Critical Thinking01:19

Critical Thinking

Critical thinking involves reflective and productive thinking and the evaluation of evidence. Critical thinkers seek to understand the deeper meaning of ideas, question assumptions, and make independent decisions about what to believe or do. Scientists, for instance, are often critical thinkers. Critical thinking also requires humility about what we know and don't know and the motivation to look beyond the obvious. It is essential for effective problem-solving.

Key Elements for Plant Nutrition02:35

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the atmosphere, the...
Methods to Assess Microbial Communities01:19

Methods to Assess Microbial Communities

Microbial communities, comprising bacteria, archaea, and eukaryotic microorganisms, inhabit diverse ecosystems and play crucial roles in environmental and biological processes. Their diversity is defined by three main parameters: species richness (the number of distinct species), species abundance (the relative quantity of each species), and species evenness (how uniformly individual species are distributed in various locations). These factors together shape the structure and ecological balance...

Assessment of Social Transmission of Food Preferences Behaviors

Published on: January 25, 2018

Area of Science:

  • Public Health
  • Systems Science
  • Community Nutrition

Background:

  • Food and nutrition insecurity arises from fragmented systems, with stakeholders often working in silos.
  • Addressing complex food systems requires holistic interventions that integrate diverse perspectives.

Purpose of the Study:

  • To gain insights into food and nutrition insecurity in Los Angeles using participatory group model building.
  • To assess the impact of group model building workshops on stakeholder perspectives and understanding of food system drivers.

Main Methods:

  • Utilized participatory group model building with 24 multi-sector stakeholders over three workshops.
  • Constructed a systems map with 69 variables across 10 constructs and three ecological levels.
  • Administered pre- and post-workshop surveys to measure shifts in stakeholder perceptions.

Main Results:

  • A systems map was co-created, revealing key drivers and intervention areas for food and nutrition insecurity.
  • Pre-workshop, stakeholders emphasized individual-centric factors; post-workshop, community and structural factors were identified as primary drivers.
  • Workshop participation led to a significant shift in understanding the systemic nature of food and nutrition insecurity.

Conclusions:

  • Group model building effectively integrates diverse stakeholder perspectives to understand complex food systems.
  • Stakeholder understanding evolved from individualistic to systemic views of food and nutrition insecurity drivers.
  • This approach fosters a more cohesive, systems-level strategy for addressing food and nutrition insecurity.
