Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

15.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Impulse01:13

Impulse

21.4K
According to Newton’s second law of motion, the rate of change of the momentum of an object is the net external force acting on it. The total change in momentum between two timepoints thus depends on both the external force acting on it and the time over which it acts. Describing this mathematically, the total change of an object’s motion is proportional to the force vector and the time over which it is applied. This product is called impulse.
Additionally, it can be shown that the...

Impulse Response01:17

Impulse Response

733
The impulse response is the system's reaction to an input impulse. In an RC circuit, the voltage source is the input, and the capacitor's voltage is the output. The system's state and output response before and after input excitation are distinctly defined.
Kirchhoff's law forms an input signal equation, with the capacitor's current and voltage providing the output. Substituting the current and dividing by RC yields a differential equation. The output for an impulse input is the impulse...

Pilot and Numeric Relaying01:21

Pilot and Numeric Relaying

485
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Role of Affect in Interpersonal Attraction01:24

Role of Affect in Interpersonal Attraction

218
Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

The Influence of Affect on Cognition01:29

The Influence of Affect on Cognition

272
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

Summary

Daily fluctuations in impulsivity, especially when combined with positive affect, may increase alcohol problems in young adults. Understanding within-person changes in impulsivity is key for predicting drinking behaviors.

Area of Science:

  • Psychology
  • Addiction Research
  • Behavioral Science

Background:

  • Limited research explores within-person fluctuations in impulsivity.
  • Previous studies link trait impulsivity to alcohol involvement.
  • The connection between daily impulsivity changes and immediate drinking behaviors is unclear.

Purpose of the Study:

  • To assess within-person variability in daily impulsivity.
  • To examine the impact of daily impulsivity on alcohol use (drinking occurrence, quantity, intentions).
  • To investigate the role of daily affect as a moderator in these relationships.

Main Methods:

  • A pilot study with 24 young adult drinkers.
  • 14-day daily diary methodology.
  • Self-reported daily impulsivity, affect, and alcohol consumption.

Main Results:

  • 42.5% of impulsivity variance was within-person.
  • Daily impulsivity predicted increased heavy episodic drinking and alcohol problems.
  • Positive affect moderated impulsivity's link to alcohol problems and drinking intentions.

Conclusions:

  • Within-person changes in impulsivity and positive affect are potential daily risk factors for alcohol problems.
  • Future research should consider positive affect when studying daily impulsivity and negative outcomes.
