examined variables that influence the model such as: participation in a college course with global components, perception of one's global knowledge, college professors' attitudes toward global citizenship, belief in an intentional worlds view of culture, participation in a fan group that promotes the identity, use of global citizen related words when describing one's values, possible self as a global citizen, religiosity and religious orientation, threat to one's nation, interdependent self-construal prime, perception of the university environment, and social media usage. In 2019, a review of all studies of the psychology of global human identification and citizenship through 2018 was published. Aspects Geography, sovereignty, and citizenship At the same time that globalization is reducing the importance of nation-states, the idea of global citizenship may require a redefinition of ties between civic engagement and geography. Face-to-face town hall meetings seem increasingly supplanted by electronic "town halls" not limited by space and time. Absentee ballots opened the way for expatriates to vote while living in another country; the Internet may carry this several steps further. Another interpretation given by several scholars of the changing configurations of citizenship due to globalization is the possibility that citizenship becomes a changed institution; even if situated within territorial boundaries that are national, if the meaning of the national itself has changed, then the meaning of being a citizen of that nation changes. Human rights The lack of a universally recognized world body can put the initiative upon global citizens themselves to create rights and obligations. Rights and obligations as they arose at the formation of nation-states (e.g. the right to vote and obligation to serve in time of war) are being expanded. Thus, new concepts that accord certain "human rights" which arose in the 20th century are increasingly being universalized across nations and governments. This is the result of many factors, including the Universal Declaration of Human Rights by the United Nations in 1948, the aftermath of World War II and the Holocaust and growing sentiments towards legitimizing marginalized peoples (e.g., pre-industrialized peoples found in the jungles of Brazil and Borneo). Couple this with growing awareness of our impact on the environment, and there is the rising feeling that citizen rights may extend to include the right to dignity and self-determination. If national citizenship does not foster these new rights, then global citizenship may seem more accessible. Global citizenship advocates may confer specific rights and obligations of
