Compacting Factor test01:22

Compacting Factor test

The compacting factor test is a method used to assess the workability of concrete. It is  especially suitable for concrete mixes containing aggregates up to one and a half inches in size. This test involves specialized equipment consisting of two truncated cone-shaped hoppers and a cylinder, all with polished interior surfaces to minimize friction.
The procedure begins by placing concrete into the upper hopper without any compaction. Once filled, the bottom door of this hopper is opened,...
Factors Affecting Activity Coefficient01:17

Factors Affecting Activity Coefficient

The extended Debye-Hückel equation indicates that the activity coefficient of an ion in an aqueous solution at 25°C depends on three partially interdependent properties: the ionic strength of the solution, the charge of the ion, and the ion size. 
The activity coefficient value for an ion is close to one when the solution has almost zero ionic strength, i.e., when the solution shows close to ideal behavior. As the ionic strength of the solution increases from 0 to 0.1 mol/L, a decrease in the...
Factors Affecting Creep01:28

Factors Affecting Creep

In normal-weight aggregate concrete, the hardened cement paste is the primary contributor to creep, whereas the aggregates, being stiffer than the cement paste, are more resilient to stress-induced deformation. The stiffness of the aggregates is defined by their modulus of elasticity, and the more voluminous they are in the concrete, the less it will creep.
Further, the water/cement ratio is critical, as a lower ratio increases concrete strength, thus reducing creep. The strength of the...
Kendall's Coefficient of Concordance01:20

Kendall's Coefficient of Concordance

Kendall's Coefficient of Concordance (W), also known as Kendall's W, is a non-parametric statistical measure used to assess the agreement or concordance between multiple raters or judges when they rank a set of items. It is often used when you have ordinal data (ranks) and you want to see if there is consistency or consensus among the raters. It is widely applied in research areas such as psychology, medicine, and social sciences, where multiple judges are asked to rank or rate subjects or...
Coefficient of Variation01:10

Coefficient of Variation

The coefficient of variation measures the dispersion of the data points or distribution around the mean. Using the coefficient of variation, we can compare two data series with drastically different means or different units of measurement. The coefficient of variation for a sample and a population is expressed as a percentage of the ratio of standard deviation to the mean.
The coefficient of variation is a practical statistical tool in finance. It allows investors to assess the volatility or...
Factors Affecting Perception01:25

Factors Affecting Perception

Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

Summary

The public's "Yuck-factor" reaction to biotechnology isn't deep wisdom but a cognitive response. Biotechnological innovations violate natural human cognitive tendencies, triggering negative emotions like disgust.

Area of Science:

  • Bioethics
  • Cognitive Science
  • Biotechnology

Background:

  • Public exhibits strong emotional reactions to biotechnology, termed the "Yuck-factor."
  • Some view this reaction as deep wisdom, while others oppose disgust-based morality.

Purpose of the Study:

  • To investigate the cognitive underpinnings of the public's negative emotional response to biotechnology.
  • To challenge the notion that the "Yuck-factor" represents innate wisdom.

Main Methods:

  • Analysis of existing theories on bioethics and public reaction.
  • Integration of findings from cognitive science regarding natural human cognitive tendencies.
  • Examination of how biotechnological processes violate these cognitive tendencies.

Main Results:

  • Strong negative emotions towards biotechnology stem from cognitive violations, not inherent wisdom.
  • Biotechnological innovations like hybridization and cloning conflict with innate "folk biology" categorization rules.
  • Violation of these cognitive rules triggers emotional responses such as fear and disgust.

Conclusions:

  • The "Yuck-factor" is a result of cognitive dissonance caused by biotechnology.
  • Understanding these cognitive violations can help address public apprehension towards biotechnological advancements.
