Social Scripts02:10

Social Scripts

9.4K
People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter),...

Social Exchange Theory02:06

Social Exchange Theory

34.5K
We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

Social Traps

22.3K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Signal and System01:26

Signal and System

643
A signal x(t) is a set of data or a time function representing a variable of interest. Signals typically convey information about a phenomenon, such as atmospheric temperature, humidity, human voice, television images, a dog's bark, or birdsongs. More generally, a signal can be a function of more than one independent variable. For instance, images depend on horizontal and vertical positions and can be regarded as two-dimensional signals. However, this text will focus on one-dimensional...

Regulation of Stroke Volume01:27

Regulation of Stroke Volume

3.2K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Area of Science:

  • Public Health
  • Social Media Analysis
  • Digital Communication

Background:

  • Social media platforms like Twitter are increasingly used for health-related discussions.
  • Understanding online health conversations is crucial for public health interventions.
  • Limited research exists on stroke-related discussions on Twitter within the Indian context.

Purpose of the Study:

  • To analyze stroke-related conversations on Twitter in India.
  • To identify key topics, message sources, reach, and influential users.
  • To provide insights for stakeholders on community needs for stroke knowledge, support, and interventions.

Main Methods:

  • Systematic collection of geo-tagged Twitter posts on stroke from India (Nov 2022 - Feb 2023) using the Twitter API.
  • Application of Latent Dirichlet Allocation (LDA) topic modeling to identify recurring themes.
  • Social network analysis to identify influential users and analyze message reach.

Main Results:

  • Approximately 50% of stroke tweets focused on seeking support and sharing post-stroke bereavement, exhibiting the highest reachability.
  • Individual Twitter users authored 40% of the tweets.
  • Topics on risk factors, awareness, and prevention constituted the smallest proportion (14.6%), while management, research, and promotion had the lowest retweet ratio.

Conclusions:

  • Twitter serves as a significant platform for disseminating and acquiring stroke-related information in India.
  • Identified topics and discussion content offer valuable resources for public health professionals.
  • Insights can inform targeted educational and engagement strategies for stroke awareness and support in India.
