Group Polarization01:01

Group Polarization

37.9K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Regulation of Expression Occurs at Multiple Steps

24.9K
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

Dynamic Equilibrium

59.8K
A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...

Regulation of Expression at Multiple Steps

1.2K
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

Levels of Communication II: Organizational, Public, and Group Dynamics

2.7K
Effective communication is the foundation of a good organization. Communication is the lifeblood of an organization that connects the group with messages. In an organization, communication occurs in upward, downward, and horizontal lines. Downward communication travels from the administrative and senior levels to the staff through official channels such as manuals, rules and regulations, and organizational charts. Staff members initiate upward communication, which is addressed to executives and...

Area of Science:

  • Social Sciences
  • Computational Social Science
  • Opinion Dynamics

Background:

  • Existing opinion dynamics models often overlook how interactions affect public expression willingness.
  • Individuals' perception of majority or minority status influences their inclination to voice opinions.

Purpose of the Study:

  • To introduce and analyze a novel model of public opinion expression.
  • To investigate the social-structural conditions that lead to public opinion predominance.
  • To identify circumstances where minority opinions can dominate public discourse.

Main Methods:

  • Formulated a multigroup majority game to model opinion expression.
  • Investigated Nash equilibria of the game.
  • Employed Q-learning and a mean-field approach to create a two-dimensional dynamical system.
  • Conducted a comprehensive bifurcation analysis of the system's parameters.

Main Results:

  • The model demonstrates how group perception (majority/minority) impacts opinion expression.
  • Identified specific social-structural conditions conducive to public opinion leadership by different groups.
  • Revealed scenarios where a minority group can achieve public discourse dominance.

Conclusions:

  • The developed model provides insights into the complex interplay between opinion exchange, group perception, and public expression.
  • Understanding these dynamics is crucial for predicting public opinion formation and the influence of minority viewpoints.
  • The findings highlight the importance of social structure in shaping public discourse outcomes.
