LPC_GPIO2-The Rise of the Nazi Party: Social and Political Factors
Social Divisions and Class Conflict
One of the strongest divisions was class conflict between workers, the middle class, and elites. Industrial workers often supported socialist or communist parties, while the middle and upper classes feared revolution. After the Russian Revolution of 1917, many Germans were terrified that communism would spread to Germany. Hitler exploited this fear by presenting the Nazis as the main force capable of stopping Bolshevism. This gained him support from businessmen,

Module 6: Romantic Love and Social Dynamics
Key Concepts in Intimacy
- Individualistic: The needs of the individual outweigh the needs of the collective.
- Collectivistic: The needs of the collectivity are perceived as more important than the individual’s needs (e.g., historical Igbo marriage selection).
- Conjugality: A personal relationship between husband and wife; increasing emphasis on the marital bond.
- Calling: A courtship practice where men visit the home of a potential love interest.
- Face-to-Face: Women’
Sociology of Gender: Intimacy, Bodies, and Violence
Module 6: Intimacy and Social Structures
Romantic and Social Patterns
Romantic love: Intense attraction; modern ideal focused on individual choice. Sociability: Social interaction for enjoyment without instrumental goals. Calling: Men visiting women’s homes for courtship. Going steady: Exclusive long-term dating. Hookups: Casual, often one-time sexual encounters. Friends with benefits: Sex within a non-romantic friendship.

CIRCADIAN RHYTHMS
3 main properties: 1- 24h period. 2- Endogenous (rhythmic responses continue even in absence of stimulation) 3- Entrainable (rhythms can be reset/adjusted by exposure to external stimuli)
Study: rat has access to running wheel -> turns of wheel recorded on chart recorder, plots each wheel rotation as tick on chart -> each line represents one day’s activity -> activity plotted for month under no light 6am-6pm, rat shown to be active during dark hours of day-night cycle

The Role and Importance of Family
Family is the oldest and most important social institution. It is the basic unit of society and plays a vital role in the development of individuals and society. Every person is born into a family and spends most of their early life within it. The family provides food, shelter, protection, love, emotional support, and education. It also helps in developing personality, behavior, moral values, and social skills.

Data Warehouse Fundamentals and Architecture
Difference Between Data Warehouse and Data Mart
| Basis | Data Warehouse | Data Mart |
|---|---|---|
| Scope | Entire organization | Specific department |
| Size | Large | Small |
| Data | All business data | Subject-specific data |
| Users | Whole organization | Department users |
| Cost | High | Low |
| Time | More implementation time | Less implementation time |
| Complexity | Complex | Simple |
Key Takeaways
- Data Warehouse: Stores organization-wide data.
- Data Mart: Stores department-specific data.
👉 Warehouse = Whole company
👉 Mart = One department

Express Framework Fundamentals
The Node.js web framework provides a structured pipeline from top to bottom:
- Routing system
- Middleware pipeline
- Response utilities
- Template integration (Pug, etc.)
The standard flow follows: Request → Middleware → Route → Response.
Middleware Pipeline
Middleware functions run before the final response. The function signature is (req, res, next). These functions can:
- Modify the req or res objects.
- Stop the request using
res.send(). - Pass control using
next().
Note: If neither
