Concession Stands: How Mining Investments Incite Protest in Africa
International Organization
|August 6, 2019
Summary
Foreign investment in Africa
Area of Science:
- Political Science
- Economics
- Development Studies
Background:
- Foreign investment in African mineral resources has surged.
- Understanding the socio-political impacts of this investment is crucial for sustainable development.
Purpose of the Study:
- To investigate the relationship between commercial mining investments and the likelihood, timing, and mechanisms of social and armed conflict in Africa.
- To explore the role of commodity prices and potential explanatory factors like reporting bias, environmental harm, in-migration, inequality, and governance.
Main Methods:
- Econometric analysis of mining investments and conflict data.
- Exploration of potential conflict mechanisms using geo-spatial and survey data.
- Development of an incomplete information model to explain observed patterns.
Main Results:
- Mining investments significantly increase the probability of social conflict (protests, riots) but not armed conflict (rebel activity).
- Social conflict risk escalates with exogenous increases in world commodity prices.
- Evidence for mechanisms like reporting bias, environmental harm, in-migration, inequality, and governance is weak.
Conclusions:
- Incomplete information is a key mechanism explaining how mining, commodity prices, and transparency influence social conflict.
- Transparency can mitigate the link between commodity prices and protest.

01:17Standing Waves
5.3K
Sometimes waves do not seem to move; rather, they just vibrate in place. Unmoving waves can be seen on the surface of a glass of milk kept in a refrigerator, which is one example of standing waves. Vibrations from the refrigerator motor create waves on the milk that oscillate up and down but do not seem to move across the surface. These waves are formed or created by the superposition of two or more identical moving waves in opposite directions. The waves move through each other, with their...

01:15Standing Electromagnetic Waves
2.3K
Electromagnetic waves can be reflected; the surface of a conductor or a dielectric can act as a reflector. As electric and magnetic fields obey the superposition principle, so do electromagnetic waves. The superposition of an incident wave and a reflected electromagnetic wave produces a standing wave analogous to the standing waves created on a stretched string.

01:28Standing Waves in a Cavity
1.4K
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

01:04Modes of Standing Waves: II
1.6K
The starting point for expressing the modes of standing waves is understanding the boundary conditions that the waves must follow. The boundary conditions are derived from the physical understanding of how the standing waves are sustained, that is, how the vibrating particles of the medium behave at the boundaries imposed on them.
For a tube open at one end and closed at the other filled with air, the modes are such that there is always an antinode at the open end and a node at the closed end....

A close look at earthquakes provides evidence for the conditions appropriate for resonance, standing waves, and constructive and destructive interference. A building may vibrate for several seconds with a driving frequency matching the building's natural frequency of vibration; this produces a resonance that results in one building collapsing while the neighboring buildings do not. Often, buildings of a certain height are devastated, while other taller buildings remain intact. This...

Obedience to authority is classically demonstrated in a more famous series of social psychology experiments performed by Stanley Milgram. He was a social psychology professor at Yale who was influenced by the trial of Adolf Eichmann, a Nazi war criminal. Eichmann’s defense for the atrocities he committed was that he was “just following orders.”
