Howells, Dickinson, Lewis: An exercise in reading the interracial canon

Howells, Dickinson, Lewis: An Exercise in Reading the Interracial Canon has two purposes. First, it offers detailed readings of three American novels: An Imperative Duty by William Dean Howells (1891), What Answer? by Anna Dickinson (1868), and Kingsblood Royal by Sinclair Lewis (1947). These readings are accomplished within the context of the interracial canon , a set of writings dealing with the expression of various aspects of interracial relationships. The interracial canon, as well as its specialized vocabulary and unique theoretical outlook, is roughly sketched in an introduction and several appendices

Clinical Experiences and Mediational Activities in Urban Teacher Preparation: Learning and Critical Consciousness

In a longitudinal design experiment conducted within an urban teacher preparation program, we employed ethnographic and auto-ethnographic methods to investigate the following research questions: 1) In what ways do clinical experiences (CEs) support prospective teachersΓÇÖ (PTs) development of knowledge, skills, and dispositions necessary for urban teaching? 2) How is it determined that adjustments need to be made to the design and facilitation of CEs, and what did these adjustments yield in terms of student learning outcomes? The program centers and leverages CEs in order for PTs to connect theory and practice, particularly an awareness of, and skills associated with, equitable teaching practices. In our two-year field-based program, CEs include community explorations, one-on-one and small group work with children, two student teaching practicums, and various school-community events. We describe the iterative design process undertaken to maximize the benefits yielded from CEs. After working with three cohorts of PTs for their entire professional training, we found that: 1) focusing attention on the intentional design and assessment of the mediational activities coupled with CEs leads to more nuanced understandings and enactments of culturally relevant teaching among PTs; and 2) CEs afford PTs abundant opportunities to shape complex identities as urban teachers. Specifically, we found that clinical experiences and corresponding mediational activities support PTsΓÇÖ understanding of families of color, allow them to recognize and address problematic schooling practices, and strengthen PTsΓÇÖ otherwise fragile critical consciousness. We conclude that strategic interventions can provide clarity for PTs around what has, indeed, been learned at particular intervals in the program, and what is left to be developed in the final practicum and beyond

Structural controls on the location, geometry and longevity of an intraplate volcanic system: the Tuatara Volcanic Field, Great South Basin, New Zealand

Intraplate volcanism is widely distributed across the continents, but the controls on the 3D geometry and longevity of individual volcanic systems remain poorly understood. Geophysical data provide insights into magma plumbing systems, but, as a result of the relatively low resolution of these techniques, it is difficult to evaluate how magma transits highly heterogeneous continental interiors. We use borehole-constrained 2D seismic reflection data to characterize the 3D geometry of the Tuatara Volcanic Field located offshore New Zealand's South Island and investigate its relationship with the pre-existing structure. This c. 270 km2 field is dominated by a dome-shaped lava edifice, surrounded and overlain by c. 69 volcanoes and >70 sills emplaced over 40 myr from the Late Cretaceous to Early Eocene (c. 85–45 Ma). The Tuatara Volcanic Field is located above a basement terrane boundary represented by the Livingstone Fault; the recently active Auckland Volcanic Field is similarly located along-strike on North Island. We suggest that the Livingstone Fault controlled the location of the Tuatara Volcanic Field by producing relief at the base of the lithosphere, thereby focussing lithospheric detachment over c. 40 myr, and provided a pathway that facilitated the ascent of magma. We highlight how observations from ancient intraplate volcanic systems may inform our understanding of active intraplate volcanic systems, including the Auckland Volcanic Field

Whiteness as a Barrier to Becoming a Culturally Relevant Teacher: Clinical Experiences and the Role of Supervision

Clinical experiences are crucial to the development of prospective teachers (PTs), especially the student teaching practicum. While the dynamics of schools are beginning to change in response to documented inequities for students, particularly students of color, the student teaching practicum remains largely unchanged and unchallenged with regard to addressing racism, oppression and white dominance. In this study, we explore PTs’ experiences and discourse in the context of student teaching in urban schools and the corresponding supervision of student teachers. Specifically, we examine the ways in which whiteness and racism obstruct the development of culturally relevant teachers. The data illuminate key insights into the ways in which PTs maneuver to avoid critical self-interrogation in relation to racism and inequities in schools. We conclude that clinical supervision experiences are opportunities to hide behind and/or challenge whiteness, and that the role of the supervisor is critical in facilitating the exposure to, and enactment of, culturally relevant pedagogy

Model-based spacecraft and mission design for the evaluation of technology

In order to meet the future vision of robotic missions, engineers will face intricate mission concepts, new operational approaches, and technologies that have yet to be developed. The concept of smaller, model driven projects helps this transition by including life-cycle cost as part of the decision making process. For example, since planetary exploration missions have cost ceilings and short development periods, heritage flight hardware is utilized. However, conceptual designs that rely solely on heritage technology will result in estimates that may not be truly representative of the actual mission being designed and built. The Laboratory for Spacecraft and Mission Design (LSMD) at the California Institute of Technology is developing integrated concurrent models for mass and cost estimations. The purpose of this project is to quantify the infusion of specific technologies where the data would be useful in guiding technology developments leading up to a mission. This paper introduces the design-to-cost model to determine the implications of various technologies on the spacecraft system in a collaborative engineering environment. In addition, comparisons of the benefits of new or advanced technologies for future deep space missions are examined

Failure of interpolation in the intuitionistic logic of constant domains

A comparison of maternal and newborn health services costs in Sindh Pakistan

Pakistani women suffer the highest rate of maternal mortality in South Asia. A lack of comprehensive knowledge about maternal and newborn health (MNH) services costs impedes policy decisions to maximize the benefit from existing, as well as emerging, MNH interventions in Pakistan. We compared MNH service costs at different levels of care. A cross-sectional survey was conducted during January to March 2016 as part of a large economic evaluation in Sindh, Pakistan. Health providers and facilities were selected from a sampling frame, inclusive of public and private sectors. This study utilized a broad perspective (i.e. costs to the health system and patients/families). The unit costs of MNH services were determined through a simultaneous allocation method in the public facilities; and patient billing department in the private facilities. Descriptive analysis was performed, and an analysis of variance (ANOVA) test was applied to compare overall mean costs both within and between health facilities. A total of 31 eligible health providers and facilities (n = 25 in private; n = 7 in public) were included in the final analysis. An ambulatory visit (AV) for routine antenatal care (ANC) costs $3.6 and$0.9 at secondary- and tertiary-level public facilities, respectively. In the private sector, the costs of an AV for ANC were slightly less ($2.8) at secondary-level and much higher ($6) at tertiary-level facilities compared to the public sector. Diagnostic test costs were much higher in private facilities. The average costs of inpatient admissions were $30.5 at general ward (GW), and$151 at the intensive care unit (ICU) in public facilities. In-patient admissions costs were lower such as $9.3 at GW and$36.5 at ICU in private facilities. Understanding cost is critical to guide decisions of resource allocation within the public sector; and risk mitigation for excessive OOP costs through third party payer for services in the private secto
