Lisa Patel offers a powerful reflection on the essays in the volume, asking profound questions about the ghosts left behind, the lessons learned by students whose schools have been shuttered, and those who re-enter the new building. Patel theorizes the simultaneity of oppression and resistance; as these closings slam doors shut in the faces of poor and working class youth, we witness the small and contagious miracles by which communities rally toward self-determination, ever determined to educate their babies and students, and to retain democratic ownership over the precarious spaces we call public schools.

For adults training to be professional educators, the phrase,in loco parentis, communicates the intention that schools and educators are meant to act in the role of the parent, commonly interpreted to mean acting in accordance with what is optimal for the development of the child or young person. The limits of this relationship have been debated under legal interpretations pursuant to elements, such as protection of private property and punishing hate speech. In this article, I draw attention to the ways in which schools in the USA have acted as extensions of state designs to establish and maintain sovereignty, with schooling as a primary site of political economy. In particular, I explore the ways in which immigrant youth are positioned in schools that are meant to actin loco emporium, in the place of the empire. Drawing on policy analysis and critical race ethnography, I provide analysis that is both from above and below about immigrant youth, education, and immigration policy enforcement.

We have conducted a survey of 328 protostars in the Orion molecular clouds with the Atacama Large Millimeter/submillimeter Array at 0.87 mm at a resolution of similar to 0.'' (40au), including observations with the Very Large Array at 9 mm toward 148 protostars at a resolution of similar to 0.'' 08 (32 au) This is the largest multiwavelength survey of protostars at this resolution by an order of magnitude. We use the dust continuum emission at 0.87 and 9 mm to measure the dust disk radii and masses toward the Class 0, Class I, and flat-spectrum protostars, characterizing the evolution of these disk properties in the protostellar phase. The mean dust disk radii for the Class 0, Class I, and flat-spectrum protostars are 44.9(-3.4)(+5.8), 37.0(-3.0)(+4.9), and 28.5(-2.3)(+3.7) au, respectively, and the mean protostellar dust disk masses are 25.9(-4.0)(+7.7), 14.9(-2.2)(+3.8), 1.6(-1.9)(+3.5) M-circle plus, respectively. The decrease in dust disk masses is expected from disk evolution and accretion, but the decrease in disk radii may point to the initial conditions of star formation not leading to the systematic growth of disk radii or that radial drift is keeping the dust disk sizes small. At least 146 protostellar disks (35% of 379 detected 0.87 mm continuum sources plus 42 nondetections) have disk radii greater than 50 au in our sample. These properties are not found to vary significantly between different regions within Orion. The protostellar dust disk mass distributions are systematically larger than those of Class II disks by a factor of >4, providing evidence that the cores of giant planets may need to at least begin their formation during the protostellar phase. ; National Science Foundation (NSF): AST-1814762, AST-1716259, 1815784, 1910106 Homer L.
