Preservice Elementary Teachers’ Early Practice of Eliciting and Responding to Students’ Mathematical Thinking.

Learning to teach involves making a shift from layperson to teaching professional over the course of formal preparation. This shift requires putting aside naïve perceptions of self and teaching in favor of an informed conception of the professional teacher focused on others’ –– that is, students’ –– thinking and understanding. Although many practices are central to the work of teaching, the practice of eliciting and responding to student thinking is crucial for teachers to gain insight into their students’ ideas and ways of thinking. This dissertation investigated novice teachers’ practice of eliciting and responding to student thinking at the beginning of their formal teacher preparation. Based on analysis of 27 preservice teachers’ mathematics discussions during their first four weeks of preparation, the study analyzed the kinds of initial eliciting questions that the preservice teachers posed, and the kinds of responses they gave to students’ contributions. The analyses showed that although preservice teachers had some skill in eliciting student thinking they were inconsistent in the methods of eliciting they used across teaching episodes. When responding to students, preservice teachers in this study often used guiding prompts even after students provided correct answers. Results from this study offer insights into specific aspects of eliciting and interpreting student thinking with which beginning teachers might need support in order to attend to student thinking. Some of the findings also signaled that there may be tendencies that preservice teachers need to unlearn as part of their preparation in order to become skilled at eliciting and responding to student thinking. The analysis of early eliciting and responding to student thinking practice can inform how teacher educators look at, talk about, and evaluate preservice teachers’ practice.PhDEducational StudiesUniversity of Michigan, Horace H.

Participatory parks planning : exploring democratic design as a tool to mediate cultural conflict over neighborhood green space

Thesis (M.C.P.)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, 2005.Includes bibliographical references (p. 121-128).America's park history has largely been a story of the commodification and representation of nature, from the idyllic naturescapes of the mid-nineteenth century to the reform parks and playgrounds of the City Beautiful era. Not until this century, however, has it become clear that this interpretation of nature is often an Anglo-centric vision, influenced by Western notions of landscape and the frontier. Rarely do American urban parks consider or reflect the non-Western ideals of nature; consequently, these parks are often culturally inaccessible to new immigrants and communities of color. As the United States becomes an increasingly pluralistic society, the need grows for open space that can foster interaction between different ethnic and racial groups and that can serve multiple user groups simultaneously. Parks-and particularly, American parks- are largely products of political will and reflections of power structures, at least with respect to their locations and designs. Design decisions dictate who feels welcome in a space and who feels excluded; similarly, programming choices-often informed by design-can define a park's audience. Thus, a discussion of power in the context of planning provides a critical link in considering reflections of culture in park design, as well. To that end, this thesis will examine the intersection of the discourses on urban parks, citizen participation, and nature, beginning with an exploration of how the historical narrative of parks planning in the United States can be reframed to reflect the contemporaneous histories of America's communities of color.(cont.) Through this new lens, the thesis will examine strategies for understanding and planning multicultural open space in urban environments, focusing specifically on democratic design processes as a tool for effecting change. Democratic design, a participatory planning strategy that empowers the community very directly as an actor in the design process, has rarely been applied to parks planning. However, recent experiments with democratic design processes for small community parks in the Eastlake neighborhood of Oakland, California and the Phillips neighborhood of Minneapolis, Minnesota provide unique opportunities to explore the potential of this nascent planning strategy as a mechanism for creating multicultural neighborhood parks in the center city and mitigating the problem of park underuse.by Diana R.

KIR-HLA and Maternal-Infant HIV-1 Transmission in Sub-Saharan Africa

Numerous studies have suggested a role for natural killer (NK) cells in attenuation of HIV-1 disease progression via recognition by killer-cell immunoglobulin-like receptors (KIRs) of specific HLA class I molecules. The role of KIR and HLA class I has not been addressed in the context of maternal-infant HIV-1 transmission. KIR and HLA class I B and C genes from 224 HIV-1-infected mothers and 222 infants (72 infected and 150 uninfected) from South Africa were characterized. Although a number of significant associations were determined in both the total group and in the nevirapine (NVP) exposed group, the most significant findings involved KIR2DL2 and KIR2DL3 and HLA-C. KIR2DL2/KIR2DL3 was underrepresented in intrapartum (IP)-transmitting mothers compared to non-transmitting (NT) mothers (P = 0.008) and remained significant (P = 0.036) after correction for maternal viral load (MVL). Homozygosity for KIR2DL3 alone and in combination with HLA-C allotype heterozygosity (C1C2) was elevated in IP-transmitting mothers compared to NT mothers (P = 0.034 and P = 0.01 respectively), and after MVL correction (P = 0.033 and P = 0.027, respectively). In infants, KIR2DL3 in combination with its HLA-C1 ligand (C1) as well as homozygosity for KIR2DL3 with C1C2, were both found to be underrepresented in infected infants compared to exposed uninfected infants in the total group (P = 0.06 and P = 0.038, respectively) and in the sub-group of infants whose mothers received NVP (P = 0.007 and P = 0.03, respectively). These associations were stronger post MVL adjustment (total group: P = 0.02 and P = 0.009, respectively; NVP group: P = 0.004 and P = 0.02, respectively). Upon stratification according to low and high MVL, all significant associations fell within the low MVL group, suggesting that with low viral load, the effects of genotype can be more easily detected. In conclusion this study has identified a number of significant associations that suggest an important role for NK cells in maternal-to-infant HIV-1 transmission

Real-Time Identification of Serious Infection in Geriatric Patients Using Clinical Information System Surveillance

To develop and characterize an automated syndromic surveillance mechanism for early identification of older emergency department (ED) patients with possible life-threatening infection. DESIGN : Prospective, consecutive-enrollment, single-site observational study. SETTING : A large university medical center with an annual ED census of 75,273. PARTICIPANTS : Patients aged 70 and older admitted to the ED and having two or more systemic inflammatory response syndrome (SIRS) criteria during their ED stay. MEASUREMENTS : A search algorithm was developed to screen the census of the ED through its clinical information system. A study coordinator confirmed all patients electronically identified as having a probable infectious explanation for their visit. RESULTS : Infection accounted for 28% of ED and 34% of final hospital diagnoses. Identification using the software tool alone carried a 1.63 relative risk of infection (95% confidence interval CI=1.09–2.44) compared with other ED patients sufficiently ill to require admission. Follow-up confirmation by a study coordinator increased the risk to 3.06 (95% CI=2.11–4.44). The sensitivity of the strategy overall was modest (14%), but patients identified were likely to have an infectious diagnosis (specificity=98%). The most common SIRS criterion triggering the electronic notification was the combination of tachycardia and tachypnea. CONCLUSION : A simple clinical informatics algorithm can detect infection in elderly patients in real time with high specificity. The utility of this tool for research and clinical care may be substantial.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66036/1/j.1532-5415.2008.02094.x.pd

Reducing Decisional Conflict and Enhancing Satisfaction with Information among Women Considering Breast Reconstruction following Mastectomy: Results from the BRECONDA Randomized Controlled Trial

Background: Deciding whether or not to have breast reconstruction following breast cancer diagnosis is a complex decision process. This randomized controlled trial assessed the impact of an online decision aid [Breast RECONstruction Decision Aid (BRECONDA)] on breast reconstruction decision-making. Methods: Women (n = 222) diagnosed with breast cancer or ductal carcinoma in situ, and eligible for reconstruction following mastectomy, completed an online baseline questionnaire. They were then assigned randomly to receive either standard online information about breast reconstruction (control) or standard information plus access to BRECONDA (intervention). Participants then completed questionnaires at 1 and 6 months after randomization. The primary outcome was participants' decisional conflict 1 month after exposure to the intervention. Secondary outcomes included decisional conflict at 6 months, satisfaction with information at 1 and 6 months, and 6-month decisional regret. Results: Linear mixed-model analyses revealed that 1-month decisional conflict was significantly lower in the intervention group (27.18) compared with the control group (35.5). This difference was also sustained at the 6-month follow-up. Intervention participants reported greater satisfaction with information at 1- and 6-month follow-up, and there was a nonsignificant trend for lower decisional regret in the intervention group at 6-month follow-up. Intervention participants' ratings for BRECONDA demonstrated high user acceptability and overall satisfaction. Conclusions: Women who accessed BRECONDA benefited by experiencing significantly less decisional conflict and being more satisfied with information regarding the reconstruction decisional process than women receiving standard care alone. These findings support the efficacy of BRECONDA in helping women to arrive at their breast reconstruction decision

Development of a taxonomy to describe massage treatments for musculoskeletal pain

BACKGROUND: One of the challenges in conducting research in the field of massage and bodywork is the lack of consistent terminology for describing the treatments given by massage therapists. The objective of this study was to develop a taxonomy to describe what massage therapists actually do when giving a massage to patients with musculoskeletal pain. METHODS: After conducting a review of the massage treatment literature for musculoskeletal pain, a list of candidate techniques was generated for possible inclusion in the taxonomy. This list was modified after discussions with a senior massage therapist educator and seven experienced massage therapists participating in a study of massage for neck pain. RESULTS: The taxonomy was conceptualized as a three level classification system, principal goals of treatment, styles, and techniques. Four categories described the principal goal of treatment (i.e., relaxation massage, clinical massage, movement re-education and energy work). Each principal goal of treatment could be met using a number of different styles, with each style consisting of a number of specific techniques. A total of 36 distinct techniques were identified and described, many of which could be included in multiple styles. CONCLUSION: A new classification system is presented whereby practitioners using different styles of massage can describe the techniques they employ using consistent terminology. This system could help facilitate standardized reporting of massage interventions
