Purpose: To assess how previous experiences and new information contributed to COVID-19 vaccine intentions.
Design: Online survey (N = 1264) with quality checks.
Setting: Cross-sectional U.S. survey fielded June 22-July 18, 2020.
Sample: U.S. residents 18+; quotas reflecting U.S. Census, limited to English speakers participating in internet panels.
Measures: Media literacy for news content and sources, COVID-19 knowledge; perceived usefulness of health experts; if received flu vaccine in past 12 months; vaccine willingness scale; demographics.
Analysis: Structural equation modelling.
Results: Perceived usefulness of health experts ( = .422, < .001) and media literacy ( = .162, < .003) predicted most variance in vaccine intentions (R-squared=31.5%). A significant interaction ( = .163, < .001) between knowledge ( = -.132, = .052) and getting flu shot ( = .185, < .001) predicted additional 3.5% of the variance in future vaccine intentions. An increase in knowledge of COVID-19 associated with a decrease in vaccine intention among those declining the flu shot.
Conclusion: The interaction result suggests COVID-19 knowledge had a positive association with vaccine intention for flu shot recipients but a counter-productive association for those declining it. Media literacy and trust in health experts provided strong counterbalancing influences. Survey-based findings are correlational; thus, predictions are based on theory. Future research should study these relationships with panel data or experimental designs.

Efficacy of the Foodbot Factory digital curriculum-based nutrition education intervention in improving children's nutrition knowledge, attitudes and behaviours in elementary school classrooms: protocol for a cluster randomised controlled trial.

Introduction: Schools are an important setting for supporting children's development of food literacy, but minimal research has assessed which strategies are most suitable for school nutrition education. The Foodbot Factory intervention, consisting of serious game (ie, a digital game designed for education) and curriculum-based lesson plans, was developed to support teachers and children ages 8-12 with nutrition education. Pilot data have demonstrated that Foodbot Factory can significantly improve children's nutrition knowledge, but it has not yet been evaluated in classrooms.

Background: Although artificial intelligence (AI) has gained increasing attention for its potential future impact on clinical practice, medical education has struggled to stay ahead of the developing technology. The question of whether medical education is fully preparing trainees to adapt to potential changes from AI technology in clinical practice remains unanswered, and the influence of AI on medical students' career preferences remains unclear. Understanding the gap between students' interest in and knowledge of AI may help inform the medical curriculum structure.

The digitalization of society increasingly blurs boundaries between analog and digital worlds, offering opportunities such as telemedicine and global connectivity through digital platforms. However, it also presents risks, including cyberbullying, addiction potential, harmful content, misinformation, and privacy concerns from data breaches and surveillance technologies. Social media, with its global reach, amplifies both opportunities for positive engagement and the responsibility to navigate largely unregulated content.

Defining quantum games.

In this research article, we survey existing quantum physics-related games and, based on this survey, propose a definition for the concept of quantum games. We define a quantum game as any type of rule-based game that either employs the principles of quantum physics or references quantum phenomena or the theory of quantum physics through any of three proposed dimensions: the perceivable dimension of quantum physics, the dimension of quantum technologies, and the dimension of scientific purposes, such as citizen science or education. We also discuss the concept of quantum computer games, which are games on quantum computers, as well as definitions for the concept of science games.
