Citation network analysis of organic LEDs

The field of organic light-emitting diodes (OLEDs) is an emergent research domain because of both scientific interest in chemistry and condensed matter physics and industrial importance as flat panel displays. In this paper, we analyzed a citation network of OLED papers and used a topological clustering method to investigate the structure of research and to detect emerging research domains. We found that most papers belong to two main clusters: organics and polymers. These two clusters have distinctive differences in subcluster structures and journals where papers are published. Supposing this discrepancy to indicate research progress, organics are in the applied research stage, while polymers are in the basic research stage.     

Do depicted suggestions of portion size on‐pack impact how much (un)healthy food children consume

In previous decades, portion and pack sizes of many foods tended to increase while, more recently, some foods started to downsize. These changes in actual portion sizes typically get coverage but less attention is given to the suggested portion sizes for multi‐serving food packages, and to what the impact is of the depicted portion sizes on‐pack. Using two studies with a mixed experimental design among young children, this paper examines the effects of depicted suggestions of portion size manipulation (regular vs. large—‘large’ corresponds to how brands typically depict portions). Both studies used a 2 × 2 × 2 crossover design, with the suggested portion size and food type as within‐ and order as between‐subjects manipulation. In Study 1, we used snacks (grapes and chocolate nuts). In Study 2, we compared two bread spreads (chocolate and cheese). In both the studies, we found that children ate more when presented with the larger depiction of the suggested portion size compared to the regular one. In Study 1, however, we found that children consumed more calories from the chocolate nut than the grape snack, while children did eat more grams of this healthier grape snack. We also showed that consumption in grams only differed between portion sizes when given grapes, which might be due to a possible ceiling effect of chocolate nut consumption. In Study 2, we also found a main effect for spread type as children ate more of chocolate compared to cheese spread. Our results indicate that this subtle on‐pack cue is persuasive. Moreover, policy makers and also marketers could use these insights to stimulate healthy eating in children.

Front-Country Campers' Constraints,Negotiation, and Pro-Environment Behavioral Intention: An Extension to the Theory of Planned Behavior

The theory of planned behavior (TPB) has been successfully tested in leisure and outdoor recreation studies over the last few decades. However, the inclusion of new predictors to improve the theory's predictive power has been encouraged. Utilizing leisure constraints approach, we extended the TPB by adding constraints to the theory. The literature also suggested that individuals employ cognitive and behavioural negotiation strategies to overcome their constraints. Therefore, the influence of negotiation through the constraints was also explored in this study. A sample of 1,009 front-country campers was analyzed to test the proposed extension to the TPB. Results of structural equation modeling confirmed a strong, negative indirect association between constraints and intention. Negotiation was positively and indirectly associated with intention. The proposed extension to the TPB was capable of capturing 84% of variation in intention. Theoretical and practical implications of these findings are discussed.
