Should AI Be Prohibited at Universities? Regulation vs Bans
Should AI Be Prohibited at Faculties?
AI is now a normal part of academic life, and universities must decide how to respond. My thesis is that AI should not be prohibited at faculties, but used and regulated wisely. Firstly, AI helps students learn better and work faster. Secondly, banning AI simply does not work in practice. On the other hand, some argue that AI can hurt critical thinking and lead to cheating, and this concern has some value. In conclusion, faculties should regulate AI, not prohibit
Contraception and Emergency Contraception Clinical Reference
Contraception and UKMEC Guidelines
- COCP – increases the risk of breast and cervical cancers, decreases the risk of ovarian and endometrial cancer.
- After giving birth, women need contraception after day 21.
Progestogen-Only Pill (POP)
- The FSRH advises postpartum women (breastfeeding and non-breastfeeding) can start the POP anytime after postpartum.
- After day 21, additional contraception should be used for the first 2 days.
- A small amount of progestogen enters breast milk, but this is not harmful to the
Silicon Valley Meritocracy, Power, and Justice Analyzed
The Myth of Meritocracy in Silicon Valley
Anand Giridharadas uses his review of Theo Baker’s How to Rule the World to show that although individuals and institutions in the Bay Area (i.e., Silicon Valley and Stanford) are avid proponents of meritocracy, in fact, old boys’ networks and money ultimately determine people’s fate. There is little to no accountability in such a system, and as a result, powerful individuals get away with a lot. People in such systems believe that powerful individuals

Understanding Earthquake Mechanics, Plate Tectonics, and Building Seismic Behavior
1. A. Elastic Rebound Theory of an Earthquakes
- Continuous Plate Movement: Tectonic plates are continuously moving due to forces acting inside the Earth.
- Stress Accumulation: Rocks along a fault may be locked due to friction, while the plates continue to move. This causes stress to accumulate.
- Elastic Deformation: The rocks slowly bend and deform because of the increasing stress and store elastic strain energy.
- Breaking Point: When the accumulated stress becomes greater than the strength and frictional

Strategic Management Masterclass: Frameworks and Analysis
Part 1: Fundamentals of Strategic Management
1.1 Defining Strategy and Competitive Advantage
Strategy is not a static document but a set of dynamic ideas, plans, decisions, and actions that enable an organization to succeed and create a sustainable competitive advantage. A strategy must diagnose the competitive challenge, provide a guiding policy to address it, and implement a set of coherent actions.
Competitive Advantage: This occurs when a firm generates superior value for customers relative to
