Traumatic hyphaema following successive vacuum and forceps-assisted delivery
Hyphaema can cause corneal staining and is a potential risk for glaucoma. We report a case of a neonate with isolated traumatic hyphaema following a prolonged delivery with the consecutive use of vacuum and forceps. A review the literature discusses reports of ophthalmic injuries associated with assisted vaginal deliveries.peer-reviewe
Organizational Cultures Effect on Productivity in Manufacturing
Manufacturing industry continues to struggle due to the inability to fill scheduled orders as a result a depleted workforce. Now more than ever, the importance of sustaining a workforce is essential to the success or failure of an organization. Organizational culture initiatives such as job satisfaction, employee commitment, and employee motivation represent a pivotal addition to all organizations. A strong leadership foundation that can develop and establish strong working cultures by utilizing these initiatives to retain employees is imperative to combat high employee turnover, low morale, and decreased productivity. The study has been affected by a qualitative approach, employing a single case study to acquire understanding of how strong leadership and a positive organizational culture helps institute a strong working culture in manufacturing. Developing a strong foundation of leaders and developing a genuine organizational culture will occur through calculated training and development of leaders. Participant responses revealed these discovered themes to include (a) positive company culture, (b) employee engagement, (c) job satisfaction, (d) leadership effectiveness, (e) and communication
Coping with Economic Stressors: Religious and Non-Religious Strategies for Managing Psychological Distress
The current economic downturn has increased concerns over job insecurity and the potential negative effects of job insecurity and other economic stressors for individuals. While there is a great deal of research on traditional (non-religious) methods of coping with work stress (e.g., Latack, 1986), there has been little research concerning the impact of religious methods of coping on mitigating the effects of work-related stressors. This is true even though a significant amount of research has demonstrated that religious coping methods are effective at reducing negative effects of a wide variety of stressors. Specifically, the current study looked at the effectiveness of religious and non-religious coping strategies when dealing with economic stressors. Seeking Support from Clergy or Members is the only significant moderator of the relationship between job insecurity and psychological distress. In addition, both non-religious and religious coping strategies account for unique variance in psychological distress. However, non-religious coping strategies explain more unique variance than religious coping strategies. Future directions for research and limitations are discussed
Holographic Operator Mixing and Quasinormal Modes on the Brane
We provide a framework for calculating holographic Green's functions from
general bilinear actions and fields obeying coupled differential equations in
the bulk. The matrix-valued spectral function is shown to be independent of the
radial bulk coordinate. Applying this framework we improve the analysis of
fluctuations in the D3/D7 system at finite baryon density, where the
longitudinal perturbations of the world-volume gauge field couple to the scalar
fluctuations of the brane embedding. We compute the spectral function and show
how its properties are related to the quasinormal mode spectrum. We study the
crossover from the hydrodynamic diffusive to the reactive regime and the
movement of quasinormal modes as functions of temperature and density. We also
compute their dispersion relations and find that they asymptote to the
lightcone for large momenta.Comment: 42 pages, 12 figure
IN-SYNC. VII. Evidence for a decreasing spectroscopic binary fraction from 1 to 100 Myr within the IN-SYNC sample
We study the occurrence of spectroscopic binaries in young star-forming
regions using the INfrared Spectroscopy of Young Nebulous Clusters(IN-SYNC)
survey, carried out in SDSS-III with the APOGEE spectrograph. Multi-epoch
observations of thousands of low-mass stars in Orion A, NGC 2264, NGC 1333, IC
348, and the Pleiades have been carried out, yielding H-band spectra with a
nominal resolution of R=22,500 for sources with H 12 mag. Radial velocity
precisions of 0.3 were achieved, which we use to identify
radial velocity variations indicative of undetected companions. We use Monte
Carlo simulations to assess the types of spectroscopic binaries to which we are
sensitive, finding sensitivity to binaries with orbital periods d,
for stars with and 100 . Using Bayesian inference, we find evidence
for a decline in the spectroscopic binary fraction, by a factor of 3-4 from the
age of our pre-main-sequence sample to the Pleiades age . The significance of
this decline is weakened if spot-induced radial-velocity jitter is strong in
the sample, and is only marginally significant when comparing any one of the
pre-main-sequence clusters against the Pleiades. However, the same decline in
both sense and magnitude is found for each of the five pre-main-sequence
clusters, and the decline reaches statistical significance of greater than 95%
confidence when considering the pre-main-sequence clusters jointly. Our results
suggest that dynamical processes disrupt the widest spectroscopic binaries
( d) as clusters age, indicating that this
occurs early in the stars' evolution, while they still reside within their
nascent clusters.Comment: 21 pages, 9 Figure
Supersonic Technology Concept Aeroplanes for Environmental Studies
The International Civil Aviation Organization is considering new environmental standards for future supersonic civil aircraft. NASA is supporting this effort by analyzing several notional, near-term supersonic transports. NASAs performance, noise, and exhaust emission predictions for these transports are being used to inform a larger study that will determine the global environmental and economic impact of adding supersonic aircraft to the fleet beginning this decade. A supersonic business jet with a maximum takeoff gross weight of 55 tonnes is the focus of this paper. A smaller business jet weighing 45 tonnes is also discussed. Both airplanes use supersonic engines derived from a common contemporary commercial subsonic turbofan core. Aircraft performance, airport-vicinity noise, and exhaust emissions are predicted using NASA tools. Also investigated are some of the anticipated behaviors and requirements of these aircraft in the commercial airspace. The sensitivity of noise to system uncertainties is presented and alternative engine studies are discussed
