The current study aimed to test the validity of an extended theory of planned behavior model (TPB; Ajzen, 1991), incorporating additional self and social influences, for predicting adolescent moderate-to-vigorous physical activity. Participants (N = 423) completed an initial questionnaire that assessed the standard TPB constructs of attitude, subjective norm, and perceived behavioral control, a...

The utility of food traceability standards aims to reduce the of food security and to provide consumers with targeted information. A survey has been conducted on sample of consumers in Beijing (n = 234), aiming to explain the intention toward purchasing traceable beef using the theory of planned behavior (TPB). Based on the TPB, the present study has added new variable: past experience. Structu...

Current dialogues across a variety of disciplines from the social, behavioral and computer sciences have made clear the need for authentic, repeatable and actionable social simulations. Understanding how the individuals that comprise various populations (and segments of society) might respond to a given set of conditions provides the potential to better inform analysts and decision makers in a ...

A resonance light scattering technique to determine tinidazole in drugs was developed by tetraphenylboron sodium (TPB). Tinidazole was found to bind B(C(6)H(5))(-) (4) anion and transformed to tinidazole-TPB aggregate which displayed intense resonance scattering light. Effects of factors such as wavelength, acidity, stabilizers, and interferents on the RLS of tinidazole TPB were investigated in...

This study tested the utility of the Theory of Planned Behaviour (TPB) to predict mothers' decisions to ensure their child engages in sun-protective behaviours. Mothers (N = 162) of children aged four or five years completed standard TPB items (attitude, subjective norm, perceived behavioural control, intention) and additional variables of role construction, mothers' own sun safe behaviour, pla...
