THE DUST BOWL

Globalisation

Globalisation consists of the growing integration of national economies in a worldwide market economy.

Causes of globalisation

• Progress of telecommunications: provides information in real time and permits contact between people anywhere on the planet.
• Improvement of transport: facilitates the transfer of goods and people around the world.
• Widespread adoption of capitalism and neoliberal ideals: has helped economic relations throughout the world.

External Structure of the Earth

• Lithosphere: It includes the crust and the upper mantle. It is the solid part of the Earth.
• Hydrosphere: It includes all the waters on Earth.
• Atmosphere: Gaseous layer that surrounds the Earth.
  • Troposphere (0–10 km): Where weather phenomena take place.
  • Stratosphere

The Fibre Placement Process

Automatically places multiple individual prepreg tows onto a mandrel at high speed, using a numerically controlled, articulating robotic placement head to dispense, clamp, cut and restart as many as 32 tows simultaneously. Machines are available with dual mandrel stations to increase productivity.

Advantages of fibre placement include:

• Processing speed
• Reduced material scrap
• Labour costs
• Parts consolidation
• Improved part-to-part uniformity

Often used to produce large thermoset parts with complex shapes.

Early European Expeditions: Portugal & Castile

• The monarchs of the Kingdoms of Portugal and Castile began to finance exploratory voyages.
• The Kingdom of Portugal sought to reach India via an easterly route, sailing around the coast of Africa to the Indian Ocean.
• These efforts continued until Bartolomeu Dias discovered the Cape of Good Hope in 1487. Later, an expedition led by Vasco da Gama followed this route, reaching Calcutta, India, in 1498.
• The Kingdom of Castile attempted to reach India via a western route, crossing the Atlantic Ocean. An expedition led by Christopher Columbus discovered a new continent, America, on October 12, 1492.

Christopher Columbus and the Discovery of America

• Christopher Columbus was a sailor, likely from Genoa, who

More Efficient Overland Transport

Overland transport consists of road and rail transport.

Road Transport

Road transport has grown significantly since the mid-20th century. It is the most widely used means of transport over short and medium distances for the movement of people (cars, buses) and goods (lorries, vans).

Advantages

• Convenience
• Time flexibility

Disadvantages

• High cost of infrastructure
• High accident rate
• Air and noise pollution
• High volumes of traffic, especially in cities

Rail Transport

Rail transport was the main means of transport in the 19th century. In the 20th century, it began to decline due to competition from road and air transport. However, in high-income countries, rail transport is becoming popular again due to high-speed trains.... Continue reading "Efficient Overland and Maritime Transport Systems Explained" »

There are three types of reefs:

• Fringing Reef – Coral platforms grow out to sea attached to the mainland.
• Barrier

3. Recent immigration (1970–present): Large numbers of people have come from Mexico, China, Korea, India, and the Philippines, as well as other parts of Latin America and Asia.

7. 3 reasons why current immigration is different

First, a significant number of today’s immigrants have entered thecountry illegally, and thus their position is insecure.

Second, today’s immigrants are largely non-white. Race has formed a principal line of fragmentation within American society, and, as such, it threads its way insistently throughout the story of immigration. Race separated the experiences of voluntary immigrants in the distant past, for such minority immigrant peoples as the... Continue reading "Legal monism" »

Economic Crisis and Recovery in 17th Century Europe

Causes of the 17th Century Agricultural Crisis

In the 17th century, agriculture was the primary economic activity. However, it suffered a significant crisis due to several factors:

• Wars: Many areas were plundered, leading to a decrease in the rural workforce.
• Plagues and Epidemics: Frequent outbreaks significantly reduced the agricultural workforce.
• Urban Migration: Farmers migrated to cities to avoid taxes they could no longer afford to pay.
• Outdated Techniques: Agricultural productivity remained low due to obsolete technology.
• Bad Harvests: Adverse weather conditions led to years of poor crop yields.
• Subsistence Crisis: These factors resulted in lower productivity and a sharp increase in prices.

A greater biomass;

Higher levels of species diversity;

Better soil structure and greater water retention;

Lower pH;

Plant species will be taller and longer living;

Greater community complexity and stability/equilibrium;

Greater habitat diversity;

B Award [3-4 max] for human threats, [3-4 max] for natural threats

and [2-4 max] the consequences.

e.g. Great Barrier Reef off the coast of Queensland, Australia

Human threats:

• Tourism; coral is very fragile and easily damaged by divers’ fins, touching coral, or breaking bits off for souvenirs;
• Overfishing can disrupt the balance of species in the food chain;
• Inadvertent damage from anchors and pollution from boats;
• Run-off of fertilizers from sugar plantations on the coast;
• Sewage and pollution from coastal settlements

China: Population 1.3 billion growing rapidly - 1 child policy used in the past

Most population in middle/middle-high income. Therefore spend a lot on luxury goods - more than any other country. Manufacturing hub Fashion industry - open to overseas brands, willing to spend a lot (not price sensitive) GDP growing fast, huge economy, dynamic & successful TRADE - surpassed US as a trading nation, rely heavily on emerging markets such as Brazil for exports but these EM cannot compete with their huge success and dominance. E-commerce industry is huge - no Facebook Whatsapp or Google, they use their own, WeChat has 900 million users. Use phones for everything. “Belt Road Initiative” - extend trade routes & integrate the economy. Opportunities... Continue reading "China: Opportunities and Strategies for Doing Business" »
