You called my name and I turned around into your chest, your heart beating fast against the shell of my ear and I laughed as you lifted me up and spun us round

“I\u27m not really sure, but I think”: Entrance stories from Chinese-Americans adopted between 1995-2005

Within families, shared narratives may be used to create and strengthen a family\u27s experiences, as well as develop their identity as a group. For families that are traditionally biological, any social and cultural assumptions about their families and about biological births as a child’s entrance into their family only affirm their validity. However, for families that do not share these master narratives, they may feel edged out of the cultural and social bounds of acceptable. In place of the common birth stories and to fulfill the gaping history of a birth story, families who have adopted will share entrance stories, narratives which adopted children are told to teach them what adoption is, what it means for them to be adopted, how they came to their family and how they fit into their families. In my research, I sought to collect entrance narratives from female Chinese American adoptees who were adopted between 1995-2005 in order to derive a grounded theory of the reoccurring themes of these narratives

Origin Story

I imagine a dark and stormy night, fat drops of rain sliding down window panels like spilled ink across a canvas. She must have been crying—my mother. In the movies, they’re always crying. She must have been alone, left behind by some mysterious lover with dark eyes too poor to buy a loaf of bread, much less feed her only daughter. She was likely wrapped in a thread-barren cloak, soaked to the bone from the rain and from her tears

The Power of Rainbow Identities

A homemade photo album served as one of my first books. Within it, the story of my adoption, always recounted to me sitting on my mother’s or my father’s lap. This is you, all the way in China! And this is Mommy and Daddy and your older sister at the airport— we had to fly fourteen hours to go and get you and bring you home! I don’t think many kids have the privilege to say that one of the first stories their parents ever told them was their own. I suppose I should have felt special and empowered. But, hearing about my adoption was normal to me and my mommy-made picture merely represents one of my first experiences with reading

Acoustofluidics 9: Modelling and applications of planar resonant devices for acoustic particle manipulation

This article introduces the design, construction and applications of planar resonant devices for particle and cell manipulation. These systems rely on the pistonic action of a piezoelectric layer to generate a one dimensional axial variation in acoustic pressure through a system of acoustically tuned layers. The resulting acoustic standing wave is dominated by planar variations in pressure causing particles to migrate to planar pressure nodes (or antinodes depending on particle and fluid properties). The consequences of lateral variations in the fields are discussed, and rules for designing resonators with high energy density within the appropriate layer for a given drive voltage presente

The cellular basis of microvessel restiction and neomuscularization in pulmonary hypertension

Pulmonary hypertension is a common and serious condition, either as a primary event or secondary to other injury. In its clinical form there is always a restrictive lesion caused by vascular cell proliferation. This narrows the lumen of vessels throughout the lung but especially ones forming the microcirculation, the smallest vessels that lie adjacently to the capillaries. In addition, contractile cells develop in segments where normally these cells are absent (neomuscularization). As these cells form elastic laminae and organize into intimal and medial layers, microvascular segments that resemble capillaries in wall structure are converted into thick-walled vessels. To analyze the cellular basis of this we have developed a model of restrictive pulmonary hypertension in the rat breathing high oxygen at normobaric pressure. Vascular changes begin within hours of injury and progress until virtually all microvessels are affected. Currently, little is known of the mediators that act as signal molecules but it is likely that ones released by inflammatory and vascular cells stimulate chemotaxis, proliferation and expression of contractile organelles, as well as secretion of the matrix proteins. Light microscopy studies and quantitative methods of analysis provide a broad understanding of the nature and extent of wall reorganization within the microvessel network. High resolution studies, including the use of immunogold techniques, are critical to identify cell phenotype during the early stage of wall changes, and, later, the type of filament proteins expressed as cells switch phenotype by acquiring contractile organelles.Biomedical Reviews 1995; 4: 47-59
