In- and Out-Groups01:31

In- and Out-Groups

43.9K
People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

Group Design

10.9K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Impact of Groups on Groups

289
Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

Leaving Groups02:14

Leaving Groups

9.9K
The nature of leaving groups strongly influences the outcome of a nucleophilic substitution reaction.
In general, in a nucleophilic substitution reaction, a nucleophile displaces a functional group, called the leaving group, from the substrate to give a substituted product. A leaving group departs the substrate molecule through heterolytic cleavage, taking the pair of electrons with it to become a relatively stable weak base in the form of an anion or a neutral molecule.

Impact of Groups on Individuals

422
Groups play a fundamental role in shaping individual behavior, as they establish norms that guide interactions and decision-making. Social psychology examines how individuals conform to group expectations, often adjusting their attitudes and actions to align with group norms. These norms can be formal, such as workplace policies, or informal, such as unspoken social expectations within a fraternity.Conformity and Social InfluenceConformity arises when individuals modify their behaviors or...

Groupthink

50.2K
When in group settings, we are often influenced by the thoughts, feelings, and behaviors around us. Groupthink is another phenomenon of conformity where modification of the opinions of members in a group aligns with what they believe is the group consensus (Janis, 1972). In such situations, the group often takes action that individuals would not perform outside the group setting because groups make more extreme decisions than individuals do. Moreover, groupthink can hinder opposing trains of...

Área de la Ciencia:

  • Cristalografía
  • Teoría de grupos
  • Química computacional

Sus antecedentes:

  • Las estructuras cristalinas se definen típicamente mediante matrices aumentadas que representan transformaciones afines.
  • Una descripción alternativa utiliza presentaciones de grupos con generadores y relaciones definitorias.
  • Los grafos de Cayley visualizan los elementos del grupo y las acciones del generador, conectando la teoría de grupos con las representaciones geométricas.

Objetivo del estudio:

  • Explorar la relación entre las presentaciones de grupos y los grafos de Cayley para describir la simetría cristalina.
  • Demostrar cómo la interacción entre estas herramientas matemáticas puede generar nuevas perspectivas sobre las estructuras cristalinas.

Principales métodos:

  • Utilización de presentaciones de grupos para definir las operaciones de simetría de una estructura cristalina.
  • Construcción del grafo de Cayley correspondiente a la presentación del grupo.
  • Análisis de las propiedades combinatorias y geométricas derivadas del grafo de Cayley y la presentación del grupo.

Principales resultados:

  • El estudio demuestra que la combinación de grafos de Cayley con presentaciones de grupos proporciona un método potente para analizar la simetría cristalina.
  • Se puede extraer información combinatoria y geométrica específica sobre las estructuras cristalinas de este enfoque integrado.

Conclusiones:

  • La interacción entre los grafos de Cayley y las presentaciones de grupos ofrece una perspectiva novedosa para comprender la simetría cristalina.
  • Este enfoque mejora la derivación de información estructural y de simetría en comparación con los métodos matriciales tradicionales.
