Self-Evaluation Maintenance Model01:29

Self-Evaluation Maintenance Model

The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Concepts of Health and Illness

Health is a condition of the body, mind, and spirit where an individual remains free from illness. Similarly, wellness is an active state, including living a lifestyle that promotes physical, mental, and emotional health. Physical health is critical for the overall well-being and can be affected by lifestyle, activity level, diet, and behavior. The highest attainable standard of health is a fundamental and universal human right. Consider Lisa, a fifteen-year-old born with congenital...

Models of Health Promotion and Illness Prevention I

A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...

Models of Health Promotion and Illness Prevention II

The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results from...

Mechanistic Models: Compartment Models in Individual and Population Analysis

Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least squares (OLS)...

Mechanistic Models: Overview of Compartment Models

Mechanistic models, a category encompassing both physiological and compartmental modeling, differ from empirical models' approaches to incorporating known factors about the systems being modeled. Empirical models describe data with minimal assumptions, while mechanistic models aim to provide a robust description of available data by specifying assumptions and integrating known factors about the system. Compartmental analysis is a key example of a mechanistic model in pharmacokinetics and...

Area of Science:

  • Environmental Science
  • Ecotoxicology
  • Resource Management

Background:

  • Coal mining operations, particularly in western Canada, can release significant amounts of selenium (Se).
  • Selenium contamination poses risks to both aquatic and terrestrial ecosystems.
  • Existing management strategies may lack a comprehensive, integrated approach.

Purpose of the Study:

  • To present a conceptual selenium (Se) management model.
  • To provide a framework for integrating and synthesizing existing information on Se.
  • To support adaptive management of ecological exposures and risks associated with Se.

Main Methods:

  • Development of a conceptual model for Se management.
  • Focus on coal mining in western Canada, with broader applicability.
  • Integration of information on Se sources, release, pathways, and receptors.

Main Results:

  • The model offers a transparent and structured process for Se management.
  • It facilitates visualization and development of interventions for Se control.
  • Identifies critical information needs for effective risk reduction.

Conclusions:

  • The conceptual Se management model provides a foundation for decision-making.
  • It enhances understanding of interrelationships between environmental media and receptors.
  • Applicable to coal mines and other industrial Se sources, with modifications.
