Background: Threat assessment is a widely recommended practice used by schools to investigate and respond to student threats of violence; however, students are often reluctant to disclose threats.
Methods: We developed an online educational program for students to increase their understanding of threat assessment and the need to report serious threats. We investigated 2 research questions: (1) How are student characteristics of sex, grade level, and ethnicity/race associated with student knowledge of threat assessment and willingness to report threats? (2) Does the program increase knowledge of threat assessment and willingness to report threats? The sample consisted of 2338 students from 6 middle schools and 3 high schools.
Results: Prior to program completion, boys were less willing than girls, and older students were less willing than younger students, to report threats. Post-program questions revealed that the program significantly increased knowledge and willingness to report threats across student groups, with effect sizes (Cohen's d) ranging from small (.30) to large (1.43).
Conclusions: This program promotes school safety by teaching students about threat assessment and increasing willingness to report threats. The program is available online for other schools to use.

Biodiversity encompasses not only species diversity but also the complex interactions that drive ecological dynamics and ecosystem functioning. Still, these critical interactions remain overwhelmingly overlooked in environmental management. In this study, we introduce an ecosystem-based approach that assesses the cumulative effects of climate change and human activities on species in the St.

Background: Occupational burnout, resulting from long-term exposure to work-related stressors, is a significant risk factor for both physical and mental health of employees. Most research on burnout focuses on routine situations, with less attention given to its causes and manifestations during prolonged national crises such as war. According to the Conservation of Resources theory, wartime conditions are associated with a loss of resources, leading to accelerated burnout.

Kelp forests are among the most abundant and productive marine ecosystems but are under threat from climate change and other anthropogenic stressors. Although knowledge is growing about how the abundance and distribution of kelp forests are changing, much less is known about the "non-lethal" effects that global change is having on the performance and health of kelp populations in areas where they persist. Here we assessed the age distribution of two common stipitate kelp species, Laminaria setchelli and Pterygophora californica, at Wizard Islet in Barkley Sound, British Columbia, Canada, and compared these data to historical demographic data collected by De Wreede (1984) and Klinger and DeWreede (1988) from the same site between 1981 and 1983.

Preeclampsia (PE) is a pregnancy-specific disorder characterized by an unclearly understood pathogenesis and poses a great threat to maternal and fetal safety. Cuproptosis, a novel form of cellular death, has been implicated in the advancement of various diseases. However, the role of cuproptosis and immune-related genes in PE is unclear.

Large language models (LLMs) have gained significant attention for their capabilities in natural language understanding and generation. However, their widespread adoption potentially raises public mental health concerns, including issues related to inequity, stigma, dependence, medical risks, and security threats. This review aims to offer a perspective within the actor-network framework, exploring the technical architectures, linguistic dynamics, and psychological effects underlying human-LLMs interactions.
