Comparison of linear and undulating periodization resistance training on athletic capacities and health promotion: A systematic review and meta-analysis
Objective: This study aims to compare the effects of linear periodization (LP) and undulating periodization (UP) resistance training on athletic ability, body composition, blood lipid, and blood glucose. Methods: We searched PubMed, Embase, Scopus, and Web of Science to collect relevant studies comparing the health-promoting effects of LP and UP up to July 20th, 2025. Two authors independently extracted and coded the data. The TESTEX Scale was em…

Cruise service quality improvement: A quality function deployment approach with online reviews by large language models
Over the past decade, although the global demand for cruise tourism has steadily increased, a decline in customer satisfaction has also emerged as a significant challenge. Quality function deployment (QFD) is an effective approach for transforming customer requirements into product or service quality characteristics, which helps to identify key customer needs and optimize service quality. Therefore, this study aims to apply the QFD model to provi…
Revolving School Doors? A Longitudinal Examination of Teacher, Administrator, and Staff Contributions to School Churn
Non-teaching staff comprise over half of all school employees, and their turnover may be consequential for school operation, culture, and student success, yet we lack evidence documenting their attrition. We use 17 years (2007–2023) of administrative data from Oregon to examine mobility and exit among teachers, administrators, paraprofessionals, licensed staff, and non-licensed staff. Although teacher turnover dominates turnover conversations, te…
Analysis and prediction of disease burden related to opioid use disorder in China based on GBD 2021
Objective: To analyze the disease burden of opioid use disorder (OUD) in China from 1990 to 2021 and predict its future trends. Methods: Annual data from the Global Burden of Disease (GBD 2021) database were used to describe the disease burden through metrics such as prevalence, incidence, mortality, and disability-adjusted life years (DALYs). Joinpoint regression models were employed to analyze trends in disease burden. The estimated annual perc…
Comparison of myopia-related behaviors among Chinese school-aged children and associations with parental awareness of myopia control: A population-based, cross-sectional study
Background In China, approximately 30 and 70% of primary and middle school students, respectively, have myopia, making myopia prevention and control necessary. Eye-use behaviors are closely related to myopia, highlighting the importance of determining the behavioral compliance rates of children. Parental awareness also affects children’s behaviors. Therefore, we assessed the myopia-related behaviors and parental awareness of school-aged children …
Humanizing college online instruction: The effects of professional development on faculty perceptions and instructional practices
The rapid growth of online learning has raised concerns about quality and equity in virtual education. This study introduces the Humanizing Online STEM Academy, a six-week professional development program designed specifically to promote humanizing and inclusive teaching within STEM college online courses. We document in detail the Academy's design and instructional approach, and examine its impact on the perceptions and instructional practices o…

New Teachers in Rural America
How do the characteristics of new teachers vary geographically? In this article, Yujia Liu, Chanh B. Lam, J. Cameron Anglum, and Tuan D. Nguyen use a novel rurality measure, the Community Assets and Relative Rurality (CARR) index, to examine trends in teachers entering the profession across different levels of rurality, focusing on teachers in Kansas and Missouri from 2010 through 2023. They highlight pandemic-era changes in the first-year teache…
Rapid and accurate prediction of cycloplegic refraction in Chinese children: Development and validation of machine learning models
Background: Uncorrected refractive error affects approximately 19 million children globally, resulting in preventable vision loss. However, cycloplegic refraction, the gold standard for assessment, remains largely inaccessible in low-resource settings. We aimed to develop and validate machine learning (ML) prediction models based on non-cycloplegic results to estimate the cycloplegic spherical equivalent (cSE). Methods: The internal dataset compr…

STEM Teacher Characteristics and Mobility: Longitudinal Evidence From the American Midwest, 2010 Through 2023
This study examines the demographics, qualifications, and turnover of STEM teachers in Kansas and Missouri—two contiguous, predominantly rural states in the Midwestern region of the United States. The existing literature lacks detailed insights regarding U.S. STEM teachers, especially with recent economic and social changes over the COVID‐19 pandemic, and there is particularly limited evidence regarding STEM teachers in the U.S. Midwest. Utilizin…

Reducing sweetness expectation in milk tea by crossmodal visuo-auditory interaction
Applying a family stress model to understand U.S. families’ patterns of stress, media use, and child behavior during the Covid-19 pandemic
The COVID-19 pandemic has greatly altered family life, and research among adults and families is finding increases in financial stress, mental health problems, screen time, parental conflict, and child behavior problems. Given these patterns, we sought to replicate these findings with a younger and largely non-white sample and consider how these constructs might relate to each other by using the Family Stress Model. From surveys of 247 predominat…
Data-Driven Eco-Efficiency Analysis and Improvement in the Logistics Industry in Anhui
The ecological efficiency (eco-efficiency) of a regional logistics industry (RLI) is widely regarded as a key factor affecting sustainability of economic development, environmental protection, and resources utilization. This study applied a data-driven method to evaluate and increase the eco-efficiency of an RLI. Based on RLI-related data, which were converted into proper dimensionless indices, data envelopment analysis (DEA), which assumes that …
Association between physical activity dimensions and the risk of hypertension among middle and older adults: A cross-sectional study in China
Background: It is known that insufficient physical activity is associated with the risk of hypertension, but the relationship to different physical activity dimensions within hypertension risk remains to be elucidated. Objective: The objective of this study is to identify the association between physical activity intensity, frequency, duration, and volume with hypertension risk. Meanwhile, a dose-response experiment is conducted to determine the …

Foraging and farming: Archaeobotanical and zooarchaeological evidence for Neolithic exchange on the Tibetan Plateau
Archaeological research has documented the migration of Neolithic farmers onto the Tibetan Plateau by 4000 BC. How these incoming groups interacted, if at all, with local indigenous foragers, however, remains unclear. New archaeobotanical and zooarchaeological data from the Zongri site in the north-eastern Tibetan Plateau suggest that local foragers continued to hunt but supplemented their diet with agricultural products in the form of millet. Th…
The Payoff to Skill in the Third Industrial Revolution
Is the third industrial revolution indeed driven by rising payoffs to skill? This simple but important question has gone unanswered because conventional models of earnings inequality are based on exceedingly weak measurements of skill. By attaching occupational skill measurements to the 1979–2010 Current Population Surveys, it becomes possible to adjudicate competing accounts of the changing returns to cognitive, creative, technical, and social s…
Maternal unemployment and childhood overweight: Is there a relationship
BACKGROUND: Previous studies have shown a positive association between maternal work hours and childhood overweight. However, it is unclear what role job instability plays in this relationship; therefore, this study examined whether children whose mothers experienced unemployment were more likely to have greater increases in body mass index (BMI) as compared with children whose mothers were stably employed. The effects of unemployment benefits, w…
