text: Water quality and hypoxia in lakes and reservoirs are strongly associated
with water renewal. Yet vertical water exchange is still not fully understood
and challenging to evaluate in highly dynamic systems. Here, we applied a scaling
approach using the vertical timescale, vertical water age (VWA), defined as time
since a water parcel last touched the water surface. We established a 3D hydrodynamic-based
age model to quantify the vertical water renewal in Xiangxi Bay, a tributary bay
of the Three Gorges Dam. The integrated effects of hydrodynamic processes like
stratification, intruding density currents from the mainstream, and upstream inflow
on the vertical renewal were accounted for. Results indicated that the spatial–temporal
distribution of VWA in Xiangxi Bay depended on stratification and forms of intruding
density currents. Age was large in spring and summer, and small in autumn and
winter, reaching a maximum of 25 days in April. The vertical water renewal was
faster during bottom intrusions from the mainstream than during middle and surface
intrusions. At times, the epilimnion contained old water due to circulations,
and the hypolimnion contained young water due to upstream flushing. In contrast
to natural lakes, the bottom water was often younger than overlying intermediate
waters. This demonstrated that mixed layer depth was insufficient to fully capture
the vertical exchange in riverine systems with significant surface/bottom intrusion.
The findings suggested VWA as a quantitative measure of vertical water transport
in highly dynamic systems and its usability for environmental water management.

text: "Background\r\nIndividuals with borderline personality disorder (BPD) frequently
alter between idealizing and devaluing other persons, which has been linked to
an increased tendency to update self-relevant beliefs and impressions. We hypothesized
that increased impression updating could stem from reduced attitude contextualization,
i.e., a process in which impression-disconfirming information is linked to contextual
cues.\r\nMethods\r\nIndividuals diagnosed with BPD and controls (recruited online,
with unknown diagnostic status) completed an impression formation paradigm. They
first learned about the positive or negative behaviors of others in one Context
A (e.g., Person 1 is helpful), followed by learning about behaviors of the opposite
valence in a second Context B (Person 1 is rude). We also manipulated between
participants whether the observed behaviors were directed toward the study participants
(self-relevant) or, more generally, at other people (other-relevant). The contexts
were marked by differently-colored backgrounds (e.g., yellow vs. blue), to avoid
influences of prior knowledge or experiences. After exposure to information in
both contexts, participants rated their impressions of the persons in Context
A, Context B, and, crucially, a previously unknown Context C (white background).
We examined whether the initial or an updated impression (re-)emerged in Context
C.\r\nResults\r\nInitial impressions remained stable and dominated the ratings
of controls across contexts A, B, and C for both self-relevant and other-relevant
behaviors, consistent with contextualizing impression-disconfirming information.
As expected, however, individuals with BPD only showed updated impression ratings
in Context C for self-relevant behaviors, consistent with the assumed reduced
tendency to contextualize impression-disconfirming self-relevant information.
Further exploratory analyses suggest that more severe BPD symptoms predicted more
pronounced impression updating in the self-relevant condition.\r\nConclusions\r\nThe
findings help to illuminate the mechanisms underlying interpersonal problems in
individuals with BPD. People with BPD are not just more inclined to discard positive
first impressions but to re-evaluate disliked others when they behave positively,
contributing to the volatility of interactions with others. Contextualization
has known and modifiable antecedents, and the study may thus provide potential
targets for therapeutic intervention. Future studies will need to replicate the
findings with specified controls."
