The analysis of international and collaborative publication trends in prominent behavior‐analytic journals has been a topic of interest for behavioral researchers. This paper focuses on publication trends from 1997 through 2020 in three prominent journals: Journal of the Experimental Analysis of Behavior (JEAB), Journal of Applied Behavior Analysis (JABA), and Perspectives on Behavior Science (PBS). The variable of interest was the percentage of articles published per geographical category—Australasia/East Asia, Europe, Latin America, Middle East, North America, and Africa. The results showed that 79, 96, and 87% of the published articles in JEAB, JABA, and PBS, respectively, were conducted by researchers with a North American affiliation. Furthermore, 12, 4, and 4% of the articles in JEAB, JABA, and PBS, respectively, were coauthored by at least two researchers from different geographical categories. [ABSTRACT FROM AUTHOR]

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.

Numerous studies in different science fields have examined the various aspects of educational interventions designed to facilitate learning outcomes in students with dyslexia. The aim of this study was to present an overview of empirical research related to interventions aimed at primary school students with dyslexia. Mapping was conducted to identify studies on this topic published from 2015 to 2019 and included in the Scopus database. The descriptive data from 57 studies were analyzed to present a classification scheme of research design, type of educational intervention, implementation of technology in educational interventions, and aim of the intervention. The results indicated an increasing trend in the last 5 years in the publication of papers in researched areas related to educational interventions for students with dyslexia, with uneven representation among countries. The analyzed empirical studies were mostly analytic, using different designs, with a slightly higher prevalence of (quasi) experimental versus descriptive designs. As expected, the goal of most educational interventions was directed toward the development of (pre)reading skills, with a wider prevalence of structured language-based programs, followed by software specialized to support learning, whereas adaptations of instructional materials and innovative information and communication technology (ICT) were less used. Mapping indicated the frequent use of ICT in all educational interventions, and more evidence is needed for complex rigorous experimental designs and interventions related to teaching in the classroom, as well as interventions aimed at facilitating the self-regulation of students with dyslexia.

BACKGROUND: Air quality across the northern hemisphere over the past two decades has witnessed dramatic changes, with continuous improvement in developed countries in North America and Europe, but a contrasting sharp deterioration in developing regions of Asia. OBJECTIVE: This study investigates the historical trend in the long-term exposure to PM[sub 2.5] and PM[sub 2.5]-related premature mortality (PM[sub 2.5]-mortality) and its response to changes in emission that occurred during 1990-2010 across the northern hemisphere. Implications for future trends in human exposure to air pollution in both developed and developing regions of the world are discussed. METHODS: We employed the integrated exposure-response model developed by Health Effects Institute to estimate the PM[sub 2.5]-mortality. The 1990-2010 annual average PM[sub 2.5] concentrations were obtained from the simulations using the WRF-CMAQ model. Emission mitigation efficiencies of sulfur dioxide (SO[sub 2]), nitrogen oxides (NO[sub x]), ammonia (NH3), and primary PM are estimated from the PM[sub 2.5]-mortality responses to the emission variations. RESULTS: Estimated PM[sub 2.5]-mortalities in East Asia and South Asia increased by 21% and 85% respectively, from 866,000 and 578,000 in 1990, to 1,048,000 and 1,068,000 in 2010. PM[sub 2.5]-mortalities in developed regions (i.e., Europe and high-income North America) decreased substantially by 67% and 58% respectively. CONCLUSIONS: Over the past two decades, correlations between population and PM[sub 2.5] have become weaker in Europe and North America due to air pollution controls but stronger in East Asia due to deteriorating air quality. Mitigation of primary PM appears to be the most efficient way for increasing health benefits (i.e., providing the largest mortality reduction per unit emissions). However, reductions in emissions of NH[sub 3] are needed to maximize the effectiveness of NO[sub x] emission controls.
