Longitudinal Studies01:26

Longitudinal Studies

265
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

12.6K
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...

Biological Clocks and Seasonal Responses02:45

Biological Clocks and Seasonal Responses

39.4K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Meridians01:28

Meridians

535
In surveying, meridians are vital reference lines to measure directions and establish accurate land orientations. Meridians run from the north to the south poles, providing a stable framework for angular measurements and mapping. Meridians are fundamental in survey design, with the primary types being astronomic, magnetic, and assumed meridians. Each type offers distinct benefits and limitations, selected based on the project's scale and precision needs.The astronomic meridian is aligned with...

Lateralization01:28

Lateralization

552
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.

Magnetic Declination01:19

Magnetic Declination

134
Magnetic declination is the angle between true north, which aligns with the Earth's rotational axis, and magnetic north, which follows the direction of the Earth's magnetic field. This discrepancy exists because the magnetic poles do not coincide with the geographic poles. The value of magnetic declination depends on the observer's location on Earth and is subject to changes over time due to the dynamic nature of the Earth's magnetic field.The declination is called eastern when magnetic north...

Area of Science:

  • Chronobiology
  • Public Policy

Background:

  • Debate over abolishing Daylight Saving Time (DST) is ongoing globally.
  • Governments are considering permanent DST or standard time, with sleep experts favoring standard time.

Discussion:

  • Alberta's 2021 referendum on permanent DST revealed geographic and demographic preferences.
  • A geospatial analysis showed an East-West gradient in support, with smaller, northern communities favoring permanent DST.

Key Insights:

  • Geographic location significantly influences public opinion on DST.
  • Eastern and smaller, northern communities showed greater preference for year-round DST.

Outlook:

  • Findings can inform public advocacy by chronobiology and sleep science communities.
  • Understanding geospatial preferences is crucial for policy decisions on time changes.
