Origins of the Labor Movement

Collective industries created a large labor force that developed its own class consciousness and unique forms of social conflict. The origins of the movement were rooted in a society where conflict was frequent following the end of the Ancien Régime. The population suffered from food shortages and extreme exploitation.

Social Conflict and Industrialization

With the abolition of the Ancien Régime, handicrafts were replaced, and peasants were freed from guilds. However, feudal burdens and bondage were replaced by an abundant labor supply, making hiring conditions and wage levels unfavorable for workers. The new industrial economy suffered from crises characterized by growing unemployment, which fueled social conflict....

Knowledge and Perceptions in Hume's Philosophy

Knowledge consists of perceptions, which are divided into two main types:

• Impressions: Immediate acts of sensory experience. Sensation relates to the exterior world, while reflection relates to the internal world.
• Ideas: Copies of impressions, which are weaker and appear in a different temporal order.

Characteristics of Ideas

Ideas are not innate. They are not obtained through abstraction, nor are they archetypes, exemplars, universals, or ways of thinking. Imagination produces complex ideas by grouping simple impressions and ideas together.

Laws of Association of Ideas

• Similarity: Ideas are grouped by virtue of likeness or identity.
• Contiguity in Space and Time: Establishing a relation between ideas based

Cellular Unions and Plasma Membrane Specialization

Specialized regions of the plasma membrane centered in specific proteins are known as cellular unions (or cell junctions). Transmembrane unions are especially important in epithelial tissues.

Classification by Structure

• Zonulae: Completely surround the cell.
• Maculae: Spot-like unions.

Classification by Function

• Occluding Junctions: Their primary function is to close the intercellular space between cells, preventing molecules from passing between them.
• Anchoring Junctions: Connect the cytoskeleton filament of one cell to another or to the extracellular matrix, increasing resistance against strong mechanical tensions. Types include zonulae adherens, maculae adherens (desmosomes), and hemidesmosomes.

Adjetivo

Gender and Number

Adjectives can be invariable or variable. Their number is marked by the plural -s.

Grades

• Positive: the adjective expresses a quality without comparison.
• Comparative: establishes the first comparison between two elements (inferiority, equality, superiority).
• Superlative: expresses the quality in its highest degree.
  • Relative superlative: the absolute (-isimo, -errimo, super-, ultra-, requete-), with very, extremely, etc.

Position of the Adjective

Adjectives may be placed antepuesto (before the noun) or pospuesto (after the noun).

Types

• Specificative: new buildings (limits the meaning of the noun).
• Explanatory: new buildings (describes an inherent quality).

Classification of Adjectives

• By gender: variable or invariable.
• By structure:

Neodarwinism

Neodarwinism is a school of thought that emerged in the 20th century, associated with Wright, Dobzhansky, Mayr, and Weismann. Starting from Darwin's work, it held that natural selection was the main mechanism of organic change and the exclusive explanation of evolutionary processes. Its defenders were known as neodarwinists.

Punctuated Equilibrium

Punctuated equilibrium is a theory proposed by Eldredge and Gould that challenged the gradualist view of biological evolution. According to this theory, during most of the time a species exists, it remains stable or undergoes only minor changes (known as stasis). Evolutionary change occurs mainly during brief periods of rapid speciation, in which a new species arises, often from small isolated...

Pre-Evolutionary and Evolutionary Theories

Pre-Evolutionary Explanations and Fixism

The creationist theory is based on a literal interpretation of the Book of Genesis. Its basic theses were the fixed and definitive creation of all living species by God in His image and likeness. These conceptions assumed a fixist perspective, meaning the immutable character of species over time. They considered that the adaptability of individuals to the environment was solely the result or product of intelligent design. According to them, this evidenced the existence of a creator behind every life design.

In the eighteenth century, fixist creationism had defenders such as Carolus Linnaeus and Georges Cuvier. They maintained that adaptation to the medium was the...

Cell Membrane

1. Membrane: The cell membrane is a thin lamina enveloping the whole cell. It separates the internal content of the cell from the external environment and controls the passage of substances. It also surrounds organelles such as chloroplasts and vacuoles.

Composition and Structure

• Lipids: 50%
• Proteins: 40%
• Carbohydrates: 10%

The structure is modeled as a "fluid mosaic model".

Lipids

• Phospholipids: form a lipid bilayer. They have mobility. The head is polar (hydrophilic) and the two tails are non-polar (hydrophobic) fatty acid chains.
• Cholesterol: a steroid found in the membrane. It is important in the hydrophobic area. It increases fluidity, resistance and stability.

Only in animal cells.

Proteins

• Transmembrane proteins: cross the membrane

Aristotelian Metaphysics: Substance and Accidents

There are different kinds of objects that can be presented. The characteristics that can be attributed to a substance exist in an independent way and are called accidents. Aristotle called accidental categories those characteristics that can be attributed to a substance. They include quantity, quality, relation, place, time, possession, action, situation, and passion. Concrete disciplines are contained in one concrete category.

Matter and Form

A substance is a compound of matter and form. Matter is that which receives a form and is the principle of individuation. Form is the organization or disposition of matter; it is the essence of the object. Different individuals can share the same form, which...

Periods of Islamic Art

Caliphate Period

During this era, architecture saw the widespread use of the horseshoe arch, characterized by increased height. Architects adopted the Corinthian capital from Roman art, while arch segments were aligned horizontally toward the "kidneys" of the arch, a style known as the enjarjazo arch. By the mid-10th century, the caliphal arch, lobed arch, and the Alfiz were introduced. Vaulting techniques were common, excluding the dome. Decoration focused primarily on simple geometric patterns and plant motifs. The most characteristic architectural construction of this period is the Great Mosque.

Almohad Period

Following the disruption of the Caliphate into various Taifa kingdoms, the Almoravids arrived to unify the territories....

Architecture in the Twentieth Century

The first third of the twentieth century saw Bauhaus, Modernism and industrial architecture transform cathedrals, factories and cities. Architects used new materials such as concrete, steel and glass alongside classic materials such as wood and stone, and prefabricated elements allowed rapid construction and simplified structural calculation.

Characteristics: The architecture of the period responded to the needs of industry, transport, schools, hospitals, administration and culture, rejecting ornament and favoring clean geometric lines, horizontals and verticals.
