This paper provides an account of the topological and its description of contemporary culture and use as a research methodology, a topological lens, generally, and in education research specifically. Some commentary is proffered on the relationships between the topological and the topographical, between relations and locations. A critical account is then provided on each of the papers in the special issue on the topological in education research and the specific contributions of each. The editors of the special issue make the important point that the topological is a spatio-temporal phenomenon, not just a spatial one. The topological does not exist in time and space, but rather constructs both and they change in a conjoint manner. As such, a topological lens rejects a construction of space as static and of time (and the temporal) as simply linear and chronological. The topological has been facilitated and articulated by and through practices of commensuration, datafication and digitalisation, flows and scapes, global connectivities and new relations, mobilities of various kinds and multiple networks. The paper argues that much greater emphasis has been given to the spatial in topological research; that is, there has been some neglect of the temporal in the spatio-temporal character of topologies.

This study aims to examine the effects of flipped learning on L2 students' overall academic achievements through meta-analysis. Forty studies (e.g., journal articles, M.A/Ph.D. theses and conference papers) on 'flipped classroom', 'flipped learning' and 'academic achievement' were included in this meta-analysis study. The data was analyzed by using Comprehensive Meta-Analysis Software. The random effects model was used in analyzing the overall effect size and the heterogeneity of the studies included in this meta-analysis. The results revealed that flipped learning has statistically significant effect on L2 learners' academic achievements (g=1.303) compared to traditional learning approaches. This result does not differ according to publication type, educational level and four basic language skills and sub-skills, but it differs according to sample size of the selected studies.

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.

Online platforms can support health and educational professionals in their daily work; however, it is challenging to keep online platforms sustainable. This paper aims to indicate the most important factors of platform sustainability from the perspective of professionals involved in online platforms. Further, it aims to understand how these factors operate. A mixed methods study was carried out among professionals from Europe, Australia, the USA and Canada. In the first phase, the importance of 54 factors from the literature was assessed with a questionnaire among 17 professionals. The relative importance of the factors and the consensus regarding this importance were calculated using median scores and interquartile deviations. In total, 19 factors were selected representing general characteristics, characteristics related to the platform, communication, visitor and context. In the second phase, insight was gained regarding the experiences with those factors through 12 individual Skype interviews. The most frequently mentioned important factors of platform sustainability were (i) having sufficient time, resources and expertise, (ii) user friendliness and (iii) creating a sense of belonging. Platforms should use a planned approach to address a combination of factors directly from platform development. Gaining long-term resources is challenging and should be considered from the start of a project by building partnerships. To promote user friendliness, platforms should be simple, have a clear set-up and provide high-quality tools. Finally, establishing a sense of belonging could be supported by branding and face-to-face networking activities. For all aspects, involving visitors and stakeholders is essential.

Introduction: The World Health Organization identified health to be the most important social goal and the 1978 Declaration of Alma Ata placed primary health care central to its attainment and the UN Sustainable Development Goals (SDGs) as the template. The Astana Declaration called on a change of focus in primary care, from treatment of specific diseases to the prevention and inclusion of both scientific and traditional knowledge. Such objectives require public–private partnerships in providing health care, including traditional and complementary medicine systems such as naturopathy that align. However, there is limited understanding of global regulatory frameworks and officially recognized training for naturopathy. Materials and Methods: This descriptive study employs an adapted mixed-methods explanatory framework to examine naturopathy regulation and education. Analysis merges data arising from a descriptive policy analysis of regulation from 36 countries and survey analysis from 65 naturopathic organizations from 29 countries. Results: Four types of workforce regulation were identified within 107 countries where naturopathy was practiced—statutory registration or occupational licensing, coregulation, negative licensing, and voluntary certification. No form of naturopathic regulation was most common. Higher graduate/postgraduate education and access to a broader range of practices were more frequently reported in countries where naturopathy is statutory regulated. Government audits were more frequently reported where naturopathy was statutory regulated or coregulated. Discussion: Naturopathic philosophy and practice align with primary health care goals outlined in the Declaration of Astana. The naturopathic workforce represents an untapped health care resource with a demonstrated track record of translating these aspirational goals into practice. However, naturopathy remains inconsistently regulated globally, serving as a significant barrier to partnering with other health system actors to attain the health-related SDGs. Workforce regulation for the naturopathic profession offers increased standards, reduced risks, integrative health workforce planning, and assistance to countries toward achieving the promise of the Declaration of Astana.

Background: The Double OT (DOT) assessment is occupation-based and dynamic, designed with a clientcentered format requiring skill demonstration. It was developed to support youth transitioning into the workplace. This research intended to analyze initial validity and users' experience. Method: This study includes qualitative and quantitative analyses of data collected from surveys from 169 client participants (APs) and 30 recipient participants (ARRs) from eight sites in the USA and Europe. AP were 14 to 25 years of age and engaged in residential, educational, and vocational settings. The ARRs comprised partners who had received DOT assessment summaries about APs with whom they worked. Results: The APs showed high engagement and learning; average ratings for each item fell between 4.24-4.54 on a 5-point Likert scale. The ARRs agreed on the validity and usability of the DOT; average ratings for each item fell between 3.75 and 4.53 on a 5-point Likert scale. Qualitative themes indicated that the DOT is: "fun and engaging," "vocationally informative and applicable," and that there is an absence of commonly used assessments informing vocational transitions. Conclusion: The results support initial validity of the DOT. Users find it to be highly engaging, with good usability, and indicate that it facilitates participant learning. [ABSTRACT FROM AUTHOR]

Aim: To develop and validate models based on logistic regression and artificial intelligence for prognostic prediction of molar survival in periodontally affected patients. Materials and Methods: Clinical and radiographic data from four different centres across four continents (two in Europe, one in the United States, and one in China) including 515 patients and 3157 molars were collected and used to train and test different types of machine‐learning algorithms for their prognostic ability of molar loss over 10 years. The following models were trained: logistic regression, support vector machine, K‐nearest neighbours, decision tree, random forest, artificial neural network, gradient boosting, and naive Bayes. In addition, different models were aggregated by means of the ensembled stacking method. The primary outcome of the study was related to the prediction of overall molar loss (MLO) in patients after active periodontal treatment. Results: The general performance in the external validation settings (aggregating three cohorts) revealed that the ensembled model, which combined neural network and logistic regression, showed the best performance among the different models for the prediction of MLO with an area under the curve (AUC) = 0.726. The neural network model showed the best AUC of 0.724 for the prediction of periodontitis‐related molar loss. In addition, the ensembled model showed the best calibration performance. Conclusions: Through a multi‐centre collaboration, both prognostic models for the prediction of molar loss were developed and externally validated. The ensembled model showed the best performance in terms of both discrimination and validation, and it is made freely available to clinicians for widespread use in clinical practice.

The author comments on a study by S. H. Woolf, published in the issue about life expectancy in the U.S. She discusses some caveats on the comparisons presented by Woolf in discussing methodology and data, three of the four causes that Woolf notes are causing midlife mortality to rise in the U.S., and results that do not make a lack of higher education causal in the higher mortality rates for those without a four-year college degree.

This qualitative study explored the experiences of transracial Korean adoptee returnees who were born in Korea, separated from their biological families, raised in the United States and three European countries by White families, and given an Anglicized or Germanic name at the time of their adoption. This study focused on participants' journeys of reclaiming their Korean birth names and the various influences that factored into this decision. Data were collected from in-depth, semi-structured interviews (in-person or via Skype) and coded using grounded-theory methods that integrated a constructivist-interpretivist and critical epistemological paradigm. Participants (N = 12) were transracial Korean adoptees with ages ranging from 22 to 42 years (M = 32.67 years) who were between 0 and 88 months (M = 22.33 months) at the time of adoption, all of whom had returned to Korea. Results from the interviews revealed 11 axial categories and 2 overarching selective categories related to the name reclamation process: (a) name reclamation was part of a larger identity development process; (b) factors that prevented or slowed the name reclamation process. Limitations and future areas of research are discussed. [ABSTRACT FROM AUTHOR]

Objective: To develop and validate classification criteria for microscopic polyangiitis (MPA).Methods: Patients with vasculitis or comparator diseases were recruited into an international cohort. The study proceeded in five phases: (1) identification of candidate items using consensus methodology, (2) prospective collection of candidate items present at the time of diagnosis, (3) data-driven reduction of the number of candidate items, (4) expert panel review of cases to define the reference diagnosis and (5) derivation of a points-based risk score for disease classification in a development set using least absolute shrinkage and selection operator logistic regression, with subsequent validation of performance characteristics in an independent set of cases and comparators.Results: The development set for MPA consisted of 149 cases of MPA and 408 comparators. The validation set consisted of an additional 142 cases of MPA and 414 comparators. From 91 candidate items, regression analysis identified 10 items for MPA, 6 of which were retained. The final criteria and their weights were as follows: perinuclear antineutrophil cytoplasmic antibody (ANCA) or anti-myeloperoxidase-ANCA positivity (+6), pauci-immune glomerulonephritis (+3), lung fibrosis or interstitial lung disease (+3), sino-nasal symptoms or signs (-3), cytoplasmic ANCA or anti-proteinase 3 ANCA positivity (-1) and eosinophil count ≥1×109/L (-4). After excluding mimics of vasculitis, a patient with a diagnosis of small- or medium-vessel vasculitis could be classified as having MPA with a cumulative score of ≥5 points. When these criteria were tested in the validation data set, the sensitivity was 91% (95% CI 85% to 95%) and the specificity was 94% (95% CI 92% to 96%).Conclusion: The 2022 American College of Rheumatology/European Alliance of Associations for Rheumatology classification criteria for MPA are now validated for use in clinical research.
