Improving teaching on an inpatient pediatrics service: a retrospective analysis of a program change
Background:
The traditional role of the faculty inpatient attending providing clinical care and effectively teaching residents and medical students is threatened by increasing documentation requirements, pressures to increase clinical productivity, and insufficient funding available for medical education. In order to sustain and improve clinical education on a general pediatric inpatient service, we instituted a comprehensive program change. Our program consisted of creating detailed job descriptions, setting clear expectations, and providing salary support for faculty inpatient attending physicians serving in clinical and educational roles. This study was aimed at assessing the impact of this program change on the learnersâ perceptions of their faculty attending physicians and learnersâ experiences on the inpatient rotations.
Methods:
We analyzed resident and medical student electronic evaluations of both clinical and teaching faculty attending physician characteristics, as well as resident evaluations of an inpatient rotation experience. We compared the proportions of âsuperiorâ ratings versus all other ratings prior to the educational intervention (2005â2006, baseline) with the two subsequent years post intervention (2006â2007, year 1; 2007â2008, year 2). We also compared medical student scores on a comprehensive National Board of Medical Examiners clinical subject examination pre and post intervention.
Results:
When compared to the baseline year, pediatric residents were more likely to rate as superior the quality of didactic teaching (OR=1.7 [1.0-2.8] year 1; OR=2.0 [1.1-3.5] year 2) and attendingsâ appeal as a role model (OR=1.9 [1.1-3.3] year 2). Residents were also more likely to rate as superior the quality of feedback and evaluation they received from the attending (OR=2.1 [1.2-3.7] year 1; OR=3.9 [2.2-7.1] year 2). Similar improvements were also noted in medical student evaluations of faculty attendings. Most notably, medical students were significantly more likely to rate feedback on their data gathering and physical examination skills as superior (OR=4.2 [2.0-8.6] year 1; OR=6.4 [3.0-13.6] year 2).
Conclusions:
A comprehensive program which includes clear role descriptions along with faculty expectations, as well as salary support for faculty in clinical and educational roles, can improve resident and medical student experiences on a general pediatric inpatient service. The authors provide sufficient detail to replicate this program to other settings.JH Libraries Open Access Promotion Fun
Photonic quantum information processing: a review
Photonic quantum technologies represent a promising platform for several
applications, ranging from long-distance communications to the simulation of
complex phenomena. Indeed, the advantages offered by single photons do make
them the candidate of choice for carrying quantum information in a broad
variety of areas with a versatile approach. Furthermore, recent technological
advances are now enabling first concrete applications of photonic quantum
information processing. The goal of this manuscript is to provide the reader
with a comprehensive review of the state of the art in this active field, with
a due balance between theoretical, experimental and technological results. When
more convenient, we will present significant achievements in tables or in
schematic figures, in order to convey a global perspective of the several
horizons that fall under the name of photonic quantum information.Comment: 36 pages, 6 figures, 634 references. Updated version with minor

Image of Neighborhood, Self-Image, Sense of Community
The present study was carried out on a sample of residents of three Italian cities (N Âź 1031) to pursue two aims: (a) to explore the relationship between the images of the community of residence and sense of community, and (b) to investigate the relationship between self and neighborhood images. In order to identify neighborhood and self-image, free associations of words to the statements ââmy neighborhood isââ and ââI amââ underwent a cluster analysis; then a correspondence analysis between these two types of representations and the sense of community level was performed. Results showed a relationship between the subjective image of the neighborhood and sense of community, but did not point out a clear relation between self and neighborhood images. Theoretical and empirical implications are discussed
Tomographic characterisation of correlations in a photonic tripartite state
Starting from a four-partite photonic hyper-entangled Dicke resource, we
report the full tomographic characterization of three-, two-, and one-qubit
states obtained by projecting out part of the computational register. The
reduced states thus obtained correspond to fidelities with the expected states
larger than 87%, therefore certifying the faithfulness of the
entanglement-sharing structure within the original four-qubit resource. The
high quality of the reduced three-qubit state allows for the experimental
verification of the Koashi-Winter relation for the monogamy of correlations
within a tripartite state. We show that, by exploiting the symmetries of the
three-qubit state obtained upon projection over the four-qubit Dicke resource,
such relation can be experimentally fully characterized using only 5
measurement settings. We highlight the limitations of such approach and sketch
an experimentally-oriented way to overcome them.Comment: 13 pages, 5 figure
