Non-invasive microsensing technique has been widely used in evaluating the adaptive responses of plant cells and tissues to abiotic stresses. One of the representative techniques is the microelectrode ion flux estimation (MIFE), which allows concurrent quantification of net fluxes with high spatial and temporal resolution. More importantly, this technique permits simultaneous recording of ion concentration and mobility with less intervention to the in situ physiological status. With the availability of such advanced technique, the last three decades have seen a significant progress towards the role of ion signaling in a variety of abiotic stresses including salinity, extreme temperature, osmotic stress, hypoxia, and drought...

BACKGROUND: Fluent word reading is a key characteristic of skilled reading, yet most children with reading disorders have impaired word-reading skills. Previous research has demonstrated that multi-component interventions targeting phonemic awareness and the alphabetic principle are effective for children with reading disorders. However, about 25% of children fail to respond to these interventions. While it has been difficult to isolate the active ingredient, the findings of some studies suggest that tasks targeting phonological recoding and orthographic processing are essential elements in improving decoding...

Children demonstrate a pervasive in-group bias, preferring their in-group across a range of contexts that encompass measures of liking, imitation, and, in some cases, resource allocation. A growing number of studies have begun to explore whether antisocial in-group behavior reduces the robustness of this bias. However, these studies have focused on transgression evaluations, with only two studies focusing on social learning and none explicitly on imitation. This, therefore, limits the extent to which children's responses to interaction between in-group bias and antisocial behavior can be fully understood...
