This paper examines two distinct corporate theories, shareholder primacy and entity theory, as foundations of corporate governance and their implications for corporate sustainability. Specifically, the purpose of this paper is to argue for a shift in perspective away from shareholder primacy towards an alternative approach—entity theory. It considers why shareholder primacy as a foundation for governance is problematic for facilitating sustainable business decisions and suggests that conceptualizing the company as an entity would provide a more appropriate theoretical foundation for governance which lends itself to sustainable corporate conduct. Although abstract in isolation, such corporate theories can have real world influence on governance and subsequently director behavior. This point is illustrated by contrasting the extent to which directors, as part of their duty to act in good faith in the best interests of the company, can factor sustainability interests into their business decisions across a shareholder orientated jurisdiction, the United Kingdom, and an entity orientated jurisdiction, Canada. The analysis demonstrates the implications of entity theory for sustainable director decisions when acting in the best interests of the company; namely, a reduction of the pressures associated with the shareholder primacy drive, broader notions of what constitutes corporate interest, and a recognition of the entity's role in society to behave as a good corporate citizen.

Background: Chest low-dose computed tomography (LDCT) is a promising technology for population-based screening because it is non-invasive, relatively inexpensive, associated with low radiation and highly sensitive to lung cancer. To improve the cost-effectiveness of lung cancer screening, simultaneous screening for other diseases could be considered. This systematic review was conducted to analyse studies that published evidence on the cost-effectiveness of chest LDCT screening programs for different diseases. Methods: Scopus and PubMed were searched for English publications (1 January 2011–22 July 2022) using search terms related to screening, computed tomography and cost-effectiveness. An additional search specifically searched for the cost-effectiveness of screening for lung cancer, chronic obstructive pulmonary disease or cardiovascular disease. Included publications should present a full health economic evaluation of population screening with chest LDCT. The extracted data included the disease screened for, model type, country context of screening, inclusion of comorbidities or incidental findings, incremental costs, incremental effects and the resulting cost-effectiveness ratio amongst others. Reporting quality was assessed using the 2022 Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. Results: The search yielded 1799 unique papers, of which 43 were included. Most papers focused on lung cancer screening (n = 40), and three were on coronary calcium scoring. Microsimulation was the most commonly applied modelling type (n = 16), followed by life table analysis (n = 10) and Markov cohort models (n = 10). Studies reflected the healthcare context of the US (n = 15), Canada (n = 4), the UK (n = 3) and 13 other countries. The reported incremental cost-effectiveness ratio ranged from US$10,000 to US$90,000/quality-adjusted life year (QALY) for lung cancer screening compared to no screening and was US$15,900/QALY–US$45,300/QALY for coronary calcium scoring compared to no screening. Discussion: Almost all health economic evaluations of LDCT screening focused on lung cancer. Literature regarding the health economic benefits of simultaneous LDCT screening for multiple diseases is absent. Most studies suggest LDCT screening is cost-effective for current and former smokers aged 55–74 with a minimum of 30 pack-years of smoking history. Consequently, more evidence on LDCT is needed to support further cost-effectiveness analyses. Preferably evidence on simultaneous screening for multiple diseases is needed, but alternatively, on single-disease screening.

Almost 80 million people globally are forcibly displaced. A small number reach wealthy western countries and seek asylum. Over half are children. Wealthy reception countries have increasingly adopted restrictive reception practices including immigration detention. There is an expanding literature on the mental health impacts of immigration detention for adults, but less about children. This scoping review identified 22 studies of children detained by 6 countries (Australia, Canada, Hong Kong, Netherlands, the UK and the US) through searches of Medline, PsychINFO, Emcare, CINAHL and Scopus data bases for the period January 1992–May 2019. The results are presented thematically. There is quantitative data about the mental health of children and parents who are detained and qualitative evidence includes the words and drawings of detained children. The papers are predominantly small cross-sectional studies using mixed methodologies with convenience samples. Despite weaknesses in individual studies the review provides a rich and consistent picture of the experience and impact of immigration detention on children's wellbeing, parental mental health and parenting. Displaced children are exposed to peri-migration trauma and loss compounded by further adversity while held detained. There are high rates of distress, mental disorder, physical health and developmental problems in children aged from infancy to adolescence which persist after resettlement. Restrictive detention is a particularly adverse reception experience and children and parents should not be detained or separated for immigration purposes. The findings have implications for policy and practice. Clinicians and researchers have a role in advocacy for reception polices that support the wellbeing of accompanied and unaccompanied children who seek asylum. [ABSTRACT FROM AUTHOR]

The second quantum revolution has been producing groundbreaking scientific and technological outputs since the early 2000s; however, the scientific literature on the impact of this revolution on the industry, specifically on start-ups, is limited. In this paper, we present a landscaping study with a gathered dataset of 441 companies from 42 countries that we identify as quantum start-ups, meaning that they mainly focus on quantum technologies (QT) as their primary priority business. We answer the following questions: (1) What are the temporal and geographical distributions of the quantum start-ups? (2) How can we categorize them, and how are these categories populated? (3) Are there any patterns that we can derive from empirical data on trends? We found that more than 92% of these companies have been founded within the last 10 years, and more than 50% of them are located in the US, the UK, and Canada. We categorized the QT start-ups into six fields: (i) complementary technologies, (ii) quantum computing (hardware), (iii) quantum computing (software/application/simulation), (iv) quantum cryptography/communication, (v) quantum sensing and metrology, and (vi) supporting companies, and analyzed the population of each field both for countries, and temporally. Finally, we argue that low levels of quantum start-up activity in a country might be an indicator of a national initiative to be adopted afterwards, which later sees both an increase in the number of start-ups, and a diversification of activity in different QT fields.

This paper provides a narrative review of the existing literature on differences in demographic and biological features of breast cancer at time of diagnosis between Black and White women in Canada, the United Kingdom and the United States. Electronic database searches for published peer-reviewed articles on this topic were conducted, and 78 articles were included in the final narrative review. Differences between Black and White women were compared for eight categories including age, tumour stage, size, grade, lymph node involvement, and hormone status. Black women were significantly more likely to present with less favourable tumour features at the time of diagnosis than White women. Significant differences were reported in age at diagnosis, tumour stage, size, grade and hormone status, particularly triple negative breast cancer. Limitations on the generalizability of the review findings are discussed, as well as the implications of these findings on future research, especially within the Canadian context.

Objective: To assess rates of traversing barriers to care to access optimal clinical outcomes in people with migraine internationally. Background: People in need of medical care for migraine should consult a health care professional knowledgeable in migraine management, obtain an accurate diagnosis, and receive an individualized treatment plan, which includes scientific society guideline-recommended treatments where appropriate. Methods: The Chronic Migraine Epidemiology and Outcomes-International (CaMEO-I) Study was a cross-sectional, web-based survey conducted from July 2021 through March 2022 in Canada, France, Germany, Japan, the United Kingdom, and the United States (US). Respondents who met modified International Classification of Headache Disorders, 3rd edition, criteria for migraine and had Migraine Disability Assessment Scale (MIDAS) scores of ≥ 6 (i.e., mild, moderate, or severe disability) were deemed to need medical care and were included in this analysis. Minimally effective treatment required that participants were currently consulting a health care professional for headache (barrier 1), reported an accurate diagnosis (barrier 2), and reported use of minimally appropriate pharmacologic treatment (barrier 3; based on American Headache Society 2021 Consensus Statement recommendations). Proportions of respondents who successfully traversed each barrier were calculated, and chi-square tests were used to assess overall difference among countries. Results: Among 14,492 respondents with migraine, 8,330 had MIDAS scores of ≥ 6, were deemed in need of medical care, and were included in this analysis. Current headache consultation was reported by 35.1% (2926/8330) of respondents. Compared with the US, consultation rates and diagnosis rates were statistically significantly lower in all other countries except France where they were statistically significantly higher. Total appropriate treatment rates were also statistically significantly lower in all other countries compared with the US except France, which did not differ from the US. All 3 barriers were traversed by only 11.5% (955/8330) of respondents, with differences among countries (P < 0.001). Conclusions: Of people with migraine in need of medical care for migraine, less than 15% traverse all 3 barriers to care. Although rates of consultation, diagnosis, and treatment differed among countries, improvements are needed in all countries studied to reduce the global burden of migraine. Trial registration: NA.

Epidemiological evidence suggests that regular physical activity (PA) positively impacts individuals' mental health (MH). The PA-MH relationship may be critical among immigrants owing to psycho-social-cultural influences. This scoping review of 61 studies employed a holistic bio-psycho-socio-cultural framework to thoroughly investigate the complex relationship between PA (across life domains) and immigrants' MH in Western countries. A systematic search of five electronic databases (Medline, PubMed, Embase, PsycINFO and Anthropology Plus) was conducted to locate relevant articles. No limitations were applied to study design, age, gender, home country, MH condition or PA type. A bio-psycho-socio-cultural-informed conceptual model guided the analysis of the multi-domain PA-MH relationship. Immigrant PA-MH studies were conducted and reported most commonly in the USA (38%), Australia (18%), and Canada (11%). Overall, PA was positively related to MH. Each domain-specific PA appeared to be associated with unique MH-promoting pathways/mechanisms. Leisure-related PA may support MH by enhancing self-agency and minimizing risky behaviors, whilst travel- and domestic-related PA may promote self-accomplishment and physical engagement. Ethnic sports appeared to enhance resilience. Occupational-related PA was associated with either positive or negative MH, depending on the type of occupation. A bio-psycho-socio-cultural-informed model is required to gain an encompassing and integrated understanding of immigrants' health. The first iteration of such a model is presented here, along with an illustration of how the model may be used to deepen analysis and understanding of the multi-domain PA-MH relationship among immigrants and inform public health planners and practitioners.

Millions of people cross political borders yearly without having the proper documents. This has led to increased detention and deportation practices in destination countries for reasons related to security and sovereignty. The objective of the current study was to analyze and visualize research publications on the detention and deportation of migrants to identify current research hotspots, research gaps, and potential future research in the field. Relevant research articles were obtained from the Scopus database for the study period from 1900 to December 31, 2022. The analysis included presentations of key contributors to the field and visualization of topics, themes, and international collaboration. In total, 906 articles were found. The earliest was in 1982. The majority of articles were published in journals within the subject areas of social sciences and humanities. The number of publications showed a steep rise from 2011 to 2022. The Journal of Ethnic and Migration Studies was the most prolific, but publications in the Citizenship Studies journal received the highest number of citations per article. Researchers from the United States contributed the most. Mexico ranked fifth in the number of publications. Oxford University was the most prolific institution, followed by three universities in Australia. The majority of articles were single-authored, indicative of limited author-author collaboration. Research hotspots in the field were "human rights" and "mental health". The detention and deportation of Mexican and other Latino migrants in the United States constituted a distinct research theme in the field. International research collaboration was limited by geographical proximity (e.g., the United States and Mexico) or common language (e.g., the United Kingdom and Australia). Future research topics should focus on alternatives to detention, family separation, and healthcare services for detained migrants. Research activity on detention and deportation is required from all world regions, including the source countries of migrants. Future research should promote alternatives to traditional detentions. The contribution of countries in Africa, the Middle East, and South-Eastern Asian regions needs to be encouraged. Future research on the detention and deportation of non-Latino migrants is highly required. [ABSTRACT FROM AUTHOR]

This study assesses the role of government spending on environmental sustainability based on a framework that combines the environmental Kuznets curve (EKC) hypothesis with the Armey curve hypothesis. Specifically, the inverted U-shaped relationships between carbon (CO2) emissions and economic growth (EKC hypothesis) and between government spending and economic growth (Armey curve hypothesis) are analyzed using a composite EKC model tested for cross-sectional dependence and heterogeneity, panel unit root, panel co-integration, and the augmented mean group estimation. In so doing, this study pursues a potential transmission mechanism leading from government spending to CO2 emissions through the growth channel and presents a novel way to develop a better understanding of how economic growth policy and energy policy can be synchronized. Empirical results show that economic growth acts as a transmitter between government spending and CO2 emissions in the USA, UK, and Canada. However, the composite EKC hypotehesis is confirmed only for the USA and Canada, where the optimal level of government spending that maximizes CO2 emissions is 29.87% and 29.22% of GDP, respectively. In contrast, the optimal level of government spending equivalent to 28.30% of GDP minimizes CO2 emissions in the UK. The key policy implication is that governments can achieve sustainable economic growth by setting standards for their spending levels. [ABSTRACT FROM AUTHOR]

Applying a mixed frequency vector autoregressive (MF-VAR) approach, we examine relationships between CO2 emissions and economic growth from 1970Q1 to 2019Q4 among G7 countries. We incorporate primary energy consumption as a control variable, to avoid any bias from an omitted variable. Our empirical results, using forecast error variance decomposition and a Granger causality check, suggest that MF-VAR exhibits better explanatory ability over the more commonly used VAR model employing single frequency data. Results from LF-VAR exhibit a feedback loop connecting economic expansion and emissions of CO2 with one-way Granger causality from primary energy consumption to growth of the economies studied. MF-VAR model results also indicate that, in G7 countries, economic expansion exhibits a one-way causal link to CO2 emissions in Canada, UK, and US cases. Interestingly, MF-VAR shows feedback between economic expansion and primary energy use in Germany, while LF-VAR quantifies the link from economic growth to CO2 emissions in Canada and from CO2 to economic growth in the UK. Results raise implications for the G7 samples' policymakers. [ABSTRACT FROM AUTHOR]
