Home Health Aides\u27 Performance and Home Health Clients\u27 Quality of Life
Home health aides\u27 performance can help home health clients achieve quality of life. This quantitative, cross-sectional study examined which work-related factors of home health aides influence home health clients\u27 quality of life. A socioecological perspective was used to understand influences on behaviors. Participants in this study were 400 home health clients who received services from home health agencies. A binary logistic model was used to determine the predictor variables of home health aides that contributed to home health clients\u27 quality of life. Findings indicated that psychosocial skills were among the most predicted work-related performance of home health aides that lead to quality of life for home health clients. All independent variables (professional care; teaching clients about medication management, pain, and home safety; and social and communication skills) showed significance (p \u3c .05). The implications of this study for positive social change include contributing evidence to support improving home health practices and informing policies, which might increase the quality of life for home health clients
Seven steps to successful change: How a large academic medical center prepared patients for organizational change
Vanderbilt University Medical Center (VUMC) launched a new electronic health record (EHR) in a âbig bangâ implementation that saw the new software go live across multiple hospitals, clinics and geographic locations in a single morning. The organization rightly focused most of its energy on preparing its nearly 25,000 employees for the impacts of the transition, but it also considered the effects that would be felt by its patients and families. Survey data indicate that patient satisfaction scores demonstrably dip before, during and after an EHR implementation, and take approximately a year to recover. A team at DMC employed a seven-step approach to preparing patients for the impacts of the transition, which led to a return to pre-implementation patient satisfaction scores in about half the time of its peer institutions. The article explores these seven steps in detail and offers recommendations for how healthcare organizations facing large-scale change can use a similar structured approach to mitigate negative impacts to patients.

The Interplanetary Network Supplement to the BeppoSAX Gamma-Ray Burst Catalogs
Between 1996 July and 2002 April, one or more spacecraft of the
interplanetary network detected 787 cosmic gamma-ray bursts that were also
detected by the Gamma-Ray Burst Monitor and/or Wide-Field X-Ray Camera
experiments aboard the BeppoSAX spacecraft. During this period, the network
consisted of up to six spacecraft, and using triangulation, the localizations
of 475 bursts were obtained. We present the localization data for these events.Comment: 89 pages, 3 figures. Submitted to the Astrophysical Journal

Dynamics of DNA Ejection From Bacteriophage
The ejection of DNA from a bacterial virus (``phage'') into its host cell is
a biologically important example of the translocation of a macromolecular chain
along its length through a membrane. The simplest mechanism for this motion is
diffusion, but in the case of phage ejection a significant driving force
derives from the high degree of stress to which the DNA is subjected in the
viral capsid. The translocation is further sped up by the ratcheting and
entropic forces associated with proteins that bind to the viral DNA in the host
cell cytoplasm. We formulate a generalized diffusion equation that includes
these various pushing and pulling effects and make estimates of the
corresponding speed-ups in the overall translocation process. Stress in the
capsid is the dominant factor throughout early ejection, with the pull due to
binding particles taking over at later stages. Confinement effects are also
investigated, in the case where the phage injects its DNA into a volume
comparable to the capsid size. Our results suggest a series of in vitro
experiments involving the ejection of DNA into vesicles filled with varying
amounts of binding proteins from phage whose state of stress is controlled by
ambient salt conditions or by tuning genome length.Comment: 17 pages, 5 figure
A Longitudinal Study of Teaching Practice and Early Career Decisions: A Cautionary Tale
Although the turnover rate among beginning teachers has been a major concern for some time, most studies do not link teacher retention with teaching practice. In contrast, this study looks specifically at career decisions coupled with practice. Guided by a view of teaching as social and cultural practice, the study used multiple qualitative data sources, including extensive observations, interviews, and samples of teachersâ and studentsâ work. Based on within and cross-case analysis of 15 cases at four distinct time points within a 5-year period, the authors identified multiple patterns of teaching practice linked to early career decisions, which reflect considerable variation in quality of teaching and career trajectory. The authors argue that ââstayersââ and ââleaversââ are not homogeneous groups, as is often assumed in research and policy. Rather, there are multiple variations of practice coupled with career decisions, some desirable and others not, with different implications for policy and practice

Interpreting Early Career Trajectories
Career decisions of four teachers are explored through the concept of figured worlds in this qualitative, longitudinal case study. Participants were purposefully chosen for similarity at entry, with a range of career trajectories over time. Teacher career paths included remaining in one school, repeated changes in schools, attrition after relocation, and nonrenewal of contract. Data included interviews, observations, participantsâ assessments, and pupilsâ work. Cross-case analysis suggests that no single teacher attribute or workplace condition determined teachersâ career decisions; rather, teachersâ ability to refigure their identity within the figured world of teaching shaped career trajectory. Key factors such as ability to address disequilibrium, teacher identity, agency, and collaborative capacity are examined. Implications call for pre-service preparation and professional development to navigate cultures of schools, amended administrative involvement in teacher retention, and policy reform acknowledging the complexity of teachersâ figured worlds
APASS Landolt-Sloan BVgri photometry of RAVE stars. I. Data, effective temperatures and reddenings
We provide APASS photometry in the Landolt BV and Sloan g'r'i' bands for all
the 425,743 stars included in the latest 4th RAVE Data Release. The internal
accuracy of the APASS photometry of RAVE stars, expressed as error of the mean
of data obtained and separately calibrated over a median of 4 distinct
observing epochs and distributed between 2009 and 2013, is 0.013, 0.012, 0.012,
0.014 and 0.021 mag for B, V, g', r' and i' band, respectively. The equally
high external accuracy of APASS photometry has been verified on secondary
Landolt and Sloan photometric standard stars not involved in the APASS
calibration process, and on a large body of literature data on field and
cluster stars, confirming the absence of offsets and trends. Compared with the
Carlsberg Meridian Catalog (CMC-15), APASS astrometry of RAVE stars is accurate
to a median value of 0.098 arcsec. Brightness distribution functions for the
RAVE stars have been derived in all bands. APASS photometry of RAVE stars,
augmented by 2MASS JHK infrared data, has been chi2 fitted to a densely
populated synthetic photometric library designed to widely explore in
temperature, surface gravity, metallicity and reddening. Resulting Teff and
E(B-V), computed over a range of options, are provided and discussed, and will
be kept updated in response to future APASS and RAVE data releases. In the
process it is found that the reddening caused by an homogeneous slab of dust,
extending for 140 pc on either side of the Galactic plane and responsible for
E(B-V,poles)=0.036 +/- 0.002 at the galactic poles, is a suitable approximation
of the actual reddening encountered at Galactic latitudes |b|>=25 deg.Comment: Astronomical Journal, in press. Resolution of Figures degrated to

Understanding Spectral Variability and Time Lags in Accreting Black Holes
I review the temporal/spectral data of accreting black hole sources paying
most attention to the properties of the temporal variability such as photon
energy dependent auto- and cross-correlation functions, average shot profiles
and hardness ratios, and the Fourier frequency dependent time/phase lags. These
statistics characterize spectral changes at short time scales that are
otherwise impossible to study by direct spectral analysis. The data provide
strong constraints on the theoretical models for X-ray production in accreting
black holes. Models for the spectral variability of the Comptonized component
are briefly reviewed. It is also shown that Compton reflection can have
significant impact on the observed temporal characteristics.Comment: 14 pages; Invited review at the 33rd COSPAR Scientific Assembly,
