Over the past 500 years, North America has been the site of ongoing mixing of Native Americans, European settlers, and Africans (brought largely by the trans-Atlantic slave trade), shaping the early history of what became the United States. We studied the genetic ancestry of 5,269 self-described African Americans, 8,663 Latinos, and 148,789 European Americans who are 23andMe customers and show that the legacy of these historical interactions is visible in the genetic ancestry of present-day Americans. We document pervasive mixed ancestry and asymmetrical male and female ancestry contributions in all groups studied. We show that regional ancestry differences reflect historical events, such as early Spanish colonization, waves of immigration from many regions of Europe, and forced relocation of Native Americans within the US. This study sheds light on the fine-scale differences in ancestry within and across the United States and informs our understanding of the relationship between racial and ethnic identities and genetic ancestry.

Plant species continue to be introduced in North America for various purposes. If the trend continues, it is probable that some will escape cultivation and become invasive in native ecosystems. We present a retrospective analysis of several structural, life history, and biogeographical attributes of woody plants introduced in North America to determine which traits characterize species that have and have not invaded. Predictive models derived from discriminant analysis correctly classified 86.2% of the species in cross‐validation, whereas those derived from classification and regression trees classified 76% correctly. From these models we created a hierarchical predictive tree that allows the user to divide species into three categories: admit (low risk of invasiveness), deny admission (high risk of invasiveness), or delay admission for further analyses and/or monitor intensively (risk cannot adequately be assessed based on only the included attributes). We recommend that species that are highly invasive elsewhere not be allowed into the U.S. and that a more conservative introduction policy using a hierarchical predictive method be employed.

Kawoq Baldomero Cuma Chávez

Baldomero Cuma gave an invited presentation to the International LT4All UNESCO conference in Paris. He gave his presentation entirely in the Kaqchikel language. In this commentary, Baldomero discusses his beliefs about language and why he presented at the conference in his Maya language. To Baldomero, Maya language preservation has profound connections to the integral being of the Maya, and language preservation should be much more than mere academic research and information collection. As he writes, "In our homes, from the womb of our mother and at birth, we hear our identity, starting with the 'ta, ta, ta, ta' or with the 'ma, ma, ma, ma.' These are aspects that for many are insignificant, bu tfo rus, they are the foundation of our millenary heritage."

The aim of this work is to systematize a model that considers the use of audiovisual resources as a complement to the development of Historical Thinking in the classroom. For the theoretical basis, we reviewed postulates about Historical Thinking in relation to film materials. We examined references regarding the relevance of complementing History classes with audiovisual material and structured criteria to help define selection parameters. For the construction of this model, we consulted dramaturgical texts through which we projected a guide serving as training for the teacher with tools to help them understand how to break down and analyze this material, and how to find the best way to use it in favor of the session and the construction of Historical Thinking. We conclude this work by providing projections in the pursuit of continuously improving didactic-pedagogical techniques that come to the aid of our students.

The experience of Latin American countries in international investment arbitration has been both challenging and full of twists and turns. The Latin American region has not only been at the origin of the discipline, but also at the heart of the criticisms and upheavals that affect it. While denunciations of arbitration have come from all over the world, they have had a particular resonance in the region, due to the traditionally hostile attitude of the region's countries to investment arbitration. This article proposes to revisit the mosaic of resistance that has given rise to an alternative counter-hegemonic project in the region. It concludes that the resistance movements in Latin America against investment arbitration have not enjoyed clear majority support and that several countries have adopted an ambiguous position towards these movements. In the absence of a coherent regional solution, the alternative proposals supported by Latin American states are both multiple and scattered and are mostly far from the radical approach put forward by the ALBA-TCP.

This is a case study on migration management in the United States of America, according to the New Political Economy approach. Attention is paid to how Latin American immigrants are treated, given the change in public policies and their economic perception. There has been a shift from open-door immigration policies to raids and massive deportations, violating the founding principles of the United States and the key to its growth and development, since immigrants are not only a greater productive factor of work, but also bring knowledge, technologies and institutions that improve the competitiveness. Faced with this change in public powers, civil society has reacted, with a revitalization of the Sanctuary Movement. This study uses an explanatory methodology on the evolution of the academic disciplines and approaches dedicated to the research on religion-economics-migration relations, to focus its attention on the case study of the Sanctuary Movement.
