Free-falling Bodies: Example01:05

Free-falling Bodies: Example

An object falling without any air resistance under the influence of gravitational force is said to be in free-fall. For free-falling bodies, the acceleration due to gravity is constant, irrespective of their mass. Free-fall is experienced not only by objects falling downward, but also by all objects whose motion is influenced by gravitational force alone. The dynamics of free-fall motion can be calculated using kinematic equations of motion, since free-fall acceleration is constant.

Profile Leveling and Cross Sections01:26

Profile Leveling and Cross Sections

Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes.  Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the instrument's...

Free-falling Bodies: Introduction

All objects, neglecting air resistance, fall with the same acceleration towards the Earth's center due to the force exerted by the Earth's gravity. This experimentally determined fact is unexpected because we are so accustomed to the effects of air resistance and friction that we expect light objects to fall slower than heavier ones. People believed that a heavier object had a greater acceleration when falling until Galileo Galilei (1564–1642) proved otherwise. We now know this is not the case.
Self-Presentation: Self-Monitoring and Self-Handicapping02:05

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about the way you...
Life Histories01:29

Life Histories

Constrained by limited energy and resources, organisms must compromise between offspring quantity and parental investment. This trade-off is represented by two primary reproductive strategies; K-strategists produce few offspring but provide substantial parental support, whereas r-strategists produce much progeny that receives little care. These strategies are related to an organism’s survival likelihood across its lifespan, which is represented by a survivorship curve. Three general types of...
Survival Tree01:19

Survival Tree

Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Area of Science:

  • Gerontology
  • Public Health
  • Epidemiology

Background:

  • Falls are a significant concern for community-dwelling older adults, leading to injury and loss of independence.
  • Identifying specific fall typologies and associated risk factors is crucial for effective prevention.

Purpose of the Study:

  • To categorize different types of falls experienced by women aged 75 and older.
  • To determine if distinct faller profiles can be identified within this demographic.

Main Methods:

  • A prospective cohort study followed 727 women aged 75+ over four years.
  • Participants were contacted regularly, with fall details collected via questionnaire to minimize recall bias.
  • Multiple correspondence analysis and clustering were used to identify fall typologies.

Main Results:

  • Four distinct fall clusters emerged: outside falls (attention-related, environmental factors), inside falls (frailty-related), and falls from height.
  • Outside falls linked to attention affected 28% of women, environmental factors 16%, frailty-related inside falls 44%, and falls from height 11%.
  • Each fall type correlated with specific health and functional statuses, including dependence, mobility issues, and use of walking aids.

Conclusions:

  • Older women exhibit diverse fall and faller profiles, ranging from those associated with frailty to hyperactivity.
  • Tailoring fall prevention programs based on these identified profiles could significantly improve outcomes for the elderly.
