Core Concepts of Accrual Accounting

Accrual accounting dictates that we record revenue when we have actually delivered the product or service—not when the customer pays.

Fundamental Accounting Equations

• Balance Sheet: Assets = Liabilities + Equity
• Income Statement: Revenue - Expenses = Net Income

The income statement does not include dividends. A consolidated balance sheet represents the total of the parent company and all its subsidiaries.

Financial vs. Tax Reporting

Firms must maintain at least two sets of books:

• Financial Reporting (GAAP): For investors and external users.
• Tax Reporting (Tax Code): For determining taxable income.

Robinson Crusoe: A Study of Individualism

This fragment belongs to the first chapter of Robinson Crusoe (1719), written by Daniel Defoe. It is considered one of the first modern English novels. The text is a prose narrative, written in the form of an autobiographical account, which gives it realism and credibility.

The novel was published in the early 18th century, during a period of commercial expansion, colonial growth, and the rise of the middle class in England. Although the story begins in 1632, it reflects the values of Defoe’s own time:

• Individualism
• Economic ambition
• Social mobility

These ideas are connected to the Enlightenment, which promoted reason, self-improvement, and personal responsibility. In this fragment, Crusoe introduces his... Continue reading "Literary and Historical Analysis: Defoe and Jefferson" »

John Locke: The Foundations of Civil Government

This text is an extract from Second Treatise of Civil Government (1690) by John Locke. It is a political and philosophical work in which Locke explains the origin and purpose of political society and government. He defends the idea that government is based on natural rights and the consent of the people, rejecting absolutism and the divine right of kings.

Historical Context and Political Theory

The historical context is late 17th-century England, specifically the period surrounding the Glorious Revolution, when Parliament limited the power of the monarchy. Locke’s ideas are central to the Enlightenment and support constitutional government.

The Transition from the State of Nature

The Magic of Halloween Traditions

Halloween is celebrated every year on the night of October 31. A long time ago, it started as an ancient festival to mark the end of the harvest. Today, it has changed, and it is mostly about having fun with scary things and imagination.

Patriarchal Control in Jamaica Kincaid’s Girl

Imagine being prepared for adulthood before you are allowed to figure yourself out. In Jamaica Kincaid’s Girl, patriarchal social values are introduced through a mother’s constant instructions. Kincaid uses the story’s single-sentence structure, repetition, and minimal dialogue to demonstrate how gender expectations are imposed on girls through constant pressure that teaches them their value depends on domestic skills and controlled behavior.

The Suppression of Voice

Control often begins by limiting a girl’s voice. The story’s structure makes that imbalance unavoidable. Although the daughter briefly protests with, “I don’t sing benna,” her voice is instantly spoken over by the mother'...
