Understanding Key Development Indicators

HDI (Human Development Index)

The Human Development Index (HDI) is a summary measure of average achievement in key dimensions of human development: a long and healthy life, being knowledgeable, and having a decent standard of living. It was created to emphasize that people and their capabilities should be the ultimate criteria for assessing a country's development, not economic growth alone.

MPI (Multidimensional Poverty Index)

The Multidimensional Poverty Index (MPI) is a summary measure of average achievement in key dimensions of human development: health, education, and a decent standard of living. This index replaced HDI in some contexts. It is used instead of Gross National Income (GNI) because GNI... Continue reading "Understanding Key Development Indicators: HDI, MPI, GPI & More" »

First Period of Francoism (1939-1959)

Political Isolation and Repression

• Politics: During the first years (until 1945), there was a strong relationship with the Axis powers: Italy and Germany.
• After WWII, Spain was isolated. The UN declared Spain a totalitarian regime.
• There was only one political party: Falange Española y de las JONS.
• The era was marked by strong repression.
• Opposition remained hidden in the mountains, known as the Maquis.

Economic Autarchy and the Black Market

• Economy: The system of Autarchy meant Spain was isolated economically, which meant that it could not export or import any products.
• The primary sector was the most important. Except for Catalonia and the Basque Country, other regions earned their living through agriculture,

Essential Scientific Vocabulary

• Nitrogen Fixation: Any process that causes nitrogen to combine with other elements to form compounds such as ammonia, nitrates, and nitrites.
• Neutralization: The process of adding an acid and a base together to achieve a neutral pH.
• Macronutrients: Nutrients that we need in larger quantities to provide us with energy.
• Micronutrients: Vitamins and minerals needed by the body. A deficiency or surplus of them can cause severe health issues.
• Carbohydrates: Sugar molecules. Along with proteins and fats, carbohydrates are one of three main nutrients found in foods and drinks.
• Lipid: Organic fats that are insoluble in water.
• Osmosis: The movement of molecules through a selectively permeable membrane.
• Hydrolysis: A chemical

Origin of Life Hypotheses

The Oparin-Haldane hypothesis suggests that life arose gradually from inorganic molecules, with "building blocks" like amino acids forming first and then combining to make complex polymers.

The primitive atmosphere was reducing, containing water vapor and ammonia.

Both Oparin and Haldane proposed that the first life forms were heterotrophs.

Oparin's Work with Coacervates

Oparin's work with coacervates confirmed that enzymes fundamental for the biochemical reactions of metabolism functioned more efficiently when contained within membrane-bound spheres than when free in an aqueous solution.

Haldane's Primordial Soup Idea

Haldane's ideas about the origin of life were very similar to Oparin's. Haldane proposed that the primordial... Continue reading "Origin of Life: Oparin-Haldane & Miller-Urey" »

Global Impact of 19th Century Imperialism

Imperialism's Effects on Metropoles and Colonies

The consequences of Imperialism differed significantly for the metropoles (colonizing powers) and the dominated nations (colonies).

Positive Outcomes for Imperial Powers (Metropoles)

Colonialism was generally positive for the metropoles. It provided:

• Political Power: Increased global influence and prestige.
• Economic Wealth: Access to raw materials and new markets for manufactured goods.
• Social Stability: Greater social peace domestically.
• Knowledge: Exposure to and knowledge of other civilizations.

However, this expansion also intensified international political and economic confrontations that would ultimately lead to World War I.

Negative Consequences for Colonized
