Bayesian additive regression trees (BART) is a fully Bayesian approach to modeling with ensembles of trees. BART can uncover complex regression functions with high-dimensional regressors in a fairly automatic way and provide Bayesian quantification of the uncertainty through the posterior. However, BART assumes independent and identical distributed (i.i.d) normal errors. This strong parametric assumption can lead to misleading inference and uncertainty quantification. In this chapter we use the classic Dirichlet process mixture (DPM) mechanism to nonparametrically model the error distribution. A key strength of BART is that default prior settings work reasonably well in a variety of problems. The challenge in extending BART is to choose the parameters of the DPM so that the strengths of the standard BART approach is not lost when the errors are close to normal, but the DPM has the ability to adapt to non-normal errors.

As the bell rang, sounding the beginning of the school day, Ji-Sook (Elizabeth) entered the classroom, her pink tweed coat and mittens still frosty from the snow outside. This was Ji-Sook's second year of school in Canada and her first year at Streamside School. She really liked it here and loved her teacher, Ms. Song Lee. Ms. Lee was always sharing stories with the class about her experiences growing up in another country as well as her arrival to Canada and growing up in small towns where Ms. Lee was often the only Chinese person in her school. Listening to Ms. Lee's stories helped Ji-Sook think about Korea and her family there.Removing her coat, Ji-Sook moved quickly to hang it up, her dark curly bobbed hair bouncing as she skipped. Her newly permed hair felt different, but she liked the way it looked. Today Ji-Sook was wearing a favourite outfit, a knitted sweater with a matching plaid skirt. After hanging up her coat, Ji-Sook turned to face the class and noticed that along with her teacher, Ms. Lee, was Ms. Mitton and Ms. Simmee. Ji-Sook was surprised to see Ms. Mitton and Ms. Simmee at school on a Tuesday morning for they usually came in the afternoon. She greeted them happily and took another close look around the room for Ms. Jean. Ji-Sook asked Ms. Mitton where Ms. Jean was; Ms. Mitton smiled and reminded Ji-Sook that Ms. Jean would be coming Wednesday afternoon. Ji-Sook remembered to ask if Ms. Mitton would read with her during shared reading time.Ji-Sook knew it was going to be a very special day. Yesterday afternoon Ms. Lee had reminded the children that in the morning they were to begin a wonderful art project and create their own Starry Night paintings. Quickly Ji-Sook removed the book about Van Gogh, which discussed his Starry Night painting, from her backpack and, before everyone was seated, showed Ms. Lee and Ms. Simmee her book from home. The night before, she and her mother had spent time reading the book aloud. Ji-Sook felt it was much easier to read aloud in Korean than in English. Today's art lesson was out of the ordinary for she loved being able to bring things from home that fit with what they were learning in the classroom. And today was very special.Before going to her desk, Ji-Sook retrieved the poetry book that had a picture of a boy peering over the end of a sidewalk,¹ Ji-Sook hurried to her desk and sat down and waited for Ms. Mitton to join her for reading. Seated with three of her classmates at a table composed of 4 desks, she smiled at Nathan, Grace, and Dana. There was so much to be excited about as she knew that after school today there were parent teacher interviews. Ji-Sook knew her mother was not working at the deli shop and was going to come to the interviews with their neighbour who would translate for her. Ji-Sook so loved it when her mother came to school. Once Ms. Mitton arrived, she and Ji-Sook spent a few minutes reading aloud together before Ms. Mitton went to join Ji-Sook's friend, Hailey, who had also asked Ms. Mitton to read with her. Ji-Sook continued to read and look at the drawings in this wonderful book.Adjusting her headset and microphone, Ms. Lee asked Ella, the class's ‘star-of-the-week’, to tap on the desks of each group to indicate that they were to come to the sharing area. Ji-Sook waited excitedly for Ella to tap her group's desks and then she hurriedly joined Grace, Nathan, Dana, and the rest of her classmates on the foam mats by the picture window. Ms. Lee began the art lesson by showing examples of Starry Night paintings completed by the students she had taught last year. Ms. Lee then shared the rubric with which Ji-Sook and her friends could assess their paintings. Ji-Sook knew that Ms. Lee worked with Mrs. D, the other Grade 3 teacher, and that students in both classes would be making the paintings. Once Ms. Lee finished explaining the steps of their art lesson, she asked Ji-Sook if she would like to come and share the book she brought from home.Sitting at the front of the class in Ms. Lee's chair and wearing her microphone, Ji-Sook read aloud from the book. The book was in Korean and Ji-Sook scanned each page quickly before explaining to the class bits and pieces about Van Gogh's life. Ji-Sook, reading from her book, explained that Van Gogh cut off his ear because he couldn’t draw his own portrait properly. Ms. Lee later returned to this detail and asked about how this piece of information in Ji-Sook's book was different from what they had previously read about the artist. The children remembered that Van Gogh cut off his ear for a woman he loved and had offered his ear as a gift to her. Ms. Lee asked the class to think about these two different pieces of information. Following this question Ms. Lee asked what the children might do to ensure the information they found was accurate. Logan suggested that reading many sources would help.Ms. Lee then drew the children's attention to Ji-Sook and said that as Ji-Sook read she was doing two things at the same time. She asked the class what they thought she was doing. Mya suggested Ji-Sook was reading and then talking. Picking up on Mya's point, Ms. Lee emphasized that Ji-Sook was reading in Korean first and then translating what she read into English. Ms. Lee asked Ji-Sook if she would like to read aloud in Korean. Ji-Sook momentarily hesitated but responded with a smile when her classmates encouraged her. Ji-Sook read one page aloud. She read quickly and the rhythm of how she read aloud in Korean sounded very different from her reading skills in English.Paper and crayons were distributed. Ji-Sook, Grace, Nathan, and Dana were quiet as they began their Starry Night paintings. Looking over the rubric that Ms. Lee had explained, Ji-Sook understood the first step today was to plan the sky and landscape of her painting. She knew the sky was to be about 2/3 of the paper and that everything she drew was to be in small dashes. It was important for the sky of her painting to look like it was moving. Ji-Sook was aware of Ms. Lee moving about the classroom, helping her classmates check, whether or not, the sky in their paintings was approximately the right size. As everyone worked, Ji-Sook heard Ms. Lee remind the class to press hard with their crayons so that the paint would have something to cling to as it dried. Taking Ms. Lee's advice seriously, Ji-Sook pressed firmly each time her crayons touched the paper, and soon her right arm grew tired. Ji-Sook now had a better idea about what Ms. Lee meant by this art project taking a long time to complete. (Interim research text based on field notes,² November 21, 2006)

Past research on the immigrant health paradox suggests that children with immigrant parents may have a health advantage over those with US-born parents, especially if the parent is a recent immigrant. Other research emphasizes the social and economic challenges children with immigrant parents face, in part due to disadvantaged social class and racial/ethnic positions. Underlying physiological changes due to chronic stress exposures among children in immigrant families is one potential health disadvantage that may not yet be apparent in traditional health measures. To explore these biological disparities during childhood, I use national biomarker and survey data from the National Health and Nutrition Survey (NHANES) (N = 11,866) to evaluate parent nativity and educational status associations with low-grade inflammation, indicated by C-reactive protein (CRP), in children ages 2–15 years. I find that children with an immigrant parent, and particularly a low-educated immigrant parent, have higher CRP, net of birth, body mass index (BMI) and other factors, than children with a US-born parent with either a low or higher education. Comparing children with low-educated parents, those with a foreign-born parent have higher predicted CRP. The findings from this study provide new evidence that children living in immigrant families in the US may be facing higher levels of chronic stress exposure, as indicated by the increased risk of low-grade inflammation, than those with US-born parents. The physiological changes related to increased risk of inflammation, could set children in immigrant families on pathways toward mental and physical health problems later in the life course.

The children returned and Ms. Lee had them go to their desks. There was so much excitement in the air … . Ms. Lee has rearranged the desks again and I like how there are such frequent shifts in seating. Ms. Lee spoke of their photographs and their collages. She then said I would give the guiding question for their work on the citizenship education project today in their small sustained response groups. I fumbled badly and said something about who they are and how they belong. Ms. Lee wrote it on the board. As Ms. Lee continued to speak, I went and changed the words to “Who I am and how I belong.” Ms. Lee spoke to the children of how they were going to start putting their photos on their poster boards and to think about how their photographs were representations of who they were and where they belonged. No glue or scissors at this point. She also showed them the paper where she wanted them to write about their photographs.The children got their individual pieces of bristol board for their collages and Ms. Lee said they might want to choose a spot on the floor as they did this work. They were intent and focused on their own photographs but were also sharing with their neighbours. At one point, I commented to Ms. Lee, Simmee, and Jennifer about how impressed I was with their intentness. I spent some time with Logan who had some magnificent photographs … he has an eye for the aesthetic. I pointed out to him how much I liked the photographs. I also spent some time with Taylor who had three photographs of clothes: one Chinese outfit, one Korean outfit, and a long white dress that she said she did not know what it was. I asked if it was a christening dress and she said she thought so, that her mom had taken the photograph. She also had a close up of a Canadian flag. I spent some time with Sophie who had rejected some of her photographs as not interesting. When I pointed out what I saw as interesting things in her photographs, she started to see them more positively. I asked a few children what they planned to put in the centre of their collages. I realized, even as I asked that question, that I was privileging the centre photograph. Liam had his dad's photo clearly in the centre. He was busily writing words. He said he wasn't sure what to write about his dad but then wrote something about family being important. (Field notes, April 2, 2007)

Victim narratives consistent with anti-trafficking and anti-prostitution rhetoric leave little room for understanding agential labor in the sex industry, which profoundly impacts sex workers’ experiences in other domains. One such domain – academia – is often understood as antithetical to the “body work” of sex work. It is, after all, the domain of the mind. Drawing from my experiences as an undergraduate and graduate student as well as from my work as a sex worker, I use auto-ethnography to demonstrate the lasting impact of (1) mind/body dualisms, (2) the virgin/whore dichotomy, and (3) narratives of sexual danger on perceptions of legitimation and status for sex workers in academia. I also discuss implications for broader social concerns like legal policy.

This chapter examines megaproject design and planning in two “shrinking cities” – Philadelphia, PA and Detroit, MI – and concludes that megaproject “metastasis,” or repeated expansions into surrounding urban fabrics, is promoting the reduction of downtown into a series of self-contained enclaves. While political coalitions are constructing megaprojects, or large public works and/or single buildings, in cities around the world, in the United States, single-building megaprojects motivated by “growth coalitions” of public and private development actors have proliferated in downtowns since 1990. The urban design impacts of these megaprojects on the surrounding urban fabric have been little studied. Data on the institutional history, physical expansion, and relationship of the megaprojects to the urban fabric is combined with a qualitative analysis of megaproject theory and its application to the American condition, as well as to the political economy of development in American shrinking cities. The chapter concludes that megaprojects such as convention centers and casinos tend to expand inexorably once they are introduced into the American downtown. This metastasis results in the destruction of existing older buildings and street networks, the consolidation of street blocks into ever-larger superblocks, and the eventual physical restructuring of downtowns into enclaves of older fabric amidst clusters of megaproject superblocks. Applying Jacobs’ (1992) theory of “moral hybrids” between “commerce and politics” to megaproject metastasis, the chapter argues that while megaprojects may be inevitable in American downtowns, they should be sited away from active, small-scale urban fabrics to reduce the negative impacts of future metastases. The chapter takes a design-oriented perspective on a phenomenon that is almost always understood from a political economy perspective alone. Megaprojects are significant physical entities, and the chapter clarifies their physical impacts on the urban fabric while indicating urban design policy directions to reduce these impacts in future.

Our awakening to the curriculum being made by children and families in home and community places grows out of a theoretical background that informs our current inquiry into the tensions experienced by children, families, and teachers as they compose diverse lives on school landscapes, contexts increasingly structured by achievement testing. Our understanding of curriculum is grounded in Clandinin and Connelly's (Clandinin, 1986; Connelly & Clandinin, 1988) earlier attention to curriculum making as the expression of a teacher's personal practical knowledge. They described this knowledge as “that body of convictions and meanings, conscious or unconscious, that have arisen from experience (intimate, social, and traditional) and that are expressed in a person's practices” (Clandinin & Connelly, 1995, p. 7). Dewey's (1938) notions of continuity, situation, and experience, shaped Clandinin and Connelly's (1992) understanding of the “teacher not so much as a maker of curriculum but as a part of it and to imagine a place for contexts, culture (Dewey's notion of interaction), and temporality (both past and future contained in Dewey's notion of continuity)” (p. 365). By bringing together their understandings of teachers’ knowledge as personal practical knowledge with Dewey's notion of experience and Schwab's (1969) four curriculum commonplaces – teacher, learner, subject matter, and milieu – Clandinin and Connelly (1992) suggested that curriculumbe viewed as an account of teachers’ and children's lives together in schools and classrooms … .[In this view of curriculum making] the teacher is seen as an integral part of the curricular process … in which teacher, learners, subject matter, and milieu are in dynamic interaction.

The aim of this book is to understand the causes and consequences of new scales and forms of territorial and spatial restructuring in a context of accelerated globalization by focusing on a diverse array of urban megaproject developments that, in various forms and with various objectives, are transforming the global urban landscape at the outset of the 21st century. The contributions to this volume explore the architectural design, planning, management, financing, and impact of urban megaprojects, as well as the social actors and innovations driving them. The contributions also articulate the various socioeconomic, political, and cultural causes and consequences of UMP development, thus providing a context to understand the reconfiguration of urban spaces in the new millennium.
