Longitudinal Studies01:26

Longitudinal Studies

456
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...

Longitudinal Research

13.0K
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...

Data: Types and Distribution

1.5K
In biostatistics, data are the observations collected for analysis. There are two main types: parametric and non-parametric. Parametric data, which include continuous (e.g., weight) and discrete numerical data (e.g., number of tablets), assume a particular distribution pattern, often the normal distribution. Non-parametric data do not adhere to a specific distribution and typically comprise nominal (e.g., gender) and ordinal categorical data (e.g., pain scale ratings).

Sources of Law01:26

Sources of Law

1.8K
Laws form the essential rules set by governing authorities to shape and control societal behavior. In nursing, laws guide actions, safeguard patient rights, define nurses' scope of practice, and maintain professional standards. Understanding the legal framework governing nursing involves recognizing four primary sources of law: constitutional, statutory, administrative (regulatory), and common law.
Constitutional law is foundational, deriving from federal and state constitutions, and...

Lateralization01:28

Lateralization

949
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Distributions to Estimate Population Parameter01:26

Distributions to Estimate Population Parameter

5.0K
The accurate values of population parameters such as population proportion, population mean, and population standard deviation (or variance) are usually unknown. These are fixed values that can only be estimated from the data collected from the samples. The estimates of each of these parameters are sample proportion, the sample mean, and sample standard deviation (or variance). To obtain the values of these sample statistics, data are required that have particular distribution and central...

Area of Science:

  • Political Science
  • Latin American Studies
  • Legislative Studies

Background:

  • Understanding legislative behavior and composition is crucial for democratic governance.
  • Existing data on Latin American legislators is fragmented, hindering comparative analysis.
  • A comprehensive dataset is needed to study legislative elites across the region.

Purpose of the Study:

  • To introduce and describe the Latin American Legislators Dataset.
  • To provide a centralized resource for researchers studying legislative elites in Latin America.
  • To facilitate analysis of legislator attributes such as gender, elite turnover, seniority, and inter-chamber switching.

Main Methods:

  • Data collection encompassing elected legislators in 18 Latin American countries.
  • Inclusion of data from unicameral and bicameral legislatures (lower and upper chambers).
  • Data spans from 1978 or democratic transition until 2023, covering 259 elections.

Main Results:

  • The dataset comprises 31,724 observations of 21,807 unique legislators.
  • It includes detailed attributes on legislator gender, elite turnover, seniority, and inter-chamber switching.
  • The dataset covers legislative elections in 18 Latin American countries.

Conclusions:

  • The Latin American Legislators Dataset is a valuable and extensive resource for political science research.
  • It enables in-depth analysis of legislative elites and democratic processes in Latin America.
  • The dataset supports comparative studies on legislative behavior and composition.
