Kinds of Science Center Selected Abstracts"A Large Object with a Small Museum": A Narrative Analysis of Tlotlo's Experience of an Astronomy Science CenterCURATOR THE MUSEUM JOURNAL, Issue 3 2009Anthony Lelliott We illustrate the power of narrative in illuminating the importance of the student's perspective in understanding the conditions for learning in a museum setting. Using principles of narrative presentation, the paper describes Tlotlo's thinking throughout his participation in a school visit to the visitors' center at a radio telescope. The paper discusses six features of the visit: student misconceptions; inadequate preparation and followup; memories and imaginings; enjoyment; discussing the visit afterwards; and socioeconomic constraints on visits. These features are examined within the context of a developing country: both confirming previous research on school visits and providing new insights into how such visits can be interpreted. The significance of narrative analysis for science center educators is discussed and suggested as appropriate for current research in museums.

Hartnett Ph.D. Abstract:, This research tests the accuracy of age estimation from the pubic bone. Specimens were collected from decedents of known age, sex, and race at the Forensic Science Center (FSC) in Phoenix, Arizona. The collection consists of pubic bones and fourth rib ends from 419 males and 211 females, ranging in age from 18 to 99. Age-at-death was estimated by three observers using the Suchey,Brooks method. The correlation results indicate that there are significant differences in the observed versus actual ages (r = 0.68169, p < 0.001) and that there are significant interobserver differences. No significant differences were found in the intra-observer tests. The FSC pubic bones were sorted based on morphology without knowing age. New descriptions and age ranges were created. A phase seven was described and is comprised of males and females over 70 years of age-at-death.

[source] Endoscopic Vertical Partial Laryngectomy,THE LARYNGOSCOPE, Issue 2 2004R Kim Davis MD Abstract Objective: To explain the significant difference between microlaryngoscopy with cordectomy and endoscopic vertical partial laryngectomy (EVPL), to describe the efficacy of EVPL on T1b and T2 glottic squamous cell carcinoma, and to evaluate EVPL with postoperative irradiation in T2 glottic cancer with impaired true vocal cord mobility. Study Design: Retrospective review. Methods: Twenty-six patients seen at the University of Utah Health Science Center between 1987 and 2000 with bilateral T1 (T1b) or T2 squamous cell carcinoma of the glottic larynx underwent EVPL. T2 cancers were classified as follows: a = unilateral disease, b = bilateral disease; i = impaired mobility. T1b and T2a glottic cancer patients received surgery alone, whereas impaired mobility patients (T2ai + T2bi) patients received surgery followed by planned postoperative irradiation. Patients were assessed for primary site control, perioperative and long-term complications, and ultimate cancer control. Results: Survival in the total group was 88.5%, with local control at 92.3%. The two recurrent patients were salvaged by total laryngectomy. For the whole group, anterior commissure involvement was present in 57.7% (15 of 26). Thirteen T2 (5 T2ai + 8 T2bi) carcinoma patients underwent combined therapy, with 8 (61.5%) of these patients having anterior commissure involvement. Two of these patients were upstaged at surgery, one to T3 and one to T4. Local control was 84.5%. Thirteen patients were treated by surgery only, with five of these patients having failed previous irradiation. Survival was 92.3% and local control 100%. This group included two T2bi patients, two patients upstaged to T4 on the basis of extension beyond the subglottis to the anterior wall of the trachea, 3 T2b, and 6 T2a patients. Anterior commissure involvement was seen in 7 (53.8%) of these patients. Conclusions: EVPL alone controlled all T1b and T2a glottic cancer patients, even in the presence of greater than 50% anterior commissure involvement. The significant difference between EVPL and classical microlaryngoscopy with cordectomy was carefully described. EVPL with planned postoperative irradiation resulted in an 85% local control rate in clinically staged T2ai and T2bi cancer patients, including the three upstaged patients.

Methods Genomic DNA samples and clinical data were collected from the Scleroderma Family Registry and DNA Repository at the University of Texas Health Science Center at Houston. A total of 740 subjects were studied; 203 of them had diffuse cutaneous SSc (dcSSc), 283 had limited cutaneous SSc (lcSSc), and the remaining 254 healthy subjects served as controls. Association analyses were performed on the whole data set and on patient and sex subsets. Significant relationships were determined between clinical variables and MIF polymorphisms for each disease subtype in the studied groups. Results The frequency of the ,173*C MIF allele, which was previously reported to be associated with high production of MIF, was lower in the lcSSc group (12.6%) than in the dcSSc (19.2%) or control (18.5%) groups (P = 0.010 and P = 0.011, respectively). Haplotype analysis for 2 closely linked polymorphisms in the MIF promoter showed that in white subjects with lcSSc or dcSSc, the lcSSc population had a significantly lower representation of the high-expression MIF haplotype defined by ,173*C and ,794 with 7 CATT repeats (C7) (P = 0.015, odds ratio 1.94 [95% confidence interval 1.14,3.32]). Fibroblasts encoding the C7 MIF haplotype were observed to produce more MIF upon in vitro stimulation than those with a non-C7 haplotype. Conclusion Functional promoter polymorphisms in the MIF gene affect the clinical presentation of SSc. The proinflammatory haplotype defined by C7 is underrepresented in patients with lcSSc.

Motch Abstract We present results from a project conducted by the Survey Science Center of the XMM-Newton satellite and aiming at the identification and characterisation of serendipitous EPIC sources at low galactic latitudes. Deep multi-colour optical imaging and spectroscopic observations have been obtained in the framework of several observing campaigns carried out at ING, CFHT and ESO. These observations have lead to a number of optical identifications, mostly with active stars. We describe the identified source content at low galactic latitudes and compare stellar populations properties at low and high galactic latitudes with those expected from stellar X-ray count models.

[source] Marginalization of Midwives in the United States: New Responses to an Old StoryBIRTH, Issue 2 2008Judith P Rooks CNM ABSTRACT: This column addresses issues raised by an intensive study of the circumstances and actions that resulted in the closure of two long-standing, successful nurse-midwifery services in a large United States city in 2003. Dr. Steffie Goodman of the School of Nursing, University of Colorado Health Science Center in Denver, USA, conducted 52 in-depth interviews with midwives, nurses, administrators, childbirth educators, policymakers, and physicians in an effort to understand how and why these two services were closed and what their closures revealed about the general underutilization of midwives in contemporary U.S. health care. Goodman concluded that economics, power, and authority converge in a way that allows persons in positions of institutional power and authority to make self-serving decisions that diminish access to midwifery services and that they can do so without any public accountability for their actions.

[source] University faculty perceptions of the health risks related to cigarettes and smokeless tobaccoDRUG AND ALCOHOL REVIEW, Issue 2 2010NICHOLAS PEIPER Abstract Introduction and Aims. It is now widely understood by tobacco research and policy experts that smokeless tobacco (ST) use confers significantly less risk than smoking, but no studies have assessed tobacco risk perceptions in highly educated populations. The purpose of this study was to explore the perception of risks related to smoking and ST use among full-time faculty on two campuses at the University of Louisville. Design and Methods. In October 2007, a survey that quantified risk perceptions of cigarette smoking and ST use with respect to four health domains (general health, heart attack/stroke, all cancer, oral cancer) was sent to 1610 full-time faculty at the Belknap and the Health Sciences Center (HSC) campuses of the University of Louisville, and 597 (37%) returned a completed survey. Results. Overall, cigarettes were considered as high risk for all health domains by large majorities (75,97%). Except for heart attack/stroke, ST was also considered as high risk by the majority of faculty (69,87%), and at least half perceived cigarettes and ST to be equally harmful across all domains. HSC faculty had somewhat more accurate risk perceptions than Belknap faculty for ST, but both groups overestimated the risks, especially for oral cancer. Discussion and Conclusions. This study found that the risks of ST use are overestimated and conflated to that of cigarettes among highly educated professionals, demonstrating the need for better education about the risks of tobacco use and for communication of accurate information by health organisations and agencies.[Peiper N, Stone R, Van Zyl R & Rodu B.

Drug Alcohol Rev 2010] [source] Sirolimus-based immunosuppression following liver transplantation for hepatocellular carcinomaLIVER TRANSPLANTATION, Issue 5 2008Michael A. Zimmerman Experience with sirolimus (SRL)-based immunosuppression following orthotopic liver transplantation (OLT) is rapidly accumulating. In combination with calcineurin inhibitors (CNIs), SRL may reduce the incidence of acute rejection and lower overall required drug levels. This study sought to quantify long-term outcome following OLT in patients with cirrhosis and concomitant hepatocellular carcinoma (HCC) who were treated with an SRL-based regimen as a primary therapy. From January 2000 to June 2007, 97 patients underwent OLT for end-stage liver disease and HCC at the University of Colorado Health Sciences Center. Of those, 45 patients received SRL, in addition to CNIs, as a component of their primary immunosuppression regimen post-OLT. Conversely, 52 patients received the standard immunosuppression regimen including CNIs, mycophenolate mofetil, and corticosteroids. The 2 treatment groups were compared with respect to the following variables: age, gender, tumor stage by explant, grade, size, presence of vascular invasion, focality, Child's class, baseline creatinine, and warm and cold ischemic times. The 2 groups were comparable by all factors save for cold ischemic time, which was significantly longer in the CNI-treated group. Overall survival at 1 and 5 years post-OLT for patients treated with SRL was 95.5% and 78.8%, respectively. Conversely, survival in patients treated with CNIs exclusively at the same time intervals was 83% and 62%. Although there was no difference in the incidence of major complications, the SRL group experienced a modest improvement in renal function. Cumulatively, these data suggest a potential survival benefit with SRL-based therapy in patients undergoing OLT for end-stage liver disease and concomitant malignancy.

Nottingham MPH The outcome is an evolving universitycommunity partnership designed to meet changing workforce and community health needs in the heart of rural Appalachia. West Virginia University's (WVU's) application of the original Carnegie Commission AHEC recommendations (1970) resulted in the Charleston AHEC, now part of the Robert C. Byrd Health Sciences Center of WVU. AHEC today trains more than 135 residents and interns, and one-third of the third-year and fourth-year WVU medical students. Charleston offers clinical and continuing education for nurses, dentists, pharmacists, and allied health professionals. A health sciences library, distance learning, and a neiwork of primary care clinics help define Charleston's unique AHEC role. This AHEC hub continues to meet the classic Carnegie goals of recruiting and retaining health professionals, and providing access to care in the original service area and statewide. Based on the Charleston experience, four new federally funded AHECs are being developed to link rural primary care residencies with the state-funded West Virginia rural health education partnerships. These rural consortia AHECs are applying the concept of community competency, a performance-based methodology, to integrate learning while achieving the goals of Healthy People 2010. [source] Ear, Nose and Throat Disorders in Children With Down SyndromeTHE LARYNGOSCOPE, Issue 2 2003Ron B. Mitchell MD Abstract Objective To document the reasons for which children with Down syndrome were referred to a pediatric otolaryngology practice, the underlying causes for these referrals, and the complications of routine surgical therapy. Study Design The study is a retrospective review of children referred to the Pediatric Otolaryngology Clinic at the University of New Mexico Health Sciences Center (Albuquerque, NM) during a period of 2.5 years. Methods Data were collected on 55 parameters related to ethnicity, demographics, diagnosis, surgical therapy, complications, and systemic comorbid conditions. Results The ethnicity of the study population was predominantly Hispanic or Latino (62%). The majority of children (76%) were referred for upper airway obstruction. Obstructive sleep apnea and laryngomalacia were the most common disorders in these children. An otological disorder was diagnosed in 70% of the children. Complications occurred after 27% of procedures for insertion of pressure equalization (PE) tubes to treat recurrent otitis media. Systemic comorbid conditions were present in 93% of the children, and the most common was gastroesophageal reflux disease. Conclusions Obstructive sleep apnea and laryngomalacia were the most common reasons for referral of children with Down syndrome. Routine surgical procedures that required general anesthesia caused complications that are not common in other children. Treatment for systemic comorbid conditions should be considered as a component of therapy for otolaryngological disorders in children with Down syndrome. [source] Integrating pediatric hospitalists in the academic health science center: Practice and perceptions in a canadian center,,JOURNAL OF HOSPITAL MEDICINE, Issue 4 2010FRCPC, Sanjay Mahant MD Abstract BACKGROUND: The integration of hospitalists in academic settings has been identified as a challenge to the hospitalist movement. The Division of Pediatric Medicine, Hospital for Sick Children, Toronto, was established in 1981, providing a rich resource to examine this field in the academic context and inform academic program development. OBJECTIVES: To explore the characteristics, practice, perceptions, and contributions of pediatric hospital medicine in an academic health science center (AHSC). METHODS: A cross-sectional survey of physicians attending on the pediatric medicine inpatient unit (PMIU) (n = 20). RESULTS: Clinical activity included attending on the PMIU, consultation and comanagement outside the PMIU, and outpatient care of "hospital intense" patients. There was a high level of engagement in research, education, and quality improvement activities. Perceived advantages to a career as a hospitalist included: working in a team; generalist approach to care; stability relative to community practice; intellectually stimulating and rewarding work; and growing area for scholarship. Perceived disadvantages to a career as a hospitalist included: burnout; recognition and respect; and lack of long-term relationships with patients. Themes regarding barriers to establishing a career as a hospitalist in an AHSC were as follows: burnout; time and skills to develop an academic niche; balance between clinical and academic priorities; and system for career advancement. CONCLUSIONS: The contributions of pediatric hospitalists to the academic mission were diverse. Fellowship training, faculty development, and balance between time allocated to direct patient care and academic pursuits should be defined. This will help ensure career development, viability, and realization of excellence in the academic context. Journal of Hospital Medicine 2010;5:228,233. © 2010 Society of Hospital Medicine. [source] Science learning in a leisure settingJOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 2 2010John H. Falk Abstract Most people visit a science center in order to satisfy specific leisure-related needs; needs which may or may not actually include science learning. Falk proposed that an individual's identity-related motivations provide a useful lens through which to understand adult free-choice science learning in leisure settings. Over a 3-year period the authors collected in-depth data on a random sample of visitors to a large recently opened, hands-on, interactive science center; collecting information on why people visited, what they did within the science center, what they knew about the subject presented upon entering and exiting, and what each individual's long-term self-perceptions of their own learning was. Presented is a qualitative analysis of visitor interviews collected roughly 2 years after the initial visit. Although there was evidence for a range of science learning outcomes, outcomes did appear to be strongly influenced by visitor's entering identity-related motivations. However, the data also suggested that not only were the motivational goals of a science center visit important in determining outcomes, so too were the criteria by which visitors judged satisfaction of those goals; in particular whether goal satisfaction required external or merely internal validation. The implications for future informal science education research and practice are discussed. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 47:194,212, 2010 [source] |
