Conservation of Small Populations02:04

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less likely to...
Conservation of Declining Populations02:07

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.
What are Populations and Communities?00:30

What are Populations and Communities?

Populations are groups of individuals of the same species that inhabit a shared environment. Communities include multiple co-existing, interacting populations of different species. Metapopulations span multiple populations of the same species that occupy different areas. Metapopulations interact through immigration and emigration, providing genetic diversity that lends resilience to harsh environments. Population size and density can be estimated using quadrat and mark and recapture...
Random Sampling Method01:09

Random Sampling Method

Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest. Among the various sampling methods used by...
Cluster Sampling Method01:20

Cluster Sampling Method

Appropriate sampling methods ensure that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. All the members from these clusters are in the cluster sample. For example, if you randomly sample four departments from your...
Sampling Plans01:23

Sampling Plans

Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...

Area of Science:

  • Nursing Research
  • Social Sciences
  • Public Health

Background:

  • Rare populations and socially excluded groups present significant sampling challenges in research.
  • Nurses, due to their direct patient care roles, are uniquely positioned to access and study these hard-to-reach populations.
  • Understanding and addressing the needs of socially excluded individuals requires effective research methodologies.

Purpose of the Study:

  • To discuss the challenges associated with sampling rare and socially excluded populations.
  • To highlight the potential role of nurses in conducting research with these groups.
  • To review various sampling methods applicable to hard-to-reach populations.

Main Methods:

  • Exploration of established and innovative sampling techniques.
  • Discussion of strategies for recruitment and data collection in marginalized communities.
  • Case examples illustrating the application of different sampling approaches.

Main Results:

  • Various sampling methods can be adapted for rare and socially excluded populations.
  • Nursing interventions can facilitate access and engagement with hard-to-reach individuals.
  • Successful sampling requires tailored approaches considering population characteristics and ethical considerations.

Conclusions:

  • Nurses are vital in overcoming sampling barriers for socially excluded groups.
  • Effective sampling strategies are essential for advancing research in underrepresented populations.
  • Further development and application of appropriate sampling methods are needed to ensure inclusivity in research.
