Seeing is believing: How front-of-pack food imagery shapes parents' perceptions of child-oriented snack foods.

Child-oriented snack foods often display front-of-pack images suggesting they are natural or wholesome, yet many of these products are ultra-processed and nutrient poor. This study investigated parent's perceptions in response to common forms of front-of-pack food imagery on child-orientated snacks. An online experiment comprising four between-subjects food image conditions (no image; food photo; food cartoon; cartoon of children gardening) and two within-subjects snack type conditions (fruit; vegetable) was conducted with N = 800 Australian adult parents/guardians of children aged 4-10 years.

The health halo effect of 'low sugar' and related claims on alcoholic drinks: an online experiment with young women.

Aims: To investigate whether 'low sugar' and related claims influence consumers' perceptions of the healthiness or other attributes of alcoholic drinks, promote greater consumption or impact diet and activity behaviour intentions.

Method: N = 501 Australian women aged 18-35 viewed and rated six images of alcoholic drinks in a randomized online experiment with a 2 (claim: low sugar claim, no claim control) × 2 (drink type: cider, ready-to-drink spirits) between-subjects design.

Results: Participants who viewed drinks with low sugar claims rated them as healthier, less harmful to health, lower in sugar and kilojoules, and more suitable for weight management and a healthy diet than participants who viewed identical drinks with no claim (P < 0.

Divergence of the Stark collision operator at large impact parameters in plasma spectroscopy models.

The divergence that occurs at large impact parameters in Stark collision operators is examined for low-density hydrogen plasmas. In a previous work [J. Rosato, H.

Influence of correlated collisions on Stark-broadened lines in plasmas.

An investigation of spectral line broadening in plasmas is carried out within a kinetic-theory approach, based on the Bogoliubov-Born-Green-Kirkwood-Yvon (BBGKY) hierarchy. The model employs a resummation procedure to account for correlated emitter-perturber collisions. Applications to hydrogen lines indicate that such collisions strongly affect the width and the shape in the core region.

Stark broadening of hydrogen lines in low-density magnetized plasmas.

Stark broadening of hydrogen lines in the presence of a magnetic field is revisited, with emphasis on the role of the ion component under typical conditions of magnetized fusion devices. An impact theory for ions valid at low density (N_{e} < or approximately 10;{14} cm;{-3}) and taking into account the Zeeman degeneracy removal of the atomic states is developed. It is shown that the Stark widths of the Lorentz triplet components strongly depend on the magnetic field.
