Physical activity and sedentary behaviour trajectories in middle childhood, and the association of these with adiposity.
Background: The prevalence of overweight/obesity increases substantially throughout the middle childhood years. The contribution of physical activity and sedentary behaviour to the development of overweight/obesity is unclear. It is also unknown whether the impacts of physical activity and sedentary behaviour on weight differ by sex.
Purpose: To assess changes in physical activity and sedentary behaviour between the ages of 5-6 and 8-9 years, and the association of these changes with adiposity.
Methods: Longitudinal investigation using an ethnically diverse sample of 1467 children. Separate multilevel linear regression models were constructed with the change in each physical activity/sedentary behaviour measure as the explanatory and follow-up adiposity as the outcome variable.
Results: Physical activity decreased throughout the study period, whilst sedentary time increased. A decrease in moderate-vigorous physical activity (MVPA) was associated with an increase in all adiposity measures in the overall sample and in girls. An increase in TV viewing time was associated with an increase in BMI z-score in the overall sample.
Conclusion: Preventing the decline in MVPA and the increase in TV viewing time during middle childhood could reduce the incidence of overweight/obesity in this age group
The secret languages of coevolved symbioses: Insights from the Euprymna scolopes–Vibrio fischeri symbiosis
Initial Symbiont Contact Orchestrates Host-Organ-wide Transcriptional Changes that Prime Tissue Colonization
SummaryUpon transit to colonization sites, bacteria often experience critical priming that prepares them for subsequent, specific interactions with the host; however, the underlying mechanisms are poorly described. During initiation of the symbiosis between the bacterium Vibrio fischeri and its squid host, which can be observed directly and in real time, approximately five V. fischeri cells aggregate along the mucociliary membranes of a superficial epithelium prior to entering host tissues. Here, we show that these few early host-associated symbionts specifically induce robust changes in host gene expression that are critical to subsequent colonization steps. This exquisitely sensitive response to the host’s specific symbiotic partner includes the upregulation of a host endochitinase, whose activity hydrolyzes polymeric chitin in the mucus into chitobiose, thereby priming the symbiont and also producing a chemoattractant gradient that promotes V. fischeri migration into host tissues. Thus, the host responds transcriptionally upon initial symbiont contact, which facilitates subsequent colonization
Situational factors shape moral judgments in the trolley dilemma in Eastern, Southern, and Western countries in a culturally diverse sample

The Version of Record is available online at: http://dx.doi.org/[insert DOI]The study of moral judgements often centers on moral dilemmas in which options consistent with deontological perspectives (i.e., emphasizing rules, individual rights, and duties) are in conflict with options consistent with utilitarian judgements (i.e., following the greater good based on consequences). Greene et al. (2009) showed that psychological and situational factors (e.g., the intent of the agent or the presence of physical contact between the agent and the victim) can play an important role in moral dilemma judgements (e.g., trolley problem). Our knowledge is limited concerning both the universality of these effects outside the United States and the impact of culture on the situational and psychological factors of moral judgements. Thus, we empirically tested the universality of the effects of intent and personal force on moral dilemma judgements by replicating the experiments of Greene et al. in 45 countries from all inhabited continents. We found that personal force and its interaction with intention, exert influence on moral judgements in the US and Western cultural clusters, replicating and expanding the original findings. Moreover, the personal force effect was present in all cultural clusters, suggesting it is culturally universal. The evidence for the cultural universality of the interaction effect was inconclusive in the Eastern and Southern cultural clusters (depending on exclusion criteria). We found no strong association between collectivism/individualism and moral dilemma judgements
Situational factors shape moral judgments in the trolley dilemma in Eastern, Southern, and Western countries in a culturally diverse sample
Much research on moral judgment is centered on moral dilemmas in which deontological perspectives (i.e., emphasizing rules, individual rights and duties) are in conflict with utilitarian judgements (i.e., following the greater good defined through consequences). A central finding of this field Greene et al. showed that psychological and situational factors (e.g., the intent of the agent, or physical contact between the agent and the victim) play an important role in people’s use of deontological versus utilitarian considerations when making moral decisions. As their study was conducted with US samples, our knowledge is limited concerning the universality of this effect, in general, and the impact of culture on the situational and psychological factors of moral judgments, in particular. Here, we empirically test the universality of deontological and utilitarian judgments by replicating Greene et al.’s experiments on a large (N = X,XXX) and diverse (WEIRD and non-WEIRD) sample across the world to explore the influence of culture on moral judgment. The relevance of this exploration to a broad range of policy-making problems is discussed
