What is an Experiment?

19.1K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Thomson's e/m Experiment

6.9K
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

Nursing Interventions I: Taxonomy of Nursing Interventions

3.9K
Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...

Controls in Experiments

18.4K
When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

Randomized Experiments01:13

Randomized Experiments

9.1K
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Crossover Experiments01:16

Crossover Experiments

4.6K
Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.

    Summary

    Military nurses faced extreme conditions and ethical challenges in Iraq, highlighting the gap between formal education and battlefield realities. This experience underscores the need for comprehensive training that addresses the psychological and ethical demands of deployment.

    Area of Science:

    • Military Medicine
    • Nursing Ethics
    • Trauma Care

    Background:

    • Extensive military nursing careers do not fully prepare individuals for deployment realities.
    • The Iraq deployment presented unique challenges beyond typical nursing education.

    Purpose of the Study:

    • To describe the unprepared experiences of a military nurse during deployment to Iraq.
    • To highlight the impact of extreme living conditions, battlefield injuries, and ethical dilemmas.

    Main Methods:

    • Qualitative reflection on personal deployment experiences.
    • Narrative description of encountered situations.

    Main Results:

    • Confrontation with extreme living conditions.
    • Exposure to harrowing battlefield injuries.
