Radical Reactivity: Nucleophilic Radicals01:16

Radical Reactivity: Nucleophilic Radicals

2.7K
Radicals adjacent to electron-donating groups are called nucleophilic radicals. These radicals readily react with electrophilic alkenes. The SOMO–LUMO interactions are the driving force for the reaction, where the high-energy SOMO of the electron-rich, nucleophilic radicals interacts with the low-energy LUMO of the electron-deficient, electrophilic alkenes. Such SOMO–LUMO interactions are the basis of reactive radical traps, affecting the selectivity in radical reactions. For...

Radical Reactivity: Concentration Effects

1.9K
In a radical reaction, the concentration of starting materials governs the selectivity of a radical. For example, the reaction between an alkyl halide and an alkene, in the presence of tin hydride and AIBN, begins with the generation of a tin radical. The generated radical then abstracts halogen from the alkyl halide, producing an alkyl radical. This alkyl radical can either react with tin hydride, yielding an alkane, or add to an alkene, generating a nitrile-stabilized radical, eventually...

The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.

Bystander Effect

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.

Robbers Cave

14.9K
During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Radical Reactivity: Steric Effects01:10

Radical Reactivity: Steric Effects

2.6K
The presence of electron-donating, electron-withdrawing, or conjugating groups adjacent to a radical center, imparts electronic stabilization to the radicals. Examples of such electronically-stabilized radicals are triphenylmethyl, tetramethylpiperidine‐N‐oxide, and 2,2‐diphenyl‐1‐picrylhydrazyl. These radicals are remarkably stable and are known as persistent radicals. Some of the persistent radicals can even be isolated and purified.
Along with electronic...

Summary

Lone-actor terrorists targeting public officials show few behavioral differences from those attacking the general public. This study analyzed 111 cases, finding minimal distinctions in attack capability or operational security between these groups.

Area of Science:

  • Criminology
  • Terrorism Studies
  • Behavioral Psychology

Background:

  • Lone-actor terrorist attacks, particularly against public officials, are a growing concern.
  • Low-tech, difficult-to-detect attacks may increase risks for public officials.
  • Understanding the behavioral differences between lone actors targeting high-value versus general targets is crucial for security.

Purpose of the Study:

  • To investigate if distinct behavioral traits differentiate lone-actor terrorists who target high-value individuals (including public officials) from those targeting the general public.
  • To test hypotheses concerning attack capability and operational security in lone-actor terrorism.

Main Methods:

  • Analysis of a unique dataset comprising 111 lone-actor terrorists.
  • Comparative study examining behavioral traits, attack capability, and operational security.
  • Hypothesis testing to identify differentiating factors between target groups.

Main Results:

  • The study found minimal significant differences between lone-actor terrorists who targeted high-value individuals and those who targeted members of the public.
  • No substantial variations were identified in attack capability or operational security based on the target type.

Conclusions:

  • The lack of differentiation suggests that lone-actor terrorists may not inherently distinguish between high-value and general targets in their planning or execution.
  • Further research is needed to explore theoretical explanations for this homogeneity in behavior.
  • Implications for counter-terrorism strategies may require broader approaches rather than targeting specific behavioral profiles.
