Pride and Prejudice: Appearance vs Reality
By Paula Alvarez
The Theme of Appearance vs Reality
In Jane Austen’s Pride and Prejudice, the theme of appearance versus reality is recurrent. Austen wants to prove to us that often one’s appearance hides one’s true character. This theme is clearly evident in the case of Mr. Darcy and Mr. Wickham and how they appear to Elizabeth Bennet.
Elizabeth’s Misguided Conclusions
From her first impressions of both Mr. Darcy and Mr. Wickham, Elizabeth

Hybrid Hash-Join: Conceptual Explanation
Hybrid Hash-Join is an improved version of the standard Hash-Join algorithm that reduces disk I/O by using memory more efficiently during the join operation. It is particularly useful when:
- The build relation is larger than memory.
- Memory is still large enough to hold one or more partitions fully.
Why Use Hybrid Hash-Join?
In a normal Hash-Join:
- All partitions of the build relation are written to disk first.
- They are then read again for probing.

Core Principles of Quantum Mechanics
The No-Cloning Theorem
The no-cloning theorem states that it is impossible to create an exact copy of an arbitrary unknown quantum state. This is because quantum mechanics is linear and unitary; any operation that clones one state would necessarily distort another. Only orthogonal states (like |0⟩ and |1⟩) can be perfectly distinguished and copied.
The Copenhagen Interpretation
According to the Copenhagen interpretation, the wave function represents the probability

Meaning and Definition of Arbitration
Definition: Arbitration is a private, consensual, party-driven method of dispute resolution where two or more parties agree to settle a dispute with the assistance of an arbitrator. Source of Authority: Unlike litigation, which derives authority from the State, arbitration’s legitimacy flows from the parties’ agreement. In Collins v Collins (1858) and as approved in Malaysian jurisprudence, arbitration is a ‘reference to the decision of one or more persons…

Predict P(churn = 1) via logit link → ln(p/(1-p)) = β0 + βx
| Metric | Meaning | Trade-off / Exam Tip |
|---|---|---|
| Precision = TP/(TP+FP) | How accurate are my churn flags? | Higher precision → fewer false alarms |
| Recall = TP/(TP+FN) | How many real churners are caught? | Higher recall → catch more churners |

| ROC Curve | TPR (Recall) vs FPR (1 − Specificity) | Curves that bow toward the |
Fundamentals of DBMS and Database Concepts
Data, Information, Knowledge
Data – a fact that can be recorded or stored, e.g., person name, age, gender, weight, etc. Information – when data is processed, organized, structured, or presented in a given context so as to make it useful, it is called information. Knowledge – it is the appropriate collection of information.
DBMS (Database Management System)
DBMS = Database + Set of programs.
- Database – a collection of logically related data; e.g., books database in a library, student database in a university.

Spanish Liberalism: Bourbon Dynasty to First Republic
Introduction: The Bourbons, a New Dynasty in Spain
The Habsburg dynasty ended in 1700 with the death of Charles II, who had appointed as his heir the French prince Philip of Bourbon, while Archduke Charles of Habsburg (Austria) claimed his rights to the throne. This led to an international conflict as the balance of power was disturbed, and within Spain, territories supported different pretenders. This resulted in the War of the Spanish Succession (1701–1714).
Philip V of Bourbon won the war. He

Fundamental Laws and Conservation Principles
- Newton’s First Law: An object stays in uniform motion unless a net force acts (if net force = 0, motion remains unchanged).
- Newton’s Second Law: Acceleration is proportional to net force and inversely proportional to mass.
- Newton’s Third Law: Forces come in equal and opposite pairs (action and reaction).
- Conservation of Energy: Total mechanical energy remains constant if no non-conservative forces act.
- Conservation of Momentum: Total momentum stays constant
