When are accents used in Spanish?
Accents are used to emphasize parts of words where the stress does not usually land. Spanish word stress usually falls into two categories: when a word ends in a vowel, n or s, the stress is on the second to last syllable, and when the word ends in a consonant that is not s or n, the stress is on the last syllable. Therefore, when a word breaks one of these rules, an accent is used to show where the stress falls. "También" is an example of such a rule breaker; normally the emphasis would be on the first syllable. Accents can also be used to differentiate words with the same spelling, even when they are pronounced the same way. For example, el and él have the same pronunciation, but different meanings. Accents are also used to differentiate question words from their non-inquisitive usage, such as quién and quien.
What is the circle of fifths, and how does is pertain to music theory?
The circle of fifths represent the 12 tones of the chromatic scale, as well as their corresponding major and minor key signatures. Each pitch is five whole steps away from its neighbor, and the number of sharps in each key signature ascends with each ascending pitch. Halfway through the scale, at F#/Gb major, the key signatures switch from sharps to flats, and the number of flats descend as one continues through the chromatic scale. It can be used to identify the major or minor key of any given piece of music by looking at the number of flats or sharps in the key signature.
What are the prevailing theories of international relations, and how do they explain the world around us?
The main theories of international relations are realism and liberalism. Realism states that countries will always act in their own national self-interest, and tend to work with other countries on common goals only if it offers them a significant advantage or benefit. Realists tend to point to centuries of war for territorial or economic gain as evidence for their theory. Liberalism is the opposing notion that countries will tend to work together toward common goals to ensure economic growth for all parties, and that enhanced international interdependence has led to a more peaceful and prosperous world. Liberals tend to point to the post-World War II period of economic growth and relative peace as evidence for their theory. These two theories are not the only ones proposed to explain relations between different countries; constructivism, Marxism, and feminist theories are also used to explain the actions of countries throughout history. However, most of these theories can fit into some aspect of either rational or liberal theory.
