Managing professional identity within a changing market environment: New Zealand optometrists’ responses to the growth of corporate optometry

This research investigated the effects of changes in the market environment for optometry services and products on the professional identity of New Zealand optometrists. It explored three issues. First, ways participants’ location within either the independent or corporate sectors shaped their professional identities. Second, ways potential ethical conflicts between participants’ healthcare and retailing identities were resolved. Last, participants’ opinions concerning the future of their profession. Twelve male and fourteen female optometrists were interviewed. Nineteen participants worked within independent optometry practices. Seven worked within practices that were part of international optometry chains. Six participants were recent graduates, the rest experienced optometrists. All participants identified primarily as healthcare professionals. All recognised that practising optometry within a commercial market created the possibility of ethical conflicts between healthcare and business imperatives. There were differences in the ways participants managed this boundary, with participants working within corporate optometry seeming more comfortable with the business aspects of their profession. All participants thought the profession was changing and several suggested that the future of independent optometry was limited. The article concludes that recent changes within the market environment of optometry have heightened tensions between optometrists’ medical and entrepreneurial identities and contributed to changing work patterns within the profession.fals

Evidence for Rotation in the Galaxy at z=3.15 Responsible for a Damped Lyman-alpha Absorption System in the Spectrum of Q2233+1310

Proof of the existence of a significant population of normal disk galaxies at redshift z>2 would have profound implications for theories of structure formation and evolution. We present evidence based on Keck HIRES observations that the damped Lyman-alpha absorber at z=3.15 toward the quasar Q2233+1310 may well be such an example. Djorgovski et al have recently detected the Lyman-alpha emission from the absorber, which we assume is at the systemic redshift of the absorbing galaxy. By examining the profiles of the metal absorption lines arising from the absorbing galaxy in relation to its systemic redshift, we find strong kinematical evidence for rotation. Therefore the absorber is likely to be a disk galaxy. The inferred circular velocity for the galaxy is >200 km/s. With a separation of ~17 kpc between the galaxy and the quasar sightline, the implied dynamic mass for the galaxy is >1.6x10(11) solar mass. The metallicity of the galaxy is found to be [Fe/H]=-1.4, typical of damped Lyman-alpha galaxies at such redshifts. However, in another damped galactic rotation is evident. In the latter case, the damped Lyman-alpha absorber occurs near the background quasar in redshift so its properties may be influenced by the background quasar. These represent the only two cases at present for which the technique used here may be applied. Future applications of the same technique to a large sample of damped Lyman-alpha galaxies may allow us to determine if a significant population of disk galaxies already existed only a few billion years after the Big Bang.Comment: AASTEX, 2 PS figures, accepted by ApJ, 6 pages total, replaced on 1-22-97, the only change is the enlarged figure

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

Feasibility study of a synthesis procedure for array feeds to improve radiation performance of large distorted reflector antennas

Sloan Digital Sky Survey Spectroscopic Lens Search. I. Discovery of Intermediate-Redshift Star-Forming Galaxies Behind Foreground Luminous Red Galaxies

We present a catalog of 49 spectroscopic strong gravitational lens candidates selected from a Sloan Digital Sky Survey sample of 50996 luminous red galaxies. Potentially lensed star-forming galaxies are detected through the presence of background oxygen and hydrogen nebular emission lines in the spectra of these massive foreground galaxies. This multiline selection eliminates the ambiguity of single-line identification and provides a very promising sample of candidate galaxy-galaxy lens systems at low to intermediate redshift, with foreground redshifts ranging from 0.16 to 0.49 and background redshifts from 0.25 to 0.81. Any lenses confirmed within our sample would be important new probes of early-type galaxy mass distributions, providing complementary constraints to those obtained from currently known lensed high-redshift quasars.Comment: 23 pages; to appear in The Astronomical Journal, 2004 April.

Test results of the Chrysler upgraded automotive gas turbine engine: Initial design

The upgraded engine as built to the original design was deficient in power and had excessive specific fuel consumption. A high instrumented version of the engine was tested to identify the sources of the engine problems. Analysis of the data shows the major problems to be low compressor and power turbine efficiency and excessive interstage duct losses. In addition, high HC and CO emission were measured at idle, and high NOx emissions at high energy speeds
