Cooperative Allosteric Transitions01:58

Cooperative Allosteric Transitions

8.7K
Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

Cooperative Binding of Transcription Regulators02:13

Cooperative Binding of Transcription Regulators

7.2K
Transcriptional regulators bind to specific cis-regulatory sequences in the DNA to regulate gene transcription. These cis-regulatory sequences are very short, usually less than ten nucleotide pairs in length. The short length means that there is a high probability of the exact same sequence randomly occurring throughout the genome.  Since regulators can also bind to groups of similar sequences, this further increases the chances of random binding. Transcriptional regulators form...

Physiological Foundation of Stress01:24

Physiological Foundation of Stress

617
Stress triggers a coordinated physiological response involving the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis. This dual activation ensures that the body is prepared for both immediate and prolonged stress management. The process begins with the perception of a stressor. This initial phase activates the SNS, leading to the rapid release of adrenaline (epinephrine) from the adrenal glands.

Social Foundations of Self II: The Generalized Other01:20

Social Foundations of Self II: The Generalized Other

245
According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group...

Summary

Social norms, particularly conditional cooperation, causally drive human cooperation. Empirical methods identify these norms, and people prefer institutions that guide cooperation and enforce norms, highlighting the importance of social preferences and punishment constraints.

Area of Science:

  • Social Sciences
  • Behavioral Economics
  • Sociology

Background:

  • Social norms are theorized to shape human cooperation.
  • Empirical identification of specific norms is challenging, limiting their explanatory power.
  • The causal role of social norms in cooperation remains debated.

Purpose of the Study:

  • To empirically identify the norm of conditional cooperation as a driver of human behavior.
  • To demonstrate the causal effects of social norms on cooperation.
  • To investigate the role of social preferences and punishment in norm compliance.

Main Methods:

  • Utilized advanced empirical methods for identifying social norms.
  • Analyzed the relationship between social preferences, norm compliance, and punishment.
  • Examined individual preferences for institutional environments regulating cooperation.

Main Results:

  • The norm of conditional cooperation was empirically identified as a key driver of cooperation.
  • Social norms were shown to have significant causal effects on cooperative behaviors.
  • Willingness to punish free-riders is linked to social preferences, but normative constraints on punishment are crucial for effectiveness.
  • A majority favors institutions that guide cooperation and norm enforcement.

Conclusions:

  • Social norms, specifically conditional cooperation, are powerful causal drivers of human cooperation.
  • Effective norm enforcement requires normative constraints on peer punishment.
  • Individuals prefer structured environments that facilitate cooperative behavior and norm adherence.
