The family is an important social context where children learn and adopt eating behaviors. Specifically, parents play the role of health promoters, role models, and educators in the lives of ...children, influencing their food cognitions and choices. This study attempts to systematically review empirical studies examining the influence of parents on child food consumption behavior in two contexts: one promotive in nature (e.g., healthy food), and the other preventive in nature (e.g., unhealthy food).
From a total of 6,448 titles extracted from Web of Science, ERIC, PsycINFO and PubMED, seventy eight studies met the inclusion criteria for a systematic review, while thirty seven articles contained requisite statistical information for meta-analysis. The parental variables extracted include active guidance/education, restrictive guidance/rule-making, availability, accessibility, modeling, pressure to eat, rewarding food consumption, rewarding with verbal praise, and using food as reward. The food consumption behaviors examined include fruits and vegetables consumption, sugar-sweetened beverages, and snack consumption.
Results indicate that availability (Healthy: r = .24, p < .001; Unhealthy: r = .34, p < .001) and parental modeling effects (Healthy: r = .32, p < .001; Unhealthy: r = .35, p < .001) show the strongest associations with both healthy and unhealthy food consumption. In addition, the efficacy of some parenting practices might be dependent on the food consumption context and the age of the child. For healthy foods, active guidance/education might be more effective (r = .15, p < .001). For unhealthy foods, restrictive guidance/rule-making might be more effective (r = -.11, p < .01). For children 7 and older, restrictive guidance/rule-making could be more effective in preventing unhealthy eating (r = - .20, p < .05). For children 6 and younger, rewarding with verbal praise can be more effective in promoting healthy eating (r = .26, p < .001) and in preventing unhealthy eating (r = - .08, p < .01).
This study illustrates that a number of parental behaviors are strong correlates of child food consumption behavior. More importantly, this study highlights 3 main areas in parental influence of child food consumption that are understudied: (1) active guidance/education, (2) psychosocial mediators, and (3) moderating influence of general parenting styles.
Cyberbullying has become a critical social issue, which severely threatens children and adolescents’ physical and psychological health. The current research systematically examined the predictors of ...cyberbullying from the social cognitive and media effects approach. Specifically, this study identified 16 predictors of cyberbullying perpetration and victimization and examined the magnitude of the effects of these predictors by meta-analyzing 81 empirical studies, which represented a total sample of 99,741 participants and yielded 259 independent correlations. The results revealed that risky information and communications technology (ICT) use, moral disengagement, depression, social norms, and traditional bullying perpetration were the main predictors of cyberbullying perpetration, while risky ICT use and traditional bullying victimization were the major contributors of cyberbullying victimization. According to the moderator analyses, country of the sample, sampling method, age, and media platform were significant moderators of the relationships between some specific predictors and cyberbullying perpetration and victimization. Implications for future cyberbullying research were discussed.
Abstract
General relativistic effects have long been predicted to subtly influence the observed large-scale structure of the universe. The current generation of galaxy redshift surveys has reached a ...size where detection of such effects is becoming feasible. In this paper, we report the first detection of the redshift asymmetry from the cross-correlation function of two galaxy populations that is consistent with relativistic effects. The data set is taken from the Sloan Digital Sky Survey Data Release 12 CMASS galaxy sample, and we detect the asymmetry at the 2.7σ level by applying a shell-averaged estimator to the cross-correlation function. Our measurement dominates at scales around 10 h
−1 Mpc, larger than those over which the gravitational redshift profile has been recently measured in galaxy clusters, but smaller than scales for which linear perturbation theory is likely to be accurate. The detection significance varies by 0.5σ with the details of our measurement and tests for systematic effects. We have also devised two null tests to check for various survey systematics and show that both results are consistent with the null hypothesis. We measure the dipole moment of the cross-correlation function, and from this the asymmetry is also detected, at the 2.8σ level. The amplitude and scale dependence of the clustering asymmetries are approximately consistent with the expectations of general relativity and a biased galaxy population, within large uncertainties. We explore theoretical predictions using numerical simulations in a companion paper.
Prior studies have investigated the antecedents of Health Information Seeking (HIS) using different theoretical frameworks, whereas the inconsistencies in the reported findings warrant a more ...comprehensive synthesis of this body of knowledge. This meta-analysis identified 12 major antecedents of HIS from six widely used information seeking models examining HIS, developed an organizing framework that segmented current antecedents into cognitive, affective, sociocultural, and information carrier categories, and compared their associations with HIS by meta-analyzing 89 empirical studies (N = 62,957). Results showed that seeking-related subjective norms and information utility yielded the strongest associations with HIS, whereas cognitive and affective factors demonstrated weaker associations with HIS. Illness types, information-seeking channels, and sampling methods significantly moderated the associations between some predictors and HIS. Implications and directions for future research were discussed.
Matter evolved under the influence of gravity from minuscule density fluctuations. Nonperturbative structure formed hierarchically over all scales and developed non-Gaussian features in the Universe, ...known as the cosmic web. To fully understand the structure formation of the Universe is one of the holy grails of modern astrophysics. Astrophysicists survey large volumes of the Universe and use a large ensemble of computer simulations to compare with the observed data to extract the full information of our own Universe. However, to evolve billions of particles over billions of years, even with the simplest physics, is a daunting task. We build a deep neural network, the Deep Density Displacement Model (D³M), which learns from a set of prerun numerical simulations, to predict the nonlinear large-scale structure of the Universe with the Zel’dovich Approximation (ZA), an analytical approximation based on perturbation theory, as the input. Our extensive analysis demonstrates that D³M outperforms the second-order perturbation theory (2LPT), the commonly used fast-approximate simulation method, in predicting cosmic structure in the nonlinear regime. We also show that D³M is able to accurately extrapolate far beyond its training data and predict structure formation for significantly different cosmological parameters. Our study proves that deep learning is a practical and accurate alternative to approximate 3D simulations of the gravitational structure formation of the Universe.
Despite the recent approval of cultured meat products in Singapore, the understanding of public perceptions towards this novel food technology remains limited. Utilizing attitude formation theory and ...the mental models approach, this study compares the mental models of the general public and experts regarding their risk and benefit perceptions of cultured meat. Through four online focus group discussions with 40 participants, we found convergences in the mental models of experts and the general public concerning perceived individual- and societal-level benefits of cultured meat (e.g., health benefits and food security) as well as their perceived individual-level risks of cultured meat (e.g., potential health issues and affordability). However, divergences in understanding societal-level risks were noted; the public expressed concerns about the challenges of cultured meat to religious and racial dietary customs, while experts highlighted potential investment uncertainties due to unclear consumer acceptance of cultured meat. Theoretical and practical implications are discussed.

Contact-tracing applications (CTAs) have been introduced as part of the COVID-19 containment strategy worldwide. In most countries, however, their uptake has been too low to realize their full ...potential. This study contributes to the understanding of CTA adoption by investigating the influence of public perceptions on adoption and the role of media in forming these perceptions in Singapore and Switzerland. In a comparative approach, online surveys in both countries (Singapore: N = 998; Switzerland: N = 1,022) and multigroup structural equation modeling reveal national differences. First, attention to media was associated more strongly with app-related perceptions in Singapore than in Switzerland, with news media attention correlating positively with favorable perceptions in both countries (i.e., perceived usefulness of the CTA, perceived social norms of adoption) and social media attention correlating negatively with these perceptions in Singapore. Second, regarding the influence of these perceptions on CTA adoption, perceived usefulness was associated with CTA adoption in Switzerland but not in Singapore; conversely, perceived social norms were more important in Singapore than in Switzerland. These results suggest that the communicative formation of public perceptions and their behavioral relevance are contingent on media systems (authoritarian vs. democratic media system) and cultural values (collectivism vs. individualism), highlighting the theoretical value of a country-comparative approach and the practical need for a culturally sensitive implementation of health technologies.
Abstract
This study answers two research questions regarding framing theory. First, what happens when frames are challenged? Second, how resistant are the opinions that initial frames induce? 1,006 ...participants completed an online experiment where they were randomly assigned to first view a blog post with either complementary or competitive framing on driverless cars. Participants also viewed a blog post that challenged the stance of the first blog post. Results revealed that complementary frames polarized opinions, while competitive frames neutralized framing effects. Competitive frames induced more resistant opinions than complementary frames did. Attitude and support were susceptible to new, antagonistic information. This study concludes that framing effects are ephemeral and easily challenged by different information.
This study investigates the flow of energy-related information, which plays a vital role in promoting the public understanding and support for various energy sources. Through 12 focus group ...discussions with the public and energy experts, this study found that energy information flows from scientists to the public through both direct (e.g., roadshows, scientists’ blogs) and indirect (via agents, e.g., school, news media) channels. However, communication gaps remain between scientists and the public. First, the public commonly obtains information from personal experience and the media but not directly from scientists. Second, while the public stressed the importance of mass media and social media, only a few experts reported writing news commentaries or making social media posts about energy. Third, while scientists emphasize their relationships with the government and other agencies in disseminating information, the public shows relatively weak trust in these agencies. Implications are made for future research and public communication on energy issues.

Scientists play important roles in conducting public engagement, but evidence shows that scientists perceive great challenges in doing so. Drawing broadly from the theory of planned behavior (TPB), ...this study examines factors predicting scientists’ willingness to conduct public engagement. This study further examines how perceived behavioral control (PBC) of conducting public engagement would moderate the relationships between the proposed predictors and scientists’ willingness to conduct public engagement. Using survey data collected from 706 scientists based in Singapore, this study found that attitude toward and personal norms of conducting public engagement, as well as PBC, significantly predicted scientists’ willingness to conduct public engagement. Notably, PBC interacted with attitude toward conducting public engagement, the perceived descriptive norms, the perceived positive media influence, and the perceived negative external norms of conducting public engagement, as well as personal norms of conducting public engagement to predict scientists’ willingness to conduct public engagement. We postulated the key role that the perception of the ease or difficulty plays in motivating scientists to conduct the skill-intensive endeavor explains the significant moderating effects. The theoretical implications on the TPB and the practical implications for public engagement are further discussed.
