Sustainable Development

14.8K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Steps in the Modeling Process

653
Albert Bandura's theory of observational learning identifies four critical processes: attention, retention, motor reproduction, and reinforcement or motivation.
Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying. For example, if you decide to take a drawing class to enhance your skills, you need to pay close attention to the instructor's words and hand movements. The characteristics of the model significantly...

Design Example: Sustainability in Concrete Building

394
As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

834
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

In Vitro Drug Dissolution: Compendial Testing Models I01:13

In Vitro Drug Dissolution: Compendial Testing Models I

246
Compendial dissolution methods are standardized procedures defined by pharmacopeias to evaluate the rate at which a drug dissolves in a specific medium. These methods ensure batch-to-batch consistency, enable quality control, and support the prediction of drug bioavailability. They are critical for both immediate and modified-release drug products.The apparatuses used for dissolution testing differ in their design and mechanical function, but all aim to simulate the physiological environment of...

In Vitro Drug Dissolution: Compendial Testing Models II01:09

In Vitro Drug Dissolution: Compendial Testing Models II

284
Various dissolution methods are utilized to assess a drug’s dissolution rate, including the flow-through cell, paddle-over-disk, cylinder, and reciprocating disk methods.The flow-through cell apparatus (USP (United States Pharmacopeia) method 4) comprises a reservoir for the dissolution medium and a pump that propels the medium through the cell containing the test sample. This method is crucial for assessing modified-release dosage forms with minimally soluble active ingredients,...

Area of Science:

  • Cognitive Psychology
  • Psychometrics
  • Neuroscience

Background:

  • Sustained attention is crucial for many cognitive tasks.
  • Existing models often lack detailed validation of underlying sub-components.
  • Experimental test validation calls for a more granular understanding of attention processes.

Purpose of the Study:

  • To propose and validate a process model for sustained attention tests.
  • To identify and assess the contribution of four postulated sub-components: perception, mental operation, motor reaction, and item shifting.
  • To determine the predictive validity of these sub-components for sustained attention and higher cognitive abilities.

Main Methods:

  • Development and validation of a process model for sustained attention.
  • Application of various cognitive tasks and modified d2-R tests across two studies.
  • Assessment of the contribution of proposed sub-components to performance prediction.

Main Results:

  • The process model sub-components explained a substantial variance (55-74%) in sustained attention tests.
  • Perceptual and mental operation speed emerged as the strongest predictors of performance.
  • Motor speed showed a minor influence, while item shifting measures had low reliability and predictive power.

Conclusions:

  • This study is the first to successfully disentangle sub-components within sustained attention tests.
  • The validated model highlights the critical roles of perceptual and mental operation speed.
  • Results demonstrate good discriminant validity, showing sub-components do not overly explain variance in working memory or reasoning tasks.
