Objectives: This paper aims to systematically review the impact of legislative framework changes in North America and Europe on adolescent cannabis use. It not only seeks to examine the prevalence of adolescent marijuana use following legislative changes but also to identify the driving forces behind fluctuations in use and to address the gaps left by previous studies. Methods: A systematic literature review was conducted in selected databases. After screening English-language publications dating from 2013 to 2023 (n = 453 studies), 24 met the inclusion criteria. Articles were considered if they analyzed the impact of legislative changes on adolescent cannabis use in countries across North America and Europe. Synthesis: The overall findings suggest an inconsistency regarding the prevalence of cannabis use among youth and adolescents following policy changes. The effects of modifications in cannabis policies on marijuana consumption are complex and influenced by various factors. These include the details of legislation, societal perspectives, enforcement methods, socioeconomic status, and cultural background. Conclusions: The results of this analysis reveal a nuanced reality. Although research suggests a rise in cannabis use after legalization, there are variations in the outcomes observed. This highlights the significance of considering context and demographics. Moreover, studies shed light on how specific policy changes, such as depenalization, can affect cannabis use.

Asexuality studies are an emerging field in North America and Europe which lack large-scale, qualitative studies. Much existing research focuses on defining and categorizing asexuality, with researchers calling for more focus on the romantic and sexual relationships of asexual people. Drawing from an online survey with 349 participants, this paper describes the perceptions and experiences that asexual people have with dating and relationships. Participants answered 16 open-ended and 9 close-ended questions. After rounds of coding, three themes were selected for examination. These were dating, romantic and/or sexual relationships, and platonic relationships. These results showcase the challenges asexuals face with dating while also demonstrating how asexual people actively dismantle understandings of romantic, sexual, and platonic relationships through their own experiences and perspectives. Overall, this study provides greater legitimacy to the fluidity of asexuality and asexual relationships. [ABSTRACT FROM AUTHOR]

Background: Parents play a central role in the treatment of childhood stuttering. Addressing parental attitudes toward stuttering is helpful therapeutically. The extent to which differences in attitudes toward stuttering exist on the basis of sex, geographical region and parental status (e.g., parent of a stuttering child, parent of a nonstuttering child, nonparent) is unclear. Many studies investigating such factors have used the Public Opinion Survey of Human Attributes–Stuttering (POSHA–S) questionnaire. A large POSHA–S database has collected responses from over 20 000 people from 49 countries. Aims: The aim of this study was to use the POSHA‐S database to examine the extent to which the following variables influence attitudes toward stuttering: (a) parents' sex (mothers vs. fathers), (b) geographic region (Middle East vs. Europe and North America), (c) parents' children (stuttering vs. nonstuttering) and (d) parental status (parents versus nonparents). Methods & Procedures: Data used in this study were extracted from selected, relevant studies that administered the POSHA–S to respondents. The Overall Stuttering Scores were compared on the basis of sex and parent status (i.e., mothers and fathers; nonparent women and men) and were then compared within and across the two geographical areas. Group comparisons were performed using analysis of variance followed by independent t tests, and Cohen's d was calculated to determine effect sizes. Outcomes & Results: Statistically significant differences were observed upon the basis of geographical region. In general, male parents and nonparents tend to have more positive stuttering attitudes among the Middle Eastern samples while female parents and nonparents tend to show more positive attitudes in European and North American samples in the POSHA–S database. Effect sizes were small for all comparisons. Conclusions & Implications: The effect of geographic region and culture may predict sex‐based differences among mothers' and fathers' attitudes toward stuttering; however, the clinical significance is unclear. Additional research is needed to better understand how children who stutter are affected by their parents' attitudes toward stuttering. What this paper adds: What is already known on this subject: The research clearly indicates that attitudes toward stuttering vary according to geographical region. Less clear is whether mothers and fathers from geographically diverse backgrounds hold different attitudes toward stuttering and the extent to which parental status (being a parent, parent of a child who stutters or nonparent) affects attitudes toward stuttering. What this study adds: This study's findings confirm that geographical differences do influence attitudes toward stuttering. Male parents and nonparents tend to have equal or more positive attitudes toward stuttering in Middle Eastern samples, whereas non‐Middle Eastern female parents and nonparents tend to show hold more positive attitudes. What are the clinical implications of this work?: In addition to being culturally sensitive when working with parents of children who stutter, clinicians should also consider that mothers and fathers may have some differences in attitudes and behaviours toward their child's stuttering. These differences should be considered when designing treatment plans. It should also be noted that, despite statistical significance, the effect sizes in this study were low, suggesting that further research as well as close collaboration with parents of children who stutter is warranted.

A recent renaissance of industrial hemp has been driven by a plethora of ecologically amicable products and their profitability. To identify its environment and economic fate across the value chain (VC), this study conducts a systematic review of 98 studies published in ScienceDirect, Web of Science, and Scopus‐indexed journals. The thematic content of the articles is categorized using three deductively derived classification categories: lifecycle analysis (n = 40), VC analysis (n = 30), and feasibility analysis (n = 28). Bibliometric analysis indicates that the majority (>90%) of the studies were conducted in selected regions of Europe or North America, with further findings around regionally prioritized industrial hemp products, such as hempcrete in Southwest Europe, solid biofuel in North European states, and textile fiber and bio‐composites in East Europe and North America. Lifecycle analysis studies highlight nitrogenous fertilizer use during industrial hemp cultivation as a major ecological hotspot, which is taking a toll on the climate change index. However, hemp‐based products are generally climate‐friendly solutions when contrasted against their fossil fuel counterparts, with hempcrete in particular a highly touted carbon‐negative (−4.28 to −36.08 kg CO2 eq/m2) product. The review also identifies key issues within the hemp VC and presents innovative solutions alongside the recognition of value‐adding opportunities. Furthermore, feasibility analysis indicates unprofitability in using hemp for bioenergy production and there is a relative cost worthiness of hemp bio‐composites and hempcrete at the upstream level. Positive returns are observed under co‐production schemes. In contemplating the literature findings, we discussed and identified gap in existing literature for future exploration, including more studies to provide insights from the Global South, and the production of industrial hemp under a biophysically constrained landscape.

Background: Physical inactivity is a major public health concern, exacerbated in countries with a (sub)tropical climate. The built environment can facilitate physical activity; however, current evidence is mainly from North American and European countries with activity-friendly climate conditions. This study explored associations between built environment features and physical activity in global tropical or subtropical dry or desert climate regions. Methods: A systematic review of four major databases (Web of Science, Scopus, PubMed, and SportDISCUS) was performed. To be included, studies had to investigate associations between perceived or objective built environment characteristics and adult's physical activity and had to be conducted in a location with (sub)tropical climate. Each investigated association was reported as one case and results were synthesized based upon perceived and objectively assessed environment characteristics as well as Western and non-Western countries. Study quality was evaluated using a tool designed for assessing studies on built environment and physical activity. Results: Eighty-four articles from 50 studies in 13 countries with a total of 2546 built environment-physical activity associations were included. Design (connectivity, walking/cycling infrastructure), desirability (aesthetics, safety), and destination accessibility were the built environment characteristics most frequently associated with physical activity across the domains active transport, recreational physical activity, total walking and cycling, and moderate-to-vigorous physical activity, particularly if multiple attributes were present at the same time. Very few studies assessed built environment attributes specifically relevant to physical activity in (sub)tropical climates. Most studies were conducted in Western countries, with results being largely comparable with non-Western countries. Findings were largely generalizable across gender and age groups. Results from natural experiments indicated that relocating to an activity-friendly neighborhood impacted sub-groups differently. Conclusions: Built environment attributes, including destination accessibility, connectivity, walking and cycling infrastructure, safety, and aesthetics, are positively associated with physical activity in locations with (sub)tropical climate. However, few studies focus on built environment attributes specifically relevant in a hot climate, such as shade or indoor recreation options. Further, there is limited evidence from non-Western countries, where most of the urban population lives in (sub)tropical climates. Policy makers should focus on implementing activity-friendly environment attributes to create sustainable and climate-resilient cities. [ABSTRACT FROM AUTHOR]

Background: Oral disorders are still a major global public health challenge, considering their perpetuating and chronic nature. Currently, there is no direct index to measure the quality of care on a population scale. Hence, we aim to propose a new index to measure the quality of care for oral disorders worldwide. Methods: We generated our database using the data from the Global Burden of Disease (GBD) study 2017. Among different variables such as prevalence, incidence, years lived with disability, and disability-adjusted life years, we utilised principal component analysis (PCA) to determine the component that bears the greatest proportion of information to generate the novel quality of care index (QCI) for oral disorders. Results: Global QCI for oral disorders gradually increased from 1990 to 2017 (from 70.5 to 74.6). No significant gender disparity was observed during this period, and the gender disparity ratio (GDR) was considered optimal in 1990 and 2017. Between 1990 and 2017, the age-standardised QCI for all oral disorders increased in all the SDI regions. The highest QCI for all oral disorders in 2017 belonged to high-middle SDI countries (=80.24), and the lowest YLDs rate was seen in the low SDI quintile. In 1990, the quality of care in European, Central Asian, and Central and South American countries was in the lowest quintiles, whereas the North American, East Asian, Middle Eastern, and some African countries had the highest quality of dental care. Maynmar (=100), Uganda (=92.5), Taiwan (=92.0), China (=92.5), and the United States (=89.2) were the five countries with the highest age-standardised QCI. Nicaragua (=41.3), Belgium (=40.2), Venezuela (=38.4), Sierra Leone (=30.5), and the Gambia (=30.3) were the five countries with the least age-standardised QCI values. Conclusion: The quality of care for all oral disorders showed an increasing trend on a global scale from 1990 to 2017. However, the QCI distribution was not homogenous among various regions. To prevent the exacerbation of imminent disparities in this regard, better attention to total tooth loss in high-income countries and prioritising primary healthcare provision in low-income countries are recommended for oral disorders.

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]

Literature presents evidence of the exponential rise of distributed leadership both as a focus of research and as leadership development in education in the twenty first century (Hairon, S., and J. W. Goh. 2015. "Pursuing the Elusive Construct of Distributed Leadership: Is the Search Over?" "Educational Management Administration & Leadership" 43 (5): 693-718; Hall, D. 2013. "The Strange Case of the Emergence of Distributed Leadership in Schools in England." "Educational Review" 65: 467-487), in addition to the growing criticism of the theory's dominance and its 'acquired taken-for-granted status' (Lumby, J. 2016. "Distributed Leadership as Fashion or fad." "Management in Education" 30 (4): 161-167). This paper thus seeks to provide a systematic review of the literature on distributed leadership published between 2010 and 2022 through a methodical collection, documentation, scrutiny, and critical analysis of the research publications. The review seeks to identify trends in distributed leadership knowledge production according to the study type/purpose, topical foci, methodological approach, focus group, and geographic distribution via a narrative synthesis approach (Oplatka, I., and K. Arar. 2017. "The Research on Educational Leadership and Management in the Arab World Since the 1990s: A Systematic Review." "Review of Education" 5 (3): 267-307).

Across the world, numerous students are being bullied at school. Bullying is often caused by a power imbalance between students. Therefore, identifying potential sources of such a power imbalance can prevent school bullying from happening. Based on the labelling theory, we expect that grade retention can lead to such a power imbalance and, therefore, increase the likelihood of being bullied at school. Hence, this study examines the association between grade retention and self-reported victimisation. We also expect that retainees will be less likely to become a victim of school bullying in schools and countries with a high number of other retainees. If true, this would signal a moderating effect of both school- and country retention composition on the association between grade retention and victimisation. The contextualised impact of grade retention upon victimisation is assessed by cross-national multilevel analyses on PISA2018 data (25 countries; 8,039 schools; 159,412 students). Overall, our findings indicate that being retained in primary and/or secondary education is associated with higher levels of victimisation, while retainees suffer from more victimisation in countries with a low number of other retainees. In contrast to our expectations, however, we did not find such a moderation effect of school retention composition.

Purpose: This systematic review paper aims to examine extant empirical research involving educational technology during COVID-19 to provide an aggregated analysis of how the pandemic has influenced educational technology research. Design/methodology/approach: Using a Preferred Reporting Items for Systematic Reviews and Meta-Analysis systematic review and an integrative review methodology, 50 primary research studies were selected from ten top-ranked educational research journals. These studies were reviewed regarding research purposes, methodologies, instruments, educational level, geographical distribution, and findings of the studies. Findings: The findings reveal four emerging themes--influencing factors, effectiveness, challenges and teachers. The majority of the studies focused on higher education. Quantitative research design based on a questionnaire was the most adopted method of investigation by researchers. Research limitations/implications: Search parameters focused on the top 10 journals in the field of educational technology. Although this provides a level of quality, it narrowed the search. Practical implications: For practitioners and researchers, this study provides a summary of the field to better understand what knowledge we have gained on the use of educational technology to enable a more agile, knowledgeable response to education in future emergencies. Originality/value: This systematic review is unique in examining how the pandemic has influenced educational technology research. It also provides insight into gaps in the research that future researchers can use as a springboard to enable a more knowledge and a more agile approach to future emergencies.
