Self-Evaluation: Self-Enhancement and Self-Verification03:00

Self-Evaluation: Self-Enhancement and Self-Verification

5.7K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Strategies of Self-Presentation II: Self-Verification

174
Self-verification is a fundamental psychological drive wherein individuals seek affirmation of their self-concept from others, striving for consistency between their internal self-view and external perceptions. This drive operates even when the self-concept is negative, influencing interpersonal behavior and feedback preferences in complex and often counterintuitive ways. Unlike the self-enhancement motive, which seeks positive evaluations, self-verification prioritizes coherence and...

Leveling Equipment

As leveling involves measuring vertical distances relative to a horizontal line of sight, it requires a graduated rod, called a level rod, for vertical measurements and an instrument called a level for a horizontal sight line. A level includes a high-powered telescope with a mechanism for leveling to ensure the line of sight is horizontal when the bubble in the spirit level is centered. Leveling rods, made of wood, metal, or fiberglass, are graduated in feet or meters and commonly used in two-...

Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:

Equipments Used to Measure Body Temperature

1.7K
Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

Equipments Used To Measure Blood Pressure

3.1K
Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Area of Science:

  • Biometrics and Human-Computer Interaction
  • Pattern Recognition and Machine Learning
  • Computer Vision and Image Processing

Background:

  • Biometric verification systems are increasingly prevalent.
  • Existing systems often rely on single biometric traits, which can have limitations.
  • Theoretical advancements necessitate exploring more robust verification methods.

Purpose of the Study:

  • To propose and experimentally evaluate a novel multi-biometric system for laboratory testing.
  • To integrate hand contour and blood flow (blood stream) as biometric characteristics.
  • To assess the impact of metric consolidation on system precision.

Main Methods:

  • Designed a multi-biometric system utilizing hand contour and upper hand blood flow.
  • Detailed the hardware and software components of the proposed system.
  • Evaluated individual and consolidated metrics, comparing frequency of double-type faults with Equal Error Rate (EER) values.
  • Experimented with Hamming distance and Maximally Helicity Violating (MHV) metrics.

Main Results:

  • The Maximally Helicity Violating (MHV) metric showed the lowest value.
  • Consolidating metrics demonstrated improved system precision compared to individual metrics.
  • The multi-biometric system achieved an Equal Error Rate (EER) of 5%.
  • Individual algorithms showed significant accuracy but performed better when consolidated.

Conclusions:

  • Metric consolidation is crucial for enhancing the precision of multi-biometric systems.
  • The proposed system demonstrates the effectiveness of combining hand contour and blood flow biometrics.
  • While individual metrics are accurate, their combined application yields superior performance, despite minor shortcomings.
