"Go to temples of science and ideas of Europe. Imitate the Tugendbund, 'the Union of Virtue', of which thousands of German youth are the members. Always keep the rule of 'Fit soul is in fit body' in mind" (Petrov, 2013, p. 72). This study aimed to show the similarities, in terms of expression, emphasis, and implication, in the about/mission/vision/goals/objectives of various science centers from around the world and in the basic themes derived from Snellman's statement above, namely, Science for all, Science Centers for all, and Human welfare that he made as a challenge to not only his people but to everyone. Document and content analyses were applied in the study. Within the scope of these analyses, this study investigated the about/mission/vision/goals/objectives sections of websites of science centers from around the world (Asia, Europe, Global, Latin America/The Caribbean, North America, Africa). From this investigation, similar basic themes, derived from Snellman's statement challenging his people/everyone to adopt this devotion to science, were found in the areas of i) expression in ASTC, CIMUSET/CSTM, CASC and SAASTEC; ii) emphasis in ECSITE, ASDC, ASCN and NSCF; and iii) implication in ASPAC, ASTEN, NCSM, ABCMC and Red-POP. These basic themes, as found in the about/mission/vision/goals/objectives of science centers, can, in effect, be narrowed down to the one theme of "cultural institutions will be a big part of human life" (Madsen 2017, p. 68) science centers in the global village (Touraine, 2016, p. 121) of the future.

Background: Early puberty is a common worldwide problem. Different parameters as genetics, metabolic diseases, obesity, as well as environmental factors may affect the age of puberty. This systematic review aims to survey the related literature on the effects of environmental pollutants and especially organohalogens and phthalates on early puberty. Materials and Methods: A systematic review of papers published in the English language was completed in January 2014. Studies on the associations of organohalogens and phthalates with the puberty time were included. A literature search was conducted in EMBASE, PubMed, Scopus, ISI Web of Science, and Cochrane Library from 1995 to January 2014; moreover manual search through references of relevant manuscripts was considered. The literature search identified 212 papers, of which 13 papers fulfilled the inclusion criteria of the current study. Two reviewers independently identified relevant papers for potential inclusion and assessed the methodological quality. Results: This review included 6572 participants in nine countries from three continents (Europe, North America, and Asia). Different studies determined the effects of pollutants on maturation signs and pubertal stages and confirmed the association of organohalogens and phthalates with early puberty. Conclusion: Based on the studied literature, environmental pollutants surround and accumulate in human societies and their adverse health effects are well documented. It can be concluded that organohalogens and phthalates are disturbing the normal process of puberty timing; especially their influence on early maturation in girls should be underscored.

Background: Syndromic surveillance provides public health intelligence to aid in early warning and monitoring of public health impacts (e.g. seasonal influenza), or reassurance when an impact has not occurred. Using information collected during routine patient care, syndromic surveillance can be based on signs/symptoms/preliminary diagnoses. This approach makes syndromic surveillance much timelier than surveillance requiring laboratory confirmed diagnoses. The provision of healthcare services and patient access to them varies globally. However, emergency departments (EDs) exist worldwide, providing unscheduled urgent care to people in acute need. This provision of care makes ED syndromic surveillance (EDSyS) a potentially valuable tool for public health surveillance internationally. The objective of this study was to identify and describe the key characteristics of EDSyS systems that have been established and used globally.Methods: We systematically reviewed studies published in peer review journals and presented at International Society of Infectious Disease Surveillance conferences (up to and including 2017) to identify EDSyS systems which have been created and used for public health purposes. Search criteria developed to identify "emergency department" and "syndromic surveillance" were applied to NICE healthcare, Global Health and Scopus databases.Results: In total, 559 studies were identified as eligible for inclusion in the review, comprising 136 journal articles and 423 conference abstracts/papers. From these studies we identified 115 EDSyS systems in 15 different countries/territories across North America, Europe, Asia and Australasia. Systems ranged from local surveillance based on a single ED, to comprehensive national systems. National EDSyS systems were identified in 8 countries/territories: 2 reported inclusion of ≥85% of ED visits nationally (France and Taiwan).Conclusions: EDSyS provides a valuable tool for the identification and monitoring of trends in severe illness. Technological advances, particularly in the emergency care patient record, have enabled the evolution of EDSyS over time. EDSyS reporting has become closer to 'real-time', with automated, secure electronic extraction and analysis possible on a daily, or more frequent basis. The dissemination of methods employed and evidence of successful application to public health practice should be encouraged to support learning from best practice, enabling future improvement, harmonisation and collaboration between systems in future.Prospero Number: CRD42017069150 .

The aim of this study is to investigate the effects of countries' development level in sports medicine, exercise and sports performance on their success in Olympic Games. Within this purpose, 1027 papers that were published between 2010 and 2018 in the journal of Sports Medicine, of which impact factor was 7.074 in 2017, were examined in analytical and correlational terms considering the first author and total author numbers. Pearson Correlation was utilized to find out the relationships between the papers from various countries and their success at Olympic Games. Regarding the number of medals won by the countries in the 2016, 2012 and 2008, Olympic Games were found significantly correlated with the number of first author (r = 0.73) and total author (r = 0.74).

Emergence and development of the blockchain technology, which is able to transform into "a most powerful disruptive innovation", shall definitely concern universities. Moreover, nowadays the blockchain technology meets the challenges that both the system of higher education and the entire society are currently facing. Advantages of the blockchain technology are decentralized open data, absence of forgeries, safe storage of information, and reduction of transaction expenses related to data checkup, control, and verification. This paper provides a critical analysis of application of the blockchain technology considering with its applicability opportunities and restrictions in education; it also aims to identify the consequences of its influence upon the development of education. The article analyzes real cases when this technology was applied, with the Massachusetts Institute of Technology (MIT) as an example. The MIT applied it to protect and validate the certificates that it issued. Another example is the Sony Global Education that forms individual data on its trainees' competencies and productivity; a third one relates to the University of Nicosia, which was the first to use smart contracts and accept cryptocurrency as a form of payment. The paper also considers the elements of the blockchain technology at universities (both in Russia and outside it), which participate in massive open online courses. It determines the scope of application of this technology in the Russian educational system. In addition, this article provides a literature review related to application of the blockchain technology; the review includes works by such renowned researchers as D. Tapscott, B. Bleir, A. Watters, A. Grech, A. Camilleri, M. Swan, A. Zaslavsky, etc. The paper analyzes the obtained findings of the survey that its authors have conducted among experts, professors, and specialists involved in accreditation. Thus, the paper provides an analysis of opportunities and restrictions related to application of the blockchain technology in higher education.

The increase in liquefied natural gas trade has accelerated the integration of previously segmented markets in North America, Europe, and Asia. This paper provides evidence on the integration of the transatlantic natural gas market; it thus complements other papers in the EMF 23 study that focus on prices and international natural gas trade. We test the theoretical proposition that in integrating markets commodity prices should move closer than before. Using 2,059 pairs of daily spot prices for natural gas in North America and Europe we investigate price dynamics covering the period from 1999 until 2008. We apply the Kalman Filter technique which measures convergence by allowing for dynamic structural change to gain detailed information on trends inherent in prices over time. Results suggest an increasing convergence of spot prices on either side of the Atlantic Basin. [ABSTRACT FROM AUTHOR]

Vitamin D deficiency (25-hydroxyvitamin D; 25(OH)D) is at epidemic proportions in western dwelling South Asian populations, including severe deficiency (<12⋅5 nmol/l) in 27-60% of individuals, depending on season. The paper aimed to review the literature concerning vitamin D concentrations in this population group. Research from the UK and Europe suggests a high prevalence of South Asians with 25(OH)D concentration <25 nmol/l, with most having a 25(OH)D concentration of <50 nmol/l. In Canada, South Asians appear to have a slightly higher 25(OH)D concentration. There are few studies from the United States, South Africa and Australasia. Reasons for vitamin D deficiency include low vitamin D intake, relatively high adiposity, sun exposure avoidance and wearing of a covered dress style for cultural reasons. Possible health effects of deficiency include bone diseases such as rickets and hypocalcaemia in children and osteomalacia in adults. Vitamin D deficiency may also increase the risk of other chronic diseases. Increased fortification of food items relevant to South Asian groups (e.g. chapatti flour), as well as increased use of vitamin D supplements may help reduce this epidemic. Introducing culturally acceptable ways of increasing skin exposure to the sun in South Asian women may also be beneficial but further research is needed to assess the effectiveness of different approaches. There may be a need for a South Asian specific vitamin D dietary intake guideline in western countries. To conclude, vitamin D deficiency is epidemic in South Asians living in western countries and there is a clear need for urgent public health action. [ABSTRACT FROM AUTHOR]

Background & Aims: Diabetes and related metabolic syndromes represent a significant global health challenge, with the global burden of diabetes increasing considerably since 1990. In this article, we examined the trend of publications in Endocrinology, Diabetes and Metabolism between 1996 and 2021, focusing on Asian countries. Methods: We obtained and used the data from the Scopus database from the SCImago website (https://www.scimagojr.com/), on 1 April 2023, related to the subspecialty of Endocrinology, Diabetes and Metabolism for country rankings between 1996 and 2021. We did not include any data related to other medical specialties or other fields. Results: There has been a steady rise in global publications on these subspecialties over the past decade, with the number of publications from Asian countries increasing significantly. Western Europe recorded the highest number of publications, followed by North America and Asia. The COVID-19 pandemic also contributed to a surge in publications in this field. In Asian countries, China and India have notably increased their global contribution to publications, with China emerging as the top Asian nation in 2021. Conclusion: Our findings provide valuable insights into the research output from various countries and the productivity trends in Diabetes, Endocrinology and Metabolism-related research.

Simple Summary: We aimed to evaluate the extent to which clinical trials represent countries with different socio-demographic indexes and the availability of tyrosine kinase inhibitors for chronic myeloid leukemia. We found a significant lack of availability for tyrosine kinase inhibitors on the global level, and a lack of equitable distribution of trials across countries is an issue that needs to be addressed. Background: Evaluating clinical trial representation for countries with different socio-demographic index (SDI) and tyrosine kinase inhibitor (TKI) availability for chronic myeloid leukemia (CML). Methods: CML incidence rates (IRs) and disability-adjusted life years (DALYs) (1999–2019) from the Institute of Health Metrics and Evaluation were analyzed. Trials investigating TKI use in CML were obtained from ClinicalTrials.gov. Site data for eligible trials (N = 30) and DALYs were analyzed. TKI approvals, DALYs, and IRs were summarized by SDI. Results: North America (NA) had significant decreases in annual percent change (APC) in DALYs and incidence rates from 1999 to 2004. IRs were highest in Europe and Central Asia (ECA) and NA, while DALYs were highest in South Asia (SAsia) and Sub-Saharan Africa (SSA). Countries in the high-SDI quintile were likely to have lower DALYs than lower-SDI quintiles. Differences in regional DALYs vs. sites in TKI trials were significant for SAsia, SSA, and ECA. High-SDI countries were included in all 30 trials, and TKI approvals were prominent in high-SDI (142) vs. low-SDI (14) countries. Conclusions: The inclusion of disproportionately affected countries during the design of and recruitment into clinical trials should occur, as should TKI availability. The lack of representation demonstrates healthcare disparities. [ABSTRACT FROM AUTHOR]

Background: Accomplishments in stem cell science and tissue engineering have resulted in a remarkable revolution in the context of future medicine. However, a general insight over the progress of stem cell research in Iran is still lacking. A better understanding of current needs in this field is required to design a better national roadmap. Methods: In this study, we defined the geographical regions based on the significance of their contribution to stem cell research; then, using the Scopus database, we retrieved reports from Iran and other countries concerning stem cell science and regenerative medicine published from 1994 until the end of 2016. Results: A significant number of citations belong to North America (6 554 029 citations equal to 49% of the total citations) and Europe (4 425 465 citations equal to 33% of the total citations) and the rest of citations were related to Asia (2 423 352 citations equal to 18% of the total citations). East Asian (2 168 472 citations equal to 76% of the total citations related to Asia) documents were cited more than those from the Middle East (ME) (494 141 citations equal to 17% of the total citations related to Asia) and North and Central Asia (196 382 citations equal to 7% of the total citations related to Asia). Iran as a country in the ME attracted 17% of the total citations related to the Asian countries winning the second position in this regard. The overview of total number of citations showed a sharp increase and upward trend in citation numbers for all the Iranian institutes from 2007 that resulted in the expansion of stem cell science in all major cities of Iran such as Shiraz (8%), Mashhad (5%), Isfahan (5%) and Ahvaz (5%). H-index of Tehran University of Medical Science, which has the highest total citations and document numbers, is the highest among all Iranian research institutes. Citation per paper of Royan Institute (RI) is the highest among the top 10 Iranian institutes, by 13 citations per paper. Conclusion: Stem cell research in Iran is rapidly developing. Since 2007, the number of published documents in major research institutes increased; thus, there is necessity for analysis of the status of publications in this field and choosing a better direction based on needs. Furthermore, it is necessary to expand and organize international collaborations to enrich our research and benefit from different team experiences. [ABSTRACT FROM AUTHOR]

This paper provides global evidence supporting the hypothesis that expected return models are enhanced by the inclusion of variables that describe the evolution of book-to-market--changes in book value, changes in price, and net share issues. This conclusion is supported using data representing North America, Europe, Japan, and Asia. Results are highly consistent across all global regions and hold for small and big market capitalization subsets as well as in different subperiods. Variables measured over the past twelve months are more relevant than variables measured over the past thirty-six months, demonstrating that recent news is more important than old news.

The importance of inclusive education receives global acceptance. The current paper presents a bibliometric analysis of 8398 papers dealing with inclusive education between 1980 and 2019. The research aim is to gain information on scientific productivity, international collaboration activities, and the conceptual structure of this research field. Descriptive analyses, co-authorship collaboration analysis and co-word analysis were conducted to obtain a comprehensive knowledge map of inclusive education research. The results show a fast growing body of research in inclusive education over the years with intensive international collaboration patterns. Six research clusters could be identified. Major and intensively studied research themes are disability issues, teacher professionalisation, teacher practices, attitudes towards inclusive education, social processes, support, curricular issues, student perspective, parent perspective, intercultural education, policy, etc. Research addressing inclusive education from a queer perspective, bullying, stigmatisation, digital education and emerging technologies in inclusive settings are under-represented and should be intensified in future studies.

Simple Summary: The prognosis of children with relapsed/refractory (R/R) acute myeloid leukemia (AML) remains poor, and innovative treatments are needed. Most drugs approved for adults with AML over the last decade are not available or not licensed for use in children. Clinical trials in pediatric AML to assess the safety and/or efficacy of new drugs may take a long time to recruit given smaller patient numbers. The overarching aim of the Pediatric Acute Leukemia (PedAL) program, supported by the Leukemia and Lymphoma Society as part of its Dare to Dream Project, is to establish new standards of care for children with R/R AML via international collaboration in Europe, North America, and Asia-Pacific to accelerate clinical trial conduction, increase access to promising new therapies, and create a registry of uniformly-collected data. These efforts will facilitate biomarker-driven approaches of targeted therapies, of which an overview is provided in this manuscript, with the intent to obtain regulatory approvals. The prognosis of children with acute myeloid leukemia (AML) has improved incrementally over the last few decades. However, at relapse, overall survival (OS) is approximately 40–50% and is even lower for patients with chemo-refractory disease. Effective and less toxic therapies are urgently needed for these children. The Pediatric Acute Leukemia (PedAL) program is a strategic global initiative that aims to overcome the obstacles in treating children with relapsed/refractory acute leukemia and is supported by the Leukemia and Lymphoma Society in collaboration with the Children's Oncology Group, the Innovative Therapies for Children with Cancer consortium, and the European Pediatric Acute Leukemia (EuPAL) foundation, amongst others. In Europe, the study is set up as a complex clinical trial with a stratification approach to allocate patients to sub-trials of targeted inhibitors at relapse and employing harmonized response and safety definitions across sub-trials. The PedAL/EuPAL international collaboration aims to determine new standards of care for AML in a first and second relapse, using biology-based selection markers for treatment stratification, and deliver essential data to move drugs to front-line pediatric AML studies. An overview of potential treatment targets in pediatric AML, focused on drugs that are planned to be included in the PedAL/EuPAL project, is provided in this manuscript. [ABSTRACT FROM AUTHOR]

Qualitative content analysis is used in this study to review related online education since the outbreak of COVID-19. The aim of this study was to summarize the impact of online teaching on the education industry during the pandemic, sum up the viewpoints of all kinds of people to draw conclusions, and conclude the practical countermeasures. Based on the result of the analysis, firstly, we think that students and teachers are satisfied with online education, but parents have expressed dissatisfaction with this kind of education. Secondly, this paper lists the advantages and common problems of online teaching during study at home from different aspects. According to deficits, we summarize the solutions from three aspects: network equipment, teaching, and self-adjustment. This research is of great significance. It is not only beneficial to the development of educational platforms and personalized teaching but also helps formulate education policy to reduce the burden of education.

Results of international achievement surveys such as the Programme in International Student Assessment have consistently reported an achievement gap between immigrant and non-immigrant student populations around the world. This paper unpacks this persistent achievement gap by examining key characteristics that influence the performance of first- and second-generation immigrant students as well as the policies and practices that are associated with enhanced educational outcomes. A multi-layered framework is proposed to help policymakers juxtapose key characteristics of their immigrant students' achievement against individual, family, school, community, and host society characteristics and policies. The discussion also underscores the importance of connecting this multi-layered framework with other important sectors within governments such as those responsible for the economy, health, social protection, and immigration. This paper also examines limitations with current large-scale data sets and the implications for research and policy analysis.

The article discusses the results of a poll made by the journal "Nature" on what and how metrics are used in academic institutions. It says that 150 readers responded to the survey and provosts, department heads, and other administrators were also surveyed at nearly 30 research institutions throughout the world. It states that three-quarters of the researchers surveyed said that metrics are used in promotion and hiring decisions, and about 70% mentioned that metrics are applied in performance review and tenure decisions. Moreover, most administrators asserted that they ignore the metrics in promotion, hiring, and tenure decisions. It discusses how metrics are used in North America, Europe, and Asia.

This article presents information on the book "Global Competitive Strategies in the new World Economy: Multilateralism, Regionalization and the Transnational Firm," edited by Hafiz Mirza. In this book nineteen papers seek to understand the strategies of transnational firms in an evolving international environment, where issues of globalization, regionalism, and muitilateralism have become salient. Papers also examines the complex relationship between conflict and cooperation that characterizes firms, nation states and supranational groupings, Samsung Group's views on global regionalization strategies, the strategies of transnational corporations in Europe, North America and Asia.

The aim of this study was to compare bibliometric indicators of scientific productivity in physical activity (PA) in children and adolescents with Autism spectrum disorder (ASD) and Down syndrome (DS) in the PubMed database. A bibliometric study was conducted for the last 5 years (2017 to 2021). The data collected for each article were: year of publication, language of publication, country, journal name, and type of paper. The results showed that there was higher scientific productivity in the population with DS (20 studies) relative to their counterparts with ASD (31 studies). The language of publication in both cases was English. There were 10 countries that published on PA in ASD and 14 countries that published on DS. Overall, the greatest interest in publishing on PA in children and adolescents with ASD was in North America (6 studies), followed by Asia (5 studies) and Europe (4 studies). In the DS population it was in Europe (13 studies), North America (9 studies) and South America (4 studies). Nineteen journals were identified that published in the ASD population and 29 journals in DS. Six experimental studies were identified in ASD and 7 in DS. There was a higher scientific productivity with original studies. There was a positive trend of increasing scientific productivity over the years in both populations. We suggest the need to promote research on PA in both populations, regardless of the type of study, as it is an indicator of overall health status.

OVERVIEW: In today's competitive environment, the ability of an organization to innovate is paramount. While most organizations have flashes or spurts of innovation, only a handful have been able to innovate on a continuous and sustained basis. This paper surveys the challenges faced by firms when trying to build sustainable innovation programs. These findings have been derived from an examination of innovation programs in over 30 organizations in North America, Europe and Asia. [ABSTRACT FROM AUTHOR]

This paper evaluates the impact of protected areas on land-cover clearing, using a metadata analysis of information on 49 locations from 22 countries. Protected areas had significantly lower rates of clearing in comparison to their surroundings. In addition, protected areas had also significantly lowered rates of clearing within their boundary following initiation of protection. Thus, protected areas do appear to be effective at limiting overall land-cover clearing. There was some variation in the rates of clearing across regions, where most protected areas from North America and Europe showed positive rates of land-cover change, while protected areas from Asia had the highest rates of land-cover clearing. While most protected areas from North America and Europe involved a relatively smaller number of actors, a greater number of actors and drivers of clearing was implicated in protected areas from Asia, Africa, and Latin America, indicating the increased difficulties faced by park management in these regions. In contrast, country income levels and the International Union for the Conservation of Nature and Natural Resources category of protection did not appear to impact the likelihood of land-cover clearing in protected areas.

Students' action competence must be taught and developed, particularly for prospective science teachers, to have a pedagogical perspective as environmental educators. As indicated by publications in respected journals, researchers' focus and alignment on the issue of action competence are highly expected. This systematic literature review aims to compare the findings of research articles published by Web of Science-indexed journals. The keyword used to find the articles on the Web of Science's database was "action competence," which discovered 193 publications. Furthermore, 25 articles met the criteria to be analyzed. Preferred reporting items for systematic reviews and meta-analysis was the inclusion and exclusion model used. In the last three years, research focused on action competence has increased. The research employed several methods, i.e., qualitative, quantitative, mixed-methods, and development research. Jelle Boevede Pauw and Wanda Sass were the authors who frequently published research that focused on action competence. The keyword action competence was directly associated with environmental education, sustainable development, education-based learning for sustainable development, and evaluation. The authors who published their research with this focus were from 16 countries, mainly from Europe, i.e., Sweden, Belgium, and Denmark. The continent diversity of authors who contributed articles indicated that the action competence issue had become a global concern. Furthermore, it was found that the number of non-collaborating publications (universities or countries) was higher than those collaborating, even though single authors rarely wrote the articles. The recent trend shows that publications are authored by scientists with various backgrounds such as fields, universities, and even countries. The authors of this paper developed and proposed eight ideas to be reflected by prospective science teachers or science teacher education providers in educating future science teachers concerned about action competence about sustainable development.

The study discussed in this paper is a systematic literature review related to the role of dual language programme (DLP) in mathematics education which has been published within the last 5 years. This study was conducted to identify the distribution of DLP studies in terms of year of publication, the study context covered in previous studies, the context of study areas used, focus and trends of past studies, research methods used in previous studies and the role of language in school mathematics education. This review study followed the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) to analyze articles from Scopus and Web of Science. The findings of the study indicate that research trends in the implementation of the DLP on mathematics education for secondary school students showed an increase from 2017 to 2019. Most DLP-related articles are widely developed in the United States and Germany. The findings indicate that previous studies are more interested in studying the implementation of DLP in rural areas. Past studies have also preferred to use the design of either a qualitative study or a quantitative study to be implemented. Questionnaires, tests and interviews are among the research instruments that are often used for a study.

Rapid genomic testing (rGT) enables genomic information to be available in a matter of hours, allowing it to be used in time-critical settings, such as intensive care units. Although rGT has been shown to improve diagnostic rates in a cost-effective manner, it raises ethical questions around a range of different areas, including obtaining consent and clinical decision-making. While some research has examined the perspectives of parents and genetics health professionals, the attitudes of intensive care clinicians remain under-explored. To address this gap, we administered an online survey to English-speaking neonatal/paediatric intensivists in Europe, Australasia and North America. We posed two ethical scenarios: one relating to obtaining consent from the parents and the second assessing decision-making regarding the provision of life-sustaining treatments. Descriptive statistics were used to analyse the data. We received 40 responses from 12 countries. About 50–75% of intensivists felt that explicit parental consent was necessary for rGT. About 68–95% felt that a diagnosis from rGT should affect the provision of life-sustaining care. Results were mediated by intensivists' level of experience. Our findings show divergent attitudes toward ethical issues generated by rGT among intensivists and suggest the need for guidance regarding ethical decision-making for rGT. [ABSTRACT FROM AUTHOR]

The management of atrial fibrillation (AF), the most common sustained arrhythmia, impacts healthcare resource utilization (HCRU). This study aims to estimate global resource use in AF patients, using the GARFIELD-AF registry. A prospective cohort study was conducted to characterize HCRU in AF patients enrolled in sequential cohorts from 2012 to 2016 in 35 countries. Components of HCRU studied were hospital admissions, outpatient care visits, and diagnostic and interventional procedures occurring during follow-up. AF-related HCRU was reported as the percentage of patients demonstrating at least one event and was quantified as rate-per-patient-per-year (PPPY) over time. A total of 49,574 patients was analyzed, having an overall median follow-up of 719 days. Almost all patients (99.5%) had at least one outpatient care visit, while hospital admissions were the second most frequent medical contact, with similar proportions in North America (37.5%) and Europe (37.2%), and slightly higher in the other GARFIELD-AF countries (42.0%; namely Australia, Egypt, and South Africa). Asia and Latin America showed lower percentages of hospitalizations, outpatient care visits, and diagnostic and interventional procedures. Analyses of GARFIELD-AF highlighted the vast AF-related HCRU, underlying significant geographical differences in the type, quantity, and frequency of AF-related HCRU. These differences were likely attributable to health service availability and differing models of care. [ABSTRACT FROM AUTHOR]

Research on augmented reality (AR) in education is gaining momentum worldwide. This field has been actively growing over the past decades in terms of the research and development of new technologies. Reviews in the field of AR in education consist of systematic literature reviews and meta-analyses (around 45), surveys (around 33), and only one bibliometric analysis. However, these reviews do not provide a general synthesis of the research published in the field to depict its evolution over the years. This study used the metadata of articles from a 25-year period (1995-2020) to conduct a bibliometric analysis. A total of 3,475 studies were considered. In this study, we used tools such as the Scopus database, the bibliometrix R package, and the VOSviewer analysis tool. The analysis of the literature is based on the metadata, author, content, and citation information extracted from the dataset. In addition, we focus on comparing literature published mainly in journals (articles, articles in press, and reviews) and those published in other sources (conference papers, books, and book chapters). Practitioners could use the results of this study to make decisions about the adoption of AR technologies in education.

This article will analyse factors which, since the end of last century, have made interregional relations very important to understand the world geopolitical and economic order. Interregional relations are defined as those which pertain to relations between regions or between a given state and a given region, or within a megaregion. This evolution results from: the growing demand in the emerging economies and the interaction among them, a new framework of interregional economic relations, and the development of new commercial channels. Finally, this paper will introduce the different articled included in this issue. [ABSTRACT FROM AUTHOR]

• Background and Aims Many Orchidaceous species are threatened globally by development and over-collection from their natural habitats for horticultural purposes. Artificial propagation from seeds is difficult in most terrestrial orchids native to temperate regions. Seed production is another limiting factor in the artificial propagation for these species because of the lessened probability of pollination and the destruction of fruit by insect larvae. Members of the genus Cephalanthera are distributed across Europe, Asia and North America. C. falcata is a temperate species of East Asia and an endangered species in Japan. As successful propagation from seeds of this species has never been reported, a reproducible method is described here for seed production in situ and propagation using immature seeds in asymbiotic culture in vitro.

Understanding the climate change processes requires application of special methodologies for revealing a ground surface temperature history (GSTH). It was proved by different authors that the GSTH may be determined on the basis of analysis of the temperature field observed in short boreholes. In this paper, the authors analyze four mathematical models describing the GSTH: (1) sudden change, (2) linear increase, (3) square root of time increase and (4) exponential increase. Fifteen borehole temperature profiles from Europe, Asia and North America were selected in three groups based on their geographical proximity. After careful analysis of temperature-depth profiles in these boreholes it was found out that two models (linear increase and square root of time increase) provide the best fit with field data. The calculated warming rates in the 20th century were compared with those obtained by a few parameters estimation (FPE) technique. [ABSTRACT FROM AUTHOR]

The purpose of this paper is to centralize and amplify LGBTQ international educators' voices on how to expand school inclusivity to consider their complex realities. Seventeen LGBTQ international educators were interviewed as to what recommendations they would make to school leaders that could improve work situations for LGBTQ international staff and to future LGBTQ international educators who seek a global career. An analysis of the recommendations revealed four themes in the data: pre-departure preparation, finding community, cultural navigation, and school leadership. A core finding is that sexuality and gender are not neutral in international schools and that LGBTQ international educators require different kinds of support than their cisgender, heterosexual counterparts.

The meta-analysis described in this paper evaluated the relationships between 11 types of leadership practices and 7 organizational, teaming, leader, and employee outcomes. A main focus of analysis was whether the leadership practices were differentially related to the study outcomes. Studies were eligible for inclusion if the correlations between leadership subscale measures (rather than global measures of leadership) and outcomes of interest were reported. The random effects weighted average correlations between the independent and dependent measures were used as the sizes of effects for evaluating the influences of the leadership practices on the outcome measures. One hundred and twelve studies met the inclusion criteria and included 39,433 participants. The studies were conducted in 31 countries in different kinds of programs, organizations, companies, and businesses. Ninety-six percent of the practice-outcome effect sizes were statistically significant where approximately half of the relationships were moderated by organizational types (for-profit, not-for-profit, education, healthcare, government, etc.). Results indicated that the 11 types of leadership practices were differentially related to the study outcomes even in the presence of considerable between study heterogeneity.

This study investigated the places of origin of international students and their distribution in the United States higher education. The data concerning the population of international students were obtained from the official website of International Institution of Education (IIE), and transferred into three maps using geographic information systems (GIS) software so that a more direct view of the data was available. The results of the study showed that (1) A larger proportion of international students come from Asian countries; (2) California, New York, and Texas are the top three states hosting international students; (3) most of the universities enrolling international students are located in the eastern part of the country; and (4) the states with already large international student populations experienced a faster growth in the population of international students over the past five years. Some implications for policy planning are discussed at the end of this paper.

Recent studies by Adelman and by Friedlander and Silver, which have investigated whether regression equations derived from cross-section data can be used to predict the impact of socioeconomic development on changing levels of fertility, are reviewed critically. Regression analyses based on data for 57 countries c. 1960 show that fertility (gross reproduction rate) varies cross-sectionally with region as well as with level of development (as measured by per capita income, percent labor force in primary sector, expectation of life, illiteracy rate). Using equations derived from the cross-section study and time-series data for five European countries during the period that their fertility rates fell, it is shown that predictions about past fertility changes are in error. The results suggest caution in the use of cross-section relations to predict the course of fertility in developing countries. [ABSTRACT FROM AUTHOR]

Teacher agency (TA) has been increasingly supported as an influential factor for teacher professional learning, school improvement and sustainable educational change. Previous studies, however, feature a variety of discrepancies in their conceptualisation and approaches to examining teacher agency. A systematic review is essential to map the field, refine our understanding of the concept and inform relevant stakeholders of useful insights for policy making and further research. After being screened against a number of inclusion criteria, 104 empirical studies were selected to be included in this review. Thematic analysis was adopted for the data analysis of these papers. Findings indicate an imbalance in geographical, theoretical, methodological and thematic distributions in previous studies. Six major themes were identified from the literature: (1) TA enactment, (2) the role of teacher cognition, (3) influential factors, (4) implementing professional development interventions, (5) TA outcomes and (6) TA change trajectory. TA can be extrapolated in terms of its source, enactment and outcomes. Teachers' capacities, implementation strategies, and contextual factors jointly determine the achievement of their professional agency. A conceptual framework for accounting teacher agency holistically is proposed and implications for relevant stakeholders are discussed.

Background: SARS-CoV-2 is a RNA coronavirus responsible for the pandemic of the Severe Acute Respiratory Syndrome (COVID-19). RNA viruses are characterized by a high mutation rate, up to a million times higher than that of their hosts. Virus mutagenic capability depends upon several factors, including the fidelity of viral enzymes that replicate nucleic acids, as SARS-CoV-2 RNA dependent RNA polymerase (RdRp). Mutation rate drives viral evolution and genome variability, thereby enabling viruses to escape host immunity and to develop drug resistance.Methods: We analyzed 220 genomic sequences from the GISAID database derived from patients infected by SARS-CoV-2 worldwide from December 2019 to mid-March 2020. SARS-CoV-2 reference genome was obtained from the GenBank database. Genomes alignment was performed using Clustal Omega. Mann-Whitney and Fisher-Exact tests were used to assess statistical significance.Results: We characterized 8 novel recurrent mutations of SARS-CoV-2, located at positions 1397, 2891, 14408, 17746, 17857, 18060, 23403 and 28881. Mutations in 2891, 3036, 14408, 23403 and 28881 positions are predominantly observed in Europe, whereas those located at positions 17746, 17857 and 18060 are exclusively present in North America. We noticed for the first time a silent mutation in RdRp gene in England (UK) on February 9th, 2020 while a different mutation in RdRp changing its amino acid composition emerged on February 20th, 2020 in Italy (Lombardy). Viruses with RdRp mutation have a median of 3 point mutations [range: 2-5], otherwise they have a median of 1 mutation [range: 0-3] (p value < 0.001).Conclusions: These findings suggest that the virus is evolving and European, North American and Asian strains might coexist, each of them characterized by a different mutation pattern. The contribution of the mutated RdRp to this phenomenon needs to be investigated. To date, several drugs targeting RdRp enzymes are being employed for SARS-CoV-2 infection treatment. Some of them have a predicted binding moiety in a SARS-CoV-2 RdRp hydrophobic cleft, which is adjacent to the 14408 mutation we identified. Consequently, it is important to study and characterize SARS-CoV-2 RdRp mutation in order to assess possible drug-resistance viral phenotypes. It is also important to recognize whether the presence of some mutations might correlate with different SARS-CoV-2 mortality rates. [ABSTRACT FROM AUTHOR]

Background: Recent data suggest that the risk of young-onset colorectal cancer (yCRC), in adults less than 50 years of age, is increasing. To confirm findings and identify contemporary trends worldwide, we conducted a systematic review of studies examining population-level trends in yCRC epidemiology.Methods: We searched MEDLINE (1946-2018), EMBASE (1974-2018), CINAHL (1982-2018), and Cochrane Database of Systematic Reviews (2005-2018) for studies that used an epidemiologic design, assessed trends in yCRC incidence or prevalence, and published in English. Extracted information included country, age cut-off for yCRC, and reported trends in incidence or prevalence (e.g. annual percent change [APC]). We pooled similarly reported trend estimates using random effects models.Results: Our search yielded 8695 articles and after applying our inclusion criteria, we identified 40 studies from 12 countries across five continents. One study assessed yCRC prevalence trends reporting an APCp of + 2.6 and + 1.8 among 20-39 and 40-49 year olds, respectively. 39 studies assessed trends in yCRC incidence but with substantial variability in reporting. Meta-analysis of the most commonly reported trend estimate yielded a pooled overall APCi of + 1.33 (95% CI, 0.97 to 1.68; p < 0.0001) that is largely driven by findings from North America and Australia. Also contributing to these trends is the increasing risk of rectal cancer as among 14 studies assessing cancer site, nine showed an increased risk of rectal cancer in adults less than 50 years with APCi up to + 4.03 (p < 0.001).Conclusions: Our systematic review highlights increasing yCRC risk in North America and Australia driven by rising rectal cancers in younger adults over the past two decades.
