Characteristics of Life Events During Adolescence l

Two studies o f the characteristics o f life events during adolescence are reported. In the first, open-ended reports o f major life events and daily events were obtained from early, middle, and late adolescents. Analyses o f the frequency o f past events perceived as positive versus negative revealed effects for type of event (major vs. daily), age, and gender. In contrast, anticipated events ...

Uncovering Spatiotemporal Characteristics of Human Online Behaviors during Extreme Events

In response to an extreme event, individuals on social media demonstrate interesting behaviors depending on their backgrounds. By making use of the large-scale datasets of posts and search queries collected from Twitter and GoogleTrends, we first identify the distinct categories of human collective online concerns and durations based on the distributions of solo tweets and new incremental tweet...

Characteristics of U.S. Extreme Rain Events during 1999–2003

This study examines the characteristics of a large number of extreme rain events over the eastern two-thirds of the United States. Over a 5-yr period, 184 events are identified where the 24-h precipitation total at one or more stations exceeds the 50-yr recurrence amount for that location. Over the entire region of study, these events are most common in July. In the northern United States, extr...

Spatio-Temporal Variation of Suspended Sediment Concentration at Downstream of a Sand Mine

The growing population led to greater human need to use natural resources such as sand and gravel mines. Direct removal of sands from the bed river leads to increase suspended sediment concentrations in downstream of harvested area and creates other problems viz. filling reservoirs, change in hydraulic characteristics of the channel and environmental damages. However, the range of temporal and ...
