly, the novel model with the form of the compositional data is obtained and the least square parameter estimation of the model is derived according to Aitchison geometry. Third, the validation of the novel model is verified by the data on RECS in countries (China, USA, and Canada). The validation presents that the proposed model performs better in fitting, prediction, stability, and applicability compared with other five models under transformation. Last, the proposed model is applied to analyze and forecast the RECS of the above countries in 2021–2025 to provide an important basis for the optimization of the RECS. [ABSTRACT FROM AUTHOR]

Due to cultural and systemic factors, Chinese-Canadians tend to use mental health services less or when mental health problems are more severe. Services need to be more culturally responsive in their treatment of mental illness. Around important life events, when there may be heightened vulnerability to mental illness, this is especially important. In this study, postpartum cultural practices were examined among recent immigrant, longer-term immigrant, and Canadian-born Chinese women. We conducted a longitudinal cohort study of 493 women in Toronto, Ontario, with livebirths in 2011–2014. Participants completed a demographic survey and Postpartum Rituals Questionnaire. Most women (82.2%) practiced at least one postpartum ritual. Younger age (OR 0.93; 95% CI 0.87–0.99) and greater participation in the heritage culture (OR 1.28; 95% CI 1.02–1.61) were associated with ritual practice. From among five types of postpartum rituals identified (i.e., avoidance of homeostatic disturbances, dietary practices, wind avoidance, organized support, and cold avoidance), dietary practices were most commonly undertaken and cold avoidance was least commonly undertaken. There were differences in postpartum ritual patterns by immigration status, with immigrant women being more likely to undertake a greater number of rituals, to attribute these rituals to Chinese culture, and to ascribe health benefits to these rituals and being less likely to feel forced into performing these rituals. Our findings underscore the importance of clinicians becoming more aware of Chinese postpartum rituals to provide women with culturally competent and patient-centered care. [ABSTRACT FROM AUTHOR]

Although concepts such as research without borders have become more commonplace in recent decades, few studies have investigated the capabilities that global researchers require to cross both cultural and disciplinary borders. This paper explores global capabilities along with strategies and spaces that may facilitate academic researchers' acquisition and development of global research competence. The study's dataset comprises responses of 26 participants across 15 countries -- all of whom are members of a specific comparative education society -- who contributed their views via e-questionnaire. Findings indicate that research capacity building is a dynamic process and global competence calls for complex skills and conscious attitudes. Commitment to expand scientific curiosity beyond one's own culture and academic discipline appears to be a main criterion in achieving global competence. Results of this study are not meant to be prescriptive but rather exploratory and informative for a broad group of academic stakeholders.

Purpose: Microteaching is a teacher training method based on microclasses (groups of four or five students) and microlessons lasting no more than 5-20 min. Since it was first explored in the late 20th century in experiments at Stanford University, microteaching has evolved at the interdisciplinary level. The purpose of this paper is to examine the networks found via an analytical bibliometric study of the scientific output related with microteaching in teacher training, through a study and examination of the Web of Science database. Design/methodology/approach: This research was conducted with the VOSviewer tool for content analysis through data mining and scientific network structure mapping by means of the normalisation technique. This technique is based on the association strength indicator, which is interpreted as a measurement of the similarity of the units of analysis. Findings: Two hundred and nine articles were thus obtained from the Web of Science database. The networks generated and the connections among the various items, co-authorship and co-citation are presented in the results, which clearly indicates that there are significant authors and institutions in the field of microteaching. The largest cluster is made up of institutions such as Australian Catholic University. The most often-cited document is by Rich and Hannafin. Allen (1968), who defines microteaching as a technique based on microclasses and microlessons, is the author most often cited and has the largest number of connections. Research limitations/implications: This research's limitations concern either aspects that lie beyond the study's possibilities or goals that have proved unattainable. The second perspective, which focuses on skill transfer, contains a lower percentage of documents and therefore has a weaker central documentary structure. Lastly, the authors have also had to bear in mind the fact that the scientific output hinges upon a highly specific realm, the appearance and/or liberalisation of digital technologies and access to those technologies in the late 20th century. Originality/value: This research shows that microteaching is a promising area of research that opens up vast possibilities in higher education teacher training for application in the realm of technologies. This paper could lead to several lines of future research, such as access to and the universal design of learning from the standpoint of different communication and pedagogical models based on microteaching.

Teaching quality assurance has become a common concern and a common pursuit for institutions of higher learning around the world. This paper takes teaching quality as a governance issue in higher education, as different governance systems entail different approaches to quality assurance. Through a detailed examination of the Chinese system in teaching administration in comparison with the Canadian system, this study aims to provide insights on different approaches to teaching quality assurance in more centralised and decentralised governance structures. Based on the findings of this study, no winner can be declared between centralised and decentralised systems in the area of teaching quality assurance. Instead, the study points to different strengths in each system. With more local autonomy, the decentralised system better respects disciplinary uniqueness and academic freedom in teaching. With more national planning, the centralised system secures a system-wide threshold in teaching quality and an optimal long-term development.

As humanity reaches the 5.0 industrial revolution, education plays a critical role in boosting the quality of human resources. This paper reports bibliometric research on emerging TiP during 1993-2022 in the educational field to analyse its development on any level of education during the last three decades. This study employed a Scopus database. The findings are that the trend of TiP publication in educational fields has tended to increase every year during the past three decades and conference paper became the most published document type, the USA is the country which produces the most publications; "Students" being the most occurrences keyword and total link strength. The publication of the TiP is ranked to the Quartile 1, which implies that a publication with the cited performance is a publication with credibility because the publisher has a good reputation. Researchers can find the topics most relevant to other metadata sources such as Web of Science, Publish, and Perish.

Introduction/Objective Advance Care Planning (ACP) discussions are infrequently conducted with physicians, even fewer among minorities. We explored physicians' experiences in engaging Chinese (CH) and South Asian (SA) patients in ACP conversations to understand initiation and participation patterns, topics covered, and barriers and facilitating factors. Method Twenty-two physicians with 15%+ SA patients aged 55+ and 19 with 15%+ CH patients aged 55+ were interviewed. Results SA- and CH-serving physicians described similar initiation patterns, cultural context, and need for standardized ACP routines. However, the SA-serving physicians described greater involvement of family members, while CH-serving physicians described more communication barriers and family members' desire to hide the diagnosis from patients. Conclusion Cultural taboos surrounding discussion around death and dying appear to influence CH older adults and families strongly. Lack of familiarity with ACP amongst the SA population accounts more for their limited engagement in ACP discussions. [ABSTRACT FROM AUTHOR]

While coparenting-related conceptual frameworks and empirical studies have received considerable attention in Western countries, there is far less attention on this topic in other regions. This study seeks to fill this gap by comparing coparenting dynamics between English-speaking and Chinese parents. This study begins by reviewing coparenting relationships in both Western and Chinese contexts. Study participants comprised 399 English-speaking parents living in the US and Canada and 534 Chinese parents living in Mainland China. There were several waves of participant recruitment by sending out the flyers online or utilizing the professional networks to invite eligible parents. The measurement tool CoPAFS (Coparenting across Family Structures), which has been validated in English-speaking culture, was used to compare the differences in coparenting constructs in two cultures. First, the model fit of CoPAFS within Chinese culture was examined with Cronbach Alpha values and relevant model fit indices such as Comparative Fit Index and Root Mean square Residual. As most of the statistics fell below the expected level of excellence, there is a need to locally adjust the entire model in order to better interpret Chinese parenting. The intensity of connection between each factor included in the model and the coparenting relationship as a whole was then investigated. Although most factors were endorsed similarly by Chinese and English-speaking parents, there were notable differences in their opinions regarding communication and trust. While English-speaking parents highly valued these two elements within the coparenting process, Chinese parents showed almost no attentiveness to them. In order to understand factors that may contribute to such a sharp contrast, two main variables, culture and gender, were tested. Through a series of multigroup invariance analyses assessing equivalence across groups, it was discovered that culture emerged as the more dominant determinant among the groups of participants. The implications of cross-cultural use of the CoPAFS tool and future research directions are discussed. [ABSTRACT FROM AUTHOR]

In a series of two papers, the narrative themes of Intergenerational Trauma (IGT) from both the parent and offspring generation in the Chinese diaspora in Canada are examined. This paper focuses on the experiences of parental participants and their perspectives on how trauma transmits to the next generation. Narratives of IGT from three participants were co-constructed using the Collaborative Narrative Method. The narratives were largely situated during pre-migration in China, with most traumatic experiences related to sociopolitical events between the 1950s to 1980s. Themes were developed from the narratives using reflexive thematic analysis. These themes include the following: (a) decimation of social structures; (b) oppression, chaos, and abuse; (c) desperation for survival; (d) personal losses and the denial of education and opportunities; and (e) preservation of values. Themes associated with participant perception of how their traumatic experience transmitted to their offspring, include the following: (a) desire for stability and opportunities; (b) pressure and concern for the future of their offspring; and (c) hope for the future. The study has implications for understanding the linkage between historical events and individual narratives in the Chinese diaspora, as well as the study of IGT among Chinese populations and their narratival understandings.

The legalization of recreational cannabis consumption in Canada created a cultural conflict for international students from China, where the use of cannabis is heavily criminalized and deemed immoral. This conceptual paper theorizes this cultural conflict experienced by Chinese international students in Canada by applying three theories from macro to micro levels. Neoliberalism is first used to understand how this cultural conflict exposes collisions between the neoliberal West and the rising economic power of China as illustrated through Chinese students studying in Canada. Next, acculturation theory focuses on these students' cultural transition and provides further insight into potential strategies for their handling of specific cultural conflicts such as cannabis use. Lastly, Cloninger's theory of substance use is adopted to explore Chinese international students' individual reasoning about cannabis use, particularly how they make decisions based on evaluations of various conditions. Building upon the above analyses, an integrated conceptual model is further formed to help us understand Chinese students' potential perception of cannabis use in Canada. This conceptual framework provides an important theoretical and conceptual base for future research and practice, from which to further explore cannabis use in the context of cultural transition of different immigrant and migrant groups.

This study examines through a systematic review, the reference services rendered in academic libraries using artificial intelligence (AI) and by collecting data through environmental scanning. The objective of this systematic literature review is to provide a synthesis of empirical studies exploring the application of artificial intelligence for reference services in academic libraries. Data were collected from Web of Science, Scopus, and LISA databases. Following the rigorous/established selection process, a total of thirty five articles were finally selected, reviewed and analyzed. Thirty five papers were identified, analyzed and summarized on the subject relating to the application of AI and the methods which are most often used. The findings demonstrate that university libraries in Canada and China are leading in the deployment of AI for reference services. The AI techniques used mostly in the scanned university libraries are self-directed learning and natural language processing techniques; while the challenges of using AI for reference services are the problem of quality intelligence, linguistic style, privacy, a threat to intellectual freedom, bias, and cost; inadequate experts, poor network, poor training and lack of innovation, and limited knowledge about the technology. The study indicates university libraries take into account implementing AI for reference services. [ABSTRACT FROM AUTHOR]

This paper presents findings from an investigation of nature-based practices, from the perspectives of 10 academics/educators from six nations. Participants engaged in a focus group exploring the prevalence and inclusion of nature in social work practice and education. While the study focused on individual members' experiences and perspectives, the findings highlight important context-specific factors for including nature within social work to reconnect humans with nature for health, well-being, healing, and justice. An Integrative Environmental Model for social work is proposed to assist future practice and education. [ABSTRACT FROM AUTHOR]

Background: Infection prevention competencies are critical for successful job performance, career progression and robust performance of infection prevention and control programs. Aim/objective: Identify competency assessment tools available to infection preventionists and describe their characteristics, validation processes and reliability. Methods: A scoping review was conducted on five databases and grey literature from 1999 to 2022. A descriptive synthesis approach was undertaken to analyse the data. Finding/results: Seven tools that meet the inclusion criteria were identified. Of those, one tool was reviewed twice. All tools were developed in the United Kingdom, Canada, China and the United States, and were published between 2009 and 2022. All tools use a rating scale; and the most used method to assess competencies was self-assessment. Levels of competency were cited by five tools. Two tools provided information on validation methods and reliability tests for internal consistency. Discussion: Few competency assessment tools are available in the literature, and there is a lack of information on their development process. A global effort to develop an assessment tool that allows comparison across countries and cultures can be a step forward to propel infection preventionists' careers and enhance the efficacy of Infection Prevention and Control Programs.

Research has explored age-related and cultural differences in moral evaluations of dishonesty; however, this has not yet been examined in an aging context. The present study provided a novel account of how younger and older adults (in Canada, Singapore, and China; N = 401) morally evaluate adults' truths and lies in antisocial, modesty, and politeness settings. Participants completed a questionnaire assessing how acceptable it is for adults to tell the truth or a lie in given social scenarios, and they reported on their levels of collectivism and individualism. In all countries, older adults provided more favorable evaluations to blunt and immodest truths than younger adults did. Compared with younger adults, older adults provided harsher evaluations to Polite Lies (in Canada and China) and Modesty Lies (in Canada and Singapore). Thus, there may be an age-related increase in the acceptability of direct honesty over good-intentioned lies, and this age effect is somewhat stable across cultures. Older adults were also more lenient in evaluations of an antisocial lie to conceal an affair compared to younger adults. Overall, adults in China tended to rate lies less negatively, and their greater levels of collectivism mediated their greater approval of polite lies. The present results demonstrate that evaluations of (dis)honesty differ as a function of age and culture and these results can assist in developing a more complete lifespan model of the morality of dishonesty.

Existing literature on international health partnerships is largely normative, with an evaluative interest in their impacts in terms of learning and knowledge transfer. Rarely has research attended to how learning and knowledge transfer transpire in practice. This paper addresses this gap with a case study of a partnership between two hospitals in Canada and China. Conceptually, drawing on Actor Network Theory, it posits learning and knowledge transfer as a process of translation. Empirically, it traces the assembling of the programme, and identifies the pedagogical features at nodes of associations. It reveals that health professionals in both countries have expanded their clinical and medical knowledge and practices, and professional senses and sensitivities, which were subsequently amplified, deferred or diminished within their respective practices. It argues that the capacity of individuals to translate learning into practice is contingent on institutional and cultural differences that constitute the ecology of work for health professionals.

• Develops a structure-agency analytical framework to examine the trajectories of emerging technologies in different national contexts. • Compares AI development and diffusion between a developed country and an emerging country based on 125 in-depth interviews. • Argues that the levels of institutionalisation exert different structural forces and leave different spaces for institutional work. • Yields practical implications for developing countries to address the trade-off between the opportunities and risks brought by emerging technologies. Development studies have paid less attention to the role of technological innovations and we are yet to understand how, and more importantly why, technological trajectories differ across countries. This gap becomes sharper as emerging technologies such as artificial intelligence (AI) are becoming increasingly important in addressing many world development challenges. Drawing on insights from institutional work literature, this paper develops a structure-agency interplay framework to unravel the various trajectories of emerging technologies at the national level and examines the development and diffusion of AI in Canada and China. The findings show that Canada's stable institutional environment, reinforced through institutional work by various actors, generated a national AI trajectory driven by technology development through a strong focus on scientific research and ethics, with slower organic commercialisation of AI. In China, a dynamic and loose institutional structure characterised by lax regulations, low entry barriers, and high openness to novelties has resulted in a market-driven AI trajectory focused on technology commercialisation, with domestic digital giants and the government as dominant players. National-level dynamics in formal institutions, informal institutions, technologies, and actor strategies determine heterogeneous approaches to technology development and diffusion, giving rise to varieties of technological trajectories. The levels of institutionalisation exert different forces and create different spaces for institutional work across different geographical contexts. [ABSTRACT FROM AUTHOR]

Objective: This meta‐analysis aimed to determine the effect of mindfulness interventions on nurses' levels of depression and anxiety. Design: Meta‐analysis of randomised controlled trials. Methods: The following Chinese and English databases were searched: PubMed, Embase, Cochrane Library, Web of Science, and China National Knowledge Internet (CNKI). The retrieval period was from database construction to 30 March 2022. Two researchers screened the relevant literature and extracted the data. After a cross‐check, data were input into Stata version 16.0 for meta‐analysis. Results: Twelve randomised controlled trials from 2017 to 2021 were included, which involved 807 subjects (405 and 402 in the intervention and control groups, respectively). Meta‐analysis results showed that nurses' anxiety reduced by mindfulness‐based interventions was significantly higher compared to that of the control group (SMD = 0.91, 95% CI: 0.27–1.55, p < 0.05). Furthermore, an 8‐week mindfulness‐based intervention (SMD = 1.43, 95% CI: 0.61–2.24) reduced the level of anxiety significantly more compared to a 4‐week intervention (SMD = 1.03, 95% CI: 0.36–1.71). Mindfulness‐based interventions were better compared to conventional intervention to reduce the level of depression (SMD = 1.02, 95% CI: 0.42–1.61, p < 0.05), and an 8‐week mindfulness intervention (SMD = 1.81, 95% CI: 0.78–2.84) reduced the level of depression significantly more compared to a 4‐week intervention (SMD = 0.82, 95% CI: 0.29–1.35). Since limited studies had interventions longer than 8 weeks, results on longer mindfulness interventions in reducing nurses' anxiety and depression are inconclusive. In conclusion, mindfulness intervention for 8 weeks or less can significantly reduce nurses' anxiety and depression levels. Patient or Public Contribution: None. [ABSTRACT FROM AUTHOR]

This paper analyzes the risk-return characteristics of socially responsible investing by employing a time-varying capital gain and Sharpe ratio analysis for various investment horizons. We employ the MSCI ESG (environmental, social and governance) leaders indices in ten markets encompassing Australia, Canada, Europe, Japan, UK, USA, China, India, Russia, and South Africa. Our sample ranges from 2007-2020. We document that ESG investments have very desirable return and hedging attributes for investors in these markets, and especially so in the USA and emerging markets., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Gubareva et al.

Purpose: The purpose of the study is to show that divergent perceptions among regulators, the regulated and the associated regulatory bodies across multiple jurisdictions regarding the nature and functionality of cryptocurrencies hamper the development of a more comprehensive and coherent regulatory framework in curbing crimes and other related risks associated with cryptocurrencies. Design/methodology/approach: The study has used a descriptive doctrinal legal research method to investigate and understand the insights of existing laws and regulations in four selected jurisdictions concerning cryptocurrencies and how these laws could be further improved and developed to reduce crypto-related crimes. Furthermore, the study has also used a comparative research method to conceptualize the contours of the new legal discourse emerging from cryptocurrencies to adopt and implement a sound regulatory framework. Findings: The study illustrated that divergent regulatory treatment among different jurisdictions might suffocate novel digital innovations such as cryptocurrency. These fragmented regulatory approaches by various jurisdictions question the sustainability of the present national legislation adopted to regulate cryptocurrencies. Looking into other jurisdictional developments in regulating cryptocurrencies, it is apparent that a concerted regulatory approach is needed to minimize the abuse of this innovation. Research limitations/implications: The study has implications for regulators and policymakers to review the current regulatory framework for regulating cryptocurrencies to prevent regulatory arbitrage. The divergent legislative measures concerning cryptocurrency among different jurisdictions question the sustainability of these legislative initiatives, considering the evolving and borderless nature of cryptocurrency. Therefore, this paper will help regulators to consider the present legislative gaps in establishing a common global regulatory approach in the crypto sphere. Originality/value: The study contributes to the existing body of literature by examining the regulatory frameworks of four jurisdictions, namely, the USA, Canada, China and the EU, related to cryptocurrencies, with a discussion on the development of cryptocurrencies-related laws among these four jurisdictions and their sustainability in curbing crimes in the Darknet.

Volatile organic compounds (VOCs) in urban areas are of great interest due to their significant role in forming ground-level ozone and adverse public health effects. Emission inventories usually compile the outdoor VOCs emission sources (e.g., traffic and industrial emissions). However, considering emissions from volatile chemical products (e.g., solvents, printing ink, personal care products) is challenging because of scattered data and the lack of an effective method to estimate the VOCs emission rate from these chemical products. This paper aims to systematically analyse potential sources of VOCs emission in Canada's built environment, including volatile chemical products. Also, spatial variation of VOCs level in the ambient atmosphere is examined to understand the VOC relationship with ozone and secondary organic aerosol formation. The study shows that VOCs level may vary among everyday microenvironments (e.g., residential areas, offices, and retail stores) depending on the frequency of product consumption, building age, ventilation condition, and background ambient concentration in the atmosphere. However, it is very difficult to establish VOC speciation and apportionment to different volatile chemical products that contribute most significantly to exposure and target subpopulations with elevated levels. Thus, tracer compounds can be used to identify inventory sources at the consumer end. A critical overview highlights the limitations of existing VOC estimation methods and possible approaches to control VOC emissions. The findings provide crucial information to establish an emission inventory framework for volatile chemical products at a national scale and enable policymakers to limit VOCs emission from various volatile chemical products., (© 2022.

Bisphenol A (BPA) is mainly used to produce polycarbonate consumer products. However, the occurrence of BPA and other bisphenol analogues (BPs) in polystyrene-made plastic products, such as white foam take-out containers (WFTOCs), has not been well investigated. In this study, occurrence of 20 BPs in WFTOC samples collected from China, Canada, and Poland were investigated with a sample size of 152. Results showed that 11 out of 20 BPs have been detected at least in one WFTOC sample. Among them, BPA was the most frequently detected BP, followed by bisphenol S (BPS) and bisphenol AF, while BPF was the least detected BP. Very high concentrations of BPA and BPS were detected in WFTOCs from China (mean 2694 and 552 ng/g), compared with Canada (81 and 45 ng/g, respectively) and Poland (95 and 16 ng/g). Other BPs, such as bisphenol TMC (BPTMC; detection frequency 65%, range < LOQ − 224 ng/g), bisphenol G (17%, < LOQ − 11 ng/g), and bisphenol BP (11%, < LOQ − 1.6 ng/g), were also detected in Chinese WFTOC samples. The mean partitioning coefficients of BPA, BPS, bisphenol AP, and BPTMC between WFTOCs and tap water, 10% ethanol, 50% ethanol, corn oil, or steamed rice were 0.22 − 2.9%, 0.16 − 5.1%, 0.11 − 7.5%, 2.3 − 6.5%, or 0.19 − 0.36%, respectively. The estimated daily intake of BPA, BPS, and BPTMC through using WFTOCs were 0.50 − 547, 0.054 − 229, and < 0.66 ng/kg bw/day, respectively, for general population in China, Canada, and Poland. Overall, this study first reveals the unexpected presence of BPs in WFTOCs made of polystyrene, which contributes to the better understanding of the sources of human exposure to BPs.

As deforestation has become an increasingly urgent issue worldwide, global initiatives and national policies have been launched to reduce deforestation. However, existing measures pay little attention to indirect deforestation and consumers' responsibilities, overlooking the different roles played by countries in the trading network. Therewith, to identify the producer's and consumers' responsibilities for deforestation, and reveal the roles and interrelations of those countries in the trading system, this study applies input-output analysis to find the main producers and consumers of embodied deforestation and complex network method to construct a network to illustrate the interrelations of the countries and identify their roles in the network. The results show the United States, China, Germany and other developed countries are the main consumers while Canada, Brazil, Indonesia and other heavily forested countries are the critical providers of embodied deforestation. Further studies find these countries have the highest level of degree, strength, and centrality, dominating the trade activities in the network. Additionally, the network features small-world nature and heterogeneity, illustrating the close connection of the network and the decisive roles of key nodes. This analysis provides findings to help policymakers more effectively address deforestation worldwide, by highlighting the flow of resources to and from key economies which have previously been overlooked., 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 © 2022 Elsevier Ltd.

While ChatGPT has recently become very popular, AI has a long history and philosophy. This paper intends to explore the promises and pitfalls of the Generative Pre-trained Transformer (GPT) AI and potentially future technologies by adopting a speculative methodology. Speculative future narratives with a specific focus on educational contexts are provided in an attempt to identify emerging themes and discuss their implications for education in the 21st century. Affordances of (using) AI in Education (AIEd) and possible adverse effects are identified and discussed which emerge from the narratives. It is argued that now is the best of times to define human vs AI contribution to education because AI can accomplish more and more educational activities that used to be the prerogative of human educators. Therefore, it is imperative to rethink the respective roles of technology and human educators in education with a future-oriented mindset.

Existing literature on international health partnerships is largely normative, with an evaluative interest in their impacts in terms of learning and knowledge transfer. Rarely has research attended to how learning and knowledge transfer transpire in practice. This paper addresses this gap with a case study of a partnership between two hospitals in Canada and China. Conceptually, drawing on Actor Network Theory, it posits learning and knowledge transfer as a process of translation. Empirically, it traces the assembling of the programme, and identifies the pedagogical features at nodes of associations. It reveals that health professionals in both countries have expanded their clinical and medical knowledge and practices, and professional senses and sensitivities, which were subsequently amplified, deferred or diminished within their respective practices. It argues that the capacity of individuals to translate learning into practice is contingent on institutional and cultural differences that constitute the ecology of work for health professionals.

Objective: Schools are important settings for health promotion. In schools, children and adolescents can be reached regardless of their social background, which represents a unique opportunity for promoting health. Several studies have demonstrated the importance of school leadership in initiating and sustaining health promotion; however, efforts to systematically review the influence of school leadership on school health promotion are still lacking. Hence, this paper analyses empirical studies published in scientific journals on school leadership and health promotion in schools. Design: Systematic literature review. Method: Informed by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, a review was conducted using two main databases: Web of Science and Scopus, which retrieved 51 eligible articles. Results: The review of these articles resulted in the identification of seven main themes -- school leaders' health; attitudes, knowledge and behaviour; accountability; support from school leaders; shared leadership approaches; capacity building and parent engagement. Conclusion: This systematic literature review expands the literature by highlighting the school leadership factors that promote school health promotion in Oceania, Europe, North America, South America, Africa and Asia continents. Future systematic literature reviews could explore studies and different aspects of health promotion by teachers, especially in the Asian context.

Background Generic drugs have been seen as a potentially powerful way to alleviate the financial burden on patients and health care systems. Two strategies for achieving rational prices of generic drugs are tiered pricing framework and pooled purchasing power. We compare the pan-Canadian Tiered Pricing Framework (TPF) and the Chinese National Volume-Based Procurement (NVBP) as comparators to explore the similarities and differences between the two mechanisms and summarise lessons for other jurisdictions. Methods This comparative study applies Donabedian's structure-process-outcome framework to systematically analyse the macro contexts, procedures, and long- and short-term results of each pricing mechanism, and the interactions between them. Results Structure: TPF is an upstream initiative aimed at lowering the prices of generic drugs and increasing coverage and price consistency. NVBP is a downstream national initiative prioritised for reducing drug prices to achieve value-based purchasing. Process: By associating the number of manufacturers with price cuts, TPF leaves the choice to manufacturers to decide if they want to enter a specific market. In contrast, the Chinese government determines NVBP list and has the authority to choose manufacturer(s) with the lowest price(s). TPF provides clear price information to potential suppliers with unclear order quantity. The NVBP drug price is determined by tendering, while procurement volume is clear and massive. Outcome: The effectiveness of TPF and NVBP is similar, with both achieving a 53% price cut. Both TPF and NVBP experienced efficiency improvement since their establishment, with 98 and 86 drugs priced per year. By comparing 60 drugs covered by both programmes, the NVBP price is 57% of that of the TPF counterpart on average (1.1 to 301.6%), by purchase power parity. Conclusions The tiered pricing scheme is feasible in regions with a stable and mature pharmaceutical market, typically seen in high-income countries, while tendering is more workable in low- and middle-income countries where the pharmaceutical market is weak and unstable. Experience in the two countries shows that a coordinated pricing mechanism involves many piecemeal interactive problems, which a sophisticated system with a robust long-range plan may address better.

Age group typically identifies millennials – those born between 1982 and 2004. Yet our research challenges the designation based on age group by considering this population in the context of an individual's citizenship or culture. Based on tenets of social identity theory, we explore a citizen's personal value orientation and cognitive moral reasoning to discover commonalities or differences across individuals from eight countries. We report wide variations among citizens' personal value orientations and principled moral reasoning despite being borne within an identified age group. We conclude that an individual's geographic context is a stronger classification descriptor based on values and moral reasoning than their age-based generational categories. Implications for business practice and scholarly research are discussed. [ABSTRACT FROM AUTHOR]

Purpose: This paper aimed to examine moderate-to-vigorous physical activity (MVPA) levels in physical education. Method: A review of reviews was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The screening process, data extraction, assessment of the risk of bias, and analysis of the results were carried out independently by two reviewers. A total of eight systematic reviews from six databases, which included 224 studies, involving more than 80,000 students (elementary, middle, and high school), enrolled in more than 450 schools worldwide were unpacked. Results: Students fail to meet the 50% recommendation of MVPA lesson time, irrespective of country, school stage, gender, or MVPA measures. Physical education-based interventions increased students' MVPA during lessons (range 14.3%-24%) compared with control groups. Conclusion: Physical education is uniquely positioned to provide physical activity opportunities for students, but teachers must target the provision of adequate MVPA levels, which is not currently happening.

In this work, a bibliometric analysis of the investigations of the last 54 years focused on the teaching of topology and its applications in the learning of other areas of knowledge was carried out. The articles that appear in the SCOPUS database were taken into account under the search criteria of the words topology and teaching, connected with the Boolean expression AND in the search field ABS. As a result, 329 articles were obtained which, based on the PRISMA methodology, were reduced to 74 papers. In them publication trends, impact of publications, citation frequencies, among others, were compared. In addition, its use was identified for learning topology at different levels of training, areas of knowledge where this discipline is most applied and strategies used to teach these applications.

This study aimed to assess the impact of the eThekwini Municipality reforestation project on the quality of the soil within the reforestation sites, and water from the nearby rivers (White and Black Mhlasini Rivers) situated at the reforested Buffelsdraai area in KwaZulu-Natal, South Africa. This was the first evaluation of the effect of reforestation on the reduction of selected organic pollutants to be conducted in this area. The sixteen polyaromatic hydrocarbons analysed are on the Environmental Protection Agency (EPA) list of priority pollutants. The soil and sediment samples were extracted using ultrasonication, and liquid-liquid extraction was utilised for the water samples. Gas chromatography mass spectrometry (GCMS) was used to analyze the PAHs. PAH recoveries ranged between 60 and 110%. The PAH LOD values were between 0.30 and 0.69 μg g -1 and LOQ values ranged between 0.99 and 1.9 μg g -1 . The total PAH concentrations determined were between 4.258 and 6.426 μg g -1 in the soil samples, 2.210-13.900 μg g -1 in sediment, and 6.360-85.468 ng L -1 in river water. A comparison between all samples and their respective control, showed that reforestation is potentially reducing the concentration of PAH pollutants. The concentration of pollutants was determined to be lower within the reforestation boundaries and higher outside the reforestation boundary. The total concentration for specific PAHs was above the threshold value for most sampling sites according to Canadian environmental guidelines., 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 © 2022 Elsevier Ltd.

Purpose: Despite its practical importance, the emotion of awe has received scant research attention in the organizational literature. To facilitate future scholarship on this important topic, the authors explore and compare the elicitors of awe at work in three countries representing two culture clusters, including the USA and Canada (the Anglo cluster) and China (the Confucian Asia cluster). Design/methodology/approach: The authors gathered responses from 163 working adults from the USA and Canada and 126 working adults from China using open-response survey, and analyzed each response following the guidance of grounded theory. Findings: Across cultures, there are 10 common elicitors of awe, including virtue of organization, ability and achievement of organization, beauty of workplace, virtue of colleagues, ability and achievement of colleagues, dedication of colleagues, charisma of colleagues, status and power of colleagues, personal growth and achievement and perceived meaningfulness. Looking within cultures, the authors found two awe elicitors that are specific to China: status and power of organization, and work content. Practical implications: Organizations and supervisors wishing to induce the emotion of awe would be well-advised to pay attention to the design of their workplace, as well as their attitudes and behaviors toward employees, customers and the general public. Originality/value: This study contributes to the emotion literature, organizational literature and cross-cultural literature by demonstrating elicitors of awe in the workplace across the Anglo cluster and the Confucian Asia cluster.

Clusters of genetically similar infections suggest rapid transmission and may indicate priorities for public health action or reveal underlying epidemiological processes. However, clusters often require user-defined thresholds and are sensitive to non-epidemiological factors, such as non-random sampling. Consequently the ideal threshold for public health applications varies substantially across settings. Here, we show a method which selects optimal thresholds for phylogenetic (subset tree) clustering based on population. We evaluated this method on HIV-1 pol datasets (n = 14, 221 sequences) from four sites in USA (Tennessee, Washington), Canada (Northern Alberta) and China (Beijing). Clusters were defined by tips descending from an ancestral node (with a minimum bootstrap support of 95%) through a series of branches, each with a length below a given threshold. Next, we used pplacer to graft new cases to the fixed tree by maximum likelihood. We evaluated the effect of varying branch-length thresholds on cluster growth as a count outcome by fitting two Poisson regression models: a null model that predicts growth from cluster size, and an alternative model that includes mean collection date as an additional covariate. The alternative model was favoured by AIC across most thresholds, with optimal (greatest difference in AIC) thresholds ranging 0.007–0.013 across sites. The range of optimal thresholds was more variable when re-sampling 80% of the data by location (IQR 0.008 − 0.016, n = 100 replicates). Our results use prospective phylogenetic cluster growth and suggest that there is more variation in effective thresholds for public health than those typically used in clustering studies. Author summary: A genetic cluster of virus infections is a group of DNA or RNA sequences that are much more similar to each other than they are to other infections from the same population of hosts. These clusters can reveal where virus transmission has been occurring the most rapidly, which can provide useful information for a public health response. Genetic clusters are often built by reconstructing a phylogeny—a tree-based model of how the sequences are related by common ancestors—and locating distinct parts of the tree with short branches. However, there are no objective, general-purpose criteria for deciding which parts of a tree constitute clusters, and there are an unlimited number of ways to partition a tree into clusters. In this study, we develop a computational method to determine the best clustering criteria based on our ability to predict where the next infections will occur. We apply this method to anonymized HIV-1 sequence data sets from Canada, the United States, and China, to characterize the sensitivity of clustering criteria to different risk populations and sampling contexts. Our results indicate that the clustering criteria typically used for phylogenetic studies of HIV-1 are not optimal for public health applications. [ABSTRACT FROM AUTHOR]

In this study, we contribute to the literature in twofold. First, we analyse the nexus between oil price uncertainty shock and real exchange rate behavior from a global perspective using the Global Vector Autoregressive (GVAR) framework. Second, we attempt to examine the individual countries' characteristics in the propagation of global oil price uncertainty to real exchange rate. Using a newly developed measure of oil price uncertainty, our findings confirm a statistically significant exchange rate depreciation effect on 17 of the 32 countries considered with most of them being oil exporting countries although the magnitude of the initial impact is less severe in strong European economies, Canada and China. Our results have important implications for investors and policymakers. [ABSTRACT FROM AUTHOR]

The aim of the present study was to evaluate the measurement invariance of the School Connectedness Scale for Chinese, Canadian, and Tanzanian adolescents, and to explore the inter association between school connectedness and cyberbullying/cybervictimization. Participants included 3872 adolescents from urban settings in China (N= 2053, Mage=16.36 years, SD = 1.14 years; 44.6% boys), Canada (N = 642, Mage = 12.13 years, SD = 0.77 years; 50.1% boys), and Tanzania (N = 1056, Mage=15.87 years, SD = 2.03 years; 52.8% boys). Adolescents selfreported their cybervictimization and cyberbullying experiences, as well as their perceived school connectedness. Multigroup Confirmatory Factor Analysis revealed an approximate measurement invariance of the scale across the three countries. Chinese students showed the lowest levels of school connectedness while Tanzanian students showed the highest. The findings of the multivariate multigroup regression analyses across the three countries revealed similar relationships between school connectedness and cyberbullying/cybervictimization, thus broadening our understanding of school connectedness and its relationship to cyberbullying/cybervictimization across these three different countries.

This study examines how and when passionate leaders can instigate work passion in their followers. We propose relational energy as a social interaction mediator that can facilitate the crossover of work passion from leader to followers. Additionally, we introduce a moderator of culture (Anglo culture, e.g., Canada vs. Confucian Asian culture, e.g., China) as it plays a vital role in the dynamics of interpersonal relations within a leader-follower dyad. We collected two-wave data from MBA students of two Confucian Asian countries (China and Singapore, n = 120) and two Anglo countries (Canada and Australia, n = 265) to test our moderated mediation model. The results show that interactions with passionate leaders can generate relational energy in followers and subsequently lead to followers' passion for work. Furthermore, the findings shed light on the moderating effect of culture, such that the leader-follower work passion relationship via follower relational energy was stronger for followers from Anglo culture than the followers from Confucian Asian culture. Limitations of the study and directions for future research are discussed. [ABSTRACT FROM AUTHOR]

SAGD technology has been successfully and widely applied in the development of superheavy oil and oil sand projects. Before normal SAGD process, some preheating ways are often needed to realize interwell hydraulic connection, and this means that determining reasonable SAGD conversion timing from the preheating stage is an essential precondition for good performance. Previous numerical simulations or qualitative analysis of temperature fall-off data are often adopted in the industry, but they have deficiencies in terms of dependent on static geological model or insufficient data utilization. Therefore, on the basis of the temperature and pressure monitoring process comparison in China's superheavy oil and Canada's oil sand projects, this paper proposed a temperature fall-off interpretation model to obtain thermal diffusivity and preheating radius at different measurement points along the horizontal section by combining an unsteady thermal conduction model under constant heating power of wellbores in the radial coordinate system and approximately unsteady thermal conduction model with constant wellbore temperature and Fourier's law of thermal conduction. Besides, the duration time, interpretation method, and application flow chart of temperature fall-off test were presented. Then, it was validated to successfully determine the timing of SAGD conversion from the preheating stage by an example combining with tracking numerical simulation, temperature inflection point analysis, and index analysis during the partial-SAGD and initial SAGD stages. The findings of this study can help determine the SAGD conversion timing from the preheating stage simpler and faster especially for the case of long horizontal well section deployed with more temperature measurement points.

Studies related to oil and gas wells have attracted worldwide interest due to the increasing energy shortfall and the requirement of sustainable development and environmental protection. However, the state of oil and gas wells in terms of research characteristics, technological megatrends, article-produced patterns, leading study items, hot topics, and frontiers is unclear. This work is aimed at filling the research gaps by performing a comprehensive bibliometric analysis of 6197 articles related to oil and gas wells published between 1900 and 2021. VOSviewer and CiteSpace software were used as the main data analysis and visualization tools. The analysis shows that the annual variation of article numbers, interdisciplinary numbers, and cumulative citations followed exponential growth. Oil and gas well research has promoted the expansion of research fields such as engineering, energy and fuels, geology, environmental sciences and ecology, materials science, and chemistry. The top 10 influential studies mainly focused on shale gas extraction and its impact on the environment. More studies were produced by larger author teams and inter-institution collaborations. Elkatatny and Guo have greatly contributed to the application of artificial intelligence in oil and gas wells. The two most contributing institutions were the Southwest Petr Univ and China Univ Petr from China. The People's Republic of China, the US, and Canada were the countries with the most contributions to the development of oil and gas wells. The authoritative journal in engineering technology was J Petrol Sci Eng, in environment technology was Environ Sci Technol, in geology was Aapg Bull, and in materials was Cement Concrete Res. The keyword co-occurrence network cluster analysis indicated that oil well cement, new energy development, machine learning, hydraulic fracturing, and natural gas and oil wells are the predominant research topics. The research frontiers were oil extraction and its harmful components (1992–2016), oil and gas wells (1997–2016), porous media (2007–2016), and hydrogen and shale gas (2012–2021). This paper comprehensively and quantitatively analyzes all aspects of oil and gas well research for the first time and presents valuable information about active and authoritative research entities, cooperation patterns, technology trends, hotspots, and frontiers. Therefore, it can help governments, policymakers, related companies, and the scientific community understand the global progress in oil and gas well research and provide a reference for technology development and application.

The paper provides a systematic review of satellite-based regional and urban heat island (RHI and UHI) studies in cities and their challenges, from 2010 to the present based on visualizing scientific landscapes (VOS) viewer analysis and Scopus and science database search using a set of standard criteria. The review results show that 52.17% of the studies used Landsat images followed by MODIS (36.65%). Based on VOS viewer analysis author keywords, remote sensing was strongly linked to urban heat island, urban greenspace, and improvise surface, respectively. Regarding, Co-authorship network China, Canada and the United kingdom's authors actively collaborated with different world researchers. The most frequently studied regions and periods of research are China and summer daytime, respectively. A total of 55% of the articles reported the use of a mono-window algorithm for retrieving LST from sensors. On the other hand, remotely sensed UHI studies have been facing a series of challenges, including differences between remote sensing satellite-derived LST and air temperature, impacts of clouds and other factors on LST data, methods to quantify UHI, accuracy assessment and attribution of RHI and UHI. Thus, consideration was given to the understudied cities, the methods to compute RHI and/or UHI intensity, inter-annual variability and modeling in the future. [ABSTRACT FROM AUTHOR]

Objectives To compare demographic and clinical characteristics of patients with axial SpA (axSpA) across geographic regions. Methods Patients With Axial Spondyloarthritis: Multicountry Registry of Clinical Characteristics (PROOF) is an observational study that enrolled recently diagnosed (≤1 year) axSpA patients fulfilling the Assessment of SpondyloArthritis international Society classification criteria from rheumatology clinical practices in 29 countries across six geographic regions. Demographics and disease-related parameters were collected. Here we present baseline data for patients who were classified as radiographic axSpA (r-axSpA) or non-radiographic axSpA (nr-axSpA) confirmed by central reading. Results Of the 2170 patients enrolled, 1553 were classified based on central evaluation of sacroiliac radiographs [r-axSpA: 1023 (66%); nr-axSpA: 530 (34%)]. Patients with nr-axSpA had a significantly higher occurrence of enthesitis (40% vs 33%), psoriasis (10% vs 5%) and IBD (4% vs 2%) vs r-axSpA patients. Significant differences in axSpA characteristics were observed between geographic regions. The highest occurrence of peripheral arthritis (60%), enthesitis (52%) and dactylitis (12%) was in Latin America, and the lowest was in Canada (9%, 9% and 2%, respectively). The occurrence of uveitis and psoriasis was highest in Canada (18% and 14%, respectively) and lowest in China (6% and <1%, respectively). IBD was highest in Arabia (21%), and no cases were observed in China. In multivariable analysis adjusted for factors potentially affecting peripheral and extramusculoskeletal manifestations, geographic regions still exhibited significant differences in frequencies of uveitis (P  < 0.01), psoriasis (P  < 0.0001) and peripheral arthritis (P  < 0.0001). Conclusion The multinational PROOF study of axSpA patients showed significant regional differences in peripheral and extramusculoskeletal manifestations of SpA, which could be considered in management guidelines and clinical trials.

Given the high level of economic and financial globalization, geopolitical tensions can disrupt international trade and negatively influence financial markets. China, a global economic power, has been at the center stage of recent geopolitical tensions with widespread economic implications. We empirically investigate the effect of China's geopolitical risk on Canada's equity markets. The results show a persistent impact on market returns and volatility, most prominently on the resources and energy sectors. Even though China plays a smaller role than the US as a trading partner, China's geopolitical risk significantly affects the Canadian stock market and its component sectors. Our results, therefore, support the need for a constructive approach toward alleviating global geopolitical tensions and for the development of geopolitical risk hedging strategies such as insurance and investment in commodities at the country and investor levels.

Perfluorinated alkyl substances (PFAS) were determined in human milk samples (n = 664) from participants in the Maternal-Infant Research on Environmental Chemicals (MIREC) study. ΣPFAS concentrations (sum of seven PFAS) ranged from 3.1 ng L -1 to 603 ng L -1 , with a median concentration of 106 ng L -1 in the Canadian mothers' milk analyzed. These data comprise the first pan-Canadian dataset of PFAS in human milk. Perfluorooctanoic acid (PFOA) and linear perfluorooctanesulfonate (L-PFOS) were the dominant contributors to ΣPFAS in human milk samples. An inverse relationship between ΣPFAS concentrations and age was observed (Spearman correlation - 0.184). Primiparous women had elevated PFAS concentrations in milk relative to women who had children previously (p < 0.001). In contrast, the region of maternal birth did not influence ΣPFAS concentrations (p = 0.156). Although China and Norway have observed consistently detectable levels of perfluoroundecanoic acid (PFUdA) in human milk, PFAS with long carbon chains (n ≥ 11) were not present above method detection limits in Canadian human milk samples analyzed as part of the MIREC study. In conclusion, despite the presence of low levels of environmental contaminants in human milk, Health Canada supports breastfeeding due to the benefits to both infants and mothers., 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., (Crown Copyright © 2022.

China is the world's largest pesticide user. These chemicals are bioaccumulative in the human body, and eventually could be transferred from the mother to the fetus/infant via placental and breastfeeding transport, which might pose developmental deficiency risks. In this study, human biomonitoring of legacy pesticides was conducted in three Chinese cities using 60 breast milk samples. The patterns, chemical structural signatures, and the estimated daily intake of pesticides were assessed. The median concentration of HCB (57.8 ng g -1 lw, Interquartile range: 28.5-76.9 ng g -1 lw) was the highest among all pesticides, whereas the HCHs, DDXs, TCVP, and heptachlor were also detected. A significantly different pattern of pesticides was found among three sampling cities: the Mianyang cases were mostly DDXs oriented while the Wuhan and Hangzhou cases were under HCB, HCHs, TCVP, and heptachlor influences. Maternal age and pre-pregnancy BMI were found to be the influencing factors for the pesticides in the breast milk, and dietary preferences were an important factor in the exposure scenario. Chemical structural signatures indicated that for HCHs and DDXs the exposure was mostly historical, while the lindane and dicofol exposure may exist among the volunteering mothers. The EF for chiral pesticides did not deviate significantly from the racemic value. The risk from breastfeeding was negligible according to the Chinese and UN standard, while some cases from Hangzhou and Wuhan exceeded the Canadian restrictions. Thus, the adverse health effects of chemical exposure by dietary intake for infants need to be closely monitored in future studies., 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 © 2022 Elsevier B.V.

Based on the latest coronavirus corpus of the English corpus collection list (English-corpora), this paper aims to do the data mining of the China-related reports reported by the media of the United States, Canada, Britain, and Australia in public health emergencies. It tries to analyze how the English world media construct China's national image on the basis of the theory of evidentiality. It is found that the national media in the English world media report on China's national image show a dynamic process of "concern-worry-stigmatization-dumping." The western media made the construction of China's national image by subjective reports, objective but negative media discourse, and "double standards.", Competing Interests: The author declares that there are no conflicts of interest regarding the present study., (Copyright © 2022 Dian Zhang.)
