Hierarchy of Motor Control01:18

Hierarchy of Motor Control

6.2K
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

Maslow's Need Hierarchy Theory

1.1K
Abraham Maslow's theory of motivation, introduced in 1943, is widely known as the "Hierarchy of Needs." This theory posits that human needs are arranged in a hierarchical structure, starting with basic survival needs and progressing toward more complex psychological and self-fulfillment desires. The hierarchy is typically a pyramid, and the lower needs must be satisfied to reach the next level.
At the pyramid's base are physiological needs, including food, water, and shelter...

Formation of Species01:31

Formation of Species

45.1K
Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

Solution Formation02:16

Solution Formation

37.6K
There is no one solvent that can dissolve every type of solute. Some substances that readily dissolve in a certain solvent might be insoluble in a different solvent. A simple way to predict which substances dissolve in which solvent is the phrase "like dissolves like". This means that polar substances, such as salt and sugar, dissolve in a polar substance like water. In contrast, non-polar substances are more soluble in non-polar solvents such as carbon tetrachloride.
This selective...

Standard Enthalpy of Formation02:37

Standard Enthalpy of Formation

49.2K
Enthalpy changes are typically tabulated for reactions in which both the reactants and products are at the same conditions. A standard state is a commonly accepted set of conditions used as a reference point for the determination of properties under other different conditions. For chemists, the IUPAC standard state refers to materials under a pressure of 1 bar and solutions at 1 M and does not specify a temperature. Many thermochemical tables list values with a standard state of 1 atm. Because...

Formation of Complex Ions03:45

Formation of Complex Ions

26.1K
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

Area of Science:

  • Computational Social Science
  • Network Science
  • Sociology

Background:

  • Wikipedia operates without formal hierarchy, relying on volunteer editors.
  • Understanding coordination in decentralized online communities is crucial.

Purpose of the Study:

  • To investigate how coordination emerges in Wikipedia's decentralized editing environment.
  • To model Wikipedia's editing history as an evolving multiplex network.

Main Methods:

  • Developed a novel method to represent Wikipedia edit histories as multiplex networks.
  • Utilized relational event models for signed networks to analyze edit event sequences.
  • Analyzed a dataset of 12,719 revisions from 7,657 unique users.

Main Results:

  • Identified emergent linear dominance hierarchies regulating production relations.
  • Found evidence that dyadic interactions create systematic extra-dyadic dependencies.
  • Observed structures partially consistent with a hierarchical interpretation of the editing network.

Conclusions:

  • Coordination in Wikipedia is facilitated by an emergent hierarchy driven by self-organizing edit event sequences.
  • The study provides a new framework for analyzing decentralized online collaboration.
  • Findings offer insights into the dynamics of large-scale, volunteer-driven knowledge production.
