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.
Impact of Schemas01:30

Impact of Schemas

Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...

Schemata

A schema is a mental construct that organizes related concepts, allowing the brain to process information efficiently. Upon activation, schemata facilitate assumptions about people or objects.
Two types of schemata are:

Self-Schemas

In general, 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.
Anatomical Terminology01:20

Anatomical Terminology

Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Area of Science:

  • Biomedical Informatics
  • Data Management
  • Scientific Research

Background:

  • Scientific data management requires robust metadata standards.
  • Existing systems often lack interoperability for data exchange.
  • The Biomedical Informatics Research Network (BIRN) developed a solution.

Purpose of the Study:

  • To introduce the XCEDE (XML-based Clinical and Experimental Data Exchange) XML schema.
  • To detail its function as a specification for scientific data exchange.
  • To highlight its extensibility and data provenance capabilities.

Main Methods:

  • Development of an extensive metadata hierarchy using XML.
  • Implementation of data provenance tracking at each hierarchy level.
  • Designing the schema for extensibility to accommodate diverse data modalities.

Main Results:

  • XCEDE schema (version 2.0) provides a structured metadata hierarchy for experiments.
  • Enables traceable records of data processing and changes.
  • Facilitates data exchange between databases, analysis tools, and web services.

Conclusions:

  • XCEDE offers a standardized, extensible framework for scientific data exchange.
  • It enhances data integrity through provenance tracking.
  • Promotes interoperability in biomedical research data management.
