Self-Presentation: Self-Monitoring and Self-Handicapping02:05

Self-Presentation: Self-Monitoring and Self-Handicapping

42.5K
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Design Example: Resistive Touchscreen

562
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

Social Facilitation01:04

Social Facilitation

34.9K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Muscles for Facial Expressions01:14

Muscles for Facial Expressions

3.7K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

Sympathetic Signaling01:31

Sympathetic Signaling

1.5K
Sympathetic signaling, a vital part of the autonomic nervous system, plays a crucial role in mobilizing the body's resources in response to stress or emergencies. It involves the transmission of nerve impulses from sympathetic preganglionic fibers to postganglionic fibers. This results in the release of specific neurotransmitters and activation of adrenergic receptors.
Sympathetic preganglionic fibers release the neurotransmitter acetylcholine (ACh) onto the ganglionic neurons in the...

Instantaneous Power01:22

Instantaneous Power

661
Instantaneous power is important in electrical circuits, mainly when dealing with sinusoidal input. Instantaneous power, denoted as p(t), results from the multiplication of the instantaneous voltage (v(t)) across an element and the instantaneous current (i(t)) flowing through it. This relationship adheres to the passive sign convention and represents a fundamental principle in electrical engineering.

Area of Science:

  • Educational Technology
  • Computer Science

Background:

  • COVID-19 necessitated a shift from face-to-face to remote teaching.
  • Existing web conferencing tools have limited 'raise hand' functions, often missed by lecturers.
  • Reduced student-lecturer interaction impacts learning effectiveness in remote settings.

Purpose of the Study:

  • To develop an improved 'raise hand' function for remote lectures.
  • To enhance student-lecturer interaction during online teaching.
  • To create a non-intrusive visual cue for student questions within presentation software.

Main Methods:

  • Utilized Microsoft PowerPoint's Visual Basic for Applications (VBA) for programming.
  • Developed a background routine to monitor a web-based 'signal file'.
  • Enabled students to trigger a visual alert by modifying the signal file via URL.

Main Results:

  • A novel 'raise hand' feature was successfully implemented directly within PowerPoint.
  • The system generates a clear, customizable visual signal visible to the lecturer.
  • The signal is independent of the web conferencing system being used.

Conclusions:

  • The developed PowerPoint-based system effectively addresses the limitations of standard remote teaching interaction.
  • Lecturers can now respond instantly to student questions, improving real-time engagement.
  • This solution enhances the educational experience in online learning environments.
