Hume’s Epistemology: Ideas, Facts, Causation, and Substance
Hume: Two Ways of Knowing
Hume distinguishes two ways of knowing: relations of ideas and matters of fact.
Relations of Ideas
This is the knowledge of logic and mathematics. These propositions are:
- Independent of facts, concerning only relations between ideas.
- Reached by reasoning alone, without experience.
- Necessarily true; their opposite implies a contradiction.
Matters of Fact
This is the knowledge of the positive sciences. These propositions:
- Report facts about the world.
- Are known from observation and
Multithreading Benefits, Synchronization, and Deadlock Prevention
Multithreading Advantages
The USO (User Space Option/User System Option – define the acronym if known) provides several multithreaded benefits. Programs using multiple threads are faster than those implemented with multiple processes because thread creation, context switching, and disposal generate less overhead.
- Threads share the same address space, enabling quick and efficient communication.
- Threads within the same process can easily share resources like file descriptors, timers, and signals.

Administrative Organs
Types and Functions
Administrative organs are units assigned functions with legal effects on third parties. Types include:
- By number of people: Single or Chartered
- By activity: Active or Advisory
- By function: Management or Control
- By territorial scope: Central or Peripheral
Scope of Authority
Authority is the relationship between public purposes and administrative power. Powers are defined by law, considering:
- Hierarchy: Static (echelon) and Dynamic (orders and conflict resolution)
- Coordination:
Principles of Criminal Law and Legal Interpretation
Principles of Criminal Law
From Aristotle to Kant, humans are considered sociable beings interacting within society. The state’s power to punish must be exercised within legal and fundamental rights, preventing a police state and protecting individual liberty.
The rule of law requires punitive power to be subject to legal boundaries and principles. Individuals are protected by criminal law, which prevents crime and limits punitive authority.

AIDS and HIV Infection
What is AIDS?
AIDS, a disease caused by HIV, manifests after infection with the human immunodeficiency virus (HIV).
- Syndrome: A group of signs and symptoms characterizing a disease.
- Immunodeficiency: The body’s inability to defend against microorganisms.
- Acquired: Unlike other immunodeficiencies, AIDS is not congenital but caused by an external factor.
Etiologic Agent: HIV
HIV is a retrovirus (an RNA virus that replicates via a DNA intermediate). It’s fragile and easily inactivated

History of Cell Biology
Robert Hooke (first to observe cells in cork), Robert Brown (discovered the cell nucleus), Purkinje (coined the term protoplasm), and Schwann and Schleiden (*Cell Theory*).
Cell Structure and Organization
Theme
Cells exhibit diverse shapes: star-shaped, elongated, cylindrical, etc.
Size
Cell size varies greatly; most are microscopic. Measurement units include microns and Angstroms.
Organization
Prokaryotic cells (bacteria): Organelles lack membrane-

Heuristic Evaluation
Jakob Nielsen’s heuristic evaluation involves experts judging an interface’s compliance with usability principles.
Process
- Recruit 3–5 usability experts.
- Individual interface inspection.
- Merge and prioritize findings.
- Report key issues and fixes.
10 Usability Heuristics
- Visibility of system status: Provide feedback (e.g., email “swoosh” sound).
- Match between system and real world: Use familiar concepts (e.g., shopping cart).
- User control and freedom: Offer undo/redo options.
- Consistency
Machine Learning Fundamentals: Data Types, Algorithms, and Clustering
Data Types
Integer: Whole numbers, without decimals.
Double: Rational numbers, i.e., with decimals.
Character: Data in text format. (“Juan”)
Logical: Values of True (TRUE) or False (FALSE)
Data Structures
- Vector: The fundamental data structure in R. It stores an ordered set of values called elements. A vector can contain any number of elements, but all elements must be of the same type.
- Factors: A special data structure where R recognizes that the stored values represent different categories of a qualitative

Philip V’s Reign (1700-1746): Centralization and Administrative Reforms
Philip V, often unable to perform his functions, delegated power to figures like Cardinal Alberoni and the Baron of Rippedá, before establishing an absolutist bureaucracy including José Patiño. His reign was briefly interrupted by his son Louis I in 1724.
Centralization
The objective was a French-style standardization and centralization:
