Summary
The Green Dot bystander intervention significantly reduced dating and sexual violence acceptance among high school students. This large-scale randomized controlled trial demonstrated effectiveness at both school and individual levels over four years.
Area of Science:
- Public Health
- Social Psychology
- Violence Prevention
Background:
- Bystander-based violence prevention interventions show promise at the individual level.
- Large-scale, longitudinal evaluations at the high school level are lacking.
- This study addresses the gap in understanding school-level effects over time.
Purpose of the Study:
- To evaluate the effectiveness of the 'Green Dot' bystander intervention.
- To assess intervention impact on dating violence and sexual violence acceptance.
- To examine outcomes at both school and individual levels over time.
Main Methods:
- A cluster-randomized controlled trial involving Kentucky high schools (2010-2014).
- Intervention schools received school-wide 'Green Dot' presentations and bystander training.
- 73,044 students completed anonymous surveys assessing violence acceptance.
Main Results:
- Significant reductions in dating violence acceptance observed in intervention schools over time (p < 0.001).
- Significant reductions in sexual violence acceptance observed in intervention schools over time (p < 0.001).
- Reductions were confirmed at the individual level, particularly in years 3 and 4, for both males and females.
Conclusions:
- The 'Green Dot' bystander intervention is effective in reducing dating and sexual violence acceptance.
- The intervention demonstrates efficacy at both the school and individual levels.
- Findings support the implementation of 'Green Dot' as a violence prevention strategy in high schools.

10.2K
The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

01:17Hypothesis: Accept or Fail to Reject?
29.4K
The outcome of any hypothesis testing leads to rejecting or not rejecting the null hypothesis. This decision is taken based on the analysis of the data, an appropriate test statistic, an appropriate confidence level, the critical values, and P-values. However, when the evidence suggests that the null hypothesis cannot be rejected, is it right to say, 'Accept' the null hypothesis?
There are two ways to indicate that the null hypothesis is not rejected. 'Accept' the null...

01:18Reducing Line Loss
372
In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

01:57Adaptations that Reduce Water Loss
28.0K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

02:19Buffer Effectiveness
55.0K
Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised.
The buffer capacity is the amount of acid or base that can be added to a given volume...
