This paper highlights the distinction between precursor and control variables in the context of reasoned action theory. Here the theory is combined with structural equation modeling to demonstrate how age and past sexual behavior should be situated in a reasoned action analysis. A two wave longitudinal survey sample of African-American adolescents is analyzed where the target behavior is having vaginal sex. Results differ when age and past behavior are used as control variables and when they are correctly used as precursors. Because control variables do not appear in any form of reasoned action theory, this approach to including background variables is not correct when analyzing data sets based on the theoretical axioms of the Theory of Reasoned Action, the Theory of Planned Behavior, or the Integrative Model.

Background: Patients hospitalized outside of monitored environments may experience sudden clinical worsening requiring transfer to the Intensive Care Unit. Early detection based on the clinical nurse's identification of the risk of clinical deterioration represents an opportunity to prevent serious adverse events. Nurse worry is defined as the use of clinical reasoning combined with intuition that precedes the patient's clinical deterioration.

How do we make sense of our surroundings? A widely recognized field in cognitive psychology suggests that many important functions like memory of incidents, reasoning, and attention depend on the way we segment the ongoing stream of perception (Zacks & Swallow, 2007). An open question still is, how the structure generated from a perceptual stream translates into behavior. To address this question, we combined the findings in event segmentation literature with another influential body of literature that analyzes mechanisms behind the control of individual actions (Frings et al.

Autonomous driving has demonstrated impressive driving capabilities, with behavior decision-making playing a crucial role as a bridge between perception and control. Imitation Learning (IL) and Reinforcement Learning (RL) have introduced innovative approaches to behavior decision-making in autonomous driving, but challenges remain. On one hand, RL's policy networks often lack sufficient reasoning ability to make optimal decisions in highly complex and stochastic environments.

The cockpit is evolving from passive, reactive interaction toward proactive, cognitive interaction, making precise predictions of driver intent a key factor in enhancing proactive interaction experiences. This paper introduces Cockpit-Llama, a novel language model specifically designed for predicting driver behavior intent. Cockpit-Llama predicts driver intent based on the relationship between current driver actions, historical interactions, and the states of the driver and cockpit environment, thereby supporting further proactive interaction decisions.

Background: Long-acting injectable (LAI) antiretroviral medications are as effective as daily oral antiretroviral therapy (ART) and offer discreet, less frequent dosing. LAIs may be ideal treatment options for people who experience challenges with adherence to daily oral ART, including mobile men living with HIV (MLHIV).
Methods: We conducted a qualitative substudy within two parent trials in 24 health facilities in Malawi that enrolled MLHIV ≥15 years not on ART.
