Development of Analytical Methods01:21

Development of Analytical Methods

1.9K
An analytical methodology can be divided into four sequential steps: technique, method, procedure, and protocol. A technique is a scientific principle that rationalizes a specific phenomenon through chemical measurements. Adapting a technique for analyzing a sample of interest is termed a method. The procedure outlines the directions for performing the analysis via an analytical method. The protocol is the detailed guidelines on the procedure, which should be strictly followed to obtain the...

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)01:20

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)

1.6K
Two NMR-active nuclei bonded to a central atom can be involved in geminal or two-bond coupling. Geminal coupling is commonly seen between diastereotopic protons in chiral molecules and unsymmetrical alkenes, among others.
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...

Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)01:22

Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)

1.5K
Vicinal or three-bond coupling is commonly observed between protons attached to adjacent carbons. Here, nuclear spin information is primarily transferred via electron spin interactions between adjacent C‑H bond orbitals. This generally favors the antiparallel arrangement of spins, so 3J values are usually positive.
The extent of coupling depends on the C‑C bond length, the two H‑C‑C angles, any electron-withdrawing substituents, and the dihedral angle between the involved orbitals. The...

Analyte Adsorption and Distribution01:09

Analyte Adsorption and Distribution

2.6K
In certain chromatographic separations, solutes transfer between the mobile phase and the stationary phase via sorption, which typically refers to the process of adsorption. For many chromatographic systems, the sorption process often depends on the polarity of the compounds—an expression of the overall dipole moment within the molecule. During the separation process, there is competition between the solute and solvent for adsorption to the stationary phase. Highly polar compounds and...

Jung's Analytical Theory01:23

Jung's Analytical Theory

1.1K
Carl Jung, a Swiss psychiatrist and former follower of Freud, eventually broke away from Freud's ideas to create his framework, analytical psychology. This approach emphasizes achieving a balance between the conscious and unconscious aspects of the mind and reconciling various experiences within an individual's personality. Jung believed that this process, which typically unfolds in the latter part of life, involves an ongoing journey of recognizing and incorporating unconscious...

Graphical and Analytic Representation of Sinusoids01:20

Graphical and Analytic Representation of Sinusoids

941
Analyzing two sinusoidal voltages with equal amplitude and period but different phases on an oscilloscope, an instrument used to display and analyze waveforms, involves a three-step process.
The first step is measuring the peak-to-peak value, which is twice the amplitude of the sinusoid. This provides information about the maximum voltage swing of the waveform.
Secondly, the period and angular frequency are determined. The period is the time taken for one complete cycle of the waveform, while...

Area of Science:

  • Psychology
  • Sociology
  • Family Studies

Background:

  • Dyadic research designs offer rigorous examination of relationship interdependence.
  • Specialized analytic methods are crucial for accounting for dependencies in dyadic data.
  • Limited research has applied advanced dyadic analyses to Latino populations.

Purpose of the Study:

  • To illustrate two advanced structural equation modeling approaches for analyzing distinguishable two-wave dyadic data.
  • To examine the longitudinal associations between somatic symptoms and marital negativity in Mexican-origin couples.
  • To highlight the importance of culturally relevant research designs for diverse populations.

Main Methods:

  • Employed dyadic matched-pairs research design with parallel data from husbands and wives.
  • Utilized structural equation modeling, specifically a hybrid actor-partner interdependence model and a difference model.
  • Analyzed longitudinal data from 246 Mexican-origin marital dyads on somatic symptoms and marital negativity over five years.

Main Results:

  • Spouses' somatic symptoms predicted increases in their partners' marital negativity five years later.
  • Wives' prior marital negativity predicted greater discrepancies in marital negativity over time.
  • Husbands' prior marital negativity predicted fewer discrepancies in marital negativity over time.

Conclusions:

  • Prospective dyadic data designs are beneficial for studying interdependence in Latino populations.
  • Findings underscore the interconnectedness of individual well-being and relationship dynamics in Mexican-origin families.
  • Advanced statistical modeling can reveal nuanced patterns of influence within marital dyads.
