Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation01:26

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy  (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used.
Raman Spectroscopy Instrumentation: Overview01:26

Raman Spectroscopy Instrumentation: Overview

A conventional Raman spectrophotometer includes a laser source, a sample holding system, a wavelength selector, and a detector.
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...

Electronic Distance Measuring Instruments

Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over short distances...
Fluorescence and Phosphorescence: Instrumentation01:25

Fluorescence and Phosphorescence: Instrumentation

Fluorometers and spectrofluorometers are two types of instruments used for measuring molecular fluorescence. These instruments differ in how they select excitation and emission wavelengths and the type of light sources they utilize. Fluorometers use absorption interference filters to choose excitation and emission wavelengths. The excitation source in a fluorometer is typically a low-pressure mercury vapor lamp that emits intense lines distributed throughout the ultraviolet and visible regions.

Area of Science:

  • Medical Education Research
  • Psychometrics
  • Healthcare Professional Training

Background:

  • The Postgraduate Hospital Educational Environment Measure (PHEEM) is widely used to assess the educational environment in hospitals.
  • Understanding the psychometric properties and factor structure of PHEEM is crucial for its accurate interpretation and application across different cultural contexts.

Purpose of the Study:

  • To evaluate the reliability and characteristics of the PHEEM instrument using data from four countries: the UK, Brazil, Chile, and the Netherlands.
  • To examine the alignment between the three defined PHEEM subscales (Teaching, Role Autonomy, Social Support) and statistically derived factors.

Main Methods:

  • A large dataset of 1563 PHEEM scores was analyzed.
  • Exploratory factor analysis and reliability analysis (Cronbach's alpha) were employed.
  • Correlations were calculated between derived factors and the established PHEEM subscales.

Main Results:

  • PHEEM demonstrated high overall reliability, with a Cronbach's alpha of 0.928.
  • Exploratory factor analysis identified three primary factors.
  • These factors showed strong correlations with the Teaching (R=0.802), Role Autonomy (R=0.623), and Social Support (R=0.538) subscales, respectively.

Conclusions:

  • PHEEM is a reliable and multi-dimensional instrument for assessing postgraduate hospital educational environments.
  • The study confirms a good fit between the theoretically defined PHEEM subscales and the empirically derived factors, supporting its construct validity.
