Self-Concept

1.7K
Self-concept is the cognitive and emotional understanding individuals hold about their identity. It evolves through various developmental stages, beginning in infancy and maturing as children grow. This concept influences how individuals perceive their abilities, interact with others, and manage challenges throughout life.
Infancy and Emerging Recognition
During infancy, self-concept is virtually nonexistent. Babies do not distinguish themselves as separate entities and often mistake their...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

Concept of Pressure at a Point

795
The concept of pressure at a point in a fluid establishes that pressure within a fluid is uniform in all directions at a specific location. This uniformity occurs because fluid molecules exert force evenly across any point due to their random motion and continuous collisions within the fluid. Pressure at a point is determined by the surrounding fluid molecules and is influenced by factors like depth and density, rather than by shape or orientation.
In a fluid at rest, pressure acts equally in...

Area of Science:

  • General and Family Medicine
  • Medical Ethics
  • Public Health

Background:

  • Quaternary prevention, as defined by Wonca, focuses on identifying patients at risk of overmedicalization and protecting them from unnecessary medical interventions.
  • The concept was introduced by Marc Jamoulle, initially targeting patients with illness but no definitive disease.

Purpose of the Study:

  • To stimulate discussion on a revised definition and conceptual model for quaternary prevention.
  • To emphasize the importance of integrating quaternary prevention into physicians' considerations for all patient interventions.

Main Methods:

  • This is an opinion article, presenting a conceptual argument and proposing a new definition.
  • Literature review and conceptual analysis to support the proposed model.

Main Results:

  • The current definition of quaternary prevention has limitations, excluding scenarios where it could be beneficial.
  • Harm can result from medical interventions at any stage of life, including healthy periods, self-limited diseases, chronic conditions, and terminal illnesses.

Conclusions:

  • A new definition of quaternary prevention is proposed: 'action taken to protect individuals (persons/patients) from medical interventions that are likely to cause more harm than good.'
  • This expanded definition aims to encompass a wider range of situations where patient protection from medical harm is necessary.
  • The ongoing debate on quaternary prevention is crucial for contemporary medicine, highlighting the need for broader application to safeguard patient well-being.
