Social Media Impact on Adolescent Mental Health
Social Media and Mental Health Outcomes
The relationship between social media and mental health is complex, characterized by mixed outcomes. Use is linked to both positive factors, such as connection and identity, and negative factors, including depression and anxiety.
- Small effect sizes: The overall impact depends on specific behaviors, content, and individual traits.
- U-shaped curve: A relationship where both extremely high and extremely low use correlate with worse mental health, while moderate use
Monopoly, Monopolistic Competition and Market Price Dynamics
Monopoly — Market Structure & Price Determination
Definition
Monopoly: A market structure where a single firm controls the entire market for a product or service.
Features
- Single seller: One firm supplies the entire market.
- Unique product: No close substitutes for the product.
- Barriers to entry: High barriers prevent other firms from entering the market.
- Price maker: The firm has significant control over the price.
Equilibrium of the Firm

Fundamentals and Measurements
- SI Units: Mass (kg), Length (m), Time (s), Temperature (K), Amount (mol), Volume (m³ or L = 10-3m³).
- Prefixes: Pico (10-12), nano (10-9), micro (10-6), milli (10-3), centi (10-2), kilo (103), mega (106).
- Density: d = mass / volume. To convert g/cm³ to kg/m³, multiply by 1,000 (e.g., 6.353 g/cm³ = 6,353 kg/m³).
- Temperature Conversions: °F = (9/5)°C + 32; K = °C + 273.15 (e.g., 56.1°C = 133°F).
- Significant Figures:
- Non-zero digits are always significant. Zeros between

Shape Descriptors
Contour-Based Shape Descriptors
| Descriptor | Description |
|---|---|
| Shape Signature | Represents the shape of an object as a one-dimensional function extracted from contour points. Examples include distance to centroid, tangent angle, curvature, or arc length. It provides a compact representation for shape analysis and matching. |
| Convex Hull | Defines the smallest convex polygon enclosing the shape. It simplifies complex shapes by excluding concavities, providing a more generalized outline. Useful for |
Key Concepts in Genetics: Gene, Locus, and Allele
Key Concepts in Genetics
The Gene
A gene is organized in a linear sequence of nucleotides in the molecule of DNA (or RNA in the case of some viruses), which contains the information necessary for the synthesis of a macromolecule with specific cellular function, usually proteins, but also mRNA, rRNA, and tRNA.
The Locus
In biology, a locus is a fixed position on a chromosome, the position of a gene or a genetic marker. A variant of the DNA sequence at a given locus is called an allele. The ordered list

Understanding Health Consciousness
Health consciousness is the degree to which an individual is aware of, interested in, and actively monitors their own health while making lifestyle choices to maintain or improve their well-being. It involves a mindset where health considerations—encompassing physical, mental, and social well-being—are integrated into daily decisions about diet, exercise, stress management, and consumption habits.
