Notes, summaries, assignments, exams, and problems for University

1. Core Definitions

• Dialect: A regional or social variety with unique grammar, vocabulary, and pronunciation.
• Variety (Code): A neutral umbrella term for any form of language, including dialects and registers.
• Repertoire: The full toolbox of linguistic resources an individual can use.
• Register: Specialized language for specific jobs or topics (e.g., Legalese).
• Style: Language variation based on context, goals, or the audience.

2. The Big Four: Style and Units of Analysis

William Labov (1st Wave)

• Style: Attention to speech. Monitoring yourself makes you more formal.
• Unit: Speech Community. A group sharing the same language norms and rules.

Alan Bell

• Style: Audience Design. You adapt your speech based on your listeners.

Lesley Milroy (2nd Wave)

• Unit: Social

Unit 1: The Beat Generation and Post-War Culture

The post-WWII era was defined by the Cold War, the Red Scare, suburbanization, and the rise of consumerism. In response, the Beat Generation (including the New York Beats and Beatniks) emerged, challenging social norms through themes of self-expression, madness, non-conformity, and alternative realities.

• Jack Kerouac: Author of On the Road (1957). He utilized "spontaneous prose" to capture raw thought and experience. His work features the roman-à-clef style, travel narratives, and the archetype of the Beat hero.
• Joyce Johnson: Author of Minor Characters (1983). Her memoir offers a female reinterpretation of the Beat era, focusing on the experiences of women within the male-dominated literary circle

Sorting

Stable vs In-Place

Stable: The relative order of elements with the same key value is preserved by the algorithm.

If after the first sort, an element is at its final position and subsequent iterations do not change its position, it is considered stable.

In-Place: Requires only a constant amount, i.e., O(1), of extra space during the sorting process.

Assigning a temporary variable takes up a small amount of constant space but is still counted as in-place.

Sorting Explanations

Merge Sort: For arrays, it requires significant space, but for Linked Lists, due to pointer manipulations, it does not require extra space.

Selection Sort: In each iteration, find the smallest element and swap it with the first index. Subsequent iterations process n-1 elements... Continue reading "Sorting Algorithms and Hashing Techniques" »

Q1. Time Series Forecasting Methods Comparison

Time Series Components

• Trend (T)
• Seasonality (S)
• Cyclical (C)
• Random (R)

Forecasting Methods

Naïve Method

Formula: Ft+1 = At

• Assumes next demand equals last demand.
• Used as a benchmark.

Simple Moving Average (n)

Formula: Ft+1 = (At + At-1 + … + At-n+1) / n

• Smooths random variation.
• A higher 'n' increases lag.

Weighted Moving Average

Formula: Ft+1 = w1At + w2At-1 + … + wnAt-n+1

• Sum of weights (Σw) equals 1.
• Recent data is given a higher weight.

Exponential Smoothing

Formula: Ft+1 = αAt + (1−α)Ft

• Where 0 < α < 1.
• A higher α increases responsiveness.
• Most widely used method.

Comparison Summary

The Naïve method is the simplest. The Moving Average (MA) smooths noise. The Weighted Moving Average (WMA) is more... Continue reading "Operations Management Concepts: Forecasting, Quality, and Inventory" »

Remains: Challenging Patriarchy and Caste

With the rise of the Bharatiya Janata Party (BJP) and Hindu fundamentalism, Indian feminists criticize so-called development. Under globalization and economic success—especially in the IT sector—women and minorities are often neglected. Feminist resistance, therefore, targets more than just patriarchy. Indian society celebrates shakti (the divine feminine creative power), yet controls women through sharam (shame/modesty). A woman’s sexuality is tied to izzat (family honor), meaning women carry the responsibility for male behavior, female desire is policed, and patriarchal control is naturalized.

In The Remains of the Feast, Rukmini, a 90-year-old Brahmin widow, has lived a life shaped by:

• Gender

Processor & Memory Interface

Processor & Memory Interface: The maximum size of the memory that can be used in any computer is determined by the addressing scheme. For example, a computer that generates 16-bit addresses is capable of addressing up to 2¹⁶ = 65,536 (≈ 64K) memory locations. Machines whose instructions generate 32-bit addresses can utilize a memory that contains up to 2³² = 4,294,967,296 (≈ 4G) locations, whereas machines with 64-bit addresses can access up to 2⁶⁴ ≈ 1.84 × 10¹⁹ locations. The number of locations represents the size of the address space of the computer.

The connection between the processor and its memory consists of address, data, and control lines. The processor uses the address lines to specify the... Continue reading "Processor and Memory Interface: CPU Datapath, Registers & ALU" »

Keyword Research and Analysis

SEO keywords are the important words and phrases related to the developed website content. A list of keywords needs to be carefully chosen to optimize the search. Keyword Research and Analysis is an important part of Search Engine Optimization (SEO) as well as Search Engine Marketing. For Search Engine Marketing, one can pay for certain keywords.

Futures Markets: Margins and Hedging

The Role of Margin Payments

Margin payments exist to eliminate counterparty credit risk in futures markets. Futures contracts are marked-to-market daily and losses are settled through variation margin, while initial margin acts as collateral. This system ensures that neither party can default at maturity.

Speculation vs. Hedging

Futures can be used for speculation by taking long or short positions to profit from expected price movements. They can also be used for hedging to offset the price risk of an existing exposure. For example, an equity portfolio can be hedged by shorting stock index futures. If the market falls, portfolio losses are offset by gains on futures, and if the market rises, portfolio gains...

The Restoration and the Origins of the English Novel

Restoration and Intellectual Origins of Enlightenment

The Restoration begins in 1660 with the return of the monarchy under Charles II after the Commonwealth. It marks a reaction against Puritan austerity and censorship. England experiences political stabilization and cultural renewal.

Science and Empiricism

There was a strong development of scientific thinking based on reason and observation. The influence of empiricism suggested that knowledge comes from experience. Francis Bacon promoted the scientific method, leading to the foundation of the Royal Society, which encouraged experimentation and rational inquiry.

Philosophy and John Locke

Emphasis was placed on rationalism, skepticism, and critical... Continue reading "Restoration Literature and the Rise of the English Novel" »
