Tips for a Physician in Getting the Right Job, Part XXI: Introduction to Contract Negotiations.

Those physicians who have excellent job prospects, and preferably have more than one offer, may wish to try to negotiate better terms for their employment contract than was initially offered. However, any negotiation must be done in a friendly, polite, and professional manner. This article gives many tips regarding contract negotiations. However, the employment contract should be discussed with the job seeker's family and attorney before signing it.

Tips for a Physician in Getting the Right Job, Part XXII: More on Contract Negotiations.

This article discusses contract negotiations on multiple issues including bonuses, restrictive covenants, and fringe benefits. However, the job seeker should be very careful about attempting to negotiate what is already a very good contract if he/she does not have alternative employment opportunities or is not a very strong candidate. In addition, often more important than the contract is the character of the people the job seeker would be working for. If the employers do not seem to be honorable, it is usu...

Aircraft noise and speech intelligibility in an outdoor living space.

Studies of effects on speech intelligibility from aircraft noise in outdoor places are currently lacking. To explore these effects, first-order ambisonic recordings of aircraft noise were reproduced outdoors in a pergola. The average background level was 47 dB LA eq. Lists of phonetically balanced words (LAS max,word = 54 dB) were reproduced simultaneously with aircraft passage noise (LAS max,noise = 72-84 dB). Twenty individually tested listeners wrote down each presented word while seated in...

Polarized Imaging Nephelometer for in situ airborne measurements of aerosol light scattering.

Global satellite remote sensing of aerosols requires in situ measurements to enable the calibration and validation of algorithms. In order to improve our understanding of light scattering by aerosol particles, and to enable routine in situ airborne measurements of aerosol light scattering, we have developed an instrument, called the Polarized Imaging Nephelometer (PI-Neph). We designed and built the PI-Neph at the Laboratory for Aerosols, Clouds and Optics (LACO) of the University of Maryland, Baltimore Cou...

Subjective Evaluation of Physical and Mental Workload Interactions across Different Muscle Groups.

ABSTRACT Both physical and mental demands, and their interactions, have shown to increase biomechanical loading and physiological reactivity, as well as impair task performance. Because these interactions have shown to be muscle-dependent, the aim of this study was to determine the sensitivity of the NASA Task Load Index (NASA TLX) and Ratings of Perceived Exertion (RPE) to evaluate physical and mental workload during muscle-specific tasks. Twenty-four participants performed upper extremity and low back exe...

Augmented reality for aircraft maintenance training and operations support.

Recent statistics on causes of aviation accidents and incidents demonstrate that to increase air-transportation safety, we must reduce human errors' impact on operations. So, the industry should first address human factors related to people in stressful roles to significantly minimize such errors. In particular, aviation maintenance employees work under high-pressure conditions- that is, they're under strict time constraints and must adhere to stringent guidelines. Because of such constraints, they might be...

The application of magnetic measurements for the characterization of atmospheric particulate pollution within the airport environment.

The significant increase in global air travel which has occurred during the last fifty years has generated growing concern regarding the potential impacts associated with increasing emissions of atmospheric particulate matter (PM) on health and the environment. PM within the airport environment may be derived from a range of sources. To date, however, the identification of individual sources of airport derived PM has remained elusive but constitutes a research priority for the aviation industry. The aim of ...

Ubiquity and Diversity of Heterotrophic Bacterial nasA Genes in Diverse Marine Environments.

Nitrate uptake by heterotrophic bacteria plays an important role in marine N cycling. However, few studies have investigated the diversity of environmental nitrate assimilating bacteria (NAB). In this study, the diversity and biogeographical distribution of NAB in several global oceans and particularly in the western Pacific marginal seas were investigated using both cultivation and culture-independent molecular approaches. Phylogenetic analyses based on 16S rRNA and nasA (encoding the large subunit of the ...

Maintenance: The Key to Successful Periodontal and Implant Therapy.

The management of periodontal diseases requires an effective treatment and maintenance program, as well as collaboration among clinicians. Having a better understanding of the factors contributing to periodontal maintenance is key. The components of a maintenance program and determining proper intervals ensure that patients increase their chances for maintaining their teeth and implants in an optimal state of health..

Fault tolerant attitude control for small unmanned aircraft systems equipped with an airflow sensor array.

Inspired by sensing strategies observed in birds and bats, a new attitude control concept of directly using real-time pressure and shear stresses has recently been studied. It was shown that with an array of onboard airflow sensors, small unmanned aircraft systems can promptly respond to airflow changes and improve flight performances. In this paper, a mapping function is proposed to compute aerodynamic moments from the real-time pressure and shear data in a practical and computationally tractable formulati...

Review of NASA Approach to Space Radiation Risk Assessments for Mars Exploration.

Long duration space missions present unique radiation protection challenges due to the complexity of the space radiation environment, which includes high charge and energy particles and other highly ionizing radiation such as neutrons. Based on a recommendation by the National Council on Radiation Protection and Measurements, a 3% lifetime risk of exposure-induced death for cancer has been used as a basis for risk limitation by the National Aeronautics and Space Administration (NASA) for low-Earth orbit mis...

NASA ASTRONAUTS, PROSTHETICS AND THE MANNED SPACE PROGRAM.

The author has collaborated with NASA astronauts, scientists and engineers since 2006. Manned deep space missions, beyond the Moon’s orbit, are being planned in this post-Shuttle era. The spacecraft required for longer flights will have relatively restricted crew interior volume. To decrease the negative impact of these tight quarters, the author has proposed recruiting smaller astronauts (abbreviated SAs), persons about one-half the height of current near-Earth crewmembers. This includes achondroplastic d...

Modeling Flight Attendants' Exposure to Secondhand Smoke in Commercial Aircraft: Historical Trends from 1955 to 1989.

Flight attendants were exposed to elevated levels of secondhand smoke (SHS) in commercial aircraft when smoking was allowed on planes. During flight attendants' working years, their occupational SHS exposure was influenced by various factors, including the prevalence of active smokers on planes, fliers' smoking behaviors, airplane flight load factors, and ventilation systems. These factors have likely changed over the past six decades and would affect SHS concentrations in commercial aircraft. However, chan...
