Constraints and Statical Determinacy01:26

Constraints and Statical Determinacy

In structural engineering, the equilibrium of a system is not only determined by its equations of equilibrium but also with the help of constraints. Constraints refer to restrictions on the motion of a system. The proper combinations of constraints can minimize the total number of constraints needed to maintain a system in mechanical equilibrium. When this happens, the system is said to be statically determinate. For such systems, the unknown reaction supports can be estimated using equilibrium...
Woodward–Hoffmann Selection Rules and Microscopic Reversibility01:34

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...
Schemas01:42

Schemas

A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.
The Aufbau Principle and Hund's Rule03:02

The Aufbau Principle and Hund's Rule

To determine the electron configuration for any particular atom, we can build the structures in the order of atomic numbers. Beginning with hydrogen, and continuing across the periods of the periodic table, we add one proton at a time to the nucleus and one electron to the proper subshell until we have described the electron configurations of all the elements. This procedure is called the aufbau principle, from the German word aufbau (“to build up”). Each added electron occupies the subshell of...
Propagation of Uncertainty from Systematic Error01:10

Propagation of Uncertainty from Systematic Error

The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this particular...
Propagation of Uncertainty from Random Error00:59

Propagation of Uncertainty from Random Error

An experiment often consists of more than a single step. In this case, measurements at each step give rise to uncertainty. Because the measurements occur in successive steps, the uncertainty in one step necessarily contributes to that in the subsequent step. As we perform statistical analysis on these types of experiments, we must learn to account for the propagation of uncertainty from one step to the next. The propagation of uncertainty depends on the type of arithmetic operation performed on...

Summary

This study questions the traditional view of linguistic parameters. It suggests language variation may be an externalized trait, emphasizing the role of learning over innate structures.

Area of Science:

  • Linguistics
  • Language Acquisition
  • Computational Linguistics

Background:

  • The classical notion of parameters in linguistic theory is foundational.
  • Parametric hierarchies are a key concept in understanding language variation.
  • Previous models often assume innate, pre-wired parameter values for language acquisition.

Purpose of the Study:

  • To investigate the feasibility of the classical notion of parameters in linguistic theory.
  • To empirically analyze issues related to parametric hierarchies using a novel computational approach.
  • To challenge traditional models of language acquisition and Universal Grammar.

Main Methods:

  • Developed a novel program-based analysis.
  • Utilized an enriched database of 23 contemporary and 5 ancient languages.
  • Conducted empirical analysis of parametric hierarchies.

Main Results:

  • Uncovered empirical problems with classical parametric models.
  • Identified issues with the conceptualization of an overspecified Universal Grammar.
  • Data challenges the idea of innate parameter triggering in language acquisition.

Conclusions:

  • The (bio)logical problem of language acquisition is not solely about triggering innate parameter values.
  • Language variation, termed 'epigenetic' or 'parametric', may be an epiphenomenon of externalization.
  • The learning component in language acquisition might be more significant than previously assumed.
