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

Self-Evaluation: Self-Enhancement and Self-Verification

5.8K
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...

Protection of Alcohols

8.1K
This lesson delves into the concept of protection and deprotection of a functional group fundamental to synthetic organic chemistry. These phenomena are explained in the context of aliphatic and aromatic alcohols.
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...

Zones of Protection01:16

Zones of Protection

793
In power systems, the entire setup is divided into protective zones to isolate faults and protect the rest of the network. These zones include generators, transformers, buses, transmission lines, distribution lines, and motors. Each zone can be visualized as a separate room in a house, with each room protected by its own circuit breaker.
Protective zones are defined by closed dashed lines, containing one or more components. A key characteristic of these zones is the strategic placement of...

Radial System Protection01:23

Radial System Protection

439
Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system.
In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

Protecting Self-Esteem01:27

Protecting Self-Esteem

209
Self-esteem, a central component of psychological well-being, is actively maintained through various cognitive and behavioral strategies. Individuals employ specific mechanisms to preserve a positive self-concept and mitigate threats to their self-worth, particularly in contexts involving social evaluation or personal feedback. Four primary techniques are commonly used to sustain self-esteem.Manipulating AppraisalsOne prominent strategy involves manipulating appraisals from others. Individuals...

Line Protection with Impedance Relays01:27

Line Protection with Impedance Relays

451
Coordinating time-delay overcurrent relays in complex radial systems and directional overcurrent relays in multi-source transmission loops can be challenging. Impedance relays address these issues by responding to the voltage-to-current ratio, specifically measuring the apparent impedance of a line. These relays become more sensitive during faults as current increases and voltage decreases, thereby reducing the apparent impedance.
Under normal conditions, low load currents keep the measured...

Area of Science:

  • Biomedical and behavioral research ethics
  • Regulatory science
  • Public health policy

Background:

  • The U.S. Department of Health and Human Services revised the Common Rule in January 2017.
  • Experts in research ethics were invited to comment on significant changes.
  • Authors possess extensive experience in institutional leadership, ethics advisory bodies, and Institutional Review Boards (IRBs).

Purpose of the Study:

  • To critically evaluate key modifications within the revised Common Rule.
  • To address implications of definitional ambiguities and new regulatory requirements.
  • To foster discussion on ethical considerations in human subjects research under the updated regulations.

Main Methods:

  • Expert commentary and analysis of the revised Common Rule.
  • Drawing on practical experience in research ethics and oversight.
  • Scholarly review of specific regulatory changes and their potential impact.

Main Results:

  • Concerns identified regarding the distinction between research and quality improvement activities.
  • Debate on using "generalizable knowledge" to differentiate research from clinical care.
  • Ethical and practical issues raised concerning research on and use of posted consent forms.
  • Critique of the mandatory single IRB (sIRB) review for multisite studies.

Conclusions:

  • The revised Common Rule presents ongoing challenges with definitions and implementation.
  • Further examination is needed regarding consent form data utilization and privacy.
  • The single IRB mandate requires careful consideration of its impact on multisite research oversight and ethics.
