Professional Values01:29

Professional Values

10.7K
Nurses are responsible for caring for patients during birth, death, illness, and healing. Professional values guide the decisions and actions that nurses make in their careers. If nurses know the decisions and actions to take, providing patients with exceptional care is possible.
The values that are the foundation of the nursing profession are altruism, autonomy, human dignity, and social justice.
First, altruism refers to the concern for the welfare and well-being of others without personal...

The Professional Nurse01:22

The Professional Nurse

6.5K
Professional nurses are not limited to bedside care and are taking roles of greater responsibility. A nurse should have a knowledge-based practice, including personal, theoretical, procedural, cultural, and reflexive knowledge. Additionally, nurses must be competent in cognitive, technical, interpersonal, and ethical/legal skills. Some of the best attributes of successful nurses include the following:
Communication skills: These are critical characteristics, especially speaking and listening.

Standing Waves01:17

Standing Waves

5.4K
Sometimes waves do not seem to move; rather, they just vibrate in place. Unmoving waves can be seen on the surface of a glass of milk kept in a refrigerator, which is one example of standing waves. Vibrations from the refrigerator motor create waves on the milk that oscillate up and down but do not seem to move across the surface. These waves are formed or created by the superposition of two or more identical moving waves in opposite directions. The waves move through each other, with their...

Modes of Standing Waves - I

4.0K
A close look at earthquakes provides evidence for the conditions appropriate for resonance, standing waves, and constructive and destructive interference. A building may vibrate for several seconds with a driving frequency matching the building's natural frequency of vibration; this produces a resonance that results in one building collapsing while the neighboring buildings do not. Often, buildings of a certain height are devastated, while other taller buildings remain intact. This...

Modes of Standing Waves: II01:04

Modes of Standing Waves: II

1.8K
The starting point for expressing the modes of standing waves is understanding the boundary conditions that the waves must follow. The boundary conditions are derived from the physical understanding of how the standing waves are sustained, that is, how the vibrating particles of the medium behave at the boundaries imposed on them.
For a tube open at one end and closed at the other filled with air, the modes are such that there is always an antinode at the open end and a node at the closed end....

Standing Waves in a Cavity01:28

Standing Waves in a Cavity

1.5K
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

Summary

Professionalization in evaluation can enhance stakeholder trust and evaluator reputation. However, concerns exist about a "narrowing effect" that may alienate diverse evaluators, impacting the field of evaluation.

Area of Science:

  • Evaluation Studies
  • Professional Development
  • Social Sciences

Background:

  • The professionalization of evaluation is a recurring topic in academic and professional discourse.
  • Understanding the perspectives of evaluation practitioners is crucial for navigating this evolving discussion.

Purpose of the Study:

  • To capture current American Evaluation Association (AEA) member viewpoints on the professionalization of evaluation.
  • To identify perceived benefits and drawbacks associated with evaluation professionalization.

Main Methods:

  • Qualitative in-depth interviews with AEA members.
  • Quantitative online survey distributed to AEA members.

Main Results:

  • Key benefits identified include increased stakeholder trust and enhanced evaluator reputation and identity.
  • A significant concern is the potential
  • narrowing effect
  • which could alienate evaluators based on background or competencies.

Conclusions:

  • Findings offer current insights into the AEA member perspectives on evaluation professionalization.
  • Results suggest avenues for future research on the impact and implementation of professionalization in evaluation.
