Authors: Su Huadong 
Published: March 2016

AbstractThe unitary Cayley graph of a ringR, denoted Γ(R), is the simple graph defined on all elements ofR, and where two verticesxandyare adjacent if and only ifx−yis a unit inR. The largest distance between all pairs of vertices of a graphGis called the diameter ofGand is denoted by diam(G). It is proved that for each integern≥ 1, there exists a ringRsuch that diam(Γ(R)) =n. We also show that diam(Γ(R)) ∊ {1, 2, 3,∞} for a ringRwithR/J(R) self-injective and classify all those rings with diam(Γ(R)) = 1, 2, 3, and ∞, respectively.

ABSTRACT Many institutions are seeking ways to enhance their surgical trainees' quality improvement (QI) skills.Background To educate trainees about the importance of lifelong performance improvement, chief residents at New York Presbyterian Hospital–Weill Cornell Medicine are members of a multidisciplinary QI team tasked with improving surgical outcomes. We describe the process and the results of this effort.Objective Our analysis used 2 data sources to assess complication rates: the National Surgical Quality Improvement Program (NSQIP) and ECOMP, our own internal complication database. Chief residents met with a multidisciplinary QI team to review complication rates from both data sources. Chief residents performed a case-by-case analysis of complications and a literature search in areas requiring improvement. Based on this information, chief residents met with the multidisciplinary team to select interventions for implementation, and delivered QI-focused grand rounds summarizing the QI process and new interventions.Methods Since 2009, chief residents have presented 16 QI-focused grand rounds. Urinary tract infections (UTIs) and surgical site infections (SSIs) were the most frequently discussed. Interventions to improve UTIs and SSIs were introduced to the department of surgery through these reports in 2011 and 2012. During this time we saw improvement in outcomes as measured by NSQIP odds ratio.Results Departmental grand rounds are a suitable forum to review NSQIP data and our internal, resident-collected data as a means to engage chief residents in QI improvement, and can serve as a model for other institutions to engage surgery residents in QI projects.Conclusions

ABSTRACT

The patient-centered medical home (PCMH) provides a setting to enhance resident training in systems-based practice. Few studies have addressed the impact of PCMHs on resident knowledge and confidence.Background

The goal of this study was to evaluate resident knowledge, confidence, behavior, and patient outcomes in a PCMH.Objective

Our curriculum emphasized patient panel report card interpretation, a telephone medicine curriculum, and interdisciplinary team-based care of chronic medical conditions. We measured resident satisfaction, knowledge, and confidence. Patient outcomes included hemoglobin A1c (HbA1c) and blood pressures. Prescores and postscores were compared using paired t tests for continuous measures and McNemar's test for binary measures.Methods

A total of 154 residents were eligible for the curriculum. All residents participated in the curriculum, though not all residents completed the evaluation. Completion rates for paired pre-post knowledge and confidence surveys were 38% and 37%, respectively. Nearly 80% (69 of 87) of residents indicated that the curriculum was above average or outstanding. Our evaluation revealed very small immediate improvements in knowledge and confidence. No significant improvement in patients' HbA1cs or blood pressures occurred after the curriculum.Results

Explicit training to work in a PCMH was feasible and resulted in high levels of resident satisfaction and immediate small improvements in knowledge and confidence.Conclusions

ABSTRACT

Emergency medicine (EM) residency programs can provide up to 20% of their planned didactic experiences asynchronously through the Individualized Interactive Instruction (III) initiative. Although blogs and podcasts provide potential material for III content, programs often struggle with identifying quality online content.Background

To develop and implement a process to curate quality EM content on blogs and podcasts for resident education and III credit.Objective

We developed the Approved Instructional Resources (AIR) Series on the Academic Life in Emergency Medicine website. Monthly, an editorial board identifies, peer reviews, and writes assessment questions for high-quality blog/podcast content. Eight educators rate each post using a standardized scoring instrument. Posts scoring ≥ 30 of 35 points are awarded an AIR badge and featured in the series. Enrolled residents can complete an assessment quiz for III credit. After 12 months of implementation, we report on program feasibility, enrollment rate, web analytics, and resident satisfaction scores.Methods

As of June 2015, 65 EM residency programs are enrolled in the AIR Series, and 2140 AIR quizzes have been completed. A total of 96% (2064 of 2140) of participants agree or strongly agree that the activity would improve their clinical competency, 98% (2098 of 2140) plan to use the AIR Series for III credit, and 97% (2077 of 2140) plan to use it again in the future.Results

The AIR Series is a national asynchronous EM curriculum featuring quality blogs and podcasts. It uses a national expert panel and novel scoring instrument to peer review web-based educational resources.Conclusions

Authors: Musgrove John L , Morris Jason , Estrada Carlos A , Kraemer Ryan R 
Published: March 2016

ABSTRACT

Published clinical problem solving exercises have emerged as a common tool to illustrate aspects of the clinical reasoning process. The specific clinical reasoning terms mentioned in such exercises is unknown.Background

We identified which clinical reasoning terms are mentioned in published clinical problem solving exercises and compared them to clinical reasoning terms given high priority by clinician educators.Objective

A convenience sample of clinician educators prioritized a list of clinical reasoning terms (whether to include, weight percentage of top 20 terms). The authors then electronically searched the terms in the text of published reports of 4 internal medicine journals between January 2010 and May 2013.Methods

The top 5 clinical reasoning terms ranked by educators were dual-process thinking (weight percentage = 24%), problem representation (12%), illness scripts (9%), hypothesis generation (7%), and problem categorization (7%). The top clinical reasoning terms mentioned in the text of 79 published reports were context specificity (n = 20, 25%), bias (n = 13, 17%), dual-process thinking (n = 11, 14%), illness scripts (n = 11, 14%), and problem representation (n = 10, 13%). Context specificity and bias were not ranked highly by educators.Results

Some core concepts of modern clinical reasoning theory ranked highly by educators are mentioned explicitly in published clinical problem solving exercises. However, some highly ranked terms were not used, and some terms used were not ranked by the clinician educators. Effort to teach clinical reasoning to trainees may benefit from a common nomenclature of clinical reasoning terms.Conclusions

Abstract. A database containing the global and diffuse components of the surface solar hourly irradiation measured from 1 January 2004 to 31 December 2010 at eight stations of the Egyptian Meteorological Authority is presented. For three of these sites (Cairo, Aswan and El-Farafra), the direct component is also available. In addition, a series of meteorological variables including surface pressure, relative humidity, temperature, wind speed and direction is provided at the same hourly resolution at all stations. The details of the experimental sites and instruments used for the acquisition are given. Special attention is paid to the quality of the data and the procedure applied to flag suspicious or erroneous measurements is described in detail. Between 88 and 99  % of the daytime measurements are validated by this quality control. Except at Barrani where the number is lower (13 500), between 20 000 and 29 000 measurements of global and diffuse hourly irradiation are available at all sites for the 7-year period. Similarly, from 9000 to 13 000 measurements of direct hourly irradiation values are provided for the three sites where this component is measured. With its high temporal resolution this consistent irradiation and meteorological database constitutes a reliable source to estimate the potential of solar energy in Egypt. It is also adapted to the study of high-frequency atmospheric processes such as the impact of aerosols on atmospheric radiative transfer. It is planned to update regularly the current 2004–2010 database, which has been placed on the PANGAEA repository (doi:10.1594/PANGAEA.848804) and contains the individual meteorological and irradiation data files of the eight stations.
Comparing CFSR and conventional weather data for discharge and soil loss modelling with SWAT in small catchments in the Ethiopian Highlands
Authors: Roth Vincent , Lemann Tatenda 
Published: March 2016

Abstract. Accurate rainfall data are the key input parameter for modelling river discharge and soil loss. Remote areas of Ethiopia often lack adequate precipitation data and where these data are available, there might be substantial temporal or spatial gaps. To counter this challenge, the Climate Forecast System Reanalysis (CFSR) of the National Centers for Environmental Prediction (NCEP) readily provides weather data for any geographic location on earth between 1979 and 2014. This study assesses the applicability of CFSR weather data to three watersheds in the Blue Nile Basin in Ethiopia. To this end, the Soil and Water Assessment Tool (SWAT) was set up to simulate discharge and soil loss, using CFSR and conventional weather data, in three small-scale watersheds ranging from 112 to 477 ha. Calibrated simulation results were compared to observed river discharge and observed soil loss over a period of 32 years. The conventional weather data resulted in very good discharge outputs for all three watersheds, while the CFSR weather data resulted in unsatisfactory discharge outputs for all of the three gauging stations. Soil loss simulation with conventional weather inputs yielded satisfactory outputs for two of three watersheds, while the CFSR weather input resulted in three unsatisfactory results. Overall, the simulations with the conventional data resulted in far better results for discharge and soil loss than simulations with CFSR data. The simulations with CFSR data were unable to adequately represent the specific regional climate for the three watersheds, performing even worse in climatic areas with two rainy seasons. Hence, CFSR data should not be used lightly in remote areas with no conventional weather data where no prior analysis is possible.

Abstract. Quantifying the potential impacts of climate change on water yield and ecosystem productivity is essential to developing sound watershed restoration plans, and ecosystem adaptation and mitigation strategies. This study links an ecohydrological model (Water Supply and Stress Index, WaSSI) with WRF (Weather Research and Forecasting Model) using dynamically downscaled climate data of the HadCM3 model under the IPCC SRES A2 emission scenario. We evaluated the future (2031–2060) changes in evapotranspiration (ET), water yield (Q) and gross primary productivity (GPP) from the baseline period of 1979–2007 across the 82 773 watersheds (12-digit Hydrologic Unit Code level) in the coterminous US (CONUS). Across the CONUS, the future multi-year means show increases in annual precipitation (P) of 45 mm yr−1 (6 %), 1.8° C increase in temperature (T), 37 mm yr−1 (7 %) increase in ET, 9 mm yr−1 (3 %) increase in Q, and 106 gC m−2 yr−1 (9 %) increase in GPP. We found a large spatial variability in response to climate change across the CONUS 12-digit HUC watersheds, but in general, the majority would see consistent increases all variables evaluated. Over half of the watersheds, mostly found in the northeast and the southern part of the southwest, would see an increase in annual Q (> 100 mm yr−1 or 20 %). In addition, we also evaluated the future annual and monthly changes of hydrology and ecosystem productivity for the 18 Water Resource Regions (WRRs) or two-digit HUCs. The study provides an integrated method and example for comprehensive assessment of the potential impacts of climate change on watershed water balances and ecosystem productivity at high spatial and temporal resolutions. Results may be useful for policy-makers and land managers to formulate appropriate watershed-specific strategies for sustaining water and carbon sources in the face of climate change.

Purpose The pediatric population has benefited greatly by the evolution of ventricular assist devices (VADs) leading to miniaturization. Device design like the HeartWare® VAD allows for implantation in smaller patients or even as an implantable biventricular assist device. Case report A ten-year-old female patient (body surface area: 1.02 m2, 27 kg) waiting for 7 months for heart transplantation was admitted to the intensive care unit due to terminal heart failure. Transthoracal echocardiography revealed heart failure with an estimated ejection fraction of 15%, dilated left ventricle, moderate tricuspid and mitral regurgitation. Despite maximal medical therapy (including milrinone and 1 course of Levosimendan intravenous), her condition further worsened and mechanical circulatory support was indicated. After implantation of a HeartWare HVAD® device as an LVAD, a second pump was implanted as a right VAD (RVAD). The sewing ring of the HVAD was attached to the lateral wall of the right atrium. The device was implanted so that the axis of the inflow cannula was pointing towards the tricuspid valve. The outflow graft was anastomosed to the pulmonary artery truncus; the outflow graft diameter was not narrowed. Anticoagulation with IV heparin was started 8 hours postoperatively with a target antifactor Xa level of 0.3 to 0.6 IU/ml. The patient was extubated after 26 hours and fully mobilized. BVAD settings were: 2,300 revolutions per minute, calculated flow: 3.2 liters per minute and 2.7 W for the left side and 2,080 revolutions per minute, calculated flow: 3.3 L per minute and 2.1 W for the right side.

Published: March 2016

Purpose Exercise capacity is usually evaluated by peak oxygen consumption (peak-VO2). However, assessment of peak-VO2 in patients with a left ventricular assist device (LVAD) might not be the best method to provide insight into their daily life activity. The aim of this study was to assess the postoperative activity of LVAD patients using actigraphy and to compare these patients to a healthy and a heart-transplanted (HTx) population. Methods Activity was continuously monitored using wrist-accelerometers in LVAD patients after implantation, during 4 weeks of rehabilitation following hospital discharge, and at 2 follow-up assessments. Peak-VO2 values measured during rehabilitation were correlated with activity. Additionally, actigraphy data from LVAD recipients were compared with data measured in healthy and HTx subjects. Results After hospital discharge a significant increase in physical activity of LVAD recipients was observed (55 ± 28 vs. 102 ± 23 Activity Scores, n = 11, p = 0.002). During rehabilitation as well as at the follow-ups (140 ± 43 and 253 ± 33 days post-implantation) no significant increase in activity was observed. Peak-VO2 values correlated to daily activity both in LVAD and HTx patients (r > 0.5). Average daily activity was significantly lower in LVAD and HTx patients than in the healthy population (130 ± 30 and 148 ± 60 vs. 245 ± 63 Activity Score; n = 18 in each group, p < 0.001). Conclusions Activity in LVAD recipients increased substantially after hospital discharge with no further significant improvement observed during a period of 8.5 months. Similarly to the peak-VO2, also the daily activity of LVAD recipients was 53% compared to healthy subjects. These results highlight the need for an optimized physical therapy in this patient cohort.
“The Meaning of What You Mean Now”: Domestic and Psychological Spaces in More Stately Mansions
Authors: Lee E. Andrew 
Published: March 2016

Abstract
Sara Melody and Deborah Harford have often been viewed as allegorical representations of Simon Harford's mind, but this essay examines Sara and Deborah as intricately expressive characters in their own right who outgrew O'Neill's original intentions as the play became, in O'Neill's words, “oversize.” A close examination of the domestic spaces occupied by the women in More Stately Mansions reveals the women's complex and antithetical personalities, as well as their underlying psychological motives as they seek to manipulate Simon Harford. Ultimately, none of the play's domestic spaces offers refuge for any of the characters, resulting in an epilogue that is anticlimactic.
Desire under Dylan: Robert Falls, Bob Dylan, and the Domestic Tragedy of Eugene O'Neill
Authors: Maley Patrick 
Published: March 2016

Abstract
This article suggests that the 2009 production of Desire under the Elms, directed by Robert Falls first at Chicago's Goodman Theater and later at Broadway's St. James Theater, shifts the tragic crux of the play away from the adulterous sex in the parlor and onto the shoulders of Ephraim Cabot, who errs in attempting to establish normative domesticity. The Falls production, which was without elms, featured a full-sized house hanging above the stage surface, and inserted in the space between O'Neill's first two acts a long montage of domestic chores set to the soundtrack of Bob Dylan's “Not Dark Yet.” These factors and others contribute to the performative condemnation of Ephraim Cabot, underscoring how Desire belongs in the company of many other O'Neill plays that are deeply critical of normative domesticity.
