Social Exchange Theory02:06

Social Exchange Theory

34.5K
We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

Capillary Exchange

The cardiovascular system's chief role is to disseminate gases, nutrients, waste, and other substances to the body's cells. Small molecules like gases, lipids, and lipid-soluble substances directly diffuse through capillary wall endothelial cell membranes. Glucose, amino acids, and ions, including sodium, potassium, calcium, and chloride, use transporters for facilitated diffusion via membrane-specific channels. Glucose, ions, and bigger molecules may also pass through intercellular...

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.

Data: Types and Distribution01:19

Data: Types and Distribution

722
In biostatistics, data are the observations collected for analysis. There are two main types: parametric and non-parametric. Parametric data, which include continuous (e.g., weight) and discrete numerical data (e.g., number of tablets), assume a particular distribution pattern, often the normal distribution. Non-parametric data do not adhere to a specific distribution and typically comprise nominal (e.g., gender) and ordinal categorical data (e.g., pain scale ratings).

Relation Between the Distributed Load and Shear01:23

Relation Between the Distributed Load and Shear

633
Understanding the relationship between the distributed load and shear force in structural analysis is crucial for analyzing beams subjected to various loading conditions. Consider the case of a beam experiencing a distributed load, two concentrated loads, and a couple moment.

Area of Science:

  • Computer Science
  • Information Systems
  • Blockchain Technology

Background:

  • Data is a valuable digital asset in modern economies, traded on peer-to-peer (P2P) marketplaces.
  • Traditional centralized data marketplaces lack trust, transparency, fairness, accountability, and security.
  • Users often lack control and consent over their personal data in existing platforms.

Purpose of the Study:

  • To propose and evaluate DataMesh+, a decentralized P2P data exchange model for self-sovereign data marketplaces.
  • To address the limitations of centralized data trading platforms by leveraging blockchain technology.
  • To empower users with full sovereignty and control over their data.

Main Methods:

  • Design and implementation of a blockchain-powered decentralized P2P data exchange model (DataMesh+).
  • Leveraging blockchain-based smart contracts for enabling secure and transparent data trading.
  • Experimental testing and validation to evaluate model acceptability and reliability.
  • Assessment of security and performance, including smart contract costs and network performance.

Main Results:

  • Demonstrated the feasibility of the DataMesh+ model through design and implementation.
  • Experimental validation confirmed the model's acceptability and reliability for data exchange.
  • Security and performance assessments provided insights into transaction costs and network efficiency.

Conclusions:

  • DataMesh+ offers a viable, user-centric decentralized solution for data marketplaces.
  • The blockchain-powered approach enhances trust, transparency, fairness, and security in data trading.
  • Users gain full sovereignty and control over their data within the proposed marketplace model.
