Cross-Sectional Research01:50

Cross-Sectional Research

12.1K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Stratified Sampling Method01:16

Stratified Sampling Method

13.7K
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. 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.
To choose a stratified sample, divide the population into groups called strata and then take a...

Longitudinal Research

12.8K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Cluster Sampling Method01:20

Cluster Sampling Method

13.4K
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 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...

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Summary
This summary is machine-generated.

This study introduces bi-national link-tracing sampling for transnational social fields, revealing that nomination patterns in migration networks are influenced by sex and residence. This advances social network analysis in migration research.

Area of Science:

  • Social Sciences
  • Sociology
  • Network Science

Background:

  • Studying transnational social fields, which include migrants, returned migrants, and non-migrants, presents unique sampling challenges.
  • Existing methodologies may not fully capture the complex, interconnected nature of these international networks.

Purpose of the Study:

  • To advance the bi-national link-tracing sampling design for data collection within transnational social fields.
  • To empirically implement and evaluate this innovative methodology for studying international migration networks.
  • To guide future research by analyzing the features of networks generated through this sampling method.

Main Methods:

  • Developed and applied a bi-national link-tracing sampling design.
  • Conducted 303 face-to-face structured interviews in a Romanian sending community and a Spanish receiving town.
  • Constructed a multi-layered complex network with 4,855 nominated individuals, 5,477 directed ties, and 2,540 edges.

Main Results:

  • The link-tracing nomination patterns within the constructed network were found to be influenced by sex homophily.
  • Residence homophily also significantly affected nomination patterns in the transnational networks.
  • The study successfully generated a complex network structure representing interconnected personal networks.

Conclusions:

  • The bi-national link-tracing sampling design is a viable and effective method for studying transnational social fields.
  • Social network analysis, utilizing this methodology, offers valuable insights into the dynamics of international migration.
  • Future research can leverage this approach to further explore migration-related social structures.
