Predominant topics are politics, economics and law on a global level. The term itself can be more specifically defined as 'the contemporary and historical understanding of global societies, cultures, languages and systems of government and of the complex relationships between them that shape the world we live in'. The terms and concepts of International Studies and international relations are strongly related; however, International relations focus more directly on the relationship between countries, whereas International Studies can encompass all phenomena which are globally oriented.
 Question: is international studies the same as international relations Context: The cougar (Puma concolor), also commonly known as the puma, mountain lion, panther, or catamount, is a large felid of the subfamily Felinae native to the Americas. Its range, from the Canadian Yukon to the southern Andes of South America, is the widest of any large wild terrestrial mammal in the Western Hemisphere. An adaptable, generalist species, the cougar is found in most American habitat types. It is the biggest cat in North America, and the second-heaviest cat in the New World after the jaguar. Secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although daytime sightings do occur. The cougar is more closely related to smaller felines, including the domestic cat (subfamily Felinae), than to any species of subfamily Pantherinae, of which only the jaguar is native to the Americas.
 Question: is a cougar the same as a panther Context: One often writes G = ( U , V , E ) (\displaystyle G=(U,V,E)) to denote a bipartite graph whose partition has the parts U (\displaystyle U) and V (\displaystyle V) , with E (\displaystyle E) denoting the edges of the graph. If a bipartite graph is not connected, it may have more than one bipartition; in this case, the ( U , V , E ) (\displaystyle (U,V,E)) notation is helpful in specifying one particular bipartition that may be of importance in an application. If U = V (\displaystyle U = V ) , that is, if the two subsets have equal cardinality, then G (\displaystyle G) is called a balanced bipartite graph. If all vertices on the same side of the bipartition have the same degree, then G (\displaystyle G) is called biregular.
