[1] DC electric fields and associated E × B plasma drifts detected with the double-probe experiment on the C/NOFS satellite during extreme solar minimum conditions near the June 2008 solstice are shown to be highly variable, with weak to moderate ambient amplitudes of ∼1-2 mV/m (∼25-50 m/s). Average field or drift patterns show similarities to those reported for more active solar conditions, i.e., eastward and outward during day and westward and inward at night. However, these patterns vary significantly with longitude and are not always present. Daytime vertical drifts near the magnetic equator are largest in the prenoon sector. Observations of weak to nonexistent prereversal enhancements in the vertical drifts near sunset are attributable to reduced dynamo activity during solar minimum as well as seasonal effects. Enhanced meridional drifts are observed near sunrise in certain longitude regions, precisely where the enhanced eastward flow that persisted from earlier local times terminates. The nightside ionosphere is characterized by larger-amplitude, structured electric fields dominated by horizontal scales of 500-1500 km even where local plasma densities appear relatively undisturbed. Data acquired during successive orbits indicate that plasma drifts and densities are persistently organized by longitude. The high duty cycle of the C/NOFS observations and its unique orbit promise to expose new physics of the low-latitude ionosphere.
Negative utterances and words have been found to be stronger than positive utterances and words, but what happens if positive and negative utterances are intensified? Two online experiments were carried out in which participants judged the strength of (un)intensified positive and negative evaluations in written dialogues. Both studies showed intensified language was perceived as stronger than unmarked language (i.e., language that was not intensified), and negative evaluations were stronger than positive evaluations. What is more, intensification and polarity interact; the increment of perceived strength for intensified positive adjectives (Study 1) and purely intensified adverbs (
really, very
; Study 2) was bigger than the increment in perceived strength of intensified negative adjective and adverbs. When a meaningful intensifier (
deliciously, disgustingly
) was used, the negativity effect remained. The findings were discussed within cognitive frameworks such as relevance theory, theory of mind, and theory on verbal aggression.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
