Reanalysis of the spectrum of the z=10 galaxy

In a recent paper Pello et al. reported observations of a faint galaxy, gravitationally lensed by the galaxy cluster Abell 1835. Deep J-band spectroscopy revealed a weak emission line near 1.34 microns, detected in two spectra with different central wavelengths. The line was interpreted as Lyman-alpha at redshift z=10.0. This interpretation is supported by the broad-band photometric spectral energy distribution, and by the location of the galaxy close to the lens critical line for this redshift. We have reanalysed the two spectra, just released from the data archive. Our analysis includes allowance for wavelength shifts due to transverse drift of the object in the slit. We do not detect a significant emission line at the reported location, or nearby, at either grating setting, nor in the combined spectrum. We provide a possible explanation for the reported detection as due to spurious positive flux introduced in the sky-subtraction stage as a result of variable hot pixels. We provide our final reduced 2D frame, and corresponding error array.Comment: 4 pages, 1 figure. To appear in A&A Letters. Added possible explanation for reported emission line as due to variable hot pixel

A feasibility study: Forest Fire Advanced System Technology (FFAST)

The National Aeronautics and Space Administration/Jet Propulsion Laboratory and the United States Department of Agriculture Forest Service completed a feasibility study that examined the potential uses of advanced technology in forest fires mapping and detection. The current and future (1990's) information needs in forest fire management were determined through interviews. Analysis shows that integrated information gathering and processing is needed. The emerging technologies that were surveyed and identified as possible candidates for use in an end to end system include ""push broom'' sensor arrays, automatic georeferencing, satellite communication links, near real or real time image processing, and data integration. Matching the user requirements and the technologies yielded a ""strawman'' system configuration. The feasibility study recommends and outlines the implementation of the next phase for this project, a two year, conceptual design phase to define a system that warrants continued development

Submicrosecond comparison of international clock synchronization by VLBI and the NTS satellite

The intercontinental clock synchronization capabilities of Very Long Baseline Interferometry (VLBI) and the Navigation Technology Satellite (NTS) were compared using both methods to synchronize the Cesium clocks at the NASA Deep Space Net complexes at Madrid, Spain and Goldstone, California. Verification of the accuracy of both systems was examined. The VLBI experiments used the Wideband VLBI Data Acquisition System developed at the NASA Jet Propulsion Laboratory. The NTS Satellites were designed and built by the Naval Research Laboratory used with NTS Timing Receivers developed by the Goddard Space Flight Center. The two methods agreed at about the one-half microsecond level

The effect of a multi-component intervention on disrespect and abuse during childbirth in Kenya

Background Disrespect and abuse (D & A) during labor and delivery are important issues correlated with human rights, equity, and public health that also affect women’s decisions to deliver in facilities, which provide appropriate management of maternal and neonatal complications. Little is known about interventions aimed at lowering the frequency of disrespectful and abusive behaviors. Methods Between 2011 and 2014, a pre-and-post study measured D & A levels in a three-tiered intervention at 13 facilities in Kenya under the Heshima project. The intervention involved working with policymakers to encourage greater focus on D & A, training providers on respectful maternity care, and strengthening linkages between the facility and community for accountability and governance. At participating facilities, postpartum women were approached at discharge and asked to participate in the study; those who consented were administered a questionnaire on D & A in general as well as six typologies, including physical and verbal abuse, violations of confidentiality and privacy, detainment for non-payment, and abandonment. Observation of provider-patient interaction during labor was also conducted in the same facilities. In both exit interview and observational studies, multivariate analyses of risk factors for D & A controlled for differences in socio-demographic and facility characteristics between baseline and endline surveys. Results Overall D & A decreased from 20–13 % (p < 0.004) and among four of the six typologies D & A decreased from 40–50 %. Night shift deliveries were associated with greater verbal and physical abuse. Patient and infant detainment declined dramatically from 8.0–0.8 %, though this was partially attributable to the 2013 national free delivery care policy. Conclusion Although a number of contextual factors may have influenced these findings, the magnitude and consistency of the observed decreases suggest that the multi-component intervention may have the potential to reduce the frequency of D & A. Greater efforts are needed to develop stronger evaluation methods for assessing D & A in other settings

Decomposition of the visible and dark matter in the Einstein ring 0047-2808 by semi-linear inversion

We measure the mass density profile of the lens galaxy in the Einstein ring system 0047-2808 using our semi-linear inversion method developed in an earlier paper. By introducing an adaptively gridded source plane, we are able to eliminate the need for regularisation of the inversion. This removes the problem of a poorly defined number of degrees of freedom, encountered by inversion methods that employ regularisation, and so allows a proper statistical comparison between models. We confirm the results of Wayth et al. (2004), that the source is double, and that a power-law model gives a significantly better fit that the singular isothermal ellipsoid model. We measure a slope alpha=2.11+/-0.04. We find, further, that a dual-component constant M/L baryonic + dark halo model gives a significantly better fit than the power-law model, at the 99.7% confidence level. The inner logarithmic slope of the dark halo profile is found to be 0.87^{+0.69}_{-0.61} (95% CL), consistent with the predictions of CDM simulations of structure formation. We determine an unevolved B-band mass to light ratio for the baryons (only) of 3.05^{+0.53}_{-0.90} h_65 M_sol/L_Bsol (95% CL). This is the first measurement of the baryonic M/L of a single galaxy by purely gravitational lens methods. The baryons account for 65^{+10}_{-18}% (95% CL) of the total projected mass, or, assuming spherical symmetry, 84^{+12}_{-24}% (95% CL) of the total three-dimensional mass within the mean radius of 1.16'' (7.5 h_65^{-1} kpc) traced by the ring. Finally, at the level of >3sigma, we find that the halo mass is rounder than the baryonic distribution and that the two components are offset in orientation from one another.Comment: 17 pages, 5 figures, accepted by ApJ on 17/12/05.

A Competency-based Approach to Faculty Development

Background—Faculty development at the Virginia Commonwealth University School of Medicine (VCU SOM) has previously focused on enhancing teaching and learning in the medical and clinical education settings. While this work is important, this narrow focus does not address all facets a faculty member’s role. To broaden their programming, the VCU SOM faculty development team adopted a competency-based approach to the development and planning of faculty development activities. Summary of work—The Senior Associate Dean for Faculty Affairs completed a research project focused on successful medical faculty who promote through the tenure process and advance in their careers. She identified the following categories for success: teaching, service, scholarship, advancing, and leadership. Each of these categories contains action-focused competencies that align with career progression addressing early, mid, and late career stages. The faculty development team adopted the identified competencies to their curriculum development and planning processes. Summary of results—The results of this adoption have been clearer goals for learners, a mapped structure for faculty development activities, and a broader range of topics offered that align with career stages. Discussion—Faculty development activities are now categorized into five (5) categories: Teach, Lead, Serve, Discover, and Advance with each category color coded for easy recognition in event marketing materials. A new logo reflecting these competency categories is now included on all Office of Faculty Affairs communications. Faculty are beginning to recognize and register for activities they need for promotion, tenure, and advancement. Conclusions—The adoption of the competencies for success from the Senior Associate Dean’s study has enriched faculty development offerings providing a recognizable structure allowing faculty to easily identify competency areas for development

Supporting Special-Purpose Health Care Models via Web Interfaces

The potential of the Web, via both the Internet and intranets, to facilitate development of clinical information systems has been evident for some time. Most Web-based clinical workstations interfaces, however, provide merely a loose collection of access channels. There are numerous examples of systems for access to either patient data or clinical guidelines, but only isolated cases where clinical decision support is presented integrally with the process of patient care, in particular, in the form of active alerts and reminders based on patient data. Moreover, pressures in the health industry are increasing the need for doctors to practice in accordance with ¿best practice¿ guidelines and often to operate under novel health-care arrangements. We present the Care Plan On-Line (CPOL) system, which provides intranet-based support for the SA HealthPlus Coordinated Care model for chronic disease management. We describe the interface design rationale of CPOL and its implementation framework, which is flexible and broadly applicable to support new health care models over intranets or the Internet
