What are the differences between the verbs ser and estar?
Although both verbs are translated to "to be," they are used to express different kinds of "being." The verb estar typically expresses a state of being or condition of the moment. For example: El esta callado (He is being quiet). By contrast, the verb ser typically expresses the essence of something or someone. For example: El es callado (He is quiet).
What are the main differences between Realism and Liberalism?
Realism assumes that states are self-interested entities that value security, power, and self-preservation above all else. Realist theories view states as existing in the "state of nature" where there is no international governing body looking out for everyone's best interest. As result, states must focus on surviving on their own and in creating alliances only to offset the balance of power. Conversely, Liberalism assumes that states are willing and able to cooperate with each other to create positive change. Moreover, liberal theories agree that states are interdependent with each other and with non-state actors, such as international organizations and multinational companies.
Compare and contrast the the Berlin Conference of 1884 with those of the partitioning of the Ottoman Empire at the end of World War I.
Both events took place at the height of the European neo-Imperialist era of the late 19th and early 20th centuries. During the Berlin Conference of 1884, European super powers sought to partition the African continent and divide its territory among themselves in order to gain land and have access to resources. At the end of World War I, the Ottoman Empire was weak from losing the war and from increased unrest in its conquered territories. European super powers saw this as an opportunity to do the same they did in Africa and partitioned the Ottoman Empire among themselves For the participating European countries, both the Berlin Conference and the partitioning of the Ottoman Empire not only allowed them to gain territory but also to extend their influence to Africa and the Middle East. Both of these events saw the creation of many of the modern-day African and Middle Eastern nations we have today, but also saw the beginnings of the political and ethnic unrest currently plaguing most countries in Africa and the Middle East.
