summarize the key points of the paper:Glick-Schiller, Nina, Linda Basch, and Cristina Blanc-Szanton. 1992. "Towards a Definition of Transnationalism." Annals of the New York Academy of Sciences 645(1):ix-xiv.

In their 1992 paper "Towards a Definition of Transnationalism," Glick-Schiller, Basch, and Blanc-Szanton explore the concept of transnationalism, emphasizing its significance in understanding the complexities of migration and global interconnectedness. Key points of the paper include:

**Definition of Transnationalism**: The authors define transnationalism as the processes whereby migrants establish and maintain multiple connections—social, economic, cultural, and political—across national borders.

**Beyond Traditional Migration Studies**: The paper argues that traditional migration studies often focus solely on the movements of individuals from one nation-state to another. In contrast, transnationalism recognizes the ongoing relationships that migrants have with both their home and host countries.

**Social Networks and Institutions**: The authors highlight the importance of social networks and institutions that facilitate transnational connections, such as familial ties, community organizations, and economic networks.

**Impacts on Identity and Belonging**: Transnationalism influences migrants' identities and senses of belonging, as they navigate multiple cultural contexts and redefine their relationships to both their countries of origin and their new environments.

**Political and Economic Dimensions**: The paper discusses the political and economic implications of transnationalism, including the ways that migrants can engage in political processes in both their home and host countries, as well as how their economic activities can have transnational impacts.

**Call for Further Research**: The authors call for more research to explore the nuanced and diverse experiences of transnational migrants and the implications of transnationalism for social science disciplines.

Overall, the paper lays the groundwork for understanding transnationalism as a critical framework for examining the lives and experiences of migrants in a globalized world.
